  7. Population trends of Goričko agricultural landscape birds

    2017-12-01

    Full Text Available Due to numerous bird surveys in the past 20 years, the avifauna of Goričko is relatively well known. For some species, the very first national ecological researches were conducted in this area. The article summarizes all bird surveys so far. It presents population trends of farmland species which is one of the most threatened bird groups in Europe. Most of the qualifying species of this habitat that are protected within the Natura 2000 network have suffered a decline at Goričko, specifically Quail Coturnix coturnix, Scops Owl Otus scops, Hoopoe Upupa epops, Woodlark Lullula arborea and White Stork Ciconia ciconia. The number of breeding pairs of the latter has not changed, but its fecundity has decreased. Furthermore, populations of other farmland bird species have decreased, for example Skylark Alauda arvensis, Stonechat Saxicola rubicola, Serin Serinus serinus and Common Linnet Linaria cannabina, as well as butterfly populations and tracts of grassland habitat types. National agricultural and nature conservation policies are evidently inefficient in protecting the biodiversity of Goričko. The most probable cause for bird population decline is agricultural intensification, which manifests itself at Goričko as disappearance and intensification of meadows, land consolidation, degradation of traditional orchards and use of pesticides. As a result of land consolidation hedges, uncultivated strips between fields, individual trees and bushes and minority habitat types are disappearing, whereas the surface of arable fields is increasing. Nature conservation measures performed by the Public Institute Goričko Nature Park with the support of DOPPS – BirdLife Slovenia volunteers seem to be efficient, but are spatially and temporally constrained. For this reason, they cannot serve as a substitute for insufficient systemic financing which could be improved by substantive and financial reform of the agri-environmental scheme. Currently, a negligible

    The virulence of chlamydial infection in wild koalas is highly variable between individuals. Some koalas can be infected (PCR positive) with Chlamydia for long periods but remain asymptomatic, whereas others develop clinical disease. Chlamydia in the koala has traditionally been studied without regard to coinfection with other pathogens, although koalas are usually subject to infection with koala retrovirus (KoRV). Retroviruses can be immunosuppressive, and there is evidence of an immunosuppressive effect of KoRV in vitro. Originally thought to be a single endogenous strain, a new, potentially more virulent exogenous variant (KoRV-B) was recently reported. We hypothesized that KoRV-B might significantly alter chlamydial disease outcomes in koalas, presumably via immunosuppression. By studying sub-groups of Chlamydia and KoRV infected koalas in the wild, we found that neither total KoRV load (either viraemia or proviral copies per genome), nor chlamydial infection level or strain type, was significantly associated with chlamydial disease risk. However, PCR positivity with KoRV-B was significantly associated with chlamydial disease in koalas (p = 0.02961). This represents an example of a recently evolved virus variant that may be predisposing its host (the koala) to overt clinical disease when co-infected with an otherwise asymptomatic bacterial pathogen (Chlamydia).

    Meteorite fall was observed by the Košice town in Slovakia in February 2010 and it was classified as an ordinary chondrite H5. The samples were prepared in powder form scratched from the surface. Mossbauer spectra were measured at room temperature and liquid nitrogen temperature. Spectra consist of components related to iron-bearing phases with different content. Non-magnetic part was fitted with three quadrupole doublets. According to its parameters, we identified olivine, pyroxene, and traces of Fe3+ phases. Magnetic part consists of an iron-rich Fe-Ni alloy with hyperfine magnetic field similar to kamacite α-Fe(Ni,Co) and troilite. Main elements were also determined by X-ray fluorescence spectroscopy.

    The main focus is placed on operational experience in secondary system water chemistry (especially the steam generator) of the Ko-Ri nuclear power plant Unit 1, Republic of Korea, but primary side chemistry is also discussed. The major concern of secondary water chemistry in a PWR is that the condition of the steam generator be well maintained. Full flow deep bed condensate polishers have recently been installed and operation started in July 1982. Boric acid treatment of the steam generator was stopped and only the all volatile treatment method was used thereafter. A review of steam generator integrity, the chemistry control programme, secondary water quality, etc. is considered to be of great value regarding the operation of Unit 1 and future units now under startup testing or construction in the Republic of Korea.

    The protozoan Sarcocystis neurona is the primary cause of Equine Protozoal Myeloencephalitis (EPM). EPM or EPM-like illness has been reported in horses, sea otters, and several other mammals. The gamma interferon gene knockout (KO) mouse is often used as a model to study biology and discovery of new therapies against S. neurona because it is difficult to induce clinical EPM in other hosts, including horses. In the present study, infectivity of three life cycle stages (merozoites, bradyzoites, sporozoites) to KO mice and cell culture was studied. Two strains of KO mice (C57-black, and BALB/c-derived, referred here as black or white) were inoculated orally graded doses of S. neurona sporocysts; 12 sporocysts were infective to both strains of mice and all infected mice died or became ill within 70 days post-inoculation. Although there was no difference in infectivity of sporocysts to the two strains of KO mice, the disease was more severe in black mice. S. neurona bradyzoites were not infectious to KO mice and cell culture. S. neurona merozoites survived 120 min incubation in 0.25% trypsin, indicating that trypsin digestion can be used to recover S. neurona from tissues of acutely infected animals.

    Laser surface melting treatment used for the improvement of intergranular corrosion resistance of sensitized austenitic stainless steel weld metal was studied. As a result, it was revealed that as compared to untreated material, sensitization was improved widely and intergranular corrosion resistance was improved to a level of base metal when laser surface melting treatment of sensitized weld metal was carried out. Further, sensitization effect at a condition of laser traveling velocity of 0.00167m/s was slightly insufficient compared to that of laser traveling velocity above 0.00833m/s. This phenomena was caused due to the existence of {delta} ferrite that accelerates the precipitation of Cr carbides inside the laser treatment portion and together with this, the Cr carbides are precipitated in {delta}/{gamma} grain boundary due to the effect of laser heat cycle with insufficient cooling velocity and this has caused desensitization. 16 refs., 13 figs., 3 tabs.

    Full Text Available Abstract Background We and others have demonstrated previously that ghrelin receptor (GhrR knock out (KO mice fed a high fat diet (HFD have increased insulin sensitivity and metabolic flexibility relative to WT littermates. A striking feature of the HFD-fed GhrR KO mouse is the dramatic decrease in hepatic steatosis. To characterize further the underlying mechanisms of glucose homeostasis in GhrR KO mice, we conducted both hyperglycemic (HG and hyperinsulinemic-euglycemic (HI-E clamps. Additionally, we investigated tissue glucose uptake and specifically examined liver insulin sensitivity. Results Consistent with glucose tolerance-test data, in HG clamp experiments, GhrR KO mice showed a reduction in glucose-stimulated insulin release relative to WT littermates. Nevertheless, a robust 1st phase insulin secretion was still achieved, indicating that a healthy β-cell response is maintained. Additionally, GhrR KO mice demonstrated both a significantly increased glucose infusion rate and significantly reduced insulin requirement for maintenance of the HG clamp, consistent with their relative insulin sensitivity. In HI-E clamps, both LFD-fed and HFD-fed GhrR KO mice showed higher peripheral insulin sensitivity relative to WT littermates as indicated by a significant increase in insulin-stimulated glucose disposal (Rd, and decreased hepatic glucose production (HGP. HFD-fed GhrR KO mice showed a marked increase in peripheral tissue glucose uptake in a variety of tissues, including skeletal muscle, brown adipose tissue and white adipose tissue. GhrR KO mice fed a HFD also showed a modest, but significant decrease in conversion of pyruvate to glucose, as would be anticipated if these mice displayed increased liver insulin sensitivity. Additionally, the levels of UCP2 and UCP1 were reduced in the liver and BAT, respectively, in GhrR KO mice relative to WT mice. Conclusions These results indicate that improved glucose homeostasis of GhrR KO mice is

    2013-01-01

    Full Text Available Koç Holding is the most established conglomerate in Turkey. Th e company’s beginnings date from the mid 1920s, when Ahmet Vehbi Koç, founder of Koç Holding, had his first own company registered with the Ankara Chamber of Commerce. In 1932, Koç moved his business from his father’s store on Anafartalar Street to a new building, the first Koç Han, erected the same year on Çankırı Street Nr.13 in Ulus. Th e building’s designer was Swiss-Austrian architect Ernst Arnold Egli, who had come to Turkey only five years earlier upon invitation by the government to work as chief architect of the Ministry of National Education. During his stay, which lasted from 1927 until 1940, Egli realized about 40 projects and worked on many more. Koç Han is the rare example of a commercial building by Egli. At a time when the urban aspect of the old town center of Ankara consisted mostly of one-or two-storeyed stone-and-wood houses, the first Koç Han represented an altogether new building type for the town, in being a multipurpose edifice with space for shops at street level, with large storage facilities below ground, and providing off ices and housing on the upper fl oors. Th e functional rigor of the plan and the sober modernism of the building’s facades contrasted strongly with the architecture of the time. In this respect, the first Koç Han was a strong statement regarding Ahmet Vehbi Koç’s belief in a modern Turkey and to the contribution of the building’s architect, Ernst Arnold Egli, to this project.

    Cystic fibrosis (CF) is caused by mutations in the CF transmembrane conductance regulator (CFTR), an anion channel providing a major pathway for Cl− and HCO3− efflux across the apical membrane of the epithelium. In the intestine, CF manifests as obstructive syndromes, dysbiosis, inflammation, and an increased risk for gastrointestinal cancer. Cftr knockout (KO) mice recapitulate CF intestinal disease, including intestinal hyperproliferation. Previous studies using Cftr KO intestinal organoids (enteroids) indicate that crypt epithelium maintains an alkaline intracellular pH (pHi). We hypothesized that Cftr has a cell-autonomous role in downregulating pHi that is incompletely compensated by acid-base regulation in its absence. Here, 2′,7′-bis(2-carboxyethyl)-5(6)-carboxyfluorescein microfluorimetry of enteroids showed that Cftr KO crypt epithelium sustains an alkaline pHi and resistance to cell acidification relative to wild-type. Quantitative real-time PCR revealed that Cftr KO enteroids exhibit downregulated transcription of base (HCO3−)-loading proteins and upregulation of the basolateral membrane HCO3−-unloader anion exchanger 2 (Ae2). Although Cftr KO crypt epithelium had increased Ae2 expression and Ae2-mediated Cl−/HCO3− exchange with maximized gradients, it also had increased intracellular Cl− concentration relative to wild-type. Pharmacological reduction of intracellular Cl− concentration in Cftr KO crypt epithelium normalized pHi, which was largely Ae2-dependent. We conclude that Cftr KO crypt epithelium maintains an alkaline pHi as a consequence of losing both Cl− and HCO3− efflux, which impairs pHi regulation by Ae2. Retention of Cl− and an alkaline pHi in crypt epithelium may alter several cellular processes in the proliferative compartment of Cftr KO intestine. PMID:26542396

    Rechargeable potassium-oxygen (K-O 2 ) batteries promise to provide higher round-trip efficiency and cycle life than other alkali-oxygen batteries with satisfactory gravimetric energy density (935 Wh kg -1 ). Exploiting a strong electron-donating solvent, for example, dimethyl sulfoxide (DMSO) strongly stabilizes the discharge product (KO 2 ), resulting in significant improvement in electrode kinetics and chemical/electrochemical reversibility. The first DMSO-based K-O 2 battery demonstrates a much higher energy efficiency and stability than the glyme-based electrolyte. A universal KO 2 growth model is developed and it is demonstrated that the ideal solvent for K-O 2 batteries should strongly stabilize superoxide (strong donor ability) to obtain high electrode kinetics and reversibility while providing fast oxygen diffusion to achieve high discharge capacity. This work elucidates key electrolyte properties that control the efficiency and reversibility of K-O 2 batteries. © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

  4. Altered Immune Cytokine Expression Associated with KoRV B Infection and Season in Captive Koalas

    Higgins, Damien P.

    2016-01-01

    Koala (Phascolarctos cinereus) populations are increasingly vulnerable and one of the main threats is chlamydial infection. Koala retrovirus (KoRV) has been proposed as an underlying cause of the koala’s susceptibility to infection with Chlamydia and high rates of lymphoid neoplasia; however, the regionally ubiquitous, endogenous nature of this virus suggests that KoRV A infection is not sufficient for immune suppression to occur. A recently discovered exogenous variant of KoRV, KoRV B, has several structural elements that cause increased pathogenicity in related retroviruses and was associated with lymphoid neoplasia in one study. The present study assesses whether KoRV B infection is associated with alterations in immune function. Cytokine gene expression by mitogen stimulated lymphocytes of KoRV B positive (n = 5–6) and negative (n = 6–7) captive koalas was evaluated by qPCR four times (April 2014-February 2015) to control for seasonal variation. Key immune genes in the Th1 pathway (IFNγ, TNFα), Th2 pathway (IL 10, IL4, IL6) and Th17 pathway (IL17A), along with CD4:CD8 ratio, were assessed. KoRV B positive koalas showed significantly increased up-regulation of IL17A and IL10 in three out of four sampling periods and IFNγ, IL6, IL4 and TNFα in two out of four. IL17A is an immune marker for chlamydial pathogenesis in the koala; increased expression of IL17A in KoRV B positive koalas, and concurrent immune dysregulation, may explain the differences in susceptibility to chlamydial infection and severity of disease seen between individuals and populations. There was also marked seasonal variation in up-regulation for most of the cytokines and the CD4:CD8 ratio. The up-regulation in both Th1 and Th2 cytokines mirrors changes associated with immune dysregulation in humans and felids as a result of retroviral infections. This is the first report of altered immune expression in koalas infected by an exogenous variant of KoRV and also the first report of

However, an increase of deposition amount in response to the speed is required for the high-speed welding. Large-current low-spatter welding current region control was added. Units were integrated into a package by which the arc length is kept in short without dispersion of arc length for welding without defects such as undercut and unequal beads. In automobile industry, use of aluminum parts is extended for the light weight. The welding is very difficult, and automation is not so progressing in spite of the poor environment. Buckling of welding wire is easy to occur, and supply of wire is obstructed by the deposition of chipped powders on the torch cable, which stay within the contact chip resulting in the deposition. Dislocation of locus is easy to occur at the corner of rectangular pipe during the welding. By improving these troubles, an aluminum MIG welding robot package has been developed. 13 figs.

    The calcium/calmodulin-dependent protein kinase type IV (CaMKIV) is highly expressed in cerebellar cortical granule cells and deep nuclear neurons in the cerebellum. It mediates the phosphorylation and activation of the cAMP-dependent response element binding protein (CREB). In several paradigms CREB-dependent transcription is required for cellular events underlying long-term memory processes. Also, CaMKIV deficiency results in impaired long-term depression (LTD) induction in cerebellar cortex. To investigate the function of CaMKIV in the cerebellum, Wild-type (WT) and CaMKIV KO mice were tested with delay eyeblink conditioning. KO and WT mice did not differ in acquisition, but the KO mice showed a significantly lower conditioned response (CR) percentage than the WT mice in the retention testing and retraining period. The CR peak latencies for the two groups did not differ in acquisition but were shorter for the KO mice in the testing period. No significant differences were found between KO and WT mice in spontaneous eyeblink activity, auditory brainstem response (ABR) amplitudes, and tail-flick latency. The results suggest an important role for CaMKIV in long-term memory in the cerebellum. (c) 2009 APA, all rights reserved.

    The virulence of chlamydial infection in wild koalas is highly variable between individuals. Some koalas can be infected (PCR positive) with Chlamydia for long periods but remain asymptomatic, whereas others develop clinical disease. Chlamydia in the koala has traditionally been studied without regard to coinfection with other pathogens, although koalas are usually subject to infection with koala retrovirus (KoRV). Retroviruses can be immunosuppressive, and there is evidence of an immunosuppr...

    Full Text Available The paper seeks to establish who was the founder of the church of Saint George at Pološko and revise the conclusions of previous researchers regarding this issue. According to the opinion commonly adopted in the scholarly literature, Jovan Dragušin, a cousin of King Dušan, had merely undertaken the construction of church at Pološko, whereas his mother was responsible for the completion of construction and painting of frescoes in the church. Through an analysis of written and visual sources the conclusion is reached that the sole person responsible for the construction and painting of the church at Pološko was the nun Maria, the mother of Jovan Dragušin.

    The Korea Rare Isotope Accelerator, currently referred to as KoRIA, is briefly presented. The KoRIA facility is aimed to enable cutting-edge sciences in a wide range of fields. It consists of a 70 kW isotope separator on-line (ISOL) facility driven by a 70 MeV, 1 mA proton cyclotron and a 400 kW in-flight fragmentation (IFF) facility. The ISOL facility uses a superconducting (SC) linac for post-acceleration of rare isotopes up to about 18 MeV/u, while the SC linac of IFF facility is capable of accelerating uranium beams up to 200 MeV/u, 8 pμA and proton beams up to 600 MeV, 660 μA. Overall features of the KoRIA facility are presented with a focus on the accelerator design. (author)

  11. Oestrogen-deficient female aromatase knockout (ArKO) mice exhibit depressive-like symptomatology.

    Dalla, C; Antoniou, K; Papadopoulou-Daifoti, Z; Balthazart, J; Bakker, J

    2004-07-01

    We recently found that female aromatase knockout (ArKO) mice that are deficient in oestradiol due to a targeted mutation in the aromatase gene show deficits in sexual behaviour that cannot be corrected by adult treatment with oestrogens. We determined here whether these impairments are associated with changes in general levels of activity, anxiety or 'depressive-like' symptomatology due to chronic oestrogen deficiency. We also compared the neurochemical profile of ArKO and wild-type (WT) females, as oestrogens have been shown to modulate dopaminergic, serotonergic and noradrenergic brain activities. ArKO females did not differ from WT in spontaneous motor activity, exploration or anxiety. These findings are in line with the absence of major neurochemical alterations in hypothalamus, prefrontal cortex or striatum, which are involved in the expression of these behaviours. By contrast, ArKO females displayed decreased active behaviours, such as struggling and swimming, and increased passive behaviours, such as floating, in repeated sessions of the forced swim test, indicating that these females exhibit 'depressive-like' symptoms. Adult treatment with oestradiol did not reverse the behavioural deficits observed in the forced swim test, suggesting that they may be due to the absence of oestradiol during development. Accordingly, an increased serotonergic activity was observed in the hippocampus of ArKO females compared with WT, which was also not reversed by adult oestradiol treatment. The possible organizational role of oestradiol on the hippocampal serotonergic system and the 'depressive-like' profile of ArKO females provide new insights into the pathophysiology of depression and the increased vulnerability of women to depression.

  12. Increased adiposity, dysregulated glucose metabolism and systemic inflammation in Galectin-3 KO mice.

    Directory of Open Access Journals (Sweden)

    Jingbo Pang

    Full Text Available Obesity and type 2 diabetes are associated with increased production of Galectin-3 (Gal-3, a protein that modulates inflammation and clearance of glucose adducts. We used Lean and Diet-induced Obese (DIO WT and Gal-3 KO mice to investigate the role of Gal-3 in modulation of adiposity, glucose metabolism and inflammation. Deficiency of Gal-3 lead to age-dependent development of excess adiposity and systemic inflammation, as indicated by elevated production of acute-phase proteins, number of circulating pro-inflammatory Ly6C(high monocytes and development of neutrophilia, microcytic anemia and thrombocytosis in 20-week-old Lean and DIO male Gal-3 KO mice. This was associated with impaired fasting glucose, heightened response to a glucose tolerance test and reduced adipose tissue expression of adiponectin, Gal-12, ATGL and PPARγ, in the presence of maintained insulin sensitivity and hepatic expression of gluconeogenic enzymes in 20-week-old Gal-3 KO mice compared to their diet-matched WT controls. Expression of PGC-1α and FGF-21 in the liver of Lean Gal-3 KO mice was comparable to that observed in DIO animals. Impaired fasting glucose and altered responsiveness to a glucose load preceded development of excess adiposity and systemic inflammation, as demonstrated in 12-week-old Gal-3 KO mice. Finally, a role for the microflora in mediating the fasting hyperglycemia, but not the excessive response to a glucose load, of 12-week-old Gal-3 KO mice was demonstrated by administration of antibiotics. In conclusion, Gal-3 is an important modulator of glucose metabolism, adiposity and inflammation.

  13. Region-Specific Defects of Respiratory Capacities in the Ndufs4(KO Mouse Brain.

    Directory of Open Access Journals (Sweden)

    Ernst-Bernhard Kayser

    Full Text Available Lack of NDUFS4, a subunit of mitochondrial complex I (NADH:ubiquinone oxidoreductase, causes Leigh syndrome (LS, a progressive encephalomyopathy. Knocking out Ndufs4, either systemically or in brain only, elicits LS in mice. In patients as well as in KO mice distinct regions of the brain degenerate while surrounding tissue survives despite systemic complex I dysfunction. For the understanding of disease etiology and ultimately for the development of rationale treatments for LS, it appears important to uncover the mechanisms that govern focal neurodegeneration.Here we used the Ndufs4(KO mouse to investigate whether regional and temporal differences in respiratory capacity of the brain could be correlated with neurodegeneration. In the KO the respiratory capacity of synaptosomes from the degeneration prone regions olfactory bulb, brainstem and cerebellum was significantly decreased. The difference was measurable even before the onset of neurological symptoms. Furthermore, neither compensating nor exacerbating changes in glycolytic capacity of the synaptosomes were found. By contrast, the KO retained near normal levels of synaptosomal respiration in the degeneration-resistant/resilient "rest" of the brain. We also investigated non-synaptic mitochondria. The KO expectedly had diminished capacity for oxidative phosphorylation (state 3 respiration with complex I dependent substrate combinations pyruvate/malate and glutamate/malate but surprisingly had normal activity with α-ketoglutarate/malate. No correlation between oxidative phosphorylation (pyruvate/malate driven state 3 respiration and neurodegeneration was found: Notably, state 3 remained constant in the KO while in controls it tended to increase with time leading to significant differences between the genotypes in older mice in both vulnerable and resilient brain regions. Neither regional ROS damage, measured as HNE-modified protein, nor regional complex I stability, assessed by blue native

    Noda, K; Shibuya, S; Uesugi, T; Muramatsu, M; Kanazawa, M; Takada, E; Yamada, S

    2002-01-01

    Two advanced RF-knockout (RF-KO) slow-extraction methods have been developed at HIMAC in order to reduce the spill ripple for accurate heavy-ion cancer therapy: the dual frequency modulation (FM) method and the separated function method. As a result of simulations and experiments, it was verified that the spill ripple could be considerably reduced using these advanced methods, compared with the ordinary RF-KO method. The dual FM method and the separated function method bring about a low spill ripple within standard deviations of around 25% and of 15% during beam extraction within around 2 s, respectively, which are in good agreement with the simulation results.

    We propose that the spin-orbital-lattice coupled phenomena, widely known for the transition-metal oxides, can be realized in molecular solids, comprising of orbitally degenerate magnetic O 2 - ions. KO 2 is one such system. Using the first-principles electronic structure calculations, we set-up an effective spin-orbital superexchange model for the low-energy molecular bands and argue that many anomalous properties of KO 2 indeed replicate the status of its orbital system in different temperature regimes

    Highlights: ► In this study, helium supplying system was constructed. ► Preparation for heat transfer experiment in KO TBM condition using helium supplying system was progressed. ► To get more applicable results, test matrix was made to cover the condition for KO TBM. ► Using CFD code; CFX 11, validation and modification for system code GAMMA was performed. -- Abstract: By considering the requirements for a DEMO-relevant blanket concept, Korea (KO) has proposed a He cooled molten lithium (HCML) test blanket module (TBM) for testing in ITER. A performance analysis for the thermal–hydraulics and a safety analysis for the KO TBM have been carried out using a commercial CFD code, ANSYS-CFX, and a system code, GAMMA (GAs multicomponent mixture analysis), which was developed by the gas cooled reactor in Korea. To verify the codes, a preliminary study was performed by Lee using a single TBM first wall (FW) mock-up made from the same material as the KO TBM, ferritic martensitic steel, using a 6 MPa nitrogen gas loop. The test was performed at pressures of 1.1, 1.9 and 2.9 MPa, and under various ranges of flow rate from 0.0105 to 0.0407 kg/s with a constant wall temperature condition. In the present study, a thermal–hydraulic test was performed with the newly constructed helium supplying system, in which the design pressure and temperature were 9 MPa and 500 °C, respectively. In the experiment, the same mock-up was used, and the test was performed under the conditions of 3 MPa pressure, 30 °C inlet temperature and 70 m/s helium velocity, which are almost same conditions of the KO TBM FW. One side of the mock-up was heated with a constant heat flux of 0.3–0.5 MW/m 2 using a graphite heating system, KoHLT-2 (Korea heat load test facility-2). Because the comparison result between CFX 11 and GAMMA showed a difference tendency, the modification of heat transfer correlation included in GAMMA was performed. And the modified GAMMA showed the strong parity with CFX

  5. Dose-Dependent Rescue of KO Amelogenin Enamel by Transgenes in Vivo.

    Mice lacking amelogenin (KO) have hypoplastic enamel. Overexpression of the most abundant amelogenin splice variant M180 and LRAP transgenes can substantially improve KO enamel, but only ~40% of the incisor thickness is recovered and the prisms are not as tightly woven as in WT enamel. This implies that the compositional complexity of the enamel matrix is required for different aspects of enamel formation, such as organizational structure and thickness. The question arises, therefore, how important the ratio of different matrix components, and in particular amelogenin splice products, is in enamel formation. Can optimal expression levels of amelogenin transgenes representing both the most abundant splice variants and cleavage product at protein levels similar to that of WT improve the enamel phenotype of KO mice? Addressing this question, our objective was here to understand dosage effects of amelogenin transgenes ( Tg ) representing the major splice variants M180 and LRAP and cleavage product CTRNC on enamel properties. Amelogenin KO mice were mated with M180 Tg , CTRNC Tg and LRAP Tg mice to generate M180 Tg and CTRNC Tg double transgene and M180 Tg , CTRNC Tg , LRAP Tg triple transgene mice with transgene hemizygosity (on one allelle) or homozygosity (on both alleles). Transgene homo- vs. hemizygosity was determined by qPCR and relative transgene expression confirmed by Western blot. Enamel volume and mineral density were analyzed by microCT, thickness and structure by SEM, and mechanical properties by Vickers microhardness testing. There were no differences in incisor enamel thickness between amelogenin KO mice with three or two different transgenes, but mice homozygous for a given transgene had significantly thinner enamel than mice hemizygous for the transgene ( p structure, but only up to a maximum of ~80% that of molar and ~40% that of incisor wild-type enamel.

    Primary evidence for novel estrogen signaling pathways is based upon well-documented estrogenic responses not inhibited by estrogen receptor antagonists. In addition to 17beta-E2, the catechol estrogen 4-hydroxyestradiol (4OHE2) has been shown to elicit biological responses independent of classical estrogen receptors in estrogen receptor-alpha knockout (ERalphaKO) mice. Consequently, our research was designed to biochemically characterize the protein(s) that could be mediating the biological effects of catechol estrogens using enzymatically synthesized, radiolabeled 4-hydroxyestrone (4OHE1) and 4OHE2. Scatchard analyses identified a single class of high-affinity (K(d) approximately 1.6 nM), saturable cytosolic binding sites in several ERalphaKO estrogen-responsive tissues. Specific catechol estrogen binding was competitively inhibited by unlabeled catechol estrogens, but not by 17beta-E2 or the estrogen receptor antagonist ICI 182,780. Tissue distribution studies indicated significant binding differences both within and among various tissues in wild-type, ERalphaKO, and aromatase knockout female mice. Ligand metabolism experiments revealed extensive metabolism of labeled catechol estrogen, suggesting that catechol estrogen metabolites were responsible for the specific binding. Collectively, our data provide compelling evidence for the interaction of catechol estrogen metabolites with a novel binding protein that exhibits high affinity, specificity, and selective tissue distribution. The extensive biochemical characterization of this binding protein indicates that this protein may be a receptor, and thus may mediate ERalpha/beta-independent effects of catechol estrogens and their metabolites.

    Algae biomass is a potential raw material for the production of biofuels and other chemicals. In this study, biomass of the marine algae, Ulva lactuca, Gelidium amansii,Laminaria japonica, and Sargassum fulvellum, was treated with acid and commercially available hydrolytic enzymes. The hydrolysates contained glucose, mannose, galactose, and mannitol, among other sugars, at different ratios. The Laminaria japonica hydrolysate contained up to 30.5% mannitol and 6.98% glucose in the hydrolysate solids. Ethanogenic recombinant Escherichia coli KO11 was able to utilize both mannitol and glucose and produced 0.4g ethanol per g of carbohydrate when cultured in L. japonica hydrolysate supplemented with Luria-Bertani medium and hydrolytic enzymes. The strategy of acid hydrolysis followed by simultaneous enzyme treatment and inoculation with E. coli KO11 could be a viable strategy to produce ethanol from marine alga biomass.

    This paper provides a discussion of the lessons learned from operational experience and the future plans to improve performance of the Ko-Ri plant. To operate nuclear power plants safely with good performance is the only way to mitigate the negative image of nuclear power generation to the public and to enhance the economical benefit compared to other electrical generation method. Therefore, in a continuous effort to overcome a negative challenge from outside, we have driven an aggressive 'OCTF' campaign as part of safety. As a result of our efforts, the following remarkable achievements have been accomplished. (1) 3 times of OCTF during recent three years (2) Selected twice as a top notch power plant on the list of NEI magazine in terms of plant capacity factor (3) No scram recorded in 1997 for all 4 units at Ko-Ri site. Ko-Ri is now undergoing the large scale plant betterment projects for retaking-off our operating performance to the level of new challenge target. Such improvement of critical components in the reactor coolant system and turbine system greatly contribute to increase the safety and reliability of the plant and to shortening of the planned outage period as well as to reduction of radiation exposure and radwaste.

