Investigation on the Emission Characteristics with a Wet-Type Exhaust Gas Cleaning System for Marine Diesel Engine Application
Authors: Ryu Younghyun , Kim Taewoo , Kim Jungsik , Nam Jeonggil
Published: October 2020

Global air pollution regulations are becoming stricter for large diesel engines powering automobiles and ships. In the automotive sector, Euro 4 regulations came into force in January 2013 in accordance with European Union (EU) emission standards for heavy-duty diesel engines and are based on steady-state testing. In the marine sector, the International Maritime Organization(IMO) Maritime Environment Protection Committee(MEPC) is a group of experts who discuss all problems related to the prevention and control of marine pollution from ships, such as efforts to reduce ozone-depleting substances and greenhouse gas emissions. To reduce the harmful emissions from marine diesel engines, a wet-type exhaust gas cleaning system was developed in this study. As a test, seawater, electrolyzed water, and sodium hydroxide were sequentially injected into the exhaust gas. SO2 was reduced by 98.7–99.6% with seawater injection, NOx by 43.2–48.9% with electrolyzed water injection, and CO2 by 28.0–33.3% with sodium hydroxide injection.
Climate-Wise Habitat Connectivity Takes Sustained Stakeholder Engagement

Published: October 2020

Well-managed and connected protected area networks are needed to combat the 6th mass extinction, yet the implementation of plans intended to secure landscape connectivity remains insufficient. The failure to translate planning efforts into effective action (i.e., the research-implementation gap) hinders our ability to conserve biodiversity threatened by ongoing climate change and habitat fragmentation. Sustained collaboration between researchers and practitioners to co-produce conservation strategies can bridge this gap by providing end-users with implementation guidance based on legitimate, relevant, and trusted information. However, few case studies capture methods for the co-production and use of climate-wise connectivity knowledge. Here we describe the framework for sustained engagement used by a multi-jurisdictional practitioner network to co-produce climate-wise linkages for the interior coastal ranges in Northern California. We found iterative co-production shaped ecological objectives, input data, analytical methods, and implementation priorities. Stakeholders used both co-produced and local socio-ecological (e.g., development threat, management priorities) knowledge to finalize corridor implementation plans. Priority corridors afforded greater climate benefit and were more likely to connect lands managed by participant organizations. Our results demonstrate how collaborative partnerships can bridge the gap between connectivity research and implementation. Lessons learned, outcomes, and future plans provide insights to advance landscape-scale resilience to climate change.
Numerical Analysis of Convection–Diffusion Using a Modified Upwind Approach in the Finite Volume Method
Authors: Hussain Arafat , Zheng Zhoushun , Anley Eyaya Fekadie
Published: October 2020

The main focus of this study was to develop a numerical scheme with new expressions for interface flux approximations based on the upwind approach in the finite volume method. Our new proposed numerical scheme is unconditionally stable with second-order accuracy in both space and time. The method is based on the second-order formulation for the temporal approximation, and an upwind approach of the finite volume method is used for spatial interface approximation. Some numerical experiments have been conducted to illustrate the performance of the new numerical scheme for a convection–diffusion problem. For the phenomena of convection dominance and diffusion dominance, we developed a comparative study of this new upwind finite volume method with an existing upwind form and central difference scheme of the finite volume method. The modified numerical scheme shows highly accurate results as compared to both numerical schemes.

