description: Il testo Soluzioni Civili. Praticare economia civile nei territori, attraverso un’ampia e stimolante carrellata di pratiche e strumenti, introduce al tema dell’economia civile, un modello che, come ci ricordano gli autori, coniuga mercato, fasce deboli, sostenibilità ambientale e civismo. Numerose sono le suggestioni che emergono dalla lettura che ci guida alla scoperta di un approccio basato sul protagonismo della comunità, proposto come strada per affrontare le sfide socio-ambientali che caratterizzano la nostra epoca. Dal punto di vista geografico appare di assoluto interesse la contestualizzazione territoriale dei diversi spunti teorici attraverso numerosi esempi che intercettano diverse scale, seppur concentrandosi su quella locale. Inoltre, sin dal suo inizio emerge la centralità esplicitamente dichiarata dell’azione territoriale, come perno dell’economia civile, collegata all’importanza che “la lettura” del territorio assume nella sua accezione sistemica, che contempla le componenti sociali, economiche ed ecologiche e le loro relazioni.

About the journey. stasis, chiasmus and interruption. A geography essay di Giovanni Messina

Year: 2023

description: È il viaggio il tema che Giovanni Messina affronta in questo snello volume di circa 70 pagine (comprendenti foto e prefazione di Giulia de Spuches) visto in una prospettiva del tutto originale. Dopo aver richiamato gli studi geografici che si sono soffermati sul suo significato geografico e quelli provenienti dal mondo letterario che ne hanno messo in evidenza le implicazioni esistenziali, l’A. approda infine al tema degli sbarchi migratori con il loro drammatico portato umanitario. Una prospettiva così vasta e composita può essere affrontata esclusivamente da ricercatori che possiedono raffinati strumenti analitici. Nel caso del nostro A., la strumentazione da lui adottata, oltre che alla sua formazione di geografo, gli proviene dalla semiologia linguistica che, mediante l’analisi del piano connotativo delle parole, gli offre raffinate metafore in grado di sviscerare il significato del viaggio, spaziando da quello esistenziale, a quello metafisico, per finire a quello della mobilità geografica.

description: Εκτιμάται ότι το 50% της έκτασης της γης βρίσκεται σε διακρατικές λεκάνες απορροής, ποσοστό που συνεχώς αυξάνεται με τη δημιουργία νέων κρατών, ενώ εκτιμάται ότι περίπου το 40% του συνολικού πληθυσμού κατοικεί σε διακρατικές λεκάνες. Σύμφωνα με ιστορικά στοιχεία, οι ασυμφωνίες σχετικά με διακρατικούς υδατικούς πόρους δεν έχουν οδηγήσει έως σήμερα σε βίαιες διαμάχες, αλλά αναμένεται ότι μελλοντικά το νερό θα «αντικαταστήσει» το πετρέλαιο ως τη βασική αιτία πολέμων. Τα προβλήματα διακρατικής φύσεως σε συνδυασμό με την απειλή της εξάντλησης των υδατικών πόρων, θέτουν τη διαχείριση των διακρατικών λεκανών απορροής ως ένα καίριο ζήτημα της εποχής όπου απαιτείται η εύρεση συνεργατικών λύσεων για την πολιτική σταθερότητα της περιοχής, την περιβαλλοντική προστασία και την ισότιμη εκμετάλλευση των κοινών υδατικών πόρων. Σκοπός της παρούσας διατριβής είναι η πρόταση μίας μεθοδολογίας διαχείρισης διακρατικών υδάτων μέσα στο θεσμικό και νομικό πλαίσιο όπως αυτό ορίζεται από διεθνείς οδηγίες και συμβάσεις, η οποία θα συνεισφέρει στην εξομάλυνση αντιθέσεων που συχνά προκύπτουν σε διακρατικές λεκάνες. Βασισμένη στις αρχές της Ολοκληρωμένης Διαχείρισης Υδατικών Πόρων, η προτεινόμενη μεθοδολογία καλύπτει όλα τα στάδια των διακρατικών σχέσεων σχετικών με το νερό, ξεκινώντας από τη φάση των διαπραγματεύσεων, στη συνέχεια στη σύναψη της συμφωνίας για τα κοινά ύδατα και τέλος προτείνει τους μηχανισμούς που θα υποστηρίξουν την εφαρμογή της βιώσιμης διαχείρισης των διακρατικών υδάτων
description: It is estimated that 50% of the global surface is lying on transboundary catchments and this percentage is continually increasing due to the creation of new nations, while around 40% of the earth’s population residents in transboundary water catchments. According to historical facts, no record exists of hostility due to shared water resources, but it is anticipated that in the future water will replace oil as the primary cause of war. Problems of transboundary nature in connection with the imminent threat of water shortage render the management of transboundary catchments a crucial issue that demands co-operative mechanisms for the preservation of the political stability, the environmental protection and the equitable use of the shared water resources. The aim of the thesis is the development of a methodology for the management of transboundary water resources in compliance with the institutional and international legal framework contributing to conflict resolution in transbounary catchments. Based on the principles of integrated water management, the proposed methodology covers all the phases of the inter-country relations regarding water issues, starting from the negotiation phase to the signing of a water agreement and proposing essential mechanisms that will support the implementation of the agreement and the sustainable management of the shared water resources

