Published: January 2021

<p>Nadaraya-Watson Estimator with kernel approach depends on two-parameter, those are kernel function and bandwidth choice. However, between the two of them, bandwidth choice gave a huge impact on the result of the estimation. By minimizing the value of Mean Square Error (MSE), Cross-Validation (CV) and Generalized Cross-Validation (GCV) gave the optimal bandwidth value. In this research, corn production was considered as the dependent variable, while the planted area, harvested area, and the fertilizer as the independent variable. The result of this research showed that Nadaraya-Watson Estimator with Generalized Cross-Validation gives a better corn production estimation with optimal bandwidth value 742392,2, with and with MSE 202583,9.</p><p><strong>Keywords</strong>: kernel, estimator Nadaraya-Watson, cross validation, generalized cross validation.</p>

BackgroundAn effective syphilis vaccine should elicit antibodies toTreponema pallidumsubsp.pallidum(T.p.pallidum) surface antigens to induce pathogen clearance through opsonophagocytosis. Although the combination of bioinformatics, structural, and functional analyses ofT.p.pallidumgenes to identify putative outer membrane proteins (OMPs) resulted in a list of potential vaccine candidates, still very little is known about whether and how transcription of these genes is regulated during infection. This knowledge gap is a limitation to vaccine design, as immunity generated to an antigen that can be down-regulated or even silenced at the transcriptional level without affecting virulence would not induce clearance of the pathogen, hence allowing disease progression.Principal findingsWe report here thattp1031, theT.p.pallidumgene encoding the putative OMP and vaccine candidate TprL is differentially expressed in severalT.p.pallidumstrains, suggesting transcriptional regulation. Experimental identification of thetprLtranscriptional start site revealed that a homopolymeric G sequence of varying length resides within thetprLpromoter and that its length affects promoter activity compatible with phase variation. Conversely, in the closely related pathogenT.p. subsp.pertenue, the agent of yaws, where a naturally-occurring deletion has eliminated thetprLpromoter region, elements necessary for protein synthesis, and part of the gene ORF,tprLtranscription level are negligible compared toT.p.pallidumstrains. Accordingly, the humoral response to TprL is absent in yaws-infected laboratory animals and patients compared to syphilis-infected subjects.ConclusionThe ability ofT.p.pallidumto stochastically varytprLexpression should be considered in any vaccine development effort that includes this antigen. The role of phase variation in contributing toT.p.pallidumantigenic diversity should be further studied.

Authors: Afshari Maryam , Karimi-Shahanjarini Akram , Khoshravesh Sahar , Besharati Fereshteh 
Published: January 2021

Objective
There is a relationship between pesticide exposure and farmworkers’ health. Well-conducted evaluations can provide an insight into how to develop and implement more effective interventions to prevent farmers and farmworkers’ exposure to pesticides. This review aimed to summarize the literature on the effectiveness of interventions to promote pesticide safety and reduce pesticide exposure among farmers and farmworkers.

Methods
A comprehensive search on PubMed, Embase, ISI Web of Science, Scopus, Science Direct, Agricola, NIOSHTIC, and Agris databases was performed to identify relevant studies published from 2000 to 2019. Randomized controlled trials (RCTs) and quasi-experimental studies assessing the effectiveness of interventions on a variety of outcomes related to pesticide exposure were considered. The searches were restricted to articles written in English. The methodological quality of included reviews was appraised using the Effective Public Health Practice Project quality assessment tool (EPHPP).

Results
The initial search led to 47912 records, 31 studies of which including nine RCTs and twenty-two quasi-experimental studies met the criteria. The majority of the included studies focused on the educational/ behavioral approach. The studies that applied this approach were effective in improving the participants’ knowledge and attitude; however, these interventions were less effective in terms of making changes in participants’ behaviors and their risk of exposure to toxic pesticides. Multifaceted interventions were moderately effective in terms of improving farmers’ and farmworkers’ behaviors and reduction in exposure to toxic pesticides. We did not find any studies that had evaluated the effectiveness of engineering/technological, and legislation/enforcement interventions.

