Abstract The article presents a way of remodeling old building facades, which have been subject to degradation, with the help of common software. There are two methods of reconstruction presented: the first method is using the Adobe Photoshop software and the second method is using the Agisoft PhotoScan software. A comparative study is presented, by showing the advantages and disadvantages of methods, as well as their similarities and differences. The building that is the subject of the study is one of the oldest buildings belonging to the university. It is noted that by combining modern technology (aerial scanning) and common software solutions, there can be found a fast and reliable response to the need for restoration and conservation of historical buildings.

Abstract The aims of this work were to determine which storage conditions can preserve the quince quality (Cydonia oblonga Miller, Rosaceae family), stored in three different rooms with controlled atmosphere (CA). Due to their reported high polyphenolic content in the fruit, three varieties of quinces, like Ekmek, Bereczhi and Tinella were stored and monitored for twelve months. During storage period, the following quality parameters were monitored: dry matter content (D.M.%), titratable acidity (TA), soluble solids (°Brix), firmness, antioxidant capacity and also content in total flavonoids and total polyphenols. After twelve months of storage, observations showed that quince from Tinella variety presented better quality parameters compared to quinces from Ekmek and Bereczhi varieties. As expected, keeping quinces in the presence of CO2content, respectively 2% and 5%, presented better physical and biochemical quality compared with those stored without CO2 (control).

Abstract Twenty-three new Romanian table grapes varieties were analysed for their phenological behaviour, quantitative characteristics (bunch weight, berry weight, their length and width, grape yield), sugar accumulation, titratable acidity, and ºBrix / acid ratio during three consecutive years (2015-2017). The higher temperatures recorded during the study period determined an advance in the development of the main phenophases, especially the grapes’ harvest maturity. Absolute minimum temperatures during winter, damaging the vine, have significantly affected grape yield. As a consequence of earlier phenology and lower yields due to frost damage, harvest was advanced between 2 and 4 weeks than the average. The results obtained in this study favoured five remarkable genotypes for their very good quality of grape (‘Victoria’, ‘Tamina’, ‘Xenia’, ‘Napoca’ and ‘Augusta’). These varieties are distinguished by the highest values for bunch and berry weight (between 300-500 g and 5.5-8.4 g, respectively), berries’ size uniformity, the sugar content between 15.45-21.53 ºBrix and balanced ºBrix / acid ratio. Lately, the high temperatures during the grape maturation period have led to increased accumulations of sugar in berries, to reduced acidity, which affects the sugar-acidity balance; a more careful choice of grape harvest time is needed.

Abstract Origanum vulgare L. var. aureum is an aromatic medicinal plant belonging to the Lamiaceae family, rich in essential oils and antioxidants. Its specific chemical composition represents an important source of biologically active principles with diverse applications in food products and nutraceuticals. The aim of this study was to determine the differences between chemical composition of volatile oils, phenolic content and antioxidant activity of different plants parts: leaves, flowers, and stems. Essential oils from leaves and flowers had similar compositions with only few differences between γ-terpinene and trans-ß-ocimene. Total phenolic content and antioxidant activity were determined for the hydro-alcoholic extract obtained from post-distillation oregano waste material. The total phenolic content was determined using Folin-Ciocalteu reagent and varied from 3173 to 6522 mg GAE/L. The major compounds identified by HPLC were syringic acid, pyrocatechol, and catechin. Furthermore, all extracts showed high antioxidant activity, ranging from 31.3 to 44.5 mg GAE/L, with an inhibition percent varying from 63.1 to 88.6%.

Abstract Drought is one of the most significant extreme event facing the world, affecting the society and the environment. Located in SE Romania, Dobrogea Region is characterized by a temperate climate with strong continental influences, being affected by drought episodes which cause significant damages and economic costs over extensive agricultural areas. Risk reduction, continuous vegetation monitoring, and management implementation are facilitated by complementary use of vegetation indices and biophysical parameters derived from satellite products (gridded data) within-situ data (point data). The paper focuses on:i) evaluating the extent and intensity of drought in Dobrogea, Romania, based on Normalized Difference Drought Index (NDDI) and Fraction of Absorbed Photosynthetically Active Radiation (FAPAR); ii) fires analysis, based on the Thermal Anomalies/Fire locations product (MCD14DL); iii)the correlation between the fires with the NDDI; iv) and the correlation between fires with the Land Surface Temperature (LST) product. The vegetation indices, biophysical parameters and fires are computed from Moderate Resolution Imaging Spectroradiometer (MODIS) daily and eight days’ synthesis products, during 22th of March - 29th of August 2000-2015. The results highlight the areas most affected by drought (moderate, severe and extreme) and fires in the Dobrogea.

