Introduction

Electrical conductance is the property of an electrical conductor that determines how fast it contacts – how easily current flows through it (Shaw, 1911, p. 281). When a potential difference is applied across various types of conductors, current flows through the conductors at different rates. The rate at which the current flows through a particular conductor for a particular potential difference is dependent on the specific property of the conductor, referred to as electrical conductance. Conductance determines how well current flows through a particular conductor. Conductance is the inverse (reciprocal) of the property of the conductor ...

Aims and Objectives of the Experiment

This experiment aims at studying the characteristics of titrations with the strength of different acids used in these titrations. This is done by drawing the titration curves of the different titrations that are carried out in this experiment and interpreting those curves. The units of measurement for this experiment are the standard units that are used in titrations. These are molarity (moles/liter) of substances while the quantities are measured in mL (milliliter).

Theory and Principles

Conductometry is a type of electroanalytical method in analytical chemistry. While other electroanalytical methods use equilibria or electrodes, conductometry is different and employs the conductance of materials ...

Summary Of Proposed Research

Global drought not only affects the world agriculture and economics, but interactively affects the phenotypic trait of plants across a different diversity gradient. Nevertheless, plants are able to adapt themselves to the drought environment by changing their phenotypic trait. From previous research at Jena Drought Experiment, in Germany, the results show that diversity not only has the capability to increase community’s resistance to drought, but also to increase community’s recovery ability after drought. On the other hand, the results show that the drought environment makes a strong selection on both, the plant phylogeny and functional trait. Yet, ...

Abstract:

The principal intention of this study was to come up with the most conducive internal environment in a building. At any given moment, the internal temperature of a building is a function of the amount of heat produced by sources therein and the net heat transfer into or out of the building. The four heat transfer modes are convection, radiation, conduction, and phase- change. In executing this project, the researchers sought the relevant literature to establish the thermal properties of various materials. The properties are critical in determining the amount of heat inflow and exit from the building. The ...

The purpose of this paper is to review the etiology, pathophysiology, clinical manifestations, inheritance patterns, and recent advances in disease management of cystic fibrosis. Cystic fibrosis is a progressive and lethal disease resulting from an autosomal recessive gene (Singh, Rebordosa, Bernholz, & Sharma, 2015). The major problem associated with cystic fibrosis is the repeated lung infections that over time severely damage the lungs, scar and widen the passageways and limit the ability to breathe (Cystic Fibrosis Foundation, n.d.). As of 2013, there are an estimated 70,000 cystic fibrosis patients globally with 33,000 of them in the United States ( ...

Abstract

In this article, a new bias current regulation circuit of a one-stage bipolar and Filed Effect Transistor amp is described. How the FET achieves high precision and simplicity by means of a combination of feedback error amplifier with a bandgap reference is explained.

Introduction

Regulating current through active devices sets the output level in a drive circuit. Figure 1. Below shows typical application of these active devices. Qo I used as a FET rather than a BJT. In a limiting amp, the Qo acts as a switch and the output signal level is proportional to the bias current. The gain ...

Discuss in detail the mechanism of action of named antiepileptic agents with reference to the relative clinical success of a particular mechanism in the treatment of epilepsy Carbamazepine is a Sodium channel Blocker. It is the major first line antiepileptic drug. It is used for the treatment of partial seizures and generalized tonic-clonic seizures. Carbamazepine blocks sodium channels during rapid, sustained neuronal firing. It also prevents post-tetanic potentiation. Phenytoin is also another first-line drug for the treatment of partial and secondary generalized seizures. Its mechanism of action is to block the movement of ions through the sodium channels during ...
