Rapid apsidal motion in eccentric eclipsing binaries: OX Cassiopeia, PV Cassiopeia, and CO Lacertae

Aims. Double-lined eclipsing binaries are a traditional tool to test the capability of the stellar evolutionary models. If such binaries show apsidal motion, it is also possible to check, in addition to their absolute dimensions, some aspects of their internal structure. In order to perform this additional test, we monitored the times of a minimum of three eclipsing binaries with accurate absolute dimensions. Methods. Approximately thirty new precise times of minimum light recorded with CCD photometers were obtained for three earlytype eccentric-orbit eclipsing binaries OX Cas (P = 2. 49, e = 0.041), PV Cas (1. d 75, 0.032), and CO Lac (1. d 54, 0.029). O− Cd iagrams were analyzed by the Lacy’s method using all reliable timings found in the literature, and the elements of apsidal motion were improved. On the other hand, stellar models computed for the precise observed masses of the three systems were used as theoretical tools to compare with the observed shift in the periastron position. Results. We confirm very short periods of apsidal motion of approximately 38.2, 91.0, and 43.4 years for OX Cas, PV Cas, and CO Lac, respectively. The relativistic effects are negligible, being up to 6% of the total apsidal motion rate in all systems. The corresponding observed apsidal motion rates are in good agreement with the theoretical predictions, except for the case of PV Cas, whose components seem to be more mass concentrated than the models predict.
Compositional and Mineralogical Effects on Ice Nucleation Activity of Volcanic Ash

Volcanic ash produced during explosive eruptions may serve as ice nuclei in the atmosphere, contributing to the occurrence of volcanic lightning due to tribocharging from ice–ice or ice–ash collisions. Here, different ash samples were tested using deposition-mode and immersion-mode ice nucleation experiments. Results show that bulk composition and mineral abundance have no measurable effect on depositional freezing at the temperatures tested, as all samples have similar ice saturation ratios. In the immersion mode, there is a strong positive correlation between K2O content and ice nucleation site density at −25 °C and a strong negative correlation between MnO and TiO2 content at temperatures from −35 to −30 °C. The most efficient sample in the immersion mode has the highest surface area, smallest average grain size, highest K2O content, and lowest MnO content. These results indicate that although ash abundance—which creates more available surface area for nucleation—has a significant effect on immersion-mode freezing, composition may also contribute. Consequently, highly explosive eruptions of compositionally evolved magmas create the necessary parameters to promote ice nucleation on grain surfaces, which permits tribocharging due to ice–ice or ice–ash collisions, and contribute to the frequent occurrence of volcanic lightning within the eruptive column and plume during these events.
tRNA 50-end repair activities of tRNA guanylyltransferase (Thg1)-like proteins from Bacteria and Archaea

The tRNA guanylyltransferase (Thg1) family comprises a set of unique 30–50 nucleotide addition enzymes found ubiquitously in Eukaryotes, where they function in the critical G 1 addition reaction required for tRNA maturation. However, in most Bacteria and Archaea, G 1 is genomically encoded; thus post-transcriptional addition of G 1 to tRNA His is not necessarily required. The presence of highly conserved Thg1-like proteins (TLPs) in more than 40 bacteria and archaea therefore suggests unappreciated roles for TLP-catalyzed 30–50 nucleotide addition. Here, we report that TLPs from Bacillus thuringiensis (BtTLP) and Methanosarcina acetivorans (MaTLP) display biochemical properties consistent with a prominent role in tRNA 50-end repair. Unlike yeast Thg1, BtTLP strongly prefers addition of missing N+1 nucleotides to 5 0-truncated tRNAs over analogous additions to full-length tRNA (kcat/KM enhanced 5–160-fold). Moreover, unlike for 1 addition, BtTLP-catalyzed additions to truncated tRNAs are not biased toward addition of G, and occur with tRNAs other than tRNA. Based on these distinct biochemical properties, we propose that rather than functioning solely in tRNA maturation, bacterial and archaeal TLPs are well-suited to participate in tRNA quality control pathways. These data support more widespread roles for 30–50 nucleotide addition reactions in biology than previ-
When verbal predicates go fronting

