Differentiability and ApproximateDifferentiability for Intrinsic LipschitzFunctions in Carnot Groups and a RademacherTheorem
Authors: Franchi Bruno , Marchi Marco , Serapioni Raul Paolo
Published: December 2014

A Carnot group G is a connected, simply connected, nilpotent Lie group with stratified Lie algebra.We study intrinsic Lipschitz graphs and intrinsic differentiable graphs within Carnot groups. Both seem to bethe natural analogues inside Carnot groups of the corresponding Euclidean notions. Here ‘natural’ is meantto stress that the intrinsic notions depend only on the structure of the algebra of G. We prove that one codimensionalintrinsic Lipschitz graphs are sets with locally finite G-perimeter. From this a Rademacher’s typetheorem for one codimensional graphs in a general class of groups is proved.
Riemannian Polyhedra and Liouville-Type Theorems for Harmonic Maps
Authors: Sinaei Zahra
Published: December 2014

This paper is a study of harmonic maps fromRiemannian polyhedra to locally non-positively curvedgeodesic spaces in the sense of Alexandrov. We prove Liouville-type theorems for subharmonic functionsand harmonic maps under two different assumptions on the source space. First we prove the analogue ofthe Schoen-Yau Theorem on a complete pseudomanifolds with non-negative Ricci curvature. Then we study2-parabolic admissible Riemannian polyhedra and prove some vanishing results on them.
A Monograph of the Polish Oxfordian Echinoids: Part 2, Subclass Euechinoidea Bronn, 1860
Authors: Radwańska Urszula
Published: December 2014

The non-cidaroid echinoids (subclass Euechinoidea Bronn, 1860) from the Oxfordian epicontinental sequence of Poland (Polish Jura, Holy Cross Mountains, Mid-Polish Anticlinorium) are assigned to the genera Hemipedina Wright, 1855, Hemicidaris L. Agassiz, 1838, Hemitiaris Pomel, 1883, Pseudocidaris Étallon, 1859, Stomechinus Desor, 1856, Eucosmus L. Agassiz in Agassiz and Desor, 1846, Glypticus L. Agassiz, 1840, Pleurodiadema de Loriol, 1870, Diplopodia McCoy, 1848, Trochotiara Lambert, 1901, Desorella Cotteau, 1855, and Heterocidaris Cotteau, 1860, plus one acropeltid taxon, and one taxon left in open nomenclature.

Within the genus Hemicidaris L. Agassiz, 1838, the relationship between Hemicidaris intermedia (Fleming, 1828), Hemicidaris crenularis L. Agassiz, 1839 [non Lamarck, nec Goldfuss] and Hemicidaris quenstedti Mérian, 1855, all with confused taxonomy, is discussed.

Based on test structure, the genera Polydiadema Lambert, 1883, and Trochotiara Lambert, 1901, of the family Emiratiidae Ali, 1990, are proved to be separate; the common species mamillana of F.A. Roemer (1836) is a typical Trochotiara.

An attention is paid to the morphology of the tiny, juvenile specimens, common in Eucosmus decoratus L. Agassiz in L. Agassiz and Desor, 1846, and in Pleurodiadema stutzi (Moesch, 1867).

Published: December 2014

Study aim: the objective was to assess and compare the energy expenditure (EE) and exercise heart rate (EHR) during Nordic Walking (NW), and conventional walking (W) in physical education and tourism/recreation university students.

Material and methods: a total of 53 women and 65 men, students at the Academy of Physical Education in Katowice, and Polytechnic in Opole, in Poland, were investigated to assess the EE of Nordic Walking and conventional walking, and to measure the EHR, a uniaxial accelerometer – Caltrac Monitor, and a pulsometer – Polar RS 400 SD were used. After a standard warm-up, the participants (joined group) were marching with poles for 30 minutes, at a speed regulated by the group’s leader, who used footpod’s indications: 5.5–6.5 km/h – in Katowice, and 7.5–8.5 km/h – in Opole. After a break, during which the participants’ heart rate decreased below 100 bpm, the above actions and measurements were repeated, during normal walking.

