Drying large amounts of ambient air is not easy by any means. However, desiccants are perhaps the most effective way to do this for enclosed air systems.

Therefore, desiccant air dryers are widely used for industrial purposes, wherever there is a need for dry, moisture-free air. However, the desiccants in these dryers don’t last forever, which leads many to ask, “how long does air dryer desiccant last?”

Let’s discuss desiccant materials, their types, desiccant air dryers, how they work, and more to answer this question.

What are Desiccant Materials?

Desiccants are highly effective materials or substances that absorb moisture and water vapour from the air, especially from enclosed air systems. They have hygroscopic properties, which means they have an affinity for water. They can absorb and retain water molecules to maintain a dry environment.

Types of Desiccant Materials

There are plenty of desiccant materials, many of which are chemically stable. However, some are also toxic, so they can only be used under specific circumstances. Here are a few types of desiccant materials commonly used for their hygroscopic properties.

  • Activated Charcoal
  • Silica
  • Aluminosilicate minerals
  • Calcium Sulphate
  • Calcium Chloride

These desiccants are used in a wide range of applications, from silica gel packets in product packaging to industrial compressed air drying with desiccant air dryers.

What Is a Desiccant Air Dryer?

Desiccant air dryers are industrial machines or equipment that uses desiccants to absorb moisture and water from compressed air that is being passed through it. They are highly effective for absorbing moisture from closed and compressed air systems, making them very useful for certain industrial purposes.

A typical desiccant air dryer is designed with two towers containing desiccant materials to help make sure that a continuous air drying cycle is maintained throughout the process.

How Does a Desiccant Air Dryer Work?

Desiccant materials can only hold a limited amount of water molecules before they stop absorbing. As mentioned above, a typical desiccant air dryer contains two towers. These towers hold equal amounts of desiccant materials inside and work in opposing functions.

While one tower actively absorbs moisture and water molecules from the passing compressed air, the other tower releases moisture from the desiccant in a reverse process known as regeneration. It essentially regenerates the desiccant material to make space for more water molecules later.

There are two regeneration methods in desiccant air dryers, one that uses heat and another that doesn’t. There are two types of desiccant air dryers, heat-generating dryers, and heatless dryers.

Regardless of type, when the desiccants in the absorbing tower reach full absorption capacity and the desiccants in the regeneration tower are dry enough to take over, the control unit flips its functions. The absorbing tower starts regenerating the saturated desiccants inside it, whereas the regeneration tower starts absorbing moisture from the passing compressed air.

This function flip allows the desiccant air dryer to continually dry the passing compressed air without stopping for regeneration purposes. However, the desiccant materials inside the dryer tend to lose some of their hygroscopic properties with each cycle, which means they don’t last forever, and you need to replace them over time.

This brings us to our key question.

How Long Does Air Dryer Desiccant Last?

Air dryer desiccant can last up to 5 years in heatless dryers, but only with proper care and maintenance, including maintenance of separators and filters used inside the dryer. On the other hand, heat-generating dryer desiccant lasts around 2-3 years before it needs to be replaced.

The latter doesn’t last as long due to the accelerated regeneration process that speeds up the loss of the desiccant material’s hygroscopic properties. However, the quicker regeneration and dryer cycles are worth it for specific industrial applications, which is why this type of desiccant air dryer exists.


after, you should have a good idea of what desiccant materials are, their types, what desiccant heat dryers are, how they work, and most importantly, “how long does air dryer desiccant last?” There is a lot more to desiccant materials and desiccant air dryers that we haven’t mentioned, but we can discuss that another time.

How Does This Shampoo Work?

It is not a clarifying shampoo. In fact, it is much more. The sebum that your scalp emits is designed for many positive purposes however when bacteria, yeast, and fungus get involved the oils can mix and create hardened crusty patches on the head or behind the ears, back of the head, eyebrows, beard, and wherever hair grows.

This is an imbalance and for lasting results from the above-mentioned you will need to not only remove the hardened sebum as well as product buildup as such but you will need to help flush out the hair follicle of the bacteria, fungus and yeast as well. The herbs in this scalp gunk shampoo are designed to o just that. Clean the scalp pores from the very root, the follicle itself, and the shaft of the hair along with the skin on the head while helping to balance the ph which is one of the most important things that you can do.


So What Is The Real Problem and What Can You Do?


Follicle Buildup Clogs have follicles. Inside the hair follicles bacteria, fungus, and yeast mix with the oils. The hair follicle is then pinched from the inflammation. Many of you have heard about The fungus is called Malassezia furfur as it pertains to scalp issues such as dandruff and seborrheic dermatitis or seborrhea. But remember everyone has this fungus on their scalp. If you are having problems or issues with your scalp then the odds are that yours are out of balance.


What Causes This Imbalance?


