Published: May 2020

Os Emirados Árabes Unidos passaram as últimas duas décadas trabalhando para transformar seu litoral, ampliando território e criando paisagens artificias monumentais como as ilhas artificiais, para mudar sua economia baseada no petróleo para uma economia de serviços e turismo. A rápida expansão da cobertura do solo urbano acarretou sérios desafios para a sustentabilidade do País. Este artigo, que tem a Ilha Palm Jumeirah como exemplo tem como objetivo estudar o desenho, a construção das ilhas e sua relação com a sustentabilidade. Para o estudo, partiu-se do reconhecimento prévio da área, pelo autor, a partir de visitas ao local, levantamentos bibliográficos, registros fotográficos e observações. Um estudo de campo foi necessário, devido à falta de pesquisas similares anteriores.

Inland Water Transport and Urban Mobility in Ikorodu-Ebutte Ero Route, Lagos, Nigeria
Authors: Abdulkadir Usman Bolaji , Halimat Animashaun Kikelomo
Published: May 2020

Lagos city has abundant navigable inland waterways which if fully harnessed would help minimise road traffic congestion, pollution and provide low cost means of long distance travel within the city. This study examines inland water transport services on Lagos lagoon focusing on Ikorodu-Ebutte Ero route. Primary data were obtained using structured questionnaires. While, secondary data were sourced from relevant government and private agencies. Data were analysed using descriptive techniques including frequency counts, tables and graphs. The results revealed an inadequate provision of terminal facilities and vessels in the area. It was also found that most (67.3%) of the trips via water transport in the were mainly for work purpose. In addition, low patronage was observed and it was found to be mostly due to comparatively high cost of fares and passenger safety concerns, as indicated by 67.4% and 58.7% of the respondents respectively. Furthermore, high income earners where found to patronise this mode than low income earners. The high frequency of use of water transport by the respondents (71.3% travel by water every day) indicates that, this mode has great potential of being widely adopted, if greater attention is given to its development by both the government and private sector. There is, therefore, a need for more investment in water transportation in the area through the provision of modern infrastructure and vessels.

Keywords: urban mobility; inland waterways; transport services; sustainable transportation; integrated transport.

Factor analysis of competence management practices
Authors: Hedhili Mohamed Ali , Boudabbous Sami
Published: May 2020

The concept of competence has recently been a hot topic in science management, particularly human resource management. However, most of the studies conducted on this topic have mainly been theoretical. Thus, the present study aims to operationalize competence management through the construction and validation of a questionnaire intended for Tunisian project managers. To this end, a quantitative study is conducted among 156 respondents. The principal component analysis and Cronbach's alpha calculations were used to ensure the validity and reliability of the factor structures. The results of the factor analysis confirm the existence of a measurement scale of competence management that comprises five independent dimensions, namely recruitment, assessment, training, compensation, and career management. This study provides project managers with a measurement instrument that can be used to analyze competence management practices in their companies so that they can develop and enhance their employees’ skills.
The Rotor and Tower Vibrations Damping Monitoring in the Case of Total Pitch Servomotors Failure
Authors: Elmaati Younes Ait , El Bahir Lhoussain , Faitah Khalid
Published: May 2020

In this paper, a strategy is proposed to deal with the total pitch actuator failure in the modern wind turbines. The fault is firstly detected using a suitable proportional residual which rises when the measured rotor dynamics match the pure wind turbulence driven dynamics of the reference model. The fault tolerant control method relies on the distribution of the control signal on the remaining actuators, namely the generator torque and the yaw actuator. The pseudo inverse is applied on the residual between the measured and the nominal dynamics of the tower and the rotor. The distributed control signal is then suitably filtered in order to match the production and the safety objectives. Firstly, the generator torque filter comes to minimize the high frequencies on the rotor speed for a stable production to the grid. Secondly, the band pass yaw angle filter comes to minimize the mean yaw misalignment between the yaw nacelle and the wind direction. The method shows good dynamics reconstruction capabilities while keeping a stable production within a safe environment.
Effect of Flow on Various Helmholtz Resonators
Authors: Kim Hyunsu , Lee Iljae
Published: May 2020

