The Effects of Outdoor Air Supply Rate and Supply Air Filter Condition in Classrooms on the Performance of Schoolwork by Children (RP-1257)

Two independent field intervention experiments were carried out in mechanically ventilated classrooms receiving 100% outdoor air. Outdoor air supply rate and filter condition were manipulated to modify indoor air quality, and the performance of schoolwork was measured.The conditions were established for one week at a time in a blind crossover design with repeated measures on 10- to 12-year-old children in two classes. Seven exercises exemplifying different aspects of schoolwork (numerical or language-based) were performed as part of normal lessons by pupils who also marked visual analogue scales to indicate their environmental perceptions and the intensity of any symptoms. The children indicated that the air was fresher but otherwise perceived little difference when the outdoor air supply rate increased from 3.0 to 8.5 L/s (6.4–18 cfm) per person, while the speed at which they performed two numerical and two language-based tasks improved significantly. A significant effect of ventilation rate was observed in 70% of all the statistical tests for an effect on work rate, but there were no significant effects on errors. The effects were probably due to improved air quality in the classrooms as judged by a sensory panel of adults blind to conditions, as perceived by children, and as indicated by the reduction in the average CO2 concentration from 1300 to 900 ppm, taking this as a marker of reduced bioeffluent concentration. It was not possible to test the effect of replacing a soiled filter with a new one because very little dust had been retained by the “used” filter and because of an incompletely balanced design. The unbalanced design also made it impossible to test for an interaction between filter condition and ventilation rate. These results indicate the importance of improving indoor air quality and ventilation in classrooms.
CURT1A and CURT1C mediate distinct stages of plastid conversion in Arabidopsis

The crystalline structure of prolamellar bodies (PLBs) and light-induced etioplasts-to-chloroplasts transformation have been investigated with electron microscopy methods. However, these studies suffer from chemical fixation artifacts and limited volumes of tomographic reconstruction. We have examined Arabidopsis thaliana cotyledon samples preserved by high-pressure freezing with scanning transmission electron tomography to visualize larger volumes in etioplasts and their conversion into chloroplasts. PLB tubules were arranged in a zinc blende-type lattice like carbon atoms in diamonds. Within 2 hours after illumination, the lattice collapsed from the PLB exterior and the disorganized tubules merged to form fenestrated sheets that eventually matured into lamellar thylakoids. These planar thylakoids emerging from PLBs overlapped or folded into grana stacks in PLBs’ vicinity. Since the nascent lamellae had curved membrane at their tips, we examined the localization of CURT1 proteins. CURT1A transcript was most abundant in de-etiolating cotyledon samples, and CURT1A concentrated at the peripheral PLB. In curt1a mutant etioplasts, thylakoid sheets were swollen and failed to develop stacks. In curt1c mutant, however, PLBs had cracks in their lattices, indicating that CURT1C contributes to cubic crystal growth under darkness. Our data provide evidence that CURT1A and CURT1C play distinct roles in the etioplast and chloroplast biogenesis.
The effect of technological packages on maize productivity in Ecuador

This article analyzes the effect of adopting hybrid maize on productivity per hectare, using data obtained from 1,622 producers in Ecuador. Special attention is given to examining whether there are differences between producers who adopted maize independently and those who did so through a technological package –partially subsidized by the state– which, in addition to hybrid seed, included complementary technologies, training, and technical assistance. The findings show that adopting hybrid seed had a positive impact on productivity per hectare, regardless of whether it was adopted independently or as part of a technological package. However, producers who adopted the technological package clearly saw the greatest increase in productivity.
Characteristics of Peripheral Arterial Disease Patients in Vascular and Endovascular Surgery Department Dr. Mohammad Hoesin General Hospital between January 2018 - December 2019

