Published: August 2020

The buds of Populus balsamifera L. are a source of biologically active compounds, among which flavonoids are considered major. The aim of our study is to determine the optimal method for extraction by barothermal method, ethanol and supercritical carbon dioxide, isolation and purification of flavonoid components of Populus balsamifera L. buds. The article presents the results of a study of barothermic, alcohol extraction and extraction by liquid carbon dioxide of the raw materials of the Populus balsamifera L. buds. All three methods allow the extraction of biologically active flavonoids. Moreover, the completeness of the extraction of the flavonoids of the Populus balsamifera L. buds is achieved by the barothermic method. In turn, the extraction by liquid carbon dioxide allows the targeted extraction of pinostrobin with a high content in sum of Populus balsamifera L. buds substances. During chromatographic separation using petroleum ether : ethyl acetate as eluents, yield of flavonoids pinostrobin, tectochrysine, pinocembrin and chrysin is comparatively higher than when using other systems as eluents. Thus, for the preparative production of biologically active flavonoids pinostrobin, tectochrysine, pinocembrin and chrysin, we have determined the optimal conditions for extraction by the barothermic method and chromatographic separation of the sum of substances of Populus balsamifera L. buds.

Published: August 2020

The results of studies on the effect of negative temperatures (the process of freezing - defrosting) on aqueous solutions of preparations obtained by carboxymethylation of waste products from the processing of plant materials (oat flower films, buckwheat husks, poplar leaf litter) are presented. The purpose of this paper is to study the effect of storage conditions of solutions of carboxymethylated plant materials at low temperatures on their growth-regulating properties. The properties of aqueous solutions of carboxymethylated sunflower husks, oat flowering films, poplar leaf litter with a two-fold freeze-thawing cycle for defining growth-regulating ability were studied.
It was established that all the studied samples retain their growth-regulating ability with respect to Ivory oats and Omskaya 36 wheat. Freezing and thawing processes enhance their growth-regulating effect. The studied biological products can increase seed germination and enhance the growth processes of the studied crops. For oats, the germination rate increased by 5–10%, the length of the root increased by 1.6–3.2 times, and the stem by 2.5–4.8 times as compared with the control. For wheat, the germination rate increased by 10–18%, the root length increased by 1.5–2.9 times, and the stem by 2.0–4.8 times as compared with the control.

Os Planos Diretores Municipais têm papel fundamental na gestão de riscos e desastres. Este artigo apresenta estudo da Política Nacional de Proteção e Defesa Civil – PNPDEC (Lei nº12.608/12) e da Política Urbana relacionando redução de riscos de desastres e planejamento urbano, tendo o município de São José dos Campos-SP como estudo de caso. O artigo relaciona o macrozoneamento urbano, definido nos Planos Diretores, com as áreas de risco mapeadas no município. Observou-se que as áreas de risco se encontram tanto na área urbana quanto na área rural, porém especialmente em núcleos informais de habitação, motivo pelo qual as moradias não seguem padrões mínimos de construção e urbanismo, o que aumenta o risco de deslizamentos e inundações. Embora haja avanço nos Planos Diretores e na política de redução de riscos de desastres em São José dos Campos, observa-se que a questão de desastres está também relacionada ao processo de urbanização acelerado, falta de fiscalização pelo poder público, déficit habitacional e, carência de políticas sociais que atendam pessoas com recursos insuficientes para a construção de moradias seguras e/ou fora de áreas de risco.
DESEMBOLSOS DO BNDES AO SETOR SUCROENERGÉTICO E OS PROCESSOS DE HOMOGENEIZAÇÃO TERRITORIAL ENERGÉTICO NO ESTADO DE SÃO PAULO

