A Consistency Evaluation and Calibration Method for Piezoelectric Transmitters
Authors: Zhang Kai , Tan Baohai , Liu Xianping
Published: April 2017

Array transducer and transducer combination technologies are evolving rapidly. While adapting transmitter combination technologies, the parameter consistencies between each transmitter are extremely important because they can determine a combined effort directly. This study presents a consistency evaluation and calibration method for piezoelectric transmitters by using impedance analyzers. Firstly, electronic parameters of transmitters that can be measured by impedance analyzers are introduced. A variety of transmitter acoustic energies that are caused by these parameter differences are then analyzed and certified and, thereafter, transmitter consistency is evaluated. Lastly, based on the evaluations, consistency can be calibrated by changing the corresponding excitation voltage. Acoustic experiments show that this method accurately evaluates and calibrates transducer consistencies, and is easy to realize.

Finding the Missing Link between Corporate Social Responsibility and Firm Competitiveness through Social Capital: A Business Ecosystem Perspective
Authors: Joo Jaehun , Eom Mike , Shin Matthew
Published: April 2017

There are existing studies that successfully show the impact of corporate social responsibility (CSR) on firms’ financial performance. However, limited attention is paid to its impact on the business ecosystem. CSR could be seen as an investment for building a sustainable business ecosystem, which enhances the competitiveness of this system’s members. In that context, this study apprehends and captures the virtuous cycle of firm competitiveness. On analyzing data from interviews with seven firms, the study offers four propositions identifying the structure of the virtuous cycle linking CSR activities to firm competitiveness through the accumulation of social capital within business ecosystems. Based on those propositions, the study offers new insights into CSR research for academics and strategic planning guidelines for managers that integrate social and economic values for a sustainable business ecosystem and firm competitiveness.
Algal Bioproductivity in Turbulent Water: An Experimental Study
Authors: San Lei , Long Tianyu , Liu Clark.
Published: April 2017

Excessive growth of biomass causes eutrophication and other related water quality problems. For the past several decades, these problems have been managed based on the principle of limiting nutrient, which is to reduce the loading of essential nutrients—either nitrogen or phosphorus—through point and non-point waste source control. More recent research efforts indicated that eutrophication of a natural water body such as a lake or a reservoir can be controlled alternatively by altering its turbulent intensity. The success of this alternative approach depends on more knowledge on the intimate relationship between turbulent intensity and the bioproductivity of a water body. In this experimental study, an oscillating grid turbulence (OGT) reactor was constructed to evaluate the effect of turbulent pulsation strength in terms of vibration frequency on algae bioproductivity under adequate nutrient, light, and temperature conditions. Experimental results showed that moderate turbulent intensity with vibration frequency of 0.5 Hz or less increased algal growth; with a vibration frequency of 1.0 Hz, the observed peak chlorophyll a (Chl-a) concentration in the reactor was 0.112 mg/L. The experimental results also showed that strong turbulent intensity with vibration frequency of 1.5 Hz or more reduced algal growth; with vibration frequency of 1.5 Hz, the observed peak Chl-a concentration in the reactor was only 0.06 mg/L, which was even lower than the observed peak Chl-a concentration in the reactor with stationary water. In this study, the effect of water turbulence on algal bioproductivity was further verified with experimental data on the variations of other relevant water quality parameters in the OGT reactor including total nitrogen (TN), total phosphorus (TP), pH, and dissolved oxygen (DO).
A New Device for Pressure Control and Energy Recovery in Water Distribution Networks
Authors: Sinagra Marco , Sammartano Vincenzo , Morreale Gabriele , Tucciarelli Tullio
Published: April 2017

The potential energy of the water in Water Distribution Networks (WDNs) usually exceeds the amount needed for delivery and consumption and, at the present time, it is mainly dissipated through Pressure Reducing Valves (PRVs) or Open Water Tanks. The present study suggests the use of a new energy-producing device, a Cross-flow turbine with positive outlet pressure named PRS (Power Recovery System), which can provide the same service as PRVs and water tanks, with additional significant hydropower production. After a short presentation of the PRS, the management rules of the proposed device are laid out, according to two possible modes. In the ‘passive’ mode, the piezometric level downstream of the turbine is fixed at the sought after value, in the ‘active’ mode, the discharge is regulated according to the required value. The design criterion is then presented, based on a simple relationship linking dimensionless numbers. A PRS is finally designed for a typical water distribution network, serving the city of Palermo (Italy). The resulting cost-benefit analysis is compared with a similar one carried out in previous work for a regulation system based on the use of a Pump As Turbine (PAT). The comparison shows the improvement obtained by the use of the PRS, consisting of higher energy production, as well as lower construction and installation costs.
Reconstruction of 12-lead ECG Using a Single-patch Device
Authors: Lee Hong J. , Lee Dong S. , Kwon Hyun B. , Kim Do Y. , Park Kwang S.
Published: April 2017

