Background

Job satisfaction is one of the main factors creating and bringing about work motivation, productivity, and efficiency as well as decreasing job-hopping and job turnover. No previous studies have been conducted to assess job satisfaction for community pharmacists in Vietnam.

Objective

This research was conducted to develop and validate an instrument used to measure community pharmacists’ job satisfaction in the context of the COVID-19 pandemic in Vietnam.

Methods and results

A total of 351 pharmacists participated in this survey. Data were analyzed using R software version 4.2.0. The final instrument (VIJS) has 34 items divided into six factors which were determined via a parallel analysis (including physical working conditions, work nature, income and other benefits, management policies and managers, relationships with coworkers and customers, and learning and advancement opportunities). VIJS’s internal consistency was excellent (Cronbach’s alpha = 0.97, Omega total = 0.98, split-half reliability = 0.985, and composite reliability>0.8). Two-week test-retest reliability results (intraclass correlation coefficient for the overall instrument: 0.97, for six factors: 0.865–0.938) demonstrated the consistency of the VIJS when the same test was repeated on the same sample (62 pharmacists) at different points in time. The Confirmatory Factor Analysis was employed to assess the construct validity. The VIJS was a good fit to a six-factor model (Chisq/df = 2.352, Comparative Fit Index = 0.937, Tucker-Lewis Index = 0.929, Standardized Root Mean Square Residual = 0.042, and Root Mean Square Error of Approximation = 0.062). VIJS’s good convergent and discriminant validity was demonstrated via Average Variance Extrated>0.5 and the Heterotrait-Monotrait ratio of correlations<0.85.

Conclusions

The VIJS possesses good reliability and validity and can be used to measure community pharmacists’ job satisfaction.
Broadening Ontological and Epistemological Possibilities within Early Childhood Teacher Education for Sustainability
Authors:   University of Gothenburg, Sweden, Weldemariam Kassahun
Published: November 2022

The dominant sustainability ethos and discourse within early childhood education pursue a normative ontological and epistemological direction aimed at empowering children’s agency and thus, building certain predefined moral values, knowledge, and skills. Likewise, mainstream early childhood teacher education programmes strive to build early childhood pre-service teachers’ sustainability knowledge and skills, especially to enhance their capacity to be transformative agents and motivators for change to engage children with sustainability challenges. In this conceptual article, drawing on posthuman concepts, I highlight the limits of such orthodox assumptions in early childhood education for sustainability (ECEfS) teacher education and invite broader ontological and epistemic possibilities. I interrogate the human-centric assumptions that unintentionally perpetuate the deep-rooted binary thinking that separates humans from non-humans and other species. In doing so, I offer an expanded understanding of the underlying ontological and epistemic assumptions within teacher education for ECEfS. I conclude by indicating how posthuman theories serve as an impetus for epistemological and ontological multiplicities in early childhood teacher education for sustainability.

Published: November 2022

There is momentum towards implementing patient-derived xenograft models (PDX) in cancer research to reflect the histopathology, tumor behavior, and metastatic properties observed in the original tumor. These models are more predictive of clinical outcomes and are superior to cell lines for preclinical drug evaluation and therapeutic strategies. To study PDX cells preclinically, we used both bioluminescence imaging (BLI) to evaluate cell viability and magnetic particle imaging (MPI), an emerging imaging technology to allow for detection and quantification of iron nanoparticles. The goal of this study was to develop the first successful iron labeling method of breast cancer cells derived from patient brain metastases and validate this method with imaging during tumor development. Luciferase expressing human breast cancer PDX cells (F2-7) were successfully labeled after incubation with micron-sized iron oxide particles (MPIO; 25 μg Fe/ml). NOD/SCID/ILIIrg−/− (n = 5) mice received injections of 1x106 iron-labeled F2-7 cells into the fourth mammary fat pad (MFP). BLI was performed longitudinally to day 49 and MPI was performed up to day 28. In vivo BLI revealed that signal increased over time with tumor development. MPI revealed decreasing signal in the tumor over time. Here, we demonstrate the first application of MPI to monitor the growth of a PDX MFP tumor. To accomplish this, we also demonstrate the first successful labeling of PDX cells with iron oxide particles. Imaging of PDX cells provides a powerful system to better develop personalized therapies targeting breast cancer brain metastasis.
Analisis Pengaruh Perubahan Pembebanan Listrik Terhadap Konsumsi Spesifik Bahan Bakar Pembangkitan, Heat Rate dan Efisiensi Pada Unit 1 PLTU Kendari-3
Authors: Alber Ivan Darren , Kiono Berkah Fajar Tamtomo
Published: November 2022

