Performative and economic analysis on local duck farming in Central Java - Indonesia
Authors: Ismoyowati I. , Pratama B. C. , Innayah M. N. 
Published: October 2020

Central Java is the region that produces the second largest duck egg production in Indonesia or reaches 13.55% of the total national duck egg production. Therefore, duck farming in Central Java requires an economic evaluation to identify the success of the business. The economic analysis in the duck farm industry will update the latest statistics on production costs, outputs and profitability. This study aims to assess the analysis of laying duck business, which includes: marginal production costs, total net income and input-output ratio of duck egg production in various regions in Central Java, Indonesia. The study was conducted using a survey method using multi-stage sampling involving 120 duck farmers from the regency of Tegal, Brebes, and Pemalang. Each district was taken 40 farms as respondents by purposive random sampling with criteria for the number of breeders who had a minimum duck population of 100 ducks and a production period of 8-12 months. The analytical tools used include descriptive statistics and farm budgetary analysis. This study showed that duck breeders incur large costs to obtain production inputs, especially from feed aspects. Although three regencies reported profit based on the estimated input-output ratios, it is only a marginal profit that amounted to1: 1.382, 1:1.658, and 1:1.433 in Tegal, Brebes, and Pemalang, respectively. The conclusion of the study is the performance of duck farms in Central Java are still profitable even in the smallholder duck farm industry, with the highest profits obtained by farmers in Brebes Regency.
In-group, out-group effects in distributional preferences: the case of gender
Authors: Jaber-Lopez Tarek , Baier Alexandra , Davis Brent J. 
Published: October 2020

Abstract
We examine gender differences when eliciting distributional preferences as conducted by the Equality Equivalence Test, which has the ability to classify subjects into preferences types. Preferences are elicited when individuals interact with an individual of the same gender and with an individual of the opposite gender. We find elicited preferences are robust across both in-group (same gender) and out-group (opposite gender) interactions. When analyzing the intensity of benevolence (or malevolence) we find that overall women exhibit more malevolence than men, but there is no gender difference for benevolence. Furthermore, women exhibit a higher level of in-group favoritism than men.
From transistor level to cyber physical/hybrid systems: Formal verification using automatic compositional abstraction
Authors: Tarraf Ahmad , Hedrich Lars 
Published: October 2020

Abstract
In this paper we present a methodology to automatically generate an accurate behavioral model from an analog circuit description. The current machine learning method is limited to circuits with up to 80 transistors, limiting our approach to small and mid size circuit blocks due to a state explosion problem. However, if complex building blocks such as IOT systems should be modeled, the current approach needs to recoup with feasible simulation and modeling time. To come up with a solution for this problem, we extend the current method by a compositional approach. The approach is illustrated upon an example from the area of autonomous driving. Our method decomposes this large example into smaller building blocks and models each of them automatically. All models are combined into a compositional hybrid automaton of the whole complex system.
Compared to the original state space, the building blocks operate on smaller and reduced state spaces and hence drastically reduce the complexity. Using a back-transformation on the compositional automaton, all values from the original state space can be reconstructed. Moreover, we perform a formal verification on the generated compositional automaton. Results from a meaningful example are presented and discussed.
The Mystery of Reciprocal Demand for Regional Trade Partnership: Indian Experience in RCEP Regional Value Chains
Authors: Chakraborty Debashis , Chaisse Julien 
Published: October 2020

Abstract
The decision of a country to join regional trade agreements (RTAs) is guided by its expected welfare gains, though potentials of both trade creation and trade diversion cannot be ruled out through such arrangements. The slow progress of the World Trade Organization negotiations has created a demand for mega-regional trade agreements in the last decade, but the recent US and Indian pullout from Trans-Pacific Partnership (TPP) and Regional Comprehensive Economic Partnership (RCEP), respectively, raised a question on their attraction. One of the major underlying objectives of RTAs is to deepen intra-bloc participation in regional value chains (RVCs) and International Production Networks (IPNs), through adoption of reformed rules of origin (ROO) provisions and mutual recognition agreements (MRA) for standard harmonization. This article, through an analysis of the RVC–IPN participation of the RCEP countries, attempts to understand to what extent the Indian pullout from RCEP can be linked to its unfulfilled expectations. The observations indicate that, relatively modest participation in the RVCs, declining domestic value added content of exports and the associated adverse trade balance scenario have critically shaped the Indian standpoint. The evolving Indian orientation towards trade remedy mechanism can be viewed in this backdrop. The analysis concludes that in the post-coronavirus disease 2019 (COVID-19) period, the Indian decision to consolidate domestic manufacturing sector needs to acknowledge the reality rather than being guided by the rhetoric.