Published: October 2020

Background and objectives: The use of non-invasive techniques to predict the histological type of renal masses can avoid a renal mass biopsy, thus being of great clinical interest. The aim of our study was to assess if quantitative multiphasic multidetector computed tomography (MDCT) enhancement patterns of renal masses (malignant and benign) may be useful to enable lesion differentiation by their enhancement characteristics. Materials and Methods: A total of 154 renal tumors were retrospectively analyzed with a four-phase MDCT protocol. We studied attenuation values using the values within the most avidly enhancing portion of the tumor (2D analysis) and within the whole tumor volume (3D analysis). A region of interest (ROI) was also placed in the adjacent uninvolved renal cortex to calculate the relative tumor enhancement ratio. Results: Significant differences were noted in enhancement and de-enhancement (diminution of attenuation measurements between the postcontrast phases) values by histology. The highest areas under the receiver operating characteristic curves (AUCs) of 0.976 (95% CI: 0.924–0.995) and 0.827 (95% CI: 0.752–0.887), respectively, were demonstrated between clear cell renal cell carcinoma (ccRCC) and papillary RCC (pRCC)/oncocytoma. The 3D analysis allowed the differentiation of ccRCC from chromophobe RCC (chrRCC) with a AUC of 0.643 (95% CI: 0.555–0.724). Wash-out values proved useful only for discrimination between ccRCC and oncocytoma (43.34 vs 64.10, p < 0.001). However, the relative tumor enhancement ratio (corticomedullary (CM) and nephrographic phases) proved useful for discrimination between ccRCC, pRCC, and chrRCC, with the values from the CM phase having higher AUCs of 0.973 (95% CI: 0.929–0.993) and 0.799 (95% CI: 0.721–0.864), respectively. Conclusions: Our observations point out that imaging features may contribute to providing prognostic information helpful in the management strategy of renal masses.

Published: October 2020

Ready-to-eat (RTE) artisanal foods are very popular, but they can be contaminated by Listeria monocytogenes. The aim was to determine the presence of L. monocytogenes in artisanal RTE foods and evaluate its food safety risk. We analyzed 400 RTE artisanal food samples requiring minimal (fresh products manufactured by a primary producer) or moderate processing (culinary products for sale from the home, restaurants such as small cafés, or on the street). Listeria monocytogenes was isolated according to the ISO 11290-1:2017 standard, detected with VIDAS equipment, and identified by real-time polymerase chain reaction (PCR). A small subset (n = 8) of the strains were further characterized for evaluation. The antibiotic resistance profile was determined by the CLSI methodology, and the virulence genes hlyA, prfA, and inlA were detected by PCR. Genotyping was performed by pulsed-field gel electrophoresis (PFGE). Listeria monocytogenes was detected in 7.5% of RTE artisanal foods. On the basis of food type, positivity in minimally processed artisanal foods was 11.6%, significantly different from moderately processed foods with 6.2% positivity (p > 0.05). All the L. monocytogenes strains (n = 8) amplified the three virulence genes, while six strains exhibited premature stop codons (PMSC) in the inlA gene; two strains were resistant to ampicillin and one strain was resistant to sulfamethoxazole-trimethoprim. Seven strains were 1/2a serotype and one was a 4b strain. The sampled RTE artisanal foods did not meet the microbiological criteria for L. monocytogenes according to the Chilean Food Sanitary Regulations. The presence of virulence factors and antibiotic-resistant strains make the consumption of RTE artisanal foods a risk for the hypersensitive population that consumes them.

Published: October 2020

The zoonotic Onchocerca lupi and tick-transmitted filarioids of the genus Cercopithifilaria remain less well known due to the difficulties in accessing to skin samples as target tissues. Here, we proposed a molecular approach reliying on multiplex qPCR assays that allow the rapid identification of filarioids from canine blood, skin, and tick samples. This includes two newly developed duplex qPCR tests, the first one targeting filarial and C. grassii DNA (CanFil-C. grassii). and the second qPCR assay designed for the detection of Cercopithifilaria bainae and Cercopithifilaria sp. II DNAs (C. bainae-C.spII). The third one is a triplex TaqMan cox 1 assay targeting DNA of blood microfilariae (e.g., Dirofilaria immitis, Dirofilaria repens and Acanthocheilonema reconditum). The novel duplex qPCRs developed were validated in silico and by screening of known DNA collection. The qPCR assays were also used for screening the blood and tick samples of 72 dogs from Algeria. This allowed the identification of canine filariasis infection with 100% of specificity and 89.47% and 100% of sensitivity from naturally infected blood and tick samples, respectively. The prevalences of 26.39% for D. immitis and 5.56% for both D. repens and A. reconditum were reported in blood and tick samples. Cercopithifilaria DNAs were detected only in tick samples, with a prevalence of 4.17% and 5.56% for C. bainae and Cercopithifilaria sp. II, respectively. Co-infections were diagnosed in 6.94% and 13.89% of blood and tick samples, respectively. Whereas all samples were negative for C. grassii DNA. The use of engorged ticks instead of blood and skin samples could be an easier option for the surveillance of all canine filarioids herein investigated. The multiplex qPCR assays herein validated were shown to be useful in the detection of filarial co-infections by overcoming sequencing of positive samples.
Comparative Genome Sequence Analyses of Geographic Samples of Aspergillus fumigatus—Relevance for Amphotericin B Resistance
Authors: Fan Yuying , Wang Yue , Xu Jianping
Published: October 2020

