El presente artículo plantea un modelo en el que se describe el proceso a través del cual el estrés psicosocia] puede inducir el desarrollo de la úlcera péptica duodenal (UPD) y los sistemas psicológicos, biológicos y sociales que se ponen alli en juego. Primero se analiza el papel de los sucesos vitales estresantes y del estrés percibido. Posteriormente se revisa cómo las estrategias de afrontamiento y la atribución causal del propio sujeto contribuyen a la UPD. Mas tarde se analiza cómo el estrés podría permitir que la bacteria H. Pylori se convierta en un agente patógeno, produciendo una actividad del ácido péptico y disminuyendo las defensas de la mucosa. Finalmente el artículo termina planteando relaciones entre UPD y nivel socio-económico.

Despite its ubiquity as the term, ‘student movements’ are not easy to build or sustain. This is because campus activism typically features a diversity of political views and tactical preferences, and is organisationally restricted by the constant turnover of graduating cohorts. This chapter uses the 2010/11 UK student protests to explore some of the challenges students face in building a wider student movement. United initially by a common grievance of rising tuition fees, students responded quickly with a multi-repertoire mass campaign. Yet its tactical breadth generated diverging collective experiences and identities, and once the fees were passed by Government these identities proved difficult to unite as an overarching movement.

The telecommunications industry has undergone major paradigm shifts in previous years. One of these is the shift from circuit-switched networks towards packet-switched networks. There is hardly any doubt that IP will be the ubiquitous transport protocol for multimedia of the future. At present, the work towards Internet telephony has attracted a lot of attention. Two standards have been developed: SIP (session initiation protocol) by the Internet Engineering Task Force (IETF) and H.323 by the International Telecommunications Union (ITU). The rapid deployment of services on top of SIP is hindered by a well known problem, feature interactions, also well known in traditional telephony networks. In this paper, the technological changes in SIP compared to the traditional telephony network are highlighted as well as the impact of the changed business environment. In a multi-service provider environment (as encouraged by a SIP environment), the feature interaction problem is regarded to be an even more pressing issue. Services of different providers from a multitude of service creators are likely to interwork. This in turn leads to the fact that the ad-hoc approaches to service interaction handling, commonly applied in the industry today, will not be sufficient any more. In this paper, a new approach addressing these changes is introduced and the results of a case study are presented

The four human IgG isotypes are highly conserved in amino acid sequence, but show differential ability to activate complement (C'): IgG3 and IgGl are very active. IgG2 is active under certain conditions, and IgG4 is inactive. Although the second constant domain (C,2) is critical for C' activation, the individual amino acids that confer isotype-specific activity have not been identified. We have generated a series of mutants between IgG2 and IgG3, resulting in the exchange of the four N-terminal and six C-terminal polymorphic residues within C"2. Mutants containing the N-terminus of the C,2 of IgG3 were as effective as wildtype IgG3 in Clq binding, Cl activation and terminal complex (MAC) formation, but had reduced ability to effect C/-mediated lysis. IgG2 and mutants containing the N-terminal portion of the CH2 of IgG2 were reduced compared to IgG3 in activating Cl, binding Clq and inducing assembly of the MAC, and were inactive in mediating lysis of target cells. Thus, the amino acid sequence differences in the N-terminus of C,,2 play a critical role in determining the relative abilities of IgG2 and IgG3 to bind Clq and activate the C' cascade although additional residues of C,2 must be involved in mediating optimal target cells lysis. The sequence of the N-terminus of C,2 was less critical in determining C4 and C3 binding. Characterization of domain exchange mutants suggests that intermediate steps may be partly dependent on domains other than C,2. IgGs that do not direct target cell lysis nevertheless activate intermediate steps in the pathway, which may contribute to immune complex-associated disorders. pi;, 1997 Elsevier Science Ltd.

We describe the design of a mobile collaborative tool that helps teams managing critical computing infrastructures in organizations, a task that is usually designated Business Continuity Management. The design process started with a requirements definition phase based on interviews with professional teams. The elicited requirements highlight four main concerns: collaboration support, knowledge management, team performance, and situation awareness. Based on these concerns, we developed a data model and tool supporting the collaborative update of Situation Matrixes. The matrixes aim to provide an integrated view of the operational and contextual conditions that frame critical events and inform the operators' responses to events. The paper provides results from our preliminary experiments with Situation Matrixes.

