Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by cognitive impairments in the initial stage, which lead to severe cognitive dysfunction in the later stage. Action observation therapy (AOT) is a multisensory cognitive rehabilitation technique where the patient initially observes the actions and then tries to perform. The study aimed to examine the impact of AOT along with usual physiotherapy interventions to reduce depression, improve cognition and balance of a patient with AD. A 67 years old patient with AD was selected for this study because the patient has been suffering from depression, dementia, and physical dysfunction along with some other health conditions like diabetes and hypertension. Before starting intervention, a baseline assessment was done through the Beck Depression Inventory (BDI) tool, the Mini-Cog Scale, and the Berg Balance Scale (BBS). The patient received 12 sessions of AOT along with usual physiotherapy interventions thrice a week for four weeks, which included 45 minutes of each session. After four weeks of intervention, the patient demonstrated significant improvement in depression, cognition, and balance, whereas the BDI score declined from moderate 21/63 to mild 15/63 level of depression. The Mini-Cog score improved from 2/5 to 4/5, and the BBS score increased from 18/56 to 37/56. It is concluded that AOT along with usual physiotherapy intervention helps to reduce depression, improve cognition and balance of people with AD.

【目的】砂是一种常见的建筑材料,在水利水电工程、交通、海洋和其他土木工程中应用广泛。在不同的工程应用中,砂土经受不同的加载过程和加载速率。因为加载速率效应,砂在相同幅值荷载作用下产生的变形有一定差异。这项研究旨在深入了解不同应变速率三轴剪切条件下砂的应力应变特性。【方法】采用相对密度为0.9的密砂,开展了一系列三轴固结排水剪切试验,在两种不同围压(750 kPa和2000 kPa)下对试样进行固结后,分别采用三种不同的常应变速率(0.00625%/min,0.0625%/min和0.625%/min)进行应变控制排水剪切。根据试验数据,绘制了应力-应变关系发展曲线,分析了应变速率对砂土偏应力和体积应变演化的影响。【结果】结果表明,在本试验采用的恒定应变速率和围压条件下,密砂在轴向应变约为2%时将发生屈服。屈服前,相同轴应变增量对应的土样偏应力增量和体积应变增量对剪切速率比较敏感,特别是体积应变,即加载应变速率较小时获得的土样剪应力较低,但体积应变(收缩)发展量较大。【结论】在屈服前,砂土的模量随着加载速率的增加而增大;但是屈服后,当加载达到大应变(ε1=15%)条件时,应变率对砂土应力变形的影响不明显。另外,在相同围压下,以不同应变率加载的砂样在加载过程中的应力比(q/p)-偏应变关系呈现出一致性。该研究可以提高对砂土力学特性的认识,并为砂土地基上的结构设计和安全评价提供参考。

This research appraises comparative analysis between single diode and double diode model of photovoltaic (PV) solar cells to enhance the conversion efficiency of power engendering PV solar systems. Single diode model is simple and easy to implement, whereas double diode model has better accuracy which acquiesces for more precise forecast of PV systems performance. Exploration is done on the basis of simulation results and MATLAB tool is used to serve this purpose. Simulations are performed by varying distinct model parameters such as solar irradiance, temperature, value of parasitic resistances, ideality factor of diode and number of series and parallel connected solar cells used to assemble PV array. Conspicuous demonstration is executed to analyze effects of these specifications on the efficiency curve and power vs. voltage output characteristics of PV cell for specified models.

The agenda of this paper is to discuss about the significance and a detailed feasibility study of practical implementation of Smart Grid in Bangladesh. Smart grid refers to an electric power system that enhances grid reliability and efficiency by automatically responding to system disturbances. Power crisis is a major problem for a developing country like Bangladesh. Efficient transmission and distribution of electricity with essential energy resources is a fundamental requirement to provide citizens and economies. The paper analyzes the characteristics of Smart Grid and a comparative analysis with conventional grid system. It also discusses about the efficient transmission and distribution process which will integrate power system with renewable energy and information system.

To cope with the demand and supply of electrical load of an interconnected power system of a country, we need to forecast its demand in advance. In this paper, we use a fuzzy system to forecast electrical load on short-term basis. Here, we consider temperature, humidity, seasons of a year and time segments of a day as the parameters, which govern the demand of electrical load. For each of the parameter, we use several membership functions (MFs) and then apply the Mamd.ni rule on MFs and the output is determined by using the centroid method. Finally, the surface plot reveals the real scenario of the load demand. The difference between actual load and the output of the fuzzy system is found as +1.65% to -13.76%. The concept of the paper can be applied in interconnected power system of Bangladesh to reduce power loss, especially when generation is higher than the demand.

The ecological and sustainable product is the demand of the present world. But it was not possible to produce an ecological and sustainable product for all sectors as the world requires now. The synthetic material is used to produce flame retardant materials due to the unavailable sustainable ecological flame-retardant material. But different researchers are trying to produce sustainable ecological flame-retardant material. This research found that the Spinach leaves Juice, banana pseudostem sap (SAP) and eggshell powder have flame retardant properties. Different literature shows that the ash also has flame retardant properties. So researcher suggested developing the composite material from the above materials with cotton fibres. It may be more effective as fire-retardant composite materials.