Permbangkit Listrik Tenaga Uap (PLTU) Kendari-3 merupakan PLTU di Indonesia yang memanfaatkan energi batubara sebagai bahan bakar dengan kapasitas 2x50 MW. Beban yang dibangkitkan pada PLTU Kendari-3 tidak selalu konstan karena adanya fluktuasi beban pada jaringan listrik sesuai dengan permintaan konsumen (Ilham & Aksar, 2021). Konsumsi spesifik bahan bakar merupakan parameter yang penting untuk melihat efisiensi pembangkit listrik terhadap konsumsi dari bahan bakar yang digunakan untuk menghasikan energi listrik (Putra et al., 2021). Pada penelitian ini menganalisa pengaruh pembebanan listrik unit PLTU Kendari-3 terhadap nilai Specific Fuel Consumption (SFC), Net Plant Heat Rate (NPHR), Gross Plant Heat Rate (GPHR), dan efisiensi termal dengan menggunakan metode pendekatan analisis termodinamika dan metode input-output energi. Data yang dianalisis adalah data aktual saat operasi normal yang diambil dari Distributed Control System (DCS). Hasil dari penelitian ini menunjukan bahwa semakin besar beban unit PLTU Kendari-3 akan semakin semakin baik performa plantnya. Hal tersebut ditunjukan dengan kenaikan efisiensi 25,30 % pada beban 30 MW Net naik menjadi 29,89 % pada beban 40 MW Net, dan naik menjadi 30,40 % pada beban 50 MW Net. Selain itu naiknya performa plant juga ditunjukan dengan turunnya nilai Gross Plant Heat Rate (GPHR) dari 3.399,06 kkal/kWh pada beban 30 MW Net turun menjadi 2.876,62 kkal/kWh pada beban 40 MW Net, dan turun menjadi 2.828,46 kkal/kWh pada 50 MW Net.

Published: November 2022

Teknologi Pompa Air Tenaga Surya (PATS) saat ini dapat menjadi solusi penyediaan air untuk keperluan rumah tangga yang ramah lingkungan tertama di daerah terpencil yang belum tersedia listrik. Desain sistem yang tepat sangat tergantung pada kondisi geografis, penyinaran matahari yang tersedia, kebutuhan air domestik dan konfigurasi yang tepat dari sistem yang diusulkan. Oleh karena itu, tujuan dari studi ini adalah untuk membuat desain Pompa Air Tenaga Surya submersibel DC yang optimal yang mampu memasok sistem pompa surya untuk memenuhi kebutuhan air domestik dari desa terpencil yang terletak di kabupaten Manatuto, Timor Leste. Pendekatan rinci untuk desain PATS, disimulasikan berdasarkan data kebutuhan air penduduk dari hasil survei. Selain itu, studi desain PATS dilakukan dengan memperhatikan kondisi geografis. Berdasarkan kondisi tersebut dan letak pemukiman, maka desain sistem pemasokan air direncanakan menggunakan 2 metoda yaitu dengan sistem pemompaan dan sistem gravitasi. Dari hasil perhitungan jarak dan ketinggian antara sumber air dengan pemukiman penduduk yang membutuhkan pompa dengan total head statis yang besar tetapi debit kecil, maka jenis pompa yang cocok adalah pompa submersibel rotor heliks dengan arus DC. Hal ini karena listrik dari panel surya adalah listrik DC sehingga akan lebih efisien jika menggunakan pompa DC. Selain itu Pompa DC memiliki keunggulan lebih efisien karena memberikan output maksimum dengan panel surya yang lebih sedikit. Pompa surya AC membutuhkan lebih banyak panel surya karena listrik harus diubah menjadi AC untuk digunakan. Akibatnya, efisiensi sistem berkurang.