Results: energy expenditure during Nordic Walking (EE NW), expressed in kcals and METs, was in women and in men, at both analyzed speeds, significantly higher (p < 0.05) than during conventional walking (EE W). EHR was higher during NW, compared to W, and the statistically significant differences were revealed both in female’s and male’s groups.

Conclusions: our study data have shown that EE and EHR during Nordic Walking, have been significantly higher than during conventional walking, regardless of the moving speed and gender. NW might present a useful modality in prevention of hypokinetic disorders.
Internal Rot Detection with the Use of Low-Frequency Flaw Detector
Authors: Proskórnicki Marek , Ligus Grzegorz
Published: December 2014

The issue of rot detection in standing timber or stocked wood is very important in forest management. Rot flaw detection used for that purpose is represented by invasive and non-invasive devices. Non-invasive devices are very accurate, but due to the cost and complicated operation they have not been applied on a large scale in forest management. Taking into account the practical needs of foresters a prototype of low-frequency flaw was developed. The principle of its operation is based on the difference in acoustic wave propagation in sound wood and wood with rot.

Authors: Bartoková Ivana , Kl’ocová Monika , Bartok Juraj
Published: December 2014

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.

Authors: Banaeian Narges , Nielsen Izabela Ewa , Mobli Hossein , Omid Mahmoud
Published: December 2014

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.
Routing Flow-Shop with Buffers and Ready Times – Comparison of Selected Solution Algorithms
Authors: Józefczyk Jerzy , Markowski Michał , Balgabaeva Ljazat
Published: December 2014

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
Authors: Rostek Katarzyna , Skala Agnieszka
Published: December 2014

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

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.

Authors: Giełwanowska Irena , Pastorczyk Marta , Lisowska Maja , Węgrzyn Michał , Górecki Ryszard J.
Published: December 2014

This 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.

Published: December 2014

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.
The Influence of Etiological Factors in the Occurence of Diastema Mediana
Authors: Kapusevska Biljana , Dereban Nikola , Zabokova-Bilbilova Efka , Popovska Mirjana
Published: December 2014

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.
Role of Body-Worn Movement Monitor Technology for Balance and Gait Rehabilitation
Authors: Horak Fay , King Laurie , Mancini Martina
Published: December 2014

This perspective article will discuss the potential role of body-worn movement monitors for balance and gait assessment and treatment in rehabilitation. Recent advances in inexpensive, wireless sensor technology and smart devices are resulting in an explosion of miniature, portable sensors that can quickly and accurately quantify body motion. Practical and useful movement monitoring systems are now becoming available. It is critical that therapists understand the potential advantages and limitations of such emerging technology. One important advantage of obtaining objective measures of balance and gait from body-worn sensors is impairment-level metrics characterizing how and why functional performance of balance and gait activities are impaired. Therapy can then be focused on the specific physiological reasons for difficulty in walking or balancing during specific tasks. A second advantage of using technology to measure balance and gait behavior is the increased sensitivity of the balance and gait measures to document mild disability and change with rehabilitation. A third advantage of measuring movement, such as postural sway and gait characteristics, with body-worn sensors is the opportunity for immediate biofeedback provided to patients that can focus attention and enhance performance. In the future, body-worn sensors may allow therapists to perform telerehabilitation to monitor compliance with home exercise programs and the quality of their natural mobility in the community. Therapists need technological systems that are quick to use and provide actionable information and useful reports for their patients and referring physicians. Therapists should look for systems that provide measures that have been validated with respect to gold standard accuracy and to clinically relevant outcomes such as fall risk and severity of disability.
Afebrile meningoencephalitis with transient central facial paralysis due to Toscana virus infection, south-eastern France, 2014

Published: December 2014

We report a case of meningoencephalitis caused by Toscana virus (TOSV) with central facial paralysis lasting over two days acquired in south-eastern France. The patient was not febrile either before or during the course of the disease. The diagnosis was established by both real-time RT-PCR and virus isolation with complete genome sequencing. This case emphasises the need to consider TOSV in non-febrile neurological syndromes in people living in or having travelled to the Mediterranean area.

