Wave power absorption by an oscillating water column (OWC) device of annular cross-section in a combined wind-wave energy system

This paper deals with a new combined concept consisting of an oscillating water column (OWC) device and an offshore wind turbine for the multi-purpose utilization of offshore renewable energy resources. The wind turbine is supported by a monopile foundation, and the attached OWC is coaxial with the foundation. Within the chamber, the exterior shell of the OWC and the monopile foundation are connected by four vertical stiffening plates. Correspondingly, the whole chamber is divided into four equivalent fan-shaped sub-chambers. A higher-order boundary element method is then adopted to model the wave interaction with the combined system. Numerical models based on two different approaches, namely ‘Direct’ and ‘Indirect’, are both developed in this study. In addition, a self-adaptive Gauss integration method is developed to treat the nearly singular integration that occurs when the field and source points are very close to each other. A detailed numerical analysis is then conducted for the case of an OWC integrated into a NREL 5 MW wind turbine in both regular and irregular sea states. Numerical results illustrate that a significant energy extraction efficiency is attained when remarkable piston-like fluid motion is induced within each sub-chamber, and the wave power absorption by the OWC is not restricted by wave direction. The air compressibility makes a negative effect on the wave power absorption especially when the wave frequency is less than the resonance frequency of the piston-mode motion of the fluid in the chamber. In addition, the wave forces on the OWC and the monopile can balance each other at specific wave conditions, leading to a nearly zero net wave force on the whole system. The results also illustrate that by using an optimal turbine parameter, the wave power production by the OWC can be an important supplement to the combined system in operational sea states.

A MODEL FOR URBAN FOREST MANAGEMENT PLANNING: ISTANBUL CASE STUDY

Urban forests have become important elements of cities green fabric providing many ecosystem services including recreation. In this study, we proposed a model for urban forest management planning in the example of Istanbul, where urban sprawl has transformed the green infrastructure of the city dramatically. To this purpose, a total of 201 surveys were conducted through faceto-face interviews including those working as managers and technical staff in the forestry organization in Istanbul, academicians and NGOs. Subjects to be surveyed were determined according to the layered-simple random sampling method. The data were evaluated by descriptive statistics based on a variety of opinions about urban forest management planning in Turkey along with various socio-economic variables (gender, profession and experience). Whether there was any statistically significant difference between the groups was determined by Kruskal-Wallis H-Test. In case a difference was found, Duncan s Multiple Range Test was applied to detect the group(s) significantly different from each other. The results revealed that mainly males agreed on the purpose of urban forests as addressing recreational and social needs. All groups highlighted the lack of coordination and poor management system as main problems, while experienced and male subjects addressed that a new urban forest law is necessary. Mainly academicians and representatives of NGO s and related institutions suggested redefining the concept and restructuring the legislation concerning urban forests. In terms of activities, the majority favored hiking and sightseeing activities (51%), photography (42%), and extreme sports (37%). There was an emphasis on the need for sufficient number of hiking, climbing and cycling trails and botanical gardens. As a result, a model plan based on sustainable resource management ensuring multi-purpose utilization was proposed.

Получение обогащенной L-аргинином древесной зелени при проведении лесохозяйственных мероприятий в молодняках сосны обыкновенной (научный обзор)

