  • The Effect of Brain Gym on Global Cognitive Function of Institutionalized Older People
  • Abstract Cognitive function of older adults is influenced by several factors such as age, sex, education, and physical activity so that it can impact the decrease in progressive cognitive function. It is necessary to implement cognitive training in old people’s care to prevent or delay the onset of age-related cognitive decline. Brain gym is a series of simple motion exercises and is an alternative therapy that stimulates the brain. This study aims to evaluate the effect of brain gym as a cognitive training intervention on global cognitive functioning of institutionalized older population. The study is a non-randomized quasi-experimental one using pre-and…

  • Perceived Stress and Coping Styles among the General Population in Saudi Arabia during COVID-19 Pandemic
  • Abstract This article examines the stress levels, coping responses, and influence of adaptive and maladaptive coping styles on stress in Saudi Arabia during the COVID-19 pandemic. An online cross-sectional survey was distributed to the attendees of a pandemic-related awareness webinars. The questionnaire assessed demographic and clinical characteristics, coping strategies (the brief COPE inventory), and stress levels (the Perceived Stress Scale). A multivariate linear regression analysis was conducted to assess the predictors of stress. The highest adaptive and maladaptive coping styles were reported for religion and self-distraction. Certain groups were independently more vulnerable to experience stress, including young- and middle-aged adults, females,…

  • Microenvironment and cell mechanics
  • Abstract Microenvironment contains biophysical and biochemical elements to maintain survival, growth, proliferation, and differentiation of cells. Any change can lead to cell response to the mechanical forces, which can be described by elasticity. It is an indicator of a cell’s state since it plays an important role in many cellular processes. In many cases, cell elasticity is measured by using discontinuous manner, which may not allow elucidating real-time activity of individual live cells in physiological condition or cell response against microenvironmental changes. I argue that measuring cell elasticity using continuously repetitive nanoindentation technique is important that should be considered. As an…

  • Multi-Feature Fusion-Guided Multiscale Bidirectional Attention Networks for Logistics Pallet Segmentation
  • Abstract In the smart logistics industry, unmanned forklifts that intelligently identify logistics pallets can improve work efficiency in warehousing and transportation and are better than traditional manual forklifts driven by humans. Therefore, they play a critical role in smart warehousing, and semantics segmentation is an effective method to realize the intelligent identification of logistics pallets. However, most current recognition algorithms are ineffective due to the diverse types of pallets, their complex shapes, frequent blockades in production environments, and changing lighting conditions. This paper proposes a novel multi-feature fusion-guided multiscale bidirectional attention (MFMBA) neural network for logistics pallet segmentation. To better predict…

  • Sentiment Analysis of Roman Urdu on E-Commerce Reviews Using Machine Learning
  • Abstract Sentiment analysis task has widely been studied for various languages such as English and French. However, Roman Urdu sentiment analysis yet requires more attention from peer-researchers due to the lack of Off-the-Shelf Natural Language Processing (NLP) solutions. The primary objective of this study is to investigate the diverse machine learning methods for the sentiment analysis of Roman Urdu data which is very informal in nature and needs to be lexically normalized. To mitigate this challenge, we propose a fine-tuned Support Vector Machine (SVM) powered by Roman Urdu Stemmer. In our proposed scheme, the corpus data is initially cleaned to remove…

  • Study on the Structural Characteristics and Physical and Mechanical Properties of Phoebe bournei Thinning Wood
  • Abstract The artificial afforestation of precious Phoebe bournei has been carried out in China. During the cultivation process, thinning wood will be produced. The properties of thinning wood might vary greatly with matured wood and require evaluation for better utilization. The objective of the present study aims to determine the wood structure, fiber morphology, and physical and mechanical properties of the Phoebe bournei thinning wood to help us understand the wood properties and improve its utility value. Three 14-year-old Phoebe bournei were cut from Jindong Forestry Farm of Hunan Province, China. The wood structure and fiber morphology were observed and analyzed…

  • Study on the Tangential Tensile Mechanical Properties of Moso Bamboo
  • Abstract In this work, we used tensile tests to analyze the tangential failure forms of raw bamboo and determine a relationship between tangential tensile strength, elastic modulus, position, density, and moisture content. We found that the tangential mechanical properties of the culm wall were mainly dependent on the mechanical properties of the basic structure of the thin wall. Formulas for calculating the tangential tensile strength of moso bamboo and adjusting the moisture content were also determined. The tangential tensile strength and the tangential tensile modulus of elasticity (TTMOE) followed: outer > middle > inner, and diaphragm > bamboo node > culm…

  • Formaldehyde Free Renewable Thermosetting Foam Based on Biomass Tannin with a Lignin Additive
  • Abstract This study presents easily prepared free formaldehyde bio-based foam based on a prepared thermosetting resin comprising tannin–lignin–furfuryl alcohol-glyoxal (TLFG) via mechanical stirring in presence of ether as a foaming agent. The foam was developed through a co-polycondensation reaction of glyoxal and furfuryl alcohol with condensed tannin and lignin, which is a forest-derived product. Investigation using scanning electron microscopy (SEM) showed more closed-cell structure without cracks and collapse in the TLFG foam, with a higher apparent density with respect to tannin–furanic–formaldehyde (TFF) foam. Differential scanning calorimetry (DSC), dynamic thermomechanical analysis (DTMA), and thermogravimetric analysis (TGA) investigations revealed that the curing process…

  • Preparation and Characterization of Sandwich Structured Materials with Interesting Insulation and Fire Resistance
  • Abstract A cellular material in the form of 3-layered sandwich structure material was prepared via sole use of mechanical stirring without any use of a foaming agent, while Tween-80 was employed as a foam stabilizer via a developed in-situ mold casting. The resulting structure displayed a good appearance with no visual defects. The 3-layered composition of the sandwish structure, “nonporous resin layer-porous foam layer-nonporous resin layer”, was examined in terms of the microstructure, density & density distribution, pulverization ratio, mechanical strength, insulation and flame retardant performance. It was indicated from the results that the bonding between the resin layer and foam…

  • Synthesis and Characterization of Hydrogels Based on Potato Starch/Poly(vinyl Alcohol)/N,N′-Methylenebisacrylamide
  • Abstract Several hydrogels were synthesized by free-radical polymerization in an aqueous medium based on potato starch (PS), poly(vinyl alcohol) (PVA), and N,N′-Methylenebisacrylamide (MBAm), being possible to study these hydrogels as a function of the proportion of components incorporated. In this way, the products generated from the synthesis were characterized by swelling and deswelling kinetics, the first swelling being verified with Schott and statistical models, allowing to contrast the proximity between the experimental and theoretical behavior. Additionally, water retention in soil (R%), spectroscopy (FTIR), morphological (SEM), and thermal (TGA and DSC) analysis allowing to know the intrinsic characteristics of the material, increasing…
