Rajshahi is well-known as a model city for clean air in Bangladesh but in recent time air pollution is increasing in metropolitan areas. This study aims to examine the concentration of Particulate Matters (PM₁, PM₂.₅, and PM₁₀) in the Rajshahi metropolitan area during March 2021, with a focus on distinct land use categories. The research was carried out in 40 different sites within the Rajshahi metropolitan area, utilizing a portable device for measuring air quality. It was found that the average concentrations of PM₂.₅ and PM₁₀ were 56.41 and 72.63 µg/m³ respectively, which is 2.25 and 1.45-fold than World Health Organizations (WHO) Standards. According to this study, the three locations with the highest levels of PM₂.₅ pollution were the Mohanonda project gate (105.750 µg/m³), Textile Mill (79.750 µg/m³), and Sarkar Cold Storage (71.750 µg/m³). The concentration of PM₂.₅ in the most polluted location was found to be 1.63 times than the standard level set by Department of Environment (DoE) and 4.23 times higher than the WHO standard. Furthermore, it was calculated that the average PM₂.₅/PM₁₀ ratio was 77.70% and the average PM₁/PM₂.₅ ratio was 60.16%. It also revealed that temperature is negatively and humidity is positively correlated with PM₁, PM₂.₅ and PM₁₀, which means any change in the concentration of PM₁, PM₂.₅ and PM₁₀ can cause a significant change in the percentage of humidity in the same direction, for humidity the change would be in opposite direction. The concentration of PM₂.₅ in ambient air with respect to land use decreases as follows: industrial area > village area > road intersection area > sensitive area > mixed area > commercial area > residential area.

This study was conducted to investigate the morphology, morphometry and production performances of exotic goat breeds and their crossbreds available at Boalia, Shahmokhdum, Rajpara and Matihar thana under Rajshahi metropolitan city. A total of 73 animals’ information was collected from 39 exotic goat flock owners using a semi-structured questionnaire through interviewing of farmers, visual observation and on-spot measurement of the animals. Exotic goat breeds and their crosses were found predominantly higher (>93%) in Rajshahi Metropolitan areas where less than 7% Black Bengal goats were identified. In most cases, deviation of breed specific coat color due to crossing between different types of crossbreds among the populations was noted. The genotype frequencies of Beetal, Kalahari, Sirohi, Jamunapari, Anglo Nubian and their crossbreds and Black Bengal goats were found to be 50.68, 15.07, 13.70, 8.22, 8.22 and 4.11%, respectively. The average mature live weight (12 to 18 months) of those corresponding exotic genotypes in male and female respectively were found 46.88±5.66, 56.07±8.03, 32.67±8.09, 59.54±7.96 and 64.06±4.67 kg, and 21.70±2.24, 22.41±3.64, 17.37±4.05, 24.5±0.5 and 27.47±6.85 kg. Irrespective of genotypes, the mean age at puberty, lactation length, litter size, kidding interval and days open were found 167.50±3.49 days, 76.61±4.90 days, 1.71±0.10, 224.44±5.56 days and 52.64 ± 2.30 days, respectively. However, none of the aforementioned traits differed significantly (P>0.05) among the five different exotic genotypes. In conclusion, this study provides some basic information on the performances of exotic goat breeds or their crossbreds at Metropolitan areas under intensive management conditions which could be utilized for designing proper breeding plan in their conservation and simultaneous improvement.

Bangladesh is a land scarce country where per capita cultivated land is only 12.5 decimals. It is claimed that every year about one percent of farm land in the country is being converted to non-agricultural uses. The study is based mainly on field survey covering 2 villages (Narikel Baria and Baze Silinda) from 10 sub-urban villages around Rajshahi City Corporation under Paba Upazila of Rajshahi district. The study area was selected purposively and the respondents of this research work were selected randomly. The major focus was on to mention the general land use pattern of the area, estimates the agricultural land conversion besides determining the causes and consequences affecting such conversion. Both Narikel Baria and Baze Silinda villages were selected as study area because of its relatively higher growth in infrastructure. In order to fulfill the goal of this study, primary and secondary data were collected from various sources and to analyze and process of collected data the SPSS, Excel and Arc GIS software were used. Different types of descriptive statistics were applied for representing the analyzed data. It is observed that the land conversion form agriculture to non-agriculture allied in recent time is more than the previous time due to gradually increasing land demand in housing and relevant services which invites adverse impact on agricultural land as well as its dependent population. So, it is necessary to take integrated land-use planning to offer better options for the fulfillment of land demand both of housing and agricultural sectors.

Background: Now a days our country has improved remarkably in all sectors of health care facilities. But still patients compliance is poor. Though the private practitioners claim higher fees, their practice in writing prescription is controversial. Therefore the present study was designed to evaluate the traditional prescriptions done by registered medical practitioners with that of standard prescription models.Methodology: A cross sectional type of descriptive study was conducted to evaluate the prescribing pattern of the different category of private practitioners practicing within Rajshahi Metropolitan area from 1st November, 2014 to 1st April, 2015. The study was conducted by focusing on the practitioners' prescription layout or mechanics of prescription order writing and the prescribing indicator part of the WHO core drug use indicators. After completion of collection, all the data were coded as well as analyzed by SPSS version 17.Results: Data were collected from 300 patients, 3 patients from each practitioner. Within the superscription part, gender and weight of patients were mentioned only in 1% and 12% of the prescriptions, subscription or direction to the pharmacists was not present even in a single prescription. Follow up advices were found only in 30% of prescriptions and registration numbers of the physicians were mentioned only in 15% of the prescriptions. According to the prescribing indicator, the average number of drugs per encounter was 4.38 and 0% drugs were prescribed by generic name. 13.3% of encounters were with an injection prescribed, only 29.05% drugs were prescribed from EDL (Essential Drug List) of Bangladesh.Conclusion: Standard prescription prescribed by the practitioners was not satisfactory. So the private practitioners should be more aware about the writing of prescriptions in a proper way.KYAMC Journal Vol. 7, No.-1, Jul 2016, Page 691-696

