Full Text Available Mortality and feeding inhibition effects of several plant extracts collected from Merauke Distric, Papua against Crocidolomia pavonana (F. larvae (Lepidoptera: Crambidae. The objective of this research was to study mortality and feeding inhibition effects of several plants extract species collected from Merauke District Papua as botanical insecticides against Crocidolomia pavonana larvae. Seven plants used in the research were Areca catechu seeds (Arecaceae, Eucalyptus pellita tree barks (Myrtaceae, Myrmecodia pendans tubers (Rubiaceae, Piper aduncum fruits (Piperaceae, Piper betle leaves (Piperaceae, Pandanus conoideus fruits (Pandanaceae, and Zingiber officinale rhizomes (Zingiberaceae. Each plant extract was tested to 2nd instar C. pavonana larvae. The insecticidal activities were assessed including mortality and feeding inhibition activities. Extract concentrations for mortality tests using topical application method were 0,1%, 0,5%, 1%, 2%, and control, while extract concentrations for feeding inhibition tests using choice and no choice methods were 0,25%, 0,5%, 1%, 2%, and control. Each treatment was introduced to ten C. pavonana larvae and replicated five times. The results showed that P. aduncum and P. conoideus fruits extracts gave 100% mortality at 2% rate. Extract of P. betle leaf at 2% rate totally inhibited feeding activity of larvae (100% using choice method, while extract of Z. officinale rhizome at 2% rate resulted in moderate feeding inhibition effect (75% using no choice method.

Full Text Available The objective of this study was to evaluate the insecticidal activity of bark extracts of 35 plant species belonging to four families (Clusiaceae, Lecythidaceae Meliaceae, and Sapindaceae against the cabbage head caterpillar Crocidolomia pavonana. Extraction of the test plant materials were performed with maceration method using ethanol and methanol continued by counter-current distribution separation in ethylacetate and water. Bark extract preparation of each plant species was tested against C. pavonana larvae by leaf-feeding method at concentration of 0.25% and 0.5%. Second-instar C. pavonana larvae were fed extract-treated broccoli leaves for 48 hours, then were presented with untreated leaves until the surviving larvae reached the fourth-instar larvae. The number of dead larvae was recorded. The phytochemical test of bark extract of Calophyllum soulattri was done by qualitative method. The results showed that the bark extracts of C. soulattri (Clusiaceae, Barringtonia sarcostachys (Lecythidaceae, and Aglaia tomentosa (Meliaceae exhibited good insecticidal activity. Methanol extract of C. soulattri barks possessed strong insecticidal activity against C. pavonana larvae with LC95 of 0.21%. This extract showed positive response in alkaloid and triterpenoid qualitative tests. Further studies are needed to identify insecticidal compounds in those active extracts.

Full Text Available Plant extracts have been known to cause physiological and biochemical interferences against insect, such as feeding inhibitor, food assimilation, and changes on activity of cytochrome b5 and cytochrome P450. This study was carried out to examine the effect of the extracts mixture of Tephrosia vogeliiand : Piper aduncum (1 : 5 on the physiology of Crocidolomia pavonana (F. as well as extract of P. aduncum on biochemical of C. pavonana. The study showed that larvae of C. pavonana was experiencing a feeding inhibition until 94.82% after treated with extracts mixture on concentration 0.06% or equivalent to LC95. However, larvae treated with extracts mixture on LC25 and LC50 only experienced a relative growth disorders as a result of intrinsic toxicity of extracts mixture which enters into the body of insects. Insect adaptation to toxic plant compounds indicated by an increase in the digestibility of larvae approximately 11.11%. Furthermore, detoxification mechanism by larvae against active compounds of P. aduncum occured and shown by an increase of oxidative enzyme activity of cytochrome b5 and cytochrome P450, in in vivo and in vitro compared to control. This study provides an information about mode of action of extracts mixture of T. vogelii and P. aduncum (1 : 5 on larvae of C. pavonana and detoxification mechanism by larvae due to extract of P. aduncum

Full Text Available Eriborus argenteopilosus is the most important parasitoid attacking cabbage pest Crocidolomia pavonana in Indonesia. Previous studies proved that parasitoid encapsulation was found to be an important factor limiting the effectiveness of the parasitoid in controlling pest population in the field. Since 1998, we have conducted series studies to investigate encapsulation mechanism developed by hosts against parasitoid, responses of parasitoid toward encapsulation ability and to determine factors that may help parasitoid avoid encapsulation. Parasitoid responses were examined on two different hosts C. pavonana and Spodoptera litura. Our findings showed that parasitization level was found to be high both on C. pavonana and S. litura. Encapsulation occurred to be high in all larva stages of C. pavonana, in contrast encapsulation was recorded very low in all larvae stages of S. litura. We recorded that encapsulation in the larval body of C. pavonana was completed in 72 hours and mostly occurred in higher larval stage. Melanization was only recorded in encapsulated parasitoid inside larva body of C. pavonana, not in S. litura. We recorded that encapsulation increased blood cell number of both larvae C. pavonana and S. litura. Encapsulation may affect development of immature parasitoid. Weight of S. litura's pupae containing encapsulated parasitoid was found to be lower in S. litura, but not in C. pavonana. Our investigation also proved that superparasitism may help parasitoid avoid encapsulation.

Full grown male and female pupae of the Mediterranean flour moth, Ephestia kuehniella (Zell.) were exposed to gamma irradiation doses ranging from 40 to 450 Gy. Irradiated males were more radio-resistant than females. Reduction in fecundity and egg hatch were dose-dependant. Irradiated males or females showed significant shorter lifespan than control group. Also, there were reductions in F 1 progeny as a result of irradiating male and female parents with sub-sterilizing doses, which were more apparent in irradiating of male parents. The average larval pupal developmental period of F1 male and female progeny was affected. The sex ratio of F 1 generation was shifted in favor of males. The parental males or females irradiated as full-grown pupae were affected with sub-sterilizing dose of 200 Gy for male line and 100 Gy for female line. All possible mating combinations in F1, F 2 and F3 of males and females lines were examined. Fecundity and fertility of F I adults descendant from irradiated male parents were significantly reduced than F1 adults descendant from irradiated female parents. Also, the number of laid eggs and percentage of egg hatch were reduced drastically in crosses of F 1 males mated to unirradiated females of male line. Fecundity and fertility of the different mating combinations among F2 generation for both male and female treated lines were significantly decreased than the unirradiated control. Also, the number of adults resulting from all mating crosses among F2 generation was greatly reduced as compared to control adult progeny. There was a recovery in reproductive potential in moths of third generation for irradiated male line and in the second generation of the irradiated female line

