Authors: Bittencourt Mauricio Vaz Lobo , Correa Natássia Zanotto
Published: March 2021

Diante da adoção de um sistema de taxas de câmbio flutuante, após a quedado sistema monetário Bretton Woods, vários países passaram a experimentar o aumento da variabilidade da taxa de câmbio, com diversas consequências para as suas economias. O objetivo central deste estudo consiste em analisar o efeito da volatilidade dataxa de câmbio sobre o comércio brasileiro a nível setorial, dito diferentemente, sobre acomposição da pauta de exportação brasileira. Para tanto, considera-se o volume exportado do Brasil para seus principais parceiros comerciais no período de 2001 a 2017, e, posteriormente, realiza-se uma classificação dos produtos em três categorias (básicos, semimanufaturados e manufaturados). A par¬tir de tal agrupamento, a composição da pauta de exportação é definida pela participação de cada categoria de produto no total do volume exportado para os respectivos parceiros. Adicionalmente, essa variável éutilizada como dependente em um modelo gravitacional de comércio, o qual é estimado usando-se os métodos de mínimos quadrados ordinários agrupado, econometriade painel e Poisson pseudo maximum likelihood. Os resultados obtidos indicam que avolatilidade cambial tem um efeito adverso apenas sobre o setor de manufaturas, comefeito positivo nas exportações de produtos básicos e nenhum efeito significativo sobreo comércio de produtos semimanufaturados.

Published: March 2021

Melanoides tuberculata é uma espécie exótica de molusco já disseminada na maioria dos ambientes aquáticos do Brasil. O objetivo desse trabalho foi analisar se há relação das medidas alométricas e da biomassa de M. tuberculata com a gradiente de eutrofização em reservatórios. O estudo foi realizado em três reservatórios localizados na bacia do rio Paraíba, Nordeste do Brasil. O índice de estado trófico (IET) de Carlson, modificado por Toledo, foi aplicado para classificação trófica. Os resultados mostram a formação de três grupos entre os locais de amostragem com base no IET. Nos sites com maiores valores de IET foram encontrados os maiores tamanhos do molusco. Enquanto nos sites com níveis médios de eutrofização, os indivíduos tiveram comprimento intermediário. No grupo com a menor média de eutrofização, foram encontramos os menores comprimentos de M. tuberculata. A biomassa variou entre os grupos. As medidas alométricas estiveram relacionadas ao gradiente de eutrofização, especialmente quando se considerou, separadamente, as concentrações de fósforo e clorofila. Os resultados obtidos mostram que relações entre medidas alométricas de M. tuberculata e variações nas concentrações de fósforo e clorofila apresentam grande potencial para a avaliação da qualidade ambiental de reservatórios no semiárido do Brasil.

As Áreas de Preservação Permanente (APP) são regulamentadas através da Lei Federal nº 12.651/2012. Essa Lei atua como instrumento regulador no processo de tomada de decisão para minimizar os problemas socioambientais, causados pelas diversas interferências antrópicas. Desta forma, esse artigo teve como objetivo geral analisar as unidades de paisagem em APP urbanas das cidades de Aracaju/SE e Blumenau/SC. Para construção desse estudo, foi elaborada uma análise comparativa entre trechos, de cada município, que apresentaram fortes ações antrópicas, sendo este o critério de escolha. Em Blumenau, utilizou-se como área de abrangência a da microbacia do Ribeirão Fresco; e em Aracaju, utilizou-se como área de abrangência a do rio Poxim. Os procedimentos metodológicos desse estudo foram ramificados em 3 etapas: revisão bibliográfica; visitas técnicas e sistematização dos dados, utilizando-se técnicas de Geoprocessamento, levantamento fotográfico e análise de documentos. Observou-se que nas duas regiões há problemáticas socioambientais semelhantes, a exemplo da ocupação (construções) em áreas destinadas às APP. Através dessas ocupações, as pressões antrópicas tornaram-se maiores, resultando em problemas como enchentes, deslizamentos de terra, descarte incorreto de resíduos sólidos, entre outros. Por fim, espera-se que, com os resultados apresentados, haja intervenção do poder público, nessas áreas protegidas juridicamente, com a formulação de políticas públicas efetivas, conservando a função socioambiental das APP.
International barriers and facilitators for cervical cancer screening among young people: a systematic review
Authors: Kirubarajan Abirami , Leung Shannon , Li Xinglin , Yau Matthew , Sobel Mara
Published: March 2021

