    Ficus deltoidea (moraceae) is a herbal plant with medicinal values. Previous studies reported that the F. deltoidea contains a high level of bioactive compounds such as flavonoids. A cDNA encodes for chalcone isomerase was identified from F. deltoidea, designated as FdCHI, which involved in the isomerization of naringenin chalcone to naringenin. Naringenin is a key branch point for the synthesis of rutin, which is believed involved in defense mechanism in the plant. Therefore, we hypothesized that there might be a direct relationship between FdCHI expression level and rutin production in leaves of F. deltoidea var. deltoidea (FDD) and F. deltoidea var. angustifolia (FDA). Our result showed that expression level of FdCHI in leaves FDD was greater than FDA. Analysis of High Performance Liquid Chromatography (HPLC) revealed that rutin was only detected in FDA leaves. Based on the results between FdCHI expression and rutin production, this study concluded that there is no relationship between FdCHI expression and rutin production in leaves of FDA and FDD.

    Ficus deltoidea or locally known as Mas cotek is one of the common medicinal plants used in Malaysia. Our previous studies showed that this plant have blood glucose lowering effect. Glucose uptake into muscle and adipocytes cells is one of the known mechanisms of blood glucose lowering effect. This study was performed to evaluate the effect of Ficus deltoidea on glucose uptake activity into muscle cells. The cells were incubated with Ficus deltoidea extracts either alone or combination with insulin. Amount of glucose uptake by L6 myotubes was determined using glucose tracer, 2-deoxy-(1- 3 H 1 )-glucose. The results showed that Ficus deltoidea extracts at particular doses enhanced basal or insulin-mediated glucose uptake into muscle cells significantly. Hot aqueous extract enhanced glucose uptake at the low concentration (10 μg/ ml) whereas methanolic extract enhanced glucose uptake at low and high concentrations. Methanolic extract also mimicked insulin activity during enhancing glucose uptake into L^ muscle cells. Glucose uptake activity of Ficus deltoidea could be attributed by the phenolic compound presence in the plant. This study had shown that Ficus deltoidea has the ability to enhance glucose uptake into muscle cells which is partly contributed the antidiabetic activity of this plant. (author)

    Full Text Available Ficus deltoidea from the Moraceae family has been scientifically proven to reduce hyperglycemia at different prandial states. In this study, we evaluate the mechanisms that underlie antihyperglycemic action of Ficus deltoidea. The results had shown that hot aqueous extract of Ficus deltoidea stimulated insulin secretion significantly with the highest magnitude of stimulation was 7.31-fold (P<0.001. The insulin secretory actions of the hot aqueous extract involved K+ ATP channel-dependent and K+ ATP-channel-independent pathway. The extract also has the ability to induce the usage of intracellular Ca2+ to trigger insulin release. The ethanolic and methanolic extracts enhanced basal and insulin-mediated glucose uptake into adipocytes cells. The extracts possess either insulin-mimetic or insulin-sensitizing property or combination of both properties during enhancing glucose uptake into such cells. Meanwhile, the hot aqueous and methanolic extracts augmented basal and insulin-stimulated adiponectin secretion from adipocytes cells. From this study, it is suggested that Ficus deltoidea has the potential to be developed as future oral antidiabetic agent.

    This study examined the anti-adipogenic effects of extracts of Ficus deltoidea var. deltoidia and var. angustifolia, a natural slimming aid, on 3T3-L1 adipocytes. Methanol and water extracts of leaves of the F. deltoidea varieties were analyzed to determine their total flavonoid content (TFC) and total phenolic content (TPC), respectively. The study was initiated by determining the maximum non-toxic dose (MNTD) of the methanol and water extracts for 3T3-L1 preadipocytes. Possible anti-adipogenic effects were then examined by treating 2-d post confluent 3T3-L1 preadipocytes with either methanol extract or water extract at MNTD and half MNTD (½MNTD), after which the preadipocytces were induced to form mature adipocytes. Visualisation and quantification of lipid content in mature adipocytes were carried out through oil red O staining and measurement of optical density (OD) at 520 nm, respectively. The TFCs of the methanol extracts were 1.36 and 1.97 g quercetin equivalents (QE)/100 g dry weight (DW), while the TPCs of the water extracts were 5.61 and 2.73 g gallic acid equivalents (GAE)/100 g DW for var. deltoidea and var. angustilofia, respectively. The MNTDs determined for methanol and water extracts were (300.0 ± 28.3) and (225.0 ± 21.2) µg/ml, respectively, for var. deltoidea, while much lower MNTDs [(60.0 ± 2.0) µg/ml for methanol extracts and (8.0 ± 1.0) µg/ml for water extracts] were recorded for var. angustifolia. Studies revealed that the methanol extracts of both varieties and the water extracts of var. angustifolia at either MNTD or ½MNTD significantly inhibited the maturation of preadipocytes. The inhibition of the formation of mature adipocytes indicated that leaf extracts of F. deltoidea could have potential anti-obesity effects.

    Plant authentication is a quality assurance process that ensures the correct plant species and plant parts are used as raw materials for herbal medicines. Identification methods employed in the authentication of herbal materials are macroscopic identification and microscopic examination. Macroscopic examination involves the comparison of morphological characters that are visible with the naked eye or under low magnification with descriptions of the plant or botanical drug in floras or monographs. Characters such as size, shape and colour of leaves (or leaf fragments), flowers or fruits are commonly used in macroscopic identification. Microscopic examination focuses on anatomical structures in the plant material that are visible only with the help of a microscope. Features such as trichome (hair) shape and structure, the arrangement of stomata in the epidermis, the presence or absence of compounds such as mucilage, starch or lignin, or the presence of tissues with characteristic cells might be used in the microscopic identifications of herbal drugs. Ficus deltoidea Jack (Moraceae) has been classified into various varieties such as var. deltoidea, var. angustifolia, var.bilobata, var. intermedia, var.kunstleri, var. motleyana, and var. trengganuensis. Morphological variations and unclear boundaries between varieties can lead to the misleading identification. Thus, correct identification of F. deltoidea varieties is important. The present study aims to examine the macroscopic morphology and microscopic anatomy of F. deltoidea var. kunstleri leaf, as the main phyto-ingredient in DELTOZIDE phyto pharmaceutical product.

    Tabat barito (Ficus deltoidea Jack) is a name given by Dayak Tribe who lived in Borneo-Kalimantan and it is belongs to the moraceae. Almost all of the parts of F. deltoidea plant is widely used as a medicinal property. The total flavonoid content (TFC) and antioxidant activity from cultivated and wild F. deltoidea leaves and stems extract were assessed. Total flavonoid content was estimated by using Aluminium chloride colorimetric method and expressed as catechin equivalents (mg CE g-1 extract) and the antioxidant activity by the DPPH (2,2-diphenyl-1-picryl hydrazyl) method. The content of total flavonoid of leaves and stems (430.77 and 371.80 µg CE mg-1 extract) of cultivated F. deltoidea were higher than in the wild leaves and stems (114.82 and 66.67 µg CE mg-1 extract). The IC50 of leaves extract of cultivated and wild F. deltoidea, based on the DPPH assay, has a strong antioxidant activity (34.19 and 39.31 µg mL-1 extract) as compared to stems extract. These results showed that the cultivated F. deltoidea are suitable source for medicinal properties and the leaves could be exploited as source of natural antioxidants.

    Full Text Available In this study, the effect of extraction parameters (ethanol concentration, sonication time, and solvent-to-sample ratio on Ficus deltoidea leaves was investigated using ultrasound-assisted extraction by response surface methodology (RSM. Total phenolic content (TPC of F. deltoidea extracts was identified using Folin-Ciocalteu method and expressed in gallic acid equivalent (GAE per g. Box-Behnken statistical design (BBD was the tool used to find the optimal conditions for maximum TPC. Besides, the extraction yield was measured and stated in percentage. The optimized TPC attained was 455.78 mg GAE/g at 64% ethanol concentration, 10 minutes sonication time, and 20 mL/g solvent-to-sample ratio whereas the greatest extraction yield was 33% with ethanol concentration of 70%, sonication time of 40 minutes, and solvent-to-material ratio at 40 mL/g. The determination coefficient, R2, for TPC indicates that 99.5% capriciousness in the response could be clarified by the ANOVA model and the value of 0.9681 of predicted R2 is in equitable agreement with the 0.9890 of adjusted R2. The present study shows that ethanol water as solvent, a short time of 10 minutes, and adequate solvent-to-sample ratio (20 mL/g are the best conditions for extraction.

    Changes in the content of the furostanol glycosides protodioscin and deltoside, particularly that of the (25S)-isomers of the glycosides, during suspension cultivation of different lines of Nepal yam (Dioscorea deltoidea Wall.) cells of the strain IFR-DM-0.5 has been investigated. The composition of furostanol glycosides has been characterized, and the dynamics of the accumulation of individual glycosides during lengthy subcultivation of cells maintained in flasks or in a barbotage bioreactor has been analyzed. A positive correlation between the growth and accumulation of substances that belonged to the class of furostanol glycosides has been demonstrated for cultured dioscorea cells, whereas the content of some of the individual glycosides varied considerably between the lines of the strain, cultures maintained under different conditions, and even between cells in different phases of the growth cycle. The increased content of (25R)-forms of the glycosides (protodioscin and deltoside) was correlated with a decrease in the cellular growth rate, whereas an increase in culture growth intensity occurred concomitantly to an increase of the amount of (25S)-isomers. This may be indicative of the specific stimulatory effect of (25S)-glycosides, but not the (25R)-forms, on cell proliferation in vitro. Thus, the concentration of (25S)-forms may increase due to the autoselection of cells capable of intensive division during prolonged cultivation.

    Full Text Available Genetic structure and biodiversity of the medicinal plant Ficus deltoidea have rarely been scrutinized. To fill these lacunae, five varieties, consisting of 30 F. deltoidea accessions were collected across the country and studied on the basis of molecular and morphological data. Molecular analysis of the accessions was performed using nine Inter Simple Sequence Repeat (ISSR markers, seven of which were detected as polymorphic markers. ISSR-based clustering generated four clusters supporting the geographical distribution of the accessions to some extent. The Jaccard’s similarity coefficient implied the existence of low diversity (0.50–0.75 in the studied population. STRUCTURE analysis showed a low differentiation among the sampling sites, while a moderate varietal differentiation was unveiled with two main populations of F. deltoidea. Our observations confirmed the occurrence of gene flow among the accessions; however, the highest degree of this genetic interference was related to the three accessions of FDDJ10, FDTT16 and FDKT25. These three accessions may be the genetic intervarietal fusion points of the plant’s population. Principal Components Analysis (PCA relying on quantitative morphological characteristics resulted in two principal components with Eigenvalue >1 which made up 89.96% of the total variation. The cluster analysis performed by the eight quantitative characteristics led to grouping the accessions into four clusters with a Euclidean distance ranged between 0.06 and 1.10. Similarly, a four-cluster dendrogram was generated using qualitative traits. The qualitative characteristics were found to be more discriminating in the cluster and PCA analyses, while ISSRs were more informative on the evolution and genetic structure of the population.

    Andrographis paniculata , Gynura procumbens , Ficus deltoidea and Curcuma xanthorrhiza are commonly consumed as herbal medicines. However their effects on human liver glucuronidation activity are not yet evaluated. In this study, we evaluate the inhibitory Effects of Andrographis paniculata, Gynura procumbens, Ficus deltoidea and Curcuma xanthorrhiza extracts and their constituents on human liver glucuronidation activity. Herbal extracts (aqueous, methanolic and ethanolic extracts) and their constituents were incubated with human liver microsomes with the addition of UDPGA to initiate the reaction. Working concentrations of herbal extracts and their constituents ranged from 10 μg/mL to 1000 μg/mL and 10 μM to 300 μM respectively. IC50 was determined by monitoring the decrement of glucuronidation activity with the increment of herbal extracts or phytochemical constituent's concentrations. All herbal extracts inhibited human liver glucuronidation activity in range of 34.69 μg/mL to 398.10 μg/mL whereas for the constituents, only xanthorrhizol and curcumin (constituents of Curcuma xanthorrhiza ) inhibited human liver glucuronidation activity with IC50 of 538.50 and 32.26 μM respectively. In the present study, we have proved the capabilities of Andrographis paniculata , Gynura procumbens , Ficus deltoidea and Curcuma xanthorrhiza to interfere with in vitro glucuronidation process in human liver microsomes. This study documented the capabilities of Andrographis paniculata , Gynura procumbens , Ficus deltoidea and Curcuma xanthorrhiza to inhibit human liver glucuronidation activity which may affect the metabolism of therapeutic drugs or hazardous toxicants that follow the same glucuronidation pathway.

    Full Text Available The wood of the palm Iriartea deltoidea is an excellent material used for building, furniture and handicrafts in the Colombian Amazon, especially in the Amazon foothills where a small industry has developed around this species. We report the management practices, uses and commercial trends of this species in the municipality of Mocoa (Putumayo. We present data on population structure at three contrasting sites. The estimated demand of stems is ca. 750 per year, and the area necessary to supply them is 17-83 ha. Harvesting is carried out in natural forests or in pastures. The management practices are selective logging, sowing of seedlings and sparing of palms in pastures. Taking into account the natural condition of Mocoa, the abundance of the species, its growth rate and the current extraction system, productivity could grow if the followings activities were performed: enrichment of secondary forests, re-population of eroded areas, reduction of deforestation, and establishment of minimal harvest sizes based on height rather than diameter.

    To verify noise emissions from the usual activities in an operating geothermal field, noise measurements were carried out in a 4.2 km{sup 2} area in the southern zone of the Los Azufres, Mich., geothermal field. There are seven production wells operating here and three abandoned wells. The average noise emission in the southern zone was 36.5 decibels (dB), regarded as the natural reading of environmental-noise emission. In the Christmas (valves) tree for operating production wells, the noise ranges from 70.9 to 91.7 dB, while in open discharging valves for steam-pipes, the noise can reach 118 dB. In Mexico the maximum permissible limit of noise on the periphery of a property is 68 dB in daytime and 65 dB at night. Based on measurements made at the periphery of lots where the geothermal wells are located, four out of seven production wells measured do not exceed the maximum allowable level, while the other three seem to exceed it. However no definite limits exist for the lots. It is recommended that the measurement points as indicated by the official standard in environmental matters be re-established, which will enable noise emissions by several wells that have exceeded the permissible limit, to actually fall within it.

    Full Text Available O objetivo deste trabalho foi investigar alterações fisiológicas e bioquímicas em sementes osmocondicionadas de tamboril-da-mata (Platymiscium pubescens Micheli. Foram analisados o crescimento do eixo embrionário, a germinação, as alterações na parede celular, a mobilização de carboidratos e proteínas e a atividade de a-galactosidase. Observou-se que o teor de umidade das sementes da testemunha aumentou continuamente até 96 horas de embebição, enquanto as mantidas nas soluções de PEG estabilizaram-se a partir de 48 horas. A germinação ocorreu somente nas sementes mantidas em água, alcançando 30% em 120 horas. As sementes mantidas em solução-0,4 MPa de PEG por 120 horas tiveram 66% de germinação quando transferidas para água, sendo a maior em relação aos demais potenciais. A massa fresca e o comprimento do embrião aumentaram significativamente durante o período de 120 horas em solução de PEG (-0,4 MPa/120 horas, porém a massa seca teve incremento não-significativo. Os teores de arabinose e xilose em membranas lavadas com água decresceram significativamente durante o osmocondicionamento. A galactose não foi detectada na membrana em 120 horas. A arabinose mostrou ser a principal constituinte da membrana. A atividade de a-galactosidase mostrou diferença significativa durante o período de 120 horas.

    The fungal genus Suillus Micheli ex S. F. Gray plays important roles in the survival and growth of plant seedlings. Humans have utilized these ectomycorrhizal fungi to enhance the nutrient uptake and defense systems of plants, particularly in the reforestation of coniferous forests. The genus Suillus is easily distinguishable by its distinctive morphological features, although the morphology of the fruiting body does not facilitate reliable interspecies discrimination. On the basis of micro-morphological features and internal transcribed spacer sequence analysis, we found that 51 of 117 Korean Suillus specimens had initially been misidentified. The list of the 12 Suillus species previously recorded in Korea was re-evaluated and revised to only eight distinct species: S. americanus, S. bovinus, S. granulatus, S. grevillei, S. luteus, S. pictus, S. placidus, and S. viscidus. We provide taxonomical descriptions for six of these species from the sample specimens.

    Echinodorus macrophyllus Mich. (Chapeu-de-couro) is popularly used as diuretic, anti-arrhythmic, anti-inflammatory, and anti-rheumatic agents. Leaves of this species are largely commercialized and show high level of microbiological contamination (bacteria and fungi). This work describes the effect of the 60 Co γ-radiation on the phenol fractions obtained from the leaves of E. macrophyllus. trans-Ferulic acid, (E)-caffeoyltartronic acid, 6-C-(1-hexitol)-apigenin, and 6-C-(1-hexitol)-luteolin were isolated by preparative HPLC. HPLC chromatograms showed concentration changes of some phenolic constituents, suggesting the formation of radiolytic products. The phenol fractions were active against Bacillus subitilis and Staphylococcus aureus and showed high antioxidant activity. However, the antibacterial and antioxidant activities reduced when the absorbed dose was increased. - Highlights: → Effects of the γ-radiation on the chemical constituents of the leaves of E. macrophyllus. → To determine the conditions, which are sufficient for microbiological decontamination. → Analysis by HPLC of the phenol fractions obtained from the leaves of E. macrophyllys. → Effects of the γ-radiation in the antioxidant and antimicrobial activities of E. macrophyllus.

    The Chapeu-de-couro (Echinodorus macrophyllus (Kunth) Micheli) is a native plant from Brazil, which has been mainly used in medicinal application being a potent antirheumatic and diuretic, in the production of soft drinks, and also in the ornamentation of aquariums. In this paper, the metals and metalloids for the leaves of chapeu-de-couro collected in the Paraguacu River from the city Cachoeira, Bahia State, Brazil, was determined and evaluated using multivariate analysis. The samples were digested using nitric acid and hydrogen peroxide and were analyzed using inductively coupled plasma mass spectrometry. The accuracy of the method was confirmed by analysis of a certified reference material of apple leaves, furnished by National Institute of Standard and Technology. The study involved 15 samples of the Paraguacu River. The results expressed as milligrams of element per kilogram of sample demonstrated that the concentration ranges varied: 1.39-5.27 for chromium, 44.85-165.39 for manganese, 0.55-0.84 for arsenic, 0.01-3.94 for antimony, and 0.18-0.31 for lead. The principal component analysis and hierarchical cluster analysis evidenced that the concentrations of the metals and metalloids varied according with the variations in the water of the Paraguacu.