    Planning, preparation, conductance, and evaluation of field tests are reported to determine the explosive hazards associated with the combining of the sodium-potassium eutectic alloy (NaK) with the superoxide of potassium (KO 2 ) under various conditions of state, contamination, and detonation initiation. The planning and preparation was conducted by Aerojet Nuclear Company (ANC) at the Idaho National Engineering Laboratory, and the explosive hazards testing was done by Cook Associates, Inc., at IRECO Chemicals Pelican Point Research and Development facility in Utah. The test results showed that binary combinations of pure NaK and KO 2 could not be made to detonate, although the mixtures will spontaneously ignite and burn. However, tertiary combinations of NaK, KO 2 plus a water or hydrocarbon contaminant produced explosive hazards under a variety of conditions. The work was performed as part of the Decontamination and Decommissioning (D and D) of the first Experimental Breeder Reactor (EBR-I) and was funded by 189c I-215. (U.S.)

    EPICS (Experimental Physics and Industrial Control System) is a collection of software tools collaboratively developed which can be integrated to provide a comprehensive and scalable control system. Currently there is an increase in use of such systems in large Physics experiments like KSTAR, ITER and DAIC (Daejeon Accelerator Ion Complex). The Korean heat load test facility (KoHLT-EB) was installed at KAERI. This facility is utilized for a qualification test of the plasma facing component (PFC) for the ITER first wall and DEMO divertor, and the thermo-hydraulic experiments. The existing data acquisition device was Agilent 34980A multifunction switch and measurement unit and controlled by Agilent VEE. In the present paper, we report the EPICS based newly upgraded KoHLT-EB DAQ system which is the advanced data acquisition system using FPGA-based reconfigurable DAQ devices like compact RIO. The operator interface of KoHLT-EB DAQ system is composed of Control-System Studio (CSS) and another server is able to archive the related data using the standalone archive tool and the archiveviewer can retrieve that data at any time in the infra-network.

    Full Text Available In the first part of the paper the aim is to provide the reader with a theoretical insight into models of government structure at the local level and provide evidence from European countries that underwent reforms during the second half of the 20th century. In the Slovak Republic (Slovakia the renewal of local self-government in 1990 brought changes to the administrative boundary map with more than 200 municipalities reestablished bringing the current number to 2,929 local administrative units. This has resulted in some discussion regarding a reduction in the number of local government units in this country. The second part of the paper is focused on Košice; the second largest city in Slovakia with 234,000 in­habitants. The city is organised at two administrative levels; one covering the whole city, the other covering 22 wards. When compared to cities of a similar size, Košice has been criticised for its high number of city wards and councillors, with the concomitant financial inefficiency it can bring. There has been an ongoing debate on reducing their number since 2010. The paper reports on the search for an admin­istrative structure that would best tailor to the citizens' needs and provide effective management in Košice. It uses traditional methods of qualitative research (historical method, content analysis and syn­thesis accompanied by statistical data organised in tables and figures.

    This paper provides a discussion of the lessons learned from operational experience and the future plans to improve performance of the Ko-Ri plant. To operate nuclear power plants safely with good performance is the only way to mitigate the negative image of nuclear power generation to the public and to enhance the economical benefit compared to other electrical generation method. Therefore, in a continuous effort to overcome a negative challenge from outside, we have driven an aggressive 'OCTF' campaign as part of safety. As a result of our efforts, the following remarkable achievements have been accomplished. (1) 3 times of OCTF during recent three years (2) Selected twice as a top notch power plant on the list of NEI magazine in terms of plant capacity factor (3) No scram recorded in 1997 for all 4 units at Ko-Ri site. Ko-Ri is now undergoing the large scale plant betterment projects for retaking-off our operating performance to the level of new challenge target. Such improvement of critical components in the reactor coolant system and turbine system greatly contribute to increase the safety and reliability of the plant and to shortening of the planned outage period as well as to reduction of radiation exposure and radwaste.

    AsiaFlux, the Asian arm of FLUXNET, held the Second International Workshop on Advanced Flux Network and Flux Evaluation in Jeju Island, Korea on 9-11 January 2002. In order to facilitate comprehensive Asia-wide studies of ecosystem fluxes, the meeting launched KoFlux, a new Korean regional network of long-term micrometeorological flux sites. For a successful assessment of carbon exchange between terrestrial ecosystems and the atmosphere, an accurate measurement of surface fluxes of energy and water is one of the prerequisites. During the 7th Global Energy and Water Cycle Experiment (GEWEX) Asian Monsoon Experiment (GAME) held in Nagoya, Japan on 1-2 October 2001, the Implementation Committee of the Coordinated Enhanced Observing Period (CEOP) was established. One of the immediate tasks of CEOP was and is to identify the reference sites to monitor energy and water fluxes over the Asian continent. Subsequently, to advance the regional and global network of these reference sites in the context of both FLUXNET and CEOP, the Korean flux community has re-organized the available resources to establish a new regional network, KoFlux. We have built up domestic network sites (equipped with wind profiler and radiosonde measurements) over deciduous and coniferous forests, urban and rural rice paddies and coastal farmland. As an outreach through collaborations with research groups in Japan, China and Thailand, we also proposed international flux sites at ecologically and climatologically important locations such as a prairie on the Tibetan plateau, tropical forest with mixed and rapid land use change in northern Thailand. Several sites in KoFlux already begun to accumulate interesting data and some highlights are presented at the meeting. The sciences generated by flux networks in other continents have proven the worthiness of a global array of micrometeorological flux towers. It is our intent that the launch of KoFlux would encourage other scientists to initiate and

    Malaria is a deadly infectious disease affecting millions of people in tropical and sub-tropical countries. Among the five species of Plasmodium parasites that infect humans, Plasmodium falciparum accounts for the highest morbidity and mortality associated with malaria. Since humans are the only natural hosts for P. falciparum, the lack of convenient animal models has hindered the understanding of disease pathogenesis and prompted the need of testing anti-malarial drugs and vaccines directly in human trials. Humanized mice hosting human cells represent new pre-clinical models for infectious diseases that affect only humans. In this study, the ability of human-immune-system humanized HLA-DR4.RagKO.IL2RγcKO.NOD (DRAG) mice to sustain infection with P. falciparum was explored. Four week-old DRAG mice were infused with HLA-matched human haematopoietic stem cells (HSC) and examined for reconstitution of human liver cells and erythrocytes. Upon challenge with infectious P. falciparum sporozoites (NF54 strain) humanized DRAG mice were examined for liver stage infection, blood stage infection, and transmission to Anopheles stephensi mosquitoes. Humanized DRAG mice reconstituted human hepatocytes, Kupffer cells, liver endothelial cells, and erythrocytes. Upon intravenous challenge with P. falciparum sporozoites, DRAG mice sustained liver to blood stage infection (average 3-5 parasites/microlitre blood) and allowed transmission to An. stephensi mosquitoes. Infected DRAG mice elicited antibody and cellular responses to the blood stage parasites and self-cured the infection by day 45 post-challenge. DRAG mice represent the first human-immune-system humanized mouse model that sustains the complex vertebrate life cycle of P. falciparum without the need of exogenous injection of human hepatocytes/erythrocytes or P. falciparum parasite adaptation. The ability of DRAG mice to elicit specific human immune responses to P. falciparum parasites may help deciphering immune correlates

    Amomum tsao-ko is a commercial plant that used for various purposes in medicinal and food industries. For the present investigation, 44 germplasm samples were collected from Jinping County of Yunnan Province. Clusters analysis and 2-dimensional principal component analysis (PCA) was used to represent the genetic relations among Amomum tsao-ko by using simple sequence repeat (SSR) markers. Clustering analysis clearly distinguished the samples groups. Two major clusters were formed; first (Cluster I) consisted of 34 individuals, the second (Cluster II) consisted of 10 individuals, Cluster I as the main group contained multiple sub-clusters. PCA also showed 2 groups: PCA Group 1 included 29 individuals, PCA Group 2 included 12 individuals, consistent with the results of cluster analysis. The purpose of the present investigation was to provide information on genetic relationship of Amomum tsao-ko germplasm resources in main producing areas, also provide a theoretical basis for the protection and utilization of Amomum tsao-ko resources.

    Full Text Available The metallurgic activity of Kovohuty Krompachy (Non-ferrous Metal Works in Krompachy in the past left its visible devastation sign on the nature. It was evident that the dispersion of some elements, especially Cu, Pb, Sb and As, in the air was caused by the activity of metal works and their point sources. The properties of these metals may cause changes in health of biological objects as a result of long-term effect on the natural or communal spheres. After the treatment activities in ŽB Rudòany enterprise ended, Kovohuty Krompachy bought a treatment concentrate from ŽB Rudòany, which was freed from mercury. This concentrate still contained a lot of Cu, Sb, As, Bi and it should have been processed in Kovohuty to the so called black copper. The Municipality of the city of Košice, its department of the environment, expressed its apprehension of the possibility that this processing could cause that heavy metals may be spread in a direction of prevailing winds, i.e. south-east direction, where the city of Košice is situated. This was a reason for a task to monitor movement and occurrence of heavy metals on the route between Krompachy and Košice, as well as to monitor the share of individual sources of pollution on the quality of air in Košice urban agglomeration.Two methods applied were chosen for research purposes. The dust deposition was monitored, i.e. dust that sediments from air, its value is stated in g.m-2. 30 days-1. Another method used was the so called aspiration dust content, when air is sucked through a suitable filter and the value is stated in mg.m-3. In the given locality, there were 15 newly built or renovated sedimentation stations, where samples of sedimented dust were taken by the end of 1999 in six stages. They are marked by letters A to F. The samples of dust were analysed by atomic absorption spectrophotometry. The presented paper shows the results of phases A and D, or B and D.Aspiration method was used for fine

    Full Text Available The purpose of this paper is to define the basic issues and opportunities challenging the modern development of the Municipality of Dubrovačko Primorje, their causes and effects. The processes of depopulation affected this poorly developed rural region since 1960s, which had been influenced by various factors: development polarisation caused by intensive development of tourism, the poor traffic infrastructure in the highland-area of the Municipality and the unsolved water supply issue. In 1990s a series of events intensified negative demographic trends as follows: aggression on Croatia, occupation during which residential, economic and infrastructural buildings were destroyed and burnt, as well as an earthquake which happened after the return of the refugees. The long-lasting rural emigration from this region towards Dubrovnik caused not only an instantaneous decrease of population but also a contraction of the renewing basis and an accelerated decrease of natural growth in the Municipality of Dubrovačko Primorje. In that way the emigrational depopulation as a consequence of a specific socioeconomic development, became the cause of the current biological depopulation. The intensity of the depopulation processes has been established by an analysis of a total population dynamics and the changes in biological and economic population structure. The conclusion of the study indicates activities which have promising development in the Municipality of Dubrovačko Primorje and which might partly stop the negative demographic trends. Those are mainly traditional activities in this region which are not commercially used enough. They should prevent any further emigration and perhaps even attract those who immigrated, back to their place of birth.

    A new RF-KO (RF knockout) system for the single bunch mode operation of a storage ring has been developed. The knockout signal is modulated by the sum signal of the RF acceleration frequency of the storage ring and a bunch selection signal. We do not need any special device or a timing unit with this method. We obtain a high purity of bunch structure in a short knock out time. The single bunch impurity of 0.2% has been achieved.

    Gene knockout is the most powerful tool for determination of gene function or permanent modification of the phenotypic characteristics of an animal. Existing methods for gene disruption are limited by their efficiency, time required for completion and potential for confounding off-target effects. In this study, a rapid single-step approach to knockout of a targeted gene in mice using zinc-finger nucleases (ZFNs) was demonstrated for generation of mutant (knockout; KO) alleles. Specifically, ZFNs to target the sodium/calcium/potassium exchanger3 (NCKX3) gene in C57bl/6j were designed using the concept of this approach. NCKX3 KO mice were generated and the phenotypic characterization and molecular regulation of active calcium transporting genes was assessed when mice were fed different calcium diets during growth. General phenotypes such as body weight and plasma ion level showed no distinct abnormalities. Thus, the potassium/sodium/calcium exchanger of NCKX3 KO mice proceeded normally in this study. As a result, the compensatory molecular regulation of this mechanism was elucidated. Renal TRPV5 mRNA of NCKX3 KO mice increased in both male and female mice. Expression of TRPV6 mRNA was only down-regulated in the duodenum of male KO mice. Renal- and duodenal expression of PTHR and VDR were not changed; however, GR mRNA expression was increased in the kidney of NCKX3 KO mice. Depletion of the NCKX3 gene in a KO mouse model showed loss of bone mineral contents and increased plasma parathyroid hormone, suggesting that NCKX3 may play a role in regulating calcium homeostasis.

  14. Further Development of Ko Displacement Theory for Deformed Shape Predictions of Nonuniform Aerospace Structures

    Ko, William L.; Fleischer, Van Tran

    2009-01-01

    The Ko displacement theory previously formulated for deformed shape predictions of nonuniform beam structures is further developed mathematically. The further-developed displacement equations are expressed explicitly in terms of geometrical parameters of the beam and bending strains at equally spaced strain-sensing stations along the multiplexed fiber-optic sensor line installed on the bottom surface of the beam. The bending strain data can then be input into the displacement equations for calculations of local slopes, deflections, and cross-sectional twist angles for generating the overall deformed shapes of the nonuniform beam. The further-developed displacement theory can also be applied to the deformed shape predictions of nonuniform two-point supported beams, nonuniform panels, nonuniform aircraft wings and fuselages, and so forth. The high degree of accuracy of the further-developed displacement theory for nonuniform beams is validated by finite-element analysis of various nonuniform beam structures. Such structures include tapered tubular beams, depth-tapered unswept and swept wing boxes, width-tapered wing boxes, and double-tapered wing boxes, all under combined bending and torsional loads. The Ko displacement theory, combined with the fiber-optic strain-sensing system, provide a powerful tool for in-flight deformed shape monitoring of unmanned aerospace vehicles by ground-based pilots to maintain safe flights.

    Full Text Available Background and Purpose: Forest cultures in continental part of Croatia are mainly based on bracken-covered areas and moors on deserted agriculture soils and pastures. Successful afforestation i.e. establishment of forest cultures depends among other things on the understanding of habitats and ecology of forest trees. The choice of best species of forest trees for afforestation needs to be based on the research in soil and climate characteristics of target habitats. The aims of this research were to show mesoclimatic characteristics of Ličko sredogorje and microclimatic and pedological characteristics of Ličko polje. Also, based on habitat characteristics and ecology of forest trees, the aim was to determine species of forest trees suitable for afforestation of bracken-covered areas. Materials and Methods: Climate, microclimate, pedological and plant nutrition researches were done at the area of Lika highlands. Climate analysis was done according to air temperatures, amount of precipitation, relative air humidity and other climate elements and appearances. Composite soil samples were taken from the depth of 0-30 cm in order to determine plant nutrition potential. Samples were prepared for further analysis in the laboratory. Results: The highest average annual air temperature of 9.6 °C was found at weather station Gračac and the lowest at Korenica station (8.1 °C. Average amount of precipitation for this region was around 1500 mm. Monthly rain factors were ranging from arid to perhumid. Considering thermal character of the climate, the area has moderately warm climate. Average volumetric soil humidity is 14.2 %. Soil has strong acid reaction, is very humus, good to richly supplied with total nitrogen, content of physiologically active phosphorus and potassium is low, and C/N ration normal. Conclusions: According to habitat characteristics in the area of Ličko sredogorje and ecological demands of forest tree species, forest cultures of Common

The objective of this research was to investigate and compare changes of postnatal neuronal NOS (nNOS) expression in the hippocampus of male fragile X mental retardation 1 gene knockout mice (FMR1 KO mice, the animal model of FXS) and male wild-type mice (WT) at postnatal day 7 (P7), P14, P21, and P28. nNOS mRNA levels were analyzed by real-time quantitative PCR (N = 4-7) and nNOS protein was estimated by Western blot (N = 3) and immunohistochemistry (N = 1). In the PCR assessment, primers 5′-GTGGCCATCGTGTCCTACCATAC-3′ and 5′-GTTTCGAGGCAGGTGGAAGCTA-3′ were used for the detection of nNOS and primers 5′-CCGTTTCTCCTGGCTCAGTTTA-3′ and 5′-CCCCAATACCACATCATCCAT-3′ were used for the detection of β-actin. Compared to the WT group, nNOS mRNA expression was significantly decreased in FMR1 KO mice at P21 (KO: 0.2857 ± 0.0150, WT: 0.5646 ± 0.0657; P < 0.05). Consistently, nNOS immunoreactivity also revealed reduced staining intensity at P21 in the FMR1 KO group. Western blot analysis validated the immunostaining results by demonstrating a significant reduction in nNOS protein levels in the FMR1 KO group compared to the WT group at P21 (KO: 0.3015 ± 0.0897, WT: 1.7542 ± 0.5455; P < 0.05). These results suggest that nNOS was involved in the postnatal development of the hippocampus in FXS and impaired NO production may retard spine maturation in FXS

    Trichomonosis, caused by the flagellate protozoan Trichomonas vaginalis, is the most common non-viral sexually transmitted disease (STD) and 5-nitroimidazole drugs are used for the treatment. However, a growing number of T. vaginalis isolates are resistant to these drugs, which make it becomes an urgent issue. The current study was designed to evaluate the anti-T. vaginalis activity of the essential oil from A. tsao-ko used in traditional Chinese medicine and as a spice and its main component, geraniol. The anti-T. vaginalis activities of A. tsao-ko essential oil and geraniol were evaluated by the minimum lethal concentration (MLC) and 50% inhibitory concentration (IC50) in vitro. The morphological changes of T. vaginalis were observed by transmission electron microscopy (TEM). Additionally, sub-MLC concentration treatment with sub-MLC A. tsao-ko essential oil and geraniol was also performed. This study shows that MLC/IC50 of A. tsao-ko essential oil was 44.97 µg/ml/22.49 µg/ml for T. vaginalis isolate Tv1, and 89.93 µg/ml/44.97 µg/ml for T. vaginalis isolate Tv2. Those of geraniol were 342.96 µg/ml/171.48 µg/ml, respectively. After A. tsao-ko essential oil or geraniol treatment, obvious similar morphological changes of T. vaginalis were observed by TEM: the nuclear membrane was damaged, nuclei were dissolved, and the chromatin was accumulated; in the cytoplasm, numerous vacuoles appeared, rough endoplasmic reticulum dilated, the number of ribosomes were reduced, organelles disintegrated, the cell membrane was partially damaged, with cytoplasmic leakage, and cell disintegration was observed. The action time did not increase the effect of A. tsao-ko essential oil or geraniol against T. vaginalis, as no significant difference was observed after sub-MLC concentration treatment for 1, 3, and 5 h with A. tsao-ko essential oil and geraniol. The study describes the first report on the activity and morphological changes of A. tsao-ko essential oil and

    The 57Fe Mössbauer spectroscopy method was used to investigate iron-containing compounds in town Košice meteorite fallen on the territory of Slovakia in February 2010. The results showed that the Mössbauer spectra consisted of magnetic and non-magnetic components related to different iron-bearing phases. The non-magnetic phase includes olivine, pyroxene and traces of Fe3+ phase and the magnetic component comprises troilite (FeS) and iron-rich Fe-Ni alloy with hyperfine magnetic field typical for kamacite. Samples from meteorite were obtained in powder from different depths to inspect its heterogeneous composition. The content of kamacite increases to the detriment of troilite from the surface toward the centre of the sample. Measurements at liquid nitrogen temperature confirmed phase composition of investigated meteorite. Main constituent elements of studied samples were also determined by X-ray fluorescence analysis.

    Full Text Available In this paper I explore some of the connections the Slovene poet Srečko Kosovel (1904–1926 surmised between himself and the Indian poet Rabindranath Tagore (1861–1941. I argue that what linked the two poets into a joint framework across the vastly different cultural and politico-geographic space was not just the fact that Kosovel read Tagore and took inspiration from the Bengali poet at the height of Tagore’s reputation in continental Europe, but that they shared a number of preoccupations, informed by their respective historical positioning. Both wrote from a profound awareness of their region’s subjugated status and endorsed an anti-imperialist stance that rejected nationalism as a viable means of liberation, embracing instead a creative universalist ideal.

    Highlights: ▶ Comparison of the DRAGON 4 and CORD-2 calculation of the NPP Krško 16 × 16 fuel assembly has been performed. ▶ Two different enrichments (4.60% and 4.95%), three IFBA configurations (0, 64 and 116 IFBAs) and the burnup up to 60,000 MWd/tU were considered. ▶ Comparison shows that the agreement in the results of both codes is very good. ▶ Regarding efficiency, one CORD-2 assembly depletion calculation takes about 3 min of the CPU time on the typical PC, while the DRAGON calculation runs more than 25 h. - Abstract: The geometry of the reactor core is usually too complex to be solved in one step. Therefore, a solution for the whole core in 3-D geometry is sought in several steps, where some kind of homogenization procedure of neutron few-group cross sections is applied. Usually, assembly-homogenized effective two-group cross sections are determined, which are suitable for solving the diffusion equation for the whole core by a coarse mesh nodal methods. In this paper DRAGON 4 and CORD-2 codes are used for the calculation of NPP Krško 16 × 16 fuel assemblies without and with IFBA rods. DRAGON code was selected, since it can use the same cross-section library as the WIMS-D5 code employed in the CORD-2 system. Different results arise therefore solely from the different models used in the calculations. The heterogeneous depletion calculation was performed up to burnup of 60,000 MWd/tU. Results of both codes are compared for the infinite multiplication factor, fast to thermal spectral ratio and pin power distributions.

    Software-defined optical networking (SDON) will become the next generation optical network architecture. However, the optical layer and control layer of SDON are vulnerable to cyberattacks. While, data encryption is an effective method to minimize the negative effects of cyberattacks, secure key interchange is its major challenge which can be addressed by the quantum key distribution (QKD) technique. Hence, in this paper we discuss the integration of QKD with WDM optical networks to secure the SDON architecture by introducing a novel key on demand (KoD) scheme which is enabled by a novel routing, wavelength and key assignment (RWKA) algorithm. The QKD over SDON with KoD model follows two steps to provide security: i) quantum key pools (QKPs) construction for securing the control channels (CChs) and data channels (DChs); ii) the KoD scheme uses RWKA algorithm to allocate and update secret keys for different security requirements. To test our model, we define a security probability index which measures the security gain in CChs and DChs. Simulation results indicate that the security performance of CChs and DChs can be enhanced by provisioning sufficient secret keys in QKPs and performing key-updating considering potential cyberattacks. Also, KoD is beneficial to achieve a positive balance between security requirements and key resource usage.

  6. The Growth Hormone Receptor Gene-Disrupted (GHR-KO) Mouse Fails to Respond to an Intermittent Fasting (IF) Diet

    SUMMARY The interaction of longevity-conferring genes with longevity-conferring diets is poorly understood. The growth hormone receptor gene-disrupted (GHR-KO) mouse is long-lived; and this longevity is not responsive to 30% caloric restriction (CR), in contrast to wild-type animals from the same strain. To determine whether this may have been limited to a particular level of dietary restriction (DR), we subjected GHR-KO mice to a different dietary restriction regimen, an intermittent fasting (IF) diet. The IF diet increased the survivorship and improved insulin sensitivity of normal males, but failed to affect either parameter in GHR-KO mice. From the results of two paradigms of dietary restriction we postulate that GHR-KO mice would be resistant to any manner of DR; potentially due to their inability to further enhance insulin sensitivity. Insulin sensitivity may be a mechanism and/or a marker of the lifespan-extending potential of an intervention. PMID:19747233

    High-coverage whole-genome sequencing data of a single ethnicity can provide a useful catalogue of population-specific genetic variations, and provides a critical resource that can be used to more accurately identify pathogenic genetic variants. We report a comprehensive analysis of the Korean population, and present the Korean National Standard Reference Variome (KoVariome). As a part of the Korean Personal Genome Project (KPGP), we constructed the KoVariome database using 5.5 terabases of whole genome sequence data from 50 healthy Korean individuals in order to characterize the benign ethnicity-relevant genetic variation present in the Korean population. In total, KoVariome includes 12.7M single-nucleotide variants (SNVs), 1.7M short insertions and deletions (indels), 4K structural variations (SVs), and 3.6K copy number variations (CNVs). Among them, 2.4M (19%) SNVs and 0.4M (24%) indels were identified as novel. We also discovered selective enrichment of 3.8M SNVs and 0.5M indels in Korean individuals, which were used to filter out 1,271 coding-SNVs not originally removed from the 1,000 Genomes Project when prioritizing disease-causing variants. KoVariome health records were used to identify novel disease-causing variants in the Korean population, demonstrating the value of high-quality ethnic variation databases for the accurate interpretation of individual genomes and the precise characterization of genetic variations.

    The RF-knockout (RF-KO) slow-extraction method with frequency modulation (FM) and amplitude modulation (AM) has brought high-accuracy irradiation to the treatment of a cancer tumor moving with respiration, because of a quick response to beam start/stop. However, a beam spill extracted from a synchrotron ring through RF-KO slow-extraction has a huge ripple with a frequency of around 1 kHz related to the FM. The spill ripple will disturb the lateral dose distribution in the beam scanning methods. Thus, the source of the spill ripple has been investigated through experiments and simulations. There are two tune regions for the extraction process through the RF-KO method: the extraction region and the diffusion region. The particles in the extraction region can be extracted due to amplitude growth through the transverse RF field, only when its frequency matches with the tune in the extraction region. For a large chromaticity, however, the particles in the extraction region can be extracted through the synchrotron oscillation, even when the frequency does not match with the tune in the extraction region. Thus, the spill structure during one period of the FM strongly depends on the horizontal chromaticity. They are repeated with the repetition frequency of the FM, which is the very source of the spill ripple in the RF-KO method

    The magnetic susceptibilities of KO 3 , RbO 3 and CsO 3 have been determined between 3.6 and 250 K. Above 50 K Curie-Weiss behaviour is observed. Magnetic moments of 1.74 μ B (KO 3 , CsO 3 ) and 1.80 μ B (RbO 3 ) calculated from the Curie-Weiss straight lines correspond with spin-only moments expected for isolated O 3 - species with one unpaired electron. The Weiss constants Θ are -34 K (KO 3 ), -23 K (RbO 3 ) and -10 K (CsO 3 ). The low temperature behaviour of KO 3 and RbO 3 (broad maxima in susceptibility at 20 and 17 K, respectively, and minima at 6 K) is typical of systems which show with decreasing temperature low-dimensional antiferromagnetic and three-dimensional magnetic ordering. Inspecting the intermolecular distances between oxygen atoms the pathways of exchange interactions are discussed. (author)

Again Jews are accused of causing damage to Poles, and the language of those statements is very much like in the discourse before the Council.   Żydzi w dyskursie Kościoła katolickiego Artykuł opisuje ważne zmiany w dyskursie Kościoła katolickiego w odniesieniu do wyznawców judaizmu, które pojawiły się po Soborze Watykańskim II. Jedną z nich jest różnica pomiędzy stanem tekstów w dwóch różnych momentach: przed i po soborze. Dlatego pierwszą część artykułu autorka poświęca charakterystyce przedsoborowego (i w większości przedwojennego dyskursu na temat Żydów, a część drugą – głównym kierunkom zmian spowodowanym realizacją postulatów soboru. Część trzecia pokazuje objawy kontynuacji starych, głęboko zakorzenionych schematów. Analiza częściowo odnosi się do ogólnych tekstów Kościoła, a częściowo do tekstów Kościoła publikowanych w Polsce. Polski przedsoborowy dyskurs o Żydach był wyjątkowo negatywny. Liturgia katolicka przedstawiała Żydów jako tych, którzy torturowali i zabili Jezusa (mit bogobójcy. W kazaniach, listach duszpasterskich i katolickiej prasie Żydów pokazywano jako wrogów nie tylko chrześcijan, lecz szczególnie Polaków, ponieważ Kościół w Polsce zaangażował się w kreowanie narodowo i religijnie homogenicznego kraju pod sloganem „Polska dla Polaków”. Reprodukowano wszystkie tradycyjne mity (Żydzi jako szkodnicy, spiskowcy, rozpustnicy itd. Używano wiele środków lingwistycznych, by zdegradować Żydów, np. zdrobnienia, animalizację (czyli mówienie o Żydach jako o zwierzętach czy tak zwany kakofemizm (czyli używanie słów o pejoratywnym znaczeniu, aby sprowokować uczucie moralnego i fizycznego obrzydzenia.

Ponieważ astma jest chorobą o zmiennym przebiegu, duże znaczenie ma jej ciągła ocena kliniczna i dostosowana do niej modyfikacja leczenia. Niestety, stopień ciężkości nie dopasowuje się elastycznie do odpowiedzi na leczenie. Biorąc ten fakt pod uwagę, światowi eksperci zalecają zmianę w postępowaniu z astmą, przedkładając uzyskanie klinicznej kontroli astmy nad ustaleniem stopnia jej ciężkości, wyróżniając astmę kontrolowaną, częściowo kontrolowaną i niekontrolowaną. Uzyskanie stanu pełnej kontroli astmy formułuje się w raporcie GINA 2006 jako główny cel leczenia. Kontrola astmy odnosi się do stopnia opanowania objawów i byłoby najlepiej, gdyby dotyczyła też markerów zapalenia i patofizjologicznych wykładników choroby. Określenie stopnia kontroli choroby zgodnie z obecnymi założeniami stanowi podstawę wyboru i modyfikacji leczenia – właściwe ustalenie stopnia kontroli astmy wpływa na skuteczność leczenia.

