Published: October 2020

Abstract
COVID-19 pandemic outbreak, caused by the SARS-CoV-2 virus, affected millions of people worldwide causing hundreds of thousands of related fatalities. It is crucial to understand why the virus transmission seems to spread more easily in some regions with respect to others. The residuals, with respect to the modeled COVID-19 per-day hospitalized patients in Intensive Care Unit, were linked to meteorological and air-pollutant variables in four major metropolitan areas in Italy. COVID-19 pandemic related infections are slow down by higher tropospheric Ozone concentrations (p < 0.01). We quantitatively assessed that higher levels of tropospheric Ozone, already proven effective against viruses and microbial contaminants, play a role in flagging COVID-19 pandemic transmission. Because the tropospheric ozone production is depending, among others, by air-quality and sunlight, this can explain why the virus is spreading differential.

Abstract
Background: Many countries have recommended the use of face masks for general population in public places to reduce the risk of COVID-19 transmission. This study aims to estimate the prevalence of face mask usage and investigate about different types of face mask and their distribution among pedestrians in southwest Iran during the Covid-19 pandemic.Methods: This cross-sectional study was conducted in August 2020 in Ahvaz, southwest Iran. Using a multistage sampling method, a total of 10440 pedestrians selected from 8 urban districts and 92 neighborhoods of the city. The data gathered by observation method. Percentage, mean and standard deviation were used to describe the variables. Chi-square test, fisher exact test and Chi-square for trend used to assess relationship between two categorical variables. We used unconditional logistic regression model to control confounders.Results: The mean ± SD age of the observed pedestrians was 32.2 ±15.1 years and 67.9% of them were male. The overall prevalence of face mask usage was 45.6% (95% CI, 44.6 – 46.5). In general, as the age increased, the prevalence of face mask use significantly increased (p for trend <0.001). Women used face masks significantly higher than men (60.2% vs. 38.7%, p <0.001). Among the pedestrians who used the mask, 75.6 % wore facemask correctly. The most common type of facemask used by the pedestrians were surgical(medical) masks (63.8%). In total, the prevalence of facemask usage was significantly higher during a.m. (49.4%) compared to p.m. (43.9%), (p<0.001). Besides, in our study, 1.7% and 0.3 % of Pedestrians had worn gloves and shielded respectively. Women used shields and gloves significantly higher than men (3.6 % vs. 0.7%, p <0.001). Also, women used shields more than men (0.5 % vs. 0.3%, p =0.036).Conclusion: We concluded that the prevalence rate of face mask use in Ahvaz was fairly low especially in men and younger people. Hence, the observed rates probably cannot protect the community against COVID-19 spread. Therefore, it is important to implement educational programs as well as to establish laws and regulations governing the use of face masks in public places.

Abstract
Magnetite is the dominant Fe-oxide at the Acropolis IOCG prospect, Olympic Dam district, South Australia. Complementary microbeam techniques, including scanning transmission electron microscopy (STEM), are used to characterize titanomagnetite from veins in volcanic rocks and Ti-poor magnetite from a granite body with uplifted position in the volcanic sequence. A temperature of 670 ± 50 °C is estimated for Ti-poor magnetite using XMg-in-magnetite thermometry. Titanomagnetite, typified by Ti-rich trellis lamellae of ilmenite in magnetite, also displays sub-micrometer inclusions forming densely mottled and orbicular subtypes of titanomagnetite with increasing degree of overprinting. STEM analysis shows nanoparticles (NPs) of spinels and TiO2 polymorphs, anatase, and rutile. These vary as dense, finest-scale, monophase-NPs of spinel sensu stricto in Ti-poor magnetite; two-phase, ulvöspinelhercynite NPs in primary titanomagnetite; and coarser clusters of NPs (hercynite±gahnite+TiO2-polymorphs), in mottled and orbicular subtypes. Nano-thermobarometry using ilmenite-magnetite pairs gives temperatures in the range ~510–570 (±50) °C, with mineral-pair re-equilibration from primary to orbicular titanomagnetite constrained by changes in fO2 from ilmenite-stable to magnetite+hematite-stable conditions. Epitaxial relationships between spinel and Fe-Ti-oxides along trellis lamellae and among phases forming the NPs support exsolution from magnetitess, followed by replacement via mineral-buffered reactions. Lattice-scale intergrowths between ulvöspinel and ilmenite within NPs are interpreted as exsolution recording cooling under O2-conserving conditions, whereas the presence of both TiO2-polymorphs displaying variable order-disorder phenomena is evidence for subtly fO2-buffered reactions from anatase (reducing) to rutile (more oxidizing) stabilities. Transient formation of O-deficient phases is retained during replacement of ilmenite by anatase displaying crystallographic-shear planes. Development of dense inclusion mottling and orbicular textures are associated with NP coarsening and clustering during vein re-opening. Fluid-assisted replacement locally recycles trace elements, forming gahnite NPs or discrete Sc-Ti-phases. Hydrothermal titanomagnetite from Acropolis is comparable with magmatic magnetite in granites across the district and typifies early, alkali-calcic alteration. Open-fracture circulation, inhibiting additional supply of Si, Ca, K, and so on during magnetite precipitation, prohibits formation of silician magnetite hosting calc-silicate NPs, as known from IOCG systems characterized by rock-buffered alteration of host lithologies. Obliteration of trellis textures during subsequent overprinting could explain the scarcity of this type of hydrothermal magnetite in other IOCG systems.

