EDUCAÇÃO À DISTÂNCIA E TECNOLOGIAS DE INFORMAÇÃO E COMUNICAÇÃO: FERRAMENTA COMPLETAR NA ODONTOLOGIA
Authors: dos Santos Lairds Rodrigues
Published: April 2021

Introdução: As universidades têm utilizado a Educação à Distância (EAD) e seus recursos tecnológicos como meio de auxílio no processo de transformação do conhecimento no ensino superior. Por meio dessa nova modalidade de ensino, o aluno torna-se capaz de seguir seu próprio ritmo de aprendizagem, mesmo em localidades distantes geograficamente, utilizando-se das Tecnologias de Informação e Comunicação (TIC) para ultrapassar a simples exposição oral do conteúdo. Objetivo: Dessa forma o objetivo desta revisão foi abordar sobre o uso das TIC na educação à distância no ensino superior para os cursos de odontologia como uma ferramenta complementar. Material e métodos: O período de buscas das publicações foi de setembro a dezembro de 2020. Para este trabalho foram utilizadas publicações disponíveis em meio eletrônico ou impresso utilizando artigos científicos das bases de dados, como Scielo, Pubmed e Google Acadêmico. Para os critérios de inclusão foram selecionados artigos de pesquisa e revisões sobre educação mediada por tecnologia na odontologia nas línguas portuguesa e inglesa. Foram excluídas cartas ao editor, artigos que não estavam na íntegra e aqueles em duplicata. Resultados: A subutilização das tecnologias de informação e comunicação como ferramenta complementar no ensino da odontologia pode gerar riscos aos alunos. Uma disciplina aplicada exclusivamente à distância, e sem interação do tipo professoraluno pode comprometer o aprendizado. Conclusão: A educação mediada por tecnologia é recomendável desde que se promova associação de diversas estratégias de ensinoaprendizagem. A capacitação do corpo docente para utilizá-la corretamente e com segurança, o acréscimo nas grades curriculares dos cursos de pós-graduação de disciplinas que abordem novas tecnologias para o ensino, promovem uma odontologia de qualidade e confiável.

As Tecnologias da Informação e Comunicação (TIC’s), vem ao longo dos tempos, conquistando mais espaço no processo educacional. Isso porque ela possibilita práticas pedagógicas integradas, permitindo assim, a inserção de conteúdos escolares, de diferentes abordagens. Estabelecendo possibilidades entre o aprender e o interagir. Nesta perspectiva, esse trabalho objetivou analisar e discutir sobre como as Tecnologias da Informação e Comunicação – TIC’s, vem sendo aplicadas no processo de ensino e aprendizagem em tempos de pandemia. Realizou-se uma revisão de literatura com o intuito de compreender as diferentes concepções dos autores a respeito das TIC’s, na educação. O percurso metodológico partiu de um levantamento bibliográfico, tabulação e análise dos dados. Os resultados encontrados foram que as tecnologias contribuem efetivamente no processo de ensino e aprendizagem e, em especial nesse tempo de pandemia. Com base nos resultados encontrados, notou-se que as tecnologias educacionais, são ferramentas positivas auxiliando o processo de ensino e aprendizagem. Com relação aos resultados da pesquisa o seu uso evidenciou pontos de dificuldades, mas pode-se notar que os pontos positivos e as contribuições que esses recursos e ferramentas permitem uma nova modalidade para que os alunos participem das aulas ativamente e construa o conhecimento. Analisou-se ainda, que as TIC’s, para os autores pesquisados, reforçam a sua utilização como ferramentas de apoio, pois quando utilizadas de maneira adequadas geram aprendizagens significativas e aumentam a criatividade e a motivação por parte dos estudantes, e ainda contribui para que a aula seja mais prazerosa e atrativa. Desta forma, conclui-se que as TIC’s, são instrumentos que proporcionam mais qualidade a educação.