The acoustic performance of Helmholtz resonators with different configurations in the presence of mean flow is experimentally investigated. The transmission loss of Helmholtz resonators is measured using a flow-impedance tube setup to identify mean flow effects. First, Helmholtz resonators under two different flow conditions, grazing and direct flow, are considered at Ma=0.05 and 0.1. Then the impact of mean flow on the transmission loss of Helmholtz resonators with leakage holes is also demonstrated. For Helmholtz resonators with leakage holes, single peak of transmission loss is identified at Ma=0.0 and 0.1. However, two peaks appear at Ma=0.05 as the number of opening holes increases. The experimental results show that the effect of mean flow strongly depends on the configurations of Helmholtz resonators and the conditions of mean flow. Thus the variation of acoustic performance due to mean flow should be considered in the design of Helmholtz resonators.
1D Numerical Study of Nonlinear Propagation of Finite Amplitude Waves in Traveling Wave Tubes with Varying Cross Section
Authors: Zhang Zhineng , Zheng Ling , Yan Tingfei , Wu Yao
Published: May 2020

The nonlinear acoustic problem of a finite amplitude plane wave propagating along the axial direction in a traveling wave tube is studied. Based on the one-dimensional Westervelt equation, a one-dimensional nonlinear wave equation is derived in which the cross section of the traveling wave tube is considered. The two-order finite difference scheme is used to solve the nonlinear wave equation. The nonlinear propagation characteristics of a finite amplitude wave in the traveling wave tube is analyzed. In the expanding transition section, the acoustic pressure amplitude of the acoustic wave decreases with the increase of the cross-sectional area of the pipeline. The nonlinear characteristics of the acoustic wave show waveform distortion and harmonic growth. The waveform distortion becomes more serious in the rear of traveling wave tube than in the front of the tube. Considering the acoustic reflection condition at the mouth, the influence of differently shaped diffusion sections on the acoustic pressure distribution in the test section is investigated. The larger the change rate of the diffusion section in an area, the less amplitude of the sound pressure, and the nonlinear effect of the sound wave propagation is weakened. These nonlinear wave propagation characteristics in a travelling wave tube provide important guidance for both designing a uniform sound pressure distribution in the test section and determining the optimal measuring points for different sizes of structures in spacecraft.
Fluid Added-Mass Effect on Flexural Vibration of Hemispherical Shell Structure
Authors: Sepehrirahnama Shahrokh , Wijaya Felix Bob , Oon Darren , Ong Eng Teo , Lee Heow Pueh , Lim Kian-Meng
Published: May 2020

In this hydroelasticity study, the fluid added-mass effect on a hemispherical shell structure under flexural vibration is investigated. The vibration response of the hemisphere is solved by using a commercial finite element software (ABAQUS) coupled with an in-house boundary element code that models the fluid as potential flow. The fluid-structure interaction is solved as a fully-coupled system by modal superposition to reduce the number of degrees of freedom. The need for an iterative scheme to pass displacement/force information between the two solvers is avoided by direct coupling between the fluid and structure equations. The numerical results on the downward shift in natural frequencies due to added-mass effect compare well with vibration measurements conducted on a stainless-steel bowl with interior and exterior fluid. For water and soap-water solution used in the experiments, the fluid viscosity (varying over a wide range) did not have any significant effect on the wet natural frequencies. This is due to the small viscous boundary layer (milimetre scale) compared to the nominal size of the bowl in centimetres. For such cases, the fluid-added mass only depends on the density of the fluid and the use of potential flow in the numerical model is applicable.
Los paisajes de la sal y la música Española = The landscapes of salt and Spanish music
Authors: Núñez Faustino
Published: May 2020

RESUMEN:Si los italianos son dulces, los españoles somos salaos. La sal como analogía de una idiosincrasia que mezcla lo exótico con el desparpajo propio de los hispanos. En contraposición a la delicadeza del europeo el temperamento español. Aunque sea considerado un tópico, en nuestra música queda reflejado a la perfección ese carácter. La música española es extrovertida, abierta, simpática, sociables, cordial, salada. En los géneros inspirados en la música tradicional más que en aquellos cultivos en la música académica se aprecia ese carácter, y entre ellos, y ahí vamos a centrar nuestra exposición, en las tonadillas, sainetes y entremeses de la segunda mitad del siglo XVIII y en nuestro género más internacional, el flamenco. En esta ponencia repasamos aquellos momentos en los que la sal es protagonista y, en la medida de lo posible, expondremos los elementos musicales que podemos considerar salados en los géneros mencionados. Estos contenidos han sido recopilados en los últimos años a través de la investigación en los archivos y bibliotecas que contienen las partituras de estas obras, así como el análisis de los estilos flamencos. ABSTRACT:If the Italians are sweet, the Spaniards are salty (salaos). Salt as an analogy of an idiosyncrasy that mixes the exotic with the self-confidence of Hispanics. In contrast to the delicacy of the European, the Spanish temperament. Although it is considered a topic, in our music that character is perfectly reflected. Spanish music is outgoing, open, friendly, sociable, friendly, salty. In the genres inspired by traditional music more than in those crops in academic music, that character is appreciated, and between them. And there we will focus our exhibition, on the tonadillas, saleros and hors d'oeuvres of the second half of the 18th century and on our most international genre, flamenco. In this paper, we review those moments in which salt is the protagonist and, as far as possible, we will present the musical elements that we can consider salty in the aforementioned genres. These contents have been compiled in recent years through research in the archives and libraries that contain the scores of these works, as well as the analysis of flamenco styles.