    This study aims to evaluate the in vitro cytotoxic and anti-migratory effects of Ficus deltoidea L. on prostate cancer cells, identify the active compound/s and characterize their mechanism of actions. Two farmed varieties were studied, var. angustifolia (FD1) and var. deltoidea (FD2). Their crude methanolic extracts were partitioned into n-hexane (FD1h, FD2h) chloroform (FD1c, FD2c) and aqueous extracts (FD1a, FD2a). Antiproliferative fractions (IC50 < 30 μg/mL, SRB staining of PC3 cells) were further fractionated. Active compound/s were dereplicated using spectroscopic methods. In vitro mechanistic studies on PC3 and/or LNCaP cells included: annexin V-FITC staining, MMP depolarization measurements, activity of caspases 3 and 7, nuclear DNA fragmentation and cell cycle analysis, modulation of Bax, Bcl-2, Smac/Diablo, and Alox-5 mRNA gene expression by RT-PCR. Effects of cytotoxic fractions on 2D migration and 3D invasion were tested by exclusion assays and modified Boyden chamber, respectively. Their mechanisms of action on these tests were further studied by measuring the expression VEGF-A, CXCR4, and CXCL12 in PC3 cells by RT-PCR. FD1c and FD2c extracts induced cell death (P < 0.05) via apoptosis as evidenced by nuclear DNA fragmentation. This was accompanied by an increase in MMP depolarization (P < 0.05), activation of caspases 3 and 7 (P < 0.05) in both PC3 and LNCaP cell lines. All active plant extracts up-regulated Bax and Smac/DIABLO, down-regulated Bcl-2 (P < 0.05). Both FD1c and FD2c were not cytotoxic against normal human fibroblast cells (HDFa) at the tested concentrations. Both plant extracts inhibited both migration and invasion of PC3 cells (P < 0.05). These effects were accompanied by down-regulation of both VEGF-A and CXCL-12 gene expressions (P < 0.001). LC–MS dereplication using taxonomy filters and molecular networking databases identified isovitexin in FD1c; and oleanolic acid, moretenol, betulin, lupenone, and lupeol in FD2c. In conclusion

    Background: Ficus deltoidea (FD) is one of the native plants widely distributed in several countries in Southeast Asia. Previous studies have shown that FD leaf possess antinociceptive, wound healing and antioxidant properties. These beneficial effects have been attributed to the presence of primary and secondary metabolites such as polyphenols, amino acids and flavonoids. Objective: The aim was to develop a reverse phase high-performance liquid chromatography method with ultraviolet detection that involves precolumn derivatisation with O-phthaladehyde for simultaneous analysis of two amino acids L-citrulline and L-arginine in FD leaf extracts. Materials and Methods: An isocratic elution program consisting of methanol: acetonitrile: Water at 45:45:10 v/v (solvent A) and 0.1 M phosphate buffer pH 7.5 (solvent B) at A: B v/v ratio of 80:20 on Zorbax Eclipse C18 SB-Aq column (250 × 4.6 mm, 5 μm) were used. The flow rate was set at 1 ml/min and detection was carried out at 338 nm with 30 min separation time. Results: Good linearity for L-citrulline and L-arginine was obtained in the range 0.1-1000 μg/ml at R2 ≥ 0.998. The limit of detection and limit of quantification values for both L-citrulline and L-arginine were 1 and 5 μg/ml, respectively. The average of recoveries was in the range 94.94-101.95%, with relative standard deviation (%RSD) less than 3%. Intra- and inter-day precision was in the range 96.36-102.43% with RSD less than 2%. Conclusion: All validation parameters of the developed method indicate the method is reliable and efficient for simultaneous determination of L-citrulline and L-arginine for routine analysis of FD.

    Unit 12 of the Los Azufres, Mich., geothermal field is a binary cycle unit of 1.45 MW, installed at the pad of production well Az-22. There are two separators on this pad. One separates the mix extracted from well Az-22 and the other from adjacent wells. The separated brine from both separators is gathered in a horizontal tank and sent to Unit 12. The steam is sent to Unit 7, which generates 50 MW. Once some interference occurred affecting the power generation of Unit 7 when Unit 12 was off line. This was caused by the original flow arrangement and water-level control system. To avoid interference, a water-level control system was designed and installed in the separators. The system operates independently of Unit 12, with tanks in each separator connected by a pipe. Regulation of the water level is accomplished by three motor valves and a level sensor. To ensure permanent feeding of electrical power to the valves, an automatic system was installed from transmission lines of 23 and 115 kV. In case both lines fail, there is an uninterrupted power supply (UPS) unit. At the beginning of 2005, Unit 12 was again online with a modified water-level control system that has operated satisfactorily since then. Its short periods offline have not affected Unit 7.

El agua separada de ambos se concentra en un tanque horizontal y de este pasa a la Unidad 12, mientras que el vapor se envia a la Unidad 7, de 50 MW. Por el tipo de arreglo original de flujo y control de nivel de agua en los equipos, ocurrian interferencias que provocaban que cuando la Unidad 12 se disparaba se afectara la generacion en la Unidad 7. Para evitar esta interferencia se diseno e instalo un sistema de control de

    The Mexican Federal Commission for Electricity injects brines produced by nearby geothermal wells into well Az-08, located in the Tejamaniles area, in the southwestern portion of Los Azufres, Mich., geothermal field. The main goals of this study are to determine whether or not the injected fluid recharges nine producing wells in the area, and if so, to estimate the fraction of the injected fluid recharging each producing well. Five of the selected wells produce mixes of liquid and steam and the rest produce only steam. For this reason, we designed this study with simultaneous injections of liquid- and steam-tracers. The nine selected producing wells detected the steam-tracer, and the five wells producing mixes detected the liquid-phase tracer. The residence curves of both tracers present a series of peaks reflecting the known fractured nature of the reservoir. The results show the feeding areas of the nine selected wells are recharged by the fluid injected into well Az-08. When this paper was written, the arrival of steam-tracers in all wells was completed, but the wells producing mixes of liquid and steam continued to record the arrival of the liquid-tracer. Until 407 days after injecting the tracer, the total percentage recovery of liquid phase tracer in the five wells producing mixes of liquid and steam was 3.5032%. The arrival of the steam tracer ended in all nine wells 205 days after the tracer was injected, with an overall recovery rate of 2.1553 x 10-2%. The recovery rates imply the recharge rates of the monitored wells by the injector Az-08 are modest, but it appears the amounts of the recovered liquid-phase tracer will increase significantly. The modest recovery rates suggest most of the fluid injected into the well Az-08 disperses in the reservoir, contributing to recharge and maintaining the pressure. Results reveal that: (i) the injected fluid is heated at depths from 700 to over 1000 m, where it boils and rises to reach the feeding areas of the

    Commercial exploitation in the Los Azufres geothermal field, Michoacan, Mexico, started in 1982 when the first five backpressure-power units of 5-MW each were commissioned. Nowadays the installed capacity is 188 MW from 14 units: five in the South Zone fed by steam produced from 18 production wells plus two binary-cycle power units fed by residual brines; and seven in the North Zone with steam supplied by 22 production wells. There are seven backpressure-power units with high specific consumption [between 14.5 and 13.6 tons per hour of steam (t/h) per MW]. Three operate in the South Zone and four in the North Zone. This paper shows a way to achieve more efficient use of the geothermal resource by replacing the seven backpressure units, which have completed their useful lifetime-or are close to do it-with two, new condensing power units with lower specific consumption: one unit of 50 MW to be located in the North Zone and the other of 25 MW to be placed in the South Zone. No new wells need be drilled. In this way, the average specific consumption would be reduced to 8.8-7.2 t/h per MW (saving 47% of the steam), the income for electric generation would be increased and the steam-extraction rate would remain the same.

    We ran two simultaneous tracer tests in the Maritaro-La Cumbre area of the Los Azufres geothermal field in Mexico. We wished to determine whether or not fluids injected in well Az-15 recharged the productive areas of six production wells and to estimate the fractions of injected fluid recovered in them, if any. Because only three of the wells produce water and all of them produce steam, two tracers were used, sulfur hexafluoride (SF{sub 6}) for the gas phase and 1,3,6 naphthalene trisulfonate (1,3,6-nts) for the liquid phase. All of the observation wells recorded SF{sub 6}, and the three water-producing wells recorded 1,3,6-nts, proving that fluids injected in well Az-15 do recharge the area of interest. When sampling was suspended, the three water-producing wells were still producing 1,3,6-nts at significant rates. The total recovery of 1,3,6-nts at wells Az-65D, Az-04 and Az-28, 279 days after injection when sampling was halted, were, respectively, 6.1%, 0.90% y 0.16%, for a total of 7.61%. We concluded that these quantities constitute the lower boundaries for the respective recovery factors. When sampling was halted, wells Az-65D, Az-66D and Az-30 were still producing some SF{sub 6} at lower rates, and the rest of the wells were no longer recording the gas phase tracer. The total recovery of SF{sub 6} at wells Az-65D, Az-04, Az-41, Az-30, Az-28 and Az-66D were, respectively, 4.82 e-02%, 1.37 e-03%, 1.48 e-03%, 6.38 e-04%, 1.38 e-03% y 4.31 e-04%, for a total of 5.35 e-02%.

    After the introduction of [2- 14 C]acetate into leaves of Dioscorea deltoidea, a radioactive furonanalog of deltafolin - protodeltofolin, containing two-thirds of the label in the 3-hydroxy-3-methylglutaryl portion - was isolated from them. Radioactive β-careotene and sterols were isolated from cut young leaves of Dioscorea 24 h after the introduction of [ 14 C] protodeltofolin into them, using chromatography on a column of silica gel and precipitation of sterols in the form of digitonins for this purpose. The incorporation of radioactivity from [ 14 C]-3-hydroxy-3-methyl-glutaric acid, bound in the form of a saponin, and β-carotene came to 0.18-0.80%, while incorporation into sterols came to 0.07-2.86% of the radioactivity of the alcohol extract. Thereby it was shown that 3-hydroxyl-3-methylglutaric acid, bound in the form of the saponin, can be used to form terpenoids in Dioscorea leaves. It was suggested that the binding of hydroxymethylglutaric acid to saponin represents one of the mechanisms of regulation of the rate of terpenoid biosynthesis in Dioscorea leaves

    Electrical conductivity is an indirect measurement of the quality of the steam supplied to power units. In the Los Azufres, Mich., geothermal field, the electrical conductivity once was measured in a discrete and periodic way by condensing steam samples through a water-cooled condenser. In an attempt to continuously measure conductivity, conductivity meters were installed where the units discharged, but the values proved unstable and unrepresentative. Thereafter, taking into account that steam quality should be measured at the steam delivery-reception point, equipment was designed and tested for continuously condensing steam. Finally it was possible to get an air-cooled condenser able to condense 500 milliliters per minute, enough to collect a representative flow of the steam and to measure its electrical conductivity. The equipment was installed in all seven back-pressure units operating in the field and to date has been operating in an optimal manner. [Spanish] La conductividad electrica es una medida indirecta de la calidad del vapor que se suministra a las unidades turbogeneradoras. En el campo geotermico de Los Azufres, Mich., la conductividad electrica se media en forma puntual y periodica, condensando muestras de vapor por medio de un serpentin enfriado con agua. Despues, ante la necesidad de medirla en forma continua, se instalaron conductivimetros en las descargas de las unidades, pero los valores resultaron muy inestables y poco representativos. Considerando, ademas, que la calidad del vapor debe medirse en el punto de entrega-recepcion, se disenaron y probaron equipos para condensar vapor de manera continua, lograndose construir un condensador enfriado por aire que logra condensar un flujo de 500 mililitros por minuto, cantidad suficiente para tener un flujo representativo del vapor que alimenta a las turbinas y medirle su conductividad electrica. Se instalaron estos equipos en las siete unidades turbogeneradoras a contrapresion que funcionan en el campo

    A clinical outcome tool is needed for the assessment of young athletes with low back pain. To translate and culturally adapt the Micheli functional scale (MFS), a self-report questionnaire developed to evaluate young athletes with low back pain (LBP) into Persian language and examine the reliability and validity of the Persian MFS (PMFS). A cross-sectional study was conducted to assess the psychometric properties of the PMFS. The PMFS was cross-culturally adapted into Persian language adopting forward/backward translation, expert panel review, and pre-testing. The PMFS was administered to young athletes with and without LBP. Main outcome measures were Persian MFS, Persian functional rating Index (PFRI), and visual analogue scale (VAS). A sample of 100 young athletes with LBP with a mean age of 16.5 ± 2.5 years participated. Fifty young athletes without LBP completed the PMFS. There was no missing responses and floor or ceiling effects. There was a significant difference for the total PMFS scores between young athletes with and without LBP. A significant correlation was found between the total PMFS score and the VAS (r = 0.92) or the PFRI (r = 0.82; P Persian MFS is valid and reliable for use in Persian-speaking young athletes with LBP.

    A previous tracer study in the Maritaro-La Cumbre area of the Los Azufres, Mich., geothermal field concluded that injection in well Az-15 recharges a group of producing wells located east of the injector to a maximum distance of about 2000 m. The study also indicated injection in Az-15 either does not recharge wells farther east in the neighborhood of the Laguna Verde fault, or does so at very low rates over a long period. Because it is important to recharge this zone, it was decided to explore the possibility of doing it by injecting in well Az-64, located in the area. Thus the present study was designed. Six producing wells were chosen to monitor tracer arrivals. Because all the chosen wells produce steam (several also produce water) and for economic reasons, it was decided to use a steam-phase tracer. We chose sulfur hexafluoride (SF6), a tracer successfully used before in the field. On October 24, 2006, we injected 96.4 kg of SF6 into well Az-64. All six chosen wells were sampled for 156 days, starting the day of injection. The tracer was detected in all six wells and for every well the shape of the residence curve clearly depicted the fractured nature of the corresponding permeability. Again in every case, the recovery curves indicated recovery was completed within the 156-day sampling period. The largest recoveries were in wells Az-05 (48.5%) and Az-43 (1.27%), those closest to the injection well and on the same side of the Maritaro fault as Az-64. Well Az-51, lying at 848 m from the injector and farthest away, registered the third-highest recovery percentage (1.01 x 10-5%), significantly higher than well Az-19 (6.95 x 10-6%), located 490 m from the injector; the two wells are on the same side of the Maritaro fault as Az-64. Well Az-32, located 423 m from the injector, but on the other side of the Maritaro fault, recovered 5.6 x 10-7% of the injected tracer, comparable to 8.67 x 10-7%, the amount recovered in well Az-13 on the same side of the Maritaro fault

El analisis de los datos comprendio las estimaciones de cloruros en las descargas totales, temperaturas de yacimiento, exceso de vapor en los fluidos de alimentacion, las concentraciones de CO{sub 2} en las descargas totales y en la fase liquida del yacimiento y las saturaciones de liquido en la formacion. Con los resultados se elaboraron mapas de isovalores de los parametros mencionados correspondientes a 2006 y 2007 para investigar su evolucion con respecto a los mapas obtenidos en 2005, asi como su relacion con las historias de reinyeccion. Se correlacionaron las composiciones isotopicas de los fluidos incluyendo los de reinyeccion para estimar efectos de mezcla de fluidos. Los resultados indican que las variables estudiadas responden a las tasas de reinyeccion en el campo. Las relaciones {delta}D vs {delta}18 O indican que un buen numero de pozos del campo producen diferentes proporciones de retornos de reinyeccion; en la zona norte los pozos AZ-65D, AZ-13, AZ-32, AZ-9A, AZ-9AD, AZ-28A, AZ-69D y AZ-44 producen una mayor proporcion mientras que los pozos AZ-5, AZ-28 y AZ-19 entre otros, producen una menor proporcion. En la zona sur los pozos AZ-2A, AZ-16AD, AZ-46 y AZ-33 producen relativamente altas proporciones de retornos de reinyeccion mientras que los pozos AZ-34, AZ-36 y AZ-37 producen menores proporciones. La distribucion de saturaciones de liquido hallada en 2007 muestra que las areas de maxima saturacion han disminuido con respecto a las distribuciones de este parametro en 2005 y 2006. En 2007 las saturaciones maximas de liquido se localizaron alrededor de los pozos AZ-22 y AZ-23 (zona sur) y AZ-28, AZ-32, AZ-45 y AZ-48 (zona norte), mientras que las saturaciones minimas se localizaron en

    Full Text Available Between 1938 and 1945, approximately 2.200 Austrians could flee from nationalsocialist persecution to Argentina. This article presents and analyses testimonies acquired through an oral history research project in Buenos Aires, with a focus on role and meaning of the passage and the sea voyage in these life stories. After time-consuming preparations, economic and bureaucratic struggles, violent persecution and nearly complete deprivation, the departure from Vienna and the separation from their former “Heimat” confirmed for these Austrian Jews a definite breach with their previous lives and the beginning of a stage of uncertainty and insecurity, in anxiety for the relatives they left behind. The transatlantic journey itself symbolizes a world in-between. On the one hand all emigrants had to pass through this transition under similar circumstances, but on the other hand the testimonies show a wide variety of experiences, depending on the individual situation, on the experiences made since the “Anschluss”, on the moment of escape and on the accommodation on board. The prospect of having to start from zero in a new country, without knowledge of the language, without housing and income, characterises the atmosphere of the testimonies, torn between the relief of escape from state repression and the uncertainty of the future. The “leisure time” during the journey which lasted three to four weeks offered an opportunity to look ahead and make plans for the future, but also to look back to the past and to consider the memoirs of a former existence. At the same time, some felt the need to enjoy the voyage and to try and forget their sorrows in this short period between departure and arrival. The interviewed persons were children, teenagers, or young adults when they were expelled. In order to give an insight into the experiences of the elder generations as well, I will quote from a private correspondence between family members written on the ship between Hamburg and Santa Fé. This essay also considers the Argentinian policies regarding immigration during the 1930s and 1940s, the different routes and embarking ports of escape, and finally reports about the arrival and the first impressions of the city of Buenos Aires.

    Full Text Available In 1786 in Rome, Johann Wolfgang Goethe wrote about him: “He is my younger brother; we art cut from the same mould. However, fate was against him, whereas I was fortune’s favourite.” He meant Karl Phillip Moritz (1756-1793, a German writer and art critic, Greek mythology historian, precursor of modern psychology and the author of psychological novel. If we assume that Goethe’s comments concern Moritz’s material and social status only, we would have to admit that Goethe was right. However, if we apply these judgments to the quality of his (Moritz’s works, we would be inclined to saying that in this case the great Goethe was wrong. In his aesthetic, Moritz is far more interesting and progressive than his “elder brother”; in his literary criticism – more consistent than Schiller, and in perceiving society and politics – more radical than Kant. This article is mainly on key concept regarding Moritz’s aesthetic works: the concept of beauty and its functionalism. Definition of “the work of art” as a closed, specified unity enables Moritz to get out of the frame of aesthetics itself and to enter the sphere of politics. Moritz liberates man from the restraints of utility and treats him as a noble individual who possesses the artistic value in himself.

The mean arterial pressure (MAP level (P = 0.002 and the incidence of limb movement disorder (P = 0.000 were significantly higher in patients with MICH than those with SICH. Basal ganglia and thalamus were the predilection sites of hematoma (P = 0.001. Patients with MICH had worse prognosis compared to those with SICH 3 months after onset (P = 0.006. Conclusions Hypertension > 5 years, diabetes mellitus, hypercholesterolemia and ischemic stroke were identified to be the pathophysiological basis of MICH in this study. All patients with MICH had more serious clinical manifestations after onset and worse prognosis. DOI: 10.3969/j.issn.1672-6731.2016.01.008

    2006-01-01

    Aqueous extracts of three medicinal plants used in Malaysian traditional medicine for the treatment of diabetes were investigated. The nuts of Areca cathecu, leaves of Lagerstroemia speciosa and Ficus deltoidea were each extracted by boiling in distilled water. The aqueous extracts were filtered and the filtrates were then spray dried. Their biological evaluation was conducted to determine their blood glucose lowering effect in normoglycaemic and alloxan-induced diabetic rats. Commercially available antidiabetic drug, glybenclamide was used as positive control. Toxicity of the extracts was carried out using the brine shrimp lethality assay and in vivo acute toxicity test in rats. Aqueous extracts of all the plants studied showed significant reduction in blood glucose level up to 50% in rats over a period of 3 to 4 weeks. The largest reduction in blood glucose levels was exhibited by the aqueous extracts of the Lagestroemia speciosa, followed by the Ficus deltoidea and Areca cathecu. There was no evidence of toxicity of the extracts against the brine shrimp (up to 4,000 μg/ml) and in rats (up to 0.2% body weight). (Author)

They are some regular trends of secondary metabolites synthesis in the plant cell culture:It can be noted the stable synthesis of the compound promoting cell proliferation. Indeed, cell cultures of Dioscorea deltoidea were demonstrated to accumulate only furostanol glycosides, which promoted cell division. Furostanol glycoside content of Dioscorea strain DM-0.5 was up to 6 - 12% by dry biomass.Panax ginseng and P. japonicus plant cell cultures synthesize as minimum seven triterpene glycosides (ginsenosides, the productivity of these compounds was up to 6.0 - 8.0% on dry biomass.By contrast, the detectable synthesis of diterpene steviol-glycosides in cultivated cells of Stevia rebaudiana initiated in the mixotrophic cultures during chloroplast formation only.Despite these differences, or mainly due to them, plant cell cultures have become an attractive source of phytochemicals in alternative to collecting wild plants.

  13. Plant life forms in thermal regulation and self purification of urban housing environments

    Energy Technology Data Exchange (ETDEWEB)

    Raza, S H [Osmania Univ., Ecology and Environmental Studies Div., Hyderabad (India)

    1995-12-01

    This article is concerned with the air quality of the closed indoor environment with respect to its temperature and carbon dioxide levels and with the assessment of management practices that have been used to reduce temperature and carbon dioxide levels with the help of certain plants. Phanerophytic lifeforms, such as trees, shrubs, herbs and creepers surrounding dwellings can be shown to produce a cooling effect, reducing temperatures by up to 11{sup o}C. Certain succulent plants like Kalanchoe marmorata, Bryophyllum pinnata and Apicra deltoideae were observed under experimental conditions to reduce carbon dioxide levels up to 90% from closed chambers under dark conditions. Certain ornamental plants such as Verbena bipinnatifida and Ixora coccinea could remove 63-75% of carbon dioxide from closed indoor environments in the presence of light. (author) 3 tabs., 11 refs.

