Abstract
Mercury contamination in the Great Lakes continues to have important public health and wildlife ecotoxicology impacts, and atmospheric deposition is a significant ongoing loading pathway. The objective of this study was to estimate the amount and source-attribution for atmospheric mercury deposition to each lake, information needed to prioritize amelioration efforts. A new global, Eulerian version of the HYSPLIT-Hg model was used to simulate the 2005 global atmospheric transport and deposition of mercury to the Great Lakes. In addition to the base case, 10 alternative model configurations were used to examine sensitivity to uncertainties in atmospheric mercury chemistry and surface exchange. A novel atmospheric lifetime analysis was used to characterize fate and transport processes within the model. Model-estimated wet deposition and atmospheric concentrations of gaseous elemental mercury (Hg(0)) were generally within ∼10% of measurements in the Great Lakes region. The model overestimated non-Hg(0) concentrations by a factor of 2–3, similar to other modeling studies. Potential reasons for this disagreement include model inaccuracies, differences in atmospheric Hg fractions being compared, and the measurements being biased low. Lake Erie, downwind of significant local/regional emissions sources, was estimated by the model to be the most impacted by direct anthropogenic emissions (58% of the base case total deposition), while Lake Superior, with the fewest upwind local/regional sources, was the least impacted (27%). The U.S. was the largest national contributor, followed by China, contributing 25% and 6%, respectively, on average, for the Great Lakes. The contribution of U.S. direct anthropogenic emissions to total mercury deposition varied between 46% for the base case (with a range of 24–51% over all model configurations) for Lake Erie and 11% (range 6–13%) for Lake Superior. These results illustrate the importance of atmospheric chemistry, as well as emissions strength, speciation, and proximity, to the amount and source-attribution of mercury deposition.
‘Eeveryone’s magical and everyone’s important’: Karaoke community and identity in an Aamerican gay bar
Authors: Kelley Jamey 
Published: July 2016

Abstract
Although community music activities can take many forms, a ‘participatory ethos’ is central to most community music endeavours. Karaoke singing, the practice of public singing to an accompaniment track, which on the surface appears to emphasize solo performance, has the potential to provide a communal flow experience that could be described as community music within certain contexts. Karaoke singing has become a musical practice and form of entertainment around the world and in many types of settings. The case study used for this investigation is a karaoke culture at an LGBT establishment in a city on the American west coast. This study focuses on the formation of community as well as identity through karaoke performance. Additionally, the application of Turino’s framework of participatory and presentational performance was used to examine how musical behaviours may encourage the formation of community and identity. Findings within this case study reveal the importance of the roles of the participants, the role of the facilitator, the agency of the individual, the fixity of musical forms, and musical texture to promote participatory experiences.
Musical activity across the lifespan as it contributes to quality of life
Authors: White Mary Terrell 
Published: July 2016

Abstract
As the baby-boomer generation ages, attention to maintaining quality of life is receiving renewed attention. Involvement in social activity, including the performing arts, is increasingly seen as offering opportunities for meaningful social engagement as well as promoting physical and emotional health. This article examines the role of musical activity for older adults in a small town in Ohio, exploring what musicians value about their musical activities and how they believe their involvement in music contributes to their quality of life. Respondents affirm that music confers benefits of enjoyment, intellectual and physical stimulation, and meaningful engagement in their community. These findings are consistent with factors previously identified as essential to the quality of life of older individuals, and are strengthened by their similarity to an earlier, much larger study of benefits perceived by older musicians participating in New Horizons ensembles.

