    The urolithiasis in cats represent 15% of the total cases with UTD (Urinary Tract Disease) to this species. Out of these, 50% are proving to be composed of phosphate ions, ammonium and magnesium. To date, a multitude of factors that could be leading to the development of this stones are known. However, their treatment and control still representes a medical challenge. The study has been done on a number of 8 cats, 4 castrated males, 2 intact males and 2 sterilised female. The impact of the food that had been fed to the subjects had upon the development of the phosphate-ammonium- magnesium uroliths, as well as the impact of the post-diagnose diet, had been carefully analysed. As a result, the excess of 5 risk factors in the struvite lithogenesis from their daily diet before the diagnosis. Their values had been compared with those found in the speciality literature for the same risk threshold. From the perspective of this pathology's development, the results have revealed in all eight cases an excess of calculogenic factors in their pre-diagnose diet. However, it did not reveal an influence over the struvite disolution. The next step was to study the treatment's evolution from using two commercialy available products, fomulated for the treatment and prevention of the studied urolithiasis. The results have concluded the efficacy in the complete dissolution of the struvite of just one of them

    This study aims to analyze the evolution of winter wheat production, between 1996 and 2018, under the influence of 25 fertilization combinations with nitrogen and phosphorus. Nitrogen fertilizers applied have graduations of 0,30,60,90 and 120 kg active substance/ha, and of phosphorus 0, 40,80,120 and 160 kg of active substance/ha. The research carried out on a typical chernozem in the West of Romania showed that the fertilizers are well used by the winter wheat crop. During the 1996-2018 period, the influence of chemical fertilizers with nitrogen and phosphorus has been studied in a 3 years rotation (soya bean- wheatmaize). Unilateral application of nitrogen and phosphorus bring production increases within the range 573 kg grains/ha - 1016 kg/ha, nitrogen and 282 kg grains/ha - 998 kg/ha, phosphorus. The obtained results highlight the fundamental role of the combined application of the two types of fertilizers. The optimal dose of fertilizer, from an economic point of view is N88P122, with a production of 6866 kg wheat/ha

    Pleurotus eryngii mushrooms are widely produced for their excellent nutritional and medicinal qualities. This experiment was conducted to investigate the yielding capacity of three P.eryngii strains (Pery-G, Pery-K and Pery-26) cultivated on three variants of lignocellulosic substrate, four replicates/variant. The trail was performed in the mushroom house and the spawned bags (2 kg substrate) were randomized on racks with two levels. Pery-G strain showed the biggest production in the V2variant (75% straws + 20%sawdust + 5% wheat bran and corn flour 1/1) with 544 g/bag (27.20%) and in the V1(95% straws + 5% wheat bran and corn flour), with 534 g/bag (26.70%). Pery-26 strain yielded the best result of the experiment in the V2 with 548 g/bag (27.40%). All three experimental strains yielded the smallest harvests in the V3 variant (50% straws + 30% sawdust + 15% corn cobs + 5% wheat bran and corn flour 1/1)

    Étant donné que la taille de la vigne produit chaque année une grande quantité de déchets inutilisables, le but de cette étude était d'évaluer le potentiel des baguettes de vigne à être utilisées comme source naturelle de composés bioactifs pour les industries alimentaire, pharmaceutique et cosmétique. Afin d'optimiser les procédures d'extraction phénoliques, les baguettes de vigne de raisin de Cabernet Sauvignon ont été extraites avec diverses concentrations d'éthanol (0, 50, 70, 90 et 96%) et d'hydroxyde de sodium 1N, dans un rapport matière végétale/solvant de 1:10. Pour purification ultérieure sur des cartouches C18SPE préconditionnées, les surnageants ont été concentrés à sec dans un évaporateur rotatif sous vide. Après avoir déterminé la concentration optimale en solvant, le temps (<300 min) et la température (20, 40, 60 °C) nécessaires pour maximiser l'extraction des composés phénoliques ont été testés. La concentration la plus élevée en polyphénols a été obtenue lorsque l'extraction a été réalisée sur des baguettes de vigne broyées (particules <0,5 mm), avec une solution d'éthanol 70%, 4 heures à 60 °C. Après application de températures élevées, l'activité antioxydante et le pouvoir réducteur ferrique des extraits sont restés élevés(94,01% de DPPH nettoyé). Les résultats de la recherche indiquent que les baguettes de vigne sont sources durables de composés polyphénoliques avec fonction sanogène, actuellement inexploitées au potentiel technologique et économique réel

