COVID-19 Surveillance Updates in US Metropolitan Areas: Dynamic Panel Data Modeling
Authors: Oehmke Theresa B , Moss Charles B , Oehmke James F 
Published: November 2021

Background
Despite the availability of vaccines, the US incidence of new COVID-19 cases per day nearly doubled from the beginning of July to the end of August 2021, fueled largely by the rapid spread of the Delta variant. While the “Delta wave” appears to have peaked nationally, some states and municipalities continue to see elevated numbers of new cases. Vigilant surveillance including at a metropolitan level can help identify any reignition and validate continued and strong public health policy responses in problem localities.

Objective
This surveillance report aimed to provide up-to-date information for the 25 largest US metropolitan areas about the rapidity of descent in the number of new cases following the Delta wave peak, as well as any potential reignition of the pandemic associated with declining vaccine effectiveness over time, new variants, or other factors.

Methods
COVID-19 pandemic dynamics for the 25 largest US metropolitan areas were analyzed through September 19, 2021, using novel metrics of speed, acceleration, jerk, and 7-day persistence, calculated from the observed data on the cumulative number of cases as reported by USAFacts. Statistical analysis was conducted using dynamic panel data models estimated with the Arellano-Bond regression techniques. The results are presented in tabular and graphic forms for visual interpretation.

Results
On average, speed in the 25 largest US metropolitan areas declined from 34 new cases per day per 100,000 population, during the week ending August 15, 2021, to 29 new cases per day per 100,000 population, during the week ending September 19, 2021. This average masks important differences across metropolitan areas. For example, Miami’s speed decreased from 105 for the week ending August 15, 2021, to 40 for the week ending September 19, 2021. Los Angeles, San Francisco, Riverside, and San Diego had decreasing speed over the sample period and ended with single-digit speeds for the week ending September 19, 2021. However, Boston, Washington DC, Detroit, Minneapolis, Denver, and Charlotte all had their highest speed of the sample during the week ending September 19, 2021. These cities, as well as Houston and Baltimore, had positive acceleration for the week ending September 19, 2021.

Conclusions
There is great variation in epidemiological curves across US metropolitan areas, including increasing numbers of new cases in 8 of the largest 25 metropolitan areas for the week ending September 19, 2021. These trends, including the possibility of waning vaccine effectiveness and the emergence of resistant variants, strongly indicate the need for continued surveillance and perhaps a return to more restrictive public health guidelines for some areas.

Published: November 2021

The antimicrobial resistance has more impact on the health care division which would increase the mortality and hospital readmission duration. Our objective is to assess the community pharmacist’s knowledge on dispensing of antimicrobial drugs and prevention of antimicrobial resistance in community practice. A cross-sectional study was conducted for six months. A sample size of 150 registered community pharmacists participated in the study. We have used simple random techniques to select the community pharmacists. Questionnaire were distributed to the community pharmacists at pre and post visits and the response was analyzed. The collected data was analyzed using graph pad prism software. The mean and standard deviation was calculated and P<0.005 was considered to be statistically significant. For 25-30 years of age , community pharmacists were more 68 (45.33%) as compared to other ages. Pre visit before and after average mean antimicrobial resistance score was found to be 4.87. Proper implementation of antimicrobial resistance prevention programmes would drastically increases the rational use of antimicrobials could and minimizes the health care cost.
Defect induced cracking and modeling of fatigue strength for an additively manufactured Ti-6Al-4V alloy in very high cycle fatigue regime
Authors: Chi Weiqian , Wang Wenjing , Sun Chengqi 
Published: November 2021