Background: Peripheral artery disease (PAD) is a chronic occlusive arterial disease of the extremities caused by atherosclerosis leading to stenosis or occlusion characterized by decreased blood flow to the limb, due to obstruction or narrowing of the blood vessels. PAD often underdiagnosed and poorly understood. ​​Median annual expenditure per individual for patients with PAD was $ 11.553 to $ 42.613 in the United States. The lack of data on PAD in South Sumatra was the based for investigators to conducting this study. Methods: This research is a retrospective descriptive study. The purpose of this study was to describe the characteristics of PAD patient based on the Rutherford classification. There are 33 cases in this study. Result: The dominant patient was male, the youngest age was 28 years old and the oldest age was 71 years, with a mean age of 55.8 years. Diabetes mellitus, stage 1 hypertension, LDL more than 100 mg/dL, ABI results that showed PAD, and stage 2 Rutherford were the dominant cases in the sample of this study. Conclusion: Early prevention and treatment from vascular and endovascular surgery can be considered as the most important for the management of peripheral arterial disease patient.
On the equivalence of uniform and two-layer soils to multilayer soils in the analysis of grounding systems

An extensive study of the equivalence of uniform and two-layer soils to multilayer soils in the analysis of grounding systems has been carried out. Grounding resistances and touch voltages have been computed and compared for different equivalent soil models. The analysis presented shows how to obtain an approximate uniform or two-layer equivalent soil for some multilayer soils. It also shows that a good equivalent soil with respect to ground resistance is not necessarily good with respect to touch voltages. Examples showing the lower and upper bounds of electric responses associated with grounding systems in different equivalent soils are also presented.
Surveillance of Injury Types, Locations, and Intensities in Male and Female Tennis Players: A Content Analysis of Online Newspaper Reports

The popularity of modern tennis has contributed to the increasing number of participants at both recreational and competitive levels. The influx of numerous tennis participants has resulted in a wave of injury occurrences of different types and magnitudes across both male and female players. Since tennis injury harms both players’ economic and career development, a better understanding of its epidemiology could potentially curtail its prevalence and occurrences. We used online-based tennis-related injury reports to study the prevalence, location types, and injury intensities in both male and female tennis players for the past five years. It is demonstrated from the chi-square analysis that injury occurrences are significantly associated with a specific gender (χ2(18) = 50.773; p = 0.001), with male players having a higher risk of injury manifestation (68.10%) as compared with female players (31.90%). Nonetheless, knee, hip, ankle, and shoulder injuries are highly prevalent in both male and female players. Moreover, the injury intensities are distributed across gender (χ2(2) = 0.398; p = 0.820), with major injuries being dominant, followed by minor injuries, whilst a few cases of career-threatening injuries were also reported. It was similarly observed that male players recorded a higher degree of both major, minor, and career-threatening injuries than female players. In addition, male players sustained more elbow, hip, knee, shoulder, and thigh injuries than female players. Whereas, female players mostly suffered from Achilles and back injuries, ankle and hamstring injuries affected both genders. The usage of online newspaper reports is pivotal in characterizing the epidemiology of tennis-related injuries based on locations and gender to better understand the pattern and localization of injuries, which could be used to address the problem of modern tennis-related injuries.
Worldwide and Regional Efficacy Estimates of First-line Helicobacter pylori Treatments

