    A study was conducted to assess the cytogenetic changes in an air breathing fish, Channa punctatus subjected to the polluted water of River Cooum. A control group of fish was maintained without any treatment. The fishes were exposed to Cooum water as test samples for 96 hours. The opercular movements were counted at an interval of 1 hour, four times a day for both the control and experimental. The tissues of gill and kidney were then subjected for the study of chromosomal aberration. It was found that the fishes which were exposed to Cooum water showed a decreasing rate of opercular movements as compared to the fishes exposed to tap water. Several structural chromosomal aberrations such as chromatid breaks and gaps, fragments, endoreduplication, ploidy were observed in the fishes subjected to Cooum water in comparison to the Control fishes thus indicating induced mutation in fishes subjected to Cooum water.

    The slum dwelling women’s are not only economically and socially backward but also a neglected section among the society. The environmental conditions of the slum area affect the health status of the slum dwellers automatically. But there are also other factors that controlled the health status. Women do not get proper food four times. They consume cheap prices low calorie food. There are several matters like early age of marriage, early age of pregnancy, given birth to many children’s, small gap between pregnancies etc. which affect their health a lot. On the basis of data obtained from the selected slums of the Dankuni Municipality area, it may be said that, in the area 40.90%women are mother of more than three children and 54.5% mother gave birth to their first child before 20 years of their age. They also don’t get proper pre natal and post natal care. The place of delivery was not always safe. As the level of education is very low the standard of health awareness is also very low in the area.

    The effects of cycloheximide on the changes in activity of glutamate dehydrogenase-NADH dependent (NADH-GDH) and NAD+-dependent (NAD+-GDH), and glutamine synthetase (GS) were studied during the senescence of tomato seedlings in the presence or absence of cadmium. The GDH and GS1 enzymes seemed to be synthesized at the presence of cadmium. Cycloheximide-treated leaves and roots showed an increase in the expression immunostaining intensity of mRNA band gdh and gs1, suggesting an increase in neosynthesis of enzymes and genes activation. The rate of synthesis of GDH was clearly higher than that of its degradation. Cycloheximide (CHX) delayed the protein degradation processes in the cadmium stress conditions. Cycloheximide treatments produced lower gs1 and gs2 enzyme levels than their respective controls especially in leaves. However, the enzyme activity was lower in cycloheximide treated leaves and roots than in the controls. The results are discussed with reference to the requirement for protein synthesis in the cadmium stress conditions.

    This study examined the nature of causality, the impact and relationship between foreign direct investment (FDI), export, and economic growth in Nigeria. Granger causality analysis was used to test the hypotheses causal link between foreign direct investment and economic growth; export and economic growth, while, correlation analysis and Ordinary Least Square (OLS) were used to determine the relationship and the significant effect of FDI and export on economic growth. Our data were extracted from Central Bank of Nigeria (CBN) for a period of 29 years (1981-2010) both years inclusive. After testing for stationarity of the time series, the study revealed no directional-causality between FDI and GDP as well as export and GDP. However, there are evidence of positive relationship between FDI, export and GDP as well as a significant effect of export on GDP. Given the lack of non-directional causality between FDI, export and GDP, Nigerian government should encourage domestic investments through prudent fiscal and monetary policies geared towards achieving economic growth that will attract FDI and encourage exports.

    This study focused on determination of haemoglobin levels in blood of female geophagists and identification of helminth ova in geophagic materials as a possible route for transmission of helminth infections amongst non-pregnant female geophagists. Sixty eight non-pregnant female geophagists, between the ages of 18 and 49 and 5 non-pregnant women between the ages of 18 and 45 (control group) were recruited for the study. Of the 68 non-pregnant female geophagists that were enrolled for the study, 9% of the women were diagnosed of severe anaemia, 35% were anaemic and 56% were normal. All the women in the control group had their haemoglobin levels within the reference range and were normal. An ovum similar to Ascaris lumbricoides ovum was detected in one of the geophagic material. Decreased haemoglobin level may be due to geophagy and poor availability of iron supplements in food. This study suggests that geophagy is associated with anaemia, but could not be a probable mode for transmission of geohelminth infections in this locality.

