Wax esters are long-chain esters that have been widely applied in premium lubricants, parting agents, antifoaming agents and cosmetics. In this study, the biocatalytic preparation of a specific wax ester, cetyl octanoate, is performed in n-hexane using two commercial immobilized lipases, i.e., Lipozyme(®) RMIM (Rhizomucor miehei) and Novozym(®) 435 (Candida antarctica). Response surface methodo...

In the Year of Grace 1889, Dr. D. Montgomery Paton, armed with an L.R.C.P. et S. Edin., etc., went forth into the world to practise medicine. In first nine years he practised his profession on orthodox lines?this much we arc told?and we hope that his patients played the game and reacted in the orthodox manner to his treatment. Then it began to dawn on Dr. Paton that there was more in medicine t...

Monolithic neural networks and end-to-end training have become the dominating trend in field of deep learning, but steady increase complexity costs has raised concerns about effectiveness efficiency this approach. We propose modular as an alternative strategy for building by composing modules that can be trained independently then kept future use. analyse requirements challenges regarding modul...

Tool steel for hot working is usually used the rolls of conventional twin-roll casters aluminum alloys. In a vertical high-speed caster, copper are to rapidly solidify alloys and increase casting speed, since thermal conductivity higher than that tool steel. However, degree superiority over not clear. present study, effect roll material on strip solidification between caster was investigated by...

Post-orogenic extension in back-arc regions is classically associated with metamorphic core complexes (MCCs) cored exhumed rocks and granitic intrusions interacting low-angle detachments. When additional heat provided by the advected asthenosphere below extending region, for instance above slab tears, high-temperature migmatite-cored domes composite are emplaced whose geometry kinematics of emp...

The Canadian Superior Province has become one of the key test pieces to discuss tectonic processes and mechanisms crustal growth in Late Archean. consists a >2.8 Ga proto-cratonic core intruded by voluminous arc-like plutons surrounded series narrow, elongate ca. 2.8–2.7 juvenile belts, also referred as terranes or domains. seem wrap around generally young outward, but kinematics geodynamic cau...

Design methodology and criteria to configure sprue bush for enhancing functionality is systematically compiled from plastic injection moulding machine perspective. Sprue conduit’s sensitivity to moulding objectives are quantitatively ghettoised as expansion ratio on the basis of ubiquitous empirical relationships. This generic, simple, inexpensive preventive criterion enables sprue bush conduit...

A broader perspective on the role of cities and their relation to their inhabitants and the planet is essential to effectively answer urgent sustainability questions that emerge in and beyond cities. This essay provides a critical reflection on the notion of the sustainable city. The central question discussed is: how can the ideal of a sustainable city be best conceptualised? Through exploring...
