Comparison of different size left-sided double-lumen tubes for thoracic surgery
Authors: Nguyen Raisa D , Kurnutala Lakshmi N , Tucci Michelle A , Hierlmeier Bryan J
Published: January 2021

Study Objective:

The aim of this study is to see if there are any clinical differences between using 35 F DLT for all patients versus using patient height regardless of gender to estimate appropriate DLT size.

Design:

Prospective randomized study.

Setting:

University Hospital.

Patients:

50 patients age ≤18 years, undergoing lung or esophageal surgery requiring OLV.

Interventions:

Patients randomized to two groups (group-35F, group –DLT based on height).

Measurements and Main Results:

Data collected include demographics, ASA status, airway assessment, number of intubation attempts, Cormack-Lehane grade, number of times DLT repositioned, incidence of sore throat, oxygen saturation at induction and oxygen saturation at 5 minutes and 10 minutes after OLV. There was no statistically significant difference in demographics, ASA classification, Mallampati score, number of intubation attempts, Cormack-Lehane grade, number of times DLT was repositioned, and incidence of sore throat. In height based DLT group the odds were higher for the incidence of sore throat in 37-41 F group. Oxygen saturation at induction, 5 minutes and 10 minutes after OLV are not statistically significant between the two groups. Conclusion: Our findings suggest that the majority of patients receive unnecessarily large DLTs for thoracic surgery, which not only makes intubation inherently more difficult but also increases their risk of postoperative sore throat.
Homonymous thinning on macular optical coherence tomography indicating retrograde trans-synaptic degeneration from occipital infarctions
Authors: Meyer Benjamin I. , Chen Benson S. , Biousse Valérie , Newman Nancy J.
Published: January 2021

Inner retinal thinning on optical coherence tomography (OCT) occurring through retrograde trans-synaptic degeneration is an increasingly recognized phenomenon, even in acquired retro-chiasmal brain lesions. We describe a man with stable visual field defects from multiple bilateral posterior circulation infarctions, who had ganglion cell complex (GCC) thinning on macular OCT that corresponded precisely with his visual field defects. In contrast to previous reports indicating that peripapillary retinal nerve fiber layer (RNFL) changes are important in detecting this phenomenon, the peripapillary RFNL thickness and the optic disc appearance of our patient were relatively unaffected. Our case contributes to the growing body of evidence that retrograde trans-synaptic degeneration can manifest as isolated macular OCT findings.

Authors: Emam A.S. , Mohamed Eid S.
Published: January 2021

Recently, the vehicle brake system equipped with anti-lock braking systems (ABS) is considered one of the most important effective safety systems. The importance of ABS, to get maintains the safety of vehicles on roads during emergency braking and it enables reliable stopping whilst maintaining the vehicle stability and ease steer-ability. Therefore, the aim of this research is to investigate the vehicle braking performance of controlled brake ABS that is designed with three types of controller and compares them, they are bang-bang, Proportional Integral Derivative (PID) and Fuzzy Logic Control (FLC) on rough dry and wet roads to control longitudinal slip. The main obstacles of controller design in automobile systems are concerned to high non-linearities of the mathematical model. 2DOF longitudinal quarter vehicle model with taking into account the rational motion of the tire is used to examine the braking performance. The tire-road interface model and braking system model are included in vehicle model. By reviewing the results, it was found that FLC method has an effective and better effect compared to two methods on the performance of brake system equipped with ABS system. It was found that vehicle stopping distance was reduced by 21.77m and 10.3m with dry and wet asphalt roads respectively compared to braking without ABS for fuzzy control at velocity 100 km/hr.