Amphotericin B (AMB) is a major fungicidal polyene agent that has a broad spectrum of action against invasive fungal infections. AMB is typically used as the last-line drug against serious and life-threatening infections when other drugs have failed to eliminate the fungal pathogens. Recently, AMB resistance in Aspergillus fumigatus has become more evident. For example, a high rate of AMB resistance (96%) was noted in the A. fumigatus population in Hamilton, Ontario, Canada. AMB-resistant strains have also been found in other countries. However, the mechanism of AMB resistance remains largely unknown. Here, we investigated the potential genes and mutations associated with AMB resistance using whole-genome sequences and examined AMB resistance distribution among genetic populations. A total of 196 whole-genome sequences representing strains from 11 countries were examined. Analyses of single nucleotide polymorphisms (SNPs) at the whole-genome level revealed that these strains belonged to three divergent genetic clusters, with the majority (90%) of AMB resistant strains located in one of the three clusters, Cluster 2. Our analyses identified over 60 SNPs significantly associated with AMB resistance. Together, these SNPs represent promising candidates from which to investigate the putative molecular mechanisms of AMB resistance and for their potential use in developing rapid diagnostic markers for clinical screening of AMB resistance in A. fumigatus.

Published: October 2020

The paper describes a stable method for multiplexed recording of the Bragg diffraction gratings for waveguides using a phase mask. Diffraction waveguides in this experiment were made of photo-thermo-refractive glass. Two types of the phase mask are considered: surface and volume. Their comparison is based on diffraction characteristics of manufactured single and multiplexed Bragg gratings. The experimental results showed the advantage of surface phase mask application. To confirm the efficiency of the proposed method, diffraction waveguides was successfully fabricated and integrated in see-through near-eye display.

Easy-to-apply and quick methods for evaluate body composition are often preferred when assessing soccer teams. This study aimed to develop new equations for the somatotype quantification that would reduce the anthropometric measurements required by the Heath and Carter method, integrating the somatotype assessment to the bioelectrical impedance analysis (BIA). One hundred and seventy-six male elite soccer players (age 26.9 ± 4.5 years), registered in the Italian first division (Serie A), underwent anthropometric measurements and BIA. Endomorphy, mesomorphy, and ectomorphy were obtained according to the Heath and Carter method, while fat mass (FM) and fat free mass (FFM) estimated using a BIA-derived equation specific for athletes. The participants were randomly split into development (n = 117) and validation groups (n = 59, 1/3 of sample). The developed models including resistance2/stature, FM%, FFM, contracted arm and calf circumference, triceps, and supraspinal skinfolds had high predictive ability for endomorphy (R2 = 0.83, Standard Error of Estimate (SEE) = 0.16) mesomorphy (R2 = 0.80, SEE = 0.36), and ectomorphy (endomorphy (R2 = 0.87, SEE = 0.22). Cross validation revealed R2 of 0.80, 0.84, 0.87 for endomorphy, mesomorphy, and ectomorphy, respectively. The proposed strategy allows the integration of somatotype assessment to BIA in soccer players, reducing the number of instruments and measurements required by the Heath and Carter approach.
Value Frameworks for Vaccines: Which Dimensions Are Most Relevant?
Authors: Luyten Jeroen , Kessels Roselinde , Vandermeulen Corinne , Beutels Philippe
Published: October 2020

