    Full Text Available The Wujiang River is a tributary of the upper Yangtze River that shows great variations in its flow regime and habitat condition. Dams have been built along the Wujiang River and have altered the habitats profoundly enough that they may give rise to reproductive isolation. To test whether the swimming performance and morphology of the Chinese hook snout carp (Opsariichthys bidens, varied among habitats and whether the possible differences had a genetic basis, we measured the steady and unsteady swimming performance, external body shape and genetic distance among fish collected from both the main and tributary streams of the upper, middle and lower reaches along the river. We also measured the routine energy expenditure (RMR, maximum metabolic rate (MMR, cost of transport (COT and calculated the optimal swimming speed. The steady swimming capacity, RMR, MMR and optimal swimming speed were all higher and the COT was lower in the upper reach or tributary streams compared with the lower reach or main stream. However, unsteady swimming performance showed no variation among collecting sites. Flow regimes as suggested by river slope and water velocity were positively correlated with steady swimming performance but not with unsteady swimming performance. Predation stress were significantly related with body morphology and hence energy cost during swimming but not U(crit value. The fish from only one population (Hao-Kou showed relatively high genetic differentiation compared with the other populations. Fish from the upper reach or tributary streams exhibited improved steady swimming performance through improved respiratory capacity and lower energy expenditure during swimming at the cost of higher maintenance metabolism. There was no correlation between the steady and unsteady swimming performance at either the population or the individual levels. These results suggest that a trade-off between steady and unsteady swimming does not occur in O. bidens.

    Based upon anatomical evidence, Permian aged gigantopterid fossils are in general reconstructed as climbing or scrambling plants. Gigantonoclea, a genus of adpressed gigantopterid foliage from the Permian of northern China, has been reported to co-occur with hook-like organs that were interpreted as indicating a scrambling/climbing habit. We reinvestigated these hook-like structures and re-evaluated the nature of the co-occurrences in context with the flora preserved in each plant-bearing fossil 'bed' in the North China sedimentary succession. New findings show that the species Gigantonoclea hallei probably climbed using specially adapted clusters of compound grappling hook-like shoots borne on the stems. This structural arrangement comprising shoots of hooks is new to the scrambling/climbing concept in gigantopterids. However, a key figured specimen previously reported as showing intermediate hook-tipped leaf morphology on a sole pinnule tip is discounted as such and is reinterpreted as a 'normal' pinnule partially hidden under sediment that results in an unusual appearance to this pinnule tip. Adaptations for climbing or scrambling based upon 'hooked leaves' observed in Gigantonoclea lagrelii are no longer supported and are reinterpreted as incompletely expanded leaves where the vernation process was interrupted. These data weaken prior interpretations of G. lagrelii as a climber/scrambler and raise doubts about the ubiquity of hooks amongst the gigantopterids as structures enabling them to climb or scramble their way through the Permian world.

    Chinese fir (Cunninghamia lanceolata (Lamb.) Hook) is one of the most important coniferous tree species used for timber production in China. Here, we conducted a sequence-related amplified polymorphism (SRAP) primer screening assay with a total of 594 primer combinations, using 22 forward and 27 reverse primers on four repre-sentative Chinese fir genotypes. The obtained results indicated that Chinese fir genomic DNA has a notable amplification bias on the employed forward or reverse primer nucleotides (3' selection bases). Out of the tested primer sets, 35 primer combinations with clearly distin-guished bands, stable amplification, and rich polymorphism were selected and identified as optimal primer sets. These optimal primer pairs gave a total of 379 scorable bands, including 265 polymorphic bands, with an average of 10.8 bands and 7.6 polymorphic bands per primer combination. The produced band number for each optimal primer set ranged from 7 to 14 with a percentage of polymorphic bands spanning from 33.3 to 100.0%. These primer combinations could facilitate the next SRAP analysis assays in Chinese fir.

    Decomposition of stumps in successive rotation of Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.) plantations was studied using a chronosequence approach. The results showed that decomposition rate constant of Chinese fir stump was 0.02695 as calculated from Olson's model. The N content of stump increased during the first two-year decomposition. When the dead stump C/N ratio was 463.2 ± 27.3, the stumps started to release N. The pattern of P release was similar to that for N. However, K content of stumps showed a consistent declining trend over time during the whole decomposition. 13C nuclear magnetic resonance spectroscopy with cross polarization and magic-angle spinning (13C CPMAS-NMR) was used to analyse organic carbon (C) components in decomposing stumps. The 13C CPMAS-NMR spectra of stumps displayed that stump was dominated by cellulose and hemicellulose. The spectra also showed the accumulation of intensity in alkyl C, aromatic C, and carboxyl C spectral regions, which was expected as the labile cellulose and hemicellulose components in O-alkyl C spectral region were selectively decomposed first.

    Background The molecular mechanisms that govern cambial activity in angiosperms are well established, but little is known about these molecular mechanisms in gymnosperms. Chinese fir (Cunninghamia lanceolata (Lamb.) Hook), a diploid (2n  = 2x  = 22) gymnosperm, is one of the most important industrial and commercial timber species in China. Here, we performed transcriptome sequencing to identify the repertoire of genes expressed in cambium tissue of Chinese fir. Methodology/Principal Findings ...

  7. Ion Flux in Roots of Chinese Fir (Cunninghamia lanceolata (Lamb. Hook under Aluminum Stress.

    Directory of Open Access Journals (Sweden)

    Zhihui Ma

    Full Text Available Chinese fir is a tall, fast-growing species that is unique to southern China. In Chinese fir plantations, successive plantings have led to a decline in soil fertility, and aluminum toxicity is thought to be one of the main reasons for this decline. In this study, Non-invasive Micro-test Technology was used to study the effect of aluminum stress on the absorption of 4 different ions in the roots of the Chinese fir clone FS01. The results are as follows: with increased aluminum concentration and longer periods of aluminum stress, the H+ ion flow gradually changed from influx into efflux; there was a large variation in the K+ efflux, which gradually decreased with increasing duration of aluminum stress; and 1 h of aluminum stress uniformly resulted in Ca2+ influx, but it changed from influx to efflux after a longer period of aluminum stress. Changes in the different concentrations of aluminum had the largest influence on Mg2+.

  10. Multipurpose hooks for elastic attachment

    2014-01-01

    Full Text Available As certain bracket systems do not include hooks on premolar brackets for elastic attachment, Kobayashi or custom made ligature hooks have proven as an alternative. However, these hooks tend to bend labially when used with heavy elastics and these elastics can even pop loose from the hooks on mouth opening. The following article describes an innovative multipurpose hook which is simple, stiff and inexpensive and can be used for engagement of class II elastics on premolars in case of missing molars as well as engagement of intermaxillary elastics for settling of occlusion in finishing stages. As the hooks can be prefabricated, this saves a lot of chair side time and is more practical for use in day-to-day orthodontic practice.

  11. Hooke's figurations: a figural drawing attributed to Robert Hooke.

    The experimental philosopher Robert Hooke (1635-1703) is known to have apprenticed to the leading painter Peter Lely on his first arrival in London in the late 1640s. Yet the relevance of Hooke's artistic training to his mature draughtsmanship and identity has remained unclear. Shedding light on that larger interpretive problem, this article argues for the attribution to Hooke of a figural drawing now in Tate Britain (T10678). This attributed drawing is especially interesting because it depicts human subjects and bears Hooke's name functioning as an artistic signature, both highly unusual features for his draughtsmanship. From evidence of how this drawing was collected and physically placed alongside images by leading artists in the early eighteenth century, I suggest how it can offer new insight into the reception of Hooke and his graphic work in the early Enlightenment.

  12. The Hooked Galaxy

    Life is not easy, even for galaxies. Some indeed get so close to their neighbours that they get rather distorted. But such encounters between galaxies have another effect: they spawn new generations of stars, some of which explode. ESO's VLT has obtained a unique vista of a pair of entangled galaxies, in which a star exploded. Because of the importance of exploding stars, and particularly of supernovae of Type Ia [1], for cosmological studies (e.g. relating to claims of an accelerated cosmic expansion and the existence of a new, unknown, constituent of the universe - the so called 'Dark Energy'), they are a preferred target of study for astronomers. Thus, on several occasions, they pointed ESO's Very Large Telescope (VLT) towards a region of the sky that portrays a trio of amazing galaxies. MCG-01-39-003 (bottom right) is a peculiar spiral galaxy, with a telephone number name, that presents a hook at one side, most probably due to the interaction with its neighbour, the spiral galaxy NGC 5917 (upper right). In fact, further enhancement of the image reveals that matter is pulled off MCG-01-39-003 by NGC 5917. Both these galaxies are located at similar distances, about 87 million light-years away, towards the constellation of Libra (The Balance). ESO PR Photo 22/06 ESO PR Photo 22/06 The Hooked Galaxy and its Companion NGC 5917 (also known as Arp 254 and MCG-01-39-002) is about 750 times fainter than can be seen by the unaided eye and is about 40,000 light-years across. It was discovered in 1835 by William Herschel, who strangely enough, seems to have missed its hooked companion, only 2.5 times fainter. As seen at the bottom left of this exceptional VLT image, a still fainter and nameless, but intricately beautiful, barred spiral galaxy looks from a distance the entangled pair, while many 'island universes' perform a cosmic dance in the background. But this is not the reason why astronomers look at this region. Last year, a star exploded in the vicinity of the hook

    This paper offers an insight into the design structure of physics video hooks that were developed by the Science Education Resource design team in the school of education (SOE) in National University of Ireland, Galway (NUI Galway). A hook, is an instructional technique used to stimulate student attention (Hunter 1994, Lemov 2010), interest (Jewett 2013) and engagement (McCrory 2011, Riendeau 2013). The physics video hooks followed a design framework that is illustrated below by breaking down the centre of gravity (COG) hook. Various design principles and elements embedded within the COG hook are presented with examples and the time they occur within the video. The intention of this article is that the design can be replicated and modified to aid teachers and designers in the development of a multitude of classroom based multimedia resources.

    2005-02-01

    Full Text Available Towing hooks generally are assembled to vehicles as accessory. They are used to tow caravans and trailers having no engine, which provide accommodation and haulage of loads, respectively. So, the transport capacity of cars is increased safely. Towing hooks require different constructive structures due to different chassis or monocoque body of each car type; hence they are to be manufactured and assembled in small- or middle-size factories as per order. In this study, three different constructions of towing hook are modelled and structurally analysed. The results obtained are compared with each other to improve the structural strength.

    Microorganisms were first observed by Robert Hooke and Antoni van Leeuwenhoek between 1665 and 1678. In 1665, Hooke published Micrographia, which depicted the details of 60 objects as seen in the microscope. One chapter was devoted to the microfungus Mucor, the first microbe observed by the human eye. Leeuwenhoek, despite having no scientific training, became the first to observe protozoa, red blood cells, the sperm cells of animals, and bacteria, which he described in numerous letters to the Royal Society of London. In 1677, Hooke became Secretary of the Royal Society and, in the same year, confirmed some of Leeuwenhoek's discoveries. The discovery in 2006 of more than 650 pages of Hooke's missing records (the "Hooke Folio") allows us to verify the proceedings of Royal Society meetings and promises to be an important new source of Hooke's views on the renaissance of science in the 17th century.

    The present study conducted a 9-week feeding trial to investigate the effects of threonine (Thr) on the digestion capacity and hepatopancreas gene expression of juvenile blunt snout bream (Megalobrama amblycephala). For this purpose, three tanks (300 litres/tank) were randomly arranged and assigned to each experimental diet. Juvenile fish were fed with diets containing graded Thr levels (0·58, 1·08, 1·58, 2·08 or 2·58 % of the diet) to apparent satiation four times daily. At the end of the feeding trial, the results indicated that hepatopancreas weight, hepatosomatic index, hepatopancreatic protein content, intestinal weight, intestosomatic index and intestinal protein content increased with increasing dietary Thr levels up to 1·58 % and thereafter decreased (Pamylase and lipase elevated as dietary Thr levels increased up to 1·58 % (Pamylase, lipase, target of rapamycin and insulin-like growth factor-I were up-regulated, and the highest values were observed with 1·58 % dietary Thr or 1·58 and 2·08 % dietary Thr, whereas the relative gene expression levels of eukaryotic translation initiation factor 4E-binding protein 2 gradually decreased (P< 0·10) as dietary Thr levels increased up to 1·58 % and thereafter significantly increased (P< 0·05), which could explain that about 1·58 % dietary Thr could improve the growth and development of digestive organs and activities of digestive enzymes of juvenile blunt snout bream.

  4. Short-snouted toothless ichthyosaur from China suggests Late Triassic diversification of suction feeding ichthyosaurs.

    Directory of Open Access Journals (Sweden)

    P Martin Sander

    Full Text Available BACKGROUND: Ichthyosaurs were an important group of Mesozoic marine reptiles and existed from the Early Triassic to the early Late Cretaceous. Despite a great diversity in body shapes and feeding adaptations, all share greatly enlarged eyes, an elongated rostrum with numerous conical teeth, and a streamlined body. METHODOLOGY/PRINCIPAL FINDINGS: Based on new material from China and the restudy of Shastasaurus pacificus, we here reinterpret the classical large-bodied Late Triassic ichthyosaur genus Shastasaurus to differ greatly from the standard ichthyosaurian body plan, indicating much greater morphological diversity and range of feeding adaptations in ichthyosaurs than previously recognized. Phylogenetic analysis indicates a monophyletic clade consisting of the giant Shonisaurus sikanniensis, Guanlingsaurus liangae, and Shastasaurus pacificus to which the genus name Shastasaurus is applied. Shastasaurus liangae comb. nov. is from the Late Triassic (Carnian Xiaowa Formation of Guizhou Province, southwestern China. The species combines a diminutive head with an entirely toothless and greatly reduced snout. The species also has by far the highest vertebral count among ichthyosaurs (86 presacral vertebrae and >110 caudal vertebrae, a count that is also very high for tetrapods in general. A reduced toothless snout and a diminutive head is also apparently present in the giant S. sikanniensis and presumably in S. pacificus. CONCLUSIONS/SIGNIFICANCE: In analogy to many modern odontocetes, Shastasaurus is interpreted as a specialized suction feeder on unshelled cephalopods and fish, suggesting a unique but widespread Late Triassic diversification of toothless, suction-feeding ichthyosaurs. Suction feeding has not been hypothesized for any of the other diverse marine reptiles of the Mesozoic before, but in Shastasaurus may be linked to the Late Triassic minimum in atmospheric oxygen.

    The present is a report of the work that was conducted during my 8-week summer school internship at CERN. The project was centered on the development of an instrumentation tool for the usage of mathematical functions in a scientific application. More specifically, $\\textbf{cptnHook}$ addresses a current issue that arises from the the extensive use of very time-consuming mathematical functions (such as transcendental functions) that results in them accounting for a big portion of their run-time. It is believed that the problem can be addressed with ad-hoc approximations of mathematical functions, for which a clear overview of the usage of the functions in the program is required. $\\textbf{cptnHook}$ approaches this problem by providing a measurement of the use of mathematical functions in a program by hooking into the machine code and probing the arguments of the functions, without modifying the application's source code. The outputs of the tool are provided in ROOT format for further on analysis.

    A gas turbine engine's nozzle structure includes a nozzle support ring, a plurality of shroud segments, and a plurality of airfoil vanes. The plurality of shroud segments are distributed around the nozzle support ring. Each airfoil vane is connected to a corresponding shroud segment so that the airfoil vanes are also distributed around the nozzle support ring. Each shroud segment has a hook engaging the nozzle support ring so that the shroud segments and corresponding airfoil vanes are supported by the nozzle support ring. The nozzle support ring, the shroud segments, and the airfoil vanes may be ceramic.

  10. Regression equations between body and head measurements in the broad-snouted caiman (Caiman latirostris

    2000-01-01

    Full Text Available In the present study, regression equations between body and head length measurements for the broad-snouted caiman (Caiman latirostris are presented. Age and sex are discussed as sources of variation for allometric models. Four body-length, fourteen head-length, and ten ratio variables were taken from wild and captive animals. With the exception of body mass, log-transformation did not improve the regression equations. Besides helping to estimate body-size from head dimensions, the regression equations stressed skull shape changes during the ontogenetic process. All age-dependent variables are also size-dependent (and consequently dependent on growth rate, which is possibly related to the difficulty in predicting age of crocodilians based on single variable growth curves. Sexual dimorphism was detected in the allometric growth of cranium but not in the mandible, which may be evolutionarily related to the visual recognition of gender when individuals exhibit only the top of their heads above the surface of the water, a usual crocodilian behavior.

    The expansion and intensification of agriculture during the past 50 years is unprecedented, and thus environmental problems have been triggered at different scales. These transformations have caused the loss of habitat and biodiversity, and disruption of the structure and functioning of ecosystems. As a result of the expansion of the agricultural frontier in the recent past, many areas of the natural geographic distribution of the local wildlife, among them crocodilians and particularly the broad snouted caiman (Caiman latirostris), are being exposed to contaminants. The present study was designed to evaluate the effect of commercially-mixed glyphosate (RU) on some parameters of the immune system of C. latirostris. Two groups of caimans were exposed for two months to different concentrations of RU recommended for its application in the field, while one group was maintained as an unexposed control. The RU concentration was progressively decreased through the exposure period to simulate glyphosate degradation in water. After exposure, total and differential white blood cell (WBC), and complement system activity (CS) were determined. In addition, the animals were injected with a solution of lipopolysaccharide (LPS) from Escherichia coli to trigger an immune response and evaluate the parameters associated with it. The results showed that an effect of the herbicide on CS was observed, as animals exposed to RU showed a lower CS activity than animals from the negative control (NC) but not in total WBC. In the case of leukocyte population counts, differences were only found for heterophils and lymphocytes. PMID:26658029

    A female longfin mako shark Isurus paucus (Guitart-Manday, 1966) was found moribund on the Atlantic Ocean beach near Canaveral National Seashore, Florida; the shark died shortly after stranding. Macroscopic lesions included a partially healed bite mark on the left pectoral fin, a clefted snout, pericardial effusion and a pericardial mass surrounding a 12/0 circle fishing hook. The heart, pericardial mass, gills, ovary, oviduct, shell gland, epigonal organ, liver, kidney and intrarenal and interrenal glands were processed for histopathology and examined by brightfield microscopy. Microscopic examination revealed chronic proliferative and pyogranulomatous pericarditis and myocarditis with rhabdomyolysis, fibrosis and thrombosis; scant bacteria and multifocal granular deposits of iron were found intralesionally. In addition, acute, multifocal infarcts within the epigonal organ and gill filaments were found in association with emboli formed by necrocellular material. The ovary had high numbers of atretic follicles, and the liver had diffuse, severe hepatocellular degeneration, multifocal spongiosis and moderate numbers of melanomacrophage cells. This report provides evidence of direct mortality due to systemic lesions associated with retained fishing gear in a prohibited shark species. Due to the large numbers of sharks released from both recreational and commercial fisheries worldwide, impact of delayed post-release mortality on shark populations is an important consideration.

    Gynogenetic diploid was induced in red crucian carp (RCC) ( Carassius auratus Red Variety) eggs using UV-irradiated spermatozoa from blunt snout bream (B) (Megalobrama amblycephala ) or from mirror carp (C) (Cyprinus carpio. L). Spermatozoa were genetically inactivated by an appropriate UV dosage, and then the maternal DNA was duplicated with cold shock at 0-4 ℃. When using the spermatozoa of B, the fertilization rate, hatching rate and survival at first feeding were 52.6 ± 3.0 %, 23.6 ± 4.1 % and 15.7 ± 3.4 %, respectively, and the survival at first feeding was significantly higher than that ( 11.3 ± 2.2 % ) when using the spermatozoa of C (Cyprinus carpio. L). According to the morphological characteristics, the chromosome number and the degree of gonadal development, gynogenetic RCC could be distinguished from the control hybrids of RCC♀ × B ♂ . The individuals with red body color, 100 chromosomes and normal gonadal development were successful gynogenetic RCC, while the individuals with 124 or 148 chromosomes and delayed gonadal development were hybrids of (RCC × B). The triploid hybrids (RCC × B) (2 years old) were sterile, but the tetraploid hybrids (RCC × B) were sexually mature age of two. In the present study, compared to the spermatozoa of C, the advantages of spermatozoa of B as the activation source were that could increase the survival at first feeding of gynogenetic individuals and simplify the confirmation of gynogenetic status, which suggested that the spermof B was an effective activation source for inducing gynogenesis in crucian carp.

  17. Relationship between tornadoes and hook echoes on April 3, 1974

    Science.gov (United States)

    Forbes, G. S.

    1975-01-01

    Radar observations of tornado families occurring on April 3, 1974 are discussed. Of the 93 tornadoes included in the sample, 81% were associated with hook-like echoes with appendages at least 40 deg to the south of the echo movement. At least one tornado was associated with 62% of the hook-like echoes observed. All of the tornadoes with intensities of F 4 and F 5 were produced by hook-like echoes; the mean intensity of all tornadoes associated with this type of echo was F 3, while the mean intensity of the remaining tornadoes was F1. The tornadic hook-like echoes moved to the right of the non-tornadic echoes forming a tornado line in advance of the squall line. Some tornadoes were associated with 'spiral' echoes.

    Hooke's name is familiar to students of mechanics thanks to the law of force that bears his name. Less well-known is the influence his findings had on the founder of mechanics, Isaac Newton. In a lecture given some twenty years ago, W Arnol'd pointed out the outstanding contribution to science made by Hooke, and also noted the controversial issue of the attribution of important discoveries to Newton that were actually inspired by Hooke. It therefore seems ironic that the two most famous force laws, named after Hooke and Newton, are two geometrical aspects of the same law. This relationship, together with other illuminating aspects of Newtonian mechanics, is described in Arnol'd's book and is worth remembering in standard physics courses. In this didactical paper the duality of the two forces is expounded and an account of the more recent contributions to the subject is given.

  17. Abundance and local range of broad-snouted caiman (Caiman latirostris, Alligatoridae in the northwest of Santa Catarina Island

    Directory of Open Access Journals (Sweden)

    Walfrido Moraes Tomás

    2008-12-01

    Full Text Available This is the first report on the distribution and relative abundance of the broad-snouted caiman on Santa Catarina Island. The study estimated the relative abundance of caiman along the rivers at Estação Ecológica de Carijós, in addition to evaluating the occurrence of this species in the entire area of the Ratones River plain on the northwestern portion of the island. The mean relative abundance obtained by nocturnal counts was 0.25 (±0.07 caiman/km surveyed. There was a weak correlation between the number of caimans and the air temperature. Based on interviews with the local community and nocturnal surveys of caimans in rivers and reservoirs surrounding the protected area, we concluded that the range occupied by caimans covered the entire area of the Ratones river plain, inhabiting natural habitats (rivers, mangroves, swamps as well as artificial habitats (reservoirs and water channels. Although this study provides basic information about the broad-snouted caiman population on this part of the island, it is aimed mainly at providing guidance for future research.

  18. Secondary neutron dose measurement for proton eye treatment using an eye snout with a borated neutron absorber

    International Nuclear Information System (INIS)

    We measured and assessed ways to reduce the secondary neutron dose from a system for proton eye treatment. Proton beams of 60.30 MeV were delivered through an eye-treatment snout in passive scattering mode. Allyl diglycol carbonate (CR-39) etch detectors were used to measure the neutron dose in the external field at 0.00, 1.64, and 6.00 cm depths in a water phantom. Secondary neutron doses were measured and compared between those with and without a high-hydrogen–boron-containing block. In addition, the neutron energy and vertices distribution were obtained by using a Geant4 Monte Carlo simulation. The ratio of the maximum neutron dose equivalent to the proton absorbed dose (H(10)/D) at 2.00 cm from the beam field edge was 8.79 ± 1.28 mSv/Gy. The ratio of the neutron dose equivalent to the proton absorbed dose with and without a high hydrogen-boron containing block was 0.63 ± 0.06 to 1.15 ± 0.13 mSv/Gy at 2.00 cm from the edge of the field at depths of 0.00, 1.64, and 6.00 cm. We found that the out-of-field secondary neutron dose in proton eye treatment with an eye snout is relatively small, and it can be further reduced by installing a borated neutron absorbing material

  19. Ecological adaptations of Hypocyrta glabra Hook. flowers

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available The research on the blooming ecology and the flower morphology of Hypocyrta glabra Hook. (Gesneriaceae cultivated in laboratories and outdoors have been carried out. The life span of flowers and morphological changes in successive phases of the blooming period have been observed. The H. glabra flowers are protandrous and the stamens translocate during the flowering process. The macro- and microstructure of calyx, corolla, androecium, gynoecium and nectaries have been analyzed. The size, shape and viability of pollen grains have been designated and their number per stamen head has been calculated. The location of nectaries in H. glabra flowers has suggested that they stem from the 5th stamen during phylogenesis. It has been proved that the nectaries are provided by numerous vascular bundles and that the nectar is secreted by stomata. The stomatal field comprises 2/5 of nectary height and is situated on the abaxial side of the apix part. The average number of stomata is 63.2 per 1 mm2. The average amount of nectar produced by 10 flowers in their fourth day of life reached 223.7 mg. The sugar concentration was 32.7%. Numerous glandular and non-glandular trichomes have been noticed on the surface of calyx, corolla and gynoecium, which indicate the xeromorphic adaptation of the flower. It has been observed that the numbers of glandular and non-glandular trichomes per unit of the external surface of corolla are similar. Outdoors the secretion produced by calyx and corolla glands was willingly collected by wasps. It seems that such features of H. glabra flowers as position, shape and colour of corolla, the abundance of the nectar and pollen produced are connected with their adaptation to pollination by humming-birds in the species natural environment.

