PURPOSE OF THE STUDY Behavior problems are common in nursing homes. Current guidelines recommend nonpharmacological interventions (NPHIs) as first-line treatment, but pharmacological regimens (PIs) continue to be used. Given differences in background and training of those who treat behavior problems in residents, we compared attitudes of physicians (MDs), psychologists (PhDs), and nurse practit...

the permeability is a main property of oil reservoirs that shows the ability of rocks in the conduct of fluids such as oil, water and gas through the pore spaces of reservoir. the determination of the permeability is a crucial task in reserve estimation, production and development of oil reservoirs. due to this, an accurate estimate of such important reservoir rock parameter should not be made ...

We have used a Wavelet Based Fractal Analysis (WBFA) and a Waveform Classifier (WC) to recognize lithofacies at the Oritupano A field (Oritupano-Leona Block, Venezuela). The WBFA was applied first to Sonic, Density, Gamma Ray and Porosity well logs in the area. The logs that give the best response to the WBFA are the Gamma Ray and NPHI (porosity) logs. In the case of the logs, the lithological ...

Permeability is a vital parameter in reservoir engineering that affects production directly. Since this parameter's significance obvious, finding way for accurate determination of permeability essential as well. In paper, the two notable carbonate reservoirs (Ilam and Sarvak) southwest Iran was predicted by several different methods, level accuracy all models compared. For purpose, Multi-Layer ...

Porosity is one of the fundamental petrophysical properties that should be evaluated for hydrocarbon bearing reservoirs. It is a vital factor in precise understanding of reservoir quality in a hydrocarbon field. Log data are exceedingly crucial information in petroleum industries, for many of hydrocarbon parameters are obtained by virtue of petrophysical data. There are three main petrophysical...

Standard neutron fields are invariably accompanied by a photon component due to the neutron-generating reactions and secondary neutron interactions in the surrounding environment. A set of energy-compensated Geiger-Müller (GM) tubes and electronic personal dosemeters (EPDs) have been used to measure the photon dose rates in a number of standard radionuclide and accelerator-based neutron fields....

The P10 well is located offshore, in the Northern part of Rio Del Rey basin southwest Cameroon. Although most prolific coastal Cameroon given production results from several fields southern part, yet it remains very little explored its northern part. This work evaluation petroleum potential Basin using a combination "Quick Look" interpretation logs recorded and "compl...

our NPHI creation effort started in earnest. We are particularly grateful to the staff of FIOCRUZ, the NPHI in Brazil, and part of a sub-network of Portuguese-speaking NPHIs, for their assistance. the support of the Instituto de Higiene e Medicina Tropical of Portugal, the Centro de Medicina Tropical has been created and inaugurated by the President of Guinea Bissau and the Prime Minister of Po...

Investigation of Hydrocarbon reservoir is important, so it is essential to predict and explore them precisely. One of the methods is well logging, which can transfer the probe or tool in the well to measure one or more characteristics. Nuclear well logging includes radioisotope source and at least one detector. In this work, emission direction of neutrons from the 241Am-Be neutron source toward...
