This study aimed to ascertain the impact of oocyte harvest methods and storage times on the amount, quality, and rate of buffalo oocyte maturation in vitro. Ovaries were collected from slaughterhouse at four different time storages (0, 3, 6, 9 and 12 h) before processing with three collection techniques slicing, aspiration, and slicing plus the aspiration of oocytes. According to the morphology of cumulus cell layers closely attached to the zona pellucida of the oocytes and the cytoplasmic appearance of the oocytes, the oocytes were divided into 4 groups (A, B, C, and D). Cumulus-oocyte-complexes (COCs) were transferred into in vitro maturation (IVM) medium of TCM- 199 (Sigma) for 24 h. The stages of nuclear maturation were examined by staining the enlarged COCs from each group. The result found that the average quantity of oocytes per ovary ranged from 8.08±1.28 to 9.83 ±1.89 and no significant effect (P0.05) on the quantity of oocytes per ovary. The average of oocytes quality per ovary ranges from 0.2 to 5.00 was a highly significant effect of storage time on quality oocytes (P0.01). The maturation rate in the M-II stage ranges from 1.33 to 3.92 per ovary, and storage time is a significant effect (P0.05) on the maturation rate of local buffalo. The collection methods were highly significant (P0.01) on the quantity of oocytes between slicing and aspiration, also between aspiration plus slicing, and no significant (P0.05) between slicing and aspiration plus slicing. The Average oocyte quality ranged from 0.10 to 4.95 per ovary and the highest in slicing plus aspiration methods (P0.05). The average maturation rate in M-II stage was ranged from 1.00 to 3.85 oocytes per ovary, and the methods of oocytes collection were significant (P0.05) on the maturation rate of local buffalo. In conclusion that the storage time of up to 6 h and aspiration plus slicing is suitable on in vitro maturation of local buffalo.

Idiosyncratic entrenchment: tracing change in constructional schematicity with nested random effects
Authors: Vetchinnikova Svetlana 
Published: August 2024

Abstract
Usage-based constructionist approaches see language as an inventory of constructions at different levels of schematicity learned from the input. If so, personal constructicons should vary as a function of usage. Repeated use and chunking/entrenchment of concrete instances should lead to reanalysis of their internal structure and change in the level of schematicity. This paper exploits the reduction probability of is in it is as a diagnostic of reanalysis in a 1.75-million-word diachronic corpus of a single blogger over 8 years. All instances of it is/it’s (n = 10,929) were annotated at the constructional and lexical levels. A multilevel logistic regression model showed significant fixed effects of constructional entropy and construction-to-word association on reduction probability. Importantly, there remained substantial variation across lexical types of constructions in the extent to which they associated or became associated with reduction over time, suggesting idiosyncratic entrenchment and potential reanalysis as a function of usage.

Abstract
We study semicontinuous maps on varieties of modules over finite-dimensional algebras.
We prove that truncated Euler maps are upper or lower semicontinuous.
This implies that 𝑔-vectors and 𝐸-invariants of modules are upper semicontinuous.
We also discuss inequalities of generic values of some upper semicontinuous maps.
Highly photocatalytic materials based on the decoration of poly(O-chloroaniline) with molybdenum trichalcogenide oxide for green hydrogen generation from Red Sea water
Authors: Aldosari Eman , Rabia Mohamed , Zhang Qinfang 
Published: August 2024

Abstract
Utilizing an innovative and highly light-absorbing photocathode, the direct conversion of hydrogen gas from Red Sea water is achieved. This involves creating a new nanocomposite thin film through a one-pot synthesis method, combining poly(O-chloroaniline) with trichalcogenides (MoS3) and MoO3 (MoS3–molebednium oxide/poly(o-chloroaniline)). This nanocomposite has remarkable morphological and optical properties with potential as a photocathode for hydrogen generation by harnessing the power of Red Sea water. This nanocomposite exhibits a unique semi-spherical architecture, with an average size of around 150 nm. These semi-spherical particles are surrounded by a dense network of fibers, forming a complex structure that provides ample space for trapping photons when exposed to light. The distinctive morphology significantly influences the optical properties of this nanocomposite, showing strong absorbance across a wide range of optical wavelengths up to ∼700 nm, with a promising bandgap of 1.75 eV. The hydrogen generation is quantified by measuring the generated photocurrent density (J
ph) as a function of the light incidence frequency using various optical filters at a fixed potential of −0.8 V. The highest J
ph values are recorded at −0.558 and −0.553 mA·cm−2 for wavelengths of 340 and 440 nm, respectively; the value reaches its maximum at the white light with a wavelength of −0.63 mA·cm−2. Elevating the temperature from 30°C to 50°C results in a substantial enhancement of the J
ph values, increasing from −0.63 to −0.71 mA·cm−2, respectively. This temperature increase leads to a noteworthy improvement in incidnce photon to current conversion from 1.85% to 2.22%. This photoelectrode demonstrates not only cost-effectiveness but also eco-friendliness, making it an attractive choice for H2 generation by Red Sea water as a natural, environmentally friendly, and economically viable hydrogen source. Consequently, this study holds significant promise for industrial applications due to its economic and eco-friendly characteristics.
Functional linguistics in life: an embodied approach in teacher education
Authors: Zhang Maverick Y. 
Published: August 2024