In addition to more narrow criteria such as safety, effectiveness and cost-effectiveness, vaccines can also be evaluated based on broader criteria such as their economic impact, contribution to disease eradication objectives, caregiver aspects, financial protection offered, equity or social acceptability. We summarize a survey executed in a sample of the population (n = 1000) in Flanders, Belgium, in which we investigated support for using these broader criteria to evaluate vaccines for funding decisions. By means of both favourable and unfavourable framings of a hypothetical vaccine across 40 value dimensions, we find support for the view that people indeed consider a broad range of medical and socio-economic criteria relevant. Several of these are not incorporated in standard evaluation frameworks for vaccines. The different results we find for different framings highlight the importance of developing a consistent a priori value framework for vaccine evaluation, rather than evaluating vaccines on an ad hoc basis.
Acceso a la jurisdicción contencioso administrativa
Authors: Ledesma Narvaez Marianella
Published: October 2020

Desde una visión clásica de la jurisdicción contencioso administrativa, esta se halla orientada a conocer todas aquellas pretensiones deducidas por los administrados contra los actos de la administración pública sujetos al derecho administrativo; sin embargo, esta tradicional concepción se ha venido superando a favor de concebirla como vía para una verdadera y adecuada tutela jurisdiccional efectiva de los derechos e intereses legítimos de los ciudadanos frente a cualquier acto ilícito de la administración pública, lo que ha generado el incremento del traslado de la discusión de sede administrativa a sede judicial, en atención a que las pretensiones contenciosas no están en función del acto administrativo ni tampoco están condicionadas al contenido de dicho acto, y por tanto, el centro de gravedad en el contencioso administrativo ya no es el acto administrativo en sí, sino los intereses subjetivos de los ciudadanos que se enfrentan a la administración pública
La ética en situaciones de crisis
Authors: Fernández Arce César
Published: October 2020

El Perú, como muchos otros países, atraviesa una grave crisis de valores morales, pues estos han sido trastocados por otros de signo material, estimados en términos de utilidad, conveniencia o provecho personal; ni siquiera los derechos humanos prevalentes han sido un obstáculo para ello. Se hace imperativo, por ello, revalorar esos derechos, ya que constituyen exigencias indispensables de la dignidad humana. Se hace necesario, igualmente, tener en cuenta que el crecimiento económico es fundamental pero no basta; es menester, además, el crecimiento ético de las personas y el fortalecimiento de las instituciones en este ámbito, pues, de otro modo, no tendrá sentido afirmar que la persona humana es un fin en sí misma
Relaciones entre el derecho penal y el derecho civil respecto al delito de hurto en el Código Penal Peruano
Authors: Hurtado Pozo José
Published: October 2020

En el proceso de interpretación y comprensión de los tipos legales referentes a los delitos contra el patrimonio, el aspecto decisivo está relacionado con la función que se atribuya al derecho penal respecto a otras ramas del derecho, en especial al derecho civil. Los factores civiles o comerciales que contienen los tipos legales penales deben ser comprendidos de acuerdo con las limitaciones, fundamentos y finalidades del derecho penal. Sin embargo, las clasificaciones y los criterios de distinción empleados por el derecho civil no siempre concuerdan con las distinciones realizadas en el derecho penal, ni con los fines de las disposiciones penales concernidas, lo cual muestra la relativa autonomía del derecho penal frente al derecho civil.
La Constitución de Cádiz, las elecciones y los municipios
Authors: Andújar Moreno Jorge
Published: October 2020

Este año 2012 se celebran los 200 años —bicentenario— de la Constitución de Cádiz, la primera y única carta política de la monarquía española que consideró como ciudadanos en pie de igualdad a los nacidos en ambos hemisferios. Esto incluía a los criollos, indios y mestizos e inclusive a los analfabetos. Asimismo, el carácter reformista y liberal de la carta gaditana permitió sancionar una serie de libertades y derechos humanos que, con avances y retrocesos, se plasmarían en todas las Constituciones peruanas siguientes, de las cuales se yergue como su necesario antecedente y referente. El reconocimiento del pueblo como fuente de soberanía llevó a plasmar las primeras elecciones populares ediles y parlamentarias. Determinó así el surgimiento de la disciplina del Derecho Electoral. Este ensayo resalta en especial la importancia y la histórica autonomía de los municipios, trasplantados al Perú desde España y surgidos desde antes en Roma. Se reflexiona sobre su evolución constitucional y que a pesar de que han sido reconocidas solemnemente por algunas cartas —como la de Cádiz—, ello tampoco ha garantizado su fiel cumplimiento en los hechos.
Constitución y jurisdicción
Authors: Ferrajoli Luigi
Published: October 2020

