Στη βάση των σύγχρονων θεωρητικών και παιδαγωγικών προσεγγίσεων, αναπτύσσονται κοινωνικοεποικοδομητικές και κοινωνικοπολιτισμικές μέθοδοι διδασκαλίας και μάθησης με την αξιοποίηση των Τεχνολογιών Πληροφορίας και Επικοινωνιών (ΤΠΕ). Με την οργάνωση ενός Διαδικτυακού Εκπαιδευτικού Κοινωνικού Δικτύου (ΔΕΚΔ) τα μέλη του μπορούν να λειτουργήσουν ως μία Ψηφιακή Κοινότητα Μάθησης (ΨΚΜ), μια κοινότητα ανταλλαγής γνώσεων, ιδεών, απόψεων, μεθοδολογιών, εργαλείων και εκπαιδευτικού υλικού (σχέδια μαθημάτων, φύλλα εργασίας, αρχεία δραστηριοτήτων) με στόχο την κατάκτηση βασικών δεξιοτήτων μέσα στις οποίες συγκαταλέγεται η συναισθηματική νοημοσύνη, και συνακόλουθα η βελτίωση της διδακτικής πράξης. Ακόμα, οι ΨΚΜ παρέχουν ένα μαθησιακό περιβάλλον διάδρασης και αλληλομάθησης, που εμπλέκει ενεργά τους μαθητές στην προσωπική δόμηση της γνώσης, ενώ τα μέλη τους διακρίνονται από μεγάλη θέληση για επικοινωνία και μάθηση (Bostock, 1998; Kim, 2000; Porterfield, 2001; Goodfellow, 2003). Στόχος της παρούσας εργασίας ήταν να αξιολογηθεί ηεπίδραση που ενδεχομένως είχε στην ενίσχυση της συναισθηματικής νοημοσύνης των μαθητών/τριών με μαθησιακές δυσκολίες η συμμετοχή τους σε ΨΚΜ. Τριάντα δυο παιδιά εκ των οποίων τα δεκαέξι είχαν μαθησιακές δυσκολίες συμμετείχαν στο πρόγραμμα που υλοποιήθηκε στα πλαίσια της Ευέλικτης Ζώνης και είχε ως θέμα «Τα δικαιώματα των παιδιών» χρησιμοποιώντας ως περιβάλλον αλληλεπίδρασης ΨΚΜ που αναπτύχθηκαν μέσω της διαδικτυακής υπηρεσίας GmailGroups. Αφορμή στάθηκε η κλιμάκωση του προσφυγικού ζητήματος, που αποτελεί κυρίαρχο μέρος της διεθνούς αλλά και ελληνικής επικαιρότητας. Η ανάπτυξη της συναισθηματικής νοημοσύνης των μαθητών με μαθησιακές δυσκολίες αξιολογήθηκε με συγκεκριμένο ερωτηματολόγιο που δημιουργήθηκε ειδικά γι’ αυτό το σκοπό πριν και μετά τη συμμετοχή των μαθητών στις ΨΚΜ. Από την ανάλυση των δεδομένων προέκυψε ότι η εξ αποστάσεως μάθηση που έλαβε χώρα στις ΨΚΜ ενίσχυσε σημαντικά τη συναισθηματική νοημοσύνη των μαθητών/τριών με μαθησιακές δυσκολίες.
Small Apartments As an Investment Medium in the Housing Market
Authors: Рыжкова  , Ryzhkova M. , Кондратьева  , Kondrateva A. 
Published: December 2016

In the context of economic downturn, Russian households seek to preserve their
savings by investing them on local housing market. The research shows
a decrease in the newly-built apartment’s average size that leads to the suggestion
that apartment purchases on Russian housing market are in many cases
investments by their nature. On the example of the Tomsk primary housing
market, we reveal that small-sized apartments as an investment medium has
sufficiently high quality characteristics which ensures their liquidity. The
availability of investments is guaranteed by reducing the size of an apartment.

