helicopter-borne frequency-domain electromagnetic (hem) surveys are used extensively for mineral and groundwater exploration and a number of environmental investigations. to have a meaningful interpretation of the measured multi- frequency hem data, in addition to the resistivity maps which are provided in each frequency or for some particular depth levels, it is a necessity to have a suit...

the benefits of textual input enhancement in the acquisition of linguistic forms have produced mixed results in sla literature. the present study investigates the effects of textual enhancement on adult foreign language intake of two english linguistic forms-subjunctive mood and inversion structures-to explore the role of the type of linguistic items in input enhancement studies. it also invest...

An algorithm for the retrieval of total column amount trace gases in a multi-dimensional atmosphere is designed. The uses (i) certain differential radiance models with internal and external closures as inversion models, (ii) iteratively regularized Gauss–Newton method regularization tool, (iii) spherical harmonics discrete ordinate (SHDOM) linearized radiative transfer model. For efficiency rea...

Nitrous oxide (N 2 O) emissions from arable soils are predominantly caused by denitrifying microbes, of which fungal denitrifiers particular interest, as fungi, in contrast to bacteria, terminate denitrification with N O. Reduced tillage has been shown increase gaseous nitrogen losses soil, but knowledge how varying regimes and associated soil physical chemical alterations affect is limited. Ba...

Abstract In this manuscript, we present an approach for computing tunneling splittings large amplitude motions. The core of the is a solution effective one-dimensional Schrödinger equation with mass and potential energy surface composed electronic harmonic zero-point vibrational energies small motions in molecule. method has been shown to work cases three model motions: nitrogen inversion ammon...

background: inversion of the uterus is very uncommon. patients may present with pelvic pain, vaginal discharge, or hemodynamic shock. case: we report a case of 35 years old women (virgin) who was admitted with profuse vaginal bleeding and cramps of uterus. in the vaginal examination at litothomy position a mass of 58 cm in size was protruded from the vagina. at first myomectomy was performed a...

A method is described by which it is possible to determine the high barrier to ring inversion and hindered rotation by neat racemization of optically active compounds when the racemization is caused by ring inversion or hindered rotation. The method is based preparation of sufficiently pure enantiomers, mainly by chromatography on swollen microcrystalline triacetylcellulose (TAC). By this t...

abstract improving nitrogen use efficiency (nue) is an important objective of the agroecosystem management. a field experiment was conducted to study the effect of different competition patterns on nitrogen balance in the wheat agroecosystem. experimental design was split–plot based on randomized complete blocks with four replications. the main plots consisted of different nitrogen rates (i.e. ...

Conventionally, the singly occupied molecular orbital (SOMO) of a radical species is considered to be the highest occupied molecular orbital (HOMO), but this is not the case always. In this study, we considered a number of radicals from smallest diatomic anion radicals such as superoxide anion radical to one-electron oxidized DNA related base radicals that show the SOMO is energetically lower t...
