Intra-rater and Inter-rater Reliability of the KangaTech (KT360) Fixed Frame Dynamometry System During Maximal Isometric Strength Measurements of the Knee Flexors.
Authors: Woolhead Ellie , Partner Richard , Parsley Megan , Jones Ashley 
Published: November 2024

Background Fixed-frame dynamometry systems are used worldwide to assess isometric strength in both general and athletic populations. There is currently a paucity of published work where reliability estimates for fixed-frame dynamometry systems have been estimated. The aim of this study was to determine the inter-and intra-rater reliability of the KangaTech (KT360) fixed frame dynamometry system when measuring maximal isometric strength of the knee flexor muscles. Study Design Inter and intra-rater reliability single cohort study. Methods Twenty healthy university-level athletes (age= 21.65 ± 3 years, weight= 74.465 ± 30kg, height= 170.1 ± 7.0cm) took part in two testing sessions where two raters collected data during a 90° hip and knee flexion protocol. Participants performed each test twice, building to a maximal isometric contraction holding over a 5 second period with 30 second rest between sets. Data were checked for normality using a Shapiro-Wilk test. Intraclass correlation coefficient (ICC), standard error of measurement (SEM) and minimal detectable change (MDC) were calculated. Finally, a Bland-Altman analysis was used to determine the levels of agreement for intra-and inter-rater measurements. Results High levels of agreement were demonstrated between left and right knee flexion as 95% of the differences were less than two standard deviations away from the mean. ‘Almost perfect’ intraclass correlation coefficient (ICC) values were demonstrated (Knee flexion: Inter-rater: Left, 0.99; Right, 0.99; Intra-rater: Left, 0.99; Right:0.99). Standard error of measurement (SEM) for inter-and intra-rater strength ranged from 0.26-0.69 kg, SEM% ranged from 1.34-2.71% and minimal detectable change (MDC) ranged from 1.14-2.31kg. Conclusion Overall, high level of inter-and intra-rater reliability were demonstrated when testing maximal isometric knee flexion. Therefore, the KT360 fixed frame dynamometry system may be considered a viable tool for measuring maximal isometric contraction of the knee flexors when repeat measures are required in clinical settings.

Apuntes sobre los mecanismos de acceso a la representación política para grupos en situación de vulnerabilidad en los procesos electorales de 2021 y 2024
Authors: Huerta-Alderete Aldo 
Published: November 2024

El proceso electoral 2023-2024 tuvo un carácter excepcional por una multiplicidad de factores. La consolidación de la hegemonía de un partido en la Cámara de Diputados, el Senado de la República, congresos locales, gubernaturas y ayuntamientos cambió sustancialmente el mapa electoral. Sin embargo, un elemento clave que pasa desapercibido es la postulación de personas adscritas a grupos históricamente excluidos: indígenas, afromexicanas, personas con discapacidad, con orientación sexual e identidad de género (OSIG) no normativas.

Published: November 2024

The application of Freire's thinking in the context of elementary education can be seen through a dialogical and critical approach in teaching. Teachers not only convey knowledge, but also act as facilitators who help students to think critically and be actively involved in the learning process. The type of research used in this study is library research . Data sources in this library research consist of two categories: 1). Primary Data Sources: The main books written by Paulo Freire, especially Pedagogy of the Oppressed (1970). 2). Secondary Data Sources: Scientific articles, journals and research reports that discuss the application of Freire's thinking in elementary education. The results of the study show that 1). Critical Conscientization in Elementary Education is a process in which individuals understand the social and political injustices around them. 2). Dialogical Education in Elementary Education is a key element in education, where teachers and students learn from each other through two-way communication. 3). Humanistic and Inclusive Education in Elementary Education is where every student is valued as an individual who has the potential to develop, without discrimination based on social and economic background. 4). Implications for Basic Education in Indonesia are that the recently introduced independent curriculum gives teachers and students more freedom to explore subject matter flexibly, in accordance with the principles of liberating and dialogical education as taught by Freire

The pyrometallurgical extraction of platinum from an oxide system based on SiO2, Al2O3 and CaO has been experimentally studied. This material was an unclaimed waste of the glass industry with a platinum content of 0.03 %. The material was subjected to reduction melting in a laboratory DC ore-thermal furnace. The furnace had a graphite crucible with a volume of 10 dm3 with an axially mounted graphite electrode. The crucible had a magnesite lining and was placed in a steel casing. A negative potential was applied to the electrode from the power supply, and a positive potential was applied to the crucible. The melting was carried out at a current of 300 A and a voltage of 100 V. The material was loaded during the melting process as it melted. A flux based on CaO and SiO2 was added to the material to reduce the melting point. The melt had a temperature of 1850 K in this case. 41.6 kg of the charge was remelted for 6.5 hours with an intermediate drain of the melt. The melt was drained partly by tilting the crucible, leaving the metal phase at the bottom. The metal phase weighed 322 g. It was ferrosilicon containing ≈ 20 % Si and 1.44 % Pt. The energy and material balances of melting were considered. The microstructure of both the initial material and the products of melting were studied. Platinum is contained in the starting material in the form of inclusions with a size of about 10 mm. The inclusions were deposited on the bottom of the crucible when the material was melted and were extracted with ferrosilicon, formed as a result of carbon thermal reduction. It was shown that the Stokes law is applicable to determine the deposition rate under electric melting conditions. Platinum and copper form separate phases when ferrosilicon solidifies. The platinum content is about 50 % in these phases.