Supplemental Digital Content is available in the text. Background: Eradication of Helicobacter pylori infection is challenging. We aimed to determine the optimal first-line H. pylori treatments at global and regional levels. Methods: We searched Embase, PubMed, Cochrane CENTRAL, Web of Science, Scopus, WHO ICTRP, ClinicalTrials.gov, and ISRCTN registry, for randomized controlled trials published during 2011-2020. Utilizing a network meta-analysis in a Bayesian framework, success rates of 23 regimens were compared. The effect size was standardized risk ratio (RR) with 95% credible interval (CrI). Pooled eradication rate (ER) with 95% CrI was also reported for top combinations. The reference regimen was 7-day clarithromycin-based triple therapy. Results: This review identified 121 trials comprising 34,759 participants. Globally, 14-day levofloxacin-based sequential therapy was the most efficient (RR: 1.43; 95% CrI, 1.26-1.59) with low certainty of evidence, followed by modified bismuth-containing quadruple therapy (proton pump inhibitor+bismuth compounds+clarithromycin+amoxicillin) for 10 days (RR: 1.35; 95% CrI, 1.22-1.48) and 14 days (RR: 1.27; 95% CrI, 1.12-1.42), and 14-day hybrid therapy (RR: 1.27; 95% CrI, 1.19-1.36). The corresponding ERs were 98.7% (95% CrI, 86.9-100.0), 93.2% (95% CrI, 84.2-100.0), 87.6% (95% CrI, 82.1-93.8), and 87.6% (95% CrI, 77.3-98.0), respectively. Continentally, the most effective combinations were: 10-day clarithromycin-based sequential therapy [(RR: 1.21; 95% CrI, 1.02-1.42), (ER: 89.5%, 95% CrI, 75.5-100.0)] for Africa, 14-day levofloxacin-based sequential therapy [(RR: 1.41; 95%CrI, 1.27-1.58), (ER: 98.7%, 95% CrI, 88.9-100.0)] for Asia, and 14-day clarithromycin-based triple therapy [(RR: 1.58; 95% CrI, 1.25-2.04), (ER: 94.8%; 95% CrI, 75.0-100.0)] for Europe. For Northern America, no sufficient data were found for network meta-analysis. In South America, none of the combinations were superior to the reference regimen. Conclusion: Although results of this network meta-analysis revealed optimal combinations for empiric therapy, the treatment preference would be based on the local pattern of antibacterial resistance, when the necessary information exists.
Antidiabetic effects of quercetin and liraglutide combination through modulation of TXNIP/IRS‐1/PI3K pathway

The study was designed to assess the possible augmented antidiabetic effects of combining quercetin and liraglutide in a type 1 diabetes model, with emphasis on the contribution of hepatic thioredoxin interacting protein (TXNIP)/insulin receptor substrate 1 (IRS‐1)/phosphatidyl inositol‐3 kinase (PI3K) pathway. The wound‐healing effects were also examined. Diabetes was induced by a single i.p STZ injection (55 mg/kg). Diabetic rats were treated with either quercetin (100 mg/kg/day, orally) or liraglutide (0.3 mg/kg/twice daily, S.C.) or their combination. Drugs were also applied topically on the wound. Blood glucose levels, serum albumin, total protein, total cholesterol and triglycerides were measured. Histopathological examination of the liver, pancreas and skin tissues was performed using haematoxylin and eosin staining. The hepatic malondialdehyde level was measured spectrophotometrically. Hepatic TXNIP and PI3K levels were measured by enzyme‐linked immunsorbent assay (ELISA). Tissue expression of IRS‐1 and phospho‐IRS‐1 (Ser 616) was assessed by immunohistochemistry. Quercetin, liraglutide and their combination effectively decreased blood glucose levels, improved lipid profile, upregulated albumin and total protein serum levels and reduced hepatic oxidative stress with the combination being most effective. Moreover, the combination group showed enhanced wound‐healing effects and almost normalized hepatic and pancreatic histopathology. Quercetin and/or liraglutide significantly decreased TXNIP levels and serine phosphorylation of IRS‐1 and increased PI3K levels compared to the diabetic untreated group. Interestingly, only the combination therapy normalized hepatic IRS‐1 expression. The combination of quercetin and liraglutide showed enhanced antidiabetic effects, possibly through lowering hepatic TXNIP levels, with the resultant up‐regulation of the IRS‐1/PI3K pathway.
COVID-19 Prevention Measures Implemented by Tennis Coaches: The Role of Continent, Experience, and Type of Facility

