Projection of Hospitalization by COVID-19 in Brazil Following Different Social Distancing Policies (Preprint)
Authors: Silva Henrique , Pereira Sr Rafael , Gritz Sr Raquel , Simões Sr Adolfo , Porto Sr Fabio
Published: June 2020

BACKGROUND

Following the first infections in the Wuhan City, COVID-19 became a global epidemic as declared by the World Health Organization (WHO). Since it is an airborne disease transmitted between humans many countries adopted a quarantine on their own population as well as closing borders. In Brazil many are discussing the best way to handle the epidemic moving forward. Since one of the reasons for the quarantine is to slow the spread of the disease so it does not overburden the healthcare system. In this work we implement a forecast of the demand for hospital beds for the next 30 days for every state in Brazil for different scenarios and analyse how long it would take for the demand to exceed current available hospital beds.

OBJECTIVE

Carry out the projection of hospitalization by COVID-19 in Brazil, analysis occurring by states, following different policies of social distance in order to predict whether in a window of 30 days, overcrowding of hospital beds could occur.

METHODS

Local regression, data exploration.

RESULTS

Prediction of a 30-day window for overcrowding Hospital beds, in view of the adoption of public measures adopted in the first 30 days of fighting COVID-19, in the countries of: Germany, Italy and South Korea

CONCLUSIONS

By estimating the need for beds by Brazilian states, even adopting the best possible scenario with the population hospitalized for COVID-19 being discharged in a period of 10 days, in addition to the premise that all hospital beds (except for neonatal and pediatric) would be willing to receive the infected population, 5 states would collapse in the model adopted by South Korea, 16 Brazilian states would collapse on Germany models and all Brazilian states would collapse their health system based on the Italian model, in a 30 day time window. Therefore, it is recommended the adoption of public policies implemented by South Korea, in addition to increasing the number of beds with public policies with field hospitals (emergency beds for COVID-19).

It is noteworthy that in this scenario the Brazilian health system would make available for COVID-19 patients all available hospital beds, which would result in the said secondary deaths to COVID-19, people who need a bed to be hospitalized due to other diseases (heart attack, car accident, stroke, etc.), but because of the overcrowd of the public health system would return home, resulting in an end that could have been contoured if hospital treatment had been given to the pacient.

The objective of this study was to determine the thermodynamic and physical properties of beef strip loin steaks of varying thicknesses and USDA quality grades cooked with high and low grill surface temperatures. Thermal characteristics described by changes in the denaturation temperature (between 55°C – 60°C) and enthalpies of protein denaturation (70°C – 75°C) both differed (P = 0.031 and P = 0.001, respectively) among thick steaks, with thick steaks cooked on a high grill surface temperature having a lower denaturation temperature and enthalpy compared with thick steaks cooked on a low grill surface temperature. No differences (P > 0.05) were observed among thin steaks for denaturation temperature or enthalpy. The elastic behaviors of the surface and center of the steaks were analyzed to determine how the microstructure of the beef responded to applied stress. The elastic behavior of steak centers was influenced in a three-way interaction (P = 0.029) between quality grade, steak thickness, and grill surface temperature. The elastic behavior of the surface of steaks was influenced by the interaction of quality grade and steak thickness (P = 0.031). These interactions, along with the differences in the thermal characteristic of proteins, suggest that the microstructure of steaks was affected by each cooking treatment group. Hardness, resilience, and chewiness were each influenced by a three-way interaction (P = 0.023; 0.014; and 0.030; respectively). Thin steaks possessed greater cohesiveness (P = 0.038) and shear force ( P = 0.007) values. Meanwhile, thin steaks exhibited lower springiness (P = 0.002). The measured alterations in thermal and physical proper- ties in the beef steaks suggest that the composition, thickness, and cooking regiments impact the microstructure of beef, and this was ultimately confirmed through textural measurements. The results of this research can be used in the design of cooking processes that match beef characteristics.

