    In this paper I propose a possible use of Roman Dodecahedra, which are bronze artifacts of gallo-roman origin dating from the 2nd or 3rd centuries AD, for playing a bowling game. The presence of holes and knobs can be quite important during collisions. Moreover, in several of these objects, the holes have different sizes providing a biased rigid body.

  8. The Tibetan Singing Bowl

    CERN Document Server

    Terwagne, Denis

    2010-01-01

    The Tibetan singing bowl is a type of standing bell. Originating from Himalayan fire cults as early as the 5th century BC, they have since been used in religious ceremonies, for shamanic journeying, exorcism, meditation and shakra adjustment. A singing bowl is played by striking or rubbing its rim with a wooden or leather-wrapped mallet. The sides and rim of the bowl then vibrate to produce a rich sound. When the bowl is filled with water, this excitation can cause crispation of the water surface that can be followed by more complicated surface wave patterns and ultimately the creation of droplets. We here demonstrate the means by which the Tibetan singing bowl can levitate droplets. This is a sample arXiv article illustrating the use of fluid dynamics videos.

    The biological activities of six symmetrically substituted 2-methoxy-benzyl polymethylene tetraamines (1-4) and diphenylethyl polymethylene tetraamines (5 and 6) as N-methyl-D-aspartate (NMDA) receptor channel blockers, were evaluated in vitro and in vivo. Although all compounds exhibited stronger channel block activities in comparison to memantine in Xenopus oocytes voltage clamped at -70 mV, only compound 2 (0.4 mg/kg intravenous injection) decreased the size of brain infarction in a photochemically induced thrombosis model mice at the same extent of memantine (10mg/kg intravenous injection). Other compounds (1, 3, 4, 5 and 6) did not decrease the size of brain infarction significantly due to the limited injection doses. The present study suggests that compound 2 could represent a valuable lead compound to design low toxicity polyamines for clinical use against stroke. PMID:23692871

    2011-01-01

    We present the results of an experimental investigation of the acoustics and fluid dynamics of Tibetan singing bowls. Their acoustic behavior is rationalized in terms of the related dynamics of standing bells and wine glasses. Striking or rubbing a fluid-filled bowl excites wall vibrations, and concomitant waves at the fluid surface. Acoustic excitation of the bowl's natural vibrational modes allows for a controlled study in which the evolution of the surface waves with increasing forcing amplitude is detailed. Particular attention is given to rationalizing the observed criteria for the onset of edge-induced Faraday waves and droplet generation via surface fracture. Our study indicates that drops may be levitated on the fluid surface, induced to bounce on or skip across the vibrating fluid surface.

    10 November 1972: CERN’s Bent Stumpe places an order for 12 bowling balls for a total cost of 95 US dollars. Although not evident at first sight, he is buying the heart of some of the first tracking devices to be used in the SPS control room. Today, Bent Stumpe’s device would be called a desktop mouse…   The first order for 4 bowling balls later changed to 12 balls. The bowling balls became the heart of Bent Stumpe's mouse. Almost 40 years ago, the web, Wikipedia and Google did not exist and it was much more difficult to know whether other people in other parts of the world or even in the same laboratory were facing the same problems or developing the same tools. At that time, Bent Stumpe was an electronics engineer, newly recruited to work on developments for the SPS Central Control room. One of the things his supervisor asked him to build as soon as possible was a device to control a pointer on a screen, also called a tracker ball. The heart of the device was the...

    Full Text Available Background: Ruthenium (Ru tetraamines are being increasingly used as nitric oxide (NO carriers. In this context, pharmacological studies have become highly relevant to better understand the mechanism of action involved. Objective: To evaluate the vascular response of the tetraamines trans-[RuII(NH34(Py(NO]3+, trans-[RuII(Cl(NO (cyclan](PF62, and trans-[RuII(NH34(4-acPy(NO]3+. Methods: Aortic rings were contracted with noradrenaline (10−6 M. After voltage stabilization, a single concentration (10−6 M of the compounds was added to the assay medium. The responses were recorded during 120 min. Vascular integrity was assessed functionally using acetylcholine at 10−6 M and sodium nitroprusside at 10−6 M as well as by histological examination. Results: Histological analysis confirmed the presence or absence of endothelial cells in those tissues. All tetraamine complexes altered the contractile response induced by norepinephrine, resulting in increased tone followed by relaxation. In rings with endothelium, the inhibition of endothelial NO caused a reduction of the contractile effect caused by pyridine NO. No significant responses were observed in rings with endothelium after treatment with cyclan NO. In contrast, in rings without endothelium, the inhibition of guanylate cyclase significantly reduced the contractile response caused by the pyridine NO and cyclan NO complexes, and both complexes caused a relaxing effect. Conclusion: The results indicate that the vascular effect of the evaluated complexes involved a decrease in the vascular tone induced by norepinephrine (10−6 M at the end of the incubation period in aortic rings with and without endothelium, indicating the slow release of NO from these complexes and suggesting that the ligands promoted chemical stability to the molecule. Moreover, we demonstrated that the association of Ru with NO is more stable when the ligands pyridine and cyclan are used in the formulation of the compound.

    Battelle Pacific Northwest Laboratory has published two volumes on the economic evaluation of various proposed configurations and plant sizes for the four solar thermal technologies. These are the latest in a series of publications sponsored by the Department of Energy (DOE) on plant and operational costs and are more complete in that they include calculations of electrical output. These latest Battelle volumes use the 1976 solar data from Barstow, Calif., and by calculating or estimating the energy conversion efficiency of each element in the process from sun to electricity predict the output and cost of electricity from different plant sizes for each of the four technologies. In this paper a comparison is presented of the component efficiencies developed by Battelle and those of the solar bowl at Crosbyton, Tex.

    Carbon-13 nuclear magnetic resonance spectra of a series of trans-diacido(1,10-diamino-4,7-diazadecane)cobalt(III) complexes (trans-Co(3,2,3-tet)X/sub 2/, X = Br/sup -/, Cl/sup -/, N/sub 3//sup -/, NO/sub 2//sup -/, OAc) and trans-diacido(1,9-diamino-3,7-diazononane)cobalt(III) complexes (trans-Co(2,3,2-tet)X/sub 2/, X = Cl/sup -/, GlyH, /sup -/OAc, NH/sub 3/, NO/sub 2//sup -/) will be discussed. The /sup 13/C chemical shift is found to be linearly dependent on the ligand field strength (estimated from the electronic spectrum) of the axial ligands (X). The shielding of selected carbon atoms within the tetraamine ligand, which has been attributed to the central metal ion, increases with increasing axial ligand field strength.

    1983-10-01

    Carbon 13 NMR was found to be an extremely sensitive probe of the stereochemistry of this series of diamagnetic ''Werner'' complexes. Our interpretation is based upon two parameters, the donation of electron density to the metal and the steric perturbation required for coordination. The different symmetry of the complexes often permits determination of stereochemistry from the electronic spectrum. In addition, other methods including vibrational spectroscopy and proton NMR, have been used with some success to determine stereochemistry. These methods suffer, however, from a lack of sensitivity, especially in complexes with unsymmetrical ligands. In the course of continuing study of the stereochemistry of six coordinate transition metal complexes, we have investigated a large variety of cobalt(III) complexes with various tetraamine ligands.

    Tibetan bowls produce rich penetrating sounds, used in musical contexts and to induce a state of relaxation for meditation or therapy purposes. To understand the dynamics of these instruments under impact and rubbing excitation, we developed a simulation method based on the modal approach, following our previous papers on physical modeling of plucked/bowed strings and impacted/bowed bars. This technique is based on a compact representation of the system dynamics, in terms of the unconstrained bowl modes. Nonlinear contact/friction interaction forces, between the exciter (puja) and the bowl, are computed at each time step and projected on the bowl modal basis, followed by step integration of the modal equations. We explore the behavior of two different-sized bowls, for extensive ranges of excitation conditions (contact/friction parameters, normal force, and tangential puja velocity). Numerical results and experiments show that various self-excited motions may arise depending on the playing conditions and, mainly, on the contact/friction interaction parameters. Indeed, triggering of a given bowl modal frequency mainly depends on the puja material. Computed animations and experiments demonstrate that self-excited modes spin, following the puja motion. Accordingly, the sensed pressure field pulsates, with frequency controlled by the puja spinning velocity and the spatial pattern of the singing mode.

Data were accumulated at 5 min intervals to determine the gastric emptying time (GET). The results showed that the gastric emptying time was prolonged in 12 patients and decreased in 8. All 12 patients with prolonged emptying time were given 10 mg metoclopramide intravenously; 9 of these had a good response and 3 had no response. Although all patients had subjective symptoms of gastric dysfunction, the results indicate that about 60% had delayed and 40% had rapid gastric emptying. The findings of two extremes of gastric emptying time remain to be explained, however, this enables (Albibi and McCullum 1983) objective documentation of gastric emptying as this technique (American Psychiatric Association 1980) can separate those patients with rapid GET from those with prolonged GET, who might benefit from metoclopramide.

  5. Isoguanine octamer: From bowl to ball

    Gu, Jiande; Wang, Jing; Leszczynski, Jerzy

    2007-09-01

    Isoguanine (2-oxo-6-amino-guanine, isoG) can form the higher-order self-pairing ionophore structures by regulating the concentration of metal ions. The metal ion coordinated isoG-tetrads adopt bowl-like shape with the metal ion located at the bottom of the bowl. The present study of the formation of the H-bonded octamers ((isoG 4-M +) 2; M + = Na +, K +) illustrates that the bowl-shaped isoG 4-M + complexes are able to form the extraordinary ball-shaped octamers (isoG 4-M +) 2 H-bonded through the H(N6) and N7 sites. A moderate energy barrier predicted for the process of separating the ball-shaped octamer into two bowl-shaped tetrads and the unique structural features of the octamer suggests a possibility towards construction of the self-assembled isoG nanostructures.

    Stereoelectronic complementarity between the active site of an enzyme and the transition state of a reaction is one of the tenets of enzyme catalysis. This report illustrates the principles of enzyme catalysis (first proposed by Pauling and Jencks) through a well-defined model system that has been fully characterized crystallographically, computationally and kinetically. Catalysis of the bowl-to-bowl inversion processes that pertain to corannulene is achieved by combining ground-state destabilization and transition-state stabilization within the cavity of an extended tetracationic cyclophane. This synthetic receptor fulfils a role reminiscent of a catalytic antibody by stabilizing the planar transition state for the bowl-to-bowl inversion of (ethyl)corannulene (which accelerates this process by a factor of ten at room temperature) by an induced-fit mechanism first formulated by Koshland.

  9. Bowl inversion state controlled by intermolecular interactions

    International Nuclear Information System (INIS)

    Full text: Bowl-shaped pi-conjugated compounds are important not only as model compounds of fullerenes but also as possible hosts for different guest molecules. Recent studies regarding the storage of possible energy carriers such as hydrogen and methane in nano-structured carbon materials have further increased the interest in well defined model compounds that allow for a detailed investigation of host-guest interactions in order to optimize the storage capacity of technologically relevant carbon-based materials. Within this context we investigated the structural properties of monolayer films of sumanene (C21H12) deposited on Ag(111). Based on STM experiments we find that the fraction of molecules having a bowl-down adsorption geometry is coverage-dependent, indicating that the bowl-inversion state is determined by intermolecular interactions. The experimental findings are rationalized by density functional theory (DFT) calculations, which reveal a subtle interplay between molecule-substrate and molecule- molecule interactions that is responsible for the abrupt structural change involving inversion of a fraction of the molecules and reorientation of the molecules with respect to the surface normal.

Acoustic excitation of the bowl's natural vibrational modes allows for a controlled study in which the evolution of the surface waves with increasing forcing amplitude is detailed. Particular attention is given to rationalizing the observed criteria for the onset of edge-induced Faraday waves and droplet generation via surface fracture. Our study indicates that drops may be levitated on the fluid surface, induced to bounce on or skip across the vibrating fluid surface.

    2015-12-01

    The Dust Bowl refers to a disaster focused in the Southern Great Plains of North America during the 1930s, when the region experienced extreme wind erosion. Dry farming techniques increased soil erodibility. Drought reduced both soil cohesion, making it more erodible, and land cover, leaving the soil less protected from wind action. Low crop prices (driven by the Great Depression), extremely poor harvests (driven by drought), and lack of knowledge of regionally-appropriate tillage practices left farmers unable to implement erosion control on their land. The 1930s drought was severe, but neither unusual in the region nor extreme in length from a climatological perspective. Sea-surface temperature changes in the Atlantic and Pacific forced changes in the large-scale atmospheric circulation over North America. The result was persistent, intensifying drought within the Southern Great Plains for multiple years, causing a cascade of desiccation. Increased atmospheric dust and increased frequency of cyclones crossing the region may also have exacerbated Dust Bowl conditions. The Dust Bowl resulted from the simultaneous combination of drought and economic depression in a region where farmers had not yet learned effective land management techniques. Economic recovery, cessation of drought, and implementation of erosion control programs combined to end the Dust Bowl by the end of the 1930s. Many lessons were learned from the 1930s Dust Bowl regarding the physical and anthropogenic causes of dust storms and how to mitigate them. As a result, though dust storms continue on the Southern Great Plains, their severity is significantly reduced. Before our plow breaks open the soil at all, It's necessary to study the ways of the winds And the changing ways of the skies, and also to know… What crops will prosper there and what will not.

  19. Kiwifruit: taking its place in the global fruit bowl.

    Science.gov (United States)

    Ward, Carol; Courtney, David

    2013-01-01

    While the world total production of kiwifruit has increased by over 50% during the last decade, the kiwifruit remains a niche fruit, taking up an estimated 0.22% of the global fruit bowl, which is dominated by apples, oranges, and bananas. Even though kiwifruit's share of the global fruit bowl has remained largely unchanged over the past 15 years, the scope for growth in the category is significant, with the nutritional and production characteristics of kiwifruit being on the right side of key global consumer trends around health and sustainability. Taking advantage of these consumer trends is one of two key challenges for the global kiwifruit industry. The second challenge is to harness the diverse natural and cultivated range of kiwifruit varieties (colors, flavors, sizes, and shapes) to stimulate the interest of consumers and grow the share of kiwifruit in the fruit basket through selecting cultivars that can develop meaningful market segments and meet consumer demand.

    Full Text Available The excavation works being carried out since 1989 at Dorylaion (Eskişehir/Turkey results in many findings belonging to different civilizations spanning from the First Bronze age to Ottoman period. One of the important groups of these findings is the moldmade bowls, familiarly known as the Megarian bowls from the Hellenistic period (330-30 B.C.. In a frame of an archaeometry project work, these artifacts were characterized with different analytical techniques. Wavelength dispersive X-ray fluorescence (WDXRF and X-ray diffraction (XRD were used to study chemical and mineralogical composition of the bodies. Thermogravimetric-differential thermal analyses (TG-DTA were performed to make the estimation of firing temperature of the sherds. Scanning electron microscopy (SEM and energy dispersive X-ray spectrometry (EDX were performed for the microstructural and microchemical characterization of body and slip layers of the selected potsherds. Based on the analyses results, the bowls should have been prepared from carbonated and siliceous clays and fired at the temperatures from 600 to 1000 °C. They have also iron-rich slip layers with different colors indicating probable adjustment of the redox conditions during firing. In addition, the effect of maximum firing temperature on microstructural characteristics was evaluated.

    Drought-induced agricultural loss is one of the leading weather-related harms to the U.S. economy, but little is known about the effects of extreme droughts or of consecutive multi-year drought events on agriculture. Three droughts in the early 1930s make the Dust Bowl era the driest and hottest for agriculture in modern U.S. history and a useful analog to study extreme weather and its impact on human society. Improvements in technology and farm management over the last eight decades have dramatically increased average crop yields in the U.S., but the elimination of most non-climatic crop stresses means rainfed yields are now more tightly linked to climate. To understand how a 1930s-type drought would affect agriculture in the modern U.S., we drive empirical and biophysical process-based crop models with 1930s weather -- with and without increases in mean temperature -- to estimate effects of successive droughts on current and near-future U.S. maize, soy and wheat production. Our results suggest that Dust-Bowl-type droughts today would have unprecedented consequences for agricultural productivity, with single-year losses up to ~50% larger than the central U.S. drought of 2012, one of the most severe for modern agriculture. Sensitivity tests imply that damages at these extremes are highly sensitive to temperature. If extreme drought conditions are even modestly warmer (1-4 oC), single-year losses jump to more than twice the 2012 drought. Assuming that repeated crop failure over a relatively short period is likely to induce changes to land-use and management, we find that a future Dust-Bowl-like drought, especially under higher temperature scenarios, could lead to significant long-term consequences for U.S. agriculture. Changes in climate may increase the severity and frequency of future droughts, so understanding the complex interactions of weather extremes and a changing agricultural system is critical to effective preparation and response if and when the next Dust

    Full Text Available In this paper some results concerning the evolution of 3D fluid flow pattern through all four strokes in combustion chambers with entirely different bowl-in-piston geometry layouts ranging from ”omega” to “simple cylinder” were presented. All combustion chambers i.e. those with „omega“ bowls, with different profiles, and those with „cylinder“ bowls, with different squish area ranging from 44% to 62%, were with flat head, vertical valves and identical elevation of intake and exhaust ports. A bunch of results emerged by dint of multidimensional modeling of nonreactive fluid flow in arbitrary geometry with moving objects and boundaries. The fluid flow pattern during induction and compression in all cases was extremely complicated and entirely three-dimensional. It should be noted that significant differences due to geometry of the bowl were encountered only in the vicinity of TDC. Namely, in the case of “omega” bowl all three types of organized macro flows were observed while in the case of “cylinder” bowl no circumferential velocity was registered at all. On the contrary, in the case of “cylinder” bowl some interesting results concerning reverse tumble and its center of rotation shifting from exhaust valve zone to intake valve zone during induction stroke and vice-verse from intake valve zone to exhaust valve zone during compression were observed while in the case of “omega” bowl no such a displacement was legible. During expansion the fluid flow pattern is fully controlled by piston motion and during exhaust it is mainly one-dimensional, except in the close proximity of exhaust valve. For that reason it is not affected by the geometry of the bowl.

    Colloidal particles with two or more different surface properties (Janus particles) are of interest in catalysis, biological imaging, and drug delivery. Eccentric nanoparticles are a type of Janus particle consisting of a shell that envelops the majority of a core particle, leaving a portion of the core surface exposed. Previous work to synthesize eccentric nanoparticles from silica and polystyrene have only used microemulsion techniques. In contrast we report the solgel synthesis of eccentric Janus nanoparticles composed of a silica shell around a carboxylate-modified polystyrene core (Janus templates). In addition, we have synthesized nano-bowl-like structures after the removal of the polystyrene core by organic solvent. These Janus templates and nanobowls can be used as a versatile platform for site-specific functionalization or controlled theranostic delivery. PMID:25431230

  10. Buckled circular monolayer graphene: a graphene nano-bowl

    International Nuclear Information System (INIS)

    We investigate the stability of circular monolayer graphene subjected to a radial load using non-equilibrium molecular dynamics simulations. When monolayer graphene is radially stressed, after some small circular strain (∼0.4%) it buckles and bends into a new bowl-like shape. Young's modulus is calculated from the linear relation between stress and strain before the buckling threshold, which is in agreement with experimental results. The prediction of elasticity theory for the buckling threshold of a radially stressed plate is presented and its results are compared to the one of our atomistic simulation. The Jarzynski equality is used to estimate the difference between the free energy of the non-compressed states and the buckled states. From a calculation of the free energy we obtain the optimum radius for which the system feels the minimum boundary stress.

    Full Text Available In recent years bowl traps have gained attention as a useful method for sampling bees and are now commonly used across the world for this purpose. However, specific questions about the method itself have not yet been tested on different regions of the globe. We present the preliminary results of bowl trapping in a Semidecidual Seasonal forest fragment in southern Brazil, including the test of two different color bowls, two different habitats, and the interaction of these variables in bee species number and composition. We used blue and yellow bowls in the border and in the core trails of the forest fragment. In five sampling days between October to December bowl traps captured 745 specimens of 37 morphospecies, with Halictinae bees being the richest and most abundant group. Non parametrical statistical analyses suggested that different colors of bowl traps influenced bee richness and composition and thus, they should be used together for a more complete sampling. Different trails influenced only the composition, while the interaction with different colors did not have a significant effect. These results, as well as the higher taxonomic composition of the inventoried bees, are similar to other studies reported in the literature.

  15. Evaluation of American Indian Science and Engineering Society Intertribal Middle School Science and Math Bowl Project

    2013-09-25

    The American Indian Science and Engineering Society (AISES) has been funded under a U.S. Department of Energy (DOE) grant (Grant Award No. DE-SC0004058) to host an Intertribal Middle-School Science and Math Bowl (IMSSMB) comprised of teams made up of a majority of American Indian students from Bureau of Indian Education-funded schools and public schools. The intent of the AISES middle school science and math bowl is to increase participation of American Indian students at the DOE-sponsored National Science Bowl. Although national in its recruitment scope, the AISES Intertribal Science and Math Bowl is considered a “regional” science bowl, equivalent to the other 50 regional science bowls which are geographically limited to states. Most regional bowls do not have American Indian student teams competing, hence the AISES bowl is meant to encourage American Indian student teams to increase their science knowledge in order to participate at the national level. The AISES competition brings together teams from various American Indian communities across the nation. Each team is provided with funds for travel to and from the event, as well as for lodging and meals. In 2011 and 2012, there were 10 teams participating; in 2013, the number of teams participating doubled to 20. Each Science and Math Bowl team is comprised of four middle school — grades 6 through 8 — students, one alternate, and a teacher who serves as advisor and coach — although in at least two cases, the coach was not a teacher, but was the Indian Education Coordinator. Each team member must have at least a 3.0 GPA. Furthermore, the majority of students in each team must be comprised of American Indian, Alaska Native or Native Hawaiian students. Under the current DOE grant, AISES sponsored three annual middle school science bowl competitions over the years 2011, 2012 and 2013. The science and math bowls have been held in late March concurrently with the National American Indian Science and

The corrosion products were characterised by energy dispersive X-ray fluorescence spectrometry (EDXRF), Raman spectroscopy and scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS). The last technique was also used to determine the chemical composition of the alloy. The metallographic analysis showed that the bowl was obtained from a monophasic bronze alloy, containing about 11% tin and other elements in traces. The presence of an inhomogeneous microstructure with both thermal twin bands and slip lines was consistent with multiple hammering steps followed by partial annealing treatments. On the bowl a very limited chloride contamination was observed and chlorides were never detected in proximity to the metal. These findings and the morphological/compositional characteristics of the patinas permitted to classify that on the internal side of the bowl as a modified Type I morphology, while the patina on the external side of the bowl was less compact, so that it was judged borderline between a “noble” patina and a disfiguring one.