Published: August 2020

A relação mercado e Estado no setor sucroenergético se modifica diante da inserção e padrão de importância que assume na economia doméstica e mundial, em períodos de maior ou menor intervenção estatal. Uma articulação (Estado-mercado) que vai delineando as formas de expansão e retração espacial, bem como estruturando padrões de concentração da propriedade e uso da terra, sobretudo no estado de São Paulo. Mesmo frente ao processo de desregulamentação imposto ao setor, observa-se que, dada sua posição na economia doméstica, na produção de commodities e atuação bursátil, o Estado, via BNDES, ainda disponibiliza recursos e viabiliza suas estratégias de expansão espacial e articulação financeira. Frente ao exposto, o artigo analisa os desembolsos do BNDES no estado de São Paulo, por finalidade e por município, microrregião e mesorregião, no período de 2000 a 2012, bem como seu impacto na produção e na diversidade produtiva. Verificou-se que tais processos resultam em um padrão de homogeneização territorial, compreendido como determinação das lógicas de consolidação hegemônica do agronegócio, ao aprofundar as relações mercantis e financeiras na agricultura nacional.
POLÍTICAS PÚBLICAS VOLTADAS PARA A POPULAÇÃO IDOSA: UMA AVALIAÇÃO DOS IDOSOS QUE FREQUENTAM OS CRAS DE ITUIUTABA (MG)
Authors: Candida da Silva Gonçalves Geisa , Moura Gerusa Gonçalves
Published: August 2020

A população idosa cresceu substancialmente e, para atender às novas demandas, o Estado apresenta políticas públicas voltadas para os idosos que supram suas necessidades, garantindo-lhes os serviços essenciais. O objetivo desse estudo é perceber como os idosos, que frequentam os seis Centros de Referência de Assistência Social instalados na cidade de Ituiutaba (MG), avaliam as políticas públicas voltadas para a população idosa, verificando o entendimento dos mesmos a respeito delas e indicando ações que contemplem as necessidades desta população. Para isso, foram entrevistados os idosos que participam das atividades e projetos realizados CRAS de Ituiutaba. Os resultados indicam que os entrevistados reconhecem a importância do CRAS, o excelente atendimento que recebem e a necessidade de melhoria dos espaços físicos. Há uma grande dificuldade dos idosos em entender as políticas públicas voltadas para eles, bem como quais direitos são assegurados. Outro resultado interessante é a prioridade que eles atribuem ao transporte público e ao atendimento público da saúde, evidenciando que estes são os “direitos” considerados mais importantes. Fica evidente a necessidade de mais pesquisas e ações que contribuam para a valorização dos idosos, bem como seu engajamento na sociedade e, sobretudo, a garantia de um envelhecimento com qualidade, segurança e dignidade.

Published: August 2020

Plant-Microbial Fuel Cell (PMFC) technology is a promising bioelectrochemical system that can exploit natural plant rhizodeposition to generate electricity. PMFCs can be used to simultaneously generate electricity while growing edible plants, as illustrated in this study. However, the common problem encountered for soil PMFCs is the low power output. To solve this problem, the stacking behavior of PMFCs was examined to maximize the power output of several cells. A grid of 9 PMFCs (3x3) was constructed with stainless steel and carbon fiber electrodes growing green beans (V. ungiculata spp. sesquipedalis) for stacking purposes. Stacking results have shown that too many cells connected in series will result in voltage losses, while stacking in parallel conserves voltage between cells. Stacking a maximum of 3 cells in series is acceptable based on the results, since cumulative stacking revealed that voltage reversals can reduce the overall potential of the stack if there are too many connected cells. Stack combinations were also tested, resulting in an enhanced performance upon combining series and parallel connections allowing power to be amplified and power density to be conserved. The combination of three sets of three cells in series stacked in parallel (3S-P) generated the highest power and power density (160.86 μW/m2) amongst all combinations, showing that power amplification without losses to power density are possible in PMFC stacking. Overall, proper stacking combinations have been shown to greatly affect the performance of PMFCs. It is hoped that the results of this study will contribute to the efforts of applying PMFC technology on a larger scale.
The Determination of Basal Glycemia and Glucose Tolerance Curve: The Manners of Blood Sampling
Authors: Golda Věroslav
Published: August 2020

