    The present study was designed to investigate the effects of prophylactic antibiotic therapy and the cost-effectiveness of Cefazolin (CEZ) and Sulbactam/Ampicillin (SBT/ABPC) in gastric cancer surgery employing clinical pathway. 157 patients (62 in the CEZ group and 95 in the SBT/ABPC group), who underwent surgery for gastric cancer at the First Department of Surgery of our hospital, were investigated. There was no significant difference between the groups with regard to sex, age, incidence of complication, stage of cancer, surgical method, operative time and blood loss, length of hospitalization, the appearance of systemic inflammatory response syndrome (SIRS), changes body temperature, white blood cell count (WBC), C-reactive protein (CRP), or clinical outcome of postoperative care by a nurse during post-operation for 7 days. The prophylactic effect of infection was also no different between the CEZ (69.4%) and SBT/ABPC (69.5%) groups. In contrast, decision analysis strongly indicated that the anticipate cost of antibiotics was higher in the latter group (yen 20402) than in the CEZ group (yen 15556), suggesting that the prophylactic effect of CEZ may be more cost-effective. Thus, evaluations of pharmacotherapy from the aspect of cost may be one of the important responsibility of hospital pharmacists in the future.

    Vogl, Raimund; Gildhorn, Antje; Labitzke, Jörg; Wibberg, Michael

    An der Westfälischen Wilhelms-Universität Münster (WWU) wurde bereits 1996 ein tragfähiges, kooperativ ausgerichtetes System der IT-Governance im Zusammenspiel zentraler und dezentraler IT-Leistungserbringer etabliert. Um den Anforderungen an ein integriertes Informationsmanagement im Überlappungsfeld von Information, Kommunikation und Medien (IKM) durch das Zusammenspiel der zentralen Einrichtungen Universitätsverwaltung (UniV), Universitäts- und Landesbibliothek (ULB) und Zentrum für Informationsverarbeitung (ZIV) gerecht zu werden, wurde 2003 der IKM-Service institutionalisiert. In diesem Rahmen wurde das Projekt Münster Information System for Research and Organization (MIRO) entwickelt, das als Leistungszentrum für Forschungsinformation von der DFG gefördert wird. Die bisherigen Projekterfahrungen, erreichten Ziele und verbleibenden Aufgaben werden dargestellt. Im Projektverlauf haben sich insbesondere die etablierten IT-Governance und Versorgungs-Strukturen sowie die Unterstützung der Hochschulleitung als essentielle Erfolgskriterien erwiesen.

    All highly developed nations round the world have gradually assumed the responsibility for the quality of the environment at their respective territories by creating the preconditions (by setting forth concepts, and the legislative, economic and institutional framework as well as the educational information and resources systems) stimulating both individuals and corporate bodies to take care of the environment. Damaging the environment is punished. The approach has been successful in most of the countries. Companies and individuals have begun to recognize the correlations existing between their production and consumption activities and the environment and their direct responsibility for the environmental conditions, realizing that to remove a source of environmental damage or to minimis the damage caused by it in both necessary and more beneficial than being penalized (up to ban of operation) both economically and in broader social terms for failing to comply with the relevant laws. Since 1990 a number of the so-called {open_quotes}ecological{close_quotes} laws, formerly sorely lacking, have been enacted, such as the Environment Act, the Environmental Effects Assessment Act, and the Wastes Act, and the Clean Air Act has been fundamentally amended so that to meet again the requirements of effective protection of the atmosphere from pollutants. In the area of economic tools, the duty of the waste producer to pay for the waste produced was introduced, the fines for air pollution were raised significantly and the polluted waste water discharge fines were amended to keep pace with the devaluation of the local currency.

    To validate the policy of administering cefazolin (CEZ) as a first-line antibiotic to children who are hospitalized with their first febrile urinary tract infection (UTI), we evaluated microbial susceptibility to CEZ and the efficacy of CEZ. The 75 enrolled children with febrile UTI were initially treated with CEZ. Switching CEZ was not required in 84% of the patients. The median fever duration, prevalence of bacteremia, prevalence of UTI caused by extended-spectrum β-lactamase (ESBL)-producing Escherichia coli, and median duration of hospitalization were significantly higher in the CEZ-ineffective group. The risks of vesicoureteral reflux, indication of operation, and renal scarring are not increased, even when CEZ is ineffective as a first-line antibiotic. CEZ is effective in more than 80% of pediatric patients with their first febrile UTI, but it should be switched to appropriate antibiotics considering sepsis or the ESBL-producing Enterobacteriaceae pathogen, when fever does not improve within 72 hours.

    First-generation cephalosporins such as cefazolin (CEZ) have been widely used for mastitis treatment in dairy cattle. However, the use of antibiotics results in the presence of antibiotic residues in milk, which is used for human consumption. Nisin A, a bacteriocin produced by Lactococcus lactis, has been used as a broad-spectrum food preservative for over 50 years. Therefore, a combination of CEZ and nisin A might provide an extended activity spectrum against mastitis pathogens and reduce the antibiotic dose for mastitis treatment. This study aimed to evaluate the combined effect of CEZ and nisin A against mastitis pathogens using the checkerboard and time-kill assays. In the checkerboard assay, the CEZ-nisin A combination exhibited a synergistic effect against Staphylococcus aureus (n=20/20) and Enterococcus faecalis (n=13/18), and meanwhile exhibited a mostly additive effect against Staphylococcus intermedius (n=12/20), Streptococcus agalactiae (n=10/10), Streptococcus dysgalactiae (n=18/18), and Escherichia coli (n=14/18). There were no indifferent or antagonistic effects between CEZ and nisin A. In the time-kill assay, the CEZ-nisin A combination at 0.5 × or 1 × minimum inhibitory concentration exhibited synergistic reduction of bacterial growth by over 3 log10 colony forming units per ml relative to that observed with either antimicrobial substance alone. These results suggest that the CEZ-nisin A combination can be used for developing an intramammary infusion for mastitis treatment, with lower antibiotic concentrations than normal.

    In April and August 2015, two major fires in the Chernobyl Exclusion Zone (CEZ) caused concerns about the secondary radioactive contamination that might have spread over Europe. The present paper assessed, for the first time, the impact of these fires over Europe. About 10.9 TBq of 137Cs, 1.5 TBq of 90Sr, 7.8 GBq of 238Pu, 6.3 GBq of 239Pu, 9.4 GBq of 240Pu and 29.7 GBq of 241Am were released from both fire events corresponding to a serious event. The more labile elements escaped easier from the CEZ, whereas the larger refractory particles were removed more efficiently from the atmosphere mainly affecting the CEZ and its vicinity. During the spring 2015 fires, about 93% of the labile and 97% of the refractory particles ended in Eastern European countries. Similarly, during the summer 2015 fires, about 75% of the labile and 59% of the refractory radionuclides were exported from the CEZ with the majority depositing in Belarus and Russia. Effective doses were above 1 mSv y−1 in the CEZ, but much lower in the rest of Europe contributing an additional dose to the Eastern European population, which is far below a dose from a medical X-ray.

    The anti-neoplastic prodrug, cyclophosphamide, requires biotransformation to phosphoramide mustard (PM), which partitions to volatile chloroethylaziridine (CEZ). PM and CEZ are ovotoxicants, however their ovarian biotransformation remains ill-defined. This study investigated PM and CEZ metabolism mechanisms through the utilization of cultured postnatal day 4 (PND4) Fisher 344 (F344) rat ovaries exposed to vehicle control (1% dimethyl sulfoxide (DMSO)) or PM (60μM) for 2 or 4 days. Quantification of mRNA levels via an RT2 profiler PCR array and target-specific RT-PCR along with Western blotting found increased mRNA and protein levels of xenobiotic metabolism genes including microsomal epoxide hydrolase (Ephx1) and glutathione S-transferase isoform pi (Gstp). PND4 ovaries were treated with 1% DMSO, PM (60μM), cyclohexene oxide to inhibit EPHX1 (CHO; 2mM), or PM + CHO for 4 days. Lack of functional EPHX1 increased PM-induced ovotoxicity, suggesting a detoxification role for EPHX1. PND4 ovaries were also treated with 1% DMSO, PM (60μM), BSO (Glutathione (GSH) depletion; 100μM), GEE (GSH supplementation; 2.5mM), PM ± BSO, or PM ± GEE for 4 days. GSH supplementation prevented PM-induced follicle loss, whereas no impact of GSH depletion was observed. Lastly, the effect of ovarian GSH on CEZ liberation and ovotoxicity was evaluated. Both untreated and GEE-treated PND4 ovaries were plated adjacent to ovaries receiving PM + GEE or PM + BSO treatments. Less CEZ-induced ovotoxicity was observed with both GEE and BSO treatments indicating reduced CEZ liberation from PM. Collectively, this study supports ovarian biotransformation of PM, thereby influencing the ovotoxicity that ensues. PMID:25070981

    Temporal and spatial variations of leaf traits caused conflicting conclusions and great estimating errors of total carbon budget on crown scales. However, there is no effective method to quantitatively describe and study heterogeneous patterns of crowns yet. In this study, dynamic spatial patterns of typical ecological factors on crown scales were investigated during two sky conditions, and CEZs (crown ecological zones) method was developed for spatial crown zoning, within which leaf traits were statistically unchanged. The influencing factors on hourly and spatial variations of leaf dark respiration (Rd) were analysed, and total crown respiration (Rt) was estimated based on patterns of CEZs. The results showed that dynamic spatial patterns of air temperature and light intensity changed significantly by CEZs in special periods and positions, but not continuously. The contributions of influencing factors on variations of Rd changed with crown depth and sky conditions, and total contributions of leaf structural and chemical traits were higher during sunny days than ecological factors, but lower during cloudy days. The estimated errors of Rt may be obviously reduced with CEZs. These results provided some references for scaling from leaves to crown, and technical foundations for expanding lab-control experiments to open field ones.

  3. An Estimation of Profitability of Investment Projects in The Oil and Gas Industry Using Real Options Theory / Ocena Opłacalności Projektów Inwestycyjnych W Przemyśle Naftowym Z Wykorzystaniem Teorii Opcji Realnych

    Paper discusses issues relating to the valuation of investment efficiency in the oil and gas industry using a real options theory. The example of investment pricing using real options was depicted and it was confronted with the analysis executed with the use of traditional methods. Indicators commonly used to evaluate profitability of investment projects, based on a discounted cash flow method, have a few significant drawbacks, the most meaningful of which is staticity which means that any changes resulting from a decision process during the time of investment cannot be taken into consideration. In accordance with a methodology that is currently used, investment projects are analysed in a way that all the key decisions are made at the beginning and are irreversible. This approach assumes, that all the cash flows are specified and does not let the fact that during the time of investment there may appear new information, which could change its original form. What is also not analysed is the possibility of readjustment, due to staff managment's decisions, to the current market conditions, by expanding, speeding up/slowing down, abandoning or changing an outline of the undertaking. In result, traditional methods of investment projects valuation may lead to taking wrong decisions, e.g. giving up an owned exploitation licence or untimely liquidation of boreholes, which seem to be unprofitable. Due to all the above-mentioned there appears the necessity of finding some other methods which would let one make real and adequate estimations about investments in a petroleum industry especially when it comes to unconventional resources extraction. One of the methods which has been recently getting more and more approval in a world petroleum economics, is a real options pricing method. A real option is a right (but not an obligation) to make a decision connected with an investment in a specified time or time interval. According to the method a static model of pricing using DCF is no longer used; an investment project is divided into a series of steps and after each one there is a range of possible investment decisions, technical and organizational issues and all the others called `real options'. This lets one take many different varieties of modyfiying a strategy while pricing the project. This also makes it possible to react to the changing inner and outer situation and introducing new information while accomplishing the investment project. Owing to those, the decision process is a continuous operation, what is an actual vision of a real investment project management in the petroleum industry.

  4. Unique Project of Single-Cutting Head Longwall Shearer Used for Thin Coal Seams Exploitation / Projekt Jednoorganowego Kombajnu ŚCIANOWEGO O Specjalnej Konstrukcji Przeznaczonego do Eksploatacji POKŁADÓW Cienkich

    Problem of thin hard coal seams exploitation, including chosen data related with their resources in Poland, has been discussed in the introduction of the present study. On the basis of actually operated machines the assumptions, which should be satisfied by the longwall shearer used for exploitation of thin hard coal seams, have been made. A project of such longwall shearer combined with band conveyor and mechanized longwall support, including description of the machine operation technology and analysis of possible day output achievement, have been presented. Polska dysponuje stosunkowo dużymi zasobami surowców energetycznych, a ciągle rosnące zapotrzebowanie na energię skłania do ich racjonalnego wykorzystywania. Jedną z możliwości takiego racjonalnego gospodarowania zasobami naturalnymi jest eksploatacja węgla kamiennego z pokładów cienkich. W związku z wybieraniem coraz cieńszych pokładów węgla, zalegających bardzo głęboko, w trudnych warunkach górniczo-geologicznych napotyka się na duże problemy związane z uzyskaniem wymaganej wydajności wydobycia przy użyciu stosowanych aktualnie metod. Przyjmuje się, ze pokłady cienkie to takie o miąższości od 1.0 m do 1.5 m i właśnie ta niewielka wysokość wyrobiska ścianowego powoduje szereg ograniczeń związanych z efektywną eksploatacją węgla. Na podstawie dostępnych danych określono, że ilości węgla kamiennego w cienkich pokładach wynosi około 600 mln Mg. Znaczna część pokładów cienkich w ostatnich latach została przeklasyfikowana na nieprzemysłowe, co pozwala stwierdzić, że rzeczywista ilość węgla w pokładach cienkich jest znacznie większa. Na podstawie analizy wad i zalet jak i danych technicznych produkowanych obecnie maszyn, określono wytyczne i założenia do nowego rozwiązania maszyny urabiającej przeznaczonej do wydobywania węgla w ścianach niskich. Kombajn do eksploatacji cienkich pokładów powinien spełniać następujące wymagania (Bołoz, 2012): • praca w systemie ścianowym, • zastosowanie frezowania jako metody skrawania, • rozdzielenie procesu frezowania od procesu ładowania, • zastosowanie pełnej automatyzacja pracy, • zastosowanie cięgnowego systemu posuwu, • możliwość rozpoczynania nowego skrawu bez konieczności zawrębiania, • gabaryty dostosowane do pracy w ścianach o wysokości od 1.0 m do 1.6 m, praca systemem dwukierunkowym. Fig. 2 przedstawia koncepcję kombajnu jednoorganowego. Kombajn ten składa się z kadłuba 2, jednego zamocowanego centralnie organu urabiającego 1 oraz dwóch rozkładanych ładowarek odkładniowych 3 i 4. Ładowarka 3 znajduje się w pozycji czynnej, natomiast ładowarka 4 w biernej. Kombajn jest ciągnięty po rynnach przenośnika 5 za pomocą łańcucha 6. Łańcuch 7 jest gałęzią bierną dla przedstawionego zwrotu prędkości. Podane, orientacyjne wymiary wynikają z analizy dotychczasowych rozwiązań kombajnów, głowic strugowych oraz założonego zakresu wysokości wyrobiska ścianowego (Krauze, 2006; Bołoz, 2012). Dla zaproponowanego rozwiązania przyjęto szereg koniecznych wielkości i przeprowadzono analizę możliwego do uzyskania wydobycia dobowego. Zestawione tabelarycznie wyniki umożliwiają określenie wydobycia dobowego możliwego do uzyskania przy określonych wartościach parametrów geometrycznych ściany, kinematycznych kombajnu oraz organizacyjnych pracy ściany. Dla założonych parametrów można stwierdzić, że minimalne wydobycie dobowe na poziomie Vd = 4032 Mg/d uzyskano dla L = 180 m, tp = 11 min, H = 1.0 m oraz T = 12 h/d. Maksymalne wydobycie dobowe na poziomie Vd = 11 612 Mg/d uzyskać można dla L = 300 m, tp = 0 min, H = 1.6 m oraz T = 18 h/d. Na wydobycie dobowe największy wpływ ma dobowy czas pracy ściany a następnie czas przekładki (Bołoz, 2012). Średnica organu dla takiego kombajnu dobierana jest do grubości pokładu. W przedmiotowym rozwiązaniu przyjęto organ o konstrukcji przestrzennej (belki nożowe zamiast płatów), aby powstający podczas frezowania urobek mógł spadać na spąg (Krauze, 2012b). Przykładowe rozwiązanie organu przestrzennego przedstawia fig. 3. Funkcję ładowania, realizowaną normalnie przez płaty, przejmują ładowarki. Rozdzielenie procesu ładowania od procesu frezowania jest jedną z najważniejszych zalet prezentowanego rozwiązania. Podczas pracy w ścianie parametry kinematyczne kombajnu mogą być zwiększane bez ryzyka wystąpienia problemów z ładowaniem na przenośnik, co obok możliwości ruchowych kombajnisty było głównym czynnikiem hamującym wzrost wydobycia. Załadunek urobku na przenośnik odbywa się za pomocą ładowarki, która po zmianie kierunku urabiania składa się, natomiast druga ustawiana jest w pozycji roboczej (Krauze, 2010). Kombajn porusza się tradycyjnie po rynnie przenośnika, jednak przy zastosowaniu cięgnowego systemu posuwu, który zrealizowany jest za pomocą napędów znajdujących się w chodnikach. Rozwiązanie takie umożliwia znaczne zmniejszenie gabarytów kombajnu dzięki usunięciu ciągników z kadłuba. Należy zaznaczyć, że w prezentowanym rozwiązaniu zakłada się zastosowanie pełnej automatyzacja pracy kombajnu i pozostałych maszyn ścianowych, co pozwala na urabianie calizny bez obecności załogi bezpośrednio w wyrobisku. Ma to duże znaczenie dla możliwości zwiększenia prędkości posuwu, szczególnie przy zakresie wysokości 1.0 m÷1.6 m. Przy wykorzystaniu znanych, z rozwiązań strugowych, systemów automatyki, sterowania i diagnostyki wprowadzenie automatyzacji procesu nie będzie stanowiło znaczącego problemu. W proponowanym rozwiązaniu kombajn ma możliwość wyjechania do chodnika na tyle, aby możliwe było zrealizowanie przekładki jak w przypadku strugów. Uzyskuje się wtedy krótki czas przekładki, który w skrajnym przypadku może zmieścić się w tzw. czasie organizacyjnym ściany. Ponadto urabianie odbywa się pełnym zabiorem na całej długości ściany co również korzystnie wpływa na wydobycie. Przekładkę realizować będą, oprócz układów przesuwnych sekcji, układy przesuwne napędów zlokalizowane w chodnikach lub ewentualnie obudowa skrzyżowań. Do sterowania położeniem kombajnu jednoorganowego, a w szczególności kierunkiem eksploatacji na wybiegu ściany (wznios, upad), zastosowane będą siłowniki korekcyjne łączące belkę układu przesuwnego sekcji z rynną przenośnika. Kopalnie jak i producenci sprzętu górniczego wykazują coraz większe zainteresowanie możliwością skutecznej eksploatacji pokładów cienki. Zaproponowany kompleks do eksploatacji cienkich pokładów wyposażony w kombajn jednoorganowy przeznaczony jest do pracy w technologii urabiania dwukierunkowego. Charakterystyczną cechą tej technologii jest brak fazy zawrębiania oraz praca na pełny zabiór na całej długości ściany. W przypadku zmiany grubości pokładu możliwa jest zmiana organu, natomiast sterowanie w kierunku wybiegu odbywać się będzie za pomocą siłowników korekcyjnych. Opracowanie technologii pracy kompleksu wyposażonego w kombajn jednoorganowy, analiza możliwego do osiągnięcia wydobycia dobowego, przy jego zastosowaniu oraz określenie wymaganych parametrów maszyn kompleksu ścianowego, a w szczególności kombajnu, potwierdza poprawność przyjętych założeń.

