title: Laboratoria przyszłości. Ekowioski jako projekty edukacyjno-utopijne
Creators: name: Krassowski, Marcin
Publisher: name: Instytut Pedagogiki Uniwersytetu Wrocławskiego
Year: 2020

description: Artykuł podejmuje problematykę oddolnych działań podejmowanych w obliczu światowego kryzysu klimatycznego. Za przykład podmiotów podejmujących takie działania służą ekowioski – tradycyjne lub intencjonalne społeczności mające na celu regenerację środowiska społecznego i naturalnego. W artykule przedstawiono analizę działań podejmowanych przez środowiska ekoosadnicze poprzez pryzmat dwóch metafor używanych na określenie ekowiosek: metafory ekowioski-laboratorium oraz ekowioski-utopii. Spojrzenie na funkcjonowanie tych społeczności poprzez wyżej wymienione metafory pozwala zobaczyć, w jaki sposób definiują przyczyny kryzysu środowiskowego oraz jakie cele przyświecają wypracowywaniu rozwiązań tych problemów. Wskazuję, że ekowioski można – inspirując się rozmyślaniami Bruno Latoura – postrzegać jako laboratoria przyszłości: miejsca diagnozowania globalnych problemów, poszukiwania ich rozwiązań w mikroskali i prób skalowania (upscaling) tych rozwiązań poprzez działania edukacyjne.

description: We assess the effect of a population of high-redshift quasars on the 21-cm power spectrum during the epoch of reionisation. Our approach is to implement a semi-numerical scheme to calculate the three-dimensional structure of ionised regions surrounding massive halos at high redshift. We include the ionising influence of luminous quasars by populating a simulated overdensity field with quasars using a Monte Carlo Markov Chain algorithm. We find that quasars modify both the amplitude and shape of the power spectrum at a level which is of the same order as the fractional contribution to reionisation. The modification is found both at constant redshift and at constant global neutral fraction, and arises because ionising photons produced by quasars are biased relative to the density field at a level that is higher than steller ionising photons. Our results imply that quasar ionisation will need to be included in detailed modelling of observed 21-cm power spectra.

description: Extensive biological data are currently readily available in public databases, making it possible for a specific research problem to be addressed by multi-database search and data retrieval. However, getting the correct interconnected data from a number of different databases can be cumbersome. Here, we present TAGOPSIN (TAxonomy, Gene, Ontology, Protein, Structure INtegrated), a command line program written in Java whose purpose is to retrieve data from seven public biological repositories and assemble them in a single data warehouse managed by PostgreSQL.
Using the object-oriented paradigm, organisms, genomes, genes, proteins, biological functions, protein domain families and protein 3D structures are modelled as real-world interrelated entities. Accordingly, TAGOPSIN retrieves selected data from their respective FTP or HTTP servers and gathers them in a unified local repository.
The program was tested with several model prokaryotic organisms. For example, about 1.1 million coding nucleotide sequences and 1,706 PDB entries were retrieved for 264 strains of Mycobacterium tuberculosis. TAGOPSIN constitutes a valuable tool in molecular evolutionary and other comparative genomics studies as well as structure-based studies.
TAGOPSIN is released under the GNU General Public License and is available as a JAR file at https://github.com/ebundhoo/TAGOPSIN.

description: Due to an ongoing increase in the average life expectancy and a decrease in the average birth rate, there are less active people that are of working age in the labor market. However, this year's Covid-19 pandemic highlighted that older workers are much more vulnerable in an ever-changing labor market. It is therefore essential to analyze how employers create working conditions for more senior employees during a pandemic. As well as the employment opportunities of older workers in the longer term. Applied methods of analysis: scientific literature and analysis of various documents, interviews, and analysis of the research results, their interpretation. The study found that older employees had difficulty adapting to changed working conditions and faced a higher risk of health issues. The article thus showed that existing stereotypes among employers limit the employability of older people.