Forests produce a huge amount of organic matter, which is a source of renewable raw materials for the production of technical, feed, food and pharmaceutical products. The logging and woodworking industry in Karelia, as in Russia as a whole, is based exclusively on stem wood. Woody greens are formed while felling ripe and over-mature stands, thinning and implementation of measures for the conservation, protection and reproduction of forests including forest stands cutting. The development of technologies for the use of woody greens is necessary for the multi-purpose utilization of the entire phytomass produced by forest plant communities. An additional economic incentive for young stands thinning and limbing, that are used to improve the quality of logs, is the ability to reduce costs or even ensure the profitability of these measures driven by the development of processing plants and the use of wastes generated during transportation: thinners, low-quality and low-value decidous wood, woody greens, that are raw materials for the production of biologically active preparations of various action. The urgent tasks are to increase the use of importsubstituting pharmaceutical substances and to search the alternative methods for producing raw materials for nutrient mixtures and feed stuff. Technologies for modifying the biochemical composition of coniferous greens, resulting in production of plant raw materials enriched with target biologically active substances, are being developed for the exploration of new plant sources. The water-soluble fraction of coniferous greens contains free amino acids, in particular L-arginine, which plays an important role in the life of animals. A promising way is to increase the free amino acids content in coniferous raw materials and change their quantitative ratio by regulation of the mineral nutrition regime of woody plants. An original scheme of additional supply of coniferous plants with nitrogen and boron is proposed in order to obtain coniferous greens enriched with L-arginine. The use of conifers as bioproducers of L-arginine and the study of its metabolism with reference to climatic factors, conditions of mineral nutrition, seasonal and daily dynamics in the natural environment, the search for ways to increase its level in organs and tissues is of current interest both on the theoretical and practical sides. Obtaining coniferous greens enriched with L-arginine will allow organizing the production of coniferous products for nutrient and pharmaceutical use. It is necessary to analyze the potential sources of raw materials taking into account their availability, costs for enriching the needles with L-arginine and product yield per unit area to assess the economic feasibility of organizing such production. A developed sequence of forestry measures will make it possible to obtain needles enriched with L-arginine, both in the process of implementing various types of forest use, and in carrying out activities aimed at increasing the productivity of forests and preserving their useful functions. Herewith, it is possible to turn costly cleaning and fertilizing of young Scots pine stands into profitable ones with additional products. Technologies of intentional changes in the chemical composition and pharmacological properties of plant raw materials obtained from woody plants will allow the development of new raw materials for biologically active substances.

Study of Communication & Social Space at ‘Salons’ in the Aged Society of Japan

The purpose of this study is to understand the meaning and role of salons, a social space operating in Japan, which has recently become a super-aged society. The data for this study were collected through a literature review and through field visits. The literature survey analyzed 23 cases of salons in detached housing areas, and the field survey was conducted at salons in five apartment housing complexes with an elderly ratio of more than 40 percent in Tokyo, Japan. The survey details include the use of salons, operation methods, modification status, appearance characteristics of buildings, facilities and spaces, and activities. According to the analysis of the 23 salons in the detached housing area, the uses of these spaces included child care, rest for caregivers, multi-purpose utilization for conversations and meetings, hobby activities, a library, and a gallery. There were multiple functions of the five salons at the apartment housing complexes, included for conversations, gatherings, meals, and to obtain information. Based on Japan"s various salons, it is believed that the use of idle resources such as salons in the regions under study can continue to have the effect of preventing social problems such as loneliness caused by the isolation of the elderly to realize a more prepared aged society in the future.

Framework for multi-purpose utility tunnel lifecycle cost assessment and cost-sharing

The traditional method of buried utilities (i.e. water, sewer and gas pipes, and electrical and tele-communication cables) has been using for many decades particularly in urban areas. Repeated excavations are needed to access these underground utilities for maintenance, repair, and renewal activities. Urban areas have been experiencing many street closures and traffic disruptions because of excavation for maintaining underground utilities. These construction works have imposed major costs on public and private utility providers as well as on citizens and local businesses (social cost).Multi-purpose Utility Tunnel (MUT) was introduced as a solution that not only avoids these excavations, but also facilitates inspection and protects utilities. However, MUT is not widely used in most of the countries, because of the high initial investment, safety and security issues, complicated design and construction, and complex coordination of utility companies. Despite the higher design and construction cost of MUT, operational cost-savings can justify the investment from the project point of view. From the organization's point of view and based on cost-sharing, MUT should be more economical as well and the MUT benefits should be distributed fairly, to convince utility companies to participate in the MUT project. Lifecycle Cost (LCC) analysis of MUT and buried utilities method is complicated because of various factors that influence LCC. This paper aims to develop a comprehensive and systematic model for MUT and buried utilities LCC analysis by considering the influencing factors. The output of this model determines the LCC of MUT and buried utilities to ensure the project decision-makers that MUT is the economic method. This model also proposes a model of MUT cost-sharing to ensure the decision-makers of utility companies that MUT is the economic method for their company and also all the utility companies benefit from MUT fairly. This model defined the fairness based on three principals: (a) balance of risk, (b) balanced benefit-cost ratio, and (c) balance in contributed benefit and gained benefit. It is expected that the proposed model promotes using MUT by facilitating economical analysis and decision making for MUT projects from project and organization points of view.