Published: April 2021

Introdução: Com a adoção do distanciamento social devido à pandemia do COVID-19, algumas instituições de ensino vivenciam novas experiências educacionais, uma vez que houve necessidade de adequação das atividades, antes presenciais, para a realidade virtual. Uma das estratégias utilizadas para prosseguir com as atividades letivas e diminuir a sensação de estagnação diante do cenário atual foi o Ensino Remoto Emergencial (ERE). Descrição do caso: Diante do decreto governamental que paralisou as aulas presenciais, a universidade pública investigada, adotou, em setembro de 2020, o ERE para ministrar conteúdos necessários para o andamento do curso. As principais ferramentas utilizadas na metodologia de ensino foram Google Classroom e Google Meet. Docentes e discentes foram capacitados para utilização das plataformas virtuais. Dessa forma, foram realizadas atividades assíncronas, como postagem de aulas gravadas e roteiros para estudo através do Google Classroom, e síncronas, como conferências no Meet. As avaliações ocorreram de forma online, através de provas, exercícios e formulários. Material e métodos: Trata-se de um estudo descritivo e reflexivo do tipo relato de experiência, vivenciado por alunos do curso de medicina, durante o ERE em uma universidade pública do Estado do Pará, no período de setembro a dezembro de 2020. Foram coletados os relatos dos participantes. Discussão: A utilização dos recursos tecnológicos no ERE exigiu dos professores e dos alunos uma postura inovadora, alinhada às metodologias ativas de ensino, frente à prática pedagógica. Contudo, a utilização desses recursos nem sempre foi eficaz, pois a má qualidade da conexão com a internet e a falta de equipamentos para alguns alunos, tornou-se um problema para assistirem as aulas. Conclusão: Apesar das dificuldades, o ERE tornou viável o ensino dos conteúdos teóricos do curso de medicina durante a pandemia. Estratégias utilizadas durante o período possivelmente serão ampliadas para o ensino presencial.

Objetivo: contribuir com o processo de aprendizagem através de técnicas de psicoeducação. Material e Método: foi utilizada Busca Ativa Escolar como uma solução tecnológica e metodologia inovadora por meio da qual o UNICEF e outras entidades, apoiam os municípios na identificação das crianças e dos adolescentes que estão fora da escola, ajudando-os a voltar às salas de aula, permanecer e aprender. Resultados: a pesquisa foi desenvolvida por 10 estagiários do 10º período que, através de busca ativa, contataram, via telefone, 25 escolas distribuídas entre as redes municipal, estadual e privada, conseguido retorno de 18 delas, através de gestores e coordenadores, tendo sido verificado que as mesmas estão funcionando na modalidade de atendimento por formação de grupos através do WhatsApp, do Google classroom e Google meet. A estimativa foi de que 40% dos alunos, remotamente, estavam assistindo as aulas e respondendo as tarefas propostas pelos professores. Conclusão: em tempo de pandemia a proposta principal do ensino remoto não é o rendimento quantitativo, mas sim a manutenção da interação social com os alunos e desenvolver um trabalho preventivo no combate à evasão escolar, sabendo os profissionais entrevistados que vivem uma situação atípica e muito difícil, em que os professores e demais funcionários da escola estão se reinventando para chegar mais próximo aos alunos.
O ENSINO E SUA RELEVÂNCIA NO FORTALECIMENTO DA INDENTIDADE REGIONAL, VISANDO A VALORIZAÇÃO E GESTÃO DOS PATRIMÔNIOS
Authors: Pereira Natanael Alex Alves
Published: April 2021

