  3. Optimization of armored fighting vehicle crew performance in a net-centric battlefield

    NASA Astrophysics Data System (ADS)

    2002-08-01

    Traditional display, control and situational awareness technologies may not allow the fighting vehicle commander to take full advantage of the rich data environment made available in the net-centric battle field of the future. Indeed, the sheer complexity and volume of available data, if not properly managed, may actually reduce crew performance by overloading or confusing the commander with irrelevant information. New techniques must be explored to understand how to present battlefield information and provide the commander with continuous high quality situational awareness without significant cognitive overhead. Control of the vehicle's many complex systems must also be addressed the entire Soldier Machine Interface must be optimized if we are to realize the potential performance improvements. Defence Research and Development Canada (DRDC) and General Dynamics Canada Ltd. have embarked on a joint program called Future Armoured Fighting Vehicle Systems Technology Demonstrator, to explore these issues. The project is based on man-in-the-loop experimentation using virtual reality technology on a six degree-of-freedom motion platform that simulates the motion, sights and sounds inside a future armoured vehicle. The vehicle commander is provided with a virtual reality vision system to view a simulated 360 degree multi-spectrum representation of the battlespace, thus providing enhanced situational awareness. Graphic overlays with decision aid information will be added to reduce cognitive loading. Experiments will be conducted to evaluate the effectiveness of virtual control systems. The simulations are carried out in a virtual battlefield created by linking our simulation system with other simulation centers to provide a net-centric battlespace where enemy forces can be engaged in fire fights. Survivability and lethality will be measured in successive test sequences using real armoured fighting vehicle crews to optimize overall system effectiveness.

    Background Earlier age of drinking onset has been associated with greater odds of involvement in motor vehicle crashes, unintentional injuries, and physical fights after drinking. This study explores whether early drinkers take more risks even when sober by comparing potential associations between age of drinking onset and these outcomes after drinking relative to when respondents have not been drinking. Method From a national sample, 4,021 ever-drinkers ages 18 to 39 were asked age of drinking onset, not counting tastes or sips. They were also asked if they were ever in motor vehicle crashes, unintentionally injured, or in physical fights after drinking and when not drinking. GEE logistic regression models for repeated measures dichotomous outcomes compared whether odds ratios between age of onset and these adverse outcomes significantly differed when they occurred after drinking vs. when not drinking, controlling for respondents’ demographic characteristics, cigarette and marijuana use, family history of alcoholism, ever experiencing alcohol dependence, and frequency of binge drinking. Results Compared with persons who started drinking at age 21+, those who started at ages <14, 14–15, 16–17, and 18–20 had, after drinking, respectively greater odds: 6.3 (2.6, 15.3), 5.2 (2.2, 12.3), 3.3 (1.5, 7.3), and 2.2 (0.9, 5.1) of having been in a motor vehicle crash; 6.0 (3.4, 10.5), 4.9 (3.0, 8.6), 3.7 (2.4, 5.6), and 1.9 (1.2, 2.9) of ever being in a fight; and 4.6 (2.4, 8.7), 4.7 (2.6, 8.6), 3.2 (1.9, 5.6), and 2.3 (1.3, 4.0) of ever being accidentally injured. The odds of experiencing motor vehicle accidents or injuries when not drinking were not significantly elevated among early onset drinkers. The odds of earlier onset drinkers being in fights were also significantly greater when respondents had been drinking than not drinking. Conclusion Starting to drink at an earlier age is associated with greater odds of experiencing motor vehicle crash involvement

    Haskell, William E., III; Alesi, A. L.; Parsons, G. R.

    1990-01-01

    Several projects that have demonstrated the advantages of using thick composite armor technology for structural applications in armored combat vehicles are discussed. The first involved composite cargo doors for the Marine Corps LVTP-7 amphibious landing vehicle. Another was a demonstration composite turret that offered a weight reduction of 15.5 percent. The advantages of this composite armor compared to metallic armors used for combat vehicle hull and turret applications are reduced weight at equal ballistic protection; reduced back armor spall; excellent corrosion resistance; reduced production costs by parts consolidation; and inherent thermal and acoustic insulative properties. Based on the encouraging results of these past programs, the Demonstration Composite Hull Program was started in September 1986. To demonstrate this composite armor technology, the Army's newest infantry fighting vehicle, the Bradley Fighting Vehicle (BFV), was selected as a model. A composite infantry fighting vehicle, designated the CIFV for this program, has been designed and fabricated and is currently undergoing a 6000 mile field endurance test. The CIFV demonstration vehicle uses the BFV engine, transmission, suspension, track and other equipment.

  12. Bradley's Benzedrine studies on children with behavioral disorders.

    PubMed

    Strohl, Madeleine P

    2011-03-01

    In 1937, psychiatrist Charles Bradley administered Benzedrine sulfate, an amphetamine, to "problem" children at the Emma Pendleton Bradley Home in Providence, Rhode Island, in an attempt to alleviate headaches; however, Bradley noticed an unexpected effect upon the behavior of the children: improved school performance, social interactions, and emotional responses. Drawing on Bradley's published articles on his experiments, this paper explores the historical context of his experiments and the effect this background had on the emerging field of child psychiatry. Bradley's studies went largely ignored in the field of child psychiatry for nearly 25 years. However, they proved to be an important precursor to studies of amphetamines like Ritalin and their use in conditions such as attention deficit hyperactivity disorder. Bradley's Benzedrine trials were thus highly influential in shaping modern objective understandings of children with behavior disorders.

  2. Measuring Aerosols Generated Inside Armoured Vehicles Perforated by Depleted Uranium Ammunition

    SciTech Connect

    Parkhurst, MaryAnn

    2003-01-01

    In response to questions raised after the Gulf War about the health significance of exposure to depleted uranium (DU), a study was initiated to provide an improved scientific basis for assessment of possible health effects of soldiers in vehicles struck by these munitions. As part of this experimental study, a series of DU penetrators were fired at an Abrams tank and a Bradley fighting vehicle, and the aerosols generated by vehicle perforation were collected and characterized. The aerosol sampling system designed for these tests consisted of filter cassettes, cascade impactors, a five-stage cyclone, and a moving filter. Aerosols collected were analyzed for uranium concentration and particle size distribution as a function of time. The aerosol samples were also analyzed for uranium oxide phases, particle morphology, and in vitro solubility. These data will provide input for use in future prospective and retrospective dose and health risk assessments of DU aerosols.

  3. Fighting fish

    2017-01-01

    We introduce new combinatorial structures, called fighting fish, that generalize directed convex polyominoes by allowing them to branch out of the plane into independent substructures. On the one hand the combinatorial structure of fighting fish appears to be particularly rich: we show that their generating function with respect to the perimeter and number of tails is algebraic, and we conjecture a mysterious multivariate equidistribution property with the left ternary trees introduced by Del Lungo et al On the other hand, fighting fish provide a simple and natural model of random branching surfaces which displays original features: in particular, we show that the average area of a uniform random fighting fish with perimeter 2n is of order n 5/4: to the best of our knowledge this behaviour is non-standard and suggests that we have identified a new universality class of random structures.

  8. Thermal signature characteristics of vehicle/terrain interaction disturbances: implications for battlefield vehicle classification.

    PubMed

    Eastes, John W; Mason, George L; Kusinger, Alan E

    2004-05-01

    Thermal emissivity spectra (8-14 microm) of track impressions/background were determined in conjunction with operation of six military vehicle types, T-72 and M1 Tanks, an M2 Bradley Fighting Vehicle, a 5-ton truck, a D7 tractor, and a High Mobility Multipurpose Wheeled Vehicle (HMMWV), over diverse soil surfaces to determine if vehicle type could be related to track thermal signatures. Results suggest soil compaction and fragmentation/pulverization are primary parameters affecting track signatures and that soil and vehicle/terrain-contact type determine which parameter dominates. Steel-tracked vehicles exert relatively low ground-contact pressure but tend to fragment/pulverize soil more so than do rubber-tired vehicles, which tend mainly to compact. In quartz-rich, lean clay soil tracked vehicles produced impressions with spectral contrast of the quartz reststrahlen features decreased from that of the background. At the same time, 5-ton truck tracks exhibited increased contrast on the same surface, suggesting that steel tracks fragmented soil while rubber tires mainly produced compaction. The structure of materials such as sand and moist clay-rich river sediment makes them less subject to further fragmentation/pulverization; thus, compaction was the main factor affecting signatures in these media, and both tracked and wheeled vehicles created impressions with increased spectral contrast on these surfaces. These results suggest that remotely sensed thermal signatures could differentiate tracked and wheeled vehicles on terrain in many areas of the world of strategic interest. Significant applications include distinguishing visually/spectrally identical lightweight decoys from actual threat vehicles.

  12. Bradley and Lacaille: Praxis as Passionate Pursuit of Exact Science

    NASA Astrophysics Data System (ADS)

    Wilson, C. A.

    1997-12-01

    From 1700 to 1800, astronomical observation and prediction improved in accuracy by an order of magnitude or more: by century's end astronomers could trust catalogued and predicted positions to within a few arcseconds. Crucial to this improvement were the discoveries of Bradley, which grew out of an endeavor of "normal science," the attempt to confirm with precision Robert Hooke's earlier supposed discovery of annual parallax in Gamma Draconis. On the theoretical side, Bradley's discoveries led to the quiet demise of two earlier doctrines, the Tychonic System and the Aristotelian and Cartesian doctrine of the instantaneous transmission of light. On the side of praxis, Bradley's discoveries meant that observational astronomy must be re-done from the ground up. In 1742 Nicolas-Louis Lacaille (1713-62), who had been admitted to the Paris Academie des Sciences only the year before, proposed to his astronomer colleagues that they take up this task as a cooperative enterprise. His proposal met with silence, but he undertook the project on his own, making it his life's work. By 1757 he had completed his Fundamenta Astronomiae, including a catalogue of 400 bright stars in which for the first time star positions were corrected for aberration and nutation. In 1758 he published his solar tables, the first to incorporate lunar and planetary perturbations as well as aberration and nutation. Lacaille's pendulum clock was not temperature-compensated, and his sextant poorly calibrated, but he was to some extent able to compensate for these flaws by bringing a massive number of observations to bear. Till the 1790s his Fundamenta Astronomiae and Tabulae Solares were important for the increments in accuracy they brought about, and for the inspiration they gave to later astronomers such as Delambre.

  13. Diatom data from Bradley Lake, Oregon: downcore analyses

    USGS Publications Warehouse

    Hemphill-Haley, Eileen; Lewis, Roger C.

    2003-01-01

    Displaced marine diatoms provide biostratigraphic evidence for tsunami inundation at Bradley Lake, a small freshwater lake on the south-central Oregon coast. During the past 7,200 years, fine-grained lacustrine deposits in the deep axis of the lake were disturbed 17 times by the erosion and emplacement of coarse-grained gyttja and, in some cases, sand. By identifying diatoms in closely spaced core samples, we determined that 13 of the 17 events (termed idisturbance eventsi) record prehistoric tsunamis in Bradley Lake. We consider the evidence strong for 11 events, based on numbers and diversity of marine taxa: De1, De2, De4, De5, De6, De7, De8, De11, De12, De13, and De17. The evidence is less compelling for an additional 2 events (De9 and De10), although tsunami inundation is likely. Finally, we identified 4 events (De3, De14, De15 and De16) in which there were no marine diatoms to support tsunami inundation, although stratigraphic data shows that the lake bottom was disturbed. Freshwater diatoms dominate throughout the Bradley Lake record, showing that the lake has remained a freshwater habitat throughout its existence. However, anomalous occurrences of three species of brackish diatoms (Thalassiosira bramaputrae, Cyclotella meneghiniana, and Mastogloia smithii) may be evidence for short-lived periods of slightly elevated salinities in the lake following De16, De13, De12, De11, De9, De8, and De5. With the exception of De12, increased abundances of one or more of the brackish species is coincident with decreased numbers of freshwater diatoms. A temporary rise in salinity, as evidenced by short-lived increases in abundances of brackish species and decreases in abundances of freshwater species, is consistent with tsunami inundation into the lake.

  18. Measuring Aerosols Generated Inside Armoured Vehicles Perforated by Depleted Uranium Ammunition

    SciTech Connect

    Parkhurst, MaryAnn )

    2003-01-01

    In response to questions raised after the Gulf War about the health significance of exposure to depleted uranium (DU), the U.S. Department of Defense initiated a study designed to provide an improved scientific basis for assessment of possible health effects of soldiers in vehicles struck by these munitions. As part of this study, a series of DU penetrators were fired at an Abrams tank and a Bradley fighting vehicle, and the aerosols generated by vehicle perforation were collected and characterized. A robust sampling system was designed to collect aerosols in this difficult environment and to monitor continuously the sampler flow rates. Interior aerosols collected were analyzed for uranium concentration and particle size distribution as a function of time. They were also analyzed for uranium oxide phases, particle morphology, and dissolution in vitro. These data will provide input for future prospective and retrospective dose and health risk assessments of inhaled or ingested DU aerosols. This paper briefly discusses the target vehicles, firing trajectories, aerosol samplers and instrumentation control systems, and the types of analyses conducted on the samples.

  20. Stimulating a normal adjustment: misbehavior, amphetamines, and the electroencephalogram at the Bradley Home for children.

    PubMed

    Bromley, Elizabeth

    2006-01-01

    This article uses an historical case study to describe the influence of social and contextual factors on the adoption of somatic approaches to children's misbehavior. The child guidance movement and the emergence of medicalized residential treatment facilities for children influenced the theoretical orientations of physicians treating children's behavior disorders in the United States in the 1930s. Charles Bradley and his colleagues at the Bradley Home in Rhode Island defined behavior disorders in social terms but investigated and treated misbehavior with somatic tools. The use of amphetamines and the electroencephalogram reorganized concepts of maladjustment along neurological lines, even as the research relied on the Home's social priorities. Electroencephalographic investigations especially shaped an organic concept of misbehavior. Ultimately, the somatic orientation obscured the central role of local context in Bradley Home physicians' research.

    PubMed

    1993-10-07

    The U.S. Court of Appeals, Fifth Circuit, affirmed a lower court's holding that an HIV positive surgical technician, Brian Bradley, was no longer "qualified" to continue in that position within the meaning of the Rehabilitation Act of 1973. Bradley had also contended that the hospital's reassignment was retaliation against him for disclosing his HIV status to a newspaper and therefore constituted a violation of his First Amendment right of free speech. The court found that the newspaper interview was not a motivating factor in the hospital's actions. The hospital validly determined that the work of a surgical technician creates some risk of viral transmission. Although the risk of Bradley's transmitting the disease to a patient was low, the risk was not inconsequential given the possibly fatal repercussions of an accident resulting in such transmission.

  18. Systemic testing on Bradley-Terry model against nonlinear ranking hierarchy.

    PubMed

    Shev, Aaron; Fujii, Kevin; Hsieh, Fushing; McCowan, Brenda

    2014-01-01

    We take a system point of view toward constructing any power or ranking hierarchy onto a society of human or animal players. The most common hierarchy is the linear ranking, which is habitually used in nearly all real-world problems. A stronger version of linear ranking via increasing and unvarying winning potentials, known as Bradley-Terry model, is particularly popular. Only recently non-linear ranking hierarchy is discussed and developed through recognition of dominance information contents beyond direct dyadic win-and-loss. We take this development further by rigorously arguing for the necessity of accommodating system's global pattern information contents, and then introducing a systemic testing on Bradley-Terry model. Our test statistic with an ensemble based empirical distribution favorably compares with the Deviance test equipped with a Chi-squared asymptotic approximation. Several simulated and real data sets are analyzed throughout our development.

    2015-01-01

    Action recognition has become a hot topic within computer vision. However, the action recognition community has focused mainly on relatively simple actions like clapping, walking, jogging, etc. The detection of specific events with direct practical use such as fights or in general aggressive behavior has been comparatively less studied. Such capability may be extremely useful in some video surveillance scenarios like prisons, psychiatric centers or even embedded in camera phones. As a consequence, there is growing interest in developing violence detection algorithms. Recent work considered the well-known Bag-of-Words framework for the specific problem of fight detection. Under this framework, spatio-temporal features are extracted from the video sequences and used for classification. Despite encouraging results in which high accuracy rates were achieved, the computational cost of extracting such features is prohibitive for practical applications. This work proposes a novel method to detect violence sequences. Features extracted from motion blobs are used to discriminate fight and non-fight sequences. Although the method is outperformed in accuracy by state of the art, it has a significantly faster computation time thus making it amenable for real-time applications.

  2. Effect of ice formation and streamflow on salmon incubation habitat in the lower Bradley River, Alaska

    1996-01-01

    A minimum flow of 40 cubic feet per second is required in the lower Bradley River, near Homer, Alaska, from November 2 to April 30 to ensure adequate salmon egg incubation habitat. The study that determined this minimum flow did not account for the effects of ice formation on habitat. An investigation was made during periods of ice formation. Hydraulic properties and field water-quality data were measured in winter only from March 1993 to April 1995 at six transects in the lower Bradley River. Discharge in the lower Bradley River ranged from 42.6 to 73.0 cubic feet per second (average 57 cubic feet per second) with ice conditions ranging from near ice free to 100 percent ice cover. Stream water velocity and depth were adequate for habitat protection for all ice conditions and discharges. No relation was found between percent ice cover and mean velocity and depth for any given discharge and no trends were found with changes in discharge for a given ice condition. Velocity distribution within each transect varied significantly from one sampling period to the next. Mean depth and velocity at flows of 40 cubic feet per second or less could not be predicted. No consistent relation was found between the amount of wetted perimeter and percent ice cover. Intragravel-water temperature was slightly warmer than surface-water temperature. Surface and intragravel-water dissolved-oxygen levels were adequate for all flows and ice conditions. No apparent relation was found between dissolved-oxygen levels and streamflow or ice conditions. Excellent oxygen exchange was indicated throughout the study reach. Stranding potential of salmon fry was found to be low throughout the study reach. The limiting factors for determining the minimal acceptable flow limit appear to be stream-water velocity and depth, although specific limits could not be estimated because of the high flows that occurred during this study.