A Note on Inferences About the Probability of Success
Authors: Wilcox Rand
Published: June 2020

There is an extensive literature dealing with inferences about the probability of success. A minor goal in this note is to point out when certain recommended methods can be unsatisfactory when the sample size is small. The main goal is to report results on the two-sample case. Extant results suggest using one of four methods. The results indicate when computing a 0.95 confidence interval, two of these methods can be more satisfactory when dealing with small sample sizes.

¿Se puede aún hablar de poder espiritual? (Primera parte)
Authors: Paláu Castaño Luis Alfonso
Published: June 2020

A menudo me quejo de que, de joven, nunca tuve maestros. Comentando indefinidamente, los profesores de filosofía repetían. Los antiguos retomaban a Platón, Descartes y Kant por una revolución llamada heroica y de izquierda, los nuevos se pusieron a plagiar a Marx, Nietzsche y Freud por otra, conservadora y de derecha. Se dice que los competidores de aquellos últimos citarán a Heidegger y Wittgenstein, la escuela continental de Europa versus la escuela analítica de Estados Unidos. Decepción perenne, no se dejaba de plagiar. Qué pensaba ese mundo por sí mismo; misterio. Lanzarse uno completamente solo cuesta un precio infinito.
Las tres vueltas al mundo. Michel Serres
Authors: Paláu Castaño Luis Alfonso
Published: June 2020

Cuando era joven, había decidido locamente que la vida del filósofo debía comenzar por tres necesidades imposibles, tres vueltas que había que cerrar. Antes de acceder a una sabiduría que consideraba lejana, yo creía al menos que el aprendiz debía, a guisa de preparación, darle la vuelta primero al mundo: visitar banquisa y el Pacífico, ver derivar icebergs y soplar las ballenas, atravesar los desiertos, izarse en lo alto de las cimas montañosas, no negarme ni los seísmos ni los volcanes, navegar a lo ancho, afrontar ciclones, explorar las islas y los continentes, en suma: hartar la dura belleza del planeta. Errar. Y en el extremo de la fatiga muscular del tiempo corto de la vida breve y del entusiasmo admirativo, nadie puede verlo todo. Quedaba la melancolía de ojear mapamundis.
Nuestro linaje totemista. Michel Serres
Authors: Paláu Castaño Luis Alfonso
Published: June 2020

Tenemos tres definiciones de totemismo. La primera, popular, pone en relación un hombre o un grupo con tal animal o tal planta, y en algunos casos con una cualidad. Por ejemplo, el cómic puede llamar a un indio “águila audaz”; la administración, absurda, llama “bisonte astuto” a un dispositivo vial. Confieso sin pudor que siendo adolescente los scouts me disfrazaron del tótem personal del zorro entusiasta; más bien, me hicieron el honor pues yo venero ese zorro y quiero a los dioses íntimos; pero yo detentaba también otro colectivo; aunque siendo Zorro, pertenecí por muchos años a la patrulla de los Tigres. Al menos se trataba, sin contradicción, de dos mamíferos cuadrúpedos carnívoros.
Reseña del libro A lomo de mula. Viaje al corazón de las FARC de Alfredo Molano
Authors: Cardona-Rodas Hilderman
Published: June 2020

Alfredo Molano escribe desde la polifonía de las experiencias de la guerra en Colombia. Cada uno de sus relatos explora, desde la subalternidad, las huellas de la violencia y el teatro de la crueldad y el dolor que ha significado el conflicto armado colombiano. Por ello, el libro A lomo de mula. Viaje al corazón de las Farc, publicado en 2016, es un vivo ejemplo del compromiso de la crítica en el acto político de la escritura. Molano, sociólogo y periodista, relata en su libro las condiciones de posibilidad y existencia del nacimiento del movimiento guerrillero Farc.

