description: Αυτή η έρευνα έγινε στην περιοχή του Κ Νευροκοπίου Δράμας και αφορά την καλλιέργεια της πατάτας η οποία φέρει Ονομασία Γεωγραφικής Ένδειξης.Παρουσιάζεται η τεχνική της καλλιέργειας κατά φάση και οικονομικά στοιχεία. .Η ερευνά έγινε με χρήση ερωτηματολογίου σε δείγμα 129 παραγωγών με προσωπική συνέντευξη. Στόχος ήταν ο προσδιορισμός του κόστους παραγωγής και η προβολή του μεγάλου προβλήματος που αντιμετωπίζουν οι παραγωγοί της περιοχής Νευροκοπίου με το υψηλό κόστος, αλλά και η μεθοδολογία με την οποία μπορούν με σωστές επιλογές να μειώσουν το κόστος παραγωγής και να αυξήσουν τα έσοδα τους. Η πατάτα αποτελεί μονοκαλλιέργεια για την περιοχή, και δεν έχει υλοποιηθεί προηγουμένη έρευνα. Ερευνήθηκε μέσα από την περιγραφική ανάλυση ο χρόνος και οι δαπάνες για κάθε είδος καλλιεργητικής εργασίας συναρτήσει με τις κλάσεις έκτασης αλλά και συναρτήσει με τις κλάσεις απόδοσης. Γενικά διαπιστώθηκε ότι οι παραγωγοί του δείγματος μπορούν να μειώσουν το κόστος παραγωγής. Προέκυψαν προτάσεις για τον τρόπο που θα μειωθεί το κόστος και επιβεβαιώθηκε η σπουδαιότητα του ανθρώπινου παράγοντα στην σωστή και αποτελεσματική διαχείριση των συντελεστών παραγωγής.
description: The research has been conducted in the region of Kato Nevrokopi of the Prefercture of Drama in Greece and concerns the cultivation of potatoes signed as Products of Geographic Indication (PGI). We present the techniques of cultivation at each stage and economical elements. The research has been based on questionnaires addressed to a sample of 129 producers by the method of interviews. The aim was the determination of production cost and the emergence of the problems related with the high cost of production as far as the methodology allowing them to reduce the production cost and increase their incomes. The cultivation of potatoes is single-crop farming for the region and no previous research has been done about this subject. The descriptive analysis was oriented to the research of parameters such as time and cost for each stage of cultivation as dependence of the extend of fields as far as of the productivity. A general conclusion extracted form the sample is the possibility to reduce the cost of production. Proposals also resulted about the reduction of cost confirm the importance of human factor to a sound and effective administration of production factors.

description: Η παρούσα εργασία εξετάζει την εικονογραφία των τεσσάρων βασικότερων ελευσινιακών θεοτήτων (Δήμητρα, Περσεφόνη, Τριπτόλεμος, Πλούτων) σε αγγειογραφίες της Αττικής και της Μ. Ελλάδας κατά τον 5ο και 4ο αι.π.Χ. Σκοπός της εργασίας είναι ύστερα από μια αναλυτική παρουσίαση των μορφών των θεοτήτων αυτών στα αγγεία των προαναφερθέντων εργαστηρίων να καταλήξει σε ομοιότητες και διαφορές ανάμεσα σε αυτά. Η σύγκριση οδηγεί σε συμπεράσματα ότι οι διαφορές πηγάζουν κυρίως από αλλαγές στο μύθο και τη λατρεία των επονομαζόμενων ελευσινιακών θεοτήτων στις δυο περιοχές (Αττική-Μεγ. Ελλάδα) στις οποίες ανήκουν τα δύο εργαστήρια. Επιπλέον, διαφοροποιήσεις στην αγγειογραφία αποδίδονται και στις αλλαγές που συντελούνται στο πολιτικό και ιστορικό σκηνικό της Αθήνας και συνολικά της Ελλάδας από το τέλος του 6ου αρχές 5ου αι. π.Χ. ως το τέλος του 4ου αι. π.Χ.
description: Eleusinian iconography is widely expressed through the scenes of the black-figured and especially red-figured Athenian vases. the four main eleusinian deities are also popular in South-Italian representations. Between these two great workshops of antiquity there are similarities but also differences, which mostly derive from changes in worship and myth. Nevertheless, changes in the Eleusinian iconography can also be attributed to the political and historical setting of Athens and Greece in general from the end of 6th beginning of 5th to the end of the 4th century B.C.