    In 2015, two major fires in the Chernobyl Exclusion Zone (CEZ) have caused concerns about the secondary radioactive contamination that might have spread over Europe. The total active burned area was estimated to be about 15,000 hectares, of which 9000 hectares burned in April and 6000 hectares in August. The present paper aims to assess, for the first time, the transport and impact of these fires over Europe. For this reason, direct observations of the prevailing deposition levels of 137Cs and 90Sr, 238Pu, 239Pu, 240Pu and 241Am in the CEZ were processed together with burned area estimates. Based on literature reports, we made the conservative assumption that 20% of the deposited labile radionuclides 137Cs and 90Sr, and 10% of the more refractory 238Pu, 239Pu, 240Pu and 241Am, were resuspended by the fires. We estimate that about 10.9 TBq of 137Cs, 1.5 TBq of 90Sr, 7.8 GBq of 238Pu, 6.3 GBq of 239Pu, 9.4 GBq of 240Pu and 29.7 GBq of 241Am were released from both fire events. These releases could be classified as of "Level 3" on the relative INES (International Nuclear Events Scale) scale, which corresponds to a serious incident, in which non-lethal deterministic effects are expected from radiation. To simulate the dispersion of the resuspended radionuclides in the atmosphere and their deposition onto the terrestrial environment, we used a Lagrangian dispersion model. Spring fires redistributed radionuclides over the northern and eastern parts of Europe, while the summer fires also affected Central and Southern Europe. The more labile elements escaped more easily from the CEZ and then reached and deposited in areas far from the source, whereas the larger refractory particles were removed more efficiently from the atmosphere and thus did mainly affect the CEZ and its vicinity. For the spring 2015 fires, we estimate that about 80% of 137Cs and 90Sr and about 69% of 238Pu, 239Pu, 240Pu and 241Am were deposited over areas outside the CEZ. 93% of the labile and 97% of

    Prevalence of drug-resistant bacteria in wildlife can reveal the actual level of anthropological burden on the wildlife. In this study, we isolated two multiple drug-resistant strains, GG6-2 and GG6-1-1, from 27 fresh feces of wild western lowland gorillas in Moukalaba-Doudou National Park, Gabon. Isolates were identified as Achromobacter xylosoxidans and Providencia sp., respectively. Minimum inhibitory concentrations of the following 12 drugs-ampicillin (ABPC), cefazolin (CEZ), cefotaxime (CTX), streptomycin (SM), gentamicin (GM), kanamycin (KM), tetracycline (TC), nalidixic acid (NA), ciprofloxacin (CPFX), colistin (CL), chloramphenicol (CP) and trimethoprim (TMP)-were determined. Isolate GG6-2 was resistant to all antimicrobials tested and highly resistant to CTX, SM, TC, NA and TMP. Isolate GG6-1-1 was resistant to ABPC, CEZ, TC, CL, CP and TMP.

    1998-06-01

    Many concepts, systems, technical approaches, technologies, ideas, agreements, and disagreements were vigorously discussed during the course of the 2-day workshop. The workshop was successful in generating intensive discussions on the merits of the proposed concept that includes removal of radionuclides by plants and trees (phytoremediation) to clean up soil in the Chornobyl Exclusion Zone (CEZ), use of the resultant biomass (plants and trees) to generate electrical power, and incorporation of ash in concrete casks to be used as storage containers in a licensed repository for low-level waste. Twelve years after the Chornobyl Nuclear Power Plant (ChNPP) Unit 4 accident, which occurred on April 26, 1986, the primary 4radioactive contamination of concern is from radioactive cesium ({sup 137}Cs) and strontium ({sup 90}Sr). The {sup 137}Cs and {sup 90}Sr were widely distributed throughout the CEZ. The attendees from Ukraine, Russia, Belarus, Denmark and the US provided information, discussed and debated the following issues considerably: distribution and characteristics of radionuclides in CEZ; efficacy of using trees and plants to extract radioactive cesium (Cs) and strontium (Sr) from contaminated soil; selection of energy conversion systems and technologies; necessary infrastructure for biomass harvesting, handling, transportation, and energy conversion; radioactive ash and emission management; occupational health and safety concerns for the personnel involved in this work; and economics. The attendees concluded that the overall concept has technical and possibly economic merits. However, many issues (technical, economic, risk) remain to be resolved before a viable commercial-scale implementation could take place.

    The influence of microstructure on nucleation and propagation of fatigue cracks in two {beta} titanium alloys, {beta}-CEZ (developed by CEZUS, France) and VT 22 (Russia), was investigated. For the {beta}-CEZ alloy a comparison between lamellar ({beta} processed) and bi-modal microstructures ({alpha}+{beta} processed) at a yield stress level of 1200 MPa was performed. Bi-modal microstructures showed higher ductility, higher LCF and HCF strength level and a higher resistance against microcrack propagation whereas lamellar microstructures showed a higher resistance against macrocrack propagation and fracture toughness. These findings could be explained on the basis of the {beta} grain size and of the {alpha} plate dimensions. In the second part of this work a comparison between the bi-modal condition of the {beta}-CEZ alloy and the VT 22 alloy (at the same yield stress level of 1,200 MPa) was made. The differences in the mechanical properties will be discussed in terms of differences in {alpha} plate dimensions and uniformity of the {beta} grain structure.

    Mass drug administration (MDA) with ivermectin for onchocerciasis was provided in Guatemala's Central Endemic Zone (CEZ) over a 24 year period (1988-2011). Elimination of Onchocerca volvulus transmission was declared in 2015 after a three year post MDA surveillance period (2012-2014) showed no evidence of recrudescence. The purpose of the present study was to evaluate the knowledge, attitudes and practices (KAP) towards onchocerciasis and ivermectin among residents in the post endemic CEZ. A major interest in this study was to determine what community residents thought about the end of the ivermectin MDA program. A total of 148 interviews were conducted in November 2014 in four formerly hyperendemic communities using a standard questionnaire on smart phones. The majority (69%) of respondents knew that the MDA program had ended because the disease was no longer present in their communities, but a slight majority (53%) was personally unsure that onchocerciasis had really been eliminated. Sixty-three percent wanted to continue to receive ivermectin because of this uncertainty, or because ivermectin is effective against intestinal worms. Eighty-nine percent of respondents said that they would seek medical attention immediately if a family member had symptoms of onchocerciasis (especially the presence of a nodule), which is a finding very important for ongoing surveillance. Many respondents wanted to continue receive ivermectin and more than half did not believe onchocerciasis had been eliminated. The ministry of health outreach services should be prepared to address ongoing concerns about onchocerciasis in the post endemic CEZ.

  12. The model of root graviresponse with retarded arguments

    NASA Astrophysics Data System (ADS)

    Kondrachuk, Alexander

    The graviperception mechanism (GPM) of the roots of higher plants localized in the cap region of a root and supposedly related to statoliths sedimentation produces the signals in response to the change of the root axis orientation relative to the gravity vector G. Meanwhile, the regions (Distal Elongation Zone -DEZ and Central Elongation Zone-CEZ), where the signals initiate the changes of the growth rates of the upper and lower flanks of the root, are located at the significant distances from the cap (thousands microns for some plants). It causes the time delays between the relocation of statoliths in statocytes and the change of the growth rates in elongation zones. It is suggested that the signal targeting the CEZ modulates the initially uniform lateral distribution of some specific substances (S) in the cap region. Then already nonhomogeneous lateral distribution of S is transferred to the CEZ to initiate the change of the growth rates of the opposite flanks. It results in the bending of the root in the line of G and thus in the change of the GPM signal in the cap region. In the present model the kinetics of a root apex bending (angle A) in response to the time (t)-dependent change of the G orientation is described by the integro-differential equation in A(t). The main peculiarity of this model is the presence of retarded (time-delayed) arguments t-TCEZ and t-TDEZ . In this case the solutions of this equation depend on the preceding kinetics of A(t) during the time delays TCEZ and TDEZ . It is suggested that the signals activating the CEZ and DEZ are of different nature. The work is focused on two problems concerning the modeling of the effects of time-delay(s) on the root bending. The first problem supposes the existence of one zone (CEZ) and one time-delay TCEZ . This equation was studied and solved using analytical and numerical methods. We analyzed the model as to whether it can be used to describe the kinetics of root graviresponse in the case of different

    2003-12-01

    The antibacterial activity of cefmetazole (CMZ) against clinical isolates from 15 medical institutions all over Japan was evaluated yearly for two years from June 2000 to March 2002 and compared with that of other parenteral beta-lactams, cefazolin (CEZ), cefotiam (CTM), sulbactam/cefoperazone (SBT/CPZ), and flomoxef (FMOX). In the first surveillance from June 2000 to March 2001, 575 isolates of 13 species were tested, and 548 isolates of the same 13 species were tested in the second surveillance from April 2001 to March 2002. In these surveillances spanning two years, the MIC90s of CMZ against the bacterial species tested hardly differed. Changes in percent resistance of each species to CMZ (MIC of CMZ > or = 32 micrograms/mL) were as follows: methicillin-susceptible Staphylococcus aureus (MSSA, 0%-->0%), methicillin-resistant Staphylococcus aureus (MRSA, 73%-->87%), Staphylococcus epidermidis (19%-->32%), other coagulase-negative Staphylococcus spp. (other CNS, 13%-->18%), Escherichia coli (4%-->1%), Klebsiella pneumoniae (3%-->4%), Klebsiella oxytoca (0%-->0%), Proteus mirabilis (2%-->2%), Proteus vulgaris (14%-->7%), Morganella morganii (7%-->0%), Providencia spp. (17%-->0%), Peptostreptococcus spp. (0%-->0%), Bacteroides fragilis (10%-->11%), and other Bacteroides spp. (79%-->88%). The change in percent resistance of MRSA, S. epidermidis, other CNS, and other Bacteroides spp. tended to increase. In addition, the percent resistance of B. fragilis was 10%. It is necessary to pay much attention to the trends observed in these species. Compared to other drugs tested, against MSSA, the activity of CMZ was inferior to that of CEZ, CTM, and FMOX and superior to that of SBT/CPZ. Against MRSA, S. epidermidis, and CNS, the tested drugs exhibited little activity. Against Gram-negative bacteria, the activity of CMZ was almost superior to that of CEZ and CTM, and inferior to that of FMOX. Against B. fragilis and other Bacteroides spp., the activity of CMZ was almost

  18. Two distinct regions of response drive differential growth in Vigna root electrotropism

    2000-01-01

    Although exogenous electric fields have been reported to influence the orientation of plant root growth, reports of the ultimate direction of differential growth have been contradictory. Using a high-resolution image analysis approach, the kinetics of electrotropic curvature in Vigna mungo L. roots were investigated. It was found that curvature occurred in the same root toward both the anode and cathode. However, these two responses occurred in two different regions of the root, the central elongation zone (CEZ) and distal elongation zone (DEZ), respectively. These oppositely directed responses could be reproduced individually by a localized electric field application to the region of response. This indicates that both are true responses to the electric field, rather than one being a secondary response to an induced gravitropic stimulation. The individual responses differed in the type of differential growth giving rise to curvature. In the CEZ, curvature was driven by inhibition of elongation, whereas curvature in the DEZ was primarily due to stimulation of elongation. This stimulation of elongation is consistent with the growth response of the DEZ to other environmental stimuli.

    This paper discusses the engineering considerations related to the design of a new 110 MWe atmospheric fluidized bed boiler (CFB) and boiler island auxiliaries for installation at the CEZ, a.s. (Czech Republic Utility) Ledvice Power Station. The plant is located in the northwest Bohemia area of the Czech Republic in the foothills of the Krusne Hory Mountains, between the towns of Bilina and Teplice. The type of fuel to be burned in the CFB is brown coal which requires unique design considerations in as well as the particular boiler operational parameters. The impetus behind the addition of this new CFB at the plant is that the existing pulverized coal fired steam generator which was put in service in 1969 is unable to meet new regulations and laws regarding compliance with the protection of the environment and will be replaced once the new CFB unit is brought into service. A technical-economic study conducted by CEZ, a.s. evaluated CFB technology as the most advantageous from a long-term standpoint. The following variations were considered in the study: boiler retrofit and construction of new ash handling equipment; implementation of the combined cycle based upon natural gas; and reconstruction of the boiler equipment with transition to atmospheric fluid-bed combustion. The selection of the supplier of fluid-bed boiler was performed with an emphasis of the bidders` references as for the construction and operation of fluid-bed boilers with the outputs of min. 300 t/hr.

    Polar auxin transport, mediated by two distinct plasma membrane-localized auxin influx and efflux carrier proteins/complexes, plays an important role in many plant growth and developmental processes including tropic responses to gravity and light, development of lateral roots and patterning in embryogenesis. We have previously shown that the Arabidopsis AGRAVITROPIC 1/PIN2 gene encodes an auxin efflux component regulating root gravitropism and basipetal auxin transport. However, the regulatory mechanism underlying the function of AGR1/PIN2 is largely unknown. Recently, protein phosphorylation and dephosphorylation mediated by protein kinases and phosphatases, respectively, have been implicated in regulating polar auxin transport and root gravitropism. Here, we examined the effects of chemical inhibitors of protein phosphatases on root gravitropism and basipetal auxin transport, as well as the expression pattern of AGR1/PIN2 gene and the localization of AGR1/PIN2 protein. We also examined the effects of inhibitors of vesicle trafficking and protein kinases. Our data suggest that protein phosphatases, sensitive to cantharidin and okadaic acid, are likely involved in regulating AGR1/PIN2-mediated root basipetal auxin transport and gravitropism, as well as auxin response in the root central elongation zone (CEZ). BFA-sensitive vesicle trafficking may be required for the cycling of AGR1/PIN2 between plasma membrane and the BFA compartment, but not for the AGR1/PIN2-mediated root basipetal auxin transport and auxin response in CEZ cells.

    We report the elimination of Onchocerca volvulus transmission from the Central Endemic Zone (CEZ) of onchocerciasis in Guatemala, the largest focus of this disease in the Americas and the first to be discovered in this hemisphere by Rodolfo Robles Valverde in 1915. Mass drug administration (MDA) with ivermectin was launched in 1988, with semiannual MDA coverage reaching at least 85% of the eligible population in > 95% of treatment rounds during the 12-year period, 2000-2011. Serial parasitological testing to monitor MDA impact in sentinel villages showed a decrease in microfilaria skin prevalence from 70% to 0%, and polymerase chain reaction (PCR)-based entomological assessments of the principal vector Simulium ochraceum s.l. showed transmission interruption by 2007. These assessments, together with a 2010 serological survey in children 9-69 months of age that showed Ov16 IgG4 antibody prevalence to be < 0.1%, meeting World Health Organization (WHO) guidelines for stopping MDA, and treatment was halted after 2011. After 3 years an entomological assessment showed no evidence of vector infection or recrudescence of transmission. In 2015, 100 years after the discovery of its presence, the Ministry of Health of Guatemala declared onchocerciasis transmission as having been eliminated from the CEZ. © The American Society of Tropical Medicine and Hygiene.

