A arbitragem e a teoria do direito e desenvolvimento: uma breve análise sobre a experiência da arbitragem marítima de Singapura e do Brasil

The rule of Law and the pursuit of economic development is an undeniable fact for all countries in XXI century. It could be noticed the interrelation between law and development by the impact that it causes on the country’s economy. To validate this hypothesis claimed by the Law & Development theory it should have more survey about this topic. Due to this aim, the present research is intended to examine the contribution of arbitration in the development of the international trade in Singapore and Brazil. A qualitative approach was used to produce this research as well as the documentary one. Among the results obtained it could be established that arbitration plays a strategic role in the economic development policies for international trade scene.As discussões sobre o desenvolvimento na atualidade possuem caráter interdisciplinar, com reflexo inclusive na ciência do Direito, fato este evidenciado pela teoria do Direito e Desenvolvimento a qual afirma que os institutos jurídicos influenciam o processo de desenvolvimento dos países. Tal teoria ainda não goza de autonomia metodológica, sendo necessárias mais pesquisas empíricas para validar seus modelos. Neste sentido o presente artigo tem como proposta a realização de uma breve análise acerca da experiência de utilização do instituto jurídico da arbitragem especializada em Direito Marítimo como estratégia de desenvolvimento do comércio internacional em Singapura e no Brasil. Em relação aos objetivos específicos, a serem alcançados pode-se elencar: Identificar os elementos jurídicos determinantes para o desenvolvimento do comércio internacional, verificar os fatores que contribuíram para as reformas do instituto jurídico da arbitragem e compreender o impacto do instituto jurídico da arbitragem especializada em direito marítimo no comércio internacional dos países estudados. A metodologia utilizada foi à qualitativa no qual foi usada técnicas de pesquisa documental e bibliográfica. No tocante ao resultado foi verificado, dentre outros aspectos, que a arbitragem possui um papel estratégico no desenvolvimento de políticas econômicas voltada para o comércio internacional.

Nota introdutória [a] Cibercultura: circum-navegações em redes transculturais de conhecimento, arquivos e pensamento

neste quadro que decidimos organizar, em outubro de 2016, na Universidade do Minho, um congresso então intitulado: Cibercultura. Circum-navegações em Redes Transculturais de Conhecimento, Arquivos e Pensamento. Tal iniciativa foi na altura motivada pela profunda convicção de que a cibercultura é, na contemporaneidade, uma área científica fundamental a dois níveis: ao nível dos projetos de ensino, na sua articulação com os mais diversos cursos e diferentes disciplinas, e ao nível da investigação. Definitivamente impregnada na nossa experiência quotidiana, a tecnologia torna-se cada vez mais “transparente” nos seus modos de atuação, ao mesmo tempo que “invisível”, dada a progressiva desmaterialização dos dispositivos com os quais coabitamos, co-agimos, co-pensamos, co-sentimos. A título ilustrativo, podemos referir os avanços na eliminação da separação entre o corpo próprio, o corpo orgânico, e os objetos tecnológicos, através quer das possibilidades da ciberciência, dos implantes, das próteses, da criação do corpo- -híbrido, quer por meio da sofisticação dos andróides, nomeadamente no campo da robótica. Erica, por exemplo, “a mais perfeita andróide” recentemente criada por Hiroshi Ishiguro, no Japão, apresenta-se surpreendentemente “humanizada”, não só dado o seu aspeto, muito similar ao dos humanos, mas também pelas suas capacidades interlocutivas. A adoção deste tipo de humanoides tendo por fim, simplesmente, a companhia em ambiente doméstico, sobretudo em sociedades envelhecidas como é o caso do Japão, é já considerável. Por outro lado, a robotização massiva no contexto da produção industrial, para a qual tendem os grandes grupos multinacionais, é uma realidade. Impõe-se, pois, a urgência de refletir, tanto nas escolas e nas universidades, como nos múltiplos fóruns da esfera pública, sobre este e outros tipos de fenómenos, sobre as nossas práticas do dia-a- -dia, sobre as mudanças nas experiências e nas representações do conhecimento e do mundo, mas também sobre as perceções do (second)self. São infindáveis as questões, de natureza filosófica, epistemológica, ontológica, pragmática, política, económica, social que a nossa relação com as tecnologias agenciam. Identificar algumas dessas inquietações, discuti-las e perspetivá-las à luz das condições e das experiências da atualidade, é o principal propósito desta publicação. Tendo por fim esse mesmo objetivo, foram reunidos textos dos participantes no já referido Congresso, os quais se organizam em duas secções que passaremos a apresentar.info:eu-repo/semantics/publishedVersio