    Rhizoma coptidis is a broadly used traditional Chinese medicine (TCM). The investigation of the influence of species and geographical origins on the phytochemicals of R. coptidis is crucial for its reasonable application and quality control. Development of an effective method to systematically study the phytochemical variations of the rhizomes of three Coptis species (Ranunculaceae) (Coptis chinensis Franch, Coptis deltoidea C.Y. Cheng et Hsiao and Coptis teeta Wall.) and a species (i.e., C. chinensis) obtained from both Daodi and non-Daodi production regions. The three species had significant differences in their phytochemicals. The rhizome of C. chinensis contained more epiberberine (13.52 ± 2.65 mg/g), palmatine (18.20 ± 2.89 mg/g), coptisine (23.32 ± 4.27 mg/g) and columbamine (4.89 ± 1.16 mg/g), whereas the rhizomes of C. deltoidea and C. teeta showed the highest level of jatrorrhizine (8.52 ± 1.36 mg/g) and berberine (81.06 ± 4.83 mg/g), respectively. Moreover, the rhizome of C. chinensis from three Daodi production regions (Shizhu, Lichuan and Emeishan) contained more alkaloids than those from three non-Daodi production regions (Mianyang, Shifang and Zhenping). It is necessary to use the three R. coptidis species differentially in TCM clinical practice. Daodi C. chinensis medicinal materials have better quality than most non-Daodi ones, and so they should be preferred for TCM prescription. The combination of HPLC-based fingerprint analysis and quantification of multi-ingredients with statistical analysis provided an effective approach for species discrimination and quality evaluation of R. coptidis.

    This essay traces my engagement with Michèle Grossen’s ideas of a dialogical perspective on interaction analysis (Grossen Integrative Psychological and Behavioral Science, 1–22, 2009) and highlights a process account of self in interaction. Firstly I draw on Turner’s concept of liminality......, in particular with interactional asymmetries of interaction, whilst relativising the I-position dialogical perspective. I explore insights from social anthropology as well as revisiting conversation analysis and discursive psychology, concluding that a promising direction would be sought through a cross......-fertilisation between dialogism and other sibling perspectives concerning language use, communication, social action and discourse- and narrative-based analyses....

    Luther’s translation of Psalm 22:22 reads: "Deliver me from the unicorns" (errette mich von den Einhömem). This translation arouses curiosity for it is common knowledge that the unicorn has never existed but yet figures as a prominent symbol of the New Age. Besides, the Hebrew word means antelope, buffalo, or wild bull. The question thus arises why the Hebrew re'em was translated by Luther with unicorn While the official Dutch translation of 1633 (Statenvertaling, translated according t...

    We report on an indirect study of solar activity by using the Forbush effect which consists on the anti-correlation between the intensity of solar activity and the intensity of secondary cosmic radiation detected at ground level at the Earth. We have used a cylindrical water Cherenkov detector to measure the rate of arrival of secondary cosmic rays in Morelia Mich., Mexico, at 1950 m.a.s.l. We describe the analysis required to unfold the effect of atmospheric pressure and the search for Forbush decreases in our data, the latter correspond to more than one year of continuous data collection.

    Full Text Available Durante un año y medio se investigó el ritmo de crecimiento y la longevidad de follaje de 22 especies abundantes del estrato arbustivo en el bosque tropical premontano de la Reserva Biológica Alberto Ml. Brenes, Provincia Alajuela, San Ramón, Costa Rica. Se distinguieron y describieron tres tipos de brotación de las hojas. Una gran cantidad de las especies, especialmente las monocotiledóneas, brotan hojas nuevas en intervalos determinados contínuamente durante todo el año, en efecto parte de las plantas muestran una producción de hojas más lenta en la estación seca. Esta frecuencia de brotación, es decir el intervalo entre el desarrollo de dos hojas siguientes, varía entre las especies investigadas entre 17-22 días y más de medio año. La longevidad de follaje promedio de las plantas investigadas varía entre medio y cuatro años. Se estimó que la edad máxima de hojas de las palmas Cryosophila warscewiczii, Iriartea deltoidea y Calyptrogyne trichostachys es más de cinco años. Generalmente, en sitios más secos y más oscuros, la frecuencia de brotación fue más larga y la longevidad de follaje más alta. Esta relación fue significante en algunos casos, pero muestra que aunque las diferencias microclimáticas son muy pequeñas, el crecimiento varía entre diferentes sitios en el bosque. Además, los datos muestran que aunque el clima en el sotobosque premontano muy húmedo es relativamente constante, algunas especies muestran una estacionalidad del ritmo de crecimiento.During one and a half years (February 1991 - July 1992 the growth rhythm and the longevity of leaves of 22 abundant understory species in the tropical premontane rain forest of Reserva Biológica Alberto Ml.

    The U.S. Geological Survey, in cooperation with the Lenawee County Conservation District in Lenawee County, Mich., conducted a sampling effort over a single growing season (June to November 2007) to evaluate the microbiological water quality around a novel livestock reservoir wetland sub-irrigation system. Samples were collected and analyzed for fecal coliform bacteria, Escherichia coli (E. coli) bacteria, and six genes from pathogenic strains of E. coli.A total of 73 water-quality samples were collected on nine occasions from June to November 2007. These samples were collected within the surface water, shallow ground water, and the manure-treatment system near Bakerlads Farm near Clayton in Lenawee County, Mich. Fecal coliform bacteria concentrations ranged from 10 to 1.26 million colony forming units per 100 milliliters (CFU/100 mL). E. coli bacteria concentrations ranged from 8 to 540,000 CFU/100 mL. Data from the E. coli pathogen analysis showed that 73 percent of samples contained the eaeA gene, 1 percent of samples contained the stx2 gene, 37 percent of samples contained the stx1 gene, 21 percent of samples contained the rfbO157 gene, and 64 percent of samples contained the LTIIa gene.

Los usos se agruparon en ocho categorías de uso y 30 subcategorías; las categorías de uso más importantes fueron construcción, utensilios y herramientas, y alimentación humana. Las especies que registraron mayor número de usos fueron Bactris gasipaes, Astrocaryum standleyanum, Oenocarpus bataua, Euterpe oleracea, Oenocarpus minor, Cocos nucifera, Attalea cuatrecasana, Iriartea deltoidea, Desmoncus cirrhifer y Wettinia quinaria.

  20. Remote Sensing of Sonoran Desert Vegetation Structure and Phenology with Ground-Based LiDAR

    Full Text Available Long-term vegetation monitoring efforts have become increasingly important for understanding ecosystem response to global change. Many traditional methods for monitoring can be infrequent and limited in scope. Ground-based LiDAR is one remote sensing method that offers a clear advancement to monitor vegetation dynamics at high spatial and temporal resolution. We determined the effectiveness of LiDAR to detect intra-annual variability in vegetation structure at a long-term Sonoran Desert monitoring plot dominated by cacti, deciduous and evergreen shrubs. Monthly repeat LiDAR scans of perennial plant canopies over the course of one year had high precision. LiDAR measurements of canopy height and area were accurate with respect to total station survey measurements of individual plants. We found an increase in the number of LiDAR vegetation returns following the wet North American Monsoon season. This intra-annual variability in vegetation structure detected by LiDAR was attributable to a drought deciduous shrub Ambrosia deltoidea, whereas the evergreen shrub Larrea tridentata and cactus Opuntia engelmannii had low variability. Benefits of using LiDAR over traditional methods to census desert plants are more rapid, consistent, and cost-effective data acquisition in a high-resolution, 3-dimensional context. We conclude that repeat LiDAR measurements can be an effective method for documenting ecosystem response to desert climatology and drought over short time intervals and at detailed-local spatial scale.

    Full Text Available Se caracterizaron la diversidad, estructura horizontal y vertical de la vegetación arbórea y arbustiva en cacaotales tradicionales y bosque maduro. Se evaluó la diversidad alfa, beta y se identificaron relaciones entre la riqueza con la estructura de la vegetación arbórea. El bosque registró los mayores valores en riqueza de especies, abundancia y estructura, seguido por el sistema agroforestal tradicional con cacao semilla. Las especies más importantes ecológicamente en el bosque fueron Iriartea deltoidea y Otoba glycycarpa. En todos los sistemas agroforestales tradicionales fueron Cordia alliodora y Cedrela odorata. En los sistemas agroforestales con cultivo de cacao la riqueza de especies se correlaciona positivamente con la densidad y área basal, marcando dependencia directa entre estas variables. Este resultado no puede generalizarse ya que en el bosque maduro y sistema agroforestal de subsistencia no se registran estas dependencias. Esto posiblemente es explicado por la discetaniedad, tamaños de vegetación y distribución aleatoria de los individuos sobre la riqueza de especies. Se concluyó que el bosque maduro y el sistema agroforestal con cacao semilla son los sistemas más importantes para conservación de especies arbóreas y arbustivas, según la riqueza, diversidad, índices de similitud y estructura de la vegetación.

  3. In vitro antimicrobial activity of ethanolic extracts obtained from Ficus spp. leaves against the fish pathogen Aeromonas hydrophila

    Full Text Available The main goal of this study was to determine in vitro antimicrobial activity of ethanolic extracts obtained from the leaves of various Ficus species against Aeromonas hydrophila isolated locally from infected rainbow trout (Oncorhynchus mykiss Walbaum with the aim of providing scientific rationale for the use of the plant in the treatment of bacterial infections induced by Aeromonas spp. in fish. Antimicrobial susceptibility testing was done on Muller-Hinton agar with the disc diffusion method. In the present study, most ethanolic extracts proved effective against the A. hydrophila tested, with 10-12 mm inhibition zones observed. A. hydrophila demonstrated the highest susceptibility to F. pumila. Among various species of Ficus with moderate activity against A. hydrophila, the highest antibacterial activities were noted for F. benghalensis, F. benjamina, F. deltoidea, F. hispida, and F. lyrata. Thus, Ficus can be used as a natural antiseptic and antimicrobial agent in veterinary practice. Further investigations need to be conducted to isolate and identify the bioactive compounds that can then be subjected to detailed pharmacological studies and the development of clinical applications. The alarming rate of increasing resistance in bacterial pathogens in aquaculture environments means that medicinal plants with antibacterial properties are very important as natural resources of new active compounds.

    Die Zeit ist ein großer Lehrmeister! Das Dumme ist nur, dass sie auf Dauer alle ihre Schüler tötet. (nach Hector Berlioz) „Solange mich niemand fragt, weiß ich, was Zeit ist“, hat der Heilige Augustus gesagt. Damit ist er fast modern, denn die Quantenphysiker behaupten sogar, „Zeit, das gibt es gar nicht!“ Je genauer man es wissen will, desto komplizierter wird das mit der Zeit: Ist die Zeit wirklich eine vierte Dimension, ähnlich wie ein Raum oder „fließt“ sie sozusagen nur dahin? Und wenn sie fließt, kann man dann sagen, wie schnell? Gibt es die Zukunft? Sind Zeitreisen möglich? Und warum scheint die Zeit sich nur in eine Richtung zu bewegen. Schwierige Probleme: aber hier, wie immer in dieser Reihe, seriös, leicht und locker erklärt.

    Leonor Michaelis spent the years of 1922-1926 as Professor of Biochemistry of the Aichi Medical College (now Graduate School of Medicine, Nagoya University) in Nagoya, Japan. Michaelis succeeded in gathering many bright young biochemists from all over Japan into his laboratory, and made tremendous contributions to the promotion of biochemistry in Japan. Michaelis was invited to many places in Japan to present lectures over those years. Kunio Yagi, who was Professor of Biochemistry at Nagoya University in the second half of the 20th century, succeeded in crystallizing the "Michaelis" enzyme-substrate complex. Historically, Michelis has had an enormous impact on biochemistry in Japan. Copyright © 2013 Federation of European Biochemical Societies. Published by Elsevier B.V. All rights reserved.

  9. The use of analogy in pro-life argumentation

    Directory of Open Access Journals (Sweden)

    Simona Mazilu

    2012-11-01

    Full Text Available The paper is concerned with how analogy is strategically used in pro-life argumentation on abortion. Pragma-dialectics (van Eemeren and Grootendorst 1992 offers a set of critical questions by means of which I will evaluate the use of the argumentation based on a relation of analogy in terms of dialectical soundness. Examining various pro-life texts, I have noticed that the analogies employed remain unexplained. Therefore, despite the apparent similarities between abortion and the German holocaust or slavery, for instance, there are essential differences which are not mentioned. I claim that these analogies mainly have a rhetorical function, to operate what has been called by Micheli (2007: 960 “a transfer of emotional consensus”.

    The LHC main magnet system includes about 600 superconducting quadrupoles for beam focusing. Superconducting Matching Quadrupole Magnets (MQMs) are just one of several varieties of quadrupole; they will be installed in the accelerator´s eight ´insertion zones´, four of which are also experimental areas, where the beams will intersect to produce proton-proton collisions. The first MQM, built by the UK firm Tesla Engineering, has passed its acceptance tests. The team responsible for the tests is pictured here with the 3.5-metre-long magnet.

    Aspergillus fumigatus Friesen, Sporotrichum sp., Thermoascus aurantiacus Miche and Torula thermophila Cooney and Emerson were able to degrade filter paper to an appreciable extent. Absidia corymbifera (Cohn) Saccardo et Trotter, Rhizopus microsporus van Tieghem and R. rhizopodiformis (Cohn) Zopf could not degrade filter paper though they were able to grow on the media supplied. The fungi able to degrade filter paper were also capable of elaborating extracellular cellulase and produced sufficient hydrolysis of carboxymethyl cellulose. The Cx enzyme was stable at 45 degrees C for 25 days. An incubation period of 15 to 25 days was sufficient not only to degrade CMC but even more complex substrates, such as jute, cotton and filter paper. The cellulases of these fungi were inductive in nature. (Refs. 11).

    1993-01-01

    Less than three weeks after the coup against Communist Party General Secretary Mikhail Gorbachev that eventually led to the disbanding of the Soviet Union, a technical delegation from the US entered the newly renamed city of St. Petersburg. The delegation visited manufacturing facilities and welding institutions that were changing from central control to a local decentralized operation and that were unsure of what would be the government's role in their operations. Plans for the trip began at the AWS Welding Show in Detroit, Mich., in April 1991, when in-depth discussions were held with Deputy Director Sergey Kuchuk-Yatsenko of the E.O. Paton Electric Welding Institute, Kiev, Ukraine. A summary of the trip is given in this paper

    In March 2004 was accepted in the site of Gran Telescopio Canarias (GTC) in La Palma Island, Spain, the Commissioning Instrument (CI) for the GTC. During the GTC integration phase, the CI will be a diagnostic tool for performance verification. The CI features four operation modes-imaging, pupil imaging, Curvature Wave-front sensing (WFS), and high resolution Shack-Hartmann WFS. This instrument was built by the Instituto de Astronomia UNAM in Mexico City and the Centro de Ingenieria y Desarrollo Industrial (CIDESI) in Queretaro, Qro under a GRANTECAN contract after an international public bid. Some optical components were built by Centro de Investigaciones en Optica (CIO) in Leon Gto and the biggest mechanical parts were manufactured by Vatech in Morelia Mich. In this paper we made a general description of the CI and we relate how this instrument, build under international standards, was entirely made in Mexico.

    1990-01-01

    During a radon gas screening program, elevated levels of radon gas were detected in homes on Mackinac Island, Mich. Six homes on foundations with crawl spaces were selected for a research project aimed at reducing radon gas concentrations, which ranged from 12.9 to 82.3 pCi/l. Using isolation and ventilation techniques, and variations thereof, radon concentrations were reduced to less than 1 pCi/l. This paper reports that these reductions were achieved using 3.5 mil cross laminated or 10 mil high density polyethylene plastic as a barrier without sealing to the foundation or support piers, solid and/or perforated plastic pipe and mechanical fans. Wind turbines were found to be ineffective at reducing concentrations to acceptable levels. Homeowners themselves installed all materials

    Commercial-steam production in the southern area of Los Azufres, Mich., Mexico, Geothermal Field began in 1982 with the operation of Unit 2, the backpressure 5-MW unit, and continued in 1988 when the 50-MW condensing Unit 7 was commissioned. Today to supply steam to Unit 7, it is necessary to gather steam from 15 production wells, amounting 450 tons per hour (t/h) under operating conditions. During maintenance periods for Unit 7, production wells are removed from the steam-supply system but continue producing steam that is discharged to the atmosphere-a loss affecting the economic life of the geothermal reservoir. Therefore several actions have been proposed and tried to save the steam and preserve the geothermal resource. This paper presents the results of the actions and the technical and economic benefits obtained from them. [Spanish] La produccion de vapor con fines comerciales en la zona sur del campo geotermico de Los Azufres, Mich., Mexico, empezo en 1982 con la puesta en marcha de la Unidad 2 de 5 MW a contrapresion, para continuar en 1988 con la Unidad 7 de 50 MW a condensacion. Para cumplir con el suministro de vapor a la U-7, a la fecha es necesario integrar la produccion de 15 pozos productores, que producen un total de 450 toneladas por hora (t/h) a condiciones de operacion. Durante los periodos de mantenimiento de la U-7 los pozos son desintegrados del sistema de suministro, pero continuan produciendo vapor, el cual es descargado a la atmosfera sin ningun provecho, lo que representa una perdida que afecta la vida util del yacimiento geotermico. Por ello se han propuesto y aplicado diversas acciones operativas en cada uno de esos pozos con el objetivo de ahorrar vapor y preservar el recurso geotermico. En este trabajo se presentan los resultados de esas acciones y los beneficios tecnicos y economicos obtenidos.

    The 100th anniversary of the first description of paroxysmal nocturnal hemoglobinuria by Paul Strübing presents an opportunity to analyze the premises valid for the description of this disease in addition to an attempt at an extensive pathophysiological analysis. Strübing's two papers of 1882 were way ahead of his time, when pathophysiology was just at its beginning, particularly considering the fact that neither Marchiafava, who is still commonly credited wit the first description of this disease (1911) and its recognition as a clinical entity (1928), nor his student Micheli analyzed the PNH syndrome in pathophysiological terms as carefully as Strübing. Both of the former names were given to the disease, which is generally referred to as the Marchiafava-Micheli Anemia. William Crosby, who in 1951 in a historical review of PHN first pointed out the pioneering achievement of Strübing, suggested that it was mainly due to the lack of the right "intellectual climate" at the time that so little attention was paid to his work. Still another important aspect of the early history of PNH will be described in the present paper. The analysis of Strübing's publications leads to the conclusion that he was only able to make his important contribution to medical science because he not only had the appropriate clinical setting but also the scientific backup of the famous physiologist Leonhard Landois and his institute at the University of Greifswald, which is an excellent example of scientific progress through cooperation between a clinician and a research scientist.

