Authors: Tieni Lucas Arruda , Pigozzo Julio César , Wutzow Wilson Wesley , Silva Leonardo Martins e , Christoforo André Luis
Published: February 2021

A grelha lamelar em madeira permite a construção de grandes vãos com uso de madeira serrada em dimensões comerciais. O sistema é caracterizado pela geometria das barras, em que cada nó reúne o centro de uma barra (contínua ou não) com as extremidades de duas outras, cada uma destas barras representando uma lamela. Dependendo da concepção das ligações definidas entre as lamelas, a transmissão dos momentos de torção pode ou não ser levada em consideração, e tal condição pode impactar significativamente no desempenho mecânico da estrutura lamelar a ser projetada (maior ou menor rigidez frente à ação das cargas). O objetivo deste trabalho é analisar modelos numéricos de estruturas de grelha lamelar variando a vinculação entre as barras, contribuindo assim para o desenvolvimento de projetos estruturais baseados em simulações mais realistas de estruturas lamelares de madeira. Os elementos de barra podem ou não transmitir momentos de torção em suas extremidades. Portanto, são comparados os resultados de modelos numéricos à evidências experimentais, oriundas de um protótipo de grelha lamelar plana feito com madeira de Pinus spp. A variável utilizada para as comparações é o deslocamento vertical em vários pontos da estrutura. O modelo numérico é elaborado e analisado no software SAP2000. Mantém-se a estrutura em condições tais que não ultrapassem o estado limite de utilização. As ligações entre as lamelas foram feitas com chapas metálicas que envolvem lateralmente a lamela, fixadas às barras de madeira por parafusos auto atarraxantes. Pelos resultados obtidos, o modelo considerando articulação perfeita forneceu deslocamentos nodais mais próximos dos deslocamentos obtidos experimentalmente, indicando ser pequena a torção transmitida entre as barras.
ROCKFALL HAZARD ASSESSMENT AND GEOLOGICAL-GEOTECHNICAL CHARACTERIZATION OF A ROCK SLOPE IN BR-356
Authors: Da Silva Denise de Fátima Santos , Santos Allan Erlikhman Medeiros
Published: February 2021

The rockfall hazard assessment for roads is very important in geotechnical engineering business. As the process is very fast and complex, a hazard analysis is of fundamental importance for the adoption of preventive action plans and mitigation of potential impacts. Therefore, this article presents a hazard analysis for rockfall and the geological-geotechnical characterization of a rock slope on the BR-356, Ouro Preto, Minas Gerais, Brazil. In the methodology, parameters related to the geotechnical characterization, geometry and slope characteristics were inserted, as signs of block fall activity, impact of external influences and characteristics of the catchment area. According to Rock Mass Rating (RMR), the rock slope was classified as Very Good (Class I). The hazard classification for the slope analyzed varies from low to high. When the rainfall of the rainy season is considered, the slope is classified as a high hazard, while in the dry season, it is classified as low hazard. The study revealed that even if the hazard class is low, the slope deserves attention, since there is not enough space for rock blocks to be deposited before reaching the road, which can generate damages and temporarily paralyze the activities of the road.
COVO RECICLADO: NOVO MODELO DE ARMADILHA DE PESCA PARA MINIMIZAR OS CONFLITOS ENTRE A LONTRA E OS PESCADORES

Published: February 2021

São várias as espécies de mustelídeos que interagem com populações pesqueiras por todo o mundo, porém, são poucos os estudos que abordam o tema no Brasil. Este é o segundo estudo que enfoca os conflitos entre a Lontra longicaudis (Olfers, 1818 - Ordem: Carnivora; Família: Mustelidae; Subfamília: Lutrinae) com a população pesqueira da APA Bonfim Guaraira, localizada no Estado do Rio Grande do Norte. Foram entrevistadas cinco comunidades que ainda realizam a atividade de pesca com covos artesanais em diferentes municípios. A principal preocupação apontada pelos pescadores foi o interesse da L. longicaudis sobre os covos utilizados para pesca de camarão de rio Macrobrachium sp. (Ordem: Decapoda; Família: Palaemonidae) que estão periodicamente sendo quebrados pela lontra, ademais os covos são confeccionados com materiais oriundos da vegetação in locu. Portanto, o objetivo deste trabalho é apresentar uma solução para melhorar os apetrechos (covos) dos pescadores, através da reciclagem com canos de PVC. O covo produzido foi um sucesso para a pesca artesanal e também gerou subsídios para conservação da L. longicaudis. Apesar da constante perseguição na região, é possível constatar que a grande maioria dos pescadores pensam de maneira diferente, compreendendo que as lontras, assim como eles, também dependem do camarão, do peixe e do rio para sobreviver, neste processo novas ideias foram estimuladas entre os demais pescadores para diminuir este conflito.

