It is significant to find a more rigorous and satisfactory proof of the crystallographic restriction theorem. The inexistence of C5 axis of symmetry is equivalent of that pentagons are impossible to fill all the space with a connected array of pentagons, on the basis of this viewpoint, using a purely mathematical approach the paper rigorously proves that C5 and Cn (n ≥7 ) axes of symmetry cannot exist , and one –, two –, three –, four – and six – fold axes of rotational symmetry are allowable. Therefore, the axes of symmetry of the crystal can merely exist C1, C2, C3, C4 and C6 .

Published: December 2018

Background : Diabetes mellitus is one of the important risk factors for coronary artery disease. The hemoglobin A1c is used for evaluating glycemic control in diabetic patients. Here, we conducted the study to evaluate the relationship between HbA1c level and severity of coronary artery disease among the hospitalized patients with ACS.

Materials & Methods : This cross sectional study was conducted in the department of Cardiology, Ibrahim Cardiac Hospital & Research Institute, Dhaka, Bangladesh from September 2015 to December 2015. Total of one hundred patients were studied and they were grouped on the basis of their glycaemic status. One hundred patients with acute coronary syndrome were enrolled in this study. Out of them fifty were diabetic (HbA1c>6.5%) and rest of were nondiabetics (HbA1c<6.5%) ( group-A and B).

Results: Out of one hundred patients fifty eight were male and fourty two were female. Mean age of patients in group-A was 58.54±10.22 years and mean age of patients in group-B was 54.52±13.69 years. Mean age of male and female was 57.72±11.48 years and 54.0±13.08 years respectively. Mean HbA1c of patients in group-A was 11.43±1.43% and group-B was 6.34±0.915%. 38% of group-A and 22% of group-B had triple vessel disease, 26% of group-A and 20% of group- B had double vessel disease and 28% of group-A and 18% of group-B had single vessel disease, and 8% of group-A and 40% of group-B had normal coronary arteries. 48% patients of age group 46-50 in group-A had more incidence in coronary artery disease than other age group which was statistically significant ( p=0.035). 61-75 years age group in group-B patients had coronary artery disease than other age groups which was statistically not significant(p=0.084). Patients of group-A was significantly relation with coronary artery disease (p>.001) and six times greater coronary artery disease than patients of group-B (OR= 6.15, 95% CI for OR =2.074 -18.289).

Conclusions: In this way the importance of appropriate glycaemic control has been emphasized in diabetic patients. This study showed the relation between HbA1c levels and the severity of CAD in patient with type-II diabetes mellitus .Our findings demonstrate that elevated HbA1c level was risk factor for severity of coronary artery disease in ACS patients.

Published: December 2018

Background: Acute myocardial infarction (AMI) is one of the leading causes of death and disability all over the world. Primary percutaneous coronary intervention (PCI) is the treatment of choice for patients with acute ST segment elevation myocardial infarction (STEMI). Primary PCI is being increasingly done in our country also. But the factor influencing the outcome of primary PCI in our setting are mostly unknown. The present study was conducted to investigate factors that influencing the short term outcomes of primary PCI.

Materials and methods: This prospective observational study was conducted from September 2014 to January 2016in the Department of Cardiology, National Institute of Cardiovascular Diseases (NICVD), Dhaka. 48 patients were selected by purposive sampling. Patients with acute STEMI treated with primary PCI were included in the study based on inclusion and exclusion criteria. Effect of factors including advanced age, male sex, diabetes mellitus, hypertension, dyslipidemia, serum creatinine, left ventricular ejection fraction, anterior myocardial infarction (MI), thrombolysis in myocardial infarction (TIMI) flow, multi vessel disease, angiographic severity score (Leaman score), thrombus aspiration, door to balloon time and total ischemic time on major adverse cardiac events (MACE) i.e. death, post procedural MI, target vessel revascularization (TVR), stroke as well as, on other adverse events like heart failure, cardiogenic shock, major bleeding, significant arrhythmia and stent thrombosis were studied.

Results: The overall incidence of MACE was 2.1%, major bleeding 2.1%, heart failure 4.2% and cardiogenic shock 2.1%. In multivariate analysis, the factors independently influencing the adverse short term outcomes (MACE and other adverse events) were diabetes mellitus (odds ratio (OR) 2.55, 95% confidence interval (CI) 1.180 to 4.124, p=0.02), anterior MI (OR 1.48, 95% CI 1.020 to 1.926, p=0.04), total ischaemic time (OR 1.49, 95% CI 1.044 to 2.444, p=0.04), multivessel coronary artery disease (OR 1.77, 95% CI 1.26 to 3.261, p=0.03) and Leaman score (OR 2.5, 95% CI 1.100-4.504, p=.03).

