This study aimed at finding out the efficacy of electrostatic sprayer on pest control in comparison with mist blower and air compression sprayer. Six pests were selected based on specific characteristics viz. integumental, movement and ecological niche. Energy use efficiency in production and application of pesticides used by different sprayers for the control of selected pests were quantified based on application efficiency, pre and post pest count and reoccurrence of pest infestation after spray. The greenhouse gas emission for the total energy usage for the corresponding quantity of pesticide were computed for all the selected sprayers. The energy use efficiency of electrostatic sprayer was found to be 1.5 times more than that of mist blower and 2 times more than that of air compression sprayers. The chemical usage by electrostatic sprayer was reduced by 65%, and that of knapsack mist blower was 35% with air compression sprayers. The corresponding greenhouse gas emission was only 20% for electrostatic sprayer and 65% for powered mist blower than that of air compression sprayers. The post pest count was almost nil in all the categories of pest while applying with electrostatic sprayer and the reoccurrence of the pest to the threshold level was minimum. This contributes a significant reduction in emission of CO2 when considered globally, and ultimately contribute to mitigation of global warming.

This study allowed appreciating hygrothermal behavior, thermal comfort and the visual comfort of an existing Nubian vaulted building in the city of Ouagadougou. To achieve that purpose, we measured parameters such as the temperature and relative humidity of the indoor and outdoor environments as well as illumination by daylight inside the studied building. The measurement campaign consisted of two (02) series of three (03) days in January 2018: one series with insulation of the louvered openings by polystyrene and the other series without the insulation. We carried out the measurements of relative humidity and illumination at 7, 10, 12, 15, 17, 20 and 22 o'clock and adopted a one-hour measurement time step for temperatures. The analysis of these parameters showed that the level of natural lighting in the building was insufficient. In addition, for the indoor ambiance, we have obtained indoor thermal amplitude less than 1.5°C, a decrement factor of less than 6%, a time lag of 6 to 8 hours. As for operative temperatures, they are within the thermal comfort zone of the Givonni diagram. As for the couple (Temperature, Relative Humidity), the thermal comfort zone proposed by Givonni is reached when the louver openings are insulated.

This work probes the kinetics and thermodynamics of adsorption of methylene blue (MB) from aqueous phase on a templated carbon (TC) synthesized from polyfurfuryl alcohol using kaolinite template at 773 K; and activated carbon produced by the pyrolysis of H3PO4-impregnated Moringa oleifera seed hull (MOSH) at 723 K. Factors such as initial concentration of MB (1-3 mg/50 mL), reaction time (0-60 min.) and temperature (302-328 K) for the process were investigated using isotherms, sorption kinetics and thermodynamics. From the results obtained, adsorption of MB on TC fits both Langmuir and Freundlich isotherms well. The Langmuir isotherm describes adsorption of MB on the activated carbon from MOSH (MOSHC) better than the Freundlich isotherm. The adsorption capacities of the active carbons observed for MB were 29.3 mg/g for TC and 29.8 mg/g for MOSHC. The thermodynamic values evaluated:  (14.15 kJ/mol. and 11.48 kJ/mol.),  (87.93 kJ/mol. K and 49.55 kJ/mol. K) and  (7.10 kJ/mol. and 14.26 kJ/mol.) for TC and MOSHC respectively, indicate endothermic and physical nature of adsorption, and enhanced randomness at the adsorbate-adsorbent interface. The sticking probability ( ) values (3.25 x 10–3 and 1.36 x 10–4 for TC and MOSHC respectively) show that the probability of MB molecules sticking on the surfaces of these active carbons is very high, with that for MOSHC being higher. Negative  values (– 12.28 to – 14.68 kJ/mol.K and – 3.56 to – 4.92 kJ/mol.K) for TC and MOSHC respectively, at 302–328 K confirms a spontaneous adsorption process dominated by physisorption. Adsorption of MB on TC supports multilayer formation and was dominated by pseudo-second order kinetics while its adsorption on MOSHC was dominated by pseudo-first order kinetics with a single MB molecule occupying more than one active site. MOSHC, the low-cost adsorbent prepared, is thus very assuring for the removal of organic pollutants like MB from aqueous systems.

DOI: 10.9734/cjast/2020/v39i2930956

This paper investigates the trends in area, production and yield of major pulses in India by using component growth rate, Instability index and decomposition analysis during last twenty years. Further the study period has been divided into three periods based on the implantation of NFSM: Pre NFSM period I (1995 to 2006), Post NFSM period II (2007 to 2016) and Overall period (1995 to 2017). The result of CGR in total pulses revealed that the area (1.87%), production (3.58%) and yield (1.89%) registered highly positive significance with increased growth in period II. The yield growth rate was higher than area growth rate implying that the area allocation under pulses is increasing poorly even after NFSM scheme, while improvement in yield is there. The instability of total pulses production and productivity has first decreased and then increased in the overall period its shows increased growth. Among the major crops, the area effect was high in lentil production and by yield effect was high in gram production and the interaction effect was high in moong production during the overall study period. In case of total pulses, area and yield effects were positively higher and they were responsible for total pulses production.

