Published: October 2020

Introduction: Autism spectrum disorder (ASD) is prevalent globally. Fundamental impairment of communication and social interactions are common features of ASD children. Parents of autistic children experience parenting differently with severe physical and psychological problems involved and suffer from higher parenting stress which ultimately influence their quality of life. Empowering parents of children with autism for use of available social support, to get assistance of coping strategies and to promote self confidence of odd feelings are essential for enabling the parents to improve their quality of life by reducing theirstress.
Objectives: To assess the link of parenting stress and coping capacity with quality of life among the parents whose children suffer from autism spectrum disorder (ASD) and to help the government and relevant organizations take the required steps to improve the living conditions of the parents of children having ASD.
Materials and Methods: This cross-sectional study was executed from July 2016 to June 2017 among 175 parents whose children have autism spectrum disorder. Data were collected by in-person interview method with systematic random sampling followed by semi-structured questionnaire.
Results: Majority (48.6%) of the parents were between 31 to 40 years of age and mean (±SD) age of the parents was 37.75 ±8.04 with the range of 21-64 years. Most (53.7%) of the parents were female. Majority of the parents (42.9%) were educated up to graduation level and (72.0%) were service holders. Most (93.1%) parents were from urban areas and (92.6%) parents were represents from nuclear family. Majority parents (55.4%) had 2 children and most (70.9%) children have noticed their first symptom at the age of 2 and maximum (47.4%) children were identified with ASD at three years of age. Maximum (62.9%) family had monthly income of Tk. 20001-50000 and majority children (77.1%) were diagnosed in different government hospitals.
Conclusion: Considering the fact that ASD is a mushrooming public health problem in Bangladesh, widespread prior diagnostic facilities are needed to be made available all over the country especially in peri-urban and urban areas, to measure the parenting stress and identify ways of coping capacity for improving lives of parents whose children have ASD.

On the heat waves in Bangladesh, their trends and associated large scale tropospheric conditions
Authors: Karmakar Samarendra , Das Mohan Kumar 
Published: October 2020

Attempts have been made to study the heat waves along with the trends in Bangladesh and the large-scale tropospheric conditions over Bangladesh and neighbourhood responsible for generating heat waves in the country. Maximum temperature (Tmax) for the period 1981-2016 has been used in the study. Based on the definition of heat waves of Bangladesh Meteorological Department (BMD), the frequencies of days with Tmax≥360C and ≥ 380C have been computed and their trends are investigated to delineate the areas of heat waves in Bangladesh. During the period 1981-2016, Tmax≥360C is found to prevail annually for 79 days at Rajshahi, 51 days at Mongla, 50 days at Khulna in 2014 whereas it is found to prevail annually for 85 days at Chuadanga in 1992, 78 days at Jessore in 2010, 72 days at Satkhira in 1986 and 68 days at Ishurdi in 1995. In 2014, Tmax≥360C is found to exist annually for many days in western pat of Bangladesh in comparison to the eastern and costal region of the country. That is why year 2014 has been selected to study waves extensively. The study reveals that the monthly, seasonal and annual frequency of Tmax≥360C have increasing trends in Bangladesh except a very few places, having the highest increasing trends over southwestern part of the country with increasing rates of 0.816 day/year and 1.02 day/year, respectively at Mongla. The highest increasing trends over southwestern part may be due to the advection and penetration of higher Tmax due to northwesterly winds and less rainfall over the area. The seasonal and annual frequencies of Tmax≥380C have increasing trends at less than 50% stations in Bangladesh; some of the increasing trends of the seasonal and annual frequency of maximum temperature ≥380C are statistically significant up to 95-99% level of significance. The large-scale synoptic conditions show that heat waves are found to enter Bangladesh from the west/northwest due to the advection of higher Tmax from the west. Heat waves extend from west to east up to about central Bangladesh and a separate area of heat waves develop over the Chittagong Hill Tracts, the reason of which may be due to the diverging pattern of wind flows near the Chittagong Hill Tracts in the year of heat waves. Heat waves are absent along Sandwip-M.Court-Feni-Comilla region. In 2014, heat waves are found to be due to the influence of sub-tropical high over India and its extension over Bangladesh at the surface and at 850 hPa level with strong westerly/northwesterly winds at 850 hPa, influence of anticyclones persisting for many days over the Bay of Bengal at 300 hPa level, absence of upper level westerly troughs over India and Bangladesh

