Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1102614
It is important for knowledge workers in the business sector to have access to information on companies, countries, investment opportunities, and projects. Survey of information finding practices of professionals in Kuwaiti companies showed that use of web sites, internal reports, and consulting with colleagues were preferred approaches for finding work related information. Business professionals also frequently used organizational sites, reports from financial analysts, business information services, and social media in seeking information. They listed lack of adequate information in databases and non-availability of information related to local financial situation as barriers to effective information finding. They considered their information finding skills as reasonable but wanted to get more training in searching online databases and web-based sources. The study showed that business organizations ought to make arrangements that frequently used sources were accessible to their employees on regular basis. It is also desirable that training in information skills is arranged by for enhanced information literacy at work.

Knowledge workers in health care can function well in their clinical and professional practice if they have adequate computing capabilities and they apply them optimally in their work setting. Health information systems (HIS), patient health records (PHR), health databases, health portals, etc. are becoming the essential work-context for these knowledge workers. These professionals have to be equipped with relevant IT competencies in order to be usefully functional, productive and value-driven. HIS was implemented in 2006 in one of the major public hospitals in Kuwait. Thus far the system is partially functional and many of its strengths are not adequately exploited. The Purpose of this study was to examine whether health professionals possess needed computing capabilities and what role did these play in the optimization of the HIS. We conducted a survey administering a questionnaire to a stratified random sample of 210 knowledge workers. We received 130 responses and analyzed data using 124 of the usable responses. In this paper we have reviewed perceptions about the computing capabilities of these professionals, inadequacies they had reported, problems they had encountered, and the role of IT unit in the organization.

Seeking insights of stakeholders is an important element of the needs assessment process for starting a doctoral program. This paper reports a study that reviewed the perspectives of stakeholders with regard to a PhD in information studies. Feedback from major stakeholders was sought using a combination of qualitative and quantitative methods: a web-based survey of 180 relevant stakeholders (including current master students, alumni of the department, faculty members and working information professionals) followed by a focus group discussion with 7 faculty members from Kuwait University and Public Authority for Training and Education. Findings showed that there was a need for starting a PhD program in information studies at Kuwait University. Data also provided important insights about the structure of the proposed program, its content, areas of coursework and specializations. Results of the study might be useful for developing a PhD program in other universities. The findings are also expected to provide guidelines for conducting needs assessment for doctoral programs in information studies.

Bangladesh produces a huge amount of potatoes every year. This research was carried out to find the optimum conditions for bioethanol production from potato of Bangladesh. From this study, optimum growth of yeast (Saccharomyces cerevisiae CCD) was observed at pH 6.0 and temperature 31°C. Addition of a small amount of alpha-amylase enzyme to potato solution was found to enhance the potato starch degradation and made the fermentation process quicker. This study observed that 1750 unit alpha-amylase is enough to degrade the starch in 15% of 500 ml potato starch solution. From fermentation time study, 6-day incubation time was found to be enough to complete the fermentation process and optimum production of bioethanol form potato starch. Suitable concentration of potato in fermentation process was determined using five different potato solutions (5%, 10%, 15%, 20% and 30%). A highest production of bioethanol was found in  20% potato treatment. Therefore, 20% potato solution is recommended for high-scale production of bioethanol from potato starch.

Abstract: A research project was carried out aimed at to study the toxic effects of Palpoluck Polygonum hydropipper L. and Bhang Cannabis sativa L. crude extracts against two species of termites i.e. Heterotermes indicola (Wasmann) and Coptotermes heimi (Wasmann) at Nuclear institute for Food and Agriculture (NIFA) Peshawar, Pakistan in April 2002. Results revealed that after ten days of feeding maximum percent mortality in case of Polygonum hydropipper L. leaf and flower extracts was 28.0, 52.0, 28 and 74.7 for H. indicola and Coptotermes heimi respectively, while in control only 10.7 and 12.0% mortality were recorded. Similarly, for the same species of termites the percent mortality in Cannabis sativa L. extracts was 54.7, 64.0, 58.7 and 70.7 for leaf and seed extracts respectively, while in control only 12.0 and 10.7% mortality were observed. In each extract mortality was significantly different from that of control. Toxic effects of both extracts (leaf and flower) were more profound against Coptotermes heimi than Heterotermes indicola during these ten days of feeding. Also the seed extracts caused more mortality than the leaves for both species, suggesting the availability of high contents of toxic materials in seed.