Background Though cervical cancer is one of the leading causes of death
globally, its incidence is nearly entirely preventable. Young people
have been an international priority for screening. However, in both
high-income and low-income countries, young people have not been
screened appropriately according to country-specific guidelines and in
many countries, screening rates for this age-group have even dropped.
Objectives The aim of this systematic review was to systematically
characterize the existing literature on barriers and facilitators for
cervical cancer screening among young people globally. Search Strategy
We conducted a systematic review following PRISMA guidelines of four
databases: Medline-OVID, EMBASE, CINAHL, and ClinicalTrials.Gov.
Selection Criteria We only examined original, peer-reviewed literature.
Databases were examined from inception until the date of our literature
searches (12/03/2020). Articles were excluded if they did not
specifically discuss cervical cancer screening, were not specific to
young people, or did not report outcomes or evaluation. Data Collection
and Analysis All screening and extraction was completed in duplicate
with two independent reviewers. Main Results Of the 2177 original
database citations, we included 36 studies that met inclusion criteria.
Our systematic review found that there are three large categories of
barriers for young people: lack of knowledge/awareness, negative
perceptions of the test, and practical barriers to testing. Facilitators
included stronger relationships with healthcare providers, social norms,
support from family, and self-efficacy. Conclusions Health systems
worldwide should address the barriers and facilitators to increase
cervical cancer screening rates in young people. Further research is
required to understand this age group.
Energy selection functions: modelling the energetic drivers of animal movement and habitat use
Authors: Klappstein Natasha J. , Potts Jonathan , Michelot Théo , Börger Luca , Pilfold Nicholas , Lewis Mark , Derocher Andrew
Published: March 2021

1. Energetics are a key driver of animal decision-making, as survival
depends on the balance between foraging benefits and movement costs.
This fundamental perspective is often missing from habitat selection
studies, which mainly describe correlations between space use and
environmental features, rather than the mechanisms behind these
correlations. To address this gap, we present a new modelling framework,
the energy selection function (ESF), to assess how moving animals choose
habitat based on energetic considerations.

2. The ESF considers that the likelihood of an animal selecting a
movement step depends directly on the corresponding energetic gains and
costs. The parameters of the ESF measure selection for energetic gains
and against energetic costs; when estimated jointly, these provide
inferences about foraging and movement strategies. The ESF can be
implemented easily with standard conditional logistic regression
software, allowing for fast inference. We outline a workflow, from
data-gathering to statistical analysis, and use a case study of polar
bears (Ursus maritimus) as an illustrative example.

3. We show how defining gains and costs at the scale of the movement
step allows us to include detailed information about resource
distribution, landscape resistance, and movement patterns. We
demonstrate this in the polar bear case study, in which the results show
how cost-minimization may arise in species that inhabit environments
with an unpredictable distribution of energetic gains.

4. The ESF combines the energetic consequences of both movement and
resource selection, thus incorporating a key aspect of evolutionary
behaviour into habitat selection analysis. Because of its close links to
existing habitat selection models, the ESF is widely applicable to any
study system where energetic gains and costs can be derived, and has
immense potential for methodological extensions.
Fungal diversity in high Andean ecuadorian forest soil
Authors: Valdez Adrian , Covarrubias Sergio
Published: March 2021