  15. Extension of Ko Straight-Beam Displacement Theory to Deformed Shape Predictions of Slender Curved Structures

    Ko, William L.; Fleischer, Van Tran

    2011-01-01

    The Ko displacement theory originally developed for shape predictions of straight beams is extended to shape predictions of curved beams. The surface strains needed for shape predictions were analytically generated from finite-element nodal stress outputs. With the aid of finite-element displacement outputs, mathematical functional forms for curvature-effect correction terms are established and incorporated into straight-beam deflection equations for shape predictions of both cantilever and two-point supported curved beams. The newly established deflection equations for cantilever curved beams could provide quite accurate shape predictions for different cantilever curved beams, including the quarter-circle cantilever beam. Furthermore, the newly formulated deflection equations for two-point supported curved beams could provide accurate shape predictions for a range of two-point supported curved beams, including the full-circular ring. Accuracy of the newly developed curved-beam deflection equations is validated through shape prediction analysis of curved beams embedded in the windward shallow spherical shell of a generic crew exploration vehicle. A single-point collocation method for optimization of shape predictions is discussed in detail

    Ice algae are the major primary producers in seasonally ice-covered oceans during the cold season. Diurnal change in solar radiation is inevitable for ice algae, even beneath seasonal sea ice in lower-latitude regions. In this work, we focused on the photosynthetic response of ice algae under diurnally changing irradiance in Saroma-ko Lagoon, Japan. Photosynthetic properties were assessed by pulse-amplitude modulation (PAM) fluorometry. The species composition remained almost the same throughout the investigation. The maximum electron transport rate ( rETRmax), which indicates the capacity of photosynthetic electron transport, increased from sunrise until around noon and decreased toward sunset, with no sign of the afternoon depression commonly observed in other photosynthetic organisms. The level of non-photochemical quenching, which indicates photoprotection activity by dissipating excess light energy via thermal processes, changed with diurnal variations in irradiance. The pigment composition appeared constant, except for xanthophyll cycle pigments, which changed irrespective of irradiance. These results indicate that ice algae tune their photosynthetic system harmonically to achieve efficient photosynthesis under diurnally changing irradiance, while avoiding damage to photosystems. This regulation system may be essential for productive photosynthesis in ice algae.

    In the paper, the slope stability problem of the Kościuszko Mound in Cracow, Poland is considered. The slope stability analysis was performed using Plaxis FEM program. The outer surface of the mound has complex geometry. The slope of the cone is not uniform in all directions, on the surface of the cone are pedestrian paths. Due to its complicated geometry it was impossible to do computing by Plaxis input pre-procesor. The initial element mesh was generated using Autodesk Autocad 3D and next it was updated by Plaxis program. The soil parameters were adopted in accordance with the detailed geological soil testing performed in 2012. Calculating model includes geogrids. The upper part was covered by MacMat geogrid, while the lower part of the Mound was reinforced using Terramesh Matt geogrid. The slope analysis was performed by successives reduction of φ /c parameters. The total multiplayer ΣMsf is used to define the value of the soil strength parameters. The article presents the results of slope stability before and after the rainfall during 33 days of precipitation in flood of 2010.

    Full Text Available Proper management is one of key elements of the natural landscape protection strategy. Park-forests with protected and conserved natural elements represent attractive eco-tourism urban zones. Košutnjak is the most visited park-forest in Serbian capitol Belgrade, unfortunately with increasing number of degraded and devastated areas as a consequence of negative human impacts in the past. In order to conserve natural values in this popular forested city area, and to improve its tourism potential, we found that in achieving that goal, it is meaningful to asses possible management practices and identify the most desired one by applying the analytic hierarchy process (AHP, scientifically sound multi-criteria decision making tool. Based on the obtained results, a recommended strategy is to renovate natural vegetation and to promote recreational and tourism offer in Košutnjak with respect of the sustainability principle.

    Transcriptional regulation is a key process in the formation of long-term memories. Che-1 is a protein involved in the regulation of gene transcription that has recently been proved to bind the transcription factor NF-κB, which is known to be involved in many memory-related molecular events. This evidence prompted us to investigate the putative role of Che-1 in memory processes. For this study we newly generated a line of Che-1(+/-) heterozygous mice. Che-1 homozygous KO mouse is lethal during development, but Che-1(+/-) heterozygous mouse is normal in its general anatomical and physiological characteristics. We analyzed the behavioral characteristic and memory performance of Che-1(+/-) mice in two NF-κB dependent types of memory. We found that Che-1(+/-) mice show similar locomotor activity and thigmotactic behavior than wild type (WT) mice in an open field. In a similar way, no differences were found in anxiety-like behavior between Che-1(+/-) and WT mice in an elevated plus maze as well as in fear response in a contextual fear conditioning (CFC) and object exploration in a novel object recognition (NOR) task. No differences were found between WT and Che-1(+/-) mice performance in CFC training and when tested at 24h or 7days after training. Similar performance was found between groups in NOR task, both in training and 24h testing performance. However, we found that object recognition memory persistence at 7days was impaired in Che-1(+/-) heterozygous mice. This is the first evidence showing that Che-1 is involved in memory processes.

    The RF-knockout (RF-KO) slow-extraction method with frequency modulation (FM) and amplitude modulation (AM) has brought high-accuracy irradiation to the treatment of a cancer tumor moving with respiration, because of a quick response to beam start/stop. However, a beam spill extracted from a synchrotron ring through RF-KO slow-extraction has a huge ripple with a frequency of around 1 kHz related to the FM. The spill ripple will disturb the lateral dose distribution in the beam scanning methods. Thus, the source of the spill ripple has been investigated through experiments and simulations. There are two tune regions for the extraction process through the RF-KO method: the extraction region and the diffusion region. The particles in the extraction region can be extracted due to amplitude growth through the transverse RF field, only when its frequency matches with the tune in the extraction region. For a large chromaticity, however, the particles in the extraction region can be extracted through the synchrotron ...

    Noradrenergic signaling, through the α 2A and α 2C adrenergic receptors modulates the cognitive and behavioral symptoms of disorders such as schizophrenia, attention deficit hyperactivity disorder (ADHD), and addiction. However, it is unknown whether the α 2B receptor has any significant role in CNS function. The present study elucidates the potential role of the α 2B receptor in CNS function via the discovery and use of the first subtype-selective α 2B antagonist (AGN-209419), and behavioral analyses of α-receptor knockout (KO) mice. Using AGN-209419 as radioligand, α 2B receptor binding sites were identified within the olfactory bulb, cortex, thalamus, cerebellum, and striatum. Based on the observed expression patterns of α 2 subtypes in the brain, we compared α 2B KO, α 2A KO and α 2C KO mice behavioral phenotypes with their respective wild-type lines in anxiety (plus maze), compulsive (marble burying), and sensorimotor (prepulse inhibition) tasks. α 2B KO mice exhibited increased marble burying and α 2C KO mice exhibited an increased startle response to a pulse stimulus, but otherwise intact prepulse inhibition. To further explore compulsive behavior, we evaluated novelty-induced locomotor hyperactivity and found that α 2B KO and α 2C KO mice exhibited increased locomotion in the open field. Interestingly, when challenged with amphetamine, α 2C KO mice increased activity at lower doses relative to either α 2A KO or WT mice. However, α 2B KO mice exhibited stereotypy at doses of amphetamine that were only locomotor stimulatory to all other genotypes. Following co-administration of AGN-209419 with low-dose amphetamine in WT mice, stereotypy was observed, mimicking the α 2B KO phenotype. These findings suggest that the α 2B receptor is involved in CNS behaviors associated with sensorimotor gating and compulsivity, and may be therapeutically relevant for disorders such as schizophrenia, ADHD, post-traumatic stress disorder, addiction, and

  10. Functional consequences of brain glycogen deficiency on the sleep-wake cycle regulation in PTG-KO mice

    2017-12-31

    Introduction: In the CNS, glycogen is mainly localized in astrocytes where its levels are linked to neuronal activity. Astrocytic glycogen synthesis is regulated by glycogen synthase (GS) activity that is positively controlled by protein targeting to glycogen (PTG) expression levels. Although the role of glycogen in sleep/wake regulation is still poorly understood, we have previously demonstrated that, following a 6 hour gentle sleep deprivation (GSD), PTG mRNA expression and GS activity increased in the brain in mice while glycogen levels were paradoxically maintained and not affected. In order to gain further insight on the role of PTG in this process, we studied the sleep/wake cycle parameters in PTG knockout (PTG-KO) mice under baseline conditions and after a 6 hour GSD. Glycogen levels as well as mRNAs expression of genes related to energy metabolism were also determined in several brain areas. Materials and methods: Adult male C57BL/6J (WT) and PTG-KO mice were sleep-recorded under baseline conditions (24 h recordings, 12 h light/dark cycle) and following 6 hours GSD from ZT00 to ZT06. Vigilance states were visually scored (4 s temporal window). Spectral analysis of the EEG signal was performed using a discrete Fourier transformation. Glycogen measurements and gene expression analysis were assessed using a biochemical assay and quantitative RT-PCR respectively, on separate cohorts in WT vs PTG-KO mice at the end of the 6 hours GSD or in control animals (CTL) in different brain structures. Results: Quantitative analysis of the sleep/wake cycle under baseline conditions did not reveal major differences between the WT and the PTG-KO mice. However, during the dark period, the PTG-KO mice showed a significant increase in the number of wake and slow wave sleep episodes (respectively +26.5±8% and +26.1±8%; p< 0.05) together with a significant shortening in their duration (-21.6±7.2% and -14.3±2.8%; p< 0.01). No such quantitative changes were observed during

    The incidence of AA amyloidosis is high in humans with rheumatoid arthritis and several animal species, including cats and cattle with prolonged inflammation. AA amyloidosis can be experimentally induced in mice using severe inflammatory stimuli and a coinjection of AA amyloid; however, difficulties have been associated with transmitting AA amyloidosis to a different animal species, and this has been attributed to the "species barrier." The interleukin-1 receptor antagonist knockout (IL-1raKO) mouse, a rodent model of human rheumatoid arthritis, has been used in the transmission of AA amyloid. When IL-1raKO and BALB/c mice were intraperitoneally injected with mouse AA amyloid together with a subcutaneous pretreatment of 2% AgNO3, all mice from both strains that were injected with crude or purified murine AA amyloid developed AA amyloidosis. However, the amyloid index, which was determined by the intensity of AA amyloid deposition, was significantly higher in IL-1raKO mice than in BALB/c mice. When IL-1raKO and BALB/c mice were injected with crude or purified bovine AA amyloid together with the pretreatment, 83% (5/6 cases) and 38% (3/8 cases) of IL-1raKO mice and 17% (1/6 cases) and 0% (0/6 cases) of BALB/c mice, respectively, developed AA amyloidosis. Similarly, when IL-1raKO and BALB/c mice were injected with crude or purified feline AA amyloid, 33% (2/6 cases) and 88% (7/8 cases) of IL-1raKO mice and 0% (0/6 cases) and 29% (2/6 cases) of BALB/c mice, respectively, developed AA amyloidosis. These results indicated that IL-1raKO mice are a useful animal model for investigating AA amyloidogenesis. © The Author(s) 2014.

Prompt γ rays were detected with the GRETINA array located in front of the S800 separator. A hodoscope at the S800 focal plane captured the 68Ni ions, where isomeric decays could be correlated with prompt γ rays. Decay of the first excited state, a 0+ isomer, was observed, confirming that its energy substantially differs from the literature value. Comparing the decay patterns of excited states with shell-model calculations provides insight into their underlying structure. Data from 70Zn + 208Pb DI reactions studied with Gammasphere provide results consistent with the 2nKO. Single-particle strengths are also under investigation in the odd- A Ni isotopes via 1nKO reactions.

  18. Beta3 adrenoceptors substitute the role of M(2) muscarinic receptor in coping with cold stress in the heart: evidence from M(2)KO mice.

    We investigated the role of beta3-adrenoceptors (AR) in cold stress (1 or 7 days in cold) in animals lacking main cardioinhibitive receptors-M2 muscarinic receptors (M(2)KO). There was no change in receptor number in the right ventricles. In the left ventricles, there was decrease in binding to all cardiostimulative receptors (beta1-, and beta2-AR) and increase in cardiodepressive receptors (beta3-AR) in unstressed KO in comparison to WT. The cold stress in WT animals resulted in decrease in binding to beta1- and beta2-AR (to 37%/35% after 1 day in cold and to 27%/28% after 7 days in cold) while beta3-AR were increased (to 216% of control) when 7 days cold was applied. MR were reduced to 46% and 58%, respectively. Gene expression of M2 MR in WT was not changed due to stress, while M3 was changed. The reaction of beta1- and beta2-AR (binding) to cold was similar in KO and WT animals, and beta3-AR in stressed KO animals did not change. Adenylyl cyclase activity was affected by beta3-agonist CL316243 in cold stressed WT animals but CL316243 had almost no effects on adenylyl cyclase activity in stressed KO. Nitric oxide activity (NOS) was not affected by BRL37344 (beta3-agonist) both in WT and KO animals. Similarly, the stress had no effects on NOS activity in WT animals and in KO animals. We conclude that the function of M2 MR is substituted by beta3-AR and that these effects are mediated via adenylyl cyclase rather than NOS.

  19. Both chronic treatments by epothilone D and fluoxetine increase the short-term memory and differentially alter the mood status of STOP/MAP6 KO mice.

    Recent evidence underlines the crucial role of neuronal cytoskeleton in the pathophysiology of psychiatric diseases. In this line, the deletion of STOP/MAP6 (Stable Tubule Only Polypeptide), a microtubule-stabilizing protein, triggers various neurotransmission and behavioral defects, suggesting that STOP knockout (KO) mice could be a relevant experimental model for schizoaffective symptoms. To establish the predictive validity of such a mouse line, in which the brain serotonergic tone is dramatically imbalanced, the effects of a chronic fluoxetine treatment on the mood status of STOP KO mice were characterized. Moreover, we determined the impact, on mood, of a chronic treatment by epothilone D, a taxol-like microtubule-stabilizing compound that has previously been shown to improve the synaptic plasticity deficits of STOP KO mice. We demonstrated that chronic fluoxetine was either antidepressive and anxiolytic, or pro-depressive and anxiogenic, depending on the paradigm used to test treated mutant mice. Furthermore, control-treated STOP KO mice exhibited paradoxical behaviors, compared with their clear-cut basal mood status. Paradoxical fluoxetine effects and control-treated STOP KO behaviors could be because of their hyper-reactivity to acute and chronic stress. Interestingly, both epothilone D and fluoxetine chronic treatments improved the short-term memory of STOP KO mice. Such treatments did not affect the serotonin and norepinephrine transporter densities in cerebral areas of mice. Altogether, these data demonstrated that STOP KO mice could represent a useful model to study the relationship between cytoskeleton, mood, and stress, and to test innovative mood treatments, such as microtubule-stabilizing compounds. © 2012 The Authors Journal of Neurochemistry © 2012 International Society for Neurochemistry.

    A simple, green and efficient extraction method named modified-solvent free microwave extraction (M-SFME) was employed for the extraction of essential oils (EOs) from Amomun tsao-ko. The process of M-SFME was optimized with the prominent preponderance of such higher extraction yield (1.13%) than those of solvent free microwave extraction (SFME, 0.91%) and hydrodistillation (HD, 0.84%) under the optimal parameters. Thirty-four volatile substances representing 95.4% were identified. The IC 50 values of EOs determined by DPPH radical scavenging activity and β-carotene/linoleic acid bleaching assay were 5.27 and 0.63mg/ml. Furthermore, the EOs exhibited moderate to potent broad-spectrum antimicrobial activity against all tested strains including five gram-positive and two gram-negative bacteria (MIC: 2.94-5.86mg/ml). In general, M-SFME is a potential and desirable alternative for the extraction of EOs from aromatic herbs, and the EOs obtained from A. tsao-ko can be explored as a potent natural antimicrobial and antioxidant preservative ingredient in food industry from the technological and economical points of view.

    During the load-following operation of nuclear power plants, flow rate, temperature, and pressure in the piping system can be varied by changing the electric power output level, and these variations can cause different vibration phenomena in the piping system. The piping system vibration is important because it is directly related to the dynamic stress of the piping system and can affect the life of the piping system through structural fatigue. An assessment of vibration levels for the classes II and III piping systems of the Ko-Ri Unit 4950-MW nuclear power plant was performed according to the given pattern of the load-following operation to study its feasibility from the viewpoint of piping system vibration. The classes II and III piping system vibration of the Ko-Ri Unit 4 may not cause any potential problem under the given pattern of the load-following operation; however, it is recommended that long-term operation in the 85 to 95% power range be avoided as much as possible

    Full Text Available Fragile X syndrome (FXS is the most common form of inherited intellectual disability and the leading known genetic cause of autism. Fragile X mental retardation protein (FMRP, which is absent or expressed at substantially reduced levels in FXS, binds to and controls the postsynaptic translation of amyloid β-protein precursor (AβPP mRNA. Cleavage of AβPP can produce β-amyloid (Aβ, a 39-43 amino acid peptide mis-expressed in Alzheimer's disease (AD and Down syndrome (DS. Aβ is over-expressed in the brain of Fmr1(KO mice, suggesting a pathogenic role in FXS. To determine if genetic reduction of AβPP/Aβ rescues characteristic FXS phenotypes, we assessed audiogenic seizures (AGS, anxiety, the ratio of mature versus immature dendritic spines and metabotropic glutamate receptor (mGluR-mediated long-term depression (LTD in Fmr1(KO mice after removal of one App allele. All of these phenotypes were partially or completely reverted to normal. Plasma Aβ(1-42 was significantly reduced in full-mutation FXS males compared to age-matched controls while cortical and hippocampal levels were somewhat increased, suggesting that Aβ is sequestered in the brain. Evolving therapies directed at reducing Aβ in AD may be applicable to FXS and Aβ may serve as a plasma-based biomarker to facilitate disease diagnosis or assess therapeutic efficacy.

    This study evaluates the Musical Concentration Training with Pepe ("MusiKo mit Pepe") for children aged 5 to 10 years with attention deficits. Using a pre-post-control design (N = 108), changes in attention capacity are measured by the Test of Attentional Performance for Children (KiTAP), whereas changes in the quality of life are assessed with the Children's Questionnaire (KINDL-R). Additionally, we utilized the Symptom Checklist for Attention Deficit Hyperactivity Disorders (FBB-ADHS) and for Conduct Disorder (FBB-SSV) of the Diagnostic System of Mental Disorders in Children and Adolescents II based on ICD-10 and DSM-IV as well as the Child Behavior Checklist and the Teacher's Report Form (CBCL, TRF). Significant pre-post effects were found in both attention and quality of life for children treated by the training compared to controls. Moreover, significant reductions were detected in ADHD symptomatology in parents' and teachers' ratings, and in internal problems in parents' ratings. The effectiveness of the intervention was not affected by age, sex, intelligence, or migration background. The music-based training "MusiKo mit Pepe" is an effective intervention for children with attention deficits, pending replication of these findings in future studies.

    Pandemic outbreaks of influenza type A viruses have resulted in numerous fatalities around the globe. Since the conventional influenza vaccines (CIV) provide less than 20% protection for individuals with weak immune system, it has been considered that broadly cross-neutralizing antibodies may provide a better protection. Herein, we showed that a recently generated humanized mouse (DRAGA mouse; HLA-A2. HLA-DR4. Rag1KO. IL-2Rgc KO. NOD) that lacks the murine immune system and expresses a functional human immune system can be used to generate cross-reactive, human anti-influenza monoclonal antibodies (hu-mAb). DRAGA mouse was also found to be suitable for influenza virus infection, as it can clear a sub-lethal infection and sustain a lethal infection with PR8/A/34 influenza virus. The hu-mAbs were designed for targeting a human B-cell epitope ( 180 WGIHHPPNSKEQ QNLY 195 ) of hemagglutinin (HA) envelope protein of PR8/A/34 (H1N1) virus with high homology among seven influenza type A viruses. A single administration of HA 180-195 specific hu-mAb in PR8-infected DRAGA mice significantly delayed the lethality by reducing the lung damage. The results demonstrated that DRAGA mouse is a suitable tool to (i) generate heterotype cross-reactive, anti-influenza human monoclonal antibodies, (ii) serve as a humanized mouse model for influenza infection, and (iii) assess the efficacy of anti-influenza antibody-based therapeutics for human use.

    Full Text Available The Rag2 knockout (KO mouse is a well-established immune-compromised animal model for biomedical research. A comparative study identified the deregulated expression of microRNAs (miRNAs and messenger RNAs (mRNAs in Rag2 KO mice. However, the interaction between deregulated genes and miRNAs in the alteration of systemic (cardiac, renal, hepatic, nervous, and hematopoietic regulations and the synthesis of biomolecules (such as l-tryptophan, serotonin, melatonin, dopamine, alcohol, noradrenaline, putrescine, and acetate are unclear. In this study, we analyzed both miRNA and mRNA expression microarray data from Rag2 KO and wild type mice to investigate the possible role of miRNAs in systemic regulation and biomolecule synthesis. A notable finding obtained from this analysis is that the upregulation of several genes which are target molecules of the downregulated miRNAs in Rag2 KO mice, can potentially trigger the degradation of l-tryptophan, thereby leading to the systemic impairment and alteration of biomolecules synthesis as well as changes in behavioral patterns (such as stress and fear responses, and social recognition memory in Rag2 gene-depleted mice. These findings were either not observed or not explicitly described in other published Rag2 KO transcriptome analyses. In conclusion, we have provided an indication of miRNA-dependent regulations of clinical and pathological conditions in cardiac, renal, hepatic, nervous, and hematopoietic systems in Rag2 KO mice. These results may significantly contribute to the prediction of clinical disease caused by Rag2 deficiency.

    We report on the first case of human babesiosis in Korea. The intraerythrocytic parasite (KO1) in the patient's blood mainly appeared as paired pyriforms and ring forms; but Maltese cross forms were not seen, and the parasite showed morphological features consistent with those of the genus Babesia sensu stricto. The sequence of the 18S rRNA gene of KO1 was closely related to that of Babesia spp. isolated from sheep in China (similarity, 98%). The present study provides the first evidence of the presence of a hitherto unidentified, new type of Babesia parasite capable of infecting humans.

    Full Text Available Bifosfoniany należą do silnych inhibitorów osteoklastów. Znajdują szerokie zastosowanie w leczeniu chorób przebiegających ze wzmożoną resorpcją kości: osteoporozy, choroby Pageta i osteogenesis imperfecta. Leki te zmniejszają adhezję komórek nowotworowych do kości, ograniczają osteolizę wywołaną nowotworem i hiper‑ kalcemię. Zmniejszają dolegliwości bólowe w szpiczaku mnogim i w przerzutach do kości. Powszechnie panu‑ jące przekonanie o bezpieczeństwie spowodowało rozszerzenie wskazań do ich stosowania. Pacjenci onkolo‑ giczni przyjmujący bifosfoniany dożylnie, w wysokich dawkach są bardziej narażeni na działania niepożądane terapii niż pacjenci przyjmujący je doustnie. Jednym z najpoważniejszych powikłań jest martwica kości szczęk. W 2003 roku opisano po raz pierwszy związek pomiędzy terapią bifosfonianami a martwicą kości szczęk. W piśmiennictwie znajdujemy coraz więcej przykładów tego działania niepożądanego, także po stosowaniu leków doustnie. Mogą pojawiać się ból, obrzęk, owrzodzenie, odsłonięcie kości, przetoki, złamania patologiczne, uciążliwe dla pacjenta i obniżające jakość życia. Leczenie martwicy kości szczęk jest trudne i rzadko przynosi spodziewany efekt. Główną rolę odgrywa leczenie zachowawcze i redukcja objawów. Odstawienie bifosfonia‑ nów nie ma bezpośredniego wpływu na przebieg martwicy kości szczęk, ze względu na kumulację leku w kości. Istotne jest przygotowanie pacjenta przed rozpoczęciem podawania bifosfonianów, wymagające stałej współ‑ pracy pomiędzy lekarzami onkologami, ortopedami i chirurgami szczękowo-twarzowymi. Higiena jamy ustnej i leczenie chorób współistniejących stanowi ważny element postępowania. Celem pracy jest przedstawienie trzech przypadków martwicy kości szczęk u pacjentów poddanych leczeniu bifosfonianami.

  17. Transport systems of Ventricaria ventricosa: I/V analysis of both membranes in series as a function of [K(+)](o).

    Science.gov (United States)

    Beilby, M J; Bisson, M A

    1999-09-01

    The current-voltage (I/V) profiles of Ventricaria (formerly Valonia) membranes were measured at a range of external potassium concentrations, [K(+)](o), from 0.1 to 100 mm. The conductance-voltage (G/V) characteristics were computed to facilitate better resolution of the profile change with time after exposure to different [K(+)](o). The resistance-voltage (R/V) characteristics were computed to attempt resolution of plasmalemma and tonoplast. Four basic electrophysiological stages emerged: (1) Uniform low resistance between -60 and +60 mV after the cell impalement. (2) High resistance between +50 and +150 for [K(+)](o) from 0.1 to 1.0 mm and hypotonic media. (3) High resistance between -150 and -20 mV for [K(+)](o) of 10 mm (close to natural seawater) and hypertonic media. (4) High resistance between -150 and +170 mV at [K(+)](o) of 100 mm. The changes between these states were slow, requiring minutes to hours and sometimes exhibiting spontaneous oscillations of the membrane p.d. (potential difference). Our analysis of the I/V data supports a previous hypothesis, that Ventricaria tonoplast is the more resistive membrane containing a pump, which transports K(+) into the vacuole to regulate turgor. We associate state (1) with the plasmalemma conductance being dominant and the K(+) pump at the tonoplast short-circuited probably by a K(+) channel, state (2) with the K(+) pump "off" or short-circuited at p.d.s more negative than +50 mV, state (3) with the K(+) pump "on, " and state (4) with the pump dominant, but affected by high K(+). A model for the Ventricaria membrane system is proposed.

When mineral springs were not able to cover the consumption of the mineral waters in 1870 a well resulting in nowadays unique „ Herľany geyser“ was drilled by Viliam Zsigmondy. In the second half of the 20th century a geological prospecting on oil and natural gas realised in the Košice basin and East Slovakian Neogene basin was. Based on the results, of prospecting structural boreholes, aimed at hydrocarbon prospection, geophysical inestigation and hydrogeological investigation a geothermal potential of this part of the area was confirmed. The geothermal boreholes (GTD-1, GTD-2 and GTD-3 were drilled after 30 years after it. The results from these wells were very positive because the discharge reached 150 litres per second and the temperature of water was 126 °C on the borehole mouth.The time flies and the heasty attested geothermal source in the meantime isn´t utilized enough. The history as well as the today story is known but the perspective of this spring in the future is not clear. Possibilities of its exploitation as an alternative energy source are great but a grand investor is needed. Maybe, the EU-founds will be the only objective future for a prosperity of our followers.

    Full Text Available Kyung-Ok-Ko (KOK, a well-known traditional Korean medicinal formula, has long been used to invigorate the essential qi. This use of KOK may be associated with reproductive ability as a more modern concept. The protective effect of KOK was evaluated against deterioration of testicular function induced by heat exposure in male mice. Male fertility was disrupted by scrotal heat stress at 43°C for 5 weeks. KOK (0.25, 0.50, and 2.00 g/kg/day was administered orally at 3 h after the stress. To evaluate the protective effect of KOK, body weight, testicular weight, sperm count, sperm motility, and histopathological changes in the testes were evaluated. KOK-treated mice significantly recovered their general health, as evidenced by body weight. KOK-treated mice also showed significantly higher testes weights, sperm counts, and sperm motility than did the heat stress group. KOK-treated mice significantly recovered the morphological appearance of the seminiferous tubules and seminiferous epithelium. Furthermore, KOK-treated mice significantly increased antioxidant enzyme activities and reduced the protein expressions of apoptosis in the testes. KOK significantly protects against heat-induced damage to testicular function in male mice by inhibiting oxidative stress and apoptosis, indicating that KOK may be an effective agent for treatment of heat-induced male infertility.

    Small towns in the Lublin Province are abundant with buildings possessed of outstanding historical and architectural values, representing the culture of past generations. Piaski, about 30 km east of Lublin, also boasts some of the remarkable characteristic of small towns. Not only does it feature post-Jewish tenements, but also a palace and complexes of religious buildings situated on its outskirts. This article focuses on the Kościelec - an unused, dilapidated former Protestant church. Now, works are being carried out that have inspired the Piaski town authorities to try to find a best-use scenario for the former church, in order to preserve its architectural values for future generations. The authors of this article aim to prove the necessity of research and analysis in finding the best new functions for properties whose function has already been imposed. The example of successfully completed revitalisation works at the palace and park complex in Gardzienice, located not far from the baroque Protestant church in Piaski, illustrates the advantages of some of the adaptation processes that can be employed in such buildings.

  2. Differential Impact of miR-21 on Pain and Associated Affective and Cognitive Behavior after Spared Nerve Injury in B7-H1 ko Mouse

    Full Text Available MicroRNAs (miRNAs are increasingly recognized as regulators of immune and neuronal gene expression and are potential master switches in neuropathic pain pathophysiology. miR-21 is a promising candidate that may link the immune and the pain system. To investigate the pathophysiological role of miR-21 in neuropathic pain, we assessed mice deficient of B7 homolog 1 (B7-H1, a major inhibitor of inflammatory responses. In previous studies, an upregulation of miR-21 had been shown in mouse lymphocytes. Young (8 weeks, middle-aged (6 months, and old (12 months B7-H1 ko mice and wildtype littermates (WT received a spared nerve injury (SNI. We assessed thermal withdrawal latencies and mechanical withdrawal thresholds. Further, we performed tests for anxiety-like and cognitive behavior. Quantitative real time PCR was used to determine miR-21 relative expression in peripheral nerves, and dorsal root ganglia (DRG at distinct time points after SNI. We found mechanical hyposensitivity with increasing age of naïve B7-H1 ko mice. Young and middle-aged B7-H1 ko mice were more sensitive to mechanical stimuli compared to WT mice (young: p < 0.01, middle-aged: p < 0.05. Both genotypes developed mechanical and heat hypersensitivity (p < 0.05 after SNI, without intergroup differences. No relevant differences were found after SNI in three tests for anxiety like behavior in B7-H1 ko and WT mice. Also, SNI had no effect on cognition. B7-H1 ko and WT mice showed a higher miR-21 expression (p < 0.05 and invasion of macrophages and T cells in the injured nerve 7 days after SNI without intergroup differences. Our study reveals that increased miR-21 expression in peripheral nerves after SNI is associated with reduced mechanical and heat withdrawal thresholds. These results point to a role of miR-21 in the pathophysiology of neuropathic pain, while affective behavior and cognition seem to be spared. Contrary to expectations, B7-H1 ko mice did not show higher miR-21

    Full Text Available Insufficient advances in the development of effective therapeutic treatments of sporadic Alzheimer's Disease (sAD to date are largely due to the lack of sAD-relevant animal models. While the vast majority of models do recapitulate AD's hallmarks of plaques and tangles by virtue of tau and/or beta amyloid overexpression, these models do not reflect the fact that in sAD (unlike familial AD these genes are not risk factors per se and that other mechanisms like oxidative stress, metabolic dysregulation and inflammation play key roles in AD etiology.

