1. Raw milk. It contains a toxic trypsin inhibitor that is easily poisoned after drinking. Therefore, soy milk must be thoroughly cooked before drinking. What needs to be reminded is that when milk is heated to a certain level, foam will appear. This does not mean that it has been cooked. It should continue to heat for 5-10 minutes until the foam disappears. 2. Vegetables and fruits grown in greenhouses. Plants grown in greenhouses require a large amount of pesticides. In addition, winter cold can cause pesticides to be absorbed completely when plants are used for photosynthesis. Therefore, cleaning will not result in pesticide poisoning when eating fruits and vegetables in winter. 3. Rotten cabbage. The leaves of Chinese cabbage contain more nitrates, which will increase significantly after rot. Once ingested in large quantities, it will be reduced to nitrite and poisoned by intestinal bacteria. Mainly manifested as dizziness, vomiting, etc., severe breathing difficulties, blood pressure decreased. To prevent poisoning, avoid long-term storage of vegetables at high temperatures. 4. Sprouted or immature potato. It contains toxic substances solanine, which can cause poisoning after ingestion. In winter, the potatoes should be stored at low temperature and without direct sunlight; when cooking, a little vinegar can be added to destroy the toxins. 5. Mildew sugar cane. Its toxicity is very strong, eating 2-8 hours after the emergence of vomiting, dizziness, headache, visual impairment and other symptoms, severe cases also coma, respiratory failure, mortality and sequelae rate of up to 50%, there is currently no effective treatment. When suspected food poisoning is found, it should be sent to the hospital as soon as possible, and at the same time, the suspicious food, the patient's vomiting and excrement should be seen by the doctor. Try to induce vomiting during treatment to reduce toxin absorption by pressing the tongue with your finger or spoon and causing the patient to vomit. When vomiting, the patient should face down and head down to prevent vomit blocking the airway. At the same time, remember that conscious patients must not induce vomiting.
Optical Windows are flat, plane-parallel plates that are often used as protective barriers for electronic sensors or detectors from outside environments. Optical Windows should be selected based on the material transmission or mechanical properties of the substrate. Optical Windows do not cause change in the magnification of a system. Worldhawks` Optical Windows are offered in a variety of substrates, such as Germanium (Ge), Silicon (Si), N-BK7(H-K9L), UV Fused Silica, Zinc Selenide (ZnSe). Multiple anti-reflection coating options are available for the Ultraviolet (UV), visible, or Infrared (IR).
Worldhawk offers standard and high precision optical glass windows in round ,rectangular, wedge windows and custom shape and size with different optical glasses,Fused Silica, Sapphire, ZnSe, Zns and IR crystal. The high precision parallelism of 10 arc seconds, surface quality of 40/20 and flatness of λ/10. Single layer or multi-layer anti-reflection coatings are available.
