Abstract: We introduce an innovative method for the investigation of human gait, which is based on the visualisation of the vertical component of the movement of the centre of mass during walking or running, in the space of the coordinates position, velocity, and acceleration of the centre of mass. Collected data has been numerically approximated by the best fitting curve for a non-linear model. The resulting equation for the best fitting plane or curve in this space is a differential equation of second order. The model that we suggest is a Duffing equation with coefficients that depend on the height of a walker or runner and on the angular frequency of the oscillation. Statistics about the distribution of the Duffing stiffness depending on the speed is presented. 1 We study the human gait modelled by the movement of the centre of mass of the test person. This is an ex le of a biological process which can be considered as a periodical dynamic system. Roughly, this movement behaves in a similar way to a vibrating mass suspended on a spring, but it is more complex. The vertical component of the movement during walking or running can be visualised as an oscillogram: a graph of the position as a function of time. We suggest a visualisation of the data in 3D space, where the coordinates describe position, velocity, and acceleration. Our new visualisation method allows us to model the movement of a person’s centre of mass by a nonlinear differential equation. The resulting curve for an ideal spring-mass movement, without viscosity or external force, is an ellipse in the suggested 3D space. The shape of the data curve shows at which position an additional force was applied, or the movement slowed down. Some deviations are common for all test persons and others are different. In the future we plan to investigate the reasons for these deviations, such as different running techniques or the presence of injuries.

Abstract: An integrated experimental and thermodynamic modeling study has been used to characterize phase equilibria in the Pb-Fe-O-S-Si system. The experimental approach developed for investigation of this system, which involves the use of high-temperature equilibration, quenching, and electron probe X-ray microanalysis, has enabled to overcome difficulties associated with high corrosive tendency of the condensed phases and high vaporization rates of Pb species specific to this system. The study shows that systematic, accurate direct experimental measurements of the Pb, Fe, Si, and S concentrations in the coexisting phases in this system are now possible. The results obtained for the slag-matte-metal-tridymite phase equilibria at 1100 °C and 1200 °C appear to be the first systematic quantitative experimental data on phase compositions in equilibrium in the Pb-Fe-O-S-Si system. First systematic experimental measurements have also been undertaken for the gas-slag-matte-tridymite equilibria at p (SO 2 ) = 0.6 atm at 1200 °C. Thermodynamic calculations have been performed using the FactSage thermodynamic package. The experimental data have been used, along with other relevant measurements, to develop a self-consistent thermodynamic database that can be used for optimization of industrial processes.

Abstract: Present society challenges, including metal scarcity, recycling, and environmental restrictions, resulted in the increased complexity and variability of metallurgical feed streams. Metallurgical processes involving complex lead and copper-containing slag and matte phases are now commonly used in response. Optimization of existing and development of new metallurgical processes require fundamental information on slag–matte phase equilibrium. Development of the experimental methodology for the characterization of slag–matte phase equilibrium is presented in the paper. Following a detailed analysis of the potential reaction pathways, experimental techniques have been developed that enable accurate measurement of slag–matte phase equilibrium in the Pb-Fe-O-S-Si system. The application of the techniques has been demonstrated for two important sets of conditions: (i) Condensed phase equilibrium for the slag–matte–metal–tridymite subsystem and (ii) Gas–slag–matte–tridymite equilibrium at fixed oxygen and sulfur partial pressures. The experimental methodology involves high-temperature equilibration of synthetic s les, fast quenching, and microanalysis of the compositions of phases using electron probe X-ray microanalysis (EPMA). The experimental results are not affected by the changes in the bulk composition of s les during equilibration this helps to overcome the significant barriers previously encountered in undertaking accurate measurement and characterization of these systems.