Introdução: Quando se trata da identidade de uma região, geralmente se discutem aspectos históricos e culturais como os únicos, quando não mais relevantes, associados a essa questão. No entanto, todo e qualquer patrimônio regional possui equivalência quando se trata do sentimento de pertencimento e identidade. Partindo dessa primícia o ensino classifica-se aqui como prática essencialmente fundamental para a consolidação do conceito de identidade regional, que por sua vez se expressa no sentimento de pertencimento presente na comunidade nativa de uma região. Ao descrever o seu lugar de origem o indivíduo atribui aspectos marcantes do mesmo, se apropriando dessas características e revelando o que se entende de identitário do “seu lugar”. Neste contexto, a abordagem dos patrimônios regionais em sala de aula proporcionaria o desenvolvimento deste pertencimento de forma duradoura, considerando para tanto, a efetivação do processo de ensino-aprendizagem. Uma vez que esse processo efetiva-se, o aluno retem o conhecimento didático e associa o mesmo às suas próprias experiências no espaço em que ele está inserido. Objetivo: O presente trabalho pretende fazer uma abordagem direta a importância do ensino, relevante aqui como uma ferramenta necessária e potenciadora para o fortalecimento da identidade regional e do sentimento de pertencimento, ambos essenciais para gestão dos patrimônios regionais. Material e métodos: O trabalho se apresenta como uma pesquisa de cunho bibliográfico e qualitativo, a partir do qual foram coletados dados, bibliográficos e empíricos de contribuição essencial para a temática aqui proposta. Resultados: Resultou-se que a efetivação de projetos educacionais voltados a essa discussão induziriam e desenvolveriam uma conscientização direcionada ao reconhecimento identitário e valorização patrimonial. Conclusão: Conclui-se portanto, que a importância do ensino neste contexto é evidente, pois classifica-se não apenas no desenvolvimento da identidade regional em si, mas também, em segunda instância, na própria gestão dos patrimônios regionais, uma vez que a população teria participação direta nesta gestão.
Aprendizaje basado en proyectos: método para el diseño de actividades

La Declaración de Bolonia supuso el punto de partida para la construcción del Espacio Europeo de Educación Superior (EEES). Entre las directrices que emanan de la Declaración de Bolonia (y sucesivas) figuran, entre otras: el aprendizaje por competencias, la enseñanza centrada en el estudiante y el aprendizaje activo. Entre las metodologías de aprendizaje activo tiene un lugar singular el aprendizaje basado en proyectos (ABPt). En España, esta metodología ha tenido un éxito relativo. En las últimas décadas se han llevado a cabo un número importante de iniciativas, pero, en la mayoría de los casos, se limitan a implementaciones en asignaturas individuales, sin alcance en el currículo de las titulaciones. Y es que esta metodología no está exenta de dificultades.
Este trabajo describe un método para diseñar actividades docentes organizadas mediante ABPt. El método estará dirigido a profesores que se inician en esta metodología, de forma que les guíe en la utilización de los principios fundamentales relacionados con el ABPt. Para fortalecer esta ayuda se ha diseñado e implementado una herramienta TIC (tecnologías de la información y la comunicación) para que los profesores diseñen un plan docente siguiendo la metodología citada.
Using TROPOspheric Monitoring Instrument (TROPOMI) measurements and Weather Research and Forecasting (WRF) CO modelling to understand the contribution of meteorology and emissions to an extreme air pollution event in India

Published: April 2021

Abstract. Several ambient air quality records corroborate the severe and persistent
degradation of air quality over northern India during the winter months, with evidence of a continued, increasing trend of pollution across the
Indo-Gangetic Plain (IGP) over the past decade. A combination of atmospheric dynamics and uncertain emissions, including the post-monsoon agricultural stubble burning, make it challenging to resolve the role of each individual factor. Here we demonstrate the potential use of an atmospheric transport model, the Weather Research and Forecasting model coupled with chemistry
(WRF–Chem) to identify and quantify the role of transport mechanisms and
emissions on the occurrence of the pollution events. The investigation is
based on the use of carbon monoxide (CO) observations from the TROPOspheric
Monitoring Instrument (TROPOMI) on board the Sentinel-5 Precursor satellite and the surface measurement network, as well as the WRF–Chem simulations, to investigate the factors contributing to CO enhancement over India during
November 2018. We show that the simulated column-averaged dry air mole
fraction (XCO) is largely consistent with TROPOMI observations, with a
spatial correlation coefficient of 0.87. The surface-level CO concentrations show larger sensitivities to boundary layer dynamics, wind speed, and diverging source regions, leading to a complex concentration pattern and reducing the observation-model agreement with a correlation coefficient ranging from 0.41 to 0.60 for measurement locations across the IGP. We find that daily satellite observations can provide a first-order inference of the CO transport pathways during the enhanced burning period, and this transport pattern is reproduced well in the model. By using the observations and employing the model at a comparable resolution, we confirm the significant role of atmospheric dynamics and residential, industrial, and commercial emissions in the production of the exorbitant level of air
pollutants in northern India. We find that biomass burning plays only a minimal role in both column and surface enhancements of CO, except for the state of Punjab during the high pollution episodes. While the model reproduces observations reasonably well, a better understanding of the factors controlling the model uncertainties is essential for relating the observed concentrations to the underlying emissions. Overall, our study emphasizes the importance of undertaking rigorous policy measures, mainly focusing on reducing residential, commercial, and industrial emissions in addition to actions already underway in the agricultural sectors.

