This paper focuses on the valuation of refurbishment costs for healthcare facilities. The determination of the more reliable approach for experimental verification is a research topic of great interest, especially because previous literature on the matter is limited. This study examines ex-ante cost valuations in the refurbishment of healthcare buildings while using similarity to estimate the costs that are based on the amount of already accomplished renovations. The methodology involved a desk analysis deter-mining the technical valuation of intervention needs, and similarity coefficient applications providing a refurbishment cost valuation. The application was conducted in the Friuli—Venezia Giulia Region in Italy, where hospitals show structural, layout, and plants deficits with respect to current regulations, and a technical deepening to identify critical issues is required to prepare a multi-year intervention plan. The case study results showed that this procedure requires little initial information to run analyses and its application can support investment budget planning purposes.

The Impact

One of the goals of any oil terminal is to make a business while avoiding hazardous events and harmful effects for both humans and the environment. This can be achieved by creating a safe working place as well as by performing safe and acceptable activities regarding the impact on surrounding objects, including residential and industrial areas. The aim of the hazard analysis of the oil terminal is to assess the risks related to hazardous events or phenomena and to evaluate whether the assessed risks are acceptable. The hazard analysis and assessment of risk are also used for risk reduction while examining and limiting hazardous scenarios that, for instance, involve the loss-of-containment of flammable or combustible material. In this paper, the authors aim to contribute to risk research by providing a comprehensive methodology of risk assessment for oil terminals with case study results and discussion on features of the methodology, risk aggregation, its applicability for risk reduction, and industrial interests. The performed study considered the “Klaipedos Nafta AB” (an operator of the Klaipeda Oil Terminal, Lithuania) case study regarding hazardous materials that might be released from various tanks, devices, and associated pipelines. The performed quantitative risk assessment has enabled the determination of the probability regarding whether releases would ignite and, for instance, cause explosion. In the case study, the estimate of probability, i.e., the frequency, and the possible consequences of the hazardous events were evaluated, and both mitigation and risk reduction measures were also considered.

Evaluation Techniques

The Contingent Valuation Method (CVM) can be a useful tool for the ex ante evaluation of service innovations in the forestry sector, in particular for transforming a recreational forest function from a free to a payment-based utilisation. In presenting the case study results, the superiority of CVM to other evaluation techniques is discussed.

One hundred and thirty three quake lakes were formed in Wenchuan Earthquake of May 12. There may be several or even a dozen quake lakes in the same drainage basin. During the emergency treatment of quake lakes, due to constraints of resources and time, it is often imperative to select one or a few quake lakes of high priority in the same drainage basin for treatment in order for the entire drainage basin to safely pass the flood season. There are many factors involved in the optimization of emergency treatment project of quake lakes and these factors are usually of different nature. This article proposes to use a multi-level, multi-factor optimization method in decision making of emergency treatment of quake lakes based on the concept and operation properties of fuzzy-consistent matrix. This method is convenient and practical when many qualitative factors are involved and the determination of membership function is difficult. A case study was conducted for the 16 quake lakes on the Mianyuan River by using the proposed method. Three quake lakes selected according to case study results went through emergency treatment before the 2009 flood season, helping the entire Mianyuan River safely pass the 2009 flood season.

<p>Uniform indications for electric consumers classifying are determined according to their technological signs and the physical forms of electrical energy conversion. Levels of consumption in electrical consumers are defined, on the basis of which 29 indexes for investigation, evaluation and comparison of the energy efficiency in electric drives are systematized. The indexes are distributed into 6 groups. Dependencies are defined and methods are developed for determination of the indexes system. An aggregate mathematical model for monitoring and evaluating the energy efficiency of grouped electric drives is synthesized. Case-study results for a typical belt-conveyor system in a thermo-electric power plant are obtained.</p>

Total Fraction

A novel method was developed for the determination of linting propensity of paper based on printing with an IGT printability tester and image analysis of the printed strips. On average, the total fraction of the surface removed as lint during printing is 0.01%-0.1%. This value is lower than those reported in most laboratory printing tests, and more representative of commercial offset printing applications. Newsprint paper produced on a roll/blade former machine was evaluated for linting propensity using the novel method and also printed on a commercial coldset offset press. Laboratory and commercial printing results matched well, showing that linting was higher for the bottom side of paper than for the top side, and that linting could be reduced on both sides by application of a dry-strength additive. In a second case study, varying wet-end conditions were used on a hybrid former machine to produce four paper reels, with the goal of matching the low linting propensity of the paper produced on a machine with gap former configuration. We found that the retention program, by improving fiber fines retention, substantially reduced the linting propensity of the paper produced on the hybrid former machine. The papers were also printed on a commercial coldset offset press. An excellent correlation was found between the total lint area removed from the bottom side of the paper samples during laboratory printing and lint collected on halftone areas of the first upper printing unit after 45000 copies. Finally, the method was applied to determine the linting propensity of highly filled supercalendered paper produced on a hybrid former machine. In this case, the linting propensity of the bottom side of paper correlated with its ash content.

The paper deals with the issues related to the pollution of aquatic ecosystems. The influence of turbulence on the transport and dispersion of pollutants in the mentioned systems, as well as the calculation of the turbulent diffusion coefficients are studied. A case study on the determination of turbulent diffusion coefficients for some sectors of the Prut River is presented. A new method is proposed for the determination of the turbulent diffusion coefficients in the pollutant transport equation for specific sectors of a river, according to the associated number of P�clet, calculated for each specific area: the left bank, the right bank and the middle of the river.