Published: October 2020

AbstractAcoustic compressional and shear wave velocities (VP, VS) of anhydrous (AHRG) and hydrous rhyolitic glasses (HRG) containing 3.28 wt% (HRG-3) and 5.90 wt% (HRG-6) total water concentration (H2Ot) have been measured using Brillouin light scattering (BLS) spectroscopy up to 3 GPa in a diamond-anvil cell at ambient temperature. In addition, Fourier-transform infrared (FTIR) spectroscopy was used to measure the speciation of H2O in the glasses up to 3 GPa. At ambient pressure, HRG-3 contains 1.58 (6) wt% hydroxyl groups (OH–) and 1.70 (7) wt% molecular water (H2Om) while HRG-6 contains 1.67 (10) wt% OH– and 4.23 (17) wt% H2Om where the numbers in parentheses are ±1σ. With increasing pressure, very little H2Om, if any, converts to OH– within uncertainties in hydrous rhyolitic glasses such that HRG-6 contains much more H2Om than HRG-3 at all experimental pressures. We observe a nonlinear relationship between high-pressure sound velocities and H2Ot, which is attributed to the distinct effects of each water species on acoustic velocities and elastic moduli of hydrous glasses. Near ambient pressure, depolymerization due to OH– reduces VS and G more than VP and KS. VP and KS in both anhydrous and hydrous glasses decrease with increasing pressure up to ~1–2 GPa before increasing with pressure. Above ~1–2 GPa, VP and KS in both hydrous glasses converge with those in AHRG. In particular, VP in HRG-6 crosses over and becomes higher than VP in AHRG. HRG-6 displays lower VS and G than HRG-3 near ambient pressure, but VS and G in these glasses converge above ~2 GPa. Our results show that hydrous rhyolitic glasses with ~2–4 wt% H2Om can be as incompressible as their anhydrous counterpart above ~1.5 GPa. The nonlinear effects of hydration on high-pressure acoustic velocities and elastic moduli of rhyolitic glasses observed here may provide some insight into the behavior of hydrous silicate melts in felsic magma chambers at depth.
Drivers of change in urban water and wastewater tariffs
Authors: Damkjaer Simon 
Published: October 2020

AbstractWater and wastewater tariffs constitute a primary avenue for utilities to generate revenue towards covering the costs associated with water and wastewater service provisions. In the pursuit of achieving global access to safe and affordable water and sanitation, utilities and governments play an important role in regulating and setting combined tariffs, so that they are able to fund the necessary infrastructure while at the same time ensuring that tariffs do not impede on the ability of consumers to access these services. From a survey of 568 cities across 192 countries, this paper examines the main economic and financial drivers of change to regional urban water and wastewater tariffs from 2018 to 2019. Historically, the average global price for water and wastewater services increased from US$ 1.70/m3 in 2011 to US$ 2.16/m3 in 2019, equating to an annual rise in the mean global combined water tariff of ∼3.4%. The analysis indicates that for the studied regions, the financial and economic costs associated with recurring droughts, old infrastructure, subsidy cuts, increasing energy costs and a shift to alternative water resources such as desalination all contribute to changes in tariffs. Further research on the social and political drivers of change in tariffs is needed, in order to provide a holistic understanding of the balance required to be struck between the objectives of affordability and cost-recovery for achieving global access to water and sanitation.
Application of SVM, ANN, GRNN, RF, GP and RT models for predicting discharge coefficients of oblique sluice gates using experimental data