The appearances of agricultural  products are important indices for evaluating the quality of commodities and the characteristics of different varieties. In general, the appearances are evaluated by experts based on visual observations. However, the concern regarding this method is that it lacks objectivity, and it is not quantifiable because it depends greatly on an empirical knowledge. In addition, agricultural products have multiple appearance features; therefore, several of them need to be analyzed simultaneously for correct evaluation of the appearance. In this study, we developed a new image analysis system that can simultaneously evaluate multiple appearance characteristics such as the color, shape and size, of agricultural products in detail. To evaluate the effectiveness of this system, we conducted quality evaluations and cultivar identification on the basis of cluster analysis, multidimensional scaling and discriminant analysis of the appearance characteristics. The results of the cluster analysis revealed that strawberries could be classified on the basis of their appearance characteristics. Furthermore, we were able to visualize the small differences in the appearance of the fruit based on multiple characteristics on a two-dimensional surface by performing multidimensional scaling. The results demonstrate that our system is effective for qualitative evaluations of the appearance of strawberries. The results of the discriminant analysis revealed that the accuracy of strawberry cultivar classification using 14 cultivars was <42%, when only single feature was used. However, the rate increased to 68% after combining the three features. These results indicate that our system exploits the advantage of analyzing multiple appearance characteristics.

B lymphopoiesis is a differentiation process in which hematopoietic stem cells are converted into antibody-producing plasma cells. B cell differentiation involves multiple steps, including cell specification, commitment to the B cell lineage, immunoglobulin rearrangements, maturation of B cells and terminal differentiation into plasma cells. Each of these steps is controlled by signaling pathways and transcription factors that act in synergy, feedback-loops or cross-antagonism to generate complex regulatory networks that allow for plasticity and stability of B cell differentiation.

Within days of the Singapore parliamentary election in May 2011, Lee Kuan Yew and Goh Chok Tong announced that they had decided to leave the nation's Cabinet, where they had been serving as "Minister Mentor" and "Senior Minister," positions created for them as former Prime Ministers. 2 The reason was that the People's Action Party (PAP), which Lee Kuan Yew had founded with others in the 1950s and which had governed the nation since its separation

Background: It has been previously demonstrated that the enzyme α-l-iduronidase (IDUA) of patients with MPS I shows a different biochemical behavior in each of the three clinical forms of these. In heterozygotes, its biochemical behavior has been recently established in leukocyte and plasma samples, demonstrating that it is possible to distinguish individuals heterozygous for MPS I within an unselected population.

This paper reconstructs GDP from the output side for medieval and early modern Britain. In contrast to the long run stagnation of living standards suggested by daily real wage rates, output-based GDP per capita exhibits modest but positive trend growth. One way of reconciling the two series is through variation in the annual number of days worked, but there are also reasons to doubt the representativeness of the sharp rise and fall of daily real wage rates in the late middle ages, which creates the impression of no trend improvement of living standards.

MUVIS is a series of CBIR systems. The first one has been developed in late 90s to support indexing and retrieval in large image databases using visual and semantic features such as color, texture and shape. During recent years, MUVIS has been reformed to become a PC-based framework, which supports indexing, browsing and querying of various multimedia types such as audio, video, audio/video interlaced and several image formats. MUVIS system allows real-time audio and video capturing, encoding by last generation ...

The (h, k)-coloring problem, better known as the L(h, k)-labelling problem, is that of vertex coloring an undirected graph with non-negative integers so that adjacent vertices receive colors that differ by at least h and vertices of distance 2 receive colors that differ by at least k. We give tight approximations for this problem on general graphs and on bipartite graphs

The bacterium Helicobacter pylori is the main agent causing gastroduodenal pathologies in humans. The infection with this microorganism is efficaciously treated with a combination of two antibiotics and one anti-acid, although, the appearance of strains resisting the antibiotics used in therapies, is the principal factor conducting to therapeutic failures. In this study, PCR amplifications and sequence analysis of the entire rdxA gene and a fragment of the ARNr16S gene were done to detect mutations involved in metronidazol and tetracycline resistance, respectively. H. pylori strains isolated from gastric biopsies of thirty seven Cuban dyspeptic patients belonging to Centro de Investigaciones Médico Quirúrgicas hospital were analyzed. The rdxA sequencing analysis rendered 12 strains (32.4 %) with mutations that confer metronidazol resistance, another four strains (10.8 %) with mutations that have been associated to this resistance and seven more (18.9 %) with stop codons, not reporte...

