Published: February 2017

Core Ideas
Equations with relatively simple parameters were provided to estimate soil solution phosphorus.
A regression was fitted to estimate partition coefficients of desorption isotherms.
The functions presented facilitate parameterization of existing P simulation models.
Parameters of mechanistic and empirical models to simulate nutrient dynamics in soil–plant systems are not always readily available. One way to address this problem is by developing pedotransfer functions to estimate such parameters. In this study, we derive pedotransfer functions to estimate the P contents in soil solutions (Psol) of Brazilian soils and to estimate the partition coefficient of P desorption isotherms (kd,ds). We compiled data from previous studies and developed linear and nonlinear regression models to estimate P in soil solution as a function of P extracted by Mehlich‐1 (M1) and of soil clay. A regression model was also used to obtain a relationship between the partition coefficients of sorption and desorption isotherms for soils with different physicochemical characteristics. The functions presented here facilitate parameterization of existing P simulation models for Brazilian soils that are increasingly important for both scientific research and nutrient management.
Market Reactions to Transparency International Reports on Corporate Anti-Corruption

Published: February 2017

ABSTRACT
In this paper, we examine the investor response to the issuance of Transparency International's (TI) 2012 and 2014 Transparency in Corporate Reporting: Assessing the World's Largest Companies reports. Building on prior studies of political cost-inducing events in the environmental domain, we anticipate a negative market reaction, although we argue that the adjustment will be less severe for firms rated as having better anti-corruption disclosure. Focusing on a sample of U.S. companies to control for country-level effects and to allow for comparison with the prior environmental-themed studies, we document a significantly negative market reaction to the first TI report issuance. Although also negative, the market reaction to the 2014 report was not statistically significant. However, we also document that, as expected, market adjustments differ significantly across subgroups based on anti-corruption disclosure in both time periods. These results hold controlling for other factors potentially influencing investor perceptions of exposure to the report issuances. In general, our results are consistent with the prior studies and indicate that the market is savvy to political cost exposures arising from non-environmental events. The findings also suggest that TI's efforts may be increasing stakeholder pressure for corporate anti-corruption performance, but we caution that further investigation of the relation between disclosure and underlying performance in the corruption domain is warranted.

OBJECTIVE
To determine whether plasma levels of advanced glycation end products and oxidation products play a role in the development of atherosclerosis in patients with type 2 diabetes (T2D) over nearly 10 years of the VA Diabetes Trial and Follow-up Study.

RESEARCH DESIGN AND METHODS
Baseline plasma levels of methylglyoxal hydroimidazolone, Nε-carboxymethyl lysine, Nε-carboxyethyl lysine (CEL), 3-deoxyglucosone hydroimidazolone and glyoxal hydroimidazolone (G-H1), 2-aminoadipic acid (2-AAA), and methionine sulfoxide were measured in a total of 411 participants, who underwent ultrasound assessment of carotid intima-media thickness (CIMT), and computed tomography scanning of coronary artery calcification (CAC) and abdominal aortic artery calcification (AAC) after an average of 10 years of follow-up.

RESULTS
In risk factor–adjusted multivariable regression models, G-H1 was associated with the extent of CIMT and CAC. In addition, 2-AAA was strongly associated with the extent of CAC, and CEL was strongly associated with the extent of AAC. The combination of specific advanced glycation end products and oxidation products (G-H1 and 2-AAA) was strongly associated with all measures of subclinical atherosclerosis.

CONCLUSIONS
Specific advanced glycation end products and metabolic oxidation products are associated with the severity of subclinical atherosclerosis over the long term and may play an important role in the “negative metabolic memory” of macrovascular complications in people with long-standing T2D.

Abstract
Introduction. TIn a situation characterized by a low birth rate and a highly competitive education market, increasing attention is currently being paid not only to students' level of education, but also to their competencies and predisposition. Consequently, the purpose of this study is to analyze differences in morphological features among physical education students as compared with students of other subjects at the Faculty of Physical Education and Sport (WWFiS) in Biała Podlaska. Material and methods. This study is based on anthropometric data from 165 first-year female students at WWFiS in Biała Podlaska. Analysis was conducted on a selection of students divided into groups based on their study profile. Using the technique developed by Martin and Saller, measurements were taken of the anthropometric features required to determine BMI and WHR indexes and to estimate body tissue composition. The following were used to characterize the collected variables: sample size (n) arithmetic mean ( ) and standard deviation (SD). Differences among the groups with regard to the features being measured were assessed using ANOVA variation analysis and NIR testing. Results. The study did not confirm reports from other authors concerning analysis of connections between bodily structure and education profile. Thus, it should be concluded that a student's physique plays only a small role in their being selected to study physical education. Conclusions. The differences noted between the groups should rather be interpreted as owing to environmental differences in the lifestyles of the girls in question, rather than to recruitment procedures and, by extension, education profile.