Abstract
Pedagogies developed from systemic functional linguistics are seen as valuable in supporting diverse students in both mainstream and language classrooms. Over the past decade, SFL also became a crucial component in teacher education programs particularly in the North American context, as it advances teachers’ knowledge of language and curriculum design focusing on the development of disciplinary literacy of minoritized multilingual learners. Drawing from data collected in a year-long classroom ethnographic study in the Southeastern U.S., this paper explores (1) how a range of embodied inquiry activities were designed as an integral part of a teacher education curriculum and (2) how these activities created entry points for diverse pre-service teachers and the teacher educator to grapple with functional linguistics and critically engage with their language use in everyday lives. Data analysis includes theory-informed thematic analysis and a mediated approach towards participants’ material-discursive trajectories across spatial and historical contexts. Findings show the affordances of using embodied activities to support teachers in making sense of key constructs from SFL in relation to their own lived experiences and cultural epistemologies. Implications point to the significance of innovative, culturally sustaining approaches toward both the teaching and use of SFL as well as the need for continued critical reflections and actions in changing classroom contexts.

Authors: Harris Jill S. , Berri David J. 
Published: August 2024

Abstract
We examine the impact of giving birth on athletic performance of players in the Women’s National Basketball Association. Using data from media reports and National Womens Basketball Players Association records we specify a productivity model and use a differences-in-means approach to investigate. We do not find any impact of giving birth on player performance in the sample. In the wake of the Gunnarsdottir maternity leave decision against Club Lyon, this research could help inform league policies concerning maternity leave and also contribute to the broader conversation about gender discrimination in the workplace based on perceptions of productivity before and after giving birth.
Enhancing precision and safety in metallographic sample preparation: Reduce the stochasticity and workload with robotization
Authors: Čermák J. , Ambrož O. , Jozefovič P. , Mikmeková Š. 
Published: August 2024

Abstract
Despite advancements in metallography automation, sample preparation remains largely semi-automated with isolated subprocesses like sectioning, grinding, and polishing. Leveraging modern technologies such as collaborative robotics, AI-driven computer vision, and advanced sensors could enable fully integrated automation. However, the diversity of processes requires skilled human oversight. Integrating user-friendly cobot interfaces may promote a synergistic workspace that enhances safety, reduces monotony, and supports complex studies and documentation aligned with open science principles. Our study explores cost-effective mini robots in critical preparation stages, highlighting steps toward complex automation in metallography.
Metallography of tailings from the Mansfeld copper mining area
Authors: Cloeren H.-H. , Haubner R. , Strobl S. 
Published: August 2024

Abstract
The copper slate deposit of the Mansfeld copper mining area was mined in the 19th and 20th century. Mineral collectors can still find traces of copper smelting activities on the slag heaps of the various copper smelters.
A piece from the Krug smelter slag heap mainly consists of Cu and Fe sulfides. The piece in question might be the intermediate product copper matte.
The pieces from Hettstedt and the August Bebel smelter contain clearly visible metallic copper. The Hettstedt specimen might be a piece of furnace lining with adhering slag. Cr and Mg could be found, suggesting that chromium magnesia was used as refractory material.
The piece from the August Bebel smelter contains up to 18 wt. % Cu. It does, however, not contain any sulfur. It is most likely Fe2SiO4 slag (fayalite) with a high proportion of FeO. The presence of Sn and Zn suggests that this slag was formed during the processing of bronze or brass.

