Numerical Analysis of the Influence of Block-Stone Embankment Filling Height on the Water, Temperature, and Deformation Distributions of Subgrade in Permafrost Regions
Authors: Shan Wei , Ma Min , Guo Ying , Zhang Chengcheng
Published: April 2022

The hydrologic and thermal states of foundation soils have an important influence on subgrade stability in degrading permafrost regions. However, thawing settlement remains a problem in the permafrost regions of Northeast China, because there are few relevant research results in this area, and the foundation deformation mechanism caused by the hydrologic and thermal changes of foundation soils is not clear. Therefore, a subgrade structure with large block stones as embankment filler was proposed to improve the foundation thawing settlement, and it has been successfully implemented in the road project (Yiershi–Chaiqiao section of 308 Provincial Highway) in Inner Mongolia Autonomous Region. To study the action mechanism of this structure on the subgrade deformation, a numerical model of the hydro–thermal–mechanical interaction process in unsaturated frozen soil was established, and the calculation of the water content, temperature, and deformation conditions of the subgrade within 20 years of the highway were carried out. The results show that the embankment block-stone layer can reduce the total heat of the deep foundation, and reduce the migration of unfrozen water from the deep foundation to the active layer. It can also increase the hydrologic and thermal convective flux inside and outside the block-stone layer, thus raising the permafrost table and reducing the subgrade deformation. The block-stone layer thickness has an important influence on the subgrade stability. By comparing the hydrologic, thermal change, and deformation of the block-stone structures with different thicknesses (5.0 m, 4.0 m, 3.5 m, 3.0 m, and 2.0 m), we found that when the thickness of the block-stone layer is 4.0 m, the subgrade stability is the best. In this case, the maximum uneven settlement and the maximum transverse deformation difference of the top surface of the subgrade are +0.521 cm and +0.462 cm, respectively. The subgrade stability is less optimal when the block-stone layer thickness is greater or less than 4.0 m. Thus, there exists an optimal embankment filling height related to the hydrologic and thermal conditions of the foundation soils. This study helps to elucidate the effect of unfrozen water content change on subgrade deformation during permafrost degradation and provides an important reference for solving the problem of thawing settlement of subgrade in permafrost regions.

Photocatalysis is an effective advanced oxidation process to mineralize recalcitrant contaminants in aqueous media. TiO2 is the most used photocatalyst in this type of process. To improve the deficiencies of this material, one of the most used strategies has been to dope TiO2 with metallic ions. Chemical reagents are often used as dopant precursors. However, due to the depletion of natural resources, in this work it was proposed to substitute chemical reagents and instead use a metallic residue (door key) as a doping precursor. The materials were synthesized using the sol–gel method and calcined at 400 °C to obtain the crystal structure of anatase. The characterization of the materials was carried out using X-ray diffraction (XRD), transmission electron microscopy (TEM), diffuse reflectance spectroscopy (DRS), scanning electron microscopy–energy-dispersive X-ray analysis (SEM-EDX) methods X-ray photoelectron spectroscopy (XPS), and inductively coupled plasma optical emission spectroscopy (ICP-OES). The results obtained indicate that Cu+/Cu2+ and Zn2+ ions coexist in the support, which modifies the physicochemical properties of TiO2 and improves its photocatalytic efficiency. The synergistic effect of the dopants in TiO2 allowed the mineralization of diclofenac in an aqueous medium when T-DK (1.0) was used as photocatalyst and simulated solar radiation as an activation source.
Remaining in School in Rural China: Social Capital and Academic Self-Efficacy
Authors: Jordan Lucy P. , Zhou Xiaochen , Fang Lue , Wu Qiaobing , Ren Qiang
Published: April 2022

Despite the significant economic and social transformation, students from rural China continue to remain at significant risk of early school leaving. Little research has addressed the jointly protective roles of family and school resources as well as children’s sense of capability that may increase the likelihood of remaining in school. Data are drawn from the first two waves of a national probability sample of the China Family Panel Studies (CFPS) collected in 2010 and 2012, including households with youth aged 10–15 in 2010 living in rural areas (n = 1503). The results of logistic regression models predicting the likelihood of remaining in school during transition phases of secondary schooling highlight the importance of academic self-efficacy and social capital generated through youth peer networks. Given the severe negative consequences of not finishing secondary school for young people, especially during the later stage of economic transition unfolding in China, findings from this study contribute to an enhanced understanding of the “pull” factors that avert early school leaving. The study offers insight into the design of future low-cost targeted intervention strategies in rural China which could be applied to other middle-income countries.