Published: January 2021

Research into gas flow motion as a transported phase and pollutant – particulate matter (PM) is of crucial importance, their changes in particular areas of the object require knowledge of improving the apparatus. A cyclone is considered one of the most popular devices due to the new modified multi-channel design that involves combined separation and filtration phenomena. The findings of an accurate numerical model provide an opportunity to verify long-term experimental studies. In addition, it is possible to determine the impact of the designed principal elements of the structure comprising secondary gas inlets, inner slits and the convex bottom on gas and PM motion through verification conducting experimental research. The study focuses on simulating the upgraded cyclone using the SST k-omega model. The research has been conducted under the specified gas flow conditions such as high temperature and relative humidity (aggressive) gas and presents the results of the physical model to compare with. To achieve greater computational accuracy, a digital model of the cyclone made of specific volumetric elements has been developed thus expanding the grid and stepping to form the boundary zone. As a result, numerical simulation results differ by no more than 12.8% compared to the experimental studies results.

Béo phì là một bệnh phức tạp, mãn tính do đó rất khó để nghiên cứu các vấn đề liên quan đến béo phì ở người trong thời gian dài. Vì vậy, một số mô hình béo phì do khẩu phần ăn ở động vật được xây dựng và phát triển đã cung cấp thông tin giá trị về sinh bệnh học và giải pháp điều trị bệnh béo phì. Trong nghiên cứu này, chúng tôi sử dụng chủng chuột Swiss albino được chia làm hai nhóm thử nghiệm và theo dõi trong 24 tuần: nhóm ăn chế độ ăn ít chất béo (CTL) và chế độ ăn giàu chất béo (HFD). Kết quả cho thấy, lượng calo hấp thu, cân nặng và tỉ lệ mỡ cơ thể của nhóm HFD cao hơn so với nhóm CTL. Vào tuần 16 của giai đoạn thử nghiệm, nhóm HFD cho thấy chỉ số cholesterol toàn phần, acid uric, ALT và AST cao hơn so với nhóm CTL và cho thấy có tình trạng gan nhiễm mỡ. Như vậy, mô hình chuột Swiss albino béo phì do khẩu phần ăn là chìa khóa quan trọng để nghiên cứu và phát triển các giải pháp ngăn ngừa và điều trị béo phì.
Deep learning of virtual-based aerial images: increasing the fidelity of serious games for live training
Authors: Reed Dean , Thomas Troyle , Reynolds Shane , Hurter Jonathan , Eifert Latika
Published: January 2021

The aim of rapidly reconstructing high-fidelity, Synthetic Natural Environments (SNEs) may benefit from a deep learning algorithm: this paper explores how deep learning on virtual, or synthetic, terrain assets of aerial imagery can support the process of quickly and effectively recreating lifelike SNEs for military training, including serious games. Namely, a deep learning algorithm was trained on small hills, or berms, from a SNE, derived from real-world geospatial data. In turn, the deep learning algorithm’s level of classification was tested. Then, assets learned (i.e., classified) from the deep learning were transferred to a game engine for reconstruction. Ultimately, results suggest that deep learning will support automated population of highfidelity SNEs. Additionally, we identify constraints and possible solutions when utilising the commercial game engine of Unity for dynamic terrain generation.

Authors: Mrazkova Duricova Lucia , Jašek Roman , Mrazek Jan , Hromada Martin
Published: January 2021

The soft targets and crowded places are closely related to the risk of attack to the group of people. These places are very specific because the moving in the soft targets is not organized. That’s mean these places have open and public access. The attack in the soft targets (attack on the soft targets) can have a significant impact on the population and life of the people. The main aim of the proposed software is to analyze the features of the object. According to the analyses, we can define the corrective action, which can have a significant impact on the security situation in the object.
Research on one-way channel conversion strategy of coastal ports based on system simulation
Authors: Guo Zijian , Xia Zicheng , Wang Wenyuan
Published: January 2021

The waterway is the necessary passage for ships to enter and leave the port. From the perspective of cost, many coastal port channels are one-way channels, it alternates as an inbound channel and an outbound channel. The oneway channel conversion strategy refers to when it is used as an inbound channel and when it is used as an outbound channel. By constructing a simulation model, this paper simulates the one-way channel conversion strategy that uses a fixed time period conversion, a conversion considering a certain number of outbound ships, and a conversion with the combination of time and number of outbound ships to achieve the best state of the port's overall operations. By comparing the port service level, traffic capacity of waterway, ships waiting time and other indicators, a one-way channel conversion strategy suitable for port operations is recommended.
Stochastic floating quay crane scheduling on offshore platforms: a simheuristic approach
Authors: Souravlias D. , Duinkerken M. B. , Morshuis S. , Schott D. L. , Negenborn R. R.
Published: January 2021

