AbstractWe examined the influence of prior time‐trials performed at different altitudes on subsequent exercise in moderate hypoxia and associated cardiometabolic and neuromuscular responses. In normobaric hypoxia (simulated altitude 2000 m; FiO2: 0.163), 10 healthy males performed (1) an incremental test to exhaustion (VO2max_2000) and (2) a test to exhaustion at 80% of the power output associated to VO2max_2000 for a reference time (947 ± 336 sec). Thereafter, two sessions were conducted in a randomized order: a cycle time‐trial corresponding to the reference time (TT1) followed 22 min later (passive rest at 2000 m) by a 6‐min cycle time‐trial (TT2). TT1 was either performed at 2000 or 3500 m (FiO2: 0.135), while TT2 was always performed at 2000 m. As expected, during TT1, the mean power output (247 ± 42 vs. 227 ± 37 W; P < 0.001) was higher at 2000 than 3500 m. During TT2, the mean power output (256 ± 42 vs. 252 ± 36 W) did not differ between conditions. Before and after TT1, maximal isometric voluntary contraction torque in knee extensors (pooled conditions: −7.9 ± 8.4%; P < 0.01), voluntary activation (−4.1 ± 3.1%; P < 0.05), and indices of muscle contractility (peak twitch torque: −39.1 ± 11.9%; doublet torques at 100 Hz: −15.4 ± 8.9%; 10/100 Hz ratio: −25.8 ± 7.7%; all P < 0.001) were equally reduced at 2000 m or 3500 m. Irrespective of the altitude of TT1, neuromuscular function remained similarly depressed after TT1 both before and after TT2 at 2000 m. A prior time‐trial performed at different altitude influenced to the same extent performance and associated cardiometabolic and neuromuscular responses during a subsequent exercise in moderate hypoxia.

AbstractGiardiosis is a parasitic disease caused by the protozoanGiardia intestinalis, which is distributed worldwide. Most of the data on the prevalence of giardiosis in Mexico comes from research, but it is also necessary to study the data provided by the Mexican Health Ministry and issued by the General Directorate of Epidemiology. The aim of this work was analyse the national surveillance data for human giardiosis in order to update the epidemiological data of this disease in Mexico. A retrospective observational analysis of giardiosis (from January 2011 to December 2015) was performed in the annual reports emitted by the GDE in Mexico. The cases were classified by year, state, age group, gender and seasons of the year. During the period of 2011–2015, a reduction of 38.51% was observed in the total number of new cases of giardiosis reported in the whole country The states of Sinaloa, Yucatan, and Chiapas presented the highest number of new cases reported during the analysed period. Giardiosis rates were always higher among women in all age groups, but the maximum incidence was observed in both sexes in the age group of 1–4 years old (the most susceptible group). On the other hand, the number of cases increased dramatically in southern states during warmer months. Giardiosis is influenced by ambient temperature changes along the year, although this study suggests that tends to decrease in all the analysed states and could be related to the overall improvement of hygienic practices within the Mexican population,

Published: January 2018

Abstract
The members of Acanthamoeba genus are ubiquitous amoeba which could be a pathogenic parasite. The amoeba is resistant to the common chlorine concentration that used for disinfecting the swimming pool water. Therefore, the pools can be suitable environments for the survival and multiplication of the amoeba. In this cross sectional study, 10 indoor recreational water centers from different regions of Tabriz city were selected and sampling was done from fixed and floating biofilms of the swimming pools and hot tubs. The samples were cultured and monitored for the presence of amoeba cyst or trophozoite. For molecular identification of Acanthamoeba, PCR (polymerase chain reaction) and sequencing were conducted based on genus specific fragment of 18S ribosomal DNA (Rns). Acanthamoeba contamination was observed in 6 centers of 10 recreational centers. Based on the amoeba isolation from fixed and floating biofilms, 2 (20%) swimming pools, and 5 (50%) hot tubs were contaminated. Based on the type of the sample, the highest contamination was found in the hot tub water (40%) and the least was found in the swimming pools water (10%) and fixed biofilms of the swimming pools (10%). Out of 8 isolates, 5 (62.5%) were shown expected product in PCR amplification. Sequence analysis showed that Acanthamoeba isolates belonged to the T3 and T4 genotypes. The study revealed a high degree of contamination in the indoor recreational water centers in Tabriz city. So, it is essential to pay closer attention to the hygiene of swimming pools and hot tubs.
A Note on Cohabitation and Marriage
Authors: Jelnov Artyom , Jelnov Pavel 
Published: January 2018