Abstract: Quantifying the training and competition loads of players in contact team sports can be performed in a variety of ways, including kinematic, perceptual, heart rate or biochemical monitoring methods. Whilst these approaches provide data relevant for team sports practitioners and athletes, their application to a contact team sport setting can sometimes be challenging or illogical. Furthermore, these methods can generate large fragmented datasets, do not provide a single global measure of training load and cannot adequately quantify all key elements of performance in contact team sports. A previous attempt to address these limitations via the estimation of metabolic energy demand (global energy measurement) has been criticised for its inability to fully quantify the energetic costs of team sports, particularly during collisions. This is despite the seemingly unintentional misapplication of the model's principles to settings outside of its intended use. There are other hindrances to the application of such models, which are discussed herein, such as the data-handling procedures of Global Position System manufacturers and the unrealistic expectations of end users. Nevertheless, we propose an alternative energetic approach, based on Global Positioning System-derived data, to improve the assessment of mechanical load in contact team sports. We present a framework for the estimation of mechanical work performed during locomotor and contact events with the capacity to globally quantify the work done during training and matches.

Abstract: We study an interacting particle system on the simple cubic lattice satisfying the nearest neighbor exclusion (NNE) which forbids any two nearest sites to be simultaneously occupied. Under the constraint, we develop an edge-to-site reduction of the Bethe-Peierls entropy approximation of the cluster variation method. The resulting NNE-corrected Bragg-Williams approximation is applied to statistical mechanical modeling of a liquid silicate formed by silica and a univalent network modifier, for which we derive the molar Gibbs energy of mixing and enthalpy of mixing and compare the predictions with available thermodynamic data.

Abstract: Magnesium oxide-based refractory materials are used industrially to contain the chemically aggressive slags present in lead smelting systems. In the present study an integrated experimental and thermodynamic modeling approach was taken to provide fundamental information on the chemical reactions taking place in these systems. New experimental phase equilibria and liquidus data were obtained for the PbO–MgO–SiO 2 system in air in the temperature range 750 °C to 1740 °C. In the MgO–SiO 2 binary, new experimental results were obtained at 1550 °C to 1740 °C and compared to the available thermodynamic data in the literature. The experiments were carried out using the high-temperature equilibration of oxide powder mixtures followed by rapid quenching of the s les. Electron probe X-ray microanalysis (EPMA) was used to determine the compositions of the solid and liquid phases present at equilibrium conditions. Phase equilibria and liquidus isotherms in the cristobalite and tridymite (SiO 2 ), pyroxene (protoenstatite MgSiO 3 ), olivine (forsterite Mg 2 SiO 4 ), barysilite (Pb 8 MgSi 6 O 21 ), massicot (PbO) and periclase (MgO) primary phase fields were measured, and the extent of the high-silica two-liquid immiscibility gap in equilibrium with cristobalite was determined. The experimental results were used to optimize the parameters in a thermodynamic database that was subsequently used to describe this multi-component, multi-phase system and predict the liquidus for the PbO–MgO–SiO 2 system. The new data were used to characterize the chemical interactions of magnesia-based refractory with PbO–MgO–SiO 2 slags.

Abstract: The combined effects of Al 2 O 3 , CaO and MgO slagging components on phase equilibria and thermodynamics in the basic Cu–Fe–O–S–Si system have been evaluated at 1473 K (1200 ºC) and p (SO 2 ) = 0.25 atm for a range of oxygen partial pressures and matte compositions. The experimental technique included high-temperature equilibration of the s les on a spinel substrate under controlled gas atmosphere (CO/CO 2 /SO 2 /Ar), followed by rapid quenching and subsequent measurement of the equilibrium phase compositions using Electron Probe X-ray Microanalysis (EPMA). The experimental data have been compared with the results of thermodynamic calculations undertaken using FactSage software and an internal thermodynamic database. Both the experimental results and the calculations results revealed that the presence of Al 2 O 3 , CaO and MgO reduced both the sulphur and copper concentrations in the slag phase for a given set of process conditions. The data have been used for further optimisation of the parameters of the thermodynamic database describing multicomponent metallurgical systems. The resulting thermodynamic database is capable of predicting, with high accuracy, the phase equilibria and the distribution of all elements between the phases in the Cu–Fe–O–S–Si–(Al, Ca, Mg) system.