Objectives: The aim of this study is to develop an optimal electrode system in the form of a small and wearable single-patch ECG monitoring device that allows for the faithful reconstruction of the standard 12-lead ECG.

Methods: The optimized universal electrode positions on the chest and the personalized transformation matrix were determined using linear regression as well as artificial neural networks (ANNs). A total of 24 combinations of 4 neighboring electrodes on 35 channels were evaluated on 19 subjects. Moreover, we analyzed combinations of three electrodes within the four-electrode combination with the best performance.

Results: The mean correlation coefficients were all higher than 0.95 in the case of the ANN method for the combinations of four neighboring electrodes. The reconstructions obtained using the three and four sensing electrodes showed no significant differences. The reconstructed 12-lead ECG obtained using the ANN method is better than that using the MLR method. Therefore, three sensing electrodes and one ground electrode (forming a square) placed below the clavicle on the left were determined to be suitable for ensuring good reconstruction performance.

Conclusions: Since the interelectrode distance was determined to be 5 cm, the suggested approach can be implemented in a single-patch device, which should allow for the continuous monitoring of the standard 12-lead ECG without requiring limb contact, both in daily life and in clinical practice.
Near-field surface plasmon field enhancement induced by rippled surfaces
Authors: D’Acunto Mario , Fuso Francesco , Micheletto Ruggero , Naruse Makoto , Tantussi Francesco , Allegrini Maria
Published: April 2017

The occurrence of plasmon resonances on metallic nanometer-scale structures is an intrinsically nanoscale phenomenon, given that the two resonance conditions (i.e., negative dielectric permittivity and large free-space wavelength in comparison with system dimensions) are realized at the same time on the nanoscale. Resonances on surface metallic nanostructures are often experimentally found by probing the structures under investigation with radiation of various frequencies following a trial-and-error method. A general technique for the tuning of these resonances is highly desirable. In this paper we address the issue of the role of local surface patterns in the tuning of these resonances as a function of wavelength and electric field polarization. The effect of nanoscale roughness on the surface plasmon polaritons of randomly patterned gold films is numerically investigated. The field enhancement and relation to specific roughness patterns is analyzed, producing many different realizations of rippled surfaces. We demonstrate that irregular patterns act as metal–dielectric–metal local nanogaps (cavities) for the resonant plasmonic field. In turn, the numerical results are compared to experimental data obtained via aperture scanning near-field optical microscopy.
Scientific Performance of a Nano-satellite MeV Telescope
Authors: Lucchetta Giulio , Berlato Francesco , Rando Riccardo , Bastieri Denis , Urso Giorgio
Published: April 2017

Over the past two decades, both X-ray and gamma-ray astronomy have experienced great progress. However, the region of the electromagnetic spectrum around ∼1 MeV is not so thoroughly explored. Future medium-sized gamma-ray telescopes will fill this gap in observations. As the timescale for the development and launch of a medium-class mission is ∼10 years, with substantial costs, we propose a different approach for the immediate future. In this paper, we evaluate the viability of a much smaller and cheaper detector: a nano-satellite Compton telescope, based on the CubeSat architecture. The scientific performance of this telescope would be well below that of the instrument expected for the future larger missions; however, via simulations, we estimate that such a compact telescope will achieve a performance similar to that of COMPTEL.

