The Exchange of Gifts between Christians and Muslims on Lusignan and Venetian Cyprus 1192–1517
Authors: Coureas Nicholas
Published: September 2023

In this paper which comes under the theme of macro-historical perspectives and Mediterranean history I shall discuss the exchange of gifts in three sections: first between the Lusignan kings of Cyprus and the sultans of Mamluk Egypt and Syria, between the Lusignan kings and the Turkish emirs of Anatolia, and thirdly between the Venetian rulers of Cyprus, including Queen Catherine Cornaro, and the Mamluk sultans for the period postdating 1473. Many of these exchanges of gifts took place during times of war, sometimes during the prelude to hostilities and sometimes immediately after their end. In addition, exchanges of gifts between Christian and Muslim rulers occasionally took place at times of peace. The reasons why gifts were exchanged, the type of gifts exchanged when these are described, not an invariable occurrence, and the symbolism underlying these exchanges of gifts will also be analyzed where possible. Furthermore, occasions when the recipient refused to accept the gift and why it was rejected shall also be examined. Where possible, comparisons with the exchange of gifts taking place in other societies and countries of the Eastern Mediterranean will be alluded to and discussed. In terms of source materials, the Cypriot chronicles of the fifteenth and early sixteenth centuries will form the principal source but reference shall also be made to diplomatic correspondence of the period under discussion. The exchanges of gifts normally took place within a diplomatic setting, this being the arrival of embassies, and gifts were sent sometimes to the close advisers of a ruler who could influence his policy and decision-making. On certain occasions, however, the exchanges of gifts could take place outside of this diplomatic context, for example as an expression of gratitude for assistance received.

Authors: Wang Guangxing , Zhu Yue , An Qing , Wang Huizhen , Su Xing
Published: September 2023

Differential code bias (DCB) of satellite is an error that cannot be ignored in precise positioning, timing, ionospheric modeling, satellite clock correction, and ambiguity resolution. The completion of the third generation of BeiDou Navigation Satellite System (BDS-3) has extended DCB to multichannel code bias observations and observable-specific signal bias (OSB). In this paper, the DCB and OSB products provided by the Chinese Academy of Sciences (CAS) are analyzed and compared. The DCB parameters for the BDS satellites are applied in both single- and dual-frequency single point positioning (SPP), and the results are intensively investigated. Based on the satellite DCB parameters of the BDS, the performance of precise point positioning (PPP) with different frequency combinations is also analyzed in terms of positioning accuracy and convergence time. The standard deviations (STDs) of DCBs at each signal pair fluctuate from 0.2 ns to 1.5 ns. The DCBs of BDS-2 are slightly more stable than those of BDS-3. The mean values and STDs of C2I and C7I OSBs for BDS-2 are at the same level and are numerically smaller than their counterparts for the C6I OSBs. The mean OSBs for each signal of the BDS-3, excluding C2I, fluctuate between 12.35 ns and 12.94 ns, and the STD fluctuates between 2.11 ns and 3.10 ns. The DCBs and OSBs of the BDS-3 of the IGSO satellites are more stable than those of the MEO satellites. The corrections for TGD and DCB are able to improve the accuracy of single-frequency SPP by 44.09% and 44.07%, respectively, and improve the accuracy of dual-frequency SPP by 6.44% and 12.85%, respectively. The most significant improvements from DCB correction are seen in single-frequency positioning with B1I and dual-frequency positioning with B2a+B3I. DCB correction can improve the horizontal and three-dimensional positioning accuracy of the dual-frequency PPP of different ionosphere-free combinations by 13.53% and 13.84% on average, respectively, although the convergence is slowed.

Authors: Hou Zhengyu , Wang Jingqiang , Li Guanbao
Published: September 2023

The acoustic properties of seafloor sediments have always been important parameters in sound field analyses and exploration for marine resources, and the accurate acquisition of the acoustic properties of sediments is one of the difficulties in the study of underwater acoustics. In this study, sediment cores were taken from the northern South China Sea, and the acoustic properties were analyzed. Since traditional methods (such as regression equations or theoretical models) are difficult to apply in practical engineering applications, we applied remote sensing data to sound velocity prediction models for the first time. Based on the influencing mechanism of the acoustic properties of seafloor sediments, the sediments’ source, type and physical properties have a great influence on the acoustic properties. Therefore, we replaced these influencing factors with easily accessible data and remote sensing data, such as parameters of granularity, distance to the nearest coast, decadal average sea surface productivity, water depth, etc., using deep neural networks (DNN) to develop a sound velocity prediction model. Compared with traditional mathematical analyses, the DNN model improved the accuracy of prediction and can be applied to practical engineering applications.

