Authors: Kawamoto Eiji , Ito-Masui Asami , Esumi Ryo , Ito Mami , Mizutani Noriko , Hayashi Tomoyo , Imai Hiroshi , Shimaoka Motomu
Published: December 2020

Background

Use of wearable sensor technology for studying human teamwork behavior is expected to generate a better understanding of the interprofessional interactions between health care professionals.

Objective

We used wearable sociometric sensor badges to study how intensive care unit (ICU) health care professionals interact and are socially connected.

Methods

We studied the face-to-face interaction data of 76 healthcare professionals in the ICU at Mie University Hospital collected over 4 weeks via wearable sensors.

Results

We detail the spatiotemporal distributions of staff members’ inter- and intraprofessional active face-to-face interactions, thereby generating a comprehensive visualization of who met whom, when, where, and for how long in the ICU. Social network analysis of these active interactions, concomitant with centrality measurements, revealed that nurses constitute the core members of the network, while doctors remain in the periphery.

Conclusions

Our social network analysis using the comprehensive ICU interaction data obtained by wearable sensors has revealed the leading roles played by nurses within the professional communication network.
Examining a Digital Health Approach for Advancing Schizophrenia Illness Self-Management and Provider Engagement: Protocol for a Feasibility Trial
Authors: Kidd Sean , McKenzie Kwame , Wang Wei , Agrawal Sacha , Voineskos Aristotle
Published: December 2020

Background

In schizophrenia spectrum populations, adherence to treatment is poor, community-based supports are limited, and efforts to foster illness self-management have had limited success. These challenges contribute to frequent, lengthy, and costly hospital readmissions and poor functional outcomes. Digital health strategies, in turn, hold considerable promise in the effort to address these problems.

Objective

This feasibility trial will examine a digital health platform called App4Independence (A4i), which was designed to enhance illness self-management and treatment engagement for individuals with schizophrenia.

Methods

Feasibility metrics in this single-blind, randomized trial include study recruitment and retention, rate of technology use, safety, and utility in clinical interactions. Other outcome metrics include symptomatology, treatment adherence, patient-provider alliance, and quality of life. In this trial, 160 study participants with schizophrenia spectrum diagnoses will be randomized to either treatment or control conditions, with pretest-posttest outcomes measured over a 6-month period.

Results

This study was funded by the Canadian Institutes of Health Research in January 2020 and received Institutional Review Board approval on August 13, 2020. This study plans to begin recruiting in January 2021 and will be completed within 3 years. Data collection is projected to begin in January 2021.

Conclusions

This research will provide critical information for the development of this new technology in the larger effort to address a key problem in the schizophrenia field—how to leverage technology to enhance illness self-management and care engagement in resource-limited service contexts.

Transportation and Change through an Anthropological Lens
Authors: Clarke Mari H.
Published: December 2020

This paper provides a broad overview of anthropological research on roads and transport as a prelude and context for the other papers in this themed issue. The paper begins with a short historical overview of anthropological approaches to roads and transportation. Then it offers a case study on how roads both facilitated and reflected major socio-economic changes in Methana, Greece, reflecting change in the broader context of Greece society. Next, it describes applied social analysis approaches to the design of roads that emerged from the World Bank and related organizations. Finally, it explores the current flowering of anthropological research on roads, which encompasses technopolitical, political ecology, spatial, and semiotic analyses.  A second case study describes efforts to build a “culture” of inclusive road stewardship through a World Bank financed rural roads project in Vietnam. The paper concludes by reflecting on possible future directions for transport anthropology, which offers strategic opportunities to influence large infrastructure investments, transport policy, and anthropological theory.

