    Attention is drawn to a particularly dangerous party activity. Balloons filled with lighter gas so as to float are used for party decorations. A case of hand burn caused by accidentally lighting such a balloon with a cigarette is reported. The method is strongly advised against, it is a much better idea to use helium for such purposes.

    This book presents a collection of cartoons that focus on the lighter side of teaching. In a tongue-in-cheek introduction, the book asserts that one achievable goal which should have been included in the 1994 Educate America Act is that all teachers will start each school day by reading one funny cartoon and having a good chuckle before they go to…

  15. Dark Matter Coannihilation with a Lighter Species

    NASA Astrophysics Data System (ADS)

    Berlin, Asher

    2017-09-01

    We propose a new thermal freeze-out mechanism for ultraheavy dark matter. Dark matter coannihilates with a lighter unstable species that is nearby in mass, leading to an annihilation rate that is exponentially enhanced relative to standard weakly interactive massive particles. This scenario destabilizes any potential dark matter candidate. In order to remain consistent with astrophysical observations, our proposal necessitates very long-lived states, motivating striking phenomenology associated with the late decays of ultraheavy dark matter, potentially as massive as the scale of grand unified theories, MGUT˜1016 GeV .

  1. Bounds for lighter Higgses in extensions of the Standard Model

    NASA Astrophysics Data System (ADS)

    Deandrea, Aldo

    2017-07-01

    Higgs bosons lighter than the 125 GeV one can be present in extensions of the Standard Model and exclusion or discovery of such a possibility allows to improve our knowledge of the Higgs sector. I consider Two Higgs Doublet Models, which are the minimal scalar structure of a large number of models, in order to explore the possibility of constraining a neutral scalar particle lighter than the 125 GeV Higgs boson. Such a lighter particle is not yet completely excluded by present data. I show that some new constraints can be obtained at the LHC for these light particles.

    We investigate solitary waves in a multicomponent plasma of positively and negatively charged lighter and heavier ions and electrons of solar and cometary origin; the electron components are modeled by kappa distributions. The solitary wave solution of the Zakharov-Kuznetsov (ZK) equation is plotted for parameters of comet Halley; physical variables like densities and temperatures of negatively charged lighter ions significantly affect the width and amplitude of the solitary waves.

  8. Advanced Technology for Lighter and More Cost Effective Space Vehicles

    NASA Technical Reports Server (NTRS)

    1998-01-01

    Engineers at Marshall Space Flight Center (MSFC) in Huntsville, Alabama, are working with industry partners to develop a new generation of more cost-efficient space vehicles. Lightweight fuel tanks and components under development will be the critical elements in tomorrow's reusable launch vehicles and will tremendously curb the costs of getting to space. In this photo, Tom DeLay, a materials processes engineer for MSFC, uses a new graphite epoxy technology to create lightweight cryogenic fuel lines for futuristic reusable launch vehicles. He is wrapping a water-soluble mandrel, or mold, with a graphite fabric coated with an epoxy resin. Once wrapped, the pipe will be vacuum-bagged and autoclave-cured. The disposable mold will be removed to reveal a thin-walled fuel line. In addition to being much lighter and stronger than metal, this material won't expand or contract as much in the extreme temperatures encountered by launch vehicles.

  11. Estimation of emissions from charcoal lighter fluid and review of alternatives. Final report

    SciTech Connect

    Campbell, D.L.; Stockton, M.B.

    1990-01-01

    The report gives results of an evaluation of emissions of volatile organic compounds (VOCs) from charcoal lighter fluid, a consumer product consisting entirely of volatile constituents. An estimated 46,250 tons (42,000 Mg) of charcoal lighter fluid is used in the U.S. each year. VOCs contribute to the formation of ozone; therefore, the ozone nonattainment issue has focused attention on VOCs emitted from many sources. VOCs are emitted when charcoal lighter fluid is used, but these emissions are difficult to quantify. Evaporative VOC losses occur from the lighter fluid prior to ignition, and combustion VOC losses occur from burning lighter-fluid-soaked charcoal briquettes. This study evaluates tests conducted to date on charcoal lighter fluid emissions. The information is most complete for evaporative VOC losses. The estimates vary greatly, however, based on the length of time between application of the lighter fluid and ignition. The limited tests conducted to date have not distinguished lighter fluid from charcoal-briquette combustion emissions.

    2017-01-01

    Voluntary inhalation/abuse of volatile substances is an important public health problem which especially affects adolescent and young populations worldwide and may be encountered in all socioeconomic and cultural levels. Lighter gas abuse-related death is still an important health problem in Turkey. In this study, 25,265 case files and final reports submitted to the Institute of Forensic Medicine of the First Specialization Board between January 2011 and December 2015 were evaluated retrospectively. In 56 of these cases, lighter gas inhalation (n-butane, propane, isobutane) was recorded as the cause of death. All subjects were male with a mean age of 16.8years. According to eyewitness and crime scene investigation reports, in 48 (85.7%) of the cases, a lighter refill container was found at the scene. It was determined that 21.4% of the cases used a plastic bag to increase the effects of lighter gas and 76.8% inhaled the lighter gas via their mouth and nose. The toxicological analysis of the samples taken while hospitalized showed no lighter refill components (n-butane, propane, isobutane) in 66% of the cases, n-butane in 32.1% of the cases, and n-butane+propane+isobutane in 1.9% of the cases. The importance of lighter gas inhalation-related deaths in Turkey has been increasing. Strict measures against the abuse of these very dangerous substances should be undertaken by the mutual efforts of medical specialists and legislators. Copyright © 2016 Elsevier Ireland Ltd.

  2. Study of the effectiveness of the US safety standard for child resistant cigarette lighters

    PubMed Central

    Smith, L; Greene, M; Singh, H

    2002-01-01

    Objective: The purpose of this research is to evaluate the effectiveness of the US Consumer Product Safety Commission's (CPSC) Safety Standard for Cigarette Lighters, which requires that disposable cigarette lighters be resistant to operation by children younger than age 5. Methods: Fire data on children playing with lighters were solicited from selected US fire departments for incidents occurring from 1997–99, to identify the proportion of such fires caused by children younger than age 5 playing with cigarette lighters. These data were compared with similar data from 1985–87. An odds ratio was used to determine if there was a significant decrease in cigarette lighter fires caused by children younger than age 5 compared to children ages 5 and older. To estimate fires that would have occurred without the standard, the odds ratio, adjusted for population, was applied to 1998 national estimates of fires occurring. National estimates of 1998 fire losses were based on data from the National Fire Incident Reporting System and the National Fire Protection Association to which the 1997–99 age and lighter type distributions were applied. The difference between the fire losses that would have occurred and those that did occur represented fire losses prevented. Results: In the post-standard study, 48% of the cigarette lighter fires were started by children younger than age 5, compared with 71% in the pre-standard study. The odds ratio of 0.42 was statistically significant (p<0.01). This represented a 58% reduction in fires caused by the younger age group compared to the older age group. When applied to national fire loss data, an estimated 3300 fires, 100 deaths, 660 injuries, and $52.5 million in property loss were prevented by the standard in 1998, totaling $566.8 million in 1998 societal savings. Conclusions: The CPSC standard requiring child resistant cigarette lighters has reduced fire deaths, injuries, and property loss caused by children playing with cigarette

  3. An approach to market analysis for lighter than air transportation of freight

    NASA Technical Reports Server (NTRS)

    Roberts, P. O.; Marcus, H. S.; Pollock, J. H.

    1975-01-01

    An approach is presented to marketing analysis for lighter than air vehicles in a commercial freight market. After a discussion of key characteristics of supply and demand factors, a three-phase approach to marketing analysis is described. The existing transportation systems are quantitatively defined and possible roles for lighter than air vehicles within this framework are postulated. The marketing analysis views the situation from the perspective of both the shipper and the carrier. A demand for freight service is assumed and the resulting supply characteristics are determined. Then, these supply characteristics are used to establish the demand for competing modes. The process is then iterated to arrive at the market solution.

  4. Search for a lighter Higgs boson in Two Higgs Doublet Models

    We consider present constraints on Two Higgs Doublet Models, both from the LHC at Run 1 and from other sources in order to explore the possibility of constraining a neutral scalar or pseudo-scalar particle lighter than the 125 GeV Higgs boson. Such a lighter particle is not yet completely excluded by present data. We show with a simplified analysis that some new constraints could be obtained at the LHC if such a search is performed by the experimental collaborations, which we therefore encourage to continue carrying out light diphoton resonance searches at √{s}=13 TeV in the context of Two Higgs Doublet Models.

  9. Impact of darker, intermediate and lighter phenotypes of body melanization on desiccation resistance in Drosophila melanogaster.

    PubMed

    Parkash, Ravi; Rajpurohit, Subhash; Ramniwas, Seema

    2009-01-01

    A possible link between melanization and desiccation resistance can be inferred if within population differences in melanization find significant correlations with desiccation resistance and its mechanistic basis i.e. rate of water loss/hr. Accordingly, darker, intermediate and lighter phenotypes of body melanization were analyzed in wild and laboratory reared Drosophila melanogaster L. (Diptera: Clyclorrapha) populations from highland and lowland sites located in close proximity at five different latitudinal locations (11.15 degrees N to 31.06 degrees N) within the Indian subcontinent. In large population samples, occurrence of significant within population variability made it possible to assort non-overlapping phenotypes of body coloration (i.e. lighter (< 25%), intermediate (30 to 40%) and darker (> 45%)) for all the populations which were further investigated for desiccation resistance and rate of water loss/hr. Significantly, higher desiccation resistance but much reduced rate of water loss/hr were observed in darker and intermediate phenotypes in all the populations. By contrast, lighter phenotypes exhibited lower desiccation tolerance but higher rate of water loss/hr. A regression analysis between traits provided similar slope values for wild and laboratory populations. For all three physiological traits, predicted trait values from multiple regression analysis as a simultaneous function of annual average temperature and relative humidity, matched the observed values. We infer that parallel changes in melanization and desiccation resistance may result from decreasing annual average temperature and relative humidity along increasing latitude as well as altitude on the Indian subcontinent.