    The effect of batch co-digestion of the wastes emanating from ethanol production process with some animal and plant wastes on the biogas yield was studied. The wastes from the processing of some starch feedstock and from their fermentation wort were utilized for the biogas production studies. The wastes constituted: (i) process wastes from starch extraction (ET) and (ii) fermentation wort (ETP). They were studied alone (ET-A) and (ETP-A) and in combination with some animal wastes (cow dung (CD) and swine dung (SD) and plant wastes (field grass (FG) and glycerol (GL). The biogas production capabilities of the wastes were in terms of (i) biogas yields (ii) onset of gas flammability and (iii) effective retention time. This was carried out for a retention period of 45 days under ambient mesophilic temperature range of 23oC – 38oC and slurry temperature of 38oC to 48oC using 1 liter micro-digesters under anaerobic digestion. Data analysis was carried out using one way analysis of variance (ANOVA). The results of the biogas production showed that the ET-SD had the highest cumulative biogas yield of 3,800.01 ml/kg slurry and average gas yield of 84.4447± 58.6707 ml/kg slurry while the ETP–A had the least cumulative biogas yield of 677.70 ml/kg slurry and average biogas yield of 15.0602± 6.7644 ml/kg slurry. The onset of gas flammability for the ET-SD and ET-CD were on the 6th day (lag period of 5 days), ETP–FG-GL (13 days) while the ETP–A and ETP-FG did not combust throughout the retention period. By the 45th day, all the other variants were still producing gas whereas the ETP-A and ETP–FG had minimal gas production. General results for the biogas indicate that the processing wastes from the bioethanol are better utilized in combination with animal wastes and with glycerol. These are expected to provide effective waste management system.

    Biogas production from the pure wastes emanating from ethanol production process was studied. The wastes from the processing of some starch feedstock and from their fermentation wort were utilized for the biogas production studies. The wastes constituted: (i) process wastes from starch extraction (ET) and (ii) fermentation wort (ETP). They were studied alone as ET-A and ETP-A. The biogas production capabilities of the wastes were in terms of (i) biogas yields (ii) onset of gas flammability and (iii) effective retention time. This was carried out for a retention period of 45 days under ambient mesophilic temperature range of 23oC – 38oC and slurry temperature of 38oC to 48oC using 1 liter micro-digesters under anaerobic digestion. Physicochemical characterization was carried on the wastes, while microbial analysis was carried out on the waste slurries. Data analysis was carried out using one way analysis of variance (ANOVA). The results of the biogas production showed that the ET-A had a significantly higher cumulative biogas yield of 2,355.49 ml/kg slurry and average gas yield of 52.34±24.23 ml/kg slurry than the ETP–A with a lower cumulative biogas yield of 677.70 ml/kg slurry and average biogas yield of 15.0602± 6.7644 ml/kg slurry (p≤ 0.05). The onset of gas flammability for the ET-A was on the 9th day (lag period of 8 days), whereas ETP–A did not combust throughout the retention period. By the 45th day, both waste variants had minimal gas production. General results for the biogas indicate that the wastes from the processing of starch are better than those from fermentation wort. Their use is expected to provide effective waste management.

    The debate in economics whether financial development causes economic growth or whether it is a consequence of increase in economic activity seems unending. This paper examined the effect as well as the causal relationship between financial sector development and economic growth in Nigeria. This study focused on two focal variables, depth of the financial sector (M2/GDP) ratio of broad money stock to GDP and level of financial intermediation ratio of private sector credit to the GDP PC/GDP. Ensuring data stationarity using Phillips-Perron test permitted OLS and Granger causality to ascertain relationships, effects and causal relationship. Findings suggest positive long run relationship between government consumption and trade openness while the measures of financial development show negative relationships with economic growth. The outstanding results are true for the two major indicators we used M2/GDP and PC/GDP to capture the development of the financial sector, showing that they actually deepen the financial sector but failed to cause economic growth in Nigeria.

