L'autonomie de l'enfant en question
Authors: Quentel Jean-Claude
Published: June 2021

Une réflexion sur l’autonomie de l’enfant ne peut se développer que dans le cadre d’une discussion sur le statut qui est le sien. Or, si ce statut s’entend d’abord dans sa dimension sociale, et plus précisément politique au sens étymologique du terme, il ne s’y réduit pas. Il soulève également une question anthropologique qui oblige à s’interroger sur une spécificité du fonctionnement de l’enfant, laquelle lui est de nos jours trop vite déniée. Sans doute l’exercice de l’autonomie s’accorde-t-il, mais l’autonomie elle-même, dans les processus qu’elle suppose, peut-elle se conférer, voire se décréter ? Qu’en est-il en fin de compte chez l’enfant ?
Sans cesse redessiner les gestes d’émancipation
Authors: Go Nicolas
Published: June 2021

Cette courte contribution se propose d’introduire au problème tant débattu de l’autonomie des élèves, non pas à partir de l’autonomie elle-même, mais d’après ce que je souhaiterais suggérer comme des conditions possibles de son élucidation : les principes d’autorisation et de coopération. Possibles mais non nécessaires, dans la mesure où ces conditions renvoient à des pratiques éducatives scolaires particulières, qu’il m’est arrivé de qualifier de coopératives complexes. Particulières, mais pas insignifiantes. Elles pourraient même constituer une pierre de touche pour la critique des effets normalisateurs que provoquent paradoxalement maintes injonctions, aussi imprudentes qu’insistantes, à « l’autonomie des élèves ». Sans doute l’autonomie est-elle l’indice d’un processus d’émancipation à l’œuvre. Encore faut-il en déterminer les possibilités réelles et en décrire les effets empiriques. L’expérience joyeuse du travail communément partagée pourrait bien, sous réserve de certaines exigences, en constituer un signe de reconnaissance.
Autonomie versus autorité : idéal éducatif ou nouvelle forme de domination ?
Authors: Périer Pierre
Published: June 2021

La diffusion de la norme d’autonomie de l’enfant dans la famille et de l’élève à l’école a modifié les dispositifs d'apprentissage et rapports de pouvoir dans la classe. La soumission des élèves à l’autorité symbolique des savoirs et à l’autorité pédagogique du maître chargé de les transmettre recule. L’éthique contemporaine de la discussion, de la négociation, de la reconnaissance des droits et libertés de l'enfant ébranle le processus institutionnel de normalisation des rôles. Dans ce cadre, il est davantage fait appel à l’autonomie des élèves chargés de s’autocontrôler, de se mobiliser dans les apprentissages ou de se juger scolairement et moralement. Or, l’apprentissage de l’autonomie nécessite des conditions socialement définies, de sorte que l’idéal d’émancipation qu’elle symbolise pourrait dissimuler les rapports de domination qu’elle perpétue sous d’autres formes. Cette problématique sera abordée sous l’angle des professeurs débutants dans les collèges populaires, c’est-à-dire dans des contextes et à un moment de forte tension entre la norme ou valeur d’autonomie et les dispositions des élèves.
Identités professionnelles des formateurs d’enseignants d’EPS en UFR STAPS lors de l’année de préparation au CAPEPS
Authors: Alanbagi Youcef , Carlier Ghislain , Mikulovic Jacques
Published: June 2021