We have previously shown that the Arabidopsis AGRAVITROPIC 1/PIN2 gene encodes an auxin efflux component regulating root gravitropism and basipetal auxin transport. However, the regulatory mechanism underlying the function of AGR1/PIN2 is largely unknown. Recently, protein phosphorylation and dephosphorylation mediated by protein kinases and phosphatases, respectively, have been implicated in regulating polar auxin transport and root gravitropism. Here, we examined the effects of chemical inhibitors of protein phosphatases on root gravitropism and basipetal auxin transport, as well as the expression pattern of AGR1/PIN2 gene and the localization of AGR1/PIN2 protein. We also examined the effects of inhibitors of vesicle trafficking and protein kinases. Our data suggest that protein phosphatases, sensitive to cantharidin and okadaic acid, are likely involved in regulating AGR1/PIN2-mediated root basipetal auxin transport and gravitropism, as well as auxin response in the root central elongation zone (CEZ). BFA-sensitive vesicle trafficking may be required for the cycling of AGR1/PIN2 between plasma membrane and the BFA compartment, but not for the AGR1/PIN2-mediated root basipetal auxin transport and auxin response in CEZ cells.

    We report the elimination of Onchocerca volvulus transmission from the Central Endemic Zone (CEZ) of onchocerciasis in Guatemala, the largest focus of this disease in the Americas and the first to be discovered in this hemisphere by Rodolfo Robles Valverde in 1915. Mass drug administration (MDA) with ivermectin was launched in 1988, with semiannual MDA coverage reaching at least 85% of the eligible population in > 95% of treatment rounds during the 12-year period, 2000–2011. Serial parasitological testing to monitor MDA impact in sentinel villages showed a decrease in microfilaria skin prevalence from 70% to 0%, and polymerase chain reaction (PCR)-based entomological assessments of the principal vector Simulium ochraceum s.l. showed transmission interruption by 2007. These assessments, together with a 2010 serological survey in children 9–69 months of age that showed Ov16 IgG4 antibody prevalence to be < 0.1%, meeting World Health Organization (WHO) guidelines for stopping MDA, and treatment was halted after 2011. After 3 years an entomological assessment showed no evidence of vector infection or recrudescence of transmission. In 2015, 100 years after the discovery of its presence, the Ministry of Health of Guatemala declared onchocerciasis transmission as having been eliminated from the CEZ. PMID:26503275

    For the post-marketing surveillance of cefmetazole (CMZ, Cefmetazon), MICs of injectable beta-lactam antibacterials including CMZ against clinical isolates from 15 medical institutions all over Japan are measured yearly and the incidence rates of resistance in various species are also evaluated. In the first surveillance from June 2000 to March 2001, 574 isolates of 13 species were tested, 548 isolates of the same 13 species were tested in the second surveillance from April 2001 to March 2002, and 654 isolates of the same 13 species were tested in the third surveillance from April 2002 to March 2003. No remarkable changes in the activity of CMZ were observed in these surveillances spanning three years. The activity of CMZ in this study was comparable to that in the studies conducted before Cefmetazon was launched. This result suggests that CMZ still maintains potent activity. Changes in percent resistance of each species to CMZ (MIC of CMZ > or = 32 microg/ml) were as follows: methicillin-susceptible Staphylococcus aureus (MSSA, 0.0% --> 0.0% --> 0.0%), methicillin-resistant Staphylococcus aureus (MRSA, 72.9% --> 87.2% --> 88.7%), Staphylococcus epidermidis (18.5% --> 31.6% --> 14.3%), coagulase-negative Staphylococcus spp. (CNS, 13.3% --> 18.2% --> 21.4%), Escherichia coli (3.6% --> 0.8% --> 2.1%), Klebsiella pneumoniae (3.4% --> 3.8% --> 2.1%), Klebsiella oxytoca (0.0% --> 0.0% --> 0.0%), Proteus mirabilis (2.3% --> 2.1% --> 0.0%), Proteus vulgaris (13.6% --> 6.7% --> 0.0%), Morganella morganii (7.3% --> 0.0% --> 14.0%), Providencia spp. (12.5% --> 0.0% --> 18.2%), Peptostreptococcus spp. (0.0% --> 0.0% --> 0.0%), Bacteroides fragilis (10.3% --> 10.8% --> 17.1%), Bacteroides spp. (78.6% --> 87.5% --> 62.5%). The Change in percent resistance of MRSA, other CNS, and B. flagiris tended to increase. It is necessary to pay much attention to trends observed in these species. Compared to other drugs tested, against MSSA, the activity of CMZ was inferior to that of CEZ

In this model, scatter between slip and rupture aspect ratio is related to differences in CEZ lengths, and model predictions are consistent with CEZ lengths estimated from 3-D slip distributions of four major earthquakes. The observations require large values of driving stress (˜100 MPa) and small stress drops (˜1 MPa), consistent with a partial stress drop model for earthquakes.

    Tick occurrence was studied in the Chernobyl exclusion zone (CEZ) during the August-October 2009-2012. Dermacentor reticulatus ticks were collected using the flagging method and then screened for infection with Anaplasma phagocytophilum and Babesia canis by a PCR method incorporating specific primers and sequence analysis. The prevalence of infection with B. canis canis and A. phagocytophilum was found to be 3.41% and 25.36%, respectively. The results present the first evidence of B. canis canis and A. phagocytophilum in questing D. reticulatus ticks from the Chernobyl exclusion zone. They also reveal the presence of tick-borne disease foci in areas with no human activity, and confirm that they can be maintained in areas after a nuclear disaster with radioactive contamination.

    The Czech Republic is almost the only country in the central Europe which continues with the construction of nuclear power reactors. Its small territory and dense population causes public worries concerning the disposal of the spent nuclear fuel. The Czech nuclear scientists and the power companies and the nuclear industries are therefore looking for alternative solutions. The Los Alamos ATW project had received a positive response in the Czech mass-media and even in the industrial and governmental quarters. The recent scientific symposium {open_quotes}Accelerator driven reactors and nuclear waste management{close_quotes} convened at the Liblice castle near Prague, 27-29. 6. 1994 and sponsored by the Czech Energy Company CEZ, reviewed the competencies and experimental basis in the Czech republic and made the first attempt to formulate the national approach and to establish international collaboration in this area.

    Commercially available titanium alloys as well as emerging titanium alloys with limited or no production experience are being considered for a variety of applications to high speed commercial aircraft structures. A number of government and industry programs are underway to improve the performance of promising alloys by chemistry and/or processing modifications and to identify appropriate alloys and processes for specific aircraft structural applications. This paper discusses some of the results on the effects of heat treatment, service temperatures from - 54 C to +177 C, and selected processing on the mechanical properties of several candidate beta and alpha-beta titanium alloys. Included are beta alloys Timetal 21S, LCB, Beta C, Beta CEZ, and Ti-10-2-3 and alpha-beta alloys Ti-62222, Ti-6242S, Timetal 550, Ti-62S, SP-700, and Corona-X. The emphasis is on properties of rolled sheet product form and on the superplastic properties and processing of the materials.

    In radioecology, the need to understand the long-term ecological effects of radioactive contamination has been emphasised. This requires that the health of field populations is evaluated and linked to an accurate estimate of received radiological dose. The aim of the present study was to assess the effects of current radioactive contamination on nematode assemblages at sites affected by the fallout from the Chernobyl accident. First, we estimated the total dose rates (TDRs) absorbed by nematodes, from measured current soil activity concentrations, Dose Conversion Coefficients (DCCs, calculated using EDEN software) and soil-to-biota concentration ratios (from the ERICA tool database). The impact of current TDRs on nematode assemblages was then evaluated. Nematodes were collected in spring 2011 from 18 forest sites in the Chernobyl Exclusion Zone (CEZ) with external gamma dose rates, measured using radiophotoluminescent dosimeters, varying from 0.2 to 22 μGy h(-1). These values were one order of magnitude below the TDRs. A majority of bacterial-, plant-, and fungal-feeding nematodes and very few of the disturbance sensitive families were identified. No statistically significant association was observed between TDR values and nematode total abundance or the Shannon diversity index (H'). The Nematode Channel Ratio (which defines the relative abundance of bacterial- versus fungal-feeding nematodes) decreased significantly with increasing TDR, suggesting that radioactive contamination may influence nematode assemblages either directly or indirectly by modifying their food resources. A greater Maturity Index (MI), usually characterising better soil quality, was associated with higher pH and TDR values. These results suggest that in the CEZ, nematode assemblages from the forest sites were slightly impacted by chronic exposure at a predicted TDR of 200 μGy h(-1). This may be imputable to a dominant proportion of pollutant resistant nematodes in all sites. This might

    Twenty-eight drugs, including cephem antibiotics and anti-inflammatory agents currently used or considered potentially useful in neonatal intensive care nurseries in Japan, were examined to determine their influence on albumin and bilirubin interaction by means of a glucose oxidase - peroxidase method, using an automated analyzer (Arrows) for unbound bilirubin (U.B.). The apparent binding constant for drugs to the high-affinity site on albumin (KD) was determined. Of cephem antibiotics, latamoxef sodium (LMOX) and cefazolin sodium (CEZ) were found to displace bilirubin from albumin (KD = 5.9 x 10(3) M-1 and 4.5 x 10(3) M-1, respectively) as strongly as Na salicylate (KD = 6.8 x 10(3) M-1). Mephenamate and indomethacin, which are used for medical closure of patent ductus arteriosus in premature infants, were also found to be stronger bilirubin displacers (KD = 1.3 x 10(5) M-1 and 1.2 x 10(5) M-1, respectively) than sulfisoxazole (KD = 1.6 x 10(4) M-1). Maximal displacement factors (MDF's) were also estimated in reference to protein binding (%) and effective serum concentration (M) of each drug in human adults. Of these drugs, mephenamate showed a higher risk of bilirubin displacement (MDF = 3.79) than sulfisoxazole (MDF = 2.58) and LMOX had a higher risk of displacement (MDF = 1.97) than Na salicylate (MDF = 1.85). On the other hand, indomethacin and CEZ showed minimal effects on displacement at therapeutic levels (MDF = 1.03 and 1.00, respectively). At therapeutic serum levels, mephenamate and LMOX may possess the potential for displacing bilirubin from albumin and increasing the risk of bilirubin encephalopathy, in a manner similar to sulfisoxazole.

    This experiment was carried out, in order to investigate the effect of antibiotics and natural mycotoxin on the hematopoietic stem cells at the normal and inflammatory condition. Adjuvant-treated rats (Aj-rats) are considered as a model of human rheumatoid arthritis. We measured the CFU-C and CFU-E of bone marrow of normal and Aj-rats which were injected with large (1.0 g/kg X 3) and small doses (0.5 g/kg X 3) of ampicillin (ABPC), cefazolin (CEZ), chloramphenicol (CP) and fusarenon-X (F-X). In Aj-rats the number of CFU-C was 1.5 times higher and CFU-E 60% less than normal. Injection of large doses of ABPC enhanced markedly the numbers of CFU-C in Aj-rats and suppressed slightly CFU-E in normal rats. Large doses of CEZ inclined to increase CFU-C and decreased CFU-E in normal and Aj-rats. Injection of small doses of CP tended to increase CFU-C and to decrease CFU-E, and large doses of CP to suppress both CFU-C and CFU-E levels in normal or Aj-rats. F-X, natural mycotoxin suppressed markedly both CFU-C and CFU-E levels of normal rats, and slightly the CFU-E in Aj-rats. These results suggest that one should pay attention to the fact that some doses of antibiotics or natural mycotoxin might be harmful on the bone marrow hematopoietic stem cells.

  13. Electricity industry development trends and the environmental programs in the Czech Republic

    1995-12-01

    The process of industrialization in the Czech Republic, which is more intensive than in other parts of central Europe, has been under way since the mid-nineteenth century. Over the last 40 years, large-scale industrial activity was based on extensive use of domestic primary energy sources, especially brown-coal/lignite. The escalation of this usage inflicted heavy devastation to large portions of industrial zones and, as a result, worsened living conditions through atmospheric pollution and other environmental impacts in large regions of central Europe. The Czech electricity industry and CEZ, a.s. (the nation`s principal electricity generator, responsible for meeting eighty percent of national electricity demand, and operator of the nationwide EHV transmission system) has been challenged to cope with all environmental issues by the end of 1997, in compliance with the strict limits set by the Clean Air Act of 1991, which are comparable to standard implemented in advanced industrial countries. A review of the critical environmental issues is presented and the role of the individual and of the State is analyzed. The approach of CEZ, a.s., towards a better natural environment and its response to legal environment provisions have been incorporated into the company`s development program. It comprises decommissioning the most obsolete fossil-fuel fired power stations; rehabilitation of thermal power plants; supplementing the coal/lignite-fired units selected for future operation with FGD systems and retrofitting them with DENOX equipment; a larger share of nuclear electricity generation after the completion of the Temelin NPP (2 units of 1000MW each) and, last but not least, initiating DSM (demand-side management) programs of energy-electricity savings in the Czech Republic.

    Our goal was to analyze minimum inhibitory concentration (MIC) data for Staphylococcus aureus isolated from surgical infections (SIs) and to look for correlations among the clinically available antimicrobials that were tested. Clinical isolates from SIs were collected by a multicenter surveillance group involving 34 institutions in Japan. During the period April 1998 to March 2007, 312 strains of S. aureus [71 methicillin susceptible (MSSA) and 241 methicillin resistant (MRSA)] were consecutively obtained from these institutions. MIC data for 18 clinically available antimicrobial agents [ABPC, CEZ, CTM, CMX, CPR, FMOX, CFPM, CZOP, IPM, MEMP, GM, ABK, MINO, CLDM, FOM, LVFX, VCM, and TEIC (abbreviations defined in Tables 2 and 3)] against these isolates was analyzed using a principal component analysis (PCA). PCA revealed that four principal components explained 71.1% of the total variance. The first component consisted of major contributions from MEPM and IPM. The second component consisted of major contributions from MINO. These two-first axes, which were strong and explained 54.2% of the total variance, were able to classify the clinical isolates into four clusters. Furthermore, the proportion of the four clusters provided the characteristics of the S. aureus that were clinically isolated at each institute. PCA is a clinically applicable method for analyzing MIC patterns. Such analyses might contribute to the establishment of a practical classification of antimicrobial agents and to the identification of the characteristic antimicrobial resistance patterns at each institute.

    In our department, first-generation cephem (CEZ) are generally administered for 2 days as antimicrobial prophylaxis (AMP) for spinal surgery. However, the incidence of surgical site infection (SSI) has recently increased, particularly cases involving coagulase-negative Staphylococci (CNS) as an etiologic agent. The objective was to elucidate the problems with the current AMP and the risk factors of SSI through a retrospective investigation of affected cases. The subjects were patients who underwent spine surgery at our department between August 2007 and June 2013. The subjects were divided into those who developed SSI (S group) and who did not develop SSI (non-SSI (N) group), patients who developed CNS infection in the S group was subdivided as C group, and the risk factors were investigated. The significance of each factor was analyzed using cross tabulation, and multivariate logistic regression analyses were performed with 22 of the investigation factors as explanatory variables. The incidence of SSI was 2.55%, and the etiologic agent was CNS in 17 patients. Upon comparison between the S and N groups, the presence of 3 or more underlying diseases and blood loss were extracted as significant risk factors. Upon comparison between the C and N groups, emergency surgery and intra- and postoperative steroid administration were extracted as significant risk factors, in addition to the presence of 3 or more underlying diseases and blood loss. The effect of the current AMP using first generation cephem is limited, and reconsideration of the protocol may be necessary.

  10. Aerospace applications of beta titanium alloys

    Boyer, Rodney R.

    1994-07-01

    Beta alloys are beginning to play a significant role in both military and commercial aircraft. Ti-10V-2Fe-3Al forgings, for example, play major roles in the McDonnell Douglas C-17 and the Boeing 777. The attractive properties of Beta-C are increasing the use of titanium, rather than steel, in aircraft springs. Ti-15V-3Cr-3Al-3Sn is subject to increasing usage primarily because of its strip producibility and formability. Beta-21S is gaining importance for high-temperature applications. New alloys such as β-CEZ, SP-700, and Timetal® LCB could become important because of advantageous costs, processing, and/or properties. In the past, the use of beta alloys has largely been driven by their superior properties and weight-savings potential. In the future, cost will become more important. As a result, a greater emphasis will be placed on lower cost alloys and/or taking advantage of the improved processing capabilities of these alloys to minimize final component costs.

