Effect of Short-Term Storage Temperature on Mechanical Properties of ‘Istanbul’ Medlar

The study investigated the effect of short-term storage time on the mechanical (rupture force, rupture energy, deformation) properties of the ‘Istanbul’ medlar cultivar grafted on Quince A (QA) and Quince Province BA29 (BA29) quince clone rootstock. The study gives the average values of the physical properties (weight, size, geometric mean diameter, sphericity, surface area, true density, bulk density, and porosity) of the ‘Istanbul’ medlar cultivar. The changes in breaking force, breaking energy, and deformation values of 'Istanbul' medlar varieties stored at room temperature (251 °C) and cold storage (41 °C) for 5 days were investigated. Separate measurements were made for skin and skinless fruits. The average rupture force value of fruits of the ‘Istanbul’ medlar cultivar stored at 25 °C was determined as 8.82 N, deformation 4.66 mm, and rupture energy 0.035 J. The average rupture force value of the fruits of the ‘Istanbul’ medlar cultivar stored at 4 °C was determined as 10.06 N, deformation 5.16 mm, and rupture energy 0.043 J. It was found that the storage conditions had a statistically significant effect on the rupture force, rupture energy, and deformation values of the QA and BA29 rootstocks of the ‘Istanbul’ medlar cultivar (P≤0.001).

Was I thinking about thinking about the task? Measurement issues with self-reports of task-related and task-unrelated thoughts

In two studies we examined participants self-reports of their cognitive state after performing tasks. The reports of cognitive state included separate single item measures of task-related and task-unrelated thoughts framed as opposing sets (thoughts about X and –X). In study 1, we examined two data sets from previously published research. The correlation between task-related and task-unrelated thoughts was ~ r = −.25. In addition, the two items loaded onto separate factors when they were combined with other measures from the Short Task Relevant Evaluation of Stress State (STRESS). In study 2, 33 participants played a simulated natural disaster strategy game for five sessions and after each session they self-reported their cognitive state during the game. The correlation between task-related and task-unrelated thoughts at the individual level was also low, ~r = −.24. Participants may have difficulties accurately rating their thought content post-engaging in a task.

From observer-dependent facts to frame-dependent measurement records in Wigner friend scenarios

The description of Wigner friend scenarios —in which external agents describe a closed laboratory containing a friend making a measurement— remains problematic due to the ambiguous nature of quantum measurements. One option is to endorse assumptions leading to observer-dependent facts, given that the friend's measurement outcome is not defined from the point of view of the external observers. We introduce in this work a model in a relativistic context showing that these assumptions can also lead to measurement records that depend on the inertial reference frame in which the agents make their observations. Our model is based on an entangled pair shared by the friend and a distant agent performing space-like separated measurements. An external observer at rest relative to the closed laboratory and observers in a moving frame do not agree on the observed records, which are not Lorentz transforms of one another.

BCG alignment with the locations of cluster members and the large-scale structure out to 10 R200

ABSTRACT Using a sample of >200 clusters, each with typically 100–200 spectroscopically confirmed cluster members, we search for a signal of alignment between the position angle (PA) of the Brightest Cluster Galaxy (BCG) and the distribution of cluster members on the sky about the cluster centre out to projected distances of 3 R200. The deep spectroscopy, combined with corrections for spectroscopic incompleteness, makes our sample ideal to determine alignment signal strengths. We also use an SDSS based skeleton of the filamentary large-scale structure (LSS), and measure BCG alignment with the location of the LSS skeleton segments on the sky out to projected distances of 10 R200. The alignment signal is measured using three separate statistical measures; Rao’s spacing test (U), Kuiper’s V parameter (V), and the Binomial probability test (P). The significance of the BCG alignment signal with both cluster members and LSS segments is extremely high (1 in a million chance or less to be drawn randomly from a uniform distribution). We investigate a wide set of parameters that may influence the strength of the alignment signal. Clusters with more elliptical-shaped BCGs show stronger alignment with both their cluster members and LSS segments. Also, selecting clusters with closely connected filaments, or using a luminosity-weighted LSS skeleton, increases the alignment signal significantly. Alignment strength decreases with increasing projected distance. Combined, these results provide strong evidence for the growth of clusters and their BCGs by preferential feeding along the direction of the filaments in which they are embedded.

Radiological examination of the skull of Siirt-coloured mohair goat, Romanov and Hamdani sheep.