RESUMEN:Acercamiento personal a la historia de la arquitectura de la sal, a través del estudio y documentación de ejemplos españoles. Empleamos el término arquitectura definido por William Morris (1881), en una concepción territorial incorporada en las contemporáneas definiciones patrimoniales: Paisaje Cultural (Carta de Cracovia, 2000), como el resultado y reflejo de una interacción prolongada a través de diferentes sociedades entre el hombre, la naturaleza y el medio ambiente físico. Los primeros contactos con salinas mediterráneas, como las de Cabo de Gata, la masiva presencia de fábricas de salazón romanas, como la de Sexi con origen fenicio. Salinas de mar modernas que emplean la amplitud de la marea, como Las Puntas en la isla canaria de El Hierro. Las salinas de interior, con utilización desde el neolítico y de gran importancia desde época medieval, como Poza de la Sal, Imón o Belinchón, vinculadas a trabajos de Inventario del patrimonio arquitectónico y declaraciones de BIC de los años 70 y 80 y otras investigaciones del patrimonio rural español. Su relación con la ganadería y la Mesta, su transporte histórico apoyado en la Cabaña Real de Carreteros, para detenernos en ejemplos de alfolíes y almacenes, presentes en salinas y núcleos de población. ABSTRACT:Personal approach to the history of salt architecture, supported by studies and research of Spanish examples.

Sal y salud. Poblaciones y territorios = Salt and Health. Populations and Territories
Authors: Pozo Menéndez Elisa
Published: May 2020

RESUMEN:El vínculo entre salud humana y medio ambiente ha adquirido en la actualidad una gran relevancia. Ya en la Antigüedad, las primeras civilizaciones estudiaban los condicionantes del entorno natural para elección de los asentamientos y ciudades. Este conocimiento tradicional se ha ido perdiendo y, muestra de ello, son las enfermedades y epidemias consecuencia de asentamientos inadecuados. En este contexto, la sal se ha utilizado a lo largo de los siglos para usos muy diversos. A medida que la medicina y las investigaciones han ido evolucionando, la sal ha adquirido igualmente una gran visibilidad en cuanto a su relación con la salud. Los hábitos de vida y consumo en la actualidad están perjudicando negativamente no solo a la salud humana, sino a la salubridad medioambiental. La puesta en valor del patrimonio, el paisaje cultural y la artesanía conecta a las personas con los territorios de una forma todavía poco explorada y que requiere mayor investigación. Este trabajo muestra la necesidad de seguir fomentando los estudios interdisciplinares y la colaboración entre distintas áreas de conocimiento, para poder comprender mejor las relaciones causa-efecto entre el medio ambiente, los territorios, hábitos y estilo de vida y la salud humana. ABSTRACT:The connection between human health and environment has recently acquired special relevance. Since antique times, first civilizations already studied environmental conditionants in order to chose the optimal place for settlements and cities. This traditional knowledge has been gradually lost and proof of that are the diseases and epidemies consequence of innacurated settlements. In this context, salt has been used during centuries with different applications. As long as medicine and scientific research have evolved, the salt and its relationship with health have become more visible. Modern lifestyles and consumption patterns are affecting negatively both human health and environmental healthiness. Emphasizing the heritage, cultural landscapes and artisan activities make people develop special connections with territories that need to be explored yet. This paper shows the interest on supporting interdisciplinary studies and collaboration between different fields, in order to better understand the relations cause-effect between environment, territories, habits and lifestyles and human health.

Background:

The aim of our study was to explore the impact of elective-surgery deferment on the United States health-care system and subsequent recovery after COVID-19 containment. Using an orthopaedic elective surgery model, we aimed to answer the following: (1) What is the expected recovery time until the health-care system is back to nearly full capacity for performing elective surgery? (2) What will be the expected backlog of elective surgery over time? (3) How should health care change to address the backlog?

Methods:

A Monte Carlo stochastic simulation-based analysis was performed to forecast the post-pandemic volume of elective, inpatient total joint arthroplasty and spinal fusion surgical cases. The cumulative backlog was calculated and analyzed. We tested model assumptions with sensitivity analyses.