    Insufficient advances in the development of effective therapeutic treatments of sporadic Alzheimer's Disease (sAD) to date are largely due to the lack of sAD-relevant animal models. While the vast majority of models do recapitulate AD's hallmarks of plaques and tangles by virtue of tau and/or beta amyloid overexpression, these models do not reflect the fact that in sAD (unlike familial AD) these genes are not risk factors per se and that other mechanisms like oxidative stress, metabolic dysregulation and inflammation play key roles in AD etiology. Here we characterize and propose the Fus1 KO mice that lack a mitochondrial protein Fus1/Tusc2 as a new sAD model. To establish sAD relevance, we assessed sAD related deficits in Fus1 KO and WT adult mice of 4-5 months old, the equivalent human age when the earliest cognitive and olfactory sAD symptoms arise. Fus1 KO mice showed oxidative stress (increased levels of ROS, decreased levels of PRDX1), disruption of metabolic homeostasis (decreased levels of ACC2, increased phosphorylation of AMPK), autophagy (decreased levels of LC3-II), PKC (decreased levels of RACK1) and calcium signaling (decreased levels of Calb2) in the olfactory bulb and/or hippocampus. Mice were behaviorally tested using objective and accurate video tracking (Noldus), in which Fus1 KO mice showed clear deficits in olfactory memory (decreased habituation/cross-habituation in the short and long term), olfactory guided navigation memory (inability to reduce their latency to find the hidden cookie), spatial memory (learning impairments on finding the platform in the Morris water maze) and showed more sleep time during the diurnal cycle.

    A critical examination is made of some recent calculations by Ko and Chuang. They seek to show that original work by ourselves, and others, concerning the behavior of light propagating through differentially moving media is in error and that the fundamental structure of the results is, in fact, very different from the results we obtained: not excluding reversal of sign of some of the effects. We demonstrate that the results reported by Ko and Chuang are a consequence of two basic kinds of errors in their analysis. The first, and paramount, error is their use of fundamental basic kinds of errors in their analysis. The first, and paramount error is their use of fundamental relations in physics (such as the Kramers-Kronig dispersion relation) without due regard being given to the conditons imposed in arriving at the basic relationship in the first place, and thier use of particular relationships far outside their domains of validity as though they still held true.The second basic error is in a particular form of the refractive index, n, that Ko and Chuang use to illustrate their general points (which already suffer from the first basic error). The particular refractive index they use has the following unsatisfactory features: (i) it contains unstable modes in the upper half complex frequency plane: contrary to the conventional Kramers-Kronig relationship they invoke as a general principle; (ii) n 2 0 [n 2 (ω)-1]dω=0; (iii) the imaginary part of the dielectric positive (corresponding to absorption), yet the real part contains unstable modes, and the whole of the complex dielectric constant is nonanalytic in the upper half complex frequency plane; (iv) the form of n given by Ko and Chuang is purported to represent a warm, isotropic, Maxwellian plasma which is well known to be absolutely stable, so that no unstable modes can exist

    The main components of the plasma facing components (PFCs) in the tokamak are the blanket first wall and divertor, which include the armour materials, the heat sink with the cooling mechanism, and the diagnostics devices for the temperature measurement. The Korea Heat Load Test facility by using electron beam (KoHLT-EB) has been operating for the plasma facing components to develop fusion engineering. This electron beam facility was constructed using a 300 kW electron gun and a cylindrical vacuum chamber. Performance tests were carried out for the calorimetric calibrations with Cu dummy mockup and for the heat load test of large Cu module. For the simulation of the heat load test of each mockup, the preliminary thermal-hydraulic analyses with ANSYS-CFX were performed. For the development of the plasma facing components in the fusion reactors, test mockups were fabricated and tested in the high heat flux test facility. To perform a beam profile test, an assessment of the possibility of electron beam Gaussian power density profile and the results of the absorbed power for that profile before the test starts are needed. To assess the possibility of a Gaussian profile, for the qualification test of the Gaussian heat load profile, a calorimeter mockup and large Cu module were manufactured to simulate real heat. For this high-heat flux test, the Korean high-heat flux test facility using an electron beam system was constructed. In this facility, a cyclic heat flux test will be performed to measure the surface heat flux, surface temperature profile, and cooling capacity

    Full Text Available Kyung-Ok-Ko (KOK, a traditional herbal prescription composed of Rehmannia glutinosa Liboschitz var. purpurae, Lycium chinense, Aquillaria agallocha, Poria cocos, Panax ginseng, and honey, has been widely used in traditional Oriental medicine as a vitalizing medicine or as the prescription for patients with age-associated disorders such as amnesia and stroke. However, the potential protective value of KOK for the treatment of polycystic ovarian syndrome (PCOS is largely unknown. We investigated whether pre-administration (daily from 2 hours before PCOS induction and post-administration (daily after induction of PCOS of KOK (0.5, 1.0, and 2.0 g/kg/day, p.o. could have a protective effect in a dehydroepiandrosterone (DHEA, s.c.-induced PCOS rat model. Pre-administration of KOK significantly decreased the elevated body weight and ovary weight, elevated size and number of follicular cysts, elevated level of serum glucose, and estradiol after DHEA injection. KOK reduced the elevated percentage of CD8 (+ T lymphocytes in lymph nodes, the elevated mRNA expression of CD11b and CD3 in ovaries, and infiltration of macrophages in ovarian tissue with PCOS. KOK diminished the increased mRNA expression of pro-inflammatory cytokines (IL-1β, IL-6, TNF-α, chemokines (IL-8, MCP-1, and iNOS in the ovaries, and increased the reduced mRNA expression of growth factors (EGF, TGF-β by DHEA injection. Post-administration of KOK also improved the DHEA-induced PCOS-like symptoms, generally similar to those evident from pre-administration of KOK. KOK may effectively prevent and improve DHEA-induced PCOS via anti-inflammatory action, indicating its preventive and therapeutic potential for suppressing PCOS.

    While titanium oxide is excited by the light, electrons of titanium oxide are taken away by the light energy to form positive holes. Water will be decomposed into hydrogen ion and hydroxy radical (OH) by these positive holes. This hydroxy radical is a strong reactive substance called active oxygen, it decomposes organisms. Besides this photo- catalyst function, the titanium oxide can also make surface of a substance superhydrophilic. The super hydrophilicity results in not forming water drops on the glass surface but spreading all over the surface to prevent a covering of fog on the glass surface. The published patents concerning the photo catalysts were 593 from Jan. 1998 to Jan. 1999. The applicant order is the first TOTO 143, the second Daikin Industry 19, the third Toshiba Raitech, Nitto Denko, Hitachi 17 respectively. (NEDO)

    Amomum tsao-ko Crevost et Lemaire, used as a spice in Asia, is an important source of Chinese cuisine and traditional Chinese medicines. A. tsao-ko is reported to exert a variety of biological and pharmacological activities, including anti-proliferative, anti-oxidative and neuroprotective effects. In this study, NNMBS227, consisting of the ethanol extract of A. tsao-ko, exhibited potent anti-inflammatory activities in RAW264.7 macrophages. We investigated the effect of NNMBS227 in the suppression of pro-inflammatory mediators, including pro-inflammatory enzymes (inducible nitric oxide synthase and cyclooxygenase-2) and cytokines (tumor necrosis factor-α and interleukin-1β) in LPS stimulated macrophages. NNMBS227 also inhibited the phosphorylation and degradation of IκB-α, as well as the nuclear translocation of nuclear factor kappa B (NF-κB) p65 caused by stimulation with LPS. In addition, NNMBS227 induced heme oxygenase (HO)-1 expression through the nuclear translocation of nuclear factor E2-related factor 2 (Nrf2) in macrophages. Using tin protoporphyrin (SnPP), an HO activity inhibitor, we confirmed an association between the anti-inflammatory effects of NNMBS227 and the up-regulation of HO-1. These findings suggest that Nrf2-dependent increases in the expression of HO-1 induced by NNMBS227 conferred anti-inflammatory activities in LPS stimulated RAW264.7 macrophages.

    The Keanakākoʻi Tephra at Kīlauea Volcano has previously been interpreted by some as the product of a caldera-forming eruption in 1790 CE. Our study, however, finds stratigraphic and 14C evidence that the tephra instead results from numerous eruptions throughout a 300-year period between about 1500 and 1800. The stratigraphic evidence includes: (1) as many as six pure lithic ash beds interleaved in sand dunes made of earlier Keanakākoʻi vitric ash, (2) three lava flows from Kīlauea and Mauna Loa interbedded with the tephra, (3) buried syneruptive cultural structures, (4) numerous intraformational water-cut gullies, and (5) abundant organic layers rich in charcoal within the tephra section. Interpretation of 97 new accelerator mass spectrometry (AMS) 14C ages and 4 previous conventional ages suggests that explosive eruptions began in 1470–1510 CE, and that explosive activity continued episodically until the early 1800s, probably with two periods of quiescence lasting several decades. Kīlauea's caldera, rather than forming in 1790, predates the first eruption of the Keanakākoʻi and collapsed in 1470–1510, immediately following, and perhaps causing, the end of the 60-year-long, 4–6 km3 ʻAilāʻau eruption from the east side of Kīlauea's summit area. The caldera was several hundred meters deep when the Keanakākoʻi began erupting, consistent with oral tradition, and probably had a volume of 4–6 km3. The caldera formed by collapse, but no eruption of lava coincided with its formation. A large volume of magma may have quickly drained from the summit reservoir and intruded into the east rift zone, perhaps in response to a major south-flank slip event, leading to summit collapse. Alternatively, magma may have slowly drained from the reservoir during the prolonged ʻAilāʻau eruption, causing episodic collapses before the final, largest downdrop took place. Two prolonged periods of episodic explosive eruptions are known at Kīlauea, the Keanakāko

    Cyclophilin B (CyPB), encoded by PPIB, is an ER-resident peptidyl-prolyl cis-trans isomerase (PPIase) that functions independently and as a component of the collagen prolyl 3-hydroxylation complex. CyPB is proposed to be the major PPIase catalyzing the rate-limiting step in collagen folding. Mutations in PPIB cause recessively inherited osteogenesis imperfecta type IX, a moderately severe to lethal bone dysplasia. To investigate the role of CyPB in collagen folding and post-translational modifications, we generated Ppib−/− mice that recapitulate the OI phenotype. Knock-out (KO) mice are small, with reduced femoral areal bone mineral density (aBMD), bone volume per total volume (BV/TV) and mechanical properties, as well as increased femoral brittleness. Ppib transcripts are absent in skin, fibroblasts, femora and calvarial osteoblasts, and CyPB is absent from KO osteoblasts and fibroblasts on western blots. Only residual (2–11%) collagen prolyl 3-hydroxylation is detectable in KO cells and tissues. Collagen folds more slowly in the absence of CyPB, supporting its rate-limiting role in folding. However, treatment of KO cells with cyclosporine A causes further delay in folding, indicating the potential existence of another collagen PPIase. We confirmed and extended the reported role of CyPB in supporting collagen lysyl hydroxylase (LH1) activity. Ppib−/− fibroblast and osteoblast collagen has normal total lysyl hydroxylation, while increased collagen diglycosylation is observed. Liquid chromatography/mass spectrometry (LC/MS) analysis of bone and osteoblast type I collagen revealed site-specific alterations of helical lysine hydroxylation, in particular, significantly reduced hydroxylation of helical crosslinking residue K87. Consequently, underhydroxylated forms of di- and trivalent crosslinks are strikingly increased in KO bone, leading to increased total crosslinks and decreased helical hydroxylysine- to lysine-derived crosslink ratios.

    Kyung-Ok-Ko (KOK), a traditional herbal prescription, contains six main ingredients; Rehmannia glutinosa var. purpurae, Lycium chinense, Aquillaria agallocha, Poria cocos, Panax ginseng, and honey. KOK has been widely taken as a traditional oriental medicine for improving blood circulation or age-related symptoms, such as dementia and stroke. However, the effect of KOK on platelet activity has not been clarified. To evaluate the effect of KOK on platelet function, we evaluated its effect on functional markers of platelet activation such as aggregation and shape change. As a mechanism study for the effect of KOK, we examined its effect on granule secretion, intracellular Ca(2+) increase, and PLCγ and Akt activation. To investigate the effect of orally administered KOK (0.5, 1, 2 g/kg), we examined its ex vivo effect on platelet aggregation in rat, and its in vivo anti-thrombotic effect in mice thromboembolism model. Furthermore, the effect of KOK on bleeding time was examined to estimate its potential side effect. KOK (0.3, 1, 3, 10 mg/ml) inhibited collagen-induced platelet aggregation and shape change in rat platelets in a concentration-dependent manner. The mechanism for the anti-platelet effect of KOK seems to involve the inhibition of ATP release, intracellular Ca(2+) elevation, and the phosphorylation of PLCγ and Akt. In rat ex vivo study, KOK (2 g/kg, p.o. for 1 day, and 0.5, 1, 2 g/kg, p.o. for 7 days) also had significant inhibitory effects on collagen-induced platelet aggregation. In addition, KOK showed a significant protective effect against thrombosis attack in mice. The prolongation of bleeding time by KOK was much less than that by ASA, suggesting a beneficial potential of KOK than ASA in view of side effect. These findings suggest that KOK elicits remarkable anti-platelet and anti-thrombotic effects with less side effect of bleeding, and therefore, it may have a therapeutic potential for the prevention of platelet-associated cardiovascular diseases

The prospective study was conducted to evaluate the effect of dietary antioxidants on COPD risk and lung function in the Korean population.Methods: The data were collected from the community-based Korean Genome Epidemiology Study (KoGES cohort. To diagnose COPD, forced expiratory volume (FEV1 and forced vital capacity (FVC were measured by spirometry. The dietary intake of antioxidant vitamins was estimated from validated Food-Frequency Questionnaire. For the analysis, 325 COPD patients and 6,781 at risk subjects were selected from the cohort of 10,038 subjects. Multiple logistic regression models were used to examine the odds ratio (OR after adjusting for age, sex, marital status, income, history of asthma, history of tuberculosis, and smoking.Results: The risk of COPD was positively associated with aging, low education, low household income, lower body mass index, and cigarette smoking. The risk of COPD decreased with increase in the dietary vitamin C (ORQ1 vs Q5=0.66, Ptrend=0.03 and vitamin E (ORQ1 vs Q5=0.56, Ptrend=0.05 intake, predominantly, in men (Ptrend=0.01 and 0.05 for vitamins C and E, respectively. In addition, the lung function was significantly improved with increase in vitamins C (FEV1, P=0.04; FVC, P=0.03 and E (FEV1, P=0.03; FVC, P=0.04 intake. No statistically significant interactions were observed between smoking and vitamin C or E intake in relation to COPD risk among men.Conclusion: Our results suggest the independent beneficial effect of antioxidants, particularly

    The collocated station Košetice - Křešín u Pacova, central Czech Republic, is a major research and monitoring infrastructure in the Czech Republic and central Europe. It consists of two basic components: the observatory Košetice run since 1988 by the Czech Hydrometeorological Institute and the atmospheric station (AS) Křešín u Pacova starting operation in 2013. The AS is built and run by CzechGlobe - Global Change Research Centre, Academy of Sciences of the Czech Republic and is situated 100 m far from the observatory. There are three research and monitoring activities at the collocated station providing data necessary for the research on climate and related changes. The AS Křešín u Pacova consists of a 250 m tall tower serving for ground-based and vertical gradient measurements of (i) concentrations of CO2, CO, CH4, total gaseous mercury and tropospheric ozone (continuously), (ii) elemental and organic carbon (semicontinuously), (iii) carbon and oxygen isotopes, radon, N2O, SF6 and other species (episodically), (iv) optical properties of atmospheric aerosols and (v) meteorological parameters and the boundary layer height. Further, eddy covariance measurements in the nearby agroecosystem provide data on CO2 and H2O fluxes between the atmosphere and the ecosystem. Finally, monitoring activities at the nearby small hydrological catchment Anenské povodí run under the GEOMON network enables studying local hydrological and biogeochemical cycles. These measurements are supported by the long-term monitoring of meteorological and air quality parameters at the observatory Košetice, that are representative for the central European background. The collocated station provides a big research opportunity and challenge due to (i) a broad spectra of monitored chemical species, meteorological, hydrological and other parameters, (ii) measurements in various environmental compartments and especially the atmosphere, (iii) provision of data suitable for conducting

    We revisit the sensitivity study of the Tokai-to-Kamioka-and-Korea (T2KK) and Tokai-to-Kamioka-and-Oki (T2KO) proposals where a water Cerenkov detector with the 100 kton fiducial volume is placed in Korea (L = 1000 km) and Oki island (L = 653 km) in Japan, respectively, in addition to the Super-Kamiokande for determination of the neutrino mass hierarchy and leptonic CP phase (δ{sub CP}). We systematically study the running ratio of the ν{sub μ} and anti ν{sub μ} focusing beams with dedicated background estimation for the ν{sub e} appearance and ν{sub μ} disappearance signals, especially improving treatment of the neutral-current π{sup 0} backgrounds. Using a ν{sub μ}- anti ν{sub μ} beam ratio between 3:2 and 2.5:2.5 (in units of 10{sup 21}POT with the proton energy of 40 GeV), the mass-hierarchy determination with the median sensitivity of 3-5 σ by the T2KK and 1-4 σ by the T2KO experiment are expected when sin{sup 2}θ{sub 23} = 0.5, depending on the mass-hierarchy pattern and CP phase. These sensitivities are enhanced (reduced) by 30-40% in Δχ{sup 2} when sin{sup 2}θ{sub 23} = 0.6 (0.4). The CP phase is measured with the uncertainty of 20 {sup circle} -50 {sup circle} by the T2KK and T2KO using the ν{sub μ}- anti ν{sub μ} focusing beam ratio between 3.5:1.5 and 1.5:3.5. These findings indicate that inclusion of the anti ν{sub μ} focusing beam improves the sensitivities of the T2KK and T2KO experiments to both the mass-hierarchy determination and the leptonic CP phase measurement simultaneously with the preferred beam ratio being between 3:2-2.5:2.5 (x 10{sup 21}POT).

    Recessive ALS2 mutations are linked to three related but slightly different neurodegenerative disorders: amyotrophic lateral sclerosis, hereditary spastic paraplegia and primary lateral sclerosis. To investigate the function of the ALS2 encoded protein, we generated Als2 knock-out (KO) mice and zAls2 knock-down zebrafish. The Als2(-/-) mice lacking exon 2 and part of exon 3 developed mild signs of neurodegeneration compatible with axonal transport deficiency. In contrast, zAls2 knock-down zebrafish had severe developmental abnormalities, swimming deficits and motor neuron perturbation. We identified, by RT-PCR, northern and western blotting novel Als2 transcripts in mouse central nervous system. These Als2 transcripts were present in Als2 null mice as well as in wild-type littermates and some rescued the zebrafish phenotype. Thus, we speculate that the newly identified Als2 mRNA species prevent the Als2 KO mice from developing severe neurodegenerative disease and might also regulate the severity of the motor neurons phenotype observed in ALS2 patients.

    Photodynamic therapy (PDT) of malignant brain tumors is a promising adjunct to standard treatment, especially if tumor stem cells thought to be responsible for tumor progression and therapy resistance were also susceptible to this kind of treatment. However, some photosensitizers have been reported to be substrates of ABCG2, one of the membrane transporters mediating resistance to chemotherapy. Here we investigate, whether inhibition of ABCG2 can restore sensitivity to photosensitizer chlorin e6-mediated PDT. Accumulation of chlorin e6 in wild type U87 and doxycycline-inducible U251 glioblastoma cells with or without induction of ABCG2 expression or ABCG2 inhibition by KO143 was analyzed using flow cytometry. In U251 cells, ABCG2 was inducible by doxycycline after stable transfection with a tet-on expression plasmid. Tumor sphere cultivation under low attachment conditions was used to enrich for cells with stem cell-like properties. PDT was done on monolayer cell cultures by irradiation with laser light at 665nm. Elevated levels of ABCG2 in U87 cells grown as tumor spheres or in U251 cells after ABCG2 induction led to a 6-fold lower accumulation of chlorin e6 and the light dose needed to reduce cell viability by 50% (LD50) was 2.5 to 4-fold higher. Both accumulation and PDT response can be restored by KO143, an efficient non-toxic inhibitor of ABCG2. Glioblastoma stem cells might escape phototoxic destruction by ABCG2-mediated reduction of photosensitizer accumulation. Inhibition of ABCG2 during photosensitizer accumulation and irradiation promises to restore full susceptibility of this crucial tumor cell population to photodynamic treatment.

  3. mTOR regulates the expression of DNA damage response enzymes in long-lived Snell dwarf, GHRKO, and PAPPA-KO mice.

    Studies of the mTOR pathway have prompted speculation that diminished mTOR complex-1 (mTORC1) function may be involved in controlling the aging process. Our previous studies have shown diminished mTORC1 activity in tissues of three long-lived mutant mice: Snell dwarf mice, growth hormone receptor gene disrupted mice (GHRKO), and in this article, mice deficient in the pregnancy-associated protein-A (PAPPA-KO). The ways in which lower mTOR signals slow aging and age-related diseases are, however, not well characterized. Here, we show that Snell, GHKRO, and PAPPA-KO mice express high levels of two proteins involved in DNA repair, O-6-methylguanine-DNA methyltransferase (MGMT) and N-myc downstream-regulated gene 1 (NDRG1). Furthermore, we report that lowering mTOR enhances MGMT and NDRG1 protein expression via post-transcriptional mechanisms. We show that the CCR4-NOT complex, a post-transcriptional regulator of gene expression, is downstream of the mTORC1 pathway and may be responsible for the upregulation of MGMT and NDRG1 in all three varieties of long-lived mice. Our data thus suggest a novel link between DNA repair and mTOR signaling via post-transcriptional regulation involving specific alteration in the CCR4-NOT complex, whose modulation could control multiple aspects of the aging process. © 2016 The Authors.

    Full Text Available In 2012 and 2013, the selection of foraging habitats and the diet of the Hoopoe Upupa epops were studied in the Goričko area, where a significant population decline of the species has been recorded in the past 15 years. Goričko is an area with a well-preserved traditional mosaic-like agricultural landscape very rich in biodiversity which, however, is disappearing. The diet was determined using automatic camera recordings of prey brought to chicks by parents. Mole crickets Gryllotalpa gryllotalpa were the most dominant prey (35.4% frequency and 81.3% biomass of prey, followed by Scarab beetles larvae Scarabaeidae, caterpillars Lepidoptera larvae and True flies Diptera. Feeding frequency was highest in the period of most intensive chick growth (between 8 and 21 days of age. Selection of foraging habitat was researched by observation of birds during foraging. Hoopoes foraged mostly in mown meadows and grassy courtyards and, to a lesser extent, on sandy cart tracks and road edges. These habitats were characterized by low vegetation and patches of bare ground that enabled Hoopoes to forage efficiently. Home range size was determined using minimum convex polygons. The maximum home range size was between 42.9 and 57.7 ha, while the percentage of foraging habitats within the home range did not exceed 18%. Based on our results, we propose the following measures for effective Hoopoe conservation in the area: maintaining the present range of existing unimproved meadows, stopping the conversion of meadows into fields, restoring fields to meadows, prohibiting the use of pesticides targeting Mole crickets.

    The experiences of small and midsized enterprises (SME) with medical rehabilitation were investigated in the KoRB-Study (KoRB= KOoperation Rehabilitation und Betrieb) for the first time. Opportunities for a targeted cooperation between the statutory pension insurance and these enterprises were explored. Based on explorative interviews, Westphalian employers, members of the works council, occupational health practitioners and employees were interrogated about the image of and their appreciation of medical rehabilitation in the work setting. Experience with rehabilitation and the level of information on rehabilitation were recorded as well as the compatibility of rehabilitation with operative processes in the working site. In addition rehab hospitals were asked about their experience in cooperating with enterprises. 697 employers of small and midsized enterprises, 458 members of the works councils, 73 occupational health practitioners, 47 rehab hospitals and 3 509 employees, who are members of the German Pension Fund of Westphalia, took part in the survey. Especially employers perceived rehabilitation positively and reported good experiences. Among the employees, those who had taken part in rehabilitation showed the highest appreciation. Occupational health practitioners were more restrained in their appraisal. Some of them complained about a lack of sustainability. The different target groups of the survey felt differently well informed about rehabilitation - best ratings came from the occupational health practitioners, worst ratings from the employees. All groups would welcome more accessible information in case of need. Medical rehabilitation in its standard form of "3 weeks full-time" often causes severe logistic problems in SME (e. g., replacement of employee, loss of experience). However the financial burden is perceived as less problematic. Employers favour alternative rehab models, which allow part-time working. Many employees, who expressed a need for

    The objective of this study was to determine the effect of corn silage and quantitative feed restriction on BW, ADG, feed conversion, and carcass composition of White Kołuda W31 geese. Two diets were fed during the rearing period from 22 to 98 d of age: 1) a commercial diet ad libitum, and 2) restricted amounts of a commercial diet and corn silage ad libitum. Each treatment had 2 replicates of 16 birds each. From 99 to 119 d of age, all birds were fattened with whole oat grain alone. Incorporation of corn silage reduced weight gains and caused statistically significant differences in BW at the end of the rearing period (14 wk, 6,625.0 vs. 6,050.0 g; P 0.05). Daily weight gains varied with week of growth, being lowest at 12 wk of age. Birds fed the commercial diet and corn silage had a significantly longer trunk (29.2 vs. 31.0 cm, P dressing percentage (65.0 vs. 74.7%, P Poultry Science Association Inc.

    Full Text Available Both IL-10 and STAT3 are in the same signal transduction pathway, with IL-10-bound IL10 receptor (R acting through STAT3 for anti-inflammatory effect. To investigate possible therapeutic synergism, we delivered both full-length wild-type human (h STAT3 and hIL-10 genes by separate adenoassociated virus type 8 (AAV8 tail vein injection into LDLR KO on HCD. Compared to control Neo gene-treated animals, individual hSTAT3 and hIL-10 delivery resulted in significant reduction in atherogenesis, as determined by larger aortic lumen size, thinner aortic wall thickness, and lower blood velocity (all statistically significant. However, dual hSTAT3/hIL-10 delivery offered no improvement in therapeutic effect. Plasma cholesterol levels in dual hSTAT3/hIL-10-treated animals were statistically higher compared to hIL-10 alone. While no advantage was seen in this case, we consider that the dual gene approach has intrinsic merit, but properly chosen partnered genes must be used.

    Replacement of the warm water of the Soya Warm Current (SWC) and the cold water of the East Sakhalin Current (ESC) occurs seasonally along the coast of the southwestern Okhotsk Sea, and sea ice covers the surface during winter. Pseudocalanus newmani is one of the dominant copepods in coastal waters of the northern hemisphere. To better understand the population dynamics of the copepod P. newmani in coastal areas of the southwestern Okhotsk Sea, this study compared the seasonal variation in P. newmani abundance in Lagoon Notoro-ko and a coastal area of the Okhotsk Sea with regard to developmental stage. We sampled P. newmani in the lagoon, including during the ice cover season, and the coastal waters. Pseudocalanus newmani was abundant at both sites in spring. During summer-fall, adults disappeared from the populations at both sites, whereas the early developmental stages were abundant and dominated the population. Total length of adult females decreased toward summer at both sites. Pseudocalanus newmani abundance in the lagoon increased in early winter, and larger females were found in the populations at both sites. These phenomena at both sites corresponded with seasonal variation in water temperature caused by seasonal water-mass replacement and sea ice.

    The study aims to get a lot information about manufacturers of ancient bronze artifacts and ancient civilization. By KO-standardization method of neutron activation analysis developed in the Nuclear Research Institute, the concentrations of Au, Ag, As, Zn, Sb, Sn elements in ancient bronze alloy samples of 99 bronze artifacts from many excavated archaeological sites at the provinces in Vietnam were determined with uncertainties about ±10%. These elemental concentrations have been utilized in a statistical analysis procedure in order to determine similarities and correlation between the various samples. Th abnormal high of concentrations of noble metals as Au, Ag in ancient bronze indicates that the ancient metallurgists had been interested in role of these metals on sound quality of bronze artifacts. Especially, the concentrations of As in many samples are very high even at about 10%. This gives an evidence that in ancient time the humankind could use bronze As alloy in order to improve quality when they had produced bronze artifacts. (author)

    In this paper, fatigue strength of laser welded butt joint has been investigated. In order to obtain the influence of underfill and pitting, fatigue test was conducted with different sheet thickness and mechanical properties. Fatigue crack initiated at underfill and pitting in the weld metal. Stress concentration factor and hardness of the weld metal were considered to estimate fatigue limit. However, hardness of the weld metal has no significant effect on fatigue strength. As a result, fatigue strength was well estimated by hardness of base metal and stress concentration factor calculated from the shape of underflll and pitting. 7 refs., 9 figs., 5 tabs.

