Abstract World energy systems development is based on the use of renewable sources, their valorisation benefits of technical and economical stimulating actions. The main disadvantage is related to the low efficiency caused by low energy density and high value investments. The cost of renewable energy is higher than energy coming from conventional sources. Reducing the costs of producing unconventional energy can be achieved by integrating economic and social activities into the system, providing futher benefits. From the potential point of view, it is estimated that biomass occupies the first place in a ranking of unconventional energies. Biomass boosted by anaerobic fermentation with biogas production and cogeneration can provide "peak" energy production and can balance energy systems. Waste utilized by these processes involves reducing environmental impacts by diminushing managed volumes and efficient control. In the present paper are characterized by calculations aspects of the exploitation and elements regarding the optimization of some high-capacity fermenters of a wastewater treatment system.

Abstract Rosa canina L. fruit have been used internally as tea for treatment of viral infections and disorders of the kidneys and urinary tract. Also, it was reported that the R. canina fruit, with its high ascorbic acid, phenolics and flavonoids contents, have antioxidant, antimutagenic and anticarcinogenic effects. Antioxidants neutralize free radicals, which cause oxidative damage to lipids, proteins, and nucleic acids and thus protect the organism. Research studies conducted on this topic have shown that natural antioxidants are involved in protection against many diseases: cancer, cardiovascular diseases and osteoporosis. Different processing and storage methods of the fruit could affect the bioactive nutrients while preserving the antioxidant capacity of them is very important. The aim of this study was to evaluate the effect of storage in a dry or frozen state on the antioxidants content of R. canina fruit. The evaluation involved determination of carotenes, ascorbic acid and total polyphenols using spectrophotometrically methods. Analysis performed on the R. canina fruit showed significant changes in the antioxidants content in fresh, dried and frozen fruit during storage.

Abstract The aim of this study is the comparative investigation of spectrographic carbon electrode’s viability as working electrode, in ascorbic acid and sulphite asssessment. Cyclic voltammetry involves a linear sweeping of the potential, the analytical signal being represented by the anodic oxidation /cathodic reduction peak of the analyte. For both analytes, the electro-oxidation resulted in an anodic peak, correlable with ascorbic acid / sulphite concentration. The analytical range of linear response corresponded to 0.07 - 10 mM for ascorbic acid and to 15.5 mg/L - 4 g/L for sulphite. The relative standard deviation RSD (%) was 2.71 % for ascorbic acid and 2.88 % for sulphite. The sensitivities, given by the slopes of the calibration graphs were 88.88 μA/mmole/L for ascorbic acid and 477.37 μA/g/L for sulphite.

Abstract Natural by-products from vegetable oil industries and spent edible oils from domestic or public food spaces should be recycled to obtain new added value products. Present paper proposed a technical solution for complete valorisation of inedible oilseeds or spent edible oils into bioproducts for nutrition and protection of plants cultivated in conservative organic agrosystems. Pressed cakes resulted from mechanical cold extraction of mustard oil contain residual oil and bioactive compounds which were released using an enzymatic cocktail 1:1 cellulase with proteases coupled with azeotropic solvents into a single Soxhlet extractor. From mustard meal, a solid fraction with glycerol derivatives of fatty acids (56.23% oleate and 17.47% linoleate) decanted from syrup (41.78% xylopyranoside and 48.48% trilinolein) and from mustard cake (76.44% linoleate) in the supernatant, the same oligosaccharide (29.64%) and proteinates (30.18%) in the solid fraction. The total extract was simultaneously concentrated and converted into a bioactive potassium salt emulsion able to encapsulate insectofungicidal natural compounds as bioproducts with agronomical applications.

Abstract The purpose of this paper was to compare the composition (weight % of total identified FA) in saturated (SFA), monounsaturated (MUFA) and polyunsaturated (PUFA) fatty acids from 3 food matrices (sunflower oil, palm oil and lard) by 2 different techniques, gas chromatography - mass spectrometry (GC-MS) and nuclear magnetic resonance (NMR). For GC-MS technique, fatty acid methyl esters (FAMEs) identification in the samples was performed by comparison of the retention times (RT) and the mass/charge (m/z) ratio characteristic of each FAME component in the reference standards used (F.A.M.E. Mix C4 - C24 and SRM®2377). FAMEs quantification from food samples was realized by applying correction factors calculated based on reference standards. NMR spectra were recorded on a Bruker Advance 400 MHz spectrometer, operating at 9.4 Tesla corresponding to the resonance frequency of 400.13 MHz for the 1H nucleus. The NMR spectra was recorded directly on the oil without any sample preparation. The difference between the mean values of the fatty acids content determined by GC-MS and NMR was not more than ± 15% for sunflower oil and lard, and ± 6% for palm oil.

Abstract Nowadays many reports confirmed the effect of different nanoparticles (NPs) on the growth and secondary metabolite production in various microorganisms. Some of them, NPs like Ag, Au and oxides of Al, Ti, Si and Zn have harmful effect on the cells of microorganisms. Iron NPs are expected to be nontoxic, due to using Fe atom in several pathways of cell metabolism and, therefore, low iron toxicity. The use of iron NPs in technologies for remedying polluted environment was caused by their efficiency in reduction reactions, mobility, and high reactivity, due to the high surface area. The present study aims to determine the effect of magnetite (Fe3O4), zero-valent iron Fe(0) NPs, and fluorinated dinitroaniline herbicide trifluralin on growth of mycelial fungi. Fungal strains were isolated from soil long-term polluted with obsolete pesticides, DDT and trifluralin. The inhibition activity of iron NPs and trifluralin was evaluated using express-method. Each fungal strain had an individual reaction to the solutions of iron nanoparticles. At the same time, Fe(0) NPs, as well as magnetite NPs, had a stimulating effect on the formation and maturation of spores of micromycetes. Addition of trifluralin to the culture medium had a growth inhibition effect on micromycetes, but this effect was reduced, when trifluralin was mixed and incubated with iron NPs for 1 hour before.

