An Overview of Surface Water Quality Influenced by Suspended Solid Content in the Sayung Waters, Demak, Indonesia
Authors: Wisha Ulung Jantama , Ondara Koko , Kusumah Gunardi
Published: October 2018

Abrasion which is occurred in the Sayung coast is triggered by a big role of climate change as well as the sea level rise and land subsidence. Resulting degradation ultimately affects changes in existing environmental conditions. This study has aim to determine the existing water based on biological and chemical content which is affected by increasing suspended solid content in the Sayung waters. Purposive sampling technique was applied, and data is analyzed both statistically and spatially. Suspended solid value has ranged 23,1-199,6 mg/L. Distribution of suspended solid was only simulated during low tide towards high tide phase with current speed has ranged 0-0.41 m/s. We found that dissolved oxygen value is quite high in several observation stations which indicates the fertile area with low pollution and blooming tendency. In the station which is dominated by a high suspended solid and turbidity found that the chlorophyll-a decreases. The increased rate of suspended solid is directly enhancing the turbidity and indirectly declines the photosynthesis activity and inhibits the oxygen cycle. Resulting in the primary productivity reduction in the Sayung waters

Published: October 2018

Kuta beach in Bali is a world-famous tourist destination has been suffering from marine litters (or debris) disaster almost every year. Mitigation efforts have been carried out by the local government started from educating the people as well as continuing mass cleaning campaigns for the stranded litters in the beach. The research has an objective to understand the physical processes of marine debris characteristics in Kuta such as its propagation and distribution along the coastline and in the water columns during the two different seasons (West Monsoon and Transitional seasons). A hydrodynamic model was developed to investigate the transport of marine litters from their sources by considering the tide-driven surface currents and wind. Field surveys were also conducted to assess marine litter’s characteristics in the surface and in the sea beds for both plastic and wood types of litters. Hydrodynamic simulation shows that the surface current ranging from 0.05 – 1.75 m/s is capable of transporting marine surface debris from Bali Straits and other sources in the South of Bali to Kuta during West Monsoon season. The collected litters during the West Monsoon season were four times larger in quantity. The concentration of litters in the seabed and in the water column is larger near to the coastline than further offshore. In the meantime, during Transitional season, Kuta was completely free from marine litters. Results from surveys also showed that the most effective measures for marine litters in Kuta is self-awareness of the people to keep the environment clean.

Recently, the interest in renewable ocean energy has been growing rapidly among the ocean researchers in Indonesia. In this paper, the pattern of tidal current in Madura Strait was analyzed and it is used as First we present the general information of the structure of Suramadu Bridge and explain the purpose of installing tidal current turbine between its piers. Second, we develop the numerical model of Madura Strait. The bottom topography of Madura Strait is digitized from bathymetry map produced by Indonesian Navy. A nested hydrodynamic model has been developed to refine the specific area of interest around the piles of the Suramadu Bridge. MIKE-21 program is then employed to simulate the tidal current that passes between the piles of the bridge. Next, we validate the model by conducting the field measurement of the speed of tidal current between pile no. 56 and pile no. 57. We deployed ADCP and measured the current speed for 15 days. The obtained data is then compared with the numerical model. The results show that the simulated currents has similar pattern with the measured data. We also discuss the characteristics of the simulated tidal current comparing with the ADCP results. Finally we estimate the possible produced power produced from the kinetic energy of the predicted tidal current of hydrodynamic.

Published: October 2018

Through globalization, countries aim to have a competitive advantage about trading and increasing financial opportunities in the global market with international collaboration and economic integration. In recent years, the emerging and expanding national economies like Brazil, Russia, India, China and South Africa have became key players and taken investors’ attention globally. In addition to these countries known as BRICS, Turkey is also another expanding national economy that attracts investors with strong economic growth in the last 20 years. Therefore, recently the idea of becoming one of the members of BRICS for Turkey has been considered. 

Nowadays, the index research studies which show the global competitiveness, rankings and detailed data profiles of the international markets are published by different authorities. One of the highly trusted authorities, World Economic Forum publishes Global Competitiveness Index every year.

