Flash floods simulation in a small drainage basin using HEC-RAS hydraulic model

Abstract

In recent years, climate conditions has caused extreme hydrological phenomena like flash floods that lead to significant material losses and impact on the environment in Dobrogea Region, Romania. In this context the needs for an integrated and sustainable approach to flash flood risk management even in small drainage basins are necessary, in order to reduce the the potential damages of flash floods in the future. In this study the hydraulic models Hec-Ras and HecGeo-Ras were used in order to simulate the behaviour of the environment at the pressure of the flashfloods in a small drainage basin. The results were validated using the measurements undertaken after the flash-flood event recorded in October, 13th, 2015 as well as the data provided by the Corbu gauging station along time.

Blood-based biomarkers in Alzheimer’s disease: an overview on proteomic and lipidomic approaches

Abstract

Alzheimer’s disease (AD) remains one of the most challenging pathologies since its etiology is not completely known, its progression is slow and there are no disease-changing pharmacological agents available yet. One other important characteristic is that the progression of AD pathology starts long before any symptoms are experienced by patients. This is where the need for early detection biomarkers comes from. Although there are biomarkers that have been intensely studied and are now included in research criteria, most of these biomarkers are either invasive or unaffordable. Blood-based biomarkers could be a viable alternative of accessible and acceptable biomarkers, and have been much studied in the past decade. Among them proteomics and lipidomics seem to be two most promising fields for biomarker development. The paper aims to offer an overview of developments in the field during the past 5 years highlighting the most promising biomarkers.

Localized Irrigation System for Thuja Orientalis in Intensive Culture

Abstract

In order to increase the competitiveness of an agricultural holding through the efficient use of the production factors, the modernization of an agricultural farm was carried out by exending the existing greenhouse with at least 700m2 for the intensive cultivation of ornamental plants - Thuja Orientalis. The material is produced by initiating crops in pots, with seedlings grown in pots or transplanting them in pots right after the first year of the multiplication and growing them in containers, appropriate to their size, until reaching their full value. From a technical point of view, reaching the objective will also be possible through a localized irrigation system.

Reabilitation of a wastewater treatment plant – possible environment impact

Abstract

Romania, has declared, by the Governmental Decision nr.352/2005, all its territory as a sensitive area. This implies that, for all urban agglomerations larger than 10.000 population equivalent waste water treatment plants (WWTP) with nutrient removal must be built or upgraded. This paper presents the results regarding the possible environmental impacts expected from the project for construction of waste water treatment plant in the City of Vaslui, with main focus on surface water. This research study includes assessment methodology, project description regarding the rehabilitation and extension of the Vaslui waste water treatment plant, data related to water resources, impact assessment on water and appropriate mitigation measures. The assessment of the impacts has been performed for the construction and operational phase of the wastewater treatment plant. The construction phase was subdivided into several phases, while in the operational phase the impacts are analyzed following the line for treatment of the wastewater and effluent production, the line for sludge production and drying process, sludge disposal in safety conditions considering the provisions of 86/278/EEC Directive and the line for biogas utilization.
