Vai viegli tulkot Sagānu?
Authors: Skrābane Astra
Published: April 2021

Françoise Sagan’s (1935–2004) work is popular in France and Latvia for two reasons: the world of her characters that draws the reader into a vortex of life cravings and love surprises, and her writing which is classic, clear and seemingly light, but saturated with cultural references and quotes.
If the plot and characters appear to be self-sufficient, the translator has a problem with the titles of Sagan’s novels. When comparing the original to a translation, the writer’s style setting (for example, “Bonjour tristesse” in the Latvian translation “Esiet sveicinātas, skumjas”) or symbolism (for example, “La laisse” in the Latvian translation “Akordi”) is often lost. Sagan’s novels include references to literature, cinema, art, popular in the French society of her time, that make up the intertextuality of the literary works and give an additional dimension and, at the same time, economises on means of artistic expression. A transfer into a cultural environment risks losing some multicoloured layers of the source text. Sagan’s language’s relatively rare findings also lose their originality in translation, turning them into standard phrases.
Thus, it should be concluded that the apparently well-formed, seemingly easily-written works of the French author remain within the so-called “women’s literature” or “French novel” without any indication of the sharpness with which Sagan has seen the brilliance and misery of her environment.
Engineering Aspects and Parameter Evaluation of Ozone Generator

Published: April 2021

This paper introduces the Ozone generator parameters analysis and its engineering design aspects. Practically, Ozone is successfully used in water treatment applications; furthermore, it can be used to treat the secondary system cooling water in nuclear research reactors. The main element in this process is the Ozone generator; it has many parameters that need to be set at its design. These parameters can be divided into those related to the electrical equivalent circuit of corona dielectric barrier discharge (DBD), those associated with injected gas flow between the two electrodes, and those belonging to temperature of the electrodes. This paper is intended to those parameters that are related to the electrical equivalent circuit which has two standard models: linear and nonlinear. In this regard, the determination of the component values of nonlinear model can be achieved very hardly. To handle such determination, the nonlinear model can be approximately treated as a linear model in an approaching fashion. Based on this approximation, Lissajous plot and differential evolution (DE) methodologies are used for the computation of DBD ozone chamber parameters. Additionally, a new theoretical technique will be presented

Published: April 2021

Heating oil in oil pipelines to the required temperature, with the most efficient use of electrical energy,is possible with using of the induction heating method. The most important parameter of induction heating settings is frequency. For each process, there is an optimal frequency range that provides the best technological and economic results. Induction heating of the oil pipeline occurs as follows, if alternating high-frequency current is passed through the windings of the oil pipeline inductor (Fig. 1), an alternating magnetic field is formed, which intersects the metal walls of the oil pipeline and induces eddy currents in them. These currents heat the metal walls of the pipeline to the desired temperature and, accordingly, the oil. MITSUBISHI's VIPM Series Intelligent Power Transistor Modules (IPM), which is a functionally complete product, are currently developed and marketed. These transistor modules are designed for high voltages, currents and power. A frequency converter made on these transistor modules allows to heat large diameter oil pipelines. A prototype IGBT transformer was designed and manufactured. Figure 2 shows a prototype of a frequency converter with a power of 6 kW at frequencies from 2 to 20 kHz. Induction heating of metal was used as a load for the frequency converter
A Efetividade do Direito Fundamental À Saúde À Luz do Estado de Coisas Inconstitucional
Authors: Costa Paulo Victor Rodrigues , Souza Elden Borges
Published: April 2021