description: This study aimed to evaluate the characteristics of Calu-3 cells as a model to examine the toxicological responses of inhalable substances. Calu-3 cells were grown to the confluence at an air-liquid interface (ALI) using a Transwell® permeable support system. The ALI resulted in biomimetic native bronchial epithelium displaying pseudostratified columnar epithelium with more microvilli and secretory vesicles. We further characterized and optimized the Calu-3 cell line model using ALI culturing conditions, immunolabeling of protein expression, ultrastructural analysis using scanning electron microscopy (SEM), and transepithelial electrical resistance (TEER) measurements, and then screened for the cytotoxicity of tobacco flavoring extracts. Calu-3 cells displayed dose-dependent responses when treated with the flavoring extract. Within 8–10 days, cell monolayers developed TEER ≥1000 Ω·cm2. During this time, Calu-3 cells exposed to flavoring extracts X01 and X06 exhibited a loss of cellular integrity and decreased ZO-1 and E-cadherin protein expression. In conclusion, we investigated the Calu-3 cell line culture conditions, culture time, and barrier integrity and tested the effect of six new synthetic tobacco flavoring extracts. Our data demonstrate that the Calu-3 human bronchial epithelial cell monolayer system is a potential in vitro model to assess the inhalation toxicity of inhalable substances.

description: Almost all fields of science rely upon statistical inference to estimate unknown parameters in theoretical and computational models. While the performance of modern computer hardware continues to grow, the computational requirements for the simulation of models are growing even faster. This is largely due to the increase in model complexity, often including stochastic dynamics, that is necessary to describe and characterize phenomena observed using modern, high resolution, experimental techniques. Such models are rarely analytically tractable, meaning that extremely large numbers of stochastic simulations are required for parameter inference. In such cases, parameter inference can be practically impossible. In this work, we present new computational Bayesian techniques that accelerate inference for expensive stochastic models by using computationally inexpensive approximations to inform feasible regions in parameter space, and through learning transforms that adjust the biased approximate inferences to closer represent the correct inferences under the expensive stochastic model. Using topical examples from ecology and cell biology, we demonstrate a speed improvement of an order of magnitude without any loss in accuracy. This represents a substantial improvement over current state-of-the-art methods for Bayesian computations when appropriate model approximations are available.
Characterization of a ras and a ras-related gene and their developmental expression in the cellular slime mould Dictyostelium discoideum
Creators: name: Robbins, Stephen Mark
Publisher: name: University of British Columbia
Year: 2011

