The title compound, C7H7ClN2O, crystallizes with two independent mol-ecules in the asymmetric unit. The compound adopts an E configuration across the C=N double bond, as the -OH group and the benzene ring are on opposite sides of the double bond while the H atom of the hy-droxy group is directed away from the -NH2 group. In the crystal, mol-ecules are linked to one another through O-H⋯N and N-H...

The title compound, C19H20O6, consists of a tetra-substituted benzene ring with one substituent being an α,β-unsaturated cinnamoyl group, which forms an extended conjugated system in the mol-ecule. In addition, two meth-oxy-meth-oxy and one hy-droxy group are bonded to the central benzene ring. The dihedral angle between eh rings is 10.22 (10)°. An intra-molecular hydrogen bond is observed betw...

In the crystal of the title compound, C(14)H(17)NO(2), mol-ecules are arranged into chains along the b axis linked via O-H⋯O hydrogen bonds. While the benzene ring is essentially planar, with a maximum deviation from the best plane of 0.003 (1) Å, the pyridine ring is slightly V-shaped: the distance of the carbonyl C atom from the benzene best plane is 0.120 (1) Å. The hy-droxy group is incline...

Modifying of HY/Zeolite is by loading nickel for applying catalyst in thermal catalytic cracking furfural extract-40 from the lubricating base oil unit. The study involved characterizing HY-zeolite and promoted with X-ray diffraction analysis, Scanning electron microscopy (SEM), BET (Brunauer, Emmett, Teller), infrared ray analyses FTIR. tubular reactor a fixed bed two type catalysts; HY/zeolit...

Haiyang-2 (HY-2) missions have accumulated sea surface height (SSH) observations on a global scale for more than 10 years. Four satellites, HY-2A, HY-2B, HY-2C and HY-2D, provide even but differently distributed data, which play complementary role in marine gravity studies with other missions. Therefore, this paper evaluates the performances of HY-2 altimetric data modeling from following four ...

The operation of reforming catalysts in a fixed bed reactor undergoes high level interaction between the operating parameters and reaction mechanism. Understanding such an reduces catalyst deactivation rate. In present work, three kinds nanocatalysts (i.e., Pt/HY, Pt-Zn/HY, Pt-Rh/HY) were synthesized. catalysts’ performances evaluated for n-heptane reactions reactor. conditions applied followin...

Acute infections with viruses such as lymphocytic choriomeningitis virus (LCMV) are associated with a massive polyclonal T cell response, but the specificities of only a small percentage of these activated T cells are known. To determine if bystander stimulation of T cells not specific to the virus plays a role in this T cell response, we examined two different systems, HY-specific T cell recep...

Current models of T cell memory implicate a critical role for IL-7 in the effector-to-memory transition, raising the possibility that IL-7 therapy might enhance vaccine responses. IL-7 has not been studied, to our knowledge, before now for adjuvant activity. We administered recombinant human IL-7 (rhIL-7) to mice during immunization against the male antigen HY and compared these results with th...

The thymic medulla is generally held to be a specialized environment for negative selection. However, many self-reactive thymocytes first encounter ubiquitous self-antigens in the cortex. Cortical epithelial cells are vital for positive selection, but whether such cells can also promote negative selection is controversial. We used the HY(cd4) model, where T cell receptor for antigen (TCR) expre...