The skull is a vitally important complex structure formed by the combination of many bones. Craniometric studies are performed with various imaging methods to determine morphometric characteristics in animals. One of these methods is radiography. In our study, skulls of 14 Hamdani sheep, 20 Siirt-coloured mohair goats and 20 Romanov sheep breeds were used. Skull sections were taken with a computed tomography device and saved in DICOM format. Nine separate measurements and six index calculations were made from the images. In the study, firstly, the gender difference was ignored and the similarities and differences between the species were recorded. In addition, gender differences were determined statistically, without making any distinction between species. Correlation analysis was performed to compare measurement parameters between animal species. As a result of the study, the highest skull length (SL) and cranial length (CL) values were determined in the Siirt-coloured mohair goat. It was determined that the difference between Romanov sheep and Siirt-coloured mohair goat in CL parameter was not statistically significant (p > 0.05). In addition, a statistically significant difference was observed between the Romanov sheep breed and the Hamdani sheep breed (p < 0.01). The external length of the cranium (ELC) measurement parameter was found to have a statistically significant difference in three animals (p < 0.01). According to the results of the correlation analysis, the highest correlation value was determined between cranial width (CW) and CL parameters (r = 0.920). When the species difference was ignored, and the statistical difference of the internal height of the cranium (IHC) parameter was found to be significant between female and male animals (p < 0.05). In addition, it was determined that SL, CW and internal cranium index (ICI) parameters had a significant difference depending on sex (p < 0.01). It is foreseen that the obtained data can be used in sciences such as zoo archaeology, anatomy, surgery and forensic medicine.

Cognitive processing biases associated with fear of childbirth

Fear of childbirth (FOC) is a phobic-like response concerning the prospect of giving birth. FOC can have negative implications for women during pregnancy and can impact their birthing experience. Cognitive processing biases (e.g., difficulty disengaging from threatening information, interpreting ambiguous information as threatening, and preferentially recalling threatening content) have previously been found to maintain general anxiety and low mood. To date, there has been no research assessing these attention, interpretation, and memory biases and their relationship with FOC in pregnant women. Accordingly, in this cross-sectional study, participants who were at least 12 weeks pregnant (n = 116), recruited through a local hospital trust, completed tasks assessing attention (emotional Stroop task), interpretation (scrambled sentences test), and explicit memory (recognition task) biases with materials including FOC-related content. They also completed three separate measures of FOC and measures of low mood, general anxiety, worry, and rumination. We found that a negative interpretation bias (but not attention or explicit memory biases) was associated with higher levels of FOC. These findings indicate that women presenting with higher FOC are more likely to demonstrate negative interpretation biases for ambiguous information relating to childbirth, which may inform research developing interventions to support women presenting with FOC.

Green chemistry-based fabrication of hollow fiber and flat sheet polyimide membranes for CO2/CH4 separation

In this work, the successful fabrication of polymeric hollow fiber (HF) and flat sheet (FS) membranes was examined by employing γ-butyrolactone (GBL)-a green and environmentally friendly solvent- for the polymer's dissolution following the principles of green chemistry and sustainability regarding the membrane preparation. In addition, the ternary phase diagram of the P84/GBL/water was constructed and the viscosity of dope solution was measured for different concentrations and temperatures. Their morphological characteristics of the prepared polyimide membranes were investigated through SEM analysis. CO2/CH4 separation measurements under continuous flow were performed to evaluate the efficiency of the membranes for a binary 10/90 vol.% CO2/CH4 gas mixture. The developed green HF and FS membranes exhibited comparable, and in some cases even superior, performance compared to membranes prepared using the conventional and highly toxic NMP solvent, making them highly promising candidates for CO2/CH4 separation, with a real mixture separation factor of ∼58.