description: At the time of defining the science objectives of the INTernational Gamma-Ray Astrophysics Laboratory (INTEGRAL), such a rapid and spectacular development of multi-messenger astronomy could not have been predicted, with new impulsive phenomena becoming accessible through different channels. Neutrino telescopes have routinely detected energetic neutrino events coming from unknown cosmic sources since 2013. Gravitational wave detectors opened a novel window on the sky in 2015 with the detection of the merging of two black holes and in 2017 with the merging of two neutron stars, followed by signals in the full electromagnetic range. Finally, since 2007, radio telescopes detected extremely intense and short burst of radio waves, known as Fast Radio Bursts (FRBs) whose origin is for most cases extragalactic, but enigmatic. The exceptionally robust and versatile design of the INTEGRAL mission has allowed researchers to exploit data collected not only with the pointed instruments, but also with the active cosmic-ray shields of the main instruments to detect impulses of gamma-rays in coincidence with unpredictable phenomena. The full-sky coverage, mostly unocculted by the Earth, the large effective area, the stable background, and the high duty cycle (85%) put INTEGRAL in a privileged position to give a major contribution to multi-messenger astronomy. In this review, we describe how INTEGRAL has provided upper limits on the gamma-ray emission from black-hole binary mergers, detected a short gamma-ray burst in coincidence with a binary neutron star merger, contributed to define the spectral energy distribution of a blazar associated with a neutrino event, set upper limits on impulsive and steady gamma-ray emission from cosmological FRBs, and detected a magnetar flare associated with fast radio bursting emission.

description: This paper introduces the methodology proposed by our group to model the biological soft tissues deformations and to couple these models with Computer-Assisted Surgical (CAS) applications. After designing CAS protocols that mainly focused on bony structures, the Computer Aided Medical Imaging group of Laboratory TIMC (CNRS, France) now tries to take into account the behaviour of soft tissues in the CAS context. For this, a methodology, originally published under the name of the Mesh-Matching method, has been proposed to elaborate patient specific models. Starting from an elaborate manually-built "generic" Finite Element (FE) model of a given anatomical structure, models adapted to the geometries of each new patient ("patient specific" FE models) are automatically generated through a non-linear elastic registration algorithm. This paper presents the general methodology of the Mesh-Matching method and illustrates this process with two clinical applications, namely the orbital and the maxillofacial computer-assisted surgeries.

description: Pressure ulcers are recognized as a major health issue in individuals with spinal cord injuries and new approaches to prevent this pathology are necessary. An innovative health strategy is being developed through the use of computer and sensory substitution via the tongue in order to compensate for the sensory loss in the buttock area for individuals with paraplegia. This sensory compensation will enable individuals with spinal cord injuries to be aware of a localized excess of pressure at the skin/seat interface and, consequently, will enable them to prevent the formation of pressure ulcers by relieving the cutaneous area of suffering. This work reports an initial evaluation of this approach and the feasibility of creating an adapted behavior, with a change in pressure as a response to electro-stimulated information on the tongue. Obtained during a clinical study in 10 healthy seated subjects, the first results are encouraging, with 92% success in 100 performed tests. These results, which have to be completed and validated in the paraplegic population, may lead to a new approach to education in health to prevent the formation of pressure ulcers within this population.

description: Cookie disclaimers are these days an indispensable part of surfing and working on the Internet. In this work, we report on examining and classifying the cookie disclaimers on the 500 most popular websites in Germany, based on the presented information about data collection via cookies and the provided choices at the cookie disclaimer. Our analysis results in 13 categories of cookie disclaimers, consisting of six main categories and additional subcategories. Our findings include that dark pattern based categories were prevalent among the cookie disclaimers: e.g. (1) more than 85\% of the investigated websites providing a cookie disclaimer and giving the option to reject cookies are visually nudging users towards accepting all cookies; (2) Only 21.5\% of those providing a cookie disclaimer offer a reject-all option with a single click. We discuss our results and conclude that both raising user awareness as well as addressing dark patterns from a legal point of view is needed.

