Published: December 2014

Abstract
Recently we can see the trend of introducing a new instrumentation and automatization in the field of information and monitoring systems for the meteorology, hydrology and crisis centers. Nowadays a great number of sensors are used in projects in many countries of various climates. Therefore it is crucial to deeply understand how the change of sensor types will affect the accuracy of measurements and how is accuracy of individual sensor type affected by different weather conditions.
We analyzed several screen/shields and rain gauges at the premises of faculty of Meteorology and Climatology of FMFI UK. On the basis of our results we can recommend as a most accurate and not depending on weather condition artificially ventilated screen although it is the most expensive. Our second choice would be a large naturally ventilated shield. In case of Stevenson screens we would recommend painting it with a high gloss coating. Our last choice would be a small naturally ventilated screen because of its high sensitivity to the global radiation.
Our first choice of the participating rain gauges would be the weighing rain gauge because of its best results in both cases, of rainfalls up to 2 mm and also over 2 mm. The tipping bucket rain gauge gave also agreeable result in both cases. The optical sensor gave very good results in rainfalls over 2 mm but it is unsuitable for rainfalls up to 2 mm. The radar sensor is also completely unsuitable for low intensity rainfalls and his performance for rainfalls over 2 mm was just average.

Abstract
An organization's environmental performance is affected by its suppliers' environmental performance, and selecting green suppliers is a strategic decision in order to be more competitive in today's global market. By developing green movement across the globe, organizations are under pressure to reduce the emissions across their supply chain. Formerly the food production systems was oriented and optimized to satisfy economic demands and the nutritional needs of a rapidly growing world population. The food production industry requires large inputs of resources and causes several negative environmental effects. In recent years, environment factors rapidly emerging as an important issue for decision makers in food industries.
This study identifies best supplier in holistic perspective for edible oil production, and proposes a hybrid model using Delphi method and Green Data Envelopment Analysis (GDEA). Delphi method identifies the main criteria influenced in supplier selection process based on opinion of company purchase experts. GDEA evaluates the overall performances of suppliers and choose green supplier. Proposed hybrid model applied to a well-known company who produce edible oil (palm, soybean and olive oil) to evaluate green suppliers (among 13 main potential suppliers). Delphi questionnaire included 17 factors which were from financial, services, qualitative and environmental factors. The factors with the highest Delphi score (raw material price, quality, delivery and carbon footprint) entered in DEA model and high efficiency suppliers selected. Results showed that the most efficient raw oil suppliers of company are: S4 among soybean oil suppliers, P1 among palm oil suppliers and O3 among olive oil suppliers. Also palm oil not only has fewer price and carbon footprint but also the highest mean efficiency.

Published: December 2014

Abstract
This article extends the former results concerning the routing flow-shop problem to minimize the makespan on the case with buffers, non-zero ready times and different speeds of machines. The corresponding combinatorial optimization problem is formulated. The exact as well as four heuristic solution algorithms are presented. The branch and bound approach is applied for the former one. The heuristic algorithms employ known constructive idea proposed for the former version of the problem as well as the Tabu Search metaheuristics. Moreover, the improvement procedure is proposed to enhance the quality of both heuristic algorithms. The conducted simulation experiments allow evaluating all algorithms. Firstly, the heuristic algorithms are compared with the exact one for small instances of the problem in terms of the criterion and execution times. Then, for larger instances, the heuristic algorithms are mutually compared. The case study regarding the maintenance of software products, given in the final part of the paper, illustrates the possibility to apply the results for real-world manufacturing systems.
Differentiating Criteria for High-Tech Companies

Published: December 2014

Abstract
Manufacturing companies operating within the high-technology sector are of interest to science, industry and national authorities because of the special economic importance attached to them. However, in order to investigate the condition of those companies, support their growth and monitor the effects of the aid awarded to them, it is first necessary to properly identify the business entities belonging to that sector. To identify the entities belonging to the high-technology industry, it is necessary to perform a sequence of activities which form the procedural algorithm. Usefulness of the algorithm has been verified using the example of a group of Warsaw high-tech companies which were subject to investigation under the European project Warsaw Entrepreneurship Forum. The algorithm could be used as the basis for the implementation of an IT tool for the identification and description of high-tech businesses.
Probabilistic Fuzzy Approach to Evaluation of Logistics Service Effectiveness
Authors: Rudnik Katarzyna , Pisz Iwona 
Published: December 2014

