The technology of large scale hydrogen transmission from central production facilities to refueling stations and stationary power sites is at present undeveloped. Among the problems which confront the implementation of this technology is the deleterious effect of hydrogen on structural material properties, in particular at gas pressure of 1000 psi which is the desirable transmission pressure suggested by economic studies for efficient transport. In this paper, a hydrogen transport methodology for the calculation of hydrogen accumulation ahead of a crack tip in a pipeline steel is outlined. The approach accounts for stress-driven transient diffusion of hydrogen and trapping at microstructural defects whose density may evolve dynamically with deformation. The results are used to discuss a lifetime prediction methodology for failure of materials used for pipelines and welds exposed to high-pressure hydrogen. Development of such predictive capability and strategies is of paramount importance to the rapid assessment of using the natural-gas pipeline distribution system for hydrogen transport and of the susceptibility of new alloys tailored for use in the new hydrogen economy.

The presence of Escherichia coli in drinking water is an indication of fecal contamination and can represent a risk of waterborne diseases. Forty-nine E.coli strains isolated from different sources of drinking water (distribution system, well, spring and mineral water) were placed into the phylogenetic groups A (15 strains), B1 (19 strains), B2 (2 strains) and D (13 strains). Approximately 30% of the strains analyzed belonged to groups B2 and D, which usually include potentially extraintestinal pathogenic strains. Moreover, the assignment of the strains to different phylogenetic groups indicates that different contamination events occurred in these waters. These results were compared with the distribution of E. coli strains isolated from two rivers and two dams into the phylogenetic groups. A significant difference was observed when the distribution of drinking water strains into the phylogenetic groups was compared to the results obtained from the Guarapiranga Dam and the Jaguari and Sorocaba Rivers. The results obtained in this work suggest that PCR-based methods can be used for a rapid assessment of potentially pathogenic E. coli strains in water samples.

ABSTRACTImmunization has been considered one of the greatest achievements in public health programs and with immunization a number of diseases can be reduced such as eradicating smallpox, eradicating polio, and significant progress in reducing the incidence of diphtheria, tetanus, whooping cough and measles (1). Right now immunization at the global level is stagnant at 86%. It is estimated that around 19.5 million children worldwide do not receive basic immunization (2). In Indonesia, an estimated 1.9 million children under 1 year were not fully immunized in 2015 (3) and as many as 242135 children were not immunized in 2016. To find out the Mother’s Behavior As A Public Health Postgraduate Student Of University Of Indonesia On Giving Children’s Immunization. This study used a qualitative method using the Rapid Assessment Procedure (RAP) approach located in the University of Indonesia's Public Health Faculty . The informant selection technique uses purposive sampling with the principle of appropriateness and adequacy. Data collection method is with Focus Group Discussion (FGD) 2 groups with each consisting of 6 postgraduate students from University of Indonesia's Public Health Faculty who have fully immunized. As triangulation source, interview conducted with postgraduate students who provide incomplete immunizations, postgraduate students who do not provide immunizations, and staff of the Ministry of Health, Immunization Directorate General of P2P. Nearly all informants had good knowledge, positive attitudes towards immunization is that only a small percentage of informants refused immunization. All informants agreed that media information is important for the success of immunization programs, especially to prevent issues or hoaxes about immunization. Most of the informants received support from their families to give their children immunizations so that the status of immunization for children was complete, but there were informants who did not get the support of their closest family wich is the husband, which made their child's immunization status incomplete. But family support and electronic media have a big influence in motivating mothers to immunize their children. It is recommended to be more careful in sorting the information so that children's and the environment health are maintained properly.Keywords : Immunization behavior, child immunization, mother's education

Rapid assessment of plant photosynthetic pigments content is an essential issue in precise management farming. Such an assessment can represent the status of plants in their stages of growth. We have developed a new 2 Dimensional-Convolutional Neural Network (2D-CNN) architecture, the P3MNet. This architecture simultaneously predicts the content of 3 main photosynthetic pigments of a plant leaf in a non-destructive and real-time manner using multispectral images. Those pigments are chlorophyll, carotenoid, and anthocyanin. By illuminating with visible light, the reflectance of individual plant leaf at 10 different wavelengths – 350, 400, 450, 500, 550, 600, 650, 700, 750, and 800 nm – was captured in a form of 10 digital images. It was then used as the 2D-CNN input. Here, our result suggested that P3MNet outperformed AlexNet and VGG-9. After undergoing a training process using Adadelta optimization method for 1000 epochs, P3MNet has achieved superior MAE (Mean Absolute Error) in the average of 0.000778 ± 0.0001 for training and 0.000817 ± 0.0007 for validation (data range 0-1).

The ongoing distribution of the pension system is on the threshold of losing its sustainability, financially, which has produced a deficit in the budget of the Pension Fund of the Russian Federation and the deflection of pension funds to the distribution system in 2014. This situation was to some extent caused by demographic risks. Funded systems could become the main instrument for mitigating the demographic problem of the distribution pension system. But the problem is, these systems are unprotected to demographic risks as well.The paper examines the effect of demographic uncertainty on funded pension systems. It describes the process necessary for the financial sustainability of a funded pension system under the force of demographic and macroeconomic factors. It explores the conformity of Russian funded pension systems and that of OECD countries with the status of financial sustainability in the time from 1958 to 2012, making a prognosis for the financial viability prospects.

Abstract Configuration of distribution system can be changed manually or automatically, by changing the status of the respective switching elements, with the aim of reducing power losses, increase system reliability, or improving the power quality. When changing the status of switching equipment it is necessary to satisfy the requirement for the radial and connected structure of the distribution network. Using the single criteria optimization it is possible to improve one of the characteristics of the distribution network, on the other hand by using multicriteria optimization it is possible to find a network configuration that enhances multiple distribution system characteristics at the same time. In this paper, a modification of the multi-criteria Gray Wolf optimization algorithm is proposed in order to create an efficient algorithm that can be implemented in the management functions of smart grid concept of modern distribution systems. The proposed reconfiguration algorithm was tested on standard symmetrical IEEE 33 test distribution network.

Introduction. The management of children in the acute period of severe mechanical trauma (SMT) requires multi-parameter monitoring, a constant assessment of the severity of the condition and the adequacy of intensive care. The abundance of heterogeneous information about the patient determines the need for the development of integrated indices, enabling the rapid assessment of the status and prognosis of the course of the traumatic disease. The assessment of the acid-base state (ABS) of the blood is one of the day-to-day components of multi-parameter monitoring. The aim of the study was to determine the effectiveness and validity of the integral homeostasis index (IHI) obtained on the basis of the results of the ABS testing, for assessing the clinical state, its dynamics and determination the prognosis of the outcome of an acute period of trauma in children. Material and methods. The study included 345 SMT patients. The determination of ABS indices with the automatic calculation of the IHI was routinely performed 2 or more times a day. The obtained values of IHI were expertly compared with the assessment of the severity of the condition and the dynamics of this evaluation in the acute period of the traumatic illness. Results. The study demonstrated 97% accuracy in the determination of the prognosis of the course of the traumatic disease and 93% coincidence with an expert assessment of the severity of the patient’s condition. The results obtained make it possible to recommend the use of IHI for the practical use in the department of anesthesiology and resuscitation under the conditions of a unified information system combining databases (an electronic medical history, a laboratory information system, and a prognostic status and outcome module integrated in the information system and operating in a continuous mode).
