In this paper we have down three theoretical study by using Monte Carlo simulation and Mm+,AMBER and OPLS force field. The calculations were carried out using Hyper Chem professional,release 7.01 package of program. first we have studied the interaction of H2 molecule and He atomwith single-walled carbon nanotube at different temperature. For doing this study we placed H2 andHe in the center an...

Equilibrium adsorption property of multi-walled carbon nanotubes with OH group was studied using experimental design for the adsorption of CO2 , CH4 and H2 . The effect of temperature, pressure, their binary interactions and quadratic terms were studied for adsorption capacity of nanotubes and the results were analyzed by the face centered central composite design method and analysis of varianc...

Background: Overdoses with cardiovascular drugs are related with significant morbidity and mortality. Beta-adrenergic blockers, calcium-channel blockers (CCBs), thiazide, digoxin and angiotensin converting enzyme (ACE) inhibitors represent five of the most important classes of cardiovascular drugs. Overdoses with cardiovascular drugs are typically caused by exploratory ingestion by children or ...

The COVID-19 pandemic has been transformed into one of the main worldwide challenges, in recent years. For controlling symptoms that are caused by this disease (e.g., chills or fever, shortness breath and/or difficulty breathing, cough, sore throat, fatigue, headache, muscle aches, new loss tastes smells, congestion runny nose, nausea, vomiting diarrhea), lots medicines including analgesics, mu...

Molecular hydrogen (H2 ) is an atmospheric trace gas with a large microbe-mediated soil sink, yet cycling of this compound throughout ecosystems is poorly understood. Measurements of the sources and sinks of H2 in various ecosystems are sparse, resulting in large uncertainties in the global H2 budget. Constraining the H2 cycle is critical to understanding its role in atmospheric chemistry and c...

Blockers can take a tiny task and stretch it over days or weeks. Taking moment at the beginning of project to look for prevent possible blockers improve productivity. These examples personal, team, organizational levels show how gathering right information performing preflight checks save hours wasted time later.

This work shows the application of a validated mathematical model for gas permeation at high temperatures focusing on demonstrated scale-up design for H2 processing. The model considered the driving force variation with spatial coordinates and the mass transfer across the molecular sieve cobalt oxide silica membrane to predict the separation performance. The model was used to study the process ...
