Authors: Fernandes Janesline , Vaz Teotone , Anvekar Tushar S. 
Published: October 2021

Abstract
Background
Nanobiomedicines have gained increasing attention for their potential to improve efficacy and are emerging as a promising therapeutic paradigm. Magnetic nanoconjugates loaded with bioactive drugs have the advantage of sustained circulation in the bloodstream and significantly reduced toxicity of therapeutic agents in a precise manner. The well-developed surface chemistry of Fe3O4 has led to the development better tools, promoting them as nanoplatforms with potential technological applications in biomedical sciences.

Results
Fe3O4 phytohybrids with Laxmitaru extract as the primary coating and loaded with Eugenol and Ylang-Ylang essential oils were successfully synthesized. The X-ray diffraction technique has revealed the high purity nanoparticle materials, as no additional impurity peaks were observed. Fourier transform infra-red spectra have confirmed the presence of a primary coating of Laxmitaru extract and a secondary layer of essential oil, as additional peaks and broadening are observed in drug-loaded Fe3O4 nanoparticles. Magnetic susceptibility values indicate the material's superparamagnetic nature. Transmission electron microscopy images have ensured that the particles were spherical, monodispersed, and in the range of 4.30 nm to 13.98 nm. Antimicrobial studies show inhibition zones on the microorganisms S. Aureus and E. Coli with enhanced activity. Drug entrapment efficiency studies revealed the encapsulation of drug molecules onto Fe3O4-Laxmitaru composite. Dynamic light scattering studies confirm the increase in hydrodynamic size, indicating the loading of essential oils and the decrease in polydispersity index ensures monodispersed nanoparticles. The antioxidant study showed the essential oils retained their antioxidant activity even after they were conjugated on Fe3O4-Lax composites.

Conclusions
Laxmitaru phytochemical-coated Fe3O4 nanoparticles were successfully conjugated with Eugenol and Ylang-Ylang essential oils. Our results provide a model therapeutic approach for the development of new alternative strategies for enhancing antimicrobial and antioxidant therapy, with potential advantages in the field of nanobiomedicine.

The impact of medical scribes on emergency physician diagnostic testing and diagnosis charting
Authors: Todd Brett R. , Nelson Lucas N. 
Published: October 2021

Abstract

Objectives
Since the widespread adoption of electronic medical records (EMRs), medical scribes have been increasingly utilized in emergency department (ED) settings to offload the documentation burden of emergency physicians (EPs). Scribes have been shown to increase EP productivity and satisfaction; however, little is known about their effects on the EP’s diagnostic process. We aimed to assess what effect, if any, scribes have on EP diagnostic test ordering and their documentation of differential diagnoses.

Methods
We conducted a retrospective cohort study utilizing a chart review to compare diagnostic practices of EPs working both with and without scribes. We analyzed the number of laboratory and radiologic diagnostic studies ordered per encounter as well as characteristics of differential diagnosis documentation.

Results
Scribes did not affect laboratory studies ordered per encounter (mean 6.31 by scribes vs. 7.35 by EPs, difference −1.04; 95% confidence interval [CI] −2.34 to 0.26) or radiologic studies ordered per encounter (mean 1.49 by scribes vs. 1.39 by EPs, difference 0.10; 95% CI −0.15 to 0.35). Scribes did not affect the frequency of documenting a differential diagnosis or the number of diagnoses considered in each differential, but they were associated with higher word counts in EP differentials (mean 72.29 by scribes vs. 50.00 by EPs, mean difference 22.79; 95% CI 6.77 to 38.81).

Conclusions
Scribe use does not appear to affect EP diagnostic test ordering but may have a small effect on their documentation of differential diagnoses.

