Scarabidae - prelazni domaćini za macracanthorhynchus hirudinaceus

Macracanthorhynchus hirudinaceus infestation is parasitosis caused by Macracanthorhynchus hirudinaceus Adult forms parasite in small intestine of swine. Development of parasite is happening through intermediate hosts - coleopteras from Scarabaeidae family (Melolontha vulgaris, Cetonia aurata, Polyphilla fullo, Anomalia vitis etc). Infection begins when swines ingest infected coleopteras. Macracanthorhynchus hirudinaceus infestation is encountered in swines in extensive breeding, as well as in wild boars.Makrakantorinhoza je parazitoza uzrokovana akantocefalom Macracanthorhynchus hirudinaceus. Odrasli paraziti parazitiraju u tankim crevima svinja. Razvoj parazita se odvija preko prelaznih domaćina - koleoptera iz familije Scarabidae (Melolontha vulgaris, Cetonia aurata, Polyphilla fullo, Anomalia vitis i dr). Infekcija nastaje kada svinje pojedu zaražene koleoptere. Makrakantorinhoza se sreće kod svinja u ekstenzivnom držanju, kao i kod divqih svinja

Identity Provider Deployment Based on Container Technology

Identity Providers are an integral part of Identity Federations. Many different and complex technologies are needed to create an Identity Provider. In order to be able to fully utilize all the benefits of Identity Federations, adequate hardware resources are needed for Identity Provider deployment. Containers address the complexity and resources issues, while enabling faster deployment and keeping the functionalities and core concepts intact at the same time. Containers cannot be perceived as a replacement for virtual machines or bare metal servers, as they are meant to co-exist and have already found a wide range of use cases. This paper proposes using containers for easier implementation of Identity Providers, while lowering resource usage and complexity imposed by deployment requirements

Upper limits for a narrow resonance in the reaction p + p -> K^+ + (Lambda p)

The reaction pp -> K^+ + (Lambda p) has been measured at T_p = 1.953 GeV and \Theta = 0 deg with a high missing mass resolution in order to study the Lambda p final state interaction. Narrow S = -1 resonances predicted by bag model calculations are not visible in the missing mass spectrum. Small structures observed in a previous experiment are not confirmed. Upper limits for the production cross section of a narrow resonance are deduced for missing masses between 2058 and 2105 MeV/c^2.Comment: 8 pages, 5 figure

Cross section of the pp→K+Σ+npp\to K^+\Sigma^+n reaction close to threshold

We have measured inclusive data on $K^+$-meson production in $pp$ collisions at COSY J\"ulich close to the hyperon production threshold and determined the hyperon-nucleon invariant mass spectra. The spectra were decomposed into three parts: $\Lambda p$, $\Sigma^0p$ and $\Sigma^+n$. The cross section for the $\Sigma^+n$ channel was found to be much smaller than a previous measurement in that excess energy region. The data together with previous results at higher energies are compatible with a phase space dependence.Comment: accepted by Phys. lett. B some typos correcte

Detailed comparison of the pp -> \pi^+pn and pp -> \pi^+d reactions at 951 MeV

The positively charged pions produced in proton-proton collisions at a beam momentum of 1640 MeV/c were measured in the forward direction with a high resolution magnetic spectrograph. The missing mass distribution shows the bound state (deuteron) clearly separated from the $pn$ continuum. Despite the very good resolution, there is no evidence for any significant production of the $pn$ system in the spin-singlet state. However, the $\sigma(pp\to \pi^+pn)/\sigma(pp\to \pi^+d)$ cross section ratio is about twice as large as that predicted from $S$-wave final-state-interaction theory and it is suggested that this is due to $D$-state effects in the $pn$ system.Comment: 8 pages, 3 figure