Published: April 2022

Objective and Impact Statement
. To develop an approach for individualized closed-loop feedback control of microbubble cavitation to achieve safe and effective focused ultrasound in combination with microbubble-induced blood-brain barrier opening (FUS-BBBO).
Introduction
. FUS-BBBO is a promising strategy for noninvasive and localized brain drug delivery with a growing number of clinical studies currently ongoing. Real-time cavitation monitoring and feedback control are critical to achieving safe and effective FUS-BBBO. However, feedback control algorithms used in the past were either open-loop or without consideration of baseline cavitation level difference among subjects.
Methods
. This study performed feedback-controlled FUS-BBBO by defining the target cavitation level based on the baseline stable cavitation level of an individual subject with “dummy” FUS sonication. The dummy FUS sonication applied FUS with a low acoustic pressure for a short duration in the presence of microbubbles to define the baseline stable cavitation level that took into consideration of individual differences in the detected cavitation emissions. FUS-BBBO was then achieved through two sonication phases: ramping-up phase to reach the target cavitation level and maintaining phase to control the stable cavitation level at the target cavitation level.
Results
. Evaluations performed in wild-type mice demonstrated that this approach achieved effective and safe trans-BBB delivery of a model drug. The drug delivery efficiency increased as the target cavitation level increased from 0.5 dB to 2 dB without causing vascular damage. Increasing the target cavitation level to 3 dB and 4 dB increased the probability of tissue damage.
Conclusions
. Safe and effective brain drug delivery was achieved using the individualized closed-loop feedback-controlled FUS-BBBO.

Authors: Ovchinnikova A.V. , Zimin S.D.
Published: April 2022

The study is devoted to topical issues of development of enterprises of the military-industrial complex of the Russian Federation, which at the present stage have a high innovative potential, their interaction with small businesses to improve production efficiency. The ecosystem approach makes it possible to form new principles of integration that replace the classical forms of cooperation: contracting, institutionalization and clustering. The objects of the study were enterprises of the military-industrial complex, development institutions, business entities of the Udmurt Republic. The aim of the work is to develop a mechanism for "drawing" SMEs into the production ecosystem of a technological large defense complex business to ensure maximum efficiency of all participants in the production process. To substantiate the possibility of using the ecosystem approach as a mechanism for integrating defense industry enterprises and small businesses, the system method was used in the work (when deriving the composition of ecosystems, characterizing the components of the ecosystem, describing the presence and dynamics of links between the components), as well as the modeling method (when developing the involvement mechanism). To solve this problem, the authors have developed models of a regional accelerator of business ideas, technology transfer, a regional entrepreneurial production ecosystem as tools for innovative growth and development of enterprises in the military-industrial complex. The results obtained are consistent with domestic and foreign experience in the development of high-tech large industrial business, and therefore can be applied in the implementation of the regional economic growth policy, as well as defense industry enterprises on the way to further diversification.
Massive windfalls boost an ongoing spruce bark beetle outbreak in the Southern Alps
Authors: Nardi Davide , Finozzi Valerio , Battisti Andrea
Published: April 2022

European coniferous forests are currently threatened by bark beetles (e.g. Ips typographus) because of an increasing incidence of triggering factors, such as drought and windstorms. Furthermore, such natural disturbances are expected to increase in terms of magnitude and frequency due to climate change, and thus interacting with each other. Here, we present a particular case study in the Southern Italian Alps (Gares, Canale d’Agordo, Belluno), in which wind disturbance interacts with an ongoing outbreak of I. typographus, probably associated with an extended drought in the previous three years. By combining remote sensing and field surveys, we spatially reconstructed the bark beetle attack in the period 2015-2021, which includes the Vaia windstorm in October 2018. Although the windstorm occurred in an expanding phase of the bark beetle outbreak, attacks on standing trees did not occur during the first year after the windstorm but were observed two years later. Our findings suggest that an overlap of a large availability of wind felled trees with an incipient outbreak of I. typographus resulted in an immediate decrease of standing trees mortality in the year following the storm. However, the fallen trees worked as a hidden sink for the beetle population, which in the following years massively attacked the standing trees that survived the storm.