Abstract. Ectoenzymatic activity, prokaryotic heterotrophic
abundances and production were determined in the Mediterranean Sea. Sampling
was carried out in the sub-surface, the deep chlorophyll maximum layer
(DCM), the core of the Levantine intermediate waters and in the deeper part
of the mesopelagic layers. Michaelis–Menten kinetics were assessed using a
large range of concentrations of fluorogenic substrates (0.025 to 50 µM). As a consequence, Km (Michaelis–Menten half-saturation constant) and Vm (maximum hydrolysis velocity) parameters were determined for both low- and
high-affinity enzymes for alkaline phosphatase, aminopeptidase (LAP) and
β-glucosidase (βGLU). Based on the constant derived from the
high-LAP-affinity enzyme (0.025–1 µM substrate concentration range),
in situ hydrolysis of N proteins contributed 48 % ± 30 % to the
heterotrophic bacterial nitrogen demand within the epipelagic layers and
180 % ± 154 % in the Levantine intermediate waters and the upper
part of the mesopelagic layers. The LAP hydrolysis rate was higher than
bacterial N demand only within the deeper layer and only when considering
the high-affinity enzyme. Based on a 10 % bacterial growth efficiency, the
cumulative hydrolysis rates of C proteins and C polysaccharides contributed
on average 2.5 % ± 1.3  % to the heterotrophic bacterial carbon
demand in the epipelagic layers sampled (sub-surface and DCM). This study
clearly reveals potential biases in current and past interpretations of the
kinetic parameters for the three enzymes tested based on the fluorogenic-substrate concentration used. In particular, the LAP / βGLU enzymatic
ratios and some of the depth-related trends differed between the use of
high and low concentrations of fluorogenic substrates.
The late Holocene record of Lake Mareotis, Nile Delta, Egypt

Published: April 2021

Abstract. Lake Maryut (northwestern Nile Delta, Egypt) was a key feature of Alexandria's hinterland and economy during Greco-Roman times. Its shores accommodated major economic centers, and the lake acted as a gateway between the Nile valley and the Mediterranean. It is suggested that lake-level changes, connections with the Nile and the sea, and possible high-energy events considerably shaped the human occupation history of the Maryut. To reconstruct Lake Maryut hydrology in historical times, we used faunal remains, geochemistry (Sr isotopic signature of ostracods) and geoarcheological indicators of relative lake-level changes. The data show both a rise in Nile inputs to the basin during the first millennia BCE and CE and a lake-level rise of ca. 1.5 m during the Roman period. A high-energy deposit, inferred from reworked radiocarbon dates, may explain an enigmatic sedimentary hiatus previously attested to in Maryut's chronostratigraphy.
Reconstructing the dynamics of the highly similar May 2016 and June 2019 Iliamna Volcano (Alaska) ice–rock avalanches from seismoacoustic data
Authors: Toney Liam , Fee David , Allstadt Kate E. , Haney Matthew M. , Matoza Robin S.
Published: April 2021

