In the preceding times, the number of enclosed parking garages has increased significantly in developing nations. The toxic emissions from vehicular exhausts are expected to drastically compromise the environmental conditions of the parking garages. Subsequently, exposure of humans to these accumulated pollutants is also expected to degrade their health. Therefore, in the present investigation, efforts were made to estimate the applicability of TiO2-mediated UV photocatalysis in degrading the concentration of vehicular emissions, viz., NOx and SO2, in the enclosed parking garages (EPGs). In this regard, an artificial EPGs’ environment was created and experiments were designed using the Box-Behnken design in combination with response surface methodology. The process parameters chosen for maximizing the degradation of the pollutants were a concentration of TiO2 emulsion (20 to 120 ml/m2), UV irradiance (1 to 5 mW/cm2), and relative humidity (10 to 50%). Optimization of the laboratory experiments revealed that at optimal conditions of the process parameters, i.e., a concentration of TiO2

, maximum degradation of the NOx and SO2, i.e., 61.24% and 55.05%, respectively, was achieved. Further, it was revealed that relative humidity may prove to be the limiting factor while using the TiO2-mediated UV photocatalysis in humid areas. Findings of this study may prove beneficial in urban planning as it may assist scientific auditory and local authorities in identifying the applicability of TiO2-based photocatalysis in mitigating the impacts of vehicular emissions.
Rainer Maria Rilke e Paula Modersohn-Becker Um diálogo inspirador no Réquiem a uma Amiga
Authors: Rosenfield Kathrin , Pereira Lawrence Flores 
Published: July 2021

Este artigo apresenta o Réquiem a uma Amiga (tradução no final do artigo) com algumas reflexões ensaísticas sobre o lugar desse poema na obra do poeta R. M. Rilke. Iniciaremos com observações biográficas (os encontros do poeta com a escultora Clara Westhoff e sua amiga Paula em Paris em 1900) que ocasionaram o estudo da pintura de paisagem e um pequeno livro de ocasião de Rilke sobre a colônia de artistas de Worpswede, no norte da Alemanha. O forte impacto que esses encontros – e em particular a análise das telas de Paula Modersohn-Becker em 1905 - tiveram sobre a sensibilidade poética de Rilke contribuíram para a nova forma estilística (Dingwendung) que se manifesta na obra madura de Rilke. Apresentamos assim um momento de vida e um aspecto específico do desenvolvimento da relação do poeta e de sua obra com as artes plásticas, que ilumina o papel da poesia como trabalho de luto do poeta e como prefiguração das obras da fase madura dos Sonetos e das Elegias.

Published: July 2021

Background
Arterial hypertension affects cardiovascular outcome in patients with peripheral artery disease (PAD). We hypothesized that angioplasty of peripheral arterial stenoses decreases aortic (aBP) and brachial blood pressure (bBP).

Methods and Results

In an index cohort (n=30), we simultaneously measured aBP, bBP, augmentation index (AIx), and aortic pulse wave velocity (PWV) before and after angioplasty of the iliac and femoropopliteal arteries; diagnostic angiography served as a control. In an all‐comer registry cohort (n=381), we prospectively measured bBP in patients scheduled for angioplasty of the iliac, femoral, and crural arteries or diagnostic angiography. Systolic aBP decreased after iliac (Δ−25 mmHg; 95% CI, −30 to −20;
P
<0.0001) and femoropopliteal angioplasty (Δ−12 mmHg; 95% CI, −17 to −5;
P
<0.0001) as compared with diagnostic angiography. Diastolic aBP decreased after iliac (Δ−9 mmHg; 95% CI, −13 to −1;
P
=0.01) but not femoropopliteal angioplasty. In parallel, AIx significantly dropped, whereas PWV remained stable. In the registry cohort, systolic bBP decreased after angioplasty of the iliac (Δ−17 mmHg; 95% CI, −31 to −8;
P
=0.0005) and femoropopliteal arteries (Δ−10 mmHg; 95% CI, −23 to −1;
P
=0.04) but not the crural arteries, as compared with diagnostic angiography. Diastolic bBP decreased after iliac (Δ−10 mmHg; 95% CI, −17 to −2;
P
=0.01) and femoropopliteal angioplasty (Δ−9 mmHg; 95% CI, −15 to −1;
P
=0.04). Multivariate analysis identified baseline systolic bBP and site of lesion as determinants of systolic bBP drop after endovascular treatment.

Conclusions
Angioplasty of flow‐limiting stenoses in patients with peripheral artery disease lowers aortic and brachial blood pressure with more pronounced effects at more proximal lesion sites and elevated baseline systolic blood pressure. These data indicate a role of endovascular treatment to acutely optimize blood pressure in patients with peripheral artery disease.

