摘要:
A macromonomer capable of forming a graft polymer through graft-through polymerization, the macromonomer including a plurality of monomer units including a cycloalkene having a fused ring attached thereto to form a cycloalkene-fused ring monomer where the fused ring decreases the ring strain energy of the cycloalkene to a lower ring strain energy state of 5.3 kcal/mol or lower and where the cycloalkene of the cycloalkene-fused ring monomer is capable of isomerization into a higher ring strain energy state before graft-through polymerization, and at least one polymer sidechain is bonded to the fused ring. Graft polymers formed by the macromonomer include graft polymers and graft copolymers including statistical and block copolymers. The graft (co)polymers are capable of depolymerization under mild conditions into reusable monomer units.

The invention relates to a method and a kit for the detection of Trichomonas infection by detecting N-acetyl-β-D-hexosaminidase activity. The invention also relates to a method and a kit for selective detection of presence of Trichomonas or Candida infection.
摘要:
This discloses a process for catalytically cracking hydrocarbon stocks in a riser or fluidized bed reactor simultaneously to increase yields of diesel and liquefied gas. The process includes the steps of: first, charging a gasoline stock and a catalytic cracking catalyst into a lower zone of the reactor to permit contact between the catalyst and the gasoline stock and to produce a liquefied gas-rich oil-gas mixture containing reacted catalyst. The resulting liquefied gas-rich oil-gas mixture (still containing reacted catalyst) is then introduced into a reaction zone above the lower zone of the reactor. Simultaneously, at least one conventional catalytic cracking hydrocarbon feed is also fed independently into at least two sites is situated at a different height above the lower zone of the reactor. The resulting mixture is then separated in a conventional fashion.
摘要:
A method and a kit for the detection of Trichomonas infection by detecting N-acetyl-β-D-hexosaminidase activity in a sample, and a method and a kit for the detection of Trichomonas or Candida infection by detecting N-acetyl-β-D-hexosaminidase activity in a sample. The presence of a Trichomonas or a Candida infection can be distinguished by a pH of the sample.