Abstract. Surficial mass wasting events are a hazard worldwide. Seismic and acoustic signals from these often remote processes, combined with other geophysical observations, can provide key information for monitoring and rapid response efforts and enhance our understanding of event dynamics. Here, we present seismoacoustic data and analyses for two very large ice–rock avalanches occurring on Iliamna Volcano, Alaska (USA), on 22 May 2016 and 21 June 2019. Iliamna is a glacier-mantled stratovolcano located in the Cook Inlet, ∼200 km from Anchorage, Alaska. The volcano experiences massive, quasi-annual slope failures due to glacial instabilities and hydrothermal alteration of volcanic rocks near its summit. The May 2016 and June 2019 avalanches were particularly large and generated energetic seismic and infrasound signals which were recorded at numerous stations at ranges from ∼9 to over 600 km. Both avalanches initiated in the same location near the head of Iliamna's east-facing Red Glacier, and their ∼8 km long runout shapes are nearly identical. This repeatability – which is rare for large and rapid mass movements – provides an excellent opportunity for comparison and validation of seismoacoustic source characteristics. For both events, we invert long-period (15–80 s) seismic signals to obtain a force-time representation of the source. We model the avalanche as a sliding block which exerts a spatially static point force on the Earth. We use this force-time function to derive constraints on avalanche acceleration, velocity, and directionality, which are compatible with satellite imagery and observed terrain features. Our inversion results suggest that the avalanches reached speeds exceeding 70 m s−1, consistent with numerical modeling from previous Iliamna studies. We lack sufficient local infrasound data to test an acoustic source model for these processes. However, the acoustic data suggest that infrasound from these avalanches is produced after the mass movement regime transitions from cohesive block-type failure to granular and turbulent flow – little to no infrasound is generated by the initial failure. At Iliamna, synthesis of advanced numerical flow models and more detailed ground observations combined with increased geophysical station coverage could yield significant gains in our understanding of these events.
Evaluating participants' experience of extended interaction with cutting-edge physics research through the PRiSE “research in schools” programme
Authors: Archer Martin O. , DeWitt Jennifer , Thorley Charlotte , Keenan Olivia
Published: April 2021

Abstract. Physics in schools is distinctly different from, and struggles to
capture the excitement of, university research-level work. Initiatives
where students engage in independent research linked to cutting-edge
physics within their school over several months might help mitigate
this, potentially facilitating the uptake of science in higher education.
However, how such initiatives are best supported remains unclear and
understudied. This paper evaluates a provision framework, Physics Research in School Environments (PRiSE), using survey data from participating
14–18-year-old students and their teachers to understand their experience of the programme. The results show that PRiSE appears to provide much
more positive experiences than typical university outreach initiatives
due to the nature of the opportunities afforded over several months,
which schools would not be able to provide without external input.
The intensive support offered is deemed necessary, with all elements
appearing equally important. Based on additional feedback from independent
researchers and engagement professionals, we also suggest the framework
could be adopted at other institutions and applied to their own areas
of scientific research, something which has already started to occur.
Medusa–Aqua system: simultaneous measurement and evaluation of novel potential halogenated transient tracers HCFCs, HFCs, and PFCs in the ocean
Authors: Li Pingyang , Tanhua Toste
Published: April 2021

Abstract. This study evaluates the potential usefulness of the halogenated compounds
HCFC-22, HCFC-141b, HCFC-142b, HFC-134a, HFC-125, HFC-23, PFC-14, and PFC-116
as oceanographic transient tracers to better constrain ocean ventilation
processes. We do this mainly in terms of four aspects of the characteristics of the
potential tracers: input function (including atmospheric history and
historical surface saturation), seawater solubility, feasibility of
measurement, and stability in seawater; of these, atmospheric history and
seawater solubility have been investigated in previous work. For the latter
two aspects, we collected seawater samples and modified an established
analytical technique for the Medusa–Aqua system to simultaneously measure
these compounds. HCFC-22, HCFC-141b, HCFC-142b, HFC-134a, and HFC-125 have
been measured in depth profiles in the Mediterranean Sea for the first time
and for reproducibility in the Baltic Sea. We found that the historical surface
saturation of halogenated transient tracers in the Mediterranean Sea is
estimated to have been nearly constant at 94 % based on historical data.
Of the investigated compounds, HCFC-142b, HCFC-141b, and HFC-134a are found
to currently be the most promising transient tracers in the ocean. The
compounds that have the greatest potential as future tracers are PFC-14 and
PFC-116, mainly hampered by the low solubility in seawater that creates
challenging analytical conditions, i.e., low concentrations. HCFC-22 is
found to be likely unstable in warm seawater, which compromises the
potential as an oceanic transient tracer, although it is possibly useful in
colder water. For the compounds HFC-125 and HFC-23, we were not able to fully
evaluate their potential as tracers due to inconclusive results,
especially regarding their solubility and stability in seawater, but also with
regard to potential analytical challenges. On the other hand, HFC-125,
HFC-23, and HCFC-22 might not need to be considered because there are
alternative tracers with similar input histories that are better suited as
transient tracers.
Third-party funding na arbitragem contra Estados: a relativização da imunidade executória na execução da sentença arbitral contra Estados
Authors: Monteiro Ana , Ferreira Daniel
Published: April 2021