Conclusion: According to our finding, diabetes mellitus, anterior myocardial infarction, total ischemic time, multivessel coronary artery disease and high Leaman score are predictors of adverse short term outcomes of primary PCI

Authors: Muhtarima Jannat , Tumpa Farzana Haque , Islam Md. Rashidul , Khokon Md. Atiqur Rahman
Published: December 2018

Twelve isolates of Colletotrichum capsici and Colletotrichum gloeosporides were isolated from anthracnose infected chilli fruits from different areas of Mymensingh. Isolated pure fungal isolates were grouped on the basis of their morphological characters viz. colony color and compactness, size, shape and number of conidia. The white colored isolates were identified as C. capsici and showed faster growth on PDA medium. In contrast, grey colored fungal isolates were identified as C. gloeosporides and comparatively slow growth on PDA medium. All the fungal isolates were pathogenically active and developed typical symptoms on both green and ripe fruits of chilli. The isolates of C. capsici collected from Kalibari showed the highest infection (74.99%) on fruit surface followed by Muktijoddhar bazar (61.83%). Differential tolerance was observed as fungal growth was different against 0.05% and 0.1% carbendazim while 0.2% carbendazim was lethal against all fungal isolates. The results indicate that severity of anthracnose of chilli is different may be due to aggressiveness of fungal and their tolerance against common fungicide like carbendazim.

Authors: Islam Fatema , Salam Md. Abdus , Kader Md. Abdul
Published: December 2018

Weed management in a sustainable way is the ultimate target of Agronomists to maximize crop yield per unit area. To develop a sustainable weed management technique, an experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to study the effect of different weed management techniques on the performance of wheat cultivars. The experiment comprised three wheat cultivars; viz. BARI Gom-28, BARI Gom-29 and BARI Gom-30 and five weed management techniques namely, no weeding (W0), two hand weedings (HW) at 20 DAS and 40 DAS (W1), use of rice straw mulch @ 6 t ha–1 (W2), use of pre emergence herbicide Panida @ 1 L ha–1 (W3) and use of pre emergence herbicide + one hand weeding (HW) at 40 DAS (W4). The experiment was laid out in a split-plot design with three replications. The experimental plots were infested by different weed species.  Annual weeds were outnumbered than perennial and constitute 84.74% against 15.26%, respectively. Among them, the five most dominant weed species based on the importance value in descending order were Polygonum orientale>Chenopodium album >Cynodon dactylon>Sonchus arvensis>Cyperus rotundus and rest of the weed species represent 8.94%. Wheat cultivar BARI Gom-29 produced the highest grain yield (3.44 t ha–1). The highest grain yield (3.29 t ha-1) was obtained from the application of pre emergence herbicide Panida @ 1 L ha–1. But in case of interaction BARI Gom-29 in combination with use of rice straw mulch @ 6 t ha-1 produced the highest grain yield (4.36 t ha–1). The highest grain yield obtained due to highest number of total and effective tillers hill-1 and highest number of grains spike-1 in BARI Gom-29 with application of rice straw mulch @ 6 t ha–1. From the results of the study it may be concluded that BARI Gom-29 with application of rice straw mulch @ 6 t ha–1 technique appears to be the promising technology in controlling weeds as well as obtaining higher grain yield of wheat.

Authors: Chowdhury Tanzin , Rahman Md Arifur , Nahar Kamrun , Chowdhury Md. Akhter Hossain , Khan Md. Sirajul Islam
Published: December 2018