Abstract
Blazars are an extreme subclass of active galactic nuclei. Their rapid variability, luminous brightness, superluminal motion, and high and variable polarization are probably due to a beaming effect. However, this beaming factor (or Doppler factor) is very difficult to measure. Currently, a good way to estimate it is to use the timescale of their radio flares. In this Letter, we use multiwavelength data and Doppler factors reported in the literature for a sample of 86 flaring blazars detected by Fermi to compute their intrinsic multiwavelength data and intrinsic spectral energy distributions and investigate the correlations among observed and intrinsic data. Quite interestingly, intrinsic data show a positive correlation between luminosity and peak frequency, in contrast with the behavior of observed data, and a tighter correlation between γ-ray luminosity and the lower-energy ones. For flaring blazars detected by Fermi, we conclude that (1) observed emissions are strongly beamed; (2) the anti-correlation between luminosity and peak frequency from the observed data is an apparent result, the correlation between intrinsic data being positive; and (3) intrinsic γ-ray luminosity is strongly correlated with other intrinsic luminosities.

Abstract
The most popular model for short gamma-ray bursts (sGRBs) involves the coalescence of binary neutron stars. Because the progenitor is actually hidden from view, we must consider under which circumstances such merging systems are capable of producing a successful sGRB. Soon after coalescence, winds are launched from the merger remnant. In this paper, we use realistic wind profiles derived from global merger simulations in order to investigate the interaction of sGRB jets with these winds using numerical simulations. We analyze the conditions for which these axisymmetric winds permit relativistic jets to break out and produce an sGRB. We find that jets with luminosities comparable to those observed in sGRBs are only successful when their half-opening angles are below ≈20°. This jet collimation mechanism leads to a simple physical interpretation of the luminosities and opening angles inferred for sGRBs. If wide, low-luminosity jets are observed, they might be indicative of a different progenitor avenue such as the merger of a neutron star with a black hole. We also use the observed durations of sGRB to place constraints on the lifetime of the wind phase, which is determined by the time it takes the jet to break out. In all cases we find that the derived limits argue against completely stable remnants for binary neutron star mergers that produce sGRBs.

ABSTRACT

Aim
Type 2 diabetes mellitus (DM2) is a chronic disease caused by the underproduction of insulin in the organism and it is considered a risk factor to periodontal disease.

Materials and methods
This study performed a cross-sectional research on the main oral changes in patients with DM2 and nondiabetics, in Passo Fundo, Rio Grande do Sul, Brazil. The sample included 116 patients examined at the Diabetes Outpatient Clinic of the School of Medicine of the University of Passo Fundo (UPF) and 134 nondiabetic patients examined at the Examinations, Triage, and Emergency Sector of the School of Dentistry of UPF. Inclusion criteria for the study were patients over 35-years old, diagnosed with DM2 for more than 2 years. The same criteria were used for the control group, except for the presence of diabetes. Data collected were analyzed by Statistical Package for the Social Sciences 18.0 for Windows™ software and the Chi-square test at 5% significance. This study showed that, overall, oral lesions were more prevalent in diabetic patients.

Results
The stomatological manifestations observed more frequently in such patients were pseudomembranous candidiasis, lichen planus, lingual varices, xerostomia, and prosthetic stomatitis (p > 0.001).

Conclusion
Therefore, based on the sample investigated, it is concluded that patients with DM2 present higher prevalence of oral lesions when compared with nondiabetics.

Clinical significance
It is important for the dentist to know about oral lesions because they may allow either early diagnosis in patients unaware of this condition or help diagnosing a potential decompensation. Moreover, oral lesions may represent a potential gateway for infectious agents, and the dentist may restrain this condition by performing treatment as early as possible.