  3. Bradley Lake: There and Back Again, Additional Sedimentary Evidence for Earthquakes

    NASA Astrophysics Data System (ADS)

    Patton, J. R.; Goldfinger, C.

    2016-12-01

    Recurrence of southern Cascadia subduction earthquakes is constrained by stratigraphic evidence both onshore and offshore. The seismoturbidite record offshore has a higher frequency that the tsunami record in several locales. Bradley Lake (43.07°N), along the coast of southern Oregon, contains the temporally longest and highest-frequency record for paleotsunamis in Cascadia. Using additional geophysical methods, we are re-evaluating the stratigraphic record from Bradley Lake using sediment cores archived at the Oregon State University National Science Foundation Core Facility. We are interested in whether additional analysis of these cores will yield a paleoseismic record comparable to the offshore record at the same latitude. Using new CT X-Ray analyses, we use the published sedimentary facies to characterize and interpret the stratigraphic record from the lake. Using these facies interpretations and CT density-based well log correlation techniques, we correlate strata between each core and compare our results with those from the original 2005 published results and offshore cores. In addition to published facies associations, we interpret an upward fining facies found between the tsunami deposits. This facies may result from hyperpycnal flow, storm flow, sublacustrine seismo-turbidites, or inundation of tsunamis with magnitude smaller than that required to transport sediment from the dunes to the west. The return period for the additional lake turbidites and sand sheets combined is 280 years, comparable to the offshore turbidite record. The record is also potentially compatible with published tsunami models showing that some of the southernmost Cascadia earthquakes are unlikely to produce tsunami deposits in the lake. We conclude that the higher recording threshold for the Bradley Lake tsunami record is higher than that for turbidity currents and that the paleotsunami record onshore most likely comprises a subset of the offshore paleoseismic record.

    A normal mode analysis of bovine pancreatic trypsin inhibitor is carried out by using a Urey-Bradley-Shimanouchi potential energy function. The density of vibrational states, the magnitudes, and time scales of the atomic fluctuations are compared with experimental and theoretical results obtained by the more commonly used potential energy functions. The atomic fluctuations of Lys-15 are subject to extensive considerations as this residue is buried in the trypsin specificity pocket. It is found that Arg-17 is likely to be of importance in order to understand the way BPTI binds on trypsin.

    The analysis of sports data has always aroused great interest among statisticians and sports data have been investigated from different perspectives often aim at forecasting the results. The study focuses on the 12 teams who join the Malaysian Super League (MSL) for season 2015. This paper used Bayesian Expectation Maximization for Generalized Bradley Terry Model to estimate all the football team's rankings. The Generalized Bradley-Terry model is possible to find the maximum likelihood (ML) estimate of the skill ratings λ using a simple iterative procedure. In order to maximize the function of ML, we need inferential bayesian method to get posterior distribution which can be computed quickly. The team's ability was estimated based on the previous year's game results by calculating the probability of winning based on the final scores for each team. It was found that model with tie scores does make a difference in affect the model of estimating the football team's ability in winning the next match. However, team with better results in the previous year has a better chance for scoring in the next game.

    Hackley, Paul C.; Ratchford, Michael E.; Warwick, Peter D.

    2006-01-01

    Vitrinite reflectance measurements were determined for twenty-three well cuttings samples from Ashley and Bradley Counties, Arkansas, to evaluate coal rank and coalbed gas potential in the Desha Basin of the southern Missisissippi Embayment. Samples were selected from the Norman F. Williams Well Sample Library using geophysical logs to identify coaly shale and coal intervals from conventional oil and gas wells. Results indicate that maturation of vitrinite ranges from lignite to subbituminous B in the Wilcox Group (Paleocene-Eocene) at depths of 1400 to 2300 feet, and from subbituminous C to subbituminous A/high volatile bituminous C in the Trinity Group/Hosston Formation (Lower Cretaceous) at depths of 3000 to 3100 feet.

    2001-03-01

    We present a method that simplifies the refinement of force constants in normal mode calculations and makes the results more reliable. The method avoids normal mode crossings by constraining the force constants during refinement. It was tested with pyrrole, imidazole, benzene, pyridine, pyrimidine, aniline and adenine using a Urey-Bradley force field. The global error of the frequency fit for these molecules was 0.61%. The method reproduced with fewer parameters the accuracy of similar calculations of the single ring aromatic compounds. It improved the accuracy and isotopic shifts of previous empirical calculations of adenine by 40%. The C-C and C-N stretchings differed by less than 7% from the values of force constant-bond length empirical relations.

    Phakopsora pachyrhizi is a biotrophic fungus provoking SBR disease. SBR poses a major threat to global soybean production. Though several R genes provided soybean immunity to certain P. pachyrhizi races, the pathogen swiftly overcame this resistance. Therefore, fungicides are the only current means to control SBR. However, insensitivity to fungicides is soaring in P. pachyrhizi and, therefore, alternative measures are needed for SBR control. In this article, we discuss the different approaches for fighting SBR and their potential, disadvantages, and advantages over other measures. These encompass conventional breeding for SBR resistance, transgenic approaches, exploitation of transcription factors, secondary metabolites, and antimicrobial peptides, RNAi/HIGS, and biocontrol strategies. It seems that an integrating approach exploiting different measures is likely to provide the best possible means for the effective control of SBR. PMID:27375652

    It is projected that if aerospace industry interests outside of Britain fail to assume a financial and developmental role in the unmanned, airbreathing propulsion-incorporating, horizontal takeoff and landing of 'Hotol' transatmospheric vehicle for satellite launching into LEO, the entire enterprise may collapse. Hotol is an attempt to achieve launch costs only one-fifth those incurred by NASA Space Shuttle flights. Virtually all details of the Hotol powerplant and its operational cycle are secret, but it is readily understood that the use of an airbreathing, LOX-fueled phase in flight yields a weight-saving so great as to drastically reduce costs relative to nonair-breathing propulsion launch vehicles.

    Honey bee nest defense involves guard bees that specialize in olfaction-based nestmate recognition and alarm-pheromone-mediated recruitment of nestmates to sting. Stinging is influenced by visual, tactile and olfactory stimuli. Both quantitative trait locus (QTL) mapping and behavioral studies point to guarding behavior as a key factor in colony stinging response. Results of reciprocal F1 crosses show that paternally inherited genes have a greater influence on colony stinging response than maternally inherited genes. The most active alarm pheromone component, isoamyl acetate (IAA) causes increased respiration and may induce stress analgesia in bees. IAA primes worker bees for ‘fight or flight’, possibly through actions of neuropeptides and/or biogenic amines. Studies of aggression in other species lead to an expectation that octopamine or 5-HT might play a role in honey bee defensive response. Genome sequence and QTL mapping identified 128 candidate genes for three regions known to influence defensive behavior. Comparative bioinformatics suggest possible roles of genes involved in neurogenesis and central nervous system (CNS) activity, and genes involved in sensory tuning through G-protein coupled receptors (GPCRs), such as an arrestin (AmArr4) and the metabotropic GABAB receptor (GABA-B-R1).

    Based on the low detection rates of participants who incidentally encoded crime-related details in a realistic mock crime scenario, Bradley, Malik and Cullen (2011) argued that laboratory studies overestimate the validity of the Concealed Information Test. Studies from our group using naturalistic mock crime scenarios, multiple physiological response measures and improved scoring and classification techniques suggest that such a general conclusion is not warranted.

    Lee Carrington Bradley's career as a physicist began as an accomplished student at Phillips Exeter Academy, where he was influenced by Professor John C. Hogg, chairman of the Science Department. He graduated in 1943 and entered the V-12 program for naval officers and completed his undergraduate degree in physics at Princeton University. After a brief tour as a Navy Ensign he joined the first group of American Rhodes Scholars to attend Oxford University, in 1947, following the conclusion of World War II. Under the guidance of H.G. Kuhn of Clarendon Laboratory, Lee completed his Ph.D. in physics in 1950. He then accepted an instructorship in physics at Princeton until he was called to MIT as an assistant professor in 1954 and later as a research associate in the Harrison Spectroscopy Laboratory. In 1966 he joined the technical staff of MIT Lincoln Laboratory, and became a senior staff member in 1978, a position he held until his retirement in 1992. From 1947 to 1966 Lee's interest was primarily in the field of optical spectroscopy, where his work brought him into contact with many of the outstanding physicists of his era. Upon joining Lincoln Laboratory, his physics interests shifted toward optics and laser propagation, the latter a field in which he made significant contributions. My illustrated tribute will discuss Lee's passage from Phillips Exeter to Lincoln Laboratory, describing his physics and some of the notable physicists with whom he worked.

    Contests among individuals over mating opportunities are common across diverse taxa, yet physical conflict is relatively rare. Due to the potentially fatal consequences of physical fighting, most animals employ mechanisms of conflict resolution involving signalling and ritualistic assessment. Here we provide the first evidence of ubiquitous escalated fighting in grasshoppers. The chameleon grasshopper (Kosciuscola tristis) is an Australian alpine specialist, in which males engage in highly aggressive combat over ovipositing females. We describe discrete agonistic behaviours including mandible flaring, mounting, grappling, kicking and biting, and their use depending on the individual's role as challenger or defender. We show that male role predicts damage, with challengers being more heavily damaged than males defending females (defenders). Challengers also possess wider mandibles than defenders, but are similar in other metrics of body size. Our data suggest that fights escalate between males matched in body size and that mandibles are used as weapons in this species. This system represents an exciting opportunity for future research into the evolution of costly fighting behaviour in an otherwise placid group.

    2014-01-01

    Objective Identify risk factors for fighting, factors that protect against fighting, and strategies to prevent fighting, among adolescents who fight and those uninvolved in fighting. Methods Focus groups were conducted with middle and high-school students, stratified by fighting (fighter/non-fighter) status, race/ethnicity, and gender. Groups were audiotaped, transcribed, and analyzed using margin coding and thematic content analysis. Themes were independently identified by three coders; disagreements were resolved by consensus. Results The 65 participants in the 12 focus groups were 13–17 years old. Reasons for fighting include self-defense, to gain/maintain respect, or due to anger; having goals for the future is protective. Non-fighters state that their parents condone fighting only when physically attacked, and teach adolescents strategies to avoid fighting. Fighters describe mixed messages from parents, and pro-fighting attitudes and modeling of aggressive behavior among some family members. Non-fighters avoid fighting by ignoring insults or walking away. Fighters feel unable to use nonviolent conflict-resolution methods effectively. Peers may instigate or encourage fights. Suggested prevention strategies include anger-management and conflict-resolution programs, relationships with caring adults, and physicians counseling youth about the consequences of fighting. Conclusions Non-fighters use various strategies to avoid fighting, whereas fighters are aware of few alternatives to fighting. Conflicting parental messages about fighting may enhance the likelihood of fighting. Physicians can counsel youth about the negative consequences of fighting. Interventions that teach anger management and conflict resolution, promote adolescent self-efficacy for using non-violent strategies, and address parental attitudes about fighting may be effective in preventing fighting.

    During the years 1714 to 1721, Richard Bradley, who was later to become the first Professor of Botany at Cambridge University, proposed a unified, unique, living agent theory of the cause of infectious diseases of plants and animals and the plague of humans. Bradley's agents included microscopic organisms, revealed by the studies of Robert Hooke and Antony van Leeuwenhoek. His theory derived from his experimental studies of plants and their diseases and from microscopic observation of animalcules in different naturally occurring and artificial environments. He concluded that there was a microscopic world of "insects" that lived and reproduced under the appropriate conditions, and that infectious diseases of plants were caused by such "insects." Since there are structural and functional similarities between plants and animals, Bradley concluded that microscopic organisms caused human and animal infectious diseases as well. However, his living agent cause of infectious diseases was not accepted by the contemporary scientific society.

    Plasma concentrations of pituitary adrenocorticotrophic hormone (ACTH) and adrenocortical steroids in rats after testing in the shock-induced fighting paradigm were examined. The investigations provide data consistent with the view that psychological aspects of the stressful situation are important in determining the effects of shock on physiological function. The data indicate that the pituitary-adrenal response can be attenuated by the expression of an organized pattern of behavior.

    Immunotherapies constitute an important trend in developing new cancer treatments, and several promising candidates are under evaluation in clinical trials. Plants have entered the fight against cancer because they constitute low-cost and efficient hosts for biopharmaceutical production that can also serve as oral delivery vehicles. This review is focused on the knowledge gained through the development of anticancer plant-made vaccines reported thus far, and highlights the potential of this technology - its success being reflected in the number of candidates that are close to market. Future prospects for anticancer plant-made vaccines are also identified. Copyright © 2016 Elsevier Ltd. All rights reserved.

  1. The Hospital for the Ruptured and Crippled: William Bradley Coley, Third Surgeon-in-Chief 1925–1933

    PubMed Central

    2007-01-01

    In January 1925, the Board of Managers of the New York Society for the Relief of the Ruptured and Crippled appointed William Bradley Coley, M.D., age 63, Surgeon-in-Chief of the Hospital for the Ruptured and Crippled (R & C) to succeed Virgil P. Gibney who submitted his resignation the month before. It would be the first time a general surgeon held that position at the oldest orthopedic hospital in the nation, now known as Hospital for Special Surgery (HSS). Coley had been on staff for 36 years and was world famous for introducing use of toxins to treat malignant tumors, particularly sarcomas. A graduate of Yale College and Harvard Medical College, Coley interned at New York Hospital and was appointed, soon after, to the staff of the New York Cancer Hospital (now Memorial Sloan Kettering Cancer Center) located at that time at 106th Street on the West Side of New York. With his mentor Dr. William Bull, Coley perfected the surgical treatment of hernias at R & C. He was instrumental in raising funds for his alma maters, Yale, Harvard and Memorial Hospital. His crusade in immunology as a method of treatment for malignant tumors later fell out of acceptance in the medical establishment. After his death in 1936, an attempt to revive interest in use of immunotherapy for inoperable malignancies was carried out by his daughter, Helen Coley Nauts, who pursued this objective until her death at age 93 in 2000. Coley’s health deteriorated in his later years, and in 1933, he resigned as chief of Bone Tumors at Memorial Hospital and Surgeon-in-Chief at R & C, being succeeded at Ruptured and Crippled as Surgeon-in-Chief by Dr. Eugene H. Pool. William Bradley Coley died of intestinal infarction in 1936 and was buried in Sharon, Connecticut. PMID:18751855

  5. How to fight antimicrobial resistance.

    PubMed

    Foucault, Cédric; Brouqui, Philippe

    2007-03-01

    Antimicrobial misuse results in the development of resistance and superbugs. Over recent decades, resistance has been increasing despite continuing efforts to control it, resulting in increased mortality and cost. Many authorities have proposed local, regional and national guidelines to fight against this phenomenon, and the usefulness of these programmes has been evaluated. Multifaceted intervention seems to be the most efficient method to control antimicrobial resistance. Monitoring of bacterial resistance and antibiotic use is essential, and the methodology has now been homogenized. The implementation of guidelines and infection control measures does not control antimicrobial resistance and needs to be reinforced by associated measures. Educational programmes and rotation policies have not been evaluated sufficiently in the literature. Combination antimicrobial therapy is inefficient in controlling antimicrobial resistance.

    Parasites are ubiquitous, and the ability to defend against these is of paramount importance. One way to fight diseases is self-medication, which occurs when an organism consumes biologically active compounds to clear, inhibit, or alleviate disease symptoms. Here, we show for the first time that ants selectively consume harmful substances (reactive oxygen species, ROS) upon exposure to a fungal pathogen, yet avoid these in the absence of infection. This increased intake of ROS, while harmful to healthy ants, leads to higher survival of exposed ants. The fact that ingestion of this substance carries a fitness cost in the absence of pathogens rules out compensatory diet choice as the mechanism, and provides evidence that social insects medicate themselves against fungal infection, using a substance that carries a fitness cost to uninfected individuals.

    A common feature of animal populations is the stealing by animals of resources such as food from other animals. This has previously been the subject of a range of modelling approaches, one of which is the so called "producer-scrounger" model. In this model a producer finds a resource that takes some time to be consumed, and some time later a (generally) conspecific scrounger discovers the producer with its resource and potentially attempts to steal it. In this paper we consider a variant of this scenario where each individual can choose to invest an amount of energy into this contest, and the level of investment of each individual determines the probability of it winning the contest, but also the additional cost it has to bear. We analyse the model for a specific set of cost functions and maximum investment levels and show how the evolutionarily stable behaviour depends upon them. In particular we see that for high levels of maximum investment, the producer keeps the resource without a fight for concave cost functions, but for convex functions the scrounger obtains the resource (albeit at some cost).

    Fighting detection is an important issue in security aimed to prevent criminal or undesirable events in public places. Many researches on computer vision techniques have studied to detect the specific event in crowded scenes. In this paper we focus on fighting detection using social-based Interaction Energy Force (IEF). The method uses low level features without object extraction and tracking. The interaction force is modeled using the magnitude and direction of optical flows. A fighting factor is developed under this model to detect fighting events using thresholding method. An energy map of interaction force is also presented to identify the corresponding events. The evaluation is performed using NUSHGA and BEHAVE datasets. The results show the efficiency with high accuracy regardless of various conditions.

    Two new yeast species, Cryptococcus bestiolae and Cryptococcus dejecticola, were discovered in the frass of the litchi fruit borer Conopomorpha sinensis Bradley. The yeasts utilize inositol, hydrolyze urea, produce starch-like substance, and contain CoQ10. Phylogenetic analyses of D1/D2 26S rDNA and internal transcribed spacer (ITS) sequences indicate that the yeasts are closely related to Bullera dendrophila and an undescribed species of Cryptococcus (strain CBS 8507). The two new species differed from each other by 17 nucleotides in the D1/D2 region and by 68 nucleotides in the ITS region. Cryptococcus bestiolae is a sister species to Cryptococcus sp. CBS 8507, from which it differs by eight nucleotides in the D1/D2 region and 59 nucleotides in the ITS region. Cryptococcus dejecticola and B. dendrophila differed by 13 nucleotides in the D1/D2 and 57 nucleotides in the ITS region. Cryptococcus bestiolae and Cr. dejecticola formed with B. dendrophila a well defined clade consisting of insect associated species. The type strain of Cr. bestiolae is TH3.2.59 (=CBS 10118=NRRL Y-27894), and the type strain of Cr. dejecticola is Litch 17 (=CBS 10117=NRRL Y-27898).