The purpose of this study is to indicate similarities and differences among these 6 countries (BRICS-T) and also define comparison to each other based on the data from Global Competitiveness Index (2017-2018). In the process of analyzing the data, multidimensional scale has been used. According to the data of Global Competitiveness Index (2017-2018), the similarities are more likely to be found between Russia and Turkey while India and China also project similar features together. The most different features have been observed between Brazil and China. The similarities are based on detailed data company profiles of global competitiveness. In conclusion, the result shows that Russia and Turkey are seen as one group while China and India generate also another group together. On the other hand, Brazil and South Africa stand alone in their own groups. Key Words: Global Competitiveness Index, WEF, BRICS-T, Multidimensional Scale

ALTERNATIVE FOR THE AUTOMATIC AND SPACIALIZATION OF USLE TOPOGRAPHIC FACTOR IN WATERSHEDS

 

 

2 ABSTRACT

 

Among the factors of the Universal Soil Loss Equation (USLE), the topographic factor is that it is less close to reality and, usually, the models used for its determination presents high complexity. In this study, therefore, the main objective was to calculate the topographic factor of the USLE in a simplified way using techniques geographic information system (sig). For that, data from the Digital Elevation Model – DEM was used, derived from the SRTM (Shuttle Radar Topography Mission), so slopes and slope length were calculated by processing of the DEM matrix data, so the topographic factor was estimated. The topographic factor values varying from 0.21 to 9.88 with an average of 1.97. The GIS techniques showed efficient for estimating the topographic factor derived from DEM data base.

FRS4: options for wave freeboard
Authors: Brown Alan , Hewitt Martin
Published: October 2018

The fourth edition of flood and reservoir safety (FRS4) published in 2015 included the change that where an existing dam failed to meet the defined engineering standard, then a risk-based approach could be used as an aid to assessing the value (cost against reduction in risk) of undertaking works to meet the standard, or the extent of works required, if any, to reduce risk to ‘as low as reasonably practicable’. This paper summarises the key aspects of a case history with a risk-based approach to assessing the adequacy of freeboard, which was presented at the FRS workshop at the BDS conference at Swansea.
Methodology for predicting the properties of cement composites at different scales
Authors: Sindu B. S. , Sasmal Saptarshi
Published: October 2018

In order to meet new demands, the performance of cementitious composites needs to be altered scientifically, rather than on a trial-and-error basis. In this regard, a computational approach is proposed to predict the properties (modulus, strength and strain) of cementitious composites. The information from an analytical hydration model (at the lowest scale) is used for homogenisation and upscaled to obtain the properties of the cementitious composite. The proposed computational method has the unique characteristics of not only predicting the mechanical properties of the cement composite with reasonable accuracy, but is also able to trace how the properties evolve during the hydration process. The developed method is also extended to predict the strength and strain capacity of fibre incorporated cementitious composite. The analytically obtained results at each scale are validated through experimental investigations. The computational approach proposed and the findings of this study will assist the development of performance-based design of concrete composite.
Biomimetic cementitious construction materials for next-generation infrastructure

Published: October 2018

The resilience of civil engineering structures has traditionally been associated with the design of individual elements with sufficient capacity to respond appropriately to adverse events. This has traditionally employed ‘robust’ design procedures that focus on defining safety factors for individual adverse events and providing redundancy. As such, construction materials have traditionally been designed to specific technical specifications. Furthermore, material degradation is viewed as inevitable and mitigation necessitates expensive maintenance regimes. Based on a better understanding of natural biological systems, biomimetic materials that have the ability to adapt and respond to their environment have recently been developed. This fundamental change has the potential to facilitate the creation of a wide range of ‘smart’ materials and intelligent structures that can self-sense and self-repair without the need for external intervention which could transform infrastructure. This paper presents an overview of the development, application and commercial perspectives of a suite of complementary self-healing cementitious systems that have been developed as part of a national team and led to the first UK full-scale field trials on self-healing concrete.
Modelling for compressive buckling of reinforcing bars
Authors: Qiu Jianlei , Gong Jinxin , Zhang Qin , Feng Zhibin
Published: October 2018

Buckling of longitudinal bars is a common failure mode in reinforced concrete columns under earthquake, and can lead to the deterioration of structural seismic performance. In this study, a numerical method for predicting the average behaviour of reinforcing bars in compression considering the influences of buckling is developed. The bare reinforcing bar is divided into several segments, and a set of differential equations is established, in which both the material and geometrical non-linearities are taken into account. Then, a set of non-linear equations is derived by solving these differential equations and combining the conditions of geometrical compatibility and mechanical equilibrium so that the uniaxial compression stress–strain relations of buckling bars can be calculated numerically. The developed numerical method is verified against experimental data. The results of simulation and test are analysed; it is found that, unlike the case of elastic buckling, buckling of the reinforcing bars with commonly used bar length-to-diameter ratio usually occurs in the post-yield stage, and the degradation of post-buckling stress is mainly affected by the bar length-to-diameter ratio, the yield strength and the ultimate strength-to-yield strength ratio. Finally, a pseudo-material stress–strain relationship of a reinforcing bar in compression considering the effects of buckling is established by performing parametric analysis.
Seismic fragility analysis of retrofitted steel tanks considering corrosion
Authors: Tavakoli Joorabi Ali , Razzaghi Mehran Seyed
Published: October 2018

