Abstract
(Poly)phosphonic acids constitute an exciting family of phosphorus compounds. One of the attractive attributes of these molecules is the rich chemistry of the phosphonate moiety, and, in particular, its high affinity for metal ions and mineral surfaces. Whether the phosphonate group belongs to a “small” molecule or to a polymeric matrix, phosphonate-containing compounds have found a phalanx of real-life applications. Herein, we address a special category of phosphorus compounds called bisphosphonates (BPs, a.k.a. “-dronates”) and also phosphonate containing polymers. The success of BPs in mitigating osteoporosis notwithstanding, these “-dronate” drugs present a number of challenges. Nevertheless, the main drawback of BPs is their limited oral bioavailability. It is, therefore, imperative to design and fabricate “smart” systems that allow controlled delivery of the active BP agent. Here, easy-to-prepare drug delivery systems are presented based on silica gels. These have been synthesized, characterized, and studied as hosts in the control release of several BP drugs. They exhibit variable release rates and final % release, depending on the nature of bisphosphonate (side-chain length, hydro-philicity/-phobicity, water-solubility), cations present, pH and temperature. These gels are robust, injectable, re-loadable and re-usable. Furthermore, alternative drug delivery systems are presented that are based on metal-organic frameworks (MOFs). In these biologically acceptable inorganic metal ions have been incorporated, together with BPs as the organic portion. These materials have been synthesized, characterized, and studied for the self-sacrificial release (by pH-driven dissolution) of the BP active ingredient. Several such materials were prepared with a variety of bisphosphonate drugs. They exhibit variable release rates and final % release, depending on the actual structure of the metal-bisphosphonate material. Lastly, we will present the use of phosphonate-grafted polymers as scale inhibitors for water treatment applications.
The First Medea and the Other Heracles
Authors: Meccariello Chiara 
Published: December 2018

Abstract
This paper focuses on the presumed existence of two versions of Medea and Heracles in the Euripidean corpus that circulated in antiquity. After a brief review of the main papyrological evidence, namely P.Oxy. LXXVI 5093 for the Medea and P.Hibeh II 179 for the Heracles, I discuss the implications of adding another Medea and another Heracles to the Euripidean corpus in the light of the extant ancient testimonies on the number of works in Euripides’ oeuvre. Moreover, I examine the clues provided by the headings of the hypotheses of the extant Medea and the extant Heracles as preserved in P.IFAO inv. PSP 248 and P.Oxy. LXXXI 5284. On these grounds, I argue that the supposed evidence for the existence of two distinct Medea and two distinct Heracles plays should not be interpreted as evidence of double authorial versions.
Determination of the fundamental dimension development in building direction for laser-sintered parts
Authors: Launhardt Martin , Drummer Dietmar 
Published: December 2018

Abstract
The additive manufacturing process of the laser sintering of polymers (LS) allows the production of complex parts right from CAD data. However, the manufactured parts often show dimensional inaccuracies. In order to fundamentally determine the influencing parameters on the accuracy of LS parts, a hatching specimen, a layer-specimen and defined part geometries are manufactured and subsequently measured. These, combined with a theoretical observation of the layer wise geometry buildup, are used to determine the fundamental portions of the development of dimensions in building direction (z-direction). The results indicated a defined powder adhesion height at the top and the bottom of a melted layer, along with the dependency of melt depth and the hatch number for small structures. Depending on the nominal heights of an LS part, either an oversize or undersize was detected.

Abstract
The reaction of Ni(OH)2 and methanetrisulfonic acid trihydrate CH(SO3H)3·3H2O (H3MTA·3H2O) in N-methyl-pyrrolidone (NMP) leads to the trinuclear complex {Ni3[MTA]2(NMP)8} (triclinic, P1̅, Z=1, a=946.25(3), b=1073.24(3), c=1518.27(4) pm, α=72.193(2), β=87.398(2), γ=89.389(2)°, V=1466.49(7)×106 pm3). The structural features of the methanetrisulfonate anions are tripodal as well as chelating coordination of the Ni2+ ions. The thermal analysis has shown that the compound is first losing NMP molecules and that the solvent-free methanetrisulfonate finally decomposes yielding Ni3S2.