Fatigue Reliability Analysis of Tunnelling Boring Machine Cutterhead with Cracks
Authors: li jie , zhang bin , liu chuang , guo jingbo
Published: December 2020

The cutterhead of tunnel boring machine is a large-scale metal welding
structure, which is prone to problems such as wear and cracking during
the tunnelling process. For the issue, the fatigue crack propagation
rate model of cutterhead under different reliability was established,
based on the damage tolerance of cutterhead. Its dangerous position of
cutterhead failure was determined by using finite element method.
According to the fatigue load spectrum, the fatigue propagation life of
cutterhead under different reliability was calculated, the main factors
affecting the reliability of cutterhead were analyzed and the
engineering experiment is carried out. The results show that three
dangerous positions of the cutterhead failure are the junction of the
split plane, the maximum deformation of the block and the central cutter
seat. The load stress amplitude and initial crack size are the main
factors affecting the crack propagation life and the reliability of
cutterhead. With the increase of load stress amplitude and initial crack
size of cutterhead, the fatigue crack propagation life of cutterhead
decreases and the reliability is worse. When the initial crack size of
cutterhead is greater than 0.5mm, the fatigue crack propagation life of
cutterhead decreases obviously. The research results provide a
scientific basis for crack detection, life prediction and reliability
evaluation of cutterhead structure.
Larger body size leads to greater female beluga fitness at the southern periphery of their range
Authors: Ferguson Steven , Yurkowski David , Hudson Justine , Edkins Tera , Willing Cornelia , Watt Cortney
Published: December 2020

Identifying phenotypic characteristics of evolutionarily fit individuals
provides important insight into the evolutionary processes that cause
range shifts with climate warming. Female beluga whales (Delphinapterus
leucas) from the Canadian high Arctic (BB) residing in the core region
of the species’ geographic range are 14% larger than their conspecifics
at the southern periphery in Hudson Bay (HB). We investigated the causal
mechanism for this north (core)-south (periphery) difference as it
relates to fitness by combining morphometric data with ovarian corpora
counted in female reproductive tracts. We found evidence for
reproductive senescence in older HB females from the southern peripheral
population but not for BB whales. Female beluga whale fitness in the
more-northern BB increased faster with age (48% partial variation
explained) versus a more gradual slope (25%) in HB. In contrast, body
length in HB female beluga accounted for five times more of the total
variation in fitness compared to BB whales. We speculate that female HB
beluga fitness was more strongly linked with body length due to higher
density, as larger body size provides survival advantages during
seasonal food limitations. Understanding the evolutionary mechanism of
how fitness changes will assist conservation efforts in anticipating and
mitigating future challenges to peripheral populations.
The Role of Conservative Management in Treatment of Critical Limb Ischemia
Authors: Mohamed Sara , Dermott Deirdre C Mc , Ahmed Khalid , McInerney Veronica , Howard Linda , Tubassam Muhammad , O'Brien Timothy , WALSH STEWART
Published: December 2020

Background: Revascularization has been considered the gold standard
treatment for critical limb ischemia (CLI). Due to the high morbidity
and mortality associated with intervention, evidence has emerged
recently supporting the suitability of conservative management as a
primary option to achieve amputation-free survival (AFS) in CLI patients
even when revascularization is technically feasible. Methods: A
prospective database of CLI patients was developed during pre-screening
of patients for a phase 1 stem cell therapy clinical trial. The overall
survival (OS) and AFS rates for patients treated with revascularization
were compared to those treated conservatively. Statistical significance
was set as p value < 0.05. OS and AFS for the two groups were
estimated by Kaplan-Meier survival curves. Results: Patients in the
conservative group were more likely to have Rutherford Class 5 and be
diabetic while they were less likely to be active smokers or have
hyperlipidemia (Table 1). There were no significant differences between
the two groups in mortality, amputation, overall AFS or one-year AFS
rates. Kaplan-Meier cumulative OS and AFS over the 3 years follow-up
period of the study demonstrated significant differences between the
conservative and revascularization groups (Log Rank: 0.031 & 0.045;
respectively). This statistical significance was not detected when
one-year AFS was evaluated (Log Rank 0.096). Conclusion: Conservative
management can be a suitable management option to achieve one-year AFS
for some CLI patients. Further studies are needed to identify robust
clinical criteria for identifying patients who will benefit from
conservative management.
An ultrasound study of the prevalence of endometriosis in women attending for early pregnancy assessment: a prospective observational study
Authors: Bean Elisabeth , Naflalin Joel , Horne Andrew , Saridogan Ertan , Cutner Alfred , Jurkovic Davor
Published: December 2020