The scheduling of quay cranes is a core logistics challenge that affects significantly the loading and unloading time of a vessel berthed at a container terminal. In this paper, we study the Stochastic Floating Quay Crane Scheduling Problem involving cranes situated on the quay of an offshore modular platform. Specifically, we consider the case in which each crane is situated on a different module of the platform, thereby confining its operation range. Additionally, we assume stochastic crane productivity rates due to the effect of the offshore wind. To tackle the problem, we propose a simheuristic framework, which combines Iterated Local Search with Monte Carlo Sampling into a joint collaborative scheme. The main objective is to minimize the expected completion time of the loading and unloading process taking into account precedence, nonsimultaneity, non-crossing, and spatial constraints of the problem at hand. The performance of the proposed simheuristic is investigated on a set of established problem instances across different configuration parameters and under various real-world environmental scenarios offering insightful conclusions.

Validez diferencial en la evaluación del constructo frustración
Authors: Rodríguez Sobrino Noelia , García Medina Pablo
Published: January 2021

En este trabajo se presenta un estudio correlacional que describe la conexión existente entre diferentes estilos de respuesta a la frustración evocada. Para ello nos apoyamos en la Prueba de Respuestas a la Frustración (PRF) y el Cuestionario sobre Valores y Principios (V. y P.), ambos de García-Medina, P. La prueba PRF tiene la finalidad de identificar el constructo de agresividad como respuesta-rasgo. Los restantes estilos de respuesta aislados, según el autor, son el autopunitivo y el solucionador. Se propone para fines de validez diferencial así como de constructo un cuarto factor: frustración expresada. Se aplicó otro cuestionario (Valores y Principios) del que se extrajeron, mediante rotación varimax, dos factores cognitivo-actitudinales. Un primer factor denominado Actitud-disocial y otro segundo denominado Actitud-prosocial. Encontrándose utilidad y apoyo para el primero debido a que presenta validez diferencial significativa al correlacionarlo con los restantes constructos. Se dieron particularmente relaciones positivas entre el estilo de respuesta agresiva y frustración De otro lado, se hallaron relaciones negativas entre un estilo de respuesta de solución y frustración manifestada. La Actitud-disocial, correlaciona positivamente con las respuestas de estilo agresivo. Sin embargo, se obtuvieron relaciones negativas con la tendencia o estilo a dar respuestas de solución a los conflictos. Entendido como respaldo de validez diferencial. Finalmente, hemos de destacar que la actitud prosocial se relacionó de forma positiva con la respuesta autopunitiva en un subgrupo de casos que presentaban menor tolerancia a la frustración. En relación a las pruebas se deduce a partir de los resultados que el PRF se muestra más sensible que el cuestionario V y P basado en dos factores y esta sensibilidad es mayor en personas que puntúan bajo en el estilo de respuesta agresiva.

Published: January 2021

El presente estudio analiza la relación entre la percepción de inseguridad ciudadana, el miedo al delito, la ideología política y la frecuencia de victimización; en una muestra de habitantes de la ciudad de Lima. Como medidas de ideología política se utilizaron las escalas de autoritartismo de ala derecha (RWA) y de orientación hacia la dominancia social (SDO). Para la medición de la percepción de inseguridad ciudadana se desarrolló una escala ad hoc. Se encontró una correlación positiva entre el autoritarismo, la orientación hacia la dominancia social y la percepción de inseguridad ciudadana. Se encontró además, una correlación positiva entre el autoritarismo y la intensidad con la que se percibe el peligro. Los resultados sugieren que una mayor tendencia hacia el autoritarismo está asociada con la creencia de que la inseguridad y la delincuencia están vinculadas con los grupos de menor estatus social.
Violencia de género ocasional: Un análisis de las penas ejecutadas
Authors: Antón García Lorena , Larrauri Pijoan Elenea
Published: January 2021