There were analyzed the conditions under which the basal glycemia and/or glucose tolerance curve is not contaminated by stress induced changes in glycide metabolism. When the basal glycemia was monitored,blood was sampled to heparinized capillaries from retrobulbar plexus under the light ether anaesthesia or by decapitation without narcosis. The animal represented the control for itself. No differences was found in basal glycemia under the two mentioned blood sampling. In the second series of experiments glycemia was monitored in the time schedule which is used in glucose tolerance test, i.e., blood sampling was performed 30,60,120 and 180 min after the first sampling from retrobulbar plexus either under light ether anaesthesia (in 14 h starvated rats or in rats with free access to diet) or under Nembutal anaesthesia (in 14 h starvated rats). No differences were found in glycemia when two types of narcosis is compared. No signs of augmentation were detected. In the last series when blood sampling was taken in two sec intervals, time dependent augmentation of stress glucose elevation was found. The augmentation was more expressed in the rats with free access to diet than in starvated animals.

Authors: Maffly-Kipp Joseph , Flanagan Patricia , Kim Jinhyung , Schlegel Rebecca J. , Vess Matthew , Hicks Joshua A.
Published: August 2020

Introduction: Previous research demonstrates that perceived authenticity is positively associated with psychological health and security in the face of threats. The current research extends this work by testing whether perceived authenticity promotes recovery from the negative mental health consequences of collective trauma (e.g., a natural disaster).

Methods: We recruited a sample of undergraduates (N = 570), many of whom reported direct or indirect exposure to Hurricane Harvey, to complete surveys at two time points. We assessed exposure to the disaster, acute stress, post-traumatic stress, coping, and authenticity twice, once approximately 1 month after Hurricane Harvey (Time 1) and again approximately 9 weeks after Hurricane Harvey (Time 2).

Results: We employed multilevel modelling to explore whether authenticity would aid in recovery from collective trauma. Results showed that perceived authentic living at Time 1 predicted a variety of indicators of stress related to the hurricane at Time 2. Specifically, those participants who reported low authentic living at Time 1 reported greater levels of stress at Time 2, compared to individuals who reported higher levels of authentic living. Importantly, these effects remained even when controlling for known predictors of stress (e.g., levels of stress at Time 1 and coping strategies).

Discussion: Findings provide preliminary insight into authenticity as a part of a likely larger network of interrelated psychosocial qualities that have the potential to help one navigate recovery from trauma.
Green Apple e-Cigarette Flavorant Farnesene Triggers Reward-Related Behavior by Promoting High-Sensitivity nAChRs in the Ventral Tegmental Area
Authors: Cooper Skylar Y. , Akers Austin T. , Henderson Brandon J.
Published: August 2020

While combustible cigarette smoking has declined, the use of electronic nicotine delivery systems (ENDS) has increased. ENDS are popular among adolescents, and chemical flavorants are an increasing concern because of the growing use of zero-nicotine flavored e-liquids. Despite this, little is known regarding the effects of ENDS flavorants on vaping-related behavior. Following previous studies demonstrating the green apple flavorant, farnesol, enhances nicotine reward and exhibits rewarding properties without nicotine, this work focuses on the green apple flavorant, farnesene, for its impact on vaping-related behaviors. Using adult C57BL/6J mice, genetically modified to contain fluorescent nicotinic acetylcholine receptors (nAChRs), and farnesene doses of 0.1, 1.0, and 10 mg/kg, we observed farnesene-alone produces reward-related behavior in both male and female mice. We then performed whole-cell patch-clamp electrophysiology and observed farnesene-induced inward currents in ventral tegmental area (VTA) putative dopamine (pDA) neurons that were blocked by the nAChR antagonist, DhβE. While the amplitudes of farnesene-induced currents are ∼30% of nicotine’s efficacy, this indicates the potential for some ENDS flavorants to stimulate nAChR function. Additionally, farnesene enhances nicotine’s potency for activating nAChRs on VTA dopamine neurons. This may be because of changes in nAChR stoichiometry as our data suggest a shift toward high-sensitivity α4β2 nAChRs. Consequently, these data show that the green apple flavorant, farnesene, causes reward-related behavior without nicotine through changes in nAChR stoichiometry that results in an enhanced effect of nicotine on VTA dopamine neurons. These results demonstrate the importance of future investigations into ENDS flavorants and their effects on vaping-related behaviors.
Differential Modulation of Ventral Tegmental Area Circuits by the Nociceptin/Orphanin FQ System