Radiofrequency Glow Discharge as a Mode of Disinfection for Elastomeric Impression Materials
Authors: Alani Mathew M , Reba PB , Mathew Susan , Nair KN Velayudhan , Haridas Sayij , Thomas Sherin A 
Published: February 2017

ABSTRACT

Introduction
Prosthodontic practice involves procedures in which impressions of the maxillary and mandibular arches are mandatory. Cross infection is one of the major problems that can occur in regular dental practice. Every dentist should take utmost care to prevent cross infection as oral cavity is the source of variety of microorganisms which can often cause diseases that can be fatal. Although precautions, such as wearing of gloves and mask, sterilization of instruments are given importance, the need for disinfection of impressions is often neglected. Hence, the aim of the study was to assess the disinfection potential of radiofrequency glow discharge (RGD) by microbiological studies.

Materials and methods
Disinfection potential of RGD on addition silicone (Reprosil, Dentsply, Milford DE, USA) was assessed. Total sample size was 20. Samples were divided into two groups of 10 each. Group I – control group and group II – RGD-treated group. Main groups were subdivided into subgroups A and B. Data collected were analyzed.

Results
The RGD-treated samples were found to be culture sterile which meant that there were no signs of growth of any organisms, thus proving the disinfection potential of RGD.

Conclusion
From this study, we can conclude that RGD is a very rapid and handy device, which can disinfect saliva contaminated elastomeric impression material surfaces.

Clinical significance
When compared with the difficulties and lack of efficiency encountered in disinfecting impressions by immersion and spray atomization, RGD can be very handy in dental clinics, as it is a very rapid and convenient method for infection control.

Large-scale gravity wave perturbations in the mesopause region above Northern Hemisphere midlatitudes during autumnal equinox: a joint study by the USU Na lidar and Whole Atmosphere Community Climate Model
Authors: Cai Xuguang , Yuan Tao , Liu Han-Li 
Published: February 2017

Abstract. To investigate gravity wave (GW) perturbations in the midlatitude mesopause region during boreal equinox, 433 h of continuous Na lidar full diurnal cycle temperature measurements in September between 2011 and 2015 are utilized to derive the monthly profiles of GW-induced temperature variance, T′2, and the potential energy density (PED). Operating at Utah State University (42° N, 112° W), these lidar measurements reveal severe GW dissipation near 90 km, where both parameters drop to their minima (∼ 20 K2 and ∼ 50 m2 s−2, respectively). The study also shows that GWs with periods of 3–5 h dominate the midlatitude mesopause region during the summer–winter transition. To derive the precise temperature perturbations a new tide removal algorithm suitable for all ground-based observations is developed to de-trend the lidar temperature measurements and to isolate GW-induced perturbations. It removes the tidal perturbations completely and provides the most accurate GW perturbations for the ground-based observations. This algorithm is validated by comparing the true GW perturbations in the latest mesoscale-resolving Whole Atmosphere Community Climate Model (WACCM) with those derived from the WACCM local outputs by applying this newly developed tidal removal algorithm.

Published: February 2017

This paper aims to identify factors that are considered by the first year undergraduate students from Faculty of Arts and Social Sciences (FASS), University of Malaya in course selection process in two different stages namely pre-entry and post-entry. Findings from this study reveals that in pre-entry selection criteria, ‘teacher’ and ‘family’ factors appears to be more important. ‘Labour market consideration’ only appears to be the third important factor in this stage. These three factors collectively explains approximately 54 percent of the variation in pre-entry selection criteria. In post-entry selection criteria, ‘peers influence’ , ‘orientation week’ and ‘limited choices’ factors emerged as important dimensions. These three factors in turn collectively explains approximately 49 percent of the variation in post-entry selection criteria. ‘Labour market consideration’ emerges only as the second last important factor in post-entry selection criteria.