  18. Quantifying elbow extension and elbow hyperextension in cricket bowling: a case study of Jenny Gunn.

    Science.gov (United States)

    King, Mark A; Yeadon, Maurice R

    2012-05-01

    In this study a method for determining elbow extension and elbow abduction for a cricket bowling delivery was developed and assessed for Jenny Gunn who has hypermobility in both elbows and whose bowling action has been repeatedly queried by umpires. Bowling is a dynamic activity which is assessed visually in real time in a cricket match by an umpire. When the legality of a bowler's action is questioned by an umpire a quantitative analysis is undertaken using a marker based motion analysis system. This method of quantifying elbow extension should agree with a visual assessment of when the arm is "straight" and should minimise the effects of marker movement. A set of six markers on the bowling arm were used to calculate elbow angles. Differences of up to 1° for elbow extension and up to 2° for elbow abduction were found when angles calculated from the marker set for static straight arm trials were compared with measurements taken by a chartered sports physiotherapist. In addition comparison of elbow extension angles at ball release calculated from the markers during bowling trials with those measured from high speed video also showed good agreement with mean differences of 0°±2°.

  19. The effect of a flexed elbow on bowling speed in cricket.

    Science.gov (United States)

    Marshall, Robert; Ferdinands, René

    2003-01-01

    The laws of bowling in cricket state 'a ball is fairly delivered in respect of the arm if, once the bowler's arm has reached the level of the shoulder in the delivery swing, the elbow joint is not straightened partially or completely from that point until the ball has left the hand'. Recently two prominent bowlers, under suspicion for transgressing this law, suggested that they are not 'throwing' but due to an elbow deformity are forced to bowl with a bent bowling arm. This study examined whether such bowlers can produce an additional contribution to wrist/ball release speed by internal rotation of the upper arm. The kinematics of a bowling arm were calculated using a simple two-link model (upper arm and forearm). Using reported internal rotation speeds of the upper arm from baseball and waterpolo, and bowling arm kinematics from cricket, the change in wrist speed was calculated as a function of effective arm length, and wrist distance from the internal rotation axis. A significant increase in wrist speed was noted. This suggests that bowlers who can maintain a fixed elbow flexion during delivery can produce distinctly greater wrist/ball speeds by using upper arm internal rotation. PMID:14658246

    2016-06-01

    The objective of the study was to evaluate two types of cricket bowling techniques by comparing the lumbar spinal loading using a musculoskeletal modelling approach. Three-dimensional kinematic data were recorded by a Vicon motion capture system under two cricket bowling conditions: (1) participants bowled at their absolute maximal speeds (max condition), and (2) participants bowled at their absolute maximal speeds while simultaneously forcing their navel down towards their thighs starting just prior to ball release (max-trunk condition). A three-dimensional musculoskeletal model comprised of the pelvis, sacrum, lumbar vertebrae and torso segments, which enabled the motion of the individual lumbar vertebrae in the sagittal, frontal and coronal planes to be actuated by 210 muscle-tendon units, was used to simulate spinal loading based on the recorded kinematic data. The maximal lumbar spine compressive force is 4.89 ± 0.88BW for the max condition and 4.58 ± 0.54BW for the max-trunk condition. Results showed that there was no significant difference between the two techniques in trunk moments and lumbar spine forces. This indicates that the max-trunk technique may not increase lower back injury risks. The method proposed in this study could be served as a tool to evaluate lower back injury risks for cricket bowling as well as other throwing activities. PMID:26343905

    1999-07-01

    As part of a study being conducted for the Electric Power Research Institute's (EPRI's) Upgraded Coal Interest Group (UCIG) to evaluate ultrafine coal dewatering technologies, testing was carried out to investigate the use of a solid-bowl (high-g) centrifuge for thickening ultrafine coalwater slurries. The objective of this study was to increase the solids concentration to a level suitable for use as a coal-water slurry fuel, while maximizing overall solids recovery. Feed material was collected from the combined discharge (centrate) streams from several screen-bowl centrifuges. These devices are currently being used in a commercial coal cleaning facility to dewater the clean coal product from a froth flotation circuit. Current plant practice is to discharge the centrate to settling ponds. The screen bowl centrate averages 5% solids by weight and contains nearly 60% material finer than 10 {mu}m. The current study examined the effects of operating conditions on centrifuge performance. The test conditions included centrifuge bowl and scroll speeds and volumetric feed rate. In addition to thickening, some cleaning was also achieved, because the finest particles (e.g. < 3 {micro}m), which contained a large percentage of liberated clays, were removed with the bulk of the water. The centrifuge products were analyzed for solids concentration, particle size distribution, and ash content. Size selectivity curves were also used to evaluate centrifuge performance.

    Beach, Aaron J; Ferdinands, René E D; Sinclair, Peter J

    2016-09-01

    Spin bowling is generally coached using a standard technical framework, but this practice has not been based upon a comparative biomechanical analysis of leg-spin and off-spin bowling. This study analysed the three-dimensional (3D) kinematics of 23 off-spin and 20 leg-spin bowlers using a Cortex motion analysis system to identify how aspects of the respective techniques differed. A multivariate ANOVA found that certain data tended to validate some of the stated differences in the coaching literature. Off-spin bowlers had a significantly shorter stride length (p = 0.006) and spin rate (p = 0.001), but a greater release height than leg-spinners (p = 0.007). In addition, a number of other kinematic differences were identified that were not previously documented in coaching literature. These included a larger rear knee flexion (p = 0.007), faster approach speed (p < 0.001), and flexing elbow action during the arm acceleration compared with an extension action used by most of the off-spin bowlers. Off-spin and leg-spin bowlers also deviated from the standard coaching model for the shoulder alignment, front knee angle at release, and forearm mechanics. This study suggests that off-spin and leg-spin are distinct bowling techniques, supporting the development of two different coaching models in spin bowling. PMID:27126895

    The purpose of this study was to determine whether there were changes in death rates when a local football team participated in the Super Bowl. Los Angeles (LA) played in the Super Bowl twice: on January 20, 1980 (LA Rams vs Pittsburgh Steelers, which LA lost), and on January 22, 1984 (LA Raiders vs Washington Redskins, which LA won). Data from LA County were analyzed for all-cause and circulatory death rates for the Super Bowl and the following 14 days when LA played (Super Bowl-related days) and control days (from January 15 to the end of February for 1980 to 1983 and 1984 to 1988). The Super Bowl-related days during LA's losing 1980 game were associated with higher daily death rates in LA County (per 100,000 population) for all deaths (2.4482 vs 2.0968 for control days, p intensity of a game played by a sports team in a highly publicized rivalry such as the Super Bowl can trigger total and cardiovascular deaths.

    Full Text Available Background  To construct a sophisticated three-dimensionalframework, numerousmodifications have been reported in the literature. However, mostsurgeons have paid little attentionto the anatomical configuration of the concha and more to its deepness and hollowness,leading to unsatisfactory outcomes.Methods  For a configuration ofthe concha thatis definitely anatomical,the authorfurtherdeveloped and employed the conchal bowl element,which has been used by severalsurgeonsalthough the results have not been published elsewhere. The author constructed the conchalbowl element in one of three patterns according to the amount of available cartilages: oneblock,two-pieces, or a cymba bowl element only. A total of 20 patients underwent auricularreconstruction using a costal cartilage framework between 2009 and 2012. The 8 earliestreconstructionswere performedwithout a conchal bowl element and the latter 12with a conchalbowl element. The patientswere followed up for more than 1 year. The aesthetic resultswerescored by evaluating characteristicsinvolving the stability ofthe crus helicis,the conchal definition, and the smoothness ofthe helical curve.Results  The earsreconstructed earlywithout a conchal bowl elementshowed a shallowandone or two incompletely separated concha with an obliterated cymba conchal space. Theyalso did not have a realistic orsmooth curve ofthe helix because of an unstable crus helicis.However, earsreconstructed laterwith the concha bowl elementshowed a definite crus helicis,deep cymba conchalspace, and smooth helical curve.Conclusions  The construction of the conchal bowl element is simple, not time-consumingprocedure. It is suggested that the conchal bowl element must be constructed and attachedto themain framework for natural configuration ofthe reconstructed ear.

  19. The case for a southeastern Australian Dust Bowl, 1895-1945

    Science.gov (United States)

    Cattle, Stephen R.

    2016-06-01

    Australia has an anecdotal history of severe wind erosion and dust storm activity, but there has been no lasting public perception of periods of extreme dust storm activity in this country, such as that developed in the USA following the Dust Bowl of the 1930s. Newspaper accounts of droughts and dust storms in southeastern (SE) Australia between 1895 and 1945 suggest that, at various times, the scale of these events was comparable to those experienced in the USA Dust Bowl. During this 50-year period, average annual rainfall values in this region were substantially below long-term averages, air temperatures were distinctly warmer, marginal lands were actively cropped and grazed, and rabbits were a burgeoning grazing pest. From the beginning of the Federation Drought of 1895-1902, dust storm activity increased markedly, with the downwind coastal cities of Sydney and Melbourne experiencing dust hazes, dust storms and falls of red rain relatively regularly. Between 1935 and 1945, Sydney and Melbourne received ten and nine long-distance dust events, respectively, with the years of 1938 and 1944/45 being the most intensely dusty. Entire topsoil horizons were blown away, sand drift was extreme, and crops and sheep flocks were destroyed. Although these periods of extreme dust storm activity were not as sustained as those experienced in the USA in the mid-1930s, there is a strong case to support the contention that SE Australia experienced its own extended, somewhat episodic version of a Dust Bowl, with a similar combination of causal factors and landscape effects.

  20. "Hot hand" on strike: bowling data indicates correlation to recent past results, not causality.

    Directory of Open Access Journals (Sweden)

    Gur Yaari

    Full Text Available Recently, the "hot hand" phenomenon regained interest due to the availability and accessibility of large scale data sets from the world of sports. In support of common wisdom and in contrast to the original conclusions of the seminal paper about this phenomenon by Gilovich, Vallone and Tversky in 1985, solid evidences were supplied in favor of the existence of this phenomenon in different kinds of data. This came after almost three decades of ongoing debates whether the "hot hand" phenomenon in sport is real or just a mis-perception of human subjects of completely random patterns present in reality. However, although this phenomenon was shown to exist in different sports data including basketball free throws and bowling strike rates, a somehow deeper question remained unanswered: are these non random patterns results of causal, short term, feedback mechanisms or simply time fluctuations of athletes performance. In this paper, we analyze large amounts of data from the Professional Bowling Association(PBA. We studied the results of the top 100 players in terms of the number of available records (summed into more than 450,000 frames. By using permutation approach and dividing the analysis into different aggregation levels we were able to supply evidence for the existence of the "hot hand" phenomenon in the data, in agreement with previous studies. Moreover, by using this approach, we were able to demonstrate that there are, indeed, significant fluctuations from game to game for the same player but there is no clustering of successes (strikes and failures (non strikes within each game. Thus we were lead to the conclusion that bowling results show correlation to recent past results but they are not influenced by them in a causal manner.

  1. Piston Bowl Optimization for RCCI Combustion in a Light-Duty Multi-Cylinder Engine

    Reactivity Controlled Compression Ignition (RCCI) is an engine combustion strategy that that produces low NO{sub x} and PM emissions with high thermal efficiency. Previous RCCI research has been investigated in single-cylinder heavy-duty engines. The current study investigates RCCI operation in a light-duty multi-cylinder engine at 3 operating points. These operating points were chosen to cover a range of conditions seen in the US EPA light-duty FTP test. The operating points were chosen by the Ad Hoc working group to simulate operation in the FTP test. The fueling strategy for the engine experiments consisted of in-cylinder fuel blending using port fuel-injection (PFI) of gasoline and early-cycle, direct-injection (DI) of diesel fuel. At these 3 points, the stock engine configuration is compared to operation with both the original equipment manufacturer (OEM) and custom machined pistons designed for RCCI operation. The pistons were designed with assistance from the KIVA 3V computational fluid dynamics (CFD) code. By using a genetic algorithm optimization, in conjunction with KIVA, the piston bowl profile was optimized for dedicated RCCI operation to reduce unburned fuel emissions and piston bowl surface area. By reducing these parameters, the thermal efficiency of the engine was improved while maintaining low NOx and PM emissions. Results show that with the new piston bowl profile and an optimized injection schedule, RCCI brake thermal efficiency was increased from 37%, with the stock EURO IV configuration, to 40% at the 2,600 rev/min, 6.9 bar BMEP condition, and NOx and PM emissions targets were met without the need for exhaust after-treatment.

    Unusually hot summer conditions occurred during the 1930s over the central United States and undoubtedly contributed to the severity of the Dust Bowl drought. We investigate local and large-scale conditions in association with the extraordinary heat and drought events, making use of novel datasets of observed climate extremes and climate reanalysis covering the past century. We show that the unprecedented summer heat during the Dust Bowl years was likely exacerbated by land-surface feedbacks associated with springtime precipitation deficits. The reanalysis results indicate that these deficits were associated with the coincidence of anomalously warm North Atlantic and Northeast Pacific surface waters and a shift in atmospheric pressure patterns leading to reduced flow of moist air into the central US. Thus, the combination of springtime ocean temperatures and atmospheric flow anomalies, leading to reduced precipitation, also holds potential for enhanced predictability of summer heat events. The results suggest that hot drought, more severe than experienced during the most recent 2011 and 2012 heat waves, is to be expected when ocean temperature anomalies like those observed in the 1930s occur in a world that has seen significant mean warming.

  10. Three-dimensional æolian dynamics within a bowl blowout during offshore winds: Greenwich Dunes, Prince Edward Island, Canada

    Hesp, Patrick A.; Walker, Ian J.

    2012-01-01

    This paper examines the æolian dynamics of a deep bowl blowout within the foredune of the Greenwich Dunes, on the northeastern shore or Prince Edward Island, Canada. Masts of cup anemometers and sonic anemometers were utilized to measure flow velocities and directions during a strong regional ESE (offshore) wind event. The flow across the blowout immediately separated at the upwind rim crest, and within the blowout was strongly reversed. High, negative vertical flows occurred down the downwind (but seaward) vertical scarp which projected into the separation envelope and topographically forced flow back into the blowout. A pronounced, accelerated jet flow existed near the surface across the blowout basin, and the flow exhibited a complex, anti-clockwise structure with the near-surface flow following the contours around the blowout basin and lower slopes. Significant æolian sediment transport occurred across the whole bowl basin and sediment was delivered by saltation and suspension out the blowout to the east. This study demonstrates that strong offshore winds produce pronounced topographically forced flow steering, separation, reversal, and more complex three-dimensional motions within a bowl blowout, and that such winds within a bowl blowout play a notable role in transporting sediment within and beyond deep topographic hollows in the foredune.

  12. The Byzantine Silver Bowls in the Sutton Hoo Ship Burial and Tree-Worship in Anglo-Saxon England

    Directory of Open Access Journals (Sweden)

    Michael D. J. Bintley

    2011-12-01

    Full Text Available The ten Byzantine silver bowls included amongst the grave goods interred in the chamber of the Mound 1 ship burial at Sutton Hoo remain one of the most puzzling features of this site. It has been suggested that these items, which lay separated from the rest of the silver in the burial and close to the head of the body-space (where no body was found, may have had some special meaning which has never been discovered. This paper will argue that one of the possible keys to unlocking their significance may be found in the central roundel that adorns the centre of each bowl in the form of a rosette. These bowls, which are thought to have been manufactured in the eastern provinces of the Byzantine Empire in c. 600, entered the British Isles in unknown circumstances before coming into the possession of the man buried in (or commemorated by the Mound 1 burial. Through comparison with contemporary sculpture and vernacular literature, I will suggest that this central rosette, which was associated with both the cross of Christ and sacred trees in Byzantine sculpture, may have served as a conventional bridge between Christian and pre-Christian religious traditions associated with sacred trees in Anglo-Saxon England. The central rosettes adorning each of these bowls may have been understood as the flower of a sacred tree. Since the latter appears to have figured in Anglian paganism it is possible that the bowls may helped to convert the Anglian aristocracy, bridging a gap between Germanic insular religious traditions and those that were being introduced to Britain at the time that the ship burial itself took place.

During which period, Yuan Dynasty was considered a crucial turning-point with great changes. The current tea culture in China is an adoption and innovation of Ming and Qing dynasty, especially in the form of processing technology. For those elements inherited from Tang and Song dynasties, however, they were more directly adopted systematically by Japan. Ever since powdered tea culture from Song dynasty was accepted in Japan, Jianzhan, the tea bowl that gained renowned reputation in the Song tea culture was also introduced and became tenmoku (tianmu after localization. As the transformation of Chinese tea culture ended in Japan, Japanese tea culture of wabi-cha was shaped after the tenmoku’s obvious decline in value.

    Full Text Available The combustion process in the diesel engine should be controlled to avoid both excessive maximum cylinder pressure and an excessive rate of pressure rise, in terms of crank angle. At the same time, the process should be so rapid that substantially all the fuel is burned early in the expansion stroke. In this direction, piston configuration plays a crucial role. Four configurations i.e., flat, inclined, central bowl, and inclined offset bowl piston have been studied. This study is concerned with the CFD analysis has been carried out on two valve four stroke diesel engine to analyze the in-cylinder air motion during suction stroke, pressure and temperature variation inside the cylinder during the compression stroke for various configurations. The engine specifications are considered from the literature. For numerical analysis, Ansys15 CFD software has been used, for meshing polyhedral trimmed cells were adopted. In-cylinder flows were analyzed by solving mass, momentum and energy equation. From this study, it is concluded that analysis has been carried out for each crank angle degree during suction and compression stroke for all the piston configurations, tumble ratio varies mainly with crank angle position. At the end of the compression stroke fuel is injected and the performance of different piston bowls are analyzed.

  16. Singlet-Triplet Transition in Quantum Dots Confined by Triangular and Bowl-Like Potentials: the Effect of Electric Fields

    2005-01-01

    @@ We theoretically investigate the energy spectra of two-electron two-dimensional (2e 2D) quantum dots (QDs)confined by triangular potentials and bowl-like potentials in a magnetic field by exact diagonalization in the framework of effective mass theory. An in-plane electric field is found to contribute to the singlet-triplet transition of the ground state of the 2e 2D QDs confined by triangular or bowl-like potentials in a perpendicular magnetic field. The stronger the in-plane electric field, the smaller the magnetic field for the total spin of the ground states in the dot systems to change from S = 0 to S = 1. However, the influence of anin-plane electric field on the singlettriplet transition of the ground state of two electrons in a triangular QD modulated by a perpendicular magnetic field is quite small because the triangular potential just deviates from the harmonic potential well slightly. We find that the strength of the perpendicular magnetic field needed for the spin singlet-triplet transition of the ground state of the QD confined by a bowl-like potential is reduced drastically by applying an in-plane electric field.

    A chemical bonding model is presented for the bowl-like C5v B30 global-minimum cluster with a central pentagonal hole. The B30 cluster is composed of three concentric boron rings: first B5, second B10, and third B15. The first and second B rings constitute an inner double-chain ribbon and support a delocalized π sextet. The second and third rings form an outer double-chain ribbon, where 14π delocalized electrons are situated. The unique π systems lead to concentric dual π aromaticity for B30, a concept established from concerted computational data on the bases of canonical molecular orbital (CMO) analysis, adaptive natural density partitioning (AdNDP), nucleus-independent chemical shifts (NICS), and natural charge calculations. A proposal is put forward that the bowl-like B30 cluster is an exact all-boron analogue of corannulene (C20H10), a fragment of C60 fullerene. The bonding nature of corannulene is revisited and fully elucidated herein. A comparison of the bonding patterns in bowl-like C5v B30 cluster and two other structural isomers (Cs and C1) unravels the mechanism as to why the defective hole prefers to be positioned at the center.

  18. Spin-bowling in cricket re-visited: model trajectories for various spin-vector angles

    Science.gov (United States)

    Robinson, Garry; Robinson, Ian

    2016-08-01

    In this paper we investigate, via the calculation of model trajectories appropriate to slow bowling in cricket, the effects on the flight path of the ball before pitching due to changes in the angle of the spin-vector. This was accomplished by allowing the spin-vector to vary in three ways. Firstly, from off-spin, where the spin-vector points horizontally and directly down the pitch, to top-spin where it points horizontally towards the off-side of the pitch. Secondly, from off-spin to side-spin where, for side-spin, the spin-vector points vertically upwards. Thirdly, where the spin-vector points horizontally and at 45° to the pitch (in the general direction of ‘point’, as viewed by the bowler), and is varied towards the vertical, while maintaining the 45° angle in the horizontal plane. It is found that, as is well known, top-spin causes the ball to dip in flight, side-spin causes the ball to move side-ways in flight and, perhaps most importantly, off-spin can cause the ball to drift to the off-side of the pitch late in its flight as it begins to fall. At a more subtle level it is found that, if the total spin is kept constant and a small amount of top-spin is added to the ball at the expense of some off-spin, there is little change in the side-ways drift. However, a considerable reduction in the length at which the ball pitches occurs, ∼25 cm, an amount that batsmen can ignore at their peril. On the other hand, a small amount of side-spin introduced to a top-spin delivery does not alter the point of pitching significantly, but produces a considerable amount of side-ways drift, ∼10 cm or more. For pure side-spin the side-ways drift is up to ∼30 cm. When a side-spin component is added to the spin of a ball bowled with a mixture of off-spin and top-spin in equal proportions, significant movement occurs in both the side-ways direction and in the point of pitching, of the order of a few tens of centimetres.

