Securing a sustainable production nowadays is a key issue taking into account the need for clean and sustainable solutions for the production of magnesium, in order to avoid harm to the environment. Redesign of secondary magnesium metallurgy in the complex Mg Serbien is presented. The integrated approach has been pointed in order to deliver industrial sustainability which significantly contributes to the material flows management and cleaner production, as well as preventive measures for environmental management. The research propose is to show that sustainable magnesium production is feasible only by principles of closing the production cycle through optimization and synergy between primary and secondary magnesium production in order to generate as least as possible waste, emission and pollution. The technical and economical view-point evaluation has been illustrated by material balance sheets and economic parameters which are the most favorable parameters for projects of this kind. The unit capital expenditures and unit operating expenses are indicators of the economic success for this integrated approach by using UNIDO and the World Bank methodology.

Behavioral Activities

Accurately predicting when calving will occur can provide great value in managing a dairy farm since it provides personnel with the ability to determine whether assistance is necessary. Not providing such assistance when necessary could prolong the calving process, negatively affecting the health of both mother cow and calf. Such prolongation could lead to multiple illnesses. Calving is one of the most critical situations for cows during the production cycle. A precise video-monitoring system for cows can provide early detection of difficulties or health problems, and facilitates timely and appropriate human intervention. In this paper, we propose an integrated approach for predicting when calving will occur by combining behavioral activities extracted from recorded video sequences with a Hidden Markov Model. Specifically, two sub-systems comprise our proposed system: (i) Behaviors extraction such as lying, standing, number of changing positions between lying down and standing up, and other significant activities, such as holding up the tail, and turning the head to the side; and, (ii) using an integrated Hidden Markov Model to predict when calving will occur. The experiments using our proposed system were conducted at a large dairy farm in Oita Prefecture in Japan. Experimental results show that the proposed method has promise in practical applications. In particular, we found that the high frequency of posture changes has played a central role in accurately predicting the time of calving.

Geological Map

A considerable amount of coal deposits occur within the Mesohellenic Trough in Greece. It is considered as the largest and most important basin of the last orogenic stage of the Hellenides, which is interpreted as a back-arc basin that evolved during the period of Late Oligocene to Miocene. In this study, a simplified geological map has been constructed emphasizing on the coal formation occurrences of the Mesohellenic Trough. This work has been accomplished, through Geographic Information Systems (GIS) and has been organized via geodatabase as GIS data files (feature classes). For the creation of the geological map suitable homogenization and discrete representation has been implemented different geological sheets, original source and traditional maps. Next step was the geostatistical analysis using polygonal methods linked to the corresponding tabular information. Regarding the stratigraphical age, and petrographic data related to geographic distribution of the coal occurrences, these are divided into three categories: Oligocene, Middle Miocene and Upper Miocene coals, exhibiting various physicochemical and topological properties. Upper Miocene coal exhibits the greatest area and perimeter values, while the lowest values correspond to those of the Middle Miocene. Terrain models such as aspect (angle-direction) and hillshade (shaded relief) showed the spatial relation between coal occurrences and morphotectonic as long as geometrical characteristics of the study area. Coals are mainly classified as huminites including mainly huminite group minerals (90%). Their S contents can probably derive from parent plant material or a combination of parent plant material with seawater sulfates. Moisture contents are strongly connected with the sustainability of the coal use in the energy production, while their carbonation grade is strongly associated with their age and expressed by their reflectivity values. All these data have been inserted in an integrated database and can be useful for pre-mining or post mining activities (e.g. planning, analysis, management, restoration). Results of this study are available for the effective evaluation of the existing coal occurrences, which can be used with renewable energy sources providing sustainable solutions, in combination with the upcoming innovative CCS and CCU technologies. Results also showed that coals from the Mesohellenic Trough present excellent quality traits. However, their value as combustible coal is very low due to the absence of economically recoverable reserves. The largest coal lenticular bodies have been extracted in the past and the remaining occurrences do not exceed several thousand tones. Based upon existing literature and from geospatial estimations, coal deposits in the Mesohellenic Trough Basin cannot be considered as economically valuable for exploitation.