The study was conducted to investigate the incidence of gastrointestinal parasites of buffalo in different slaughter houses of Chittagong Metropolitan Area, Bangladesh. A total of 100 faecal samples were collected from three slaughter houses and studied by coproscopic examinations. Direct smear, sedimentation and floatation techniques along with egg micrometry were conducted to identify various parasitic eggs. Among 100 faecal samples 69% were positive for different individual parasitic infestation. Trematodes, nematodes, cestodes and protozoan infestations were 48%, 16%, 2% and 3%, respectively. Among the trematodes Schistosoma sp. (23%), Paramphistomum sp. (15%) and Fasciola sp. (10%) were found. Incidence of nematode infestations were Toxocara sp (4%), Oesophagostomum sp. (5%), Cooperia sp. (2%), Bunostomum sp. (3%) and 1% for both Trihostrongylus sp. and Strongyloides sp. Mixed infection were observed 7% of positive samples. Results indicate that the heavy worm burden in buffaloes causes severe economic loss to the farmers by reducing the overall productivity.DOI: http://dx.doi.org/10.3329/ujzru.v30i0.10703 Univ. j. zool.

Milk contains many nutrients including carbohydrate, protein, fat, vitamins and minerals. Milk protein has high nutritional value because it contains all the essential amino acids. Considering the nutritive value, milk is widely consumed by the people as an ideal food. The biochemical changes in milk and milk products by microorganisms can be either desirable or undesirable. The safety of milk and milk products with respect to food borne diseases is of great concern around the world. Therefore, the present study was undertaken to determine the prevalence of Escherichia coli in milk and milk product with their antibiogram assay. A total of 150 milk and milk product (yogurt) samples were collected from Rajshahi Metropolitan area of Bangladesh and analyzed by cultural, staining and biochemical tests for the isolation and identification of E. coli. Antibiogram assay of all the isolates were done by disk diffusion method. The overall prevalence of E. coli was 20.0% in milk and milk product (yogurt) in Rajshahi Metropolitan area. The prevalence of E. coli was 26.0% and 34.0% in raw milk and in milk product (yogurt), respectively. E. coli was not detected in pasteurized milk in this study. In antibiogram assay, isolated E. coli showed 100.0%, 60.0%, 40.0%, 40.0%, 33.3%, 33.3%, 20.0%, and 10.0% resistance to penicillin, gentamycin, ampicillin, streptomycin, amoxycillin, sulfamethoxasole-trimethoprim, nalidixic acid, and ciprofloxacin, respectively. The isolates also showed 73.3%, 60.0%, 53.3%, 53.3%, 30.0%, 23.3%, and 20% sensitive to ciprofloxacin, nalidixic acid, sulfamethoxasole-trimethoprim, streptomycin, amoxycillin, ampicillin, and gentamycin, respectively. The findings of this experiment speculated that the use of ciprofloxacin and nalidixic acid may have the preference in the clinical control of milk borne E. coli infection in Bangladesh. J.

Context: Physico-chemical factors directly affect the water quality. Biological parameters varied from pond to pond according to the water quality. Objective: To assess the physico-chemical conditions and plankton abundance in the studied ponds. Materials and Methods: The study was carried out for a period of seven months from June, 2008 to December, 2008 in six ponds of Rajshahi Metropolitan area. Surface water samples were collected once a month at 10-11 am in black plastic bottle and analyzed for the estimation of different parameters. Water temperature, transparency, pH, dissolved oxygen (DO), free carbon dioxide (CO2), biological oxygen demand (BOD), nitrite nitrogen (NO2N), nitrite (NO2), toxic ammonia, ammonium ion (NH4+) and total hardness were measured. The density of plankton was also estimated. Results: The mean values of water temperature varied from 28.73 ± 3.98 (Pond 6) to 29.56 ± 4.68°C (Pond 4) and the pH varied from 7.37 ± 0.26 (Pond 6) to 8.57±0.26 (Pond 4). The DO varied 1.66 ± 1.03 (Pond 1) to 4.68 ± 0.36 mg/l (Pond 6) and the mean value of free CO2 varied from 4.29 ± 0.37 (Pond 5) to 50.91 ±19.30 mg/l (Pond 3). The total hardness was 136.79 ± 20.28 (Pond 6) to 183.14 ± 51.17 mg/l (Pond 3) with NO2varied from 0.003 ± 0.002 (Pond 5) to 2.08 ± 0.59 mg/l (Pond 4). The mean total phytoplankton was 28761.43 ± 2912.62 (Pond 2) to 63629.29 ± 20214.44 cells/l (Pond 4) and the mean total zooplankton was 13314.24 ± 3189.70 cells/l (Pond 5) to 18820.00 ± 932.51 cells/l (Pond 4). Conclusion: The deterioration in the physico-chemical quality and plankton population observed in this study is alarming, and periodic monitoring and preventative measures are required to save the aquatic system from eutrophication.