La noción de “creencia” y su manifestación en el uso o vigencia. Hacia una fenomenología del mundo social en José Ortega y Gasset
Authors: Quiroz Ospina Daniel Esteban
Published: June 2020

En este artículo se busca dar cuenta de una reflexión fundamental en la filosofía de José Ortega y Gasset. A partir de una crítica al punto de vista moderno, representado en este caso por Husserl, Ortega postula su idea de la vida humana como realidad radical. El análisis de la “presencia” de la vida conlleva al problema de la correlación ser humano-mundo en tanto pregunta por cómo se desenvuelve el yo en la circunstancia. Ortega responde a esta cuestión desde la noción de “creencia”, la cual es analizada aquí como punto central para pasar al tema fundamental: la fenomenología del mundo social, la cual está enmarcada en los conceptos de “uso” y “vigencia”. Así, este trabajo quiere dar cuenta de un camino fenomenológico que va de lo abstracto a lo concreto, desde la “presencia” de la vida hasta la existencia de la sociedad en tanto circunstancia fundamental de toda vida humana.

An overview of sex reassignment surgery
Authors: Olegário Raphael Lopes , Vitorino Silvia Maria Aparecida
Published: June 2020

Transexualidade é um subconjunto dos transgêneros, mas algumas pessoas transexuais rejeitam o rótulo de transgêneras. Um diagnóstico médico de disforia de gênero pode ser feito se uma pessoa expressar um desejo de viver e ser aceita como um membro de seu sexo identificado e se uma pessoa experimenta funcionamento prejudicado ou angústia como resultado de sua identidade de gênero. A variedade de cirurgias indicadas difere entre mulheres e homens trans. Para as mulheres trans, a reconstrução genital geralmente envolve a construção cirúrgica de uma vagina. Para homens trans, a reconstrução genital pode envolver a construção de um pênis através de faloplastia ou metoidioplastia.

Published: June 2020

Aspects of biology of Acerophagus papayae Noyes & Schauff (Hymenoptera: Encyrtidae), parasitoid of papaya mealybug. Acerophagus papayae Noyes & Schauff (Hymenoptera: Encyrtidae) is an important parasitoid of the papaya mealybug, Paracoccus marginatus Williams & Granara de Willink (Hemiptera: Pseudococcidae). The study was conducted with the objective to determine various aspects of the biology of A. papayae which include the effect of diet on adult longevity, fecundity and progeny, host stage susceptibility and preference, the effect of host stages on immature development, body size, and sex ratio of progenies.  Effects of diet on adult longevity was done in the absence of hosts. Fecundity was measured by the number of mealybugs parasitized. Host stage susceptibility and preference were carried out by exposing 2nd  and 3rd  nymphal instars and pre-reproductive adults of mealybugs to parasitoids. Results showed adult parasitoids fed with 10% honey solution lived almost fourfold longer than those provided only water. A. papayae parasitized 30.1±4.92 mealybugs, with a range of 13-60 mealybugs, during 5.8 days of adult life.  In no-choice (susceptibility) and paired-choice (preference) tests, the percentage of parasitized hosts were significantly greater in 2nd and 3rd instar nymphs than in adults. The mean immature developmental time of A. papayae was longer when the parasitoids develop in large host. Developmental time of male parasitoids was shorter than the females. Female wasps which emerged from hosts parasitized at the 3rd instar nymphs and adults were significantly larger than those from the 2nd instar nymphs.  Sex ratios of the offspring emerged from hosts that were parasitized as 2nd instars were strongly male-biased, while the later stages yielded more females than males.

Published: June 2020

Decrease in production and quality of grain due to neck blast disease in some lowland rice varieties. Neck blast disease of rice causes a decrease in yields both in quantity and quality. The study was conducted to see the effect of neck blast disease on the characteristics of grain and yields of several high yielding varieties of lowland rice. The varieties used were Ciherang, Inpari 4, Inpari 7, Inpari 8, and Inpari 9. The parameters observed were the incidence and severity of neck blast disease, the ratio of the size of the seeds of healthy and sick panicles and the estimated production. The analysis showed that all varieties planted were infected by neck blast disease, but based on Disease Incident rate in the Necks, Ciherang and Inpari 8 varieties reacted susceptible to neck blast disease, Inpari 7 and 9 were moderate and Inpari 4 was resistant to neck blast disease.  The quality of panicle grain infected by neck blast disease has decreased the size of grain width and was significantly different from grain of healthy panicles in all varieties. The highest estimated productivity was Inpari 4 variety of 10,378 kg/ha which experienced a decrease in production by 35.86% and the lowest was Ciherang variety of 8,367 kg/ha which experienced a decrease in production by 48.37% when they were infected by neck blast disease.

