Published: September 2023

This research is motivated by players who have explosive leg muscles in the poor category, because extracurricular volleyball players at SMP 2 Koto Baru have never held a special program that focuses on physical exercise, especially on the players' leg muscles, but only focuses on on technical training. This can be seen through the temporary test results obtained through the smash jump test. In ongoing extracurricular activities, researchers saw when players did volleyball exercises where the player when making a jump still had a low jump, so that he had difficulty in smashing. Seeing these conditions, how important is the explosive power of leg muscles in volleyball. To improve the physical condition, an exercise that is in accordance with the dominant exercise in training the leg muscles is needed. This type of research is research & development or Research and Development (R&D). The model development uses the ADDIE model which consists of 5 stages, namely analysis, design, development and evaluation. The five stages were carried out by analyzing the needs of students. Then the validation test by 3 validators (expert team), practicality test by the PJOK teacher, after the model is categorized as valid and practical, then the effectiveness test is carried out by 10 players by doing a smash jump test. The results of the research on the development of the exercise model taught by the volleyball leg muscle training model in the validity test obtained percentage data with an average of 82.22% categorized as very valid, the practicality test by PJOK teachers with a percentage of 96% and players with a percentage of 78.4% categorized as practical. , while the effectiveness test with a percentage of 90% is categorized as very effective.

What has changed? Care home work during the pandemic in Jack Thornes’ Help: No one is coming
Authors: Goulding Anna
Published: September 2023

The article examines how Jack Thornes’ Help: No one is coming (2021) politicizes the public sphere of dementia care. The drama’s focus on care homes in the UK during the pandemic addresses the impact of the crisis and simultaneously serves to highlight the longstanding issues faced by an under-funded and under-valued sector. This paper aims to examine how Help reflects, but also writes societal scripts about how we care for our populations with dementia and the people we pay to care for them. In highlighting the pressure care homes are under, it is important to look at our collective societal attitude to care, and whether we are prepared to cover higher wages that would be required if care work became a desirable career with progression. In examining the purpose of, and effectiveness of the drama’s rhetoric, I aim to investigate how ideological notions of care and practical care work are articulated. Finally, I ask whether Help succeeds in mobilizing audiences to press for change or whether in its portrayal of care homes, the drama enables them to accept the status quo.

Published: September 2023

It-fagligheden er under udvikling i den danske grundskole og i gymnasiale uddannelser med fagbeskrivelsen af informatik til gymnasieskolen og forsøgsfaget teknologiforståelse i grundskolen. Der foreligger endnu ikke forskningsbaserede analyser af de to fagligheders samstemthed til trods for, at elever, undervisere og uddannelsesinstitutioner forventeligt vil afsøge en sammenhæng mellem faglighederne. Denne artikel bidrager med en teoretisk analyse af disse to fagligheders formål og identitetsbeskrivelse, fra henholdsvis læreplan og læseplan, med henblik på at etablere en funderet forståelse for faglighedernes forskelle og ligheder.  Artiklen gennemgår de to udviklingsprocesser, der ledte til de to fagbeskrivelser. Dernæst analyserer vi formåls- og identitetsbeskrivelserne for de to fagligheder kvalitativt og dernæst kvantitativt. Resultaterne viser et fokus på hvorfor eleverne skal lære i beskrivelsen af teknologiforståelse, mens beskrivelsen af informatikfaget i højere grad adresserer hvad eleverne skal lære. Endelig diskuterer vi de forskelle og uligheder, som optræder i formål og identitetsbeskrivelserne med henblik på at uddrage mulige retninger for fremtidig forskning og udvikling.

Mechanical stress-thermodynamic phase-field simulation of lithium dendrite growth in solid electrolyte battery
Authors: Geng Xiao-Bin , Li Ding-Gen , Xu Bo ,   School of Energy and Power Engineering, Huazhong University of Science and Technology, Wuhan 430074, China
Published: September 2023

Growth of lithium dendrites in solid state batteries is an important factor that disturbs their commercial applications. The growth of lithium dendrites at the interface of lithium metal anode will not only lead to the decrease of battery energy efficiency, but also cause combustion, explosion and other safety problems. In order to explore the factors and methods that inhibit the growth of lithium dendrites, the phase-field theory is used to simulate the growth of lithium dendrites in polymer solid electrolyte batteries, and a phase-field model of lithium dendrite growth coupled with mechanical stress and thermal field is established. The effects of key physical factors such as ambient temperature, solid electrolyte Young’s modulus and external stress on dendrite growth and their acting principles are discussed and analyzed. The results show that under the conditions of high temperature, high solid electrolyte Young’s modulus and external stress, the growth of lithium dendrites is slow, the number of long dendrites is small, and the electrodeposition is more uniform. In addition, the effects of Young’s modulus of solid electrolyte and ambient temperature on the growth of lithium dendrites in a common range are compared with each other. It is found that the inhibition effect of changing Young’s modulus of solid electrolyte on the maximum length of lithium dendrites is 19% higher than that caused by the change of ambient temperature.
A double-decomposition based parallel exact algorithm for the feedback length minimization problem
Authors: Shang Zhen , Hao Jin-Kao , Ma Fei
Published: September 2023

