Abstract : In present investigation of anionic (fluoride, chloride, bromide, phosphate and sulphate) change in surface and groundwater due to industrial effluents by ion chromatography technique has been determined in area of Jammu using Ion-chromatograph (IC-850). Surface and groundwater samples were taken before and after discharge of industrial effluents. All required standards for calibration and all the samples (water as well as industrial effluents) have been prepared by using ultra pure water obtained from M Millipore. Both the peak height (PH) and peak area (PA) were used to assess the IC signals. All the peaks for anions were clear with good resolution and there were no interactions between them. The total time for anion analysis was recorded to be about 28 minutes .Anions like fluoride exhibited drastic change in concentration in surface and groundwater samples taken after discharge of industrial effluents.

Physiological attributes of tomato (Lycopersicon esculentum Mill.) influenced by different sources of nutrients at foothill of eastern Himalayan region
Department of Vegetable and Spice Crops, Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar (West Bengal), INDIA
Abstract : The present investigation was aimed to assess the influence of different organic manures (Farmyard manure and vermicompost), inorganic fertilizers and Azophos biofertilizer on different physiological attributes of tomato. The field experiment was conducted during 2005-06 and 2006-07 at Uttar Banga Krishi Viswavidyalaya (UBKV), Pundibari, Cooch Behar, West Bengal, India by combining 14 treatments in randomized block design with 3 replications. The results revealed that nutrient sources significantly influenced different physiological attributes as the chlorophyll content of leaves and LAI (Leaf area index) kept on increasing and peaked at 60 DAT(Days after transplanting) and 75 DAT respectively and declined thereafter. The dry matter production was highest at 75 DAT. Again application of vermicompost (4 t/ha) with 75% of inorganic fertilizers inoculated with biofertilizer resulted in significant improvement of physiological attributes as well as yield. Vermicompost emerged as better organic nutrient source over farmyard manure. Inoculation with biofertilizer exerted more positive results over uninoculated treatments and benefits of biofertilizer application were more in presence of vermicompost as compared to farmyard manure.

Abstract : Rodent fleas have been considered as the main vector for plague transmission in the rodent population and human plague outbreak usually occur due to the close association of infected rodent fleas with the human being. A total of 910 fleas were retrieved from the 2128 rodents collected from the different areas like Kolar, Palamner, Pune, Surat, Rohru and Chennai. Mainly two types of rodent fleas i.e. Xenopsyalla astia and X. cheopis were found in these areas except the Dodra Kawar area of H.P. state. In Dodra Kawar area Neopsylla kawar species were found and it was very sensitive to the temperature variation. Dodra kawar area usually remains under snow for about nine months and even in the rest of period the maximum temperature does not go more than 20oC. The distribution of X. astia and X. cheopis were found uneven. In surat of Gujarat state X. cheopis was predominantly high, whereas in rest of the area X. astia were found more. In Chennai the main species found was X. astia only. The female percent of rodent flea may be considered as a good indicator for the fast propagation of rodent flea. The breading season for the fleas mostly depends on the climatic condition like temperature below 22oC-25oC, humidity more than 70% even if the outside temperature is more still the shady area the favorable and do help in the survival of fleas. The rapid urbanization and mass use of pesticide in agriculture sector has got significant impact on the rodent flea population and development of resistance to pesticides.

Abstract : This study was done with the aim to identify the specific ergonomic risk factors in the workplace affecting the both male and female workers while doing raw brick making activities and to analyze the pain/discomfort related to it. Twenty male and twenty female workers from the raw brick making unit were randomly selected and a detailed ergonomic risk factors were analyzed with the help of NIOSH Ergonomic Hazard Identification checklist. The questions were based on the primary job responsibility of the workers. Data revealed that nearly 8 percent males and 10 percent females were in ‘usually’ category, 25 percent males and 28 percent females in ‘sometimes’ and approximately 18 percent male and 13 percent females who never performed the task were kept in the category ‘never’. It was found that all the male and female workers usually require exerting force with their hands and used the hand tools to do the task. About 8 percent males and 5 percent females were usually, 15 percent male and only 10 percent female were sometimes and 28 percent males and 35 percent female were never stood continuously for a period of more than 30 minutes. On the whole all the male and female respondents were lifting or lowering the objects between floor and waist height or shoulder height and most of the workers were becoming exposed to the vibration while performing the task and they were carrying the weight more than 50 lb. The study indicates that the majority of the activities are in the high risk category and demands immediate ergonomic intervention in the form of tool, workstation and process design.