Sex-dependent divergence in asymmetrical reproductive tract morphology between two closely-related amphisbaenian species (Squamata: Amphisbaenidae)
Authors: Angiolani-Larrea Francesca , de Fraga Rafael , Mortati Amanda , Ribeiro Síria 
Published: July 2021

Abstract
Comparing reproductive tract morphology between closely-related species may reveal mechanisms and processes leading to reproductive isolation and cladogenesis. Differences in external morphology are often inconspicuous between closely-related Neotropical species, and tissue samples for DNA sequencing are usually scarce for fossorial organisms such as amphisbaenians. Therefore, comparing characters of the reproductive tract between closely related amphisbaenians may be a viable alternative to understand processes by which evolutionary lineages have diverged morphologically from common ancestors. In this study we used multivariate ordination to compare reproductive tract morphology between two closely-related Amphisbaenidae species (Amphisbaena anaemariae and A. silvestrii), which are morphologically similar, and phylogenetically closely related. We tested the hypothesis that interspecific divergence in the reproductive tract may explain mechanisms and processes of reproductive divergence leading to evolutionary divergence. Our results suggest that divergence between two closely related Amphisbaenidae species may be linked with reproductive isolation caused by morphological differences in the reproductive tract. However, the levels of divergence detected varied between sexes and sides of the body on which the variables were measured, with vas deferens length, testis length and diameter and gonad-cloaca length as the determining variables differencing species. Although our findings must be validated by DNA-based analysis, this study provides insights into evolutionary processes based on reproductive divergence mechanisms in organisms for which sampling is hindered by fossoriality.

Published: July 2021

AbstractIn this study, high-resolution surface and radar observations are used to analyze 24 localized extreme hourly rainfall (EXHR; >60 mm h−1) events with strong urban heat island (UHI) effects over the Great Bay Area (GBA) in South China during the 2011–16 warm seasons. Quasi-idealized, convection-permitting ensemble simulations driven by diurnally varying lateral boundary conditions, which are extracted from the composite global analysis of 3–5 June 2013, are then conducted with a multilayer urban canopy model to unravel the influences of the UHI and various surface properties nearby on the EXHR generation in a complex geographical environment with sea–land contrast, topography, and vegetation variation. Results show that EXHR is mostly distributed over the urban agglomeration and within about 40 km on its downwind side, and produced during the afternoon-to-evening hours by short-lived meso-γ- to meso-β-scale storms. On the EXHR days, the GBA is featured by a weak gradient environment with abundant moisture, and a weak southwesterly flow prevailing in the boundary layer (BL). The UHI effects lead to the development of a deep mixed layer with “warm bubbles” over the urban agglomeration, in which the lower-BL convergence and BL-top divergence is developed, assisting in convective initiation. Such urban BL processes and associated convective development with moisture supply by the synoptic low-level southwesterly flow are enhanced by orographically increased horizontal winds and sea breezes under the influence of the herringbone coastline, thereby increasing the inhomogeneity and intensity of rainfall production over the “Π-shaped” urban clusters. Vegetation variations are not found to be an important factor in determining the EXHR production over the region.

Authors: Roemer Enid Chung , Kent Karen B. , Goetzel Ron Z. , Calitz Chris , Mills Drew 
Published: July 2021

Objective: To test the validity and reliability of the American Heart Association’s (AHA) updated Workplace Health Achievement Index (WHAI). Methods: We piloted the updated WHAI with respondent pairs at 94 organizations, and examined the inter-rater reliability (percent agreement) for each item on the survey. To evaluate face and content validity, we conducted preliminary focus groups pre-survey, and follow-up cognitive interviews post-survey administration. Results: Respondents found the updated WHAI to be comprehensive and useful in identifying gaps and opportunities for improving their health and wellbeing programs. The mean percent agreement on all items was 73.1%. Only 9% (or 14 items out of 146) had poor inter-rater reliability (below 61 percent agreement), but through follow-up cognitive interviews we determined that most were due to artifacts of the study design or were resolved through minor revisions to the survey question, instructions, and/or adding examples for clarity. Only 1 question was deleted due to lack of relevance. Conclusion: The updated WHAI is a valid and reliable tool for employers to assess how well they promote the health and wellbeing of their employees.
A novel full-electric aircraft propulsion based on the DEA compressor
Authors: Aryana Babak 
Published: July 2021