    This study examined the impact of indirect material inventory on the profitability of brewery companies in Nigeria. A sample of two brewery companies listed on the Nigeria stock exchange was used for this study. Regression analysis was applied to annual data sourced from annual report and accounts of the sampled companies for the period 1989-2008. The result indicates that indirect material inventory has significant influence on the profitability of Nigeria brewery Plc and Aggregate Company. It also shows that indirect material has insignificant influence on the profitability of Guinness Nig. Plc. The findings confirm that there is a significant relationship between profitability and indirect material inventory in line with the previous studies. This implies that the brewery companies in Nigeria should ensure adequate use of indirect material inventory as they contribute to the efficient functioning of the production machinery.

    The opportunistic and ubiquitous Aeromonas spp., is receiving growing importance since its implication in a wide spectrum of human diseases few decades ago. The enteric pathogen A.hydorphila, is the most commonly associated pathogen with acute diarrhoea, with a similar prevalence world-wide. While the host susceptibility to the disease depends on various risk factors that includes food and water source contaminations, the myriad of virulence factors- Haemolyin, exotoxins etc., craft the complex pathogenicity of A.hydrophila and thus, extensive studies on this bacteria is imperative, especially in developing nations were hygiene measure controls are often neglected. In the present case-control study, PCR was employed to screen two extensively investigated A.hydrophila virulence determinants-aerA and hlyA genes- in clinical bacterial isolates to ascertain the bacterial strain’s pathogenicity in acute diarrhoea from the chosen geographical region. 107 (20.89%) out of 512 acute diarrhoeal patients screened harboured the enteric pathogen, A. hydrophila, while the asymptomatic control subjects (n=200) showed no faecal carriage of this micro-organism. Consistent with previous reports the clinical A.hydrophila isolates screened carried the aerA+, hlyA+, aerA+ hlyA+-virulent genotypes (albeit at varying frequencies) ascertaining the role of the two toxins –Haemolysin (HlyA) and Aerolysin (AerA)-in influencing the pathogenesis of acute diarrhoea in Southern Chennai (India).

    This paper has identified projects as the ‘cutting edge” of development and they represent important and tangible symbols of sustainable change and modernization in an economy. The objectives of this paper include to: explore the concept “project” and it’s cycle; identify the socio-political factors that negatively affects project planning through implementation in Nigeria; highlight tools that facilitates effective project planning, management and implementation; and proffer general recommendations for the effective and efficient planning and implementation of projects in Nigeria. This study employed exploratory and qualitative research methods as we did not test any model in a statistical sense. Data was gathered from multiple sources, including formal interviews, public documents, and the internet. However, there is a strong reliance on interviews because rich insights and contextual information was sought from the key informants. The findings revealed that numerous factors which include poor or no project appraisal; top management lapses; defective contract agreements and awards; and gross failure to apply project management techniques; contracts for projects are awarded without adequate project planning which includes the costing and scheduling as well as the method for successful implementation; a mismatch often exists between project design and objectives on the one hand, and the implementation capacity of the agency or organization or ministry on the other; existence of defective control system, and in some cases, the system of monitoring and evaluation may be completely lacking; where projects are awarded on political considerations little or no attention is given to the recommendations of project appraisals, assuming that such specific studies were undertaken; budgetary constraints occur frequently given the short tenure of governments, reordering of priorities or diversion of fund as time progresses have been identified to impact negatively on project planning through execution in Nigeria.

    The non-oil sector in Nigeria is so disarticulated while it’s sectoral linkage to the economy are so weak. Oil and gas dominate national output while the other manufacturing and production sectors that drives export in the economy is decidedly so small in terms of share of gross output, contribution to economic growth, foreign exchange earnings, government revenues and most importantly, employment generation. Descriptive statistics were applied to time series data spanning a period from 1961 to 2010 after testing for stationary to describe the performances of this sector in terms of revenue and contribution to GDP growth. Correlation and regression analysis were applied to highlight the relationship between GDP and certain identified non-oil sector variables and to ascertain the significant effect of these variables on economic growth. Findings reveal the non-oil sector in Nigeria is so insignificant that it contributes insignificantly to Nigeria’s total federally collected revenue and economic growth.