The Andes range in Ecuador presents high biodiversity and characteristic
altitudinal gradients, which are frequently threatened by deforestation
and farming. In particular, forest have developed in the high
inter-Andean alley on volcanic soils forming a unique ecoregion. Little
is known on the fungal biodiversity of soil in such high Andean gallery
forest submitted to strong degradation pressures. Therefore, in this
study we evaluated wether the soil mycobiome was associated with
altitudinal gradients during the dry season. Three representative
locations were selected based on altitude: A (3,309 meters above the sea
level, masl), B (3,809 masl) and C (4,409 masl). High performance
sequencing (NGS) of the ITS region of ribosomal DNA genes with Illumina
technology was used to explore the fungal taxonomic composition in the
soil samples. Our results showed changes in the structure of fungal
communities in the different locations, related to the relative
abundance of Amplicon Sequence Variants (ASV). Higher fungal diversity
was related with the altitudinal gradient with average taxa ranging from
675, 626 and 556 ASVs, respectively from location A to C. The results
highlight the complexity and diversity of fungal communities in high
Andean forest and the need to protect these unique mycobiomes. The
findings in this ecosystem of Ecuador will improve our understanding of
distribution, diversity, ecology, and biological perspectives for the
restoration of terrestrial microbiomes.
ASCVD in LATAM: A Call for Action on LDL-C Reduction ASCVD in LATAM: A Call for Action on LDL-C Reduction
Authors: Corral Pablo , Lopez Abel Alberto Pavia , Giunta Gustavo , Buitrago Andres Felipe , Saraiva Jose Francisco Kerr
Published: March 2021

Background and Aims: As a result of the current demographics,
increased projections of atherosclerotic cardiovascular disease (ASCVD)
and prevalence of the disease in Latin America (LA), a panel of
multidisciplinary experts developed a review of ASCVD in this Region
considering the available and appropriate diagnostic methods,
classifying the disease and initiating appropriate treatment. The panel
expects to increase the awareness of this prevalent disease, decrease
consequences of ASCVD with corresponding cost savings and, ultimately,
decrease the overall burden of ASCVD in LA. Methods: A selected
panel of Latin American experts in fields related to ASCVD were provided
with a series of relevant questions to address prior to the multi-day
conference. Within this conference, each narrative was discussed and
edited by the entire group, through numerous drafts and rounds of
discussion until a consensus was achieved. Results: The authors
propose specific and realistic recommendations for increasing the
awareness of ASCVD in LA and in other countries in a similar situation.
Moreover, in creating these recommendations, the authors strived to
address all barriers and impediments mentioned previously within this
review. Conclusion: This manuscript provides a review of the
current state of ASCVD in LA. Additionally, the panel proposes practical
recommendations that should be implemented throughout the Region in
order to decrease the burden of ASCVD and effectively preventing the
consequences in future generations. These recommendations can serve as a
framework for LA and other countries in similar situations.
Engaging the next generation of editorial talent through a hands-on fellowship model
Authors: Deemer Bridget , Hotaling Scott , Poulson-Ellestad Kelsey , Falkenberg Laura , Cloern James , Soranno Patricia
Published: March 2021

Peer-review and subject-matter editing is the backbone of scientific
publishing. However, early career researchers (ECRs) are given few
opportunities to participate in the editorial process beyond reviewing
articles. Thus, a disconnect exists: science needs high-quality
editorial talent to conduct, oversee, and improve the publishing
process, yet we dedicate few resources to building editorial talent nor
giving ECRs formal opportunities to influence the publishing landscape
from within. Here, we describe a “two-way” fellowship model that gives
ECRs a “seat” at the editorial table of a field-leading journal. We
describe both the necessary framework and benefits that can stem from
editorial fellowships for ECRs, editors, journals, and the scientific
community.

Sarcoidosis afflicts the central nervous system more frequently than previously believed. Neurological symptoms are present in roughly one-half of patients, and depend on the location in the central nervous system. The probability of spontaneous regression is significantly less when compared to other forms of sarcoidosis, which means that the proper diagnosis and treatment is paramount. Even when properly treated, functional defects are not uncommon. Majority of these patients require immunomodulating drugs and continuous follow-up. New immunomodulating drugs, especially biological agents, have shown to be significantly more effective, with fewer side effects, and are important when corticosteroids could not be applied. Less invasive methods, such as cerebrospinal analysis, help greatly in the diagnostics procedure, and require further research and improvement.
In Defense of Limited Manufacturing Cost Control: Disciplining Acquisition of Private Information by Suppliers
Authors: Arya Anil , Mittendorf Brian , Ramanan Ram N. V.
Published: March 2021