Plant requires suitable soil for higher yield, quality growth and desired crop productivity that differ with soil characteristics, availability of the nutrient elements and overall soil fertility. Aloe vera, a documented medicative plant, is used for numerous medical and cosmetic applications since very beginning of the civilization. An experiment was conducted in Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh to find out the most appropriate soil for A. vera cultivation. Seven types of soils viz., acid, calcareous, non-calcareous, charland, saline, peat and acid sulphate were collected from different locations of Bangladesh. Eighteenth month old Aloe vera seedlings were collected from Shomvogonj, Mymensingh and planted during last week of May, 2017 following completely randomized design (CRD) with three replications. Most of the soils were light grey in colour, acidic to neutral in nature and clay to clay loam in texture except non-calcareous and charland soils. Bulk density, particle density and field capacity ranged from 1.23−1.45 g cm−3, 2.20−2.58 g cm−3 and 27.07−30.20%, respectively. The ranges of pH, EC and organic matter contents were 3.8 to 7.8, 0.25 to 14.04 dS m−1 and 0.88 to 16.40%, respectively. The organic matter content was found as low to moderate except peat soil. Total N, exchangeable K, available P and S contents ranged from 0.05−0.95%, 0.17−0.73 cmol kg−1, 3.09−12.10 and 11.06−735.12 µg g−1 soil, respectively. Growth and leaf biomass yield of A. vera was significantly influenced by different soil types. The highest plant height, leaf number, leaf area and leaf fresh weight were recorded from the plant grown in non-calcareous soil whereas maximum fresh gel weight, dry leaf weight and yield increase over acid sulphate soil were found from the plant grown in calcareous soil. The highest fresh leaf gel weight (907 g plant−1) was obtained from the plant grown in calcareous soil which was identical with the gel weight (880 g plant−1) of the plant grown in acid soil. The yield increase of acid, non-calcareous, charland, saline1 (6.32 dS m−1) and saline2 (8.14 dS m−1) soils over acid sulphate soil were 718, 712, 394, 144 and 86%, respectively. The overall performance of the soils in relation to leaf biomass yield was of the following order: calcareous ≥ acid ≥ non-calcareous > charland > saline1 (6.32 dS m−1) > saline2 (8.14 dS m−1) > peat > acid sulphate soil. The results suggest that farmers could be advised to grow A. vera either in calcareous or acid soils of Bangladesh. Since calcareous and non-calcareous soils are mostly used for growing cereals, pulses, cash crop like sugarcane, fruits etc., acid soil could be used for cultivating this important medicinal crop considering the socio-economic conditions of the country.

Multinomial logistic regression and multivariate logistic regression have been used to find out the determinants and impact of asthma.The result suggests that the likelihood of being in severe asthma is 5.182 times higher if the public rule of smoking is not maintained in work place. Positive impact of access to sunlight and presence of cockroaches, mice or rats in household on reducing asthmatic condition was also revealed in the analyses. The multivariate logistic regression suggests that hypertension and weight change both are significantly influenced by disease status of asthma.This research identifies that along with other determinants smoking in the working places is an important determinant of asthma in Mymensingh zone of Bangladesh. Furthermore, asthma is found to have significant influence on hypertension and weight change which will guide the policy planners and health professionals to address the issues together in systematic fashion. Mymensingh zone being an asthmatic region needs special attention in the national health program.

Published: December 2018

The inverse relationship between farm size and productivity is one of the most debated findings in agricultural productivity researches of developing countries. Aquaculture industries of Bangladesh have been expanded tremendously but most of the aquaculture farms are small and their productivity is not as high as expected. This paper has explored the relationships among farm size, productivity and efficiency of pangas fish farms. A survey was conducted on 125 farmers by direct interviewing in Mymensingh district of Bangladesh.  Stochastic frontier production function was carried out to estimates the level of technical efficiency and polynomial regression was employed to show the relationship among farm size productivity and efficiency in pangas fish farming. In general, pangas fish farming was found to be profitable, where the large size farms were more profitable than the small. Feed and salt had highly significant and positive effects on productivity, while human labor had negative influences. Larger farms were found to be more productive and technically efficient than the smaller one, and the more productive farms were found to be more efficient. These findings could be justifiable by the fact that the large size farms enjoy more financial opportunities, management and marketing facilities in commercial mode and all these facilities help them to enhance productivity and efficiency.

Published: December 2018

The present study was conducted to assess the harvesting procedures, nutritional value of stingray in the coastal district Cox’s Bazar, Bangladesh and its utilization as value-added product. Data were collected through direct observation, focus group discussion, questionnaire interview and cross check interview. It was found that stingray was mainly caught by artisanal fishery using gill net, set bag net and long line within 5-40 m depth ranges about 100-200 km at west direction, 10-60 km at south direction and 50-100 m depth ranges about 60-100 km at southwest direction from Fishery ghat, Cox’s Bazar. In the west direction, stingray harvesting grounds were Sonar char, Rupar char, Char Gongmoti and Dublar char in Patuakhali district, and Cox’s Bazar coast, Teknaf coast, St. Martin’s island coast and the south patches at south direction and middle ground at southwest direction. Generally stingrays was harvested throughout the year but were abundant during December and January. At fish landing center, the supply chain of stingray from fishermen to consumers passed through a number of intermediaries e.g., dealer, wholesaler, retailer and supplier. The market value of stingray varied where fishermen sold at 90-140 Tk/kg that passed through these channels and at last consumers got it at 140-250 Tk/kg. Six species of stingray were found in Fishery ghat, Cox’s Bazar namely Himantura gerrardi, Dasyatis bennetti, Himantura uarnak, Himantura undulata, Himantura bleekeri and Neotrygon kuhlii. Among them H. gerrardi and H. bleekeri were available and very popular in the market. The average moisture, protein, lipid, carbohydrate and ash content of H. bleekeri were determined as 78.08%, 14.80%, 4.31%, 0.95% and 1.87%, respectively and total energy content 103.78 Kcal. Three utilization processes were investigated in this study namely fish ball of stingray, stingray recipe with sour of tomato and stingray recipe with sour of tamarind. Fish ball was preferred as an excellent product and others were as very good products. Dried stingray products were only utilized by tribal peoples. Dried meat, skin and spine were exported abroad namely to China, Thailand, Myanmar and Singapore.