This paper demonstrates that there are no empirical and theoretical motivations for regarding verbal predicate focus constructions as (diachronically) derived from cleft constructions. Instead, it is argued that predicate fronting for the purpose of focus or topic is comparable to verb (phrase) fronting structures in other languages (e.g., Germanic). The proposed analysis further indicates that related doubling strategies observed in certain languages are the consequences of parallel chains that license the fronted verb (phrase) in the left periphery, and the Agree-tense-aspect features inside the proposition.
Integrated management of wilt of cumin (Cuminum cyminum L.)

Four components of integrated management namely, soil solarization, crop rotation, chemicalsand biocontrol agents were tested under field condition at Junagadh (Gujarat) for themanagement of wilt of cumin (Cuminum cyminum) caused by Fusarium oxysporum f. sp.cumini. Growing of sorghum (Sorghum bicolor) or maize (Zea mays) during kharif seasondid not reduce wilt incidence during the following rabi season. Soil solarization with 25 μmLLDPE plastic cover for 15 days in summer proved most effective in reducing wilt incidenceto 26.27% as against 44.90% in non-solarization and increasing yield to 396 kg ha-1 as against286 kg ha-1 in non-solarized plots. Application of carbendazim granules @ 10 kg ha-1 onemonth after sowing or Trichoderma viride in organic carrier @ 62.5 kg ha-1 at sowing timewere also effective. Integrating soil solarization followed by growing of sorghum in kharifand application of either carbendazim granules @ 10 kg ha-1 one month after sowing orapplication of T. viride in organic carrier @ 62.5 kg ha-1 was effective for the management ofcumin wilt.
THE LOWER APPROXIMATION OF EIGENVALUE BY LUMPED MASS FINITE ELEMENT METHOD ∗1)

In the present paper, we investigate properties of lumped mass finite element method (LFEM hereinafter) eigenvalues of elliptic problems. We propose an equivalent formulation of LFEM and prove that LFEM eigenvalues are smaller than the standard finite element method (SFEM hereinafter) eigenvalues. It is shown, for model eigenvalue problems with uniform meshes, that LFEM eigenvalues are not greater than exact solutions and that they are increasing functions of the number of elements of the triangulation, and numerical examples show that this result equally holds for general problems.
Torus Models of the Outer Disc of the Milky Way using LAMOST Survey Data

With a sample of 48,161 K giant stars selected from the LAMOST DR 2 catalogue, we construct torus models in a large volume extending, for the first time, from the solar vicinity to a Galactocentric distance of $\sim 20$ kpc, reaching the outskirts of the Galactic disc. We show that the kinematics of the K giant stars match conventional models, e.g. as created by Binney in 2012, in the Solar vicinity. However such two-disc models fail if they are extended to the outer regions, even if an additional disc component is utilised. If we loosen constraints in the Sun's vicinity, we find that an effective thick disc model could explain the anti-centre of the MW. The LAMOST data imply that the sizes of the Galactic discs are much larger, and that the outer disc is much thicker, than previously thought, or alternatively that the outer structure is not a conventional disc at all. However, the velocity dispersion $\sigma_{0z}$ of the kinematically thick disc in the best-fitting model is about 80 km s$^{-1}$ and has a scale parameter $R_{\sigma}$ for an exponential distribution function of $\sim 19$ kpc. Such a height $\sigma_{0z}$ is strongly rejected by current measurements in the solar neighbourhood, and thus a model beyond quasi-thermal, two or three thin or thick discs is required.
EVALUATION OF FUNGICIDES AND HERBICIDES AGAINST THE ROOT ROT OF OKRA

