Line-focus solar concentration 10 times higher than the 2D thermodynamic limit
Authors: Johnsen Håkon J. D. , Miñano Juan C. , Torgersen Jan
Published: May 2022

Line-focus solar concentrators have traditionally been limited by the 2D concentration limit due to the continuous translational symmetry in these systems. This limit is orders of magnitude lower than the 3D limit, severely limiting the achievable concentration ratio compared to point-focus systems. We propose a design principle for line-focus solar concentrators that bypasses this 2D limit, while maintaining a trough-like configuration and only requiring single-axis external solar tracking. This is achieved by combining the concept of étendue squeezing with the concept of tracking integration. To demonstrate the principle, we present a design example that achieves a simulated average yearly efficiency of 80% at a geometric concentration of 335x under light with a ±9mrad angular distribution and horizontal single-axis external tracking. We also show how the same design principle can achieve a line-focus with 1563x geometric concentration at 90% efficiency if design constraints are relaxed by foregoing tracking-integration and assuming two-axis external solar tracking. This design principle opens up the design space for high-concentration line-focus solar concentrators, and may contribute to a reconsideration of the trade-off between concentration and acceptance angle in such systems.

Published: May 2022

When a near-eye display (NED) device reproduces an image at a location close to the eye, the virtual image is implemented at a large angle. The uniformity of the image is unbalanced due to the change in diffraction efficiency by the hologram recording angle and angular selectivity. This study proposes a method for implementing an optimal uniform image by analyzing the diffraction efficiency and the reconstructed image was analyzed using angular selectivity generated while reproducing the source point of the diffused image as an intermediate element by holographic optical element (HOE). This research provides practical results for displaying high diffraction efficiency and immersive holographic images in the NED system with HOE as uniformed intermediate elements.
How to estimate health service coverage in 58 districts of Benin with no survey data: Using hybrid estimation to fill the gaps
Authors: Ocampo Alex , Valadez Joseph J. , Hedt-Gauthier Bethany , Pagano Marcello
Published: May 2022

The global movement to use routine information for managing health systems to achieve the Sustainable Development Goals, relies on administrative data which have inherent biases when used to estimate coverage with health services. Health policies and interventions planned with incorrect information can have detrimental impacts on communities. Statistical inferences using administrative data can be improved when they are combined with random probability survey data. Sometimes, survey data are only available for some districts. We present new methods for extending combined estimation techniques to all districts by combining additional data sources. Our study uses data from a probability survey (n = 1786) conducted during 2015 in 19 of Benin’s 77 communes and administrative count data from all of them for a national immunization day (n = 2,792,803). Communes are equivalent to districts. We extend combined-data estimation from 19 to 77 communes by estimating denominators using the survey data and then building a statistical model using population estimates from different sources to estimate denominators in adjacent districts. By dividing administrative numerators by the model-estimated denominators we obtain extrapolated hybrid prevalence estimates. Framing the problem in the Bayesian paradigm guarantees estimated prevalence rates fall within the appropriate ranges and conveniently incorporates a sensitivity analysis. Our new methodology, estimated Benin’s polio vaccination rates for 77 communes. We leveraged probability survey data from 19 communes to formulate estimates for the 58 communes with administrative data alone; polio vaccination coverage estimates in the 58 communes decreased to ranges consistent with those from the probability surveys (87%, standard deviation = 0.09) and more credible than the administrative estimates. Combining probability survey and administrative data can be extended beyond the districts in which both are collected to estimate coverage in an entire catchment area. These more accurate results will better inform health policy-making and intervention planning to reduce waste and improve health in communities.
The seasonality of infections in tropical Far North Queensland, Australia: A 21-year retrospective evaluation of the seasonal patterns of six endemic pathogens