    This paper explains development and examples of application of automated welding devices from a viewpoint of an element technology constituting computer integrated manufacturing (CIM), based on the history of modernization of shipyards that has been achieved to date. In the first step of promoting the modernization, elevating cutting accuracy in the uppermost stream process was thought a starting point of rationalization. What have been achieved therefrom are adoption of the most advanced NC plasma cutting machine, and improvement in the computer aided system for the cutting machines. In addition, a twenty-electrode line welder has been developed, which does not create angle deformation in welding longerons, and can be operated even by unskilled workers. The welder has successfully realized a construction method in which robots can be applied more easily. Further developments have been made on a robot to weld cells, advanced CAD/CAM operation techniques which are linked with data from design, an automatic one-side welding device which can achieve a speed 2.5 times greater than by conventional devices, and an automation device for three-dimensionally bent blocks, whose automation has been regarded difficult. 11 figs., 1 tab.

    Large-scale ships such as VLCC are built at the Kure No.1 Works of IHI (Ishikawajima-Harima Heavy Industry). This paper introduces current status of mechanized and robotized welding at the works. For the sub-assembly with short weld length and horizontal fillet, simplified automatic welders are used in which mag-welding method using CO2 is adopted. The frequent wound welding of member ends can be automatically conducted using welders developed by IHI. In the large-scale assembly processes, remarkable rationalization and highly accurate assembly of flat plate welding have been promoted. Tankers, container ships, and bulk carriers can be treated at the same time. Teaching times of welding robots can be greatly reduced by a technique called parametric treatment. In the future, it is essential to enhance the accuracy of members by introducing the laser cutting during machining processes. Completely self-type mechanization is required as well as large-output laser welding and sensor technology. 3 refs., 12 figs., 2 tabs.

  1. Timescales of mixing and storage for Keanakāko`i Tephra magmas (1500-1820 C.E.), Kīlauea Volcano, Hawai`i

    The last 2500 years of activity at Kīlauea Volcano (Hawai`i) have been characterized by centuries-long periods dominated by either effusive or explosive eruptions. The most recent period of explosive activity produced the Keanakāko`i Tephra (KT; ca. 1500-1820 C.E.) and occurred after the collapse of the summit caldera (1470-1510 C.E.). Previous studies suggest that KT magmas may have ascended rapidly to the surface, bypassing storage in crustal reservoirs. The storage conditions and rapid ascent hypothesis are tested here using chemical zoning in olivine crystals and thermodynamic modeling. Forsterite contents (Fo; [Mg/(Mg + Fe) × 100]) of olivine core and rim populations are used to identify melt components in Kīlauea's prehistoric (i.e., pre-1823) plumbing system. Primitive (≥Fo88) cores occur throughout the 300+ years of the KT period; they originated from mantle-derived magmas that were first mixed and stored in a deep crustal reservoir. Bimodal olivine populations (≥Fo88 and Fo83-84) record repeated mixing of primitive magmas and more differentiated reservoir components shallower in the system, producing a hybrid composition (Fo85-87). Phase equilibria modeling using MELTS shows that liquidus olivine is not stable at depths >17 km. Thus, calculated timescales likely record mixing and storage within the crust. Modeling of Fe-Mg and Ni zoning patterns (normal, reverse, complex) reveal that KT magmas were mixed and stored for a few weeks to several years before eruption, illustrating a more complex storage history than direct and rapid ascent from the mantle as previously inferred for KT magmas. Complexly zoned crystals also have smoothed compositional reversals in the outer 5-20 µm rims that are out of Fe-Mg equilibrium with surrounding glasses. Diffusion models suggest that these rims formed within a few hours to a few days, indicating that at least one additional, late-stage mixing event may have occurred shortly prior to eruption.

    In Nigeria, the first Nuclear Reactor achieved critically on February 03, 2004 at about 11:35 GMT and has been commissioned or training and research. It is a Miniature Neutron Source Reactor (MNSR), code-named Nigeria Research Reactor-1 (NIRR-1). NIRR-1 has a tan-in-pool structural configuration and a nominal thermal power rating of 30 Kw. With a built-in clean old core excess reactivity of 3.77 mk determined during the on-site zero and critically experimental, the reactor can operate for a n.cm-2 .s-1 in the inner irradiation channels). Under these conditions, the reactor can operate with the same fuel loading for over ten years with a burn-up of <1%. A detailed description of operating characteristics for NIRR-1, measured during the on-site zero-power and criticality experiments has been given elsewhere. In order to extend its utilization to include absolute and ko-NAA methods, the neutron spectrum parameters in the irradiation channels: power and critically experiments has been given elsewhere. In order to extend it's the irradiation channels: thermal-to-epithermal flux ration, F; and epithermal flux shape factor, a in both the inner and outer irradiation channels must be determined experimentally. In this work, we have developed and experimental procedure for monitoring the neutron spectrum parameters in an inner irradiation channel based on irradiation and gamma-ray counting of detector foils via (n,y), (n,p) and (n,a) dosimetry reactions. Results obtained indicate that a thermal neutron flux of (5.14+-0.02) x 1011 n/c m2.s determined by foil activation method in the inner irradiation channel, B2, at a power level of 15.5 kw corresponds to the flux indicators on the control console and the micro-computer control system respectively. Other parameters of the neutron spectrum determined for inner irradiation channel B2, are: a -0.0502+0.003; 18.92+-0.14; F = 3.87=0.23. The method was validated through the comparison of our result with published neutron spectrum

    The questionnaire survey on the computer aided materials design (CAMD), and the survey of current domestic and overseas software concerned were carried out to clarify developmental issues. The current elementary technology of CAMD was also surveyed to study its several problems caused with a progress of material design technology due to drastic diffusion of CAMD. This project aims at establishment of a new demanded software, computer chemistry, focusing attention on functional materials such as catalyst, polymer and non-linear electronic materials. Microscopic simulation technology was mainly surveyed in fiscal 1996. Although some fruitful results have been obtained in the fields of medical and agricultural chemicals, organic compounds, proteins, catalysts and electronic materials, such some problems are pointed out as `CAMD cannot handle an actual size of the target system` and `commercially available software are very expensive.` Reliable tool development as elementary technology, and the verification of its applications are thus required. Meso-dynamics, polymers, surface reaction and integrated technological environment attract users` attention. 27 refs., 16 figs., 2 tabs.

    The optical spectra, electron paramagnetic resonance parameters (i.e., the spin Hamiltonian parameters, including paramagnetic g factors and the hyperfine structure constants A{sub i}) and the local distortion structure for the tetragonal VO{sup 2+} in C{sub 6}H{sub 7}KO{sub 7} are theoretically studied based on the crystal-field theory and three-order perturbation formulas of a 3d{sup 1} centre in tetragonal site. The magnitude of orbital reduction factor, core polarisation constant κ, and local structure parameters are obtained by fitting the calculated optical spectra and electron paramagnetic resonance parameters to the experimental values. The theoretical results are in reasonable agreement with the experimental values.

    This paper summarizes materials for aircraft engines. Jet engines are the mainstream today, which are classified according to their operation process into a turbo jet engine, a turbo prop engine, a turbo shaft engine, and a turbo fan engine. Japan has produced 1543 engines in the past decade, almost all of which are supplied to the Defense Agency. Jet engines use mainly Ni-group heat-resistant alloys, titanium alloys and steels. Improvement of engine efficiency has caused turbine inlet temperatures to rise to 1400[degree]C to 1500[degree]C that give rise to grain boundary cracking. To prevent this, discussions are in progress on monocrystal blades replacing the conventional polycrystal precision casts. Intermetallic compounds including Al/Ti are expected especially of use as jet engine constructing materials from their high melting point and formability. Discussions are preceding on ceramics as to coating them intended of improving heat resistance. Composite materials have a problem of insufficient mechanical strength remaining unsolved. 8 figs., 5 tabs.

    Efforts are made to develop a welding design support system capable of increasing reliability and enhancing welding efficiency. Activities are conducted in the six fields of (1) the development of welding process simulation models, (2) development of welded section structure simulation models, (3) development of simulation models for predicting welding caused deformation, (4) integration of the models, (5) analysis of the welding phenomenon, and (6) the elucidation of the defect generation mechanism. In field (1), efforts are made to develop an arc plasma model, a molten pool convective heat transportation model, and a welding process model. In the effort to develop an arc plasma model, studies are made about a stationary axisymmetric arc in its steady state and about a constitutive equation and computation algorithm for developing a model in which a tungsten electrode (cathode) and an arc plasma welding pool (anode) are integrated. Furthermore, the simulation outcomes are experimentally verified. Satisfactory models are obtained as far as qualitative properties are concerned. (NEDO)

    Keeping the pace with recent development and application of laser cladding, hard-facing is used more frequently on turbine blades made of superalloys used in aeroengines. This paper explains the basic principles and features of laser hard-facing technique, welding parameters, and examples of practical use. Examples of practical use include application to turbine blades used in ALF502R-5 turbo fan engines for commuter aircraft and high-pressure turbine blades used in RB211 turbo fan engines for large passenger aircraft. In the former engine, improvement of abrasion resistance was intended at the shroud section where blades are in contact with each other, for which inconel was used as the base material and CO-group alloy as the welding material. The welding used a powder supply system with a laser generator oscillating CO{sub 2} at 5 kW and employing a beam collecting mirror plus scanner to attain a beam covering wider width. Faces with higher performance were obtained than by the conventional TIG welding, and the finishing time was decreased largely. 2 refs., 9 figs., 3 tabs.

    We wanted to analyze the citation trend and to find a way to improve the impact factor (IF) of the Journal of the Korean Radiological Society (JKRS). The number of articles and references, the total citations and self-citations, the IF and the IF excluding self-citations (ZIF) were described by an analysis of Korean Medical Citation Index (KoMCI) during 2000-2005. The total and self citations of the JKRS were compared to that of the Top 5 journals. There was a 57% decrease of papers for 6 years. The Korean references/paper ranged from 0.98-0.85. The number of total citations received steadily decreased from 394 in 2000 to 180 in 2005. The IF (ZF) of the JKRS has been gradually lowered from 0.142 (0.049) in 2000 to 0.063 (0.059) in 2005. Although the total citations that cited all papers published/the annual number of papers was 55% of that of the top 5 journals, the total citations citing papers published within the recent two years was only 24% of that of the top 5 journals. The citation status of the JKRS has steadily decreased for the recent 6 years, and the IF of the JKRS was very low among all the Korean medical journals. To improve the IF, active advertising for the journal members of the importance of the IF is needed to encourage citing JKRS papers that have been published within the recent two years

  5. Influence of organics and silica on Fe(II) oxidation rates and cell-mineral aggregate formation by the green-sulfur Fe(II)-oxidizing bacterium Chlorobium ferrooxidans KoFox - Implications for Fe(II) oxidation in ancient oceans

    Most studies on microbial phototrophic Fe(II) oxidation (photoferrotrophy) have focused on purple bacteria, but recent evidence points to the importance of green-sulfur bacteria (GSB). Their recovery from modern ferruginous environments suggests that these photoferrotrophs can offer insights into how their ancient counterparts grew in Archean oceans at the time of banded iron formation (BIF) deposition. It is unknown, however, how Fe(II) oxidation rates, cell-mineral aggregate formation, and Fe-mineralogy vary under environmental conditions reminiscent of the geological past. To address this, we studied the Fe(II)-oxidizer Chlorobium ferrooxidans KoFox, a GSB living in co-culture with the heterotrophic Geospirillum strain KoFum. We investigated the mineralogy of Fe(III) metabolic products at low/high light intensity, and in the presence of dissolved silica and/or fumarate. Silica and fumarate influenced the crystallinity and particle size of the produced Fe(III) minerals. The presence of silica also enhanced Fe(II) oxidation rates, especially at high light intensities, potentially by lowering Fe(II)-toxicity to the cells. Electron microscopic imaging showed no encrustation of either KoFox or KoFum cells with Fe(III)-minerals, though weak associations were observed suggesting co-sedimentation of Fe(III) with at least some biomass via these aggregates, which could support diagenetic Fe(III)-reduction. Given that GSB are presumably one of the most ancient photosynthetic organisms, and pre-date cyanobacteria, our findings, on the one hand, strengthen arguments for photoferrotrophic activity as a likely mechanism for BIF deposition on a predominantly anoxic early Earth, but, on the other hand, also suggest that preservation of remnants of Fe(II)-oxidizing GSB as microfossils in the rock record is unlikely.

  6. Japan's healthcare policy for the elderly through the concepts of self-help (Ji-jo), mutual aid (Go-jo), social solidarity care (Kyo-jo), and governmental care (Ko-jo).

    Elderly care is an emerging global issue threatening both developed and developing countries. The elderly in Japan increased to 26.7% of the population in 2015, and Japan is classified as a super-aged society. In this article, we introduce the financial aspects of the medical care and welfare services policy for the elderly in Japan. Japan's universal health insurance coverage system has been in place since 1961. Long-term care includes welfare services, which were separated from the medical care insurance scheme in 2000 when Japan was already recognized as an aging society. Since then, the percentage of the population over 65 has increased dramatically, with the productive-age population on the decrease. The Japanese government, therefore, is seeking to implement "The Community-based Integrated Care System" with the aim of building comprehensive up-to-the-end-of-life support services in each community. The system has four proposed elements: self-help (Ji-jo), mutual aid (Go-jo), social solidarity care (Kyo-jo), and government care (Ko-jo). From the financial perspective, as the government struggles against the financial burdens of an aging population, they are considering self-help and mutual aid. Based on Japan's present situation, both elements could lead to positive results. The Japanese government must also entrust the responsibility for implementing preventive support to municipalities through strongly required regional autonomy. As Japan has resolved this new challenge through several discussions over a long period of time, other aging countries could learn from the Japanese experience of solving barriers to healthcare policy for the elderly.

  7. Associations between urinary phthalate metabolites and bisphenol A levels, and serum thyroid hormones among the Korean adult population - Korean National Environmental Health Survey (KoNEHS) 2012-2014.

    Phthalates and bisphenol A (BPA) have been used extensively in many consumer products, resulting in widespread exposure in the general population. Studies have suggested associations between exposure to phthalates and BPA, and serum thyroid hormone levels, but confirmation on larger human populations is warranted. Data obtained from nationally representative Korean adults (n=6003) recruited for the second round of the Korean National Environmental Health Survey (KoNEHS), 2012-2014, were employed. Three di-(2-ethylhexyl) phthalate (DEHP) metabolites, along with benzyl-butyl phthalate (BBzP) and di-butyl phthalate (DBP) metabolites, and BPA were measured in subjects' urine. Thyroxine (T4), total triiodothyronine (T3), and thyroid-stimulating hormone (TSH) were measured in serum. The associations between urinary phthalates or BPA and thyroid hormone levels were determined. Urinary phthalate metabolites were generally associated with lowered total T4 or T3, or increased TSH levels in serum. Interquartile range (IQR) increases of mono-(2-ethyl-5-oxohexyl) phthalate (MEOHP), and mono-(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) were associated with a 3.7% increase of TSH, and a 1.7% decrease of total T4 levels, respectively. When grouped by sex, urinary MEHHP levels were inversely associated with T4 only among males. Among females, mono-benzyl phthalate (MBzP) and mono-n-butyl phthalate (MnBP) levels were inversely associated with TSH and T3, respectively. In addition, negative association between BPA and TSH was observed. Several phthalates and BPA exposures were associated with altered circulatory thyroid hormone levels among general Korean adult population. Considering the importance of thyroid hormones, public health implications of such alteration warrant further studies. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Miejscowe skurcze toniczne to powszechnie spotykany objaw stwardnienia rozsianego (łac. sclerosis multiplex, SM. Do ich zwalczania coraz częściej stosowany jest zastrzyk domięśniowy botuliny typu A. Do analizy statystycznej zaakceptowaliśmy 4 z 10 badanych pacjentów z SM i spastycznością kończyn dolnych oraz 5 zdrowych wolontariuszy. Pacjenci zostali poddani badaniu fMRI trzykrotnie: w tygodniu przed zastrzykiem botuliny A, a następnie w 4. i 12. tygodniu po iniekcji. Podczas badań fMRI probanci wykonywali zginanie i prostowanie stawu kolanowego według planu blokowego, przy czym faza czynna zamieniała się z fazą spoczynku w 15-sekundowych odstępach. Obraz przeciętnej aktywacji pacjentów podczas pierwszej sesji wskazywał, w porównaniu z grupą kontrolną, na istotny wzrost aktywacji obustronnej kory czuciowo-ruchowej płatu czołowego i ciemieniowego. Podczas drugiej sesji w 4. tygodniu aktywacja zmalała do tego stopnia, że statystycznie nie różniła się od zdrowej kontroli. Z kolei w obrazach trzeciej sesji po 12 tygodniach odnotowano w związku z wygaśnięciem efektu botuliny A ponowny wzrost aktywacji niemal do objętości pierwotnej. Wnioski: Stwierdzamy, że aktywacja kory ruchowej odzwierciedla zmiany w obwodowym układzie nerwowym zachodzące podczas leczenia za pomocą botuliny A, w czym prawdopodobnie pośredniczą zmiany w aferentacji. Jest to nowe odkrycie, aczkolwiek nie wykracza poza stwierdzenia podobnych badań przeprowadzonych innymi metodami.

This application first needed explication what the mathematical logic really is—not a science connected with the Aristotelian abstraction of the second degree but formal science unnecessary in a strict reasoning and defining. Then they showed how important was always exactness in Christian thought and wrote some papers in which the modern logic was used in different issues (maybe the most famous was Salamucha’s analysis of Thomas’ proof ex motu of the existence of God.

    Full Text Available Previously, genetic polymorphisms of C12orf51 (HECTD4 (rs2074356 and/or rs11066280 have been shown to be related to alcohol consumption and type 2 diabetes (T2D. This study aimed to prospectively examine whether C12orf51 had an interaction with or independent effect on alcohol consumption and the risk of T2D. The present study included 3,244 men and 3,629 women aged 40 to 69 years who participated in the Korean Genome and Epidemiology Study (KoGES_Ansan and Ansung Study. Cox proportional hazards models were used to estimate HRs and 95% CIs for T2D. rs2074356 and rs11066280 were associated with the risk of T2D after adjusting for alcohol consumption (rs2074356 for AA: HR = 0.39 and 95% CI = 0.17-0.87 in men, and HR = 0.36 and 95% CI = 0.13-0.96 in women; rs11066280 for AA: HR = 0.44 and 95% CI = 0.23-0.86 in men, and HR = 0.39 and 95% CI = 0.16-0.94 in women. We identified that the association of each variant (rs2074356 and rs11065756 in C12orf51 was nearly unchanged after adjusted for alcohol consumption. Therefore, the association of 2 SNPs in C12orf51 with diabetes may not be mediated by alcohol use. There was no interaction effect between alcohol consumption and the SNPs with T2D. However, even in never-drinkers, minor allele homozygote strongly influenced T2D risk reduction (rs2074356 for AA: HR = 0.35, 95% CI = 0.14-0.90, and p-trend = 0.0035 in men and HR = 0.34, 95% CI = 0.13-0.93, and p-trend = 0.2348 in women; rs11066280 for AA: HR = 0.36, 95% CI = 0.16-0.82, and p-trend = 0.0014 in men and HR = 0.39, 95% CI = 0.16-0.95, and p-trend = 0.3790 in women, while alcohol consumption did not influence the risk of T2D within each genotype. rs2074356 and rs11066280 in or near C12orf51, which is related to alcohol drinking behavior, may longitudinally decrease the risk of T2D, but not through regulation of alcohol consumption.

Key words: kinesiotherapy, patient, vascular amputations, lower limbs.   Streszczenie             Amputacja, czyli operacyjne odjęcie kończyny lub jej części, jest jednym z najstarszych zabiegów w historii medycyny. Obecnie, przeważająca część amputacji (ok. 80-90% odbywa się z powodu powikłań chorób naczyniowych. W zależności od obszaru dotkniętego zmianami tkanek oraz rozległości tego procesu, chirurg podejmuje decyzję o poziomie odjęcia kończyny. Po amputacji istnieje ryzyko wystąpienia wielu powikłań, m.in.: zakażenie beztlenowcami, rozejście się rany, martwica skóry, obrzęk oraz przykurcze. W przypadku amputacji planowych ćwiczenia powinno się rozpocząć jeszcze przed operacją, aby przygotować organizm pacjenta do nadchodzących zmian. Kinezyterapia ma na celu wzmocnienie kończyn, zarówno tej, której część zostanie usunięta, a także zdrowej kończyn, która będzie  musiała  przejąć ciężar ciała do czasu zaprotezowania oraz nauczenia pacjenta posługiwania się protezą. Zaleca się ćwiczenia czynne oraz czynne z oporem kończyn górnych, dolnych oraz tułowia, a także ćwiczenia oddechowe. Niezwykle istotne jest przygotowanie psychiczne pacjenta do amputacji poprzez ukazania  możliwości funkcjonowania jak przed operacją. Jednym z jej elementów jest profilaktyka przeciwzakrzepowa, w której skład wchodzą: wysokie ułożenie kończyny, manualny drenaż limfatyczny oraz ćwiczenia bierne i czynne,  pobudzające pompę mięśniową. Przykurcze są jednym z najczęstszych problemów po amputacji, które wpływają negatywnie na proces protezowania.

    Combustion synthesis of porous titan carbide is outlined. In combustion synthesis, exothermic chain reaction, which is induced by igniting at one point of the simple substance mixture, propagates the combustion wave, and the compound is synthesized, which can be sintered by it. By this method, to this day intermetallic compounds, ceramics and high melting point composite materials have been synthesized, and synthetics can be made compact by adding pressure during or just after the reaction. Recently, applying the induction heating jointly, preheating before the reaction and heat treatment after the reaction can be controlled, accordingly, many high melting point inorganic compounds and composite materials can be made by combustion synthesis under pressure.

    When a part of the ground is replaced with artificial materials in the construction of important structures on soft rock foundations, it is desirable for the artificial materials to have the rigidity equivalent to that of the surrounding ground and to be stable in the long term. The article reports a success in the development and utilization of artificial soft rocks satisfying the above conditions by using a raw material produced locally at the construction site. The soft rock aimed at was mudstone belonging to the Neocene period, and the artificial material of soil-mortal system is selected as the equivalent having the same physical properties. Improvements in selection of solidification agents and cohesive soil were especially contrived: taht is, a new material for solidification was developed by mixing blast-furnace cement and gypsum; and the mudstone on the site was used as the cohesive soil by slurrying it to adjust its grain size to homogeneous composition. The artificial soft rock resulting from the above contrivance showed excellent flow, self-leveling, and filling properties at the stage of fresh mortar, and the physical properties after hardning was very similar to those of the natural ground. The long-term stability was also confirmed by the tests on hydration reaction and environmental factors. 2 figs., 1 tab.

    The present paper introduces aluminum foil packaging materials among the relation between packing materials and aluminum. The characteristics of aluminum foil in the packaging area are in its barrier performance, non-toxicity, tastelessness and odorlessness. Its excellent functions and processibility suit best as functional materials for food, medicine and industrial material packaging. While an aluminum foil may be used as a single packing material as in foils used in homes, many of it as a packaging material are used in combination with adhesives, papers or plastic films, or coated or printed. It is used as composite materials laminated or coated with other materials according to their use for the purpose of complementing the aluminum foil as the base material. Representative method to laminate aluminum foils include the wet lamination, dry lamination, thermally dissolved lamination and extruded lamination. The most important quality requirement in lamination is the adhesion strength, which requires a close attention in selecting the kinds of adhesive, laminating conditions, and aging conditions. 8 figs., 6 tabs.

    Basic data for the above subject were collected through technical research on the melt welding of dissimilar metals and through conducting experiments under microgravity concerning the phenomenon of melt welding. The technical research covered reports published in the past 25 years on the welding or bonding of dissimilar materials. For each of the combinations of dissimilar materials of steel, nonferrous metal, and ceramics for producing a transitional joint, investigations were conducted as to whether dissimilar metal welding or bonding was currently feasible under each of the welding or bonding methods, and problems were extracted and remedies were gathered. No melt welding technology was found, however, capable of directly welding dissimilar materials for a transitional joint in which intermetallic compounds were to be formed. In a melt welding experiment conducted under microgravity, investigations were conducted into the effect of surface tension and gravity on convection inside a molten pool and into the bonding of dissimilar materials for which Al/Cu and Al/Mg were involved. It was then shown that microgravity is effective in mitigating stirring and segregation in a molten pool. (NEDO)

    From the position participating as a president of the Singapore Welding Society invited from Japan, the author of this paper introduces the welding situation in that country with emphasis placed on technical exchanges. South East Asia consists of a number of countries in which different kinds of races are present with different cultures. The region is now accomplishing a transfiguration into the manufacturing base of the world. Singapore exists as its core, and is carrying out lubricating functions for industrial growth of the region. It is an important matter how technical transfer will be made from industrialized nations such as Europe, America and Japan into Singapore to meet the above functions. Being different from Japan where a homogeneous society is viewed more importantly, welders, for example, change their place of employment from one to another despite the fact that welders are qualified for their skills by companies independently. Therefore, people concerned with welding in oil refineries, the government agencies and academic societies have developed extensive committee activities for unification of standards for welding skill examinations and for preparation of common implementation law bills. They have spent two years only for preparing the drafts. As a result, a network covering different kinds of business was successfully realized to exchange human resources and information and perform skill management. 4 figs.

    Various forces such as gravity, wave induced force, inertial force etc. compositely act on a ship body from various directions. Therefore, while discussing strength or life of structural elements of ship body, it is necessary to understand the effects of the composite force condition. In this study, fatigue tests of boxing welded joint under rectangular biaxial cyclic loads are performed, the following results are obtained. Even under he biaxial cyclic loads, it is the same as the uniaxial test, the cracks occurred at the boxing weld toes propagate almost in the straight y-direction, but no oblique propagation of the cracks caused by the lad in the y-direction occurs. That the crack at initial stage of the crack progress is improved in y-direction can be illustrated by the facts that the residual stress in x-direction near the toes reaches to the yield stress, and the stress concentration in the welded toes is bigger in x-direction than that in y-direction. But as for prediction of the progress route, a further study including amplitude ratio of the biaxial loads, effects of width of test specimen is necessary. 4 refs., 12 figs., 4 tabs.

    Many indigenous cultures use storytelling as the foundation for the transmission of important cultural information. Stories passed down from generation to generation sometimes teach, record history, provide examples, or inform. One important function of storytelling is the transmission of stories about cultural resilience illustrating how a cultural group has kept strong in the face of adversity. This article shows how storytelling in the Hawaiian culture has been used for this purpose and how the Beamer family has served as the master storytellers of their culture, keeping the culture and traditions alive through their music, dance, and stories.

    Full Text Available When summing up the history of translatology in the second half of the 20th century, the author points to undoubtful achievements of this discipline as well as disputable questions and tasks for the future. She proves that the postmodern conceptions of the exhaustion of literature (Lyotard are not reflected in studies of translation. Just the opposite, this field has been developing dynamically, although its autonomy is still questioned. The chance of translatology is its interdisciplinary character, relation with methodology of linguistic studies, using the theory of interpretation and the theory of intertextuality. Some of the questions which are disputed are: equivalentisation, non-translatability, opposition of archaisation and modernisation. In the sphere of postulates is the synthesis of Polish knowledge on translation, Formation of proper criticism of translation and codification of terminology. All these motifs of considerations are supported by references to the most important conceptions and trends of the 20th century translatology.

    The need to house population in urban areas is expected to rise to 66% in 2050, according to United Nations. The replacement of natural permeable green areas with concrete constructions and hard surfaces will be noticed. The densification of existing built-up areas is responsible for the decreasing vegetation, which results in the lack of evapotranspiration cooling the air. Such decreasing vegetation causes urban heat islands. Since roofs and pavements have a very low albedo, they absorb a lot of sunlight. Several studies have shown that natural and permeable surfaces, as in the case of green roofs, can play crucial role in mitigating this negative climate phenomenon and providing higher efficiency for the building, leading to savings. Such as water saving, what is the main idea of this research.

    There has been tried to apply unified assessment method using hot spot stress, which is effective to evaluate fatigue strength of fillet welded structures for ships and marine structures. This method can be applied to complicated structures and is independent of welding processes. In this study, first, stress analysis has been conducted for two-dimensional fillet welded joint models with various combinations of plate thickness and weld leg length of general fillet structures by means of boundary element method. Then, critical position, which is not affected by local stress concentration due to bead, was determined from the detailed stress distribution in the vicinity of weld toe. As a result, a general equation has been proposed to estimate the hot spot stress by one-point representative method. Second, the fatigue tests of typical fillet welded joints have been conducted by applying this method. Consequently, it was demonstrated that the unified fatigue strength can be evaluated by the S-N data based on hot spot stress range determined from the proposed equation, independent of structural stress concentration. 22 refs., 14 figs.

    The necessary conditions for biocompatible materials such as human bone, joints and teeth are mainly classified into biological condition and mechanical conditions. The former condition is consisted of chemical stability without causing poisoning or allergy, compatibility of good biological tissue, no carcinogenesis and not antigenicity, no decomposition and degradation inside human body, not causing adsorbate or precipitate. As for the latter, appropriate static strength, elastic modulus and hardness together with the characteristics like fatigue resistance, wear resistance and lubricating properties are given. As for other conditions for biomaterials, characteristics as a functional material, workability, adhesion and so forth are important. When surface nitrification of sintered Ti, forging Ti, sintered Ti-6Al-4V and forging Ti-6Al-4V is carried out, the solubility is decreased significantly by surface nitrification. The powder generated by the wear of nitriding Ti-6Al-4V with ultra high molecular weight polyethylene (UHMWPE) is less cell poisoning than the powder caused by the wear of the other alumina, stabilized zirconia, hydroxy apatite with UHMWPE. 16 refs., 2 figs., 1 tab.

