Science and engineering applications such as control of high-precision motion systems or electrochemical processes are often built on mathematical models of dynamic systems. Ph.D. candidate Dhruv Khandelwal developed a framework that allows people without experience in data-driven modeling to fairly easily develop high-quality, optimized mathematical models of these dynamic systems. This is a vital tool that can help researchers of any stripe navigate the complex maze of modeling technologies and systems dynamics, and support data-driven research output and valorization. For instance, electrical engineers managing the health of the electricity grid or researchers studying the growth of cancer cells. Khandelwal defends his Ph.D. thesis on March 4.

E-cigarette vapour is much less harmful to lung cells than cigarette smoke. Lab tests show that, unlike tobacco smoke, which causes oxidative stress and cell death, e-cigarette vapour does not. Oxidative stress and cell death are driving factors in the development of many smoking-related diseases such as COPD and lung cancer.
Vapour from e-cigarettes has been found to contain significantly lower levels of the toxicants found in cigarette smoke (Chemical Research in Toxicology DOI: 10.1021/acs.chemrestox.6b00188), but suitable lab tests and clinical studies are necessary to understand whether this translates into reductions in biological responses and disease.
Researchers at British American Tobacco have developed a standardized way of measuring and comparing the potential of conventional cigarette smoke and e-cigarette vapour to cause oxidative stress in an in vitro model of lung epithelium.

Just imagine a pill you can take to enhance your points of view, increase your memory, and make you more productive. In it sounds like an ultimate life hack, you’re not the only one.
There are pills that guarantee that out there, yet how they work is a little complicated.
These pills are known as nootropics or smart drugs.
So what are nootropics?
Nootropics are a class of brain power enhancing supplements that are utilized to enhance focus and help to boost memory. Nootropics are regularly used to increase capacity to focus, help people concentrate more and reduce anxiety.
You will often observe Nootropics called as “smart drugs” as they are connected with increased intelligence, focus and motivation.
Be they are not at all like brilliant medications which can frequently bring about negative reactions or side effects with long term use. Nootropics are safe to use and pose a low risk of any side effects if used properly.
Numerous nootropics have similar systems of working by improving communication between neurons in your brain, adjusting neurotransmitter levels or by balancing brain cell health.
They also improve metabolism of your neurons, support neuroplasticity, or even support the development of new neurons and neurotransmitters.
How Nootropics work?
There are various sorts of Nootropic supplements accessible. Also, there are distinctive classifications and “families” of Nootropics, for example, Racetams and Ampakines.
Each of these particular supplements work in different ways and have different working mechanism. Given this, there is not one answer to the question “How Do Nootropics Work?” rather a wide range of answers.
There are however some basic ways in which nootropics work and modulate the neutrons in your brain. One of them is listed below
Together, the neurotransmitters and the receptors make up a “framework.” There are an immense huge number of these neuronal frameworks inside the mind.
What a Nootropic supplement does, generally, is to explicitly target and increase the proficiency of those frameworks which result in enhanced cognitive abilities.
How Nootropics will make you a better entrepreneur?
The initial step for an entrepreneur is to investigate what they are doing battling against. For some (myself included) it is to enhance focus and effectiveness during the working hours was my primary objective.
Diehard business people working 18-hour days require to last longer during the day and work normally when sleep deprived.
This is where nootropic role come into play. Below are the benefits of nootropics that will help you to become a better entrepreneur.
1. Increase concentration
Before you consider enhancing your memory capacities, you should first increase your concentration. Nootropics can help with that, particularly in case you can’t concentrate on a particular work over a longer period of time. This is a noteworthy issue with entrepreneurs who encounter inconvenience in concentrating for longer hours of work.
2. Enhances memory
It is easy to read and comprehend a specific topic but the vast majority discover it somewhat troublesome to recover data from their memory. Nootropics have appeared to have beneficial outcome on a man’s memory.
It enhances and repairs all parts of your memory capacities, including the working memory and recall. It additionally supports brain cell development and enhances the connections between the neurons. Aside from these advantages, they additionally repair the neuron, which thusly gives a help in comprehension of data information and recalling it.
3. Improves brain health
With busy schedule and poor diet, out brain takes a genuine bashing. Nootropics not only enhance your memory and information investigation but also improves the overall health of brain. They increases oxygen stream to the brain and maintains neurons and brain cells which keeps the brainwaves casual and more effective.
4. Better mood
The primary reason behind why many individuals can’t concentrate and focus at a specific task is foul mood. A few studies demonstrate that improper eating habits and sleeping habits can affect your mood. Nootropics can boost and stimulate mood enhancing neuroreceptors which makes your mood better and helps you to concentrate more.
Conclusion
Being an entrepreneur is not an easy job. You have to think outside the box that will make your business grow. Nootropics can help you to concentrate more and help you make your product awesome. If with a single nootropic you do not see significant results, you can combine different nootropics to see greater results. This is known as nootropic stacks.

