STUDY ON THE METHODOLOGICAL DIFFERENCES IN TRAINING YOUNG TENNIS PLAYERS

It has often been said that tennis is very good in attracting new players, but less effective in helping them continue their sports activity, as there are many reasons why those who practise tennis abandon it. In classical tennis, the learning process takes place over several years, being a long-lasting activity (6 -8 years). Tennis 10 is a program that was created and implemented by the International Tennis Federation (ITF) in the early 2000s as part of a campaign called "Tennis Play And Stay". It was officially released in February 2007 and its purpose was to increase the practice of tennis throughout the world. The Tennis Play and Stay campaign aimed at promoting tennis as a sports game easy to play, good to have fun and keep people healthy and making sure that all beginner players could serve and hit the ball from the first lesson. Through this work we have discovered that the means used in Tennis 10 are perceived as superior by the specialists in Romania, compared to the standard methodology in developing physical, technical, tactical training and in the initiation of athletes in the competitive environment.

Frequency of microsatellite instability (MSI) in upper tract urothelial carcinoma: comparison of the Bethesda panel and the Idylla MSI assay in a consecutively collected, multi-institutional cohort

AimsUpper tract urothelial carcinoma (UTUC) is a rare malignancy with a poor prognosis which occurs sporadically or in few cases results from a genetic disorder called Lynch syndrome. Recently, examination of microsatellite instability (MSI) has gained importance as a biomarker: MSI tumours are associated with a better response to immunomodulative therapies. Limited data are known about the prevalence of MSI in UTUC. New detection methods using the fully automated Idylla MSI Assay facilitate analysis of increased patient numbers.MethodsWe investigated the frequency of MSI in a multi-institutional cohort of 243 consecutively collected UTUC samples using standard methodology (Bethesda panel), along with immunohistochemistry of mismatch repair (MMR) proteins. The same tumour cohort was retested using the Idylla MSI Assay by Biocartis.ResultsUsing standard methodology, 230/243 tumours were detected as microsatellite stable (MSS), 4/243 tumours as MSI and 9/243 samples as invalid. In comparison, the Idylla MSI Assay identified four additional tumours as MSS, equalling 234/243 tumours; 4/243 were classified as MSI and only 5/243 cases as invalid. At the immunohistochemical level, MSI results were supported in all available cases with a loss in MMR proteins. The overall concordance between the standard and the Idylla MSI Assay was 98.35%. Time to result differed between 3 hours for Idylla MSI Assay and 2 days with the standard methodology.ConclusionOur data indicate a low incidence rate of MSI tumours in patients with UTUC. Furthermore, our findings highlight that Idylla MSI Assay can be applied as an alternative method of MSI analysis for UTUC.

COVID-19 on the Ground: Managing the Heritage Sites of a Pandemic

The standard methodology for the assessment of cultural heritage significance relies on hindsight, with a passage of time elapsed between the creation of the site or object and its assessment. There are, however, cases where heritage significance is instant (e.g., sites associated with the first Moon landing). This paper argues that hindsight will not be required to determine that the COVID-19 pandemic will come to be considered as a significant historic event, as COVID-19 has already manifested itself as a social, cultural and economic disruptor on a global scale with a mortality in the millions. Heritage professionals have the unique opportunity to assess and document places and structures associated with the pandemic, that are poised to be worthy of a heritage listing in the near future, while they are still in use and function as intended. This paper discusses the nature of the sites and structures and explores possible management approaches to safeguard evidence of the pandemic for future generations.

Social-scientific criticism in Nigerian New Testament scholarship

The use of the social sciences in the interpretation of the New Testament emerged from the 1970s and has become a standard methodology for interpreting the New Testament. However, it has not been significantly used in the interpretation of the New Testament in Nigeria by biblical scholars. This article discusses what social-scientific criticism is and the need for its application in the interpretation of the New Testament by Nigerian New Testament scholars for a better understanding of the New Testament and the people, beliefs and teachings it presents and contextualisation in the face of changing contexts of Christianity in Nigeria.Contribution: As far as we know, this article is the first one written on using social-scientific criticism to interpret the New Testament in the Nigerian context. It therefore contributes to the need for a multidisciplinary approach to interpreting the New Testament in Nigeria in particular and Africa in general. It therefore contributes also on methodological considerations with regard to interpreting the New Testament.

Sperm mitochondrial DNA copy numbers in normal and abnormal semen analysis: a systematic review and meta-analysis.