description: We study an impurity immersed in the mixture of Bose ultracold gases in the regime where a quantum droplet exists. The quasi-one-dimensional geometry is considered. We find an effective attractive potential that acts by the quantum droplet onto the impurity. The bound states of the impurity in this potential are investigated. These impurity bound states can provide potential probes for the presence of quantum fluctuations effects on the droplet properties. In the case of strong impurity-BEC coupling, we study the properties of the nonlinear local modes on the impurity induced by the quantum fluctuations.

description: As brincadeiras estão presentes no dia a dia de cada criança, cada uma interagindo do seu jeito e maneira, sendo assim a aplicação de atividades que realçam as habilidades motoras tornam-se mais fácil para os professores de educação física, pois através do lúdico a criança se diverte com a brincadeira e ao mesmo tempo realça suas habilidades motoras. Na faixa etária infantil os alunos muitas vezes preferem as brincadeiras ao invés das atividades esportivas, pois as mesmas exigem regras que nem sempre são compreendidas pelas crianças, é nessa faixa etária também que as habilidades motoras estão sendo lapidadas, por isso é fundamental que o exercício físico seja trabalhado de uma forma correta para que não haja nenhum erro irreversível futuramente. A partir do momento que se aplica uma brincadeira, de imediato, as habilidades motoras começam a ser trabalhadas, sejam elas capacidade de resistência, força (levantar, saltar), velocidade, flexibilidade e agilidade. Através do mesmo pode-se criar uma referência para que os professores possam aguçar seus conhecimentos sobre as brincadeiras que serão aplicadas por eles. A pesquisa de campo será um instrumento muito importante, pois o propósito do mesmo será questionar quatro professores de educação infantil sendo que dois atuam na Creche Municipal Alvorada e os outros dois na Creche Municipal São Francisco De Asis, sendo que o intuito da pesquisa será investigar os fatos no meio em que são aplicados.

Οι καρποί που χρησιμοποιήθηκαν βρίσκονταν στο στάδιο συγκομιδής για κατανάλωση. Οι μετρήσεις που έγιναν αφορούσαν το νωπό και ξηρό βάρος του καρπού και των σπόρων (g), το μήκος, την διάμετρο και το πάχος της σάρκας του καρπού (cm), το χρώμα της κάθε ποικιλίας, τις συγκεντρώσεις των διαλυτών στερεών, της ολικής οξύτητας (% κιτρικό οξύ), του pΗ, του ασκορβικού οξέος (mg/100g), των ολικών φαινολών (mg GAE / g ν.β), της αντιοξειδωτικής ικανότητας (μmol A.O./g ν.β.) και τέλος την ποσότητα καψαϊκίνης στις 3 καυτερές ποικιλίες (Medina, Yanca Βέροιας, Yanca Δράμας). Γενικά στα ποιοτικά και μορφολογικά χαρακτηριστικά που μελετήθηκαν παρατηρήθηκε μεγάλη ποικιλομορφία. Οι τιμές της συγκέντρωσης των ολικών φαινολών κυμαίνονταν από 0.93 mg GAE/g ν.β (Μarbuka) έως 0.39 mg GAE/g ν.β (Ε.41.9933), του ασκορβικού οξέος από 87.1 mg/100g (Portobello) έως 37.8 mg/100g (Βanan) και της ολικής αντιοξειδωτικής ικανότητας από 20.215 μmol A.O/g ν.β (Medina) έως 7.77 μmol A.O/g ν.β (Ε.41.9957). Οι μετρήσεις δείχνουν ότι το περιβάλλον και οι καλλιεργητικές φροντίδες επηρεάζουν τα χαρακτηριστικά της κάθε ποικιλίας.
description: In this research were investigated 7 morphological and 8 qualitative characteristics of 25 sweet pepper cultivars (E.41.9816, Derby, Raiko, Rubiero, Marbuka, Yellow Kelly, E.41.9957, Fierro ,E.41.9933, Thiaf, Palermo, Helsinki, Spider, Ferrari, Odyssey ,Orange Orangery, 35-136, Portobello, Yecla, 35-304, 35-103, Fuscinato, Banan, Fosoco, Costas or Florinis) and 3 chilly pepper cultivars (Μedina, Yanca Verias και Yanca Dramas). The 7 morphological characteristics were fruit and seed fresh and dry weight, fruit length and diameter and flesh thikness. The 8 qualitative characteristics were fruit color, the accumulation of soluble solids, total acidity (% citric acid), ascorbic acid content (mg/100g), total phenolics (mg GAE / g), antioxidant capacity (μmol A.O./g) and finally capsaicin content of 3 chilly cultivars (Μedina, Yanca Verias and Yanca Dramas). The concentration of total phenolics ranged from 0.93 mg GAE/g (Μarbuka) to 0.39 mg GAE/g (Ε.41.9933), total antioxidant capacity from 20.215 μmol A.O/g (Medina) to 7.77 μmol A.O/g (Ε.41.9957) and the concentration values of ascorbic acid ranged from 87.1 mg/100g (Portobello) to 37.8 mg/100g (Βanan). Furthermore, the data show that the environment and culture practice influence the characteristics of each cultivar.

