Keep Your Skin Radiant and Healthy with Fruits and Vegetables

I’m sure you have your own favorite face cream that you are regularly using to keep your skin toned. But to have beautiful skin, you should start with nourishment from within. The cells are constantly changing: the old ones are shedding and the younger ones are replacing them. To support this constant and rapid growth, you need to keep a steady supply of essential nutrients. When you keep a correct balance of foods in your diet, you feed to your skin the vital nutrients that it requires in order to stay soft, blemish-free and supple.

All these essential nutrients you can get from the fruits and vegetables. First of all from them you get the powerful antioxidants, which you need to protect your skin from the cellular damage that can be caused by the free radicals. These free radicals can cause your skin to wrinkle and become dry. Secondly, from fruits and vegetables you get the so important vitamin C. It helps you to maintain a strong immune system, gives you a radiant skin and keeps the blemishes away.

Eating fruit and vegetables in abundance is the most effective way to healthy skin and a sexy shade of skin, according to the conclusions reached by a team of researchers.

In countries like the UK, most people think that the best way to have a more attractive skin tone is tan in the sun or under UV lamps, but research conducted by Dr. Ian’s team Stephen (University of Bristol) shows that eating plenty of fruit and vegetables is actually more effective.

The team, which has conducted his research at the Perception Laboratory at the University of St Andrews, Scotland, first assessed the tone of the skin of Caucasians in relation to their diet. Those who ate more servings of fruit and vegetables per day were also having a golden skin tone.

Further analysis using a spectrophotometer measured the way in which the skin absorbs the light from different parts of the spectrum, revealing that the fur of a golden hue had greater presence of carotenoids, antioxidants that are red and yellow, to which attributed a major influence in the immune system and fertility. Generally, carotenoids are found in fruits and vegetables.

In the second part of the study, the team used specialized software to manipulate the skin tone in images of 51 faces/ This was done in order to simulate the presence of more or less carotenoids and more or less tan. Participants were then asked to adjust the hue of the skin to make the female face look as healthy as possible. By giving a choice of improved skin color by tanning or improved by the carotenoids, the participants preferred the color modified by carotenoids.

This study shows that people can use not only tracks on the pitch to judge how safe are other individuals, but we are also capable of great accuracy when we make those assessments. This ability makes sense in the context of human evolution, because they tend to favor individuals who choose to form alliances, or mate, with healthier individuals, and penalize those who do with people in poor health.

How to Choose the Best Water Softener For Your Home?

One of the top necessities for all the human beings is water. However, it is essential that we use water that is clean and safe. One of the water issues that carry an impact not only for our health, but also for the life of our home appliances and plumbing is hard water. An appliance that helps to solve this issue is a water softener. It’s a system that works through a chemical process and makes the hard water soft. But how do you determine the right type of water softener for your home? Read below for advice.

The water is considered to be hard if it contains a high level of minerals. The minerals that make it hard are calcium and magnesium. First thing you should do before starting to look for a water softener is determine if you do have hard water and what is its level.

One simple way to see if you have hard water problems in your home is with the use of a bottle and some liquid soap. Shake up a half-filled water bottle and then spill it out. Fill it again half way with water and also add 5-6 drops of any liquid soap, can be dish washing soap. Screw on the cap and give the bottle a second round of shaking it up. After a good shake, remove the cap. If you see the bottle full of foam and it’s overflowing through the cap, your water does not have hardness issues. On the other hand, if all you see is soapy film, the water is hard.
An alternative option for testing water hardness is with the help of a test kit. They usually use strips and can tell you both if the water is hard and its level.

After determining that the water you use is actually hard, the next step is calculating the capacity of water usage in your home. The average water usage is 80 gallons per person. So multiply your household members by 80 and you will have the number of gallons you consume daily.

how water softeners work

The next calculation involves the hardness level of the water. This will help you to understand the needed capacity of the water softening system. It’s usually measured in grains that need to be removed. You can find out the amount
of hardness using a special test kit or take the average number, which is 10 grains per gallon. So for the final calculation you need to multiply 10 by the total number of gallons that you daily consume. The result is the total amount of grains that you will need for the water softener to filter. According to this number you will need to look for a water softener with the right capacity. Knowing the capacity, start looking for different types of water softening systems.

Main Types of Water Softening Systems

Timer regenerated:
These units are equipped with a timer that you can set for regeneration after each particular period of time based on your daily water usage. Most of these systems usually use salt or potassium chloride for the regeneration and for each process it uses about 8 pounds of salt. Meter regenerated. The system of these units first analyzes your household’s water usage and then adjusts the regeneration to fit it. This option is more
efficient compared to the previous system. It regenerates only when needed. Thus saving water waste and salt usage. It’s the most popular choice among buyers.

Manually regenerated:
These units come without a timer or meter. The regeneration is activated using a simple level. So you regenerate the water softener only when you want to. It’s a good option for those that don’t have a
drain where they could place the water softener. In this case, when regenerating, you will need to attach a garden hose and find a drain.

Brain-Controlled Device for Paralyzed People

I’m sure anyone would think that it would be fun to be able to move objects with just your mind. However, for millions of people who live with paralysis, the implications go deeper. It would be a huge step forward for them to a more independent living, if they could mentally control artificial limbs and have mobility devices. The director of the BrainLab at the Georgia Institute of Technology, Melody Moore Jackson, has started the lab in 1998 in an effort to try to make this happen.

In her lab Jackson was researching methods of brain control, particularly the ones that didn’t involve surgery. At the time when she started her lab, there were only five similar labs that were conducting the same research. Now, there are over 300. However, the BrainLab was among the first that demonstrated you can use brain signals of the person to control a wheelchair and a robotic arm.

According to Jackson’s words they can influence the wiring of the brain, which would allow the person to make new neural connections, and possibly restore movement of a paralyzed arm.

Except the paralyzed people, also patients with locked-in syndrome could benefit from such technologies. Locked-in syndrome is a rare neurological disorder. The patients that have it usually feel, think and can understand language, but they are not able to speak or move. As Jackson explains it, they are “prisoners in their own bodies”.

In recent years there has been a lot of research in developing a brain-computer interface that would help such people.

Another research group, which has also become a pioneer in this area, is the Miguel Nicolelis’ laboratory at Duke University Center for Neuroengineering. They have shown that a rhesus monkey that was located in North Carolina could, with the use of only its brain, control the moving patterns of a robot in Japan. In the year 2011, they achieved getting a monkey to send movements to a virtual arm and also feel sensations coming from it.

This team has become the leader of the Walk Again Project, which is an international consortium of research centers that have dedicated their work to the development and creation of the brain-computer interface that could help the paralyzed restore movement.

One of the techniques that Jackson and her team have come up to harness brain signals is given the name of functional near-infrared spectroscopy. This method involves shining a light into the brain in order to discern the amount of activity there and at the same time examining the corresponding oxygen level.

The shining light has a specific wavelength beaming into the brain. The oxygen that is present in the brain absorbs some of that light. With this method the scientists can see the small differences happening in the oxygenation.

As an example, the scientists place a sensor to the Brocca’s area, the part that is essential for language. When you talk inside your head or when you count silently, meaning perform subvocal speech, you activate this area.

The research group has learned that by using the associated oxygen levels, you can create a system that would allow the person to create words yes and no with just thoughts. This technique was initially implemented in the Hitachi device that was used by patients with locked-in syndrome for saying yes and no.
