Υποστηρίζοντας τις οπτικές των παιδιών στο ελεύθερο παιχνίδι: μια εκπαιδευτική παρέμβαση
Authors: Tanakidou Maria , Avgitidou Sofia
Published: December 2016

Η παρούσα έρευνα έχει ως αντικείμενο τη μελέτη μιας εκπαιδευτικής παρέμβασης με στόχο τη συμμετοχή των παιδιών στην έρευνα και στη λήψη αποφάσεων σχετικά με το ελεύθερο παιχνίδι στο νηπιαγωγείο. Σκοπός της παρούσας έρευνας ήταν η διερεύνηση των οπτικών των παιδιών για τον χώρο του ελεύθερου παιχνιδιού μέσω της συλλογής πληροφοριών από τα ίδια, η περιγραφή των αλληλεπιδράσεων των παιδιών κατά τη διαδικασία σχεδιασμού και λήψης αποφάσεων για την αλλαγή του χώρου και η διερεύνηση των τρόπων υποστήριξης της συμμετοχής των παιδιών στην έκφραση ιδεών, στον σχεδιασμό και στην υλοποίηση της αλλαγής του χώρου. Συμμετέχοντες στην έρευνα αποτέλεσαν 11 παιδιά μιας τάξης νηπιαγωγείου, ηλικίας 5-6 ετών. Η έρευνα αποτελεί μελέτη περίπτωσης και η μέθοδος ανάλυσης είναι θεματική. Οι τεχνικές που χρησιμοποιήθηκαν για την ανάδειξη των οπτικών των παιδιών ήταν αυτές της μεθόδου μωσαϊκού: ξενάγηση στο χώρο από τα παιδιά, φωτογραφίες του χώρου από τα παιδιά και σχολιασμός τους, ενώ τα υπόλοιπα εργαλεία συλλογής των ερευνητικών δεδομένων ήταν το ημερολόγιο της ερευνήτριας, η βιντεοσκόπηση και οι αναστοχαστικές συζητήσεις με την κριτική φίλη. Τα αποτελέσματα αποτυπώνουν ενδιαφέρουσες όψεις των οπτικών των παιδιών, των στρατηγικών της ερευνήτριας για την ενίσχυση των παιδιών ως ερευνητών και δρώντων προσώπων στη λήψη και υλοποίηση των προτάσεών τους, καθώς των μορφών αλληλεπίδρασης των παιδιών κατά τη διαδικασία συναπόφασης και δράσης. Τα συμπεράσματα αναδεικνύουν τις διαφορετικές οπτικές ενηλίκων και παιδιών για το παιχνίδι, τις προκλήσεις μιας αυθεντικής διαδικασίας συμμετοχής των παιδιών στην έρευνα και τη λήψη αποφάσεων και τη δυναμική εικόνα του παιδιού της προσχολικής ηλικίας.

