The aim of this study was to investigate the spatio-seasonal variations in water quality and suitability Shitalakhya river, an economically important ecologically critical urban river Bangladesh, along with associated influencing factors possible sources pollution. Therefore, surface samples were collected monthly from five sampling sites, fourteen parameters evaluated. results showed that some studied parameters, e.g., temperature, TDS, TA, TH, NO2–, NO3–, exceeded maximum allowable limit,...
This study aims at demonstrating the nexus between teaching and testing. It investigates how tertiary-level teachers perceive practice English language testing in Bangladesh. analyzes variables influencing this putting an emphasis on much align approaches. In mixed-methods research, ninety-one public university, private government college were surveyed five expert interviewed by structured questions. The findings demonstrate that though tertiary level Bangladesh consider instruction...
Abstract In this paper, we performed thermal analysis in three-dimensional (3-D) chip built on silicon-on insulator substrate. Since heat dissipation is one of the most serious issues 3-D electronics, efficient management necessary for reliable and circuit operation. finite element was used to study feasibility use graphene integrated circuits. The simulation results showed that incorporation spreaders lower maximum temperature chip. We calculated equivalent resistance different design...
Abstract Currently, a well-developed combination of irrigation water quality index (IWQIs) and entropy (EWQIs) for surface appraisal in polluted subtropical urban river is very scarce the literature. To close this gap, we developed IWQIs by establishing statistics-based weights variables recommended FAO 29 standard value using National Sanitation Foundation Water Quality Index (NSFWQI) compared with proposed EWQIs based on information Dhaleshwari River, Bangladesh. Fifty samples were...
Abstract L ‐ and D form oligo(lactic acid)s (OLLA ODLA) grafted α‐cellulose (OLLA‐g‐cellulose ODLA‐g‐cellulose) were prepared by the graft polycondensation reaction in C 6 H 5 CH 3 medium at 130°C 380 mm of mercury pressure. Para‐toluene sulphonic acid (5 wt% acid)) was used as a catalyst whereas potassium persulfate (0.01 co‐catalyst reaction. OLLA ODLA with degree polymerization (DP) 6–7 also ring‐opening ‐lactides 140°C for 10 h stannous octoate (C 16 30 O 4 Sn) motivator, , monomer...
In this study, MnO2 as well core@shell type MnO2@Ag material were prepared through the versatile reverse micelle route. FTIR absorption band at 522 cm-1 was ascribed to Mn-O stretching mode, demonstrating presence of a bond inside structure. XRD used determine crystalline structure samples. Peaks 2θ = 12.7°, 18.1°, 28.8°, 37.5°, 42.1°, 49.9°, 56.2°, and 60.3° matched α-MnO2 diffraction peaks nicely. The spherical shape produced compounds observed in FESEM. results histogram show that...
In this study, the micro-emulsion method was used to create manganese-based cathode materials MnO2 and MnO2@SnO2. For use as in rechargeable zinc-ion batteries, SnO2 coated MnO2@SnO2 were synthesized. FT-IR, Powder X-ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive Spectroscopy (EDS), UV-visible characterize as-prepared materials. Electrochemical impedance spectroscopy (EIS), battery charge-discharge (BCD), cyclic voltammetry (CV) techniques...
Abstract Subsurface deformation is a driver for river path selection when rates become comparable to the autogenic mobility rate of rivers. Here we combine geomorphology, soil and sediment facies analyses, geophysical data Late Quaternary sediments central Garo‐Rajmahal Gap in Northwest Bengal link subsurface with surface processes. We show variable sedimentation characteristics, from slow (<0.8 mm/year) Tista megafan at foot Himalaya nondeposition exposed Barind Tract south, enabling...
Simulation of Super Cyclonic Storm (SuCS) Amphan (2020) has been carried out as a case study to analyze the sensitivity Initial Condition (IC) and Horizontal Resolution (HR) on intensity, track, landfall predictions Tropical Cyclones (TCs). The results suggest that IC HR have significant impact TC simulations. Diminishing in simulation comparatively higher severity system. with reduced lead time smaller forecasted Minimum Central Pressure (MCP) distribution reasonably well. In comparison...
As grapevine (Vitis vinifera L.) is rarely produced in Bangladesh because of unavailability improved varieties, so this study was designed to solve problem through evaluating the effects hormonal combination for duration vitro micro propagation from shoot tips and nodal segments. Firstly, surface sterilization process carried out by using HgCl2 (mercuric chlorite) at 0.1% 3 min best result found. During establishment stage, explants were cultured on MS (Murashige Skoog) basal medium...
A numerical investigation of boundary layer mass transfer flow through an inclined plate with the effect chemical reaction and thermal diffusion is presented in this study. The governing partial differential equations (PDE) are transformed to a system dimensionless non-similar coupled PDEs. transformed, conservations (momentum balance equation, energy equation concentration equation) then solved using approach known as explicit finite difference method (EFDM). Basically EFDM introduced for...
This paper presents an assessment of exposure to extremely low power frequency (ELF) magnetic field in general and occupational settings using three-axis Tesla meter. The measurements are performed at the level PF some typical places where public workers subjected fields. In settings, high value current radiates strong that might exceed safe limit creating possible adverse health effects if proper shielding is not made. Radiated from welding machines measured compared with international...
Climate change is a global threat to the world especially for Bangladesh, due its geographical location. The present study was carried out impacts of climate on livelihood fishers at Meghna, Laukhati and Galachipa river in Bangladesh. assessing effects fishersˊ community rivers near Chandpur Patuakhali districts. data were collected by using well-developed questionnaire from selected areas. average temperature recorded as 30.5±0.90°C, 27.1±1.05°C 27.4±0.60°C dissolved oxygen 6.37±1.11 mg/L,...
A series of CoIII–LnIII–CoIII trinuclear complexes [Ln{Co(Hmtimn)3}2](NO3)3 were prepared by following a simple one-pot synthesis method, mixing an unsymmetrical bidentate ligand 2-(2-imidazolinyl)-6-methoxypheol (H2mtimn) with Co(NO3)2·6H2O and LnX3· 6H2O (where Ln = La, Ce, Pr, Nd, Gd or Dy X NO3− Cl−) in methanolic solution the presence triethylamine air. In reaction mixture, this leads to situ formation tris-chelate CoIII metalloligand unit, which can coordinate LnIII ions through...
Background: Chronic neck pain ranks as the fourth most common cause of disability globally. However, treatment for this condition is expensive and lacks substantial proof its efficacy. Objectives: The study aimed to identify effectiveness myofascial release (MFR) on upper trapezius scalene muscles chronic pain. Methods Materials: was a double-blind, randomized controlled trial. A total 40 individuals with persistent were allocated randomly an experimental control group. trial group provided...
Going to gym is generally considered beneficial and we as physicians definitely recommend exercise for every individual due its various benefits on the mind well body. However overdoing anything may have dire consequences this applies working out at well. There been instances where extreme over incompatible atmosphere in an unaccustomed individual, resulted adverse outcomes which include rhabdomyolysis acute kidney injury hence it always advisable a systematic approach exercise.