description: Although it was previously reported that Dictyostelium discoideum possessed a single ras gene (Ddras) that was maximally expressed during the pseudoplasmodial stage of development, a second ras gene (DdrasG), has been isolated and characterized. It encodes a protein that is similar to the protein encoded by Ddras and the human ras proteins. However, in contrast to Ddras, the DdrasG gene was only expressed during growth and early development. The two ras proteins may fulfill different functions: the DdrasG protein having a role during cell growth and the Ddras protein having a role in signal transduction during multicellular development. However, the expression of the DdrasG gene throughout development did not appear to have a detrimental effect on differentiation. Although other eukaryotic organisms possess more than one ras gene, D. discoideum is thus far unique in expressing different ras genes at different stages of development. Ras genes are members of a large ras-related multigene family that has been found in a wide variety of organisms. A ras-related gene was isolated from D. discoideum that hybridized to both the Ddras and DdrasG genes under low, but not under high stringency conditions. The predicted amino acid sequence shows a high degree of sequence identity with the human rap proteins and thus has been designated Ddrapl. During vegetative and early development a single 1.1 kb mRNA was present, but by aggregation this transcript was no longer detected and two new transcripts of 1.0 and 1.3 kb were observed and were present throughout the remainder of development. The maximum levels of the Ddrapl specific mRNAs appeared during aggregation and culmination, developmental stages where the levels of DdrasG and Ddras messages were declining. The reciprocal nature of the Ddrapl gene expression with respect to that of the two ras genes suggests the possibility that the ras and rap gene products in D. discoideum have antagonistic roles. Antibodies that are specific for the Ddras, DdrasG and Ddrapl proteins have been generated and can be used to help elucidate the biological functions of the individual proteins.
Early Controversies over Athetosis: I. Clinical Features, Differentiation from other Movement Disorders, Associated Conditions, and Pathology
Creators: name: Lanska, Douglas John
Publisher: name: Tremor and Other Hyperkinetic Movements
Year: 2013

description: Background: Since the description of athetosis in 1871 by American neurologist William Alexander Hammond (1828-1900) the disorder has been a source of controversy, as were many aspects of Hammond’s career. Methods: Review of controversies in the semi-centennial since the description of athetosis. Results: Hammond struggled to establish athetosis as a distinct clinic-pathological entity, and had successfully predicted the striatal pathology in his initial case (albeit somewhat serendipitously). Athetosis was, nevertheless, considered by many neurologists to be a form of post-hemiplegic chorea or part of a continuum between chorea and dystonia. European neurologists, and particularly the French, initially ignored or discounted the concept. Additional controversies arose over whether the movements persisted during sleep, whether athetosis was, or could be, associated with imbecility or insanity, and how it should be treated. Discussion: Some controversies concerning athetosis served to identify areas where knowledge was insufficient to make accurate statements, despite prior self-assured or even dogmatic statements to the contrary. Other controversies illustrated established prejudices, even if these biases were often only apparent with the greater detachment of hindsight.

description: Two cognitive models was studied : conceptual metaphor & class inclusion models. Four different studies was conducted in Greece and Costa Rica, analyzing the production(studies 1&2), and two comprehension(studies 3&4) as well as the role of language. The results of studies 1 and 2 support the conceptual metaphor theory in relation to the production of metaphors. Study 4 also supports these theory in relation to the comprehension, but only in Costa Ricas' sample. More research is needed because there is some evidence that suggest that a group of metaphors could be associated within a class inclusion mechanism

description: Harmonic comb state has proven to be emerging in quantum cascade lasers and promoted by an interplay between parametric gain and spatial hole burning. We report here on robust, pure, self-starting harmonic mode locking in Copper-based double-metal THz quantum cascade lasers. Different harmonic orders can be excited in the same laser cavity depending on the pumping condition and stable harmonic combs spanning more than 600 GHz bandwidth at 80 K are reported. Such devices can be RF injected and the free running coherence is assessed by means of self-mixing technique performed at 50 GHz. A theoretical model based on Maxwell-Bloch equations including an asymmetry in the gain profile is used to interpret the data.

Review of Prevalence Studies of Tic Disorders: Methodological Caveats
Creators: name: Cubo, Esther
Publisher: name: Tremor and Other Hyperkinetic Movements
Year: 2012

description: Introduction: Tic disorders are neurodevelopmental disorders of childhood associated with psychiatric comorbidity and academic problems. Estimating the prevalence and understanding the epidemiology of tic disorders is more complex than was once thought. Until fairly recently, tic disorders were thought to be rare, but today tics are believed to be the most common movement disorder, with 0.2–46.3% of schoolchildren experiencing tics during their lifetime. Tentative explanations for differing prevalence estimates include the multidimensional nature of tics with a varied and heterogeneous presentation, and the use of different epidemiological methods and study designs. Methods: Literature review and analysis of methodological issues pertinent to epidemiological studies of tic disorders. Results: Epidemiological studies of tic disorders were reviewed, and the main elements of epidemiological studies, including sample selection, case ascertainment strategy, definition of tic disorders, and the degree of coverage of the eligible population (i.e., the response rate) were examined. Discussion: In order to improve the quality of epidemiological studies of tic disorders, a number of recommendations were made, including but not limited to a review of the diagnostic criteria for tic disorders, and inclusion of new tic disorder categories for those with tics of secondary etiology.