  19. The effect of elbow hyperextension on ball speed in cricket fast bowling.

    Felton, P J; King, M A

    2016-09-01

    This study investigates how elbow hyperextension affects ball release speed in fast bowling. A two-segment planar computer simulation model comprising an upper arm and forearm + hand was customised to an elite fast bowler. A constant torque was applied at the shoulder and elbow hyperextension was represented using a damped linear torsional spring at the elbow. The magnitude of the constant shoulder torque and the torsional spring parameters were determined by concurrently matching three performances. Close agreement was found between the simulations and the performances with an average difference of 3.8%. The simulation model with these parameter values was then evaluated using one additional performance. Optimising ball speed by varying the torsional spring parameters found that elbow hyperextension increased ball release speed. Perturbing the elbow torsional spring stiffness indicated that the increase in ball release speed was governed by the magnitude of peak elbow hyperextension and the amount that the elbow recoils back towards a straight arm after reaching peak elbow hyperextension. This finding provides a clear understanding that a bowler who hyperextends at the elbow and recoils optimally will have an increase in ball speed compared to a similar bowler who cannot hyperextend. A fast bowler with 20° of elbow hyperextension and an optimal level of recoil will have increased ball speeds of around 5% over a bowler without hyperextension. PMID:26821838

  20. The effect of marker placement around the elbow on calculated elbow extension during bowling in cricket.

    2015-01-01

    The elbow extension angle during bowling in cricket may be calculated from the positions of markers attached around the shoulder, elbow and wrist using an automated laboratory-based motion analysis system. The effects of two elbow-marker sets were compared. In the first, a pair of markers was placed medially and laterally close to the condyles while in the second a triad of markers was placed on the back of the upper arm close to the elbow. The root mean square (RMS) difference in elbow extension angle between the two methods at four key instants was 8° for 12 fast bowlers and 4° for 12 spin bowlers. When evaluated against video estimates of the elbow extension angle for the fast bowlers, the elbow extension angle calculated using the pair method had an RMS error of 2° while the triad method had an RMS error of 8°. The corresponding errors for the spin bowlers were 3° and 5°, respectively. It is thought that the greater errors associated with the triad is a consequence of soft tissue movement in this dynamic activity. This is consistent with the finding of greater error for the fast bowlers compared with the spin bowlers. PMID:25682835

  1. A Unified Framework for Producing CAI Melting, Wark-Lovering Rims and Bowl-Shaped CAIs

    Liffman, Kurt; Paterson, David A

    2016-01-01

    Calcium Aluminium Inclusions (CAIs) formed in the Solar System, some 4,567 million years ago. CAIs are almost always surrounded by Wark-Lovering Rims (WLRs), which are a sequence of thin, mono/bi-mineralic layers of refractory minerals, with a total thickness in the range of 1 to 100 microns. Recently, some CAIs have been found that have tektite-like bowl-shapes. To form such shapes, the CAI must have travelled through a rarefied gas at hypersonic speeds. We show how CAIs may have been ejected from the inner solar accretion disc via the centrifugal interaction between the solar magnetosphere and the inner disc rim. They subsequently punched through the hot, inner disc rim wall at hypersonic speeds. This re-entry heating partially or completely evaporated the CAIs. Such evaporation could have significantly increased the metal abundances of the inner disc rim. High speed movement through the inner disc produced WLRs. To match the observed thickness of WLRs required metal abundances at the inner disc wall that a...

    Structural colors of the ordered photonic nanostructures are widely used as an effective platform for manipulating the propagation of light. Although several approaches have been explored in attempts to mimic the structural colors, improving the reproducibility, mechanical stability, and the economic feasibility of sophisticated photonic crystals prepared by complicated processes continues to pose a challenge. In this study, we report on an alternative, simple method for fabricating a tunable photonic crystal at room temperature. A bowl-like nanostructure of TiO2 was periodically arranged on a thin Ti sheet through a two-step anodization process where its diameters were systemically controlled by changing the applied voltage. Consequently, they displayed a broad color distribution, ranging from red to indigo, and the principal reason for color generation followed the Bragg diffraction theory. This noncolorant method was capable of reproducing a Mondrian painting on a centimeter scale without the need to employ complex architectures, where the generated structural colors were highly stable under mechanical or chemical influence. Such a color printing technique represents a potentially promising platform for practical applications for anticounterfeit trademarks, wearable sensors, and displays. PMID:27245939

    As a result of increases in CO{sub 2} and other radiatively important trace gases, scientists have predicted increases in mean worldwide temperatures of 2--5 degrees C over the next 50 to 100 years. Such temperature increases may result in climate modifications that would in turn be associated with increases in drought and desertification and could even change the patterns of the monsoons and tropical rains, which are important to agriculture throughout the world. They predicted that the rise in sea level caused by melting and thermal expansion of glaciers and polar icecaps could flood large population centers, destroying habitation and displacing populations. This will result in approximately 50 million ``environmental refugees`` worldwide, triple the number of today. The expected shifts in precipitation are also likely to result in (1) increased runoff contaminated with pesticides, salts, garbage, sewage, and eroded soil, and (2) drought also leading to increased soil erosion and salinization, as well as depletion of limited water resources. The total impact of global warming on agriculture and human habitation could considerably slow the economic development of some nations and would particularly affect agricultural production. Loss of homes, the inability to raise food, an increased prevalence of disease and worsened economic conditions may drive people to leave their homelands, seeking entry into countries which have more resources and greater resistance to the economic consequences of climatic change. This report looks at the possible environmental impacts and economic impacts of the greenhouse effect on Mexico while using the American Dust Bowl event as an analog.

    Bring telescope to where the people are! Music and Astronomy Under the Stars (MAUS) is a NASA-funded as astronomy outreach program at community parks and music festivals (1000 - 25,000 people/event). While there have been many astronomy outreach activities and telescope observations at sidewalks and parks, this program targets a different audience - music lovers who are attending concerts in community parks or festivals. These music lovers who may not have visited science museums, planetariums, or star parties are exposed to telescope observations and astronomy information with no additional travel costs. MAUS includes solar observing, telescope observations including a live imaging system, an astronomical video, astronomy banners/posters, and hands-on activities. MAUS increased awareness, engagement, and interest in astronomy at classical, pop, rock, and ethnic music concerts. Since 2009 over 50,000 people have participated in these outreach activities including a significant number of families and young girls. In addition to concerts in local Long Island parks, there were MUAS events at Tanglewood (summer home of the Boston Symphony Orchestra), Jazz in Central Park, and Astronomy Night on the National Mall (co-sponsored by the White House Office of Science and Technology Policy). In 2011 MUAS will be expanded to include Ravinia (summer home of the Chicago Symphony Orchestra), the Newport Folk Festival, and the Bethel Woods Center for the Arts (site of the 1969 Woodstock festival). According to our survey results, music lovers became more informed about astronomy. Expanding Hofstra University's successful outreach programs, I propose the creation of a National Halloween Stars event targeting children and a National Super Bowl Star Party targeting girls, women, and the 2/3 of Americans who do not watch the Super Bowl. This can be combined with astronomers or amateur astronomers bringing telescopes to Super Bowl parties for football fans to stargaze during

  5. Synthesis of bowl-like mesoporous LiFePO4/C composites as cathode materials for lithium ion batteries

    International Nuclear Information System (INIS)

    Mesoporous bowl-like LiFePO4/C composites were synthesized by a wet milling-spray drying-carbothermal reduction (WSC) using starch as the organic carbon source and reductive agent. The samples were examined by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Brunauer-Emmett-Teller (BET) analysis, cyclic voltammograms (CV), electrochemical impedance spectra (EIS) and galvanostatic charge–discharge testing. Most of the mesoporous bowl-like LiFePO4/C composites with particle size in the range 5–10 μm, coated with evenly distributed carbon, were assembled by nanoparticles (2 g−1. These delivered a discharge capability of 123 mAh g−1 at 10 C, with no capacity loss after 100 cycles. The enhanced electrochemical performance was mainly ascribed to the improved ionic/electronic conductivity and structural stability arising from the interconnected mesoporous pores, carbon-coated nanoparticles and micro-sized structure

    The process parameters of aluminum alloy ladder bowl with viscous pressure forming and solid metal punch forming were numerically simulated by commercial finite element software DEFORM.The influence of blank holder pressure(BHP)on the formability of sheet metal was investigated.It was found that lower BHP does benefit to the distribution of thickness both with VPF and with solid punch forming.The forming force needed in VPF is bigger than that of with solid punch forming at the same stroke.The distribution of thickness with VPF is more uniform than that of with solid punch forming.Compared with solid punch forming,the damage values of workpiece at the top convex comer are lower by VPF.It was also shown that fracture tendency could be reduced with VPF,so that means the formability is improved.At the same time,aluminum alloy ladder bowl was manufactured with VPF.The results show that the simulation results are in agreement with the experimental data very well.

    The properties of diamond like carbon (DLC) films grown in modified microwave plasma CVD reactor is presented in this paper. By using bowl shaped steel substrate holder in a MW plasma CVD reactor (without ECR), films have been grown at relatively high pressure (20Torr) and at low temperature (without heating). The input microwave power was about 300W. Earlier, under the same growth conditions, no deposition was achieved when flat molybdenum/steel substrate holders were used. In this study, two different designs of bowl shaped steel substrate holder at different bias have been experimented. Raman spectra confirm the DLC characteristics of the films. FTIR results indicate that the carbon is bonded in the 3 form with hydrogen, and this characteristic is more pronounced when smaller holder is used. UV-visible spectra show high visible transmittance (∼85%) for films grown in both the holders. The nanoindentation hardness of the films have a wide range, about 4–16GPa. Field emission scanning electron microscope (FESEM) images reveal that the films have featureless and smooth surface morphology. These films are polymeric in nature with moderately high hardness, which may be useful as anti-scratch and anti-corrosive coatings.

In baseline, the ratio of TEI to recommended total energy intake (RTR of OW and OB were higher than that of NW. The PCI of HC was higher than that of LC and alcohol intake of HC was lower than that of LC. After education, the reduction of RTREI in OB was higher than that in OW and NW. The reduction of PCI in HC was higher than that of LC.ConclusionA small rice bowl based meal plan was effective for the reduction of energy intake and control of marcronutrient intake in Korean obese men with type 2 diabetes consuming a high carbohydrate diet.

  9. Li and Na storage behavior of bowl-like hollow Co3O4 microspheres as an anode material for lithium-ion and sodium-ion batteries

    International Nuclear Information System (INIS)

    Highlights: • A unique bowl-like hollow spherical Co3O4 structure is prepared through a simple, low-cost and mass-yield method. • Such a bowl-like hollow Co3O4 microsphere demonstrates extraordinary rate and cycling performance for Li-storage. • The sodium-storage behavior of Co3O4 is investigated for the first time. - Abstract: Bowl-like hollow Co3O4 microspheres are prepared via a simple and low-cost route by thermally treating Co-containing resorcinol-formaldehyde composites gel in air. Scanning electron microscopy, transmission electron microscope and N2 adsorption-desorption measurements demonstrate that these bowl-like hollow Co3O4 microspheres are composed of hollow inner cavities and outer shell walls (70 nm thickness), on which a considerable amount of mesopores centered around 5-17 nm size are distributed. When employed as the anode material for lithium-ion batteries, these bowl-like hollow Co3O4 microspheres exhibit extraordinary cycling performance (111% retention after 50 cycles owing to capacity rise), fairly high rate capacity (650 mAh g−1 at 5 C) and enhanced lithium storage capacity. Meanwhile, the Na-storage behavior of Co3O4 as an anode material of Na-ion batteries is initially investigated based on such a hollow structure and it exhibits similar feature of discharge/charge profiles and a high initial discharge capacity but relatively moderate capacity retention compared with the Li-storage performance

    Supramolecular coordination cages and polymers bear exceptional advantages over their organic counterparts. They are available in one-pot reactions and in high yields and display physical properties that are generally inaccessible with organic species. Moreover, their weak, reversible, noncovalent bonding interactions facilitate error checking and self-correction. This review emphasizes the achievements in supramolecular coordination container as well as polymer chemistry initiated by serendipity and their materialization based on rational design. The recognition of similarities in the synthesis of different supramolecular assemblies allows prediction of potential structures in related cases. The combination of detailed symmetry considerations with the basic rules of coordination chemistry has only recently allowed for the design of rational strategies for the construction of a variety of nanosized spherical containers, bowls, 1D-, 2D-, and 3D-coordination polymers with specified size and shape.

    In order to meet the technical requirements of grinding the circumferential cutting edge of indexable inserts, thermo-mechanical properties of bowl-shaped grinding wheel in high speed grinding process and the influence of dimension variations of the grinding wheel on machining accuracy were investigated. Firstly, the variation trends of the dimension due to centrifugal force generated in different wheel speeds were studied and the effect of stress stiffening and spin softening was presented. Triangular heat flux distribution model was adopted to determine temperature distribution in grinding process. Temperature field cloud pictures were obtained by the finite element software. Then, dimension variation trends of wheel structure were acquired by considering the thermo-mechanical characteristic under combined action of centrifugal force and grinding heat at different speeds. A method of online dynamic monitoring and automatic compensation for dimension error of indexable insert was proposed. By experimental verification, the precision of the inserts satisfies the requirement of processing.

    Super Bowl XLIX took place on February 1, 2015, in Glendale, Arizona. In preparation for this event and associated activities, the Maricopa County Department of Public Health (MCDPH) developed methods for enhanced surveillance, situational awareness, and early detection of public health emergencies. Surveillance strategies implemented from January 22 to February 6, 2015, included enhanced surveillance alerts; animal disease surveillance; review of NFL clinic visits; syndromic surveillance for emergency room visits, urgent care facilities, and hotels; real-time onsite syndromic surveillance; all-hazards mortality surveillance; emergency medical services surveillance, review of poison control center reports; media surveillance; and aberration detection algorithms for notifiable diseases. Surveillance results included increased influenzalike illness activity reported from urgent care centers and a few influenza cases reported in the NFL clinic. A cyanide single event exposure was investigated and determined not to be a public health threat. Real-time field syndromic surveillance documented minor injuries at all events and sporadic cases of gastrointestinal and neurological (mostly headaches) disease. Animal surveillance reports included a cat suspected of carrying plague and tularemia and an investigation of highly pathogenic avian influenza in a backyard chicken flock. Laboratory results in both instances were negative. Aberration detection and syndromic surveillance detected an increase in measles reports associated with a Disneyland exposure, and syndromic surveillance was used successfully during this investigation. Coordinated enhanced epidemiologic surveillance during Super Bowl XLIX increased the response capacity and preparedness of MCDPH to make informed decisions and take public health actions in a timely manner during these mass gathering events.

    High-efficient, plasmon-enhanced nonlinear phenomena based on hybrid nanostructures, which combine nonlinear dielectrics with plasmonic metals, are of fundamental importance for various applications ranging from all-optical switching to imaging or bio-sensing. However, the high loss of the excitation energy in nanostructures and the poor spatial overlap between the plasmon enhancement and the bulk of nonlinear materials largely limit the operation of plasmon-enhanced nonlinear effects, resulting in low nonlinear conversion efficiency. Here, we design and fabricate a ZnO-covered, 2D silver-bowl array, which can serve as an efficient platform for plasmon-enhanced second-harmonic generation (PESHG). Validated by experiments and simulations, we demonstrate that the high spatial overlap between the near-field enhancement and the ZnO film plays the key role for this nanostructure-based PESHG process. The enhancement mainly originates from the fundamental wavelength-derived plasmon resonance, providing an enhancement factor of approximately 33 times. These results achieved pave the way for future applications, which require localized light sources at nanoscale. PMID:27145724

  4. An experimental investigation on the influence of piston bowl geometry on RCCI performance and emissions in a heavy-duty engine

    International Nuclear Information System (INIS)

    Highlights: • Great influence of piston geometry at low load using single injection strategies. • Enhanced combustion development at mid load through optimized piston surface area. • Double injection allows ultra-low NOx and soot levels for the three piston geometries. • Unacceptable soot emissions at high load using single injection and bathtub geometry. • Stepped geometry leads to ultra-clean combustion with lower fuel consumption than CDC. - Abstract: This experimental work investigates the effects of piston bowl geometry on RCCI performance and emissions at low, medium and high engine loads. For this purpose three different piston bowl geometries with compression ratio 14.4:1 have been evaluated using single and double injection strategies. The experiments were conducted in a heavy-duty single-cylinder engine adapted for dual fuel operation. All the tests were carried out at 1200 rev/min. Results suggest that piston geometry has great impact on combustion development at low load conditions, more so when single injection strategies are used. It terms of emissions, it was proved that the three geometries enables ultra-low NOx and soot emissions at low and medium load when using double injection strategies. By contrast, unacceptable emissions were measured at high load taking into account EURO VI limitations. Finally, the application of a mathematical function considering certain self-imposed constraints suggested that the more suitable piston geometry for RCCI operation is the stepped one, which has a modified transition from the center to the squish region and reduced piston surface area than the stock geometry

    A new test bench has been sup up and equipped in order to analyze the air mean motion and turbulence quantities in the combustion system of an automotive diesel engine with one helicoidal intake duct and a conical type in-piston bowl. A sophisticated HWA technique employing single- and dual-sensor probes was applied to the in-cylinder flow investigation under motored conditions. The anemometric probe was also operated as a thermometric sensor. An analytical-numerical procedure, based on the heat balance equations for both anemometric and thermometric wires, was refined and applied to compute the gas velocity from the anemometer output signal. The gas property influence, the thermometric sensor lag and the prong temperature effects were taken into account with this procedure. The in-cylinder velocity data were reduced using both a cycle-resolved approach and the conventional ensemble-averaging procedure, in order to separate the mean flow from the fluctuating motion. New results on the statistical properties of the non-stationary engine turbulence, with particular reference to its time-frequency spectral structure, were obtained at practical engine speeds, in the range of 600--3,000 rpm, and at different locations along the injector axis, one of which was very close to the cylinder-head wall.

    Crop fraction is the ratio of crop occupying a unit area in ground pixel, is very important for monitoring crop growth. One of the most important variables in crop growth monitoring is the fraction of available solar radiation intercepted by foliage. Late blight of potato (Solanum tuberosum), caused by the oomycete pathogen Phytophthora infestans, is considered to be the most destructive crop diseases of potato worldwide. Under favourable climatic conditions, and without intervention (i.e. fungicide sprays), the disease can destroy potato crop within few weeks. Therefore it is important to evaluate the crop fraction for monitoring the healthy and late blight affected potato crops. This study was conducted in potato bowl of West Bengal, which consists of districts of Hooghly, Howrah, Burdwan, Bankuara, and Paschim Medinipur. In this study different crop fraction estimation method like linear spectral un-mixing, Normalized difference vegetation index (NDVI) based DPM model (Zhang et al. 2013), Ratio vegetation index based DPM model, improved Pixel Dichotomy Model (Li et al. 2014) ware evaluated using multi-temporal IRS AWiFs data in two successive potato growing season of 2012-13 and 2013-14 over the study area and compared with measured crop fraction. The comparative study based on measured healthy and late blight affected potato crop fraction showed that improved Pixel Dichotomy Model maintain the high coefficient of determination (R2= 0.835) with low root mean square error (RMSE=0.21) whereas the correlation values of NDVI based DPM model and RVI based DPM model is 0.763 and 0.694 respectively. The changing pattern of crop fraction profile of late blight affected potato crop was studied in respect of healthy potato crop fraction which was extracted from the 269 GPS points of potato field. It showed that the healthy potato crop fraction profile maintained the normal phenological trend whereas the late blight affected potato crop fraction profile suddenly fallen

  13. Energy dispersive X-ray fluorescence spectroscopy/Monte Carlo simulation approach for the non-destructive analysis of corrosion patina-bearing alloys in archaeological bronzes: The case of the bowl from the Fareleira 3 site (Vidigueira, South Portugal)

    International Nuclear Information System (INIS)

    Energy dispersive X-ray fluorescence (EDXRF) is a well-known technique for non-destructive and in situ analysis of archaeological artifacts both in terms of the qualitative and quantitative elemental composition because of its rapidity and non-destructiveness. In this study EDXRF and realistic Monte Carlo simulation using the X-ray Monte Carlo (XRMC) code package have been combined to characterize a Cu-based bowl from the Iron Age burial from Fareleira 3 (Southern Portugal). The artifact displays a multilayered structure made up of three distinct layers: a) alloy substrate; b) green oxidized corrosion patina; and c) brownish carbonate soil-derived crust. To assess the reliability of Monte Carlo simulation in reproducing the composition of the bulk metal of the objects without recurring to potentially damaging patina's and crust's removal, portable EDXRF analysis was performed on cleaned and patina/crust coated areas of the artifact. Patina has been characterized by micro X-ray Diffractometry (μXRD) and Back-Scattered Scanning Electron Microscopy + Energy Dispersive Spectroscopy (BSEM + EDS). Results indicate that the EDXRF/Monte Carlo protocol is well suited when a two-layered model is considered, whereas in areas where the patina + crust surface coating is too thick, X-rays from the alloy substrate are not able to exit the sample. - Highlights: • EDXRF/Monte Carlo simulation is used to characterize an archeological alloy. • EDXRF analysis was performed on cleaned and patina coated areas of the artifact. • EDXRF/Montes Carlo protocol is well suited when a two-layered model is considered. • When the patina is too thick, X-rays from substrate are unable to exit the sample

    The adsorption and the redox processes of two first-generation salicylaldiamine dendritic ligands and their copper, cobalt and nickel metallo-functionalized complexes have been studied at two types of carbon electrode surface. Glassy carbon (GC) was used in an electrochemistry study and highly oriented pyrolitic graphite (HOPG) in ex situ atomic force microscopy (AFM) imaging. All salicylaldimine ligands and their metallo-functionalized complexes adsorb on the surface of the HOPG electrode, resulting in the formation of nanoclusters and films, which vary between 0.9 and 6 nm in size, depending on the metallo-functionalized salicylaldimine dendrimer chemical composition and solution concentration. Differential pulse voltammetry of the surface-confined films has shown that the anodic reactions observed correspond to the oxidation of the hydroxyl groups present in the ligand structure of all compounds. However, by following the changes in peak currents, potentials and width at half height it has been shown that destabilization of the ligand internal structure occurred in the metallo-functionalized complexes depending on the metal involved. The electrochemical behaviour of the surface-confined films observed in buffer solution was related to the morphology, obtained by AFM, of the immobilised first-generation salicylaldiamine dendritic ligands and corresponding salicylaldimine metallo-functionalized complexes.