Abstract : Assessment of different sources of carbon and nitrogen in terms of dry weight biomass of four selected aquatic hyphomycetes viz; Flagellospora penicilloides Ingold, Pestalotiopsis submersus Sati and Tiwari, Tetrachaetum elegans Ingold and Tetracladium marchalianum De Wildeman was made for their nutritional requirements. Eight carbon sources and ten nitrogen sources were singly added to the basal media in order to provide 4g of carbon and 1g of nitrogen per litre of distilled water. Among carbon compounds glucose and sucrose were found to be most suitable sources of carbon for all the four fungal isolates, whereas fructose proved good for T. marchalianum, P. submersus and F. penicilloides fairly. Cellulose was found a poor source of carbon for the growth of all these isolates. The inorganic sources of nitrogen were found as good nitrogen sources with preference for ammonium ions. Suitability of amino acids was found variable from species to species for nitrogen. T. elegans and T. marchalianum had their maximum growth in asparagines, whereas, P. submersus had their highest growth in proline. Cysteine was observed as a good source of nitrogen for almost all the fungal isolates used. Anova calculated for these observed data showed significant variations in the dry weight production of different fungal species grown in different sources of carbon and nitrogen(P<0.01).

Abstract : The effect of particle geometry and pretreatments on the strength and sorption properties of wood particle cement composite boards was investigated. Wood particles (flakes and sawdust) of Gmelina arborea were mixed with cement and water in the production of composite boards. The wood particles were pretreated with hot water, calcium chloride and a combination of both treatments to enhance bonding with cement. The slurry was poured into rectangular moulds for board formation. After demoulding, the boards formed were tested for modulus of rupture (MOR), modulus of elasticity (MOE), water absorption (WA) and thickness swelling (TS). The results revealed that the mean MOR for flakes boards was 3.23N mm-2 while the mean MOR for sawdust boards was 3.01N mm-2. Hot water and calcium chloride treatment produced the best effect in flake composite boards with MOR and MOE values of 6.90 N/mm2 and 1897.36 N mm-2 while sawdust composite boards had mean MOR and MOE values of 5.69N mm-2 and 1664.31N mm-2 respectively. The WA rate after 24 hours of flakes and sawdust boards treated with hot water and calcium chloride was 3.63% and 4.28% while the TS rate was 0.69% and 1.44% respectively. Particle geometry and pretreatments significantly improved strength and sorption properties of wood particle cement composite boards (p<0.05).

Abstract : The laboratory studies were conducted to resolute the effects of Imidacloprid (insecticide) and Triadimefon (fungicide) singly and in combination on enzymatic activities of soil microorganisms in tomato cultivated soils at different concentrations of 0.2, 0.5 and 0.7 kg per hectare. It was observed that phosphatase, protease and urease activities were elevated noteworthy at 0.5kg per hectare after 10 days of incubation. At lower concentration the activities of these enzymes showed no significant difference from that of control. The combination of the two pesticides led to a pronounced decline of phosphatase and protease enzyme activities at higher concentration. Triadimefon had no effect on urease activity at low concentrations whereas at 0.5 and 0.7 concentrations there was a significant increase when compared to control.

Abstract : A field experiment was conducted to study the impact of biomethanated distillery spentwash and pressmud biocompost in various proportions with inorganic fertilizers on yield attributes, yield, oil and protein content of groundnut at Research and Development Farm of M/s. Bhavani Distilleries and Chemicals Ltd., T. Pudur, Thimiri, Tamil Nadu. Results of the field experiment revealed that yield and yield attributes viz., number of matured pods, 100 kernel weight and shelling percentage of groundnut were improved by the application of biomethanated distillery spentwash and pressmud biocompost compared to recommended NPK as chemical fertilizers. One-time pre-sown application of BDS @ 100 m3ha-1 along with recommended NP in groundnut registered higher pod, grain and haulm yield of 1774, 1272 and 4668 kg ha-1, respectively and the increase was to the tune of 35.83, 43.57 and 46.01 per cent, respectively over control. Similar to yield, BDS application increased the protein and oil content of groundnut kernels significantly. The net returns and benefit cost ratio of sugarcane were also as high as Rs.19,612 ha-1 and 1.90 for the treatment that received pre-sown application of BDS @ 100 m3ha-1 along with recommended NP as compared to control of Rs.19,612 ha-1 and 1.38, respectively. This concludes that the biomethanated distillery spentwash can be conveniently used as source of plant nutrients for groundnut.