  20. Newton–Hooke-type symmetry of anisotropic oscillators

    International Nuclear Information System (INIS)

    Rotation-less Newton–Hooke-type symmetry, found recently in the Hill problem, and instrumental for explaining the center-of-mass decomposition, is generalized to an arbitrary anisotropic oscillator in the plane. Conversely, the latter system is shown, by the orbit method, to be the most general one with such a symmetry. Full Newton–Hooke symmetry is recovered in the isotropic case. Star escape from a galaxy is studied as an application. -- Highlights: ► Rotation-less Newton–Hooke (NH) symmetry is generalized to an arbitrary anisotropic oscillator. ► The orbit method is used to find the most general case for rotation-less NH symmetry. ► The NH symmetry is decomposed into Heisenberg algebras based on chiral decomposition

  1. Hook whistlers observed at low latitude ground station Varanasi

    International Nuclear Information System (INIS)

    Employing the Haselgrove ray tracing equations and a diffusive equilibrium model of the ionosphere, the propagation characteristics of hook whistlers recorded at low-latitude ground station Varanasi (geomag. lat., 1606'N) are discussed. It is shown that the two traces of the hook whistlers are caused by the VLF waves radiated from the return stroke of a lightning discharge which after penetrating the ionosphere at two different entry points, propagated to the opposite hemisphere in the whistler mode and were received at 16 geomagnetic latitude. Further the crossing of ray paths for the same frequency leads to the explanation of the hook whistler. The lower and higher cut-off frequencies are explained in terms of their deviating away from the bunch of the recorded whistler waves and crossing of ray paths for the same frequency. (Auth.)

    Interferon regulatory factors (IRFs) play a key role in mediating the host response against pathogen infection and other important biological processes. This is the first report of an IRF family member in blunt snout bream Megalobrama amblycephala. The complete cDNA of M. amblycephala (Ma) IRF1 gene has 1422 nucleotides (nt.), with an open reading frame of 858 nt, encoding a polypeptide of 285 amino acids. The putative MaIRF1 polypeptide shared significant structural homology with known IRF1 homologs: a conserved IRF domain was found at the N-terminal and an IRF association domain 2 at the C-terminal. Phylogenetic analysis showed that MaIRF1 amino acid sequence clustered with other teleost IRF1s, with a grass carp ortholog exhibiting the highest similarity. MaIRF1 mRNA expression patterns were studied using quantitative real-time PCR in healthy fish tissues and after a challenge with Aeromonas hydrophila bacterium. It was constitutively expressed in all examined tissues: the highest in blood, the lowest in muscle. The expression after A. hydrophila challenge was up-regulated in liver, spleen and kidney, but down-regulated in intestine and gills. At the protein level, similar expression patterns were observed in liver and gills. Patterns differed in intestine (up-regulation), spleen (down-regulation) and kidney (expression mostly unchanged). This study indicates that MaIRF1 gene plays an important role in the blunt snout bream immune system, hence providing an important base for further studies. PMID:27150048

    These remotely sensed, geographically referenced elevation measurements of Lidar-derived topography were produced as a collaborative effort between the U.S. Geological Survey (USGS), Florida Integrated Science Center (FISC), St. Petersburg, FL; the National Park Service (NPS), Northeast Coastal and Barrier Network, Kingston, RI; and the National Aeronautics and Space Administration (NASA), Wallops Flight Facility, VA. This project provides highly detailed and accurate datasets of Gateway National Recreation Area's Sandy Hook Unit in New Jersey, acquired on May 16, 2007. The datasets are made available for use as a management tool to research scientists and natural resource managers. An innovative airborne Lidar instrument originally developed at the NASA Wallops Flight Facility, and known as the Experimental Advanced Airborne Research Lidar (EAARL) was used during data acquisition. The EAARL system is a raster-scanning, waveform-resolving, green-wavelength (532-nanometer) Lidar designed to map near-shore bathymetry, topography, and vegetation structure simultaneously. The EAARL sensor suite includes the raster-scanning, water-penetrating full-waveform adaptive Lidar, a down-looking red-green-blue (RGB) digital camera, a high-resolution multi-spectral color infrared (CIR) camera, two precision dual-frequency kinematic carrier-phase GPS receivers and an integrated miniature digital inertial measurement unit, which provide for submeter georeferencing of each laser sample. The nominal EAARL platform is a twin-engine Cessna 310 aircraft, but the instrument may be deployed on a range of light aircraft. A single pilot, a Lidar operator, and a data analyst constitute the crew for most survey operations. This sensor has the potential to make significant contributions in measuring sub-aerial and submarine coastal topography within cross-environmental surveys. Elevation measurements were collected over the survey area using the EAARL system, and the resulting data were then

  7. BOOK REVIEW: Robert Hooke and the Royal Society

    Brown, Neil

    2000-01-01

    Many physics students only come across Hooke when they learn his law of stretching springs, which is a pity because it is just one of his contributions to progress in science, and a minor one at that. His, Micrographia, the first great book of microscopical observations, arouses admiration to this day. He was also active in horology, astronomy, geology and surveying, and he took part in biological experiments, transfusing blood between animals. Much of his work was done while he was curator of experiments for the Royal Society, in which he was involved almost from its foundation. This was by no means a full-time occupation, however. After the Great Fire of London, Hooke was appointed one of the three surveyors for the rebuilding of the city. One of the others was Christopher Wren, a lifelong friend. In this role Hooke was responsible for the design of several buildings, including the Monument. Nichols writes about all these activities, as well as Hooke's childhood, his education at Westminster School, the University of Oxford when Hooke was an undergraduate, and the founding of the Royal Society. The book draws on research for a master's degree. Turning a dissertation into a popular book is risky. The author has avoided the pitfall of making it too academic, but the result is not satisfying. Nichols seems overawed by Hooke and his work, frequently seeming to credit Hooke with a far-reaching influence that he did not necessarily have. There may be a case for lauding Hooke as the father of English microscopy, the father of English meteorology, and the founder of English geology and earth sciences, but it needs to be made much more critically, even in a popular work. Hooke was full of good ideas, but he rarely continued long enough to put them into practice. There is no doubt that Hooke proposed using a balance wheel and spring to improve the timekeeping of a watch, for example, but he did not have a watch made to his design until after Christiaan Huygens had

  8. Genetic diversity of and differentiation among five populations of blunt snout bream (Megalobrama amblycephala revealed by SRAP markers: implications for conservation and management.

    Directory of Open Access Journals (Sweden)

    Wei Ji

    Full Text Available The blunt snout bream (Megalobrama amblycephala is an important freshwater aquaculture fish throughout China. Because of widespread introductions of this species to many regions, the genetic diversity of wild and natural populations is now threatened. In the present study, SRAP (sequence-related amplified polymorphism markers were used to assess genetic diversity of blunt snout bream. Three natural populations (Liangzi Lake, Poyang Lake and Yuni Lake, one cultured population (Nanxian and one genetic strain ('Pujiang No. 1' of blunt snout bream were screened with 88 SRAP primer combinations, of which 13 primer pairs produced stable and reproducible amplification patterns. In total, 172 bands were produced, of which 132 bands were polymorphic. Nei's gene diversity (h and Shannon's information index (I values provided evidence of differences in genetic diversity among the five populations (Poyang Lake>Liangzi Lake>Nanxian>'Pujiang No. 1'>Yuni Lake. Based on cluster analysis conducted on genetic distance values, the five blunt snout bream populations were divided into three groups, Poyang Lake and Liangzi Lake (natural populations, Nanxian and 'Pujiang No. 1' (cultured population and genetically selected strain, and Yuni Lake (natural population. Significant genetic differentiation was found among the five populations using analysis of molecular variance (AMOVA, with more genetic divergence existing among populations (55.49%, than within populations (44.51%. This molecular marker technique is a simple and efficient method to quantify genetic diversity within and among fish populations, and is employed here to help manage and conserve germplasm variability of blunt snout bream and to support the ongoing selective breeding programme for this fish.

  9. Ring on the hook: placing a ring on a moving and pendulating hook based on visual input

    DEFF Research Database (Denmark)

    2011-01-01

    Purpose – The purpose of this paper is to describe a robot vision system which put rings on hooks that are moving freely on a conveyor belt. The hook can show a significant swinging which can be well approximated by a pendulum movement. The problem is of large relevance for many industrial...... applications and the challenge is to compute a 3D pose that is sufficiently precise to allow for successful placements of the rings. Design/methodology/approach – This requires a fast and precise tracking and a compensation for latencies connected to the processing of visual information as well as the actual...... robot action. Findings – The authors achieve this through a precise pose estimation in a high-resolution stereo setup, as well as a modeling of the hook movement as a combination of a translational and a pendulum movement. Originality/value – The paper shows that under normal conditions close to 100...

  10. Hooking up: gender differences, evolution, and pluralistic ignorance.

    Science.gov (United States)

    Reiber, Chris; Garcia, Justin R

    2010-01-01

    "Hooking-up"--engaging in no-strings-attached sexual behaviors with uncommitted partners--has become a norm on college campuses, and raises the potential for disease, unintended pregnancy, and physical and psychological trauma. The primacy of sex in the evolutionary process suggests that predictions derived from evolutionary theory may be a useful first step toward understanding these contemporary behaviors. This study assessed the hook-up behaviors and attitudes of 507 college students. As predicted by behavioral-evolutionary theory: men were more comfortable than women with all types of sexual behaviors; women correctly attributed higher comfort levels to men, but overestimated men's actual comfort levels; and men correctly attributed lower comfort levels to women, but still overestimated women's actual comfort levels. Both genders attributed higher comfort levels to same-gendered others, reinforcing a pluralistic ignorance effect that might contribute to the high frequency of hook-up behaviors in spite of the low comfort levels reported and suggesting that hooking up may be a modern form of intrasexual competition between females for potential mates.

    A survey was conducted in the equatorial area of Indian Ocean for a better understanding of the dynamics of hook depth distribution of pelagic longline fishery.We determined the relationship between hook depth and vertical shear of current coefficiency,wind speed,hook position code,sine of wind angle,sine of angle of attack and weight of messenger weight.We identified the hook depth models by the analysis of covariance with a general linear model.The results showed that the wind effect on the hook depth can be ignored from October to November in the survey area; the surface current effect on the hook depth can be ignored; the equatorial undercurrent is the key factor for the hook depth in Indian Ocean; and there is a negative correlation between the hook depth and vertical shear of current and angle of attack.It was also found that the deeper the hook was set,the higher hook depth shoaling was.The proposed model improves the accuracy of the prediction of hook depth,which can be used to estimate the vertical distribution of pelagic fish in water column.

    Doublesex and Mab3 related transcription factor (DMRT), characterized by a conserved DM domain, function as sex-related transcription factors and also play critical roles in ontogenesis. In this study, 4 Dmrt genes in the blunt snout bream, Megalobrama amblycephala, were identified, characterized and their mRNA expression in different adult organs, during embryogenesis and gonadal development in larvae were determined by quantitative real time PCR. There are 4 Dmrt1 isoforms in the M. amblycephala genome, which were expressed highly in the testis and weakly in the ovary. The complete cDNAs of the M. amblycephala Dmrt2a, Dmrt2b and Dmrt3 were predicted to encode 510, 328 and 449 amino acids, respectively. The M. amblycephala Dmrt2a mRNA peaked at 11hpf (hour post fertilizing) during early embryonic stages, while Dmrt2b was highly expressed during late embryonic stages. Both the M. amblycephala Dmrt2a and Dmrt2b were expressed highly in the gill and exhibited a sexually dimorphic expression pattern. The M. amblycephala Dmrt3 was expressed highly in the gill, muscle and brain, at 40dph (day post hatching) during early development and at stage V in the testis during gonadal development. All fish Dmrts except Dmrt5 were found in the M. amblycephala genome. The observed expression patterns of these Dmrts in developing embryos and larvae, as well as different adult organs indicate conserved sexual or extragonadal functions of the Dmrts through evolution.

    Full Text Available Blunt snout bream (Megalobrama amblycephala is an important fish species for its delicacy and high economic value in China. Codon usage analysis could be helpful to understand its codon biology, mRNA translation and vertebrate evolution. Based on RNA-Seq data for M. amblycephala, high-frequency codons (CUG, AGA, GUG, CAG and GAG, as well as low-frequency ones (NUA and NCG codons were identified. A total of 724 high-frequency codon pairs were observed. Meanwhile, 14 preferred and 199 avoided neighboring codon pairs were also identified, but bias was almost not shown with one or more intervening codons inserted between the same pairs. Codon usage bias in the regions close to start and stop codons indicated apparent heterogeneity, which even occurs in the flanking nucleotide sequence. Codon usage bias (RSCU and SCUO was related to GC3 (GC content of 3rd nucleotide in codon bias. Six GO (Gene ontology categories and the number of methylation targets were influenced by GC3. Codon usage patterns comparison among 23 vertebrates showed species specificities by using GC contents, codon usage and codon context analysis. This work provided new insights into fish biology and new information for breeding projects.

  1. Dynamical realizations of l-conformal Newton–Hooke group

    International Nuclear Information System (INIS)

    The method of nonlinear realizations and the technique previously developed in [A. Galajinsky, I. Masterov, Nucl. Phys. B 866 (2013) 212, (arXiv:1208.1403)] are used to construct a dynamical system without higher derivative terms, which holds invariant under the l-conformal Newton–Hooke group. A configuration space of the model involves coordinates, which parametrize a particle moving in d spatial dimensions and a conformal mode, which gives rise to an effective external field. The dynamical system describes a generalized multi-dimensional oscillator, which undergoes accelerated/decelerated motion in an ellipse in accord with evolution of the conformal mode. Higher derivative formulations are discussed as well. It is demonstrated that the multi-dimensional Pais–Uhlenbeck oscillator enjoys the l=3/2 -conformal Newton–Hooke symmetry for a particular choice of its frequencies

    Full Text Available Myth of a couple who escape death in a chance encounter with the psychopath with a hook instead of a hand, is one of the ten classic urban legends that have been brought to public attention by folklorists during the sixth and seventh decade of the twentieth century. Eminent Anglo-American folklorists dedicated entire papers, or significant portion in their works to this tale, as a contribution to the study of urban legends as a folk genre. In this essay, the legend of the hook is closely linked with the boyfriend's' death legend, its hermetic interpretation, and contextualization in the social reality of sexual relations at the time in which it occurs.

    We provide an algebraic procedure to find the eigenstates of two-charged particles in an oscillator potential, known as {\\it{Hooke's}} atom. For the planar Hooke's atom, the exact eigenstates and single particle densities for arbitrary azimuthal quantum number, are obtained analytically. Information entropies associated with the wave functions for the relative motion are then studied systematically, since the same incorporates the effect of the Coulomb interaction. The {\\it{quantum pottery}} of the information entropy density reveals a number of intricate structures, which differ significantly for the attractive and repulsive cases. We indicate the procedure to obtain the approximate eigen states. Making use of the relationship of this dynamical system with the quasi-exactly solvable systems, one can also develop a suitable perturbation theory, involving the Coulomb coupling $Z$, for the approximate wave functions.

    Full Text Available High level of β - hCG is characteristics of Molar Pregnancy. Molar pregnancy with false negative urine hCG, which is a rarity, is called “HOOK EFFECT”. Here I am going to report a case of 28 weeks size Molar pregnancy, which was misdiagnosed as large fibroid with mult iple cystic degenerative area by both obstetricians and radiologist. This happened due to false negative urine β - hCG test. So to avoid this, clinicians should always keep in their mind, rare possibility of HOOK EFFECT due to very high level of serum β - hCG and in a case of high degree of suspicion, test should be repeated after dilution of sample.

    Full Text Available The aim of the study was to evaluate the influence of different temperature control systems on the voluntary feed intake (VFI, percentage of weight loss (PWL and performance of lactating sows as well as on the weight of their piglets. Two systems were used: traditional temperature control system (TTCS with curtain management and an evaporative snout cooling system (ESCS. The study was performed during the summer of 2011. After farrowing and at the weaning, 241 sows were weighed to evaluate the PWL during lactation. TTCS sows lost more weight (5.3±0.9%; P<0.05 than ESCS sows (2.2±0.9%. VFI was measured at intervals of four days in 32 primiparous and 39 multiparous sows. ESCS sows had higher VFI (5.8±0.2kg day-1; P<0.05 than TTCS sows (4.8±0.2kg day-1. Primiparous sows (4.4±0.2kg day-1 had a lower VFI than multiparous sows (6.3±0.2kg day-1, P<0.05 regardless of the temperature control system. Primiparous sows in the TTCS (10.9±1.3 days had a longer weaning-to-oestrus interval than primiparous sows in the ESCS (7.0±1.2 days, P<0.05. Subsequent litter size tended to be higher (P=0.095 in ESCS than in TTCS (12.0±0.5 and 10.9±0.6 piglets born, respectively. Litters housed in ESCS were heavier (65.3±1.4kg; P<0.05 at weaning than litters in TTCS (60.7±1.4kg. The results suggest that in general sows and piglets housed in the ESCS have better performance than sows and piglets housed in TTCS.

    Very often in Electrical Bioimpedance (EBI) spectroscopy measurements the presence of stray capacitances creates a measurement artefact commonly known as Hook Effect . Such an artefact creates a hook-alike deviation of the EBI data noticeable when representing the measurement on the impedance plane. Such Hook Effect is noticeable at high frequencies but it also causes a data deviation at lower measurement frequencies. In order to perform any accurate analysis of the EBI spectroscopy data, the...

    Nucleus extraction in manual sutureless extracapsular cataract extraction (ECCE) using the 2-hook technique is described. After capsulorhexis and hydrodissection are performed, the nucleus is moved into the anterior chamber and extracted by pulling with a Sinskey hook and pressuring the scleral bed with a Kuglen hook. In a series of 1320 eyes, 85% achieved a corrected visual acuity of 5/10 or better postoperatively. Complications were posterior capsule rupture, vitreous loss, and transient corneal edema. Manual sutureless ECCE using the 2-hook technique is safe and efficient and does not require expensive instrumentation. PMID:23522582

  13. Robert Hooke: early respiratory physiologist, polymath, and mechanical genius.

    Science.gov (United States)

    West, John B

    2014-07-01

    Robert Hooke (1635-1703) was a polymath who made important contributions to respiratory physiology and many other scientific areas. With Robert Boyle, he constructed the first air pump that allowed measurements on small animals at a reduced atmospheric pressure, and this started the discipline of high-altitude physiology. He also built the first human low-pressure chamber and described his experiences when the pressure was reduced to the equivalent of an altitude of ∼2,400 m. Using artificial ventilation in an animal preparation, he demonstrated that movement of the lung was not essential for life. His book Micrographia describing early studies with a microscope remains a classic. He produced an exquisite drawing of the head of a fly, showing the elaborate compound eye. There is also a detailed drawing of a flea, and Hooke noted how the long, many-jointed legs enable the insect to jump so high. For 40 years, he was the curator of experiments for the newly founded Royal Society in London and contributed greatly to its intellectual ferment. His mechanical inventions covered an enormous range, including the watch spring, the wheel barometer, and the universal joint. Following the Great Fire of London in 1666, he designed many of the new buildings in conjunction with Christopher Wren. Unfortunately, Hooke had an abrasive personality, which was partly responsible for a lack of recognition of his work for many years. However, during the last 25 years, there has been renewed interest, and he is now recognized as a brilliant scientist and innovator. PMID:24985326

  14. An experimental 'Life' for an experimental life: Richard Waller's biography of Robert Hooke (1705).

    Moxham, Noah

    2016-03-01

    Richard Waller's 'Life of Dr Robert Hooke', prefixed to his edition of Hooke's Posthumous Works (1705), is an important source for the life of one of the most eminent members of the early Royal Society. It also has the distinction of being one of the earliest biographies of a man of science to be published in English. I argue that it is in fact the first biography to embrace the subject's natural-philosophical work as the centre of his life, and I investigate Waller's reasons for adopting this strategy and his struggle with the problem of how to represent an early experimental philosopher in print. I suggest that Waller eschews the 'Christian philosopher' tradition of contemporary biography - partly because of the unusually diverse and fragmentary nature of Hooke's intellectual output - and draws instead upon the structure of the Royal Society's archive as a means of organizing and understanding Hooke's life. The most quoted phrase from Waller's biography is that Hooke became 'to a crime close and reserved' in later life; this essay argues that Waller's biographical sketch was fashioned in order to undo the effects of that reserve. In modelling his approach very closely on the structure of the society's records he was principally concerned with making Hooke's work and biography accessible, intelligible and useful to the fellowship in a context familiar to them, a context which had provided the institutional framework for most of Hooke's adult life. I argue that Waller's 'Life' was also intended to make the largest claims for Hooke's intellectual standing that the author dared in the context of the enmity between Hooke and Isaac Newton once the latter became president of the Royal Society. However, I also adduce fresh manuscript evidence that Waller actually compiled, but did not publish, a defence of Hooke's claim to have discovered the inverse square law of gravity, allowing us to glimpse a much more assertive biography of Hooke than the published version.

It is assumed that the fracture process is the pull-off of a cone shaped concrete part, simplifying the problem by assuming pure rigid body motions...... allowing elastic deformations only in a layer between the pull-out cone and the concrete base. The derived model is in good agreement with experimental results, it predicts size effects and the model parameters found by calibration of the model on experimental data are in good agreement with what should be...

    2015-04-01

    Engaging high school students in the geosciences without providing them with opportunities to directly explore, understand, and question the natural world is like trying to catch a fish without a hook. How can educators hope to inspire youth to pursue a career in the geosciences when the subject is first introduced to teenagers within the confines of a classroom? Regardless of the content and activities employed by the teacher, the synthetic classroom setting is unable to recreate the organic richness of an authentic outdoor learning environment. A new course offering at Rutland High School in Rutland, Vermont, USA shifts away from the traditional classroom based pedagogy by focusing the learning on exploring the temporal changes occurring in the region's geologic features. Numerous visits to local quarries, outcrops, overlooks, and universities guide the course curriculum. Students use their new understandings and personal observations to complete a culminating independent investigation. This alternate learning model is made possible through collaboration with local universities, businesses, and government agencies. If the geosciences is to remain competitive in the recruitment of exemplary STEM candidates, than the focus of high school earth science programs must be considered. This course offers one alternative to improve engagement and understanding of the geoscience standards. While not the only option, it offers one possibility for hooking students on geosciences.

  3. The Hook: Getting your grounded theory research published

    Directory of Open Access Journals (Sweden)

    Phyllis Noerager Stern, DNS, LLD (hon., FAAN

    2009-01-01

    Full Text Available I learned about the hook as a fledgling writer back in the late 70’s, and early 80s. I wrote about stepfamilies when almost nobody else did (Stern, 1978, 1982a, 1982b. My big break came when I published an English-language version on how to do grounded theory. In my field, nursing, grounded theory was the buzz word of the day, but few nurses had a sociological background, and thus the vocabulary to be able to understand the Glaser and Straus description (Stern, 1980. That article kick started my career as a writer and researcher. There was a time when it was required reading for graduate students in nursing around the world. Twenty-nine years after its publication, I got a request for a reprint from a doctoral student in New Zealand. What the hook consists of then is timing, a subject that has impact, and a title that sparks the interest of a potential reader. A classic example of all three is The Discovery of Grounded Theory (Glaser and Straus, 1967, a then new approach to sociological research. Sociologists were interested, but as the authors were based at the University of California, San Francisco School of Nursing, they had an eager audience in the nursing community who were looking for a research method to formalize what they did as nurses.

    2016-01-01

    Purpose. To evaluate whether subacromial osteolysis, one of the major complications of the clavicle hook plate procedure, affects shoulder function. Methods. We had performed a retrospective study of 72 patients diagnosed with a Neer II lateral clavicle fracture or Degree-III acromioclavicular joint dislocation in our hospital from July 2012 to December 2013. All these patients had undergone surgery with clavicle hook plate and were divided into two groups based on the occurrence of subacromial osteolysis. By using the Constant-Murley at the first follow-up visit after plates removal, we evaluated patients' shoulder function to judge if it has been affected by subacromial osteolysis. Results. We have analyzed clinical data for these 72 patients, which shows that there is no significant difference between group A (39 patients) and group B (33 patients) in age, gender, injury types or side, and shoulder function (the Constant-Murley scores are 93.38 ± 3.56 versus 94.24 ± 3.60, P > 0.05). Conclusion. The occurrence of subacromial osteolysis is not rare, and also it does not significantly affect shoulder function. PMID:27034937

  7. A novel approach for removing the hook effect artefact from Electrical Bioimpedance spectroscopy measurements

    Science.gov (United States)

    Buendia, R.; Seoane, F.; Gil-Pita, R.

    Very often in Electrical Bioimpedance (EBI) spectroscopy measurements the presence of stray capacitances creates a measurement artefact commonly known as Hook Effect. Such an artefact creates a hook-alike deviation of the EBI data noticeable when representing the measurement on the impedance plane. Such Hook Effect is noticeable at high frequencies but it also causes a data deviation at lower measurement frequencies. In order to perform any accurate analysis of the EBI spectroscopy data, the influence of the Hook Effect must be removed. An established method to compensate the hook effect is the well known Td compensation, which consists on multiplying the obtained spectrum, Zmeas(ω) by a complex exponential in the form of exp[jωTd]. Such a method cannot correct entirely the Hook Effect since the hook-alike deviation occurs a broad frequency range in both magnitude and phase of the measured impedance, and by using a scalar value for Td. First a scalar only modifies the phase of the measured impedance and second, a single value can truly corrects the Hook Effect only at a single frequency. In addition, the process to select a value for the scalar Td by an iterative process with the aim to obtain the best Cole fitting lacks solid scientific grounds. In this work the Td compensation method is revisited and a modified approach for correcting the Hook Effect including a novel method for selecting the correcting values is proposed. The initial validation results confirm that the proposed method entirely corrects the Hook Effect at all frequencies.