O presente artigo visa analisar as graves omissões estruturais relacionadas ao direito fundamental à saúde. Partindo da premissa que o direito à saúde deriva diretamente do direito à vida e da dignidade da pessoa humana, objetiva-se analisar uma possível fundamentação para a intervenção do Poder Judiciário nas políticas públicas. O trabalho utilizará o conceito de ‘’Estado de Coisas Inconstitucional’’ criado pela corte colombiana e aplicado pelo Supremo Tribunal Federal como uma tentativa de analisar as lesões ao direito fundamental à saúde, buscando os motivos que sustentam a existência de uma realidade inconstitucional. Esta situação afeta, principalmente, boa parte da população mais carente do país, que não possui recursos para arcar com um plano de saúde privado, restando contar com o Sistema Único de Saúde. O conceito de Estado de Coisas Inconstitucional sofre severas críticas da doutrina tradicional, principalmente quanto à separação dos poderes. Diante do exposto acima, a intervenção judicial através de Estado de Coisas Inconstitucional resolveria o problema da grave omissão inconstitucional que vem dia a dia lesionando o direito fundamental à saúde sem ferir o postulado da separação dos poderes? O objetivo desse artigo é analisar a realidade inconstitucional que lesiona o direito fundamental à saúde a partir da teoria do Estado de Coisas Inconstitucional, analisando seus os pressupostos, sua legitimidade e seus efeitos. Logo, a importância da pesquisa se dará na implementação do instituto no ordenamento jurídico brasileiro. Por fim, o artigo usará o método qualitativo, partindo de estudos doutrinários, artigos, livros e decisões judiciais.

Penelitian ini bertujuan untuk meneliti permasalahan terkait dengan hukum pengangkatan anak melalui Akta pengakuan pengangkatan anak  yang dibuat oleh Notaris dan mengetahui akibat hukum pengangkatan anak bagi pihak yang tidak memenuhi kewajiban sesuai perjanjian. Penelitian ini menggunakan metode yuridis normatif yang menggunakan sumber  yang diperoleh dari Peraturan perundang-undangan, literatur dan karya tulis ilmiah. Analisa data yang digunakan adalah menggunakan deskriptif analitis yaitu metode yang menggunakan analisis terhadap peraturan perundang-undangan yang berlaku. Hasil penelitian ini dapat disimpulkan pada dasarnya pengangkatan anak harus dengan penetapan Pengadilan, hal tersebut didasarkan pada surat edaran mahkamah agung tanggal 7 April 1979 No. 2 tahun 1979 tentang Pengangkatan Anak dikatakan antara lain bahwa pengesahan pengangkatan anak warga negara Indonesia hanya dapat dilakukan dengan suatu penetapan di Pengadilan negeri, dan tidak dibenarkan apabila pengangkatan anak tersebut dilakukan dengan Akta yang dilegalisir oleh Pengadilan negeri. Sehingga dengan demikian, kasus pengangkatan anak harus melalui penetapan Pengadilan negeri dan Akta yang dibuat dihadapan notaris terkait dengan pengakuan anak hanya bersifat pengikatan terhadap apa yang dikehendaki para pihak secara privat terkait hubungan hukum masing-masing pihak tersebut terhadap pengangkatan anak dan tidak memiliki kekuatan hukum mutlak terkait dengan legalitas status pengangkatan anak tersebut jika tidak didaftarkan dan mendapat penetapan Pengadilan negeri.

Authors: Strafun S.S. , Haiovych V.V. , Kulyk Yu.A. , Lieskov V.H.
Published: April 2021

Summary. Partial tear of the pectoralis major muscle (PMM) is an extremely rare injury, but it needs to be studied.

Objective: to carry out a comparative analysis of the clinic, diagnosis and treatment of patients with complete and partial tears of the PMM.

Materials and Methods. A retrospective analysis of 9 patients with partial tears of the PMM who underwent surgical and conservative treatment at the Department of Microsurgery and Reconstructive Surgery of Upper Extremity of the SI “Institute of Traumatology and Orthopedics of NAMS of Ukraine” (Kyiv) from 2008 to 2018 was performed. The mean age of patients with partial tear of the PMM was 37.4±10.8 years (16 to 42 years); 8 were males and 1 was female. The follow-up period after surgical or conservative treatment was 12±2.8 months. The greatest number of injuries occurred during the bench press exercises – 55.6% (5 patients); on the uneven bars – 22.2% (2 patients) and in everyday life – 22.2% (2 patients).