description: The Grothendieck group of the tower of symmetric group algebras has a self-dual graded Hopf algebra structure. Inspired by this, we introduce by way of axioms, a general notion of a tower of algebras and study two Grothendieck groups on this tower linked by a natural paring. Using representation theory, we show that our axioms give a structure of graded Hopf algebras on each Grothendieck groups and these structures are dual to each other. We give some examples to indicate why these axioms are necessary. We also give auxiliary results that are helpful to verify the axioms. We conclude with some remarks on generalized towers of algebras leading to a structure of generalized bialgebras (in the sense of Loday) on their Grothendieck groups.

description: Aims.Analysis of the innermost regions of the carbon-rich star IRC+10216 and of the outer layers of its circumstellar envelope have been performed in order to constrain its mass-loss history. Methods: .We analyzed the high dynamic range of near-infrared adaptive optics and the deep V-band images of the circumstellar envelope of IRC+10216 using high angular resolution, collected with the VLT/NACO and FORS1 instruments. Results: .From the near-infrared observations, we present maps of the sub-arcsecond structures, or clumps, in the innermost regions. The morphology of these clumps is found to strongly vary from J- to L-band. Their relative motion appears to be more complex than proposed in earlier works: they can be weakly accelerated, have a constant velocity, or even be motionless with respect to one another. From V-band imaging, we present a high spatial resolution map of the shell distribution in the outer layers of IRC+10216. Shells are resolved well up to a distance of about 90'' to the core of the nebula and most of them appear to be composed of thinner elongated shells. Finally, by combining the NACO and FORS1 images, a global view is present to show both the extended layers and the bipolar core of the nebula together with the real size of the inner clumps. Conclusions: .This study confirms the rather complex nature of the IRC+10216 circumstellar environment. In particular, the coexistence at different spatial scales of structures with very different morphologies (clumps, bipolarity, and almost spherical external layers) is very puzzling. This confirms that the formation of AGB winds is far more complex than usually assumed in current models.

Fragile X-Associated Tremor Ataxia Syndrome: The Expanding Clinical Picture, Pathophysiology, Epidemiology, and Update on Treatment
Creators: name: Hall, Deborah Ann

Publisher: name: Tremor and Other Hyperkinetic Movements
Year: 2012

description: Fragile X-associated tremor/ataxia syndrome (FXTAS) is a progressive degenerative movement disorder characterized by kinetic tremor, cerebellar gait ataxia, parkinsonism, and cognitive decline. This disorder occurs in both males and females, frequently in families with children who have fragile X syndrome. The clinical features of this disorder, both classic and newly described, are summarized in this paper. In screening studies, fragile X mental retardation 1 (FMR1) gene premutation (55–200 CGG) expansions are most frequently seen in men with ataxia who have tested negative for spinocerebellar ataxias. Since the original description, the classic FXTAS phenotype has now been reported in females and in carriers of smaller (45–54 CGG) and larger (>200 CGG) expansions in FMR1. Premutation carriers may present with a Parkinson disease phenotype or hypotension, rather than with tremor and/or ataxia. Parkinsonism and gait ataxia may also be seen in individuals with gray zone (41–54 CGG) expansions. Studies regarding medication to treat the symptoms in FXTAS are few in number and suggest that medications targeted to specific symptoms, such as kinetic tremor or gait ataxia, may be most beneficial. Great progress has been made in regards to FXTAS research, likely given the readily available gene test and the screening of multiple family members, including parents and grandparents, of fragile X syndrome children. Expansion of genotypes and phenotypes in the disorder may suggest that a broader disease definition might be necessary in the future.