Published: November 2022

Pengeringan merupakan salah satu proses untuk memperpanjang masa simpan dari bahan yang dikeringkan. Jamur tiram merupakan suatu komoditas yang mempunyai masa simpan yang cukup singkat karena mempunyai kadar air yang cukup tinggi. Untuk memperpanjang masa simpan perlu dilakukan proses pengeringan. Banyak metode pengeringan yang dapat dilakukan untuk mengeringkan jamur tiram. Metode pengeringan dengan memanfaatkan sinar infrared dianggap sebagai metode yang cukup menjanjikan baik dari segi lama proses pengeringan, jumlah energi yang digunakan maupun biaya. Penelitian ini bertujuan untuk melakukan proses pengeringan jamur tiram dengan menggunakan lampu infra dengan menggunakan 3 level daya lampu. Adapun variasi level daya lampu (432 W, 504 W dan 624 W) dan berat bahan yang dikeringkan sebesar 500 gram. Parameter yang diamati meliputi penurunan kadar air terhadap waktu, perubahan temperatur dalam ruang pengering terhadap waktu dan specific energy consumption/SEC (kWh/kg). Hasil penelitian menunjukkan bahwa penurunan kadar air tercepat terjadi pada penggunaan level daya 624 W dimana kadar air tercapai sebesar 7,1% dalam waktu 130 menit. Level daya 624 W juga mencapai temperatur tertinggi sebesar 84°C dalam ruang pengering. Sedangkan specific energy consumption/SEC tertinggi yaitu 3,598 kWh/kg pada penggunaan level daya 432 W. Pengeringan jamur tiram menggunakan lampu infrared dengan daya 624 W lebih baik dibandingkan dengan level daya yang lainnya jika dilihat dari segi SEC paling rendah, kecepatan penurunan kadar air dan pencapaian temperatur dalam ruang pengering.

Authors: Nisa Khairun , Riyanto Riyanto
Published: November 2022

Program Lampu Tenaga Surya Hemat Energi (LTSHE) merupakan program elektrifikasi nasional kepada rumah tangga yang belum menggunakan listrik, khususnya yang berada di Papua mengingat sebagian besar desa yang belum menggunakan listrik berada di pulau ini. Dengan program ini, masyarakat mendapatkan penerangan dengan tingkat pencahayaan yang jauh lebih baik tanpa harus mengeluarkan biaya bahan bakar. Hal ini berdampak pada peningkatan peluang masyarakat untuk melakukan kegiatan di malam hari, salah satunya dengan melakukan kegiatan usaha skala rumah tangga. Penelitian ini bertujuan menganalisis dampak program LTSHE terhadap peningkatan banyaknya usaha skala rumah tangga di desa, yaitu usaha rumah tangga anyaman, toko kelontong dan warung makanan di desa terpencil di Papua. Dengan menggunakan data PODES 2014 dan 2020 serta menggunakan metode Difference in Difference, penelitian ini menemukan bahwa program LTSHE tidak berdampak terhadap peningkatan banyaknya usaha rumah tangga toko kelontong dan warung makanan. Bahkan dampaknya terhadap banyaknya usaha rumah tangga berbasis anyaman, malah negatif dan signifikan.
Low-loss, geometry-invariant optical waveguides with near-zero-index materials

Published: November 2022

Optical materials with nearly zero refractive indices have driven emerging applications ranging from geometry-invariant optical tunneling, nonlinear optics, optical cloaking to thermal emission manipulation. In conventional dielectric photonic circuits, light scattering and back reflection at the waveguide bends and crossings leads to significant optical loss. Here we propose to use near-zero-index materials as a cladding layer for low-loss optical waveguides, where optical modes are tightly confined within the dielectric core region. Compared to conventional waveguides, the near-zero-index waveguides are superior in maintaining a high mode-filling factor for small device sizes close to the diffraction limit and reducing the crosstalk in between at a sub-wavelength separation. In addition, we found that light propagation is robust to waveguide bends in a small radius (∼µm) and geometry variation in the cross section. Hollow waveguides with near-zero-index cladding layers further support low-loss light propagation because materials absorption is minimized from the air core. Our work offers critical insights into future designs of low-loss and miniaturized photonic devices.