Conclusions
Although the majority of studies were based on an educational/behavioral approach and did not assess the effect of interventions on objective measures, the results of this review highlight the significant effectiveness of educational programs and some potential key elements of these interventions. These findings may inform policymakers to develop interventions to reduce pesticide exposure among farmers and farmworkers.

ObjectiveCardiac sarcoidosis is difficult to diagnose, often requiring expensive and inconvenient advanced imaging techniques. Circulating exosomes contain genetic material, such as microRNA (miRNA), that are derived from diseased tissues and may serve as potential disease-specific biomarkers. We thus sought to determine whether circulating exosome-derived miRNA expression patterns would distinguish cardiac sarcoidosis (CS) from acute myocardial infarction (AMI).MethodsPlasma and serum samples conforming to CS, AMI or disease-free controls were procured from the Biologic Specimen and Data Repository Information Coordinating Center repository and National Jewish Health. Next generation sequencing (NGS) was performed on exosome-derived total RNA (n = 10 for each group), and miRNA expression levels were compared after normalization using housekeeping miRNA. Quality assurance measures excluded poor quality RNA samples. Differentially expressed (DE) miRNA patterns, based upon >2-fold change (p< 0.01), were established in CS compared to controls, and in CS compared to AMI. Relative expression of several DE-miRNA were validated by qRT-PCR.ResultsDespite the advanced age of the stored samples (~5–30 years), the quality of the exosome-derived miRNA was intact in ~88% of samples. Comparing plasma exosomal miRNA in CS versus controls, NGS yielded 18 DE transcripts (12 up-regulated, 6 down-regulated), including miRNA previously implicated in mechanisms of myocardial injury (miR-92, miR-21) and immune responses (miR-618, miR-27a). NGS further yielded 52 DE miRNA in serum exosomes from CS versus AMI: 5 up-regulated in CS; 47 up-regulated in AMI, including transcripts previously detected in AMI patients (miR-1-1, miR-133a, miR-208b, miR-423, miR-499). Five miRNAs with increased DE in CS included two isoforms of miR-624 and miR-144, previously reported as markers of cardiomyopathy.ConclusionsMiRNA patterns of exosomes derived from CS and AMI patients are distinct, suggesting that circulating exosomal miRNA patterns could serve as disease biomarkers. Further studies are required to establish their specificity relative to other cardiac disorders.
La entrevista política ante el sesgo audiovisual. El caso de Los desayunos de TVE (2018)
Authors: Sánchez-Castillo Sebastián , Galán-Cubillo Esteban , Gifreu-Castells Arnau 
Published: January 2021

En esta investigación se discute el posible sesgo en el desarrollo de las entrevistas televisivas a líderes políticos. Se considera que el proceso narrativo audiovisual y la puesta en escena, responsabilidad del equipo de realización, puede tener un papel decisivo en la neutralidad de las entrevistas. Se analiza el tratamiento audiovisual otorgado por la televisión pública española TVE durante el programa Los desayunos de TVE a los principales líderes políticos españoles, Pedro Sánchez, Pablo Iglesias, Albert Rivera y Mariano Rajoy y a sus colaboradores más cercanos, Adriana Lastra, Pablo Echenique, Fernando de Páramo y Fernando Martínez-Maillo, durante 2018. Durante las entrevistas analizadas se han descubierto narrativas audiovisuales dirigidas desde el equipo de realización del programa capaces de condicionar la imparcialidad de la entrevista. Se discute si el tratamiento audiovisual otorgado a cada uno de los líderes políticos es homogéneo, siendo las localizaciones y escenografías similares. Los resultados evidencian que los distintos líderes políticos no han tenido las mismas condiciones o tratamiento narrativo en la realización audiovisual, por lo que no se han enfrentado a las mismas amenazas implícitas en las preguntas que componen las entrevistas analizadas.