Results. Follow-up examination revealed that 55.6% (5 patients) had injuries of tendon-muscle transition IIC, 33.3% (3 patients) – of tendon part II D, and 11.1% (1 patient) – of muscle II B according to the Cordasco 2020 classification. All the patients deny taking steroids to increase muscle mass. Surgical treatment was performed within 10-643 days after the injury. Two operated on patients had acute injuries (up to 8 weeks after the trauma), and 3 had chronic injuries (more than 8 weeks after the trauma). The results on both the Quick DASH scale and the Subjective Evaluation of Patients with Pectoralis Major Muscle Injuries Questionnaire were negative in both groups during initial treatment. One year after the treatment, excellent and good results were observed in the operated on group; the conservative group showed unsatisfactory results. We did not note any complications after surgical interventions in operated on group of patients.

Conclusions. Partial tears of the PMM require more careful differentiation and additional examination methods. Physically active patients with isolated tears of the PMM need surgical treatment. Such treatment gives excellent and good results, while conservative treatment – unsatisfactory. Due to the small number of patients in our study, partial PMM tears require further investigation.

Objective. Analysis of the results of using the medial gastrocnemius flap (MGF) in orthopedic patients; highlighting peculiarities of surgical technique.

Materials and Methods. 8 patients (10 cases) who underwent the transposition of the MGF. The age of the patients was 19–74 years (on average 40.5±5.7 years); there were 6 males and 2 females. The list of cases: open fractures – 2 cases, combat injury – 2 patients (3 cases), skin necrosis after osteosynthesis – 3 patients (4 cases), and skin necrosis after total knee replacement – 1 case. The results of treatment were assessed in terms 9 months – 10 years by the Lysholm scale.

Results. Autodermoplasty during MGF transposition was performed in two cases and after a few days in others. In cases with open fractures, the osteosynthesis and external fixators reassembly were done; conversion of osteosynthesis was performed one month after autodermoplasty. In cases of skin necrosis after osteosynthesis and total arthroplasty, the implants were never removed. Knee function according to the Lysholm scale ranged from 70 to 100 points (mean 88.2±3.3).

Conclusions. The transposition of the MGF for the replacement of tissue defects of the anterior surface of the lower leg and knee joint is an effective method in orthopedic surgery, which helps to solve the problem of infectious complications and to save the supporting-kinematic function of the lower extremity.
Intermediary multicentric prospective and comparative analysis of 435 Mobile bearing Total Knee Arthroplasties of Ultra Congruent stabilization mechanism versus Peg and Cam stabilization mechanism A point-in-time analysis of the OrthowaveTM6 database

Published: April 2021

The Rolflex TONIC total knee implant was launched in early 2016. It is a cruciate sacrificing design and offers a choice of 2 cruciate substituting mechanism according to the UC (Ultra-Congruent) concept or to the PS (Postero-stabilisation with peg and cam) concept. The PS choice can be associated to a fixed tibial bearing or to a mobile tibial bearing, while the UC choice can only be associated to a mobile tibial bearing. The international use of UC total knee prosthesis is low: according to the 2019 AJRR report the UC variant was up at 4.5% of use in 2018, while the PS variant accounted for the largest frequency of use at 51.6%. The second most used type of TKA was the cruciate retaining (CR) variant at 43.8% of use. There is currently no CR variant in the Rolflex TONIC portfolio.

In order to inform of any differences in terms of etiology, indications, patient profile, surgical choices, and clinical and functional performance between the PS and the UC cruciate substituting mechanisms, this document will analyze only the mobile bearing variants of the Roflex TONIC UC and PS. The patients implanted with Fixed bearing PS will not be included in this analysis.

A prospective clinical follow-up of the Rolflex TONIC has been organized by the sponsor (Evolutis, Briennon, France) to evaluate the safety and performance of this new device. This study includes the implants used since June 2016 and up to December 2018. The study design will review the patients at 2, 5 and 10 years of follow-up. At the date of this intermediary report, the 2 years review is not yet terminated. The 2 years report is expected for early 2021 when all patients included will show more than 2 years of FU. Therefore, this intermediary analysis should only be viewed as a security control analysis in search for any anticipated deviation in the expected results. The average length of follow- up will remain short until all patients will be reviewed at 2 years of minimal FU, yet it will evidence if any short or mid-term complication occurred, and how good is the recovery of the patients estimated through an IKS and an OXFORD scores.