Assessment of genetic variability in different kenaf (Hibiscus cannabinus) germplasm using morpho-agronomic traits

Kenaf (Hibiscus cannabinus L.) is a fiber crop classified in the genus Hibiscus (Malvaceae), and has a great potential for its multipurpose utilization, in addition to its traditional usage. Varietal identification of kenaf is always problematic and knowledge on genetic variability of kenaf varieties is also limited, which significantly hindered our effective utilization and conservation of the valuable kenaf germplasm. In order to find a proper method for identifying kenaf varieties and studying their variation, morpho-agronomic characters were analyzed. Fifty eight accessions of kenaf germplasm collected from Gene Bank Department of Bangladesh Jute Research Institute were characterized at Jute Agriculture Experiment Station, Manikganj during April 2014 to December 2014. The accessions were characterized for fifteen morpho-agronomic attributes as per Hibiscus descriptor in order to select superior genotypes for the genetic improvement of kenaf. Considerable ranges of variability were observed in stem colour, petiole colour, plant height, base diameter, dry fibre weight, dry core weight, green weight with leaves and green weight without leaves. Based on major yield contributing characters accessions 1653, 3384, 3928 and 4202 performed better than the control varieties HC-2 and HC-95.

Delignification and Ionic Liquid Treatment of Wood toward Multifunctional High-Performance Structural Materials.

Wood-based multifunctional materials with excellent mechanical performance are increasingly considered for sustainable advanced applications due to their unique hierarchical structure and inherent reinforcing cellulose phase orientation. Nonetheless, a wider multipurpose utilization of wood materials is so far hampered because of constraints arising from scalable functionalization, efficient processing, facile shaping as well asnatural heterogeneity and durability. This study introduces a multifunctional all-wood material fabrication method relying on delignification, ionic liquid (IL) treatment, and pressure-assisted consolidation of wood. Structure-retaining controlled delignification of wood was performed to enable direct access to the hierarchical cellulose assembly, while preserving the highly aligned and thus beneficial wood structural directionality. As a following step, the obtained biobased scaffold with an increased porosity was infiltrated with an IL and heat-activated to partially dissolve and soften the cellulose fiber surface. Samples washed with water to remove IL exhibited pronounced isotropic flexibility, which upon combined compression and lateral shear allowed the fabrication of various 3D shapes with adjustable fiber architecture. The obtained very compact and totally additive-free all-wood materials were extensively characterized, revealing superior mechanical performance, and gained multifunctionality compared to native wood.

The diversity of fatty acid composition in traditional and rare oil crops cultivated in Russia

This review is devoted to the description of chemical peculiarities of industrial oil crops cultivated (or prospective for cultivation) in Russia, which are stored in the VIR collection. Different crops have similar fatty acids biosynthesis pathways, but each species has its own individualities in the chemical composition of the oil and its genetic control. The diversity of oil crop chemical composition opens the possibility of its multipurpose utilization practically in all industrial segments. Sunflower, rapeseed, flax, mustard, camelina and safflower are cultivated in Russia as oil crops. Castor beans, perilla, lallemantia and noog are not cultivated on an industrial scale, but have original oil properties and are prospective for future cultivation. Hemp and poppy seeds contain oil valuable for food, but they are not widespread. Cotton and peanut oils are prospective for industrial purposes when early, already created varieties of these crops will be cultivated in Russia. Oil properties depend on the ratio of its basic fatty acids: saturated (stearic, palmitic) and unsaturated (oleic, linoleic, linolenic). As a rule, lauric, myristic and palmitoleic acids are determined in minor quantities. The oil of Brassicaceae crops also includes arachidic, eicosenoic, eicosadienoic, behenic, erucic and lignoceric acids. Fatty acids accumulation is influenced by growing conditions, though it has strict genetic control.