Abstract
Logistics service providers offer a whole or partial logistics business service over a certain time period. Between such companies, the effectiveness of specific logistics services can vary. Logistics service providers seek the effective performance of logistics service. The purpose of this paper is to present a new approach for the evaluation of logistics service effectiveness, along with a specific computer system implementing the proposed approach – a sophisticated inference system, an extension of the Mamdani probabilistic fuzzy system. The paper presents specific knowledge concerning the relationships between effectiveness indicators in the form of fuzzy rules which contain marginal and conditional probabilities of fuzzy events. An inference diagram is also shown. A family of Yager's parameterized t-norms is proposed as inference operators. It facilitates the optimization of system parameters and enables flexible adjustment of the system to empirical data. A case study was used to illustrate the new approach for the evaluation of logistics service effectiveness. The approach is demonstrated on logistics services in a logistics company. We deem the analysis of a probabilistic fuzzy knowledge base to be useful for the evaluation of effectiveness of logistics services in a logistics company over a given time period.

Published: December 2014

AbstractThis study investigated leaf mesophyll cells of Caryophyllaceae plants growing in polar regions – Cerastium alpinum and Silene involucrata from the Hornsund region of Spitsbergen island (Svalbard Archipelago, Arctic), and Colobanthus quitensis from the Admiralty Bay region on King George Island (South Shetland Islands, West Antarctic). Ultrastructural changes were analyzed in mesophyll protoplasts of plants growing in natural Arctic and Antarctic habitats and plants grown in a greenhouse, including plants exposed to short-term cold stress under semi-controlled conditions. Cell organelles of plants growing in natural polar habitats and greenhouse-grown plants were characterized by significant morphological plasticity. Chloroplasts of plants studied in this work formed variously shaped protrusions and invaginations that visibly increased the contact area between adjacent cell compartments and reduced the distance between organelles. S. involucrata plants grown under greenhouse conditions, tested by us in this work, were characterized by highly dynamic cell nuclei with single or multiple invaginations of the nuclear membrane and the presence of channels and cisternae filled with cytoplasm and organelles. Crystalline inclusion proteins were observed in the cell nuclei of C. quitensis between nuclear membranes and in the direct proximity of heterochromatin. Our study revealed significant conformational dynamics of organelles, manifested by variations in the optical density of matrices, membranes and envelopes, in particular in C. quitensis, which could suggest that the analyzed Caryophyllaceae taxa are well adapted to severe climate and changing conditions in polar regions.

Abstract
The aim of this paper is to address the dilemmas of the paediatric surgeon when facing an isolated, unilateral, congenital hydronephrosis and discuss the strategic options for the management of this condition.
Congenital hydronephrosis, the most commonly diagnosed uropathy in children, is usually a benign and self-resolving condition. Nonobstructive hydronephrosis does not require operative treatment, while timely treatment is imperative for obstructive hydronephrosis before significant renal damage ensues. Managing congenital hydronephrosis is a challenging task.
Thirty-two children with unilateral, isolated hydronephrosis and nonobstructed renography curves were followed up for 3 years.
On the initial evaluation according to the grade of hydronephrosis: 22.6% were grade I, 54.8% grade II and 22.6% grade III. After 12 months of follow-up: 30% were grade I, 51.5% grade II and 18.5% grade III, respectively. After the three-year follow-up, there were no hydroneproses greater than grade II. The mean value of the separate GFR of the affected kidney at initial evaluation was 42.83%, and 40.33% after three years. In three children the treatment was converted from conservative to surgical. Nonobstructive, congenital hydronephrosis is a benign condition not requiring any medical treatment, but aggressive observation is indicated.

Published: December 2014

Abstract
Even from the distant past the aesthetic perception in an individual was diminished by the presence of gap between the central incisors. This condition is found under the term “dents du bonheur” or “lucky teeth” and is encountered even among world famous figures including Brigitte Bardot, Eliah Wood, Madonna, Zac Efron, Amy Winehouse and Elton John. The teeth gaps are still considered main reasons for dissatisfaction of the dental patients and reasons for the requirement of aesthetic treatment.
The purpose of this study is to exhibit the influence of the etiological factors in the occurrence of dia-stema mediana classified according to the dominance of their occurrence expressed in percentage values. Materials of this investigation were 100 patients with diastema mediana from the following factors: inheritance, disproportion in the dental arches, inborn or acquired missing teeth, harmful oral habits, high insertion of the labial frenulum as well as mesiodens. After the diagnosis and evaluation of the etiological factor for diastema mediana was performed, a decision regarding the course of treatment was made in direction of the removal of the etiological factor at an early age and orthodontic treatment. The end of the orthodontic treatment in a group of the patients was the beginning of prosthodontic reconstruction.
From our clinical investigation we came to the realization that in 49 patients (49%) the hereditary influence was a dominant factor, next followed disproportions and discrepancies in the dental arch in 14 (14%), inborn or acquired missing teeth in 11 patients (11%), harmful oral habits in 10 (10%), high frenulum insertion in 4 (4%), and pathological objects between central incisors, mesiodens, iatrogenic factors and periodontal disease, in 3 of the clinical cases (3%) each.
We concluded that the occurrence of diastema mediana is multi-causal. The dominant place is occupied by the hereditary factors. With regard to the mutual relationship between the multitudes of factors in the occurrence of diastema mediana, the diagnosis should be made conciliary and the clinical treatment should be interdisciplinary including a prosthodontist, orthodontist and oral surgeon.
La décision comme production d'ordre dans les organisations
Authors: Laroche Hervé 
Published: December 2014

