Objectives: Knowledge Discovery methods get more accurate results when the dimensionality of the data is subsided; dimensionality is an important aspect of any data. Several algorithms have been proposed to increase the accuracy, but most of them generate complex models as the size of the data is extremely large. Objective of this paper is to build a simple model to get high accuracy. Method: In order to increase the accuracy of the Knowledge Discovery methods by substituting the dimensionality, we introduce a novel heuristic functionality, Arbitrary Gini Index (ArGI). Findings: We evaluated the performance of ArGI on the real world datasets. The experiment on the ten real world data sets analysis shows 60% data sets are more accurate for ArGI and 40% for Gini Index. Applications: It is expecting that the applications of ArGI will show a better approach in the real world learning tasks.Keywords

Aim: Newcastle disease (ND) is an important viral disease for poultry caused by avian paramyxovirus which can be identified by its nature of agglutination activity with red blood cell (RBC) of different species. The study was aimed to characterize the hemagglutinating (HA) activity of ND virus (NDV) at three different temperatures using RBC of five avian species, six mammalian species, and eight different human blood groups.
Materials and Methods: The study was conducted from January to December 2014 at Chittagong Veterinary and Animal Sciences University. Five avian and six different mammalian species were selected for the study. In each species, two blood samples were collected aseptically. Eight different blood groups (A+, A−, B+, B−, AB+, AB−, O+, and O−) were studied in human. HA test was performed using two virus strains ND lasota and field isolate of very virulent NDV (VVNDV) with mentioned species of RBC at chilling (4°C), incubating (37°C), and room temperature (24°C).
Results: Avian RBC requires less time for agglutination than mammalian RBC. Incubation temperature (37°C) requires lowest time and chilling temperature requires highest time for agglutination of RBC. Duck RBC requires lowest time (17.81 min) while chicken RBC needs highest (57.5 min) time for HA at incubation temperature and at chilling temperature, respectively, against ND lasota virus and with field strain. Goat RBC requires significantly higher time for HA (184.68 min) at chilling temperature than other mammalian species. Human RBC requires almost similar time but O+ and O− blood group do not show any HA activity. Significant variation (p<0.05) found in quail RBC at incubation temperature. In mammalian species, a significant difference (p<0.05) has been observed in goat and horse RBC at chilling; horse and dog RBC at incubation; goat, horse, buffalo, and dog RBC at room temperature. In human, significant variation (p<0.05) has been found in A+, A− and B− blood group in chilling, in B+ blood group at incubation and A+, B+, B−, AB− blood group at room temperature against two virus strains.
Conclusion: ND is considered as an economically significant disease which is highly contagious in nature infecting many avian species. The threat of ND outbreak to poultry industry necessitates effective control measures to reduce the burden in commercial and backyard farming in Bangladesh.

- Seroprevalence of Bovine Viral Diarrhea Virus in Crossbred Dairy Cattle in Bangladesh
Abstract Views :176 |
PDF Views:0
Materials and Methods: The antibody against BVDV in crossbred dairy cattle serum was detected by indirect enzyme-linked immunosorbent assay. The association of different categorical variables in the prevalence of BVDV has been studied. Blood samples were collected and analyzed to know the hematological variations in the study population.
Results: The overall seroprevalence of BVDV in the study area was 51.1% (95% confidence interval [CI], 40.5-61.5). Among different physiological stages of animals, the highest 57.1% (95% CI, 42.2-71.2) prevalence was in case of non-pregnant animals. Aborted cows were found to be significantly (p<0.05) more seropositive 77.8% (95% CI, 52.4-93.6) than the non-aborted cows (77.8%, 95% CI, 52.4-93.6, compared to 44.7%, 95% CI, 33.3-56.6, respectively). Cows having the history of retained placenta were found more positive than without the history of retained placenta (63.2%, 95% CI, 38.4-83.7, compared to 54.7%, 95% CI, 40.4-68.4, respectively). Among the animals of different age groups, BVDV seroprevalence was higher 61.3% (95% CI, 42.2-78.2) in animals of more than 3 years up to 5 years, whereas 32% was in case of 0-1-year-old. Significant variation found in different geographical areas of the study area. Hematological analyses have shown variation between the BVDV positive and negative animals.
Conclusion: Seroprevalence of BVDV found to be high in the study area is also economically important and cause significant damage to the production industry. Therefore, it is necessary to conduct effective control measures to reduce the burden of BVDV.

Population dynamics of rice black beetle Heteronychus lioderes Redtenbacher was studied deploying light trap, pit method and assessment of tiller infestation. The pest was observed to be active from 29th to 42nd standard week (SW) with peak being in 35th SW as shown with light trap catches. The incidence started from 29th SW and reached a peak during 31st SW (3.8 adults in five pits and 48.4% tiller infestation). The weather factors when correlated with incidence revealed significant positive correlation with rainfall, minimum and maximum temperature, whereas it was non-significant positive one with relative humidity.Keywords