Published: May 2022

An understanding of the seasonality of infections informs public health strategies and assists clinicians in their management of patients with undifferentiated illness. The seasonality of infections is driven by a variety of environmental and human factors; however, the role of individual climatic factors has garnered much attention. This study utilises Poisson regression models to assess the seasonality of six important infections in tropical Australia and their association with climatic factors and severe weather events over a 21-year period. Melioidosis and leptospirosis showed marked wet season predominance, while more cases of rickettsial disease and cryptococcosis were seen in cooler, drier months.Staphylococcus aureusinfections were not seasonal, while influenza demonstrated inter-seasonality. The climate did not significantly change during the 21 years of the study period, but the incidence of melioidosis and rickettsial disease increased considerably, highlighting the primacy of other factors—including societal inequality, and the impact of urban expansion—in the incidence of these infections. While anthropogenic climate change poses a threat to the region—and may influence the burden of these infections in the future—this study highlights the fact that, even for seasonal diseases, other factors presently have a greater effect on disease incidence. Public health strategies must also target these broader drivers of infection if they are to be effective.
Computational analysis of missense filamin-A variants, including the novel p.Arg484Gln variant of two brothers with periventricular nodular heterotopia
Authors: Gerlevik Umut , Saygı Ceren , Cangül Hakan , Kutlu Aslı , Çaralan Erdal Fırat , Topçu Yasemin , Özören Nesrin , Sezerman Osman Uğur
Published: May 2022

Background

Periventricular nodular heterotopia (PNH) is a cell migration disorder associated with mutations in Filamin-A (FLNA) gene on chromosome X. Majority of the individuals with PNH-associatedFLNAmutations are female whereas liveborn males withFLNAmutations are very rare. Fetal viability of the males seems to depend on the severity of the variant. Splicing or severe truncations presumed loss of function of the protein product, lead to male lethality and only partial-loss-of-function variants are reported in surviving males. Those variants mostly manifest milder clinical phenotypes in females and thus avoid detection of the disease in females.

Methods

We describe a novel p.Arg484Gln variant in theFLNAgene by performing whole exome analysis on the index case, his one affected brother and his healthy non-consanguineous parents. The transmission of PNH from a clinically asymptomatic mother to two sons is reported in a fully penetrant classical X-linked dominant mode. The variant was verified via Sanger sequencing. Additionally, we investigated the impact of missense mutations reported in affected males on the FLNa protein structure, dynamics and interactions by performing molecular dynamics (MD) simulations to examine the disease etiology and possible compensative mechanisms allowing survival of the males.

Results

We observed that p.Arg484Gln disrupts the FLNa by altering its structural and dynamical properties including the flexibility of certain regions, interactions within the protein, and conformational landscape of FLNa. However, these impacts existed for only a part the MD trajectories and highly similar patterns observed in the other 12 mutations reported in the liveborn males validated this mechanism.

Conclusion

It is concluded that the variants seen in the liveborn males result in transient pathogenic effects, rather than persistent impairments. By this way, the protein could retain its function occasionally and results in the survival of the males besides causing the disease.
Attitudes and acceptability of children, caregivers, and healthcare providers about using telemedicine for pediatric HIV care in a resource-limited setting

Published: May 2022

Background

The Pediatric HIV Telemedicine Initiative is a video-linked delivery of expert services, designed to reach those previously unable to access expert HIV care. The present qualitative study was designed to understand the acceptability of telemedicine [TM] by patients, their caregivers and health care providers in the anti-retroviral therapy (ART) centers in Maharashtra.

Methods

We conducted focus group discussions with caregivers at six ART centres (three linked with TM facilities and three not linked with TM). We also conducted in-depth interviews with medical officers, counselors, and pharmacists at each centre. The data from the interviews were transcribed and translated into English for analysis. The qualitative data were analyzed using thematic framework approach.

Results

Children and caregivers who had participated in telemedicine consultation through video conference found the process acceptable, were comfortable communicating during these sessions, and did not have any specific problem to report. The advantages of TM were: consultation without having to travel to other cities; economic advantage; and prompt consultation. The total time spent during the process and technical difficulties during the TM sessions were some of the challenges. The medical officers had the opportunity to discuss difficult cases with the expert during the TM session. Some sessions were also considered a ’group counseling’ session, wherein several children and caregivers were able to interact and learn from each other and motivate each other. The health care providers at the three centers that did not currently have TM facilities expressed a desire to have these services at their centers as well. According to them, these facilities will help them address complicated and difficult pediatric HIV cases. Currently, they send their patients to referral centers or other hospitals. Since, many of these referral hospitals are situated in bigger cities, less than 50% of patients access care at these centers This is mostly due to the time constraints and finances (travel/stay) required for accessing these centres.