Results:

Assuming that elective orthopaedic surgery resumes in June 2020, it will take 7, 12, and 16 months—in optimistic, ambivalent, and pessimistic scenarios, respectively—until the health-care system can perform 90% of the expected pre-pandemic forecasted volume of surgery. In the optimistic scenario, there will be a cumulative backlog of >1 million surgical cases at 2 years after the end of elective-surgery deferment.

Conclusions:

The deferment of elective surgical cases during the SARS-CoV-2 pandemic will have a lasting impact on the United States health-care system. As part of disaster mitigation, it is critical to start planning for recovery now.

Background: The Majority (99%) of maternal deaths occur in low and middle-income countries. The three most important causes of maternal deaths in these regions are postpartum hemorrhage, pre-eclampsia and puerperal sepsis. There are several diagnostic criteria used to identify sepsis and one of the commonly used criteria is systematic inflammatory response syndrome (SIRS). However, these criteria require laboratory investigations that may not be feasible in resource-constrained settings. Therefore, this study aimed to develop a model based on risk factors and clinical signs and symptoms that can identify sepsis early among postpartum women. Methods: A case-control study was nested in an ongoing cohort of 4000 postpartum women who delivered or were admitted to the study hospital. According to standard criteria of SIRS, 100 women with sepsis (cases) and 498 women without sepsis (controls) were recruited from January to July 2017. Information related to the socio-demographic status, antenatal care and use of tobacco were obtained via interview while pregnancy and delivery related information, comorbid and clinical sign and symptoms were retrieved from the ongoing cohort. Multivariable logistic regression was performed and discriminative performance of the model was assessed using area under the curve (AUC) of the receiver operating characteristic (ROC). Results: Multivariable analysis revealed that 1-4 antenatal visits (95% CI 0.01 - 0.62) , 3 or more vaginal examinations (95% CI 1.21 - 3.65), home delivery (95% CI 1.72-50.02), preterm delivery, diabetes in pregnancy (95% CI 1.93-20.23), lower abdominal pain (95% CI 1.15 - 3.42)) vaginal discharge (95% CI 2.97-20.21), SpO2 <93% (95% CI 4.80-37.10) and blood glucose were significantly associated with sepsis. AUC was 0.84 (95% C.I 0.80-0.89) which indicated that risk factors and clinical sign and symptoms-based model has adequate ability to discriminate women with and without sepsis. Conclusion: This study developed a non-invasive tool that can identify postpartum women with sepsis as accurately as SIRS criteria with good discriminative ability. Once validated, this tool has the potential to be scaled up for community use by frontline health care workers.
Establishment of Kidney Cancer Organoid Cultures
Authors: Bauer Daniel , Birchmeier Walter , Fendler Annika
Published: May 2020

This protocol describes an efficient novel method for cultivating kidney cancer organoids, derived directly from human clear cell renal cell carcinomas (ccRCC) or sorted cancer stem cells. The organoids recapitulate tumor-specific characteristics and display inter-tumor heterogeneity. Here we explain how to establish the organoid cultures, maintain them in defined, serum-free medium and use them for patient-specific drug testing. Within 10-14 days, a patient-derived organoid culture is established and can be serially passaged. Compared to other protocols focusing on organoid cultures derived from pediatric kidney malignancies or healthy kidneys, the protocol described here is optimized for adult ccRCC organoid cultures. Organoids established using this protocol can be used to further investigate tumor biology in a complex 3D in vitro system, complement current preclinical model-based drug studies, and advance the development of personalized therapy design.

Background: Ras and Rab interactor 2 (RIN2) gene, encoding RAS and Rab interacting protein 2, can interact with GTP-bound Rab5 and participate in early endocytosis. Deletion of RIN2 may impair Rab5-related endosome signaling, leading to abnormal phenotypes. However, no research has been reported on the functions of RIN2 related to animal production.Results: A 61-bp insertion/deletion (indel) in the RIN2 intron region in this study. The genotype analysis of mutation sites was performed on 550 individuals from 7 different chicken breeds, and it was found that the indel exists in each breed and the local breed chickens are mainly DD genotypes. Correlation analysis of the indel with growth traits and carcass traits of the F2 population of Xinghua and White Recessive Rock chicken showed that the RIN2 61-bp deletion mutation site was significantly correlated with abdominal fat weight, fat width and hatching weight traits (P < 0.05). RIN2 mRNA was expressed in all test tissues, and the expression level of abdominal fat was higher than that in other tissues. In addition, it was further found that the expression level of type II RIN2 mRNA in abdominal fat was significantly different from that of ID type and DD type (P < 0.05). Conclusion: The results showed that the mutation was closely related to the abdominal fat-related and hatching weight traits of chickens, which may have certain reference value for molecular marker-assisted selection of chickens.
