Authors: Sulym Borys
Published: February 2021

The main directions of development of Ukrainian-Polish trade relations are considered in the article. The positive and negative effects of cross-border cooperation in trade and investment are substantiated, as well as a number of recommendations for building mutually beneficial relations on the basis of national interests.The purpose of this article is to assess the Ukrainian-Polish trade and economic relations in modern conditions in order to form scientifically sound recommendations for the development of mutually beneficial cross-border cooperation, taking into account national interests.Research methods. Methods of scientific analysis are used in the critical assessment of the concept of free market and free trade; comparison in the study of the dynamics of Ukrainian-Polish trade relations; graphical method for displaying and comparing trade in goods and services and investment between Poland and Ukraine; method of generalization in the development of proposals to improve the efficiency of cross-border trade and investment between countries, taking into account national characteristics and interests.Results. An assessment of Ukrainian-Polish trade and economic relations over the past ten years is given. It is proved that Ukrainian-Polish relations in the field of trade in goods do not have significant benefits for the Ukrainian economy, as their balance is negative during the period under study. Emphasis is placed on mutual exits in the field of trade in services, where the Polish side actively uses Ukrainian enterprises to order services for processing material resources through cheap labor, which stimulates the inflow of funds into Ukrainian business, job creation and more. There is a significant predominance of Polish investment in the national economy over Ukrainian investment in the Polish economy, due to the higher development of the Polish economy and interest in building branches and subsidiaries of Polish enterprises.A number of measures have been proposed to increase the economic complexity of the domestic economy in order to increase technological exports to Poland and equalize the trade balance between the countries; the directions of development of trade in services (in particular medical services in the conditions of COVID-19), as well as measures to increase the volume of Polish investment are substantiated.
Pick out the jams

Characterizing independent record shops as ‘curated’ is a recent trend in scholarship on the topic of music consumption. The processes that contribute to this description, however, are often not interrogated and ‘curated’ is taken as given, though this adjective is in actuality a representation of a rich and varied skill set that is essential to the running of a shop. This article draws on in-depth interviews with independent record shop owners and staff members to examine the processes involved in selecting and displaying stock in shops that predominantly carry used LPs and CDs, and argues that these processes are complex and underpinned by particular areas of expertise and acquired experience.
Right time, right place

To mark the 40th anniversary of punk rock, the British Library ran a free exhibition and a series of associated live spoken-word events in the summer of 2016. Punk was always both outsider (rhetoric, sound, fashion) and insider (the big names of the first-generation UK bands mostly signed to major labels). Using Simon Frith’s framework of three overlapping discourses in popular music (folk, pop and art) I argue that the contradictory strands of ideology in and around punk made the British Library the perfect site for this show.
Ewolucja zawodu i kształcenia architektów w Niemczech od II połowy XVIII wieku do 1933 roku
Authors:   Dr, Instytut Historyczny, Uniwersytet Wrocławski, Polska, Nikel Joanna
Published: February 2021

The aim of this article is to show the range of responsibilities, professional and business titles and the evolution of the system of architectural education, functioning on the territory of selected German states, which in 1871 formed the Second German Reich. Other German-speaking countries, such as Austria or Switzerland, have been omitted, as were those Polish territories under the Prussian and Austrian partition. These issues, despite numerous German-language publications (Bolenz 1991; Schnier 2009; Mai 2012) and English publications (Kostofa 1986), pose many problems for Polish researchers, especially those researching the history of architecture of former German-speaking regions, and the lack of research is not compensated for by modest Polish publications (Serdyńska 2015). The main research questions that are posed concerned issues related to the education of architects and the conditions within their profession. The 18th century was the starting point for my reflections, when the first academic centres for the education of architects in the German-speaking area were established. The thought of the 18th century as a caesura for the architectural profession is also dictated by the effects of the Industrial Revolution, which determined the emergence of professional specialisations in construction and, in the long term, determined the modern understanding of the words architect and engineer. The year 1933 marks the endpoint of the ensuing paper, when, as a result of the takeover of power by the National Socialists, a violent and radical process of building a totalitarian society began in Germany, in which higher education and the fine arts, especially architecture, were subordinated to Nazi ideology.

