Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This research analyses the carbon footprint of the NGO Madre Coraje, using an integrated methodology that combines the calculator provided by REAS (Red de Economía Alternativa y Solidaria) Navarra and the Life Cycle Assessment (LCA). It quantifies emissions across the three scopes of the Greenhouse Gas Protocol, evaluating both direct and ...

Computational morphogenesis of free form shells: Filter methods to create alternative solutions [PDF]
, 2009 p. 536-547Actual trends in numerical shape optimal design of structures deal with handling of very large dimensions of design space. The goal is to allowing as much design freedom as possible while considerably reducing the modelling effort.

EFFECT OF METALLIC SOAPS ON POLYMERISATION
, 1953 Effect of a few oil-soluble, surface-active agents and the oleates of Cr, Ag, Cd, Pb, Cu on the benzoyl peroxide catalysed polymerisation of styrene in solution and that of the soaps of Mn, Zn, Cd, Co, Ni, Al, Fe etc. on the polymerisation of methyl methacrylate and styrene in absence of peroxide catalyst have been studied.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A bilayer protection approach is proposed for slowing down the surface potential decay of thin films of spontaneously‐polarized electret materials. The electret and the protective films are characterized, and the protection effectiveness is investigated under the effects of light illumination, water contact and mechanical impact.

Food Chemistry International, EarlyView.In an aqueous alkaline medium, fatty acids (from the hydrolysis of triglycerides or freely present in the oil) are ionised in order to form emulsifiers (carboxylates) which will physically stabilise the prepared emulsion. The higher the free fatty acids content of the oil and alkalinity of the solution, the higher will be the stability of the prepared ...

NIPPON KAGAKU KAISHI, 1991 非水系での酸化ジルコニウム(IV)単分散微粒子調製の一方法として,高級アルコール中に分散させたジルコニウムセッケンの加熱分解法を試み,金属アルコキシド分解法からのものとの比較を行った。金属セッケンは,脂肪酸の総炭素数C12,C14,C16,C18のものを,媒質のアルコールは総炭素数C8,C10,C12,C14のものを用いた。媒質中に分散させたジルコニウムセッケンの懸濁を120～200℃の温度範囲で一定時間,一定温度下で加熱することにより,ZrO2の微粒子を含む安定なオルガノゾルを得た。系から析出する微粒子は,ほぼ球状で,平均粒子半径は0.4～0.1μmであった。また加熱温度が高くなると単分散性がよくなり,金属セッケンの炭素数が増すと平均粒径が減少する傾向を示した ...

Multilayer Cellulose Acetate–Viscose Films for Bio‐Based, Bio‐Degradable Packaging Applications
Packaging Technology and Science, EarlyView.Cellulose acetate (CA) and cellulose foils stick together comprehensively after mild cellulose sodium hydroxide treatment and heated compression. For combined foils, water barrier properties correlate with CA thickness. Oxygen permeation suffers due to the sodium hydroxide pre‐treatment induced foil changes. The composite represents a biodegradable and