Η εξ αποστάσεως εκπαίδευση (εξΑΕ) είναι μία μέθοδος που εφαρμόζεται σε όλες τις βαθμίδες εκπαίδευσης. Τα ερευνητικά δεδομένα, ωστόσο, που υπάρχουν για την εφαρμογή της σε παιδιά νηπιακής ηλικίας είναι ελάχιστα. Η παρούσα εργασία στοχεύει στο να διερευνηθούν οι δυνατότητες που προσφέρει η εξΑΕ στον εμπλουτισμό της μαθησιακής εμπειρίας των παιδιών νηπιακής ηλικίας, μέσα από ένα παράδειγμα συμπληρωματικής μουσειακής εξ αποστάσεως εκπαίδευσης με τη συμβολή της τεχνολογίας. Για τις ανάγκες της εργασίας διενεργήθηκε έρευνα δράσης στην οποία συμμετείχαν δεκαεπτά νήπια ολοήμερου τμήματος νηπιαγωγείου καθώς και η εκπαιδευτικός-ερευνήτρια. Για τη συλλογή πληροφοριών χρησιμοποιήθηκε η μέθοδος της δομημένης συνέντευξης με χρήση ερωτηματολογίου καθώς και η μη δομημένη παρατήρηση των νηπίων σε όλη τη διάρκεια της παρέμβασης. Η εφαρμογή μουσειακής αγωγής από απόσταση συνέβαλλε στο να αποκτήσουν τα παιδιά γνώσεις και όχι απλά να αποκομίσουν εντυπώσεις και ενθουσιασμό. Συνεπώς, οι πρώτες πληροφορίες για την εφαρμογή συμπληρωματικής εξ αποστάσεως μουσειακής εκπαίδευσης σε σχέση με τον εμπλουτισμό της μαθησιακής εμπειρίας των νηπίων αποτιμώνται ως θετικές. Το γεγονός αυτό φανερώνει ότι η από απόσταση εκπαίδευση είναι δυνατόν να εφαρμοστεί με επιτυχία και σε αυτή την ηλικία. Σίγουρα ασφαλέστερα επιστημονικά συμπεράσματα για την εφαρμογή της θα προκύψουν από την επανάληψη αυτής ή παρόμοιας έρευνας με μεγαλύτερο δείγμα νηπίων. Η εργασία αυτή ωστόσο ανοίγει νέες προοπτικές για την εξ αποστάσεως εκπαίδευση στη νηπιακή ηλικία και παράλληλα δίνει το ερέθισμα να διερευνηθούν άλλες παράμετροι, όπως το εκπαιδευτικό υλικό και ο ρόλος του/της νηπιαγωγού στη μέθοδο της από απόσταση εκπαίδευσης των νηπίων.

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.
ultraLM and miniLM: Locator tools for smart tracking of fluorescent cells in correlative light and electron microscopy

Published: December 2016

In-resin fluorescence (IRF) protocols preserve fluorescent proteins in resin-embedded cells and tissues for correlative light and electron microscopy, aiding interpretation of macromolecular function within the complex cellular landscape. Dual-contrast IRF samples can be imaged in separate fluorescence and electron microscopes, or in dual-modality integrated microscopes for high resolution correlation of fluorophore to organelle. IRF samples also offer a unique opportunity to automate correlative imaging workflows. Here we present two new locator tools for finding and following fluorescent cells in IRF blocks, enabling future automation of correlative imaging. The ultraLM is a fluorescence microscope that integrates with an ultramicrotome, which enables ‘smart collection’ of ultrathin sections containing fluorescent cells or tissues for subsequent transmission electron microscopy or array tomography. The miniLM is a fluorescence microscope that integrates with serial block face scanning electron microscopes, which enables ‘smart tracking’ of fluorescent structures during automated serial electron image acquisition from large cell and tissue volumes.

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.
Locally recurrent rectal cancer: the nursing role pre-treatment
Authors: Taylor Claire
Published: December 2016

Treatment options for individuals with locally recurrent rectal cancers have improved considerably over the past 10 years. However, deciding on the best management approach can be complicated, as multimodality regimens are often used, while surgery, when proposed, may well involve a radical and complex resection, which may not be suitable. A multidisciplinary team approach is an essential requirement in the management of locally recurrent rectal cancers, and the clinical nurse specialist (CNS) is an integral part of this team, helping patients navigate the health-care system, understand the treatment options available and cope with any associated concerns and symptoms. The invaluable role that CNSs often play in the care of these patients needs wider acknowledgement and further articulation.
Information for Patients and Carers
Authors: Dale J.J. , Gibson B.
Published: December 2016

It Is essential for nurses to develop their skills in the education of patients with leg ulcers. No ulcer will be healed, or prevented, unless the patient co-operates with, and participates in, the treatment. Full compliance is more likely if the patient understands what is being done, and why. Teaching patients the self-help skills which they should practise for the rest of their lives to promote healing and prevent ulcer recurrence requires patience, skill and an understanding of the individual's personal circumstances1.
Investigations for Assessment
Authors: Vowden K.R. , Vowden R
Published: December 2016

