Future climate scenarios of the Global Circulation model (GCM) show an increased frequency of heavy rainfall events, which may lead to more severe floods. It is also expected that more and more areas will suffer due to flooding as a result of growing urbanization. Public attention has increased in many parts of the world in recent years and calls have been made to improve flood warnings, including the United States, the European Union and Australia (Hapuarachchi, H.A.P, and Q.J. Wang 2008). To respond and manage f...

Taxation can be used as a tool to promote sustainable waste management and recycling of industrial plastic, paper and glass; therefore, this article aims to assess the effectiveness of existing waste taxes by considering their effects on waste generation and disposal in Europe. In this context, a comparative study has been carried out to understand taxpayers- behaviours towards waste taxation, tax rates and methods preferred to calculate the amount of tax to be paid. Sustainable waste management is of particular i...

A miniaturized on-board platform for optic sensors stabilization is the proposed concept developed and tested by a multidisciplinary team of engineers under a UEFISCDI (the Executive Agency for Higher Education, Research, Development and Innovation Funding in Romania) research funding. The need for a UAV to capture images and give in-depth information of ground objects is fulfilled by the developed three-axial stabilized optical system. Modern techniques, technologies and state-of-the-art electronics are employed ...

Organic waste has been discharged into the environment by various industries in a global society. Anaerobic digestion has proven its potential as a waste-to-energy (WTE) technology to produce biogas, which can also replace fossil fuels while accommodating these unwanted wastes. However, there are limitations to anaerobic digestion, such as poor biomethane yield due to limited supply and fluctuations in the composition of the substrates, and an inadequate C/N ratio in the feedstocks. This paper aims to discuss poss...

The aim of this study is to present preliminary results of testing the new non-hydrostatic dynamic core of the regional climate model RegCM4.7.1 by varying different parametrization schemes over the Balkan Peninsula and Bulgaria. A one-way double nesting technique was applied, employing a mother domain with 15 km grid spacing and a nested domain with 3 km grid spacing. Twenty test simulations were performed with a model resolution of 15 km for the year 2000 on a Lambert Conformal Conic projection and 12 test simul...

In addition to its main purpose: establishing and maintaining the parameters of the height system for the territory of a given state (country), state levelling networks also serve to establish (register) the contemporary (recent) vertical movements of the Earth's crust. The detection of such movements, besides in a purely research sense, is of great practical importance. The displacement of the benchmarks over time plays an essential role in seismic forecasting in the short and long term. Sometimes, not very often...

Mining wastes represent a specific type of waste and, like sites after mining, represent sites where a comprehensive assessment of pollution at these sites needs to be approached, taking into account various specific conditions. Subsequently, the design of the remediation technologies used at a specific location must also be adapted to this fact. Until now, mining waste facilities (heaps and sludge ponds) have been treated as environmental burdens. However, it should be borne in mind that abandoned extractive wast...

Genomes of alfalfa root nodule bacteria, Sinorhizobium meliloti, symbionts of alfalfa are enriched in non-symbiotic (cryptic) plasmids, which gene pool is remained weakly studied. S. meliloti strains are significantly varied in number and size of these plasmids. The goal of the study was to assess the occurrence of phage-related sequences (PRS) on cryptic plasmids. Whole genome sequences of 12 S. meliloti strains native to Caucasian and Kazakhstan centers of alfalfa diversity (NCG and PAG, correspondingly) were st...

The problem of academic perfectionism in teaching technical English at a higher education institution stems from a number of external and internal factors - the current educational targets set by managing social groups and student ambitions. The research methods included the analysis of objectives, contents and teaching methods intended for the first and second year bachelor degree students. The findings show that the target competence, being focused on the technical English, also incorporates the ability to solve...

The presence of nitrate concentration in drinking water can cause high toxicity to the human body, being considered among the most important pollutant in the environment. Among the many methods available such as biological treatment, electrodialysis, reverse osmosis, adsorption, ion exchange, adsorption is the most used technique due to its low cost and simplistic design. Therefore, the aim of this paper was to study the retention of nitrate anion from high concentration aqueous solutions on a novel magnetic adsor...
