Joma Kleen From OutwitTrade Reviews 2 New Hosting Services

Joma Kleen is a writer for OutwitTrade.com who has extensive experience with WordPress and SEO. Today, he just published two new reviews of hosting companies he has personal experience with, Seek A Host and Bulk Buy Hosting. These are two relatively unknown hosting companies with a very specific use case: each of them are marketed towards SEO experts as so-called “PBN” hosters. A PBN, or Private Blog Network, is a blackhat SEO technique to increase links to a website, and in order to make PBN’s work, the consensus is that it is necessary to have websites hosted on different servers. Seek A Host and Bulk Buy Hosting are services that have sprung up to serve this need.

Joma’s verdict? Both are great services, but they differ mainly in terms of their interface (Bulk Buy Hosting is better than Seek A Host in this respect) and their cost (Seek A Host is much cheaper than Bulk Buy Hosting). For those looking for PBN hosting, Joma recommends trying both of them.

You can read Joma’s Bulk Buy Hosting review and Seek A Host review at OutwitTrade.com.

Regarding “PBN’s”, we recommend reading this post by Neil Patel:

Sleep fragmenting linked to the risk of migraine headaches

Non-continuous sleep, understood as fragmented sleep, can be linked to an increased risk of migraines unlike the duration of sleep itself and the low quality of general sleep. This was achieved by a group of researchers at Brigham and Women’s Hospital and Beth Israel Deaconess Medical Center who published their study on Neurology.

The relationship between sleep and migraine, despite all previous studies, has never been fully understood. The researchers tried to fill this gap by conducting a prospective cohort study on 98 adults with episodic migraine characterized by less than 15 days a month with headaches. Survey participants had to complete electronic journals twice a day recording various details and information related to sleep, headaches and general health habits for six weeks.

In addition, other data came from a wrist device that more objectively captured their sleep patterns. The researchers also considered other factors that could trigger migraine headaches including daily caffeine intake, alcohol intake, physical activity levels, stress and others.

Eventually, the researchers found that the length of sleep, even for people who slept less than 6.5 hours a night, and the poor quality of sleep were not related to migraine the next day or even the day after. What seemed to be related to the increased risk of migraine was the fragmentation of sleep, regularly measured by researchers not only through the diaries compiled by participants but also through the wrist device.

Suzanne Bertisch, an experienced researcher in sleep and circadian disorders at the Brigham and author of the article, explains the results as follows: “Sleep is multidimensional and when we looked at some aspects of sleep, we found that low sleep efficiency, which is the amount of time you are awake in bed when you are trying to sleep, was associated with migraines not the next day, but the day after. However, we have not observed a relationship between the short duration of sleep at night (less than 6.5 hours) or the quality of sleep and the risk of migraines.”

The acidification of the sea off California is twice as fast as the global level

The waters off California are showing a level of acidification twice as fast as the global ocean average. NOAA researchers have obtained this result by analyzing the small microscopic shells found in these areas, shells, and remains of microscopic animals called foraminifers.

They took about 2000 samples of these remains off the coast of Santa Barbara measuring how they have changed over the last 100 years. These shells, in fact, belong to small dead animals and fall to the ocean floor practically every day and are then immediately covered with sediment. The sediment layers themselves therefore represent a sort of vertical recording of climate and environmental changes, including the same level of water acidification.

Looking back in time and measuring the changes in shell thickness, the researchers have obtained an estimate, which they themselves define as “very accurate,” of the level of acidity in this marine area, as explained by Emily Osborne, a scientist who is working in the context of the Ocean Acidification Program and who describes this new technique in a statement that appeared on the site of NOAA itself.

This fossil documentation has shown a sort of cyclical pattern: although the increase in the acidity level of this marine area is quite clear from 1895 to the present day, there have been ten-year changes that have seen a rise or fall in the acidity level itself. According to researchers, these patterns are linked to the Pacific Decadal Oscillation (PDO), a marine phenomenon that sees cooling and warming cycles. This phenomenon can guide and influence the acidification levels of the sea as, among other things, man can do with his carbon dioxide emissions.

“During the cold phases of the Pacific’s decadal oscillation, stronger winds across the ocean push upward the carbon dioxide rich waters to the surface along the west coast of the United States,” Osborne explains. “It’s like a double hammer that increases ocean acidification in this region of the world.”

