Melt Processed PCL/PEG Scaffold with Discrete Pore Size Gradient for Selective Cellular Infiltration

2016

In order to develop scaffold able to mimic the natural gradient properties of tissues, biphasic and triphasic approaches were adopted. In this work, polycaprolactone/polyethylene glycol (PCL/PEG) scaffolds were prepared by using a combination of melt mixing and selective leaching without harmful solvents. The method permitted to develop three-layer scaffolds with high control of porosity and pore size. The mechanical properties were evaluated under physiological condition in order to simulate the real conditions of work. Co-culture of osteoblastic and fibroblastic mice cells were carried out in order to study the differential cellular permeation through the different pore size layers.

Three-layered porous device in PCL/PEG blend for interface tissue engineering

2016

Tissue interfaces, such as cartilage-to-bone, exhibit anisotropic structural properties, which gradually vary from one tissue to another. Consequently a regenerative scaffold designed for interface tissues should exhibit a gradient in composition, structure and mechanical features, mimicking those of the native zones. In particular, the architecture of pores plays a central role. Indeed, a biomedical implant should be designed with porosityand pore size gradients simulating the structure of the two interface tissues. One of the most common techniques to prepare porous scaffolds is the particulate leaching method, which involves the selective leaching of a mineral or organic compound as poro…

Coping Strategies against peer victimization: differences according to gender, grade, victimization status and perceived classroom social climate

2021

The Sustainable Development Goals (SDGs) include “Good Health and Well-being” (SDG3) and “Quality Education” (SDG4). Nevertheless, many students cannot achieve these goals if they suffer peer victimization at their schools, and intervention programs to reduce it are necessary. These programs should consider the possible differences in the coping strategies preferred by students according to some personal (e.g., gender, grade, victimization status) and contextual (e.g., perceived classroom social climate) factors to be more effective. Therefore, the objective of this study was to analyze the possible differences in the coping strategies preferred by students (ask a friend for help, ask a tea…

The balancing act of teaching : a comparison between EFL teachers' views and a textbook analysis of the role of perceptual learning styles in Finnish…

2012

Suomessa vieraan kielen opiskelu aloitetaan tavallisimmin kolmannella luokalla, ja suurimmalle osalle oppilaista tämä kieli on englanti. Tällöin oppilas alkaa rakentaa kuvaa sekä englannin kielestä että itsestään englannin kielen opiskelijana. Onnistumisen kokemukset ovat tässä vaiheessa tärkeitä, ja yksi tapa niiden mahdollistamiseen on oppilaan oppimistyyliä vastaava opetus. Kolmannen luokan englannin oppitunneille osallistuu kuitenkin heterogeeninen ryhmä erilaisia oppijoita, minkä vuoksi on käytettävä vaihtelevia opetusmenetelmiä. Tässä tutkimuksessa keskityttiin seuraaviin oppimistyyleihin: visuaalinen, auditiivinen, kinesteettinen, taktiilinen sekä ryhmässä ja yksin oppiminen. Näistä …

Finnish Preschool and First-Grade Children's Use of Media at Home

2012

Publisher's PDF We investigated Finnish children’s use of print and electronic media in the home and their literacy development. Questionnaire data from 857 parents of preschoolers (collected in 2006 and 2007) and first graders (2008) showed that homes were well equipped with electronic media including Internet access in almost every home, although only a third of the children used the Internet. Television, print media, and videos/DVDs were more commonly used than computers. Most first graders but few preschoolers had mobile phones. Most parents read bedtime stories, had a sizable number of children’s books, and library visits were common. Boys´ and girls’ skills in reading did not differ a…

Differences between students' PISA reading literacy scores and grading for mother tongue and literature at school : A geostatistical analysis of the …

2016

In Finland, the national Core Curriculum for Basic Education defines the learning objectives along with the numerical grade to be given for good competence in each school subject in the final phase of basic education. While serving as a guideline for schools and teachers, it should also ensure an objective evaluation of all students in Finland. In this paper, we take a closer look at the equality of student assessment in Finland in the light of student performance in the Programme for International Student Assessment (PISA) 2009. This study investigates the relationship between the grades given to students in mother tongue and literature at different schools and the same students’ reading l…

The study examines the stationary conditions, determine solutions to improve degraded land, assessing the cost of ecological restoration work needed in the area of improving degraded lands at Rapa - Copăcel, estimated benefits of the project and its viability. Objectives of the paper: need to introduce in the circuit of productive forest lands within the improvement of the area "La Rapa - Copăcel" danger zone where activation of the phenomena of degradation (erosion , landslides ) predominate. Out of 102.33 ha as area for improvement, the effective area of 101.6 ha is forested, representing a difference of 0.73 ha, 1.2 m wide strip that is to be the place for hedges.

The Prognostic Characteristics and Recurrence Patterns of High Grade Endometrioid Endometrial Cancer: A Large Retrospective Analysis of a Tertiary Ce…

2023

High grade endometrioid endometrial cancer (HGEEC) is a heterogeneous group of tumors with unclear prognostic features. The aim of the present study is to evaluate the independent risk factors for recurrence and mortality and to describe the recurrence patterns of HGEEC. Ninety-six consecutive cases of HGEEC treated with primary surgery in a single Tertiary Center were retrospectively reviewed. Clinicopathological and treatment details were recorded, and all patients were closely followed up. Disease-free, overall and cancer-specific survival rates were 83.8%, 77.8% and 83.6%, respectively. Cervical stromal involvement was independently related to recurrence (HR = 25.67; 95%CI 2.95–223.30; …

Self-regulatory Efficacy and Foreign Language Attainment

2016

The foreign language learning process is lengthy and full of obstacles, while the most significant learning effects are quite delayed in time, and difficult to notice on a day-to-day basis. For this reason perseverance in self-controlling efforts may be of crucial importance to language success. It allows for a steady linguistic and cultural development of the student, allowing him to enjoy diverse, even contradictory opinions, leading to ultimate language success. The results of the research carried out with Polish secondary grammar school students (N = 621) demonstrate that only in reference to self-assessment of FL skills students with high levels of self-regulated efficacy significantly…