Objective To assess the prevalence of endometriosis using pelvic
ultrasound examination in women attending for early pregnancy care
Design Prospective observational study. Setting A dedicated early
pregnancy unit. Population We included 1341 consecutive women who
attended for an early pregnancy assessment and had transvaginal
ultrasound scans performed by a single clinician. Methods In addition to
the presence of endometriosis on ultrasound scan, we collected data on
patient demographics and concurrent gynaecological conditions. Data
analysis was performed using logistic regression and multivariate
analysis. Main outcome measures The prevalence of endometriosis in
addition to possible associations with demographic and clinical
variables. Results The prevalence of endometriosis in women attending
the early pregnancy unit was 4.9% (95% CI 3.8 – 6.2); In 33/66 (50%,
95% CI 37.9 – 62.1) women with endometriosis, this was a new diagnosis
made for the first time during their early pregnancy scan. The presence
of endometriosis was strongly associated with congenital uterine
anomalies (p < 0.001; OR 5.69, 95% CI 2.17 – 14.9) and
uterine fibroids (p = 0.004; OR 2.37, 95% CI 1.31, 4.28). Conclusions
Endometriosis is present in nearly 5% of women attending for early
pregnancy assessment. In half of the women with endometriosis, the
diagnosis was made for the first time during pregnancy. We propose that
ultrasound may be a useful tool for the detection of endometriosis and
to identify pregnant women who may benefit from specialist antenatal
care. Funding No funding was obtained for this work. Keywords

Published: December 2020

Background and Purpose: Canthin-6-one (Cant) is an indole alkaloid found
in different medicinal plants, reported to be gastroprotective,
anti-inflammatory, anti-microbial, anti-diarrheal and
anti-proliferative. We aimed to explore Cant in the management of
ulcerative colitis (UC) using a trinitrobenzenesulfonic acid
(TNBS)-induced rat model. Experimental Approach: Cant (1, 5 and
25 mg/kg) was administered by oral gavage to Wistar rats followed by
induction of colitis with TNBS. Macroscopic and histopathological
scores, myeloperoxidase (MPO), malondialdehyde (MDA) and reduced
glutathione (GSH) were assessed in colon tissues. Pro- (TNF-α, IL-1β and
IL-12p70) and anti-inflammatory (IL-10) cytokines, and vascular
endothelial growth factor (VEGF) were also quantified. Mitogen-activated
protein kinase 14 (MAPK14) and Toll-like receptor-8 (TLR8), as putative
targets, were considered through in silico analysis. Key Results: Cant
(5 and 25 mg/kg) reduced macroscopic and histological colon damage
scores in TNBS-treated rats. MPO and MDA were reduced by up to 61.69%
and 92.45%, respectively, compared to TNBS-treated rats alone.
Glutathione concentration was reduced in rats administered with TNBS
alone (50.00% of sham group), being restored to 72.73% (of sham group)
under Cant treatment. TNF-α, IL-1β, IL-12p70 and VEGF were reduced, and
anti-inflammatory IL-10 was increased following Cant administration
compared to rats administered TNBS alone. Docking ligation results for
MAPK14 (p38α) and TLR8 with Cant, confirmed that these proteins are
feasible putative targets. Conclusions and Implications: Cant has an
anti-inflammatory effect in the intestine by down-regulating immune
molecular mediators and decreasing oxidative stress. Therefore, Cant
could have therapeutic potential for the treatment of inflammatory bowel
disease and related syndromes.
Phytochemicals targeting metabolic reprogramming in cancer: an assessment of role, mechanisms, pathways and therapeutic relevance