En el año 2003 se han aprobado diversas leyes en materia de violencia doméstica que han supuesto la elevación a delito de las conductas de violencia ocasional y una agravación general de las penas en este ámbito. La investigación empírica que se ha llevado a cabo, relativa al maltrato ocasional en el ámbito de la pareja, pretende conocer cómo este aumento de penas ha sido aplicado por los jueces. Para ello, se ha realizado un análisis cuantitativo de las sentencias condenatorias por el delito mencionado y de los autos de ejecución correspondientes a cada una de esas sentencias, que ha servido para conocer cuándo los jueces optan por la pena de prisión y cuándo por el uso del trabajo en beneficio a la comunidad para el maltrato ocasional en la pareja; cuáles son las penas definitivas que efectivamente se cumplen; y cuál es el porcentaje de aplicación de las reglas de conducta, concretamente, la obligación de realizar programas formativos o de tratamiento como condición para la concesión de la suspensión de la pena de prisión.
Reintroduction of the European silver fir (Abies alba Mill.) in Białowieża Forest
Authors: Marozau Aleh
Published: January 2021

In 1996 and 1998, Professor A. Korczyk created a half-sib plantation of the European silver fir (Abies alba Mill.) in the Polish part of Białowieża Forest (Hajnówka Forest District, sub-district Wilczy Jar, subcompartments 416Ag and 416Сf). The planting was carried out in furrows at a spacing of 1.3 x 1m in three plots of 0.22 ha each in an area of fresh forest. To grow the seedlings, seeds from the “Tisovik” tract (in the Belarusian part of Białowieża Forest) were used. According to some researchers, the Abies alba in this tract has a natural origin and is a relic of Białowieża Forest. Given this circumstance, and also in connection with the mass drying-out of the Norway spruce (Picea abies (L.) Karst.), there is a practical interest in studying the growth of fir crops in this territory. The results of our studies (2018) indicated the very intensive growth of this species in 22-year-old cultures (subcompartment 416Ag, plot 1, 10 half-sib families). The trees showed no signs of disease or insect damage, the crowns were conical in shape and the shoots were densely covered with needles. The good state of the forest planting can be considered as evidence of soil hydrological conditions suitable for growth and meeting the A. alba’s ecological and biological needs, as well as confirmation of its autochthonous nature.

Authors: Abdizadeh Hadis , Southcott Jane , Gindidis Maria
Published: January 2021

Issues of language shift (LS) and language maintenance (LM) are inevitable consequences of globalization and increased mobility of human populations. This qualitative case study investigated attitudes of migrant parents from Iran towards Persian community language maintenance (CLM) for their school-age children in Australia. Ten parents residing in Melbourne, Victoria were interviewed in two groups and demographic data were collected. The participants were seven female and three male parents who had at least one school-age child. In this qualitative case study, data were analyzed thematically. Three major themes concerning Persian CLM were identified: parents’ attitudes, strategies adopted for maintenance, and challenges for their children. The parents believed that CLM supported cultural identity, preserved family cohesion, and fostered bilingualism, all of which were considered valuable future skills for their children. Interviewees adopted diverse strategies including the establishment of family language use policies, sending their children to Iranian community language school, frequent contacts with extended family in Iran, and the use of Persian media and literature. The influential role of siblings and peers in their children’s language shift, and a lack of age-appropriate Persian books and visual materials were the main challenges to CLM mentioned by the parents in this research.

Multiple paleoclimatic studies indicate that the Earth has warmed significantly since the end of the 19th century. The mean temperature of the Earth's surface is rising unnaturally and frighteningly fast, having a large impact and threatening the very near future of human civilization. This paper presents an analysis of the variability of air temperature in the Bucharest metropolitan area in the decade 2011-2020, related to the 1901-2000 period in the context of the global warming. The research includes the study of the mean annual and monthly temperature, the absolute maximum and minimum temperature, the frequency of the thermal character in the cold season and in the hot season and the frequency of days with characteristic temperatures. The 2011-2020 decade was the hottest one since the beginning of meteorological measurements. Related to the 1901-2000- reference period, the air temperature increased by 1.6°C, from 11.1°C to 12.7°C, the mean of the 10 years. The year 2020 was the hottest year, marking the end of the hottest decade since the meteorological measurements were made, the mean annual temperature being 13.5°C, by 2.4°C higher than the mean of the 1901-2010 reference period.