Depuis la création des quatorze unités d’enseignement et de recherche en éducation physique et sportive (UER EPS) en novembre 1968 suite à la loi Faure, puis des UFR STAPS en 1984, avec les débats entre savoirs théoriques et savoirs pratiques, la formation des enseignants d’éducation physique et sportive (EPS) est marquée par des tensions entre les orientations professionnelles et universitaires. Cet article aborde le regard sur les contenus de formation des futurs professeurs d’EPS au certificat d’aptitude au professorat d’EPS (CAPEPS) du point de vue des formateurs d’enseignants. Cette recherche permet de mettre en évidence une distribution des formateurs intervenant lors de l’année de préparation à ce concours. Elle s’appuie sur un corpus de quarante et un formateurs impliqués dans ces masters en sciences et techniques des activités physiques et sportives (STAPS) support de la préparation, lesquels sont interrogés à l’aide d’un questionnaire qui a fait l’objet d’une analyse factorielle des correspondances. L’étude met ainsi en relief trois pôles antagonistes de formateurs : les Scientifiques, les Didacticiens et les Sportifs. Elle permet également d’identifier les difficultés qu’ont les formateurs en STAPS à se représenter leur propre fonction au sein de l’Université. En effet, nous repérons que l’image que les formateurs se font de l’enseignant d’EPS débutant, au sortir de sa formation diplômante, n’est autre que celle qu’ils pensent avoir été. Cette recherche fait écho aux travaux de Peyronie (1998) montrant l’importance de la dimension expérientielle dans la construction identitaire, de même que ceux de Pérez-Roux (2011) quand elle s’intéresse à la construction identitaire des enseignants d’EPS.
Analyse des styles ou stratégies d’enseignants dans l’apprentissage grammatical
Authors: Clauzard Philippe
Published: June 2021

Dans le cadre d’une approche « métier », il est observé ce qui particularise le travail des enseignants lors de leçons sur l’étude de la langue en école élémentaire. Un caractère générique permet de modéliser la situation concrète de travail en classe avec la mise à jour d’organisateurs de l’activité d’enseignement. À cette généricité s’ajoute une dimension singulière qui fonde une réponse personnelle à un problème professionnel consistant en « comment faire apprendre la grammaire aux écoliers ? » Une observation fine des interactions de classe qui fondent la coactivité enseignant-élèves permet au chercheur de repérer chez les enseignants des manières personnelles d’agir, d’enrôler les élèves dans la tâche scolaire, d’étayer leurs apprentissages. Cela s’effectue en fonction d’ajustements de situation, de représentations sur la zone de proche développement des élèves, de conceptions personnelles sur l’étude de la langue. Ces stratégies révélées par le chercheur permettent d’appréhender un style d’enseignement de la grammaire.
Développement et validation d’un questionnaire évaluant les attitudes socio-affectives en maths
Authors: Genoud Philippe A. , Guillod Matthias
Published: June 2021

Cette recherche porte sur la construction et la validation d’un nouvel instrument mesurant les attitudes socio-affectives des élèves face à leurs apprentissages de mathématiques. Le questionnaire est structuré selon les trois processus sous-jacents aux attitudes (registres cognitif, affectif et comportemental) et comprend également une mesure normative. Il est constitué de huit dimensions (quarante-cinq items au total) mesurant les perceptions individuelles suivantes : utilité, sentiment de compétence, contrôlabilité, affects positifs et négatifs ressentis, régulation affective, investissement, ainsi que masculinité des maths. Les résultats soulignent les qualités psychométriques de l’outil, notamment l’homogénéité interne des dimensions, la stabilité temporelle et la structure testée par le biais d’une analyse factorielle confirmatoire. Le questionnaire peut être directement utilisé auprès d’élèves (degrés du secondaire) et permet d’obtenir une évaluation concernant leurs attitudes générales en cours de maths. Il peut ainsi s’articuler de manière pertinente avec d’autres mesures ciblées sur des tâches ou activités spécifiques.
Calculation of proton charges from the electric charges of the fermions of the quantum vacuum
Authors: Guglinski Wladimir
Published: June 2021

The electric charge of the fermions of the quantum vacuum is calculated in this paper. The value of e 0 is 5.06532 × 10−45 C. From this value of e 0, together with the fundamental constants KO ,
c,   ħ   , and α = 1/137, the electric charge of the proton is calculated, achieving the value e = 1.6026 × 10−19
C, which is very close to the experimental e = 1.60218 × 10−19 C. This successful calculation represents the first objective evidence that something very fundamental is missing in the standard interpretation of quantum electrodynamics.
Chemical Bonded Oil-PTFE-PA66 Composites as Novel Tribologically Effective Materials: Part 1
Authors: Nguyen Thanh Duong , Gedan-Smolka Michaela , Kamga Lionel Simo , Sauer Bernd , Emrich Stefan , Kopnarski Michael , Voit Brigtitte
Published: June 2021