The skin has a natural barrier to fungus of all kinds. However for this to work properly it has to be at an optimal ph. 98% of shampoos out there change the ph. Another issue is that over time sebum build-up and even plugs can trap bacteria and fungus inside the follicle. This can mean both are running rampant. When trapped inside the follicle you can get bumps, white, red, and more. You can also get sores, blisters, waxy build-up, best oily scalp dandruff shampoo, white scalp gunk shampoo, crusty, sebum plugs and any of these can be intense. The trick is open the sebum plugs and balances the ph. However, you must also destroy the bacterial and fungus issues.

This Shampoo Has Been Voted To The Top For Nearly 20 Years For Scalp Issues!

1) Herbal Extract Combination that includes thymus-thyme, sage, Vulgaris extracts, and burdock-articum. Together these loosen up the dirt and sebum mixture. They work on the sebum plugs to open them and then this allows the herbs to irrigate the bacteria and fungus

2) Zinc is known as nature’s topical antibiotic and anti-fungal mineral. This is one of the main difference makers for these products.

3) Feeds The Root like most products do not. Articum is also a mild blood vessel stimulant to help create optimal hair growth.

4) Sticky Hair Sprays, Gels, Sticky Shampoo Residue – Get Rid of It. Start Today


Does This Product Work For Crusty Scalp, Hardened Sebum Build Up From Seborrheic Dermatitis, or Dandruff?

We think that this is by far the best product for any type of buildup on the scalp or inside the hair follicles. The buildup is sebum and typically a mixture of yeast, fungus or bacteria. This shampoo has zinc PCA and also herbs that target both. We truly believe it is one of the best if not the best for a healthy scalp from hair root to tip.

3 Ways to Find Gold Nuggets

3 Ways to Find Gold Nuggets
Want create site? Find Free WordPress Themes and plugins.

Even though we have been digging and obtaining gold since at least seven thousand years ago, it still proves to be a notoriously hard task to do. Over time, we went from using primitive tools to metal detectors, and although it made it easier it also, if anything, made it more of a complicated task.

That is because there are now different ways in which you can find gold nuggets. From panning to metal detecting, let’s take a look at some of the best and most popular ways in which people manage to strike a golden win..


Panning for gold is a way that you can extract gold from a placer deposit by using a pan. It is one of the most straightforward and easiest ways to find gold and is probably so common because of the low cost and accessibility.

Gold panning was first done in Ancient Rome, where not just gold but other precious metals got extracted from water streams and mountainsides. 

The process of panning for gold is not very complicated: In the most basic sense, a pan is used with water to filter through dirt. Tiny specks and flakes of gold are part of a water stream, the pan helps separate them from the paydirt.

Start by trying to find a creek or a river and look for the gravel. Check around for dips where the water begins to speed down. Gold paystreaks can accumulate here, and is where you would have the best odds of finding gold nuggets.

In many circumstances, the whole act of panning for gold often just brings up just small amounts of gold dust, which gets collected as a little souvenir in a little glass tube. You can find gold nuggets that are of noteworthy size, but again it is quite hard to.

Metal Detection

A metal detector is one of the newer tactics that is used to find gold. Since there are so many old and neglected gold mines, heading to one of them may be your best bet in finding gold. 

A lot of metal detectors can be expensive, especially the high quality ones of course. So start by scanning around along the outsides of the mine and in nearby areas, then you can choose to make your way in. Remember to follow the rules of your area though, some mines are closed off and it would be considered trespassing for you to enter. It can also be dangerous heading into an abandoned mine.



Many people may not even know what “drywashing” is. Drywashing is when you use a drywasher to find gold in desert conditions:

Vibrations and air pressure is what is used to filter the parts of gold found from gravel and dirt that gets tipped into a drywasher. A basic drywasher can be made with wood, as they have been around for some time.

In hot, arid climates, you can find drywashers being used to sift through loads of material. During the 1940s in New Mexico, it wasn’t uncommon for prospectors to be heading towards sandy areas hoping to make use of the tool. 

Panning and drywashing are almost like polar opposites, and often get compared to one another, but it is good to realize that panning is more of a beginner’s method whereas drywashing is slightly more complicated and requires a bit more commitment.



Searching for gold is a classic and timeless hobby, and people all around the world are still enjoying it today. With all the massive modern machinery, it is fun to just go back to the basics if you are a hobbyist and enjoy panning, detecting and drywashing for gold.

If you manage to have absolutely zero luck, check out Nuggets by Grant – sellers of high-quality Alaskan, Australian and North American gold.

The Internet is full of information about cryptocurrency. Many people take courses and try to learn how to invest correctly to increase their level of income. The situation with digital money literally goes to a new scale and reaches a peak, although it seems that there is no further development. The current boom in cryptocurrency possibilities and the hype surrounding them has provoked many people to try to make money in the new field. Those who realized that buying their own equipment for mining is not a good idea, began to actively study bitcoin hosting and cloud mining. The skeptics say it is an unprofitable and difficult business, while others raise their profits and enjoy life. Let’s get to the bottom of what mining is and how to start mining bitcoin.

What is Cryptocurrency Mining?