When a firm's input supplier can acquire and misreport private information to gain an edge in negotiations, we show that the firm can blunt the supplier's informational advantage by permitting inefficiencies in its own internal production. Specifically, we establish that a modest increase in the cost of the input(s) a firm makes internally credibly commits it to be more aggressive in negotiations with a supplier for the input(s) the firm buys. Recognizing that its potential information rents will be limited, the supplier, in turn, becomes less aggressive in information acquisition. The paper fully characterizes the equilibrium—the firm's investments, the supplier's information acquisition and reporting decisions, and the terms of trade—to demonstrate that often-maligned internal bloat can be an endogenous facilitator of efficient outsourcing.
The Effect of Staff Auditor Reputation on Audit Quality Enhancing Actions
Authors: Blum Emily S. , Hatfield Richard C. , Houston Richard W.
Published: March 2021

Auditors often face situations in which acting on their professional obligations comes with potential personal costs. Drawing upon the Theory of Reputation in Organizations, we predict that perceived costs associated with these actions are lower for auditors with positive reputations, which, in turn, influences their actions. In our first experiment, participants perceive that auditors with negative reputations face a more constrained choice set when anticipating a budget overage. Further, participants perceive that those with positive reputations are more likely to proactively report the overage and less likely to underreport hours worked, a result mediated by the anticipated impact on evaluations for “speaking up.” In a second experiment, we manipulate reputation in a live simulation and demonstrate a causal link between reputation and auditors' skeptical action. Taken together, our experiments provide evidence that an auditor's perceived reputation influences their choice to engage in audit quality enhancing behaviors.
The Revolving Door between Large Audit Firms and the PCAOB: Implications for Future Inspection Reports and Audit Quality
Authors: Hendricks Bradley E. , Landsman Wayne R. , Peña-Romera F. Dimas
Published: March 2021

This study examines whether audit firms hire former PCAOB employees in response to negative PCAOB inspection reports, and whether such hiring leads to reductions in future inspection deficiencies and an increase in audit quality. We find that the number of PCAOB employees hired by large audit firms is positively related to the number of deficiencies reported in their prior inspection reports, and that the number of deficiencies reported in firms' future inspection reports is negatively associated with the number of former PCAOB employees hired. However, we find no significant association between the number of former PCAOB employees that a firm hires and improvement in audit quality. These findings suggest that former PCAOB personnel possess valuable knowledge about how to perform and document audit procedures to satisfy PCAOB reviewers, but that this expertise does not necessarily have direct implications for the accuracy and reliability of clients' financial reports.

Authors: Bancks Michael P. , Chen Haiying , Balasubramanyam Ashok , Bertoni Alain G. , Espeland Mark A. , Kahn Steven , Pilla Scott , Vaughan Elizabeth , Wagenknecht Lynne E. , Group the Look AHEAD Research
Published: March 2021

Objective: We re-evaluated the Action for
Health in Diabetes (Look AHEAD) intervention, incorporating diabetes subgroups,
to identify whether intensive lifestyle intervention (ILI) is associated with
differential risk for cardiovascular disease (CVD) by diabetes subgroup.

Research Design and
Methods: Look
AHEAD randomized 5145 participants, aged 45-76 years, with type 2 diabetes
(T2D) and overweight or obesity, to 10 years of ILI or a control condition of
diabetes support and education. ILI focused on weight loss through decreased
caloric intake and increased physical activity. To characterize diabetes subgroups,
we applied k-means clustering to data for age of diabetes diagnosis, body mass
index, waist circumference, and glycated hemoglobin. We examined whether
relative intervention effects on the trial’s prespecified CVD outcomes varied
among diabetes subgroups.

Results: We characterized four subgroups
related to older age at diabetes onset (42% of sample), poor glycemic control
(14%), severe obesity (24%), and younger age at onset (20%). We observed
interactions (all p<0.05) between intervention and diabetes subgroup for
three separate composite cardiovascular outcomes. Randomization to ILI was
associated with increased risk for each cardiovascular outcome only among the
poor glucose control subgroup (hazard ratios, HR >1.32). Among the three
other diabetes subgroups, ILI was not associated with increased risk for CVD.

