Investigation of the utilisation of social networks in e-learning at universities

Over the years universities have considered to use social networks for learning purposes as most of their students now engage on them. However, questions on the impact social networks would have on learning and how they can be utilised further for more effective teaching and learning are still unclear. To solve these questions, an in-depth investigation has been conducted to understand the benefits and drawback of social network features available for students. The investigation results show that students strongly believe that social network features will help enhance learning and the key ways of utilising such features have been suggested

Applications of adenine nucleotide measurements in oceanography

The methodology involved in nucleotide measurements is outlined, along with data to support the premise that ATP concentrations in microbial cells can be extrapolated to biomass parameters. ATP concentrations in microorganisms and nucleotide analyses are studied

Diabetes knowledge, beliefs and practices among people with diabetes attending a university hospital in Karachi, Pakistan

A structured questionnaire on knowledge, beliefs and practices regarding diabetes was administered to 199 persons with diabetes (92.5% type 2) attending the Aga Khan University Hospital, Karachi. Mean age [standard deviation (SD)] was 53 (11) years. Mean duration of diabetes (SD) was 8 (7) years in men and 9 (6) years in women. Men had a significantly better knowledge score than women (P = 0.02); there was no significant difference in the beliefs and practices scores. Scores were classed as good (\u3e 60%) in only 13.6% of participants for knowledge, 17.6% for beliefs and 11.2% for practices. About 38% of the participants had received education on diabetes care

Use of 2,4-dichlorophenoxyacetic acid (2,4-D) to facilitate bacterial infection of roots

2,4-dichlorophenoxy acetate (2,4-D) is a commonly used herbicide for the control of broad-leafed weeds in wheat, maize and rice. Its auxin-like action has been extensively exploited for induction of roots in plant tissue cultures. Over the past few years, however, 2,4-D has become focus of attention because of its potential to modify plant roots vis-à-vis bacterial infection. This role of 2,4-D has immense significance in understanding the mechanism of legume-Rhizobium symbiosis and extending this phenomenon to cereal crops. The need to make the plant roots harbour bacteria (particularly those capable of fixing atmospheric nitrogen) and the role of 2,4-D in facilitating the process has been reviewed.&nbsp

Using SERVQUAL for assessing and improving patient satisfaction at a rural health facility in Pakistan.

A cross-sectional study of Patient satisfaction with care was conducted over a period of 1 year from March 2004 to March 2005 in a secondary-level hospital in a peri-urban area of Karachi, Pakistan. Using the SERVQUAL tool and exit interviews, data were collected quarterly from a total of 1533 Patients. Results sharing and capacity-building workshops were arranged during the 4 phases of the survey to sensitize the staff of the hospital to work towards improving Patient satisfaction. The level of satisfaction of the Patients with the outPatient health services provided showed a gradual increase from 34.4% to 82.0% over the 1-year period
