Abstract
Watson, AM, Brickson, SL, Prawda, ER, and Sanfilippo, JL. Short-term heart rate recovery is related to aerobic fitness in elite intermittent sport athletes. J Strength Cond Res 31(4): 1055–1061, 2017—Although heart rate recovery (HRR) has been suggested as a measure of fitness, minimal data exist among athletes. The purpose of this study was to determine if HRR is related to aerobic fitness in elite athletes and whether this relationship is influenced by sex or body composition. Eighty-four collegiate athletes (45 male athletes) underwent body fat percentage (BF%) determination by dual-energy x-ray absorptiometry and maximal treadmill testing followed by 5 minutes of recovery. V̇o
2max and heart rate (HRmax) were determined, and HRR was calculated as a percentage of HRmax at 10 seconds, 30 seconds, and 1, 2, 3, 4, and 5 minutes after test completion. After stratifying by sex, participants were grouped as high fit or low fit based on V̇o
2max median split. Heart rate recovery was compared between sexes and fitness level at each time point. Multivariable regression analysis was used to identify independent predictors of HRR using V̇o
2max, BF%, and sex as covariates. Heart rate recovery did not differ significantly between sexes and was faster among high-fit participants at 10 and 30 seconds, but at no other time. V̇o
2max was significantly correlated with HRR at 10 and 30 seconds (r = −0.34, p < 0.001 and r = −0.28, p = 0.008) only. After controlling for BF% and sex, V̇o
2max remained significantly associated with HRR at 10 seconds (p = 0.007) but not at 30 seconds (p = 0.067) or any time thereafter. Aerobic capacity is related to faster HRR during the first 30 seconds only, suggesting that only very short term HRR should be used as a measure of aerobic fitness in intermittent sport athletes.

Differential Contributions of Olfactory Receptor Neurons in a Drosophila Olfactory Circuit

Published: July 2016

AbstractThe ability of an animal to detect, discriminate, and respond to odors depends on the functions of its olfactory receptor neurons (ORNs). The extent to which each ORN, upon activation, contributes to chemotaxis is not well understood. We hypothesized that strong activation of each ORN elicits a different behavioral response in theDrosophila melanogasterlarva by differentially affecting the composition of its navigational behavior. To test this hypothesis, we exposedDrosophilalarvae to specific odorants to analyze the effect of individual ORN activity on chemotaxis. We used two different behavioral paradigms to analyze the chemotaxis response of larvae to odorants. When tested with five different odorants that elicit strong physiological responses from single ORNs, larval behavioral responses toward each odorant differed in the strength of attraction as well as in the composition of discrete navigational elements, such as runs and turns. Further, behavioral responses to odorants did not correlate with either the strength of odor gradients tested or the sensitivity of each ORN to its cognate odorant. Finally, we provide evidence that wild-type larvae with all ORNs intact exhibit higher behavioral variance than mutant larvae that have only a single pair of functional ORNs. We conclude that individual ORNs contribute differently to the olfactory circuit that instructs chemotactic responses. Our results, along with recent studies from other groups, suggest that ORNs are functionally nonequivalent units. These results have implications for understanding peripheral odor coding.

Published: July 2016

Background and aims
Problem and pathological gambling have been associated with elevated rates of both Axis-I and Axis-II psychiatric disorders. Although both problem gambling and psychiatric disorders have been reported as being more prevalent among lower income vs. middle/higher income groups, how income might moderate the relationship between problem-gambling severity and psychopathology is incompletely understood. To examine the associations between problem-gambling severity and psychopathology in lower income and middle/higher income groups.

Methods
Data from the first wave of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) (n = 43,093) were analyzed in adjusted logistic regression models to investigate the relationships between problem-gambling severity and psychiatric disorders within and across income groups.

Results
Greater problem-gambling severity was associated with increased odds of multiple psychiatric disorders for both lower income and middle/higher income groups. Income moderated the association between problem/pathological gambling and alcohol abuse/dependence, with a stronger association seen among middle/higher income respondents than among lower income respondents.

Discussion and conclusions
The findings that problem-gambling severity is related to psychopathology across income groups suggest a need for public health initiatives across social strata to reduce the impact that problem/pathological gambling may have in relation to psychopathology. Middle/higher income populations, perhaps owing to the availability of more “disposable income,” may be at greater risk for co-occurring gambling and alcohol-use psychopathology and may benefit preferentially from interventions targeting both gambling and alcohol use.

ABSTRACTBreastfeeding initiation and duration are decreased in adolescent mothers compared to older mothers. A prospective descriptive cohort design was used to explore personal, social, cultural, and infant factors that explain and predict breastfeeding initiation and maintenance at 4 weeks postpartum. Adolescent mothers (N = 120) were recruited at prenatal clinics in Thailand. Data were collected at enrollment, during birth hospitalization (N = 102), and at 4 weeks postpartum (N = 96). Findings revealed breastfeeding attitudes, social support, and cultural beliefs about “being a good mother” were positively correlated with breastfeeding initiation. Furthermore, breastfeeding attitudes and social support were significant positive predictors of exclusive breastfeeding (both p ≥ .01) continuation through 4 weeks, whereas infant temperament was a significant negative predictor (p ≥ .04). Maternal competence at 4 weeks postpartum was also positively correlated with exclusive breastfeeding continuation.