Published: December 2020

The metabolism of cancer is remarkably different from that of normal
cells and confers variety of benefits including the promotion of other
cancer hallmarks. As the rewired metabolism is a near-universal property
of cancer cells, efforts are underway to exploit metabolic
vulnerabilities for therapeutic benefit. In the continued search for a
safer and effective ways of cancer treatment, structurally diverse
plant-based compounds have gained substantial attention. Here, we
present an extensive assessment of the role of phytocompounds in
modulating cancer metabolism and make a case for the use of plant-based
compounds in targeting metabolic vulnerabilities of cancer. We discuss
the interactions of phytocompounds with major metabolic pathways and
evaluate the role of phytochemicals in the regulation of growth
signaling and transcriptional programs involved in metabolic
transformation of cancer. Lastly, we examine the potential of these
compounds in clinical management of cancer along with limitations and
challenges
Celastrol alleviates comorbid obesity and depression by directly binding amygdala hnRNPA1 in a mouse model
Authors: Zhu Chunyan , Yang Jun , Zhu Yongping , Li Jiahao , Chi Hongyu , Tian Congmin , Meng Yuqing , Liu Yanqing , Wang Jigang , Lin Na
Published: December 2020

Background and Purpose: Obesity and depression are highly comorbid and
far from effective treating. Celastrol was reported useful for obesity,
but its role in the obesity-depression comorbidity remains unknown. This
study aims to investigate the efficacy and associated mechanism of
celastrol in this comorbidity. Experimental Approach: A comorbidity mice
model of obesity and depression were constructed. Bodyweight, adipose
tissue rate, blood glucose, and blood lipids were used to assess
obesity. Forced swimming test and tail suspension test were investigated
to evaluate depression. In microglial cells, direct targets of celastrol
were screened and determined by chemical proteomics, pull-down
experiment, and competitive binding assay. In the mice model, the target
gene’s mediating effect was investigated by stereotactic injection of
AAV9 virus. The expression level of target molecules was detected by
immunofluorescence. Key Results: Celastrol relieved the comorbid
symptoms, inhibited the mal-activated Neuropeptide Y, and activated the
mal-inhibited 5-HT neurons in the amygdala. The efficacy was associated
with the inhibition of the mal-activated microglia. Chemical proteomics,
pull-down experiment, and competitive binding assay results indicated
celastrol’s directly binding hnRNPA1. In the animal model,
downregulation of hnRNPA1 in the amygdala relived symptoms and NPY and
5-HT neurons’ changes. Meanwhile, overexpression of hnRNPA1 aggravated
the comorbidity and antagonized the effect of celastrol. Conclusion and
Implications: Celastrol alleviated comorbid obesity and depression in a
mouse model by directly binding hnRNPA1 in the amygdala. Celastrol may
become a potential drug, and hnRNPA1 in the amygdala could be a useful
target to combat the comorbidity.

Published: December 2020

This study was conducted at the experimental area of the Cukurova
University, Faculty of Agriculture in 2017, 2018 and 2019 in Adana
(Mediterranean Region)-Turkey. The objective of this study was to
compare of fatty acids composition and oil quality factors of different
market type peanut (Arachis hypogaea L.) varieties grown as a main crop.
Four different market type peanut varieties, including Virginia
(Halisbey), Runner (G.Green), Spanish (Florispan) and Valencia (G.Red)
were used as plant material in this research. The experimental design
was a randomized complete block design with three replications. Oil
content, fatty acids composition such as oleic acid, linoleic acid,
stearic acid palmitic acid and oil quality factors such as
Oleic/linoleic acid ratio (O/L) and iodine value (IV) of peanut seed oil
were investigated. According to a three-year results; the oil content of
the peanut varieties varied between 45.38% and 51.28%. The total
saturated fatty acid was higher in Spanish and Valencia types than
Virginia and Runner types. On the other hand, the total unsaturated
fatty acid was higher in Virginia and Runner types than the others
types.
Novel reversible CLA, optimized RCA and parallel adder/subtractor circuits
Authors: Gharajeh Mohammad , Haghparast Majid
Published: December 2020

This paper proposes reversible circuit designs of the three most commonly
used adders: carry look-ahead adder (CLA adder), ripple carry adder (RCA
adder), and parallel adder/subtractor. The n-bit reversible CLA adder,
called CLA-GH, is designed using the Peres and Fredkin gates. The n-bit
optimized reversible RCA adder, called ORCA-GH, is designed using the
reversible circuit of a parity-preserving reversible full adder. Both
circuits reduce the quantum cost. However, the ORCA-GH circuit also improves
the number of constant inputs. Furthermore, the n-bit reversible parallel
adder/subtractor, called PAS-GH, is designed using the Feynman, Peres, and
Fredkin gates. It decreases the number of garbage outputs and quantum cost.
The transistor realizations of the CLA-GH and PAS-GH circuits are provided
accordingly. The evaluation results indicate that the proposed circuits
surpass the existing works in all figures of merit.