Johnson, EC, Pryor, RR, Casa, DJ, Ellis, LA, Maresh, CM, Pescatello, LS, Ganio, MS, Lee, EC, and Armstrong, LE. Precision, accuracy, and performance outcomes of perceived exertion vs. heart rate guided run-training. J Strength Cond Res 31(3): 630–637, 2017—The purpose of this investigation was to compare run-prescription by heart rate (HR) vs. rating of perceived exertion (RPE) during 6 weeks to determine which is superior for consistent achievement of target intensities and improved performance. Forty untrained men participated in this laboratory-controlled and field-controlled trial. Participants were divided into heart rate (HRTG) and rating of perceived exertion training groups (RPETG). All underwent maximal-graded exercise testing and a 12-minute run test before and after training. Intensity was prescribed as either a target HR or RPE that corresponded to 4 relative intensity levels: 45, 60, 75, and 90% V̇o
2 reserve (V̇o
2R). Mean exercise intensity over the 6 weeks did not differ between HRTG (65.6 ± 7.2%HRR) and RPETG (61.9 ± 9.0%HRR). V̇o
2max (+4.1 ± 2.5 ml·kg−1·min−1) and 12 minutes run distance (+240.1 ± 150.1 m) improved similarly in HRTG and RPETG (p > 0.05). HRTG displayed lower coefficients of variation (CV) (5.9 ± 4.1%, 3.3 ± 3.8%, and 3.0 ± 2.2%) and %error (4.1 ± 4.7%, 2.3 ± 4.1% and 2.6 ± 3.2%) at 45, 60, and 75% V̇o
2R compared with RPETG (CV 11.1 ± 5.0%, 7.7 ± 4.1% and 5.6 ± 3.2%; all p < 0.005) %error (15.7 ± 9.2%, 10.6 ± 9.2% and 6.7 ± 3.2%; all p < 0.001), respectively. Overall, HR-prescribed and RPE-prescribed run-training resulted in similar exercise intensity and performance outcomes over 6 weeks. Differences in the CV and %error suggest use of HR monitoring for individuals that are new to running as it improves precision and accuracy but does not increase performance improvements across 6 weeks.

AbstractKim, T-G, Kim, E-K, and Park, J-C. Immediate effects of sports taping applied on the lead knee of low- and high-handicapped golfers during golf swing.J Strength Cond Res31(4): 981–989, 2017—Elite golf athletes suffer from various musculoskeletal injuries due to repeated golf swings. Repetitive varus moment during golf swing has been suggested as a possible cause of injuries to the lead knee. The aim of this study was to objectively and quantitatively evaluate the immediate effects of sports taping on the lead knee of elite golfers to restrict varus moment. Thirty-one elite golfers were assigned to the low- (LHG,n= 15) or high-handicapped group (HHG,n= 16). Using 3-dimensional motion analysis, the lead knee position on the frontal plane with and without rigid taping (RT), elastic taping (ET), and placebo taping was identified in 4 separate phases by the 5 events of golf swing as follows: the peak of the backswing (E1), parallel to the ground during downswing (E2), ball impact (E3), parallel to the ground during follow-through (E4), and finish (E5). The LHG when using a driver club had decreased movement toward knee varus with RT and ET than that without it from E1 to E2 (p= 0.001). The LHG when using a 5-iron club decreased movement toward knee varus with RT than that without it from E1 to E2 (p= 0.006) and from E2 to E3 (p= 0.019). The HHG when using a driver club had decreased movement toward knee varus with RT from E1 to E2 (p= 0.014). Sports taping may be helpful for elite golfers in terms of reducing varus moment of the lead knee during the downswing and be useful for the development of preventive strategies for golf-related knee injuries.