    Competition between spermatozoa of rival males to gain fertilizations has led to a wide array of modifications in sperm structure and function. Sperm cells of most muroid rodents have hook-shaped extensions in the apical-ventral tip of the head, but the function of this structure is largely unknown. These 'hooks' may facilitate aggregation of spermatozoa in so-called 'trains', as an adaptation to sperm competition, because sperm in trains may swim faster than free-swimming cells. However, there is controversy regarding the role of the hook in train formation, and in relation to whether it is selected by sperm competition. We examined spermatozoa from muroid rodents with varying levels of sperm competition to assess whether (i) sperm aggregates are common in these taxa, (ii) presence of a hook relates to the formation of sperm aggregations, and (iii) formation of sperm aggregations is explained by sperm competition. Our analyses in 25 muroid species revealed that > 92% of spermatozoa swim individually in all species, with the exception of the wood mouse, Apodemus sylvaticus, which has ~50% spermatozoa swimming freely. Species with hooked spermatozoa had higher sperm competition levels and longer sperm than species whose sperm lack a hook. Neither the presence of hook nor sperm competition levels were related to the percentage of sperm in aggregations. Thus, (i) sperm aggregates in muroid rodents are an exceptional trait found only in a few species, (ii) evolution of the sperm hook is associated to sperm competition levels, but (iii) the hook is unlikely to be related to the formation of sperm aggregates. The evolutionary significance of the sperm head hook thus remains elusive, and future studies should examine potential roles of this pervasive structure in sperm's hydrodynamic efficiency and sperm-female tract interactions.

    A new marine-fish cell line, designated GPS, was established from the snout tissue of golden pompano Trachinotus ovatus. GPS cells multiplied well in Leibovitz's L-15 containing 10% foetal bovine serum (FBS) at 28° C and the cells have been subcultured for >60 passages. Polymerase chain reaction (PCR) amplification of 16S ribosomal (r)RNA confirmed the origin of this cell line from T. ovatus. Chromosome analysis showed that GPS cells exhibited chromosomal aneuploidy with a modal chromosome number of 54. Bright green fluorescence signal was observed in enhanced green fluorescent protein (EGFP)-N3 transfected cells, indicating that GPS cells could be used to investigate gene functions in vitro. The GPS cells were highly susceptible to Singapore grouper iridovirus (SGIV), which was demonstrated by the presence of severe cytopathic effect (CPE) and increased viral titres. Real-time quantitative PCR and Western blot analysis showed that the viral gene transcription and protein synthesis occurred during SGIV infection in GPS cells. Thus, this study described the characteristic of a new cell line from the snout tissue of T. ovatus that could be used as a tool for propagation of iridovirus and genetic manipulation to investigate host-pathogen interactions.

    2012-06-01

    Full Text Available Quantitative data on the mechanical performance of upper-limb prostheses are very important in prostheses development and selection. The primary goal of this study was to objectively evaluate the mechanical performance of adult-size voluntary opening (VO prosthetic terminal devices and select the best tested device. A second goal was to see whether VO devices have improved in the last two decades. Nine devices (four hooks and five hands were quantitatively tested (Hosmer model 5XA hook, Hosmer Sierra 2 Load VO hook, RSL Steeper Carbon Gripper, Otto Bock model 10A60 hook, Becker Imperial hand, Hosmer Sierra VO hand, Hosmer Soft VO hand, RSL Steeper VO hand, Otto Bock VO hand. We measured the pinch forces, activation forces, cable displacements, mass, and opening span and calculated the work and hysteresis. We compared the results with data from 1987. Hooks required lower activation forces and delivered higher pinch forces than hands. The activation forces of several devices were very high. The pinch forces of all tested hands were too low. The Hosmer model 5XA hook with three bands was the best tested hook. The Hosmer Sierra VO hand was the best tested hand. We found no improvements in VO devices compared with the data from 1987.

    The aim of this study was to develop an efficient cryopreservation protocol for the geophyte giant snowdrop (Galanthus elwesii Hook.) that guarantees a high rate of survival and plant regeneration after cryopreservation. The excised apical meristems were obtained from cultures of in vitro grown bulb scales. Using a vitrification procedure and optimizing the duration of the exposure to the loading solution (LS), meristem post-rewarm survival rates higher than 90 percent were achieved. Also regrowth percentages were very high, ranging from 87 to 91 percent. After optimizing the time of exposure to the plant vitrification solution (PVS2), the survival rate was between 83 and 97 percent. During post-rewarm regeneration, good growth recovery was as high as 76 percent; however, hyperhydration and callusing were also observed. The results demonstrate that cryopreservation of Galanthus elwesii germplasm seems to be feasible. PMID:23435704

    2014-02-01

    Full Text Available The oil secreting glands of Hiptage sericea Hook. consist of three regions: epithelial, sub-epithelial and sub-glandular. In early stages, the oil secreting cells are characterized by the presence of plastids with starch grains and electron translucent vesicles, mitochondria, rER, polysomes, small vacuoles, numerous lipid bodies and well-defined nucleus with nucleolus. Later, the accumulation of plastoglobuli and inclusion bodies occur in the matrix of the plastid. Tubular, smooth endoplasmic reticulum begins to appear in the cytoplasm. With the onset of secretion, the osmiophilic contents of plastids which appear as electron dense, round droplets move-into cytoplasm and often occur in the region of the plasmalemma invaginations. However, in matured glands the lipid bodies disappear from the cytoplasm. The size of the vacuoles increases and are filled with electron opaque substance. Similar substances are also found in the sub-cuticular spaces as well as outside the cuticle.

    2016-01-01

    Full Text Available Genomic resources for conventional breeding programs are extremely limited for coniferous trees, and existing simple sequence repeat markers are usually identified through the laborious process of hybridization screening. Therefore, this study aimed to identify gene-based microsatellites in the Chinese fir, Cunninghamia lanceolata (Lamb. Hook by screening transcript data. We identified 5200 microsatellites. Trinucleotide motifs were most common (47.94% and were followed by tetranucleotide motifs (24.92%. The AG/CT motif (43.93% was the most abundant dinucleotide repeat, whereas AAG/CTT (25.07% was the most common trinucleotide repeat. A total of 411 microsatellite primer pairs were designed and 97 polymorphic loci were identified by 8 genotypes. The number of alleles per locus (Na in these polymorphic loci ranged from 2 to 5 (mean, 2.640, the Ho values were 0.000-1.000 (mean, 0.479, and the HE values were 0.125-0.775 (mean, 0.462. The polymorphic information content (PIC values were 0.110-0.715 (mean, 0.383. Seventy-two of the 97 polymorphic markers (74.23% were present within genes with predicted functions. In addition, in genetic diversity and segregation analyses of 16 genotypes, only 5.88% of the polymorphic loci displayed segregation distortion at the p<0.05 level. Transferable amplification of a randomly selected set of 30 genic microsatellites showed that transferability decreased with increasing evolutionary distance between C. lanceolata and target conifers. Thus, these 97 genic markers will be useful for genetic diversity analysis, germplasm characterization, genome mapping and marker-assisted breeding in C. lanceolata, and evolutionary genetic analysis in Taxodiaceae.

  8. Case report 464: Bilateral congenital absence of the hook of the hamate

    International Nuclear Information System (INIS)

    A 28-year-old man presented after an injury in a fight, showed absence of the hook or hamulus of the hamate bone in the symptomatic left wrist. The asymptomatic right wrist showed a similar change, indicating the diagnosis of congenital absence of the hook of the hamate - an abnormality apparently not previously described in the literature. The anatomical and clinical implications, both potential and real, of fractures or dislocations of the wrist, are discussed briefly. It is stressed by the authors that the potential for a misdiagnosis, particularly in a case of trauma to the wrist, certainly exists in instances where an absent or hypoplastic hook of the hamate is present. It is also stressed that even though a hook of the hamate is not delineated radiologically, it may be present in its cartilaginous form. Under such circumstances, imaging with magnetic resonance might be helpful. (orig.)

    2016-04-01

    Full Text Available OBJECTIVE To evaluate clinical outcome of clavicular hook plate and autograft technique in the surgical treatment of Rockwood Grade-III acromioclavicular joint dislocation. METHODS Fifteen patients were operated using standard clavicular hook plate and another fifteen patients were operated using autograft technique. After a minimum follow-up of one year, clinical assessment was done using Constant-Murley Score. Statistical evaluation was done using SPSS ver. 21.0. RESULTS Mean age group was 31.44±7.8 years. Average constant shoulder score for the hook plate group was 81.3 (Range 74–89 and that for autograft technique group was 91.7 (Range 88–97. CONCLUSION Autograft technique was found to be superior in terms of functional outcome when compared to clavicular hook plate. Such superiority can be attributed to the biologic nature of coracoclavicular ligament reconstruction in the autograft technique.

  9. Development and impact of hooks of high droplet concentration on remote southeast Pacific stratocumulus

    Directory of Open Access Journals (Sweden)

    R. C. George

    2013-07-01

    Full Text Available Over the southeastern Pacific (SEP, droplet concentration (Nd in the typically unpolluted marine stratocumulus west of 80° W (> 1000 km offshore is periodically strongly enhanced in zonally elongated "hook"-shaped features that increase albedo. Here, we examine three hook events using the chemistry version of the Weather Research and Forecasting model (WRF-Chem with 14 km horizontal resolution, satellite data, and aircraft data from the VAMOS Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx. A particularly strong hook yields insights into the development, decay, and radiative impact of these features. Hook development occurs with Nd increasing to polluted levels over the remote ocean primarily due to entrainment of cloud condensation nuclei (CCN from the lower free troposphere (FT. The feature advects northwestward until the FT CCN source is depleted, after which Nd decreases over a few days due to precipitation and dilution. The model suggests that the FT CCN source supplying the hook consists of high concentrations of small accumulation-mode aerosols that contribute a relatively small amount of aerosol mass to the MBL, in agreement with near-coast VOCALS measurements of polluted layers in the FT. The aerosol particles in this hook originate mainly from a pulse of offshore flow that transports Santiago-region (33–35° S emissions to the remote marine FT. To provide pollution CCN that can sustain hooks, the FT transport of pollution plumes to the remote ocean requires strong, deep offshore flow. Such flow is favored by a trough approaching the South American coast and a southeastward shift of the climatological subtropical high-pressure system. The model simulations show precipitation suppression in the hook and a corresponding increase in liquid water path (LWP compared with a simulation without anthropogenic sources. LWP also increases as the hook evolves over time due to increasing stability and decreasing subsidence. WRF

    2009-01-01

    The full-length mRNA of the high mobility group protein 1 coding gene (HMG1) was obtained by RACE-PCR from red crucian carp (Carassius auratus red var.),blunt snout bream (Megalobrama amblycephala),and their triploid and tetraploid progeny.The sequence contained an open reading frame of 579 nucleotides coding for 193 amino acids.The nucleotide identity of HMG1 was higher between the tetraploid hybrid and the maternal red crucian carp (99%) than between the tetraploid hybrid and the paternal blunt snout bream (97%).The nucleotide identity between the triploid hybrids and each parent (95%) was lower than that between the parents (98%).The protein identity between the tetraploid hybrid and each parent (100%) was higher than that between the triploid hybrid and each parent (97%).Our results suggest that interspecific hybridization generates a shock to the HMG1 gene in triploid hybrids,causing divergence of nucleotides.The HMG1 protein of the tetraploid hybrids was consistent with that of its parents,which reduced the barrier of cross incompatibility between alleles,providing the basis for the bisexual fertile tetraploid hybrids forming a new polyploid species in nature.The secondary and tertiary structures of the HMG1 protein contain eight helices,three switches,two DNA-binding domains in the N-terminus,and a long acidic tail in the C-terminus.Together,these data suggest that the HMG1 protein plays a role of protein-DNA interactions,facilitating various DNA-dependent activities in the nucleus.We also investigated the phylogeny of fish,amphibian,reptilian,bird,and mammalian HMG1 proteins.Our results suggest that HMG1 is an ancestral protein that has been highly conserved.These data provide clues as to how interspecific hybridization may form polyploid hybrids.

    The Pan-African Hook batholith is emplaced N of the Mwembeshi dislocation, a regional scale structure at the contact between Zambezi Belt and Lufilian Arc in Central Zambia. Exposed over 12000 km2 the batholith is composed mainly of fine-grained and coarse-grained porphyritic granites and leucogranites affected by solid-state deformation along high-strain zones. Two main zones of deformation were investigated - the Itezhi-Tezhi Zone (ITZ) in the SW part of the batholith and the Nalusanga Zone (NZ) to the NE. The 2.5 km wide, N-S trending, subvertical ITZ is a medium-grade, pure shear dominated structure, reflecting probably regional scale E-W shortening. In the central part of the zone, augen-gneiss textures developed. Mineral lineations plunging ~40° S are recorded occasionally. The deformed feldspar porphyroclasts show symmetrical tails and rarely sinistral stair-stepping. In the SE part of the Hook batholith the continuation of the ITZ trends E-W. This orientation can be explained by rotation of the original ITZ trend by N-S shortening that also has been recorded in the siliciclastic metasediments S of the contact. S dipping, up to 15 cm wide thrust zones observed in the ITZ area were probably formed during this tectonic event. The 3 km wide NZ is a subvertical to steeply SSW dipping structure, parallel to the NE contact of the batholith, with well-developed foliation and mineral stretching lineations. Field and microstructural analyses defined the NZ as a medium-grade, non-coaxial, sinistral strike-slip shear zone. The transition from weak foliated granite to S-C mylonites and ultramylonites was observed. The sinistral shearing is consistent with E-W shortening in agreement with the tectonic framework of the ITZ. The low grade metasediments to the E of the granite are folded in N to NNW trending structures also implying E-W shortening. Temperature conditions during the deformation in ITZ and NZ inferred from microstructural analyses are about 500°-550°C. The

    International Nuclear Information System (INIS)

    Stress fractures of the hook of the hamate are related to sports that use devices such as golf clubs, rackets and baseball bats. Because usually there is no history of obvious trauma, the diagnosis necessitates better knowledge of the lesion and high index of suspicion. The authors report a case of stress fracture of the hook of the hamate in a golf player with diagnosis and follow-up done with magnetic resonance and multislice computer tomography. (author)

    Background Sperm design varies enormously across species and sperm competition is thought to be a major factor influencing this variation. However, the functional significance of many sperm traits is still poorly understood. The sperm of most murid rodents are characterised by an apical hook of the sperm head that varies markedly in extent across species. In the European woodmouse Apodemus sylvaticus (Muridae), the highly reflected apical hook of sperm is used to form sperm groups, or “tr...

    In the traditional port, disengaging hook system adopts a three-phase power frequency power to drive a three-phase asynchronous motor. The operation is simple and the maintenance is convenient. However, it still keeps the speed of mooring lines constant. Under the light-load condition, the work efficiency could be affected because of the low speed. To solve this problem, we start the research in speed control of disengaging hook. By using variable frequency control technology to transform the...

  19. Development and impact of hooks of large droplet concentration on remote southeast Pacific stratocumulus

    Full Text Available Over the southeastern Pacific (SEP, droplet concentration (Nd in the typically unpolluted marine stratocumulus west of 80° W (> 1000 km offshore is periodically strongly enhanced in zonally-elongated "hook"-shaped arcs that increase albedo. Here, we examine three hook events using the chemistry version of the Weather Research and Forecasting model (WRF-Chem with 14 km horizontal resolution, satellite data and aircraft data from the VAMOS Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx. A particularly strong hook yields insights to the development, decay, and radiative impact of these features. Hook development occurs with Nd increasing to polluted levels over the remote ocean primarily due to entrainment of cloud condensation nuclei (CCN from the free troposphere (FT. The feature advects northwestward until the FT CCN source is depleted, after which Nd decreases over a few days due to precipitation and dilution. The model suggests that the FT CCN source supplying the hook consists of high concentrations of small accumulation mode aerosols that contribute a relatively small amount of aerosol mass to the MBL. The aerosol particles originate mainly from a pulse of offshore flow that transports Santiago region (33–35° S emissions to the marine FT.

    To provide a sustained hook CCN source, the FT transport of pollution plumes to the remote ocean requires strong, deep offshore flow. Such flow is favored by a trough approaching the South American coast and a southeastward shift of the climatological subtropical high pressure system. The model simulations show precipitation suppression in the hook and a corresponding increase in liquid water path (LWP compared with a simulation without anthropogenic sources. LWP also increases in time as the hook evolves due to increasing stability and decreasing subsidence. WRF-Chem suggests that DMS significantly influences the aerosol

    We describe the conclusions of a technology and communities survey supported by concurrent and follow-on proof-of-concept prototyping to evaluate feasibility of defining a durable, versatile, reliable, visible software interface to support strategic modularization of test software development. The objective is that test sets and support software with diverse origins, ages, and abilities can be reliably integrated into test configurations that assemble and tear down and reassemble with scalable complexity in order to conduct both parametric tests and monitored trial runs. The resulting approach is based on integration of three recognized technologies that are currently gaining acceptance within the test industry and when combined provide a simple, open and scalable test orchestration architecture that addresses the objectives of the Automation Hooks task. The technologies are automated discovery using multicast DNS Zero Configuration Networking (zeroconf), commanding and data retrieval using resource-oriented Restful Web Services, and XML data transfer formats based on Automatic Test Markup Language (ATML). This open-source standards-based approach provides direct integration with existing commercial off-the-shelf (COTS) analysis software tools.

    2016-01-01

    We studied the magnetic topology of active region 12158 on 2014 September 10 and compared it with the observations before and early in the flare which begins at 17:21 UT (SOL2014-09-10T17:45:00). Our results show that the sigmoidal structure and flare ribbons of this active region observed by SDO/AIA can be well reproduced from a Grad-Rubin non linear force free field extrapolation method. Various inverse-S and -J shaped magnetic field lines, that surround a coronal flux rope, coincide with the sigmoid as observed in different extreme ultraviolet wavelengths, including its multi-threaded curved ends. Also, the observed distribution of surface currents in the magnetic polarity where it was not prescribed is well reproduced. This validates our numerical implementation and set-up of the Grad-Rubin method. The modeled double inverse-J shaped Quasi-Separatrix Layer (QSL) footprints match the observed flare ribbons during the rising phase of the flare, including their hooked parts.

    Full Text Available Abstract Background Hamate hook fracture is a common fracture in golfers and others who play sports that involve rackets or sticks such as tennis or hockey. This patient had a previous hamate fracture in the opposing wrist along with potential features of hamate bipartite. Case presentation A 19 year old male presented with a complaint of right wrist pain on the ulnar side of the wrist with no apparent mechanism of injury. The pain came on gradually one week before being seen in the office and he reported no prior care for the complaint. His history includes traumatic left hamate hook fracture with surgical excision. Conclusion The patient was found to have marked tenderness over the hamate and with a prior fracture to the other wrist, computed tomography of the wrist was ordered revealing a fracture to the hamate hook in the right wrist. He was referred for surgical evaluation and the hook of the hamate was excised. Post-surgically, the patient was able to return to normal activity within eight weeks. This case is indicative of fracture rather than hamate bipartite. This fracture should be considered in a case of ulnar sided wrist pain where marked tenderness is noted over the hamate, especially after participation in club or racket sports.

    Controversy exists with the use of the acromioclavicular hook plate for the treatment of lateral-third clavicle fractures (Neer type II). This is thought to stem from problems associated with the hook plate causing impingement symptoms, which can cause long-term limitation of movement and pain. Our aim was to evaluate the functional outcomes of patients with lateral-third clavicle fractures treated with the hook plate.

    Hooking up is a normative behavior among college students that is associated with a range of positive and negative consequences. While previous research has primarily focused on women's negative experiences of hooking up, the current study explored the relationships among hooking up behaviors, psychological distress, and a broad range of negative effects of hooking up in both male and female college students. Using a multisite sample of college students, we developed the 14-item Negative Impact of Hookups Inventory (NIHI) to assess negative health outcomes, emotional responses, and social consequences associated with hooking up. Unprotected sex and having more hookup partners were associated with greater negative experiences of hooking up. Contrary to expectations, there were no gender differences in the total number of negative hookup effects, although men reported more frequent hookups. In addition, negative impacts of hooking up were positively associated with psychological distress regardless of gender. The NIHI may offer a useful tool to assess the negative impacts of hooking up. Understanding students' hookup experiences is an important step toward developing targeted health interventions related to hooking up behavior in young adult populations. PMID:26445346

    2016-01-01

    This work addresses the problem of self-excited vibration, which degrades the stability of the levitation control, decreases the ride comfort, and restricts the construction cost of maglev system. Firstly, a minimum model containing a flexible bridge and a single levitation unit is presented. Based on the simplified model, the principle underlying the self-excited vibration is explored. After investigations about the energy transmission between the levitation system and bridge, it is concluded that the increment of modal damping can dissipate the accumulated energy by the bridge and the self-excited vibration may be avoided. To enlarge the equivalent modal damping of bridge, the sky-hooked damper is adopted. Furthermore, to avoid the hardware addition of real sky-hooked damper, considering the fact that the electromagnet itself is an excellent actuator that is capable of providing sufficiently fast and large force acting on the bridge to emulate the influence of the real sky-hooked damper, the technique of the virtual sky-hooked damper is proposed. The principle underlying the virtual sky-hooked damper by electromagnet is explored and the vertical velocity of bridge is estimated. Finally, numerical and experimental results illustrating the stability improvement of the vehicle-bridge interaction system are provided.

    The explosive growth in access to the Internet has led to a commensurate increase in the availability, anonymity, and affordability of pornography. An emerging body of research has shown associations between pornography and certain behaviors and attitudes; yet, how pornography actually influences these outcomes has not been documented. In two studies (Study 1 N = 969; Study 2 N = 992) we examined the hypothesis that pornography influences potentially risky sexual behavior (hooking up) among emerging adults via sexual scripts. Our results demonstrate that more frequent viewing of pornography is associated with a higher incidence of hooking up and a higher number of unique hook up partners. We replicated these effects both cross-sectionally and longitudinally while accounting for the stability of hook ups over the course of an academic semester. We also demonstrated that more frequent viewing of pornography is associated with having had more previous sexual partners of all types, more one occasion sexual partners ("one night stands"), and plans to have a higher number of sexual partners in the future. Finally, we provided evidence that more permissive sexual scripts mediated the association between more frequent pornography viewing and hooking up. We discuss these findings with an eye toward mitigating potential personal and public health risks among emerging adults. PMID:25239659

    2016-03-20

    This paper investigates the way in which Robert Hooke constructed his microscopical observations. His Micrographia is justifiably famous for its detailed engravings, which communicated Hooke's observations of tiny nature to his readers, but less attention has been paid to how he went about making the observations themselves. In this paper I explore the relationship between the materiality of his instrument and the epistemic images he produced. Behind the pictures lies an array of hidden materials, and the craft knowledge it took to manipulate them. By investigating the often counter-theoretical and conflicting practices of his ingenious microscope use, I demonstrate the way in which Hooke crafted the microworld for his readers, giving insight into how early modern microscopy was understood by its practitioners and audience.

    Full Text Available The broad-snouted caiman, Caiman latirostris, is widely distributed in countries of South America. In Brazil it is considered an endangered species because of natural habitat destruction and illegal hunting.  In reptiles, the thyroid gland plays an integral part in ecdysis, reproduction, tail regeneration, growth, endocrine function and metabolism rate. The aim of the present study was to characterize the thyroid gland morphology of C. latirostris, based on histochemical and immunohistochemical techniques. The thyroid glands were fixed in Bouin's fluid and serial cross sections were stained with hematoxylin-eosin, Mallory’s trichrome, periodic acid-Schiff (PAS and Alcian blue (AB pH 1.5 and 2.5. The immunohistochemical technique for 5-HT-IR cells was used. The thyroid gland has a dense irregular connective tissue forms a capsule enveloping the gland. There are several follicular acini of varying size lined by simple cuboidal or columnar epithelium in the thyroid gland. The follicles are connected by interfollicular connective tissue which contains blood vessels. We observed the presence of lymph nodes around the entire gland. There was a positive PAS reaction and negative AB reaction in the colloid. 5-HT-IR cells were detected around the follicle cells. No striking morphological differences were observed between C. latirostris and other domesticated mammals.

    PurposeThe aim of the study was to retrospectively evaluate simultaneous multiple hook wire placement outcomes before video-assisted thoracoscopic surgery (VATS).Materials and MethodsThirty-eight procedures were performed on 35 patients (13 men and 22 women; mean age, 59.9 years) with 80 lung lesions (mean diameter 7.9 mm) who underwent simultaneous multiple hook wire placements for preoperative localizations. The primary endpoints were technical success, complications, procedure duration, and VATS outcome; secondary endpoints included comparisons between technical success rates, complication rates, and procedure durations of the 238 single-placement procedures performed. Complications were also evaluated.ResultsIn 35 procedures including 74 lesions, multiple hook wire placements were technically successful; in the remaining three procedures, the second target placement was aborted because of massive pneumothorax after the first placement. Although complications occurred in 34 procedures, no grade 3 or above adverse event was observed. The mean procedure duration was 36.4 ± 11.8 min. Three hook wires dislodged during patient transport to the surgical suite. Seventy-four successfully marked lesions were resected. Six lesions without hook wires were successfully resected after detection by palpation with an additional mini-thoracotomy or using subtle pleural changes as a guide. The complication rates and procedure durations of multiple-placement procedures were significantly higher (P = 0.04) and longer (P < 0.001) than those in the single-placement group, respectively, while the technical success rate was not significantly different (P = 0.051).ConclusionsSimultaneous multiple hook wire placements before VATS were clinically feasible, but increased the complication rate and lengthened the procedure time

    Subsurface macro-inclusions and hooks are detrimental to the surface quality of deep-drawing steel sheets. However, little is known about the relationship between macro-inclusions and hooks. Thus, in this work, two ultralow carbon (ULC) steel slabs and two low carbon (LC) aluminum-killed steel slabs were sampled to study the relationship between hooks and subsurface macro-inclusions, which were detected on the cross-sections of steel samples with an area of 56058 mm2 using an automated scanning electron microscopy/energy-disper-sive X-ray spectroscopy system. Results show that subsurface inclusions larger than 200 μm were almost entrapped by hook structures, whereas the location of other inclusions smaller than 200μm had no obvious dependence on the location of solidified hooks. Furthermore, the number density (ND) of subsurface inclusions larger than 200μm decreased from 0.02 to 0 cm-2 in ULC steel as the mean hook depth decreased from 1.57 to 1.01 mm. Similar trends were also observed in LC steel. In addition, the detected inclusions larger than 200μm were concentrated in the region near the slab center (3/8 width-5/8 width), where hook depths were also larger than those at any other locations. Therefore, minimizing the hook depth is an effective way to reduce inclusion-induced sliver defects in deep-drawing steels.

