Library Assignment - Essay Example All the same, this was never the key source of error. In the year, 1963 Price proceeded to work making use of several data in abstract compendia for the years 1907 to 1960. The study conducted in the years 1907 and 2007 by use of available statistics from several literature databases, Social Science Citation Index (SSCI) and the Science Citation Index (SCI) have indicated findings relating to the Growth rate of scientific publications. Significantly, the intention of the study was to give information regarding the growth and development of Scientific Publications (Garfield, 27). The study is descriptive in that; it gives descriptive data on which the research was based on and also includes the statistical processes used in the description of the population in the study. The findings from the study assist in organization and data description. The variables involved were the data from the traditional scientific publishing. Traditional scientific publishing; publications in peer-reviewed journals, is still considered to be increasing though there are large variance between some sectors. There exist no signs that the growth rate has decreased within the past 50 years. At the same time, publications making use of channels, for instance, open archives, home pages and conference proceedings are reported to be developing at a higher rate. The growth rate for the SCI was compensating a declining section of the traditional scientific literature (Garfield, 29). There also exist some open signs that the compensation by the SCI is generally minimal in a section of the scientific areas with the largest development rate involving engineering and computer sciences. From the reading, it is obvious that the populace being considered are the humans, and this is with respect to how they rate the scientific publications. The common characteristics of this

What is the pH of Soil Essay Example | Topics and Well Written Essays - 250 words

What is the pH of Soil - Essay Example This is determined on a pH scale that ranges from 0 to 14. A substance with pH nearing the scale’s lower end is considered very acidic while those on the upper range would be considered basic or alkaline. The neutral on the scale is at ph 7. Pure rainwater has pH of 5.6 or thereabout, but it changes when it enters the soil depending on the soil’s chemical characteristics. Nutrients such as phosphorous and calcium are more soluble in slight acidity. In this experiment, the objective is to determine the pH of soil sample provided. Just as is the case with rain water, these nutrients can be dissolved in distilled water. When litmus paper is immersed in the clear solution after the soil settles down, acidic soil with pH less than 7 will cause blue litmus paper to turn red while basic soil with pH greater than 7 will cause red litmus paper to turn blue. Neutral soil will have no effect on both red and blue litmus papers. It is crucial to know the pH of soil as crops grow best within a narrow range of pH varying from one crop to another. For example, blueberries grow best at pH 5.5 or lower while potatoes do best at 5.5 to 6.0. The 5.5 to 7.5 range is favorable because it accommodates microorganisms which are important in breaking down organic matter and also provides the necessary condition for nutrient availability (Conklin