Product development projects usually contain many interrelated activities with complex information dependences, which induce activity rework, project delay and cost overrun. To reduce negative impacts, scheduling interrelated activities in an appropriate sequence is an important issue for project managers. This study develops a double-decomposition based parallel branch-and-prune algorithm, to determine the optimal activity sequence that minimizes the total feedback length (FLMP). This algorithm decomposes FLMP from two perspectives, which enables the use of all available computing resources to solve subproblems concurrently. In addition, we propose a result-compression strategy and a hash-address strategy to enhance this algorithm. Experimental results indicate that our algorithm can find the optimal sequence for FLMP up to 27 activities within 1 h, and outperforms state of the art exact algorithms.
Maintenance of xylem hydraulic function during winter in the woody bambooPhyllostachys propinquaMcClure
Authors: Dai Yongxin , Wang Lin , Wan Xianchong
Published: September 2023

Background

Frost is a common environmental stress for temperate plants. Xylem embolism occurs in many overwintering plants due to freeze-thaw cycles, so coping with freeze-thaw-induced embolisms is essential for the survival of temperate plants.

Methods

This study was conducted onPhyllostachys propinquaMcClure, a woody bamboo species that was grown under natural frost conditions to explore its responses to winter embolisms. From autumn to the following spring, the following measurements were recorded: predawn branch and leaf embolism, branch and leaf relative water content (RWC), root pressure and soil temperature, xylem sap osmotic potential, branch and leaf electrolyte leakage (EL), branch nonstructural carbohydrate (NSC) content and leaf net photosynthetic rate.

Results

P. propinquahad a mean vessel diameter of 68.95 ±1.27 µm but did not suffer severe winter embolism, peaking around  60% in winter (January), with a distinct reduction in March when root pressure returned. Leaves had a more severe winter embolism, up to 90%. Leaf RWC was much lower in winter, and leaf EL was significantly higher than branch EL in all seasons. Root pressure remained until November when soil temperature reached 9 °C, then appeared again in March when soil temperatures increased from −6 °C (January) to 11 °C. Xylem sap osmotic potential decreased from autumn to winter, reaching a minimum in March, and then increasing again. Soluble sugar (SS) concentration increased throughout the winter, peaked in March, and then decreased.

Conclusions

These results suggest that (1) there is a hydraulic segmentation between the stem and leaf, which could prevent stem water loss and further embolization in winter; (2) maintenance of root pressure in early winter played an important role in reducing the effect of freeze-thaw cycles on the winter embolism; (3) the physiological process that resulted in a decrease in xylem sap osmotic potential and tissue water content, and an accumulation of SS associated with cold acclimation also aided in reducing the extent of freeze-thaw-induced embolism. All these strategies could be helpful for the maintenance of xylem hydraulic function of this bamboo species during winter.
La huella del carbón: procesos de decadencia y estrategias reconversión de paisajes postindustriales: el caso de Lota
Authors:   ,   Pontificia Universidad Católica de Chile. Escuela de Arquitectura, Aillón Ferreira Sarah
Published: September 2023

