The article reveals the essence of the content and basic theoretical principles of selection and sports training of young basketball players based on biological age, substantiates the need to take into account the biological age of young basketball players in sports training. The main features of the initial selection of young basketball players are identified, systematized and characterized. It is shown that the problem of selection of athletes is very multifaceted. It affects many aspects: social, psychological, pedagogical, philosophical and others. On some issues of selection there are more or less clear ideas from the theory, on others – they are still in the process of formation. The idea of the relationship between physical and technical fitness of young athletes in the selection for classes in the basketball section, their sports training in the training of young basketball players, taking into account the biological age, was expanded. A small-scale and quantitatively selective experiment was conducted, which provided an opportunity to solve the objectives of the study. The importance of using different methods and means of selection, the importance of this process to achieve high results in basketball give grounds for further scientifically sound search for a solution to this problem.

ABSTRACTIt is important to understand the relationship between antibiotic exposure and the selection of drug resistance in the context of therapy exposure. We sought to identify the ceftolozane-tazobactam exposure necessary to prevent the amplification of drug-resistant bacterial subpopulations in a hollow-fiber infection model. TwoPseudomonas aeruginosachallenge isolates were selected for study, a wild-type ATCC strain (ceftolozane-tazobactam MIC, 0.5 mg/liter) and a clinical isolate (ceftolozane-tazobactam MIC, 4 mg/liter). The experiment duration was 10 days, and the ceftolozane-tazobactam dose ratio (2:1) and dosing interval (every 8 h) were selected to approximate those expected to be used clinically. The studied ceftolozane-tazobactam dosing regimens ranged from 62.5/31.25 to 2,000/1,000 mg per dose in step fold dilutions. Negative-control arms included no treatment and tazobactam at 500 mg every 8 h. Positive-control arms included ceftolozane at 1 g every 8 h and piperacillin-tazobactam dosed at 4.5 g every 6 h. For the wild-type ATCC strain, resistance was not selected by any ceftolozane-tazobactam regimen evaluated. For the clinical isolate, an inverted-U-shaped function best described the relationship between the amplification of a drug-resistant subpopulation and drug exposure. The least (62.5/31.25 mg) and most (2,000/1,000 mg) intensive ceftolozane-tazobactam dosing regimens did not select for drug resistance. Drug resistance selection was observed with intermediately intensive dosing regimens (125/62.5 through 1,000/500 mg). For the intermediately intensive ceftolozane-tazobactam dosing regimens, the duration until the selection for drug resistance increased with dose regimen intensity. These data support the selection of ceftolozane-tazobactam dosing regimens that minimize the potential for on-therapy drug resistance selection.

1. The relationship between first lactation performance and the ability of individual animals to survive to the second lactation has been examined in Friesian and Ayrshire populations in an attempt to isolate the main determinants of survival, and to rationalise an apparently complicated selection procedure.2. Low milk yield was the most important single cause of culling in the first lactation, though the two breeds differed considerably in the relative importance of milk yield in the selection programme. Natural wastage, caused by factors beyond the control of the farmer, accounted for the disposal of 5·7% of the population during the first lactation. Selection for butterfat was marginal in both populations, and could only be detected at extreme butterfat percentages, where high butterfat tended to compensate for a poor milk yield, and low butterfat to confirm a decision to cull an average yielding animal. Survival was not significantly affected either by the size of the herd or by the age at calving.3. The proportion culled, and the intensity and effectiveness of selection for milk yield, were inversely related to the level of herd performance, and were greater in summer calving animals than in winter calvers.4. The analysis indicated that selection for milk yield in different environments could be adequately described in terms of the Normal Curve. Yield-survival curves were computed and compared for groups of animals in different herd and calving season environments. When milk yield was expressed in terms of the deviation from the herd-year average, it was found that summer calvers, and animals in low yielding herds, had to demonstrate a productive capacity of far greater individual merit, if their chances of survival were to match those of their winter calving herdmates, and those of their contemporaries in higher yielding herds. When milk yield was expressed in absolute terms the survival of individual animals of similar yield was comparable in all herd and season environments. It was concluded that all the herds included in the analysis had been subject to the same absolute standards of milk yield in the selection of first calvers.

Objective To evaluate specified biomedical, socio-economic, and psychosocial criteria as predictors of therapeutic success to optimize patient selection for continuous ambulatory peritoneal dialysis (CAPD) in a developing country. Design A restrospective cohort study investigating the relationship between episodes of peritonitis and exitsite infection, and predetermined biomedical, socioeconomic, and psychosocial data. Setting A CAPD unit in a large tertiary care teaching hospital. Patients AI1132 patients entering the CAPD program between 1987 and 1991. Results Overall mean survival time on CAPD was 17.3 months. Peritonitis rates were high, especially among blacks. Multivariate analysis demonstrated that increased peritonitis rates were associated with age, black race, diabetes, and strongly so with several psychosocial factors. Because being black was strongly linked to poor socioeconomic conditions, repeat analysis excluding blacks showed the same associations with the above variables, but, additionally, several socioeconomic factors were associated with high peritonitis rates. No significant explanatory variables were shown for exit-site infections. Conclusions The association of biomedical, socio-economic, and psychosocial variables with high peritonitis rates has important implications for the selection of patients for CAPD in this setting.

