Leisure Time Physical Activity (LTPA) among female academicians in Universiti Putra Malaysia

Background: Leisure time is an important domain in life regardless of gender, social class and age. The objective of this study was to determine the pattern LTPA (Leisure Time Physical Activity) among female academicians in Universiti Putra Malaysia (UPM). Materials and Methods: A cross-sectional study was conducted among female academicians in UPM, from December 2014 to March 2015. Respondents were randomly chosen by simple random sampling using IBM-SPSS version 22 software. A validated and reliable questionnaire was used for data collection. It consisted of five sections involving socio-demographic factors, time constraints (home and work place), physical activity, accessibility to leisure-related facilities (home and work place) and health status. Descriptive analysis, t-test, correlation and multivariate linear regression were employed to determine the predictors using enter method. The data was analysed using SPSS version 22.0 software. Result: A total of 654 respondents participated in the study yielding a response rate of 75%. The top five (5) physical activities with the highest level of involvement were evening walking 0.90±1.25; jogging 0.48±0.96, playing golf 0.14 ±0.52 and swimming 0.31±0.71. While, the five (5) least common physical activities reported were yoga 0.08±0.40, dancing zumba 0.18±0.57, aerobics 0.14±0.48, playing tennis 0.15±0.48 and cycling 0.21±0.55. There was a significant association between leisure in physical activity with time constraints at home (t=5.023, p<=0.001), time constraints at work place (t=-3.199, p<=0.001), health status (t=-6.363, p<=0.001) and accessibility to leisure- related facilities at home (t=-4.348, p<=0.001). No association was shown between leisure in physical activity and accessibility to leisure-related facilities at work place (t=0,947, p=0.344). Multiple Linear Regression analysis showed the predictors of physical activity were age ((B= -0.107, p<=0.001), facility at home (B=-1.030, p=0.002) and health status (B=-1.550, p<=0.001). Conclusion: The findings from this study showed that, female academicians were physically inactive; however several factors influenced this physical inactiveness

A novel algorithm to form stable clusters in vehicular ad hoc networks on highways

Abstract Clustering in vehicular ad hoc networks (VANET) is one of the control schemes used to make VANET global topology less dynamic. Many of the VANET clustering algorithms are derived from mobile ad hoc networks (MANET). However, VANET nodes are characterized by their high mobility, and the existence of VANET nodes in the same geographic proximity does not mean that they exhibit the same mobility patterns. Therefore, VANET clustering schemes should take into consideration the degree of the speed difference among neighboring nodes to produce relatively stable clustering structure. In this paper, we introduce a new clustering technique suitable for the VANET environment on highways with the aim of enhancing the stability of the network topology. This technique takes the speed difference as a parameter to create relatively stable cluster structure. We also developed a new multi-metric algorithm for cluster-head elections. A simulation was conducted to evaluate our method and compare it with the most commonly used clustering methods. The simulation results show that our technique provides more stable cluster structure on the locale scale which results in a more stable network structure on the global scale. The proposed technique reduces the average number of clusters changed per vehicle by 34-46%, and increases the average cluster lifetime by 20-48% compared to the existing techniques

Prospek Pengolahan Hasil Samping Buah Kelapa

Prospect of Coconut By-Product ProcessingCoconut meat is the main component of coconut, while the coconut husk, shell, and water are considered as by-product. With the coconut production in Indonesia at average of 15.5 billion coconuts per year, the total by-product is accumulated to 3.75 million tons coconut water, 0.75 million tons shell charcoal, 1.8 million tons coconut fiber, and 3.3 million tons coir dust. Business in coconut by-product processing is condidered to be prospective as long as it is planned and managed properly. Based on the financial analysis in 2004, the B/C and IRR of coconut husk processing into coconut fiber and coir dust for 10 years were 3.58 and 76%, coconut shell into shell charcoal for 5 years was 1.11 and 23%; and coconut water into nata de coco for 5 years was 1.32 and 32%. The industry of coconut by-product processing should be supported by technical feasibilty, mainly the raw material availability, market, and appropriate coconut husk machinery. To provide sufficient raw material for coconut husk processing, it needs about 300 ha of coconut plantation. Furthermore, to abtain additional farmer's income the coconut husk processing should be integrated with coir dust processing into compost, so that it can earn additional income. To produce one ton of coconut fiber will produce 5 tons of coir dust. It suggested that the location of coconut by-product processing is better closed to the raw material source, and to secure the continuity of rawmaterial supply and product marketing the business should be run in the form of cooperation

Effects of different types of feeds on growth and production of tiger shrimp, Penaeus monodon at Bagerhat region, Bangladesh

An experiment was carried out in farmers' gher (shrimp farm) at Bagerhat sadar upazilla, Bagerhat to ascertain the effects of three different types of feeds on the production and economics of brackishwater shrimp, Penaeus monodon for a period of 120 days. There were three treatments such as T1 (BFRI dough feed containing of 30% fish meal, 10% protein conc., 10% soya meal, 15% mustard oil cake, 18% rice bran, 5% maize, 10% wheat flour, 1% oyster shell powder and 1% vitamin premix), T2 (Commercial diet Saudi-Bangla grower) and T3 (Saudi-Bangla special feed). Each treatment had two replicates and the stocking of shrimp in each gher was 3 nos/m². Water quality parameters did not differ significantly among the treatments except water depth. Average production and net return of shrimp in different treatments varied from 404.0 to 509.0 kg/ha and Tk. 56,493.99-Tk. 84,209.60, respectively. T2 showed significantly (p<0.05) the highest production and economic return. The result of the study implied that T2 is more suitable and economically viable than that of other treatments for shrimp farming