This article introduces a novel full-electric aircraft propulsion designed based on the DEA compressor, named DEAThruster that is supplied by a PEMFC. The thruster designed and modeled in this study is a compact DEAThruster to operate in altitudes up to 15,000 m and in the subsonic/transonic region with a specific thrust around 8300 N s/kg. The results show the thruster can satisfy all expectations, and it can generate up to 8300 N s/kg specific thrust for flight conditions encompassing static condition at sea level up to flight Mach number 0.95 in altitude 15,000 m. The DEAThruster can potentially be a practical alternative for gas turbine propulsions in all aspects when all available options for full-electric propulsions are not competitive for conventional aircraft propulsions in performance, size, and weight.
A comparison of monolingual and bilingual toddlers’ word recognition in noise
Authors: Morini Giovanna , Newman Rochelle S. 
Published: July 2021

Aims and objectives: The purpose of this study was to examine whether differences in language exposure (i.e., being raised in a bilingual versus a monolingual environment) influence young children’s ability to comprehend words when speech is heard in the presence of background noise. Methodology: Forty-four children (22 monolinguals and 22 bilinguals) between the ages of 29 and 31 months completed a preferential looking task where they saw picture-pairs of familiar objects (e.g., balloon and apple) on a screen and simultaneously heard sentences instructing them to locate one of the objects (e.g., look at the apple!). Speech was heard in quiet and in the presence of competing white noise. Data and analyses: Children’s eye-movements were coded off-line to identify the proportion of time they fixated on the correct object on the screen and performance across groups was compared using a 2 × 3 mixed analysis of variance. Findings: Bilingual toddlers performed worse than monolinguals during the task. This group difference in performance was particularly clear when the listening condition contained background noise. Originality: There are clear differences in how infants and adults process speech in noise. To date, developmental work on this topic has mainly been carried out with monolingual infants. This study is one of the first to examine how background noise might influence word identification in young bilingual children who are just starting to acquire their languages. Significance: High noise levels are often reported in daycares and classrooms where bilingual children are present. Therefore, this work has important implications for learning and education practices with young bilinguals.
Near Future Teaching: Practice, policy and digital education futures
Authors: Bayne Sian , Gallagher Michael 
Published: July 2021

When considering digital futures for universities it is the instrumentalising narratives developed by corporate ‘ed-tech’ which often drive the debate. These are narratives which, aligning tightly to marketisation, unbundling and other dominant ideological trends, describe a highly technologised, datafied and surveillant future for teaching. This future is often framed as an imperative, leaving university communities with the sense that a future is being designed for them over which they have relatively little control. This paper describes the theory, methods and outcomes of a project which set out to counter this tendency, using participative, co-design methods within a ‘top down’ policy initiative to envision an alternative future for digital education within our own institution. Our starting point was that universities need to get better at crafting their own, compelling counter-narratives concerning the future of technology in teaching, in order to assert the agency and presence of the academic and student bodies in the face of technological change. In working toward this, we drew on recent thinking in anticipation studies in education and developed an original methodology for participative futures work within universities. The paper reports on the outcomes of this project, and its implications for the sector more generally, arguing that university communities can work to define their own digital futures through an emphasis on collectivity, participation and hope.

Published: July 2021

Background and aims: The application of QuantiFERON-TB Gold in-Tube (QFT-GIT) in patients with haematological malignancies (HMs) has not been well studied. Therefore, we aimed to investigate the features of patients with HMs whose QFT-GIT results were indeterminate. Methods: This study enrolled patients with HMs for the analysis of QFT-GIT tests and additional 2-year follow-up. The characteristics and predictors of QFT-GIT indeterminate results were identified. Mycobacterium tuberculosis (TB) incidence rate (IR) and incidence rate ratio (IRR) were also investigated. Results: Of 89 participants, 27 (30.3%) had QFT-GIT indeterminate results. The QFT-GIT indeterminate patients were characterized with the diagnosis of leukaemia (63.0% versus 32.3%, p = 0.044), abnormal white blood count (WBC) (88.9% versus 14.5%, p = 0.001), abnormal lymphocyte percentage (81.5% versus 14.5%, p = 0.001) and lower lymphocyte count (×109/l) (0.5 versus 2.2, p = 0.000) when compared with those with determinate results. Meanwhile, abnormal WBC [odds ratios (OR): 15.18, p = 0.003] and lymphocyte percentage (OR: 6.90, p = 0.033) were predictors of indeterminate results. One patient with the QFT-GIT indeterminate status and high interferon-γ level of negative control result developed active TB with a TB IR of 18.5 per 1000 person-years and an IRR of 0.1 (95% confidence interval, 0.01–0.71) when compared with positive QFT-GIT patients without prophylaxis treatment. Conclusion: Abnormal ranges of WBC and lymphocyte differential count percentage were independent predictors useful to determine the optimal timing of implementing QFT-GIT test in patients with HMs.
Diversity of experience and labor productivity in creative industries
Authors: Kekezi Orsa 
Published: July 2021