    Studies to utilize bistable spontaneous polarization of ferroelectric materials for non-volatile memory have already been started in the 1950`s. Recently, a possibility was indicated on a high-speed non-volatile RAM (FeRAM) with memory cell configuration combined with switching transistors as in DRAMs. This situation has led to performing very active studies on ferroelectric materials and electrode materials used in ferroelectric film cell capacitors. This paper summarizes the above research and development circumstances, as well as their future problems. On the other hand of having shown excellent fatigue resistance in the SrBi2Ta209(SBT) system, improvement has progressed steadily on the Pb(ZR, Ti)03 (abbreviated to PZT) system, which retains the mainstream position as the ferroelectric material for FeRAMs. Aiming at realizing a high integration FeRAM in the future will require discussions on property changes due to use of lower temperature and micronization in film formation, further improvement in relation with degradation such as in imprint, and elucidation of the mechanism. 31 refs., 3 figs.

    In order to control the damage like crack or void formed during the use of structural material by the material itself, it is required to self-detect the damage, to self-judge the state of damage, and to self-control or self-repair the damage finally. Based on the parameter of length, the repair and control is classified into the 1mm-scale functional fine wire and thin film utilization type, 1[mu]m-scale microcapsule type, and 1nm-scale trace element utilization type. For the damage repair and control of functional fine wire and thin film utilization type, the damage is repaired and controlled by pasting thin film or by embedding fine wire of functional material, such as shape memory alloy, Ti-Ni, and piezoelectric ceramics PZT (lead zirconate titanate), on the material surface or inside the material. For the damage repair and control of microcapsule type, is illustrated the control mechanism of high temperature fatigue crack propagation by Y2O3 particles dispersed in the Fe-20Cr alloy. Furthermore, the formation mechanism of self-repairing film by the trace element is also illustrated. 13 refs., 5 figs.

    The present report explained light weight and high strength materials which are strong against the corrosion and fatigue, and economical. Also explained were their joining technologies for the commercial jet plane production. Resin composites are acceleratedly used as light weight and high strength materials. Fiber to be used is heightened in strength by replacing the glassfiber by the hybrid and carbon fiber. As measures against the drop in both strength around the drilled holes, and compressive strength due to the separation between layers and dehumidification, which drop is a defect generated in the composite, improving measures are taken such as enlargement of allowable strain by carbon fiber of a medium elastic modulus, use of resin base hardly degraded by the dehumidification and diffusion of high toughness resin. Metallic materials are also heightened in characteristics. For the joining technologies, measures are progressively taken against the strength damage around the drilled holes and electric corrosion by fasteners in the composite. Also for the tightening of metallic materials, the fatigue strength is designed to be heightened by the introduction of compressive residual stress. Both thermal degradation and stress in the hardening process must be taken into consideration for the structure use adhesives which are mainly of an epoxy system. The corrosion control is indispensable at the time of etching for the metallic adhesion. The welding was also explained. 16 refs., 7 figs., 2 tabs.

    Aluminum, GFRP and composite of aluminum coated with carbon as structural materials for wind turbine blades were bending-tested, to improve blade bending stiffness, understand stress conditions at each position, and clarify structural dynamic strength by the bending-failure test. It is possible to estimate stress conditions at each position from the test results of displacement and strain at each load. The test results with GFRP are well explained qualitatively by the boundary theory, known as a theory for composite materials. The test gives reasonable material strength data, useful for designing wind turbines of high functions and safety. The results of the blade bending-failure test are in good agreement with the calculated structural blade strength. It is also found that GFRP is a good material of high structural strength for wind turbines. 8 refs., 6 tabs.

    Harmonized molecular materials (HMM) were researched to create functional materials adaptable to needs such as environmental harmony and high-efficient conversion in post-industrial society and aging society. Superior mechanisms function efficiently in organisms for perception, transmission and processing of information, and transport and conversion of substances. These functions are caused by harmonization between organic molecules, or organic molecule and metal or inorganic substance. HMM is a key substance to realize these functions similar to those of organisms artificially. It is the purpose of this research to develop HMMs, reform production process by innovating separation and conversion technologies, and finally realize molecular chemical plants. This research also develops high-efficient devices to contribute to the information society, and progresses the industry of bio-functional materials such as high-sensitive bio-sensor. The functions, applications and creation technologies of three kinds of HMM such as assembly, mesophase and microporous materials were researched in fiscal 1995. 956 refs., 128 figs., 13 tabs.

    As functional material to satisfy various needs for environmental harmonization and efficient conversion for information-oriented and aging societies, HMM were surveyed. Living bodies effectively carry out transmission/processing of information, and transport/conversion of substances, and these functions are based on harmonization between organic molecules, and between those and metal or inorganic ones. HMM is a key substance to artificially realize these bio-related functions. Its R & D aims at (1) Making a breakthrough in production process based on innovation of material separation/conversion technology, (2) Contribution to an information-oriented society by high-efficiency devices, and (3) Growth of a functional bio-material industry. HMM is classified into three categories: (1) Assembly materials such as organic ultra-thin films (LB film, self-organizing film), and organic/inorganic hybrid materials for optoelectronics, sensors and devices, (2) Mesophase materials such as functional separation membrane and photo-conductive material, and (3) Microporous materials such as synthetic catalyst using guest/host materials. 571 refs., 88 figs., 21 tabs.

    Computer chemistry was investigationally studied. The advance of theoretical chemistry is indispensable to the design of materials, and the theory and high speed computational method are expected which can simulate the real system with more accuracy. It is basic to simulate structures and physical properties of structural molecules and the aggregate, but the meso region, the intermedium region between structural molecules and the aggregate, has became regarded as important. Rough visualization models in high polymer materials and the progress of computational software/hardware of quantum chemistry/molecular dynamics such as catalyst become necessary. Seamless zooming is proposed as a concept of the software which simulates materials from micro/macro/meso viewpoints. Moreover, to make the most of computer chemistry, an integrated system is necessary which generally handles computational software, database, etc. For the development of software, indispensable is the demonstrative verification by a combination of experiments and researchers. Under a commission from NEDO, the investigational research was conducted as a leading study during fiscal 1996 and 1997 to view the course of the research. 17 refs., 37 figs., 5 tabs.

    This paper describes the semiconductor packaging and molding compound materials. Major constituents of the molding resins are epoxy resin and inorganic silica, to which various additives are added. In order to make thin packages, biphenyl-based resins with low viscosity are often used in response to high fluidity. To fill the clearance less than 100 {mu}m, size adjusting techniques of the inorganic silica are also significant apart from resins. Since it is heated under the water absorption condition for the packaging in substrates, low water absorption, high adhesion, high strength and low stress are required to avoid peeling and cracking due to the vapor pressure of moisture. Generation of voids is also a problem. Improvement of productivity by reducing the processing period is also significant. In response to the strict environmental regulation, disuse of brominated epoxy and antimony oxide which are flame retardants in the molding resins is an urgent problem to be solved. For the epoxy resins, bisphenol A is to be regulated as a mutation substance. The cost reduction is required with keeping current quality kept. 1 fig.

    This paper describes a report on the material committee for coal gasification technology development in fiscal 1988. The in-plant test on new materials has performed information investigation on use characteristics and use records of new materials. A sulfurizing corrosion resistance test showed that the aluminum-chromium diffused and permeated material and the molten aluminum plated material stabilize the coated surface and have high corrosion resistance. Ceramics painted lining material was evaluated unusable in a steam diffusion test. Phenol resin was found sufficiently usable as a result of giving the stress test at 100 to 150 degrees C. In developing a let-down valve, a high-velocity water slurry injection test revealed that CVD coating of Ti (C, N) has high effect of suppressing the erosion damage. In a high-velocity powder injection test, PVD coating of TiN and CVD coating of TiC were found to show good erosion resistance. Tests and researches were performed to evaluate durability of furnace materials for manufacturing gasified hydrogen, and elucidate conditions to cause iron oxide burst. Evaluation on repairing techniques, and improvement on durability were also executed. (NEDO)

    In this session for the new materials, almost all of them were the presentation on the fiber reinforced plastics (FRP). Based on these facts, the topics of new materials about PC centered around FRP, and consequently it was found that how it was expected as the new materials and how it is being watched with keen interest. Even in FRP, the presentations on the carbon fiber reinforced plastics (CFRP) and aramid fiber reinforced plastics (AFRP) were a little bit more than those on the glass fiber reinforced plastics (GFRP), and therefore they were felt to be predominant. Although the ones about a fundamental study on the material characters of FRP held approximately 70%, as a content, there were 6 presentations on the design and execution of the actual bridges in which FRP was used for the PC take-up materials and the oblique cable of cable-stayed bridges, consequently it was found that FRP did not stay at a study stage, and was already shifting to the actual application stage. However, at the current situation, there were many of experimental ones like the small scale bridges in the golf courses, and furthermore it can not be said that a guideline for the design and execution is sufficiently established. 2 figs.

    Field welding an I-section girder forms details having scallop at the web, whereas the presence of the scallop causes shear deformation and localized stress concentration. Therefore the details in joints with low fatigue strength are ranked as class G in the fatigue design guideline published by JSSC. With special notice on the effect of shear, the present study has varied the phase by using multiple number of jacks; so loaded that the direction of the shear force will change; assumed field welding of a bridge constructed with a few number of main girders; and verified fatigue strength at thick flange plates. In addition, in order to improve the fatigue strength, elucidation was given on the effect of grinder finish at boxing welds. From these results, items to be considered were made clear when structural details are designed and fabricated, in which I-section girders having scallop are welded in fields. Furthermore, it was considered that stress in web plate jointing welding bead becomes relatively higher than local stress in boxing, which was indicated as a point requiring precaution. 8 refs., 20 figs., 2 tabs.

    Wastewater containing organic pollutants is generally treated by the biological methods like the activated sludge process, etc. But these biological methods are not necessarily applied to the wastewater with high salt content generated at pickles making plants, etc.. In this report, with the objective of application of the electrolytic oxidation treatment to the organic wastewater with high salt content of pickles making plants, the effects of such conditions as pH, temperature and current, etc. on the treatment rate and treatment efficiency were examined, furthermore, the treatment process was simulated on the basis of a simple reaction model, and its simulation results were compared for study with the experimental results. The results are shown below: No effect of pH was observed, hence no pH control is required; The higher temperature of the wastewater accelerates the treatment rate; It was considered that in high temperature, a loss due to autolysis of hypochlorous acid increases, but the current efficiency of generating hypochlorous acid increases too and since the latter effect is bigger, the above phenomenon occurs. The current has a small effect on the treatment efficiency. With the simple reaction model, the change of residual chlorine concentration, etc. with time can be reproduced semiquantitatively. 7 refs., 6 figs.

    Rice (Oryza sativa) has the potential to undergo rapid internodal elongation which determines plant height. Gibberellin is involved in internode elongation. Leucine-rich repeat receptor-like kinases (LRR-RLKs) are the largest subfamily of transmembrane receptor-like kinases in plants. LRR-RLKs play important functions in mediating a variety of cellular processes and regulating responses to environmental signals. LRK1, a PSK receptor homolog, is a member of the LRR-RLK family. In the present study, differences in ectopic expression of LRK1 were consistent with extent of rice internode elongation. Analyses of gene expression demonstrated that LRK1 restricts gibberellin biosynthesis during the internode elongation process by down-regulation of the gibberellin biosynthetic gene coding for ent-kaurene oxidase.

    This is the report No. 98 issued by the Inorganic Material Research Institute. An intelligent material is a substance and/or material which responds intelligently to environmental conditions and exhibits functions. One of the features of amorphous materials including amorphous glass is a large freedom in chemical composition. These materials maintain order in short distance, but have as a whole the turbulent and specific atom orientation. Therefore, high tolerability in selecting the composition, and diverse synthesizing methods are available. A wide range of utilization may be conceived, such as introduction of the state of electrons having different valences in a structure, and the diverse chemical combinations. Patterns of existence of polyhedrons having different orientations, and how they are connected correlate closely with an external environment. Intelligent materials have high freedom against change in the external environment and are suitable to exhibit intelligent functions. Setting heat and light as the external conditions, attempts have been made on search and creation of intelligent materials based on state change induced by interactions between the two factors. Fundamental studies have been made on synthesis of different environment responding glasses and films, and on factors and phenomena for exhibition of the intelligence. 62 refs., 91 figs., 8 tabs.

    R and D activities currently being undertaken for Korean Helium Cooled Solid Breeder (HCSB) Test Blanket Module (TBM) include joining technologies of structural materials, breeder pebble material development, and measurement of pebble bed characteristics. The joining performance of ferritic-martensitic steel is evaluated. TIG welding for ferritic-martensitic steel is evaluated to find welding conditions with two different current modes. The fabrication methods of lithium silicate powder and lithium titanate pebble are under development using special process. The Li 2 TiO 3 pebbles showing an average diameter of 1.8 mm was fabricated by water-based sol-gel method. The Li 4 SiO 4 powder with the particle size of about 200 nm was synthesized by PVA polymer solution method. The method of silicon carbide coating on the graphite pebble is investigated, and its possibility is verified based on the coating results on the graphite plate. Sputtered SiC coating layer was crystallized by high temperature heat treatment. The measurement method and database of the thermal properties of the pebble and pebble bed are important for the design of TBM as well as breeding blanket. The initial characteristics of the pebbles are assessed measuring the effective thermal diffusivity of graphite pebble by laser flash method.

    A fabrication procedure for the manufacturing of the HCCR TBM sub-module was performed and small mock-ups were fabricated using an E-beam and laser beam weld to verify the manufacturing procedure and method of the HCCR TBM sub-module. To establish and optimize the welding procedure in an E-beam weld from ARAA material, the distortion and radiographic tests were carried out from the E-beam weld results. It could be noted that a small amount of distortion occurred, but the values are small enough to neglect for the fabrication. In addition, a helium leak test and water pressure test will be performed for verification of the fabricated small mock-ups.

  16. ZAKI: a windows-based ko standardization code for in-core INAA

    Ojo, J.O.; Filby, R.H.

    2002-01-01

    A new computer code ZAKI, for k o -based INAA standardization, written in Visual Basic for the WINDOWS environment is described. The parameter α measuring the deviation of the epithermal neutron spectrum shape from the ideal 1/E shape, and the thermal-to-epithermal flux ratio f, are monitored at each irradiation position for each irradiation using the ''triple bare monitor with k o '' technique. Stability of the irradiation position with respect to α and f is therefore assumed only for the duration of the irradiation. This now makes it possible to use k o standardization even for in-core reactor irradiation channels without an a priori knowledge of α and f values as required by existing commercial software. ZAKI is considerably versatile and contains features which allow for use of several detectors at different counting geometries, direct inputting of peak search output from GeniePc, and automatic nuclide identification of all gamma lines using an in-built library. Sample results for two certified reference materials are presented

    Full Text Available Objectives: To determine prevalence of undesirable, work-related skin lesions and their localizations in dental professionals and students, and to collect data about diagnostic procedures they undergo and skin care they take when these lesions occur. Subjects and methods: Our research included 444 respondents (dentists, dental assistants, dental technicians, dental students who filled out a questionnaire. They were asked to specify if they had observed any lesions on their skin and where; if they had undergone any treatments and in what way; if they had undergone any allergy tests; and if they had taken any protective measures. Results: Of all the respondents that took part in the survey, 249 (56.1% reported undesirable skin reactions commonly on their hands and fingers (96%. Before our survey, only 15% of them had seen a dermatologist, while 33% had undergone allergy tests (without a dermatologists’ clinical examination. Also, 45% of them sometimes used soaps for sensitive skin and the majority (61% of them used protective hand creams 1-2 times per day. Conclusion: Although a large number of dental professionals and students have noticed work-related skin lesions, only some of them sought dermatologists’ professional help and most of them did not take care of their skin adequately when those lesions occurred. According to the results of this study, it is necessary to take additional preventive measures to increase dental professionals’ and students’ awareness of occupational dermatoses and adequate skin care.

    Highlights: • Integrated analysis is performed with the conventional CFD code (ANSYS-CFX). • Overall pressure drop and coolant flow scheme are investigated. • Manifold design is being performed considering flow distribution. - Abstract: To develop tritium breeding technology for a Fusion Reactor, Korea has participated in the Test Blanket Module (TBM) program in ITER. The He Cooled Ceramic Reflector (HCCR) TBM consists of functional components such as First Wall (FW), Breeding Zone (BZ), Side Wall (SW), and Back Manifold (BM) and it was designed based on the separate analyses for each component in 2012. Based on the each component analysis model, the integrated model is prepared and thermal-hydraulic analysis for the HCCR TBM is performed in the present study. The coolant flow distribution from BM and SW to FW and BZ, and resulted structure temperatures are obtained with the integrated model. It is found that the non-uniform flow rate occurs at FW and BZ and it causes excess of the design limit (550 °C) at some region. Based on this integrated model, we will perform the design optimization for obtaining uniform flow distribution for satisfying the design requirements.

    A workstation-based real-time simulator for two-loop pressurized water reactor plants is developed for classroom training in support of a full-scale simulator, on-site transient analysis, and engineering studies. The present simulator consists of three functional modules: plant module, graphic module, and man-machine interaction module. The plant module includes models for the core kinetics, reactor coolant system, steam generator, main steam line, balance of plant, and control and protection system. Each of the models is optimized to obtain the capability of real-time simulation. The graphic module is designed to provide the user with more information at a glance by dynamically displaying schematic diagrams of the systems, symbols indicating the operating status of each component, trend curves, and the main control room. As tools for the man-machine interface, the man-machine interaction model uses a color cathode ray tube monitor, a standard keyboard, and the mouse. The interactive communication module receives parameters from the user via the keyboard and mouse, and transfers them to the plant module so as to enable the user to perform his specific actions. This module provides the user with various initiating events (malfunctions and manual controls) through SYSTEM, CONTROL ROOM, and ACCIDENTS menus, and thus a wide range of nuclear steam supply system transients can be easily simulated. The FISA-2/WS is verified through comparisons with analytical solutions, separated tests and integral tests, and predictions by RETRAN-2 and RELAP5/MOD3

    Research and development is started of materials for constituting a liquefaction reactor which is the primary apparatus in the coal liquefaction process. Tested in the basic research on the designing of alloys for the reactor are Cr-Mo-V-Ti based alloys prepared by adding V, Ti, and B to Cr-Mo based alloys presently in use as materials for pressure vessels. They are melted and 50kg test ingots of steel are prepared, and an alloy with a constitution of Low Si-3%Cr-1%Mo-0.25%V-0.02%Ti-0.002%B is selected. In the designing of alloys to serve as stainless steel overlay welding materials and in the development of basic welding technologies, studies are conducted in search for materials that exhibit excellent durability under the conditions of liquefaction reaction and for technologies in this connection. These are accomplished using a test device installed this fiscal year, which is capable of reproducing high-temperature high-pressure hydrogen atmosphere. As the result, basic technologies are acquired, which will enable the achievement of the goal. In the study of on-site production technologies using medium-size ingots as the materials, an 85-ton medium size steel ingot of a new chemical constitution of Low Si-3Cr-1Mo-1/4V-Ti-B is melted, and a shell which is 400mm in thickness and 2m in internal diameter is forged, and the shell is subjected to a property and performance qualification test.

    Trends of research on carbon based composite materials were surveyed through studying various reports and technical literature and evaluation of the project named above was conducted through holding interviews with researchers. In the survey of research trends for which technical literature perusal was the main tool, it was found that in most technical articles the important task was the enhancement of oxidation resistance, that SiC coating was in use for this purpose, that the technology would meet its limit at 1,600-1,700 degrees C, and that it would turn useless at temperatures beyond 1,800 degrees C. For the evaluation of the project, interviews were held with nine researchers not taking part in the project. The researchers favored the project as far as the popularity of the project and the main implementing body and system were concerned, but they negatively evaluated the project's goal of using such materials at 2,000 degrees C in the atmosphere. This research report comprises four chapters which cover (1) trends of research on C/C (carbon/carbon) composites, (2) a summarized research report on C/C composites, (3) survey of patents associated with C/C composites, and (4) opinions expressed toward the project and the results of evaluation conducted on the same.

    Development of nenroactive materials to improve neuronal defects is one of the most important subjects in Japan that will soon become a aging society. In this project, basic research for neuroactive molecule was performed to develop technology for neuronal regeneration, regulation of synaptic activity and interface between artificial surface and living neurons. A novel neurite promoting factor was discovered and its cDNA was cloned. Mutagenesis in vitro showed that a functional region of this factor located in a polypeptide of less than 50 aminoacids. Using neuronal culture, synapse formation was found to depend on two modes of activities and long-lasting synaptic potentiation was demonstrated to depend on a macromolecules released from pre- or postsynaptic neurons. To regulate nervous activities, photoactivated caged-peptide was developed and confirmed to change in affinity to its receptor. Neurons were cultured on substrates paterned by microlithography.

    This paper describes use technologies of organic materials for selecting them under various environmental conditions. FRP is superior in mechanical strength and chemical resistance, and suitable as anticorrosion structural materials. Its chemical resistance is dependent on matrix resins. Simple polyolefine system resin is superior in chemical resistance and cost, however, because of its poor mechanical strength, it is mainly used for small parts. The composite structure is used for middle tanks or piping materials where the inside surface contacting solution is lined with chemical resistant resins such as PP and PVC, while the outside surface is reinforced with FRP. Various lining materials and lining methods are used. The following materials are used for lining: liquid resin type one such as tar epoxy resin, melting powder type one such as PE, PP and fluororesin, laminated glass fiber type one using cold setting polyester and thermosetting phenol resin, compound type one of scale-like glass flake and resin, and rubber or plastic sheet material. It is important to select optimum material for lining. 1 fig., 2 tabs.

    The technical art `Bekko` is one of the traditional technologies in Japan, and the materials of `Bekko` are shells of hawksbills. However, the industry of `Bekko Work` has been facing a crisis recently, because the import of turtleshell is restricted. We have therefore tried to develop new materials as substitutes for the turtleshell by utilization of horn. The noteworthy aspects in this study are as follows: (a) It has been clearly established that the horn could be reformed with amber color similar to that of turtleshell by chemical treatment using hydrogen peroxide (H2O2). (b) It is also of interest that we produced new materials like `Bekko` by mixing horn powder and turtleshell powder at the appropriate ratio and molding them in the temperature range of 110-120{degree}C. 1 ref., 6 figs., 3 tabs.

    In order to create new functional organic thin film materials, basic data were examined under micro-gravity. Polymerization of pyrrole was affected by micro-gravity after a few minutes from the beginning of reaction. Although relatively uniform particles were obtained, the particle size was finely dependent on conditions. Electrolytic polymerization of conductive organic thin films was yet unstable in reproducibility. On orientation control and thin film formation of protein under gravity-free environment, electrodeposited films were obtained using bacteriorhodopsin film suspension by applying voltage of 6.4V for 9s after 1s from falling. The reproducibility of the number and area of molecular layers was poor. On the study on the formation process of organic thin films, creation of homogeneous films is probably possible by filtration from suspension under reduced pressure under micro-gravity for a short time. Trial linear polymer tied in a row was obtained by capillary injection of dense polymer solution. The viscous fingering phenomenon of viscoelastic bodies under micro-gravity was compared with that on the ground. 11 refs., 36 figs., 1 tab.

The purpose of this study is to examine the possibilities of developing new applications of asphalt to the anti-vibration, vibration-control and anti-noise materials, though its uses have already been diversified in fields other than for road paving, due to excellent performance regardless of cheap cost. In the paper, firstly, under a title of what is asphalt, the history, the composition and internal structure of asphalt were considered. Secondly, the dynamic characteristics of asphalt were considered. And lastly, under a title of the application of asphalt, examples of the application of asphalt to anti-noise materials were examined in the field of architecture, automobile and civil engineering respectively. Especially, in the field of civil engineering, improvements of flexibility and vibration-control by using the cement asphalt mortar (CAM) in the anti-vibration A-type slab track for railway, and also anti-noise and anti-vibration technologies applied to the road pavement body by using the ferrite asphalt were reviewed. 11 refs., 10 figs., 8 tabs.

    Creation of new functional organic materials for the medical application has been investigated under the microgravity. Facilities of the Japan Microgravity Center were used for this study. For the high-speed synthesis of uniform polymer particles under the microgravity condition for ten seconds, appropriately good results were obtained in the oxidation polymerization of pyrroles. For the synthesis of organic conductive thin films by the electrolytic polymerization, the resistance of electrolyte became larger in the microgravity field. It was required to set conditions so as to enhance the effects of microgravity environment. For the orientation control and thin film formation of proteins, the bacteriorhodopsin was examined. It was found that the microgravity improved the quality of electrocoatings. When the surface tension and viscosity of coating liquid were appropriately controlled under the microgravity, thin films were able to be prepared by utilizing a change from 1g to {mu}g. When the high viscosity fluid is placed in the artificial two-dimensional space composing of two parallel plates, and the low viscosity fluid, such as air, is injected into the above, the interface grows in the finger shaped pattern, namely, viscous fingering. The influence of gravity on this phenomenon was also investigated. 11 refs., 45 figs., 5 tabs.

    Mechanical properties and failure behavior of weft knitted fabric reinforced composites were studied. Aramid fiber was used as reinforcement (knitting fiber), and epoxy resin as matrix. Different tensions were applied to the weft knitted fabric in a course or wale direction to prepare 5 kinds of fiber reinforced composites with different densities of the knitted fabric, and tensile test pieces were thus provided by cutting each composite in a course or wale direction. As a result, the weft knitted fabric reinforced composite offered a dynamical anisotropy, and the tensile strength of the test pieces was higher in wale direction than course one. Fracture in a course direction occurred at the section with extreme low fiber content, while fracture in a wale direction occurred at a loop interlocking region due to stress concentration. The tensile strength was constant or increased in a course or wale direction by stretching the knitted fabric before molding, respectively. 21 refs., 15 figs., 2 tabs.

    Solvothermal reaction is reaction under high temperature and high pressure, which is expected to fabricate new functional materials. In this study, the materials are classified into two fields, i.e., inorganic materials, metals and their composites and organic materials and their composites. The current status of R and D of production and processing technology in each field is surveyed and the prospect of it is discussed. For the inorganic materials, metals and their composites, it is explained that very fine metal oxide particles, complex oxides, single crystals, whiskers, compounds with layer structure, metastable compounds, ion conductors and catalysts with high ability could be produced only by controlling the solvothermal reactions in atomic order. For the organic materials and their composites, surveyed results of the solvothermal technique using non-aqueous solutions are mainly provided. The necessity of a national project for researches on the solvothermal reactions is proposed from the viewpoint of resource, environment and energy. 777 refs., 38 figs., 26 tabs.

    For development of materials for heat exchangers under severe corrosion environment due to ultra-high temperature coal combustion gas, basic data were surveyed. On the study in fiscal 1996, the corrosion resistance of one kind of commercially available material and 2 kinds of created materials was studied by coal slag coating test. The commercially available material was subjected to high- temperature corrosion tests of 1500 and 1550degC for a long time. The result showed that SiC is most excellent in the above temperature range. On new materials, 7 kinds of Cr2O3 system ceramics such as Cr2O3-Al2O3 system and Cr2O3- MgO system were selected considering high-temperature corrosion resistance, and the optimum composition and fabrication process of the new materials were studied. High- temperature corrosion tests, and measurement of thermal conductivity and thermal expansion were carried out for every specimen. The result suggested that some materials of Cr2O3- Al2O3 system are promising. 23 refs., 76 figs., 23 tabs.

    Recent diesel engines require a higher performance and a longer life. Due to higher cylinder pressure, the operating load and temperature of piston pin bushings become higher. Therefore, higher load capacity, higher wear resistance and higher corrosion resistance are required for piston pin bushings. For this reason, we have studied the effect of components added to copper alloy upon the corrosion resistance and the effect of hard particles dispersed in copper matrix upon the wear resistance and the influence of hard particles on the machinablity of materials. Based on the experimental results, we have developed a new bushing material improving wear and corrosion resistance. 17 figs., 3 tabs.

    Increasing vehicle speed and power, high-performance synchronizer ring of manual transmission is required. We develop double layer sintered synchronizer ring for high performance and cost reduction. The main structure is consisted of ferrous sinter for high strength. In this paper, friction materials of sintered synchronizer ring are studied. We can get the good friction and anti-wear property by means of hard particles (FeTi, ZrO2), solid lubricant (Graphite) and suitable porosity in brass sinter matrix. And we also achieve high joining strength between double layers adding Cu-P material. 6 refs., 13 figs., 2 tabs.

    R and D on harmonized molecular materials aim at establishment of the technology fabricating self-assembled organic molecular films on solid surfaces which have potentials of mechanical response to electric fields, electroluminescence or optical functions. Molecule harmonization expresses new structures and functions difficult to be expressed by each molecule alone, by cooperative interaction between molecules due to noncovalent bond. Functional thin films were developed by controlling alignment and/or arrangement of molecules with an aid of self-assembling processes. Thiol compounds with larger dielectric anisotropy were synthesized as electric field responsive self-assembled films. {pi}-conjugated compounds composed of phenyl-capped oligothiophenes were synthesized as electroluminescent self-assembled films, and their high crystallinity and efficient electroluminescence were found. Heat- and solvent-resistant lyotropic liquid crystalline (LLC) aligning polymers such as polyamine and polyimine were synthesized as new optically functional LLC dye self-assembled films. (NEDO)

    It corresponds to an information relating to defect formation due to residual stress and its accompanying defect formation to find out the period of phase-transformation and expansion volume on the transformation forming at welding. In order to estimate texture of the heat affected zone, there is an SH-CCT diagram, which is important on weld metallurgy. However, this is formed by giving a thermal recycling to a small size specimen under stress-free, which has some problems to estimate the transformation starting period in actual welding. And, the expansion volume containing the transformation cannot be found out directly by this. In this study, as the first step adaptable to this problem with laser speckle method measurable with non-contact and high precision, a linear heating with TIG to a SUS304 stainless steel thin plate without transformation was executed at first, the strain behavior accompanied with it was confirmed. Secondly, using a thin plate of 9% Ni steel showing any transformation at comparatively low temperature, probability of a phase transformation detection was investigated on a way of cooling by executing resemble linear heating. As a result, the laser speckle method was confirmed to be adaptable to this problem. 14 refs., 17 figs., 1 tab.

