Effect of sample preparation on gel permeation chromatography results of determination of molecular weight of polyethylene obtained with using of zir…

2003

Molecular weights of polyethylene (PE) obtained with using of zirconocene catalyst activated with large excess of methylaluminoxane (MAO) were determined by gel permeation chromatography (GPC) method. It was found that repeatability of the measurements is strongly influenced by MAO remained in PE samples as well as time of sample keeping in the apparatus (dissolution + measurement time) at temp. 142 °C. A method of MAO removing from PE samples, before GPC measurement, based on additional washing of the sample with HF in methanol solution has been proposed. This modification leads to better both authenticity and repeatability of the results. Studies on the influence of time of sample keeping…

Bordón : revista de pedagogía

2014

Resumen tomado de la publicación. El artículo forma parte de un monográfico titulado : educación supranacional. Se analiza cómo, a partir de los discursos en materia de política educativa establecidos en torno a la literatura de género y a términos como “capacitación de género” y “equidad de género”, así como la consolidación de políticas de mainstreaming (transversalidad de la perspectiva de género) se lleva a reconocer, a través de la Educación Comparada, interesantes hallazgos en este ámbito de estudio e investigación, con un revelador estado de la cuestión supranacional. Desde el enfoque de los sistemas educativos actuales se legitiman, en efecto, las consecuencias de la política global…

External Developmental Assets and Positive Identity Among Emerging Adults in Norway, Romania, Slovenia, and Turkey

2021

The present study adopts The Developmental Assets and Positive Youth Development (PYD) perspectives which (in contrast to the deficit-based approaches which highlight risks and deficit in youth development) claim that young people have potencies to achieve optimal development if supported by their social environment. Extant research indicates that developmental assets are linked with a variety of thriving indicators. The present research aimed to contribute to the PYD research by examining the external developmental assets (support, empowerment, and boundaries and expectations) emerging adults (N= 2055; age range = 18–28) perceived in their social environment and the level of their positive…

El potencial vestibular miogénico evocado cervical en la enfermedad de Ménière

2015

Introducción La enfermedad de Ménière (EM) es una afectación del oído interno de etiología desconocida que clínicamente se manifiesta por crisis recurrentes de vértigo, sensación de plenitud ótica, pérdida de audición y acúfenos. Su base fisiopatológica es el hidrops endolinfático (HE), debido a la dilatación del laberinto membranoso por un aumento del volumen de la endolinfa en relación con la perilinfa. La EM representa del 3-11% de los diagnósticos en Otoneurología. En España se realizó un estudio epidemiológico en Cantabria en 2003 resultando una incidencia de 3 casos por 100.000 habitantes/año, una prevalencia de 75/100.000, con predominio en el sexo femenino (29 en varones y 46 en muj…

Architettura e Potere. Peter Eisenman, intervista di Gregorio Carboni Maestri e Simona de Simoni.

2012

La relazione tra architettura e potere risulta complessa da molti punti di vista. Ogni forma di potere, infatti, rappresenta e amministra se stessa attraverso dispositivi spaziali e architettonici. Lei come interpreta questa relazione? Si potrebbe dunque sostenere che soltanto l'opera ha potere, ma non l'architetto?

Simulation of a Power Line Communication System in Medium and Low Voltage Distribution Networks

2011

The aim of the paper is to study the influence of the power transformer on signal transmission in the case of a power line communication (PLC) system in a overhead Medium Voltage (MV) power network. A model of the PLC system was carried out by means of the Simulink® software. A distributed parameter MV overhead line, two power transformers, the signal coupling networks and the receiving and transmitting line coupling interface of a ST7540 FSK powerline transceiver were included in the model. The performances of the complete PLC communication system are evaluated for different line lengths by means of the attenuation computed as ratio between the received and transmitted voltage signals.

Skolotāja valoda angļu valodas stundās pozitīvu attiecību veidošanai klasē

2017

Pētījums aplūko kā skolotāju klases valoda palīdz veidot pozitīvas savstarpējās attiecības klasē, jo pozitīvai atmosfērai klasē ir nozīmīga loma svešvalodu apguvē. Aptaujā – pētījumā tika izmantotas šādas datu ieguves metodes: anketas piekto līdz divpadsmito klašu skolēniem, angļu valodas stundu novērošanas pieraksti, intervijas ar angļu valodas skolotājiem. Iegūtie dati atklāj skolēnu viedokli par angļu valodas skolotājiem un angļu valodas stundām, norādot, ka skolotājiem ir nepieciešams vairāk domāt par visu skolēnu iesaistīšanu mācību stundā, skolotāja lietotās valodas sarežģītību un runas ātrumu, kā arī vienādu attieksmi pret visiem skolēniem. Novērojot angļu valodas stundas, autore pie…
