Coincidence Points for Mappings under Generalized Contraction

In this paper we establish some results on the existence of coincidence and fixed points for multi-valued and single valued mappings extending the result of Feng and Liu [2] and Liu et.al [5]. It is also proved with counter example that our results generalize and extend some well known results. Key Words: common fixed point, Coincidence point, multi-valued mappings

Damaging Similarities in Highly Skilled Signature Simulations - Their Detection and Authorship

Questioned document examination is a highly specialized and challenging field of study, because of the variety and complexity of problems that are referred to document examiners. Detection and identification of practiced simulated forgeries is an area of forensic science which requires the professional skill, capability and acumen of an examiner, every time he (or she) is called upon to examine and report a case of this nature. This is because firstly, the practiced simulations bear a striking semblance to the copied model and usually contains the handwriting features of the writers, the real person as well as the forger, though in varying degrees.Secondly, the skilled forger rarely leaves his own imprint in the forgery he committed. Most authorities on the subject have advised that the identification of authorship, in such cases, may be considered as an exception rather than the rule. Besides discussing and reviewing the work done in this regard, the authors have also presented and illustrated an intricate case study where the authorship of simulated signatures could be associated with the known handwriting of the suspected forge

Low-density series expansions for directed percolation I: A new efficient algorithm with applications to the square lattice

A new algorithm for the derivation of low-density series for percolation on directed lattices is introduced and applied to the square lattice bond and site problems. Numerical evidence shows that the computational complexity grows exponentially, but with a growth factor \lambda < \protect{\sqrt[8]{2}}, which is much smaller than the growth factor \lambda = \protect{\sqrt[4]{2}} of the previous best algorithm. For bond (site) percolation on the directed square lattice the series has been extended to order 171 (158). Analysis of the series yields sharper estimates of the critical points and exponents.Comment: 20 pages, 8 figures (3 of them > 1Mb

Fixed and coincidence point theorems on partial metric spaces with an application

The aim of this paper is to investigate some fixed and co-incidence point theorems in complete, orbitally complete and (T, f)-orbitally complete partial metric spaces under the generalized contractive type conditions of mappings. Moreover, our results generalize and extend the several obtained results in the literature. Additionally some non-trivial examples are demonstrated, and an application has discussed to integral equations

Učinak ricinoleične kiseline iz ricinusova ulja na proizvodna svojstva i hemato-biokemijski profil krava pasmine Kankrej u laktaciji

The aim of the present study was to evaluate the effects of dietary ricinoleic acid from castor oil on the milk yield, composition, fatty acid profile and haemato-biochemical profile in lactating Kankrej cows. Twenty lactating Kankrej cows were assigned to the following groups: control (CON), basal diet without any additive and treatment (RAS), basal diet with 2 g/animal/day of ricinoleic acid from castor oil. Dietary ricinoleic acid had no (P>0.05) effect on dry matter intake and feed efficiency. Milk yield (milk, 4% fat corrected milk and energy corrected milk) were not affected (P>0.05) by the feeding of ricinoleic acid. The milk composition showed no significant differences between the groups. A significantly (P0.05) in haemato-biochemical profile between the CON and RAS groups. It was concluded that supplementation of 2 g/animal/day ricinoleic acid from castor oil had no effect on milk yield, milk composition and haemato-biochemical profile. However, it increased the milk fat percentages of unsaturated fatty acids and polyunsaturated fatty acids, and decreased milk saturated fatty acids, without any adverse effect on the health status of the cows.Cilj istraživanja bio je procijeniti učinak ricinoleične kiseline iz ricinusova ulja na prinos mlijeka, kemijski sastav mlijeka, profil masnih kiselina u mlijeku te na hemato-biokemijski profil krava pasmine Kankrej u laktaciji. Ukupno 20 krava u laktaciji podijeljeno je u: kontrolnu skupinu (CON), skupinu koja je dobivala osnovnu hranu, bez dodataka i pokusnu skupinu (RAS), koja je dobivala osnovnu hranu i 2 g po životinji dnevno ricinoleične kiseline iz ricinusova ulja. Ricinoleična kiselina nije imala učinka (P>0,05) na unos suhe tvari i iskorištavanje hrane. Dodatak ricinoleične kiseline nije utjecao (P>0,05) na prinos mlijeka (mlijeko, obogaćeno mlijeko s 4 % masnoće i energijski obogaćeno mlijeko). Sastav mlijeka nije pokazao znakovite razlike među skupinama. Uočen je znakovito veći postotak C4:0, C6:0 i C8:0 u mlijeku u skupini RAS (P0,05) u hemato-biokemijskom profilu skupina CON i RAS. Zaključeno je da dodatak 2 g ricinoleične kiseline po životinji dnevno ne utječe na prinos i sastav mlijeka te hemato- biokemijski profil, međutim povećava postotak mliječne masti, nezasićenih masnih kiselina i višestruko nezasićenih masnih kiselina, a smanjuje postotak zasićenih masnih kiselina bez posljedica za zdravlje krava