Lithuania has had a significant reform path in the last twenty-five years like other communist bloc countries during the intense changes in the world. Changes and transformations took place in various areas including social security system. Since 2004 have been significant developments legalizing the three-pillar old age pension system supported by the World Bank. Currently, the pension funds operating more than ten years and their assessment still have not stopped being the centre of numerous discussions. There are ongoing discussions about the fund performances’ benefit, efficiency and its evaluation. Therefore, this paper investigates the funds’ valuation problem by testing II pillar pension’s funds in Lithuania. We use the multi-criteria methods with two scenarios: first we estimate II pillar pension’s funds by applying a return (as well as the added value) and the risk indicators; second we include only the most popular derivative indicators: Sharpe, Treynor and Jensen’s alpha ratios. Our results indicate that based on the second scenario methodology is more precise evaluated II pillar pensions funds’ performance, but funds evaluation model based on multi-criteria assessment is more appropriate for larger funds groups. However, in order to assess the performance of the funds and compare them with each other it is important not only use the mathematical methods but also to maintain a holistic approach which allows to integrate micro and macro environmental factors into the funds’ assessment.

The revitalization of Toronto’s waterfront presents the largest urban redevelopment project currently underway in North America. With respect to planning the waterfront’s urban water systems (UWS), a number of studies considered a range of criteria in search for sustainable alternatives. However, a comprehensive assessment of the integrated source-drinking-wastewater-stormwater systems over their life cycles has not been developed. According to the main postulates of the integrated approach, hybrid water systems can offer potentially more sustainable solutions than traditional centralized systems. This paper discusses the development process of a decision support tool designed to facilitate evaluation of alternatives based on UWS metabolism concept while addressing some typical challenges of hydroinformatics. This decision-making support tool analyses and compares the sustainability performance of alternative decentralized solutions against a baseline conventional approach on a neighbourhood level. The tool uses a set of criteria, adopted by the large group of stakeholders involved in the development process, that are not typically considered in the decision-making process, such as energy savings, greenhouse gas (GHG) emissions, climate change resiliency, chemical use, and nutrient recovery.

Climate change is globally causing more intense meteorological phenomena. Our cities experience increased rainfall intensity, more intense heat waves, and prolonged droughts providing economic, social, health and environmental challenges. Combined with population growth and rapid urbanization, the increasing impact of climate change will make our cities more and more vulnerable, especially to urban flooding. In order to adapt our urban water systems to these challenges, the adoption of newly emerging water management strategies is required. The complexity and scale of this challenge calls for the integration of knowledge from different disciplines and collaborative approaches. The water sensitive cities principles provide guidance for developing new techniques, strategies, policies, and tools to improve the livability, sustainability, and resilience of cities. In this study, the DAnCE4Water modeling approach promoting the development of water sensitive cities was applied to Parma, an Italian town that has faced serious water issues in the last few years. The city, indeed, had to face the consequences of flooding several times, caused by the inadequacy of both the network of open channels and the sewerage network due to the urban expansion and climate change of the last 30 years. Through the model, the efficiency of decentralized technologies, such as green roofs and porous pavement, and their integration with the existing centralized combined sewer system was assessed under a range of urban development scenarios. The obtained results show that the adoption of an integrated approach, including soft engineering hydraulic strategies, consisting in the use of natural and sustainable solutions, can increase resilience to urban flooding. Further, the study shows that there is a critical need for strategic investment in solutions that will deliver long-term sustainable outcomes.

