Authors: Passos Mauro Romero Leal , Eleutério José , Bazzo Maria Luiza , Carvalho Ricardo de Souza , Nascimento Anderson Gomes do , Oliveira Junior Maurício da Silva
Published: May 2021

Introduction: Syphilis is a very old disease involved by many mysteries. From its origins to the reason why even having simple and effective diagnosis and treatment for more than half a century, it remains, in 2021, as a public health problem practically all over the world. Be it in high-developing countries as well as in developing ones. Objective: To relate and describe, with dating, by day, month and year, in a calendar model, events and important characters that involve studies and quotes about syphilis. Methods: We used the prior personal knowledge of health professionals and researchers, who have worked in the field of sexually transmitted diseases for decades, combined with the search on the Internet, often on Wikipedia and Google, about events and characters involving subjects and publications about syphilis. Results: After several analyses and researches, we listed 68 facts and characters from around the world, including several Brazilians. Conclusion: At a time (2020 and 2021) where the subject, worldwide, on a daily basis, is SARS-CoV-2/COVID-19, this unprecedented publication on facts and characters involving syphilis can be a milestone so that, in addition to technical and scientific knowledge, the academic community realizes the anthropological, sociological, and cultural wealth that involves an entity that is much more than an infectious disease, such as syphilis.

Hunting and Deforestation: A Threat to the Existence of the Niger Delta Red Colobus Monkey (Procolobus epieni)
Authors: Gbolagade Akeem Lameed , Funmilayo Lewiska Lateef
Published: April 2021

The Niger Delta in Nigeria is the largest wetland in Africa and the third largest mangrove forest in the world. The region is known for its richness in biodiversity as well as its oil and gas resources. Due to the high level of oil exploration, deforestation, hunting and insecurities in these areas, the wildlife especially endemic species like the Niger Delta red colobus becomes vulnerable to extinction. Most researches on their range have noted a significant reduction in their population and range distribution. Hence, up-to-date information on their current status is paramount to ensure proper and urgent conservation measures. Data was obtained through the use of field survey and secondary data. The species was recently discovered endemic to Niger delta region in Nigeria for about 23 years ago and recent studies observed that there has been a drastic reduction in their population and a shift in the range they formally occupied faulting this to anthropogenic activities. This study revealed that the location is under intense timber extraction and hunting and as a result, one of the location in the Apoi creek where it was reported to be present, record no species of Red colobus monkey. Only the red capped mangabey monkey (3) were sighted at the location with some evidence of alligator (10). Result also revealed that most of the communities (age ≤ 30) do not know or have seen the species. The situation at the location is exacerbated because of the level of poverty and insecurity in the areas. Going by the evidence of intense timber extraction and hunting at the location, the number of this species may have drastically reduced compared to what it was formally projected (±200 individuals). It is therefore strongly recommended that a follow up of the research is done in other location where it was reported to be present.
Barley Grain Development during Drought Stress: Current Status and Perspectives
Authors: Khodaeiaminjan Mortaza , Bergougnoux Véronique
Published: May 2021

Barley (Hordeum vulgare L.) belongs to small grain cereals that cover more than 78% of the daily calorie consumption of humans. With a prediction of 9.7 billion humans in 2050 (FAO stats) and climatic changes, the question of increasing small grain cereal’s production has become an agricultural challenge. Drought exerts a strong environmental pressure, causing large yield losses worldwide. Therefore, understanding the mechanisms responsible for grain development from the fertilization to the mature dry grain is essential to understand how drought can affect this developmental program. In this book chapter, we present the physiological, molecular and hormonal regulation of barley grain development. In a second part, we describe the consequences of drought at different stage of barley development, with a special focus on the reproductive phase. Finally, in the last part, we present the different methods used to decipher new genetic information related to drought-tolerance. All this knowledge contributes to understanding the tolerance mechanisms of barley and to developing breeding strategies aiming to bring about new varieties with sustained yield in harsh conditions.
Diffraction Grating Groove Metrology Using AFM and STM
Authors: I. Goray Leonid
Published: May 2021

