Criteria for evaluation of the existing school buildings registered in the rural settlements of the city of Nis have been formed, by defining the relevant parameters for evaluation from different ...aspects, such a conditions at location, functional-organizational and architectonic-engineering characteristics of the buildings. On the basis of the established criteria and the formed data base, which consists of the systematized documentation about the existing buildings, the research that had to discover the extent of presence of certain organizational units in the existing village school buildings and the ways of their functioning was conducted. The results of this research have been presented in this paper.
Kriterijumi za evaluaciju postojeceg fonda seoskih skolskih zgrada evidentiranih u ruralnim naseljima na podrucju grada Nisa, formirani su definisanjem relevantnih parametara za vrednovanje sa aspekta uslova lokacije, funkcionalno-organizacionih i arhitektonsko-gradjevinskih karakteristika objekata. Na osnovu uspostavljenih kriterijuma i oformljene baze podataka, koju cini sistematizovana dokumentaciona gradja o postojecem gradjevinskom fondu, obavljeno je istrazivanje u pogledu zastupljenosti pojedinih organizacionih celina u postojecim seoskim skolskim zgradama i u pogledu nacina njihovog funkcionisanja. Rezultati tog istrazivanja prezentirani su u ovom radu.
Ripening inhibitor (rin) gene is a spontaneous recessive mutant which changes fruit ripening aspects (most important synthesis of carotene, especially lycopene). It also delays fruit senescence. ...Tomato is a vegetable crop with specific maturing climax (pik). Tomato genotypes homozygote for rin gene does not have this maturing climax, so the ethyl-ene production and red, lycopene colour does not appear. In order to research the maturing process material from the final tomato selection cycle we used: pure line S-49 (genetic constitution u/u, with uniform ripening), line hom 4 (rin/rin, homozygote with ripening inhibitor) and hybrid combination 449 Fl (u/rin, heterozygote for ripening inhibitor). Fruits with uniform ripening and hybrids ripened simultaneously, while homozygote with rin gene did not ripe at all. Ethylene stimulates the appearance of yellow colour in rin fruits and the lycopene production. After treatment with ETEPHONE (0.1%) (Ethylene) fruits with uniform ripening, senescence more quickly, while hybrids senescence slowly. Rin homozygotes did not change colors, but the fruits senescence more quickly comparing to control. Ethylene treatment speeded the maturing and senescence process in tomato fruits. Extended maturing process as a result influence of rin gene, makes the new created hybrids a late maturing ones. On the other hand, the firmness of fruits is improved as well as the "shelf life", which enables longer transportation and storing, coordinated maturing according to market demands. The aim was to research the maturing according to market demands. The aim was to research the maturing process of rin heteroyzgote, and the reaction of some genotypes to treatment with RT-REL (Ethzlene) in order to decrease extremely late maturing.
Inhibitor sazrevanja (rin) gen predstavlja spontani recesivni mutant koji menja aspekte sazrevanja ploda, a najznacajniji sintezu karotenoida posebno likopina. Takodje usporava starenje plodova. Paradajz spada u biljke koje imaju karakteristicni vrhunac (pik) prilikom sazrevanja plodova. Genotipovi paradajza homozigoti za rin gen nemaju ovaj vrhunac u sazrevanju, tako da izostaje produkcija etilena i crvena Likopinska boja. Za potrebe ispitivanja procesa sazrevanja, korisceni su materijali iz zavrsnih ciklusa selekcije paradajza: cista linija S-49 (genetske konstitucije +/+, uniformnog sazrevanja), linija hom 4 (rin/rin, homozigot za ripening inhibitor) i hibridna kombinacija 449 FI (+/rin. heterozigot za ripening inhibitor). Plodovi sa uniformnim sazrevanjem i hibridi sazrevali su isto vreme dok homozigoti za rin gene nisu sazrevali. Etilen stimulise razvoj zute boje u rin plodovima stimulise pojavu likopina Posle tretmana etephoneom (0.1%) (etilen) od plodova sa uniformnim sazrevanjem utvrdjeno je brze propadanje kod hibrida je utvrdjen duzi period izdrzljivosti, odnosno sporije propadanje. Kod rin homozigota nije dobijena promena boje, ali su plodovi propadali ubrzanije u odnosu na netretiranu varijantu. Tretman etilenom ubrzavao je procese sazrevanja, ali i starenja plodova paradajza. Prolongacija sazrevanja kao posledica delovanja rin gena svrstava dobijene hibride u kasniju grupu sazrevanja, cime se gubi na ranostasnosti. S druge. strane dobija se na cvrstini plodova i na "shef life", koji omogucava duzi transport i skladistenje, a ukoliko se ubiraju zeleni plodovi i na koordiniranom sazrevanju prema potrebama trzista. Cilj ispitivanja je bio da se utvrdi ponasanje u sazrevanje rin heterozigota. kao i reakcija genotipova na tretman etrelom u cilju ublazavanja ekstremnih vrednosti kasnog sazrevanja.
Missing information in image can be recovered by using the principles of lower sample rate methods, such as Compressive Sensing. This method can, at the same time, recover the missing information in ...the signal and do the compression of the original data. Lowering the sample rate is especially suitable for natural images in applications where minor visually loss of fidelity is acceptable. The goal is to achieve a substantial reduction in bit rate and image size. In this paper we analyze the performance and quality of Compressive Sensing approach applied on images captured by the TrapView automated camera station for pest detection. The reconstruction at the decoder side, if only small number of image samples is available, is tested in the paper. This is done with the goal to test different approach in image capturing - acquisition of only part of digital data, and then the reconstruction of the uncaptured/missing part, in order to obtain the original signal. This leads to decreasing the bit rate and transferred data volume through the mobile network, from the station to the TrapView cloud centre. It is shown that CS can provide a good quality image reconstruction with significantly reduced number of samples. The theory is tested using real images, obtained by the TrapView camera.