AbstractSensor technology has become increasingly crucial in medical research and clinical diagnostics to directly detect small numbers of low-molecular-weight biomolecules relevant for lethal diseases. In recent years, various technologies have been developed, a number of them becoming core label-free technologies for detection of cancer biomarkers and viruses. However, to radically improve early disease diagnostics, tracking of disease progression and evaluation of treatments, today’s biosensing techniques still require a radical innovation to deliver high sensitivity, specificity, diffusion-limited transport, and accuracy for both nucleic acids and proteins. In this review, we discuss both scientific and technological aspects of hyperbolic dispersion metasurfaces for molecular biosensing. Optical metasurfaces have offered the tantalizing opportunity to engineer wavefronts while its intrinsic nanoscale patterns promote tremendous molecular interactions and selective binding. Hyperbolic dispersion metasurfaces support high-kmodes that proved to be extremely sensitive to minute concentrations of ultralow-molecular-weight proteins and nucleic acids.
Effective Connectivity Reveals an Interconnected Inferotemporal Network for Three-Dimensional Structure Processing
Authors: Premereur Elsie , Janssen Peter 
Published: October 2020

Disparity-defined 3D shape is processed in both the ventral and the dorsal visual stream. The network of cortical areas that is activated during the processing of disparity-defined 3D shape includes, in addition to parietal and premotor areas, three clearly distinct regions in inferotemporal cortex (ITC). To investigate the connectivity of the latter regions, we combined electrical stimulation with fMRI in male macaque monkeys. Electrical stimulation of each of the 3D-structure nodes in ITC mainly elicited increased fMRI activations in the other 3D-structure nodes and more variably in other parts of ventral visual cortex. Importantly, no increased activation was found in parietal areas, nor in PFC, whereas microstimulation in posterior parietal cortex did activate the ITC. Our results indicate that 3D-structure nodes in ITC form a strongly interconnected network, receiving input from parietal areas implicated in 3D-structure processing.SIGNIFICANCE STATEMENTPrevious studies combining electrical microstimulation with functional imaging showed an interconnected set of regions in the ventral stream processing faces or bodies, but is has been unclear whether the same is true for other visual categories. Here the authors show that there is a connected system of stereo-selective regions in inferotemporal cortex, receiving input from parietal areas in the dorsal stream.

Summary

89Sr, a pure beta emitter with half life of 50.53 d is used as its chloride solution for palliative care of bone metastases. This paper describes the feasibility studies that have been conducted at FBTR, IGCAR for production of this radionuclide using the 89Y(n, p)89Sr reaction. Yttria pellets were irradiated in a special subassembly at the core centre for a total of 73 d in two steps of 35 d and 38 d with a time gap of 38 d. The irradiated yttria target was dissolved in nitric acid and the bulk Y was separated by solvent extraction using the TBP-HNO3 complex. The 89Sr fraction was purified using the cation exchange resin DOWEX 50W×8 (100-200 mesh size) from the other radioactive impurities seen. The eluted 89Sr fraction was assayed using a GM counting system. The 89Sr activity produced in 1 g of yttria pellet was found to be 19 mCi.