The long-term foetal surveillance is often to be recommended. Hence, the fully non-invasive acoustic recording, through maternal abdomen, represents a valuable alternative to the ultrasonic cardiotocography. Unfortunately, the recorded heart sound signal is heavily loaded by noise, thus the determination of the foetal heart rate raises serious signal processing issues. In this paper, we present a new algorithm for foetal heart rate estimation from foetal phonocardiographic recordings. A filtering is employed as a first step of the algorithm to reduce the background noise. A block for first heart sounds enhancing is then used to further reduce other components of foetal heart sound signals. A complex logic block, guided by a number of rules concerning foetal heart beat regularity, is proposed as a successive block, for the detection of most probable first heart sounds from several candidates. A final block is used for exact first heart sound timing and in turn foetal heart rate estimation. Filtering and enhancing blocks are actually implemented by means of different techniques, so that different processing paths are proposed. Furthermore, a reliability index is introduced to quantify the consistency of the estimated foetal heart rate and, based on statistic parameters; [,] a software quality index is designed to indicate the most reliable analysis procedure (that is, combining the best processing path and the most accurate time mark of the first heart sound, provides the lowest estimation errors). The algorithm performances have been tested on phonocardiographic signals recorded in a local gynaecology private practice from a sample group of about 50 pregnant women. Phonocardiographic signals have been recorded simultaneously to ultrasonic cardiotocographic signals in order to compare the two foetal heart rate series (the one estimated by our algorithm and the other provided by cardiotocographic device). Our results show that the proposed algorithm, in particular some analysis procedures, provides reliable foetal heart rate signals, very close to the reference cardiotocographic recordings.

In this paper we introduce two procedures for variable selection in cluster analysis and classification rules. One is mainly oriented to detect the "noisy" non-informative variables, while the other deals also with multicolinearity. A forward-backward algorithm is also proposed to make feasible these procedures in large data sets. A small simulation is performed and some real data examples are analyzed.

The abstraction reaction of D adatoms by H atoms have been investigated on the Si(110) surfaces. The direct abstraction to form HD molecules obeys a second-order rate law in D coverage θ D . On the other hand, the indirect abstraction to form D 2 molecules obeys a fourth-order rate law in θ D . In addition to the direct abstarction, indirect abstraction to form HD molecules is also included due to piled H adatoms during H exposure. It is found that the indirect abstraction is promoted on the surfaces saturated with dideuterides, suggesting that dideuterides (dihydrides) play a significant role in the indirect abstraction paths. The kinetics of the abstraction reactions on the Si(110) surfaces look similar to those on the Si(100) surface. However, the delayed D 2 desorption exhibits time profiles different from those on the Si(100) surfaces.

The practice of management, although quite recent, embodies one of the major challenges for planning sustainable historic cities. Environmental, climatic, social and cultural issues affecting historic contexts, make management a fundamental process in balancing sustainable development and heritage conservation over time. In this framework, the rOcK-Regeneration and Optimisation of Cultural heritage in creative and Knowledge cities-project (h2020, n. 730280) aims at developing cultural heritage-led regeneration strategies capable of ensuring streams of long-lasting structured actions after the end of the project. Involving 10 European cities under the coordination of the municipality of Bologna with the core scientific support of the University of Bologna, this project is designing a long-term management tool and testing its innovative pathway across the EU. Thus, this paper will focus on the genesis, construction and implementation of the rOcK Integrated management Plan (ImP) as vital toolkit for developing, over time, sustainable urban procedures in the historic cities focused on the essential role of tangible and intangible heritage. Based on the UNEScO management Plans, the existing literature and on several international reference experiences, rOcK ImP embeds the research-action-research methodology that underlies the whole project. following this innovative circular approach, a preliminary set of goals and actions were selected (research), then implemented trough pilot interventions, co-designed and co-created with local administrations, stakeholders and citizens (action), and finally updated, considering the impacts of the performed actions to recalibrate the process and build scenarios for the ImP (research). as it is an ongoing process, this paper will appraise its state of the art, highlighting the potential and criticalities and describing what has been done in the city of Bologna so far.

The aim of this study was to examine production and health of fast-growing broilers fed diets with and without hemp seed cake (HSC) in organic broiler production. Two diets, a control diet (C) and a diet including HSC (H), were fed to 1200 Ross 308 chickens which were divided over 8 pens. Birds were housed indoors until 21 d, and thereafter kept in the same groups in two chicken houses with access to outdoor pasture up to slaughter at 70 d. Production performance was registered weekly. The number of Clostridium perfringens (C. perfringens) in caeca, as well as leg and foot health and carcass quality was registered during the study period or at slaughter. Total mortality was high regardless of diet due to a short heat wave extreme for Swedish conditions which predominantly affected the heavy male broilers. The inclusion of HSC did not affect total production performance or mortality. Furthermore, no effect of HSC inclusion in the feed was seen on the number of C. perfringens in the caeca. There were differences in litter condition and foot health of birds, which may have been related to the high crude fibre (CF) content of the H diet.

eds., Evolution and the human mind: Language, modularity and meta-cognition. Cambridge U.P. 2000, pp 218-237 0. where I'm going The theme of this chapter is that some seemingly arcane philosophers' disputes about the nature of rationality are relevant to questions about the evolution of strategic thinking in our species. By strategic thinking I mean, roughly, the kinds of cognitive processes that an agent uses in order to choose an action or a strategy in a situation involving other agents, taking account of the fact that the others are also choosing acts or strategies in the light of the same factors.
