AbstractThe susceptibility of marine bacterial communities to copper pyrithione (CuPT2), zinc pyrithione (ZnPT2) and their degradation product is described and toxicities of these relatively new antifouling biocides compared with those of their harmful organotin (OT) predecessors, tributyltin (TBT) and triphenyltin (TPT). These biocides were added to agar at concentrations of 0, 0.01, 0.1, 1 and 10 mg l−1and coastal seawater including indigenous bacteria added to each batch of agar solution. The number of bacterial colony forming units (CFU) was measured after 7 days culture. Relative CFU (as a percentage of control) was more than 80% at a concentration of 0.01 mg l−1of each compound, except for TBT. Relative CFU decreased as a function of dose of each biocide, although concentration-dependent changes in rate of CFU were relatively low during exposure to degradation products of CuPT2and ZnPT2, pyridineN-oxide (PO) and pyridine-2-sulphonic acid (PSA). Based on comparisons of EC50, TBT was the most bacterio-toxic of the tested compounds (0.2 mg l−1), marginally more so than CuPT2(0.3 mg l−1). Interestingly, EC50values of degradation products of CuPT2and ZnPT2, 2-mercaptopyridineN-oxide (HPT) and 2,2′-dithio-bispyridineN-oxide (PT2) were 0.8 and 0.5 mg l−1, respectively, lower than that of the parent chemical, ZnPT2(1.4 mg l−1). The EC50of PT2was also lower than that of TPT (0.7 mg l−1), implying higher toxicity. Given the overlapping toxicity ranges, these results suggest that marine bacterial communities experience comparably high susceptibility to metal PTs and OTs during their life history.

ABSTRACTAs linseed oil ages, hydrolysis and oxidation produce acid groups on the polymer chain that may lead to ionomeric behavior. The effect of these changes is difficult to determine in old paints because of the lack of records of environmental and treatment histories that can alter the physical properties significantly. A series of paints were made that have chemical properties similar to those of aged paints and that mimic old paints. Their properties seem to show flexibility as well as coherency but low strength and a high susceptibility to solvents.

В статье исследованы подсистемы управления наукоёмким предприятием с позиций методологии и процесса управления. Отражены результаты исследования, включающие обоснование введения в научный оборот понятия «управление развитием наукоёмкого предприятия», под которым следует понимать управленческие воздействия на наукоёмкое предприятие как организационную систему, направленные на развитие отдельных подсистем и элементов, их взаимосвязей для качественного роста организационных характеристик и коммерциализацию производственного освоения результатов НИОКР. Концептуализирована организационно-экономическая сущность наукоёмких предприятий, предполагающая формирование научно-производственных отношений, обуславливающая их идентификацию как экономических субъектов с высокими инновационными свойствами и высокой восприимчивостью к состояниям внешней среды. The article examines the subsystems of management of a knowledge-intensive enterprise from the standpoint of the methodology and management process. The results of the study are reflected, including the rationale for the introduction into scientific circulation of the concept of «management of the development of a knowledge-intensive enterprise», which should be understood as managerial influences on a knowledge-intensive enterprise as an organizational system aimed at the development of individual subsystems and elements, their interconnections for the qualitative growth of organizational characteristics and commercialization of production development R&D results. The organizational and economic essence of science-intensive enterprises is conceptualized, which implies the formation of scientific and industrial relations, which determines their identification as economic entities with high innovative properties and high susceptibility to conditions of the external environment.

Several reports have related Legionella pneumophila with pneumonia in renal transplant patients, however this association has not been systematically documented in Brazil. Therefore this paper reports the incidence, by serologycal assays, of Legionella pneumophila serogroup 1 in these patients during a five year period. For this purpose sera from blood samples of 70 hospitalized patients with pneumonia from the Renal Transplant Unit of Hospital das Clinicas, FMUSP collected at the acute and convalescent phase of infection were submitted to indirect immunofluorescence assay (IFA) to demonstrate anti-Legionella pneumophila serogroup 1 antibodies. Of these 70 patients studied during the period of 1988 to 1993,18 (25.71 %) had significant rises in specific antibody titers for Legionella pneumophila serogroup 1. Incidence was interrupted following Hospital water decontamination procedures, with recurrence of infections after treatment interruption. In this study, the high susceptibility (25.71%) of immunodepressed renal transplant patients to Legionella pneumophila serogroup 1 nosocomial infections is documented. The importance of the implementation and maintenance of water decontamination measures for prophylaxis of the infection is also clearly evident.

AbstractIn the field study period from 2006 to 2010, the incidence and severity of sharp eyespot caused byRhizoctoniawere recorded on 36 cultivars of triticale at the milk ripe growth stage. Four localities in north-central Poland were included: Chrząstowo, Dębina, Kończewice and Minikowo. The susceptibility of the seedlings of 30 cultivars of triticale toR. cerealis(AG-D subgroup I) andR. solani(AG-5) was studied in the laboratory. There was much variation in incidence and severity of sharp eyespot between years and locations. The disease was most intense at Chrząstowo. At this location, the mean percentage of diseased stems on 28 cultivars was 2.6-35.7 (-55.0), and the mean disease index was 0.7-15.6 (-24.5), with the lowest and highest values in 2008 and 2009, respectively. At Minikowo, the disease was least intense. At this location, the mean percentage of diseased stems on 23 cultivars was 1.0-4.6 (-18.0), and the mean disease index was 0.3-1.4 (-6.3), with the lowest and highest values in 2006 and 2007, respectively. The cultivars with least intense disease were Tulus and Atletico (Chrząstowo), Grenado and Zorro (Dębina), Krakowiak and Tornado (Kończewice), and Woltario and Constans (Minikowo). The cultivars with most intense disease were Alekto (Chrząstowo), Baltiko (Dębina), Pawo (Kończewice) and Borwo (Minikowo). MostlyR. cerealiswas isolated from the diseased stems;R. solaniwas isolated only sporadically. There was a wide variation in the susceptibility of triticale cultivars toRhizoctonia. Most triticale seedlings inoculated withR. cerealisproduced symptoms typical of sharp eyespot. Seedlings inoculated withR. solaniformed extended lesions with no defined borders. Most symptoms developed on coleoptiles, with less symptoms on the leaves and the least on the roots. There was much variation in susceptibility of triticale cultivars to bothRhizoctoniaspecies. Cultivars were grouped into six categories according to the intensity of seedling infection. Categories 1, 2 and 3, representing low, moderate and high susceptibility toR. cerealis, included 17, 10 and 3 cultivars, respectively.Categories 4, 5 and 6, representing low, moderate and high susceptibility toR. solani, included 3, 12 and 15 cultivars, respectively.Cultivars Baltiko and Zorro had low, and cv. Cultivo had high susceptibility to bothRhizoctoniaspecies. No cultivar was resistant toRhizoctonia. There was a positive correlation between infection byR. cerealisandR. solani.Infection of coleoptiles byR. cerealisorR. solaniwas significantly correlated with infection of leaves. No correlation between intensity of sharp eyespot on triticale plants in the field and on seedlings in controlled conditions was found.