Conclusion: Among overweight and obese adults
with T2D, a lifestyle intervention was associated with differential risk for
CVD that was dependent on diabetes subgroup. Diabetes subgroups may be
important to identify the patients who would achieve benefit and avoid harm
from an intensive lifestyle intervention.
UTILIZATION OF BETEL LEAVES EXTRACT TO PREVENT THE GROWTH OF Fusarium oxysporum f.sp. capsici CAUSING FUSARIUM WILT DISEASE IN BELL PEPPER
Authors: Leana Ni Wayan Anik , Suprapta Dewa Ngurah
Published: March 2021

Betel (Piper betle Linn.) is commonly used in Indonesian traditional medicine due to its antimicrobial properties, thus it is often used as an ingredient in natural pesticides. The effectiveness of betel leaf extract as a control for Fusarium oxysporum in several plants showed it’s potential to control the fungi in bell pepper. F. oxysporum f.sp. capsici is one of the important pathogens causing Fusarium wilt disease in bell pepper. It is one of the most devastating plant diseases due to its ability to cause a crop failure. The test on the inhibitory capacity of betel leaf extract on the growth of F. oxysporum f.sp. capsici were carried out by growing the fungi on PDA mixed with various concentrations of betel leaf extracts. The results showed that betel leaf extract treatment at 0.02% concentration was able to inhibit the growth of F. oxysporum f.sp. capsici in PDA at 95.54%. The full inhibition of colony growth (100%) was achieved in the extract treated with the concentration of 0.03%. Meanwhile treatment of 0.17% betel leaf extract was able to inhibit the growth of F. oxysporum f.sp. capsici on bell pepper stems. Following this result, fractionation of the betel leaf extract by column chromatography was conducted, resulting in 44 fractions. The bioassays of those fractions showed that, there were seven fractions that reveal inhibition capability against F. oxysporum f.sp. capsici.
AVIAN SPECIES COMPOSITION PROFILE AND FEEDING GUILDS UNDER THE AEROBIC RICE FIELD
Authors: Amzah Badrulhadza , Baki Razali , Yahya Mohd Hafizi
Published: March 2021

In Malaysia, the aerobic rice production system is an alternative approach to growing rice in a water-scarce environment. Like irrigated rice, aerobic rice also can sustain a diversity of avian fauna. The current status of birds in the rice fields of Malaysia especially under aerobic rice condition has not been widely researched. Therefore, this study aims to document the richness, diversity and feeding guilds of bird species in aerobic rice cultivation area. Birds were sampled and recorded using four randomly set up mist net at an upscaling aerobic rice plot in Serdang, Selangor during a period of the one month starting from the milky stage of the plant (75 days after emergence) until two weeks after harvest. 139 birds representing 11 species belonging to 7 families were recorded in the aerobic rice plot. The most abundant bird family observed was Estrildidae (80.58%), followed by Hirundinidae (6.47%), and Meropidae and Motacillidae (both recorded 5.04%). Scaly-breasted munia (50.36%) and white-headed munia (28.06%) are the most abundant birds, while other types of munia such as chestnut munia and white-rumped munia are present in small numbers. Munias were the most observed bird species number (36.36%) and therefore can be considered as the main avian pest of aerobic rice. The diversity indices, The Shannon-Wiener Index was 1.43 while The Reciprocal Simpson Index was 2.93. The richness index (The Margalef Index) was 2.03. The Equitability Index was 0.59. In term of feeding guild, most species belong to insectivore (45.45%) and granivore (36.36%) while the rest were piscivore/insectivore and granivore/insectivore. However, the granivore recorded the highest number of individuals (112 or 80.58%) compared to other guilds. Presence of a relatively high diversity of bird species with varieties of feeding guilds indicated that aerobic rice does provide an attractive habitat or foraging site for avian fauna.
Correlates of Actual and Self-Reported Knowledge and Skills, Attitudes, and Barriers Mitigating Against the Implementation of Evidence-Based Practice in Physiotherapy
Authors: Balogun Joseph , Mbada Chidozie E. , Oyeyemi Adetoyeje Y. , Awoleye Faith A. , Olakorede David B. , Balogun Adetutu
Published: March 2021

Background: Evidence-based practice (EBP) has in the last decade gained global prominence in healthcare professions including physiotherapy. Several studies have been conducted worldwide to determine physiotherapists' knowledge, attitudes, beliefs, behaviors, skills, and resources, and barriers mitigating against the implementation of EBP in physical therapy, but there is limited information on the correlation among actual (competence) and self-report (perceived) knowledge and skills about EBP.