Published: June 2020

Eucalyptus (Eucalyptus spp.) is a fast-growing tree native in Australia, Papua, and Eastern part of Indonesia. It is valued for its timber, oil, gum, and resin, and as an ornamental tree. Many eucalyptus clones have been developed and planted for timber production in Sumatera. Several galls caused by insects are known as serious pests of eucalyptus and can reduce the quality and quantity of the timber production. This study was aimed to identify the gall inducers and describe the galls that formed on the eucalyptus clones which planted in Mt. Mutis, East Nusa Tenggara Province. The research was conducted from October 2017 to July 2018. A total of 855 seedlings consisting of 57 clones and 15 plants for each clone were planted in Mt. Mutis. Observations of the gall symptoms were done biweekly on each plant. Gall symptoms were directly observed and identified, included the form, size, location, color, and insect that caused the gall. There were four types of gall forms were recorded. One type of gall caused by Ophelimus sp. (Hymenoptera: Eulophidae) which similar to the gall recorded in Sumatera and Java. The other three gall forms were never been reported in Indonesia. The insects that associated with galls were Hymenoptera and Diptera orders. The type of gall that mostly found in the eucalyptus clones was the big clustered leaf gall caused by Fergusonina sp. (Diptera:  Fergusoninidae).  There are only two clones which are included as susceptible clones based on the type of gall formed, C35 and C53. There were 27 eucalyptus clones with no gall infestations which were considered as the good candidate of resistance eucalyptus clones to the gall infestations.

Authors: MÃ¼ller Antonio Jose
Published: June 2020

In many countries around the world, school is considered an essential factor for the development of children, young people, citizens and the country as a whole. However, in developing countries such as Brazil, the number of dropouts is very high. Many issues contribute to this reality: from student malnutrition and persistent social stratification to inadequate links between the school and the students' outside environment. Sport is a cultural expression that most people appreciate and it could best be used as a motivating tool for keeping students in schools. From this, this research aims to understand how sport can play its role in the effective contribution of promoting social inclusion and academic motivation. Participated in the exploratory qualitative study 14 male and female students from two schools, one public and one private, high school, through the use of structured interviews seeking to identify how the sport was established in relation to academic motivation and social inclusion in lives of these students.

The progress of labour at active phase I is the most tiring, continuous, and most mothers begin to feel the pain. During this time many of the efforts to streamline the uterine contractions among other things with the touch of a massage. Massage on the abdomen (effleurage) is a form of stimulation of the skin which is used during the process of childbirth can induce a relaxing effect. The purpose of the study is to know the influence of massage effect against uterine contractions in parturients active phase I.Quasi-experimental research draft with the design of the pretest-posttest with a control group. The sample was used for each group of 37 respondents with a purposive sampling technique. The results of the research there is a difference in the duration of uterine contraction before and after the intervention done by p <0.05, and the duration of the contractions of the uterus in the intervention group longer 10.270 seconds in the control group of 2,297 seconds. Effleurage massage has a significant influence on the duration of uterine contraction on at parturient active phase I.