Discussion

TM was a feasible, acceptable, and desired approach for care of children living with HIV/AIDS. It provides support to their caregivers as well as their care providers. The ART staff from the telemedicine-linked peripheral centers were supportive of the use of TM and wanted these services to be initiated in the non-linked centers.
Combined nerve and vascular ultrasound in thoracic outlet syndrome: A sensitive method in identifying the site of neurovascular compression
Authors: Dollinger Peter , Böhm Josef , Arányi Zsuzsanna
Published: May 2022

We investigated the diagnostic utility of combined nerve and vascular ultrasound in thoracic outlet syndrome (TOS) in a retrospective cohort study on two sites, involving 167 consecutive patients with the clinical symptoms suggestive of neurogenic and/or vascular TOS, and an age- and sex-matched control group. All patients and control subjects underwent nerve ultrasound of the supraclavicular brachial plexus to look for fibromuscular anomalies / compression of the brachial plexus in the scalenic region, and vascular ultrasound of the infraclavicular subclavian artery with the arm in neutral and abducted position, serving as an indicator for costoclavicular compression of the neurovascular bundle. Based on clinical symptoms, neurogenic TOS (81%) was the most frequent type of TOS, followed by combined neurogenic and arterial TOS (8%). The frequency of abnormal nerve and/or vascular ultrasound findings differed significantly from the control group (P<0.00001). The pooled sensitivity was 48% for nerve ultrasound, 85% for vascular ultrasound, and 94% when combined. Among the findings, the fibromuscular ‘wedge-sickle sign’, indicating compression of the lower trunk in the scalenic region by a congenital fibromuscular anomaly (e.g. Roos ligaments), showed the highest specificity (100%). A bony ‘wedge-sickle sign’ was also delineated, where lower trunk compression is caused by the neck of the 1st rib. As implied by the higher sensitivity of vascular ultrasound, the most common site of compression was the costoclavicular space, but multilevel compression was also frequently observed. In summary, combined nerve and vascular ultrasound is a sensitive and reliable method to support the diagnosis of TOS. It can also identify the site(s) of compression, with obvious therapeutic consequences.
Representation of sustainability in US men’s fashion magazines: A content analysis based exploratory study
Authors: Li Jitong
Published: May 2022

This exploratory study aims to investigate the representation of sustainability in US men’s fashion magazines. Specifically, employing quantitative and qualitative content analysis, this study identifies and analyses meanings of sustainability, the companies having sustainable practices, the products with sustainable attributes and specific sustainable practices. 41 and seventeen articles related to fashion and sustainability were collected from the two US online men’s fashion magazines, Gentlemen’s Quarterly (GQ) and Esquire, respectively. For both magazines, the environmental dimension is more frequently addressed than the social dimension in the articles. Various terms are used to describe the same subject and the two magazines have different preferences when selecting words to present the same issue. For example, GQ prefers ‘eco-friendly’, but Esquire picks ‘planet’ when discussing the environmental dimension. Moreover, the concept of sustainability is ambiguous in the two magazines due to overlapped terms and lack of explanation. In both magazines, the most frequently mentioned product is footwear. However, GQ tends to introduce sustainable practices concerning solid waste and focus on the luxury sector. Comparably, Esquire focuses more on the environmental impacts of raw material sourcing and the affordable fashion sector. This study contributes to the body knowledge of sustainability communication in the men’s fashion sector. Researchers can employ the results to conduct further analysis, such as examining the difference between sustainability representation in magazines and academic studies. Based on the results, companies should improve their communication with consumers regarding their sustainable practices.

Dazwischen: Ich
Authors: Beck Laura
Published: May 2022

Laura Beck widmet sich in diesem Beitrag der Verhandlung von Alteritäts- und Adoleszenzerfahrungen in Julya Rabinowichs Jugendroman »Dazwischen: Ich« (2016), in dem diese ein ganzes Panorama an ,Alteritäten' auffächere. Die Migrationserfahrung der jugendlichen Ich-Erzählerin sei nicht nur durch ,kulturelle Differenz', sondern ebenfalls durch eine Vielzahl an miteinander verschränkten körperlichen, psychischen, sprachlichen und räumlichen Grenzüberschreitungen bedingt. Diese würden u.a. durch Rückgriff auf Raummetaphern und literarische Intertexte ausgestaltet. Der Beitrag zeigt, wie »Dazwischen: Ich« gegen eine Vorstellung von ,Identitäten' arbeitet, die sich nur in Abhängigkeit von monolithischen Kulturkonzepten herausbilden. Beck stellt jedoch auch heraus, dass die Fokussierung des Textes auf ,Überkulturelles' Gefahr läuft, Widerständiges an den Rand zu drängen.