Full Text Available Crocidolomia pavonana is an important pest of Brassicaceous vegetable crops. Botanical insecticides are potential alternatives for the control of C. pavonana pest. Insecticidal activity of Piper aduncum and Sapindus rarak fruit extracts as well as their mixtures was evaluated against C. pavonana larvae in the laboratory. Ethyl acetate P. aduncum (EtPa extract as well as methanolic S. rarak (MeSr and aqueous S. rarak (AqSr extracts were tested separately and in mixtures against second-instar larvae C. pavonana by a leaf-residue feeding method. At the LC95 level - 72 hours after treatment (HAT, EtPa extract was about 14.5 and 12.8 times, respectively, more toxic to C. pavonana larvae than MeSr and AqSr extracts. At the LC95 level, EtPa + MeSr extract mixture (1 : 10 w/w was about 1.64 times more toxic to the test larvae than EtPa + AqSr extract mixture (1 : 10 w/w. Based on combination index at 48, 72, and 96 HAT, EtPa + MeSr extract mixture at LC50 level as well as EtPa + AqSr extract mixture at LC50 and LC95 levels had additive joint action, whereas EtPa + MeSr extract mixture at LC95 was weakly synergistic. In addition to lethal effect, the treatment with all test materials delayed the development of C. pavonana larvae from second-instar to fourth instar. Thus, EtPa, MeSr, and AqSr extracts as well as the mixtures between EtPa and S. rarak extracts are potential alternatives for the control of C. pavonana pest.

We report on the population suppression of diamondback moth (DBM) Plutella xylostella (L.) (Lepidoptera: Plutellidae) and cabbage webworm (CWW) Crocidolomia binotalis Z. (Lepidoptera: Pyralidae) using releases of irradiated (200 Gy) substerile moths. The impact of substerile DBM was studied in field-cages and moths were released at a 9:1 treated:untreated ratio. Our results show that releasing F 1 substerile male and female DBM resulted in a high level of sterility (73.03% and 73.30% in the F 1 and F 2 generations, respectively) in the untreated population, while the release of only F 1 males induced a lower level of sterility (55.40% and 56.44% in the F 1 and F 2 generations, respectively). When substerile moths were released once per generation, the level of sterility was 44.78% in the F 1 and 68.01% in the F 2 generations. The effect of releasing substerile males only, females only, and substerile male and female CWW on the untreated population were studied in the laboratory. Percent egg hatch was 22.17% for male only releases. For female and mixed sex releases these percentages were 28.50% and 24.75%, respectively. For DBM, some studies combined releases of substerile DBM with releases of the parasitoid Diadegma semiclausum (H) (Hymenoptera: Ichneumonidae) in field-plots. Pupal viability in the F 1 generation in the area that received both parasitoids and substerile DBM was 32.5%. The effect on pupal viability when only a single tactic was used was lower than when both tactics were combined. The release of substerile males only gave a pupal viability of 57.5% and releases of the parasitoid D. semiclausum resulted in 81% pupal viability. When substerile DBM were released into a small isolated forested area in Malang, East Java, the average number of moths caught per week at the release area from June to October 1996 was about 89.42% of that found in the untreated control area. When population fluctuations of wild DBM were followed for 12 months, the lowest

A new measuring method for the destruction-free characterisation of impurities in basically large-surface [(20x20) mm{sup 2}]solar cells or photo detectors is explained. During this TPCR measuring method the transient photocurrent signal, generated by a repeating, rectangular, monochromatic irradiation, is recorded in dependence on the darkness between the irradiation pulses and on the temperature of the cells. (orig.) [Deutsch] Es wird ein neues Messverfahren zur zerstoerungsfreien Charakterisierung von Verunreinigungen in der Basis grossflaechiger [(20x20) mm{sup 2}] Solarzellen bzw. Photodetektoren vorgestellt. Bei diesem TPCR-Messverfahren wird das durch eine repetierende, rechteckfoermige, monochromatische Bestrahlung erzeugte transiente Photostrom-Signal in Abhaengigkeit von der Dunkelzeit zwischen den Bestrahlungspulsen und von der Tempeatur der Zelle aufgenommen.

Ahmed, M.Y.Y.; Abdel-Baky, S.M.; El-Bamby, M.A.; Salem, Y.S.

1985-01-01

The effects of gamma radiation on the pupal stage of Ephestia kuehniella (Zell.) was studied. Percent mortality of irradiated pupae increased gradually with increasing the dose. The dose 10 krad delivered to 1-2 day old pupae prevented adult emergence, while the dose 60 krad gave rise to 100% mortality of the full grown pupae. There was a gradual decrease in the percent of adult eclosion as a result of pupal irradiation at both ages. Life span of adults of both sexes, irradiated in the pupal stages, was shortened as the dose increased. The doses 25 and 45 krad induced complete sterility for females and males, respectively. Male pupae were more radioresistant than females. The fecundity and fertility were decreased by increasing the dose. The greater reduction in fecundity and fertility was obtained when both sexes were treated and mated together rather than when one sex only was treated. (author)

Larvae of Ephestia Kuehniella Z. were irradiated with different doses of gamma radiation to study the effect of irradiation on immature stages, pupation, emergence, malformation and sex ratio of the produced insects. Mortality percent of irradiated larvae was increased progressively with increasing the dose. Sublethal doses retarded the duration of the immature stages. There was a gradual decrease in adult eclosion and adult longevity with increasing the dose. Fecundity and fertility of the resulting adults were gradually reduced with the increase of the dose. No complete sterility occurred after larval irradiation. Malformed adults of both sexes increased as the dose was increased

Full Text Available The objective of this test was evaluate the insecticidal activity of ectract of some parts of Calophyllum soulattri (Clusiaceae against larvae of three species of Lepidoptera, i. e Crocidolomia pavonana, Plutella xylostela, and Pieris sp.. Extraction of plant materials was done by infusion method using ethanol. The bioassays were conducted by leaf-feeding method. Second-instar larvae were fed extract-treated broccoli leaves of 48 hours, then they were presented with untreated leaves until the surviving larvae larvae reached the fourth-instar stage. The number of dead larvae was recorded daily an larval mortality date were analyzed by probit method. The result showed the gummy bark exudates and bark extract of old and young C. soulattri plants were highly active against C. pavonana. The abrk extact of old C. soulattri plant was also effective against P. xilostella and Pieris sp. The gummy exudates possessed strong insecticidal activity against C. pavonana larvae with LC50 of 0.04% and prolonged the developmental time from second to fourth instar of C. soulattri 2.03-7.25 days compared with control. The bark excudate gave positive respon to alkaloid flavonoid, and tannin test. Futher studies are needed to identify insecticidal compound in those active extracts.

