the study examined gender analysis of energy use for rice production in north central nigeria using a sample of 60 rice farmers. an analysis of gender relations provides the information on the different conditions men and women face, and the different effects that policies and programs may have on them. simple descriptive statistics were used to analyze the data. energy efficiency and energy pr...

We present comparisons of the fully differential exact virtual correction to the important single hard bremsstrahlung process in e + e − annihilation at high energies , which is essential for precision studies of the Standard Model from 1 GeV to 1 TeV, as calculated by two completely independent methods and groups. We show that the two sets of results are in excellent agreement. Phenomenologica...

This thesis focuses on hadronic spin structure at low and intermediate energies, 0 < Q2 < 3 GeV 2. The thesis is divided into two main sections. Each section addresses a different aspect of spin dependent hadronic physics which has not been studied previously in detail. The first section studies hydrogen hyperfine splitting. A polarizability term depending on the proton's G1 and G2 spin depende...

In this paper an optimal controller is proposed for a self-balancing electrical vehicle called Segway PT. This vehicle has one platform and two wheels on the sides and the rider stands on the platform. A handlebar, as a navigator, is attached to the body of Segway, with which the rider controls the vehicle. Since Segway uses electrical energy produced by batteries, resource consumption manageme...

Electricity is the key to the proper functioning of modern human society. It is important to maintain and even reduce the level of consumed energy in the world. This gives rise to recent regulations and significant endeavors to improve the energy efficiency in all kinds of human activity from manufacturing to commerce, from transportation to digital communication, from entertainment to laptops ...

The CBS-QB3 method was used to calculate the gas-phase free energy difference between 20 phenols and their respective anions, and the CPCM continuum solvation method was applied to calculate the free energy differences of solvation for the phenols and their anions. The CPCM solvation calculations were performed on both gas-phase and solvent-phase optimized structures. Absolute pK(a) calculation...

in this paper, the energy demand of transport sector from 1385 to 1400 is forecasted based on fuzzy linear regression (flr) approach considering economic and social indicators. in order to analyze the influence of economic and social indicators on energy demand of transport sector, gross domestic product (gdp), population and the total number of vehicles in 1372-1384 were regarded. in this rese...

The Micro-Grid (MG) stability is a significant issue that must be maintained in all operational modes. Usually, two control strategies can be applied to MG; V/f control and PQ control strategies. MGs with V/f control strategy should have some Distributed Generators (DGs) which have fast responses versus load changes. The Flywheel Energy Storage System (FESS) has this characteristic. The FESS, w...

The electric charges on an enzyme may move concomitantly with a conformational change. Such an enzyme will absorb energy from an oscillating electric field. If in addition the enzyme has a larger association constant for substrate than for product, as is often true, it can use this energy to drive the catalyzed reaction away from equilibrium. Approximate analytical expressions are given for the...