Within Sulfur Recovery Units (SRU), many equipment and piping items are built with internal refractory linings, but between the various process areas, the refractory is being used for completely different functions. Understanding the “purpose” of the refractory is important for both the initial selection of the optimum type of refractory, and also for repair decisions whenever refractory damage is found during turnarounds. This paper will describe each area where refractory is used, the operating and turnaround conditions, and the four unique purposes of the refractory to provide a mechanistic understanding of the function of refractory. It will also discuss the relationship between the purpose and repair philosophies for use as a general guideline.

Abstract Introduction The relationship between the chemical composition of food products and their sensory profile is a complex association confronting many challenges. However, new untargeted methodologies are helping correlate metabolites with sensory characteristics in a simpler manner. Nevertheless, in the pilot phase of a project, where only a small set of products are used to explore the relationships, choices have to be made about the most appropriate untargeted metabolomics methodology. Objective To provide a framework for selecting a metabolite-sensory methodology based on: the quality of measurements, the relevance of the detected metabolites in terms of distinguishing between products or in terms of whether they can be related to the sensory attributes of the products. Methods In this paper we introduce a systematic approach to explore all these different aspects driving the choice for the most appropriate metabolomics method. Results As an example we have used a tomato soup project where the choice between two sampling methods (SPME and SBSE) had to be made. The results are not always consistently pointing to the same method as being the best. SPME was able to detect metabolites with a better precision, SBSE seemed to be able to provide a better distinction between the soups. Conclusion The three levels of comparison provide information on how the methods could perform in a follow up study and will help the researcher to make a final selection for the most appropriate method based on their strengths and weaknesses.

Competition during the sports training process should aid young athletes’ overall development. The aim of this study was to ascertain the levels of competitive anxiety in athletes who practice basketball at the Real Madrid Foundation (RMF)’s Social-Sports Schools, and to analyze whether any differences exist in regard to anxiety in the various subscales that take into account gender, participation in the RMF’s internal competitions, and basketball modalities (mini basketball/basketball). The study sample consisted of 320 players (224 boys and 96 girls) belonging to the following different age groups: 8–9-year-olds, 10–11-year-olds, 12–13-year-olds, and 14–15-year-olds (M = 10.54; SD = 1.92). The Sport Anxiety Scale-2 (SAS-2) was used in the version translated and validated in Spanish. It was found that the athletes displayed low levels of competitive anxiety in all three subscales. No significant differences were observed between the genders, nor between basketball modalities (mini basketball/basketball). Finally, a positive correlation was observed between the various subscales.

Prior to mid-July, Daphnia pulicaria in yellow perch (Perca flavescens) fry stomachs were smaller than those in plankton collections but after this date mean lengths of D. pulicaria in stomachs and collections were similar indicating an initial selection for small D. pulicaria by the fish. The relation between D. pulicaria body depth and perch mouth gape width indicated that perch fry less than 18 mm long, a length attained in mid-July, could not readily ingest D. pulicaria with body depths greater than 0.7 mm (1.3 mm long). The heterogenic relation between growth in mouth and body size enabled perch fry in West Blue Lake to quickly utilize, as an energy source, the abundant D. pulicaria population.

Abstract Background: The ablation of the coronary sinus (CS) is becoming more and more important in accessory pathway-related supraventricular tachycardia ablation. In comparison with temperature-controlled catheters (TCC), irrigated-tip catheter (ITC) are more expensive and cause more damage in accessory pathway-related supraventricular tachycardia ablation. We intended to develop a new method for the reasonable selection of electrode for coronary sinus(CS) ablation via assessing the relationship between the accessory pathway (AP) potential and time of successful ablation. Methods：Among the patients who had detected the bypass potential during radiofrequency ablation between 1/1/2015 and 12/31/2019. TCC was performed in 330 patients receiving endocardial ablation. 30 patients underwent radiofrequency catheter ablation (RFCA) in CS. The relationship between AP potential and time of successful ablation was analyzed. Results：330 cases of TCC ablation within the endocardium revealed that the amplitude of AP potential was significantly and negatively correlated with the time of successful ablation (r = -0.79, p < 0.001). In CS ablation, the median baseline amplitude of the AP potentials in patients with successful TCC ablation was higher than that in patients with ITC following TCC ablation failure (p = 0.02). The optimal cutoff value of the amplitude of the AP potential to guide the selection of a catheter for ablation was 1.07 mV, and the sensitivity and specificity were 80% and 90%, respectively. Conclusion：The AP potential is helpful for the electrode selection in CS ablation.

Results have been presented from a small scale investigation into operational and theoretical aspects of progeny testing Down rams as sires of crossbred fat lambs. Twenty-six Suffolk rams were evaluated from the growth records of 922 lambs out of Border Leicester × Cheviot ewes. In addition measurements were recorded on 260 carcasses. Significant differences were found between corrected progeny means, which were equivalent t o heritabilities of between 0·03 and 0·13 for live-weights up to 15 weeks, and o t higher values for skeletal measurements.A scheme for the selection of Down rams was considered which involved measuring the individual performance of all ram lambs and then progeny testing the best of these by measuring a fixed total number of crossbred lambs. It was concluded that the proportion to be progeny tested could be varied within quite wide limits without seriously changing the genetic merit of the selected group.