Published: December 2020

The concept of Smart City started its development path around two to three
decades ago; it has been mainly influenced and driven by radical changes in
technological, social and business environments. Big Data, Internet of
Things and Networked Cyber-Physical Systems, together with the concepts of
Cloud, Fog and Edge Computing, have tremendous impact on the development of
Smart City, reforming its frame and tasks and redefining its requirements
and challenges. We consider feasible architectures of the IT infrastructure
and signal processing, taking into account aspects of Big Data, followed by
summary of benefits and main challenges, like security of infrastructure and
private data. As a practical example we present a public safety application
of multi-sensor imaging system: a smart device with target detection
subsystem based on artificial intelligence used for activation of target
tracking. The experiments have been performed in the cities of Abu Dhabi and
Belgrade, which have very different environment. The experiments have shown
the effects of videostreaming compression on thermal imagers and the
importance of distributed processing power that optimizes requirements for
amount of transmitted data and delay.
Analysis of conductive and convective transfers in a double salience switched reluctance machine by analytical coupling-2D finite elements
Authors: Souad Badache
Published: December 2020

The work presented in this paper concerns the study of the thermal behavior
due to copper losses and iron losses of a switched reluctance machine with
double salience (SRM6/4) by analytical coupling - 2D finite elements.
Calculation by analytical methods of the conduction coefficients in the
radial and axial direction as well as the convection coefficients in the air
gap of this machine are presented. The values of these found coefficients
are used to solve the transient thermal problem for this device using the
ADEMEF2D software. The obtained results show a very large increase in
temperature at the winding. Heat conduction in both radial and axial
directions has a very large effect on the temperature value in all regions
of the SRM6/4.
Do Needleless Connector Manufacturer Claims on Bidirectional Flow and Reflux Equate to In Vitro Quantification of Fluid Movement?
Authors: Gibson S. Matthew , Primeaux Jonathan
Published: December 2020

Highlights

NC labeling does not appear to correspond with manufacturer claims. Two of 13 NCs passed the test for bidirectional flow control. All NCs reflux either on connection or disconnection. Neutral displacement does not appear to be present in the NCs tested in this observational study. Accurate bidirectional flow control, reflux cycle, and volume of reflux beyond the manufacturer’s performance claims will assist in the proper use of NCs.
Regnskapsspråk og informasjonskvalitet hos selskaper notert på uregulerte markedsplasser
Authors: Opstad André , Stenheim Tonny , Baksaas Kjell Magne , Stephansen Sissel With , Meidelsen Kirsti
Published: December 2020

I dette kapittelet vurderer vi informasjonskvaliteten til regnskaper utarbeidet av selskaper notert på de uregulerte markedsplassene Merkur Market, NOTC og «Family and Friends» per 31.12.2018.1 Studien bygger på en antagelse om at regnskaper utarbeidet etter IFRS, vil gi mer og bedre informasjon for investorer enn regnskaper utarbeidet etter God regnskapsskikk (GRS). Samtidig vil insentiver og press kunne medføre at selskaper som bruker GRS, gir mer informasjon enn det minimumskravene skulle tilsi, noe som gjør det nødvendig kvalitativt å vurdere den faktiske regnskapspraksisen (med utgangspunkt i sentrale avvik mellom IFRS og GRS). Vi observerer at mange selskaper velger å være organisert som aksjeselskap fremfor allmennaksjeselskap, velger GRS som regnskapsspråk fremfor IFRS og generelt utarbeider regnskaper med lav informasjonskvalitet. Spesielt er det uventet at så mange små foretak velger å benytte forenklingsregler når de samtidig ønsker å hente inn risikovillig kapital i et notert aksjemarked. Interessant nok er det selskapene notert på Merkur Market, som er nivået før ordinær børsnotering på Oslo Børs (Hovedlisten) og Oslo Axess, som avgir regnskaper med lavest informasjonskvalitet. Våre observasjoner avdekker svakheter ved informasjonskvaliteten på flere sentrale områder. Dette kan medføre høyere kapitalkostnad, mindre tilgang på kapital og lavere likviditet på aksjene til disse selskapene. En markedsløsning for produksjon av regnskapsinformasjon hvor omfang og kvalitet på informasjonen bestemmes av tilbud og etterspørsel, synes ikke å fungere. Gjeldende regulering synes heller ikke å evne å ivareta investorenes informasjonsbehov i tilstrekkelig grad. Kapittelet viser at det trolig eksisterer for svake regnskapsplikter for selskaper notert på uregulerte markedsplasser.