description: With the increasing demand for audio communication and online conference, ensuring the robustness of Acoustic Echo Cancellation (AEC) under the complicated acoustic scenario including noise, reverberation and nonlinear distortion has become a top issue. Although there have been some traditional methods that consider nonlinear distortion, they are still inefficient for echo suppression and the performance will be attenuated when noise is present. In this paper, we present a real-time AEC approach using complex neural network to better modeling the important phase information and frequency-time-LSTMs (F-T-LSTM), which scan both frequency and time axis, for better temporal modeling. Moreover, we utilize modified SI-SNR as cost function to make the model to have better echo cancellation and noise suppression (NS) performance. With only 1.4M parameters, the proposed approach outperforms the AEC-challenge baseline by 0.27 in terms of Mean Opinion Score (MOS).

description: The $^{55}$Mn$(d,n)^{56}$Fe differential cross section is measured at $E_d=7$ MeV\@. The $^{56}$Fe level density obtained from neutron evaporation spectra is compared to the level density extracted from the $^{57}$Fe$(^3$He,$αγ)^{56}$Fe reaction by the Oslo-type technique. Good agreement is found between the level densities determined by the two methods. With the level density function obtained from the neutron evaporation spectra, the $^{56}$Fe $γ$-strength function is also determined from the first-generation $γ$ matrix of the Oslo experiment. The good agreement between the past and present results for the $γ$-strength function supports the validity of both methods and is consistent with the low-energy enhancement of the $γ$ strength below $\sim 4$ MeV first discovered by the Oslo method in iron and molybdenum isotopes.

description: Background: A number of neurological conditions have been reported to be associated with gluten sensitivity, including ataxia, peripheral neuropathy, epilepsy, and occasionally, chorea. The pathogenic role of anti-gliadin antibodies has been questioned, and pathophysiology remains controversial. Case Report: I report chorea in a patient with celiac disease, which responded to a gluten-restricted diet. The response of the movement disorder to change in diet strongly suggests a functional role for anti-gliadin antibodies in the generation of chorea, probably involving basal ganglia targets. Discussion: Gluten sensitivity may be a treatable cause of chorea.

description: The authors consider that in our days is very important for us to know the laws of universe. The fundamental contribution of the authors are the parallel between the laws of the universe and the concept of quality management. If one gets to understand and to practice these laws, one can reach self-knowledge and, ultimately, perfection. The most important laws of the universe are: law of love, law of forgiveness, law of mercy, law of blessing, law of rhythm, law of correspondence, law of attraction, law of learning. Leaders have to realize that personal example is the best way to determine the employees to adapt the behavior needed to improve the quality culture throughout the organization. A leader can not create a fairness and ethical model for behavior, establishing a culture of trust and integrity, being a positive example to employees without respecting and applying spiritual laws. For example, what would a leader be if not taking into account the law of cause and effect, knowing that we reap what we sow? How about respecting harmony law cause we have to treat the others the way we want to be treated? Each law is important in itself, as it represents a step towards self-knowledge and of the others...but together we can climb the steps towards knowledge and love.

A model featuring dense gluonic hot spots as first proposed by van Hove predicts that the observables under investigation would have sensitivity to such a substructure should it occur, and the model also motivates selection of transverse momenta in the range 0.8 < p_t < 2.0$ GeV/c. Both CD and CI correlations of high statistical significance are observed and possible interpretations are discussed.

Manitoba's regional development corporations : lessons for locally-based rural development
Creators: name: Becker, David A.

description: Over the last century the Prairie region has undergone a transition from predominantly rural to predominantly urban settlement. By the early 1900s emphasis began to shift from rural-based primary activities to urban-based industrial activity. One product of this transition was the marginalization of rural communities. An examination of literature pertinent to Canadian development policy reveals no single solution to rural decline. Instead there are numerous theories and recommendations which communities can adopt. One such strategy has been locally-based development. The purpose of this thesis is to contribute to knowledge concerning what locally-based organizations can do to mitigate the impact of decline in rural communities. As a case study, Manitoba's Regional Development Corporations (RDCs) are analyzed within the context of the provincial government's overall approach for rural development in order to investigate their effectiveness in contributing to locally-based rural development. This effectiveness is measured in goals, strategies and processes of an RDC as they changed over three periods: (1) 1963/73, (2)1973/83, (3) 1983/90. In each period the following questions were asked: 1. What priorities or objectives were emphasized in provincial development policy? 2. What strategies were used by the province and RDCs to achieve rural development? 3. What role was established for locally-based participation? Throughout the three study periods the province's regional policies remained based on laissez-faire economic principles, while the RDC approach was oriented to regional-national integration (i.e., merging of regional economic activity with national and international markets). The conclusion is that RDCs affected rural development by enhancing the abilities of local businesses participating in the provincial marketplace. RDCs have concentrated on supporting a process for adapting to rural transition, rather than reversing forces impinging on rural communities. Lessons extended from the RDC study suggest that if efforts to enhance a rural area's competitive position in national or international markets become the principal objective for local development, the unique qualities associated with rural life may be difficult to maintain.