The autonomic and nociceptive response to acute experimental stress is impaired in people with knee osteoarthritis: A preliminary study

ObjectiveAlterations in autonomic function are evident in some chronic pain conditions but have not been thoroughly examined in people with osteoarthritis (OA). The study aimed to examine resting autonomic nervous system (ANS) function in people with knee OA, and the response of the autonomic and nociceptive systems to acute stress. MethodsA preliminary cross-sectional study was undertaken involving people with knee OA (n = 14), fibromyalgia (n = 13), and pain-free controls (n = 15). The sympathetic and parasympathetic components of the ANS were assessed through measures of pre-ejection period (PEP), skin conductance level (SCL), and high frequency heart rate variability (HF HRV). The nociceptive system was assessed through pain ratings associated with a tonic heat pain stimulus. In separate sessions, ANS and heat pain measures were assessed at rest and in response to nociceptive and mental arithmetic stressors. ResultsThe knee OA group showed reduced HF HRV at rest and reduced modulation in response to stress. Resting PEP and SCL were normal in the knee OA group but PEP modulation was impaired in both chronic pain groups during nociceptive stress. The expected reduction in tonic heat pain ratings in response to stress was lacking in the knee OA and FM groups. ConclusionPreliminary evidence shows impaired parasympathetic nervous system function at rest and in response to nociceptive and mental stress in people with knee OA, with some evidence of altered sympathetic nervous system function. Impaired ANS function could contribute to ongoing pain experienced, and interventions that target ANS function could be beneficial.

An adaptable end-to-end maintenance performance diagnostic framework

PurposeThis paper proposes a progressive, multi-level framework for diagnosing maintenance performance: rapid performance health checks of key performance for different equipment groups and end-to-end process diagnostics to further locate potential performance issues. A question-based performance evaluation approach is introduced to support the selection and derivation of case-specific indicators based on diagnostic aspects.Design/methodology/approachThe case research method is used to develop the proposed framework. The generic parts of the framework are built on existing maintenance performance measurement theories through a literature review. In the case study, empirical maintenance data of 196 emergency shutdown valves (ESDVs) are collected over a two-year period to support the development and validation of the proposed approach.FindingsTo improve processes, companies need a separate performance measurement structure. This paper suggests a hierarchical model in four layers (objective, domain, aspect and performance measurement) to facilitate the selection and derivation of indicators, which could potentially reduce management complexity and help prioritize continuous performance improvement. Examples of new indicators are derived from a case study that includes 196 ESDVs at an offshore oil and gas production plant.Originality/valueMethodological approaches to deriving various performance indicators have rarely been addressed in the maintenance field. The proposed diagnostic framework provides a structured way to identify and locate process performance issues by creating indicators that can bridge generic evaluation aspects and maintenance data. The framework is highly adaptive as data availability functions are used as inputs to generate indicators instead of passively filtering out non-applicable existing indicators.

Outcomes of Composite Grafts for Pediatric Fingertip Amputations: A Systematic Review.

Introduction The aim of this study was to explore the outcomes of composite grafts in fingertip amputations in children as well as the contributing factors that may affect outcomes. Methods Literature search was conducted across six databases in March 2022 to select studies on the use of composite grafts on fingertip amputations in the pediatric population. Results Twelve articles with 735 composite grafts were identified for review. Most fingertip injuries occurred in the less than 5-year age group and were due to crush type injuries. In studies that reported "complete" graft take as a separate outcome measure, 17.3% of fingertips with this result were observed. In the studies that reported "complete" and "partial" graft take together as an outcome measure, 81.6% of fingertips achieved this outcome. A lower proportion of failed graft take was observed in more distal fingertip amputations. Infection (3.8%) and nail abnormalities (3.4%) were the most common complications following composite grafting. Conclusion Composite grafting can be considered as a useful method of treatment in this population. Clinicians should be aware of the potential complications following this method of treatment such as infection and nail abnormalities. More proximal fingertip amputations may warrant other surgical interventions (beyond Level II on the modified Ishikawa/Ishikawa classification). Significant heterogeneity was observed within the studies, mainly due to lack of standardization in assessment and reporting of outcomes.

Ultrasound imaging of the phrenic nerve at the scalene muscle level.

The aim of this study is to utilize ultrasound to evaluate the normal cross-sectional area (CSA) of the phrenic nerve (PN), at the level of the anterior scalene muscle. The study included 62 PNs in 31 healthy subjects (13 men, 18 women); mean age, 36.6 years; mean height, 161.1 cm; mean weight, 69.6 kg; and mean body mass index 25.8 kg/m2. High-resolution ultrasound images of the bilateral PNs were obtained by a radiologist with 15 years of experience in neuromusculoskeletal ultrasound. Three separate CSA measurements for the bilateral PNs bilaterally were obtained. Images were also reviewed by an experienced neurologist to evaluate for inter-rater variability. The mean CSA of the right PN was 0.54 mm2 ± 0.16. The mean CSA of the left PN was 0.53 mm2 ± 0.18. We believe that the reference values for the normal CSA of the PNs obtained in our study could help in the sonographic evaluation of PN enlargement, as it relates to the diagnosis of various diseases affecting the PN. Furthermore, knowledge of its location and size, at the level of the scalene muscle, could help prevent PN-related complications during interventional procedures in that area. Additionally, for each participant, demographic information of age and gender as well as body mass index, weight, and height were documented.