Methods: This cross-sectional study investigated the premise of these associations among 233 Nigerian physiotherapists who completed a previously validated 55-item questionnaire that assessed demographic data, actual and self-report knowledge, skills and resources, attitudes, and barriers about EBP.

Result: We found no significant relationship between actual knowledge of EBP and clinical experience (r=.086, p>.05), age (r=.048, p>.05), academic degree (r=.108, p >.05), self-reported knowledge (r=.097, p>.05), and self-reported skills about EBP (r=.095, p>.05). Demographic variables (age, years of clinical experience, and academic degrees) and psychosocial factors (self-reported knowledge, skills and resources, attitudes, and barriers about EBP) are not a significant predictor of actual knowledge of EBP.

Conclusion: The physiotherapists perceived that they are competent about EBP but in reality, they are not, and may fail to seek educational resources that will improve their understanding and improve their skills about EBP.

Authors: Mazzini Clementina , Ficoseco Verónica Sofía
Published: March 2021

Este artículo analiza los discursos circulantes en torno a las mujeres y los feminismos en las páginas de Facebook de los medios de comunicación escrita La Garganta Poderosa y La Nación. La metodología utilizada fue de enfoque etnográfico virtual y la técnica principal de producción de datos fue la observación no participante y registro de los comentarios encontrados. El trabajo de campo fue desarrollado online en las páginas mencionadas durante un mes, mientras que la fase analítica se basó en el análisis crítico de contenidos. Se definieron tres ejes de análisis: las críticas a las formas de militancia del feminismo actual, los estereotipos en torno a las mujeres, y el control de la sexualidad y los cuerpos femeninos y el colectivo LGBT. Entre los resultados se observó que a través de los comentarios violentos en las páginas analizadas, se construye una crítica hacia las formas actuales de militancia feminista relacionándolas con la inmoralidad, el rol de madre se reivindica como absoluto y obligatorio, y la sexualidad que desafía la norma heteropatriarcal se significa como peligrosa.

Published: March 2021

Este trabajo presenta los avances de un estudio en curso centrado en la conversación política generada alrededor de discursos paródicos de coyuntura publicados en distintas plataformas de redes sociales. La hipótesis de base de dicho estudio sostiene que el dispositivo sociotécnico de las interfaces y las características del lenguaje audiovisual condicionan los modos en los que la conversación política contemporánea ocurre en estos sitios, y ejercen influencia en las formas en las que la expresión política se dinamiza en la actualidad. 

El artículo aborda los videos paródicos virales del prosumer Matías Mazzagatti. Estos textos retoman productos de animación japonesa y hechos y actores de la coyuntura política argentina. La metodología seguida es el análisis comparativo entre YouTube, Facebook y Twitter observando las operaciones de sentido tanto en producción como en recepción. En producción se observaron las operaciones en relación al uso del lenguaje audiovisual y en recepción las operaciones en relación a los comentarios de los/as usuarios/as. Se evalúa la circulación de los textos seleccionados teniendo en cuenta la injerencia del dispositivo en la conversación política paródica. Concluimos que se pueden observar diferencias sociotécnicas entre las plataformas que habilitan distintas modalidades de conversación política en las redes sociales.

Published: March 2021

At present, the economic benefits of double inlet and double outlet ball mills, which are commonly used in coal-fired power plants, need to be improved. Based on this, this paper explores the factors influencing the output of double inlet and double outlet ball mill by establishing the output system of double inlet and double outlet ball mill. By analyzing the influence factors of the output of double inlet and double outlet ball mill, and combining with system dynamics, the dynamic model of double inlet and double outlet ball mill output system is established, and SPSS is used to fit the model data with the real data. The fitting degree is above 0.8, and the authenticity is high. The simulation results show that the impact energy of barrel grinding, the grinding powder fineness, and the pressure ratio in the ball mill affect the output of double inlet and double outlet ball mill according to certain relations. Finally, the research in this paper provides theoretical and technical support for improving the economic benefits of double inlet and double outlet ball mills.