Bonding of universal adhesive system to enamel surrounding real-life carious cavities

This study aimed to evaluate the bond strength of a universal adhesive system to enamel surrounding real-life carious cavities. Twentyeight permanent molars (n = 7) with carious lesions in dentin were subjected to selective carious tissue removal to firm dentin and had their crowns sectioned longitudinally. A universal adhesive system (Single Bond Universal [SBU] used in either etch-and-rinse and self-etch strategies) was compared with an etch-and-rinse Adper Single Bond 2 (ASB) and a selfetch Clearfil SE Bond (CSE) adhesive systems (control systems). Adhesives were applied on the enamel, assumed demineralized, surrounding the cavity margins and on sound enamel (control substrate). Composite cylinders were built (0.72 mm2) and microshear bond strength (μSBS) test was performed after 24 h of water storage. The μSBS values (MPa) were analyzed using two-way ANOVA and Tukey’s post hoc tests (α = 0.05). Bond strength values obtained in demineralized enamel surrounding carious cavity margins were significantly lower than that obtained in sound enamel (distant from carious cavity margins) (p = 0.035). The bonding strategy of the SBU did not influenced the bond strength values, which were higher than that obtained with ASB. CSE showed similar μSBS values to ASB and SBU in the self-etch mode. In conclusion, the bond strength to enamel assumed demineralized is lower than to sound enamel. The enamel surrounding carious cavities jeopardize the bonding of universal adhesive system. The bond strength of universal adhesive is similar, regardless to bonding strategy

Dental stem cells and tissue regeneration in odontology: a brief systematic review

Introduction: New ideas for tooth and tissue regeneration began to appear with rapid developments in tissue engineering theories and technologies. Numerous types of stem cells have been isolated from dental tissue, such as dental pulp stem cells (DPSC), human pulp stem cells isolated from exfoliated primary teeth (SHED), periodontal ligament stem cells (PDLSC), apical papillary stem (SCAP) and dental follicular cells (DFC). All these cells can regenerate tooth tissue. Objective: It was to present the main considerations of bioengineering techniques and report the results obtained in experiments with dental stem cells, as well as their real trends in application in dentistry. Methods: The systematic review rules of the PRISMA Platform were followed. The search was carried out from October to December 2022 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases, using articles from 2001 to 2022. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed accordingly, according to the Cochrane instrument. Results and Conclusion: A total of 118 articles were found, 27 articles were evaluated and 16 were included and developed in this systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 29 studies with a high risk of bias and 42 studies that did not meet GRADE. It is concluded that the collection of mesenchymal stem cells from deciduous teeth should be widely disseminated, as it is of great importance and wide applicability, allowing the repair of the most diverse cell types. In addition, it has several advantages, such as a non-invasive technique, respecting the period of dentition change, there are more than 20 collection possibilities, it presents high compatibility with the donor and family members and storage for an indefinite period. The studies showed that implantation of stem cells from deciduous teeth led to the regeneration of three-dimensional pulp tissue equipped with blood vessels and sensory nerves up to 12 months after treatment, as well as increased root length and reduced apical foramen width, not showing adverse events over 24 months of follow-up

