Rationale: The hydrogen isotopic composition of lipids (δ 2Hlipid) is widely used in foodscience and as a proxy for past hydrological conditions. Determining the δ 2H values of large,well-preserved triacylglycerides and other uniquely microbial lipids, such as glycerol dialkylglycerol tetraether (GDGT) lipids, is thus of widespread interest but has so far not been possible due to their size which prohibits analysis by traditional gas chromatographypyrolysis isotope ratio mass spectrometry (GC-P-IRMS).Methods: We determined the δ 2H values of large, polar molecules and applied hightemperature gas chromatography (GC) methods on a modified GC-P-IRMS system. Themethods were validated using authentic standards of large, functionalised molecules(triacylglycerides, TAG), purified reference standards of GDGTs, and compared to δ 2Hvalues determined by elemental analyser pyrolysis isotope ratio mass spectrometry (EA-PIRMS); and subsequently applied to the analysis of GDGTs in a sample from a methaneseep and a Welsh peat.Results: δ 2H values of TAGs agreed within error between different between GC-P-IRMS andEA-P-IRMS, with GC-P-IRMS showing 3-5 ‰ precision for 10 ng H injected. Archaeal lipidGDGTs with up to three cyclisations could be analysed: δ 2H values were not significantlydifferent between methods with standard deviations of 5 to 6 ‰. When environmentalsamples were analysed, δ 38 2H values of isoGDGTs were 50 ‰ more negative than those ofterrestrial brGDGTs.Conclusions: Our results indicate that the high temperature GC-P-IRMS (HTGC-P-IRMS)method developed here is appropriate to determine the δ 2H values of TAGs, GDGT lipidswith up to two cyclisations, and potentially other high molecular weight compounds. Themethodology will widen the current analytical window for biomarker and alimentary lightstable isotope analyses. Moreover, our initial measurements suggest that bacterial andarchaeal GDGT δ 2H values can record environmental and ecological conditions

Melanoma melanozitoak gaiztotzearen ondorioz sorturiko larruazaleko minbizi mota bat da. Azken hamarkadan gaixotasun horrek izandako intzidentziaren igoera dela-eta, garrantzi kliniko, sozial eta ekonomiko handia sortu du. Melanomaren tratamendua desberdina da tumore motaren eta haren estadioaren arabera, bai eta gaixoaren osasun-egoeraren eta adinaren arabera ere. Melanomaren tratamendu klasikoen artean, kirurgia, kimioterapia eta erradioterapia nagusitzen dira, baita zuzendutako terapia molekularra ere. Horiek, albo-ondorio larriak ekartzeaz gain, hainbat gaixorengan ez dute eraginik. Azken urteotan, immunoterapian oinarritutako medikamentuak indar handia hartzen ari dira. Terapia biologikoa izenez ezagutzen dena ere, gorputzaren defentsa naturalak minbiziari aurre egiteko estimulatzen dituen minbiziaren tratamendu mota bat da. Gorputzak berak ekoiztutako edo laborategi batean egindako substantziak erabiltzean datza sistema immunitarioaren funtzioa hobetzeko edo zaharberritzeko.