AFM & STM metrology has been around for a long time, and especially intense since it has been awarded by the Nobel Prize in Physics in 1986. Since then, many AFM & STM groove profile measurements on surface relief diffraction gratings have been presented. However, a wide review of the results of the use of AFM & STM methods for groove metrology of various surface relief gratings has not really been undertaken. The following problems are discussed in this chapter: the cantilever tip deconvolution, geometry, and radius; groove shapes and abrupt groove slopes; roughness; PSD functions; etc. Also, the author demonstrates comparisons with other widely-used metrology techniques and examples of AFM & STM data of bulk, coated, and multilayer-coated ruled, or holographic, or lithographic gratings having realistic groove profiles. These gratings were chosen because high quality efficiency data exists, in particular, for space gratings or/and X-ray gratings characterized by synchrotron radiation sources; and their groove profiles, together with random nanoroughness, were measured by AFM or STM to be included in rigorous efficiency and scattered light intensity calculus. In the present chapter, both the earlier published results and the recent, non-published yet results are described and discussed.

Doping is a technique that makes it possible to incorporate substitutional ions into the crystalline structure of materials, generating exciting properties. This book chapter will comment on the transition metals (TM) doped nanocrystals (NCs) and how doping and concentration influence applications and biocompatibility. In the NCs doped with TM, there is a strong interaction of sp-d exchange between the NCs’ charge carriers and the unpaired electrons of the MT, generating new and exciting properties. These doped NCs can be nanopowders or be embedded in glass matrices, depending on the application of interest. Therefore, we show the group results of synthesis, characterization, and applications of iron or copper-doped ZnO nanopowders and chromium-doped Bi2S3, nickel-doped ZnTe, and manganese-doped CdTe quantum dots in the glass matrices.
Another puzzle piece in the systematics of the chewing louse genus Myrsidea, with a description of a new genus Apomyrsidea
Authors: Kolencik Stanislav , Sychra Oldřich , Allen Julie M.
Published: May 2021

A new avian chewing louse genus Apomyrsidea gen. nov. is described based on species parasitizing birds in the family Formicariidae. Diagnostic characteristics and phylogenetic analyses were used to evaluate and confirm the generic status and merit its recognition as unique and different from Myrsidea Waterston, 1915. Three species previously belonging to the genus Myrsidea are placed in the new genus Apomyrsidea gen. nov. and are discussed: Apomyrsidea circumsternata (Valim & Weckstein, 2013) gen. et comb. nov., Apomyrsidea isacantha (Valim & Weckstein, 2013) gen. et comb. nov. and Apomyrsidea klimesi (Sychra in Sychra et al., 2006) gen. et comb. nov.

O presente artigo tem como finalidade analisar a noção de "vítima" e os usos do conceito de "genocídio" envolvendo armênios e azerbaijanos na guerra de Nagorno-Karabakh. O objetivo é compreender como ambos os povos mobilizam essas noções de forma a sustentar suas reivindicações políticas sobre o território em questão e deslegitimar as aspirações do outro. Nesse sentido, é crucial compreender os usos políticos dos massacres e genocídios na tentativa de angariar apoio internacional para suas causas. Para tanto, vamos analisar posicionamentos de lideranças armênias e azerbaijanas sobre o conflito descongelado em setembro de 2020
Uma genealogia das empresas militares e de segurança privada: a trajetória da empresa DynCorp frente à formação do “mercado da força” nos Estados Unidos
Authors: Paoliello Tomaz Oliveira
Published: April 2021

As empresas militares e de segurança privada (EMSP) são um tipo de ator emergente nos debates a respeito dos conflitos contemporâneos, principalmente por conta de sua grande participação ao lado das tropas dos EUA nas Guerras do Afeganistão e do Iraque. A literatura sobre o tema em geral reagiu ao surgimento e crescimento do chamado “mercado da força”, identificando o que seria um momento de gênese dessas companhias, o final da Guerra Fria ou o pós 11 de setembro. Apesar disso, ao longo do século XX, é possível identificar nos Estados Unidos um conjunto de transformações nos procedimentos militares, nas tecnologias, nas normas que regularam a terceirização e na atuação dos atores privados que conformaram o atual estado do mercado para serviços militares privados e que tornaram possível a explosão desse fenômeno a partir dos anos 1990. A opção por uma genealogia, produzida através da reconstituição do desenvolvimento da empresa DynCorp, desde suas origens no pós-Segunda Guerra Mundial até a sua participação na Guerra do Iraque, busca indicar que o atual mercado para EMSP emerge a partir de adaptações de longo prazo das empresas, e de seu principal cliente, o governo dos EUA. A associação entre as EMSP e outros atores e setores econômicos indica uma dimensão econômica dos conflitos contemporâneos relacionada não apenas aos seus fins, mas também aos meios disponíveis.