    1,4,8,11-Tetraazabicyclo[6.6.2]hexadecane-4,11-diacetic acid (CB-TE2A) is of much interest in nuclear medicine for its ability to form copper complexes that are kinetically inert, which is beneficial in vivo to minimize the loss of radioactive copper. The structural chemistry of the hydrated HCl salt of CB-TE2A, namely 11-carboxymethyl-1,8-tetraaza-4,11-diazoniabicyclo[6.6.2]hexadecane-4-acetate chloride trihydrate, C16H31N4O4(+)·Cl(-)·3H2O, is described. The compound crystallized as a positively charged zwitterion with a chloride counter-ion. Two of the amine groups in the macrocyclic ring are protonated. Formally, a single negative charge is shared between two of the carboxylic acid groups, while one chloride ion balances the charge. Two intramolecular hydrogen bonds are observed between adjacent pairs of N atoms of the macrocycle. Two intramolecular hydrogen bonds are also observed between the protonated amine groups and the pendant carboxylate groups. A short intermolecular hydrogen bond is observed between two partially negatively charged O atoms on adjacent macrocycles. The result is a one-dimensional polymeric zigzag chain that propagates parallel to the crystallographic a direction. A second intermolecular interaction is a hydrogen-bonding network in the crystallographic b direction. The carbonyl group of one macrocycle is connected through the three water molecules of hydration to the carbonyl group of another macrocycle. PMID:26846499

    This paper describes a simple system for multi-agent delivery. The system consists of a biodegradable polymer particle with a hollow interior, together with a hole on its surface that can be completely or partially sealed via thermal annealing. A hydrophobic dye, Nile-red, entrapped within the shell of hollow particles presents a sustained release behavior while methylene blue, a hydrophilic model agent, encapsulated in the hollow interior shows a fast release manner. The release profiles of the probes can be further independently controlled by encapsulating methylene blue-loaded polymer nanoparticles, instead of free dye, in the hollow particle with a small hole on its surface.

    This study is aimed at providing a relative comparison of the thermodynamic and economic performance in electric applications for fixed mirror distributed focus (FMDF) solar thermal concepts which have been studied and developed in the DOE solar thermal program. Following the completion of earlier systems comparison studies in the late 1970's there have been a number of years of progress in solar thermal technology. This progress includes developing new solar components, improving component and system design details, constructing working systems, and collecting operating data on the systems. This study povides an update of the expected performance and cost of the major components, and an overall system energy cost for the FMDDF concepts evaluated. The projections in this study are for the late 1990's and are based on the potential capabilities that might be achieved with further technology development.

The syntheses of trans-(RuLBr/sub 2/)ClO/sub 4/ (L = (TMEA)/sub 2/ (TMEA = N,N,N',N'-tetramethyl-1,2-ethanediamine), 14-TMC (1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane), and 15-TMC), trans-(Ru(TMEA)/sub 2/(NCS)/sub 2/)NCS, and trans-(Ru(14-TMC)(CH/sub 3/CN)/sub 2/)(ClO/sub 4/)/sub 2/ are also described. The electrochemistry of trans-(RuLX/sub 2/)/sup +/ (L = (TMEA)/sub 2/, 14-TMC, 15-TMC, and 16-TMC; X = Cl, Br, and NCO) in acetonitrile were examined. Controlled-potential electrolyses of trans-(RuLX/sub 2/)/sup +/ at 1.30 V vs. the ferrocene couple generated some novel trans-(Ru/sup IV/LX/sub 2/)/sup 2 +/ complexes. The ligand-to-metal charge-transfer transitions in the UV-vis spectra of trans-(Ru/sup IV/(TMEA)/sub 2/X/sub 2/)/sup 2 +/ have been identified at 410 (X = Cl) and 570 nm (X = Br), which are considerably red-shifted with respect to their Ru(III) counterparts.

  7. Bowl breakout: Escaping the positive region when searching for saddle points

    We present a scheme improving the minimum-mode following method for finding first order saddle points by confining the displacements of atoms to the subset of those subject to the largest force. By doing so it is ensured that the displacement remains of a local character within regions where all eigenvalues of the Hessian matrix are positive. However, as soon as a region is entered where an eigenvalue turns negative all atoms are released to maintain the ability of determining concerted moves. Applying the proposed scheme reduces the required number of force calls for the determination of connected saddle points by a factor two or more compared to a free search. Furthermore, a wider distribution of the relevant low barrier saddle points is obtained. Finally, the dependency on the initial distortion and the applied maximal step size is reduced making minimum-mode guided searches both more robust and applicable.

  8. Are we living in a bowl of noodle soup?-origin of light and electron

    International Nuclear Information System (INIS)

    The origin of light and electron is a very fundamental issue in physics, and the activities for searching the answers have spanned almost in the whole history of physics. Starting from the corpuscular theory of light, the author explains why the wave theory can be successfully used to understand the light phenomena of refraction and interference. On the basis of the transverse property of light, the author further discusses the possibility of existence of a special medium, whose vibration corresponds to the light wave. After establishing the relationship of electricity and magnetic field, Maxwell pointed out that light is a kind of electromagnetic wave. According to the emergent principle of condensed matter physics, the author illustrated that it is the vibrations of the string density wave in a string-net liquid that correspond to the electromagnetic wave, and it is the ends of strings that correspond to electrons. A unified theory can be developed for the origin of light and electron. (author)

    Full Text Available The study was carried out in the Upper East Region of Ghana, Bongo District, to assess the driving causes and effects soil erosion in the District and the Region at large. While soil erosion is widely recognized as reducing environmental resource capacity to provide for the populations, few studies have explicitly measured its effects on the rural farmer and the apparent root causes of erosion in the region. Upper East Region is particularly vulnerable to the effects of soil erosion with one of the highest rates of soil erosion in Ghana. Some observed indicators of soil erosion-land degradation include sealed and compacted top soils, stones, gravel, concretions and iron pan. The major human activities that affect the physical environment are farming and domestic energy production. Associated practices such as land clearing for farming, total crop harvesting, burning of organic material during land preparation and inadequate manure application aggravate the degradation problem. These activities destroy the soil’s physical and chemical properties, thus, resulting in nutrient–depleted soils. A major effect is a progressive decline in crop yields as confirmed by 94% of 120 respondents. For soil rehabilitation to be effective there is the need for provision for soil surveys, research on soil physical characteristics affecting erosion, fertility investigations and the working out of new agricultural systems.

    2016-02-01

    Contact exposure is expected to occur in conventional lithography, and can be a source of process deviations (such as shrinking and distortion of templates) during reactive ion etching and inductively coupled plasma etching, as these deviations are induced by ion bombardment. This typically results in undesired sidewall effects, such as lower sidewall angles. Here we report a novel hanging bowlshaped lithography mask that can effectively minimize sidewall effects in lithography applications. As a test case, standard silicon carbide pillars with vertical sidewalls are fabricated using this mask. The mask could be used for fabrication of high-aspect-ratio structures with ultra-violet lithography.

    Muslim, Mohammad; Romshoo, Shakil Ahmad; Rather, A Q

    2015-06-01

    The Kashmir Himalayan region of India is expected to be highly prone to the change in agricultural land use because of its geo-ecological fragility, strategic location vis-à-vis the Himalayan landscape, its trans-boundary river basins, and inherent socio-economic instabilities. Food security and sustainability of the region are thus greatly challenged by these impacts. The effect of future climate change, increased competition for land and water, labor from non-agricultural sectors, and increasing population adds to this complex problem. In current study, paddy rice yield at regional level was estimated using GIS-based environment policy integrated climate (GEPIC) model. The general approach of current study involved combining regional level crop database, regional soil data base, farm management data, and climatic data outputs with GEPIC model. The simulated yield showed that estimated production to be 4305.55 kg/ha (43.05 q h(-1)). The crop varieties like Jhelum, K-39, Chenab, China 1039, China-1007, and Shalimar rice-1 grown in plains recorded average yield of 4783.3 kg/ha (47.83 q ha(-1)). Meanwhile, high altitude areas with varieties like Kohsaar, K-78 (Barkat), and K-332 recorded yield of 4102.2 kg/ha (41.02 q ha(-1)). The observed and simulated yield showed a good match with R (2) = 0.95, RMSE = 132.24 kg/ha, respectively. PMID:25937498

    In this brief letter the arguments of Sherouse in 2002, that the delivery of intensity-modulated radiation therapy (IMRT) does not necessarily require a multileaf collimator (MLC), are extended with specific reference to the possibility to use the jaws-only (JO) of an accelerator or some moving mask. With reference to the work in the last decade to develop JO IMRT the argument is made that it is not just the limitations of JO that are precluding its commercial development but also the commercial/business and reimbursement situations. A new moving-mask-IMRT technique that has high monitor-unit (MU) efficiency, but low MU per component, is illustrated. The letter is intended to stimulate debate and is not a criticism by the author of current MLC-based IMRT. PMID:21292523

    2015-09-01

    Situated in China's market transition, this study examines the relationship between economic sector and a worker's happiness in post-reform urban China. Using datasets from the Chinese General Social Surveys 2003, 2006 and 2008, we find that workers in the state sector enjoy a subjective premium in well-being - reporting significantly higher levels of happiness than their counterparts in the private sector. We also find that during a period when a large wave of workers moved from the state sector to the private sector, those remaining in the state sector reported being significantly happier than did former state sector workers who had moved, whether the move was voluntary or involuntary. We attribute the higher level of reported happiness in the state sector than in the private sector to the disparity by sector in the provision of social welfare benefits. Those who made voluntary state-to-private moves experienced a trade-off in enjoying higher payoffs while losing job security, whereas involuntary mobiles experienced downward mobility and suffered a long-term psychological penalty.

The results were contrasted with prussian blue promoted hydrolysis of 4-nitrophenyl phosphate. The tetraamineCobalt(III complexes accelerated the hydrolytic reaction to varying degrees with the following reactivity order. [(tn2Co(OH22]3+ < [(trpnCo(OH22]3+ < [(tme2Co(OH22]3+ [ tn = trimethylenediamine; tme = 1,1,2,2-tetramethyl-1,2-diaminoethane; trpn = tris(3- aminopropylamine].These observations are attributed to the active aquo-hydroxo forms of the tetraamineCobalt(III complexes. The hydrolysis rate for prussian blue promoted hydrolysis was comparable to that obtained for [(tme2Co(OH22]3+. The mixed valence bimetallic centers of prussian blue aid in substrate binding and organizing the nitrophenyl phosphate for effective intramolecular nucleophilic attack by coordinated hydroxide or water.

    Andrea S Fogarty

    Full Text Available INTRODUCTION: Policies affecting alcohol's price and promotion are effective measures to reduce harms. Yet policies targeting populations are unpopular with the public, whose views can be influenced by news framings of policy narratives. In Australia, alcohol taxation receives high news coverage, while advertising restrictions have not until recently, and narratives are highly contested for each. However, research specifically examining how audiences respond to such news stories is scant. We sought to explore audience understanding of news reports about two alcohol policy proposals. METHOD: From June to August 2012, 46 participants were recruited for 8 focus groups in age-brackets of young people aged 18-25 years, parents of young people, and adults aged 25 or older. Groups were split by education. Participants were asked their prior knowledge of alcohol policies, before watching and discussing four news stories about alcohol taxation and advertising. RESULTS: Participants were clear that alcohol poses problems, yet thought policy solutions were ineffective in a drinking culture they viewed as unamenable to change and unaffected by alcohol's price or promotion. Without knowledge of its actual effect on consumption, they cited the 2008 alcopops tax as a policy failure, blaming cheaper substitution. Participants had low knowledge of advertising restrictions, yet were concerned about underage exposure. They offered conditional support for restrictions, while doubting its effectiveness. There was marked distrust of statistics and news actors in broadcasts, yet discussions matched previous research findings. CONCLUSIONS: News coverage has resulted in strong audience understanding of alcohol related problems but framed solutions have not always provided clear messages, despite audience support for policies. Future advocacy will need to continue recent moves to address the links between alcohol's price and promotion with the drinking culture, as well as facilitate understandings of how this culture is amenable to change through the use of evidence-based policies.

    Gender inequality in sport has received significant attention from sports development initiatives and sociologists of sport. Gender inequality describes the structuring of aspects of society that favours one gender over another. Feminist academic literature is heavily focused around how the inequality is perpetuated in society (Hargreaves, J. (2000) Heroines of Sport: ‘The politics of difference and identity’. London: Routledge.). The prevalence of gender inequality is reflected in women’s pa...

    In order to identify new compounds to treat Chagas disease during the acute phase with higher activity and lower toxicity than the reference drug benznidazole (Bz), a series of tetraamine-based compounds was prepared and their trypanocidal effects against Trypanosoma cruzi were evaluated by light microscopy through the determination of IC50 values. Cytotoxicity was determined by flow cytometry assays against Vero cells. In vivo assays were performed in BALB/c mice, in which the parasitemia levels were quantified by fresh blood examination; the assignment of a cure was determined by PCR and reactivation of blood parasitemia levels after immunosuppression. The mechanism of action was elucidated at metabolic and ultra-structural levels by (1)H NMR and TEM studies. Finally, as tetraamines are potentially capable of casuing oxidative damage in the parasites, the study was completed by assessing their activity as potential iron superoxide dismutase (Fe-SOD) and trypanothione reductase (TR) inhibitors. High-selectivity indexes observed in vitro were the basis of promoting three of the tested compounds to in vivo assays. The tests on the murine model for the acute phase of Chagas disease showed better parasitemia inhibition values than those found for Bz. Tetraamines 2 and 3 induced a remarkable decrease in the reactivation of parasitemia after immunosuppression and curative rates of 33 and 50%, respectively. Tetraamine 3 turned out to be a great inhibitor of Fe-SOD and TR. The high anti-parasitic activity and low toxicity render these tetraamines appropriate molecules for the development of an affordable anti-Chagas agent. PMID:26874306

    Full Text Available The title salt, C16H24N42+·2C7H7O3S−, crystallizes with the dication situated on an inversion center and the anion in a general position. The cation contains two ammonium and two free amine groups, and the observed conformation for the chain linking the benzene rings is different from that found in the free tetraamine and in the fully protonated tetraamine. All amine and ammonium H atoms of the cation form hydrogen bonds with eight symmetry-related anions, using the sulfonate O atoms as acceptors. This arrangement for the ions precludes any π–π contacts between benzene rings in the crystal.

  7. Engine structure modifications effect on the flow behavior, combustion, and performance characteristics of DI diesel engine

    International Nuclear Information System (INIS)

    Highlights: • Engine geometrical configuration was modified based on bowl radius and displacement. • The best engine performance indices associated with D3 and R1 structures. • Increasing the bowl radius and outward bowl displacement increases ignition delay. • The best configuration for uniform air/fuel mixture, TKE, and temperature is found. - Abstract: The simulation was carried out based on 1.8 L Ford diesel engine and the geometrical modification in structure of piston were considered in terms of bowl movement and the bowl size in four equal increments. Two major conflicting parameters in combustion and engine efficiency were taken into account and visualized in contour plots as the bowl geometry was varied: (1) the air/fuel mixing process demonstrated by Homogeneity Factor and equivalence ratio, (2) combustion initiation and work delivery by heat release rate, pressure curves, and indicated thermal efficiency. A new version of Coherent Flame Model’s sub-model (ECFM-3Z) was adopted during the calculations to shed light into the combustion chemistry and reaction rate in detail. It was found that the bowl displacement toward the cylinder wall, increases the mixture uniformity (higher HF) thus higher pressure and heat release rate peak were obtained with the penalty of combustion delay which substantially reduces the effective in-cylinder pressure. Furthermore, it was demonstrated that smaller bowl size induces better squish and vortex formation in the chamber, although lesser spray penetration and flame quenching owing to the spray-wall impingement reduces ignition delay

  9. Radionuclide study of gastric emptying in anorexia nervosa patients

    International Nuclear Information System (INIS)

    To evaluate gastric emptying, 20 patients with anorexia nervosa were given 150 μCi of Tc-99m triethylene tetraamine polystyrene resin in cereal and were imaged in the supine position. Data were accumulated at 5-minute intervals to determine the gastric emptying time (GET). The GET results were divided into three categories: prolonged (10 patients); rapid (eight); and normal (two). Although all patients had symptoms of gastric dysfunction, only 50% had prolonged GET. This study allows the objective documentation of gastric emptying and the separation of patients with rapid or normal GET from those with prolonged GET, who might benefit from metoclopramide

    The purpose of the invention is to increase the reliability of plugging and to prevent the formation of agressive and corrosive byproducts. The cited purpose is achieved by controlling overflows of hydrogen sulfide bearing stratum waters in to the casing annulus of a well through plugging the pore space of the appearing stratum with the sediment which is formed with interaction between the hydrogen sulfide and the reagent pumped into the stratum. An aqueous solution of tetraamine copper (II) hydroxide is used as the reagent pumped into the stratum. The reagent is used in the form of a 0.1 to 0.5 percent aqueous solution.

    A hydrogen-absorbing composition and method for making such a composition. The composition comprises a metal hydride, preferably palladium, deposited onto a porous substrate such as kieselguhr, for use in hydrogen-absorbing processes. The composition is made by immersing a substrate in a concentrated solution containing palladium, such as tetra-amine palladium nitrate. Palladium from the solution is deposited onto the porous substrate, which is preferably in the form of kieselguhr particles. The substrate is then removed from the solution, calcined, and heat treated. This process is repeated until the desired amount of palladium has been deposited onto the substrate.

    1990-09-01

    The synthesis of two new N- and C-functionalized tetraazamacrocyclic ligands intended to be covalently linked to biomolecules like monoclonal antibodies and to bind the gamma-emitting isotope indium-111 in a thermodynamically and/or kinetically inert way is described. 12-(p-Nitrobenzyl)-1,4,7,10-tetraazacyclotridecane-1,4,7,10-tetraa cetic acid (L1) was synthesized by means of bimolecular cyclization with the appropriate malonic acid diethyl ester and triethylenetetraamine, followed by reduction with diborane and alkylation of the cyclic tetraamine with bromoacetic acid. The corresponding triscarboxymethylated ligand L2 was made by statistical alkylation of the tetraamine. Both ligands fulfill the criteria for antibody labeling using the bifunctional chelate approach, namely fast chelate formation, high radiochemical yield, and high stability under physiological conditions. Surprisingly the heptadentate ligand L2 confers higher stability to In3+ and exhibits faster complex formation than octadentate L1. 13C NMR spectra in solution indicate that the difference in stability is not due to incomplete coordination of all four carboxylate groups in In-L1.

    2016-01-01

    Availability of mass flowering plants in landscapes dominated by agriculture can have a strong positive impact on the density of generalist, native pollinators. Row-crop production in Iowa accounts for 75% of the arable acres, with corn, Zea mays, representing the majority of hectares planted. To date, there has been no description of the insect pollinator community found within Iowa cornfields. We report a field study to determine the optimal sampling methodology to characterize the community of insect pollinators within cornfields. During 2012 and 2013, 3,616 insect pollinators representing 51 species were captured using bee bowls, and 945 individuals representing 10 species were captured using sticky cards. We examined the effects of trap type, height, and bowl color on the described community. Bee bowls captured a more abundant and species rich community than sticky cards with all species captured on sticky cards also present in bee bowls. Traps deployed at the height of the tassels describe a more abundant and species rich community of pollinators than traps at ear height (2x as many individuals) or ground height (4x as many individuals). Blue bowls captured more bees than white (2.75x as many individuals) or yellow bowls (3.5x as many individuals); and yellow bowls captured more flies than white (2x as many individuals) or blue (2.3x as many individuals). To provide the most complete description of the community of insect pollinators using cornfields as a resource, we suggest sampling-using bee bowls at the height of the tassels using all three bee bowl colors.

The results indicate that computational fluid dynamics could help screen preliminary centrifuge bowl designs thus reducing the number of initial experimental tests required when developing new centrifuge bowls. Though the focus of this work is on washing shed blood the methods developed here are applicable to the design of centrifuge bowls for other blood processing applications. PMID:15133962

    2004-01-01

    In the model of Chain Inflation, a sequential chain of coupled scalar fields drives inflation. We consider a multidimensional potential with a large number of bowls, or local minima, separated by energy barriers: inflation takes place as the system tunnels from the highest energy bowl to another bowl of lower energy, and so on until it reaches the zero energy ground state. Such a scenario can be motivated by the many vacua in the stringy landscape, and our model can apply to other multidimens...