Abstract
Why do some couples marry, while others prefer cohabitation? The proposed model does not assume utility differences between these two states but assumes separation frictions in marriage and not in cohabitation. We show that high expectations from the relationship lead to marriage even though the utility is drawn from the same distribution as in cohabitation. Moreover, mutual agreement on marriage may take place when the expected utility in partnership is both a private and a common knowledge, although for different sets of expected utility values. Surprisingly, when the expected utility is relatively low, marriage may take place only in the common knowledge environment.
The encoding of motion events in football and cycling live text commentary: A corpus linguistic analysis
Authors: Meier Simon , Thiering Martin 
Published: January 2018

AbstractBased on large annotated corpora of German live commentary reports on football games and cycling races, this paper analyses the varying linguistic means of encoding motion from the perspective of cognitive semantics. We start from the observation that in football adpositional constructions in the accusative case with directional meaning prevail, e.g. in den Strafraum (‘into the box’). As opposed to football, in cycling text commentaries motion tends to be encoded by adpositional constructions in the dative case with locative meaning, e.g. an der Spitze des Hauptfeldes (‘at the top of the peloton’). We argue that in cycle racing motion is usually profiled as position. These findings can be explained with regard to the different perspectives taken by the camera that allow the spectators to take vectorial, hodological or birds-eye-perspectives on the actual event. Hence, the conveyed images induce different viewing arrangements as is known from cognitive semantics’ stage analogy. These arrangements are reflected linguistically in specific construals presenting the ways of conceiving the various frames of moving actors in football games and cycling races.
Synthesis of new 3H-chromeno[2,3-d]pyrimidine-4,6(5H,7H)-diones via the tandem intramolecular Pinner/Dimroth rearrangement

Published: January 2018

Abstract
The reaction of 2-amino-4-aryl-7,7-dimethyl-5-oxo-5,6,7,8-tetrahydro-4H-chromene-3-carbonitriles with excess aliphatic carboxylic acids in the presence of phosphoryl chloride (POCl3) afforded new 2-alkyl-5-aryl-8,8-dimethyl-8,9-dihydro-3H-chromeno[2,3-d]pyrimidine-4,6(5H,7H)-diones in high yields. The suggested mechanism involves a tandem intramolecular Pinner/Dimroth rearrangement. The synthesized compounds were characterized by infrared (IR), proton nuclear magnetic resonance (1H NMR), carbon-13 nuclear magnetic resonance (13C NMR) and elemental analysis.

Published: January 2018

AbstractThis paper describes the use of conventional and unconventional partial discharge tests by capacitive and inductive coupling in Instrument Transformers (IT). The objective of this work was to evaluate Phase-Resolveld Partial Discharge (PRPD) signatures features obtained during on-site (online) and laboratory (offline) measurements, by comparing results with state-of-the-art patterns and standard recommendations. The analysis of the results showed that is possible to obtain partial discharge (PD) patterns - corona, background noise, internal PD, free potential and surface PD - at on-site measurements but those are compromised by the pulse attenuation, difficulties in performing measuring system calibration and the absence of reference voltage. Suitable range of on-site measuring was above 1 MHz up to 5 MHz. The results reached in on-site measuring can be used as image preprocessing methodology to perform automatic pattern recognition of partial discharge signature. It is also described the parameterization of the HFCT for different frequency filter values though carrying out HFCT parameterization for different types of high voltage equipment was not objective of this work.

On Love, Women, and Friendship: Reading Nietzsche with Irigaray
Authors: Verkerk Willow 
Published: January 2018

AbstractThis essay examines Nietzsche’s accounts of love and the gender troubles of friendship. In many passages, Nietzsche situates love as an impairment to friendship. In particular, he believes that erotic or sexual love, understood as a drive that seeks to possess and control the other, prevents two people from entering into the shared project of friendship. Nietzsche implies that gender roles, and the cultural expectations associated with these types, make friendship very difficult between women and men. The reason why women in Nietzsche’s account cannot move from love relationships into friendship is because they are primarily esteemed for their fulfillment of gender stereotypes. In order to avoid the perils of assimilation, pointed to by Nietzsche, it is imperative to develop an ethics of friendship that changes the way people approach and love one another. Luce Irigaray present such an alternative with her account of wonder. She argues that recognition requires a negative movement in which one acknowledges one’s limits in understanding the other. Irigaray designates a transformative and activist potential to love, as a benefit to friendship in its erotic and practical qualities. She claims that when love is expressed alongside the passion of wonder there is a stronger potential for recognition between two people. With the assistance of Irigaray, this essay questions Nietzsche’s assessment that love is an impasse to friendship by asking if love need be as assimilating as Nietzsche proposes.
Treatment and reclamation of hydrocarbon-bearing oily wastewater as a hazardous pollutant by different processes and technologies: a state-of-the-art review
Authors: Kundu Partha , Mishra Indra M. 
Published: January 2018