    Full Text Available Treatment with the usual antimalarial drugs, have induced parasite resistance, reinforcing the need to finding natural antimalarial components that would be found on plants from the forest. Therefore, we decided to look for these components in Costa Rican plants from a protected forest area. Fresh and dry extracts of roots, bark, leaves, flowers and fruits of 25 plants from a biological reserve in Costa Rica, Reserva Biológica Alberto Manuel Brenes (REBAMB, were studied in vitro for the presence of substances with antimalarial activity. By studying the inhibition of P. berghei schizogony, we assessed the antimalarial activity of several plant extracts: Aphelandra aurantiaca, A. tridentata (Acanthaceae; Xanthosoma undipes (Araceae; Iriartea deltoidea (Arecaceae; Neurolaena lobata (Asteraceae; Senna papillosa, Pterocarpus hayessi, Lonchocarpus pentaphyllus (Fabaceae; Nectandra membranacea, Persea povedae, Cinamomum chavarrianum (Lauraceae; Hampea appendiculata (Malvaceae; Ruagea glabra, Guarea glabra (Meliaceae; Psidium guajava (Myrtaceae; Bocconia frutescens (Papaveraceae; Piper friedrichsthalii (Piperaceae; Clematis dioica (Ranunculaceae; Prunus annularis (Rosaceae; Siparuna thecaphora (Siparunaceae; Solanum arboreum, Witheringia solanácea (Solanaceae; Ticodendrum incognitum (Ticodendraceae; Heliocarpus appendiculatus (Tiliaceae and Myriocarpa longipes (Urticaceae. We used different parts of the plants as well as fresh and dried extracts for testing IC50. The solid content of the extracts ranged from 1-71.9μg/mL. The fresh extracts showed stronger activity than the dry ones. Since the plants showing the strongest antimalarial activity are very common in Central America, and some similar genera of these plants have shown positives results in South America, we considered important to present these findings for discussion. On the other hand, this is the first systematic study of this kind ever realized in a circumscribed and protected area of

    Full Text Available Scatter hoarding of seeds by animals contributes significantly to forest-level processes, including plant recruitment and forest community composition. However, the potential positive and negative effects of caching on seed survival, germination success, and seedling survival have rarely been assessed through experimental studies. Here, I tested the hypothesis that seed burial mimicking caches made by scatter hoarding Central American agoutis (Dasyprocta punctate enhances seed survival, germination, and growth by protecting seeds from seed predators and providing favorable microhabitats for germination. In a series of experiments, I used simulated agouti seed caches to assess how hoarding affects seed predation by ground-dwelling invertebrates and vertebrates for four plant species. I tracked germination and seedling growth of intact and beetle-infested seeds and, using exclosures, monitored the effects of mammals on seedling survival through time. All experiments were conducted over three years in a lowland wet forest in Costa Rica. The majority of hoarded palm seeds escaped predation by both invertebrates and vertebrates while exposed seeds suffered high levels of infestation and removal. Hoarding had no effect on infestation rates of D. panamensis, but burial negatively affected germination success by preventing endocarp dehiscence. Non-infested palm seeds had higher germination success and produced larger seedlings than infested seeds. Seedlings of A. alatum and I. deltoidea suffered high mortality by seed-eating mammals. Hoarding protected most seeds from predators and enhanced germination success (except for D. panamensis and seedling growth, although mammals killed many seedlings of two plant species; all seedling deaths were due to seed removal from the plant base. Using experimental caches, this study shows that scatter hoarding is beneficial to most seeds and may positively affect plant propagation in tropical forests, although

    Permanent vegetation plots in the northern Sonoran Desert, USA, provided an opportunity to assess the effects of recent drought on desert shrubs and to examine survival in relation to rainfall variability during the past 76 years. Survival and maximum longevity of six species were determined for eight intercensus periods between 1928 and 2004. Average annual survival was Ambrosia deltoidea, 0.9167 ?? 0.0415; Encelia farinosa, 0.7952 ?? 0.0926; Janusia gracilis, 0.9334 ?? 0.0247; Krameria grayi, 0.9702 ?? 0.0270; Larrea tridentata, 0.9861 ?? 0.0174; and Lycium berlandieri, 0.9910 ?? 0.0077. The longest-lived species were Larrea, Lycium, and Krameria, with average maximum life spans of 330, 211, and 184 years. Janusia, Ambrosia, and Encelia were much shorter lived, with average maximum longevity of 53, 40, and 16 years. Winter rain equalled or exceeded 90% of the long-term average accumulation except during 1948 to 1959 (65% of average) and from 2001 to 2003 (49% of average). Summer rain did not drop below 90% of the average accumulation in any period. The 1950s drought caused modest declines in survival of Ambrosia, Encelia, Janusia, Krameria, and Lycium. The effects of the recent drought were much more pronounced, resulting in sharp declines in survival and maximum longevity of Ambrosia, Encelia, Krameria, and Larrea, and modest declines for Lycium. Despite heightened mortality during the recent severe drought, 72% of the deaths observed between 1928 and 2004 occurred during periods of average or better-than-average rain, providing support for the idea that demography of shrubs in arid regions is influenced by continuous as well as episodic processes.

    Full Text Available Con el fin de obtener un diagnóstico del estado actual de conocimiento sobre usos de las palmas en la Amazonia colombiana, se revisaron las principales fuentes de información. Treinta y seis de las 41 etnias indígenas consideradas tuvieron registros de uso. Se registraron 82 especies de palmas usadas (78% de las potenciales y 165 usos distribuidos en ocho categorías; todos los usos se presentan de manera detallada en un catálogo. Las categorías de uso más importantes fueron: utensilios y herramientas, construcción, y alimentación humana. Las diez especies más importantes fueron Bactris gasipaes, Euterpe precatoria, Mauritia flexuosa, Oenocarpus bataua, Attalea maripa, Oenocarpus minor, Astrocaryum chambira, Iriartea deltoidea, Oenocarpus bacaba y Socratea exorrhiza; la mayoría de ellas también han sido registradas como las más importantes en otras partes del Neotrópico. No se encontró ninguna información sobre usos de palmas para varios grupos indígenas, especialmente para las etnias cocama, letuama, piaroa, pisamira y yurí, para las cuales se requieren investigaciones detalladas. Se concluye que a pesar de los vacíos de información, los resultados muestran que las palmas son un recurso muy importante con un gran potencial, y una pieza fundamental para la seguridad alimentaria y el desarrollo sustentable de la Amazonia colombiana. Sugerimos la inclusión de las especies más importantes en programas de manejo y agroforestales, al igual que la implementación y popularización de técnicas de cosecha no destructivas. Recomendamos además que las investigaciones futuras estén enfocadas en desarrollar estrategias de manejo que garanticen el uso sostenible de todas estas especies útiles.

Cheng et Hsiao and Coptis teeta Wall. Quantitative determination of protoberberine alkaloids in R. coptidis is critical for controlling its quality. In this study, a rapid, simple and accurate quantitative 1 H NMR (qNMR) method was developed for simultaneous determination of berberine, jatrorrhizine, epiberberine, coptisine, palmatine and columbamine in R. coptidis from the three species. Method validation was performed in terms of selectivity, precision, repeatability, stability, accuracy, robustness and linearity. The average recoveries obtained were in the range of 96.9–102.4% for all the six alkaloids. In addition, the qNMR data were analyzed with analysis of variance (ANOVA), hierarchical clustering analysis (HCA) and principal component analysis (PCA), and the results showed that the contents of the active alkaloids have significant difference among the three species. Compared with the conventional HPLC approach, the proposed qNMR method was demonstrated to be a powerful tool for quantifying the six alkaloids due to its unique advantages of high robustness, rapid analysis time and no need of standard compounds for calibration curves preparation. These findings indicate that this method has potential as a reliable method for quality evaluation of herb medicines, especially for protoberberine alkaloid-containing ones.

    Coptidis rhizoma (CR) is the dried rhizome of Coptis chinensis Franch., C. deltoidea C. Y. Cheng et Hsiao or C. teeta Wall. (Ranunculaceae) and is commonly used in Traditional Chinese Medicine for the treatment of various diseases including bacillary dysentery, typhoid, tuberculosis, epidemic cerebrospinal meningitis, empyrosis, pertussis, and other illnesses. A literature survey was conducted via SciFinder, ScieneDirect, PubMed, Springer, and Wiley databases. A total of 139 selected references were classified on the basis of their research scopes, including chemical investigation, quality evaluation and pharmacological studies. Many types of secondary metabolites including alkaloids, lignans, phenylpropanoids, flavonoids, phenolic compounds, saccharides, and steroids have been isolated from CR. Among them, protoberberine-type alkaloids, such as berberine, palmatine, coptisine, epiberberine, jatrorrhizine, columamine, are the main components of CR. Quantitative determination of these alkaloids is a very important aspect in the quality evaluation of CR. In recent years, with the advances in isolation and detection technologies, many new instruments and methods have been developed for the quantitative and qualitative analysis of the main alkaloids from CR. The quality control of CR has provided safety for pharmacological applications. These quality evaluation methods are also frequently employed to screen the active components from CR. Various investigations have shown that CR and its main alkaloids exhibited many powerful pharmacological effects including anti-inflammatory, anti-cancer, anti-diabetic, neuroprotective, cardioprotective, hypoglycemic, anti-Alzheimer and hepatoprotective activities. This review summarizes the recent phytochemical investigations, quality evaluation methods, the biological studies focusing on CR as well as its main alkaloids.

    Full Text Available Cardiovascular diseases (CVDs are among the leading causes of morbidity and mortality in both the developed and developing world. Rhizoma coptidis (RC, known as Huang Lian in China, is the dried rhizome of medicinal plants from the family Ranunculaceae, such as Coptis chinensis Franch, C. deltoidea C.Y. Cheng et Hsiao, and C. teeta Wall which has been used by Chinese medicinal physicians for more than 2000 years. In China, RC is a common component in traditional medicines used to treat CVD associated problems including obesity, diabetes mellitus, hyperlipidemia, hyperglycemia and disorders of lipid metabolism. In recent years, numerous scientific studies have sought to investigate the biological properties of RC to provide scientific evidence for its traditional medical uses. RC has been found to exert significant beneficial effects on major risk factors for CVDs including anti-atherosclerotic effect, protection from myocardial ischemia-reperfusion injury, lipid-lowering effect, anti-obesity effect and anti-hepatic steatosis effect. These properties have been attributed to the presence of bioactive compounds contained in RC such as berberine, coptisine, palmatine, epiberberine, jatrorrhizine and magnoflorine; all of which have been demonstrated to have cardioprotective effects on the various parameters contributing to the occurrence of CVD through a variety of pathways. The evidence available in the published literature indicates that RC is a herb with tremendous potential to reduce the risks of CVDs, and this review aims to summarize the cardioprotective properties of RC with reference to the published literature which overall indicates that RC is a herb with remarkable potential to reduce the risks of CVDs.

    Full Text Available In illegal hunting it is often possible only on the basis of morphological characteristics to determine the animal species. By the method of comparison there was performed the forensic analysis of roe deer and sheep osteological features. For the purpose of investigating the shoulder blade (Scapula and shoulder bone (Humerus comparative characteristics, there were used 6 shoulder blades and 6 shoulder bones of roe deer and 8 shoulder blades and 8 shoulder bones of sheep. After the skin, muscles, arterial, venous and lymphatic vessels as well as nerves were removed from the bones, they were thermally treated in an autoclave. Subsequently, the bones were placed in 3% solutioin of hydrogen peroxide (H2O2 for bleaching and degreasing. Then they were air dried and then photographed. Shoulder blade (Scapula is a bone plate (Ossa plana roughly triangular in shape. Scapular spine (Spina scapulae is much more prominent in roe deer with acromion blade in the form of spike, while in sheep it is shorter and ends with acrimion at a right angle. Shoulder blade cup (Cavitas glenoidalis in roe deer is round in shape, and in sheep it is oval. Tuberculum supraglenoidale and Processus coracoideus in sheep are more and in roe deer less developed. Shoulder bone (Humerus in roe deer is relatively long, slender bone with proximal convexity turned cranially in regard to the same bone in sheep, which is stronger and heavier. Tuberculum majus in roe deer is less developed, and in sheep it is in a form of solid bone protuberance. Tuberculum minus and Tuberositas deltoidea in sheep are more developed than in roe deer. At medial condyle (Condylus medialis in sheep there is shallow and wide groove, while in roe deer it is deeper and narrower. On the basis of morphological differences of roe deer and sheep bones, it can be determined with certainty which animal spesies they belong to.

    West Bohemia is located at the suture of three mantle lithosphere plates, the Eger Rift, the Cheb basin and is the site of Quaternary volcanism. This complex tectonic setting results in localized, periodic earthquake swarms throughout the region and many CO2 springs and gas exhalation sites. Nový Kostel, the most active swarm area, experiences frequent swarms of several hundreds to thousands of earthquakes over a period of weeks to several months. It is a unique study area, since the swarm region is surrounded by the West Bohemia Seismic Network (WEBNET), providing observations in all directions. Larger swarms, such as those in 1985/1986, 1997, 2000, 2007 and 2008, have been studied in terms of source mechanisms and swarm characteristics (Fischer and Michálek, 2003; Fischer et al., 2010; Vavryčuk, 2011). The seismicity is always located in the same area and depth range (6-15 km), however the active fault planes differ. This indicates changes to the local stress field, and may relate to the complicated tectonic situation and/or migrating fluids. Many studies have examined individual swarms and compared the earthquake episodes, however the mechanisms behind the phenomenon are still not understood. This has motivated many studies, including recent proposals for a reflection seismic profile directly over the swarm area and multidisciplinary monitoring through ICDP. In this study, we image the velocity structure within and around the swarm area using double-difference tomography (Zhang and Thurber, 2003) and Weighted Average Model (WAM) post-processing analysis (Calò et al., 2011). The WAM analysis averages together velocity models calculated with a variety of reasonable starting parameters. The velocities are weighted by the raypath proximity and density at an inversion node. This reduces starting model bias and artifacts, and yields a weighted standard deviation at each grid point. Earthquake locations and WEBNET P and S arrival times for the two most recent large

To perform the analysis different tire pressures, pavement material properties and asphalt layer thicknesses were selected. Evaluation criteria used in the analysis were tensile strain in bottom of the asphalt layer, vertical compressive strain at the top of the subgrade and surface displacement. Results showed that FENL methods predicted more strain and surface deflection than the FEL and EL analysis methods. Analyzing pavements with FEL does not offer many advantages over the EL method. Differences in predicted strains between the three methods of analysis in some cases was found to be close to 100% It was suggested that these programs require more calibration and validation both theoretically and empirically to accurately correlate with field observations. 19 refs., 4 tabs., 9 figs.

    Full Text Available Der libertäre Paternalismus befürwortet Eingriffe in die Entscheidungsfindung von Bürgern, ohne ihnen Optionen völlig nehmen zu wollen. Vielmehr soll die Lenkung des Willens durch Schubser (nudges geschehen. Im folgenden Beitrag möchte ich zeigen, dass der libertäre Paternalismus auf tönernen Füßen steht. Ich bediene mich dabei des polemischen Bilds von Quacksalbern. Dieses Bild passt zu meinem argumentativen Vorgehen, da ich erstens zeigen will, dass der libertäre Paternalismus falsche Diagnosen über vermeintliche Krankheiten der Willensbildung stellt, und zweitens, dass er die falsche Therapie empfiehlt. Im ersten Teil des Artikels kritisiere ich die Diagnose des libertären Paternalismus, wonach Menschen in ihrer Entscheidungsfindung systematisch fehlschlagen. Die Auswirkungen der zugrundeliegenden psychologischen Forschung werden missinterpretiert und damit vielen menschlichen Entscheidungen eine Art Defekt zugeschrieben. Der zweite Teil des Beitrags hinterfragt die Therapie des libertären Paternalismus. Für entsprechende Interventionen in die Wahlarchitektonik muss Wissen erlangt werden über die Richtung, in welche die Menschen jeweils geschubst werden sollten. Die hier genannte epistemische Aufgabe kann mit den theoretischen Mitteln des libertären Paternalismus nicht gelöst werden.

    Full Text Available Leaves of Echinodorus macrophyllus (Kunth Micheli, Alismataceae, were exposed to different doses of γ-radiation (0.00, 1.00, 3.00, 5.00, 10.00, and 20.00 kGy and the chemical composition of their essential oils was investigated. The extractive process of the essential oil was more favored when the leaves were irradiated. The essential oil components were identified by correlation between GC-FID data and retention parameters obtained from the Kováts method. Moreover, GC-MS analyses of the essential oils were correlated with fragmentation profiles in the NIST standard mass fragmentation data bank. The essential oil of E. macrophyllus contains biologically active constituents of different chemical classes. Acyclic monoterpenes and sesquiterpenes showed increase in concentration when the leaves were exposed to γ-radiation. On the other hand, the component concentrations of some chemical classes were lightly decreased, i.e., for bicyclic monoterpenes, diterpenes, triterpenes, carboxylic esters, and carotenoid derivatives.

    To test a quality improvement intervention, a learning collaborative based on the Institute for Healthcare Improvement's Breakthrough Series methodology, specifically intended to improve care and outcomes for patients with childhood asthma. Randomized trial in primary care practices. Practices in greater Boston, Mass, and greater Detroit, Mich. Forty-three practices, with 13 878 pediatric patients with asthma, randomized to intervention and control groups. Intervention Participation in a learning collaborative project based on the Breakthrough Series methodology of continuous quality improvement. Change from baseline in the proportion of children with persistent asthma who received appropriate medication therapy for asthma, and in the proportion of children whose parent received a written management plan for their child's asthma, as determined by telephone interviews with parents of 631 children. After adjusting for state, practice size, child age, sex, and within-practice clustering, no overall effect of the intervention was found. This methodologically rigorous assessment of a widely used quality improvement technique did not demonstrate a significant effect on processes or outcomes of care for children with asthma. Potential deficiencies in program implementation, project duration, sample selection, and data sources preclude making the general inference that this type of improvement program is ineffective. Additional rigorous studies should be undertaken under more optimal settings to assess the efficacy of this method for improving care.

    Sewage sludge combustion - either in an incinerator or for heat or power generation - has always been important and is getting ever more so. From the cost aspect, it makes quite a difference whether sewage sludge is just incinerated or utilised. The author makes it clear that this cost aspect - and what it means to communities and citizens - tends to be neglected by those who favour sewage sludge combustion and utilisation. [German] Die Verbrennung von Klaerschlamm - sei es als Schlammveraschung oder als thermische oder energetische Verwertung - hat schon immer fuer grosse Klaeranlagen einen bedeutenden Stellenwert gehabt. Die Bedeutung der Verbrennung scheint in letzter Zeit sogar zuzunehmen. Unter Kostengesichtspunkten ist es ein grosser Unterschied, ob ein Klaerschlamm nur verascht oder energetisch verwertet wird. Vor dem Hintergrund der allgemeinen Diskussion um die leeren Kassen der Kommunen, um die sogenannte dritte Miete fuer den Buerger und damit die Zumutbarkeit fuer weitere Steigerungen der Abwassergebuehren stoert mich die Bagatellisierung der Kostengesichtspunkte vor allem auf Seiten derer, die die Verbrennung der Klaerschlaemme fordern.

  9. Effects of a controlled under-ice oil spill on invertebrates of an arctic and a subarctic stream

    Energy Technology Data Exchange (ETDEWEB)

    Miller, M.C.; Stout, J.R.; Alexander, V.

    1986-01-01

    The short-term drift of macroinvertebrates is documented following two controlled oil spills placed under ice in an arctic (Imnavait Creek) and subarctic (Poker-Caribou Creek) stream just as ice covered the water in early winter. No mortality was observed, but several species responded by differentially drifting from the oil-impacted areas during the following days. In the arctic stream, Trichotanypus posticalis (Diptera) showed a significant increase in drift for the first few days. There was also an overall increase in drift of total organisms post spill. Phaenospectra sp. 1, the numerical dominant, decreased its nocturnal drifting compared with the upstream control station in the 5 days post spill. In the subarctic stream, Skwala sp. 1 (Plecoptera), Prosimulium sp. 1 (Simulidae) and Pseudodiamesa sp. 1 showed significant increase din drift post spill. Among the species of benthic invertebrates sampled with a Hess sampler (WILDCO, Saginaw, Mich.), only the density of Nemoura sp. 1 declined significantly post spill. Polar ordinations using percent difference showed that the oil-treated stations separated from the control stations in both the drift and the Hess bottom samples. Colonization of artificial substrates in Imnavait Creek during the winter following the spill was almost non-existent. In Poker-Caribou Creek much colonization took place over the winter with significantly more occurring on unoiled rocks as compared with oiled rocks.

    2016-04-01

    Full Text Available In diesem Beitrag konzentriere ich mich auf die Vorteile einer konsequent durchgeführten interpretativen oder rekonstruktiven Sozialforschung gegenüber anderen qualitativen Verfahren und verdeutliche, inwiefern wir diese Vorteile noch konsequenter verfolgen können als bisher. Dabei stellen sich die folgenden Fragen: Was können wir mit wenigen, aber aufwendigen Fallrekonstruktionen mit dem Ziel einer "theoretischen Verallgemeinerung" am Einzelfall im Unterschied zu qualitativen Verfahren mit umfangreichen Stichproben leisten, die eher eine numerische oder quantitative Verallgemeinerung zum Ziel haben? Inwiefern kommen wir damit überhaupt zu "allgemeinen" Aussagen über die soziale (kollektive und individuelle Wirklichkeit, über eine bestimmte Gruppierung, Organisation oder Ortsgemeinde, einen kollektiver Konflikt, ein bestimmtes Milieu oder soziales Netzwerk? Bei der Behandlung dieser Fragen geht es mir vor allem um ein Plädoyer für eine methodisch stärker historisch und prozess-soziologisch orientierte interpretative Sozialforschung. M.E. liegen in einer konsequenten Rekonstruktion der Verläufe und Wandlungsprozesse von einzelnen "Fällen" und ihrer Verflechtungen mit anderen "Fällen" die Chancen für eine wirklich empirisch geerdete Theorieentwicklung.