Abstract
Scott, BR, Hodson, JA, Govus, AD, and Dascombe, BJ. The 30-15 Intermittent Fitness Test: can it predict outcomes in field tests of anaerobic performance? J Strength Cond Res 31(10): 2825–2831, 2017—This study determined whether a composite assessment of intermittent fitness could be used to quantify performance in several anaerobic tasks. Fifty-two male recreational athletes (age: 24.3 ± 4.4 years; body mass: 85.1 ± 12.2 kg; height: 180.5 ± 7.0 cm) were recruited from various team sports. Participants completed a battery of field tests to assess sprinting speed (40-m sprint), acceleration ability (10-m sprint), change of direction speed (505 test), anaerobic capacity (300-m shuttle), lower-body power (vertical jump), and repeated-sprint ability and the 30-15 Intermittent Fitness Test to determine the velocity of intermittent fitness (VIFT). Relationships between anaerobic tests and VIFT were quantified via Pearson product-moment correlations, and a 2-predictor model multiple linear regression estimated the predictive relationships between the exercise tests and the VIFT. Multiple linear regression showed that VIFT significantly predicted 56, 51, 44, 36, 12, and 1% of the variance in the 300-m shuttle, repeated sprint, 505- and 40-m sprint, vertical jump, and 10-m sprint tests, respectively. The 2-predictor model determined the 300-m shuttle, and repeated-sprint performance accounted for 67% of the variance in VIFT. These findings highlight that various anaerobic characteristics contribute to the intermittent fitness qualities that are quantified through VIFT. More specifically, these data indicate that VIFT is useful for tracking performance in tasks largely determined by anaerobic capacity, but may not be a good predictor of brief all-out sprinting and jumping efforts.

ABSTRACTIT IS GENERALLY ACCEPTED THAT VOLUNTARY WEIGHT CUTTING BEFORE ENTERING A COMPETITION HAS BECOME A HABITUAL PRACTICE AMONG COMBAT SPORTS ATHLETES. APART FROM ANTIDOPING REGULATIONS BANNING THE USE OF DIURETICS, THE OLYMPIC GOVERNING BODY HAS NOT ESTABLISHED POLICIES AIMED TO MONITOR AGGRESSIVE WEIGHT CUTTING. IT IS EXTREMELY IMPORTANT FOR COMBAT SPORTS ATHLETES TO REDUCE ADVERSE AND HEALTH-THREATENING SIDE EFFECTS EVOKED BY DIFFERENT APPROACHES TO ACHIEVING COMPETITION WEIGHT. THEREFORE, DEVELOPMENT AND IMPLEMENTATION OF RELIABLE AND ACCURATE HYDRATION ASSESSMENT TOOLS ARE WARRANTED. THE OBJECTIVE OF THIS ARTICLE IS TO REVIEW CURRENT RESEARCH FINDINGS OF MEASUREMENT CHARACTERISTICS CURRENTLY DEPLOYED IN COMBAT SPORTS RESEARCH.

Published: July 2016

ABSTRACT
RESERVE (PART-TIME) ARMY PERSONNEL TYPICALLY PERFORM OCCUPATIONAL AND OPERATIONAL TASKS AKIN TO THOSE OF THEIR ACTIVE-DUTY COUNTERPARTS BUT MAY HAVE LOWER FITNESS BECAUSE OF LESS PHYSICAL TRAINING. AS SUCH, RESERVE MILITARY PERSONNEL MAY BE AT A GREATER RISK OF INJURY AND HAVE PHYSICAL PERFORMANCE DEFICITS. TO IMPROVE FITNESS AND PERFORMANCE, TRAINING GUIDELINES SUGGEST 3 D/WK AEROBIC TRAINING AND 2 D/WK OF STRENGTH TRAINING, ALTHOUGH SOME DAYS MAY INCLUDE BOTH. AMONG RESERVE MILITARY PERSONNEL AWAY FROM THEIR UNITS, BOTH GENERAL AND OCCUPATIONALLY ORIENTED TRAINING COULD BE TRACKED USING COMPUTER APPLICATIONS AND/OR BY EVENING TRAINING IN GROUPS, WHICH MAY IMPROVE COMPLIANCE AND MOTIVATION.

Investigating Barriers in HIV-Testing Oncology Patients: The IBITOP Study, Phase I
Authors: Merz Laurent , Zimmermann Stefan , Peters Solange , Cavassini Matthias , Darling Katharine E.A. 
Published: July 2016

Abstract

Background.
Although the prevalence of non-AIDS-defining cancers (non-ADCs) among people living with HIV is rising, we observed HIV testing rates below 5% at our oncology center, against a regional HIV prevalence of 0.2%–0.4%. We performed the Investigating Barriers in HIV-Testing Oncology Patients (IBITOP) study among oncology physicians and patients.