Authors: Donnerbauer K. , Koch L. A. , Lingnau L. A. , Otto J. L. , Walther F. 
Published: August 2024

Abstract
For the metastable austenitic steel AISI 347 (X6CrNiNb18-10), various electropolishing parameters were evaluated by means of hardness testing, electron backscatter diffraction (EBSD), and atomic force microscopy. Depending on the chosen parameters, different surface characteristics could be achieved simply by only varying voltage, flow rate, and polishing time, although EBSD indexing was always possible. Differences in hardness of up to 20 HV0.5 and in microscopic roughness could be detected on otherwise comparable samples. Finally, the microstructure distribution of a hot rolled bar material with a diameter of 153 mm made from AISI 347 was characterized over the cross section using the previously determined parameter set. Here, insights about recrystallization during forming were concluded and δ-ferrite was differentiated from α’-martensite by kernel average misorientation and morphology.
Effects of heat treatment on the microstructure and corrosion behavior of manganese aluminum bronzes
Authors: Haubner R. , Strobl S. , Ball G. , Linhardt P. , Biezma M. V. 
Published: August 2024

Abstract
Due to a much lower nickel content, manganese aluminum bronzes (MAB) are a cost-effective alternative to nickel aluminum bronzes (NAB). When the material is processed, different microstructures are observable in the material which have an impact on the corrosion resistance of MAB alloys.
MAB samples were annealed at 900 °C and quenched in water. After that, annealing treatments at 600, 500, 400 and 300 °C for up to 24 h were performed and the samples were again quenched in water. Metallographic sections were prepared from all samples and potentiostatic corrosion tests at different potentials were performed in synthetic seawater.
It was found that the sample annealed at 900 °C and quenched in water as well as those samples which underwent a second annealing treatment at low temperatures for shorter times exhibited a greater corrosion tendency than those undergoing a second annealing treatment at higher temperatures.
X-ray diffraction measurements revealed that phase transformations and changes in grain size occurred during the annealing treatments. The increase in corrosion resistance as a result of annealing at higher temperatures is probably due to the strong intergrowth of the phases that are formed.
Widerfahrnisse des Sports. Zum unausgeschöpften Potenzial der philosophischen Anthropologie für die Sportwissenschaft
Authors: Gugutzer Robert 
Published: August 2024

Zusammenfassung
Die philosophische Anthropologie spielt in der gegenwärtigen Sportwissenschaft eine sehr randständige Rolle. Der Text möchte seinen Teil dazu beitragen, dies zu ändern, indem er die ungebrochene Bedeutung der philosophischen Anthropologie für die Sportwissenschaft nachweist. Dazu werden mit Wilhelm Kamlah, Hermann Schmitz und Gernot Böhme drei Autoren vorgestellt, die in der Sportwissenschaft bislang kaum zur Kenntnis genommen werden. Das Verbindende der philosophisch-anthropologischen Ansätze dieser drei Autoren ist die Überzeugung, dass das Menschsein fundamental durch Widerfahrnisse gekennzeichnet ist. Mit Rekurs auf Kamlah, Schmitz und Böhme lässt sich so der im Sport und der Sportwissenschaft vorherrschende Aktivismus um eine pathische Dimension ergänzen – in den Blick kommt der fundamentale Widerfahrnischarakter des Sports. Die argumentative Begründung hierfür erfolgt in drei Schritten: (1) Bezugnehmend auf die philosophische Anthropologie Kamlahs wird „Widerfahrnis“ als anthropologisches Prädikat eingeführt. (2) Mit der philosophischen Anthropologie von Schmitz erfolgt sodann der Fokus zum einen auf die leibliche Dimension von Widerfahrnissen, zum anderen auf die Gefühle als die für das menschliche Leben vermutlich bedeutendsten Widerfahrnisse. Dies wird an einem prototypischen Beispiel zur Verzweiflung im Sport illustriert. (3) Daran anknüpfend plädiert der Text mit Hilfe der philosophischen Anthropologie Böhmes für eine „Ethik des Pathischen“, die das im Sport vorherrschende Autonomiekonzept durch ein Souveränitätskonzept ersetzt.