Los paisajes postindustriales que nos legaron las industrias de los siglos XIX y XX en Chile son el vestigio de una época de auge del desarrollo económico y social del país y el resultado de procesos de transformación territorial, social y cultural, siendo símbolos de los antiguos polos de desarrollo de ciudades. En estos paisajes es posible percibir las huellas del hombre sobre el territorio, adquiriendo valores de paisaje cultural al haber sido parte fundamental en la construcción de la identidad y forma de vida que han quedado plasmadas en él (Alba, 2016). En Chile, la zona del Golfo de Arauco se configuró como el principal polo de desarrollo de la minería del carbón, la que dio lugar al crecimiento de una serie de ciudades que construyeron su identidad y raíces en base a la cultura minera, teniendo su auge en Lota, configurándose como una de las ciudades de mayor relevancia a nivel nacional y sufriendo como consecuencia de la industria, la alteración de su paisaje, dando lugar a uno nuevo y característico a través de la modificación de aspectos geográficos y morfológicos del territorio, la trama urbana y la construcción de edificaciones e infraestructuras, las cuales definieron la esencia del paisaje cultural de la zona y que son elementos identitarios hasta el día de hoy. Con la crisis y cierre de las industrias durante el siglo XX, se configuró un largo cementerio de ciudades ruinas en el país, y Lota, corazón de la industria, cayó en un proceso de progresivo abandono, siendo actualmente uno de los principales ejemplos a nivel nacional de un paisaje postindustrial en estado de degradación, donde la presencia de edificaciones como vestigios de la industria carbonífera se concentra hacia el sector costero de Lota Alto en el llamado sector industrial Chambeque, presentándose una situación de conflicto en el que confluyen diferentes actores generadores de riesgo, como la existencia de un área en abandono cerca del centro urbano de la ciudad, la huella ecológica por la presencia de acumulación de material escorial, las remociones en masa y la pérdida progresiva de la memoria asociada a la historia industrial, donde las ruinas son una huella que recuerda las raíces mineras que forjaron la identidad cultural de la ciudad. A partir de esto, el presente trabajo busca estudiar y analizar los imaginarios y procesos involucrados en la construcción de los paisajes postindustriales apuntando a la definición de los elementos que permiten la conservación y reconversión de estos sitios. El análisis se aplica al caso del sitio de Chambeque, planteando oportunidades y buscando los lineamientos y estrategias de intervención para la conservación de un sitio con ruinas postindustriales, planteando el rescate de la memoria y la puesta en valor del patrimonio cultural e histórico de la ciudad.

The science of controlling materials at the nanoscale is known as nanotechnology. Working with the smallest particles conceivable gives rise to aspirations for increasing agricultural production by running into issues that can't be solved traditionally. In the management aspects, attempts are made to restore soil fertility by releasing fixed nutrients, as well as to boost the efficacy of applied fertilizer with the aid of nano clays and zeolites. With the aid of nano biosensors and satellite systems, the input requirements for crops are determined in controlled environments for agriculture and precision farming based on needs, and the necessary quantities are given at the appropriate times and locations. To combat the issues of managing perennial weeds and depleting the weed seed bank, nano herbicides are being developed. By using targeted delivery, slow/controlled release, and conditional release mechanisms, nanostructured formulations could more accurately time the release of their active ingredients in response to biological needs and environmental cues. According to studies, using nano fertilizers improves the efficiency with which nutrients are used, lessens soil toxicity, reduces the frequency of treatment, and minimizes any potential side effects from overdosing. Because of this, nanotechnology, especially in underdeveloped nations, has tremendous potential for attaining sustainable agriculture. To increase agricultural productivity, new technologies are frequently used in agriculture. Employing nanoparticles in agriculture is known as "nanoagriculture," and these particles will have positive effects on crops.

Soil health methods, including cover cropping, crop rotation, and conservation tillage, yield a multitude of environmental and economic benefits. These advantages encompass carbon sequestration, soil erosion mitigation, nutrient leaching prevention, and the establishment of habitats for beneficial insects and pollinators. Nonetheless, there exists a comparatively limited degree of awareness and implementation of soil fertility control techniques. Soil health practices have emerged as a unifying factor among diverse stakeholders within the agricultural sector, fostering collaboration amongst the scientific community and facilitating economic advancement for the broader populace. Insufficient data pertaining to soil health and the reluctance to use soil health management strategies are seen as substantial barriers in augmenting agricultural productivity inside the nation. A research investigation was undertaken in the Hisar area of Haryana to evaluate the extent of knowledge and use of soil health measures. So, randomly 120 farmers were selected for the investigation and a well-developed interview schedule was developed to meet the objectives. The results of the study indicate that certain soil health measures have achieved extensive recognition, including land levelling, field bunding, irrigation with high-quality water, and the utilization of green manure/organic manure. Nevertheless, many agricultural strategies, such as the use of reduced tillage techniques alongside cover crops and the adoption of integrated farming systems, exhibit relatively lower rates of adoption. In general, the current rate of implementation of soil health measures is quantified at 40.72 percent, suggesting a necessity for enhancement.

Several studies have shown that most condiments consumed in Nigeria today are fortified with chemicals that alter the nature, and negatively affect organs and cells. Several condiments   have been developed from fermented foods in order to control this ugly situation and to produce a non-toxic condiment with improve health qualities. The aim of this study was to evaluate the toxicity of the fermented soybean condiments produced using indigenous fermenters. Soybean (Glycine max) sample was fermented with indigenous microorganisms isolated from 7 days old fermented soybean sample; this was oven-dried, pulverized and packaged in a cleaned sterile screw capped container. The toxicity was evaluated using in vivo technique. Lactobacillus plantarum strain ZS 2058 (L), Bacillus subtilis strain 168 (B) and Saccharomyces cerevisiae strain YJM555 (Y) were the indigenous microbes used singly and in consortium for the production of light to dark brown condiments with water activity ranging from 0.27 – 0.37 for the fermented soybean in the plate and 0.22 - 0.36 for the fermented soybean wrapped with Thaumatococcus danielli leaves (called Uma in Igbo and Ewe eran in Yoruba). No death was recorded from the experimental rats.The experimented rats showed significant (P<0.05) increased in body weight, no evidence of severe deformities in the organs and cells, slight or no increased in organ weights and these were statistically non-significant (P>0.05). Therefore condiments produced from fermentation of soybean using indigenous B, L, Y, BL and BLY are recommended safe and non-toxic and those fermented in plastic plates using BLY were most efficient, preferable and acceptable.