Methodik: Im Rahmen einer Literaturauswertung und Inhaltsanalyse wurden Artikel deutscher Autoren aus den Jahren 2004 bis 2013 in sechs internationalen englischsprachigen Fachzeitschriften der medizinischen Ausbildungsforschung analysiert. Um einen Überblick über die deutschen Forschungsaktivitäten in diesem Bereich zu bekommen, wurden alle Projekt- und Originalarbeiten deutscher Erst- und Letztautoren identifiziert und einer tiefergehenden inhaltlichen Analyse unterzogen. Ergebnisse: Insgesamt wurden 10.055 Artikel untersucht. Die Auswertung zeigt, dass zwischen 2004 und 2013 179 Artikel – hiervon 145 Projekt- und Originalarbeiten – deutscher Autoren in den betrachteten Zeitschriften publiziert wurden. Es zeigen sich Schwankungen im Zeitverlauf. Bei den Projekt- und Originalarbeiten handelt sich vor allem um Querschnitt- (27,8%) und randomisierte Kontrollstudien (25,6%) zum Thema „Lehr- und Lernmethoden“ (43,6%). Schlussfolgerung: Seit 2009 zeigt sich ein deutlicher Anstieg der Publikationszahlen deutscher Ausbildungsforscher in internationalen Fachzeitschriften im Vergleich zu den Jahren 2004-2008.

  12. ``Rhizogenesis in vitro'' - as a model to study microgravity biological effects

    NASA Astrophysics Data System (ADS)

    Bulavin, Iliya

    Functioning organisms is based on the physiological and biochemical processes in different tissues and cells. Numerous spaceflight biological experiments have shown the essential changes in cell behavior of multicellular and unicellular organisms in comparison with that on Earth. In our investigations, we used the model “Rhizogenesis in vitro” to study cell differentiation in the root cap and growth zones under clinorotation. Advantage of this model is the possibility to study the influence of clinorotation at the beginning of root initiation de novo and next morphogenetic processes unlike experiments in vivo with embryonal seedling roots formed in seeds. Arabidopsis thaliana plants of wild type and scr mutant (№ 3999 by NASC database) were used. For rhizogenesis induction, rosette leaves with petioles were cut and transferred in Petri dishes on MS medium contained 1/10 of MS mineral salt, without vitamins and hormones. One half of Petri dishes were placed vertically (control), the other - on a slow horizontal clinostat (2 rpm). Anatomical investigation of A. thaliana wild type and scr mutant roots formed de novo showed that formation of root cap and growth zones (meristem, distal elongation zone (DEZ), central elongation zone (CEZ) and mature zone) under clinorotation was similar to that in control. A root cap consists of columella and peripheral cells. In the columella there are meristematic cells, statocytes (graviperceptive cells), and secretory cells. Epidermis, parenchyma, endodermis and central cylinder are distinguished in wild type roots. Unlike a wild type, a cortex of scr mutant was represented by one cell layer which had the parenchyma and endodermis characteristics. A root cap length and width were similar in control and under clinorotation. A cell number in the meristem and DEZ and a length of these growth zones did not differ in control and the experimental conditions. The ultrasructure of cap meristematic cells was typical for cells of this

    The effects of various kinds of antibiotics including tetracycline (TC), chloramphenicol (CP), sodium cephalothin (CET), sodium cefazolin (CEZ), colistin sulfate (CL), colistin sodium methanesulfonate (CL-M), bacitracin (BC), gramicidin HCl (GR), rifampicin sulfate (RFP) and lincomycin (LCM), on the neuromuscular junction (NMJ) were studied by in vitro and in vivo experiments. In in vitro experiments, CL and LCM exhibited a blocking effect on the NMJ in rat phrenic nerve diaphragm preparations, and GR caused a marked increase in muscle contraction. This effect was not affected by administration of eserine or CaCl2. In in vitro experiments with frog sciatica nerve and musculus sartorius preparations, CL and GR induced the appearance of endplate potentials, suggesting blockade of the NMJ. No blocking effect of other antibiotics was observed. In in vitro experiments with the preparations from Rana catesbiana frogs, TC and LCM induced a decrease in the frequency of miniature endplate potentials. In in vivo experiments with rabbit musculus tibialis anterior preparations, CL, TC and LCM exerted a blocking effect soon after administration, but GR and RFP had a late blocking effect. CL, GR, BC and RFP were found not to compete with eserine or CaCl2 in terms of the blocking effect on the NMJ. From the fact that TC did not compete with eserine but did compete with CaCl2 and with KCl as blockers at the NMJ, this blocking effect of TC seems to be due to inhibition of release of acetylcholine (ACh). The fact that LCM competes with eserine indicates that this antibiotic has the same type of action as curare on ACh receptors of the NMJ.(ABSTRACT TRUNCATED AT 250 WORDS)

    The finite ovarian follicle reserve can be negatively impacted by exposure to chemicals including the anti-neoplastic agent, cyclophosphamide (CPA). CPA requires bioactivation to phosphoramide mustard (PM) to elicit its therapeutic effects however; in addition to being the tumor-targeting metabolite, PM is also ovotoxic. In addition, PM can break down to a cytotoxic, volatile metabolite, chloroethylaziridine (CEZ). The aim of this study was initially to characterize PM-induced ovotoxicity in growing follicles. Using PND4 Fisher 344 rats, ovaries were cultured for 4 days before being exposed once to PM (10 or 30 μM). Following eight additional days in culture, relative to control (1% DMSO), PM had no impact on primordial, small primary or large primary follicle number, but both PM concentrations induced secondary follicle depletion (P < 0.05). Interestingly, a reduction in follicle number in the control-treated ovaries was observed. Thus, the involvement of a volatile, cytotoxic PM metabolite (VC) in PM-induced ovotoxicity was explored in cultured rat ovaries, with control ovaries physically separated from PM-treated ovaries during culture. Direct PM (60 μM) exposure destroyed all stage follicles after 4 days (P < 0.05). VC from nearby wells depleted primordial follicles after 4 days (P < 0.05), temporarily reduced secondary follicle number after 2 days, and did not impact other stage follicles at any other time point. VC was determined to spontaneously liberate from PM, which could contribute to degradation of PM during storage. Taken together, this study demonstrates that PM and VC are ovotoxicants, with different follicular targets, and that the VC may be a major player during PM-induced ovotoxicity observed in cancer survivors. - Highlights: • PM depletes all stage ovarian follicles in a temporal pattern. • A volatile ovotoxic compound is liberated from PM. • The volatile metabolite depletes primordial follicles.

    Dem nuklearen Patt zwischen Ostblock und westlichem Staatenbündnis ist es nach weitgehend übereinstimmender Auffassung von Politik und Wissenschaft zu danken, dass der "Kalte Krieg" in der zweiten Hälfte des 20. Jahrhunderts nicht zum weltumfassenden Flächenbrand eskalierte. An der raschen Herstellung dieses Patts waren zwei Dresdner Physiker maßgeblich beteiligt, deren einer im Manhattan-Projekt in den USA gearbeitet hatte und später in England der Spionage für die Sowjetunion und des Verrats des Know-how der Atombombe überführt wurde.

    Komplexe Planungsaufgaben entstehen in vielen Bereichen wie z. B. in der Produktion und Logistik, der Bauplanung oder allgemein im Projektmanagement. Typischerweise werden umfangreiche Projekte in viele einzelne Teilaufgaben zerlegt, die dann zeitlich geplant werden. Das heißt, es wird genau bestimmt wann bzw. in welcher Reihenfolge Aufgaben mit welchen Ressourcen durchgeführt warden sollen. Bei der Planung müssen verschiedenste Reihenfolgeabhängigkeiten zwischen den Vorgängen berücksichtigt werden. Diese Abhängigkeiten können technischer Natur sein oder werden aus sicherheitsrelevanten oder wirtschaftlichen Gründen festgelegt.

    Zielsetzung: Das Berliner Projekt „Interprofessionelles Lehren und Lernen in Medizin, Ergotherapie, Physiotherapie und Pflege“ (INTER-M-E-P-P) verfolgt das Ziel, interprofessionelle Lehrveranstaltungen modellhaft zu entwickeln, zu erproben und in die Curricula der Studiengänge zu implementieren. Methodik: Unter der Leitung einer institutions-, professions- und statusübergreifenden Lenkungsgruppe werden interprofessionelle Lehrveranstaltungen konzipiert, durchgeführt und evaluiert. Spezifisch sind die studentische Partizipation in der Lenkungsgruppe und die Begleitung durch externe Supervision. Die Evaluation integriert die Perspektiven aller am Projekt Beteiligten und kombiniert qualitative und quantitative Methoden. Ergebnisse: INTER-M-E-P-P hat Strukturen zur Kooperation der beteiligten Hochschulen und Studiengänge aufgebaut. Drei Lehrveranstaltungen wurden interprofessionell konzipiert, durchgeführt und evaluiert. Die unterschiedliche curriculare, strukturelle und räumliche Verortung der Studiengänge führt zu einem hohen, ressourcenintensiven Planungs- und Umsetzungsaufwand. Stereotype und Rollenbilder der Planenden können den Prozess erschweren; unter externer Supervision jedoch die professionsspezifischen Blickwinkel erweitern und bereichern.Schlussfolgerung: Eine nachhaltige Implementierung von IPL in die Curricula der Gesundheitsstudiengänge ist derzeit durch Barrieren wie die räumliche Trennung und verschiedene Studien- und Prüfungsordnungen erschwert. Sie benötigt dauerhafte Unterstützungsstrukturen auf hochschulischer und politischer Ebene.

Neben unterschiedlichen konzeptionellen Ausrichtungen haben sich mit der Zeit verschiedene Berufsbezeichnungen etabliert. Die Ergebnisse der Delphi-Studie ergaben, dass die Bezeichnung «Family Nurse» (46,3 %) bevorzugt wird, als Hauptaufgaben werden Gesundheitsförderung und Präventionsarbeit betrachtet (85,8 %). Aus diesem Grund sehen die befragten ExpertInnen den Bedarf einer spezialisierten Ausbildung auf Bachelorniveau (81,5 %). Schlussfolgerung: Das Projekt verdeutlicht das Streben der Länder nach einer hochwertigen familialen Versorgung, die durch ein einheitliches FHN-Konzept nachhaltig unterstützt werden könnte.

  2. Kinetic features of gravicurvature of pea (Pisum sativum) and cress (Lepidium sativum) roots

    NASA Astrophysics Data System (ADS)

    Polishchuk, O. V.

    The upper sides of roots oriented horizontally grow more rapidly than the lower sides, causing the root ultimately to grow downward; this phenomenon is known as positive gravitropism. This ability is based on implicit mechanism which is being extensively investigated. Elaborate analysis of kinetic features of gravicurvature may complement the investigation. Pea and cress roots have positive gravitropism as roots of majority of higher plants. Mainly we investigated dependence of gravicurvature angle on time of gravistimulation. Two-day-old seedlings of cress (Lepidium sativum L. cv. P896) and four-day-old pea ones (Pisum sativum L. cv. Damir-2) were placed on 1% agar medium in Petri dishes and turned on angle of gravistimulation. Then they were photographed at the same position each hour of gravistimulation. Photographs were analyzed with the help of Image Tool software program. Both pea and cress roots showed two phases of gravitropic response during gravistimulation for 6 hours when the initial angle of gravistimulation was 135 degrees. Two peaks of the rate of bending were observed. In cress roots, the first peak was much lower and the distance between the two peaks was greater than in pea roots. Curves of gravitropic bending of cress roots grown in agar had one or two inflections while in the case of roots grown on filter paper curves had no inflections. These data are in agreement with the effect of the external medium on the gravitropic curvature of rice roots reported by Staves et al. (1997). Our results may reflect the fact that at least two systems that contribute to gravicurvature may exist in roots. These systems may be ligand-receptor complexes that may be formed with different kinetics in two different regions of the root. The most probable ligand is auxin and the regions appear to be central elongation zone (CEZ) and distal elongation zone (DEZ), that were reported to be centers of tropic bending in roots. Thus, dependence of rate of root bending on

    Bulk metallic nickel is a poor catalyst for the reforming of oxygenates being deactivated by the deposition of coke. In contrast, Ni-ceria is an active system for the catalytic extraction of H2 from the ethanol steam reforming reaction (ESR, C2H5OH + 3H2O ↔ 2CO2 + 6H2). Numerous studies, with model (well-defined crystal surfaces) and technical (high surface area powders) catalysts, have been devoted to understand the fundamental role of each catalyst component, the performance of adjacent sites in the metal-oxide interface, and the complex mechanistic steps that convert two oxygenated reactants (ethanol and H2O) into H2. The size and lowmore » loading of Ni on ceria facilitate metal-oxide support interactions that probably enhance the reactivity of the system. To establish the precise role of both Ni and Ce is challenging. However it is clear that both Ni and Ce are associated with the dissociation of H2O (OH + H), while ceria readily adsorbs and partially dissociates ethanol (i.e. ethoxy formation). The most difficult step of Csingle bondC bond dissociation likely occurs only on Ni or at the Ni-Ce interface. H2O and OH remain as important agents for the prevention of excess C build up during the Csingle bondH/Csingle bondC dissociation process. Often, deactivation upon C build up, is a direct result of Ni sintering and decoupling of the Ni-Ce interactions. One strategy to maintain good activity and stability is to protect the Ni-Ce interaction, and this can be achieved through the use of solid solutions (Ce1–xNixO2–y) or by employing stabilizing agents such as W (NixWyCezO2). In this paper, we present and discuss the most recent work for the ESR reaction and show the important role of ceria which participates directly in the reaction and also enhances catalytic activity through metal-support interactions.« less

  5. BaO Planes, not CuO2 Planes, Contain HIGH-TC Superconductivity

    NASA Astrophysics Data System (ADS)

    Dow, John D.; Harshman, Dale R.

    Muon spin rotation (μ+SR) measurements conducted on crystalline YBa2Cu3O7 are consistent with s-wave pairing, not d-wave, suggesting that the superconducting hole condensate resides in the BaO layers, not in the cuprate-planes. The specific heat and thermal conductivity data are explained by the superconducting BaO layers alone, unlike the failed interpretation based on CuO2-plane superconductivity. The layer charges of the CuO2 planes are almost -2 |e|, indicating that those planes are primarily carriers of electrons, not holes. The cuprate-planes are not the dominant hole-carriers of high-TC superconductivity, as demonstrated by doped YBa2RuO6, which has no such CuO2 lanes, yet superconducts at ~ 93 K. Moreover the trio of related compounds, YSr2RuO6 (doped with Cu on Ru sites), undoped GdSr2Cu2RuO8, and undoped Gd2-zCezSr2Cu2RuO10 all start superconducting near 49 K in their SrO layers, not in the cuprate planes of the two compounds that have such planes, because those planes are either antiferromagnetic or weakly ferromagnetic and so do not superconduct. In PrBa2Cu3O7, a Pr-on-Ba-site (PrBa) defect kills the superconductivity, but Pr-on-Pr-site (PrPr) does not. Both defects are approximately equidistant from the intervening cuprate plane, suggesting that the cuprate plane does not carry significant superconductivity. In GdBa2Cu3O7, Gd-on-a-Gd-site (GdGd) does not break Cooper pairs, but Gd-on-a-Ba-site (GdBa) does, indicating that the superconductivity is in the BaO layers, and not in the cuprate-planes. In HgBa2Can-1CunO2n+2, the BaO layers, not the cuprate-planes, gain positive charge as TC, pressure, and the number of layers n increase. The reason that theories based on holes in the cuprate-planes have done so poorly is that those planes were incorrectly identified as the source of high-temperature superconductivity on the basis of a single datum by Cava et al., that was first contradicted by Jorgensen et al., and then endorsed by Jorgensen alone on the

    Project SUBVENTO is a joint research project of the research facility Technische Universität Braunschweig and the industry partner BBR - Baudis Bergmann Rösch Verkehrstechnik GmbH in close cooperation with the German Federal Agency for Technical Relief (THW). The Project is funded within the European Regional Development Fund (EFRE) allocated by the European Union. Therein an integrated system for the fast and automated remote detection of heat sources using an infrared camera is being developed. For a precise detection of fires or persons a very accurate navigation system including the algorithms and the hardware is required. Furthermore additional sensors like a multispectral camera applicable in small unmanned aerial vehicles (UAVs) should be implemented. Since the mentioned sensor equipment exceeds the current UAVs' payload limit, a new Carolo type aircraft with a wingspan of 3.6 m is designed. It has an increased payload capability and an extended flight time. This is possible due to an optimized aerodynamic layout and a high efficient propulsion system.

Dieser Austausch kann persönlich, aber z.B. auch per Telefon, E-Mail oder durch Computersysteme erfolgen. In diesem Kapitel betrachten wir die persönliche Kommunikation zwischen Vorgesetzten und Mitarbeitern. Zur persönlichen Kommunikation mit Mitarbeitern zählen sowohl formelle Gespräche mit Mitarbeitern als auch eher informelle Gespräche zwischen Tür und Angel. Die Gespräche können dabei mit einzelnen Mitarbeitern (z.B. jährliches Mitarbeitergespräch) oder mit Gruppen von Mitarbeitern (z.B. regelmäßige Projekt- oder Teambesprechungen) stattfinden.

    Der Schwerpunkt dieses Beitrages liegt auf dem Design von Infrastrukturen, welche es ermöglichen sollen, private Daten kontrolliert preiszugeben und auszutauschen. Zunächst wird daran erinnert, dass rechtliche und technische Maßnahmen zum Datenschutz stets auch dazu dienen, den Austausch von Daten zu ermöglichen. Die grundlegende Herausforderung besteht darin, der sozialen und politischen Bedeutung des Privaten Rechnung zu tragen. Privatheit wird aus der Perspektive der Informationsethik dabei als ein normatives, handlungsleitendes Konzept verstanden. Als Maßstab für die Gestaltung der entsprechenden Infrastrukturen wird auf Helen Nissenbaums Konzept der privacy as contextual integrity" zurückgegriffen, um u. a. die Ansätze der end-to-end information accountability" [38] und des Privacy Identity Management for Europe"- Projektes zu diskutieren.

