Abstract

Growing need of agricultural production has been greatly felt with the growth of population, not only for the sake of food security but also for providing employment. Crop diversification within the sector has also been noticed to a great extent. Of which, the growth of production of maize has registered at the highest with CAGR at 8.5 per cent in the last three decades. Using one way Least Squares Dummy Variable (LSDV) for twenty-seven districts over twelve years, present study explored that the introduction of new hybrid seed (HYV) is one of the most important factors for significant growth of maize crop in the state. Further, though the crop is suitable in the drier region, the role of timely rainfall is also found to have significant on the yield level.

Abstract

The symptoms of depression might be alleviated by such non-pharmacological interventions as sleep deprivation, bright light exposure, and physical exercise. Some strategies of non-drug treatment for seasonal and non-seasonal depression seem to be very effective, but the involvement of specific biological mechanisms in the observed beneficial response still remains to be clarified. A present literature review was combined with a brief summary of the results of a set of author’s investigations that provided a possibility to compare the antidepressant effects of several one-week treatments in 268 female subjects with either winter depression or non-seasonal depression or without depression (n=118, 64 and 86, respectively). It was demonstrated that a total night sleep deprivation failed to improve mood in non-depressed subjects, whereas in seasonally and non-seasonally depressed subjects the significant improvements of similar magnitudes were observed. Furthermore, any type of one-week treatment (i.e., 6 or 7 days of bright light, physical exercise, melatonin or placebo intake, and vocation in a south region) administered either alone or in combination with one night of sleep deprivation produced a notable reduction of depression scores in both depressed and non-depressed subjects. Such treatments prevented relapse after sleep deprivation. Mood further improved after visual treatments, such as bright light and physical exercise, rather than after blind intake of ether melatonin or placebo. The studies of natural antidepressants highlighted the possibility that they often work as powerful placebos, and that, compared to the biology of depressives; their psychology is the most important mediator of clinical response. Further research might be aimed on testing the predictions based on evolutionary explanation of depression and antidepressant responses to natural treatments.

Abstract

In general aerospace, civil and mechanical (ACM) structures are often subjected to some or the other forms of loading during their service life. It has been reported that about 75% of aerospace structures fail due to fatigue cyclic loading. The civil-structural components are subjected to some form of axial and transverse loading which continuously deteriorates the health of the structure. Mechanical components are also subjected to stresses due to contact pressures between several components. Thus for ACM structures, effective monitoring through-out the entire life is required as these often involve public life and huge investments. Owing to such necessity, researchers around the world are continuously working on the development of smart sensor based effective monitoring techniques. Piezo electric (PZT) transducer based electromechanical impedance (EMI) is one such technique which was developed for structural health monitoring (SHM). In this technique, PZT transducers are usually attached to the structure to be monitored and are then subjected to unit sinusoidal electric voltage to generate the electromechanical (EM) admittance signatures when interrogated to the desired frequency range of excitations. These signatures consist of real (conductance) and imaginary (susceptance) parts which serve as indicator to predict the structural health. Any deviations in these signatures during the monitoring period indicate disturbance in the structure. However, the EMI technique was not widely explored for structural load monitoring (such as fatigue cyclic load, monotonous load, axial and transverse load) compared to damage detection. In this paper, systematic experiments were presented on the specimens for axial load variations, transverse load variations, monotonous and fatigue load variation with discussions on boundary effect and buckling effects. For axial, fatigue, monotonic load, the conductance was found to be effective where as for transverse load monitoring susceptance was found to be effective. This paper summarizes different types of loading effects related to EMI.

Abstract

Specific growth rate of bacteria has been expressed through characteristics influence deposition at various stratums to aquiferous zone. The growth rates of bacteria are under the influence of the substrate utilization that contaminates groundwater aquifers in various formations. Derived mathematical equations generated theoretical values that expressed the rate of exponential phase of ammonia deposition and bacteria growth rate in homogenous formation. Slight fluctuations were experienced in between the aquiferous zones under the influence of variation from degree of porosity and permeability of the stratum. Experimental values were compared with the theoretical values; both parameters produced a best fit. These expressed the application of the derived model that determines partial deposition of ammonia and bacteria growth rate in homogenous formation. The study is imperative because the model expressed partial depositions of ammonia that determine the growth rate of bacteria at various formations to groundwater aquifers in the study area.