Transcranial focused ultrasound stimulation of cortical and thalamic somatosensory areas in human.

The effects of transcranial focused ultrasound (FUS) stimulation of the primary somatosensory cortex and its thalamic projection (i.e., ventral posterolateral nucleus) on the generation of electroencephalographic (EEG) responses were evaluated in healthy human volunteers. Stimulation of the unilateral somatosensory circuits corresponding to the non-dominant hand generated EEG evoked potentials across all participants; however, not all perceived stimulation-mediated tactile sensations of the hand. These FUS-evoked EEG potentials (FEP) were observed from both brain hemispheres and shared similarities with somatosensory evoked potentials (SSEP) from median nerve stimulation. Use of a 0.5 ms pulse duration (PD) sonication given at 70% duty cycle, compared to the use of 1 and 2 ms PD, elicited more distinctive FEP peak features from the hemisphere ipsilateral to sonication. Although several participants reported hearing tones associated with FUS stimulation, the observed FEP were not likely to be confounded by the auditory sensation based on a separate measurement of auditory evoked potentials (AEP) to tonal stimulation (mimicking the same repetition frequency as the FUS stimulation). Off-line changes in resting-state functional connectivity (FC) associated with thalamic stimulation revealed that the FUS stimulation enhanced connectivity in a network of sensorimotor and sensory integration areas, which lasted for at least more than an hour. Clinical neurological evaluations, EEG, and neuroanatomical MRI did not reveal any adverse or unintended effects of sonication, attesting its safety. These results suggest that FUS stimulation may induce long-term neuroplasticity in humans, indicating its neurotherapeutic potential for various neurological and neuropsychiatric conditions.

Introducing a secondary segmentation to construct a radiomics model for pulmonary tuberculosis cavities

PurposeAccurate segmentation (separating diseased portions of the lung from normal appearing lung) is a challenge in radiomic studies of non-neoplastic diseases, such as pulmonary tuberculosis (PTB). In this study, we developed a segmentation method, applicable to chest X-rays (CXR), that can eliminate the need for precise disease delineation, and that is effective for constructing radiomic models for automatic PTB cavity classification.MethodsThis retrospective study used a dataset of 266 posteroanterior CXR of patients diagnosed with laboratory confirmed PTB. The lungs were segmented using a U-net-based in-house automatic segmentation model. A secondary segmentation was developed using a sliding window, superimposed on the primary lung segmentation. Pyradiomics was used for feature extraction from every window which increased the dimensionality of the data, but this allowed us to accurately capture the spread of the features across the lung. Two separate measures (standard-deviation and variance) were used to consolidate the features. Pearson’s correlation analysis (with a 0.8 cut-off value) was then applied for dimensionality reduction followed by the construction of Random Forest radiomic models.ResultsTwo almost identical radiomic signatures consisting of 10 texture features each (9 were the same plus 1 other feature) were identified using the two separate consolidation measures. Two well performing random forest models were constructed from these signatures. The standard-deviation model (AUC = 0.9444 (95% CI, 0.8762; 0.9814)) performed marginally better than the variance model (AUC = 0.9288 (95% CI, 0.9046; 0.9843)).ConclusionThe introduction of the secondary sliding window segmentation on CXR could eliminate the need for disease delineation in pulmonary radiomic studies, and it could improve the accuracy of CXR reporting currently regaining prominence as a high-volume screening tool as the developed radiomic models correctly classify cavities from normal CXR.

The Effect of Incubator Cover on Newborn Vital Signs: The Design of Repeated Measurements in Two Separate Groups with No Control Group.