Abstract
The radio-frequency (RF) transmit power deposition in tissue during magnetic resonance imaging (MRI) at ultra-high fields, i.e. B
0 ≥ 7 T, is a major challenge for pulse sequences requesting large flip angles. The absorbed RF energy can pose safety risk to patients as it is rising temperature in the tissue. The temperature can be accessed using MRI itself via the proton-resonance frequency (PRF) shift technique, which at low B
0 has been shown a valid MR thermometry method. In this paper, we explore the applicability of the PRF method to the assessment of local temperature in 7 T MRI procedures. To this end, we built a phantom filled with a material presenting electrical conductivity and permittivity close to muscle tissue. Tubes filled with oil were placed nearby the phantom to observe the time dependent B
0 drift. MRI phase images were acquired by gradient-echo (GRE) sequences at time points between spin-echo sequences with large flip angle allowing for a continuous assessment of the temperature during a 114 min RF-heating experiment. All acquired phase images were post-processed with attention to the time dependent instability of B
0, and, in addition, to potential spatial and temporal phase discontinuities, known as wraps. In this paper, we present a strategy to analyze and to unfold these phase wraps for large measurement fields and long acquisition times. It is shown that the PRF shift method is beneficial for the assessment of temperature at 7 T MRI. The temperature maps for axial and coronal planes display a temperature increase of approximately 3.5 °C during the time of the RF-heating experiment. Overall it is shown that B
0-drift correction and, importantly, the spatio-temporal unwrapping are an indispensable part of post-processing.
Evaluation of the Bursting Strength and Pilling Properties of Knitted Fabrics Produced from Recycled Yarns with Cotton Hard Waste
Authors: Uyanık Seval , Kaya Nacarkahya Tülin 
Published: August 2024

Abstract
In terms of sustainability, the textile industry has a significant impact because of intense mass consumption, fast fashion trends, short-term use of products, and thus the textile industry increases textile waste. Basic textile wastes are in solid forms of fibers, yarns, fabrics, cardboard, plastics, dyes, and chemicals containing wastewater, as well as gaseous wastes that cause emissions that release after textile processes. Recycling is the best solution for all textile wastes. In the recycling process of cotton, preconsumption wastes are generated in yarn production and the following production departments, whereas postconsumption wastes are used after classification according to both the structure and the color of the incoming wastes. Cotton hard waste is used at different blend ratios, and this study aims to reveal the effects of waste material on both the bursting strength and pilling properties of fabrics knitted with rotor yarns in different yarn counts. In the scope of sustainability, the findings show that the use of cotton hard waste at up to a 50 % ratio in circular knitted fabrics does not adversely affect the fabric’s bursting strength and pilling properties.

Published: August 2024

AbstractThis study developed and evaluated a new benchtop test method to measure the movements of different designs of intervertebral body fusion devices (IBFDs) under cyclic loads. The experimental method simulates and evaluates the movement resistance of intervertebral cages under flexion-extension cyclic loads experienced by the lumbar spine. The present method modifies a method developed previously and offers a possibility to be more clinically relevant and robust. This is because it allowed for closer achievement of levels of IBFD rotation reported in the literature and introduced the ability to control the flexion-extension movement and, consequently, the rotation of the cage more precisely. Polyurethane foam blocks were used as the bone substitute material. Optical and contactless displacement measurements were performed using a robust six degrees of freedom measuring system (OptiTrack) to evaluate the movements of the IBFD during testing. The results obtained by applying the new benchtop method showed greater sensitivity in capturing the implant movements in all directions measured, with magnitude significantly superior from Ribeiro et al. (2022). A test method to measure the movements of different IBFD designs was modified to better simulate and control the lumbar spine flexion-extension movements. The proposed benchtop methodology can evaluate the IBFD movements in all directions to more efficiently discriminate in a potentially standardized test the efficacy of different IBFD designs.

Abstract
In view of problems such as the decline in strength of cement paste and latex exudation caused by the addition of conventional latex, JAS soap-free latex (JAS latex) was prepared by soap-free emulsion polymerization technology. JAS latex had the characteristics of low viscosity, uniform particle size, good dispersity of particles, and good compatibility with cement admixtures. JAS latex had little impact on the fluidity of oil-well cement paste. The free liquid of the cement paste with 10 % JAS latex was 0 %, and its liquid-loss content was 43 mL. When the JAS cement paste was cured at 90°C, its compressive strength was 34.08 MPa. When the curing temperature was 70°C, the bond strength between the paste and metal casing reached 4.95 MPa. Combining the results tested by X-ray diffraction, scanning electron microscopy, and atomic force microscopy showed that JAS latex did not affect the hydration process of oil-well cement, had good film-forming ability in cement paste, and improved the density and impact resistance of the cement paste. It is helpful to improve the sealing integrity and sealing ability of cement sheath in cementing engineering and ensure the safe and efficient development of oil and natural gas resources.