Published: August 2020

The neuropeptide nociceptin/orphanin FQ (N/OFQ) can be released by stressors and is associated with disorders of emotion regulation and reward processing. N/OFQ and its receptor, NOP, are enriched in dopaminergic pathways, and intra-ventricular agonist delivery decreases dopamine levels in the dorsal striatum, nucleus accumbens (NAc), and ventral tegmental area (VTA). We used whole-cell electrophysiology in acute rat midbrain slices to investigate synaptic actions of N/OFQ. N/OFQ was primarily inhibitory, causing outward currents in both immunocytochemically identified dopaminergic (tyrosine hydroxylase positive (TH(+))) and non-dopaminergic (TH(–)) VTA neurons; effect at 1 μm: 20 ± 4 pA. Surprisingly, this effect was mediated by augmentation of postsynaptic GABAAR currents, unlike the substantia nigra pars compacta (SNc), where the N/OFQ-induced outward currents were K+channel dependent. A smaller population, 17% of all VTA neurons, responded to low concentrations of N/OFQ with inward currents (10 nm: −11 ± 2 pA). Following 100 nmN/OFQ, the response to a second N/OFQ application was markedly diminished in VTA neurons (14 ± 10% of first response) but not in SNc neurons (90 ± 20% of first response). N/OFQ generated outward currents in medial prefrontal cortex (mPFC)-projecting VTA neurons, but inward currents in a subset of posterior anterior cingulate cortex (pACC)-projecting VTA neurons. While N/OFQ inhibited NAc-projecting VTA cell bodies, it had little effect on electrically or optogenetically evoked terminal dopamine release in the NAc measuredex vivowith fast scan cyclic voltammetry (FSCV). These results extend our understanding of the N/OFQ system in brainstem circuits implicated in many neurobehavioral disorders.
Industry of Retro or Retro-industry
Authors: Apryshchenko Victor
Published: August 2020

This article deals with some puzzling features in/of contemporary Russian collective memory. In terms of methodology, the article is based on (1) the idea of the commodification of collective memory and (2) the strong interconnections between memory and national identity. While analyzing popular, historical, and political narratives such as those concerning national celebrations, historical texts, and political declarations, I argue that the Ukrainian crisis produced a new type of historical consciousness in Russia, which is connected with the conservative populist tendency in Russian politics currently. As an element of the cultural “industry,” collective memory is connected with an asymmetric exchange that appears in the process of mnemonic commodification. The surplus value of collective memory is caused by the fact that it is used in the process of popular mobilization. I conclude that to maintain the regime and to mobilize support, officials aim to rebuild Soviet images and promote an alternative to the Western model, and that they therefore seek to emphasize traditional values and retro-size Russian contemporaneity.
Return of the Local Democracy to the Territory of the Military Training Areas (Case Study the Czech Republic)

Published: August 2020

The return of the local democracy to the military training areas raises a number of complex challenges even under the conditions of a democratic state. In the municipalities that were established in the Czech Republic on 1 January 2016 by a separation from the territory of the military training areas, a nondemocratic paternalist system has dominated for many decades at the local level, which in some cases was deepened by a presence of the foreign Soviet army. While other municipalities in the post-communist period after 1989 have undergone a complex development and have gradually responded to new challenges (e.g., the use of subsidy titles, intermunicipal cooperation), and, in the case of the settlements in the territory of the military training area districts, nondemocratic local paternalism was preserved until the end of 2015. In the first phase of their term, the elected representatives of the local government primarily focused on securing the basic functions of the municipality (issues of housing and basic amenities of the village—school facilities, shops), saving local sights as remnants of historical memory, and developing cooperation within different networks of actors on a general level (e.g., issues of tourism development, environmental protection).
Small-Time Clientelism
Authors: Giugăl Aurelian , Costinescu Ion Matei
Published: August 2020