In this article, we present some results concerning the harmonicity on the tangent bundle equipped with the vertical rescaled metric. We establish necessary and sufficient conditions under which a vector field is harmonic with respect to the vertical rescaled metric and we construct some examples of harmonic vector fields. We also study the harmonicity of a vector field along with a map between Riemannian manifolds, the target manifold is equipped with a vertical rescaled metric on its tangent bundle. Next we also discuss the harmonicity of the composition of the projection map of the tangent bundle of a Riemannian manifold with a map from this manifold into another Riemannian manifold, the source manifold being whose tangent bundle is endowed with a vertical rescaled metric. Finally, we study the harmonicity of the tangent map also the harmonicity of the identity map of the tangent bundle.

Perspective on Wildgrass Oil & Gas Committee v. Colorado Oil & Gas Conservation Commission and the Embracing of Associated Standing
Authors: Cantafio Ralph A. , Nowak Miles C. , Watson Cody J.
Published: April 2022

The ongoing litigations between the Wildgrass Oil & Gas Committee (“Wildgrass”) and, among others, the Colorado Oil & Gas Conservation Commission (“COGCC”) serve as a microcosm of the political and legal horizons that define the microscope used to examine Colorado oil and gas development. This set of litigations began administratively with the application for permits before the COGCC and, over the passage of time, weaved its way through the District Court of the City and County of Denver (the “State District Court”), the United States District Court for the District of Colorado (the “Federal District Court”), the Colorado Court of Appeals (the “Court of Appeals”), and finally the United States Court of Appeals for the 10th Circuit (the “10th Circuit”). As of the time of this writing, the State District Court action remains currently unresolved since the Court of Appeals remanded the case. This Article will provide an overview of these litigations and the Authors’ thoughts and insights as to the political and regulatory environment of these judicial decisions, including an emphasis on associated standing by the Court of Appeals.

Effect of Vitamin D Supplementation on Risk of Fractures and Falls According to Dosage and Interval: A Meta-Analysis
Authors: Kong Sung Hye , Jang Han Na , Kim Jung Hee , Kim Sang Wan , Shin Chan Soo
Published: April 2022

Background: Although recent studies comparing various dosages and intervals of vitamin D supplementation have been published, it is yet to be elucidated whether there is an appropriate dose or interval to provide benefit regarding fracture risk. We aimed to assess the published evidence available to date regarding the putative beneficial effects of vitamin D supplements on fractures and falls according to various dosages and intervals.Methods: We performed a meta-analysis of randomized controlled studies reporting associations between vitamin D supplementation and the risks of fractures and falls in PubMed, EMBASE, and Cochrane library. Studies with supplements of ergocalciferol or calcitriol, those with a number of event ≤10, or those with a follow-up duration of less than 6 months were also excluded.Results: Thirty-two studies were included in the final analysis. Vitamin D supplementation with daily dose of 800 to 1,000 mg was associated with lower risks of osteoporotic fracture and fall (pooled relative risk [RR], 0.87; 95% confidence interval [CI], 0.78 to 0.97 and RR, 0.91; 95% CI, 0.85 to 0.98), while studies with <800 or >1,000 mg/day did not. Also, among intervals, daily administration of vitamin D was associated with the reduced risk of falls, while intermittent dose was not. Also, patients with vitamin D deficiency showed a significant risk reduction of falls after vitamin D supplementation.Conclusion: Daily vitamin D dose of 800 to 1,000 IU was the most probable way to reduce the fracture and fall risk. Further studies designed with various regimens and targeted vitamin D levels are required to elucidate the benefits of vitamin D supplements.

Interplay between Young Stars and Molecular Clouds in the Ophiuchus Star-forming Complex
Authors: Gupta Aashish , Chen Wen-Ping
Published: April 2022

We present spatial and kinematic correlation between the young stellar population and the cloud clumps in the Ophiuchus star-forming region. The stellar sample consists of known young objects at various evolutionary stages, taken from the literature, some of which are diagnosed with Gaia EDR3 parallax and proper-motion measurements. The molecular gas is traced by the 850 μm Submillimetre Common-User Bolometer Array-2 image, reaching ∼2.3 mJy beam−1, the deepest so far for the region, stacked from the James Clerk Maxwell Telescope/Transient program aiming to detect submillimeter outburst events. Our analysis indicates that the more evolved sources, namely the class II and III young stars, are located further away from clouds than class I and flat-spectrum sources that have ample circumstellar matter and are closely associated with natal clouds. Particularly the class II and III population is found to exhibit a structured spatial distribution indicative of passage of shock fronts from the nearby Sco–Cen OB association thereby compressing clouds to trigger star formation, with the latest starbirth episode occurring now in the densest cloud filaments. The young stars at all evolutionary stages share similar kinematics. This suggests that the stellar patterns trace the relics of parental cloud filaments that now have been dispersed.