    Given the important contributions of the brewerysector to the Nigerian economy, this research deems it necessary to evaluate the effect of raw materials inventory management on the profitability of brewery firms in Nigeria. A cross sectional data from 1989 to 2008 was gathered for the analysis from the annual reportsof the sampled brewery firms. Measures of profitability were examined and related toproxies for raw materials inventory management by brewers. The Ordinary Least Squares (OLS) stated in the form of a multipleregression model was applied in the analysis. The study revealed that the focal variable raw materials inventory management designed to capture the effect of efficient management of raw material inventory by a company on it’s profitabilityis significantly strong and positive and impacts on the profitability of the brewery firms in Nigeria. Therefore, efficient management of raw material inventory is a majorfactor to be contained with by Nigerian brewers in enhancing or boosting their profitability.

    Forest provides a means of livelihood for rural communities in the developing countries. It plays a vital role in global food security, providing food, fodder, fuel and medicine. Throughout the developing world, women make a significant contribution to forestry. The present paper attempts to study the organic linkages between women and forest resources. Indigenous women’s knowledge plays an important role in the management, conservation and sustainable use of forest resources. They are the collector, and direct user of the forest resources to sustain livelihood, due to illiteracy, poverty, ill-skilled in technical knowledge and lack of control over land and other resources, they are less benefitted from natural resources from economic perspectives but they are still at underprivileged position in environmental decisions at households as well as society level.

    The present study is based on the synthesis of silver nanoparticles (Ag NPs) by “cleaner and greener” approach for environmental clean-up. Our way of Green synthesis methods include hydrolysis of protein solid waste, extraction of bio molecule, Synthesis of silver nanoparticle and anti-bacterial application. Proteolysis bacteria isolated from marine environment was identified as Bacillus sp. CJ2 and used for the hydrolysis of protein solid waste, which resulted in bio-molecule rich broth production. From the bio-molecule rich broth, enzymes were separated out by ammonium sulphate precipitation method. Enzyme molecular weight was found to be around 60KDa. Later remaining bio-molecule was utilized for synthesis of silver nanoparticle. Synthesized Nano-particle was found to be stable, which shows the presence of both reducing and stabilizing agent in bio-molecule. The mechanism of the Ag NP bactericidal activity is discussed in terms of Ag NP interaction with the cell membranes of bacteria. The property was found to be positive for the sewage water isolated E coli.

    Heavy metals were determined from waste dumpsites in Gboko metropolis, Benue state, Nigeria. The mean pH values of the soil samples were found to be 7.70 and 7.15 for Gboko North and South respectively. The analysis of heavy metals indicate that samples from Gboko North show mean concentrations (mg/kg) of heavy metals as; Pb (0.966), Ni (0.514), Cd (0.298), Al (0.223), Cr (0.092), As (0.051). Samples from Gboko South indicate mean levels of heavy metals as follows; (1.300mg/kg), (0.377 mg/kg), (0.191mg/kg), (0.009mg/kg), (0.18mg/kg), (0.042mg /kg) for Pb, Al, Cr, Ni, As, and Cd respectively. In Nutshell, Ni, and Cd were found to be relatively higher in Gboko north than Gboko south. On the other hand, the levels of Pb, Cr, Al, and As were higher in Gboko South than Gboko North. All the heavy Metals were within the WHO acceptable limits except Cd and Cr which were slightly above these limits in some dumpsites. Although Heavy metal concentration in refuse dumpsites of Gboko metropolis may not appear to pose a very serious environmental problem at the moment, continuous accumulation of these metals in Gboko metropolis may result into some health threat to human and the environment in future.

    Diversity as “difference, unlikeness, variety and multiformity. Exploration of assumptions, beliefs and attitudes concerning diversity would provide us insights on the preferences of the members of an organization for similarities or differences, homogeneity or heterogeneity, otherness or inclusion. Of course, it is not always necessary that individuals and groups look at them in a dichotomous way and instead feel comfortable with both. The purpose is to explore the existing notions of members of an organizations and examine whether they consider diversity as adversity or advantage. It is possible to hold three views about people: all are alike, some are alike, or not two are alike. The purpose is to explore what is our view and what is the basis governing our own assumptions beliefs and attitudes so that, if need be, we modify them to overcome biases, prejudices and stereotyping.

