Vision and Radar Steering Reduces Agricultural Sprayer Operator Stress without Compromising Steering Performance
Authors: Burgers Travis A. , Vanderwerff Kelly J. 
Published: July 2022

HighlightsStress was measured in professional sprayer operators who, while working, drove manually and with vision or radar steering.Vision and radar steering reduced the average operator stress rate by 48% relative to manual steering.The use of automatic guidance could have a dramatic positive effect on the health of sprayer operators.Sprayer steering performance was reported for professional operators and both vision and radar guidance for the first time.Abstract. Self-propelled agricultural sprayer operators work an average of 15 h d-1 in peak season, and steering is the task that causes the operator the most stress because of the large number of stimuli involved. Automatic guidance systems help reduce stress and fatigue for operators by allowing them to focus on tasks other than steering. Physiological signals like skin conductance (electrodermal activity, EDA) change with stress and can be used to identify stressful events. The objective of this study was to determine if using a commercially available vision and radar guidance system (VSN®, Raven Industries) reduces agricultural sprayer operators’ stress compared to when they are steering manually. Four male professional sprayer operators participated in this study. Each operator performed his job duties normally in GPS-guidance-planted fields, at his self-selected speed, except to drive some passes manually and others with VSN in the same field. EDA was measured with an Empatica E4 wristband, and stressful events were quantified. Machine data (e.g., speed, RTK-GPS, and VSN metrics) were collected from each sprayer via CAN logs. The steering type, stress rate (e.g., stressful events min-1), and steering performance (cross-track error standard deviation, XTE SD) were determined for each pass. In total, 51 passes (23 manual, 28 VSN) in six fields were analyzed. Operators using VSN had a significant reduction (48% lower, p &lt; 0.001) in their stress rate compared to when they were steering manually. There was no significant difference in the XTE SD for the steering type. The use of an automatic guidance system such as VSN could have a dramatic positive effect on the health of sprayer operators, especially during the long workdays of the peak spraying season, and could reduce the negative effects that stress and fatigue have on steering performance, mistakes, and accidents.

Published: July 2022

Background
The study was aimed to estimate the true prevalence of human tuberculosis (TB); identify risk factors and clinical symptoms of TB; and detect rifampicin (RIF) sensitivity in three study areas of Bangladesh.

Methods
The cross-sectional study was conducted in three Bangladesh districts during 2018. Potential risk factors, clinical symptoms, and comorbidities were collected from 684 TB suspects. Sputum specimens were examined by LED microscopy. TB hierarchical true prevalence, risk factors and clinical symptoms were estimated and identified using a Bayesian analysis framework. Rifampicin sensitivity of M. tuberculosis (MTB) was detected by GeneXpert MTB/RIF assay.

Results
The median TB true prevalence was 14.2% (3.8; 34.5). Although overall clustering of prevalence was not found, several DOTS centers were identified with high prevalence (22.3% to 43.7%). Risk factors for TB identified (odds ratio) were age (> 25 to 45 years 2.67 (1.09; 6.99), > 45 to 60 years 3.43 (1.38; 9.19) and individuals in families/neighborhoods where a TB patient(s) has (ve) already been present (12.31 (6.79; 22.60)). Fatigue, night sweat, fever and hemoptysis were identified as important clinical symptoms. Seven of the GeneXpert MTB/RIF positive sputum specimens (65) were resistant to rifampicin.

Conclusions
About one in every seven TB suspects was affected with TB. A number of the TB patients carry multi drug resistant MTB. Hierarchical true prevalence estimation allowed identifying DOTS centers with high TB burden. Insights from this study will enable more efficient use of DOTScenters-based TB surveillance to end the TB epidemic in Bangladesh by 2035.
The association between psychological burden related to COVID-19 and addictive social media use: Testing the mediational role of anxious affect
Authors: Vally Zahir , Helmy Mai 
Published: July 2022

Introduction
The COVID-19 pandemic has had a substantial impact on the normalcy of life. Similarly, social media use (SMU) has increased exponentially. This study examined the association between individuals’ perception of the psychological burden related to the pandemic and addictive SMU.

Method
A cross-sectional study was conducted between February and May 2021 in two national contexts, Egypt, and the United Arab Emirates. Data were gathered from a sample of 1322 participants drawn from a university population who completed measures of psychological burden related to COVID-19, anxious affect, and addictive SMU. Preliminary analyses of the potential association between the study variables were conducted using bivariate correlations followed by a pre-specified mediation model.

