Densities, excess molar volumes, and partial molar volumes for binary mixtures of water with monoethanolamine, diethanolamine, and triethanolamine from 25 to 80°C

Abstract: We have measured densities of binary mixtures of water with monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA) over the full range of compositions and over the temperature range from 25 to 80°C. Results of these measurements have been used in calculating excess molar volumes and partial molar volumes. Knowledge of the volumetric properties of these mixtures is useful in connection with industrial treatment of acidic gases; derived excess molar volumes and partial molar volumes can be used as a basis for understanding some of the molecular interactions in water-organic mixtures.

Mechanism Action of Platelets and Crucial Blood Coagulation Pathways in Hemostasis.

Abstract: Blood is considered to be precious because it is the basic necessity for health; our body needs a steady provision of oxygen, supplied via blood, to reach billions of tissues and cells. Hematopoiesis is the process that generates blood cells of all lineages. However, platelets are the smallest blood component produced from the very large bone marrow cells called megakaryocytes and they play a fundamental role in thrombosis and hemostasis. Platelets contribute their hemostatic capacity via adhesion, activation and aggregation, which are triggered upon tissue injury, and these actions stimulate the coagulation factors and other mediators to achieve hemostasis. In addition, these coordinated series of events are the vital biological processes for wound healing phases. The aim of this review is to summarize and highlight the important pathways involved in achieving hemostasis that are ruled by platelets. In addition, this review also describes the mechanism action of platelets, including adhesion, activation, aggregation, and coagulation, as well as the factors that aid in hemostasis and wound healing.

Sustainable product design and development: A review of tools, applications and research prospects

Abstract: Due to increasing pressure for achieving sustainability objectives, the concept of sustainable product design and development is gaining more attention in recent research. In the past, a plethora of eco-design tools that address only the environmental aspect have been developed. Hence, previous review articles focused mainly on eco-design tools, such as life cycle assessment (LCA) and others. Unlike previous studies, the main contribution of this article was to review and analyze the recent and emerging product design tools (published from 2007 to 2017) which considered other dimensions of sustainability along with the environment. Based on the criteria of sustainability dimensions, this paper proposed a generic and broader classification scheme to enhance the understanding of these recent tools. Those which included two aspects of sustainability were categorized as partial sustainable product design (P-SPD) tools, and those which covered three aspects of sustainability were classified as sustainable product design (SPD) tools. The analysis revealed that SPD tools were less mature and standard as compared to P-SPD tools. The majority of both P-SPD and SPD tools were based on a life cycle perspective. However, P-SPD tools were found to be more useful at early design stages. In addition, this paper presented the case studies of the tools to decipher their practical utility. It also discussed the hurdles and problems associated with the methodological development and practical utility of the tools. Founded on these difficulties, future research directions were presented. In essence, a coordinated and responsible effort among practitioners, governments, societies and researchers is needed to ensure the successful implementation of the tools.