AbstractThis paper studies how the previous experience among workers relates to the labor productivity of the creative industries in Sweden. Effective knowledge transfers are dependent on the cognitive distance among employees. Using longitudinal matched employer-employee data, I measure the portfolio of the skills within a workplace through (i) the workers' previous occupation, and (ii) the industry they have been working in previously. Estimates show that diversity of occupational experience is positive for labor productivity, but the diversity of industry experience is not. When distinguishing between related and unrelated diversity, the relatedness of occupational experience is positive for labor productivity, while unrelated occupational experience instead shows negative relationship with productivity. These results point towards the importance of occupational skills that workers bring with them to a new employment, for labor productivity.
Palmo-plantar hyperkeratosis associated with HTLV-1 infection: a case report
Authors: Quintero-Muñoz Elías , Arsanios Daniel Martin , Beltrán María Fernanda Estupiñán , Vera Juan David , Giraldo Catalina Palacio , Velandia Omar , Calderon Carlos Mauricio 
Published: July 2021

Abstract
Background
Palmoplantar hyperkeratosis is a cutaneous manifestation that had not been clearly associated with infection by the human T-cell lymphotropic virus, which is a retrovirus that in most cases does not develop clinical pathologies and its symptoms may be undetected. The skin is one of the most affected organs, however until now only seborrheic dermatitis, xerosis/ichthyosis and infective dermatitis associated with HTLV-1 have been described as cutaneous clinical manifestations of this disease.

Case presentation
We present the case of a 36-year-old male patient with serologically documented HTLV-1 infection, who presented symptoms of diarrhea, malabsorption due to Strongyloides stercoralis, and in whom a physical examination revealed an association with generalized xerosis and palmoplantar keratoderma confirmed by skin biopsy. Other infectious etiologies and malignancy were ruled out. This clinical manifestation was managed with dermal hydration, and skin care which improved the thickened skin and make it less noticeable.

Conclusions
According to our experience, this is the first reported case of palmoplantar keratoderma associated with a human lymphotropic virus infection. This is a skin manifestation that has not been confirmed in conjunction with HTLV-I before. This implies that palmoplantar keratoderma is a new clinical manifestation of this infection, that should be considered in the initial approach of patients in endemic areas with these dermatological characteristics.
Prediction of non-reassuring fetal status and umbilical artery acidosis by the maternal characteristic and ultrasound prior to induction of labor
Authors: Lu Jing , Jiang Jinna , Zhou Ying , Chen Qionghua 
Published: July 2021

AbstractObjectiveTo investigate the predictive value of pre-induction digital examination, sonographic measurements and parity for the prediction of non-reassuring fetal status and cord arterial pH < 7.2 prior to the induction of labor (IOL).MethodThis was a prospective observational study, including 384 term pregnancies undergoing IOL. Before the IOL, the Bishop score (BS) by digital examination, sonographic Doppler parameters and the estimated fetal weight (EFW) was assessed. The fetal cord arterial was sampled to measure the pH at delivery. Multivariate logistic regression analysis was performed to identify independent predictors of non-reassuring fetal status and low cord arterial pH.ResultsForty four cases (11.5%) had non-reassuring fetal status, and 76 cases (19.8%) had fetal cord arterial pH < 7.2. In the non-reassuring fetal status group, the incidence of cord arterial pH < 7.2 was significantly higher than that in the normal fetal heart rate group (χ2 = 6.401,p = 0.011). Multivariate analysis indicated that significant independent predictors of non-reassuring fetal status were nulliparity (adjusted odds ratio [AOR]: 3.746,p = 0.003), EFW < 10thpercentile (AOR: 3.764,p = 0.003) and cerebroplacental ratio (CPR) < 10thcentile (AOR:4.755,p < 0.001). In the prediction of non-reassuring fetal status, the performance of the combination of nulliparity and EFW < 10th percentile was improved by the addition of CPR < 10th percentile (AUC: 0.681, (95%CI: 0.636 to 0.742) vs 0.756, (95%CI:0.713 to 0.795)), but the difference was not significant (DeLong test: z = 1.039,p = 0.053).. None of the above variables were predictors of cord arterial pH < 7.2.ConclusionThe risk of fetal acidosis has increased in cases of non-reassuring fetal status. Nulliparity, small for gestational age and CPR < 10th centile are independent predictors for non-reassuring fetal status in term fetuses, though the addition of CPR < 10th centile could not significantly improve the screening accuracy.