Published: December 2020

The article examines the influence of the «Polish question» arising as the result of the division of the Polish-Lithuanian Commonwealth on the government policy pursued on Byelorussian lands in the first half of the 19th century. Remaining unchanged in its essence, the forms and methods of this policy changed depending on the political situation in the Byelorussian-Lithuanian region. The «Polish question» manifested itself most vividly in the class, legislative, national-religious policy and in education.
Training of Village Teachers in Vilna Educational District in the 1860s and 1870s
Authors: Komzolova Anna A.
Published: December 2020

One of the results of the educational reform of the 1860s was the formation of the regular personnel of village teachers. In Vilna educational district the goal was not to invite teachers from central Russia, but to train them on the spot by establishing special seminaries. Trained teachers were supposed to perform the role of «cultural brokers» – the intermediaries between local peasants and the outside world, between the culture of Russian intelligentsia and the culture of the Belarusian people. The article examines how officials and teachers of Vilna educational district saw the role of rural teachers as «cultural brokers» in the context of the linguistic and cultural diversity of the North-Western Provinces. According to them, the graduates of the pedagogical seminaries had to remain within the peasant estate and to keep in touch with their folk «roots». The special «mission» of the village teachers was in promoting the ideas of «Russian elements» and historical proximity to Russia among Belarusian peasants.
Pinsk General Congregation of Orthodox Clergy in 1791 as the First Experience of Hostile Actions of the Phanar Against Russian Orthodox Church
Authors: Romanchuk Protopriest Alexander
Published: December 2020

The article examines the little-known event in the Church history of the Western Russian region – the Pinsk General Congregation of 1791, which put on its agenda the issue of the subordination of the Orthodox population in Poland to the authority of the Patriarch of Constantinople. The author traces the premises, course and significance of this meeting of the Orthodox clergy of the Polish-Lithuanian Commonwealth, as well as the role of the Patriarch of Constantinople Neophytos VII in its holding and his guiding motives. It is concluded that: 1) the Pinsk Congregation was an unlawful assembly from the canonical point of view, and it served to intensify the actions of the Russian Empire against the Polish statehood; 2) the motives for the support of the Congregation on the part of the leadership of the Patriarchate of Constantinople were the idea of the universal power of Constantinople in the Orthodox world, and also the Greek nationalism; 3) the assistance to the separatist movement of the Orthodox clergy in the Polish-Lithuanian Commonwealths in 1791 became, chronologically, the first experience of Phanar’s hostile actions against Russian Orthodox Church.

Utopía y revolución
Authors: García Sánchez Carlos
Published: December 2020

En este artículo se analizan algunos aspectos teóricos e ideológicos que determinaron que las vanguardias artísticas se comprometieran en la construcción y el desarrollo de lo que Jean Francoise Dupuis (2004) ha llamado «estética radical», con el objetivo de mostrar que conceptos como utopía y revolución se vuelven fundamentales para poder entender el modo en el que las vanguardias de principios del siglo entendieron tanto su labor artística como su función social y política. Para ello, se reflexiona acerca del concepto de utopía y las problemáticas que encierra esta noción; se considera que este modelo utópico estuvo fuertemente vinculado a la idea clásica de revolución, la cual estaba inserta en el imaginario de las vanguardias artísticas. Por último, se analizan diferentes enfoques sobre el realismo con la idea de poder esbozar una reinterpretación del concepto de utopía.
Nuevas perspectivas sobre la autoría de La fuente
Authors: Arrieta Gutiérrez Paula
Published: December 2020