The project aimed at a better understanding of the complex fluid-mechanical processes in the small ducts of bipolar plates. So far, an appropriate technology for in-situ measurement was lacking. The project therefore focused on the further development of microparticle image velocimetry in order to enable analyses of the local velocity distribution of a gas stream in a microduct. Further, measurements were carried out in the microducts of a fuel cell in the more difficult conditions of actual operation. (orig./AKB) [German] Anlass des Forschungsvorhabens war die komplizierten stroemungsmechanischen Zusammenhaenge in den kleinen Kanaelen der Bipolarplatten zu verstehen. Bisher stand keine Messtechnik zur Verfuegung, dies es erlaubt, die stroemungsmechanischen Prozesse in den Mikrokanaelen unter Realbedingungen in situ zu vermessen und mit der instantanen Zellleistung zu korrelieren, Ziel des Projektes war es daher, die Methode der Mikro-Partikel-Image-Velocimetry in der Art weiterzuentwickeln, dass eine Analyse der lokalen Geschwindigkeitsverteilung einer Gasstroemung in einem Mikrokanal ermoeglicht wird. Darueber hinaus wird als zweites Ziel des Projekts eine solche Messung unter den erschwerten Bedingungen einer betriebenen Brennstoffzelle in Mikrokanaelen einer Zelle durchgefuehrt.

Evaluating gender similarities and differences using metasynthesis.

Zell, Ethan; Krizan, Zlatan; Teeter, Sabrina R

2015-01-01

Despite the common lay assumption that males and females are profoundly different, Hyde (2005) used data from 46 meta-analyses to demonstrate that males and females are highly similar. Nonetheless, the gender similarities hypothesis has remained controversial. Since Hyde's provocative report, there has been an explosion of meta-analytic interest in psychological gender differences. We utilized this enormous collection of 106 meta-analyses and 386 individual meta-analytic effects to reevaluate the gender similarities hypothesis. Furthermore, we employed a novel data-analytic approach called metasynthesis (Zell & Krizan, 2014) to estimate the average difference between males and females and to explore moderators of gender differences. The average, absolute difference between males and females across domains was relatively small (d = 0.21, SD = 0.14), with the majority of effects being either small (46%) or very small (39%). Magnitude of differences fluctuated somewhat as a function of the psychological domain (e.g., cognitive variables, social and personality variables, well-being), but remained largely constant across age, culture, and generations. These findings provide compelling support for the gender similarities hypothesis, but also underscore conditions under which gender differences are most pronounced.

Stable algorithms for magnetotomography of fuel cells; Stabile Algorithmen fuer die Magnetotomographie an Brennstoffzellen

Energy Technology Data Exchange (ETDEWEB)

Wannert, Martin

2010-07-01

For optimum fuel cell operation, the power distribution must be as homogeneous as possible. It is therefore important for research, diagnosis and maintenance to be able to measure the power distribution inside a fuel cell. The book presents a non-invasive measuring method that reconstructs the internal power distribution from the magnetic field outside the fuel cell. Reconstruction algorithms are developed and tested for stability. The algorithms comprise a certain prior knowledge of the real power distribution; on the other hand, the magnetic field is split up numerically into different part-fields in order to reduce the complexity of the problem. [German] Um einen optimalen Brennstoffzellenbetrieb zu gewaehrleisten, ist es notwendig, eine moeglichst homogene Stromverteilung sicher zu stellen. Daher ist es aus Forschungs-, Diagnose- und Wartungszwecken von Interesse, die Stromverteilung in einer Zelle messen zu koennen. In diesem Buch wird ein nicht-invasives Messverfahren vorgestellt, das aus dem Magnetfeld ausserhalb der Brennstoffzelle die innere Stromverteilung rekonstruiert. Dabei werden Rekonstruktionsalgorithmen entwickelt und auf ihre Stabilitaet hin analysiert. Die Algorithmen beinhalten zum einen ein gewisses Vorwissen ueber die wahre Stromverteilung, zum anderen wird zuerst das Magnetfeld numerisch in unterschiedliche Teilfelder aufgespaltet, um so die Komplexitaet des Problems zu reduzieren.

This study examined juvenile justice-involved youths' understanding and appreciation of the Miranda warnings' rights to silence and legal counsel using the Miranda Rights Comprehension Instruments (Goldstein, Zelle, & Grisso, 2012). It also examined the relationships between totality of circumstances factors and understanding and appreciation of rights. Data were collected from 183 youths (140 boys) in pre- and postadjudication facilities in 2 states. Overall, youths demonstrated greater difficulty on measures of appreciation than understanding, with particular deficits in their abilities to comprehend the abstract concept of the right to silence. Results varied slightly by instrument, highlighting the importance of a multimodal assessment of these complex abilities. Examination of totality of circumstances factors identified relationships between some factors (e.g., age, verbal IQ, academic achievement) and Miranda comprehension, but revealed that other factors (e.g., gender, number of previous arrests) were not significantly related to Miranda understanding or appreciation. The findings support a nuanced conceptualization of Miranda rights comprehension that acknowledges the complexity of understanding and appreciating the warnings. Empirical analyses also support the continued use of some totality of circumstances factors and abandonment of others. Findings underscore the necessity of multimodal assessment and interpretation when conducting capacity to waive Miranda rights evaluations. (c) 2015 APA, all rights reserved).

In the future sensors will be necessary to control the compliance with hydrocarbon limiting values, allowing a direct detection of the hydrocarbons. Appropriate sensor-active functional materials are metal oxides, which have a hydrocarbon sensitivity but are also dependent on the oxygen partial pressure. It is proposed that the gas-sensing layer should be integrated into an electrochemical cell. The authors show that the integration of a resistive oxygen sensor into a pump cell allows a defined oxygen concentration level at the sensor layer in any exhaust gas.

