In deciduous forests, soil moisture is an important driver of numerous physical, microbial, and biogeochemical processes. Therefore, characterizing the interactions between vegetation and soil moisture is critical to forecast long-term water resources and ecosystem health. However, these interactions are difficult to measure, both in time and space. Recent studies have shown the ability of elec...

Coastal lands around Bay of Bengal in Central Godavari Delta are mainly agriculture fields and two times annually paddy crops putting in the study area. Canals of Godavari River are the main source of water for irrigation. Geophysical and geochemical investigations were carried out in the study area to decipher subsurface geologic formation and assessing seawater intrusion. Electrical resistivi...

We used a porcine endotoxemic model of acute lung injury to compare extravascular lung water (EVLW) measured by right transthoracic bioimpedance to postmortem gravimetric EVLW measurements. Adult pigs were randomized into control (N = 5) or endotoxin groups [150 microgram/kg Escherichia coli lipopolysaccharide B for 1 hr followed by 3 hr of resuscitation for a thermodilution cardiac output less...

In the United States, nursing programs are commonly evaluated by their graduates success on the National Council Licensure Examination for Registered Nurses (NCLEX-RN c ©). The purpose of this paper is to describe a change in NCLEX-RN c © success rates following the addition of standardized exams throughout our program’s curriculum, and to compare these exam scores between graduates who pass NC...

An effort-reward imbalance (ERI) model is a measurement of psychosocial work stress. The ERI model with both the effort-reward ratios and the concept of overcommitment (OC) indicates that work stress is related to high effort with low reward. Effort is evaluated by measuring work demands. Reward includes money, esteem, status, and control over promotion prospects, and job security. Overcommitme...

This paper describes the application of a new methodology to estimate permeability of clastic rock formations based on the numerical simulation of the physics of mudfiltrate invasion. The methodology assumes a key well with a complete suite of well logs and rock-core laboratory measurements of porosity, permeability, capillary pressure, and relative permeability. For additional wells in the sam...

An automatic technique is developed for integrating two electrical resistivity logs obtained during Leg 133, namely, the deep induction log (ILD) and the spherically focussed log (SFL). These logs are routinely run by the Ocean Drilling Program in lower resistivity sedimentary environments, where drilling through soft, poorly consolidated lithologies often results in variable hole diameters. Ex...

Electrical resistivity (ER) is a main parameter in the melting processes of glasses. However, its measurement is difficult at high temperatures. In this study the electrical resistivity of different cordierite glass samples in the molten state was measured in the temperature range of 1100˚C to 1550 ˚C using the two-wire method. It was attempted to decrease the electrical resistivity of the glas...