Gender und christliche Mission
Authors: Rempfer Dorothee
Published: May 2022

Die christliche Mission war in mehrfacher Hinsicht ein geschlechterspezifisches Unternehmen, in dem Frauen und Männern klar definierte Rollen und Räume zugewiesen waren. Doch das fest umrissene Geschlechterbild stieß in der Praxis an Grenzen. So forderte die Bevölkerung in Namibia und Sumatra die Vorstellungen heraus und erzwang Veränderungen. Anhand ausgewählter Beispiele entfaltet Dorothee Rempfer die Dynamiken von Aneignung und Ablehnung religiös fundierter Geschlechterverhältnisse. Damit liefert sie wichtige Erkenntnisse zu Handlungsspielräumen und Gestaltungsmöglichkeiten europäischer und nichteuropäischer Akteur*innen im Kontext von Gender und Kolonialismus.
Meandering Feuilleton Essay about two concerts that I did not see. Or: About how I read Hall, Mignolo and Walsh instead because I want to write an article for an anthology on Decolonizing Arts and think about whether it is possible to decolonialize Popular Music
Authors: Ismaiel-Wendt Johannes Salim
Published: May 2022

Johannes Salim Ismaiel-Wendt's contribution aims to convey his uneasiness with an overly direct application of the concept »decolonizing« in the context of Popular Music. Along Ariana Grandes song »Dangerous Woman« (2016) and against the background of a bombing at one of her concerts in 2017, the contribution shows how difficult or impossible it can be to locate a point of entry, from which Popular Music is to be decolonialized. Ismaiel-Wendt likes to stress, that decolonialization strategies and decolonial knowledge are not only generated outside of Popular Music; for example, (again mainly) in discursive and theoretical or alleged institutional scholarly criticism. Decolonialization strategies and decolonial knowledge are generated inside of Popular Music too.
Buried in the Colonial Graveyard? Indigenous Sound Ontologies, Repatriation and the Ethics of Curating Ethnographic Sounds
Authors: Fuhr Michael , Lewy Matthias
Published: May 2022

In this article, Michael Fuhr and Matthias Lewy discuss the potentials and challenges of dealing with and exhibiting sounds and sound concepts of indigenous peoples and ask if and how ethnographically-informed sound curation can help 'decolonize' the museum. Drawing on historical recordings of the Selk'nam, Yagán and the Pémon, they show that ethical concerns with the ways of how European institutions handle these recordings are inextricably entwined with unresolved questions of who should possess authority and representational power over the recorded and archived sounds. Acknowledging indigenous sound ontologies can challenge the representational mode in European museum and archival spaces.

Published: May 2022

The carbonized rice husk (CRH) is an agro-industrial residue with great potential for use in mixtures with other substrates for the production of vegetable seedlings. Thus, the purpose of this study was to evaluate the effect of the addition of CRH to the commercial substrate for the production of greenhouse seedlings. The evaluated vegetables were lettuce, broccoli and mustard, cultivated in polystyrene foam (Styrofoam®) trays. Five treatments were evaluated: 100% of the commercial substrate (CS); 25% of CRH + 75% of CS; 50% of CRH + 50% of CS; 75% CRH + 25% CS; and 100% CRH, in a completely randomized design with twelve replicates. The substrates were evaluated for their physical and chemical characteristics. The morphometric evaluations were: number of leaves per plant, plant height, shoot fresh matter yield, root length, and shoot and root dry matter yield. The data were submitted to regression analysis, and the homogeneity of the variance between the experiments was confirmed by the Cochran test. With the addition of CRH to the substrate, there was an increase in total porosity and P content and a reduction in density, water holding capacity, cation exchange capacity, electrical conductivity, and N, K, S, Ca and Mg contents. The carbonized rice husk added to the commercial substrate is a viable alternative for the production of lettuce, broccoli and mustard seedlings. The quality of the vegetable seedlings was higher when there was a 25% CRH + 75% CS mixture.
Determination of the type and the length for the transition curves on the directions of high-speed train operation
Authors: Kurhan Mykola , Kurhan Dmytro , Husak Marina , Hmelevska Nelya
Published: May 2022

