Helium reservoirs in iron nanoparticles on the lunar surface
Authors: Cymes Brittany A. , Burgess Katherine D. , Stroud Rhonda M.
Published: April 2024

The Moon’s surface is directly exposed to the space environment and subject to alteration by space weathering. One agent of space weathering, the solar wind, enriches the lunar surface with helium. Although we understand how helium is delivered to the Moon, certain aspects of helium concentration processes on the surface remain unknown, such as why impact-generated glass aggregates contain more helium than equally sized soil grains of other types. Here we have analyzed the contents of vesicular iron nanoparticles in lunar impact glasses using aberration-corrected scanning transmission electron microscopy and electron energy loss spectroscopy and show that the nanoparticles contain high concentrations of helium (10-24 atoms/nm3). The widespread occurrence of vesicular iron nanoparticles among lunar samples suggests that they may be an important helium reservoir. These results also suggest that space weathering of iron-rich minerals plays a role in helium sequestration on the Moon and potentially on other airless bodies.
SimuCell3D: three-dimensional simulation of tissue mechanics with cell polarization
Authors: Runser Steve , Vetter Roman , Iber Dagmar
Published: April 2024

The three-dimensional (3D) organization of cells determines tissue function and integrity, and changes markedly in development and disease. Cell-based simulations have long been used to define the underlying mechanical principles. However, high computational costs have so far limited simulations to either simplified cell geometries or small tissue patches. Here, we present SimuCell3D, an efficient open-source program to simulate large tissues in three dimensions with subcellular resolution, growth, proliferation, extracellular matrix, fluid cavities, nuclei and non-uniform mechanical properties, as found in polarized epithelia. Spheroids, vesicles, sheets, tubes and other tissue geometries can readily be imported from microscopy images and simulated to infer biomechanical parameters. Doing so, we show that 3D cell shapes in layered and pseudostratified epithelia are largely governed by a competition between surface tension and intercellular adhesion. SimuCell3D enables the large-scale in silico study of 3D tissue organization in development and disease at a great level of detail.

The Feel of Speech: Multisystem and Polymodal Somatosensation in Speech Production
Authors: Kent Raymond D.
Published: April 2024

Purpose:

The oral structures such as the tongue and lips have remarkable somatosensory capacities, but understanding the roles of somatosensation in speech production requires a more comprehensive knowledge of somatosensation in the speech production system in its entirety, including the respiratory, laryngeal, and supralaryngeal subsystems. This review was conducted to summarize the system-wide somatosensory information available for speech production.

Method:

The search was conducted with PubMed/Medline and Google Scholar for articles published until November 2023. Numerous search terms were used in conducting the review, which covered the topics of psychophysics, basic and clinical behavioral research, neuroanatomy, and neuroscience.

Results and Conclusions:

The current understanding of speech somatosensation rests primarily on the two pillars of psychophysics and neuroscience. The confluence of polymodal afferent streams supports the development, maintenance, and refinement of speech production. Receptors are both canonical and noncanonical, with the latter occurring especially in the muscles innervated by the facial nerve. Somatosensory representation in the cortex is disproportionately large and provides for sensory interactions. Speech somatosensory function is robust over the lifespan, with possible declines in advanced aging. The understanding of somatosensation in speech disorders is largely disconnected from research and theory on speech production. A speech somatoscape is proposed as the generalized, system-wide sensation of speech production, with implications for speech development, speech motor control, and speech disorders.

Authors: Ravshanova Nilufar , Khalilov Nasriddin , Otayarova Gulshoda , Kosimova Shaxnoza , Palvanov Sobirjon
Published: April 2024

In this work, combined crops of mung bean and cotton were studied in the conditions of the Tashkent region, Kibray region. The work evaluates such indicators of combined crops of mungbean and cotton as the area and time equivalence coefficient (ATER), the aggressiveness of crops, as well as the influence on these indicators of different doses of fertilizers in combination with different maximum field humidity. The value of ATER, that is, the coefficient of equivalent area and time, depended on the sowing methods, plant density, and duration of the growing season. Aggressiveness in the combined sowing of mung bean and cotton was not significant. Analysis of the studies showed that the use of different doses of fertilizers and maximum field humidity did not affect the aggressiveness of mung bean and cotton crops in combined sowing. The results obtained show the possibility of using combined crops in the conditions of Uzbekistan.
A semi-implicit homogeneous discretized differentiator based on two projectors: experimental validation on a cable-driven parallel robot
Authors: Michel Loic , Métillon Marceau , Caro Stéphane , Ghanes Malek , Plestan Franck , Barbot Jean-Pierre , Aoustin Yannick
Published: April 2024