The Menghidupkan Kembali Spirit Politik Ilmu Pemerintahan
Authors: Mohamad Firdaus
Published: January 2021

Ilmu pemerintahan pada dasarnya adalah ilmu yang mempelajari ilmu politik, dimana dalam seberapa aspek dari ilmu pemerintahan seperti teori, metode dan metodologi tidak jauh berbeda dengan ilmu politik. Tulisan ini mencoba menjelaskan dan menjabarkan hubungan antara ilmu pemerintahan dengan ilmu politik. Sejauh ini ilmu pemerintahan hanya mempelajari birokrasi, administrasi publik, manajemen dan kebijakan publik. Dengan hanya dipamahi sebagai ilmu administrasi membuat ilmu pemerintahan hanya menjadi seperti ilmu perkantoran. Hal tersebut dikarenakan adanya warisan kolonial dan suburnya neoliberalisme. Untuk itu tulisan ini akan mencoba menghidupkan kembali roh ilmu politik ke dalam ilmu pemerintahan yang akan menjelaskan bahwasannya pada realitasnya aspek pemerintahan sangat dipengaruhi oleh aspek politik. Dan memberikan sebuah alternatif baru terhadap eksistensi ilmu pemerintahan yang berbasis untuk memuliakan rakyat.

The paper addresses the issues of qualitative improvement of information systems which support subsurface use, monitoring, and control of the Russian mineral base through the development of information technologies. Based on material processing, contained in the registration cards of geological studies, in which the main geological study data are summarized, a model of an interactive study map is proposed. The proposed interactive map of verified materials provides a great opportunity for creating a catalog of works, as well as compiling specialized maps and cartograms to reflect the geological study of any given territory.
Social effect of Covid-19: Estimates and alternatives for Latin America and the Caribbean

This document offers estimates of the possible changes in the social structure of the countries of Latin America derived from the consequent economic contraction from the Covid-19 pandemic and explores the possible costs and benefits of different types of interventions to cushion its impact. The analysis forecasts that the number of people living in poverty (extreme and moderate) would increase by up to 44 thousand million people in the region. It also finds that the policy with the highest benefit-cost ratio is the postponement of payroll taxes and social security contributions. Other alternatives such as granting support to unemployed persons, temporarily doubling the benefits of existing social programs, and the transfer of income to self-employed workers also generate a favorable benefit-cost ratio, with differences among countries.

DESIGN AND SIMULATION OF AN ON-GRID PHOTOVOLTAIC SYSTEM
Authors: IKOİWAK Ekom Abasi , BİG-ALABO Ameze , WOFURU İnnocent
Published: January 2021

ABSTRACT- In this paper, the design and simulation of an On-grid photovoltaic system for the faculty of Engineering, Abuja campus, University of Port Harcourt (Latitude: 4.78°S, Longitude: 7.01°E) was researched in-order to verify alternate power source possibility that can supplement for the inconsistent power from the (Power holding company of Nigeria) grid to the faculty. The system Solar modules are mounted in a fixed tilt orientation in 4-parallel strings of 15 Solar panels in series on the roof-top of the faculty. The photovoltaic system is also designed with a two - parallel string of nine Tesla Powerwall batteries in series for the battery bank storage system. Inverters used for this system are two 9.9kW battery-based grid-tied inverters stacked in parallel with an inbuilt Maximum power point tracker, MPPT. The reinjection system is on-grid as a net-meter is not used since the Power Holding Company of Nigeria, PHCN does not support Net- metering. Thus, power is not injected into the grid from the solar photovoltaic system. In solving the faculty’s power lapses and improving power supply quality in the faculty, data collected both within the faculty. These methods include data collection, evaluation of load data, data analysis, suitable design adoption, simulation of data. A solar photovoltaic software application package called PVsyst was employed for various simulations and plots. The end simulation and final work prove the system to be 57% efficient in performance.