    Forest Communities (about 28% of Kenya’s population) represent a critical section of Kenya’s overall population. Many of these people interact on a daily basis with forest resources around them. The knowledge about their perceptions and attitudes pertaining to forest resources may make it possible to contextualize their influences on sustainable management of forest resources. The missing link in this paradigm could be the inadequate or little levels of incorporation of community based forest management strategies in planning for sustainable utilization of forest resources. The incorporation of local community’s perception in forest management could therefore be fundamental in reversing the downward trends of forest loss. It is assumed that people are a product of their environment, therefore it can be insinuated that the perception of forest utilization by the forest communities is based on their interactions, traditions, values and attitudes. This paper therefore examines the perceptions of the Kalenjin community living around Nandi Hills Forests (NHFs) and how their perceptions have influenced the utilization practices of NHFs. The study investigates cultural constructs that have had a bearing on the perception and use of these forests and the role of traditional and religious practices.

    Due to increased pollution activities in the world today, it is important to embrace the sustainable development principle. The principle of sustainable development is that the integration of economic, social and environmental concerns. Sustainable development recognizes that the economy and the environment are closely interrelated. Much economic activity uses up materials and resources, including forests and minerals, and creates waste products. Yet many economic activities, including agriculture, fishing and tourism, are also dependent on a healthy environment. The general objective of this study was to assess the con¬tribution of the community as it formed social groups to combat the pollution problem in Thika Municipality, Kenya. To achieve the objectives of this study, both quantitative and qualitative research methodologies were used. The qualitative phase consisted of face-to-face interviews/administered questionnaires. In addition, the qualitative phases consisted of several focus group discussions and in-depth interviews to selected members of the community. In essence, the qualitative phase was used to provide more insights and findings obtained from the quantitative phase. In order to arrive at the targeted sample of 60 house-holds, the researcher visited the community. Among the major findings, air, water and solid waste pollution were adversely mentioned as the problem the community failed to quantify on pollution awareness. On the other hand, noise pollution was not considered to be harmful in any way to the community. This was due to the limited knowledge of the community. The major effects of pollution enumerated, included the destruction of buildings and other structures.

    The IR vibrational spectra of the ceramic test samples were recorded and discussed which servesas the molecular fingerprint to give proof of identity without recourse to any other analytical method and yields basic information on the changes in the interatomic bonding. The possible use of ceramic rejects in the clayey body draws particular attention. The IR assignments of the raw samples are almost alike despite the different compositions and show stretching and bending modes of kaolinite at different absorption frequencies of 3694 cm-1 and 913 cm-1 respectively. The structural changes take place at different calcination temperatures which are interpreted in depth.An analysis of the mineralogical composition during a firing cycle up to 1200 0C has demonstrated that they possess satisfactory characteristics for the desired applications in the ceramic industry.

    Waste management is one of the most common and challenging problems in the world. The steel making industry has generated substantial solid waste. Mild steel slag is a residue obtained in steel making operation. This paper deals with the implementation of mild steel slag an effective replacement for stone or aggregate. Mild steel slag which is considered as the solid waste pollutant can be used for road construction, clinker raw materials, filling materials, etc. In this work, mild steel slag is used as replacement for aggregate or stone, which has highest content in concrete mixture. This method can be implemented for producing hollow blocks, solid blocks, paver blocks, concrete structures, etc. Accordingly, advantages can be achieved by using mild steel slag instead of natural aggregates. This will also encourage other researchers to find another field of using mild steel slag.

    In the area of Sexual and Reproductive health, the onset of reproductive roles does not entitle the young women to their maternal and child health services or family planning services unless they are married and have children less than five years. High rates of Urbanization in developing countries have produced innumerable slums and squatters with very poor living conditions. The Global disease burden of Reproductive Tract Infections (RTIs), including Sexually Transmitted Infections (STIs), is a major health concern. Research evidences till show that only a few studies have been sophisticated on gynecological morbidity. Similarly the studies that deal with obstetric morbidity are very limited. Hence it is necessary to examine the determinants of RTIs in relation with socio economic and demographic characteristics by making use of appropriate framework. The prevalence of RTIs mainly depends upon the socio economic and demographic status of the people. Such studies will enable policy makers, administrators, health professionals and the academic community to understand the relation between the prevalence of RTIs and various socio economic and demographic characteristics of women. With this background an investigation has been made in this study to analyze the linkages of socio economic and demographic variables of women and the prevalence of RTIs. The association between the socio economic and demographic characteristics and the symptoms of reproductive morbidity has been statistically verified in the following section with the use of Analysis of variance and Chi-Square test. Some Policy measures have also been suggested.