The extant literature on clientelism has tended to focus on large parties. This article asks what happens to small parties that operate in an electoral system dominated by large clientelistic parties. Our case study is the Romanian National Liberal Party (PNL). During the last two decades, it has become the second-largest party in Romania. This is unusual because the liberals in post-communist countries are politically weak. The main base of liberal support is typically urban middle classes. By contrast, PNL's electoral base is in the economically underdeveloped rural world. Using electoral statistics, economic datasets, and qualitative analysis, we demonstrate that PNL's success was due to pork-barrel spending and the development of clientelistic networks in which local mayors play a key role. PNL was able to grow by following the example of the dominant parties and creating networks of loyal mayors. In turn, this opens perspectives for research about clientelism in small communities, as well as comparative studies based on small parties.
Transnistria as an Instrument of Influence of the Russian Federation on the Security of Moldova in the Second Decade of the 21st Century—Selected Aspects
Authors: Miarka Agnieszka
Published: August 2020

The aim of the articler is to analyze and characterize the influence of the Russian Federation on the security of Moldova through cooperation with the nonrecognized Pridnestrovian Moldavian Republic (PMR). My research hypothesis is that the Russian Federation, through its multifaceted (time-varying) support to Transnistria, strengthens its pro-Russian character, thus making it an effective instrument for influencing Moldova's security. The research used methods characteristic for qualitative research, such as analysis and interpretation of documents of the Republic of Moldova and statements of leading Moldovan and Transnistrian politicians. The results of the research indicate that the Russian Federation's support of Transnistria with military and nonmilitary means in order to exert pressure on Moldova. The para-state is a convenient tool for influencing the shape of security policy created by Moldovan decision makers in order to undermine Moldova's aspirations to participate in Euro-Atlantic structures, for example, the European Union, and maintain it as part of Russia's traditional sphere of influence. The measures taken by the Russian side reduce Moldova's security, while posing a challenge to maintaining regional security in the long term.
Young People and Political Activism in Moldova
Authors: Dragoman Dragoș , Luca Sabina-Adina
Published: August 2020

The election of a Socialist and pro-Russian candidate in December 2016 as president of Moldova marks a new turn in Moldovan politics. This is in contrast with the pro-Western attitudes of the previous government. Political instability and changing international orientations, as emphasized by this article, are partly due to political alternative victories of parties supported by different social groups. Focusing on young people's activism, the article underlines the differentiation between the political success made possible by street protests in April 2009 and the political failure in December 2016. The findings may add a new explanation to Moldova's permanent instability.
The De-legitimization of General Jaruzelski's Government by Official Mass Media
Authors: Dupuis Indira
Published: August 2020

In this article, I present the results of an analysis of print media reporting on the spectacular trial in 1984 against the murderers of Jerzy Popiełuszko in communist Poland. The aim of my research is to show how the coverage contributed to the de-legitimization of the Communist Party despite the mass media system's tight structures of control. Because of mass media functionality, the coverage of this event contributed to political transformation not only by publicizing a hitherto tabooed topic but also by establishing an initial point for informed public criticism of the government.
Marx, Silk Poems, and the Pretext of Qualities
Authors: Crim Kathryn
Published: August 2020

Karl Marx’s comments on silk manufacture in “The Working Day” chapter of Capital, volume 1, demonstrate how “quality”—usually associated with “use value”—has been mobilized by capital to naturalize industrialized labor. Putting his insight into conversation with a recent multimedia poetic project, Jen Bervin’s Silk Poems (2016–17), this essay examines the homology between, on the one hand, poetry’s avowed task of fitting form to content and, on the other, the ideology of labor that fits specific bodies to certain materials and tasks.

Published: August 2020

Optimization is one of the important process in solving engineering problems. Regrettably, there are numerous problems in practical optimization that cannot be solved flawlessly within reasonable computational effort. Thus, metaheuristic approach is often useful to get near-optimal solution when the best solution is not achievable. This paper demonstrates the usefullness of a metaheuristic algorithm called single-solution simulated Kalman filter (ssSKF) in helical spring design, which is an example of structural engineering design problem. The ssSKF is a single agent-based optimization algorithm based on the Kalman filtering. The solution obtained by the ssSKF is compared againsts the genetic algorithm, co-evolutionary particle swarm optimization, co-evolutionary differential evolution, bat algorithm, and artificial bee colony.