description: The finite-volume QCD spectrum in the I = 1/2 , S = -1, parity-even, zero-momentum sectorcontaining the k meson and the I = 1, S = 0, parity-even, G-parity-odd, zero-momentum sector containing the a0(980) meson is studied with the inclusion of tetraquark operatorsusing lattice QCD. Several hundred tetraquark operators of different flavor, color, and spatial structures are included in this study. We find that the inclusion of tetraquark operators is crucial for determining the spectrum in each sector, and that there is a state in each sector with sizeable tetraquark component that is missed without the use of tetraquark operators. The spectrum of excited sigma baryons in the I = 1, S = -1, parity-even and parity-odd sectors is also studied using large bases of single- and two-hadron operators, for the first time in lattice QCD. We find qualitative agreement with experiment, and near-agreement with a previous study that neglects two-hadron operators. All calculations are performed using 412 gauge field configurations with clover-improved Wilson fermions on a 323 x 256 anisotropic lattice with mπ ≈230 MeV, and quark propagation is treated using the Stochastic LapH method.

description: Abstract: This study aimed to evaluate the livelihood assistance given by the social protection agency to persons-with-work-related disability (PWRDs) or to those workers who have met work-related contingency. Out of the 20 clients communicated by the researcher only 9 of them have responded with willingness to be interviewed. Data collection was done through interview utilizing questionnaires. These questionnaires were designed into a Google Form and was sent to each respondents by link through their online messaging accounts. The study explored into the bottlenecks in each of the following stages in the acquisition and implementation of the livelihood of the PWRDs: planning, attending livelihood training/seminar, purchasing, onset and lastly, maintenance of the livelihood. Majority of the respondents expressed difficulties during the onset and maintenance of their livelihood. The challenges during the onset is the presence of customer debts, no space to display products, lack of knowledge to advertise, no customer at times and lack of supplies to sell. Although majority of the clients have been able to maintain their livelihood, those who haven’t answered that their return to formal job employment and the recent pandemic brought about by COVID-19 were factors for their livelihood to fail.

description: Riassunto – Nel contributo l’intento dell’autore è verificare la sopravvivenza del termine “razza” nei sussidi parascolastici che si affiancavano ai manuali disciplinari nel secondo dopoguerra. Oggetto di indagine sarà costituito dall’enciclopedia “Vita Meravigliosa”, pubblicata a Milano a partire dal 1953 sotto la direzione di Renzi Roberto, Gino Conte e Carlo Porta, e ristampata più volte negli anni successivi. Questi supporti all’apprendimento delle discipline scolastiche si rivelarono utili a diffondere stereotipi relativi all’alterità razziale, fornendo in questo modo un contributo determinante alla formazione dell’immaginario coloniale nazionale. La presenza di una questione razziale all’interno della fonte storica considerata conferma la sua caratterizzazione costitutiva e non già semplicemente contingente dell’identità nazionale italiana, sopravvissuta all’abolizione delle leggi razziali e alla perdita delle colonie in seguito ai trattati di pace di Parigi del 1947.

Year: 2021

description: Families manage their financial resources before the economic recession. The current economic recession is already taking a toll on the family, particularly families in developing countries. The economic recession has impacted the family finances thereby creating challenges that may lead to family crises and instability. The enhancement of family financial resource management is a must for family survival. The general objective of the study was to investigate the financial resource management of the family in economic recession. Specifically, the study, identified how families managed their financial resources in the period of economic recession, determined the impact of economic recession on family financial resources. The area of the study was Kaduna State. The population consist the couple and their children. The sample of the study was made up of the couple and any child in the family that was not above 24 years. The sample size was 600 respondents selected from three Local Government Areas using systematic random sampling. Structured questionnaire was used for data collection and mean score was used for analysis. The result revealed that families enhance their financial support from children, family members, keeping livestock and return from pensions. It was further revealed that families manage their financial resources in economic recession through prudent financial plans, buying items in bulk and cutting down on luxury. The implication is that if families do not manage their family financial resources effectively during economic recession, they are likely to face the following challenges: Poverty, health problems, inability to afford basic amenities, lack of education or poor education, and emotional stress. Based on these findings, it was recommended among others that financial institutions should provide family with microfinance to enable them invest in their business. Entrepreneurship education and Home Economics should be made compulsory at all levels of Education in order to learn saleable skills that can enhance their finances and through these the impact of the financial challenges would be reduced.