AbstractHydrocarbon-containing oily wastewater generated by various industries creates a major environmental problem all over the world since petroleum products are commonly used as energy sources and raw materials in various industries. In case of offshore/coastal oil recovery operations, produced water is discharged through either shore side outfalls or coastal rim releases. In many cases, current disposal practices leads to severe environmental pollution by contamination of petroleum hydrocarbon to the surface, ground, and coastal waterways. Therefore, it is necessary to evaluate the performance of various processes for the recovery of petroleum hydrocarbons from wastewater. In this paper, a detailed review on the different separation/treatment processes of oily wastewater is presented. Previous and recent research works are reviewed in the area of oil-water separation from wastewater and also highlight the new developments in these areas. Various separation processes and technologies such as gravity separation, flotation process, membrane process, adsorption process, biological treatment, freeze/thaw process, and photocatalytic oxidation process (PoPs)/advanced oxidation processes (AoPs) are discussed and reviewed. The adsorption properties of a wide variety of porous sorbent materials in oily wastewater treatment, particularly in the area of oil spill cleanup, are also reviewed. The advantages and disadvantages of each process are critically discussed and compared.
Bloggen, Twittern, Posten und Co.
Authors: Klemm Michael 
Published: January 2018

AbstractSocial Media have changed the way we communicate privately or professionally. So the users have to understand the structures and specific conditions, the ›logics‹ and ›ideologies‹ of these new communication frameworks, they have to learn new rhetorical skills. On the other hand the users themselves develop and transform these media permanently in a creative way, as a part of their own media culture. This paper discusses various forms and requirements of ›Social Media Rhetorics‹ between persistence and dynamics, between accomodation and innovation - especially concerning Weblogs, Twitter, Facebook, YouTube and other phenomena as e.g. so called ›memes‹.
Powerpoint und das Pathos digitaler Formular- Rhetorik
Authors: Hagen Wolfgang 
Published: January 2018

AbstractThe essay will discuss how PowerPoint historically emerged (at the turn of the 1980ies) from the mission statement towards the (back then brand new) Graphical User Interface that would provide a new machine/man metaphor called »Private Computer«. Therein was expressed, as the lecture argues, the self-presentation of a locally bound and fast growing corporate economic culture called »Silicon Valley« represented in its own diagrammatical schemes. The immanent rhetoric of the software - developed under the (much more appropriate) name »Presenter« - unwillingly disrupts the digital brilliance of the computer interface in reinforcing it at the same time - a Silicon Valley style of making progress. However, the disclosure of PowerPoint rhetorics as classical formulaic rhetoric shows the boundaries in which the program can be of only limited use. This mixture between a classical old rhetorical style and the build-in-hope of a fantastical new future might explain why a quarter of a century and ten software versions later Powerpoint has become so overwhelmingly popular (used on more than one billion computers), while at the same time mutated into one of the most scandalous bugbears of the digital.
Mercury Cyanamide / Carbodiimide Networks: Synthesis and Crystal Structures of Hg2(NCN)Cl2 and Hg3(NCN)2Cl2

Published: January 2018

Abstract
We report about the synthesis and crystal structure determination of Hg2(NCN)Cl2 (P21/c (No. 14), Z = 4, a = 806.7(1), b = 907.1(2), c = 788.0(1) pm, β = 106.446(3)°, 1374 independent reflections, 67 variables, R1 = 0.0463) and Hg3(NCN)2Cl2 (Pca21 (No. 29), Z = 4, a = 702.0(2), b = 1078.5(2), c = 1050.3(2) pm, 1977 independent reflections, 71 variables, R1 = 0.0380). Both compounds contain infinite -Hg-NCN-Hg- zigzag chains which are linked by additional Hg atoms to result in two-dimensional frameworks characterized by 20-membered rings sharing edges. The remarkably flexible structural backbone [Hg3(NCN)2]2+ hosts additional Cl! anions and HgCl2 molecules in Hg2(NCN)Cl2 but only Cl- anions in Hg3(NCN)2Cl2, by that reaching a high packing efficiency in both cases.While Hg2(NCN)Cl2 exclusively contains carbodiimide N=C=N2- species, Hg3(NCN)2Cl2 is the first structural example of an inorganic network built up from both carbodiimide N=C=N2- and cyanamide N-C≡N2- groups.
Monitoring Shear Strain in Shallow Subsurface Using Mini Pipe Strain Meter for Detecting Potential Threat of Slope Failure
Authors: Tamate Satoshi , Hori Tomohito 
Published: January 2018