Published: December 2018

Fish pickle was developed from Thai pangus (Pangasianodon  hypophthalamus) fish muscle by using different types of food additives. Mustard oil and soybean oil were used for preparing fish pickle. Dorsal muscle and whole fish muscle without bone were used as raw material for preparing fish pickle. Changes in nutritional composition, pH, bacteriological and sensory attributes were determined at room temperature (30–35°C) according to standard procedures. At room temperature (30-35°C) fish pickle prepared from dorsal muscle and whole fish muscle using both mustard oil and soybean oil remained in acceptable condition until 12/13 days. Bad smell produced in the pickle after 15th day of storage. Moisture, protein, lipid and pH value decreased but ash content increased with the progress of storage period. In case of soybean oil used pickle deterioration was faster than the pickles prepared using mustard oil. Bacterial load was higher in soybean oil pickle and the pickle prepared from whole fish muscle.

Authors: Tabassum Parsa , Khan Shamim Ahmed Kamal Uddin , Siddiqua Mahmuda , Sultana Sabiha
Published: December 2018

Banana is a common and popular subtropical fruit worldwide. Its postharvest life is very short which causes difficulties in marketing and preserving banana at good condition. To find out a better solution of this problem, the current study was conducted during 2017 in the Horticulture Laboratory, Khulna University, Bangladesh, by following the Completely Randomized Design (CRD) of experiment. Harvested banana fruits, sabri (Musa sapientum L) were treated with guava leaf and lemon extracts at different concentrations. Non-treated fruits were considered as control. Both treated and non-treated bananas were stored in covered paper carton at ambient condition. Postharvest performances of the stored fruits during storage were observed for two weeks. After two weeks of storage, lower changes in color (score 6.77), firmness (score 4.43), less TSS content (8.21%), minimum infection (48.89%) and disease severity (score 3.33) and maximum shelf life (8.75 days) were observed in banana fruit with treatment of T3 (guava leaf extract 20% + lemon extract 15%) followed by treatment of T5 (guava leaf extract 40% + lemon extract 15%) treated fruits. However, the T4 treated banana fruit showed maximum vitamin C (1.83 mg/100 g), titratable acidity (0.11%) and reduced sugar (7.13%) after two weeks of storage. In conclusion, combination of guava leaf extract (20% or 40%) + lemon extract (15%) could be suggested for long term storage and maintenance of postharvest qualities at ambient conditions.

Personality-oriented job analysis to identify non-cognitive factors predictive of performance in a doctor of physical therapy program in the United States
Authors: Conard Maureen , Schweizer Kristin
Published: December 2018

This study aimed to conduct a personality-oriented job analysis to identify non-cognitive factors that may predict successful performance or performance difficulties in doctor of physical therapy (DPT) students. The study employed focus groups and a survey with 9 DPT subject matter experts. The focus group participants, who included 3 DPT faculty members and 4 recent graduates of the DPT program, identified 22 non-cognitive factors. Fifteen of these factors were thought to be possibly associated with successful performance and 7 factors were thought to be possibly associated with performance difficulties. Administration of a questionnaire employing the combination job analysis method resulted in 12 factors that could be used in selection, and 10 that could be incorporated into training. The present study employed an established job analysis method using subject matter experts to identify a broad array of factors that go beyond what previous studies have examined, and which may predict success or difficulties in a DPT program.