    We have studied the combined effect of the pressure anisotropies of lighter and heavier ions of opposite polarities on solitary waves in a plasma composed of these ions as well as kappa described electrons of solar and cometary origin. Using the theory of Chew, Goldberger, and Low (the CGL theory), the anisotropies of all three ions have been included in the derivation of the Zakharov-Kuznetsov equation. The effects of various combinations of pressure anisotropies of both lighter as well as heavier ions of opposite polarities have been considered. From the figures, plotted for parameters observed at comet Halley, it is seen that different properties of the solitary wave such as width and amplitude, as well as dispersion and nonlinear coefficients, are profoundly affected by the anisotropies of the ions. Also, the pressure anisotropy of the lighter ions determines the polarity of the solitary waves: the plasma supports compressive (rarefactive) solitary waves when the lighter ions are pressure isotropic (anisotropic).

    Static dipole polarizabilities of element 119 and its singly charged cation are calculated, along with those of its lighter homologs, Cs and Fr. Relativity is treated within the 4-component Dirac-Coulomb formalism and electron correlation is included by the single reference coupled cluster approach with single, double, and perturbative triple excitations (CCSD(T)). Very good agreement with available experimental values is obtained for Cs, lending credence to the predictions for Fr and element 119. The atomic properties in group-1 are largely determined by the valence ns orbital, which experiences relativistic stabilization and contraction in the heavier elements. As a result, element 119 is predicted to have a relatively low polarizability (169.7 a.u.), comparable to that of Na. The adsorption enthalpy of element 119 on Teflon, which is important for possible future experimental studies of this element, is estimated as 17.6 kJ/mol, the lowest among the atoms considered here.

    The present study evaluated the effect of a smaller, lighter ball on kicking speed and technical-tactical and physical match performance in high-level adult female footballers. In the laboratory test setting, the peak ball velocity was 6% higher with the new ball (NB) than the standard ball (SB) (26.5±0.5 vs. 25.1±0.5 m·s(-1), p<0.05). However, during match-play, no differences were observed in mean heart rate (87±5 vs. 87±5%HRmax; p>0.05), blood lactate (90 min: 4.7±1.7 and 4.0±1.7 mmol·l(-1); p>0.05), total distance covered (10.6±0.9 and 10.4±0.8 km; p>0.05), intense running (>16 km/h) (2.08±0.42 and 1.94±0.38 km; p>0.05) and match-induced decrement in Yo-Yo IR1 performance (28 vs. 31%, respectively, p<0.05) using NB compared to SB. Likewise, no difference was observed in the number of short, medium-range or long passes during matches played with the 2 ball types, and there was no difference in passing success rate (NB: 68±1% and SB: 68±1%, p>0.05). In conclusion, high-level adult female footballers had a higher kicking speed when using a smaller, lighter ball, but no differences were observed during match-play with the 2 ball types in respect of technical-tactical and physical match performance. The physical loading was high for the players when playing with both ball types. © Georg Thieme Verlag KG Stuttgart · New York.

    This report provides a historical survey and assessment of the state of the art in the modeling and application of active control to aircraft encountering atmospheric disturbances in flight. Particular emphasis is placed on applications of active control technologies that enable weight reduction in aircraft by mitigating the effects of atmospheric disturbances. Based on what has been learned to date, recommendations are made for addressing gust alleviation on as the trend for more structurally efficient aircraft yields both lighter and more flexible aircraft. These lighter more flexible aircraft face two significant challenges reduced separation between rigid body and flexible modes, and increased sensitivity to gust encounters due to increased wing loading and improved lift to drag ratios. The primary audience of this paper is engineering professionals new to the area of gust load alleviation and interested in tackling the multifaceted challenges that lie ahead for lighter-weight aircraft.

    Flotation of a denser liquid drop on lighter liquid has been explained earlier via the Neumann triangle. We demonstrate the flotation of a denser liquid (water) drop on a lighter liquid in a pair that does not satisfy the Neumann triangle. We attribute this newly studied phenomenon to the role of line tension τ which prevents the water droplet from complete engulfment. A simple model is used to explain the underlying physics and to obtain critical line tension value for stable flotation. We establish line tension values for different liquids with water and show possible heterogeneous nucleation that contributes toward the variance of line tension values.

    Our study examined whether the introduction of a smaller and lighter basketball (no. 6) affected the accuracy of female basketball players’ shots at the basket. The International Basketball Federation (FIBA) introduced a size 6 ball in the 2004/2005 season to improve the efficiency and accuracy of technical elements, primarily shots at the basket. The sample for this study included 573 European female basketball players who were members of national teams that had qualified for the senior women’s European championships in 2001, 2003, 2005 and 2007. A size 7 (larger and heavier) basketball was used by 286 players in 1,870 matches, and a size 6 basketball was used by 287 players in 1,966 matches. The players were categorised into three playing positions: guards, forwards and centres. The results revealed that statistically significant changes by year occurred only in terms of the percentage of successful free throws. With the size 6 basketball, this percentage decreased. Statistically significant differences between the playing positions were observed in terms of the percentage of field goals worth three points (between guards and forwards) and two points (between guards and centres). The results show that the introduction of the size 6 basketball did not lead to improvement in shooting accuracy (the opposite was found for free throws), although the number of three-point shots increased.

    Today's society places an extremely high price on the value of human life and injury. Whenever possible, police and paramilitary actions are always directed towards saving as many lives as possible, whether it is the officer, perpetrator, or innocent civilians. Recently, the advent of robotic systems has enable law enforcement agencies to perform many of the most dangerous aspects of their jobs from relative safety. This is especially true to bomb disposal units but it is also gaining acceptance in other areas. An area where small, remotely operated machines may prove effective is in local aerial surveillance. Currently, the only aerial surveillance assets generally available to law enforcement agencies are costly helicopters. Unfortunately, most of the recently developed unmanned air vehicles (UAVs) are directed towards military applications and have limited civilian use. Systems Planning and Analysis, Inc. (SPA) has conceived and performed a preliminary analysis of a low-cost, inflatable, lighter- than-air surveillance system that may be used in a number of military and law enforcement surveillance situations. The preliminary analysis includes the concept definition, a detailed trade study to determine the optimal configuration of the surveillance system, high-pressure inflation tests, and a control analysis. This paper will provide the details in these areas of the design and provide an insight into the feasibility of such a system.

    The Western Australian (WA) 'LiveLighter' (LL) mass media campaign ran during June-August and September-October 2012. The principal campaign ad graphically depicts visceral fat of an overweight individual ('why' change message), whereas supporting ads demonstrate simple changes to increase activity and eat healthier ('how' to change message). Cross-sectional surveys among population samples aged 25-49 were undertaken pre-campaign (N= 2012) and following the two media waves (N= 2005 and N= 2009) in the intervention (WA) and comparison state (Victoria) to estimate the population impact of LL. Campaign awareness was 54% after the first media wave and overweight adults were more likely to recall LL and perceive it as personally relevant. Recall was also higher among parents, but equal between socio-economic groups. The 'why' message about health-harms of overweight rated higher than 'how' messages about lifestyle change, on perceived message effectiveness which is predictive of health-related intention and behaviour change. State-by-time interactions showed population-level increases in self-referent thoughts about the health-harms of overweight (P < 0.05) and physical activity intentions (P < 0.05). Endorsement of stereotypes of overweight individuals did not increase after LL aired. LL was associated with some population-level improvements in proximal and intermediate markers of campaign impact. However, sustained campaign activity will be needed to impact behaviour.

    A very large area (7.5 mm(2)) laser-driven x-ray backlighter, termed the Big Area BackLighter (BABL) has been developed for the National Ignition Facility (NIF) to support high energy density experiments. The BABL provides an alternative to Pinhole-Apertured point-projection Backlighting (PABL) for a large field of view. This bypasses the challenges for PABL in the equatorial plane of the NIF target chamber where space is limited because of the unconverted laser light that threatens the diagnostic aperture, the backlighter foil, and the pinhole substrate. A transmission experiment using 132 kJ of NIF laser energy at a maximum intensity of 8.52 × 10(14) W/cm(2) illuminating the BABL demonstrated good conversion efficiency of >3.5% into K-shell emission producing ~4.6 kJ of high energy x rays, while yielding high contrast images with a highly uniform background that agree well with 2D simulated spectra and spatial profiles.

