Mathematics Skills of Kosovar Primary School Children: A Special View on Children with Mathematical Learning Difficulties
2018
The present study examined the development of mathematics skills of Kosovar primary school children in terms of their gender, living area, socio-economic status, and achievement level. A special emphasis was placed on longitudinal investigations of the development of mathemat-ics skills in children with learning difficulties in mathematics over a 2-year and 4-month period. Participants were 553 fourth-graders, 85 of whom identified with mathematical learning difficulties were classified into two subgroups: children with low mathematics achievement and children with limited mathematics ability. Results have shown that there were no gender differences in mathematics achievement. Children’s li…
Risk assessment of information on the subcombination Bt11 × 1507 × GA21, related to the application of Syngenta (EFSA‐GMO‐DE‐2011‐99) for authorisati…

Efsa Panel On Genetically Modified Organisms (gmo)StatementRequestor: European CommissionQuestion number: EFSA-Q-2016-00730; The EFSA Panel on Genetically Modified Organisms (GMO) has previously assessed the single events Bt11, MIR162, MIR604 and GA21 as well as different stacked events corresponding to combinations of these events. These maize events were found to be as safe as their conventional counterparts and other appropriate comparators with respect to potential effects on human and animal health and the environment. In its assessment of the four-event maize stack Bt11 9 MIR162 9 MIR604 9 GA21, the GMO Panel also assessed all the subcombinations of these events not previously assesse…
Effect of Stacking Sequence and Sodium Bicarbonate Treatment on Quasi-Static and Dynamic Mechanical Properties of Flax/Jute Epoxy-Based Composites
2019
The present paper deals with the investigation of quasi-static and dynamic mechanical response of epoxy-based composites reinforced with flax and/or jute plain weave fabrics. In order to evaluate the influence of the stacking sequence, two monolithic laminates reinforced with flax or jute fibers and two hybrid flax/jute laminates were manufactured through the vacuum infusion technique. Furthermore, an eco-friendly and cost-effective surface treatment based on fiber soaking in a sodium bicarbonate solution was employed to improve the fiber-matrix adhesion. The mechanical characterization (by means of quasi-static flexural, dynamic mechanical thermal analysis and Charpy impact tests) allowed …
Effects of the Extraction Technology on Pomegranate Juice Quality
2020
Pomegranate juice is a rich source of phenolic components; its consumption has considerably increased throughout the world in recent years, due to its nutraceutical properties. Commercial juice production involves pressing the fruits. The aim of this study was to assess the influence of the pressing stage on pomegranate juice properties, in terms of value, duration of the applied pressure and juice yield in order to examine the influence of pressure level on volatiles and nutraceutical properties of the juice. Pomegranate fruits cv. Wonderful One were manually harvested and mechanically processed for extracting the juice by means of a shelling machine, a peristaltic pump and a pneumatic pre…
Comparative study between different methods for the efficiency of the production activity in the wood industry
2017
Generally speaking, the quality and cost of goods and in particular of the wood products is a decisive condition in their sales on the market, attracting buyers to satisfy their wishes and requirements. Starting from the general idea, by which it is considered that the manufacturing activity is effective if production is obtained at maximum quality with a low (minimum) cost, or when the revenue from the sale of products exceeds the market expenditure which is necessary to achieve it, this research article aims to study ways to make production more efficient by methods which could also be applied in the wood industry, by presenting a comparative study on production optimization methods in th…
Relaxed and connected: Insights into the emotional–motivational constituents of musical pleasure
2018
Music is a source of daily pleasure, and positive emotional experiences and rewarding functions of music have been actively studied. Yet, knowledge about the interrelatedness of emotional and motivational constituents of musical pleasure is sparse. This study explored the characteristic emotional contents of music-induced pleasure, their relation to motivations for music and whether the underlying dimensionality of these aspects was specific to music (in comparison to the visual domain). Data were collected through an online questionnaire ( N = 464), measuring evoked emotions and motivational pleasure types that the respondents related to a musical piece or a visual object inducing pleasur…
Measuring integration in new countries of immigration
2018
Abstract The purpose of this study is to develop a framework to measure immigrant integration in emerging immigrant destinations. After several decades of intensive research, the definition and assessment of immigrants’ integration remains elusive. Increasingly more attempts have been made to foster scientific progress in the field in the las decades. Yet, immigrant integration in emerging destination countries remains particularly little studied despite several calls for more research on the topic. The developed integration framework (i.e. the Integration Score) is composed of 6 dimensions and 24 indicators of integration (4 indicators for every dimension). To empirically test the validity…
El rol del asociacionismo de inmigrantes africanos en la construcción de cohesión social y la convivencia en Cataluña, Navarra y la Comunidad Valenci…
2013
This article aims to analyse some possible contributions from organisations funded by immigrants from the African continent to the socio-cultural integration in three Regions in Spain. In order to do so, first there is a definition of integrations as a process, paying special attention to the role that national and international literature have given to the associations of immigrants. Afterwards, there is a focus on associations from people with an African origin, paying attention to the double view point, from one side the one from representatives from African associations and on the other, from administration technicians and representatives of social entities that collaborate with them. T…
Advances of Research in Education and ICT in Hospital Classrooms
2017
Últimamente ha proliferado la utilización de aplicaciones didácticas digitales en torno a la educación del alumnado convaleciente. No obstante, son escasos los trabajos que han estudiado de forma global las tecnologías de la información y la comunicación (TIC) y sus materiales en las aulas hospitalarias (AH). Desde ese punto de vista, hemos realizado un análisis de los avances alcanzados en las investigaciones desarrolladas sobre experiencias educativas, evaluando el impacto de las TIC y comprobando que el alumnado hospitalizado puede conectarse con la comunidad educativa y su entorno. La metodología llevada a cabo ha sido la revisión bibliográfica que nos ha permitido organizar, clasificar…
Research on the machining process modeling of a rotational mold using CAM applications
2021
Rotational molding is a unique process, with a high growth rate, which allows the use of geometries and materials adapted to particular needs. It is superior to other manufacturing methods in terms of low cost, break-even point and size of parts that can be manufactured. Rotational molding products are often a substitute, with a lower mass, for traditionally used materials. In this scientific paper it is analyzed the recent literature related to the field of rotational molding processes. It also addresses the issue of processing a rotational mold, with the main purpose of optimizing the cutting regime. In this context, it is highlighted the way of processing the surface of the outer mold ba…