Parkinson gaixotasuna (PG), mugimenduen nahasmenduekin erlazionatutako gaixotasun neurodegeneratibo bat da. Populazio totalaren prebalentzia % 0,1-0,3 inguruan dago eta haren etiologia ez da guztiz ezaguna oraindik. Nahiz eta klasikoki gaixotasun motor bezala definitu izan den, badaude gaixotasunaren hasierako faseetan presente egon ohi diren zenbait sintoma ez motor (SEM) gaixoen % 90ean. Horien artean daude nahaste disautonomikoak, sintoma sentsorialak eta emozionalak, eta lo-nahasmenduak. Sintoma horiek goiz agertzen direnez, garrantzitsuak dira biomarkatzale klinikoak bilakatu daitezkeelako. Forma genetikoak PGaren kasuen % 15 dira eta ideia horren inguruan 2004. urtean LRRK2 genearen lehen mutazioa aurkitu zen, orain arte gaixotasuna garatzeko arriskua areagotzen duen faktore genetiko garrantzitsuena. Mutazio horietako bat euskal jatorriko biztanleen artean ohikoa zela ohartu ziren. Testuinguru horretan, gaixotasunaren prebalentzia jakin nahian, ikerketa epidemiologiko bat egin zen Azkoitian eta Azpeitian. Prebalentziaz gain, beste zenbait aldagairen artean, biomarkatzaile horien maiztasuna ere aztertu zen. Lagin berbera hamar urte pasa ondoren aztertzea interesgarria litzateke, adina, SEMen agerpena edota ingurumen-faktoreen garrantzia ikertzeko. Medikuntzako Gradu Amaierako Lana izan den ikerketa honetan, 2009an parte hartu zuten 232 pertsonetatik, 173ren informazioa jaso ahal izan da. Emaitzek diotenez, adinarekin bat, PGaren kasuen gorakada egon da. Gainera, REM loaren jokabide-alterazioak (TCSR/REMJA) etorkizunean PGa garatzeko arriskua iragar lezakeen biomarkatzaile nagusia direla ikusi da. Emaitza hauek guztiak lanak dituen mugekin aztertu behar dira, laginaren tamaina txikia baita.
European Union Security Policy: Historical Retrospection

The EU security policy is an inseparable part of the EU Common Security and Defence Policy elaborated within the EU Common Foreign and Security Policy. Sucurity and defence issues are quite vulnerable for any state sovereignty that is why it took Member Statets rather long time to agree on principles, directions and priorities of their common security policy as well as on cooperation with the NATO. With the development of the European Community, in the sphere of security policy a number of structures were established and a number of principled documents were adopted. The article researches the evolution of the EU security policy influenced by external cgallenges and threats
Гібридна війна Росії проти України: інформаційний наступ та механізми протидії
Authors: Nofenko Andrii
Published: July 2020

У статті детально розглянуто проблему інформаційної війни Росії проти Україні. Розкрито суть інформаційної війни, її трактування в межах різних підходів. На основі використання історичного, системного та структурно-функціональних методів з’ясовано основні недоліки інформаційної сфери України; виокремлено головні механізми її захисту. Серед механізмів протидії інформаційній війні Росії проти України виокремлено дві групи – нормативно-правові та інституційні. До першої групи відносяться законодавчі акти України, серед яких провідну роль у протидії інформаційній агресії Росії відіграє Доктрина інформаційної безпеки України. Серед другої групи механізмів виділяються державні й недержавні інституції, діяльність яких спрямовано на формування та реалізацію інформаційної безпеки України, а також міжнародні структури, діяльність яких націлено на нейтралізацію інформаційного впливу з боку Росії. Серед вітчизняних інституційних механізмів протидії російському інформаційному наступу важливе місце відведено Міністерству інформаційної політики України, Раді національної безпеки та оборони України, кіберполіції й ін.Значну увагу звернуто на такі механізми протидії інформаційній війні Росії проти України, як заборона російських сайтів та соціальних мереж, а також запровадження квот на українську мову у мас-медіа. Зазначено, що дії України щодо нейтралізації інформаційних загроз з боку Росії потрібно здійснювати на різних рівнях – геополітичному, ресурсному, громадськості.У ході проведеного дослідження сформовано рекомендації щодо протистояння інформаційній війні. Проведено аналіз факторів інформаційних впливів і протидії інформаційній зброї, у результаті чого вказано низку можливих дій для реалізації протидії російській інформаційній ескалації в Україні з метою створення гідної й адекватної відповіді на інформаційні виклики сучасності.Зараз уже зрозуміло, що інформаційна боротьба стає тим фактором, що впливає на саму війну, її початок, хід і результат. Це підтверджується агресією Росії проти України. Тому досить актуальною проблемою безпеки України є розробка концепції захисту системи інформаційно-аналітичного забезпечення завдань інформаційної боротьби.
ASSESSMENT OF HONEY PRODUCTION SYSTEM, CONSTRAINTS AND OPPORTUNITIES IN SELECTED KEBELES OF HAWASSA CITY ADMINISTRATION, ETHIOPIA
Authors: Negash Dinku , Mengeste Bereket
Published: July 2020