Do syntopic host species harbour similar symbiotic communities? The case ofChaetopterusspp. (Annelida: Chaetopteridae)
Authors: Britayev Temir A. , Mekhova Elena , Deart Yury , Martin Daniel 
Published: February 2017

To assess whether closely related host species harbour similar symbiotic communities, we studied two polychaetes,Chaetopterussp. (n = 11) andChaetopteruscf.appendiculatus(n = 83) living in soft sediments of Nhatrang Bay (South China Sea, Vietnam). The former harboured the porcellanid crabsPolyonyxcf.heokandPolyonyxsp., the pinnotherid crabTetriassp. and the tergipedid nudibranchPhestillasp. The latter harboured the polynoid polychaeteOphthalmonoe pettiboneae, the carapid fishOnuxodon fowleriand the porcellanid crabEulenaios cometes, all of which, exceptO. fowleri, seemed to be specialized symbionts. The species richness and mean intensity of the symbionts were higher inChaetopterussp. than inC.cf.appendiculatus(1.8 and 1.02 species and 3.0 and 1.05 individuals per host respectively). We suggest that the lower density ofChaetopterussp. may explain the higher number of associated symbionts observed, as well as the 100% prevalence (69.5% inC.cf.appenciculatus). MostChaetopterussp. harboured two symbiotic species, which was extremely rare inC.cf.appendiculatus, suggesting lower interspecific interactions in the former. The crab and nudibranch symbionts ofChaetopterussp. often shared a host and lived in pairs, thus partitioning resources. This led to the species coexisting in the tubes ofChaetopterussp., establishing a tightly packed community, indicating high species richness and mean intensity, together with a low species dominance. In contrast, the aggressive, strictly territorial species associated withC.cf.appendiculatusestablished a symbiotic community strongly dominated by single species and, thus, low species richness and mean intensity. Therefore, we suggest that interspecific interactions are determining species richness, intensity and dominance, while intraspecific interactions are influencing only intensity and abundance. It is possible that species composition may have influenced the differences in community structure observed. We hypothesize that both host species could originally be allopatric. The evolutionary specialization of the symbiotic communities would occur in separated geographical areas, while the posterior disappearance of the existing geographical barriers would lead to the overlapped distribution.

ImportanceHow epilepsy may promote cardiovascular disease remains poorly understood.ObjectiveTo estimate the odds of new-onset cardiovascular events (CVEs) over 6 years in older people with vs without epilepsy, exploring how enzyme-inducing antiseizure medications (EIASMs) and traditional cardiovascular risk factors mediate these odds.Design, Setting, and ParticipantsThis was a prospective cohort study using the comprehensive cohort of the Canadian Longitudinal Study on Aging (CLSA), with 6 years of follow-up (2015-2021, analysis performed in December 2023). The CLSA is an ongoing, national study of 51 338 adults aged 45 to 85 years at baseline who are recruited in Canada. The comprehensive cohort includes 30 097 individuals living near 1 of 11 data collection centers. Participation in the CLSA was voluntary; participation rate was 45%. Among those in the comprehensive cohort, individuals reporting no previous history of CVEs (ie, stroke, transient ischemic attack [TIA], or myocardial infarction [MI]) at baseline were excluded. No other exclusion criteria were applied. A total of 86% of participants completed follow-up.ExposureLifetime history of epilepsy.Main Outcomes and MeasuresThe primary outcome was new-onset CVEs over 6 years. Secondary outcomes were new-onset strokes, TIAs, and MIs. Logistic models were fitted for these outcomes as a function of epilepsy, age, sex, household income, and education level. Mediation analyses were conducted for strong EIASM use, weak EIASM use, Framingham score, Physical Activity Scale for the Elderly (PASE) score, and waist to hip ratio.ResultsAmong the 30 097 individuals in the comprehensive cohort, a total of 27 230 individuals (mean [SD] age, 62.3 [10.1] years; 14 268 female [52.4%]) were included, 431 with a lifetime history of epilepsy. New-onset CVEs were more likely in epilepsy, with an adjusted odds ratio of 2.20 (95% CI, 1.48-3.27). The proportion of the effect of epilepsy on new-onset CVEs was mediated as follows by each of the following variables: strong EIASM use, 24.6% (95% CI, 6.5%-54.6%), weak EIASM use, 4.0% (95% CI, 0.8%-11.0%), Framingham score, 1.4% (95% CI, −1.6% to 4.5%), PASE score, 3.3% (95% CI, 1.4%-6.8%), and waist to hip ratio, 1.6% (95% CI, 0.4%-3.7%).Conclusions and RelevanceResults of this cohort study reveal that epilepsy was associated with new-onset CVEs. Nearly one-third of this association can be explained by EIASMs. These findings should be considered when choosing an antiseizure medication for a person at risk for cardiovascular disease.