    2015-03-01

    Full Text Available Für gewöhnlich wird Heterogenität der Gruppen als Hindernis für Solidarität ihrer Mitglieder angesehen: Je verschiedener die Mitglieder, umso schwieriger kommt Solidarität zustande. In der vorliegenden Studie hinterfrage ich diese Generalisierung, indem ich eine Reihe von theoretischen Ansätzen aus der Soziologie und der Gruppenpsychologie konsultiere. Während einige dieser Ansätze nahelegen, dass Heterogenität der Mitglieder die Solidarität der Gruppen untergräbt, bestreiten dies andere Ansätze und gehen davon aus, dass auch heterogene Gruppen solidarisch sein können, vor allem dann, wenn unter den Mitgliedern eine Interdependenz vorliegt. Diese widersprüchlichen theoretischen Annahmen animierten mich zu einer empirischen Untersuchung von Studierendengruppen in einer Lehrveranstaltung. Die Ergebnisse zeigen zwar, dass zwischen Heterogenität und Solidarität in den interdependenten Gruppen ein Zusammenhang anzunehmen ist, dass jedoch auch eine Ambivalenz besteht zwischen individueller und Kollegensolidarität. Vor dem Hintergrund der theoretischen und empirischen Erkenntnisse diskutiere ich Schlussfolgerungen für die Forschung und für die praktischen Bemühungen der Solidarisierung im Bereich der gewerkschaftlichen Organisierung.

    Full Text Available [Dieser Artikel ist Teil einer Debatte] Der Text „Thesen zur Soziologie der Stadt“ scheint mir besonders in den abschließend formulierten Perspektiven, die Hartmut Häußermann und Walter Siebel unter der Überschrift „Aufgaben einer kritischen Soziologie der Stadt“ formulieren, nach wie vor lesenswert und aktuell zu sein. Drei Perspektiven werden hier aufgezeigt: erstens eine Wissenschafts- und Ideologiekritik, zweitens eine empirisch orientierte Zustandsbeschreibung städtischer Strukturen und von Stadtentwicklung sowie drittens eine Analyse der staatlichen Stadtpolitik. Diese drei abschließenden Perspektiven möchte ich im Folgenden kommentieren. Es wird mithin keine immanente Auseinandersetzung mit dem gesamten Text und weiteren Arbeiten der beiden Autoren angestrebt. Es hätte mich zwar durchaus gereizt, die Entwicklung der Arbeiten von Häußermann und Siebel vor dem Hintergrund dieses frühen, emphatisch formulierten Textes zu reflektieren. Vielleicht auch wegen der persönlichen Bekanntschaft mit Häußermann, den ich als Projekt- und Dissertationsbetreuer an der Humboldt-Universität kennenlernte, erschien mir eine solche Zugangsweise zu den „Thesen“ durchaus naheliegend.

    Full Text Available Da die menschliche Sexualität nicht natürlich ist, reichen anatomische oder biologische Argumente nicht, um sie aufzuklären. Freud entdeckte, dass der Geschlechtsunterschied durch den Signifikanten vermittelt wird, denn Triebe als solche ignorieren die Dichotomie Mann/Frau. Jacques Lacan greift diesen vernachlässigten Aspekt auf und hebt die Schicksale des Subjekts mit der Sprache durch seine Lehre als etwas Fundamentales hervor. In Anbetracht der Prämisse, dass «die Neurose wie eine Frage strukturiert» sei, drücken die komplexen symptomatischen Manifestationen der Hysterika ihren Versuch aus, sich in einen Diskurs einzuschreiben, der von der Unmöglichkeit, eine kategoriale Antwort auf das Rätsel der Weiblichkeit zu geben, geprägt ist. Deren Frage lautet also: Was ist eine Frau? Ein Signifikant ergibt nur Sinn in Verbindung zu einem anderen Signifikanten und daher werden wir alle den durch den Signifikanten vermittelten Sachen gegenüber unabänderlich entfremdet. Aus dieser Sichtweise heraus möchte ich mich mit der Frage der Heterosexualität auseinandersetzen.

    Full Text Available Corporate websites are essential platforms through which firms introduce their goods and services on B2B and B2C level, express financial information for the stakeholders and share corporate values, purposes and activities. Due to its facilities, websites take part in firm positioning strategy. Accordingly this study aims to understand the innovation oriented positioning through corporate websites. The method applied in this study has been adapted from the 2QCV2Q Model developed by Mich and Franch (2000 to evaluate websites and top 30 firms with the highest Research and Development expenditures listed in Turkishtime (2015 have been analyzed. Within this context, this study presents a revised and updated method for the assessments of websites through positioning strategy framework. Findings indicate no direct relationship between website evaluation and R&D expenditure, though some common weaknesses have been put forward, such as information about management of the firms. Besides, publicly traded firms are recognized to facilitate websites more efficiently than non-publicly traded firms. Study contribute to both academia and practitioners as putting forward a new approach for 2QCV2Q Model and indicating the similarities and differences among the corporate websites through positioning perspective.

  15. Determining customer satisfaction in anatomic pathology.

    Science.gov (United States)

    Zarbo, Richard J

    2006-05-01

    Measurement of physicians' and patients' satisfaction with laboratory services has become a standard practice in the United States, prompted by national accreditation requirements. Unlike other surveys of hospital-, outpatient care-, or physician-related activities, no ongoing, comprehensive customer satisfaction survey of anatomic pathology services is available for subscription that would allow continual benchmarking against peer laboratories. Pathologists, therefore, must often design their own local assessment tools to determine physician satisfaction in anatomic pathology. To describe satisfaction survey design that would elicit specific information from physician customers about key elements of anatomic pathology services. The author shares his experience in biannually assessing customer satisfaction in anatomic pathology with survey tools designed at the Henry Ford Hospital, Detroit, Mich. Benchmarks for physician satisfaction, opportunities for improvement, and characteristics that correlated with a high level of physician satisfaction were identified nationally from a standardized survey tool used by 94 laboratories in the 2001 College of American Pathologists Q-Probes quality improvement program. In general, physicians are most satisfied with professional diagnostic services and least satisfied with pathology services related to poor communication. A well-designed and conducted customer satisfaction survey is an opportunity for pathologists to periodically educate physician customers about services offered, manage unrealistic expectations, and understand the evolving needs of the physician customer. Armed with current information from physician customers, the pathologist is better able to strategically plan for resources that facilitate performance improvements in anatomic pathology laboratory services that align with evolving clinical needs in health care delivery.

    1992-06-01

    Full Text Available Luther’s translation of Psalm 22:22 reads: "Deliver me from the unicorns" (errette mich von den Einhömem. This translation arouses curiosity for it is common knowledge that the unicorn has never existed but yet figures as a prominent symbol of the New Age. Besides, the Hebrew word means antelope, buffalo, or wild bull. The question thus arises why the Hebrew re'em was translated by Luther with unicorn While the official Dutch translation of 1633 (Statenvertaling, translated according to the title page from the original languages gives the same translation as Luther, the obvious deduction was that the unicorn was such a powerful symbol in 16th century Europe that it slipped into the Bible translations. However, Calvin, tending even less than Luther to allegory and non-literal interpretation, also mentions the unicorns in his commentary on Psalm 22:22. This renders Jerome’s Vulgate suspect and, indeed, the Vulgate translates the Hebrew word with unicorns. The next stop was the translation of the Septuagint, which reads monokeros. In this way the cultural background as a possible explanation of this translation shifted from the 16th century to the first centuries B.C.

    The source of radioactive contamination of the Yenisei River floodplain, including contamination with transuranic elements, is the Mining-and-Chemical Combine of the Russian Ministry of Atomic Energy, which has for many years been producing weapons-grade plutonium. Transuranic elements have been detected not only in the soil and sediment of the river but also in the biomass of aquatic plants. This work is an investigation of accumulation and release of 241Am by a submerged macrophyte of the Yenisei River (Elodea canadensis) in laboratory experiments. In 2000-2003, laboratory experiments were carried out with biomass of E. canadensis Mich. and filtered river water. The samples were collected from the Yenisei River upstream of the discharge of the Combine's radioactive effluent. The experiments showed that 241Am is accumulated by Elodea biomass: the activity concentration of 241Am can reach 3280+/-240 Bq/g, with the concentration factor for 241Am 16 600+/-2200l/kg. Results of chemical fractionation have proved that in the course of 241Am accumulation by Elodea biomass, 241Am tightly bound to biomass increases from 11% to 27% of the total 241Am in the biomass. Release of 241Am from the decaying Elodea biomass has been evaluated experimentally. By the end of the experiment (lasting up to 127 days), the Elodea plants had lost up to 65% of their initial 241Am activity and the rate of 241Am release into the water environment reached 23 Bq/day.

Results of chemical fractionation have proved that in the course of 241 Am accumulation by Elodea biomass, 241 Am tightly bound to biomass increases from 11% to 27% of the total 241 Am in the biomass. Release of 241 Am from the decaying Elodea biomass has been evaluated experimentally. By the end of the experiment (lasting up to 127 days), the Elodea plants had lost up to 65% of their initial 241 Am activity and the rate of 241 Am release into the water environment reached 23 Bq/day

Autism spectrum disorder (ASD refers to a group of individuals with impairments in aspects of communication and a particular pattern of language acquisition. Although ASD and WS are polar opposites when it comes to communication abilities (language and emotion and social behavior, comparisons between WS and ASD are still rare in the literature. ASD and WS are both associated with general language and developmental delays. Difficulties in social interaction and general pragmatic difficulties are reported in both ASD and WS, but are more pervasive in ASD. Regarding facial emotion recognition, the two syndromes differ markedly in sensitivity to human faces. Despite the heterogeneity of these two groups, only a few studies with children have paid sufficient attention to participant recruitment and study design. A number of aspects need to be taken into account (eg, small age range, homogeneity of the subgroups, matching with typically developing children if scientific results are to inform the design of intervention programs for children with neurodevelopmental disorders such as ASD and WS.

    The RADIOM model, [1-2], allows one to implement non-LTE atomic physics with a very low extra CPU cost. Although originally heuristic, RADIOM has been physically justified [3] and some accounting for auto-ionization has been included [2]. RADIOM defines an ionization temperature Tz derived from electronic density and actual electronic temperature Te. LTE databases are then queried for properties at Tz and NLTE values are derived from them. Some hydro-codes (like FAST at NRL, Ramis' MULTI, or the CRASH code at U.Mich) use inverse EOS starting from the total internal energy Etot and returning the temperature. In the NLTE case, inverse EOS requires to solve implicit relations between Te, Tz, and Etot. We shall describe these relations and an efficient solver successively implemented in some of our codes.

    Full Text Available In recent years, the iris recognition system has been gaining increasing acceptance for applications such as access control and smartphone security. When the images of the iris are obtained under unconstrained conditions, an issue of undermined quality is caused by optical and motion blur, off-angle view (the user’s eyes looking somewhere else, not into the front of the camera, specular reflection (SR and other factors. Such noisy iris images increase intra-individual variations and, as a result, reduce the accuracy of iris recognition. A typical iris recognition system requires a near-infrared (NIR illuminator along with an NIR camera, which are larger and more expensive than fingerprint recognition equipment. Hence, many studies have proposed methods of using iris images captured by a visible light camera without the need for an additional illuminator. In this research, we propose a new recognition method for noisy iris and ocular images by using one iris and two periocular regions, based on three convolutional neural networks (CNNs. Experiments were conducted by using the noisy iris challenge evaluation-part II (NICE.II training dataset (selected from the university of Beira iris (UBIRIS.v2 database, mobile iris challenge evaluation (MICHE database, and institute of automation of Chinese academy of sciences (CASIA-Iris-Distance database. As a result, the method proposed by this study outperformed previous methods.

    Full Text Available Was heißt es, sich in unserer globalisierten Welt als eine vollverantwortliche Person zu verstehen und zu verhalten? Einerseits scheint es richtig, dass wir global verantwortlich sind, d.h. dass wir auch gegen entferntes Leid etwas tun sollten; andererseits aber ist wegen vielfacher Überforderungsproblemen unklar ist, wie man diese Verantwortung tatsächlich übernehmen können soll – was wiederum dagegen spricht, dass wir diese Verantwortung berechtigtermaßen zuschreiben können. Um einen Aspekt dieses großen Themas zu behandeln, konzentriere ich mich in diesem Aufsatz auf den Anwendungsbereich von extremer Armut und argumentiere in folgenden Schritten. Zuerst spitze ich das Thema zu auf ein Problem, das Samuel Scheffler in diesem Zusammenhang konstatiert hat, nämlich einen Widerstreit zwischen dem, was Verantwortung unter den Bedingungen der Globalisierung bedeutet und dem, wie wir uns grundsätzlich als Handelnde zu verstehen gewohnt sind. Dann zeige ich erstens, dass dem Thema einer epistemischen Überforderung dabei entscheidendes Gewicht zugesprochen wird, zweitens jedoch, dass sich, genauer besehen, dieses Problem gar nicht in dieser Art stellt. Dafür schlage ich eine Analyse des Verantwortungsbegriffs vor, die es ermöglicht, Kriterien zu identifizieren, anhand derer gewisse Grenzen gezogen werden können, so dass die Zuschreibung der Verantwortung gerechtfertigt werden kann.

    Full Text Available Der vorliegende Beitrag beschäftigt sich mit der Frage, wie sich eine aus spontaner Mobilisierung entstandene soziale Bewegung als kollektive Formation im Internet entwickelt. Da spontane Bewegungen in aller Regel nur über eine schwache kollektive Identität verfügen, werden sie bislang überwiegend als Übergangsphänomen betrachtet. Viele Studien beschäftigten sich eher mit den Folgen spontaner Mobilisierung, insbesondere der Frage, wie daraus eine nachhaltige Bewegung entstehen kann. Die kollektive Formation selbst ist bis dato weitgehend eine Blackbox geblieben. In der vorliegenden Studie widme ich mich folgenden zentralen Forschungsfragen: 1. Wie werden kollektive Formationen aus spontanen ProtestteilnehmerInnen dargestellt und generiert? 2. Wie ändern sich diese im Verlauf der Mobilisierung? Im Mittelpunkt der empirischen Analyse stehen Online-Kommentare, die eine zunehmend wichtige Rolle für soziale Bewegungen und spontane Mobilisierungsprozesse spielen. Am Beispiel von PEGIDA wird die Konstruktion einer kollektiven Formation über Live-Kommentare zu Live-Übertragungen von PEGIDA-Demonstrationen sowie deren Wandel in drei Phasen untersucht. Im ersten Schritt werden die soziotechnischen Grundlagen kollektiven Handelns im Internet erläutert. Der zweite Schritt befasst sich mit der methodischen Vorgehensweise. Im dritten Schritt werden ausgewählte Textpassagen von Online-Kommentaren analysiert. Anschließend wird der Wandel kollektiver Formationen nachgezeichnet.

  7. Deep Learning-Based Iris Segmentation for Iris Recognition in Visible Light Environment

    Directory of Open Access Journals (Sweden)

    2017-11-01

    Full Text Available Existing iris recognition systems are heavily dependent on specific conditions, such as the distance of image acquisition and the stop-and-stare environment, which require significant user cooperation. In environments where user cooperation is not guaranteed, prevailing segmentation schemes of the iris region are confronted with many problems, such as heavy occlusion of eyelashes, invalid off-axis rotations, motion blurs, and non-regular reflections in the eye area. In addition, iris recognition based on visible light environment has been investigated to avoid the use of additional near-infrared (NIR light camera and NIR illuminator, which increased the difficulty of segmenting the iris region accurately owing to the environmental noise of visible light. To address these issues; this study proposes a two-stage iris segmentation scheme based on convolutional neural network (CNN; which is capable of accurate iris segmentation in severely noisy environments of iris recognition by visible light camera sensor. In the experiment; the noisy iris challenge evaluation part-II (NICE-II training database (selected from the UBIRIS.v2 database and mobile iris challenge evaluation (MICHE dataset were used. Experimental results showed that our method outperformed the existing segmentation methods.

    The optimal fermentation temperature, pH, and Bacto-casitone (Difco Laboratories, Detroit, Mich.) concentration for production of exopolysaccharide by Lactobacillus delbrueckii subsp. bulgaricus RR in a semidefined medium were determined by using response surface methods. The design consisted of 20 experiments, 15 unique combinations, and five replications. All fermentations were conducted in a fermentor with a 2.5-liter working volume and were terminated when 90% of the glucose in the medium had been consumed. The population of L. delbrueckii subsp. bulgaricus RR and exopolysaccharide content were measured at the end of each fermentation. The optimum temperature, pH, and Bacto-casitone concentration for exopolysaccharide production were 38°C, 5, and 30 g/liter, respectively, with a predicted yield of 295 mg of exopolysaccharide/liter. The actual yield under these conditions was 354 mg of exopolysaccharide/liter, which was within the 95% confidence interval (217 to 374 mg of exopolysaccharide/liter). An additional experiment conducted under optimum conditions showed that exopolysaccharide production was growth associated, with a specific production at the endpoint of 101.4 mg/g of dry cells. Finally, to obtain material for further characterization, a 100-liter fermentation was conducted under optimum conditions. Twenty-nine grams of exopolysaccharide was isolated from centrifuged, ultrafiltered fermentation broth by ethanol precipitation. PMID:9464404

    Community health centers have evolved from fringe providers to mainstays of many local health care systems. Those designated as federally qualified health centers (FQHCs), in particular, have largely established themselves as key providers of comprehensive, efficient, high-quality primary care services to low-income people, especially Medicaid and uninsured patients. The Center for Studying Health System Change's (HSC's) site visits to 12 nationally representative metropolitan communities since 1996 document substantial growth in FQHC capacity, based on growing numbers of Medicaid enrollees and uninsured people, increased federal support, and improved managerial acumen. At the same time, FQHC development has varied considerably across communities because of several important factors, including local health system characteristics and financial and political support at federal, state and local levels. Some communities--Boston; Syracuse, N.Y.; Miami; and Seattle--have relatively extensive FQHC capacity for their Medicaid and uninsured populations, while other communities--Lansing, Mich.; northern New Jersey; Indianapolis; and Greenville, S.C.--fall in the middle. FQHC growth in Phoenix; Little Rock, Ark.; Cleveland; and Orange County, Calif.; has lagged in comparison. Today, FQHCs seem poised to play a key role in federal health care reform, including coverage expansions and the emphasis on primary care and medical homes.

El objetivo del presente estudio es valorar los efectos adversos asociados a la vacunación antigripal en niños. MÉTODOS: estudio prospectivo realizado en las campañas 92/93, 93/94 y 97/98 en 105 niños de Navalcarnero, con vacuna antigripal de virus fraccionados e inactivados con las cepas vacunales recomendadas por la OMS. Todas las dosis son administradas por una enfermera, que también realiza los controles postvacunales a las 72 horas. Se valoran los efectos adversos, la zona de inyección, el sexo, la edad, la vacunación previa y el recoger los datos por teléfono o en consulta. RESULTADOS: de forma global, en 318 dosis administradas, a nivel local aparece reacción en el 10,7%, en forma de eritema (8,5%, induración (7,9% y dolor (sólo 97/98, 13,9% y a nivel sistémico en el 11,9%, en forma de rinorrea (3,1%, malestar general (2,5%, fiebre (2,5%, dolores musculares (1,6% y tos (1,6%. El 89,5% de los efectos sistémicos desaparecen en las primeras 48 horas. Ningún caso precisó consulta médica. CONCLUSIONES: la vacuna es segura. Los efectos adversos que aparecen son escasos, leves y bien tolerados. No existen diferencias significativas en función de la edad, el sexo, la vacunación previa o el hecho de recoger los resultados por teléfono o en consulta.

