Mineral Profile of Some Dried Fruits

The aim of this work was to determine the content of 16 elements in the seven samples of dried fruits: plums (Prunus domestica), figs (Ficus carica), apricots (Prunus armeniaca), white and black raisins (Vitis vinifera), dates (Phoenix dactylifera) and cranberries (Vaccinium oxycoccus), which are available in local markets. Inductively coupled plasma optical emission spectrometry (ICP-OES) was used after wet digestion method. Potassium is the most common macroelement while boron and zinc are the most common microelements. As, Cd and Hg were not detected while the content of Pb is below the MAC. The obtained results were statistically analyzed and compared with the literature values

Automated Fingerprint Identification System: with and without the Possibility of Correction of a Digitalised Image

According to the fact that systems for automatic processing of biometric data are constantly advancing in terms of speed and reliability, as well as in terms of adding new processing capabilities, the question of choosing the appropriate system becomes more important. In this paper the idea is to present the technical and technological solutions of the Automated Fingerprint Identification System with different operating principles, with and without the possibility of correction or coding of a digitized image. Comparisons of different systems were performed in test and production environments. The test database with 10 000 records and about half a million records of dactyloscoped persons in the production of database for testing the performance of search was used. The results have shown that there exists a statistically significant difference (p < 0.001) between examined systems in face fingerprint search according to latent fingerprint databases (which means indirect verification). In the production environment, it was found that there exists statistically significant difference (p < 0.001) in the direct and indirect verification showing advantages and disadvantages of the compared systems

Hepatitis C: Host and Viral Factors Associated with Response to Therapy and Progression of Liver Fibrosis

The goal of this study was to identify the baseline host and viral factors of response to antiviral therapy in patients with chronic hepatitis C. Compared with interferon/ribavirin therapy, new current direct-acting antiviral (DAA) combination regimens significantly increased rate of sustained virologic response (SVR) and shorter treatment durations, but is still limited by viral resistance, adverse effects, and high cost especially in developing countries. Human genetic factors and heterogeneity within the HCV genome may be associated with virologic treatment failure before and after antiviral therapy. Further, HCV infection may contribute to the development of HCV-related liver disease and hepatocarcinogenesis, through modulating genetic and epigenetic state of certain genes implicated in control of critical cellular pathways. Previous results confirm the importance of host and viral factors and virus-induced genetic and epigenetic changes in predicting outcome and treatment response

Correlation analysis of milk production traits across three generations of Simmental cows

The relationship between milk production traits over whole lactations was evaluated across three generations of Simmental cows (between daughters, dams and granddams) by a corelation analysis with whole lactation traits in the daughter generation being used as the dependent variables (x&lt;sub&gt;1&lt;/sub&gt;), and those in the dam and granddam generations being used as the independent variables (x&lt;sub&gt;2&lt;/sub&gt; and  x&lt;sub&gt;3&lt;/sub&gt;). The results were obtained from a sample of 1170 daughters and as many dams and  granddams. The correlation of whole lactation milk production traits between daughters, dams and  granddams, as calculated by simple, partial and multiple correlation coefficients was very weak or  non-existent. All of the calculated simple and partial correlation coefficients were positive and mostly  statistically very significant (P&lt;0.01). The calculated coefficients of multiple correlation (R1.23) between  lactation length, milk fat content, milk yield, milk fat yield and 4% FCM yield with the expression of the traits in the daughters being used as the dependent variable and that in the dams and granddams as the independent variable were statistically very significant (P&lt;0.01), amounting to 0.091, 0.251, 0.180, 0.133 and 0.153, respectively.Key words: Simmental breed, production traits, generation, coefficient of partial correlation, coefficient of multiple correlation

