The Effect of Dehulling Lupine Seeds (Lupinus albus L.) from Low-Alkaloid Varieties on the Chemical Composition and Fatty Acids Content
No full textThe aim of this study was to analyze the effect of dehulling white lupine seeds (Lupinus albus, cultivar Amiga) on the raw chemical composition and nutritional profile of lipids. There was no significant differences (p ˃ 0.05) between whole and dehulled lupine seeds in respect of their content in dry matter, ether extract, crude ash and nitrogen-free extract. However, the dehulled lupine seeds had a higher (p ˂ 0.05) crude protein level (51.69% of DM) than whole seeds (43.16% of DM), and a lower (p ˂ 0.05) crude fiber content (4.35% of DM) compared to that of whole seeds (14.15% of DM). The fatty acids profile is not affected (p ˃ 0.05) by the dehulling process. Oleic acid (C18:1 cis-9) is the main fatty acid in lupine seeds, and the level of monounsaturated fatty acids (MUFA) is slightly higher in whole seeds. The n-3 / n-6 report is adequate in both whole (0.88) and dehulled (0.94) seeds, and the favorable polyunsaturated index (PI) indicates the high content of polyunsaturated fatty acids (PUFA), which indicates that lupine seeds are a valuable source of essential fatty acids. Also, lupine seeds are characterized by favorable values of the thrombogenic (0.18) and atherogenic (0.14) indexes, and an appropriate hypocholesterolemic/hypercholesterolemic index value, features considered important for human health and animal nutrition
Researches on leadership abilities projection
No full textWithout any doubt, through their behaviour, leaders have a major impact on people, culture, society, but not least on the performance of an organization. All programes that require organizational changes start from the premises of first understanding the fact that the influence of people that hold the authority is vital for the company᾽s succes. At the level of an organization, leadership development starts by first making an evaluation plan on all its levels. It is of extreme importance starting with a research-action approach, so as to be able to project leadership skills and ways they can be improved. Research – based actions use the gathered data to involve every person in the organization and understand its role (testing phase) and then project practical actions throughout awareness, acceptance and actios, and finally changes, that are recommended to the superior managemen t (the action phase). The present analysis aims to highlight the importance of projections that are made on a research basis and conduct to efficiency and productivity in a proactively way. Projecting leadership abilities in a company influences the entire organization, from an individual person to a group and finally to the entire organization. The paper also focuses on showing how internal personal changes can influence the whole sistem, make it sensitive to external changes and able to quickly adapt
Bioethanol Production from Vineyard Waste by Autohydrolysis Pretreatment and Chlorite Delignification via Simultaneous Saccharification and Fermentation
No full textIn this paper, the production of a second-generation bioethanol from lignocellulosic vineyard cutting wastes was investigated in order to define the optimal operating conditions of the autohydrolysis pretreatment, chlorite delignification and simultaneous saccharification and fermentation (SSF). The autohydrolysis of vine-shoot wastes resulted in liquors containing mainly a mixture of monosaccharides, degradation products and spent solids (rich in cellulose and lignin), with potential utility in obtaining valuable chemicals and bioethanol. The autohydrolysis of the vine-shoot wastes was carried out at 165 and 180 °C for 10 min residence time, and the resulted solid and liquid phases composition were analysed. The resulted liquid fraction contained hemicellulosic sugars as a mixture of alpha (α) and beta (β) sugar anomers, and secondary by-products. The solid fraction was delignified using the sodium chlorite method for the separation of lignin and easier access of enzymes to the cellulosic sugars, and then, converted to ethanol by the SSF process. The maximum bioethanol production (6%) was obtained by autohydrolysis (165 °C), chlorite delignification and SSF process at 37 °C, 10% solid loading, 72 h. The principal component analysis was used to identify the main parameters that influence the chemical compositions of vine-shoot waste for different varieties