In the framework of asset management, the effectiveness of an integrated process that manages reliability and maintenance should be adequately and timely evaluated based on a thorough analysis of a series of contributing factors, which should respond entirely to the result of maintenance activities on the performance of assets that make up the production process. According to the above, then arises the motivation for the design and application of tools to determine the effectiveness of such activities in asset management, understanding the latter as a holistic process that involves a diversity of functions and areas within an organization
DYNAMIC CHARACTERISTICS OF NON-SMOOTH SUSPENSION SYSTEM UNDER FRACTIONAL-ORDER DISPLACEMENT FEEDBACK
Authors: ZHANG JIANCHAO , Chen Zhan , Wang Jun , Hu Yufei
Published: May 2021

Vehicle suspension systems generally have non-smooth factors, such as clearances, collision, and constraint. The bad dynamic behaviors caused by these non-smooth factors have not been controlled effectively, thus influencing the driving performance and riding comfort of vehicles. To explore the dynamic characteristics of non-smooth suspension systems for controlling the bad dynamic behaviors, an approximate analytical solution to the response of a two-degree of freedom nonlinear suspension system, which has a fractional-order displacement feedback under harmonic excitation, was deduced by the Krylov–Bogoliubov (KB) method. This analytical solution was verified by the numerical solution of the suspension system. Moreover, the response of the suspension system with fractional-order displacement feedback control was compared with those of the systems without feedback control and traditional integer-order control. The influences of the main parameters of the system on the dynamic suspension characteristics were analyzed thoroughly. Finally, the stability of the suspension system was analyzed by plotting the maximum Lyapunov index diagram. Results show that compared with the systems without feedback control and with traditional integer-order control, the nonlinear suspension system with fractional-order displacement feedback control can significantly improve vehicle acceleration, the dynamic deflection of the suspension, and the displacement of the vehicle body. Controlling the nonlinear stiffness coefficient of the suspension system within 103–106 is conducive to decreasing the dynamic deflection of the suspension system of vehicles, while increasing the fractional-order control coefficient and the fractional order is beneficial to controlling the dynamic deflection of the suspension system and the displacement of the vehicle body. Conclusions obtained in the study can provide unique references for the optimal design and control of nonlinear suspension systems with fractional-order displacement feedback control.

This article presents the results of the experimental tests carried out on a polyurethane hyperelastic adhesive. The Mooney-Rivlin, Ogden and Yeoh models were analyzed between others, with different order and parameters using the finite element method and the Ansys V17.1 package, with the aim of evaluating the convergence of a general hyperelastic model, to subsequently manufacture specimens and perform experimental uniaxial stress tests. The information obtained from the tests was supplied to a curve fitting model for several hyperelastic models, seeking to obtain a correlation between these tests. New analyzes were performed with the finite element method with the materials considered and the curves adjusted. The results were studied and the numerical hyperelastic model closest to reality was selected, observing that the 1st order Yeoh model presented significant deviations between -30% to 60% in the experimental stiffness, the 3rd order Yeoh model presented deviations of -5% to -30%, while Ogden models of 1st and 3rd order presented deviations of -3.5% to 25% and -3% to 20%, before approaching the critical load, where the model of Ogden of 1st order presented a deviation of 0.66% and that of 3rd order of -3.59%. The 2 parameter Mooney-Rivlin model presents a deviation of 3.9% when it approaches the critical load, but values from -2.04% to 15% during the development of the stress test, so that model proved to be the most appropriate to analyze the material investigated in this work.