Authors: Qiao Hou , Lin Zhen , Sun Xiangtao , Li Wei , Zhao Yangping , Guo Chuanrui
Published: September 2023

Concrete is the most commonly used construction material nowadays. With emerging cutting-edge technologies such as nanomaterials (graphene, carbon nanotubes, etc.), advanced sensing (fiber optics, computer tomography, etc.), and artificial intelligence, concrete can now achieve self-sensing, self-healing, and ultrahigh performance. The concept and functions of smart concrete have thus been partially realized. However, due to the wider application location (coastal areas, cold regions, offshore, and deep ocean scenarios) and changing climate (temperature increase, more CO2 emissions, higher moisture, etc.), durability monitoring (pH, ion penetration, carbonation, corrosion, etc.) becomes an essential component for smart concrete. Fiber optic sensors (FOS) have been widely explored in recent years for concrete durability monitoring due to their advantages of high sensitivity, immunity to harsh environments, small size, and superior sensitivity. The purpose of this review is to summarize FOS development and its application in concrete durability monitoring in recent years. The objectives of this study are to (1) introduce the working principle of FOS, including fiber Bragg grating (FBG), long-period fiber grating (LPFG), surface plasmon resonance (SPR), fluorescence-based sensors, and distributed fiber optic sensors (DFOS); (2) compare the sensitivity, resolution, and application scenarios of each sensor; and (3) discuss the advantages and disadvantages of FOS in concrete durability monitoring. This review is expected to promote technical development and provide potential research paths in the future for FOS in durability monitoring in smart concrete.

Published: September 2023

Entrectinib is an oral selective inhibitor of the neurotrophic T receptor kinase (NTRK). It is used in the treatment of solid tumors in NTRK gene fusion lung cancer. The study aimed to develop and validate an analytical method for quantifying entrectinib plasma by UPLC-MS/MS using quizartinib as an internal standard. The method involves liquid–liquid extraction of entrectinib from plasma using tert butyl methyl ether. The mass-to-charge transitions were 561.23 → 435.1 for entrectinib and 561.19 → 114.1 for quizartinib. The method was successfully validated according to ICH and FDA guidelines. The method has a low quantification limit of 0.5 ng/mL, and the calibration curves constructed over a wide range of 0.5–1000 ng/mL showed good linearity (≥0.997). This method exhibits a tenfold increase in sensitivity compared with the previous method. The method is also accurate, precise, and reproducible, as evidenced by the inter-day and intra-day accuracy and precision values of 82.24–93.33% and 3.64–14.78%, respectively. Principles of green analytical chemistry were considered during all analytical steps to ensure safety. The greenness of the methods was evaluated using two assessment tools. These tools are the Analytical Eco-Scale and the analytical greenness metric approach (AGREE). The results were satisfactory and compatible with the criteria of these tools for green assessment. This method is green, accurate, precise, and reproducible. The method can be used to quantitate entrectinib in plasma and its pharmacokinetics in preclinical, and therapeutic drug monitoring.

Published: September 2023

The release of 1,4-dioxane probably contributes to the deterioration of marine habitats, animal health, and human liver and kidneys. The formulation of 1,4-dioxane in glycols, which has been applied for dehumidifying agents in refineries, may need to be replaced to ensure public health. Further, it is necessary to identify and precisely determine the levels of 1,4-dioxane in glycols for food quality control and environmental safety regulation. The objectives of this study were to validate a liquid–liquid extraction (LLE) method for 1,4-dioxane analysis and to optimize the LLE conditions using a response surface methodology (RSM). With consideration of the food matrix and its applications, polyethylene glycol 200 was used as the model system and analyzed by gas chromatography with flame ionization detection. In the experiments for the optimum extraction temperature and time of 1,4-dioxane in ultrasonic treatment, they were 20 °C and 10 min, respectively. The experimental conditions and results were analyzed by RSM with the Box–Behnken design, and the optimal extraction conditions for the LLE were determined to be coded with three independent variables (sample weight, solvent volume, and centrifugation speed). The amount of 1,4-dioxane increased as the amount of sample increased, whereas the amount of 1,4-dioxane decreased as the amount of solvent increased. This information can help to find the analytical methods for regulating the 1,4-dioxane content and its precise quantification in food products.