The study was intended to assess honey production system, constraints and opportunities in selected kebeles of Hawassa city administration, sidama zone in 2018/19. Production limitation has resulted with a significant complain among the beekeepers and all concerned bodies regarding the possible threat for decreasing honey production in the area. Cross-sectional types of studies were used to collect data. 20 beekeepers were selected from each kebeles using purposive sampling method to conduct formal survey with semi-structured questionnaire making a total of 100 interviewed bee keepers. The main purpose of keeping honey bees were for both income generation and home consumption. The main sources of the foundation colony were catching swarm (80%) and gift from parents (20%). Most (40%) of the beekeepers in the study area have owned only traditional hives and all the three types of hive owned (32%). Beekeepers in the study area prevent the incidence of swarming by return back to the colony (56%), removal of queen cell (16%) and cutting of combs (28%). The average amount of honey harvested per hive per year from traditional hive, transitional and frame hive was 5.6±1.49kg, 11.9±3.15kg and 10.8±2.91kg, respectively. There was (p<0.05) no variations in the five representing kebeles in honey yield/hive/year in traditional, transitional and frame hives. Beekeepers of the study area sold the honey at the nearby market (92%) and major marketing place (8%). According to the respondents, they mostly sold the honey to consumer (64%) and tej house (28%). The most important constraints of beekeeping in the study kebels were lack of Absconding (1st), Lack of training (2nd), Pests and predators (3rd), Lack of extension services (4th), Agro-chemicals (5th), Lack of cooperative (6th), Swarming (7 th) and Lack of beekeeping equipment (8th) Lack of bee colonies (9th), Lack of good market (10th), Drought (11th) and Shortages of bee forages (12th). In order to address the skill gap on honey production system and post-harvest handling of hive products practical training on bee and bee products management should be given.
HOMER’S CONCEPTION OF HONOUR AND GLORY IN THE ILIAD
Authors: Ishtiaq Muhammad
Published: July 2020

The Iliad is an ancient Greek epic poem which portrays the duration of Trojan War along with battle and events between King Agamemnon and the warrior Achilles. In this paper, the honour and glory of ancient Greek civilization has been discussed in context of The Iliad. The definitions of honour and glory has been discussed along with what motivated the ancient warriors to fight for honour and glory. This study has been carried out to find out the importance standards of honour and glory along with the importance of honour and glory in lives of Greek warriors. One of the central ideas of the Iliad is the honour that soldiers earn in combat. For an ancient Greek man, the ability to perform in battle is the single greatest source of worthiness. The glory earned by soldiers on the battlefield enabled them to live on in legend, becoming heroes who would be remembered long after death. This essence of honour and glory has been discussed in this paper. This paper has also emphasized on the heroic honour of the Greek warriors as performance of war was the simplest measurement tool to measure the heroic honour of the warriors.
Relación entre Tmax y Reflectancia de la Vitrinita en las cuencas de ante-arco del Sur-Oeste del Ecuador

Published: July 2020

La cuantificación de Ro y Tmax son dos técnicas independientes utilizadas para caracterizar la madurez termal de las rocas. Más aún, varios estudios han demostrado que existe una relación lineal-directa entre estos dos parámetros. Para el caso de las cuencas del Sur-Oeste de Ecuador, se ha establecido una ecuación [Ro = 0.0228*Tmax – 9.21] basada en las muestras de los pozos Tiburon-0001 y B2-ANX1-1X, los cuales son considerados como los más confiables. Adicionalmente, se incorporó una zona de confianza (Tmax ± 1σ). Las muestras que caen fuera de esta zona no fueron consideradas en posteriores interpretaciones. La ecuación propuesta ha sido probada eficientemente para otros pares de datos analizados en este trabajo e incluso resulta funcional para otras cuencas. La caracterización termal del Sur-Oeste del Ecuador, da cuenta de la existencia de dos zonas que habrían alcanzado la suficiente madurez termal para generar hidrocarburos. La primera está asociada con las rocas del Cretácico tardío presentes en la Cordillera de Chongón-Colonche y a rocas del Paleoceno del Levantamiento de Santa Elena. La segunda está relacionada con rocas del Neógeno y que se encuentran afectadas por el sistema de fallas Puná-Santa Clara. La madurez termal observada en estas zonas ha sido vinculada con procesos tectónicos, ya sea por la acreción de terrenos (Sistema Cretácico tardío – Paleoceno) y al escape del Bloque Nor-Andino (Sistema Neógeno).
A Escola de Educação Física e Desposto da UFRJ (1979-1985)
Authors: Gonçalves Baptista Guilherme , Da Motta Silva Gustavo
Published: July 2020