Authors: Refaey A. M. , Elnaggar S. , Abdel-Latif S. H. , Hamza A. 
Published: October 2021

Abstract
The nucleate boiling regime and two-phase flow are greater importance to the safety analysis of nuclear reactors. In this study, the boiling heat transfer in nuclear reactor is numerical investigated. The computational fluid dynamics (CFD) code, ANSYS Fluent 17.2 is used and the boiling model is employed. The numerical predictions obtained are compared with the experimental data reported by A. Hamza et al. [9]. An experimental test rig is designed and constructed to investigate the effect of cooling water chemistry control and the material of heater surface. CFD software, allows the detailed analysis of the two-phase flow and heat transfer. In this paper, we evaluate the accuracy of the boiling model implemented in the ANSYS Fluent code. This model is based on the heat flux partitioning approach and accommodates the heat flux due to single-phase convection, quenching and evaporation. The validation carried out of surfactant fluid/vapor two-phase flow inside the 2-D cylindrical boiling vessel. A heated horizontal pipe with stainless steel, Aluminum, and Zircalloy surface materials are used to numerically predict the field temperature and void fraction. Different surfactant concentrations ranging from 0, (pure water) to 1500 ppm, and heat fluxes ranging from 31 to 110 kW/m2 are used. The results of the predicted model depict that the addition of SDS Surfactant and increasing the heat flux improves the coefficient of boiling heat transfer for a given concentration. Also, it was found that the increasing of the concentration of aqueous surfactant solution increases the pool boiling heat transfer coefficient. The aqueous surfactant solution SDS improved the heat transfer coefficient of Aluminum, Zircalloy and stainless steel surface materials by 135%.138% and 120% respectively. The results of the numerical model are nearly in agreement with that measured in experimental.
The evaluation of TRACE/PARCS model for BWR-4 nuclear power plant by startup test transient analyses

Published: October 2021

Abstract
Generally, the thermal hydraulic (TH) codes need the results of Neutron Kinetics (NK) codes providing the reactivity properties to calculate neutron flux. Then the TH codes perform the safety analyses obtaining the responses of pressure, temperature, or water level. Two kinds of different codes calculate different physical behaviors sequentially and separately. Simultaneously computing thermal hydraulic and neutron kinetics behaviors can enhance the accuracy of the analysis. Hence, it is crucial to develop the TH-NK coupled model. This study presents the capability of the TH-NK coupled model, developed by TRACE (TRAC/RELAP Advanced Computational Engine) and PARCS (Purdue Advanced Reactor Core Simulator), for the BWR-4 nuclear power plant. The establishment of the TRACE/PARCS model presented the nodal and component modeling methodologies. This model was used to simulate two startup tests of high power level system transients. Principal system responses, calculated by the TRACE/PARCS model, were compared with the measured data in startup tests and the results of the point kinetic calculation of the TRACE (TRACE/PK) to evaluate the model. The evaluation shows that the TRACE/PARCS model can simulate the interaction between thermal hydraulic and neutron kinetics phenomena and predict the transients suitably. Through the comparison, the TRACE/PARCS model can be confident doing the analyses of normal and abnormal operational transients to predict the transient responses.
Heat transfer characterization under radial jet and falling film induced rewetting
Authors: Kumar M. , Mukhopadhyay D. 
Published: October 2021

Abstract
Empirical correlations are developed for rewetting velocity and maximum heat transfer coefficient during rewetting phase of single hot vertical Fuel Pin Simulator (FPS) by using radial jet impingement and falling film. Emergency Core Cooling System (ECCS) has been designed for Advance Heavy water Reactor (AHWR) to rewet the hot fuel pin under the loss of coolant accident. Coolant injection takes place from a water rod which is located at the center of the fuel bundle in form of jets to rewet hot surface of fuel pin under loss of coolant accident. This kind of design to reflood the fuel bundle is different than bottom and top spray reflooding practiced in PWR and BWR type of nuclear reactors. There are two different kinds of rewetting found during radial jet induced cooling. The first one is due to radial jet impingement and the second one is due to falling film which is below the jet impingement point. Rewetting velocity has been predicted along the length of fuel pin due to radial jet impingement cooling. Temperature of FPS has been varied from 400°C to 700°C with help of different powers supply, simulating decay heat of reactor. A variation of coolant radial jet mass flow rate is from 0.5 lpm to 1.8 lpm. It is considered during ECCS injection. It has been observed from the experiments that rewetting velocity decreases with increasing the clad surface temperature and increases with increasing the coolant mass flow rate. The rewetting velocity in falling film is found to be nearly 1.8 times higher than rewetting velocity predicted in circumferential direction. Further, it is found that maximum heat transfer coefficient increases with increasing the radial jet coolant mass flow rate. The maximum heat transfer coefficient in case of radial jet impingement is found to be nearly 1.5 times the falling film rewetting. Developed correlation predicts the maximum heat transfer coefficient with experimental data well within the error band of ±10%.
Heat transfer at the step of a CANDU calandria during a severe accident
Authors: David R. 
Published: October 2021

