Design of Photovoltaic System for Rural Electrification in Rwanda
2017
Master's thesis Renewable Energy ENE500 - University of Agder 2017 In this century of accelerated development in various domains, some African countries are still facing a challenge of lack of power due to its scarce in some places, where by the main source of power (generation of electricity) is hydro since thermal and fuel are still on a small scale. This problem results in less productivity and economic decline of some countries like Rwanda which is among African countries that are at a very high speed in development, the grid lines from distant places are stack and they are few compared to the need of electricity in all corners of the country, especially in rural areas whereby each hous…
Granulometry, mineralogy and trace elements of marine sediments from the Gulf of Milazzo (NE Sicily): evaluation of anthropogenic impact
2010
Granulometry, mineralogy, and trace element concentrations are determined in marine sediments from thirty-six sampling sites in the littoral environment of the Gulf of Milazzo (NE Sicily). Sediment samples were collected in August 2008, along 18 seaward transects, at water depths of ‐10, ‐20 and ‐30 m, by using a Van Veen grab. Grain-size analysis shows predominance of sand (56%) and silt (35%) fractions with respect to clay (7%) and gravel (2%) fractions. Bulk mineralogical analysis documents the presence of quartz, micas, feldspars, calcite, and chlorite, which reflect erosion processes affecting the Kabilian-Calabrian Units. Concentrations of most trace elements in the deeper sediments w…
Die Einschätzung des Rückfallrisikos bei sexuell auffälligen Kindern und Jugendlichen anhand standardisierter Prognoseinstrumente
2014
In der vorliegenden Untersuchung wurde überprüft, ob standardisierte Prognoseinstrumente in der Lage sind, erneute Auffälligkeiten in einer Stichprobe von sexuell auffällig gewordenen Kindern und Jugendlichen (N = 80; als Einschlusskriterium musste keine Verurteilung erfolgt sein) vorherzusagen. Eingesetzt wurden die international als etabliert geltenden Verfahren Structured Assessment of Violence Risk in Youth (SAVRY), Estimate of Risk of Adolescent Sexual Offense Recidivism (ERASOR) und Juvenile Sex Offender Assessment Protocol-II (J-SOAP-II). Die Ergebnisse der vorliegenden Studie zeigen, dass die ursprünglich für junge bzw. jugendliche Sexualstraftäter entwickelten Instrumente auch bei…
Abrikossoff-Granulosazelltumor: Ein seltener Tumor des Oesophagus
1997
Es wird uber einen 41 jahrigen Patienten berichtet, bei dem eine abdominothorakale Oesophagusresektion durchgefuhrt wurde nachdem ein Granulosazelltumor der Speiserohre in der praoperativen Diagnostik als malignes Plattenepithelcarcinom verkannt worden war. Granulosazelltumoren des Oesophagus sind sehr seltene zumeist benigne Tumoren neuroektodermalen Ursprungs. Die Diagnose ergibt sich aus dem endoskopischen Aspekt und der histologischen Untersuchung und immunohistochemischen Aufarbeitung des Biopsats. Aufgrund der histologischen Eigenart des Tumors besteht Verwechslungsgefahr mit Plattenepithelcarcinomen.
Successive alkalinity producing system for the treatment of acid sulphate soil runoff: preliminary results of a field trial
2005
A successive alkalinity producing system (SAPS) has been investigated as a potential passive treatment option for acid, metal containing runoff from acid sulphate soil. A pilot-scale system was installed at an agricultural land site in Rintala embankment area in mid-western Finland. The experimental layout consists of three parallel treatment units: two different SAPS cells and one limestone-filled cell for comparison of performance. The SAPS cells are composed of a bottom layer of limestone and a top layer of compost supplemented with sand. One of the SAPS cells contains sulphate-rich, waste gypsum mixed with the compost layer in order to enhance the metal reduction by sulphate reducing-ba…
When does Regression discontinuity design work? Evidence from random election outcomes
2018
We use elections data in which a large number of ties in vote counts between candidates are resolved via a lottery to study the personal incumbency advantage. We benchmark non‐experimental regression discontinuity design (RDD) estimates against the estimate produced by this experiment that takes place exactly at the cutoff. The experimental estimate suggests that there is no personal incumbency advantage. In contrast, conventional local polynomial RDD estimates suggest a moderate and statistically significant effect. Bias‐corrected RDD estimates that apply robust inference are, however, in line with the experimental estimate. Therefore, state‐of‐the‐art implementation of RDD can meet the re…
Necessidade do controlar de oficio as cláusulas abusivas nos contratos com consumidores: Estudo comparado com o sistema espanhol
2016
Las autoridades europeas abogan por dotar al juez de mayores facultades para controlar ex officio la inclusión de cláusulas abusivas en los contratos de adhesión celebrados entre empresarios y consumidores. Una línea jurisprudencial incorporada en España, mejorando así la tutela y protección de los derechos e intereses de los consumidores. No obstante, países como Uruguay no contemplan esta posibilidad, impidiendo al juez realizar un control de contenido cuando no haya sido solicitado por las partes puesto que se cuestiona su anulación debido a la propia naturaleza de la nulidad. En el presente artículo analizamos las diferentes regulaciones de las cláusulas abusivas en los ordenamientos es…

Purpose: The purpose of the studyis to investigate and describe the experiences different leaders (Head of unit) have with the…
Selective MicroRNA-Offset RNA Expression in Human Embryonic Stem Cells
2015
Small RNA molecules, including microRNAs (miRNAs), play critical roles in regulating pluri-potency, proliferation and differentiation of embryonic stem cells. miRNA-offset RNAs (moRNAs) are similar in length to miRNAs, align to miRNA precursor (pre-miRNA) loci and are therefore believed to derive from processing of the pre-miRNA hairpin sequence. Recent next generation sequencing (NGS) studies have reported the presence of moRNAs in human neurons and cancer cells and in several tissues in mouse, including pluripotent stem cells. In order to gain additional knowledge about human moRNAs and their putative development-related expression, we applied NGS of small RNAs in human embryonic stem cel…