The High Ecliptic Latitude (HiLat) extension of the Canada–France Ecliptic Plane Survey (CFEPS), conducted from 2006 June to 2009 July, discovered a set of Trans-Neptunian objects (TNOs) that we report here. The HiLat component was designed to address one of the shortcomings of ecliptic surveys (like CFEPS), their low sensitivity to high-inclination objects. We searched 701 deg2 of sky ranging from 12° to 85° ecliptic latitude and discovered 24 TNOs, with inclinations between 15° and 104°. This survey places a very strong constraint on the inclination distribution of the hot component of the classical Kuiper Belt, ruling out any possibility of a large intrinsic fraction of highly inclined orbits. Using the parameterization of Brown, the HiLat sample combined with CFEPS imposes a width 14° ≤ σ ≤ 15.°5, with a best match for σ = 14.°5. HiLat discovered the first retrograde TNO, 2008 KV42, with an almost polar orbit with inclination 104°, and (418993) = 2009 MS9, a scattering object with perihelion in the region of Saturn’s influence, with a ∼ 400 au and i = 68°.
Les outils d’évaluation en ergothérapie chez l’enfant de 0 à 6 ans Quelles spécificités ?
Authors: Yanez Isabelle , Vauvillé-Chagnard Barbara
Published: April 2017

L’ergothérapeute travaillant auprès de jeunes enfants âgés de 0 à 6 ans dispose d’une palette d’outils d’évaluation variés, l’objectif des évaluations étant de réaliser un diagnostic ergothérapique des compétences de l’enfant, plus spécifiquement dans les domaines neuromoteurs et instrumentaux (fonctions gnosiques et praxiques). Nous aborderons tout d’abord quelques réflexions autour de l’évaluation du jeune enfant, des modèles conceptuels et des approches qui guident notre démarche. Nous présenterons ensuite la spécificité de l’évaluation de l’ergothérapeute au sein de l’équipe pluridisciplinaire. Nous verrons comment le partenariat avec les parents est primordial. Nous développerons les outils de l’évaluation : en premier lieu, les entretiens avec les parents pour amorcer la relation thérapeutique, puis l’observation de l’enfant en situation écologique, moyen incontournable pour le comprendre dans sa singularité, et enfin l’évaluation détaillée des troubles neuromoteurs et des troubles instrumentaux. À la suite de quoi, nous illustrerons notre propos avec la présentation de l’évaluation initiale de deux jeunes enfants suivis en camsp et en halte-garderie spécialisée.

L’accompagnement en ergothérapie de l’apprentissage du graphisme et de l’écriture
Authors: Lefévère-Renard Gwenaëlle
Published: April 2017

Lorsque les troubles d’un enfant ont des répercussions sur une partie de ses activités de vie quotidienne, il n’est pas rare que les composantes du graphisme et de l’écriture soient impactées, le graphisme et l’écriture nécessitant l’intégrité de nombreuses fonctions motrices et cognitives. L’ergothérapeute accompagne alors l’enfant, ses parents, son entourage scolaire et éducatif dans la recherche des causes de cette « mauvaise écriture », dans leur explication, dans la rééducation et l’adaptation de l’environnement matériel et pédagogique. Deux types d’approches conceptuelles se combinent pour favoriser une meilleure intégration de la thérapie : l’approche basée sur les déficits et celle basée sur l’activité en elle-même. Cette combinaison permet d’avoir un résultat adéquat sur l’amélioration du graphisme et de l’écriture mais aussi sur d’autres activités de vie quotidienne dont les composantes de base sont impactées par les mêmes fragilités de l’enfant.

Authors: Décamps Aurélien , Barbat Guillaume
Published: April 2017

Cet article s'intéresse aux formes de gouvernance territoriale durable appliquées aux Services Publics de l’Eau et de l’Assainissement ( Spea ). Dans un contexte de mutation des Spea , historiquement localisés et fortement impactés par les enjeux de durabilité, l'analyse questionne l’influence de la composition des territoires sur les formes de gouvernance des Spea et l’adaptation des entreprises délégataires à ces enjeux. Une cartographie de la diversité des territoires est réalisée à l’échelle de quatre départements (Charente, Charente-Maritime, Dordogne et Gironde) en mobilisant les outils de l'analyse factorielle. Le croisement des profils de territoires et des caractéristiques des Spea permet de relier la composition du territoire à la forme et aux modalités d’organisation des Spea , et de mettre à jour des positionnements différenciés de la part des entreprises délégataires qui sont interprétés comme une volonté d’ancrage territorial de la part de ces entreprises.