La investigación sobre series de televisión españolas de ficción. Un estudio de revisión crítica (1998-2020)
Authors: Mateos-Pérez Javier 
Published: January 2021

This review paper assesses academic articles published about Spanish fictional television series in scientific journals indexed in multidisciplinary databases: Web of Science (WoS), Scopus and Dialnet between 1998 and 2020. A combined quantitative and qualitative method of analysis based on the SALSA Framework was used, in order to build a systematic bibliographic review. The results showed that the most common studies were those about the representation proposed in the fictional series about certain groups or social settings. Other approaches referred to the development of television fiction genres, adaptations, as well as to audiences and how audiences had received the series. Innovative research pointed to the emerging themes of transmediality, participatory audiences, hybrid studies that explained the content from production and authorship, and feminist works. Among the gaps noted were approaches that addressed the audiovisual language and the aesthetics of television fiction as research opportunities.

Published: January 2021

Esta investigación analiza la presencia de las megaciudades iberoamericanas en los medios de comunicación digitales extranjeros en el campo específico del cambio climático. El objetivo es determinar el uso de este canal para influir en la opinión pública y en órganos de decisión. Para ello, se estudia la representación de 30 ciudades iberoamericanas en textos periodísticos relacionados con el cambio climático en los medios digitales de mayor penetración (Spiegel, 20Minuten, DR News Het Laatste Nieuws) en los países que albergan algunas de las principales instituciones de gobernanza global en asuntos medioambientales: la Convención Marco de las Naciones Unidas sobre el Cambio Climático (Alemania), el Grupo Intergubernamental de Expertos sobre el Cambio Climático (Suiza), la Agencia Europea de Medio Ambiente (Dinamarca) y la Dirección General Climate Action de la Comisión Europea (Bruselas). Los resultados evidencian el escaso protagonismo que acaparan y que la organización de grandes eventos es el mecanismo más efectivo para ocupar espacio mediático. Estas conclusiones coinciden con los resultados obtenidos para cuatro redes de ciudades: C40, Eurocities, Ciudades y Gobiernos Locales Unidos y 100 Resilient Cities.

Published: January 2021

Las ciudades europeas están sufriendo en los últimos años intensas olas de calor, favorecidas por el cambio climático. La ciudad es a la vez uno de los grandes contribuyentes a las emisiones de gases de efecto invernadero pero también un espacio clave para la adaptación y mitigación del cambio climático. Este estudio aborda de qué forma las ciudades europeas son representadas en 393 noticias periodísticas sobre las olas de calor sufridas durante los meses de junio de 2017 y 2019. Para ello se analiza la cobertura de 19 periódicos de Francia, Reino Unido, Italia, Portugal y España. Los resultados señalan que el país es la variable más determinante en la rigurosidad y profundidad del tratamiento periodístico, seguido por la orientación ideológica, la sección del medio y la autoría. Las noticias sobre las olas de calor en la ciudades europeas que tratan aspectos técnicos como el efecto Isla de Calor Urbana son las que mejor abordan las medidas estructurales de adaptación y mitigación.

Authors: Cwalina Krzysztof , Borusiewicz Andrzej , Ferrari Maude , Herrmann Ivan T. , Priekulis Juris 
Published: January 2021

AbstractMany factors influence milk production and farm development. The most critical factor determining the production is the price of sold milk and indirectly the costs connected with its production. In majority of farms, milk production is profitable. The decisive factors influencing the profitability of milk production are the balance of nutrition and ensuring the welfare of dairy herds. Equally important are the genetic characteristics of cows and proper rearing of calves. The study shows that the modernization of farms also influences the development of milk production by improving the optimization of energy use and reducing labour intensity, and overall optimization of production costs.

Published: January 2021

Abstract
In the aspect of the course and analysis of products of biomass fuels combustion in grill feed boilers, the combustion process of wheat straw and meadow hay were assessed taking into consideration conditions of SO2 emission. Different types of briquettes used in the research not only had various chemical properties but also physical properties. In the aspect of assessment of energy and organic parameters of the combustion process, the sulphur content in biomass becomes a significant factor at its energy use. Registered emission during combustion of meadow hay biomass referred to wheat biomass was for A and B type briquettes correspondingly higher by ca. 320 and 120%. Differences in SO2 emission at combustion of various biofuel forms in the aspect of the relation with the remaining combustion parameters including mainly with air flow require, however, further research that leads to development of low-emission and high-efficient biofuel combustion technologies in low-power heating devices.