This work is dedicated to the application of a semi-implicit homogeneous differentiator to estimate the angular velocity and the angular acceleration of each of the eight electric motors of theCRAFTcable-driven parallel robot from the recording of the angular position of their respective output shaft. These motors drive the winding or unwinding of eight cables to move the robot moving-platform. The results show that this differentiator, whose the definition is respectively based on two projectors, is an extremely efficient tool for estimating the angular velocities and accelerations of the eight motors. These estimated velocities and accelerations are much less noisy than their reference signals obtained by backward difference. Moreover, the estimated quantities obtained with this differentiator are successfully compared to those obtained by a non-linear observer based on the interpolation and numerical difference of the measured position variable. Those promising results will definitely contribute to a better control of theCRAFTrobot.
On the influence of compositional variations in high chrome cast iron: an assessment of microstructure and mechanical behaviour
Authors: Nelwalani Brayner Ndivhuwo , van der Merwe Josias , Munyangane Vhonani , Cader Zaynab Adam , Rampaku Thato , Klenam Desmond
Published: April 2024

In this study, the influence of compositional variation on the microstructure and properties of high chrome cast iron produced in jobbing foundries was evaluated. The aim was to determine whether compositional analysis alone is sufficient for qualifying acceptable high chrome cast iron components made in jobbing foundries. The compositions of the melts were analysed using optical emission spectroscopy. They were then compared with targeted compositions for commercially acceptable high chrome cast iron components. Equilibrium phases and phase transition temperatures of the different high chrome cast iron were calculated using the measured compositions as input on Thermo-Calc. Thermal analyses were also carried out to obtain the cooling profiles of each melt using ATAS MetStar software. The predictions from Thermo-Calc and ATAS Metster thermal analyses were then compared with experimentally determined optical and scanning electron images of the alloys. Hardness, fracture toughness, and wear resistance were determined both in the as-cast and heat-treated conditions. The results showed that even slight compositional variations significantly influence the microstructure and mechanical properties of high chrome cast iron, even when the compositions fall within the targeted compositional range typically accepted for industrial applications. Therefore, the study suggests that using compositional analysis alone is not sufficient for accepting high-quality high chrome cast iron components for industrial applications.

Authors: Yahbi Mohammed , Keli Abdelhafid , El Alami Nabila , Nabloussi Abdelghani , Maataoui Abdelwahed , Daoui Khalid
Published: April 2024

Rapeseed meal (RSM) is known for its high nutritional quality as animal feed. However, there has been little studies on the effect of nitrogen fertilization on RSM chemical composition, mainly neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), and ash content. Therefore, this study was carried out to evaluate the effect of nitrogen application rate on chemical composition of RSM in interaction with different spring rapeseed varieties (Brassica napus L). A field experiment was conducted during 2018/19 cropping season at the experimental station of the Ecole Nationale d’Agriculture de Meknès” according to a split-plot design with three replications, using six nitrogen application rates, as main plot, and six rapeseed varieties, as subplot. After seeds harvest and oil extraction, meals derived from the different treatments were used in this study. Results showed that increasing nitrogen rate from 0 to 120 kg N ha−1 led to a significant rise in meal yield up to 74.58%. A positive effect of nitrogen fertilization was observed on dry matter, protein content and ash content, recording the highest values at 120 kg N ha−1 treatment. However, cellulose and lignin content were affected negatively by nitrogen fertilization. The nitrogen supply of 150 kg N ha−1 resulted in a reduction of ADF and ADL contents by 23% and 28%, respectively, compared to the unfertilized control (N0). Variability within rapeseed varieties for all parameters except dry matter and ADL content was highlighted.

