The objects that cannot be eaten during menstruation are: 1. Cold type: that is cold food in Chinese medicine, such as: pears, bananas, oysters, stone ear, stone flowers, ear. Many of these foods have the functions of detoxification, nourishing yin and reducing fire. They are beneficial to the human body when used for ordinary food, but during the menstrual period, they should only cause dysmenorrhoea and menstruation if they do not eat or eat less of these foods. Tune other symptoms. 2. spicy categories: such as cinnamon, pepper, Dingxiang, pepper and so on. This kind of food is a seasoning. In the ordinary dishes, when the dish is served with some pepper, the taste of the dish can be better. However, women in the menstrual period are not suitable to eat these spicy spicy food, otherwise easily lead to dysmenorrhea, menorrhagia embolism. It is also necessary to carefully change things: First, not suitable for living Endometrial shedding during the menstrual period, the appearance of the uterine cavity to form a wound, easy to bring bacteria into life, retrograde and long into the uterus, causing intrauterine infection, resulting in inflammation of the annex, pelvic inflammatory disease. Second, do not eat more salt Eating too much salt will increase the body dripping drops and water storage, on the eve of menstrual cramps, will produce headaches, moving and irritability and other symptoms. Low salt food should be eaten starting 10 days before the tide. Third, should not drink tea The high concentration of caffeine in the strong tea stimulates nerves and cardiovascular vessels and is easily gestated to produce dysmenorrhea, delayed menstruation, and excessive menstrual bleeding. At the same time, the tannic acid in the strong tea will render iron reception impeded, causing iron deficiency and blood deficiency.
Everything You Need To Know About LED Lighting
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.It`s really simple actually, and very cheap to produce, which is why there was so much excitement when LED lights were first invented!
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).

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.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?
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).