Volatilização de amônia de ureias protegidas na cultura do cafeeiro conilon

Among the sources of nitrogen (N) used in agriculture urea is the most widely used fertilizer in Brazil. However, this source presents problems with the application on the soil surface due to N losses by NH3 volatilisation, resulting from the action of the enzyme urease. This study aimed to determine the losses of nitrogen (N) by Ammonia volatilisation and yield of Conilon coffee plants fertilized with protected ureas. The experiment was installed in Nova Venécia – Espírito Santo state, Brazil, in commercial coffee farming Conilon ‘Vitória INCAPER 8142’ with five sources of nitrogen fertilizers: Common Urea-45% N (UC45), Urea-45% N + NBPT (U45+NBPT), Urea-44.6% N + 0.15% Cu + 0.4 % B (U44.6+Cu+B); Urea-37% N + 17% de S (U37+S), and Ammonium Nitrate-34% N (AN34). The experimental design was randomized blocks with five treatments and six replicates. Ammonia collectors were installed in each plot immediately after fertilizer application. Ureas protected by NBPT inhibitor and the Cu + B micronutrients have lower volatilisation losses in relation to unprotected urea. The coating of urea with sulfur does not provide reduced losses of N by volatilisation. The coffee yield is not affected by the use of protected ureas with NBPT, Cu + B and S under the conditions studied.Dentre as fontes de nitrogênio utilizadas na agricultura, a ureia é o fertilizante mais utilizado no Brasil. Todavia, apresenta problemas com a aplicação na superfície do solo devido às perdas de N por volatilização de amônia, decorrentes da ação da enzima urease. Objetivou-se determinar as perdas de N por volatilização de amônia de ureias protegidas e a produtividade de plantas de cafeeiro adubadas com tais fertilizantes. O experimento foi instalado em Nova Venécia – ES, em lavoura comercial de café Conilon ‘Vitória INCAPER8142’. Foram avaliadas cinco fontes de fertilizantes nitrogenados: T1= Ureia comum (45 % N); T2= Ureia (45 % N) + NBPT; T3= ureia (44,6 % N) +0,15% de Cu + 0,4 % de B; T4= ureia (37 % N) + enxofre (17 %); e T5= nitrato de amônio (34 % N). Foram instalados coletores de amônia, em cada parcela experimental, imediatamente após a aplicação dos fertilizantes. As ureias protegidas pelo inibidor NBPT e pelos micronutrientes Cu + B apresentam as menores perdas por volatilização que a ureia não protegida. O recobrimento da ureia com enxofre não proporciona redução das perdas de N por volatilização de amônia. A produtividade dos cafeeiros não é afetada pela utilização de ureias protegidas com NBPT, Cu + B e S, sob as condições estudadas

Fertigation of arugula crops grown in saline soils

Arugula is a leafy vegetable that has been standing out in terms of consumption due to its nutritional content. The crop has low tolerance to water salinity (ECw), and information on the management of fertilization in saline environments is scarce. In this context, this study aimed to analyze the nutritional aspects of arugula under different soil salinity levels and fertilization doses via fertigation. The experiment was conducted in a greenhouse during two production cycles in 2021 in a randomized block design and a 4 x 3 factorial arrangement, with four replications. The treatments consisted of four soil salinity levels (ECse = 0.57, 1.3, 2.3, and 3.3 dS m−1) and three doses of a mineral fertilizer based on the recommended fertilization via fertigation (F1 = 100%, F2 = 50%, and F3 = 25%). The contents of N, P, K, Ca, Mg, S, Na, Cu, Fe, Zn, and Mn were evaluated after harvesting. Salinity directly affected the concentration of mineral elements in arugula leaf during the first cycle, mainly Ca, Mg, Zn, and Mn. The fertigation strategy with 100% of the recommended fertilization showed better results than the other doses for N, P, K, and S. In the second cycle, all elements showed a reduction due to the high ECse, mainly the value of 3.3 dS m−1. The fertigation strategy that used 100% of the recommended fertilization promoted higher nutrient accumulation in arugula. The order of nutrient accumulation in arugula leaf was K>N>Ca>S>Mg>P>Fe>Zn>Mn>Cu.Arugula is a leafy vegetable that has been standing out in terms of consumption due to its nutritional content.