Authors: Mamun Md Abdullah Al , Hossain Mohammad Mamun , Khan Mubarak Ahmad 
Published: October 2020

Polyester fabric is usually dyed with disperse dyes which has severe limitations specially toxicity and environmental issues. The aim of the present research is to introduce an ecofriendly dyeing process for polyester fabric with natural dyes. The natural colorants were extracted from mahogany seed pods using the simple acid boiling method. The spectroscopic analysis of the crude extract was carried out by UV and IR spectra of the extracted dyes and illuminated the presence of natural tannins as coloring materials in the crude extract. 10g fabric was dyed in 200cc extracted solution at 130⁰C for 60 minutes in exhaust dyeing method followed by neutralization and soaping. Finally, a light brown dyed fabric was obtained. The dyed fabric exhibited color strength in terms of k/s value of 0.63 (λmax 360nm), lightness of 80.565 and chromaticity value of 12.002 CIE units. Different samples were dyed by fluctuating the dyeing period. The dyeing traits of the dyed materials were judged in terms of their color strength and fatness properties. All testes were carried out following the ISO standards. From the results, it is lucid that the dyed fabric showed acceptable color fastness properties in case of all fastness except color fastness to light. It is observed that dyeing time had profound influence on the color strength (k/s value) of the dyed material. The k/s value increases with the increase of dyeing period up to 120 minutes. The maximum color strength (0.76) was noted for the fabric. The shorter dyeing time produces lighter samples and the longer dyeing time produced colorful samples.

Forecasting the Average Temperature Rise in Bangladesh: A Time Series Analysis
Authors: Paul Sneha , Roy Shuvendu 
Published: October 2020

Global warming has caused a significant increment in surface temperature around the world, including Bangladesh. In this study, the temperature data of Bangladesh over the past 100 years has been analyzed to see the temperature increment pattern. It has been seen that the average temperature has risen by 10C over the last century. Using daily average temperature data of Bangladesh, machine learning-based time series forecasting model has been developed to predict the future temperature of Bangladesh. The model can predict the minimum, maximum, and average temperatures of any year in the future. This has been treated as a regression problem and Linear, Polynomial, and Support Vector Regression have been proposed to build the prediction model. The proposed model has a mean square error of 0.00470C which is a good margin for such a model. Using the model, the average temperature of Bangladesh is predicted over the next hundred years.

Influence of Annealing Temperature on the Crystallization Kinetics of Fe82Si8B10 Amorphous Ribbon
Authors: Sikder A Said , Nath SD , Sikder SS 
Published: October 2020

Amorphous soft magnetic materials have significant potential applications in specialist power transformers and in inductive devices. With the composition of Fe82Si8B10, 82% of the transition metals Fe and about 18% of metalloid or glass-former elements like B and Si are strongly magnetic at room temperature and offer dynamic opportunities for engineering applications. The crystallization kinetics has been studied by differential thermal analysis (DTA). The sample was annealed in a controlled way in the temperature range of 350-450°C at constant annealing time one hour. The kinetics of primary crystallization α-Fe(Si) phase and secondary crystallization Fe2B phase was studied as affected due to temperature. The sample annealed at 350oC temperature is almost unchanged which is still lower than that of primary crystallization temperature but the same condition when sample annealed at 450°C completely shows that the primary crystallization α-Fe(Si) phase has vanished and crystallization event took place to a good extent.