Published: September 2023

In order to ensure the successful construction and stable operation of deep engineering projects, significant progress has been made in researching deep underground rockburst issues from various perspectives. However, there have been few systematic analyses of the overall research status of deep rockburst to date. In this study, a bibliometric approach using CiteSpace software (version 6.2.R3) was employed to visualize and analyze knowledge maps of 353 research articles on deep rockburst collected from the Web of Science core database from 1996 to 2022. The results show that the number of publications experienced exponential growth after an initial stage of budding and peaked in 2016. In terms of collaboration, China plays an absolute central role. The top three highly cited journals were the International Journal of Rock Mechanics and Mining Sciences, Rock Mechanics and Rock Engineering, and Tunneling and Underground Space Technology. In the keyword co-occurrence analysis, the keyword “prediction” had the highest frequency of occurrence in the past two decades, indicating it as the major research focus in deep rockburst studies. The keyword co-occurrence clustering analysis revealed eight clusters, including conventional criteria, acoustic emission, geology, seismic velocity tomography, dynamic disturbance, and others, representing the primary research topics. This study provides a comprehensive analysis of the current research progress and development trends of deep underground rockburst, helping to understand the key areas of focus in this field and providing potential prospects for future investigations for researchers and practitioners.
Developing Platform Supply Chain Contract Coordination and a Numerical Analysis Considering Fresh-Keeping Services
Authors: Wang Yong , Deng Xudong , Lu Qian , Guan Mingke , Lu Fen , Wu Xiaochang
Published: September 2023

With changes in demand and the emergence of new distribution channels, consumer-centric buyer’s markets for many products have been formed. The platform supply chain has been continuously optimized and upgraded. Supply chain leaders have moved downstream to the end of the supply chain. The operational value has been further enhanced. The corresponding systematic construction of the platform supply chain has become an important driving force for future development. The model in this paper is different from the traditional supply chain contract model, which mainly focuses on suppliers or demand. In order to meet the requirements of fresh-keeping services and the goal of revenue sharing, we integrate the production and circulation characteristics of fresh produce into the design of a contract model. In this paper, a revenue-sharing contract model of the fresh produce supply chain is constructed based on the core position of retailers, the uncertainty of the market size, and the consideration of a fresh-keeping service. The model is mainly composed of the core retailer and the supplier. Through further numerical analysis, we verify the effectiveness of the revenue-sharing contract model in supply chain coordination. We also analyze the change trends in the optimal retail price, optimal freshness level, and optimal order quantity caused by changes in both the fresh-keeping service capacity and the revenue-sharing coefficient. The results show that after changing these two parameters, the supply chain can achieve coordination under the specified parameter values. The changed parameters will also lead to certain change trends in the optimal retail price, optimal freshness level, and optimal order quantity, and will have a corresponding impact on the stability of supply chain operation. This research provides a relevant theoretical and empirical basis for a fresh produce supply chain contract model with retailers at the core position. We also provide guidance and reference for optimizing the supply chain management mode and improving the overall operational efficiency of the fresh produce supply chain.
Exploring Urban Flood Policy Trends Using a Socio-Hydrological Approach—Case Studies from Japanese Cities
Authors: Hong Chang-Yu , Tanaka Kiyoyasu
Published: September 2023

Most industrialized nations have attempted to control floods through civil engineering technologies. However, these measures have failed in the face of immense natural forces. Through allomorph analysis and expert interviews, this study examined the situation of implementing urban flood rules in major Japanese cities. The river canal in the Tokyo region is mostly maintained through infrastructure, and Tokyo has a diverse network of systems linked by rivers, canals, and drainage channels, which demonstrates its dominance in structural and civil engineering flood management. In Osaka Prefecture, flood risk management is an ongoing process built on a structural engineering foundation, and local governments continue to examine and update new policies to handle the risks and difficulties produced by ever-changing flood catastrophes. To enhance public education and awareness, local administrations in the Toyama and Chiba Prefectures are implementing programs to educate locals about flood hazards and preparation. To summarize, public engagement is an important component of flood risk mitigation and management in Japanese communities. Governments may help communities become more resilient and prepared in the face of floods by involving local residents, institutionalizing public education and awareness, and building volunteer networks. This is the conclusion reached as a result of socio-hydrological intervention.
School Space and Sustainability in the Tropics: The Case of Thermal Comfort in Brazil
Authors: Rocha Ana Angelita Costa Neves da , Nachez Juan Lucas
Published: September 2023

