The double burden of malnutrition (DBM) and anaemia is a growing concern in developing countries. Using the cross-sectional Bangladesh Demographic Health Survey, 2011, 5763 mother–child pairs were examined. In households where mother was overweight, 24.5% children stunted, 19.8% underweight, 9.3% wasted, 51.7% anaemic. Significant regional differences found DBM as well drinking water source, while alone more common well-off (based on wealth index) father employed skilled or service...

Food safety knowledge, attitudes, and street food suppliers consumer behaviors of the capital city Dhaka were investigated. A cross-sectional study was conducted using questionnaires based on previous studies. Three main areas addressed in surveys statistical analysis are; 1) data including gender, age, education, income, training, specific elements related to work experience suppliers, 2) knowledge such as awareness consumers concerning pathogenic microbes that cause poisoning, personal...

Kesterite Cu2ZnSnS4 (CZTS), with direct and tunable bandgap, high absorption coefficient, low-cost processing, earth-abundance, non-toxicity, has become a promising absorber material for emerging thin film solar cells. The growth, phase formation, stoichiometry, as well the electrical optical properties of sputtered grown CZTS films, are greatly influenced by annealing temperature pressure. In this work, we use series characterization techniques followed numerical simulations to determine...

This study sought to evaluate the prevalence of dry eye and meibomian gland dysfunction (MGD) associated factors severe symptoms (SDES) among garments worker Gazipur, Bangladesh. We prospectively collected cross-sectional data for 1050 workers a factory (70% response). All participants had an evaluation Ocular Surface Disease Index (OSDI), detailed ophthalmic examination including tear breakup time (TBUT), ocular surface fluorescein staining, Schirmer's I test. MGD grading was based on...

The global spread of SARS-CoV-2 with its diverse signs and symptoms manifested in COVID-19 patients across different age groups geographic locations perplexed the clinicians public health experts. Emerging variants through continuous mutation a limited arsenal treatment made study viral pathogenesis factors associated disease outcomes holistic approach inevitable, among which pre-existing cardiovascular complications were found to be significantly adverse outcome COVID-19. In addition, has...

Fire disaster is at present causing huge economic loss as well tragedy of human death in a frequent manner. PC based wireless monitoring and control fire detection extinguishing system will provide real time protection from to great extent. In this paper, pc cost effective has been designed developed. The able activate alarm generate short message service (SMS) using GSM modem when detected also the by unleashing extinguisher (foam water). It made up two sensors, computer interfacing board,...

Aims: Iodine deficiency is one of the most common micronutrient deficiencies in Bangladesh. To combat iodine disorders, universal salt iodization mandatory The aim our study was to determine content both packaged and open edible table salts sold at retailer level different areas Bangladesh.
 Study Design: an experimental cross-sectional study.
 Place Duration Study: present conducted food analysis laboratory Department Food Technology Nutrition Science, Noakhali Science University...

A study has been made using finite difference time domain (FDTD) method to investigate the performance of silicon (Si) based two-dimensional (2-D) photonic crystal waveguide (PCW) for biochemical sensing. Circular type PCW analyzed by removing a single row holes from 2-D Si (PC) slab. Sensors contained hexagonal lattice with particular geometric configurations trapped different amount biomolecules e.g. DNA. The transmission spectrums sensor cover refractive indices are calculated....

Double burden of malnutrition (DBM) and anaemia is a growing concern in developing countries. 5,763 mother-child pairs were selected from cross-sectional study (Bangladesh Demographic Health Survey, 2011) to examine DBM households. Overweight mothers had stunted (24.5%), underweight (19.8%), wasted (9.3%) anaemic (51.7%) children. Region drinking water positively associated with both (p < 0.001). Father’s occupation wealth index <0.001) only. More policies awareness...

Fish is a rich source of quality protein and fatty acids. Bangladesh's average daily fish consumption 67.8 grams per people. species are also prone to heavy metal contamination from their surrounding environment. The main objective this research was assess the degree risk associated with various in Dhaka, Bangladesh. Three species—Tilapia (Oreochromis mossambicus), Shorputi (Systomus sarana), Mola (Amblypharyngodon mola)—from three local markets Savar Union, Bangladesh, were selected for...

Bangladesh is well known for the abundant range of fish. Though fish consumption and variety are very high in Bangladesh, biodiversity has been alarmingly declining recent years due to a number factors including country's rapid population growth, industrial water pollution, natural disasters, sea intrusion, salinity, overexploitation fisheries, use harmful gear, dewatering waterbodies. Given that 60% Bangladesh's rural poor functionally landless, lack access land agricultural production,...