Abstract
During the in-vessel stage of a severe accident in a CANDU 6 reactor, decay heat from a collapsed core would be rejected through the calandria walls into the surrounding water. At the step in the calandria wall, the subshell and annular plate meet at a right angle pointing into the calandria. The geometry at this joint could concentrate the exiting heat flux, potentially leading to calandria failure. Finite element analysis is used to study the heat transfer near the welded joint. Different weld profiles, boundary conditions, and decay heat characteristics are considered, and the local concentration of exiting heat flux is calculated.
Criticality analysis for safety-critical software in nuclear power plant distributed control system
Authors: Cui J. , Cai Y. , Wu Y. 
Published: October 2021

Abstract
Software criticality analysis examines the degree of contribution that each individual failure mode of a software component has on the reliability of software. Higher safety integrity levels are assigned to software modules whose failures cause an unacceptable impact on the operation of the system, and these levels require the implementation of more rigorous software quality assurance measures as defined in IEEE Std 1012 and in the customer’s system requirements specification. In this paper, a novel software criticality analysis method is proposed, the results of which can be used to guide the development of newly developed software and the procurement of Commercial-Off-The-Shelf (COTS) software. The software structure is first analyzed and the software is divided into modules according to their functions. Then the criticality levels of software components are preliminarily classified by means of a safety criticality preliminary analysis tree, followed by their verification through the software hazard and operability analysis (HAZOP). Finally, the target Safety Integrity Level (SIL) of each software module is determined based on its criticality level and the overall safety objective (i. e., SIL) of the system it resides in. As an example, this proposed method is applied to a nuclear power plant safety-critical system to demonstrate the detail application process and to verify the feasibility of the method. Compared with the existing software criticality analysis methods, this method has better operability and verifiability, and can be utilized as a technical guidance for the software criticality analysis of nuclear power plant digital control systems.

Abstract
Buffer/backfill materials for radioactive waste disposal sites consist of pure bentonite or bentonite-rock mixtures. In this study, the batch test method was used to obtain the sorption characteristics of important radionuclides such as Cs, Sr and Co on buffer/backfill materials; i. e., mixing Wyoming MX-80 bentonite or local Taiwanese Zhi-Shin bentonite with possible host rock (argillite and granite) in different proportions (0∼100%). The distribution coefficients (Kd) for Cs, Sr and Co were obtained from the experiments. The distribution coefficient for the bentonite-rock mixtures were found, with more than 50% of mixing proportion of bentonite to argillite or granite, to have very similar values to that of pure bentonite. Furthermore, it was clearly found that the sorption of Cs, Sr and Co to bentonite-rock mixtures is decreased as ionic strength of the liquid phase is increased from 0.001M to 1M for NaCl solutions. According to the experimental results, in synthetic groundwater, it is quite convenient and helpful to assess the distribution coefficients (Kd) of Cs, Sr and Co for buffer/backfill materials using batch sorption experiments with bentonite-rock mixtures of fixed mixing proportions.

Die Vertretung ökologischer Interessen in der Sozialpolitik: Konflikt- oder Kooperationspotential in einer Transformation zur Nachhaltigkeit?
Authors: Bohnenberger Katharina , Fritz Martin , Mundt Ingmar , Riousset Pauline 
Published: October 2021