Abstract
The importance of the synthesis conditions on the structural and photocatalytic properties of tantalum oxide nitride was investigated by comparing two variants of phase-pure β-TaON obtained from application of two different synthesis routes, leading to one unstrained and one heavily anisotropically microstrained β-TaON as shown by XRD-based Rietveld refinement. HRTEM images reveal the origin of the strain to be lattice defects such as stacking faults. The strained β-TaON was found to be the clearly less active semiconductor in photochemical and photoelectrochemical water oxidation. The lattice defects are assumed to act as charge carrier traps hindering the photo-generated holes to be displaced to the reaction sites at the surface.

Abstract
Keller, M, Kuhn, YA, Lüthy, F, and Taube, W. How to serve faster in tennis: the influence of an altered focus of attention and augmented feedback on service speed in elite players. J Strength Cond Res 35(4): 1119–1126, 2021—Different approaches, such as providing augmented feedback (AF) or adopting an external focus of attention (EF), have been shown to directly enhance performance in recreational athletes. Furthermore, research has shown that combining AF with EF (AF + EF) results in superior performance compared to AF and EF alone. Here, we tested the influence of AF, EF, AF + EF, and an internal focus of attention (IF) on service speed in elite tennis players. High-level national tennis players (19.2 ± 3.7 years) were asked to serve flat serves to a target zone with maximum speed. With respect to service speed, a significant main effect of condition was found (p ≤ 0.001). Post hoc comparisons revealed faster serves for AF compared to control serves without instruction/feedback (p < 0.01) and compared to EF (p < 0.05), whereas no significant difference was found between EF and IF (p = 0.81). The fastest service speeds were found in the AF condition, whereas the combination of AF + EF did not further promote performance. The number of serves landed in the target zone did not differ between conditions (p = 0.17). Thus, no speed-accuracy trade-off was found, indicating that enhanced service speeds did not result in less serves landed in the target zone. Augmented feedback seems most beneficial to instantly enhance tennis serve performance. In contrast to previous studies with recreational sportsmen, EF did not differ from IF, providing further evidence that expertise level and task-relevant instructions mediate the influence of attentional focus on motor performance.

Abstract
Muniz-Pumares, D, Karsten, B, Triska, C, and Glaister, M. Methodological approaches and related challenges associated with the determination of critical power and W′. J Strength Cond Res 33(2): 584–596, 2019—The relationship between exercise intensity and time to task failure (P-T relationship) is hyperbolic, and characterized by its asymptote (critical power [CP]) and curvature constant (W′). The determination of these parameters is of interest for researchers and practitioners, but the testing protocol for CP and W′ determination has not yet been standardized. Conventionally, a series of constant work rate (CWR) tests to task failure have been used to construct the P-T relationship. However, the duration, number, and recovery between predictive CWR and the mathematical model (hyperbolic or derived linear models) are known to affect CP and W′. Moreover, repeating CWR may be deemed as a cumbersome and impractical protocol. Recently, CP and W′ have been determined in field and laboratory settings using time trials, but the validity of these methods has raised concerns. Alternatively, a 3-minute all-out test (3MT) has been suggested, as it provides a simpler method for the determination of CP and W′, whereby power output at the end of the test represents CP, and the amount of work performed above this end-test power equates to W′. However, the 3MT still requires an initial incremental test and may overestimate CP. The aim of this review is, therefore, to appraise current methods to estimate CP and W′, providing guidelines and suggestions for future research where appropriate.

Abstract
Sassone, J, Muster, M, and Barrack, MT. Prevalence and predictors of higher-risk supplement use among National Collegiate Athletic Association Division I athletes. J Strength Cond Res 33(2): 443–450, 2019—This study aimed to identify the prevalence and predictors associated with the use of higher-risk dietary supplements, defined as supplements containing herbal ingredients, caffeine, or those classified for weight loss, muscle-building, or as a preworkout supplement, among 557 National Collegiate Athletic Association Division I male and female collegiate athletes. Although 252 (45.2%) athletes reported the use of a dietary supplement on ≥2 days per week over the past year, 46 (8.3%) athletes met criteria for higher-risk supplement use. Twenty (3.6%) athletes reported the use of herbal, 1 (0.2%) caffeinated, 5 (0.9%) weight loss, 28 (5.0%) preworkout, and 1 (0.2%) muscle-building supplements. Body mass index status (BMI ≥30 kg·m−2), sport-type (sports using the phosphocreatine energy system), and college year (≥4th year) were associated with the use of preworkout, muscle-building, or herbal supplements. A multiple regression analysis identified predictors of higher-risk supplement use including the number of dietary supplements used in the past year (odds ratio [OR] = 2.1, 95% confidence interval [CI] = 1.7–2.7, p < 0.001), the reported motivation of taking dietary supplements to gain muscle and lose body fat (OR = 3.5, 95% CI = 1.1–11.7, p = 0.04), and the motivation to increase athletic endurance (OR = 3.5, 95% CI = 4.0, 95% CI = 1.6–9.9, p < 0.005). These factors may be considered as a part of a screening process to evaluate athletes with an increased risk of higher-risk supplement use and potential consequences to health or eligibility status.

