Formation of Neutral Disk-Like Zone Around the Active Hot Stars in Symbiotic Binaries
Authors: Cariková Z. , Skopal A. 
Published: March 2017

Abstract
In this contribution we present the ionization structure in the enhanced wind from the hot star in symbiotic binaries during active phases. Rotation of the hot star leads to the compression of the outflowing material towards its equatorial plane. As a result, a neutral disk-like zone around the active hot star near the orbital plane is created. We modeled the compression of the wind and calculated the neutral disk-like zone in the enhanced wind from the hot star using the equation of the photoionization equilibrium. the presence of such neutral disk-like zones was also suggested on the basis of the modeling the spectral energy distribution of symbiotic binaries. We confront the calculated ionization structures in the enhanced wind from the hot star with the observations. the calculated column density of the neutral hydrogen atoms in the neutral disk-like zone and the emission measure of the ionized part of the wind from the hot star are in a good agreement with the quantities derived from observations during active phases. the presence of such neutral disk-like zones is transient, being connected with the active phases of symbiotic binaries. During quiescent phases, such neutral disk-like zones cannot be created because of insufficient mass-loss rate from the hot star.
Symbiotic Nova PU Vul - 33 Years of Observations
Authors: Shugarov S. , Chochol D. , Kolotilov E. 
Published: March 2017

Abstract
We present UBVRI light curves of the symbiotic nova PU Vul after its outburst in 1978. Three observed eclipses of the hot component by the cool one were used to determine the ephemeris of the binary system as JD (Min I) = 2444550(15) + 4897(10) × E days. the 194-day shift of the secondary minimum from its expected positions in 2001 suggests the eccentricity of the binary orbit. Period analysis of the VRI photometry improved the pulsation period of the cool AGB variable in the system to P = 217.7 days. Pulsation of the cool component is detected only in the phases around the primary minimum, when the visible hemisphere of the AGB star is not influenced by the interaction with the hot component.
Makarios’ cycle of epigrams on the Psalms Bodleian Baroccianus 194
Authors: Meesters Renaat , Praet Raf , Bernard Floris , Demoen Kristoffel 
Published: March 2017

AbstractThis article provides the editio princeps of a cycle of eight dodecasyllabic poems on the Psalms preserved in Bodleian Baroccianus 194 (15th century). Four of these poems are also present in other manuscripts and enjoyed a certain degree of popularity as book epigrams. The four others are found in this manuscript only. The cycle contains an acrostic: ΜΑΚΑΡΙΟΥ. This Makarios is likely to have compiled the cycle and to have composed the otherwise unknown poems. The Psalms themselves are not included in the manuscript. Only two short commentaries on the Psalms precede and follow the cycle. This implies that at least the four known book epigrams lost their original function as poems referring deictically to the Psalms. A verse prayer to the Trinity that was preserved on the same folio is edited in an appendix.
Reliability vs. granularity in discourse annotation: What is the trade-off?
Authors: Crible Ludivine , Degand Liesbeth 
Published: March 2017

AbstractWe report on the results of an annotation experiment comparing naïve and expert coders in a sense disambiguation task consisting in the assignment of function labels to discourse markers (e.g.well, but, I mean) in spoken French and English using a taxonomy specifically designed for speech. Our qualitative-quantitative assessment of its reliability led us to suggest fundamental revisions of the structure of the taxonomy, striving to find a better balance between reliability and granularity. The resulting model articulates two independent levels of annotation (domains and functions) which, once combined, provide a robust tool for the analysis of discourse markers and relate them to more general functions of spoken language.
Tribological behavior of a newly developed AA2014/waste eggshell/SiC hybrid green metal matrix composite at optimum parameters
Authors: Dwivedi Shashi Prakash , Sharma Satpal , Mishra Raghvendra Kumar 
Published: March 2017

AbstractThe effect of waste carbonized eggshell and silicon carbide (SiC) wt.% on the dry sliding wear behavior of AA2014 alloy green composites produced by electromagnetic stir casting method was investigated. The percentage of waste carbonized eggshell particles and SiC particles varied from 2.5% to 12.5%. The tribological behavior of AA2014/waste carbonized eggshell/SiC hybrid green metal matrix composites (MMCs) was investigated on a pin-on-disc apparatus. The weight percentages of waste carbonized eggshell and of SiC, normal load, and sliding speed and distance were taken as input process parameters, and wear rate was taken as a response. Response surface methodology was used to plan and analyze the experiment. Minimum wear rate was found to be 8.89×10−5mm3/m with desirability one at optimum parameters of 1.75 m/s (sliding velocity), 6.5 (carbonized eggshell wt.%), 34.24 N (normal load), 1219.63 m (sliding distance), and 11 wt.% (SiC wt.%). In the confirmation experiment, the experimental wear rate of the hybrid green MMC at optimum parameters was found to be 9.5×10−5. Results showed that the experimental wear rate and density of the hybrid green MMC were reduced by about 36.66% and 0.35%, respectively, compared with the matrix.