    2001-01-01

    Full Text Available Large quantities of antigen in an immunoassay system impair antigen-antibody binding, resulting in low antigen determination. This is called the ′high dose hook effect′. We report this phenomenon in a patient with a large macroprolactinoma. In this patient, the correct estimate of serum prolactin (PRL was obtained only after appropriate dilution of serum. We suggest that in order to avoid the high dose hook effect, the serum PRL be estimated in appropriate dilution in all patients with large pituitary tumours. This is particularly important when the clinical suspicion of high PRL is strong, as in women with amenorrhoea-galactorrhoea and men with long standing hypogonadism.

    The Automation Hooks Architecture Trade Study for Flexible Test Orchestration sought a standardized data-driven alternative to conventional automated test programming interfaces. The study recommended composing the interface using multicast DNS (mDNS/SD) service discovery, Representational State Transfer (Restful) Web Services, and Automatic Test Markup Language (ATML). We describe additional efforts to rapidly mature the Automation Hooks Architecture candidate interface definition by validating it in a broad spectrum of applications. These activities have allowed us to further refine our concepts and provide observations directed toward objectives of economy, scalability, versatility, performance, severability, maintainability, scriptability and others.

    Full Text Available The purposes of the present study were morphometric characterization of rostellar hooks of Taenia multiceps and to investigate the association of hook length variation and the variability within two mitochondrial genes of sheep isolates of the parasite.Up to 4500 sheep brains were examined for the presence of C. cerebralis. Biometric characters based on the larval rostellar hook size were measured for each individual isolate. Representative mitochondrial CO1 and 12S rRNA gene sequences for each of the isolates were obtained from NCBI GenBank. Morphometric and genetic data were analyzed using cluster analysis, Interclass Correlation Coefficient (ICC and random effects model.One hundred and fourteen sheep (2.5% were found infected with the coenuri. The minimum and maximum number of scoleces per cyst was 40 and 550 respectively. Each scolex contained 22-27 hooks arranged in two rows of large and small hooks. The average total length of the large and small hooks was 158.9 and 112.1 μm, respectively. Using ICC, statistically significant clusters of different hook sizes were identified within the isolates. The length of the large and small hooks was significantly associated with the variability in mitochondrial 12S rRNA gene.Taenia multiceps, is a relatively important zoonotic infection in Iranian sheep with the prevalence rate of 2.5%. Hook length analysis revealed statistically significant difference among individual isolates. Associations between the rostellar hook length and variability in the mitochondrial 12S rRNA was documented.

    This study examined the presence of norm overestimation in both injunctive and descriptive norms about hooking up. An online survey was completed by 186 college students (127 women). Overestimation was examined for hooking up as a global category, as well as for six specific behaviors. The role of norms in predicting hooking up was also examined using hierarchical multiple regression analyses. The predictive role of sensation-seeking, sociosexual orientation, self-esteem, and alcohol drinking status was also examined. Injunctive norm overestimation was present for less intimate behaviors (kissing and non-genital touching); only women showed overestimation for more intimate behaviors (genital touching, receiving oral sex, giving oral sex, and intercourse). Descriptive norms were overestimated across the board. Injunctive norms were poor predictors of behavior. Descriptive norms were good predictors only for less intimate behaviors, a pattern similar to that observed for drinking status. Ultimately, participants' level of personal comfort was the best predictor of participation in the most intimate behaviors, including oral sex and sexual intercourse. PMID:21919644

    Full Text Available High Mobility Group A proteins (HMGA1 and HMGA2 are architectural nuclear factors involved in development, cell differentiation, and cancer formation and progression. Here we report the cloning, developmental expression and functional analysis of a new multi-AT-hook factor in Xenopus laevis (XHMG-AT-hook that exists in three different isoforms. Xhmg-at-hook1 and 3 isoforms, but not isoform 2, are expressed throughout the entire development of Xenopus, both in the maternal and zygotic phase. Localized transcripts are present in the animal pole in the early maternal phase; during the zygotic phase, mRNA can be detected in the developing central nervous system (CNS, including the eye, and in the neural crest. We show evidence that XHMG-AT-hook proteins differ from typical HMGA proteins in terms of their properties in DNA binding and in protein/protein interaction. Finally, we provide evidence that they are involved in early CNS development and in neural crest differentiation.

    Hooking up is defined as a physical encounter between two people who are not romantically committed. This study explored whether there were subgroups of young adults with unique reactions to hooking up (N = 879). Psychosocial predictor variables (gender, depression, loneliness, intoxication level, college adjustment, and hope for a committed relationship) were investigated along with emotional reactions as the outcome variables. Through the use of cluster analysis, four distinct clusters were identified: Happy Hopeful, Content Realist, Used and Confused, and Disappointed and Disengaged. The majority (62 %) of the sample reported mostly positive reactions to hooking up and fell within the Happy Hopeful or Content Realist clusters. Protective factors in these two clusters included hope for a committed relationship, having realistic expectations, and healthy psychological adjustment. The Used and Confused and Disappointed and Disengaged clusters reported the most negative hooking up reactions and consisted of 38 % of the overall sample. These two groups reported increased depression and loneliness symptoms and lower levels of social adjustment as compared to those clusters with more positive reactions. PMID:24872187

    Full Text Available Black Studies scholar and critic, bell hooks, offers many insightful analyses of American life in her book Outlaw Culture. hooks levels a quick claim that Americans “have to go to films outside America to find any vision of redemptive love in films that depict interracial relationships, but she doesn't provide an analysis of a foreign film to illustrate her accusation. This work seeks to utilise hooks race theories to interrogate constructions of interracial relationships in select global art cinemas, particularly how these movies seek to understand postcolonial violations, transnational migration, and globalisation anxieties in Jean Luc Godard's Le Petit Soldat (1960, Tomas Guterrez Alea's Memories of Underdevelopment, and Rainer Werner Fassbinder's Ali: Fear Eats the Soul (1974. Framing this discussion is the forty-year span between the release of Guess Who's Coming to Dinner and Guess Who, which depict interracial coupling between a black male and white female in the late sixties and a white male and black female in 2005. Analysing the use of race in global cinema may allow American audiences the necessary critical distance to see how ‘other’ movies construct interracial relationships to instigate a form cultural atonement, an agenda hooks sees absent in American film yet fails to prove in foreign film.

  11. Hepatic β-oxidation and regulation of carnitine palmitoyltransferase (CPT) I in blunt snout bream Megalobrama amblycephala fed a high fat diet.

    High-fat diets may promote growth, partly through their protein-sparing effects. However, high-fat diets often lead to excessive fat deposition, which may have a negative impact on fish such as poor growth and suppressive immune. Therefore, this study investigated the effects of a fat-rich diet on the mechanisms of fat deposition in the liver. Three-hundred blunt snout bream (Megalobrama amblycephala) juveniles (initial mass 18.00 ± 0.05 g) were fed with one of two diets (5% or 15% fat) for 8 weeks. β-Oxidation capacity and regulation of rate-limiting enzymes were assessed. Large fat droplets were present in hepatocytes of fish fed the high-fat diet. This observation is thought to be largely owing to the reduced capacity for mitochondrial and peroxisomal β-oxidation in the livers of fish fed the high-fat diet, as well as the decreased activities of carnitine palmitoyltransferase (CPT) I and acyl-CoA oxidase (ACO), which are enzymes involved in fatty-acid metabolism. Study of CPT I kinetics showed that CPT I had a low affinity for its substrates and a low catalytic efficiency in fish fed the high-fat diet. Expression of both CPT I and ACO was significantly down-regulated in fish fed the high-fat diet. Moreover, the fatty-acid composition of the mitochondrial membrane varied between the two groups. In conclusion, the attenuated β-oxidation capacity observed in fish fed a high-fat diet is proposed to be owing to decreased activity and/or catalytic efficiency of the rate-limiting enzymes CPT I and ACO, via both genetic and non-genetic mechanisms.

    Organochlorine compounds (OCCs) are toxic and have been identified as endocrine-disrupting chemicals (EDCs). The broad-snouted Caiman (Caiman latirostris) is an oviparous species widely distributed in South America with potential to accumulate OCCs. The eggshell is formed during passage of the eggs through the oviduct. Since the oviduct is a target of hormone actions, exposure to OCCs could modify eggshell quality, thus affecting clutch viability. Eight clutches were collected from wetlands of Parana River tributaries, in north-eastern Argentina. Two to four eggs per clutch were used to establish the burden of OCCs, eggshell thickness and eggshell porosity. The remaining eggs were incubated in controlled conditions. Ten days after hatching, hatchling survival was assessed. Organochlorine pesticide residues (OCPs) were found in all clutches, while polychlorinated biphenyls (PCBs) were present in all but one clutch. The principal contributors to the OCP burden were members of the DDT family and oxychlordane. Eggshell thickness was 400.9±6.0 μm and, unexpectedly, no association between eggshell thickness and the OCC burden was found. The number of pores in the outer surface was 25.3±4.3 pores/cm². A significant inverse correlation between porosity and OCC burden was found (Pearson r= -0.81, p= 0.01). Furthermore, a decrease in caiman survival with decreased pore density was observed (Pearson r= 0.73, p= 0.04). Our findings highlight another potential negative impact of current and past use of OCCs on wildlife species. PMID:24054891

    This study aimed to figure out the effects of berberine on growth performance, immunity, oxidative stress and hepatocyte apoptosis of blunt snout bream (Megalobrama amblycephala) fed with high-fat diet. 320 fish (80.00 ± 0.90 g) were divided randomly into four trial groups (each with four replicates) and fed with 4 diets (normal diet, normal diet with 50 mg/kg berberine, high-fat diet, high-fat diet with 50 mg/kg berberine), respectively. At the end of the feeding trial, ammonia stress test was carried out for 5 days. The result showed the growth performance, immune parameters including plasm acid phosphatase (ACP) activities, lysozyme (LYZ) activities and alternative complement C3 and C4 contents were suppressed in fish fed with high-fat diets but improved in berberine diets compared with control (normal diet). Hepatopancreas oxidative status, the malondialdehyde (MDA), protein carbonyl (PC) and lipid peroxide (LPO) were increased significantly (P < 0.05) when fish were fed with high-fat diets. Berberine could slow the progression of the oxidative stress induced by high-fat through increasing superoxide dismutase (SOD) activities and total sulfydryl (T-SH) levels of fish. And the hepatocyte apoptosis in the high-fat group could also be alleviated by berberine. After the ammonia stress test, the accumulative mortality was extremely (P < 0.05) low in fish fed high-fat diet with berberine compared to other groups. It was concluded berberine as a functional feed additive significantly inhibited the progression of oxidative stress, reduced the apoptosis and enhanced the immunity of fish fed with high-fat diet.

    2015-01-01

    Functional morphology and biomechanical properties of hook structures functioning as attachment devices in the leaning climbers Rosa arvensis, Rosa arvensis ‘Splendens‘, Asparagus falcatus and Asparagus setaceus are analysed in order to investigate the variability in closely related species as well as convergent developments of hook structure and properties in distant systematic lineages (monocots and dicots). Prickles and spines were characterised by their size, orientation and the maximum force measured at failure in mechanical tests performed with traction forces applied at different angles. In Rosa arvensis and Rosa arvensis ‘Splendens‘ three types of prickles differing largely in geometrical and mechanical properties are identified (prickles of the wild species and two types of prickles in the cultivar). In prickles of Rosa arvensis no particular orientation of the prickle tip is found whereas in the cultivar Rosa arvensis ‘Splendens‘ prickles gradually gain a downward-orientation due to differential growth in the first weeks of their development. Differences in mechanical properties and modes of failure are correlated to geometrical parameters. In Asparagus falcatus and Asparagus setaceus spines are composed of leaf tissue, stem tissue and tissue of the axillary bud. Between species spines differ in size, orientation, distribution along the stem, tissue contributions and mechanical properties. The prickles of Rosa arvensis and its cultivar and the spines of the studied Asparagus species have several traits in common: (1) a gradual change of cell size and cell wall thickness, with larger cells in the centre and smaller thick-walled cells at the periphery of the hooks, (2) occurrence of a diversity of shape and geometry within one individual, (3) failure of single hooks when submitted to moderate mechanical stresses (Fmax/basal area < 35 N/mm²) and (4) failure of the hooks without severe stem damage (at least in the tested wild species).

    Atomic force microscopy (AFM) is a highly successful technique for imaging nanometre-sized samples and measuring pico- to nano-newton forces acting between atoms and molecules. When it comes to the manipulation of larger samples with forces of tens and hundreds of nano-newtons, however, the present chemistry-based modification protocols for functionalizing AFM cantilevers to achieve the formation of covalent/non-covalent linkages between the AFM probe and the sample surface do not produce strong enough bonds. For the purpose of measuring the fracture strength and other mechanical properties of stress fibres (SFs) in living as well as semi-intact fibroblast cells, we fabricated an AFM probe with a hooking function by focused ion beam technology and used the AFM probe hook to capture, pull and eventually sever a chosen SF labelled with green or red fluorescent protein.

    Congenital adrenal hyperplasia (CAH) describes a group of disorders characterized by enzyme defects in adrenal steroidogenesis. 21-hydroxylase deficiency (21-OHD) is the most commonly encountered form. The analysis of steroids in pediatric cases requires high-sensitivity assays. A 14-year-old Syrian girl was referred for evaluation of short stature, amenorrhea, and hirsutism. On physical examination, breast development was Tanner stage 1. She had a phallic clitoris with a single urogenital orifice. Laboratory findings revealed primary adrenal deficiency with high androgen levels and low levels of 17-hydroxyprogesterone (17-OHP), (<0.05 ng/mL) and estrogen. This unexpected result led to suspicion of a high-dose hook effect. The measurement was repeated after 1/10 dilution of serum, and a high level of 17-OHP (115.4 ng/mL) was detected with the same test-enzyme-linked immunosorbent assay (ELISA). Simple virilizing form of CAH (21-OHD) was suspected and confirmed with genetic analysis. After initiation of glucocorticoid therapy, breast development was noted along with a decrease in testosterone level and an increase in estrogen level. To our knowledge, this is the first case report of hook effect for 17-OHP immunoassay in a patient with 21-OHD. High-dose hook effect should be suspected in patients with CAH when the test results are incompatible with one another. Additionally, this case demonstrates that a high testosterone level can block aromatase activity and consequently also estrogen production and breast development. PMID:26777045

  14. Efficient Disengaging Hooks System Based on Constant-Power Speed Regulation of Frequency Converter

    Full Text Available In the traditional port, disengaging hook system adopts a three-phase power frequency power to drive a three-phase asynchronous motor. The operation is simple and the maintenance is convenient. However, it still keeps the speed of mooring lines constant. Under the light-load condition, the work efficiency could be affected because of the low speed. To solve this problem, we start the research in speed control of disengaging hook. By using variable frequency control technology to transform the original system and using frequency converter to carry on the constant-power speed regulation, technicians also adopt vector control algorithm with PG to achieve adjustable speed of cable volume. The motor is under no load or light load state with high-speed after starting and turns into low-speed through full load. It makes motor stay in constant-power state when it works. This design solves the low-efficiency of disengaging hook in the past and makes system achieve adjustable motor speed. In this design and application, not only can technicians reduce the initial cost, but also they can reduce operating costs markedly by adopting energy-saving control equipment at the same time.

    Wu, X. B.

    2006-06-01

    Full Text Available Four body-size and fourteen head-size measurements were taken from each Chinese alligator (Alligator sinensis according to the measurements adapted from Verdade. Regression equations between body-size and head-size variables were presented to predict body size from head dimension. The coefficients of determination of captive animals concerning body- and head-size variables can be considered extremely high, which means most of the head-size variables studied can be useful for predicting body length. The result of multivariate allometric analysis indicated that the head elongates as in most other species of crocodilians. The allometric coefficients of snout length (SL and lower ramus (LM were greater than those of other variables of head, which was considered to be possibly correlated to fights and prey. On the contrary, allometric coefficients for the variables of obita (OW, OL and postorbital cranial roof (LCR, were lower than those of other variables.

    A novel combined near- and mid-infrared (NIR and MIR) spectroscopic method has been researched and developed for the analysis of complex substances such as the Traditional Chinese Medicine (TCM), Illicium verum Hook. F. (IVHF), and its noxious adulterant, Iuicium lanceolatum A.C. Smith (ILACS). Three types of spectral matrix were submitted for classification with the use of the linear discriminant analysis (LDA) method. The data were pretreated with either the successive projections algorithm (SPA) or the discrete wavelet transform (DWT) method. The SPA method performed somewhat better, principally because it required less spectral features for its pretreatment model. Thus, NIR or MIR matrix as well as the combined NIR/MIR one, were pretreated by the SPA method, and then analysed by LDA. This approach enabled the prediction and classification of the IVHF, ILACS and mixed samples. The MIR spectral data produced somewhat better classification rates than the NIR data. However, the best results were obtained from the combined NIR/MIR data matrix with 95-100% correct classifications for calibration, validation and prediction. Principal component analysis (PCA) of the three types of spectral data supported the results obtained with the LDA classification method.

    The objective of the Red HookIBay Ridge project was to evaluate proposed dredged material from these two areas to determine its suitability for unconfined ocean disposal at the Mud Dump Site. Sediment samples were collected from the Red Hook/Bay Ridge project areas. Tests and analyses were conducted. The evaluation of proposed dredged material from the Red Hook/Bay Ridge project areas consisted of bulk sediment chemical analyses, chemical analyses of dredging site water and elutriate, water-column and benthic acute toxicity tests. Twenty-four individual sediment core samples were collected from these two areas and analyzed for grain size, moisture content, and total organic carbon (TOC). Three composite sediment samples, representing Red Hook Channel and the two Bay Ridge Reaches to be dredged, were analyzed for bulk density, specific gravity, metals, chlorinated pesticides, polychlorinated biphenyl (PCB) congeners, polynuclear aromatic hydrocarbons (PAH), and 1,4-dichlorobenzene. Dredging site water and elutriate water, which is prepared from the suspended-particulate phase (SPP) of the three Red Hook Bay Ridge sediment composites, were analyzed for metals, pesticides, and PCBS. Benthic acute toxicity tests were performed. Water-column or SPP toxicity tests were performed. Bioaccumulation tests were also conducted.

    International Nuclear Information System (INIS)

    Objective: To evaluate the feasibility,safety and clinical value of CT-guided localization with a Hook-wire system for nodular pulmonary lesions before video-assisted thoracoscopic resection (VATS). Methods: The records of all patients undergoing VATS resection for solitary pulmonary nodules preoperatively localized by CT-guided a Hook-wire system were assessed with respect to failure to localize the lesion by the Hook-wire system, conversion thoracotomy rate, duration of operation, postoperative complications, and histology of nodular pulmonary lesions. Results: Sixty-eight patients with seventy four nodules underwent VATS resections. Preoperative CT-guided Hook-wire localization succeeded in all patients (100.0%). Conversion thoracotomy was necessary in 2 patients. The average operative time was (15 ± 6)min. Asymptomatic complication rate was 70.6% (48/68), asymptomatic pneumothorax rate, asymptomatic hemorrhage rate and simultaneous pneumothorax and bleeding rate were 45.6% (31/68), 25.0% (17/68) and 4.4% (3/68), respectively. The mean hospitalization was (15±6) days. Histological assessment revealed primary lung eancer(NSCLC) in 30, metastasis in 18, and nonmalignant disease in 26 nodules. Conclusions: Video-assisted thoracoscopic resection of nodular pulmonary lesions previously localized by a CT-guided Hook-wire system is related to a low conversion thoracotomy rate, short operation time, and high safety. It for differential diagnosis and treatment. (authors)

  1. "Hook"-calibration of GeneChip-microarrays: Chip characteristics and expression measures

    Directory of Open Access Journals (Sweden)

    Krohn Knut

    2008-08-01

    Full Text Available Abstract Background Microarray experiments rely on several critical steps that may introduce biases and uncertainty in downstream analyses. These steps include mRNA sample extraction, amplification and labelling, hybridization, and scanning causing chip-specific systematic variations on the raw intensity level. Also the chosen array-type and the up-to-dateness of the genomic information probed on the chip affect the quality of the expression measures. In the accompanying publication we presented theory and algorithm of the so-called hook method which aims at correcting expression data for systematic biases using a series of new chip characteristics. Results In this publication we summarize the essential chip characteristics provided by this method, analyze special benchmark experiments to estimate transcript related expression measures and illustrate the potency of the method to detect and to quantify the quality of a particular hybridization. It is shown that our single-chip approach provides expression measures responding linearly on changes of the transcript concentration over three orders of magnitude. In addition, the method calculates a detection call judging the relation between the signal and the detection limit of the particular measurement. The performance of the method in the context of different chip generations and probe set assignments is illustrated. The hook method characterizes the RNA-quality in terms of the 3'/5'-amplification bias and the sample-specific calling rate. We show that the proper judgement of these effects requires the disentanglement of non-specific and specific hybridization which, otherwise, can lead to misinterpretations of expression changes. The consequences of modifying probe/target interactions by either changing the labelling protocol or by substituting RNA by DNA targets are demonstrated. Conclusion The single-chip based hook-method provides accurate expression estimates and chip-summary characteristics

  7. Conformal Newton–Hooke algebras, Niederer's transformation and Pais–Uhlenbeck oscillator

    International Nuclear Information System (INIS)

    Dynamical systems invariant under the action of the l-conformal Newton–Hooke algebras are constructed by the method of nonlinear realizations. The relevant first order Lagrangians together with the corresponding Hamiltonians are found. The relation to the Galajinsky and Masterov [24] approach as well as the higher derivatives formulation is discussed. The generalized Niederer's transformation is presented which relates the systems under consideration to those invariant under the action of the l-conformal Galilei algebra [25]. As a nice application of these results an analogue of Niederer's transformation, on the Hamiltonian level, for the Pais–Uhlenbeck oscillator is constructed

    Full Text Available Background: The goal of managing the comminuted fracture of lateral malleolus is to restore length, rotation and alignment which might be more challenging with extensive comminution around the area of the distal tip. The common osteosynthesis techniques such as the one-third tubular plate, tension band wiring, K-wires, screws, or intramedullary nail may be insufficient in cases with a comminuted lateral malleolus. The anatomical hook plate is an alternative implant in such cases. We present our results of the comminuted lateral malleolar fractures (Weber A, B, managed by open reduction and internal fixation (ORIF with an anatomical hook plate of lateral malleolus (Königsee Implant Company, Germany. Materials and Methods: We retrospectively reviewed 20 patients of comminuted fracture of distal lateral malleolus between 2008 and 2010. There were 12 males and 8 females, right side was involved in 18 patients and left in 2. The mean age was 51.9 years (range 18-75 years. The fractures were categorized by Denis-Weber classification type A (n=1, B1 (n=1, B2 (n=13 and B3 (n=5. Nineteen cases were of closed injury and one of open injury (Gustilo Anderson type II. These patients underwent ORIF with a lateral malleolus anatomical hook plate. Followup including radiographs and clinical examinations were performed. The American Orthopedic Foot and Ankle Society (AOFAS ankle hindfoot scores were documented at followups. Results: The mean followup was 21.4 months (range 16-27 months. The average AOFAS score was 94.3 (range 78-100 points. A stable anatomic reduction and bony union were obtained in all the cases. The average time was 3.1 months (range 2.5-4 months. Four cases had complications like posttraumatic osteoarthritis, hardware impingement and superficial wound infection. Conclusion: A reasonably good stability can be obtained in distal most comminuted fractures of lateral malleolus with a lateral malleolus anatomical hook plate. We believe this

    Full Text Available An experiment was done to quantify species-specific variation in temporal hooking rates from demersal longlines targeting various carcharhinids off south eastern Australia, with a view to reducing the incidental catches of protected species, including the scalloped hammerhead Sphyrna lewini, great hammerhead Sphyrna mokarran and grey nurse Carcharias taurus. The longline comprised a 9600 m mainline, separated into four sections (termed lines each with 120 gangions (20 m apart rigged with hook timers and 16/0 circle hooks baited with either sea mullet Mugil cephalus or eastern Australian salmon Arripis trutta. The mainline was deployed on each of 17 nights (between 19:30 and 23:30 h, with two lines retrieved after 7 and 14 h respectively. From a total of 8160 hooks, 246 timers were activated without hooking fish. Twenty-two species comprising 684 individuals were caught, including 52 S. lewini, 12 C. taurus, 11 S. mokarran and 1 loggerhead turtle Caretta caretta. Several environmental factors, including water temperature, moon phase and depth had mostly homogeneous, positive effects on catches. The only identified variables that might be used to considerably reduce the catches of Sphyrna were soak time and/or diurnal gear retrieval, with most individuals hooked during daylight. Simply mandating shorter deployments and within nocturnal retrieval might limit exploitation, especially among juveniles (<150cm total length. For the studied fishery to approach sustainability, future research is required to investigate other gear modifications for improving size and species selectivity, and/or operational procedures for mitigating discard and escape mortalities.

    PurposeWe retrospectively evaluated the results of the transfissural route for preoperative localization with a short hook wire and suture system for video-assisted thoracoscopic surgery (VATS).MethodsEleven patients with 11 tumors underwent CT-guided transfissural placement of a hook wire before VATS. This route was selected for all patients, because the distance between the tumor and interlobar fissure was much shorter than the required distance traversed using the conventional approach. Complications were evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events Version 4.0.ResultsThe hook wire was successfully placed using the transfissural route in all but one case. Of these ten successful placements, two tumors needed a second puncture for optimal placement, because the CT scan showed that the first hook wire was not properly placed in the lung. In one patient, we did not attempt replacement after the first placement was incorrect. In ten successful procedures, the mean distance traversed in the parenchyma of the unaffected lung lobe was 27.9 mm. The distance between the pleura and placed hook wire was significantly shorter than the estimated distance between the pleura and hook wire using the conventional route (mean 16.3 vs. 40.9 mm; P = 0.0002). Grade 1 adverse events occurred (11 pneumothoraxes and 4 pulmonary hemorrhages). No grade 2 or higher adverse event was observed.ConclusionsThe transfissural route used for preoperative localization before VATS is useful for selected patients because this route may allow for more limited lung parenchyma resection.