Abstract
Ballmann, CG, McCullum, MJ, Rogers, RR, Marshall, MR , and Williams, TD. Effects of preferred vs. nonpreferred music on resistance exercise performance. J Strength Cond Res 35(6): 1650–1655, 2021—The purpose of this study was to examine the effects of listening to preferred vs. nonpreferred music on resistance exercise performance. Twelve resistance-trained college-aged males (age = 20.5 ± 1.24 years, height = 183.9 ± 6.8 cm, and body mass = 97.0 ± 18.2 kg) were recruited for this study. In a within-groups counterbalanced study design, subjects either listened to preferred or nonpreferred music during a bench press exercise test. Subjects completed as many repetitions as possible at 75% of their 1 repetition maximum with maximum explosive intent. Power and velocity of the barbell movement was measured for the first 3 repetitions using a linear position transducer. Motivation was measured using a visual analog scale immediately after exercise. Each exercise trial was separated by a 48-hour washout period. Results indicate that listening to preferred music increased overall bench press repetitions completed (p = 0.005; effect size [ES] = 0.84). During the first 3 repetitions, mean velocity (p = 0.001; ES = 1.6), relative mean power (p = 0.012; ES = 0.55), peak velocity (p = 0.011; ES = 0.99), and peak power (p = 0.009; ES = 0.35) were higher while listening to preferred music vs. nonpreferred music. Finally, motivation during the lift (p < 0.001; ES = 5.9) was significantly higher while listening to preferred vs. nonpreferred music. Current findings suggest that listening to preferred music by the individual results in greater performance than nonpreferred during resistance exercise. Athletes may benefit from the option to listen to their preferred music to increase motivation and resistance exercise performance.

Abstract
Ferley, DD and Vukovich, MD. Assessing the reliability of using a horizontal leg press equipped with a force plate to report on measures of positive and negative neuromuscular characteristics. J Strength Cond Res 33(2): 360–371, 2019—Individuals participating in sport or returning from a lower-extremity injury routinely perform assessments of lower-body anaerobic capacity and power to gauge fitness or readiness to return to competition. However, many commonly used assessments lack the specificity of movement and muscle contraction demonstrated in sprinting, jumping, and changing direction. Therefore, this investigation assessed the reliability of a novel lower-body power test called a Plyo Press Power Quotient (3PQ), which involves jumping on a horizontal leg press equipped with a force plate. Thirty participants completed 1 repetition maximum (1RM) strength testing for 1 and 2 legs and a countermovement vertical jump. Two trials of 1- and 2-leg jump tests were performed using 30, 40, 50, and 60% of 1RM for 20 and 30 seconds, respectively. Dependent variables were a variety of positive (concentric) and negative (eccentric) neuromuscular indices. Statistical significance was set to p ≤ 0.05. No significant differences existed between trial 1 and 2 for any measures. One-way analysis of variance between %1RM conditions revealed significant differences in peak force (right; both), average negative power (left; right), average negative work (left; right), rate of power development (both), percent positive and negative fatigue (left; right; both), and velocity of movement (left; right; both). Peak power of all 2-leg jump tests correlated highly with vertical jump (r ≥ 0.89) but was significantly different. We conclude 3PQ testing provides a reliable assessment of anaerobic capacity and power, with the added benefit of easy single-leg comparisons.