Abstract : Pseudomonas aeruginosa has an ability to rapidly develop resistance to most antimicrobial compounds, and to check this ability. The isolates were collected from different pathological human sources and tested for their sensitivity to aminoglycoside antibiotic and to honey, a natural product that is generating renewed interest for its therapeutic application using Kirby Bauer disc diffusion technique. Aminoglycoside antibiotic which is normally active against gram-negative bacteria was used alongside honey. The 29 isolates of P. aeruginosa showed 100% sensitivity to honey tested in their undiluted form. This was not the case with gentamicin (10µg) and amikacin (30 µg), both of which varied in their antipseudomonal activity, like even 1:2 aqueous dilution of honey appreciably inhibited pseudomonal isolates than either of the two aminoglycoside antibiotic. Honey is therefore suggested as an effective natural product in overcoming the widespread antibiotic resistance of P. aeruginosa.

Abstract : Overgrazing by livestock has caused major changes in the productivity and composition of rangeland vegetation in India. The main problem stems from the fact that the carrying capacity of rangelands is low as a result of low vegetation cover, and is decreasing with range degradation. This has an impact on land degradation which affects the rangeland hydrology. Thus the aim of this study was to determine the physio-hydrological responses of soil to different intensities of livestock grazing and land management by comparing the effect of uncontrolled grazed land and fenced off (ungrazed) land. There is a need to understand the hydrology of rangeland so as to propose ways of improving carrying capacity of rangeland. The study site had two different treatments: fenced off to prevent grazing, and uncontrolled grazed treatments. Plant biomass was measured at the end of the season. The results showed that there is a significant difference in infiltration rate and soil moisture among the two treatments. Infiltration rates were substantially greater in summer than in winter. On day 1 the steady infiltration rate in summer was twice the winter rate. The infiltration rate in summer on day 2, which is a better measure of the steady rate, was 2.5 times the winter rate. The differences between seasons were statistically very significant (p < 0.001). The effect of treatments on soil moisture was proportional to the effect of vegetation, as well as the effect of soil type on soil moisture, thus vegetation production depends on soil moisture.

Abstract : A field experiment was conducted with fifty one chilli (Capsicum annuum L.) genotypes to study the growth, yield, quality characters, white fly and yellow mite incidence during Rabi season of 2007-08 and 2008-09. The data on growth, yield performance, quality characters and pest incidence revealed significant variation among the different genotypes. Significantly the highest number of fruits per plant was recorded in genotype CA-29 (168.23) and it was lowest in genotype CA-2 (52.30) and it was statistically at par with genotypes CA-15 (56.09) and CA-43 (56.20). Like number of fruits per plant, the significantly highest fresh yield was recorded in CA-29 (14.58 t/ha). Higher fruit yield was also recorded in genotype CA-47 (13.35 t/ha) and CA-48 (13.18 t/ha). Ascorbic acid content in red ripe fruit varied from 75.89 to 167.21 mg/100 g fresh. The highest capsaicin content in the red ripe fruit was recorded in genotype CA -17 (1.13 %) followed by CA-4 (1.07%) and it was lowest in CA-7 (0.33%). Genotype CA - 45 was almost free from white fly incidence and lower incidence was also recorded in genotype CA-43 (0.40 /plant) followed by CA - 23 (0.50 / plant) and CA - 21 (8.10/ plant) was found most susceptible to white fly incidence. Among the different genotypes, CA - 22, CA - 24, CA - 25, CA - 27 and CA - 30 were free from mite infestation whereas CA - 13 (13.60/leaf) was most susceptible to yellow mite incidence.