Embora haja produções sobre a formação do professor de Educação Física ao longo da Ditadura civil-militar brasileira, poucos estudos investigaram a recepção dos discursos e das práticas pelos alunos nesse momento. Pautado nos referenciais teóricos de Bourdieu e Elias, esse trabalho investigou a relação entre os discursos presentes na formação de professores na Escola de Educação Física e Desportos (1979-1985) e os dispositivos usados pelos alunos para obter sucesso em seus caminhos. Utilizou-se a análise documental (Atas de Congregação e do Conselho Departamental da instituição) e fontes orais (três entrevistas com professores do período). De modo geral, os alunos compreendiam suas posições e as relações de poder na instituição, apoiando suas ações nessas condições. Evidenciou-se, assim, o protagonismo dos indivíduos que não aceitavam passivamente o(s) modelo(s) de formação, mas interferiam nele(s) por meio de escolhas, estratégias, rejeições e/ou convergências.

Authors: Assen de Carvalho Mark Clark , Marques Gonçalves Rafael , Xavier Silva Adão Rogério
Published: July 2020

Este artigo apresenta parte de uma pesquisa historiográfica que objetiva descrever o advento do ensino superior no Estado do Acre. Para tanto, situa o contexto de criação das antigas Faculdades isoladas, perpassando pela Faculdade de Educação do Acre no cenário de constituição do Centro Universitário do Acre, a implantação de uma Universidade Estadual, o processo de federalização da Universidade Federal do Acre – UFAC e as mudanças decorrentes deste movimento. Trata-se de pesquisa documental entrelaçada a relatos e depoimentos de diferentes atrizes históricas que exerceram protagonismo nos primórdios da Educação Superior no Acre. No geral, são descritas as diferentes circunstâncias econômicas, políticas, sociais e educacionais que movimentaram as iniciativas em torno do processo de criação do ensino superior na década de 60 e suas transformações nas décadas subsequentes do Século XX. Importa destacar que nesse processo de imersão e regressão na história da Educação Superior acreana tem-se como questão central o movimento em prol da implantação da Faculdade de Educação e o papel desta unidade no processo de formação de professores, descrevendo, em igual medida, sua transformação em Departamento de Educação e em tempos mais recentes sua fusão enquanto Centro de Educação junto às áreas de Letras e Artes, aspecto que contribui para que tenha havido um movimento de enfraquecimento da ação política e da dimensão pedagógica e formativa outrora desempenhada pela extinta Faculdade de Educação.

Musculoskeletal complaints are generally felt a lot because of the habits done during work. Body posture when working improperly and maintained in a relatively long time can lead to musculoskeletal complaints. Working in a sitting position for a relatively long period of time with a bent and bent body position can be a risk factor for complaints of neck pain or back pain. This study aims to analyze the relationship between long-standing work posture with subjective complaints of neck pain in leather craft industry workers in Selosari. The study design was an observational analytic study with a cross sectional approach. The sampling technique in this study was proportional random sampling with a sample of 42 respondents from the leather craft industry workers in Selosari. The results of statistical analysis with the Chi Square test showed that p=0.006 (p <0.05), which means there is a relationship between the length of maintaining work posture to subjective complaints of neck pain in leather craft industry workers in Selosari. It should be noted that prolonged retention of neck posture which is too bent when working continuously for long periods of time will increase the risk of neck pain complaints. So it is necessary to improve the posture of the body when working, especially the neck or movement or changes in posture, especially the neck if it starts feeling stiff or stiff in the neck.