An Experimental Investigation of Relationship between surface Hardness and Strength of Locally produced TMT 500W bar in Bangladesh
Authors: Ahmad Sazzad , Sajal Wahidur Rahman 
Published: October 2020

The high-strength mild steel bars (usually low carbon steel) are widely used for structural purposes throughout the world including Bangladesh. The strength of these deformed barsis measured through a sample decimation process via Universal Testing Machine (UTM), after which the broken pieces are discarded as scrap for recycling. Therefore, measuring the hardness of steel could be a good indication of strength and will involve less sample and short time for testing. The strength–hardness relationship for steel and cast iron is well defined. However, the TMT 500W deformed bar using in Bangladesh has different structural phenomena due to its unique fabrication technique. Therefore, it is necessary to understand how the strength varies with hardness for this grade of steel. The current research aims to explore the hardness–strength relationship for TMT (Thermomechanical Treatment) 500W bar as an alternate of the tensile test to minimize the wastage, cost and time of testing. Several TMT 500W bars were collected from the local market and measured the Rockwell Hardness B (HRB), strength and other relevant macroscopic/microscopic parameters. Finally, two empirical relationships of yield and tensile strength have been established using rim hardness, core hardness, and rim thickness data. The actual strength data shows a good agreement with present findings and the result variation is found less than 2% and 3% in the case of yield strength and tensile strength respectively.

La socialización patrimonial a través de la recreación histórica y la arqueología experimental
Authors: Ruiz García David 
Published: October 2020

El modelo tradicional de museo local se encuentra obsoleto y abocado al fracaso, y necesariamente obligado a adaptarse a las nuevas necesidades de una ciudadanía cada vez más exigente y heterogénea, que solicita nuevos servicios y actividades cada vez más dinámicas. Su tradicional función como mero espacio de exposición de objetos no funciona, convirtiéndose en un tipo de institución cultural cuya mera existencia está siendo continuamente cuestionada.
Necesita reforzarse, hacer entender al conjunto de la sociedad que es necesaria y que es espacio de memoria colectiva fundamental para un progreso equilibrado. Para conseguir dichos objetivos se necesita trabajar con la población más cercana, implicándola no como una simple observadora; haciéndola partícipe de forma activa y lineal en cada uno de sus programas. Es necesario trabajar con la socialización patrimonial y en Colección Museográfica de Gilena tenemos la respuesta y una trayectoria de éxito que respalda nuestro enfoque.

Authors: Miralles Benito Alfredo 
Published: October 2020

Arquitecturas de la Memoria es una app de geolocalización para crear una cartografía interactiva de recuerdos de la comunidad, vinculados al espacio público como vertebrador de la vida en común, con el objetivo de favorecer el diálogo intergeneracional.
Este proyecto propone un proceso de encuentro con los mayores de una comunidad y pone en valor la memoria colectiva como fuente de patrimonio inmaterial del territorio. Trata de generar un proceso de mediación y de acercamiento de estos contenidos a los más jóvenes a través de la tecnología.
La esencia del proyecto es el encuentro con la comunidad para generar un proceso de carácter participativo con la ciudadanía. A través de entrevistas y dinámicas artísticas se crea un relato colectivo en primera persona, y se explora la identidad de un territorio en base a los recuerdos de sus vecinos. La tecnología aparece al final del proceso para captar el interés de los más jóvenes y facilitar el diálogo intergeneracional en un momento en el que ya no nos sentamos a escuchar las historias de nuestros mayores; en el que se han roto los lazos de oralidad frente al dominio de la imagen y las pantallas. Este proyecto crea un espacio para contarnos las historias de nuestras vidas, y regenerar ese lazo intergeneracional, tejiendo afectos que la vida contemporánea a veces nos hace creer olvidados. Arquitecturas de la memoria permite a los usuarios de la app recorrer las calles acompañados de las voces de sus habitantes.
