Evaluating the implementation of an active learning platform in a team-based learning postgraduate Medical Program
Authors: Lee Irene , Wilcox Helen 
Published: October 2022

“Active learning is generally defined as any instructional method that engages students in the learning process. In short, active learning requires students to do meaningful learning activities and think about what they are doing” (Prince, 2004). Basing his definition on foundational work done by Bonwell and Eison (Bonwell, 2000 and Eison, 2010), this definition of active learning has been widely accepted. In the first decade of the 21st century, notwithstanding educational technological tools were not as ubiquitous as it is now, strategies for active learning have already been developed to help direct teachers to better plan their lesson to incorporate such style of learning. The advancement of technology vis-a?-vis the proliferation of student response applications have revolutionized the way such learning is captured in the classroom.
This paper presents a context of a Medical School in the Faculty of Health, Medical Sciences (FHMS) of the University of Western Australia (UWA) undergoing changes to its cased-based learning (CBL) curriculum to a more time-efficient Team-based (TBL) one. At about the same time, there was an institution-wide implementation of an active learning platform in the institution. Juxtaposing the two elements led to this preliminary study of capturing student’s active learning in a Team-based context using the Analytic Dashboard from the active learning platform. Student engagement scores captured in the dashboard were very positive and the use of Eric Mazur Concept Testing Model helped achieve the active learning goals of the TBL sessions. Moving forward, future iterations of team-based learning sessions with the active learning platform could be deployed in other schools within FHMS that have case-based studies (CBL) in their curriculum and compared them to the TBL practice in Medical School.

Abstract

Objectives
Hepatic arterial buffer response (HABR) is an important regulatory process for hepatic blood flow. Its activity has been described in some fetal adverse conditions but in twin-to-twin transfusion syndrome (TTTS) it is unknown if such response is present. The aim of this study is to test the hypothesis that HABR operates in monochorionic diamniotic twins (MCDA) with TTTS.

Methods
Hepatic artery pulsatility index (PI) and peak systolic velocity (PSV) were measured prospectively in 64 MCDA pregnancies. 43 without TTTS (group 1) and in 21 pregnancies with TTTS (group 2). We calculated ratios for PI (HAPI-ratio) and PSV (HAV-ratio) between recipient and donor in group 2 or bigger and smaller fetus in group 1 and compared groups. The association of HAV-ratio and HAPI ratio with TTTS, relation with other fetal Dopplers and reliability of measurement by a single operator were investigated.

Results
HAV-ratio and HAPI-ratio appears to be independent from fetal Dopplers, estimated weight and gestational age. In group 2, HAV-ratio is lower than group 1 (p<0.001, 95% CI 0.443–0.643). In group 1 the mean HAV-ratio is 1.014 (±0.021) while in group 2 is 0.47 (±0.035). HAPI-ratio is lower in group 2 than in group 1 although this difference was not significant (p=0.066, 95% CI −0.007–0.231). A good reliability of measurements of hepatic artery PSV and PI was demonstrated by intraclass correlation coefficient analysis (ICC 0.971 95% CI 0.963–0.977, p<0.001 and ICC 0.694 95% CI 0.596–0.772, p<0.001, respectively).

Conclusions
Monochorionic pregnancies with TTTS are associated with lower HAV-ratios. This could be explained by an active HABR.

Abstract
Plasmonic nanoantennas have been extensively explored to boost nonlinear optical processes due to their capabilities to confine optical fields on the nanoscale. In harmonic generation, nanoantenna array architectures are often employed to increase the number of emitters in order to efficiently enhance the harmonic emission. A small laser focus spot on the nanoantenna array maximizes the harmonic yield since it scales nonlinearly with the incident laser intensity. However, the nonlinear yield of the nanoantennas lying at the boundary of a focused beam may exhibit significant deviations in comparison to those at the center of the beam due to the Gaussian intensity distribution of the beam. This spatial beam inhomogeneity can cause power instability of the emitted harmonics when the lateral beam position is not stable which we observed in plasmon-enhanced third-harmonic generation (THG). Hence, we propose a method for deterministically designing the density of a nanoantenna array to decrease the instability of the beam position-dependent THG yield. This method is based on reducing the ratio between the number of ambiguous nanoantennas located at the beam boundary and the total number of nanoantennas within the beam diameter to increase the plasmon-enhanced THG stability, which we term as the ratio of ambiguity (ROA). We find that the coefficient of variation of the measured plasmonic THG yield enhancement decreases with the ROA. Thus, our method is beneficial for designing reliable sensors or nonlinear optical devices consisting of nanoantenna arrays for enhancing output signals.

