Laetiporus sulphureus (Bull.) Murrill is an edible wood-rotting Basidiomycete widely consumed as a nutritional food. These mushrooms were found to be medically active in some therapies, such as: antimicrobial, antitumor, antiviral, and immunomodulating treatments. In this work, antioxidant and antimicrobial potentials of L. sulphureus alcoholic extracts from dried fruiting bodies, dried mycelia broth and mycelia-free broth submerged cultures were investigated. For determination of potential antioxidant activity of thedried fruiting bodies and mycelia-free broth methanol extracts, the total phenols amount and scavenging capacity on 2.2-diphenyl-1-picrylhydrazyl (DPPH) radicals have been analyzed. The results showed that the highest total phenols amount (283.9 mg GAE/100g) was found in fruiting bodies extract. Radical scavenging activity was found higher for fruiting bodies extract (EC50=35.45 mg/ml) followed by mycelia-free broth extract (EC50=46.67 mg/ml). The antimicrobial effects of the ethanol extracts were analyzed against Candida albicans ATCC10321, Candida parapsilopsis CBS604, Escherichia coli ATCC8739, Staphylococcus aureus ATCC6538, Enterococcus faecalis and Staphylococcus epidermidis ATCC12228. Two extracts presented a wide antimicrobial spectrum and were active against both yeast and bacteria tested: fruit bodies extract and dried biomass extract.

Plantago lanceolata L. is used as astringent, anti-inflammatory, immunoregulatory, antispasmodic, expectorant, emollient, topical anodyne, antibacterial for cuts, bruises and abscesses. These pharmacological properties are due to its complex chemical composition: iridoid glycosides, polysaccharides (plantaglucide, glucomannon), terpenoids, coumarins, lignans, caffeic acid derivatives, polysaccharides, flavonoids, flavone glycosides and other constituents, like allantoin. In this paper, antioxidant activity, qualitative and quantitative determination of some active components (flavonoids, polyphenols, and polyphenols carboxylic acids) are evaluated, taking into account the biological properties. Antioxidant properties were evaluated by chemiluminescence (CL) technique in system generator based at 5-amino-2.3-dihydrophthalazine-1.4-dione and hydrogen peroxide, in alkaline medium and DPPH (2.2-diphenyl-1-picrylhydrazyl) method. The total flavonoids, polyphenols content and polyphenol carboxylic acids was spectrophotometrically determined according to Romanian Pharmacopoeia (FR). In addition, the qualitative biochemical fingerprint was investigated by mass spectrometry LC-ESI-MS. The mass spectral data and amount of active components (flavonoids, polyphenols, polyphenols carboxylic acids) demonstrated the chemical structural complexity. The results of the chemiluminescence in vitro tests revealed that the Plantago lanceolata L. extracts exhibit high antioxidant activity (84-96%), being in accordance with the value provided by DPPH free radical scavenging assay. Also is established a dependence directly proportional to the content of polyphenolic compounds found in herbal extracts with level of antioxidant activity.

Various studies have shown that the wine consumption decline in young generation could be influenced by the perception of wine as intimidating and difficult to understand, and by the lack of adaptability of the product’s communication strategy and packaging design to their lifestyle. Information available on the packaging is often complex and confusing for novice wine consumers and sometimes even irrelevant in regards to the intrinsic characteristics of the product. Furthermore, wine is seen by young adult consumers as old fashion, formal and mostly not associated with their relaxed attitude and “on the move” lifestyle. The objective of this paper is to analyse the usability key principles and heuristic and their applicability in wine marketing as a mean to improve the perception and increase understanding of wine for the young and/or novice consumers. The paper aims to review the existing knowledge and findings about the concept of usability (with special emphasis on Usability Engineering and Human Computer Interaction (HCI)), in order to explore the aspects applicable in wine marketing. The usability concept proves useful in wine marketing to simplify the decision process, to make the meeting with the product less intimidating and more engaging, and to decrease the risk perception for the inexperienced wine consumers.

Quantitative estimation of water resources is indispensable when it comes to getting the sustainability of aquifers through planning. This becomes an essential aspect in areas whose primary economic activity is agriculture, in which ensure the availability of water means ensuring the sustainability of the societal and economic systems. This is the example of the Cuellar Moor karstic aquifer, located in the international Duero watershed, in which more than 80% of its surface is aimed to agricultural use. The main goal of this research is the introduction of a new vulnerability index, which gathers together the hydrogeological covariates and the spatial uncertainty associated with the estimation of groundwater level and nitrate concentration. An optimized monitoring network to piezometric level and nitrate concentration control is required, as well as, to determine the vulnerability associated with pumping wells.