Определение влияния антифрикционных компонентов на трибологические свойства резьбовых покрытий

Within the development of a material, which forms a multifunctional coating on the threaded surface of tubes and joints, the authors identified the requirements specified for a coating. One of the main requirements is the possibility to perform the repetitive screwing of threaded connections without thread damage. The necessity to obtain a high level of anti-friction properties of a coating aroused the study of the influence of anti-friction additives of various effect on the tribological properties of a coating: the decrease in the friction coefficient of conjugate surfaces and ensuring the abrasion resistance of a coating. To identify the influence of anti-friction additives of various effects on the functional properties of a coating, the authors carried out the comparative laboratory tests of thread coatings containing various anti-friction additives under the sliding friction at the reciprocation according to the “fixed plate - finger” scheme. As the anti-friction components, the authors used graphite, molybdenum disulfide, and polytetrafluoroethylene (PTFE), which have different anti-friction properties. The tests were carried out for the coatings containing the complex of additives as well: graphite - PTFE, molybdenum disulfide - PTFE. The authors evaluated the tribological properties of the resulting coatings according to their friction coefficient value and abrasion resistance. To select optimum concentrations of anti-friction components, the authors tested the materials containing the complex of additives with different concentrations of graphite and molybdenum disulfide. To confirm the results of laboratory tests, the authors carried out full-scale tests in the factory environment when applying the selected coating to the threaded surface of a tube and a joint. The research identified the positive effect of the multipurpose utilization of anti-friction components. The authors determined the systems of anti-friction components (graphite - PTFE and molybdenum disulfide - PTFE) and their optimum concentrations (graphite and molybdenum disulfide - 8 wt. %, PTFE - 6 wt. %) in the thread coating material. The full-scale tests in the factory environment confirmed the results of laboratory tests.

Hydrodynamic performance of an offshore-stationary OWC device with a horizontal bottom plate: Experimental and numerical study

As an example of multipurpose utilization of marine structures, the hydrodynamic performance of an offshore-stationary Oscillating Water Column (OWC) device with an immersed horizontal bottom plate was investigated through both experimental tests and numerical simulations. Based on the open source package OpenFOAM and toolbox waves2Foam, the numerical results were validated by comparing them with experimental data. The effects of the opening ratio (a), plate length (D), relative opening (ε), and water depth on the energy absorption efficiency, transmission coefficient, and energy dissipation coefficient were examined over a wide range of wave conditions. The results show that a relatively long bottom plate and small opening ratio is beneficial for both the energy extraction and wave-damping ability, especially for long waves. Increasing the relative vertical opening considerably improves the performance of multipurpose OWC devices. Moreover, the optimal structure configuration is found for parameters a=0.65%, D=2B (B is the breadth of chamber), and ε=1/2.

Integrated system of thermochemical cycle of ammonia, nitrogen production, and power generation

Ammonia (NH3) is one of the most valuable chemicals due to its multipurpose utilization in many applications. Beside major application as fertilizer in agriculture, NH3 is a promising hydrogen (H2) carrier because it has a high content of H2 and technically available storage and transportation systems. At present, most of NH3 is synthesized from a series of steam reforming process to the feedstock of H2 and nitrogen (N2) production, followed with the catalytic Haber-Bosch reaction. In this study, an integrated system of N2 production system, NH3 synthesis system and a power generation process is proposed to produce NH3 efficiently. Thermochemical cyclic process of an endothermic reaction of Al2O3 reduction by carbon in N2 atmosphere, is coupled with oxidation/steam-hydrolysis of aluminum nitride (AlN) back to Al2O3, producing NH3 without catalyst and the need of H2 production system. The thermal energy required for reduction reaction is covered by the heat generated during exothermic reaction and combustion process, and the remaining heat is utilized in power generation. Heat circulation optimization is carried out by applying the enhanced process integration, resulting in a highly efficient system. The proposed system is analyzed through an adjustment of the main parameters: oxidation temperature, steam turbine inlet pressure, and temperature, to observe their effect on system performance and efficiency. The proposed system can reach a very high system efficiency of 69.3%. The oxidation reaction temperature is observed to play major role in determining the system performance due to temperature dependent NH3 yield.

