Studies Regarding Tailings Pond Seepage Water from Mining Activities over Avena sativa L. Germination Influence

Cultivation of oat in the limiting areas of tailings pond might be regarded as one of the possibilities that could lead to the general amelioration of these places. In order to characterize the waste products, to determine and evaluate the components that may be leached from waste products and that can affect the limiting areas of tailings pond, leaching tests were performed. In this paper, we have observed the influence of eluate, obtained from leaching tests, on seed germination, radicle and coleoptyle development as well as on the amount of accumulated dry matter for Avena sativa L., genotypes. According to our researches, we may conclude that the studied genotypes of Avena sativa L. showed tolerance to eluate while values registered for seed germination, radicle and coleoptyle development as well as dry matter content were comparatively higher than those registered for the control variant

Research regarding the main production and quality indices of some corn hybrids cultivated in the Banat area

In this paper we have studied the main indices of quality and production of 20 maize hybrids cultivated in climatic conditions specific to the Banat area. For this purpose we have grown in terms of conventional technology the 20 hybrids in comparative production plots of 0.5 ha / hybrid, the experimental field being located in Becicherecul Mic. Through this experiment we determined the following parameters: leaf area, productivity and the amount of starch and protein in beans. Experiments have shown that there are significant genetic differences among the 20 hybrids studied both in terms of quality and productivity. The leaf area was determined using a portable AM-300 scanner, recorded values being between these limits 2680 cm2 /pl and 5877 cm2 /pl, the experience media determined was 3767 cm2 /pl. The determinations were made when the plants were in stage 7.9 according to BBCH decimal unit code. Increased average leaf area / plant is directly influenced by the early stage of studied hybrids, the best results occurring in early hybrids. Regarding production qualities the results pointed out that productivity limits ranged between 10.25 t / ha in early hybrids and 14.87 t / ha for full mid season maturity hybrids. Grain quality was determined using a grain analyzer after NIR method. The main quality attributes tracked were: grain content in starch and protein substances. Thus in terms of starch content best results were obtained in full mid season maturity hybrids (79.47 %) while higher protein content was recorded in short mid season maturity hybrids (10.27 %)

Cytokines’ Involvement in Periodontal Changes

The bacterial challenge on the periodontal tissues triggers an inflammatory reaction, driven by pro-inflammatory cytokines, that eventually leads to the periodontal structures’ damage. The pathogenic mechanisms of this inflammatory reaction are complex and are influenced by the type of host-immune response and certain local and systemic factors. These factors can influence periodontal inflammation, through the action of the various pro-inflammatory cytokines. Periodontal disease and certain systemic conditions can have a mutual association, as the pathogenic mechanisms of these diseases can involve similar molecular and cellular elements. The concept of ‘periodontal medicine’ comprises these pathogenic connections, focusing on the key role that periodontal health has on the general homeostasis and well-being

Effect of Fertilising Fodder Chicory on Fodder Quality

The nutritive value of fodder chicory is close to the quality of fodder alfalfa, i.e. under certain technological conditions, fodder chicory has a higher nutritive value and more raw protein. Studies show that over three experimental years, the content of raw protein reached values ranging between 23.69 and 25.26% with mineral fertilisation and between 21.88 and 22.81% with organic fertilisation, compared to only 21.06% in the control variant. Depending on the content of raw protein, the amount of raw protein increased with 40.7% with mineral fertilisation and with 22.4% with organic fertilisation, compared to the control variant

Effect of Bacterial Inoculation and of Nitrogen Fertilisation on Fodder Quality in Some Grass and Fodder Legume Species

Increasing the biological nitrogen fixing capacity through inoculation with improved stems of nitrogen fixing bacteria is an important measure of increasing total nitrogen content in legumes due to the supply of fixed nitrogen. Research on perennial legume species sowed in pure culture or in mixture with perennial grass species showed that in the variants inoculated the content of total nitrogen was close to the content of total nitrogen in the variants fertilised with N100. Mean data for the three vegetation years show that bacterial inoculation of the legumes contributes with 11.5% to the increase of the content of total nitrogen in the plants, while fertilisation with N100 has an almost similar contribution (11.0%)