    In order to reduce defects and improve casting quality, ProCAST software is performed to study the solidification process of discharge bowl. Simulated results of original casting process show that the hot tearing is serious at the intersection of blades and outer or inner rings. The shrinkage porosity appears at the bottom of discharge bowl and the transition area of wall thickness. Based on the formation mechanisms of the defects, the structure of chills attached on the outer surface of discharge bowl casting is optimized. The thickness of chills ranges from 25mm to 35mm. The positions of chills corresponded to the outer surface of the T-shaped parts. Compared to the original casting design (without chills), the hot tearing and shrinkage porosity of the discharge bowl are greatly improved with addition of chills.

    2012-06-28

    Ruthenium complexes including nitrosyl or nitrite complexes are particularly interesting because they can not only scavenge but also release nitric oxide in a controlled manner, regulating the NO-level in vivo. The judicious choice of ligands attached to the [RuNO] core has been shown to be a suitable strategy to modulate NO reactivity in these complexes. In order to understand the influence of different equatorial ligands on the electronic structure of the Ru-NO chemical bonding, and thus on the reactivity of the coordinated NO, we propose an investigation of the nature of the Ru-NO chemical bond by means of energy decomposition analysis (EDA), considering tetraamine and tetraazamacrocycles as equatorial ligands, prior to and after the reduction of the {RuNO}(6) moiety by one electron. This investigation provides a deep insight into the Ru-NO bonding situation, which is fundamental in designing new ruthenium nitrosyl complexes with potential biological applications. PMID:22580477

    An investigation was made into the characteristics, treatment, and possible uses of the coking plant wastewater. Included were data on the volumes of wastewater from various processes in the coking plants. Also included were data on the contaminants of the various components and the total wastewater. Among other suggestions, it was recommended that all contaminated waters be kept from the storm sewer system. It was concluded that an increase in the coefficients of evaporation and treatment of the water with copper tetraamine sulfate would permit a decrease in the demand for fresh water and a decrease in the discharge from the plant. Also, it was concluded that a major obstacle in the use of the total effluent was mineralization. Seven tables of data were included in the work.

In the cation, both benzene rings are connected by an all-trans chain, and the rings are almost parallel, with an angle between the mean planes of 8.34 (12°. The benzene rings are arranged in such a way that the NH3+ substituents are oriented cis with respect to the central chain. This arrangement is a consequence of multiple N—H...Cl hydrogen bonds, involving all N—H groups in the cation and the four independent Cl− anions. These contacts have strengths ranging from weak to strong (based on H...Cl separations, and generate a complex three-dimensional crystal structure with no preferential crystallographic orientation for the contacts.

    This study reports the synthesis of palladium and rhodium metal nanoparticles supported on montmorillonite (MMT) and partially organically modified MMT (POMM) using tetraamine palladium and hexaamine rhodium complex as precursor for palladium and rhodium respectively. The synthesized nanoparticles were characterized by powder X-ray diffraction PXRD and TEM. The PXRD study shows characteristic crystallographic planes for Pd and Rh metal and confirm the formation of metal nanoparticles in MMT and POMM. The TEM images reveal the effect of organic modification of MMT on decreasing particle size of Pd and Rh metal. The Pd and Rh metal nanoparticles are agglomerated in pristine MMT while nanoparticles are well dispersed in POMM. ICP-AES analysis was carried out to estimate quantitative amount of Pd and Rh metal in MMT and POMM.

    Cyclic tetradentate amine seems suitable for systematic control of redox potential of complexes performed by changing central metal ion or amine electron donor. Therefore, electrocatalytic reduction of alkyl halides was studied in acetonitrile to pursue the electrocatalytic effect of the Ni and Co complexes. Cyclic voltametric and coulometric measurements indicated that the Ni(I) complexes generated electrochemically reacted with benzil, butyl and hexyl bromides and reverted to the corresponding Ni(II) complexes. Of benzyl bromide and unsaturated alkyl, for example with the former, current efficiency of bibenzil was the largest for NiL{sub 4}(where L means tetraamine), and for the complexes where the half wave potential is lower than that, the toluene production was remarkable. This result was probably due to direct electroreduction of benzyl radical in the negative potential region. 17 refs., 6 figs., 3 tabs.

  3. One-Step Facile Synthesis of a Simple Hole Transport Material for Efficient Perovskite Solar Cells

    KAUST Repository

    Chen, Hu

    2016-04-04

    A hole transporting material was designed for use in perovskite solar cells, with a facile one-step synthesis from inexpensive, com-mercially available reagents. The molecule comprises a central fluorinated phenyl core with pendant aryl amines, namely, 3,6-difluoro-N1,N1,N2,N2,N4,N4,N5,N5-octakis(4-methoxyphenyl)benzene-1,2,4,5-tetraamine (DFTAB). A power conversion efficiency of up to 10.4% was achieved in a mesoporous perovskite device architecture. The merits of a simple and potentially low cost syn-thetic route as well as promising performance in perovskite devices, encourages further development of this materials class as new low-cost hole transporting materials for the scale up of perovskite solar cells.

    The synthesis of a new series of strati-bisporphyrins (sbPs) is reported. The synthesis via the preparation of the first amide-linked sbP, tetra-meso-(m,m' (N-benzyl benzamide)) strati-bisporphyrin, III. This highly symmetric and well defined staked porphyrin dimer of two meso-substituted tetra phenyl porphyrins joined at the meta positions of all eight phenyl groups by four methyl formamide linkages, -CH/sub 2/NHCO-. This sbP is being prepared by the de-novo coupling procedure where a second porphyrin ring is constructed upon an initial porphyrin ring by way of the internal condensation of a porphyrin tetraaldehyde with four pyrrole molecules. This is the same general scheme which was successfully used in the synthesis of the first sbP system which had ester linkages. The necessary porphyrin tetraaldehyde for this new amide-linked dimer has already been synthesized. The porphyrin, tetraaldehyde, T-meso (m-N-benzyl(m'-formyl)benzamide) porphyrin, II, was prepared by the acylation of a porphyrin tetraamine with m-chlorocarbonyl benzaldehyde. The porphyrin tetraamine, tetra-meso-(m-aminomethyl-phenyl porphyrin, I, was prepared by the condensation of the shiff-base polymer of m-amino-methyl benzaldehyde with pyrrole in the usual way. The most effective synthetic scheme for the sbP III begins with the preparation of the essential benzaldehydes 5 and 9 by the bromination of commercially available toluene derivatives. The fluorescence and other photophysical properties of these molecules will be studied as purified samples are prepared. 3 figures. (DMC)

  5. Baclofen reduces fat intake under binge-type conditions.

    The GABA-B agonist baclofen reduces drug self-administration in rats and has shown promise clinically in the treatment of substance abuse. Baclofen generally does not reduce food intake in non-binge feeding protocols. In this study, baclofen was tested in a fat-binge protocol. Thirty male rats were divided into three groups (B: binge; FM: fat-matched; C: chow). B received a bowl of vegetable shortening for 2 h on Monday, Wednesday, and Friday (MWF) and continuous access to powdered chow (regular chow) in all phases. FM had continuous access to a regular chow+shortening mixture (FM chow) that provided the same proportion of shortening and regular chow that the B rats consumed in all phases. In addition, FM had the following: phase 1: no separate bowl of shortening; phase 2: 2-h MWF access to a separate bowl of shortening; phase 3, daily 2-h access to a separate bowl of shortening; C rats had continuous access to the regular chow in all phases. In addition, C had the following: phase 1: no separate bowl of shortening; phase 2: 2-h MWF access to a separate bowl of shortening; in phase 3, daily 2-h access to a separate bowl of shortening. Baclofen (1.0, 1.8 mg/kg, i.p.) reduced shortening intake regardless of access condition. Baclofen had no effect on, or stimulated, FM and regular chow intake. These results demonstrate that baclofen can reduce fat intake in rats under binge-type conditions. Furthermore, these results indicate that bingeing, as modeled in our protocol, is different from other forms of food intake and may share similarities with substance abuse. PMID:16140347

  6. Energy efficient piston configuration for effective air motion – A CFD study

    International Nuclear Information System (INIS)

    Highlights: ► All piston crown show similar flow pattern for experimental and simulated studies. ► Piston position plays a predominant role in the air pattern inside the cylinder. ► The flat bowl piston shows higher TKE compared to all other piston crown shape. ► The turbulence intensity and length scale are higher for flat bowl piston. ► The quantitative error between the CFD and PIV analysis is about 5%. -- Abstract: Air motion inside the cylinder is very important from the point of view of energy efficiency. In this direction, piston configuration plays a very crucial role. This study is concerned with the CFD analysis of in-cylinder air motion coupled with the comparison of predicted results with the experimental results available in the literature. Four configurations viz., flat, inclined, centre bowl and inclined offset bowl pistons have been studied. For numerical analysis STAR-CD CFD software has been used. Experimental results available in the literature for comparison are obtained by PIV measurements. From this study, it is concluded that a centre bowl on flat piston is found to be the best from the point of view of tumble ratio, turbulent kinetic energy, turbulent intensity and turbulent length scale which play very important role in imparting proper air motion, there by increasing the energy efficiency of the engine.

    The electronic structure of the C20 cluster in monocyclic ring, bowl and fullerene isomers has been calculated using the tight-binding scheme developed by Harrison, starting in particular from the sp2.803-hybrids for the fullerene structure. The study of energetics predicts the fullerene to be the ground state with the bowl and ring lying over 1.32 and 3.35 eV higher in energy. The total energies will be lowered by Peierls or Jahn-Teller distortion, but the energetic ordering remains unchanged. It is also shown that the range of valence electron, the level difference between the highest occupied molecular orbital and the lowest unoccupied molecular orbital as well as the σ - π gap, which are less sensitive to the exact geometry, vary in the ring, bowl and fullerene sequence.

  8. History and development of whole body counting in Brazil

    International Nuclear Information System (INIS)

    The first whole body counter (WBC) built in Brazil used sugar as shielding material, and for this reason became internationally known as the open-quotes Sugar Bowl.close quotes The main purpose of building that first WBC was to detect natural gamma emitters other than 40K in the inhabitants of Guarapari, then a small fishing village with a population not greater than 6,000 people, suspected of having long-lived contamination with natural radionuclides of the 232Th and 238U series. However, the Sugar Bowl was also used to whole body count the workers of a gas mantle factory. This paper reviews the history behind the construction and uses of the Sugar Bowl, as well as presents a brief view of the basic characteristics of the subsequent WBCs built in Brazil. A total of 12 WBCs have been in existence in this country until today

    1982-02-01

    This report presents the preliminary design and the construction cost for a 5 MWe Solar Hybrid Electric Energy Plant (SHEEP) to be built at Crosbyton, Texas. The plant has been designed to serve as a small size, commercially operable power plant which fully demonstrates the function, performance, and cost of this solar technology and integrated steam management concept. Good lifetime performance at minimum cost were the critical design objectives. The major solar components of this plant are ten 203 foot diameter stationary tilted quartersphere solar bowls. Each with a slender 58 foot solar receiver which tracks the solar focus produced by the bowl. At peak insolation the ten bowls will produce sufficient steam to generate 5 MWe. This plant has only a few minutes of thermal storage capability. The plant has a fossil boiler (oil or gas fired) which is integrated into the solar-turbine steam loop to provide supplemental steam for electric generation at night or during periods of low insolation.

    2015-01-01

    Full Text Available The pet food industry continues to grow steadily as a result of new innovative products. Quality control and product development tests for pet foods are typically conducted through palatability testing with dogs and cats. Palatability is the measure of intake of a food that indicates acceptance or the measure of preference of one food over another. Pet food palatability is most commonly measured using a single-bowl or a two-bowl assay. While these tests answer some questions about the animals’ perception of the food, there are many limitations as well. This review addresses some of these limitations and indicates opportunities for future research.

  3. NTS1-R-targeted diagnostic imaging of malignant tumors with 99mTc labeled neurotensin analogues

    International Nuclear Information System (INIS)

    Full text: Recent studies, based on receptor radio autoradiography methods in human biopsy specimens, have demonstrated the expression of neurotensin receptors of subtype 1 (NTSI-R) at a high density in primary human cancers, such as in ductal exocrine pancreatic carcinoma, Ewing's sarcoma and meningioma. This finding provides the molecular basis for the scintigraphic detection of NTS1-R-positive tumors in patients using radiolabeled NT analogues in combination with SPECT. We synthesized two novel NT analogues based on the NT (8-13) peptide sequence - essential for interaction with the NTS1-R - and modified at the N-terminal by a covalently attached open chain tetraamine chelator for stable binding of the radionuclide. In this work, a comparative study of the new compounds in cells and animal models is presented and their suitability in the NTS1-R- targeted diagnostic imaging of malignant tumors is discussed. In particular, the tetra-amine functional analogues NT1: [N4- (a) Ala0, Dab9] NT (8-13) and NT2: [N4- (a) Ala0, Dab9, Tle12] NT (8-13) were synthesized by SPPS techniques applying Fmoc/Boc protection strategies. The ES-MS spectra of the chromatographically purified products were consistent with the expected formulae. Incorporation of the radiometal (99mTc) by the open chain tetraamine framework proceeded different at room temperature in alkaline aqueous medium using SnCl2 as reducing agent in the presence of citrate. Under the above mild conditions labelling was nearly quantitative leading to single radiopeptide species of high specific activity. During competition binding assays in human colon adenocarcinoma WiDr cell membranes, using [125I-Tyr3] NT as the radioligand, both peptide conjugates demonstrated high affinity binding to the NTS1-R with IC50s 30 and 80 pM, respectively (IC50 for native NT= 0.20 nM). Both radiopeptides showed a rapid and NTS1-R-mediated migration into the intracellular compartment of the same cells reaching a 95% internalization

    Somatostatin receptor (SSTR) scintigraphy with indium-111 DTPA-octreotide has become a routine diagnostic procedure in oncology. However, it suffers some drawbacks concerning the limited availability, suboptimal imaging properties and elevated radiation burden of {sup 111}In. We have recently been involved in the development of a new tetraamine-functionalised [Tyr{sup 3}]octreotate derivative (Demotate 1) that can be easily labelled with technetium-99m at high specific activities. {sup 99m}Tc-Demotate 1 showed promising properties in preclinical studies. In this study we report on the first experience with {sup 99m}Tc-Demotate 1 in patients. Six patients (mean age 56 years) with carcinoid tumours (n=2) or endocrine pancreatic tumours (n=4) with previously positive SSTR scintigraphy were enrolled in the study. Patients were injected with 500-600 MBq {sup 99m}Tc-Demotate 1. Clinical and laboratory parameters were controlled up to 3 months p.i. Blood samples were taken at various time points up to 24 h p.i., and urine was collected up to 24 h. Whole-body images were acquired at 15-30 min, 1-2 h, 4 h and 24 h p.i. with additional single-photon emission tomography imaging at 1-4 h. Blood excretion was very rapid, with <2%ID in plasma after 1 h, and urinary excretion <20% ID after 6 h. Two patients complained of mild gastrointestinal problems and paraesthesia, but no other adverse reactions were observed. SSTR-positive tumours were rapidly visualised as early as 15 min p.i., with maximum tumour uptake (up to 19% ID) and tumour/organ ratios as early as 1 h p.i. Organs of predominant physiological uptake were the spleen and the kidneys, with no intestinal excretion detectable up to 24 h. {sup 99m}Tc-Demotate 1 detected 11 lesions while In-Oct detected ten; differences in uptake behaviour were observed in three patients. This study shows for the first time that peptides derivatised with a tetraamine ligand for labelling with {sup 99m}Tc show suitable properties for receptor

  5. TMI Unit 2 post-accident defueling. Experience and lessons learned

    International Nuclear Information System (INIS)

    The 1979 accident at Three Mile Island Unit 2 left a bowl shaped, hardened mass of core components and fuel in the upper third of the fuel assembly region. The area of core damage was defined by the steam blanketing that had pushed down from the upper head. As the liquefied core mass formed, it began to run down the intact fuel rods and solidified when it encountered liquid coolant. The liquid core material flowed down into the undamaged fuel rods a short distance prior to solidifying, defining the bowl thickness and anchoring the bowl to the remaining, intact fuel rods. After the bowl formed - creating a container for the liquefied fuel - the remaining, melted core material collected in the bowl. The bowl filled and eventually melted through a core former plate, spilling down to the vessel lower head. As cooling was restored, the liquefied bowl solidified forming a monolith. Initial defueling attempts were blocked by the presence of this monolithic mass. A computerized well drilling machine was used to capture 'as found' vertical samples of the core and then break up the monolithic mass. This process left a rubble bed of fuel, fuel rods, and other core fragments. A significant challenge was imposed by the fuel fines that were created by the accident and by the breakup of the monolith. The fines eliminated visibility and greatly retarded effective cleanup work in the core until engineering solutions were applied. Unknown fissile material configuration, high levels of radiation from the deranged core, and the need for human access to complete the work also required extensive engineering to resolve. A workforce, skilled in the use of 40 foot (12m) long, camera guided, under water tools was non-existent at the beginning of the cleanup process, but was rapidly developed out of necessity. At one point in the cleanup process, high levels of bacteria present in the coolant threatened to stop the project. Many issues surfaced during the cleanup that required specialty

  7. Rainfall variability and predictability issues for North America

    Science.gov (United States)

    Hunt, B. G.

    2016-04-01

    A multi-millennial simulation with a coupled global climatic model has been used to investigate extreme rainfall events, mainly droughts, over North America. A rainfall index, based on the US Dust Bowl region, was used to generate a time series from which the extreme events could be identified. A very wide range of drought and pluvial multiyear sequences was obtained, all attributable to internal climatic variability. This time series reproduced the basic characteristics of the corresponding observed time series. Composites of years with negative rainfall anomalies over North America from the simulation replicated the observed rainfall composite for the Dust Bowl era, both in spatial character and intensity. Examination of individual years of a simulated composite revealed not only a wide range of rainfall anomaly patterns, dominated by drought conditions, but also ENSO distributions that included El Niño events as well as the expected La Niña events. Composites for pluvial conditions over North America were associated with composited El Niño events, as expected. Correlation of the simulated Dust Bowl rainfall with global surface temperatures identified a principal connection with the ENSO region. No systematic relationship was obtained in the simulation between the Atlantic multidecadal oscillation and Dust Bowl region rainfall, with the simulated oscillation having a much more variable periodicity than that found in the limited observations. However, a marked connection was found for SST anomalies adjacent to the northeast coast of North America, but this appears to be forced by ENSO events. A scatter diagram of NINO3.4 SST anomalies with the Dust Bowl region rainfall anomalies, for observations and the simulation, revealed inconsistencies between the occurrence of an ENSO event and the "expected" rainfall anomaly. This, and other analysis, resulted in the conclusion that annual or longer term rainfall predictions over North America, with any systematic

  8. Characterization of Urea Versus hmta in the Preparation of Zinc Oxide NANOSTRUCTURES by Catalytic Immersion Method Grown on Gold-seeded Silicon Substrate

    International Nuclear Information System (INIS)

    Zinc oxide (ZnO) nano structured prepared by immersed method were successfully grown on gold-seeded silicon substrate using Zinc nitrate hexahydrate (Zn(NO3)2.6H2O) as a precursor was stabilized by a non-toxic urea (CH4N2O) in a ratio of 1:2 and 1:1 ratio of hexamethylene tetraamine (HMTA). The effect of changing the stabilizer of ZnO solution on the crystal structure, morphology and photoluminescence properties of the resultant ZnO is investigated. X-ray diffraction of the synthesized ZnO shows hexagonal zincite structure. The morphology of the ZnO was characterizing using Field Emission Scanning Electron Microscope (FESEM). The growth of ZnO using urea as stabilizer shows the clusters of ZnO nano flower with serrated broad petals and sharp tips of approximately 25 nm were interestingly formed. ZnO in HMTA showed growth of nano rods. The structures has high surface area, is a potential metal oxide nano structures to be develop for optoelectronic devices and chemical sensors. The formation of ZnO nano structures is found to be significantly affected by the stabilizer. (author)

  9. Optimization of labeling and metabolite analysis of copper-64-labeled azamacrocyclic chelators by radio-LC-MS

    International Nuclear Information System (INIS)

    The cross-bridged tetraamine ligand 4,11-bis(carboxymethyl)-1,4,8,11-tetraazabicyclo[6.6.2]hexadecane (H2CB-TE2A) allows formation of a radio-copper complex with higher in vivo stability than that of the corresponding non-cross-bridged analog 1,4,8,11-tetraazacyclotetradecane-1,4,8,11-tetraacetic acid (TETA). The structure of the natCu(II) complex of CB-TE2A has been previously determined by X-ray crystallography; however, direct high-pressure liquid chromatography (HPLC) characterization of the corresponding 64Cu complex was inaccessible due to the inability to detect the complex by ultraviolet absorbance at the radiotracer level. A reverse-phase HPLC separation of a series of natCu(II)-tetraazamacrocyclic complexes, both traditional and cross-bridged, was developed and applied toward characterization and assessment of the purity of the corresponding no-carrier-added 64Cu-labeled complexes. Verification of the identity of copper-64-labeled compounds was also achieved by coupling this HPLC method with mass spectrometry. The radio-liquid chromatography/mass spectrometry methodology was further extended to study the in vivo metabolic fates of 64Cu-azamacrocyclic complexes

    Cyclam, ethylenediamine (EN) and a linear tetraamine (TA) form structurally similar complexes in high yields when pertechnetate is reduced with Sn(II) in aqueous solutions. Efficient labeling of these amine ligands is also accomplished by transfer of sup(99m)Tc from its complexes with diethylenetriaminepentaacetate (DTPA) and citrate. The labeling yields of cyclam, TA and EN using (sup(99m)Tc)DTPA are greater than 95% after standing for 30 min at room temperature in 0.03 M solutions of the amine ligands at pH above 11, but less than 10% at pH below 9. Yields of greater than 90% are obtained using (sup(99m)Tc)citrate under similar conditions at pH 7 or greater. Ethylenediamine-N,N'-diacetic acid (ENDA) also forms a complex with sup(99m)Tc that exhibits pH dependent stability characteristics that are the same as those of (sup(99m)Tc)EN. The labeling efficiency of ENDA with sup(99m)Tc as a function of pH is nearly identical to that of the other amine ligands.