One of the most important aspects of leg ulcer management is to establish the causal pathology. Unless the correct diagnosis is established treatment is, at best, likely to be unsuccessful but could be harmful1. For example, inappropriate use of compression bandaging can cause significant skin necrosis1,2. Equally, failure to use adequate compression when treating venous ulceration has been shown to delay healing3 significantly. It is therefore important that the patient is fully assessed and a structured history obtained4,5. This should determine which investigations will be required.
Compression Bandaging: Selection and Evidence
Authors: Nelson E.A. , Moffatt C.
Published: December 2016

The use of effective compression has been shown to heal venous leg ulcers1and prevent their recurrence2whereas inappropriate compression may lead to skin damage and, in extreme cases, amputation3. It is therefore important to differentiate between appropriate and inappropriate compression. Compression is palliative rather than curative, and hence needs to be worn for as long as the patient's venous disease is present: in most cases this means a lifetime. Compression should be applied only after a clinician with appropriate training has excluded the possibility of arterial disease.
Multidisciplinary Care of the Diabetic Foot
Authors: Foster A.V.M.
Published: December 2016

Patients with diabetes account for about 1–2% of the general population, and will undergo around half of all major leg amputations. Despite this fact, there are no traditional pathways for the referral and treatment of diabetic foot disease. Physicians may view it as a surgical problem, while surgeons may see it as a diabetic complication. All too often, patients are seen as undesirable cases who take up much-needed hospital beds. Until the 1980s, morbidity and mortality associated with diabetic foot problems were unacceptably high and no effective preventive or treatment strategies were known. Health-care professionals managing foot problems in patients with diabetes tended to work in isolation and diabetic foot disease was often neglected or treated inappropriately.
Pathology of the Diabetic Foot

All Quiet on the Western Front: The Outcome of Israel's March 2015 Elections and the Peace Process
Authors: A. Murat Agdemir
Published: December 2016

The March 17, 2015 parliamentary elections were held roughly two years after the previous elections. According to the results, the incumbent Prime Minister Benjamin Netanyahu has formed the new government. It controls 61 parliamentary seats, and is a narrow, right-wing and ultra-Orthodox government with the narrowest of Knesset majorities. Its composition shows that it would be one of the most right-wing administrations in Israel's history, and there is hardly a mention or plan of resolving the Palestinian conflict. This article tries to analyze whether the electoral results open up new possibilities for the peace process and Israel's security agenda.

El sesgo mediocéntrico del "framing" en España: una revisión crítica de la aplicación de la teoría del encuadre en los estudios de comunicación
Authors: Valera Ordaz Lidia
Published: December 2016

En este artículo se propone una revisión crítica de los enfoques teóricos metodológicos predominantes en la literatura sobre framing en España. Su propósito es señalar que existe un sesgo mediocéntrico, pues los estudios tienden a tomar los encuadres periodísticos como variable independiente, pero no suelen abordan el proceso dinámico y conflictivo de su producción y negociación. Este sesgo responde a una concepción de los marcos como resultado de las rutinas periodísticas, lo que implica desatender las múltiples influencias políticas, socialese ideológicas que subyacen a la producción de los marcos periodísticos.
Sor Lekutik Avignonera “bultzi leiotik”, Euskarazko zinemaren hastapenen bidaia
Authors: Martinez Josu
Published: December 2016

André Madré y Gotzon Elortza son los dos primeros autores de la historia del cine en euskara. Los dos rodaron casi al mismo tiempo, los dos vivían en Paris y los dos realizaron documentales amateurs: El primero, el largometraje “Gure Sor Lekua” (1956); el segundo, los cortos “Ereagatik Matxitxakora” (1959), “Elburua Gernika” (1960), “Aberria” (1961) y “Avignon” (1963). Sin embargo, son dos cineastas completamente diferentes biográfica, social e ideológicamente, y representan la evolución y el cambio de ciclo que vivió la cultura euskaldun en la década de los 50. Con un análisis histórico de sus trabajos y de las motivaciones de cada uno, este artículo contextualiza la labor de Madré y Elorza en un momento clave para la modernización del euskera, y trata de explicar los profundoscambios que se dieron en la cultura.