Published: June 2020

Background and Objective: Wood is a hard, fibrous tissue found in many trees. It has been used for hundreds of thousands of years for fuel, construction and industrial raw materials. Â Ziziphus mauritiana is a tropical fruit tree species, belonging to the family Rhamnaceae, the specie is abundant in Sudano-sahelion region of Nigeria and it has been reported to have several medicinal uses from the leaves, stem andÂ  roots,Â  butÂ  technicalÂ  information on theÂ  useÂ  of the wood for construction purposes is limited. Therefore, determinations of selected physical and microscopic description of the wood of Z. mauritiana as a potential wood material for timber were investigated.Â Materials and Methods: Three matured trees of Z. mauritiana were felled from a research plantation of the Department of Forestry and Wildlife within the University of Maiduguri, in the North-eastern part of Nigeria and cross-cut into billets at the base, middle and top of the stems with estimated age of 7, 6 and 6 years old accordingly from the three sampled trees. Discs were obtained from each billet for determination of Physical properties (Bark, Bast, Sapwood, heartwood and pith proportion, Moisture content (MC), Density and some microscopic description (fibre and parenchyma cells) were all determined.Â Results: The average wood density of the sampled trees stood at 0.55Â±0.01g/cm3 and decreased from base to top. Similarly, moisture content decreased from 75.66Â±3.83% at the base to 54.08Â±1.19% at the top of the sampling height. The volumetric shrinkage is the total shrinkage in wood volume and it amounted to 10.11Â±3.17%. Averagely, bast accounted for 3.56Â±0.70%, 6.50Â±0.89%, 69.38Â±0.50 %, 16.00Â±3.23% and 10.38Â±1.96 % for bark, sapwood, heartwood and pith proportions respectively across the stem.Â Â Conclusion: The wood of Z. mauritiana is heavy. Within tree, wood density decreased from the base to the top. The range of values obtained in this study fall within the range of 450-750 kg/m-3 for species suitable for furniture, sheeting and lining, parquet, veneer wood for peeling and slicing with large vessel size and parenchyma cells. The range of values of volumetric shrinkage along the height and radial position shows that the wood is dimensionally stable. This was evident in the low tangentialâ€“radial shrinkage ratios recorded. Thus, indicating a low risk of deformation in wood during seasoning.Â
Resentimiento y Apocalipsis. La crítica de Nietzsche a las visiones del fin de los tiempos
Authors: Volker Gerhardt
Published: June 2020

Mediante el enlace copulativo entre Resentimiento y Apocalipsis se anuncia la construcción de un puente conceptual gracias al cual se proporciona una vía de paso segura hacia el abrupto complejo del Apocalipsis; mientras que, al mismo tiempo, se ﬁ jan unas estables bases para la posterior ubicación del escurridizo concepto dentro del pensamiento nietzscheano. Las pesquisas genealógicas localizan el origen del enfrentamiento en dos sistemas de valores diametralmente opuestos: Roma y Judea. Dos claves arquitectónicas soportan el peso de este apocalíptico constructo: Juan el evangelista y Jesús el hebreo.
«Ecrasez l'infâme» Cristianismo e historia de Occidente en Nietzsche
Authors: Esteban Enguita José Emilio
Published: June 2020

El objetivo de este artículo es analizar la relación entre el cristianismo y la historia occidental en la obra de Nietzsche. Desde Así habló Zaratustra en adelante, el cristianismo es el acontecimiento determinante y crucial para entender el sentido de la historia occidental. El nihilismo europeo se maniﬁesta bajo la forma del cristianismo y éste es el actor que representa el papel del ideal ascético en Occidente.
Nietzsche contra Pablo
Authors: Vitiello Vincenzo
Published: June 2020

Este artículo trata de la diferencia entra la Palabra de Jesús y la interpretación dada de ella de Pablo. Nietzsche convencido de esa diferencia contrapone el ascetismo débil –’budista’– de Jesús al áspero ascetismo de Pablo, verdadero fundador del cristianismo histórico. Partiendo de esta contraposición el artículo se concentra en la deﬁ nición nietzscheana del ‘ascetismo’ dada en la Genealogía de la moral y en su aplicación en El Anticristo. A través del análisis de algunos textos paulinos y evangélicos se llega a una ‘lectura’ diversa de la diferencia entre la ‘práctica’ de vida de Jesús y la ‘teología’ de Pablo. Una lectura muy cercana a la inquietante pregunta de María Zambrano con la que se abre el artículo: ¿Lo que ha realizado Europa con su religión ha sido cristianismo?
El espíritu libre o la ligereza creadora
Authors: Cano Virginia Mabel
Published: June 2020