Cloud mining is one of the best ways to make money from cryptocurrencies because it frees the user from 24/7 control, high electricity bills and other difficulties of classic mining. It can be used to mine Tron(TRX), Bitcoin(BTC), Ethereum(ETH), as well as other digital money depending on the service. Unlike classic mining, where you have to buy the equipment yourself, cloud mining involves the use of special cloud services that accumulate capacity in their data centers. The idea is to rent the capacity of an existing company, thus avoiding problems with power bills, excessive noise in the apartment, and heat generation.

SVIP  RECHARGE (5000000-99999999) DAILY REVENUE  (12.0%) DAILY WITHDRAWAL (8.0%)


Since there is a rising interest in cryptocurrency mining as the cryptocurrency market matures and gains greater acceptance, cloud mining can be a great alternative to hardware mining. It comes with lower upfront investments and commitments and is considered to be a highly cost-effective option. However, it is important to note that TRON(TRX) or cryptocurrency mining can take months or even years to turn profitable. Having advanced technical expertise is also recommended. While cloud mining or even TRON(TRX) mining may not be for everyone, it is definitely promising and can be immensely rewarding over time. You can visit MAXusdt Official Website for more information.

Are there more wheels or doors in the world? We asked an MIT professor for the answer

Are there more wheels or doors in the world
Want create site? Find Free WordPress Themes and plugins.

Doors or wheels? That is the question: Whether ’tis nobler……

A debate to determine whether there are more wheels or doors in the world has taken the internet by storm. No, really.

The discussion has divided social media users into teams, with one side pointing to hotels, apartment buildings and dorms and the other citing suitcases, bicycles and other common items that function with wheels.

According to the website Know Your Meme, which tracks popular internet memes, the debate started raging when Twitter user Ryan Nixon posted a poll last week asking: “Do you think there are more doors or wheels in the world?”

More than 223,000 people voted in the poll, with wheels beating out doors.

The question quickly spread on social media, with celebrities, journalists and other Twitter users defending their positions on #TeamWheels or #TeamDoors.

“there are more wheels than doors. literally not even a debate. goodbye,” tennis player Coco Gauff shared.

The debate also went viral on TikTok. #TeamDoors pointed to skyscrapers, bathroom stalls, dog doors and refrigerator doors adding up around the world.

But #TeamWheels pointed out that while large office buildings have many doors, they also have desk chairs that often have wheels. Motorcycles and bicycles have two wheels and no doors – the list goes on.

Our favorite memes of 2022 (so far):Elmo vs. Rocco, Wordle scores and ‘Euphoria’ costumes

“There is no Team Wheels and Team Doors. That is a fundamental misunderstanding of this situation we find ourselves in. There is a Team Wheels, and then there is a Team People Who are Mistaken,” author John Green said on TikTok.

Carlo Ratti, a professor at the department of urban studies and planning at MIT, told USA TODAY that although he has not tried to calculate a definite answer, there are “many ways to look at this.”

He said his gut feeling was that there are more doors in the world, pointing to doors inside homes and at offices, restaurants, shops, supermarkets and more.

There Are More Wheels Than Doors In the World

There Are More Wheels Than Doors In the World

Are there more wheels or doors in the world

When New Zealander Ryan Nixon asked Twitter users whether they thought there were more doors or wheels in the world, he probably didn’t expect to start an online war. But that’s exactly what happened after March 5, as social media users, statisticians, and mathematicians all tried to solve this seemingly unsolvable riddle.
Car insurance comparison super app Jerry is here to end the debate. As experts on all things car-related, we know a thing or two about wheels—and we’re here to prove that, yes, there are more wheels than doors in the world.

How many doors are there in the world?

Without getting too deep into the numbers, we can estimate that there are as many as 33 billion doors in the world, between houses, apartment buildings, vehicles, and the cabinets, closets, and other compartments inside them.
That’s a lot of doors! But how does it compare to the number of wheels? Let’s take a look.

How many wheels are there in the world?

Okay, it’s pretty much impossible to give an exact count of all the wheels that exist in the world. After all, we’re making more all the time, and have been ever since the first wheel was invented around 3,500 BCE.
About 152,971 passenger cars were manufactured in 2020 alone (that’s 17 a second!), and even Hot Wheels produces close to 15 cars every second! And that’s not taking into account all of the wheels turned out each day for bicycles, shopping carts, airplanes, office chairs, and non-Hot Wheels toys.
To get a decent estimate of the number of wheels in the world, let’s break down the different types of wheels.