Toscana virus (TOSV), transmitted by phlebotomine sandflies, is recognised as one of the most important causes of viral meningitis in summer in Mediterranean countries. A surveillance plan based on both human and entomological surveys was started in 2010 in the Emilia-Romagna region, Italy. Clinical samples from patients with neurological manifestations were collected during 2010 to 2012. The surveillance protocol was improved during these years, allowing the detection of 65 human infections. Most of these infections were recorded in hilly areas, where sandflies reach the highest density. Entomological sampling around the homes of the patients resulted in a low number of captured sandflies, while later sampling in a hilly area with high number of human cases (n=21) resulted in a larger number of captured sandflies. Using this approach, 25,653 sandflies were sampled, of which there were 21,157 females, which were sorted into 287 pools. TOSV RNA was detected by real-time PCR in 33 of the pools. The results highlighted the role of Phlebotomus perfiliewi as the main vector of TOSV and a potential link between vector density and virus circulation. This integrated system shows that an interdisciplinary approach improves the sensitiveness and effectiveness of health surveillance.

Dramatizing Intimate Femicide: Petitions, Plays, and Public Engagement (with a Shakespearean Gloss)
Authors: Howe Adrian
Published: December 2014

This article discusses the author’s current research project, an arts-based cultural intervention designed to shock audiences into registering intimate femicide as a first-order political problem in Western societies. Based on cases retrieved over the years from the English case law and recent cases unearthed by the most prolific of a new wave of feminist anti-violence bloggers, the project is pitched as an early educational intervention. A series of interactive learning modules in the form of theatre performances for schools invites young people to query the continuing legal and cultural salience of men’s excuses for killing “their” women. Shakespeare’s many problematizations of possessive jealousy in men are enlisted to help highlight the long shadow that historically mandated male possessory rights over women still cast over criminal trials. The author argues for the continuing value of Foucauldian genealogies conceived as “counter-memories” for anti-violence feminist work. A case study of a specifically feminist forgetting of what is at stake in the representation and response to “family violence” cases underlines the magnitude of the task of shifting sympathy from perpetrators to victims.

Memantine is a non-competitive antagonist of the N-methyl-D-aspartate (NMDA) receptor, and is an approved drug for the treatment of moderate-to-severe Alzheimer’s disease. We identified a mouse strain with a naturally occurring mutation and an ataxic phenotype that presents with severe leg cramps. To investigate the phenotypes of these mutant mice, we screened several phenotype-modulating drugs and found that memantine (10 mg/kg) disrupted the sense of balance in the mutants. Moreover, the mutant mice showed an attenuated optokinetic response (OKR) and impaired OKR learning, which was also observed in wild-type mice treated with memantine. Microsatellite analyses indicated that the Grid2 gene-deletion is responsible for these phenotypes. Patch-clamp analysis showed a relatively small change in NMDA-dependent current in cultured granule cells from Grid2 gene-deleted mice, suggesting that GRID2 is important for correct NMDA receptor function. In general, NMDA receptors are activated after the activation of non-NMDA receptors, such as AMPA receptors, and AMPA receptor dysregulation also occurs in Grid2 mutant mice. Indeed, the AMPA treatment enhanced memantine susceptibility in wild-type mice, which was indicated by balance sense and OKR impairments. The present study explores a new role for GRID2 and highlights the adverse effects of memantine in different genetic backgrounds.