Με το κάθε είδος εκτέλεσαν lay-up ώστε να μετρηθεί η μέγιστη και ελάχιστη γωνία της ποδοκνημικής καθώς και η μέγιστη δύναμη που εφαρμόζεται.Τα αποτελέσματα έδειξαν ότι παρόλο που υπάρχουν κάποιες διαφορές στις γωνίες της ποδοκνημικής μεταξύ των διαφορετικών ειδών υποστήριξης, αυτές δεν είναι στατιστικά σημαντικές. Μόνο για το swede-o παρατηρούμε μια τάση. Όσον αφορά τη μέγιστη δύναμη που εφαρμόζεται κατά την απογείωση και εδώ υπάρχουν κάποιες διαφοροποιήσεις οι οποίες όμως δεν είναι στατιστικά σημαντικές.

description: The purpose of this study is to examine if the functional taping and braces affect the ankle joint’s range of motion (plantar flrxion-dorsiflexion) as well as the maximum force that the basketball players exercise while making a very common movement in a basketball game, the lay-up.Eleven male basketball players, who participated in championships of national division, took part in the research. Three (3) kind of functional taping or braces were applied to each one of them (swede-o, air cast, tape).They were also measured wearing common sports shoes. They performed the lay up wearing every kind of functional taping and braces, so that the maximum and minimum angle of the ankle joint is measured as well as the maximum force exercised.The results of the measurements showed that, although there are some differences at the different ankles of the ankle joint between the three kinds of support, these are not statistically significant. A tendency to decline was only noticed for the swede-o. As for the maximum force exercised at the moment of the jump, there are also some variations, which are not significant.As a result, we can say that neither the functional taping nor the braces influence the range of motion of the ankle joint and the maximum force exercised.
Electron spectroscopy of single quantum objects to directly correlate the local structure to their electronic transport and optical properties

description: Physical property of a single quantum object is governed by its precise atomic arrangement. The direct correlation of localized physical properties with the atomic structures has been therefore strongly desired but still limited in the theoretical studies. Here, we have successfully examined the localized electronic properties of individual carbon nanotubes by means of high-resolution electron energy-loss spectroscopy combined with high-resolution transmission electron microscopy. Well-separated sharp peaks at the carbon K(1s) absorption edge and in the valence-loss spectra are obtained from a single freestanding carbon nanotube with the local chiral index and unambiguously identified as the transitions between the van Hove singularities. The spectra features clearly vary upon the different areas even in the individual carbon nanotube. Variations in interband transitions, plasmonic behaviors and unoccupied electronic structures are clearly attributed to the local irregular atomic arrangement such as topological defect and/or elastic bond stretching.

description: We report on the loading and trapping of ultracold atoms in a one dimensional permanent magnetic lattice of period 10 micron produced on an atom chip. The grooved structure which generates the magnetic lattice potential is fabricated on a silicon substrate and coated with a perpendicularly magnetized multilayered TbGdFeCo/Cr film of effective thickness 960 nm. Ultracold atoms are evaporatively cooled in a Z-wire magnetic trap and then adiabatically transferred to the magnetic lattice potential by applying an appropriate bias field. Under our experimental conditions trap frequencies of up to 90 kHz in the magnetic lattice are measured and the atoms are trapped at a distance of less than 5 micron from the surface with a measured lifetime of about 450 ms. These results are important in the context of studies of quantum coherence of neutral atoms in periodic magnetic potentials on an atom chip.