AbstractTh accurate rapid, simple and selective reversed phase high performance liquid chromatography (RP-HPLC) has been established and validated for the determination of captopril (CAP). Chromatographic separation was accomplished using prepacked ODSI C18 column (250 mm × 4.6 mm with 5 μm particle size) in isocratic mode, with mobile phase consisting of water: acetonitrile (60:40 v/v), pH adjusted to 2.5 by using 85% orthophosphoric acid at a flow rate of 1 mL/min and UV detection was performed at 203 nm. RP-HPLC method used for the analysis of CAP in mobile phase and rabbit plasma was established and validated as per ICH-guidelines. It was carried out on a well-defined chromatographic peak of CAP was established with a retention time of 4.9 min and tailing factor of 1.871. The liquid–liquid extraction method was used for extraction of CAP from the plasma. Excellent linearity (R2 = 0.999) was shown over range 3.125–100 µg/mL with mean percentage recoveries ranges from 97 to 100.6%. Parameters of precision and accuracy of the developed method meet the established criteria. Intra and inter-day precision (% relative standard deviation) study was also performed which was less than 2% which indicate good reproducibility of the method. The limit of detection (LOD) and quantification for the CAP in plasma were 3.10 and 9.13 ng/mL respectively. The method was suitably validated and successfully applied to the determination of CAP in rabbit plasma samples.

idején nyújtandó szolgáltatásokról ajánlásokat (megfelelő tájékoztatás, a
gyógyszerellátottság biztosítása, a rendelési idők kiszélesítése, távkonzultáció
bevezetése) fogalmazott meg. Célkitűzés: Az ajánlások
háziorvosi ellátórendszerbeli érvényesülésének, a betegellátás (napi
betegforgalom, a légúti betegek ellátása, javaslatos készítmények felírása,
keresőképtelen állományba vétel) változásainak felmérése.
Módszer: 2020. április 26. és május 3. között háziorvosok
körében online, anonim, 26 tételes kérdőíves adatgyűjtés történt a medukator.eu
weboldalon (a praxisok alapjellemzői; a járvánnyal kapcsolatos szabályok
ismerete; információs csatornák/hatékonyságuk; a betegforgalom és a rendelési
idő változása; távkonzultáció; a légúti betegek ellátása).
Eredmények: A kérdőívet 787 (287 férfi és 500 nő) háziorvos
töltötte ki. A háziorvosok 96,6%-a a járási hivataltól értesül a járvánnyal
kapcsolatos feladatairól, 44,6% szerint elegendő a tájékoztatás. A betegek
lakóhelyi tájékoztatásával a háziorvosok 20,8%-a teljes mértékben elégedett,
szemben a központi tájékoztatással (15,4%). Minden háziorvos szerint –
életkoruktól függetlenül – járványban bárkinek rendelhető gyógyszer

8,5, a 15 000–50 000 lakosú városokban 9,4, míg az 5000–15 000 fős településeken
15. Az otthoni átlagos heti látogatások szignifikáns mértékben csökkentek a
40–65 év közötti (a járvány előtt: 8,3; a járvány idején: 1,5), illetve a 65
évesnél idősebb (a járvány előtt: 7,52; a járvány idején: 1,1) háziorvosoknál. A
praxisok 87%-a felkészült a távkonzultációra, ennek megtartását támogatja a 40
év alattiak 53,8%-a, a 40–65 év közöttiek 52,5%-a, a 65 év felettiek 43%-a.
Következtetések: A járványhelyzet felhívta a figyelmet az
egyértelmű, egycsatornás információk hiánya okozta problémákra a háziorvosi
rendszerben Magyarországon. A rendelői és az otthoni betegellátások számának
csökkenése mellett bebizonyosodott, hogy a távkonzultáció rendszerszinten is
működhet, jelentősen bővített esetkörrel a jövőben is kívánatos a napi
gyakorlatban. Orv Hetil. 2020; 161(40): 1699–1705.
STUDENT’S ATTITUDES TOWARDS CHILDREN WITH DISABILITY
Authors: Krausz Anita 
Published: October 2020