description: The predominant reason for the damaging power of high-energy radiation is multiple ionization of a molecule, either direct or via the decay of highly excited intermediates, as e.g., in the case of X-ray irradiation. Consequently, the molecule is irreparably damaged by the subsequent fragmentation in a Coulomb explosion. In an aqueous environment, however, it has been observed that irradiated molecules may be saved from fragmentation presumably by charge and energy dissipation mechanisms. Here, we show that the protective effect of the environment sets in even earlier than hitherto expected, namely immediately after single inner-shell ionization. By combining coincidence measurements of the fragmentation of X-ray-irradiated microsolvated pyrimidine molecules with theoretical calculations, we identify direct intermolecular electronic decay as the protective mechanism, outrunning the usually dominant Auger decay. Our results demonstrate that such processes play a key role in charge delocalization and have to be considered in investigations and models on high-energy radiation damage in realistic environments.

description: Background: Essential tremor (ET) and Parkinson's disease (PD) are probably the most common movement disorders. As ethnic differences have been reported in ET, we designed the present study to evaluate the prevalence of ET and that of Parkinson's disease (PD) in the Druze villages of northern Israel. Methods: A two-phase, door-to-door survey was undertaken. Residents aged ≥51 years who agreed to participate and answered “yes” to tremor or PD-related screening questions and 3% of subjects who screened negative were evaluated. Diagnostic criteria for ET were similar to those used in Sicilian and Spanish studies. PD was diagnosed according to Gelb's criteria. Results: The target population consisted of 9,086, the study cohort of 3,980 residents. Tremor was observed in 36 subjects. In 27, the tremor fully met the criteria for ET. The prevalence of ET (age ≥65) was 1.49% (95% CI 0.91–2.07%). PD was diagnosed in 23 subjects. The prevalence of PD (age ≥65) was 1.13 (95% CI 0.62–1.64%). Leucine-rich repeat protein kinase 2 (G2019S mutation) was evaluated in subjects diagnosed with tremor PD and those screened for assessment of the validity of the questionnaire. None carried the mutation. Discussion: The prevalence of ET in the Druze population is low and similar to the prevalence of PD.

description: The aim of the paper is to analyze the evolution of the concept of sustainability and the central role of the public organizations for the sustainable development. Nowadays sustainability is at the forefront of many organization’s agenda. The recent evolution in the role of public organizations has led to the recognition of a social and environmental aspect to their activities which obliges them to seek sustainable growth. There is a disjoint between the public sector’s central role in sustainable development and its actual participation in the endeavor. The reason behind this is the difficulty in integrating the numerous needs of citizens and requirements of different cultures. This study analyses a model that explains how sustainability can help to improve the quality of the life of citizens. The paper explores the link between culture and sustainability from a public organization perspective and it examines how culture must be integrated within public sector organizations planning. This research considers that the goal of sustainable development is to enable all people to satisfy their basic needs and enjoy a better quality of life, without compromising the quality of life of future generations. We argue that sustainable development offers the most appropriate set of values for the creation and maintenance of public value.

description: Two dimensional layered van der Waals (vdW) magnets have demonstrated their potential to study both fundamental and applied physics due to their remarkable electronic properties. However, the connection of vdW magnets to spintronics as well as quantum information science is not clear. In particular, it remains elusive whether there are novel magnetic phenomena only belonging to vdW magnets, but absent in the widely studied crystalline magnets. Here we consider the quantum correlations of magnons in a layered vdW magnet and identify an entanglement channel of magnons across the magnetic layers, which can be effectively tuned and even deterministically switched on and off by both magnetic and electric means. This is a unique feature of vdW magnets in which the underlying physics is well understood in terms of the competing roles of exchange and anisotropy fields that contribute to the magnon excitation. Furthermore, we show that such a tunable entanglement channel can mediate the electrically controllable entanglement of two distant qubits, which also provides a protocol to indirectly measure the entanglement of magnons. Our findings provide a novel avenue to electrically manipulate the qubits and further open up new opportunities to utilize vdW magnets for quantum information science.