The first car, the three-wheel Benz Patent Motor Car, was invented in 1886—and ever since, wheels have been a part of life.
There are 1.446 billion cars in the world today. Multiply that by four, the average number of wheels on a standard modern passenger car, and you’re looking at 5.784 billion wheels.
“But, wait,” you say (in a smug, anti-wheel voice). “Don’t most cars have the same number of doors and wheels?”
And it’s true: most of the cars manufactured in the world are sedans, four-door SUVs, and other cars with an apparent wheel-to-door ratio of 4:4. For instance, the Toyota Corolla, the best-selling car of all time with 37.5 million units sold, has four doors and four wheels—a wash, right?
Wrong. Most cars have the same number of doors and tires—but wheels are a very different matter. After all, every car has a steering wheel. The gears that run your engine? Those are wheels, too. In fact, your car is full of wheels, big and small, that unquestionably outnumber the doors.
Even if we knock off the four main wheels and limit our count to steering wheels and transmissions, that’s an average of six wheels per car. Do the math, and we’re talking 8.676 billion wheels—more wheels than people, let alone doors for them to walk through!

Toy wheels

Toys are another major source of wheels, from Hot Wheels cars to LEGOs to Tonka trucks, Razor scooters, and that Fisher-Price corn popper toy that toddlers push around.
Hot Wheels alone has sold more than six billion cars, meaning there are roughly 24 billion tiny wheels out there in the world—and these miniatures don’t have working doors, meaning that every one of those wheels stays in the county. Hasbro’s Tonka has sold millions of pint-sized construction vehicles, with over 15 million sales of the iconic yellow Mighty Dump Truck alone. Hello, 60 million more wheels.
We could keep going—but adding up the sales of every single toy car company is a task too gargantuan even for us. Suffice it to say that if the gears-and-steering-wheel argument didn’t convince you, the toy industry produces enough wheels every second to outnumber the world’s doors without a sweat.

Bicycles and motorcycles

Sometimes two wheels are all you need—just ask bicycle and motorcycle enthusiasts!
Bicycles have been around since German inventor Karl von Drais patented the first in 1817, and there are about 1 billion bicycles in the world today. Motorcycles, on the other hand, were invented by Gottlieb Daimler in 1885, and there are just 49 million today.
Between bicycles and motorcycles, we add at least 2 billion wheels—and that’s not taking into account gears!

Other wheels: shopping carts, trailers, and furniture

Between cars, toys, and other wheeled vehicles, it’s already clear that wheels outnumber doors. But if you’re still not convinced, take a look around your home and neighborhood.
Got an office chair in your spare room (thank you, work-from-home)? That’s an average of five wheels. Shopping carts, hand trucks, trailers, and baby strollers all have wheels (and no doors). If you’ve got any furniture in your home with casters, those count as wheels too—and, if we’re getting really technical about it, every single sliding drawer in your home requires at least a couple of wheels to operate.

The bottom line

We’re nowhere near an exact estimate of the total number of wheels in the world, but it doesn’t matter. Already, we’ve identified well over a possible 37 billion wheels in the world—way more than the number of doors.

Which country has the most wheels?

So it’s official: there are more wheels than doors in the world. But which country has the most?
That honor might go to China, which has an estimated 302 million cars alone (not counting other wheel sources). However, itty-bitty San Marino might have the world’s highest concentration of wheels, with 1,263 vehicles per 1,000 people. The country that drives the least, on the other hand, is Bangladesh, with just 4 vehicles per 1,000 people.
In the United States, you’re probably expecting to find the highest concentration of wheels in L.A.—and you’d be close! Car ownership statistics show that nearby Murrieta actually has the highest rate of vehicle ownership of any US city.
The city that drives the least, on the other hand, is (of course) New York City, where the MTA runs all hours of the day to get New Yorkers around the five boroughs. But at the bottom of every New York City subway car, amongst the garbage and the rats, you’ll find eight glorious wheels.

Why it matters

Haters will say that the door vs. wheel debate is a pointless argument, designed to waste time and turn friends against each other. But there may be a deeper truth beneath the madness. Every wheel represents progress, forward motion, and power. If your first answer to the question “are there more doors or wheels” was “wheels, of course,” you may be more tuned in to those elements of life, more open to new experiences, and more driven to explore the world.
Wheels are everywhere—and that’s a beautiful thing.

Investigating the phenomenon of NSFW posts in Reddit
Want create site? Find Free WordPress Themes and plugins.


In this paper, we study the characteristics of NSFW (Not Safe For Work) posts in Reddit, highlighting their differences from SFW (Safe For Work) posts, which have been much more studied in the past literature. In our investigation, we studied all Reddit posts from 2019. Through both descriptive analytics techniques and social network analysis techniques, we extract three findings on the main differences between NSFW and SFW posts in Reddit. Thanks to these findings, we are able to better understand the dynamics (authors, subreddits, readers) behind NSFW posts. In particular, it becomes clear that this is a niche world where authors are strongly cohesive. However, at the same time, the most popular ones show a clear opening to new authors, whom they are willing to collaborate with, from the beginning.


Reddit1 is currently one of the most active social media. It has been extensively studied by researchers in the past [19]. In [25], the authors present an interesting longitudinal analysis of the evolution of this social medium. Furthermore, many papers have focused on specific aspects of this social network, concerning, for example, community structures and interactions [27], [8], [10], user behavior [3], [14], [16], structure and content of subreddits, posts and comments [24], structural properties [10], [13], [33], text classification [15], user migration [21], political and ideological aspects [12], [31].