Authors: Lamounier Kenia F , Pasquini Daniel , Rodrigues Patrisia O , Soares Alexandre S , Baffi Milla A
Published: February 2021

In this study, the enzymatic saccharification of alkaline pretreated sugarcane bagasse (PSB) and the production of second generation bioethanol were investigated under different conditions. The effects of percentage of dry substrate (3 and 10% w/v) and time of hydrolysis (24 and 72 h) were evaluated in order to obtain maximum contents of total reducing sugar (TRS), glucose and xylose. The monosaccharide concentrations were quantified by High Performance Liquid Chromatography (HPLC) and TRS by the 3.5-dinitrosalicylic acid (DNS) method. The saccharification of PSB with the Cellic Ctec3, promoted an efficient release of sugars. Among the four evaluated conditions, the hydrolysis HD (10% PSB and 72h) was selected as the most efficient with the highest concentrations of released sugars: TRS (73.96 g/L), glucose (31.78 g/L) and xylose (10.85 g/L). The alcoholic fermentation of hydrolysate HD with the yeast Saccharomyces cerevisiae produced the maximum concentration of 16.15 g/L of ethanol, with a volumetric productivity (QP) of 0.69 g/Lh and yield of ethanol as a function of the substrate (YP/S) of 0.48 gethanol/gsugar. S. cerevisiae was capable of fermenting 99.96% of glucose from hydrolysate HD. These results suggest that the increase of the substrate load and time in the enzymatic hydrolysis can be favourable alternatives to improve the sugar yields in hydrolysates and, consequently, the bioethanol production.

Authors: Moreira Eliani Jordana da Silva , Bertini Luciana Medeiros
Published: February 2021

A efetiva melhoria do processo de ensino e aprendizagem ocorre pela intervenção do professor e pelo contínuo aprimoramento sobre sua prática pedagógica em ações de educação inicial e continuada. Assim, o meio escolar é um ambiente propício à pesquisa e à investigação do potencial de diferentes metodologias. Nesse sentido, as Unidades de Ensino Potencialmente Significativas (UEPS) – sequências de ensino fundamentadas teoricamente – estão voltadas para a aprendizagem significativa, uma vez que podem estimular a pesquisa aplicada em ensino, aquela voltada diretamente à sala de aula. Neste trabalho são apresentados resultados da análise do uso das UEPS, através de uma oficina pedagógica, para estudantes do curso de Licenciatura em Química com o intuito de avaliar em que medida a estratégia pode ser vista por estes para abordar conteúdos químicos. Adotamos neste trabalho a pesquisa quantitativa, com o uso da escala de Likert e qualitativa, a partir da pesquisa ativa, na forma de pesquisa-ação. Os dados quantitativos foram tratados segundo a estatística clássica, usando como medidas de centralidade, a média aritmética e desvio padrão. Com isso, o objetivo foi apresentar aos futuros docentes uma estratégia de ensino diferenciada, que possibilite uma aprendizagem significativa e analisar de que maneira a estratégia foi percebida por estes. Após a avaliação da ação, foi possível compreender que os discentes perceberam as UEPS como interessantes para serem utilizadas em suas aulas. Entretanto, foram consideradas pouco viáveis, em virtude de aspectos relacionados ao tempo destinado à sua preparação e ao não conhecimento da estratégia.
AVALIAÇÃO DO DESEMPENHO TÉCNICO DE DIFERENTES MISTURAS DE SOLO COM RESÍDUOS DE CONSTRUÇÃO (RCD) PARA USO EM OBRAS VIÁRIAS
Authors: BARRETO ALISSON CABRAL , AMORIM ENIO FERNANDES
Published: February 2021

