Pakistan Journal of Biological Sciences , 2001,
Abstract: The objective of the investigation was to evaluate the performance of different dairy breeds offered same ingredient, same amount of concentrate mixture and almost same amount of roughage under farm condition. Nine mid-lactating cows of three different dairy breeds were grouped into 3 diet treatments according to their genotype, T1 (Pabna breed), T2 (Sindhi cross) and T3 (Jersey cross). Average daily dry matter (DM) intake by the cows fed on T3 diet (7.23) was slightly higher than that of cows fed on diet T2 (7.20) or T1 (7.18). T3 treatment group showed higher (p<0.01) milk production (5.0) followed by T2 (3.71) and then T1 (2.78). The live weight gain (kg d -1) was highest (0.232) in Jersey cross (T 3) and lowest (0.134) in Pabna cows (T1). The difference of weight gain among different treatment groups was statistically significant. Specific gravity of milk of T2 (1.031) and T3 (1.031) groups were similar but non-significantly higher than T1 (1.029). The production of total solids (g kg -1) was higher in T1 group (139.90) than other two groups but the difference was statistically non-significant. The cows of T1 group produced significantly higher solids-not-fat (88.53 g kg -1) in their milk than other two groups. Fat production by Pabna cows (T1) was non- significantly about 4.7 and 8.2% higher than that of other two groups T2 & T3 respectively. Milk protein present in Pabna cows milk (38.10 g kg 1) was comparatively higher than that of T3 (37.78) or T2 (37.57) cows. The energy value (3.57) of milk of Pabna cows was also non-significantly higher than that of T2 (3.45) and T3 (3.33). Lowest feed cost for per liter milk production (Tk. 6.10) was found in Jersey cross (T3) and highest (Tk. 10.88) in Pabna cross (T1). There was much difference in the values of per liter milk production among the treatment groups.

Md. Abdur Rashid,Md. Shahadat Hossain,M.H. Kawsar
Pakistan Journal of Biological Sciences , 2001,
Abstract: Nine indigenous bull calves of about 2 years old were divided into 3 groups (3 animals in each). Three rations (A,B & C) were supplied to these groups randomly. The aim of investigation was to evaluate the effect of different rations on the performance of bull calves. Total dry-matter (DM) intake (kg/d) of the animals fed on diet B (2.42) was higher than that of other two. Digestibility of DM was similar in all three cases. Digestibility values for crude Protein (CP) and Ether extract were higher in treatment B group significantly (P<0.05) than the other two groups. Digestibility of crude fibre (CF) was higher in treatment A and B groups than that of C. Treatment group B also showed higher live weight gain (152 g/d) than that of group C (115 g/d) and group A (107/gd). The differences were statistically significant (P<0.01). Feed efficiency of diet group B (16.61) was also showed statistically higher (P<0.05) than that of treatment group C and treatment group A.

Journal of School of Public Health and Institute of Public Health Research , 2008,
Abstract: Backgrounds and Aim: Increased life expectancies and decreased fertility rates have led to ageing populations worldwide. This phenomenon is one of the most important public health challenges of the current century. Previous studies have shown that identifying factors affecting lifestyle and educational needs help in designing new strategies for health promotion. This study was conducted to investigate the preparedness of the elderly to adopt a healthy lifestyle and factors affecting it in the City of Tehran in 2007. Materials and Methods: This qualtative study included 60 elderly persons from Tehran elderly centers, using the focus group discussion method. Sampling was targeted and a qualitative methodology was used for analysis of the data collected. Results: The results shows that different elderly persons have different views with regard to what physical and mental health is and what factors cause healthiness. They believe that regular physical activity is very beneficial but that there are many difficulties in performing regular physical activity. Most of the subjects are in the prepation, action and maintenance stages as regards physical activity. On the other hand, nearly all the subjects are in the precontemplation stage with regard to fruit and vegetable consumption, despite the many obstacles in following a healthy diet.Conclution: The findings of this study show that many factors influence adoption of a healthy lifestyle by the elderly. Bearing these factors in mind, appropriate educational strategies aiming at facilitating adoption of a healthy lifestyle can be designed.

Abstract: Two people are required to operate current superbike paddock stands in order to elevate the superbike. Lifting the superbike alone using the current design of paddock stand may be impractical and inconvenient for users. To overcome this limitation, a new design of a superbike paddock stand was conceived that could be operated by a single user. CAD and CAE tools using CATIA V5R18 software were utilised in designing this new stand. A 3D CAD model was developed and analysed through finite element analysis (FEA) and a prototype fabricated for verification testing of the design. The use of CAD and CAE tools saved much time in the design work and gave the researchers and designers freedom in producing their own design. However, the most important aspect of this design study was to design a superbike paddock stand that is more practical and convenient for operation by a single user.

Pakistan Journal of Biological Sciences , 2004,
Abstract: In the present study the evaluation of the adoption status of artificial insemination (A.I.) technology in 5 villages of Mymensingh district in Bangladesh. Evidence showed that the proportion of households rearing cattle was 47.17%. Forty four percent of those households have adopted the A.I. technology. The proportion of cross-bred cattle population was about 34%. It varied among farm sizes, herd sizes and categories. The distribution of cattle holdings over the households was less unequal than the distribution of land holdings; but there was very little difference between the distribution of cattle and cross-bred cattle holdings.

Biotechnology , 2002,
Abstract: Four different media namely- Hyponex, Murashige and Skoog (MS), OKF1 and Knudson C (KC), were tested for large scale multiplication of sympodial native orchid, Dendrobium transparens Wall. via seeds. MS medium was found to be best for characters studied in Dendrobium transparens, followed by Hyponex medium but OKF1 medium gave the least performance. Days required to seed germination was the minimum (50 days) in MS medium while the maximum days (59 days) was required by OKF1 medium. Considering other characteristics, such as days required to protocorm formation and plantlet development, number of leaves and roots per plantlet, plantlet height and root length and finally plant survivability percentage, MS medium showed significantly better performance for in vitro seed propagation of Dendrobium transparens.

Pakistan Journal of Biological Sciences , 2002,
Abstract: An experiment was carried out at the net house of the Department of Agronomy, Bangladesh Agricultural University, Mymensingh using four seedling ages 30, 45, 60 and 75 days, for transplant rice during July to November 1995 in transplant Aman (T. Aman) season and during November 1995 to May 1996 in Boro season. The highest grain yield was obtained from 45-days old seedlings in both seasons. Regression models prepared for T. Aman and Boro seasons separately could explain the yield variations 77.1% and 68%, respectively due to seedling age.
Use of Neem Extract in Controlling Root-knot Nematode (Meloidogyne javanica) of Sweet-gourd
L. Yasmin,M.H. Rashid,M. Nazim Uddin,M.S. Hossain
Plant Pathology Journal , 2003,
Abstract: Extract of neem (Azadirachta indica.L) seed was used to control the root knot nematode Meloidogyne javanica of sweet gourd. Extract of neem seed was found to be leathal to the juvenile of M. javanica compared to the extracts of bark and leaf of neem. Pot experiment with standard `S` concentration of all the extracts both in side drench and root-dipping methods appeared to give significant suppression in root galling, L2 and L3 population of the nematode. Identical response among the treatments with respect of plant growth characters was attributed to the synthesis of less toxic metabolites in the immature neem seeds used in the study. Positive correlation between gall number and eggmass indicated higher activity of the nematode allowing more adult females to develop with the production of increased number of eggmasses.
