A fenntartható élelmiszer-fogyasztás jövőbeli trendjei közé tartozik többek között a rövid élelmiszer-ellátási láncok terjedése, amely párosul fogyasztói magatartás megváltozásával: például termékinformációk iránti növekvő érdeklődés, helyi termelők és helyben előállított élelmiszerek bizalom. szakirodalom egyre többet foglalkozik vagy alternatív élelmiszerekkel, amelyek vásárlói „fekete dobozn...

Industrial sector plays a vital role in any economy by providing large number of employment and contributing the growth development. The emergence women entrepreneurs has given rise to an evolving perspective field entrepreneurship. However, constitute almost half population country but their participation business activities is still very low. They face various gender specific challenges while...

The use of any optical system, including fibers, for frequency conversion relies on the ability to satisfy so-called phase-matching conditions, which depend critically on the dispersive properties of the system, and on strong enough nonlinearity to allow a reduction in the threshold pump power. The recent surge of interest in theoretical and experimental studies of optical parametric processes ...

In the minimal supersymmetric standard model, the Higgs sector has two unknown parameters, usually taken to be tanβ ≡ v2/v1 and mA, the mass of its one physical pseudoscalar particle. By minimizing the minimum of the Higgs potential along a certain direction in parameter space, it is shown that mA = MZ + radiative correction, and if one further plausible assumption is made, tanβ > √ 3. If there...

We compare, using a three neutrino analysis, the allowed neutrino oscillation parameters and solar neutrino fluxes determined by the experimental data available Before and After Neutrino 2004. New data available after Neutrino 2004 include refined KamLAND and gallium measurements. We use six different approaches to analyzing the KamLAND data. We present detailed results using all the available ...

A system was designed for the continuous surface monitoring of hydrological, bio-optical, and biogeochemical properties in the vicinity of the Almeria-Oran jet-front system (Northwestern Mediterranean Sea). This system included a thermosalinograph, a fluorometer, an optical particle counter, and an absorbance-attenuance meter (AC9), allowing the estimation of the absorption [a(l), (m21)] and sc...

Organic chelators that are thought to be of recent biological origin control copper speciation in seawater. Previous studies have often resolved these copper binding ligands into two classes, class 1 ligands (conditional stability constants 1012–1014 M21) and class 2 ligands (conditional stability constants 109–1012 M21). At present the sources and structures of these chelators are unknown. Pre...

ABSTRACT This study investigates biases in tax decisions. In a series of four laboratory experiments with 303 students and 62 professionals, we document systematic tax-rate bias decisions under time constraints. Specifically, decision makers overestimate the relevance less complex information compared to more tax-base information. behavior leads suboptimal We also find that making, on average, ...

The purpose of this paper is to investigate the relationship between leverage and its main determinants in Argentine context, using trade-off theory pecking order theory. Studies that have addressed issue emerging economies are still quite rare results incomplete controversial. To identify companies be analyzed, we used a stratified sampling methodology, following an economic criterion. balance...