Assessment of some morphological and physiological parameters in lettuce (Lactuca sativa l.) cultivated in hydroponic system

Lettuce is a valuable leaf vegetable for a well-balanced diet, since it is rich in nutrient elements, has low calories and provides dietary antioxidants. Compared to soil-based cultivation, the hydroponic system is an alternative associated with a shortening of growing cycles and a reduction of wasted water amount. The aim of this study was to analyze the growth of lettuce plants under hydroponic and soil cultivation systems, during three phenological growth stages (45; 47 and 49) according to BBCH scale. During the study different morphological and physiological parameters were evaluated: Plant height (PH); Stem diameter (SD); Fresh mass (FM); Dry mass (DM); Leaf area (LA); Chlorophyll content (CC); Transpiration rate (TR). The research was carried out using a complete randomized design with a 2 × 3 factorial arrangement of cultivation system and growth stages. Plants grown in hydroponic system presented higher values of most parameters, except for DM and TR. The cultivation system had the highest effect on PH, SD and LA. The highest variation between growth stages were observed for PH, LA and CC. Finally, we can conclude that lettuce plants cultivated under hydroponic system, presented better growth parameters associated with higher head weight and yield

Influence of seed size and weight used in sowing on common bird’s-foot-trefoil (Lotus corniculatus L.) Plant vigour

Growth and development of common bird’s-foot-trefoil (Lotus corniculatus L.) plants are influenced by seed size and weight upon sowing. Studies show that the five seed size groups influence plant vigour, i.e. a 2-4 times increase of morphological organs (roots, seedlings, leaves) in larger and heavier seed group than in smaller and lighter seed group. This increase was also pointed out by the strong correlations between seed size and plant vigour

Daily Share of Green Matter in Pure or Associated Fodder Chicory

Chicory (Cichorium intybus L.), used as fodder, has some favourable features: high longevity, resistance to drought and to soil conditions (acidity, alkalinity), cultivable pure or associated with different grassland species, quick recovery after mowing or grazing, high degree of consumability, high nutritive value. Research shows that chicory, sowed pure or in association with legume species or with grassland grasses, produces daily, depending on vegetation duration, important amounts of green matter, i.e. between 120 and 280 kg/day/ha without or with nitrogen fertilisation (N150)

Oral and Periodontal Implications of Hepatitis Type B and D. Current State of Knowledge and Future Perspectives

Periodontitis is characterized by low-grade inflammation of the periodontal tissues, the structures that support and connect the teeth to the maxilla and mandible. This inflammation is caused by the accumulation of subgingival bacterial biofilm and gradually leads to the extensive damage of these tissues and the consequent loss of teeth. Hepatitis B is a major global health concern; infection with the hepatitis B virus causes significant inflammation of the liver and the possibility of its gradual evolution to cirrhosis. Hepatitis D, caused by infection with the delta hepatitis virus, is manifest only in patients already infected with the type B virus in a simultaneous (co-infected) or superimposed (superinfected) manner. The dental and periodontal status of patients with hepatitis B/D could exhibit significant changes, increasing the risk of periodontitis onset. Moreover, the progression of liver changes in these patients could be linked to periodontitis; therefore, motivating good oral and periodontal health could result in the prevention and limitation of pathological effects. Given that both types of diseases have a significant inflammatory component, common pro-inflammatory mediators could drive and augment the local inflammation at both a periodontal and hepatic level. This suggests that integrated management of these patients should be proposed, as therapeutical means could deliver an improvement to both periodontal and hepatic statuses. The aim of this review is to gather existing information on the proposed subject and to organize significant data in order to improve scientific accuracy and comprehension on this topic while generating future perspectives for research