O processo de urbanização tem provocado um aumento na construção civil e, consequentemente, aumento na geração de resíduos. O resíduo de construção e demolição (RCD) representa grande parcela do volume de resíduos que são gerados em grandes centros urbanos, sendo necessária uma destinação adequada para mitigar os impactos ambientais e os problemas sociais que são gerados. Diante deste contexto, este artigo tem como objetivo analisar o uso do RCD associado a diferentes tipos de solos, adicionando ao solo porcentagens de RCD de 25%, 50% e 75%, em massa, visando o seu emprego em obras de pavimentação. O programa experimental foi realizado a partir de amostras de RCD obtidas por uma empresa privada e amostras de solos extraídas de três grandes regiões do estado do Rio Grande do Norte. Os métodos de investigação de laboratório basearam-se nos ensaios de caracterização física, compactação, CBR e análise de quebra dos grãos. Os resultados obtidos mostram que dependendo da porcentagem de resíduo e do tipo de solo, o incremento de RCD ao solo faz com que os valores do CBR se elevem e melhorem as propriedades das amostras. Deste modo, a substituição de parte do agregado natural por RCD é uma potencial alternativa para aplicação em obras de pavimentos.

Published: February 2021

Battery management systems are used to monitor power batteries in electric vehicles and solar power systems. They control the charge and discharge, identity and correct many problems in these batteries. Nowadays, measurements on each cell or stack of cells, which compose the battery, are necessary to ensure the safety and integrity of the system, because the battery cells degrade unequally since they are not built identically. A new methodology is presented in this work, for identification cells with finished life cycle in batteries parallel cells associations, without using temperature measurements, cell monitoring and State of Health estimators, through Support Vector Machines and Wavelet Transform. The proposed method opens possibilities for a new strategy of battery management in electric vehicles, inserting Battery Management System  in the charging stations and allowing more sophisticated diagnoses.

Published: February 2021

No litoral oriental do Estado do Rio Grande do Norte, há a presença de campos de dunas transgressivos, surgidos a partir do transporte e deposição de sedimentos pela ação eólica. Nas áreas mais baixas há o afloramento da superfície freática, o que dá origem às lagoas interdunares. A Área de Proteção Ambiental de Jenipabu (APAJ) comporta um desses campos de dunas transgressivos, onde ocorrem algumas destas lagoas. Estes depósitos são relevantes, seja no contexto ecossistêmico, por abrigar grande diversidade de organismos e corpos d’água potável (as lagoas interdunares), seja por sua atribuição paisagística e turística. Por isso, foi feito um estudo desses sedimentos, que consistiu em uma análise granulométrica e morfométrica, além de uma análise de correspondência múltipla, integrando todos os resultados. Foi possível conferir a composição mineralógica predominantemente quartzosa variando de cascalho à fração silte/argila. O ambiente possui grãos que estão principalmente na fração areia fina a média; moderadamente a bem selecionados, com esfericidade média amplamente dominante, característicos de ambientes de alta energia dinâmica.

EXPANSÃO DA EDUCAÇÃO SUPERIOR NO INSTITUTO FEDERAL DE EDUCAÇÃO, CIÊNCIA E TECNOLOGIA DA PARAÍBA: OS DELINEAMENTOS NO PERÍODO 2008-2015
Authors: Neto Antônio Cabral , Araújo Maize Sousa Virgolino de
Published: February 2021

O artigo tem por objetivo discutir o processo de expansão da educação superior no Instituto Federal de Educação, Ciência e Tecnologia da Paraíba (IFPB), verticalizando a análise em três dos seus maiores campi (João Pessoa, Campina Grande e Sousa). Para viabilizar a análise da temática foram utilizadas informações registradas em documentos oficiais do período 2008-2015 e dados disponíveis no sítio da instituição sobre o processo de expansão da Educação Superior. Conclui-se que o movimento de expansão do IFPB, em termos de ampliação no número de campi, proporcionou o alcance das metas estabelecidas nos três PDIs – de 2005, 2010 e 2015 –, viabilizando um crescimento de 600% no período de 2005-2015. Esse aumento do número de campi oportunizou a interiorização da rede de educação profissional e tecnológica na Paraíba. O movimento de expansão da graduação do IFPB, embora siga a lógica do novo padrão de modernização para a Educação Superior, incluso no novo paradigma de produção capitalista neoliberal que incentiva a adoção de mecanismos gerenciais e as parcerias com empresas privadas, contraditoriamente,  traz elementos de alcance social, pois a instituição permitiu uma ampliação substancial da oferta e da interiorização de cursos de Educação Superior em todo o estado da Paraíba para setores historicamente excluído desse nível educacional.