In many countries around the world, a cubic parabola is used as transition curves in a simplified form. Today, the properties of many mathematical curves are well studied, which can be used as transition curves. The object of research is the process of restructuring transition curves when organizing high-speed trains operation. The use of modern means of mathematical modelling allows to add a number of dynamic characteristics for evaluation parameters of motion in the curved sections of the tracks. Thus, with an increase in speed for transition curves, both the values of unbalanced acceleration and its change in time, and also the velocity attenuation of oscillations of rolling stock  when moving from a transition curve to a circular curve or to a direct section. On the basis of the conducted research, it has been found that when increasing the speed of the vehicle movement in the range from 120 to 200 km/h, the length of the stabilization section increases at the output of the curvature by an average of 20 m for every 40 km/h. The analysis showed that with correctly set parameters of transition curves, which correspond to the maximum speed of movement and radius of a circular curve, the strength and reliability of the bearing elements in the structure of the permanent way and the travel comfort are fully ensured.
Microplastic Identification in Fisheries Commodities in Sayung Waters, Demak
Authors: Muhammad Fuad , Hadiyanto H. , Alwan Abdurrafi
Published: May 2022

Each year plastic production worldwide has increased. Approximately 10% of the production of plastic will lead to the sea. This plastic is degraded to be a small particle size < 5mm called microplastic. The river is the main route of entry of plastic from land to the sea. Sayung River is a river that has the potential to be contaminated with microplastics around which it is used as a location for the cultivation of various fisheries commodities including Pernaviridis, Penaeus monodon, and Lates calcarifer. The study aims to determine the number and type of microplastic in Penaeus monodon, Pernaviridis, and Lates calcarifer. Samples were taken from three different stations in the coverage area. Microplastic abundance analysis by isolating microplastic on each sample. Isolation samples of Pernaviridis, Penaeus monodon, and Lates calcarifer are done by dissolving the sample in a solution of 10% KOH was allowed for 24 hours at a temperature of 60 oC and observed under a binocular microscope. Founded types of microplastic are fiber, fragments, pellets, and films on Pernaviridis, Penaeus monodon, and Lates calcarifer. Pernaviridis found on many types of films, in Penaeusmonodon are the most prevalent types of fragments and the Lates calcarifer most common types of fiber. Pellet type is the least kind found in Pernaviridis and Penaeus monodon. Based on the age when taken, Penaeus monodon is the commodity that has the most potential to be contaminated with microplastic while based on the number of particles found in Lates calcarifer is the commodity with the most potential to be contaminated with microplastic.

Published: May 2022

High purity insoluble dietary fiber (HPIDF) was extracted from Okara by compound enzyme method, and solid emulsifiers with different particle sizes were prepared by wet grinding. Its composition, structure and physicochemical properties were studied, and the influence mechanism of solid emulsifiers with different particle sizes on emulsifying properties and interface stability of Pickering emulsion was systematically studied. The results showed that the particle size of HPIDF decreased significantly, the ζ-potential, contact Angle and swelling capacity of HPIDF ncrease significantly (p < 0.05). HPIDF forms an adsorption layer at the oil-water interface, and some of them are connected to form a bridge network structure, which plays a role of steric hindrance. And the emulsion has excellent stability under different environmental factors. HPIDF are suitable raw materials as natural food-grade solid emulsifiers. It is cost-effective and eco-friendly to realize the high-value utilization of Okara resources, reduce resource waste, and extend the industrial chain.
The modified Rusanov scheme for solving the phonon-Bose model
Authors: Mohamed Kamel , Abdelrahman Mahmoud A. E.
Published: May 2022

This paper considers the one-dimensional model of heat conduction in solids at low temperature, the so called phonon-Bose model. The nonlinear model consists of a conservation equation for the energy density e and the heat flux Q with ∣Q∣ < e. We present a simple and accurate class of finite volume schemes for numerical simulation of heat flow in arteries. This scheme consists of predictor and corrector steps, the predictor step contains a parameter of control of the numerical diffusion of the scheme, which modulate by using limiter theory and Riemann invariant, the corrector step recovers the balance conservation equation, the scheme can compute the numerical flux corresponding the real state of solution without relying on Riemann problem solvers and it can thus be turned to order 1 in the regions where the flow has a strong variation and to order 2 in the regions where the flow is regular. The numerical test cases demonstrate high resolution of the proposed finite volume scheme (modified Rusanov) and confirm its capability to provide accurate simulations for heat flow under flow regimes with strong shocks.