Published: November 2022

Terahertz detectors based on two-dimensional Dirac materials offer a new approach for room-temperature terahertz detection with high response and low noise. However, these devices can hardly show high response over a broad frequency range, mainly due to the poor absorption caused by their ultrathin nature. Here we apply metallic gratings to enhance the excitation efficiency of graphene plasmons. When nonzero source-drain bias is applied, graphene plasmons can generate terahertz response orthogonal to the polarization of the incidence. The response is attributed to the orthogonal overdamped plasmon rectification effect, and graphene plasmons-enhanced photo-thermoelectric effect. By comparing the normalized on/off ratio, the metallic gratings are found to effectively enhance the coupling efficiency between graphene plasmons and THz incidence, and thus the absorption and responsivity. The results are beneficial for improving the response of room temperature THz detectors.

Published: November 2022

Nanodynamic therapy (NDT) based on reactive oxygen species (ROS) production has been envisioned as an effective cancer treatment. However, the efficacy is limited by the hypoxia, insufficient hydrogen peroxide conversion, and high glutathione (GSH) levels in the tumor microenvironment (TME). To solve these issues, we proposed and designed a biocompatible, oxygen resistant Cu-modified Ti3C2 nanocomposite (Ti3C2-Cu-PEG), which can efficiently deplete the endogenous GSH in tumor cells, smartly respond to NIR-II light irradiation with in-depth tissue penetration to achieve photothermally enhanced tumor photodynamic therapy (PDT) and catalytic therapy. Specifically, Ti3C2-Cu-PEG reacted with oxygen to produce singlet oxygen (1O2) under NIR-II irradiation, and catalyzed the highly expressed H2O2 in the tumor microenvironment to generate ·OH. In addition, Ti3C2-Cu-PEG significantly decreased intracellular GSH, reduced the chances of reaction between ROS and GSH, and thus promoting ROS effect. Moreover, the intrinsically high photothermal conversion efficiency of Ti3C2-Cu-PEG further promotes the NDT process. In vitro and in vivo experiments, the Ti3C2-Cu-PEG nanosystem showed excellent antitumor effect in 4T1 tumor-bearing mice by amplifying oxidative stress under NIR-II stimulation. This work highlights an easily synergistic nanosystem with remodeling TME and combined photothermal therapy to enhance the therapeutic effect of NDT in tumor therapy.
Analytical analysis for non-homogeneous two-layer functionally graded material
Authors: Dastjerdi Farhad Belalpour , Jabbari Mohsen
Published: November 2022

In this study, the nonlinear analytical analysis of a two-layer geometry made of functionally graded materials (FGMs) is examined. FGMs can be used in various engineering applications, such as building materials in civil engineering, due to the advantages of smoothly varying properties. The equations of stresses and displacements in the radial and circumferential directions (r, θ ) have been found by extracting the governing equations and defining them in the form of power-exponential functions. In the present paper, modulus of elasticity and heat conductivity coefficient (except for Poisson’s coefficient) are assumed to be expressed by power-exponential functions in radial and circumferential coordinates. The temperature distribution is also considered as a function of radius (r) and angle (θ). The analysis is implemented based on the theory of small elastic deformations and with the assumption of a very large length in plane strain mode. To analyze the governing equations, first, the heat transfer equations are obtained, and then the Navier’s equations are derived by combining the stress–strain, strain–displacement, and stress equilibrium equations. Then, the displacement equations and stress equations are obtained by solving the Navier’s equations. A direct method is presented to solve these equations analytically.
The significance of participation in transcendence in Luther and Przywara
Authors: Alfsvåg Knut
Published: November 2022

Plato and Aristotle understood phenomena to be knowable to the extent that they participate in the reality of the unchangeable, and this attitude was appropriated by the church fathers as a way of exploring the world’s dependence on its Creator. Luther’s insistence on the world’s sinfulness and on salvation as one-sidedly dependent on divine agency has been criticized as a rejection of this understanding of the inherent goodness of the world, thus paving the way for the secularized world view of modernity. Among these critics is Erich Przywara in his works up to and including his book Analogia Entis from 1932. However, in 1952 Przywara published an article where he found Luther’s theology of exchange to be a close parallel to his own doctrine of analogia entis, the implication being that Luther is closer to a Catholic understanding of the world’s relationship with God than mainstream post-Enlightenment Protestantism, and this article is an attempt to substantiate that claim.
Remoto homine
Authors: Klinge Hendrik
Published: November 2022