  16. Biocatalytic nerve agent detoxification in fire fighting foams.

    PubMed

    LeJeune, K E; Russell, A J

    1999-03-20

    Current events across the globe necessitate rapid technological advances to combat the epidemic of nerve agent chemical weapons. Biocatalysis has emerged as a viable tool in the detoxification of organophosphorus neurotoxins, such as the chemical weapons VX and sarin. Efficient detoxification of contaminated equipment, machinery, and soils are of principal concern. This study describes the incorporation of a biocatalyst (organophosphorus hydrolase, E.C. 3.1.8.1) into conventional formulations of fire fighting foam. The capacity of fire fighting foams to decrease volatilization of contained contaminants, increase surface wettability, and control the rate of enzyme delivery to large areas makes them useful vehicles for enzyme application at surfaces. The performance of enzyme containing foams has been shown to be not only reproducible but also predictable. An empirical model provides reasonable estimations for the amounts of achievable surface decontamination as a function of the important parameters of the system. Theoretical modeling illustrates that the enzyme-containing foam is capable of extracting agent from the surface and is catalytically active at the foam-surface interface and throughout the foam itself. Biocatalytic foam has proven to be an effective, "environmentally friendly" means of surface and soil decontamination.

  1. Fighting for shells: how private information about resource value changes hermit crab pre-fight displays and escalated fight behaviour.

    PubMed

    Arnott, Gareth; Elwood, Robert W

    2007-12-07

    Pre-fight displays typically provide honest, but sometimes dishonest, information about resource holding potential and may be influenced by assessment of resource value and hence motivation to acquire the resource. These assessments of potential costs and benefits are also predicted to influence escalated fight behaviour. This is examined in shell exchange contests of hermit crabs in which we establish an information asymmetry about a particularly poor quality shell. The poor shell was created by gluing sand to the interior whereas control shells lacked sand and the low value of the poor shell could not be accurately assessed by the opponent. Crabs in the poor shell showed changes in the use of pre-fight displays, apparently to increase the chances of swapping shells. When the fights escalated, crabs in poor shells fought harder if they took the role of attacker but gave up quickly if in the defender role. These tactics appear to be adaptive but do not result in a major shift in the roles taken or outcome. We thus link resource assessment with pre-fight displays, the roles taken, tactics used during escalation and the outcome of these contests.

    Around the world, there are an estimated 300,000 to 500,000 children involved in armed conflict. Children can be abducted into a fighting force to fight or serve as sex slaves. Child soldiers have depression, anxiety, and posttraumatic stress symptoms; however, evidence is mixed because of methodologic limitations. Various mental health interventions have been tried, with promising results. Child and adolescent psychiatrists are uniquely trained in understanding and assisting youth to heal from such extraordinary experiences. A public health paradigm could include interventions that are based on a comprehensive assessment of interweaving developmental, biological, psychological, and sociocultural factors.

    In animals, correlations exist among behaviors within individuals, but it is unclear whether experience in a specific functional context can affect behavior across different contexts. Here, we use Drosophila melanogaster to investigate the effects of conflict-induced behavioral modifications on male mating behavior. In D. melanogaster, males fight for territories and experience a strong winner-loser effect, meaning that winners become more likely to win subsequent fights compared to losers, who continue to lose. In our protocol, males were tested for courtship intensity before and after fighting against other males. We show that male motivation to copulate before fights cannot predict the fight outcomes, but that, afterwards, losers mate less than before and less than winner and control males. Contrarily, winners show no differences between pre- and post-fight courtship intensity, and do not differ from control males. This suggests that the physiological modifications resulting from fight outcomes indirectly affect male reproductive behavior.

    2016-11-11

    In competition for food, territory and mates, male fruit flies (Drosophila melanogaster) engage in agonistic encounters with conspecifics. The fighting strategies used to obtain these resources are influenced by previous and present experience, environmental cues, and the internal state of the animal including hormonal and genetic influences. Animals that experience prior defeats show submissive behavior and are more likely to lose 2(nd) contests, while animals that win 1(st) fights are more aggressive and have a higher probability of winning 2(nd) contests. In a recent report, we examined these loser and winner effects in greater detail and demonstrated that both winners and losers show short-term memory of the results of previous bouts while only losers demonstrate a longer-term memory that requires protein synthesis. The recent findings also suggested that an individual recognition mechanism likely exists that can serve important roles in evaluating the fighting ability of opponents and influencing future fighting strategy. In this article, we follow up on these results by asking how previous defeated and victorious flies change their fighting strategies in the presence of 2(nd) losing and winning flies, by searching for evidence of territory marking, and discussing the existing literature in light of our findings.

  18. How to pick a good fight.

    Peace and harmony are overrated. Though conflict-free teamwork is often held up as the be-all and end-all of organizational life, it actually can be the worst thing to ever happen to a company. Look at Lehman Brothers. When Dick Fuld took over, he transformed a notoriously contentious workplace into one of Wall Street's most harmonious firms. But his efforts backfired--directors and managers became too agreeable, afraid to rock the boat by pointing out that the firm was heading into a crisis. Research shows that the single greatest predictor of poor company performance is complacency, which is why every organization needs a healthy dose of dissent. Not all kinds of conflict are productive, of course -companies need to find the right balance of alignment and competition and make sure that people's energies are pointed in a positive direction. In this article, two seasoned business advisers lay down ground rules for the right kinds of fights. First, the stakes must be worthwhile: The issue should involve a noble purpose or create noticeable--preferably game-changing--value. Next, good fights focus on the future; they're never about placing blame for the past. And it's critical for leaders to keep fights sportsmanlike, allow informal give-and-take in the trenches, and help soften the blow for the losing parties.

  19. Coal Field Fire Fighting - Practiced methods, strategies and tactics

    Subsurface coal fires destroy millions of tons of coal each year, have an immense impact to the ecological surrounding and threaten further coal reservoirs. Due to enormous dimensions a coal seam fire can develop, high operational expenses are needed. As part of the Sino-German coal fire research initiative "Innovative technologies for exploration, extinction and monitoring of coal fires in Northern China" the research team of University of Wuppertal (BUW) focuses on fire extinction strategies and tactics as well as aspects of environmental and health safety. Besides the choice and the correct application of different extinction techniques further factors are essential for the successful extinction. Appropriate tactics, well trained and protected personnel and the choice of the best fitting extinguishing agents are necessary for the successful extinction of a coal seam fire. The chosen strategy for an extinction campaign is generally determined by urgency and importance. It may depend on national objectives and concepts of coal conservation, on environmental protection (e.g. commitment to green house gases (GHG) reductions), national funding and resources for fire fighting (e.g. personnel, infrastructure, vehicles, water pipelines); and computer-aided models and simulations of coal fire development from self ignition to extinction. In order to devise an optimal fire fighting strategy, "aims of protection" have to be defined in a first step. These may be: - directly affected coal seams; - neighboring seams and coalfields; - GHG emissions into the atmosphere; - Returns on investments (costs of fire fighting compared to value of saved coal). In a further step, it is imperative to decide whether the budget shall define the results, or the results define the budget; i.e. whether there are fixed objectives for the mission that will dictate the overall budget, or whether the limited resources available shall set the scope within which the best possible results shall be

  20. Fighting like a girl fighting like a guy: gender identity, ideology, and girls at early adolescence.

    2008-01-01

    In this chapter we explore the phenomenon of "girls fighting like guys" by listening to adolescent girls' justification for physical fighting with other girls. We argue that physical girlfighting is a particular kind of gendered performance--a performance of identity that expresses, at least in part, an answer to the question, "Who am I?"--that both perpetuates and challenges the usual notions of masculinity and femininity and the differential power associated with these discourses. We present a sociocultural approach to identity that we believe not only holds promise for helping us to understand girl-fighting behavior but also highlights the clear interrelationship between social identity and personal identity. We conclude by highlighting several implications of this analysis for those who work with girls (and boys) in educational and clinical settings.

    In recent years, there has been a huge increase in the number of bots online, varying from Web crawlers for search engines, to chatbots for online customer service, spambots on social media, and content-editing bots in online collaboration communities. The online world has turned into an ecosystem of bots. However, our knowledge of how these automated agents are interacting with each other is rather poor. Bots are predictable automatons that do not have the capacity for emotions, meaning-making, creativity, and sociality and it is hence natural to expect interactions between bots to be relatively predictable and uneventful. In this article, we analyze the interactions between bots that edit articles on Wikipedia. We track the extent to which bots undid each other's edits over the period 2001-2010, model how pairs of bots interact over time, and identify different types of interaction trajectories. We find that, although Wikipedia bots are intended to support the encyclopedia, they often undo each other's edits and these sterile "fights" may sometimes continue for years. Unlike humans on Wikipedia, bots' interactions tend to occur over longer periods of time and to be more reciprocated. Yet, just like humans, bots in different cultural environments may behave differently. Our research suggests that even relatively "dumb" bots may give rise to complex interactions, and this carries important implications for Artificial Intelligence research. Understanding what affects bot-bot interactions is crucial for managing social media well, providing adequate cyber-security, and designing well functioning autonomous vehicles.

    2014-01-01

    The vibrational frequencies of the disaccharide isomaltulose in the solid state have been reproduced in the 50-4000 cm-1 range. The modified Urey-Bradley-Shimanouchi force field was used, combined with an inter molecular potential energy function that includes van der Waals interactions, electrostatic terms, and an explicit hydrogen bond function. The force constants previously established for α-D-glucopyranose and β-D-fructo pyranose, as well as the crystallographic data of isomaltulose monohydrate, were the starting parameters for the present work. The vibrational frequencies of isomaltulose were calculated and assigned to the experimentally observed vibrational frequencies. Overall, there was good agreement between the observed and calculated frequencies with an average error of 4 cm-1. Furthermore, good agreement was found between our calculated results and the vibration spectra of other disaccharides and monosaccharides.

    1999-01-01

    This paper describes an Integrated Vehicle Modeling Environment for estimating aircraft geometric, inertial, and aerodynamic characteristics, and for interfacing with a high fidelity, workstation based flight simulation architecture. The goals in developing this environment are to aid in the design of next generation intelligent fight control technologies, conduct research in advanced vehicle interface concepts for autonomous and semi-autonomous applications, and provide a value-added capability to the conceptual design and aircraft synthesis process. Results are presented for three aircraft by comparing estimates generated by the Integrated Vehicle Modeling Environment with known characteristics of each vehicle under consideration. The three aircraft are a modified F-15 with moveable canards attached to the airframe, a mid-sized, twin-engine commercial transport concept, and a small, single-engine, uninhabited aerial vehicle. Estimated physical properties and dynamic characteristics are correlated with those known for each aircraft over a large portion of the flight envelope of interest. These results represent the completion of a critical step toward meeting the stated goals for developing this modeling environment.

  10. Male Weaponry in a Fighting Cricket

    Sexually selected male weaponry is widespread in nature. Despite being model systems for the study of male aggression in Western science and for cricket fights in Chinese culture, field crickets (Orthoptera, Gryllidae, Gryllinae) are not known to possess sexually dimorphic weaponry. In a wild population of the fall field cricket, Gryllus pennsylvanicus, we report sexual dimorphism in head size as well as the size of mouthparts, both of which are used when aggressive contests between males escalate to physical combat. Male G. pennsylvanicus have larger heads, maxillae and mandibles than females when controlling for pronotum length. We conducted two experiments to test the hypothesis that relatively larger weaponry conveys an advantage to males in aggressive contests. Pairs of males were selected for differences in head size and consequently were different in the size of maxillae and mandibles. In the first experiment, males were closely matched for body size (pronotum length), and in the second, they were matched for body mass. Males with proportionately larger weaponry won more fights and increasing differences in weaponry size between males increased the fighting success of the male with the larger weaponry. This was particularly true when contests escalated to grappling, the most intense level of aggression. However, neither contest duration nor intensity was related to weaponry size as predicted by models of contest settlement. These results are the first evidence that the size of the head capsule and mouthparts are under positive selection via male-male competition in field crickets, and validate 800-year-old Chinese traditional knowledge.

    The seal is a lightweight, inflatable, bag which may be inflated by a portable air generator and is used to seal a burning mine passage. A collapsible tube-like aperture extends through the seal and allows passage of high expansion foam through the seal in a feed tube. The foam fills the passageway and extinguishes the fire. In other embodiments, the feed tubes incorporate means to prevent collapse of the aperture. In these embodiments a shroud connects the feed tube to a foam generator. This seal allows creation of a high expansion foam fire fighting barrier even in upward sloping passages.

    2015-01-01

    Stevia is a natural, non-caloric sweetener of plant origin. The sweetening power of stevia is several hundred times larger than that of table sugar (sucrose). On the basis of available research, the European Food Safety Authority concluded that stevia is safe for human consumption. Since then, stevia has been approved as a sweetener for the European market. As a substitute for sucrose, stevia can contribute to a reduced caloric intake and can play a role in the prevention and/or treatment of metabolic disorders. In addition, stevia is non-cariogenic and is, moreover, affordable. Promoting the consumption of stevia can therefore be a preventive means of fighting dental caries.

    2014-09-01

    Enveloped viruses pose an important health threat because most of the persistent and many emerging viruses are enveloped. In particular, newly emerging viruses create a need to develop broad-spectrum antivirals, which usually are obtained by targeting host cell factors. Persistent viruses have developed efficient strategies to escape host immune control, and treatment options are limited. Targeting host cell factors essential for virus persistence, or immune-based therapies provide alternative approaches. In this review, we therefore focus on recent developments to generate antivirals targeting host cell factors or immune-based therapeutic approaches to fight infections with enveloped viruses.

    Phytochemicals are chemical compounds from fruits, vegetables, or grains and they have been used to treat various diseases for thousands of years. More than one million people in the United States get cancer each year. Although recent advances in medicine have improved the outcomes for cancer patients, there is still a need for novel approaches in the fight against cancer. One such approach that has shown promise in recent years is the use of phytochemicals alone or as synergistic agents. In this review, we will discuss the use of phytochemicals as therapeutic agents against cancer with an emphasis on apple extract.

    Quiet, clean, and efficient, electric vehicles (EVs) may someday become a practical mode of transportation for the general public. Electric vehicles can provide many advantages for the nation's environment and energy supply because they run on electricity, which can be produced from many sources of energy such as coal, natural gas, uranium, and hydropower. These vehicles offer fuel versatility to the transportation sector, which depends almost solely on oil for its energy needs. Electric vehicles are any mode of transportation operated by a motor that receives electricity from a battery or fuel cell. EVs come in all shapes and sizes and may be used for different tasks. Some EVs are small and simple, such as golf carts and electric wheel chairs. Others are larger and more complex, such as automobile and vans. Some EVs, such as fork lifts, are used in industries. In this fact sheet, we will discuss mostly automobiles and vans. There are also variations on electric vehicles, such as hybrid vehicles and solar-powered vehicles. Hybrid vehicles use electricity as their primary source of energy, however, they also use a backup source of energy, such as gasoline, methanol or ethanol. Solar-powered vehicles are electric vehicles that use photovoltaic cells (cells that convert solar energy to electricity) rather than utility-supplied electricity to recharge the batteries. This paper discusses these concepts.

    2014-03-01

    Resurgence of previously reinforced responding was investigated in male Siamese fighting fish (Betta splendens). Swimming through a ring produced 15-s mirror presentations according to, with different fish, either a fixed-ratio 1 or a variable-interval 60-s schedule of reinforcement. When responding was stable, a differential-reinforcement-of-other-behavior schedule was substituted for the mirror-presentation schedule. Following this, mirror presentations were discontinued (extinction). During this latter phase, there were transient increases in the ring-swim response relative to the frequency of such responding during the differential-reinforcement-of-other behavior schedule. Resurgence was similar for the fish exposed previously to the fixed-ratio or to the variable-interval schedule. These results extend to Siamese fighting fish a well-established behavioral phenomenon previously not observed in this species or with this response topography, and only rarely reported following the removal of a non-consumable reinforcer.

    2004-01-01

    Objectives: To assess youth perceptions of the causes and consequences of violence generally, the causes and consequences of fighting specifically, and to determine how best to approach fighting in the context of violence prevention activities. Methods: Thirteen structured focus group interviews with youths from three high violence urban settings: a large, urban high school, a training center for disadvantaged youths, and a school for adjudicated youths. Participants were 120 urban, predominately African-American youths and young adults ages 14–22 years (mean: 17.2 years). Seven focus groups were conducted with females, and six with males. Results: Adolescents identified the causes of violence on multiple levels including: individual, family, interpersonal, and community level factors. Most youths (89%) had been in a physical fight. Participants felt that fighting was not "right", but identified situations in which it was necessary. Specifically, fighting was used as a problem solving tool, and could prevent escalation of violence. Youths felt that the adults in their lives, including physicians, were generally ill equipped to give advice about violence, as adults' experiences were so removed from their own. Participants looked to experienced role models to offer problem solving and harm reduction strategies. Youths were open to receiving anticipatory guidance about violence and fighting from primary care physicians they felt comfortable with, and who showed respect for their experiences. Conclusions: Interventions that include blanket admonitions against fighting should be reassessed in light of youth perceptions that fighting plays a complex role in both inciting and preventing more serious violence.

  1. Structural adaptations to diverse fighting styles in sexually selected weapons

    PubMed Central

    McCullough, Erin L.; Tobalske, Bret W.; Emlen, Douglas J.

    2014-01-01

    The shapes of sexually selected weapons differ widely among species, but the drivers of this diversity remain poorly understood. Existing explanations suggest weapon shapes reflect structural adaptations to different fighting styles, yet explicit tests of this hypothesis are lacking. We constructed finite element models of the horns of different rhinoceros beetle species to test whether functional specializations for increased performance under species-specific fighting styles could have contributed to the diversification of weapon form. We find that horns are both stronger and stiffer in response to species-typical fighting loads and that they perform more poorly under atypical fighting loads, which suggests weapons are structurally adapted to meet the functional demands of fighting. Our research establishes a critical link between weapon form and function, revealing one way male–male competition can drive the diversification of animal weapons. PMID:25201949

  2. Launch vehicle

    1994-06-01

    Concentrated efforts by NASA and the DOD to begin development of a new large launch vehicle have been under way for over a decade. Options include the National Launch System, Advanced Launch System, a heavy lift vehicle, a Shuttle-derived vehicle, a Titan-derived vehicle, Single stage To Orbit, NASP and Spacelifter, to name a few. All initially promised low operations costs achieved at development costs in the $5 billion - $10 billion range. However, none has obtained approval for development, primarily because it became apparent that these cost goals could not realistically be met.