Background/Aim: This study aimed to evaluate the effects of Lactobacillus reuteri lozenges as an adjunctive therapeutic agent in combination with scaling and root planning in a randomized, clinical trial of volunteers with periodontitis stage IV. Material and Methods: The study included 40 patients diagnosed with periodontitis divided into 2 groups of 20 patients by random sample method. The first group of patients used Lactobacillus reuteri lozenges after nonsurgical periodontal therapy for a period of 40 days while the second group of patients was treated with non-surgical periodontal therapy without lozenges. Periodontal clinical parameters were registered for all patients before treatment and after 40 days. Samples of saliva from patients before and 40 days after treatment were analyzed by the PCR method for pathogens Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, and Prevotella intermedia. Assessments were made on day 0 before treatment for patients of both groups and after 40 days. Results: Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis show a statistically significant difference between the two study groups. Results were not statistically significant for Prevotella intermedia (P= 0.5598). Conclusions: The present study confirms the positive effects of L. reuteri lozenges after non-surgical periodontal therapy and the maintenance phase of periodontal treatment. Considering the beneficial effects of probiotics, L. reuteri could serve as a useful adjunct or maybe even as an alternative to periodontal treatment when scaling and root planning might be contraindicated or has to be postponed.
Translation as a Catalyst in the Development of Modern Chinese Legal Language
Authors: Cao Deborah
Published: March 2021

This paper focuses on the translation of legal language and the development of modern Chinese legal language as a translated legal language. It first describes the historical contexts in which China underwent enormous and unprecedented social and political changes including changes to law in the late 1800s and early 1900s. It then discusses how translation played an important catalyst role in introducing Western law, legal practices, legal concepts and terminology in the emerging modern Chinese legal language as we know it today, and in the process, lent a helping hand in negotiating China’s transition to modernity through translation and creating a new legal language and legal system. It also considers the issues in translingual and cross-cultural communication and understanding translated Chinese legal language.

Authors: Chmielowiec Krzysztof , Boroń Agnieszka
Published: March 2021

Introduction: Recurrent use of psychoactive substances, including alcohol, affects most patients. It is an expression of the chronicity of the disease process. Understanding the causes of this phenomenon is the key to searching for effective therapeutic strategies for this disease.

The aim: Analysis of individual dimensions of personality traits in patients in the context of relapses.

Material and method: The research was carried out on a group of 301 people addicted to psychoactive substances staying in an addiction therapy center in Lubuskie and Zachodniopomorskie voivodships in Poland. The subjects were divided into two groups. The first group consisted of addicts with reported one-time therapy. The second group consisted of addicts who received at least two treatments at an addiction therapy center. The personality dimension was measured using the NEO-FFI questionnaire and the STAI questionnaire.

Results: The following percentages of neuroticism (NF NEUR) were marked in people addicted to psychoactive substances with a single stay in an inpatient treatment center: 8.55% with low intensity, 40.13% with moderate intensity and 51.32% with high intensity. On the other hand, in people addicted to psychoactive substances with multiple stays in an inpatient treatment center, the features of low-grade neuroticism were found to be 6.85%, 25.34% of moderate and 67.81% of high intensity (χ2 = 8.643, p = 0.013).

Conclusions: A higher score on the Nervousness Scale of the Neo FFI inventory has a significant impact on the course of addiction and the occurrence of relapses.

Authors: Goli Alireza , Tirkolaee Erfan Babaee , Weber Gerhard-Wilhelm
Published: March 2021

This paper addresses Acoustic Emission (AE) from Computer Numerical Control (CNC) machining operations. Experimental measurements are performed on the CNC lathe sensors to provide the power consumption data. To this end, a hybrid methodology based on the integration of an Artificial Neural Network (ANN) and a Shuffled Frog-Leaping Algorithm (SFLA) is applied to the data resulting from these measurements for data fusion from the sensors which is called SFLA-ANN. The initial weights of ANN are selected using SFLA. The goal is to assess the potency of the signal periodic component among these sensors. The efficiency of the proposed SFLA-ANN method is analyzed compared to hybrid methodologies of Simulated Annealing (SA) algorithm and ANN (SA-ANN) and Genetic Algorithm (GA) and ANN (GA-ANN).