One aspect of Reddit worth to be analyzed involves NSFW (Not Safe For Work) posts. This term refers to user-submitted content not suitable to be viewed in public or in professional contexts. The phenomenon of NSFW posts in Reddit has been very little investigated, although it is very common in this social medium. In fact, only a very small number of authors have analyzed it [17], [20]. The term “NSFW” has been proposed since 1998, and is one of the oldest acronyms of the Internet. Since its first appearance, many social media, such as Twitter, WhatsApp and Reddit, have adopted it to indicate certain sections or contents. In addition, several authors have focused on the analysis of this phenomenon in other social networks. The study about the role of images and selfies in NSFW content of, presented in [28], and the analysis of the anonymity level of NSFW content in both Twitter and Whisper, described in [7] are two examples.

In this paper, we give a contribution in this setting investigating the phenomenon of NSFW posts in Reddit and describing the whole context (authors, subreddits and readers) behind it. For this purpose, we consider a dataset that includes all the posts published in Reddit from January 1st, 2019 to December 31st, 2019.

During our investigation, we carried out three types of analysis, namely:

Descriptive Analysis, to study the distributions of the entities involved in the phenomenon (e.g., the distribution of NSFW posts against subreddits, authors, score and comments).

Social Network Analysis, to study the co-posting phenomenon, and therefore the interactions between authors of NSFW posts.

Assortativity Analysis, to extend and deepen the previous analyses to discover and study whether possible forms of assortativity [22] exist among the authors of NSFW posts. Recall that assortativity is a particular case of homophily in social networks [18], which indicates the tendency of a node to cooperate with nodes having similar characteristics.

These analyses allowed us to extract three findings regarding NSFW posts, NSFW authors and NSFW subreddits, respectively. Throughout our analysis, in most of the cases, we compare each finding on NSFW posts with the corresponding one on SFW (Safe For Work) posts. Some of the questions these findings provide an answer to are the following:

What can be said about the spread of NSFW posts in the subreddits?

What can be said about the quantity of posts an NSFW author usually submits?

What can be said about the score of NSFW posts?

What can be said about the number and the score of comments to NSFW posts?

What can be said about the level of interconnection between authors of NSFW posts?

Is there a backbone among experienced authors of NSFW posts? In other words, do they tend to interact only with their peers (i.e., authors with the same level of experience), or are they open to collaborations with new authors who have just started publishing NSFW posts?

Finally, we suitably combine the knowledge represented by the three findings in order to describe the dynamics behind the phenomenon of NSFW posts in Reddit.

The rest of this paper is organized as follows: In Section 2, we present related literature. In Section 3, we describe the dataset used in our analysis. In Section 4, we provide an overview of our investigation activity. In Section 5, we study various distributions involving NSFW posts. In Section 6, we study several distributions regarding comments of NSFW posts. In Section 7, we investigate the co-posting activity of the authors of NSFW posts. In Section 8, we evaluate the assortativity of the authors of NSFW posts. In Section 9, we combine the three findings derived during our investigations in order to define an overall picture of this phenomenon. Finally, in Section 10, we draw our conclusions and think of some possible developments of our research efforts.

Section snippets

Related literature

The term “NSFW” was first proposed in 1998 and it is one of the oldest acronyms of the Internet. It refers to content that is not suitable to be viewed in a working environment. Since then, different online systems, like Twitter, WhatsApp, many forums, and Reddit, have adopted this term to label sections with posted content not adequate for everybody and, in general, not suitable for public and professional contexts. Specifically, Reddit has introduced a dedicated group of contents called NSFW

Dataset description

The dataset used for our analysis has been downloaded from the website [1], one of the main Reddit data sources. In particular, we extracted all the posts published on Reddit from January 1st, 2019 to September 1st, 20192. The number of posts available for our analysis was 150,795,895. In Reddit, an NSFW post must be marked as such by its author.

Overview of our investigation activity

Our investigation of the phenomenon of NSFW posts in Reddit follows the workflow shown in Fig. 1.

Due to layout reasons, this figure shows the dataset in input only to the first module. Actually, the dataset is provided in input to each module of the workflow. Similarly, the descriptive (resp., co-posting) knowledge, which are shown as an input for the co-posting (resp., assortativity) analysis module, are also an output of the investigation activity.

As we can see in Fig. 1, the first phase of

Investigating distributions involving NSFW posts

In this section, we present some analyses directly involving NSFW and SFW posts. In particular, we study the distribution of subreddits and authors against posts and the distribution of posts against the scores assigned to them by Reddit users.

Investigating distributions on comments to NSFW posts

In this section, we analyze the comments to NSFW posts investigating their authors, the scores they get and the subreddits they are submitted to.

