From Classroom to Career in Sibiu Romania – Engineering Students’ Perception on Internships and School Practices

2019

Abstract This article aims to highlight the most important ideas about internships and school practices from students’ point of view. The paper is structured in three parts. In the first section the topic based on building a career in Romania while being a student is discussed along with the employers’ expectations of having experience for getting a job and the problematic of today educational system. Further on the differences between traineeships and internships are detailed according to the Romanian framework and international sources to see exactly what do these mean and which one weights more for a company at the time of interviewing. Taking into the account what has been mentioned a s…

Oxidation, efflux, and isotopic fractionation of methane during autumnal turnover in a polyhumic, boreal lake

2007

[1] We studied the oxidation and efflux of methane (CH4) in a small, polyhumic lake, Mekkojarvi (southern Finland), during 6 weeks in autumn when the stability of the water mass first weakened, temporarily restabilized, and finally mixed completely. During the summer stratification period, CH4 had accumulated in the anoxic hypolimnion to high concentrations (>150 mmol m−3). Gradual mixing of the water column during the autumn allowed access to both oxygen and CH4 by aerobic methane-oxidizing bacteria (MOB) deeper in the water column. Thus the bulk (∼83–88%) of the CH4 accumulated in the hypolimnion was subsequently consumed by MOB while only 12–17% was lost from the lake to the atmosphere a…

Precambrian crustal evolution and continental drift

1981

One of the major questions of Precambrian research is whether present-day plate tectonic models can be applied to the evolution of the ancient continental crust or whether the tectonic style suggests a unidirectional and therefore non-uniformitarian development in response to gradual changes in the global thermal regime through time.

Modeling suggests that oblique extension facilitates rifting and continental break-up

2012

[1] In many cases the initial stage of continental break-up was and is associated with oblique rifting. That includes break-up in the Southern and Equatorial Atlantic, separation from eastern and western Gondwana as well as many recent rift systems, like Gulf of California, Ethiopia Rift and Dead Sea fault. Using a simple analytic mechanical model and advanced numerical, thermomechanical modeling techniques we investigate the influence of oblique extension on the required tectonic force in a three-dimensional setting. While magmatic processes have been already suggested to affect rift evolution, we show that additional mechanisms emerge due to the three-dimensionality of an extensional syst…

Carbon use efficiency variability from MODIS data

2017

[EN] Carbon use efficiency (CUE) describes how efficiently plants incorporate the carbon fixed during photosynthesis into biomass gain and can be calculated as the ratio between net primary production (NPP) and gross primary production (GPP). In this work, annual CUE has been obtained from annual GPP and NPP MODIS products for the peninsular Spain study area throughout eight years. CUE is spatially and temporally analyzed in terms of the vegetation type and annual precipitation and annual average air temperature. Results show that dense vegetation areas with moderate to high levels of precipitation present lower CUE values, whereas more arid areas present the highest CUE values. However, th…

Factores que determinan los honorarios de auditoría: Análisis empírico para México

2012

La escasa investigación internacional sobre auditoría en el ámbito latinoamericano ha motivado el desarrollo de esta investigación. El objetivo de este trabajo es analizar empíricamente los factores que influyen en el monto de los honorarios de auditoría en México, partiendo de una muestra de 59 empresas que cotizan en la Bolsa Mexicana de Valores (BMV), durante el período de 2002 a 2008. La metodología empleada, en línea con los estudios previos, se basa en un modelo de regresión múltiple, a partir de un conjunto de hipótesis relacionadas con diversos factores que afectan la determinación de los honorarios, vinculados a la empresa auditada y a la firma auditora, recolectados de la base de …

El reto de la competitividad y sostenibilidad para los destinos turísticos

2015

Desde la segunda mitad del siglo pasado, la actividad turística ha ido ganando peso entre las actividades productivas de países y regiones a escala mundial. Aunque tradicionalmente se ha identificado el crecimiento económico con la expansión de la industria, ya en las últimas décadas del siglo XX la actividad turística se consolidó como un sector productivo más, con capacidad para generar empleo y renta. Las características de esta actividad permiten que se desarrolle, con mayor o menos intensidad y éxito, en áreas excluidas de la expansión de la actividad industrial. Es más, se ha convertido en una oportunidad para áreas castigadas por la desindustrialización y en una actividad complementa…

Revising midlatitude summer temperatures back to A.D. 600 based on a wood density network

2015

Annually resolved and millennium-long reconstructions of large-scale temperature variability are primarily composed of tree ring width (TRW) chronologies. Changes in ring width, however, have recently been shown to bias the ratio between low- and high-frequency signals. To overcome limitations in capturing the full spectrum of past temperature variability, we present a network of 15 maximum latewood density (MXD) chronologies distributed across the Northern Hemisphere extratropics. Independent subsets of continental-scale records consistently reveal high MXD before 1580 and after 1910, with below average values between these periods. Reconstructed extratropical summer temperatures reflect n…