Published: February 2021

Mobile robots have received much of attention in the last three decades due to their very high potential of applications such as smart logistics, exploration, and intelligent services. One of important functions of mobile robots is the navigation in which robot must know their location, the maps of environment and perform path planning with obstacle avoidance. In this work, we introduce an improvement of control algorithm for mobile robot using multi-layer sensor fusion toward the target of efficient obstacle avoidance. Based on our method, we used three layers of sensors arranging in three height-different planes of robot’s housing for sensor fusion. A control algorithm, which is extended from the so-called bubble rebound algorithm and uses signal from sensor system, was proposed. Experimental implementation on a mobile robot, named EAI, shows that our algorithm can control the robot to navigate and avoid obstacles much efficiently, in which obstacles in forms of different shapes and height can also be avoided. A high repeatability and stability of the algorithm is obtained.

Published: February 2021

This work deals with systems whose dynamics are aﬃne in the control input. Such dynamics are considered to be significantly diﬀerentially expressed in a canonical form, namely the quadratic (pseudo) port-Hamiltonian representation, in order to explore further some structural properties usable for the tracking-error passivity-based control design. Diﬀerent kinds of linear and nonlinear engineering systems including an open isothermal homogeneous system and a continuous biochemical fermenter are used to illustrate the approach.

Published: February 2021

Background. One of the main reasons for the incorrect differentiation of obstructive and non-obstructive disorders of the upper urinary tract (UUT) is age-related morphofunctional immaturity of the kidney and its structures in children of the first three years of life. Aims to investigate to determine the peculiarities of urodynamic disorders of the UUT in infants with congenital hydronephrosis using diuretic pyeloehography (DРG) method. Methods. There were studied DPG data of 55 patients aged 336 months with unilateral hydronephrosis of IIII grades SFU, which were divided into groups in accordance with the variant of violation of the urodynamics of the UUT (obstructive, obstructive-hypertensive and disadaptive). The variants established according to the parameters of the DPG (transient coefficient PUJ (Kpus), the coefficients of postfurosemide adaptation (Ka) and the efficiency of emptying (Ko) pelvis). The obtained data are compared with the conclusions of morphometric studies of the operated 20 children with ureteropelvic junction obstruction (UPJO). Results. The obstructive-hypertensive variant was determined in 18 patients, obstructive in 20, and disadaptive in 17. The severity of pelvic dysfunction (according to Ka and Ko) did not correlated to the grade of UPJO (according Kpus) in most cases. Intergroup and intragroup variability in the values of the DРG coefficients is confirmed by the results of PUJ and pelvis morphometry. The correlation between hystological modification in the pelvis and DPG parameters was revealed. Obtained data allowed to introduce a new indicator urodynamic indicator of quantitative assessment of functional insufficiency of the UUT. And the score gradation of each DРG coefficient (from 0 to 4 points) in accordance with deviation from the reference values was developed. The total indicator functional insufficiency is expressed by the sum of points (SP) for each coefficient (Ka, Ko, Kpus). When SP is less than 3 points light, 46 moderate, 79 expressed and 1012 severe grade of violation of urodynamics. The severity of dysfunctions of the UUT in 88% of children (n = 15) with a disadaptive variant corresponded to light degree, in 75% of patients (n = 14) with an obstructive-hypertensive variant expressed (50%) and severe (25%) grades. Moderate degree of dysfunction revealed in 65% of patients (n = 13) with an obstructive variant. Conclusion. The severity of urodynamic dysfunction of the UUT in this age group can be determined by the score gradation of the DPG parameters which reflects the functionality of the pelvis/PUJ and the grade of their violation adaptive reactions in response to diuretic.

Published: February 2021

Toll-like receptors (TLRs) are important players in innate and adaptive immune responses involved in the initiation of the inflammatory process in response to the stimulating influence of endogenous (аllarmine) and exogenous ligands (pathogens viruses, bacteria, fungi). It has now become apparent that not only viral and bacterial infections but non-infectious inflammatory diseases are accompanied by the activation of inflammatory response systems and the development of chronic inflammation associated with disorders in the regulation of the TLRs system. In this regard, the ligand-independent activation of TLRs, which occurs with the participation of lipids, is actively studied. Their signalling functions of TLRs implemented in unique microdomains does membrane lipid rafts that coordinate many cellular processes. The ability to activate TLRs has been found for saturated fatty acids (SFAs), both exogenous and endogenous. On the other hand, TLRs can be inhibited by omega-3 polyunsaturated fatty acids (PUFAs), which can block the inflammatory process. The activation of TLRs triggers a signal cascade that induces the production of reactive oxygen and nitrogen species. The development of oxidative stress is accompanied by the formation of oxidized forms of phospholipids (Ox-PLs), which also induce the development of chronic inflammation. At the same time, Ox-PLs is characterized not only by pro-inflammatory but also anti-inflammatory activity, which necessitates in-depth studies of their role in the implementation of these processes. This review article discusses the mechanisms by which SFAs, PUFAs, and Ox-PLs modulate TLRs activation in lipid rafts. Research into the details of these mechanisms will contribute to the development of a strategy to reduce the risk of chronic diseases caused by inflammatory reactions mediated by TLRs.
Lak proverbs with the religious code of culture
Authors: Abakarova Mariana
Published: February 2021