    In dieser Arbeit wird ein Verfahren zur Netzgenerierung und Finite-Elemente-Simulation muskulärer Strukturen vorgestellt. Eine Herausforderung liegt dabei in der Fusion der Simulationsergebnisse mit den Daten histologischer Schnittpräparate. Basierend auf segmentierten histologischen Daten wird eine Rekonstruktion der relevanten muskulären Strukturen mittels eines BCC-Tetraedernetzes initiiert. Dieses wird getriggert über einen Level-Set-Ansatz. Die Deformation des Muskels wird dann mittels eines hyperelastischen Materialgesetzes modelliert und mithilfe der Finite-Elemente-Methode simuliert. Anschließend erfolgt eine Projektion der Ergebnisse der Simulation auf die histologischen Schnittpräparate. Als Anwendungsfall wurden Daten abortiver Feten mit einer Spaltbildung im Bereich der Lippen-, Kiefer- und Gaumenregion herangezogen.

    Methanation plants are important process units in the production of SNG from coal gasification and in the release of heat in the NFE system (Projekt Nukleare Fernenergie - Nuclear Long-Distance Energy Transport Project) EVA-ADAM. In these processes methane is formed from synthesis gases rich in CO, CO/sub 2/ and H/sub 2/; the reaction is exothermic. Within the framework of the joint NFE project involving the Kernforschungsanlage Julich GmbH (KFA) and the Rheinische Braunkohlenwerke AG, supported by the Federal Republic of Germany, methanation processes have been developed and demonstrated in pilot plants at the Kernforschungsanlage Julich GmbH since 1977. Cooperation between the NFE project and H. Topsoe A/S enabled successful test a single-stage methanation process in a catalytic fixed bed at the KFA Julich with the pilot plant IRMA in September 1981.

    The uncertainty in precipitation observations largely influences the performance of rainfall-runoff models. In this study we present first results of a sensitivity analysis that should help to improve our understanding on the impacts on hydrological model simulations of different rainfall datasets that are characterized by variable spatial resolutions. The study area is the well-equipped/observed meso-scale catchment of the Sauer River in the Grand Duchy of Luxembourg. Data used are observations from 15 rain gauges, radar rainfall estimations from the German Weather Service (RADOLAN dataset (Bartels, 2004)) and the Royal Meteorological Institute of Belgium (Wideumont C-band weather radar), as well as the outputs of the regional atmospheric model WRF. In a first step we assess the suitability of the data as forcing datasets specifically for hydrological modelling by analysing and comparing their properties with regard to precipitation climatology, extreme events and rainfall patterns. The radar and WRF grid data are combined with raingauge data by applying the Sinclair-Pegram (Sinclair and Pegram, 2005) radar-gauge merging method. The aim of this analysis is to produce suitable data sets, which can be used in a future step to force various hydrological models based on the FLEX model (Fenicia et al, 2007), a lumped conceptual rainfall-runoff model, with different spatial model structures.

    The bacteria (Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Klebsiella spp. and Pseudomonas aeruginosa) isolated from patients diagnosed as urinary tract infections (UTIs) in 14 institutions in Japan were collected between August 2004 and July 2005. The susceptibilities of these bacteria to various antimicrobial agents were measured. The bacteria were divided into 2 groups consisting of uncomplicated UTIs and complicated UTIs (with and without indwelling catheter) based on their isolation origins. The results were compared with those obtained between 1995 and 2003. The drug sensitivity of S. aureus in this year was similar to those in up to the previous year and S. aureus showed the best susceptibility to vancomycin (VCM) and arbekacin (ABK). The drug sensitivity of E. faecalis in this year also was similar to those in up to the previous year. The susceptibility of E. coli to cephems in this year was generally good and was similar to those in up to the previous year. MIC90 of cefozopran (CZOP) was the most stable and 0.125 microg/mL or less since 1995. The susceptibility of E. coli to cefpirome (CPR) and cefotiam (CTM) also was good but to cefaclor (CCL), cefixime (CFIX), and cefpodoxime (CPDX) was largely decreased in complicated UTI groups. The sensitivity of E. coli to carbapenems also was good but to carumonam (CRMN) tended to decrease. The susceptibility of E. coli to quinolones, however, has largely changed and has decreased since 2003 in uncomplicated UTIs and 2000 in complicated UTIs. That was suggested the development of the resistance to the drug. The susceptibility of Klebsiella spp. to cefazolin (CEZ), CTM, CCL, CPDX, and cefditoren (CDTR) decreased in the previous year and recovered to the year before the previous year in this year. The susceptibility of Klebsiella spp. to other cephems was stable since 1995, especially against CZOP, the highest sensitivity (MIC90: < or = 0.125 microg/mL) was maintained. The susceptibility of

    Einleitung: Vor dem Hintergrund des demographischen Wandels und der Zunahme komplexer Versorgungsanforderungen fordern nationale und internationale Organisationen eine verstärkte Kooperation der Gesundheitsberufe. Die Implementierung von interprofessionellen Lehrangeboten in die Studiengänge der medizinischen, geburtshilflichen, pflegerischen und therapeutischen Berufe ist noch selten. Derzeit werden in Deutschland erste Projekte erprobt. Im vorliegenden Artikel werden die Prozesserfahrungen der Organisatoren bei der Implementierung gemeinsamer interprofessioneller Lehrangebote für sechs Studiengänge dargestellt. Projektbeschreibung: Im Rahmen des Kooperationsprojekts „Interprofessionelles Handeln im Gesundheitswesen“ zwischen der Medizinischen Fakultät der Ruhr-Universität Bochum und dem Department für Angewandte Gesundheitswissenschaften der Hochschule für Gesundheit wurden interprofessionelle Lerneinheiten entwickelt, implementiert und evaluiert mit dem Ziel, langfristige curriculare Ausbildungsstrukturen zwischen den beiden Hochschulen zu etablieren. In vier Lernsequenzen standen die Vermittlung von kommunikativen Kompetenzen, das Wissen und die Wertschätzung gegenüber den Tätigkeitsbereichen der anderen Gesundheitsberufe sowie die Reflexion der eigenen beruflichen Rolle und Verantwortungsbereiche im Vordergrund. Dazu arbeiteten die Studierenden in interprofessionellen Kleingruppen zusammen.Ergebnisse: Insgesamt haben 220 Studierende der Ergotherapie, der Hebammenkunde, der Logopädie, der Medizin, der Pflege und der Physiotherapie an interprofessionellen Kleingruppenseminaren teilgenommen. Bei der Durchführung und Implementierung der Lehrveranstaltungen zeigten sich insbesondere strukturelle und methodische Herausforderungen, die bei der zukünftigen Entwicklung interprofessioneller Lehrangebote berücksichtigt werden sollten. Hierzu zählen die curriculare Einbettung, gemeinsame Zeiträume in den Stundenplänen und räumliche Ressourcen f

    Threats and announcements of homicidal violence at schools may have massive consequences like evacuations, police searches, criminal investigations, or loss of the sense of security by students, teachers, and parents. However, there is a lack of systematic studies about that phenomenon. The present article would like to contribute to closing the research gap. It presents results about the frequency and structure of threats and announcements of homicidal violence in schools in Berlin. The study is based on an official dataset from school administration reports of violent acts in Berlin schools which has been studied within the Berlin Leaking-Projekt. The sample consists of 427 threats and announcements of homicidal violence between 1996 and 2007. The study is an exceptional analysis of the phenomenon: it presents crosscutting results about frequency and characteristics of threats and the threatening students as well as results of a longitudinal analysis about the development of threats and announcements. Results show a rate of 0,3 threats and announcements per 1 000 student and year. During the observation time span a steady increase of threats and announcements – year by year, influenced by imitation effects after school shootings – has been observed.

  16. Radarsensorik

    Winner, Hermann

    Radar ( Radio Detection and Ranging) hat seine Ursprünge in der Militärtechnik des Zweiten Weltkriegs und blieb auch lange an militärische Anwendungen gebunden. Der erste Einsatz im Verkehrsbereich für ein Geschwindigkeitsüberwachungs-system hatte für viele Autofahrer zu eher negativen Erlebnissen geführt. Aber auch für den Fahrer als nützlich empfundene Anwendungen wurden schon früh angedacht, so wie ein Zeitschriftenartikel [1] aus dem Jahre 1955 belegt. In den siebziger Jahren des 20. Jahrhunderts fand ein großes Forschungsprojekt statt, dessen Ziel die Entwicklung von serientauglichen Radarsensoren für den Auffahrschutz war. Zwar hat dieses vom Bundesforschungsministerium geförderte Projekt die Radar-Entwicklung vorangebracht, für einen Serieneinsatz aber war die Zeit noch nicht reif. Erst zwanzig Jahre später waren die technischen Voraussetzungen gegeben, um Radar für die Fahrerassistenz einzusetzen. Im Jahre 1998 war erstmals ein Fahrzeug mit Radar erhältlich. Die Schlüsselfunktion war allerdings nicht die Auffahrwarnung, sondern die Adaptive Geschwindigkeitsregelung ACC (s. Kapitel 32), auch wenn die Auffahrwarnung bei diesem System als Funktionsteil mit integriert war. In kurzen Abständen folgten weitere radarbasierte ACC-Systeme.

    Die Verifikation von digitalen Schaltungen nimmt heutzutage einen bedeutenden Stellenwert ein. In diesem Paper wird ein Weg beschrieben, der die Erstellung und Wartung von funktionalen Testbenches für digitale Designs unterstützt. Für viele Projekte übersteigt der zeitliche Aufwand für das Testen den Aufwand für die Implementierung der Schaltung. In vielen Fällen beträgt der Aufwand für das Testen bereits 70% des Entwicklungsaufwands (Bergeron, 2000). Typischerweise wird die Testbench auch in der gewählten Hardwarebeschreibungssprache (VHDL oder Verilog) implementiert. Diese Sprachen stellen jedoch nicht die beste Wahl für Verifikationsbelange dar. Gründe dafür sind darin zu suchen, dass diese Sprachen wichtige Konzepte aus den Softwaresprachen (wie z.B. Objektorientierung) nicht kennen. Weiters stehen komfortable Softwarebibliotheken (Zufallszahlengenerierung, Stringverarbeitung, etc.) den Hardwaresprachen nicht zur Verfügung. In diesem Paper wird der Einsatz der Programmiersprache Python (PythonHomepage, 2003; Beazley, 2001) für die Verifikation vorgeschlagen, um die benötigte Zeit für die Funktionalen Tests zu reduzieren.

    In nahezu allen elektronischen Geräten dienen leistungselektronische Systeme zur Umformung und Steuerung der notwendigen Spannungen bzw. Ströme. Aufgrund ihrer komplexen Baustrukturen und der häufig geringen Losgrößen werden diese Systeme jedoch hauptsächlich in zeitintensiver Handarbeit gefertigt. Viele Firmen, die sich mit der Montage solcher Systeme auseinandersetzen, entscheiden sich deswegen zu einer Verlagerung der Wertschöpfungsschritte in sogenannte Niedriglohnländer. Im Projekt Wettbewerbsfähige Produktionskonzepte und Montageverfahren für leistungselektronische Systeme in globalen Märkten" (ProMoLeS), das unter dem Themenfeld Kompetenz Montage: Global agieren, am Standort Deutschland montieren" durchgeführt wurde, sind die Ergebnisse entstanden und Lösungen entwickelt worden, welche in den nachfolgenden Kapiteln ein breites Spektrum rund um die Montage leistungselektronischer Systeme abdecken.

  19. What Can Be Learnd From Multiple Ocean-layer Reflections Observed On The Ocean Floor

    Thorwart, M.; Dahm, T.

    An array of seven ocean bottom seismometer (OBS) and seven ocean bottom hy- drophones (OBH) was installed for 5 1/2 month in the Tyrrhenian Sea in the scope of the DFG(German science society)-projekt 'Tyrrhenian Sea'. Ten deep-focus events (between 150 and 300 km) with a hypocenter directly beneath the array were recorded. Multiple PwP-phases in the coda of the P-wave are typical for OBS seismograms and are caused by multiple reflections in the water layer. These echos occur in regular intervals of 2 to 4 seconds depending on the thickness of the water layer. The ampli- tude and the waveform of the PwP-phases are controlled by the impedance contrast between water and sediments and by the structure and thickness of the sediment layer. The onsets show a different pattern of amplitude and polarity on the vertical compo- nent of the seismometer and on the hydrophone . To understand the observed patterns we calculate synthetic time traces by using a sim- plified reflectivity approach. Different velocity and density models show that patterns can be quite variable and complex. We test the effects of the boundary structure, the impedance model and the sediment layer thickness. The goal is to model the observed waveforms simultaneously on the seismometer and the hydrophone and to derive a structural site model.

  20. The effectiveness of individual placement and support for people with mental illness new on social benefits: a study protocol

    PubMed Central

    2013-01-01

    Background In Switzerland, people with a severe mental illness and unable to work receive disability benefits (‘IV-pension’). Once they are granted these benefits, the chances to regain competitive employment are usually small. However, previous studies have shown that individual placement and support (IPS) supports a successful reintegration into competitive employment. This study focuses on the integration of newly appointed IV-pensioners, who have received an IV-pension for less than a year. Method/design The present pilot project ZHEPP (Zürcher Eingliederungs-Pilot Projekt; engl.: Zurich integration pilot project) is a randomized controlled trial (RCT). The 250 participants will be randomized to either the intervention or the control group. The intervention group receives support of a job coach according to the approach of IPS. Participants in the control group do not receive IPS support. Participation takes a total of two years for each participant. Each group is interviewed every six months (T0-T4). A two-factor analysis of variance will be conducted with the two factors group (intervention versus control group) and outcome (employment yes/no). The main criterion of the two-factor analysis will be the number of competitive employment contracts in each group. Discussion This study will focus on the impact of IPS on new IV-pensioners and aims to identify predictors for a successful integration. Furthermore, we will examine the effect of IPS on stigma variables and recovery orientation. Trial registration ISRCTN54951166 PMID:23883137

    Die optimale Auslegung von Infrastrukturen z. B. bei der Verkehrsplanung und bei der Planung von Versorgungssystemen, die optimale Strukturierung bzw. Formgebung von Materialien und Werkstücken z. B. im Leichtbau sind aktuelle Themen angewandter Forschung. In beiden Bereichen wurde bis in die jüngste Zeit vornehmlich eine simulationsbasierte Optimierung auf der Grundlage einer Parameterjustierung vorgenommen, die oft wenig systematisch und zeit- und kostenintensiv ist. Stattdessen erweisen sich modellbasierte mathematische Optimierungsalgorithmen zusammen mit moderner numerischer Simulations-und Visualisierungstechnologie zunehmend als Katalysator neuer Technologien. Eine so verstandene Mathematische Optimierung kann bereits auf beeindruckende Erfolgsgeschichten verweisen und so den Anspruch als eine Zukunftsdisziplin behaupten. Diesem Anspruch trägt die Einrichtung des DFG-Schwerpunktprogramms 1253, Optimierung mit partiellen Differentialgleichungen’ im Jahre 2006 Rechnung, in dem über 25 Projekte im Bundesgebiet sowohl auf die theoretische Fundierung, als auch und insbesondere auf die Verzahnung zwischen Methodenentwicklung und numerischer Realisierung fokussieren.

    Introduction of new advanced electrical connections into a transmission grid reduces the capacity of existing overhead lines (OHLs). At the same time, designing & building of new OHLs and substations involves considerable technical, environmental and economical problems. The authors propose a concept of the multi-objective optimization for selection of transmission line routes, towers (their type, placement and geometry), of conductors, insulators, dampers, earthing and lightning protection systems, span lengths, etc.. The optimization is organized in five stages. At the first and second stages a search for optimum solutions is performed along with determination of the main impacting factors. The next two stages present a two-objective optimization based on Pareto's approach. At the last stage (exemplified by a case study), the probability of the restriction removal conditions is assessed, and preventive measures are identified. The presented approach uses a real line design and is intended for minimizing the total invested capital and maximizing the net present value. In the framework of this approach 20 alternatives have been elaborated, which can successfully be applied in the cases described in the paper.