Disinfestation of different varieties of potato naturally or artificially infested by the potato tuber moth, Phthorimea Operculella Zell. In the storage

International Nuclear Information System (INIS)

Haiba, M.I.

1994-01-01

The exposure of potato tuber varieties of Alpha, Spunta, Cara and escort to radiation dose level of 150 Gy could be used to disinfest the potatoes from their natural attacked pest, Phthorimaea Operculella, after the harvest and before storage. Escort variety exhibited somewhat resistance to the natural infestation if compared with the others. The irradiation of the potato tubers did not protect them from the re infestation, during the storage. Also, there were significant changes in some biological properties of the resulted pests, among the four potato varieties, whether the potatoes were non-irradiated or irradiated. The feeding of the artificial infested larvae on the treated tubers gave some malformed adults. 3 tabs

VPython: Python plus Animations in Stereo 3D

Science.gov (United States)

Sherwood, Bruce

2004-03-01

Python is a modern object-oriented programming language. VPython (http://vpython.org) is a combination of Python (http://python.org), the Numeric module from LLNL (http://www.pfdubois.com/numpy), and the Visual module created by David Scherer, all of which have been under continuous development as open source projects. VPython makes it easy to write programs that generate real-time, navigable 3D animations. The Visual module includes a set of 3D objects (sphere, cylinder, arrow, etc.), tools for creating other shapes, and support for vector algebra. The 3D renderer runs in a parallel thread, and animations are produced as a side effect of computations, freeing the programmer to concentrate on the physics. Applications include educational and research visualization. In the Fall of 2003 Hugh Fisher at the Australian National University, John Zelle at Wartburg College, and I contributed to a new stereo capability of VPython. By adding a single statement to an existing VPython program, animations can be viewed in true stereo 3D.

Full Text Available The Municipality of Tržič borders with the Republic of Austria at the main ridge of the Karavanke mountain. Cooperation with the neighbouring communities Borovlje/Ferlach and Sele/Zell Pfare started in the eighties and it has become more intense after the year 1991. The border that was once separating the inhabitants on both sides of the mountain ridge has become more opened after the slovenian independence but the border control is after Schengen agreement more severe. Remote mountain border areas where access used to be limited were suddenly recognised as a great touristic potential. In the recent years the Municipality of Tržič together with Austrian partners managed to form some joined agriculture and tourism development projects within the PHARE programme (CBC - Crossborder Cooperation and ECOS - Ouverture. The projects deal with the regrowing of buckwheat, preservation of a special sheep breed - jezersko solčavska sheep, activation of the natural monument Dovžan gorge which will be logistically connected to Tscheppa gorge on the austrian side. Within the ECOS Ouverture programme the project of Thematic trails around the Košuta mountain has been initiated in order to reactivate and connect hidden natural and cultural potentials into integrated touristic offer of this part of the Karavanke mountain.

Repetitive DNA sequences of the LINE-family (long interspersed elements) that are widely distributed among the mammalian genome can be activated or altered by the exposure to ionizing radiation [1]. By the integration at new sites in the genome alterations in the expression of genes that are involved in cell transformation and/or carcinogenesis may occur [2, 3]. A new technique - the inter-LINE PCR - has been developed in order to detect and analyse such genomic rearrangements in radiation-transformed cell lines. From the sites of transformation- or tumour-specific changes in the genome it might be possible to develop new tumour markers for diagnostic purpose. (orig.) [Deutsch] Repetitive DNA-Sequenzen der LINE-Familie, die weit verbreitet im Genom von Saeugerzellen vorkommen, koennen durch Exposition mit ionisierender Strahlung aktiviert und veraendert werden [1]. Durch eine Neu- bzw. Reintegration an anderen Positionen im Genom kann es zu bedeutenden Veraenderungen im Genom der Zelle kommen. Die Expression von Genen, die bei den Prozessen der Zelltransformation bzw. der Karzinogenese beteiligt sind, kann dadurch veraendert werden [2, 3]. Mithilfe der von uns entwickelten Inter-LINE PCR und der anschliessenden Analyse der veraenderten Produktmuster nach gelelektrophoretischer Auftrennung koennen solche `genomic rearrangements` unter Beteiligung von LINE-Elementen untersucht und naeher charakterisiert werden. Durch Klonierung und Sequenzierung transformations- bzw. tumorspezifischer PCR-Produkte sollte es moeglich sein Tumormarker fuer diagnostische Zwecke zu entwickeln. Die Methode wurde fuer die Analyse von Zellen des Syrischen Hamster aufgebaut, sie ist jedoch universell fuer alle Saeuger anwendbar. (orig.)

A novel application of a commonly used statistical approach was used to examine differences in polychlorinated biphenyl (PCB) congener patterns among locations and sample matrices in tree swallows (Tachycineta bicolor) nesting in the Housatonic River watershed in western Massachusetts, USA. The most prevalent PCB congeners in tree swallow tissue samples from the Housatonic River watershed were Ballsmitter Zell numbers 153, 138, 180, 187, 149, 101, and 170. These congeners were seven of the eight most prevalent congeners in Aroclor[reg] 1260, the PCB mixture that was the primary source of contamination in the Housatonic River system. Using paired-Euclidean distances and tolerance limits, it was demonstrated that congener patterns in swallow tissues from sites on the main stem of the Housatonic River were more similar to one another than to two sites upstream of the contamination or from a nearby reference area. The congener patterns also differed between the reference area and the two upstream tributaries and between the two tributaries. These pattern differences were the same in both pipper (eggs or just hatched nestlings) and 12-day-old nestling samples. Lower-chlorinated congeners appeared to be metabolized in nestlings and pippers compared to diet, and metabolized more in pippers compared to nestlings. Euclidean distances and tolerance limits provide a simple and statistically valid method to compare PCB congener patterns among groups. - Polychlorinated biphenyl congener patterns in swallows differed between the main stem of the Housatonic River, MA and other locations in the watershed

Biosorption of heavy metals by immobilized microalgae; Biosorption von Schwermetallen durch immobilisierte Mikroalgen