Privacy-aware relationship semantics–based XACML access control model for electronic health records in hybrid cloud

State-of-the-art progress in cloud computing encouraged the healthcare organizations to outsource the management of electronic health records to cloud service providers using hybrid cloud. A hybrid cloud is an infrastructure consisting of a private cloud (managed by the organization) and a public cloud (managed by the cloud service provider). The use of hybrid cloud enables electronic health records to be exchanged between medical institutions and supports multipurpose usage of electronic health records. Along with the benefits, cloud-based electronic health records also raise the problems of security and privacy specifically in terms of electronic health records access. A comprehensive and exploratory analysis of privacy-preserving solutions revealed that most current systems do not support fine-grained access control or consider additional factors such as privacy preservation and relationship semantics. In this article, we investigated the need of a privacy-aware fine-grained access control model for the hybrid cloud. We propose a privacy-aware relationship semantics–based XACML access control model that performs hybrid relationship and attribute-based access control using extensible access control markup language. The proposed approach supports fine-grained relation-based access control with state-of-the-art privacy mechanism named Anatomy for enhanced multipurpose electronic health records usage. The proposed (privacy-aware relationship semantics–based XACML access control model) model provides and maintains an efficient privacy versus utility trade-off. We formally verify the proposed model (privacy-aware relationship semantics–based XACML access control model) and implemented to check its effectiveness in terms of privacy-aware electronic health records access and multipurpose utilization. Experimental results show that in the proposed (privacy-aware relationship semantics–based XACML access control model) model, access policies based on relationships and electronic health records anonymization can perform well in terms of access policy response time and space storage.

Genotypic diversity for fruit characteristics in bael [Aegle marmelos (L.) Corr.] based on principal component analysis

Bael is a medicinal cum fruit tree with multipurpose utility and propagated mostly through seeds. It is mostly found in India, Sri Lanka, Myanmar, Bangladesh, Thailand and China. Focus on collection of bael variability has increased in recent times with an aim towards their utilization as fresh or made into ‘Sharbat’, one of the most popular drinks in the Indian. Its lots of evidence have showed immense potential of nutritional and medicinal properties used in various ethnic societies. The present investigation was carried out to exploit genetic variability in bael fruits. Seventy-five genotypes were characterized for sixteen fruit traits viz. fruit weight, fruit length, fruit width, skin weight, no. of seed, seed weight, pulp weight, skin per cent, seed per cent, pulp per cent, skin thickness, fruit volume, TSS, acidity, reducing sugar and total sugars during 2015. Observations of growing seedling trees showed rich genetic variations regarding their fruit characteristics. The fruit characteristics, viz., fruit weight ranged from (315.20–1608.65 g), fruit length (81.39–173.43 mm), fruit width (89.76–136.35 mm), skin weight (88.62–358.07 g), number of seed (37.67–195.40), seed weight (7.48–54.33 g), pulp weight (201.17–1243.87 g), skin % (9.59–42.83%), seed % (0.97–7.97%), pulp % (53.72–89.33%), skin thickness (1.43–4.10 mm), volume of fruit (285.00–1555.00 cc), TSS (24.40–47.80°Brix), acidity (0.15–0.40%), reducing sugar (0.37–11.90 mg/100 g) and total sugars (7.14–20.83 mg/100 g) among the different genotypes. On the basis of overall assessment, one genotype, ICAR-RCER BS 6/1 was found to be the most promising. Based on fruit properties, principal component analysis (PCA) was performed to qualitatively and quantitatively discriminate the germplasm difference. Eight principal components, which contribute 94.80% of the total variability, were selected for analysis. Biplot between PC1 and PC2 showed that genotypes namely ICAR-RCER BS 6/1, 18/2, 25/5, 21/1, 17/3, 26/1, 18/5, 1/11, 8/1 and 14/4 were very different from each other.