Abstract: Cummins, CJ, Gray, AJ, Shorter, KA, Halaki, M, and Orr, R. Energetic demands of interchange and full-match rugby league players. J Strength Cond Res 32(12): 3456–3464, 2018—The purpose of this study was to describe and compare the metabolic demands of rugby league for interchange and full-match players in relation to positional groups. Eighteen elite rugby league players were recruited. A time-motion model was used to estimate the energy expenditure and metabolic demands of rugby league match-play using Global Positioning System (GPS) technology. This approach uses players' GPS velocity-time curves to examine running velocity. Players were categorized into positional groups (outside backs, adjustables, wide-running, and hit-up forwards) and then further categorized into full-match or interchange players. Compared with their full-match counterparts, interchange wide-running forwards expended greater energy (43.1 ± 6.1 vs. 28.6 ± 7.5 kJ·kg −1 , p ≤ 0.001, effect size [ES] = −2.38) and produced a higher anaerobic index ( p = 0.016, ES = 0.56) and mean power (7.4%, p = 0.003, ES = 0.66) per match. Full-match adjustables expended 94.8% more energy ( p ≤ 0.001, ES = −2.3) and performed more moderate accelerations (10.1%, p = 0.014, ES = −0.57) and decelerations (7.6%, p = 0.017, ES = −0.8), than their interchange counterparts. Outside backs did not interchange and hit-up forwards rarely ( n = 2) played an entire match. Differing metabolic demands were identified for interchange and full-match players across positional groups, suggesting position-specific conditioning drills are required to model the energetic demands of match-play.

Abstract: Laboratory experimental study was undertaken to characterise the four-phase slag/matte/metal/tridymite equilibria of the Cu-Fe-O-S-Si system at 1473 K [1200°C], 1523 K [1250° C] and 1573 [1300°C] in a "closed" system without interaction with gas phase. The research methodology involved high temperature equilibration, ultra-fast quenching of the equilibrated s les followed by quantitative measurement of the equilibrated phases by electron probe X-ray microanalysis. Attainment of chemical equilibrium was carefully checked by the 4-points test approach. The results obtained in the present study provide reliable fundamental experimental information, which is crucial for the development and optimisation of the multicomponent thermodynamic database for copper-containing systems.

Abstract: The liquidus of the ternary system ZnO–“FeO 1.5 ”–SiO 2 in air has been experimentally investigated in the tridymite and cristobalite, spinel, and zincite primary phase fields in the temperature range 1623–1923 K (1350–1650°C). Slags containing up to 65 mol.% “FeO 1.5 ” have been studied for the first time. The slag–spinel–zincite eutectic in the binary ZnO–“FeO 1.5 ” system in air has been estimated by extrapolation of the low-SiO 2 part of the ternary system to x (SiO 2 ) = 0. High-temperature equilibration on primary phase (silica) or inert metal (platinum) substrates, followed by quenching and direct measurement of Zn, Fe and Si concentrations in the equilibrium phases with electron probe X-ray microanalysis has been used to accurately characterize the system in equilibrium with air. The discrepancies of the previous experimental work in this system have been resolved. The obtained data have been used to reoptimise the existing thermodynamic model.

Abstract: The purpose of this study was to apply a time-motion model to estimate and describe the energy expenditure and metabolic power demands of playing positions in elite rugby league match-play, utilizing Global Positioning System (GPS) devices. 18 elite rugby league players participated in this study. Players' positional groups included: outside backs (n=59 files, n=4 players), adjustables (n=74 files, n=4 players), wide-running (n=104 files, n=7 players) and hit-up forwards (n=36 files, n=3 players). Outside backs expended the greatest total energy (40.1±5.0 kJ·kg(-1)) per match, equivalent to 8.1%, 26.6% and 61.9% greater energy than adjustables, wide-running and hit-up forwards, respectively. Adjustables attained an anaerobic index 7.3% higher than wide-running forwards, 19.7% higher than hit-up forwards (p=0.001) and 43.2% higher than outside backs (p<0.001). Wide-running forwards achieved an anaerobic index (0.34±0.04) 11% and 32.8% higher than hit-up forwards (p=0.001) and outside backs (p<0.001), respectively. Mean power of adjustables (10.0±0.9 W·kg(-1)) was significantly higher than all other groups (outside backs: 28.8%, 7.8±1.0 hit-up: 12.4%, 8.9±0.6 and wide-running: 8.7%, 9.2±0.7 forwards) (p<0.001). Energetics indices indicated differing metabolic demands for all positional groups, suggesting position-specific conditioning drills are required to replicate the energetic demands of match-play.