    Das Projekt "Nationales Krebshilfe-Monitoring zur Solariennutzung" (National Cancer Aid Monitoring of Tanning Bed Use, NCAM) ist eine deutsche Großstudie mit dem Ziel, die wichtigsten Risikofaktoren für Hautkrebs zu beobachten: natürliches Sonnenlicht und künstliche UV-Strahlung. NCAM ist eine bundesweite Querschnittstudie mit zunächst vier Runden der Datenerfassung (sogenannten Wellen) zwischen 2015 und 2018. Jedes Jahr wird eine bundesweit repräsentative Stichprobe aus 3.000 Personen im Alter von 14 bis 45 Jahren befragt. Die Querschnittsbefragung wird durch eine Kohorte von n = 450 aktuellen Solariennutzern ergänzt. Die erste Welle im Jahr 2015 ergab eine Gesamtprävalenz der Solariennutzung von 29,5 %. Elf Prozent aller Teilnehmer hatten in den vergangenen zwölf Monaten ein Solarium genutzt. Zu den Determinanten der aktuellen Solariennutzung gehörten jüngeres Alter, weibliches Geschlecht und Vollzeit-/Teilzeitbeschäftigung. Die hauptsächlichen Beweggründe, die für die Nutzung eines Solariums genannt wurden, waren Entspannung und Attraktivitätssteigerung. NCAM ist weltweit die erste Studie zur Überwachung der Risikofaktoren für Hautkrebs in jährlichen Intervallen anhand einer großen, landesweit repräsentativen Stichprobe. Erste Ergebnisse deuten darauf hin, dass Millionen Deutsche trotz Warnungen der WHO Solarien nutzen, und dass viele dieser Nutzer Jugendliche sind - trotz gesetzlicher Beschränkungen, die das Ziel haben, die Nutzung von Solarien durch Minderjährige zu verhindern. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

    Since January 1994, heroin-assisted treatment for opiate addicts has been available in Switzerland. This is the first report of the long-term effects of this form of treatment. The report examines subjects who entered a study involving medical prescription of opiates (Projekt zur ärztlichen Verschreibung von Betäubungsmitteln; PROVE) in Switzerland between January 1994 and March 1995 (n = 366). Opiates were dispensed in eight treatment centres. A follow-up was conducted 6 years after treatment entry. Two groups were assessed: clients who have continuously been on heroin-assisted treatment since entry into the PROVE study or who re-entered this treatment, and ex-clients who had discontinued heroin-assisted treatment at the time of follow-up. Two kinds of comparisons were conducted. Firstly, conditions at treatment entry were compared to 6-year follow-up outcomes, and secondly, outcomes were compared between clients still on heroin-assisted treatment and those who had been discharged. It was found that 46% of the clients still alive were on heroin-assisted treatment at the time of follow-up. A comparison of the present living conditions showed very little difference between those in treatment and those who had terminated treatment. Compared to the situation at entry, the results of the follow-up showed a significant decrease in the use of illegal substances, illegal income and most other variables concerning social conditions, but they also showed an increase in unemployment and reliance on social benefits. Heroin-assisted treatment is thus efficacious in the long-term course of treatment and is still effective after termination of treatment with respect to living conditions and use of illicit substances.

    The monoclonal antibody rituximab has shown clinical effectiveness in combination with chemotherapy for the treatment of non-Hodgkin's lymphoma (NHL) in several randomized controlled studies. Rituximab maintenance therapy is associated with significant improvement in progression-free and overall survival in patients with NHL. However, treatment with rituximab causes considerable costs for healthcare systems. This article provides an overview of economic evaluations of rituximab and appraises their methodological quality. A systematic literature search of cost-effectiveness studies on rituximab was carried out in nine electronic databases: MEDLINE, EMBASE, Cochrane Database of Systematic Reviews (CDSR), the German Agency of Health Technology Assessment (DAHTA) database, German Institute for Quality Improvement (DIQ)-Literatur, DIQ-Projekte, Database of Abstracts of Reviews of Effects (DARE), Health Technology Assessments (HTA) database and Sozialmedizin (SOMED) [languages: English, German, Dutch, French, Spanish and Italian; publication period: 1998 to 2010]. Based on pre-specified inclusion criteria, cost-effectiveness studies were identified that compared standard chemotherapy with standard chemotherapy plus rituximab in patients with a subtype of NHL. The methodological quality of the studies was assessed using a quality checklist. Fourteen economic evaluations from seven different countries were included in the review. All economic evaluations reported incremental cost-effectiveness ratios (ICERs) for the add-on therapy with rituximab that were below the country-specific thresholds. The studies differed significantly in their characteristics and methodological rigour. Most studies lacked transparency regarding identification and justification of data. In several studies, the rationale for the model structure was not described appropriately. Adding rituximab to standard chemotherapy is considered a cost-effective treatment option for NHL. However, the results of

    Zielsetzung: An der Universität zu Köln wird seit 2009 auf der Basis der Empfehlungen der Association for Dental Education in Europe (ADEE) ein longitudinales Curriculum zur Vermittlung von sozialen und kommunikativen Kompetenzen in der Zahnmedizin (LSK-Dent) entwickelt. Im Rahmen dieses Curriculums wurde überlegt, einen Rezeptionsdienst in den Behandlungskursen der Poliklinik für Zahnerhaltung und Parodontologie zu entwickeln, welcher die organisatorische und administrative Abwicklung der Patienten durch die Studierenden beinhaltet. Durch ihn sollen die Studierenden Einblicke in Praxisabläufe erhalten und er soll als Lernwelt für soziale und kommunikative Kompetenzen fungieren. Dieser Beitrag stellt sowohl das LSK-Dent Projekt als auch die Umsetzung des Rezeptionsdienstes vor und es werden erste Evaluationsergebnisse berichtet. Methodik: Es wurden Patienten (n=575) und Studierende (n=53) mittels Fragebögen befragt. Zusätzlich wurden vier halbstandardisierte Interviews mit Studierenden geführt Ergebnisse: Der Rezeptionsdienst konnte erfolgreich implementiert werden und wird von Patienten und Studierenden gut angenommen. Es zeigen sich erste Hinweise, dass der Rezeptionsdienst von den Studierenden als eine Lernwelt zum Trainieren von sozialen und kommunikativen Fähigkeiten wahrgenommen wird und dass die Studierenden durch ihn einen Einblick in Praxisabläufe erhalten. Schlussfolgerung: Der Rezeptionsdienst stellt eine innovative Ergänzung der bisherigen Behandlungskurse dar und zeigt beispielhaft die Umdeutung bestehender Realitäten in modellierte Erfahrungs- und Lernwelten für Studierende. Inwiefern reflexive Elemente – konzeptionell eingebracht – den subjektiv wahrgenommenen Mehrwert erhöhen können, muss in weiteren Untersuchungen geklärt werden.

    In recent years, South Africa has encountered a critical electricity supply which necessitated the implementation of demand-side management (DSM) projects. Load shifting and energy (EE) efficiency projects were introduced in mining sector to reduce the electricity usage during day peak time. As the compressed air networks and the water pumping systems are using large amounts of the mines' electricity, possible ways were investigated and implemented to improve and optimise the energy consumption and to reduce the costs. Implementing DSM and EE in four different mines resulted in achieving the desired energy savings and load-shifting. W ostatnich latach w Południowej Afryce zanotowano pewne trudności z dostawami energii elektrycznej, co wymusiło wdrożenie działań mających na celu skuteczne zarządzanie zagadnieniami energetycznymi. Wprowadzono działania mające na celu zmianę systemu obciążeń roboczych i bardziej efektywne wykorzystanie energii tak, by obniżyć zapotrzebowanie na energię w trakcie szczytowych godzin w ciągu dnia. Sieci dostarczające sprężone powietrze oraz stacje pomp zużywają znaczne ilości energii w kopalni, przeanalizowano więc możliwe sposoby redukcji i optymalizacji zapotrzebowania na energię i tym samym obniżenia kosztów produkcji. Wdrożenie odpowiednich projektów nakierowanych na oszczędności i optymalizację w czterech kopalniach doprowadziło do oczekiwanych oszczędności energii i umożliwiło zmianę systemu obciążeń roboczych w trakcie procesu produkcji.

    Introduction After the Chernobyl Nuclear Power Plant (CNPP) disaster (04.26.1986) a huge amount (over 2000 sq. km) of nuclear wastes appeared within so-called "Cher- nobyl Exclusion Zone" (CEZ). At present there are not enough storage facilities in the Ukraine for safe disposal of nuclear wastes and hazardous chemical wastes. The urgent problem now is safe isolation of these dangerous wastes. According to the developed state program of radioactive waste management, the construction of a na- tional storage facility of nuclear wastes is planned. It is also possible to create regional storage facilities for hazardous chemical wastes. The region of our exploration cov- ers the eastern part of the Korosten Plutone and its slope, reaching the CNPP. 3D Space-Time Surface Imaging of Geophysical Fields. There are only three direct meth- ods of stress field reconstruction in present practice, namely the field investigations based on the large-scale fracturing tests, petrotectonic and optical polarization meth- ods. Unfortunately, all these methods are extremely laborious and need the regular field tests, which is difficult to conduct in the areas of anisotropic rock outcrops. A compilation of magnetic and gravity data covering the CNPP area was carried out as a prelude to an interpretation study. More than thirty map products were generated from magnetic, gravity and geodesy data to prepare the 3D Space-Time Surface Images (3D STSI). Multi-layer topography and geophysic surfaces included: total magnetic intensity, isostatically-corrected Bouguer gravity, aspect and slope, first and second derivatives, vertical and horizontal curvature, histogram characteristics and space cor- relation coefficients between the gradient fields. Many maps shows the first and sec- ond derivatives of the potential fields, with the results of lineament (edge) structure detection superimposed. The lineament or edges of the potential fields are located from maximal gradient in many directions

    quality management. The above mentioned calculations and mathematical simulations are still assumed mostly being a domain of science and it is not accepted that many analysis and models were already finished to the level of practical routine applicability. Another important problem is missing relation and cooperation between environmental field (where for instance Water Framework Directive is also assumed to be included) and economical and social fields. The regulative and limits are set up in the area of agriculture on one hand, to reach economic goals in food production, but on the other hand, side effects of those measures to water quality protection are not assumed and vice-versa, watershed management measures are mostly not assessed from point of view of the effects on a desired economic field. Already (Van Rompaey et al., 2000) examined the effect of conversion of arable land into peace (conversion mostly to grassland) in agreement with European agricultural policy of food overproduction prevention, on sediment transport into water reservoirs. Based on mathematical simulations and survey between farmers he approved that unimportant increasing of proportion of converted land in certain regions can significantly influence sediment transport and water quality in given catchment. Proposed presentation tends to invoke support of international and interdepartmental cooperation in given fields and to present various possibilities of application of mathematical modeling and GIS assisted analyses on the level of practical and routine applicability for watershed management in various scales.

    Climate change scenario predict for Switzerland increasing summer temperature and decreasing precipitation. In coming decades forests will therefore likely experience more often drought. However, it is not clear to what extent these changes will occur and where in Switzerland they will be most pronounced. Soil-Vegetation-Atmosphere-Transfer (SVAT) models allow to explore likely changes in the water regime of forest under changing climate. Such process models require information of soil physical properties that largely control water storage in forest soils. Spatial information on physical properties of forest soils is currently lacking in Switzerland. Therefore one objective of the project "Soils and water regime of Swiss forests and forest sites under present and future climate BOWA-CH" (http://www.wsl.ch/fe/boden/projekte/bowa_ch/index_EN) was to predict basic physical properties of forest soils at high spatial resolution for the whole Swiss territory. Based on legacy data of about 2000 forest soil profiles, we mapped particle size composition, volumetric content of rock fragments, soil organic carbon (SOC) content and soil density for fixed-depth soil layers (0-10, 10-30, 30-60, ..., 120-150 cm) by robust external drift kriging (Nussbaum et al., 2014). Comprehensive, digitally available information on climate, topography, vegetation and geology were used as covariates for statistical modelling. Preliminary sets of covariates were chosen by LASSO, and the selection was refined by cross-validating the model for the external drift. External validation with 20 % of the data revealed that clay and sand content, soil density and SOC could be predicted with acceptable precision. Predictions of rock fragment content and silt content were less precise, and the developed model failed to spatially predict soil depth. This is unfortunate because soil depth and rock fragment content largely control water storage in soils. Nussbaum, M., Papritz, A., Baltensweiler, A

    Zielsetzung: Das Medizinische Interprofessionelle Trainingszentrum der Medizinischen Fakultät Carl Gustav Carus an der Technischen Universität Dresden bietet seit dem Wintersemester 2014/2015 Lehrveranstaltungen mit interprofessionellen Inhalten an. Die Besonderheit dieser Lehreinheiten besteht darin, dass sowohl studentische TutorInnen der Medizin als auch SchülertutorInnen der Gesundheits- und Krankenpflege gemeinsam die Lehreinheiten betreuen. Die Studie untersucht das subjektive Erleben der TutorInnen während der gemeinsamen Ausarbeitung und Durchführung dieser Lehreinheiten mit dem Ziel, die Effekte der gleichberechtigten Zusammenarbeit auf die Wahrnehmung und Einschätzung der jeweils anderen Berufsgruppe herauszuarbeiten. Methode: Es wurden teilstrukturierte Leitfadeninterviews mit sechs zufällig ausgewählten TutorInnen durchgeführt. Diese werden mittels inhaltlich-strukturierender Inhaltsanalyse ausgewertet.Ergebnisse: Die Ergebnisse zeigen, dass das gemeinsame Arbeiten vor allem bei den studentischen TutorInnen zu einer Reflexion bestehender Einstellungen geführt hat, jedoch wurden die jeweiligen Co-TutorInnen bei beiden Berufsgruppen in unterschiedlichem Grad als Repräsentanten ihrer Profession wahrgenommen. Durch die Bewältigung einer gemeinsamen Aufgabe in einem nicht-klinischen Kontext begegneten sich die Angehörigen der verschiedenen Berufsgruppen auf Augenhöhe, wenngleich die Medizinstudierenden bereits mehr didaktische Erfahrung aufwiesen und somit im Zuge der Erarbeitung und der Umsetzung der Lehreinheiten meist eine Mentoren-Rolle übernahmen. Die SchülertutorInnen waren vorwiegend auf ihre Rolle als TutorIn konzentriert. Hervorgehoben wurde von beiden Berufsgruppen, dass sie vor der Zusammenarbeit mangelnde oder keine Vorstellungen bezüglich des theoretischen Wissens und der praktischen Fertigkeiten der jeweils anderen Berufsgruppe besaßen.

    The last decade has witnessed extensive applications of 3D environmental monitoring with the LiDAR technology, also referred to as laser scanning. Although several automatic methods were developed to extract environmental parameters from LiDAR point clouds, only little research has focused on highly multitemporal near real-time LiDAR (4D-LiDAR) for environmental monitoring. Large potential of applying 4D-LiDAR is given for landscape objects with high and varying rates of change (e.g. plant growth) and also for phenomena with sudden unpredictable changes (e.g. geomorphological processes). In this presentation we will report on the most recent findings of the research projects 4DEMON (http://uni-heidelberg.de/4demon) and NoeSLIDE (https://geomorph.univie.ac.at/forschung/projekte/aktuell/noeslide/). The method development in both projects is based on two real-world use cases: i) Surface parameter derivation of agricultural crops (e.g. crop height) and ii) change detection of landslides. Both projects exploit the "full history" contained in the LiDAR point cloud time series. One crucial initial step of 4D-LiDAR analysis is the co-registration over time, 3D-georeferencing and time-dependent quality assessment of the LiDAR point cloud time series. Due to the high amount of datasets (e.g. one full LiDAR scan per day), the procedure needs to be performed fully automatically. Furthermore, the online near real-time 4D monitoring system requires to set triggers that can detect removal or moving of tie reflectors (used for co-registration) or the scanner itself. This guarantees long-term data acquisition with high quality. We will present results from a georeferencing experiment for 4D-LiDAR monitoring, which performs benchmarking of co-registration, 3D-georeferencing and also fully automatic detection of events (e.g. removal/moving of reflectors or scanner). Secondly, we will show our empirical findings of an ongoing permanent LiDAR observation of a landslide (Gresten

    The constructed Hühnerwasser ("Chicken Creek") catchment is an ecohydrological system in an initial state of development. The catchment with an area of 6 ha was built up from quaternary sediments in the post-mining landscape of Lusatia in Eastern Germany and serves as a critical zone observatory for detecting ecosystem transition. The soil substrate is characterized as sands to loamy sands with low carbonate contents but significant amounts of gypsum in the sediments of the catchment. The catchment undergoes a strong transition from an abiotic system in the initial years to a system with growing influence of biota. Concerning the hydrology, a regime shift from surface runoff to groundwater flow dominated processes is significant. It is of interest, whether the catchment transition is also reflected by hydrogeochemical indicators. We assume gypsum dissolution as dominant process at the catchment scale. In order to investigate the hydrogeochemical evolution of the catchment we analysed electric conductivity, calcium and sulphate concentrations and pH-values of biweekly composite samples from 2007-2013 of the atmospheric deposition, of runoff and soil water. The two observation points in the flowing water represent surface runoff and groundwater discharge respectively. Soil water has been analysed at four soil pits in three depths. The monitoring data were provided by the Research Platform Chicken Creek (https://www.tu-cottbus.de/projekte/en/oekosysteme/startseite.html). From the macroscopic data analysis we found an exponential decay of the electric conductivity, calcium and sulphate concentrations in the flowing waters and some of the soil pits. In the flowing water, the decrease slope of the electric conductivity and the calcium and sulphate concentrations is almost identical. The calcium / sulphate molar ratio as an indicator of gypsum dissolution is almost equal to one up to 2010, afterwards more calcium than sulphate is released. The pH-values in the flowing

    portion of siliclastic input which was documented during the Late Tithonian and Valanginian could indicate tectonic activity combined with rised humidity and with the eustatic sea-level drop (Michalík, 2007). Rapid decrease of oligotrophic nannoconid abundance correlable with the extinction of calpionellids has been interpreted as the Cretaceous first biocalcification crisis (Erba and Tremolada, 2004). Thus, thinning and deformation of calpionellid loricas could have been associated with distant volcanic effusions producing metallic contaminants and salinity variations.

