Purpose
The aim of this study was to assess the reliability and validity of the My Jump 2® app in measuring jump height, flight time, and peak power among elite women beach volleyball players on sand surfaces.

Methods
Eleven elite female beach volleyball players (aged 23.6 ± 6.2 years; weight 66.3 ± 5.8 kg; height 174.4 ± 5.8 cm; with 8.4 ± 4.8 years of professional experience) participated in this study. Each player performed six countermovement jumps in a wooden box filled with sand on a force platform while simultaneously recording a video for subsequent analysis using the My Jump 2® app.

Results
We found excellent agreement for flight time, jump height and peak power between observers (ICC = 0.92, 0.91 and 0.97, respectively). No significant differences between force platform and My Jump 2® app were detected in the values obtained for the three variables (P > 0.05). For the force platform and the My Jump 2® app, we found a good agreement measuring jump height and flight time (ICC = 0.85 and 0.85, respectively). However, we only found a moderate agreement for peak power (ICC = 0.64). The difference in jump height showed a limit of agreement between −4.10 and 4.74 cm in Bland-Altman, indicating a high level of agreement between the two measurement tools.

Conclusion
Based on our findings, the My Jump 2® app reveals a valid tool for measuring jump height and flight time of CMJ on sand surfaces. However, more caution is needed when measuring peak power.

Authors: A.S. Saranya , Mathew Lea , K Swarnalatha , A Sheela 
Published: May 2024

Aim: The present study analysed the presence of antimicrobial resistance organisms and genes in the final effluent from STPs of hospitals.
Study Area and Sampling: Samples for microbiological analysis were collected from two different hospitals in Trivandrum City and carried out further microbiological analysis.
Methodology: In this study, MDRB (Multi Drug Resiatant Bacteria) were detected from the hospital effluent samples collected from two hospitals. Antibiotic susceptibility analysis showed that the 90% screened organisms was resistant to different antibiotics -Tetracycline (30µg), Amikacin (30µg), Gentamycin (10µg), Ciprofloxacin (5µg), Colistin (10µg) and Amoxicillin (30µg)). Metagenomic surveillance of effluent helped to assess the efficacy of STPs, at the same time assessing the local clinical antibiotic resistance condition by detection of the presence of antimicrobial resistance towards antibiotics and their genes (ARGs) in the hospital effluent.
Results: In this study, a total of 3 antibiotic resistant bacterial strains obtained from hospital STP effluent were identified by16S rRNA sequence analysis. The sequences of E.coli, Klebsiella and Enterobacter were submitted in Genbank with accession number MT784125, OM978270 andMN437586 respectively.The final effluent from Hospital 1 showed100% resistance to Tetracycline and 86% resistance to Amoxicillin followed by sensitivity 28%, 22%, 18% and 10% respectively to Ciprofloxacin, Gentamycin, Amikacin and Colistin. The bacterial strains isolated from final effluent of Hospital 2 showed highest resistance to Amikacin and Colistin which is 100% and 86% and 82% resistance to Gentamycin and Ciprofloxacin. The gene primers used for the respective genes above have been amplified in the sample with a higher efficiency of 16 SrRNA, ermB and ampC primers showing a lower Cq value. Thus, these three genes were detected in the samples at high amount which showed the prominent use of the consecutive antibiotics in the clinical field
Estimation Involving a Class of Special Arithmetical Functions
Authors: Yu Tingwei 
Published: May 2024

The mean value estimation of arithmetical function is closely related to many problems in number theory. Let f be an arithmetical function satisfying some conditions. Let [r] be the integral part of r. This paper proves that the asymptotic expression $$S_f(y):=\sum_{n \leq y} f([y / n]) /\left([y / n]^{k-1}\right)\left(k \in \mathbb{N}^{+}\right)$$ and the error term of this asymptotic formula is \(\Omega\)(y). The arithmetical function in this paper satisfies certain conditions, and the Dirichlet hyperbolic principle is used in the proof of the conclusion. With the different values of the independent variable of the function, the function value of the arithmetical function is often irregular, and the property of the mean value of the arithmetical function is more regular than that of the arithmetical function itself. Therefore, with the help of the mean value estimation results of the arithmetical function, we can have a deeper understanding of the nature of the arithmetical function itself, and then provide ideas for solving more problems.