Abstract Our bibliographic insights have shown that although thermographic imaging in small animals has been poorly studied, the empirical use of thermographic images in dogs suggests that thermographic imaging could be a useful method in assessing walking anomalies. The study aims to identify existing thermal asymmetries between the thermal paw prints of the hind limbs in healthy dogs (right versus left). For thermal investigations, the Flir E50 thermal camera with a resolution of 240×180, thermal sensitivity of 0.05ºC, 45º×34ºA visual field and unbalanced microbolometer was used. Acclimatization of the animals in the space for examination was 30 minutes (at a room temperature of 20-23°C). The resulting images were recorded, processed and analyzed with the Flir tools 2017 software. The average, maximum and minimum temperature of each image was calculated using the program. The results obtained show that between the thermal paws marks of the posterior limbs in healthy dogs there is an average thermal asymmetry comprised between 0.2 and 1.4°C. Our study suggested that, under controlled conditions, thermographic paws prints could be used to diagnose locomotor abnormalities in dogs..

Abstract Hydroponic systems are highly appreciated today, due to their potential to protect the environment and ensure a high level of food safety. In general, aromatic plants play a very important role in the food, pharmacy, cosmetics, perfumery and aromatherapy industries, all these products being highly appreciated by consumers. Due to their importance, different hydroponic systems are put in place to grow at different levels, these aromatic plants. In the present study, is analyzed the influence of three different hydroponic systems (two vertical and one horizontal) on minerals content and nutritional quality of two varieties of Occimum basilicum and one Mentha piperita variety. In this study are presented dry matter content, ash, micro and macro elements and contaminants content of leaves are presented. The results showed that the vertical system without foil had the best results, followed by the vertical system with foil comparative to the horizontal system that had the lowest content in nutritious principles. The vertical eco-sustainable systems proved to be a promising innovation for growing aromatic plants at the household level and a promising start for the intensive growing.

Abstract The present paper addresses an analysis of the economic, touristic and gastronomic evolution of the county starting from the period before the 1990s until 2016. Initially, the economic growth of Alba County started with its industry, especially the chemical, wood processing, machine building, and food industry, but also with mining. Afterwards, there was a period of economic decline, thereafter the industry in this area started to relaunch, however, below the 1990s level. The results of the study show the existence of many tourist attractions with great potential for growth and it also present the economic growth potential of Sebes, Cugir, Blaj, Alba Iulia, Rosia Montana, Zlatna, Ocna Mures, Arieseni and Aiud. The conclusions of the study highlight the need identified at county level, namely the necessity to turn into account the wine route by expanding accommodation capacities, taking advantage of the touristic objectives, developing the infrastructure and tailoring the offers

Abstract Fatty acids represent important substrates for obtaining microbial lipases and biosurfactants. The yeast strain CMGBRG5 was identified as Rhodotorula glutinis using the BIOLOG MicroLog System. The opacity screening tests showed that R. glutinis CMGB-RG5 was able to produce lipases in presence of 1% Tween 80 after three days of incubation. Lipase induction was estimated as cell growth in presence of Tween 80, Tween 20, olive oil and tributyrin. After 48 hours, best results were obtained in presence of butyric acid, respectively, oleic acid: 2.2 × 107 cells/ml on tributyrin and 1.0 × 107 cells/ml on olive oil. Biosurfactant production was evaluated as emulsification index (E24%). After one week, high E24 values were obtained on fried sunflower oil (53%) and olive oil (35%). Crude and concentrated biosurfactants were tested against nine Candida strains. Best antimicrobial activity was observed for [20X] biosurfactants against C. tropicalis, C. guilliermondii and C. krusei. In conclusion, R. glutinis CGB-RG5 shows high potential for using fatty acids from various sources as unique carbon substrates for synthesis of biocompounds with high economic and biotechnological value.