MTT Webinar Slides
Global observations of clouds and precipitation are essential to improving prediction of severe weather having large impacts on humanity. For example, severe storms and tropical cyclones have caused more than $720 B of damage since 1980 in the U.S. alone. To understand processes in clouds that lead to rain, snow and other precipitation, global observations with rapid revisit times are essential. To this end, satellites in geostationary orbit (GEO) have greatly improved weather prediction by providing visible and infrared measurements on the 5-minute time scale. However, to peer inside of and study clouds and the onset of precipitation requires millimeter-wave sensors.

description: We investigate the relationship between the linewidths of broad Mg II \lambda2800 and Hbeta in active galactic nuclei (AGNs) to refine them as tools to estimate black hole (BH) masses. We perform a detailed spectral analysis of a large sample of AGNs at intermediate redshifts selected from the Sloan Digital Sky Survey, along with a smaller sample of archival ultraviolet spectra for nearby sources monitored with reverberation mapping. Careful attention is devoted to accurate spectral decomposition, especially in the treatment of narrow-line blending and Fe II contamination. We show that, contrary to popular belief, the velocity width of Mg II tends to be smaller than that of Hbeta, suggesting that the two species are not cospatial in the broad-line region. Using these findings and recently updated BH mass measurements from reverberation mapping, we present a new calibration of the empirical prescriptions for estimating virial BH masses for AGNs using the broad Mg II and Hbeta lines. We show that the BH masses derived from our new formalisms show subtle but important differences compared to some of the mass estimators currently used in the literature.

description: Riassunto – L’articolo sottolinea l’urgente necessità di riformare la formazione degli insegnanti di educazione fisica per affrontare le complesse intersezioni tra sport, cultura e identità. Lo sport è stato a lungo un veicolo per la trasmissione di ideologie capitalistiche e neoliberiste, che hanno un impatto significativo sulla società contemporanea e sul modo in cui percepiamo il “corpo sportivo”. Questo corpo è influenzato da una serie di ideologie, che vanno dal dominio maschile sul femminile, agli stereotipi etnici e di genere, all’eugenismo, alla commercializzazione e alla colonizzazione culturale. La formazione attuale degli insegnanti di educazione fisica spesso trascura un’analisi critica di questi temi, confluendo in un approccio pedagogico che impone identità “forti” piuttosto che celebrare la diversità. L’articolo sostiene che è fondamentale incorporare una comprensione profonda dell’apparato ideologico e pedagogico che governa la costruzione socioculturale del corpo sportivo nella formazione degli insegnanti. In conclusione, l’articolo propone principi pedagogici chiave per sviluppare un curricolo di formazione più critico ed emancipativo, suggerendo anche, a titolo di esempio, alcune attività critico-riflessive per gli insegnanti di educazione fisica.

description: Riassunto – L’articolo affronta il tema della costruzione di un ecosistema educativo diffuso e sostenibile a partire dalle cosiddette “piazze scolastiche”, ovvero degli spazi antistanti le scuole capaci - attraverso una chiara intenzionalità educativa - di connettere scuola, comunità sociale, territorio e agenzie territoriali, favorendo altresì la co-generazione di patti educativi comunitari. In tale prospettiva, la città e i suoi spazi diventano “aule didattiche diffuse” capaci di promuovere coesione sociale, scambio tra generazioni e innovazione didattica attraverso un continuum tra progettazione urbana, architettonica e pedagogica, tra educazione formale e territorio come spazio educativo informale. Costituire un sistema educativo diffuso significa, in sintesi, generare ambienti di apprendimento sostenibili in continuità tra scuola e contesto urbano in una logica osmotica e connettiva.

