Abstract: The study aimed to establish an anthropometric dataset of Bangladeshi male and female university students. Voluntary participants included 400 students aged 17 to 23 from eight divisional areas of ...

Dissimilarity of absorbing internal radiation dose of 99mTc- diethylenetriaminepentacetate among male, female and international committee for radiation protection - 53 recommended data -

Abstract: Background: Radioisotope tomography is a form of medical imaging of the kidneys that uses radiolabelling. The two most common radiolabelled pharmaceutical agents used are Tc99m-MAG3 (MAG3 is also called mercaptoacetyltriglycine) and Tc-99m-DTPA (diethylenetriaminepentacetate). Tc-99m-DTPA is filtered by the glomerulus and used to measure the glomerular filtration rate and is the second most commonly used renal radiopharmaceutical, primarily because it is the least expensive. The main objective of the present study was to obtain the bio-kinetic data of organ activity as well as organ absorbed dose of Tc99m-DTPA for single photon emitters. Methods: We have carried out a method to obtain accurate organ activity with single photon emission computed tomography (SPECT). Tc-99m-DTPA radiopharmaceutical medicine was used as single photon emitters and we have demonstrated effective decay method and conventional method to obtain accurate organ (seven) activity with single photon emission computed SPECT. The observed organ activity is due to the Tc99m-DTPA is obtained and the data is compared among male, female and ICRP (international committee for radiation protection)-53 recommended data as well. Results: The outcome of study revealed that, dose absorbed power of male is greater than female, so in nuclear medicine centre absorbed doses should be estimated separately both for male and female for more proper treatment opportunity. It is also observed that there is no good agreement of absorbed dose values among male, female and ICRP-53 recommended data. Conclusions: Our achieved result is due to the extreme variation in food values and fundamental needed elements are certainly different between Bangladeshi peoples and foreigners. In case of foreigner’s it is almost equal for male and female, whereas for Bangladeshi male and female it is certainly different.

Stable Carbon and Oxygen Isotopic Composition of Mio-Pliocene Bivalve Shells and Calcareous Sediments in Nhila Anticline, Southeast Bengal Basin, Bangladesh

Abstract: Stable carbon ( δ 13 C) and oxygen ( δ 18 O) isotopes of bivalve shells and calcareous sediments of the Mio-Pliocene Nhila Anticline, southeast Bengal Basin, Bangladesh have been investigated to obtain information on paleoclimate and paleoenvironment conditions during deposition. The δ 13 CPDB, δ 18 OPDB and δ 18 OSMOW values in bivalve shell range from -2.81‰ to -1.56‰, -3.57‰ to -2.39‰ and 27.18‰ to 28.40‰ in bivalve shells and -13.90‰ to -1.75‰, -4.71‰ to -2.13‰ and 26.01‰ to 28.66‰ in calcareous sediments, respectively. The δ 13 CPDB values in bivalve shells are comparable to that of calcareous sediments (~ -1.75‰) in the upper section, but δ 13 CPDB values in calcareous sediments are more negative excursion towards lower section (up to -13.90‰). These results signify that salinity gradients could modified the isotope values and/or strong influence of freshwater conditions. The variable δ 18 OPDB values in both bivalve shell and calcareous sediment suggesting diagenetic alteration of carbonates and water temperature effects. The more negative δ 18 OPDB values imply humid paleoclimatic conditions during the Mio-Pliocene sedimentation. Therefore, the δ 18 OPDB values of the Mio-Pliocene sediments of Nhila Anticline are probably controlled by paleotemperature leading to intensification of high rainfall.

Urdu text in natural scene images: a new dataset and preliminary text detection.

Abstract: Text detection in natural scene images for content analysis is an interesting task. The research community has seen some great developments for English/Mandarin text detection. However, Urdu text extraction in natural scene images is a task not well addressed. In this work, firstly, a new dataset is introduced for Urdu text in natural scene images. The dataset comprises of 500 standalone images acquired from real scenes. Secondly, the channel enhanced Maximally Stable Extremal Region (MSER) method is applied to extract Urdu text regions as candidates in an image. Two-stage filtering mechanism is applied to eliminate non-candidate regions. In the first stage, text and noise are classified based on their geometric properties. In the second stage, a support vector machine classifier is trained to discard non-text candidate regions. After this, text candidate regions are linked using centroid-based vertical and horizontal distances. Text lines are further analyzed by a different classifier based on HOG features to remove non-text regions. Extensive experimentation is performed on the locally developed dataset to evaluate the performance. The experimental results show good performance on test set images. The dataset will be made available for research use. To the best of our knowledge, the work is the first of its kind for the Urdu language and would provide a good dataset for free research use and serve as a baseline performance on the task of Urdu text extraction.

Stability Analysis for Yield of Advanced Potato Genotypes for Commercial Cultivation in Bangladesh

Abstract: Five advanced potato genotypes, along with three check varieties were evaluated at six locations in order to find out the stable varieties for commercial cultivation in Bangladesh. Combined analysis exhibited a highly significant variability among the genotypes, locations and GEI. The average tuber yield at 90 days after planting (DAP) of the genotypes ranged from 31.18 t ha-1 in the check BARI Alu-28 to 43.8 t ha-1 in the clone 9.35. The result of AMMI analysis of tuber yield at 90 DAP also showed that the first IPCA1 captured 55.30% of the interaction SS. IPCA2, IPCA3 and IPCA4 explained 29.01, 8.55 and 7.08% of GE interaction SS, respectively. In general, the AMMI2 model contained 99.94% of the treatment SS, while the residual contained 0.06%. In ASV method, the clone 9.125, followed by the check BARI Alu-28 and clone 9.91 were more stable than 9.35. Biplot of IPCA1 and IPCA2 covers 84.3% of GE interaction. Biplot analysis also showed that clone 9.44 and 9.35 and the environment of Gazipur and Jashore had a better result in the GE interaction. Clone 9.44 had specific adaptation with the environment of Gazipur and Jashore, while 9.35 had specific adaptation with Gazipur and Jamalpur. Clone 9.125, 9.91, BARI Alu-28, BARI Alu-8 and clone 9.112 were located toward the center of the biplot and can be considered as stable. Based on the GSI the most desirable genotype for both stability and high tuber yield is the clone 9.125 followed by clones 9.112, 9.91 and 9.35. SAARC J. Agri., 18(1): 73-86 (2020)