This work aims to discuss thermal comfort and school architecture in Brazil, within the Anthropocene framework. The objective traverses the fields of school management, curriculum, and educational policy. The importance of the environmental emergency in the context of the Anthropocene is recognized, understanding it as a space-time in which climate change biopolitically impacts both local and global daily life. In this way, we consider that the curricular dimension together with school architecture, in the Anthropocene scenario, tends to respond to the demands of biosecurity. The methodology of this article is the analysis of documentary sources, particularly current Brazilian legislation on school architecture, thermal comfort, and public funding. The initial hypothesis of this work operates with the argument that in Brazilian legislation there is a predominance of HVAC (Heating, Ventilating and Air Conditioning) systems over sustainable forms such as natural ventilation, design of classrooms, placement of windows, use of trees and vegetation and management of the student’s schedule. The assumption of the research lies in the need for reconfigurations of the principles of school architecture, considering both biosecurity and bioclimatic architecture essential for the future in the scenario of climate extremes along the Anthropocene.

Published: September 2023

Biodiesel is a promising sector worldwide and is experiencing significant and rapid growth. Several studies have been undertaken to utilize homogeneous base catalysts in the form of KOH to develop biodiesel in order to establish a commercially viable and sustainable biodiesel industry. This research centers around extracting potassium hydroxide (KOH) from banana trunks and employing it in the transesterification reaction to generate biodiesel from waste cooking oil (WCO). Various operational factors were analyzed for their relative impact on biodiesel output, and after optimizing the reaction parameters, a conversion rate of 95.33% was achieved while maintaining a reaction period of 2.5 h, a methanol-to-oil molar ratio of 15:1, and a catalyst quantity of 5 wt%. Response surface methodology (RSM) and artificial neural network (ANN) models were implemented to improve and optimize these reaction parameters for the purpose of obtaining the maximum biodiesel output. Consequently, remarkably higher yields of 95.33% and 95.53% were achieved by RSM and ANN, respectively, with a quite little margin of error of 0.0003%. This study showcases immense promise for the large-scale commercial production of biodiesel.
The Problem of Moments: A Bunch of Classical Results with Some Novelties
Authors: Novi Inverardi Pier Luigi , Tagliani Aldo , Stoyanov Jordan M.
Published: September 2023

We summarize significant classical results on (in)determinacy of measures in terms of their finite positive integer order moments. Well known is the role of the smallest eigenvalues of Hankel matrices, starting from Hamburger’s results a century ago and ending with the great progress made only in recent times by C. Berg and collaborators. We describe here known results containing necessary and sufficient conditions for moment (in)determinacy in both Hamburger and Stieltjes moment problems. In our exposition, we follow an approach different from that commonly used. There are novelties well complementing the existing theory. Among them are: (a) to emphasize on the geometric interpretation of the indeterminacy conditions; (b) to exploit fine properties of the eigenvalues of perturbed symmetric matrices allowing to derive new lower bounds for the smallest eigenvalues of Hankel matrices (these bounds are used for concluding indeterminacy); (c) to provide new arguments to confirm classical results; (d) to give new numerical illustrations involving commonly used probability distributions.
Orbivirus NS4 Proteins Play Multiple Roles to Dampen Cellular Responses
Authors: Mohd Jaafar Fauziah , Belhouchet Mourad , Monsion Baptiste , Bell-Sakyi Lesley , Mertens Peter P. C. , Attoui Houssam
Published: September 2023