Published: March 2017

Abstract
Oligomeric proanthocyanidins (OPC) rich extracts (OPCEs) were isolated by sequential extraction from the bark of the deciduous trees grey alder (Alnus incana), black alder (Alnus glutinosa) and goat willow (Salix caprea). The yields of OPCE from all barks under study were rather similar and varied between 12.3% and 15.4% based on the oven dry (o.d.) bark. Content of proanthocyanidins in OPCEs ranged from 16.6% to 25% based on o.d. extract. The OPCEs were characterised by means of antioxidant activity with ABTS˙+ and DPPH˙ radical scavenging tests. All extracts being introduced into lipid-based substrates, i.e. mayonnaise and a basic composition of a cosmetic cream, showed antioxidant activity comparable to the reference commercial antioxidant tert-butylhydroquinone (TBHQ). The results of in vitro tests have revealed that the OPCEs could be useful for the human organism as they activated malfunctions of amylase, inhibited pancreatic lipase activity (duodenal digestion model), decreased lipid absorption in blood and decreased pyruvate level in blood plasma essential for regulation of carbohydrate metabolism. The data obtained confirms the advantages of OPC and OPCEs applications as an antioxidant additive for food, cosmetic and health industries.

Abstract

Background:
Physical inactivity contributes to many health issues. The WHO-recommended physical activity for adolescents encompasses aerobic, resistance, and bone strengthening exercises aimed at achieving health-related physical fitness. Heart rate variability (HRV) and maximal aerobic capacity (VO2max) are considered as noninvasive measures of cardiovascular health. The objective of this study is to compare the effect of structured and unstructured physical training on maximal aerobic capacity and HRV among adolescents.

Methods:
We designed a single blinded, parallel, randomized active-controlled trial (Registration No. CTRI/2013/08/003897) to compare the physiological effects of 6 months of globally recommended structured physical activity (SPA), with that of unstructured physical activity (USPA) in healthy school-going adolescents. We recruited 439 healthy student volunteers (boys: 250, girls: 189) in the age group of 12–17 years. Randomization across the groups was done using age and gender stratified randomization method, and the participants were divided into two groups: SPA (n=219, boys: 117, girls: 102) and USPA (n=220, boys: 119, girls: 101). Depending on their training status and gender the participants in both SPA and USPA groups were further subdivided into the following four sub-groups: SPA athlete boys (n=22) and girls (n=17), SPA nonathlete boys (n=95) and girls (n=85), USPA athlete boys (n=23) and girls (n=17), and USPA nonathlete boys (n=96) and girls (n=84).

Results:
We recorded HRV, body fat%, and VO2 max using Rockport Walk Fitness test before and after the intervention. Maximum aerobic capacity and heart rate variability increased significantly while heart rate, systolic blood pressure, diastolic blood pressure, and body fat percentage decreased significantly after both SPA and USPA intervention. However, the improvement was more in SPA as compared to USPA.

Conclusions:
SPA is more beneficial for improving cardiorespiratory fitness, HRV, and reducing body fat percentage in terms of magnitude than USPA in adolescent individuals irrespective of their gender and sports activities.
Multimodal rhetoric: Fictive interaction strategies in political discourse
Authors: Oakley Todd 
Published: March 2017

Abstract
This article explores the role fictive interaction plays in two recent political speeches during the 2012 election year in the United States. The first is actor Clint Eastwood’s keynote address to the Republican National Convention in which he engages in a fictional conversation with President Barack Obama; and the second is by Mark Sanford, former Republican governor of South Carolina and candidate for US Congress who stages a fictive debate with Democratic representative and minority party leader, Nancy Pelosi. Eastwood’s performance was roundly criticized in the media by partisans, pundits, reporters, and analysts across the political spectrum, many of whom openly speculated that the 82-year-old was exhibiting signs of senescence. Sanford’s performance did not receive the publicity of the former but was viewed by voters of South Carolina, and represents a much tighter and effective form of fictive interaction, eventually leading to his election to congress. The factors contributing to the failure of Eastwood’s performance and and those contributing to success of Sanford’s will be the focus of this analysis. Special attention will be paid to the multimodal dimensions of each performance.