Published: July 2016

Background: An antiplaque agent with minimal side effects that can be used as an effective adjunct to mechanical plaque control is needed. The current study is designed to evaluate efficacy of triphala (TRP) mouthwash in reduction of plaque and gingivitis.Methods: Ninety individuals with chronic generalized gingivitis were randomly assigned to three groups: 1) group I, placebo mouthwash; 2) group II, TRP mouthwash; and 3) group III, chlorhexidine (CHX) mouthwash. All individuals were instructed to rinse with their respective mouthwash twice daily. 1) Plaque index (PI); 2) gingival index (GI); 3) oral hygiene index‐simplified (OHI‐S); and 4) microbiologic colony counts were recorded at baseline and at 7, 30, and 60 days.Results: All three groups showed gradual reduction in PI, GI, and OHI‐S levels from baseline to 7, 30, and 60 days. There was also significant reduction in microbial counts in all groups at all time intervals except in group I. A significant difference was noticed with respect to reduction in PI, GI, OHI‐S, and microbiologic counts in group I compared with groups II and III. However, no significant differences were found between groups II and III for any parameters at any time intervals.Conclusions: TRP mouthwash was found to decrease inflammatory parameters from baseline to follow‐up intervals. Because improvement in gingivitis was comparable with that of CHX mouthwash, TRP mouthwash can be considered a potential therapeutic agent in the treatment of gingivitis.
Mechanical-Damage Characterization in Proppant Packs by Use of Acoustic Measurements

Published: July 2016

SummaryThe strength and conductivity of proppant packs are key parameters for assessing proppant-pack performance. Mechanical damage in the propping agents, which leads to compaction and crushing, significantly reduces the conductivity of the proppant pack. Mechanical damage of proppants is usually analyzed by use of crush tests. However, measurements from these tests remain questionable because of discrepancies in procedures and test results. Therefore, a need emerges to develop techniques for characterizing the properties and mechanical damage in proppant packs.In this paper, we introduced a new technique that is based on interpretation of acoustic measurements from a granular effective-media model to quantify mechanical damage in propping agents. We performed uniaxial compression tests in the laboratory and measured the compressional- and shear-wave velocities in proppant packs loaded at axial stresses ranging from 10 to 110 MPa. After unloading the tests in which maximum axial stresses of 28, 55, 69, 97, and 110 MPa were applied, we conducted sieve analysis on the proppant packs. We applied an effective-medium theory modeled after the Hertz-Mindlin granular contact model to approximate the effective elastic properties. We then calibrated the model by use of the elastic properties estimated from the experimental measurements to characterize the mechanical damage of the proppant packs.We observed that the increase in grain-to-grain contact as the axial stress increases results in compaction and crushing in the proppant pack. We showed that the compaction effects and elastic and plastic behaviors in the stress–strain profile of the proppant pack were in agreement with the analysis of fines generated at different stress levels. The combined effect of compaction and crushing resulted in a reduction of porosity and, consequently, decreased the compressional- and shear-wave velocities of the proppant pack. The Hertz-Mindlin model showed a good approximation of the effective elastic properties estimated from the acoustic-wave velocities when calibrated with the pressure-dependent grain contact and the fraction of nonslipping grains as parameters. We demonstrated that the calibrated parameters can be correlated with the mechanical damage in the proppant pack. The characterization of mechanical damage in proppant packs can improve the design of the propping agents and quantification of proppant performance. Furthermore, the laboratory procedure can be extended to the use of borehole acoustic measurements in providing a real-time in-situ assessment of proppant performance.
Workforce Involvement in Safety Programme

Published: July 2016

Abstract
For decades the management literature has been advocating the merits of consulting employees, more participation and more democratic supervision in the decision making of organisations. In the last ten years, the principles of workforce involvement have been applied in a limited way to areas such as safety management in the offshore industry. The current industry safety performance has plateaued, in order to achieve a step change operators and contractors have realised they need to utilise the experience, knowledge and ideas of the workforce to bring about a culture shift in attitudes to safety. Shell Expro decided to implement the principles of workforce involvement in a comprehensive way to make a step change in safety performance. To do this three pilot studies were set up (N = 279) to involve the workforce directly in identifying their safety concerns then helping them develop and implement their own solutions. External factors created difficulties that were largely overcome, demonstrating that the process outlined in the paper, if managed correctly, can improve safety performance and raise morale in a period of cost reduction and job uncertainty. Based on what the involvement process has achieved so far, the programme or some variant has now been rolled out across all the company's locations covering N = 1892 members of the workforce.
Managing the Risk at the Interface
Authors: Thom Gordon 
Published: July 2016