COST EFFECTIVE METHOD FOR THE STUDY OF THE SHORT-CIRCUIT BEHAVIOUR OF AN ELECTRICAL RESISTOR
Authors: GARCÍA MENÉNDEZ DAVID , LUMBRERAS IGLESIAS CARLOS , ALONSO MENÉNDEZ MARIO , SUAREZ SIERRA ROBERTO
Published: May 2021

Electrical resistors for power lines are used worldwide as Neutral Earthing Resistors for short-circuit current reduction in power grids, and also as Filtering Resistors in combination with capacitors and inductances. The manufacturers of such resistors must certificate that they withstand the mechanical and thermal stresses imposed by the external loads, in accordance with IEC 62001 standard. Although this certification can be achieved by means of testing the resistor under working conditions, this process is both expensive and time-consuming.
In this paper it is proposed a methodology for simulating the thermal and mechanical behavior of an electrical resistor, based on Multiphysics Finite Element Analysis. The methodology has been applied for the analysis of a filtering resistor for the Ethiopia-Kenia Power Systems Interconnection.

PREDICTION FOR TOTAL MOISTURE CONTENT IN WOOD PELLETS BY NEAR INFRARED SPECTROSCOPY (NIRS)
Authors: SÁNCHEZ GATÓN MIGUEL ÁNGEL , CAMPOS LABADIE MARIA ISABEL , SEGOVIA PURAS JOSE JUAN
Published: May 2021

Mankind consumes as many fossil fuels per year as nature produced during a million years. Furthermore, energy consumption has tripled in the last 60 years, and is expected to be doubled in 2050, due to the technological and economic takeoff of large emerging powers. In light of this scenario, a change in energy policies should be aimed to promote energy efficiency and the use of sustainable energy resources, such as bioenergy, safely and environmental friendly.
Biomass fuels take a main role in the EU's energy and climate policies, aimed at reducing CO2 emissions and combating Climate Change. Quality control of biofuels and knowledge of their characteristics reach a large relevance in any industrial application based on the energy use of biofuels.
NIRS technology (near infrared spectroscopy, Near Infrared Reflectance Spectroscopy) is based on the interaction between electromagnetic radiation and material, and now is presented as an encouraging technological tool for quality testing of solid biofuels, since it is a non-destructive and much faster and cheaper analytical technique than traditional ones, which are based on current ISO standards. That interaction appears as spectral vibrations (energy absorption or absorbance) that are properly processed, allowing to measure the most important physical-chemical properties of solid biofuels in a fast, simple and non-destructive way.
Wood pellet is the highest quality solid biofuel in the current biomass market, which is regulated by ENplus® certification scheme in the European-wide, ensuring the quality of product to consumers. Low heating value is the most important parameter of solid biofuel, and is strongly linked to total moisture content, so the control of moisture is key factor during pelletizing process.
The original research carried out in this work allows to present the development of a NIRS prediction model for total moisture in wood pellets, in the range of values of 5 – 10 %, providing a much faster and more automated methodology for product quality control, both in production plants of wood pellets and in power plants with wood pellets as fuel.

Des critiques féministes de l’hétérosexualité : contribution et limites des théorisations lesbiennes et queers1
Authors: Mayer Stéphanie
Published: May 2021

L’hétérosexualité fait l’objet de critiques à partir de perspectives féministes, lesbiennes et queers. L’objectif de l’auteure est de souligner la contribution théorique des lesbiennes et des queers à ces débats, tout en relevant le caractère équivoque de cet héritage pour les hétérosexuelles. La démonstration repose sur une analyse critique de discours concernant l’hétérosexualité depuis 50 ans. Divisé en trois parties, l’article propose : 1) une présentation des problématisations lesbiennes féministes, lesbiennes radicales et queers de l’hétérosexualité; 2) une réflexion sur les rapports entretenus par les féministes hétérosexuelles avec ces critiques; 3) une discussion sur l’utilité des moyens proposés à l’encontre des effets négatifs de l’hétérosexualité sur les femmes et sur la nécessité de l’action politique ancrée dans la quotidienneté des rapports intimes pour plus de justice entre les partenaires.
Les identités lesbiennes et les positionnements queers comme stratégies politiques : perspectives et transformations dans l’espace montréalais1
Authors: Chanady Tara
Published: May 2021