With the current discussion about posthumanism, the traditional concept of man has become questionable. This also poses severe challenges for theology. In addition to theological anthropology, Christology is particularly affected by this. When it is no longer possible to answer unequivocally what it means to be human, it becomes even more controversial than before how the figure of the Deus-homo should be interpreted. The paper at hand presents a thought experiment in order to check whether it is possible to develop a Christology if one adopts central ideas of recent posthumanist scholarship. Taking Anselm’s famous remoto Christo argument as a model, the thought experiment avoids referring to the concept of man. After three major types of Christology haven been tested, the experiment yields the result that only a very abstract Christology is possible without resorting to explicitly anthropological assumptions. Rather, Christology can be seen as a reason why Christian theologians should reject posthumanism altogether. God has a human face, not a posthuman one.

Published: November 2022

Internet of medical things (IoMT) communication has become an increasingly important component of 5G wireless communication networks in healthcare as a result of the rapid proliferation of IoMT devices. Under current network architecture, widespread access to IoMT devices causes system overload and low energy efficiency. 5G-based IoMT systems aim to protect healthcare infrastructure and medical device functionality for longer. Therefore, using energy-efficient communication protocols is essential for enhancing QoS in IoMT systems. Several methods have been developed recently to improve IoMT QoS; however, clustering is more popular because it provides energy efficiency for medical applications. The primary drawback of the existing clustering technique is that their communication model does not take into account the chance of packet loss, which results in unreliable communication and drains the energy of medical nodes. In this study, we concentrated on designing a clustering model named Whale optimized weighted fuzzy-based cluster head selection algorithm to facilitate successful communication for IoMT-based systems. The experimental study shows that the proposed strategy performs better in terms of QoS than compared approaches. Inferring from this, the proposed method not only reduces energy consumption levels of 5G-based IoMT systems but also uniformly distributes cluster-head over a network to improve QoS.
Irish cattle farmers’ experiences and perceptions of negative framing of farm animal welfare in the media
Authors: Duley A. , Connor M. , Vigors B.
Published: November 2022

Increased urbanisation in recent decades has created a knowledge gap between farming and the Irish public. Mainstream media has begun filling this gap through reports on farm animal welfare (FAW) incidents that sometimes frame farming in a negative way. This negative framing can influence how farmers perceive the information communicated in these media stories and colour their experiences. Furthermore, perceived societal pressures may contribute to farmers feeling overwhelmed or negatively impact their mental health. In the context of FAW, the latter is particularly relevant as poor farmer mental health has been associated with poorer animal welfare. However, little is known about how the negative framing of FAW stories influence farmers’ perceptions and experiences. The aim of this study was to explore how negatively framed media stories about FAW incidents affect cattle farmers’ perceptions of animal welfare. Face-to-face interviews were conducted with seven Irish beef and dairy farmers using vignettes displaying negatively framed FAW incidents presented in the media. Five themes were identified: (1) job satisfaction and motivation, (2) impact on the human–animal relationship, (3) the importance of community, (4) negative portrayal of farmers and (5) need for FAW education. Findings suggest that negative framing of FAW in the media, as well as rural restructuring in Ireland, may negatively affect farmers’ motivation which could have indirect implications for the welfare of their animals.

In many digital image-processingapplications, which are implementedin field programmable gate arrays,the currently processed image's frames are stored in external dynamic memory.The performance of such an application dependson the dynamic memoryspeed and the necessaryrequests quantity during algorithm’sruntime. This performance is being optimized through field programmable gate arrays -implemented buffer memory usage.But there is no common method for the formal buffer memory synthesis with preset throughput, input and output data sequenceorderand minimizedhardwarecosts.In this article,the featuresof image input and processing based on Field Programmable Gate Arrayareconsidered.The methods of building buffer circuits in field programmable gate arrays, due to which the intensity of data exchanges with external memory is reduced, are analyzed. Themethod of synthesizing pipeline circuits with specified performance characteristics and the data sequence order is given, which is based on the mapping of the spatial synchronous data flows into the structure implemented in the field programmable gate arrays.A method of designing buffer schemes is proposed, which is based on the mapping of spatial synchronous data flows into local memory in the form of chains of pipeline registers.The method helpsto organize the data flow of at the input of built-in pipeline units of image processing, in which the data follow in a given order, andto minimize the amount of buffer memory.The method ensures the use of dynamically adjustable register delays built into the field programmable gate arrays, which increases the efficiency of buffering.Thismethod was tested during the development of an intelligent video camera. The embedded hardware implements a video image compression algorithm with a wide dynamic range according to the Retinexalgorithm. The same time it selects characteristic points in the image for the further pattern recognition.At the same time, multiple decimation of the frame is performed. Due to themultirate buffering of the image in the field programmable gate arrays,it was possible to avoid using of external dynamic memory.

