Effects of body movement on the reliability of a portable gas analysis system
Authors: Keefer Daniel J. 
Published: April 2013

PurposeThe purpose of this investigation was to determine the effect of body movement on the ability of a portable telemetric gas analysis device, the Cosmed K4b<sup>2</sup>, to produce a reliable measure of walking oxygen consumption (VO<SUB>2</SUB>).MethodsThirteen adults were asked to report to a laboratory for three test sessions. During Session 1, participants were familiarized with the data collection procedures and completed a 15-min treadmill accommodation. In Sessions 2 and 3, each participant completed four 5-min treadmill walking trials at 1.8 m • sec<sup>–1</sup> under different experimental conditions while VO<SUB>2</SUB> was collected using the portable system. The four conditions were used to manipulate the portable metabolic system to mimic different types of movement.ResultsData analysis revealed no significant differences (<i>p</i> = 0.070) amongst VO<SUB>2</SUB> values across all four experimental conditions during Sessions 2 and 3. Between-day coefficients of variation for the mean VO<SUB>2</SUB> values of the four conditions ranged from 2.7% to 3.8%, with the highest level of variation occurring whilst the unit was strapped to the participant’s chest.ConclusionsViewed collectively, the Cosmed K4b<sup>2</sup> may produce reliable measures of VO<SUB>2</SUB> in adult participants during treadmill walking who exhibit little vertical oscillation. However, future research is necessary to determine if the K4b<sup>2</sup> is a valid instrument for collecting VO<SUB>2</SUB> data if excessive body movement in the vertical direction can affect the data collection instrumentation.
The Occurrence of Soft Rot (Janthinobacterium Agaricidamnosum) In Mushroom (Agaricus Bisporus) Crops
Authors: Pudełko Krzysztof 
Published: April 2013

Abstract
This study evaluated the development of soft rot disease (Janthinobacterium agaricidamnosum) in Agaricus bisporus crops. Symptoms of the disease appeared at the end of the first break of the mushroom’s harvest and mostly occurred in the later stages of cultivation (in the second break and between the 1st and 2nd crop). Distribution of lesions in growing rooms indicated that employees served as a vector of disease infection, which was spread when harvesting the mushrooms. An evaluation of the post-harvest mushrooms showed that fruiting bodies, especially those stored in closed containers, showed disease symptoms when infected at harvest.
Reprogramming immune responses via microRNA modulation

Published: April 2013

AbstractIt is becoming increasingly clear that there are unique sets of miRNAs that have distinct governing roles in several aspects of both innate and adaptive immune responses. In addition, new tools allow selective modulation of the expression of individual miRNAs, both in vitro and in vivo. Here, we summarize recent advances in our understanding of how miRNAs drive the activity of immune cells, and how their modulation in vivo opens new avenues for diagnostic and therapeutic interventions in multiple diseases, from immunodeficiency to cancer. Recent contributions from our laboratory and other groups to novel formulations for miRNA mimetics are further discussed
Invertebrate systems for hypothesis-driven microbiome research

Published: April 2013

AbstractA number of novel, invertebrate systems have emerged as excellent models for the study of microbiomes. Due to their small size, evolutionary diversity, ease of culture, and – in many cases – relatively simple gut communities, invertebrates of many different orders can be tools to drive hypothesis-driven microbiome research. In this review we highlight several host systems amenable to microbiota analyses and specific questions that can be easily addressed in those systems. These questions address functional equivalence across similar habitats, host-specificity and coevolution of host-microbe interactions, and acquisition and transmission dynamics of host-associated communities. We propose that host systems be chosen based on the question of interest, and that insect systems are excellent tools for the vast behavioral, ecological, and genetic diversity that allows them to address a variety of these questions.

Abstract
rithms
for solving the 3D electro-diffusion equations such as
the Poisson-Nernst-Planck equations and the size-modified
Poisson-Nernst-Planck equations in simulations of biomolecular
systems in ionic liquid. A set of transformation methods
based on the generalized Slotboom variables is used to solve
the coupled equations. Calculations of the diffusion-reaction
rate coefficients, electrostatic potential and ion concentrations
for various systems verify the method’s validity and stability.
The iterations between the Poisson equation and the Nernst-
Planck equations in the primitive method and in the transformation
method are compared to illustrate how the new method
accelerates the convergence of the solution. To speed up the
convergence, we introduce the DIIS (direct inversion of the
iterative subspace) method including Simple Mixing and Anderson
Mixing as under-relaxation techniques, the effectiveness
of which on acceleration is shown by numerical tests.
It is worth noting that the primitive method fails to solve the
size-modified Poisson-Nernst-Planck equations for real protein
systems but the transformation method succeeds in the
simulations of the ACh-AChE reaction system and the DNA
fragment. To improve the accuracy of the solution, we introduce
high order elements and mesh adaptation based on an
a posteriori error estimator. Numerical results indicate that
our mesh adaptation process leads to quasi-optimal convergence.
We implement our algorithms using the parallel adaptive
finite element package PHG [53] and high parallel efficiency
is obtained.
Tourism Activities of Deaf Poles
Authors: Zajadacz Alina , Śniadek Joanna 
Published: April 2013