description: Με σκοπό την διερεύνηση των φαινομένων μεταφοράς κατά την ξήρανση γεωργικών προϊόντων με ρεύμα θερμού αέρα αναπτύχθηκε μοντέλο περιγραφής της διεργασίας βασιζόμενο στα ισοζύγια θερμότητας και μάζας, θεωρώντας το στερεό ως μία επίπεδη πλάκα ξηραινόμενη και συρρικνούμενη και από τις δύο πλευρές. Οι θερμοφυσικές ιδιότητες του προϊόντος και του αέρα ξήρανσης ελήφθησαν από την βιβλιογραφία ενώ οι συντελεστές μεταφοράς θερμότητας και μάζας καθώς και ο συντελεστής διάχυσης υγρασίας συσχετίσθηκαν με πειραματικά αποτελέσματα. Η επαλήθευση του θεωρητικού μοντέλου διενεργήθηκε συγκρίνοντας τα αποτελέσματα της προσομοίωσης με αποτελέσματα που ελήφθησαν από εκτεταμένη πειραματική διερεύνηση. Η πειραματική διερεύνηση της διεργασίας διενεργήθηκε σε πειραματικό ξηραντήριο τύπου σήραγγας, σε διάφορες θερμοκρασίες και ταχύτητες αέρα, χρησιμοποιώντας σύκα ξηραινόμενα σε ρεύμα θερμού αέρα κινούμενο παράλληλα προς την επιφάνεια του προϊόντος. Από την σύγκριση αποδείχθη ότι το μοντέλο προσομοιώνει πολύ καλά την συμπεριφορά του προϊόντος κατά την ξήρανση στις χαμηλότερες θερμοκρασίες ενώ στις μεγαλύτερες θερμοκρασίες επιτυγχάνεται ικανοποιητική προσέγγιση της διεργασίας
description: For the purpose of a theoretical investigation of the transport phenomena during the drying of agricultural products by means of a preheated air stream, a model simulating the drying process, considering the solid product as a plate dried and shrank on both surfaces, has been developed. The thermophysocal properties of the drying air and of the dried product necessary for the model application have been taken from the scientific literature, while new relations describing the heat and mass transfer phenomena by using properly correlated experimental results, have been developed. The validation of the model has been carried out by comparison of the simulation with experimental results obtained by extensive experimental investigation of figs using an experimental, tunnel-type dryer of small capacity of fresh product. The comparison of the results obtained from the application of the model demonstrated the excellent simulation of the drying process for low and medium drying air temperatures and the good one at high temperatures

description: We calculate the CP-averaged branching ratios and CP-violating asymmetries of a number of two-body charmless hadronic decays $\bar{B_s^0} \to PP, PV, VV$ in the perturbative QCD (pQCD) approach to leading order in $α_s$ (here $P$ and $V$ denote light pseudoscalar and vector mesons, respectively). The mixing-induced CP violation parameters are also calculated for these decays. We also predict the polarization fractions of $B_s \to VV$ decays and find that the transverse polarizations are enhanced in some penguin dominated decays such as $\bar{B_s^0} \to K ^{*}\bar{K^{*}}$, $K ^{*}ρ$. Some of the predictions worked out here can already be confronted with the recently available data from the CDF collaboration on the branching ratios for the decays $ \bar{B_s^0} \to K^+π^-$, $ \bar{B_s^0} \to K^+K^-$ and the CP-asymmetry in the decay $ \bar{B_s^0} \to K^+π^-$, and are found to be in agreement within the current errors. A large number of predictions for the branching ratios, CP-asymmetries and vector-meson polarizations in $\bar{B_s^0}$ decays, presented in this paper and compared with the already existing results in other theoretical frameworks, will be put to stringent experimental tests in forthcoming experiments at Fermilab, LHC and Super B-factories.