Se formula una reflexión teórica sobre la naturaleza y sobre el futuro del entero sistema de garantías, frente a la expansión del ámbito de la jurisdicción equiparable al desarrollo del sistema de límites y deberes legales concedidos a los poderes públicos. A toda expansión de la legalidad debe corresponder una expansión de los espacios de la jurisdicción y, consecuentemente, un crecimiento del poder judiciario que exige a su vez un reforzamiento de sus condiciones de legitimidad. Así, la expresión de la jurisdicción consecuente a la expansión de la legalidad determinada por el paradigma constitucional, permite repensar las fuentes de legitimación del Poder Judicial y de su separación de los otros poderes. Dicho proceso expansivo no se ha agotado y expresa una clara tendencia destinada a desarrollarse ulteriormente; crecimiento que pone en evidencia que el conjunto de las garantías y el rol de la jurisdicción son hoy en día insuficientes respecto a las funciones de protección de los derechos estipulados en las diversas cartas constitucionales estatales y supraestatales, lo que conlleva a la necesidad de repensar, también en el plano teórico, el rol de la jurisdicción.

Published: October 2020

Results of studies on the relationship between the claw morphometric parameters and the carapace width (CW) of the triangle crab (Chionoecetes angulatus) crab from the Sea of Okhotsk presented. For the operational screening and separation of males into morphometrically mature (ММ – large-clawed) and immature (MI – small-clawed) species, it is proposed to use the coefficient of morphometric maturity (K%). This coefficient can be defined as the ratio of claw height to carapace width (KH%) or as the ratio of claw diagonal to carapace width (KD%), expressed as a percentage. When assessing the coefficient of morphometric maturity (K%), the boundary value for KH% is 16, and for KD% it is 35, which allows reliable identification of large-clawed (MM) males at K% values above the boundary values, and small-clawed (MI) males at K% values below the boundary values. Four functional groups were distinguished in males of C. angulatus: 1) MI physiologically immature — CW ≤90 mm, KH% <13.5, and KD% ≤29; 2) MI physiologically mature — CW 90.1–120 mm, KH% 12–16 and KD% 25–35; 3) MI large-sized physiologically sexually mature — CW >120 mm, KH% 13–16 and KD% 29–35; 4) MM morphometrically and functionally mature — CW 74–167 mm, KH% >16 and KD% >35. The correlation of the onset of morphometric maturity with biochemical parameters of hemolymph and with the development of muscle tissue is discussed. For various functional groups of males C. angulatus, an abundance estimate was implemented taking into account the K% coefficient.

La ricezione di Seneca tragico tra Quattrocento e Cinquecento
Authors: Capirossi Arianna
Published: October 2020

The volume investigates the reception of Senecan tragedies during Humanism, focusing on printed editions and on translations in Florentine vernacular language. The first chapter summarizes the manuscript transmission of the tragedies up to the first age of printing, with a glimpse to their possible theatrical representations. The second chapter contains the description of the printed editions from the princeps (before 1478) to the three-comment edition by Josse Bade (1514): I analysed the main paratexts, with a focus on the commentaries by Gellio Bernardino Marmitta, Daniele Caetani, and Josse Bade, and reconstructed the identities of the personalities who contributed to the publication of the tragedies. The third chapter offers a stylistic study of the five vernacular translations produced up to the year 1498. In the volume I publish the translations by Evangelista Fossa (Agamennone) and Pizio da Montevarchi (Hercule furent and Hyppolito), which lacked a modern edition.
Between the Mediterranean and the North Sea: Networks of Men and Ports (14th-15th Centuries)
Authors: Orlandi Angela
Published: October 2020