Cet article propose une analyse historique du processus de verrouillage du système agroalimentaire en défaveur des légumineuses à graines, à l’aune des théories évolutionnistes. Plusieurs mécanismes d’autorenforcement permettent de comprendre pourquoi ces espèces sont de moins en moins cultivées en France face à un système agro-industriel qui s’est spécialisé en faveur des céréales, favorisant à l’amont l’usage d’engrais azotés de synthèse et limitant à l’aval les investissements pour les légumineuses en alimentation humaine. Cet article s’interroge alors sur les perspectives de déverrouillage.

Authors: Abou El-Seoud Samir , Alja'am Jihad , Mwinyi Masoud
Published: April 2017

This paper presents an innovative technological solution to improve the understanding and cognitive functions of children with intellectual disability through multimedia. New algorithms that mine the story-based scripts, rank their sentences, extract keywords and match them with multimedia have been proposed in our previous work. They are integrated in the proposed system and being assessed over 50 stories for children. The results showed that the children concentration and refection are highly improved using multimedia. The system is fully dynamic and support the personalized learning. Instructors can focus on the main ideas of the story which are extracted automatically and use then images and clips to explain them. The words and images are stored in a corpus which is enriched continuously. Every new story taught will add new information to the corpus and to every children dataset. Parents can review the tutorials used in school with their children at home. The system contributes to the reintegration of children with intellectual disability into the society and break their marginalization and isolation.

Multicriteria Model to Sort Suppliers in a Brazilian Dairy Industry
Authors: Silva Ana Maria Rodrigues , Sobral Marcos Felipe Falcao
Published: April 2017

This paper describes a real application of a multicriteria decision aid to sort suppliers in the Brazilian dairy industry located in Serra Talhada City. This region is very arid, and farmers have difficulty maintaining the quality required for dairy production. Five criteria were identified by the dairy farmers: production capacity, product quality, cost, transportation and distance from the manufacturing site. The most appropriate method was chosen to sort clients with respect to the preferred structure of the decision maker to obtain the parameters. This study involved eight milk suppliers that were allocated into three ordinated classes. No supplier was allocated into the best class (very good), five were considered regular, and three were inadequate. The use of multicriteria modeling enabled the decision maker to establish a new metric to evaluate suppliers while simultaneously considering multiple criteria.
Essentialities of Digital Technology Incorporation in Research Tasks by Agro-Researchers in the Southwest Nigerian Farming Zone
Authors: Lawal-Adebowale Okanlade Adesokan
Published: April 2017

The study examined the incorporation of digital technologies in the Nigerian agricultural research system and showed that digital technologies such as digital balance, digital pH meter, phone sensors, and the Global Positioning System (GPS) and the Geographic Information System (GIS), among others, had a high rate of incorporation in agro-research activities in the southwest farming zone of Nigeria. Determinants of such incorporation in agro-research activities were accuracy of data collection, enhancement of research task execution, improvement of research quality, usage convenience and portability of the devices, convenience of usage for data storage, and ease of data retrieval. The Spearman rho correlation test showed a significant correlation between the use of digital oven and its ready availability/accessibility (r = 0.168); digital pH meter and convenient of data storage on the device (r = 0.157); Spectrophotometer and convenient of data storage (r = -0.161); phone sensors and ready availability/accessibility of the device (r = 0.156); use of GPS/GIS and convenience of usage of the devices (r = -0.173) at p<0.05 level. It concluded that only a few of the digital technologies were readily incorporated in research activities by the Nigerian agro-researchers. It was also recommended that application of digital devices in agro-research activities should be intensified for agro-research development in the country.

Published: April 2017

There is a rapid increase of mass demonstrations in different locations worldwide triggered by social networks discussions, as witnessed in the USA, Egypt, and South Africa. This paper challenges the underutilization of social media to detect people's' mood and to predict their actions based on their sentiments. Recent published work has demonstrated utility of sentiments on Twitter to predict outcomes of different events, so to come up with the geographical action prediction tool the authors utilized geocodes, sentiment analysis, probability theory, and logistic regression. The tool informs relevant authorities like governments to know the state of people's moods. Entities like business enterprises also benefit from this tool in their plans, especially in avoiding unnecessary costs due to infrastructure destruction.
The Challenges of Using Zero-Rating (Free Basics) for Addressing the Affordability of ICT Access in Developing Countries.
Authors: Walubengo John N. , Takavarasha Jr Sam
Published: April 2017

As the body of evidence on the usefulness of Information and Communication Technologies (ICT) for poverty reduction and development continues to grow, mobile network operators (MNOs), development agencies, and regulators are employing various measures to increase universal access. These measures are motivated by corporate social responsibility, pro-poor ideologies, and regulatory requirements imposed by regulators. While regulators have employed price controls and infrastructure sharing, MNOs have employed free basics to provide internet access to those who could not afford it. The introduction of free basics seems plausible, but it is fraught with implementation challenges. This article discusses such challenges with a view to clarifying how the steps taken to foster affordability affect the conflicting interests of different stakeholders on the ICT data and voice eco-system.