Published: December 2016

Nowadays, due to technical and economic reasons, the distributed generation (DG) units are widely connected to the low and medium voltage network and created a new structure called micro-grid. Renewable energies (especially wind and solar) based DGs are one of the most important generations units among DG units. Because of stochastic behavior of these resources, the optimum and safe management and operation of micro-grids has become one of the research priorities for researchers. So, in this study, the optimal operation of a typical micro-grid is investigated in order to maximize the penetration of renewable energy sources with the lowest operation cost with respect to the limitations for the load supply and the distributed generation resources. The understudy micro-grid consists of diesel generator, battery, wind turbines and photovoltaic panels. The objective function comprises of fuel cost, start-up cost, spinning reserve cost, power purchasing cost from the upstream grid and the sales revenue of the power to the upstream grid. In this paper, the uncertainties of demand, wind speed and solar radiation are considered and the optimization will be made by using the GAMS software and mixed integer planning method (MIP).Article History: Received May 21, 2016; Received in revised form July 11, 2016; Accepted October 15, 2016; Available onlineHow to Cite This Article: Jasemi, M., Adabi, F., Mozafari, B., and Salahi, S.

Published: December 2016

Countries like Malaysia have more that 70% of its population living in rural areas. Majority of these rural areas lie in regions where most villages do not have grid connected electricity. Renewable energy using photovoltaic (PV) panels offers an alternative and cost efficient solution that exploits the yearlong abundance of sunlight available in countries like Malaysia. The main problem with PV systems is the high maintenance costs in replacing batteries every few years which makes PV systems unattractive for rural areas. A full scale PV system, developed in Semenyih Malaysia, aims to increase battery lifetime and reduce maintenance costs by incorporating supercapacitors. The system was developed in a life-sized cabin to mimic a rural home. A programmable load is used to test the system with the load profile of a typical rural household usage. Experimental and simulation results show that the supercapacitor bank is able to reduce the stress on the battery by absorbing peak current surges. Results also show that the system is able to maintain a high battery state of charge during the entire day.Article History: Received June 17th 2016; Received in revised form August 16th 2016; Accepted Sept 10th 2016; Available onlineHow to Cite This Article: Fahmi, M.I., Rajkumar, R., Wong, Y.W., Chong, L.W., Arelhi, R., and Isa, D.

AbstractModern communication platforms require a huge amount of switched RF component banks especially made of different filters and antennas to cover all operating frequencies and bandwidth for the targeted services and application scenarios. In contrast, reconfigurable devices made of tunable components lead to a considerable reduction in complexity, size, weight, power consumption, and cost. This paper gives an overview of suitable technologies for tunable microwave components especially for SatCom applications. Special attention is given to tunable components based on functional materials such as barium strontium titanate (BST) and liquid crystal (LC).

Flowering Plants Preferred by Bumblebees (BombusLatr.) in the Botanical Garden of Medicinal Plants in Wrocław
Authors: Sikora Aneta , Michołap Paweł , Kelm Maria 
Published: December 2016

AbstractDue to fewer bumblebees in rural areas these days, it is necessary to look for alternative habitats for the active protection of these very important pollinators. The research was carried out in The Botanical Garden of Medicinal Plants, in Wrocław, Poland. In the garden, approximately 2000 plant species were cultivated, of which 185 were visited by bumblebees. Amongst them, 57 plant species were deemed very attractive and were determined to be indicators for 7 bumblebee species. Indicator species for bumblebees ranged between 6 forBombus pratorumto up to 20 forB. pascuorum.Monarda didymawas an indicator plant to 6 recorded bumblebee species. Other indicator plant species for at least 4 bumblebees species were:Origanum vulgare,Lavandula angustifolia,Rhododendron catawbiense,Phacelia tanacetifolia, andAgastache rugosa. Three bumblebee species were found to forage the most on 11 of the flowering plant species. The biggest group of plants were those which were mostly visited by 1-2 bumblebee species. Amongst all recorded indicator plants, 32% were native species.
Evaluation of Selected Ornamental Asteraceae as a Pollen Source for Urban Bees
Authors: Wróblewska Anna , Stawiarz Ernest , Masierowska Marzena 
Published: December 2016