    Einleitung: Die Forschung in der Medizin, wie sie auch im Rahmen des CanMEDS Modell beschrieben wird, genießt einen hohen Stellenwert. Viele Medizinstudierende in Deutschland beginnen schon während des Studiums mit der Arbeit an einem Promotionsprojekt. Eine große Anzahl dieser Projekte wird allerdings oft unvollendet abgebrochen, wodurch unnötig Ressourcen verschwendet werden. Ein Hauptgrund hierfür ist ein Mangel an Informationen über studentische Forschungsprojekte. Projektbeschreibung: Um diesem Mangel entgegenzuwirken, haben wir an der LMU München die jährlich stattfindende Veranstaltung DoktaMed ins Leben gerufen. Die Kombination von medizinischem Fachkongress und Forschungsmesse mit Vorträgen, Poster-Präsentationen und Workshops sowie einer großen Ausstellung der verschiedenen Arbeitsgruppen und Institute der LMU zieht jedes Jahr mehr als 500 Besucher an. Organisiert wird die DoktaMed als Peer-to-Peer-Veranstaltung von einem Team aus etwa 40 Studierenden.Ergebnisse: Eine Bedarfsanalyse vor der Einführung der DoktaMed identifizierte ein Informationsdefizit als eine wichtige Ursache für die hohe Rate abgebrochener Doktorarbeiten. In den jährlichen Evaluationen durch die Besucher der DoktaMed wird die Veranstaltung durchschnittlich mit der Note 2,1 auf einer sechsstufigen Likert-Skala bewertet (n=558, SD=1,06, 1=sehr gut, 6=sehr schlecht). Die Studierenden empfinden ihren Besuch auf der DoktaMed als sinnvoll investierte Zeit und fühlen sich anschließend besser zum Thema Doktorarbeit informiert. Diskussion: Insgesamt sind die Studierenden mit der Veranstaltung zufrieden und fühlen sich besser auf die Doktorarbeitssuche vorbereitet. Dennoch besuchen viele Studierende die Messe aus unterschiedlichen Gründen nicht. Eine Möglichkeit zur weiteren Verbesserung besteht darin, zusätzlich zu den experimentellen Arbeiten, auf die sich die DoktaMed momentan konzentriert, ein breiteres Angebot an klinischen Projekten zu pr

    The author believes that if a designer has performed many design or research works entailing solutions to various problems, it is recommendable to consider and become aware of previously used methods whose application might have been unwitting or instinctive. The outcome of such reflection can be worth describing and recording in order to formulate a set of guidelines useful in the future. Such methods, being intuitive in nature, are often tied to the designer's subconsciousness, thus are rarely expressed in a clear manner. By using own methods a designer can prove that space should be composed in a given way in order to address specific needs and defined objectives. All this is aimed at preventing accidental formation of space. An example of reasoning serving the aforementioned purpose can be found in a method referred to as CQC or Composition Quality Control, the application of which facilitates intentional shaping of an architectural piece of work. Autor uważa uważa, że jeśli projektant ma za sobą wiele prac projektowych lub też prac badawczych, które połączone były z rozwiązywaniem różnych problemów, to warto zastanowić się i uświadomić sobie sposoby, które dotychczas - może nieświadomie lub odruchowo - były stosowane. Wynik refleksji warto opisać i zapisać po to, żeby ująć go w układ wskazań na przyszłość. Metody te, mając charakter intuicyjny, często związane są z podświadomością projektanta, w związku z tym rzadko można spotkać je jako wyrażone w sposób wyraźny. Stosując metody własne można dowieść, że przestrzeń winna być komponowana tak, a nie inaczej dla określonych potrzeb i wytyczonych celów tak, aby jej forma nie była przypadkowa. Przykładem takiego rozumowania jest przyjeta metoda KJK, której zastosowanie pomaga w swiadomym kształtowaniu dzieła architektonicznego.

Fast decrease and successive increase in hub-height wind speed after sunrise, and the formation of nocturnal low level jets will be discussed. For PV, the life cycle of low stratus clouds and fog is crucial. Capturing these processes correctly depends on the accurate simulation of diffusion or vertical momentum transport and the interaction with other atmospheric and soil processes within the numerical weather model. Results from Single Column Model simulations and 3d case studies will be presented. Emphasis is placed on wind forecasts; however, some references to highlights concerning the PV-developments will also be given. *) ORKA: Optimierung von Ensembleprognosen regenerativer Einspeisung für den Kürzestfristbereich am Anwendungsbeispiel der Netzsicherheitsrechnungen **) EWeLiNE: Erstellung innovativer Wetter- und Leistungsprognosemodelle für die Netzintegration wetterabhängiger Energieträger, www.projekt-eweline.de

  6. Shallow landslides: lessons from Sachseln 1997

    2017-04-01

    A retrospective analysis of the heavy rainstorm in 1997 in Sachseln with almost 500 shallow landslides - half of them within forests, the other half in open land - reveals interesting perspectives. A total of 218 of these landslides were comprehensively documented, including 107 events triggered in forests that have been subjected to a more accurate analysis. A preliminary statistical approach based on distribution functions applied to slope inclination α and shear angle Φ' gives rise to the assumption that optimally managed forests have high protection potential - optimally managed in this context means the NaiS standard improved by findings of our project SOSTANAH. NaiS: www.bafu.admin.ch/publikationen/publikation/00732/index.html?lang=de SOSTANAH: www.slf.ch/ueber/organisation/oekologie/gebirgsoekosysteme/projekte/SOSTANH/index_EN Thus, it can be speculated that up to about four-fifths of these landslides could have been prevented, provided the forests fit the corresponding requirements. In an exemplary calculation, only about 80 ha of the investigated forest area (˜400 ha) would have been affected or roughly 20 landslides triggered of the 107 analysed. Given the specific characteristics for sites and improvement in Sachseln, the approximate costs for forest management, starting from an almost uncovered landslide area up to a mature protection forest (120 years), are estimated at about 35'000 CHF ha-1, yielding yearly 300 CHF ha-1 (price basis: 2016). The expected average annual expenditure to sustainably ensure continued existence of optimal protection forests is slightly lower. In the case of Sachseln, this amounts to about 12 Mio CHF for the whole area of 400 ha and a 100-year period (cost estimate by oeko-b, Stans: www.oeko-b.ch). The total damage of the 1997 event in Sachseln, with an estimated return period of 100 years, exceeded 120 Mio CHF. Of course, destruction was not merely caused by or obviously linked to shallow landslides. Nevertheless, from a

    Blasting is one of the most important operations, which has a great technical and economical effect on the mining projects. Criteria such as fragmentation (operation ultimate objective) and ground vibration, flyrock, airblast, etc. (operation side effects) should be considered in the assessment of blasting operation. A suitable pattern should be able to provide both reasonable (required) fragmentation and blasting side effects. In order to evaluate blasting performance, operational research models such as multi attribute decision making technique (MADM) can be applied. Technique for order preference by similarity to an ideal solution (TOPSIS), a branch of MADM, is a strong method for pattern ranking. The other quantitative method which is applied in the evaluation of systems' efficiency is data envelopment analysis (DEA) model. In this paper, an attempt has been made to develop a new hybrid MADM model for selecting the most appropriate blasting pattern in Chadormalu iron mine, Iran. In this regard, DEA method was utilized to select the efficient blast patterns thereafter TOPSIS was used to recognize the most suitable pattern amongst the selected patterns by DEA method. It was concluded that the patterns J, G and B are the most appropriate patterns for blasting operations in the Chadormalu iron mine. Prace strzałowe to jedne z kluczowych operacji w znacznym stopniu determinujące efektywność ekonomiczną wielu projektów górniczych. W planowaniu prac strzałowych uwzględnić należy podstawowe kryteria, takie jak rozdrobnienie skał (ostateczny cel operacji), wibracje podłoża, występowanie rozrzutu skał, i podmuchów powietrza (efekty uboczne). Odpowiedni harmonogram prac zapewnić powinien zarówno odpowiedni poziom rozdrobnienia (wymiary brył) jak i ograniczenie skutków ubocznych prac. Dla oceny skuteczności prac strzałowych zastosować można modele badań operacyjnych, np. modele oparte o wielokryterialną technikę decyzyjną MADM, a technika

    The paper presents the renovation process of the shaft mining building No. 2 situated in the Kłodawa Salt Mine. A technical state of the facility required immediate reinforcement of structural elements, which was confirmed by expertise carried out by the authors. A lack of repairs could be the cause of building damage. The progress of corrosion in some steel profiles of columns or floors was very advanced. The state of the building was rapidly worsening due to the very high salinity of the indoor environment, moisture (building not insulated) and vibrating engines of machinery operating on different floors felt throughout the facility. After carrying out the technical expertise, working plans and specifications, and relevant numerical analysis, the modernization process was realized by the reinforcement or rebuilding of structural elements. Referat przedstawia sposób remontu i naprawy konstrukcji nośnej i obudowy budynku nadszybia nr 2 na terenie Kopalni Soli "Kłodawa". Elementy konstrukcyjne budynku wymagały natychmiastowego wzmocnienia, co potwierdziła ekspertyza wykonana przez autorów. Zaniechanie prac remontowych groziło awarią budowlaną pomimo przeprowadzonej wcześniej w 2002 r. naprawy. Postęp korozji w niektórych profilach stalowych słupów czy stropów był bardzo zaawansowany. Stan obiektu pogarszał się szybko ze względu na bardzo duże zasolenie środowiska, wilgoć (budynek nieocieplony) oraz pracujące na poszczególnych poziomach maszyny wytwarzające duże drgania wyczuwalne w każdym miejscu obiektu. Wykonano ekspertyzę i projekt wykonawczy przed przystąpieniem do prac renowacyjnych. Przeprowadzono stosowną analizę numeryczną budynku uwzględniając w obliczeniach osłabione korozją elementy pomniejszając odpowiednio w modelu ich parametry wytrzymałościowe.

    Flat 2D screens cannot display complex 3D structures without the usage of different slices of the 3D model. Volumetric displays like the "FELIX 3D-Displays" can solve the problem. They provide space-filling images and are characterized by "multi-viewer" and "all-round view" capabilities without requiring cumbersome goggles. In the past many scientists tried to develop similar 3D displays. Our paper includes an overview from 1912 up to today. During several years of investigations on swept volume displays within the "FELIX 3D-Projekt" we learned about some significant disadvantages of rotating screens, for example hidden zones. For this reason the FELIX-Team started investigations also in the area of static volume displays. Within three years of research on our 3D static volume display at a normal high school in Germany we were able to achieve considerable results despite minor funding resources within this non-commercial group. Core element of our setup is the display volume which consists of a cubic transparent material (crystal, glass, or polymers doped with special ions, mainly from the rare earth group or other fluorescent materials). We focused our investigations on one frequency, two step upconversion (OFTS-UC) and two frequency, two step upconversion (TFTSUC) with IR-Lasers as excitation source. Our main interest was both to find an appropriate material and an appropriate doping for the display volume. Early experiments were carried out with CaF2 and YLiF4 crystals doped with 0.5 mol% Er3+-ions which were excited in order to create a volumetric pixel (voxel). In addition to that the crystals are limited to a very small size which is the reason why we later investigated on heavy metal fluoride glasses which are easier to produce in large sizes. Currently we are using a ZBLAN glass belonging to the mentioned group and making it possible to increase both the display volume and the brightness of the images significantly. Although, our display is currently

    from two on-site weather stations (wind direction, wind speed, air temperature, air humidity, insolation, soil temperature, precipitation) were provided by the 'Research Platform Chicken Creek' (https://www.tu-cottbus.de/projekte/en/oekosysteme/startseite.html). Data were combined and multivariate statistical analysis (PCA, cluster analysis, regression trees) were conducted using the R-software to i) obtain statistical indices describing the relevant characteristics of the data and ii) to identify the determining factors for throughfall intensity. The methodology is currently tested and results will be presented. Preliminary evaluation of the image analysis approach showed only marginal, systematic deviation of results for the different software tools applied, which makes the developed workflow a viable tool for canopy characterization. Results from this study will have a broad spectrum of possible applications, for instance the development / calibration of rainfall interception models, the incorporation into eco-hydrological models, or to test the fault tolerance of wireless rainfall sensor networks.

    The objective of this paper was to use the ArcView 3.2 application for spatial modelling of the exploration forms (pits) in the Bykowszczyzna 8 archaeological site. The 3D digital documentation at a specific scale makes possible easy archiving, presentation, and simple spatial analyses of the examined objects. The ArcView 3.2 programme and its extensions (Spatial Analyst and 3D Analyst), commonly used as analytical tools in geomorphology, were inventively used for inventory-making in the archaeological site. Traditional field sketches were only a base, which enables entering data into the programme, and don't documentation material in itself as it used to be. The method of data visual ization proposed by the author gives new possibilities for using the GIS platform software. W artykule zaprezentowano projekt wykorzystania aplikacji ArcView 3.2 w modelowaniu obrazu form eksploracyjnych na stanowisku archeologicznym Bykowszczyzna 8.

    The studied karst spring 'Gallusquelle' is located on the Swabian Alb in Southwest Germany. The catchment area of the 'Gallusquelle' measures about 45 km². An average annual discharge of 0.5 m³/s serves drinking water to about 40,000 people via a waterworks. The study is part of the research project 'AGRO' (www.projekt-agro.de). The main objective of the project 'AGRO' is to develop a tool for the process-based risk management of micropollutants and pathogens in rural karst aquifers on catchment scale. As particle related transport could play an important role for micropollutants and pathogens, the characterization of particles in the spring water is one focus of this work. Furthermore we will attempt to correlate physicochemical parameters with the characteristics of particles in the spring water in order to enhance the knowledge of the transport mechanisms within the karst aquifer. For the measurement of the particle concentration and the particle size distribution the CIS 1 (GALAI) was used. The system works in a range of 0.5 to 150 µm with a resolution of at least 0.5 µm. The measurement is based on time-of-transition method using a laser beam. The turbidity was measured with an ULTRATURB PLUS (DR.LANGE) and a Fluorometer (GGUN-FL30, ALBILLIA), both working with scattering light method. To verify these measurements we used a portable turbidimeter (2100P IS PORTABLE TURBIDIMETER, HACH) working with the ratio of the signals from the scattered and the transmitted light. Temperature and electrical conductivity where also measured with the GGUN-FL30, whereby the electrical conductivity was verified with a portable multimeter (HQ 40D, HACH). Discharge, pH, water hardness, anion- and cation concentration, total organic carbon (TOC) and dissolved organic carbon (DOC) were also determined. To characterize the particles, the spring water was filtered onsite and the filter cake was analyzed in the laboratory. For SEM (scanning electron microscopy) including EDAX

    20-30 m below the phreatic surface. The obtained values for specific storage and the assumed values for hydraulic conductivity were then verified with a one-dimensional finite element free-surface hydraulic model under steady-state and transient conditions, again fitting the simulated values to the observed pore water pressure records. Boundary conditions were set to constant head at the foot of the column and to infiltration with seepage face review at the top of the column. The results support the observed values for hydraulic conductivity as obtained from the packer tests with low permeabilities in the intact rock mass (K=2e-8 - 3e-10 m/s) and a higher permeability in rock slide masses (around 2e-6 m/s). Furthermore, the values for specific storage found by convolution could be confirmed. Finally, the complex local hydrogeology of an alpine mountain slope with a large suspended rock slide was investigated with a 2D finite element model under steady state and transient conditions. Preliminary results support the theory of a hydraulic barrier at the base of large rock slides with a perched aquifer above and partially unsaturated conditions below the sliding plane.

  18. Analysis of geodetic and legal documentation in the process of expropriation for roads. Krakow case study

    2013-06-01

    Amendment to the Act on special rules of preparation and implementation of investment in public roads resulted in an accelerated mode of acquisition of land for the development of roads. The decision to authorize the execution of road investment issued on its basis has several effects, i.e. determines the location of a road, approves surveying division, approves construction design and also results in acquisition of a real property by virtue of law by the State Treasury or local government unit, among others. The conducted study revealed that over 3 years, in this mode, the city of Krakow has acquired 31 hectares of land intended for the implementation of road investments. Compensation is determined in separate proceedings based on an appraisal study estimating property value, often at a distant time after the loss of land by the owner. One reason for the lengthy compensation proceedings is challenging the proposed amount of compensation, unregulated legal status of the property as well as imprecise legislation. It is important to properly develop geodetic and legal documentation which accompanies the application for issuance of the decision and is also used in compensation proceedings. Zmiana ustawy o szczególnych zasadach przygotowywania i realizacji inwestycji w zakresie dróg publicznych spowodowała przyspieszony tryb pozyskiwania gruntów przeznaczonych pod budowę dróg. Wydawana na jej podstawie decyzja o zezwoleniu na realizację inwestycji drogowej wywołuje szereg skutków, tj. m.in. ustala lokalizację drogi, zatwierdza podziały geodezyjne, zatwierdza projekt budowlany a także powoduje nabycie nieruchomości z mocy prawa, przez Skarb Państwa lub jednostki samorządu terytorialnego. Przeprowadzone badania wykazały iż w powyższym trybie miasto Kraków nabyło w okresie 3 lat ponad 31 ha gruntów przeznaczonych na realizację inwestycji drogowych.