    1996-07-01

    The U.S. Army Field Assistance Science and Technology Program requested Oak Ridge National Laboratory (ORNL) to demonstrate the use of lightweight composite materials in construction of overhead covers for reinforced infantry fighting positions. In recent years, ORNL researchers have designed and tested several concepts for lightweight ballistic protection structures, and they have developed numerous prototype composite structures for military and civilian applications. In the current program, composite panel designs and materials are tested and optimized to meet anticipated static and dynamic load conditions for the overhead cover structure. Ten prototype composite covers were built at ORNL for use in Army field tests. Each composite cover has a nominal surface area of 12 ft[sup 2] and a nominal weight of 8 lb. Four of the prototypes are made with folding sections to improve their handling characteristics. The composite covers exhibit equivalent performance in Army field tests to covers made with conventional materials that weigh four times as much.

  4. Building an Intelligent Hospital to Fight Contagion.

    The idea of building hospitals to fight contagion was born with the lazarettos. At the time when the microorganisms were not yet known, the mechanisms of transmission of contagion were already well apprehended. Based on the same knowledge but thanks to new technologies, such hospitals have now been built downtown, next to the most highly performing technological plateau. Regrouping patient care, diagnostics, research, and development, the University Hospital Institute Méditerranée Infection building offers a wonderful tool to contain and understand contagion, in a well-designed setting, creating excellent working conditions that are attractive for interested scientists. © The Author 2017.

  7. Fighting HIV/AIDS: is success possible?

    PubMed Central

    Okware, S.; Opio, A.; Musinguzi, J.; Waibale, P.

    2001-01-01

    The fight against HIV/AIDS poses enormous challenges worldwide, generating fears that success may be too difficult or even impossible to attain. Uganda has demonstrated that an early, consistent and multisectoral control strategy can reduce both the prevalence and the incidence of HIV infection. From only two AIDS cases in 1982, the epidemic in Uganda grew to a cumulative 2 million HIV infections by the end of 2000. The AIDS Control Programme established in 1987 in the Ministry of Health mounted a national response that expanded over time to reach other relevant sectors under the coordinating role of the Uganda AIDS Commission. The national response was to bring in new policies, expanded partnerships, increased institutional capacity for care and research, public health education for behaviour change, strengthened sexually transmitted disease (STD) management, improved blood transfusion services, care and support services for persons with HIV/AIDS, and a surveillance system to monitor the epidemic. After a decade of fighting on these fronts, Uganda became, in October 1996, the first African nation to report declining trends in HIV infection. Further decline in prevalence has since been noted. The Medical Research Council (UK) and the Uganda Virus Research Institute have demonstrated declining HIV incidence rates in the general population in the Kyamulibwa in Masaka Districts. Repeat knowledge, attitudes, behaviour and practice studies have shown positive changes in the priority prevention indicators. The data suggest that a comprehensive national response supported by strong political commitment may be responsible for the observed decline. Other countries in sub-Saharan Africa can achieve similar results by these means. Since success is possible, anything less is unacceptable. PMID:11799443

  8. To breathe or fight? Siamese fighting fish differ when facing a real opponent or mirror image.

    PubMed

    Arnott, Gareth; Beattie, Emma; Elwood, Robert W

    2016-08-01

    Displays are a feature of animal contest behaviour and have been interpreted as a means of gathering information on opponent fighting ability, as well as signalling aggressive motivation. In fish, contest displays often include frontal and lateral elements, which in the latter involves contestants showing their flanks to an opponent. Previous work in a range of fish species has demonstrated population-level lateralization of these displays, preferentially showing one side to their opponent. Mirrors are commonly used in place of a real opponent to study aggression in fish, yet they may disrupt the normal pattern of display behaviour. Here, using Siamese fighting fish, Betta splendens, we compare the aggressive behaviour of males to a mirror image and real opponent behind a transparent barrier. As this species is a facultative air-breather, we also quantify surface breathing, providing insights into underlying fight motivation. Consistent with previous work, we found evidence of population-level lateralization, with a bias to present the left side and use the left eye when facing a real opponent. Contrary to expectations, there were no differences in the aggressive displays to a mirror and real opponent, with positive correlations between the behaviour in the two scenarios. However, there were important differences in surface breathing, which was more frequent and of longer duration in the mirror treatment. The reasons for these differences are discussed in relation to the repertoire of contest behaviour and motivation when facing a real opponent.

  6. Fighting desires: Henry Miller's Queer Tropic.

    PubMed

    Hardin, Michael

    2002-01-01

    "Fighting Desires: Henry Miller's Queer Tropic" is an investigation of Tropic of Cancer that investigates the deeply repressed homoerotic desire that periodically surfaces. This reading is dependent upon an interpretation of Eve Sedgwick that proposes male sexuality as a continuum. By looking at the nature of the male-male relationships, as well as the lack of emotion and presence in the male-female relationships, I will show that the most intimate relationships are between men, and that these relationships are expressed through the telling of stories about (heterosexual) sex; this is the function of women within the novel: one has sex with a woman, not for the pleasure that the act brings, but for the pleasure that the recounting of the story to other men brings. Furthermore, I will look at Miller's use of puns within the novel and how they also contribute to a homoerotic reading. None of this is to argue that Miller was not homophobic and sexist--Miller very clearly was--the purpose of this essay is to show the complex nature of sexuality, even within a protagonist who asserts a very defined heterosexuality.

  7. Microcredit -- an emerging tool for fighting poverty.

    PubMed

    1997-01-01

    A summit focusing on microcredit (small business, microenterprise, loans) as a means of fighting poverty was held February 3-4 in Washington; it was co-chaired by First Lady Hillary Rodham Clinton and by Queen Sofia of Spain. The United States Agency for International Development (USAID) has long supported microenterprise and microfinance. The summit set a goal of reaching 100 million poor families over the next nine years. USAID Administrator Brian Atwood spoke concerning the need to involve the private sector in microfinance; previously loans had been financed outside of the mainstream financial system via nongovernmental organizations and credit unions funded mainly by governments and donors. USAID launched a Microenterprise Initiative in 1994 that has supported 150 programs in 45 countries, and that is expected to reach approximately 4 million families. Atwood said the microenterprise strategies were currently in use in nearly every country USAID supports in Latin America and Asia, and most countries in Africa; future efforts would concentrate on countries in Africa, in eastern Europe and in central Asia. Mrs. Clinton called microenterprise "an invaluable tool in alleviating poverty, promoting self-sufficiency, and stimulating the economy." Treasury Secretary Robert Rubin stated that the policy helped people help themselves by giving them the tools they needed to join the economic mainstream. Microcredit focuses on businesses with five or fewer workers; loans range from less than $100 to $10,000. More than half of the businesses are owned and operated by women.

  8. Antimicrobial Drugs in Fighting against Antimicrobial Resistance

    PubMed Central

    Cheng, Guyue; Dai, Menghong; Ahmed, Saeed; Hao, Haihong; Wang, Xu; Yuan, Zonghui

    2016-01-01

    The outbreak of antimicrobial resistance, together with the lack of newly developed antimicrobial drugs, represents an alarming signal for both human and animal healthcare worldwide. Selection of rational dosage regimens for traditional antimicrobial drugs based on pharmacokinetic/pharmacodynamic principles as well as development of novel antimicrobials targeting new bacterial targets or resistance mechanisms are key approaches in tackling AMR. In addition to the cellular level resistance (i.e., mutation and horizontal gene transfer of resistance determinants), the community level resistance (i.e., bilofilms and persisters) is also an issue causing antimicrobial therapy difficulties. Therefore, anti-resistance and antibiofilm strategies have currently become research hotspot to combat antimicrobial resistance. Although metallic nanoparticles can both kill bacteria and inhibit biofilm formation, the toxicity is still a big challenge for their clinical applications. In conclusion, rational use of the existing antimicrobials and combinational use of new strategies fighting against antimicrobial resistance are powerful warranties to preserve potent antimicrobial drugs for both humans and animals.

  9. Understanding and fighting the medicine counterfeit market.

    Dégardin, Klara; Roggo, Yves; Margot, Pierre

    2014-01-01

    Medicine counterfeiting is a serious worldwide issue, involving networks of manufacture and distribution that are an integral part of industrialized organized crime. Despite the potentially devastating health repercussions involved, legal sanctions are often inappropriate or simply not applied. The difficulty in agreeing on a definition of counterfeiting, the huge profits made by the counterfeiters and the complexity of the market are the other main reasons for the extent of the phenomenon. Above all, international cooperation is needed to thwart the spread of counterfeiting. Moreover effort is urgently required on the legal, enforcement and scientific levels. Pharmaceutical companies and agencies have developed measures to protect the medicines and allow fast and reliable analysis of the suspect products. Several means, essentially based on chromatography and spectroscopy, are now at the disposal of the analysts to enable the distinction between genuine and counterfeit products. However the determination of the components and the use of analytical data for forensic purposes still constitute a challenge. The aim of this review article is therefore to point out the intricacy of medicine counterfeiting so that a better understanding can provide solutions to fight more efficiently against it.

  10. Metabolomics in the fight against malaria

    2014-01-01

    Metabolomics uses high-resolution mass spectrometry to provide a chemical fingerprint of thousands of metabolites present in cells, tissues or body fluids. Such metabolic phenotyping has been successfully used to study various biologic processes and disease states. High-resolution metabolomics can shed new light on the intricacies of host-parasite interactions in each stage of the Plasmodium life cycle and the downstream ramifications on the host’s metabolism, pathogenesis and disease. Such data can become integrated with other large datasets generated using top-down systems biology approaches and be utilised by computational biologists to develop and enhance models of malaria pathogenesis relevant for identifying new drug targets or intervention strategies. Here, we focus on the promise of metabolomics to complement systems biology approaches in the quest for novel interventions in the fight against malaria. We introduce the Malaria Host-Pathogen Interaction Center (MaHPIC), a new systems biology research coalition. A primary goal of the MaHPIC is to generate systems biology datasets relating to human and non-human primate (NHP) malaria parasites and their hosts making these openly available from an online relational database. Metabolomic data from NHP infections and clinical malaria infections from around the world will comprise a unique global resource. PMID:25185001

  11. Fighting 'personhood' initiatives in the United States.

    PubMed

    Collins, Lee Rubin; Crockin, Susan L

    2012-06-01

    'Personhood' initiatives filed in many states within the United States threaten to impose potentially significant restrictions on infertility treatment, embryo disposition, pre-natal care, abortion, contraception, and stem-cell research, all through attempts to redefine a 'person' or 'human being' as existing from the moment of fertilization or conception, and endowed with the full legal and Constitutional rights of personhood. Virginia's recent, unsuccessful attempt to pass such legislation provides both a dramatic example of these efforts and valuable lessons in the fight against them by infertility advocates and others. Arguments over loss of infertility treatment seemed more persuasive to legislatures than did restrictions on abortion or stem cell research. Indeed, persuading legislators or voters that they could be 'pro-life' and still anti-personhood initiatives was a key strategy, and consumer efforts and media attention were instrumental. The most central lessons, however, may be the degree of intensity and coordinated strategy to shift public perception that lie behind these numerous state efforts, regardless of whether the actual initiatives are won or lost.

    Risperidone is an antipsychotic drug that is approved for use in childhood psychiatric disorders such as autism. One concern regarding the use of this drug in pediatric populations is that it may interfere with social interactions that serve to nurture brain development. This study used rats to assess the impact of risperidone administration on maternal-offspring interactions and juvenile play fighting between cage mates. Mixed-sex litters received daily subcutaneous injections of vehicle or 1.0 or 3.0mg/kg of risperidone between postnatal days (PNDs) 14-42. Rats were weaned and housed three per cage on PND 21. In observations made between PNDs 14-17, risperidone significantly suppressed several aspects of maternal-offspring interactions at 1-hour post-injection. At 23 h post-injection, pups administered risperidone had lower activity scores and made fewer non-nursing contacts with their moms. In observations of play-fighting behavior made once a week between PNDs 22-42, risperidone profoundly decreased many forms of social interaction at 1h post-injection. At 23h post-injection, rats administered risperidone made more non-social contacts with their cage mates, but engaged in less social grooming. Risperidone administration to rats at ages analogous to early childhood through adolescence in humans produces a pattern of abnormal social interactions across the day that could impact how such interactions influence brain development.

At 23 hours post-injection, rats administered risperidone made more non-social contacts with their cage mates, but engaged in less social grooming. Risperidone administration to rats at ages analogous to early childhood through adolescence in humans produces a pattern of abnormal social interactions across the day that could impact how such interactions influence brain development.

    The UAVs (Unmanned Air Vehicles) have great potentials in different civilian applications, such as oil pipeline surveillance, precision farming, forest fire fighting (yearly), search and rescue, boarder patrol, etc. The related industries of UAVs can create billions of dollars for each year. However, the road block of adopting UAVs is that it is against FAA (Federal Aviation Administration) and ATC (Air Traffic Control) regulations. In this paper, we have reviewed the latest technologies and researches on UAV navigation and obstacle avoidance. We have purposed a system design of Jittering Mosaic Image Processing (JMIP) with stereo vision and optical flow to fulfill the functionalities of autonomous UAVs.

    Military ground vehicles fires are a significant cause of system loss, equipment damage, and crew injury in both combat and non-combat situations. During combat, the ability to successfully fight an internal fire, without losing fighting and mobility capabilities, is often the key to crew survival and mission success. In addition to enemy hits in combat, vehicle fires are initiated by electrical system failures, fuel line leaks, munitions mishaps and improper personnel actions. If not controlled, such fires can spread to other areas of the vehicle, causing extensive damage and the potential for personnel injury and death. The inherent fire safety characteristics (i.e. ignitability, compartments of these vehicles play a major roll in determining rather a newly started fire becomes a fizzle or a catastrophe. This paper addresses a systems approach to assuring optimum vehicle fire safety during the design phase of complex vehicle systems utilizing extensive uses of composites, plastic and related materials. It provides practical means for defining the potential fire hazard risks during a conceptual design phase, and criteria for the selection of composite materials based on its fire safety characteristics.

    There are various kinds of autonomous vehicles (AV`s) which can operate with varying levels of autonomy. This paper is concerned with underwater, ground, and aerial vehicles operating in a fully autonomous (nonteleoperated) mode. Further, this paper deals with AV`s as a special kind of device, rather than full-scale manned vehicles operating unmanned. The distinction is one in which the AV is likely to be designed for autonomous operation rather than being adapted for it as would be the case for manned vehicles. The authors provide a survey of the technological progress that has been made in AV`s, the current research issues and approaches that are continuing that progress, and the applications which motivate this work. It should be noted that issues of control are pervasive regardless of the kind of AV being considered, but that there are special considerations in the design and operation of AV`s depending on whether the focus is on vehicles underwater, on the ground, or in the air. The authors have separated the discussion into sections treating each of these categories.

    The presence of Europe in the future developments of spatial programs, which are foreseen, for the 1990s and further, needs the availability of vehicles, modules and all related technologies adapted to operational use of low earth orbit station. The manned HERMES vehicle shall be part of the in-orbit infrastructure realized either in the European context or in cooperation between Europe and the United States. The main mission for this vehicle will be to run a shuttle with the station that means transport and change of the crews, its safe return in abort condition and cargo transport of consumable and experimental equipment. Secondary missions could be servicing on automatic platform, making autonomous scientific experiments. Lastly, the vehicle, by means of its on-board propulsion capability, could be used to accomplish in-orbit tow and assembly missions. Studies which are undertaken now about the vehicle are devoted to the aerodynamic shape (research of a compromise between aerothermic and overall fitting), the system (functional architecture, ground and flight configuration); further works dealing with technology are presently on hand in the field of thermal protection, aerodynamics, power generation with a high massic yield.

  1. Occupational exposures in California wildland fire fighting.

    1992-01-01

    Industrial hygiene measurement of exposures to wildland fire fighters was conducted in northern California during three consecutive fire seasons (1986-1989) in conjunction with three separate health effects studies. Chemicals that were monitored included carbon monoxide, total and respirable particulates, polyaromatic hydrocarbons (PAHs), crystalline silica, aldehydes, and benzene. Measurements were taken at both wildland fires and prescribed (planned) burns. A variety of collection methods were employed--colorimetric detector tubes and a CO monitor were used for direct-reading area measurements; colorimetric diffusion tubes, filter cassettes, sorbent tubes, and passive vapor monitors were used for determining personal time-weighted average exposures. A new screening method (National Institute for Occupational Safety and Health Method 2539) was used to identify the presence of specific aldehydes. Results show that wildland fire fighters may at times be exposed to concentrations of carbon monoxide, total or respirable particulates, or silica at levels near or higher than recommended occupational exposure limits, although group means were generally well below the limits. Time-weighted average formaldehyde levels, measured in a few instances above 0.37 mg/m3 (0.3 ppm), indicate a potential for formaldehyde-induced eye or respiratory irritation under these conditions. Certain characteristics of the work such as high altitude, temperature, and breathing rate; extended work shifts; and additional off-shift exposures suggest that adjustment of 8-hr exposure limits may be necessary to provide adequate protection. In part, because of the rigors of performing industrial hygiene measurements under fire fighting conditions, data are limited and could not be considered representative of the full range of exposures fire fighters may encounter.(ABSTRACT TRUNCATED AT 250 WORDS)

    The prevention of youth violence is a public health priority in many countries. We examined the prevalence of bullying victimization and physical fighting in youths in 79 high- and low-income countries and the relations between structural determinants of adolescent health (country wealth, income inequality, and government spending on education) and international differences in youth violence. Cross-sectional surveys were administered in schools between 2003 and 2011. These surveys provided national prevalence rates of bullying victimization (n = 334,736) and four or more episodes of physical fighting in the past year (n = 342,312) in eligible and consenting 11-16 year olds. Contextual measures included per capita income, income inequality, and government expenditures on education. We used meta-regression to examine relations between country characteristics and youth violence. Approximately 30% of adolescents reported bullying victimization and 10.7% of males and 2.7% of females were involved in frequent physical fighting. More youth were exposed to violence in African and Eastern Mediterranean countries than in Europe and Asia. Violence directly related to country wealth; a 1 standard deviation increase in per capita income corresponded to less bullying (-3.9% in males and -4.2% in females) and less fighting (-2.9% in males and -1.0% in females). Income inequality and education spending modified the relation between country wealth and fighting; where inequality was high, country wealth related more closely to fighting if education spending was also high. Country wealth is a robust determinant of youth violence. Fighting in affluent but economically unequal countries might be reduced through increased government spending on education.