Abstract : Laster stream is a major tributary of river Mandakini, which in turn is a major tributary of river Alaknanda. Stream traverses a distance of ~40 km before joining with river Mandakini at Suryaprayag (Tilwara) in Rudraprayag district (Uttarakhand), India. Present study reports existence of twenty one indigenous fish species belonging to eight genera, three families and two orders from the Laster stream. Schizothorax richardsonii (Cyprinidae family) was the dominating species followed by S. plagiostomus, Barilius sp., Tor sp.,Noemacheilus sp., Pseudecheneis sp., Glyptothorax sp. The distribution pattern (diversity and abundance) of these species had negative co-relation with the increase in stream altitude. Habitat conditions in the stream varied considerably from headwater to main stream. Present study also describes the habitat specificity of fish assemblage. Maximum species diversity (18 species) was recorded from pool habitat and was the most preferred habitat. Least species diversity (09 species) was recorded from cascade habitat. Riffle and rapid habitat recorded no difference in species diversity.

Abstract : Though the pesticides have adverse effects but they still are very important in crop protection. Hence, present study on compatibility of fungal bioagent (Trichoderma harzianum) of bacterial leaf blight of rice with chemical pesticides which are commonly used in rice cultivation was carried out with aim to look the possibilities of integrating biological control with chemical control to manage bacterial leaf blight of rice effectively. All the chemical pesticides (fungicides, antibiotic, insecticides and herbicides) exhibited varying adverse effect on mycelial growth of T. harzianum but none of these was antisporulant. Among fungicides and antibiotic, copper oxychloride and streptocycline was compatible with T. harzianum at all concentrations (2000, 1000, 500 and 250 ppm) but mancozeb exhibited compatibility only on lower concentrations (500 and 250 ppm). All insecticides and herbicides were compatible with T. harzianum at all concentrations (2000, 1000, 500 and 250 ppm). Further studies are required in this area of research.

Department of Plant Pathology, G. B. Pant University of Agriculture and Technology, Pantnagar, 263 145, INDIA
Abstract : In the present study, effectiveness of different fungal (Trichoderma harzianum) and bacterial (Pseudomonas fluorescens) bioagent formulations in reducing progress of the bacterial leaf blight disease of rice under field conditions was studied and compared with chemical treatment and untreated check. The results exhibited that after 23 to 30 days after first application, bioagent formulations were more effective then chemical treatment in reducing progress of disease. Bioagent formulations exhibited long lasting effect in reducing progress of disease during Kharif, 2006 and 2007. Application of bioagent formulations resulted in significant reduction (60.5 – 142.8%) in area under disease progress curve (AUDPC) as compared to check during Kharif, 2006 and 2007. Significant increase in grain yield (14.3 - 21.5 %) was observed with the application of bioagent formulations as compared to check during Kharif, 2006 and 2007.

Abstract : Field experiment on the performance of aerobic direct seeded rice (ADSR) under red and laterite zone of West Bengal was conducted at Rice Research Station, Bankura, West Bengal, India during summer season, 2012. The experimental soil was sandy loam with acidic in nature (pH: 5.2). The results exhibited that the grain yield (1 t ha-1) of rice in aerobic situation was low. This might be due to high atmospheric temperature during flowering period, which results in poor grain setting in panicle and most of them became chaffy due to spikelet sterility. Ultimately, it produced low grain yield of rice in aerobic situation during summer season due to high temperature at flowering period, grain formation and grain ripening stages. Thus, aerobic rice system of cultivation needed good management practices.

Abstract : A cross-sectional study was conducted among the residents of three villages of Doda district, J&K. A total of 391 individuals (202 males and 189 females) were examined from 60 households by house to house survey for recording the prevalence and severity of dental fluorosis by using Dean’s Index (1942) along with WHO health assessment form (1997b) and Community fluorosis Index. Of the total studied population 299 (76.47%) have found to be affected with various grades of dental fluorosis with moderate (33.5%) level of fluorosis to be the most frequent category observed. Prevalence of dental fluorosis was more in males (86.61%) than females (63.49%). No significant relation (P>0.05) between prevalence of dental fluorosis to the socioeconomic status was found. Community fluorosis Index was found to be 2.05 which denotes “marked” category of public health significance. High prevalence and high community fluorosis Index suggest that fluorosis is a major public health problem in the area.