Some microalgae stand out by the fact that they are highly capable of adsorbing heavy metals (biosorption). In contrast to bioaccumulation, where heavy metals are actively integrated into living cells, biosorption is a process of chemical-physical deposition to functional groups of the cell wall components. For a process-technological application, different reactor configurations may be used. Owing to different advantages such as a continuous mode of operation, attainable low effluent concentrations, low operating cost, ease of scaling up, modular design, modest space demand and a high degree of automation, packed-bed adsorption is the process-technological solution to be preferred. Mathematical modelling of adsorption kinetics as a basis for scaling up requires knowledge of resistances to suspended matter transport for the adsorbents used. By appropriate experiments the different resistances (film resistance, diffusion resistance inside particles) need to be decoupled from each other prior to their determination. (orig.) [German] Einige Mikroalgen zeichnen sich dadurch aus, im hohen Masse Schwermetalle zu adsorbieren (Biosorption). Im Gegensatz zur Bioakkumulation, bei der die Schwermetalle aktiv in die lebende Zelle aufgenommen werden, handelt es sich bei der Biosorption um einen chemischen/physikalischen Anlagerungsprozess an funktionelle Gruppen der Zellwandkomponenten. Fuer eine verfahrenstechnische Umsetzung koennen unterschiedliche Reaktorkonfigurationen verwendet werden. Aufgrund verschiedener Vorteile wie kontinuierliche Betriebsweise, niedrige erreichbare Ablaufkonzentration, geringe Betriebskosten, einfache Scale-up-Faehigkeit, modulare Bauweise, geringer Platzbedarf sowie hoher Automatisierungsgrad ist eine Festbettadsorption als verfahrenstechnische Loesung vorzuziehen. Eine mathematische Modellierung der Adsorptionskinetik, als Basis einer Massstabsvergroesserung, erfordert die Kenntnis der Stofftransportwiderstaende bei den verwendeten Adsorbentien

Deren größter Risikofaktor ist „das Altern“ selbst.brIn Tiermodellen können durch bestimmte Substanzen und Lebensführung die gesunde Lebensspanne verlängert und das Altern verzögert werden. Dies wird durch physiologische Signalketten vermittelt, die evolutionär konserviert erscheinen. Im Mittelpunkt solcher Regulatoren steht der mTOR-Komplex („mechanistic Target of Rapamycin“. Er verknüpft Signale wie Energie-, Nahrungs- und Stressstatus mit grundlegenden Aktivitäten der Zelle, zu denen Proliferation versus Zellarrest sowie Reparatur versus Apoptose gehören.brDie Zellregulation auf solche Signale bzw. Stressoren erfolgt nicht linear, sondern biphasisch (U-förmig, glockenförmig als hormetisches Prinzip.

In consequence of the European guidelines of safety and quality standards for the donation, retrieval, storing and distribution of human tissues and cells the purpose of tissue transplantation was implemented into German legislation in May 2007. The law came into effect on August 1st 2007 considering of the European rules. The Institutes for Legal Medicine of the University of Frankfurt/Main and the University Medical Center Hamburg-Eppendorf developed a model for tissue retrieval. The Institute of Legal Medicine (I.f.R.) at the University Medical Center Hamburg cooperates with the German Institute of Cell and Tissue Replacement (Deutsches Institut für Zell--und Gewebeersatz DIZG). Potential post-mortem tissue donors (PMTD) among the deceased are selected by standardized sets of defined criteria. The procedure is guided by the intended exclusion criteria of the tissue regulation draft (German Transplant Law TPG GewV) in accordance with the European Guideline (2006/17/EC). Following the identification of the donor and subsequent removal of tissue, the retrieved samples were sent to the DIZG, a non-profit tissue bank according to the tissue regulation. Here the final processing into transplantable tissue grafts takes place, which then results in the allocation of tissue to hospitals in Germany and other European countries. The Center of Legal Medicine at the Johann Wolfgang Goethe-University Medical Center Frankfurt/Main cooperates since 2000 with Tutogen, a pharmaceutical company. Harvesting of musculoskeletal tissues follows corresponding regulations. To verify the outcome of PMTD at the I.f.R. Hamburg, two-statistic analysis over 12 and 4 months have been implemented. Our results have shown an increasing number of potential appropriate PMTD within the second inquiry interval but a relatively small and unvaryingly rate of successful post-mortem tissue retrievals similar to the first examination period. Thus, the aim of the model developed by the I.f.R. is to

Quarternary sediments in overdeepened alpine valleys and basins in the Eastern Alps bear substantial groundwater resources. The associated aquifer systems are generally geometrically complex with highly variable hydraulic properties. 3D geological models provide predictions of both geometry and properties of the subsurface required for subsequent modelling of groundwater flow and transport. In hydrology, geostatistical Kriging and Kriging based conditional simulations are widely used to predict the spatial distribution of hydrofacies. In the course of investigating the shallow aquifer structures in the Zell basin in the Upper Salzach valley (Salzburg, Austria), a benchmark of available geostatistical modelling and simulation methods was performed: traditional variogram based geostatistical methods, i.e. Indicator Kriging, Sequential Indicator Simulation and Sequential Indicator Co - Simulation were used as well as Multiple Point Statistics. The ~ 6 km2 investigation area is sampled by 56 drillings with depths of 5 to 50 m; in addition, there are 2 geophysical sections with lengths of 2 km and depths of 50 m. Due to clustered drilling sites, indicator Kriging models failed to consistently model the spatial variability of hydrofacies. Using classical variogram based geostatistical simulation (SIS), equally probable realizations were generated with differences among the realizations providing an uncertainty measure. The yielded models are unstructured from a geological point - they do not portray the shapes and lateral extensions of associated sedimentary units. Since variograms consider only two - point spatial correlations, they are unable to capture the spatial variability of complex geological structures. The Multiple Point Statistics approach overcomes these limitations of two point statistics as it uses a Training image instead of variograms. The 3D Training Image can be seen as a reference facies model where geological knowledge about depositional

Apart from the high acquisition cost, the major obstacles to widespread use of electric-powered vehicles today are long battery charging times and limited mileage. Rechargeable batteries might be a solution. The publication investigates a potential infrastructure for electric-powered vehicles based on so-called redox flow batteries. Redox flow batteries are characterized in that active materials are dissolved in liquid electrolyte and are stored outside the cell. Batteries are recharged by exchanging charged electrolyte for discharged electrolyte, which can be done in fuel stations. Redox flow batteries have the drawback of low energy and power density and were hardly ever considered for mobile applications so far. A technical analysis of RFB technology identified the vanadium oxygen redox flow fuel cell (VOFC) as a promising version. It provides higher energy density than conventional redox flow batteries, but development is still in an early stage. Assuming a 'best case' scenario, a refuelling infrastructure for VOFC vehicles was developed and compared with battery-powered vehicles (BEV) and fuel cell vehicles (FVEV). It was found that electromobility based on VOFC may be a promising alternative to current electromobility concepts.