The article analyzes Lak proverbs with the religious cultural code. The research was based on the descriptive method, syntactical analysis, morphological analysis and cognitive analysis. The proverbs collected from 3 books of Lak proverbs were analyzed from the point of view of semantics, axiological connotations, syntax and morphology. Semantic analysis revealed 6 groups of lexemes: (1) denominations of people; (2) words related to religious pillars and rituals; (3) words related to holy scriptures, religious attributes and terms; (4) words denoting death and afterlife; (5) words denoting commendable religious acts and notions; (6) words denoting sin and punishment. In the course of the axiological analysis there have been defined proverbs with positive evaluation of a person and proverbs with negative characteristics of a person. Positive traits include honesty, piety, decency, erudition and diligence, while negative ones include insulation, indecency, hypocrisy and negligence in the religious worship. Syntactical analysis of the Lak proverbs has revealed the presence of adverbs of asyndetic structure within which there have been established adversative, concessive and comparative relations, as well as of proverbs with copulative and disjunctive conjunctions. Some of the proverbs are based on the principle of alogism. Morphological analysis of the proverbs has revealed the most frequent grammatical tense, the Present Affirmative Tense, which is formed by means of adding the affix -r to the present participle. The Present Affirmative Tense in the Lak language denotes an action as an attribute of the subject which explains the fact of usage of this tense in proverbs that summarize the social experience of the native speakers. Lak proverbs with the given code have not been researched earlier that makes this study relevant.
EFL TEACHERS’ PERCEPTIONS ON USING PEDAGOGICAL MODULES IN ECUADOR: A FOCUS GROUP INTERVIEW
Authors: Alvarez Llerena Carlos Lenin , Guevara Torres Pamela Victoria
Published: February 2021

English language textbooks are widely used as one of the essential resources in education. In Ecuador, local authorities created specific course books for state schools and high schools called pedagogical modules. Hence, the terms pedagogical textbook, course book, and modules will be used interchangeably. This study aims to explore perceptions of Ecuadorian English as a Foreign Language teachers on implementing the pedagogical modules to state schools, which were provided by the Ministry of Education. Besides, participants will provide perceptions on the connection of the mentioned textbooks with the Ecuadorian National Curriculum. The study includes an exploratory qualitative design using a focus group interview with eight EFL teachers from primary and secondary schools. The focus group interview findings indicated that teachers have both positive and negative perceptions towards using these pedagogical textbooks. Teachers agree that these pedagogical modules promote English learning success in a contextualized and authentic way by connecting aspects from the curriculum and current ELT principles. Nonetheless, all of the teachers indicated that integrating the pedagogical modules to state schools was, in many ways, disorganized. Based on the results, this study suggests constructive changes to specialists in charge of creating and editing EFL pedagogical modules.
Detection of thermal stability of protein site mutation based on genetic algorithm
Authors: Li Xiujuan
Published: February 2021

In order to improve the thermal stability of protein site-specific mutation, a method based on genetic algorithm was proposed to detect the thermal stability of protein site-specific mutation using Escherichia coli phytase APPA as experimental material. Based on the principle of genetic algorithm for predicting protein structures, the author designed ten mutation sites on the acid enzyme APPA to obtain APPAM10, tested the optimal pH and temperature of the two and analyzed the effect of multiple mutation sites on the temperature stability of the phytase APPA. The relative activity of APPA was greatly affected by temperature, while the residual relative activity of APPA was higher in the mutant, and K24E was the mutant with better comprehensive properties. The optimal pH value of APPA and APPAM10 was about 4, but the optimal temperature of APPAM10 was slightly higher than that of APPA. With the increase in temperature, the residual activity and dissolution of APPAM10 were higher. The temperature was higher than that of APPA. This method can effectively detect the thermal stability of protein site mutation, and the pH stability and thermal stability of APPA protein after site mutation are better than those before mutation.
Putnam se gebrekkige modellering van sy brein-in-'n-houer-denkeksperiment
Authors: Lótter H
Published: February 2021