У статті проаналізовано розвиток педагогічної думки в Румунії щодо вагомості та необхідності фізичного виховання школярів кінця ХІХ – першої третини ХХ століть. Так, визначено, що фізичне виховання, на думку низки фахівців, принесло в освіту, зокрема, в інтелектуальне виховання лише недоліки. Авторкою наведені «за» і «проти» такого негативного ставлення; доведено, що і прихильники, і супротивники фізичного виховання і спорту визнавали їх потребу і роль у вихованні дітей та молоді країни, підтримували політику Румунії щодо обов’язковості їх розвитку. Зроблено висновок, що тема необхідності і вагомості такої діяльності була досить актуальною як серед педагогів і практиків-тренерів у спортивних клубах, так і журналістів та священнослужителів, громадських діячів тощо. Наведено приклади існування різноманітних думок і теорій, у яких одні доводили, що вплив фізичної активності на організм молодої людини тільки позитивний, інші вважали спорт згубною звичкою; дехто називав заняття фізичними вправами обов’язковими для дівчат, інші окремі ж були категорично проти. У праці засвідчено, що тематика занять фізичними вправами, розвиток спортивної діяльності серед представників молодого покоління залишались актуальними.

Published: November 2022

To gain insight into the mechanical properties of crushed sugarcane tail leaves during stress relaxation, a self-made compression equipment was used in this study. The variation law of different factors on the stress relaxation process of crushed cane tail was explored and a stress relaxation model was established. The three-element and five-element generalized Maxwell models were selected to fit the regression analysis of the stress relaxation curve of the crushed cane tail. The comparison showed that the determination coefficient R2 of the five-element stress relaxation model was higher, and a three-factor and three-level response surface test was designed. Following the quadratic regression polynomial of the stress rapid decay time and the equilibrium elastic modulus, the final optimization results obtained are as follows: The moisture content was 60.8%, the crushing particle size was 45 mm, the feeding amount was 150 g, and the stress rapid decay time was 14.0 s. The equilibrium elastic modulus was 129 kPa.

Biomass-derived 5-hydroxymethylfurfural (5-HMF) is a potential raw material for the production of a wide range of valuable chemicals and biofuels. Industrial production of 5-HMF from hexoses on solid catalysts is promising nowadays. Acid zeolites have great potential in application as catalysts for the dehydration of sugars. The purpose of this work was to obtain granular zeolite catalysts with optimal acidity and evaluate their effectiveness depending on the nature of the binder used. A zeolite catalyst without binder and samples with 10 wt % of kaolin/alumina were prepared. Their porous characteristics and acidity were studied by means of nitrogen low temperature adsorption/desorption, ammonia thermo-programmed desorption, and pyridine adsorption with IR control. The activity and selectivity of the catalysts for 5-HMF synthesis from glucose in the dimethyl sulfoxide medium at 160 ◦C were studied. The high efficiency of granular samples in glucose transformation into 5-HMF is confirmed. They are not only not inferior to, but even superior to, powdered samples. The component sources of Brønsted and Lewis acidity of the ammonium form of zeolite, which demonstrates acceptable activity (selectivity for 5-HMF is 34 %) despite the small number of Lewis centers, are considered in detail. The highest efficiency is demonstrated by the sample with aluminum oxide, which not only does not significantly deteriorate the microporous characteristics but also improves the mesoporosity of the catalyst. The selectivity towards 5-HMF on it reaches 44%. However, the developed mesoporosity of the sample with aluminum oxide is not critical to its activity. The main influence on the effectiveness of the catalyst in the synthesis of 5-HMF is played by the presence of acid centers of medium strength.