Abstract
Zu einer vorbeugenden Sozialpolitik gehören ein Klima- und Umweltschutz, der umweltbedingte soziale Risiken vermeidet. Dieser Beitrag arbeitet in einer qualitativen Dokumentenanalyse heraus, in welchem Maße Gewerkschaften sowie Wohlfahrtsverbände in Deutschland zwischen 2012 und 2020 sozial-ökologische Ansätze aufgriffen haben. Der theoretische Rahmen basiert dabei auf einer bedürfnistheoretischen Perspektive und fünf interessensorientierten Erklärungsansätzen: 1) die Heterogenität der Interessen innerhalb und zwischen Gewerkschaften sowie Wohlfahrtsverbänden, 2) das Auftreten neuer, globaler Umweltprobleme, 3) eine korporatistische Konfliktlösung durch Produktionswachstum; sowie zwei inhaltliche Verengungen: 4) die Fokussierung auf Erwerbsarbeit und Ausblendung des ökologischen Fußabdrucks von Arbeitsplätzen sowie 5) das Ignorieren des Einflusses aktueller Arbeitsbedingungen auf die Realisierbarkeit ökologischer Lebensweisen. Wir beobachten eine eingeschränkte, ambivalente, jedoch zunehmende Integration sozialökologischer Belange in den Aktivitäten der Interessenvertretungen, die sich in verschiedenen Themenbereichen strukturell unterscheidet. In einem Ausblick diskutieren wir drei mögliche Strategien für die Weiterentwicklung sozialpolitischer Interessenvertretungen angesichts zunehmender ökologischer Herausforderungen.
Die Rolle von Gesundheit und Krankheit im deutschen Armutsdiskurs
Authors: Ariaans Mareike , Reibling Nadine 
Published: October 2021

Abstract
Mit der Veröffentlichung der Armuts- und Reichtumsberichte der Bundesregierung seit 2001 hat sich ein politischer Armutsdiskurs in Deutschland verstetigt. Gesundheit ist in allen bisherigen fünf Berichten eine zentrale Dimension. Jedoch ist für Deutschland bis heute wenig erforscht, welche Rolle Gesundheit in der politischen Debatte zu Armut einnimmt. Aufbauend auf der Medikalisierungstheorie untersuchen wir in diesem Beitrag mit einer qualitativen und quantitativen Inhaltsanalyse, wie Gesundheit und Krankheit in den Berichten dargestellt werden. Über den gesamten Zeitraum wird Armut eher als Ursache von Krankheit gesehen. Der Schwerpunkt der Lösungen für armutsbedingte Krankheiten liegt vor allem auf Verbesserungen des Gesundheitssystems und nicht bei der Armutsbekämpfung. Verhältnisprävention spielt erst in den letzten beiden Berichten eine bedeutsame Rolle. Auch werden gesundheitsbedingte Armutslagen nach dem vierten Armuts- und Reichtumsbericht (2013) weniger individualisiert und stattdessen strukturelle Ursachen wie Arbeitsbedingungen stärker diskutiert.
Wohneigentum, sozialpolitische Einstellungen und Region
Authors: Heide Julian 
Published: October 2021

AbstractSozialpolitische Einstellungen werden oft durch die Position auf dem Arbeitsmarkt erklärt. Dieser Artikel dagegen untersucht eine spezifische Vermögensform, das Wohneigentum, als Erklärungsfaktor für sozialpolitische Präferenzen. Mit Verweis auf die Figur der investiven Statusarbeit wird Wohneigentum als der Mittelschicht eigene Investitionsform eingeführt. Der Artikel differenziert Wohneigentümer/-innen zusätzlich nach dem Wert des Wohneigentums und der Region, in der sich die Immobilie befindet. Mit Daten des ALLBUS 2014 kann gezeigt werden, dass Wohneigentümer/-innen Sozialpolitik grundsätzlich skeptischer gegenüberstehen als Mieter/-innen. Ein höherer Wert des Wohneigentums verringert dabei die Zustimmung zu sozialpolitischen Maßnahmen. Eigentümer/-innen mit Immobilien in peripheren Regionen sind zudem Sozialpolitik gegenüber positiver eingestellt als Personen, deren Eigentum sich in wachsenden Großstädten und deren Umland befindet.

TRABALHO NA AGRICULTURA E POLÍTICA SALARIAL: o caso do Complexo Agroindustrial Canavieiro da Paraíba
Authors: Bezerra Lucas 
Published: October 2021

O artigo discute a política salarial para o trabalho na agricultura praticada pelo Complexo Agroindustrial Canavieiro da Paraíba. O foco são os assalariados rurais inseridos no corte manual da cana-de-açúcar, submetidos às imposições do pagamento por produção. Esta modalidade de salário configura-se enquanto a mais adequada às práticas empresariais em vigência no setor sucroalcooleiro. Em consequência a isso, o texto apresenta a ideia de que a política salarial assentada no pagamento por produção desgasta a vida dos trabalhadores, acirra a exploração, incrementa a taxa de mais-valia e atua como um dispositivo de controle e desmonte do trabalho.