Objectives

This randomized controlled trial evaluated the stress, anxiety, and burnout of professionals exposed to complementary spiritist therapy (CST), which consists in therapeutic resources as prayer, Spiritist passe, fluidic water and spiritual education or control.

Methods

Seventy-six professionals were randomized to CST or control: to maintain the routine for 5 weeks. The ISSL scale, anxiety and depression Beck’s indices, Maslach instrument, subjective well-being and WHOQOL-BREF were used at baseline and five-week. Blood count and cytokine dosage were collected at baseline, one-week and five-week. Analysis using the intention to treat approach.

Results

The means of variation of stress (exhaustion phase) between baseline and five-week were −1.50 ± 3.31 in the CST and 0.72 ± 3.50 in the control (p=0.036), effect size for CST group was d=0.65, which is considered medium effect. CST showed decrease in emotional exhaustion and negative affects, and increase in lymphocytes, erythrocyte parameters and platelets between the baseline and five-week (p<0.05). Reduction in IL-1β and increase in total lymphocyte count were observed with 2–3 sessions per week, but that does not maintain when the number of sessions is decreased. Participants receiving ≥7 sessions reduced emotional exhaustion, depersonalization and stress, and improved hematological parameters throughout the study (p<0.05).

Conclusions

CST may be effective in reducing stress (exhaustion phase) compared to control. Higher frequency of interventions promotes better psychic state, evidenced by large effect size for emotional exhaustion in burnout, and improves hematological parameters of professionals.
Does the use of chitosan covered gauze for postpartum hemorrhage reduce the need for surgical therapy including hysterectomy? A databased historical cohort study
Authors: Biele Carolin , Radtke Laura , Kaufner Lutz , Hinkson Larry , Braun Thorsten , Henrich Wolfgang , Dückelmann Anna M.
Published: May 2022

Objectives

Postpartum hemorrhage (PPH) is still one of the leading causes of maternal mortality worldwide. Recently effective PPH therapy with uterine packing with the chitosan-covered gauze was shown. This databased retrospective case–control study compares the therapy success of the chitosan tamponade with that of the balloon tamponade and medical therapy only.

Methods

All women who delivered at a university hospital between May 2016 and May 2019 with PPH were included. Based on the applied therapy, women were divided into three groups: medical therapy only, balloon tamponade and chitosan tamponade. The groups were compared in terms of therapy success, side-effects and reasons for PPH. Primary outcome was the need for surgical/radiological measures including hysterectomy, secondary outcomes were differences in hemoglobin levels, duration of inpatient stay, admission to intensive care unit, number of administered blood products and inflammation parameters.

Results

A total of 666 women were included in the study. 530 received medical therapy only, 51 the balloon tamponade and 85 the chitosan tamponade. There were no significant differences in the need for surgical therapy, but a significantly lower number of hysterectomies in the chitosan tamponade group than in the balloon tamponade group. There were no relevant differences in secondary outcomes and no adverse events related to the chitosan tamponade. Since the introduction of chitosan tamponade, the number of PPH related hysterectomies dropped significantly by 77.8%.

Conclusions

The chitosan tamponade is a promising treatment option for PPH. It reduces the postpartum hysterectomy rate without increased side effects compared to the balloon tamponade.

The subsequent activated carbons of resorcinol-formaldehyde xerogels are synthesized and exposed to wide range of gamma irradiation dose. Xerogels and their subsequent activated carbons are characterized by diverse techniques; FTIR, Raman, porosity analysis, SEM, EDX and AFM. The composite membranes are fabricated from polyacrylonitrile and activated carbon xerogels as composite membranes to be utilized in ultrafiltration process of salted oily wastewater. The soybean oil is exploited as organic feeding solution. The results declared that values of flux and rejection reach 157 (L m−2 h−1) and 99.8 (%), respectively. Overall, the best performing composite membrane is conducted by maximizing pure water flux. The optimally synthesized membrane performs well for purification of salted oily wastewater, and a significant increment in permeate flux is obtained with soybean oil rejection is at ∼99.8% and with maximum flux is at 32 (L m−2 h−1). Further, the composite membranes showed good promise for ultrafiltration of salted oily wastewater.

