We present three-frequency VLA observations of the flocculent spiral galaxy NGC 4414 made in order to study the magnetic field structure in absence of strong density wave flows. NGC 4414 shows a regular spiral pattern of observed polarization B-vectors with a radial component comparable in strength to the azimuthal one. The average pitch angle of the magnetic field is about 20 • , similar to ga...

The potential hazards and risks associated with well-stimulation in unconventional oil and gas development (hydraulic fracturing, acid fracturing, and matrix acidizing) have been investigated and evaluated and federal and state regulations requiring chemical disclosure for well-stimulation have been implemented as part of an overall risk management strategy for unconventional oil and gas develo...

In this study, evidence for a factor secreted by bovine hypophyseal pars tuberalis that stimulates luteinizing hormone (LH) release from rat pars distalis cells is shown. The secretion products of bovine pars tuberalis cells into the culture medium were assayed on dispersed rat pars distalis cells in 30 min incubations and superfusion experiments. The culture medium from pars tuberalis total ce...

The substantia nigra pars reticulata (SNR) constitutes a major output nucleus of the basal ganglia where the final stage of information processing within this system takes place. In this study, using juxtacellular labeling and three-dimensional reconstruction methods, we investigated the spatial organization of the intranigral innervation provided by single GABAergic projection neurons from the...

This study aimed to design a strategic model of talent management at Pars Oil and Gas Company (POGC) based on international best practice experience. Research method is a mixed method (qualitative-quantitative) and sampling is done in two phases. In qualitative phase, sample included 24 top managers and senior executives (experts) who were selected by purposive sampling and in quantitative phas...

Based on the latest laboratory test and prospect well data of G layer in south depression of D basin, the source rock、reservoir、cap-rock and preservation forming condition of tight oil and gas within research area is analyzed. The results indicate that the widely distributed dark mudstone of J layer has rather high organic content .IIb and III types are the mainly genetic types of organic matte...

A 55-years-old woman presented with profound sudden loss of vision in left eye (LE) after an injury a road side accident. She had normal right eye. Left perception light (PL) accurate projection (PR) all quadrants, total hyphema, chemosis supero-nasal conjunctiva and intraocular pressure (IOP). B-scan LE showed extrusion the lens into subconjunctival space called phacocele, vitreous hemorrhage....