Okra (Abelmoschus esculentus L.) is an important vegetable crop, severely attacked by root rot (Fusarium solani) in Junagadh district, Gujarat state (India). Therefore affords were made to screen the different systemic, contact and combination of fungicides and herbicides in vitro condition against test fungus. Among systemic fungicides, tebuconazole 25.9% EC gave cent per cent growth inhibition of test fungus followed by epoxyconazole 5% WP (92.69%) whereas contact fungicides, copper hydroxide 77% WP and thiram 75% WP were found effective and gave 91.94 and 78.04 per cent growth inhibition of test fungus. The combination of fungicides cymoxanil 8% WP + mancozeb 64% WP, metiram 55% WG + pyraclostrobin 5% WG and carbendazim 12% WP + mancozeb 63% WP gave cent per cent growth inhibition of test fungus. While in herbicides, oxadiargyl was proved to be most effective and gave cent per cent growth inhibition of test fungus followed by quizalophop-pethyle with mean per cent inhibition of 94.72 per cent.
The West and Islam Perspective of Leadership

The paper attempts to compare leadership as perceived from the conventional western approach with that of Islam’s. Although it is conceptual and on a viewpoint mode, it is critical in order to pacify some of the western media findings and opinion with regard to the political turmoil in many Islamic countries. Only ten leadership facets are discussed within this paper. Many leaders would adopt the conventional management leadership based on the available literature which was rationally derived through years of research and practices. Undeniably leaders of Muslim countries are guided by the same source. But pious Muslim leaders are also obliged to consider in parallel, guidelines and rules from the revealed sources, namely the Holy Book, Holy Prophet and His Caliphs. Thus leaders with different religion and countries can face the same issues and derive at decisions rationally but yet different.

PRODUCTION OF ENDOGLUCANASE FROM A THERMOPHILIC FUNGUS

Many species of fungi are good source of several important enzymes. In the present studies, an endoglucanase (endo-1,4-D-glucanase, EC 3.2.1.4) was produced from a thermostable fungus Chaetomium thermophile. It was grown on Vogel's medium with different carbon sources like xylan, carboxymethylcellulose, corncobs and glucose for 5-days at 180 rpm at 28°C in orbital shaker. Production of endoglucanase was very low with glucose as carbon source, whereas xylan and carboxymethylcellulose produced the enzymes in appreciable amount. Growth conditions of Chaetomium thermophile were optimized for maximal production of endoglucanase (EG): pH 5.0, temperature 50°C, incubation period 120 h, substrate 1% CMC. The enzyme was produced and isolated from the culture filtrate through centrifugation. The crude enzyme extract had 0.064 IU/mL endoglucanase activity. Total protein in the crude extract was 0.103 mg/mL and the specific activity was 0.615 IU/mg.
Realization of A Self-Powered ZnO MSM UV Photodetector with High Responsivity Using An Asymmetric Pair of Au Electrodes

We demonstrate a novel type of ZnO self-powered photodetector based on the asymmetric metal-semiconductor-metal (MSM) structure: one Au interdigitated electrode with wide fingers and the other one with narrow fingers. These ZnO photodetectors exhibit attractive photovoltaic characteristics at 0 V bias. More interestingly, with increasing the asymmetric ratio (the width of wide fingers : the width of narrow fingers) of the interdigitated electrodes, the responsivity of the ZnO self-powered UV photodetectors was enhanced obviously, reaching as high as 20 mA W−1 when the asymmetric ratio was 20 : 1. A physical model based on band energy theory was developed to illustrate the origin of the photoresponse at 0 V in our device. Our findings provide a new route to realizing self-powered photodetectors.
Bacterial migration through low-permeability fault zones in compartmentalised aquifer systems: a case study in Southern Italy