Authors: Raybulov Sergey , Shokina Yulia
Published: April 2021

The paper presents the results of a study of indicators that characterize the nutritional and biological value of new functional products-canned minced thorny skate with the addition of Atlantic cod – «Meatballs of stingray and cod in tomato sauce» and «Thorny skate and cod in white sauce». The content of 100 g of the product of the main food nutrients, namely, protein – from 8.4 to 10.0 g, fat – from 2.6 to 6.7 g, carbohydrates – from 10.2 to 18.1 g, depending on the recipe, was experimentally established. Studies have confirmed the high content of minor food substance – chondroitin sulfate (CS) – in canned thorny skate from 250 to 270 mg per 100 g of the product, which provides the recommended level of adequate consumption from 35.7 to 38.6%. On the basis of experimental data on the amino acid composition of the protein of new products, the indicators characterizing the biological value are calculated. Based on the results of the study, a reasonable conclusion was made about the high nutritional value and the presence of functional properties in canned thorny skate with the addition of Atlantic cod.

Published: April 2021

The intensity of the Pacific salmon fry migration in the Amur basin depends on the water level and floods; In the clear water of the river Anyuy rolled migration is round-the-clock, but the intensity of migration shifts to the dark time of day. In recent years, the effectiveness of reproduction is not stable, there are "failures" when the number of young people decreases dramatically, which determines the need for constant observations of the stingray for adjustments of catch forecasts. The assessment of the total number of young people sliding into the Amur River basin shows the comparability of the number of natural young and young produced by fish farms, and more research is needed to determine the role and contribution of artificial reproduction.
Four flowering plant species described from Katanga (Democratic Republic of the Congo) are based on specimens collected in Guangxi, China

Published: April 2021

The original set of botanical collections of the agronomist H.A. Homblé is conserved in the herbarium BR. Homblé was one of the first collectors (1911–1913) for the flora of Katanga, Democratic Republic of the Congo. Many Homblé specimens were described as
taxonomic novelties; 107 tropical African plant species are named after him. Before his colonial career in Katanga, Homblé stayed about two years (1909–1911) in Guangxi, China. His incompletely labelled Chinese collections were erroneously considered as collected in Katanga. This
supposed African origin has led to confusion with regard to the identification, and even resulted in the description of four species believed to be new for science. This paper presents and discusses Homblé's collection made in Guangxi, and the assumed novelties in it. Drosera insolita
is a synonym of the Asian Drosera lunata, widespread from India to Australia. Three other species are new synonyms.Caesalpinia homblei is a synonym of the pantropical Caesalpinia bonduc. Digitaria polybotryoides is a synonym of Digitaria abludens, a widespread
species in tropical Asia. Grewia katangensis is the only species that proved to be synonymous with an endemic species, Grewia cuspidatoserrata, only known from S Yunnan, and here reported as a new record for Guangxi. Lysimachia candida and Impatiens chinensis should
be deleted from the list of the Congo Flora. The importance of careful specimen labelling and label interpretation is discussed.

Survey Instrument for Measuring Level of Preparedness amongst Healthcare Personnel in Radiation Emergency
Authors: Salleh Siti Hasliah , Mohamed Yusof Nor Ashikin , Ismail Fadillah
Published: April 2021