Abstract : Knitting industry occupies a pivotal position in the economic dynamism of various countries. The workers in the knitting industry suffer from various types of health risk factors. The risk in the knitting industry is higher and the ability to control it is lower. The majority of the problems are due to poor work environment, manual work condition and long hours of static working posture in the knitting industry. The present study was conducted to study the health and nutritional status of the workers in knitting industry, located in the city Kanpur, India. Body mass index (BMI) technique was used to study the health and nutritional status of the workers. The 300 workers of knitting industry from four different sectors (spinning, knitting, dyeing, and printing) of the industry who worked in a knitting sector were randomly selected from each unit of industry. The anthropometric measurements viz., height in cm, weight in kg of each respondent was recorded. The results revealed that the selected sample was suffering from occupational stress and health problems. Out of total 300 workers, majority of the respondents (22.00%) were in CED Grade III (Severe) category followed by 16.00% in CED grade IV (Moderate), 14.00% in low weight normal, 12.00% in CED Grade I (Mild), 11.00% in obese grade I and 10.00% in obese grade II. Only 17.00% respondents were observed under normal nutritional status. Thus, the respondents were suffering from occupational stress and health problems.

Department of Plant Pathology, G. B. Pant University of Agriculture and Technology, Pantnagar - 263 145, INDIA
Abstract : In the present investigation, fungal and bacterial bioagents which were effective against pathogen of bacterial leaf blight disease of rice (Xanthomonas oryzae pv. oryzae) was tested for their effect on germination of rice seeds and growth of nursery seedlings under laboratory and glasshouse conditions. Two isolates of fluorescent pseudomonas isolated from rice phylloplane (Pf 83 and FLP 88), Trichoderma species were isolated from soil of rice field (isolate 40) and Trichoderma harzianum isolated from rice phylloplane. Two commercial formulations (PBA-1 and PBA-2) were tested in the present investigation and compared with chemical treatment (0.76 g Emison + 0.18 g Streptocycline/kg seeds) and untreated check. Under laboratory conditions, chemical treatment was found most effective in increasing seed germination (43.90%) followed by Pf 83 and PBA-1 (34.15 %). Bioagent formulations were significantly effective in increase in root and shoot length as compared to check and chemical treatment. Under glasshouse conditions, maximum increase (29.42%) in seedlings emergence was exhibited by chemical treatment. Maximum increase in root length (100.15%) and shoot length (50.06%) was recorded with FLP 88 and T. harzianum, respectively. Bioagent formulations also increased fresh and dry root weight over check and chemical treatment. All bioagents formulations were effective over chemical treatment and check in increasing fresh shoot weight. Results of the present study revealed that in the absence of pathogen of bacterial leaf blight of rice, fungal and bacterial bioagents significantly enhanced germination of rice seeds and growth of nursery seedlings.

Abstract : A serious collar and rhizome rot disease of banana was observed in the north region of Maharashtra state in post rainy season. The disease was caused by the bacterial strains of Erwinia chrysanthemi pv. paradisiaca identified and characterized by morphological, physiological, biochemical and pathogenicity tests. The infection occurred on new banana plantation of one month old in poorly drained soil. In post rainy season, banana plantations of 8 to 10 weeks were found severely infected. E. chrysanthemi pv.paradisiaca produced soft rot symptom on healthy banana rhizomes within three weeks. Two strains were isolated from the collar and rhizome rotted diseased samples which were similar in morphological, physiological and biochemical characteristics, however they differed in the virulence aggressiveness to cause the disease in banana. Strain II caused soft rot symptoms within 19 days, however strain I produced it within 23 days of inoculation with suspension of 3×108 CFU ml-1. The result of this study revealed that strain II was more aggressive as compared to strain I of E. chrysanthemi pv. paradisiaca.