À travers une perspective phénoménologique mobilisant des entrevues marchées, l’auteure explore différentes significations associées aux positionnalités lesbiennes et queers dans le contexte montréalais. Son approche se base sur le partage expérientiel de participantes lesbiennes, bi et queers aux vécus diversifiés (dont l’âge et le statut migratoire) pour articuler des questionnements identitaires autour des questions spatiales. L’expérience de l’entrevue marchée mène parfois vers des explorations d’espaces communautaires et la mise en avant de politiques identitaires, parfois vers un mouvement associé au flânage et à une conception fluide de la sexualité. Les trajectoires socioculturelles lesbienne et queer examinées par l’auteure présente une lecture de l’orientation sexuelle à la fois comme vécu personnel et comme positionnalité politique, et font écho à la spécificité du territoire montréalais.
Les conditions et les « scènes » de visibilité médiatique lesbienne et féministe : l’atelier de photographie Plessisgraphe des années 70 et 801

Published: May 2021

Quelles étaient certaines des conditions de visibilité lesbienne à Montréal pendant les années 70 et 80 au croisement de la Révolution tranquille, de l’émergence de la libération lesbienne et gaie ainsi que de la deuxième vague féministe? Cet article explore la problématique de la visibilité au coeur de la pensée et de l’expérience lesbienne et des femmesqueer, se basant sur le cas de l’atelier de photographie Plessisgraphe. En ayant recours aux ressources épistémologiques et méthodologiques des études de la culture visuelle, l’auteure se penche sur les pratiques de deux photographes lesbiennes-féministes qui ont contribué à la visibilité lesbienne au sein d’un réseau culturel et médiatique féministe montréalais.
De la lutte contre le racisme au soutien aux demandeuses d’asile lesbiennes : expériences lesbiennes féministes en France depuis la fin des années 90
Authors: Falquet Jules
Published: May 2021

L’auteure propose de rendre visibles et de relire certaines expériences de lesbiennes féministes racisées et blanches depuis la fin des années 90, devant le racisme du mouvement lesbien, puis à l’égard du durcissement nationaliste des politiques migratoires françaises, en s’appuyant sur le concept d’homonationalisme de Jasbir K. Puar (2007). Le point de départ se situe dans l’expérience personnelle de l’auteure, engagée comme activiste et en tant qu’universitaire, sur le thème du genre et du lesbianisme dans la migration, et partie prenante de plusieurs initiatives pionnières dans le domaine. Adoptant une perspective épistémologique qui met en valeur l’importance du point de vue situé, l’auteure insiste également sur le rôle central de différentes lesbiennes racisées et prolétarisées.

L’auteure distingue la première période, de 1999 à 2004, pendant laquelle prédomine la dénonciation du racisme, au sein du mouvement lesbien lui-même, sous la houlette d’un groupe de lesbiennes racisées qui défend fermement, pour la première fois, l’organisation autonome, c’est-à-dire la non-mixité de race. De 2005 à 2010, un virage s’opère vers des luttes contre l’hétérosexisme des politiques migratoires (de plus en plus restrictives), et la migration des lesbiennes commence à être visibilisée au travers d’initiatives plutôt mixtes et, en partie, universitaires. Enfin, l’auteure revient sur le concept d’« homonationalisme » et mobilise les concepts d’« hétérocirculation » des femmes et de « lesbonationalisme » pour décrire la situation actuelle et les modes d’agir des nouveaux groupes.
Seduction, Sharing Stories, and Borderlinking in Co-Constructed Narratives
Authors: Voela Angie , Esin Cigdem , Achan Jennifer
Published: May 2021

Drawing on a co-constructed autobiographical narrative as our example, we explore the resonances of Catherine Kohler Reissman’s concept of seduction with Bracha Lichtenberg Ettinger’s concept of matrixial borderlinking. Borderlinking between theoretical domains, rather than comparisons or juxtaposition, brings forth potentialities and expands the theorization of feminine subjectivities in much the same way as co-constructed narratives celebrate the we without obliterating the I.
Individuality and Continuity in Narrating across Generations
Authors: Skultans Vieda
Published: May 2021

This article explores the commonalities of structure in the life histories of a mother and her daughter. I argue that sharing the same story does not preclude the existence of a strong and distinctive sense of self. Agency and selfhood are intimately connected with interpretation and the pursuit of understanding. In order to illuminate this relationship, I draw upon ideas of musical form and interpretation that suggest how this might come about.
Narrative Relations and Associations: Catherine Kohler Riessman’s Research Dialogism
Authors: Esin Cigdem , Squire Corinne
Published: May 2021