Drills and exercises are globally practiced to investigate the level of preparedness towards disaster events. However, these activities are rarely conducted because they require substantial investment, specifically to budget and time. A self-reported survey may serve as an alternative approach, although it may not be as effective as drills and exercises. As part of the survey development process, this article discusses preliminary validation of a survey instrument to measure the level of preparedness towards radiation emergency amongst healthcare personnel. Prior to this validation process, extensive literature reviews pointed out that the instrument consists of three constructs of preparedness, namely readiness, willingness, and ability. A total of seven subject matter experts were invited to judge the contents for verification purposes. Randolph Kappa analysis was then conducted to analyse their judgment to allow irrelevant items to be filtered from the rest prior to any improvements. Initially, the survey instrument consisted of 69 items; however, the analysis omitted 16 of them. The following values for each preparedness construct were: Readiness (0.77), Willingness (0.70), and Ability (0.73). These findings indicate that contents of the instrument are valid. Further analysis should be fulfilled to complete validation process to ensure its practicality prior to using it as an evaluation tool.
THE DISRUPTED RHYTHM OF PUBLIC SPACES UNDER THE COVID-19 LOCKDOWN: A CASE STUDY FROM MUMBAI METROPOLITAN REGION
Authors:   Associate Professor, Department of Geography, University of Mumbai, Mumbai, Maharashtra, India, Sattar Sanjukta
Published: April 2021

The COVID-19 pandemic has paralyzed public life world-wide. The need for maintaining physical/social distance has led to a change in the order and nature of human activities across public spaces. As a result, the usual rhythm of activities in public spaces has come to be disrupted. Taking this into consideration, the study delves into the disrupted rhythm of the urban public spaces under the impact of the COVID-19 pandemic and the consequently imposed lockdown. By adopting a case study-based approach, an in-depth analysis has been carried out to comprehend the change in the daily rhythm of a local road in the wake of the pandemic and lockdown. Lefebvre’s technique of ‘rhythmanalysis’ has been applied to carry out this study, as it is highly suited in studying the flow of everyday life in a spatiotemporal context. The article traces the change in the rhythm of activities in the study area during the pandemic and lockdown in comparison to the usual rhythm of activities that existed in the area before the pandemic. The findings of the study reveal that the pandemic has taken a toll on the study area, where the pre-existing rhythm of the public space has been overtaken by a disrupted rhythm that has given rise to chaos and confusion.

In this work the synthesis process of soluble polymethylsilsesquioxane that is a valuable prepolymer in the production of ceramic products, high-temperature protective coatings for high-speed aircraft, primary product for the formation of LEDs and other elements of microelectronics was studied. The synthesis was carried out from methyltrichlorosilane in a binary system of polar and non-polar solvent under the water action. The possibility of polymethylsilsesquioxane with a sufficiently high seepage at atmospheric pressure synthesis was shown. The resulting compound was analyzed. The presence of polymethylsilsesquioxane bonds in the polymer was identified by infrared Fourier spectroscopy on the Bruker Tensor 27 spectrometer. The resulting polymer has all the characteristics of polymethylsilsesquioxane. This is confirmed in particular by the presence of a characteristic wide band over the range by 1050-1100 cm-1 in the spectrum. To find out the optimal synthesis conditions and obtain the maximum yield of polymethylsilsesquioxane, the experiment was planned using the Box-Wilson planning method. The influence of temperature, reaction time and nature of solvents on the yield of polymethylsilsesquioxane was also studied. The optimal conditions for the synthesis were found out. The highest yield of polymethylsilsesquioxane was observed at 10 °C with a 6 hours synthesis duration. When the temperature increased to 30 °C, a partial decrease in the polymer yield was observed. It is assumed that at a high temperature and a significant time of the process, a partial decrease in the yield of polymethylsilsesquioxane associated with a decrease in the soluble fraction begins to occur.