Full Text Available Ekonomi ve eğitim ilişkisi birçok araştırmaya konu olmuş ve eğitim süreçlerinin ekonomik politikalara hizmet etmesi kabul edilen bir olgudur. Kapital sistemin oluşturduğu eşitsiz yarış sisteminin yeniden oluşturucusu yine eğitim süreçleri olarak düşünülmektedir. Eğitimin dünya genelinde belirli bir standarda ulaşıp, birçok ülkede benzer politikalar ile pazar ekonomisine hizmet edecek yapıya kavuşturulması neoliberal politikaların bir amacı olduğu düşünülmektedir. Ülkeler arasında benzer eğitim politikaları oluşturmanın etkili bir yolu günümüzde yapılan uluslararası sınavlardır. TIMSS, PISA ve PIRLS gibi sınavlar ülkelerin eğitim karnelerini ve ilişkili birçok değişkeni ülkelerin gündemine getirerek reform yapma gereksinimi algısı oluşturmaktadır. Bu reform algısının temel hedefinde ise dünya pazarında daha rekabetçi bir ekonomi için daha yarışçı bir eğitim anlayışıdır. Eğitimin insani gelişimden ziyade ekonomiye hizmet edecek donanımlı bireyler yetiştirmeye odaklanması sonucunda eşitsizlik sosyo-ekonomik duruma göre daha da derinleşmektedir. Her ne kadar uluslararası sınavların raporlarında eğitim eşitsizliğin giderilip öğrenciler arasındaki farkın kapatılması yönünde tavsiyeler barındırsa bile ülkelerin eğitim reformlarında özelleştirmeye gitmeleri ve değişimi takip eden öğretmen kalitesinin farklılık göstermesi nedeniyle öğrenci başarısındaki açı daha da büyümektedir. Bu araştırmanın amacı da bu sorunları literatür çerçevesinde işlemektir. Böylece hızlı reformların olduğu ülkemizde değişim adımlarının daha hesaplı atılmasında katkı sağlanması umulmaktadır.

Effects of gamma radiation on the melanization process in larvae of stored product moths

1998-01-01

Non-irradiated larvae of the Indian meal moth (Plodia interpunctella Hbn.), the Mediterranean flour moth (Ephestia (Anagasta) kuehniella Zell.), and the almond moth (Cadra cautella Wlk.) showed strong melanization after killing by freezing. However, there were some insects which showed lack of melanization or melanized only partly, sometimes like those that have been irradiated. A part of the larval body was dark black while the rest body was of natural color or only slightly gray. Also, black and gray patches were observed in the larvae. After the irradiation treatment, the number of non-melanized larvae and larvae exhibiting a slight melanization usually increased. The degree of melanization in the treated larvae was significantly different from the untreated insects. Generally, it decreased with increasing dose and time elapsed after the treatment. The melanization test for detecting irradiated moth larvae may produce inconsistent results because (a) irradiation does not completely prevent melanization in mature moth larvae, and (b) the untreated larvae, killed by freezing and examined at room temperature, often show incomplete melanization. An ideal method for detection of irradiated insects should be: (1 ) specific for irradiation and not influenced by other processes, (2) accurate and reproducible, (3) have a detection limit below the minimum dose likely to be applied to agricultural commodity as a quarantine treatment, (4) applicable to a range of pests, (5) quick and easy to perform, and (6) capable of providing an estimate of irradiation dose. The melanization test to detect irradiated larvae of the stored product moths fulfills only some of these requirements. Therefore, additional studies were performed to improve this test before it is recommended for quarantine inspection. Because visual assessment of the effects of irradiation on melanization of the moth larvae is very subjective and difficult to perform, a trial to determine the activity of

Using microwaves in Disinsection of dates

The date palm plays a very significant role in Tunisia in term of culture as well as social, economic and ecological aspects. The production of the dates which is estimated to 120.000 tons/year ensures the principal income for the majority of the oasis population of the South of Tunisia and constitutes the basis for agricultural, industrial, commercial and tourist activities, offering million of working days. The date palm is cultivated mainly for the production of dates which are consumed locally or also exported abroad but for its by-products (food of the cattle, wind breaks, fuel, construction) which are marketed and/ or used in the everyday life thus taking part in the sedentarisation of the populations and the maintenance of a fragile socio-economic balance. The date moth, Ectomyelois ceratoniae Zell. ( L will epidoptera, Pyralidae) is without question the most significant problem of the Tunisian date palm. The infestation of dates in the field and in the storage and packing houses enormously depreciates the marketable quality of dates and risk to compromise exports in particular those of the variety Deglet Nour. rates of infestations of about 20% are often recorded in Tunisia where as the European standards require rates lower than 5%. In Tunisia the desinsectisation of dates is done until now by the use of methyl bromide, its high toxicity substantially reduces the duration of date treatment, and consequently the treated volumes. The replacement of this product becomes an urgent need its use will not be authorized by 2015. Within the framework of a agreement between the Regional Research Center in Oasis Agriculture (CRRAO), The Interprofessional Grouping of Fruits (GIF), and the Italian Company IMETEC, the use one of micro-waves as a desinsectisation method of dates was evaluated. The results of this present work showed that total desinsectisation of dates by microwaves can be obtained only with homogeneous dates in term of water content. Total

Low-dose total skin electron beam therapy (TSEBT) is attracting increased interest for the effective palliative treatment of primary cutaneous T-cell lymphoma (pCTCL). In this study, we compared toxicity profiles following various radiation doses. We reviewed the records of 60 patients who underwent TSEBT for pCTCL between 2000 and 2016 at the University Hospital of Munster. The treatment characteristics of the radiotherapy (RT) regimens and adverse events (AEs) were then analyzed and compared. In total, 67 courses of TSEBT were administered to 60 patients. Of these patients, 34 (51%) received a standard dose with a median surface dose of 30 Gy and 33 patients (49%) received a low dose with the median surface dose of 12 Gy (7 salvage low-dose TSEBT courses were administered to 5 patients). After a median follow-up of 15 months, the overall AE rate was 100%, including 38 patients (57%) with grade 2 and 7 (10%) with grade 3 AEs. Patients treated with low-dose TSEBT had significantly fewer grade 2 AEs than those with conventional dose regimens (33 vs. 79%, P < 0.001). A lower grade 3 AE rate was also observed in patients who had received the low-dose regimen compared to those with the conventional dose regimens (6 vs. 15%, P = 0.78). Multiple/salvage low-dose TSEBT courses were not associated with an increased risk of acute AEs. Low-dose TSEBT regimens are associated with significantly fewer grade 2 acute toxicities compared with conventional doses of TSEBT. Repeated/Salvage low-dose TSEBT, however, appears to be tolerable and can even be applied safely in patients with cutaneous relapses. (orig.)