    In order to examine fatigue behavior of boxing welded joints of anticorrosion aluminum A 5083 P-O alloy, the residual stress measurements, static loading tests, elastic finite element analyses, constant amplitude fatigue tests, and random fatigue tests were conducted. For a load wave in the random loading fatigue tests, a direct current component, a zero-mean narrow band random process, and a high frequency component were combined and superimposed, to examine the effect of the high frequency component and the effect of the stress cycle count method and the mean stress correction on the life estimation. For the fatigue analysis, a reference stress, such as that considering the structural stress concentration, was proved effective in reducing the amount of scattering in the fatigue test results and in improving the life estimation accuracy. Accordingly, for the actual scale measurements, it is insufficient only to measure the stress at points far from the crack initiation place. It is required to analyze the fatigue by measuring the reference stress same as the basic data acquisition tests in the laboratory. 4 refs., 21 figs., 4 tabs.

    Full Text Available Meat consumption has been shown to be associated with cardiovascular disease (CVD risk in Western societies; however, epidemiological data are limited on the Korean population. Therefore, we examined the associations between unprocessed meat consumption and CVD incidence in Korea. Data were derived from the Ansung-Ansan cohort (2001–2012, including 9370 adults (40–69 years without CVD or cancer at baseline. Total unprocessed meat consumption was estimated as the sum of unprocessed red meat (beef, pork, and organ meat and poultry consumption. In the fully adjusted Cox regression model, the relative risks of CVD across increasing quintiles of total unprocessed meat intake were 1.0 (reference, 0.72 (95% confidence interval (CI: 0.55, 0.95, 0.57 (95% CI: 0.42, 0.78, 0.69 (95% CI: 0.51, 0.95, and 0.69 (95% CI: 0.48, 0.97, but no significant linear trend was detected (p for trend = 0.14. Frequent poultry consumption was significantly associated with a decreased CVD risk; this association showed a dose-response relationship (p for trend = 0.04. This study showed that a moderate intake of total unprocessed meat was inversely associated with CVD risk. A significant inverse association between poultry consumption and incident CVD was observed in Korean adults, requiring further confirmation in other populations.

    Full Text Available Globalization involves a number of eco-social challenges for cities, which manifest themselves differently onthe local level. Through their enormous economic, political and demographic significance, cities play an extraordinarily important role in the reflexive relationship between the global and the local, which Robertson (1995 describes as glocalization. In consideration of the concept of urban governance, this paper discusses the effects of global dynamics on the local eco-social problem solving capacity in cities. The paper draws five conclusions: (1 Global development goes hand in hand with isomorphic change on the local level. (2 Institutional changes in cities have highlighted the importance of the concept of urban governance. (3 Urban governance has, first and foremost, elitist tendencies – the dogma of the entrepreneurial city has gained ground. (4 Urban governance, at the same time, brings along egalitarian tendencies – the inclusive city is the conceptual counterpart of the entrepreneurial city. (5 Eco-social glocalization is a matter of values.

    Central Japan is the boundary region among the Northeast Japan arc (NEJ), which was parted from the Honshu arc accompanying the basin in the Japan sea area and the bending of Japan Islands, the Southwest Japan arc (SWJ) and the end of the Izu-Bonin arc (IOA), and involves the specific volcanic activity. In this report, the geohistory of the Late Cainozoic era in the central Japan was re-arranged and the neotectonics of the central Japan was tried to reorganize. Especially from a viewpoint that the central Japan is a juncture between the north end of the volcanic arc IOA (Fuji, Norikura and Hakusan volcanic belts) and the southwest end of the volcanic arc NEJ (Nasu and Chokai volcanic belts), the relation between the volcanic activity and tectonics from the Pliocene to Pleistocene has been mainly handled in the Hida region east of the Hakusan and in the northern Fossa Magna region. In addition to it, the tectonics was pointed out to be an indication of mechanical jointing state with IOA. Then the results of IOA drilling according to ODP, Leg 129 were referred as well, in order to compare with the transition of more typical volcanic activity in IOA. 61 refs., 4 figs.

    Full Text Available In this paper I will engage in the theory of American Marxist Fredric Jameson. To begin with I will give an overview of his Marxistic hermenautics and his concept of political unconscious. According to Jameson, every artistic text contains three levels of political unconscious: textual level, social level and historical level. At all three levels it is possible to detect a certain contradiction. At the first level, this contradiction is a textual and formal one, at the second it is based on a class antagonism, and at the final, third level it witnesses the antagonism between different modes of production. After words, I move on to the Jameson’s critique of postmodernism. Postmodernism has difficulties with a signification of the present mode of production, because late capitalism successfully removed the remains of the other modes of production. Lacking the active engagement with the past, postmodern texts are not able to constitute coherent representation of the present for which Jameson has come up with the term cognitive map. Paradigmatic example of this impossibility of cognitive mapping in postmodernism is nostalgia film. Jameson gives the best explanation of nostalgia film in his analysis of Stanley Kubric’s film The Shining. He concludes that political unconscious of nostalgia film is desire for cognitive mapping in the form of clear class hierarchy that would enable construction of a new collective utopian program.

    This document reports data collected as part of the Ecological Monitoring Program (EMP) at the Waste Isolation Pilot Plant near Carlsbad, New Mexico, for Calendar Year 1987. Also included are data from the last quarter (October through December) of 1986. This report divides data collection activities into two parts. Part A covers general environmental monitoring which includes meteorology, aerial photography, air quality monitoring, water quality monitoring, and wildlife population surveillance. Part B focuses on the special studies being performed to evaluate the impacts of salt dispersal from the site on the surrounding ecosystem. The fourth year of salt impact monitoring was completed in 1987. These studies involve the monitoring of soil chemistry, soil microbiota, and vegetation in permanent study plots. None of the findings indicate that the WIPP project is adversely impacting environmental quality at the site. As in 1986, breeding bird censuses completed this year indicate changes in the local bird fauna associated with the WIPP site. The decline in small mammal populations noted in the 1986 census is still evident in the 1987 data; however, populations are showing signs of recovery. There is no indication that this decline is related to WIPP activities. Rather, the evidence indicates that natural population fluctuations may be common in this ecosystem. The salt impact studies continue to reveal some short-range transport of salt dust from the saltpiles. This material accumulates at or near the soil surface during the dry seasons in areas near the saltpiles, but is flushed deeper into the soil during the rainy season. Microbial activity does not appear to be affected by this salt importation. Vegetation coverage and density data from 1987 also do not show any detrimental effect associated with aerial dispersal of salt.

    The k o -standardization method of neutron activation analysis (k o -NAA) has recently been developed on Dalat research reactor. However, in order to apply the k o -NAA technique for practical research objects, it is necessary to establish different experimental procedures for each object. This work is aiming at establishing such a k o -NAA procedure on Dalat research reactor for human hair samples to solve the environmental pollution study prob;em. Therefore, the sample collection and preparation, irradiation, gamma-ray spectrum measurement and data processing, as well as quality assurance and quality control of the k o -NAA procedure for human hair samples have been assessed by comparing with elemental concentrations in terms of the experimental to certified values ratio and U-score. The experimental results showed that the k o -NAA for multi-element in human hair sample analysis is able to apply on Dalat research reactor with a rather good analytical quality. (author)

    The turbofan engines for private aircrafts have come to have a high bypass ratio because a performance improvement is always requested. Because a turbofan engine is always required for a thrust reinforcement to correspond the stretch and weight increase of a fuselage after acquiring a type approval, making them a series to cover a certain thrust range becomes necessary. The concrete methods to reinforce a thrust are being achieved by an increase of fan diameter, a partial modification of high pressure compressor, a temperature rise of high pressure turbine inlet, a stage number increase of low pressure turbine, and a combination of these items just mentioned above. The PW 4000 series, CF6 series and RB211 series currently under production are being reinforced in a thrust by these methods. In this paper, as the representatives of some turbofan engines incorporating the most advanced technologies, as for 3 kinds of the large scale turbofan engine presently under development for the B777, namely GE90, PW4084, and TRENT800, their distinctive futures are summarized. 25 figs., 1 tab.

    Full Text Available The aim was to investigate risk factors for falls in elderly people living in residential nursing homes. An observational, prospective, multicentre study was conducted between March 2010 and March 2011 investigating falls in elderly residents living in residential nursing homes (4 Italian¸ 4 French and 5 German nursing homes. A number of risk factors were assessed as well as details of the fall (dynamics, reasons, location and time of occurrence. Differences were observed between the countries related to different nursing practices. Fallers comprised 36.5% of all residents and approximately 40% were injured as a consequence. Six logistic regression models were created to assess which fallrelated variables had the most impact, and showed subjects with faecal incontinence had a lower risk of falling, while subjects afflicted with dementia and visual impairment showed an increased risk of falling. Higher Tinetti scores were found to be related to an increased fall risk. Falls in the elderly occur due to complex interactions between demographic, physical, behavioural and environmental risk factors. Differences between countries in fall rates were seen, probably due to different medical practices, use of aids and restraints, and characteristics of the populations (i.e. the Italian residents tended to be more cognitively impaired and more impaired in balance and gait compared to the French and German residents. There was evidence that subjects with a better clinical status fall more frequently, whereas non-fallers had a worse clinical status and therefore tended to be more bedridden.

The basin is surrounded by mountains on three sides and faces the Yangtze on one side, whereas the plains formed by the lake and the rivers flowing in extends in the center of the basin. The plains around the lake has the city of Nanchang, the capital of the province, the city of Jiujiang (both cities have a population of about 4 million, respectively), and four other cities with a size of one million people including Jingdezhen. Water supply system in the basin is used in a 37% area of the urban areas, and no sewage facilities of whatsoever are available as of 1991. The lake has COD of about 3 mg{times}1/l. No severe pollution by organic matters is seen. While the T-P concentration is at a high level, PO4-P is low. Majority of phosphorus flowing into the basin exists in the form trapped in soil particles. In order to maintain the current water quality in the future, waste water treatment is required in the basin. Construction of an oxidation pond in the vast land exposed during the drought period is a measure that can be tackled relatively easily. 1 fig., 4 tabs.

    Full Text Available The purpose of this study is to get an alternative bioprocess technology of bioethanolproduction from cassava using the technique of co-cultured “tape” yeast and Saccharomycescerevisiae. The study was designed with a completely randomized design experiment using 7level of co-culture techniques. All treatment was repeated 2 times. The parameters measuredwere the final pH, percentage of substrate consumption, ethanol concentration and fermentationefficiency. Using coculture technique in the process of fermentation to producebioethanol gives better results than the use of a single culture or pure culture of “tape”yeast and S. cerevisiae. Coculture technique that gives the best results is the treatmentof fermentation process by giving the “tape” yeast to the first day and followed bygiving culture S. cerevisiae for the next two days. This treatment has a final pH 4:05,the percentage substrate or glucose consumption of 82.92%, the concentration ethanolof 11.0% (w/v and the fermentation efficiency of 52.94%.

    Full Text Available The sojourn of Alexandra Kollontai in Sweden and Denmark (IX 1914–I 1915The aim of this article is to present the activites undertaken by Alexandra Kollontai during her stay in Sweden in 1914. Alexandra was a famous socialist activist at the time, and as a consequence of her activity had to flee Russia in 1908. For the following eight years, she remained in exile. She traveled throughout Europe, but collaborated most closely the with German Social Democrats party. After the I World War began, Kollontai – along with her son, Michael – was arrested. Thanks to an intervention of influential German politicians, both of them were released from jail. Shaken, she broke up her ties with the German socialist movement. Alone, Kollontai traveled to Sweden in September 1914, and moved for good to Stockholm. During the sojourn in Sweden, Kollontai was in touch with one of the most prominent local socialist activists, Hjalmar Branting, and took an active part in the Swedish socialist movement. During her short-term stay in Norway, Kollontai was not formally a supporter of the Bolshevik proposition, but she still wrote letters to Lenin. She also had a love affair with a Bolshevik comrade, Alexander Shliapnikov. The Swedish police arrested Kollontai for participation in anti-military propaganda activities. She was exiled from the country in November 1914, to Copenhagen. Also there, Kollontai managed to establish close relationship with the Bolsheviks. Hereafter, she has played a crucial role in the re-opening of the northern smuggling route.

    In order to strengthen materials, the improvement of residual stress in stainless steel by using a cavitating jet was investigated. In case of cavitating jet, the cavitation intensity can be controlled by hydraulic parameters such as upstream pressure and downstream pressure. In general, cavitation produces damage on hydraulic machinery. However, at the initial stage of cavitation erosion process, plastic deformation takes place on the material surface, then it is possible to do peening without damage considering the cavitation intensity and the exposure time. In order to evidence the suitable condition on the improvement of residual stress by the cavitating jet, the residual stress in SUS304 and SUS316 was examined. The three normal stresses in different directions were measured by X-ray diffraction method, then the principal stresses were calculated. Both principal stresses were changed from tension to compression within 10 seconds by the cavitating jet. The compressive stress resulted by the cavitating jet was saturated after a certain time. It was concluded that the cavitating jet improved the residual stress in stainless steel SUS316 as well as SUS304. 24 refs., 9 figs.

    Meat consumption has been shown to be associated with cardiovascular disease (CVD) risk in Western societies; however, epidemiological data are limited on the Korean population. Therefore, we examined the associations between unprocessed meat consumption and CVD incidence in Korea. Data were derived from the Ansung-Ansan cohort (2001–2012), including 9370 adults (40–69 years) without CVD or cancer at baseline. Total unprocessed meat consumption was estimated as the sum of unprocessed red meat (beef, pork, and organ meat) and poultry consumption. In the fully adjusted Cox regression model, the relative risks of CVD across increasing quintiles of total unprocessed meat intake were 1.0 (reference), 0.72 (95% confidence interval (CI): 0.55, 0.95), 0.57 (95% CI: 0.42, 0.78), 0.69 (95% CI: 0.51, 0.95), and 0.69 (95% CI: 0.48, 0.97), but no significant linear trend was detected (p for trend = 0.14). Frequent poultry consumption was significantly associated with a decreased CVD risk; this association showed a dose-response relationship (p for trend = 0.04). This study showed that a moderate intake of total unprocessed meat was inversely associated with CVD risk. A significant inverse association between poultry consumption and incident CVD was observed in Korean adults, requiring further confirmation in other populations. PMID:28505126

    Full Text Available The ideologist of the Yugoslav Communist Party, perceived the socialism as constant struggle and one of the crucial battles for building of the new society. The regulary organized Youth Working Actions were of the special importance as places where this struggle could be developed, organized and led. The main method was the “Socialist Competition”. It has the emphasized ideological dimension, since the hard physical labor was perceived as the main tool for building of the strong and conscious personalities of the socialist men and women. Inspiration for the established practice of the “Socialist Competition” was discovered in the theoretical works of the classics of the Marxism: Lenin and Stalin. The Competition propaganda was very aggressive. It was constantly announced in the news and the radio program which was listened in the Working Actions compounds. Those announcements were actually paroles fitted with the graphic images of the work statistics, coupled with the portrait of the Yugoslav Communist Party leaders and scenes of the youth in work. The authors reviles the “other” side of the Competitions, showing the young party cadres struggling for easy climbing within the hierarchy, problems of the quality of the works and buildings performed, as well as the injuries and some fatalities in this process, which remained hidden from the propaganda efforts. But besides such problems, in general, the Socialist Competition helped the mobilizing of the youth for public works, among many resulted in important building and infrastructure works.

    Full Text Available The most threatened part of environment is air and its pollution increases rapidly. In the local rate, the weight of air pollution increases by reason of a more intensive influence on the human population. The problem is significant mostly in urban areas, places with the biggest concentration of peoples, industry and transport. The greatest producers of air pollution are various parts of industry, heat production and traffic. For a complex valuation, the influence of particular parts of industry is needed to know the sources of air pollution in the specific area. Only with a knowledge, it is possible to evaluate a spotted area in terms of air quality.

    Contributions to Λ c + → φΣ, φΛ and p anti K o from excited states are considered. The calculations are performed within the MIT-bag model and a Heavy Quark bag model. Because the mass of Λ c + is rather big compared to the strange baryons, excited baryon states with mass close to that of Λ c + in some cases give significant pole contributions to the decay amplitudes of Λ c + . 20 refs., 3 tabs

    With the aim of contributing to the development of optical elements, devices, sensors, high performance catalysts, etc., R and D was conducted on fundamental technologies for creating materials using harmonized molecular actions, and the fiscal 1999 results were reported. In the R and D of self-assembled molecular film materials, an electric-field sensitive self-assembled molecular film was experimentally manufactured, as were self-assembling electroluminescent and lyotropic liquid crystal pigmentary film materials. In the R and D of mesophase materials, for rod-like liquid crystal systems, a material was successfully developed possessing a transparency of 90% in the visible region accompanied with an optical phase difference of 4.0 microns. For disk-like liquid crystal systems, a diminishing tendency of obtainable photoelectric current was confirmed even with a small change in the orientation after photopolymerization. In the R and D of microporous materials, synthesis was performed for system-controlled metallosilicates and shape-controlled microporous materials. Further, structural correlation was examined for organic templates and microporous materials. (NEDO)

    Creation of new functional inorganic materials using micro-gravity environment was studied. Observation of an electrode interface phenomenon under micro-gravity clarified that time variation in interference fringe is dependent on current density and electrode thickness in ground experiment, while it is dependent on not electrode thickness but current density under micro-gravity. In fabrication of glass fine particles under micro-gravity, true spherical glass fine particles of 4-7{mu}m in size were obtained corresponding to a charge of 40mg by evaporation and solidification of sodium tellurate glass as raw material under micro-gravity. In fabrication of non-harmonic Pb-Zn system alloy, the homogeneous alloy texture of 5{mu}m level was observed which has never been observed in previous metal phase diagrams by fusion of 80atom%Pb-20atom%Zn mixture under micro-gravity and quenching from 500degC.

    The paper investigated/studied `space light modulation materials,` `dynamic hologram/memory materials,` `optical waveguide path materials,` etc. which become key materials in the high speed two dimensional processing. As to electrooptical materials proposed in this investigational study, the external electric field and the electric charges generated make quality of molecules themselves directly change to memory strong/weak signals of light. Therefore, the response velocity becomes less than a millionth of that of the liquid crystal display, and high speed which is needed for realtime moving image processing is anticipated. Hologram includes the phase information in addition to information on light strength. Therefore, it is a large capacity record medium and at the same time a record medium which can read/write two dimensional information as it is. With optical fiber, images cannot be transmitted as they are. Light waveguide path materials are those that accumulate roles of mirror and lens in a sheet of the material and construct a system which is strong in vibration, as optical parts connecting among materials for two dimensional data processing. 273 refs., 107 figs., 17 tabs.

    Investigations were conducted by simulation of breakage of inhomogeneous materials (rock) attributable to detonative loading, which simulation used the Days-2 Code. During the simulation, one-free-face blastings were used for testing a homogeneous structure, horizontal 2-layer structure, and horizontal 3-layer structure. Property values were assigned to the rocks on the assumption that they were sedimentary rocks such as sandstone or mudstone or hard rocks such as granite. As the result, it was found that a detonative loading resulted in shear failure in a sphere near the focus that was followed by radially developed cracks due to tension breakage, that more area is damaged in a soft rock than in a hard rock, that cracks due to breakage are produced by the overlapping of waves directly from the focus and those reflected from the free face in case of one-free-face blastings, that such cracks propagated along the soft rock layer in case there is a soft rock layer in a hard rock, but that breakage does not extend beyond the soft rock layer. 6 refs., 6 figs., 1 tab.

    Activities were performed with an objective to establish fundamental technologies related to photoreactive materials capable of ultra-high density and high resolution indication by controlling structures and assemblies of molecules by using light. The activities were taken in the four fields of elucidation of photoreactive mechanisms and fundamental properties, development of the materials, material processing and constituting technologies, and evaluation technologies. Specifically speaking, the activities were developed on the multiplexing technology applicable to ultra-high density recording, sensitivity responsiveness, and material stability in photochromic materials and photochemical hole burning (PHB) materials. For the photochromic materials, development was performed on photochromic materials to form associations, and on a thin film forming technology by means of the organic molecular beam epitaxial process. For the PHB materials, research was implemented on use of the materials at elevated temperatures, development was made on quinone-based materials, research on enhancement of multiplexity, development on porphyrine-based materials, and research on the organizing technology. In the research of the use at elevated temperatures, development was progressed on a material that can retain under the liquefied nitrogen temperature the status of wavelength multiplexed recording that has been formed under the liquefied helium temperature.

    The fiscal 1998-2000 results of efforts to develop cluster diamond (CD)-diffused solid lubricant composite materials expected to exhibit excellent lubrication are stated. Since friction greatly affects machine life and energy efficiency, friction reduction is an important task. Very hard and microscopic CD was utilized for the achievement of a friction coefficient of 0.08. A manufacturing technology for molds 10nm or smaller was developed, which enabled the development of a gear not larger than 8mm. The success will enable the operation of micromachines in the absence of lubrication which is impossible at present. A CD-aided functional layer creation technology was also developed. It is expected that the development and practical application of micromechanisms will make rapid progress in the 21st century. Much is expected from the creation, and goods with the achievement applied thereto, of advanced technologies whereinto non-lubrication, functional layer creation, and excellent heat conductivity are incorporated. It is quite significant that, since CD is available in any field as far as light-load low-speed sliding conditions are satisfied, sliding parts will be improved and service life will be prolonged.

    Arc synthesis method, which is now the center for the synthesis of new carbon compounds such as carbon nanocapsules and carbon nanotubes, is introduced together with its current status. Many new carbon compounds are synthesized by DC arc discharge heating method (arc discharge method) in which a graphite bar is used as the electrode. C70 and higher order fullerenes having larger carbon numbers are found one after another in the soot produced by the arc discharge method, and the structures of C76, C78, C84, C90, C94, and others have been clarified. It is considered in the arc discharge method that the processes of a large amount of carbon evaporation by high temperature and the succeeding quenching cause to produce various kinds of new carbon compounds. In connection with other synthesis methods, synthesis of fullerenes by incomplete combustion, synthesis of nanotubes by the vapor phase thermal decomposition method, and the synthesis of nanotubes using casting molds are discussed. 24 refs., 6 figs.

    A technique is discovered for improving on the baking properties of cerium oxide which is one of the solid electrolytic materials for SOFC (solid oxide fuel cell). Cerium oxide, samarium oxide, and gallium oxide are weighed, each to the specified element ratio. The element ratio of cerium is fixed at 0.8 against the other elements except oxygen, and the element ratios of samarium or gallium are caused to change. Specimens containing gallium are designated as CSGa, those not containing as SDC. SDC baked at 1600degC and CSGa (1%) baked at 1450degC are similar to each other in terms of average grain diameter. Specimens with gallium added thereto can be baked at temperatures that are lower than these by approximately 150degC. The conductivity of CSGa (0.2%) baked at 1500degC is higher than that of SDC baked at the same temperature, and is similar to that of SDC baked at 1600degC. Baking is enhanced by the addition of 0.2% gallium. In the domain where more than 1% of gallium is in presence, conductivity lowers with an increase in the amount of gallium added. The conductivity of CSGa (1%) baked at 1450degC is similar to that of SDC baked at 1600degC. 4 figs., 1 tab.

    In the paradigm that propelled polymer chemistry, there are involved the establishment of polymer concept, engineering plastics, regulation of higher ordered structure, and precision polymerization. The first two produced the polymer chemistry era in the 20th century. The regulation of higher ordered structure and the precision polymerization are the fundamental technologies supporting the polymer chemistry of the 21st century. The precision polymerization is a technology for regulating the stereospecificity, sequential structure, and molecular weight of polymers by regulating atoms and molecules and is referred to the following important techniques to be concrete. In the precision addition polymerization, stereospecific regulation and purification of active site to give living polymers are required while, in the precision condensation polymerization, regulation of condensation probability process to be secondary Marcov chain is necessary, as is the establishment of non-defect condensation condition avoiding high temperature deterioration and the like. In the biomimetic precision polymerization, key issues are the method of incorporating molecular recognition control and sequential structure control by living organs into an industrial process. If the higher ordered structure can be regulated by the precision polymerization, it is possible to obtain numerous high performance/high functional materials such as superconductors. (NEDO)

    A discussion was given on the fundamental properties of mortar made from cement mixed with silica fume. Four kinds of silica fumes with different particle size distributions were used. The following results were obtained: distribution of pores in mortar admixed with silica fume shifts to the smaller radius side; while the admixture increases the compression strength in mortar, the increasing trend varies depending on the kinds of silica fumes; this is thought to be caused from the difference in pozzolan activity between silica fumes; and the strength increase is caused by densification of the structure due to the pozzolan reaction that is generated after hydration, or in other words, decrease in the pore volume. The applicability of the mortar was investigated as a filling mortar to fill up clearances between wastes. It was found that the filling performance can be controlled by mixing silica fume at an adequate level and adjusting the viscosity. The diffusion coefficient for the admixed concrete is smaller by 30% to one digit than that for the ordinary concrete. High-performance water stopping concrete of 0.11 {times} 10{sup 4}cm {sup 2}/s at maximum was obtained. The concrete can be regarded as a material having superb filling and water stopping performances. 6 refs., 4 figs., 5 tabs.

    The paper stated mostly topics from special lectures. Composite materials have a lot of potentialities, and there are larger expectations in flexible and high-strength soft composites rather than the conventional high rigidity ones. As to micro-machines, the problems are on mechanical property of the element, environment/friction/fracture/life, etc. and the evaluation method of the characteristics was studied. Concerning the research and development of the intellectual structure system, the introductive study has entered the second year. Ultimately, structures have functions similar to those of the living organism had, and conduct self-diagnosis, self-repair and autonomous-response. Railroad structures receive regular inspections according to the rule, and a half of the objects for the inspection are cracks, unbonding and weathering of concrete. With the Hanshin Awaji great earthquake especially, the anti-earthquake reinforcement has been expedited. In various kinds of materials, the finer the crystal particle becomes, the greater the high temperature deforming ability becomes. When the particle size is below the critical particle size, it shows superplasticity. The study is advancing. As to high density secondary batteries, introduced especially were Ni-hydrogen batteries and Li batteries.

    Study was made on improvement of the strength of silica aerogel as transparent insulating material. Silica aerogel is a low-density porous material with high heat insulation and transparency. To develop a insulating material with high transparency, monolithic silica aerogel was studied. For direct use of it for windows, its strength improvement was attempted. The aerogel was prepared by supercritical drying (alcohol or CO2) of silica wet gel obtained by hydrolysis and condensation of silicon alkoxide solution. To prepare the aerogel bonded on plate glass for strength improvement, the aerogel was bonded to alkoxide by exposing active silanol radical through F-etching of plate glass surface. However, to obtain the practical large-area bonded aerogel, shrinkage control of the aerogel in supercritical drying was necessary. Addition of Laponite into a silica network for strength improvement by polymer increased the bending strength by 50%. Although some reduction of its transparency was observed because of clouding, its heat insulation was stable. Further strength improvement is necessary for its practical use. 5 figs., 1 tab.

    Experiments were conducted under microgravity for findings on the creation of microspheric photonic materials which are high in sphericity. The experiments were carried out at the fall type microgravity facility of Japan Microgravity Center (JAMIC). In the experiments on the ground surface and under microgravity, glass specimens of 3BaO-97B{sub 2}O{sub 3} mol%, 4BaO-96B{sub 2}O{sub 3} mol%, and 2SrO-98B{sub 2}O{sub 3} mol% were tested. They were heated, melted, and cooled for the on-site observation of phase splitting in them. It was found as the result that, in the case of specimen 3BaO-97B{sub 2}O{sub 3}, the phase splitting start under microgravity was similar to that on the ground surface while the nucleation velocity was lower under microgravity. Specimen 2SrO-98B{sub 2}O{sub 3} mol% exhibited an approximately 0.5-second delay in its phase splitting start under microgravity as compared with its ground surface behavior. As for the nucleation velocity under microgravity, the value was same as that on the ground surface in the first half but, in the second half, it was lower than that on the ground surface. The said approximately 0.5-second delay in the phase splitting start was, when the cooling rate was taken into consideration, attributed to an approximately 6.5 degrees C fall in the phase splitting start temperature, and this suggested that phase splitting was suppressed under microgravity.

    A radiation thermometer was applied to the measurement and analysis of radiation temperature of the material surface. In this paper, the characteristics of the radiation temperature and the radiosity coefficient of gray body materials are investigatied. An infrared radiometer was used, which detects radiation energy in the region between 8 and 13{mu}m of wavelength. This infared radiometer has a Hg-Cd-Te photon radiation sensor. The variation of emissivity was measured for the four kinds of non-metalic materials, i.e., graphite, carbon fiber composite, Si-SiC ceramic, and black paint spread on an aluminum plate. As a result, the relationship between material temperature and radiation energy was made clear. Furthermore, the space-dependent variation of the radiation temperature and the radiosity coefficient was derived from the two-dimensional CRT image of the infrared radiometer. Consequently, the emmisivity variation gave a maximum for the carbon fiber composite surface rich in irregularity, and decreased in the order of graphite, Si-SiC, and black paint. 7 refs., 15 figs.

    The secondary dental caries easily occur by breeding of bacteria in cavities between living body and composite resin, false tooth or root of tailored tooth as tooth repairing materials. The antibacteria activity of tailored dental materials was thus studied by implanting Ag ion. The antibacteria effect with time after culture of caries bacteria was studied by implanting Ag ion into SiO2 powder, PMMA samples and Ti alloy samples at 20 and 200keV in energy of ion. In addition, the antibacteria activity of SiO2 powder as composite material was found at 25keV which was previously effective for the antibacteria activity. This SiO2 filler (Ag{sup +} filler) showed the antibacteria activity on every bacteria sample after 2h, and in particular, could kill all of 3 kinds of bacteria obtained from a composite resin surface after 12h. The number of living S. salivarius was reduced by half after 12h. The application of the composite resin filler implanted with Ag{sup +} is significant to prevent recurrence of caries. 5 refs., 27 figs., 7 tabs.