  11. Larger, Lighter Space Telescopes by Implementing In-Space Manufacturing Concepts

    2007-01-01

    There is a continuous demand for larger, lighter, and higher quality telescopes from both the astronomical and global surveillance communities one looking up and the other down. Enabling technologies must be developed and implemented that will allow this goal to be financially and technically feasible. The optical systems needed far high spatial resolution surveillance and astronomical applications require large optical, apertures with mention of future systems up to 150 meter in diameter. With traditional optical manufacturing technologies, large optical aperture means high mass and long fabrication lead times with associated high costs. Completely new approaches to optical fabrication must be developed to enable the fabrication of such optical systems. The cost and lead time associated with the fabrication of lightweight, high quality optical systems limits the feasible size of the optics. A primary factor in the launch cost of space optical systems is volume and mass. To minimize the mass of the high quality optics, optical fabricators implement materials with high specific stiffness and use honeycomb, or other structural minimization patterns, to support the optical surface; however, the structure must still be designed to survive launch loads. This sigmficantly adds to the fabrication difficulty and dramatically increases launch costs. One approach to minimizing launch volume and negating the need for the design to survive launch loads is to send the manufacturing facility and raw materials into space and perform the fabrication in-situ. We, are currently performing feasibility studies of initial concepts for inspace manufacturing of optical systems. By utilizing the micro-gravity and vacuum environment of space while eliminating the constraints defined by high launch forces and limited volume of the launch vehicle, the development of large, high quality glass membrane mirrors may be feasible. Several concepts were investigated to address the manufacturing of

  12. Lighter-Than-Air Blimps As a Testbed For River Remote Sensing Techniques

    NASA Astrophysics Data System (ADS)

    Fonstad, M. A.

    2010-12-01

    River science has seen a methodological revolution during the past decade as new platforms, sensors, and processing algorithms have allowed the remote collection of river data with ever-increasing ease, accuracy, precision, and extent. Recently, hand-held, low cost lighter-than-air blimps have been suggested as an important platform for river remote sensing, particularly when high-resolution and low-cost imaging is required. Because blimps are small, inexpensive, and relatively simple to operate in the field, they allow rapid river remote sensing trials, particularly over shorter river reaches. Unlike most airborne or satellite approaches, hand-held blimps can also be used to do very rapid repeat imaging. Field experiments show that such hand-held platforms are not as stable as most airborne and satellite platforms, and they have far reduced lift, allowing only very small and simple camera systems. They are also susceptible to become entangled in near-channel trees, and almost always have the problem of inclusion of the operator somewhere in resulting image. These issues notwithstanding, the simple adjustment of blimp tether length can easily allow adjustment of ground resolution to extremely high levels, and programmable cameras can allow versatility in automatic camera shutter intervals, shutter speeds, and other image constraints. We utilize low-altitude helikite platforms to test the potential for remote sensing (a) well geometrically-controlled measurements of water surface configuration, (b) submerged and near-channel sediment sizes, (c) water depth, and (d) surface velocity. The velocity imaging techniques include the use of natural and artificial particle image velocimetry (PIV) features, with velocity extracted using either the principles of motion blur or from sequential images. In addition, we use these low-cost, mobile platforms to test the brightness and color effects of shadows cast upon the water surface, and use these results to suggest potential

    Inhalatomania with volatile organic compounds is a still present phenomenon among Polish young adolescents. Conscious, voluntary exposition on such substances may result in serious health consequences, including sudden death in the course of acute intoxication. In this paper, atypical case of death of 16-year-old teenager as a result of complications of physically forced inhalation of gas for lighters is presented. According to testimonies of witnesses, the container was placed in the mouth of victim and the gas was introduced directly to his throat. Autopsy revealed small damage of tooth with corresponding bruising of lower lip; brain and lung oedma; single bruisings in the upper respiratory tract and subpleural. Chemical-toxicological analysis of blood, brain and lung samples taken during autopsy revealed in all of them the presence of n-butan--a component of gas for lighters (the greatest in brain and lung tissues). Additionally, in blood the presence of carboxyhemoglobin (COHb) in concentration 7% was confirmed. Based on the results of analyses, acute intoxication with n-butan was estimated as a cause of death; however the key role played the information obtained during the investigation. This case shows, that deaths resulting from gas for lighters inhalation may be a consequence of forced exposition--against victim's will. So medical staff should always check, if on the body of patient there are any signs of physical constraint (the presence of bruisings in the area of viscerocranium and oral cavity, teeth damages, etc.).

  14. CNT reinforced epoxy foamed and electrospun nano-fiber interlayer systems for manufacturing lighter and stronger featherweight(TM) composites

    NASA Astrophysics Data System (ADS)

    Drakonakis, Vasileios M.

    Multiple works have been performed in improving carbon fiber reinforced polymer (CFRP) composites especially in terms of strength so delamination, which is the major defect in laminated composites, is prevented. Nevertheless, there is not much focus on improving conventional CFRP systems in terms of weight especially when these are used in primary structures. This work questions whether lighter and at the same time stronger CFRP composites can be manufactured in order to replace conventional CFRP systems in major applications. Under this perspective, this study demonstrates that inducing controlled porosity may offer a systemic approach for manufacturing light weight carbon fiber reinforced polymer (CFRP) matrix composites. Additionally, towards this scope, this work has focused on analyzing and describing the related matrix systems utilizing mostly classic viscoelastic theory. An in-depth characterization of the thermosetting matrix systems viscoelasticity kinetics as well as of the impregnation process towards its improvement in terms of lower cost is explored. Overall, this work makes an effort to establish the fundamentals for creating the next generation of light weight structural composites, the featherweight composites, by introducing porosity through several controlled reinforcements in a systemic and reproducible manner at the macro- micro- and nano- scales in the interlayer. By extensively describing the matrix system and the manufacturing processes and focusing on analytically testing the interlayer reinforcement systems, it is expected that featherweight CFRP will achieve lighter weight and at the same time higher mechanical properties.

  15. Lighter and heavier initial loads yield similar gains in strength when employing a progressive wave loading scheme

    PubMed Central

    Wood, PP; Goodwin, JE

    2016-01-01

    Progressive wave loading strategies are common within strength and conditioning practice. The purpose of this study was to contribute to the understanding of this strategy by evaluating the effectiveness of 2 wave loading bench press training programmes that differed only in the initial load that was used to start the first wave. Thirty-four resistance-trained men were divided into 2 groups and performed 2 training sessions each week for 20 weeks. One session consisted of 6 sets of 2 repetitions, while the other consisted of 5 sets of 5 repetitions. The load used was incremented by 2.5% of one repetition maximum (1RM) each week until the subject could no longer complete the programmed repetitions. At this point, the load was decreased, and then started to ascend again. The initial loads for the 2 sessions were 87.5% and 80% 1RM respectively for the heavier group, and for the lighter group were 82.5% and 75% 1RM. The subjects experienced a significant improvement in their bench press performance (higher load group: pre test = 106.5 kg ± 14.6, post test = 112.2 kg ± 12.4, p ≤ 0.05; lower load group: pre test = 105.7 kg ± 14.1, post test = 114.3 kg ± 11.0, p ≤ 0.05), but there was no difference in the magnitude of the improvment between the two groups. These results tend to support the common practical recommendation to start with a lighter load when employing a progressive wave loading strategy, as such a strategy yields similar improvements in performance with a lower level of exertion in training.

    Lighter Than Air vehicles are generally defined or categorized by the shape of the balloon, payload capacity and operational flight regime. Two balloon systems that are classed as being in opposite categories are described. One is a cable guided, helium filled, short haul, heavy load transport Lighter Than Air system with a natural shaped envelope. The other is a manned, aerodynamic shaped airship which utilizes hot air as the buoyancy medium and is in the light payload class. While the airship is in the design/fabrication phase with flight tests scheduled for the latter part of 1974, the transport balloon system has been operational for some eight years.

    The uses of lighter-than-air vehicles are examined in the present day transportation environment. Conventional dirigibles were found to indicate an undesirable economic risk due to their low speeds and to uncertainties concerning their operational use. Semi-buoyant hybrid vehicles are suggested as an alternative which does not have many of the inferior characteristics of conventional dirigibles. Economic and performance estimates for hybrid vehicles indicate that they are competitive with other transportation systems in many applications, and unique in their ability to perform some highly desirable emergency missions.

  1. Development of a dispersive liquid-liquid microextraction method using a lighter-than-water ionic liquid for the analysis of polycyclic aromatic hydrocarbons in water.

    A dispersive liquid-liquid microextraction method using a lighter-than-water phosphonium-based ionic liquid for the extraction of 16 polycyclic aromatic hydrocarbons from water samples has been developed. The extracted compounds were analyzed by liquid chromatography coupled to fluorescence/diode array detectors. The effects of several experimental parameters on the extraction efficiency, such as type and volume of ionic liquid and disperser solvent, type and concentration of salt in the aqueous phase and extraction time, were investigated and optimized. Three phosphonium-based ionic liquids were assayed, obtaining larger extraction efficiencies when trihexyl-(tetradecyl)phosphonium bromide was used. The optimized methodology requires a few microliters of a lighter-than-water phosphonium-based ionic liquid, which allows an easy separation of the extraction solvent phase. The obtained limits of detection were between 0.02 and 0.56 μg/L, enrichment factors between 109 and 228, recoveries between 60 and 108%, trueness between 0.4 and 9.9% and reproducibility values between 3 and 12% were obtained. These figures of merit combined with the simplicity, rapidity and low cost of the analytical methodology indicate that this is a viable and convenient alternative to the methods reported in the literature. The developed method was used to analyze polycyclic aromatic hydrocarbons in river water samples.

