Shade effects on overseeded bermudagrass athletic fields: II. rooting, species composition, and traction
2019
Shade from athletic stadium structures can be a significant detriment to turfgrass performance. The objective of this study was to determine the effects of shade on rooting and playing surface stability, measured as traction, on overseeded or non-overseeded bermudagrass (Cynodon spp.) turf. An experiment was established in 2013 on a mature bermudagrass [Cynodon dactylon (L.) Pers. cv. Riviera] turf that was either overseeded with perennial ryegrass (Lolium perenne L.) or non-overseeded. Shade structures were installed to create four light level treatments, including 0%, 30%, 60%, or 90% light-reducing shade cloth. The light treatments resulted in average daily light integrals (DLI) of 40.8,…
Determinants of elite-level air rifle shooting performance
2015
This study focused on identifying the most important factors determining performance in elite-level air rifle shooting technique. Forty international- and national-level shooters completed a simulated air rifle shooting competition series. From a total of 13 795 shots in 319 tests, shooting score and 17 aiming point trajectory variables were measured with an optoelectronic device and six postural balance variables were measured with force platform. Principal component analysis revealed six components in the air rifle shooting technique: aiming time, stability of hold, measurement time, cleanness of triggering, aiming accuracy, and timing of triggering. Multiple regression analysis identifie…
Asthma, allergies and respiratory symptoms in different activity groups of swimmers exercising in swimming halls
2021
Abstract Background Respiratory symptoms are common in competitive swimmers. However, among these and in swimmers at other activity levels the swimming distance, the total spent time in swimming halls and their medical background varies. Our objectives were, first, to assess their medical histories and the associations with respiratory symptoms among swimmers in different activity groups and then second, to study the pulmonary function findings and related medications in competitive swimmers who exercise in swimming hall environments the most. Methods First, 1118 participants consisting of 133 competitive-, 734 fitness- and 251 occasional swimmers answered questionnaires concerning their me…
Developments in pediatrics in 2020: choices in allergy, autoinflammatory disorders, critical care, endocrinology, genetics, infectious diseases, micr…
2021
AbstractIn this article, we describe the advances in the field of pediatrics that have been published in the Italian Journal of Pediatrics in 2020. We report progresses in understanding allergy, autoinflammatory disorders, critical care, endocrinology, genetics, infectious diseases, microbiota, neonatology, neurology, nutrition, orthopedics, respiratory tract illnesses, rheumatology in childhood.
Predicción de la lealtad de los usuarios de centros deportivos privados. Variables de gestión y bienestar subjetivo (Prediction of the loyalty of cos…
2019
Una de las finalidades más importantes en el contexto de los servicios deportivos es conocer cuáles son las intenciones futuras del usuario, por ello tratar de analizar la lealtad del usuario, se ha convertido en una de los objetivos principales dentro de la gestión del deporte, en concreto, los centros deportivos. Por ello, el objetivo es conocer que influencia tienen las demás variables de gestión y el bienestar subjetivo sobre esta dimensión que mide las intenciones futuras del usuario, como es la lealtad. La muestra de este trabajo estaba formada por 303 usuarios de la instalación deportiva (164 hombres, 139 mujeres). Para el análisis estadístico se utilizó con el programa SPSS v.23. To…
O-45 The influence of training program on the functionality of respiratory system
2016
For each individual must be appropriate life style modelling of the respiratory system functionality as well necessity for physical activity, training program, especially for amateur and professional athletes. The influence of variable factors gives implications to the amateur athletes’ body and respiratory system- health condition, supplements or necessary treatment, physical working capacity of the body, physical activity with increased function of respiratory system, cardiopulmonary interdependence, hydration, fitness level, physical abilities, training or competition period, training process and ambience. High level functionality of respiratory system decreases risk of potential interac…
ANALGESIC EFFECT OF EXTRACORPOREAL SHOCK-WAVE THERAPY ON CHRONIC TENNIS ELBOW
1996
We report a controlled, prospective study to investigate the effect of treatment by low-energy extracorporeal shock waves on pain in tennis elbow. We assigned at random 100 patients who had had symptoms for more than 12 months to two groups to receive low-energy shock-wave therapy. Group I received a total of 3000 impulses of 0.08 mJ/mm2 and group II, the control group, 30 impulses. The patients were reviewed after 3, 6 and 24 weeks. There was significant alleviation of pain and improvement of function after treatment in group I in which there was a good or excellent outcome in 48% and an acceptable result in 42% at the final review, compared with 6% and 24%, respectively, in group II.
Analytical potential of mid-infrared detection in capillary electrophoresis and liquid chromatography: a review.
2010
Literature published in the last decade concerning the use of mid-infrared spectrometry as a detection system in separation techniques employing a liquid mobile phase is reviewed. In addition to the continued use of isocratic liquid chromatographic (LC) techniques, advances in chemometric data evaluation techniques now allow the use of gradient techniques on a routine basis, thus significantly broadening the range of possible applications of LC-IR. The general trend towards miniaturized separation systems was also followed for mid-IR detection where two key developments are of special importance. Firstly, concerning on-line detection the advent of micro-fabricated flow-cells with inner volu…
Characterization of porous alumina membranes for efficient, real-time, flow through biosensing
2015
Abstract Nanofluidic sensing devices promise high performance by overcoming issues of mass transport of analyte molecules to the sensing surface, whilst micro-porous membranes promise high sensitivity due to a large surface for their capture. Anodic alumina (AAO) filter membranes allow the flow through of samples, and could be used as a convenient and readily available fluidic platform for the targeted delivering of analytes to bioreceptors immobilized on the pore walls. The relatively small pore dimensions, compared to fluidic diffusion lengths, promise highly efficient capture of analytes from the whole sample volume, enabling relatively fast sensing response times and the use of small sa…
Effect of different ergonomic supports on muscle activity of dentists during posterior composite restoration
2019
BackgroundThe aim of this study was to evaluate the effect of different ergonomic supports on the muscle activity of two trunk muscles while a group of dentists performed a common dental procedure on a phantom head, divided into three tasks.MethodsA one-way repeated measures study (ANOVA) was conducted on a group of 36 dentists. The middle trapezius and lumbar erector spinae muscles were measured with and without the use of different ergonomic supports (ergonomic stool, magnification lenses and both) using a portable surface electromyography (sEMG) device. Intraclass correlation coefficients (ICCs) and the absolute standard error of measurement (SEM) were used to establish the reliability o…