Hilary Putnam gebruik die "brein-in-'n-houer"-denkeksperiment om die voorwaardes van verwysing (referensie) deur middel van taal te ondersoek. Hy bou 'n moontlike wêreld vir sy brein-in-'n-houer (BIH) om te demonstreer dat sulke breine nooit self deur middel van taal sal kan aandui dat hulle breine-in-'n-houer is nie. Die rede hiervoor is dat die taal van so 'n brein nooit die vermoë om te verwys ontwikkel nie, omrede die taal van die brein-in-'n-houer nooit kontak maak met 'n buitetalige werklikheid nie. Putnam maak die teoretiese aanname dat die menslike verstand geen toegang het tot 'n buitetalige werklikheid nie, buiten die toegang wat ons sintuie verskaf. Ek redeneer dat Putnam foutiewelik die buitetalige werklikheid gelykstel aan dit waartoe ons tradisionele vyf sintuie ons toegang gee. As hierdie stelling korrek is, dan is Putnam se modellering van die menslike verstand/brein onakkuraat, aangesien hy nalaat om kerneienskappe van die funksionering van die menslike brein in te sluit in sy brein-in-'n-houer-denkeksperiment. Hierdie bevinding impliseer dat mense, korrek gemodelleer, baie sterker kwaliteite besit as wat Putnam in sy BIH-denkeksperiment ten toon stel.

Die artikel bied, deur 'n bespreking van die Byderhand-Pionierprojek as gevallestudie, 'n blik op die praktiese implementering van deelnemende en skeppende interdissiplinêre projekte in die Digitale Humaniora. Die Byderhand-Pionierprojek, wat lokatiewe literatuurinstallasies in Worcester in die Wes-Kaap behels, is uniek in dié opsig dat die multimodale literatuurinstallasies vir persone met siggestremdheid toeganklik is en dat persone met siggestremdheid 'n integrale rol in die totstandkoming van die projek gespeel het. Die artikel fokus op die kontekstualisering van die gevergde deelnemende benadering; op die projekkonseptualisering en -raamwerk; op die deelnemende dinamika wat die totstandkoming van die multisensoriese tuin, die skep van die digitale literatuur daarby betrokke, en die toeganklikmaking van sodanige inhoud moontlik gemaak het (koppelvlakontwerp); en op nabetragting oor en gevolgtrekkings aangaande die projekbenadering. Deelname aan die projek het die projekspan bewus gemaak van die behoeftes van persone met siggestremdheid en van die noodsaak van groter inklusiwiteit en toeganklikheid van kultuurprodukte - in die besonder soos dit ten opsigte van koppelvlakontwerp en digitale aanbieding van literatuur tot uitdrukking kom.
Geotechnical characterisation and back analysis of a landslide in marl deposit: A case study of Algiers Sahel (coast), Algeria
Authors: Filali M , Nechnech A , de Rosa J , Gadouri H , Meziani B
Published: February 2021

The purposeof this study isto present the results of geotechnical investigations and landslide analysis in a marl deposit at the Sahel (coast) of Algiers in northern Algeria, where many landslides take place in the Plaisancian marls, particularly following rainfall periods each year, causing severe damage to infrastructures and buildings. The physico-mechanical characteristics of the soils obtained from three different sites (El-Achour, Daly-Brahim and Ouled-Fayet) were analysed to identify the mechanism of these landslides. In the study, the laboratory test results providing grain-size distribution, Atterberg limits, water content, shear strength, and compressibility were analysed. The findings showed that, although the soils were characterised by slightly higher plasticity at Ouled-Fayet, they were generally homogeneous in the studied sites. The upper soils, generally weathered, exhibited low shear strength parameters, which are lower than the undisturbed formation beneath. The stability analysis based on limit equilibrium methods (LEM) showed the significant influence of pore water pressures on slope stability, suggesting that the weathered soils are prone to instability processes due to the effect of long rainy periods.
The interception capabilities of slotted drains as pavement surface drainage systems
Authors: Jansen van Vuuren B , van Dijk M , vdM Steyn W J
Published: February 2021

The following two slotted drain installation scenarios were reviewed in this paper: a slotted drain operating individually without a median barrier and a slotted drain operating with an adjacent barrier installed along the longitudinal length of the drain. The interception capability of the two installation scenarios was experimentally reviewed and compared while imitating various conditions typically expected on South African pavements. The applied sheet flow, slotted inlet sizes and pavement slopes (longitudinal and cross slopes) were varied throughout the experiment. Interception efficiencies of the slotted inlets were experimentally calculated as a ratio of total intercepted sheet flow to the total sheet flow applied to the pavement layouts. The sheet flow applied during the experiment was analysed to estimate the rainfall intensities and flow depths that can typically occur on the different pavements for which the interception capability of the slotted inlets was reviewed. It was estimated that rainfall intensities of more than 1 000 mm/hr and flow depths higherthan 10 mm were imitated during the experiment. More than 98% of the maximum applied sheet flow of approximately 3.0 £/s/m was intercepted by the 30 mm slotted inlets regardless of the pavement slope values and type of slotted drain layout. The conclusion reached was that both these slotted drain installation scenarios operating in practice for the conditions tested would have the capability to sufficiently remove the surface water to promote road safety during wet pavement conditions.