    Hexane extract obtained from leaves of Eucalyptus citriodora Hook was tested against larvae of Anopheles stephensi Liston, Culex quinquefasciatus Say and Aedes aegypti Linn to assess its toxicity and growth inhibiting activity. The results showed better activity of hexane extract against larvae of An. stephensi Liston as compared to the larvae of Cx. quinquefasciatus Say and Ae. aegypti Linn. The LC50 values against IVth instar larvae of three species were 69.86, 81.12 & 91.76 ppm respectively after 24 hours and 26.7, 29.9 & 38.8 ppm respectively after 72 hours. At lowest concentration viz. 10 ppm, 73% larvae of An. stephensi Liston failed to emergence as adult mosquito while in Cx. quinquefasciatus Say and Ae. aegypti Linn only 10 & 6% larvae failed to emerge. Further observations showed some morphological abnormalities in same pupae which could not moult normally. These results clearly indicated growth inhibition effect of the hexane extract of Eucalyptus against mosquito larvae, particularly Anopheles species. Thus Eucalyptus citriodora Hook, which is commonly found in Northern India, has a great potential for the development of an eco-friendly herbal insecticidal product for control of mosquito breeding.

    Congenital adrenal hyperplasia (CAH) describes a group of disorders characterized by enzyme defects in adrenal steroidogenesis. 21-hydroxylase deficiency (21-OHD) is the most commonly encountered form. The analysis of steroids in pediatric cases requires high-sensitivity assays. A 14-year-old Syrian girl was referred for evaluation of short stature, amenorrhea, and hirsutism. On physical examination, breast development was Tanner stage 1. She had a phallic clitoris with a single urogenital orifice. Laboratory findings revealed primary adrenal deficiency with high androgen levels and low levels of 17-hydroxyprogesterone (17-OHP), (breast development was noted along with a decrease in testosterone level and an increase in estrogen level. To our knowledge, this is the first case report of hook effect for 17-OHP immunoassay in a patient with 21-OHD. High-dose hook effect should be suspected in patients with CAH when the test results are incompatible with one another. Additionally, this case demonstrates that a high testosterone level can block aromatase activity and consequently also estrogen production and breast development. PMID:26777045

    This paper considers how certain functions of online hook-up devices are participating in the emergence of new forms of sexual relation, new distributions of intimacy and new sexual arrangements. Though not without precedent, it argues that online hook-up devices generally act in gay culture as 'framing devices', framing sex as a 'no-strings' encounter via their default application. These frames are variously rejected, reconfigured, re-embedded or confounded by participants; they become subject to various forms of overflowing. Understanding this dynamic, its typical forms of connection and estrangement, is pivotal for grasping the emergence of new forms of sexual community and new sexual publics among gay men--and/or 'un-community', as some have put it. My analysis prompts a series of methodological reflections wrought from the encounter it stages between queer theory and Science and Technology Studies. At a time when marriage and monogamy are increasingly monopolising the public discourse of gay life, digital devices are affording novel ways of arranging sex, intimacy and sexual community, with their own qualities and limitations.

    Hooke's Law is analyzed taking the Second Law of Thermodynamics into consideration. It is shown that the energy of a spring isn't always 1/2 k xx - this value is actually the energy of the spring plus the energy of the atmosphere that surrounds it. On a quasi-isentropic aproximation in which the dynamic force is approximately the same as the static force, k is not a constant. Only by considering an ideal spring where k is constant and only on a static regime, can we say the energy is 1/2 k xx. For any dynamic regime of such an ideal spring, the energy of the spring is a function of its temperature and therefore is different from 1/2 k xx. If any given mass is moving attached to an ideal spring, the movement will eventually cease even if such movement occurs in vacuum. The dynamic force is not the static force kx. The Second Law of Thermodynamics is essential in order to formulate Hooke's Law.

  20. A survey of small RNA population during FR-induced apical hook opening

    Full Text Available Photomorphogenesis is a mechanism employed by plants to regulate their architecture and developmental program in response to light conditions. As they emerge into light for the first time, dark-grown seedlings employ a rapid and finely-controlled photomorphogenic signaling network. Small RNAs have increasingly been revealed to play an important role in regulating multiple aspects of plant development, by modulating the stability of mRNAs. The rapid alteration of the mRNA transcriptome is a known hallmark of the de-etiolation response, thus we investigated the small RNA transcriptome during this process in specific seedling tissues. Here we describe a survey of the small RNA expression profile in four tissues of etiolated soybean seedlings, the cotyledons, hypocotyl and the convex and concave sides of the apical hook. We also investigate how this profile responds to a one-hour far-red light treatment. Our data suggests that miRNAs show a different global profile between these tissues and treatments, suggesting a possible role for tissue- and treatment-specific expression in the differential morphology of the seedling on de-etiolation. Further evidence for the role of miRNA in light-regulated development is given by the de-etiolation responses of a hypomorphic ago1 mutant, which displays reduced and delayed photomorphogenic responses in apical hook and cotyledon angle to far-red light.

    To evaluate the feasibility and efficacy of US-guided preoperative wire localization of nonpalpable breast lesions. US-guided preoperative wire localization was performed upon 45 nonpalpable breast lesions including 14 nonpalpable masses, 11 nonpalpable masses with microcalcifications, 11 ductal lesions, 9 with microcalcifications. No local anesthesia was performed during the localization procedure. Under the US-guidance, the needle with the hook-wire was inserted into the lesion until the hook of the wire reached 1 cm beyond the posterior margin of the lesion. Precise wire positioning was confirmed by mammography. Specimen radiography or specimen ultrasonography was performed in all cases. US-guided preoperative wire localization was successfully achieved in all cases. The time required for US-guided wire localization was less than five minutes. All lesions were successfully removed by surgical excision. Successful removal was confirmed by specimen radiography or specimen ultrasonography, gross findings of the specimen and consistency between radiographic and pathologic findings. The histologic diagnosis of 45 lesions were 7 ductal carcinoma in situ, 8 invasive ductal carcinoma, 6 fibroadenoma, 8 intraductal papilloma, 2 atypical ductal hyperplasia, and 14 fibrocystic changes. No complications were occurred during and after the procedure. US-guided preoperative wire localization for excisional biopsy is simple, safe, and accurate method in the histologic diagnosis of nonpalpable breast lesions detectable with ultrasonography.

  9. "Hook"-calibration of GeneChip-microarrays: Theory and algorithm

    Directory of Open Access Journals (Sweden)

    Preibisch Stephan

    2008-08-01

    Full Text Available Abstract Background: The improvement of microarray calibration methods is an essential prerequisite for quantitative expression analysis. This issue requires the formulation of an appropriate model describing the basic relationship between the probe intensity and the specific transcript concentration in a complex environment of competing interactions, the estimation of the magnitude these effects and their correction using the intensity information of a given chip and, finally the development of practicable algorithms which judge the quality of a particular hybridization and estimate the expression degree from the intensity values. Results: We present the so-called hook-calibration method which co-processes the log-difference (delta and -sum (sigma of the perfect match (PM and mismatch (MM probe-intensities. The MM probes are utilized as an internal reference which is subjected to the same hybridization law as the PM, however with modified characteristics. After sequence-specific affinity correction the method fits the Langmuir-adsorption model to the smoothed delta-versus-sigma plot. The geometrical dimensions of this so-called hook-curve characterize the particular hybridization in terms of simple geometric parameters which provide information about the mean non-specific background intensity, the saturation value, the mean PM/MM-sensitivity gain and the fraction of absent probes. This graphical summary spans a metrics system for expression estimates in natural units such as the mean binding constants and the occupancy of the probe spots. The method is single-chip based, i.e. it separately uses the intensities for each selected chip. Conclusion: The hook-method corrects the raw intensities for the non-specific background hybridization in a sequence-specific manner, for the potential saturation of the probe-spots with bound transcripts and for the sequence-specific binding of specific transcripts. The obtained chip characteristics in combination

    2016-06-01

    Study Design Biomechanical cadaveric study. Objective Clinical studies indicate that using less-rigid fixation techniques in place of the standard all-pedicle screw construct when correcting for scoliosis may reduce the incidence of proximal junctional kyphosis and improve patient outcomes. The purpose of this study is to investigate whether there is a biomechanical advantage to using supralaminar hooks in place of pedicle screws at the upper-instrumented vertebrae in a multilevel thoracic construct. Methods T7-T12 spines were biomechanically tested: (1) intact; (2) following a two-level pedicles screw fusion from T9 to T11; and after proximal extension of the fusion to T8-T9 with (3) bilateral supra-laminar hooks, (4) a unilateral hook + unilateral screw hybrid, or (5) bilateral pedicle screws. Specimens were nondestructively loaded while three-dimensional kinematics and intradiscal pressure at the supra-adjacent level were recorded. Results Supra-adjacent hypermobility was reduced when bilateral hooks were used in place of pedicle screws at the upper-instrumented level, with statistically significant differences in lateral bending and torsion (p < 0.05 and p < 0.001, respectively). Disk pressures in the supra-adjacent segment were not statistically different among top-off techniques. Conclusions The use of supralaminar hooks at the top of a multilevel posterior fusion construct reduces the stress at the proximal uninstrumented motion segment. Although further data is needed to provide a definitive link to the clinical occurrence of PJK, this in vitro study demonstrates the potential benefit of "easing" the transition between the stiff instrumented spine and the flexible native spine and is the first to demonstrate these results with laminar hooks.

  11. A New Technique for Superselective Catheterization of Arteries: Preshaping of a Micro-Guide Wire into a Shepherd's Hook Form

    International Nuclear Information System (INIS)

    We wanted to introduce a new technique for superselective catheterization of arteries with preshaping of a micro-guide wire into a shepherd's hook form, and this is useful for superselection of small arteries branching at an acute angle from a large parent artery for the treatment of tumors and hemorrhages. We developed a superselective catheterization technique by using preshaping of a micro-guide wire into a shepherd's hook form. We encountered six patients in our practice for whom we failed to catheterize the small tumor-feeding arteries that branched at an acute angle from wide parent arteries during chemoembolization of hepatocellular carcinoma; the parent arteries were the right inferior phrenic artery (n = 4) and the left gastric artery (n = 1) from the celiac axis with celiac stenosis due to compression by the median arcuate ligament and the proper hepatic artery from the gastroduodenal artery (n = 1) in a patient who had celiac axis occlusion with collateral circulation via the pancreaticoduodenal arcade from the superior mesenteric artery. In these consecutive six patients, we tested the usefulness of this new technique with employing preshaping of a micro-guide wire into a shepherd's hook form for superselective catheterization of targeted vessels. The target arteries were successfully catheterized and satisfactory transcatheter arterial chemoembolization was performed in all six patients. There were no significant complications such as arterial dissection. We developed a technique that is effective for superselection of vessels with preshaping of micro-guide wire into a shepherd's hook hook form, and we successfully applied it during chemoembolization of hepatocellular carcinoma. This technique can be useful for superselection of small arteries that branch from a large parent artery at acute angles for the treatment of tumors and hemorrhages

    2016-02-01

    We use recent work of Jonah Blasiak (2012 arXiv:1209.2018) to prove a stability result for the coefficients in the Kronecker product of two Schur functions: one indexed by a hook partition and one indexed by a rectangle partition. We also give nearly sharp bounds for the size of the partition starting with which the Kronecker coefficients are stable. Moreover, we show that once the bound is reached, no new Schur functions appear in the decomposition of Kronecker product. We call this property superstability. Thus, one can recover the Schur decomposition of the Kronecker product from the smallest case in which the superstability holds. The bound for superstability is sharp. Our study of this particular case of the Kronecker product is motivated by its usefulness for the understanding of the quantum Hall effect (Scharf T et al 1994 J. Phys. A: Math. Gen 27 4211-9).

    Full Text Available Jodina rhombifolia (Hook. & Arn. Reissek (Santalaceae is a medicinal plant popularly used as an anti-ulcer medicine. The plant native from Southern Brazil was chemically investigated and tested for its in vivo gastric anti-ulcer property by chloride acid/ethanol model. The chromatographic analysis of the hydroethanol extract of its leaves revealed the presence of C-glycosylflavonoids. From the n-butanol fraction of the hydroethanol extract of its aerial parts, vicenin-2 was isolated as the main component and identified by spectroscopic methods; and, a direct comparison with authentic samples was made. This fraction afforded three other C-glycosylflavonoids: vitexin, orientin and swertisin; all of them identified by direct comparison with authentic samples. We found that the oral administration of aqueous and hydroethanolic extracts led to a significant decrease in the ulcer index.

  14. A viral suppressor protein inhibits host RNA silencing by hooking up with Argonautes

    KAUST Repository

    2010-05-01

    RNA viruses are particularly vulnerable to RNAi-based defenses in the host, and thus have evolved specific proteins, known as viral suppressors of RNA silencing (VSRs), as a counterdefense. In this issue of Genes & Development, Azevedo and colleagues (pp. 904-915) discovered that P38, the VSR of Turnip crinkle virus, uses its glycine/tryptophane (GW) motifs as an ARGONAUTE (AGO) hook to attract and disarm the host\\'s essential effector of RNA silencing. Several GW motif-containing cellular proteins are known to be important partners of AGOs in RNA silencing effector complexes in yeast, plants, and animals. The GW motif appears to be a versatile and effective tool for regulating the activities of RNA silencing pathways, and the use of GW mimicry to compete for and inhibit host AGOs may be a strategy used by many pathogens to counteract host RNAi-based defenses. © 2010 by Cold Spring Harbor Laboratory Press.

    This study was designed to evaluate the biomechanical properties of a hook plate (HP) vs an antiglide (AG) plate for supination-adduction (SAD)-ankle fractures. Identical polyurethane tibial models were obtained and vertical fractures were created. The fractures were stabilized with 1 of the following: one-third tubular plate in an AG fashion with 2 screws proximal to the fracture; an AG plate with an additional screw perpendicular to the vertical shear fragment (MAG), or an HP. Ten models were randomly assigned to each of the 3 groups. The constructs were tested in offset-axial loading and were evaluated for construct stiffness and load-to-failure. The MAG construct yielded better stiffness compared with the AG plate (P MAG and AG was 638 N, and MAG and HP was 530 N (both P MAG fashion provided a stable, strong construct for fixation of vertical shear medial malleolus fractures.

  3. Scaling of precipitation extremes with temperature in the French Mediterranean region: What explains the hook shape?

    2016-04-01

    Expected changes to future extreme precipitation remain a key uncertainty associated with anthropogenic climate change. Extreme precipitation has been proposed to scale with the precipitable water content in the atmosphere. Assuming constant relative humidity, this implies an increase of precipitation extremes at a rate of about 7% °C-1 globally as indicated by the Clausius-Clapeyron relationship. Increases faster and slower than Clausius-Clapeyron have also been reported. In this work, we examine the scaling between precipitation extremes and temperature in the present climate using simulations and measurements from surface weather stations collected in the frame of the HyMeX and MED-CORDEX programs in Southern France. Of particular interest are departures from the Clausius-Clapeyron thermodynamic expectation, their spatial and temporal distribution, and their origin. Looking at the scaling of precipitation extreme with temperature, two regimes emerge which form a hook shape: one at low temperatures (cooler than around 15°C) with rates of increase close to the Clausius-Clapeyron rate and one at high temperatures (warmer than about 15°C) with sub-Clausius-Clapeyron rates and most often negative rates. On average, the region of focus does not seem to exhibit super Clausius-Clapeyron behavior except at some stations, in contrast to earlier studies. Many factors can contribute to departure from Clausius-Clapeyron scaling: time and spatial averaging, choice of scaling temperature (surface versus condensation level), and precipitation efficiency and vertical velocity in updrafts that are not necessarily constant with temperature. But most importantly, the dynamical contribution of orography to precipitation in the fall over this area during the so-called "Cevenoles" events, explains the hook shape of the scaling of precipitation extremes.

  11. Stress Distribution of a Crane Hook by Photoelasticity Using 4-step Phase Shifting Method and finite Element Method

    International Nuclear Information System (INIS)

    An experimental study for a crane hook was performed to investigate the stress distribution along a certain line where the maximum and minimum stresses to be developed. On this line, the isoclinic fringe and/or principal stress direction is constant. The crane hook was modeled into a 2-dimensional plate made of urethane rubber called 'Photoflex' The Photoflex is very sensitive to a load and has low photoelastic fringe constant. The Tardy compensation method with the fringe sharpening process and the 4-step phase shifting method, was used for the photoelastic technique. Experimental results by photoelasticity were compared with the calculated stresses from the simple curved beam theory and tile finite element analysis. Ail the results were close to each other

    The chemical composition of essential oil extracted from Uncaria Hook ("Chotoko" in Japanese), the branch with curved hook of the herbal medicine Uncaria rhynchophylla has been investigated by GC and GC-MS analyses. Eighty-four compounds, representing 90.8% of the total content was identified in oil obtained from Uncaria Hook. The main components i were (E)-cinnamaldehyde (13.4%), α-copaene (8.0%), methyl eugenol (6.8%), δ-cadinene (5.3%), and curcumene (3.6%). The important key aroma-active compounds in the oil were detected by gas chromatography-olfactometry (GC-O) and aroma extract dilution analysis (AEDA), using the flavor dilution (FD) factor to express the odor potency of each compounds. Furthermore, the odor activity value (OAV) has been used as a measure of the relative contribution of each compound to the aroma of the Uncaria Hook oil. The GC-O and AEDA results showed that α-copaene (FD = 4, OAV = 4376), (E)-linalool oxide (FD = 64, OAV = 9.1), and methyl eugenol (FD = 64, OAV = 29) contributed to the woody and spicy odor of Uncaria Hook oil, whereas furfural (FD = 8, OAV = 4808) contributed to its sweet odor. These results warrant further investigations of the application of essential oil from Uncaria Hook in the phytochemical and medicinal fields. PMID:26179003

    By using the path integral approach, we investigate the problem of Hooke's atom (two electrons interacting with Coulomb potential in an external harmonic-oscillator potential) in an arbitrary time-dependent electric field. For a certain infinite set of discrete oscillator frequencies, we obtain the analytical solutions. The ground state polarization of the atom is then calculated. The same result is also obtained through linear response theory.

  4. VISCOELASTIC BEHAVIOR OF THE NON-HOOKE DEFORMATION BEFORE YIELDING IN UNIAXIAL DRAWING OF AMORPHOUS POLY(ETHYLENE TEREPHTHALATE)

    Zhen-hua Yuan; De-yan Shen; Ren-yuan Qian

    2001-01-01

    Viscoelastic behavior of the non-Hooke deformation of amorphous PET film before yield was investigated in the temperature region 74-80.5 ℃ around the glass transition temperature. The film specimen was drawn to yield point followed by unloading to zero stress, then the residual deformation was held constant, while the subsequent evolution of the stress was recorded. An induction period was found in the course of stress evolution followed by a stress step-increase. The induction period decreases with increasing drawing temperature with an activation energy of 1.10 MJ/mol @ K, which is attributed to the time needed for the relaxation of rubbery deformation through cooperative internal rotations. At temperatures lower than 74℃, there is no stress increase or the induction period becomes too long to be observed. Thus the nature of anelasticity in the non-Hooke region before yielding is attributed to stress induced rubbery deformation. The experimental results are interpreted in terms of Perez' rheological model of a series connected Hooke spring and a Voigt element consisting of a parallel connected elastic spring and a dashpot.``

    Full Text Available Abstract Background The clavicle hook plate achieves like most other operative techniques, a high percentage of union and a low percentage of complications however concerns about long term complications still exist, particularly the involvement of the acromioclavicular joint. Methods To evaluate the results and long term effects in use of this plate we performed a retrospective analysis with a mean follow up of 65 months (5.4 years of 28 consecutive patients with acute displaced lateral clavicle fractures, treated with the clavicle hook plate. Results Short term functional results in all patients were good to excellent. All but one patient had a united fracture (96%. Nine patients (32% developed impingement symptoms and in 7 patients (25% subacromial osteolysis was found. These findings resolved after plate removal. Twenty-four patients were re-evaluated at a mean follow-up period of 5.4 years. The Constant-Murley score was 97 and the DASH score was 3.5. Four patients (14% developed acromioclavicular joint arthrosis of which one was symptomatic. Three patients (11% had extra articular ossifications of which one was symptomatic. There was no relation between the impingement symptoms, subacromial osteolysis and development of acromioclavicular joint arthrosis or extra articular ossifications. Conclusions The clavicle hook plate is a good primary treatment option for the acute displaced lateral clavicle fracture with few complications. At mid term the results are excellent and no long term complications can be addressed to the use of the plate.

  6. Location of pulmonary modules prior to video thoracoscopic surgery by CT-guided hook wire placement: Preliminary study

    International Nuclear Information System (INIS)

    Despite the efficacy of computerized tomography (CT) or radiologically-guided percutaneous biopsy and that offluoroscopically-guided trans bronchial biopsy in characterizing pulmonary nodules, it is not always possible to determine the etiology using these techniques, making it necessary to resort to thoracotomy. Recent developments in endoscopicsurgery equipment and the availability of advance video imaging technology have extended the indications for both diagnostic and therapeutic thoracoscopy. Thus, a number of procedures that previously could only be performed bymeans of thoracotomy, such as resection of peripheral pulmonary nodules, can nowbe carried out by means of video thoracoscopic (VT) surgery. Palpation orvisual location of pulmonary nodules by thoracoscopy is essential but is not always possible when the nodules measure less than 20 mm or when their location is not subpleural. In such cases, a procedure for their prior location is useful. In eight patients with pulmonary nodules who were to undergo subsequent VT surgery, the attempt was made to locate the nodules by CT-guided placementof a hook wire, similar to that employed in breast, and methylene blue injection. The hook wire was correctly introduced without significant complications in all eight cases. The eight nodules were successfully resected during the thoracoscopic procedure, in which the hook wire and methylene blue staining were of great assistance. In certain cases, the location of pulmonary nodules by means of CT-guidehook wire placement and methylene blue injection allows the video thoracoscopic resection of lesions of difficult access.

    This study demonstrates unequivocally the presence of crassulacean acid metabolism (CAM) in a species of the Rubiaceae, the fourth largest angiosperm plant family. The tropical Australian endemic epiphytic ant-plant, Myrmecodia beccarii Hook.f., exhibits net CO(2) uptake in the dark and a concomitant accumulation of titratable acidity in plants in the field and in cultivation. Plants growing near Cardwell, in a north Queensland coastal seasonally dry forest of Melaleuca viridiflora Sol. ex Gaertn., accumulated ~50 % of their 24 h carbon gain in the dark during the warm wet season. During the transition from the wet season to the dry season, 24 h carbon gain was reduced whilst the proportion of carbon accumulated during the dark increased. By mid dry season many plants exhibited zero net carbon uptake over 24 h, but CO(2) uptake in the dark was observed in some plants following localised rainfall. In a shade-house experiment, droughted plants in which CO(2) uptake in the light was absent and dark CO(2) uptake was reduced, were able to return to relatively high rates of CO(2) uptake in the light and dark within 12 h of rewatering.

    This paper presents control performance evaluation of railway vehicle featured by semi-active suspension system using magnetorheological (MR) fluid damper. In order to achieve this goal, a nine degree of freedom of railway vehicle model, which includes car body and bogie, is established. The wheel-set data is loaded from measured value of railway vehicle. The MR damper system is incorporated with the governing equation of motion of the railway vehicle model which includes secondary suspension. To illustrate the effectiveness of the controlled MR dampers on suspension system of railway vehicle, the control law using the sky-ground hook controller is adopted. This controller takes into account for both vibration control of car body and increasing stability of bogie by adopting a weighting parameter between two performance requirements. The parameters appropriately determined by employing a fuzzy algorithm associated with two fuzzy variables: the lateral speed of the car body and the lateral performance of the bogie. Computer simulation results of control performances such as vibration control and stability analysis are presented in time and frequency domains.

    2015-01-01

    We present a new approach based on real time domain Feynman path integrals (RTPI) for electronic structure calculations and quantum dynamics, which includes correlations between particles exactly but within the numerical accuracy. We demonstrate that incoherent propagation by keeping the wave function real is a novel method for finding and simulation of the ground state, similar to Diffusion Monte Carlo (DMC) method, but introducing new useful tools lacking in DMC. We use 1D Hooke's atom, a two-electron system with very strong correlation, as our test case, which we solve with incoherent RTPI (iRTPI) and compare against DMC. This system provides an excellent test case due to exact solutions for some confinements and because in 1D the Coulomb singularity is stronger than in two or three dimensional space. The use of Monte Carlo grid is shown to be efficient for which we determine useful numerical parameters. Furthermore, we discuss another novel approach achieved by combining the strengths of iRTPI and DMC. We...

    The general form of interfacial contact resistance was derived for organic thin-film transistors (OTFTs) covering various injection mechanisms. Devices with a broad range of materials for contacts, semiconductors, and dielectrics were investigated and the charge injections in staggered OTFTs was found to universally follow the proposed form in the diffusion-limited case, which is signified by the mobility-dependent injection at the metal-semiconductor interfaces. Hence, real ohmic contact can hardly ever be achieved in OTFTs with low carrier concentrations and mobility, and the injection mechanisms include thermionic emission, diffusion, and surface recombination. The non-ohmic injection in OTFTs is manifested by the generally observed hook shape of the output conductance as a function of the drain field. The combined theoretical and experimental results show that interfacial contact resistance generally decreases with carrier mobility, and the injection current is probably determined by the surface recombination rate, which can be promoted by bulk-doping, contact modifications with charge injection layers and dopant layers, and dielectric engineering with high-k dielectric materials.

    Objective: To screen the anti-cancer spike-mosses for the presence of various bioactivities and to identify the important bioactive chemicals present in Selaginella inaequalifolia (S.inaequalifolia ) (Hook. & Grev.) Spring. Methods: Preliminary phytochemical screening was done by following the method of Brindha et al. Antimicrobial study was carried out by disc diffusion method. Results: Results of preliminary phytochemical screening on five different extracts (petroleum ether, benzene, chloroform, ethanol and distilled water) of the spike-mossS. inaequalifolia show the presence steroids, triterpenes, phenolic group, tannin, sugars and catechin. Alkaloids, amino acids, anthraquinone and reducing sugar did not show any positive result. Among the five different extracts, ethanol and chloroform extracts show the presence of maximum number (4 each) of compounds. The results on antimicrobial studies show that all the three microbes [Staphylococcus aureus (S. aureus), Escherichia coli (E. coli) and Candida albicans(C. albicans) ] tested are resistant to the ethanol extract and susceptible to petroleum ether extract. The petroleum ether extract shows maximum inhibition with 45 mm of inhibition zone in C. albicans. The inhibition zone in S. aureus and E. coli are 26 mm and 22 mm respectively. Conclusions: The present study shows S. inaequalifolia having potent antibacterial and anticandidal activities.