Figurilla femenina embarazada con símbolo astral en la antigua Caura: ¿súplica privada a Dea Caelestis?
Authors: Oria Segura Mercedes , Escacena Carrasco José Luis
Published: December 2016

Estudiamos en este artículo una pequeña terracota procedente de la antigua ciudad de Caura, hoy Coria del Río (provincia de Sevilla). Aunque no se conserva completa, representa una figura femenina en estado de gestación. La imagen se apoya sobre una base troncocónica hueca que exhibe en su parte delantera un símbolo astral. Es posible que dispusiera inicialmente de brazos abiertos en actitud orante. Estos rasgos sugieren interpretar la figurilla como ofrenda o exvoto (¿a Dea Caelestis?), y en cualquier caso como producto de un acto piadoso para propiciar la maternidad. La pieza puede fecharse, sin mayor precisión de momento, en época romana. La dispersión del tipo refleja un importante arraigo en zonas con un marcado sustrato púnico.

Published: December 2016

En este artículo se presenta la investigación que se está llevando a cabo sobre las pinturas murales de la Sala del Mosaico de los Amores en el Conjunto Arqueológico de Castulo, en Linares (Jaén). Durante la campaña efectuada en el año 2011, se descubrió una estancia que albergaba una decoración musivaria y parietal de gran calidad datada en el s. I-II d.C. Parte de esa decoración parietal, concretamente la correspondiente al muro oeste, fue encontrada derrumbada sobre el pavimento, y trasladada a los laboratorios de la Universidad de Granada para su intervención de consolidación y restauración. Dado que apenas existía información sobre pintura mural en Castulo, se está realizando un estudio de las pinturas, en el que se está llevando a cabo la caracterización de materiales y de su técnica de ejecución, como paso previo a su restauración. Estos análisis han permitido identificar una capa pictórica muy rica, constituida por tonos verdes, rojos, ocres, blancos y negros, entre los que destacan pigmentos de gran calidad como el azul egipcio, además de otros que normalmente se encuentran en la paleta romana como el minio, la tierra roja, el negro de hueso o el blanco de cal.
Subsurface Structure and Fluid Flow Analysis Using Geophysical Methods in the Geothermal Manifestation Area of Paguyangan, Brebes, Central Java

Published: December 2016

The indication of an active geothermal system is shown by the presence of surface manifestations such as the hot spring in Kedungoleng, Paguyangan, Brebes, Central Java. The temperature of the largest hot spring reaches 74o C and there is an assumption that this is an outflow of Mount Slamet geothermal system. DC-resistivity, Spontaneous Potential (SP) and Shallow Surface Temperature surveys were conducted to determine the subsurface structure as well as its correlation with the distribution of thermal fluid flow and shallow surface temperature. The subsurface resistivity has been investigated using 5 points of the Schlumberger configuration with 400 m separation for each point. For the fluid and temperature pattern, a measurement using 15 m interval in 3 lines of conducting fixed electrode configuration has been carried out, along with a 75 cm of depth of temperature measurement around the manifestation area. The thermal fluid is assumed by the low resistivity of 0.756 to 6.91Ωm and this indicates sandstone that has permeable characteristic. The fluid flows in two layers of Sandstone at more than 10 meter from surface of the first layer. Accordingly, the SP values have a range between -11- 11 mV and a depth interval of 13.42- 28.75 m and the distribution of temperature is between 24o-70oC at a tilting range of 46.06o-12.60o. Hence it can be inferred that the thermal fluid moves in the Northwest direction and is controlled by a fault structure stretching from Northwest to Southeast.Article History: Received Feb 3, 2016; Received in revised form July 11, 2016; Accepted August 13, 2016; Available onlineHow to Cite This Article: Setyawan, A., Triahadini, A., Yuliananto, Y., Aribowo, Y., and Widiarso, D.A.

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.