Methods.
Between July 1 and October 31, 2013, patients of unknown HIV status newly diagnosed with solid-organ non-ADCs referred to Lausanne University Hospital Oncology Service, Switzerland, were offered free HIV testing as part of their oncology work-up. The primary endpoints were (a) physician willingness to offer and patient acceptance of HIV testing and (b) physicians’ reasons for not offering testing.

Results.
Of 239 patients of unknown HIV status with a new non-ADC diagnosis, 43 (18%) were offered HIV testing, of whom 4 declined (acceptance rate: 39 of 43; 91%). Except for 21 patients tested prior to oncology consultation, 175 patients (of 239; 73%) were not offered testing. Testing rate declined among patients who were &gt;70 years old (12% versus 30%; p = .04); no non-European patients were tested. Physicians gave reasons for not testing in 16% of cases, the main reason being patient follow-up elsewhere (10 patients; 5.7%). HIV testing during the IBITOP study increased the HIV testing rate to 18%.

Conclusion.
Although the IBITOP study increased HIV testing rates, most patients were not tested. Testing was low or nonexistent among individuals at risk of late HIV presentation (older patients and migrants). Barriers to testing appear to be physician-led, because patient acceptance of testing offered was very high (91%). In November 2013, the Swiss HIV testing recommendations were updated to propose testing in cancer patients. Phase II of the IBITOP study is examining the effect of these recommendations on HIV testing rates and focusing on physician-led testing barriers.

Published: July 2016

A diagnostic system is one of the key components securing the safety of operation of a turbojet engine. There are many different engineering approaches how to design engine diagnostic systems applied in real-world conditions. We propose a novel approach for a diagnostic system design to be applied on the object of a small turbojet engine using thermal diagnostics combined with a more traditional model based approach. The combination of these two approaches together with application of methods from the area of computational intelligence create a hybrid diagnostic system, which can be integrated with a control system of the engine. The article also deals with experimental validation of the designed diagnostic system on the object of a small turbojet engine iSTC-21v in laboratory conditions.
The health and welfare of dogs belonging to homeless people
Authors: Williams David Leonard , Hogg Sarah 
Published: July 2016

A significant number of homeless people own dogs, with these animals contributing to the well-being of their owners by providing emotional support and in many cases, a reason for living as well as acting as what might be termed a social catalyst improving bonds between their owners. Yet many consider that homeless people should not be allowed, let alone encouraged to keep a dog. They consider that living with a homeless people must have a negative impact on the dog’s health and welfare compared to that of a dog owned by people with a home. Here we sought to determine the health and welfare of dogs owned by homeless people, comparing 50 dogs owned by homeless people with 50 owned by people living in a home. In contradistinction to the negative view noted above, we found that dogs owned by homeless people were healthy animals, less likely to be obese, had fewer behaviour issues such as aggression to strangers and separation anxiety when compared to dogs owned by people living in a conventional home. We suggest that these findings should be taken into account when deciding whether a homeless person with a dog should be allowed into a hostel, and indeed the general attitude of the public to homeless people living with a dog by their side on the street
Transient Coupled Borehole/Formation Fluid-Flow Model for Interpretation of Oil/Water Production Logs
Authors: Frooqnia Amir , Torres-Verdín Carlos , Sepehrnoori Kamy , Abdhollah-Pour Rohollah 
Published: July 2016