Importance

Prenatal cardiac screening of the first and second trimesters has had a major impact on postnatal prevalence of congenital heart defects (CHDs), rates of termination of pregnancy (TOP), and outcomes among children born alive with CHDs.

Objective

To examine the prenatal and postnatal incidence of major CHDs (ie, necessitating intervention within the first year of life), detection rate trends, rates of TOP, and the association of cardiac screening with postnatal outcomes.

Design, Settings, and Participants

In this cross-sectional study, 3827 fetuses with antenatally diagnosed major CHDs in the Czech Republic (population 10.7 million) between 1991 and 2021 were prospectively evaluated with known outcomes and associated comorbidities. Prenatal and postnatal prevalence of CHD in an unselected population was assessed by comparison with a retrospective analysis of all children born alive with major CHDs in the same period (5454 children), using national data registry. Data analysis was conducted from January 1991 to December 2021.

Main Outcomes and Measures

Prenatal detection and postnatal prevalence of major CHDs and rate of TOPs in a setting with a centralized health care system over 31 years.

Results

A total of 3 300 068 children were born alive during the study period. Major CHD was diagnosed in 3827 fetuses, of whom 1646 (43.0%) were born, 2069 (54.1%) resulted in TOP, and 112 (2.9%) died prenatally. The prenatal detection rate increased from 6.2% in 1991 to 82.8% in 2021 (P < .001). Termination of pregnancy decreased from 70% in 1991 to 43% (P < .001) in 2021. Of 627 fetuses diagnosed in the first trimester (introduced in 2007), 460 were terminated (73.3%). Since 2007, of 2066 fetuses diagnosed in the second trimester, 880 (42.6%) were terminated, resulting in an odds ratio of 3.6 (95% CI, 2.8-4.6; P < .001) for TOP in the first trimester compared with the second trimester. Postnatal prevalence of major CHDs declined from 0.21% to 0.14% (P < .001). The total incidence (combining prenatal detection of terminated fetuses with postnatal prevalence) of major CHD remained at 0.23% during the study period.

Conclusions and Relevance

In this cross-sectional study, the total incidence of major CHD did not change significantly during the 31-year study period. The prenatal detection of major CHD approached 83% in the current era. Postnatal prevalence of major CHD decreased significantly due to early TOPs and intrauterine deaths. The introduction of first trimester screening resulted in a higher termination rate in the first trimester but did not revert the overall decreasing trend of termination for CHDs in general.
Development of a LINAC head model for the CyberKnife VSI‐System using EGSnrc Monte Carlo system
Authors: Thiele Martin , Galonske Kirsten , Ernst Iris , Mack Andreas
Published: September 2023

Introduction

In order to understand the interaction processes of photons and electrons of the CyberKnife VSI‐System, a modeling of the LINAC head must take place. Here, a Monte Carlo simulation can help. By comparing the measured data with the simulation data, the agreement can be checked.

Materials and methods

For the Monte Carlo simulations, the toolkit EGSnrc with the user codes BEAMnrc and DOSXZYnrc was used. The CyberKnife VSI‐System has two collimation systems to define the field size of the beam. On the one hand, it has 12 circular collimators and, on the other, an IRIS‐aperture. The average energy, final source width, dose profiles, and output factors in a voxel‐based water phantom were determined and compared to the measured data.

Results

The average kinetic energy of the electron beam for the CyberKnife VSI LINAC head is 6.9 MeV, with a final source width of 0.25 cm in x‐direction and 0.23 cm in y‐direction. All simulated dose profiles for both collimation systems were able to achieve a global gamma criterion of 1%/1 mm to the measured data. For the output factors, the deviation from simulated to measured data is < 1% from a field size of 12.5 mm for the circular collimators and from a field size of 10 mm for the IRIS‐aperture.

Conclusion

The beam characteristics of the CyberKnife VSI LINAC head could be exactly simulated with Monte Carlo simulation. Thus, in the future, this model can be used as a basis for electronic patient‐specific QA or to determine scattering processes of the LINAC head.