Published: October 2020

AbstractGates are commonly used to adjust water flow in open channels. By using an oblique/inclined gate, the water transferring capacity of open irrigation canals can be increased. Investigation of free and submerged discharge coefficients for inclined sluice gates is the focus of the present study. First an experimental apparatus incorporating an inclined gate was created. The inclined angle (β) and gate opening (a) were experiment variables, and the five inclination angles include: 0° (vertical gate), 15°, 30°, 45° and 60°. Experimental results showed a greater convergence of flow lines under the gate and increasing the gate angle causes the discharge coefficient to increase. Also experiments showed that increasing the submergence rate (yt/a), decreases the inclined gate discharge coefficient. Performance metrics were created for the experimental results. The metrics utilized Gaussian process (GP) regression, support vector machine (SVM), artificial neural networks (ANN), generalized regression neural network (GRNN), random forest (RF) regression and random tree (RT) based models which were used to predict discharge coefficients (Cd) in both submerged and free flow conditions. The model input parameters were the ratio of the upstream water depth to gate opening (y/a) and the inclined angle (β) for free flow and also the submergence rate (yt/a) for submerged flow. The prediction models show that the ANN model in free flow conditions has the following performance metrics: Coefficient of determination, R2= 0.9957, Root Mean Square Error (RMSE) = 0.0044, and Mean Absolute Error (MAE) = 0.0017. The performance metrics for submerged flow conditions were R2 = 0.9922, RMSE = 0.0079 and MAE = 0.0054. The ANN approach is the most accurate model compared to the others.
Clinical Interpretation of Drug Susceptibility Tests in Tuberculosis
Authors: Laniado-Laborín Rafael 
Published: October 2020

:
Prompt and accurate diagnosis of drug resistance is essential for optimal treatment of
drug-resistant tuberculosis. However, only 20% of the more than half a million patients eligible for
the treatment of MDR-TB/RR-TB receive an appropriate drug regimen. Drug-resistant TB regimens
must include a sufficient number of effective medications, a significant challenge for clinicians
worldwide, as most are forced to make therapeutic decisions without any, or very little information
on drug susceptibility testing. Although phenotypic DST is still commonly regarded as the
gold standard for determining M. tuberculosis susceptibility to antituberculosis drugs, it has several
limitations, mainly its prolonged turnaround time. Molecular methods based on M. tuberculosis genomic
DNA sequencing have been developed during the past two decades, to identify the most
common mutations involved in drug resistance. The Xpert
®
MTB/RIF is a real-time polymerase
chain reaction that offers results in less than two hours and has an overall sensitivity for rifampin resistance
of 96% and 98% specificity. Line probe assays (LPAs) are commercial DNA strip-based
tests for detecting the most frequent mutations responsible for resistance to rifampin, isoniazid, fluoroquinolones,
and second-line injectable drugs.

:
Discrepancies between phenotypic and genotyping methods are a problem that the clinician will
face in everyday practice. However, any resistance result (with any type of test) in a person with
risk factors for harboring resistant microorganisms should be considered appropriate while the results
of complementary tests are available.