description: We report the detection of variable emission from Sgr A* in almost all wavelength bands (i.e. centimeter, millimeter, submillimeter, near-IR and X-rays) during a multi-wavelength observing campaign. Three new moderate flares are detected simultaneously in both near-IR and X-ray bands. The ratio of X-ray to near-IR flux in the flares is consistent with inverse Compton scattering of near-IR photons by submillimeter emitting relativistic particles which follow scaling relations obtained from size measurements of Sgr A*. We also find that the flare statistics in near-IR wavelengths is consistent with the probability of flare emission being inversely proportional to the flux. At millimeter wavelengths, the presence of flare emission at 43 GHz (7mm) using VLBA with milli-arcsecond spatial resolution indicates the first direct evidence that hourly time scale flares are localized within the inner 30$\times$70 Schwarzschild radii of Sgr A*. We also show several cross correlation plots between near-IR, millimeter and submillimeter light curves that collectively demonstrate the presence of time delays between the peaks of emission up to three hours. The evidence for time delays at millimeter and submillimeter wavelengths are consistent with the source of emission being optically thick initially followed by a transition to an optically thin regime. In particular, there is an intriguing correlation between the optically thin near-IR and X-ray flare and optically thick radio flare at 43 GHz that occurred on 2007 April 4. This would be the first evidence of a radio flare emission at 43 GHz delayed with respect to the near-IR and X-ray flare emission.

Character-level Transformer is implemented in the OpenNMT-py framework and is publicly available from an open code repository. The current implementation adds new encoder and decoder types conv_transformer with the following related arguments: a number of Highway layers (hw_layers), a pooling window size (conv_pooling),  a multiplier that controls a number of convolutions (n_conv) and a flag to use positional encoding after convolutions (conv_position_encoding).  As the implementation uses OpenNMT-py framework, see a documentation of the toolkit for more details.

description: We calculate the translational and rotational dynamics of a rigid particle undergoing inertial focusing in confined inertial ow of an incompressible Newtonian fluid. A particle in confined inertial ow will migrate toward an equilibriumposition dependent on the type off flow, the flow parameters, and the particle dimensions. We compute the trajectory of a particle using the lattice Boltzmann method, a computational fluids dynamics technique for modelingthe dynamics of a particle in Newtonian fluid governed by the Navier-Stokes equation. Our simulations determine the rotational and translational dynamics of the particle, from which we can quantify the equilibrium position andfocusing time. First, we calculate the inertial lift force on and migration of a circular cylinder in two-dimensional, confined shear flow at finite particle Reynolds number. A pitchfork bifurcation of the equilibrium position of the cylinder occurs beyond a critical particle Reynolds number, which is dependent on the confinement ratio of the particle. Below the critical Reynolds number, the circular cylinder migrates to a single stable equilibrium position at the center of the channel. After the bifurcation, there are three equilibriumpositions for the particle: two stable equilibrium positions equidistant from the center, and a single unstable equilibrium position at the center. Next, we extend our calculations to the migration of a spherical particle in confined, planar shear ow at finite particle Reynolds number. A pitchfork bifurcation of the equilibrium position of the sphere similarly occurs beyond a critical particle Reynolds number, again dependent on the confinement ratio of the particle. The bifurcation produces three equilibrium positions above the critical Reynolds number, with one unstable and two stable equilibrium positions. An external body force applied to the particle such as gravity can alter the bifurcation, creating an imperfect bifurcation or breaking the bifurcation altogether based on the magnitude of the external force. The sphere undergoes additional translational dynamics in time-dependent ow above the critical particle Reynolds number, inducing particle migration between the equilibrium position and the center of the channel. Finally, we calculate the inertial migration of a sphere and spheroid in steady and oscillatory Poiseuille ow. A sphere focuses at an equilibrium position primarily dependent on the channelReynolds number, with only a weak dependence on the period of oscillation of the ow. A spheroid only reaches a time-averaged equilibrium position, as the rotation of the particle induces additional transverse migration fromthe instantaneous orientation. The time-averaged equilibrium position of the spheroid is dependent upon the channel Reynolds number and the particle aspect ratio.
Excess vitamin A as a factor in alimentary cholesterolemia, blood coagulation and clot lysis in the chicken
Creators: name: Woodward, William Douglas Hiram
Publisher: name: University of British Columbia
Year: 2011