Summary
Interpretation of two-phase production logs (PLs) traditionally constructs borehole fluid-flow models decoupled from the physics of reservoir rocks. However, quantifying formation dynamic petrophysical properties from PLs requires simultaneous modeling of both borehole and formation fluid-flow phenomena. This paper develops a novel transient borehole/formation fluid-flow model that allows quantification of the effect of formation petrophysical properties on measurements acquired with production-logging tools (PLTs).
We invoke a 1D, isothermal, two-fluid formulation to simulate borehole fluid-phase velocity, pressure, volume fraction, and density in oil/water-flow systems. The developed borehole fluid-flow model implements oil-dominant and water-dominant bubbly flow regimes with the inversion point taking place approximately when the oil volume fraction is equal to 0.5. Droplet diameter is dynamically modified to simulate interfacial drag effects, and to effectively account for variations of slip velocity in the borehole. Subsequently, a new successive iterative method interfaces the borehole and formation fluid-flow models by introducing appropriate source terms into the borehole fluid-phase mass-conservation equations.
The novel iterative coupling method integrated with the developed borehole fluid-flow model allows dynamic modification of reservoir boundary conditions to accurately simulate transient behavior of borehole crossflow taking place across differentially depleted rock formations. In the case of rapid variations of near-borehole properties, frequent borehole/formation communication inevitably increases the computational time required for fluid-flow simulation. Despite this limitation, in a two-layer reservoir model penetrated by a vertical borehole, the coupling method accurately quantifies a 14% increase of volume-averaged oil-phase relative permeability of the low-pressure layer caused by through-the-borehole cross-communication of differentially depleted layers. Sensitivity analyses indicate that the alteration of near-borehole petrophysical properties primarily depends on formation average pressure, fluid-phase density contrast, and borehole-deviation angle. A practical application of the new coupled fluid-flow model is numerical simulation of borehole production measurements to estimate formation average pressure from two-phase selective-inflow-performance (SIP) analysis. This study suggests that incorporating static (shut-in) PL passes into the SIP analysis could result in misleading estimation of formation average pressure.
An Example of the Success of Legal and Institutional Reform in Romania
Authors: Sora Florina , Eftimie Adriana 
Published: July 2016

Abstract
The National Agency for Mineral Resources (NAMR) was eastablished in 1993 as the regulatory authority to administer the mineral resources of Romania. It is the competent authority under the new Petroleum Law, and its responsabilities include granting concessions based on a new concession agreement in line with the international industry practice, monitoring and controlling the observance of the provisions of the concession agreement, and issuing regulations for the petroleum sector. NAMR benefitted from various programs supported by the World Bank aimed at enhancing its capabilities. Of relevant importance are the "Petroleum Exploration Promotion Program" aimed at attracting private investment by foreign companies, and the "Development of Petroleum Industry Specific Environmental Management Program" financed from a Canadian Grant. The former contributed, through the transfer of know-how to NAMR's personnel, to their successful organizing of two licensing rounds, whereas the implementation of the latter lead to the establishment of environmental management units and preparation of environmental regulations related to the petroleum sector. Since its establishment NAMR has demonstrated its commitment towards implementing the legal reforms related to the Romanian Petroleum Sector and has proved to be a modern and viable institution in an emerging free market economy.

Abstract
Petroleum Development Oman (PDO) employs male workers in its onshore oil industry on a 62 days on and 29 days off schedule.
A cross-sectional study based on three types of questionnaires was conducted on a sample population of workers to investigate any adverse effects on mental health and mood.
Though no unequivocal evidence of ill health was established, there was statistical indication that presence of children and working indoors are associated with an increase in Stress levels and a decrease in Arousal.
Further longitudinal studies on larger population samples are recommended.
Safety Performance for the Global E&P Industry

Published: July 2016

Abstract
A key component of effective safety management is the recording and analysis of safety performance measures. The OGP has the most comprehensive database in the upstream E&P industry, and prepares an annual report, analysing the current year's performance for both companies and contractors, in the context of global industry trends. The report not only enables companies to benchmark their performance against industry as a whole, but allows comparison of safety performance between different functions and localities within a company. 1998 data1 showed a continuing improvement trend in Lost Time Injury Frequency, but a worsening Fatal Accident Rate, largely influenced by an air crash in South America.
