To estimation of the Energy Efficiency Design Index (EEDI) for a ship with energy-saving wing devices
Authors: Рождественский К.В. , Зин М.Х. 
Published: June 2021

В статье приводится оценка индекса проектной энергетической эффективности (EEDI) для судна с энергосберегающими крыльевыми устройствами на встречном регулярном волнении. Вначале на основе предыдущих работ авторов с применением линейной теории поперечных сечений определяются характеристики продольной (вертикальной и килевой) качки судна без крыльев, и такого же судна с крыльями большого удлинения, установленными на днище вблизи оконечностей с целью преобразования волновой энергии в дополнительную тягу. После определения параметров качки судна с крыльями как твердого тела, с применением теории Теодорсена колеблющегося профиля определяется средняя по периоду тяга энергосберегающих крыльевых элементов, совершающих поступательно-вращательные колебания. С другой стороны, в статье находится общее сопротивление системы «судно-крыльевые элементы». При этом применяется метод Холтропа в сочетании с теорие Бейкельмана-Герритсмы. Последняя дает возможность произвести оценку дополнительного волнового сопротивления по найденным параметрам продольной качки судна с крыльями и без крыльев. Затем оценивается значение индекса проектной энергетической эффективности (EEDI) контейнеровоза, снабженного энергосберегающими крыльями на встречном волнении. Исследование показывает, что установка на днище крыльевых элементов может использоваться как один из способов сокращения выброса углекислого газа и уменьшения в соответствии с требованиями Международной морской организации ИМО, значения индекса EEDI для репрезентативных морских условий.
In this paper an estimation is presented of the Energy Efficiency Design Index (EEDI) for a ship with energy-saving wing devices in headwind regular waves. At first, based on previous works of the authors, there are determined with use of linear strip theory the characteristics of longitudinal (heaving and pitching) motions of a ship without wings and identical ship equipped with wings of large aspect ratio fitted on the bottom near extremities for the purpose of converting wave energy into additional thrust. After motions of the ship with wings as a solid boy are determined Theodorsen theory of oscillating foil is applied to calculate period averaged thrust of energy-saving wing elements, performing combined heave-pitch oscillations. On the other hand, the paper addresses the problem of determining overall drag of the “wing-plus-wings” system with use of Holtrop method combined with Beikelmann-Gerritsma theory. The latter enables carrying out an estimation of additional wave resistance based on the calculated parameters of the ship longitudinal motions with and without wings. Then follows an estimation of the EEDI for a containership equipped with wings in headwind regular waves. The study shows that fitting wing elements on the ship bottom can be seen as one of the methods for decreasing the magnitude of the EEDI for representative sea conditions as per requirements of the International Maritime Organization.

Abstract
The Galactic interstellar medium hosts a significant magnetic field, which can be probed through the synchrotron emission produced from its interaction with relativistic electrons. Linearly polarized synchrotron emission is generated throughout the Galaxy and, at longer wavelengths, modified along nearly every path by Faraday rotation in the intervening magneto-ionic medium. Full characterization of the polarized emission requires wideband observations with many frequency channels. We have surveyed polarized radio emission from the Northern sky over the range 1280–1750 MHz, with channel width 236.8 kHz, using the John A. Galt Telescope (diameter 25.6 m) at the Dominion Radio Astrophysical Observatory, as part of the Global Magneto-Ionic Medium Survey. The survey covered 72% of the sky, decl. −30° to +87° at all R.A. The intensity scale was absolutely calibrated, based on the flux density and spectral index of Cygnus A. Polarization angle was calibrated using the extended polarized emission of the Fan Region. Data are presented as brightness temperatures with angular resolution 40′. Sensitivity in Stokes Q and U is 45 mK rms in a 1.18 MHz band. We have applied rotation measure synthesis to the data to obtain a Faraday depth cube of resolution 150 rad m−2 and sensitivity 3 mK rms of polarized intensity. Features in Faraday depth up to a width of 110 rad m−2 are represented. The maximum detectable Faraday depth is ±2 × 104 rad m−2. The survey data are available at the Canadian Astronomy Data Centre.
Database of summer fish fauna sampled in river estuaries in the southern part of the Boso Peninsula, Japan
Authors: Itsukushima Rei , Kano Yuichi 
Published: June 2021

