Opis:: The publication of the new European Union Basic Safety Standards represents a remarkable milestone in the fi eld of radiological protection in terms of adding radon exposure to this framework. Therefore, the coming years will bring the need to measure radon not only in the workplaces but also in the living spaces as a direct outcome of the application of the new EU Directive. So, the importance of having reliable instruments is evident and interlaboratory exercises are becoming more and more popular. However, most of them are carried out under constant conditions of meteorological variables. We present in this paper a facility to broaden the interlaboratory comparisons further by adding the study of radon exposures under real conditions of changes in climatic parameters. In addition, the facility has the possibility to verify the response of radon monitors when the radon concentration changes several orders of magnitude in a short period of time. Our work shows some results of one of the interlaboratory exercises carried out in the premises, where the radon levels were rather homogeneous in the testing room.

Opis:: The incoherent scattering of electrons by a layer adsorbed at a single crystal surface is determined by the topological correlations of elements forming the adsorbed layer. The model for the description of atoms or molecules adsorbed on the surface is formulated in terms of occupation operators which are expressed in terms of pseudospin operators with a given spin value. The correlations can be determined by the fluctuation dissipation theorem in connection with the susceptibility or given directly by means of the Green functions properly chosen. An example of the topological or chemical disorder of two components is considered in detail. The calculations of the topological correlations allow us to find the incoherent scattering amplitude as a function of the surface coverage which can be experimentally detected.

Opis:: The incohorent scattering of electrons by layer adsorbed at a single crystal surface is determined by the Fourier transform of correlation functions of elements forming this layer. The model of the description of atoms or molecules adsorbed on the surface is formulated by the occupation operators which are represented by the pseudospin operators. The calculations of the correlation functions are performed by means of methods which consider a given pair of elements embedded in the effective field of remaining elements of the system while the interaction between the elements of the pair are taken in its exact form. Two approaches are presented here, i.e. the cumulant average and constant coupling approximations, and the case of binary chemisorption is considered in detail. The problem of the correlation symmetry is also discussed.

Opis:: This paper addresses the design of a state estimation and sensor fault detection, isolation and fault estimation observer for descriptor-linear parameter varying (D-LPV) systems. In contrast to where the scheduling functions depend on some measurable time varying state, the proposed method considers the scheduling function depending on an unmeasurable state vector. In order to isolate, detect and estimate sensor faults, an augmented system is constructed by considering faults to be auxiliary state vectors. An unknown input LPV observer is designed to estimate simultaneously system states and faults. Sufficient conditions to guarantee stability and robustness against the uncertainty provided by the unmeasurable scheduling functions and the influence of disturbances are synthesized via a linear matrix inequality (LMI) formulation by considering H∞ and Lyapunov approaches. The performances of the proposed method are illustrated through the application to an anaerobic bioreactor model.

Opis:: The use of SBAS corrections for navigation, in both coastal waters and inland waterways, has already brought the attention of many European authorities, which are interested in its potential to complement/replace their DGPS radio beacon networks. The European GNSS Agency (GSA) has an active long-term trajectory working to foster the EGNOS adoption in maritime through the launch of several actions whose results will pave the way for the provision of maritime EGNOS services. In this line, GSA awarded the consortium ALG-Indra, ESSP and Alberding with the Specific Contract GSA/OP/07/13/SC24 ‘Support to Maritime Service Providers for the transmission of EGNOS corrections via IALA beacons and AIS/VDES stations’. The main objective of this Specific Contract is to demonstrate the operational performance of the transmission of EGNOS corrections converted to Differential GPS corrections over the existing transmission infrastructure (AIS base stations/IALA beacons) in the Maritime and Inland Waterways (IWW) domains, while providing a detailed cost benefit analysis of the solutions proposed. This service may complement the current GNSS augmentation services exploiting synergies and benefiting from the current infrastructure and standards, facilitating the adoption of EGNOS by maritime and inland waterways authorities. Furthermore, the service has no impact at user level since the DGNSS corrections are transmitted over the existing infrastructure, in the same format and implementing the same integrity mechanisms required for traditional IALA beacons ([1]). This project will allow the maritime and IWW service providers to have a clear understanding about the technical, operational and economic feasibility of the transmission of EGNOS corrections via IALA beacons and AIS/VDES stations.

Opis:: Notoungulates represent the most taxonomically diverse and temporally and geographically widespread group among South American native ungulates. Here, we analyze anatomical and systematic aspects of proximal tarsal bones recovered from the Lower and Upper Lumbrera formations (middle and late middle Eocene) in northwestern Argentina. We provide detailed descriptions, comparisons, and infer foot stances and range of movements for the taxa implicated. Material studied includes astragali belonging to the oldfieldthomasiid Colbertia lumbrerense (Lower Lumbrera Formation), a set of proximal tarsals referred as Typotheria indet. (Lower Lumbrera Formation), and tarsals (also including navicular and cuboid) of the informal taxon “Campanorco inauguralis” (Upper Lumbrera Formation). The comparison of the tarsals of Colbertia lumbrerense (middle Eocene of Argentina) with Colbertia magellanica (early Eocene of Brazil) reveals several differences including variations on the development and arrangement of articular facets, and the size of the dorsal astragalar foramen in the Argentinean species. The specimen of Typotheria indet. shows morphological affinities with basal interatheriid taxa. However, its larger size contrasting with the overall small body sizes of Eocene interatheriids precludes an indisputable taxonomic assignment. Concerning “Campanorco inauguralis”, our observations indicate that there is no morphological evidence for a close phylogenetic relationship with Mesotheriidae. It presents a “reversed alternating tarsus” condition, which is also observed in Leontiniidae, “Notohippidae”, Toxodontidae, and some typotherians. However, the spectrum of singularities exhibited by this form precludes the assessment of its relationships in the context of the Paleogene radiation of Typotheria and it is necessary to extend the comparison to Eocene notoungulates. Finally, in a morphofunctional context a plantigrade foot posture is inferred for the specimens here reported. These observations have the potential to provide functional proxies for paleoecological reconstructions to be applied to the study of the early radiation of these notoungulate faunas.