Investigating co-posting activity of the authors of NSFW posts

The goal of this analysis is to verify whether there is any correlation between the authors of NSFW posts. As usual, we will extract the information of interest and we will compare the behavior of authors of NSFW posts with the ones of SFW posts. In this activity, we will use a support data structure that we call co-posting network. Having observed in all the previous experiments that the results obtained for the Jan-Feb datasets (i.e., D and D‾) are stable, from now on we will refer to these

Evaluating assortativity of the authors of NSFW posts

The concept of “assortativity”, or “assortative mixing”, in a social network points out the predilection of its nodes to be connected with other nodes that are somehow similar to them. This concept, introduced by Newman [22], can be seen as an evolution of the concept of homophily [18], typical of Social Network Analysis. Assortativity is orthogonal to node similarity metrics considered, even if most of the authors in the literature have studied it with respect to node degree. According to this


Combining together all the previous results, we can define three main findings related to posts, authors and subreddits, respectively. Some of these findings are made up of several sub-findings.

The three findings are the following:

PF (Finding on NSFW posts).


NSFW posts are generally published in much fewer subreddits, have much lower scores and are much less commented than SFW posts.


The scores of comments to NSFW posts are much lower than the ones to SFW posts.

AF (Finding on NSFW authors).




In this paper, we have presented an approach to investigate NSFW posts in Reddit. We have seen that this type of content is frequent in this social medium and, despite this, there are very few studies on this subject in the past literature. We have tried to fill this gap and we have proposed an approach that investigates the phenomenon of NSFW posts in Reddit with descriptive, co-posting and assortativity analyses.

In this way, we have obtained three findings, which, together with the principles

The Double-sided “Personality” of Semiconductor Alliance

The Double-sided "Personality" of Semiconductor Alliance
Want create site? Find Free WordPress Themes and plugins.

Alliance can not only be blatantly targeted, but also create the future of the semiconductor industry.


In recent years, semiconductor alliance is gradually gaining momentum, from Chip4 to SIAC, from UCIe alliance to Wi-Fi alliance, alliance members seek new scale, standard or positioning to deal with common competitors or push business to new areas in order to ensure the market advantages of all parties.


With the gradual increase in the number of semiconductor alliances, behind the various alliances, there are not only the promotion of the development of the semiconductor industry, but also some different mysteries.

Let China’s beleaguered Chip 4


In March this year, the US government put forward a new plan codenamed “Chip 4”– proposing the establishment of an alliance composed of the United States, South Korea, Japan, and Taiwan of China. It is widely believed in the industry that if the alliance is reached, the United States will strengthen cooperation with South Korea, Japan and Taiwan around Chinese mainland, and put more pressure on China’s semiconductor ecosystem. As a result, the alliance is also part of US efforts to curb the growth of China’s chip industry, and Chip 4 is also interpreted as another move to crack down on China’s semiconductor industry.


In the view of the United States, if we can unite South Korea, Japan, and Taiwan, we will be able to take the initiative in semiconductor materials, components, chip manufacturing, equipment technology, and other aspects. According to the analysis of people in the industry, if the “Chip Quadripartite Alliance” goes smoothly, China’s Taiwan MediaTek, TSMC, and Sunmoon Light, three leading manufacturers involved in design, manufacturing and closed testing, will certainly be invited; South Korea will be represented by Samsung and SK Hynix; Japan will be dominated by Toshiba, Renesa, Tokyo Weili Kochuang and other enterprises. In the United States, there are heavyweight manufacturers such as Applied Materials, Micron, Intel, Broadcom and Qualcomm, which will form “the strongest alliance in the history of semiconductors.”


In the field of semiconductor equipment and materials, American Applied Materials and Tokyo Electronics of Japan are the world’s semiconductor equipment and materials giants. Applied Materials is the global semiconductor equipment giant. In 2020, Applied Materials continued to top the global semiconductor equipment list published by VLSI Research with revenue of 16.365 billion US dollars. Applied materials are the leaders in the field of ion etching and thin film deposition. Tokyo Electronics, Japan, the company’s products can cover almost all processes in the semiconductor manufacturing process. According to the ranking of global semiconductor manufacturing equipment manufacturers released by VLSI Research, Tokyo Electronics of Japan is the first semiconductor equipment company in Japan and the third in the world. Tokyo Electronics accounts for more than 70% of the market for equipment such as glue coating, development equipment and FPD manufacturing.


In the field of chip design, Samsung Electronics, Intel, Qualcomm and MediaTek occupy the first, second, fifth and seventh positions respectively in the ranking of the top ten semiconductor suppliers by revenue in 2021 published by Gartner, and the design capabilities of these semiconductor giants are also very excellent.


In the field of chip manufacturing, TSMC is the leader. As the most advanced contract factory in the world, TSMC also reiterated that it is expected to put 3nm process technology into mass production in the second half of 2022. The foundry also plans to put the enhanced N3E of N3 into mass production in the second half of 2023.


In the field of chip closed testing, Sun and Moon is the world’s largest provider of chip packaging and testing services.


The above enterprises have a pivotal position in each link of the semiconductor industry chain, the giant is United, and the industrial chain has a far-reaching impact.