(1) Background: During their stays in neonatal intensive care units (NICU), newborns are exposed to many stimuli that disrupt their physiological indicators. The aim of this study was to investigate the impact of the light-dark cycle created with and without an incubator cover on the vital signs of term and preterm newborns. (2) Methods: A repeated measures design was used in the study utilizing two separate groups, without a control group. The study included 91 neonates hospitalized in a NICU (44 term and 47 preterm). With and without an incubator cover, the newborns' vital signs (heart rate (HR), respiratory rate (RR), oxygen saturation (SpO2), and body temperature (BT)) were measured. Three separate measurements were taken. (3) Results: The mean age of the newborns was 37.0 weeks. There was no significant difference between the HR and RR medians of the term and preterms in the incubator undraped and clad measurements (p > 0.05). At the first measurement, the SpO2 medians of the incubator-covered term and preterms were significantly higher than those of the incubator-covered term and preterms (p = 0.001). (4) Conclusions: The vital signs of the neonates demonstrated variable responses in the measurements when their incubators were covered vs. when they were not covered. However, more research on the effect of the light-dark cycle on their vital signs is required.

Features of the application of temporary access to things and documents in the process of criminal procedural evidence

In accordance with Part 2 of Art. 93 of the Criminal Procedure Code of Ukraine (hereinafter referred to as the Criminal Procedure Code), the prosecution, as a subject of evidence in a judicial investigation, obtains evidence through conducting investigative (detective) actions and covert investigative (detective) actions, requesting and receiving things, documents, information, experts' conclusions, audit conclusions and inspection reports from public authorities, local self-government bodies, enterprises, institutions and organizations, officials and individuals, as well as carrying out other procedural actions provided for by the Criminal Procedure Code of Ukraine. Other procedural actions that can be ways of obtaining evidentiary information include: filing motions, complaints, statements, objections, as well as separate measures to ensure criminal proceedings, in particular, temporary access to things and documents, temporary seizure of property, seizure of property. In this article, I would like to consider in more detail the specific features of such a procedural action as temporary access to things and documents, provided for in Chapter 15 of the Criminal Procedure Code. A system analysis of the provisions of the given chapter, other norms of the current the Criminal Procedure Code, as well as the application thereof, suggest a conclusion that there is an imperfection in the legislative regulation on the issue of applying temporary access to things and documents in the process of criminal procedural evidence.&#x0D; The publication comments on a number of norms of the Criminal Procedure Code which establish the specifics of the application of the given measure of ensuring criminal proceedings in the process of criminal procedural evidence during the pre-trial investigation, and proposes approaches to eliminating their shortcomings, based on the analysis of the specifics of the normative regulation of temporary access to things and documents. This issue is evaluated differently by both practitioners and scientists and is actively used during criminal proceedings, which is confirmed by court statistics. Theoretical and practical aspects of the given issue are considered. The article claims that despite the widespread use of the given institute, there is a significant amount of misunderstandings and contradictions between theory and practice. The paper contains critical remarks regarding the procedure of normative regulation and the use of temporary access to things and documents in the process of criminal procedural evidence. The materials of the article are both of theoretical and practical value. They can be used for further scientific research on the specifics of the application of measures to ensure criminal proceedings in the process of criminal procedural evidence, as well as for the proper understanding and implementation of law-enforcement criminal procedural activities.

Linear Classification of Neural Manifolds with Correlated Variability.

Understanding how the statistical and geometric properties of neural activity relate to performance is a key problem in theoretical neuroscience and deep learning. Here, we calculate how correlations between object representations affect the capacity, a measure of linear separability. We show that for spherical object manifolds, introducing correlations between centroids effectively pushes the spheres closer together, while introducing correlations between the axes effectively shrinks their radii, revealing a duality between correlations and geometry with respect to the problem of classification. We then apply our results to accurately estimate the capacity of deep network data.

Merging and imputation of flow cytometry data: a critical assessment.

Although most modern techniques and analysis methods in multiparameter flow cytometry (MFC) allow for increased dimensionality for the characterization and quantification of cell populations, most MFC applications depend on flow cytometers measuring relatively small (<16) numbers of parameters. When more markers than the available parameters need to be acquired, these are commonly distributed over multiple independent measurements that include a backbone of common markers. Several methods have been proposed to impute values for combinations of markers that were not measured simultaneously. These imputation methods are frequently used without proper validation and knowledge of their effects on data analysis. We evaluated the performance of existing imputation software (Infinicyt, CyTOFmerge, CytoBackBone, and cyCombine) in approximating known measured expression data in terms of similarity in visual appearance, cell expression, and gating in different datasets by splitting MFC samples into separate measurements with partially overlapping markers and re-calculating missing marker expression. Out of the assessed packages, CyTOFmerge showed the most accurate approximation of the known expression in terms of similar expression values and concordance with manual gating, with a mean F-score between 0.53-0.87 when retrieving cell populations in different datasets. Performance remained inadequate for all methods, with only limited similarity at the cell level. In conclusion, the use of imputed MFC data should take such limitations into account and include independent validation of results to justify conclusions. This article is protected by copyright.