River estuaries provide various ecosystem services, such as nutrient circulation, climate change mitigation, habitats and coastal defence. Information on the various taxonomic groups is collected from large-scale estuaries; however, few studies have focused on river estuaries of small and medium-sized rivers. In particular, information on river estuaries in peninsulas and islands with complex marine environments is lacking.
This paper provides basic information on summer fish fauna in the southern part of the Boso Peninsula, Japan. The Boso Peninsula is located at the northernmost point of where the warm current (Kuroshio) reaches and is considered to have highly endemic fish fauna. In total, 28 families, 51 species and 2,908 individuals were collected from the 27 river estuaries. The data are all accessible from the document “database_fish_estuary_boso (http://ipt.pensoft.net/manage/resource.do?r=database_fish_estuary_boso)”. Further, Sicyopterus japonicus and Microphis brachyurus, which appear in estuaries that are influenced by the Kuroshio, were confirmed. However, these species were confirmed in few of the rivers studied, highlighting the importance of habitat conservation.

Published: June 2021

Introduction: The relationship of numerous metabolic shifts, disorders of hepatocytes functional activity resulting from hypoxia and toxic liver damage with the function of the immune system has not been sufficiently studied so far, nor have the most effective methods of pharmacological correction been established.
Materials and Methods: The studies were carried out on 603 mature male Wistar rats and 45 mice. Acute toxic liver damage (ATLD) was modeled by intramuscular introduction of carbon tetrachloride; acute liver ischemia (ALI) was caused by clamping the hepatoduodenal ligament for 20 minutes; chronic alcohol intoxication (CAI) was modeled by forced intragastric administration of 20% ethanol solution for 60 days. Isolation of xenogeneic (murine) and allogeneic (rat) hepatocytes from newborn mice and rats was carried out according to the method of Berry and Friend (1969); culture fluid of hepatocytes and its protein fractions were prepared according to our developed techniques. The obtained biological material was intraperitoneally introduced into the rats with ATLD, ALI, and CAI.
Results and Discussion: In all the models of the liver damage, there developed morphological and biochemical signs of the liver damage, impaired congenital and adaptive immunity, oxidative stress, increased lipid peroxidation processes.
Conclusion: The introduction of allogeneic hepatocytes, culture fluid obtained on their basis,and proteins isolated from it with MW less than 130 kDa to the recipients with toxic and ischemic liver damage more effectively corrects the pathologic changes in the liver in comparison with xenogeneic hepatocytes, their culture fluid and pharmacological preparations (combinations of Essentiale N and Hypoxenum or Heptral and Mexicor).

Authors: Reyes-Capo Daniela P. , Yannuzzi Nicolas A. , Smiddy William E. , Flynn Harry W. ,   the Endophthalmitis/Anti-VEGF Study Group
Published: June 2021

BACKGROUND AND OBJECTIVE:
To report the incidence and clinical features of infectious endophthalmitis after intravitreal (IV) injection of anti-vascular endothelial growth factor inhibitors (VEGF) between 2018 and 2020 and to compare to prior rates.

PATIENTS AND METHODS:
Retrospective analysis of patients with endophthalmitis after anti-VEGF IV injections treated at Bascom Palmer Eye Institute between January 1, 2018, and December 31, 2020.

RESULTS:

Between 2018 and 2020, the rate of clinically diagnosed endophthalmitis was 0.014% (10/71,858) and of culture-positive was 0.008% (6/71,858). Clinically diagnosed endophthalmitis rates per injection were: aflibercept (0.022%); ranibizumab (0.019%); bevacizumab (0%); and brolucizumab (0%). Clinically diagnosed endophthalmitis rates were similar in the present study compared to those from 2005 to 2017 (
P
= .84). Fifteen eyes were diagnosed with endophthalmitis (10 in-house, five external referrals). Of culture-positive eyes, the organisms were coagulase-negative
Staphylococcus
(8/11),
Streptococcus
species (2/11), and
Abiotrophia defectiva
(1/11). A universal face-masking policy in 2020 did not lower infection rates (
P
= .73).

CONCLUSION:
Endophthalmitis rates after IV anti-VEGF remain low and are similar to prior reports.