After a lot of trouble, what on earth is the pursuit and interception of the United States?


From the perspective of China’s development, in recent years, China’s semiconductor industry has developed rapidly, driven by multiple factors, the market scale is growing year by year, the overall strength of the industry is increasing rapidly, the industrial structure is constantly optimized, and the degree of industrial regional aggregation is also increasing. Chinese mainland has also maintained strong growth in building its semiconductor manufacturing supply chain, announcing 28 new fab construction projects in 2021 with a total planned funding of US $26 billion.


The United States feels threatened and is curbing the rapid growth of China’s semiconductor industry in all directions.


From the perspective of the United States, the US semiconductor industry maintains a leading market share in R & D-intensive areas such as EDA and core IP, chip design and manufacturing equipment, but manufacturing is the weakness of the United States. According to estimates by the American Semiconductor Industry Alliance (SIA), the share of modern semiconductor manufacturing capacity in the United States has fallen from 37% in 1990 to 12% in 2021, mainly because other governments have invested a lot in chip manufacturing incentives, while the US government has relocated manufacturing to Southeast Asia because of environmental pollution and labor returns. Therefore, the United States wants to implement relevant incentives to ensure the competitiveness of American semiconductor manufacturing.

Can Chip 4 fulfill America’s ambitions?


For allied enterprises, joining Chip 4 may make them lose the Chinese market. Global chip sales reached a record $555.9 billion in 2021, and Chinese mainland remains the world’s largest semiconductor market, with sales totaling $192.5 billion in 2021, according to SIA.


According to South Korean media, the South Korean government has not yet expressed its position on this, because South Korean semiconductor companies have key production facilities in Chinese mainland, Samsung Electronics and SK Hynix have factories in China, and their products account for an important share of the global market. Samsung Electronics’ only overseas memory chip factory is located in Xi’an. Its NAND plant has a monthly capacity of 265000 12-inch wafers, accounting for 42 per cent of Samsung’s total NAND flash memory production. SK Hynix produces DRAM chips in Wuxi, accounting for 47 per cent of the company’s total DRAM chip production.


Taiwan manufacturers also privately revealed that it is quite difficult to set up Chip 4, coupled with the fact that there are many competitive relationships among relevant semiconductor enterprises, and it is not easy to form a close alliance, and the main feasible model may be to curb the development of the mainland semiconductor industry from equipment and EDA tools.


For the United States, if Chip 4 is formally established, it will be able to curb the development of China’s semiconductor industry. Chinese semiconductors are highly dependent on foreign technology and equipment. Once Chip 4 plays a role, China will be besieged on all sides in the entire semiconductor industry, from chip design to chip manufacturing, from chip raw materials to chip equipment, giant blockade makes China lose more development opportunities.


Before Chip 4, SIAC also had a potential impact on China’s semiconductor industry


On May 11, 2021, the American Semiconductor Alliance (SIAC) officially announced its establishment. The alliance consists of semiconductor design and manufacturing enterprises, as well as downstream customers in the industry who use semiconductors heavily in consumer, military and other important areas of products. According to the description of the official website of SIAC, SIAC is a cross-industry alliance formed by enterprises that manufacture and use semiconductors. Its main mission is to advocate and call for the introduction and implementation of relevant policies on semiconductor manufacturing in the United States in the form of an industry alliance, so as to promote the continuous innovation and development of semiconductor technology in the United States, so as to support the upgrading of the future economy, critical infrastructure and defense equipment of the United States. The sudden establishment of the American Semiconductor Alliance will not only bring changes to the supply chain of the American semiconductor industry and the global semiconductor industry, but also have a potential impact on the development of China’s semiconductor industry.


On the face of it, SIAC is a business alliance, but there are no Chinese companies in this alliance. Judging from the US policy toward China in the past, the establishment of this alliance is not good news. The United States not only blocks science and technology against China, but also intends to put China out of the semiconductor industry chain and speed up the technological iteration of the chip industry. to widen the gap with China.


On the back of “containment”, new technologies are born from industrial alliances


Not all alliances are so anti-globalized. Contrary to the encirclement and interception of Chip 4 and SIAC, the spontaneous alliances of the industry provide a hotbed for the growth of new technologies.


UCIe Alliance Reconfigurable Chip Interconnection Standard


The UCIe (Universal Chiplet Interconnect Express) alliance, which includes Intel, TSMC, Samsung, AMD, Arm, Qualcomm, Sunlight, Google Cloud, Meta, Microsoft and other industry giants, aims to establish a unified die-to-die (bare film to naked film) interconnection standard and create an open Chiplet ecosystem.


As an important way to continue Moore’s Law, due to the use of advanced packaging technology based on heterogeneous integration, Chiplet makes the production of complex chips no longer constrained by different processes, improves the overall performance by means of computing power expansion, and greatly shortens the production cycle. But like all technologies, Chiplet also faces many challenges. Packaging small chips with different specifications and characteristics together, heat dissipation, stress and signal transmission are all major tests. The biggest problem is that the standards are not unified, and it is difficult to match and combine the Chiplet developed by different manufacturers, thus limiting the development of the whole format.