Fluorescência transiente da clorofila a e crescimento vegetativo em cafeeiro conilon sob diferentes fontes nitrogenadas

The use of nitrogen fertilizers is an effective resource to increase the coffee yield, so that the improvement and /or generation of new techniques that assist in the management of nitrogen fertilization are essential, as will contribute to increase nitrogen use efficiency (N). Thus, this study aimed to determine the chlorophyll a fluorescence transient and vegetative growth in Conilon coffee under different nitrogen sources. The experiment was carried out in Nova Venécia - ES - Brazil, on coffee plantation Conilon cultivar “Vitória Incaper 8142”. Were evaluated five sources of nitrogen fertilizers: urea common, urea + NBPT, urea + Cu and B, urea + S, and ammonia nitrate. The chlorophyll a fluorescence maximum did not differ in any of the times examined. The values of relative chlorophyll index (RCI) alternated their significance with respect to treatments throughout the evaluation dates. The N sources were not responsible, singly, with changes to the RCI. The sources of nitrogen fertilizers with increased efficiency exhibited low influence on transient fluorescence of chlorophyll a and do not influence the vegetative growth of the coffee.O uso de fertilizantes nitrogenados é um recurso eficaz para elevar a produtividade do cafeeiro, de modo que o aprimoramento e/ou geração de novas técnicas que auxiliem no manejo da adubação nitrogenada são fundamentais, pois contribuirão para aumentar a eficiência de uso do nitrogênio (N). Dessa forma, objetivou-se determinar a fluorescência transiente da clorofila a e o crescimento vegetativo do cafeeiro Conilon sob diferentes fontes nitrogenadas. O experimento foi realizado em Nova Venécia - ES - Brasil, em lavoura de café Conilon cultivar “Vitória Incaper 8142”. Foram avaliadas cinco fontes de adubos nitrogenados: ureia comum, ureia + NBPT, ureia + Cu e B, ureia + S, e nitrato de amônio. A fluorescência máxima da clorofila a não diferiu em nenhuma das épocas analisadas. Os valores de índice relativo de clorofila (IRC) alternaram suas significâncias com relação aos tratamentos ao longo das datas de avaliação. As fontes de N não foram responsáveis, isoladamente, pelas alterações do IRC. As fontes de fertilizantes nitrogenados de eficiência aumentada apresentam baixa influência na fluorescência transiente da clorofila a e não influenciam o crescimento vegetativo do cafeeiro

Adverse reactions to the injection of face and neck aesthetic filling materials:a systematic review

Adverse reactions, caused during the inflammation and healing process, or even later, can be induced by the injection of dermal filler and can present a variety of clinical and histological characteristics. In this study we aimed to review the adverse reactions associated with the injection of aesthetic filling materials in the face and neck. The review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Studies published that mentioned adverse reactions in patients with aesthetic filling materials in the face or neck were included. Risk of bias was assessed using the Joanna Briggs Institute appraisal tool. After a 2-step selection process, 74 studies were included: 51 case reports, 18 serial cases, and five cohorts. A total of 303 patients from 20 countries were assessed. Lesions were more prevalent in the lip (18%), nasolabial folds (13%), cheeks (13%), chin (10%), submental (8%), glabella (7%), and forehead (6%). Histopathological analysis revealed a foreign body granuloma in 87.1% of the patients, 3% inflammatory granuloma, 3% lipogranuloma, 2.3% xanthelasma-like reaction, 1% fibrotic reaction, 0.7% amorphous tissues, 0.7% xanthelasma, 0.3% sclerosing lipogranuloma, 0.3% siliconoma, and 0.3% foreign body granuloma with scleromyxedema. In addition, two patients displayed keratoacanthoma and two others displayed sarcoidosis after cutaneous filling. The most commonly used materials were silicone fillers (19.7%), hyaluronic acid (15.5%), and hydroxyethyl methacrylate/ethyl methacrylate suspended in hyaluronic acid acrylic hydrogel (5.6%). All patients were treated, and only 12 had prolonged complications. There is evidence that adverse reaction can be caused by different fillers in specific sites on the face. Although foreign body granuloma was the most common, other adverse lesions were diagnosed, exacerbating systemic diseases. In this way, we reinforce the importance of previous systemic evaluations and histopathological analyses for the correct diagnosis of lesions