Abstract: To investigate temporal variation in running intensity across and within halves and evaluate the agreement between match-analysis indices used to identify fluctuations in running intensity in rugby sevens. Data from a 15-Hz global positioning system (GPS) were collected from 12 elite rugby sevens players during the IRB World Sevens Series (N = 21 full games). Kinematic (eg, relative distance [RD]) and energetic (eg, metabolic power [MP]) match-analysis indices were determined from velocity–time curves and used to investigate between-halves variations. Mean MP and RD were used to identify peak 2-minute periods of play. Adjacent 2-minute periods (prepeak and postpeak) were compared with peak periods to identify changes in intensity. MP and RD were expressed relative to maximal oxygen uptake (V̇O 2max ) and speed at V̇O 2max , respectively, and compared in their ability to describe the intensity of peak periods and their temporal occurrence. Small to moderate reductions were present for kinematic (RD 8.9%) and energetic (MP 6%) indices between halves. Peak periods (RD = 130 m/min, MP =13 W/kg) were higher ( P .001) than the match average (RD = 94 m/min, MP = 9.5 W/kg) and the prepeak and postpeak periods ( P .001). RD underestimated the intensity of peak periods compared with MP (bias 16%, limits of agreement [LoA] ± 6%). Peak periods identified by RD and MP were temporally dissociated (bias 21 s, LoA ± 212 s). The findings suggest that running intensity varies between and within halves however, the index used will influence both the magnitude and the temporal identification of peak periods.

Abstract: Hagstrom, AD, Shorter, KA, and Marshall, PWM. Changes in unilateral upper limb muscular strength and Electroymographic activity after a 16-week strength training intervention in survivors of breast cancer. J Strength Cond Res 33(1): 225–233, 2019—Upper limb strength deficits are frequently observed following breast cancer (BC) and its treatments. It is currently unknown whether these unilateral deficits can be corrected by a standard bilateral strength training intervention. Twenty-three survivors of BC were included in this analysis. Fourteen performed a 16-week resistance training (RT) intervention, 9 were assigned to a usual care waitlist control group. Electromyographic analysis of the pectoralis major and triceps brachii were monitored during 3 maximal isometric contractions and a fatiguing endurance task. Muscular strength was significantly different between limbs at the start of the intervention ( p = 0.02). Electromyographic litude and median frequency did not differ between limbs at the start of the intervention. Muscular strength was significantly different between limbs in the RT group at the end of the intervention ( p = 0.01). Electromyographic litude did not differ between limbs or groups at the end of the intervention. Bilateral strength training did not correct the unilateral strength deficit observed in this group of survivors of breast cancer. Periods of unilateral strength training should be implemented into periodized RT programs in this cohort.

Abstract: Due to the increasing complexity of materials processed in primary and secondary lead smelting, better control of impurity elements is required. In the present study, distributions of Cu, As, Sb and Sn between PbO–FeO–Fe 2 O 3 –SiO 2 slag and Pb metal are characterized experimentally and analyzed using thermodynamic calculations. Experimental methodology involved closed-system equilibration of s le mixtures at high temperature followed by rapid quenching. The compositions of phases were measured using electron probe X-ray microanalysis and laser ablation inductively coupled plasma mass spectrometry. Thermodynamic calculations were performed using the FactSage software coupled with an internal thermodynamic database. Experimentally obtained distribution coefficients wt.% in slag/wt.% in metal at 1 200 °C (1 473 K) follow the sequence Sn Cu As ≈ Sb at P (O 2 ) 10 −9.5 atm and Sn As ≈ Sb Cu at P (O 2 ) 10 −8.5 atm. Model predictions are in good agreement with the experiment.