ABSTRACT
From the very inception of individual company health and safety management systems, there has been an awareness of the increased risk associated with work undertaken in conjunction with third parties. In by far the majority of cases, this occurs between client and contractor and, in the oil and gas industry, gives rise to the traditional operator/contractor interface, with all its attendant safety issues.
There was a tendency in the past for the operator to manage these interface issues by insisting that the contractor simply worked in accordance with the requirements of the client health and safety management system. This approach did not adequately manage the risks at the interface and completely ignored the contractors’ legal and moral responsibilities for ensuring the provision of safe systems of work for contractor personnel.
Changes in contracting strategies and a more enlightened approach to the improvement of safety performance across the whole industry has lead to an appreciation that:
the risk at the interface is not confined to operator/contractor relationships; shared activities between any parties, whether contractually linked or not, may well give rise to increased risk, which requires to be managed. where any one party's employees, assets or reputation may be at risk from another, whilst undertaking shared activities, then the respective responsibilities and arrangements for the management of these risks must be agreed and documented. the imposition of one party's health and safety management system upon the other(s) is no guarantee of effective management of risk at the interface.
In the spirit of sharing best practice, this paper presents the outcome of over a year's work by a Step Change in Safety Task Group in producing industry guidance for health and safety management systems interfacing. The paper will address:

Low Effective Surface Area Explains Slow Oxidation of Co‐Granulated Elemental Sulfur
Authors: Zhao Cuicui , Degryse Fien , Gupta Vadakattu , McLaughlin Mike J. 
Published: July 2016

Core Ideas
The oxidation of co‐granulated elemental S (ES) was slower than that of powdered ES.
Bacterial abundance and community composition in the soil localized around a granular fertilizer (diammonium phosphate [DAP] + ES [10%]) differed from that in the soil with powdered DAP + ES (thoroughly mixed).
Differences in bacterial abundance and community composition could not explain the differences in the percentage of ES oxidized between co‐granulated and powdered ES.
The reduction in effective available surface area of ES particles corresponded to the slower oxidation of co‐granulated ES compared to powdered ES.
Elemental S (ES) is commonly used as a S fertilizer but must be oxidized to sulfate for plant uptake. Oxidation of ES in co‐granulated fertilizers has been shown to be slower than that of powdered ES mixed with soil. We hypothesized that the slow oxidation is due to limited access of S oxidizers to the interior of the granule. To test this hypothesis, an experiment was conducted to compare chemical properties and bacterial populations in soil in the vicinity of a granule (diammonium phosphate [DAP] + ES [10%]) and in soil mixed with powdered DAP + ES. Copy numbers of 16S ribosomal ribonucleic acid (rRNA) genes and of a functional gene soxB were quantified to indicate the abundance of total and S‐oxidizing bacteria, respectively, and the total bacterial community composition was analyzed by terminal restriction fragment length polymorphism (TRFLP). After 20 wk of incubation, 42% of the co‐granulated ES was oxidized compared to 95% for the powdered ES. The soil pH dropped by 1.0 and 1.7 units for the granular and powdered treatments, respectively. We observed significant changes in bacterial abundance and community composition during incubation. However, none of the alterations in chemical properties and bacterial populations could explain the adverse effects of granulation on ES oxidation. The difference in ES oxidation rate between the co‐granulated and powdered ES corresponded to the difference in surface area of the granule and of the individual ES particles, quantitatively corroborating that the available surface area exposed to S‐oxidizing microorganisms is the limiting factor for co‐granulated ES oxidation.

Core Ideas
Soil acidity limits crop production in tropical regions.
Soil amendments mixture can be a strategy to alleviate subsoil acidity.
Subsoil profile acidity reduces common bean grain yield.
The movement of surface‐applied lime to subsurface soil layers is slow, and, consequently, liming requires a long period of time to become effective. Thus, it is important to develop strategies to increase the efficiency of acidity amendments practices in order to improve the chemical properties of tropical acid soils in no‐till systems. The aim of this study was to evaluate the effects of applying mixtures of silicate, lime, and phosphogypsum to the soil surface in tropical no‐till systems on soil chemical properties and leaf nutrient concentrations, yield components, and grain yield of the common bean (Phaseolus vulgaris L.). A field experiment was performed during two growing seasons (2004 and 2005) in a field with Typic Acrustox soils. Among the treatments, the silicate–phosphogypsum mixture was more effective for ameliorating soil acidity at a depth of 0 to 0.20 m over a short period of time (6 mo). The application of soil amendments separately or in mixtures increased the soil pH to 0.40 m depth 18 mo after application. Combining the surface application of phosphogypsum with lime and/or silicate effectively increased the NO3−–N, SO42−–S, and Ca2+ levels at soil depths of up to 0.40 m over a relatively short period of time, resulting in a higher base saturation in the deepest layer evaluated (0.20–0.40 m). Compared with the control treatment, the mixtures of soil acidity amendments and phosphogypsum resulted in greater Ca, S, and Si concentrations in the leaves and increased the grain yield of the common bean by >22% over two growing seasons. Long‐term studies are required to establish the frequency of reapplication and the residual effects of soil amendment mixtures.