When we speak about the future we speak about megatrends, about the vision, predictions or scenarious. Major global forces taking shape today will significantly impact the business landscape for the private sector until 2030. Some of these are known to us: population ageing and the resulting expected tightness on the labor market. The results revealed that the demands that society and the environment will increasingly place on the company's business strategy.
Transferability of Voice Communication in Games to Virtual Teams Training for Crisis Management
Authors: Rudinsky Jan , Hvannberg Ebba Thora
Published: April 2017

A crisis is an emergency event that can lead to multiple injuries and damage to property or environment. Proper training of crisis management personnel is vital for reducing the impact of a major incident. In search for knowledge on how best to implement communication for virtual environments for training, communication in online games was studied. Findings on voice communication in online games were researched and formulated as a set of statements. By asking participants in an empirical study of crisis management, the statements were either confirmed or refuted. Results show that multiplayer games are highly similar to the requirements for crisis management training in virtual environments. Approximately two-thirds of the statements proved coherent in both domains. The practical significance of this work lies in the provision of design implications for a virtual environment for crisis management training. Thus, this paper contributes to demonstrating the transferability between these domains. Finally, the paper reflects the results in theories of communication and engagement.
UVC Light for Antifouling
Authors: Salters Bart , Piola Richard
Published: April 2017

AbstractBiofouling, the accumulation of biomass on submerged surfaces, has been a problem in the marine world for centuries. On the hull of ships, it creates an increase in drag, it can block water inlets for cooling or firefighting operations, and it can severely reduce
the efficiency of heat exchangers. Because of this, many different technologies are in use. However, most of them have severe drawbacks, such as pollution of the environment, or a limited effectiveness when the object is stationary in the water.In this article, we present a novel approach,
based on the use of ultraviolet (UV) light, to keep surfaces free from biofouling. The fundamental idea is to have a type of coating, which emits light outward from the surface. Experimental trials have been conducted with test samples in a number of environments, ranging from a test aquarium
to open waters in various places around the world. The results are very consistent; surfaces are kept completely free from fouling for prolonged periods, regardless of location or circumstances. This is achieved at very low power levels at the surface, in the order of 1 mW of UV light per
square meter.It is concluded that the fundamental principle of emitting UV light outward from a surface is a successful and promising new approach, which can possibly be applied on many different surfaces in many different application areas.
Florida Inlets and Intertidal Biofouling Communities

Published: April 2017

AbstractThis study reports on the identity and coverage of rocky intertidal species in the major inlets of Florida’s Atlantic coast. From north to south, these inlets are Fort George, St. Augustine, Ponce De Leon, Port Canaveral, Sebastian, Fort Pierce, Jupiter, Lake Worth, Boca Raton, Port Everglades, Baker’s Haulover, and Port of Miami. Dominant coverage in the southerly inlets included star corals (Siderastrea radians,62% Port of Miami), ribbed barnacles (Tetraclita stalactifera, 18% Port Everglades), and zoanthid corals (Palythoasp., 40% Baker’s Haulover). In the north, the community shifted and species absent in the south became common (e.g., eastern oystersCrassostrea virginica, 9% Fort George, 15% St. Augustine; the macroalgaEnteromorpha lactuca, 10% Fort George, 17% Sebastian Inlet). The invasive bryozoanBugula neritinawas always present north of the Port of Miami and was a major community component north of Port Everglades (e.g., 27% Fort Pierce Inlet and 22% Ponce de Leon Inlet). Correlations between intertidal populations and environmental indicators included the oysterC. virginicawith various sea surface temperature (SST) parameters (e.g., inverse correlations with max SST,R2= 0.81,p= .038). Likewise, the coralline algaPneophyllum fragilewas correlated with various SST parameters (e.g., min SST,R2= 0.51,p= .020). Bare rock andB. neritinaboth showed inverse correlations with the human population of inlet drainage basins (R2= 0.28,p= .040 andR2= 0.33,p= .026, respectively), the latter relationship an unexpected pattern for a notorious invader. These data show latitudinal patterns and provide baselines for future comparisons in the wake of projected climate change.
Review: In-Water Systems to Reactively Manage Biofouling in Sea Chests and Internal Pipework
Authors: Growcott Abraham , Kluza Daniel , Georgiades Eugene
Published: April 2017