How Well Does Consumer-Based Brand Equity Align with Sales-Based Brand Equity and Marketing-Mix Response?
Authors: Datta Hannes , Ailawadi Kusum L. , van Heerde Harald J.
Published: December 2016

Brand equity is the differential preference and response to marketing effort that a product obtains because of its brand identification. Brand equity can be measured using either consumer perceptions or sales. Consumer-based brand equity (CBBE) measures what consumers think and feel about the brand, whereas sales-based brand equity (SBBE) is the brand intercept in a choice or market share model. This article studies the extent to which CBBE manifests itself in SBBE and marketing-mix response using ten years of IRI scanner and Brand Asset Valuator data for 290 brands spanning 25 packaged good categories. The authors uncover a fairly strong positive association of SBBE with three dimensions of CBBE—relevance, esteem, and knowledge—but a slight negative correspondence with the fourth dimension, energized differentiation. They also reveal new insights on the category characteristics that moderate the CBBE–SBBE relationship and document a more nuanced association of the CBBE dimensions with response to the major marketing-mix variables than heretofore assumed. The authors discuss implications for academic researchers who predict and test the impact of brand equity, for market researchers who measure it, and for marketers who want to translate their brand equity into marketplace success.
Development of relative body mass (BMI) of students from Łódź, depending on the selected environmental, psychological and sociological factors
Authors: Pruszkowska-Przybylska Paulina , Skowyra Katarzyna , Sękowski Piotr
Published: December 2016

The human height-to-weight ratio is an important parameter of the body homeostasis. Currently, the most popular measurement determining the relationship between body mass and height is the Quetelet II indicator, called Body Mass Index (BMI). The aim of this study is an evaluation of the differences in the height-to-weight ratios, depending on selected environmental, psychological and sociological factors in people studying at higher education institutions in Łódź. The research was conducted among students of higher education institutions in Łódź, by electronic means or with the use of an anonymous survey. It consisted of 28 closed single or multiple choice questions. Statistical analysis was made of complete results of the research involving 135 people, both males and females, aged between 19-26. It was revealed that the factors related to higher BMI values in students are the following: the presence of a tendency in the students to gain weight themselves, and a tendency to gain weight present in their mothers, an evaluation of their own body mass as excessive, regularly smoking cigarettes and rarely undergoing medical check-ups. Among the factors connected with lower BMI values are: regular coffee consumption, perception of their own body mass as being too low, and also obtaining systolic pressure values below 110 mm Hg. Additionally, a positive correlation between taking up physical activity and higher values of systolic blood pressure (p<0.05) was shown. Among the subjects, it was found that 92% of the underweight women declared that their body mass and figure were normal. In the case of women with optimal BMI values, 40% stated that their body mass was excessive. In the case of men the problem was reverse: 50% of the subjects who were either overweight or obese claimed that their body mass was within the norm. The factors that significantly influence body proportion differences among students include the subject’s and the subject’s mother’s tendency to put on weight, self-evaluation of their own body mass, the values of systolic blood pressure, coffee consumption and cigarette smoking, as well as the frequency of medical check-ups.

Modern 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

Due 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

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.

We 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.
An energy gap functional: Cavity identification in linear elasticity
Authors: Ben Abda Amel , Jaïem Emna , Khalfallah Sinda , Zine Abdelmalek
Published: December 2016

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.

h = 0. In this paper, we prove that the curvature tensor of M

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

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

Progress 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

Re-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.

A generalization of a result of Berezin and Gel’fand in the context of Eaton triples is given. The
generalization and its proof are Lie-theoretic free and requires some basic knowledge of nonsmooth analysis.
The result is then applied to determine the distance between a point and a G-orbit or its convex hull.We also
discuss the derivatives of some orbital functions.
Change in diet of the Eurasian eagle owl (Bubo bubo) suggests decline in biodiversity in Wadi Al Makhrour, Bethlehem Governorate, Palestinian Territories
Authors: Amr Zuhair S. , Handal Elias N. , Bibi Faysal , Najajrah Mohammad H. , Qumsiyeh Mazin B.
Published: December 2016

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

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

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.