Geotechnical measurements included equivalent soil cohesion, absolute and absolute deformation index, soil compressibility coefficient by time of immersion depth, exposure time to compressive strength to samples and physical and mechanical properties (humidity, density). Dataset was received from laboratory based experimental tests of the physical and mechanical properties of soils. Data were converted to csv table and processed by LaTeX. Methodology is based on LaTeX packages: {tikz}, {tikz-3dplot}, {tikzpicture}, {pgfplot}, {filecontetns}, {spy} for 3D plotting showing correlation in variables and descriptive statistical analysis based on the data array processing. Results demonstrated LaTeX scripts and graphics: 2D and 3D scatterplots, ternaries, bar charts, boxplots, zooming techniques detailing fragment of the plot, flowchart. Research novelty consists in technical approach of TeX language application for geo- logical data processing and graphical visualization. Engineering graphics by TeX was demonstrated with screenshots of the codes used for plotting.
Liquid Propellant Mass Measurement in Microgravity

Published: March 2021

The Modal Propellant Gauging (MPG) experiment has demonstrated sub-1% gauging accuracy under laboratory conditions on both flight hardware and subscale tanks. Recently, MPG was adapted for flight on Blue Origin's New Shepard vehicle and has flown twice, achieving equilibrated, zero-g surface configurations of propellant simulant at three different fill fractions. Flight data from MPG missions on New Shepard P7 and P9 show agreement between known and measured propellant levels of 0.3% for the fill fractions investigated in the present study. Two approaches for estimating zero-g propellant mass are described here. Both approaches rely on measuring shifts in modal frequencies of a tank excited by acoustic surface waves and subject to fluid mass loading by the propellant. In the first approach, shifts in the lowest mode frequency (LMF) are measured and associated with liquid fill-level changes. In the second approach, 1-g modal spectra at a range of known fill levels are used in a cross-correlation calculation to predict fill levels associated with a zero-g modal spectrum. Flight data for both approaches are consistent with finite element predictions using a simple fluid–structure interaction model. In both settled and unsettled microgravity environments, MPG meets or exceeds NASA Roadmap goals for in-space propellant mass gauging.

Information on the recent herpetological and related parasitological collections are very rarely available for Afghanistan. We examined two species of the family Agamidae, Laudakia nuristanica and Paralaudakia caucasia for the presence of the intestinal helminth fauna. Overall, we examined 13 specimens of these lizards and found three species of helminths (Abbreviata achari, Thelandros masaae, T. taylori) in a single specimen of L. nuristanica and four species (A. achari, T. baylisi, T. taylori, P. kasauli) in three specimens of P. caucasia. Here in, we present the first report on the helminth fauna from L. nuristanica, record a new helminth host for P. caucasia and three new country records for the helminth fauna of Afghanistan.

Taenia hydatigena is a tapeworm that affects herbivores in different regions of the world. Cysticercus tenuicollis (larvae of T. hydatigena), is prevalent in ruminants and pigs. In the current study, phylogenetic analysis of the published mt-CO1 gene of C. tenuicollis sheep isolates was analyzed using in-silico method and vertical and horizontal transmission at the global level by using a meta-analysis approach. A total of 82 mt-CO1 nucleotide sequences (339 bp) of C. tenuicollis sheep isolates from the NCBI database (Italy -Sardinia-, Iran, Palestine, Iraq, Finland, India and China) were used to investigate haplotype and genetic relationships. Tajima’s D (-2,2984) value was negative for the mt-CO1 sequences signifying the population expansion and/or purifying selection. The highly negative Fu’s Fs (-60,528) values determined for the sequences reflecting the existence of uncommon haplotypes. The mt-CO1 of C. tenuicollis haplotype network had 47 haplotypes arranged within a star-like configuration with a main haplotype, which encompassed 25.6 % of the total isolates. In the mt-CO1 haplotype network analyzed, there were 80.5 % unique single haplotype and highest ratio was observed in C. tenuicollis from sheep originating from Iran, followed by Sardinia, Palestine and Finland. If the current condition continues, genetic differences in T. hydatigena will be able to rise, and possible new strains and/or genotypes that may influence the host adaptation and life cycle of the parasite may emerge.