AbstractArabica coffee plantation area is limited, and production is still low while demand increases. The development of Arabica coffee in Indonesia faces many obstacles that threaten its sustainability. The objective of this study is to determine the sustainability status of the Arabica coffee business in West Java and formulate a sustainability strategy. Primary data were obtained through interviews with respondents and key persons from relevant stakeholders from upstream to downstream using a structured questionnaire. The study was conducted in August‒October 2021 in Garut District, West Java. Multidimensional Scaling (MDS) was used to assess the sustainability status of the Arabica coffee business in five dimensions, i.e., ecological, economic, social, marketing, and institutional. The results show that the Arabica coffee business in West Java is fairly sustainable, with an average score of 55.65%. The MDS analysis for each dimension reveals that the social dimension has the highest score (62.45%), followed by the ecological dimension (59.01%), the economic dimension (53.00%), the institutional dimension (51.92%), and the marketing dimension (51.87%). This study emphasizes five actions as parts of the sustainability strategy, i.e., adaptation and mitigation of climate change, creative efforts to increase farmers’ income, human resource capacity building, strengthening business partnerships, and strengthening farmer organizations.

Abstract
Chain polymerizations are defined as chain reactions where the propagation steps occur by reaction between monomer(s) and active site(s) on the polymer chains with regeneration of the active site(s) at each step. Many forms of chain polymerization can be distinguished according to the mechanism of the propagation step (e.g., cyclopolymerization – when rings are formed, condensative chain polymerization – when propagation is a condensation reaction, group-transfer polymerization, polyinsertion, ring-opening polymerization – when rings are opened), whether they involve a termination step or not (e.g., living polymerization – when termination is absent, reversible-deactivation polymerization), whether a transfer step is involved (e.g., degenerative-transfer polymerization), and the type of chain carrier or active site (e.g., radical, ion, electrophile, nucleophile, coordination complex). The objective of this document is to provide a language for describing chain polymerizations that is both readily understandable and self-consistent, and which covers recent developments in this rapidly evolving field.

Abstract
This paper presents the characterization of the microstructure evolution during flow forming of austenitic stainless steel AISI 304L. Due to plastic deformation of metastable austenitic steel, phase transformation from γ-austenite into α’-martensite occurs. This is initiated by the formation of shear bands as product of the external stresses. By means of coupled microscopic and micromagnetic investigations, a characterization of the microstructure was carried out. In particular, this study shows the distribution of the strain-induced α’-martensite and its influence on material properties like hardness at different depths. The microstructural analyses by means of electron backscattered diffraction (EBSD) technique, evidence a higher amount of α’-martensite (ca. 23 %) close to the outer specimen surface, where the plastic deformation and the direct contact with the forming tool take place. In the middle area (ca. 1.5 mm depth from the outer surface), the portion of transformed α’-martensite drops to 7 % and in the inner surface to 2 %. These results are well correlated with microhardness and micromagnetic measurements at different depths. EBSD and atomic force microscopy (AFM) were used to make a detailed characterization of the topography and degree of deformation of the shear bands. Likewise, the mechanisms of nucleation of α’-martensite were discussed. This research contributes to the development of micromagnetic sensors to monitor the evolution of properties during flow forming. This makes them more suitable for closed-loop property control, which offers possibilities for an application-oriented and more efficient production.
Segmented chip formation during machining under the influence of different atmospheres
Authors: Schaper F. , Lengacker B. 
Published: October 2022

Abstract
High temperatures and a pronounced segmented chip are characteristic of titanium machining processes. The formation of segmented chips induces an alternating high frequency mechanical load on the tool and thus promotes tool failure. The presence of oxygen triggers a multitude of chemical interactions during the chip forming process. However, the oxygen content’s impact during titanium machining, especially on the chip formation, is unknown. In order to draw conclusions on this process, the machining tests were carried out while varying the oxygen content. The thus produced chips were metallographically examined. The varying degree of segmentation could then be visualized by boundary etching and subsequently be evaluated.
Magnetic fluid flow and heat transfer due to a uniform source and vorticity
Authors: Bhandari Anupam 
Published: October 2022

Abstract
The present work investigates the ferrohydrodynamic flow and heat transfer due to a uniform source and irrotational vortex under the influence of a stationary magnetic field. A uniform source generates only a two-dimensional flow. However, in the presence of the vorticity with a uniform source, the flow becomes three-dimensional. The governing equations are expressed as a system of nonlinear coupled differential equations. The transformed differential equations are solved using the finite element approach for both the two-dimensional and three-dimensional flow models. With variations in the strength of the source parameter, Reynolds number, and ferromagnetic interaction numbers, the behavior of two-dimensional and three-dimensional flow is investigated. In three-dimensional flow, the influence of swirling effects on the velocity and temperature profiles are weak as compared to two-dimensional flow. The main role of the three-dimensional vortex flow of ferrofluid is to generate rotational viscosity, and it is not possible in the case of two-dimensional flow case.
Semimetal transition in curved MoS2/MoSe2 Van der Waals heterojunction by dispersion-corrected density functional theory
Authors: López-Galán Oscar A. , Ramos Manuel 
Published: October 2022