Published: April 2022

INTRODUCTION: Stunting is one priority for nutritional and health problems in Indonesia.

AIM: This research was action research aimed at improving the nutritional status of the community, especially in supporting stunting reduction programs through specific nutrition interventions using local functional foods and determine, whether the program can be implemented in a proper setting.

METHODS: The research was conducted in the working area of Tempel 2 Public Health Center (PHC Tempel 2), Sleman Regency, DI Yogyakarta using an action research approach. This study was involved 26 children aged 12–59 months who were living in the PHC Tempel 2, Sleman, Yogyakarta Special District Province. This product was given every day for 3 months with a daily dosage of 100 mL/day. The consumption was monitored using food diary to identify the compliance rate of the products.

RESULTS: The consumption of INTAKE significantly increased the growth of the subjects which included height (91.94 vs. 95.13 cm), weight (12.75 vs. 13.63 kg), and nutritional status of height for age z-score (−1.348 vs. −0.933) 3 months after the intervention.

DISCUSSION: Although several factors such as eating behavior can affect the nutritional status of children, the INTAKE intervention can provide an alternative food supplement for children besides the programs that have been provided by the government.

CONCLUSION: The provision of fermented milk with iron-zinc fortification (INTAKE) had a positive intake for the growth of children under 5 years old. The intervention was feasible to be carried out over a longer period. However, considering the nutrition-related behaviors of the children, it should be considered administering different supplementary food while maintaining consistent nutrition education to enhance the success of the programs. Collaboration between academicians, health offices, and industry also proposed a good impact.

Published: April 2022

Aim: Iron deficiency anemia (IDA) is the most common cause of anemia in the Kingdom of Saudi Arabia. Thalassemia and sickle cell disease (SCD) are major concerns in several nations, including KSA. This study sought to investigate the prevalence of IDA, sickle cell trait (SCT), and B thalassemia trait (BTT) among school children in Al-Khobar and Makkah, Saudi Arabia.
Methods: A multistage random sample of 570 school children aged 12–18 years from both cities were educated about these illnesses and tested for CBC, serum iron, TIBC, reticulocytosis, and sickling. In some circumstances, hemoglobin electrophoresis and HPLC were used.
Results: Overall, 13% of people had IDA, 3.2 percent had SCT, and 2.5 percent had BTT. The hematological parameters of students with IDA and BTT differed significantly from those of normal students in each city, but not between normal students and those with SCT. There were no significant differences between the sexes for all blood parameters except iron and TIBC.
Conclusion: Strengthening public health education, dietary initiatives, and school-based hemoglobinopathy carrier screening is proposed to help detect anemia early.

Il analyse la contribution des employeuses à la création de ce droit. Les employeuses mobilisées dans les premières associations de maîtres et maîtresses de maison participent activement à l’encadrement juridique des relations de travail et à la création des premiers droits conventionnels pour les employées de maison, en même temps qu’elles obtiennent pour elles-mêmes un statut d’employeuse. Cet engagement leur permet de sortir du foyer et d’investir des domaines de la sphère publique dont elles étaient jusque-là exclues, tout en se conformant à l’ordre social de leur milieu.
Résister dans un environnement contraint

Published: April 2022

Au Liban, l’emploi de travailleuses domestiques immigrées est un phénomène de grande ampleur encadré par le système migratoire de la kafala , actant l’instabilité et la vulnérabilité des travailleurs étrangers. Les contraintes structurelles et sociales interrogent les possibilités de regroupements et d’actions collectives de femmes isolées par le travail domestique. L’article propose d’analyser les processus de résistances initiés par ces travailleuses. Sur le mode de pratiques quotidiennes de lutte pour leur survie, les travailleuses parviennent à se rendre visibles et bénéficient des opportunités ouvertes par certains espaces pour se regrouper. Toutefois, dans un contexte contraint, l’action collective est dépendante des organisations non gouvernementales (ONG). Les mobilisations collectives lancées par les travailleuses restent sur un mode dormant, en gagnant en influence sur le terrain sans toutefois pouvoir éclore ouvertement sur la scène publique.
L’art, le cinéma et le public : généalogie de l’aura
Authors: Susca Vincenzo
Published: April 2022