Abstract
The following study examines a new soil measurement method to achieve simple and reliable slope monitoring to ensure labor safety. The method measures the increase in shear strain in the shallow subsurface of the slope. The target that is measured in the soil using this method is different from that of the conventional methods, which use extensometers and inclinometers. Although the increase in shear strain in the shallow subsurface is considered negligible, this study discusses the potential application of the measurement for detecting the potential threat of slope failure. A mini pipe strain (MPS) meter was developed to measure shear strain in the shallow subsurface of slopes. A full-scale test model of slope failure was constructed via excavation to examine the detectability of the threat of slope failure using an MPS meter. Corresponding to the development of slip surfaces in deep positions, less than 0.5 % of shear strain in the shallow subsurface is clearly observable. Although the inverse of the shear strain rate (1/ν) showed a drastic decrease prior to failure, the slope did not fail immediately; in addition, creep phenomena was observed. An unstable slope may be considered a stable one because of the lag time prior to failure. Identifying the second or third creep could provide a few minutes for workers to escape. Accordingly, the threat of workers being injured by collapsing soil can be reduced by using the proposed method and sensor.

Characteristics of Yoga Practice and Predictors of Practice Frequency
Authors: Ayala Sujata Ghosh , Wallson Kenneth , Birdee Gurjeet 
Published: January 2018

Abstract
Yoga is a globally popular mind-body practice used for health. The objective of this study was to characterize yoga practice and factors associated with frequency of practice. Yoga practitioners were sent invitations via email to participate in an online survey. Yoga characteristics and other sociodemographics were collected. Data from 309 consenting respondents were analyzed for patterns in practice characteristics (yoga techniques, location of practice, method of instruction, teacher status, and yoga type). Associations between characteristics of practice and yoga practice frequency were computed. The following characteristics were then analyzed as predictors of practice frequency in a regression model: location of practice, method of instruction, teacher status, yoga type, and techniques. Most respondents reported use of all three yoga techniques (movements, breathing, and meditation) and practiced an average of 4.5 ± 1.9 days a week. Key characteristics such as location of practice, method of instruction, and frequency significantly differed by teacher status and by yoga type (Viniyoga practitioners vs. other yoga styles). In our regression model, being a yoga teacher, being taught a one-on-one yoga practice by someone else, and regular use of movement were positively associated with increased practice frequency. Our analyses provide insight into how yoga factors such as teacher status, method of instruction, and use of tools relate to practice frequency. Understanding the relationships between practice characteristics and practice frequency may allow for the improved implementation of yoga for health.
RESISTENCIA AL CORTE DE MUROS DE HORMIGON ARMADO
Authors: Leyva L. Gilberto , Montaño Juan Carlos 
Published: January 2018

Se analiza una serie de datos experimentales disponibles en la literatura sobre resistencia al corte de muros de hormigón armado, estudiándose el efecto de los principales parámetros que afectan esta resistencia. Utilizando el modelo que considera por separado las contribuciones Vs del refuerzo transversal y Vc del hormigón, se detectaron dos importantes efectos. En primer lugar, se determinó que el aporte Vs del refuerzo transversal alcanza solamente al 70% del valor establecido en la norma de diseño del ACI. En segundo lugar, se detectó claramente el efecto de degradación de la contribución del hormigón Vc, causada por la demanda de deformaciones no lineales y el consecuente daño asociado. A partir del estudio analítico del mecanismo de transferencia de corte a través de la cabeza de compresión del muro, y del análisis de los resultados experimentales, se ha desarrollado un modelo de resistencia al corte que incluye los efectos antes mencionados. Dados los datos experimentales disponibles, la demanda de deformaciones no lineales en flexión fue evaluada mediante la ductilidad de curvatura alcanzada al instante de la falla. La expresión obtenida mantiene la forma tradicional, incorporando el efecto de la demanda de ductilidad y del nivel de solicitación en flexión sobre la componente Vc.