This essay examines how the various processes of economic integration brought about by commercial exchanges were influenced by networks of merchants, by the different functions and capacities of ports, and by the various locations of routes established between the Mediterranean, the Atlantic and the North Sea. The ports, the routes and ships, and the mentality and culture of the economic operators represent the three main themes of this study; it aims to observe and compare maritime environments which were completely different from one another, especially in terms of the size of the ports and the importance of the commercial itineraries based on them.
Genoa: Colonizing and Colonized City? The Port City as a Pole of Attraction for Foreign Merchants (16th-18th centuries)
Authors: Piccinno Luisa , Zanini Andrea
Published: October 2020

As Michel Balard pointed out with reference to the late Middle Ages and to the relations between Genoa and overseas cities, “Genoa, a colonizer in the East, is colonized by the Orientals”. The aim of this work is to verify whether and to what extent this concept is applicable also to the modern age and whether it involved a wider geographic area than the one examined by this French historian. In particular we outline the features of the presence of foreign merchants in Genoa between the 16th and 18th centuries as a phenomenon complementary to the better known “diaspora” of Genoese businessmen.
Swedish Trade and Shipping in the Mediterranean in the 18th Century
Authors: Müller Leos
Published: October 2020

This paper analyses the rise of Swedish trade and shipping in the Mediterranean in the eighteenth century. It focuses on three factors that shaped Sweden’s role in the area: foreign policy interest, foreign trade policy (mercantilism), and commodity demand and supply. The foreign policy interest is represented by attempts to build an alliance with the Ottoman Empire against Russia. An outcome of this was the short-lived Swedish Levant Company. The second factor relates to Sweden’s mercantilist policy in the Mediterranean, embodied in the Swedish Navigation Act, trade and peace treaties with the North-African states, and the consular services in southern Europe. Sea salt was in the core of this policy—a strategic commodity in northern Europe. Southern Europe, too, was important market for Swedish exports goods: iron, tar and pitch, and planks.

Pendidikan bagi setiap manusia menjadi sebuah ke­butuhan yang sangat penting serta akan menjadi penentu berkembang atau tidaknya sua­tu bangsa ataupun negara. Peningkatan kualitas pendidikan dapat dilihat dari beberapa faktor yang menunjang. Salah satu tolak ukur peningkatan kualitas pendidikan yaitu kualitas pembelajaran. Banyak sekali masalah yang terjadi dalam proses pembelajaran misalnya peran seorang guru yang sangat dominan (Teacher Center), dan siswa hanya dijadikan sebagai objek dalam proses pembelajaran sehingga kurang tercapainya tujuan dalam suatu pembelajaran. Guru dalam proses pembelajaran harus mengaitkan materi yang disampaikan dengan kehidupan sehari-hari siswa (Contextual Teaching And Learning) supaya siswa lebih aktif dan dapat lebih mudah memahami materi yang disampaikan oleh guru. Tujuan penelitian adalah untuk mendeskripsikan pengaruh Contextual Teaching And Learning terhadap hasil belajar siswa pada pembelajaran tematik kelas IV. Jenis penelitian yang digunakan adalah kuantitatif dengan sifat eksperimen dengan menggunakan One-group pretest-posttest design. Untuk mengetahui pengaruh pendekatan Contextual Teaching And Learning dapat dilakukan dengan cara menghitung dan menggunakan uji t (paired sample t test). Hasilnya menunjukkan bahwa nilai sig. (2-tailed) sebesar 0,000 < 0,05, sehingga Ha diterima dan H0 ditolak. Artinya terdapat pengaruh pendekatan Contextual Teaching And Learning Terhadap Hasil Belajar Tematik Siswa Kelas IV SDN 1 Ngepeh Semester Genap Tahun Pelajaran 2019/2020.

