This study aims to analyze the reject produced by the desalinators implanted in the semi-arid Pernambuco in contact with the seeds of Moringa oleifera Lam. For this, Moringa seeds were collected and prepared with the following treatments: reject (control), reject with whole seed with and without husks, reject with crushed seed with and without husks, seed residue with and without husks, in five replicas. Each replica was constituted with doses equivalent to 2.0 g of Moringa seeds for 200 mL of reject, with contact time corresponding to 30, 60, 120 and 180 minutes, in a completely randomized design, under laboratory conditions, total of 140 experimental units. The physical-chemical and statistical analyses were performed through analysis of variance (ANOVA), and the F test, at confidence interval of 95%. It has been found through laboratory tests that seeds with crushed or ground Moringa husks are equally effective at adsorbing sodium from 1,868,0 mg/L to 24,6 mg/L (98,7 %), calcium from 1,005.0 mg/L to 894.6 mg/L (11%), magnesium from 741.0 mg/L to 728.3 mg/L (1.7%) and chloride from 6,997.5 mg/L to 6,782.4 mg/L (1.8%). Therefore, Moringa seed can be considered promising in the adsorption of chemical elements of saline water desalinizers.

Manipulations of crucial information during interaction in organization is deception with the organization too as it impacts the overall productivity and progress of the organization. The current study was an attempt to study the perceived prevalence of organizational deception using IMT. A questionnaire was constructed in two parts for direct and indirect analysis to elicit responses regarding prevalence of deception. The study concluded that faculty members use deception for different motives which may carry serious consequences in the organizations. It is further inferred that ‘self benefit’ is the major motive of deception followed by ‘others’ benefit’ while ‘harming others’ came out to be least prevalent motive of violation of messages. The study is one of the initial steps towards using IMT theory for studying prevalence of deception. Looking into the vast scope of research in this area, the researchers can further probe deception in different interpersonal situations.

The experiment was conducted at the Agriculture Research Station, College of Agriculture, Anand Agricultural University, Jabugam during three consecutive seasons of the years 2015-16 and 2016-17. This was to evaluate banana Pseudostem and maize fodder waste with and without cow dung and Anubhav biodegradable bacterial consortium (ABBC) for it bi-product in terms of vermi-composting, time required for degradation and the nutritive quality of vermicompost. The experiment consisted of eight treatments and conducted in RBD with three replications. Results shows that, the treatment Banana pseudostem + 5% Cow dung + Anubhav biodegradable bacterial consortium and the treatment Maize fodder waste + 5% Cow dung + Anubhav biodegradable bacterial consortium were significantly higher  for N, P, K content during all the three seasons and in pooled analysis with less number of days to harvest and high recovery. While, microbial count were recorded maximum in banana Pseudostem based vermicompost than maize fodder waste. Overall, vermicompost produced from the banana Pseudostem and maize fodder waste by using ABBC @ 1 lit/t and 5 % cow dung provided the major nutrients in more balanced proportion. The main perspectives of this study is to decrease the environmental pollution by making vermicompost from banana pseudostem waste or maize fodder (waste) instead of dumping on road side or burning or left in the field and also reduce the use of chemicals by using vermicompost.

The Electrical Resistivity Tomography (ERT) data was acquired within the area suspected to have high potential for bitumen occurrence using the Wenner-Schlumberger configuration in Agbabu, southwestern Nigeria. PASI 16GL-N Earth resistivity meter instrument was used to acquire data along five (5) traverses with 5m electrode spacing and traverses length of 150m. The apparent resistivity values obtained was processed using RES2DINV software which helped to automatically obtain the 2D inversion model of the subsurface. This study has shown the occurrence of bitumen between the depth of 13.4m and 9.93m for Traverses 1, 2, 3 and Traverses 4, 5 respectively in a 2-Dimensional electrical resistivity images for boreholes with a depth of about 18m. The results indicate that the bitumen is characterized by good lateral continuity and is sufficiently thick for commercial exploitation.

Aims: Experiments were conducted to evaluate the specificity and rapidity of the application of conventional, immunoassay and direct Polymerase Chain Reaction (dPCR) techniques in the detection of Bacillus cereus and its toxins in contaminated rice.