  4. The lighter side of BDNF

    Brain-derived neurotrophic factor (BDNF) mediates energy metabolism and feeding behavior. As a neurotrophin, BDNF promotes neuronal differentiation, survival during early development, adult neurogenesis, and neural plasticity; thus, there is the potential that BDNF could modify circuits important to eating behavior and energy expenditure. The possibility that “faulty” circuits could be remodeled by BDNF is an exciting concept for new therapies for obesity and eating disorders. In the hypothalamus, BDNF and its receptor, tropomyosin-related kinase B (TrkB), are extensively expressed in areas associated with feeding and metabolism. Hypothalamic BDNF and TrkB appear to inhibit food intake and increase energy expenditure, leading to negative energy balance. In the hippocampus, the involvement of BDNF in neural plasticity and neurogenesis is important to learning and memory, but less is known about how BDNF participates in energy homeostasis. We review current research about BDNF in specific brain locations related to energy balance, environmental, and behavioral influences on BDNF expression and the possibility that BDNF may influence energy homeostasis via its role in neurogenesis and neural plasticity.

  8. IS THE SUN LIGHTER THAN THE EARTH? ISOTOPIC CO IN THE PHOTOSPHERE, VIEWED THROUGH THE LENS OF THREE-DIMENSIONAL SPECTRUM SYNTHESIS

    We consider the formation of solar infrared (2-6 {mu}m) rovibrational bands of carbon monoxide (CO) in CO5BOLD 3D convection models, with the aim of refining abundances of the heavy isotopes of carbon ({sup 13}C) and oxygen ({sup 18}O, {sup 17}O), to compare with direct capture measurements of solar wind light ions by the Genesis Discovery Mission. We find that previous, mainly 1D, analyses were systematically biased toward lower isotopic ratios (e.g., R {sub 23} {identical_to} {sup 12}C/{sup 13}C), suggesting an isotopically 'heavy' Sun contrary to accepted fractionation processes that were thought to have operated in the primitive solar nebula. The new 3D ratios for {sup 13}C and {sup 18}O are R {sub 23} = 91.4 {+-} 1.3 (R {sub Circled-Plus} = 89.2) and R {sub 68} = 511 {+-} 10 (R {sub Circled-Plus} = 499), where the uncertainties are 1{sigma} and 'optimistic'. We also obtained R {sub 67} = 2738 {+-} 118 (R {sub Circled-Plus} = 2632), but we caution that the observed {sup 12}C{sup 17}O features are extremely weak. The new solar ratios for the oxygen isotopes fall between the terrestrial values and those reported by Genesis (R {sub 68} = 530, R {sub 67} = 2798), although including both within 2{sigma} error flags, and go in the direction favoring recent theories for the oxygen isotope composition of Ca-Al inclusions in primitive meteorites. While not a major focus of this work, we derive an oxygen abundance, {epsilon}{sub O} {approx} 603 {+-} 9 ppm (relative to hydrogen; log {epsilon} {approx} 8.78 on the H = 12 scale). The fact that the Sun is likely lighter than the Earth, isotopically speaking, removes the necessity of invoking exotic fractionation processes during the early construction of the inner solar system.

    Feasibility study to compare the effectiveness of 2 brace design and fabrication methods for treatment of adolescent idiopathic scoliosis: a standard plaster-cast method and a computational method combining computer-aided design and fabrication and finite element simulation. To improve brace design using a new brace design method. Initial in-brace correction and patient's compliance to treatment are important factors for brace efficiency. Negative cosmetic appearance and functional discomfort resulting from pressure points, humidity, and restriction of movement can cause poor compliance with the prescribed wearing schedule. A total of 15 consecutive patients with brace prescription were recruited. Two braces were designed and fabricated for each patient: a standard thoracolumbo-sacral orthosis brace fabricated using plaster-cast method and an improved brace for comfort (NewBrace) fabricated using a computational method combining computer-aided design and fabrication software (Rodin4D) and a simulation platform. Three-dimensional reconstructions of the torso and the trunk skeleton were used to create a personalized finite element model, which was used for brace design and predict correction. Simulated pressures on the torso and distance between the brace and patient's skin were used to remove ineffective brace material situated at more than 6 mm from the patient's skin. Biplanar radiographs of the patient wearing each brace were taken to compare their effectiveness. Patients filled out a questionnaire to compare their comfort. NewBraces were 61% thinner and had 32% less material than standard braces with equivalent correction. NewBraces were more comfortable (11 of 15 patients) or equivalent to (4 of 15 cases) standard braces. Simulated correction was simulated within 5° compared with in-brace results. This study demonstrates the feasibility of designing lighter and more comfortable braces with correction equivalent to standard braces. This design platform has the

  10. An investigation into the cause of the inner dark areas and outer lighter areas (ghosting) seen in dynamically-created two-dimensional bare footprints.

    Dynamic bare footprints differ from static bare footprints through the presence of additional, lighter markings around the rear of the heel print and apices of the toe print areas. These images can appropriately be described as inner dark and outer ghosting features. To date, the functional cause of both features has not been understood. To gain such an understanding could potentially allow the further development and use of these features in forensic identification. The aim of this project was to investigate the causes of the inner dark and outer ghosting features seen in dynamic bare footprints through an observational, practice-based action research approach within a gait laboratory. Volunteer male participants provided bare footprints on inkless paper taped to a Kistler force plate with video cameras situated either side. Ground reaction force data were collected as the footprints were formed and the event recorded using video cameras to allow these data to be correlated later. The findings suggest that the ghosting at the heel is the result of splaying of the fibro fatty pad, while that at the toes is the result of the distal ends of the toes coming into contact with the ground as the heel is lifted. Footprint, ground reaction force and video data comparisons showed that the inner dark area of the heel print corresponded with the main body of the heel contacting the ground. Outer ghosting corresponded with a backward splaying of the fat pad and the heel strike transient spike in vertical ground reaction force during increased loading. The inner dark area of the toes corresponded with a longer period of toe contact with the ground. Outer ghosting corresponded with the decreasing vertical ground reaction force and shorter contact time as the toes were leaving the ground towards the end of the contact phase of gait. Although the sample size was limited, these are new appreciations which could facilitate the use of the inner dark features in identification to

    Broad Funding Opportunity Announcement Project: GM is using shape memory alloys that require as little as a 10°C temperature difference to convert low-grade waste heat into mechanical energy. When a stretched wire made of shape memory alloy is heated, it shrinks back to its pre-stretched length. When the wire cools back down, it becomes more pliable and can revert to its original stretched shape. This expansion and contraction can be used directly as mechanical energy output or used to drive an electric generator. Shape memory alloy heat engines have been around for decades, but the few devices that engineers have built were too complex, required fluid baths, and had insufficient cycle life for practical use. GM is working to create a prototype that is practical for commercial applications and capable of operating with either air- or fluid-based heat sources. GM’s shape memory alloy based heat engine is also designed for use in a variety of non-vehicle applications. For example, it can be used to harvest non-vehicle heat sources, such as domestic and industrial waste heat and natural geothermal heat, and in HVAC systems and generators.

    Inflatable systems have widespread applications in military, government, and industrial sectors. Improvements in inflatable materials have followed each salient advancement in textiles. The new organic fiber, Kevlar, is a recent and most significant advancement that justified reexamination of old and new inflatable materials' applications. A fertile frontier exists in integrating Kevlar with various other material combinations, in optimization of geometric features, and in selection of thermomechanical characteristics' compatibility with the environment. Expectations regarding Kevlar have been justified by the performance of two experimental materials. Styrene-butadiene-styrene block copolymers appear promising as a constituent adhesive for low temperature applications. Biaxial testing for both strength and material elastic properties is a technology area needing greater awareness and technology growth along with improved facilities. Because of dramatic materials' advancements, inflatable systems appear to be moving toward an increased position in tomorrow's aerospace industry.

  15. A Lighter-Than-Air System Enhanced with Kinetic Lift

    NASA Technical Reports Server (NTRS)

    Spearman, M. Leroy

    2002-01-01

    A hybrid airship system is proposed in which the buoyant lift is enhanced with kinetic lift. The airship would consist of twin hulls in which the buoyant gas is contained. The twin hulls would be connected in parallel by a wing having an airfoil contour. In forward flight, the wing would provide kinetic lift that would add to the buoyant lift. The added lift would permit a greater payload/altitude combination than that which could be supported by the buoyant lift alone. The buoyant lift is a function of the volume of gas and the flight altitude. The kinetic lift is a function of the airfoil section, wing area, and the speed and altitude of flight. Accordingly there are a number of factors that can be manipulated to arrive at a particular design. Particular designs could vary from small, lightweight systems to very large, heavy-load systems. It will be the purpose of this paper to examine the sensitivity of such a design to the several variables. In addition, possible uses made achievable by such a hybrid system will be suggested.

    The aim of this study was to determine whether patient volume in an urban pediatric emergency department (ED) can be predicted based on holidays and thus aid in staffing and resource allocation. Log-in dates and times were obtained for all patients seen in an urban pediatric ED between July 1, 2006, and June 30, 2013. Visits were coded for the day of the week, tour (ie, shift), and season and whether they occurred on a holiday or nonholiday. Comparisons between the median number of patient visits on holidays versus nonholidays by day of the week, tour, and season were performed. Additional comparisons on 5 Monday holidays as well as New Year's Day, Thanksgiving, and Christmas Day were also performed. Data were presented as medians with interquartile ranges. Group comparisons were performed via using Mann-Whitney U tests and Kruskal-Wallis tests (α = 0.05, 2 tailed). There were 223,677 total patient visits, with a mean yearly census of 31,954. The median daily volume was 85, peaking on Mondays (median, 99). The summer season demonstrated the fewest number of patient visits (median, 74) relative to the other seasons (medians, 89-91). Compared with nonholidays, there were fewer patient visits on Thanksgiving and Christmas Day and in the late afternoon and evening on other individual holidays. Fewer patient visits on Thanksgiving and Christmas Days, as well as during the late afternoon/evening on several other holidays, point to the possibility of small adjustments to staffing in ways that can more efficiently balance demand with available resources.

