Men's sexual ability is a symbol of men's success. How can a man be as good as a person in a sexual life? How can he improve his sexual abilities and develop a man's vigor? Many male friends choose dietary therapy. why?
Is a drug three-point poison "Smart men do not want to use aphrodisiac to rejuvenate themselves. Unless the situation is strong, or young people want to try fresh. Like Viagra, male treasure, Yougui pills, Yishenling particles (Capsules) are all drugs containing sex hormones, which cause male endocrine disorders in certain cases, and aggravate sexual dysfunction, but is it really deceptive to say that aphrodisiac foods are really effective now? Some aphrodisiac foods do have "deceptive" ingredients.
Scientists from the United States have found that foods that are now considered to be aphrodisiac are not all have aphrodisiac effects. Experiments have shown that some common food effects are doubtful.
Through the scientific research, there are apparently five types of aphrodisiac foods. In fact, there are no aphrodisiac effects. There are misunderstandings about the aphrodisiac effects of these foods.
Misconception 1: Spices refreshing.
Many spices from Asia are believed to provoke libido. However, Dr. Alan Herssey, Ph.D., of the Chicago Aroma and Taste Therapy Research Foundation, noted that after the use of perfume, there was no significant change in the degree of congestion between the penis and the vagina.
Misconception 2: Peppers are shaped and shaped.
Many people in India and South America believe that the appearance of pepper is similar to that of male genitalia. The taste is pungent, just like the love of the fire. In fact, the substances contained in peppers are only antioxidant, promote metabolism, and relieve pain, and have nothing to do with impotence.
Misconception 3: Truffle is the "taste of love."
Ancient Greeks and Romans were convinced that truffle had a positive effect. This view influenced many modern Europeans. However, according to the American truffle researcher James Trepp, the musk contained in truffle can only promote the pig's estrus. There is no evidence that it is effective for people.
Misconception 4: Chocolate mentions "sex" fun.
Maybe it's Valentine's Day, people are used to connecting chocolate with love. However, in the study of psychologists and sexual health experts Linda Daweiler, the main ingredient of chocolate is cocoa, which can resist oxidation and lower blood pressure, but it can never make people brave overnight.
Misconception 5: Oysters are aphrodisiacs.
Oysters are aphrodisiac food advocated by European and American people. According to surveys, 25% of people think that it has aphrodisiac effect. Joey-Davidson, the psychologist and author of "The Fearless Sex," believes that the extraordinary shape of oysters is often compared to female genitalia, and from a psychological point of view, it may stimulate male libido. However, from a nutritional point of view, oysters contain a large amount of minerals and trace elements of zinc, can only help improve the system of immunity, enhance sexual desire is absolutely impossible.
Did you know these arguments from scientists? If you don't eat these foods, why do you not eat these foods? Experts at Guangzhou Men's Hospital said that although these foods do not have aphrodisiac effects, there are also proteins, trace elements, and other substances that the body needs.
Everything You Need To Know About LED Lighting
LEDs are a simple invention with huge potential to change the lighting industry for the better. Don`t know much about them? Here are three big things you need to know to get your feet under you:
1.What Does LED Stand For?
2.LED stands for light-emitting diode.
A diode is an electrical device or component with two electrodes (an anode and a cathode) through which electricity flows - characteristically in only one direction (in through the anode and out through the cathode). Diodes are generally made from semi-conductive materials such as silicon or selenium - substances that conduct electricity in some circumstances and not in others (e.g. at certain voltages, current levels, or light intensities).
2.A light-emitting diode is a semiconductor device that emits visible light when an electrical current passes through it. It is essentially the opposite of a photo-voltaic cell (a device that converts visible light into electrical current).
Did You Know? There is a similar device to an LED called an IRED (Infrared Emitting Diode). Instead of visible light, IRED devices emit IR energy when electrical current is run through them.
1.How Do LED Lights Work?
2.It`s really simple actually, and very cheap to produce, which is why there was so much excitement when LED lights were first invented!
The p-type and n-type materials are created by introducing the original material to atoms of another element. These new atoms replace some of the previously existing atoms and in so doing, alter the physical and chemical structure. The p-type materials are created using elements (such as boron) that have less valence electrons than the intrinsic material (oftentimes silicon). The n-type materials are created using elements (such as phosphorus) that have more valence electrons that the intrinsic material (oftentimes silicon). The net effect is the creation of a p-n junction with interesting and useful properties for electronic applications. What those properties are exactly depends mostly on the external voltage applied to the circuit (if any) and the direction of current (i.e. which side, the p-type or the n-type, is connected to the positive terminal and which is connected to the negative terminal).
Application of the Technical Details to LED Lighting:
When a light-emitting diode (LED) has a voltage source connected with the positive side on the anode and the negative side on the cathode, current will flow (and light will be emitted, a condition known as forward bias). If the positive and negative ends of the voltage source were inversely connected (positive to the cathode and negative to the anode), current would not flow (a condition known as reverse bias). Forward bias allows current to flow through the LED and in so doing, emits light. Reverse bias prevents current from flowing through the LED (at least up until a certain point where it is unable to keep the current at bay - known as the peak inverse voltage - a point that if reached, will irreversibly damage the device).