The synthesis of new derivatives of 3-azabicyclononan is one of the urgent tasks of modern synthetic organic chemistry. 3-Azabicyclononan is a structural analogue of the cytisine alkaloid, which is a strong agonist of acetylcholine receptors. Among synthetic heterocycles containing a 3-azabicyclo[3.3.1]nonane fragment, compounds with different types of biological activity have been discovered at present: analgesic, anti-inflammatory, antimicrobial, antioxidant, and others. The introduction of a fragment of azabicyclononan into the amino acid structure can lead to a limitation of the conformational mobility of a new molecule, as a result of which the activity and selectivity of its interaction with the receptor will increase. We synthesized 2-(1,9-dinitro-8-oxo-6,11-diazatricyclo[7.3.1.02,7]trideca-2,4,6-trien-11-yl)acetic acid and 2-(1,9-dinitro-8-oxo-13-(2-oxopropyl)-6,11-diazatricyclo[7.3.1.02,7]trideca-2,4,6-trien-11-yl)acetic acid by the interaction of annionic σ-complexes 5,7-dinitro-8-hydroxyquinoline with glycine under Mannich condensation in high yield. At the beginning, when 5,7-dinitro-8-hydroxyquinoline NaBH4 was applied in DMF or acetone carbanion in DMSO, the corresponding anionic complexes were synthesized. The resulting adducts were isolated from the reaction mixture, dissolved in cold water, and an aminomethylating mixture consisting of formaldehyde and an amino acid was added. As a result, 3-azabicyclo[3.3.1]nonane derivatives are formed, annelated with a pyridine ring and containing an amino acid residue. By the methods of NMR and IR spectroscopy, as well as high-resolution mass spectrometry, the structure of the obtained compounds was proved. Thus, in the 1H NMR spectra of the synthesized compounds, a signal of the proton of the carboxyl group in the form of a broadened singlet is detected in a weak spectral region. Equatorial and axial protons of an alicyclic fragment form a characteristic system of signals in the range δ 3.20-3.60 ppm. In the IR spectra of these molecules, the vibrational bands of carbonyl groups at ν 1720 cm–1, as well as the vibrational bands of the C–O bond of the carboxyl group at ν 1198 cm–1, are fixed. The m/z values in the high resolution mass spectra correspond to the molecular weights of the synthesized diazatricycclotridecans.

A lo largo de estos años, la Corte se ha consolidado como un mecanismo eficaz de solución de controversias internacionales, sin embargo, pasados estos tres cuartos de siglo, ha llegado el momento de identificar cuales son los aspectos que deberían actualizarse para que continuara manteniendo su utilidad a lo largo del siglo XXI. La sociedad internacional ha evolucionado mucho desde que la Corte comenzó a funcionar, por lo que considero llegado el momento de plantearse sus fortalezas y debilidades con el propósito de reforzar las primeras y subsanar las segundas con el único objetivo de adaptar este mecanismo de solución de controversias a los retos que habrá de abordar en el futuro próximo.

A pesar de la tecnología avanzada necesaria para su funcionamiento, los drones representan otra etapa en la tradición humana de desarrollar medios para hacer la guerra a distancia. Así, no se distinguen de otros avances y están sujetos a los mismos estándares internacionales y deben cumplir con los mismos principios que otras plataformas de armas. Este artículo se centra en dar una respuesta sobre la legalidad del uso de drones en relación con el Derecho Internacional Humanitario. Para ello, aborda brevemente el tema del uso de drones en el escenario más común, ataques contra grupos armados no estatales en territorio extranjero, y luego se concentra en el cumplimiento de los principios del derecho internacional humanitario, para concluir que sus características no sólo les permiten cumplir, sino que incluso pueden ser consideradas como una mejora en la búsqueda constante de cumplir con el Derecho Internacional Humanitario.

Published: April 2021

Coma Berenices (Coma Ber), an open cluster about the same age as Praesepe and the Hyades (700–800 Myr) is, despite being only 85 pc away, less well studied than its famous cousins. This is due principally to its sparseness and low proper motion, which together made Coma Ber’s membership challenging to establish pre-Gaia. We have curated a new list of its members based on Gaia DR2 astrometry, derived its metallicity and interstellar reddening using LAMOST data, and inferred the cluster’s age by fitting PARSEC isochrones to its color–magnitude diagram. We then measured rotation periods for Coma Ber’s low-mass members using TESS and ZTF photometry. Our isochrone fitting and the TESS- and ZTF-derived rotation periods confirm that Coma Ber is coeval with the Hyades and Praesepe. This work is the first step toward re-establishing Coma Ber as another valuable benchmark cluster for age–rotation–activity studies.