AbstractOur aim was to develop an age‐appropriate measure of early manifestations of aggression. We constructed a questionnaire about normative developmental milestones into which a set of items measuring infants' use of physical force against people and expressed anger were included. These items comprise the Cardiff Infant Contentiousness Scale (CICS). Evidence for the reliability and validity of the CICS is provided from analyses of a sample of N=310 British infants, assessed at a mean age of 6 months as part of a larger longitudinal study of the development of aggression. The informants' CICS ratings demonstrated reasonable levels of internal consistency and interrater agreement. Informants' ratings were validated by observations of infants' distress in response to restraint in a car seat. Longitudinal analyses revealed that contentiousness was stable over time and that contentiousness at 6 months predicted infants' later use of force with peers. When used in the company of other methods, the simple four‐item CICS scale could serve as a useful screen for early manifestations of aggressiveness in human infants. Aggr.

Bulk Metallic Glass: The Smaller the Better
Authors: Kumar Golden , Desai Amish , Schroers Jan 
Published: October 2010

AbstractBulk metallic glasses (BMGs) are strong, highly elastic, and resistant to wear but still find limited utility due to their macroscopic brittle nature, high costs, and difficulty of processing, particularly when complex shapes are desired. These drawbacks can be mitigated when BMGs are used in miniature parts (< 1 cm), an application which takes advantage of BMGs' enhanced plasticity at small length scales as well the insignificant material cost associated with such parts. As an alternative to traditional metal processing techniques, thermoplastic forming (TPF)‐based microfabrication methods have been developed which can process some BMGs like plastics. In this article, we discuss the properties and fabrication of BMGs on minuscule length scales to explore their prospective application in small‐scale devices.
Enzyme Mimics Based Upon Supramolecular Coordination Chemistry
Authors: Wiester Michael J. , Ulmann Pirmin A. , Mirkin Chad A. 
Published: October 2010

AbstractRecent advances in supramolecular coordination chemistry have allowed chemists to synthesize macromolecular complexes that exhibit various properties intrinsic to enzymes. This Review focuses on structures inspired by properties and functions observed in enzymes rather than precise models of enzyme active sites. These structures are synthesized using convergent, modular, and high‐yielding coordination‐chemistry‐based methods, which allow one to tailor the size, shape, and properties of the resulting complexes. Many of the structures discussed exhibit reactivity and specificity reminiscent of natural systems, and some of them have functions that exceed the natural systems which provided the inspiration for initially making them.
Poisoning Experiments Aimed at Discriminating Active and Less‐Active Sites of Silica‐Supported Tantalum Hydride for Alkane Metathesis
Authors: Saggio Guillaume , Taoufik Mostafa , Basset Jean‐Marie , Thivolle‐Cazat Jean 
Published: October 2010

AbstractOnly 50 % of the silica‐supported tantalum hydride sites are active in the metathesis of propane. Indeed, more than 45 % of the tantalum hydride can be eliminated by a selective oxygen poisoning of inactive sites with no significant decrease in the global turnover. Conversely, cyclopentane induces no such selective poisoning. Hence, the active tantalum hydride sites that show greater resistance to oxygen poisoning correspond to the νTaH bands of higher wavenumbers, particularly that at 1860 cm−1. These active tantalum hydride sites should correspond to tris‐ or monohydride species relatively far from silica surface oxygen atoms.
Catalytic Hydrogenation Using Abnormal N‐Heterocyclic Carbene Palladium Complexes: Catalytic Scope and Mechanistic Insights