J Strength Cond Res 37(2): 403–412, 2023—Despite the popularity of 3 × 3 basketball rapidly growing on a global scale, a paucity of data exist on player demands during competition, particularly considering various factors. This study aimed to quantify the technical-tactical demands of international-level 3 × 3 basketball games according to game outcome, player sex, and competition phase. Overall, 96 players from 24 national teams (48 players across 12 teams in each sex) competing at the 2019 European Basketball Cup 3 × 3 were included in this study. Technical-tactical demands during games including shooting, game-related, and possession-related statistics were retrospectively gathered from public sources or analyzed using video analyses. Linear mixed models and effect size analyses were used to determine differences in demands according to game outcome (wins vs. losses), player sex (males vs. females), and competition phase (group games vs. finals games). Winning teams (p < 0.05, small-large) scored more shots, shot more efficiently, secured more rebounds, committed fewer turnovers and fouls, and drew more fouls to shoot free-throws. Differences between sexes (p < 0.05, small-moderate) showed male teams shot more efficiently, scored more 2-point shots, and scored more points, whereas female teams attempted more 1-point shots, committed more turnovers, and had more possessions. Considering the competition phase, more blocks were completed during group games, and more points per possession were achieved during finals games (p < 0.05, small). This study provides foundation normative values regarding the technical-tactical demands of 3 × 3 game-play during an international competition, with reported data able to be used by practitioners in developing precise, sex-specific training and tactical strategies to optimize team success.

Stress is often associated with negative consequences, and this also applies in the context of memory retrieval. However, Smith, Hughes, et al. (2019) proposed that this relationship only holds for information stored in episodic memory, because it relies on the hippocampus. In contrast, conceptual knowledge is stored in semantic memory, which is associated with neocortical and striatal brain regions that are upregulated during stress. Indeed, Smith, Hughes, et al. (2019) found that people experiencing acute psychosocial stress performed better on a subsequent trivia questionnaire compared to a control group. Moreover, performance correlated positively with cortisol reactivity. These findings are important, novel, and perhaps somewhat surprising, hence it is important to establish their generalizability. The latter is accomplished in the present study through a multiverse analysis. The results showed that the effect is relatively robust to variations in the scoring rules for the trivia questionnaire, the type of statistical model being used, and the inclusion versus exclusion of gender as a covariate in the analyses. However, we obtained mostly null effects when using the change in psychological stress levels as a predictor variable, and/or when only considering questions that were actually answered. The latter finding in particular is worrisome as it might point to alternative explanations. That is, stress might improve performance, because participants are more engaged with the task or are more prone to guess, regardless of its (potential) impact on semantic memory retrieval. Hence, it is premature to conclude that stress enhances semantic memory.
Conductus, Sequence, Refrain
Authors: Caldwell Mary Channen
Published: May 2022

Latin conducti do not typically come to mind when considering the medieval practice of French refrain citation; intertextual refrains were conventionally interpolated into French songs, narratives, and the upper voices of motets. Yet three conducti copied in late thirteenth-century northern French manuscripts intervene in this traditional narrative by engaging compositionally with French refrains: Veni sancte spiritus spes in GB-Lbl Egerton 274 (known as LoB or Trouvère F), and Marie preconio and Superne matris gaudia in F-Pn lat. 15131 (the St. Victor Miscellany). Previously identified as contrafacts of French refrain songs, Veni sancte spiritus spes shares its melody with a widely cited French refrain, while Marie preconio and Superne matris gaudia are rubricated with French refrains and scribal cues that suggest a musical relationship with French refrains. However, the poems of these conducti exhibit significant relationships not with French refrains but with homonymous and widely sung liturgical sequences. These conducti are not simply contrafacts but reflect a compositional negotiation between variously borrowed and new elements, resulting in Latin songs implicated within citational networks of liturgical chant and French refrains. Significantly, the repeated refrain serves in each song as the site for intertextual and intermusical processes, with borrowed material from French refrains and Latin sequences shaping the music and poetry of the new refrain-form conducti. Considered together, these conducti shed light on understudied Latin contexts for practices of multilingual intertextuality and intermusicality in late thirteenth-century France.