Abstract The chief aim of the research was to identify tourism activities of Deaf Poles. The study was conducted in 2007, and it included 191 Deaf adult Poles. The research data was collected mainly on the basis of questionnaire surveys conducted with the assistance of a sign language interpreter, individual interviews, and participant observation during tourist trips. The results were used as a basis for developing a conceptual framework for creating databanks for analyzing the data. The following statistical methods were employed: statistical significance level (p) and Tourist Information Systems (TIS), adapted to the needs of sign language users. The conceptual framework is based on the idea of active participation of Deaf individuals in creating Tourist Information Systems, cooperation networks (clusters), and the potential of Information Communications Technologies (ICTs).

Published: April 2013

Background. Synovial sarcoma is common in the extremities. Our search revealed only 17 cases of synovial sarcoma of the larynx in the English-language literature.
Case report. We report an additional case of a 37-year-old man with primary laryngeal synovial sarcoma who underwent positron emission tomography/computed tomography (PET/CT) following the treatment. Although the patient received comprehensive therapy including surgery, radiotherapy, repeated chemotherapies, and targeted therapies, he had an unfavourable outcome and died of distant metastases.
Conclusions. In synovial sarcoma of the larynx, PET/CT can detect recurrence and metastasis. PET/CT can also predict the treatment effect in patients with synovial sarcoma.

PurposeStudents’ interest in various forms of physical activity (individual and team sports) is known to differ depending on sex, place of residence, age, the time of year, and many other factors. The aim of the present study was to further analyze this issue on a group of secondary school students and to search for relationships between interest in different sports and sex, age and the school they attend.MethodsA standardized diagnostic questionnaire was administered to 475 first-, second-, and thirdyear students attending two randomly chosen secondary schools in Wrocław, Poland. Results. Significant differences in the interests of the analyzed group were found in regards to sex, age, and school. Girls were more interested in dancing, swimming, downhill skiing and hiking. Boys preferred team sports, swimming, downhill skiing, and martial arts.ResultsSignificant differences in the interests of the analyzed group were found in regards to sex, age, and school. Girls were more interested in dancing, swimming, downhill skiing and hiking. Boys preferred team sports, swimming, downhill skiing, and martial arts.ConclusionsIt seems advisable to identify and implement which physical activities secondary school students find most interesting in existing physical education curriculum so as to help develop positive attitude towards physical culture in later life.

PurposeIn this study, we investigated the effects of the distribution of practice (distributed vs. massed) on the learning of a coincident timing task by young and older adults.MethodsSixteen young adults and sixteen older adults were subdivided into distributed and massed practice groups. The participants completed a coincident timing task that consisted in touching five sensors in sequence under a time constraint in two learning phases: acquisition and transfer.ResultsThere were no performance differences between the groups in the acquisition phase. However, older adults in the massed practice group featured the poorest performance in the transfer test. No differences were found among the other groups.ConclusionsOlder adults are more receptive to distribution practice as massed practice was found to lead to poorer learning. Comparisons of learning effectiveness between young and older adults are dependent on the adopted intra-session intervals. In addition, the conflicting results on distribution of practice may be related to subject–task interactions.

Abstract
Inland excess water floodings are a common problem in the Carpathian Basin. Nearly every year large areas are covered by water due to lack of natural runoff of superfluous water. To study the development of this phenomenon it is necessary to determine where these inundations are occurring. This research evaluates different methods to classify inland excess water occurrences on a study area covering south-east Hungary and northern Serbia. The region is susceptible to this type of flooding due to its geographical circumstances. Three separate methods are used to determine their applicability to the problem. The methods use the same input data set but differ in approach and complexity. The input data set consists of a mosaic of RapidEye medium resolution satellite images. The results of the classifications show that all three methods can be applied to the problem and provide high quality satellite based inland excess water maps over a large area.
Evaluation of Groundwater Quality Using Water Quality Indices in Parts of Lagos-Nigeria
Authors: Akoteyon Isaiah S. 
Published: April 2013