Several types of steel tank are used in industrial plants to store hazardous chemical products. Most of these are unanchored tanks that are not designed to withstand seismic loads. Many of the old process industries in high seismic hazard areas have launched retrofitting programmes for their components, especially cylindrical tanks. Providing mechanical anchors is a common strategy for the seismic retrofitting of cylindrical tanks and there are thus several existing pre-code tanks that have been retrofitted by the provision of anchor bolts. In this work, fragility analyses of pre-code and retrofitted tanks were conducted for existing broad tanks. The effects of steel corrosion were considered in the fragility analyses and 250 tank–earthquake non-linear analysis cases were considered. The results of the study revealed that shell corrosion is an important source of uncertainty in the seismic fragility analysis of tanks. Moreover, it was found that providing mechanical anchors is a suitable technique for preventing moderate to major damage states in broad tanks, but is not efficient at preventing minor damage, especially for small peak ground accelerations.

Published: October 2018

Background: A workshop was carried out to stimulate in the health-student a humanistic perspective on patient care. Summary of work: Three teachers prepared a workshop to discuss care and multiprofessional work in health, using the psychodrama framework. Summary of results:  14 students participated. They expressed their feelings and performed scenes based on movie clips that were showed to them. One of these scenes was remade after discussion. They were positively surprised with the workshop. Our results showed that the principal feeling that emerged was Empathy, and they were touched by the lack of humanity when we do our work mechanically. Lessons learned/ Conclusions: This kind of approach with the health students early and at different moments in their courses, can create a reflexive professional capable of working in a multiprofessional team with active methods and can make a difference to their training as professionals.

Purpose: Dry Eye Disease (DED) is part of several conditions, including Sjögren’s syndrome (SS) and no single test to diagnosis DED. The present study intends to evaluate whether a set of signs and symptoms of DED can distinguish: a) SS from other non-overlapping systemic diseases related to DED; b) primary and secondary SS. Methods: 182 consecutive patients with DED were evaluated under five groups: SS, graft-versus-host disease (GVHD), Graves' orbitopathy (GO), diabetes mellitus (DM), glaucomaunder treatment with benzalkonium chloride medications (BAK). Twenty-four healthy subjects were included as control group (CG). The evaluation consisted of Ocular Surface Disease Index (OSDI), Schirmer test (ST), corneal fluorescein staining (CFS) and tear film break up time (TFBUT). Indeed, a subset of DED patients (n=130), classified as SS1, SS2 and nonSS (NSS) by the American-European Criteria were compared. Quadratic discriminant analysis (QDA) classified the individuals based on variables collected. The area under Receiver Operating Characteristics (ROC) curve evaluated the classification performance in both comparisons. Results: Comparing SS with other diseases, QDA showed that the most important variable for classification was OSDI, followed by TFBUT and CFS. Combined, these variables were able to correctly classify 62.6% of subjects in their actual group. At the discretionof the area under the ROC curve, the group with better classification was the control (97.2%), followed by DM (95.5%) and SS (92.5%). DED tests were different among the NSS, SS1 and SS2 groups. The analysis revealed that the combined tests correctly classified 54.6 % of the patients in their groups. The area under the ROC curve better classified NSS (79.5%), followed by SS2 (74.4%) and SS1 (69.4%). Conclusions: Diseases that causes DED, and also SS1, SS2 and NSS are distinguishable conditions, however a single ocular tools was not able to detect the differences among the respective groups.

Aim. We investigated the influence of various cholinoceptive drugs on spontaneous activity of a brain at the intact rabbit and in the conditions of deficit of gonadal hormones, and also studied of reciprocal influence of cholinergic drugs on changes of character of a range of EEG at the intact and castrated rabbits.

