Population growth, trophic level, and some aspects of reproductive biology of two congeneric archer fish species, Toxotes chatareus and Toxotes jaculatrix, collected from Johor coastal waters, Malaysia, were studied. Growth pattern by length-weight relationship (W=aL~b) for the sexes differed, and exhibited positive allometric growth (male, female and combined sexes of T. chatareus; female and combined sexes of T. jaculatrix) and isometric growth (male samples of T. jaculatrix only). Trophic levels of both species were analyzed based on 128 specimens. The results show that, in both species, crustaceans and insects were the most abundant prey items, and among crustaceans the red clawed crab Sesarma bidens and Formicidae family insects were the most represented taxa. The estimated mean trophic levels for T. chatareus and T. jaculatrix were 3.422±0.009 and 3.420±0.020, respectively, indicating that they are largely carnivores. Fecundity of T. chatareus ranged from 38354 to 147185 eggs for females with total length ranging from 14.5 to 22.5 cm and total body weight from 48.7 to 270.2 g, and T. jaculatrix 25 251 to 150456 eggs for females with total length ranging from 12.2 to 23.0 cm and total body weight from 25.7 to 275.0 g. Differences in values of gonadosomatic and hepatosomatic indexes calculated for both species in this study may have resulted from uneven sample size ranges.  相似文献   

The implications of Ramadan fasting for human health and well-being     

Alkandari JR  Maughan RJ  Roky R  Aziz AR  Karli U 《Journal of sports sciences》2012,30(Z1):S9-19

Islamic Ramadan is a 29-30 day fast in which food, fluids, medications, drugs and smoking are prohibited during the daylight hours which can be extended between 13 and 18 h · day(-1) depending on the geographical location and season. The majority of health-specific findings related to Ramadan fasting are mixed. The likely causes for these heterogeneous findings lie in the amount of daily time of fasting, number of subjects who smoke, take oral medications, and/or receive intravenous fluids, in the type of food and eating habits and in changes in lifestyle. During Ramadan fasting, glucose homeostasis is maintained by meals taken during night time before dawn and by liver glycogen stores. Changes in serum lipids are variable and depend on the quality and quantity of food intake, physical activity and exercise, and changes in body weight. Compliant, well-controlled type II diabetics may observe Ramadan fasting, but fasting is not recommended for type I, noncompliant, poorly controlled and pregnant diabetics. There are no adverse effects of Ramadan fasting on respiratory and cardiovascular systems, haematologic profile, endocrine, and neuropsychiatric functions. Conclusions: Although Ramadan fasting is safe for all healthy individuals, those with various diseases should consult their physicians and follow medical and scientific recommendations.  相似文献   

Determinants of library's effectiveness and efficiency: A study of collection development, organization and services of Maulana Azad Library, AMU (India)     

Abdul Mannan Khan  S. Mustafa ZaidiAuthor vitae 《Library Collections, Acquisitions, and Technical Services》2011,(4):95-105

The study is focused on users' opinion as regards the adequacy of library collection and analyzes the level of users' satisfaction about library collection, organization, facilities and services both traditional as well as, IT enabled services. A well structured questionnaire was administered to faculty members, research scholars and students of the AMU to collect data regarding the adequacy of library collection and analyze the level of users' satisfaction. The survey reveals that the library collection in the AMU library is adequate enough for their users. AMU library users were also satisfied with the existing infrastructure of library and organization of their collections. The researcher observed that the overall satisfaction levels of the users regarding the AMU library is good.  相似文献   

Knowledge sharing practices: A case study at Malaysia’s healthcare research institutes     

Ramlee Abdul Rahman 《International Information and Library Review》2011,(4):207-214

The main objective of this study was to investigate the perception of the researchers and officers within the National Institutes of Health Malaysia (NIH) about their understanding of knowledge sharing practices in their respective environment. Questions included: what are the perceptions of the respondents with regard to the knowledge sharing practices in their respective institutions? What are the benefits for knowledge sharing practices as perceived by them? What are their perceived organisational knowledge sharing practices motivating factors? Also, what are the hindering factors? The survey of the researchers and officers of the NIH was distributed to 400 respondents from the six research institutes under NIH: Institute for Medical Research (IMR), Institute for Public Health (IPH), Network for Clinical Research Centres (CRC), Institute for Health Management (IHM), Institute for Health Systems Research (IHSR) and Institute for Health Promotion (IHP). The responses indicated that knowledge sharing depends on the context of encouraging and rewarding the practices of organisational knowledge sharing. The findings suggest four factors – Environment and Infrastructure, Management Support, Culture and Technology – as significant determinants in influencing the organisational knowledge sharing practices among the employees. The study was limited to the perceptual aspect of the issue, specifically from the individuals’ opinions and sentiments.  相似文献   

Understanding the emergence of females as leaders in academia: The intersections of gender stereotypes,status and emotion     

Nurdiana Gaus  Nasrullah Larada  Syakir Jamaluddin  Muhammad Azwar Paramma  Abdul Karim 《Higher Education Quarterly》2023,77(4):693-708

Drawing on the expectation state theory, this paper seeks to analyse the social cognitive process of the impacts of gender stereotypes along with their culturally derived schemas of status belief, status characteristics and emotion at the early stage of women's endeavour to emerge as leaders in academia. Employing a convenience sampling and interviews held with five women academic participants from three public and private universities in the western region of Indonesia, this research reveals that two social cognitive practices affect women's endeavour to emerge as leaders; (1) the incongruities of cultural and cognitive expected status belief and status characteristics about females with the expected performance of leadership. The pervasive effect of these can be mitigated when women adopt a strategy of neglection, coupled with a strategy of networking both via their own networks and their husband's networks; (2) the incongruities of cultural and cognitive expected ways of emotional expression on women with the expected performance of leadership. This impacts the status conferral that shapes the worthiness of females to emerge as leaders, leading female leaders in our study to build a protective shield of emotion display to keep them perceived as worthy individuals for leadership roles.  相似文献

Convection-radiation from a continuously moving fin of variable thermal conductivity     

Abdul Aziz 《Journal of The Franklin Institute》2011,348(4):640-651

The homotopy analysis method (HAM) is applied to generate an analytic solution for heat transfer in a moving fin of variable thermal conductivity which is losing heat by simultaneous convection and radiation to its surroundings. The accuracy of the analytic solution is validated by comparing it with the direct numerical solution of the problem. The analytic solution is found to be accurate to at least three places of decimal for a wide range of values of the parameters that are commonly encountered in thermal processing application. Graphs displaying the results are interpreted in physical terms.  相似文献