Non-structural protein 4 (NS4) of insect-borne and tick-borne orbiviruses is encoded by genome segment 9, from a secondary open reading frame. Though a protein dispensable for bluetongue virus (BTV) replication, it has been shown to counter the interferon response in cells infected with BTV or African horse sickness virus. We further explored the functional role(s) of NS4 proteins of BTV and the tick-borne Great Island virus (GIV). We show that NS4 of BTV or GIV helps an E3L deletion mutant of vaccinia virus to replicate efficiently in interferon-treated cells, further confirming the role of NS4 as an interferon antagonist. Our results indicate that ectopically expressed NS4 of BTV localised with caspase 3 within the nucleus and was found in a protein complex with active caspase 3 in a pull-down assay. Previous studies have shown that pro-apoptotic caspases (including caspase 3) suppress type I interferon response by cleaving mediators involved in interferon signalling. Our data suggest that orbivirus NS4 plays a role in modulating the apoptotic process and/or regulating the interferon response in mammalian cells, thus acting as a virulence factor in pathogenesis.

Published: September 2023

As a crucial surface water resource, the Yangtze River has raised concerns about its water quality due to its importance in economic and social development, environmental conservation, and agricultural development. The principal component analysis (PCA), hierarchical clustering analysis (HCA), and the water quality index (WQI) were utilized to assess the overall condition and detect spatiotemporal patterns and the key parameters of water quality in the Yangtze River. All usage data were determined monthly from samples taken in 2021 at the 33 Yangtze River water quality monitoring stations. The results demonstrated that 85% of the monitoring stations in the whole Yangtze River were maintained at a “good” condition, with average WQI values ranging from 71.16 to 81.25. The water quality was slightly poorer in the summer, with 56.6% of monitoring stations being in “medium” condition. Spatially, there was a downward trend in the water quality from upstream to downstream. Two significant principal component scores (PCs) were produced as a result of PCA and HCA, explaining 60.3% of the total variance in the upstream, 67.4% in the transition zone, and 50.4% in the downstream, respectively. In addition, the middle–upper reaches of water quality were found to correlated with CODMn, whereas the water quality in the downstream were mainly influenced by TUR, TP, T, and DO. The results primarily motivated our understanding of the Yangtze River’s water quality status and suggested the main targets for water quality improvement in different monitoring areas.

Published: September 2023

Os Estudos de Impacto de Vizinhança (EIV) de projetos de recuperação e alteração na infraestrutura da rodovia BR - 319/AM/RO, são de suma importância como ferramentas de apoio ao planejamento à gestão do projeto no sentido de atenuar os possíveis impactos adversos em torno da rodovia, tanto na fase de implantação quanto em sua fase de operação e/ou execução. Embora estes estudos de EIV tenham por objetivo identificar previamente os impactos significativos na área de influência do empreendimento, com vistas à elaboração de um diagnóstico ambiental e socioeconômico, eles não respondem se o projeto é sustentável ou não, ou seja, se existe um equilíbrio entre os impactos sociais, ambientais e econômicos gerados pela implantação e execução do projeto. Dessa forma, criou-se neste estudo, um Índice de Sustentabilidade para Projetos de Infraestrutura Rodoviária (ISPIR). O ISPIR é baseado no método Analytic Hierarchy Process (AHP) que utiliza técnicas matemáticas de álgebra linear para determinar a importância dos aspectos Sociais, Ambientais e Econômicos durante as fases de implantação e execução do empreendimento. O índice proposto foi aplicado ao projeto de execução da obra de construção da ponte sobre o Rio Madeira localizada na rodovia BR-319/AM/RO e verificou-se que o projeto é mediano sustentável.

