Direct spectroscopic evidence for a hydride bridge in the Ni-R form of [NiFe] hydrogenase has been obtained using iron-specific nuclear resonance vibrational spectroscopy (NRVS). The Ni-H-Fe wag mode at 675 cm(-1) is the first spectroscopic evidence for a bridging hydride in Ni-R as well as the first iron-hydride-related NRVS feature observed for a biological system. Although density function t...

This paper focuses on an event, the World Alternative Games (WAG), as a site for development and maintenance of community. The research shows how rural community uses its own interpretation space to create new activities, inspire collaborative promote tourism within particular locale. Drawing upon ethnographic undertaken at third edition WAG in 2016, it provides social constructivist account pa...

The continuous fast pyrolysis of soybean oil in a pilot plant was investigated. The experimental runs were carried out according to an experimental design alternating the temperature (from 450 to 600 degrees C) and the concentration of water (from 0% to 10%). The liquid products were analyzed by gas chromatography and by true boiling point (TPB) distillation. A simple distillation was used to o...

We apply adjoint-based optimization to a Surfactant-Alternating-Gas foam process using a linear foam model introducing gradual changes in gas mobility and a nonlinear foam model giving abrupt changes in gas mobility as function of oil and water saturations and surfactant concentration. For the linear foam model, the objective function is a relatively smooth function of the switching time. For t...

population growth as well as development of industry and agriculture has increased the demand and competition over water resources in large watersheds especially in zayandeh rud basin and severely affected on agriculture and environment sectors. hence, providing a best scenario for the allocation of water in this basin is essential. in this study, due to alternating periods of wet, drought and ...

This paper describes the input specification language of the WAG Sentence Generation system. The input is described in terms of Halliday's (1978) three meaning components, ideational meaning (the propositional content to be expressed), interactional meaning (what the speaker intends the listener to do in making the utterance), and textual meaning (how the content is structured as a message, in ...

The present studies sought to determine the concentrations of endogenous kynurenic acid (KYNA) and to measure the activity of kynurenine aminotransferases (KAT) I and II in the discrete brain regions of 3- and 6-month old WAG/Rij rats, a genetic model of absence epilepsy. Analogues experiments were performed using age-matched ACI rats, which served as a non-epileptic control. The age-dependent ...

It is well accepted that absence epilepsy is not accompanied by structural brain abnormalities. In the present report, we challenged this view based on microscopic analysis of neocortex in a genetic model of absence epilepsy, WAG/Rij rats. Density of neurons and glial cells was measured in the motor, somatosensory and cingular cortical areas in epileptic WAG/Rij rats and in non-epileptic contro...

eries, water in egg-hatching or fry-rearing tanks may have a condition called “gas supersaturation” that is harmful to fish. Gas supersaturation means that the water contains more gas at a certain air (barometric) pressure and water temperature than would normally occur if the water was allowed to come to equilibrium with the atmosphere. Fish living in such waters may develop a stressful or let...