    Objective: The objective of our study is to develop an expert system for Management of Head Injury Patients (MHIP) to automate treatment planning support for severe head injury patients. Methods: A study was conducted among the Head injury Patients of Government General Hospital (GGH), Chennai, India. The necessary information were recorded and the risk factors were identified by various multivariate statistical models using SPSS package, with all these information together with the opinion of the Neurosurgeon on important clinical factors an Expert system MHIP has been developed. Results: Our study reveals that out of 801 head injury cases, 261 were severe head injury cases (GCS ≤8). It was alarming to observe that around 60% of the severe head injury cases were dead. Risk of Persistent Vegetative State /Death is 2 (95% CI = 1.18 - 4.33) times more in older people than the younger ones. The cases with abnormal respiratory rate had 5 (95% CI = 2.54 - 8.40) times more chances for death than cases with normal respiratory rate of 10-24/min. Thus the older age (P=0.001), abnormal respiratory rate (P=0.003) and lower GCS (P=0.008) were found to be consistent risk factors and significantly associated with the mortality of severe head injury patients. Conclusion: From the perspective of patients’ well being, Persons trained in trauma care in the rich industrialized countries depend a great deal on expensive, sophisticated diagnostic and curative equipment and materials. It will not be possible for most hospital in Low income Countries to obtain and stock such equipment and materials. Therefore an Expert system MHIP, developed in our study would help the neurosurgeon to a greater extent in identifying the patients, whose life can be saved, and which are cost-effective and feasible in such Institutions.

    Carbamate insecticide, carbaryl (1-naphthyl-Nmethylcarbamate), is highly toxic with a wide range of activity and known to be metabolized by microorganisms belonging to a variety of bacterial genera by interacting with different components. To evaluate its toxicity, the present study was undertaken by using increasing concentrations of carbaryl (10-8 to 10-2M) and evaluated for its toxicity to Escherichia coli with emphasis on enzyme assays such as such as activities of amylase, protease, phosphatase, superoxide dismutase (SOD), catalase and peroxidase assay and was further compared to the soil isolate- Pseudomonas aeruginosa at a given periods of 24 to 72 hrs respectively. The results indicated that carbaryl treated groups exhibited a significant (P ≤ 0.05) increase in the enzyme activities of Escherichia coli and Pseudomonas aeruginosa with an increase in dose and duration when compared to the controls. While, in assessment with its free corresponding, the activity was less in immobilized Escherichia coli cells enlightening that immobilized system is less responsive to carbaryl. Present study suggested that carbaryl is a toxicant affecting the synthesis of enzyme activities in of Escherichia coli and Pseudomonas aeruginosa and alteration in these enzymes occurs as an adaptive mechanism to chemical stress or participation of these enzymes in the protection against ROS, thereby impairing the physiological and metabolic activities of the cell.

    The purpose of this study was to investigate the effect of agro-waste substrates like banana peel powder and coir powder at varying environmental parameters of pH (4-9) and temperature (20-50ºC) on the cellulase production by Trichoderma reesei. The enzyme production was measured by the amount of glucose liberated in IU/ml by using dinitrosalicylic acid method. The substrates were pretreated with alkaline pretreatment and autoclaved. The maximum activity of the enzyme was assayed at varying pH with temperatures being constant and varying temperatures with pH being constant. The maximum activity of the enzyme was assayed at varying pH was documented at pH 6 for banana peel powder (0.57±0.03 IU ml-1) and coir powder (0.42±0.02) and the highest activity of the enzyme at varying temperature was recorded at 40ºC for both banana peel powder (0.65±0.02) and coir powder (0.47±0.002) after 144h of incubation. Thus the maximum amount of the enzyme was reported at pH 6 and temperature 40 ºC for both banana peel powder and coir powder. Moreover among the two substrates used for the production of cellulases by Trichoderma reesei banana peel powder exhibited maximum enzyme activity at 1.5% concentration (0.69±0.02 IU/ml) than coir powder as substrate.