    The rate of deuteration at malonate hydrogens has been measured for (Co(mal)(N)/sub 4/)/sup +/ and (Co(malH)-(NH/sub 3/)/sub 5/)/sup 2 +/ ions in aqueous solution over the pD range of 2 to 8, where mal =malonate dianion, malH=malonate monoanion, and (N)/sub 4/=(NH/sub 3/)/sub 4/, (ethylenediamine)/sub 2/, (1,3-propanediamine)/sub 2/, (1,10-phenanthroline)/sub 2/, or (2,2'-bipyridine)/sub 2/. For the tetraamine type complexes with a chelated malonate ligand, the deuteration process is acid-catalysed up to pD=about 4 and base-catalysed at higher pD values. This contrasts with the behavior of the unidentate malonate ligand, for which the deuteration is base-catalysed up to pD=3.5, whereupon the deprotonation of the carboxylate group takes place and the deuteration rate steps down to a constant, pH-independent value. The deuteration mechanisms are discussed.

    The cross-bridged tetraamine ligand 4,11-bis(carboxymethyl)-1,4,8,11-tetraazabicyclo[6.6.2]hexadecane (H{sub 2}CB-TE2A) allows formation of a radio-copper complex with higher in vivo stability than that of the corresponding non-cross-bridged analog 1,4,8,11-tetraazacyclotetradecane-1,4,8,11-tetraacetic acid (TETA). The structure of the {sup nat}Cu(II) complex of CB-TE2A has been previously determined by X-ray crystallography; however, direct high-pressure liquid chromatography (HPLC) characterization of the corresponding {sup 64}Cu complex was inaccessible due to the inability to detect the complex by ultraviolet absorbance at the radiotracer level. A reverse-phase HPLC separation of a series of {sup nat}Cu(II)-tetraazamacrocyclic complexes, both traditional and cross-bridged, was developed and applied toward characterization and assessment of the purity of the corresponding no-carrier-added {sup 64}Cu-labeled complexes. Verification of the identity of copper-64-labeled compounds was also achieved by coupling this HPLC method with mass spectrometry. The radio-liquid chromatography/mass spectrometry methodology was further extended to study the in vivo metabolic fates of {sup 64}Cu-azamacrocyclic complexes.0.

    In this research a theoretical study on the successive proton macroaffinities of a linear aliphatic tetraamine, spermine, via density functional theory (DFT) is carried out. DFT (B3LYP) calculations employing standard 6-31G{sup *} basis set are used to determine the gas phase protonation energies. We studied all possible microspecies for all L, HL{sup +}, H{sub 2}L{sup 2+}, H{sub 3}L{sup 3+} and H{sub 4}L{sup 4+} species that differ in the location of proton/charge and all possible conformers for all microspecies that differ in the number and/or the location of intramolecular hydrogen bonding. Then the most stable conformers as well as the most abundant conformers were determined in each case. Two different schemes were considered for full protonation steps of spermine according to latter conformers. Then the proton micro-, macro- and for both schemes were determined according to our published method.

    Fourteen ether-containing, aromatic dianhydrides have been synthesized from N-phenyl-3 or 4-nitrophthalimide and various bisphenols. The process involves nucleophilic displacement of activated nitro groups with bisphenolate ions. Ether-containing dianhydrides were indefinitely stable in the presence of atmospheric moisture. One-step, high temperature solution polymerization of the ether-containing dianhydrides with m-phenylene diamine, 4,4'-oxydianiline and 1, 3-bis(4-aminophenoxy)benzene afforded 42 polyetherimides. The polyetherimides were all soluble in m-cresol except two which were found to be crystalline. The glass transition temperatures of the polyetherimides ranged from 178 to 277 C. Soluble polybenzimidazopyrrolones containing ether groups were also prepared from the same ether-containing dianhydrides and aromatic tetraamines by one-step solution polymerization. Using low molecular weight polyetherimides, various thermoset resin systems were developed and tested as matrices for fiber-reinforced composites. The curing chemistry involving reaction of the phthalonitrile group and the o-diaminophenyl group was found to be generally applicable to crosslinking various aromatic polymers other than polyimides.

    The effect of various amino groups on gene vector is different. In order to combine their effect in one vector and finally promote the transfection efficiency, a biogenic tetra-amine spermine was introduced to modify the stearic acid-grafted chitosan oligosaccharide (CSOSA) polymer to build a new gene delivery system. The spermine linked CSOSA (SP-CSOSA) polymer consists two types of amino groups with 73.3%, 19.3% of all nitrogen atoms for primary and secondary amine groups, respectively. The SP modified CSOSA showed strong DNA condensation capability and obviously enhanced proton binding ability especially at about pH 5.0, which significantly promoted the escape of SP-CSOSA/pDNA complexes from endo-lysosoms. Moreover, the transfection efficiency at the N/P ratio of 10 could compete with that of Lipofectamine 2000 and PEI 25K, but with lower cytotoxicities. The therapeutic wild type p53 gene transfected by the SP-CSOSA polymer restored the function of aberrant p53 gene and induced obvious cell apoptosis and G1 phase arrest. We concluded that the new vector SP-CSOSA polymer proved to be a potential delivery system for gene therapy. PMID:27289311

    Salad Bowl and Waldmann's Green leaf lettuce (Lactuca sativa L.) were exposed to photosynthetic photon flux densities (PPFDs) of 444 or 889 micromol/s per sq m for 20 hrs/day under a diurnal temperature regime of 25-C days/15-C nights or 20-C days/15-C nights. Leaf dry weight of both cultivars was highest under the high PPFD/warm temperature regime and lowest under the low PPFD/cool temperature regime. Waldmann's Green yielded more than did Salad Bowl at 889 micromol/s per sq m and 25-C days/20-C nights. Under high PPFD, both cultivars yielded better with 25-C days/25-C nights than with 25-C days/20-C nights, although relative growth rates were the same under both temperature regimes.

    Large numbers of bacteria and viruses when seeded into household toilets were shown to remain in the bowl after flushing, and even continual flushing could not remove a persistent fraction. This was found to be due to the adsorption of the organsims to the porcelain surfaces of the bowl, with gradual elution occuring after each flush. Droplets produced by flushing toilets were found to harbor both bacteria and viruses which had been seeded. The detection of bacteria and firuses falling out onto surfaces in bathrooms after flushing indicated that they remain airborne long enough to settle on surfaces throughout the bathroom. Thus, there is a possibility that a person may acquire an infection from an aerosol produced by a toilet. PMID:169732

    The coloration of animals in nature is sometimes based on their structure rather than pigments. Structural coloration based on diffraction, multilayer reflection, cholesteric analogues or photonic crystal-like structures is pervasive especially in the world of insects. The color of Papilio palinurus results from microbowl lined with a multilayer of air and chitin. The green color is the result of color mixing of the yellow light reflecting from the bottom of the bowl and the blue light reflecting from the sides of the bowl. We have used breath figure templated assembly as the starting point to mimic the structure of Papilio palinurus. We were able to produce microbowls which were then coated with a multilayer of alternating titanium oxide and aluminum oxide. The resulting structure exhibits the same color mixing as the original butterfly structure does.

    Full Text Available Food is a major aspect of pet care; therefore, ensuring that pet foods are not only healthful but attractive to companion animals and their owners is essential. The petfood market remains active and requires ongoing evaluation of the adaptation and efficiency of the new products. Palatability—foods’ characteristics enticing animals and leading them to consumption—is therefore a key element to look at. Based on the type of information needed, different pet populations (expert or naïve can be tested to access their preference and acceptance for different food products. Classical techniques are the one-bowl and two-bowl tests, but complementary (i.e., operant conditioning and novel (i.e., exploratory behavior approaches are available to gather more information on the evaluation of petfood palatability.

  2. Marangoni effect induced micro/nano-patterning on Sb2Te3 phase change thin film by laser pulse

    International Nuclear Information System (INIS)

    Thermocapillary and chemicapillary effects are known to coexist in a material molten pool when irradiated by a pulse laser. According to the effects, we fabricate various patterns with different shapes on a Sb2Te3 phase change thin film by precisely adjusting the pulse energy. In this process, the laser power is fixed at 5.0 mW, and the pulse width is adjusted from 100 ns to 5 ns. The shape of the patterns gradually changes from a dimple-bowl shape, a dome shape, a ''Sombrero'' shape to a deep-bowl shape following an increase in the pulse energy, which corresponds to the crystallization-threshold, bump-threshold, rupture-threshold, and ablation-threshold of the material. The different patterns are the results of the competition between the thermocapillary and chemicapillary effects in the molten pool, which determine the nature of the flow and lead to the different patterns in different laser parameters.

    Full Text Available As part of measures being taken against global warming, the reduction of CO2 emissions by retrofitting for water-saving fittings in homes is spreading throughout the world. However, although this retrofitting reduces the environmental impact at the use stage, it generates new impacts at the production and disposal stages. In addition, there has been little research that discusses the reduction in environmental impact obtained by retrofitting from the viewpoint of the overall life cycle of such fittings. In this paper, an evaluation of the environmental impact of retrofitting in terms of the entire life cycle was carried out for toilet bowls and showerheads. The findings show that even for a toilet bowl that generates a large environmental load at the production stage, there is no overall increase in the environmental impact by retrofitting for the average usable life of 20 years.

    This case report describes a 10-year-old boy who presented with radiating pain (Visual Analog Scale score of 7.2 cm) down his left groin and was eventually diagnosed to have osteitis pubis. History revealed that he was exceeding the workload guidelines of bowling for a fast bowler. Examination findings were left sacro-iliac joint dysfunction, reduced left internal rotation of the hip, tightness of bilateral hip flexors and poor motor control of the lumbo-pelvic muscles. Physical therapy was aimed at correcting the sacro-iliac joint dysfunction, increasing the hip range of motion and muscle length along with exercises aimed at improving the lumbopelvic stability. The patient had complete resolution of pain by the ninth week and returned to fast bowling without any discomfort. PMID:23270404

    Full Text Available This research evaluated the quality of Eucalyptus dunnii sawn wood for use in the lumber industry. Logs of 25 and 30 cm of diameter were used, broken down according to two methods. The first method produced boards with tangential faces and the other method produced boards with radial faces. Defects such as crooking, bowling, cupping, and index of cracks in boards, in two humidity conditions, were appraised. Defects were appraised before and after drying, i.e. after reaching the humidity balance. The crooking was more intense in radial boards. The bowling was similar in the two studied systems. Cupping only happened in tangential boards after drying. Cracks were more intense in tangential break down, presenting larger evolution after drying, when compared with radial break down. The breaking down system envisaging boards with radial faces presented pieces of better conditions for industrial purposes.

A region is identified where the direct effect on the flow of the component of the buoyancy force tangential to the body surface is comparable to the indirect effect of the component normal to the surface, which acts through the gradient of the nonuniform pressure that it induces in the boundary layer. Analysis of this region provides a description ...

    2002-03-13

    The cation N(2)H(7)(+) has been stabilized in a largely hydrophobic supramolecular environment and characterized in the solid state. The cation is situated in the bowl-shaped cavity of calix[4]arene. All of the hydrogen atoms are clearly discernible owing to high-quality X-ray data as well as lack of disorder and symmetry-imposed ambiguity. It appears that electrostatic interactions play a critical role in stabilizing the structure. PMID:11878959

    m-Terphenyls are bowl-shaped molecules that have been shown to be effective ligands for main group and transition metal complexes with unusual coordination environments. Many m-terphenyl complexes are formed via direct element-carbon bonds, but the chemistry of substituted m-terphenyls, in which the primary interaction is through a functional group, is relatively unexplored. The introduction of functional groups allows for more varied coordination modes, and therefore, more varied structures....

  14. The nonholonomic and chaotic nature of a rolling isolation system

    Science.gov (United States)

    Harvey, P. Scott; Gavin, Henri P.

    2013-07-01

    This paper presents the modeling of a rolling isolation platform used to protect objects from the hazards of horizontal shaking. The platform is built from four pairs of recessed steel bowls: four concave-up, attached to a shaking floor via a steel frame, and four concave-down, attached to the isolated object via a steel frame. Four steel ball-bearings, located between these bowls, allow the bottom- and top-frames to roll with respect to one another. In order for the four ball-bearings to remain in contact with the bowls during times of large angular rotation, the top-frame is assumed to conform to a saddle shape. The kinematics of the rolling contact impose a set of eight nonholonomic constraints to the translational and rotational dynamics of the platform center. The nonholonomic equations of state are found from the fundamental form of Lagrange's equation, which incorporates velocity constraints via Lagrange multipliers. A viscous damping model calibrated to experimental free-responses depends upon the mass of the isolated object. Precise photogrammetric measurements of a sample of these steel bowls provide the data required to calibrate the potential energy function for this system. It is shown that for the non-quadratic potential energy function of this particular system, free response trajectories are strongly sensitive to slight perturbations in initial conditions, and that the system is, in fact, chaotic. Even in the absence of any mass or stiffness eccentricity, translational and rotational motions are nonlinearly coupled through the constraint of slip-free rolling. Uni-axial models cannot be used to predict responses of these systems.

    2016-05-01

    Full Text Available Regardless of the intrinsic graphic complexity of the spaghetti bowl effect, the direct flow mapping of large matrices often appears to be compact, characteristic of an amalgam effect of the represented information. This effect is the result of the mix between different types of information within a single figure: information on the dynamics of the flow system and those rooted in the system's stability. To overcome this effect, it is necessary to decompose the matrix before mapping it.

    The aim of this study is to see how geometry generated turbulence affects the Rate of Heat Release (ROHR) in an HCCI engine. HCCI combustion is limited in load due to high peak pressures and too fast combustion. If the speed of combustion can be decreased the load range can be extended. Therefore two different combustion chamber geometries were investigated, one with a disc shape and one with a square bowl in piston. The later one provokes squish-generated gas flow int...

  18. Atypical pit craters on Mars: New insights from THEMIS, CTX, and HiRISE observations

    Science.gov (United States)

    Cushing, Glen E.; Okubo, Chris H.; Titus, Timothy N.

    2015-06-01

    More than 100 pit craters in the Tharsis region of Mars exhibit morphologies, diameters, and thermal behaviors that diverge from the much larger bowl-shaped pit craters that occur in most regions across Mars. These Atypical Pit Craters (APCs) generally have sharp and distinct rims, vertical or overhanging walls that extend down to their floors, surface diameters of ~50-350 m, and high depth to diameter (d/D) ratios that are usually greater than 0.3 (which is an upper range value for impacts and bowl-shaped pit craters) and can exceed values of 1.8. Observations by the Mars Odyssey Thermal Emission Imaging System (THEMIS) show that APC floor temperatures are warmer at night and fluctuate with much lower diurnal amplitudes than nearby surfaces or adjacent bowl-shaped pit craters. Kīlauea volcano, Hawai'i, hosts pit craters that formed through subsurface collapse into active volcanic dikes, resulting in pits that can appear morphologically analogous to either APCs or bowl-shaped pit craters. Partially drained dikes are sometimes exposed within the lower walls and floors of these terrestrial APC analogs and can form extensive cave systems with unique microclimates. Similar caves in Martian pit craters are of great interest for astrobiology. This study uses new observations by the Mars Reconnaissance Orbiter High Resolution Imaging Science Experiment (HiRISE) and Context Camera to refine previous work where seven APCs were described from lower resolution THEMIS visible wavelength observations. Here we identify locations of 115 APCs, map their distribution across the Tharsis region, characterize their internal morphologies with high-resolution observations, and discuss possible formation mechanisms.

    Full Text Available Abstract. The study examines egalitarianism policies in terms of the relationship between labor and capital and extends the model developed by the economist Bowles. We introduce the demand factor to the Bowles model (2012, which discussed the effectiveness of the income and asset redistribution policies in a global economy. The improvement of productivity and the decrease in the ratio of monitoring labor through asset-based redistribution increase the real wage rate because of its lure for foreign capital. At this point in the Bowles model, the labor supply increases and then employment increases. In contrast, in our model, with the addition of the demand factor, the improvement of productivity increases employment, but the decrease in monitoring labor does not always increase employment as both demand and supply increase. This means that asset-based redistribution in a global economy is not always effective.Keywords. Egalitarianism, Redistribution, Effective demand, Globalization.JEL. E12, F60, J80, J88.

    The ability to utilize individual molecules and molecular assemblies as data storage elements has motivated scientist for years, concurrent with the continuous effort to shrink a size of data storage devices in microelectronics industry. One of the critical issues in this effort lies in being able to identify individual molecular assembly units (patterns), on a large scale in an automated fashion of complete information extraction. Here we present a novel method of applying machine learning techniques for extraction of positional and rotational information from scanning tunneling microscopy (STM) images of π-bowl sumanene molecules on gold. We use Markov Random Field (MRF) model to decode the polar rotational states for each molecule in a large scale STM image of molecular film. We further develop an algorithm that uses a convolutional Neural Network combined with MRF and input from density functional theory to classify molecules into different azimuthal rotational classes. Our results demonstrate that a molecular film is partitioned into distinctive azimuthal rotational domains consisting typically of 20-30 molecules. In each domain, the ``bowl-down'' molecules are generally surrounded by six nearest neighbor molecules in ``bowl-up'' configuration, and the resultant overall structure form a periodic lattice of rotational and polar states within each domain. Research was supported by the US Department of Energy.

  1. A multi-channel magnetic induction tomography measurement system for human brain model imaging

    International Nuclear Information System (INIS)

    This paper proposes a multi-channel magnetic induction tomography measurement system for biological conductivity imaging in a human brain model. A hemispherical glass bowl filled with a salt solution is used as the human brain model; meanwhile, agar blocks of different conductivity are placed in the solution to simulate the intracerebral hemorrhage. The excitation and detection coils are fixed co-axially, and the axial gradiometer is used as the detection coil in order to cancel the primary field. On the outer surface of the glass bowl, 15 sensor units are arrayed in two circles as measurement parts, and a single sensor unit for canceling the phase drift is placed beside the glass bowl. The phase sensitivity of our system is 0.204°/S m−1 with the excitation frequency of 120 kHz and the phase noise is in the range of −0.03° to +0.05°. Only the coaxial detection coil is available for each excitation coil; therefore, 15 phase data are collected in each measurement turn. Finally, the two-dimensional images of conductivity distribution are obtained using an interpolation algorithm. The frequency-varying experiment indicates that the imaging quality becomes better as the excitation frequency is increased

  2. The UPM high temperature solar collector current status

    International Nuclear Information System (INIS)

    The high temperature solar energy research at Universiti Putra Malaysia (UPM) is an attempt to study the merits of the fixed aperture optics collector for the equatorial region using the concept of the fixed mirror distributed focus (FMDF). The general objective is to look for an alternative source of clean energy and a practical method of converting this energy to usable form for the projected industrialisation program of the country. The FMDF uses a stationary hemisphere bowl to capture the solar irradiance. The UPM bowl has a rim angle of 120 0 with radius of curvature of 27.9 m. This corresponds to an aperture diameter of 48 m and submerges 5.1 m in the ground. The bowl will later be tiled with 2446 square meters of mirror to form a spherical shape. And therefore will be able to collect about 1 MW of solar irradiance at the conical focus formed along the direction of the radius (high concentrated region) which then can be harnessed by different means. In this paper, we will report the current status and future works of the project, under construction at the site. We anticipate that the project will be completed and operated by the year 2000.

  3. -Stacking interactions between G-quartets and circulenes: A computational study

    Indian Academy of Sciences (India)

    A K Jissy; J H V Ramana; Ayan Datta

    2011-11-01

    Structures of planar and bowl-shaped circulenes as well as their stacks with G-quartet (G4) have been investigated through dispersion-corrected Density Functional Theory (DFT-D). The binding energies are substantial ∼10 kcal/mol with d ∼3.5 Å between the stacking rings. The calculations show that G4 binds much more effectively to planar circulenes as compared to bowl shaped molecules. The strength of binding between a G-quartet and a non-planar circulene molecule depends on the orientation of the circulene (concave or convex) with respect to G-quartet. An AIM analysis of the M05-2X wave-functions has also been performed to confirm the presence of weak intermolecular interactions between guanine quartets and circulenes. Apart from -stacking interactions, the concave bowl-shaped circulenes also interact with G4 through C-H $\\cdots$ interactions. The charge transport properties between the two moieties have also been analysed through effective transport integral. The calculations provide an understanding for the basis of molecular recognition by G4 for non-planar systems.

  4. Analysis and Optimization of the Production Process of Cooked Sausage Meat Matrices

    Science.gov (United States)

    Diez, L.; Rauh, C.; Delgado, A.