    Physical fighting among adolescents is one manifestation of interpersonal violence that is an important issue globally, but attention to this problem in Malaysia has been limited. We analyzed data available from the Malaysia Global School-Based Health Survey conducted in 2012. Of the 25 507 respondents, 27.4% reported having been in a physical fight in the past 12 months. Being bullied (adjusted odds ratio [aOR] = 3.01; 95% confidence interval [CI] = 2.67-3.39) was significantly and highly associated with involvement in physical fighting. Smoking (aOR = 2.56; 95% CI = 2.20-2.97), males (aOR = 1.77; 95% CI = 1.62-1.93), using drugs (aOR = 1.73; 95% CI = 1.09-2.15), and drinking alcohol (aOR = 1.42; 95% CI = 1.24-1.63) were other factors associated with physical fighting. Parental supervision showed no significant association with physical fighting. These findings indicate that more attention needs to be given to bullying at school by school authorities and parents. © 2014 APJPH.

  16. A Mismatch between the Perceived Fighting Signal and Fighting Ability Reveals Survival and Physiological Costs for Bearers

    Signals of fighting indicate an animal's intention to attack and so they serve to prevent costly aggressive encounters. However, according to theory, a signal that is different in design (i.e. a novel signal) but that fails to inform fighting intentions will result in negative fitness consequences for the bearer. In the present study we used males of the territorial damselfly Hetaerina americana, which have a red wing spot during territory defense that has evolved as a signal of fighting ability. By producing a novel signal (covering the red spot with blue ink) in territory owners, we investigated: a) the behavioral responses by conspecific males; b) survival cost and c) three physiological mediators of impaired survival: muscular fat reserves, muscle mass and immune ability. We predicted that males with the novel signal would be attacked more often by conspecifics as the former would fail to convey fighting ability and intentions adequately. This will result in lower survival and physiological condition for the novel signal bearers. We found that, compared to control males (males whose red spot was not changed), experimental males had reduced survival, were less able to hold a territory, and had a reduced muscle mass. It seems that spot modified males were not able to effectively communicate their territory tenancy, which may explain why they lost their defended sites. Our results provide support for theoretical models that a novel signal that fails to informing fighting ability may lead to a fitness cost for bearers. PMID:24409304

    The Siamese fighting fish (Betta splendens) is one of the popular aquarium fish. Serious attentions have been paid to the biodiversity of the fish. The mitochondrial genome of the Siamese fighting fish is reported to be 17 099 bp and includes 37 genes. The gene organization is similar to other fish mitogenomes. The control region is AT-rich and includes three tandem repeats. Phylogenetic analysis reveals that the fish is close to fish in the Macropodus genus. This mitogenome will assist in studying the mitochondrial variations and population structure in this fish and examine the evolutionary relationship among fish in the Osphronemidae family.

    Projected mission profiles and computational models of the Hermes winged manned reentry vehicle are discussed. Launched into a low orbit with a crew of at most four by the Ariane 5 vehicle, Hermes will serve transportation, crew relief, safety, and freight carriage functions. It will have a nominal 300-500 km circular or 600-900 km heliosynchronous orbit, weigh from 13,500-16,700 kg, and return in hypersonic glide to a wheeled landing. The vehicle dimensions will be 15-18 m length, 6 m height at the tail fin, and a 10 m span. The L/D ratio will be 1.5-1.6, thereby furnishing a cross range of 2500 km. Hermes will have a Shuttle-type fuselage, carbon-carbon nose, and insulation on the extrados designed to keep the structure at 175 C or lower. The avionics will have 3-4 levels of redundance, each mission phase-dependent. Power will be supplied by three fuel cells and a bank of four Ag-Zn batteries. Hardware development is scheduled to begin in 1988.

    Understanding the determinants of fighting is important for prevention efforts. Unfortunately, there is little research on how sibling fighting is related to peer fighting. Therefore, the aim of this study was to evaluate the association between sibling fighting and peer fighting. Data are from the Boston Youth Survey 2008, a school-based sample of youth in Boston, MA. To estimate the association between sibling fighting and peer fighting, we ran four multivariate regression models and estimated adjusted prevalence ratios and 95% confidence intervals. We fit generalized estimating equation models to account for the fact that students were clustered within schools. Controlling for school clustering, race/ethnicity, sex, school failure, substance use, and caregiver aggression, youth who fought with siblings were 2.49 times more likely to have reported fighting with peers. To the extent that we can confirm that sibling violence is associated with aggressive behavior, we should incorporate it into violence prevention programming.

    Background and aims: Physical fighting and gambling are common risk behaviors among adolescents. Prior studies have found associations among these behaviors in adolescents but have not examined systematically the health and gambling correlates of problem-gambling severity amongst youth stratified by fight involvement. Methods: Survey data were used from 2,276 Connecticut high school adolescents regarding their physical fight involvement, gambling behaviors and perceptions, and health and functioning. Gambling perceptions and correlates of problem-gambling severity were examined in fighting and non-fighting adolescents. Results: Gambling perceptions were more permissive and at-risk/problem gambling was more frequent amongst adolescents reporting serious fights versus those denying serious fights. A stronger relationship between problem-gambling severity and regular smoking was observed for adolescents involved in fights. Discussion and conclusions: The more permissive gambling attitudes and heavier gambling associated with serious fights in high school students suggest that youth who engage in physical fights warrant enhanced prevention efforts related to gambling. The stronger relationship between tobacco smoking and problem-gambling severity amongst youth engaging in serious fights suggest that fighting youth who smoke might warrant particular screening for gambling problems and subsequent interventions.

  3. Biodegradability of fluorinated fire-fighting foams in water.

    Bourgeois, A; Bergendahl, J; Rangwala, A

    2015-07-01

    Fluorinated fire-fighting foams may be released into the environment during fire-fighting activities, raising concerns due to the potential environmental and health impacts for some fluorinated organics. The current study investigated (1) the biodegradability of three fluorinated fire-fighting foams, and (2) the applicability of current standard measures used to assess biodegradability of fluorinated fire-fighting foams. The biodegradability of three fluorinated fire-fighting foams was evaluated using a 28-day dissolved organic carbon (DOC) Die-Away Test. It was found that all three materials, diluted in water, achieved 77-96% biodegradability, meeting the criteria for "ready biodegradability". Defluorination of the fluorinated organics in the foam during biodegradation was measured using ion chromatography. It was found that the fluorine liberated was 1-2 orders of magnitude less than the estimated initial amount, indicating incomplete degradation of fluorinated organics, and incomplete CF bond breakage. Published biodegradability data may utilize biochemical oxygen demand (BOD), chemical oxygen demand (COD), and total organic carbon (TOC) metrics to quantify organics. COD and TOC of four fluorinated compounds were measured and compared to the calculated carbon content or theoretical oxygen demand. It was found that the standard dichromate-based COD test did not provide an accurate measure of fluorinated organic content. Thus published biodegradability data using COD for fluorinated organics quantification must be critically evaluated for validity. The TOC measurements correlated to an average of 91% of carbon content for the four fluorinated test substances, and TOC is recommended for use as an analytical parameter in fluorinated organics biodegradability tests.

    da Silva, Bruno Victor Corrêa; Ide, Bernardo Neme; de Moura Simim, Mário Antônio; Marocolo, Moacir; da Mota, Gustavo Ribeiro

    2014-12-09

    The aim of this study was to investigate the neuromuscular performance responses following successive Brazilian Jiu-Jitsu (BJJ) fights. Twenty-three BJJ athletes (age: 26.3 ± 6.3 years; body mass: 79.4 ± 9.7 kg; body height: 1.80 ± 0.1 m) undertook 3 simulated BJJ fights (10 min duration each separated by 15 min of rest). Neuromuscular performance was measured by the bench press throw (BPT) and vertical counter movement jump (VCMJ) tests, assessed before the 1st fight (Pre) and after the last one (Post). Blood lactate (LA) was measured at Pre, 1 min Post, and 15 min Post fights. Paired t-tests were employed in order to compare the BPT and VCMJ results. One-way ANOVA with Bonferroni post hoc tests were utilized to compare LA responses. The results revealed a significant (p < 0.05) increase in VCMJ performance (40.8 ± 5.5 cm Pre vs. 42.0 ± 5.8 cm Post), but no significant changes in the BPT (814 ± 167 W Pre vs. 835 ± 213 W Post) were observed. LA concentration increased significantly (p < 0.05) at Post, both in the 1st min (10.4 ± 2.7 mmol L-1) and the 15th min (6.4 ± 2.5 mmol L-1) of recovery. We concluded that successive simulated BJJ fights demanded considerable anaerobic contribution of ATP supply, reinforcing the high-intensity intermittent nature of the sport. Nevertheless, no negative impact on acute neuromuscular performance (power) was observed.

  12. Vehicle accidents related to sleep: a review

    1999-01-01

    Falling asleep while driving accounts for a considerable proportion of vehicle accidents under monotonous driving conditions. Many of these accidents are related to work--for example, drivers of lorries, goods vehicles, and company cars. Time of day (circadian) effects are profound, with sleepiness being particularly evident during night shift work, and driving home afterwards. Circadian factors are as important in determining driver sleepiness as is the duration of the drive, but only duration of the drive is built into legislation protecting professional drivers. Older drivers are also vulnerable to sleepiness in the mid-afternoon. Possible pathological causes of driver sleepiness are discussed, but there is little evidence that this factor contributes greatly to the accident statistics. Sleep does not occur spontaneously without warning. Drivers falling asleep are unlikely to recollect having done so, but will be aware of the precursory state of increasing sleepiness; probably reaching a state of fighting off sleep before an accident. Self awareness of sleepiness is a better method for alerting the driver than automatic sleepiness detectors in the vehicle. None of these have been proved to be reliable and most have shortcomings. Putative counter measures to sleepiness, adopted during continued driving (cold air, use of car radio) are only effective for a short time. The only safe counter measure to driver sleepiness, particularly when the driver reaches the stage of fighting sleep, is to stop driving, and--for example, take a 30 minute break encompassing a short (< 15 minute) nap or coffee (about 150 mg caffeine), which are very effective particularly if taken together. Exercise is of little use. CONCLUSIONS: More education of employers and employees is needed about planning journeys, the dangers of driving while sleepy, and driving at vulnerable times of the day.   PMID:10472301

    The basic principles which determine launcher design and hence constrain the spacecraft payload are determined. Some key features of the principal launcher alternatives in Europe and the U.S., namely, the unmanned, expendable Ariane and the manned, substantially reusable, Space Shuttle, are outlined. The equations of motion of the rocket are specialized to the vertical plane, parallel and normal to the flight direction, and to the motion of the center of mass and the pitch rotation. A typical Ariane 2 flight profile for transfer into GTO is illustrated. Some representative mission requirements for spacecraft launches are reviewed. Launch vehicle burnout velocities for spacecraft emplacement are given. Geostationary orbit emplacement, orbital mission performance, and configuration interactions are discussed.

    Accurate assessment of competitive ability is a critical component of contest behavior in animals, and it could be just as important in human competition, particularly in human ancestral populations. Here, we tested the role that facial perception plays in this assessment by investigating the association between both perceived aggressiveness and perceived fighting ability in fighters' faces and their actual fighting success. Perceived aggressiveness was positively associated with the proportion of fights won, after we controlled for the effect of weight, which also independently predicted perceived aggression. In contrast, perception of fighting ability was confounded by weight, and an association between perceived fighting ability and actual fighting success was restricted to heavyweight fighters. Shape regressions revealed that aggressive-looking faces are generally wider and have a broader chin, more prominent eyebrows, and a larger nose than less aggressive-looking faces. Our results indicate that perception of aggressiveness and fighting ability might cue different aspects of success in male-male physical confrontation.

  10. Onset of fights and mutual assessment in ant founding queens.

    PubMed

    Berthelot, Kévin; Portugal, Felipe Ramon; Jeanson, Raphaël

    2017-03-01

    In animals, the progress and outcome of contests can be influenced by an individual's own condition, their opponent's condition or a combination of the two. The use of chemical information to assess the quality of rivals has been underestimated despite its central role in the regulation of social interactions in many taxa. Here, we studied pairwise contests between founding queens of the ant Lasius niger to investigate whether the decision to engage in agonistic interactions relies on self-assessment or mutual assessment. Queens modulated their aggressive behaviours depending on both their own status and their opponent's status. We found no influence of lipid stores or size on the onset of fights. However, differences in cuticular chemical signatures linked to fertility status accurately predicted the probability of behaving aggressively in pairs. Our study thus suggests that ant queens could rely on mutual assessment via chemical cues to make informed decisions about fight initiation.

  11. Leveraging Primary Care in the Fight Against Lung Cancer

    2008-01-01

    In recent years, the decline in youth smoking rates has stopped as the tobacco industry strives to successfully reclaim market areas where it has lost favor. The plateau in lung cancer incidence and stagnation in progress toward smoking abstinence illustrates the necessity for renewed efforts to fight tobacco use. Barriers to fighting tobacco use exist in both the clinical arena and within the general population, but can be overcome. Primary care physicians (PCPs) are uniquely poised to successfully treat nicotine dependence with strategic targeting of these barriers, improved training in smoking cessation techniques, and focused political efforts in tobacco control. Herein, this article describes the landscape of tobacco use in America and provides background, methodology, and resources for PCPs to help achieve the goals of Healthy People 2010 in reducing the illness, disability, and death that occur as a result of tobacco use and exposure to secondhand smoke.

    VEHICLE/ENGINE Integration Issues are explored for orbit transfer vehicles (OTV's). The impact of space basing and aeroassist on VEHICLE/ENGINE integration is discussed. The AOTV structure and thermal protection subsystem weights were scaled as the vehicle length and surface was changed. It is concluded that for increased allowable payload lengths in a ground-based system, lower length-to-diameter (L/D) is as important as higher mixture ration (MR) in the range of mid L/D ATOV's. Scenario validity, geometry constraints, throttle levels, reliability, and servicing are discussed in the context of engine design and engine/vehicle integration.

    Torsion vehicle model test of Simple Structural Surfaces (SSS) model for automotive vehicle sedan is proposed in this paper to demonstrate the importance of providing continuous load path within the vehicle structures. The proposed approach is relatively easy to understand as compared to Finite Element Method (FEM). The results prove that the proposed vehicle model test is capable to show that a satisfactory load paths can five a sufficient structural stiffness within the vehicle structure. It is clearly observed that the global torsion stiffness reduces significantly when only one panel is removed from the complete SSS model. The results also five a food agreement with respect to the theoretical hypothesis as the structure is less stiff in torsion in an open section condition. The SSS model and the corresponding torsion test is obviously useful to give an overview of vehicle structural integrity. It can be potentially integrated with FEM to speed up the design process of automotive vehicle.

    Under the goals of the Vision for Space Exploration, Ares I is a chief component of the cost-effective space transportation infrastructure being developed by NASA's Constellation Program. This transportation system will safely and reliably carry human explorers back to the moon, and then onward to Mars and other destinations in the solar system. Launch Pad 39B of the Kennedy Space Flight Center (KSC), currently used for Space Shuttle launches, will be revised to host the Ares launch vehicles. The fixed and rotating service structures standing at the pad will be dismantled sometime after the Ares I-X test flight. A new launch tower for Ares I will be built onto a new mobile launch platform. The gantry for the shuttle doesn't reach much higher than the top of the four segments of the solid rocket booster. Pad access above the current shuttle launch pad structure will not be required for Ares I-X because the stages above the solid rocket booster are inert. For the test scheduled in 2012 or for the crewed flights, workers and astronauts will need access to the highest levels of the rocket and capsule. When the Ares I rocket rolls out to the launch pad on the back of the same crawler-transporters used now, its launch gantry will be with it. The mobile launchers will nestle under three lightning protection towers to be erected around the pad area. Ares time at the launch pad will be significantly less than the three weeks or more the shuttle requires. This “clean pad” approach minimizes equipment and servicing at the launch pad. It is the same plan NASA used with the Saturn V rockets and industry employs it with more modern launchers. The launch pad will also get a new emergency escape system for astronauts, one that looks very much like a roller coaster. Cars riding on a rail will replace the familiar baskets hanging from steel cables. This artist's concept illustrates the Ares I on launch pad 39B.

    To evaluate the effect of propolis against Candida species planktonic cells and its counterpart's biofilms. The MIC values, time-kill curves and filamentation form inhibition were determined in Candida planktonic cells. The effect of propolis on Candida biofilms was assessed through quantification of CFUs. MIC values, ranging from 220 to 880 µg/ml, demonstrated higher efficiency on C. albicans and C. parapsilosis than on C. tropicalis cells. In addition, propolis was able to prevent Candida species biofilm's formation and eradicate their mature biofilms, coupled with a significant reduction on C. tropicalis and C. albicans filamentation. Propolis is an inhibitor of Candida virulence factors and represents an innovative alternative to fight candidiasis.

    2016-01-01

    Status inequalities seem to play a fairly big role in creating inequalities in health. This article assumes that there can be good reasons to fight status inequalities in order to reduce inequalities in health. It examines whether the neorepublican ideal of non-dominance does a better job as a theoretical foil for this as compared to a liberal notion of non-interference. The article concludes that there is a prima facie case for incorporating non-dominance into our thinking about public health, but that it needs to go hand in hand with a more traditional liberal ideal of non-interference.