In this paper, Esin and Squire provide their individual and collective reflections on the influence of Catherine Kohler Riessman’s dialogical approach in research. Each researcher reinterpreted the dialogism in Riessman’s approach in their own work, focusing on differing elements of it. While Esin examines her experience of relationality, reflexivity, and positionality in her work, Squire discusses her adoption of the approach to develop methodological interdisciplinarity in social science research. The authors then reflect on their dialogue in researching multimodal narratives, historical positioning in and beyond narratives, and power relations in the context of research.
Looking Back, Looking Forward
Authors: Riessman Catherine Kohler
Published: May 2021

Responding to the honor of the festschrift, I name and honour those who guided me, especially my mentor, Elliot Mishler. I describe a path from initial fascination with the idea of a “story” to my subsequent work that expanded the study of narrative in the human sciences. Efforts to understand how individuals interpreted—made sense of—events and situations that had interrupted their lives led me to discoveries about narrative form, apparent only after close textual interactional analysis. Recently, the appeal of narrative has mushroomed; I urge scholars not to lose sight of features that distinguish it from other forms of discourse.
PUBLIC HISTORY: AN EFFORT TO INCREASE INDONESIAN HISTORICAL CONSCIOUSNESS DURING COVID-19 PANDEMI
Authors: Abdurakhman Abdurakhman , Rahman Syahidah Sumayyah
Published: May 2021

The writing of public history has become one of the methods of history that have developed and are in great demand. The difference between history in general and public history is the selection of groups that are used as research sources. Through this research, the author find that public history can be used as a way to raise historical consciousness in Indonesia. Historical Consciousness relates to thinking of ourself in time as historical beings and being aware of belonging to a specific group with a particular history and identity. The current global pandemic presents a challenge for historians. Documenting the history at the time the event was still taking place was a challenge in itself since no one knew how the end of the event was written. Public history has been widely used in European countries to record daily life and events that occurred in society during the pandemic. The historical sources collected from the public will play an important role on writing the historical event and also as a lesson in the future. The method used in this paper is a historical method consisting of 4 stages, namely heuristics, source criticism, interpretation, and then historiography.
SCHIZOPHRENIC AUDITORY AND VISUAL HALLUCINATIONS IN THE POEM “DU PYEON-EUI JUGEUM”
Authors: Istirahmah Nadira , Panggabean Lovelyta , Latifah Eva
Published: May 2021

Although the mental health issue is often brought up as an interesting discussion topic for these past few years, negative stigmas towards people with psychological disorders, especially schizophrenia, still exist within society. However, by expressing self-acceptance and innermost thoughts in her poetry, Choi Seung-Ja succeeded in breaking the stigmas and lived her life as a schizophrenic poet. Based on this fact, this research aims to unfold the meaning of the auditory and visual hallucinations shown in Choi Seung-Ja’s poem entitled “Du Pyeon-eui Jugeum” and to explain the motives behind the creation of the schizophrenic aspects. In order to achieve these goals, this research was carried out in three stages: reading stage; reconciliation stage; interpretation stage, through expressive psycho-literary approach. The result was obtained by associating the poem’s sensory imageries with theories related to schizophrenia disorder, the poet’s life history, and historical events. The findings show that “Du Pyeon-eui Jugeum” reflects Choi Seung-Ja’s notion which doesn’t portray death merely as a beginning of destruction but also as a gateway to self-restoration and catharsis. Furthermore, hallucinations were used not only to develop the poem’s imageries but were also used to project the feelings and the external aspects of the poet.

Nursing assistants (NAs) working in nursing homes (NHs) are at higher risk for work-related musculoskeletal symptoms (WRMSs) than their counterparts working in other health care settings. Worldwide, NAs have ranked shoulders in the top three body parts at risk of WRMSs. However, factors associated with their shoulder WRMSs are currently unknown. The aim of this study was to identify these associated risk factors among NAs working in NHs. 440 NAs from 47 nursing homes (with 60–90% response rate from each nursing home), recruited by convenience sampling, participated in this cross-sectional study in 2014–2015. A validated and reliable questionnaire was used for data collection. Information on demographic, job content questionnaire (JCQ), perceived physical exertion (PE), workstyle, ergonomic and manual handling knowledge and other work-related factors was collected using a self-administered questionnaire. 53% of the participants reported experiencing with WRMSs in their shoulders. Nine associated factors of shoulder WRMSs were identified using bivariate analysis. With the adjustment of age and gender using multivariable logistic regression, body mass index (OR = .931, 95% CI [.874–.991]), job title of health workers (OR = 2.72, 95% CI [1.18–6.25]) and workstyle-working through pain (OR = 1.06, 95% CI [1.01–1.11]) remained as predictors. Effort should be directed at integrating “workstyle intervention” into lifestyle physical activity training for NAs.