Teachers’ interventions and the growth of students’ mathematical understanding
Creators: name: Towers, Julie Margaret
Publisher: name: University of British Columbia

description: This study explores the ways in which teachers' interventions interact with and occasion the growth of students' mathematical understanding. Two 'cases' were documented, and these form the two strands of my research. The first strand concerns data collected in my own high school classroom at a time when I was a full-time teacher of mathematics in a small, rural secondary school in the United Kingdom. The second strand concerns data collected in a mathematics classroom in a large, urban high school in Vancouver, British Columbia. The data consist of videotaped lessons in each of the two classrooms, videotaped interviews with students from both strands of the data, copies of students' work from both strands, videotaped interviews with the Vancouver teacher, and my own journal entries. Analysis of the data, which is described in six stages, resulted in the generation of fifteen themes to describe the teachers' actions-in-the-moment. Three of these themes are distinguished from the others as teaching styles, as contrasted with the remaining twelve teaching strategies, and a number of the teaching strategies are clustered within the three teaching styles. The notion of a 'continuum of telling' is developed, upon which the three teaching styles lie, and this continuum is explored in order to probe the ways in which teachers' interventions interact with the growth of students' mathematical understanding. The ways in which teachers' interventions occasion the growth of students' mathematical understanding is probed through an integration of detailed traces of the students' growth of understanding with contemporaneous considerations of the teachers' strategies and styles. Implications to be drawn from these analyses, both for the research community and for teaching and learning, are discussed. I also share my reflections on my own growth as a teacher and as a researcher that I have experienced as a result of participating in, and conducting, this study.

description: Due to the acceleration of the black hole, the circular orbits of the photons will deviate from the equatorial plane and the property of the black hole shadow will change. We find that the latitude of the circular orbit increases with the increasing acceleration and then show that the observer's inclination angles which make the shadow radius and the shadow distortion maximum increase with the increasing acceleration for the accelerating Kerr black hole.

description: Creating high definition maps that contain precise information of static elements of the scene is of utmost importance for enabling self driving cars to drive safely. In this paper, we tackle the problem of drivable road boundary extraction from LiDAR and camera imagery. Towards this goal, we design a structured model where a fully convolutional network obtains deep features encoding the location and direction of road boundaries and then, a convolutional recurrent network outputs a polyline representation for each one of them. Importantly, our method is fully automatic and does not require a user in the loop. We showcase the effectiveness of our method on a large North American city where we obtain perfect topology of road boundaries 99.3% of the time at a high precision and recall.

description: Reduction of a state of a quantum system to a subsystem gives partial quantum information about the true state of the total system. Two subalgebras A1 and A2 of B(H) are called complementary if the traceless subspaces of A1 and A2 are orthogonal (with respect to the Hilbert-Schmidt inner product). When both subalgebras are maximal Abelian, then the concept reduces to complementary observables or mutually unbiased bases. In the paper several characterizations of complementary subalgebras are given in the general case and several examples are presented. For a 4-level quantum system, the structure of complementary subalgebras can be described very well, the Cartan decomposition of unitaries plays a role. It turns out that a measurement corresponding to the Bell basis is complementary to any local measurement of the two-qubit-system.

description: The study examined extent of fulfilment of campaign promises by those elected in the last ten years (2010-2020) in Anambra State, Nigeria. The study adopted descriptive survey research design. The population was eight thousand, five hundred and forty?one (8,541) respondents. The sample was 1,709 respondents, selected through a multi?stage sampling procedure which involved simple random, proportionate and accidental sampling techniques. Instrument used for data collection was a questionnaire tagged “Campaign Promises and Fulfilment Rating Scale” (CPFRS) developed by the researchers with four sections and 28 items meant to elicit responses on the three research questions of the study. Reliability estimate of the instrument was established as .73 using Cronbach alpha. Descriptive statistics involving mean, standard deviation, percentages and charts were adopted for data analysis. Results revealed that though candidates were able to identify areas of needs and promised to address them if elected, the extent to which such promises were kept is very poor. It was recommended, among others, that a law should be put in place to compel political office holders to fulfil all campaign promises when elected.