Abstract
Naugle, KE, Carey, C, Ohlman, T, Godza, M, Mikesky, A, and Naugle, KM. Improving active gaming's energy expenditure in healthy adults using structured playing instructions for the Nintendo Wii and Xbox Kinect. J Strength Cond Res 33(2): 549–558, 2019—Professionals work constantly to increase energy expenditure and improve cardiovascular outcomes. A newer form of physical activity used to improve cardiovascular outcomes and increase energy expenditure while also providing entertainment is active gaming. The purpose was to determine energy expenditure and enjoyment levels during participation in different games played with a directed set of instructions designed to enhance movement. Twenty-one adults completed 6 sessions (1 familiarization and 5 experimental) on separate days. During 4 of the experimental sessions, participants played 1 of 4 active games for two 15-minute periods. Two active games were from Xbox Kinect and 2 were from Nintendo Wii. During the first period, participants played at a self-selected level of activity. During the second period, participants were given specific instructions for play during both active and down times within games. Participants wore a portable gas analyzer to measure energy expenditure. Resting energy expenditure was measured during session 6. Outcome measures were analyzed with 4 Game × 2 Period repeated-measures analyses of variance. Energy expenditure, measured in metabolic equivalents (METS), was greatest while playing Kinect Fighter Within. METS, enjoyment levels, and percentage of time spent in whole-body activity were greater during the period with specific instructions compared to the self-selected levels of activity, regardless of active game. When played at a self-selected level of activity, energy expenditure during the active games was similar to that of light physical activity. However, energy expenditure improved during the second period of game play showing that specific instructions created energy expenditure of moderate intensity.
Application of the Innovated Building Structure of Double Layers of Glass Curtain Wall to Energy Conservation in Penang
Authors: Liu Wen Tao 
Published: December 2018

Abstract
With the highly developed economy, many high-rise buildings are constructed in cities. In Penang, Malaysia, hundreds of high-rise buildings are erected. Because of their beauty and graceful style, two-layer glass curtain walls are super popular in these kinds of buildings. The purpose of this article is to examine the spacing between the two layers of glass curtain walls and introduce the latest research achievements for energy conservation in Penang. Based on Ecotect (Autodesk, San Rafael, CA) simulations, a 300-mm space between the two layers of the glass curtain wall can achieve maximum energy conservation. The major themes of this research include advancements in architecture structure measurements and analytical and simulation applications that provide insight into energy savings for high-rise buildings in Penang. In addition, it is hoped that these research findings can be applied to the future construction programs in Penang and in other parts of the world with similar infrastructure and climate. There has been a growing body of research and application in this field, but significant challenges and opportunities still lie ahead.

Abstract
In the life cycle of the fungal pathogen Candida albicans, the formation of filamentous cells is a differentiation process that is critically involved in host tissue invasion, and in adaptation to host cell and environmental stresses. Here, we have used the Gene Replacement And Conditional Expression library to identify genes controlling invasiveness and filamentation; conditional repression of the library revealed 69 mutants that triggered these processes. Intriguingly, the genes encoding the small ubiquitin-like modifier (SUMO) E3 ligase Mms21, and all other tested members of the sumoylation pathway, were both nonessential and capable of triggering filamentation upon repression, suggesting an important role for sumoylation in controlling filamentation in C. albicans. We have investigated Mms21 in detail. Both Mms21 nulls (mms21Δ/Δ) and SP [Siz/Pias (protein inhibitor of activated signal transducer and activator of transcription)] domain (SUMO E3 ligase domain)-deleted mutants displayed invasiveness, filamentation, and abnormal nuclear segregation; filament formation occurred even in the absence of the hyphal transcription factor Efg1. Transcriptional analysis of mms21Δ/Δ showed an increase in expression from two- to eightfold above that of the wild-type for hyphal-specific genes, including ECE1, PGA13, PGA26, HWP1, ALS1, ALS3, SOD4, SOD5, UME6, and HGC1. The Mms21-deleted mutants were unable to recover from DNA-damaging agents like methyl methane sulfonate, hydroxyurea, hydrogen peroxide, and UV radiation, suggesting that the protein is important for genotoxic stress responses. In addition, the mms21Δ/Δ mutant displayed sensitivity to cell wall and thermal stresses, and to different antifungal drugs. All these findings suggest that Mms21 plays important roles in cellular differentiation, DNA damage and cellular stress responses, and in response to antifungal drugs.