La riqueza de palmas encontrada en las localidades estudiadas (29 especies en 1.5 ha y 23 especies en 1 ha, está entre las más altas registradas para el Neotrópico, y corrobora el patrón de distribución de riqueza ligado a altas precipitaciones. La mayoría de las especies están representadas por pocos individuos, mientras que unas pocas son las más abundantes y frecuentes. Se identificó un grupo de especies (Wettinia quinaria, Welfia regia, Iriartea deltoidea, Socratea exorrhiza, Oenocarpus bataua, en el dosel, y Geonoma cuneata, en el sotobosque, que son particularmente importantes a nivel ecológico, y que caracterizan y modelan la vegetación, no sólo del área de estudio, sino también, al parecer, a lo largo de la región del Chocó Biogeográfico. Con base en los resultados y en otros datos florísticos, se plantea que, si bien las palmas son importantes a todo lo largo de la región, la mayor abundancia y riqueza parece presentarse hacia la zona central, que coincide con un aumento en el gradiente de precipitación. Veintisiete de las 33 especies encontradas tenía algún uso en una de las siete categorías de uso, lo cual muestra la importancia de las palmas para las poblaciones locales.

    Full Text Available Gli Squallor: La risata triste e le pernacchieLa satira sociale e politica nella musica italiana durante la Prima RepubblicaAnche se spesso viene catalogato con il marchio onnicomprensivo di ‘Rock demenziale’, il gruppo musicale italiano degli Squallor rappresenta uno dei fenomeni più incisivi di satira politica e sociale nell’Italia moderna. Ciò appare evidente se si esaminano i numerosi pezzi contenuti nei loro album, che presentano brillanti e corrosive parodie di noti partiti e politici, nonché di tendenze culturali e sociali dominanti. Se consideriamo inoltre il periodo in cui gli Squallor raggiunsero il massimo successo (verso la metà degli anni Ottanta, essi possono anche rappresentare l’importante voce di dissenso che caratterizzò gli ultimi decenni della cosiddetta Prima Repubblica. In questo articolo viene esplorata una selezione dei loro più importanti testi, con lo scopo di analizzare le dinamiche della loro particolarissima satira in relazione alle tendenze culturali, sociali e politiche allora in voga in Italia.

    To evaluate regional cerebral metabolic and structural changes in patients with minimal hepatic encephalopathy (MHE) using two-dimensional (2D) MR spectroscopy (MRS) and T( (1) )-weighted MRI, to correlate the observed MR changes with neuropsychological (NP) test scores, and to compare the diagnostic accuracy of MRI, 2D MRS, and NP tests in discriminating between patients and healthy subjects. Thirty-three MHE patients and 30 healthy controls were investigated. The 2D localized correlated spectroscopy (L-COSY) was performed in the frontal and occipital brain on a 1.5 Tesla (T) MR scanner. The NP test battery included 15 tests, grouped into 6 cognitive domains. Globus pallidus signal intensities were calculated from T(1)-weighted images. The 2D MRS showed significant differences in ratios of the following metabolite(s) peaks with respect to creatine (Cr): decreased myo-inositol (mI), choline (Ch), mICh, and increased (glutamate plus glutamine) (Glx) in patients compared with healthy subjects in both occipital and frontal lobes. Frontal lobe taurine also showed a decline in patients. The NP test results revealed declines in cognitive speed, motor function, executive function, and global cognitive status. Significant correlations were found between the altered metabolites and NP tests. Alteration in the mICh/Cr ratio was noted as a powerful discriminant between healthy subjects and the patients. The study demonstrates that relative metabolite levels determined by 2D MRS, in particular mICh/Cr, provide the best diagnostic prediction for MHE. The results suggest that depletions of myo-inositol, choline and taurine with respect to creatine correlate with measures of neuropsychological impairment. (c) 2010 Wiley-Liss, Inc.

    Full Text Available Freshwater crabs are important elements in the aquatic biota of brooks, rivers, lakes and ponds, from both ecological and the socio-economic aspects. Trichodactylidae comprises 51 endemic species from the Neotropical region. Among all the species of this family, Trichodactylus fluviatilis Latreille, 1828 has the widest geographic distribution throughout Brazil. Despite that, there are few published contributions on the biology of this species. The present study investigated the following aspects of T. fluviatilis: relative growth, mean size at onset of morphometric maturity, sexual dimorphism, laterality and heterochely. Specimens were collected monthly from September 2010 through August 2011, from the Velha Eugênia Brook, municipality of Santa Teresinha, State of Bahia. Carapace width (CW, carapace length (CL, major cheliped length (MaCL and minor cheliped length (MiCL, major cheliped height (MaCH and minor cheliped height (MiCH, and width of the fifth abdominal segment (5AB were measured to evaluate the presence of sexual dimorphism; the major difference between the sexes was in the CW vs. 5AB ratio. Heterochely was observed in males and females,with the right cheliped larger than the left in 89% of males and 81% of females. Crab size at the onset of morphometric maturity (= puberty molt was estimated based on the ratio between CL, cheliped dimensions, 5AB and CW (independent variable. Females were larger than males when they reached morphometric maturity in all studied relations. We recommend the use of chelipeds and abdominal width relationships to estimate the size at the morphometric maturity in males and females, respectively.

    In the present elaboration of four speeches, which I have held at the Princeton University in May 1921 I wanted to summarize the main thoughts and mathematical methods of relativity theory. Thereby I have attempted to leave out all less essential but to treat the fundamental so that the whole can serve as introduction for all those which master the elements of advanced mathematics but want not apply all to much time and inconvenience to the object. Completeness can this short presentation self-evidently not require so much as I have not treated the more subtle, more mathematically interesting developments, which are based on the variational calculus. My main goal was to let the fundamental in the whole way of thought of the theory clearly come forward. [German] ''In der vorliegenden Ausarbeitung von vier Vortraegen, die ich an der Universitaet Princeton im Mai 1921 gehalten habe, wollte ich die Hauptgedanken und mathematischen Methoden der Relativitaetstheorie zusammenfassen. Dabei habe ich mich bemueht, alles weniger Wesentliche wegzulassen, das Grundsaetzliche aber doch so zu behandeln, dass das Ganze als Einfuehrung fuer alle diejenigen dienen kann, welche die Elemente der hoeheren Mathematik beherrschen, aber nicht allzuviel Zeit und Muehe auf den Gegenstand verwenden wollen. Auf Vollstaendigkeit kann diese kurze Darlegung selbstverstaendlich keinen Anspruch machen, zumal ich die feineren, mehr mathematisch interessanten Entwicklungen, welche sich auf Variationsrechnung gruenden, nicht behandelt habe. Mein Hauptziel war es, das Grundsaetzliche in dem ganzen Gedankengang der Theorie klar hervortreten zu lassen.'' Albert Einstein (Vorwort zur 1.

    Full Text Available No mito de Pandora, quando a caixa é aberta, males são espalhados pelo mundo e somente a esperança permanece. De que esperança o mito nos fala? Pode a Literatura ser considerada um recurso de enfrentamento diante dos males que nos acometem? Pode a Literatura em algumas situações ser a porta-voz da esperança? Este artigo apresentará a definição de mito, suas características e qual seu valor na história da Humanidade. Também apresentará o mito de Pandora e as variações encontradas, além de trazer algumas representações artísticas sobre Pandora e o quanto cada uma delas fala da visão histórica de mulher. Abordará as semelhanças e diferenças entre o mito grego e o mito judaico da criação de Eva, a primeira mulher. O artigo pretende assinalar como o conceito de esperança é variável, dependendo do momento histórico e dos sujeitos sociais e explorar o conceito de resiliência, originário da Física e da Engenharia e tomado emprestado pela Psicologia para estudar os processos de resistência e sobrevivência aos infortúnios e à adversidade. Também discutirá a possibilidade da Literatura servir como instrumento de reconstrução do sujeito, apresentando o trabalho da antropóloga Michèle Petit com grupos em risco social através da leitura compartilhada.

A bakuchiol, Ginkgo biloba extract, and mannitol (BGM complex has been developed to provide patients with acne with a specific dermocosmetic to be used adjunctively with conventional treatments. Objective: The aim of these studies was to assess the antibacterial, anti-inflammatory, and antioxidative potential of BGM complex and its individual compounds as well as its impact on sebum composition. Methods: The antibacterial, anti-inflammatory, and antioxidative potential of BGM complex and its compounds was assessed through in vitro, ex vivo, and clinical studies. The clinical benefit of BGM complex formulated in a cream was assessed in subjects prone to acne through sebum composition analysis and photometric assessments. Results: Results from the studies showed that the BGM complex has significant antibacterial, anti-inflammatory, and antioxidative properties. At similar concentrations, bakuchiol has up to twice the antioxidative potential than vitamin E. In subjects, BGM complex regulated the sebum composition in acne patients by increasing the level of sapienic and linolenic acid and reducing the level of oleic acid. The reduced number of porphyrins on the skin surface showed that it is also effective against P. acnes. Conclusion: BGM complex provides a complete adjunctive care in patients with acne by targeting etiopathogenic factors of acne: dysseborrhea, inflammation, and P. acnes proliferation. Keywords: acne, antibacterial, anti-inflammatory, antioxidation, cosmetics, sebum

    The source of radioactive contamination of the Yenisei River floodplain, including contamination with transuranic elements, is the Mining-and-Chemical Combine of the Russian Ministry of Atomic Energy, which has for many years been producing weapons-grade plutonium. Transuranic elements have been detected not only in the soil and sediment of the river but also in the biomass of aquatic plants. This work is an investigation of accumulation and release of {sup 241}Am by a submerged macrophyte of the Yenisei River (Elodea canadensis) in laboratory experiments. In 2000-2003, laboratory experiments were carried out with biomass of E. canadensis Mich. and filtered river water. The samples were collected from the Yenisei River upstream of the discharge of the Combine's radioactive effluent. The experiments showed that {sup 241}Am is accumulated by Elodea biomass: the activity concentration of {sup 241}Am can reach 3280 {+-} 240 Bq/g, with the concentration factor for {sup 241}Am 16 600 {+-} 2200 l/kg. Results of chemical fractionation have proved that in the course of {sup 241}Am accumulation by Elodea biomass, {sup 241}Am tightly bound to biomass increases from 11% to 27% of the total {sup 241}Am in the biomass. Release of {sup 241}Am from the decaying Elodea biomass has been evaluated experimentally. By the end of the experiment (lasting up to 127 days), the Elodea plants had lost up to 65% of their initial {sup 241}Am activity and the rate of {sup 241}Am release into the water environment reached 23 Bq/day.

In contrast to previous research, we were interested not only in specific pain coping but also in more general stress coping strategies and their potential influence on pain outcomes. Analyses were performed using correlation and regression analyses. “Praying and hoping” turned out to be an independent predictor of higher pain intensity and higher anxiety levels, whereas both “coping self-instructions” and “diverting attention” were associated with higher well-being, less feelings of helplessness, and less depression and anxiety. We further found a link between “focusing on and venting emotions” and “worse pain adjustment”. No significant relationship between dyadic coping and social support with any of our pain outcomes could be observed. Overall, our results indicate that individual coping strategies outweigh the effects of social support and dyadic coping on pain-related outcomes and pain adjustment. However, results need to be interpreted with caution given the small sample size. Keywords: individual coping, dyadic coping, social support, chronic pain

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.

    Full Text Available Abstract Echinodorus scaber Rataj and Echinodorus grandiflorus (Cham. & Schltdl. Micheli, Alismataceae, are popularly used to relieve inflammatory complaints and as diuretic. A study on the antinociceptive effect and selected marker compounds in eleven extracts from different locations was undertaken and their antinociceptive effect was assessed. The fingerprints were compared by HPLC-DAD and the content of vitexin, isovitexin, isoorientin and vitexin-2-O-rhamnoside were determined. All samples presented antinociceptive activity reducing the writhes by 36.4-62.5% and 47.4-79.8% at 10 and 50 mg/kg, respectively; indomethacin (5 mg/kg reduced writhes by 82.6-90.1%. The content of the flavonoids C-glycosides, however, presented a strong variation. Isovitexin and isoorientin were found in all the samples, with content ranging from traces to 14.70 µg/mg and 2.12-84.27 µg/mg extract, respectively, while vitexin-2-O-rhamnoside occurred in quantifiable amounts only in 3 out of 11 samples ranging from 5.43 to 33.13 µg/mg extract; vitexin was not detected at all or detected in trace amounts. According to the fingerprints, the samples could be arranged in four main groups. All eleven extracts showed antinociceptive activity. Isovitexin was the only flavonoid present in all samples and can be regarded, acting in synergy with the other compounds or not, as the responsible for the antinociceptive activity. Therefore, isovitexin is a good choice as chemical marker when the antinociceptive activity of E. scaber and E. grandiflorus is investigated.

Taking as a point of departure works by leading scholars, such as Israel Bartal, Cesare G. De Michelis, Jonathan Frankel, John D. Klier, Dan Miron, Benjamin Nathans, Laura Salmon, Yohanan Petrovsky-Shtern, and Yuri Slezkine, this article aims at offering some new perspectives on the Pale of Settlement and on the history and culture of Russian Jewry during the reign of Alexander II. It highlights the laws and reforms concerning Russian Jews implemented by the Tsar’s government, and their fallout on Russian culture. The Author analyzes Jewish geography, urban space, history, legislation, reforms, society, cultural convergences and differences in the Pale of Settlement. The paper concludes with information about the 1881-1882 Russian pogroms and about how certain Jewish inhabitants of the Pale of Settlement then emigrated towards Central and Western Europe, the Middle East and the Americas. The paper discusses the commonplace of a separate Jewish space in the Pale envisaged in some late 19th and early 20th Century Yiddish literature, and describes the multicultural universe made up of several nationalities, one of which was in fact Russian Jewry, struggling for its rights and for full emancipation.

    Water samples collected from 20 stream sites in Oakland and Macomb Counties, Mich., were analyzed to learn more about the occurrence of cephalosporin-resistant Escherichia coli (E. coli) and vancomycin-resistant enterococci (VRE) and the co-occurrence of antibiotics and mercury in area streams. Fecal indicator bacteria concentrations exceeded the Michigan recreational water-quality standard of 300 E. coli colony forming units (CFU) per 100 milliliters of water in 19 of 35 stream-water samples collected in Oakland County. A gene commonly associated with enterococci from humans was detected in samples from Paint Creek at Rochester and Evans Ditch at Southfield, indicating that human fecal waste is a possible source of fecal contamination at these sites. E. coli resistant to the cephalosporin antibiotics (cefoxitin and/ or ceftriaxone) were found at all sites on at least one occasion. The highest percentages of E. coli isolates resistant to cefoxitin and ceftriaxone were 71 percent (Clinton River at Auburn Hills) and 19 percent (Sashabaw Creek near Drayton Plains), respectively. Cephalosporin-resistant E. coli was detected more frequently in samples from intensively urbanized or industrialized areas than in samples from less urbanized areas. VRE were not detected in any sample collected in this study. Multiple antibiotics (azithromycin, erythromycin, ofloxacin, sulfamethoxazole, and trimethoprim) were detected in water samples from the Clinton River at Auburn Hills, and tylosin (an antibiotic used in veterinary medicine and livestock production that belongs to the macrolide group, along with erythromycin) was detected in one water sample from Paint Creek at Rochester. Concentrations of total mercury were as high as 19.8 nanograms per liter (Evans Ditch at Southfield). There was no relation among percentage of antibiotic-resistant bacteria and measured concentrations of antibiotics or mercury in the water. Genetic elements capable of exchanging multiple antibiotic

    Cordia ecalyculata Vell. and Echinodorus grandiflorus (Cham. & Schltdl.) Micheli are extensively used in Brazil as therapeutic preparations for indigenous groups and the general population. These plants have been used in the folk medicine as: tonic, diuretic, anti-inflammatory, appetite suppressants, for the treatment of snake bites, and weight loss. In this study, it was verified the possible cytotoxic and genotoxic effects of the crude extracts of. Cordia ecalyculata and Echinodorus grandiflorus, as well as their effectiveness in treating obesity. The Micronucleus Test was used for the evaluation of possible clastogenic and aneugenic effects, and the Comet Assay was used for the evaluation of single-strand and double-strand DNA breaks. The cytotoxic effects of the crude extracts were verified by PCE/NCE ratio. Swiss mice (Mus musculus) were used as the experimental model. It was observed a significant (PCordia ecalyculata or Echinodorus grandiflorus extracts, in comparison with the negative control. There were no significant differences (P>0.05) in the frequency of micronucleated polychromatic erythrocytes for both extract treatment. We observed that treatment with the Cordia ecalyculata extract at concentrations of 1000 and 2000 mg/kg bw resulted in a PCE/NCE ratio that was larger (P0.05). The results of this study allowed us to infer that the crude extracts of Cordia ecalyculata and Echinodorus grandiflorus do not display cytotoxic or genotoxic activities. However, they do possess weak clastogenic activity (without significance) on peripheral blood cells. Contrary to commonly held beliefs it was also found in this study that the extracts are not effective for obesity treatments. Copyright 2009 Elsevier Ireland Ltd. All rights reserved.

The different techniques available for analyzing biometric and morphological items of the profile, eyes, ears, lips, and hard and soft palate are commented on and briefly compared with the respective bi-dimensional techniques. The available literature supports the use of three-dimensional ultrasound in difficult prenatal diagnostic conditions because of its diagnostic accuracy, enabling improved safety of perinatal care. Globally, a marked increase has been observed in the accuracy of three-dimensional ultrasound in comparison with the bi-dimensional approach. Because there is no consensus about the performance of the different three-dimensional techniques, future studies are needed in order to compare them and to find the best technique for analysis of each of the respective facial elements. Universal prenatal standards may integrate these potential new findings in the future. At this time, the existing guidelines for prenatal facial screening should not be changed.Keywords: prenatal three-dimensional ultrasound, prenatal screening, prenatal diagnosis, cleft lip and palate, fetal profile, retrognathism

    The recent advancements in computer vision have opened new horizons for deploying biometric recognition algorithms in mobile and handheld devices. Similarly, iris recognition is now much needed in unconstraint scenarios with accuracy. These environments make the acquired iris image exhibit occlusion, low resolution, blur, unusual glint, ghost effect, and off-angles. The prevailing segmentation algorithms cannot cope with these constraints. In addition, owing to the unavailability of near-infrared (NIR) light, iris recognition in visible light environment makes the iris segmentation challenging with the noise of visible light. Deep learning with convolutional neural networks (CNN) has brought a considerable breakthrough in various applications. To address the iris segmentation issues in challenging situations by visible light and near-infrared light camera sensors, this paper proposes a densely connected fully convolutional network (IrisDenseNet), which can determine the true iris boundary even with inferior-quality images by using better information gradient flow between the dense blocks. In the experiments conducted, five datasets of visible light and NIR environments were used. For visible light environment, noisy iris challenge evaluation part-II (NICE-II selected from UBIRIS.v2 database) and mobile iris challenge evaluation (MICHE-I) datasets were used. For NIR environment, the institute of automation, Chinese academy of sciences (CASIA) v4.0 interval, CASIA v4.0 distance, and IIT Delhi v1.0 iris datasets were used. Experimental results showed the optimal segmentation of the proposed IrisDenseNet and its excellent performance over existing algorithms for all five datasets.

In addition, owing to the unavailability of near-infrared (NIR light, iris recognition in visible light environment makes the iris segmentation challenging with the noise of visible light. Deep learning with convolutional neural networks (CNN has brought a considerable breakthrough in various applications. To address the iris segmentation issues in challenging situations by visible light and near-infrared light camera sensors, this paper proposes a densely connected fully convolutional network (IrisDenseNet, which can determine the true iris boundary even with inferior-quality images by using better information gradient flow between the dense blocks. In the experiments conducted, five datasets of visible light and NIR environments were used. For visible light environment, noisy iris challenge evaluation part-II (NICE-II selected from UBIRIS.v2 database and mobile iris challenge evaluation (MICHE-I datasets were used. For NIR environment, the institute of automation, Chinese academy of sciences (CASIA v4.0 interval, CASIA v4.0 distance, and IIT Delhi v1.0 iris datasets were used. Experimental results showed the optimal segmentation of the proposed IrisDenseNet and its excellent performance over existing algorithms for all five datasets.

    Caesium uptake by plant roots has been normally associated with the uptake of potassium as the potassium transport systems present in plants have also the capacity to transport caesium. Three grass species (Eragrostis curvula, Cynodon sp and Distichlis spicata) growing in seminatural grassland of central Argentina were selected to study their capability to incorporate Cs+ (and K+) using electrophysiological techniques. Although the 137Cs soil inventory ranged between 328-730 Bq m-2 in this region, no 137Cs activity was detected in these plants. However, all the species, submitted previously to K+ starvation, showed the uptake of both Cs+ and K+ when micromolar concentrations of these cations were present in the medium. The uptake showed saturation kinetics for both cations that could be fitted to the Michelis-Menten model. KM values were smaller for K+ than for Cs+, indicating a higher affinity for the first cation. The presence of increasing K+ concentrations in the assay medium inhibited Cs+ uptake in Cynodon sp., as expected if both cations are transported by the same transport systems. This effect is due to the competition of both ions for the union sites of the high affinity potassium transporters. In field situation, where soil concentration of Cs+ is smaller than K+ concentration, is then expectable that caesium activity in plants is not detectable. Nevertheless, the studied plants would have the capacity to incorporate caesium if its availability in soil solution increases. In addition, studies of Cs/K interaction can help us to understand the variability in transfer factors.