The prevention strategies used by tennis coaches when delivering tennis lessons during the COVID-19 pandemic were analyzed in this study. An ad hoc questionnaire collected data from 655 Spanish and Portuguese speaking tennis coaches working in Latin America and Europe. Differences in the prevention measures were analyzed according to the continent, the coaches’ experience, and the type of facility they worked in. Results showed that coaches used information provided from local and national organizations more than from international ones. Hand hygiene, communication of preventive strategies, and changes in the coaching methodology were the most used prevention measures. Latin American coaches and those working in public facilities implemented the measures more often than their European colleagues or those working in private venues. Finally, more experienced coaches showed a greater awareness of the adoption of the measures than their less experienced counterparts. The data provided by this research may assist in developing new specific guidelines, protocols, and interventions to help better understand the daily delivery of tennis coaching in this challenging context.
Navigating the Notches: Charity Responses to Ratings

This paper studies both donor and nonprofit responses to the star rating system designed by Charity Navigator. Using IRS Form 990 data from 2002 to 2019, I find that an increase in a charity’s rating from 3to the highest 4-star rating is associated with a 6% rise in contributions, with larger effects among smaller charities. Some charities respond to the incentives by changing their behavior to try to get themselves above the star thresholds, leading to “bunching” at the thresholds. This response is equal to the effect of charities halving spending on administration. I find that some of the response is due to misreporting of expenses in order to achieve a higher star rating. The analysis suggests that a notched rating system induces greater behavioral change than a continuous measure, but affects a smaller number of charities. Which rating system is preferred depends on the relative value placed on these effects. ∗Email: jenmayo@umich.edu.

Tools and Teaching Strategies for Vocabulary Assessment and Instruction: A Review

Vocabulary is a complex intermediate component between oral and written language, which the influence on associated skills and general language abilities (e.g., decoding processing, comprehension) has been largely studied in children, suggesting its important role in literacy. The main aim of this article is to review some questions on vocabulary assessment and stimulation in children and identify the advantage of new technologies for evaluating and training vocabulary. It seems necessary to give the importance of vocabulary in language and literacy development, and the heterogeneity of vocabulary acquisition, depending on preschool word exposure (e.g., familial environment). After a state-of-the-art of conceptualization of vocabulary’s notion, we revisit assumptions on vocabulary assessment and instruction indicating the main existing tools. This review lies in the attempt to enhance perspectives for new valid and effective tools using digital technologies.
End to End Video Compression Based on Deep-Learning

— Recent years have shown exponential growth in video processing and transfer through the Internet and other applications. With the restriction on bandwidth, processing and storage there is an extensive demand for end-to-end video compression. Many conventional methods have been developed to compress video. However, with the extensive use of Artificial Intelligence, AI, such as Deep Learning (DL) have emerged as a best-of-breed alternative for performing different tasks have been also been used in the option of improving video compression in last years, with the primary objective of reducing compression ratio while preserving the same video quality. Evolving video compression research based on Neural Networks (NNs) focuses on two distinct directions: First; enhancing current video codecs by better predictions integrated even in the same codec framework, and second; holistic end-to-end VC systems approaches. Although some of the outcomes are optimistic and the results are well, no breakthrough has been reported previously. This paper review of new research work, including samples of few influential articles that demonstrate and further describe the various highlighted issues in the aria of using DL for end to end video compression.
Effects of rations containing leubiem fish (Chanthidermis maculatus) waste and phytogenic suplementation on local ducks performance in the starter phase