Abstract
Offering more floral resources for urban bees can be achieved by growing ornamental bee plants. The aim of the present study was to evaluate selected Asteraceae (Calendula officinalis ‘Persimmon Beauty’ and ‘Santana’, Centaurea macrocephala, Cosmos sulphureus, Dahlia pinnata, Tagetes patula, Tithonia rotundifolia, and Zinnia elegans) as pollen sources for pollinators. Under urban conditions in Lublin, SE Poland, the investigated plants flowered from late June to the end of October. The mass of pollen produced in florets and capitula was found to be species-related. The highest pollen amounts per 10 florets (10.1 mg) as well as per capitulum (249.7 mg) were found for C. macrocephala. The mass of pollen yielded by a single plant depended on both the pollen mass delivered per disk florets and the proportion of disk florets in capitulum, and the flowering abundance of the plants. A single plant of D. pinnata and a single plant of T. rotundifolia each produced the largest pollen mass. Mean pollen yield per 1m2 of a plot ranged from 6.2 g (Z. elegans) to 60.7 g (D. pinnata). Pollen grains are tricolporate, with echinate exine, medium or small in size. They can be categorised as oblatespherical, spherical, and prolatespherical. The principal visitors to C. macrocephala, C. sulphureus, and C. officinalis were honey bees, whereas bumble bees dominated on T. rotundifolia and D. pinnata. A magnet plant for butterflies was Z. elegans. Among the investigated species, D. pinnata, C. macrocephala, and T. rotundifolia were found to be the most valuable sources of pollen flow for managed and wild bees.

AbstractWe investigated the rearing of drone larvae grafted in queen cells. From the 1200 drone larvae that were grafted during spring and autumn, 875 were accepted (72.9%) and reared as queens. Drone larvae in false queen cells received royal jelly of the same composition and of the same amounts as queen larvae. Workers capped the queen cells as if they were drones, 9-10 days after the egg laying. Out of 60 accepted false queen cells, 21 (35%) were capped. The shape of false queen cells with drone larvae is unusually long with a characteristically elongate tip which is probably due to the falling of larvae. Bees start the destruction of the cells when the larvae were 3 days old and maximised it before and after capping. Protecting false queen cells in the colony by wrapping, reversing them upside down, or placing in a horizontal position, did not help. The only adult drones that emerged from the false queen cells were those protected in an incubator and in push-in cages. Adult drones from false queen cells had smaller wings, legs, and proboscis than regular drones. The results of this study verify previous reports that the bees do not recognise the different sex of the larvae at least at the early stage of larval development. The late destruction of false queen cells, the similarity in quality and quantity of the produced royal jelly, and the bigger drone cells, allow for the use of drone larvae in cups for the production of royal jelly.

Published: December 2016

Abstract
The aim of this work is an analysis of some geometrical inverse problems related to the identification of cavities in linear elasticity framework. We rephrase the inverse problem into a shape optimization one using an energetic least-squares functional. The shape derivative of this cost functional is combined with the level set method in a steepest descent algorithm to solve the shape optimization problem. The efficiency of this approach is illustrated by several numerical results.

Robust dynamic output feedback fault-tolerant control for Takagi-Sugeno fuzzy systems with interval time-varying delay via improved delay partitioning approach
Authors: Sun Chao , Wang Fuli , He Xiqin 
Published: December 2016

Abstract
This paper addresses the problem of robust fault-tolerant control design scheme for a class of Takagi-Sugeno fuzzy systems subject to interval time-varying delay and external disturbances. First, by using improved delay partitioning approach, a novel n-steps iterative learning fault estimation observer under H
∞ constraint is constructed to achieve estimation of actuator fault. Then, based on the online estimation information, a fuzzy dynamic output feedback fault-tolerant controller considered interval time delay is designed to compensate for the impact of actuator faults, while guaranteing that the closed-loop system is asymptotically stable with the prescribed H
∞ performance. Moreover, all the obtained less conservative sufficient conditions for the existence of fault estimation observer and fault-tolerant controller are formulated in terms of linear matrix inequalities. Finally, the numerical examples and simulation results are presented to show the effectiveness and merits of the proposed methods.
UV Radiation Detection Using Optical Sensor Based on Eu3+ Doped PMMA
Authors: Miluski Piotr , Kochanowicz Marcin , Żmojda Jacek , Dorosz Dominik 
Published: December 2016

AbstractProgress in UV treatment applications requires new compact and sensor constructions. In the paper a hybrid (organic-inorganic) rare-earth-based polymeric UV sensor construction is proposed. The efficient luminescence of poly(methyl) methacrylate (PMMA) matrix doped by europium was used for testing the optical sensor (optrode) construction. The europium complex assures effective luminescence in the visible range with well determined multi-peak spectrum emission enabling construction of the optrode. The fabricated UV optical fibre sensor was used for determination of Nd:YAG laser intensity measurements at the third harmonic (355 nm) in the radiation power range 5.0-34.0 mW. The multi-peak luminescence spectrum was used for optimization of the measurement formula. The composition of luminescent peak intensity enables to increase the slope of sensitivity up to −2.8 mW-1. The obtained results and advantages of the optical fibre construction enable to apply it in numerous UV detection systems.
On Rapid Re-Design of UWB Antennas with Respect to Substrate Permittivity
Authors: Koziel Slawomir , Bekasiewicz Adrian 
Published: December 2016