The purpose of this article is to assess the risk for preventing the execution of arbitral awards made against Sovereign States due to the State’s immunity shield. Given the importance of an accurate asset pricing in the business of third-party funding (TPF), the topic entails a particular relevance to the current context of globalized litigation in light of its contribution to the promotion of TPF at the international arbitration community. After reviewing the literature on TPF, on the peculiarities of investment and commercial arbitrations against States and on the evolution of State immunity (also in terms of domestic legislation, considering the local laws passed by the United States, the United Kingdom and Australia), the article aims explore how the funder should incorporate into its risk assessment the risk of not executing awards rendered against Sovereign States.

The alternative dispute resolution system in Italy: between harmonization with the requirements of European markets and de-juridicalization
Authors: D'Alessandro Giampiero
Published: April 2021

The topic of Alternative Dispute Resolution is comprehensively presented in Italy because of two different demands. The first is a demand presented at the European level to adopt measures that are meant to align the legal and regulatory provisions of different member States, even through the development of alternative methods for dispute resolution, in order to guarantee better access to justice at large, and this can be done through the use of supplemental and alternative dispute resolution methods which are of equal dignity to court proceedings. The second demand is presented at the national level and aims respond to the slowness of local court proceedings through so-called de-juridicalization, where legislations pertaining to A.D.R were supplemented with emergency measures that now include alternative tools among them. This complex tableau led to the creation of very detailed tools for dispute resolution on the civil front, tools that were often borrowed from foreign experiences. This paper wishes to offer a general framework of the principal players, without necessarily being exhaustive. In fact, in addition to Arbitration, which finds its origins in the Civil Code, Italian regulators have added over time procedures for civil and commercial mediation, assisted negotiation, settlement procedures for overindebtedness crisis and mediation on matters of energy and telecommunications and, more in general, on consumer matters. Some of these tools take on a principally deflationary function on matters of civil disputes where these same tools are considered necessary and constitute a condition of admissibility to be able to start legal proceedings. Faced with this complex tableau, in 2016 the Italian Ministry of Justice established a research committee, composed of professors, judges, lawyers and notaries who were entrusted with the task reassessing organically the matter with the aim of developing “de-juridicalization” tools using mediation, assisted negotiations and arbitration. In January 2017, this Commission, at the end of its tenure, presented a series of proposal to modify the legislation that was then in force. These proposals are to this day still under consideration by the Ministry of Justice. The establishment of the aforementioned Commission seemed justified because of the imminent termination of the implementation period for the compulsory mediation required by law for some disputes on civil and commercial matters, pursuant to Article 5, para. 1-bis, of Legal Decree 28/20106 that, instead, found a solution after changes made to convert Legislative Decree No. 50, April 24, 2017,7 through the so-called corrective action of 2017, into Law No. 96 of June 21, 2017.

Range of Motion to Impingement Curves Create a New Patient-Specific Impingement-Free Zone for Acetabular Cup Placement
Authors: McCarthy Thomas , Thompson Matthew , Nevelos Jim , Salem Hytham , Naylor Brandon , Mont Michael
Published: April 2021

