Low interfacial tensions are one of the most important mechanisms relating to surfactant. Surfactant loss due to adsorption on the rock surfaces weakens the effectiveness of the chemical injected slurry, in reducing oil-water interfacial tension (IFT) and renders the process uneconomical. Surfactant flooding is enhanced oil recovery method (EOR) adopted in partially depleted oil reservoirs. However, surfactant adsorption can occur reducing the efficiency of EOR methods used. This work studied the influence of NaCl on anionic surfactant adsorption on sandstone.

Job satisfaction is a positive feeling of fulfillment that a faculty derives from their job. It is an attitude which has an outcome in the form of three dimensions, namely specific job factors, individual feature and having a group relationship outside the work environment. It is multi-dimensional concept and most crucial issues of work and organizational psychology. The study represents the various factors or issues which obstruct in job satisfaction among the academic staff/faculty of some colleges in Patna.

Fortaleza is currently a large metropolis located in northeastern Brazil, the city goes through a constant demographic growth and significant increase of the local vehicular fleet. Currently, public policies for urban mobility in the city are being developed, such as encouraging the use of bicycles in cycle lanes, however these cycle-lanes are located in major high traffic routes in the city.

It is a well-known fact that availability of organic manures are very much limited in the present day agriculture but demand for organic and inorganic nutrient supply to the soils ever growing due to intensive cropping systems. Therefore, the application of nutrients needs to be increased to keep the soil fertile and to make agriculture sustainable, but the cost of inorganic fertilizers escalating day by day making any farming is expensive.

Lacunae in English and Ukrainian as rare words make the problem of Translation Studies, Lacunology. The Lacunology as a new linguistic discipline which deals with lacunae in language, speech and cognition uses the general methodology of tertium comparationis and counting tools to differentiate the endoscopes of the linguistic lacunicon. A lacuna can be interpreted as a hapax in the contrasted discourses and corpus studies.

This paper neatly analyses the artistic skill of Nathaniel Hawthorne in projecting ‘sin’ and ‘guilt’ as common human experiences in life and how it gets beautifully reflected in his novel The Scarlet Letter. It attempts to show how a sense of guilt is awakened either by the violation of a religious edict or some moral law and ‘sin’ is pictured as an offence against the will of God, an act which undermines the entire humanity at all levels possible, bringing home the point that the will of man is the cause of sin.

The purpose of this work was to understand what factors led to the development of the strategy for positioning the Cafés do Brazil brand in the market and to outline a profile of the difficulties to be faced for the institutionalization of the program. It relied on a documentary analysis and literature review to make the inferences. It was observed that the long period of regulation of the chain formed a productive culture focused on quantity forming a producer identity of a single type of coffee, “Cafés Tipo Santos”, demanding an effort to reposition the Brazilian image in the market.

The pace of technological development in educational setting is on the increase in Kenya. The literature is replete with studies indicating that Computer Based Instructional programs enhance students learning outcomes. With the introduction of e-learning in Kenyan schools now at the pilot stage, there is need to develop computer-based programs in the area of mathematics where little or no studies have been done.

In the present pharmaceutical are the science which treat in detail medicinal, pharmacognosy and related product of drug obtained from plant, animal and mineral origins. In short, it is an study crude drugs from natural sources treated scientifically and it encompasses the knowledge of the history, distribution, cultivation, collection, processing for market and preservation, the study of sensory, physical, chemical, and structural characters and the uses of crud drugs. The aim to study of some crude drug in Chhattisgarh region like Ginger, Ajwain, and Black paper.

Ecological indicators have pervasive appeal to scientists, environmental managers and general public at large. They have long been used to detect changes in nature, but scientific maturation in indicator development has occurred mainly in the past twenty years. Currently, indicators are primarily used to assess condition of the environment, as early-warning signals of ecological problems. The present survey reveals the presence of diverse diatom communities in three lakes consisting of 9 different genera and 15 species.