Additively manufactured (AM) alloy usually inevitably contains defects
during the manufacturing processor or service process. Defects, as a
harmful factor, could significantly reduce the fatigue performance of
materials. This paper shows that the location and introduced form of
defects play an important role in high cycle and very high cycle fatigue
(VHCF) behavior of selective laser melting Ti-6Al-4V alloy. S-N curve
descends linearly for internal defects induced failure. While for
artificial surface defects induced failure, S-N curve descends at first
and then exhibits a plateau region feature. We also observed
competition of interior crack initiation with the fine granular area
feature in VHCF regime. The paper indicates that only the size or the
stress intensity factor range of the defect is not an appropriate
parameter describing the effect of defects on the fatigue crack
initiation. Finally, the effect of artificial surface defects on high
cycle and VHCF strength is modeled, i.e. the fatigue strength
σ, fatigue life N and defect
size area (square root of projection area of defect
perpendicular to principal stress direction) is expressed as σ =
CN ( area)
for N and
σ = CN (
area) for
N≥N, where C, a and
n are constants, N is the number of
cycles at the knee point.

Application of Magnetic and Ultrasonic Methods for Determining Parameters of Ferromagnetic Components in Iron Ore Slurry Flows
Authors: Morkun Vladimir , Morkun Natalia , Tron Vitaliy , Porkuian Olga , Serdiuk Oleksandra , Sulyma Tetiana 
Published: November 2021

AbstractThe article considers the method for controlling the ferromagnetic component content in slurry flow by ultrasonic and magnetic measurements. One of the basic factors determining the efficiency of magnetic separators at iron ore concentration plants is the quality of distribution of the ground ore into the product containing the ferromagnetic component and the waste rock. Due to the fact that in most cases, magnetic separators extract minerals with strongly magnetic properties, it is essential to find the magnetic component content in the input ore and products of its distribution in order to improve control over the technological process. Currently, low accuracy and reliability make existing means of operative control over the ferromagnetic component content in the slurry flow inefficient. Density of slurry is one of the primary disturbing factors affecting the accuracy of measurements, and this fact determines the necessity of measuring this parameter while controlling the ferromagnetic component content. Combined methods of measurements are a promising trend in designing sensors of useful component content in the slurry flow. The article describes the method for controlling the ferromagnetic component content in slurry flow by ultrasonic and magnetic measurements.
Detecting Post-Nuclear Crisis in Hanna Jameson’sThe Last
Authors: Zsámba Renáta 
Published: November 2021

AbstractHanna Jameson’s post-apocalyptic detective novel,The Last(2019), addresses contemporary issues that affect us on both a collective and an individual level. The author diagnoses the denial of nuclearism and calls for an awareness of the nuclear age combined with the looming threat of climate change. The novel negotiates alternative strategies for the treatment of crisis brought about by the nuclear attack and borrows many of the thematic and structural elements from twentieth-century nuclear fictions in which the apocalypse is not necessarily regarded in negative terms but as a chance for regeneration. The events of the post-nuclear months in a Swiss hotel are narrated by an American historian whose written account serves several goals. It gives the illusion of delaying crisis, but it also reveals his fears and traumas conjured up by radioactive spectres. There are two different types of narratives at work, the narrative of the crisis and that of the investigation. The narrator-protagonist becomes obsessed with finding the solution to a murder mystery, which in a metaphorical sense is to give a soothing answer to the death of millions. However, this attempt keeps failing, and thus the narrative of the crisis devours all kinds of rational initiatives to resolve chaos. In order to elaborate on the psychological impact of the post-nuclear crisis in subject construction, I do not only examine the character of the amateur detective of the whodunit whose intervention aims to restore order, but I also apply Gabriele Schwab’s concepts of post-nuclear subjectivity and nuclear hauntology.
Histamine contents in raw long-ripening meat products commercially available in Poland
Authors: Michalski Mirosław , Pawul-Gruba Marzena , Madejska Anna 
Published: November 2021

Abstract

Introduction
Many consumers seek long-ripening meat products. The availability of these highly distinctive cured pork varieties is continuously expanding and their safety should be subject to monitoring. One of potentially harmful substances in these products is histamine. The presence of this toxic amine is reported in many countries, even in high concentrations. However, the EU has not regulated the permissible histamine content in meat, in a situation at odds with that of regulated fish and fish products. This study established the usefulness of biogenic amine testing in long-ripening pork and furnished indicative concentrations potential useful as a background for future research in preparation for EU regulative intervention.