Polytetrafluoroethylene (PTFE) is characterized by outstanding non-stick properties and very low friction coefficients under tribological load. However, PTFE is incompatible with almost all other polymers exhibits cold flow and a low wear resistivity. However, PTFE can be modified e.g. in the presence of air by using high-energy radiation to achieve carboxylic acid fluorid- (-COF), carboxyl- (-COOH) functional groups and persistent perfluoroalkyl (peroxy) radicals. The hydrophilic functional groups of radiation-modified PTFE can be used to generate a chemically covalent coupling with other monomers/polymers (e.g. polyamides) via addition reactions. Another approach to get a chemical bonding of modified PTFE is the use of radicals for the covalent attachment of olefinic groups (e.g. in oils) through radical reactions. It is already known that the dispersion of modified PTFE in synthetic oils at elevated temperatures results in very stable PTFE-oil dispersions, which have improved tribological properties and are compatible with metals.The aim of this study is the development of novel tribologically effective materials based on radiation-modified PTFE, oil and polyamide 66 (PA66). In the first synthesis step, a chemical coupling between selected oils and various types of PTFE was performed. The bonding was proved by fourier-transform infrared spectroscopy (FTIR) after removing oil excess and further extraction of insoluble residue. Additional electron spin resonance measurements (ESR) showed that the linkages mainly resulted from radical reactions. The second processing step was the chemical coupling of PA66 and oil-modified PTFE by reactive extrusion. In order to get an idea about the influence of the chemical bonding of both lubricants with the polymer matrix on the mechanical material properties compared to origin PA66, multipurpose test specimens according to ISO 3167 were prepared by injection molding. It was found, that even bigger amounts of bonded lubricants did not deteriorate the mechanical characteristics in a significant manner. Finally, initial tribological testing of the novel materials was carried out by using a block on ring tribometer test set up. The antifriction and wear behaviour, as well as the transfer film thickness, were analyzed subsequently.

Published: June 2021

In this study, effect of wood flour addition on warm/cool feeling of green composite using wood flour and poly(lactic acid) was investigated for comfortability of interior product. Additive amounts of wood flour were 10 – 40 wt.%. Measurement of initial maximum values of heat flux of green composite using wood flour was conducted under constant temperature and humidity chamber. Surface of green composite using wood flour was observed by Scanning Electron Microscope (SEM). Following conclusions were obtained. The initial maximum value of heat flux of green composite decreased with an increase of wood flour additive amount until 20 wt.%. But, initial maximum value of heat flux of green composite at more than wood flour additive amount 30 wt.% almost did not change. From SEM observation, the appearance void area on surface of green composite at wood flour additive amount 20 wt.% was larger than that of green composite at wood flour additive amount 10 wt.%. Therefore, initial maximum value of heat flux of green composite was mainly affected because of increase of void area and wood flour until wood flour additive amount 20 wt.%.

Published: June 2021

In this manuscript surface roughness, coefficient of friction (COF) and tensile properties of a post-consumer cotton fabric are evaluated. Fabric roughness, COF, effective tensile force and breaking force measured by optical profilometer, CETR tribometer and Instron tensile machine, respectively. The results proved that COF could rely on fabric pattern. Moreover, microscopically roughness influences on friction and tensile properties due to surface defects. It was found that increase in roughness of textile cotton relates to increase of number of random directional fibers. These fibers intensify friction and reduce tensile properties. The reduced values of tensile (140.49 N), breaking (123.23 N) and effective tensile force (251.43 N) of warp direction are greater than values of tensile (79.54 N), breaking (67.97 N) and effective tensile force (179.69 N) of weft direction. These effects can lower cutting performance of post-consumer textile.
A case for conservation of electrical energy in Canadian underground mines
Authors: Gangal M , Pathak J
Published: June 2021