First flown in 1959 from the NASA High Speed Flight Station (later renamed the Dryden Flight Research Center), the rocket powered X-15 was developed to provide data on aerodynamics, structures, flight controls and the physiological aspects of high speed, high altitude flight. Three were built by North American Aviation for NASA and the U.S. Air Force. They made a total of 199 flights during a highly successful research program lasting almost ten years, following which its speed and altitude records for winged aircraft remained unbroken until the Space Shuttle first returned from earth orbit in 1981. The X-15's main rocket engine provided thrust for the first 80 to 120 seconds of a 10 to 11 minute flight; the aircraft then glided to a 200 mph landing. The X-15 reached altitudes of 354,200 feet (67.08 miles) and a speed of 4,520 mph (Mach 6.7).

    We report a search for narrow resonances, produced in pbar{p} collisions at sqrt{s}=1.96 TeV, that decay into muon pairs with invariant mass between 6.3 and 9.0 GeV/ c 2. The data, collected with the CDF II detector at the Fermilab Tevatron collider, correspond to an integrated luminosity of 630 pb-1. We use the dimuon invariant mass distribution to set 90% upper credible limits of about 1% to the ratio of the production cross section times muonic branching fraction of possible narrow resonances to that of the ϒ(1S) meson.

  20. The lighter side of advertising: investigating posing and lighting biases.

    People tend to display the left cheek when posing for a portrait; however, this effect does not appear to generalise to advertising. The amount of body visible in the image and the sex of the poser might also contribute to the posing bias. Portraits also exhibit lateral lighting biases, with most images being lit from the left. This effect might also be present in advertisements. A total of 2801 full-page advertisements were sampled and coded for posing direction, lighting direction, sex of model, and amount of body showing. Images of females showed an overall leftward posing bias, but the biases in males depended on the amount of body visible. Males demonstrated rightward posing biases for head-only images. Overall, images tended to be lit from the top left corner. The two factors of posing and lighting biases appear to influence one another. Leftward-lit images had more leftward poses than rightward, while the opposite occurred for rightward-lit images. Collectively, these results demonstrate that the posing biases in advertisements are dependent on the amount of body showing in the image, and that biases in lighting direction interact with these posing biases.

  1. Majorana vs. Dirac sterile neutrinos lighter than MW at the LHC

    We propose to study the leptonic decays W± → e±e±µ ∓ ν and W± → µ±µ±e ∓ ν at the LHC to discover sterile neutrinos with masses below MW , and discriminate their Majorana or Dirac character. These decays are induced by a sterile neutrino N that goes on mass shell in the intermediate state. We find that, even though the final (anti-)neutrino goes undetected and thus lepton number is unchecked, one can distinguish between the Majorana vs. Dirac character of the intermediate sterile neutrino by comparing the production of e±e±µ ∓ vs. µ±µ±e ∓, provided the N-e and N-µ mixings are different enough. Alternatively, one can also distinguish the Majorana vs. Dirac character by studying the energy spectra of the opposite charge lepton, a method that works even if the N-e and N-µ mixings are equal.

    2016-12-01

    Research on collective efficacy in urban neighborhoods has focused predominantly on whether a community can regulate local behavior and spaces and less on how they do so. This study pursues the latter question by examining the social regularities that create collective efficacy, measured as the behavioral composition of a neighborhood (i.e., the extent to which each individual contributes to a social regularity). This perspective is applied to the database of requests for non-emergency government services received by Boston, MA's 311 system in 2011 (>160,000 requests). The analysis categorized custodians who have used the system to combat physical disorder in the public space (e.g., requesting graffiti removal) into two groups-"typical custodians" who have made one or two requests in a year, and "exemplars" who have made three or more. A neighborhood's collective efficacy in reporting public issues was identified through audits of sidewalk quality and streetlight outages. Analyses revealed a collaborative model of maintenance in which typical and exemplar custodians were each necessary and non-substitutable. A second analysis found that the two types of custodian were associated with different contextual factors, articulating two different pathways from demographic and social characteristics to collective efficacy, suggesting implications for theory and practice. © Society for Community Research and Action 2016.

    Artificial muscles based on dielectric elastomers show enormous promise for a wide range of applications and are slowly moving from the lab to industry. One problem for industrial uptake is the expensive, rigid, heavy and bulky high voltage driver, sensor and control circuitry that artificial muscle devices currently require. One recent development, the Dielectric Elastomer Switch(es) (DES), shows promise for substantially reducing auxiliary circuitry and helping to mature the technology. DES are piezoresistive elements that can be used to form logic, driver, and sensor circuitry. One particularly useful feature of DES is their ability to embed oscillatory behaviour directly into an artificial muscle device. In this paper we will focus on how DES oscillators can break down the barriers to industrial adoption for artificial muscle devices. We have developed an improved artificial muscle ring oscillator and applied it to form a mechanosensitive conveyor. The free running oscillator ran at 4.4 Hz for 1056 cycles before failing due to electrode degradation. With better materials artificial muscle oscillators could open the door to robots with increased power to weight ratios, simple-to-control peristaltic pumps, and commercially viable artificial muscle motors.

  5. Neutrinos secretly converting to lighter particles to please both KATRIN and the cosmos

    2016-02-01

    Within the framework of the Standard Model of particle physics and standard cosmology, observations of the Cosmic Microwave Background (CMB) and Baryon Acoustic Oscillations (BAO) set stringent bounds on the sum of the masses of neutrinos. If these bounds are satisfied, the upcoming KATRIN experiment which is designed to probe neutrino mass down to ∼ 0.2 eV will observe only a null signal. We show that the bounds can be relaxed by introducing new interactions for the massive active neutrinos, making neutrino masses in the range observable by KATRIN compatible with cosmological bounds. Within this scenario, neutrinos convert to new stable light particles by resonant production of intermediate states around a temperature of T∼ keV in the early Universe, leading to a much less pronounced suppression of density fluctuations compared to the standard model.

    A new energy paradigm, consisting of greater reliance on renewable energy sources and increased concern for energy efficiency in the total energy lifecycle, has accelerated research into energy-related technologies. Due to their ubiquity, magnetic materials play an important role in improving the efficiency and performance of devices in electric power generation, conditioning, conversion, transportation, and other energy-use sectors of the economy. This review focuses on the state-of-the-art hard and soft magnets and magnetocaloric materials, with an emphasis on their optimization for energy applications. Specifically, the impact of hard magnets on electric motor and transportation technologies, of soft magnetic materials on electricity generation and conversion technologies, and of magnetocaloric materials for refrigeration technologies, are discussed. The synthesis, characterization, and property evaluation of the materials, with an emphasis on structure-property relationships, are discussed in the context of their respective markets, as well as their potential impact on energy efficiency. Finally, considering future bottlenecks in raw materials, options for the recycling of rare-earth intermetallics for hard magnets will be discussed. Copyright © 2011 WILEY-VCH Verlag GmbH & Co.

    To determine the effect of shoe mass on performance in basketball-specific movements and how this affects changes if an athlete is aware or not of the shoe's mass relative to other shoes. In an experimental design, 22 male participants were assigned to 2 groups. In the "aware" group, differences in the mass of the shoes were disclosed, while participants in the other group were blinded to the mass of shoes. For both groups lateral shuffle-cut and vertical-jump performances were quantified in 3 different basketball-shoe conditions (light, 352 ± 18.4 g; medium, 510 ± 17 g; heavy, 637 ± 17.7 g). A mixed ANOVA compared mean shuffle-cut and vertical-jump performances across shoes and groups. For blinded participants, perceived shoe-weight ratings were collected and compared across shoe conditions using a Friedman 2-way ANOVA. In the aware group, performance in the light shoes was significantly increased by 2% (vertical jump 2%, P < .001; shuffle cut 2.1%, P < .001) compared with the heavy shoes. In the blind group, participants were unable to perceive the shoe-weight variation between conditions, and there were no significant differences in vertical-jump and shuffle-cut performance across shoes. Differences in performance of the aware participants were most likely due to psychological effects such as positive and negative expectancies toward the light and heavy shoes, respectively. These results underline the importance for coaches and shoe manufacturers to communicate the performance-enhancing benefits of products or other interventions to athletes to optimize their performance outcome.

    Chronic pain and tobacco smoking are both highly prevalent and comorbid conditions, and chronic pain may pose a barrier to smoking cessation. The objective of this study was to test associations between chronic pain status and several smoking-related factors that have previously been shown to predict cessation outcomes. Daily smokers (N = 205) were recruited from the general population to complete an online survey of pain and tobacco smoking. Results indicated that smokers with chronic pain (vs. no chronic pain) consumed more cigarettes per day, scored higher on an established measure of tobacco dependence, reported having less confidence in their ability to quit, and endorsed expectations for experiencing greater difficulty and more severe nicotine withdrawal during future cessation attempts. Mediation analyses further indicated that the inverse association between chronic pain and abstinence self-efficacy was indirectly influenced by past cessation failures. These findings suggest that individuals with chronic pain may constitute an important subgroup of tobacco smokers who tend to experience lower confidence and greater difficulty when attempting to quit. Future research would benefit from replicating these findings among older and more diverse samples of heavier tobacco smokers, and extending this work to the study of prospective relations between chronic pain status and cessation-relevant processes/outcomes over the course of a quit attempt.