    The present research was conducted under laboratory conditions. The purpose of research was to investigate the potential of priming with press mud, peat moss, sand, gunny bags, compost, farm yard manure and moringa leaf extract (MLE) on seedling growth and germination capacity of maize seed. Untreated or non-primed seeds were used as a control treatment. Priming treatments improved germination capacity, stand establishment and seedling vigor, compared with control. Priming with moringa leaf extract enhance germination and seedling vigor of maize seed, compared with the control and other seed primed treatments. In moringa leaf extract primed seeds, root and shoot growth was improved. Overall, moringa leaf extract primed maize seeds performed better than all other treatments and it could be related by seedling vigor enhancement and lowering the mean germination time, due to imbibition of higher quantity of water and earlier enzymatic activity. The results propose that moringa leaf extract priming treatment had the potential to enhance germination, stand establishment and early growth of maize seeds

    No full text
    Monitoring the behavior in service stage of civil engineering structures is absolutely necessary for ensuring stability and safety through their exploitation. Achievement of an efficient monitoring process of structures is done by using modern topo-geodetic methods and techniques which guarantees the correctness of the data with the highest accuracy of the obtained results. The progress of the equipment area for determining geometric elements, means of calculation and reporting data influences the upgrade of methods and procedures in topographic measurements. The purpose of this paper is to implement the theory of decision using qualitative and quantitative criteria in a cycle of observations in monitoring the behavior in time of a viaduct engineering structure using three different topographical devices. We proposed a comparative analysis using three topo-geodetic technologies for monitoring vertical spatial displacements. The accuracy with which the monitoring marks are determined on the viaduct is extremely important for obtaining an optimal monitoring system over time. The objective described in this paper is in the North- West part of Galati city, which is a structure over 50 years old with a length of 1.3 kilometers. The viaduct is an important access road DJ 252 (Galaţi-Matca-Tecuci) that links the city of Galati to the platform of Arcelor Mittal steel plant, requiring permanent monitoring due to the age and the continuous dynamic actions it was subjected to during the exploitation and which can transmit to the foundation ground important settlings that cause irrecoverable structural degradation

    The influence of treatments with different phytosanitary products (fungicides) on the attack of some phytopathogenic fungi and on wheat harvest – andino variety - in 2017 pedoclimatic conditions of the Eastern Bărăgan

    This study aims at monitoring the dynamics of the occurrence and evolution of the attack of some pathogenic agents to wheat – Andino French variety. Among these, we mention: Puccinia recondita f. sp. tritici (sin. Puccinia triticina) which produces wheat’s brown rust and Septoria sp which produces wheat’s brown leaf spotting (septoriosis). Also, the influence of applying these fungicides on the harvest was monitored, as compared to the untreated control variant. 2 experiments with 4 variants (3 variants with phytosanitary treatment, plus a control variant not treated) were taken into consideration for this study, for which 3 phytosanitary products were used, as follows: FALCON 460 EC (proquinazid + tebuconazole+ prochoraz); MYSTIC 250 EC (tebuconazole); TOPSIN 500 SC (thiophanate-methyl); BUMPER 250 CE (propiconazole). The treatment variants were the following at the first experiment: V1 – FALCON 460 EC – 0.6 L/HA 1 treatment applied at straw’s extension + 1 treatment applied at berries’ filling; V2 – MYSTIC 250 EC 0.5 L/HA -1 treatment applied at straw’s extension (0.6 l/ha) + 1 treatment applied at berries’ filling (0.7 l/ha); V3 – TOPSIN 500 SC 1 L/HA + BUMPER 250 CE 0.25 L/HA - 1 treatment applied at straw’s extension + 1 treatment applied at berries’ filling; V4 – Control variant not treated. The experiment was placed in Latin square, the 4 variants being placed in 4 repetitions. Among the pathogenic agents under monitoring, Puccinia recondita f.sp. tritici fungus, producing the brown rust and fungi from Septoria sp. species, producing the brown leaf spotting (septoriosis), had produced the greatest attacks. The first two leaves placed under the wheat ear had been analyzed for the above. These observations had led to the conclusion that for all 3 treatment variants, the degree of attack (D.A. %) of the two diseases was more reduced than at the untreated control variant. The harvests of the treated variants (V1 – 9.14 t/ha, V2 – 9.32 t/ha, V3 – 8.55 t/ha) were higher than the harvest of the untreated control variant V4, being of 8.69 t/ha. The treatment variants at the second experiment were identical with the ones from the first experiment in what concerns the products used. The difference consisted in the fact that one single treatment was executed at wheat plants’ blooming at the second experiment. For this experiment, the harvests were: 8.497 t/ha at the untreated control variant (V4), while at the other 3 variants were: V1 – 9.625 t/ha, V2 – 9.570 t/ha and V3 – 8.442 t/ha