of permafrost temperatures in western Austria. A central recommendation of the permAT-strategy is to increase the number of monitoring sites based on our analyses of the current situation and exchanges with different stakeholders. This should include temperature measurements in deep and shallow boreholes close to the surface, geophysical surveys and ground movement measurements (rock glaciers, instable rock faces). In addition to the terrestrial measurements a spatially continuous observation of surface movements with remote sensing methods is required. Demand is highest for the entire federal province of Tyrol, the district of Zell am See (province of Salzburg) and the south-eastern part of the province of Vorarlberg. In order to achieve a similar spatial coverage and technical set-up as in Switzerland a minimum investment of 1.5 Mio € is required taking advantages in synergies with e.g. existing automatic weather stations (e.g. from the Central Institute for Meteorology and Geodynamics), alpine huts and skiing infrastructure into account. Financial support could - similarly to Switzerland - come from a combination of partners from public institutions, economy and research institutes.

Kapillarelektrophorese zurückgegriffen. Eine Methode, die mit sehr kleinen Probenvolumina auskommt, eine hohe Trennung erzielt und zudem extrem geringe Detektionslimits besitzt. Die Analyse von Kohlenhydraten und Anionen erfordert eine weitere Optimierung. Über UV-Detektion konnte die K+-Konzentration in verschiedenen Geweben von A. thaliana bestimmt werden. Sie lag in Epidermis und Mesophyll mit ca. 25 mM unterhalb der für andere Pflanzenspezies (Solanum tuberosum und Hordeum vulgare) publizierten Konzentration. Weiter konnte gezeigt werden, daß zwölf freie Aminosäuren mittels einer auf Kapillarelektrophorese basierenden Methode in vereinigten Zellproben von Cucurbita maxima identifiziert werden konnten. Die Übertragung der Methode auf A. thaliana-Proben muß jedoch weiter optimiert werden, da die Sensitivität selbst bei Laser induzierter Fluoreszenz-Detektion nicht ausreichte. Im dritten und letzten Teil der Arbeit wurde eine Methode entwickelt, die die Analyse bekannter wie unbekannter Proteine in Gewebe-spezifischen Proben ermöglicht. Hierzu wurde zur Probennahme mittels mechanischer Mikrodissektion eine alternative Methode zur Laser Capture Microdissection verwendet, um aus eingebetteten Gewebeschnitten distinkte Bereiche herauszuschneiden und somit homogenes Gewebe anzureichern. Aus diesem konnten die Proteine extrahiert und über Polyacrylamidgelelektrophorese separariert werden. Banden konnten ausgeschnitten, tryptisch verdaut und massenspektrometrisch die Primärsequenz der Peptidfragmente bestimmt werden. So konnten als Hauptproteine im Mesophyll die große Untereinheit von Rubisco sowie ein Chlorophyll bindendes Protein gefunden werden. Die in dieser Arbeit entwickelten und auf die Modellpflanze Arabidopsis thaliana angewandten Einzelzellanalysetechniken erlauben es in Zukunft, physiologische Prozesse besser sowohl räumlich als auch zeitlich aufzulösen. Dies wird zu einem detaillierteren Verständnis mannigfaltiger Vorgänge wie Zell-Zell

no marginal failures occurred. The concept of IS will likely reduce the risk for late sequelae of RT. (orig.) [German] Die konsolidierende Radiotherapie (RT) in Kombination mit einer Chemoimmuntherapie stellt eine hocheffiziente Therapiemethode in der Behandlung des diffusen grosszelligen B-Zell-Lymphoms (DLBCL) dar. Die vorliegende retrospektive Analyse evaluiert die Effektivitaet und Sicherheit des Volumen- und Dosiskonzepts der ''Involved-site''-Radiotherapie (ISRT). Wir identifizierten 60 Patienten mit histologisch gesichertem DLBCL im Stadium I-IV, die zwischen Januar 2005 und Dezember 2015 mit einer Chemoimmuntherapie und konsolidierender ISRT behandelt wurden. Progressionsfreies (PFS) und Gesamtueberleben (OS) wurden mittels Kaplan-Meier-Methode dargestellt und univariate Analysen mittels Log-rank-Test und Mann-Whitney-U-Test erhoben. Nach einer initialen Chemoimmuntherapie (ueberwiegend R-CHOP; Rituximab, Cyclophosphamid, Doxorubicin, Vincristin und Prednisolon) erzielten 19 Patienten (36 %) eine komplette (CR) und 34 (64 %) eine partielle Remission (PR) oder weniger. Ausgeschlossen wurden 7 Patienten (12 %) mit einem Progress nach Chemoimmuntherapie. Alle Patienten erhielten eine ISRT mit 40 Gy Gesamtdosis. Nach einer medianen Nachbeobachtungszeit von 44 Monaten waren 79 % der Patienten erkrankungsfrei, waehrend 21 % ein Rezidiv oder einen systemischen Progress erlitten oder verstarben. Alle Patienten mit CR nach Chemoimmuntherapie blieben nach konsolidierender ISRT in CR. Bei 2 Patienten mit PR nach Chemoimmuntherapie trat ein Rezidiv an Stelle der initialen Laesion innerhalb des IS-Planungszielvolumens (PTV) auf. Feldrandrezidive wurden nicht beobachtet. Ein signifikant verbessertes PFS zeigten ein Ann-Arbor-Stadium I/II im Vergleich zu Stadium III/IV (93 % vs. 65 %; p ≤ 0,021) sowie ein internationaler prognostischer Index (IPI) von 0 oder 1 verglichen mit 2-5 (100 % vs. 70 %; p ≤ 0,031).