description: The physiological effects of excess vitamin A are frequently studied in the investigation of the systemic function of the vitamin. The liver vitamin A storage efficiency of dietary excesses of vitamin A and the effect of excesses of the vitamin on alimentary cholesterolemia, the one-stage prothrombin time and the one-stage euglobulin lysis time were investigated in several genetically distinct populations of chickens. Birds of a New Hampshire (NH) line were found to store vitamin A in the liver from the diet more efficiently than birds of three White Leghorn (WL) strains (D,K and B) and of one broiler strain. An excess of dietary vitamin A reduced alimentary cholesterolemia in the NH chicks but increased alimentary cholesterolemia in the D chicks. There was no effect of hypervitaminosis A on the blood cholesterol concentration of either the D or the NH chicks receiving a low-cholesterol diet. No carryover effect of vitamin A upon removal of the excessive quantity of the vitamin from the diet, could be demonstrated on alimentary cholesterolemia in either the D or the NH chicks. The efficiency of the intestinal absorption ofcholesterol was increased in both the NH and the D chicks by an excess of vitamin A. The liver-to-blood partition ratio of cholesterol was increased by excess vitamin A administration in the NH chicks, but was decreased by excess vitamin A in the D chicks. The one-stage prothrombin time of D,K,B, and NH chicks was unaffected by the dietary administration of large excesses of the vitamin from day-old to three weeks of age. Chicks of a Black Australorp (A) line, however, responded to large excesses of the vitamin in the diet with an increase in one-stage prothrombin time. A single intramuscular injection of menadione (5 mg/kg body weight) brought the prolonged prothrombin times of the A chicks to normal within twenty hours. The one-stage euglobulin lysis time of NH,D and A chicks was decreased by the inclusion of large excesses of vitamin A in the diet of the birds from day-old to six weeks of age. Intramuscular administration of menadione (5 mg/kg body weight) was without effect on the shortened lysis times within twenty-four hours. Removal of the excessive quantities of vitamin A from the diet for six weeks failed to affect the shortened clot lysis times of the A hypervitaminotic chicks. Vitamin K deficiency induced in a Shaver strain of WL chicks by feeding the birds a K-deficient diet, had no effect on the euglobulin lysis time. The results of the present experiments extend knowledge of the effects of hypervitaminosis A on the induction of alimentary cholesterolemia and on the blood coagulation mechanism in the chicken.

description: Vast majority of youths in developing economy are unemployed and street hawking is a succor to a great number of them for survival. Despite the vital role of street hawking in the livelihoods of youths in a recessed economy, its adverse implications on urban space and social well-being of the youths are too critical to overlook. This study, therefore, examines the implication of street hawking and causal factors motivating street hawking among youths in Sango-Ojoo axis of Ibadan. The study was a descriptive survey among 37 youths who were randomly sampled at potential hawking terminals along Sango-Ojoo road. Data was collected through the use of multiple choice questionnaires, and interview guide, while chi-square test was used in the data analysis. Findings revealed a preponderance of female youth hawkers who had attained secondary education. The causative factors motivating youths to hawk include; low level of education, household size, occupation of hawkers’ employers and income. The study further established a statistical significance between street hawking and vulnerability of the youths in human environments. The paper recommends sustainable policy through quality and affordable education to the poor, empowerment programme and habitual campaign on the dangers of street hawking to stem the scourge of hawking in Ibadan.

