Low cost surfactants for Wettability alteration studies
Funsho Afolabi and Ebitimi Fakrogha

Surfactants possess the ability to alter rock wettability which will improve oil& gas well productivity, however the cost of chemicals that serve as wettability alteration agent can be a major constraint to exploring the option for improved oil recovery. The goal of this study is to develop a surfactant from locally sourced and readily available reagents at low cost, with favourable potency levels, which can compete with synthetic surfactants. The core sample used for this experiment is...

Adsorption isotherm the herbicide 2-methyl-4-chlorophenoxyacetic acid in watery phase on soil with high contained of...
Pila, A. N., Jorge, M. J., Profeta, M. I., Romero, J. M., Jorge, N. L. and Castro, E. A.

Ground and Surface water contamination by herbicides commonly used in rice cultivation is a matter of current concern in Corrientes regions. The fact that most commercial formulations of herbicides containing the active materials in a form immediately available increases the risk of transmission losses of herbicide applied to the crop and, consequently, the risk of contamination of ground and surface water. In this work we presented the adsorption of the herbicide 2-methyl-4-...

Intra-regional disparity in human welfare in the Nigerian Niger delta: The need for sub-regional integration
ASANI Morufu Afolabi

This paper evaluates the socio-physical and socio-economic improvements oil exploration and production have brought to the oil bearing sub-region relative to non-oil bearing sub-regions of Ondo State in the Nigerian Niger Delta. The aim is to compare the level of development and human welfare in both sub-regions. Ilaje and Edo-Odo (the oil bearing local government areas); and Okitipupa and Irele (two non-oil bearing local government areas) were selected for the study. Sixteen different types...

Material and Method: Relevant information of all the replacement blood donors who had donated whole blood in the department of transfusion medicine, SMHS Hospital, Kashmir from Jan 2000 to Oct 2010 was...

Microwave assisted synthesis of some pyrazoline derivatives as potent anticancer agent: A Review
Dr. Alka Pradhan, Harshita Goyal and Nazish Khan

Heterorcycles have attracted considerable attention in the design of biologically active molecules. The class of pyrozolines possesses a broad spectrum of biological effectiveness including anticancer activities. pyrazoline derivatives is quite stable and has inspired chemists, to utilize pyrazoline fragment in bioactive moieties, to synthesize new pyrazoline derivatives. The past studies of pyrazoline derivative revealed that they are useful in pharmaceutical and agrochemical research....

Identification of information sources influencing the technical inefficiency of crop farmers in Vietnam
Truong Tuan Linh, Teruaki Nanseki and Yosuke Chomei

Vietnam is an agricultural country where rice and maize are the two most important cereal crops. Recently, the proportion of high-tech agricultural products has increased; however, output quality and quantity have not reached the expectations. There are many possible reasons, one of which is that farmers lack skill, experience, and knowledge to receive and generate information sources. This study estimated the technical efficiency levels and identified the information factors that influence...

Mary Esther Cynthia Johnson, Olive Kezia Ruth and Glory Margaret, A.

In the present study 30 Plants i.e. 10-Trees, 12-Shrubs and 8-Herbs growing in various places of Hyderabad city were selected and analysed for certain physiological and bio-chemical parameters, pH of the leaf extract, Leaf Relative Water Content, Ascorbic acid content and Total chlorophyll content. Based on these parameters APTI (Air Pollution Tolerance Index) values were calculated. Plants absorb the air pollutants and they act as natural-sinks, depending on the APTI values the plants are...

Native and synchronous Spectrofluorimetric methods for simultaneous determination of Amlodipine Besylate/Valsartan...
Dr. Taghreed Abd-El-Fattah Mohammed

Blokatens tablets are novel prescription drug that combines amlodipine besylate (AM) with valsartan (VS), were simultaneously determined by two different spectrofluorimetric methods. The first method depend on measurement of native fluorescence intensity of both drugs at ג emission 460nm and 385 nm using ג excitation 390nm and 227nm for AM and VS respectively in water. The second method utilizes synchronous fluorimetric quantitative screening of the emission spectra of AM and VS at 375 and...

Design of energy efficient random access memory circuit using stub series terminated logic i/o standard on 28nm FPGA
Alok Kumar, Gaurav Kumar Sharma, Anjan Kumar, Tarun Agrawal and Vivek Srivastava

This paper is based on the designing of energy efficient memory circuit using various IO standard of SSTL logic family on 28nm (Artix-7) Field Programmable Gate Array (FPGA). We are using Xilinx ISE simulator version 14.2, Verilog hardware description language and Artix-7 FPGA. Six different SSTL IO standard are compared with each other to find the most power efficient among them. The design has been tested for power consumption at different operating frequencies as of Intel processor that...

Growth and characterization of calcium doped barium Tartrate crystal from silica gel
Juliatsahayamary, S. and Jessie Raj, M. B.

In the present investigation, single crystals of Barium calcium tartrate were grown by gel technique using diffusion method. The growth conditions were optimized by varying the parameters such as concentration of the gel, setting time of the gel and concentration of the reactance. The test tubes were used as crystallization vessels while silica gel as a growth media. The grown crystals were characterized by using X-ray diffraction, Scanning electron microscopy, Ultra-Violet visible...

Asish Mandal

Xylan, one of the most abundant products accumulated in soil is degraded by Endo-1, 4-β-xylanase (Endo-β-1, 4-xylan, xylanohydrolase; EC., commonly called xylanase). The enzymes are produced mainly by soil microbes. Xylanases from fungal and bacterial sources have been extensively studied. The characters of soil and the distribution of such potent xylanase-producing bacteria from the adjoining areas of Midnapore town have been focused. Xylanase producing bacteria are isolated on the...

Zootherapy for mankind: an unexplored segment in make in India – A Review
Saurabh Saxena and Shrivastava, S. K.

Historically, plants have been preferred over animals in making of human medicine. Abundant transcripts are available sharing various reasons from spiritual believe to regional cultural diversities in accepting plant products and by-products as human medicines. Thus, huge untapped potential of utilization of animal and animal by-products can be explored in making human medicines. Efforts have been made to understand “Role of Animal and its contribution in Human Medicine” as well as potential...
