Production of green surfactants: Market prospects     

《Electronic Journal of Biotechnology》2021

Science has greatly contributed to the advancement of technology and to the innovation of production processes and their applications. Cleaning products have become indispensable in today’s world, as personal and environmental hygiene is important to all societies worldwide. Such products are used in the home, in most work environments and in the industrial sectors. Most of the detergents on the market are synthesised from petrochemical products. However, the interest in reducing the use of products harmful to human health and the environment has led to the search for detergents formulated with natural, biodegradable surfactant components of biological (plant or microbiological) origin or chemically synthesised from natural raw materials usually referred to as green surfactants. This review addresses the different types, properties, and uses of surfactants, with a focus on green surfactants, and describes the current scenario as well as the projections for the future market economy related to the production of the different types of green surfactants marketed in the world.How to cite: Farias CBB, Almeida FCG, Silva IA, et al.

Genetic variation in the angiotensin II type 1 receptor (AT1R) has an important effect on the outcome of acute coronary syndrome (ACS) initiated treatment with captopril. This study aims to investigate the impact of genetic polymorphism of AT1R (rs5186 and rs275651) on the ACS outcome in Iraqi patients treated with captopril. A total of 250 Iraqi individuals with ACS were included in this case—control study and they were divided into two study groups; Study group 1 included 125 participants who were prescribed captopril, 25 mg twice daily and study group 2 included 125 participants who received no captopril as part of their ACS treatment (control study). The AT1R gene (rs5186) CC genotype was found to be associated with ST-elevation myocardial infarction (STEMI) (Odd’s ratio (O.R) = 1.2, P = 0.7), while AC was associated with Non-ST-elevation myocardial infarction (NSTEMI) and unstable angina (UA) (O.R = 1.2, P = 0.8). AC genotype is more prone to have Percutaneous coronary intervention (PCI) after ACS attack (O.R = 1.2, P = 0.6). CC genotype had a risk to get less improvement (O.R = 1.6, P = 0.5), so might require higher doses of captopril during acute coronary insult. The AT1R gene (rs275651) AA genotype was associated with UA (O.R = 1.3, P = 0.9). AA and AT genotypes were more prone to have PCI after ACS attack (O.R = 3.9 P = 0.2, O.R = 3.5, P = 0.3 respectively) and thus requiring higher doses of captopril. We conclude that the AT1R rs5186, rs275651 genetic polymorphisms might partially affect the clinical outcome of ACS patients treated with captopril and might have captopril resistance which requires higher doses.  相似文献   

对天水市国有工业企业增长能力的财务分析     

何建华  王建强 《天水师范学院学报》2003,23(5):50-52

天水国有工业企业中存在的财务问题主要表现在资产内部结构不合理，所有者权益比重过低，产品销售成本过高等几个方面。天水国有工业企业应积极调整资产内部结构，实行企业产权多元化，增加所有者权益在资产总额中的所占比重，降低负债率，进一步提高企业资产增长能力；并在调整产品结构、拓展市场、增加产品销售收入的同时，严格控制产品销售成本，努力增加产品销售利润，提高企业收益增长能力。  相似文献

Ein graphbasiertes Managementsystem für dynamische Entwicklungsprozesse     

Bernhard Westfechtel 《Informatik - Forschung und Entwicklung》2001,16(3):125-144

Zusammenfassung. Wir pr?sentieren ein Managementsystem, das insbesondere hinsichtlich der Dynamik von Entwicklungsprozessen über die Funktionalit?t kommerzieller Systeme zum Projektmanagement, Workflowmanagement und Engineering Data Management hinausgeht. AHEAD (Adaptable and Human-CenteredEnvironment for the MAnagement of Development Processes) unterstützt die Koordination von Entwicklern durch integriertes Management von Produkten, Aktivit?ten und Ressourcen. Für das Management von Aktivit?ten werden dynamische Aufgabennetze angeboten, die sich durch nahtloses Verschr?nken von Planen, Analysieren und Ausführen auszeichnen. Alle Managementdaten (z.B. Aufgabennetze, Versionshistorien oder Produktkonfigurationen) werden intern in einheitlicher Weise durch Graphen repr?sentiert. Managementwerkzeuge werden aus einer formalen Spezifikation generiert, die auf programmierten Graphersetzungsregeln basiert. Eingegangen am 9. Juni 2000 / Angenommen am 20. M?rz 2001  相似文献