Introduction: The acetabular “safe zone” has recently been questioned as a reliable reference for predicting total hip arthroplasty impingement and instability as many dislocations occur within the described parameters. Recently, an improved understanding of spino-pelvic mechanics has provided surgeons useful information to both identify those at a higher risk of dislocation and, in some cases, allows altering component positioning to accommodate the patient’s individual “functional” range of motion. The purpose of this study was to create a new patient-specific impingement-free zone by considering range of motion (ROM) to prosthetic impingement for both high flexion and extension poses, thus demarcating a zone that avoids both anterior and posterior impingement, thereby creating an objective approach to identifying a patient’s ideal functional safe zone.
Materials and Methods: A validated hip ROM three-dimensional simulator was utilized to create ROM-to-impingement curves for both high flexion as well as pivot and turn poses. The user imported a computerized tomography (CT) with a supine pelvic tilt (PT) value of zero and implant models (tapered wedge stem, 132° neck angle, 15° stem version, 36mm femoral head). Femur-to-pelvis relative motions were determined for three upright seated poses (femur flexed at 90° and 40° internal rotation, with 0°, 10°, and 20° posterior PT), one chair rise pose (femur flexed at 90° and 0° internal rotation, with the pelvis flexed anteriorly until the pelvis made contact with the femur), and three standing pivot and turn poses (femur set at 5° extension, and 35° external rotation, with 5° posterior PT, 0°, and 5° anterior PT). ROM-to-impingement curves for cup inclination versus anteversion were graphed and compared against the Lewinnek safe zone.
Results: The ROM-to-impingement curves provide an objective assessment of potential impingement sites as they relate to femoral rotation and pelvic tilt. The area between the stand and sit curves is the impingement-free area. A sitting erect pose with a simulated stiff spine (0° PT) yielded less impingement-free combinations of cup inclination and version than poses with greater than 0° posterior pelvic tilt.
Conclusion: The results demonstrate that the acetabular target zone has a relatively small margin for error between the sitting and standing ROM curves to impingement. Importantly, anterior and posterior pelvic tilt can markedly increase the risk of impingement, potentially leading to posterior or anterior dislocations, respectively. This study highlights the importance of correctly identifying the patient-specific functional range of motion to execute optimal component positioning.

Published: April 2021

Autologous keratinocyte culture, and combinations of scaffolds, different cell types, solutions of macromolecules, or growth factors have contributed to the resurfacing of full-thickness skin defects. Ideally, a treatment for full-thickness skin defects should not merely reestablish continuity of the surface of the skin but should restore its structure to allow skin to function as a dynamic biological factory that can participate in protein synthesis, metabolism, and cell signaling, and form an essential part of the body’s immune, nervous, and endocrine systems. This paper provides a review of clinically available autologous skin replacements, highlighting the importance of regenerating an organ that will function physiologically.

The collapse of the Soviet Empire and the dizzying development of new communication technologies, led to the geopolitical reconfiguration of the world, but also opened the way for the former Soviet republics to democracy and collaboration with European countries. As NATO and the EU advance towards Russia’s borders, it makes both military and ideological propaganda efforts to keep the territories of the past under its influence. Not without the competition of Russia in the countries of the “close neighborhood”- Ukraine, the Republic Of Moldova and Georgia were inspired conflicts, called to preserve military, political, ideological and economic control over these regions. A fierce battle is also waging by Russia for the strengthening of its positions in the Black Sea region, where geoprafically Ukraine, the Republic Of Moldova and Georgia are located. The article highlights the strategies, tactics and techniques applied by the Russian media in order to achieve geopolitical goals.

Physico-Chemical Analysis of Gunja Tail and Its Conversion into Shampoo
Authors: Abdul Wakeel Dr Saba Shaheen
Published: April 2021

ABSTRACT:
Shampoo in simple terms is a hair care product designed to clean the scalp skin along with its hairs. Incidentally, the term shampoo entered the English language through the Hindi word â€œchampooâ€ was used meaning to press or massage; it was used to denote cleaning through massage of the hair and skin [1]. Todayâ€™s shampoo formulations are beyond the stage of pure cleaning of the hair. Additional benefits are expected, e.g., conditioning, smoothing of the hair surface, good health of hair, i.e., hair free of dandruff, dirt, grease and lice and, above all, its safety benefits are expected. In the present scenario, it seems improbable that herbal shampoo, although better in performance and safer than the synthetic ones, will be popular with the consumers. The present study is about the preparation of Gunja shampoo and its comparative Physico-chemical study with the Gunja oil. Ayurvedic literature name Chakradatta Samhita had explained Gunja tail in Kandu rogadhikar, in this study conversion of tail will be done by shampoo as it is easily acquired by society.