AbstractWe present a theoretical study for MoS2/MoSe2 Van der Waals heterojunction in the armchair direction, and periodicity in the y-direction, under the mechanical deformation process to explore electronic structure vs. curvature angle. Our findings reveal that the heterojunction maintains chemical stability, even under high deformation, and the bandgap of the heterojunction is inversely proportional to curvature angle; the shift from semiconductor—with a bandgap of 0.8 eV—to semimetal occurs at deformation angles as low as 5°, having a gapless material. The mentioned transition corresponds mainly to distortion of half-filled molybdenum d-orbitals and chalcogen–chalcogen p-orbitals overlapping near the Fermi level.

Authors: Ferdosipour Atefeh , Mojaveri Maryam 
Published: October 2022

This study aims to model job burnout based on job exhaustion and personality traits among the employees. Burnout is a problem caused by workplace tensions. The present research was conducted on 100 employees. The statistical population of the research consisted of all the employees. For field data collection, the Maslach Burnout Inventory, developed by Maslach and Jackson, and NEO personality inventory were used. For data analysis, descriptive statistics (mean and standard deviation) and inferential statistics (correlation and regression) along with SPSS software were employed. The present research hypothesises that there is a significant relationship between job burnout based on job performance, job exhaustion and personality traits among the employees. According to findings, mental exercise, improving psychological satisfaction and experiential freshness can increase conscientiousness and agreeability and decrease neuroticism, which eventually leads to lower burnout.

Published: October 2022

Abstract
Artificial lift systems (ALS) are among the most extensively used production techniques in global oil and gas operations. Wells that cannot produce liquids to the surface through their own pressure require lift technologies to enable the production. In this study, a poor-boy gas lifted well was replaced with a jet pumping system to enhance the production. The software analysis, jet pump (JP) installation, and operational results are presented to validate the utilization of technology.
The candidate well was spud in October 1983 and produced an average of 3,200 BOPD and 1,000 BWPD at flowing wellhead pressure (FWHP) of 2,300 psi from two formations with a slotted-liner in an open hole. However, due to an increase in water production and excessive drop in the FWHP, oil production dropped to zero. The well was brought back to production with the help of a poor-boy gas lift system after making hole punches in the tubing string. But it flowed intermittently with marginal production. A jet pump was recommended as the best lift method based on the technical analysis for ALS. The JP can easily handle a wide range of production and doesn't require rig assistance for JP retrieval and overhauling in case of any changes in future wellbore conditions. Therefore, the well was reconstructed with a 5 inch liner and completed with 3-1/2 inch tubing with a bottomhole assembly (BHA) for JP.
After the workover job, the operator tried to revive the well with poor-boy gas lift technology by injecting gas into the casing annulus which passes through the ports of the jet pump's BHA into the tubing. Nevertheless, it failed to lift the well because of excessive hydrostatic head. Thus, a jet pump was brought in to revitalize its life. Based on software analysis, a high-volume jet pump was designed with 12A Nozzle/Throat combination and run in hole with a free-style JP. In the beginning, surface injection pressure and rate were kept low to kick off the well. When production became stable and oil cut increased, pumping parameters were increased gradually while monitoring daily production. These techniques helped to optimize production by tuning injection parameters at the surface. The well was revived to a producing rate of 1,240-1,290 BFPD with 45-50 BOPD at 98% water cut and injection rate and pressure of 3,350 BPD and 3,700 psi, respectively. The main benefit of the free-style JP was that it deployed and retrieved hydraulically without requiring slickline intervention.
In summary, jet pump was a proven well activation and lift solution for the candidate well. There are similar cases in the Middle East and North Africa (MENA) region and globally. In this case, JP technology was found to be an effective replacement for a poor-boy gas lifted well and helped the operator enhance production of the depleting brown oil field.
Nonlinear Analysis in p-Vector Spaces for Singe-Valued 1-Set Contractive Mappings
Authors: Yuan George X. 
Published: October 2022

