The measurement of methane emissions from landfills is important to the understanding of landfills' contribution to greenhouse gas emissions. The Tracer Dispersion Method (TDM) is becoming widely accepted as a technique, which allows landfill emissions to be quantified accurately provided that measurements are taken where the plumes of a released tracer-gas and landfill-gas are well-mixed. However, the distance at which full mixing of the gases occurs is generally unknown prior to any experimental campaign...

Stent thrombosis is a major complication of coronary stent and scaffold intervention. While often unanticipated and lethal, its incidence is low making mechanistic examination difficult through clinical investigation alone. Thus, throughout the technological advancement of these devices, experimental models have been indispensable in furthering our understanding of device safety and efficacy. As we refine model systems to gain deeper insight into adverse events, it is equally important that we continue to refine our measurement methods...

Metabolomic profiling of nine trained ultramarathon runners completing an 80.5 km self-paced treadmill-based time trial was carried out. Plasma samples were obtained from venous whole blood, collected at rest and on completion of the distance (post-80.5 km). The samples were analyzed by using high-resolution mass spectrometry in combination with both hydrophilic interaction (HILIC) and reversed phase (RP) chromatography. The extracted putatively identified features were modeled using Simca P 14.1 software (Umetrics, Umea, Sweden)...

Almost half of the world's total population reside in rural and remote areas and a large number of these people remain deprived of most basic facilities like healthcare and education. It is deemed impossible for government with scarce resources in developing countries to open and run a health facility in every remote community using conventional means. One increasingly popular unconventional mean is the use of existing technology to improve exchange of medical information for the purpose of improving health of underprivileged communities...

Bone protection and metabolism are directly linked to estrogen levels, but exercise is also considered to have bone protective effects. Reduced estrogen levels lead to a variety of disorders, for example, bone loss and reduced movement drive. The objective of this study was to investigate the effects of estrogen on individual voluntary exercise motivation and bone protection. We investigated sham operated, ovariectomized, and ovariectomized with estrogen supplemented Wistar rats (20 weeks old) either with or without access to exercise wheels...

The extent to which N-Methyl-D-aspartate (NMDA) receptors facilitate the motivation to voluntarily wheel-run in rodents has yet to be determined. In so, we utilized female Wistar rats selectively bred to voluntarily run high (HVR) and low (LVR) nightly distances in order to examine if endogenous differences in nucleus accumbens (NAc) NMDA receptor expression and function underlies the propensity for high or low motivation to voluntarily wheel-run. 12-14 week old HVR and LVR females were used to examine: 1.) NAc mRNA and protein expression of NMDA subunits NR1, NR2A and NR2B; 2...

This study aimed to clarify the influence of vertical impulse on the magnitude of step length (SL) and frequency (SF) and their ratio during the entire acceleration phase of maximal sprinting. Thirty-nine male soccer players performed 60-m sprints, during which step-to-step ground reaction forces were recorded over a 50-m distance. The mean values of spatiotemporal variables and vertical and anteroposterior impulses for each set of four steps during the acceleration phase until the 28th step were computed to examine relationships among variables in seven sections...

There is a growing consensus that chronic kidney disease (CKD) patients should engage in regular exercise, but there is a lack of formal guidelines. In this report, we determined whether combined aerobic and resistance exercise would elicit superior physiological gains, in particular muscular strength, compared to aerobic training alone in non-dialysis CKD. Non-dialysis CKD patients stage 3b-5 were randomly allocated to aerobic exercise (AE, n=21; 9 males; median age 63years [IQR, 58-71]; median eGFR 24[IQR, 20-30] mL/min/1...

INTRODUCTION: Severe lower-limb trauma is a major event in a patient's life, and treatment is a challenge that has not been sufficiently studied. The main objective of the present study was to assess the difference in disability between amputees and patients who kept their leg after severe open lower-limb fracture. HYPOTHESIS: The study hypothesis was that amputation allows better functional recovery and quality of life, in the same time-frame. MATERIALS AND METHODS: All male and female patients aged over 18 years admitted to one of the trauma centers of Marseille (France) for major lower-limb trauma with Gustilo IIIb or IIIc fracture were included...

We compared ten published equations for calculating energy expenditure from oxygen consumption and carbon dioxide production using data for 10 high-caliber male distance runners over a wide range of running velocities. We found up to a 5.2% difference in calculated metabolic rate between two widely used equations. We urge our fellow researchers abandon out-of-date equations with published acknowledgments of errors or inappropriate biochemical/physical assumptions.

BACKGROUND: The aims of this study were to analyze the relationships between the medial orbitofrontal artery (MOFA) and the anterior skull base (ASB) including anatomical endonasal landmarks using computed tomography angiography (CTA). METHODS: We studied 52 CTAs using OsiriX software. All CTAs were placed in the same anatomical position. MOFA was identified in the sagittal and coronal plane and its correlation with ASB was analyzed. The distance between the MOFA and landmarks for endonasal surgery were obtained, determining the high risk areas for its injury...

Objectives: While the health benefits of running are legitimately advocated, participation in running can also lead to health problems. There is a high range of reported prevalence rates especially of running-related overuse injuries in high-level athletes and during competition. Little consensus exists for acute injuries and illnesses especially in recreational runners. Therefore, the aim of this study was to record the prevalence of health problems in recreational long-distance runners preparing for an event...

The round-robin-differential-phase-shift (RRDPS) quantum key distribution (QKD) protocol has attracted intensive study due to its distinct security characteristics; e.g., information leakage is bounded without learning the error rate of key bits. Nevertheless, its practicality and performance are still not satisfactory. Here, by observing the phase randomization of the encoding states and its connection with eavesdropper's attack, we develop an improved bound on information leakage. Interestingly, our theory is especially useful for implementations with short trains of pulses, and running without monitoring signal disturbance is still available...

Though positive effects of exercise on mood and well being are well recognised, the central regulatory mechanisms are still not fully understood. The present study was aimed to testing the hypothesis that voluntary wheel running activates the gene expression of glutamate transporters in the brain cortex of rats. The animals were assigned to the control and voluntary wheel running groups. Voluntary wheel running rats had free access to a stainless steel activity wheel for 3 weeks. The daily running distance gradually increased to 6...

The shape diameter function (SDF) is a scalar function defined on a closed manifold surface, measuring the neighborhood diameter of the object at each point. Due to its pose oblivious property, SDF is widely used in shape analysis, segmentation and retrieval. However, computing SDF is computationally expensive since one has to place an inverted cone at each point and then average the penetration distances for a number of rays inside the cone. Furthermore, the shape diameters are highly sensitive to local geometric features as well as the normal vectors, hence diminishing their applications to real-world meshes which often contain rich geometric details and/or various types of defects, such as noise and gaps...