description: Στα πλαίσια της προσπάθειας, για μια ευρύτερη γνωριμία με το πρωτεϊνικό δυναμικό ορισμένων ελληνικών οινοποιήσιμων ποικιλιών και σύγκρισή τους με αντίστοιχες ξενικές, αναλύθηκαν 16 γλεύκη λευκών ποικιλιών από διάφορες αμπελουργικές περιοχές της Ελλάδας. Η ανάλυση των δειγμάτων γλεύκους για τον προσδιορισμό του πρωτεϊνικού τους προφίλ πραγματοποιήθηκε με τη χρήση της SDS - PAGE ηλεκτροφόρησης, όπου χρησιμοποιείται μια πηκτή πολυακρυλαμιδίου ως μέσο υποστήριξης και SDS (Sodium Dodecyl Sulfate) ως μέσο αποδόμησης των πρωτεϊνών. Αρχικά έγινε αξιολόγηση της μεθόδου (ηλεκτροφόρηση) και ειδικότερα στο σημείο που σχετίζεται με την απομόνωση των πρωτεϊνών από τα διάφορα γλεύκη. Εξετάστηκαν τρείς μέθοδοι απομόνωσης, η καταβύθιση με αιθανόλη, η λυοφιλίωση μετά από καταβύθιση με θειικό αμμώνιο και η συμπύκνωση με γλυκόλη πολυαιθυλενίου μετά από διήθηση σε μεμβράνες διαχωρισμού, με την τελευταία να επιλέγεται ως πιο εύχρηστη και πιο αξιόπιστη. Στη συνέχεια, χρησιμοποιήθηκε η τροποποιημένη μέθοδος Bradford για να υπολογιστεί η συγκέντρωση των διαλυτών πρωτεϊνών στο γλεύκος των διαφόρων ποικιλιών. Το πρωτεϊνικό άζωτο κυμάνθηκε από 4,58 – 25,02 g/l για το γλεύκος από τους συμβατικούς αμπελώνες και από 7,08 - 18,4 g/l για το γλεύκος από τους αντίστοιχους βιολογικούς. Τέλος, μετά από ηλεκτροφόρηση, επετεύχθη η κατανομή των πρωτεϊνών του γλεύκους σε διάφορες ζώνες. Το μεγαλύτερο μέρος των πρωτεϊνών εντοπίστηκε στην περιοχή των μικρών έως μέσων ΜΒ, οι οποίες φαίνεται να είναι υπεύθυνες για το πρόβλημα που εμφανίζεται σε λευκούς οίνους και γλεύκη, γνωστό ως πρωτεϊνικό θόλωμα.
description: Sixteen musts of white grape varieties, from several greek viticultural regions, were analyzed using SDS - PAG Electrophoresis in order to determine their protein profile. Initially, the method (electrophoresis) was evaluated and especially to the point that is related with the isolation of the protein. Then, using the Bradford method, the concentration of the soluble protein was estimated in the different musts. The protein nitrogen was fluctuated from 4,58 to 25,05 mg/lt concerning the musts that come from grapes of conventional vineyards and from 7,08 to 18,4 mg/l concerning the musts that come from grapes of organic vineyards. With the use of SDS - PAG Electrophoresis, the distribution of the proteins in several zones was succeded. The biggest part of the proteins was found in the area of the low or the middle molecular weights, which are responsible for a usual protein defect of white wines.