Abstract
Water samples collected from forty-five hand dug wells and thirteen boreholes using random sampling technique were measured for pH, electrical conductivity and total dissolved solids. Calcium, chloride, bicarbonate and carbonates were analyzed using titrimetry method. Magnesium, potassium and sodium by Atomic Absorption Spectrophotometer (AAS) and sulfate was analyzed using a spectrophotometer. The study aims to evaluate groundwater quality using water quality indices in parts of Lagos-Nigeria. The sample locations and spatial variations in the concentration of bicarbonates, Revelle and Water quality indices were mapped using surfer 6.0 software. The result shows that pH indicate extremely acidic to strongly alkaline condition, EC shows medium and high enrichment of salts from location 28 and 21 respectively. Spatially, about 31% and 29.3% of bicarbonate are under poor and moderate zones respectively. The computed Revelle index shows that 41.4% and 1.7% are slightly and strongly influenced by groundwater salinization respectively. Unlike the water quality index, about 12.1% and 1.7% indicate poor and water unfit for drinking respectively. The paper concludes that groundwater salinization is on the increase since over half of the samples are influenced by salinity. Unlike the water quality, it was concluded that the water is of good quality since about 86.2% is suitable for drinking purposes. Based on these findings, it was recommended that waste water treatment and disposal methods should be avoided and appropriate treatment methods to make it more potable and fit for human consumption should be employed in critical locations of the study area.
Estimation of Tourism Climate in the Lake Balaton Region, Hungary
Authors: Németh Ákos 
Published: April 2013

Abstract
Lake Balaton is one of the most important and best-known tourist destinations in Hungary. Although in the last few years, several efforts were implemented to increase the length of the tourist season, the highest visitor turnover occurs in the summer months. We mostly regard the Lake Balaton as a bathing place, despite of the fact that the region offers more and more tourism products. The beach tourism and other lakeside activities are highly dependent on weather and climate. In order to know that a region's climate what extent is suitable to the given tourism activities, the tourism climate potential must be determined. This study aims to illustrate observed changes of the tourism climate potential of Lake Balaton Region during the last half century, by using Tourism Climatic Index (TCI) and Climate-Tourism-Information-Scheme (CTIS). The analysis is based on the long-term measured datasets of Siófok synoptic station. Based on the TCI, the tourism climate potential of the examined region is barely changed over the past 50 years; significant changes can be detected only in February and June. By using the CTIS, smaller changes can also be detected. Such changes are: moderate improvement of the thermal comfort in spring and autumn, slight increase in sunny hours in the tourism season, as well as the sultriness becomes more frequent in the summer months. The results may represent useful background information to the policy decision-makers.
First Records of Scolebythidae And Chrysididae (Hymenoptera, Chrysidoidea) In Rovno Amber
Authors: Perkovsky E. E. , Rasnitsyn A. P. 
Published: April 2013

,
Recorded from the Late Eocene Rovno amber (Ukraine) are above 300 families of Arthropoda. One hundred, seventy-four new species, 35 new genera and one new tribe have been described there in 45 families, including 42 species, 9 genera and one tribe of Hymenoptera. The first record of Scolebythidae is documented herein along with more detail information about Chrysididae which was only mentioned there before. Chrysidids are diverse and not very rare in the Rovno amber: four known inclusions represent at least three species in two genera. This makes a contrast with the Baltic amber: of 34 specimens known to Brues (1933), 30 represent only two species. Genera Pristapenesia BruesPalaeobethylus Brues and Palaeobethyloides Brues and species Palaeobethylus politus Brues and Pristapenesia primaeva Brues, previously known in Baltic amber only, are recorded in Rovno amber as well.