Published: April 2024

Garment industry sewing involves 8 hours of sitting in an unnatural, uncomfortable position that can lead to muscle pain and injuries. This study aims to evaluate complaints and risks of MSDs in sewing work in the garment industry. Identify complaints using the Nordic Body Map (NBM) and Assessment of Repetitive Task (ART) methods. Based on the results of identification with NBM of sewing operators, it was found that the body parts where complaints occurred were the waist at 89%, the right calf at 61%, the buttocks at 53%, and the back at 50% from a total of 36 sewing operators. The results of analysis using the Assessment of Repetitive Task (ART) method show that all sewing operators experience musculoskeletal disorders in the moderate level exposure category so that further review of the sewing workstation is needed. The recommended improvement is in the form of improving posture to reduce the complaints felt. Relevance for industry: this study focuses on sewing work-related factors and other risk factors, which will help researchers to better understand the risk of MSDs in the garment industry. These risk factors must be considered when creating and implementing ergonomic aspects to prevent and reduce musculoskeletal discomfort.

Published: April 2024

Es gibt umfangreiche Evidenz, dass Bewegung einen entscheidenden Beitrag zu
Krankheitsprävention und Therapieerfolg leisten kann. Dennoch besteht in der
Bevölkerung, besonders bei Patient*innen mit chronischen Erkrankungen, eine
Lücke zwischen der vorhandenen Evidenz und der tatsächlichen Anwendung von
Bewegung als Therapie, eine sogenannte „evidence-to-practice gap“.

Implementierungsforschung kann helfen, diese Lücken zu schließen, beispielsweise
unter Verwendung theoretischer Frameworks. Der Einsatz von
Mixed-Methods-Ansätzen (eine Kombination aus qualitativer und quantitativer
Datenerhebung und -analyse) innerhalb dieser Frameworks ermöglicht ein
umfassendes und tiefergehendes Verständnis von evidence-to-practice-gaps.

Daher sollte ihre Anwendung in Zukunft verstärkt werden, um
evidence-to-practice-gaps in der Gesundheitsversorgung besser zu verstehen und
zu überwinden und so eine optimale, patientenorientierte Versorgung
sicherzustellen.

Intermittierendes Hypoxietraining – hin zu mehr Energie und
Leistung
Authors: Marshall Robert Percy , Gartenbach Andrea
Published: April 2024

Menschliche Leistung wird direkt durch die mitochondriale Energiegewinnung unserer Zellen bestimmt.
Unsere Fähigkeit, dabei zu regenerieren und auf neue Herausforderungen adäquat zu reagieren, wird
maßgeblich durch unser vegetatives Nervensystem reguliert. Gesunde Mitochondrien und ein
funktionsfähiges Vegetativum sind daher von entscheidender Bedeutung (für High Performer und
Athleten). Selbst durch kurze hypoxische Trainings wird eine signifikante Anzahl von Genen –
vorrangig des HIF-1α und weiterer Wachstumsfaktoren – positiv beeinflusst, was zu einer indirekten
Beeinflussung der Belastungstoleranz führt. Der Einfluss auf die zelluläre und nervale
Regenerationsfähigkeit ist für den Sportler in Hinblick auf die Leistungsfähigkeit von enormer
Bedeutung. Durch intermittierendes Hypoxietraining können nicht nur die parasympathische Aktivität

Aim The aim of this study is to investigate whether computer-aided, semi-automated 3D lung lobe quantification can support decision-making on PE diagnosis based on the ventilation-perfusion ratio in clinical practice.

Methods A study cohort of 100 patients (39 male, 61 female, age 64.8±15.8 years) underwent ventilation/perfusion single photon emission computed tomography (V/Q-SPECT/CT) to exclude acute PE on SPECT/CT OPTIMA NM/CT 640 (GE Healthcare). Two 3D lung lobe quantification software tools (Q. Lung: Xeleris 4.0, GE Healthcare and LLQ: Hermes Hybrid 3D Lung Lobar Quantification, Hermes Medical Solutions) were used to evaluate the numerical lobar ventilation/perfusion ratio (VQR) and lobar volume/perfusion ratio (VPR). A test of linearity and equivalence of the two 3D software tools was performed using Pearson, Spearman, quadratic weighted kappa and the mean squared deviation for VPR/VQR. An algorithm was developed that identified PE candidates using ROC analysis. The agreement between the PE findings of an experienced nuclear medicine expert and the calculated PE candidates was represented by the magnitude of the YOUDEN index (J) and the size of the area under the receiver operating curve (AUC).

