The aims of this study is to identify the most appropriate depths for getting water in the Lake of Radoniqi, Kosovo. We have analyzed physical and chemical indicators such as iron (Fe), aluminium (Al), manganese (Mg), ammonia, nitrites, nitrates etc. Also we have measured phosphorus ions at five levels of Radoniqi Lake. We have measured permaganat of potassium consumption, dissolved oxygen, turbidity and the bed smell aroma. Samples of water were analyzed in the physico-chemical laboratory of Filtration and Treatment Station for drinking water of Radoniqi, in Gjakova. Methods are using such as pH meters, conductivity turbidometrija, atomic absorption, classical spektrofotometrik methods, chemical analysis etc. The results obtained show that the water of the lake "Radoniqi" have a good quality in the level four and five. The removal of water bed aroma is accomplished through treatment with activated carbon in Gjakova Water Treatment and Filtration Station.Keywords: lake, water, parameters, methods, results, filter station

Judicial Control over Public Administration

Abstract Judicial control of administration and installation of courts as specialized institutions for resolving administrative disputes (conflicts) strengthened legitimacy, efficiency and accountability of the administrative bodies and this contributed to strengthening the protection of human rights against administrative bodies. The paper attempts to address the administrative disputes (conflict) in general hence giving specific data for some European countries and USA. Access to thesis topic is analytical and contributes to the recognition of administrative disputes as legal and functional mechanism in building the rule of law. The paper will result with appropriate conclusions that reflect the work of institutions and administrative disputes (conflict) itself as a legal instrument and will help the concerned parties, officials, judges, researchers for theoretical and practical importance of administrative disputes (conflict)

Phosphorylation of more than one site is required for tight interaction of human tau protein with 14-3-3ζ

AbstractSerine residues phosphorylated by protein kinase A (PKA) in the shortest isoform of human tau protein (τ3) were sequentially replaced by alanine and interaction of phosphorylated τ3 and its mutants with 14-3-3 was investigated. Mutation S156A slightly decreased interaction of phosphorylated τ3 with 14-3-3. Double mutations S156A/S267A and especially S156A/S235A, strongly inhibited interaction of phosphorylated τ3 with 14-3-3. Thus, two sites located in the Pro-rich region and in the pseudo repeats of τ3 are involved in phosphorylation-dependent interaction of τ3 with 14-3-3. The state of τ3 phosphorylation affects the mode of 14-3-3 binding and by this means might modify tau filament formation.Structured summaryMINT-7233358, MINT-7233372, MINT-7233384: 14-3-3 zeta (uniprotkb:P63104) and Tau 3 (uniprotkb:P10636-3) bind (MI:0407) by molecular sieving (MI:0071)MINT-7233323, MINT-7233334, MINT-7233346: Tau 3 (uniprotkb:P10636-3) and 14-3-3 zeta (uniprotkb:P63104) bind (MI:0407) by crosslinking studies (MI:0030)MINT-7233285, MINT-7233297, MINT-7233310: 14-3-3 zeta (uniprotkb:P63104) and Tau 3 (uniprotkb:P10636-3) bind (MI:0407) by comigration in non-denaturing gel electrophoresis (MI:0404

A core collection of common bean from the Iberian peninsula

11 páginas, 4 tablas.Characterization of crop germplasm from specific regions helps understand the patterns of genetic variation that facilitates further germplasm collection, characterization, management and their more efficient utilization in genetics, breeding and other studies. Common bean (Phaseolus vulgaris L.) is a traditional crop in the Iberian Peninsula (Spain and Portugal) where subsistence farmers have been growing and maintaining their own cultivars since their introductions from the Americas in the sixteenth century. Our objectives were to: (i) characterize diversity in the landraces collected from the Iberian Peninsula and (ii) form a core collection. Of 388 landraces from the major production regions characterized for 34quantitative and 13 qualitative characters, including morphological, agronomic and biochemical traits, 74.7% had an Andean origin, 16.8% a Mesoamerican origin and 8.4% had seed mixtures or were recombinants between the two gene pools. Landraces of indeterminate climbing growth habit Type IV(47.2%) and bush determinate Type I(26.4%) with large (52.9%) and medium(27.4%) seeds of white (38.8%) and cream(25.9%) colour were predominant. Similarly, the ‘T’ phaseolin pattern and common bean race Nueva Granada were the most frequent(51%). Some exceptionally large-seeded landraces of Andean (e.g., PHA-0917 with119 g 100-seed weight-1) and Mesoamerican (e.g., PHA-0399 with 66 g100-seed weight-1) were found. These and other possible recombinants between the two gene pools merit further investigation. Fifty two landraces (13%) were chosen to form a core collection representing the genetic diversity in the Iberian Peninsula.This study was made possible through fellowships from Diputación de Pontevedra and Xunta de Galicia (Spain) to Paula Rodiño.