Background

Dragonflies and damselflies (Odonata) are important components in biomonitoring due to their amphibiotic lifecycle and specific habitat requirements. They are charismatic and popular insects, but can be challenging to identify despite large size and often distinct coloration, especially the immature stages. DNA-based assessment tools rely on validated DNA barcode reference libraries evaluated in a supraregional context to minimize taxonomic incongruence and identification mismatches.

Methods

This study reports on findings from the analysis of the most comprehensive DNA barcode dataset for Central European Odonata to date, with 103 out of 145 recorded European species included and publicly deposited in the Barcode of Life Data System (BOLD). The complete dataset includes 697 specimens (548 adults, 108 larvae) from 274 localities in 16 countries with a geographic emphasis on Central Europe. We used BOLD to generate sequence divergence metrics and to examine the taxonomic composition of the DNA barcode clusters within the dataset and in comparison with all data on BOLD.

Results

Over 88% of the species included can be readily identified using their DNA barcodes and the reference dataset provided. Considering the complete European dataset, unambiguous identification is hampered in 12 species due to weak mitochondrial differentiation and partial haplotype sharing. However, considering the known species distributions only two groups of five species possibly co-occur, leading to an unambiguous identification of more than 95% of the analysed Odonata via DNA barcoding in real applications. The cases of small interspecific genetic distances and the observed deep intraspecific variation inCordulia aenea(Linnaeus, 1758) are discussed in detail and the corresponding taxa in the public reference database are highlighted. They should be considered in future applications of DNA barcoding and metabarcoding and represent interesting evolutionary biological questions, which call for in depth analyses of the involved taxa throughout their distribution ranges.
De la despoblación a la repoblación rural de las montañas
Authors: Palacio Sara
Published: April 2021

La despoblación rural ha modificado profundamente los paisajes de montaña europeos, con importantes cambios en el funcionamiento de los ecosistemas, su biodiversidad y su dinámica. En ocasiones, estos cambios se traducen en importantes problemas ambientales. La recuperación de los usos tradicionales del territorio, apoyada en una repoblación del medio rural de montaña, podría ser una solución sostenible a estos problemas. De hecho, existe una creciente demanda social de retorno a la vida rural. En las últimas décadas, diversas iniciativas sociales se han abierto paso para lograr una lenta repoblación de los núcleos rurales de montaña en nuestro país. No obstante, los estudios ecológicos destinados a generar conocimiento que permita guiar una repoblación rural sostenible son escasos. Tampoco se conoce en qué medida el incipiente proceso de repoblación rural está impactando sobre los ecosistemas de montaña. Pero la repoblación rural es una realidad que merece ser estudiada y guiada desde el conocimiento ecológico. Esta contribución es una llamada para cubrir un vacío de conocimiento que, de seguir así, puede afectar más aún a esas zonas de montaña en las próximas décadas.
Efectos del cambio climático en la vegetación de la alta montaña de Tenerife
Authors: Martín Esquivel Jose Luis , Marrero-Gómez Manuel V. , González Mancebo Juana M.
Published: April 2021

La vegetación de alta montaña de Tenerife está formada actualmente por un matorral ralo con retama (Spartocytisus supranubius) y rosalillo (Pterocephalus lasiospermum) como especies dominantes. Este ecosistema está sufriendo un calentamiento importante que está teniendo consecuencias en la estructura y composición de la vegetación. En efecto, mientras especies como la retama se encuentran en declive, otras como el rosalillo se expanden cada vez más. Al efecto de las temperaturas hay que unir el de la herbivoría, que en algunos casos se ve amplificado por las consecuencias del cambio climático, de modo que, igual que hay diferencias en la palatabiidad de las especies a los herbívoros, se pueden identificar especies a las que el cambio climático favorece (ganadores del cambio climático) y especies a las que el cambio climático perjudica (perdedores del cambio climático). Todo ello está modificando la vegetación de forma ostensible, con la aparición de comunidades vegetales cada vez más diferenciadas respecto a las definidas para este ecosistema.