AbstractRe-design of a given antenna structure for various substrates is a practically important issue yet non trivial, particularly for wideband and ultra-wideband antennas. In this work, a technique for expedited redesign of ultra-wideband antennas for various substrates is presented. The proposed approach is based on inverse surrogate modeling with the scaling model constructed for several reference designs that are optimized for selected values of the substrate permittivity. The surrogate is set up at the level of coarse-discretization EM simulation model of the antenna and, subsequently, corrected to provide prediction at the high-fidelity EM model level. The dimensions of the antenna scaled to any substrate permittivity within the region of validity of the surrogate are obtained instantly, without any additional EM simulation necessary. The proposed approach is demonstrated using an ultra-wideband monopole with the permittivity scaling range from 2.2 to 4.5. Numerical validation is supported by physical measurements of the fabricated prototypes of the re-designed antennas.

Published: December 2016

Abstract
The diet of the Eurasian eagle owl (Bubo bubo) was studied in Wadi Al Makhrour, Bethlehem, Palestinian Territories in 2015 with fresh and several year old pellets. Three species of arthropods, one reptile species, at least four bird species, and six species of mammals were recovered from the studied pellets. Black rat (Rattus rattus) was the most common prey (37.0%), followed by the southern white-breasted hedgehog (Erinaceus concolor) (29.4%) and birds (21.8%). Comparison of recent and older pellets showed change in diet composition. Recent pellets contained more Rattus rattus compared to older ones. Older pellets included more naturally-occurring species such as Meriones tristrami, Microtus guentheri, and Rousettus aegyptiacus, which were absent in newer pellets.
Factors influencing the movements during the breeding season of a female booted eagle (Aquila pennata) tagged by satellite in central Catalonia (Spain)
Authors: Bosch Josep , Calvo José Francisco , Bermejo Ana , Puente Javier de la 
Published: December 2016

Abstract
Foraging movements during the breeding season are a poorly studied aspect of booted eagle behaviour. We have investigated the relationship between weather and other abiotic factors and foraging behaviour, and also resource use by a female booted eagle, tagged by satellite-GPS transmitter in central Catalonia, during summer 2012 and spring 2013. Generalized Linear Models (GLMs) revealed that the distance travelled from the nest was significantly related to temperature, but also to the time of day and the age of chicks. Temperature also had a significant positive influence on flight altitude and the latter on flight speed. The Resource Utilization Function (RUF) showed significant resource use in locations close to water (rivers and water bodies) and also in agricultural areas, preferably close to urban areas and rivers. On the other hand, unlike in other areas of Spain, the use of the edges between forest and agricultural areas and forest areas themselves showed negative coefficients with values not significant, perhaps related to changes in prey availability in the traditional hunting grounds.
Diluted Blood: Identity and the Other in Three Novels by Doeschka Meijsing
Authors: Lammer Christina 
Published: December 2016

Abstract
Two hypotheses on identity lay at the core of this paper. (1) Doeschka Meijsing presents identity as unstable and as a construct of one’s own in three novels. (2) Meijsing uses memory discourses and cultural phenomena to display how characters struggle when (re-)constructing their identities. Pip (Over de liefde, 2008), has to deal with the secret affair of her female lover who has got pregnant. She refuses to be the ‘left one’ everyone feels pity for. As a result, she has to create a new identity that doesn’t fit the expectations of others. In 100% Chemie (2002), an unnamed daughter of a German migrant and Dutch father grew up in the Netherlands. As she doesn’t identify with any nationality she seeks to stabilize her fragmented identity. Investigating the history of her German family she tries to create her own identity. Robert Martin, main character of De tweede man (2000), struggles with the legacy of his brother Alexander who has passed away. Robert has not only inherited his brother’s fortune but also his friends. They want Robert to replace Alexander. Robert has to create a new identity which fits their lifestyle. Meijsing’s characters feel as if they have ‘lost’ their identities, as far as they ‘owned’ ones. As a result, their stories stress views on identity: do they have fixed identities, which can be destroyed? Is identity a construction and if so, how can it be created? I discuss how cultural memory, especially counter-memory which questions memory discourses, impacts the construction of identity. Furthermore, I show how intersections of identity categories trouble Meijsing’s characters.