Introduction: The aim of this study is to investigate whether macrophage migration inhibitory factor (MIF) predicts the prognosis of COVID-19 disease.

Methodology: This descriptive and cross-sectional study was conducted on 87 confirmed COVID-19 patients. The patients were separated into two groups according to the admission in the ICU or in the ward. MIF was determined batchwise in plasma obtained as soon as the patients were admitted. Both groups were compared with respect to demographic characteristics, biochemical parameters and prediction of requirement to ICU admission.

Results: Forty seven patients in ICU, and 40 patients in ward were included. With respect to MIF levels and biochemical biomarkers, there was a statistically significant difference between the ICU and ward patients (p< 0.024). In terms of ICU requirement, the cut-off value of MIF was detected as 4.705 (AUC:0.633, 95%CI:0.561-0.79, p= 0.037), D-dimer was 789 (AUC:0.779, 95%CI: 0.681-0.877, p= 0.000), troponin was 8.15 (AUC: 0.820, 95%CI:0.729-0.911, p= 0.000), ferritin was 375 (AUC: 0.774, 95%CI:0.671-0.876, p= 0.000), and lactate dehydrogenase (LDH) was 359.5 (AUC:0.843, 95%CI: 0.753-0.933, p= 0.000). According to the logistic regression analysis; when MIF level > 4.705, the patient’s requirement to ICU risk was increased to 8.33 (95%CI: 1.73-44.26, p= 0.009) fold. Similarly, elevation of troponin, ferritin and, LDH was shown to predict disease prognosis (p< 0.05).

Conclusions: Our study showed that MIF may play a role in inflammatory responses to COVID-19 through induction of pulmonary inflammatory cytokines, suggesting that pharmacotherapeutic approaches targeting MIF may hold promise for the treatment of COVID-19 pneumonia.

Introduction: This paper aims to estimate the incubation period and serial intervals for SARS-CoV-2 based on confirmed cases in Jiangxi Province of China and meta-analysis method.

Methodology: Distributions of incubation period and serial interval of Jiangxi epidemic data were fitted by “fitdistrplus” package of R software, and the meta-analysis was conducted by “meta” package of R software.

Results: Based on the epidemic data of Jiangxi, we found the median days of incubation period and serial interval were 5.9 days [IQR: 3.8 – 8.6] and 5.7 days [IQR: 3.6 – 8.3], respectively. The median days of the infectivity period at pre-symptomatic was 1.7 days [IQR: 1.1 – 2.4]. The meta-analysis based on 64 papers showed the pooled means of the incubation period and serial interval were 6.25 days (95% CrI: 5.75 – 6.75) and 5.15 days (95% CrI: 4.73 – 5.57), respectively.

Conclusions: Our results contribute to a better understanding of COVID-19 and provide useful parameters for modelling the dynamics of disease transmission. The serial interval is shorter than the incubation period, which indicates that the patients are infectious at pre-symptomatic period, and isolation of detected cases alone is likely to be difficult to halt the spread of SARS-CoV-2.

Published: April 2021

Many regions of the world remain unexplored in terms of the tardigrade diversity, and the islands of the Indian Ocean are no exception. In this work, we report four species of the family Echiniscidae representing three genera from Mauritius, the second largest island in the Mascarene Archipelago. Two species belong in the genus Echiniscus: Echiniscus perarmatus Murray, 1907, a pantropical species, and one new species: Echiniscus insularissp. nov., one of the smallest members of the spinulosus group and the entire genus, being particularly interesting due to the presence of males and supernumerary teeth-like spicules along the margins of the dorsal plates. The new species most closely resembles Echiniscus tropicalis Binda & Pilato, 1995, for which we present extensive multipopulation data and greatly extend its distribution eastwards towards islands of Southeast Asia. Pseudechiniscus (Meridioniscus) mascarenensissp. nov. is a typical member of the subgenus with elongated (dactyloid) cephalic papillae and the pseudosegmental plate IV’ with reduced posterior projections in males. Finally, a Bryodelphax specimen is also recorded. The assemblage of both presumably endemic and widely distributed tardigrade species in Mauritius fits the recent emerging biogeographic patterns for this group of micrometazoans.