  14. Compressive Behavior of Fiber-Reinforced Concrete with End-Hooked Steel Fibers

    Seong-Cheol Lee

    2015-03-01

    Full Text Available In this paper, the compressive behavior of fiber-reinforced concrete with end-hooked steel fibers has been investigated through a uniaxial compression test in which the variables were concrete compressive strength, fiber volumetric ratio, and fiber aspect ratio (length to diameter. In order to minimize the effect of specimen size on fiber distribution, 48 cylinder specimens 150 mm in diameter and 300 mm in height were prepared and then subjected to uniaxial compression. From the test results, it was shown that steel fiber-reinforced concrete (SFRC specimens exhibited ductile behavior after reaching their compressive strength. It was also shown that the strain at the compressive strength generally increased along with an increase in the fiber volumetric ratio and fiber aspect ratio, while the elastic modulus decreased. With consideration for the effect of steel fibers, a model for the stress–strain relationship of SFRC under compression is proposed here. Simple formulae to predict the strain at the compressive strength and the elastic modulus of SFRC were developed as well. The proposed model and formulae will be useful for realistic predictions of the structural behavior of SFRC members or structures.

    Full Text Available Burahol (Stelechocarpus burahol (Blume Hook & Thomson is one of fruit tree that originally was founded in Indonesia. Traditionally burahol is used as natural deodorance, but due to low economic value, the cultivation program of this plant species is almost abandoned. Regarding to this situation, currently this plant species could be categorized as one of endangered species. At present, economic value of this fruit is almost neglected and this is the main reason why not many people interested to cultivate this plant. In order to change the people opinion on this plant and to improve it economic value, study on the chemical content of this plant had been carried out. From the research work, it was founded that burahol fruit have a significant content of anti-oxidative compound. From the anti-oxidative analysis using DPPH (1,1-diphinil pycril hidrazil method, the lowest IC50 was showed by n-buthanol extract of flower (22.44 ppm and ethyl acetate extract of fruit (29.12 ppm. Flower part also showed low IC50 of ethyl acetate extract (35.07 ppm. Further purification through fractionation process of the plant extract was surprisingly followed by the decrease of anti-oxidative activity.

    Full Text Available Dyera costulata (Miq. Hook.f (Apocynaceae is a large tree of the lowland tropical rain forest of Southeast Asia, Thailand, Malay Peninsula and Indonesia, especially in Sumatra and Kalimantan (Borneo islands. Its economic value was in its copious latex, used as gum in the manufacture of chewing gum. Today the timber of this species is much sought after for the manufacture of pencils and picture frames. Information on genetic diversity of the species is very limited. Hence studies were initiated to screen primers for RAPD analyses of Dyera costulata for use in genetic variation studies. Seventy one Operon primers (10 mer were used to generate a total of 864 consistent and ambiguous amplification products ranging from 200 bp to 2.0 kb. Rare and genotype specific bands were identified which could be effectively used to distinguish the genotypes. 34 highly polymorphic primers (100% are recorded from 71 primers used. Three primers (OPA-04, OPU-06, and OPU-07 produced highest variable RAPD profiles. The dendrogram separated the 8 genotypes into 2 groups. Genetic dissimilarity ranged from 0.07 to 0.71 %.

    The formation mechanism for blue hook (BHk) stars in globular clusters (GCs) is still unclear. Following one of the possible scenario, named late hot flash scenario, we proposed that tidally enhanced stellar wind in binary evolution may provide the huge mass loss on the red giant branch (RGB) and produce BHk stars. Employing the detailed stellar evolution code, Modules for Experiments in Stellar Astrophysics (MESA), we investigated the contributions of tidally enhanced stellar wind as a possible formation channel for BHk stars in GCs. We evolved the primary stars with different initial orbital periods using the binary module in MESA (version 6208) from zero age main-sequence (ZAMS) to post horizontal branch (HB) stage, and obtained their evolution parameters which are compared with the observation. The results are consistent with observation in the color-magnitude diagram (CMD) and the logg-Teff plane for NGC 2808, which is an example GC hosting BHk stars. However, the helium abundance in the surface for our ...

    Full Text Available A protocol is described for rapid and large scale propagation of an endangered, important Sikkim Himalayan rhododendron (R. maddeni Hook. f. by in vitro culture of cotyledonary nodes from 15 days old seedlings. Several cytokinin types were evaluated for their effect on shoot multiplication from cotyledonary nodes. Maximum numbers of shoot (12.00 �0.58 were observed on the AM containing 7 mg/l 2iP, 0.1 mg/l IAA after eight weeks of culture. Incorporation of 0.1 mg/l IAA in the medium during the first subculture after establishment and initiation of shoot buds significantly improved the shoot elongation. Regenerated shoots were separated and rooted on same strength AM medium supplemented with 0.2 mg/l of IBA alone for three weeks. Well-developed complete plantlets were transferred on to specially made plastic cup containing soilrite. The rooted plantlets were hardened and successfully established in greenhouse, the plants were transferred to field site at Pangthang arboretum of the Institute and the �Rare & Threatened Plant Conservation Park� of Zoological Park, Gangtok, Sikkim.

    Full Text Available Plants engineered with genes encoding for the antigenic proteins of various microorganisms have shown to correctly express the proteins that elicit the production of antibodies in mammalian hosts. In livestock, plant-based vaccines could represent an innovative strategy for oral vaccination, especially to prevent infection by enteric pathogens. The aim of this study was to evaluate tobacco plants as a seedspecific expression system for the production of the flgK flagellar hook-associated protein from a wild type Salmonella typhimurium strain, as a model of an edible vaccine. The flgK gene is the principal component of bacterial flagella and is recognised as virulence factor by the innate immune system. It was isolated from the Salmonella typhimurium strain by PCR. The encoding sequence of flgK was transferred into a pBI binary vector, under control of soybean basic 7S globulin promoter for the seed-specific. Plant transformation was carried out using recombinant EHA 105 Agrobacterium tumefaciens. A transgenic population was obtained made up of independently kanamycin-resistant transgenic plants, which had a similar morphological appearance to the wild-type plants. Molecular analyses of seeds confirmed the integration of the gene and the average expression level of flgK was estimated to be about 0.6 mg per gram of seeds, corresponding to 0.33% of the total amount of soluble protein in tobacco seeds. This study showed that the foreign flgK gene could be stably incorporated into the tobacco plant genome by transcription through the nuclear apparatus of the plant, and that these genes are inherited by the next generation.

    Tinospora crispa (L.) Hook. f. & Thomson (Menispermaceae), found in the rainforests or mixed deciduous forests in Asia and Africa, is used in traditional medicines to treat numerous health conditions. This review summarizes the up-to-date reports about the ethnobotany, phytochemistry, pharmacological activities, toxicology, and clinical trials of the plant. It also provides critical assessment about the present knowledge of the plant which could contribute toward improving its prospect as a source of lead molecules for drug discovery. The plant has been used traditionally in the treatment of jaundice, rheumatism, urinary disorders, fever, malaria, diabetes, internal inflammation, fracture, scabies, hypertension, reducing thirst, increasing appetite, cooling down the body temperature, and maintaining good health. Phytochemical analyses of T. crispa revealed the presence of alkaloids, flavonoids, and flavone glycosides, triterpenes, diterpenes and diterpene glycosides, cis clerodane-type furanoditerpenoids, lactones, sterols, lignans, and nucleosides. Studies showed that the crude extracts and isolated compounds of T. crispa possessed a broad range of pharmacological activities such as anti-inflammatory, antioxidant, immunomodulatory, cytotoxic, antimalarial, cardioprotective, and anti-diabetic activities. Most pharmacological studies were based on crude extracts of the plant and the bioactive compounds responsible for the bioactivities have not been well identified. Further investigations are required to transform the experience-based claims on the use of T. crispa in traditional medicine practices into evidence-based information. The plant extract used in pharmacological and biological studies should be qualitatively and quantitatively analyzed based on its biomarkers. There should be detail in vitro and in vivo studies on the mechanisms of action of the pure bioactive compounds and more elaborate toxicity study to ensure safety of the plant for human use. More

    Famous Foreign Scholars' Lecture Tours in China Around the May Fourth Movement and Changes in Chinese Intellectual Circles From 1919 to 1924, John Dewey and four other famous foreign scholars came to China on lecture tours. These tours were great cultural undertakings to spread Western learning to the East after the First World War. The lectures these schol- ars gave helped to deepen the thoughts of Chinese people, and at the same time encouraged the diversification and evolution of Chinese intellectual circles. Firstly, the lectures hastened the birth of a contemporary Chinese wave of reflection on mo- dernity, and provided a basis for the theoretical views and cultural appeals of Liang Qichao and other members of the socalled "Orient Culture Faction," thereby increasing the tension intrinsic to the development of the New Culture Movement and to the expansion of intellectual horizons in Chinese intellectual circles.

    Full Text Available In recent years, some of China’s leading firms have made headlines with their European expansion, by either opening new facilities or by acquiring or merging with significant enterprises in Europe. The goal of this paper is to contribute to the existing literature by examining Chinese enterprises expanding into Switzerland. The study also allows some conclusions for Chinese companies entering Central and Eastern Europe. We analyze via interviews the motivations of Chinese companies to expand into Switzerland as well as their behavior and the impediments in their internationalization process. Our findings show that Chinese companies fail to take advantage of certain benefits of western economies (such as open information and stable rule of law. To move forward efficiently, they should develop competence in dealing systematically with readily available market information, building professional networks that recognize a separation between business life and personal life, and managing their Chinese and foreign employees in the foreign cultural environment.

    Chinese parody, as a traditional figure of speech, has captured more and more attention from scholars. The researches conducted up to date are inadequate in theorizing and exploring its translation. This paper, based on the comparative data analysis of Chinese parody translation examples in different types of texts, attempts to probe into the means about how to achieve the clos⁃est function equivalence in rendering Chinese parody under the guidance of Sociosemiotic Approach. It is found that the nature of Chinese parody translation is to achieve the closest natural equivalence or similarity in expressive function, informative func⁃tion, vocative function and aesthetic function in its equivalents in English. And it is suggested that borrowing, imitating, para⁃phrasing and adapting are effective strategies in translating Chinese parody.

    Psiloxylon mauritianum (PM) (Bouton ex Hook.f.) Baillon (Myrtaceae) is an evergreen endemic medicinal plant which has shown promising uses in traditional medicine from the Mascarene Islands (Mauritius and Réunion Islands). Folk use of this endemic plant in Mauritius and Réunion Islands has been geared toward the treatment and management of amenorrhea, dysentery and Type II diabetes mellitus. Recent findings from in vitro studies have led to the discovery of two potent acids namely corosolic acid and asiatic acid which have been shown to bear most inhibitory activities against Staphylococcus aureus. Such findings tend to appraise the therapeutic potential of this medicinal plant against infectious diseases. The present monograph has tried to establish the botanical description, traditional uses and the main constituents identified from PM (Bouton ex Hook.f.) Baillon. The limited documentation of in vitro assays of this plant demonstrates an urgent need for extensive research in order to validate other traditional uses and hence open new avenues for drug development.

    Full Text Available Background. Paediatric emotional and behavioural disorders (EBD are relatively common diseases. Although nonpharmacologic and pharmacologic treatments are utilized in these cases, it is sometimes difficult to manage the symptoms of EBD. Historically, Uncaria hook has been used for treating nighttime crying and convulsions in children. Recent clinical studies have demonstrated that the Kampo medicine Yokukansan (YKS, which contains Uncaria hook, is efficacious for behaviour disorders in Alzheimer’s disease patients. Herein, we investigated the clinical efficacy and safety of YKS in a series of cases with paediatric EBD. Patients and Methods. We retrospectively reviewed all paediatric patients who sought Japanese Kampo therapy at our outpatient clinics between April 1, 2012, and April 30, 2013; we selected patients who were diagnosed with paediatric EBD and were treated with YKS. Results. After screening all candidates, 3 patients were eligible for this analysis. Their average age was 11.6 years (range 10–13 years. All 3 patients responded very well to YKS within 1 month. No drug-related adverse events were observed during the course of YKS treatment. Conclusion. Yokukansan may be efficacious for paediatric EBD. We believe these results warrant further evaluation of the clinical efficacy and safety of Yokukansan for paediatric EBD in a carefully designed, double-blind, randomized clinical study.

    New Caledonian crows are renowned for their unusually sophisticated tool behaviour. Despite decades of fieldwork, however, very little is known about how they make and use their foraging tools in the wild, which is largely owing to the difficulties in observing these shy forest birds. To obtain first estimates of activity budgets, as well as close-up observations of tool-assisted foraging, we equipped 19 wild crows with self-developed miniature video cameras, yielding more than 10 h of analysable video footage for 10 subjects. While only four crows used tools during recording sessions, they did so extensively: across all 10 birds, we conservatively estimate that tool-related behaviour occurred in 3% of total observation time, and accounted for 19% of all foraging behaviour. Our video-loggers provided first footage of crows manufacturing, and using, one of their most complex tool types--hooked stick tools--under completely natural foraging conditions. We recorded manufacture from live branches of paperbark (Melaleuca sp.) and another tree species (thought to be Acacia spirorbis), and deployment of tools in a range of contexts, including on the forest floor. Taken together, our video recordings reveal an 'expanded' foraging niche for hooked stick tools, and highlight more generally how crows routinely switch between tool- and bill-assisted foraging.

  2. Influencing mechanism of Zn interlayer addition on hook defects of friction stir spot welded Mg–Al–Zn alloy joints

    International Nuclear Information System (INIS)

    Highlights: • Mg–Al–Zn sheets were friction stir spot welded (FSSW) with addition of Zn interlayer. • Complex alloying reactions occurred between Mg sheets and Zn interlayer during FSSW. • Alloying reactions increased the area of bonded zone and eliminated the hook defects. • Tensile–shear load of FSSW joints increased from 2.4 to 4 kN by adding Zn interlayer. - Abstract: 2.4 mm thick Mg–Al–Zn alloy sheets were friction stir spot welded (FSSW) without and with the addition of 0.1 mm thick Zn interlayer. The influence of interlayer addition on the microstructural features and mechanical properties of FSSW joints was investigated by optical microscope, scanning electron microscope, transmission electron microscope, X-ray diffraction and tensile testing. The results show that the addition of Zn interlayer resulted in complex alloying reactions between Mg substrate and Zn interlayer, forming a bonded zone composed of α-Mg, (α-Mg + MgZn) eutectoid structure and a mixture of Mg4Zn7 and unreacted Zn, thereby increasing the area of bonded zone and reducing the hook defects. This results in a significant increase in tensile–shear load from 2.4 kN to about 4 kN

    The earliest industrial biotechnology originated in ancient China and developed into a vibrant industry in traditional Chinese liquor, rice wine, soy sauce, and vinegar. It is now a significant component of the Chinese economy valued annually at about 150 billion RMB. Although the production methods had existed and remained basically unchanged for centuries, modern developments in biotechnology and related fields in the last decades have greatly impacted on these industries and led to numerous technological innovations. In this chapter, the main biochemical processes and related technological innovations in traditional Chinese biotechnology are illustrated with recent advances in functional microbiology, microbial ecology, solid-state fermentation, enzymology, chemistry of impact flavor compounds, and improvements made to relevant traditional industrial facilities. Recent biotechnological advances in making Chinese liquor, rice wine, soy sauce, and vinegar are reviewed. PMID:19888561

    Full Text Available The thunder god vine or Tripterygium wilfordii Hook. F. is a representative Chinese medicinal herb which has been used widely and successfully for centuries in treating inflammatory diseases. More than 100 components have been isolated from this plant, and most of them have potent therapeutic efficacy for a variety of autoimmune and inflammatory diseases. In the past four decades, the anticancer activities of the extracts from this medicinal herb have attracted intensive attention by researchers worldwide. The diterpenoid epoxide triptolide and the quinone triterpene celastrol are two important bioactive ingredients that show a divergent therapeutic profile and can perturb multiple signal pathways. Both compounds promise to turn traditional medicines into modern drugs. In this review, we will mainly address the anticancer activities and mechanisms of action of these two agents and briefly describe some other antitumor components of the thunder god vine.

    Full Text Available Direct ear trauma through external auditory canal causing an avulsion injury of malleoincudal complex is a grievous injury that can happen during ear cleaning with indigenous ear hook. One such case of avulsion injury is presented here with its symptomatology, investigation, and management with the review of available literature because of its rarity. Various locally designed indigenous ear hooks are available in street side markets and even online for purchase and used by many without knowing its ill effects on health. Injury caused by these types of hooks may lead to a severe hearing disability, if not properly treated. This presentation is to highlight the fact that indigenous ear hooks; rampantly available online for purchase can cause a potentially major injury leading to hearing disability and thereafter poor quality of life. Reporting and highlighting of such incidents among the ENT community can help increase the public awareness; thereby, eliminating such disastrous consequences. Wikipedia, PubMed, and Google search engine has been used for our data collection and analysis.

    2001-01-01

    In a series of laboratory studies designed to simulate bycatch processes, sablefish Anoplopoma fimbria were either hooked for up to 24 h or towed in a net for 4 h and then subjected to an abrupt transfer to elevated sea water temperature and air. Mortality did not result from hooking or net towing followed by exposure to air, but increased for both capture methods as fish were exposed to elevated temperatures, reflecting the magnifying effect of elevated temperature on mortality. Hooking and exposure to air resulted in increased plasma cortisol and lactate concentrations, while the combination of hooking and exposure to elevated temperature and air resulted in increased lactate and potassium concentrations. In fish that were towed in a net and exposed to air, cortisol, lactate, potassium and sodium concentrations increased, but when subjected to elevated temperature and air, no further increases occurred above the concentrations induced by net towing and air, suggesting a possible maximum of the physiological stress response. The results suggest that caution should be exercised when using physiological measures to quantify stress induced by capture and exposure to elevated temperature and air, that ultimately result in mortality, since the connections between physiological stress and mortality in bycatch processes remain to be fully understood.

    Eucalyptus citriodora Hook. is highly valued for its citronellal-rich essential oil (EO) extracted from its leaves. Hence, escalated EO production of eucalyptus is the need of hour. Marine polysaccharides (sodium alginate) are processed through gamma radiation of particular intensity, to obtain the irradiated sodium alginate (ISA). A pot experiment was conducted to study the effect of foliar application of ISA on growth, biochemical, physiological, EO yield and composition of E. citriodora. The treatments were applied as: foliar spray of deionized water only (control), seed soaked with ISA (90 mg L(-1)) and foliar spray of ISA with 30, 60, 120 and 240 mg L(-1). The treatment 6 (spray of ISA at 120 mg L(-1)) showed the highest value for most of the parameters studied. It also enhanced the EO content (33.3%), EO yield (86.7%), citronellal content (63.4%) and citronellal yield (205.5%) as compared to the control. PMID:25129727

    Multiple shoots were obtained from terminal buds of 20-year-old trees of Eucalyptus citriodora Hook on Murashige and Skoog's medium supplemented with calcium pantothenate, biotin, benzylaminopurine and kinetin. Rooting could be induced by naphthalene-acetic acid in shoot cultures only after they had undergone three subcultures. Incubation at 15/sup 0/C with continuous illumination followed by growth in agitated liquid cultures was essential for inducing shoot development in the primary terminal buds. These treatments were not necessary in later subcultures or with explants from seedlings obtained from seeds. Fifteen subcultures have so far been carried out and healthy viable plantlets obtained in each subculture. It is estimated that over 100,000 plants can be obtained by this method in a year from a single bud of mature Eucalyptus citriodora trees.

    In vitro mass production of C. suaveolens (Lindl.) Hook, an endangered orchid with its snowy white flowers having horticultural potential was accomplished through immature seed culture, and subsequent plant regeneration. The developmental stage of the immature seeds and nutrient media significantly influenced the germination frequency. Seeds at 13 months after pollination cultured on 3% sucrose containing Murashige and Skoog (MS) medium with 9 microM alpha-naphthaleneacetic acid (NAA), and 15% coconut water exhibited 93% germination after 40 days of culture. Upon subculture, the germinated shoots on MS medium with 9 microM BA, 6 microM NAA, 3% casein hydrolysate and 0.1% activated charcoal (AC) yielded >12 shoots per shoot or bud. Addition of AC favoured the enlargement of pseudobulbs and better rooting. The plantlets transferred to community potting mix after in vitro hardening (8-10 wk) displayed 85% survival. PMID:18512333

    Full Text Available Ambient ionization mass spectrometric imaging of all parts of the seedling of Dysoxylum binectariferum Hook. f (Meliaceae was performed to reconstruct the molecular distribution of rohitukine (Rh and related compounds. The species accumulates Rh, a prominent chromone alkaloid, in its seeds, fruits, and stem bark. Rh possesses anti-inflammatory, anti-cancer, and immuno-modulatory properties. Desorption electrospray ionization mass spectrometry imaging (DESI MSI and electrospray ionization (ESI tandem mass spectrometry (MS/MS analysis detected Rh as well as its glycosylated, acetylated, oxidized, and methoxylated analogues. Rh was predominantly distributed in the main roots, collar region of the stem, and young leaves. In the stem and roots, Rh was primarily restricted to the cortex region. The identities of the metabolites were assigned based on both the fragmentation patterns and exact mass analyses. We discuss these results, with specific reference to the possible pathways of Rh biosynthesis and translocation during seedling development in D. binectariferum.

  11. Antigen binding in the two-site immunoradiometric assay for serum ferritin: the nature of the hook effect

    International Nuclear Information System (INIS)

    The two stages of a two-site immunoradiometric assay were investigated separately. In the first stage, the amount of ferritin bound to coated tubes initially showed a rapid increase with increasing concentration of added ferritin. This was followed by a plateau and than a further increase which appeared to be largely due to non-specific binding. During the second stage, a significant proportion of the bound ferritin dissociated from the solid phase and sequestered some of the labelled antibody in solution. Thus less antibody was available to bind to ferritin attached to the tube, causing a decrease in count rate at high ferritin concentrations. The use of a monoclonal antibody for coating the tubes did not eliminate this hook effect. (author)

This was managed laparoscopically using monopolar diathermy hook with conservation of the ovary and minimal blood loss. Ovarian pregnancy is rare, especially in women without the classical risk factors for tubal pregnancy, and efforts should be made to exclude ectopic pregnancy in the absence of abdominal pain in a woman of reproductive age presenting with prolonged and irregular vaginal bleeding. Methods to conserve the ovary are also encouraged in cases of ovarian pregnancy.

  18. Knowing Chinese character grammar.

    Science.gov (United States)

    Myers, James

    2016-02-01

    Chinese character structure has often been described as representing a kind of grammar, but the notion of character grammar has hardly been explored. Patterns in character element reduplication are particularly grammar-like, displaying discrete combinatoriality, binarity, phonology-like final prominence, and potentially the need for symbolic rules (X→XX). To test knowledge of these patterns, Chinese readers were asked to judge the acceptability of fake characters varying both in grammaticality (obeying or violating reduplication constraints) and in lexicality (of the reduplicative configurations). While lexical knowledge was important (lexicality improved acceptability and grammatical configurations were accepted more quickly when also lexical), grammatical knowledge was important as well, with grammaticality improving acceptability equally for lexical and nonlexical configurations. Acceptability was also higher for more frequent reduplicative elements, suggesting that the reduplicative configurations were decomposed. Chinese characters present an as-yet untapped resource for exploring fundamental questions about the nature of the human capacity for grammar. PMID:26684059

The low survival rate of sea horse juvenile due to low food intake slowed down the development of the culture industry; however, the reasons that impact feeding behavior and its metabolism of the juvenile are unclear. To address this, ten 2- or 3-day-old juveniles ofHippocampus kudawerefixed in paraformaldehyde with PBS, and its skeletal morphology of the snout tube was observed and analyzed. The tube snout’s profile and structure included metapterygoid, quadrate and symplectic, were important to juvenile’s feeding. A hole composed of metapterygoid and the end of symplectic is the smallest diameter in the snout tube, which decided the size of the feeding food. In addition, there is a crevice between metapterygoid and symplectic, which could slightly compensate the limitation in the snout tube and can pass bigger food than the smallest diameter. These observations suggest that properly increasing the size of food might enhance feeding efficiency and promote survival rate.

    Full Text Available China may be on the tipping point of explosive global growth. In response to changes in the global economy and an economic slowdown domestically, hundreds of thousands of Chinese SMEs are being encouraged to “go global” by their central and local governments. To a Chinese company, going global requires the expansion of its existing business in other countries or the development of new ventures with partners operating in other countries. Explosive growth in China may be possible, but it will depend on an appropriate strategy for going global. For a country that has firmly established itself as an international manufacturing hub, going global requires a shift in its entrepreneurial capacity, which is the focus of this article. We first assess the current situation in China to understand its current entrepreneurial focus and capacity, as well as the impetus for change. Next, we contrast the Kirznerian and Schumpeterian views of entrepreneurship to illustrate that – to go global – Chinese entrepreneurs must shift from an emphasis on exploiting pricing inefficiencies (i.e., Kirznerian entrepreneurship to an emphasis on innovation (i.e., Schumpeterian entrepreneurship. Finally, we examine unique characteristics of the business environment and culture in China, which are likely to impact the ability of Chinese entrepreneurs to go global.