Published: April 2013

Study Design Randomized clinical trial. Objective To compare the effectiveness of manual therapy and exercise (MTEX) to a home exercise program (HEP) in the management of individuals with an inversion ankle sprain. Background An in-clinic exercise program has been found to yield similar outcomes as an HEP for individuals with an inversion ankle sprain. However, no studies have compared an MTEX approach to an HEP. Methods Patients with an inversion ankle sprain completed the Foot and Ankle Ability Measure (FAAM) activities of daily living subscale, the FAAM sports subscale, the Lower Extremity Functional Scale, and the numeric pain rating scale. Patients were randomly assigned to either an MTEX or an HEP treatment group. Outcomes were collected at baseline, 4 weeks, and 6 months. The primary aim (effects of treatment on pain and disability) was examined with a mixed-model analysis of variance. The hypothesis of interest was the 2-way interaction (group by time). Results Seventy-four patients (mean ± SD age, 35.1 ± 11.0 years; 48.6% female) were randomized into the MTEX group (n = 37) or the HEP group (n = 37). The overall group-by-time interaction for the mixed-model analysis of variance was statistically significant for the FAAM activities of daily living subscale (P<.001), FAAM sports subscale (P<.001), Lower Extremity Functional Scale (P<.001), and pain (P⩽.001). Improvements in all functional outcome measures and pain were significantly greater at both the 4-week and 6-month follow-up periods in favor of the MTEX group. Conclusion The results suggest that an MTEX approach is superior to an HEP in the treatment of inversion ankle sprains. Registered at clinicaltrials.gov (NCT00797368).

Authors: Defossez G. , Ingrand P. , Jouhet V. ,   CRISAP,   CoRIM
Published: April 2013

Summary
Objective: The aim of this study was to develop and evaluate a selection algorithm of relevant records for the notification of incident cases of cancer on the basis of the in dividual data available in a multi-source information system.
Methods: This work was conducted on data for the year 2008 in the general cancer registry of Poitou-Charentes region (France). The selection algorithm hierarchizes information according to its level of relevance for tumoral topography and tumoral morphology independently. The selected data are combined to form composite records. These records are then grouped in respect with the notification rules of the International Agency for Research on Cancer for multiple primary cancers. The evaluation, based on recall, precision and F-measure confronted cases validated manually by the registry’s physi -cians with tumours notified with and without records selection.
Results: The analysis involved 12,346 tumours validated among 11,971 individuals. The data used were hospital discharge data (104,474 records), pathology data (21,851 records), healthcare insurance data (7508 records) and cancer care centre’s data (686 records). The selection algorithm permitted performances improvement for notification of tumour topography (F-measure 0.926 with vs. 0.857 without selection) and tumour morphology (F-measure 0.805 with vs. 0.750 without selection).
Conclusion: These results show that selection of information according to its origin is efficient in reducing noise generated by imprecise coding. Further research is needed for solving the semantic problems relating to the integration of heterogeneous data and the use of non-structured information.
Which Mechanics Drive the ‘Franco-German Engine'?
Authors: Leuffen Dirk , Degner Hanno , Radtke Kerstin 
Published: April 2013

Dans cet article, les auteurs théorisent et testent empiriquement les mécanismes qui sont souvent supposés se cacher derrière le « moteur franco-allemand ». Ils ont ainsi tenté de répondre à la question de ce qu’est en fait le « moteur franco-allemand », et comment il fonctionne en théorie et en pratique. L’analyse commence par examiner le « moteur franco-allemand » en termes théoriques. Le modèle défini est ensuite appliqué à une sélection de cas empiriques relatifs à différentes catégories de prise de décision ainsi qu’à des cadres d’action politique. Les résultats montrent qu’il y a peu de preuves d’un « moteur franco-allemand » important dans l’élaboration quotidienne des politiques à Bruxelles, mais qu’il y a effectivement un effet déterminant d’un « moteur franco-allemand » sur « les décisions d’importance historique » dans les domaines du Marché commun, de Schengen, de l’Union économique et monétaire, et de la PESC. Le champ des conditions – en particulier l’éventail des préférences entre tous les États membres de l’UE – détermine fortement le fonctionnement, mais aussi les chances de succès des initiatives communes d’intégration franco-allemandes.

El patrimonio histórico de las obras públicas y su conservación: los puentes
Authors: Fernández Troyano Leonardo 
Published: April 2013

Existe en España un importante patrimonio histórico de obras públicas al que debe darse la debida atención en este aspecto.
Hasta finales del siglo XVIII la única técnica utilizada para hacer puentes durables era la de arcos de piedra. En nuestro siglo las exigencias del tráfico y las técnicas de construcción de puentes han variado radicalmente. Ello supone una variación de actitud respecto de los puentes históricos y obliga a optar por una de estas dos posibilidades:
a)	Adaptarlos a las necesidades actuales del tráfico, lo que supone una transformación sustancial del puente con fuerte deterioro de sus cualidades formales.
b)	Sustituirlos por un nuevo puente. El puente antiguo se queda sin función y, por tanto, pierde su carácter de obra de ingeniería. En general se abandona totalmente, deteriorándose hasta su hundimiento.
El estudio de estas opciones y de los problemas que se plantean en estos puentes es la intención fundamental del presente artículo.