Obese women often have certain degree of reproductive dysfunction with infertility. Although the clinical impact of obesity on female infertility has been extensively studied, the effective and targeted treatment is still lacking. Melanocortin-4-receptor knock-out (MC4R KO) mouse is an over-eating obese model with hyperphagia, hyperinsulinemia, reduced growth hormone (GH), and insulin resistance. Dapagliflozin improved the metabolic and hormonal parameters in MC4R KO mice. MC4R KO female mice were treated with dapagliflozin for 14 weeks from 14-week age. Age-matched WT littermates and non-treated MC4R KO mice were used as control groups. Food intake was measured daily. Body weight was measured twice a week. Estrous cycles, GH, and luteinizing hormone (LH) profiles were measured. Selected tissues were collected at the end of experiments for gene expression profiles and hematoxylin–eosin staining. Regularity and mode of hormonal profiles were restored by the dapagliflozin treatment. Estrous cycle was partially normalized, number of CL was significantly increased, and the expression of Kiss1 and Gnrh1 in the hypothalamus and LH in the pituitary was markedly increased by the dapagliflozin treatment. It is conclsuded that dapagliflozin may recover LH and GH profiles partially through modification of relevant gene expression in the hypothalamus and pituitary, and result in an improved ovulation rate in obese mouse model. Dapagliflozin may therefore improve fertility in obese patients.

Left subclavian artery esophageal fistula usually occurs after esophageal cancer surgery, which is a rare complication, and it is even rarer after stent implantation of left subclavian artery pseudo-aneurysm. This paper reports the case of a 21-year-old male patient with left subclavian artery pseudo-aneurysm. Two-plus months after stent implantation, he stopped anticoagulant and antiplatelet drugs and developed pain in his left upper limb. The patient was diagnosed with arterial fistula. He was discharged from the hospital successfully after several operations, such as thoracic aortic stent implantation, left common carotid artery left axillary artery artificial vascular bypass.
Conclusion: Early diagnosis and positive treatment lead to a good prognosis for patients with esophageal left subclavian artery fistula.

Trastornos de las estructuras dentales o pulpares, en los primordios del desarrollo de la raíz, pueden deberse a factores de incidencia directa como caries o traumas, pero también a indirectos como la reabsorción intracoronal pre-eruptiva (PEIR). El tratamiento conservador de preservación de la viabilidad pulpar utilizando MTA (Agregado de Trióxido Mineral, en inglés Mineral Trioxide Aggregate) ha sido recomendado en diferentes estudios. El propósito de este reporte de caso es presentar al MTA como alternativa para terapia pulpar vital (TPV) en canino inferior (diente 33) con ápice abierto y control radiográfico a 4 años (2011 – 2015). Para ello, se abordó a paciente masculino de 13 años, en 2011, con caries favorecida por presunta reabsorción intracoronal pre-eruptiva, en canino inferior con ápice abierto, por cuanto en la anamnesis se informó que el canino, al ir erupcionando, se iba resquebrajando, sin motivo aparente, lo cual, en la literatura, se asocia con este diagnóstico. Se llevó a cabo un tratamiento conservador de pulpotomía usando MTA con seguimiento clínico-radiográfico a 4 años. Como resultado se logró conservar, sin procedimientos invasivos, la pulpa radicular y con ello se garantizó la formación completa de la raíz. Durante el seguimiento no se evidenció ningún tipo de hallazgo relacionado con alteraciones periapicales, lo que evidencia que el MTA es una alternativa para TPV en dientes con ápice abierto.

Published: May 2022

Both adaptive dynamic programming and other intelligent algorithms can solve the economic dispatch problem in the microgrid. Adaptive dynamic programming can reduce the computational burden, which the intelligent algorithms suffer from, by using function approximation structure to approximate performance index function. In recent years, it has been also widely used in economic dispatch in the microgrid. In this article, we introduce some recent research trends within the field of adaptive dynamic programming based economic dispatch. Adaptive dynamic programming is firstly reviewed. Then, the current research works about adaptive dynamic programming based economic dispatch are summarized and compared. Furthermore, we point out some topics for future studies.