AbstractSea chests are cavities built into a vessel's hull to aid the efficiency of pumping seawater into internal pipework systems. Sea chests and internal pipework are known hotspots for the accumulation of biofouling, and vessel biofouling is a major pathway for the introduction
and spread of nonindigenous marine species. The use of preventive strategies to minimize biofouling within sea chests and internal pipework is difficult due to their structural complexity; therefore, reactive methods to manage the associated biosecurity risk are required. This review examines
the efficacy, environmental considerations, and cost of different systems to reactively manage sea chest and internal pipework biofouling within operationally realistic time frames (<3 days) and identifies those that warrant further investigation. Physical removal systems with recapture
capability should be developed for accessible areas (e.g., grates), as such systems provide an operational benefit to the vessel. For internal and inaccessible surfaces, the development of thermal systems, particularly steam systems, is encouraged as they offer broad-spectrum efficacy at obtainable
temperatures and require relatively short exposure periods. Compared to chemical treatments, thermal treatments are less influenced by environmental variables (e.g., temperature, water chemistry) and regulatory constraints.

AbstractAlthough there exists a wide range of nonbiocidal and environmentally friendly surface coatings to reduce biofouling on marine structures, there is still not a fundamental understanding of barnacle adhesion upon reattachment. The purpose of this study is to assess
the effect of hydrophobicity on adhesion in the barnacle Amphibalanus amphitrite, an abundant and widespread biofouler. Self-assembled monolayers were made on glass slides from alkyl silanes with methylated and fluorinated terminal groups to produce hydrophobic surfaces. Coated and
uncoated glass slides underwent a 2-week barnacle reattachment assay. Barnacles were removed using a force gauge, and critical shear stress was calculated for each substrate. Following reattachment assays, a Coomassie Blue G250 protein stain was used to quantify the amount of glue remaining
on substrates by measuring pixel density with ImageJ software on glue scans. Critical shear stress was found to be significantly higher for both hydrophobic surfaces as compared to the hydrophilic uncoated glass, and correspondingly, the density of residual glue was higher on hydrophobic surfaces.
Given that hydrophobic substrates can exclude water from the surface, they may provide a protected environment for glue release that is favorable for adhesive bond formation with the substrate as well as inter- and intramolecular bonding within the glue layer. Critical shear stress showed
a strong positive correlation with residual glue density, suggesting that barnacle release occurs primarily via cohesive failure. Scanning Electron Microscope (SEM) micrographs confirm morphological differences in the glue remnants, depending on the substrate coating. Among the hydrophobic
substrates tested, results suggest that contact angle alone is not enough to predict the critical shear stress of barnacles. The chemical and physical properties of the coating become important parameters to consider in antifouling coating design.

The many uses of gluconic acid and some of its salts are arousing increasing interest in these compounds and in their production levels. Although gluconic acid and gluconates can be obtained chemically, they are currently almost exclusively biotechnologically produced, mostly by fungus based methods. There is, however, an ongoing search for alternative microorganisms to avoid the problems of using fungi for this purpose and to improve the productivity of the process. Especially promising in this respect are acetic acid bacteria, particularly Gluconobacter strains. This paper discusses the main variables and operating conditions to be considered in optimizing gluconic acid production by Gluconobacter.