Opis:: The overall aims of this project are to assess the safety and immunogenicity of the Schistosoma japonicum vaccine paramyosin among water buffaloes residing in endemic areas. The study was conducted in four villages in Leyte, the Philippines, an area highly endemic for schistosomiasis japonica. One hundred and fifteen (N=115) animals provided baseline stool samples for coprologic examination, with preliminary results using FLOTAC showing a 10% prevalence of schistosomiasis. Forty-nine (N=49) animals consented to treatment with 25 mg/kg Praziquantel, and 40, 36 and 32 animals consented to the first, second and third dose of the paramyosin vaccine, respectively. The safety trial involved the first 20 animals and included skin testing, vaccination, anaphylaxis monitoring, as well as hematology and serum chemistry analysis. Skin tests revealed that only three out of 20 animals exhibited redness at the injection site, with none greater than 1 cm. None of the animals exhibited anaphylaxis, and all hematology and serum chemistry markers were within normal range or were similar to pre-vaccination levels. None of the 40 animals administered with the first dose exhibited anaphylaxis, nor any of the subsequent vaccine doses. Immunogenicity assessment of sera collected prior to every vaccination and one month after the last dose showed that the paramyosin vaccine induced robust antibody responses to all animals, as assessed by ELISA. The cytokine levels of whole blood culture supernatants will be further assessed. Our findings demonstrate that the S. japonicum paramyosin vaccine is a safe, well-tolerated and immunogenic treatment among water buffalos residing in endemic areas.

Opis:: In maize plant breeding aimed at producing a hybrid, it is necessary to characterize the parents and hybrids by their agronomic aspects and grain quality so that the processing industry may offer consumers a quality product and also improve its efficiency. This study evaluated the viscoelastic parameters of masa and the chemical and texture properties of tortillas obtained from parent lines (M-54, M55, and CML-242), two single crosses (M54xM55 and M55xM54), and one hybrid (H-70). The morpho- logy of the maize grains and tortillas was analyzed using scanning electron microscopy. The firmness of masa obtained from CML-242 and H-70 maize was higher than that from the other maize genotypes. M-54 tortillas showed the lowest crude fiber content. Otherwise, tortillas obtained from the M55xM54 hard grain had the lowest fat content and extensibility, while H-70 tortillas showed an intermediate breaking point and extensibility. M-54 and M54xM55 tortillas were softer due to their more swollen starch granules. In contrast, rigid tortillas were obtained from CML-242 and H-70. Grain hardness causes different morphology in starch and tortilla of maize genotypes. However, grain hardness did not influence the characteristics of texture in tortillas.

androgen depravation therapy
triptorelin
Opis:: Triptorelin as the luteinizing hormone releasing hormone (LHRH) analogue has its own place among other available forms of androgen-depravation therapy (ADT) of locally advanced and metastatic prostate cancer (PCa). Nowadays, in times of development of new therapies in castration-resistant PCa, ADT remains the back bone therapy, which may be supplemented with one of novel drugs. The results of basic research indicate, that apart from the main mechanism of action based on lowering a testosterone concentration to the castration level, triptorelin may have a direct inhibitory effect on tumor cells. Formulations of tryptorelin are available to administer as 1-month, 3-months and 6-months sustained-release forms that may be given intramuscularly or subcutaneously. Constant concentration of triptoreline is maintained by using special microspheres in drug production. Pharmacokinetic and pharmacodynamic properties of particular forms were extensively tested, which allows for safe usage and retain of predictable and high efficacy. Indicators of effective ADT are fast reduction and maintenance of the state of castration. This phenomenon translates into a decrease of the prostate-specific antigen and longer survival. Triptorelin successfully meets these objectives based on a number of phase I–III studies. There is a noticeable lack of comparative studies on effectiveness of particular ADT forms. This may stem from an assumption, that all LHRH analogues demonstrate similar effectiveness because of the class effect. However, some evidence highlight significant differences in efficacy among these drugs. Triptorelin compares especially favourably, particularly as a drug reducing the testosterone level to the lower recommended values (< 20 ng/dl). Side effect profile during the therapy with triptorelin is largely the result of inhibition of the hypothalamic- pituitary-testicular axis. Hormonal disturbances linked to hipoandrogenism cause changes in lipid metabolism and glucose tolerance, which may influence the cardiovascular risk. This article is a review of key reports regarding triptorelin and a summary of the role that triptorelin plays in contemporary ADT in advanced PCa.