  18. What can numerical computation do for the history of science? (a study of an orbit drawn by Newton in a letter to Hooke)

    International Nuclear Information System (INIS)

    In a letter to Robert Hooke, Isaac Newton drew the orbit of a mass moving under a constant attracting central force. The drawing of the orbit may indicate how and when Newton developed dynamic categories. Some historians claim that Newton used a method contrived by Hooke; others that he used some method of curvature. We prove that Hooke’s method is a second-order symplectic area-preserving algorithm, and the method of curvature is a first-order algorithm without special features; then we integrate the Hamiltonian equations. Integration by the method of curvature can also be done, exploring the geometric properties of curves. We compare three methods: Hooke’s method, the method of curvature and a first-order method. A fourth-order algorithm sets a standard of comparison. We analyze which of these methods best explains Newton’s drawing. (paper)

    This study details an innovative and methodical content analysis of 2,207 YouTube comments from four different YouTube videos (e.g., breaking news or memorials) related to the 2012 Sandy Hook Elementary School and Aurora theater mass shootings and the catastrophic Hurricane Sandy. As expected, YouTube comments associated with the Sandy Hook shootings (particularly those from a memorial video) were especially likely to feature compassion and grief with lessened hostility. This study highlights differing online contexts by which individuals show grief and related emotions following man-made and natural calamities and how-even in an online environment-powerful situational contexts greatly guide behavior.

    The Pan-African Hook Batholith formed during the assembly of the Gondwana supercontinent between 570 and 520 Ma (U-Pb on zircon) as a result of syn-collisional stage interaction between the Congo and Kalahari Cratons1. The extension of the batholith, exposed and undercover, is estimated to be between 25,000 and 30,000 km2. The bimodal magmatism (mafic to predominantly felsic) is characterized by both an alkali-calcic and an alkalic suite, with the felsic rocks featuring a typical A-type, metaluminous, high Fe/Mg and K/Na geochemical signature. The scattered outcrops of gabbroic rocks, both tholeiitic and alkaline, suggest periodic input of mantle material, which, in some cases, interacted with metasomatizing fluids. Fractional crystallization is invoked for the most differentiated products, while Sr-Nd isotopes rule out any significant contribution from crustal assimilation. Exceptionally highly radiogenic Pb isotopes have been measured on both unaltered and hydrothermally altered rocks, and attest to the radiogenic character of the batholith. The Pb isotopes indicate that the anomalous signature was acquired during, or soon after, magma emplacement, and was likely enhanced by metasomatizing fluids. An enrichment in Th and U, affecting large portions of the crust along the southern margin of the Congo Craton, is suggested by comparable anomalous Pb isotopes measured in basement gneisses in the Domes Region, Zambian Copperbelt. Geochemical and isotopic evidence support interaction between mantle components and portions of the deep crust at pressures of rocks along the eastern margin of the pluton indicate that the magma was subsequently emplaced at shallow crustal depths. A crucial contribution to the crustal melting was likely provided by internal radiogenic heat production of the thickened crust, and is in agreement with the high radioactivity of the pluton. A tectono-thermal model where crustal accretion is accompanied by slab retreat and lithospheric mantle

  1. Kinematic, dynamic, and thermodynamic impacts of hook-echo hydrometeors, including explorations into the utilization of polarimetric radar data

    Science.gov (United States)

    Askelson, Mark Anthony

    Recent studies have revealed that the thermodynamic properties of the rear flank downdraft (RFD) may dictate whether or not a supercell becomes tornadic. Since hydrometeors are thought to be an important driving force for the RFD, it is postulated that they may be important to its thermodynamic properties and, possibly, to tornadogenesis. The role hook-echo hydrometeors play in driving RFDs is investigated by estimating hook-echo hydrometeor types and amounts from polarimetric radar data and by using that information to drive a relatively simple downdraft model. Soundings for the individual cases are used to initialize the downdraft model in order to replicate the environments of the storms as closely as possible. Since this effort and others like it require the quantitative utilization of radar data, issues pertaining to this are explored. In addition to analyses of coordinate transformation equations and an innovative objective analysis technique for weather radar data, the difficult problem of response functions for arbitrary weight functions and data distributions was considered. A novel approach to this problem revealed that the local response function for distance dependent weighted averaging schemes is the complex conjugate of the normalized Fourier transform of the effective weight function. This facilitates new research avenues, especially regarding analyses of irregularly spaced data. Simulations of hydrometeor driven RFDs show that hydrometeor fields inferred from radar data are able to drive significant downdrafts without the influence of vertical perturbation pressure gradients. Moreover, they reveal that above the boundary layer supercell environments are relatively resistant to downdrafts whereas within the boundary layer they are generally supportive of downdrafts. It appears that in many supercell environments relatively large hail (≥1 cm in diameter) or vertical perturbation pressure gradients may be needed to drive deep midlevel downdrafts that

    Full Text Available Abstract Acromioclavicular joint dislocations often occur in athletic, young patients after blunt force to the shoulder. Several static and dynamic operative procedures with or without primary ligament replacement have been described. Between February 2003 and March 2009 we treated 313 patients suffering from Rockwood III-V lesions of the AC joint with an AC-hook plate. 225 (72% of these patients could be followed up. Mean operation time was 42 minutes in the conventional group and 47 minutes in the minimal invasive group. The postoperative pain on a scale from 1 to 10 (VAS-scale was rated 2.7 in the conventional group and 2.2 in the minimal invasive group. Taft score showed very good and good results in 189 patients (84%. Constant score showed an average of 92.4 of 100 possible points with 89% excellent and good results and 11% satisfying results. All patients had some degree of pain or discomfort with the hookplate in place. These symptoms were relieved after removal of the plate. The overall complication rate was 10.6%. There were 6 superficial soft tissue infections, 1 fracture of the acromion, 7 redislocations after removal of the hook-plate. We observed 4 broken hooks which could be removed at the time of plate removal, 4 seromas and 2 cases of lateral clavicle bone infection, which required early removal of the plate. We can conclude that clavicle hook plate is a convenient device for the surgical treatment of Rockwood Grade III-V dislocations, giving good mid-term results with a low overall complication rate compared to the literature. Early functional therapy is possible and can avoid limitations in postoperative shoulder function.

    To retrospectively evaluate the safety of computed tomography (CT) fluoroscopy-guided short hook wire placement for video-assisted thoracoscopic surgery and the risk factors for pneumothorax associated with this procedure. We analyzed 267 short hook wire placements for 267 pulmonary lesions (mean diameter, 9.9 mm). Multiple variables related to the patients, lesions, and procedures were assessed to determine the risk factors for pneumothorax. Complications (219 grade 1 and 4 grade 2 adverse events) occurred in 196 procedures. No grade 3 or above adverse events were observed. Univariate analysis revealed increased vital capacity (odds ratio [OR], 1.518; P = 0.021), lower lobe lesion (OR, 2.343; P = 0.001), solid lesion (OR, 1.845; P = 0.014), prone positioning (OR, 1.793; P = 0.021), transfissural approach (OR, 11.941; P = 0.017), and longer procedure time (OR, 1.036; P = 0.038) were significant predictors of pneumothorax. Multivariate analysis revealed only the transfissural approach (OR, 12.171; P = 0.018) and a longer procedure time (OR, 1.048; P = 0.012) as significant independent predictors. Complications related to CT fluoroscopy-guided preoperative short hook wire placement often occurred, but all complications were minor. A transfissural approach and longer procedure time were significant independent predictors of pneumothorax. (orig.)

    Interactions between the nuclear matrix and special regions of chromosomal DNA called matrix attachment regions (MARs) have been implicated in various nuclear functions. We have identified a novel protein from wheat, AT hook-containing MAR binding protein1 (AHM1), that binds preferentially to MARs. A multidomain protein, AHM1 has the special combination of a J domain-homologous region and a Zn finger-like motif (a J-Z array) and an AT hook. For MAR binding, the AT hook at the C terminus was essential, and an internal portion containing the Zn finger-like motif was additionally required in vivo. AHM1 was found in the nuclear matrix fraction and was localized in the nucleoplasm. AHM1 fused to green fluorescent protein had a speckled distribution pattern inside the nucleus. AHM1 is most likely a nuclear matrix component that functions between intranuclear framework and MARs. J-Z arrays can be found in a group of (hypothetical) proteins in plants, which may share some functions, presumably to recruit specific Hsp70 partners as co-chaperones. PMID:11041885

    In case of patients with spinal cord injury and concomitant acromioclavicular (AC) joint-dislocation the treatment is challenging, as in this special patient group the function of the shoulder joint is critical because patients depend on the upper limb for mobilization and wheelchair-locomotion. Therefore the goal of this study was to examine, if the treatment of chronic AC-joint dislocation using the Weaver-Dunn procedure augmented with a hook-plate in patients with a spinal cord injury makes early postoperative wheelchair mobilization and the wheelchair transfer with full weight-bearing possible. In this case the Weaver-Dunn procedure with an additive hook-plate was performed in a 34-year-old male patient with a complete paraplegia and a posttraumatic chronic AC-joint dislocation. The patient was allowed to perform his wheelchair transfers with full weight bearing on the first post-operative day. The removal of the hook-plate was performed four months after implantation. At the time of follow-up the patient could use his operated shoulder with full range of motion without restrictions in his activities of daily living or his wheel-chair transfers. PMID:27433301

    Triptophenolide and its related compounds from Tripterygium wilfordii Hook.f is a kind of diterpenoids which shows anti-inflammatory activity. To study the metabolites of triptophenolide related compounds, the fragmentation mechanisms of them were investigated by using negative electrospray tandem mass spectrometry. With the aid of high resolution of ESI-QTOF-MS/MS, the fragmentation mechanisms of six diterpenoid compounds were systematically investigated. The fragmentation behavior mainly depends on what substituent groups the benzyl C ring bears. If there is a hydroxyl group on the position of C14, loss of CH4 is dominating. However, the successive loss of two CH3 radicals is predominant when the hydroxyl group of O14 is methylated. The lactone ring is prone to be dissociated to loss of CO, CO2 and C2H2O2 molecules. The pericyclic reaction can occur on A ring if there is an active hydrogen resides on C ring. Furthermore, one metabolite of compound A1 was confirmed by cytochrome P450 in vitro and the structure was proposed by tandem mass experiment together with the fragmentation mechanisms of this type of compounds.

    Science.gov (United States)

    Arnol'D, V. I.

    This book is an English translation of the Russian original of 1989. It is based on a college lecture commemorating the tercentenary of Newton's book Philosophiae Naturalis Principia Mathematica. The author retraces the beginnings of mathematical analysis and theoretical physics in the works of the great scientists of the 17th century, and recounts the history of the discovery of the law of gravitation, discussions Newton had with Hooke and Leibniz, and much more. Some of Huygens' and Newton's ideas, several centuries ahead of their time, were developed only recently. The author follows the link between their inception and the break-throughs in contemporary mathematics and physics. The book provides present-day generalizations of Newton's theorems on the elliptical shape of orbits, attraction of spheres, and on the transcendence of Abelian integrals; it offers a brief review of the theory of regular and chaotic movement in celestial mechanics, including, for example, the problem of ports in the distribution of smaller planets and a discussion of the structure of planetary rings.

    A begomovirus isolate VN1 associated with symptomatic Hedyotis uncinella Hook. et Arn. from Vietnam was characterized. The virus, which we provisionally name H. uncinella yellow mosaic virus (HUYMV), has a monopartite genome of 2,749 nucleotides (nts). Pairwise comparisons of DNA-A sequences showed that HUYMV had a maximum nt sequence identity with Soybean crinkle leaf virus (SbLCV) and Premna leaf curl virus (PLCuV) at 82.1 and 81.9 %, respectively, which are less than the 89 % identity in the complete genome, which has been used as the threshold value for demarcation of species in the genus Begomovirus, the family Geminiviridae. One recombination event was detected for HUYMV, which involves an unknown begomovirus as the major parent and Tomato leaf curl Philippines virus (ToLCPV) as the minor parent, with nt 2163 and nt 2452 as the beginning and ending breakpoints, respectively. A betasatellite was found to be associated with HUYMV. The betasatellite showed the highest nt sequence identity (70 %) with Tomato leaf curl Philippine betasatellite--[Philippines:Laguna2:2006]. The name H. uncinella yellow mosaic betasatellite [Vietnam: Binh Dinh: 2013] was proposed for the betasatellite. PMID:24510306

    Full Text Available This study investigates the potential of satellite altimetry for water level time series estimation of smaller inland waters where only very few measurements above the water surface are available. A new method was developed using off-nadir measurements to estimate the parabola generated by the hooking effect. For this purpose, a new waveform retracker was used as well as an adopted version of the RANdom SAmple Consensus (RANSAC algorithm. The method is applied to compute time series of the water levels height of the Mekong River and some of its tributaries from Envisat high-frequency data. Reliable time series can be obtained from river crossings with widths of less than 500 m and without direct nadir measurements over the water. The expected annual variations are clearly depicted and the time series well agree with available in situ gauging data. The mean RMS value is 1.22 m between the resulting time series and in situ data, the best result is 0.34 m, the worst 2.26 m, and 80% of the time series have an RMS below 1.5 m.

    Full Text Available The uncultivated Ca. Altiarchaeum hamiconexum (formerly known as SM1 Euryarchaeon carries highly specialized nano-grappling hooks (hami on its cell surface. Until now little is known about the major protein forming these structured fibrous cell surface appendages, the genes involved or membrane anchoring of these filaments. These aspects were analyzed in depth in this study using environmental transcriptomics combined with imaging methods. Since a laboratory culture of this archaeon is not yet available, natural biofilm samples with high Ca. A. hamiconexum abundance were used for the entire analyses. The filamentous surface appendages spanned both membranes of the cell, which are composed of glycosyl-archaeol. The hami consisted of multiple copies of the same protein, the corresponding gene of which was identified via metagenome-mapped transcriptome analysis. The hamus subunit proteins, which are likely to self-assemble due to their predicted beta sheet topology, revealed no similiarity to known microbial flagella-, archaella-, fimbriae- or pili-proteins, but a high similarity to known S-layer proteins of the archaeal phylum at their N-terminal region (47-44% identity. Our results provide new insights into the structure of the unique hami and their major protein and indicate their divergent evolution with S-layer proteins.

    Hooking up (sex outside committed, romantic relationships) is feared to result from or lead to compromised psychological well-being among undergraduates, yet longitudinal evidence is scarce and inconclusive, and different hookup definitions complicate cross-study comparisons. This study examined short-term longitudinal associations with four well-being indicators (depression, anxiety, life satisfaction, and self-esteem) across several definitions of hookups based on relationship length (one time, longer casual, and any) and physical intimacy level (kissing, genital touching, oral sex, and intercourse). A university-wide sample of 666 Northeastern U.S. freshmen and juniors (63% female, 68% White) completed online surveys at the beginning and end of one academic semester. Linear and logistic regressions explored whether hookups over the semester were linked to later well-being, and whether initial well-being was linked to later hookups. Across all 96 regressions, statistically significant associations between well-being and hookups were infrequent (23%), predominantly confined to anxiety and life satisfaction, equally likely in the direction of higher (13%) as lower (10%) well-being, and affected by both casual relationship length and intimacy level. When gender differences emerged (11%), hookups were associated with higher well-being for women and lower well-being for men. This complex set of results points to the importance of researchers' choices in hookup definitions. PMID:25073476

    Full Text Available The aim of the present work is to characterize the vegetal raw material of the Calycophyllum spruceanum (Benth. Hook. f. ex K. Schum., Rubiaceae, known as "mulateiro", and to evaluate the influence of extractive parameters for attainment of standardized aqueous extractive solutions. The physical-chemical characterization of the samples was performed using pharmacopoeic and not pharmacopoeic methodologies. A 2³ factorial design was used to evaluate the influence of extraction techniques (infusion/decoction, drug: solvent ratio (2.5 and 7.5%, and extraction time (5 and 15 min on the total tannin content of aqueous extractive solutions from C. spruceanum. The extractive solution that showed higher total tannin and dry residue content had their physical-chemical characteristics determined. The results suggest that an aqueous extractive solution from rinds of C. spruceanum barks with higher tanning yield (9.9 g%, must be standardized using decoction as extraction methodology, with 2.5% of vegetal drug for an extraction time of 15 min. The results of the physical-chemical characterization suggest that environmental factors modify the properties of this species and, therefore, they can influence the quality and security of a product derived from this medicinal plant.

    Though the preferred welding process to weld aluminium alloy is frequently constant current gas tungsten arc welding (CCGTAW), it resulted in grain coarsening at the fusion zone and heat affected zone(HAZ). Hence, pulsed current gas tungsten arc welding(PCGTAW) was performed, to yield finer fusion zone grains, which leads to higher strength of AA6061 (Al-Mg-Si) aluminium alloy joints. In order to determine the most influential control factors which will yield minimum fusion zone grain size and maximum tensile strength of the joints, the traditional Hooke and Jeeves pattern search method was used. The experiments were carried out based on central composite design with 31 runs and an algorithm was developed to optimize the fusion zone grain size and the tensile strength of pulsed current gas tungsten arc welded AA6061 aluminium aUoy joints. The results indicate that the peak current (Ip) and base current (IB) are the most significant parameters, to decide the fusion zone grain size and the tensile strength of the AA6061 aluminum alloy joints.

    The linkage between herbal medicines and the sustainability of medical plants from which they are manufactured is increasingly being understood and receiving attention through international accords and trade labeling systems. However, little attention is paid to the fair trade aspects of this sector, including the issue of benefit-sharing agreements with traditional societies whose knowledge and resources are being exploited for commercial herbal medicine development and production. This article examines the case of Prunus africana (Hook.f.) Kalkman, from equatorial Africa. While the conservation and cultivation dimension of the trade in P. africana has been much discussed in literature, no research appears to have focused on the traditional resource rights and related ethical dimensions of this trade in traditional medicine of Africa. Serving as a cautionary tale for the unbridled exploitation of medicinal plants, the history of P. africana extraction is considered here in the context of relevant treaties and agreements existing today. These include the Nagoya Protocol, a supplementary agreement to the Convention on Biological Diversity, the Trade-Related Aspects of Intellectual Property Rights agreement from the World Trade Organization, and two African regional frameworks: the Swakopmund Protocol and the Organisation Africaine de la Propriété Intellectuelle Initiative. In the context of strengthening medicinal plant research in Africa, a novel international capacity-building project on traditional medicines for better public health in Africa will be discussed, illustrating how access and benefit sharing principles might be incorporated in future projects on traditional medicines.

    The hook method is used to measure the absolute gf values of the following lines: the first 13 members of the principal series, the ground-level transition at 2275.46 A, and the intercombination line at 6572.78 A in Ca I; the first 22 members of the principal series, the ground-level transitions at 2428.1 and 2680.08 A, and the intercombination line at 6892.6 A in Sr I; and the members from principal quantum numbers 12 to 21, inclusive, as well as the ground-level transitions at 2432.5, 2444.6, and 2454.06 A in Ba I. The results are compared with those of previous measurements, and the quantum-defect method is applied to plot the oscillator strengths of the discrete transitions in the principal series of Mg I, Ca I, and Sr I in order to obtain estimates of the photoionization cross sections at the first ionization limit. The resulting cross sections are found to be about twice as large as previous values based on vapor-pressure data.

    The prevalence of myopia in Chinese children has been rising each year. Research has shown that orthokeratology is a good method for controlling the progression of myopia. In this article, we review the current prevalence of myopia, the development and management of orthokeratology, and the myopia control methods used in China. A physical and health survey release indicated that the ratio of poor vision in every range of ages is still high in China. During the past 17 years, Chinese doctors have developed a standard fitting procedure and medical management of orthokeratology patients. This article also reviews the clinical studies in China for Ortho-K lenses, such as myopia control, effects and safety, corneal change, and lens design and fitting. Finally, we review the development of the International Academy of Orthokeratology Asia in China. PMID:26704137

  3. Photovoltaic for the Chinese

    International Nuclear Information System (INIS)

    China produces and exports about half of the photovoltaic cells made in the world. About 1000 Chinese enterprises work in the photovoltaic sector and the offer grows too fast to allow some enterprises to cope with lower and lower production costs. Research activities are a key element for the reduction of production costs but small companies can not usually sustain sufficient research. Economists foresee a strong reorganization of the sector: some enterprises will cease their photovoltaic activities, others will face financial difficulties, others will merge to make bigger companies. To make the demand bigger Chinese authorities are taking steps to develop the photovoltaic home market. The installed capacity of photovoltaic plants in China is expected to be somewhere between 11 GWc and 18 GWc in 2015, figures to be compared with only 0.9 GWc in 2010. (A.C.)

    We use daily survey data on Chinese institutional investors’ forecasts to measure investors' sentiment. Our empirical model uncovers that share prices and investor sentiment do not have a long-run relation; however, in the short-run, the mood of investors follows a positive feedback process. Hence, institutional investors are optimistic when previous market returns were positive. Contrarily, negative returns trigger a decline in sentiment, which reacts more sensitively to negative than positi...

    Full Text Available The history of modern Chinese Buddhism has begun to attract attention in recent years. Some scholars have done inspiring research as they unravel the integration of Buddhism into the highly secularized process of Chinese modernity by drawing on the repository of knowledge on modern China. While this special issue joins this exciting endeavor, it also uses Buddhism as a window to reflect on scholarship on Chinese modernity. Conceptually, this special issue presses scholars in the field of modern China to rethink the place of tradition in the course of modernity. Thematically we show the expansionist impulse of Chinese Buddhism: In addition to envisioning the geographical expansion of their religion, Chinese Buddhists have endeavored to enhance the significance of Buddhism in various dimensions of Chinese society in particular and human life in general.

    Full Text Available Identification of genes controlling shoot branching is crucial for improving plant architecture and increasing crop yield or biomass. A branching mutant of Chinese fir named “Dugansha” (Cunninghamia lanceolata var. dugan. has been isolated in our laboratory. We chose the cDNA-AFLP technique and an effective strategy to screen genes that potentially regulate shoot branching in Chinese fir using this mutant. An RNase III-like1 cDNA fragment named ClRTL1 was identified as a potential positive regulator. To investigate the function of ClRTL1 in regulating shoot branching, we cloned the full-length cDNA sequence from C. lanceolata (Lamb. Hook, deduced its secondary structure and function, and overexpressed the coding sequence in Arabidopsis. The ClRTL1 cDNA is 1045 bp and comprises an open reading frame of 705 bp. It encodes a protein of 235 amino acids. The deduced secondary structure of the ClRTL1 indicates that it is a mini-RNase III-like protein. The expression analysis and phenotypes of 35S: ClRTL1 in A. thaliana implies that ClRTL1 plays a role in promoting shoot branching in Chinese fir.

  13. Transmitting Chinese Medicine

    2015-01-01

    Historians of Chinese medicine acknowledge the plurality of Chinese medicine along both synchronic and diachronic dimensions. Yet, there remains a tendency to think of tradition as being defined by some unchanging features. The Chinese medical body is a case in point. This is assumed to have been formalised by the late Han dynasty around a system of internal organs, conduits, collaterals, and associated body structures. Although criticism was voiced from time to time, this body and the micro/macrocosmic cosmological resonances that underpin it are seen to persist until the present day. I challenge this view by attending to attempts by physicians in China and Japan in the period from the mid 16th to the late 18th century to reimagine this body. Working within the domain of cold damage therapeutics and combining philological scholarship, empirical observations, and new hermeneutic strategies these physicians worked their way towards a new territorial understanding of the body and of medicine as warfare that required an intimate familiarity with the body’s topography. In late imperial China this new view of the body and medicine was gradually re-absorbed into the mainstream. In Japan, however, it led to a break with this orthodoxy that in the Republican era became influential in China once more. I argue that attending further to the innovations of this period from a transnational perspective - commonly portrayed as one of decline - may help to go beyond the modern insistence to frame East Asian medicines as traditional.

    In recent years, uses of environment friendly and biodegradable natural insecticides of plant origin have received renewed attention as agents for vector control. The present study was undertaken to investigate the effect of aril and kernel extracts of Knema attenuata (Hook. f. & Thomson) Warb. (Myristicaceae) on larvae of Aedes albopictus Skuse and Anopheles stephensi Liston under laboratory conditions. The aril was extracted with chloroform and ethanol; the kernel was extracted with ethanol and hexane. The extracts were tested against the 3rd-4th instar larvae collected from Bunder area, Mangalore, India, which is a well-known fishing harbour, where several mosquito-borne diseases were reported. All the graded concentrations (100, 200, 300, 400 and 500 ppm) showed significant larval mortality after 24 h of observation. Chloroform extracts of aril showed 100% mortality against both larval forms of A. albopictus and A. stephensi at the concentration of 500 ppm. Among the extracts tested, chloroform extracts of aril and ethanol extracts of kernel exhibited higher toxicity against both A. albopictus (LC(50), 141 ppm and 159 ppm; LC(90), 290 ppm and 342 ppm) and A. stephensi (LC(50), 160 ppm and 162 ppm; LC90, 445 ppm and 458 ppm). Hexane extracts of kernel exhibited least toxicity against A. albopictus (LC50, 239 ppm; LC(90), 484 ppm), whereas ethanol extracts of aril showed the least toxicity against A. stephensi (LC(50), 290; LC(90), 498). A preliminary phytochemical assay revealed the presence of phenolics, tannins, steroids, terpenes, resins, and glycolipids in all the extracts. Alkaloids, flavonoids and saponins were absent. The lower LC(50) value of the chloroform extracts of K. attenuata aril indicates its potentiality as a larvicide against A. albopictus and A. stephensi mosquito larvae. PMID:21559763

    Full Text Available An experiment to ascertain the influence of fruit size on the yield of fluted pumpkin (Telfairia occidentalis Hook F. was conducted in 2011 and 2012 at Nsukka. The mature fruits of T. occidentalis were graded into three length groups: large (more than 50 cm, medium (34-50 cm and small (less than 34 cm. The experiment was laid out in randomized complete block design with six replications. The following data were collected: length of the longest vine, number of leaves/plant, vine diameter, marketable leaf and fruit yield. Data collected were subjected to analysis of variance while Genotype by Genotype x Environment interaction biplot was used to show which-won-where among the groups. Significant means were separated using Fisher’s least significant differences. Medium sized fruits gave the highest marketable leaf yield that was significantly higher than the small sized fruits in both years. Small sized fruits were significantly (p<0.05 lower in total leaf yield, fruit weight/hectare, fruit circumference (33.9 cm and length (22 cm. The biplot explained 100% of the variation in the fruit sizes. Large sized fruits were the best performer in fruit length, while medium sized fruits performed better in total marketable leaf yield, average fruit weight, number of fruits/hectare and total fruit weight/hectare. The highest Benefit Cost Ratio of 1.2 and 2.6 in 2011 and 2012, respectively were obtained from medium sized fruits Medium sized fruit are recommended in favour of small sized fruit for leaf and fruit production, having higher economic returns.