Songklanakarin Journal of Science and Technology , 2006,
Abstract: Chrysoperla carnea (Green lacewing) is voracious predator of insect eggs and varieties of soft-bodied arthropods such as caterpilllars, aphids, jassids and mealy bugs. It is currently mass-reared and used in biological control of insect pests. Experiments were conducted to find out a better and cheaper artificial diet for mass-rearing of adult C. carnea. Three adult diets were tested in the laboratory conditions in comparison with standard diet; that was mixture of yeast extract, casein, honey, sugar and distilled water. Parameters were fecundity, larval period, pupal period and adult longevity. The results revealed that the mixture of egg yolk, milk and honey was better than all other diets.

Abstract: Study was conducted to determine the effects of various land configurations on dry matter production, distribution and growth of garlic. Ridge planting method significantly influenced total dry matter (TDM) production and its distribution into root, stem and leaf. It had higher total, stem, root and leaf dry matter, leaf area index (LAI) and crop growth rate (CGR) over furrow and flat methods of planting. Varietal difference in dry matter partitioning and growth of garlic was revealed in this study. The cv. Faridpur that had highest clove weight produced higher total, stem, root and leaf dry matter, LAI and CGR over the other two cultivars.

Md. Shahidul Haque,Md. Abdus Sattar,M. Habibur Rahman Pramanik
Pakistan Journal of Biological Sciences , 2002,
Abstract: A field experiment was conducted to study the effects of ridge, furrow and flat planting methods on performance of three cultivars of garlic. Plant height was significantly affected and plants on ridges had the maximum height. Individual bulb weight, bulb diameter and 100 cloves weight were significantly higher in ridge method compared with other two methods. While, the number of cloves per bulb was higher in furrow method. The higher individual bulb weight, bulb diameter and 100 cloves weight of the plants grown in ridges gave a corresponding higher yield of garlic. Among the cultivars, cv. Faridpur had significantly higher individual bulb weight, bulb diameter, 100 cloves weight and a corresponding higher yield. However, it had few cloves per bulb compared with other two cultivars. Planting in ridges has potential application for the yield improvement of garlic.

Abstract: In clinical studies, longitudinal and survival data are often obtained simultaneously from the same individual. Linear mixed effects models are widely used for analyzing longitudinal continuous outcome data, while survival models are used for analyzing time-to-event data. It is a common practice to analyze these longitudinal and time-to-event data separately. However, when multivariate outcomes are obtained from a given individual, they can be correlated by nature, and one can attain considerable gain in efficiency by jointly analyzing the outcomes. An objective of this study is to analyze such multivariate data by jointly modeling longitudinally measured continuous outcomes and time-to-event data. In this joint modeling, we formulate a joint likelihood function for both outcomes and use the maximum likelihood method to estimate the parameters in the two sub-models (longitudinal and survival models). We demonstrate the merits of joint modeling by considering a joint analysis of longitudinally measured serum albumin (biomarker) and time-to-all-cause mortality data obtained from a hemodialysis (HEMO) study. This HEMO study was a large NIH (National Institute of Health) sponsored multicenter clinical trial contrasting the effects of dialysis dose and dialysis membrane permeability in end-stage renal disease patients receiving hemodialysis. We find that the parameter estimates obtained under joint modeling of HEMO data are more efficient than those obtained under separate modeling of the outcome variables.