Published: November 2024

One of the promising technological processes aimed at expanding the scope of application of deformable heat-treated high-strength aluminum-based alloys such as D16, B95, etc. is liquid stamping — crystallization under pressure. In the process of liquid stamping, defects of gas-shrinkage origin and liquation occur in sections with a thickness of more than 40 mm, which cannot be eliminated by known methods. As an approach to solving this problem, it is proposed to use the dependence of the change in the volume of the crystallizing metal on the pressure value. It is established that the metal property hidden from the known methods of studying the crystallization process, referred to in this work by the term “compactness of the crystallizing metal” can be up to 5 – 6 % of the total volume of the metal. An original research methodology is proposed, controlled and controlled process parameters are determined to ensure the formation of a structure without defects. Using the example of the production of molds for casting plastic parts, the advantages of the proposed casting process with the imposition of pressure on the crystallizing metal are shown.
Ab initio investigation of structural, elastic, dynamic, and electronic properties of YN binary rare earth nitride in ZB cubic phase
Authors: Kadri Asma , Sediki Hayet , Hiadsi Said , Elchikh Mokhtar 
Published: November 2024

This research employs ab initio calculations, utilizing the FP-LAPW method as implemented in WIEN2k and the PP-PW method in QUANTUM ESPRESSO, within the framework of the GGA-PBE approximation, to investigate the physical properties of the rare earth nitride binary YN. Structural parameters of YN are determined, yielding predictive results consistent with recent calculations. Furthermore, a comprehensive investigation into mechanical behavior and elastic properties confirms the mechanical stability of YN in its cubic ZB structure. An analysis of the anisotropy coefficient reveals its elastic anisotropy. The dynamic stability of YN is investigated through PW-scf calculations using DFPT theory, enabling the calculation of phonon spectra, frequencies, and polarization vectors. These findings affirm the stability of YN material in the B3 structure, which can be experimentally synthesized. Electronic properties are probed, showing semiconductor behavior, utilizing GGA mBJ, and YS PBE0 methods to ascertain band gap values in the B3 structure. This suggests its potential for adoption in optoelectronic and photonic devices.

Published: November 2024

In this study, our goal is to analyze the origin of magnetization in non magnetic cubic structure perovskite BaSnO3 doped with 2p-X (X=C, N) using the full potential linearized augmented plane wave (FP-LAPW) method based on density functional theory (DFT). For the exchange and correlation potential we have applied the generalized gradient approximation (GGA) and the GGA plus-modified Becke-Johnson potential (mBJ-GGA). The results show that BaSnO3 doped with C then with N and finally with C and N exhibit half-metallic ferromagnetism behavior with the integer magnetic moment of 1, 2 and 3 μB per cell respectively. The origin of the ferromagnetism that occurs within these compounds is mainly caused by the p-p hybridization between 2p-impurities and its neighboring oxygen atoms. These results allowed to conclude that doped perovskite could provide a new type of materials, called half-metallic for future spintronic devices.

Published: November 2024

OBJECTIVE
Radiation necrosis (RN) is a well-recognized late complication most commonly occurring within 2 years of stereotactic radiosurgery (SRS); however, late RN (LRN), RN occurring or recurring > 5 years after SRS, has been poorly described. This study analyzes the incidence of and risk factors for LRN occurring > 5 years after SRS.

METHODS
This retrospective analysis included patients treated with linear accelerator–based SRS for tumors or arteriovenous malformations with > 5 years of clinical and serial MRI follow-up. LRN was defined as new neurological symptoms with neuroanatomically correlated imaging findings without disease recurrence. Univariate and multivariate analyses for LRN were performed using the Cox proportional hazards model.

RESULTS
The authors identified a cumulative 297 lesions in 219 patients treated to a median dose of 17 Gy with a median follow-up of 7.4 years. In total, 290 (97.6%) lesions were treated in a single fraction, and 64 (21.5%) were treated after resection. The LRN occurred in 19 (8.7%) patients and in 23 (7.7%) lesions at a median of 6.1 years (range 5.1–13.9 years) after SRS. Fifteen of the 23 (65.2%) lesions were managed with steroids, bevacizumab, and/or antiepileptic drugs. The remaining 8 (34.8%) were resected; histopathology confirmed necrosis without disease recurrence in each. On multivariate analysis, only > 5-cm3 volume of the brain receiving 12 Gy (brain V12Gy) (HR 6.01, 95% CI 1.77–20.48; p = 0.004) and a history of early, previously resolved RN (HR 9.53, 95% CI 2.00–45.61; p = 0.005) remained significantly associated with LRN.

