Abstract The sulfate groups in agar structure played a good role in the formation of fiber. However, commercially available agar is usually extracted from red algae by alkali treatment to decrease the content of sulfate group for the purpose of high gel strength. In this paper, an alkali-free method of agar extraction from Gracilaria lemaneiformis was proposed for the wet-spinning purpose. This method is environmentally friendly, reduces the extraction steps, saves energy, and reduces the production cost of agar fiber. The improved agar preparation process not only has higher agar yield, but also has higher molecular weight and sulfate group content,… More > Graphic Abstract

Abstract Background: This study aimed to illustrate the prevalence of CHD by screening children in extremely high-altitude areas (over 4000 m to even 5000 m above sea level) and explore an aid model for early diagnosis and treatment for the Tibetan population. Methods: A total of 2242 students from different schools in Ngamring County, Xigaze city, Tibet from September 2019 to September 2020 were selected for screening. The students were examined through the inquiry of their current medical history and family history, cardiac auscultation and a physical examination, in order to screen out the suspected cases of CHD, and then the… More >

Abstract Flow-type landslide is one type of landslide that generally exhibits characteristics of high flow velocities, long jump distances, and poor predictability. Simulation of its propagation process can provide solutions for risk assessment and mitigation design. The smoothed particle hydrodynamics (SPH) method has been successfully applied to the simulation of two-dimensional (2D) and three-dimensional (3D) flow-like landslides. However, the influence of boundary resistance on the whole process of landslide failure is rarely discussed. In this study, a boundary condition considering friction is proposed and integrated into the SPH method, and its accuracy is verified. Moreover, the Navier-Stokes equation combined with the… More > Graphic Abstract

Abstract It has been shown that early experiences of maltreatment can stably influence an individual’s internal and external aggressive behavior in adulthood. And on what mechanisms do this stability arise? From the perspective of personality solidification theory, this study sample of 1951 primary and secondary school students was used to explore the relationship between child maltreatment, Big Five personality and internalized and externalized aggression, as well as the different mechanisms of differentiation of personality components in child maltreatment on two different natures of aggression, using four scales: The Childhood Trauma Questionnaire (CTQ), Revised NEO Personality Inventory (NEO-PI-R), None-suicidal Self-Injury Scale and… More >

Abstract Ferulic acid (FA) and p-coumaric acid (pCA) in bagasse, wheat straw, corn straw, and corncob were extracted by alkaline hydrolysis and characterized by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). It was found that the FA and most of the pCA in gramineous biomass could be dissociated and released after being treated with 1 M NaOH at 100°C for 4 h. The yields of pCA/FA in bagasse, wheat straw, corn straw, and corncob determined by GC-FID are 39.8/11.5, 13.7/11.0, 28.0/11.0, and 35.1/14.5 mg/g, respectively. The raw materials and the treated solid residues were characterized by gel-state 2D Heteronuclear Single… More > Graphic Abstract

Abstract The goal of this research is to introduce the simulation studies of the vector-host disease nonlinear system (VHDNS) along with the numerical treatment of artificial neural networks (ANNs) techniques supported by Levenberg-Marquardt backpropagation (LMQBP), known as ANNs-LMQBP. This mechanism is physically appropriate, where the number of infected people is increasing along with the limited health services. Furthermore, the biological effects have fading memories and exhibit transition behavior. Initially, the model is developed by considering the two and three categories for the humans and the vector species. The VHDNS is constructed with five classes, susceptible humans , infected humans , recovered… More >

Abstract Breast cancer is the most common cancer in women and approximately 80% of patients will receive hormone therapy. If survival rate after breast cancer patients is the most important, their treatment, induces strong side effects on quality of life, including joint pain which is encountered by one woman in two. These joint pains are likely to reduce compliance with the treatment and consequently impact survival. In this context, this work aims to evaluate the potential benefit of adapted physical activity to relieve pain and its impact on daily functions. The APAISE protocol, described in this article, is a prospective observational… More >

Abstract

Nowadays, the zero liquid discharge of flue gas desulfurization (FGD) wastewater from coal-fired units has attracted the attention of all countries in the world. The pretreatment methods generally have the problems of high operation cost, small treatment capacity, and poor flexibility. However, the membrane method can avoid the above problems. In the current research, it has not been found that someone directly uses submerged ultrafiltration to pretreat FGD wastewater. Therefore, this paper innovatively proposed to directly use ceramic ultrafiltration membrane to treat FGD wastewater, which can ensure effluent quality and improve the flexibility of the pretreatment system. In this paper,… More >

Abstract The objective of the present study is to elucidate the effect of peroxide treatment and graft copolymerization on water absorption behavior of soy protein fi bers in order to make them suitable as a reinforcing material. Grafting of poly(methyl acrylate) and copolymers was successfully carried out on peroxide-treated soy protein fi bers. Different reaction parameters were optimized in order to get maximum percentage grafting. The grafted fi bers were evaluated for water absorption behavior in deionized water. Maximum grafting has been found at 0.219 mol/l of methyl acrylate, 0.0096:0.145 mol/l of FAS:H₂O₂ , 323 K, and 90minutes. Graft copolymerization results… More >

Abstract Oligomer systems based on poly(lactic acid) (PLA), poly(glycolic acid) (PGA), poly(butylene succinate) (PBS) and poly(butylene adipate) (PBA) were impregnated in wood and polymerized in situ to improve the dimensional stability of the treated wood. Dynamic mechanical thermal analysis (DMTA) was used to characterize the impact on the treated wood properties. Cell wall bulking treatments (PLA and PGA oligomers: OLA and OGA) induced softening and plasticization of wood components. Lumen fi lling treatments (PBS and PBA oligomers: OBS and OBA) led to minor decreases in treated wood stiffness with any softening dependent on the polymer melt temperature. Overall, no oligomer treatment… More >