조선인에 대한 미불금 공탁의 특례적 법령에 관한 연구

In post-war Japan under GHQ/SCAP, the policies of GHQ and the Japanese government conflicted over the handling of unpaid wages for forced labor victims from former colonies, such as Koreans. While GHQ ultimately instructed debtors, companies and business owners, to deposit them in special management accounts, etc. in order to pay outstanding payments to Koreans, the Japanese government has since 1946 decided to deposit them with each local legal bureau in accordance with the deposit procedure under the Civil Act. instructed that In general, Japanese debtor companies and others followed the instructions of the Japanese government. After 1949, when the conclusion of the Japan Peace Treaty was expected and the end of GHQ’s military rule was imminent, GHQ eventually instructed the Japanese government to devise separate measures regarding the deposit system for overseas creditors, including Koreans, unlike the existing deposit procedure under the Civil Act, as a realistic alternative. Accordingly, on February 28, 1951, ｢Prescript on Special Cases on Deposit for the Purpose of Repayment of Debts to Foreigners, etc. Living Abroad｣ (Prescript No. 22) and ｢Debt Repayment to Foreigners, etc. An Ordinance on the Enforcement of the Decree on Special Deposits (Ordinance of the Ministry of Justice, Ordinance of the Minister of Justice No. 1) was also enacted and promulgated. Since then, the Prescript on Special Cases in Deposit has been amended 8 times and the Enforcement Ordinace has been revised 9 times. This study focused on analyzing the meaning and characteristics. The main characteristics of the Prescript on Special Cases of Deposit and its Enforcement Ordinace are as follows. First, the funds of ‘foreigners residing abroad’ are specially deposited and transferred to the ‘yen account, bank of Japan’, the ‘statute of limitations’ prescribed in the existing civil law does not apply, and the right to request refund by the government delegation representing individual creditor was recongnized in the two laws. This is a very unusual special measure. In addition, it contains special provisions for deposit procedures and procedures unlike the existing civil law regulations. Second, Article 1 of the Enforcement Ordinace enumerates ‘overseas’ areas that are not included in Japan’s annexed islands, including ‘Ulleungdo, Dokdo(Take-shima), and Jejudo’. This is the one I have confirmed and reported as a thesis for the first time. Third, the main points of the revised contents of the two laws are the deletion of GHQ’s deposit order and procedures, the deletion of the clause on the right to claim refund by the government delegation representing individual victims, and the inclusion of clause Dokdo etc., as annexed islands of Japan. It is the point that the clause about overseas regions was deleted. Overall, the above content restricts the deposit procedure for unpaid money for Korean victims of forced labor, lowers the possibility of claiming the deposit, and restricts the procedure, and can be regarded as an amendment to delete provisions unfavorable to the claim to sovereignty over Dokdo.

The Effects of Specialized Grip Strength Training on Hand-Grip Performance of Male Wrestlers Aged 13-17

The purpose of this research was to examine the effect of special grip strength-improving training on the performance of male wrestlers aged 13 – 17 years. The research sample consisted of 40 athletes the Wrestling Training Center in the district of Kavak in the province of Samsun, Türkiye. In addition to the annual training plan, the athletes in the experimental group underwent a special grip strength improving application consisting of five separate measures on a regular basis for eight weeks. The control group continued with their activities in line with the Wrestling Training Center annual training plan. Differences in grip strength in the groups were determined using Student’s t test, while relationships between participants’ ages, years spent in sport, height, weight, and grip strength (improvement values) were determined using Pearson’s correlation coefficient. SPSS version 22.0 software was used for all statistical calculations. The eight-week special grip strength training produced a statistically significant improvement (difference measurements) in the athletes’ right (P&amp;lt;0.001) and left hands (P=0.004). The special grip strength-improving training measures applied for eight weeks improved grip strength, an important ability for success in the sport of wrestling.