    An ethnobotanical study was conducted from October 2005 to June 2006 to investigate the uses of medicinal plants by people in Zegie Peninsula, northwestern Ethiopia. Information was gathered from 200 people: 70 female and 130 males, using semistructured questionnaire. Of which, six were male local healers. The informants, except the healers, were selected randomly and no appointment was made prior to the visits. Informant consensus factor (ICF) for category of ailments and the fidelity level (FL) of the medicinal plants were determined. Sixty-seven medicinal plants used as a cure for 52 ailments were documented. They are distributed across 42 families and 64 genera. The most frequently utilized plant part was the underground part (root/rhizome/bulb) (42%). The largest number of remedies was used to treat gastrointestinal disorder and parasites infections (22.8%) followed by external injuries and parasites infections (22.1%). The administration routes are oral (51.4%), external (38.6%), nasal (7.9%), and ear (2.1%). The medicinal plants that were presumed to be effective in treating a certain category of disease, such as 'mich' and febrile diseases (0.80) had higher ICF values. This probably indicates a high incidence of these types of diseases in the region, possibly due to the poor socio-economic and sanitary conditions of this people. The medicinal plants that are widely used by the local people or used as a remedy for a specific ailment have higher FL values (Carissa spinarum, Clausena anisata, Acokanthera schimperi, Calpurnia aurea, Ficus thonningii, and Cyphostemma junceum) than those that are less popular or used to treat more than one type of ailments (Plumbago zeylanicum, Dorstenia barnimiana).

  2. National steel tries wheeling

    In 1989, National Steel felt the need to take the next step to make its Detroit-based division, Great Lakes Steel, more competitive in the world flat-rolled steel market. In 1988, Great Lakes Steel started flowing natural gas through the first fully litigated bypass (Competitive Sourcing Option) of a local distribution company. In 1989, the second connection with the new supply route for gas transportation, Panhandle Eastern had started flowing and the LDC, Michigan Consolidated Gas Co. (MichCon) had pulled out their piping previously serving the plants. Since we had been able to structure a fully reliable supply route, storage and balancing program for gas in the face of such strong opposition by the LDC, the author felt it was time to attack the next singularly sourced major commodity, electricity. Electricity, at this major integrated steel plant, represented approximately 7% of plant cost yearly. Yet being monopolized, Great Lakes Division (GLD) could not multiple source this commodity like it does with its other 93% of costs, except for labor (25% of the 93%). Multiple sourcing is done to bring competitive pressure to suppliers and to diversify supplies and protect plant operation in the event of failure by one supplier. This paper describes National Steel's strategy to reduce the cost of power, at the minimum of capital costs, the most expedient way possible, that does not sacrifice any major long-term potential cost improvements. The results show that competitively priced power is available across the mid-west, at prices well below many state regulated electric utilities, for at least 5 to 15 years, but with major obstacles in obtaining transmission access

  3. Shade treatment affects structure and recovery of invasive C4 African grass Echinochloa pyramidalis.

    Echinochloa pyramidalis (Lam.) Hitchc. & Chase is an African grass with C4 photosynthesis, high biomass production, and high vegetative propagation that is tolerant to grazing and able to grow in flooded and dry conditions. Thus, it is highly invasive in tropical freshwater marshes where it is intentionally planted by ranchers to increase cattle production. This invasion is reducing plant biodiversity by increasing the invader's aerial coverage, changing wetland hydrology and causing soil physicochemical changes such as vertical accretion. Reducing the dominance of this species and increasing the density of native wetland species is a difficult, expensive, and time-consuming process. We applied a series of disturbance treatments aimed at eliminating E. pyramidalis and recovering the native vegetation of a partially invaded freshwater marsh. Treatments included physical (cutting, soil disking, transplanting individuals of the key native species Sagittaria lancifolia subsp. media (Micheli) Bogin, and/or reducing light with shade mesh) and/or chemical (spraying Round-Up™ herbicide) disturbances. At the end of the experiment, four of the five treatments used were effective in increasing the cover and biomass of native species and reducing that of E. pyramidalis. The combination of these treatments should be used to generate a proposal for the restoration of tropical wetlands invaded by non-native grasses. A promising treatment is using soil disked to soften the soil and destroy belowground structures such as roots and rhizomes. This treatment would be more promising if combined with the use of shade cloth. If it is desirable not to impact the soil or if there is not enough budget to make an effort to include active restoration disking soil, the use of shade cloth will suffice, although the recovery of native vegetation will be slower.

    The Alma area consists of 30 square miles in the northwestern part of Gratiot County, Mich. It is an area of slight relief gently rolling hills and level plains and is an important agricultural center in the State.The Saginaw formation, which forms the bedrock surface in part of the area, is of relatively low permeability and yields water containing objectionable amounts of chloride. Formations below the Saginaw are tapped for brine in and near the Alma area.The consolidated rocks of the Alma area are mantled by Pleistocene glacial deposits, which are as much as 550 feet thick where preglacial valleys were eroded into the bedrock. The glacial deposits consist of till, glacial-lake deposits, and outwash. Till deposits are at the surface along the south-trending moraines that cross the area, and they underlie other types of glacial deposits at depth throughout the area. The till deposits are of low permeability and are not a source of water to wells, though locally they include small lenses of permeable sand and gravel.In the western part of the area, including much of the city of Alma, the glacial-lake deposits consist primarily of sand and are a source of small supplies of water. In the northeastern part of the area the lake deposits are predominantly clayey and of low permeability.Sand and gravel outwash yields moderate and large supplies of water within the area. Outwash is present at the surface along the West Branch of the Pine River. A more extensive deposit of outwash buried by the lake deposits is the source of most of the ground water pumped at Alma. The presence of an additional deposit of buried outwash west and southwest of the city is inferred from the glacial history of the area. Additional water supplies that may be developed from these deposits are probably adequate for anticipated population and industrial growth.Water levels have declined generally in the vicinity of the city of Alma since 1920 in response to pumping for municipal and industrial

    The Michigan Geological Repository for Research and Education (MGRRE), part of the Department of Geosciences at Western Michigan University (WMU) at Kalamazoo, Michigan, established MichCarb—a geological carbon sequestration resource center by: • Archiving and maintaining a current reference collection of carbon sequestration published literature • Developing statewide and site-specific digital research databases for Michigan’s deep geological formations relevant to CO2 storage, containment and potential for enhanced oil recovery • Producing maps and tables of physical properties as components of these databases • Compiling all information into a digital atlas • Conducting geologic and fluid flow modeling to address specific predictive uses of CO2 storage and enhanced oil recovery, including compiling data for geological and fluid flow models, formulating models, integrating data, and running the models; applying models to specific predictive uses of CO2 storage and enhanced oil recovery • Conducting technical research on CO2 sequestration and enhanced oil recovery through basic and applied research of characterizing Michigan oil and gas and saline reservoirs for CO2 storage potential volume, injectivity and containment. Based on our research, we have concluded that the Michigan Basin has excellent saline aquifer (residual entrapment) and CO2/Enhanced oil recovery related (CO2/EOR; buoyant entrapment) geological carbon sequestration potential with substantial, associated incremental oil production potential. These storage reservoirs possess at least satisfactory injectivity and reliable, permanent containment resulting from associated, thick, low permeability confining layers. Saline aquifer storage resource estimates in the two major residual entrapment, reservoir target zones (Lower Paleozoic Sandstone and Middle Paleozoic carbonate and sandstone reservoirs) are in excess of 70-80 Gmt (at an overall 10% storage efficiency factor; an approximately

    In 2008, the U.S. Geological Survey (USGS), Woods Hole Coastal and Marine Science Center (WHCMSC), in cooperation with the U.S. Army Corps of Engineers conducted a geophysical and sampling survey of the riverbed of the Upper St. Clair River between Port Huron, Mich., and Sarnia, Ontario, Canada. The objectives were to define the Quaternary geologic framework of the riverbed of the St. Clair River to evaluate the relationship between morphologic change of the riverbed and underlying stratigraphy. This report presents the geophysical and sample data collected from the St. Clair River, May 29-June 6, 2008, as part of the International Upper Great Lakes Study, a 5-year project funded by the International Joint Commission of the United States and Canada to examine whether physical changes in the St. Clair River are affecting water levels within upper Great Lakes, to assess regulation plans for outflows from Lake Superior, and to examine the potential effect of climate change on the Great Lakes water levels (http://www.iugls.org). This document makes available the data that were used in a separate report, U.S. Geological Survey Open-File Report 2009-1137, which detailed the interpretations of the Quaternary geologic framework of the region. This report includes a description of the high-resolution acoustic and sediment-sampling systems that were used to map the morphology, surficial sediment distribution, and underlying geology of the Upper St. Clair River during USGS field activity 2008-016-FA (http://quashnet.er.usgs.gov/cgi-bin/datasource/public_ds_info.pl?fa=2008-016-FA). Video and photographs of the riverbed were also collected and are included in this data release. Future analyses will be focused on substrate erosion and its effects on river-channel morphology and geometry. Ultimately, the International Upper Great Lakes Study will attempt to determine where physical changes in the St. Clair River affect water flow and, subsequently, water levels in the Upper Great

    Szentgyörgyi, Rudolf

    2013-12-01

    Full Text Available This paper is part of the author’s series of papers presenting and analysing personal names in the Deed of Foundation of Tihany Abbey. In medieval Hungarian sources, three layers of hagionyms (‘saints’ names’ can be discerned: 1. Hagionyms proper. The denotatum of the name is the particular saint. 2. Patrocinies in the strict sense. These are created by metonymic extension of the saint’s name to the church (less frequently, the religious community of which the saint is the patron. 3. Place names (typically names of settlements based on patrocinies. Given that these three uses can be traced back to one another, in-between cases can also be found. In the text of the Deed of Foundation of Tihany Abbey, examples of all three types can be attested. Although it is a transitional case as far as its connotation is concerned, I take the following to be a hagionym proper: “sanct mari sanctique aniani episcopi & confessoris (sc. ecclesia” – ‘(church dedicated to the Holy Virgin and St Anianus, bishop and confessor’. The following examples represent patrocinies in the strict sense: “qu simul ad sanctum clementem terminantur”– ‘both (roads end at St Clement’; “tercia namque sancti mich(aelis” – ‘the third (lake belongs to St Michael’; and on the verso of the document: “sanct[] mari scilicet & sancti aniani” – ‘(ecclesiastic objects of the Holy Virgin and St Anianus’. An instance of a settlement name based on a patrociny is the name of Tihany itself. We can observe that both the Deed of Foundation of Tihany Abbey and the medieval practice of writing charters in general use names of the first two types exclusively in Latin (alternatively, Greek, whereas names of settlements based on patrocinies are typically mentioned in Hungarian (or in the relevant vernacular. In this, medieval ecclesiastic and official use of names certainly follows the system of name use of theonyms.

  10. Copepod colonization of organic and inorganic substrata at a deep-sea hydrothermal vent site on the Mid-Atlantic Ridge

    The few existing studies on deep-sea hydrothermal vent copepods indicate low connectivity with surrounding environments and reveal high endemism among vents. However, the finding of non-endemic copepod species in association with engineer species at different reduced ecosystems poses questions about the dispersal of copepods and the colonization of hydrothermal vents as well as their ecological connectivity. The objective of this study is to understand copepod colonization patterns at a hydrothermal vent site in response to environmental factors such as temperature and fluid flow as well as the presence of different types of substrata. To address this objective, an in situ experiment was deployed using both organic (woods, pig bones) and inorganic (slates) substrata along a gradient of hydrothermal activity at the Lucky Strike vent field (Eiffel Tower, Mid-Atlantic Ridge). The substrata were deployed in 2011 during the MoMARSAT cruise and were recovered after two years in 2013. Overall, copepod density showed significant differences between substrata types, but was similar among different hydrothermal activity regimes. Highest densities were observed on woods at sites with moderate or low fluid input, whereas bones were the most densely colonized substrata at the 2 sites with higher hydrothermal influence. Although differences in copepod diversity were not significant, the observed trends revealed overall increasing diversity with decreasing temperature and fluid input. Slates showed highest diversity compared to the organic substrata. Temperature and fluid input had a significant influence on copepod community composition, resulting in higher similarity among stations with relatively high and low fluid inputs, respectively. While vent-specialists such as dirivultids and the tegastid Smacigastes micheli dominated substrata at high vent activity, the experiment demonstrated increasing abundance and dominance of non-vent taxa with decreasing temperature and fluid

With multiple (or nonexistent definitions in the literature, however, the concept needs clarification. The primary aim of this study was to analyze the representations and transformations experienced by health care professionals in the course of TPE training in order to characterize educative attitude. We conducted an exploratory qualitative study using several narrative research-based tools with participants of two TPE continuing education courses. We then performed an inductive thematic analysis. Thirty-three people participated in the study; the majority were women (n=29, nurses (n=17 working in a hospital setting (n=28.

    The U.S. Geological Survey (USGS) cooperated with the U.S. Environmental Protection Agency and the U.S. Fish and Wildlife Service on a study to identify the occurrence of chemicals of emerging concern (CECs) in water and bottom-sediment samples collected during 2010–11 at sites in seven areas of concern (AOCs) throughout the Great Lakes. Study sites include tributaries to the Great Lakes in AOCs located near Duluth, Minn.; Green Bay, Wis.; Roches­ter, N.Y.; Detroit, Mich.; Toledo, Ohio; Milwaukee, Wis.; and Ashtabula, Ohio. This report documents the collection meth­ods, analyses methods, quality-assurance data and analyses, and provides the data for this study. Water and bottom-sediment samples were analyzed at the USGS National Water Quality Laboratory in Denver, Colo., for a broad suite of CECs. During this study, 135 environmental and 23 field dupli­cate samples of surface water and wastewater effluent, 10 field blank water samples, and 11 field spike water samples were collected and analyzed. Sixty-one of the 69 wastewater indicator chemicals (laboratory method 4433) analyzed were detected at concentrations ranging from 0.002 to 11.2 micrograms per liter. Twenty-eight of the 48 pharmaceuticals (research method 8244) analyzed were detected at concentrations ranging from 0.0029 to 22.0 micro­grams per liter. Ten of the 20 steroid hormones and sterols analyzed (research method 4434) were detected at concentrations ranging from 0.16 to 10,000 nanograms per liter. During this study, 75 environmental, 13 field duplicate samples, and 9 field spike samples of bottom sediment were collected and analyzed for a wide variety of CECs. Forty-seven of the 57 wastewater indicator chemicals (laboratory method 5433) analyzed were detected at concentrations ranging from 0.921 to 25,800 nanograms per gram. Seventeen of the 20 steroid hormones and sterols (research method 6434) analyzed were detected at concentrations ranging from 0.006 to 8,921 nanograms per gram. Twelve of

Patients with type 2 diabetes show a variety of clinical features, including different "phenotypes" of hyperglycemia (eg, fasting/preprandial or postprandial. Thus, the best treatment choice is sometimes difficult to make, and treatment initiation or optimization is postponed. This situation may explain why, despite the existing complex therapeutic armamentarium and guidelines for the treatment of type 2 diabetes, a significant proportion of patients do not have good metabolic control and at risk of developing the late complications of diabetes. The Italian Association of Medical Diabetologists has developed an innovative personalized algorithm for the treatment of type 2 diabetes, which is available online. According to the main features shown by the patient, six algorithms are proposed, according to glycated hemoglobin (HbA1c, ≥9% or ≤9%, body mass index (≤30 kg/m2 or ≥30 kg/m2, occupational risk potentially related to hypoglycemia, chronic renal failure, and frail elderly status. Through self-monitoring of blood glucose, patients are phenotyped according to the occurrence of fasting/preprandial or postprandial hyperglycemia. In each of these six algorithms, the gradual choice of

    The U.S. Geological Survey (USGS), in cooperation with the city of Big Rapids, investigated the environmental effects of removal of a dam-foundation remnant and downstream cofferdam from the Muskegon River in Big Rapids, Mich. The USGS applied a multidiscipline approach, which determined the water quality, sediment character, and stream habitat before and after dam removal. Continuous water-quality data and discrete water-quality samples were collected, the movement of suspended and bed sediment were measured, changes in stream habitat were assessed, and streambed elevations were surveyed. Analyses of water upstream and downstream from the dam showed that the dam-foundation remnant did not affect water quality. Dissolved-oxygen concentrations downstream from the dam remnant were depressed for a short period (days) during the beginning of the dam removal, in part because of that removal effort. Sediment transport from July 2000 through March 2002 was 13,800 cubic yards more at the downstream site than the upstream site. This increase in sediment represents the remobilized sediment upstream from the dam, bank erosion when the impoundment was lowered, and contributions from small tributaries between the sites. Five habitat reaches were monitored before and after dam-remnant removal. The reaches consisted of a reference reach (A), upstream from the effects of the impoundment; the impoundment (B); and three sites below the impoundment where habitat changes were expected (C, D, and E, in downstream order). Stream-habitat assessment reaches varied in their responses to the dam-remnant removal. Reference reach A was not affected. In impoundment reach B, Great Lakes and Environmental Assessment Section (GLEAS) Procedure 51 ratings went from fair to excellent. For the three downstream reaches, reach C underwent slight habitat degradation, but ratings remained good; reach D underwent slight habitat degradation with ratings changing from excellent to good; and, in an area

    Full Text Available The author provides a historiographic synthesis to propose a chronology of choices of capital investments in Naples during the period of Spanish dominion. During the first half of the sixteenth century (Giulio Fenicia, a diminution of international Mediterranean commerce originating in Naples takes place, giving way to commerce focused exclusively on the needs of Spanish realms. During the second, half of the sixteenth century (Roberto Mantelli, a massive investment of Neopolitan capital in the state's rents comes into play, an investment assured primarily by Genoes and titled nobility. In the first half of the seventeenth century (Rosario Villari, a refeudalization of the rural areas takes place, building from first steps under the administration of the crown of Naples, and gaining renewed impetus from other administrative corners of the Spanish crown. During the second half of the seventeenth century (Michèle Benaiteau, there is a decrease in tensions between the seigneurs and their vassals, most particularly after the population reduction in the wake of the plague of 1656; in the following century, a peaceful transition from a «moral economy» to a «commercial economy» takes place in the exploitation of lands. Following this periodization, it is the reign of Philip II that emerges as the point where economic investment becomes the dominant factor. To attribute this to ideological and cultural rigidity stemming from the Spanish monarchy's dominance seems an oversimplification. To give just one example, the export of wheat from Sicily and Pouilles, which thrived in the beginning of the sixteenth century, decreased thereafter due to the sizeable increase in population (Maurice Aymard. Nonetheless, it is clear that the crown of Naples, once integrated into the Spanish monarchy, favored the state's rents and the reinvigoration of feudal systems. This conception should always be contemplated from the vantage point of a social structure that

    A computer package, GeoSteamNet, was developed to simulate steam transport in a pipeline network of a geothermal field. The fluid motion is governed by the following basic principles: conservation of mass, linear momentum principle (Newton's second law or the Navier Stokes equations), and the first and second laws of thermodynamics. The second law of thermodynamics defines the direction of a spontaneous process, which is indirectly validated in the algorithm as vapor flows from high-to-low pressure, and heat flows from high-to-low temperatures. The nonlinear equations are solved with the Newton-Raphson method. Using the ActiveX component OrificeMeter, the steam-flow balance was calculated for power plants U-15 and U-16 in Los Azufres Geothermal Field, Mich., in February 2009. U-15 was fed by the production wells AZ-04, AZ-28, AZ-30, AZ-65D, and AZ-66, whereas wells AZ-28A, AZ-45, AZ-56, AZ-67, AZ-69D were connected to U-16. The analytical error is within {+-}4%, which is acceptable for practical purposes for steam-supply management, considering the uncertainties in parameters, such as pressure, temperature, pressure fluctuation at the wellhead, etc. The steam simulation results by GeoSteamNet for a hypothetical-pipeline network in a geothermal system with two production wells and a power plant illustrate its functionality. Several points need to be emphasized. For a specific geometry-pipeline network, there is only a certain amount of mass (vapor) that can be transported at a given pressure at the wellheads and the power plant. The construction and modification of a pipeline network is very expensive and the production of geothermal wells depends on many natural factors; therefore, there is need to conduct a tolerance study for each component of the network. A simulation study of the virtual-pipeline network for the design of a geothermal power plant can save money, effort, and time.

    between the P and S velocity models. We find that average P velocities in the focal zone are higher than those around it. High values concentrate along the main active fault with strike of 169 degrees. The model of the P-to-S ratio shows several distinct structures. An area of high P-to-S ratio is mainly identified with the focal zone, and an area of low P-to-S ratio is above the focal zone. Past studies of the P-to-S ratio have linked high ratios with areas of high fracturing and fluid concentration, and low ratios with low permeability and low fluid content. Following this interpretation, the resolved P-to-S ratio model suggests a low permeability layer just above the focal zone. This layer probably acts as a low permeability cap, leading to a change in the stress field and subsequent fracturing. The base of this layer corresponds with the shallowest ruptures. In addition, high ratios follow the fault plane, suggesting high fluid concentration in the focal zone. References: Calò, M., C. Dorbath, F. H. Cornet and N. Cuenot, 2011. Geophys. J.