Abstract Recirculating Aquaculture Systems (RAS) used in aquatic research and production are a viable alternative to traditional open-sea mariculture. The rearing of marine living resources in controlled environments is one of NIMRD’s constant concerns. Golden gray mullet Liza aurata (Risso, 1810) is spread in the Mediterranean, Black and Caspian Seas, as well as along the Atlantic coast, and culture in extensive and semi-intensive enclosures has been practiced worldwide for centuries, especially in the Far East and the Mediterranean, reaching a global production of 134,329 tons in 2010. The species’ potential for aquaculture is enhanced by its eurihalyne and eurithermal adaptability, allowing it to grow in a variety of ecosystems. The biological material used for the experiment was represented by golden gray mullet fingerlings fished using the beach seine from the Black Sea. They were monitored for health state, growth rythm (mean length and weight determinations), behavior under RAS conditions, survival rate and overall adaptability. The growth of juveniles after 90 days was 89.2% for total length and 246% for mean biomass. Concerning overall adaptability, after approximately one month, the golden gray mullet individuals fully adapted to rearing in the RAS tanks and handling during measurements. Moreover, the food administered (Skretting Classic K) was easily accepted, active feeding behavior being observed even in the presence of NIMRD’s staff. The fish’s health state was good, with no mortalities caused by infections or parasites. The survival rate upon completion of the two monitoring months was 76.66% (23 of the 30 individuals included in the experiment). The preliminary results obtained showed a good adaptability and a normal growth rate, which makes Liza aurata a potential candidate for aquaculture targeting the national and regional market.

Abstract Diffuse idiopathic skeletal hyperostosis (DISH) is a systemic non-inflammatory disease of unknown aetiology affecting the axial and appendicular skeleton. The disease is characterised by calcification of soft tissues including tendons, joint capsules, and ligamentous attachments to bone. A retrospective radiographic study was conducted to investigate the presence and distribution of the DISH in dogs. For this goal were revised medical records from the radiology service of Faculty of Veterinary Medicine Bucharest for dogs that had a radiographic report that described the presence of DISH at spine level. The signalments of all dogs were taken from their medical records. From 531 dogs of 19 breeds, 11 dogs (Cross breed = 3; Rottweiler = 3; Boxer = 2; Golden retriever = 2; German shepherd = 1) were diagnosed with DISH, representing 2.07%. Of these, 5 were females and 6 males, aged between 6 and 15 years (an average of 9.81 years). Following the radiographic evaluation, a total of 74 vertebral segments affected by DISH were identified, and the number of vertebral segments affected per dogs varied between 4 and 10. In all cases, the DISH was accompanied by spondylosis deformans. Although the presence of flowing calcification in the ventral aspects of adjacent vertebral bodies is conclusive for classification as DISH, however it is recommended obtaining supplementation data through modern imaging exams on the vertebral structures.

Abstract The paper presents the level of lead in the liver, gizzard, breast muscles and humerus of game birds, shot during the hunting season of 2016 - 2017 in Bulgaria. In quail gizzards (n=10) radiographic examination showed ingested pellets. In turtle doves (n=10), lead levels in the liver had higher values of 2,501 ± 1,404 mg/kg, compared to the maximum levels of <2 mg/kg. The content of lead in the humerus of partridges (n=10) showed a very high concentrations of 54,241 ± 36,731 mg/kg compared to the base level of 10<20 mg/kg. The high levels of lead in the tissues of the game birds, induced by lead shot exposure, are a significant risk to predators and scavengers.

Abstract This study analyzes the results obtained during the agricultural year 2015-2016 on the PHD thesis research field and was carried out on a series of 6 wheat varieties (Triticum aestivum L.), of which 5 Premium wheat varieties and one Class A variety. The purpose of this research is to stimulate the expansion of Premium wheat varieties surfaces in Romania. Due to the superior quality of the grains (protein> 14.5%) their use in bakery, will reduce the use of synthesis enhancers. The location of the experimental field was carried out in Draganesti-Vlasca area, at SCDA Teleorman. The aim was to establish optimal technology to maximize the quantity and quality of the yield. Given the crop rotation after peas, the behavior of the wheat varieties was observed on different nitrogen doses. There were applied 3 fertilization fractions with nitrogen (N1-N3) and 3 treatments with fungicides (V1-V3). Determinations of the main foliar and spike diseases were made. The correlation between fertilizer and fungicide treatments showed the differences between yield potential and disease tolerance of the analyzed varieties.

Given the crop rotation after peas, the behavior of the wheat varieties was observed on different nitrogen doses. There were applied 3 fertilization fractions with nitrogen (N1-N3) and 3 treatments with fungicides (V1-V3). Determinations of the main foliar and spike diseases were made. The correlation between fertilizer and fungicide treatments showed the differences between yield potential and disease tolerance of the analyzed varieties.","PeriodicalId":6413,"journal":{"name":"“Agriculture for Life, Life for Agriculture” Conference Proceedings","volume":"1 1","pages":"45 - 50"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85010088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