    2010-09-01

    In the production of cooked sausages a critical step for product quality is the cutting process, where the comminuting and mixing of meat, fat, ice and spices are carried out. These processes take usually place in bowl cutters, which main control parameters are the working time, knife geometry (shape and sharpness) and rotational velocities of the knives and the bowl. The choice of the geometry and sharpness of the knives influences not only the meat matrix properties (mechanical, rheological, etc.) and, as a consequence, the sensory value of the sausages (size of connective tissue particles, water binding, etc.), but also the energetic demand for the production. However, the cutting process proves to be understood only fragmentarily due to the complex colloid chemical and mechanical behavior of the product. This is documented on the one hand by numerous knife types on the market, extremely empirical approach during determination of geometry and process parameters in practice as well as, on the other hand, by contradictory statements and explanation approaches of observed phenomena present in literature. The present contribution applies numerical simulations to analyze thermo fluid mechanical phenomena, e.g. shear stresses, during the cutting process of the non-Newtonian meat matrix. Combining these results with selected experimental investigations from literature, e.g. sensory properties, knife geometry, velocity of the knife and bowl, improvements of the cutting and mixing process are proposed using cognitive algorithms (Artificial neural networks) aiming at an optimization regarding energy and time demand and product quality.

In this paper, 2.2L, multi cylinder diesel engine have been tested for four different piston bowls designed for compression ratio of CR 15.5 to improve in cylinder performance and reduce emissions. These combustion chambers were verified in CFD at two full load points. 14 mode points have been derived using vehicle model run in AVL CRUISE software as per NEDC cycle based on time weightage factor. Base engine with compression ratio CR16.5 for full load performance and 14-mode points on Engine test bench was taken as reference for comparison. The bowl with flat face on bottom corner has shown reduction 25% and 12 % NOx emissions at 1500 and 3750 rpm full load points at same level of Soot emissions. Three piston bowls were tested for full load performance and 14 mode points on engine test bench and combustion chamber ‘C’ has shown improvement in thermal efficiency by 0.8%. Combinations of cooled EGR and combustion chamber ‘C’ with geometrical changes in engine have reduced exhaust NOx, soot and CO emissions by 22%, 9 % and 64 % as compared to base engine at 14 mode points on engine test bench.

    'This project has as its focus the design and synthesis of polyammonium macrocyclic receptors for oxoanions of environmental importance. The basic research aspects of this project involve synthesis (and the search for improved synthetic methods), solid state structure determination and thermodynamics studies (to ascertain structural criteria for and strength of anion binding), and molecular dynamics simulations (to assess solution characteristics of the interactions between anions and their receptors). Applications-oriented goals include the fabrication of more efficient anion-selective electrodes and the use of these compounds in liquid- liquid separations. The latter goal is the subcontract with Bruce Moyer at Oak Ridge National Laboratory. This first year the authors have focused on nitrates and phosphates. Considerable progress has been made in the basic areas of synthesis, solid state Structure, and molecular dynamics. Anion selective electrodes have also be made which show promising selectivities for oxoanions of interest. Below are described the major findings and significance in the categories of synthesis, structure and molecular dynamics, and electrode studies. Synthesis. The synthesis of polyaza macrocycles which are the focus of these studies is often tedious and time-consuming. A major breakthrough which the authors have made this year is to identify other polyaza macrocycles, which also bind the desired anions, but which are simpler to synthesize via a two step Schiff base/reduction process with high yields. This is truly significant since now the authors can obtain large quantities of the macrocycles and do multiple studies at once (crystallizations, thermodynamics, electrode, and eventually separations). Most of their studies to date have focused on monocyclic systems, but they are now beginning to examine bicyclic macrocycles, which can be synthesized by the same method starting with the tetraamine known as tren.'

    Experimental work is continuing on four separate projects related to coal conversion processes. The direct digital control of exothermic multiphase reactions is being studied in an experimental adiabatic flow reactor. The existence of two stable steady states for the Fischer-Tropsch reaction network at the same temperature and feed condition has been verified and quantified. Various absorbents for SO/sub 2/ and NO/sub X/ are being studied. The absorption of NO/sub 2/ by methanol and N-cyclohexyl-2-pyrrolidone has been extensively examined. Preliminary data have been obtained with triethylene-tetraamine. Hindered amines will be studied next. Procedures for the preparation of liquid membranes have been tested and the incorporation of hindered amines in them will now be examined. Isotopic switching is being used to study the way in which promoters affect supported metal catalysts. With improved resolution from the mass spectrometer, early quantitative results give indications of three different surface species and of non-statistical ingrowth of /sup 13/C into the product molecules. A program for the study of the extraction of coal and oil shale using supercritical fluids is being carried out. The effect of the presence of piperidine on the amount of toluene solubles produced by supercritical extraction of coal with toluene/piperidine mixture has been determined. A new kinetic model for the extraction/liquefaction of coal by supercritical toluene and THF has been developed and proven satisfactory. Bruceton coal and Hi Na lignite have been extracted with supercritical water. 3 references, 7 figures, 6 tables.

    Demotate is a new tetraamine-functionalised [Tyr{sup 3}]octreotate derivative that binds technetium-99m with a high efficiency under mild conditions. The resulting radioligand, [{sup 99m}Tc]Demotate, forms in a high purity and is stable for at least 6 h after labelling. The affinity of the unlabelled peptide for somatostatin receptors is high (IC{sub 50}=0.13 nM) and comparable to that of [Tyr{sup 3}]octreotate or [Tyr{sup 3}]octreotide, as demonstrated by competition binding experiments in rat brain cortex or AR42J cell membrane preparations. An equally very high affinity (K{sub d}=0.07 nM) was exhibited by [{sup 99m}Tc/{sup 99g}Tc]Demotate during saturation binding experiments using rat brain cortex membrane homogenates. The radioligand resisted hydrolytic degradation in mouse plasma and was excreted intact in mouse urine. In vivo, [{sup 99m}Tc]Demotate cleared very rapidly from non-target tissues into the bladder via the kidneys, while radioactivity uptake in target organs was very high. In mice bearing the experimental AR42J tumour, [{sup 99m}Tc]Demotate demonstrated a very high tumour uptake at 1 h p.i. (25%ID/g) that remained high (20%ID/g) at 4 h p.i. This uptake could be effectively blocked by co-injection of a high dose of [Tyr{sup 3}]octreotate together with the radioligand. High-quality planar and single-photon emission tomographic images were acquired 1 h after injection of [{sup 99m}Tc]Demotate in tumour-bearing mice, illustrating the excellent properties of this agent for somatostatin receptor tumour imaging.

  9. Inverse modeling using PS-InSAR for improved calibration of hydraulic parameters and prediction of future subsidence for Las Vegas Valley, USA

    Burbey, T. J.; Zhang, M.

    2015-11-01

    Las Vegas Valley has had a long history of surface deformation due to groundwater pumping that began in the early 20th century. After nearly 80 years of pumping, PS-InSAR interferograms have revealed detailed and complex spatial patterns of subsidence in the Las Vegas Valley area that do not coincide with major pumping regions. High spatial and temporal resolution subsidence observations from InSAR and hydraulic head data were used to inversely calibrate transmissivities (T), elastic and inelastic skeletal storage coefficients (Ske and Skv) of the developed-zone aquifer and conductance (CR) of the basin-fill faults for the entire Las Vegas basin. The results indicate that the subsidence observations from PS-InSAR are extremely beneficial for accurately quantifying hydraulic parameters, and the model calibration results are far more accurate than when using only water-levels as observations, and just a few random subsidence observations. Future predictions of land subsidence to year 2030 were made on the basis of existing pumping patterns and rates. Simulation results suggests that subsidence will continue in northwest subsidence bowl area, which is expected to undergo an additional 11.3 cm of subsidence. Even mitigation measures that include artificial recharge and reduced pumping do not significantly reduce the compaction in the northwest subsidence bowl. This is due to the slow draining of thick confining units in the region. However, a small amount of uplift of 0.4 cm is expected in the North and Central bowl areas over the next 20 years.

  10. An archaeological data assessment of Persian ethnicity in Lydia

    Directory of Open Access Journals (Sweden)

    Hatice Kalkan,

    2014-04-01

    Full Text Available The present paper assesses the terracotta sarcophagus and its associated context discovered in Ödemiş/Yeniceköy in the Lydian region. This paper questions what these group of findings, including two lekythoi and one bronze Achaemenid bowl as burial gifts, mean in terms of the presence of a Persian ethnicity in the region which is a relatively late discovery. Likewise, Achaemenid bowls had been found among the funerary gifts beside a similar sarcophagus during the Beydağ tumulus excavations held in 2014 by the Ödemiş Museum Directorate, a discovery which made it necessary to investigate the possibility of an Anahita-related tradition of the burial cult in this site. A similar discovery was made in the excavations of Mount Nif, with this very type of bowl being unearthed in the contexts together with the burials, which provides support to our hypothesis. This hypothesis about the Persian ethnicity that was already present during the Hellenistic and Roman periods is not only based on evidence from the inscriptions, coins, and ancient sources, but now it can also be traced in terms of material culture thanks to the new evidence in question, which is also important in revealing the Persian influence upon burial traditions. The popularity of the Anahita cult that survived from the Achaemenid period well into the Roman era created an impact influencing not only “Lydian Iranians” but also the entire local and Roman population. However, the presence of Persian population here has largely to do with the Anahita cult and its practices. Therefore, occasional retrieval of philalai, i.e. the most commonly-known cultic form of Achaemenid culture, together with burials should be considered as strong archaeological data in ascertaining particularly the Persian ethnicity during the Hellenistic Period.

  11. The effects of juvenile stress on anxiety, cognitive bias and decision making in adulthood: a rat model.

    Directory of Open Access Journals (Sweden)

    Nichola M Brydges

    Full Text Available Stress experienced in childhood is associated with an increased risk of developing psychiatric disorders in adulthood. These disorders are particularly characterized by disturbances to emotional and cognitive processes, which are not currently fully modeled in animals. Assays of cognitive bias have recently been used with animals to give an indication of their emotional/cognitive state. We used a cognitive bias test, alongside a traditional measure of anxiety (elevated plus maze, to investigate the effects of juvenile stress (JS on adulthood behaviour using a rodent model. During the cognitive bias test, animals were trained to discriminate between two reward bowls based on a stimulus (rough/smooth sandpaper encountered before they reached the bowls. One stimulus (e.g. rough was associated with a lower value reward than the other (e.g. smooth. Once rats were trained, their cognitive bias was explored through the presentation of an ambiguous stimulus (intermediate grade sandpaper: a rat was classed as optimistic if it chose the bowl ordinarily associated with the high value reward. JS animals were lighter than controls, exhibited increased anxiety-like behaviour in the elevated plus maze and were more optimistic in the cognitive bias test. This increased optimism may represent an optimal foraging strategy for these underweight animals. JS animals were also faster than controls to make a decision when presented with an ambiguous stimulus, suggesting altered decision making. These results demonstrate that stress in the juvenile phase can increase anxiety-like behaviour and alter cognitive bias and decision making in adulthood in a rat model.

    2016-09-01

    We describe a low-cost yet experimentally challenging method to measure the acceleration of gravity, g, using a liquid in a rotating bowl and a laser pointer. The idea underpinning this novel method is that the rotating liquid surface will form a parabolic reflector which will focus light into a unique focal point. By measuring the height of the focal point, g could be determined to 9.78+/- 0.13 m s‑2. We discuss the pedagogical merits of this method compared to more traditional methods for measuring g, and how it can be implemented as an experimental problem at different educational levels.

    Basu, Saptarshi; Tijerino, Erick; Kumar, Ranganathan

    2013-04-01

    Hollow structures with unique morphologies form due to particle agglomeration in acoustically levitated nanofluid functional droplets when subjected to external heating. The final diameter of the structure depends only on the ratio of agglomeration to evaporation time scales for various nanoparticle laden droplets, and not on the type of the suspended particles. These time scales depend only on nanoparticle concentration. This valuable information may be exploited to form microstructures with desired properties from ceramic compounds. Phase diagrams for alumina and silica droplets indicate the transition from a bowl to ring structure depending on concentration.

    Full Text Available In limited overs cricket, efficiency plays a significant role in team success. Batsmen especially are under pressure to score quickly rather than in large quantities because only 50 overs are available per innings. This paper uses data envelopment analysis (DEA and stochastic multicriteria acceptability analysis (SMAA to assess the efficiency with which players at the 2011 Cricket World Cup converted inputs (balls faced or bowled into performance outputs. The effect that non-discretionary variables like the cricketing resources available to a player have on his efficiency is controlled for, allowing for a fairer assessment across players from different countries.

    1973-01-01

    Martian sedimentation is primarily aeolian with the principal source areas being the cratered highlands. Lighter albedo in areas of sedimentation may be due to minerals of smaller grain size and/or lighter specific gravity. Martian erosion sedimentation seems to be active as evidenced by removal and/or burial of ejecta mounds and ray ejecta patterns around fresh bowl shaped craters. It is suggested that at least some chaotic terrain may be formed by aeolian removal of material in areas of closely spaced faulting. Transitional areas between uplands and basins are sometimes muted by down slope winds.

  9. Update on subsidence at the Wairakei-Tauhara geothermal system, New Zealand

    Science.gov (United States)

    Allis, R.; Bromley, C.; Currie, S.

    2009-01-01

    The total subsidence at the Wairakei field as a result of 50 years of geothermal fluid extraction is 15 ?? 0.5 m. Subsidence rates in the center of the subsidence bowl have decreased from over 450 mm/year during the 1970s to 80-90 mm/year during 2000-2007. The location of the bowl, adjacent to the original liquid outflow zone of the field, has not changed significantly. Subsidence at the Tauhara field due to Wairakei production was not as well documented in the early years but appeared later and has been less intense than at Wairakei. Total subsidence of 2.6 ?? 0.5 m has also occurred close to the original liquid outflow zone of this field, and maximum subsidence rates in this area today are in the 80-100 mm/year range. In the western part of the Wairakei field, near the area of hot upflow, subsidence rates have approximately doubled during the last 20 years to 30-50 mm/year. This increase appears to be have been caused by declining pressure in the underlying steam zone in this area, which is tapped by some production wells. At Tauhara field, two areas of subsidence have developed since the 1990s with rates of 50-65 mm/year. Although less well-determined, this subsidence may also be caused by declining pressure in shallow steam zones. The cause of the main subsidence bowls in the Wairakei-Tauhara geothermal system is locally high-compressibility rocks within the Huka Falls Formation (HFF), which are predominantly lake sediments and an intervening layer of pumice breccia. At Wairakei, casing deformation suggests the greatest compaction is at 150-200 m depth. The cause of the large compressibility is inferred to be higher clay content in the HFF due to intense hydrothermal alteration close to the natural fluid discharge areas. Future subsidence is predicted to add an additional 2-4 m to the Wairakei bowl, and 1-2 m elsewhere, but these estimates depend on the assumed production-injection scenarios.

    2010-01-01

    Carbon dioxide is a dangerous volcanic gas. When carbon dioxide seeps from the ground, it normally mixes with the air and dissipates rapidly. However, because carbon dioxide gas is heavier than air, it can collect in snowbanks, depressions, and poorly ventilated enclosures posing a potential danger to people and other living things. In this experiment we show how carbon dioxide gas displaces oxygen as it collects in low-lying areas. When carbon dioxide, created by mixing vinegar and baking soda, is added to a bowl with candles of different heights, the flames are extinguished as if by magic.

    Full Text Available The aim of this study was to evaluate binders to improve the flowability of granulates and compactibility of Metformin HCL (Met using the moist aqueous granulation (MAG process. The effect of the binder moisture content on granulate and tablet quality was also evaluated. Vinylpyrrolidone–vinyl acetate copolymer (Kollidon VA64 fine: VA64, polyvidone (Povidone K12: PVP, hydroxypropyl cellulose (HPC SSL SF: HPC and hydroxypropyl methylcellulose (Methocel E5 LV: HPMC were evaluated as binders. These granulates, except for HPMC, had a lower yield pressure than Met active pharmaceutical ingredient (API. HPMC Met was not sufficiently granulated with low water volume. No problems were observed with the VA64 Met granulates during the tableting process. However, HPC Met granulates had a bowl-forming tendency, and PVP Met granulates had the tendency to stick during the tableting process. These bowl-forming and sticking tendencies may have been due to the low moisture absorbency of HPC and the high volume of bound water of PVP, respectively. VA64 Met granulates had the highest ambient moisture content (bulk water, bound water and moisture absorbency. It was concluded that the type of binder used for the Met MAG process has an impact on granulate flow and compactibility, as well as moisture absorbency and maintenance of moisture balance.

This dramatic change in the demographics of this clinical population represents unique challenges for patients, health care providers, and society-at-large. Fortunately, because of highly active antiretroviral therapy (HAART and healthy lifestyle choices, it is now possible for many infected with HIV to age successfully with this disease; however, this depends upon one’s definition of successful aging. It is proposed that successful aging is composed of eight factors: length of life, biological health, cognitive efficiency, mental health, social competence, productivity, personal control, and life satisfaction. Unfortunately, HIV and medication side effects can compromise these factors, thus diminishing one’s capacity to age successfully with this disease. This article explores how HIV, medication side effects from HAART, and lifestyle choices can compromise the factors necessary to age successfully. Implications for practice and research are posited.Keywords: HIV, AIDS, successful aging, spirituality, depression, hardiness

    1985-11-01

    A simple method with poliovirus as the model was developed for recovering human enteric viruses from aerosols. Filterite filters (pore size, 0.45 micron; Filterite Corp., Timonium, Md.) moistened with glycine buffer (pH 3.5) were used for adsorbing the aerosolized virus. No virus passed the filter, even with air flow rates of 100 liters/min. Virus recovery from the filter was achieved by rapid elution with 800 ml of glycine buffer, pH 10. The virus in the primary eluate was reconcentrated by adjusting the pH to 3.5, adding AlCl3 to 0.0005 M, collecting the virus on a 0.25-micron-pore Filerite disk (diameter, 25 mm) and and eluting with 6 ml of buffer, pH 10. With this method, virus could be detected regularly in aerosols produced by flushing when 3 X 10(8) PFU of poliovirus were present in the toilet bowl. Poliovirus-containing fecal material from two of four infants who had recently received oral polio vaccine also yielded virus in the aerosols when feces containing 2.4 X 10(7) to 4.5 X 10(7) PFU of virus had been added to the toilet bowl. Persons infected with a variety of natural enteric viruses are known to excrete this amount of virus in their daily stools. PMID:3004329

    Full Text Available Intestinal hamartomatous polyps represent a rare cause of proximal bowl obstruction and hemorrage in adults. Till 2009, there were cited less than 15 cases in the literature. Here we present the clinical observation of a patient, admitted in our clinic with the clinical diagnosis of proximal bowl obstruction, accompanied by upper digestive hemorrhage exteriorized through hematemesis, where the surgical intervention performed had showed the presence of an intestinal invagination developed upon an enteral polypod mass, along with some other enteral intraluminal polypoid masses, having different sizes, and were distributed upon a distance of 60 cm from the ligament of Treitz. A segmental eneterectomy keeping in view of the oncologicaly safety margins was performed, along with an end-to-end enetero-enteral anastomosis to restore the bowel continuity. The histopathological exam of the specimen revealed the presence of some hamartomatous polyps, along with the development of a tubular adenocarcinoma at the level of one of these polyps. Association of enteral hamartomatous polyps with enteral carcinoma and the possibility of their malignant transformation is a matter of debate in the literature, where there can be found debates supporting as well as debates negating this theory.

    2004-07-01

    We are developing a scanned focused ultrasound system for hyperthermia treatment of breast cancer. Focused ultrasound has significant potential as a therapy delivery device because it can focus sufficient heating energy below the skin surface with minimal damage to intervening tissue. However, as a practical therapy system, the focal zone is generally quite small and requires either electronic (in the case of a phased array system) or mechanical steering (for a fixed bowl transducer) to cover a therapeutically useful area. We have devised a simple automated steering system consisting of a focused bowl transducer supported by three vertically movable rods which are connected to computer controlled linear actuators. This scheme is particularly attractive for breast cancer hyperthermia where the support rods can be fed through the base of a liquid coupling tank to treat tumors within the breast while coupled to our noninvasive microwave thermal imaging system. A MATLAB routine has been developed for controlling the rod motion such that the beam focal point scans a horizontal spiral and the subsequent heating zone is cylindrical. In coordination with this effort, a 3D finite element thermal model has been developed to evaluate the temperature distributions from the scanned focused heating. In this way, scanning protocols can be optimized to deliver the most uniform temperature rise to the desired location.

  18. Curved-Line Cutting Using a Flexible Circular Saw

    Science.gov (United States)

    Yamada, Yohei; Osumi, Nobuyuki; Takasugi, Akio; Sasahara, Hiroyuki

    We propose a flexible circular saw for high-speed cutting of curved lines in carbon fiber-reinforced plastic (CFRP). A conventional circular saw is appropriate for straight line cutting, but it cannot be applied to curved line cutting because of the interference between the saw body and the machined surface. To eliminate this problem, the flexible circular saw is deflected into a bowl shape by circular forced displacement, and the cross-section of the saw becomes a circular arc. A curved line can be cut by the bowl-like-deflection. The deflection shape is very important to realize the curved-line cutting without interference. We investigated the deflection of the flexible circular saw by a finite element method (FEM) analysis. Suitable slit shapes for the saw body are also proposed, based on the FEM results regarding stress in the saw body, the minimum radius of curvature, and the effects of cutting force and centrifugal force and eigenvalue. We also conducted a curved-line cutting test on a CFRP plate, and we found that the flexible circular saw can cut curved lines with high accuracy and high speed without interference between the saw body and the machined surface.

    PIV data obtained in a transparent motored Diesel engine are presented and discussed in this paper. These data are obtained in severe thermodynamical conditions in the cylinder during the cycle and in the bowl at top dead center (TDC). Moreover, they are obtained at consecutive cycles. We first consider the flow in the middle of the compression phase. In particular, instantaneous velocity fields are analyzed and classified by computing circulation statistics. We show that the structure of the swirling motion is varying very significantly from ''vortex type'' to ''annular type'' from one cycle to another. In-cycle and inter-cycle statistics of these structure fluctuations are discussed. For example, we do not find any cycle-to-cycle correlation. The circulation data are then decomposed by using a proper orthogonal decomposition of the statistical set. The possibility of low order description of this kind of flow is considered. Finally, we study the in-bowl flow at the very end of the compression phase. The quantitative analysis based on circulation statistics show that we still detect strong structure fluctuations of the swirling flow at TDC and that the intensity of these fluctuations have not decreased after the squish phase.

