Abstract

"Programme Evaluation Review Technique" is one of the latest modern technique for the planning, scheduling and controling of complex projects. There is a great scope of using this technique in Forestry Projects. Timber harvesting, includes, a large number of interdependent operations, which are like links of a chain. With the departmentalisation of forest working, logging has become more complicated in recent years. An attempt has been made in this article on the appliciltion of this tool on a simulated timber harvesting project. The project under consideration consist of 59 interdependent activities and the total time of the project is 305 days. The main thrust of this technique i.e. Net work has been drawn to find out the critical path of this project. It is observed that out of 59 activities only 16 activities, are critical. Forest manager should pay maximum attention to this critical activities, to control the progress and to finish the project in target time of 305 days.

Abstract

Context: Often coexisting in developing countries with under-nutrition, obesity is a complex condition, with serious social and psychological dimensions, affecting virtually all ages and socioeconomic groups.

Objective: 1. To find out the prevalence of obesity and faulty weight perception among college going girls of Agra. 2. To compare the actual with perceived weight status and 3. To have an eye on the desired weight status of the study subjects

Material and method:

Study design: Cross sectional study.

Setting: Urban and rural colleges of Agra

Study period: January to June 2009 Sample size: 400 college going girls of 18-24 years.

Study variable: Height, weight, weight perception, desired weight

Statistical Analysis: Percentage, Kappa statistics

Results: The prevalence of overweight and obesity was found to be 18.5%&4.5% respectively. The prevalence of underweight was 31.5%. The prevalence of faulty weight perception was 54.5% and was found to be inclined towards feeling of higher weight. This accounted for the relatively lower prevalence of perceived underweight (13.5%), perceived normal weight (31.8%) and higher prevalence of perceived overweight (54.7%) compared to actual weight status based on body mass index.

Conclusion: The dual burden of underweight and overweight among the college going girls, along with prevailing faulty weight perception, if not corrected in time, may lead to adoption of faulty weight control practices, development of eating disorders, and, above all, may end up in aggravating the already existing high level of under nutrition. The later can have adverse long term impact on the health and well being of the offspring born to these 'would be mothers'.

Abstract

Functional groups and mineral matters in Talcher coal have been identified with the help of FTIR. Oxygen bearing functional group mostly hydroxyl is common in bulk as well as different lithotypes. Minerals such as kaolinite, quartz, goethite etc. have been identified from the spectra. The functional groups data have been used to interpret the conditions of formation of the different lithotypes.

Abstract

This note is aimed at elucidating the relationship between morphology and chemistry of some ferromanganese samples of Central Indian Ocean basin and describing precisely the factors controlling these variations. The samples investigated were dredged from Central Indian Ocean basin at a depth of 4000-5000 m during cruises of SS Fernela (St. F₄ and F₅), SS Scandy Surveyor (St. SS₄, SS₅, SS₆ and SS₈) and RV Sagarkanya (St. SK₈) conducted by the National Institute of Oceanography, Goa. Because of certain restrictions, location of sample details have not been mentioned.

Abstract

Trace element distribution in bulk coal and lithotypes viz. durain, fusain, clarain and vitrain in two coal seams of two geological formations of Karharbari and Barakar from Talcher coalfield, Orissa is reported and compared with world coal trace element data. Karharbari coal (seam I) contains higher concentrations of As, Ba, Ce, Cr, Th, U and W than Barakar coal (seam II). On the contrary, coal from seam II has high concentrations of Be, Eu, Hf, Mo, Sb, Sc, Sm, and Zn. In both the formations, durain and clarain contain maximum trace elements including REE in appreciable concentration where as vitrain shows least trace constituents. Positive correlation of ash with Ba, Cs, La, Hf, Th, Rb and Sc indicates inorganic affinity of these trace elements. However Sb, As, Cr and Co show negative relation with ash explaining their organic affinilty.

Abstract

Talcher coal is non coking and high ash type and presently used for thermal power generation, sponge iron making, cement and chemical industry. Coal beneficiation is being carried out by size reduction followed by washing and gravity separation to reduce the ash content and improve other chemical parameters. Poor washability characteristics of Indian coals in general and Talcher coal in particular and presence of high near gravity materials do not support the conventional washing techniques resulting in below expected quality yield. The role of detailed petrographic studies during processing/benificiation needs special attention in order to improve the quality of coal and competitiveness of the product in the open market.

This paper provides general information on petrogmphic findings of coal from different seams presently exposed in Talcher coalfield in terms of lithotype, maceral, mrcrolithotype, mineral matter and rank (vitrinite reflectance). Importance of lithotype, mineral matter and oxidation characteristics of coals with respect to coal preparation /beneficiation and maceral /microlithotypes in combustion has been discussed in detail.

Abstract

The extent of vaporisation and subsequent condensation of many trace elements during coal combustion is largely dependent upon the mode of occurrence of the trace elements, besides many other parameters. Mode of occurrence of a few important trace elements in coals from Talcher coalfield representing low and high ash type from Karharbari and Barakar Formations is studied by sequential leaching experiments. It is observed that in both the coal samples, Cr and Mn exhibit more affinity towards organic matrix and/or insoluble oxide phases. Pb and Cd are mostly associated with soluble sulphide and oxide minerals. Co is mostly bonded with silicate phases in the coal samples. No definite mode of occurrence is visualised for Ni from the present study, as it is associated more with the residue indicating its association with either organic matrix or insoluble oxide.

Abstract

The study of fish diversity of the river Pilasalunki situated in Phulbani distict, Odisha was attempted during 2012. A total of 23 fish species belonging to 9 families were recorded. Out of the recorded species, 35 per cent are enlisted as vulnerable, 52 per cent as lower risk near threatened category. Maximum number of fish species were collected from slow flow site (31.6%) followed by silty sand beds (17.6%), deep water zone (15.8%), gravel habitat (15.8%), fast flow zone (10.5%) and least in shallow water zone. Shannon diversity index (H') fluctuated from 0.29 to 0.93, Simpson dominance index ranged from 0.14 to 0.52 and Margalef richness fluctuated from 1.38 to 9.65. Bray Curtis cluster analysis recorded 100 per cent similarities within Wallago attu, Labeo dyochilus and Nemacheilus botia (sub cluster-I), Puntius sarana, P. Sophore, and Mystus cavasius (sub cluster-II), Glosogobius giuris and Mastacembalus armatus (sub cluster-III). Correspondence analysis indicated Nemacheilus botia, Labeo dyochilus, Heteropneustes fossilis, Wallago attu, Cirrhinus reba, Glosogobius giuris, Mastacembalus armatus and Mystus cavasius, Channa gachua, Puntius sophore and Puntius sarana congregated distantly from origin suggesting their stock enhancement through conservation measures.