Las estructuras portuarias del Patio de Banderas del Alcázar de Sevilla y el emporium de Hispalis
Authors: Tabales Rodríguez Miguel Ángel , García Vargas Enrique 
Published: June 2021

Se describen en este trabajo las estructuras portuarias de época romana excavadas entre 2009 y 2014 en el llamado Patio de Banderas del Alcázar de Sevilla (la antigua colonia Romula Hispalis). Dentro de la compleja estratigrafía del solar, el artículo se centra en las fases constructivas datadas entre finales del siglo II a. C. y el primer tercio del siglo III d. C. Tras una ocupación republicana inicial (fase republicana I) consistente en un edificio productivo, probablemente una almazara, se construye un complejo de almacenes portuarios (fase republicana II) cuya fecha fundacional está dentro del tercer cuarto del siglo I a. C. y cuya destrucción súbita tiene lugar en los primeros decenios del siglo III (fase Imperial II). Tras un recorrido sin apenas modificaciones (fase Imperial I), hacia el último tercio del siglo I d. C. (fase Imperial II) se documenta una importante reforma interior de las estructuras para adecuarlas en su parte septentrional a una función artesanal relacionada con el uso abundante del agua. La destrucción del conjunto se relaciona con un evento energético que, no obstante, parece repercutir sobre un sector de la ciudad ya en decadencia desde finales del siglo II d. C. Finalmente, el trabajo trata de contextualizar las estructuras excavadas en el Patio de Banderas dentro del contexto portuario de la ciudad y en relación a almacenes y conjuntos edilicios similares del resto del Imperio.

Published: June 2021

Abstract
Presented is a temperature and geometry scalable 800°C Silicon Carbide (SiC) Junction Field Effect Transistor (JFET) compact device model designed to simulate the small signal effects of the SiC JFET-R process developed by NASA Glenn Research Center. With the JFET-R process pushing the temperature limits of integrated circuits, a high-fidelity device model capable of predicting the performance over temperature and geometry is required to realize the thermal ruggedness this process provides. A high temperature (HT) packaging system was utilized to characterize a SiC JFET device up to 800°C with a dwell time of 9 hours during a single test. Invaluable device characterization data was obtained and utilized to extend the device model presented to simulate SiC JFET performance continuously over 800°C.
The epsilon constant conjecture for higher dimensional unramified twists of (1)
Authors: Bley Werner , Cobbe Alessandro 
Published: June 2021

AbstractLet
$N/K$
be a finite Galois extension of p-adic number fields, and let
$\rho ^{\mathrm {nr}} \colon G_K \longrightarrow \mathrm {Gl}_r({{\mathbb Z}_{p}})$
be an r-dimensional unramified representation of the absolute Galois group
$G_K$
, which is the restriction of an unramified representation
$\rho ^{\mathrm {nr}}_{{{\mathbb Q}}_{p}} \colon G_{{\mathbb Q}_{p}} \longrightarrow \mathrm {Gl}_r({{\mathbb Z}_{p}})$
. In this paper, we consider the
$\mathrm {Gal}(N/K)$
-equivariant local
$\varepsilon $
-conjecture for the p-adic representation
$T = \mathbb Z_p^r(1)(\rho ^{\mathrm {nr}})$
. For example, if A is an abelian variety of dimension r defined over
${{\mathbb Q}_{p}}$
with good ordinary reduction, then the Tate module
$T = T_p\hat A$
associated to the formal group
$\hat A$
of A is a p-adic representation of this form. We prove the conjecture for all tame extensions
$N/K$
and a certain family of weakly and wildly ramified extensions
$N/K$
. This generalizes previous work of Izychev and Venjakob in the tame case and of the authors in the weakly and wildly ramified case.
Clonidine as an adjuvant to bupivacaine in spinal anaesthesia for infra-umbilical surgeries in children: a prospective randomized, double-blind trial
Authors: Kamal Geeta , Piplani Raman , Gupta Anju , Sehgal Nidhi 
Published: June 2021