It is estimated that 61% of electrical energy consumption in underground hardrock mining operations is accounted for by ventilation and air compressors. These costs are further escalated as a result of increasing utility rates, current trends in workplace
health and safety practices for more stringent legislation affecting ventilation, and expanding mine operations. These escalating energy costs can be reduced by controlling air delivery when and where necessary, recovering waste heat from mine ventilation and compressors, and utilizing it during
winter months. Additional savings can be achieved by using alternate mining equipment. The tendency to conserve energy costs in mines also promotes the design and development of new and efficient equipment and mining methods.
Recent developments in sensors, instruments, materials, and computer technologies now permit energy management and the automation of such systems. CANMET has been pursuing energy conservation in mines for a number of years. This paper summarizes electrical energy costs and potential savings in
Canadian underground mining operations.
A comparison of support reactions to retreat longwall front abutment for two different gateroad support techniques
Authors: Corbett G R , MacDonald B , Steed C M
Published: June 2021

The federally owned Cape Breton Development Corporation (CBDC) mines approximately 2.5-3.0 Mt of coal per annum from its Phalen Colliery. As part of an ongoing process to become more commercially viable, the Corporation has implemented changes in its support
method, namely, the transition from traditional steel set inseam supports to roof bolts as primary support in the single entry longwall retreat drivages.
During 1991 and 1992, a monitoring program was implemented by the Cape Breton Coal Research Laboratory (CBCRL) to determine the loading on support systems and ground reaction in the gateroads in front of the retreating longwall faces of the 4 East and 5 East panels at Phalen Mine. The 4 East
gateroad had been supported by steel sets alone. The 5 East gateroad had been supported by steel sets as well as roof bolting and strapping of the gateroad roof. Steel sets in both gateroads were instrumented with strain gauges and load cells to record support reaction to the retreating face
abutment pressure. Multipoint borehole extensometers and multipoint strain gauged roof bolts were installed in the gateroad roof to monitor strata displacement and bolt loading above the gateroad as the longwalls retreated.
This paper describes the details of the instrumentation and monitoring techniques utilized during this program and discusses the results, trends and differences observed in the two differently supported access roadways. Work on future data acquisition instrumentation is also briefly
described.
A softening elasto-viscoplastic model for potash mines
Authors: Wan R G , Yu Y S
Published: June 2021

The aim of the model is to phenomenologically reproduce the main features of the creep behaviour of potash by blending the notion of viscoplastic regularization with concepts of strength degradation via cohesion and friction softening. The yield surface is based
on either von Mises, Mohr-Coulomb, Drucker-Prager or 3-D Hoek-Brown criterion to characterize material strength while time dependent plastic deformations follow either a simple power law or an exponential decay. In trying to predict stresses and displacements around deep level potash mines in
general, a 2-D finite element package with pre- and post-processors (VISROCK) has been developed based on the rheological model alluded to above. The time marching scheme hinges around an implicit algorithmic framework to avoid numerical instability and secure accuracy in computations. Numerical
results are presented for a complete boundary value problem which includes the analysis of a mine in Saskatchewan.
Acquisition and Dissemination of Anti-Epidemic Medical Prescriptions During the Outbreaks in the Qing Dynasty of China
Authors: Liu Xi-Yang
Published: June 2021

During the epidemics in the Qing dynasty, many medical professionals, nonprofessionals, and social organizations collected and sorted medical prescriptions related to infectious diseases. These people also compiled, published, disseminated, and consulted related medical formularies. The above historical event can be viewed as the construction and dissemination of medical knowledge. They edited and published medical formularies on infectious diseases with lower cost and in flexible ways by taking the initiative and giving full scope to creativity. Diverse anti-epidemic medical prescriptions from these medical formularies can be used for infectious diseases in the event of the outbreaks. However, the therapeutic effects of classical prescriptions and folk recipes cannot be regarded as the same. The wide circulation of anti-epidemic medical prescriptions and medical formularies was essentially a process of epidemic prevention resource allocation. Not only did it enable many nonprofessionals to participate in epidemic prevention and control, but it also enhanced awareness, knowledge, and capacity for epidemic prevention at the individual level. At the same time, due to the uneven quality and individual differences in the physical fitness and condition of the prescriptions and formularies, they had the capacity of causing inconveniences to the readers or patients.