description: Hexaquark wave function with the quantum numbers $I(J^P)=0(3^+)$, which might be relevant for $d^*(2380)$, is constructed under an assumption that this is composed only of $u,d$ quarks in an $S$-wave. By combining three diquarks of either type, ($\bm{\bar{3}}_c, I=1$) or ($\bm{6}_c, I=0$), we demonstrate that there are five possible configurations for the six-quark state. The fully antisymmetric wave function is constructed by linearly combining the five configurations on an equal footing. We then take this wave function as well as the five configurations to calculate the hexaquark mass using the contact type effective potential consisting of the color-spin, color electric and constant shift. The mass is found to be the same regardless of the configurations being used including the fully antisymmetric one. This result can be traced to the fact that the hexaquark system has a freedom in choosing three diquarks in the construction of its wave function. The calculated hexaquark mass using the empirical parameters independently fixed from the baryon spectroscopy is found to be around $2342$ MeV, which is indeed very close to the experimental mass of $d^*(2380)$. Therefore, the hexaquark picture is promising for $d^*(2380)$ as far as the mass is concerned.

description: We develop a novel method to analyze the excluded volume of the multicomponent mixtures of classical hard spheres in the grand canonical ensemble. The method is based on the Laplace-Fourier transform technique and allows one to account for the fluctuations of the particle number density for the induced surface and curvature tensions equation of state. As a result one can go beyond the Van der Waals approximation by obtaining the suppression of the induced surface and curvature tensions coefficients at moderate and high packing fractions. In contrast to the standard induced surface and curvature tensions equation of state the suppression of these coefficients is not an exponential one, but a power-like one. The obtained alternative equation of state is further generalized to account for higher virial coefficients. This result is straightforwardly generalized to the case of quantum statistics.

description: In the paper, we apply the $k_T$ factorization approach to deal with the $B\to K$ transition form factor with tensor current in the large recoil regions. Main uncertainties for the estimation are discussed and we obtain $F_T^{B\to K}(0)=0.25\pm0.01\pm0.02$, where the first error is caused by the uncertainties from the pionic wave functions and the second is from that of the B-meson wave functions. This result is consistent with the light-cone sum rule results obtained in the literature.

description: Computer innovation at the post-secondary level can burden the instructor in terms of the time, expense and effort required to develop multimedia, computer-based instructional modules that keep pace with the rapid rate of research output. This study describes a successful instructor-developer multimedia collaboration that created a learning environment module for a post-secondary astronomy lab. A learning environment design model developed by Duchastel (1994) guided the team's development of the module. Internet-based tools and resources were used to help reduce development time and expense. The study investigated the requisite conditions to ensure success of the collaboration, the roles and responsibilities of the members, and the efficiency and cost-effectiveness of the collaborative development. The study's collaboration resulted in a useful learning package consisting of a set of Web pages collectively called PLANET; (the PLAnetary NETscape® interface) and uses Netscape's® Navigator™ to view the contents. This module has the attributes of a true research project. For example, the Netscape® interface enabled the first year astronomy students to locate and obtain images of Mars from the Internet in real time, and analyze them, in the same way as a planetary scientist. The results of the study indicate that a successful collaboration share the qualities of a friendship including similarities, trust, risk sharing, and symmetry. When these requisite conditions exist, then the time and funding limitations of developing a multimedia learning module are lessened. The study also showed that the collaborative development process is efficient when roles are established and maintained, and is an effective and inexpensive procedure for producing learning resources for post-secondary education.

description: O imbricamento entre palavra e imagem é inerente às linguagens artísticas. Na literatura, metáforas visuais são convocadas por meio do texto, ao passo que nas artes visuais, confere-se materialidade à palavra, dotando-a de cor e forma. Nessa perspectiva, emerge a produção da artista visual Elida Tessler, cuja poética centraliza-se na escrita, resultando em criações que são um híbrido de arte e literatura. A artista possui um amplo acervo que orbita em torno da palavra, explorando seus atributos tanto verbais quanto pictóricos. Em várias de suas obras, Tessler estabelece relações com a linguagem da literatura, incorporando trechos de livros para construir narrativas visuais. A instalação “Meu nome também é vermelho” está inserida nessa premissa, sua construção poética se constitui por meio da apropriação do livro “Meu nome é vermelho” de Orhan Pamuk. Nesse sentido, o presente artigo explora as conexões entre imagem e palavra, bem como as inter-relações entre visualidade e textualidade, tendo a obra “Meu nome também é vermelho” como ponto focal dessa investigação.