No full textTaking into account the fact that at present the population is in a continuous fight against the food additives, part of the dairy products has started to be indispensable. The quality of the cheeses is mainly outlined by defining the sensory and physical-chemical characteristics, these being the defining ones in the consumers' decision. To obtain superior dairy products we need a very good quality raw milk. Therefore, through this paper we set out to analyze the stages of the technological flow of obtaining salty cheese as well as of the sensory and physico-chemical analyzes on the finished product but also on the raw material. Regarding the quality of the analyzed milk, the average values calculated were 4.01 ± 0.03% for the fat content, and 1.030 ± 0.001g / cm3 for the density. For the final product, salty cheese, sensory analyzes and physico-chemical determination were performed in order to establish the qualitative parameters. Also analyzed were the stages of the technological flow by monitoring the parameters, all of which lead to obtaining a product that can be marketed within USAMV-Iasi

Metale grele: o sursă de contaminare pentru plantele medicinale şi posibile implicaţii asupra sănătăţii umane
No full textDue to the antioxidant properties of medicinal plants and their beneficial effects on human health, theyare used and consumed as natural medical sources. Despite this, due to the current pollution of environmental compartments (soil, water, air), they can be contaminated with various pollutants. Heavy metals are a category of toxic compounds of great interest, due to the negative action on the environment and human health. Although some heavy metals are important in maintaining the proper functioning of plants, in high concentrations, they can become toxic. In the context of heavy metal pollution of the environment and possible contamination of medicinal plants with these pollutants, the need for chemical analysis of toxic plant compounds is necessary. This paper approaches results from literature which show that medicinal plants can be subjected to contamination with heavy metals, and this has the consequence of altering the normal functions of medicinal plants. Moreover, following consumption through the food chain (soil -plant -human or soil -plant -animal -human), human health may be endangered. This paper also investigates the toxic action of heavy metals in plants, represented, in principle, by the production of reactive oxygen species (ROS), enzyme inhibition and damage to antioxidants
Pelophylax ridibundus (Amphibia: ranidae) as paratenic host of Spirocerca lupi species (Secernentea: spirocercidae) in the Republic of Moldova
No full textThe paper presents data on the identification of the helminth fauna structure of Pelophylax ridibundus species and the determination of its role as intermediate and paratenic host for various groups of vertebrate helminths. 84 specimens of Pelophylax ridibundus (26 - males, 31 - females, 27 - juveniles) from the Dniester River, border area of Talmaza village, Ștefan Vodă district, were helminthologically investigated. As result of helminthological investigations, it was
established that the structure of the helminth fauna of Pelophylax ridibundus species is characterized by 13 species of helminths (Haematoloechus variegatus Rudolphi, 1819; Codonocephalus urniger Rudolphi, 1819; Opisthioglyphe ranae Froelich, 1791; Paralepoderma brumpti Buttner, 1951; Prosotocus confusus Looss, 1894; Tylodelphys excavata Rudolphi, 1803; Diplodiscus subclavatus Pallas, 1760; Parastrigea robusta Szidat, 1928, Strigea falconis Szidat, 1928; Cosmocerca ornata Dujardin, 1845; Oswaldocruzia filiformis Goeze, 1782; Icosiella neglecta Diesing, 1851; Spirocerca lupi Rudolphi, 1809), from 13 genera, 11 families (Omphalometridae, Haematoloechidae, Plagiorchiidae, Lecithodendriidae, Diplodiscidae, Diplostomatidae, Strigeidae, Cosmocercidae, Molineidae, Onchocercidae, Spirocercidae), 6 orders (Plagiorchiida, Echinostomida, Diplostomida, Ascaridida, Strongylida, Spirurida), 2 classes
(Trematoda, Secernentea) and 2 phylums (Plathelminthes, Nematoda). Of the 13 helminth species detected, a special importance is attributed to the nematode Spirocerca lupi Rudolphi, 1809, for which the taxonomic classification, synonims, hosts, organic specificity and biological cycle are described, for which the Pelophylax ridibundus species is
as paratenic host. The diversity and intensity of helminth infestation of Pelophylax ridibundus has been established