Dans le socle de l’interprétation benjaminienne de l’aura d’une œuvre d’art en tant que dispositif magique par lequel se rend présente une absence, nous suggérons que le processus de reproductibilité technique sollicite des mécanismes sociaux d’appropriation des formes communicatives, dans lesquels l’aura a un rôle central. À la disparition de la valeur culturelle, politique et sacrée d’une œuvre authentique et non reproductible s’oppose la formation d’une chaîne d’instruments, d’objets et d’images à haute densité symbolico-émotionnelle qui rendent le corps social même et ses conformations, sujet et objet de la contemplation. Le cinéma devient la scène médiatique, le territoire où s’inaugure un processus de va-et-vient entre l’œuvre et le public, objet et sujet de la communication et de la culture. Ainsi, dans les méandres auparavant occupés par l’art, s’engage la longue dynamique du devenir art du public.

Effective science learning can be achieved when lab experiments become a central part of science curriculum. However, science learning in most rural schools is restrained by the deficiency of conventional lab equipment. From this viewpoint, it was imperative to explore alternative lab environments where learners can conduct the required experiments. This study investigated teachers' experiences in using the Virtual Lab to teach science. Particularly, this study is guided by the research question: What are science teachers' pedagogical and technological experiences in using the Virtual Lab to mediate science learning through scientific experiments? The findings are based on the individual teachers’ and combined experiences on the use of Virtual Lab. Data was collected through semi-structured interviews, lesson observations and journal reflections. The results reveal that the Virtual Lab has several benefits. It also indicated some shortcomings of the Virtual Lab. Nevertheless, the findings suggest the Virtual Lab is well-suited to be used as alternative to the conventional Lab

Published: April 2022

The delivery of medical education is a complex process, wherein we aim toward not only the acquisition of desired knowledge and skills, but also creating a system and cadre of healthcare personnel who possess the traits of being professional, leader, team-worker, and a lifelong learner. Self-directed learning (SDL) has been regarded as an important aspect of lifelong learning and is one of the core competencies expected of a medical graduate. Most of the regulatory bodies across the globe strongly advocate for the inclusion of SDL activities within the medical school curriculum. The overall process of implementation and faculty training can be supervised by the Medical Education Unit of the institution, along with the members of the Curriculum Committee and phase-wise faculty members. In conclusion, SDL is an essential attribute to ensure lifelong learning among medical students. Considering the wide range of benefits associated with SDL, it is crucial that all the steps are planned and implemented in a systematic manner to enable successful implementation.

The participants had a mean age of 18.1 ± 9.85 years, and 64 (56.6%) of them were males. Seven (6.2%) of the participants had PHTN as determined by a TRVmax of ≥2.5 m/s. PHTN was significantly associated with age, sex, body mass index (BMI), blood pressure, oxygen saturation, and serum creatinine.

Conclusion:

PHTN remains common among patients with SCD and it is associated with female gender, increasing age, a rising BMI, blood pressure and serum creatinine, and a decreasing oxygen saturation and hematocrit. We recommend regular screening of patients with SCD for PHTN and that these associated factors should be taken into consideration when screening SCD patients for PHTN.

Myths and truths about varicose veins
Authors: Yang Shin-Seok , Kim Suh Min
Published: April 2022

Background: Varicose veins are a common chronic venous disorder that leads to a significantly reduced quality of life and high healthcare resource burden. There is a large amount of research-based data and opinions regarding varicose veins. There are also some common myths and misconceptions about the treatment options.Current Concepts: Management options include compression therapy, open venous surgery, and endovenous therapy. An appropriate treatment option must be selected on a case-by-case basis based on the symptoms, severity, and duplex ultrasonography findings. Venous intervention should be considered if the condition is symptomatic and often, there is no need for urgent surgery or endovenous therapy because the symptoms usually progress slowly and severe cardiac problems are rare. According to previous studies, there is no difference between the endovenous therapy modalities and the traditional surgical method (i.e., high ligation and stripping) in terms of recurrence rates. Therefore, case-specific factors, such as anatomy and economic factors, should be considered. When compression therapy is considered, graduated compression stocking with suitable pressure should be prescribed. Venoactive drugs can be suggested in addition to compression therapy for symptomatic varicose veins or venous ulcers.Discussion and Conclusion:. Correct information regarding treatment for varicose veins based on the best available evidence must be provided to patients. The treatment options for varicose veins should be selected on a case-by-case basis considering the patient`s symptoms, anatomy and economic factors.