Results
At a correlational level, all three study variables were positively associated with each other (r values ranged from .18 to .50 and all p values were < .05). A further mediation analysis confirmed that the total effect of psychological burden on addictive SMU was significant (β = .654, SE = .033, 95% CI .589-.720), and this relationship remained significant with inclusion of the mediator. Significant mediation was evident across the total sample as well as within each country-specific subsample.

Conclusion
These results provide insight into the factors that contribute to the development of addictive SMU in relation to the COVID-19 pandemic. Findings are discussed in relation to the emotion regulation function that SMU might play for individuals in the midst of emotional distress.

Zusammenfassung
Eingangs- und Schlussformeln haben erst seit dem letzten Viertel des neunzehnten Jahrhunderts eine größere wissenschaftliche Beachtung gefunden. Da sie mit dem eigentlichen Märchen in keinem Zusammenhang zu stehen scheinen und in einem gewissen Sinne austauschbar sind, hielt man sie nicht für wichtig. Erst die ‚Entdeckung‘ der Erzählerpersönlichkeit, die Aufwertung des lebendigen mündlichen Erzählens und die Einsicht in die Bedeutung des Publikums weckten nachhaltig die Aufmerksamkeit für die vielfältigen Funktionen von Eingangs- und Schlussformeln: Sie stiften Kontakt zum Publikum und animieren es, sich als Hörende und Sehende der in der Erzählung evozierten fiktiven Welt hinzugeben und diese nicht an einer außerhalb der Erzählung liegenden Realität zu messen. Ebenso geben die Schlussformeln das Signal, sich mit dieser Realität wieder abzufinden.

Vernachlässigte Gattungen. Plädoyer für ihre stärkere Gewichtung in der Erzählforschung
Authors: Wehse Rainer 
Published: July 2022

Zusammenfassung
Als Erbin des achtzehnten und neunzehnten Jahrhunderts, als ‚Volkspoesie‘ der höheren Literatur zur Seite gestellt wurde, liegt das Augenmerk der Erzählforschung bis heute eher auf längeren Gattungen. Weniger Aufmerksamkeit dagegen kam und kommt den Klein- und Kleinstgattungen zu. Der Aufsatz plädiert für eine stärkere Beachtung dieser kleinen und weithin vernachlässigten Formen – einem vergnüglichen Biotop, dem hier durch zahlreiche Beispiele Reverenz erwiesen wird und dem viele wichtige Funktionen zu eigen sind.
Green synthesis of nano-propolis and nanoparticles (Se and Ag) from ethanolic extract of propolis, their biochemical characterization: A review
Authors: Barsola Bindiya , Kumari Priyanka 
Published: July 2022

Abstract
Propolis is a natural bee product with phenolic components and flavonoid content. As propolis is hydrophobic, it is poorly absorbed by the body, querying the use of other technologies. This review focuses on the biosynthesis, characterization, and evaluation of some biological activities of nanoparticles (AgNPs and SeNPs). The nanoparticles were generated utilizing bee propolis extract, taking into account the benefits of green nanoparticle synthesis. Due to the smaller size, nano-propolis is more easily absorbed by the body. Nano-propolis has the potential to improve efficacy in the realms of medicine and biology. Green chemistry approach to nanoparticle synthesis offers several advantages, including process scaling, economic feasibility, and a safe technique to make nanoparticles. Bioreduced AgNPs can be employed as a therapeutic agent to treat a variety of human ailments. After deeply studying and reviewing different research studies, it was evaluated that the natural nanoparticles have the potential to be effective in the treatment of bacterial and fungal infections.
The impact of evaluation and qualification criteria on Iraqi electromechanical power plants in construction contracts
Authors: Noori Hamza Hamza , Rasheed Sawsan 
Published: July 2022

Abstract
The Ministry of Electricity (MoE) is one of Iraq’s most significant sectoral ministries. Despite massive amount invested in power generation, the country is plagued by power outages for more than three decades. One of the most common sources of the problem and significant impact on the waste of public funds in contractual processes. The Ministry of Planning issued regulations and procedures to facilitate the implementation of power plants by applying the sectorial standard bidding documents (SSBD) of design, supply, and installation of the electromechanical project to support MoE by developing economic projects that lead to raising Iraqi electricity generation field. The research evaluates the government evaluation procedures applied in SSBD and their impact on Iraqi power plant contracts. The study’s principal data gathering approaches via interviews with consultants resulted in a structured questionnaire that includes 25 criteria delivered to MoE’s senior staff. One hundred respondents out of 120. The relative importance index was applied to rank and match respondent consensus on the relevance of the 25 factors. This article’s primary conclusion is weak evaluation of SSBD criteria and inadequate bid evaluations, resulting in an ineffective procurement system, and the results aim to encourage MoE’s decision-makers to optimize the criteria.
Tanshinone IIA reverses oxaliplatin resistance in colorectal cancer through microRNA-30b-5p/AVEN axis
Authors: Ge Tingrui , Zhang Yonggang 
Published: July 2022