Objective: Spinal anaesthesia (SA) is a well-established technique for infra-umbilical surgeries but is underutilized in children. One important reason is the limited duration of action. Clonidine is a useful adjuvant in this regard but has not been studied in a dose of 1.5 μg/kg.Design: a prospective randomized study
Setting: A single centre study conducted at a Super speciality paediatric tertiary care centre.Participants: Sixty children (5-12yrs) scheduled for lower abdominal surgery with duration <90min were included.Interventions: The participants were randomized into two groups to receive 0.4mg/kg of 0.5% hyperbaric bupivacaine with clonidine 1.5μg/kg (Group-I, n=30) or 0.4mg/kg of 0.5% hyperbaric bupivacaine with saline(Group-II, n=30) in the subarachnoid block.Main outcome measures: The sensory and motor block duration, time to two-segment regression, time to first rescue analgesic, and the number of rescue doses required were recorded.Results: Mean duration of sensory blockade (147.5±7.28 vs 310.33±10.17min; P<0.001) and motor blockade (132.5±10.06 vs 283.33±11.77min; P < 0.001) and duration of analgesia (172±9.61 vs 364.50±28.75min; P < 0.001) were significantly prolonged in the clonidine group. In the control group, most patients needed three analgesic doses over 24hr while in the clonidine group, the majority needed two doses. Adverse effects were infrequent in both groups.Conclusions: Clonidine as an adjuvant to 0.5% hyperbaric bupivacaine significantly prolonged the duration of analgesia with improved quality of anaesthesia while maintaining safety. We recommend the routine use of clonidine 1.5 μg/kg dose as an adjuvant to 0.5% bupivacaine in paediatric SA.

Authors: Benavides Vázquez Francisco 
Published: June 2021

A lo largo de la historia de la Orden Hospitalaria son muchas las epidemias y pandemias que le ha tocado afrontar con creatividad, entrega y excelencia. En este estudio se realiza un análisis histórico de las diferentes epidemias afrontadas por los Hermanos de San Juan de Dios desde 1580 con la epidemia de “catarro, la llegada de la peste en el siglo XVII, el tifus, la cooperación entre del Hermano Chaparro y el Dr. Balmis contra la viruela, la fiebre amarilla, el cólera y la heroica actuación de los Hermanos liderada por Benito Menni O.H. en la campaña anticolérica a finales del siglo XIX; hasta la propagación de epidemias más recientes como el VIH en la década de los ochenta, la repercusión social con el Ébola en el 2014 y el fallecimiento de numerosos Hermanos y colaboradores en los centros hospitalarios de África, y finalmente, la actual Covid-19 que amenaza nuestra sociedad.
En este artículo, se refleja como los Hermanos y colaboradores se han volcado en el cuidado de los más vulnerables y en la lucha contra las diversas enfermedades que han asolado a millones de poblaciones durante casi 500 años, siguiendo el ejemplo de san Juan de Dios.
En cada una de estas pandemias, la Orden Hospitalaria con determinación y humanización ha sabido afrontar y aplica los principios más fundamentales de la institución en cada uno de los delicados momentos socio-sanitarios que en este estudio se muestran.
Bencana Covid-19: Stresor bagi Pasangan Suami Istri di Indonesia
Authors: Winurini Sulis 
Published: June 2021

The Covid-19 disaster has become a stressor for married couples because it triggers economic, psychological problems, and increases the burden of household domestic work. The purpose of this paper is to get a picture of the stress of married couples in Indonesia facing the Covid-19 pandemic and an overview of their strategies to deal with it. To fulfil this objective, the researcher used the literature review method which was later analyzed using the theory of stress and disasters. The Covid-19 disaster has proven stressful for married couples in Indonesia. However, most of them still try to maintain their marriage. This is in line with Bowlby’s theory that people respond to stress by seeking closeness with their loved ones, getting together, and supporting each other through stress, maintaining marital bonds. Home is recognized as the safest way to avoid threats as well as a place to focus on happiness with family. AbstrakBencana Covid-19 menjadi stresor bagi pasangan suami istri karena memicu permasalahan ekonomi, psikis, serta bertambahnya beban pekerjaan domestik. Tujuan dari tulisan ini adalah untuk mendapatkan gambaran stres pasangan suami istri di Indonesia menghadapi pandemi Covid-19 dan gambaran strategi mereka untuk mengatasinya. Untuk memenuhi tujuan ini, peneliti menggunakan metode tinjauan pustaka untuk kemudian ditelaah dengan menggunakan teori stres dan bencana. Bencana Covid-19 terbukti membuat pasangan suami istri di Indonesia menjadi stres. Namun demikian, sebagian besar dari mereka tetap berupaya mempertahankan pernikahan. Hal ini sejalan dengan teori Bowlby bahwa orang-orang merespons stres dengan mencari kedekatan bersama orang-orang yang mereka cintai, berkumpul bersama, dan saling mendukung melalui stres, mempertahankan ikatan pernikahan. Rumah disadari menjadi cara paling aman untuk menghindari ancaman sekaligus menjadi tempat untuk memusatkan kebahagiaan bersama keluarga.