Türkiye’de Mali Demokrasi: 2010-2019 Dönemi İçin Bir İnceleme
Authors: ULUSOY Ahmet , ELA Mehmet
Published: February 2021

Zorunlu kamu harcamalarını karşıladıktan sonra geriye kalan vergi gelirlerinin toplam vergi gelirlerine yüzdesini ölçen mali demokrasi indeksi, zorunlu harcamalar karşısında bütçe üzerindeki kontrolü, mali alanı ve hareket kabiliyetini yansıtmaktadır. Mali demokrasi indeksindeki artış kamunun mali manevra kabiliyetini arttırırken, konjonktüre göre daha hızlı ayarlama yapabileceğini göstermektedir. Ayrıca, mali demokrasi indeksindeki artış, vatandaşların kamu harcamaları konusunda daha çok söz sahibi ve bütçenin katılığının sınırlı olduğunu vurgulamaktadır. Geçmiş politika yapıcıların mali kararları zamanla vergi gelirlerini ve kamu harcamalarının katılığını etkilemiş ve birtakım harcamalar zorunlu hale gelmiştir. Benzer şekilde Türkiye’de de vergi gelirleri geçmiş dönem politikalarından etkilenirken bazı harcamaların yapılması zorunlu (katı) hale gelmiştir. Zorunlu harcamalardaki artış ise mali alanı daraltmakta ve bütçenin esnekliğini düşürmektedir. Bununla beraber, çalışmanın sonuçlarına göre Türkiye’de mali demokrasi indeksi pozitiftir. Yani, iradi harcamalar (mali alan) son yıllarda artmaktadır.

Published: February 2021

Bu çalışmanın amacı Türkiye’de bütçe açığı, kamu iç borcu ve gelir eşitsizliği arasındaki ilişkileri tespit etmektir. Bu amaç doğrultusunda değişkenler arasındaki ilişkiler 1987-2018 dönemi temel alınarak Vektör Otoregresyon (VAR) yöntemi kullanılarak incelenmektedir. Ampirik sonuçlar, Türkiye’de hem bütçe açığından hem de bütçe açığının finansman yöntemi olarak kullanılan kamu iç borçlarından gelir eşitsizliğine doğru tek yönlü nedensellik olduğuna dair kanıt sunmaktadır. Benzer şekilde bu ilişki VAR modelinden elde edilen etki tepki fonksiyonlarında da görülmektedir. Bütçe açığı ve kamu iç borç stokundaki bir şokun gelir eşitsizliği üzerinde pozitif etkileri olduğu söylenebilir. Bunun yanı sıra teorik beklentilerle uyumlu olacak şekilde bütçe açığının da kamu iç borcu stoku üzerinde uzun dönemli pozitif etkisinin varlığına yönelik kanıtlara ulaşılmaktadır. Elde edilen bu sonuçlar ise kamu iç borç stokundaki artışın gelir eşitsizliğini arttırıcı etkiye sahip olduğunu ileri süren teorik görüşleri Türkiye için destekler niteliktedir.

ABTRACT: For decades, chemical products have shown efficiency in inhibiting pathogens associated with forest seeds, but due to the high cost and environmental impact caused by it, research to find more viable and sustainable alternatives has been Held. The objective of this work was to evaluate the efficiency of Cinnamomum zeylanicum Blume extract in the treatment of seeds of Schinopsis brasiliensis Engl. And to indicate the use of plant extracts as an alternative for the control of pathogens associated with Forest seeds. For the sanity test, 500 seeds collected in 2010 and 500 seeds collected in the year 2014 submitted to treatments with cinnamon extract were used in the following concentrations: T1: solution containing 100% sterile water (control); T2: Solution containing 25% of cinnamon extract and 75% of sterile water; T3: Solution containing 50% cinnamon extract and 50% of sterile water; T4: Solution containing 75% of cinnamon extract and 25% of sterile water; T5: Solution containing 100% of cinnamon extract. The health test lasted 10 days and after this period, the pathogen was evaluated, associated with the seeds of S. Brasiliensis, through the observations of the fungal structures through a stereoscopic and optic microscope, and the help of the literature Specialized. The means were analyzed by the Tukey test at the level of 5% probability and the percentage values for the purposes of statistical analysis were transformed into arcsen√x/100.The treatment with solution containing 100% of cinnamon extract presented as the most efficient being the most suitable for the inhibition of pathogens associated with the forest seeds. Considering the results, we recommend the advancement of researches around the use of plant extracts as a solution for the treatment of forest seeds so that it becomes a viable alternative in the forestry sector.