First pod height is an important trait, especially for snap bean since it enables the mechanical harvesting. Cultivars with low first pod height may be cut, damaged or not harvested by mechanical ...harvesting. In our investigation six different snap bean genotypes were used for examination of the first pod height and diallel analysis. The result was obtained by using method 2 model 1 GRIFFING (1956) for analysis of combining abilities. The mode of inheritance was different, as the results showed - from intermediate to super dominance, for both generations (F1 and F2). Analysis of combining abilities showed both influence of additive and dominant gene effects. Combination Sumadinka x Zora is suitable for further breeding for first pod height.
Visina formiranja prve mahune je vazna sortna osobina od koje zavisi mogucnost mehanizovanog ubiranja useva boranije, sto je osnova proizvodnje ove biljne vrste za prehrambenu i preradjivacku industriju. Sorte koje nisko formiraju prve mahune, pri mehanizovanoj zetvi, usled nedovoljne visine, bivaju ostecene. U ispitivanje je ukljuceno 6 divergentnih roditeljskih linija za proces selekcije na povecanje visine formiranja prve mahune. Za utvrdjivanje opstih (OKS) i posebnih kombinacionih sposobnosti (PKS) pojedinih linija koriscen je matematicki metod 2, model 1 GRIFING (1956). Vrednosti parametara su utvrdjivane u F1 i F2 generaciji potomstva. Analiza kombinacionih sposobnosti pokazuje delovanje aditivnih i dominantnih genskih efekata. Sumadinka x Zorka predstavljaju najbolju kombinaciju za dalji proces selekcije na povecanje visine prve mahune.
Recently a high-resolution HLA and SNP map was defined and the analysis provided informative tag SNPs that capture much of the common variation in the MHC region. This concept enables detection of ...smaller number of SNPs, making it “surrogate” markers for haplotype associated with certain disease. The SNP rs3135388 was proposed as a tagging SNP for DRB1⁎1501/DQB1⁎0602 alleles, associated with MS. The aim of the study was to investigate the HLA rs3135388 genotypes in association with MS in patients from Serbia.
Two hundred sixty nine consecutive patients from Serbia with relapse-remitting and secondary progressive MS were recruited for the study. Genomic DNA was isolated from peripheral blood cells. We designed the TaqMan assay for high-throughput genotyping of HLA rs3135388 on 7500 Real-Time PCR System.
We found significantly higher frequency of rs3135388 A allele carriers in MS patients compared to controls (
p
<
0.001,
χ
2). In our population the carriers of one A allele had adjusted OR 2.09 (95% CI 1.41–3.09,
p
<
0.001) for MS susceptibility.
We assessed significant association of rs3135388 A allele carriership with MS in patients from Serbia. This HLA-DRB1⁎1501 “surrogate” marker is useful in association studies in MS.
Percutaneous nephrostomy and ureteral stenting are temporary treatments for the upper urinary tract obstruction. The aim of this study was to evaluate the efficacy of these two methods by comparing ...complications, placement success, urinary symptoms, urine culture analyses prior to derivation placement and derivation removal and success of stone elimination after extracorporeal shock wave lithotripsy (ESWL). This prospective study included 157 patients with supravesical obstruction caused by ureteral stones. Eighty-one patients underwent percutaneus nephrostomy, and JJ stent was inserted in seventy-six (76) patients. After resolving the obstruction, ESWL was performed in all patients. There were no statistically significant differences in success of the urinary derivation placement, the urine culture results before and after placement and success of ESWL treatment between the two studied groups (p>0.05). Urinary symptoms (dysuria, hematuria, urinary urgency, frequent urination during the day) were significantly more present in patients with a JJ stent and this difference was statistically significant for each symptom (p<0.001). Major complications were verified in 2 (2.46%) patients with PCN catheter, and in 7 (9.2%) patients in the group with the JJ stent. Minor complications were significantly more frequent in the group with the JJ stent compared to the group with PCN catheter (28.39% vs 60.52%, p<0.001). Percutaneous nephrostomy and JJ stenting are optimal methods for temporary treatment of supravesical obstruction caused by ureteral stones, with similar incidence of the following complications, except for the pain, which dominates in patients with the JJ stent. Urinary symptoms and asymptomatic bacteriuria are more common in patients with the JJ stent. If the ESWL treatment of ureteral stone is performed after urinary derivation placement, we can expect greater success in patients with the JJ stent.
Polarization curves of the anodic dissolution reaction of zinc were determined in EDTA solutions of different total molar concentrations (0.05, 0.10, 0.15 and 0.20 mol dm-3), the pH values of which ...were systematically varied (pH 3.0 10.0). The Tafel slopes of the anodic polarization curves are close to 40 mV dec-1 at lower current densities (10-5 5x10-4 A cm-2), while at higher current densities (5x10-4 10-2 A cm-2) the slopes are in the range of 60 120 mV dec-1. The order of the anodic reaction determined from the anodic polarization curves at lower current densities are: z+ (H+) ~ 1/2 for pH < 8 and z+(H+) ~ 1 for pH > 8, while z+(H4Y) ~ 1 for all pH values of the examined EDTA solutions. On the basis of these results, two mechanisms of the zinc anodic dissolution reaction are proposed: at pH < 8 and at pH > 8. In both cases the relevant EDTA species directly participate as reactants in the anodic reaction. The dependences of the corrosion potential on pH and on total molar EDTA concentration indicate that the relevant EDTA species take part as reactants in both the cathodic (hydrogen evolution) and anodic (zinc dissolution) reactions of the zinc corrosion process.