These requirements translate into higher frequencies and more stringent specifications of devices and systems; thus, the role of more accurate measurement is becoming more and more mandatory and complex. To improve the quality of the measurements, the proper traceability chain and uncertainty evaluation tools are fundamental not only at research level, but also in the production environments. From modelling verification to yield analysis, component specifications to production measurement, the knowledge of measurement uncertainty can change the entire ecosystem by providing a better understanding of the device under test and of the measurement system. This webinar addresses the modern tools and techniques to improve the accuracy and compute uncertainty for microwave measurement. The presentation spans from advanced calibration techniques to the most recent tools for real time uncertainty evaluation. Example are  provided for S-parameters and other microwave measurements.

description: Riassunto – L’articolo affronta il fenomeno della dispersione scolastica per cui una fascia sempre più ampia di giovani principalmente minorenni, abbandonano il percorso di istruzione scolastica o formazione professionale senza concludere gli studi secondari superiori. Vengono presentate le Scuole della Seconda Opportunità, come best practices di contrasto al fenomeno, assegnando particolare rilievo al progetto sperimentale Ricomincio da Tre, che, a partire dall’anno scolastico 2016-2017, prevede un percorso educativo di accompagnamento fortemente personalizzato. Integrando in rete le realtà scolastiche, extrascolastiche e il territorio e grazie alla sperimentazione di nuovi modelli di didattica, si creano condizioni facilitanti per il reinserimento scolastico o l’orientamento professionale e la realizzazione degli Early School Leavers, con l'obiettivo di favorirne la realizzazione personale e lavorativa oltre che lo sviluppo di competenze e l'esercizio dei diritti di cittadinanza.

description: This article provides an overview of the state-of-art results on communication resource allocation over space, time, and frequency for emerging cognitive radio (CR) wireless networks. Focusing on the interference-power/interference-temperature (IT) constraint approach for CRs to protect primary radio transmissions, many new and challenging problems regarding the design of CR systems are formulated, and some of the corresponding solutions are shown to be obtainable by restructuring some classic results known for traditional (non-CR) wireless networks. It is demonstrated that convex optimization plays an essential role in solving these problems, in a both rigorous and efficient way. Promising research directions on interference management for CR and other related multiuser communication systems are discussed.

“If I am to speak ten minutes, I need a week for preparation; if an hour, I am ready now.” Variants of this quote are attributed to several different historical figures, attesting to the perennial challenge of delivering concise (and meaningful) presentations.

Sadly, the typical technical presentation features slides are crammed with text, small images, dense tables, lengthy equations, and detailed flow diagrams, the oral delivery being rushed in a monotone, the speaker running out of whatever time is allotted, whether three minutes, 20 minutes, or 50 minutes. Clearly, only three minutes or less to present highly complex, technical material to an audience that is educated but not specialized in your field poses a special challenge. Indeed, it takes practice, awareness and empathy, particularly if your aim is to kindle surprise and curiosity, and make your audience actually want to hear more rather than less. This, for example, is what the Three Minute Thesis® (3MT®) Competition is all about.

2017 marks the inaugural IMS2017 3MT® Competition, proposed by Bandler and Kiley. Here, in three minutes or less, using only one static slide and no other props, contestants will deliver their prepared presentations to a panel of non-specialist judges, and will be ranked on how engaging, accessible, and compelling they made their presentations. Contestants who go over time are disqualified.

As we draw on our experiences with 3MT®, including aspects of organizing, mentoring and competing, our webinar addresses important topics in the art of effective live communication of complex technical material in language suited to a non-specialist audience. Much of what we discuss, however, is also applicable to specialist presentations designed for specialist audiences; for example: story-telling, trust, first impressions, citation, subtext, authenticity, articulation, etiquette, slide composition, respecting your audience, admitting setbacks, and more. As examples, we analyze and discuss 3MT® case studies from several disciplines and suggest tools and strategies to for you to deliver your most engaging talk ever!