The gas-phase oxidation of ethylene glycol and methanol mixture into methyl glycolate С2H6O2+CH3OH+O2 = C3H6O3+2H2О over synthesized copper-containing catalysts was studied. Methyl glycolate can be considered as raw material for obtaining biodegradable polyglycolide. The CuO-containing samples were synthesized by impregnation of granular oxide-supports (γ-Al2O3, SiO2 and MgO-ZrO2) with the calculated amount of aqueous solution of Cu(NO3)2·3H2O followed by heat treatment at 400 °C. In such way the supported CuO-MexOy /Al2O3 (Me = Mg, Ti, Cr, Co, Zn, Zr, Ag) samples have been prepared. Catalytic experiments were performed in a stainless-steel flow reactor with a fixed bed of catalyst at 200-270 °C and atmospheric pressure. Oxygen of air was used as an oxidant. The reaction products were analyzed using 13C NMR spectroscopy and gas chromatography. It was found that СuO/Al2O3 catalyst provides ~ 100% ethylene glycol conversion with 56% selectivity towards methyl glycolate at 220 °С. The main by-products are methoxymethanol, 1,1-dimethoxymethane, methyl methoxyacetate, and methyl formate. Use of silica as catalyst support leads to a significant decrease of the ethylene glycol conversion to 57 % for CuO/SiO2, but methyl glycolate selectivity does not change significantly. Promotion of СuO/Al2O3 with MgO increases methyl glycolate yield to 64%. According to the scheme of ethylene glycol sequential oxidation the increase in selectivity for methyl glycolate over CuO-MgO/Al2O3 catalyst is caused by the basic sites that promote intramolecular Cannizzaro rearrangement of the intermediate reaction product – glyoxal hemiacetal to methyl glycolate. It’s found that mixed CuO-CrO3 oxide supported by γ-Al2O3 provides 80 % methyl glycolate selectivity with 95-100% ethylene glycol conversion at 200-210 °C.

In this article the problems associated with the corrosion processes of equipment in oil and gas production are analyzed. The basic anticorrosive methods and means used in modern conditions are considered. Taking into account the mechanism and conditions of corrosion processes in the extraction and transportation of oil-containing products and gas condensate, the chemical method of protection of the equipment was chosen for research. Both known inhibitors based on phosphonic acids and synthesized substances based on sulfonates, imidazolines, and diamines were used as chemicals in the research. As a result of the research, the effectiveness of protection of metals from corrosion depending on the composition of highly mineralized medium, metal type, inhibitor type, and its concentration was evaluated and the effectiveness of the developed scale stabilizer (sodium dimethylsulfonate phosphinate) was evalu- ated in comparison with known reagents. It is shown that the effectiveness of protection of metals from corrosion in aqueous-petroleum mixtures with alkylimidazoline inhibitors (derivatives of 4,5-dihydro-1,3-diazole or 4,5-dihydroimidazole) and inhibitors developed on the basis of sunflower oil and diethylenetriamine (AC-1), ethylenedi-amine (AC-2) reaches 90% in doses of 5 - 50 mg/dm3. In addition, corrosion processes are often accompanied by processes of deposition of hardness salts on the surface of the equipment, which leads to a significant complication in the operation of the equipment. Therefore, studies of the anti-scale properties of these reagents under harsh conditions were performed. Real concomitant gas production waters were used as the medium. It was found that sodium di-methylsulfonate phosphinate is a very effective stabilizer of scale formation and is not inferior in effectiveness to known antiscalants. The proposed reagents can be used to stabilize water-oil mixtures and associated formation waters formed during the production and transportation of oil and gas.

The Indonesian government is trying to reduce the poverty rate, among others, by encouraging investment sourced from within the country and abroad and increasing the number of micro, small and medium-sized businesses. However, until the end of 2020, the category of poor people in Indonesia is still relatively high, about ten per cent of the total population of Indonesia. This research problem encouraged the authors to examine the role Domestic Investment (DI), Foreign Investment (FI) and Micro, Small, and Medium Enterprises (MSMEs) to reduce poverty in Indonesia. This is also because there has been no previous Indonesian research involving the four variables with data from 2010 to 2020. This study used quantitative methods to determine the impact of DI, FI and MSMEs on the magnitude of poverty. Data combining time series and cross-section data is analyzed using the least square panel method. The results of the study showed that poverty would decrease when there is an increase in domestic investment, an increase in foreign investment, and an increase in the number of micro, small and medium-sized enterprises in Indonesia.

