Evaluation microelements and vitamin C content of some spices

In this paper were studied by comparison microelements (Cu, Zn, Ni, Mn, Pb, Co, Cr) and vitamin C content of some commercial spices: ground black pepper (Piper nigrum), sweet paprika, cayenne pepper (Capsicum annuum) and powder cinnamon (Cinnamomum zeylanicum). For this purpose, the mineral elements mentioned were quantified by Atomic Absorption Spectrophotometry (AAS), for their determination was used the atomic absorption spectrophotometer’s contr AA 300, Analytik Jena and the vitamin C content was analyzed by 2,6-diclorindofenol method using as standard ascorbic acid solution, 0.5 mg / ml. This work attempts to contribute to knowledge of the nutritional properties of these plants. These results may be useful for the evaluation of dietary information. Principal component analysis (PCA) was carried out for quantitative mineral concentration and vitamin C content. Among microelements, Cu, Zn and Mn were found in the highest concentration in whole investigated vegetable material

Assessment of greenhouse gas emissions from dairy farming using The Cool Farm Tool

Climate change is one of the greatest challenges mankind has ever faced and could lead to potentially devastating global problems, with a need for urgent mitigation and adaptation. Agriculture, especially livestock farming, is a major driver of climate change through its contribution to the total emissions of greenhouse gases (GHGs). The dairy sector has been identified as an important source of GHG emissions, mainly via carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). In this study, total CO2 equivalent (CO2e) emissions were assessed from a dairy farm (65 dairy cows) located in Romania using the Cool Farm Tool calculator (CFT). We specifically aimed to calculate: (1) the total CO2 equivalent (CO2e) and CO2e per kg FPCM (fat- and protein-corrected milk); (2) methane emissions from enteric fermentation; (3) GHGs resulting from feeding practices; (4) GHGs from manure management; and (5) a simulation of two different scenarios and their impact on GHG emissions. Our results showed annual GHG emissions of 553,170 kg CO2e, almost half of which were released through enteric fermentation. Lactating cows were the major contributor to total GHG emissions, while heifers released the lowest emissions. The two scenarios simulated in this study showed that both the changes made in dairy diet composition and livestock manure management could result in lower GHG emissions. These results confirm the importance and utility of the CFT for the quantification of GHG emissions in dairy farms and its important role as a decision support tool to guide the adoption of good agricultural practices

MARKET ANALYSIS OF FRUIT AND FRUIT CANNEDS

Canned fruit industrywas a period of recession due to funding poor and inadequate management, but shows substantial potential for development, thanks to natural and materials resources that can be recovered efficiently in production/processing and launch policies marketing to promote canned fruits Romanian market and economic space of the European Union.Official data published by Eurostat in February 2015 shows that Romania ranks in the top eight member countries of the European Union, the value of agricultural production. Total production in 2014 was valued at 392.3 billion euros, while our country has produced worth 15.4 billion euros.This paper addresses theoretical and comparative market developments canned fruits, relevant data of economic efficiency of production and marketing strategy role in this branch of commercial activity. It is also highlighted developments and prospect market canned fruits in Romania

Technical - economic evaluations experimental casuistry studied at core walnut oil

In this paper was performed study regarding guide technical and economic evaluations for core walnut oil obtained by extraction with petroleum ether, in a industrial unit considering 240 working days/year. The economic efficiency relies on analytic and synthetic indicators that give a general view about the production process. These indicators are used in order to calculate the profit of the factory enterprise. Monitoring of plant resources are essential for the development of modern agricultural production. Biodiversity of plant resources in agriculture is a biological basis for assurance the quality of world food products, for creating new cultivars, through conventional crossing process or application of biotechnology. The values obtained were as follows: total costs (736215 Euros/year), total revenues (817800 Euros/year), profit (81585 Euros/year), profit rate (11.08%), product cost (73400.63 Euros) and production costs (1301 Euros/kg). The results of technical-economic calculations estimated have positive values, suggesting that processing technology is profitable, the costs being lower than revenues, and therefore can be recommended as a potential technology solution for recovery of core walnut

Comparative analysis of chlorophyll and carotenoid pigments content of arugula (Eruca sativa) and lettuce (Lactuca sativa) leaves

The aim of this study was to analyze the chlorophyll and carotenoids content of fresh arugula (Eruca sativa, Ruca variety) and lettuce (Lactuca sativa, Marilena variety) leaves from the Romanian market. The pigments concentration in the analyzed samples was determined by a spectrophotometric method. In both analyzed samples, chlorophyll "a" predominates to chlorophyll "b". The highest content of chlorophyll pigments was found in leaves of arugula: 31.47 mg/g, while in the lettuce leaves was found a concentration of 27.14.Arugulaleavesare alsothe richestincarotenoids (245.50 µg/g)

The Response of Two Chokeberry Cultivars to the Influence of Climatic Factors in Bistrita Area, Romania

Black chokeberry (Aronia melanocarpa Michx.) is one of the most cultivated species in recent years, gaining consumer appreciation due to its fruit’s bioactive compounds. This aim of this paper was to study the behavior of two chokeberry cultivars ‘Viking’ and ‘Galicjanka’ under climatic factors in Bistrita area, within an experimental plot established at Fruit Research and Development Station Bistrita. Resistant to low temperatures but sensitive to drought, the two chokeberry cultivars ‘Viking’ and ‘Galicjanka’, have recorded a positive development evolution in pedoclimatic conditions in Bistrita area. For the success of this crop, it is necessary to ensure all the parameters to obtain a high-quality production, so that the deficiencies caused by insufficient water supply can be prevented by implementing technological measures that reduce the negative impact of the ever- changing environment

New Biomarkers in Screening Anthracycline-Induced Cardiotoxicity Only with Peripheral Blood Sampling

Because oxidative stress after administration of doxorubicin was identified as playing a central role in cardiac dysfunction, we hypothesized that the expression (or overexpression) of TLR2 and TLR4 contributes to the pathogenesis of doxorubicin-induced cardiac dysfunction. Toll-like receptors (TLRs) are members of the interleukin-1 receptor family (IL1) and are involved in the ability to react to the molecular trigger associated with pathogenic microorganisms. Recent studies have shown that TLR receptors are activated by endogenous signals, such as heat shock proteins and oxidative stress, which can contribute to congestive heart failure. Until recently, the best detection method for cardiotoxicity induced by anthracyclines was myocardial biopsy. Other early screening and early diagnosis methods (biomarkers—cardiac troponins and natriuretic peptide) have not yet proven their efficacy. Our proposed method is a new, revolutionary one that does not imply any kind of physical (and psychic) aggression on the patient: the targeted genetic (TLR2/TLR4) analysis of the human peripheral blood (which is a minimally invasive procedure)