Abstract

The goal of this paper is to develop some fundamental and important nonlinear analysis for single-valued mappings under the framework of p-vector spaces, in particular, for locally p-convex spaces for 0 < p ≤ 1. More precisely, based on the fixed point theorem of single-valued continuous condensing mapping in locally p-convex spaces as the starting point, we first establish best approximation results for (single-valued) continuous condensing mappings which are then used to develop new results for three classes of nonlinear mappings consisting of 1) condensing; 2) 1-set contractive; and 3) semiclosed 1-set contractive mappings in locally p-convex spaces. Next they are used to establish general principle for nonlinear alternative, Leray - Schauder alternative, fixed points for non-self mappings with different boundary conditions for nonlinear mappings from locally p-convex spaces, to nonexpansive mappings in uniformly convex Banach spaces, or locally convex spaces with Opial condition. The results given by this paper not only include the corresponding ones in the existing literature as special cases, but also expected to be useful tools for the development of new theory in nonlinear functional analysis and applications to the study of related nonlinear problems arising from practice under the general framework of p-vector spaces for 0 < p ≤ 1.
In addition, the work presented by this paper focuses on the development of nonlinear analysis for single-valued (instead of set-valued) mappings for locally p-convex spaces, essentially, is indeed the continuation of the associated work given recently by Yuan [134] therein, the attention is given to the study of nonlinear analysis for set-valued mappings in locally p-convex spaces for 0 < p ≤ 1.
Der Streit um die Kolbuszower Transaktion im Lichte der polemischen Abhandlungen „Uwagi w sprawie ordynacji ostrogskiej” von Tomasz Dłuski aus dem Jahr 1754 und „Prawda objaśniona” von Piotr Hadziewicz aus dem Jahr 1756

Ordynacja ostrogska powstała w 1609 roku. Obejmowała 23 miasta i ok. 400 wsi. Konflikt o ordynację ostrogską, związany z zapisami oraz wskutek śmierci wskazanych w statucie następców i zadłużenia doprowadził do jej rozwiązania na podstawie tzw. transakcji (ugody) kolbuszowskiej zawartej 1753 roku. W wydanym w 1754 roku traktacie Tomasz Dłuski dowodził, iż Janusza Aleksandra Sanguszkę nie obowiązywało prawo ordynackie, toteż mógł nimi rozporządzać według własnej woli i uznania. Trudnego zadania obrony ordynacji, prawdopodobnie za namową Jana Klemensa Branickiego podjął się Piotr Hadziewicz, prawnik i XVIII-wieczny publicysta.
Działalność prymasa Stefana Wyszyńskiego w perspektywie aparatu bezpieczeństwa
Authors: Dziurok Adam 
Published: October 2022

Funkcjonariusze aparatu bezpieczeństwa, którzy inwigilowali prymasa Stefana Wyszyńskiego przez cały okres jego urzędowania, kreślili uproszczoną wizję jego działalności, zredukowaną do aktywności na płaszczyźnie politycznej i społecznej. Podkreślali jego antykomunistyczne nastawienie, odnotowując przy tym systematycznie „wrogie” wystąpienia. Zwracano uwagę na centralizm i autokratyzm w zarządzaniu Kościołem, ale równocześnie dostrzegano w nim osobowość wielkiego formatu oraz człowieka oddanego bez reszty Kościołowi. Pod sam koniec życia prymasa aparat bezpieczeństwa kreślił już nieco inny jego obraz, wskazując na jego patriotyzm, zdolność do porozumienia i polityczny rozsądek.
W poszukiwaniu oficjum ainardowego
Authors: Grajewski Czesław 
Published: October 2022

Artykuł jest próbą dotarcia do pierwotnej struktury oficjum o św. Katarzynie z Aleksandrii. Wiadomo z przekazów historycznych, że takie oficjum skomponował mnich benedyktyński Ainard z klasztoru Św. Trójcy w Rouen po 1030 r. Niestety, nie mamy obecnie pewności, jak ono wyglądało. Autor analizuje liturgię brewiarzową w dniu św. Katarzyny zawartą w XIII-w. ordo z klasztoru Notre Dame de St. Pierre-sur-Dives, zakładając, że uformował ją pierwszy opat - właśnie Ainard, który został tam przeniesiony z Rouen z misją stworzenia ośrodka benedyktyńskiego. Zdaniem autora, w dotarciu do pierwotnego oficjum powinno pomóc kilka wyznaczników, m.in. tekst mówiący o uzdrawiającym olejku sączącym się z sarkofagu Świętej, który zadziałał leczniczo na chorobę dziąseł przełożonego klasztoru Św. Trójcy, Isemberta, a świadkiem tego wydarzenia był właśnie Ainard, jeden z pierwszych promotorów kultu św. Katarzyny.