  20. Measurement of the densities of Cu and Ag vapours in a low-voltage switch using the hook method

    International Nuclear Information System (INIS)

    In a research model of a low-voltage circuit breaker with fixed contacts and windows for optical access, arcs powered by either a high-current transformer or a capacitor bank were initiated by the explosion of tungsten wires. Air at atmospheric pressure was the switching medium. The number densities of neutral silver and copper vapours from contacts and arc runners were measured simultaneously by the hook method using a Mach-Zehnder interferometer combined with a 1 m spectrograph and a gated intensified CCD camera. When an arc current was flowing, a substantial fraction of the metal vapour was ionized, and thus not amenable to a density measurement with the technique chosen. To nevertheless obtain approximate density values, the arc current was forced to zero within 8 to 10 µs at a preset time and measurements were carried out 100 µs after extinction of the arc. At that time the metal vapour was expected to have recombined to a large extent but not yet diffused to the walls in significant amounts. Depending on the current amplitude reached within the arc duration the arc remained anchored to the silver contacts or commutated to the copper arc runners. At a maximum current amplitude of 650 A Ag vapour densities of the order of 1022 m-3 were observed near the anode outweighing the Cu vapour density by a factor of 20. When at 1600 A the arc commutated to the arc runners a Cu vapour density of 8 × 1021 m-3 was reached while the Ag density remained limited to 2 × 1021 m-3. (paper)

The Paraná State laws prohibit its extraction; however, there is no research to support future management plans. This work characterized the natural occurrence of D. Sellowiana in an Araucaria angustifolia stand in the municipality of Rio Negro, Paraná State, using dendrometric variables after silvicultural intervention (clipping. D. sellowiana individuals (714 taller than the commercial height of 0.50 m were randomly sampled and assigned to the following treatments: plots with unclipped plants (T0, plots with plants clipped in the measurement (T1, and plots with plants clipped two years before in the measurement (T2. The variables analyzed were: density of the individuals/ha and plots, total and commercial caudex height (m, crown height (m, base diameter, crown (cm and frond (m, diameters, individual and total commercial volume. It was found significant difference between T1 and T2 for total height; between T2 and T0 and between T2 of T1 for crown and from diameters, individual commercial volume; between T0 and T1 and between TO and T2 for total commercial volume. The variables that characterized better the silvicultural interventions were the density of individuals and the total height. The occurred interventions revealed its importance for the management of the D. sellowiana because it favors the regeneration of the young plants for the conservation of the species, and benefits the development of the adult plants for its commercial exploitation.

The fractions were evaluated for phytochemical composition, lethality against brine shrimp larvae and in vitro antiplasmodial activity against Plasmodium falciparum strain. The obtained results revealed that the roots and leaf extracts of A. barteri exhibited broad spectrum of antiplasmodial activity (IC50 1.5 ± 0.7–6.2 ± 0.80 μg/mL. The aqueous leaf fractions displayed the most potent antiplasmodial activity with an IC50 value of 1.5 ± 0.7 μg/mL, which is comparable to reference antimalarial drug (IC50 value of 1.3 ± 0.2 μg/mL. The leaf fractions displayed higher activity than the root extracts. The highest minimum lethal concentration (105.2 ± 0.8 ppm was exhibited by the aqueous leaf extract followed closely by the root extract (120.2 ± 1.1 ppm. The leaf extracts contained higher polyphenols (45.3 ± 0.85 mgGAE/g and flavonoids (18.10 ± 0.2 mgCTE/g than the root extracts.

  3. Stuck in the tar sands : how the federal government's proposed climate change strategy lets oil companies off the hook

    International Nuclear Information System (INIS)

    The credibility of any federal climate change strategy must be measured against its ability to reduce emissions from the tar sands. However, the federal government has proposed a climate change strategy that would allow tar sands producers to double their total emissions over the next decade. This report discussed how the federal government's proposed climate change strategy lets oil companies off the hook. The report discussed the problems and harmful effects associated with tar sands development, including greenhouse gas emissions; water depletion and pollution; toxic air emissions; destruction of the boreal forest; violation of native rights; threat to energy security; and negative socio-economic spin-off from an overheated economy. The federal government's proposed strategy was also assessed in terms of its weak greenhouse gas targets; ignoring the recent growth in tar sands emissions; adopting intensity-based targets instead of hard caps on greenhouse gas pollution, allowing total emissions from the tar sands to keep climbing; putting off critical measures until 2018; awarding oil companies hundreds of millions of dollars in credits for meeting targets they have already adopted voluntarily; lowballing the price of oil and downplaying future growth in tar sands emissions; ignoring huge portions of the oil industry's greenhouse gas pollution; letting oil companies buy their way out at rockbottom prices instead of forcing them to reduce their own emissions; and subsidizing increased tar sands production. It was concluded that the federal government's proposed plan to reduce greenhouse gas emissions was inadequate, because it failed to crack down on rising greenhouse gas emissions from the tar sands, one of Canada's most carbon intensive and fastest growing industries. 29 refs., 1 appendix

    High-mobility group AT-hook protein 2 (HMGA 2) is a transcription factor associated with malignancy and poor prognosis in a variety of human cancers. We correlated HMGA 2 expression with clinical parameters, survival, and O-6-methylguanine-DNA methyltransferase methylation status (MGMT) in glioblastoma patients. HMGA 2 expression was determined by performing quantitative real-time polymerase chain reaction (qPCR) and immunohistochemistry (IHC) in 44 glioblastoma patients and 5 non-tumorous brain specimens as controls. Gene expression levels of MGMT methylated vs. unmethylated patients, and gene expression levels between patient groups, both for qPCR and IHC data were compared using the Mann-Whitney U test. The relationship between HMGA 2 expression, progression-free survival and overall survival was analyzed using the Kaplan-Meier method and the log-rank test. P-values of <0.05 were considered statistically significant throughout the analyses. The mean age of patients at diagnosis was 57.4±15.7 years, and the median survival was 16 months (SE 2.8; 95% CI, 10.6-21.4). HMGA 2 gene expression was significantly higher in glioblastoma compared to normal brain tissue on qPCR (mean, 0.35; SD, 0.27 vs. 0.03, SD, 0.05) and IHC levels (IRS mean, 17.21; SD, 7.43 vs. 3.20; SD, 1.68) (p=0.001). Survival analysis revealed that HMGA 2 overexpression was associated with a shorter progression-free and overall survival time in patients with methylation (n=24). The present study shows a tendency that HMGA 2 overexpression correlates with a poor prognosis of glioblastoma patients independent of MGMT methylation status. The results suggest that HMGA 2 could play an important role in the treatment of glioblastoma and could have a function in prognosis of this type of cancer. PMID:26892260

    The aim of this study was to identify regional structural differences in the brains of native speakers of a tonal language (Chinese) compared to nontonal (European) language speakers. Our expectation was that there would be differences in regions implicated in pitch perception and production. We therefore compared structural brain images in three groups of participants: 31 who were native Chinese speakers; 7 who were native English speakers who had learnt Chinese in adulthood; and 21 European multilinguals who did not speak Chinese. The results identified two brain regions in the vicinity of the right anterior temporal lobe and the left insula where speakers of Chinese had significantly greater gray and white matter density compared with those who did not speak Chinese. Importantly, the effects were found in both native Chinese speakers and European subjects who learnt Chinese as a non-native language, illustrating that they were language related and not ethnicity effects. On the basis of prior studies, we suggest that the locations of these gray and white matter changes in speakers of a tonal language are consistent with a role in linking the pitch of words to their meaning.

  18. Effect of compression on hydroscopicity of extracted Chinese fir heartwood

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    In order to clarify the effects of extraction and compression on the hydroscopicity of wood, Chinese fir (Cunninghamia laneeolata Hook.) heartwood samples with or without extraction were radially or tangentially compressed under water-saturated condition at room temperature. Warm water and 1% sodium hydroxide were used as different solutions for extraction. Water absorp-tion capacity and moisture adsorption isotherms of the eornpressed samples were then tested. The fractai dimension of internal wood surfaces (Dfs) was calculated based on adsorption isotherms by FHH equation. Results showed that in both compressed groups, the hydroseopieity of samples extracted by sodium hydroxide solution improved greatly, while that of samples extracted by warm water changed little, compared with that of water-saturated samples. Recovery of set and the change of hydroscopic environment inside wood were main reasons for the difference of water absorption among water-saturated samples and samples extracted with warm water and sodium hydroxide solution. The swelling rate of samples extracted by sodium hydroxide solution significantly increased.Moreover, the swelling rate in the tangential direction of tangentially compressed samples was obviously higher than that in radial direction of radially compressed ones, Des values of woods extracted by warm water and sodium hydroxide solution decreased by 0.002 and 0.007 in a radially compressed group and by 0.013 and 0.013 in a tangentially compressed group, compared to those of water-saturated one. Therefore, the conclusion can be made that the extraction and compression treatments used in this study have no obvious effects on internal wood surface.

    Fractures of the hook of the hamate are a rare event. The fracture cannot always be detected clinically and standard radiographs do not always provide an overlap-free image of the hook of the hamate, so that fractures can easily be overlooked. The objective of the present study was to examine if the sensitivity of detecting hamulus ossis hamati fractures can further be improved by a modified conventional radiographic projection. After dissection of the hook of the hamate on 10 cadaver hands, a fracture was produced close to the base using a surgical chisel. Conventional radiographs were then performed in four different projections (dorso-palmar, lateral, carpal-tunnel and oblique view). The oblique view was obtained in a 45 supination position, slight extension and radial duction, with the tube tilted from distal to proximal by 30 . An axial spiral CT was used as a reference for detection of the fracture. The highest sensitivity of the conventional radiographs, with 8/10 identified fractures (80%), was achieved by the oblique view. The carpal-tunnel view with 4/10 (40%) and the dorso-palmar projection with 3/10 (30%) were much lower. All fractures were missed in the lateral projection. If all of the conventional radiographic projections are taken into account, the sensitivity is increased to 90%. All of the fractures were reliably detected in the axial CT-image. If a hamulus ossis hamati fracture is suspected clinically, in addition to the dorso-palmar and carpal-tunnel view, the special oblique view described here should be performed as a third projection plane, while the lateral view can be dispensed with. However, even if all projections are taken into account, a negative finding in the conventional radiographic imaging does not exclude a fracture with absolute certainty. In such cases, a CT or MRI should be performed to exclude a fracture. (orig.)

  20. XBAT35, a Novel Arabidopsis RING E3 Ligase Exhibiting Dual Targeting of Its Splice Isoforms,Is Involved in Ethylene-Mediated Regulation of Apical Hook Curvature

    2012-01-01

    The Arabidopsis XBAT35 is one of five structurally related ankyrin repeat-containing Really interesting New Gene (RING) E3 ligases involved in ubiquitin-mediated protein degradation,which plays key roles in a wide range of cellular processes.Here,we show that the XBAT35 gene undergoes alternative splicing,generating two transcripts that are constitutively expressed in all plant tissues.The two splice variants derive from an exon skipping event that excludes an in-frame segment from the XBAT35 precursor mRNA,giving rise to two protein isoforms that differ solely in the presence of a nuclear localization signal (NLS).Transient expression assays indicate that the isoform lacking the NLS localizes in the cytoplasm of plant cells,whereas the other is targeted to the nucleus,accumulating in nuclear speckles.Both isoforms are functional E3 ligases,as assessed by in vitro ubiquitination assays.Two insertion mutant alleles and RNA-interference (RNAi) silencing lines for XBAT35 display no evident phenotypes under normal growth conditions,but exhibit hypersensitivity to the ethylene precursor 1-aminocyclopropane-1-carboxylate (ACC) during apical hook exaggeration in the dark,which is rescued by an inhibitor of ethylene perception.Independent expression of each XBAT35 splice variant in the mutant background indicates that the two isoforms may differentially contribute to apical hook formation but are both functional in this ethylene-mediated response.Thus,XBAT35 defines a novel player in ethylene signaling involved in negatively regulating apical hook curvature,with alternative splicing controlling dual targeting of this E3 ubiquitin ligase to the nuclear and cytoplasmic compartments.

    Full Text Available The experience of social anxiety has largely been investigated among Western populations; much less is known about social anxiety in other cultures. Unlike the Western culture, the Chinese emphasize interdependence and harmony with social others. In addition, it is unclear if Western constructed instruments adequately capture culturally conditioned conceptualizations and manifestations of social anxiety that might be specific to the Chinese. The present study employed a sequence of qualitative and quantitative approaches to examine the assessment of social anxiety among the Chinese people. Interviews and focus group discussions with Chinese participants revealed that some items containing the experience of social anxiety among the Chinese are not present in existing Western measures. Factor analysis was employed to examine the factor structure of the more comprehensive scale. This approach revealed an “other concerned anxiety” factor that appears to be specific to the Chinese. Subsequent analysis found that the new factor—other concerned anxiety—functioned the same as other social anxiety factors in their association with risk factors of social anxiety, such as attachment, parenting, behavioral inhibition/activation, and attitude toward group. The implications of these findings for a more culturally sensitive assessment tool of social anxiety among the Chinese were discussed.

This project provides highly detailed and accurate datasets of a portion of the Sandy Hook Unit of Gateway National Recreation Area in New Jersey, acquired post-Nor'Ida (November 2009 nor'easter) on December 4, 2009. The datasets are made available for use as a management tool to research scientists and natural-resource managers. An innovative airborne lidar instrument originally developed at the NASA Wallops Flight Facility, and known as the Experimental Advanced Airborne Research Lidar (EAARL), was used during data acquisition. The EAARL system is a raster-scanning, waveform-resolving, green-wavelength (532-nanometer) lidar designed to map near-shore bathymetry, topography, and vegetation structure simultaneously. The EAARL sensor suite includes the raster-scanning, water-penetrating full-waveform adaptive lidar, a down-looking red-green-blue (RGB) digital camera, a high-resolution multispectral color infrared (CIR) camera, two precision dual-frequency kinematic carrier-phase GPS receivers, and an integrated miniature digital inertial measurement unit, which provide for sub-meter georeferencing of each laser sample. The nominal EAARL platform is a twin-engine aircraft, but the instrument was deployed on a Pilatus PC-6. A single pilot, a lidar operator, and a data analyst constitute the crew for most survey operations. This sensor has the potential to make significant contributions in measuring sub-aerial and submarine coastal topography within cross-environmental surveys. Elevation measurements were collected over the survey area using the EAARL system, and the resulting data were then

    Chinese fir (Cunninghamia lanceolata [Lamb.] Hook) is one of the most important plantation tree species in China with good timber quality and fast growth. It covers an area of 8.54 million hectare, which corresponds to 21% of the total plantation area and 32% of total plantation volume in China. With the increasing market demand, an accurate estimation and prediction of merchantable volume at tree- and stand-level is becoming important for plantation owners. Although there are many studies on the total tree volume estimation from allometric models, these allometric models cannot predict tree- and stand-level merchantable volume at any merchantable height, and the stand-level merchantable volume model was not seen yet in Chinese fir plantations. This study aimed to develop (1) a compatible taper function for tree-level merchantable volume estimation, and (2) a stand-level merchantable volume model for Chinese fir plantations. This “taper function system” consisted in a taper function, a merchantable volume equation and a total tree volume equation. 46 Chinese fir trees were felled to develop the taper function in Shitai County, Anhui province, China. A second-order continuous autoregressive error structure corrected the inherent serial autocorrelation of different observations in one tree. The taper function and volume equations were fitted simultaneously after autocorrelation correction. The compatible taper function fitted well to our data and had very good performances in diameter and total tree volume prediction. The stand-level merchantable volume equation based on the ratio approach was developed using basal area, dominant height, quadratic mean diameter and top diameter (ranging from 0 to 30 cm) as independent variables. At last, a total stand-level volume table using stand basal area and dominant height as variables was proposed for local forest managers to simplify the stand volume estimation. PMID:26799399

    We developed a contactless interface that exploits hand gestures to effectively control medical images in the operating room. We developed an in-house program called GestureHook that exploits message hooking techniques to convert gestures into specific functions. For quantitative evaluation of this program, we used gestures to control images of a dynamic biliary CT study and compared the results with those of a mouse (8.54 ± 1.77 s to 5.29 ± 1.00 s; p gestures and the success rates of tasks based on clinical scenarios. For clinical applications, this program was set up in the operating room to browse images for plastic surgery. A surgeon browsed images from three different programs: CT images from a PACS program, volume-rendered images from a 3D PACS program, and surgical planning photographs from a basic image viewing program. All programs could be seamlessly controlled by gestures and motions. This approach can control all operating room programs without source code modification and provide surgeons with a new way to safely browse through images and easily switch applications during surgical procedures.

    Full Text Available Geissoschizine methyl ether (GM is an indole alkaloid found in Uncaria hook, which is a galenical constituent of yokukansan, a traditional Japanese medicine. GM has been identified as the active component responsible for anti-aggressive effects. In this study, the metabolic profiling of GM in rat and human liver microsomes was investigated. Thirteen metabolites of GM were elucidated and identified using a high-performance liquid chromatography with tandem mass spectrometry method, and their molecular structures were proposed on the basis of the characteristics of their precursor ions, product ions, and chromatographic retention times. There were no differences in the metabolites between the rat and human liver microsomes. Among the 13 identified metabolites, there were two demethylation metabolites, one dehydrogenation metabolite, three methylation metabolites, three oxidation metabolites, two water-adduct metabolites, one di-demethylation metabolite, and one water-adduct metabolite followed by oxidation. The metabolic pathways of GM were proposed on the basis of this study. This study will be helpful in understanding the metabolic routes of GM and related Uncaria hook alkaloids, and provide useful information on the pharmacokinetics and pharmacodynamics. This is the first report that describes the separation and identification of GM metabolites in rat and human liver microsomes.

    Geissoschizine methyl ether (GM) is an indole alkaloid found in Uncaria hook, which is a galenical constituent of yokukansan, a traditional Japanese medicine. GM has been identified as the active component responsible for anti-aggressive effects. In this study, the metabolic profiling of GM in rat and human liver microsomes was investigated. Thirteen metabolites of GM were elucidated and identified using a high-performance liquid chromatography with tandem mass spectrometry method, and their molecular structures were proposed on the basis of the characteristics of their precursor ions, product ions, and chromatographic retention times. There were no differences in the metabolites between the rat and human liver microsomes. Among the 13 identified metabolites, there were two demethylation metabolites, one dehydrogenation metabolite, three methylation metabolites, three oxidation metabolites, two water-adduct metabolites, one di-demethylation metabolite, and one water-adduct metabolite followed by oxidation. The metabolic pathways of GM were proposed on the basis of this study. This study will be helpful in understanding the metabolic routes of GM and related Uncaria hook alkaloids, and provide useful information on the pharmacokinetics and pharmacodynamics. This is the first report that describes the separation and identification of GM metabolites in rat and human liver microsomes. PMID:25633336

    This study has identified the active cerebral areas of normal Chinese that are associated with Chinese semantic processing using functional brain imaging. According to the traditional cognitive theory, semantic processing is not particularly associated with or affected by input modality. The functional brain imaging experiments were conducted to identify the common active areas of two modalities when subjects perform Chinese semantic tasks through reading and listening respectively. The result has shown that the common active areas include left inferior frontal gyrus (BA 44/45), left posterior inferior temporal gyrus (BA37); the joint area of inferior parietal lobules (BA40) and superior temporal gyrus, the ventral occipital areas and cerebella of both hemispheres. It gives important clue to further discerning the roles of different cerebral areas in Chinese semantic processing.

Somalia has been embroiled in armed conflicts between feuding warlords since 1991, without a central government that can put the country under effective control. In an interview with Beijing Review reporter Yan Wei, Somalia’s Ambassador to China Mohammed Awil called on the international community to help his war-torn country fight piracy, stop illegal fishing and waste dumping in Somali waters and achieve peace and reconciliation. The ambassador also gave positive evaluation to China’s naval presence on Somali waters. Excerpts of the interview follow

  11. Chinese culture and fertility decline.

    1992-01-01

    Coale has suggested that cultural factors exert a significant influence on fertility reduction; countries in the "Chinese cultural circle" would be the first to show fertility decline. In China, the view was that traditional Chinese culture contributed to increased population. This paper examines the nature of the relationship between Chinese culture and fertility. Attention was directed to a comparison of fertility rates of developing countries with strong Chinese cultural influence and of fertility within different regions of China. Discussion was followed by an explanation of the theoretical impact of Chinese culture on fertility and direct and indirect beliefs and practices that might either enhance or hinder fertility decline. Emigration to neighboring countries occurred after the Qing dynasty. Fertility after the 1950s declined markedly in Japan, Singapore, Hong Kong, South Korea, Taiwan, and mainland China: all countries within the Chinese cultural circle. Other countries within the Chinese circle which have higher fertility, yet lower fertility than other non-Chinese cultural countries, are Malaysia, Thailand, and Indonesia. Within China, regions with similar fertility patterns are identified as coastal regions, central plains, and mountainous and plateau regions. The Han ethnic group has lower fertility than that of ethnic minorities; regions with large Han populations have lower fertility. Overseas Chinese in East Asian countries also tend to have lower fertility than their host populations. Chinese culture consisted of the assimilation of other cultures over 5000 years. Fertility decline was dependent on the population's desire to limit reproduction, favorable social mechanisms, and availability of contraception: all factors related to economic development. Chinese culture affects fertility reduction by affecting reproductive views and social mechanisms directly, and indirectly through economics. Confucianism emphasizes collectivism, self

  17. Chinese investments in the EU

    2010-12-01

    Full Text Available China’s investments in the European Union are much lower than what you may expect given the economic size of both entities. These relatively low investments in Europe are a combination of priority and obstacles. The priority for investments is clearly in Asia, Africa and Latin America. This regional pattern is heavily influenced by the need to solve the resource shortage in the medium and long term. The investments in Europe and the United States are mostly market seeking investments. Research specifically focused on Chinese M&A abroad comes to the same conclusion. The success rate of Chinese M&A abroad is much lower than what we see with respect to American or European investments abroad. In this paper, we examine why Chinese firms are facing more difficulties in the European Union than in other regions. The paper focuses on Chinese M&A as proxy for total foreign direct investments abroad. By looking at the factors that have been documented as influencing the level of M&A abroad, it becomes clear that Chinese firms in Europe are hindered by many factors. For example, the trade between China and the EU is relatively low, the institutional quality is lower compared to the United States, there is less experience with respect to Europe and relatively many deals relate to State Owned Enterprises (SOE which makes the deal sensitive. So it is logical that Chinese investments are not very high in Europe. However, the research makes clear that the obstacles for Chinese investments in Europe are disappearing step by step. In that sense, we expect a strong increase of Chinese investments in Europe in the future.

  2. A Hierarchical Bayesian Model to Predict Self-Thinning Line for Chinese Fir in Southern China.

    Directory of Open Access Journals (Sweden)

    Xiongqing Zhang

    Full Text Available Self-thinning is a dynamic equilibrium between forest growth and mortality at full site occupancy. Parameters of the self-thinning lines are often confounded by differences across various stand and site conditions. For overcoming the problem of hierarchical and repeated measures, we used hierarchical Bayesian method to estimate the self-thinning line. The results showed that the self-thinning line for Chinese fir (Cunninghamia lanceolata (Lamb.Hook. plantations was not sensitive to the initial planting density. The uncertainty of model predictions was mostly due to within-subject variability. The simulation precision of hierarchical Bayesian method was better than that of stochastic frontier function (SFF. Hierarchical Bayesian method provided a reasonable explanation of the impact of other variables (site quality, soil type, aspect, etc. on self-thinning line, which gave us the posterior distribution of parameters of self-thinning line. The research of self-thinning relationship could be benefit from the use of hierarchical Bayesian method.

    Aim: To develop classification criteria for Chinese pulse diagnosis and to objectify the ancient diagnostic technique. Methods: Chinese pulse curves are treated as wave signals. Multidimensional variable analysis is performed to provide the best curve fit between the recorded Chinese pulse waveforms and the collective Gamma density functions. Results: Chinese pulses can be recognized quantitatively by the newly-developed four classification indices, that is, the wave length, the relative phase difference, the rate parameter, and the peak ratio. The new quantitative classification not only reduces the dependency of pulse diagnosis on Chinese physician's experience, but also is able to interpret pathological wrist-pulse waveforms more precisely. Conclusions: Traditionally, Chinese physicians use fingertips to feel the wrist-pulses of patients in order to determine their health conditions. The qualitative theory of the Chinese pulse diagnosis is based on the experience of Chinese physicians for thousands of year...

The present study concentrated on the assessment of growth, wood property traits, and strobili number in a 12-year grafted clone test of 62 Chinese fir breeding parents, aiming to describe the variation and correlations between these traits and to identify parent clones with the highest potential for future breeding. The results indicate that all of the growth (height, diameter at breast height, stem volume, crown-width and wood property (wood basic density and hygroscopicity traits varied significantly (p < 0.01 among clones, with coefficients of variation ranging from 7.6% to 30.6%. Furthermore, these traits consistently had a moderate to high (0.39–0.87 repeatability estimate (broad-sense heritability. Remarkable clonal differences were also observed for the production of male and female strobili. Phenotypic correlations among growth traits were strong (p < 0.01 and positive. Significantly negative correlations (p < 0.01 or 0.05 were found between wood basic density and growth (except for height and hygroscopicity. The production of male and female strobili appeared to be significantly (p < 0.01 positively correlated with each other. A notable number of faster-growing parent clones were identified (n = 30; 11 of these had higher density wood with an average realized gain of 10.5% in diameter, and a 5.4% gain in wood basic density. When selection was made for growth and strobili, 10 faster-growing parent clones with medium to high production of female strobili were identified.