Upotreba api-fito terapije u suzbijanju subkliničkih mastitisa muznih krava

Production of high quality milk, milk containing low number of bacteria (several thousand to lt 141 000 cells/ml of milk) and low number of somatic cells count (SČ), is the target of Program of control and prevention of mastitis in dairy cows. Program of mastitis control must provide diagnostic tests for evaluation of udder infections by enviromental microorganizams and prevention of new intramammarian infections (IMI). The evidence is presented that longterm, intensive program of teat désinfection after milking and therapy of dryed cows are procedures which are enabling significant decrease of SČ and number of bacteria in 1 ml of milk. Clinical changes of udder are offtenly caused by Corynebacterium bovis, Streptococcus sp. and Staphylococcus sp. which are also responsible for increasment of SČ and IMI cases. Knowing that most of mastitisies are subclinical by character, than it is understandable that various IMI of dairy cows are appearing after usage of the various antiseptics. We have been using accessory remedy for dry milking VETER-D, for prevention of sub-clinical mastitisies, "dry" milking and evaluation of IMI spreadness in udder health ma-nagment program, on 403 dairy cows.Cilj programa i kontrole i suzbijanja mastitisa kod muznih krava je proizvodnja mleka visokog kvaliteta, tj. mleka koje će sadržati mali broj bakterija (od nekoliko hiljada do = 141 000 ćelija/ml mleka) i somatskih ćelija. Program kontrole mastitisa trebalo bi da ima kontrolu infekcija vimena sa organizmima sredine i efikasan sistem praćenja i sprečavanja novih intramamarnih infekcija vimena (MI). Postoje dokazi da dugoročni intenzivni programi dezinfekcije sisa posle muže i terapija zasušenih krava mogu izrazito da smanje broj SČ i bakterija u 1 ml mleka. Kliničke promene na vimenu najčešće izazivaju Corynebacterium bovis, streptokoke i stafiloke i to su faktori koji najviše povećavaju SČ i intramamarne infekcije. Budući daje većina mastitisa subklinička, postoji različit broj intramamarnih infekcija (IMI) vimena muznih krava posle dezinfekcije sisa sa različitim antisepticima. Mi smo upotrbljavaîi pomoćno lekovito sredstvo VETER-D za suzbijanje subkliniČkih mastitisa, "suvu" mužu i ispitivanje rasprostranjenosti IMI u menadžerskom programu zdravlja vimena, na 403 krave

Study of the p+6\bm{p+^6}Li→η+7\bm{\to\eta+^7}Be reaction 11.3 MeV above threshold

The cross section for the reaction $p+^6\text{Li}\to\eta+^7\text{Be}$ was measured at an excess energy of 11.28 MeV above threshold by detecting the recoiling $^7$Be nuclei. A dedicated set of focal plane detectors was built for the magnetic spectrograph Big Karl and was used for identification and four momentum measurement of the $^7$Be. A differential cross section of $\frac{d\sigma}{d\Omega}=(0.69\pm{0.20}\text{(stat.)}\pm 0.20\text{(syst.)})\text{nb/sr}$ for the ground state plus the 1/2$^-$ was measured. The result is compared to model calculations.Comment: accepted by Phys. Rev. C as rapid communicatio

Search for η\eta-mesic nuclei in recoil-free transfer reaction

We have studied the reaction $p+{^{27}Al}\to {^3{He}}+p+\pi^-+X$ at recoil-free kinematics. An $\eta$ meson possibly produced in this reaction would be thus almost at rest in the laboratory system and could therefore be bound with high probability, if nuclear $\eta$ states exist. The decay of such a state through the $N^*(1535)$ resonance would lead to a proton-$\pi^-$ pair emitted in opposite directions. For these conditions we find some indication of such a bound state. An upper limit of $\approx$ 0.5 nb is found.Comment: 3 figure

A precision determination of the mass of the η\eta meson

Several processes of meson production in proton-deuteron collisions have been measured simultaneously using a calibrated magnetic spectrograph. Among these processes, the $\eta$ meson is seen clearly as a sharp missing--mass peak on a slowly varying background in the $p+d\to ^3\textrm{He} +X$ reaction. Knowing the kinematics of the other reactions with well determined masses, it is possible to deduce a precise mass for the $\eta$ meson. The final result, $m(\eta)=547.311\pm 0.028 \textrm{(stat)} \pm 0.032 \textrm{(syst) MeV/c}^2$, is significantly lower than that found by the recent NA48 measurement, though it is consistent with values obtained in earlier counter experiments.Comment: 10 pages, 6 figures, Fig. 3 change

Cross Section and Tensor Analysing Power of the d⃗d→ηα\vec{d}d\to \eta\alpha Reaction Near Threshold

The angular distributions of the unpolarised differential cross section and tensor analysing power $A_{xx}$ of the $\vec{d}d\to\alpha \eta$ reaction have been measured at an excess energy of 16.6 MeV. The ambiguities in the partial-wave description of these data are made explicit by using the invariant amplitude decomposition. This allows the magnitude of the s-wave amplitude to be extracted and compared with results published at lower energies. In this way, firmer bounds could be obtained on the scattering length of the $\eta \alpha$ system. The results do not, however, unambiguously prove the existence of a quasi-bound $\eta \alpha$ state.Comment: 20 pages, 11 figure