Prinos suve mase lucerke u zavisnosti od sorte, faze razvića i otkosa

The main objective of this study was to assess dry matter productivity of different alfalfa cultivars depending on stage of maturity and cut, as well as the optimal time of harvest to achieve the maximum yield. Dry matter yield of alfalfa and red clover depended on all three factors and their interactions. The local variety of alfalfa, K 28, was more productive (from 6,8 to 2,3 t ha-1 from first to fourth cut, and from 3,4 to 5,5 t ha-1 from first to third stage of development) compared to US variety, G+13R+CZ (from 5,9 to 2,2 t ha-1 from first to fourth cut, and from 2,7 to 5,2 t ha-1 from first to third stage of development). The maximum yield of K 28 variety could be achieved by cutting alfalfa five times a year.Cilj ovih istraživanja je bio da se utvrdi produktivnost različitih sorti lucerke u zavisnosti od faze razvića i otkosa, kao i optimalno vreme košenja radi postizanja maksimalnog prinosa. Prinos suve materije lucerke zavisio je od sva tri ispitivana faktora i njihovih interakcija. Domaća sorta lucerke je produktivnija (6,8 do 2,3 t ha-1 od prvog do četvrtog otkosa, odnosno od 3,4 do 5,5 t ha-1 od prve do treće faze razvića) u odnosu na američku (5,9 do 2,2 t ha-1 od prvog do četvrtog otkosa, odnosno od 2,7 do 5,2 t ha-1 od prve do treće faze razvića). Maksimalan prinos sorte K-28 mogao bi se postići kosidbom pet puta godišnje

The influence of polymer addition on flexural strength, fracture mode and porosity of traditional ceramics

The usage of air-swept milling of raw materials is the most efficient method for preventing the negative lime-blowing process of ceramic roofing tiles. How-ever, after air-swept milling the clay minerals lose water which has to be re-turned back before the shaping procedure. Addition of surface active materials could increase hydrophilicity of the raw material and reduce needed time for re-wetting trough the control of meso-, micro- and nanoporosity of the clay ma¬terial. In view of that, the object of this research was to study the influence of polyethylene glycol (PEG600) on porosity, mechanical properties and fracture surface characteristics of traditional ceramic materials. It was founded that with the addition of polyethylene glycol (PEG600) to traditional clay materials it is possible to achieve desired porosity, from meso, through micro and up to na¬no, without degrading the mechanical properties of the final products

Effect of Nitrogen Fertiliser and Lime on the Floristic Composition, Soil Microbes and Dry Matter Yield of Danthonietum calycinae Grassland

Natural grasslands are significant resources for forage production, which is not exploited enough, mostly because of low production, as a result of bad grasslands management. The research has been carried out on the association Danthonietum calycinae to evaluate the effects of different nitrogen application rates (N20, N80 and N140) and lime (1 tha-1) on the floristic composition, soil microbes and dry matter yield. Botanic composition was strongly influenced by the treatments, especially by N applications. Nitrogen fertilisation led to significant increase of grass species in the association (from 57% to 82%), while higher rate of nitrogen caused a significant decrease of plants from other families (especially legumes). Application of low and medium rate of nitrogen positively effect on microbial abundant in soil, but the highest dose (140 kg N) reduced all microbial count, except fungi. Mineral nitrogen fertilisation had a favourable effect on dry matter yield in all treatments. The highest increase in dry matter yield relative to the control was in N140 treatments (6.66 t ha-1). Results indicated that optimal applications of nutrients for this association is application of PK and lime and 80 kg of nitrogen which enable high yield (6.38 t ha-1) in comparison with control (3.16 t ha-1) and preserving soil fertility and the environment at the same time

Uticaj fiksnih i kontinuelnih ambijentalnih faktora na proizvodnju 4% mast-korigovanog mleka u prve tri laktacije kod krava simentalske rase

The effect of paragenetic factors on 4% FCM yield in complete and standard lactations was studied in 241 Simmental cows. Farm, lactation number, birth season, calving season, their interactions and age at first conception were evaluated for their effect on the trait. The mathematical and statistical analysis of the data obtained, i.e. least square means, standard error, analysis of variance and coefficient determination, were calculated using the General Linear Model procedure. The effects of farm, lactation group and year of birth on the trait were very highly significant (P 0.05) on the production of 4% FCM, either in whole or in standard lactations. The interaction between birth season, calving season and year of birth was variable and ranged from insignificant to very significant. Age at first conception produced a significant (P0.05) effect on 4% FCM yield in complete and standard (bxy=0.693ns) lactations, respectively.Uticaj paragenetskih faktora na proizvodnju 4%MKM u celim i standardnim laktacijama ispitivan je na uzorku od 241 krave simentalske rase.