Published: December 2018

This study aimed to compare age-dependent changes in the relative expression of genes encoding myosin heavy chain (MyHC) isoforms and selected lipid metabolism-related genes in the longissimus dorsi muscle of wild pigs (WPs) and domestic pigs (DPs). Muscles sampled from postnatal day one as well as three-week-old and two-year-old animals were used in quantitative polymerase chain reaction (qPCR) assays, histological evaluations of succinate dehydrogenase (SDH) activity, and intra-myofiber lipid (IMFL) assessment. Expression of the MyHC isoforms displayed the most extensive age- and breed-dependent changes within the first three postnatal weeks. The MyHCembry level decreased significantly faster in the WPs than in the DPs. The relative MyHC-I and -IIa expression was significantly higher in the WPs, and MyHC-IIb was substantially higher in the DPs. The differences in MyHC expression corroborated the number of SDH-positive myofibers and IMFLs. Expression of the peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1α), peroxisome proliferator-activated receptor gamma (PPARγ) and lipoprotein lipase (LPL) genes displayed only age-related variations. In summary, the evidence is provided for accelerated postnatal myofiber transformation directed towards oxidative myofibers in WPs. The SDH activity/staining intensity largely reflected the expression of MyHCs, and not genes involved in lipid uptake and utilization.
Observation of the Velocity Variation of an Explosively-Driven Flat Flyer Depending on the Flyer Width
Authors: Lim Seokbin , Baldovi Philipp
Published: December 2018

Lim proposed a theoretical study on the velocity profile of an explosively-driven flat flyer affected by the rarefaction (or release wave) intrusion during the metal’s projection. This work shows somewhat reasonable agreement in a given range. However, this work is limited only in the early stage of detonation (~3 µs), and the larger scaled flyer projection (or extended time duration) behavior is needed for an engineering perspective. As continued work originating from this investigation, the velocity profile of explosively-driven flyers with different widths is studied based on multiple different approaches which include hydrocode simulation, the Gurney model, and Baum’s side loss correction (or effective charge mass approach), followed by a series of field experiments. In this study, the focus is on the observation of the flat flyer velocity (or terminal velocity) variation, depending on the width of the flyers which vary from 12, 25, 50, and 75 mm (or 100 mm). The terminal velocity profile variation, depending on the flyer width, is observed, and a general trend is identified.

Published: December 2018

The propagation of aerodynamic noise from multi-wind turbines is studied. An efficient hybrid method is developed to jointly predict the aerodynamic and aeroacoustics performances of wind turbines, such as blade loading, rotor power, rotor aerodynamic noise sources, and propagation of noise. This numerical method combined the simulations of wind turbine flow, noise source and its propagation which is solved for long propagation path and under complex flow environment. The results from computational fluid dynamics (CFD) calculations not only provide wind turbine power and thrust information, but also provide detailed wake flow. The wake flow is computed with a 2D actuator disc (AD) method that is based on the axisymmetric flow assumption. The relative inflow velocity and angle of attack (AOA) of each blade element form input data to the noise source model. The noise source is also the initial condition for the wave equation that solves long distance noise propagation in frequency domain. Simulations were conducted under different atmospheric conditions which showed that wake flow is an important part that has to be included in wind turbine noise propagation.
Variability and Mechanisms of Megadroughts over Eastern China during the Last Millennium: A Model Study
Authors: Ning Liang , Liu Jian , Wang Bin , Chen Kefan , Yan Mi , Jin Chunhan , Wang Qianru
Published: December 2018

The variability and mechanisms of multi-decadal megadroughts over eastern China during the last millennium were investigated using a control, full-forcing, and four sensitivity experiments from the Community Earth System Model (CESM) Last Millennium Ensemble (LME) archive. The model simulated megadroughts have comparable magnitudes and durations with those derived from reconstructed proxy data, although the megadroughts are not temporally synchronous. In all experiments, the megadroughts exhibit similar spatial structures, corresponding to a weakening of the East Asia summer monsoon (EASM) and a strengthening of the East Asia winter monsoon (EAWM). The results show that internal climate variability within the coupled climate system plays an essential role in triggering megadroughts, while different external forcings may contribute to persistence and modify the anomaly patterns of megadroughts. A pattern of meridional tripolar (warm-cold-warm) sea surface temperature (SST) anomalies in the western Pacific stretching from the equator to high latitude is responsible for the EASM weakening and EAWM strengthening. The weakening of the EASM and strengthening of the EAWM are essentially caused by negative SST anomalies over the northwestern Pacific and positive SST anomalies over the equatorial western Pacific, which are associated with a La Niña-like SST gradient across the tropical Pacific. The external forcings prolong the megadroughts through maintenance of the meridional tripolar SST anomalies and enlarge the megadrought spatial extent by magnifying the meridional tripolar SST anomalies.