    Lichen has a remarkable property of absorbing inorganic cations from the natural substrates on which they grow in amounts which are in excess of any expected requirements. We examined 20 sexicolous lichens which are known to fix metal ions found in Hilly areas of Himachal Pradesh of India for their metal fixation property. The mechanism by which Lichens take up cations is of considerable interest. Touminen (1967) proposed that alkali and alkaline metal ion uptake involved a simple ion-exchange process, which can occur inside the thallus cells of lichen by Intracellular ion-exchange mechanism of the proteins metallothioneins. Out of 20 protein samples 16 samples were found to have bound metal ions in considerable amount. These results enabled us to conclude about a similar mechanism of metal fixation in nearly all lichenic species possessing this property.

    Today, India has been facing two most vital problems which are directly related to agriculture, the first one is to meet the swelling demand for food and other agricultural products, and the second is enervating the widespread poverty in rural areas by the ever increasing population. The good performance in agriculture can diminish levels of rural poverty and meet increasing demand of agricultural products (Ahluwalia, 1978). Agricultural productivity is a measure of the efficiency with which inputs are used in agriculture to produce an output. When a given combination of inputs produces a maximum output, the productivity is said to be at its maximum. The measurement of agricultural productivity enables a comparison of relative performance of farmers between farms, between the types of farming and between geographical regions. The comparison of productivity goes on to the heart of economic performance and can provide the guidance for planning and development decisions (Kravis, 1976). Present study confined to such an analysis of agricultural development in terms of efficiency and productivity of Hugli District, which is one of the agriculturally prosperous district in West Bengal due to the presence of Gangetic fertile alluvial tract, better irrigation facility and high demand of agricultural products in different agro-based industries. Besides measuring the level of efficiency and productivity at block level, an attempt has been made to find out the major controlling factors of overall agricultural system based on PCA analysis. Finally this work concluded to make some suggestions and management plans to enhance the agricultural output in terms of yield as well as money.

    Cloud computing is one of today’s most attractive technology areas due to its many advantages like Highly scalable, on-demand, web-accessed IT resources with major cost / cash and flexibility. Various companies around the world adapting cloud computing as a means to increasing efficiency and reducing cost of their IT services. In this research paper efforts have been made to analyze the use of hybrid cloud computing model with security and scalability in business information system. There are many challenges in using cloud computing. The main challenges are security and because all essential services are generally outsourced to a third party. The outsourcing makes it harder to maintain data integrity and privacy, support data and service availability etc. Using public cloud model only in the business is very risky because of its security reasons and using private cloud only will not solve our purpose because in that case we will not be able to use advantages of public cloud model. To solve these security problems in business information system we can use hybrid cloud computing model where we can use advantages of public cloud and security of private cloud, in which we can elect to store highly sensitive data of the company in the private storage cloud and less sensitive data in public storage cloud. This research paper focused upon the security problems in business information system. Research suggests a hybrid cloud computing model where converging advantages of public cloud and security of private cloud can be used.

    Green gram (Vigna radiate L.) is also known as mung bean or golden bean belongs to the Family Leguminosae. Green gram is a short duration crop and mainly cultivated as a rainfed crop under Rice fallow condition and irrigated crop. The low productivity under rainfed condition is due to soil moisture deficit, uneven rainfall, low soil fertility and poor crop management. To overcome this problem, seed researchers like Henckel as early as 1964 recommended the seed hardening techniques to alleviate the moisture stress condition. The present study will emphasize on the effect of seed hardening using various leaf extract like prosopis, pungam, nochi, neem,umathai, aduthoda, nerium, papaya, bittergourd etc. on seed and seedling characteristics like germination per cent, speed of germination, accumulated speed of germination, mean daily germination, root length, shoot length, seedling length, DMP, SV-I and SV-II of green gram ADT3. From the present study, it could be concluded that green gram seeds should be hardened with 1% prosopis leaf extract for 3 hours @ 1/3 rd volume of solution to enhance the seed and seedling quality characteristics under adverse environment conditions. In addition, green gram seeds may also be hardened with 1% pungam leaf extract to get the similar results.