    The light-duty vehicle transportation sector in the United States depends heavily on imported petroleum as a transportation fuel. The Department of Energy’s Advanced Vehicle Testing Activity (AVTA) is testing advanced technology vehicles to help reduce this dependency, which would contribute to the economic stability and homeland security of the United States. These advanced technology test vehicles include internal combustion engine vehicles operating on 100% hydrogen (H2) and H2CNG (compressed natural gas) blended fuels, hybrid electric vehicles, neighborhood electric vehicles, urban electric vehicles, and electric ground support vehicles. The AVTA tests and evaluates these vehicles with closed track and dynamometer testing methods (baseline performance testing) and accelerated reliability testing methods (accumulating lifecycle vehicle miles and operational knowledge within 1 to 1.5 years), and in normal fleet environments. The Arizona Public Service Alternative Fuel Pilot Plant and H2-fueled vehicles are demonstrating the feasibility of using H2 as a transportation fuel. Hybrid, neighborhood, and urban electric test vehicles are demonstrating successful applications of electric drive vehicles in various fleet missions. The AVTA is also developing electric ground support equipment (GSE) test procedures, and GSE testing will start during the fall of 2003. All of these activities are intended to support U.S. energy independence. The Idaho National Engineering and Environmental Laboratory manages these activities for the AVTA.

    2015-01-01

    Adolescent fighting affects 25% of youth, with the highest rates among African-Americans and Latinos but little is known about parental views on youth fighting. The purpose of this study was to examine African-American and Latino parents’ perspectives on adolescent fighting and methods to prevent fighting. We conducted four focus groups with parents of African-American and Latino urban adolescents. Focus groups were stratified by race/ethnicity and fighting status. Groups were audiotaped, transcribed, and analyzed by three independent coders using thematic content analysis. Seventy-six percent of the 17 participants were female. Latino parents condoned fighting only as a last resort, and taught children about consequences of fighting, emotional regulation, and non-violent conflict-resolution strategies. African-American parents endorsed teaching non-violent strategies, but expressed some doubts about their effectiveness. African-American parents also suggested corporal punishment, but acknowledged that this may not be an optimal long-term strategy. Positive role modeling and involvement by teachers and other adults were cited as having important roles in fighting prevention. Suggested interventions included teaching adolescents non-violent conflict-resolution skills, anger management, and alternatives to fighting. Parents recommended that violence prevention programs incorporate the experiences of former fighters and be tailored to community needs. Study findings suggest that youth violence-prevention programs may benefit from addressing parental attitudes towards fighting and parent-child communication about fighting, teaching adolescents non-violent conflict-resolution skills, and tailoring programs by race/ethnicity. Promoting positive modeling and involvement by teachers and other adults also may be beneficial. PMID:27186064

    Burn recovery is a difficult process full of physical and psychological challenges. With increasing survival rates, there has been renewed interest in the psychological aspects of burn recovery. As men represent over 70% of all burn patients, it is particularly important to study how men experience and interpret this process. We interviewed a purposeful sample of ten adult male burn survivors from different age and cultural groups in the first 16 weeks of their recovery and asked them to discuss the problems they faced. Narrative analysis was used to interpret the interviews. In their narratives, the men tended to emphasize gains in their physical recovery; that is, they often used metaphors of "fighting" to demonstrate how committed they were to their healing. Further, they put less emphasis on the emotional aspects of their recovery. In our discussion, we compare these complex storylines to coping strategies identified in the literature and discuss why men may choose these strategies. Based on our findings we argue that it is important for health care providers to be aware of societal pressures which may influence burn survivors to minimize affective elements of burn recovery. Additionally, we encourage exploring and capitalizing on men's "fighting" stories during rehabilitation in order to foster an active role which men can take in their recovery.

    Previous studies have shown that Siamese fighting fish, Betta splendens, preferentially use right-eye during the aggressive displays. However, administration of antidepressant drugs may disrupt eye-use preference in association with a reduction in aggression; a phenomena that has not been explored in fish. The objective of the current study was to examine the effects of exposure to the antidepressant drug, fluoxetine, on lateralization in eye-use during aggressive displays in male Siamese fighting fish. Baseline aggression and lateralization in eye use of thirty fish were assessed toward live conspecifics, following which experimental subjects (n=15) were then exposed to fluoxetine (540ng/L) in a static renewal water system. Behavior was quantified again after 9 days of exposure. All of the subjects preferentially used the right-eye during aggressive responses before the exposure experiments. Fluoxetine exposed subjects showed a reduction in the time spent gill flaring as has previously been reported, indicative of a reduction in the level of aggression. Fluoxetine also had a significant effect on the lateralization in preferred eye-use while looking at their opponent. Fish exposed to fluoxetine switched from a preferential use of the right-eye during aggressive encounters prior to exposure to using their left-eye after exposure to fluoxetine. The results are discussed with regard to asymmetrical distribution of serotonin between the two brain hemispheres. Copyright © 2017 Elsevier Inc. All rights reserved.

    Infectious diseases, in which pathogens invade and colonize host cells, are responsible for one third of all mortality worldwide. Host cells use special proteins (immunoproteins) and other molecules to fight viral and bacterial invaders. The mechanisms by which immunoproteins enable cells to reduce bacterial loads and survive infections remain unclear. Moreover, during infections, some immunoproteins are known to alter the cytoskeleton, the structure that largely determines cellular mechanical properties. We therefore used an optical stretcher to measure the mechanical properties of primary immune cells (bone marrow derived macrophages) during bacterial infection. We found that macrophages become stiffer upon infection. Remarkably, macrophages lacking the immunoprotein, NLR-C4, lost the stiffening response to infection. This in vitro result correlates with our in vivo data whereby mice lacking NLR-C4 have more lesions and hence increased bacterial distribution and spread. Thus, the immune-protein-dependent increase in cell stiffness in response to bacterial infection (in vitro result) seems to have a functional role in the system level fight against pathogens (in vivo result). We will discuss how this functional link between cell mechanical properties and innate immunity, effected by actin polymerization, reduces the spread of infection.

    2008-08-01

    The fight against doping in sports commenced as a result of the death of a Danish cyclist during the Rome Olympic Games in 1960. The International Olympic Committee (IOC) established a Medical Commission (IOC-MC) which had the task of designing a strategy to combat the misuse of drugs in Olympic Sport. Some International Sport Federations (IF) and National Sports Federations followed suit, but progress was modest until the world's best male sprinter was found doped with anabolic steroids at the Olympic Games in Seoul in 1988. Further progress was made following the cessation of the cold war in 1989 and in 1999 public authorities around the world joined the Olympic Movement in a unique partnership by creating WADA--the 'World Anti-Doping Agency'. The troubled history of the anti-doping fight from the 1960s until today is reviewed. In particular, the development of detection methods for an ever increasing number of drugs that can be used to dope is described, as are the measures that have been taken to protect the health of the athletes, including those who may need banned substances for medical reasons.

  3. Philippines to seek Thai assistance in fighting AIDS.

    PubMed

    A group of Philippine officials left for Thailand to learn from the Thai government's experience in fighting AIDS. Thailand has one of the highest AIDS levels in Asia and has instituted a variety of public and private programs to deal with the disease. Health Undersecretary Carmencita Reodica, who is leading the delegation, said the Philippines does not expect as many AIDS cases as Thailand. "But if the Philippines does not improve its planning and surveillance system, we could face the same threat in the future," she said. Thailand has a good surveillance program, valuable support services such as mobile clinics, and active private groups fighting AIDS, she said. The group is to meet with Prime Minister Banharn Silpa-archa, who heads the Thai National AIDS Council, and other officials involved in Thailand's anti-AIDS campaign. Thailand has recorded 22,135 AIDS cases and 750,000 people with HIV. In comparison, the Philippine government has documented only 234 AIDS cases in the Philippines and 704 people with HIV. Health officials estimate that as many as 35,000 people in the country are infected with HIV. While Thailand monitors the number of AIDS cases in the general population, the Philippines only monitors the disease among so-called high-risk groups such as prostitutes, homosexuals, and intravenous drug users. Reodica said legislation is needed in the Philippines to support the country's AIDS program, as well as to answer ethical and legal issues concerning AIDS cases. full text

  4. [MPOWER--strategy for fighting the global tobacco epidemic].

    It is estimated that tobacco use may cause death of 5 million people in 2008, which is higher than the number of deaths attributed to tuberculosis (TB), HIV/AIDS and malaria taken together. By 2030, the number of deaths related to the tobacco epidemic could exceed annually even 8 million. Despite many difficulties, a growing number of countries undertake intensive actions aimed at tobacco control. The objective of this paper was to discuss the major objectives of the MPOWER Report issued by the World Health Organization (WHO). The MPOWER package consists a set of six key and most effective strategies for fighting the global tobacco epidemic: 1) Monitoring tobacco consumption and the effectiveness of preventive measures; 2) Protect people from tobacco smoke; 3) Offer help to quit tobacco use; 4) Warn about the dangers of tobacco; 5) Enforce bans on tobacco advertising, promotion and sponsorship; and 6) Raise taxes on tobacco. It is proven that these strategies implemented in the compatible way, effectively decreases tobacco use. In addition, MPOWER comprises epidemiological data, information on implemented tobacco control measures and their efficiency. MPOWER is the only one document of a somewhat strategic nature that is a source of information on the spread of tobacco epidemic, as well as of suggestions concerning specific actions for supporting the fight against this epidemic.

  5. Jaw morphology and fighting forces in stag beetles.

    PubMed

    The jaws of different species of stag beetles show a large variety of shapes and sizes. The male jaws are used as weapons in fights, and they may exert a very forceful bite in some species. We investigated in 16 species whether and how the forcefulness of their bite is reflected in their jaw morphology. We found a large range of maximal muscle forces (1.8-33 N; factor of 18). Species investing in large bite muscles also have disproportionately large jaw volumes. They use this additional jaw volume to elongate their jaws, increasing their chances of winning in battles. The fact that this also decreases the mechanical advantage is largely compensated for by elongated in-levers. As a result, high muscle forces are correlated with elevated bite forces (0.27-7.6 N; factor of 28). Despite the large difference in the forcefulness of their bite, all investigated species experience similar Von Mises stresses in their jaws while biting (29-114 MPa; factor of 4.0; calculated with finite element simulations). Hence, stag beetles have successfully adapted their jaw anatomy according to their bite force in fights.

    2015-01-01

    Objective. Group fighting is portrayed as a piece of Americana among delinquent youth, but the behavior produces significant multifaceted negative consequences. The current study examines the heterogeneity and correlates of group fighting using national-level data. Method. Employing data from the National Survey on Drug Use and Health between 2002 and 2013 (n = 216,852), we examine links between group fighting and temperamental, parental, and academic factors as well as other externalizing behaviors (i.e., violence, crime, substance use). Results. The prevalence of group fighting in the United States is 14.8% with 11.33% reporting 1–2 group fights and 3.46% reporting 3+ group fights. A clear severity gradient in school functioning and academic performance, sensation seeking, parental disengagement, violence and delinquency, and substance use disorders is seen in the normative, episodic, and repeat offender groups. Conclusions. Youths who participate in 3+ group fights display the exceptionality and severity of other serious/chronic/habitual antisocial youth which suggests that group fighting should be considered a significant indicator of developing criminality.

    Abstract The aim of the study was to investigate the influence of karate fights on Achilles tendon stiffness in karate competitors. Eleven male karate fighters participated in the present study. A handheld MyotonPRO device (MyotonPRO, Myoton Ltd, Estonia) was applied to measure Achilles tendon stiffness in karate fighters. The Achilles tendon was tested 5 cm above the tuber calcanei. Stiffness measurements were performed before and after eight sparring fights. Each fight lasted 2 min and was separated by a 2 min rest period. Achilles tendon stiffness for the dominant leg increased significantly from before fights (751.57 ± 123.493 N/m) to immediately after fights (809.43 ± 160.425 N/m) (p = 0.012). Presented results should be used by strength and conditioning coaches in training programs as a way to decrease the risk of injury. PMID:28469747

  15. Fighting while Parasitized: Can Nematode Infections Affect the Outcome of Staged Combat in Beetles?

    PubMed Central

    Vasquez, David; Willoughby, Anna; Davis, Andrew K.

    2015-01-01

    The effects of non-lethal parasites may be felt most strongly when hosts engage in intense, energy-demanding behaviors. One such behavior is fighting with conspecifics, which is common among territorial animals, including many beetle species. We examined the effects of parasites on the fighting ability of a saproxylic beetle, the horned passalus (Odontotaenius disjunctus, Family: Passalidae), which is host to a non-lethal nematode, Chondronema passali. We pitted pairs of randomly-chosen (but equally-weighted) beetles against each other in a small arena and determined the winner and aggression level of fights. Then we examined beetles for the presence, and severity of nematode infections. There was a non-significant tendency (p = 0.065) for the frequency of wins, losses and draws to differ between beetles with and without C. passali; non-parasitized individuals (n = 104) won 47% of their fights while those with the parasite (n = 88) won 34%, a 13% difference in wins. The number of nematodes in a beetle affected the outcome of fights between infected and uninfected individuals in an unexpected fashion: fighting ability was lowest in beetles with the lowest (p = 0.033), not highest (p = 0.266), nematode burdens. Within-fight aggression was highest when both beetles were uninfected and lowest when both were infected (p = 0.034). Collectively, these results suggest the nematode parasite, C. passali, is associated with a modest reduction in fighting ability in horned passalus beetles, consistent with the idea that parasitized beetles have lower energy available for fighting. This study adds to a small but growing body of evidence showing how parasites negatively influence fighting behavior in animals. PMID:25830367

  16. Energy efficient passenger vehicle

    SciTech Connect

    Dessert, R.

    1983-02-22

    An energy efficient passenger carrying vehicle for road use. The vehicle basically comprises a long, narrow body carrying two passengers in a back-to-back relationship. The vehicle is basically a battery powered electric vehicle that can be charged by all free energy sources; namely, the sun, the wind, human muscles and momentum. The vehicle comprises four modules, namely body, solar, and two power modules. An electric power module is located within each end of the body module. This module includes electric motors driving the vehicle supporting wheels and rechargeable batteries to power the motors. Pedals, similar to those on a bicycle, located at each power module, drive generators to help recharge the batteries during operation of the vehicle, or directly help drive the vehicle wheels. A solar module comprising a large electricity generating solar cell panel covers most of the vehicle roof to aid in charging the batteries. Means are provided to tilt the solar cell panel toward the sun about a longitudinal axis. A unique flexible duct below the solar panel serves to cool the cells and, if desired, heat the passenger compartment. Further energy savings are obtained by canting the rear wheels while steering with the front wheels, so that the vehicle moves down the road at a crab angle which provides a sail effect when wind is from the vehicle beam or aft of the beam. Regenerative braking means can be used when slowing down, on a long down grade, when sailing speed is greater than required, or any other time when vehicle momentum is greater than necessary for vehicle operation, to use the excess forward momentum to drive generators to charge the batteries. Thus, a single battery charge will be conserved and vehicle operation will be assisted in a manner giving maximum vehicle range and speed.

    1999-08-01

    As part of a project for the Defense Advanced Research Projects Agency, Sandia National Laboratories' Intelligent Systems and Robotics Center is developing and testing the feasibility of a cooperative team of robotic sentry vehicles to guard a perimeter and to perform a surround task. This paper describes on-going activities in the development of these robotic sentry vehicles. To date, we have developed a robotic perimeter detection system which consists of eight 'Roving All Terrain Lunar Explorer Rovers' (RATLER), a laptop-based base-station, and several Miniature Intrusion Detection Sensors (MIDS). A radio frequency receiver on each of the RATLER vehicles alerts the sentry vehicles of alarms from the hidden MIDS. When an alarm is received, each vehicle decides whether it should investigate the alarm based on the proximity of itself and the other vehicles to the alarm. As one vehicle attends an alarm, the other vehicles adjust their position around the perimeter to better prepare for another alarm. For the surround task, both potential field and A* search path planners have been added to the base-station and vehicles. At the base-station, the operator specifies goal and exclusion regions on a GIS map. The path planner generates vehicles paths that are previewed by the operator. Once the operator has validated the path, the appropriate information is downloaded t the vehicles. For the potential field path planner, the polygons and line segments that represent the obstacles and goals are downloaded to the vehicles, instead of the simulated paths. On board the vehicles, the same potential field path planner generates the path except that it uses the true location of itself and the nearest neighboring vehicle. For the A* path planner, the actual path is downloaded to the vehicles because of limited on-board computational power.

    VEHICLE/ENGINE Integration Issues are explored for orbit transfer vehicles (OTV's). The impact of space basing and aeroassist on VEHICLE/ENGINE integration is discussed. The AOTV structure and thermal protection subsystem weights were scaled as the vehicle length and surface was changed. It is concluded that for increased allowable payload lengths in a ground-based system, lower length-to-diameter (L/D) is as important as higher mixture ration (MR) in the range of mid L/D ATOV's. Scenario validity, geometry constraints, throttle levels, reliability, and servicing are discussed in the context of engine design and engine/vehicle integration.

    A reeling device is designed for an electrical cable supplying power to the slave slde of a remote control manipulator mounted on a movable vehicle. As the vehicle carries the slave side about in a closed room, the device reels the cable in and out to maintain a variable length of the cable between the vehicle and a cable inlet in the wall of the room. The device also handles a fixed length of cable between the slave side and the vehicle, in spite of angular movement of the slave side with respect to the vehicle. (AEC)

    A modular space vehicle chassis may facilitate convenient access to internal components of the space vehicle. Each module may be removable from the others such that each module may be worked on individually. Multiple panels of at least one of the modules may swing open or otherwise be removable, exposing large portions of the internal components of the space vehicle. Such chassis architectures may reduce the time required for and difficulty of performing maintenance or modifications, may allow multiple space vehicles to take advantage of a common chassis design, and may further allow for highly customizable space vehicles.