*emma.petrella@unimol.it Microbial contamination is frequently detected at different springs discharging within this type of aquifer system (Celico et al., 2004; Naclerio et al., 2008, 2009) and in carbonate environments in general (e.g., Personné et al., 1998; Pronk et al., 2006; Flynn & Sinreich, 2010). Nevertheless, no information is available concerning the role low-permeability fault zones play in the migration of microorganisms between adjacent compartments. Whether a fault zone will act as a conduit, barrier, or combined conduit-barrier system is controlled by the relative percentage of fault core and damage zone structures (e.g., in carbonates, Mollema & Antonellini, 1999; Salvini et al., 1999; Billi et al., 2003; Billi, 2005a; Agosta & Aydin, 2006; Billi et al., 2007; Balsamo et al., 2008; Storti & Balsamo, 2010). A fault zone can impede fluid flow when the fault core is well developed (e.g., Antonellini & Aydin, 1994; Newman & Mitra, 1994; Goddard & Evans, 1995; Caine et al., 1996; Bense et al., 2003; Fairley & Hinds, 2004). Fault cores can include single slip surfaces (Caine et al., 1991), highly indurated, INTRODUCTION
Identification of obstacles ahead of tunnel face applying inverse approach

One of the major challenges in tunnelling is the assessment of the location and properties of large stiff or weak zones ahead of the tunnel face. In this paper a concept is presented, how numerical modelling in conjunction with displacement measurements at the tunnel lining over construction stages can be used for identification of geometrical and constitutive parameters of a hard rock inclusion in front of the tunnel face. The size of the inclusion, its position and material parameters are determined by back analysis. The obtained results show that a robust in nonlinear applications optimization algorithm such as the Particle Swarm Optimisation (PSO) is an efficient tool for geometric and material model parameter identification based on measurements during the tunnel construction. The concrete application reported here concerns the determination of the size and position of a stiff rock inclusion ahead of the tunnel advance. The prospective of using PSO in solving specific tasks related to tunnelling is also discussed.
The role of perceived product quality and overall satisfaction on purchase intentions

The study investigated the effects of perceived product quality and overall satisfaction on purchase intentions. Moreover, the direct and indirect effects of values and involvement on purchase intentions were studied. The study utilized the survey questionnaire and used sport shoes as the product being researched. The sample consisted of 197 students who responded to an anonymous questionnaire. Five hypotheses were tested and four of them were confirmed by the data. Perceived quality had a direct and an indirect effect (through overall satisfaction) on purchase intentions, overall satisfaction had a direct effect on purchase intentions and involvement had an indirect effect on purchase intentions through overall satisfaction and perceived quality. The results of the study provide several theoretical and practical implications.
Fibromyalgia Symptoms – A Review

Fibromyalgia (FM) is the second most common rheumatologic disorder, affecting 5% of the world population, and has a serious effect on the quality of life of patients, as well as an economic impact through lost workdays. This pain syndrome is a common cause of chronic widespread pain and is characterized by reduced pressure pain thresholds with hyperalgesia and allodynia, nonrestorative sleep, fatigue, cognitive dysfunction, and mood disturbances. The pharmacological treatment strategies for FM include the use of antidepressants, calcium channel modulators, muscle relaxants, and analgesics but have shown limited efficacy and therapeutic adherence. Thus, researchers have been seeking potential substances (new chemical entities or through drug repositioning) that could be used for FM treatment. In this context, natural products (NPs) have been shown to be promising pharmacological tools due to the variety of their pharmacological activity and the number of molecular sites available as possible active targets. Recent clinical and preclinical studies have been conducted to verify the possible applicability © 2018 The Author(s). Licensee InTech.

The results have shown that natural products have an analgesic effect in different animal models of FM, probably by activation of inhibitory descending pathways, such as the periaqueductal gray and rostroventromedial medulla. Natural products and their secondary metabolites could therefore be a promising source for FM management. However, translational studies that seek to validate the preclinical studies are scarce, incipient, and lacking an approach focused on the traditional pharmaceutical market.
Factors Which Influence Girls’ Orientations To ICT Subjects In Schools. Evidence From Spain

The low representation of women in computer science and telecommunication engineering studies continues to be a topic of interest within the scientific community, and also a topic of concern to the policy community in Spain. The main aim of this paper is to review the literature in the Spanish language regarding the lack of interest and engagement of female secondary students in ICT-related subjects and careers. The content of the Spanish secondary educational system, the influence of stereotypical beliefs about men’s and women’s competences and attitudes towards ICTs and the way young women perceive their technology abilities are discussed in this paper. These aspects, together with a group of contextual factors specific to the context of Spain and the influence of parents and career advisors are tackled in this paper. The implications of the empirical findings and future research directions are discussed.
OCS photolytic isotope effects from first principles: sulfur and carbon isotopes, temperature dependence and implications for the stratosphere