Abstract
In the next 10 to 20 years humankind will return to the Moon and/or travel to Mars. It is likely that astronauts will eventually build permanent settlements there, as a base for long-term crew tended research tasks. It is obvious that the crew of such settlements will need food to survive. With current mission architectures the provision of food for longduration missions away from Earth requires a significant number of resupply flights. Furthermore, it would be infeasible to provide the crew with continuous access to fresh produce, specifically crops with high water content such as tomatoes and peppers, on account of their limited shelf life. A greenhouse as an integrated part of a planetary surface base would be one solution to solve this challenge for long-duration missions. Astronauts could grow their own fresh fruit and vegetables in-situ to be more independent from supply from Earth. This paper presents the results of the design project for such a greenhouse, which was carried out by DLR and its partners within the framework of the Micro-Ecological Life Support System Alternative (MELiSSA) program. The consortium performed an extensive system analysis followed by a definition of system and subsystem requirements for greenhouse modules. Over 270 requirements were defined in this process. Afterwards the consortium performed an in-depth analysis of illumination strategies, potential growth accommodations and shapes for the external structure. Five different options for the outer shape were investigated, each of them with a set of possible internal configurations. Using the Analytical Hierarchy Process, the different concept options were evaluated and ranked against each other. The design option with the highest ranking was an inflatable outer structure with a rigid inner core, in which the subsystems are mounted. The inflatable shell is wrapped around the core during launch and transit to the lunar surface. The paper provides an overview of the final design, which was further detailed in a concurrent engineering design study. During the study, the subsystem parameters (e.g. mass, power, performance) were calculated and evaluated. The results of the study were further elaborated, leading to a lunar greenhouse concept that fulfils all initial requirements. The greenhouse module has a total cultivation area of more than 650 m² and provides more than 4100 kg of edible dry mass over the duration of the mission. Based on the study, the consortium also identified technology and knowledge gaps (not part of this paper), which have to be addressed in future projects to make the actual development of such a lunar greenhouse, and permanent settlements for long-term human-tended research tasks on other terrestrial bodies, feasible in the first place.
Shadow Economy: Estimation Methods, Problems, Results and Open questions
Authors: Schneider Friedrich , Buehn Andreas 
Published: March 2017

AbstractThis paper presents various methods used for estimating the size of the shadow economy. Each method is evaluated and its strengths and weaknesses are discussed, as well as results each method yields. The purpose of the paper is threefold: Firstly, to demonstrate that there is no single infallible method for estimating the size and development of the shadow economy and results can differ significantly between different approaches. The MIMIC approach, discussed in greater detail, is often used due to its flexibility. Secondly, the paper discusses the very definition of the shadow economy and factors contributing to its growth. Finally, latest estimations of the size of the shadow economies of 143 countries over the period 1996 to 2014 are presented.

Published: March 2017

AbstractMany chemotherapeutic compounding units are confronted with the problem of product delivery to different care wards. We think that transport by a pharmacy agent does not permit appropriate traceability (wrong care service delivery), control of storage temperature and management of urgency. We have developed a delivery system based on the association of a pneumatic transport system (PTS) and monitored buffer storage area. Thus, after pharmaceutical inspection, chemotherapies are placed in specific and hermetic carriers in the PTS but not directly delivered to care units. In the monitored buffer storage, a robotic arm organizes chemotherapies and waits for the nurse call just before administration. This system permits a real traceability for each stage of the chemotherapy circuit and so, we are now able to certify that chemotherapeutics have been maintained at the correct temperature through continual monitoring. It’s an important prerequisite in standardization and reassignment. Finally, an important issue linked to the use of PTS is the risk of damaging the chemotherapeutics. Data obtained from literature and manufacturers for antibodies highlight the low risk to use a PTS.
Überlagerung der Störeinflüsse mehrerer Streuobjekte auf die Zielgröße eines Doppler-Drehfunkfeuers (DVOR)
Authors: Sandmann Sergei , Garbe Heyno 
Published: March 2017

Zusammenfassung
Der störende Einfluss von Streuobjekten auf die Zielgröße
(geometrischer Winkel) von Doppler Very High Frequency Omnidirectional
Radio Range (DVOR) Drehfunkfeuern stellt eine komplexe Struktur im
Raum dar. Im Fall von mehreren Streuobjekten ergibt sich eine
Überlagerung der einzelnen Störbeiträge. Von besonderem Interesse in
diesem Zusammenhang ist die resultierende Struktur des Störeinflusses,
die von der Art der Überlagerung bestimmt wird. Abhängig von der
Korrelation der einzelnen Störbeiträge sind sowohl konstruktive als
auch destruktive Überlagerungen möglich. In dieser Arbeit wird
gezeigt, dass eine pauschale lineare Addition der einzelnen
Störbeiträge den resultierenden Störeinfluss der Streuobjekte deutlich
überschätzt und einen Grenzfall beschreibt, der eine vollständige
Korrelation der einzelnen Störbeiträge voraussetzt. Des Weiteren wird
anhand von Simulationen verschiedener Konstellationen von
Windenergieanlagen erläutert, dass eine geometrische Addition den
kombinierten Störeinfluss weitaus realistischer abschätzt.
Mfn2 is critical for brown adipose tissue thermogenic function