    Primex Aerospace Company, under contract with the U.S. Army Armament Research Development & Engineering Center (ARDEC), has developed a portable vehicle capture system for use at vehicle checkpoints. Currently when a vehicle does not stop at a checkpoint, there are three possible reactions: let the vehicle go unchallenged, pursue the vehicle or stop the vehicle with lethal force. This system provides a non-lethal alternative that will stop and contain the vehicle. The system is completely portable with the heaviest component weighing less than 120 pounds. It can be installed with no external electrical power or permanent anchors required. In its standby mode, the system does not impede normal traffic, but on command erects a barrier in less than 1.5 seconds. System tests have been conducted using 5,100 and 8.400 pound vehicles, traveling at speeds up to 45 mph. The system is designed to minimize vehicle damage and occupant injury, typically resulting in deceleration forces of less than 2.5 gs on the vehicle. According to the drivers involved in tests at 45 mph, the stopping forces feel similar to a panic stop with the vehicle brakes locked. The system is completely reusable and be rapidly reset.

    Whereas allergy to vehicle ingredients (ie, excipients and preservatives) in topical steroid vehicles is well recognized, there are no data regarding which vehicle ingredients are in common use or on which vehicles and active molecules are associated with which ingredients. To produce descriptive data on the use of allergenic vehicle ingredients in prescription topical corticosteroids. The package insert for every steroid in widespread use in the United States was obtained from the manufacturer and used to generate an ingredient list for the product. There are seven vehicle ingredients that are commonly used in topical corticosteroid vehicles that are well-known allergens: propylene glycol, sorbitan sesquioleate, formaldehyde-releasing preservatives, parabens, methylchloroisothiazolinone/methylisothiazolinone, lanolin, and fragrance. Of 166 topical corticosteroids, 128 (including all creams) had at least one of these vehicle ingredients. More generic products were free of allergens than were branded products. Solutions and ointments were the least allergenic vehicles. The most commonly present potential allergens were propylene glycol and sorbitan sesquioleate. Most prescription topical corticosteroids have the potential to cause allergic contact dermatitis owing to vehicle ingredients. Dermatologists should be aware of this possibility and should consider prescribing agents that do not contain potentially allergenic vehicle ingredients.

    The present study evaluated the temporal performance of Siamese fighting fish (Betta splendens) given short-term exposure to four fixed interval (FI) schedules of reinforcement, FI 30, 60, 120, and 240 s, during which a reinforcer (mirror image) was given for the first response (swimming through a hoop) after the interval requirement had elapsed. Response levels were generally low early in an interval and increased as the interval elapsed; wait times and break points in an interval increased with increases in the FI requirement. The results were similar to that obtained with other species and different types of responses and reinforcers, and demonstrate that the procedure is a feasible method for studying interval timing in fish.

    Heart rate increases are a fundamental adaptation to physiological stress, while inappropriate heart rate increases are resistant to current therapies. However, the metabolic mechanisms driving heart rate acceleration in cardiac pacemaker cells remain incompletely understood. The mitochondrial calcium uniporter (MCU) facilitates calcium entry into the mitochondrial matrix to stimulate metabolism. We developed mice with myocardial MCU inhibition by transgenic expression of a dominant-negative (DN) MCU. Here, we show that DN-MCU mice had normal resting heart rates but were incapable of physiological fight or flight heart rate acceleration. We found that MCU function was essential for rapidly increasing mitochondrial calcium in pacemaker cells and that MCU-enhanced oxidative phoshorylation was required to accelerate reloading of an intracellular calcium compartment before each heartbeat. Our findings show that MCU is necessary for complete physiological heart rate acceleration and suggest that MCU inhibition could reduce inappropriate heart rate increases without affecting resting heart rate.

    Firefighting foam, as a significant innovation in fire protection, greatly facilitates extinguishments for liquid pool fire. Recently, with developments in LNG industry, high-expansion firefighting foams are also used for extinguishing LNG fire or mitigating LNG leakage. Foam stabilizer, an ingredient in fire-fighting foam, stabilizes foam bubbles and maintains desired foam volume. Conventional foam stabilizers are organic molecules. In this work, we developed a inorganic based ZrP (Zr(HPO4)2 .H2O, Zirconium phosphate) plates functionalized as firefighting foam stabilizer, improving firefighting foam performance under harsh conditions. Several tests were conducted to illustrate performance. The mechanism for the foam stabilization is also proposed.

  9. Is emotional intelligence relevant to a fighting force?

    PubMed

    Daffey-Moore, Emma K

    2015-12-01

    Over the past decade, the expectations of what the fighting force are tasked to deal with has changed significantly. The high-risk, high-tempo operational environments in which personnel have deployed in recent years have been complex and diverse, creating a spectrum of conflict where having EI would be an essential attribute. EI could be beneficial for the organisation and the individuals involved, and historically, there has been a distinct lack of EI. For it to be better used within the military, the entire concept needs to be explored, accepted and integrated into training throughout the rank structure; from the recruitment process to throughout the career development with support from senior commanders. This article discusses the relevance of emotional intelligence (EI) to the British Armed Forces. Published by the BMJ Publishing Group Limited.

    "Zero incidents" is the goal every security planner should work to achieve. The tools to build a "zero incidents" environment involve: * Acknowledging that violence is preventable. * Providing optimum customer service to every visitor, patient, family member. They are all VIP'S. * A strong emphasis on documentation. * Honoring and responding to staff intuition. *A proactive threat response program-policy. * Teaching all staff the verbal/non-verbal warning signs of violence. * Proactively contacting individuals of concern, making direct contact. * Having a strong domestic violence response and support plan. Active Shooter and Code Silver planning should also involve the crucial component of violence prevention and "zero incidents" philosophy. By merging these two, security planners will achieve the best of all possible outcomes. They will teach staff how to run, hide and fight and at the same time build a culture and workforce that provides both maximum customer support and staff awareness.

    Important advances are being made in the fight against communicable diseases by using new digital tools. While they can be a challenge to deploy at-scale, GPS-enabled smartphones, electronic dashboards and computer models have multiple benefits. They can facilitate program operations, lead to new insights about the disease transmission and support strategic planning. Today, tools such as these are used to vaccinate more children against polio in Nigeria, reduce the malaria burden in Zambia and help predict the spread of the Ebola epidemic in West Africa. © The Author 2015.

  12. Combining oncolytic virotherapy and cytotoxic therapies to fight cancer.

    PubMed

    Fillat, Cristina; Maliandi, Maria Victoria; Mato-Berciano, Ana; Alemany, Ramon

    2014-01-01

    Oncolytic viruses (OV) are promising anti-cancer agents, capable of selectively replicating in tumour cells and killing them. Chemotherapy, on the other hand, remains the backbone of current cancer treatment, although it is limited by a narrow therapeutic index, significant toxicity, and frequent acquired resistance. There is an increasing body of evidence on a variety of chemotherapeutic agents that have been shown to be synergic with OV and result in increased response rates in preclinical studies. Several possible mechanisms have been proposed to mediate the enhanced anti-tumour activity of such combination treatment. Moreover, it has been shown how prodrug- activating enzymes armed oncolytic viruses promote synergy with prodrugs. In the present review we summarise the current knowledge concerning the benefits of the combination of OV and cytotoxic drug treatment and discuss the translational opportunities such therapeutic synergies have in the fight against cancer.

    2012-04-01

    Despite spectacular advances in structural biology over the past half-century, only approximately 2% of the structures in the Protein Data Bank are from eukaryotic parasites and less than 0.5% are from multicellular parasites. Even when only major human pathogens are considered, 3D structures of parasites are vastly underrepresented. Yet approximately one-third of the global burden of human disease comes from parasites. It is time to divert greater effort and resources in structural biology to benefit the fight against parasitic diseases. Using as leverage recent technological and methodological advances, a concerted effort to determine macromolecular structures from parasite pathogens would provide invaluable mechanistic insights on vital processes of the parasites and would suggest novel strategies for inhibiting infection.

  14. Energy efficient passenger vehicle

    SciTech Connect

    Dessert, R.

    1980-01-01

    An energy efficient passenger carrying vehicle for road use comprised of a long, narrow body carrying two passengers in a back-to-back relationship is described. The vehicle is basically a battery powered electric vehicle that can be charged by all free energy sources; namely, the sun, the wind, human muscles and momentum. The vehicle comprises four modules: body, solar, and two power modules. An electric power module is located within each end of the body module. This module includes electric motors driving the vehicle supporting wheels and rechargeable batteries to power the motors. Pedals, similar to those on a bicycle, located at each power module, drive generators to help recharge the batteries during operation of the vehicle, or directly help drive the vehicle wheels. A solar module comprising a large electricity generating solar cell panel covers most of the vehicle roof to aid in charging the batteries. Means are provided to tilt the solar cell panel toward the sun about a longitudinal axis. A unique flexible duct below the solar panel serves to cool the cells and, if desired, heat the passenger compartment. Further energy savings are obtained by canting the rear wheels while steering with the front wheels, so that the vehicle moves down the road at a crab angle which provides a sail effect when wind is from the vehicle beam or aft of the beam. Regenerative braking means can be used when slowing down, on a long down grade, when sailing speed is greater than required, or any other time when vehicle momentum is greater than necessary for vehicle operation, to use the excess forward momentum to drive generators to charge the batteries. Thus, a single battery charge will be conserved and vehicle operation will be assisted in a manner giving maximum vehicle range and speed.

    2013-01-01

    Background: The current study explored the relationship between fighting behavior and passage of time, across games and seasons, in an attempt to assess if violent behavior in hockey is impulsive or intentional. Hypothesis: Before engaging in fighting behavior, players assess the utility of their actions and thus will fight less when the game is on the line (third period) and when champions are crowned (postseason). Methods: An archival exploration utilizing open access databases from multiple Internet sources. Results: During the 2010-2011 National Hockey League (NHL) season, players were significantly less likely to be involved in a fight as the game was coming to a close than in its early stages. In addition, data from the past 10 NHL seasons showed that players were significantly more violent in preseason games than during the regular season. They were also least likely to be involved in a fight during the postseason. Conclusion: The converging evidence suggests that players take into account the penalties associated with fighting and are less likely to engage in violence when the stakes are high, such as at the end of a game or a season. This implies, in turn, that major acts of aggression in the league are more likely to be calculated rather than impulsive. The findings suggest that a more punitive system should diminish fighting behavior markedly. PMID:24427418

    1991-01-01

    Behavioral and biochemical effects of threat displays and fights were determined in both fed and fasted animals. A week-long fast resulted in subtle behavioral modifications and a significant reduction in muscle glycogen. Threat displays had no effect on carcass composition. In the course of fighting, fed animals degraded large amounts of lipids, glycogen and amino acids, while fasted animals degraded only glycogen. Two alternative hypotheses are proposed to explain the difference between the biochemical effects of a fight in fed and starved animals.

    1973-01-01

    An automatic vehicle detection system is disclosed, in which each vehicle whose location is to be detected carries active means which interact with passive elements at each location to be identified. The passive elements comprise a plurality of passive loops arranged in a sequence along the travel direction. Each of the loops is tuned to a chosen frequency so that the sequence of the frequencies defines the location code. As the vehicle traverses the sequence of the loops as it passes over each loop, signals only at the frequency of the loop being passed over are coupled from a vehicle transmitter to a vehicle receiver. The frequencies of the received signals in the receiver produce outputs which together represent a code of the traversed location. The code location is defined by a painted pattern which reflects light to a vehicle carried detector whose output is used to derive the code defined by the pattern.

    The goal of the U.S. Department of Energy's Advanced Vehicle Testing Activity (AVTA) is to increase the body of knowledge as well as the awareness and acceptance of electric drive and other advanced technology vehicles (ATV). The AVTA accomplishes this goal by testing ATVs on test tracks and dynamometers (Baseline Performance testing), as well as in real-world applications (Fleet and Accelerated Reliability testing and public demonstrations). This enables the AVTA to provide Federal and private fleet managers, as well as other potential ATV users, with accurate and unbiased information on vehicle performance and infrastructure needs so they can make informed decisions about acquiring and operating ATVs. The ATVs currently in testing include vehicles that burn gaseous hydrogen (H2) fuel and hydrogen/CNG (H/CNG) blended fuels in internal combustion engines (ICE), and hybrid electric (HEV), urban electric, and neighborhood electric vehicles. The AVTA is part of DOE's FreedomCAR and Vehicle Technologies Program.

    The purpose of this evaluation was to examine how increasing body armor protection with and without a fighting load impacted soldiers' performance and mobility. Thirteen male soldiers performed one performance (repeated 30-m rushing) and three mobility tasks (walk, walk over and walk under) with three different body armor configurations and an anterior fighting load. Increasing body armor protection, decreased soldier performance, as individual and total 30-m rush times were significantly longer with greater protection. While increasing body armor protection had no impact on mobility, i.e. significant effect on trunk and lower limb biomechanics, during the walk and walk over tasks, greater protection did significantly decrease maximum trunk flexion during the walk under task. Adding fighting load may negatively impact soldier mobility, as greater maximum trunk extension was evident during the walk and walk over tasks, and decreased maximum trunk flexion exhibited during the walk under task with the fighting load.

    Then aims of the current study were 1) to provide cross-national estimates of the prevalence of physical fighting and weapon carrying among adolescents aged 11-15 years; (2) To examine the possible effects of physical fighting and weapon carrying on the occurrence of physical (medically treated injuries) and emotional health outcomes (multiple health complaints) among adolescents within the theoretical framework of Problem Behaviour Theory. 20,125 adolescents aged 11-15 in five countries (Belgium, Israel, USA, Canada, FYR Macedonia) were surveyed via the 2006 Health Behaviour in School Aged Children survey. Prevalence was calculated for physical fighting and weapon carrying along with physical and emotional measures that potentially result from violence. Regression analyses were used to quantify associations between violence/weapon carrying and the potential health consequences within each country. Large variations in fighting and weapon carrying were observed across countries. Boys reported more frequent episodes of fighting/weapon carrying and medically attended injuries in every country, while girls reported more emotional symptoms. Although there were some notable variations in findings between different participating countries, increased weapon carrying and physical fighting were both independently and consistently associated with more frequent reports of the potential health outcomes. Adolescents engaging in fighting and weapon carrying are also at risk for physical and emotional health outcomes. Involvement in fighting and weapon carrying can be seen as part of a constellation of risk behaviours with obvious health implications. Our findings also highlight the importance of the cultural context when examining the nature of violent behaviour for adolescents.

    Although inducible defences have been studied extensively, only little is known about how the presence of parasites might interfere with these anti-predator adaptations. Both parasites and predators are important factors shaping community structure and species composition of ecosystems. Here, we simultaneously exposed Daphnia magna to predator cues (released by the tadpole shrimp, Triops, or by a fish) and spores of the yeast parasite Metschnikowia sp. to determine how life history and morphological inducible defences against these two contrasting types of predators are affected by infection. The parasite suppressed some Triops-induced defences: Daphnia lost the ability to produce a greater number of larger offspring, a life-history adaptation to Triops predation. In contrast, the parasite did not suppress inducible defences against fish: induction (resulting in smaller body length of the mothers as well as of their offspring) and infection acted additively on the measured traits. Thus, fish-induced defences may be less costly than inducible defences against small invertebrate predators like Triops; the latter defences could no longer be expressed when the host had already invested in fighting off the parasite. In summary, our study suggests that as specific inducible defences differ in their costs, some might be suppressed if a target prey is additionally infected. Therefore, adding parasite pressure to predator-prey systems can help to elucidate the costs of inducible defences.

    We studied prey processing in the Siamese fighting fish (Betta splendens), involving slow, easily observed head-bobbing movements, which were compared with prey processing in other aquatic feeding vertebrates. We hypothesized that head-bobbing is a unique prey-processing behaviour, which alternatively could be structurally and functionally analogous with raking in basal teleosts, or with pharyngognathy in neoteleosts. Modulation of head-bobbing was elicited by prey with different motility and toughness. Head-bobbing involved sustained mouth occlusion and pronounced cranial elevation, similar to raking. However, the hyoid and pectoral girdle were protracted, and not retracted as in both raking and pharyngognathy. High-speed videofluoroscopy of hyoid movements confirmed that head-bobbing differs from other known aquatic prey-processing behaviours. Nevertheless, head-bobbing and other prey-processing behaviours converge on a recurrent functional theme in the trophic ecology of aquatic feeding vertebrates; the use of intraoral and oropharyngeal dentition surfaces to immobilize, reduce and process relatively large, tough or motile prey. Prey processing outside the pharyngeal region has not been described for neoteleosts previously, but morphological evidence suggests that relatives of Betta might use similar processing behaviours. Thus, our results suggest that pharyngognathy did not out-compete ancestral prey-processing mechanisms completely during the evolution of neoteleosts.

    Ebolaviruses are highly infectious pathogens that cause lethal Ebola virus disease (EVD) in humans and non-human primates (NHPs). Due to their high pathogenicity and transmissibility, as well as the potential to be misused as a bioterrorism agent, ebolaviruses would threaten the health of global populations if not controlled. In this review, we describe the origin and structure of ebolaviruses and the development of vaccines from the beginning of the 1980s, including conventional ebolavirus vaccines, DNA vaccines, Ebola virus-like particles (VLPs), vaccinia virus-based vaccines, Venezuelan equine encephalitis virus (VEEV)-like replicon particles, Kunjin virus-based vaccine, recombinant Zaire Ebolavirusx2206;VP30, recombinant cytomegalovirus (CMV)-based vaccines, recombinant rabies virus (RABV)-based vaccines, recombinant paramyxovirus-based vaccines, adenovirus-based vaccines and vesicular stomatitis virus (VSV)-based vaccines. No licensed vaccine or specific treatment is currently available to counteract ebolavirus infection, although DNA plasmids and several viral vector approaches have been evaluated as promising vaccine platforms. These vaccine candidates have been confirmed to be successful in protecting NHPs against lethal infection. Moreover, these vaccine candidates were successfully advanced to clinical trials. The present review provides an update of the current research on Ebola vaccines, with the aim of providing an overview on current prospects in the fight against EVD.