Published: June 2021

Cystinosis is a lysosomal storage disorder characterized by cystine crystal accumulation in different parts of body including the eyes. The purpose of this article was to describe different ophthalmological abnormalities in cystinosis using multimodal imaging. A 5-year-old girl with cystinosis was assessed clinically and with slit-lamp photography (SLP), anterior segment-OCT (AS-OCT), in vivo confocal microscopy (IVCM), fundus photography, swept-source optical coherence tomography (SS-OCT), and fundus autofluorescence. Based on all findings, she was diagnosed with ocular cystinosis. Corneal crystals were better visualized by IVCM than AS-OCT or SLP. Retinal crystal were well delineated by OCT.

Published: June 2021

A 24-year-old man presented with sudden-onset bilateral simultaneous angle closure with intraocular pressure (IOP) of 30 and 52 mm Hg in the right and left eye, respectively. Ultrasound biomicroscopy detected the presence of bilateral supraciliary fluid, whereas fundus appearance was suggestive of familial exudative vitreoretinopathy (FEVR). He was managed with cycloplegics, topical steroids, and anti-glaucoma medications (AGM) followed by cryotherapy to peripheral leaking retinal vessels of both eyes, once IOP was controlled and supraciliary fluid resolved. Any patient with bilateral simultaneous angle closure must alert one to look beyond the diagnosis of primary angle closure and search for secondary causes.

Authors: More Amruta , Sen Alok , Kohli Gaurav , Shenoy Pratik , Gupta Amod
Published: June 2021

Endogenous candida endophthalmitis (ECE) being a rare entity can often be misdiagnosed particularly in a seropositive debilitated patient. Ocular syphilis may have protean clinical manifestations and may be difficult to diagnose in absence of typical clinical manifestations. A high index of suspicion based on the clinical picture and imaging features may aid in differentiating these clinical entities. We report a case of ECE in a diabetic patient with a positive syphilis serology, the co-existence of which posed a diagnostic dilemma. We discuss the pragmatic approach and management for such a perplexing scenario.
Evaluation and comparison of the porosities in the acrylic mandibular denture bases processed by two different curing cycles, using two different brands of commercially available denture base resins – An in vitro study
Authors: Kumbham Kiran Babu , Prasad B. Veerendra , Chakravarthy A. Kalyan , Avinash R. , Amulya Kukutla Sai , Pramod Kumar Gattu Balram
Published: June 2021

Purpose:

This study evaluated and compared the amount of porosities in two different acrylic materials processed by two different curing cycles.

Materials and Methods:

A total of 200 mandibular edentulous master casts were fabricated by using a standard silicone mold. These casts were divided into two groups with 100 samples for each group and each group was divided into two subgroups with 50 samples depending on the curing cycles. On the master cast, a wax pattern was fabricated with 2 mm of thickness and processed by conventional flasking method to obtain the mandibular master specimen. This master specimen along with the master cast was flasked and mold space was created for the placement of test specimens. All these samples were subjected to curing cycles along with the test specimens followed by porosity analysis of the specimens.

Results:

ANOVA analysis inferred that there is a statistically significant difference between the mean porosity values between the groups.

Conclusion:

Analysis of mean porosity of all groups reveals that heat-polymerized specimens of Dental Products of India (DPI) processed with a long curing cycle have lesser mean percent porosity values.