Published: October 2010

AbstractPalladium complexes containing abnormally bound C4‐bound dicarbene ligands have been exploited for catalytic alkene hydrogenation. Comparison to normally C2‐bound homologues indicates that the carbene bonding mode critically influences the catalytic activity. Good catalytic performance in the hydrogenation of cis‐disubstituted olefins and non‐isomerizable terminal olefins under mild conditions (RT, 0.1 MPa H2) only occurs when the carbene is abnormally bound to the palladium center. Detailed mechanistic investigations using dynamic light scattering in connection with time‐dependent analysis of conversions, and also performance of substoichiometric catalytic experiments provide evidence that the catalysis is heterogeneous and that the abnormally bound carbene ligand has the role of an activator.
Synthesis and Structural Aspects of N‐Triflylphosphoramides and Their Calcium Salts—Highly Acidic and Effective Brønsted Acids
Authors: Rueping Magnus , Nachtsheim Boris J. , Koenigs René M. , Ieawsuwan Winai 
Published: October 2010

AbstractRecently, 1,1′‐bi‐2‐naphthol (BINOL)‐based N‐triflylphosphoramides emerged as a new class of potent Brønsted acid catalysts. In this paper we describe the efficient synthesis of various BINOL‐based N‐triflylphosphoramides and their calcium salts. Furthermore, X‐ray crystal structure analysis combined with energy‐dispersive X‐ray spectroscopy (EDX) measurements confirmed that the synthesised chiral N‐triflylphosphoramides are highly acidic metal‐free catalysts.
Consequences of the halloween nightmare: analysis of investors&otilde; response to an overnight tax legislation change in the canadian income trust sector
Authors: Glew Ian A. , Johnson Lewis D. 
Published: October 2010

AbstractOn October 31, 2006, the Canadian federal government announced increased taxation of income trusts, beginning in 2011. Using discounted cash flow analysis, we investigated timing of the market adjustment. Energy, utility, and business trust prices dropped by predicted amounts, indicating a rational market response. Following the announcement, however, affected sectors reacted differently: Energy and utility trusts were more likely to merge within their sectors while business trusts became private equity targets. The income trust case is a classic example of a natural event, and our results underscore the efficiency of Canadian capital markets. Copyright © 2010 ASAC. Published by John Wiley & Sons, Ltd.
Relationship between positive psychological capital and creative performance
Authors: Sweetman David , Luthans Fred , Avey James B. , Luthans Brett C. 
Published: October 2010

AbstractDespite considerable attention to the creative process and its relationship with personal characteristics, there is no published study focused directly on the relationship between the recently recognized core construct of psychological capital (PsyCap) and creative performance. Drawing from a large (N = 899) and heterogeneous sample of working adults, this study investigates PsyCap and its components (i.e., efficacy, hope, optimism, and resilience) as predictors of creative performance. Overall PsyCap predicted creative performance over and above each of the four PsyCap components. Theoretical and practical implications of these findings are considered. Copyright © 2010 ASAC.

Published: October 2010

AbstractBACKGROUND:Osteosarcoma survivors have received significant chemotherapy and have undergone substantial surgeries. Their very long‐term outcomes (20 year) are reported here.METHODS:The authors assessed the long‐term outcomes of 733 5‐year survivors of childhood osteosarcoma diagnosed from 1970 to 1986 to provide a comprehensive evaluation of medical and psychosocial outcomes for survivors enrolled in the Childhood Cancer Survivor Study (CCSS). Outcomes evaluated included overall survival, second malignant neoplasms (SMNs), recurrent osteosarcoma, chronic health conditions, health status (general and mental health and functional limitations), and psychosocial factors. Outcomes of osteosarcoma survivors were compared with general‐population statistics, other CCSS survivors, and CCSS siblings.RESULTS:Survivors had a mean follow‐up of 21.6 years. The overall survival of children diagnosed with osteosarcoma who survived 5 years at 20 years from original diagnosis was 88.6% (95% confidence interval [CI], 86.6%‐90.5%). The cumulative incidence of SMNs at 25 years was 5.4%, with a standardized incidence ratio of 4.79 (95% CI, 3.54‐6.33; P<.01). Overall, 86.9% of osteosarcoma survivors experienced at least 1 chronic medical condition, and >50% experienced ≥2 conditions. Compared with survivors of other cancers, osteosarcoma survivors did not differ in their reported general health status (odds ratio [OR], 0.9; 95% CI, 0.7‐1.2), but were more likely to report an adverse health status in at least 1 domain (OR, 1.9; 95% CI, 1.6‐2.2), with activity limitations (29.1%) being the most common.CONCLUSIONS:Childhood osteosarcoma survivors in this cohort did relatively well, considering their extensive treatment, but are at risk of experiencing chronic medical conditions and adverse health status. Survivors warrant life‐long follow‐up. Cancer 2011. © 2010 American Cancer Society.
Gemcitabine and docetaxel in metastatic, castrate‐resistant prostate cancer
Authors: Garcia Jorge A. , Hutson Thomas E. , Shepard Dale , Elson Paul , Dreicer Robert 
Published: October 2010