Unified connectivity standards are therefore critical. UCIe breaks the boundaries between different processes and fabs, and the best way to achieve standardized hardware across multiple vendors is to set a single open specification that everyone can use.

In early April, domestic core original shares announced to formally join the UCIe industry alliance. As one of the first enterprises for Chinese mainland to join the organization, Xinyuan, together with other members of UCIe Industry Alliance, will work together on the research and application of UCIe1.0 version specifications and new generation UCIe technical standards, so as to further lay a solid foundation for the development of Chiplet technology and products.


WiFi Alliance, always on the way



Similar in nature to the UCIe alliance, the WiFi alliance, which has been established for more than 20 years, has been on its way. In 1999, six technology companies established the Wireless Ethernet compatibility Alliance. In 2000, the name was changed to Wi-Fi Alliance, and the term “Wi-Fi” was introduced, and the Wi-Fi CERTIFIED certification program was released. Over the years, Wi-Fi has significantly improved lives and the way individual institutions operate, which used to be a technological start. The Wi-Fi Alliance’s blueprint includes a number of key factors that will facilitate the widespread use of the organization’s technology in new market segments and applications. By maintaining ideological leadership, promoting the use of spectrum and industry cooperation, Wi-Fi Alliance has promoted the global adoption and development of Wi-Fi.




Among the various “alliances”, some are to suppress certain countries, while others lead the industry to develop and adopt agreed standards in the industry, promote efficient global cooperation among member companies, embrace technology and promote innovation. The industry is well aware of which plays an important role in the industry.

Since the birth of technology, the pace of inventions and innovations has continued to accelerate. New inventions and technologies make our lives easier, but interestingly, technology often leads to new ideas and discoveries, making it easier to design and build even new technologies. This rapidly evolving cycle of innovation continues to reshape and redesign the world we live in.

The issue of electric vehicle technology has not been resolved, following this innovative process over the past 200 years. Looking back on the invention of the first electric motor in 1832, it is hard to imagine the impact that electric motors have already had on our lives and other technologies, and it is even harder to imagine the next 200 years of reconstruction. By recounting the history of the electric engine, we will see a faster cycle of innovation in live action and better understand what to expect in the future.

First Electric Motor

Hans Christian Orsted was examining electricity in 1820, when he noticed that the compass was tilted away while holding an electric pole near it. He had just discovered electromagnetism and although no doubt he did not understand the impact of his discovery, he simply put the ball forward to develop the technology of electric vehicles.

Observation of the deflection of a compass needle by Hans Christian

History is made when Thomas Davenport of Vermont invented the first official battery-powered electric motor in 1834. This was the first electric motor that had enough power to perform a specific task and was developed to power a small printing press. Various Davenport motors were able to run a model trolley on a circular track and other functions. In time, the trolley became the first electric power car.

Invention of the DC Motor

William Sturgeon invented the first DC engine that could provide enough power to drive machinery, but it was not until 1886 that the first DC engine was produced that could run at a steady pace under changing load. Frank Julian Sprague was its founder, and it was this motor that gave the impetus to the widespread adoption of electric motors in industrial use.

Frank Julian’s DC motor

Sprague’s electric motor removes sparks, loses power from all windings, and can deliver power at constant speeds – making it the first ‘active’ DC car, allowing for widespread use of electric motors. Sprague’s car designs were reliable and powerful, but the efficiency of these designs left much to be desired. Sprague was to use his engines to develop the first electric car system the following year  in Richmond, Virginia in 1887.

AC Induction Motor

Despite the great discovery of Davenport many years earlier, electric motors were not widely used at commercial level for another 50 years. Scientists and engineers continue to develop various types of electric motors with the aim of making them ideal for commercial use. Soon, electric motors began to be used in all industries, factories, and homes.

In 1887, Nikola Tesla made it into the halls of electric motor history when he invented the AC induction engine which he successfully patented a year later.

It was not suitable for road vehicles but was later replaced by Westinghouse engineers. In 1892 the first active induction engine was developed, followed by a rotating bar rotation, making the unit suitable for use in automotive systems.

Development of Three-Phase Motor

In 1891, General Electric started making three-phase induction motors to make motors more reliable and efficient. In order to use the bar-winding rotor design, GE and Westinghouse signed a separate license agreement in 1896.

Modern Electric Motors

In 1921, a new design concept for electric motors was introduced and increased its reliability and efficiency. Although a car maintenance team was launched in the United States to prevent damage caused by friction between parts, a small air gap between the rotor and the stator has also been found to facilitate the flow of electromagnetic flux into DC machines, further increasing its efficiency.

In the 21st century, AC and DC electric motors are now widely used in industry around the world and are an integral part of many applications.

From electric wheelchairs and stairlifts to industrial automation, flexible transport, and solar panels. Electric motors have revolutionized the whole world through its applications in everyday life.