Abstract : The growing of trees could be hindered by seed dormancy problems or unavailability of sufficient quantities of seeds, hence vegetative propagation using simple propagules like stem cuttings is a valued option especially for resource poor farmers. The rooting potential of mature stem cuttings of Gambeya albida, Irvingia gabonensis, Annona muricata, Garcinia kola and Triplochiton scleroxylon was investigated in a humid tent propagator without enhancement by artificial hormones. Propagation indicative parameters were estimated using percentages. G. kola had the highest root-ability indices with cutting survival rate of 85%, callus formation (75%), leaf loss (35%), days to axial bud sprout (55 days), days to leaf loss (23 days) and number of new leaves produced (9) at termination of study. T.scleroxylon had no survivals; an axial bud sprouted at 51 days but withered off by the third day. Other species were between these two extremes. Root-ability potential categorization for the species on the basis of this investigation was: easy to root for: G.kola and A.muricata, moderately easy to root for I.gabonensis and G.albida, unable to root for T.scleroxylon. The use of artificial hormone, juvenile stem cutting and somatic embryogenesis trials has been suggested especially for the moderately easy and unable to root categories.

Abstract : The present study aimed to evaluate the antibacterial potency of grinded crude material (root of Glycyrrhiza glabra) against some gram-positive and gram-negative bacterial strains. Two solvents (methanol and acetone) were used to extract the phytochemicals from the test material. Four different concentrations (100%, 75%, 50% and 25%) of methanolic and acetonic extract were used to investigate the inhibiting properties against Salmonella typhi, Escherichia.coli, Vibrio cholerae, Staphylococcus aureus, Bacillus cereus and Bacillus subtilis strains. Among methanol and acetone extracts, later exhibited low antibacterial activity. The 100% (w/v) concentration of both extracts showed maximum inhibition against B. subtilis followed by E. coli, S. aureus, B. cereus, S. typhi and V. Cholerae. Maximum activity in acetonic extract was obtained against B. cereus followed by S. typhi, E. coli, V. cholerae and S.aureus and minimum in B. subtilis. A reverse pattern of inhibition activity was found in both extracts (methanolic and acetonic) against B. subtilis. Maximum activity was found in methanolic extract against B. subtilis (18.6 mm) but it was only 14.3 mm against this strain in acetonic extract. The antibacterial activity of the crude samples corresponded to that of concentration. Hence there was positive correlation of antibacterial activity with the test material.

Abstract : The physico-chemical and phytoplankton characteristics of the Tons River were analyzed during August 2011-July 2012. The samples were collected from Garhi Cant (Site 1) and Tapkeshwar temple (Site 2) at Dehradun. The results showed that temperature, velocity, DO, nitrate and phosphate affected the phytoplanktonic diversity of river Tons. Thirty five genera of phytoplankton belonging to three families of Chlorophyceae, Bacillariophyceae and Myxophyceae were also identified in the river water. The family Bacillariophyceae was dominating the river with much abundance throughout the study period. Bacillariophyceae was recorded with the maximum of 222.25±90.84 Unit/L at sampling site 1 and 239.08±125.41 Unit/L at sampling site 2. The greater number of individuals was in family Bacillariophyceae (239.08±125.41 Unit/L) followed by Chlorophyceae (183.75±112.50 Unit/L) and Myxophyceae (40.91±36.16 Unit/L) during the study period. Both the number of genera and number of individuals belonging to each genera was maximum in case of family Bacillariophyceae followed by Chlorophyceae and Myxophyceae. The present study revealed that the water quality of river Tons was fairly good for the growth and survival of phytoplankton, and as a result it sustains the higher phytoplankton diversity of Tons river.

Abstract : The present investigation observed the effect of current density (CD), operating time (OT), inter electrode distance (IED), electrode area (EA), initial pH and settling time (ST) using Fe-Fe electrode combination on the removal of chemical oxygen demand (COD) and biochemical oxygen demand (BOD) from biologically treated municipal wastewater (BTMW) of Sewage Treatment Plant (STP). The maximum removal of COD (92.35%) from BTMW was found with the optimum operating conditions of CD (2.82 A/m2), OT (40 mins.), IED (0.5 cm), EA (160 cm2), initial pH (7.5) and ST (60 min.), while the maximum removal of BOD (84.88%) was found with the ST (30 min.) at the same operating conditions. There was no need of pH adjustment of the BTMW during ET as the optimal removal efficiency was close to the pH of 7.5. Under optimal operating conditions, the operating cost was found to be 54.29 Rs./m3 / 1.08 US$/m3 in terms of the electrode consumption (78.48 x 10-5 kg Al/m3 ) and energy consumption (108.48 Kwh/m3).