Used for the pNA{center_dot}Bronsted acid composite are HBr, HCl, HNO3, and H2SO4. The pNA that has a center of symmetry in the crystalline structure and does not generate the second harmonics shows SHG when it is formed into a composite with HBr. No SHG is recognized in other acid composites. This difference is due to the difference in the crystalline structure. The SHG activity was generated when pNA is loaded onto alumina and silica as solid oxides. When zeolites are used as carriers, no SHG was observed. A composite of pNA{center_dot}AlCl3 has high SHG intensity, which reached a maximum when the pNA/AlCl3 ratio was two. This composite showed four new peaks that belong to the SHG activity phase. 8 refs., 2 figs., 2 tabs.

    Development of new materials with both thermal resistance and thermal shock resistance was studied on the basis of symmetric ceramics/metal/ceramics gradient composition. Al2O3/TiC/Ni/TiC/Al2O3 was used as material model of basic composition, and the system was selected where WC-Co system alloy hard particles were dispersed into the Al2O3 ceramic surface layer. The layered material was sintered in N2 gas atmosphere by SHS/HIP method using exothermic caused by nitriding reaction. Since cracks were generated in some specimens of 5-layer structure, improved specimens of 7-layer structure were prepared. To examine the effect of a particle size on toughness, WC-Co system alloy specimens with different particle sizes were also prepared. As a result, no cracks were found, and residual stress and fracture toughness were affected by particle size. In addition, the following were studied: technique of mass production, observation of fine structures, analysis of thermal stress, thermal shock resistance, and friction and abrasion characteristics. 13 refs., 65 figs., 15 tabs.

    Full Text Available Changes in the language situation of Vershina near Irkutsk in the conditions of Polish-Russian bilingualism Vershina was founded in 1910 by Polish voluntary settlers from Lesser Poland. There are three main periods in Vershina’s history, with different social conditions affecting the language choice. During its first three decades the settlers preserved Polish language (a mixture of dialects from their regions of origin, traditions and the Roman Catholic religion. The effects of the Revolution of 1917 and political changes came to a village in taiga only in the late 1930’s. Vershina lost its former ethnocultural homogeneity because of Russian and Buryat workers in the local kolkhoz. It was the beginning of the increasing role of Russian language in the village’s life. The process of intensive sovietization as well as heterogeneous marriages affected language choice in many domains. In the late 1980’s the inhabitants of Vershina regained their minority rights: they can pray in their own church, learn Polish in a local school and found cultural organisations. However, during the years of communism, the language situation changed irreversibly. There are some factors which may hinder the increasing domination of Russian language, such as activity of local Polish organisation, Roman Catholic parish and folk group “Jazhumbek” but their influence is limited.   Изменения языковой ситуации в Вершине Иркутской области в условиях польско-русского билингвизма  Вершина была основана в 1910 г. польскими добровольными переселенцами из Малой Польши. В истории деревни мы можем выделить три основных периода, характеризирующиеся разными социальными условиями, влияющими на выбор языка. За первые три десятилетия жители Вершины сохраняли польский язык (смесь диалектов из их родных регионов, традиции и римско-католическое вероисповедание. Вершининцы (как они сами называют себя почувствовали последствия Октябрьской революции и политические изменения только в конце 30-х гг. ХХ века. Вершина потеряла прежнюю этнокультурную гомогенность из-за присоединения к местному колхозу бурятских и русских хуторов. Роль русского языка в жизни деревни стала постепенно увеличиваться. Процесс интенсивной советизации, а также смешанные браки повлияли на выбор языка во многих сферах жизни. В конце 80-х гг. ХХ века жителям Вершины вернули их права меньшинства: они могут молиться в своем костеле, учиться польскому языку в местной школе и создавать организации, но время коммунизма неотвратимо изменило языковую ситуацию общины. Увеличивающееся преобладание русского языка может остановить лишь активная деятельность местной польской организации, римско-католического прихода и фольклорного ансамбля «Яжумбек» („Рябчик”, но их влияние ограничено.

The consumer basket belongs among important economic characteristics, which determine the economic level of each country. The contribution of the article consists in identification of changes in the structure of consumer basket related to two chosen countries. Methodology/methods: The development of the structure of consumer basket of average household in two countries during the period from 2004 to 2014 is analysed. The structure is expressed by means of expenditure shares, while the development by means of trend models. Coefficient of determination and correlation coefficient are used within choosing the appropriate trend function. Scientific aim: The aim of this article is to assess the development of the structure of consumer basket of average household in the Czech Republic and Slovak Republic during the period from 2004 to 2014 by each country including mutual comparison. In detail, the development of consumer expenditure groups of consumer basket is assessed. Findings: Expenditure shares are found to be enough volatile in time. The highest coefficients of determination are found just in case of quadratic function. Mostly, the found correlation in trend model is strong. Incomes and expenditures mostly increase in time. Based on the 2004 and 2012 comparison, the percentage rates expressing, how much incomes exceed expenditures increase about 11% by the household in the Slovak Republic, however the ones increase only about 3% by the household in the Czech Republic. Conclusions: The structure of consumer basket of household and the structure of household expenditures in the Slovak Republic differs from the ones in the Czech Republic. Both differences and common features are found within the development of indicators. Common features could be caused by the fact, that these two countries constituted only one country till 1. 1. 1993.

    Electron paramagnetic resonance (EPR) studies have been investigated on Cu2+ ion incorporated into the single crystals of potassium succinate-succinic acid (KSSA) at room temperature. Two magnetically in-equivalent Cu2+ sites in the lattice are identified, among them site I has been reported. The spin Hamiltonian parameters are determined with the fitting of spectra to rhombic symmetry crystalline field. The co-ordination of the Cu2+ ion in this molecule is a distorted dodecahedron. From the calculated gxx, gyy, gzz and Axx, Ayy, Azz and their directional cosines values, location of site I impurity ion Cu2+ could be identified as a substituitional one. Also the ground state wave function of the impurity ion was found to be d2z.

    Alloy elements are added to compensate for reduction in hardenability of high chromium cast iron as a result of destabilization heat treatment. With the purpose of investigating the influence of the added elements, this paper describes investigations made on effects of Mo and destabilization heat treatment conditions on martensite transformation , eutectoid transformation and base hardness, using Fe-Cr-C-based alloy containing C at 1.6-3.6%, and Cr at 6.6-26%. The main results obtained are as follows: Mo and Cr had the distribution coefficient for initial crystal austenite is smaller than one and were microscopically segregated in the dendrite base; the solute element distribution in the base is homogenized as a result of the long-time destabilization heat treatment while the Cr and C concentrations reduce largely, and the Mo concentration increases slightly; Mo has little influence on the Ms point, and reduces with the smaller the Cr/C ratio and the higher the retention temperature; and the base hardness corresponds well to a CCT diagram. 14 refs., 11 figs., 1 tab.

    A new corrosion resistant steel was developed as a metal system lining material to prevent sulfuric acid dew point corrosion in smokestacks and ducts. SO3 in stack gas turns to sulfuric acid as a result of reacting with coexistent moisture in non-steady conditions during boiler actuation and shutdown when smokestack walls have low temperatures. When sulfuric acid thus generated contacts with metallic materials at temperatures lower than the sulfuric acid dew point temperature, sulfuric acid dew point corrosion occurs. During boiler steady operation, localized corrosion develops at clearance between salt deposits and the metallic materials. In order to improve the corrosion resistance, Mo, Cu and N were added in a reasonable range of amount. Entire surface corrosion resistance and local corrosion resistance were experimented in aqueous solutions simulating the smokestack environments to derive relational formulas with steel compositions. The new corrosion resistant steel met the the entire surface and local corrosion resistance requirements and was found economical. Low torsional velocity tensile and U-bend tests proved the steel satisfying the stress corrosion resistance requirement. Semi-automatic CO2 welding and shielded are welding provided good workability with no cracking, and impact strength and corrosion resistance in joints equivalent to those in the base material. 3 refs., 4 figs., 4 tabs.

    The objectives of this study were to develop a food-frequency questionnaire (FFQ) for Vietnamese female immigrants in Korea and to evaluate the validity of the FFQ. A total of 80 food items were selected in developing the FFQ according to consumption frequency, the contribution of energy and other nutrients, and the cooking methods based on one-day 24 hour recall (24HR) from 918 Vietnamese female immigrants between November 2006 and November 2007. The FFQ was validated by comparison with 24HR of 425 Vietnamese female immigrants between November 2008 and August 2009. The absolute nutrient intake calculated from the FFQ was higher than that estimated by 24HR for most nutrients. The correlation coefficients between 24HR and FFQ ranged from 0.10 (vitamin C) - 0.36 (energy) for crude intake, 0.05 (vitamin E) - 0.32 (calcium) for per 1000 kcal, and 0.08 (zinc) - 0.34 (calcium) for energy-adjusted, respectively. More than 70% of subjects were classified into the same or adjacent agreement groups for nutrients other than fiber, sodium, vitamin A, vitamin C, and vitamin E, while less than 10% of subjects were classified into complete disagreement groups. We conclude that the FFQ appears to be an acceptable tool for estimating nutrient intake and dietary patterns of Vietnamese female immigrants in Korea. Future studies to validate the FFQ using various biomarkers or other dietary assessment methods are needed.

Residents who lived with smokers were excluded. Urinary cotinine concentration was used as a biomarker for SHS exposure. The factors associated with urinary cotinine levels in non-smoking residents were determined using multivariate regression analysis. Results Urinary cotinine was detected in 88 % of the 814 non-smoking residents of smoke-free homes. The urinary cotinine concentrations of residents living in attached [1.18 ng/mg creatinine (Cr] and detached housing (1.23 ng/mg Cr were significantly higher than those of residents who lived in apartments (0.69 ng/mg Cr. Urinary cotinine concentrations were significantly higher in residents who were men, those with a household income ≤1000 USD/month, those who were former smokers with >1 year and ≤1 year of not smoking, and those who experienced SHS odor every day. In the multivariate regression analysis, housing type, sex, former smoking status, and frequency of experiencing SHS odor were associated with urinary cotinine concentrations (R 2 = 0.14. Conclusions The majority of non-smoking residents of smoke-free homes had detectable urinary cotinine. Housing type, sex, former smoking status, and frequency of experiencing SHS odor were predictors for urinary cotinine concentrations in the study participants.

    Full Text Available Bosnia and Herzegovina together with Serbia shows the poor economic performance compared to neighbor countries, while the European average remains a remote and largely unattainable category. The reasons for this unsatisfactory situation are many, and this paper aims to highlight the entrepreneurial aspect of the economic dynamics of these countries compared to the world, European and regional average. We will use comparative, statistical, dynamical and cognitive analysis and synthesis in order to get better insight into the causes of our current situation, as well as recognizing the potential comparative advantages. Through presentation of the BiH and Serbia position in the Reports of the World Economic Forum in relation to the weighted averages of the world, Europe and the region, and further through the analysis of the basic parameters of competitiveness and detailed analysis of business environment indicators we will reach important conclusions about the most important shortcomings and potential advantages of entrepreneurship in BiH and Serbia. These results should be kept in mind while creating future economic measures, and they have considerable usable value for current and future entrepreneurs.

    BACKGROUND/OBJECTIVES This study was conducted to compare the overall changes in dietary intake and metabolic syndrome risk parameters in Vietnamese marriage-based female immigrants over time. SUBJECTS/METHODS The subjects of this study were 581 Vietnamese marriage-based female immigrants, who were recruited from local clinical centers in Korea. Baseline data were collected from 2006-2011 and the follow-up data were collected from 2012-2014. Dietary food intake was assessed by a 1-day 24-hour recall method. RESULTS Compared to the baseline, the mean body weight, body mass index, waist circumference, high density lipoprotein (HDL)-cholesterol, systolic blood pressure and diastolic blood pressure increased while the fasting blood sugar, triglycerides and low density lipoprotein-cholesterol decreased at follow-up. The total consumption of foods such as vegetables/fruits/seaweeds/mushrooms, oil and fat, and eggs decreased during the follow-up period, whereas the consumption of sugars, beverages and meats increased. Partial correlation between the rate of change [(Follow-up - Baseline) / Baseline × 100] in metabolic syndrome risk parameters and food intake after controlling for confounding factors showed that the waist circumference was positively correlated with either the total plant food intake (r = 0.1042, P = 0.0129) or the total food intake (r = 0.0880, P = 0.0359). The plasma levels of total cholesterol (r = -0.1918, P = 0.0289) and HDL-cholesterol (r = -0.1424, P = 0.0007) were negatively correlated with the percentage of total intake from plant food, and HDL-cholesterol levels were positively correlated with the intake of total animal food (r = 0.0980, P = 0.0217). The serum C-reactive protein levels were positively correlated with the total intake of animal food (r = 0.2374, P < 0.0001) or the percentage of total intake from animal food (r = 0.1346, P = 0.0016). CONCLUSIONS These results suggest that the change rate of dietary intake such as total plant food or animal food is associated with the change rates of metabolic syndrome risk parameters.

    Full Text Available Thanks to Buddhist contexts, present in S. Beckett's two long plays (The Endgame and The Happy Days we understand that death, signifying the ultimate Nothingness and Emptiness appears to be the change of the perceiving substance, which getting rid of the body, is joined with the nonbodily content of the things. Beckett's doxology of the light makes it that since Life is compared to the flame, Death depicts its extinguishing, but at the same time the value of eschatological hope is expressed through Buddhist motifs (karma of the Yoga, little Buddha, nirvana, the wheel of Samsara and the like. Death is for Winnie, Hamm and Clove an internal act of transgression, touching directly the dying person, but at the same time the heroes of Beckett's plays transfer their feeling connected .with dying to the external observer (the spectator. And so Beckett achieved the dimension of the most important function of the theatre of „participation" and „initiation". Recognising Buddhist contexts in Beckett's plays, we accept Death as one of the stages of the biological cycle - being a peculiar kind of repayment of a debt to nature.

  18. Impairment of enzymatic antioxidant defenses is associated with bilirubin-induced neuronal cell death in the cerebellum of Ugt1 KO mice

    Severe hyperbilirubinemia is toxic during central nervous system development. Prolonged and uncontrolled high levels of unconjugated bilirubin lead to bilirubin-induced encephalopathy and eventually death by kernicterus. Despite extensive studies, the molecular and cellular mechanisms of bilirubin toxicity are still poorly defined. To fill this gap, we investigated the molecular processes underlying neuronal injury in a mouse model of severe neonatal jaundice, which develops hyperbilirubinemia as a consequence of a null mutation in the Ugt1 gene. These mutant mice show cerebellar abnormalities and hypoplasia, neuronal cell death and die shortly after birth because of bilirubin neurotoxicity. To identify protein changes associated with bilirubin-induced cell death, we performed proteomic analysis of cerebella from Ugt1 mutant and wild-type mice. Proteomic data pointed-out to oxidoreductase activities or antioxidant processes as important intracellular mechanisms altered during bilirubin-induced neurotoxicity. In particular, they revealed that down-representation of DJ-1, superoxide dismutase, peroxiredoxins 2 and 6 was associated with hyperbilirubinemia in the cerebellum of mutant mice. Interestingly, the reduction in protein levels seems to result from post-translational mechanisms because we did not detect significant quantitative differences in the corresponding mRNAs. We also observed an increase in neuro-specific enolase 2 both in the cerebellum and in the serum of mutant mice, supporting its potential use as a biomarker of bilirubin-induced neurological damage. In conclusion, our data show that different protective mechanisms fail to contrast oxidative burst in bilirubin-affected brain regions, ultimately leading to neurodegeneration. PMID:25950469

    We studied the landscape distribution of endemic Hawaiian hoary bats (Lasiurus cinereus semotus) on the north Ko‘olau Mountains of O‘ahu, Hawai‘i, from May 2013 to May 2014, while simultaneously studying their behavior at wind turbines within the broader landscape. This research aimed to assess the risk that wind turbines pose to bats on the island and integrated a variety of methods, including acoustic monitoring, thermal videography, and fatality searches.Our findings indicate that hoary bats were acoustically cryptic and occurred sparsely in the region. Overall site occupancy rate was 55% during the 1-year period of acoustic monitoring at 23 sites, and there was only an 8% chance of acoustically detecting a bat on a given night if it was present. We detected bats less frequently in windward northern parts of the study area and at windy, lower-elevation sites with rough terrain. Bats were detected more frequently in leeward southern parts of the study area and at wind-sheltered, higher-elevation sites with flat ridgetops. Acoustic detections were consistently low from October through February and increased at most sites to peak in April through August. However, meteorological conditions were not found to be associated with the acoustic prevalence of bats on a night-to-night basis. We observed more than three thousand events involving bats during six months of nightly video surveillance at four wind turbines. Video monitoring revealed several links to weather at the local scale, despite acoustic detections not clearly relating to weather in our broader landscape analysis. Video demonstrated bats occurring near turbines more often on nights with little rain, warmer temperatures, moderate wind speeds, low humidity, and the low but rising barometric pressures indicative of fair weather and improved foraging conditions. Video monitoring also demonstrated that the presence of bats near turbines strongly correlates with insect presence. We detected bats on video rather infrequently, averaging only one to two passes per hour. Most detections were brief (median = 4.0 sec) and involved single bats (97%), with the amount of time during which bats were observed totaling to only 0.10% of the video analyzed (about 3.8 hours of 3,847 total hours). Bats frequently foraged in the airspace near turbines. These results differ from a recent similar study on the mainland (continental North America) and may indicate that Hawaiian hoary bats spend less time closely approaching wind turbines and show less interest in them than their more-migratory mainland conspecifics. We speculate that the Hawaiian hoary bats we observed were locally resident and frequenting high-quality habitat  near familiar structures. In contrast, hoary bats observed at wind facilities on the mainland appear to approach and investigate unfamiliar landscape structures that they mistake for trees as they migrate long distances. Consequently, Hawaiian hoary bats may be less susceptible to fatality at wind turbines on a per-encounter basis than hoary bats in North America. Only one bat carcass was found at the four turbines searched daily for six months. The relatively high probability of finding carcasses provided strong assurance that few carcasses were likely missed—there was less than a 10% chance that total fatality at the four turbines monitored for half a year exceeded three bats.

    Full Text Available The article explores the dramas where the city is depicted as a special place determining the dramatization of a piece of work. The city symbolism is analyzed according to the criteria of the archetypal city images formulated by M. Eliade, and J. Lotman. The first part of the article ”A sacral city – Vilnius” deals with historical dramas (“Gediminas’ Dream” by A. Fromas Gužutis, “Kęstutis’ Death” by Maironis, “Radvila the Thunder”, “The Fate of Twilight ”, and “Barbora Radvilaite” by B. Sruoga, “Živilė” by A. Škėma, “Barbora Radvilaitė” by J. Grušas, “The Cathedral” by J. Marcinkevičius, “The Crown and the Sand” by R. Samulevičius, and etc.. In Lithuanian dramaturgy, Vilnius meets all the criteria of an ideal, sacred city. In poetic dramas, Vilnius is described as a superb creation embodying the plenitude of human existence. The second part of the article “The Demonic City” deals with the dramas in which the city symbolism conveys the opposite of a sacred, ideal city – an eccentric and demonic city localized in the “outskirts” of cultural space. This aspect of the city symbolism is analyzed in separate subsections: “The Doomed City” (“The Sea Bells” by Vydūnas, and “The Shackles” by M. Pečkauskaitė, “The Profane City” (the comedy “Vain Attempts” by P. Vaičiūnas, “Julijana” by A. Škėma, “A Spring Song” by B. Sruoga, “The Mammoth Hunt” by K.

    Full Text Available The last 25 years have been in many Polish cities a period of intensive modernization and renewals of the existing public spaces. Most of all the resurfacing of the pavement and changing of street furniture have been held. In many cases, the transformations in the urban areas were integrated with exclusion from traffic. The question arises what criteria architects or landscape architects follow and what design solutions apply. It is also interesting how the new shape of the floor in public spaces (understood here as a pavement and street furniture together can help to create integrating and activating space for residents. And how it can affect the quality of life in a wider area. This article attempts to answer these questions based on new solutions on Kosciuszko Square in Białystok, executed in 2005-2009.

    Electron paramagnetic resonance (EPR) studies have been investigated at X-band microwave frequency on Cu2+ ion incorporated into the single crystal of potassium succinate-succinic acid (KSSA) at room temperature. The angular variation of the EPR spectra has shown two magnetically in-equivalent Cu2+ sites in the KSSA single crystal system. The spin Hamiltonian parameters g and A are determined which reveals that the site I and site II occupied in rhombic and axial local field symmetry around the impurity ion. Among the two paramagnetic impurity ions, sites one occupies at substituitional position in the place of monovalent cation (K+) in the crystal whereas the other enters in its lattice interstitially by the correlation of EPR and crystal structure data. From the calculated principle values gxx, gyy, gzz and Axx, Ayy, Azz of both the sites, the admixture coefficients and molecular orbital coefficients were evaluated which gives the information of ground state wave function and types of bonding of impurity ions with the ligands.

    In Germany, about 20% of the total population have a migration background. Differences exist between migrants and non-migrants in terms of health care access and utilisation. Colorectal cancer is the second most common malignant tumour in Germany, and incidence, staging and survival chances depend, amongst other things, on ethnicity and lifestyle. The current study investigates whether stage at diagnosis differs between migrants and non-migrants with colorectal cancer in an area of high migration and attempts to identify factors that can explain any differences. Data on tumour and migration status will be collected for 1,200 consecutive patients that have received a new, histologically verified diagnosis of colorectal cancer in a high migration area in Germany in the previous three months. The recruitment process is expected to take 16 months and will include gastroenterological private practices and certified centres for intestinal diseases. Descriptive and analytical analysis will be performed: the distribution of variables for migrants versus non-migrants and participants versus non-participants will be analysed using appropriate χ2-, t-, F- or Wilcoxon tests. Multivariable, logistic regression models will be performed, with the dependent variable being the dichotomized stage of the tumour (UICC stage I versus more advanced than UICC stage I). Odds ratios and associated 95%-confidence intervals will be calculated. Furthermore, ordered logistic regression models will be estimated, with the exact stage of the tumour at diagnosis as the dependent variable. Predictors used in the ordered logistic regression will be patient characteristics that are specific to migrants as well as patient characteristics that are not. Interaction models will be estimated in order to investigate whether the effects of patient characteristics on stage of tumour at the time of the initial diagnosis is different in migrants, compared to non-migrants. An association of migration status or other socioeconomic variables with stage at diagnosis of colorectal cancer would be an important finding with respect to equal health care access among migrants. It would point to access barriers or different symptom appraisal and, in the long term, could contribute to the development of new health care concepts for migrants.

    Burning rate and specific impulse of a solid propellant are extremely important parameters in a design of a solid rocket motor. In this study, the relations between the burning rate and the amount of energy contained in HMX-CMDB propellants wherein the amount of energy is varied by adding HMX (High Melting Point Explosive). The following results are obtained. The final flame temperature is getting higher when the amount of energy is increased by adding HMX into a double-base propellant. The higher the final flame temperature is, the lower the burning rate is. Dark zone temperature, as a physical property, is lowered when the containing amount of energy is increased by adding HMX into the double-base propellant. This is because that, when weight fraction of HMX is increased, reaction heat at burning surface decreases, and the reaction in fizz zone is getting slower. The higher the dark zone temperature is, the higher the burning rate is. 20 refs., 11 figs., 1 tab.

    Full Text Available A production of „HSW“ in block of flats areas by solar collectors means a real alternative to the traditional way of heating by fossil fuels (coal, gas. With this method, it’s possible to save ca. 50 % of energy from the net of the central service of the heat, what can reduce the production of pollutants in the locality, or it can enable to increase the quantity of customers without claims for the restructuralization of the central source. Because Slovakia is the producer of quality solar collectors it’s suitable to use them just for this reason, which could be projected into the price reduction of relatively expensive present systems. On the other side, when using the flat roofs on the block of flats, other useful places are hot occupied and the heating source is nearby the place of it sconsumption. In this case, a collaboration of the solar system and the Central Service of Heat is especially suitable in time with a shortage of the solar radiation.

    The laser heat treatment of SUS304 steel was studied to lower the intergranular corrosion sensitivity of austenitic stainless steel. By the short-time heating around 923K, the SUS304 steel is sensitized to the intergranular corrosion with the deposition of Cr carbide into the granular field of crystals. To recover it, it is necessary to solidly dissolve, and simultaneously, quickly cool the Cr carbide above 1273K. For such solution heat treatment, CO2 laser beams were used with the treatment condition that the power and beam diameter were 800 to 1200W and 0.3 to 0.64cm, respectively. Regardless of both power density and beam diameter, the desensitization was observed at heating temperatures above 1323K. As a result of calculation by simulation, the solid dissolution of Cr carbide and recovery of Cr`s depletion zone in the granular field of crystals took place in a very short time at heating temperatures above 1323K.

    Since the early stage of the development of the prestressed concrete (PC) manufacturing techniques, it has been said that forming a single PC structure by uniting precast segments with PC steel material into one is a construction method making the most of the feature of PC. This paper roughly describes the history of the development of PC and concrete examples of PC, centering on the construction techniques effectively utilizing the principle of PC and its materials. Especially, a PC bridge is superior to a steel bridge with respect to noise and vibration, so that the construction works of replacing railway steel bridges and railway elevated bridges by PC bridges have come to be seen in many places recently. In order to increase the span of a PC bridge, the reduction of the weight is a major factor. Therefore, an outer cable system has come to be used so as to reduce the thickness is cross section of the web of a PC beam as much as possible. The changes of the maximum span of cable stayed bridge are listed in a table in comparison of PC bridges with steel bridges. 29 refs., 9 figs., 1 tab.

    By establishing microtechnology using molecular-level bottoming-up (molecular harmonization) by imitating the system of living organism, the paper described the R and D of molecular harmonized materials aiming at developing high-functional/high-performance materials such as high-performance catalyst, photo-information functional materials and sensing materials. Under consignment from NEDO, Japan Chemical innovation Institute started the 5-year plan in fiscal 1997. Self-assembled molecular films, in which organic molecules are orderly arranged by self-assembly, aim at developing new memory/optical/sensing materials. Mesophase materials which are such materials as liquid crystal showing the intermediate state between solid and liquid, develop optical/photoconductive materials using precise molecular orientation controllability. Macroporous materials are such substances as zeolite having molecular size micro pores. The paper aims at establishment of synthesis techniques of them and development of high-performance catalyst, etc. using them. In the comprehensive investigational research, conducted was a survey of the trend overseas in addition to a study of subjects in question. Further, the supporting basic study was reconsigned to universities, etc. 57 refs., 62 figs., 17 tabs.

    The paper described multi-stimuli-responsive materials out of the technology developments for creating original high-functional materials under the system of R and D of industrial scientific technologies. These are materials which repeatedly reproduce functions such as separation, penetration and movement in response to stimuli by imitating living organisms. In relation to polymer multi-stimuli-responsive materials, various copolymers were synthesized using N-acetyl (meta) acrylamide, of which the synthesis method was established in the previous fiscal year, as a main component, and thermal responsive polymer with upper critical solution temperature which becomes a base of separation functional materials was searched for. By immobilizing it with molecular recognition ligand, measured was thermal dependence of affinity of the immobilized matter to albumin. Also studied were molecular recognition cell adhesion/separation functional materials. Concerning composite multi-stimuli-responsive materials, with the use of silica microcapsule surface-immobilized with silane coupling agent, studied were the optimum conditions for immobilizing thermo-responsive polymer to the surface of the capsule. Using motion functional materials by ion exchange resin, obtained was motion functionality which is satisfactory at the state of practical use. 94 refs., 82 figs., 16 tabs.

    With the purpose of establishing innovative manufacturing technology for microstructure steel having a crystal grain size of about 1 {mu}m or less and a dimensional thickness of 1 mm or more by homogeneous multi-phase structure steel making, R and D was conducted, with fiscal 2000 results compiled. This year, R and D, using a multi-functional integrated test rolling mill, resulted in obtaining ultra-fine grained steel, a steel plate of 5 mm in thickness and 100 mm in width with grains of 1 {mu}m or less homogeneously in the thickness direction. In the investigation on the characterization by the steel plate sample thus obtained and on the method for preventing degradation in elongation, it was proved that an ultra-refined microstructure containing martensite or austenite as the secondary phase has a suppressing effect on the degradation in elongation. Further, examination was made on the widening of a process window for the practicability in the future and on the optimization of large strain deformation conditions. In the method of analyzing and evaluating ultra-refined microstructures, an analysis technology such as an in-lens SEM was proved to be extremely effective on the analysis of microstructures of supermetals created by large strain deformation as well as on the observation of microstructures of a submicron level.

    A 1 T/D solvent-extraction type coal liquefaction test plant was constructed and operated to obtain the technical data for the design of, and establish the techniques for, an efficient coal liquefaction plant. The FY 1980 program includes surveys on the materials for coal liquefaction plants, covering those already developed and under development, to clarify the problematical points; drafting the test schedules; and conceptual designs of the material testing facilities. The major problems involved in the materials for coal liquefaction plants include erosion by fluidizing coal slurry, hydrogen embrittlement of the reactor materials, and corrosion by the liquefaction products (e.g., stress-corrosion cracking of austenitic steel, and corrosion by organic acids). The surveys on materials research trends suggest that USA seems to concentrate their research efforts on the reactor materials. The corrosion tests are mostly of in-plant tests, but the stress corrosion and slurry erosion tests are conducted on a laboratory scale. The conceptual designs are drawn for some testing units, e.g., the loop type material testing unit and basic testing unit for jet-spray type slurry erosion. (NEDO)