Published: December 2014

Water quality of the Jansen Lagoon (São Luís, Maranhão State, Brazil) was assessed through histological biomarkers and microbiological parameters. To this end, 29 fish specimens (11 Centropomus undecimalis and 18 Sardinella sp) and eight water samples were collected during the rainy and dry periods of 2013. The lagoon water showed thermotolerant coliform indices above the limit set forth in CONAMA Resolution 357/2005. Histological changes observed in the gills were: lifting of the respiratory epithelium, hyperplasia of the lamellar epithelium, incomplete and complete fusion of several lamellae, disorganization of the lamellae, congestion of blood vessels, aneurysms, hypertrophy of the respiratory epithelium, hemorrhage and rupture of the lamellar epithelium and parasite. The histological alteration index (HAI) average value to Sardinella sp was 31.8 and to C. undecimalis was 22.2. The average HAI value in both species corresponds to category 21–50, with tissue injuries being classified from moderate to severe. The presence of histological injuries and the HAI values indicate that the fish sampled from the Jansen Lagoon are reacting to non-specific xenobiotics present at the site.
Looked at Life from Both Sides Now

Published: December 2014

As the molecular top–down causality emerging through comparative genomics is combined with the bottom–up dynamic chemical networks of biochemistry, the molecular symbiotic relationships driving growth of the tree of life becomes strikingly apparent. These symbioses can be mutualistic or parasitic across many levels, but most foundational is the complex and intricate mutualism of nucleic acids and proteins known as the central dogma of biological information flow. This unification of digital and analog molecular information within a common chemical network enables processing of the vast amounts of information necessary for cellular life. Here we consider the molecular information pathways of these dynamic biopolymer networks from the perspective of their evolution and use that perspective to inform and constrain pathways for the construction of mutualistic polymers.
Assessing Agreement between miRNA Microarray Platforms
Authors: Bassani Niccolò , Ambrogi Federico , Biganzoli Elia
Published: December 2014

Over the last few years, miRNA microarray platforms have provided great insights into the biological mechanisms underlying the onset and development of several diseases. However, only a few studies have evaluated the concordance between different microarray platforms using methods that took into account measurement error in the data. In this work, we propose the use of a modified version of the Bland–Altman plot to assess agreement between microarray platforms. To this aim, two samples, one renal tumor cell line and a pool of 20 different human normal tissues, were profiled using three different miRNA platforms (Affymetrix, Agilent, Illumina) on triplicate arrays. Intra-platform reliability was assessed by calculating pair-wise concordance correlation coefficients (CCC) between technical replicates and overall concordance correlation coefficient (OCCC) with bootstrap percentile confidence intervals, which revealed moderate-to-good repeatability of all platforms for both samples. Modified Bland–Altman analysis revealed good patterns of concordance for Agilent and Illumina, whereas Affymetrix showed poor-to-moderate agreement for both samples considered. The proposed method is useful to assess agreement between array platforms by modifying the original Bland–Altman plot to let it account for measurement error and bias correction and can be used to assess patterns of concordance between other kinds of arrays other than miRNA microarrays.
Chemically Synthesized Glycosides of Hydroxylated Flavylium Ions as Suitable Models of Anthocyanins: Binding to Iron Ions and Human Serum Albumin, Antioxidant Activity in Model Gastric Conditions
Authors: Al Bittar Sheiraz , Mora Nathalie , Loonis Michèle , Dangles Olivier
Published: December 2014

Polyhydroxylated flavylium ions, such as 3',4',7-trihydroxyflavylium chloride (P1) and its more water-soluble 7-O-β-d-glucopyranoside (P2), are readily accessible by chemical synthesis and suitable models of natural anthocyanins in terms of color and species distribution in aqueous solution. Owing to their catechol B-ring, they rapidly bind FeIII, weakly interact with FeII and promote its autoxidation to FeIII. Both pigments inhibit heme-induced lipid peroxidation in mildly acidic conditions (a model of postprandial oxidative stress in the stomach), the colorless (chalcone) forms being more potent than the colored forms. Finally, P1 and P2 are moderate ligands of human serum albumin (HSA), their likely carrier in the blood circulation, with chalcones having a higher affinity for HSA than the corresponding colored forms.
Quantitative Analysis of Cereulide Toxin from Bacillus cereus in Rice and Pasta Using Synthetic Cereulide Standard and 13C6-Cereulide Standard—A Short Validation Study
Authors: Zuberovic Muratovic Aida , Tröger Rikard , Granelli Kristina , Hellenäs Karl-Erik
Published: December 2014