Published: September 2023

Given the situation of poverty and marginalization in which most of the communities in the rural areas of the Mexican South Southeast are found, a situation that affects 17 million people classified as in a situation of extreme poverty, agribusiness is an alternative under these conditions for it. An operational and practical methodology is required that allows a good identification and implementation of initiatives according to the situation and the environment. The objective of this work was to validate an operational methodological model called model for the competitiveness of small farmers in extreme poverty based on agribusiness. The validation project was developed in four pilot communities in the Mexican South Southeast considered to be highly marginalized and poor: San Andrés Tuxtla, Veracruz; Tahdziu, Yucatan; Ocotepec, Chiapas and San Jerónimo Taviche, Oaxaca. The applied model consists of four stages, diagnosis, incubation, development and maturity. The diagnosis considered in turn two sub-stages, one on the description of the environment and the actors and the second on the definition of the portfolio of opportunities. The incubation considered the sub-stages of prioritization through a qualification criteria and the business plan itself according to the conditions of the actors and the environment. The development stage is nothing more than the start-up and consolidation of the business with a view to continuous improvement. The results obtained were four agribusinesses in progress, one for each pilot community, with profitability indicators such as the Internal Rate of Return (IRR) of 35.0%, 100.0%, 41.0% and 45.9% for jam production in San Andrés Tuxtla Veracruz, Stevia production and marketing in Tadhziu Yucatán, Hass avocado production and marketing in San Pablo Huacanó Chiapas and tomato production and marketing in greenhouses in San Jerónimo Taviche Oaxaca, respectively. The operational methodological model to identify and develop agribusiness in poor and marginalized communities was successfully validated. It is concluded that it is possible to develop profitable and competitive agribusiness in conditions of extreme poverty and marginalization.

Published: September 2023

A cultura de que pessoas devem ser subservientes a outras, deve-se a condição histórica da escravidão no Brasil durante a Colonização Portuguesa. Com o intuito de externar essa problemática, o texto abordará realidades vivenciadas por pessoas negras e suas consequências a fim de propor soluções dentro do ordenamento jurídico brasileiro. No mundo contemporâneo, a desigualdade racial ainda mostra-se presente na sociedade, tendo em vista recorrentes situações de constrangimentos e discriminações com pessoas que são vítimas dessa prática ilícita, desumana e desigual. Objetivos: Acompanhar os desafios enfrentados por pessoas negras na sociedade. Descrever casos concretos e práticas rotineiras de cunho discriminatório racial. Levantar ferramentas para minimizar a prática da desigualdade racial. A pesquisa terá como base a Lei n° 12.288/10, Estatuto da Igualdade Racial, garantindo a população negra a igualdade de oportunidades e a defesa dos direitos étnicos de forma efetiva, visando casos concretos. Dados apontam expressamente as dificuldades de pessoas negras serem inseridas na sociedade, principalmente no âmbito educacional e socioeconômico. Em um caso ocorrido no início de 2013, no Rio de Janeiro, um casal relatou que seu filho de 7 anos na época, negro e adotado foi vítima de preconceito racial em uma concessionária da BMW. O menino ficou em um espaço separado assistindo a um desenho, enquanto seus pais foram encaminhados ao gerente de vendas da loja. A discriminação aconteceu quando um gerente da loja se dirigiu a ele dizendo que não poderia ficar no local e que ali não era lugar para ele. Em nenhum momento cogitaram a possibilidade da criança ser filha do casal, sendo que essa conduta não ocorreria se fosse uma criança branca. O artigo 3º, IV da CRFB/88 e o art. 1º, inciso I, do Estatuto da Igualdade Racial, apontam de forma evidente que ações como a narrada anteriormente são descritas como conduta ilegal, sendo premente a necessidade de maior conhecimento do contexto normativo do Estatuto, através de políticas públicas pedagógicas que devem ser iniciadas no sistema educacional, bem como a promoção de campanhas intensivas com o foco na redução de preconceitos e melhor inclusão dos negros na sociedade. Desta forma, conclui-se que é necessário o reconhecimento da desigualdade racial como um problema estrutural e, diante disso, faz-se necessário adotar uma postura institucional antirracista.

A compreensão do atraso no desenvolvimento neuronal é vital para garantir o bem-estar e o futuro de crianças em todo o mundo. O desenvolvimento neuronal é um processo complexo que molda a capacidade cognitiva, emocional e social das crianças desde tenra idade. No entanto, quando esse desenvolvimento sofre atrasos, surgem desafios significativos que podem impactar a vida das crianças e suas famílias. Esta introdução visa explorar os diversos aspectos relacionados ao atraso no desenvolvimento neuronal, incluindo sua definição e classificação, métodos de avaliação e diagnóstico, intervenção precoce, opções de tratamento e os desafios futuros que esse campo enfrenta. Ao abordar essas áreas, busca-se não apenas ampliar o conhecimento sobre o tema, mas também enfatizar a importância de identificar e tratar precocemente o atraso no desenvolvimento neuronal para permitir que cada criança alcance seu potencial máximo e desfrute de uma qualidade de vida plena e significativa.
A Obra Clássica “Grondmechanica” de Keverling Buisman (1940) revisitada: tradução e comentários sobre a sua importância no desenvolvimento da moderna teoria da capacidade de carga de fundações superficiais

