The ladybird beetles (Coleoptera: Coccinellidae) have great economic importance as natural enemies. Three hundred individuals belonging to 6 genera and 7 species of the subfamily, Coccinellinae and the tribe, Coccinellini was collected during March-May, 2011 from 3 study sites of Hazara University, Garden Campus, Mansehra, Pakistan. They were reported maximum (83.3%) from residential area and minimum (8%) from administration area. All collected species have glabrous hair on their slightly elongated or rounded bright colored body. The seven-spotted ladybug, Coccinella septempunctata (Linnaeus) has maximum (average: 6.7 ± 0.77 cm;n = 15) and Adalia tetraspilota (Hope) has minimum (average: 4.2 ± 0.15 cm;n = 14) body length. Moreover, transverse ladybird, Coccinella transversalis (Fabricius) has maximum (average: 4.8 ± 0.35 cm;n = 10) and Oenopia sauzeti (Mulsant) (n = 9) or adonis ladybird, Hippodamia variegate (Goeze) (n = 10) has minimum (3.1 cm) body width. Except six-spotted zigzag ladybird, Menochilus sexmaculatus (Fabricius) (n = 12), all collected species have black head, varied but attractive and dark in color pronotum and elytra, black scutellum except in fifteen-spotted ladybird, Harmonia dimidiate (Fabricius) (n = 10) which was brownish. The ventral side of body of A. tetraspilota was dark brown, however, C. septempunctata, C. transversalis, H. variegate and O. sauzeti were black;moreover, H. dimidiata was brownish-orange;further, M. sexmaculatus was brown. It is concluded that ladybird beetles of HU have great diversity. Their further studies have been needed for education and awareness.

作者： Shuhana Sultana farzana Saleh Liaquat Ali Department of Health Promotion & Health Education Bangladesh University of Health Sciences (BUHS) Dhaka Bangladesh Department of Community Nutrition Bangladesh University of Health Sciences (BUHS) Dhaka Bangladesh Department of Biochemistry & Cell Biology Bangladesh University of Health Sciences (BUHS) Dhaka Bangladesh

Background: No published information is available on the status of childhood obesity in Bangladeshi primary school children of urban middle and upper-middle income group. The aim of the study was to explore the proportion of childhood obesity in the primary school children of middle and upper-middle income group in capital city and to gather information on their dietary pattern and physical activity. Methods: One hundred and fifty children (age 9 ± 1 years, height (ht) 118 ± 20 cm, weight (wt) 36 ± 8 kg, wt/ht% 126 ± 24, mean ± SD) were selected purposively from the primary schools of Dhaka city. On the basis of predefined scoring, subjects were classified as underweight, normal, overweight and obese if their weight-for-height values were 120% of median values for Bangladeshi children respectively. Dietary intake and energy expenditure of the study subjects were calculated by standard techniques. Results: The proportion of childhood overweight and obesity was 52% and 20%. The proportion of overweight and obesity was higher (78%) among girls compared to boys (54%). Similarly, height, weight and other anthropometrics indices were significantly (p < 0.05) higher in girls compared to boys. The daily intake of carbohydrate and protein was significantly (p < 0.05) higher among obese group. Total energy balance was significantly correlated with weight-for-height% (r = 0.541, p = 0.0001). Conclusions: A higher proportion of overweight and obesity had been found in girls’ children than their counter parts in this study. Positive energy balance with higher energy intake from carbohydrate and fast/processed food culture habit were found among primary school children of middle and upper-middle income group in the capital city of Bangladesh.

Advances in Microbiology 2015年第5期5卷 291-297页

作者： farzana Diba Fahmida Alam Ali Azam Talukder Department of Microbiology Jahangirnagar University Dhaka Bangladesh Human Genome Centre School of Medical Sciences Universiti Sains Malaysia Kubang Kerian Malaysia

Acetic acid bacteria capable of growing at 30°C - 37°C were collected from various decomposed fruits available in Bangladeshi local markets in order to assess their suitability for vinegar production. Initially, 42 microorganisms were isolated from decomposed fruits like grapes, mangoes, pineapples, oranges, safeda etc. during summer when temperature reaches up to 37°C. Then their growths were checked in YPG medium containing various ethanol concentrations at different time point at 37°C. From the preliminary screening, 15 Gram negative bacterial isolates have produced halos or yellow zone around the colonies on YPG agar plate at 37°C which indicated acetic acid production capability by those bacteria. Furthermore, acetic acid production rates were determined by titration method and about 3 - 6.9 gm/100ml acetic acid were estimated by using 4% ethanol at 37°C by shaking culture for 3 days. Several biochemical analysis revealed that our collection contained huge amount of acetic acid producing bacteria and some of them could be potential candidates for vinegar production.

Molecular dynamics （MD） computer simulation techniques, as a powerful tool commonly utilized by the liquid crystal display （LCD） community, usually are employed for computing the equilibrium and transport properties of a classical many body system, since they are very similar to real experiments in many respects. In this paper we pre- sent molecular dynamics computer simulation results taken for a mixture of the two different kinds of nematic liq- uid crystals （LCs）. We calculated rotational viscosity from Brownian behavior with friction of the mean director of the mixture comprising pentylcyanobiphenol （5CB） and decylcyanobiphenol （10CB） by using molecular dynamics computer simulation, where intermolecular potential parameter is Generalized AMBER force field （GAFF）. Our computed results show a good agreement with the experimental results.

作者： farzana Khan（范佳娜）东华大学

学位级别：硕士

Current study investigated the mechanical property of Sheet Moulding Compound (SMC) using25mm-long glass fiber as reinforcement for the possibility of producing bathtub materials. In this experiment SMC cuttings from the bathtub immersed into hot water (90℃) from250-1500hrs followed by tensile test with Acoustic Emission (AE) monitoring and microscopic investigation to evaluate its initial fracture and degradation mechanism. The specimens were prepared in two perpendicular directions determined as Y (resin flowing direction) and X direction in the paper. The initial fracture generated in tensile test was determined by both tensile stress-strain curve and AE measurement (140kHz and1MHz resonant frequencies).The result shows that different fiber orientation and mechanical property between Y and X are occurred due to the fiber flowing during molding. In most cases Y specimen tensile strength and modulus is higher than X specimen. Initial fracture stress from stress-strain curve and AE measurement were obtained and was proposed as an allowable products design.

Application of Traffic Calming Devices in Developing Countries: Learning Lesson from Bangladesh

引用

Journal of Transportation Technologies 2018年第2期8卷 119-135页

作者： farzana Rahman Tri Basuki Joewono Shahidullah Al Masum Department of Civil Engineering University of Asia Pacific Dhaka Bangladesh Parahyangan Catholic University Bandung Indonesia Military Institute of Science and Technology Dhaka Bangladesh

Traffic calming devices become more favorable for many cities to manage traffic in urban as well as neighborhood areas. Many developing cities already initiated the implementation, while the process has a wide variation in both quality and quantity. The objective of this study is to evaluate the justification of speed humps in urban roads and also to recommend a guideline for installation of speed humps as a traffic calming device in Dhaka city, Bangladesh. It was found that there are vast variations in the implementation, while general public also express an immense disparity of perception about devices quality and suitability and their agreement. Lesson learned from Dhaka City shows that selecting an appropriate placement and dimension of the traffic humps is an urgent requirement to be solved by government by providing standards, guidelines, and policy when there is an initiative to implement or improve traffic calming application.