PELATIHAN MEMBUAT STATISTIK DESKRIPSI NILAI HASIL BELAJAR SISWA KEPADA GURU-GURU SDN DI WILAYAH TANJUNG GELAM INDERALAYA OGAN ILIR
Authors: Cahyawati Dian
Published: October 2020

Pengolahan nilai hasil belajar siswa yang dilakukan oleh guru sekolah dasar (SD) masih dilakukan secara manual atau dengan menggunakan kalkulator sederhana.Â  Hasil pengolahan nilai dengan cara ini berisiko mengakibatkan kesalahan perhitungan dan hanya menghasilkan informasi yang sedikit mengenai prestasi siswa. Hal ini diakibatkan oleh kurangnya minat dan kemampuan guru SD yang relatif masih kurang dalam hal mengolah dan menyajikan nilai hasil belajar siswa dengan teknologi komputer. Kurangnya minat dan kemampuan guru dalam penggunaan komputer sebagai teknologi untuk membantu perhitungan, yang lazimnya sudah tidak asing lagi bagi semua kalangan, merupakan permasalahan yang perlu dibantu penyelesaiannya.Â  Salah satu jalan keluar untuk permasalahan itu, adalah Â memberikan tambahan wawasan dan kemampuan, mengenai penggunaan komputer, khususnya dalam mengolah nilai hasil belajar siswa dengan statistik deskripsi, melalui kegiatan Pengabdian kepada Masyarakat (PPM). Â Kegiatan ini dilaksanakan dalam bentuk pelatihan, secara tatap muka langsung dengan guru-guru SD, dengan diskusi dan tanya jawab, serta evaluasi bagi peserta. Kegiatan PPM oleh dosen dari Jurusan Matematika FMIPA Universitas Sriwijaya, diberikan kepada guru-guru SD Negeri (SDN) di Wilayah Tanjung Gelam Kecamatan Indralaya, yaituÂ  SDN 02, SDN 06, SDN 10, dan SDN 17.Â  Kegiatan ini telah dilaksanakan di Gedung SDN 06 Indralaya, dihadiri oleh sembilan belas orang guru. Hasil pelaksanaan kegiatan, diperoleh informasi bahwa seluruh peserta memberikan respon yang sangat bagus dan antusias. Peserta menyatakan bahwa proses penilaian hasil belajar siswa, sangatlah penting.Â  Namun demikian, penggunaan statistik deskripsi, belum pernah diterapkan dalam mengolah nilai hasil belajar Â siswa, karena kemampuan peserta dalam menggunakan komputer masih kurang, padahal, hampir 85% peserta guru SDN, sudah tersertifikasi sebagai pendidik di tingkat SD. Secara keseluruhan, kegiatan ini telah berhasil dilaksanakan dan sangat memuaskan baik bagi Tim pelaksana maupun Guru-Guru sebagai peserta.Â  Namun demikian, sangat perlu dipertimbangkan untuk menambah intensitas kegiatan PPM di sekolah-sekolah dasar, sebagai kegiatan pembinaan dari Universitas Sriwijaya.
EFFECT OF ELECTRIC ARC WELDING ON IMPACT OF DIFFERENT MILD STEEL WELD GEOMETRIES
Authors: NL Vaishak , Suhas Suhas , Bhosle Vilas K , T Prashanth
Published: October 2020

The effect of welding parameters (current, electrode diameter) on the impact of low carbon steel specimens was investigated in this work. Two different geometries namely square butt welded joint and double V welded joint were created. The welding operation was carried out at three different current for welding currents of 90, 110 and 130 amps and electrode diameters of 2.5, 3.2 and 4mm respectively. A Charpy impact testing machine was used to evaluate the impact of the welded samples. It was observed that a low current of 90 Amps for all the welding electrode diameters produced high impact values for both the welding geometries. Also, the 3.2 mm electrode diameter was found to be more suitable for welding the square butt and the double V geometry as it yielded higher impact values. Additionally, the double V geometry showed better performance when compared to the square butt geometry for all the combinations of welding currents and electrode
diameters.
Integrability of Differential Equations of Motion of an n-Dimensional Rigid Body in Nonconservative Fields for n = 5 and n = 6
Authors: Shamolin Maxim V.
Published: October 2020

In this review, we discuss new cases of integrable systems on the tangent bundles of finite-dimensional spheres. Such systems appear in the dynamics of multidimensional rigid bodies in nonconservative fields. These problems are described by systems with variable dissipation with zero mean. We found several new cases of integrability of equations of motion in terms of transcendental functions (in the sense of the classification of singularities) that can be expressed as finite combinations of elementary functions.
Methylprednisolone in acute respiratory distress-syndrome in COVID-19: rationales for use, optimal dosage regimens, combined use with tocilizumab
Authors: Mirzaev K. B. , Kiselev Yu. Yu. , Sychev D. A.
Published: October 2020

No robust evidence proving clinical effectiveness of methylprednisolone in acute respiratory distress-syndrome in COVID-19, including combined use with tocilizumab, has been identified. Systemic glucocorticosteroids use may be considered acceptable in such patients in life-threatening situations, when interleukin-6 blockers (tocilizumab, sarilumab) are unavailable.

