Introduction

Tension forces act on liquid surfaces, the thread in them is pulled into circular arcs. The pull is referred to as surface tension of the liquid. Surface tension exists uniformly in all directions. The forces affect the shape and motion of liquids that have open surfaces. Tension forces can be understood regarding forces that occur between the molecules. Repulsion occurs in molecules when they are close but attract when they are far from each other. Inside the liquid, molecules are close to each other. Thus, there are slight repulsions. Molecules at the surface of the liquid are some distance ...

Identification of mystery microbe based on its morphology and biochemical properties

The experiment was conducted to detect the species of a given mystery microbe. The microbe was subjected to a battery of tests in order to identify its physical and biochemical characteristics. Based on the tests, different possible microbe species were eliminated to finally arrive at the right conclusion. The possible microbes included Escherichia coli, Providencia alcalifaciens, Enterobacter aerogenes, Staphylococcus epidermidis, Klebsiella pneumonia, Micrococcus luteus, Serratia marcescens, Mycobacterium smegmatis, Sarcina aurantiaca, Pseudomonas aeruginosa and Bacillus licheniformis.
The first test conducted was to detect the Gram staining properties of the given microbe. This helped in identifying whether the given microbe had a thin ...

Qualitative Research

Introduction
The field of social sciences is primarily concerned with making sense of the world around us. The question of how to study the social world, however, unleashes a number of intense philosophical debates. These debates chiefly revolve around ‘ontological’ issues, denoting ‘what is there to know about the world’. Ontological debates concern themselves with questions about whether the social world contains truths independent of human observation or whether it is human interpretation that gives meaning to phenomena. Hidden in this debate is the tension between qualitative and quantitative research methods and the tension over the use of numbers ...

UNKNOWN #16

SUMMER 2013
INTRODUCTION
Purpose
The purpose of the lab is to separate characterize and identify microbes from unknown mixed culture using the morphological and biochemical methods.

Theory

The process of identifying bacteria is a systematic and careful process which uses various techniques to narrow down the bacteria types which are present in an unknown culture of bacteria. This process produces advantages for many factors of research of microorganisms and assists in the proper treatment of patients (Aneja 10). Several tests were performed to give the fermentation abilities, availability of specific enzymes and specific biochemical reactions.

MATERIALS AND METHODS