RESUMO: A algaroba (Prosopis juliflora) é uma espécie que possui alto valor econômico na alimentação animal, destacando-se principalmente o consumo de suas vagens. Além disso, tem se mostrado como alternativa para o controle de plantas invasoras, favorecendo a redução tanto no uso de defensivos químicos com no risco de contaminação. O objetivo da pesquisa foi investigar o potencial alelopático de diferentes concentrações do extrato proveniente de folíolos de P. juliflora sobre a germinação da espécie invasora B. pilosa. Foram utilizadas cinco concentrações, 0 (controle); 25; 50; 75 e 100%, do extrato de P. juliflora, com quatro repetições de 25 sementes cada. Avaliou-se a porcentagem; a velocidade; o índice de velocidade e o tempo médio de germinação. O extrato de algaroba não afeta negativamente o processo germinativo de sementes de picão preto, não sendo indicado, portanto, para o controle desta planta invasora.

Filosofia na escola: a surdez em foco
Authors: Modesto Brennan Cavalcanti Maciel , Modesto Vera Lúcia Maria Cavalcanti Maciel
Published: February 2021

RESUMO: Pensar o ensino de Filosofia no século XXI é uma tarefa árdua. Afinal, a Filosofia em si mesma assume características não vistas em sua gênese ou em seus períodos áureos. Em razão deste intento, faz-se necessária uma investigação de natureza dupla. Por um lado, a análise lógica e gramatical das construções conceituais sobre a Escola, o Ensino e a Surdez; por outro, uma análise genética do modus operandi do fazer filosófico na Escola. Tomando como referencial a perspectiva de Educação Popular de Simón Rodríguez, a investigação versa sobre sua institucionalização, ou seja, a necessidade de responder à uma série de demandas sociais – não raramente, representadas pela sujeição à instâncias superiores de diversas naturezas isto é, compreendida enquanto componente curricular. Breves considerações sobre o ensino de Filosofia propriamente dito e seus limites na Escola Básica, para que então se desemboque numa discussão sobre os processos de inclusão de surdos nesse processo. Haja vista que a comunidade surda, em especial, carrega consigo um eminente obstáculo para com grande parte dos ouvintes, convencionalmente chamado de “barreira linguística”. A par das discussões supracitadas e de suas interfaces, é possível sintetizar as dificuldades específicas encontradas na relação entre o componente curricular Filosofia e seu ensino para pessoas Surdas, sobretudo a questão da intradutibilidade de conceitos filosóficos, suscitando que a efetividade do ensino de Filosofia para pessoas surdas está para além do bilinguismo puro e simples.

RESUMO: Este texto aborda o trabalho como fator relevante para a evasão e o retorno dos alunos que hoje fazem parte da Educação de Jovens e Adultos (EJA). Tem como objetivo compreender a interferência do trabalho para a evasão e o retorno à escola na modalidade EJA; tendo como campo empírico uma escola da periferia na cidade de Caruaru, no ano de 2019. Nos amparamos nas contribuições dos autores (Gagno e Portela (2013); Cury (2000); Groppo (2000); Freire (1996); Ribeiro (2010); Arroyo (2006); Silva e Moura (2013); e Batalha e Silva (2018), para analisar e fundamentar toda nossa pesquisa. Onde a mesma tem o seu caráter qualitativo, realizando entrevistas semiestruturada a 14 estudantes da EJA do ensino fundamental, anos finais, com uso da análise de conteúdo para a análise das entrevistas. Os resultados da pesquisa apontaram que 10 estudantes: 5 homens e 5 mulheres deixaram e retornaram aos estudos por conta da necessidade precoce do trabalho; 4 mulheres disseram ter saído da escola por conta da gravidez precoce, mas retornavam galgando concluir os estudos e entrar no mercado de trabalho. Neste sentido, observamos que o mesmo fator – trabalho, que causa a evasão escolar também é responsável pelo retorno à escola. Esse retorno traz expectativas em torno de novas condições de trabalho, salário e melhores condições de vida e uma continuidade dos estudos visando, para as mulheres, uma profissionalização.