CONCLUSIONS
RN risk persists well beyond 5 years after SRS, and recognizing LRN as an entity has important implications in managing these patients. LRN risk was highest in those with a brain V12Gy > 5 cm3 and a history of early RN after SRS, warranting close follow-up in perpetuity for select patients.

OBJECTIVE
Spinal cord ischemia (SCI) remains one of the most devastating complications in both open and endovascular stent graft repair of thoracoabdominal aortic aneurysms. The endovascular aortic aneurysm repair (EVAR) can be either thoracic (TEVAR) when it targets the thoracic aortic aneurysm or fenestrated branched when repair involves the visceral and/or renal arteries. Even though EVAR interventions are less invasive than open repair, they are still associated with a significant risk of SCI. The current primary strategy to prevent SCI after TEVAR is to increase and/or maintain spinal cord perfusion pressure (blood flow) by increasing the mean arterial pressure while simultaneously draining CSF. Although the benefit of CSF drainage in EVAR procedures remains uncertain, it provides an opportunity to study the changes in cytokine and oxidative stress markers that may signal the pathophysiology of SCI following EVAR. The aim of this study was to evaluate the temporal relationship between stent deployment and CSF cytokine and oxidative stress marker levels as predictors of delayed SCI in patients undergoing an EVAR procedure.

METHODS
There were 16 EVAR cases across 15 patients enrolled in this study, with 1 patient undergoing the procedure twice 1 year apart. The levels of oxidative stress (8-hydroxy-2′-deoxyguanosine [8-OHdG], glial fibrillary acidic [GFAP], and lactic acid) and proinflammatory (tumor necrosis factor–alpha [TNF-α], interleukin (IL)–6, and IL-1β) and antiinflammatory (IL-4) markers were quantified at different time points between 0 and 48 hours after EVAR by enzyme-linked immunosorbent assay. The changes in protein levels of both oxidative stress and inflammatory markers were expressed as fold change from the time of the lumbar drain insertion prior to surgery.

RESULTS
Following the EVAR procedure, 8-OHdG resulted in the highest upregulation at later time points postoperatively (48 hours) and this increase was positively correlated with TNF-α level. The data also revealed that IL-6 peaked during the stent deployment intervention and this pattern of expression was positively correlated with the expression of lactic acid. No significant changes were noted in the expression levels of GFAP, lactic acid, and IL-1β.

CONCLUSIONS
There appears to be a temporal relationship between lumbar CSF drainage and CSF cytokines and oxidative stress markers that may help 1) identify patients at risk for developing delayed SCI and 2) modify patient management to prevent the damage from delayed SCI.

OBJECTIVE
Wound dehiscence following craniotomy is a complication for which patients are subjected to additional procedures to achieve wound closure. During surgery for epilepsy, a craniotomy is performed at various sites to cure or palliate seizures in patients with intractable epilepsy. Collaborations between medicine and engineering have provided many surgical devices and materials for various stages of craniotomy, from skin incision to wound closure. The risk factors for wound dehiscence remain undetermined. Here, the authors attempt to identify risk factors associated with wound dehiscence after surgery for epilepsy.

METHODS
They retrospectively reviewed the clinical records and operative notes of consecutive patients with intractable epilepsy who had undergone craniotomy to allow resective or disconnective surgery between 2015 and 2023 in the Department of Neurosurgery, Hiroshima University Hospital, and had a minimum follow-up of 1 year. The authors conducted a multivariate logistic regression analysis to determine the risk factors for wound dehiscence.

RESULTS
The study population comprised 174 patients who had undergone corpus callosotomy (70 patients), cortical resection (CR; 65 patients), or CR via intracranial video electroencephalography monitoring (IVEEG; 39 patients). Wound dehiscence occurred in 14 patients (8.0%). Univariate analysis showed that wound dehiscence was associated with CR via IVEEG (p = 0.0330), electrocautery scalpels (p = 0.0037), T-shaped skin incisions (p = 0.0216), dural closure (p = 0.0002), and longer operative duration (p = 0.0088). Multivariate logistic regression analysis revealed that skin incision using an electrocautery scalpel (p = 0.0462, OR 9.38, 95% CI 1.04–84.74) and dural closure using nonabsorbable artificial dura (p = 0.0078, OR 6.29, 95% CI 1.63–24.31) were independent risk factors for wound dehiscence.

CONCLUSIONS
Surgical devices and materials contribute to wound dehiscence after epilepsy surgery. To avoid wound dehiscence, the use of an electrocautery scalpel is not recommended when performing skin incisions, nor is dural closure using a nonabsorbable artificial dura.
