Reminder: The diet should be light and fresh.
Green leafy vegetables such as greens and spinach are often cooked twice, and each time they are repeatedly fried, the number of carcinogens increases by several dozen times. This can easily cause cancer... This morning, the “International Symposium on Early Gastric Cancer in China and Japan†was held in Shanghai. According to Professor Wu Yunlin, director of the Department of Gastroenterology at Ruijin Hospital, China is the country with the highest incidence and mortality of gastric cancer. Half of early gastric cancer patients have no symptoms and the diagnostic rate is less than 5%.
“In the 1930s and the 1960s, gastric cancer was also a high-grade tumor in Japan, but with the popularity of refrigerators, people began to get used to 'burn the day to finish the day.' Since the 1970s, the incidence of gastric cancer in Japan has decreased significantly. "Professor Wu Yunlin said that high incidence of gastric cancer is related to improper dietary habits, such as eating overnight vegetables, and picking vegetables.
Professor Ruixin Shen, director of internal medicine at Ruijin Hospital, told reporters: “Green vegetables such as greens and spinach, bean beans, (bean) beans, beans, and other green beans, repeatedly boiled, chlorophyll prone to chemical reactions, resulting in degradable components, prone to cancer. However, seafood such as crabs, fish and shrimps are prone to produce protein degradation products overnight, which can damage liver and kidney function.The remaining soup is prosperous in aluminum pans and stainless steel pans and is prone to chemical reactions. In addition, the refrigerator is not a fresh-keeping box, vegetables, fruits and other fresh vegetables for a long time, easy to breed bacteria, as pickles, salted fish, ham, sausage, pickles and other preserved foods, because of the carcinogen nitrite amine Ingredients, should not eat more."
For the prevention and treatment of gastric cancer, Professor Wu Yunlin said that according to the statistics of Japan's Early Gastric Cancer Examination Society, about half of patients with early gastric cancer are asymptomatic. It is reported that the "Gastrointestinal Oncology Discipline Group" led by Ruijin Hospital is being promoted, and a "National Yangtze River Delta Early Gastric Cancer Cooperative Group" is being brewed on the conference.
â– Remind
Prof. Yunlin Yun reminded the public that the daily diet should be light and fresh. Do not eat overnight food. The twice-cooked pork and braised pork also need to be fresh. Place leftovers for no more than 12 hours. Water should not be boiled repeatedly. If the public finds that the upper abdomen is often full of discomfort such as fullness and pain, and gastritis and ulcers are repeatedly unhealed, they must be promptly admitted to the hospital for examination. For high-risk groups such as family history who are over the age of 40, endoscopy should be performed regularly.
Sprinkler irrigation and micro-irrigation automatic control equipment With the development of economy, water resources, energy shortage and labor cost increase, more and more water-saving irrigation systems will adopt automatic control. This article focuses on the advantages and classification of automated irrigation.
The advantages are as follows:
(1) It is possible to truly control the amount of irrigation, irrigation time and irrigation cycle in a timely and appropriate manner, thereby increasing crop yield and significantly improving water utilization.
(2) Saving labor and operating expenses.
(3) The work plan can be arranged conveniently and flexibly, and the management personnel do not have to go to the field at night or other inconvenient time.
(4) Since it can increase the effective working time every day, the initial capital investment in pipelines, pumping stations, etc. can be reduced accordingly.
classification:
First, fully automated Irrigation System
The fully automated irrigation system does not require direct human involvement. The pre-programmed control procedures and certain parameters that reflect the water requirements of the crop can automatically open and close the pump for a long time and automatically irrigate in a certain order. The role of the person is simply to adjust the control program and overhaul the control equipment. In this system, in addition to emitters (heads, drip heads, etc.), pipes, fittings, pumps, and motors, it also includes central controllers, automatic valves, sensors (soil moisture sensors, temperature sensors, pressure sensors, water level sensors, and rain sensors). Etc.) and wires.
Second, semi-automatic irrigation system
In the semi-automated irrigation system, no sensors are installed in the field. The irrigation time, irrigation volume and irrigation period are controlled according to pre-programmed procedures, rather than feedback based on crop and soil moisture and meteorological conditions. The degree of automation of such systems is very different. For example, some pump stations implement automatic control, and some pump stations use manual control. Some central controllers are only one timer with simple programming function, and some systems have no central control. The controller, but only some of the sequential switching valves or volume valves are installed on each branch pipe.
Automated irrigation is the trend of the times. In the future water-saving irrigation projects, more and more automated irrigation systems will be applied.
