    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.

  3. Activities of CEZ Inc. and improvement of the environment

    1995-12-01

    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.

    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.

    2014-01-01

    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

  18. 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

    NASA Astrophysics Data System (ADS)

    Bołoz, Łukasz

    2013-12-01

    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.

  19. 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.

    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.

    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.

    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

    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.

    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.

  8. 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

    Background 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. Methodology/Principal Findings 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. Conclusions/Significance 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. PMID:27341104

    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

    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

    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.

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

    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.

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 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.

    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

    Zielsetzung: Ausgangspunkt des vorliegenden Artikels ist die Feststellung, dass es aus Deutschland im Vergleich zu den angloamerikanischen Ländern oder den Niederlanden vor 2004 kaum internationale Publikationen im Bereich der medizinischen Ausbildungsforschung gab. In den letzten Jahren wurde jedoch eine steigende Bedeutung der medizinischen Ausbildungsforschung im deutschen Raum deutlich. Zielsetzung dieses Beitrags ist es zu prüfen, inwieweit sich in internationalen, englischsprachigen Fachzeitschriften im Themenfeld „Medizinische Ausbildungsforschung“ seit 2004 eine solche Entwicklung durch eine gesteigerte Publikationsaktivität belegen lässt. 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.

    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.

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

    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

    1986-04-01

    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.

    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.

Aus diesem Grund werden im internationalen Projekt «Family Health Nursing in European Communities» ein einheitliches Ausbildungskonzept für die Family Health Nurse entwickelt. Ziel: Ziel war es, die unterschiedlichen Voraussetzungen in den beteiligten Ländern darzustellen und aktuelle Problemfelder auf Länder- und EU-Ebene zu verdeutlichen. Methode: Hierzu wurden ein Review über grundlegende und länderspezifische Informationen, eine Delphi-Studie, eine Kompetenz- und Anforderungsanalyse und eine Übersicht über vorhandene Aus- und Weiterbildungskonzepte mit FHN-ExpertInnen aus den Projektländern durchgeführt. Ergebnisse: Die Ergebnisse des Reviews spiegeln auch im internationalen Kontext deutliche Unterschiede im Grad der Implementierung des FHN-Konzeptes wieder. 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.

  18. Elucidating the interaction between Ni and CeOx in ethanol steam reforming catalysts: A perspective of recent studies over model and powder systems

    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 C—H/C—C 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 study, 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

  19. 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

    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.

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

    NASA Astrophysics Data System (ADS)

    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.

    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.

    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.

    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.

    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.

    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.

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.

  16. Mapping physical properties of Swiss forest soils by robust external-drift kriging from legacy soil data

    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

    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

    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 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.

    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

    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.

    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

    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. Na tej podstawie zaproponowano stosowne wzmocnienia. Zastosowano technologie wzmocnień stosując wymianę profili stalowych, wspawywanie dodatkowych profili lub blach

    nighttime to well mixed conditions during the day presents a big challenge to NWP models. 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

    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

    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

  14. SOLIDFELIX: a transportable 3D static volume display

    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

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.

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

    Trembecka, Anna

    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.

    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.

    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. Analiza naprężeń i przemieszczeń powstałych wokół otworu podziemnego wymagana jest przy szerokiej gamie projektów z zakresu budownictwa lądowego, inżynierii górniczej oraz naftowej. Ponadto

    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.

    Ziel: Das Ziel dieses Projektes war es, die Qualität und Quantität der Erstantragstellung auf zustimmende Bewertung einer klinischen Prüfung gemäß § 7 der deutschen GCP-Verordnung (GCP-V), die Qualität des Bewertungsverfahrens bei den Ethik-Kommissionen (EKs) in Deutschland sowie das Muster der Einwände seitens der EKs in ihren mit Gründen versehenen Bewertungen (Bescheide) zu evaluieren. Um etwaige Veränderungen über die Zeit zu identifizieren, wurden außerdem die Ergebnisse dieser Umfrage, mit den Ergebnissen einer in 2008 durchgeführten Umfrage verglichen.Methoden: Auf der Grundlage von Bescheiden der für den Leiter der klinischen Prüfung jeweils zuständigen (federführenden) EK in 2011, wurde eine schriftliche Umfrage bei Mitgliedsunternehmen des Verbandes Forschender Arzneimittelhersteller e.V. (vfa) in 2012 durchgeführt. Die erhaltenen Antworten zu dem Fragebogen wurden deskriptiv ausgewertet. Da der in 2011 erhaltene Datensatz mit dem Datensatz in 2007 strukturell identisch war, wurden beide Umfragen miteinander verglichen.Ergebnisse: Von den 24 Unternehmen, die im vfa-Unterausschuss Klinische Forschung/Qualitätssicherung vertreten sind, nahmen 75% (18) an der Umfrage teil. Der Auswertung dieser Umfrage liegen insgesamt 251 Antragsverfahren dieser 18 Unternehmen bei 43 EKs zugrunde. Diese stellen rund 21% der 1.214 bei den Bundesoberbehörden (BfArM und PEI) 2011 gestellten Anträge auf Genehmigung kommerzieller und nicht-kommerzieller klinischer Prüfungen der Phasen I–IV dar.Im Vergleich zu 2007 wurden 2011 eine geringere Zahl von Anträgen (n=251 in 2011 vs. n=288 in 2007) bei einer geringfügig größeren Zahl an EKs (43 in 2011 vs. 40 in 2007) gestellt. Die Anzahl der Einwände stieg um 21% von 1.299 (2007) auf 1.574 (2011) und damit im Durchschnitt von 4,5 (2007) auf 6,3 (2011) Einwände pro Antrag. Insgesamt gesehen zeigt die Analyse der formalen und inhaltlichen Einwände ein Muster auf, das der vorangegangenen Umfrage sehr

    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