This study aims to examine the potential use of leubiem fish (Chanthidermis maculatus) waste and phytogenic supplementation on ration, in order to increase the performance of local ducks in the starter phase. This study used 100 local ducks aged 1 week old, and maintained them until 8 weeks old. The ducks were placed in 5 treatments and 4 replications groups (5 ducks / repetition). The study was conducted experimentally, using a Completely Randomized Design (CRD), consisting of 5 ration treatments, including: R1 (control); R2 (basal ration containing leubiem fish skin flour 10% + phytogenic 0.5%); R3 (basal ration containing leubiem fish head flour 10% + phytogenic 0.5%); R4 (basal ration containing leubiem fish bone flour 10% + phytogenic 0.5%) and R5 (basal ration containing leubiem fish gill flour + phytogenic 0.5%). Observed variables were feed consumption, body weight gain, final weight, feed conversion, and local duck mortality in the starter phase. The data obtained were both analyzed using Analysis of Variance (ANOVA) and Duncan’s multiple range test. The results showed that the use of leubiem fish waste and phytogenic supplementation in the ration both increased the performance of local ducks in the starter phase and had a significant effect (p <0.05) on ration consumption, weight gain, and final weight. However, they had no significant effect on feed conversion and local duck mortality in the starter phase. It was concluded that the use of leubiem fish (10% bone meal) and phytogenic supplementation 0.5% in the ration was able to increase body weight gain, and the final weight of the starter phase local ducks (aged 1-8 weeks).
Corrigendum: Fractal squares with finitely many connected components (2021 Nonlinearity 34 1817–1836)

The original proof of proposition 5.4 in the ‘further remarks’ section of [2] is incorrect. The mistake lies in the last paragraph: it has only been shown that φn(C∗) is contained in a 2N−nneighbourhood of C, but the converse does not hold in general. So we cannot have the conclusion that h(C,φn(C∗)) 2N−n as in the original proof. The following presents a correct proof of this proposition. It is also noteworthy that there is an additional mild requirement (i.e., |D| > 1) in our new version of this proposition to avoid trivial exceptional cases. This modification does not make a difference to later proofs and results (and hence to any other results in [2]).
2D electrical resistivity imaging to determine depth of andesite spreading at Tanjung Batu, Jambi as eco-friendly exploration of minerals method

Tanjung Batu has potential subsurface minerals in the form of Andesite rocks. Andesite can be used appropriately for infrastructure with excellent physical features, including hardness, compressive strength, density, as well as the water and weather resistance level. Andesite is one type of igneous rock that is widely used in the construction sector, especially infrastructure such as roads, bridges, housing, airports, and seaports. In mining, the depth of mineral exploration usually using borehole method. In this study used electrical resistivity method with dipole-dipole configurations. Electrical resistivity is also capable for identifying Andesite rocks in subsurface without drilling the area because each rock has a different rock resistivity value. In this study used 240 meters of track and 20 meters space of electrodes. Based on 2D Imaging, range of Andesite resistivity in this area was 170 - >1095 Ωm. Andesite depth was at 3.42, 10.6, 18.5 and - 27.2 m.
Particle size distribution and clay minerals in dryland soils of Aceh Besar, Indonesia

Soil particle size distribution is a fundamental physical property affecting other soil properties. This research aims to determine the distribution of soil particles and the composition of clay minerals on each layer of the horizon in four soil profiles (P1, P2, P3, and P4) with different parent materials in the dryland of Aceh Besar district which includes Entisols Jantho, Andisols Saree, Inceptisols Cucum, and Oxisols Lembah Seulawah. Particle size distribution (or texture) and bulk density (BD) were analyzed in the laboratory. Soil structure and consistency were observed directly in the field. The type of clay minerals was identified by X-ray diffraction, while Fe, Al, and Si-oxide were extracted by dithionite-citrate solution. The results shown that the particle size distribution and the physical properties of dryland soils of Aceh Besar vary between soil orders. Andisols Saree has better physical properties than the physical properties of other soils and low bulk density. The Al, Fe, and Si fractions and clay mineral composition in the soil profiles also vary considerably between soil orders. The Andisols are dominated by allophane minerals (amorphous fractions) while Entisols, Inceptisols and Oxisols consist of mixed minerals of feldspar, quartz, halloysite, goethite, and other clay minerals. These soil orders have some soil physical constraints i.e. high soil bulk density, low water holding capacity and poor soil structures. Improvements in the physical properties of the soil on Aceh Besar dryland are indispensable to improve the quality of the soil.