Published: October 2020

Background:Nature had already engineered various types of nanoparticles (NPs), especially viruses, which can deliver their cargo to the host/targeted cells. The ability to selectively target specific cells offers a significant advantage over the conventional approach. Numerous organic NPs, including native protein cages, virus-like pieces, polymeric saccharides, and liposomes, have been used for the preparation of nanoparticulate. Such nanomaterials have demonstrated better performance and as well as improved biocompatible, devoid of side effects, and stable without any deterioration.Objective:This review discusses current clinical and scientific research on naturally occurring nanomaterials. The review illustrates and updates the tailor-made approaches for selective delivery and targeted medications that require a highaffinity interconnection to the targeted cells.Method:A comprehensive search was performed using keywords for viral nanoparticles, viral particles for drug delivery, viral nanoparticles for molecular imaging, theranostics applications of viral nanoparticles and plant viruses in nanomedicine. We searched in Google Scholar, PubMed, Springer, Medline, and Elsevier from 2000 to till date and by the bibliographic review of all identified articles.Results:The findings demonstrated that structures dependent on nanomaterials might have potential applications in diagnostics, cell marking, comparing agents (computed tomography and magnetic resonance imaging), and antimicrobial drugs, as well as drug delivery structures. However, measures should be taken in order to prevent or mitigate in pharmaceutical or medical applications the toxic impact or incompatibility of nanoparticle-based structures with biological systems.Conclusion:The review provided an overview of the latest advances in nanotechnology, outlining the difficulties and the advantages of in vivo and in vitro structures that are focused on a specific subset of the natural nanomaterials.

Authors: Yamada Janet , Kouri Andrew , Simard Sarah-Nicole , Segovia Stephanie A , Gupta Samir 
Published: October 2020

Background
Electronic patient questionnaires are becoming ubiquitous in health care. To address care gaps that contribute to poor asthma management, we developed the Electronic Asthma Management System, which includes a previsit electronic patient questionnaire linked to a computerized clinical decision support system.

Objective
This study aims to identify the determinants (barriers and enablers) of patient uptake and completion of a previsit mobile health questionnaire.

Methods
We conducted semistructured interviews with adult patients with asthma in Toronto, Canada. After demonstrating the questionnaire, participants completed the questionnaire using their smartphones and were then interviewed regarding perceived barriers and enablers to using and completing the questionnaire. Interview questions were based on the Theoretical Domains Framework to identify the determinants of health-related behavior. We generated themes that addressed the enablers and barriers to the uptake and completion of the questionnaire.

Results
In total, 12 participants were interviewed for saturation. Key enablers were as follows: the questionnaire was easy to complete without additional knowledge or skills and was perceived as a priority and responsibility for patients, use could lead to more efficient and personalized care, completion on one’s own time would be convenient, and uptake and completion could be optimized through patient reminders. Concerns about data security, the usefulness of questionnaire data, the stress of completing it accurately and on time, competing priorities, and preferences to complete the questionnaire on other devices were the main barriers.

Conclusions
The barriers and enablers identified by patients should be addressed by developing implementation strategies to enhance e-questionnaire use and completion by patients. As the use of e-questionnaires grows, our findings will contribute to implementation efforts across settings and diseases.

Sprawl is one of the forms of expansion that has entered the literature of urban management and planning in the last half-century. Iranian cities are very good example for city sprawl and they have experienced this kind of expansion in very short period and very fast. This paper aims to identify, describe, and analyze Shiraz scatter and sprawl development and its resulting functional-structure, this research is based on exploratory, descriptive and analytical methods. Data collection in this research is through the secondary data and fieldwork research techniques. Data analysis demands descriptive and inferential statistics (Pearson regression correlation). This study suggests that since 1952 Shiraz city has experienced rapid growth, continuous and non-continuous. The proportion of scatter and sprawl development with respect to Shiraz expansion increased from 22.02 in 1957-1967 to 72.8 in 1977-2007. There are three period the first rapid development between 1957 and 2967 after that 5 years gap and the next period which is longer from 30 years between 1977 and 2007. This turning points is in two specific periods are as the result of some consequences: Conversion of agricultural function as a predominant economic function in neighboring communities, into multi-functional agricultural function with emphasis upon services; of some of the rural settlements into Shiraz; The development of extended spatial, administrative, economic, social and structural changes in residential part of Shiraz. Therefore, socioeconomic activities are the main cause of urban sprawl in Shiraz and made Shiraz the most attractive place for in Fars Province. Population growth with correlation between degree of Shiraz scatter development and number of people engaged to service sector by 0.9 has caused a dramatically decline in agriculture (-0.8) and industry (-0.811) sectors. As result rapid urban population growth rate correlation by (0.127) and urbanization coefficient (0.726) and it shows urban and rural migration very important role on scatter development.