Place and Duration of Study: Department of Life Sciences, Glasgow Caledonian University, UK, between May 2015 and December 2015.

Methodology: Conventional testing for the presence of B. cereus and associated toxins was achieved using Polymixin Egg-yolk Mannitol Agar (PEMBA) culture plates while immunoassays were conducted using a commercially available Reverse Passive Latex Agglutination (TD0950 BCET-RPLA, Oxoid, UK) kit. Direct PCR was used to detect the HBL-E gene in the food samples and the PCR amplicons were visualised after separation by gel electrophoresis.

Results: Total Mean B. cereus count was recorded as 5.3 ×107 cfu / g of the rice sample from the PEMBA plate culture. The PEMBA method was the least in terms of rapidity of assay completion. Further assays such as the RPLA and dPCR assays were tested for potential in overcoming this limitation. Results from the immunological study showed that sample agglutination with sensitised latex beads was only positive up to the 10-2 dilution which is an indication of the presence of the Haemolysin BL enterotoxin (HBL-E). The PCR assay had the lowest limit of detection (5.3 ×106 cfu / g) thereby suggesting that the method has very low sensitivity for the bacteria. However, the PEMBA method was more sensitive but had highest detection limit (100 cfu / g) than the RPLA assay (5.3 ×105 cfu / g).

Conclusion: Although the dPCR had the advantage of producing results within a short time, it was less sensitive to B. cereus than RPLA and PEMBA assays. A development of improved highly sensitive assay for the toxin has the potential to enhance food safety.

Food security with increased and sustained production of the major cereal crops in India is the need of the hour. The role of farmers as informal extension agents has been depicted in many recent studies emphasising the need for studies on network linkages between the farmer communities and the stakeholders in dissemination and adoption of improved technologies. The present study has been conducted to understand the role of social networks in the diffusion of CAU-R1 variety among the farmers of Manipur. The research design employed was exploratory and the sampling procedure was mixed sampling with purposive sampling for the selection of the state, district and key farmers. Snowball sampling was used to identify other farmers in the network. The sample size was 64 farmers from eight villages in Imphal East district. The socio-economic profile of the farmers showed that majority belonged to medium age between 36 years to 50 years, medium level of innovativeness, social participation, cosmopoliteness and risk bearing ability. The Social Network Analysis measures employed for the study were the centrality measures that include the degree, closeness and betweenness centrality to identify the most central, influential and powerful actors in the network. The average in-degree and out-degree was found to be equal for all the villages with a maximum degree centrality of 16. The betweenness centralization index of the networks was very low (24.55%) indicating very slow rate of spread of information and information sharing restricted only between few actors in the network. Social participation and trainings were positively correlated while the farming experience and time taken for adoption were negatively correlated with the network measures. The outcomes revealed that there is need for a more concerted effort by the farmers and stakeholders to sensitize farmers about the variety through exposure visits, trainings, incentives and timely input supply.

The objective of this work was to analyze the minerals extracted from the soil and absorbed by Atriplex nummularia Lind. submitted to Claroideoglomus etunicatum and to the desalinator reject. The experiment was conducted in a greenhouse at the Agronomic Institute of Pernambuco - IPA, Recife, Pernambuco, Brazil. The experimental design was of randomized blocks with the treatments constituted in a factorial scheme, in five levels of salinity: AC: 2.87 mS / cm; T1: 11.54 mS / cm; T2: 12.04 mS / cm; T3: 13,13 and T4: 14,16 mS / cm, associated with the presence and absence of AMF, presence and absence of nutrient solution and autoclaved and non-autoclaved soil. 8.0 ml of Hoagland & Arnon complete nutrient solution was added every fortnight. After five months, the contents of the elements absorbed by the plant and present in the soil were evaluated. It was observed that in non-autoclaved soil Atriplex absorbed higher nutrient content. Furthermore, the best treatment was the T4 of EC of 14.16 mS/cm + AMF + Hoagland & Arnon solution. Therefore, the high sodium content absorbed (22%) by Atriplex evidences the potential of its use in phytoextraction programs in soils affected by salts.