Flourishing systems: re-envisioning infrastructure as a platform for human flourishing
Authors: Schooling Jennifer , Enzer Mark , Broo Didem Gurdur
Published: February 2021

This paper describes how infrastructure should be considered a system of systems and its main purpose should be human flourishing. With this mindset, the paper underlines the importance of envisioning and managing infrastructure accordingly. We have created an amazing, complex machine on which we wholly depend. Without it, our lives would be immeasurably worse. Society would not survive. That machine is infrastructure – our built environment. However, we do not appreciate the relationship between the machine and our well-being. Therefore, we do not set objectives in terms of outcomes for people and society. Furthermore, although we understand each part of the machine, we do not manage it as a whole. Therefore, we do not know how to address its systemic vulnerabilities or make it work better. If we envision, plan and manage infrastructure differently, we can make it what it should truly be: a platform for human flourishing. This paper advocates a vision for infrastructure that is, firstly, people focused – recognising the fundamental role of infrastructure in the social, economic and environmental outcomes that determine the quality of people’s lives – and, secondly, systems based – recognising infrastructure as a complex, interconnected system of systems that must deliver continuous service to society. It articulates how the industry should re-envision itself to unlock greater value for people, from the systems.
Deformation behavior of high-entropy alloy system Al – Co – Cr – Fe – Ni achieved by wire-arc additive manufacturing
Authors: Ivanov Yu. F. , Osintsev K. A. , Gromov V. E. , Konovalov S. V. , Panchenko I. A.
Published: February 2021

A non-equiatomic high-entropy alloy (HEA) of the Al – Co – Cr – Fe – Ni system was obtained using wire-arc additive manufacturing technology in the atmosphere of pure argon. The initial wire had 3 conductors with different chemical composition: pure aluminum wire (Al ≈ 99.95 %), chromium-nickel wire (Cr ≈ 20 %, Ni ≈ 80 %), and cobalt alloy wire (Co ≈ 17 %, Fe ≈ 54 %, Ni ≈ 29 %). The resulting sample of high-entropy alloy was a parallelepiped consisting of 20 deposited layers in height and 4 layers in thickness. The alloy had the following elemental composition, detected by energy-dispersive X-ray spectroscopy: aluminum (35.67 ± 1.34 at. %), nickel (33.79 ± 0.46 at. %), iron (17.28 ± 1.83 at. %), chromium (8.28 ± 0.15 at. %) and cobalt (4.99 ± 0.09 at. %). Scanning electron microscopy revealed that the source material has a dendritic structure and contains particles of the second phase at grain boundaries. Element distribution maps obtained by mapping methods have shown that grain volumes are enriched in aluminum and nickel, while grain boundaries contain chromium and iron. Cobalt is distributed in the crystal lattice of the resulting HEA quasi-uniformly. It is shown that during tensile tests, the material was destroyed by the mechanism of intra-grain cleavage. The formation of brittle cracks along the boundaries and at the junctions of grain boundaries, i.e., in places containing inclusions of the second phases, is revealed. It was suggested that one of the reasons for the increased fragility of HEA, produced by wire-arc additive manufacturing, is revealed uneven distribution of elements in microstructure of the alloy and also the presence in material volume of discontinuities of various shapes and sizes.
Mass Media Information Validation Models for Decision Making

Published: February 2021

he authors study the mathematical models that formalize philosophical notions “information field” and “information” with mathematical means including Gauss’s theorem. They propose a radial hierarchy of information validation that reflects the taxonomic structure of factors affecting it. Besides, the authors work out a cognitive model that contributes to making scientifically based decisions concerning validity of information in the mass media. The model is tested with the help of simplicial analysis which enables to see unevident links between the factors influencing the formation of the structure of the cognitive model. Calculation procedures helped to correct the analyst’s speculations concerning the links between the factors in the cognitive model, applying the notion “coupling network”, which implies a connection between two separate simplexes through a network of intermediary simplexes.
The results of the study may add to executive decision-making when designing and implementing programs of ideological purpose.
Development of Investment Life Insurance in Russia
Authors: Rusakova Oksana , Golovan Sofia
Published: February 2021

Investment life insurance products appeared in the life insurance segment in the mid-70s of the last century and by the end of the decade, began to gain popularity in many countries (USA, Canada, Asia and Europe). Throughout its history of development, investment life insurance has experienced many ups and downs. Each financial crisis has had a negative impact on its development indicators. Despite this, interest in investment life insurance persists, as more and more potential policyholders want to use investments in various financial instruments in combination with insurance protection. At the same time, they agree to pay a higher insurance premium, being confident that they receive more for it than with traditional endowment life insurance. The article provides arguments in favor of the need for a legislative revision of restrictions on investment life insurance in order to increase its further attractiveness.