Perfil do uso das Plantas Alimentícias Não Convencionais em Comunidades com visão sustentável em Maceió/AL
Authors: Penzo Tauan de Almeida , Bastos Adelmo Lima
Published: February 2021

RESUMO: As partes, preparos ou Plantas Alimentícias não Convencionais, mais conhecidas como PANC surgem como alternativa de alimento e/ou complemento nutricional para a sociedade, porém, não são ou são pouco difundidas na culinária, sendo mais conhecidas como ervas daninhas ou mato. Este presente trabalho tem o objetivo de identificar o conhecimento e uso das PANC por comunidades, que visam a sustentabilidade, em Maceió, capital de Alagoas, com intuito de sistematizar as práticas relacionadas a essas plantas. A metodologia utilizada buscou apresentar os dados a partir de análises descritivas qualitativa e quantitativa. Para identificar o perfil dos entrevistados e das comunidades, uma forma descritiva qualitativa foi aplicada para sistematizar os dados socioeconômicos obtidos.  As PANC foram analisadas de acordo com sua caracterização, sendo relacionado o nome popular com sua respectiva taxonomia (família, gênero e/ou espécies). Observou-se que das 3 comunidades estudadas, todas eram compostas por conjuntos de terrenos de propriedade privada, designado para moradia, mais as áreas de conservação de espaços verdes e ambientes comuns para implantação de atividades produtivas, recreativas e religiosas com práticas mais sustentáveis. A Aldeia Verde destaca-se com maior área total: 31 ha, distribuído em uma Reserva Particular de Patrimônio Natural (RPPN) de aproximadamente 17 ha de área de vegetação nativa e 8 ha de área de produção agrícola por técnicas agroflorestais. Os produtos agroflorestais são expostos na feira orgânica do Parque Shopping Maceió, demonstrando ser a comunidade mais direcionada a produção e comercialização agrícola. Concluiu-se que em relação às PANC, há um bom nível de conhecimento e uso para alimentação e comercialização, no qual citaram diversas espécies e apresentaram diversas formas de preparo. No entanto, em geral, a dificuldade de aquisição das PANC ainda é um obstáculo para o maior hábito de consumo, assim como, a necessidade de mais estudos sobre os potenciais nutricionais existentes nas diversas espécies que se enquadram no conceito PANC. Dessa forma, tornando possível a disseminação de mais variedade de PANC presentes nas mesas dos consumidores que buscam aa melhor qualidade alimentar e nutricional.

RESUMO: A produção de cerveja artesanal vem crescendo rapidamente ao longo da última década, sendo que a sua principal motivação para o consumo é a busca de autenticidade, novas experiências sensoriais e seus atributos funcionais. A adição de frutas e especiarias na elaboração ou maturação da cerveja artesanal, confere características únicas como aroma e sabor, sendo desta forma, a utilização de frutos do umbu-cajá e canela um exemplo para a diversificação com novos produtos e sabores na indústria cervejeira. Entretanto, no armazenamento da cerveja, podem ocorrer mudanças químicas e sensoriais que influenciam a vida de prateleira. Diante do exposto, o presente trabalho teve como objetivo elaborar, avaliar sensorialmente e físico-química durante 60 dias de armazenamento a cerveja artesanal utilizando o umbu-cajá e canela na maturação. Para a obtenção da cerveja American Pale Ale foi utilizado, malte Pilsen EBC 3-4,5, levedura Fermentis US-05, lúpulo, frutos de umbu-cajá e uma solução a base de canela. Após a bebida passar pelo processo de fermentação, foi adicionado a polpa de umbu-cajá e solução de canela que durou 10 dias de maturação que logo após foi envasada. Durante 60 dias foram retiradas amostras para a realização das análises físico-químicas de extrato real, aparente e primitivo, acidez total e volátil, açúcares redutores e não redutores, grau alcoólico, densidade, cor (L*, a*, b*, c*, ângulo hue) e analise sensorial foi realizada após o armazenamento. Conforme os resultados, a cerveja elaborada apresentou variações físico-químicas e as variáveis pH e densidade foram as mais influenciadas durante o armazenamento, mas se manteve dentro dos limites estabelecidos pela legislação vigente, com exceção do extrato primitivo. Quanto ao teste de aceitação sensorial, as notas demostraram que o produto elaborado foi bem aceito e se estivesse a venda 76% afirmaram que certamente compraria e possivelmente compraria, mostrando assim ser uma alternativa no mercado cervejeiro com a introdução de um produto diferenciado com potencial de mercado, agregando valor aos frutos de umbu-cajá e canela.