Abstract. The isotopic fractionation in OCS photolysis is studied theoretically from first principles. UV absorption cross sections for OCS, OC 33 S, OC 34 S, OC 36 S and O 13 CS are calculated using the time-depedent quantum mechanical formalism and a recently developed ab-initio description of the photodissociation of OCS which takes into account the lowest four singlet and lowest four triplet electronic states. The calculated isotopic fractionations as a function of wavelength are in good agreement with recent measurements by Hattori et al. (2011) and indicate that photolysis leads to only a small enrichment of 34 S in the remaining OCS. The photodissociation dynamics provide strong evidence that the photolysis quantum yield is unity at all wavelengths for atmospheric UV excitation, for all isotopologues. A simple stratospheric model is constructed taking into account the main sink reactions of OCS and it is found that overall stratospheric removal slightly favors light OCS in constrast to the findings of Leung et al. (2002). These results show, based on isotopic considerations, that OCS is an acceptable source of background stratosperic sulfate aerosol in agreement with a recent model study of of Bruhl et al. (2012). The 13 C isotopic fractionation due to photolysis of OCS in the upper stratosphere is significant and will leave a clear signal in the remaining OCS making it a candidate for tracing using the ACE-FTS and MIPAS data sets.
Impact of Psychological Hardiness and Self-Monitoring on Teacher Burnout.

The purpose of this research is to examine the moderating effects of psychological hardiness and selfmonitoring on the linkage between organizational politics and teacher burnout. Totally 1344 teachers from 112 high schools chosen by random method in Ankara, Istanbul, Adana, Antalya, Samsun, Kahramanmaras, Adiyaman and Gaziantep in 20102011 spring semester, constitute sample of the research. Organizational politics were measured using the Perception of Organizational Politics (POP). Maslach Burnout Inventory, the Personal Views Survey III-R and Self-Monitoring Scale (SMS) were used to assess teacher burnout, psychological hardiness and self-monitoring respectively. In the study, the hypotheses were tested by using moderated hierarchical regression. The results of the study reveal that organizational politics is positively related to teacher burnout within high schools. Furthermore, self-monitoring strengthened the positive relationship between organizational politics and teacher burnout and psychological hardiness weakened that relationship.
YETI observations of the young transiting planet candidate CVSO 30 b

CVSO 30 is a unique young low-mass system, because, for the first time, a close-in transiting and a wide directly imaged planet candidates are found around a common host star. The inner companion, CVSO 30 b, is the first possible young transiting planet orbiting a previously known weak-lined T Tauri star. With five telescopes of the 'Young Exoplanet Transit Initiative' located in Asia, Europe and South America, we monitored CVSO 30 over three years in a total of 144 nights and detected 33 fading events. In two more seasons we carried out follow-up observations with three telescopes. We can confirm that there is a change in the shape of the fading event between different observations and that the fading event even disappears and reappears. A total of 38 fading event light curves were simultaneously modelled. We derived the planetary, stellar and geometrical properties of the system and found them slightly smaller but in agreement with the values from the discovery paper. The period of the fading event was found to be 1.36 s shorter and 100 times more precise than the previous published value. If CVSO 30 b would be a giant planet on a precessing orbit, which we cannot confirm, yet, the precession period may be shorter than previously thought. But if confirmed as a planet it would be the youngest transiting planet ever detected and will provide important constraints on planet formation and migration time-scales.
Debt and Nonlinear Fiscal Policy: Evidence from the States

Evidence from a half century of experience by states identifies nonlinearities in the effects of debt and fiscal policy on growth. Effects are Keynesian for low to moderate levels of debt and stimulus but anti Keynesian for sufficiently high levels of debt or stimulus. Results are broadly consistent with models by Barro (1999), Judd (1987), and others.