Abstract
This research aims to explore the role of Tanshinone IIA (Tan IIA) and microRNA (miR)-30b-5p in chemoresistance of colorectal cancer (CRC). The expression levels of miR-30b-5p and apoptosis and caspase activation inhibitor (AVEN) was detected by reverse transcription-quantitative polymerase chain reaction assay. The cell proliferation and apoptosis were examined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and flow cytometry assays. The target relationship between miR-30b-5p and AVEN was confirmed by Dual-luciferase reporter assay. Transwell assay was performed to assess CRC cells’ metastasis. Western blot was carried out to measure the apoptosis-related protein. The results showed that miR-30b-5p was lowly expressed in oxaliplatin-resistance CRC cells SW480 (SW480/R) compared to SW480 cells. Overexpression of miR-30b-5p significantly suppressed the malignant biological behaviors of SW480/R cells and significantly promoted the sensitivity of SW480/R cells to oxaliplatin by down-regulated AVEN expression. Besides, Tan IIA treatment upregulated miR-30b-5p expression in SW480/R cells. Moreover, miR-30b-5p upregulation strengthened the promoting effect of Tan IIA on the sensitivity of SW480/R cells to oxaliplatin. In conclusion, Tan IIA and miR-30b-5p could reverse oxaliplatin resistance of CRC cells and may thus be potential treatment strategies for treating patients with CRC.

Abstract

Objectives
This study aimed to evaluate the effect size of each parameter used in the first trimester Down syndrome (DS) risk analyses by using multiple regression analysis techniques.

Methods
This data mining study included data of 44,260 pregnant women screened at the Acibadem Labmed laboratories from 2010 to 2019. In this study, risk was calculated using the PRISCA software on the basis of nuchal translucency (NT), crown-rump length measurement, in vitro fertilization application, diabetes mellitus, Down syndrome story, smoking, maternal age, and the level of maternal serum biochemistry markers including pregnancy-associated plasma protein-A (PAPP-A) and free beta-human chorionic gonadotropin (hCGβ).

Results
Forty-four thousand two hundred sixty risk analysis patients result data were re-investigate, and 851 (1.93%) risk analysis results were found as positive. PAPP-A 747 (CI%, 476–1,170) times, NT value 512 (CI%, 343–764) times, DS story 21 times (CI%, 6.7–63.2) and hCGβ value 7.01 (CI%, 6.31–7.79) times affect the combined first-trimester risk analysis results.

Conclusions
We have suggested that those accurate PAPP-A levels and NT levels evaluation are the most critical point of combined risk analysis and that the risk of free hCGβ levels after PAPP-A is essential as a biochemical test.
Historical revivalism in hungarian country house gardens between 1880 and 1930: An exploration and analysis
Authors: Alföldy Gábor 
Published: July 2022

The period lasting from the Compromise betweeen Austria and Hungary in 1867 to World War I was a ‘golden age’ of Hungarian horticulture and garden art. Country houses with their parks belonged traditionally to the way of living of the aristocracy. The ‘construction boom’ generated by a fruitful interplay of the favourable economic conditions of the ‘Gründerzeit’ and the related social needs and financial abilities, resulted in a multitude of new gardens. This surge of development almost coincided with the spread of historical revivalism in garden design from the 1860s and with an increasing role played by Hungarian creators of gardens in addition to foreign specialists who settled or were invited to work here.The period between the two World Wars did not effect a fatal break in this garden culture. In some cases, this slowly consolidating period brought real efflorescence (e.g. Hatvan, Röjtökmuzsaj, Szeleste), though these places were the exceptions. The construction and transformation of parks together with the modernization of houses continued in the interwar decades (e.g. Dég, Röjtökmuzsaj) and considerable new establishments were also created (e.g. Vajta, Csorvás, Selyp).The country house gardens of historical revivalism, with their spectacular parterres, avenues, exotic plant rarities grown in the greenhouses or nursery gardens and transferred to the pleasure-grounds or shown at exhibitions, with their sports facilities and family mausoleums represented the prestige of the aristocracy which still clearly played the leading role in politics and society despite their declining economic and cultural influence. Alternatively they expressed the ambition of a new plutocracy to acquire social legitimation for their wealth. In a few cases and in both groups, there was something else: the garden became the site and instrument through which they could achieve accomplishment by means of creative activity.The present study is a first attempt at summarising the partial results of research that in its initial phase on the topic. It describes 12 sites in detail, 9 from the period between 1880 and World War I, and 3 from the 1920–30s. After the descripions it gives a preliminary overview of tendences and characteristics of the examined period including the transformation of the landscape garden, revivalist structural elements, follies and utilitarian garden structures, statuary and other garden ornaments, landscape gardeners and creative owners, mainteneance and productive gardening, with a lot of further examples and personalities. Finally, a brief outlook closes the study to the post-1945 survival of the gardens described and historical revivalism in garden art in general.
Additive manufacturing: Frameworks for chemical understanding and advancement in vat photopolymerization
Authors: Schwartz Johanna J. 
Published: July 2022