title: Investigating the role of human umbilical mesenchymal stromal cells as therapies in a model of renal IRI in different mouse strains

description: Acute kidney injury (AKI), a common complication in hospitalised patients, has been associated with a high mortality rate as well as progression to chronic kidney disease and end-stage renal failure. AKI does not have a distinct pathophysiology as the disease can be brought about by different insults from nephrotoxicity and sepsis to surgical procedures. Regardless of the initial cause, AKI is characterised by a reduction in blood flow to the kidneys and subsequent hypoxia, processes which are associated with inflammation and immune system activation. Macrophages are highly versatile cells of the immune system, ubiquitous in all tissues, and have been identified to play a central role in both the injury phase and the subsequent resolution of inflammation in animal models of kidney disease. Despite recent advances in medical treatment, currently, there is no cure for AKI, and the disease is managed with fluid therapy, dialysis and ultimately, transplantation. 
Over the last two decades, extensive research done within the fields of regenerative medicine and pre-clinical research has proposed mesenchymal stromal cells (MSCs) as the main therapy for the treatment of various inflammatory diseases, including AKI. MSCs have become an attractive tool for cell-based therapies due to their potent immunosuppressive and immunomodulatory functions with effects on both innate and adaptive immune cells, including monocytes and macrophages. Nevertheless, the precise mode of action of these therapies is still largely unknown.
The work in this thesis aimed to characterise and compare the injury response to bilateral renal ischaemia-reperfusion injury (IRI), and on this basis, characterise and compare the regenerative response to cellular therapies following bilateral renal IRI in three different mouse strains. 
Throughout all the experiments within this thesis I have demonstrated that bilateral renal IRI leads to strain-dependent responses. I have employed a series of experiments that assessed renal function, weight, macrophage levels in kidneys and spleens, and cytokine levels in plasma and kidneys to characterise and compare the effect that bilateral renal IRI has on three different mouse strains – BALB/c, C56BL/6 albino and CD1. Importantly, the application of human umbilical cord (hUC) MSC therapies failed to result in an efficacious response in ameliorating kidney injury, regardless of mouse strain. Despite this observation, I was able to demonstrate that hUC-MSC treatment can marginally modulate macrophages in kidney and spleen, and influence cytokine levels in the kidney. However, these effects were not replicated across the three strains and displayed high inter-strain variability. Further work is required into the mode of action of MSCs so as to better replicate the results seen in pre-clinical studies and to translate these into the clinic.
Learning paths of students with migratory background: early school leaving and future selves

description: Abstract – Students with a migratory background represent a constantly growing segment of the Italian school population. Therefore, it is more pressing than every to highlight aspects of their particular vulnerability. The difficulties encountered by these students may be attributed to a set of factors that often place them in situations of risk of school failure. One aspect correlated with academic achievement and dropout is the concept of possible future self. Possible selves constitute the representation that people create of themselves in the future, thus embodying the personal expectations and goals they wish to achieve. Possible selves are socially constructed and can be modified depending on the contexts, by the experiences and opportunities encountered. Starting from these premises, this study aims to investigate factors that may affect the learning path of students with a migrant background, through using an exploratory survey with first and second secondary school degree students.

description: We describe the current status of CATS (astrophysical CATalogs Support system), a publicly accessible tool maintained at Special Astrophysical Observatory of the Russian Academy of Sciences (SAO RAS) (http://cats.sao.ru) allowing one to search hundreds of catalogs of astronomical objects discovered all along the electromagnetic spectrum. Our emphasis is mainly on catalogs of radio continuum sources observed from 10 MHz to 245 GHz, and secondly on catalogs of objects such as radio and active stars, X-ray binaries, planetary nebulae, HII regions, supernova remnants, pulsars, nearby and radio galaxies, AGN and quasars. CATS also includes the catalogs from the largest extragalactic surveys with non-radio waves. In 2008 CATS comprised a total of about 10e9 records from over 400 catalogs in the radio, IR, optical and X-ray windows, including most source catalogs deriving from observations with the Russian radio telescope RATAN-600. CATS offers several search tools through different ways of access, e.g. via web interface and e-mail. Since its creation in 1997 CATS has managed about 10,000 requests. Currently CATS is used by external users about 1500 times per day and since its opening to the public in 1997 has received about 4000 requests for its selection and matching tasks.