Results Both 3D software tools showed good comparability. The YOUDEN index for QLUNG(VPR/VQR)/LLQ(VPR/VQR) was in the range from 0.2 to 0.5. The mean AUC averaged over all lung lobes for QLUNG(VPR) was 0.66, CI95%: ±14.0%, for QLUNG(VQR) 0.66, CI95%: ±13.3%, for LLQ(VPR) 0.64, CI95%: ±14.7% and for LLQ(VQR) 0.65, CI95%: ±13.1%.

Conclusion This study reveals that 3D software tools are feasible for numerical PE detection. The clinical decision can be supported by using a numerical algorithm based on ROC analysis.
Brachioradial Pruritus Caused by Cervical Disc Herniation Precipitated by Trauma Treated with Anterior Cervical Discectomy and Fusion: Report of Two Cases and Review of the Literature
Authors: Hernandez Nicholas S. , Rogers James L. , Pham Martin H.
Published: April 2024

Brachioradial pruritis (BRP) is a rare form of dermatomal pruritis that appears to be caused both by cervical radiculopathy and exposure to ultraviolet-light, although the exact pathophysiology for the manifestation of these symptoms remains to be determined. A diagnosis of BRP is typically confirmed with the “ice-pack” test and evidence of cervical spine pathology using magnetic resonance imaging. Treatment options consist of application of ice, reduction in sun exposure, and topical capsaicin, antiepileptics, or tricyclic antidepressants. Patients with refractory symptoms and cervical spine pathology may be candidates for surgical decompression, particularly at the C5 and C6 levels. However, there are currently no established guidelines to treat BRP, or surgical procedures that have shown to be superior. Here, we report two cases of cervical disc herniations after traumatic events that presented as BRP. Both cases were successfully treated with anterior cervical discectomy and fusion with complete resolution of symptoms.

Objective An individual's chronotype affects circadian characteristics associated with bedtime, waking, and other daily activities. It is known that academic achievement is strongly dependent on personality traits. The present study aimed to investigate the relationship regarding chronotype, quality of life, and academic performance of university students by comparing three educational fields: medicine, technology, and art.

Materials and Methods The present cross-sectional study was conducted with 400 medicine, technology, and art students enrolled at universities in Tehran between2018 and 2019, with convenience sampling from January 2020 to January 2021. The students filled out online questionnaires, including a demographics questionnaire, a quality of life assessment questionnaire (the World Health Organization Quality of Life: Brief Version, WHOQOL-BREF), the Morningness-Eveningness Questionnaire (MEQ), the Pittsburgh Sleep Quality Index (PSQI), and the Depression, Anxiety, and Stress Scale-21 items (DASS-21). The statistical analysis was performed using the IBM SPSS Statistics for Windows software, version 22.0 (p < 0.05).

Results A total of 400 students were enrolled in the present study, including 115 medicine, 153 technology, and 132 art students (67.3% of female and 33.7% of male subjects, with a mean age of 21.06 ± 2.063 years). In spite of the absence of significant differences among the chronotypes of the three groups, there was a significant correlation regarding the chronotypes in all groups and quality of life (p = 0.005). Morning-type individuals presented better quality of life and better quality of sleep (p < 0.001; r = 0.175). No significant associations were found involving the students' academic performance and their chronotypes (p > 0.05; r = 0.026).

Conclusion Considering the chronotype's effect of improving the quality of life of students and, therefore, their academic performance, more studies are essential to effectively improve the academic performance of individuals with different chronotypes.

Published: April 2024

Objective To investigate psychosocial factors at work, sleep characteristics, and the correlation between these aspects in healthcare workers.

Material and methods A cross-sectional e-survey study was conducted with 125 workers of the Brazilian healthcare system, mostly from the Southeast region, from June 2021 to April 2022. Self-administered questionnaires in Google Forms were used to collect data on personal and occupational characteristics, psychosocial factors (Copenhagen Psychosocial Questionnaire), and sleep quality (Pittsburg Sleep Quality Index). Descriptive statistics and a point biserial correlation test were performed.