Published: March 2017

AbstractMitochondrial fusion and fission events, collectively known as mitochondrial dynamics, act as quality control mechanisms to ensure mitochondrial function and fine‐tune cellular bioenergetics. Defective mitofusin 2 (Mfn2) expression and enhanced mitochondrial fission in skeletal muscle are hallmarks of insulin‐resistant states. Interestingly, Mfn2 is highly expressed in brown adipose tissue (BAT), yet its role remains unexplored. Using adipose‐specific Mfn2 knockout (Mfn2‐adKO) mice, we demonstrate that Mfn2, but not Mfn1, deficiency in BAT leads to a profound BAT dysfunction, associated with impaired respiratory capacity and a blunted response to adrenergic stimuli. Importantly, Mfn2 directly interacts with perilipin 1, facilitating the interaction between the mitochondria and the lipid droplet in response to adrenergic stimulation. Surprisingly, Mfn2‐adKO mice were protected from high‐fat diet‐induced insulin resistance and hepatic steatosis. Altogether, these results demonstrate that Mfn2 is a mediator of mitochondria to lipid droplet interactions, influencing lipolytic processes and whole‐body energy homeostasis.

Published: March 2017

Objective
Premature thelarche and precocious puberty are frequently diagnosed in girls even below 6 years of age and may be difficult to differentiate in the early stages. A GnRH test is often included in the diagnostic work-up, although interpretation of the GnRH test in girls below 6 years of age is challenging, as no reference interval exists for this age group. The objective is to determine the normal FSH and LH response to a GnRH test in healthy prepubertal girls below 6 years of age.

Design and methods
A standardized GnRH test, baseline reproductive hormones, clinical evaluation and bone age were determined in all participants. Forty-eight healthy normal-weight girls aged 3.5 ± 0.2 years (range: 0.8–5.9 years) were included. Serum concentrations of LH and FSH were measured before and 30 min after the gonadorelin injection.

Results
The 30-min LH responses (mean ± 2 s.d.) were 5.2 ± 4.0 and 2.9 ± 2.5 IU/L and the FSH responses were 23.3 ± 16.2 and 14.5 ± 10.3 IU/L in girls aged 0.8–3.0 years and 3.0–5.9 years respectively. This corresponds to upper cut-off limits for LH of 9.2 IU/L (<3 years) and 5.3 IU/L (3–6 years). The stimulated LH/FSH ratio was 0.23 ± 0.19 (range 0.06–0.43) and did not correlate with age.

Conclusions
We found that LH increases up to 9.2 IU/L during GnRH test in healthy normal-weight girls below 3 years of age and that the stimulated LH/FSH ratio did not exceed 0.43. Our findings have important implications for appropriate diagnosis of central precocious puberty in girls below 6 years of age.

Abstract

Objective
Continuous or frequent overtime work has been shown to have harmful effects on human health. Meanwhile, one of the main reasons for tooth loss is caries. The aim of this study was to assess the relationship between overtime work and untreated decayed teeth in male financial workers.

Methods
The participants were recruited by applying screening procedures to a pool of Japanese registrants in an online database. Participants filled out a questionnaire about their oral health, behavior, and working conditions. Participants comprised a total of 951 financial male workers, aged 25-64 years.

Results
The likelihood of tooth decay increased with amount of overtime work (p=0.002). After adjusting for age, income, educational background, oral hygiene behavior, snacking behavior, regular dental visitation, bad interpersonal relationships at work, and smoking habit, a multiple logistic regression analysis found that participants with 45-80 h of overtime work (odds ratio [OR], 2.56; 95% confidence interval [CI], 1.23-5.33) or over 80 h of overtime work (OR, 3.01; 95% CI, 1.13-7.97) were more likely to have untreated tooth decay. The percentage of participants who gave “ too busy with work” as the reason for leaving decayed teeth untreated increased with amount of overtime (p&lt;0.001).

Conclusion
These results indicate that overtime work is strongly related to untreated decayed teeth. In addition to oral health education and dental checkups, decreasing stress and decreasing the amount of overtime work may also have a positive effect on oral health in the workplace.