Material and Methods
A total of 97 samples of long-ripening meat products untreated by heat were bought from various shops in the Puławy and Lublin regions of Poland and tested for the presence of histamine using high-performance liquid chromatography with diode array.

Results
The histamine concentration ranged from below limit of detection to 346.64 mg/kg, where 3.47 mg/kg was the lowest in a positive sample. Histamine was detected in 48 samples (49.5%). The maximum amount of histamine was identified in dry ham and the minimum in traditional salami.

Conclusion
The results of this study suggest that testing meat products for biogenic amines should be a very good indicator of the food safety of long-ripening meats. In half of the tested products, levels of biogenic amines potentially toxic to consumers were determined.

Abstract
The present study attempts to assess the composition, abundance and diversity of avifauna with respect to their habitat in and around the Purbasthali wetland, based on both primary data collected through the point count method during 2017–2019 and literature data. Among the total 77 species (encompassing 10 orders and 19 families), 39 species are migrants, 18 are rare and 24 species show declining global trend. According to their habitat, they are sub-divided into three categories i.e. waterfowls (live in open water, 20 species), waders (live in bank areas/water edge area, 45 species) and wetland associated (live in nearby trees, 12 species). The Shannon-Wiener Diversity Index (H’) and the Evenness Index (E’) are used to examine the diversity within and between the habitats. The result reveals higher diversity and evenness of the waders in comparison to others. The maximum diversity (H′=3.02) and evenness (E′=0.79) has been recorded for the waders in 2019, whereas the least values (H′=1.02, E′=0.34) have been found in 2016 for the waterfowls. Relative Diversity Index affirms the dominance of the Anatidae family. The birds of the area have now been seriously threatened by human intervention.

Published: November 2021

Abstract
The spatial ecology of the Eurasian Griffon Vulture (Gyps fulvus) has been a subject of scientific interest for long due to its conservation status, critical ecosystem role, gregarious lifestyle and complex foraging behavior. The trans-border Eastern Rhodope Mountain in Bulgaria and Greece holds an increasing population of the species and one of the largest on the Balkan Peninsula. We used high-frequency GPS data from 13 Griffon Vultures from this population to study their movements, home range size and its seasonal or age specific dynamics. The overall foraging home range (95% kernel) was 3,204 km2 and the core area of activity (50% kernel) was 256.5 km2. We found high seasonal variation of the home range size. Vultures were foraging over larger areas in the summer and spring but their activity was limited to four times smaller areas in winter. We found no age specific variation in the home range sizes but the non-adult vultures showed tendency to conduct exploratory movements far from the breeding colony. Our results can be used for planning conservation efforts in the areas of high importance for the species.
Different Class Citizens: Understanding the Relationship between Socio-economic Inequality and Voting Abstention
Authors: Ehs Tamara , Zandonella Martina 
Published: November 2021

Abstract
In most established democracies the turnout gap along class lines has increased substantially since the 1980s. Political participation has become a question of resources: income, property, formal education, secure employment and overall social status determine citizens’ engagement in political decision-making. Using a mixed methods approach, our case-study shows that this also applies to Vienna – an overall rich city with a long tradition of social reform policies, often credited with the highest quality of life in the world. Although Vienna still has a relatively high turnout by international standards, political participation is very unevenly distributed once socio-economic resources are taken into account. Thereby and throughout life, class shapes people’s experiences with and as part of democracy. These experiences in turn have long-term effects on their trust in the political system and on their political self-efficacy. Our findings first and foremost contribute to the ongoing debate on democracy’s social imbalance and show that its consequences already apply on the regional level. The study additionally highlights the usefulness of mixed methods approaches when we aim at a better understanding of the class-based turnout gap.
