Environmental Management Systems (EMS) defining a list of requirements that can help organizations to improve their environmental performance. The most common well-known standards are ISO 14001 and EMAS, which both are in a voluntary base. Beside the National Legislation in Cyprus (N.761/2001) there is no any relief document that introduced EMAS Regulation (EC) N. 1221/2009. However, there is an increasing pressure on firms, from a number of different sources (i.e. global market requirements, legislative indirect pressure, customer’s satisfaction etc.), to engage in environmental management initiatives. The aim of this study is to evaluate the incentives as well as the difficulties that Small Medium Enterprises (SMEs) which are located in Cyprus and other European countries (i.e. Italy, Chez Republic and Slovenia) that are facing during the implementation of EMS. The preliminary results indicated that in the case of Cyprus, there are not any specific regulatory reliefs besides some funding programs to convince SMEs to implement and maintain EMAS as well as ISO 14001. On the other hand, in several EU countries there are some more solids measures to encourage SMEs to adopt EMAS.
环境管理体系(EMS)定义了一系列帮助组织改进其环境绩效的要求。最常见的知名标准是ISO 14001和EMAS，这两个标准都是自愿性的。除了塞浦路斯国家立法(N.761/2001)外，没有任何救济文件引入EMAS法规(EC) N. 1221/2009。然而，来自许多不同来源(即全球市场需求、立法间接压力、顾客满意度等)的企业越来越大的压力促使它们采取环境管理措施。本研究的目的是评估塞浦路斯和其他欧洲国家(即意大利、捷克共和国和斯洛文尼亚)的中小型企业(SMEs)在实施环境管理体系期间所面临的激励措施和困难。初步结果表明，在塞浦路斯的情况下，除了一些资助计划来说服中小企业实施和维护EMAS以及ISO 14001之外，没有任何具体的监管救济。另一方面，在一些欧盟国家，有一些更坚实的措施来鼓励中小企业采用EMAS。

The concept of utilizing networks of roads and highways for generating electricity has recently gained considerable attention; advances in the nanotechnology industry offer new opportunities for large-scale improvements in energy efficiency and energy production. In this field, Piezoelectric (PZ) energy harvesting technology has significant advantages over other renewable energy sources such as solar, wind, and geothermal. For example, the embedded roadway system produces little to no infrastructural footprint, and its energy generation span, on a busy highway, can continuously produce energy. However, current low-scale PZ manufacturing methods, and the lack of road-integrated PZ R&D, decrease the cost-effectiveness of this technology and may impact the mainstream adoption of piezoelectric systems. The primary objective of this project was to evaluate the technical feasibility of incorporating piezoelectric systems into roadways. The collaborative research team developed a lab-based Roadway Energy Harvesting System (REHS) using construction and piezoelectric (PZ) materials. The scope of the research project included investigation of the energy harvesting method, preparation of equipment and materials, durability tests of PZ materials and fabricating asphalt and concrete sections for structural and electrical testing. Structural and electrical characterization was completed by measuring the voltage generated in the sections, during a loaded wheel test (LWT), using an Asphalt Pavement Analyzer (APA.) Collected data and various plots developed using Matlab® revealed that deformation in asphalt was correlated to the produced electrical signal. The research results indicated that flexible roadway materials can produce more energy than rigid material such as typical concrete and Engineering Cementitious Concrete (ECC). Similarly, since typical concrete produced higher values than ECC, the magnitude of energy may be more related to strength and density than elasticity, especially in rigid material. Currently, the research team is developing a wafer box coupled with the pavement materials using a 3D printer on with CAD design. The results of this research project will contribute to the possibility of self-supporting energygenerating capacity for highways, for roadway sustainability.

This paper presents the redesign of a burner mixing head that used on High Static Gas burner (HSG) product to mix the gas and air mixture before it is ignited. This burner operates in firing range of 60,000-400,000 Btu/hr. The objective of redesigning the burner mixing head is to improve the overall performance of the HSG burner. This design project deals with the mixing head of a powered gas burner utilizing both natural and propane gases. The mixing head’s function in a powered gas burner is to initiate the fuel gas into an air stream. The redesigned burner mixing head increases combustion efficiency by 3% compared to the original burner head. This new burner mixing head operates within a wider range of excess air of 5% on both the lean and rich side while still igniting reliably and keeping the CO levels under 400 ppm. The redesigned burner mixing head design meets all the criteria of the American National Standards Institute ANSI Z21.17 standard for domestic gas conversion burners. The redesigned burner mixing head was machined out of 304 stainless steel which makes the burner head have corrosion resistant properties this includes using corrosion resistant fasteners.

We present high resolution wind power statistical models fitted to meteorological data for the island of Ireland. We find that a discrete Burr model efficiently represents the number of consecutive hours of wind power availability. Burr models are also useful to model the complement of the wind power availability events, wind droughts, when wind speed is insufficient to produce wind power. The models developed in this study may be most useful at time resolutions less than 6 hours to capture zero power and short bursts of wind power potential. They could serve as a useful complement to other wind power modelling approaches such as MERRA reanalysis models. Wind power duration models, and their wind drought complements, also provide insights for investors on potential wind power availability at geographic locations.

In this work, the effects of various factors such as the aqueous phase pH, the temperature, the ionic strength, the flow velocity and the electrolyte cation nature on the retention, the mobility and the release of Methylene Blue (MB) through quartz sand (QS), used as porous medium, were investigated. Thus, step-input column experiments were carried out to study the transport, sorption and the desorption mechanisms of the MB molecules through a porous medium made of quartz grains. Hence, the five main parameters related to the adsorption experimental conditions, were varied in order to elucidate the adsorption-desorption mechanisms of MB through the QS medium. The MB adsorbed amount, Qads, was found to decrease by decreasing either the pH, in the range 9.5-4, or the temperature, in the range 333-293°K. Similar decrease of Qads was also obtained by increasing the flow rate, Q, in the range 45-90 ml. h-1, or by increasing the affinity of the divalent cation (Ca2+, Cu2+, Zn2+ and Ba2+) toward the QS surface. However, slight decrease in the MB adsorbed amount, was observed by increasing the ionic strength, in the range 10-3-10-1M. The overall data indicate that, electrostatic interaction forces, which occur between the cationic organic pollutant and the negative surface of the quartz substrate, mainly control the adsorption process. In addition, the increase of the adsorbed amount with the temperature, suggests that the adsorption is endothermic in nature.