Dynamic Mapping of Probability of Default and Credit Ratings of Russian Banks
Authors: Khromova Ella
Published: February 2021

Investors are interested in a quantitative measure of banks’ credit risk. This paper maps the credit ratings of Russian banks to default probabilities for different time horizons by constructing an empirical dynamic calibration scale. As such, we construct a dynamic scale of credit risk calibration to the probability of default (PD).Our study is based on a random sample of 395 Russian banks (86 of which defaulted) for the period of 2007-2017. The scale proposed by this paper has three features which distinguish it from existing scales: dynamic nature (quarterly probability of default estimates), compatibility with all rating agencies (base scale credit ratings), and a focus on Russian banks.Our results indicate that banks with high ratings are more stable just after the rating assignment, while a speculative bank’s probability of default decreases over time. Hence, we conclude that investors should account for not only the current rating grade of a bank, but also how long ago it was assigned. As a result, a rising capital strategy was formulated: the better a bank’s credit rating, the shorter the investment horizon should be and the closer the date of investment should be to the rating assignment date in order to minimise credit risk.The scientific novelty of this paper arises from the process of calibration of a rating grade to dynamic PD in order to evaluate the optimal time horizon of investments into a bank in each rating class. In practical terms, investors may use this scale not only to obtain a desired credit rating, but also to identify quantitative measure of credit risk, which will help to plan investment strategies and to calculate expected losses.

Published: February 2021

This study evaluates the water quality for human consumption in the municipalities of Sincerín and Gambote. It was measured through physico-chemical (color, turbidity, conductivity, pH, dissolved oxygen, hardness, and heavy metals) and microbiological (total coliforms, Escherichia coli) parameters before and after a partial form of water treatment was used (alum and chlorine addition in Gambote and Sincerín municipalities, respectively).  This investigation was done in accordance with the maximum permissible values established by the Resolution 2115 of 2007 of the Ministry of Environment, Housing, and Territorial Development of Colombia (MAVD in Spanish). Additionally, the IRCA (Water Quality Risk Index) was calculated to determine the degree of risk of disease occurrence. The results indicated concentrations higher than the recommended values for: (a) hardness (in Sincerín); (b) iron (Fe), turbidity (only before being treated), E. coli (in Gambote); and (c) mercury (Hg), and total coliforms. The water supplies of the municipalities presented unsafe IRCA. Therefore, it is expected that the results of this study could be used for proposing strategies for improving these conditions by means of the design and implementation of an adequate treatment system.

Published: February 2021

Se trata en esta oportunidad de una respuesta a un proyecto investigativo que reflexiona acerca de la prueba del dolo y culpa grave de los interventores contractuales en procesos de responsabilidad fiscal, a partir de la revisión analítica de decisiones emanadas de la Contraloría General de la República –Gerencia Bolívar–, en el período de gerencia 2012-2018, su objetivo general fue analizar la forma como se ha aplicado a los interventores contractuales, el sistema probatorio subjetivo, en los procesos de responsabilidad fiscal adelantados por esta institución. Para tales fines se desarrolló una investigación jurídica, de enfoque cualitativo y tipo documental, haciendo uso del método hermenéutico. En consonancia con ello, la técnica predominante fue el análisis documental y la triangulación hermenéutica de los resultados. Se presenta así una exposición de casos legales, que constituyen una muestra de procesos de esta entidad que habiendo iniciado bajo la Ley 1474 de 2011, fueron fallados antes de culminar el segundo semestre de 2018, en todos ellos se vinculó al interventor como presunto responsable fiscal.