Published: July 2020

Background: The level of post-traumatic stress symptoms (PTSS) associated with the COVID-19 outbreak, stress, anxiety and depressive symptoms was assessed. Risk factors for mental health in the Polish population have been identified.Methods: The 926 respondents completed a set of questionnaires consisting of questions concerningCOVID-19, PTSS related to the COVID-19 outbreak (Impact of Event Scale-Revised, IES-R) and their mental health status (Depression, Anxiety and Stress Scale, DASS-21).Results: Most respondents reported severe PTSS related to the COVID-19 outbreak (44.06%), normal intensity of depressive symptoms (52.38%), anxiety symptoms (56.05%) and stress (56.48%). Female gender, parental status, having a relationship, at least a two-person household are associated with higher PTSS and DASS-21 subscale. A few physical symptoms, a medical visit, quarantine, negativehealth evaluation, and chronic diseases, knowledge of the increase in the number of infected people andthe number of deaths are associated with higher levels of PTSS. Some of the precautions and the need for additional information on COVID-10, the certainty of a high probability of contracting COVID-19, a low survival rate and concerns about loved ones are associated with higher PTSS.Conclusions: The indicated risk factors can be used to develop psychological interventions to improve mental health.
Deficits of visual working memory representations of emotional facial expressions in patients with congenital facial palsy

Published: July 2020

Recent models of sensorimotor simulation postulate that simulation aids ‘refining’ visual representations of others’ emotional facial expressions through an iterative communication with the visual system. In order to test this aspect of sensorimotor simulation models, in the present investigation we recruited a sample of patients with Moebius syndrome (MS), characterized by congenital facial paralysis, and a control group of healthy participants. MS patients constitute a particularly interesting test as their congenital impossibility of producing facial movements and expressing emotions through the face should translate into a deficit of facial expressions processing. Here, MS and healthy participants underwent a task aimed at measuring the precision with which representations of facial expressions of emotions are maintained in visual working memory (VWM) by implementing a delayed estimation task. In each trial, participants saw a face with a certain intensity of facial expression (i.e., of happiness, disgust or anger) and, after a short time interval of about 1 sec, they had to select the to-be-memorized image inside a circular array in which facial expressions of increasing intensity were presented in an orderly manner. The results indicated that MS participants built lower quality representations of the intensity of emotional expressions when compared to healthy participants. These findings support the role of sensorimotor simulation in improving the quality of emotional representations of facial expressions during early stages of processing.
Gesture Production and Theory of Mind: Effective Disambiguation in Communication through Gesture
Authors: Kim Minju , Schachner Adena
Published: July 2020

People design their speech acts with their listeners in mind, accounting for their knowledge and other mental states. Is this ability specific to spoken language and co-speech gesture, or does it appear in pantomimic gestures as well? We ask whether adults flexibly shift their silent gestures to emphasize relevant information, representing different features of the target in different contexts. In a two-item reference game, adults gestured to a partner to indicate which object was the target. Item pairs differed in one of three features (size, shape, pattern). We found that adults were more likely to gesture a feature when it was relevant to distinguishing the two possible referents, versus when it was not. Thus, adults flexibly modified their gestures to meet their partners’ needs, emphasizing the relevant feature. These data lay a foundation for future work on the development of use of theory of mind in gestural communication in childhood.

Design and experiment of ocean current power generation system have been carried out using the Bach In Indonesia, the tsunami early warning system only applies the earthquake and hydrosphere relationship model to predict tsunamis. To date, no tsunami detector has used radar or GNSS technology. GNSS technology can be applied as an early warning system for tsunamis, provided that tsunamis are caused by earthquakes greater than 7 magnitudes, occur 70 kilometers below sea level, and are caused by normal faults. This could be an alternative to Bouy GNSS which is expensive to install and maintain, especially for countries with vast oceans such as Indonesia. In this paper, a review of the application of GNSS signal reflection was carried out using one International GNSS Service (IGS) station, JOG2, and one Continuously Operating Reference Station (CORS), CLSA, each located in Java and Sumatra to investigate the availability of sea level monitoring in Indonesia. Determination of sea level is obtained from two methods, the GNSS signal phase data analysis method and the GNSS Signal-to-Noise Ratio (SNR) data analysis method. Both methods use reflected GNSS signals or multipath effects to obtain sea level. The results of the study show that the number of satellites that pass through Indonesia every 15 minutes is enough to get sea-level data  every 15 minutes to one hour. This shows that it is possible to apply the multipath effect to obtain sea level information in Indonesia to detect tides and tsunamis as part of the tsunami early warning system in Indonesia.