M-generalization for multipurpose transactional data publication

Transactional data collection and sharing currently face the challenge of how to prevent information leakage and protect data from privacy breaches while maintaining high-quality data utilities. Data anonymization methods such as perturbation, generalization, and suppression have been proposed for privacy protection. However, many of these methods incur excessive information loss and cannot satisfy multipurpose utility requirements. In this paper, we propose a multidimensional generalization method to provide multipurpose optimization when anonymizing transactional data in order to offer better data utility for different applications. Our methodology uses bipartite graphs with generalizing attribute, grouping item and perturbing outlier. Experiments on real-life datasets are performed and show that our solution considerably improves data utility compared to existing algorithms.

Designing Entrustable Professional Activities for Training Health Professional Educators: a Review of Current Practices

Faculty development substantially contributes to improving the proficiency of health professional educators. However, most training programs are designed around institutional or individual wish lists, from which the assessment of teaching competence is often missing, resulting in the decreased effectiveness of the entire exercise. With an increased call in the literature to introduce structured assessment to faculty development, few initiatives have been taken in which entrustable professional activities are utilized in the teacher training framework. The current article aims to review existing teacher training programs that have incorporated entrustable professional activities (EPAs) in their frameworks and aims to provide further insights into how to adopt the concept of EPAs in faculty development. The literature was searched through the electronic Scopus and PubMed databases using the terms faculty development program, faculty training, teacher training, and entrustable professional activities. The literature search was performed from 2005 to 2018. The search yielded 243 articles in Scopus and 236 articles in PubMed. Studies were excluded that focused on the usage of entrustable professional activities in undergraduate or postgraduate clinical training programs. Of the 479 results, only nine were found to be relevant to EPA-based faculty training programs. Introduction of entrustable professional activities to the domain of faculty training is fairly recent. Only two programs were found in our search that used the concept of EPAs in their training frameworks. One is the Master in Health Professions Education program at the University of Michigan (UM-MHPE), and the other is the Fundamental Teaching Activities (FTA) framework designed for Canadian medical teachers. Current practices reveal fascinating insights into the utilization of EPAs for faculty training. Both the UM-MHPE and FTA frameworks effectively address teaching tasks and competencies. However, despite the multipurpose utility of these frameworks, a few limitations may exist. For instance, these frameworks share limited details about EPAs’ content and their utility in assessment protocols. Moreover, specific teaching domains—such as a problem-based learning (PBL) tutor, mentor, and/or researcher—have not been addressed in the current examples. A need remains for an EPA framework design that can cover missing teaching domains.

Distribution characteristics, resource utilization and popularizing demonstration of crop straw in southwest China: A comprehensive evaluation

The resource utilization of crop straw, as a part of energy development strategy, is important in term of economy and environmental protection. Based on statistics for agriculture and data, the distribution characteristics, resource utilization, and popularizing demonstration of crop straw in southwest China were comprehensively evaluated. Occurrence of the straw during the last ten years in the Socio-economic Development Region (SEDR) was estimated. On the basis of it, the critical problems during the utilization processes and the multipurpose utilization technologies of crop straw were discussed. Results showed that theoretical straw yield in southwest China in 2015 was 8.2 × 107 t, and corn straw accounted for 54.28% of the total. The order of the straw yield was corn > rice > bean in the three southwest provinces. At present, crop straw is mainly used as soil amendment, fertilizer, fodder, industrial materials, biogas, and power generation. Moreover, the straw fermentation should be also promoted for ecological agriculture. Current progress in straw resource utilization in the innovative demonstration area, namely Liupanshui Agricultural District (LAD), was illuminated. Resource and utilization of crop straw, via biogas production, feedstuff, and returning to field, was about 82% of the total. At the strategic level, regional SEDR system planning should be overall planed in agricultural field, and it is a critical part of the coordinated development of straw utilization. Through the master plan practice of the demonstration area, the suggestions on state modern construction system of agricultural waste were raised.
