Before rotating the tillage operation, the arrangement of the rotary knife is an important task. Improper installation will seriously affect the quality of the work, and due to unbalanced blade rotation, it will lead to mechanical damage and increased unit vibration, and is not safe. In order to make the rotary cultivator work, to avoid ploughing and plugging, the knife shaft is evenly distributed, and the arrangement of the blades on the knife shaft should meet the following requirements: 1. Configure more than two blades, and ensure that the amount of cut-off soil is equal to achieve good quality of the soil. After the cultivation, the bottom of the groove is leveled. 2. During one revolution of the cutter shaft, at the same phase angle, a knife must be inserted into the earth to ensure the stability of the work and the load of the cutter shaft. 3. For inserts that are successively inserted into the soil, the greater the axial distance on the cutter shaft, the better so that clogging does not occur. 4. The left and right bending blades should be staggered as much as possible so that the bearings at both ends of the cutter shaft are balanced by force. The general blades are arranged in a helix. There are three ways to install the rotary knife: 1. When installed, all blades are facing the center of the cutter shaft. After cultivating, the middle of the floor is raised. 2. In addition to the outermost two blades, the outer covers are all installed outward. After cultivating, the middle of the ground is concave. 3. Mixed inserts are staggered inside and outside. After cultivating, the surface is smooth. Workers and peasants 12-K walking tractors commonly used in all parts of Guangdong Province are equipped with rotary cultivators. There are a total of 16 blades on the cutter shaft. The left and right halves are arranged in a staggered manner for paddy fields and dry lands, especially the cultivation of vegetable fields. Better. When installing the rotary blade, pay attention to the cutting edge toward the earth. (Yellow Pine Year)
Anticancer pharmceuticals are used to make anticancer drugs. Such as Imatinib Mesilate, Ibrutinib, and Lapatinib. Within the past 2 years, four separate groups have reported marked improvement in relapse-free survival when trastuzumab was added to adjuvant chemotherapy in patients with HER2-overexpressing breast cancer.
Imatinib (also known as [Gleevec" or [Glivec"), a tyrosine kinase inhibitor, was called as [magical bullet," when it revolutionized the treatment of chronic myeloid leukemia (CML) in 2001. Nano-encapsulation of imatinib mesylate increases its efficacy against cancer cells, with almost no cardiotoxicity.
Lapatinib is a tyrosine kinase inhibitor which can effectively inhibit the tyrosine kinase activity of human epidermal growth factor receptors 1 and 2 (ErbB1, ErbB2). It can uniquely act in a variety of ways, ensuring that breast cancer cells cannot receive growth signals.