Нутовича в кругу подобных коллекций того времени и его оценка в культурном сообществе новейшего времени.
Отражение личностей старообрядца М.И. Чуванова и художника Т.А. Мавриной в их коллекциях иконописи
Authors: Vazhkaya M.A.
Published: June 2021

There are two collections of icons in the Department of Private Collections — the M.I. Chuvanov collection and the T.A. Mavrina collection. Despite the fact that the time of their formation is the 20th century and the subject of the collections is icon, the collections differ significantly: the personalities of the collectors — the old believer and the artist — impacted their collections in full. Mikhail I. Chuvanov was a chairman of the Preobrazhensky congregation of Old Believers, a bibliophile and a palaeographer. The collection includes icons from the middle of the 15th century to the early 20th century. The icons correspond to the canons of the Old Russian icon painting. Tatyana A. Mavrina was a painter, a graphic artist, an illustrator. The collection includes the icons of the 15th – 17th century — the icons of “northern writing”, and the icons of Novgorod and Moscow icon painting. The research includes wonderful samples of icons, which characterize the personalities of the collectors most brightly: M.I. Chuvanov found and saved prayer images for descendants of the icons; T.A. Mavrina with her love to colour collected icons-pictures, icons-tales.

В собрании отдела личных коллекций Государственного музея изобразительных искусств им. А.С. Пушкина хранятся две коллекции иконописи: старообрядца М.И. Чуванова и художника Т.А. Мавриной. Несмотря на то, что время их формирования — XX век, а предметом собирания является икона, обе коллекции разные по характеру. Личности старообрядца и художника в полной мере проявились в их собраниях. Михаил Иванович Чуванов — председатель Преображенской старообрядческой общины, библиофил, палеограф. В коллекции представлены иконы середины XV – начала XX века. Татьяна Алексеевна Маврина — живописец, график, иллюстратор. В коллекции собраны иконы XV–XVII веков. В исследовании представлены образцы иконописи, наиболее ярко характеризующие личность собирателя: М.И. Чуванов нашел и сохранил для потомков иконы — молитвенные образы; Т.А. Маврина с ее любовью к цвету собрала иконы — картины, рассказы.
Сикст IV как заказчик Сикстинских капелл
Authors: Tarakanova E.I.
Published: June 2021

The name of Sixtus IV is associated with three Sistine Chapels: in the Vatican Palace, in the former convent of San Francesco in Savona, and in the old Basilica of San Pietro in Rome (also known as the Choir Chapel and Immaculate Chapel). The former is well studied by scientists. While remaining two chapels are much less discussed in the literature since their Quattrocentist setting has largely been lost. The article compares these three major artistic orders and for the first time shows how different their ecclesiastical and social significance were, and how distinctively the outstanding personality of Sixtus IV was manifested in each of them. In the Vatican chapel are depicted his religious, political and philanthropic activities. The funeral chapel in San Pietro was designed to provide the customer with a happy afterlife and perpetuates Sixtus IV as a real Pope-King. The Chapel of the Immaculate Conception located far from Rome became the mausoleum for the pontiff's parents and provides the most complete picture of his personal qualities. In this monument Sixtus IV is shown as an attentive son, but also practically dared to put himself on a par with the saints.

С именем Сикста IV связаны три Сикстинские капеллы: в Ватиканском дворце, бывшем монастыре Сан-Франческо в Савоне и старой базилике Сан-Пьетро в Риме (также известная как капелла хора и капелла Непорочного зачатия). Первой из них посвящено множество исследований. Две другие представлены в литературе значительно более скромно (их кватрочентистская декорация во многом была утрачена). В статье путем сопоставления этих трех крупных художественных заказов впервые показано, насколько разными были их церковное и общественное значение и как самобытно в каждом из них проявилась выдающаяся личность Сикста IV. В ватиканской капелле запечатлена его религиозно-политическая и меценатская деятельность. Погребальная капелла в Сан-Пьетро, призванная обеспечить заказчику счастливую загробную участь, увековечивает его в памяти потомков как настоящего Папу-Короля. Удаленная от Рима капелла Непорочного зачатия, ставшая мавзолеем родителей понтифика, дает наиболее полное представление о его личных качествах. В этом памятнике Сикст IV не только проявил трогательную сыновью заботу, но и практически дерзнул поставить себя в один ряд со святыми.

