Testing is the process of detecting errors present in a system with the given sample input. Risk is the vulnerability associated with the system and the type of testing which uncovers it is called security testing. Risk analysis is the process of determining the level of risk with the available information. Risk-based testing comprises of risk analysis, which is a part of model based testing and involves risk assessment. Risk analysis and security testing can be combined in two ways namely: Risk-driven Security Testing (RST) and Test-driven Security Risk (TSR) analysis.

The study aimed to establish the socio-cultural determinants of fertility among Matengo and Mwera in Mbinga District and to investigate how the differences in the modes of life reflect the variations in fertility between them. The sample used was women aged 15-49 years, and men aged 18 years and above, with a sample size of 141 respondents. Data were collected through interviewing and documentary review. Tables and cross tabulation, and graphs have been used for data analysis and presentation. The analytical frameworks used have been adopted from Davis and Blake, and Bongaarts.

This study is concerned with the coagulation activity of extracts of various rural species. The aim is to ascertain if rural varieties affect coagulation activity. Contents of dry matter and nitrogen are specified in solid samples, and the content of soluble nitrogen is determined in the extracts. These data are used to calculate the efficiency of extraction of nitrogen- containing compounds. The coagulation activity is assessed by jar test using synthetic turbid water, of the initial pH 9and turbidity 35 NTU.

This study looked at the value of educational technology to students. Researchers examined the question “How does the use of smart classroom technology effect the educational achievement of students?” The report includes extensive literature reviews that support the hypothesis that technology does improve certain aspects of the student’s learning pattern. A small study was done focusing on students using assistive technology, either Smart Class or Interactive White Board, to enhance students learning experience. Quantitative and qualitative data was collected and analyzed.

Six protein rich artificial diets were formulated & tested on Apis mellifera colonies during dearth periods. The main components of these diets were Defatted Soy Floor, Parched Gram, Brewer’s Yeast, Skimmed Milk Powder, Protein Hydrolysate Powder, Spirulina, Natural Pollen, Sugar & Glucose Powder. Physico-chemical analysis of diet formulations was carried out to know the exact concentration of various nutrients.

A study was carried out to investigate farmers’ perceptions on the impact of Mushandike dam on livestock dynamics in an initial resettlement scheme, located in a drought prone area. The study focused on farmers resettled in Mushandike resettlement scheme who depend on a dam located upstream in Mushandike Sanctuary, Masvingo. Data were collected through focal group interviews and structured questionnaires that were administered to local farmers and agricultural extension workers. Farmers were selected from the 9 villages in Mushandike resettlement scheme.

Studies were conducted at Regional Research Station, College of Agriculture, Wadura, SKUAST-K, to evaluate the quality of municipal and agricultural waste under aerobic and anaerobic composting. Composting methods with enrichment techniques were adopted with 2 methods (Aerobic & Anaerobic) and 7 treatments in each method. The samples of the aerobic were drawn after 30, 60, 90 and 120 days after composting and in anaerobic compost samples were drawn after 150 days of compost.

Ground water is the only source for irrigation, drinking and domestic purposes in Batticaloa District. This study focused on the characterization of an independent aquifer in three selected GN divisions namely Koduwamadu, Pankudaweli and Veppaweduwan in EravurPattu DS division for its suitability for drinking. Groundwater samples were collected from wells to represent public and individual wells including dug and tube wells in the period of November 2013 to May 2014.

The thermal stability of beta-glucosidase from the land crab digestive juice (Cardisoma armatum) was investigated by studying the effect of heat treatment over a range of 60 to 75 °C. Thermal inactivation of this enzyme, evaluated by loss in activity, was apparently followed by first-order kinetics with k-values comprised between 0.0049 to 0.0391 min-1. D and k-values decreased and increased, respectively, with increasing temperature, indicating faster inactivation of beta-glucosidase at higher temperatures. Ea and Z-values were estimated to 172.98 kJ mol-1 and 12.80 °C respectively.

The different types of seaweeds viz., Caulerpa racemosa, Caulerpa scalpelliformis, Ulva fasciata, Padina tetrastromatica, Stoechospermum polypodioides, Sargassum wightii, Cheilosporum spectabile and Gracillaria edulis were collected and processed for the extraction. The effect of methanol extract of different seaweeds was studied on the larvae of Meloidogyne javanica at different exposure of time (24 hrs, 48 hrs, 72 hrs). The test seaweed extract were taken into two different concentrations (2 mg/ml, 4 mg/ml).