Published: October 2020

Current use of dipyridamole in COVID-19 is mainly based on its antithrombotic activity, since there is no robust clinical effectiveness data. The decision to use dipyridamole in COVID-19 should be individualized, considering the experimental nature of this treatment.
Assessment of the influence of the environmental factors on the formation and development of logistics systems pharmacy enterprises
Authors: VAVILOVA Viktoriia
Published: October 2020

The object of the research is the processes of formation of logistics systems of pharmacy chains. The important directions of their formation and development are the determination of the optimal size of the network (the number of retail outlets) and territorial distribution (location of pharmacies and pharmacy points). When solving these problems, it is necessary to take into account factors external to logistic systems: demographic, economic, social, and the like. It has been substantiated that the group of demographic factors can include the number and density of the population, the number of pensioners, the birth rate, etc. Economic factors are characterized by indicators of the level of income of the population, the volume of retail trade (including pharmacy) per capita, the intensity of competition, the development of transport infrastructure, etc. The main social factors influencing the formation and development of logistics systems of pharmacy chains are the standard of living of the population, employment of the able-bodied population, the number of medical and preventive institutions in the territory covered by the pharmacy network.
Based on the results of the study of the influence of environmental factors on the formation and development of logistics systems of pharmacy chains, a methodology for assessing the spatial and quantitative parameters of logistics systems of pharmacy chains was developed, which provides for the sequential execution of operations at the national, regional and local levels and allows you to determine promising markets for the development of a pharmacy chain (spatial characteristics of logistics systems), choose the most appropriate option for the location of the pharmacy chain; to determine the optimal number of outlets in logistics systems in local and regional markets, taking into account the internal potential of the network, as well as the size of the pharmacy chain as a whole – at the national level (quantitative characteristics of the logistics systems of pharmacy chains).
Features of the pricing policy in the dental market of Ukraine

Published: October 2020

Dental care is one of the most popular and market-oriented type of care provided to the population. It is developing rapidly, offering advanced medical technologies on the market. But some issues such as market competition in the health services sector, social partnership in dental services delivery to the population are not fully considered.
There are some difficulties in analyzing dental market in Ukraine due to the presence of some problems: lack of official information about amount of dental services; incomplete coverage of information about production of dental services by statistics; a large part of the market for dental services are individuals – entrepreneurs, who are not obliged to publicly information about their commercial results (much of the producers in dentistry (at least 50 %) is in the shadow sector). The aim of the article is to investigate the current state of price aspects of the market of dental services in Ukraine.
The article identifies the main problems in the market of dental services in Ukraine, the characteristics of medical services and factors that affect the formation of prices for these services, and also the aspects that consumers are guided with in choosing a medical institution in today’s competitive environment. In paper we analyzed price and non-price factors of demand for dental services, compared prices for dental services in private and public institutions, calculated their average value. Using standard deviation, we calculated how significant are the differences in prices for dental services within the industry.
The cost of dental treatment in Ukraine depends on many factors: the orientation of the clinic, its form of ownership, popularity and competence of specialists. After performing the analysis, we saw that the prices for the same service differ significantly and vary depending on the company.
Therefore, the dental market is characterized by the emergence of a large number of private dental institutions, where prices range significantly. In these conditions, the issues of modern management and marketing in dentistry have become especially relevant. To ensure the effective functioning of all subjects of the dental market, it is necessary to form their information field, within which they would exchange information about their activities, provide effective communication and work to create and maintain a positive reputation. Therefore, taking into account the current difficult epidemiological, economic and social situation in Ukraine, it is obvious that the health care sector needs constant improvement.