Planets in habitable areas may not be suitable for life due to stellar radiation

Even if a planet is in the so-called “habitable zone,” it is not said that it can boast ideal conditions and not even sufficient for the existence of life because the star around which it revolves can “flood” it with periodic deadly radiation. What was a strong suspicion of astronomers and exobiologists was confirmed by a new study that appeared in Monthly Notices of the Royal Astronomical Society and conducted by Dimitra Atri, a scientist from the Center for Space Science Research at New York University.

The researcher confirmed, in his study, that planets can be subject and in general very sensitive to the so-called “flare,” real radiation explosions coming from the star that can put an end to practically any form of life (except perhaps to those that are used to frequent only underground). The only way for life to thrive even in the face of such radiation explosions is a sufficiently dense atmosphere or a good magnetic field, something that the Earth can boast of but which increasingly seem to be characteristics not typical of planets.

The researcher used data from 70 major radiation emission events from stars observed between 1956 and 2012. He then simulated on the computer the interaction of these “flares” with various types of exoplanetary atmospheres. The researcher came to the conclusion that these flares can massively increase the level of radiation on the planet’s surface interrupting the potentially inhabitable conditions and thus interfering with the possible existence of life itself.

The same simulation confirmed that atmospheric density and a possible magnetic field are the two main factors that can protect the planets’ surfaces from these violent jets of radiation. “As we continue to explore the planets of the solar system and beyond, finding out if these planets have the capacity to sustain life continues to be of immense importance,” reports Atri himself.

Urbanisation increases aerosol on Amazonian rainforests with negative consequences

A new study warns about the link between urbanization and the climate of the Amazon rainforest, considered as the lung of the planet. The study, published in Nature Communications, shows that urban pollution from Manaus, the populous city in the state of Amazonas, Brazil, causes a sharp increase in aerosol formation in the nearby rainforest and this increase would be higher than previously estimated.

The increase in aerosols, estimated at 60% by scientists of the Fundação de Amparo à Pesquisa do Estado de São Paulo, causes more clouds and rain and changes the levels of photosynthesis of plants. According to the researchers, these results “will make meteorological models more accurate and refine regional and global climate modeling.”

The aerosol is composed of countless tiny solid particles or liquid droplets suspended in the air. It is also naturally present because it is produced by forests (for example, it comes from the formation of pollen, ash or carbon particles from fires), but the “artificial” one is formed by the chemical reactions of the “natural” aerosol with volatile organic compounds (VOCs) or gaseous ones produced by human activities, primarily by the combustion of fossil fuels.

These reactions have a significant effect on the environment: a greater quantity of aerosols in the air means greater absorption of solar radiation and, among other things, a greater quantity of rain.

As Henrique Barbosa, one of the authors of the article, points out, “when levels of sulfur and nitrogen compounds from urban pollution accumulate in the atmosphere, biogenic vapors in the forest oxidize much more rapidly, forming many new aerosols – much more than they would if the process were purely natural.”

First eruption detected in a star 450 light-years away

A powerful star eruption has been identified in the atmosphere of the active star HR 9024, also known as OU Andromedae, a giant star with a high X-ray brightness that causes a giant plasma bubble around the surface of the star itself. The star is about 450 light-years away from us.

This is the first direct observation of a coronal mass ejection (CME), a phenomenon that until now had only been observed directly on our sun. During this blasting, very hot material was ejected with a speed of between 362,000 and one and a half million miles per hour.

The study, published in Nature Astronomy, describes how the astronomers of the National Institute of Astrophysics in Italy have collected and analyzed the data of the Chandra X-ray Observatory, a NASA space telescope.

Explaining the mode of data analysis is the researcher Costanza Argiroffi of the University of Palermo: “The technique we used is based on monitoring the speed of plasma during a stellar blast. This is because, in analogy with the solar case, it is expected that, during a blast, the plasmas confined in the coronal arc where the blast occurs move first upwards, and then towards the lower layers of the stellar atmosphere. In addition, it is also expected to observe a further motion, always directed upwards, due to the CME associated with the blasting.”

The study is important because it shows for the first time that coronal mass ejections can be considered as common events also in other stars, at least in those magnetically active. Moreover, the data confirm the previous theories related to this type of stellar phenomenon.