    Powered LTA vehicles have historically been limited to operations at low altitudes. Conditions exist which may enable a remotely piloted unit to be operated at an altitude near 70,000 feet. Such systems will be launched like high altitude balloons, operate like nonrigid airships, and have mission capabilities comparable to a low altitude stationary satellite. The limited lift available and the stratospheric environment impose special requirements on power systems, hull materials and payloads. Potential nonmilitary uses of the vehicle include communications relay, environmental monitoring and ship traffic control.

    By the year 2020 it is estimated that there will be more than 50 billion devices connected to the Internet. These devices not only include traditional electronics such as smartphones and other mobile compute devices, but also eEnabled technologies such as cars, airplanes and smartgrids. The IoT brings with it the promise of efficiency, greater remote management of industrial processes and further opens the doors to world of vehicle autonomy. However, IoT enabled technology will have to operate and contend in the contested domain of cyberspace. This discussion will touch on the impact that cybersecurity has on IoT and the people, processes and technology required to mitigate cyber risks.

  8. Adsorption of the Lighter Homologs of Element 104 and Element 105 on DGA Resin from Various Mineral Acids

    The goal of studying transactinide elements is to further understand the fundamental principles that govern the periodic table. The current periodic table arrangement allows for the prediction of the chemical behavior of elements. The correct position of a transactinide element can be assessed by investigating its chemical behavior and comparing it to that of the homologs and pseudo-homologs of a transactinide element. Homologs of a transactinide element are the elements in the same group of the periodic table as the transactinide. A pseudo-homolog of a transactinide element is an element with a similar main oxidation state and similar ionic radius to the transactinide element. For example, the homologs of rutherfordium, Rf, are titanium, zirconium and hafnium (Ti, Zr and Hf); the pseudo homologs of Rf are thorium, Th, and plutonium, Pu. Understanding the chemical behavior of a transactinide element compared to its homologs and pseudo-homologs also allows for the assessment of the role of relativistic effects. Relativistic effects occur when the velocity of the s orbital electrons closest to the nucleus approaches the speed of light. These electrons approach the speed of light because they have no orbital momentum. This causes two effects, first there is in a decrease in Bohr radius of the inner electronic orbitals because of this there is an increase in particle mass. A contraction of outer s and p orbitals is also seen. The contraction of these orbitals results in an energy destabilization of the outer most shell, in the case of transactinides this would be the 5f and 6d orbitals. The outer most d shell and all f shells can also experience a radial expansion due to these orbitals being screened from the effective nuclear charge. Another relativistic effect is the 'spin-orbit splitting' for p, d and f orbitals into j = 1 {+-} 1/2 states. Where j is the total angular momentum vector and 1 is angular quantum number. All of these effects have the same order of magnitude and increase roughly according to Z. This feature is what makes studying the heavy elements so interesting because the chemical properties of transactinide elements should strongly exhibit these effects. For this work the terms heavy element and transactinide elements will be used interchangeably and are defined as elements with an atomic number greater than 103, Z > 103. In order to study the transactinide elements they must be isolated once they have been produced and transported to a chemistry apparatus. The transactinide elements are produced either via 'hot' or 'cold' fusion reactions. 'Hot' fusion reactions result in excitation energies of the compound nucleus of 40-50 MeV and occur when an actinide target nuclei fuse with a projectile with A < 40, where A is the atomic mass number. 'Cold' fusion results in excitation energies of 10-15 MeV. Cold fusion conditions tend to occur when a target of a spherical nuclei (Pb or Bi) is bombarded with a heavy projectile (A > 40). Hot fusion generally leads to neutron rich isotopes and cold fusion tends to produce a compound nucleus that emits 1-2 neutrons upon de-excitation. If a sufficiently thin target is employed, then the products of the nuclear reaction will recoil out of the target and can either be transported to the chemistry setup, e.g. using a gas jet, or trapped by implementing them on a catcher. An example for a catcher setup using a copper block as a catcher is described here. The copper block is placed behind the target during the irradiation and all nuclei recoiling from the target position will implant themselves in the block. The copper block is subsequently dismounted and sputter cleaned. It is then shaved with a micro-lathe. The 7-10 {micro}m copper shavings are then subjected to chemical separation. The copper is dissolved in aqua regia. Lanthanum carrier is added to the aqua regia to precipitate tri-, tetra- and penta- valent cations when ammonium hydroxide is added. The precipitate is then washed and converted to the nitrate form. This solution is then added onto a cation exchange column, the eluent is deposited and dried on a polypropylene film and then counted on solid state detectors. There are several challenges when studying the chemical behavior of transactinide elements. The first challenge is the low production rate of transactinides. Transactinides are produced on an atom-at-a-time basis, meaning that only one atom is ever available for chemical study. Because of this the chemical system being used must be selective for only one chemical state. The second challenge in transactinide chemistry is the short half-lives of the elements. Half-lives of the transactinides range from nanoseconds to a few hours. This leads to the need for fast chemistry. Another challenge is the need for a high degree of separation from interfering radionuclides so that the event with the transactinide element can be detected.

The stable phases in systems of La and Nd, are Ln(OH)CO 3-B, Ln 2O 2CO 3-II and LnOOH, in addition to the Ln(OH) 3 phase at extremely low partial pressures of CO 2 in the system. The systems become more and more complex with decreasing ionic radi and the number of stable carbonate phases increases. Ln 2(CO 3) 3 · 3H 2O orthorhombic (tengerate-like phase) is stable from Sm to Gd in addition to the other phases. The Gd(OH)CO 3-A (ancylite-like phase) is hydrothermally stable at XCO 2 ⩾ 0.5 while its hexagonal polymorph, Gd(OH)CO 3-B is stable at low partial pressures of CO 2 in the system.

  10. Narratives of nostalgia in the face of death: The importance of lighter stories of the past in palliative care.

    PubMed

    Synnes, Oddgeir

    2015-08-01

    My research on the stories of palliative care patients emphasizes the heterogeneity of the types of stories they tell, including stories of illness, of everyday life, of the future, and of the past (Synnes, 2012). This article pays special attention to the prevalence of stories of past experiences in which the past is portrayed through idyllic and nostalgic interpretation. In contrast to most research on illness narratives and narrative gerontology that is preoccupied with stories of change, these stories of nostalgia are characterized by a plot where nothing in particular happens. However, this may be the primary purpose for the storytellers in their particular situation of illness and imminent death. The main purpose of nostalgia is precisely to ensure the continuity of identity in the face of adversity (Davis, 1979). In this article, I argue that these stories of nostalgia are vital aspects of maintaining the continuity of the self, or a narrative identity, when much else in life is characterized by discontinuity and uncertainty. Thus, stories of nostalgia should not be dismissed as escapism but valued and listened to as important aspects of narrative care among palliative care patients, and as a way of preserving the sense of a narrative identity.

    Reported is a new method to apply cosmic-ray tomography in a manner that can detect and characterize not only dense assemblages of heavy nuclei (like Special Nuclear Materials, SNM) but also assemblages of medium- and light-atomic-mass materials (such as metal parts, conventional explosives, and organic materials). Characterization may enable discrimination between permitted contents in commerce and contraband (explosives, illegal drugs, and the like). Our Multi-Mode Passive Detection System (MMPDS) relies primarily on the muon component of cosmic rays to interrogate Volumes of Interest (VOI). Muons, highly energetic and massive, pass essentially un-scattered through materials of light atomic mass and are only weakly scattered by conventional metals used in industry. Substantial scattering and absorption only occur when muons encounter sufficient thicknesses of heavy elements characteristic of lead and SNM. Electrons are appreciably scattered by light elements and stopped by sufficient thicknesses of materials containing medium-atomic-mass elements (mostly metals). Data include simulations based upon GEANT and measurements in the HMT (Half Muon Tracker) detector in Poway, CA and a package scanner in both Poway and Socorro NM. A key aspect of the present work is development of a useful parameter, designated the "stopping power" of a sample. The low-density regime, comprising organic materials up to aluminum, is characterized using very little scattering but a strong variation in stopping power. The medium-to-high density regime shows a larger variation in scattering than in stopping power. The detection of emitted gamma rays is another useful signature of some materials.

  18. Flavor violating signatures of lighter and heavier Higgs bosons within the two Higgs doublet model type III at the LHeC

    We analyze the prospects for observing the light and heavy C P -even neutral Higgs bosons (ϕ =h and H ) in their decays into flavor violating b s ¯ channels (including charge conjugation) at the proposed Large Hadron electron Collider (LHeC), with √{s }≈1.3 TeV , in the framework of a 2-Higgs doublet model (2HDM) Type III, assuming a four-zero texture in the Yukawa matrices and a general Higgs potential. We consider theoretically consistent scenarios in agreement with current experimental data from flavor and Higgs physics. We investigate the charged current production process νeϕ q in presence of flavor violating decays of the Higgs bosons, that lead to a 3 -jets+ ET signature. We demand exactly two jets, one tagged b -jet and one light-flavor jet, all in the central rapidity region. The remaining jet (originated by the remnant quark q ) is tagged in the forward or backward regions and this together with a central jet veto (not more than one light-flavor jet) are essential criterions to enhance the signal-to-background rates. We consider the most relevant standard model (SM) backgrounds, treating c -jets separately from light-flavor and gluon ones, while allowing for mistagging. We find that the SM-like Higgs boson, h , would be accessible within several parameter configurations of our model at approximately the 1 -2 σ level with 100 fb-1 of data. We also find that the heaviest neutral Higgs boson, H , with mass up to 150 GeV, would have a 1 σ significance for the same data sample. At the end of the LHeC running, one would have ten times data accumulation and for all the Higgs masses the significances are enhanced so as to allow for detection of both the h and H state. Hence, one of the most viable extensions of 2HDMs with flavor changing neutral currents (FCNCs) generated at tree level but controlled by a four-zero texture approach in the Yukawa matrices, as opposed to the adoption of ad hoc discrete symmetries, could be put under scrutiny at a future e p machine.