We describe a new species of marsupial frog, genusGastrotheca, using morphological characters and molecular data as lines of evidence. The new species was discovered in the páramo and the ecotone between páramo and humid montane forest of Cordillera de Colán, at elevations between 3136 and 3179 m a.s.l., in northeastern Peru. The new species is distinguished from all its congeners by the combination of the following characters: coarsely granular skin on dorsum, a green dorsal coloration without pattern, finger I shorter than finger II, turquoise iris, and a venter without blotches, flecks or dots. Furthermore, we include a detailed osteological description of the newGastrothecaspecies based on Micro-CT scanning. Based on our phylogenetic analyses, the new species belongs to theGastrotheca marsupiataspecies group, is sister toG. oresbiosand closely related toG. psychrophila,G. spectabilis,G. stictopleuraand one undescribed species. Additionally, we test for the presence of the fungal pathogenBatrachochytrium dendrobatidis(Bd). NoBdinfection was detected forG. gemmasp. nov. specimens butBdprevalence was detected among syntopic frogs.

Due to the pandemic crisis, online learning and teaching have become a new normal activity. This study explores a popular and flexible learning media for students in areas with low internet penetration. This paper presents alternative learning using social media and the difference between before and during the crisis. This article has found a change in social media usage as a communication and socialization medium to a learning medium. The three learning methods of social media usage are as follows: question and answer; questioning, and collecting assignments. Social media was chosen because of its popularity and flexibility for both lecturers and students. The aspects of accessibility (cost and connectivity) are a challenge in the development of online learning. Social media is proven to be effective and efficient in conveying messages and to achieve learning objectives

Published: April 2021

The evolution of mobile technologies in learning, has been increased the requirements for developing appropriate usability model to fall into the same line with mobile learning applications. Usability of mobile learning applications is a topic that is into research, this paper focuses a tailored designed model called (M-UTUAT) mobile usability model that combines People at the Centre of Mobile Application Development (PACMAD) and the unified theory of acceptance and use of technology (UTAUT) to form a more robust model. As an addition to the usability research, an application (ICT) was developed for children with speech delays and children diagnosed with autism spectrum. The application is a mobile/tablet-based application that developed according to mobile usability measures to get the maximum learning skills and abilities to help autistic children. It has been designed according to the needs of the children specific to their category and skills. The autism spectrum is a broad spectrum with high and low disabilities. The application consists of both visual and audio aids to help children feel comfortable and associate objects more easily with their original meaning and connections. (PECS) is one of the most common techniques that have been clinically proven to be effective in such cases. This application helped an individual with autism spectrum as well as children with speech delays or disabilities to communicate and correlate faster and easily. The application can help so many families by constructing a more communicative path for people with disabilities. The application is innovative that it developed in the Arabic language to serve Arabic learners as most of the autistic applications available serve English learners. Results gathered after questionnaire highlight the usability issues with the (ICT) application. We developed an app to overcome usability issues.

COVID-19 has emerged as one of the most devastating and clinically significant infectious diseases of the last decade. It has reached global pandemic status at an unprecedented pace and has placed significant demands on health care systems worldwide. Although COVID-19 primarily affects the lungs, epidemiologic reports have shown that the disease affects other vital organs of the body, including the heart, vasculature, kidneys, brain, and the hematopoietic system. Of importance is the emerging awareness of the effects of COVID-19 on the cardiovascular system. The current state of knowledge regarding cardiac involvement in COVID-19 is presented in this article, with particular focus on the cardiovascular manifestations and complications of COVID-19 infection. The mechanistic insights of disease causation and the relevant pathophysiology involved in COVID-19 as they affect the heart are explored and described. Relevant practice essentials and clinical management implications for patients with COVID-19 with a cardiac pathology are presented in light of recent evidence.