Methods. Our researches were carried out on 32 rabbit males of breed the Chinchilla. Bipolar nichrome electrodes implanted to rabbits by stereotactic operaition into a caudate nucleus, a hippocampus and a reticular formation of a mesencephalon and also cortical monopolar chlorsilver electrodes with a diameter of 1 mm - to the optic and frontal area of cortex. Registration of EEG carried out in a shielded chamber with use of the electroencephalograph-analyzer EEGA-21/26 “Encephalan-131-03”. The averaged EEG range power was analyzed with a 60 s recording epoch. In 3 weeks after implantation of electrodes we studied the influence a number of cholinergic drugs on spontaneous EEG: M-cholinolytic metamizyl (1 mg/kg i.p.), N-cholinolytic gangleronum (5 mg/kg i.p.), inhibitor of acetylcholinesterase (AChE) galantamine (0.5 mg/kg i.p.). Registration was carried out in 1, 2 and 3 hours after an injection. Under the combined investigation of preparation galantamine was entered in 20 minutes after an injection of cholinolytics. Then, we carried out removal of a testis at rabbits — males under etherization. The spontaneous electric activity of a brain of that rabbits and influence of cholinergic drugs was registered in 30 days after operation of bilateral gonadectomy.

Result. The gonadectomy of Chinchilla rabbits causes the deceleration of EEG range power twice in comparison with intact animals in a chronic experiment. The analysis of influence of cholinoceptive substances on EEG showed that the most sensitive to the change of balance between M- and N-cholinoreceptors are cerebral cortex and caudate nucleus. The intensity of the activating effect accompanying blockade of M-cholinoreceptors is higher in cortical structures, than in subcortical nuclei in all animals. The reaction of caudate nucleus to the blockade of M-cholinoreceptors is the most sensitive among subcortical nuclei. It “answers” with increase in EEG range power. The blockade of N-cholinoreceptors in this structure after insignificant potentiating is followed by decrease of EEG range power. The activity of hippocampus is least dependent on the level of androgens in organism.

Conclusions. The analysis of influence of cholinoceptive substances on spontaneous activity of a brain showed that the most sensitive to change of balance between M-cholinoreceptors and H-cholinoreceptors were a cerebral cortex and a caudate nucleus. As at the intact as the castrated animals the expressiveness of the activating effect accompanying blockade of M-cholinoreceptors is higher in cortical structures than in subcortical nuclei.

Authors: Shabanov Petr D.
Published: October 2018

The Federal clinical recommendations on treatment of pulmonary tuberculosis with multidrug-resistanсe to micobacteruim tuberculosis contain of algorhythm of actions to correct negative side effects appearing in the process of chemotherapy after linezolid prescription. According to this algorhythm, if the negative side effects in form of myelosuppression (inhibition of blood development) or neuropathies are developing, administration of linezolid can be abolished, and the drug prescription can be recovered beginning the dose of 300 mg per day after normalization of blood analysis, under blood analysis control, and then with 2-fold increase of oral dose (300 mg twice a day) to prevent repetitive development of negative side effect. In this case, dispensary prescription of linezolid 300 mg is permitted for tuberculosis treatment. In the paper, a comparative analysis of usage of different doses of linezolid for tuberculosis treatment with argumentation to use median (300 mg) doses of linezolid has been done.

El objetivo del estudio es analizar una comunidad de práctica virtual no formal (carácter voluntario, no institucionalizado y sin programa) de Educación Física llamada (Re)Produce, como herramienta para la formación del profesorado. Para ello se llevó a cabo un estudio de caso centrado en la visión de 15 de los 63 miembros (entre los que se encuentran profesores universitarios, maestros de Educación Física en activo y alumnos en formación inicial). Los datos emergen de los tres primeros años de funcionamiento de la comunidad a partir del análisis del contenido de los foros, entrevistas semiestructuradas, y comentarios de los participantes al informe de investigación que se les presentó. Los resultados muestran ciertas ventajas y problemas de la asincronía y ubicuidad (posibilidad de participar a distancia y problema de la falta de contacto personal); la interacción escrita (conocimiento accesible en el tiempo, más elaboración del discurso pero, por otra parte más tiempo y más autocontención); y la flexibilidad y el carácter voluntario y abierto de la comunidad (ajuste a los intereses y necesidades personales a costa de una falta de sistematicidad y continuidad en el desarrollo de los temas).