Vibrio merupakan bakteri yang menyebabkan banyak penyakit pada budidaya udang. Monitoring kelimpahan Vibrio penting dilakukan sebagai tindakan pencegahan penyakit pada larva udang vannamei.. Perbedaan sistem manajemen kualitas air pada setiap kolam budidaya dapat berpengaruh kepada dinamika populasi Vibrio. Studi mengenai korelasi populasi Vibrio dengan faktor lingkungan pada tambak pemeliharaan larva udang vannamei telah dilakukan pada bulan Maret – Juni tahun 2018 di Situbondo, Jawa Timur Indonesia. Populasi Vibrio naik secara gradual seiring dengan pertumbuhan larva. Pada stadia larva PL6 mengalami penurunan saat pemberian probiotik kemudian naik kembali pada PL7 sampai dengan PL12. Total Vibrio memiliki korelasi positif yang signifikan (Spearman Correlation Test, P<0,05) dengan parameter kualitas air; NH4 (r=0,852), NH3 (r=0,679), Salinitas (r=0,565), dan NO2 (r= 0,453). Namun memiliki korelasi negative yang signifikan dengan pH (r=-0,478, P<0,05) dan koreasi tidak signifikan dengan Suhu (r=-0,02, P>0,05). Dari 20 sampel air terhitung jumlah rata-rata Vibrio pada media pembenihan adalah  0,15 CFU/mL, masih dalam rentang normal dalam kegiatan pembenihan udang vanname.

A Comparison of the Serial Order Strategy and the Associative Cue Strategy for Decision Making in Wayfinding Tasks
Authors: Bock Otmar , Borisova Steliana
Published: November 2022

It has been proposed that in wayfinding, humans can use multiple strategies to decide which direction to take at intersections. One of them is the serial order strategy, where travelers memorize the order in which those directions should be taken. Another is the associative cue strategy, where travelers memorize associations between conspicuous objects along the way, and the directions to take. We designed tasks in which participants had to base their decisions on the serial order strategy (task S), on the associative cue strategy (task A), or were free to use either of those strategies (task SA). We found that performance errors decreased with practice in all three tasks but were higher in A than in S and SA. We conclude that in our study, the serial order strategy was more efficient than the paired associate strategy. We further conclude that this outcome is likely to depend on task demand, which calls for additional research that varies not only the available strategies, but also the task demand.
Paradiplomacia financeira e mudanças institucionais: o caso do Rio Grande do Sul (1987 - 2014)
Authors: Rodriguez Júlio C. , Junges Matheus da Silva
Published: November 2022

Resumo: Neste artigo exploramos a operacionalização da paradiplomacia financeira no estado do Rio Grande do Sul. Analisamos a trajetória institucional em três períodos (1987-1990, 2007-2010 e 2011-2014), para compreender quais instituições foram criadas e/ou modificadas, como ocorreu a atuação destas instituições estatais na captação de recursos financeiros no exterior e como se deu a efetivação da paradiplomacia financeira no estado, a partir do volume de recurso captado por meio de operações financeiras internacionais. Nossa hipótese principal é que a existência de instituições responsáveis pela paradiplomacia financeira foram relevantes para a captação de recursos pelo estado do Rio Grande do Sul. Realizamos para isto uma abordagem qualitativa, com suporte de estudo de caso, com rastreamento de processos com suporte documental, de dados financeiros e de entrevistas semiestruturadas. Encontramos que primeiro há criação de dois órgãos responsáveis pela paradiplomacia financeira, SEAI e DCP, depois ocorre um drift (ou derivação) institucional que as modifica em SEDAI e DECAP e, por fim, um displacement (ou deslocação) institucional com a divisão da SEDAI em três novas instituições a ACRI, a SDPI e a SESAMPE e uma conversion (ou conversão) do DECAP, para sua continuidade. Também encontramos, a partir das entrevistas, que a efetividade da paradiplomacia financeira no estado foi afetada diretamente por três fatores inter-relacionados: (i) a influência do personalismo; (ii) a limitação da capacidade de endividamento e pagamento das operações financeiras; e (iii) a restrição de instituições financeiras cofinanciadoras de projetos no Rio Grande do Sul.