Several studies have shown that integrated education has advantages in students’ social development and accepted attitude development (Meyer, Park, Grenot-Scheyer, Schwartz & Harry, 1998). The studies about the integrated education had been traced for several decades, our research is based on the CATCH (Chedoke-McMaster Attitudes Towards Children with Handicaps Scale) questionnaire (Rosenbaum, 1985) which instrument had been used in several international studies as well (Tirosh, 1997; Vignes, 2008; Godeau 2010; Bosseart, 2011; De Laat, 2013, Schwab, 2017). Our major aim is to map the adolescent youth, their attitudes towards children with special treatment. The questionnaire was based on the three-component model of attitudes proposed by Triandis (1971). This 36-item, the self-administered scale was primarily paper-based, but our adaptation is placed on the online form. The participants of the study were 7th-grade students (N=99) The overall reliability of the test was satisfactory (Cronbach-α= 0,856). In the content analysis, we found two items that were significantly negative and four items which were not significant, those leaving the KMO= 0,809 (KMO>6), therefore suitable for factor analysis. The results show that, however in our sample, these three-component factors aren’t so clear, the test is reliable. There are some subtests that call for a revision, and we will need further researches to develop our assessment tool to make it more reliable and valid.

Published: October 2020

Abstract
Implementation of Managed Pressures Drilling (MPD) techniques provide substantial advantages for addressing difficulties in challenging wells. These benefits include not only the early influx and loss detection, but also Dynamic Influx Management. MPD provides the ability to circulate out an influx at drilling circulation rates while remaining within the primary well control barrier. Dynamic influx management is a trending topic within the industry, with its importance capturing the attention of planning and operational teams, regulatory bodies, and industry interest groups tasked with the development of recommended practices. Evolving from conventional kick tolerance to MPD kick tolerance has enabled dynamic influx management milestones, such as the adoption of the MPD operational matrix. More recently, the novel approach of the Influx Management Envelope (IME) has been increasingly adopted by the industry. This paper presents the state-of-the-art engineering analysis and operational considerations for dynamic influx management during MPD operations. As part of an integrated approach, this work considers three main aspects; 1) MPD kick tolerance, including concepts and its variables of interest, 2) IME generation and parameter sensitivity analysis, 3) generation of an MPD operational matrix. In addition, the advantages and disadvantages of various approaches to determining the limits of dynamic influx circulation are discussed.
Significant Surge and Swab Offshore Brazil Induced by Rig Heave During Drill Pipe Connections

Published: October 2020

Summary
This paper describes measured and simulated downhole pressure variations ("surge and swab") during drill pipe connections when drilling an ultra-deepwater well offshore Brazil on the Carcará field. Floating rig motion caused by waves and swell ("rig heave") induces surge and swab when the drill string is suspended in slips to make up or break a drill pipe connection and topside heave compensation is temporarily deactivated. This is a known issue in regions with harsh weather such as the North Sea, where pressure oscillations of up to 20 bar have been reported during connections. Recorded downhole drilling data from the Carcará field reveals significant pressure oscillations downhole (in the same order of magnitude as in the North Sea) each time the drill string was suspended in slips to make a connection in the sub-salt 8 ½" section of the well. Mud losses were experienced around the same well depth and they might have been caused by surge and swab.
Measured surge and swab pressure variations have been reproduced in an advanced proprietary surge and swab simulator that considers rig heave, drill pipe elasticity, well friction, non-Newtonian drilling mud, well trajectory and geometry. Moreover, findings in this paper suggest that surge and swab was in fact significantly higher than recorded by the MWD (Measurement While Drilling) tool. The true magnitude of surge and swab is not captured in the recorded MWD data due to low sampling frequency of the downhole pressure recording (one measurement every six seconds, a standard downhole pressure sampling rate used on many operations today).
This work shows that surge and swab during drill pipe connections on floaters may challenge the available pressure window for some wells even in regions with calm weather such as Brazil. Managed Pressure Drilling (MPD) is a technique that improves control of the downhole pressure. It is, however, not possible to compensate fast downhole pressure transients, such as heave-induced surge and swab, using MPD choke topside. This is due to the long distance between the choke and the bit, which translates into a time delay in the same order of magnitude as typical wave and heave periods. A downhole choke combined with continuous circulation is one of potential solutions.
Surge and swab during drill pipe connections can result in a loss or an influx and should be considered in the well planning phase when mud weight, section lengths, etc. are selected.