Introduction Osteoarthritis (OA) is a heterogenic group of disorders of different etiology with similar biological, morphological and clinical manifestations and outcomes. OA is now considered a disease of the whole joint, including alterations in the articular cartilage, subchondral bone, synovial membrane, ligaments, capsule and periarticular muscles. OA of the knee as the most commonly affected joint accounts for the great medical, medical, social and economic impact. Material and methods A literature review assessing Russian and foreign studies on molecular mechanisms of etiology and pathogenesis of knee OA identified a set of factors for which there was consistent evidence for their association with onset of knee OA. A search of studies published in Russian and in English for the last ten years was conducted using bibliographic databases, including PubMed, PubMedCentral, GoogleScholar, eLIBRARY. Search terms included 'knee osteoarthritis', 'etiology', 'pathogenesis', 'risk factors'. Results Review of the literature showed that patients with knee OA are characterized by changes in cartilage, subchondral bone, synovium, suggesting common mechanisms of joint degeneration during OA development. Osteoarthritis (OA) is multifactorial in origin and closely associated with a wide spectrum of local (previous injury, muscle weakness, knee malalignment, knee surgeries, abnormal mechanical loading, excessive high impact sports, occupational physical activities) and systemic risk factors (advanced age, female sex, height, greater body mass index and obesity, hormone status, family history, mineral bone density, vitamin D deficiency, ethnicity). The prevalence of the knee OA and patterns of joint involvement vary among different racial and ethnic groups. Conclusion The literature review allowed us to identify the molecular mechanisms of etiopathogenesis of knee OA and the major risk factors for the pathology.

Introduction Although surgical treatment of carpal tunnel syndrome (CTS) is known to be highly effective outcomes may not be equally satisfactory for the patients due to severity of clinical presentation and objectifying assessment of the condition. Purpose Provide clinical evaluation of outcomes of surgical treatment of CTS using questionnaires and electroneuromyography (ENMG) findings depending on baseline severity of the condition. Material and methods The review included 161 patients who underwent 189 operations of open decompression of the median nerve using mini-access. The patients were assigned to three groups with mild (Group I), moderate (Group II) and severe (Group III) CTS. Evaluations were produced at 6 weeks, 3, 6 and 12 months following the surgery. Results The majority of patients showed positive dynamics, and delayed recovery of the wrist function was noted in Group III at a 12-month follow-up. Patients of Group III exhibited spasmodic improvement of the wrist function at 6-week-to-3-month follow-up. Conclusion Open decompression of the median nerve performed for patients with CTS using mini-approach facilitated substantial clinical and functional improvement in most cases. However, the most favorable results could be provided for mild and moderate CTS.

Purpose Evaluate clinical effectiveness of anatomical reconstruction of the anterior cruciate ligament (ACL) and determine the perspectives for practical health care. Material and methods The review included 706 patients who underwent arthroscopic reconstruction of the ACL and graft interference screw fixation between 2010 and 2018. ACL reconstruction was performed using either anteromedial portal (n = 396, Group I) or an isometric transtibial tunnel technique (n = 310, Group II). Outcomes were evaluated clinically and radiographically using the 2000 International Knee Documentation Committee (2000 IKDC) Subjective Knee Evaluation Form, the Knee Injury and Osteoarthritis Outcome Score (KOOS) and the Tegner Lysholm scoring scale. Clinical and economic outcome measures included surgical time, rehabilitation and disability periods and period of recovery for sports performance. Results The knee anterior drawer test was equally negative and showed no significant differences in the groups. The Lachman test and the pivot shift test showed better results in Group I (p < 0.001). Contractures, atrophic femoral muscles (p < 0.05), synovitis (p < 0.01), vertical position of the femoral graft channels and pathologically extended bone channels with wind-wiper effect (p < 0.001) were more common among patients of Group II. Although knee function returned to normal, as rated with the 2000 IKDC Subjective Knee Evaluation Form, in 91.3 % of cases pathological changes in the knee (C) and severely impaired function (D) were 2.5 and 5 times less common in group I than in Group II (p < 0.05). Pain, symptoms and sport scores were significantly higher on the KOSS scale for Group I (p < 0.05). Surgical time was longer in patients of Group I (p < 0.05) who had shorter rehabilitation period (p < 0.05). Conclusion Anatomical reconstruction of ACL using anteromedial portal was shown to be a more reliable technique as compared to transtibial approach to ensure overall knee stability arranging adequate bone channels. The technique is capable to protect the graft from injury, reduce the likelihood of pain, synovitis, contractures, muscle atrophy, providing shorter rehabilitation, disability period and recovery for sport performance.
