We propose a new method to maximize biomarker efficiency for detecting anatomical change over time in serial MRI. Drug trials using neuroimaging become prohibitively costly if vast numbers of subjects must be assessed, so it is vital to develop efficient measures of brain change. A popular measure of efficiency is the minimal sample size (n80) needed to detect 25% change in a biomarker, with 95...

In this combined electroencephalographic and magnetic resonance imaging (MRI) study, the asymmetry of functional and structural measures in the human parietal operculum (PO) were investigated. Median nerve somatosensory evoked potential recordings showed maximum scalp potentials over contralateral (N80, N110) and ipsilateral (N100, N130) temporal electrode positions. In accordance, MRI-coregist...

The inhibition of the corrosion of N80 steel in 3.5 wt. % NaCl solution saturated with CO2 by four porphyrins, namely 5,10,15,20-tetrakis(4-hydroxyphenyl)-21H,23H-porphyrin (HPTB), 5,10,15,20-tetra(4-pyridyl)-21H,23H-porphyrin (T4PP), 4,4',4″,4‴-(porphyrin-5,10,15,20-tetrayl)tetrakis(benzoic acid) (THP) and 5,10,15,20-tetraphenyl-21H,23H-porphyrin (TPP) was studied using electrochemical impedan...

PURPOSE To investigate whether the pattern reversal visual evoked potential can be useful in the diagnosis and management of macular hole patients. METHODS The pattern reversal visual evoked potential was measured in 66 patients with a macular hole and in 43 healthy control subjects. Check sizes of 34', 17' and 10' were applied. RESULTS Results showed that, for the check sizes of 34', 17' a...

An investigation into the mechanical properties of K55, N80, and P110 steels commonly used for casing drilling was carried out together with microstructural fractographic analysis. The results show that steel consisted almost fully tempered martensite exhibited a synergy combination static tensile, dynamic impact, fatigue crack propagation among three steels, possessing higher limit deeper tole...

Excessive application of nitrogen (N) fertilizer will cause many adverse consequences in paddy fields, especially for the reduction N use efficiency. Biochar can be used to replace part rice production. A field experiment 2-year/four-season was conducted investigate effects combined with straw biochar on yield, soil fertility, and The contained six treatments: No (CK), customary (N100), 20% (N8...

Oil well are periodically acidized for enhancing oil flow. Inhibited hydrochloric acid is used during acidization to prevent corrosion of N80 or J55 steel. In the present work authors have surveyed literature on acidizing corrosion inhibitors and the salient features of research work carried out by the authors have also been highlighted.

We implement the Predicting Particles Produced in Power-Plant Plumes (P6) sub-grid sulphate parameterization for the first time into a global chemical-transport model with online aerosol microphysics, the GEOS-Chem-TOMAS model. Compared to simulations using two other previous treatments of sub-grid sulphate, simulations using P6 subgrid sulphate predicted similar or smaller increases (depending...