Abstract: Physiological or performance tests are routinely utilised to assess athletes' recovery. At present, the ideal tool to assess recovery remains unknown. Therefore, the aim of this systematic review was to examine the change in creatine kinase (CK) and neuromuscular function as measured via a countermovement jump (CMJ) following a match in the contact codes of football. A comprehensive search of databases was undertaken with RevMan (V 5.3) used for statistical analysis. Our results demonstrated that CK pre- versus post-match (standardised mean difference (SMD) = 0.90, 95% CI = 0.50 to 1.31, p < .0001), CK pre- versus 24 h post-match (SMD = 1.50, 95% CI = 1.12 to 1.88, p < .00001), and CK pre- versus 48 h post-match all increased significantly (SMD = 0.90, 95% CI = 0.50 to 1.31, p < .0001), while CMJ peak power (PP) pre- versus post-match (SMD = -0.59, 95% CI = -1.12 to -0.06, p = .03), and pre- versus 24 h post-match (SMD = -0.80, 95% CI = -1.31 to -0.28, p = .002) decreased significantly. There was a significant relationship between the change in CK and the change in CMJ PP from immediately pre to immediately post (r = -0.924, p = .025), and between CMJ immediately following a match and 24 h CK change (r = -0.983, p = .017). In conclusion, CK levels increase and performance in the CMJ decreases following a match of a contact code of football. The identification of this relationship may allow coaching staff to implement a standalone measure of recovery.

Abstract: Empty nose syndrome (ENS) is a debilitating disorder thought to arise as a postsurgical phenomenon from excessive loss of nasal tissues. Affected patients often report a profound impact on all aspects of life, but the extent of this burden has not been quantified. We sought to determine the association of ENS with mental health and functional impairments. A cross-sectional study was performed of in iduals with ENS recruited from online ENS forums. ENS status was validated based on a positive 6-item Empty Nose Syndrome Questionnaire (ENS6Q) score and sinus computed tomography imaging or supporting medical documentation. Subjects completed the ENS6Q, the 9-item Patient Health Questionnaire (PHQ-9) for depression, the 7-item Generalized Anxiety Disorder questionnaire (GAD-7), the Epworth Sleepiness Scale for daytime somnolence (ESS), the Work Productivity and Impairment questionnaire (WPAI), and the 5-dimension EuroQol General Health State Survey (EQ-5D-5L). Pearson correlation analysis was performed with α = 0.05 to determine significance. Fifty-three ENS in iduals were included in the study. Overall, participants reported symptoms consistent with moderate anxiety (μ = 12.7 standard deviation [SD], 5.9) and moderately severe depression warranting treatment (μ = 17.9 SD, 6.8). Participants also noted a 62% reduction in productivity at work (n = 24) and 65% in all other activities (n = 53). ENS6Q symptom severity was correlated with more severe depression (p < 0.001), anxiety (p < 0.001), overall pain/discomfort (p = 0.002), and impairment in activities of daily living (p = 0.003). ENS in iduals carry a clinically significant psychological burden and experience marked difficulties with many activities of daily living. A multimodal approach to address the tissue loss with surgery and cognitive-behavioral therapy for the psychological burden may provide the most optimal outcome.

Abstract: The experimental study of the phase equilibria between calcium ferrite slag, metallic copper, spinel and/or dicalcium ferrite in the Cu 2 O-FeO x -CaO system has been carried out. Effects of temperature, oxygen partial pressure and Fe/CaO ratio on phase assemblages and compositions have been estimated. The advanced experimental technique including high-temperature equilibration on primary phase substrates, rapid quenching of the s les and quantitative measurements of equilibrated phase compositions using electron probe X-ray microanalysis has been applied. Spinel and dicalcium ferrite substrates have been specially designed to study phase equilibria at certain primary phase fields. Obtained experimental results have been compared with thermodynamic assessment of the Cu 2 O-FeO x -CaO system and available literature data.