AbstractBACKGROUND:Docetaxel is the standard of care for patients with metastatic, castrate‐resistant prostate cancer (CRPC). Gemcitabine is a nucleoside analogue with broad antitumor activity. In a phase 2 study of combined docetaxel and gemcitabine, the authors assessed its safety and activity in patients with chemotherapy‐naive, metastatic CRPC.METHODS:Eligible patients had untreated, metastatic CRPC with radiologic and/or biochemical evidence of progression after antiandrogen withdrawal with castrate testosterone levels, an Eastern Cooperative Oncology performance status (ECOG PS) of 0 to 2, and adequate organ function; no previous chemotherapy was permitted. Patients received gemcitabine (800 mg/m2) Days 1 and 8 and docetaxel (75 mg/m2) on Day 8 every 21 days for a maximum of 6 cycles. Response was evaluated using Response Evaluation Criteria in Solid Tumors (RECIST) for measurable disease. A prostate‐specific antigen (PSA) response was defined as a decline ≥50% in baseline PSA level.RESULTS:Thirty‐five patients with chemotherapy‐naive, metastatic CRPC were enrolled. The median age was 67 years, and 60% of patients had an ECOG PS of 0. PSA responses were observed in 49% of patients. Among the patients who had measurable disease (n = 25), 3 patients (12%) had a confirmed, RECIST‐defined partial response (PR); 4 patients (16%) had an unconfirmed PR; and 15 patients (60%) achieved stable disease. The most common adverse events included grade 1 and 2 fatigue (69%), alopecia (80%), and nausea/vomiting (54%). No treatment‐related deaths were noted, but an unusually high incidence of grade 3 and 4 neutropenia was observed.CONCLUSIONS:The efficacy of combined gemcitabine and docetaxel in metastatic CRPC was similar to that observed with single‐agent docetaxel. In contrast to single‐agent docetaxel, the combination was moderately toxic and had an impact primarily on bone marrow reserve. Cancer 2011. © 2010 American Cancer Society.

Published: October 2010

AbstractBACKGROUND:Patient satisfaction is an important outcome measure of quality of cancer care and 1 of the 4 core study outcomes of the National Cancer Institute (NCI)‐sponsored Patient Navigation Research Program to reduce race/ethnicity‐based disparities in cancer care. There is no existing patient satisfaction measure that spans the spectrum of cancer‐related care. The objective of this study was to develop a Patient Satisfaction With Cancer Care measure that is relevant to patients receiving diagnostic/therapeutic cancer‐related care.METHODS:The authors developed a conceptual framework, an operational definition of Patient Satisfaction With Cancer Care, and an item pool based on literature review, expert feedback, group discussion, and consensus. The 35‐item Patient Satisfaction With Cancer Care measure was administered to 891 participants from the multisite NCI‐sponsored Patient Navigation Research Program. Principal components analysis (PCA) was conducted for latent structure analysis. Internal consistency was assessed using Cronbach coefficient alpha (α). Divergent analysis was performed using correlation analyses between the Patient Satisfaction With Cancer Care, the Communication and Attitudinal Self‐Efficacy–Cancer, and demographic variables.RESULTS:The PCA revealed a 1‐dimensional measure with items forming a coherent set explaining 62% of the variance in patient satisfaction. Reliability assessment revealed high internal consistency (α ranging from 0.95 to 0.96). The Patient Satisfaction With Cancer Care demonstrated good face validity, convergent validity, and divergent validity, as indicated by moderate correlations with subscales of the Communication and Attitudinal Self‐Efficacy–Cancer (all P < .01) and nonsignificant correlations with age, primary language, marital status, and scores on the Rapid Estimate of Adult Literacy in Medicine Long Form (all P > .05).CONCLUSIONS:The Patient Satisfaction With Cancer Care is a valid tool for assessing satisfaction with cancer‐related care for this sample.