  19. Development of a home-made extraction device for vortex-assisted surfactant-enhanced-emulsification liquid-liquid microextraction with lighter than water organic solvents.

    We have developed a novel vortex-assisted surfactant-enhanced-emulsification liquid-liquid microextraction using the low density solvent for the determination of eight organophosphorus pesticides (OPPs) in water samples. The key point of this method is the application of a special home-made extraction device. The influence parameters relevant to this method were systemically investigated and the optimum conditions were as follow: 35μL of toluene was used as extraction solvent and 0.2mmol L-1 Triton X-100 was chosen as the surfactant to enhance the emulsification. Under the optimum experimental conditions, the limit of detections (LODs) of the method was ranged between 0.01 and 0.05μgL(-1) and the relative standard deviations (RSDs) were 2.9-8.1%. The calibration curve was linear in the range of 0.1-50.0μgL(-1), with the correlation coefficients (r) varying from 0.9949 to 0.9991. Finally, the developed method has been successfully applied to the determination of eight organophosphorus pesticides in river, reservoir and well water samples with recoveries between 82.1% and 98.7%.

    Prediction of the histopathological subtype of basal cell carcinoma (BCC) is important for tailoring optimal treatment, especially in patients with suspected superficial BCC (sBCC). To assess the accuracy of the preoperative prediction of subtypes of BCC in clinical practice, to evaluate whether dermoscopic examination enhances accuracy and to find dermoscopic criteria for discriminating sBCC from other subtypes. The main presurgical diagnosis was compared with the histopathological, postoperative diagnosis of routinely excised skin tumours in a predominantly fair-skinned patient cohort of northern Europe during a study period of 3 years (2011-13). The study period was split in two: during period 1, dermoscopy was optional (850 cases with a pre- or postoperative diagnosis of BCC), while during period 2 (after an educational dermoscopic update) dermoscopy was mandatory (651 cases). A classification tree based on clinical and dermoscopic features for prediction of sBCC was applied. For a total of 3544 excised skin tumours, the sensitivity for the diagnosis of BCC (any subtype) was 93·3%, specificity 91·8%, and the positive predictive value (PPV) 89·0%. The diagnostic accuracy as well as the PPV and the positive likelihood ratio for sBCC were significantly higher when dermoscopy was mandatory. A flat surface and multiple small erosions predicted sBCC. The study shows a high accuracy for an overall diagnosis of BCC and increased accuracy in prediction of sBCC for the period when dermoscopy was applied in all cases. The most discriminating findings for sBCC, based on clinical and dermoscopic features in this fair-skinned population, were a flat surface and multiple small erosions. © 2016 British Association of Dermatologists.

  1. High-density lipoprotein cholesterol esterification and transfer rates to lighter density lipoproteins mediated by cholesteryl ester transfer protein in the fasting and postprandial periods are not altered in type 1 diabetes mellitus.

    2000-10-01

    Background: Diabetes mellitus is associated with atherosclerosis that has, in part, been ascribed to abnormalities in the reverse cholesterol transport system. Methods: We determined, in the fasting and post-alimentary periods, rates of HDL cholesterol esterification and transfer to apoB-containing lipoproteins, cholesteryl ester transfer protein (CETP) concentration, and apoB lipoprotein size in 10 type 1 diabetics and 10 well-matched controls. Autologous HDL was labeled with [14C]cholesterol and incubated at 37 degrees C during a period of 30 min for measurement of the cholesterol esterification rate (CER), as well as for 24 h for measurement of the endogenous HDL [14C]cholesteryl ester ([14C]CE) transfer rate to apoB-containing lipoproteins after 2- and 4-h incubations with the subject's own plasma. Exogenous cholesteryl ester transfer activity (CETA) was estimated by incubation of the participant's plasma (CETP source) with [14C]CE-HDL and VLDL from a pool of plasma donors. ApoB lipoprotein size was determined using non-denaturing polyacrylamide gradient gel electrophoresis of whole plasma. Results: Contrary to previous studies, we showed that even not well-controlled type 1 diabetics did not differ from lipid-matched, non-diabetic subjects in HDL-[14C]cholesterol esterification rate, transfer rates, or CETP concentration. CETP concentration correlates with the exogenous method of [14C]CE transfer and with the endogenous method only when the latter is corrected for plasma triacylglycerol (TG) concentration. In addition, during the postprandial phase, diabetic patients' VLDL are smaller and IDL size increases less than in controls. Conclusion: In type 1 diabetes mellitus, CETA is not altered when the plasma levels of donor and/or acceptor lipoproteins are within the normal range.

    Esztermann, A.; Löwen, H.

    2004-10-01

    Equilibrium sedimentation density profiles of charged binary colloidal suspensions are calculated by computer simulations and density-functional theory. For deionized samples, we predict a colloidal "Brazil nut" effect: heavy colloidal particles sediment on top of the lighter ones provided that their mass per charge is smaller than that of the lighter ones. This effect is verifiable in settling experiments.

  8. Flux pinning enhancement in melt processed YBa2Cu3O7 - delta through rare-earth ion (Nd, La) substitutions

    NASA Astrophysics Data System (ADS)

    Varanasi, Chakrapani; McGinn, Paul J.; Blackstead, Howard A.; Pulling, David B.

    1995-08-01

    Stoichiometric YBa2Cu3O7-δ (Y123) samples doped with excess Nd2O3 and La2O3 additions were melt processed in air. Because decomposition and reformation of 123 occurs during melt processing, lighter rare-earth ion substitution in 123 takes place. As the lighter rare-earth ion sizes (Nd, La) are comparable to that of Ba2+, in addition to Y ion site substitution, partial substitution into the Ba2+ sites is also anticipated. The Tc and magnetic properties of lighter rare-earth oxide doped samples were analyzed and compared with undoped Y123 to investigate the flux pinning enhancement due to these substitutions. The lighter rare-earth oxide doped, melt processed 123 shows significant improvement in magnetization compared to undoped samples, which is likely due to point defects created by partial substitutions of the lighter rare-earth ions.

  10. Single-bubble sonoluminescence from noble gases.

    PubMed

    Yasui, K

    2001-03-01

    Single-bubble sonoluminescence (SBSL) from noble gases in water is studied theoretically in order to clarify the reason of the distinguished feature that the luminescence is strong for all noble gases, while the other systems of cavitation luminescence are greatly enhanced by the presence of the heavy noble gas(xenon). It is clarified that in spite of the larger thermal conductivity of lighter noble gases the maximum temperature in a SBSL bubble of lighter noble gases is higher due both to the segregation of water vapor and noble gas inside a SBSL bubble and the stronger acoustic drive of a SBSL bubble of lighter noble gases.

  12. Steel cars face a weighty decision

    SciTech Connect

    Ashley, S.

    1997-02-01

    This article describes how pressure to improve automotive gas mileage is driving efforts to find new ways to reduce the weight of steel car-body structures. The automobile has been on an extended weight-loss program for several decades now. Ever since the oil shortages of the 1970s and the subsequent adoption of tougher environmental regulations, auto engineers have been whittling away at vehicle weight as a way to boost fuel economy and reduce exhaust emissions. The lighter they can make a vehicle, the lighter its body structure and suspension system could be, and the lighter the engine that would be needed.

  8. Modeling of marine litter drift and beaching in the Japan Sea.

    PubMed

    Yoon, Jong-Hwan; Kawano, Shiro; Igawa, Shuzo

    2010-03-01

    Characteristics of drift and beaching of floating marine litter in the Japan Sea are examined numerically using the reanalysis data of the Japan Sea Forecasting System of Kyushu University. The residence time of model marine litter deployed uniformly over the surface of the Japan Sea strongly depends on the buoyancy ratio. However, almost all litter beaches or flows out through straits within 3years. Experiments with inputs of litter imposed at large cities and the Tsushima Straits as well as river basins of the Japan Sea exhibit a good agreement with beach surveys with regard to country ratios of beached litter along the Japanese coast in cases of lighters. In a case of lighter, almost all lighters originating from Japan beach along the Japanese coast, while almost all lighters originating from a country surrounding the Japan Sea except Japan beach along the coast of that country and the Japanese coast.

    The present study sought to learn about risk perceptions held by parents of preschool fire-setters. A 41-item survey was distributed to 60 parents whose children, aged 6 years and younger, had previously set fires and who were involved in intervention programmes throughout the US. Most parents did not think their children would play with matches/lighters, or knew how to use these items, although some had witnessed their children playing with matches/lighters previously. Most parents reported having taken precautions to keep matches/lighters out of reach and also educating their children about fire. Regardless, children not only set fires, but in 40% of cases climbed to access the match/lighter. Parents' perceptions of their children's proclivity for fire play were not consistent with their actual fire-play behaviour. Parents underestimated the likelihood that their children would play with matches/lighters. Although most reportedly undertook preventative measures aimed at thwarting fire play, these strategies were ineffective. Traditionally relied upon precautionary techniques, such as storing lighters out of reach and discussing the dangers of fire, were not sufficient to stem interest and resultant fire play.

