In current world, usage of the Internet and Information Communication Technology are increased rapidly. Almost every valuable and confidential information is stored in computers or computer based systems and majority are sharing their personal information in social networks such as Facebook. There is a significant growth of the computer based or online criminals in all over the world due to the evolution of the information and communication technology. Criminals involved in murder, kidnapping, sexual assault, extortion, drug dealing, economic espionage & cyber terrorism, weapon dealing, robbery, gambling, economic crimes, and criminal hacking e.g. Web defacement and theft of computer files, maintain files with convicting evidence on their computer.\n\nDigital forensic is part of forensic discipline that absolutely covers crime that is related to computer technology. Computer forensic was created to address the specific and articulated needs of law enforcement to make the most of this new form of electronic evidence. “Computer forensic science is the science of acquiring, preserving, retrieving, and presenting data that has been processed electronically and stored on computer media”.\n\nThis paper demonstrates an Introduction to computer forensics, Use of computer forensics, Issues facing computer forensics, Legal aspects of forensics and applicable in the context of Sri Lanka.

Plant-essential oils have been considered as an important source of bioactive molecules like antimicrobials, analgesics, anti-inflammatory and anti-cancerogenic agents. The role of free fatty acids in biological functions of Capsicum plant extracts is unknown. We obtained organic fractions of unripe and ripe fruits of Capsicum chinense Jacq. Cv. Jaguar and Criollo after hexane-batch extraction. We tested organic extracts for antimicrobial activity against Gram-negative bacterial strain Escherichia coli (ATCC 25922), Gram-positive bacterial strains Enterococcus faecalis (ATCC 29212), Staphylococcus aureus (ATCC 25923) and Staphylococcus epidermidis (ATCC 12228), and yeast Candida albicans (ATCC 90028). We found that extracts from ripe fruits of both cultivars had higher antimicrobial activity than unripe ones. Implication of numbered free fatty acids on observed antimicrobial activity are discussed.

The present work was conducted to assess the physiological response of onion plant to GA3 at Sher-e-Bangla Agricultural University, Bangladesh in the open environment under natural sunlight during the period from October 2014 to March 2015. GA3 at levels of 0, 20, 40 and 60 ppm were used with the onion by laid out in a Randomized Complete Block Design with three replications. The factor levels of GA3 which were applied during transplanting by root soaking, and foliar spray at 30 and 60 days after transplanting. GA3 has a great effect on increasing vegetative growth, shoot biomass, bulb biomass and also dry matter accumulation in onion plant compared to control. Insignificant effect by all concentration of GA3 was found in bulb length, fresh root biomass, and dry root biomass. Thus, the use of 60 ppm GA3 was better compared to the other three concentrations and significantly increased the fresh bulb biomass about 42.96 % over control. It is concluded from this study, GA3 @ 60 ppm can be used to bring the improvement of onion production from the economic point of view.

The effectiveness of on-the-job training has been the focus of many researches in the area of training. It has been known as important to many business organizations. The focus of the present study is to find out if OJT is used in Saudi business organizations as training type to improve the KAS of employees. Thirty general managers and thirty HR managers were part of the sample group. The following research questions were studied: (1) Do companies in Saudi Arabia conduct on-the-job training to their employees as an organizational HR policy? (2) Do on-the-job training efforts of some companies in Saudi Arabia have shown effectiveness as perceived by the HR managers and general managers? (3) What are these perceived changes? and (4) What factors brought about the perceived success of on-the-job training in Saudi Arabia? The findings show that Saudi business organizations conduct on-the-job training to its employees as an organizational HR policy; HR managers and general managers perceive OJT as effective in effecting positive changes in the knowledge, attitudes and skills (KAS) of employees; changes include: increased knowledge, improved skills, and developed right attitudes toward work of trainees; and there are factors in the training that help in making the OJT successful such as: designing training that have appropriate objectives and assessment measures to the needs of the trainees and the organization, skilled trainers, appropriate and useful methods or processes, encouraging training preview and the trainee’s willingness to undergo training.

This contribution delivers theoretical analysis of the process and relevant findings related to the above process. Design solutions on used metal sheet holders for forming are presented in this article. In the experimental part we conducted laboratory tests using sheet metal samples. This contribution is complemented with discussion on the presented issue.

The aim of this paper is to analyze, following a theoretical framework, the scientific language used in the DSM-5 to diagnose “mental disorders”. In particular, the concepts of “science of mental disorders” and “scientific progress” are investigated and the epistemological and operative implications of their use are introduced, covering the fields of psycho-social sciences. Arguing from a interactionist theoretical perspective, for the first set of implications, the concepts of a-theoretical, objective and neutral, evidence-based research and the tools used in order to pursue diagnostic validity and reliability are analyzed. For the second set, some consequences of the use of such concepts in the work of mental health professionals with their patients, are highlighted. In conclusion, some considerations about the relationship between the object of study, epistemological references and practical instruments are expressed.