In incidental aneurysms, endovascular treatment can lead to post-procedural headaches. We studied the difference of surgical clipping vs. endovascular coiling in concern to post-procedural headaches in patients with ruptured aneurysms. Sixtyseven patients with aneurysmal subarachnoidal haemorrhage were treated in our department from September 1st 2015 - September 1st 2016. 43 Patients were included in the study and the rest was excluded because of late recovery or highgrade subarachnoid bleedings. Twenty-two were surgical treated and twenty-one were interventionally treated. We compared the post-procedural headaches at the time points of 24 h, 21 days, and 3 months after treatment using the visual analog scale (VAS) for pain. After surgical clipping the headache score decreased for 8.8 points in the VAS, whereas the endovascular treated population showed a decrease of headaches of 3.3 points. This difference was highly statistical significant and remained significant even after 3 weeks where the pain score for the surgically treated patients was 0.68 and for the endovascular treated 1.8. After 3 months the pain was less than 1 for both groups with surgically treated patients scoring 0.1 and endovascular treated patients 0.9 (not significant). Clipping is relieving the headaches of patients with aneurysm rupture faster and more effective than endovascular coiling. This effect stays significant for at least 3 weeks and plays a crucial role in stress relieve during the acute and subacute ICU care of such patients.
Traumatic gastric rupture following blunt abdominal trauma: a case report about an atypical modality of presentation

Gastric rupture following blunt abdominal trauma is a rare presentation with a reported incidence of 0.02-1.7% in current literature. Traumatic gastric rupture is usually associated with other visceral injuries, such as splenic lesions and fractures. Prompt diagnosis and early intervention reduce mortality and morbidity. History of a recent meal has been implicated in traumatic gastric rupture. 2 We report a case of blunt abdominal trauma with an isolated gastric rupture after a motor vehicle accident, managed successfully without any post-operative morbidity and mortality.
Neuromuscular disorder as initial manifestation of secondary hyperparathyroidism – a case report
Authors: Hajjar Karim , Hagenacker Tim
Published: April 2017

This case report describes a young woman who presented with slowly progressing weakness of the proximal limb muscles and slight decrease of muscle tone but otherwise unremarkable neurological history. Diagnostic workup revealed fatty degeneration of the girdle muscles and an excessive increase of the parathyroid hormone as a result of severe vitamin D deficiency. Secondary hyperparathyroidism was diagnosed, and neurological deficits resolved after treatment of the underlying endocrinopathy.
The tongue, mandible, hyoid system
Authors: Messina Giuseppe
Published: April 2017

The craniocervical-mandibular system works in harmony and allows different functional tasks as the postural control of the cervical region. This system is formed by the temporomandibular joint, the masticatory muscles and ligaments connecting the temporomandibular joint and the cervical region. It has been seen to affect human posture, and many disorders of the temporomandibular joints may affect this functional arrangement. Notwithstanding this system considered as a functional arrangement, may offer various clinical explanations, it does not hold anatomical connections with the posterior region of the cranium, thus it should not be refered to as a craniocervical arrangement. For this reason a new interpretation of such system as the tongue, mandible, hyoid system should be considered. Such functional reinterpretation between these three anatomical structures allows further comprehension of specific clinical conditions connected to deglutition aspects or the temporomandibular joint, for such needs to be taken into account during clinical diagnosis and treatment.

The trade in live crustaceans implies keeping these animals alive after capture and/or farming until purchase by the final consumer. Regarding animal welfare, the European Union includes cephalopods in Directive 2010/63/EU on the protection of animals used for scientific purposes, but there are no further regulations on crustaceans in EU legislation. The present study analysed the provisions of Italian municipal regulations on animal welfare applicable to crustaceans. Only 62 of the 110 municipal websites of the provincial capitals reported a regulation safeguarding animal welfare. These regulations contain different rules on: aquaria characteristics (size, volume and shape); management of aquaria; maintenance (preservation and exposure) of live aquatic species; slaughtering and/or suppression of aquatic species and crustaceans; tying of crustacean claws; and crustacean cooking. The analysis on Italian municipal regulations on crustaceans’ animal welfare showed that the provisions are vague, lacking uniformity and scientific guidelines.

Published: April 2017

Considering how to improve efficacy of therapeutic strategies, the overall objective of the present study was to investigate the extent of eating concerns and to identify predictors associated with the severity of disordered eating symptomatology among people with eating pathologies. We screened 80 female eating disordered patients, ranging from 13 to 40 years, by means of self-report measures of parental behavior as perceived by the offspring, self-esteem, perfectionism, body shame and eating disorder severity. Self-reported weight and height were obtained. The diagnosis of bulimia nervosa resulted to be associated with a greater severity of the eating symptomatology. Maladaptive perfectionism, body shame and self-esteem, significantly predicted the level of eating concerns. The recognition of potential maintaining factors may support the choice of particular therapeutic strategies to improve the treatment of eating pathologies and their outcomes.