Published: February 2021

ABSTRACT: The objective of the current study was to assay the germination behavior of seeds from fruits collected from three natural populations of H. speciosa, located in remnant areas of Cerrado in the municipality of Porto Nacional, Tocantins state, Brazil. The studied populations were: Canaã, São Judas Tadeu and Providência. Seven genotypes were selected from each population and twenty fruits of each genotype were collected. After ripening, the fruits were manually pulped and seeds of the same genotype pooled. After cleaning, removing adhered pulp and exterior sterilization, seeds were sown in a nursery. The experimental used a Completely Randomized Design (CRD) with three replications. Four seeds of each genotype were sown per polyethylene bag and the germination monitored until the 45th day after sowing. Variables used to assay germination behavior were: Germination (G,%); Mean Time of Germination (MTG, days); Average Speed ​​of Germination (ASG, d-1), Germination Time Variation Coefficient (VCt) and Germination Synchrony Index (Z). For germination data, nonparametric Kruskal-Wallis analysis of variance was performed, followed by Dunn's test at 5% probability. There was a difference between populations for all germination variables, with the Providência population performing the best. The variables MTG, ASG and Z were significantly higher for the Providencia population. In absolute terms, ​​the Providencia population had the highest percentage of germination (G), but did not differ significantly from the São Judas Tadeu population. The results generated are important for understanding the germination of seeds of different populations of H. speciosa. This information is relevant for the ex situ spread of the species.

RESUMO: A realização de estudos que busquem validar instrumentos que auxiliem no conhecimento da vulnerabilidade que certas espécies de plantas que estão expostas em ambientes urbanos, torna-se uma ferramenta importante para a compreensão da dinâmica do estresse sob o qual estão submetidas. É nesse sentido que se destaca a assimetria flutuante (AF), ferramenta que mede o desvio aleatório da perfeita simetria morfológica bilateral ou radial dos organismos. O objetivo deste estudo foi analisar se há assimetria flutuante nos folíolos de Schinus terebinthifolius Raddi. A pesquisa foi desenvolvida no perímetro urbano da cidade de Arapiraca (Praça José Bernardino dos Santos), por meio da coleta aleatória dos folíolos de indivíduos da espécie nativa do Brasil, Schinus terebinthifolius Raddi (conhecida como aroeira vermelha), com o auxílio de um podão. Foram selecionados, aleatoriamente, 20 folíolos de seis aroeiras e analisados, totalizando 120 folíolos. Foi utilizado o teste de Shapiro-Wilk para detectar se havia AF em folíolos de S. terebinthifolius e todas as análises estatísticas foram efetuadas no Programa R, version 3.0.2. Nos folíolos de aroeira analisados não foi constatada a existência de AF em S. terebinthifolius, já que os dados diferiram da distribuição normal (p=4,721e-21), ou seja, as análises anátomo-morfológicas dos folíolos de S. terebinthifolius não evidenciaram valores significativos para AF nos espécimes coletados na Praça. Sugere-se que essa espécie pode ser uma indicadora de acumulação de poluentes.

RESUMO: A Covid-19 considerada pela OMS como uma pandemia, atingiu recentemente diversos países, inclusive o Brasil o qual é considerado o segundo país do mundo com o maior número de casos e mortes. O estudo objetiva realizar uma caracterização epidemiológica dos casos, entre os meses de maio, junho e julho de 2020, na cidade de Santana do Ipanema, Alagoas. Realizando um estudo descritivo e de séries temporais semanais, selecionando um período de 14 semanas, considerando a disponibilidade de dados desde o início da ocorrência da transmissão do vírus no município, até os casos mais recentes disponíveis. Dito isso, no período de 01 de maio a 30 de julho, foram notificados 834 casos ativos. Indivíduos do sexo feminino foram os mais afetados, onde se mantiveram acima de 50% do número de casos em cada mês. O público correspondente à faixa etária de 20 a 39 e 40 a 59 foram os mais acometidos pela doença no município. O tipo de teste mais utilizado para a detecção do vírus foi o teste rápido, seguido do RT-PCR. Assim, pôde-se observar as características epidemiológicas, os sintomas mais recorrentes da doença, a evolução do número de casos e como se comportou a taxa de prevalência da covid-19 no município. Facilitando assim, a realização de campanhas de conscientização mais incisivas e ações por parte das autoridades mais eficazes, visando a diminuição do número de casos.
