Nowadays, polluted soils are one of the primary environmental problems. Due to a large number of oil-contaminated lands, new methods are being developed more and more actively, as well as a combination of various existing methods for disposing of oil spills. In this paper, bioremediation with the use of adsorption is considered to reduce toxicity and accelerate the processes of microbial destruction of hydrocarbons. There is a large selection of sorbents based on carbon, mineral, and natural materials. The effectiveness of a particular sorbent will vary depending on the application region, weather and climate conditions, soil type, and the type and properties of the oil. In this work, peat was tested as an organic sorbent (S1), vermiculite as a mineral sorbent (S2), and sorbent based on carbon (S3). The sorbents were added to the soils contaminated by oil, evaluating the pH, humidity, and phytotoxicity of the soils. The results showed that the soils treated with sorbents maintained the neutral pH, increased the humidity, and decreased the phytotoxicity of the soil. The sorbent efficiency was S3> S2> S1.

Today, there is no consensus on the selection method of representative exterior boundary conditions when performing HAM (Heat Air Moisture) simulations on building envelopes. Many existing methods to select moisture reference years (MRY) fail to provide an acceptable validation in terms of quantified risk assessment. Although new methods have been suggested during the past few years, the influence of several parameters on the selection of “critical years” in long-term datasets still needs to be assessed. The objective of this paper is to validate the application of MRY’s to evaluate freeze-thaw risk in retrofitted solid masonry. Furthermore, the influence of the chosen wall assembly, damage criterion, preconditioning and start date of the evaluation period on the ranking of critical years is assessed, using a 31-year meteorological dataset of Brussels. Results indicate that for a given wall assembly and freeze-thaw criterion, as well as a smart start date of the evaluated period, single year simulations entail a similar ranking of critical years as the corresponding year in the 31-year simulation. The number of critical freeze-thaw cycles only varies between 0 - 2 cycles (0 - 2.9%). However, changing the wall assembly and damage criterion, alters the top 5 ranking of critical years substantially.

The need for environmentally compliant processes and materials in the Painting Industry grows more pressing every day. As the need for these processes grows, so grows the confusion regarding the selection and implementation of these new methods and materials. In the past, price and traditional procedure were the only criteria by which a material was procured. Speed and compliance with Original Equipment Manufacturer specification governed how things were done on the shop floor. With the advent of the environmental regulations, processes are being examined all across the globe. In many of the larger companies, the chief environmental officer has as important a role as the comptroller or Chief Financial Officer. Environmental managers are often not chemists or line painters, and typically, the environmental manager is skilled only in the policies of waste disposal, spill clean up, or remediation. The methods whereby a company can minimize the generation of hazardous waste remain less familiar. Often the examination of possible alternate techniques and materials are left for the last minute, or are conducted by personnel who are unfamiliar with how to make changes work. This is usually a recipe for failure in the implementing of anything new. This paper will suggest methods for selection of alternative products and processes in a clear and organized manner. Salient discussion points will be: 1. Process Examination 2. Material Selection 3. Steps For Successful Implementation 4. Possible Impediments 5. How to Avoid Risky Alternatives It will focus on procedures that will assist in the decision making process, and hopefully be of use in the choosing of environmentally sound equipment, chemicals, and methodologies.

Every year, more than 1 million cases of scorpion envenomation are reported worldwide. Scorpions are thermophilic organisms. They are sensitive to weather and climate conditions, in such a way the ongoing trends of increasing temperature and more variable weather could lead to scorpionism spreading. There has been considerable debate as to whether global envenomation will be impacted by climate change which has focused on snake and spider envenomation risk. This debate didn't give enough interest to scorpion stings and its burden risks, in spite their widespread potential effects in many regions. Here, the authors review how climate and climate change may impact scorpion activity as well as scorpion envenomation. They contrast ecological and behavioral characteristics of these arthropods, and how weather, climate, climate change, and socioeconomic factors may have very different impacts on the spatiotemporal occurrence and abundance of scorpions, and the resulting scorpion envenomation.

This article substantiates the selection of a new object in accounting – the cost of Internet technology. The author presents new methods for accounting the costs of Internet technologies and provides the interpretation of the concept of «virtual assets». The author considers it necessary to introduce separate accounts for accounting the costs of Internet technologies. We believe that this approach will allow to see the total amount of the costs of Internet technologies, which is important for purposes of planning, monitoring and analysis, as well as to resolve contentious issues arising in accounting the costs of Internet technologies, which will significantly facilitate the work of accountants. In the absence of theoretical developments in accounting the costs of Internet technologies we make the first attempts to classify the costs of Internet technologies. We propose grouping the costs according to the following criteria: their purpose; frequency of occurrence (one-time and ongoing); gains in the time period (current, deferred costs and capital). The author concludes with a recommended register for accounting the costs of Internet technologies.

The issue of climate change is undeniably demonstrating its presence. Consequently, there is a rising need to be prepared for upcoming threats by any means possible. One of the precautions includes obtaining the information characterizing the expected impact of global warming. This will allow authorities and other stakeholders to act accordingly in time. The article presents the assessment of the extent of impact of energy-related construction solutions in dwelling type unit situated in Central Europe region under the 21st century climate conditions. The findings represent eventual demands of energy for cooling and heating and its prospective savings. This is conducted by consecutively and automatically changing the parameters in individual simulation runs. As a basis for simulations, regionally scaled weather data of three different climate areas are used. These data are based on the emission scenarios by IPCC and are reaching to the year 2100. The selection of assessed parameters and climate data application are briefly explained in the article. The results of simulations are evaluated and recommended solutions are stated in regard to the specific energy-related construction changes. The aim is to successfully mitigate and adapt to the climate change phenomenon.

The rational use of energy has motivated research on improving the energy efficiency of buildings, which are responsible for a large share of world consumption. A strategy to achieve this goal is the application of optimized thermal insulation on a building envelope to avoid thermal exchanges with the external environment, reducing the use of heating, ventilation and air-conditioning (HVAC) systems. In order to contribute to the best choice of insulation applied to an industrial shed roof, this study aims to provide an optimization tool to assist this process. Beyond the thermal comfort and cost of the insulation, some hygrothermic properties also have been analysed to obtain the best insulation option. To implement this optimization technique, several thermo-energetic simulations of an industrial shed were performed using the Domus software, applying 4 types of insulation material (polyurethane, expanded polystyrene, rockwool and glass wool) on the roof. Ten thicknesses ranging from 0.5 cm to 5 cm were considered, with the purpose of obtaining different thermal comfort indexes (PPD, predicted percentage dissatisfied). Posteriorly, the best insulation ranking has been obtained from the weights assigned to the parameters in the objective function, using the technique of the genetic algorithm (GA) applied to multi-criteria selection. The optimization results showed that polyurethane (PU) insulation, applied with a thickness of 1 cm was the best option for the roof, considering the building functional parameters, occupant metabolic activity, clothing insulation and climate conditions. On the other hand, when the Brazilian standard was utilized, rock wool (2 cm) was considered the best choice.