Adjusting Water Processing Technology in the Function Water Quality of Lake Radoniqi

In different seasons the water of the lake "Radoniqi" showed changes in the water quality, such as increased turbidity, presenting an unpleasant odor or flavor. Aeration, flocculation, filtration and disinfection with chlorine failed to completely eliminate undesirable odor or flavor. The purpose of this paper is the adjustment of water treatment technologies based on physical-chemical and bacteriological characteristics of Lake Radoniqi water. The objectives of the study are to identify the physical-chemical and organoleptic parameters of water before and after treatment of water in the treatment plant, and adjustment of technologies in the function of unprocessed water quality. In this study were analyzed following water parameters, such as turbidity, smell, taste, pH value, potassium permanganate value, dissolved oxygen, iron, manganese, ammonia, nitrites, nitrates, phosphates, aluminum, etc. Water samples are tested in the physical-chemical laboratory with methods, such as jar-test method, organoleptic test, pH meters, conductivity, turbidity, spectrophotometric methods and classical methods of chemical analysis (volumetric method). Results of physical-chemical and organoleptic analysis of lake water help us to determine the water intake level of the lake as well as make a decision for the most appropriate technology for water treatment.Keywords: water, parameters, lake, methods, results

Invariant amino acids essential for decoding function of polypeptide release factor eRF1

In eukaryotic ribosome, the N domain of polypeptide release factor eRF1 is involved in decoding stop signals in mRNAs. However, structure of the decoding site remains obscure. Here, we specifically altered the stop codon recognition pattern of human eRF1 by point mutagenesis of the invariant Glu55 and Tyr125 residues in the N domain. The 3D structure of generated eRF1 mutants was not destabilized as demonstrated by calorimetric measurements and calculated free energy perturbations. In mutants, the UAG response was most profoundly and selectively affected. Surprisingly, Glu55Arg mutant completely retained its release activity. Substitution of the aromatic ring in position 125 reduced response toward all stop codons. This result demonstrates the critical importance of Tyr125 for maintenance of the intact structure of the eRF1 decoding site. The results also suggest that Tyr125 is implicated in recognition of the 3d stop codon position and probably forms an H-bond with Glu55. The data point to a pivotal role played by the YxCxxxF motif (positions 125–131) in purine discrimination of the stop codons. We speculate that eRF1 decoding site is formed by a 3D network of amino acids side chains

A numerical study of two different specimen fixtures for the modified compact tension test – their influence on concrete fracture parameters

The modified compact tension test (MCT) may represent a new test configuration for the performance of static and other kinds of fatigue tests on concrete-like materials. Core drilling can be employed to obtain specimens which are cylindrical in shape and have a standard diameter of 150 mm, this being appropriate for the determination of the residual life of structures. This contribution focuses on the evaluation of MCT specimen fracture behavior during static tests. Cracks evolution are simulated numerically using ATENA finite element (FE) software, while the results are represented as L-COD diagrams, i.e. load vs. crack opening displacement measured on the loading axis. After numerical calculations, the results for two different fixtures are compared and the advantages or drawbacks for each solution are discussed

Heavy Metals Accumulation by Aromatic Plant Salvia Officinalis Irrigated with Treated Wastewater

The use of wastewater for the irrigation of plants will contribute to the beneficial factors of plant growth, but it can damage human health because of the high concentration of toxic elements. The main goal of this research is to assess the concentration of some toxic heavy metals in the Salvia Officinalis plants after their harvest, which is irrigated with treated wastewater. Salvia Officinalis plants leaves are used in culinary and medicine. Sage plants are cultivated in an experiment using pots, in the greenhouse for 180 days. Treatments aim to assess a number of elements (Cd, Cr, Cu, Pb, Ni and Zn), that are accumulated in plants irrigated with treated and untreated sewage waters. The concentration of these heavy metals in both treated and untreated sewage waters are below the maximum permissible level in irrigation waters set by the World Health Organization (WHO). The development of plants and the content of heavy metal in their tissues are estimated. The results show that heavy metals content varied from spot to spot, plant to plant, and also in different parts of each plant. This study confirms that domestic sewage can effectively increase water resources for irrigation but the need for continuous monitoring of the concentration of toxic elements in soil, plants, and water, still exists. It is required that plants should be checked for contaminant before processing them for pharmaceutical purposes or for human consumption.Keywords: Treated Wastewater, Irrigation, Heavy Metals, Salvia Officinalis.