    The coast of the Mexican Pacific is one of the seismic areas more active of the world due to the subduction of the badges of Coconuts and Rivera under the badge of North America. The earthquakes that happen in this part of Mexico they are of great magnitude and they affect to the central plateau of the country where finds the biggest population density. On the other hand the coast of the Gulf of Mexico presents one relatively low seismic activity. It is in this region where it is the nuclear plant of Laguna Verde (PNLV) and the studies of seismicity of the area should be carried out for questions of nuclear security. One carries out a study of fluctuations of the concentration of the radon in floor and it dilutes underground in the mentioned areas using accustomed to detectors of nuclear appearances (LR-115). Possibly they were also used detecting automatic (Clipperton sounds out). In some cases it was analysed the gamma radiation in soil using thermoluminescent dosemeters (CaSO 4 : Dy + Ptfe). The mineralogical composition of rock samples was obtained, by means of technical conventional and Electron scanning microscopy and an X-ray diffractometer. The study one carries out along the coast of Guerrero, from Guacamayas, Mich. until Marquelia, Gro., of 1993 at 1998 and in the coast of the Gulf of Mexico, in the PNLV and their surroundings, of 1994 at 1996. The fluctuations of the radon concentration and of the gamma radiation, were analysed in function of the local seismic activity, the meteorological parameters and those characteristic geologic. In the area of the PNLV, the results showed that in general the averages of those value of the radon concentration, as much in floor as in water, they were low.

Our primary objective was to report the perception of smokers on the textual health warnings already appearing on tobacco packages in Lebanon versus shocking pictures about the health-related smoking consequences and to evaluate their impact on smoking behaviors and motivation. Methods: A pilot cross-sectional study was undertaken between 2013 and 2015 in five hospitals in Lebanon. Participants answered a questionnaire inquiring about sociodemographic characteristics, chronic respiratory symptoms, smoking behavior and motivation to quit smoking. Only-text warning versus shocking pictures was shown to the smokers during the interview. Results: Exactly 66% of the participants reported that they thought shocking pictorial warnings would hypothetically be more effective tools to reduce/quit tobacco consumption compared to only textual warnings. Also, 31.9% of the smokers who were motivated to stop smoking reported that they actually had stopped smoking for at least 1 month secondary to

  4. MSU Contributes to New Research on Star Formation

    EAST LANSING, Mich. - "Crazy" and "cool" are two of the words Michigan State University astronomer Megan Donahue uses to describe the two distinct "tails" found on a long tail of gas that is believed to be forming stars where few stars have been formed before. Donahue was part of an international team of astronomers that viewed the gas tail with a very long, new observation made by the Chandra X-ray Observatory and detailed it in a paper published this month in the publication Astrophysical Journal. "The double tail is very cool - that is, interesting - and ridiculously hard to explain," said Donahue, a professor in MSU's Department of Physics and Astronomy. "It could be two different sources of gas or something to do with magnetic fields. We just don't know." What is also unusual is the gas tail, which is more than 200,000 light years in length, extends well outside any galaxy. It is within objects such as this that new stars are formed, but usually within the confines of a galaxy. "This system is really crazy because where we're seeing the star formation is well away from any galaxy," Donahue said. "Star formation happens primarily in the disks of galaxies. What we're seeing here is very unexpected." This gas tail was originally spotted by astronomers three years ago using a multitude of telescopes, including NASA's Chandra X-ray Observatory and the SOuthern Astrophysical Research telescope, a Chilean-based observatory in which MSU is one of the partners. The new observations show a second tail, and a fellow galaxy, ESO 137-002, that also has a tail of hot X-ray-emitting gas. How these newly formed stars came to be in this particular place remains a mystery as well. Astronomers theorize this gas tail might have "pulled" star-making material from nearby gases, creating what some have called "orphan stars." "This system continues to surprise us as we get better observations of it," Donahue said. The gas tail is located in the southern hemisphere near a

    Dryer, William R.

    1963-01-01

    The average annual commercial production of whitefish in the U.S. waters of Lake Superior dropped from 2,194,000 pounds in 1879-1908 to 504,000 pounds in 1911-59. The modern production, though far below the earlier, has accounted for more than 10 percent of the total value of the fishery in all but one of the last 20 years. Data are given on growth rate, age and year-class composition, size distribution, and length-weight relation of 1,800 fish collected in 1957-59 at Bayfield, Wis., and Marquette, Whitefish Point, and Dollar Settlement, Mich. Studies of the body-scale relation, sex ratio, and age and size at maturity were limited to fish collected at Bayfield. The age composition and mean age varied widely by port and year of capture. Oldest fish were those of the 1957 Bayfield samples which were dominated by age group VII and averaged 5.5 years old. The youngest were from Whitefish Point in 1959; age-group III was dominant, and the mean age was 3.2 years. The evidence on the strength of year classes was not clear-cut, but it was obvious that fluctuations in stocks of different areas were largely independent. The percentage of legal-size fish (17 inches or longer) in age groups ranged widely; only 8.6 percent of the V group were legal in the 1957 Bayfield collections, whereas 100 percent of fish of the same age were legal in the 1957-59 collections from Whitefish Point. The weight of whitefish in the combined samples increased as the 3.2408 power of the length. The growth rate from the fastest to the slowest growing stocks ranked as follows: Whitefish Point; Dollar Settlement and Marquette (fish from the two ports reversed ranks after 3 years); Bayfield. The major differences in growth in length among the various stocks occurred during the first years of life. Beyond the fifth year the annual increments were nearly the same in all stocks. The whitefish from Whitefish Point, Dollar Settlement, and Marquette are among the fastest growing in the Great Lakes. The

    It is of course a great honor to receive the Holmes medal from EGU. As past (founding) treasurer and later president of EUG, the medal carries special significance for me. It may be a good time to look back on the scientific path I have followed, pursuing research in the geosciences, with outstanding support from a number of family members (foremost my wife Michèle), mentors, colleagues and students. Chance, not planning, led me to attend a French school that trained mining engineers, then a US University that made me fall in love with geophysics and plate tectonics at a time when this scientific revolution was still going on, and finally the marvelous Institut de Physique du Globe de Paris (IPGP), where I have spent the rest of my career to this day. To pursue on this path, I selected the rather separate fields of paleomagnetism (then linked to geology) and geomagnetism (then linked to physics). I have devoted much of my time to make sure that the two specialties would closely interact, including in the structure of our groups at IPGP. Geo- and paleo-magnetism have turned out (in a way reminiscent of geochemistry) to be powerful tools to explore a broad range of exciting scientific questions. Equipped with them, I have had the pleasure and good fortune to navigate from the discovery of geomagnetic secular variation impulses (with Jean-Louis Le Mouël), now inelegantly called "geomagnetic jerks", to that of propagating rifting of continents in the Afar depression, to fascinating work on the India-Asia collision in the Tibetan plateau and the Cenozoic paleogeography of the Indian ocean bordering continents, to the reconstruction of synthetic apparent polar wander paths for major continental masses (with Jean Besse) that have been widely used, to the understanding of the significance of the volume, age and short duration of massive flood basalt volcanism in the Deccan traps of India and their potential link to the biological mass extinction at the Cretaceous

Between-subject variability indicates the presence of mediators and moderators in the BMI–QoL association. This study aimed to examine the roles of body image discrepancy (BID and subjective norm (SN as potential mediators and moderators. Subjects and methods: In 2012, 3,016 volunteers (aged ≥18 years participated in a community-based survey conducted in the French-speaking region of Belgium. Participation was enhanced using a large multimedia campaign (which was supported by a large network of recruiters that employed the nonstigmatizing slogan, “Whatever your weight, your opinion will count”. Participants were invited to complete a web-based questionnaire on their weight-related experiences. Self-reported measures were used to calculate each participant’s BMI, BID, SN, and QoL (a French obesity-specific QoL questionnaire was used to calculate the participants’ physical dimension of QoL scores [PHY-QoL], psychosocial dimension of QoL scores [PSY/SOC-QoL], and their total scores. The covariates included gender, age, subjective economic status, level of education, household size, and perceived health. The mediation/moderation tests were based on Hayes’ method. Results: Tests showed that the relationships between BMI and PHY-QoL, PSY/SOC-QoL, and TOT-QoL were partially mediated by BID

    . Lastly, it describes several categories of limitations and discusses ways of extending the regional model to address issues at the local scale. Results of the simulations portray a regional groundwater-flow system that, over time, has largely maintained its natural predevelopment configuration but that locally has been strongly affected by well withdrawals. The quantity of rainfall in the Lake Michigan Basin and adjacent areas supports a dense surface-water network and recharge rates consistent with generally shallow water tables and predominantly shallow groundwater flow. At the regional scale, pumping has not caused major modifications of the shallow flow system, but it has resulted in decreases in base flow to streams and in direct discharge to Lake Michigan (about 2 percent of the groundwater discharged and about 0.5 cubic foot per second per mile of shoreline). On the other hand, well withdrawals have caused major reversals in regional flow patterns around pumping centers in deep, confined aquifers - most noticeably in the Cambrian-Ordovician aquifer system on the west side of Lake Michigan near the cities of Green Bay and Milwaukee in eastern Wisconsin, and around Chicago in northeastern Illinois, as well as in some shallow bedrock aquifers (for example, in the Marshall aquifer near Lansing, Mich.). The reversals in flow have been accompanied by large drawdowns with consequent local decrease in storage. On the west side of Lake Michigan, groundwater withdrawals have caused appreciable migration of the deep groundwater divides. Before the advent of pumping, the deep Lake Michigan groundwater-basin boundaries extended west of the Lake Michigan surface-water basin boundary, in some places by tens of miles. Over time, the pumping centers have replaced Lake Michigan as the regional sink for the deep flow system. The regional model is intended to support the framework pilot study of water availability and use for the Great Lakes Basin (Reeves, in press).

    The coast of the Mexican Pacific is one of the seismic areas more active of the world due to the subduction of the badges of Coconuts and Rivera under the badge of North America. The earthquakes that happen in this part of Mexico they are of great magnitude and they affect to the central plateau of the country where finds the biggest population density. On the other hand the coast of the Gulf of Mexico presents one relatively low seismic activity. It is in this region where it is the nuclear plant of Laguna Verde (PNLV) and the studies of seismicity of the area should be carried out for questions of nuclear security. One carries out a study of fluctuations of the concentration of the radon in floor and it dilutes underground in the mentioned areas using accustomed to detectors of nuclear appearances (LR-115). Possibly they were also used detecting automatic (Clipperton sounds out). In some cases it was analysed the gamma radiation in soil using thermoluminescent dosemeters (CaSO{sub 4}: Dy + Ptfe). The mineralogical composition of rock samples was obtained, by means of technical conventional and Electron scanning microscopy and an X-ray diffractometer. The study one carries out along the coast of Guerrero, from Guacamayas, Mich. until Marquelia, Gro., of 1993 at 1998 and in the coast of the Gulf of Mexico, in the PNLV and their surroundings, of 1994 at 1996. The fluctuations of the radon concentration and of the gamma radiation, were analysed in function of the local seismic activity, the meteorological parameters and those characteristic geologic. In the area of the PNLV, the results showed that in general the averages of those value of the radon concentration, as much in floor as in water, they were low. A station located in a flaw area (New Ranch) the one that I present the values was but high of radon concentration, corresponding those but first floor to the PNLV. The seismic activity during the one period of sampling was sporadic and of low intensity and alone

    The Kalamazoo report area includes about 150 square miles of Kalamazoo County, Mich. The area is principally one of industry and commerce, although agriculture also is of considerable importance. It has a moderate and humid climate and lies within the Lake Michigan “snow belt”. Precipitation averages about 35 inches per year. Snowfall averages about 55 inches. The surface features of the area were formed during and since the glacial epoch and are classified as outwash plain, morainal highlands, and glaciated channels or drainageways. The area is formed largely on the remnants of an extensive outwash plain, which is breached by the Kalamazoo River in the northeastern part and is dissected elsewhere by several small tributaries to the river. Most of the land drained by these tributaries lies within the report area. A small portion of the southern part drains to the St. Joseph River. The Coldwater shale, which underlies the glacial deposits throughout the area, and the deeper bedrock formations are not tapped for water by wells and they have little or no potential for future development. Deposits of glacial drift, which are the source of water to all the wells in the area, have considerable potential for future development. These deposits range in thickness from about 40 feet along the Kalamazoo River to 350 feet where valleys were eroded in the bedrock surface. Permeable outwash and channel deposits are the sources of water for wells of large capacity. The moraines are formed dominantly by till of lower permeability which generally yields small supplies of water, but included sand and gravel beds of higher permeability yield larger supplies locally. The aquifers of the Kalamazoo area are recharged by infiltration of rainfall and snowmelt and by infiltration of surface waters induced by pumping of wells near the surface sources. Water pumped from most of the municipal well fields is replenished in part by such induced infiltration. Many of the industrial wells

Consequently, seasonal changes in the {sup 40}K soil-to-plant transfer factors were found. Additionally, Cs{sup +} and K{sup +} roots uptake was assessed for each grass species using electrophysiological techniques. The kinetics uptake, for both cations, was fitted following the Michelis-Menten model, suggesting the presence high affinity transport systems and a higher affinity for K{sup +} than for Cs{sup +}. Finally, the contribution to the external gamma dose rate was assessed. For {sup 40}K and {sup 226}Ra contributions the dose factors suggested by the UNSCEAR were applied, while for {sup 137}Cs a Monte Carlo algorithm (Dages) was used. The values obtained are, 32.2±2.5 nGy h{sup -1} for {sup 40}K, 9.2±1.2 nGy h{sup -1} for {sup 226}Ra and 0.15±0.03 nGy h{sup -1} for {sup 137}Cs. (authors)

Youth resistance training: Updated position statement paper from the National Strength and Conditioning Association. J Strength Cond Res 23(5): S60-S79, 2009-Current recommendations suggest that school-aged youth should participate daily in 60 minutes or more of moderate to vigorous physical activity that is developmentally appropriate and enjoyable and involves a variety of activities (). Not only is regular physical activity essential for normal growth and development, but also a physically active lifestyle during the pediatric years may help to reduce the risk of developing some chronic diseases later in life (). In addition to aerobic activities such as swimming and bicycling, research increasingly indicates that resistance training can offer unique benefits for children and adolescents when appropriately prescribed and supervised (). The qualified acceptance of youth resistance training by medical, fitness, and sport organizations is becoming universal ().Nowadays, comprehensive school-based programs are specifically designed to enhance health-related components of physical fitness, which include muscular strength (). In addition, the health club and sport conditioning industry is getting more involved in the youth fitness market. In the U.S.A., the number of health club members between the ages of 6 and 17 years continues to increase () and a growing number of private sport conditioning centers now cater to young athletes. Thus, as more children and adolescents resistance train in schools, health clubs, and sport training centers, it is imperative to determine safe, effective, and enjoyable practices by which resistance training can improve the health, fitness, and sports performance of younger populations.The National Strength and Conditioning Association (NSCA) recognizes and supports the premise that many of the benefits associated with adult resistance training

    Full Text Available OBJETIVO: Caracterizar a população de profissionais do sexo em atividade em Ribeirão Preto, Brasil, segundo variáveis demográficas e socioeconômicas, e estudar os fatores de risco para doenças sexualmente transmissíveis nessa população. MÉTODOS: Foram visitados todos os locais de prática de prostituição identificados na cidade. Os participantes responderam um questionário que levantava informações sócio-demográficas e fatores de risco para doenças sexualmente transmissíveis. Foi responsável pelas entrevistas uma assistente social que há mais de 5 anos desenvolvia atividades educativas junto aos profissionais do sexo de Ribeirão Preto. RESULTADOS: As 449 prostitutas, 53 travestis e 13 michês estudados representam uma população jovem, de baixa escolaridade, reduzido nível socioeconômico e grande mobilidade espacial. Em relação às prostitutas, os travestis apresentaram risco significativamente mais elevado para doenças sexualmente transmissíveis, o qual se traduz por diferenças em termos do tempo de trabalho, número médio de parceiros por dia, antecedente de doenças sexualmente transmissíveis ulcerativas, prática de sexo anal, uso de drogas ilícitas não-injetáveis, especialmente o crack, e antecedente de prisão. A exposição a bebidas alcoólicas foi o único fator de risco mais freqüente entre as prostitutas. O uso de preservativo com parceiros fixos foi menos comum do que nas relações sexuais comerciais, tanto em prostitutas como em travestis. CONCLUSÕES: Os profissionais do sexo de Ribeirão Preto, especialmente os travestis, representam uma população socialmente marginalizada e de alto risco para doenças sexualmente transmissíveis. É necessário que os serviços de saúde pública dediquem mais atenção aos profissionais do sexo, tanto em termos de programas preventivos como de realização de novas investigações que permitam um melhor conhecimento acerca dos fatores de risco espec

    1964-01-01

    This report describes the water resources of Genesee County, Mich., whose principal city is Flint. The sources of water available to the county are the Flint and Shiawassee Rivers and their tributaries, inland lakes, ground water, and Lake Huron. The withdrawal use of water in the county in 1958 amounted to about 45 mgd. Of this amount, 36 mgd was withdrawn from the Flint River by the Flint public water-supply system. The rest was supplied by wells. At present (1959) the Shiawassee River and its tributaries and the inland lakes are not used for water supply. Flint River water is used for domestic, industrial, and waste-dilution requirements in Flint. About 60 percent of the water supplied by the Flint public water system is used by Flint industry. At least 30 mgd of river water is needed for waste dilution in the Flint River during warm weather.Water from Holloway Reservoir, which has a storage capacity of 5,760 million gallons, is used to supplement low flows in the Flint River to meet water-supply and waste-dilution requirements. About 650 million gallons in Kearsley Reservoir, on a Flint River tributary, is held in reserve for emergency use. Based on records for the lowest flows during the period 1930-52, the Flint River system, with the two reservoirs in operation, is capable of supplying about 60 mgd at Flint, less evaporation and seepage losses. The 1958 water demands exceeded this amount. Development of additional storage in the Flint River basin is unlikely because of lack of suitable storage sites. Plans are underway to supply Flint and most of Genesee County with water from Lake Huron.The principal tributaries of the Flint River in and near Flint could furnish small supplies of water. Butternut Creek, with the largest flow of those studied, has an estimated firm yield of 0.054 mgd per sq mi for 95 percent of the time. The Shiawassee River at Byron is capable of supplying at least 29 mgd for 95 percent of the time.Floods are a serious problem in Flint

    the experimental recorded signatures. 'More traditional' DFT static calculations can be applied to complex objects at interfaces, providing their vibrational spectra, and two papers in this special section illustrate such approaches. Ceccet et al extract first hyperpolarizability tensors from DFT calculations on aliphatic chains and simulate the related VSFG spectra. They also investigate the effect of different functionals on the final signatures. Liegeois et al investigate functionalized surfaces, mainly focusing on IR and Raman spectral features, and provide very precise vibrational assignments depending on chemisorption or physisorption of the adsorbed molecules. We are grateful to all the authors for their contributions to this special section and we hope that readers will enjoy this collection of papers and that they will find further motivation to investigate and understand the complex phenomena occurring at interfaces.