Jock itch. It’s not a welcome visitor for any guy. Even when a dude is really cautious and careful about his penis health, doing everything he can to avoid an itchy penis, he might still end up with a lousy case of jock itch. And while guys all know about the itchiness and discomfort that come with this condition, not all are aware that jock itch also has the potential to affect a guy’s sex drive – and not in a positive way either.
What it is
Known among the medical community by the name tinea cruris, jock itch is a common fungal infection that affects areas of the body covered by or in close proximity to, the area where an athletic supporter is commonly worn. In other words, the penis, balls, inner thighs and buttocks are the most common sites to be afflicted by jock itch.
It presents as a red, itchy rash; frequently the rash is ring-shaped and raised around the circumference. Often it is redder on the edges and a lighter red on the interior of the ring. Sometimes the ring will have a half-moon shape rather than being round.
Fortunately, jock itch is not serious; however, it can bring forth an itchy penis that is extremely annoying. In some cases, a man can scratch the itch so ferociously that the area can become infected.
Jock itch is highly contagious and caused by the same fungus that causes athlete’s foot. So, for example, a man may get it from sharing a towel or clothing of a man with the fungus (either in the form of jock itch or athlete’s foot).
The sex drive connection
A man with jock itch may find that it has a negative effect on his sex drive. Often the reason for this is psychological. When a man has an itchy penis or scrotal area that sports examples of tinea cruris, it may deter any potential partners from engaging with him. It may also make a man feel self-conscious and worried that his formerly glorious penis has become diseased-looking and unattractive. This can in turn make him feel unappealing, a sentiment that may stay with him even after visible signs of the condition have disappeared. His sex drive may suffer as a result.
However, sometimes the decrease in sex drive may be due to the treatment employed to rid himself of his jock itch.
Many doctors recommend the use antifungal powders or creams as a means of treatment. These are often very effective. But at least two common antifungal medications – clotrimazole and ketoconazole, which are found in many medications – can be lower sex drive culprits.
Why? Although large scale studies have not been conducted, animal studies do indicate that use of these ingredients in males can lower testosterone levels. Testosterone is created mostly in the testicles and plays a significant role in bone density, muscle development, fat distribution and, of course, sex drive. Essentially, the more testosterone a man produces, the heartier his sexual appetite.
Fortunately, the effects of these medications on testosterone are temporary; after discontinuation of the treatment, a man should see his sex drive return to normal – and, of course, not all men will see an appreciable difference.
Treating jock itch is crucial, even if the sex drive is temporarily affected. The itchiness associated with jock itch is often alleviated through the use of a superior penis health crème (health professionals recommend Man1 Man Oil, which is clinically proven mild and safe for skin) with a combination of a high-end emollient (such as Shea butter) and a natural hydrator (such as vitamin E). These two ingredients hydrate the skin and create a moisture lock which helps reduce common itching. Keeping the penis skin healthy through the use of a powerful antioxidant is also advised. A crème with the antioxidant alpha lipoic acid is well poised to fight the free radicals that cause oxidative stress in penis skin cells.