- and p-type emitters have been fabricated. After a very short development time conversion efficiencies have been obtained ({eta}{sub max} = 15.2%) which are reported for PECVD emitters. (orig.) [German] Zwei neue Anlagen zur vollstaendigen bzw. grossflaechigen Abscheidung von a-Si:H basierenden Solarzellen mit der sog. 'Hot-Wire (HW)' CVD wurden aufgebaut. Die Abscheidebedingungen fuer geeignete n- und p-dotierte a-Si:H- bzw. {mu}c-Si:H-Schichten wurden ermittelt. Weltweit wurde erstmals eine a-Si:H-pin-Zelle vollstaendig mit der HWCVD-Methode hergestellt, ein Anfangswirkungsgrad von {eta}{sub initial} = 8,9% wurde erreicht. Nach Entwicklung eines p/n-Tunnel- bzw. Rekombinationsueberganges ist es weltweit ebenfalls erstmals gelungen, pin-pin-Tandemstrukturen mit a-Si:H-Absorbern vollstaendig mit der HWCVD-Methode abzuscheiden. Nach Teilalterung wurden noch Wirkungsgrade von {eta}{approx}7% ermittelt. Generell ist die Stabilitaet der all-HWCVD-Zellen noch unbedriedigend, was auf strukturell instabile p-Schichten zurueckgefuehrt werden konnte. Erste nip-Solarzellen auf Edelstahlsubstraten wurden ebenfalls vollstaendig mit der HWCVD praepariert ({eta}{sub initial}>6%). Der Einbau von {mu}c-Si:H-Absorberschichten die mit HWCVD bzw. ECWR-PECVD hergestellt wurden, in pin-Solarzellen war bisher wenig erfolgreich. In einer Anlage zur grossflaechigen HWCVD-Abscheidung wurden a-Si:H-Schichten mit guter Qualitaet und einer Schichtdickenuniformitaet von {delta}d = {+-}2,5% hergestellt. Fuer sog. 'Huepfzellen', nur die i-Schicht wurde in der Anlage abgeschieden, wurden auch sehr uniforme Anfangswirkungsgrade {eta}{sub initial}=6,1{+-}0,2% fuer kleinflaechige Zellen auf einer Flaeche von 20 x 20 cm{sup 2} erreicht. Diese Ergebnisse koennen als 'proof of concept' fuer die grossflaechige HWCVD-Abscheidung fuer a-Si:H-basierende Solarzellen betrachtet werden. Erstmals wurde die HWCVD zur Abscheidung von Emitter-Schichten fuer Hetero-Solarzellen auf c

Full Text Available Introduction: The common pistachio psylla (CPP, Agonoscena pistaciae Burckhardt and Lauterer, 1989 (Hem.: Psylloidea: Rhinocolinae is an important pest of pistachio trees. The presence of a large population of psyllid causes severe problems such as falling buds and leaves and therefore this pest causes heavy economic damage to farmers. Predators are the largest and the most diverse natural enemies of the CPP. They are offered as biological control agents against pistachio pests, especially CPP, although they are mostly general predators. Oenopia conglobata contaminata (Menteries is one of the common psylla predators of pistachio orchard that have a significant role in biological control of Agonoscena pistaciae population. Despite the importance of this efficient predator, the limited study has been done on the effect of different hosts on the biological parameters of this lady beetle. In this study, the demographic parameters of this lady beetle by feeding on 4 different prey species, A. pistaciae , Aphis fabae Scopoli (Hem.:Aphididae, Aphis gossypii Glover (Hem.:Aphididae and eggs of Ephestia kuehniella (Zell.(Lep.:Pyralidae were studied in the laboratory conditions (25 ± 2°C, relative humidity of %65 ±5 and photoperiod of 16 hours light and 8 hours of darkness. Materials and Methods: Nymphs of CPP (A.pistaciae and adults of O. conglobata contaminata beetles were collected on the pistachio leaves from a pistachio orchard. Aphids (A. fabae and A. gossypii were reared on the bean and the cotton plants planted in a greenhouse. Eggs of E. kuehniella were prepared from insectarium of Kerman Plant protection management and rearing of E. kuehniella was done in the laboratory conditions in Kerman Agricultural and Natural Resoarce Research Center. Before starting the experiment, one generation of O. conglobata contaminata was reared in the laboratory on the different host separately. One hundred eggs of O. conglobata contaminata were used to

şehir temiz hava planı (2011-2014 hazırlanmıştır. Partikül Madde ve SO2 yanında NO2,O3 ve PAH gibi kirleticilerin ve ulaşım araçlarının neden olduğu kirliliğin de irdelendiği bu raporda, Eskişehir için ulusal yasal sınır değerleri zorlayan bir durum söz konusu olmasa da geniş ölçekte Avrupa Birliği ve Dünya Sağlık Örgütü (DSÖ gibi kuruluşların oluşturmuş olduğu standartların üzerinde değerlere rastlandığı kaydedilmektedir. Hava kirliliğinin önlenmesi amacıyla doğal gaz kullanımına ilk kez Eskişehir Organize Sanayi Bölgesinde (EOSB Botaş bünyesinde 1990 yılında başlanılmış daha sonra bu hizmet özelleştirme kapsamı içerisinde 2004 yılında Eskişehir Doğal Gaz Dağıtım A.Ş. (ESGAZ firmasına devredilmiştir. ESGAZ, Büyükşehir Belediyesi mücavir alanlarda yer alan imara açık tüm cadde ve sokaklara doğal gaz hizmeti vermekte olup 2004 yılında devir alınan 107.000 bağımsız birim sayısını 2011 yılı sonu itibariyle 300.000’e çıkartmıştır. EOSB bölgesi hariç evsel ve şehir içi sanayi tüketimi de 2005 yılında 211.756.888 m3 iken, 2011 yılında 348.974.147 m3’e çıkmıştır. Tüm bu olumlu gelişmelere karşın doğal gaz alt yapısı bulunan bazı semt ve apartmanlarda günümüzde de ithal ve yerli kömür kullanılması zaman zaman hava kirliliğine neden olmaktadır. İlk aşamada kent merkezinde özellikle kış aylarında kömür yerine tamamen doğal gaza geçilmesi ve ulaşım kaynaklı hava kirliğinin azaltılması için gereken önlemlerin alınması önerilmiştir. History of Air Pollution and Natural Gas Usage in Eskişehir: A General Review The aim of this study is to investigate the use of natural gas and air pollution levels in Eskişehir City Center in the last 30 years. Air pollution has been phenomena in Eskişehir since the beginning of 1980s, due to the use of low quality coal, unplanned and irregular urbanization and negative climate factors. First air
