Abstract: Described herein is N-[4-[4-(4-morpholinyl)-7H-pyrrolo[2,3-d]pyrimidin-6-yl]phenyl]-4-[[3(R)-[(1-oxo-2-propen-1-yl)amino]-1-piperidinyl]methyl]-2-pyridinecarboxamide (Compound A) (Formula I), including crystalline forms, solvates, and pharmaceutically acceptable salts thereof. Also disclosed are pharmaceutical compositions or pharmaceutical formulations that include the compound, as well as methods of using the compound, alone or in combination with other therapeutic agents, for the treatment of autoimmune diseases or conditions, heteroimmune diseases or conditions, cancer, including lymphoma, diabetes, and inflammatory diseases or conditions.

Abstract: A rural landscape-type nitrogen and phosphorus ecological interception ditch system and a farmland drainage nitrogen and phosphorus interception method using the system are provided. The system includes a sediment buffer zone, an ecological ditch unit, an interception-conversion pool and a field ridge hedge fence; the sediment buffer zone, the ecological ditch unit, and the interception-conversion pool are sequentially arranged in a continuous ditch along a direction of a water flow; and the field ridge hedge fence is arranged on field ridges on one side or both sides of the ditch. The present disclosure can, on the basis of not affecting normal production functions of a farmland, further exert an ecological role of the farmland, and use the farmland as an assimilation sink for environmental nitrogen and phosphorus, so as to optimize drainage water quality and improve a farmland ecological environment.

Abstract: A diesel engine includes a cylinder head, a cylinder sleeve, a piston, an injector, and a combustion chamber. The top side of the piston includes an annular top surface, an annular collision belt and an annular cavity. The collision belt includes a collision surface, an upper guide surface, and a lower guide surface. An annular throat is formed between the upper guide surface and the cylinder head. The collision belt divides the combustion chamber into a headspace and a central portion. The volume of the headspace is more than three times of the volume of the central portion. A major portion of the fuel jet injected by the injector is directed into the headspace. The results are faster mixing of fuel and air and complete combustion in the combustion chamber, and a reduction of fuel consumption rate by 2%. A method for fuel distribution and combustion is also disclosed.