El trabajo analiza la ﬁgura nietzscheana del espíritu libre como una clave para pensar de manera conjunta la crítica y la creación. En este sentido, la libertad de espíritu conjuga una tarea deconstructiva respecto de los sentidos heredados con una labor aﬁrmativo de conﬁguración de nuevas perspectivas. La fuerza plástica, propia de los espíritus libres, se desarrolla en este entramado de eliminación, selección y recreación de las signiﬁ caciones, entramado que se constituye en este juego del ‘no’ y el ‘sí’.
Nietzsche después de Schopenhauer
Authors: Giametta Sossio
Published: June 2020

El artículo trata de dar una respuesta al problema de la relación Nietzsche- Schopenhauer. Nietzsche, que fue ante todo un ‘moralista’, opone su escepticismo y su idea de individuo a la metafísica de Schopenhauer. Aunque hay simetría en la elección y en el planteamiento de los temas, hay importantes diferencias. Nietzsche hace de los dos mundos –fenómeno y noúmeno– un solo mundo, pero en el sentido del escepticismo y de la negación. En Schopenhauer, al contrario, la uniﬁcación se da en el sentido de la aﬁrmación
Физико-климатическая стойкость пенобетонов на основе техногенного сырья

Представлены результаты экспериментальной оценки параметров физико-климатической стойкости цементных пенобетонов. В экспериментах оценивались показатели и комплекс физико-технических свойств (как функция) влажностного состояния. В исследованиях использованы стандартные методики испытаний свойств. Установлено, что неавтоклавные цементные пенобетоны на основе неорганических техногенных наполнителей характеризуются показателями водостойкости, влажностной усадки, морозостойкости, теплопроводности на уровне нормативных требований к ячеистым бетонам соответствующей плотности. Поэтому можно прогнозировать, что их физико-климатическая стойкость соответствует требованиям, необходимым для эксплуатации в ограждающих конструкциях. Показано, что для повышения физико-климатической стойкости цементных пенобетонов требуется, чтобы параметры состава и структуры обеспечивали их возможно меньшую восприимчивость к влажностным воздействиям. К таким приоритетным параметрам следует отнести дисперсность и смачиваемость поверхности наполнителей, а также структуру пористости пенобетонов, определяемую и характеристиками наполнителей, и водотвердым отношением в пенобетонной смеси.
Results of the experimental assessment of physical and climatic resistance of cement
foam concretes are presented. Basic parameters of moisture and a complex of physical and technical
properties of foam concrete as a function of its moist state were evaluated. The standard methods
were used for testing the concrete properties. It has been found that the non-autoclaved cement
foam concrete based on non-organic waste fine aggregates meet the standard requirements to water
resistance, shrinkage, frost resistance, and thermal conductivity at levels meeting the standard requirement to foam concretes of the respective density. Therefore, it can be predicted that their climatic resistance meets the mandatory requirements for materials to be used for enclosing structures.
It has been established that in order to increase the climatic resistance of the cement foam concretes,
their composition and structural parameters should ensure least susceptibility to moisture influences. Such prioritized parameters should include dispersion and wettability of the fine aggregates
surface, and the porosity structure of the foam concrete, which is determined by the characteristics
of the fine aggregate and the B/T-ratio in the foam concrete mixture.

Published: June 2020

В составе судостроительного комплекса «Звезда» в г. Большой Камень имеется транспортно-передаточный док «Вымпел» грузоподъемностью 40000 т, предназначенный для спуска на воду с горизонтального стапеля крупнотоннажных судов и элементов морских платформ. Он построен в КНР и является крупнейшим в России доком такого типа, опыта эксплуатации таких сооружений в стране практически нет. Ввиду больших размеров, отсутствия непрерывных по всей длине башен док обладает значительной гибкостью, которая может оказывать существенное влияние на напряженно-деформированное состояние системы док–судно при проведении доковой операции. Док является безопорным, что приводит к дополнительным сложностям. В работе рассматриваются некоторые вопросы статики, динамики и прочности дока при спуске на воду крупнотоннажного танкера. Использовались традиционные методы теории и строительной механики корабля, а также трехмерное моделирование конструкции дока. Показано, что вследствие большой гибкости применение этих методов при оценке поведения дока может привести к неточным результатам. Рассмотрены также некоторые вопросы, связанные с технологией проведения доковой операции. Для повышения безопасности выполнения доковых операций в дальнейшем желательно проведение экспериментальных (натурных) исследований.