Nanostructured Manganese Hexacyanidocobaltate(III) as Heterogeneous Catalyst for Solvent-Free Oxidation of Benzyl Alcohol

Manganese hexacyanidocobaltate(III) nanostructures have been synthesized using double decomposition method and characterized in terms of CHNS analysis, atomic absorption spectroscopy, thermal analysis, infrared spectral studies and transmission electron microscopic technique. The transmission electron microscopic image of the synthesized material showed that it is consisting of roughly spherical shaped particle with size range of 30-60 nm. The catalytic activity of the synthesized material was studied for the oxidation of benzyl alcohol, using H2O2 as oxidant, under solvent-free conditions. The characterization of the oxidation product of benzyl alcohol and its quantitative estimation was done using gas chromatography. The synthesized material was found to be an effective heterogeneous catalyst with a high selectivity towards benzaldehyde as the oxidation product. It showed 31% conversion of benzyl alcohol under the optimized conditions of various reaction parameters, namely, amount of catalyst, reaction temperature, benzyl alcohol to H2O2 molar ratio and the reaction time

Sequence Analysis of Novel Staphylococcus aureus Lineages from Wild and Captive Macaques

Staphylococcus aureus is a widespread and common opportunistic bacterium that can colonise or infect humans as well as a wide range of animals. There are a few studies of both methicillin-susceptible S. aureus (MSSA) and methicillin-resistant S. aureus (MRSA) isolated from monkeys, apes, and lemurs, indicating a presence of a number of poorly or unknown lineages of the pathogen. In order to obtain insight into staphylococcal diversity, we sequenced strains from wild and captive individuals of three macaque species (Macaca mulatta, M. assamensis, and M. sylvanus) using Nanopore and Illumina technologies. These strains were previously identified by microarray as poorly or unknown strains. Isolates of novel lineages ST4168, ST7687, ST7688, ST7689, ST7690, ST7691, ST7692, ST7693, ST7694, ST7695, ST7745, ST7746, ST7747, ST7748, ST7749, ST7750, ST7751, ST7752, ST7753, and ST7754 were sequenced and characterised for the first time. In addition, isolates belonging to ST2990, a lineage also observed in humans, and ST3268, a MRSA strain already known from macaques, were also included into the study. Mobile genetic elements, genomic islands, and carriage of prophages were analysed. There was no evidence for novel host-specific virulence factors. However, a conspicuously high rate of carriage of a pathogenicity island harbouring edinB and etD2/etE as well as a higher number of repeat units within the gene sasG (encoding an adhesion factor) than in human isolates were observed. None of the strains harboured the genes encoding Panton–Valentine leukocidin. In conclusion, wildlife including macaques may harbour an unappreciated diversity of S. aureus lineages that may be of clinical relevance for humans, livestock, or for wildlife conservation, given the declining state of many wildlife populations