Hence, digital storytelling is designed to occupy those needs and is expected to be useful to teach narrative.
Potential relationship between self-efficacy beliefs and proficiency in grammar among tertiary EFL learners
Authors: Kholili Achmad
Published: August 2020

A multitude of studies on self-efficacy beliefs have been undertaken to date, especially in language learning. However, little evidence is given on looking into the relationship between self-efficacy and English grammar. To this end, the present study goes about identifying to what extent the correlation between learners’ self-efficacy and their achievements in the grammar test is.  Drawing on the correlational design, an English grammar test was administered to the learners to know the learners’ acquaintance with the English grammar. Meanwhile, a self-efficacy questionnaire was performed by the researcher to the learners to figure out to what extent their efficaciousness is. A Pearson-product moment correlation was performed to analyze the relationship between such variables. The result demonstrates that there is a high positive significant correlation between learners’ self-efficacy and their attainments in the grammar test, displayed by r Correlation = +1. This finding brings a recent insight in the field of language learning.

This study focuses on English teachers’ methods in teaching reading comprehension of procedure text. The main purpose of this study is to describe the methods used by English teachers and reveal the strengths and weaknesses of those methods used for teaching reading comprehension of procedure texts. The research was a qualitative case study. The participants of this research were two English teachers at one of junior high schools in Semarang  in the academic year of 2019/2020. In collecting data, several data collection instruments were used, including: interview, observation guideline and document analysis checklist. The findings showed that English teachers planned the teaching materials and strategies in advance. They also used various methods in teaching reading of procedure text. Both teachers almost used the same methods which were audio-visual method, scaffolding, grammar-translation method, and project-based learning. The difference was in the step of the strategy implementation. In addition, the findings showed that the most appropriate method in teaching reading comprehension was grammar-translation method since it helped students comprehend the procedure text. There were several students who still had a hard time following the lessons. Teachers are supposed to make sure that all students have understood the whole text or not and they should observe the students’ situation and needs so that the teaching and learning is contextual.

When studying the regular quality practices in hospitals, it is essential to focus on the 5S as it reflects the daily activities of healthcare providers. The aim of this research is to study the effect of 5S-quality approach on employee performance in some Lebanese hospitals. Based on a quantitative approach, a survey was conducted among four hospitals in South Lebanon and 240 self-administered questionnaires were distributed randomly among target respondents. The collected primary data was analyzed by SPSS software. Statistical tests were applied for hypothesis testing such as correlation and regression analysis tests. The obtained results showed that 5S is significantly and positively affecting employee performance except for Sort. This study was limited to the constricted geographical zone and small number of hospitals was surveyed. Future studies may enlarge the research empirically and study different quality approaches.

This study investigates the factors impact on internal audit effectiveness (IAE) in Kurdistan Iraq. Data were collected from 15 directors of Colleges and 15 internal audit managers at University of Duhok. The relationship between IAE and three principle factors has been examined using multiple regression analysis. Findings reflect that management support for IAE perceived effectiveness of internal audit from both directors of colleges and internal auditor’s perspective. Management support is related to occupy experienced and trained staff, providing sufficient resources. However, this study found insignificant relationship between independence of the internal audit and internal audit effectiveness.

Etiology of severe short stature below −3 SDS in a screened Finnish population
Authors: Kärkinen Juho , Miettinen Päivi J , Raivio Taneli , Hero Matti
Published: August 2020

Objective:

To describe the etiology of severe short stature in the Helsinki University Hospital district covering a population of 1.2 million that is subject to frequent growth monitoring and screening rules during childhood.

Design:

Retrospective cohort study.

Methods:

We identified all subjects born 1990 or later with a height SD score <−3, after the age of 3 years, from the Helsinki University Hospital district growth database. A total of 785 subjects (376 females and 409 males) fulfilled our inclusion criteria; we reviewed their medical records and growth data and report their underlying diagnoses.

Results:

A pathological cause for short stature was diagnosed in 76% of the girls and 71% of the boys (P = NS). Syndromes were the most numerous pathological cause (n = 160; 20%), followed by organ disorders (n = 127; 16%), growth hormone deficiency (GHD, n = 94; 12%), SGA without catch-up growth (n = 73; 9%), and skeletal dysplasias (n = 57; 7%). Idiopathic short stature (ISS) was diagnosed in 210 (27%) subjects. The probability of growth-related pathology, particularly of a syndrome or skeletal dysplasia, increased with the shorter height SD score and the greater deviation from the target height. Sitting height to height SDS was increased in subjects with ISS, GHD, and SGA (all P < 0.01).