  2. Nanoparticle agglomeration in an evaporating levitated droplet for different acoustic amplitudes

    2013-01-01

    Radiatively heated levitated functional droplets with nanosilica suspensions exhibit three distinct stages namely pure evaporation, agglomeration, and finally structure formation. The temporal history of the droplet surface temperature shows two inflection points. One inflection point corresponds to a local maximum and demarcates the end of transient heating of the droplet and domination of vaporization. The second inflection point is a local minimum and indicates slowing down of the evaporation rate due to surface accumulation of nanoparticles. Morphology and final precipitation structures of levitated droplets are due to competing mechanisms of particle agglomeration, evaporation, and shape deformation. In this work, we provide a detailed analysis for each process and propose two important timescales for evaporation and agglomeration that determine the final diameter of the structure formed. It is seen that both agglomeration and evaporation timescales are similar functions of acoustic amplitude (sound pressure level), droplet size, viscosity, and density. However, we show that while the agglomeration timescale decreases with initial particle concentration, the evaporation timescale shows the opposite trend. The final normalized diameter can be shown to be dependent solely on the ratio of agglomeration to evaporation timescales for all concentrations and acoustic amplitudes. The structures also exhibit various aspect ratios (bowls, rings, spheroids) which depend on the ratio of the deformation timescale (tdef) and the agglomeration timescale (tg). For tdefbowls and spheroids.

  3. Categorization of Attribution as a Technique for Determining the Percularities of a Linguistic Personality’s Individual Style

    Directory of Open Access Journals (Sweden)

    Vladislav Valeryevich Voskoboynikov

    2015-09-01

    Full Text Available The article deals with the issue of formalizing the individual style of an Englishspeaking journalist as exemplified in the categorization of attribution. The individual style is understood as a system of logic and semantic ways of representing the dominant personal implications of the author's conceptual system, objectified in their esthetic activities and suggesting individual transformation of verbal expressions. To study the individual style, it is proposed to use the methods of applied linguistics, namely, lexical statistics, for the analysis of text extracts of a certain author and their subsequent comparison with the results obtained on other writers' texts. The article gives the results of attribution category analysis and the peculiarities of lexical and thematic structure of a personality's vocabulary in the texts of English-speaking journalists Suzy Menkes and Hamish Bowles on the topic of fashion. Among the most frequent semantic groups are the descriptive categories of colour, toponymy, time, and size. The comparative analysis of the statistic charts has revealed that though various semantic groups are present in the texts of both journalists, the mini-corpus of texts by H. Bowles features the categories of shape and material more frequently than that of S. Menkes's texts rich in the descriptive categories.

    As part of a JCMT Legacy Survey of star formation in the Gould Belt, we present early science results for Taurus. CO J=3-2 maps have been secured along the north-west ridge and bowl, collectively known as L 1495, along with deep 13CO and C18O J=3-2 maps in two sub-regions. With these data we search for molecular outflows, and use the distribution of flows, HH objects and shocked H2 line emission features, together with the population of young stars, protostellar cores and starless condensations to map star formation across this extensive region. In total 21 outflows are identified. It is clear that the bowl is more evolved than the ridge, harbouring a greater population of T Tauri stars and a more diffuse, more turbulent ambient medium. By comparison, the ridge contains a much younger, less widely distributed population of protostars which, in turn, is associated with a greater number of molecular outflows. We estimate the ratio of the numbers of prestellar to protostellar cores in L 1495 to be ~ 1.3-2.3, and...

    In 1989, the Yaojiaquan site in Songjiang county, Shanghai city, was excavated by the Archaeology Section, Shanghai Municipal Commission for the Preservation of Ancient Monuments. Stratigraphically the site falls into four layers: the first and second are surface soil and disturbed deposits respectively, while the third and fourth are cultural layers. Among the finds are pottery, stone and bone artifacts, as well as animal and plant remains. According to stratigraphical evidence and unearthed objects, the site can be divided into two phases. The first phase of remains belongs to the classic Songze culture and is represented by the AⅠ and B Ⅰ subtypes of ding (tripod), A and B types and CI subtype of dou (stemmed vessel) bowl, A type of dou stem, AⅡ subtype of cup and B Ⅰ subtype of jar. Phase Ⅱ is the direct continuation of Phase Ⅰ ; its representatives include the AⅡ and BⅡ subtypes of ding, CⅡ subtype of dou bowl, B type of dou stem, A Ⅳ and AV subtypes of cup base, and BⅡ subtype of jar. In this period, some characteristic features of the Songze culture still existed, and a few distinctive traits of the Liangzhu culture came into being, which suggest the transitional stage from the Songze to the Liangzhu culture.

    The water tank test of marine structures or submarine structures uses a wave maker to generate waves. A typical flap wave maker uses the wave making flap penetrating a water surface whose bottom is fixed on a tank bottom through a hinge, and the top is connected with a rod driven by rotating servomotor for reciprocating motion of the flap. However, this driving gear using a rotating servomotor and a bowl- screw has some defects such as noise caused by bowl rotation, backlash due to wear and limited driving speed. A linear motor with less friction mechanisms was thus applied to the driving gear. The performance test result of the prototype driving gear using a linear motor showed the possibility of the linear driven wave maker. The linear driven wave maker could also achieve low noise and simple mechanism. The sufficient durability and applicability of the linear driven wave maker mechanism were confirmed through strength calculation necessary for improving the prototype wave maker. 1 ref., 5 figs., 2 tabs.

    The article discusses the successful introduction of Derrick Corporation's Stack Sizer technology for removing minus 200 mesh slimes from 6-inch coal hydrocyclone underflow prior to froth flotation or dewatering by screen bowl centrifuges. In 2006, the James River Coal Company selected the Stack Sizer fitted with Derrick 150 micron and 100 micron urethane screen panels for removal of the minus 100 mesh high ash clay fraction from the clean coal spiral product circuits. After this application proved successful, Derrick Corporation introduced new 75 micron urethane screen panels for use on the Stack Sizer. Evaluation of feed slurry to flotation cells and screen bowl centrifuges showed significant amounts of minus 75 micron that could potentially be removed by efficient screening technology. Removal of the minus 75 micron fraction was sought to reduce ash and moisture content of the final clean coal product. Full-scale lab tests confirmed that the Stack Sizer fitted with Derrick 75 micron urethane screen panels consistently reduced the minus 75 micron percentage in coal slurry from 6-inch clean coal hydrocyclone underflow that is approximately 15 to 20% solid by-weight and 30 to 60% minus 75 micron to a clean coal fraction that is approximately 13 to 16% minus 75 micron. As a result total ash is reduced from approximately 36 to 38% in the hydrocyclone underflow to 14 to 16% in the oversize product fraction form the Stack Sizers. 1 fig., 2 tabs., 5 photos.

    Quantifying individual performance in team activity is critical in team selection in international sports. We explore the application of Social Network Analysis (SNA) to rate individuals in an team activity. We choose the game of Cricket as an example. The number runs scored by batsmen and wickets taken by bowlers serves as a natural way of quantifying the performance of a cricketer. Traditionally the batsmen and bowlers are rated on their batting or bowling average respectively. However in a game like cricket it is always important the manner in which one scores the runs or takes a wicket. Scoring runs against a strong bowling line-up or delivering a brilliant performance against a team with strong batting line-up deserves more credit. A player's average is not able to capture this aspect of the game. In this paper we present a refined method to quantify the `quality' of runs scored by a batsman or wickets taken by a bowler. We apply tools of Social Network Analysis (SNA) to judge a cricketer's performance. ...

  10. Scrapheap Challenge

    2004-01-01

    Three British guys at CERN recently took a break from work to try their hand at Scrapheap Challenge. Shown on Channel 4 in the UK, it is a show where two teams must construct a machine for a specific task using only the junk they can scavenge from the scrap yard around them. And they have just 10 hours to build their contraption before it is put to the test. The first round, aired 19 September, pitted a team of three women, from the British Army's Royal Electrical and Mechanical Engineers, against the CERN guys - the Up 'n Atoms: Ali Day, David McFarlane and James Ridewood. Each team, with the help of an appointed expert, had the task of making a giant, 3-metre self-propelled "bowling ball", to roll down a 50 metre bowling alley at skittles 4 metres high. The Up 'n Atoms' contraption featured a small car with a huge wheel on its back. Once up to speed, slamming on the brakes caused the wheel to roll over and take the car with it. On their very last run they managed to take out seven pins. Luckily, though, ...

  11. Characterization of 40 mm dia centrifugal extractor by hydrodynamic and mass transfer experiments. Contributed Paper ED-03

    International Nuclear Information System (INIS)

    Centrifugal extractor is the candid candidate for Fast breeder reprocessing plant due to its low holdup, short contact time and compact size. In this work, 40 mm dia centrifugal extractor was characterized by hydrodynamic and mass transfer experiments. In hydrodynamic experiment, flooding curve was generated by conducting non-mass transfer experiment at different O/A ratio (from 0.06 to 11.5) at constant rotating speed (3000 rpm). Flooding curve indicated varying of throughput from 90 to 60 L/h. Holdup inside the rotating bowl and annular region were measured and liquid residence time in annular region was varying between 5 to 18 seconds depending upon the total throughput. In extraction experiment, mass transfer performance of given CE bowl was studied for different throughputs (from 6 to 60 L/h) at constant speed (3000 rpm) and at constant O/A ratio of one and results shows its overall mass transfer efficiency was nearly 99% for above throughput conditions.

  12. Integrated Information and Prospects for Gliding Mechanism of the Pathogenic Bacterium Mycoplasma pneumoniae

    Science.gov (United States)

    Miyata, Makoto; Hamaguchi, Tasuku

    2016-01-01

    Mycoplasma pneumoniae forms a membrane protrusion at a cell pole and is known to adhere to solid surfaces, including animal cells, and can glide on these surfaces with a speed up to 1 μm per second. Notably, gliding appears to be involved in the infectious process in addition to providing the bacteria with a means of escaping the host's immune systems. However, the genome of M. pneumoniae does not encode any of the known genes found in other bacterial motility systems or any conventional motor proteins that are responsible for eukaryotic motility. Thus, further analysis of the mechanism underlying M. pneumoniae gliding is warranted. The gliding machinery formed as the membrane protrusion can be divided into the surface and internal structures. On the surface, P1 adhesin, a 170 kDa transmembrane protein forms an adhesin complex with other two proteins. The internal structure features a terminal button, paired plates, and a bowl (wheel) complex. In total, the organelle is composed of more than 15 proteins. By integrating the currently available information by genetics, microscopy, and structural analyses, we have suggested a working model for the architecture of the organelle. Furthermore, in this article, we suggest and discuss a possible mechanism of gliding based on the structural model, in which the force generated around the bowl complex transmits through the paired plates, reaching the adhesin complex, resulting in the repeated catch of sialylated oligosaccharides on the host surface by the adhesin complex.

  13. Molecular Gastronomy: Transforming Diets for Dysphagia

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available The purpose of our research is to utilize molecular gastronomy to improve food textures for dysphagia diets, using techniques such as spherification, gelification, and emulsification. It is important for individuals with dysphagia to continue to consume the necessary vitamins and minerals to ensure good health. Molecular gastronomy can be used to enhance pureed diets as more palatable and aesthetically appealing. Medical nutrition therapy for dysphagia calls for foods and beverages to be thickened at prescribed textures and consistencies to prevent choking and aspiration. There is quite a range of unpalatable purees that are currently served to patients, inclusive of baby food and whole meals blenderized together and served in one large bowl. Molecular cuisine allows more variety for many with dysphagia, as food taste is one of few pleasures afforded these patients as a result of their condition and should replace undesirable one bowl meals still served in elder and healthcare facilities. The results of this research suggest that the use of molecular gastronomy in the preparation of pureed foods is favorable and rated highly. The implications of this research can be extended to nursing home facilities, hospitals and long-term care facilities, where patient’s are often on pureed diets for dysphagia.

  14. Exergaming in retirement centres and the integration of media and physical literacies.

    This paper reports on a multi-method analysis of a recently emergent, though still understudied, trend: the use of exercise-themed video games (i.e., 'exergames') in retirement centres. The study in question specifically featured participant observation and interviews with residents and members of staff at retirement centres in Ontario, Canada. Data collection was aimed at understanding how games such as Wii Bowling are being put to use in retirement centre contexts and the implications of such activity. Findings on the one hand suggest that exergames are deemed valuable in the process of promoting both social engagement and physical activity. 'Virtual' bowling can bring people together in communal spaces while also 'getting them up' and active. On the other hand, however, exergaming presents challenges. For retirement centre residents, it engenders health risks while also demanding the deft synchronization of media and physical literacies. For activities coordinators and other members of staff responsible for residents' care, it means they too must stay abreast of the technology sector's latest innovations; they must develop media and physical literacies of their own. These findings are used as a platform for a broader discussion of aging, embodiment, and media in the paper's final section. Against the backdrop of existing conceptualizations of the third age, the use of exergames in retirement centres is deemed conducive not to independence and consumerism fully-fledged, but rather to the manifestation of 'quasi-consumerism' and 'quasi-independence' instead. Third age logic is thus both reinforced and subtly undermined. PMID:26568225

    During the first few days after weaning, pigs often experience BW loss as they adapt to eating solid food. During this time period, they are also known to drink excessively and develop abnormal oral behavior such as belly nosing. The excessive drinking may stem from the piglets' attempt to satiate hunger through gut fill from a familiar ingestive source. Gut fill through water intake may affect the establishment of feeding behavior. Using drinker devices other than the standard nipple drinker may ease the piglets' transition at weaning by facilitating the initiation of feeding and preventing the development of behavioral problems such as excessive drinking and belly nosing. In this experiment, we examined the effect of drinker type on water and food intake, growth rates, and belly nosing in newly weaned piglets. Eighteen pens of 15 piglets each (270 piglets total) were weaned at 18.1 +/- 0.1 d of age and housed in pens containing 1 of 3 drinker devices (standard nipple, push-lever bowl, and float bowl). Piglets' water and feed intake, water use, BW, and behavior were examined on a pen basis through 2 wk after weaning. Piglets with nipple drinkers wasted more water than the other piglets (P wastage can be abated through the use of push-lever drinkers without negative implications for feed intake or growth rates.

    Aeolian processes are a fundamental driver of earth surface dynamics, yet the importance of aeolian processes in a broader geosciences context may be overshadowed by an unbalanced emphasis on fluvial processes. Here we wish to highlight that aeolian and fluvial processes need to be considered in concert relative to total erosion and to potential interactions, that relative dominance and sensitivity to disturbance vary with mean annual precipitation, and that there are important scale-dependencies associated with aeolian-fluvial interactions. We build on previous literature to present relevant conceptual syntheses highlighting these issues. We then highlight the relative investments that have been made in aeolian research on dust emission and management relative to that in fluvial research on sediment production. Literature searches highlight that aeolian processes are greatly understudied relative to fluvial processes when considering total erosion in different environmental settings. Notably, within the USA, aeolian research was triggered by the Dust Bowl catastrophe of the 1930s, but the resultant research agencies have shifted to almost completely focusing on fluvial processes, based on number of remaining research stations and on monetary investments in control measures. However, numerous research issues associated with intensification of land use and climate change impacts require a rapid ramping up in aeolian research that improves information about aeolian processes relative to fluvial processes, which could herald a post-Dust Bowl Phoenix phase in which aeolian processes are recognized as broadly critical to geo- and environmental sciences.

    . By characterizing the energy required to initiate several different materials, more effective formulations can be designed using the better performing materials. Presented here are the results of laser initiation tests on a variety of compositions, principally combinations of PETN, DAATO{sub 3.5}, HMX, Ag{sub 2}BTA (silver bistetrazolamine), CuBTA, BNCP (bis-5-nitrotetrazolato tetraamine cobalt perchloriate), nm Ag, and a variety of MICs (metastable intermolecular compounds). Also presented are the conclusions as to which formulations are most suitable for optically initiated systems.

    Conformationally rigidified tetraCMPO derivatives have been prepared from calix[4]arene bis(crown ether) 4a in which adjacent oxygens are bridged at the narrow rim by two diethylene glycol links. Acylation of the tetraamine 4c with the CMPO-active ester 5b gave the tetraphosphine oxide 6a, while the tetraphosphinate 6b and the tetraphosphonate 6c were obtained by Arbuzov reaction of tetrabromoacetamido derivative 7 with PhP(OEt)2 or P(OEt)3. The extraction ability of these CMPO derivatives was checked for selected lanthanides and actinides and compared with the analogous compounds 1b, 10b and 10d derived from calix[4]arene tetrapentyl ether. All rigidified bis(crown ether) ligands are more effective extractants than their pentyl ether counterparts and require only 1/10 of the concentration (cL= 10 4M) to obtain the same distribution coefficients, while with CMPO itself a 2,000-fold concentration is necessary. This could be a consequence of a better preorganisation of the ligating functions owing to the rigidity which on the other hand did not change the observed selectivity for americium (DAm/DEu=9-19) and for light lanthanides over heavy ones. NMR relaxivity titration curves show that the complex of Gd3+ with ligand 6a is highly oligomerised in anhydrous acetonitrile over a large range of ligand:metal concentration ratios. Nuclear magnetic relaxation dispersion (NMRD) profiles also showed that large oligomers were formed, and their mean tumbling times were deduced from the Solomon-Bloembergen-Morgan equations. The NMR spectra of dia- and paramagnetic lanthanide complexes with 6a agreed with the presence of two conformers with an elongated calix[4]arene skeleton in which the distances between opposite methylene groups are different. Contrary to what was observed with ligand 2a, the addition of nitrate ions does not labilize the metal complexes, presumably because of the rigidification effect of the ether bridges. Single-crystal X-ray structures were obtained for

  19. Development of 99mTc labelled somatostatin analogues with high affinity for somatostatin receptors

    International Nuclear Information System (INIS)

    A recent development in oncology involves the use of metabolically stabilized peptide hormone analogues labelled with metallic radionuclides for the diagnosis or therapy of malignant disease. This approach was successfully applied for the first time in the visualization of somatostatin positive tumours and their metastases with 111In DTPA-octreotide. In an effort to obtain a 99mTc somatostatin receptor affine radioligand we describe herein the synthesis, radiochemistry and preliminary biological evaluation of two novel 99mTc labelled somatostatin analogues, N4-TOC and N4-RC-160. In these compounds a tetraamine bifunctional unit was covalently attached to the N-terminal (D)Phe1 of the peptide chain using Boc-protection strategies. The peptide conjugates were purified by high performance liquid chromatography (HPLC) and characterized by UV/Vis and ES-MS spectroscopies. As revealed by HPLC, 99mTc labelling was quantitative under mild conditions, leading to a single 99mTc species in high specific activities. Affinity of 99mTc N4-TOC for the somatostatin receptor, as determined by in vitro binding assays in rat brain cortex membranes, was found unaffected by the presence of the bulky metal chelate. The binding properties of 99mTc N4-RC-160 could not be determined by this assay due to an extremely high non-specific binding of this radioligand, and will be shortly investigated by other methods. Tissue distribution in healthy mice revealed that 99mTc N4-TOC is clearing mainly through the kidneys and the urinary tract whereas 99mTc N4-RC-160 shows a high accumulation in the liver as a result of its lipophilicity. Analysis of urine samples by HPLC showed that 99mTc N4-TOC is excreted integer from the body of mice, while 99mTc N4-RC-160 is totally transformed to an unidentified hydrophilic metabolite in vivo. The location of this metabolism is currently investigated. In vivo blocking experiments using animals pre-treated with 50 μg octreotide prior to the injection of the

    Demobesin 1 is a potent new GRP-R-selective bombesin (BN) analogue containing an open chain tetraamine chelator for stable technetium-99m binding. Following a convenient labelling protocol, the radiopeptide, [{sup 99m}Tc]Demobesin 1, formed in nearly quantitative yields and with high specific activities. Both unlabelled and labelled peptide demonstrated high-affinity binding in membrane preparations of the human androgen-independent prostate adenocarcinoma PC-3 cell line. The IC{sub 50} values determined for Demobesin 1 and [Tyr{sup 4}]BN were 0.70{+-}0.08 nM and 1.5{+-}0.20 nM, respectively, while the K{sub d} defined for [{sup 99m}Tc/{sup 99g}Tc]Demobesin 1 was 0.67{+-}0.10 nM. [{sup 99m}Tc]Demobesin 1 was rather stable in murine plasma, whereas it degraded rapidly in kidney and liver homogenates. After injection in healthy Swiss albino mice, [{sup 99m}Tc]Demobesin 1 accumulated very efficiently in the target organs (pancreas, intestinal tract) via a GRP-R-mediated process, as shown by in vivo receptor blocking experiments. An equally high and GRP-R-mediated uptake was exhibited by [{sup 99m}Tc]Demobesin 1 after injection in PC-3 tumour-bearing athymic mice. The initial high radioligand uptake of 16.2{+-}3.1%ID/g in the PC-3 xenografts at 1 h p.i. remained at a similar level (15.61{+-}1.19%ID/g) at 4 h p.i. Even after 24 h p.i., when the radioactivity had cleared from all other tissues, a value of 5.24{+-}0.67%ID/g was still observed in the tumour. The high and prolonged localization of [{sup 99m}Tc]Demobesin 1 at the tumour site and its rapid background clearance are very promising qualities for GRP-R-targeted tumour imaging in man. (orig.)