À la critique de la rationalité des décisions dans les organisations s’est adjointe, plus récemment, une critique de leur centralité. Cependant, si l’analyse de l’action dans les organisations peut se dispenser du recours au concept de décision, les pratiques ordinaires en restent profondément imprégnées. En particulier, c’est à travers les notions de décision et de décideur que les membres des organisations interprètent ce qui se passe et ce à quoi ils participent. L’article propose une conception de la décision comme représentation sociale et en distingue trois dimensions : un moment (ponctuation), un contenu (discours), et un processus (modalités de production). Cette conception permet de rendre compte de la place que tient la décision dans les pratiques et de l’analyser comme productrice d’ordre organisationnel, dans le sens où elle constitue un support important de la construction permanente d’interactions entre les membres de l’organisation.
Fin des temps et nouveaux départs
Authors: Piot Charles , Lachenal Guillaume , Mbodj-Pouye Aïssatou 
Published: December 2014

Cet essai explore le cas d’un système financier de Ponzi qui a défrayé la chronique à Lomé en 2010 (puis à nouveau en 2012-2013), phénomène qui condense une grande partie des désirs et des imaginaires culturels caractéristiques du moment contemporain. Machine à espoir – il s’appelait ReDéMare – cette pyramide de Ponzi tirait sa force d’un effondrement des valeurs, sur le plan à la fois économique et politique, tout en cherchant à transformer un présent sans issue (et un passé sordide) en un futur miraculeux. Bien qu’orienté vers l’avenir, le phénomène ReDéMare témoigne aussi d’un désir pour un temps où les choses étaient plus certaines et prévisibles – un temps où les fonctionnaires recevaient leurs salaires avec régularité, où les faux ne courraient pas les rues, où le rançonnement de chacun par tous n’était pas la règle. Désir de conjuguer le passé au futur, pourrait-on dire.
Les Heures perdues de Pierre Barthès, une chronique privée au xviii e siècle
Authors: Soula Mathieu 
Published: December 2014

Cette recherche entend éclairer la trajectoire d’un chroniqueur privé, Pierre Barthès, maître écrivain à Toulouse, qui tient un journal retraçant des éléments de sa vie et des événements publics survenus à Toulouse entre 1737 et 1781. Véritable source souvent mobilisée par des historiens de la société toulousaine du xviii e siècle, l’auteur reste malgré tout largement inconnu, tout comme restent dans l’ombre les raisons de la tenue de ce journal. Or, pour mieux comprendre et utiliser cette source si riche, il convient au préalable d’analyser les fonctions et usages de cette chronique privée, mises en perspective par l’étude de la trajectoire sociale et familiale de son auteur. Il s’agit donc, ici, de comprendre la chronique par le chroniqueur, de l’expliquer par les usages que cette forme autorise, et donc de la replacer dans son contexte de production et de circulation pour en révéler, autant que possible, les enjeux et fonctions qui lui sont propres.
Télévision et personnalisation politique en Italie (1954-1994)
Authors: Brizzi Riccardo 
Published: December 2014