A moderna Teoria da Capacidade de Carga de Fundações Superficiais teve seu estudo inicial no trabalho de 1920 do professor alemão Ludwig Prandtl, intitulado “Über die Härte plastischer körper” (“sobre a Dureza dos Corpos Plásticos”), objetivando determinar os estados de tensão e deformação em materiais de comportamento plástico, ante a penetração de um corpo rígido, em um ensaio de indentação de metais. Esse estudo não levara em consideração o peso próprio do material nem sobrecarga na sua superfície. Posteriormente, o professor alemão Hans J. Reissner publicara, em 1924, o trabalho denominado “Zum Erddruckproblem” (“O Problema da Pressão de Terra”), em que aborda, entre outras relevantes questões de empuxos de terra, a questão da influência de sobrecargas vertical e inclinada localizadas na superfície do terreno na plastificação de uma fundação superficial. Posteriormente, houvera a contribuição do professor holandês A.S. Keverling Buisman (1940), estendendo as duas soluções anteriores de capacidade de carga para o caso do peso da massa de solo. Em seguida, outros autores continuaram o desenvolvimento dos estudos, até se chegar ao clássico trabalho desenvolvido por Terzaghi, em 1943. Portanto, justifica-se a apresentação de uma versão rigorosa de parte do Capítulo VIII intitulado “Draagvermogen van een Fundeeringsgrondslag” (“Capacidade de Carga de uma Base de Fundação”), do livro “Grondmechanica” (“Mecânica dos Solos”), de autoria de A.S. Keverling Buisman, publicado em 1940, em Delft, Holanda, esperando-se contribuir para a evolução do conhecimento científico no dimensionamento geotécnico de fundações rasas. No final deste artigo, este presente autor elaborou uma tabela “ângulo de atrito do solo f versus Vg”, a partir do gráfico da Figura 15, e, com esse par de valores, empregou o programa computacional LabFit®, para determinação da equação com melhor regressão não linear, entre as variáveis independentes, para encontrar o que seria o fator de capacidade de carga Vg (ou Ng) de Keverling Buisman (1940). A equação encontrada com melhor combinação foi .

Introdução. Um estudo de um colégio Brasileiro em 2012 pode prever um aumento significativo em relação aos números de casos de câncer no Brasil. Este aumento passou de números que rondavam cerca de 14 milhões de casos para 19 milhões de casos, isso no período de mais ou menos 10 anos. Um fator importante aqui é que há uma disparidade em relação aos números de casos em relação ao acesso as cirurgias oncológicas. Esse fator é essencial para promover maior chance de vida a todos aqueles que passam por essa doença. Desta forma, este trabalho é uma revisão acerca dos achados e suas manifestações para que no futuro possamos triar, buscar e analisar fatores que possam suavizar, alongar e confortar pacientes com essa mutação gênica. Objetivo. Com este trabalho, buscamos analisar e compreender fatores que possam facilitar a vida dos pacientes com câncer, seja esses fatores psicológicos, sociais e econômicos, afim de facilitar e prolongar seu tempo de vida. Metodologia. A estratégia utilizada contou com estudos, tendo por base uma análise em plataformas como o Google Acadêmico, PubMed, SciELO, Medical Subject Heading (MeSH), nas quais cada fonte de dados contou com um estudo acerca dos títulos, assuntos e tipos específicos na língua portuguesa e inglesa. Resultados. Fatores encontrados como, baixa demanda em relação a profissionais adequados, baixos investimentos na rede pública, nos mostram que adequações devem ser realizadas, afim de apropriar todas as redes de saúde, públicas ou particulares, afim de evitar o sofrimento de pessoas que estão em um estado emocional já afetado. Conclusão. Este estudo oferece uma visão distinta em relação a forma de pensar e analisar as alterações gênicas causadas acerca dos fatores oncológicos após procedimento cirúrgico. Contudo, também fica claro que a vigilância nestes pacientes se faz necessária, afim de garantir uma qualidade de vida melhor após a retirada de tumores, como no caso do câncer de mama.