A single laboratory validation study of a rapid and sensitive quantitative method for the analysis of cereulide toxin produced by Bacillus cereus using ultra high performance liquid chromatography-electrospray-tandem mass spectrometry is presented. The analysis of this cyclic peptide toxin was validated for pasta and rice samples using a newly presented synthetic cereulide peptide standard, together with 13C6-cereulide that previously have not been commercially available. The use of cereulide standard was also compared to the most frequently used surrogate standard, the antibiotic valinomycin. The performance of the method was evaluated by analyzing spiked sample pools from different types of rice and pasta, as well as 21 individual rice and pasta samples from differently prepared meals. Inoculation of samples with three cereulide toxin-producing strains of Bacillus cereus was finally used to mimic naturally contaminated foods. The quantification range of the method was 1–500 ng/g (R2 = 0.999) and the limits of detection and quantification were 0.1 and 1 ng/g, respectively. The precision varied from 3% to 7% relative standard deviation and the trueness from −2% to +6% relative bias at different concentration levels in cooked rice and pasta.

La vallée de Freissinières est propice au déclenchement de crues torrentielles. Ces crues torrentielles sont caractérisées par un fonctionnement en embâcle / débâcle. Ce fonctionnement s 'explique par l 'importante fourniture de débris depuis les versants, plus particulièrement par la disponibilité des sources de sédiments glaciaires et paraglaciaires.
Riziculture irriguée et développement durable dans la vallée de l'Amou (Togo). (Irrigated rice growing and rural development in the Amou valley of Togo)
Authors: Abotchi Tchégnon
Published: December 2014

La vallée de l'Amou au Togo a été l'objet entre 1967 et 1984 d'une opération de vulgarisation de la riziculture irriguée, conduite par la coopération chinoise. Cet article évoque les origines et les différentes étapes de la réalisation de ce projet, et analyse ensuite ses conséquences surtout socio-économiques. Il apparaît que la culture irriguée du riz a permis dans les années 1970 un accroissement massif des rendements, de la production du riz et des revenus des agriculteurs, et une élévation générale du niveau de vie. Mais elle a sombré à partir du milieu des années 1980 en raison de la défaillance du système d'encadrement, surtout postchinois, et de l'absence de formation des riziculteurs à l'usage, à la gestion et à la réparation des matériels de travail et du système d'irrigation.

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.
Surveillance, répression et construction collective de l'insécurité en Érythrée
Authors: Bozzini David
Published: December 2014

Cet article aborde la question de la production de l’insécurité ressentie par les conscrits en Érythrée ainsi que les stratégies que ces derniers développent pour évaluer les risques qu’ils encourent. Au-delà des dysfonctionnements institutionnels de la surveillance et de la répression policière, les stratégies pour décrypter l’arbitraire étatique renforcent le sentiment d’insécurité et forgent la représentation d’un État omniscient. Ces logiques, qui catalysent les peurs, la suspicion, et favorisent la délation, représentent le modus operandi despotique qui caractérise un État policier en Afrique, imposant des limites aux relations de confiance entre les individus.
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.
A Study on the Luminescent Properties and Energy Transfer of Na2BaMgP2O8:Tb3+, Eu3+ Phosphor
Authors: Chen Yu Jie , Han Feng Lan , Luo Zhao
Published: December 2014

Na2BaMgP2O8phosphors were synthesized by a standard solid state reaction and their luminescent properties were investigated. The phase structure was analyzed by X-ray powder diffraction measurement. Under the excitation of 365nm, Na2BaMgP2O8:Tb3+, Eu3+phosphors show two color bands of green and red color due to5D4−7F5transition of Tb3+ions and5D0−7F2transition of Eu3+ions, respectively. The emission intensity of Tb3+deceased with the increasing concentration of Eu3+, which verified that an effective energy transfer occurred from Tb3+to Eu3+in Na2BaMgP2O8host. The present study indicated that the phosphors have a high potential application in solid state lighting.
