The Hideouts of the Vaccination Process

The purpose of the study is to evaluate the degree of information and the population opinion regarding the vaccination process. The paper aims to evaluate both the reasons of decreasing the vaccination degree and the sources of wrong information on this topic to better identify between mistakes and correct knowledge.Vaccines are biological products prepared following specifical tehcniques to improve the body's immunity against particula, given conditions. The lives of millions of children from 188 countries who received different vaccines (diptero-tetanus-pertussis, measles, polio) were saved in the world along the time (WHO, 2017). In Romania, the antidifteric vaccination introduced in 1960 made disappear the disease in 1990. No case of diphtheria has been confirmed so far.Unfortunately, in 2016, the vaccine coverage has fallen below 90% (CNSCBT, 2017) because of either parents' refusal and the failure in attending a family doctor.Therefore, today, the society is facing a serious situation caused by: a) insufficient and erroneous information of parents expressing their opposition to vaccination and b) manipulation of organizations against vaccination

Groundwater quality monitoring study in the west region of Romania

In the present study it was investigated the groundwater quality and its suitability for drinking purposes in several urban and rural areas from Timis, Arad and Bihor counties (West Region of Romania). We have established general and specific techniques for the analytical investigation of the inorganic and organic matrix in the environmental components of water from underground sources, for the identification and quantification of persistent pollutants with toxic potential, especially considering the presence of chlorobenzenes and organo-chlorinated pesticides, organophosphorus pesticides, plant treatment agents (triazine pesticides), benzene and benzene derivatives, polycyclic aromatic hydrocarbons and toxic metals, specifically tracking the presence of arsenic in groundwater resources in the Western Region of Romania

Environmental friendly flocculants for drinking water treatment

Coagulation-flocculation is an important step for the treatment of drinking water obtained from surface water sources. Various types of flocculants are available in the drinking water treatment market but only some of them are friendly for the environment due to their specific structure, which includes natural compounds. Starch-based flocculants are included in this category and some types of them were tested in our research work, in similar conditions with ordinary polyelectrolytes, in order to prove their efficiencies for turbidity and organic load (COD-Mn) removal. Five types of flocculants based on starch and acrylamide were tested during the classic treatment flow coagulation-flocculation-settling with aluminum sulfate as coagulant (1-10 mg Al/L) and 0.5-10 mL/L flocculant dose (0.2% active substance). Better removal efficiencies of turbidity and organic load (COD-Mn) in case of flocculants based on starch and acrylamide copolymers: over 99% for turbidity and ~90% for COD-Mn in case of 300-400 NTU initial surface water turbidity were registered

Romania\u27s Participation to the European Assessment Project Titled HyUnder, Multi-Criterial Analyses of Salt Cavern Locations

The scope of the work is to assess the potential, the actors and relevant business cases for large scale storage of renewable electricity by hydrogen underground storage in Romania. This presentation intends to provide a picture of the multi-criterial analyses of salt cavern locations in Romania. The energy sector is facing with the necessity to store large energy quantities for short to long term in order to adapt to the increasingly intermittent renewable energy. The results of this presentation have originated from an ongoing European assessment project by the name of HyUnder (FCH JU, grant 303417) regarding utilization of salt caverns for hydrogen underground storage. Currently, main uses of salt caverns include storage of hydrocarbons or wastes disposal. Salt caverns have stirred the interest of the scientific community regarding the potential applications in hydrogen economy. Romania has active mines or caverns and others closed, many of them have the potential to be used from hydrogen storage. These facts represent an interested situation in order to initiate studies or assessments of the potential hydrogen underground storage. The salt mines, hydrogen producers, renewable energy sources and research centers with high qualified scientists, represent essentially elements for new type of studies regarding hydrogen economy. In the context of scientific community\u27s efforts from Romania to assert active in the area of hydrogen technologies, this approach can certainly constitutes an attractive example for pan-European cooperation. The work disclaims the technic multi-criterial analyses of salt cavern locations regarding hydrogen underground storage. The introduction of hydrogen into economy offers the possibility to provide a number of advantages: sustainable development, valorization of local resources and improvement of competitiveness. The opportunities and viabilities of salt cavern locations are analyzed