La producción de conocimiento orientado a la política en Argentina: un análisis de centros de política, organismos internacionales y centros académico
Authors: Palamidessi Mariano , Gorostiaga Jorge , Aberbuj Claudia
Published: January 2021

Este artículo busca caracterizar el trabajo de un grupo de organizaciones que producen conocimiento para influir sobre el diseño de las políticas educativas en la Argentina. El análisis se basa en entrevistas a los responsables de las áreas de educación y en información extraída de las páginas web de tres centros de política, tres organismos internacionales y un centro académico, que se seleccionaron por su fuerte continuidad y presencia en la generación de este tipo de conocimiento desde comienzos de la década de 2000. Se describen y comparan los siete casos de acuerdo con cinco dimensiones: definición de la agenda de producción de conocimiento; financiamiento; conformación de los equipos de trabajo; estrategias de producción de conocimiento; y circulación del conocimiento.
Resiliencia e inteligencia emocional: conceptos complementarios para empoderar al estudiante
Authors: Belykh Anna
Published: January 2021

En este artículo se exponen brevemente los resultados de la fase hermenéutica del estado del arte correspondiente a la investigación doctoral “Inteligencia emocional para potenciar la resiliencia desde la educación superior”, enfocado en el análisis de dos conceptos psicológicos aparentemente independientes, pero íntimamente relacionados. Por un lado, el estudio de la resiliencia ha permitido descubrir las características del individuo, su contexto y procesos psico-sociales que facilitan un manejo exitoso de situaciones adversas o estresantes. Aplicada al ámbito educativo, desde sus dos perspectivas –estructural y procesual– esta línea vislumbra la esencia de cambio socioemocional en los actores educativos, aunque sus propuestas metodológicas suelen limitarse a predicar con el ejemplo y brindar afecto a los estudiantes. Por otro lado, la investigación de la inteligencia emocional que también estudia a las personas exitosas desde sus rasgos de carácter o capacidades de racionalización emocional ofrece un complemento metodológico basado en los procesos cognitivos que estructura una posible acción de educación para potenciar, entre otras, las cualidades preconizadas por los investigadores de la resiliencia. La vinculación de estas perspectivas ofrece un marco de referencia para el diagnóstico e intervención educativa que fomente un mayor empoderamiento del estudiante universitario desde el aula.

The purpose of this study was to review the effect of slide board training in beginner rowing athletes on aerobic capacity. Our study consists of 18 beginner rowing athletes in Galatasaray Club in the sub-elite category whose age mean were 14.94±,96years, height mean were 180.35±3.95cm, and weight mean were 70.24±6.94kg. The first group (Slide Board Group n=9) in working group was performing slide board while the second group (Control Group, n=9) was performing classical preparation training. The rowing ergometer was used for MaxVO2 measurement at the beginning and end of the preparation training. The standard deviation (SD) and arithmetic mean (AM) were utilized to analyze the data as the descriptive statistics. Wilcoxon test was used for compared the pre and post-test of two groups; Mann−Whitney U test specified the difference between two groups. As a result of the research, a significant difference was found in the I. Group (SBG) pre-test and post-test results (P

As in many other countries in the world, the pandemic has exerted a
heavy toll on Morocco’s population. Its economy has also been hit by a severe drought
that affected agriculture output. The authorities’ prompt response has helped contain
the social and economic damage from the shocks but could not avoid a severe
contraction of GDP. The loss of tax revenues deteriorated the fiscal position, while the
fall in tourism receipts widened the current account deficit. However, greater access to
external borrowing, including the full drawing of the IMF Precautionary and Liquidity
Line (PLL) arrangement, has helped maintain international reserves at adequate levels
so far in 2020. A gradual economic recovery is expected to begin in 2021, assuming the
impact of the drought and the health crisis wane next year. The recent rise in COVID-19
cases, both in Morocco and its main trading partners, suggests that this outlook
remains subject to significant downside risks.
