Background: One of the most sought-after skills for performance in team sports is change of direction. Training the physical qualities of strength, speed, and power has been used to improve change of direction. These qualities of change of direction have been studied extensively for the last 20 years, and their influence is still questioned. Additionally, it is currently unknown how moderating training variables affect COD performance. Objective: This study examines the impact of strength, power, and speed training on change of direction performance. Method: Following the PRISMA guidelines, a meta-analysis was conducted. Electronic databases were searched for studies conducted from 1991 to April 2021. All studies identified for inclusion were peer-reviewed and published in English and Spanish and used an athlete population as participants. For all analyses, a significance level is set at p < 0.05. Results: Sixty-six articles were included in this meta-analysis. Two hundred fifty-one effect sizes were calculated, representing 2056 participants aged between 12 and 25 years. The global effect size (ES) for each quality is reported and Cochran's Q test: Strength (N = 48) ES: 0.844 Q = 77.63 (95%CI: 0.65;1.07); Speed (N = 17) ES: 0.70 Q = 5.69 (CI95% = 0.35;1.05); Power (N = 49) ES: 0.85 Q = 47.58 (CI95% = 0.64;1.06); Agility (N = 57) ES: 1.05 Q = 79.63 (CI95% = 0.86;1.24); Combined training (N = 13) ES: 0.51 Q = 13.79 (CI95% = 0.14;0.93), and the Control Group (N = 67) ES: 0.53 Q = 47.40 (IC95% =

Purpose: The neurotransmitter serotonin has a strong effect on behaviour and motor control. Regarding motor control, serotonin contributes to the development of fatigue and is also involved in the ability of motor neurones to operate across a large range of forces (gain control).

Introducing novel functionalities to state-of-the-art batteries has the potential to immensely enrich energy conversion chemistry. Here, we show a Zn-air battery concept wherein pollutant degradation is paired with electric power production facilitated by the in situ transformation of hydrogen peroxide (H2O2) produced on battery discharge to extremely reactive hydroxyl (˙OH) radical via Fenton's reaction. The battery delivered an open circuit voltage of nearly 1.3 V, a peak power density of nearly 55 mW cm

This study examines the potential of the soft computing technique, namely, multiple linear regression (MLR), genetic programming (GP), classification and regression trees (CART) and GA-ENN (genetic algorithm-emotional neuron network), to predict the ultimate bearing capacity (UBC) of cohesionless soils beneath shallow foundations. For the first time, two grey-box AI models, GP and CART, and one hybrid AI model, GA-ENN, were used in the literature to predict UBC. The inputs of the model are the width of footing (B), depth of footing (D), footing geometry (ratio of length to width, L/B), unit weight of sand (

Learning about Indigenous research paradigms and methodologies offers insights and reflexive opportunities for those who seek to improve their research practice. This paper explores how research at the "interface" can enrich scholarly inquiry across the academy. Whilst a single paper cannot do justice to the sophistication and nuance of Indigenous methodologies, as an authorship team of one Indigenous and two non-Indigenous academics and through our established relationship and subsequent conversations, we present in this paper seven distilled methodological learnings that can enrich standard qualitative research practice. We predominantly explored the work of Indigenous scholars worldwide and, where relevant, have drawn on non-Indigenous scholars when there may be "interface" compatibilities. We also build off some of our previous work, such as Andrews (2020a, 2020b, 2021) and Bolton and Andrews.

Erd.os proved that every real number is the sum of two Liouville numbers. A set W of complex numbers is said to have the Erd.os property if every real number is the sum of two members of W. Mahler divided the set of all transcendental numbers into three disjoint classes S, T and U such that, in particular, any two complex numbers which are algebraically dependent lie in the same class. The set of Liouville numbers is a proper subset of the set U and has Lebesgue measure zero. It is proved here, using a theorem of Weil on locally compact groups, that if m

In 1844, Joseph Liouville proved the existence of transcendental numbers. He introduced the set L of numbers, now known as Liouville numbers, and showed that they are all transcendental. It is known that L has cardinality c, the cardinality of the continuum, and is a dense G

Conical picks are widely used as cutting tools in shearers and roadheaders, and the mean cutting force (MCF) is one of the important parameters affecting conical pick performance. As MCF depends on a number of parameters and due to that the existing empirical and theoretical formulas and numerical modelling are not sufficient enough and reliable to predict MCF in a proficient manner. So, in this research, a novel intelligent model based on a random forest algorithm (RF) and a heuristic algorithm called the salp swarm algorithm (SSA) have been applied to determine the optimal hyper-parameters in RF, and root mean square error is used as a fitness function. A total of 188 data samples including 50 rock types and seven parameters (tensile strength of the rock

This paper presents research related to the estimation of the precipitation fraction in the soil water of a sloped vineyard at the SUPREHILL Critical Zone Observatory (CZO) in Zagreb, Croatia. Numerous investigations have shown that exploration of hillslope soils can be very challenging due to the existence of heterogeneity and different soil properties, as well as due to anthropogenically induced processes, which can affect precipitation infiltration and soil water flow. Within this research, physicochemical soil properties, soil water content (SWC), and isotopic composition of soil water and precipitation (

Aims and objective: To assess the implementation of standards by Australian Nursing higher education providers as set by accrediting and regulating bodies and to identify any barriers or enablers to optimizing Professional Experience Placement. To recommend strategies for safeguarding and improving any identified enablers as well as mitigating factors for any identified barriers. Background: Professional Experience Placement is an essential element of all accredited Nursing Programs in Australia. The Australian Nursing and Midwifery Accreditation Council is responsible for developing accreditation standards and mandates minimum of 800 h of Professional Experience Placement scaffolded across curriculum which some Higher Education Providers set as their exact baseline for clinical placement duration. Design: Descriptive study using; questionnaire survey with qualitative thematic analysis and CROSS checklist. Method: Quantitative method with descriptive qualitative thematic analysis and purposive sampling was used to target 37 higher education institutions that offer BN and BN/BM programs, 33 of these institutions were randomly selected for inclusion. Data was collected over a six-week period from 24th May to 4th July 2022 using Qualtrics online survey. Results: Out of the 33 Higher Education providers who were invited to participate, 51.5 % (n = 17) responded. The respondent's demographics were: 94 % Bachelor of Nursing only placements coordinators while one respondent reported covering both Bachelor of Nursing and Bachelor of Midwifery; Most of the respondents (65 %) were in 40–55 years age group. The respondents reported to have overall responsibility across one to 6 campuses (Mean = 2.2) and having support/administrative staffs ranging from 0 to 15 (Mean = 4.11). Student population among the institutions ranged from 500 to 7500 with a mean of 2365.38. The number of campuses covered had statistically significant relationship with the student population (p < 0.001; 0.392–0.929 confidence interval) however no statistically significant relationship with the number of administrative staff allocated (p = 0.319;