Background: Normal mature sperm have a considerably reduced number of mitochondria which provide the energy required for progressive sperm motility. Literature suggests that disorders of sperm motility may be linked to abnormal sperm mitochondrial number and function. Objectives: To summarise the evidence from literature regarding the association of mitochondrial DNA copy numbers and semen quality with a particular emphasis on the spermatozoa motility. Search strategy: Standard methodology recommended by Cochrane. Selection criteria: All published primary research reporting on differences in mitochondrial DNA copy numbers between the sperm of males with a normal and abnormal semen analysis. Data collection and analysis: Using standard methodology recommended by Cochrane we pooled results using a random effects model and the findings were reported as a standardised mean difference. Main results: We included 10 trials. The primary outcome was sperm mitochondrial DNA copy numbers. A meta-analysis including five studies showed significantly higher mitochondrial DNA copy numbers in abnormal semen analysis as compared to normal semen analysis(SMD 1.08, 95% CI 0.74-1.43). Three other studies not included in the meta-analysis showed a significant negative correlation between mitochondrial DNA copy numbers and semen parameters. The quality of evidence was assessed as good to very good in 60% of studies. Conclusions: Our review demonstrates significantly higher mitochondrial DNA in human sperm cells of men with abnormal semen analysis in comparison to men with normal semen analysis.

What All Do Audio Transformer Models Hear? Probing Acoustic Representations for Language Delivery and Its Structure

In recent times, BERT based transformer models have become an inseparable part of the 'tech stack' of text processing models. Similar progress is being observed in the speech domain with a multitude of models observing state-of-the-art results by using audio transformer models to encode speech. This begs the question of what are these audio transformer models learning. Moreover, although the standard methodology is to choose the last layer embedding for any downstream task, but is it the optimal choice? We try to answer these questions for the two recent audio transformer models, Mockingjay and wave2vec2.0. We compare them on a comprehensive set of language delivery and structure features including audio, fluency and pronunciation features. Additionally, we probe the audio models' understanding of textual surface, syntax, and semantic features and compare them to BERT. We do this over exhaustive settings for native, non-native, synthetic, read and spontaneous speech datasets

Applications of Mechanochemistry for the Synthesis of DNA on Ionic Liquid Supports

<p>The standard methodology for the synthesis of oligonucleotides is the solid-phase method. Here, we report the first case of mechanochemistry being directly applied to the synthesis of a dinucleotide on a soluble support. While mechanochemistry eliminates the need to solubilise a supported oligomer in solution phase for phosphoramidite coupling, the support still confers the benefit of being able to purify the product by precipitation, or by simple liquid-liquid extractions as needed. Furthermore, this study also explores the use of mechanochemistry in the initial functionalisation of the ionic liquid support with a nucleoside monomer.</p>

175 The Suitability of Autoclave and Pressure Cooker Washing Methods in Comparison to ANKOM200 to Determine Neutral Detergent Fiber Using Different Feedstuffs and Washing Solutions

The use of the in vitro gas production (IVGP) technique requires accurate determination of neutral detergent fiber (NDF) residue. However, the NDF determination using standard procedures are not always feasible for IVGP; thus requiring micro-NDF methods, which need autoclave (AC) and pressure cooker (PC) to boil the solution. A complete randomized design using a 3×3 factorial arrangement was implemented to investigate the effect of washing methods (WM: AC, PC, or ANKOM200) and solution ratios (WS: 100 mL neutral detergent solution (ND), 150 mL ND, or 100 mL H2O/g sample) to determine NDF residues, assuming ANKOM200 and 100 mL ND/g as the standard methodology. Each factor combination was performed in triplicate with a replicate being comprised of 12 bottles or bags (two blanks and five feedstuffs in duplicate). Feedstuffs were: alfalfa hay (AH), bermudagrass hay (BH), two high-forage rations (G1 and G2), and a high-concentrate ration (FR). Following each run, bottles were filtered to obtain the NDF. Data were analyzed by diet using a random coefficients model. An interaction of WM ′ WS was present for AH and G1 (P &lt; 0.01), G2 and FR had tendencies (P = 0.08 and 0.06, respectively), whereas BH demonstrated no interaction (P = 0.37). The PC with 100 mL or 150 mL did not differ from the standard methodology for AH, G1, G2, and FR. The BH demonstrated differences between WM and WS (P &lt; 0.01). The PC had lower NDF residue compared to the AC and ANKOM200, whereas H2O had substantially greater NDF residue relative to both ND ratios. We concluded that H2O is not a suitable substitute for ND solution regardless of the feedstuff. Both micro-NDF washing methods may be satisfactory depending on the type of feedstuff used but further investigation is required.