Published: January 2021

Abstract
The aim of the study was to conduct an economic analysis of the possibilities of using photovoltaic (PV) installations in selected farms. Two selected online PV calculators were used for the analysis. The research included 15 farms located in the Małopolskie Province. For a PV installation estimated using Calculator 1, Hewalex, the payback period ranged from 5.5 to 7 years for the 40% subsidy option and from 9 to 11 years without the subsidy, respectively. On the other hand, the payback period estimated with the use of the SmartekDom calculator ranged from 6 to 8 years for the option with 40% subsidy. However, without the subsidy, the period ranged from 7 to even 13 years.

Authors: Łapiński Krzysztof , Sołowiej Piotr 
Published: January 2021

Abstract
In 2020, a fully automated hydropower plant was launched on the Guber River near the town of Kotkowo. The plant is operated by a master control and measurement system, which collects data to evaluate the operation of selected systems of the facility. The number and location of sensors controlling the parameters of hydroelectric systems are selected accordingly, to collect complete information from all sensors and analyze the operation of hydroelectric systems in real time. In addition, storing all the controlled parameters allows analyzing the plant’s operation over longer periods. This work presents the possibilities of this measurement system, as well as the measurement results obtained in the tested object. Analyzing the operation of the control and measurement system as well as the collected and archived data will be the foundation for a simulation model of a hydropower plant. The model will be helpful in optimizing the operation of existing hydroelectric plants in terms of energy production per unit volume of water, and in designing new ones on existing barrage.

Abstract
Understanding the perception of Sustainable Development can help to identify misconceptions surrounding the concept in order to design better education plans and public policies on this subject. Evaluating the perception of sustainability issues by focusing on the young generation as is an important proxy to imagine what the future holds for in terms of addressing sustainable development. We conducted 177 in-person interviews on a heterogeneous group of students and random volunteers in four cities in Poland to assess their perception of Sustainable Development. The vast majority (89.3%) of the respondents were familiar with the term ‘Sustainable Development’. However, part of them (57%) associated it only to the human and social development dimensions and its institutions, whereas 17.5% related it with its environmental aspects. The results supported by the literature review highlight challenges concerning the path towards a comprehensive perception of Sustainable Development and hence the achievement of the SDGs. Based on these results, we identify opportunities and incentives to bring Poland towards 2030 Agenda.

Published: January 2021

AbstractExcessive distribution of holdings is one of the most important barriers which causes that in a great part of Poland rational use of farms in impossible. This problem particularly concerns the south and east region of the country. Correct spatial distribution of lands belonging to holdings is one of the most crucial factors that enable an economically profitable activity of these farms. The aim of the paper was verification of the applicability of the prepared spatial data base, farm-land configuration of agricultural plots of the selected agricultural farms to indicate the areas of optimization of the internal transport. As a result, based on the developed spatial data base, an impact of the land configuration of agricultural plots in the investigated group of agricultural producers on organization of the field transport between the holding and agricultural plots was determined. The scope of the paper covered a vegetable producer group, which associates 5 farms that have in total 620 ha of agricultural land.
Modeling of Shear Rheological Behavior of Uncured Rubber Melt
Authors: Yang Hengxiao , Mo Qimian , Lu Hengyu , Zhang Shixun , Cao Wei , Shen Changyu 
Published: January 2021

AbstractTo describe uncured rubber melt flow, a modified Phan–Thien–Tanner (PTT) model was proposed to characterize the rheological behavior and a viscoelastic one-dimensional flow theory was established in terms of incompressible fluid. The corresponding numerical method was constructed to determine the solution. Rotational rheological experiments were conducted to validate the proposed model. The influence of the parameters in the constitutive model was investigated by comparing the calculated and experimental viscosity to determine the most suitable parameters. The uncured rubber viscosity was 3–4 orders larger than that of plastic and did not have a visible Newtonian region. Compared with the Cross-Williams-Landel-Ferry (Cross-WLF) and original PTT models, the modified PTT model can describe the rheological characteristics in the entire shear-rate region if the parameters are set correctly.
