this paper investigates the kinetics of structure h (sh) formation kinetics above and below the structure i (si) formation equilibrium curve at temperatures of between 2â°c and 6â°c. methane was used as a help gas and methylcyclohexane (mch) was used as sh former. it was concluded that in the points above the si formation equilibrium curve, at the first, the si forms, and then converts to sh be...

A higher generation dendron with a long-alkyl chain thiol (DA2-SH) induced the formation of nanoparticles with a small core with quite a narrow size distribution (1.5 +/- 0.1 nm), the self-assembly of one-dimensional arrays of these gold nanoparticles (DA2-Au), and the stabilization for the formation of the radical cation of the phenothiazine of DA2-Au nanoparticles from the interfacial one-ele...

A s evidenced in Paleolithic cave paintings of fi sh dating from 17,000 years ago, human-fi sh interactions have existed for thousands of years (Valladas et al. 2001). The earliest interactions likely involved fi sh as food and were necessarily tied to geographic access (i.e., island or coastal locations). Over time, the establishment of farm fi shing and the emergence of modern capture and tra...

the existing theory for wave propagation through a soil layer are not compatible with the real soil layers because in the theory the layers are flat and the sub-layers are parallel, while in real the soil layers are not flat and they may not be parallel. thus, wave propagations through a corrugated interface are so important. in this paper, a two-dimensional sh-wave propagation through a corrug...

BACKGROUND AND OBJECTIVES Self harm is a serious public health problem worldwide. Implicit attitude measures offer a novel method of exploring associations with self harm (SH). Here we used implicit measures in order to (i) examine implicit evaluative and arousal associations with SH (ii) compare the discriminatory power of implicit and explicit attitude measures in a non-clinical sample at hig...

We used the teleost Astyanax mexicanus to examine the role of the lens in optic nerve and tectum development. This species is unusually suited for studies of nervous system development and evolution because of its two extant forms: an eyed surface dwelling (surface fi sh) and several blind cave dwelling (cavefi sh) forms. Cavefi sh embryos initially form eye primordia, but the lens eventually d...

Abstract Compared with conventional drilling methods, the method of horizontal wells a slim hole (HW‐SH) has advantages, such as high productivity, environment‐friendliness, and low costs. However, during process, narrow annulus may become blocked, which lead to an increase in pressure if wellbore is not clean. This often leads serious accidents, sticking leaking formations. Many models have be...

Accurate and economical modeling of near-surface transport processes is a standing challenge for various engineering atmospheric boundary-layer flows. In this paper, we address by utilizing an stochastic one-dimensional turbulence (ODT) model. ODT aims to resolve all relevant scales turbulent flow domain. Here applied channel as stand-alone tool. The domain wall-normal line that aligned with th...

Studies of protein-bound (PB-SH) and nonprotein bound sulfhydryl group (NP-SH) concentrations in tissues under various conditions is a prerequisite to understanding the role of sulfhydryls in living organisms. Many methods have been developed for the measurement of sulfhydryl groups, but these have been concerned chiefly only with the estimation of NP-SH in biological fluids or total SH groups ...