This article reconstructs the relationship between television and politics in Italy from the beginning of broadcasting (January 1954) to the arrival of Silvio Berlusconi on the Italian political scene and his first electoral victory in 1994. Through a careful study of the compared dimension the author shows how Italy seemed to move away from the main Western democracies in the context of an increasing mediatisation of the public scene. Even though the development of media, and particularly of television, was comparable to other European countries and, basically, similar to France, the image of politician in Italy has been hidden for a long time behind the slogans and symbols of the parties that remained the undisputed rulers of the public and electoral scene in the 60’s and 70’s. However, a meaningful evolution – analysed by the author through the transformations of media as well as the disruption of the institutional and partisan context – occurred from the 80’s. The article shows the new and radical hallmark of this evolution which allowed Italy not only to make up lost time in respect to the other European countries, but also to rapidly assert itself as pioneer in the field of political mediatization and personalization. In 1994, the “descent into the political arena” and electoral victory of Silvio Berlusconi – owner of a media empire who used television as a trampoline to launch himself into the national political competition and uncontested leader of a personal and media-centred party such as Forza Italia – represent the synthesis and peak of a previously unseen process of symbiosis between politics and television that no other country experienced in such an intensive way.
Le légitimisme, parent pauvre de l'historiographie ?
Authors: Dupont Alexandre 
Published: December 2014

Le légitimisme, culture politique majeure du xix e siècle français, a connu un destin assez contrasté dans l’historiographie depuis cent-cinquante ans. Longtemps restée l’apanage d’historiens contre-révolutionnaires qui prétendaient faire de leurs ouvrages des plaidoyers pro domo , l’histoire du légitimisme a connu un double renouveau, dans les années 1950 avec les premières études d’histoire politique sur ce courant, et dans les années 1970 avec les grandes monographies régionales d’histoire sociale. Les années 1980 ont vu les études sur cette famille politique se diversifier, dans le sillage des grands débats historiographiques sur la Révolution française, avec de nombreux apports, notamment en histoire religieuse. Aujourd’hui, l’historiographie reste encore lacunaire sur des pans entiers de l’évolution de ce mouvement, notamment pendant la Deuxième République et le Second Empire. Pourtant, elle est en même temps à la pointe des renouvellements méthodologiques et produit d’excellentes études sur l’histoire culturelle et religieuse de ce mouvement ou encore sur ses liens avec les autres partis légitimistes européens et son internationalisme.

Abstract
Deletion of genes encoding the E26 transformation-specific transcription factors PU.1 and Spi-B in B cells (CD19-CreΔPB mice) leads to impaired B cell development, followed by B cell acute lymphoblastic leukemia at 100% incidence and with a median survival of 21 wk. However, little is known about the target genes that explain leukemogenesis in these mice. In this study we found that immature B cells were altered in frequency in the bone marrow of preleukemic CD19-CreΔPB mice. Enriched pro–B cells from CD19-CreΔPB mice induced disease upon transplantation, suggesting that these were leukemia-initiating cells. Bone marrow cells from preleukemic CD19-CreΔPB mice had increased responsiveness to IL-7 and could proliferate indefinitely in response to this cytokine. Bruton tyrosine kinase (BTK), a negative regulator of IL-7 signaling, was reduced in preleukemic and leukemic CD19-CreΔPB cells compared with controls. Induction of PU.1 expression in cultured CD19-CreΔPB pro–B cell lines induced Btk expression, followed by reduced STAT5 phosphorylation and early apoptosis. PU.1 and Spi-B regulated Btk directly as shown by chromatin immunoprecipitation analysis. Ectopic expression of BTK was sufficient to induce apoptosis in cultured pro–B cells. In summary, these results suggest that PU.1 and Spi-B activate Btk to oppose IL-7 responsiveness in developing B cells.

Purpose This study aimed to determine whether a controlled portal blood arterialization by a liver extracorporeal device (L.E.O2 NARDO) is effective in treating acute hepatic failure (AHF) induced through CCl4 administration in a swine model. Methods 20 swines with AHF induced by intraperitoneal injection of carbon tetrachloride (CCl4) in oil solution, were randomly divided into two groups: animals receiving L.E.O2 NARDO treatment 48 h after the intoxication (study group); animals sham operated 48 h after the intoxication (control group). Blood was withdrawn from the iliac artery and reversed in the portal venous system by an interposed extracorporeal device. Each treatment lasted 6 h. The survival was assessed at 5 days after L.E.O2 NARDO treatment or sham operation. In both groups blood samples were collected for biochemical analysis at different time points and liver biopsies were collected 48 h after intoxication and at sacrifice. Results We observed decreased transaminases levels and a more rapid INR recovery in the study group, as compared to the control group. Eight animals of the study group vs. two animals of the control group survived at five days after surgery with a statistically significant difference (p<0.05). Liver biopsies performed at sacrifice showed a reduction of the damaged hepatic areas in the study group as compared to the control group. Conclusions Arterial blood supply in the portal system through the L.E.O2 NARDO device is easily applicable, efficacious, and safe in a swine model of AHF induced by CCl4 intoxication.