The present study was conducted to assess the empowerment level of women in the fisheries sector in the Ganjam district of Odisha. In the inland sector, the highest numbers of women are of the fishermen population in Ganjam district i.e. 29476 out of a total 263514 number of female fisheries population of the state (Directorate of Fisheries, Government of Odisha, 2015). A very good concentration of women is involving in fisheries activities in this district. But when sector-specific cases are concerned, there are very few studies found where different dimensions of women empowerment through fisheries are discussed. The results revealed that the majority of the respondents (66.60%) in the Inland sector are grouped under a medium level of empowerment followed by low and high-level empowerment (16.70%). These results indicated that there is a significant move towards the empowerment of women in the case of inland fisheries. However, in the Marine sector equal percentage of respondents belonged to both medium and high levels of women empowerment i.e. each 30 (50.00%) and low level of empowerment was nil which indicates the level of empowerment in the marine fisheries activities compared to inland fisheries. With this background, the overall empowerment score was categorized into the low, medium, and high level of empowerment where a majority of the respondents (71.6%) were under the medium level of empowerment followed by the equal percentage of the low and high level of empowerment (14.2%). The composite score of empowerment of women is also encouraging. However, efforts are needed to bring women empowerment from medium level to a higher level. There is also a need to uplift a section of women who are still in the lower category of empowerment.

The study was aimed to investigate the production performance of wheat in western Maharashtra. The data of 20 years regarding area, production and productivity of wheat was made available through the secondary source for all the districts of the western Maharashtra region. The study period of 1996-97 to 2015-16 was split into two sub periods i.e. period-I (1996-97 to 2005-2006), period-II (2006-07 to 2015-16) and overall period. The growth rates were calculated using the exponential function. The instability in area, production, and productivity was measured with a coefficient of variation (CV) and Cuddy Della Valle’s Instability index. The relative contribution of area and yield to change in output was estimated by Minhas decomposition model. The district-wise analysis was carried out which resulted that, during the period-I and period-II, almost all districts in the western Maharashtra region registered negative growth including the region as a whole. The area and productivity showed stability in wheat crop in almost all the districts of western Maharashtra region. In the western Maharashtra region, among all the parametric models fitted to the area, production and productivity of wheat crop, the maximum R2 was observed in the case of cubic model in all the districts of Western Maharashtra region with the region as a whole. The region as a whole recorded 59 per cent which marked as the highest R2 in productivity as compared to area and production. The decomposition analysis for western Maharashtra region depicted the largest area effect on wheat production. It was also observed that for both periods the area effect was more pronounced than the yield effect and interaction effect. Hence, there is need for policy maker to formulate development-oriented policies and the researchers to design an investigative research activity for promoting a sustainable wheat production system in the region for expansion of area under wheat cultivation.

Breeding for drought tolerance revolves around selection of genotypes with desirable root characters. Root pattern studies in rice have shown significant relationship with drought tolerance. In order to understand the effects of deep rooting pattern and root growth angle in relation to water stress was assessed following basket method. The Backcross inbred lines (BILs) of ADT (R) 45*1/Apo and ADT (R) 45*1/Wayrarem with drought QTLs viz., qDTY1.1, qDTY3.1, qDTY4.1 and qDTY12.1 were evaluated for various root traits.  Out of 20 BILs and three parental lines studied four BILs showed high values for root growth at deep angle 65-90 °and yield under drought stress. Based on association studies among the root traits positive and significant correlation was observed between yield and root traits viz., root dry weight, root growth at deep angle 65-90° (RA4), ratio of deep rooting and root length. Clustering of BILs and parents have grouped deep rooting BILs and drought tolerant donors into one cluster and drought susceptible ADT (R) 45 into a separate cluster II which clearly indicates, the importance of deep rooting and yield under drought stress. Strong association of root traits and drought tolerance clearly shows the importance in utilization of these traits as selection criteria for drought tolerance in rice.

Election voting has emerged as a significant alternative to conventional voting methods with testimonials of its implementation showing various degrees of success in some countries of the western world. Lately, many developing countries are also looking at its prospects as a replacement or supplement for traditional paper balloting which is, the principal voting method in most of these countries. However, the voting populace’ acceptance of this technology is a major factor that needs to be considered before its actual introduction owning to factors that includes, digital divides, low literacy level, norms and beliefs, high poverty level and so on. From another viewpoint, due to the peculiarity of contextual ICT infrastructural challenges of developing countries, there is a need to investigate the factors that will influence adoption decision and eventual usage when planning to introduce electronic voting so that the evolving system will not end up being impractical for the target users. In this study, an empirical investigation of the factors influencing the adoption decision of electronic voting was carried out.  More specifically, this study aimed at examining the possibilities and intents towards mobile voting (which is a type of electronic voting), among a selected sample population of electorates in Nigeria. In the study, an extended Technology Acceptance Model (TAM) that integrates Subjective norm, Perceived compatibility, Perceived privacy, Perceived security, Perceived price value and Perceived trust into the original TAM constructs was proposed. A total of 1364 sample data were collected from a selected population of electorates who had at one time or the other participated in at least an electioneering process in Nigeria.  The data was then analyzed statistically using Partial Least Square           Structural Equation Modeling (PLS-SEM). The results obtained show that all variables have significant effect on the electorates’ behavioural intention to use mobile voting except for perceived privacy.