    Due to immense technological and economic developments, human activities producing greenhouse gases, destructing ecosystems, changing landscapes and societies are influencing the world to such a degree, that the environment and human well-being are significantly affected. This results in a need to educate citizens towards a scientific understanding of complex socio-environmental systems. The OECD programme for international student assessment (PISA - http://www.pisa.oecd.org) investigated in detail the science competencies of 15-year-old students in 2006. The report documented that teenagers in OECD countries are mostly well aware of environmental issues but often know little about their causes or options to tackle these challenges in the future. For the integration of science with school learning and involving young people actively into scientific research Sparkling Science projects are funded by the Federal Ministry of Science and Research in Austria. Within the Sparkling Science Project "FlussAu:WOW!" (http://www.sparklingscience.at/de/projekte/574-flussau-wow-/) scientists work together with 15 to 18-year-old students of two Austrian High Schools over two years to assess the functions and processes in near natural and anthropogenically changed river floodplains. Within the first year of collaboration students, teachers and scientists elaborated on abiotic, biotic and spatial indicators for assessing and evaluating the ecological functionality of riverine systems. After a theoretical introduction students formulated research questions, hypotheses and planned and conducted field work in two different floodplain areas in Lower Austria. From the second year on, students are going to develop qualitative models on processes in river floodplain systems by means of the learning software "DynaLearn". The "DynaLearn" software is an engaging, interactive, hierarchically structured learning environment that was developed within the EU-FP7 project "DynaLearn" (http

    Beobachtungen mit dem MPFS-Instrument am russischen 6m - Teleskop in Selentschuk/Kaukasus sowie mit INTEGRAL/WYFFOS am englischen William-Herschel-Teleskop auf La Palma gewonnen. Ein überraschendes Ergebnis war, daß eins der beiden Objekte falsch klassifiziert wurde. Sowohl die meßbare räumliche Ausdehnung des Objektes als auch das spektrale Erscheinungsbild schlossen die Identität mit einem planetarischen Nebel aus. Mit hoher Wahrscheinlichkeit handelt es sich um einen Supernovaüberrest, zumal im Rahmen der Fehler an gleicher Stelle eine vom Röntgensatelliten ROSAT detektierte Röntgenquelle liegt. Die in diesem Projekt verwendeten Integral-Field-Instrumente wiesen zwei verschiedene Bauweisen auf, die sich miteinander vergleichen ließen. Ein Hauptkritikpunkt der verwendeten Instrumente war ihre geringe Lichtausbeute. Die gesammelten Erfahrung fanden Eingang in das Konzept des derzeit in Potsdam in der Fertigung befindlichen 3D-Instruments PMAS (Potsdamer Multi - Apertur - Spektrophotometer), welcher zunächst für das 3.5m-Teleskop des Calar - Alto - Observatoriums in Südspanien vorgesehen ist. Um die Effizienz dieses Instrumentes zu verbessern, wurde in dieser Arbeit die Kopplung der zum Bildrasterung verwendeten Optik zu den Lichtleitfasern im Labor untersucht. Die Untersuchungen zur Maximierung von Lichtausbeute und Stabilität zeigen, daß sich die Effizienz durch Auswahl einer geeigneten Koppelmethode um etwa 20 Prozent steigern lässt. Popular scientific abstract: Currently there are two different approaches in the observational optical astronomy: On the first hand objects are imaged with cameras, on the other hand spectra are produced. The integral-field-technique is a relatively new way to combine both branches. The object image in the telecopes focus is sampled spatially and each spatial bin assigned to a spectrograph. Hence the object is not only sampled spatially but the spectral component is achieved as a third dimension, so the name 3D-Method. The result

    Analysis of stresses and displacements around underground openings is necessary in a wide variety of civil, petroleum and mining engineering problems. In addition, an excavation damaged zone (EDZ) is generally formed around underground openings as a result of high stress magnitudes even in the absence of blasting effects. The rock materials surrounding the underground excavations typically demonstrate nonlinear and irreversible mechanical response in particular under high in situ stress states. The dominant cause of irreversible deformations in brittle rocks is damage process. One of the most widely used methods in tunnel design is the convergence-confinement method (CCM) for its practical application. The elastic-plastic models are usually used in the convergence-confinement method as a constitutive model for rock behavior. The plastic models used to simulate the rock behavior, do not consider the important issues such as stiffness degradation and softening. Therefore, the use of damage constitutive models in the convergence-confinement method is essential in the design process of rock structures. In this paper, the basic concepts of continuum damage mechanics are outlined. Then a numerical stepwise procedure for a circular tunnel under hydrostatic stress field, with consideration of a damage model for rock mass has been implemented. The ground response curve and radius of excavation damage zone were calculated based on an isotropic damage model. The convergence-confinement method based on damage model can consider the effects of post-peak rock behavior on the ground response curve and excavation damage zone. The analysis of results show the important effect of brittleness parameter on the tunnel wall convergence, ground response curve and excavation damage radius.

    Valstybės siena tarp Lietuvos Respublikos ir Baltarusijos Respublikos yra išorinės Europos Sąjungos sienos dalis, todėl jos demarkavimas yra itin svarbus žingsnis, leidžiantis tinkamai taikyti išorinės sienos apsaugos režimą. Šios sienos demarkavimas truko dešimtį metų - nuo Sutarties dėl valstybės sienos tarp Lietuvos Respublikos ir Baltarusijos Respublikos demarkavimo, kurią pasirašė Lietuvos Respublikos ir Baltarusijos Respublikos Prezidentai, o Lietuvos Respublikos Seimas 1996 m. ratifikavo, iki 2006 metų, kai Mišri demarkacijos komisija pasirašė galutinius šios valstybių sienos demarkacijos dokumentus. Vykstant demarkavimo darbams šalys tarpusavyje derino įvairius juridinius, techninius, praktinius klausimus, susijusius su valstybės sienos ženklinimu, geodeziniais-kartografiniais darbais, pasienio juostos įrengimu, tarpvalstybine darbų kontrole, galutinių sienos demarkacijos dokumentų sudarymu ir kt. Iki šiol Lietuvos rytinė siena niekada nebuvo demarkuota, todėl atliekant delimitavimo darbus sienai nustatyti buvo panaudota nelygiavertė ar nekokybi\\vska kartografinė medžiaga, valstybės siena buvo tapdinama su neai\\vskiais arba nery\\vskiais vietovės kontūrais, kartais ji ėjo vingiuotais lauko ar mi\\vsko keliukais. Žymint valstybės sieną vietovėje kilo korektūros būtinybė. Pakoregavus sumažėjo sienos ženklų statymo ir pasienio juostos įrengimo išlaidų, išvengta nesisteminių sienos linijos vingių, išlinkių, įtraukta natūralios ribos (upės, kanalai, proskynos ir pan.), buvo išsaugoti inžineriniai-techniniai statiniai ir komunikacinė infrastruktūra bei jos priežiūros statiniai, siena sutrumpėjo, tačiau išliko perskirstomų plotų balansas. Pagal šalių suderintą valstybės sienos ženklų išdėstymo projektą vietovėje siena buvo paženklinta laikinaisiais sienos ženklais, vėliau jie pakeisti patvirtintos konstrukcijos nuostoviaisiais ženklais: centriniu (poligonometriniu

    of this paper will help designers with the choice of optimal drilling fluid for drilling horizontal wells in unconventional (shale) gas/oil reservoirs. Równolegle ze stale rosnącym zapotrzebowaniem na prowadzenia prac udostępniających w złożach niekonwencjonalnych notuje się wzrost świadomości społecznej odnośnie zagadnień ochrony środowiska. Piana jako alternatywa dla tradycyjnej płuczki wiertniczej nabiera coraz większego znaczenia w górnictwie otworowym. Wiercenie przy użyciu piany pomogą ograniczać zniszczenia formacji geologicznych, redukuje zużycie wody, pozwala na zminimalizowanie oporów ruchu i momentów obrotowych silników. Ponadto, koszty piany są niższe a jej oddziaływanie na środowisko naturalne jest mniej znaczne niż w przypadku typowych płuczek opartych na olejach syntetycznych używanych w trakcie udostępniania trudnych w eksploatacji złóż, np. gazu łupkowego. Wiercenia odcinków poziomych lub prawie poziomych są już szeroko stosowane a zapotrzebowanie na takie odcinki wrasta, ważnym jest właściwe rozpoznanie problemów związanych z transportem urobku wiertniczego i czyszczeniem otworu w trakcie prowadzenia prac wiertniczych na tych odcinkach przy użyciu piany. Zespól badaczy z uniwersytetu w Tulsa zaangażowanych w projekt badawczy w dziedzinie wiertnictwa (TUDRP) przeprowadził serię eksperymentów mających na celu zbadanie wpływu zmiany kąta nachylenia otworu z 90 na 70 stopni na przebieg transportu urobku wiertniczego z wykorzystanie piany w warunkach podwyższonego ciśnienia i podwyższonych temperatur. Badania eksperymentalne i teoretyczne obejmowały także analizę pozostałych parametrów procesu: jakość piany, natężenie przepływu piany, stężenie polimerów, prędkość obrotowa przewodu wiertniczego. Nie stwierdzono znacznych różnic w stężeniu zwiercin ani utraty ciśnienia wskutek tarcia w trakcie zmiany kąta nachylenia z 90 na 70 stopni. Ponadto, dodatkowy wzrost prędkości ruchu

    The present study explored the effects on therapeutic outcomes of training therapists in brief manualized therapy. As part of the Vanderbilt II project, each of 16 therapists (8 psychiatrists and 8 clinical psychologists) treated 2 moderately disturbed adult patients using his or her customary short-term treatment methods; they then received a year of training in a manualized form of brief dynamic therapy, Time-Limited Dynamic Psychotherapy (TLDP); finally, they administered TLDP to 2 additional patients. It was hypothesized that training would result in improved outcomes generally and that differentially greater improvement would be seen in patients commonly considered less suitable for brief dynamic therapy. Outcome data obtained at termination failed to support either hypothesis. Measurements of interpersonal dependency obtained at a one-year follow-up were consistent with the first hypothesis, but the follow-up data were inconsistent with the second. A systematic review of the 32 posttraining cases suggested that the majority of the therapists had not achieved basic competence at TLDP. Die hier beschriebene Studie untersucht die Wirkungen eines Trainings in manualisierter Kurzzeitherapie auf das Therapierergebnis. Als Teil des Vanderbilt II Projektes behandelten jeweils 16 Therapeuten (8 Psychiater und 8 klinische Psychologen) zwei mittelgradig beeinrächtigte erwachsene Patienten mit den ihnen vertrauten Kurzzeitbehandlungsmethoden. Danach wurden sie über ein Jahr in einer manualisierten Form psychodynamischer Kurzzeittherapie ausgebildet und wandten diese Therapie auf zwei weitere Patienten an. Es wurde angenommen, dass die Ausbildung in besseren Ergebnisdaten, die bei Ende der Therapie erhoben wurden, konnten diese Hypothese nicht bestätigen. Maße für die interpersonale Abhängigkeit zu einem Einjahreskatamnesezeitpunkt waren mit der ersten Hypothese konform, aber inkonsistent mit der zweiten.

    Aromatische Amine und Amide (aAA) sind aufgrund ihrer starken Verbreitung in der menschlichen Umwelt und ihres kanzerogenen Potenzials von groer toxikologischer Bedeutung. Die Kanzerogenität der aAA wird durch die Mutagenität hochreaktiver Stoffwechselprodukte vermittelt, die in zwei sequenziellen katalytischen Reaktionen entstehen. Die erste ist meistens eine N-Hydroxylierung, die oft durch Cytochrom P450 1A2 (CYP1A2) katalysiert wird. Daran schliet sich eine O-Konjugation durch Sulfotransferasen (SULT) oder N-Acetyltransferasen (NAT) an. Die Bioaktivierung ist ein kritischer Parameter für die Übertragbarkeit von Ergebnissen aus Tiermodellen auf den Menschen. Rekombinante in vitro Systeme, die fremdstoffmetabolisierende Enzyme verschiedener Spezies exprimieren, ermöglichen die vergleichende Untersuchung der Bioaktivierung im Menschen und in Versuchstieren. Ziel des Projektes war die Aufklärung der Bioaktivierung der aAA durch humane Enzyme. Im Vordergrund stand die Untersuchung der Rolle humaner SULT in diesem Prozess. Es wurden rekombinante in vitro Systeme, konstruiert, die CYP1A2 und SULT des Menschen koexprimieren. SULT-cDNAs wurden in den Säugerzell Expressionsvektor pMPSV kloniert und in Standardindikatorzellen für Mutagenitätsuntersuchungen (V79 Zellen aus dem Chinesischen Hamster) transfiziert. Das Expressionsniveau von CYP1A2 und SULT wurde mittels Immunblotanalyse und radiometrischen Aktivitätsmessungen charakterisiert. In den rekombinanten Zellen wurden vier aAA als Modellsubstanzen (2-Acetylaminofluoren, 2-Aminoanthracen, 3′-Methyl-4-dimethylaminoazobenzol, 2,4-Diaminotoluol) auf ihre Mutagenität am hprt-Locus hin untersucht.Die aAA waren in Zellen, die keine rekombinanten Enzyme oder lediglich CYP1A2 exprimierten, nicht mutagen. In Zellen, die CYP1A2 und SULT der Subfamilie 1A koexprimierten, erzeugten sie bereits in geringen Konzentrationen klare mutagene Effekte (0,3 µM für 2-Acetylaminofluoren und 3′-Methyl-4

    celu: - wzmocnienie posadowienia zabytkowych obiektów i przeniesienie obciążeń na grunt poniżej dna wykopu; - umożliwienie wykonania wewnętrznego poziomu -1 poprzez pogłębienie części budynku maszynowni (MS-8) o jeden poziom; - zabezpieczenie geotechniczne ścian wykopu w rejonie historycznych budynków, - zapewnienie bezpieczeństwa pracy przez okres realizacji podziemnych części Nowego Muzeum Śląskiego jak również funkcjonowania obiektu po zakończeniu procesu rewitalizacji - konstrukcje oporowe przy budynku magazynu odzieży MS-15 i wieży wyciągowej MS-79 będą pełniły rolę docelowych ścian segmentów podziemnych. W artykule zwrócono uwagę na zróżnicowaną budowę geologiczną w rejonie inwestycji, różne obciążenie naziomu, a przede wszystkim na niepewność podłoża i masywu ze względu na wcześniej prowadzone roboty górnicze. Prowadzona przez 176 lat podziemna eksploatacja złóż węgla kamiennego spowodowała osłabienie masywu poprzez m.in. występowanie wkładek węgla kamiennego i stref uskokowych oraz prawdopodobnie starych zrobów. W zależności od rodzaju obiektu będącego przedmiotem zabezpieczenia, jak również konieczności dostosowania technologii zabezpieczenia do zastanych warunków zastosowano kilka rodzajów konstrukcji takich jak palisady czy też bariery mikropalowe stabilizowane kotwiami lub gwoździami. Z uwagi na charakter prac zabezpieczających, dokładność rozpoznania geologiczno-inżynierskiego oraz skalę zadania, projekt zabezpieczeń geotechnicznych miał charakter aktywny. Oznacza to, że rozwiązanie projektowe dostosowywano na bieżąco do faktycznie napotkanych warunków geologicznych. Ponadto podczas realizacji wszystkich prac zabezpieczających wykonywany był monitoring geotechniczny. Ze względu na zabytkowy charakter obiektów sąsiadujących z wykopem konieczny był również monitoring ich konstrukcji. Przedsięwzięcie realizowane jest przy wparciu Europejskiego Funduszu Rozwoju

    Among the main directions of works on energy acquisition, there is the development and application of the technology of underground gasification of coal deposits (UCG). During the process of deposit burning and oxidation, there is also impact of temperatures exceeding 1000°C on rocks surrounding the deposit. As a result of subjecting carboniferous rocks to high temperatures for a prolonged period of time, their structure will change, which in turn will result in the change of their physical properties. Due to the project of underground coal gasification, as performed in Poland, laboratory tests are currently under way to a broad extent, including physical properties of carboniferous rocks subjected to high temperatures. The article presents results of laboratory tests of rocks surrounding the designed geo-reactor: changes to bulk density, specific density and porosity due to high temperature, and confronts the above results with the results of tests of thermal conductivity, specific heat and heat diffusivity (temperature conductivity) of the rocks. The mineralogical investigations were presented too. Jednym z głównych kierunków prac nad pozyskiwaniem energii jest opracowanie i zastosowanie technologii podziemnej gazyfikacji pokładów węgla. W czasie procesu spalania i utleniania pokładu dochodzi również do oddziaływania temperatur przekraczających 1000°C na skały otaczające pokład. W wyniku poddania skał karbońskich wysokim temperaturom przez dłuższy okres czasu będzie dochodzić do zmian ich struktury, co z kolei spowoduje zmiany ich właściwości fizycznych. Ze względu na realizowany w Polsce projekt podziemnego zgazowania węgla prowadzone są obecnie badania laboratoryjne w szerokim zakresie, m.in. właściwości fizycznych skał karbońskich poddanych wysokim temperaturom. W artykule przedstawiono wyniki badań laboratoryjnych skał otaczających projektowany georeaktor: zmian gęstości objętościowej, gęstości właściwej i porowato