Abstract : The increasing cost of animal protein has necessitated the need to investigate the use of cheaper and nutritive alternatives in various food formulations. The study was carried out to determine the appropriate level of soy flour inclusion in meatball production. The soy meat balls were formulated to contain 0%, 10%, 15%, 20% and 25% of full-fat soy flour which was combined with beef and some condiments. Treatments were analyzed in triplicates in a randomized complete block design. A 7-point hedonic scale was used to evaluate the sensory characteristics (colour, taste, texture and overall acceptance) of the products using a semi-trained taste panel. Nutrient proximate composition values and production cost were also determined. Results showed that on the average, soy flour inclusion in meatballs increased cooking yield by reducing weight loss from 27.33% to 12.96%. Meatballs with soy flour inclusions at 10% and 15% were most acceptable (very much liked). The 20% and 25% level of soy flour inclusion were moderately acceptable, thereby indicating acceptability up to 25% level of soy flour inclusion. Soy inclusion reduced production cost by N37.50 on the average at N5.00 per ball when compared with all meat products as well as, increasing the number of balls per mix from 64 balls (control) to an average number of 89.5 balls (soy meatball). It is recommended that further studies of the soy flour inclusion in meatballs production be carried out to ensure the availability of cheaper, nutritious and acceptable convenience food in the Nigerian market.

Abstract : The solvent evaporation technique was used in this study to evaluate probiotics microencapsulation in AQOAT/ dichloromethane matrix and cell viability was also measured to assess its potentials in industrial food formulation processes. Cumulative release experiments using water blue dye as a model molecule was also used to evaluate the prebiotic applications. Well-defined spherical AQOAT microcapsules [50.0 ìm ± (24.14)] were formed from 5% AQOAT solution. Cells of Bifidobacterium breve and Lactobacillus plantarum were successfully encapsulated with this technique. However, a 7 log and a 5 log reduction were recorded for B. breve and L. plantarum respectively after 60 min in buffer (P<0.05). Results of this study showed that 1% AQOAT solution lowered viability by 1 log and cell exposure to 10 ml dichloromethane resulted in a 3 log reduction, thus confirming bactericidal properties of both polymer and organic solvent. DCM was however shown to have more bactericidal effects on the cells (P<0.001). Cumulative release trials using 0.2% water blue dye solution showed a 40% loss and encapsulation efficiency (EE) of 73.8% (±14.76). It was recommended that viability counts using this technique be further evaluated using other organic solvents (such as ethyl acetate and chloroform) or other synthetic polymers so as to increase its applicability in the food industry.

Abstract : An ambient air quality study was undertaken in Bareilly city, U.P., India during the year 2010 and 2011. The seasonal air quality data was obtained from ten monitoring sites across the city considering sampling site of Cantt as control site. The maximum (713.06±55.64 µg/m3) suspended particulate matter (SPM), sulphur dioxide (SO2) (80.08±4.77 µg/m3) and nitrogen oxides (NOx) (64.98±3.53 µg/m3) level was found at Choupla during the winter 2011. Among the annual mean values of air pollutants were analyzed, SPM level was found to be above the National Ambient Air Quality Standards (NAAQS) (200 µg/m3) at all the polluted sites. SO2 and NOx levels were below the threshold limits (80 µg/m3) as per NAAQS. The ambient air quality was correlated with the traffic density in the city. The pollution level was observed to be positively correlated with traffic density which is the major source of air pollution in the city. The ambient air quality at different monitoring sites was categorized into different pollution level on the basis of Oak ridge air quality index (ORAQI). Light to moderate air pollution conditions were present at different sites. Sampling site of Choupla (SVII) observe maximum ORAQI of 64.48 and 70.81 and falls under category of moderate pollution.