Urban waters represent a crucial component for the enhancement of urban resilience due to their importance in cities. Nature-based solutions (NBS) have emerged as sustainable solutions to contribute to urban resilience in order to meet the challenges of climate change. In order to promote the use of NBS for increasing urban resilience, tools that demonstrate the value of this type of solutions over the long-term are required. A performance assessment system provides an adequate basis for demonstrating this value, as well as for diagnosing the current city situation, selecting and monitoring the implementation of solutions. Regarding NBS management, some assessment approaches have been published, focusing on assessing the effectiveness of NBS in the face of climate change and supporting their design and impact assessment. Nevertheless, an integrated approach to assess the NBS contribution for urban resilience has not been published. This paper presents a comprehensive resilience assessment framework (RAF) to evaluate the NBS contribution for urban resilience, focused on solutions for stormwater management and control. Furthermore, details on stakeholders’ validation, with focus on the metrics’ relevance and applicability to cities, is also presented.

Abstract. In the Netherlands land subsidence is a continuously ongoing process. Consequently, an increasing number of people and economic assets are exposed to subsidence, damage costs are soaring, and flood risk and greenhouse gas emissions are increasing. In some areas tipping points have already been reached, where current land-use can no longer be maintained without considerable costs, underlining the urgency to take action. Together with a consortium consisting of universities, research institutes, governmental agencies, public and private partners we have developed a national, multidisciplinary research programme aiming to develop an integrative approach to achieve feasible, legitimate and sustainable solutions for managing the negative societal effects of land subsidence, connecting fundamental research on subsidence processes to socio-economic impact of subsidence and to governance and legal framework design. The program is designed to co-create insights that help to effectively mitigate and adapt to subsidence within the Netherlands by making major improvements in measuring and modeling the processes and consequences of subsidence, identifying, developing and critically evaluating control measures and designing governance and legal approaches that facilitate their implementation. Hereto we will develop (a) new satellite-based technology to measure, attribute and monitor subsidence, (b) solid understanding of the interacting multiple processes contributing to total subsidence, (c) sophisticated physical and economic numerical models to predict human-induced subsidence rates and impacts, and (d) implementation strategies that go beyond technical measures, to strengthen governance and financing capacities as well as legal frameworks. This fully integrated approach deals with all impacts of land subsidence on society and the economy.

Two producing reservoirs (H10 and E40) in Eni field Offshore Niger Delta were studied with intent to enhance their rate of recovery while mitigating water production. The material Balance software MBAL was used to estimate the Stock tank oil reserves and then compared to reserve estimates determined by both deterministic and stochastic techniques for improved validation. The MBAL model was also used to identify positions of fluid contacts and determine predominant drive mechanisms. These serve as guide in making informed decisions towards if and how best to economically produce remaining unproduced oil in place. Input parameters were average values derived from core and well logs analyses. History matching of historical data enabled forecasts of possible future production life and volume at multiple scenarios. Final outcomes show that after sixteen and forty five years of continuous  production from the reservoirs studied (H10 and E40, respectively), remaining unproduced oil in place are still significant and can be economically produced by infill wells, which will in return increase the average production by nothing less than 33% of remaining oil in place, a substantial value bearing in mind the growing demand for oil, gas  and other energy sources to lessen the apparently unquenchable world energy needs.

Indonesian Micro Small Medium Enterprises (MSMEs) is a major contributor to the socio-economic development that faces challenges with its sustainability in the current and future market. As a majority of total enterprises in Indonesia, MSMEs has contributed significantly to interconnecting local community empowerment with local economic and business development, resulting in various outcomes for both the business and the community. This research demonstrates that there are still gaps in our knowledge concerning the interaction of creative processes in daily MSMEs business, and in understanding how MSMEs’ creative production can be harnessed to add value and grow their potential for increasing competitive advantage alongside benefits to social welfare. This paper argues that a new approach is needed to support the sustainability of Indonesian MSMEs during the design development process, one that supports and facilitates innovative practice.The study explores how principles in creative process and social life found to be essential to innovation in MSME sector could be integrated within the MSME production cycle holistically using a newly proposed Compassionate Design approach. The new model serves as an overarching framework for establishing and fostering dynamic collaboration among key stakeholder groups and offers a holistic integrated approach of new model be engaged in future direction of local businesses and market opportunities.