Nuevas investigaciones y la aparición en los años ochenta de una carta de Marcel Duchamp a su hermana han revivido la discusión en torno a la autoría de La fuente, pieza decisiva del arte moderno y contemporáneo. En este artículo se presenta una revisión actualizada de la discusión con el propósito de ordenar los argumentos, identificar los procesos inductivos presentes y proponer posibles caminos críticos que apuntan principalmente a la construcción de la historia del arte alrededor de un hito, la invisibilización de la participación de las mujeres en ello y los cruces y contaminaciones que determinan la producción artística de una época. El objetivo no es establecer una verdad, sino exponer la documentación existente y traer uno de los hitos más importantes de la historia del arte al presente, como una manera dinámica de reconstruir los relatos que determinan sus sentidos.

Introdução. A Dengue é uma doença grave causada por arbovírus da família Flaviviridae, transmitidos por picadas de insetos, especialmente pelos mosquitos Aedes aegypti, que precisa de água parada para sua proliferação. Por isso a importância de manter a higiene e evitar água parada. Pessoas de todas as faixas etárias são igualmente suscetíveis a dengue, contudo os idosos possuem maior risco de desenvolver quadros graves e complicações que podem levar à óbito. No atual contexto da pandemia de COVID-19 torna-se ainda mais urgente a implementação de ações de monitoramento, prevenção e controle, visando que as ações ocorram precocemente à efetividade das estratégias de enfrentamento da disseminação da dengue. Objetivos. Os objetivos desta pesquisa de vigilância epidemiológica da incidência da dengue no litoral paranaense são o monitoramento, prevenção e a publicização de casos novos de dengue para o planejamento de estratégias de redução do número de casos e da ocorrência de surtos no litoral paranaense. Metodologia. Utilizou-se a técnica de monitoramento epidemiológico comparativo das informações sobre o total dos casos confirmados e a incidência de autóctones (por 100.000 habitantes por município) da dengue nos sete municípios do Paraná, publicadas no boletim da Secretaria da Saúde do Estado do Paraná (SESA/PR)[1]  referentes à última Semana Epidemiológica disponível de cada mês, de janeiro a julho de 2019 e 2020.

Aspects of the relationship between the processing of stimuli in the peripheral perceptual field and in the perceptual central field
Authors: Aniței Mihai , Mincu Cornel Laurențiu , Chraif Mihaela
Published: December 2020

As humans have limited information processing abilities and rely on three fallible mental functions: perception, attention and memory, the driving error is easy to appear. The purpose of this paper is to highlight the male/female differences in processing the perceptive information from the external stimuli in the peripheral visual field and to demonstrate that the mean of the estimate errors in evaluating the speed and distances in the central visual perceptual field is in inverse ratio to the reaction time value at the visual stimuli from the peripheral driving tasks simulation. Between the variables number of wrong reactions and number of omissions there has been obtained a relatively high negative correlation (r=-0.728, p<0.001). The result has a strong implication in visual stimuli processing during driving tasks.

Prasarana Lingkungan yang baik adalah prasarana yang memungkinkan lingkungannya dapat berfungsi sebagaimana mestinya. Gang Masjid di jalan Lambung Mangkurat Samarinda dikenal sebagai Kampung Fashion merupakan kawasan permukiman padat penduduk yang rentan terhadap bencana banjir dan kebakaran. Hal ini disebabkan kondisi prasarana lingkungan yang tidak memadai seperti jalan yang sempit dengan kepadatan lalu lintas yang tinggi, kepadatan bangunan yang saling berhimpit, kondisi bangunan yang didominasi dinding kayu, sistem drainase yang buruk dan fasilitas pembuangan sampah yang tidak memadai serta fasilitas pemadam kebakaran yang minim menyebabkan tinggi nya resiko terhadap bencana banjir dan kebakaran. Untuk mengurangi tingginya resiko terhadap bencana kepedulian warga terhadap lingkungannya perlu ditingkatkan. Melatih warga tanggap terhadap bencana dapat meminimalkan kerugian akibat terjadinya bencana.