Abstract : The present study observed the accumulation of heavy metals in Brassica juncea irrigated with paper mill effluent (PME) and control Bore well water (BWW). The soil was treated to five rates of effluents viz. 10, 25, 50, 75 and 100 ml/Kg soil. It was revealed 100% PME irrigation of soil increased Pb (+46.44%), Cr (+83.21%), Ni (+38.43%) and Cd (+78.92%). The enrichment factor (Ef) for Cr and Cd showed moderate enrichment with 10% to 75% PME irrigated soil, except Cr (5.96) which showed significant enrichment with 100% PME irrigated soil. Ef value for Pb and Ni showed deficiency to mineral enrichment with different concentrations of PME irrigated soil. The maximum accumulation of Pb (42.66±2.05 mg/kg), Cr (39.80±5.95 mg/kg), Ni (88.64±11.29 mg/kg) and Cd (5.85±0.29 mg/kg) were recorded in leaves of B. juncea, while that of Pb (43.85±3.46 mg/kg), Cr (48.59±3.81 mg/kg), Cd (6.74±1.22 mg/kg) with 100% and Ni (74.93±2.54 mg/kg) were recorded with 75% PME after 60 days in roots of the B. juncea. Ef value was found maximum for Cr (5.08) in leaves and for Pb (6.64) in roots, while the Translocation factor (Tf) was found maximum for Pb (2.45) in root of the crop irrigated with PME. The use of PME with proper dilution and with the metallic concentrations in permissible limit can be used as biofertigant for irrigation of B. juncea.

Abstract : The present study presents an overview on floral diversity and identifies Non-timber Forest Products (NTFP) that can be used as Natural Dye sources in textile sector. This was a descriptive study; Historical, as well as current data was collected through surveys and interviews. Individual and focus group interviews with tribal members were conducted to gather information regarding details of forest proximity. This collective study indicates that the Aravalli hill ranges constitute the most dominant hilly area of Rajasthan. Most of the forests are over the hilly areas i.e. in Udaipur, Rajasamand, Kota, Baran Sawai Madhopur, Chittorgarh, Sirohi, Bundi, Alwar, Jhalawar and Banswara districts, which make up for about 50 per cent of the forests of the state. Khakara, semal, rohida, gadha palash, mokha, marod phalli, davai, van gulab etc. are identified as red chroma, amaltash, awla, gundhi, babool etc.are identified as yellow and related chroma. Forests are major components of the earth’s natural resources and they are increasingly critical to the welfare of the economy, environment, and population. Gum products, starch products, antimicrobial resources, paper industry products may be collected from hilly forest areas and can be easily adopted at cottage level for gainful employment of tribal women.

Abstract : Evapotranspiration (ET) is an essential component of the water balance. Any attempt to improve water use efficiency must be based on reliable estimates of ET, which includes water evaporation from land and water surfaces and transpiration by vegetation. ET varies regionally and seasonally according to weather and wind conditions. Remote sensing based agro-meteorological models are presently most suited for estimating crop water use at both field and regional scales. Numerous ET algorithms have been developed to make use of remote sensing data acquired by sensors on airborne and satellite platforms. The use of remote sensing to estimate ET is presently being developed along two approaches: (a) land surface energy balance (EB) method and (b) Reflectance based crop coefficient and reference ET approach. The reported estimation accuracy varied from 67 to 97% for daily ET and above 94% for seasonal ET indicating that they have the potential to estimate regional ET accurately. Automated contours are not confined to specific pre-determined geographic areas (as in MLRA), require less time and cost. The spatial and temporal remote sensing data from the existing set of earth observing satellite platforms are not sufficient enough to be used in the estimation of spatially distributed ET for on-farm irrigation management purposes, especially at a field scale level (~10 to 200 ha). However, research opportunities exist to improve the spatial and temporal resolution of ET by developing algorithms to increase the spatial resolution of reflectance and surface temperature data derived from K1VHRR/Landsat/ASTER/MODIS images using same/other-sensor high resolution multi-spectral images.

Abstract : An analysis has been made as regards emission characteristics of ocean energy systems from life cycle assessment and scope of energy availability from energy accounting studies. Assessment tools developed and standardized were the indices like scope of Green house gases (GHG) emission per kWh power generation, percentage of CO2 saved compared to coal fired power station and the energy payback period. Emission characteristics of ocean energy systems were also compared with that from solar power, bio-fuels and wind energy systems. Four case studies were made comprising of wave energy converters, Ocean Thermal Energy Conversion (OTEC) system and tidal energy. It could be observed that CO2 emission percentage saved from ocean energy schemes were more than 95 per cent; and energy payback period varied between one year and a little higher than two years, depending on the type of the device.