As a part of Zvezda Shipbuilding Complex in the town of Bolshoi Kamen there is floating transfer
dock Vympel with cargo capacity of 40,000 tons, purposed for putting afloat large-sized marine vessels and
elements of drilling platforms from a slipway. It was built in China, and is the largest dock of this kind in
Russia; any in-service experience of such facilities in our country is practically absent. In the view of its
large size and absence of continuous beams along its entire length, this dock is of a considerable flexibility
which can significantly affect the stress-strain state of dock-vessel system during dock operations. The fact
that this dock is unsupported leads to additional complexities. The paper deals with some issues of statics,
dynamics and strength of the dock when putting afloat a supertanker-type vessel. Traditional methods of theoretical and structural engineering of maritime vessels and three-dimensional modeling of the dock structure
were used. It is evident that due to increased flexibility of the dock application of these methods in evaluation of dock behavior can result in inaccurate results. Some issues relevant to the technology of carrying out
docking operations are considered as well. In order to improve safety of docking operations further experimental (full-scale) studies are desirable

Published: June 2020

Чтобы избежать частых повреждений фальшбортов на построенных в разных странах судах с различными вариантами конструктивного оформления, необходим системный анализ взаимосвязи принимаемых решений на различных этапах жизненного цикла судна. Авторы данной статьи представляют модельный эксперимент, позволяющий получить форму упругой линии стойки фальшборта при действии сдвигающего усилия. Выявлено влияние варьирования размеров стойки, допускаемого нормативными документами, на податливость фальшборта в продольном направлении. Построена серия графиков, характеризующих податливость в зависимости от его конструктивного оформления. Результаты данной работы можно использовать при проектировании и эксплуатации судов

In order to avoid frequent damage to bulwarks on vessels built in different countries with
different design options, a systematic analysis of interrelations of design solutions at different stages
of the vessel’s life cycle is required. The authors of this article present a model experiment that allows to obtain the shape of the elastic line of the bulwark stanchion under the influence of the shear
force. The effect of varying the dimensions of the stanchion permitted in compliance with the existing regulatory documents, on the bulwark flexibility in the longitudinal direction, has been determined. The series of diagrams characterizing the bulwark flexibility, depending on its design, have
been built. The results of this work can be used in design and operation of vessels.
Оценка воздействия твердой компоненты газовых выбросов судовых энергетических установок на окружающую среду портового города
Authors: HIEN TO TRONG
Published: June 2020

Возрастающий объем крупнотоннажных грузов, перевозимых судовым транспортом, в портовых регионах приводит к повышенной антропогенной нагрузке, связанной с загрязнением атмосферного воздуха отработанными газами, испускаемыми при работе судовых силовых энергетических установок. В статье рассматривается один из методов оценки антропогенного влияния эксплуатации таких установок на окружающую среду города Владивостока. Измерение массовой концентрации твердых частиц (РМ) в атмосферном воздухе проводились в летний и зимний периоды в восьми точках города, выбранных из условий орографических характеристик местности. Дана оценка судовому трафику, собрана информация о количестве и типе судов. На основе полученных данных произведен расчет общего объема РМ за год. Полученные нами результаты показали, что концентрации PM, имеющих диаметр менее 2,5 мкм (PM2,5) и 10 мкм (PM10), варьировались в разных районах города в широком диапазоне. В пяти из восьми контрольных точек отбора проб воздуха массовая концентрация РМ зимой превышала концентрацию РМ летом примерно в 1,2–2,2 раза для PM2,5 и в 1,7–3,8 раз для PM10. Общая масса РМ, выбрасываемых в районе порта Владивосток, составляла 80,5 тонн/год для PM10 и 64,4 тонн/год для PM2,5 в 2019 г.