Conclusions:

Height <−3 SDS after 3 years of age usually results from a pathological cause and should be thoroughly investigated in specialized health care. The chance of finding a specific etiology increased with the severity of short stature, and the mismatch with target height.
HYPOXIA AND REPRODUCTIVE HEALTH: The presence and role of hypoxia in the endometrium
Authors: Martínez-Aguilar Rocío , Kershaw Lucy E , Reavey Jane J , Critchley Hilary O D , Maybin Jacqueline A
Published: August 2020

The endometrium is a multicellular tissue that is exquisitely responsive to the ovarian hormones. The local mechanisms of endometrial regulation to ensure optimal function are less well characterised. Transient physiological hypoxia has been proposed as a critical regulator of endometrial function. Herein, we review the literature on hypoxia in the non-pregnant endometrium. We discuss the pros and cons of animal models, human laboratory studies and novel in vivo imaging for the study of endometrial hypoxia. These research tools provide mounting evidence of a transient hypoxic episode in the menstrual endometrium and suggest that endometrial hypoxia may be present at the time of implantation. This local hypoxia may modify the inflammatory environment, influence vascular remodelling and modulate endometrial proliferation to optimise endometrial function. Finally, we review current knowledge of the impact of this hypoxia on endometrial pathologies, with a focus on abnormal uterine bleeding. Throughout the manuscript areas for future research are highlighted with the aim of concentrating research efforts to maximise future benefits for women and society.
Los usos del fracaso

Las historiografías andinas están impregnadas de una extendida idea de mutilación territorial, que tiende a victimizar la imagen de nación, a la vez que recrea una especie de imaginario de cercenamiento real y simbólico de su original grandeza. Esta especie de “mito de origen” oculta la ausencia de proyectos nacionales integradores e inclusivos en Ecuador, Peru y Bolivia. La noción de pérdida parece constituir un atributo, pues, lejos de debilitar el imaginario colectivo de la nación, tiende a reforzarlo y a brindarle legitimidad. En tiempos prehispánicos, las sociedades de estos tres países han estado históricamente articuladas. Se trataba de lógicas ajenas a las de la cartografía colonial, la dinámica de los Estados decimonónicos y de sus élites criollas. En la actualidad, el factor territorial no juega un rol primordial en las representaciones de legitimidad de los países centroandinos. Sin embargo, la impronta de la mutilación territorial ha marcado significativamente las identidades de sus actores sociales.
Network Communication: Algorithmic and Risky Connection
Authors: Kostenko Natalia
Published: August 2020

The article presents methods of reasoning about the modern algorithmic culture defined by the communicative modes of networks. It is emphasized that, regardless of the biases and accentuations of theoretical thought regarding the information environment and digital communications, the transformation of operator statuses and the mechanics of exchanges, the conceptual space is increasingly leaning towards variations in modeling the interaction of human and non-human agents, in parity or enhancing the privileges of everyone. In support of this, cases of mutual observability of complex algorithms of status online platforms and financial markets, that increases their micro-temporal predictability; the use of botnets of infected computers without the consent of their users in an attack on targeted websites, demonstrating the capabilities of internal machine logic; broadcasting “fake news” in informative practices inspired by human intentionality and adjusted by network generativity are considered. In attempts to discuss socio-technical media reality, discourses of power systems, hierarchical structures and civil society are combined with an understanding of the processes of “social submission” and “machine enslavement”(Deleuze, Guattari), the “technical mentality” (Simondon), as the ontogenetic ability of complex machines to autonomous and self-referential development, that should not be ignored or exaggerated. The search for “non-technical” semantics for describing the media state, updating an acceptable language for sociology, without losing the patterns and facts of media reality, providing a speedy universal connection, producing new solidarity and disunity, changing meanings, but also exuding virulence, remains urgently needed.