AbstractThree-dimensional printing, or additive manufacturing (AM), is a broad term for a wide range of fabrication methods utilizing materials such as small-molecule, polymer, and metal feedstocks. Each method requires different chemical, physical, and engineering needs to be successful. This article will discuss some of the considerations for polymer-based AM methods. Ultimately, we focus on the chemistries of vat photopolymerization, in which light is used to cure a resin from liquid to solid, to provide an example of how chemical advancements have led to increased speed, resolution, and multimaterial printing capabilities not previously possible.

The 8 April 1860 Jour de Pâques Earthquake Sequence in Southern Haiti
Authors: Martin Stacey S. , Hough Susan E. 
Published: July 2022

ABSTRACT
The grave threat posed by the Enriquillo-Plantain Garden fault zone (EPGFZ) and other fault systems on the Tiburon Peninsula in southern Haiti was highlighted by the catastrophic M 7.0 Léogâne earthquake on 12 January 2010 and again by the deadly M 7.2 Nippes earthquakes on 14 August 2021. Early Interferometric Synthetic Aperture Radar observations suggest the 2021 earthquake broke structures associated with this fault system farther west of the 2010 event, but the rupture zones of both events are separated by a ∼50 km gap. This sequence provided the impetus to reconsider a nineteenth century earthquake that may have occurred within this gap. Though previous studies identified a single moderately large event on 8 April 1860, original sources describe a complex and distributed seismic sequence to the west of Port-au-Prince. These provide evidence for an initial event to the west of Les Cayes, on the southern coast of the Tiburon Peninsula. This was followed on the morning of 8 April 1860 by a damaging earthquake near l’Anse-à-Veau along the northern coast of the peninsula, which was succeeded 14 hr later by a larger mainshock to the east. Although locations cannot be determined precisely from extant macroseismic data, our preferred scenario includes an intensity magnitude (MI)∼6.2 foreshock, followed by an MI∼6.8 mainshock wholly or partially on the EPGFZ to the east of the foreshock. Our results suggest that, although earthquakes tend to trigger subsequent earthquakes on immediately neighboring fault segments, sequences can include gaps due to strain release by poorly characterized earthquakes in the historic past. We also document 83 aftershocks to the 1860 earthquake sequence, including a previously unknown damaging shock, estimated MI∼6.6, on 10 April 1860 near Jérémie, farther west of l’Anse-à-Veau.
A Python Code for Detecting True Repeating Earthquakes from Self-Similar Waveforms (FINDRES)
Authors: Sugan Monica , Campanella Stefano , Vuan Alessandro , Shakibay Senobari Nader 
Published: July 2022

AbstractSeismic data are generally scrutinized for repeating earthquakes (REs) to evaluate slip rates, changes in the mechanical properties of a fault zone, and accelerating nucleation processes in foreshock and aftershock sequences. They are also used to study velocity changes in the medium, earthquake physics and prediction, and for constraining creep rate models at depth. For a robust detection of repeaters, multiple constraints and different parameter configurations related to waveform similarity have been proposed to measure cross-correlation values at a local seismic network and evaluate the location of overlapping sources. In this work, we developed a Python code to identify REs (FINDRES), inspired by previous literature, which combines both seismic waveform similarity and differential S-P travel time measured at each seismic station. A cross-spectral method is applied to evaluate precise differential arrival travel times between earthquake pairs, allowing a subsample precision and increasing the capacity to resolve an overlapping common source radius. FINDRES is versatile and works with and without P- and S-wave phase pickings, and has been validated using synthetic and real data, and provides reliable results. It would contribute to the implementation of open-source Python packages in seismology, supporting the activities of researchers and the reproducibility of scientific results.