This paper tries to present the concentration dynamic of the principal quality indicators of the groundwater from Balesti-Tamasesti perimeter, Gorj County, in the last 45 years, in a special geographical area - with groundwater very closed to the land surface, making them very vulnerable to anthropic pollution, the area being declared under common Order of MESD and MARD no 1.552/03.12.2008/743/12.12.2008 as an area included on the list of localities with nitrates sources from agricultural activities. The characterization of the groundwater quality from the studied perimeter was based on the physico-chemical analysis bulletins of hydro geological drillings from the national network of groundwater monitoring, from their execution (period 1970-1974), from these in the studied perimeter being part the hydro geological stations, as well as the citizens wells (2013-2015); the monitored wells have been chosen on the flow direction of groundwaters established by original hydro geologic map and hydro geologic section, elaborated through Sub Carpathian hillock depression. According to the report on the implementation of the Nitrates Directive published by the European Commission, Southern Romania is among the areas in the EU where groundwater contain elevated levels of nitrates, due to use of chemical fertilizers and organic nitrates, as a major source of water pollution. In all 27 Member States is a decrease in the quantities of nitrate in water, so that the implementation of legislation designed to prevent pollution of land and water with nitrates from agriculture became a success. Following the conducted monitoring in Gorj area - Romania, we observed a significant appreciation of quality indicators of groundwater, sowe could recommend implementation of measures to protect and continuing rehabilitating groundwater quality in Baleşti by building some sewage-evacuation-disposal plants, because the quality of groundwater here could return to further nitrogen compound concentration values existing in the natural background of groundwater.

Considering the development and computerization of cadastre in Europe and the importance they have land registers and real estate records in Romania, which is a member country of the European Union, and in the future will have to develop the information society and cadastre will be the main territorial database. This paper, regarding the informational system specific for real estate domain of Sărmaşu, Mureş County, is a step toward developing computerized urban and rural localities in Romania. Spatial data are taken from the cadastral plan of the city. Creating a database is to determine: the study area, the coordinate system used, the layers necessary for studying the elements (geographical objects) included in each layer, the attributes necessary for the description of each item type, the method of coding and organizing the attributes. The creation of the database was performed in three steps: i) identifying graphical objects and their attributes and organize layers; ii) defining attributes; iii) ensuring records coordinates between layers. The advantages of using a Geographic Information System over traditional methods are numerous: improving service quality, optimizing circuit information between organizations, producing interactive maps, the ability to produce standardized maps, avoiding duplicate data maintenance banks.

The aim of this study was to comparatively analyze the impact of dairy farming policies on the socio-economic and technological characterization of dairy industry. Primary data were collected from dairy farms through the use of structured questionnaires and were analyzed using both descriptive and inferential statistics. Data obtained was analyzed using Chi-square (χ2) test. In this study, modern and traditional dairy farms were compared in terms of their socio-economic and technological characterization and structural farming practices, and adoption levels of dairy farming support services. The results revealed that there is a statistically significant difference between the improved and traditional dairy farms in terms of education level of farm holder, gender of farm holder, agricultural credit use, purpose of dairy farming, farm land size, number of cattle, number of milking cow, barn type, size of barn, feeding system silage making status of farm, fodder crop growing, milk marketing channels, farmers’ reasons for choice in milk marketing channel, type of dairy farming supports received by farmers, use purpose of dairy farming supports by farmers, effects on modernization of dairy farms and increase in farm income of dairy farming supports variables. The result depicted that improved dairy farms benefit more from dairy farming and rural development supports than the traditional dairy farms. As dairying is the sole source of income in the area, the study concludes by highlighting the importance of government support for small and medium sized dairy farms in the study area. The conclusion is that policy makers should take into account socio-economic and technological characterization of dairy farms in implementation of dairy farming policies to ensure sustainable food security, food safety and farmers’ income.

Soils pollution with crude oil is becoming an ever increasing problem, especially in the light of several breakdowns of oil pipelines and wells reported recently. Due to its toxicity, widespread presence and complex nature, this type of pollution is a serious problem, one reason being that as the modern civilisation, urbanisation and mechanisation develop the use of crude oil products grow. The influence of soil pollution with crude oil depended on the type of soil, crude oil concentration in soil and fertilisation. The study has been undertaken to assay the biodegradation yield of soil polluted with crude oil and treated in different experimental variants. In soil polluted with 5% crude oil, doubling fertiliser dose from 0.25% to 0.5% has exercised the most spectacular effect, causing an increase of yield to 45.7% in absence of bacterial inoculation. Atlow fertiliser dose, inoculation with selected bacteria induced a strong stimulation effect; the bioremediation yield is 24% higher thant hat determined inuninoculated variant. In variants excessively polluted with 10% crude oil, microorganisms with biodegradation capacity of petroleum hydrocarbons have required amore or less period of time to adapt to pollutant presence in excess. Necessary period to adapt to environmental changing, microorganisms was significantly decreased by soil conditioning with Ecosol at 1% concentration.