    Background: Hepatitis B virus (HBV) infection is a vital health problem in blood transfusion throughout the world. A good number of studies in northern Nigeria were amongst people infected with HIV/AIDS; hence information is very scarce on the prevalence of HBV infection among blood donors in Nigeria. Objectives: The necessity for information about this silent killer among these apparent healthy blood donors was the center for this study. Methodology: Hepatitis–B-surface antigen (HBsAg) latex kit was used to determine the prevalence of HBsAg among 370 voluntary blood donors (age 20-60years) in Jos university teaching Hospital, Nigeria. Result: Three hundred and seventy (370) blood donors were screened for HBsAg and 100 (27.0%) were positive. Males recorded 97 (27.3%) while females had 3 (21.4%). Prevalence of HBsAg according to age showed that, age 20-30 years recorded 33.8%, age 31-40 years recorded 27.9%, while ages 41-50 and 51-60 years recorded 14.5% and 9.1% respectively. Routine screening for HBsAg in blood donors is very important because asymptomatic donors may be chronic carriers. Conclusion: The prevalence of 27.0% HBsAg within the study population shows that it is of public health significance.

    Adolescence stage is a period where biological factors are mainly recognized like brain development, increase in height, weight gain, motor skills and hormonal changes in puberty. This is the stage where adolescents’ cognitive development is increased. They are able to memorize many concepts, they become very creative, they reason logically and are very imaginative. Their social development also improves a lot especially in developing relationships with members of opposite sex. Their emotional development changes to aggressive state especially when dealing with adults like their teachers and parents. Adolescence stage is characterized by a lot of adventure on both positive and negative health behaviour and it is the stage which acts as a junction to positive or negative health behaviour. Most of the health behaviours either positive or negative which are experienced in adulthood began in adolescence. The adolescents have little knowledge about health issues and they always imagine that health problems are for old people. This paper seeks to explore some few issues concerning the adolescence stage and it is hoped that all adolescents will benefit from it as well those who work closely with the adolescents.

    IT careers are often characterized by hard work, long hours and tight deadlines. Coupled with these high stressed careers, personality traits like high ambition, a strong sense of time urgency, hostility, distrust and anger could play havoc on the physical and psychological well-being of the professionals. Managing stress by mobilizing and enhancing internal coping strategies and learning and employing appropriate methods of responding to stressful situations are assumed solutions to the ever increasing demands of IT field. Present study was conducted to assess personality types and stress levels of the selected IT professionals and to examine the relation between their personality types and stress levels. Data were collected from 60 IT professionals employed in four computer software organizations at Bangalore. The results showed that half of the selected IT professionals had stress prone Type A personality and on the whole they had moderate stress. It was found that personality type and stress showed a positive and a significant correlation which indicated Type A personality as more prone to stress. Recommendations and suggestions to improve the coping strategies were discussed to enable the IT professionals manage their stress.

    Disease has always been a great topic of concern in aquaculture industry. Antibiotic sensitivity, bacterial resistance is an issue that needs to be considered while treating the disease. Various steps were taken to find out possible alternative methods to minimize the antibiotics use in the aquaculture industry for disease management. Probiotics, feed additive and natural products such as herbals, sea weeds and good management practices in disease control have proposed for better production without having adverse effect. In the present study, five different Vibrio spp. isolated from four different marine fishes Strongylura spp (V1, V5), Sphyraena spp (V2), Lethrinus spp (V3), Carangoides spp (V4) are characterized by Random Amplification of Polymorphic DNA (RAPD) profile. Three primers (TW-3, RBA- 5, OPA-2) were used to distinguish Vibrio spp. by the RAPD profile analysis method. Among three primers RBA-5 showed fewer banding patterns range from 250 bp to 1000 bp. RAPD profiles were clearly distinctive between the five Vibrio isolates (V1-V5). Primer TW-3 and OPA-2 produced greater banding patterns between five Vibrio spp. The antibacterial activities of five important seaweeds namely Sargassum wightii, were screened against five different Vibrio spp isolated from commercially important marine fishes. The zone of inhibition in the crude extract of seaweeds (Sargassum wightii, Caulerpa peltata) was varied from against Vibrio spp. methanol extract of sea weeds shows maximum zone of inhibition against V3 strain and minimum zone of inhibition against V5 strain. The results clearly indicate that the seaweed compounds effectively inhibit the Vibrio spp.