    A long-standing debate surrounds the issue of whether human and nonhuman species share similar perceptual mechanisms. One experimental strategy to compare visual perception of vertebrates consists in assessing how animals react in the presence of visual illusions. To date, this methodological approach has been widely used with mammals and birds, while few studies have been reported in distantly related species, such as fish. In the present study we investigated whether fish perceive the brightness illusion, a well-known illusion occurring when 2 objects, identical in physical features, appear to be different in brightness. Twelve guppies (Poecilia reticulata) were initially trained to discriminate which rectangle was darker or lighter between 2 otherwise identical rectangles. Three different conditions were set up: neutral condition between rectangle and background (same background used for both darker and lighter rectangle); congruent condition (darker rectangle in a darker background and lighter rectangle in a lighter background); and incongruent condition (darker rectangle in a lighter background and lighter rectangle in a darker background). After reaching the learning criterion, guppies were presented with the illusory pattern: 2 identical rectangles inserted in 2 different backgrounds. Guppies previously trained to select the darker rectangle showed a significant choice of the rectangle that appears to be darker by human observers (and vice versa). The human-like performance exhibited in the presence of the illusory pattern suggests the existence of similar perceptual mechanisms between humans and fish to elaborate the brightness of objects.

  17. Investigation, by single photon ionisation (SPI)-time-of-flight mass spectrometry (TOFMS), of the effect of different cigarette-lighting devices on the chemical composition of the first cigarette puff.

    2007-01-01

    Soft single-photon ionisation (SPI)-time-of-flight mass spectrometry (TOFMS) has been used to investigate the effect of different cigarette-lighting devices on the chemical composition of the mainstream smoke from the first cigarette puff. Lighting devices examined were a Borgwaldt electric lighter, a propane/butane gas lighter, a match, a candle, and the burning zone of another cigarette. To eliminate the effects of the different masses of tobacco burnt by use of the different lighting methods a normalisation procedure was performed which enabled investigation of changes in the chemical patterns of the resulting smoke. When another cigarette was used as the lighting device, elevated levels of ammonia and other nitrogen-containing substances were observed. These are high in the sidestream smoke of the cigarette used for lighting and would be drawn into the mainstream smoke of the cigarette being lit. In contrast, smoke from the cigarette lit by the electric lighter contained slightly higher normalised amounts of isoprene. Lighting the cigarette by use of a candle resulted in larger amounts of substances, e.g. benzene, which most probably originated from thermal decomposition of wax. The composition of the first puff of smoke obtained by use of the three lighting methods with open flames (gas lighter, match, and candle) was usually similar whereas the composition of the smoke produced by use of the electric lighter and the cigarette as the lighter were more unique. The chemical patterns generated by the different lighting devices could, however, be separated by principal-component analyses. Two additional test series were also studied. In the first the cigarette was lit with an electric lighter, then extinguished, the ash was cut off, and the cigarette was re-lit. In the second the cigarette was heated in an oven to 80 degrees C for 5 min before being lit. These treatments did not result in changes in the chemical composition compared with cigarettes lit in the

  18. Calcium isotope fractionation between soft and mineralized tissues as a monitor of calcium use in vertebrates

    PubMed Central

    Skulan, Joseph; DePaolo, Donald J.

    1999-01-01

    Calcium from bone and shell is isotopically lighter than calcium of soft tissue from the same organism and isotopically lighter than source (dietary) calcium. When measured as the 44Ca/40Ca isotopic ratio, the total range of variation observed is 5.5‰, and as much as 4‰ variation is found in a single organism. The observed intraorganismal calcium isotopic variations and the isotopic differences between tissues and diet indicate that isotopic fractionation occurs mainly as a result of mineralization. Soft tissue calcium becomes heavier or lighter than source calcium during periods when there is net gain or loss of mineral mass, respectively. These results suggest that variations of natural calcium isotope ratios in tissues may be useful for assessing the calcium and mineral balance of organisms without introducing isotopic tracers.

    Synergistic extraction of trivalent lanthanides(Ln) was investigated using thenoyltrifluoroacetone(HTTA) and crown ether(CE). Characteristic ion-pair extraction of the lighter Ln(III) was observed with 1,2-dichloroethane containing HTTA and 18-crown-6 or dicyclohexano-18-crown-6, in which the cationic complex, Ln(TTA){sub 2}CE{sup +}, was formed and extracted. Remarkable increases of an extractability and a selectivity were attained in the synergistic ion-pair extraction of the lighter Ln ions, which could be elucidated on the basis of size-fitting effect in the complex formation of the lighter Ln ions with CE. 19 refs., 2 figs., 3 tabs.

    The purpose of this article is to describe deep facial burn injuries by cigarette lighters in longhaired adults and to report our experience in their treatment. Eight consecutive cigarette lighter burn victims are treated in the Helsinki Burn Center in the year 2006. Seven of the patients were women; their mean age was 50 years. All were under the influence of alcohol at the time of injury. The mean burnt area was 3.5% TBSA. The burnt areas were primarily forehead, cheek, and ipsilateral ear. After a conservative treatment, all the patients underwent an operation, whereby the nonhealing burns were excised and covered with autologous split thickness skin grafts. Postoperative period was uneventful in all the patients. Besides having severe detrimental effects on general health status and wound healing, smoking is the leading cause of residential and total fire deaths worldwide. The patients in this article suffered deep facial burns because of cigarette lighters.

  14. Deformation of the overriding slab during incipient subduction in centrifuge modeling and its tectonic significance

    NASA Astrophysics Data System (ADS)

    Mart, Yossi; Goren, Liran; Koyi, Hemin

    2015-04-01

    Analog models of subduction-related structural deformation emphasize the significance of differences in density and friction between the adjacent plates on the distortion of the overriding slab and its possible effect on the subduction procedure. Centrifuge experiments juxtaposed miniaturized lighter and denser lithospheres, which were floating on denser but less viscous asthenosphere. The lithosphere in the tests comprised brittle and ductile strata, which showed diversified styles of deformation, while factors of equivocal tectonic significance, such as lateral push or negative buoyancy, were not introduced into the experiments. The tests show that the juxtaposition of lighter and denser lithospheres would suffice to drive the denser lithosphere as a wedge between the asthenosphere and the lighter lithosphere, and that the rate of the process would depend on the rate of friction between the slabs, as well as on differential viscosity. It seems that the reduced friction in Nature was derived from the generation of serpentinites, which could be the main agent of lubrication. The underthrusting of the denser lithosphere leads to the uplift and collapse of the edge of the lighter slab, where extension, thinning, normal faulting and rifting took place, and diapiric ascent of parts of the ductile layer of the lighter slab occurred along several rifts. The analog experiments were carried out only to the stage where the denser slab was thrust under the lighter one, but the penetration of the lithosphere into the asthenosphere was not achieved. It seems plausible therefore, that only after eclogitization, and the upward motion of serpentinites, increased the density of the underthrust slab, would it dive and penetrate into the asthenosphere. The experiments indicate the plausibility of the constraints imposed on the subduction process by the deformation of the overthrust slab. The normal faults and rifts in the overthrust block could serve as conduits for the ascent of

    We study the contribution of participant and spectator matter towards different kinds of fragments. We find higher contribution of spectator matter towards heavier fragments compared to lighter fragments. We also notice that heavier IMFs preserve the time correlations. The nucleons emerging as lighter IMFs however, are well separated in the phase space at the start of the reaction and form the cluster at later times. The neutron-richness of the reacting partners is found to have negligible effect on the participant-spectator matter.

    A search is performed for a new resonance decaying into a lighter resonance and a Z boson. Two channels are studied, targeting the decay of the lighter resonance into either a pair of oppositely charged τ leptons or a b b ‾ pair. The Z boson is identified via its decays to electrons or muons. The search exploits data collected by the CMS experiment at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.8 fb-1. No significant deviations are observed from the standard model expectation and limits are set on production cross sections and parameters of two-Higgs-doublet models.

    Lighter cells from density fractionated erythrocytes of sickle cell disease (SCD) patients carry higher amount of externalized phosphatidylserine (PS) and cell surface glycophorins compared to the denser counterparts. Further analysis also revealed that the denser cells contained higher levels of fetal hemoglobin (HbF) compared to the lighter cells, supported by the presence of larger number of F-cells in these populations. In this report, we have found direct evidence on the higher survival of the HbF rich erythrocytes in SCD.

    Flexibility in residuum hydroprocessing becomes a requirement as fuel oil demand weakens, crude slates tend to be heavier, and variability in crude oil cost and supply become the norm. One means of providing flexibility is to incorporate residuum hydrotreating ahead of a heavy oil catalytic cracking unit which converts heavier components into lighter, more valuable products. Alternatively, significant conversion of the residuum to lighter products can be achieved by the operation of the residuum hydrotreater at a higher severity to facilitate hydrocracking reactions. This paper focuses on the design and selection of catalytic systems in the framework of a unified reactor modeling scheme for such residuum hydroprocessing applications.

  1. Sedimentary features on the surface of Mars as seen from Mariner 6 and 7 photographs

    NASA Technical Reports Server (NTRS)

    Parsley, R. L.

    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.

  2. Minor Corrections to Physics for Optimizing Homeland Security by Our Pal Asija

    2008-04-01

    To optimize Homeland security it must be based on correct physics. There is But ONE Reality of Physics and finding that rugged reality requires identifying and expunging erroneous knowledge. Six examples are included. *Lighter Bodies Travel Faster. (Aristotle got it backwards) *Faster Objects Become Lighter. (Einstein got it backwards) *Two Minor Corrections to Newton's First Law of Motion. *Three D or No D (Any theory based on other than 3 D is fantastic) *Gravity is A Local and Physical Contact Force *Light is never Waves and Photons at the Same Instant. These corrections are then further delineated by several examples for leading and driving innovations in homeland security.