Abstract

Evaporation from the open pan as well as surface is a complex phenomenon of the hydrological cycle and influenced by many meteorological parameters, such as rainfall, temperature, relative humidity, wind speed and bright sunshine hours. Measurement of evaporation with accuracy is and continuous is a difficult operation. In such situations, it becomes an imperative to use neural network models that can estimate evaporation from available climatic data and may give more accurate results than the measured pan evaporation. In this regard, a number of models for predicting the pan evaporation have been developed by several investigators for different locations of India and abroad. Most of the current models for predicting evaporation use the principles of the deterministically based combined energy balance – vapor transfer approach or empirical relationships based on climatological variables. This resulted in relationships that were often subjected to rigorous local calibrations and therefore proved to have limited global validity. Due to these limitations the conventionally applied regression modeling techniques need to be further refined to achieve improved performance by adopting new and advanced technique like neural networks. Evaporation process is complex and needs non-linear modeling and hence, can be modeled through Artificial Neural Networks (ANN). Large number of researchers have been established the applicability of artificial neural networks (ANNs) to the problems in agricultural, hydrological, meteorological and environmental fields. The review related to evaporation modeling using neural networks is discussed here in brief.

Abstract

This paper reports of some observations on the type and frequency of oestrous expressions in the red sokoto doe (RSD). There is reduced manifestation of oestrous signs in does kept without males. Presence of males and coitus also does affect the nature and frequency of a given oestrous expression. The presence of a buck combined with cloprostenol (an oestrous synchronizing agent) induction produces intense manifestation of heat in a higher percentage of RSDs.

Abstract

Indigenous goat breeds should be considered as promising genetic resource taking into account that goats comprise a considerable proportion of livestock and contribute substantially to the economic requirement of small scale farmers in Zimbabwe. They are tropically adapted and suited to low input range conditions, furthermore are reputed to give birth every year which may be considered unique characteristic of indigenous goats. In order to improve the average level of indigenous goat breeds for economic valued traits by genetic means the flocks must be subjected to selection for specific traits or combination of traits required. The prime aim of selection is to identify superior animals and use them for breeding so that the efficiency of the flock is improved. Another viable option is crossbreeding where it has been used has a constant feature associated with the introduction of improved goat type breeds into local goat population. Selection and crossbreeding have not been utilized to any extent to improve productivity of local goats and it is highly recommended that if these are to be successful they should be invariably accompanied improvements in management. There is little point in seeking genetic improvement in indigenous goat breeds due to selection or crossbreeding if management and nutrition are inadequate.little point in seeking genetic improvement in indigenous goat breeds due to selection or crossbreeding if management and nutrition are inadequate.

Abstract

A lioness was brought for postmortem at the Wild Animal Rescue Centre, Kodanad Kerala India. The right mammary gland was extremely enlarged and was completely invaded by coalescent yellowish granular masses and whitish connective tissue. Histopathology of the organs revealed proliferation of round or polyhydric mild anaplastic cells, with round hyper chromatic nuclei, evident nucleoli and eosinophilic cytoplasm and with moderate anaplasia. The cells formed solid masses surrounded by fine connective stroma. Mitotic figures were conspicuous and in many areas the tumor cells invaded the blood and lymphatic vessels. There were metastatic changes in the retro-mammary lymph node and other organs of the pelvic, abdominal or thoracic cavities with similar characteristics of primary tumor.

Abstract

This is a review paper that looks at the influence of sign and magnitude of the correlation between direct and maternal genetic effects for growth traits in sheep, goats and cattle. Considerable debate exists about the validity of results on the factors which influence the sign and magnitude of the correlation between direct and genetic effects of growth traits in sheep, goats and cattle. The current reports on sign and magnitude of the correlation between direct and maternal effects for growth traits in sheep, goats and cattle show that both positive and negative values are possible. It emerged that the use of an appropriate covariance of direct and maternal genetic effects for growth traits in sheep, goats and cattle has a bearing on the accuracy of selected programs. The importance of the correlation between direct and maternal effects for growth traits in sheep, goats and cattle is based on the notion that ignoring the covariance of direct and maternal genetic effects for growth traits in sheep, goats and cattle may distort the ranking of individual animals in a population. The review paper, therefore, concludes that the sign and magnitude of covariance of direct and maternal genetic effects for growth traits in sheep, goats and cattle, is dependent on various factors which include management, breed and data preparation process.