Durante la etapa de educación primaria se produce un gran desarrollo de la personalidad de los niños, siendo un momento idóneo para que adquieran y forjen hábitos de vida saludables que perduren en su vida de adulto. Se propone así una investigación con el objetivo de analizar los estilos de vida de los escolares en las variables de ejercicio físico y alimentación saludable, realizando propuestas para combatir uno de los grandes problemas de la población infantil del siglo XXI: la obesidad. Participan en el estudio un total de 310 alumnos (174 niños y 136 niñas), con edades comprendidas entre los 9 y los 12 años (5º y 6º curso) de 6 centros de educación infantil y primaria de la ciudad de Santiago de Compostela. Se emplea como instrumento de recogida de datos un cuestionario Ad Hoc de 19 ítems para medir la dimensión de alimentación saludable (9 ítems) y de actividad física (10 ítems). Los resultados muestran una tendencia de los estudiantes a consumir alimentos hipercalóricos en el recreo, una escasa práctica de actividad física semanal y el uso intensivo de las nuevas tecnologías, tendiendo de esta forma al sedentarismo y, consecuentemente, al aumento de la obesidad infantil. El fomento y adquisición de hábitos de vida saludables debe constituir una prioridad de las administraciones públicas, de las familias y de los propios docentes, haciendo un frente común para frenar los altos índices de obesidad infantil e invertir esta tendencia.

Background: Manually importing and analyzing image data can be time-consuming, prone to human error, and costly for large clinical trial datasets. This can lead to delays in quality control (QC) feedback to imaging sites and in obtaining data analysis results. Herein we describe the creation and application of a high-throughput review process for import, classification, labeling and QC of large multimodal clinical trial image datasets.

Methods: Automated methods were used to remove patient identifying information, extract image header data, and filter image data for usability. A convolutional neural net was applied to estimate anatomy for CT images. Internal scores were assigned for each image series to identify the optimal series for labeling and reading of each anatomical region. Image QC reports were automatically generated for all patients.

Results: In combined studies for which 204,492 series were received, 27,841 series were identified as usable and 13,415 series were labeled. Using this high-throughput method, total work-hours required per time point were reduced by an approximate factor of ten when compared to traditional review and labeling methods. Our anatomic classification system identified 95.7% of image series correctly, with the remaining series being manually corrected before labeling and analysis.

Conclusions: A high-throughput image analysis pipeline was implemented in a large combined dataset of clinical trial image series. This pipeline can be applied across other studies and modalities for fast image data characterization, labeling and QC.

Authors: Gorantla Naga Rekha , Mungila Hillemane Bala Subrahmanya
Published: October 2018

Developing new medical devices require extensive clinical investigations to enter the market successfully. In recent years, India has emerged as one of the attractive and most preferred countries to carry out clinical trials, primarily due to diverse human gene pool and cost-competitiveness. However, unlike other healthcare products such as therapeutic drugs, there is a lack of regulations over usage of medical devices. Moreover, prior systematic empirical analysis that examine the medical device based clinical trials is also not well established. This study attempted to ascertain the determinants of participant recruitment, selection of locations and time taken to conduct medical device clinical trials. Medical devices that are clinically tested in India in the period of 2008 to 2014 were obtained from CTRI website. 108 out of 279 records were identified as medical device clinical trial registrations. Collected data was analyzed to know the device type, disease category, sponsors involved, participant enrolment, locations and the duration of the device trial. In this study, the category of sponsorship, device type and disease category were found to have significant influence with respect to the selection of number of participants, locations and the time taken to execute medical device clinical trials.

Published: October 2018

Background: Breastfeeding is a healthy, safe and economical way of providing proper and wholistic nutrition to the newborn. It reduces incidences of infection in the respiratory, gastrointestinal systems and systemic infections. As will as it deepens the bond between the mother and her child, and also it offers a number of health benefits to the mother. Despite these profound advantages, it remains under-fulfilled and sometimes missed altogether. The aim of the study is to assess the knowledge about breastfeeding benefits among mothers.Methods: The study involved 397 mothers visiting general pediatrics clinics at Maternity and Children Hospital of Buraidah, Qassim Region, Saudi Arabia from 18 March 2018 to 18 April 2018.Results: Most of the surveyed women were Saudi (93.5%), (46.1%) university or higher education level. (12.3%) rely on breastfeeding as the only source. (23.9%) were breastfeeding for more than 6 months. Some questions had as high correct answers as (49.2%), while others had as low correct answers as (20.4%), university or higher education level have the highest correct answers (73%). (61%) discussed the benefits of breastfeeding with a doctor and the correct answers were (72%) while (39%) didn't discuss and the correct answers were (65%).Conclusions: Analysis of the collected material on the surveyed women showed that Saudi women have insufficient knowledge about breastfeeding. Knowledge is improving after discussing with a doctor about breastfeeding benefits. Based on these results we highly recommend increasing the efforts to promote and endorse the benefits of breastfeeding by pediatricians and other health professionals.