Results The most reported factors in the risk zone were burnout (86%), stress (81%), emotional demands (75%), work pace (61%), and work-family conflicts (55%). Most participants were classified as poor sleepers (74%), especially nursing technicians/assistants (86%). Burnout (rpb = 0.33) and inadequate predictability (rpb = 0.30) were associated with poor sleep quality.

Conclusion Intervention strategies to decrease burnout and increase predictability at work may assist in improving sleep quality among healthcare workers.

Introduction Admission to university influences lifestyle behaviors and is marked by a daily routine of accumulation of activities that can interfere with sleep duration, affecting food choices and meal consumption habits throughout the day.

Objective To analyze the association between short sleep duration and skipping main meals among university students.

Materials and Methods We conducted a cross-sectional study with 1,608 university students aged between 16 and 25 years, who were enrolled in full-time undergraduate courses at a public university in the Midwestern region of Brazil. Information on skipping breakfast, lunch, and dinner was collected through the question “On average, how often do you eat the following meals?”. Given the lack of a uniform criterion to define “skipping a meal”, in the present study, any answer that did not correspond to the daily consumption of the meal was classified as meal skipping, based on the recommendation of the Dietary Guidelines for the Brazilian Population. Short sleep duration was determined according to sleep time during the night (≤ 6 hours for those aged ≥18 years and ≤ 7 hours for those under 18 years of age). Associations were estimated using adjusted Poisson regression models.

Results The prevalences of skipping breakfast, lunch, and dinner were of 51.0%, 13.9%, and 35.6% respectively. Short sleep duration was observed in 27.2% of the study population. After adjusting for confounding variables, short sleep duration was positively associated with skipping breakfast (adjusted prevalence ratio [PRadj] = 1.20; 95% confidence interval [95%CI] = 1.08–1.34) and skipping lunch (PRadj = 1.64; 95%CI = 1.27–2.12).

Conclusion University students presented a high prevalence of skipping main meals. Short sleep duration was directly associated with skipping two major meals of the day: breakfast and lunch.

Published: April 2024

This paper reports a novel piezoelectric quartz crystal pressure sensor with a double-ended tuning fork (DETF) resonator. The key design is the resonator beams with a continuously variable section shape. Different from the traditional DETF with straight beams or the one with variable sections with steps, this design can improve sensitivity effectively. Theoretical analysis indicates that the sensitivity will increase with a decrease in beam width. Resonant pressure sensors with three different DETFs are designed and analyzed by finite element analysis software. Simulation results show that the sensitivity of this design is 162.27 Hz/MPa. This sensor has a typical structure, which includes three parts: the diaphragm, DETF resonator, and back-cavity structure. Quartz MEMS processes have been used in fabrication. The three parts are bonded together by vacuum glass frit sealing process. Test results of this sensor show that the natural frequency is 44.709 kHz with a quality factor of 12 717. The sensitivity is 155.6 Hz/MPa in the pressure range of 0–20 MPa. The results indicate that this novel design has advantages in sensitivity and fabrication processes. It will be a benefit for a high-performance and low-cost pressure measurement.

Authors: Wang Dihui , Ban Heng , Jiang Puqing
Published: April 2024

While high-throughput (HT) computations have streamlined the discovery of promising new materials, experimental characterization remains challenging and time-consuming. One significant bottleneck is the lack of an HT thermal characterization technique capable of analyzing advanced materials exhibiting varying surface roughness and in-plane anisotropy. To tackle these challenges, we introduce spatially resolved lock-in micro-thermography, an innovative technique enhanced by tensor analysis for optical thermal characterization. Our comprehensive analysis and experimental findings showcase notable advancements: We present a novel tensor-based methodology that surpasses the limitations of vector-based analysis prevalent in existing techniques, significantly enhancing the characterization of arbitrary in-plane anisotropic thermal conductivity tensors. On the instrumental side, we introduce a straightforward camera-based detection system that, when combined with the tensor-based methodology, enables HT thermal measurements. This technique requires minimal sample preparation and enables the determination of the entire in-plane thermal conductivity tensor with a single data acquisition lasting under 40 s, demonstrating a time efficiency over 90 times superior to state-of-the-art HT thermology. Additionally, our method accommodates millimeter-sized samples with poor surface finish, tolerating surface roughness up to 3.5 μm. These features highlight an innovative approach to realizing HT and accurate thermal characterization across various research areas and real-world applications.