Abstract

Citrus is the main fruit group grown in tropical as well as sub-tropical climate of more than 150 countries in the world. Irrigation scheduling and water requirement of the citrus crops are one of the main concerns of the modem citrus fruit production irrespective of availability of natural resources. A large number of research findings have emerged world over on irrigation scheduling and water requirements of the citrus based on available soil water content and its depletion and based on pan evaporation replenishment. The research review of the literature has revealed best promising results on irrigation scheduling based on depletion patterns of soil available water content, irrigation schedules of various citrus crops and fertigation. Irrigation water management with proper water use is one of the prime concerns of modem horticulture irrespective of soil and water resource availability. A variety of recommendations have reviewed the world over on irrigation scheduling based on analysis of meteorological parameters, evapo-transpiration, depletion of available water content, soil and leaf water potential. The review of the literature has revealed best promising results on irrigation scheduling based on depletion patterns of soil available water content. Similarly, irrigation scheduling has shown good responses on growth, yield, and quality compared to calender method of irrigation schedules. The present status of the review of irrigation scheduling and water requirement of citrus cultivars is clearly presented in this research review article.

Abstract

This study investigated the patterns and scope of investment by cooperative organisations in rural communities of Kano state. It specifically examined the patterns of cooperative investment, Scope of investments of cooperative organisations; Impact of cooperative activities on rural community development, obstacles militating against the effective operations of cooperative organisations. The research design was based on the main tenets of descriptive survey. The sample of the study was 320 participants selected from fourty cooperative societies. It was made up of 200 (72%) males and 120 (23%) females. Three instruments were used to collect data, demographic questionnaire, Questionnaire for members and focus group discussions. The data collected in this study were subjected to chi-square test and descriptive (frequency count). The findings revealed that production is the dominant pattern of cooperative investments, while processing, consumer and multi purpose are also patterns of cooperative investments. The scope of investments of cooperative organization was that Loans to small scale trades, workers loans, commercial activities and agriculture. There was a significant differences in the expressed opinions with regards to how the activities of cooperative organisations are implemented some of the respondents are of the opinions that it is very well, and some said it is some how and others said it is not effective. It was also observed that the activities of cooperatives have impacted positively on the lives of the rural people. Based on these findings it is recommended that there is the need to educate the members in order to enhance their capacity for optimum results, Government should devise a better way for supervising the activities of cooperative organisations and also provide an enabling policy. Cooperative organizations should be organizing adult literacy classes for their members in order to reduce the level of illiteracy in the community and serve as pressure groups.

Abstract

Body weight is an important attribute in animal production as it forms the basis for not only assessing growth and feed efficiency but also in making economic and management decisions. The major focus of this review is to look at bioprediction of body weight and carcass parameters from morphometric (linear body) measurements in livestock and poultry production. There is a consensus amongst researchers working with different livestock and poultry species that morphometric characteristics could serve as predictors of body weight and carcass parameters. Different studies have exploited correlations of morphometric measurements with body weight and carcass parameters to develop techniques for estimating body weight and carcass parameters in different livestock and poultry species, where weighing scales may not be available. The review highlights some of the factors which may influence the accuracy of prediction of body weight and carcass parameters using regression models. Categorization of data according to sex and age is necessary to improve prediction power of equations. The estimation of body weight using morphometric measurements becomes very useful in smallholder livestock and poultry producers who rarely keep birth records. Measurements of various morphometric traits are of value in estimating body weight and carcass parameters in livestock and poultry production and because of the relative ease in measurements they can be used as an indirect method of predicting body weight and carcass parameters. These will provide good information on performance, productivity and carcass characteristics of livestock and poultry. The review concludes that there is need to develop different predictive equation for various species since different species have different relationship between linear body measurements with body weight and carcass parameters. The use of morphometric measurements to predict body weight or carcass parameters would overcome many of the problems associated with visual assessment or evaluation.
