Distributional Pattern of Blue-green algae in Tezpur Sub-Division of Sonitpur district in the state of Assam
Dr. S.U. Ahmed A.D.P. College, Nagaon (Assam)

Altogether 115 soil samples were collected from different rice-fields of 15 Agricultural circles and 63 BGA isolates were recorded. The isolates belonged to 43 nos. of different strains of 15 genera. Out of the genera, Nostoc and Anabaena were found to be dominant and widely distributed. Key words : Cyanobacteria, distribution, rice field soils of Tezpur sub-division.

Antioxidants in plants: a review
Mousmi Saikia, Department of Herbal Science and Technology

Two-thirds of the world’s plant species have medicinal value; in particular, many medicinal plants have great antioxidant potential. Antioxidants reduce the oxidative stress in cells and are therefore useful in the treatment of many human diseases, including cancer, cardiovascular diseases and inflammatory diseases. This paper reviews the antioxidant constituents of the plant material that act as radical scavengers, and evaluation methods of antioxidant activities.Keywords: Antioxidants; Oxidative stress; Reactive oxygen species; Antioxidant activity; Plants

Application of GIS and GPS in Vector Born Disease Mapping: Paradigm shift in geographical ideas
Prasanta Kumar Gogoi, Assistant Prof.Department of Geography

This article is about recent technological development of geographical studies to discourse disease pattern mapping in a branch of Geography known as Medical Geography. Application of GPS and GIS on dieses surveillance and data visualization has been capable of planning, monitoring, analysis and management of health system. In epidemiology- (.Epidemiology is the study (or the science of the study) of the patterns, causes, and effects of health and disease conditions in defined populations)- GIS aids in visualizing and analyzing geographic distribution of disease with respect to time and space which would have been more difficult and impossible to perform in other way The distribution of vector born disease cases was presented on vector born disease density maps. In the present work dieses data of Assam have been taken into considered and mapping is made. Climatic data i.e. rainfall and temperature data are also used for this study. District boundary maps were digitized with the help of ARC GIS-9.3 software. Disease incidence report from different years is used for this study. The data was collected from District Malaria Office, and the census data of 2011 was used for this study. The important types of vector born disease (VBD) highlighted in this study are Malaria, Dengue Keywords: GIS, Remote Sensing, GPS, VBD, etc.

Role of Pupil -Teacher Ratio in determining GER, NER and Dropout rates in Assam: a Cross Sectional Analysis
Arati Bharali, Assistant Professor Dept of Economics A.D.P. College,

With the emergence of the new endogenous growth theory in economic literature, human resource has come to be recognized as one of the most important factors of economic development. Universalisation of the education can ensure the human resource development in the society. Out of all the levels of education elementary education constitutes the basis on which the super-structure of the education system is constructed. Among various institutional and non institutional factors affecting the enrolment and dropout rates of students in elementary education,, pupil teacher ratio (PTR) plays an important role. Though in case of new enrolment of students PTR is not playing a vital role in Assam, yet PTR proofs to be a more significant factor for upper primary schools in sinking dropout rates in Assam. Other factors remaining constant an enrolment of new children in upper primary schools by two numbers increases the dropout rate of existing students by one in Assam.Key word: PTR, GER, NER, dropout rate

Microcrystalline quartz phases in glassy matrix of fulgurites
Bhaskar J. Saikia and Rashmi Rekha Borah, Department of Physics
We report here the microcrystalline silicon phases of natural fulgurites of Garuamukh and Kimin. Herein the characterization of the microcrystalline quartz in fulgurites by Fourier transform infrared (FTIR) spectroscopy, Fourier transform Raman (FTR) spectroscopy, electron microprobe (EPMA) analyses, Scanning electron microscopic (SEM) analyses, X-ray diffraction (XRD) and X-ray fluorescence (XRF) methods. The spectroscopic analysis exhibits microcrystalline quartz in the basic component of the fulgurite samples. The present study has significant implications in understanding the thermodynamic properties of naturally occurring glasses, which are formed by shock metamorphism.Key words: Glasses, microcrystalline quartz, fulgurites

Development of a country depends on the education of its people. It is this education with which the population can be transformed into human resources. Human resource development is now accepted as a major factor that explains the differential performance in economic and social spheres of the country. In this regard, Technical Education plays a vital role in human resource development of the country by creating skilled manpower, enhancing industrial productivity and improving the quality of life. Technical education is indeed the very foundation of a society which brings economic wealth, social prosperity and political stability. The Engineering College teachers play a vital role in this respect. Therefore their job satisfaction, along with high quality of output is necessary for these educational institutions. So it was felt that the present study would be proper to carry out a survey on job-satisfaction of Engineering College teachers in relation to age, sex, faculty and teaching experience of the teachers in their respective institutions.