La Importancia de la estimulación neuromotora en el desarrollo infantil
Authors: Fajardo Estrada Ana Josefina , Esteban Gutiérrez Jennie Karina , Estrada González Elly Evangelina del Rosario
Published: June 2021

El análisis sobre el impacto que tiene el ejercicio físico y el movimiento en el funcionamiento y desarrollo cerebral infantil ha provocado el interés de varios científicos alrededor del mundo con el fin de establecer su relación. 

Se han formulado diversas teorías que explican sobre la importancia de que los infantes se mantengan en movimiento para su adecuado desarrollo cerebral, así como se han diseñado programas consistentes en estimulación neuromotora con el fin de mejorar el funcionamiento cerebral tanto de niños neurotípicos como de niños con alguna alteración en su desarrollo, aprendizaje o conducta.

Estos enfoques surgen de la premisa de la neuroplasticidad, que es responsable de la creación de circuitos neuronales mediante la adecuada estimulación. Estos nuevos circuitos se reflejan en habilidades cognitivas, ejecutivas, motoras y conductuales.  El movimiento potencializa la maduración cerebral, dando como resultado la disminución de sintomatología en niños con patologías o condiciones.

El objetivo principal de este ensayo es analizar la importancia de la estimulación neuromotora en el desarrollo infantil mediante diferentes enfoques, así como mencionar algunos resultados significativos obtenidos mediante la propia práctica profesional que consisten en la disminución de sintomatología como hiperactividad, impulsividad, ansiedad, conductas disruptivas, estereotipias y mejoría de la fluidez del lenguaje expresivo en niños con alteraciones del neurodesarrollo.
O microempreendedorismo popular e a produção do espaço urbano nas favelas da Cidade do Rio de Janeiro: entre as estratégias de sobrevivência e à afirmação de outros sentidos para a organização material da vida
Authors: Varanda Ana Paula de Moura
Published: June 2021

RESUMO

As reflexões apresentadas neste artigo objetivam compreender as características assumidas pelo microempreendedorismo popular à luz de questões relacionadas ao direito à cidade, aos elementos de desigualdade que marcam a estrutura ocupacional no país e às expressões político-identitárias e culturais de que são portadores. Destas análises, emergem contribuições necessárias à proposição de programas e ações que dialoguem com práticas de solidariedade, cooperação e reciprocidade nos espaços urbanos periféricos.

Na abordagem destes processos destacamos o papel das diferenças culturais na produção do espaço, evidenciando tensões entre ações do Estado - influenciadas por lógicas que buscam impor uma paisagem e um modo de vida hegemônico - e as criações e construções relacionadas ao vernacular, inscritas na vida cotidiana de moradores de territórios populares da cidade do Rio de Janeiro.
Antioxidant effect of Achillea biebersteinii in different extracts and extinguhishing activity on DPPH
Authors: DOĞAN Duygu , MEYDAN İsmet
Published: June 2021

Achillea biebersteinii (A. biebersteinii), one of the Achillea species, has been proven to have positive effects in terms of pharmaceuticals thanks to the components it contains. Our study was designed to investigate the quenching activity of A. biebersteinii on total phenolic component, total flavonoid component and DPPH radical. The total flavonoid component amounts of the ethanol and water extract of A. biebersteinii plant were calculated to be equivalent to quercetin, and the total phenol component amounts to gallic acid. The DPPH radical quenching activity of the ethanol and water extract of the A. biebersteinii plant was investigated by modifying the Teixeira method. The copper II ion reduction method (CUPRAC) is inspired by the Apak method. We can say that the water and alcohol extract of A. biebersteinii gave good results compared to BHA and BHT, which have good quenching activity on DPPH radical. It was observed that A. biebersteinii was rich in flavonoids and phenolics. As a result of Cuprac analysis, it was stated that the effect of the aqueous extract was significant compared to the positive controls. The A. biebersteinii plant is thought to be effective in the treatment of many diseases, especially cancer, due to its powerful antioxidant and radical quenching activity.