Intolerance to tyrosine kinase inhibitors in chronic myeloid leukemia
Authors: Pinilla‐Ibarz Javier , Cortes Jorge , Mauro Michael J. 
Published: October 2010

AbstractTyrosine kinase inhibitor (TKI) treatment targeting breakpoint cluster region‐Abelson murine leukemia virus, the cause of chronic myeloid leukemia (CML), has revolutionized therapy for patients with this disease. The majority of patients with CML maintain favorable responses with long‐term imatinib therapy; however, the availability of the second‐generation TKIs nilotinib and dasatinib limits the need for patients intolerant to imatinib to continue with therapy. Unfortunately, there is currently no standard definition of intolerance to imatinib. Common Toxicity Criteria for grading adverse events, designed to identify acute toxicities, are often used to determine intolerance. However, because CML therapies are long‐term, patient quality of life may provide a better measure of true intolerance. Several general methods of quantifying patient quality of life are in use for patients with CML, and a CML‐specific variant of the M. D. Anderson Symptom Inventory is in development. An appropriate and consistent definition of intolerance will provide clinicians with an algorithm for managing their patients with severe or chronic adverse events during treatment with imatinib. As more long‐term data become available for newer TKIs, the definition of intolerance in the context of CML treatment will continue to evolve to maximize the likelihood of durable responses and superior quality of life for patients.

Single‐Molecule Fluorescence Coincidence Spectroscopy and its Application to Resonance Energy Transfer
Authors: Orte Angel , Clarke Richard W. , Klenerman David 
Published: October 2010

AbstractThe use of Förster resonance energy transfer (FRET) as a tool to study biomolecules has been greatly enhanced by new advances in single‐molecule fluorescence (SMF) techniques. This has allowed new insights into the structure and dynamics of complex biomolecular machinery. However, there are still technical drawbacks in the application of conventional SMF–FRET. Herein, we review the use of single‐molecule coincidence spectroscopy to study FRET systems, an analytical variation of the conventional scheme, using one or two confocal lasers of different colours. We highlight the advantages of the coincidence spectroscopy and illustrate this with examples of its application to some biological systems of interest.

Published: October 2010

AbstractVanadium oxide nanorods were prepared by a hydrothermal route and then tested as a transducer for a resistive‐type gas sensor. The importance of control of pH and pressure during the synthesis of 1D crystals of vanadium oxide was demonstrated for the V2O5/ethanol mixture, which served as a precursor. As a gas sensor element, the nanorods demonstrated a stable response to triethylamine and weak sensor response to carbon monoxide with a short response time (as low as 32 s).

AbstractThe sandwich lanthanide(III) complexes BnO,BuPc2Ln (BnO,BuPc = 2‐benzyloxy‐9,10,16,17,23,24‐hexa‐n‐butylphthalocyaninate; Ln = Eu, Lu) (1a, 1b) were obtained from [Ln(acac)3]·nH2O and BnO,BuPcH2 by heating these compounds in n‐hexadecanol, and then treating the reaction solution with H2SO4 to yield the corresponding neutral double‐decker complexes HO,BuPc2Ln (HO,BuPc = 9,10,16,17,23,24‐hexa‐n‐butyl‐2‐hydroxyphthalocyaninate) (2a, 2b), which are promising structural building blocks and stable phenolic hydroxy group containing π‐radical species. A combination of UV/Vis/NIR, NMR spectroscopy, MALDI‐TOF mass spectrometry, cyclic voltammetry and spectroelectrochemistry provided unambiguous characterization of the newly prepared bis(phthalocyanines), and also allowed their stability and behavior in solution to be investigated.