Published: December 2020

Object and purpose of research. This paper discusses the results of experimental studies in radar imaging of marine objects, as well as the measurements of radar cross-section (RCS) and 2D radar portraits in natural conditions as per integrated synthetic aperture radar (ISAR) approach.

Materials and methods. The measurements were carried out in full-scale conditions using an X-band instrumentation radar. RCS measurements were performed with radar pulse length exceeding the size of an object; the impulse with a length of about 1 m was used to obtain 2D portraits.

Main results. A qualitative and quantitative comparison of the measurement results with the use of "long" and "short" pulses, as well as the type assessment of statistical RCS distribution of marine object.

Conclusion. The studies made it possible to confirm the previously proposed theory that average RCS of a marine object may be derived through RCS summation of all its local sources. The closeness of the statistical RCS distribution for a marine object to the lognormal distribution was also experimentally confirmed.

Authors: Zimmerman Justin , Allen Christopher
Published: December 2020

A 45-year-old man presented to an emergency department reporting back pain, bilateral lower extremity weakness with paresthesia, and 1 episode of bladder incontinence. Radiographs and magnetic resonance imaging of the thoracolumbar spine were negative for cauda equina syndrome and positive for central canal stenosis and cord signal change from T2 to T4. The emergency department referred him to his primary care provider, who referred him to physical therapy. Following examination, due to the progressive neurological compromise correlated with magnetic resonance imaging findings, the physical therapist contacted neurosurgery for immediate referral. Two days later, the patient underwent emergency thoracic laminectomies, without fusion, for decompression of the spinal stenosis had resulted in thoracic myelopathy.

Air-Carbon Ablation Model for Hypersonic Flight from Molecular Beam Data
Authors: Prata Krishna Sandeep , Minton Timothy , Schwartzentruber Thomas E.
Published: December 2020

Recent molecular beam experiments of high velocity O, N, and O2 impacting carbon material at high temperature produced detailed surface chemistry data relevant for carbon ablation processes. New data on O and N reactions with carbon has been published using a continuous molecular beam with lower velocity (2000 m/s) and approximately 500 times higher beam flux than previous pulsed-beam experiments. This data is interpreted to construct a new air-carbon ablation model for use in modeling carbon heat shield ablation. The new model comprises 20 reaction mechanisms describing reactions between impinging O, N, and O2 species with carbon and producing scattered products including desorbed O and N, O2 and N2 formed by surface-catalyzed recombination, as well as CO, CO2, and CN. The new model includes surface-coverage dependent reactions and exhibits non-Arrhenius reaction probability in agreement with experimental observations. All reaction mechanisms and rate coefficients are described in detail and each is supported by experimental evidence or theory. The model predicts pressure effects and is tested for a wide range of temperatures and pressures relevant to hypersonic flight. Model results are shown to agree well with available data and are shown to have significant differences compared to other models from the literature.

Published: December 2020

Cinacalcet (INN), a calcium mimetic drug that mimics the activity of calcium in the body. It expresses itself by activation of calcium-sensing receptor allosterically in different organs and tissues. The secretion of parathyroid hormone is regulated principally by calcium-sensing receptors that are present on the surface of the parathyroid gland. Cinacalcet is used in the treatment of hyperparathyroidism, which is the usual consequence of parathyroid cancers and CKF. There had been a rapid increase in the number of drugs that are adding to each class of drugs. These drugs are formulated into newer formulations either in a single or multi-drug dosage forms. These newer marketed formulations demand a new investigation for the estimation of the drug in the formulations. The existing analytical techniques for those drugs are available in the research literature, but not all the methods are stable and economical to use. The objective of this work was to develop an analytical RP-HPLC method for the estimation of cinacalcet in bulk and tablet formulation. The emphasis was given to the short time of analysis, and simplicity in the method. RP-HPLC analysis of the drug satisfies the peak integrity, suitability, recovery of the drug. LOQ and LOD of the drug were achieved with high sensitivity. The data shows the precision of the method and the accuracy of the method. Overall, the data suggest that the proposed analytical method can be used to analyse the drug in the formulation. This method can be recommended for the routine analysis of the drug in its dosage form.
