Depletion of delta 9 desaturase (EC 1.14.99.5) activity in lactating rat during protein restriction.

2000

The effects of protein restriction on the activity of delta9 desaturase (EC 1.14.99.5) were investigated in lactating rats. A control group was fed a balanced diet (20% casein) for 14 days, whereas the experimental groups were fed a low-protein diet (8% casein), supplemented with or without L-methionine (0.4%), for 14 days. The enzyme activity was measured by incubations of hepatic microsomal pellets with (1-14C) stearic acid. Results showed a decreased delta9 desaturase activity, after 2,7 and 14 days of depleted diet, of -50, -40 and -33% respectively, compared with control. The supplementation of the low-protein diet with 0.4% methionine, which favours food consumption as well as growth,…

Role of CD36 in Oral and Postoral Sensing of Lipids

2011

Obesity and associated plethora of diseases constitute a major public health challenge worldwide. The conjunction of profound changes in our lifestyle and a thrifty genetic that evolved in an environment of food scarcity largely explains this epidemic situation. Food abundance promotes our specific appetite for the more palatable food generally rich in lipids. It is noteworthy that this attraction for fatty food is not specific to humans. Rats and mice also spontaneously prefer lipid-rich food in a free-choice situation. Detection of lipids in food requires the presence of specific sensors located in strategic places (e.g., oral cavity, small intestine, brain) whose activation results in a …

The guardians of European football : UEFA Financial Fair Play and the career of social problems

2016

AbstractUEFA’s Financial Fair Play (FFP) policy represents a severe regulatory intervention in European club football competitions. While potential outcomes of the concept have been thoroughly assessed, there is little research on the genesis and background behind its implementation. The present paper fills this gap by analyzing the discourse in the run-up to the passage of FFP. We focus on interpreted practice and context and argue that the rising indebtedness of clubs and their increasing reliance on benefactors were a necessary but not sufficient requirement. Further ingredients imperative for the successful policy development were claims-making activities by influential actors to secure…

A Decision Model on Corporate Social Responsibility and Business Strategies

2017

The role of companies in today's society has been radically transformed, especially in developed economies. The stakeholders have deposited on companies different expectations compared to some years ago. Furthermore, this transformation has led to the establishment of new internal models of corporate governance depending on the intensity of the impact of demand for social action coming from the stakeholders interacting with firms. The aim of this work is to offer a decision model on Corporate Social Responsibility (CSR) and business strategies. This model constitutes a tool that can be adopted by firms, no matter their operational sector, to establish their particular coordinates with respe…

The Great Financial Crisis in Finland and Sweden: The Dynamics of Boom, Bust and Recovery 1985–2000

2009

This paper explores the anatomy of the boom, deep depression and recovery in the Finnish and Swedish economies in the period 1985-2000. These fifteen years are divided into three phases: (1) financial liberalization and the boom and the overheating of 1985-90, (2) the outbreak and spread of the crisis to all sectors of the economy in 1990-92, and (3) the recovery 1993-2000. Each period is analyzed separately.

Continuous flow synthesis of amine oxides by oxidation of tertiary amines

2019

The synthesis of N-methylmorpholine N-oxide by oxidation of N-methylmorpholine with hydrogen peroxide was implemented in a microstructured reactor for increased safety and larger-scale applications. The active oxidant, peroxymonocarbonate HCO4− is formed in situ from the equilibrium reaction of hydrogen peroxide and bicarbonate. The bicarbonate can be induced by hydration of carbon dioxide. Elaborate studies on the influence of the catalyst concentration and temperature were carried out and the observed activation energy was determined. Elevated temperatures up to 60 °C and a carbon dioxide concentrations of 1 wt% led to a conversion for N-methylmorpholine of approximately 98% within 13.90 …

A mathematical simulation of high temperature induction heating of electroconductive solids

2007

The mathematical model of non-stationary coupled electromagnetic and thermal processes in polarizable and magnetizable axisymmetric electroconductive solids subjected to electromagnetic field generated by external currents is proposed. The processes parameters are connected through heat sources and temperature dependence of material characteristics. The problem is solved by finite element method. The process of induction heating of a finite steel cylinder is considered.

A Photographic study of subcooled flow boiling burnout at high heat flux and velocity

2007

Abstract The present paper reports the results of a visualization study of the burnout in subcooled flow boiling of water, with square cross section annular geometry (formed by a central heater rod contained in a duct characterized by a square cross section). The coolant velocity is in the range 3–10 m/s. High speed movies of flow pattern in subcooled flow boiling of water from the onset of nucleate boiling up to physical burnout of the heater are recorded. From video images (single frames taken with a stroboscope light and an exposure time of 1 μs), the following general behaviour of vapour bubbles was observed: when the rate of bubble generation is increasing, with bubbles growing in the …

The Nukiyama Curve in Water Spray Cooling: its Derivation from Temperature-Time Histories and its Dependence on the Quantities that Characterize Drop…

2007

Abstract Heat transfer from hot aluminium walls to cold water sprays was investigated. The method used was the transient two-side symmetric cooling of a planar aluminium target, previously heated to temperatures of up to 750 K, by twin sprays issuing from full-cone swirl spray nozzles of various gauge. The target’s mid-plane temperature was recorded during the cooling transient by thin-foil K thermocouples and a high-frequency data acquisition system. In order to determine the wall temperature Tw, the wall heat flux q w ″ and the q w ″ - T w heat transfer (Nukiyama) curve, two different approaches were used: the first was based on the solution of an inverse heat conduction problem, the seco…
