Compared with Europe and the United States and other developed countries, China's corn cultivation has the following characteristics: 1, small planting plots, 2 corn planting spacing is not uniform, 3, corn grain moisture content is high during harvest. Therefore, the design requirements of China's corn harvesting machinery are different from those in developed countries such as Europe and the United States. The following points should be achieved:
1. The designed corn harvester should be flexible in operation, transportation and unloading, and it is suitable for small plots in the field.
2. The current development of corn harvesters should be as simple as possible and easy to maintain in view of the current low cultural quality of farmers.
3, the design of the corn harvester can be harvested. Otherwise, it will not only affect the quality of the harvest but also reduce the production efficiency. Affected farmers' enthusiasm for buying corn harvesters.
4, the design of the corn harvester must be able to harvest high-moisture corn (grain moisture content of about 40%), the ear and the grain breakage rate shall not exceed the national standard.
5. To prevent moldy growth, there must be no excessive stems and leaves in the harvested ear of corn.
6, the unit must have good strength and stiffness, can adapt to poor field roads.
7. Harvesting function At the same time, high-quality straw treatment is performed on the straw.
8, the unit has a higher use of reliability.
Antipyretic:
Something that reduces fever or quells it.
There are 3 classes of antipyretic medications that are sold OTC (over-the-counter) without prescription:
Salicylates -- aspirin (acetylsalicylic acid), choline salicylate (Arthropan), magnesium salicylate (Arthriten), and sodium salicylate (Scot-Tussin Original);
Acetaminophen (Tylenol); and
Nonsteroidal anti-inflammatory drugs (NSAIDs) -- ibuprofen (Advil), naproxen (Naprosyn, Aleve), and ketoprofen.
From anti-, against + the Greek pyretos, fever from pyr, fire. The same root gives rise to pyrexia, a medical term for fever.
Antipyretic, from the Greek anti, against, and pyreticus, pertaining to fever, are substances that reduce fever. Antipyretics cause the hypothalamus to override a prostaglandin-induced increase in temperature. The body then works to lower the temperature, resulting in a reduction in fever.
Most antipyretic medications have other purposes. The most common antipyretics in the United States are ibuprofen and aspirin, which are used primarily as pain relievers. Non-steroidal anti-inflammatory drugs (NSAIDs) are antipyretic, anti-inflammatory, and pain relievers.
Pain-killer:
Painkiller is any member of the group of drugs used to achieve analgesia, relief from pain.
Analgesic drugs act in various ways on the peripheral and central nervous systems. They are distinct from anesthetics, which reversibly eliminate sensation. Analgesics include paracetamol (known in North America as acetaminophen or simply APAP), the non-steroidal anti-inflammatory drugs (NSAIDs) such as the salicylates, and opioid drugs such as morphine and oxycodone.
In choosing analgesics, the severity and response to other medication determines the choice of agent; the World Health Organization (WHO) pain ladder specifies mild analgesics as its first step.
Analgesic choice is also determined by the type of pain: For neuropathic pain, traditional analgesics are less effective, and there is often benefit from classes of drugs that are not normally considered analgesics, such as tricyclic antidepressants and anticonvulsants.