Published: May 2021

The objective of the present study was to specify a model for the study of the relationships between agenda effects, framing, priming and melding. A documentary, retrospective and exploratory study was conducted with a selection of sources indexed to international repositories, considering the year of publication and the keyword algorithm. Differences were evidenced between the published literature and the qualifications of judges who are experts in the field, although the design of the work limited these findings to the search algorithm, suggesting the extension of the study to the indicative logic of credibility and verifiability of the information disseminated in the media.

Authors: Onojake M. Chukunedum , Waka T. Angela
Published: May 2021

The petroleum industry includes the global processes of exploration, extraction, refining, transportation and marketing of natural gas, crude oil and refined petroleum products. The oil industry demands more sophisticated methods for the exploitation of petroleum. As a result, the use of oil field chemicals is becoming increasingly important and has received much attention in recent years due to the vast role they play in the recovery of hydrocarbons which has enormous  commercial benefits. The three main sectors of the petroleum industry are Upstream, Midstream and Downstream. The Upstream deals with exploration and the subsequent production (drilling of exploration wells to recover oil and gas). In the Midstream sector, petroleum produced is transported through pipelines as natural gas, crude oil, and natural gas liquids. Downstream sector is basically involved in the processing of the raw materials obtained from the Upstream sector. The operations comprises of refining of crude oil, processing and purifying of natural gas. Oil field chemicals offers exceptional applications in these sectors with wide range of applications in operations such as improved oil recovery, drilling optimization, corrosion protection, mud loss prevention, drilling fluid stabilization in high pressure and high temperature environment, and many others. Application of a wide range of oilfield chemicals is therefore essential to rectify issues and concerns which may arise from oil and gas operational activities. This review intends to highlight some of the oil field chemicals and  their positive applications in the oil and gas Industries.

Published: May 2021

This paper explores the use of Igbo proverbs in selected folklorist Mike Ejeagah’s folk songs-Omekagụ (one who behaves like a lion) and Ụwa Mgbede Ka Mma (life of serenity is beautiful). Mike Ejeagha, the folk artist is known for his ingenuity in fusing tales rich in proverbs within his folk songs. This paper argues that the contextual meanings of the exemplary proverbs in the selected songs are derived from the content of the tales in the selected songs. The researcher will do a textual analysis of the proverbs in the songs while asserting that the meanings of the proverbs are embodied in the storyline. In analyzing the meanings of the proverbs in the songs, this research affirms the place of proverbs in the socio cultural environment of the Igbo people of South Eastern Nigeria and it finally shows that Mike Ejeagaha’s folk songs can be an agent of cultural and historical storage of the Igbo culture.

Vocal for local’ the slogan for Atma Nirbhar Bharat Abhiyan accentuate self reliance by bringing the local products to the global arena. Indian agrarian sector provide huge scope for demand driven agricultural research in this context. Agri Business Incubation centres institutionalised by ICAR envisage product development, promulgation of IP protection and technology commercialisation. Each of these centres focus to reinforce the linkage between the research institutes and industries in their mandated areas. Accordingly, the network of Agri Business Incubators(ABI) established by Kerala Agricultural University (KAU) covers diverse crops under the agriculture sector with special emphasis on value addition and market linkage. The present paper depicts the agribusiness ecosystem of Kerala in general and the role of KAU-ABI in reviving the ecosystem in particular. The beneficiaries who were facilitated through KAU-ABI during 2017-2020 were selected for the analysis. Primary and secondary data were collected and ex-post facto research design based on purposive sampling was followed. Performance indicators such as preference for training, extent of support received, transfer of technology, legitimisation and upgradation of the enterprises were selected for the analysis. The results indicated that KAU-ABI strengthened the linkage between entrepreneurs, various facilitators and key investors in the entrepreneurial ecosystem. It also created entry points in the agricultural value chains to accelerate economic growth for the agripreneurs.