    The ability of microbes to form biofilms is an important element of their pathogenicity, and biofilm formation is a serious challenge for today's medicine. Fighting the clinical complications associated with biofilm formation is very difficult and linked to a high risk of failure, especially in a time of increasing bacterial resistance to antibiotics. Bacterial species most commonly isolated from biofilms include coagulase-negative staphylococci, Staphylococcus aureus, Enterococcus faecalis, Enterococcus faecium, Escherichia coli, Proteus mirabilis, Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter spp. The frequent failure of antibiotic therapy led researchers to look for alternative methods and experiment with the use of antibacterial factors with a mechanism of action different from that of antibiotics. Experimental studies with bacteriophages and mixtures thereof, expressing lytic properties against numerous biofilm-forming bacterial species showed that bacteriophages may both prevent biofilm formation and contribute to eradication of biofilm bacteria. A specific role is played here by phage depolymerases, which facilitate the degradation of extracellular polymeric substances (EPS) and thus the permeation of bacteriophages into deeper biofilm layers and lysis of the susceptible bacterial cells. Much hope is placed in genetic modifications of bacteriophages that would allow the equipping bacteriophages with the function of depolymerase synthesis. The use of phage cocktails prevents the development of phage-resistant bacteria.

  7. Optimization of the resources management in fighting wildfires.

    Wildfires lead to important economic, social, and environmental losses, especially in areas of Mediterranean climate where they are of a high intensity and frequency. Over the past 30 years there has been a dramatic surge in the development and use of fire spread models. However, given the chaotic nature of environmental systems, it is very difficult to develop real-time fire-extinguishing models. This article proposes a method of optimizing the performance of wildfire fighting resources such that losses are kept to a minimum. The optimization procedure includes discrete simulation algorithms and Bayesian optimization methods for discrete and continuous problems (simulated annealing and Bayesian global optimization). Fast calculus algorithms are applied to provide optimization outcomes in short periods of time such that the predictions of the model and the real behavior of the fire, combat resources, and meteorological conditions are similar. In addition, adaptive algorithms take into account the chaotic behavior of wildfire so that the system can be updated with data corresponding to the real situation to obtain a new optimum solution. The application of this method to the Northwest Forest of Madrid (Spain) is also described. This application allowed us to check that it is a helpful tool in the decision-making process.

    Anxiety is a psychiatric disorder with unknown neurobiology; however, neurotransmitters like gamma-amino butyric acid, norepinephrine and serotonin (5-HT) play crucial roles in mediating anxiety. Present drug modules pose dependence risk to the patient; hence, there is a great need to develop complementary therapies to fight this disorder. Aromatherapy has also been employed in ancient times for a number of mental disorders. Mahamrituanjay Mantra, Om triambkum yajamahe, sughandhim puushtivardhanam, urvarukmev vandhanaat, mrityu mokshay mamritaat!!!!, the part of veda enlightens that aroma gives rise to good health (sughandhim puushtivardhanam). Hawan is a religious practice recommended for mental peace. Hawan is a process in which special herbs are offered in the fire of medicinal woods ignited in a specially designed fire pit. Analysis of literature demonstrates that the components of Hawan are having a number of volatile oils that are specifically useful for prevention and treatment of anxiety through some mechanism of action. Due to high temperature of fire, the vapors of these oils from herbs enter into the central nervous system through nasal route. As per modern science and ancient texts on medicine, nasal drug delivery systems are the best for the diseases related to brain and head. The routine of performing Hawan might keep the threshold value of the therapeutic components in the body and help in preventing anxiety. In the present manuscript, authors highlight and integrate the modern and ancient concepts for treatment and prevention of anxiety through scientific evidences.

    The aim of this paper was to identify basic and motor structures which determine the achievement of top results in karate among younger cadets. For this purpose, a set of 10 basic motor tests and a set of 5 situational motor karate tests were applied on a sample of 60 male and 51 female Croatian karateka aged 13 to 15. Different motor and specific motor structures according to gender were isolated by factor analysis. In male karateka, in the space of basic motor tests: Factor of explosive strength and/or force regulator, and Factor integrating muscle endurance, agility and speed of movement, and in female karateka: Factor integrating movement speed, leg explosiveness and agility and/or speed regulator, and Regulator of basic core strength and sprinting. In male karateka in the space of specific motor tests: Specific agility and Specific speed of kicks performance; and in female karateka: Factor integrating agility-mobility and speed of technique performance. Latent structure of fighting efficacy in karate differs according to gender. Thus, in male karateka, determination of efficacy is significantly contributed by two motor factors: specific speed of kicks performance as a specific factor and force regulator as a basic factor; and in female karateka: the first factor which integrates regulators of speed, force and agility, accompanied by the muscle tone regulator, as a basic factor, and the second factor which is responsible for specific agility and speed of technique performance as a specific factor.

    Women Fighting AIDS in Kenya (WOFAK) was founded in order to improve the effectiveness of existing AIDS services delivered to women in Kenya. Founded by both seropositive and seronegative women, WOFAK is unique in that it is the only AIDS support organization (ASO) in Kenya run by and for women. WOFAK contributes to the empowerment of HIV positive women and girls by assisting them in gaining control over their own health and serostatus, to live positively with the infection, and to protect their families and communities from becoming infected. WOFAK founders feel that existing ASOs address women's issues as only a small part of their programs and that most existing programs aimed at women focus on commercial sex workers. Whenever possible, WOFAK provides psychological and material support for women affected by HIV/AIDS. They conduct training in home-based care techniques and visit hospitalized members to offer counseling and support. WOFAK conducts HIV/AIDS education and outreach in schools, churches, commercial centers, and rural areas. All activities center around a network of positive women from all parts of society responding to the community and advocating for stronger responses by the government and other agencies providing HIV/AIDS prevention and care services. They stress the basic human rights of HIV positive women such as their right to marriage and reproduction, proper medical care, housing, and jobs.

Vehicles can be used to penetrate many types of perimeter barriers, transport equipment and personnel rapidly over long distances, and deliver large amounts of explosives directly to facilities in suicide missions. The function of a vehicle barrier system is to detain or disable a defined threat vehicle at a selected distance from a protected facility. Numerous facilities are installing, or planning to install, vehicle barrier systems and many of these facilities are requesting guidance to do so adequately. Therefore, vehicle barriers are being evaluated to determine their stopping capabilities so that systems can be designed that are both balanced and capable of providing a desired degree of protection. Equally important, many of the considerations that should be taken into account when establishing a vehicle barrier system have been identified. These considerations which pertain to site preparation, barrier selection, system integration and operation, and vehicle/barrier interaction, are discussed in this paper. 2 tabs.

    Fighting-related injuries are common among adolescents within the United States, but how such injuries relate to subsequent cognitive functioning remains unclear. In particular, the long-term effect of fighting-related injuries suffered during important developmental periods, such as adolescence, on subsequent cognitive functioning has been overlooked by previous studies. The purpose of this study is to examine the association between sustaining serious fighting-related injuries and changes in verbal intelligence (IQ) over a 5- to 6-year time period. Longitudinal multivariate statistical models were used to analyze data from the National Longitudinal Study of Adolescent Health collected between 1994 and 2002 and analyzed in 2013. Even a single fighting-related injury resulted in a significant reduction in IQ over time even after controlling for age, race, sex, and changes in socioeconomic status (SES) over the study period. Additionally, females experienced a significantly greater reduction in IQ from each fighting-related injury than males. Fighting-related injuries have a significant impact on subsequent cognitive functioning and intelligence. The implications for future policies and research are discussed in more detail.

    1990-04-01

    The effects of prenatal ethanol exposure on juvenile play-fighting and postpubertal aggressive behavior in rats were longitudinally assessed in the context of more conventionally applied physical and behavioral measures. Pregnant animals were treated with either 2 gm/kg/day ethanol or isocaloric sucrose over gestation Days 6-19. Reproduction and somatic variables included maternal weight over gestation, offspring weight over Days 1-90, and age at eye opening and incisor eruption. Behavioral variables consisted of negative geotaxis, olfactory discrimination, activity, juvenile play-fighting, and postpubertal aggression. Ethanol offspring had lower birth weights, but there was no significant prenatal treatment effect on subsequent offspring weights or on any other reproductive or somatic variable. Both male and female ethanol-exposed offspring exhibited more play-fighting responses when paired with same-sex controls. Postpubertal aggression levels were assessed in males only. Ethanol-exposed offspring were more aggressive than controls and there was a significant positive correlation between play-fighting and postpubertal aggression ranks. No other behavioral measures discriminated between prenatal treatment groups and none were significantly correlated with either play-fighting or postpubertal aggression rank. The results are consistent with the position that juvenile play-fighting and postpubertal aggression are subserved by common substrates. They also are consistent with predictions derived from the hypothesis concerning a response-inhibition deficit as an effect of prenatal ethanol exposure on behavior.

    The purpose of this paper is to present selected findings of a grounded theory study which aims to explore individual processes and desired outcomes of recovery from recurrent health problems in order to build up a theoretical framework of recovering in an Irish context. Volunteers include mental health service users or participants of peer support groups who have experienced recurrent mental health problems for two or more years, consider themselves in improvement, and are willing to participate in individual interviews. The current paper is based on the analysis of 15 audio recorded and transcribed interviews. We identified two open codes of ‘giving up’ and ‘fighting to get better’. Giving up was associated with accepting a passive identity of a chronic ‘mental patient’ and a lack of intrinsic motivation to get better. Fighting had both positive (fighting for) and negative (fighting against) dimensions, as well as internal and external ones. The ‘fight’ for recovery entailed substantial and sometimes risky effort. Starting such fight required strong self-sustained motivation. Service providers may need to discuss internal and external motivators of fighting for recovery with service users, with a view to including such motivators in the care plans. PMID:20074198

  6. Intelligent Vehicle Health Management

    As a part of the overall goal of developing Integrated Vehicle Health Management systems for aerospace vehicles, the NASA Faculty Fellowship Program (NFFP) at Marshall Space Flight Center has performed a pilot study on IVHM principals which integrates researched IVHM technologies in support of Integrated Intelligent Vehicle Management (IIVM). IVHM is the process of assessing, preserving, and restoring system functionality across flight and ground systems (NASA NGLT 2004). The framework presented in this paper integrates advanced computational techniques with sensor and communication technologies for spacecraft that can generate responses through detection, diagnosis, reasoning, and adapt to system faults in support of INM. These real-time responses allow the IIVM to modify the affected vehicle subsystem(s) prior to a catastrophic event. Furthermore, the objective of this pilot program is to develop and integrate technologies which can provide a continuous, intelligent, and adaptive health state of a vehicle and use this information to improve safety and reduce costs of operations. Recent investments in avionics, health management, and controls have been directed towards IIVM. As this concept has matured, it has become clear the INM requires the same sensors and processing capabilities as the real-time avionics functions to support diagnosis of subsystem problems. New sensors have been proposed, in addition, to augment the avionics sensors to support better system monitoring and diagnostics.

    As a part of the overall goal of developing Integrated Vehicle Health Management systems for aerospace vehicles, the NASA Faculty Fellowship Program (NFFP) at Marshall Space Flight Center has performed a pilot study on IVHM principals which integrates researched IVHM technologies in support of Integrated Intelligent Vehicle Management (IIVM). IVHM is the process of assessing, preserving, and restoring system functionality across flight and ground systems (NASA NGLT 2004). The framework presented in this paper integrates advanced computational techniques with sensor and communication technologies for spacecraft that can generate responses through detection, diagnosis, reasoning, and adapt to system faults in support of INM. These real-time responses allow the IIVM to modify the affected vehicle subsystem(s) prior to a catastrophic event. Furthermore, the objective of this pilot program is to develop and integrate technologies which can provide a continuous, intelligent, and adaptive health state of a vehicle and use this information to improve safety and reduce costs of operations. Recent investments in avionics, health management, and controls have been directed towards IIVM. As this concept has matured, it has become clear the INM requires the same sensors and processing capabilities as the real-time avionics functions to support diagnosis of subsystem problems. New sensors have been proposed, in addition, to augment the avionics sensors to support better system monitoring and diagnostics. As the designs have been considered, a synergy has been realized where the real-time avionics can utilize sensors proposed for diagnostics and prognostics to make better real-time decisions in response to detected failures. IIVM provides for a single system allowing modularity of functions and hardware across the vehicle. The framework that supports IIVM consists of 11 major on-board functions necessary to fully manage a space vehicle maintaining crew safety and mission

    A document describes the development and demonstration of an apparatus, called a dust mitigation vehicle, for reducing the amount of free dust on the surface of the Moon. The dust mitigation vehicle would be used to pave surfaces on the Moon to prevent the dust from levitating or adhering to surfaces. The basic principle of operation of these apparatuses is to use a lens or a dish mirror to concentrate solar thermal radiation onto a small spot to heat lunar regolith. In the case of the prototype dust mitigation vehicle, a Fresnel lens was used to heat a surface layer of regolith sufficiently to sinter or melt dust grains into a solid mass. The prototype vehicle has demonstrated paving rates up to 1.8 square meters per day. The proposed flight design of the dust mitigation vehicle is also described.

    Automatic vehicle monitoring systems are discussed. In a baseline system for highway applications, each vehicle obtains position information through a Loran-C receiver in rural areas and through a 'signpost' or 'proximity' type sensor in urban areas; the vehicle transmits this information to a central station via a communication link. In an advance system, the vehicle carries a receiver for signals emitted by satellites in the Global Positioning System and uses a satellite-aided communication link to the central station. An advanced railroad car monitoring system uses car-mounted labels and sensors for car identification and cargo status; the information is collected by electronic interrogators mounted along the track and transmitted to a central station. It is concluded that automatic vehicle monitoring systems are technically feasible but not economically feasible unless a large market develops.

    The proposed vehicle, the Lunar Material Transport Vehicle (LMTV), has a mission objective of efficient lunar soil material transport. The LMTV was designed to meet a required set of performance specifications while operating under a given set of constraints. The LMTV is essentially an articulated steering, double-ended dump truck. The vehicle moves on four wheels and has two identical chassis halves. Each half consists of a chassis frame, a material bucket, two wheels with integral curvilinear synchronous motors, a fuel cell and battery arrangement, an electromechanically actuated dumping mechanism, and a powerful microprocessor. The vehicle, as designed, is capable of transporting up to 200 cu ft of material over a one mile round trip per hour. The LMTV is capable of being operated from a variety of sources. The vehicle has been designed as simply as possible with attention also given to secondary usage of components.

  11. Hydrogen vehicle fueling station

    1995-09-01

    Hydrogen fueling stations are an essential element in the practical application of hydrogen as a vehicle fuel, and a number of issues such as safety, efficiency, design, and operating procedures can only be accurately addressed by a practical demonstration. Regardless of whether the vehicle is powered by an internal combustion engine or fuel cell, or whether the vehicle has a liquid or gaseous fuel tank, the fueling station is a critical technology which is the link between the local storage facility and the vehicle. Because most merchant hydrogen delivered in the US today (and in the near future) is in liquid form due to the overall economics of production and delivery, we believe a practical refueling station should be designed to receive liquid. Systems studies confirm this assumption for stations fueling up to about 300 vehicles. Our fueling station, aimed at refueling fleet vehicles, will receive hydrogen as a liquid and dispense it as either liquid, high pressure gas, or low pressure gas. Thus, it can refuel any of the three types of tanks proposed for hydrogen-powered vehicles -- liquid, gaseous, or hydride. The paper discusses the fueling station design. Results of a numerical model of liquid hydrogen vehicle tank filling, with emphasis on no vent filling, are presented to illustrate the usefulness of the model as a design tool. Results of our vehicle performance model illustrate our thesis that it is too early to judge what the preferred method of on-board vehicle fuel storage will be in practice -- thus our decision to accommodate all three methods.

    Launched in December 2014 atop a Delta IV Heavy from the Kennedy Space Center, the Orion vehicle's Exploration Flight Test-1 (EFT-1) successfully completed the objective to stress the system by placing the un-crewed vehicle on a high-energy parabolic trajectory replicating conditions similar to those that would be experienced when returning from an asteroid or a lunar mission. Unique challenges associated with designing the navigation system for EFT-1 are presented with an emphasis on how redundancy and robustness influenced the architecture. Two Inertial Measurement Units (IMUs), one GPS receiver and three barometric altimeters (BALTs) comprise the navigation sensor suite. The sensor data is multiplexed using conventional integration techniques and the state estimate is refined by the GPS pseudorange and deltarange measurements in an Extended Kalman Filter (EKF) that employs UDU factorization. The performance of the navigation system during flight is presented to substantiate the design.

    Fear is a psychological construct inherent in assessment of and reaction to threat. Its expression has been associated with individual differences in temperament, personality, and behavioral inhibition. Defining and subsequently assessing these individual differences in fear as a trait-like variable, however, have been largely neglected by researchers. Although there are well-established measures of fear, these primarily assess response to phobic stimuli rather than a reaction tendency to acute fear. As such, the goals of the present studies were to create, pilot, and revise a scale to assess the general construct of trait-like response to fear as it relates to underlying individual differences. Following guidelines for scale development, outlined by Haynes, Richard, and Kubany (1995 [Content validity in psychological assessment: A functional approach to concepts and methods. Psychological Assessment, 7, 238-247]) results of the current investigation provide strong, initial support for the factor structure, reliability, and construct validity of a new measure of trait-like fear: the Fight, Flight, Freeze questionnaire.

    The current study examines risk and protective factors for youth antisocial personality and behavior from a multivariate format. It is hoped that this research will elucidate those risk and protective factors most important for focus of future prevention and intervention efforts. The current study examines multiple factors associated with youth antisocial traits and behavior in a sample of 8,256 youth (mean age 14), with the goal of identifying the strongest and most consistent risk or protective factors. Data was collected from the Ohio version of the Youth Risk Behavior Surveillance System's (YRBSS) school-based Youth Risk Behavior Survey (YRBS) developed by the Centers for Disease Control (CDC). Hierarchical multiple regression analyses identified peer delinquency, drug use and negative community influences as predictive of antisocial traits. Schools and families functioned as protective factors. Youth who fought frequently tended to be male, antisocial, dug using, depressed, and associated with delinquent peers. Weapons carrying was most common among drug using, antisocial males. Television and video game use were not predictive of antisocial, fighting or weapons carrying outcomes. Developmental patterns across age ranges regarding the relative importance of specific risk factors were also examined. Strategies for intervention and prevention of youth violence that focus on peers, neighborhoods, depression, and families may be particularly likely to bear fruit.

    A viable power system technology for a surface transportation vehicle to explore the planet Mars is presented. A number of power traction systems were investigated, and it was found that a regenerative hydrogen-oxygen fuel cell appears to be attractive for a manned Mars rover application. Mission requirements were obtained from the Manned Mars Mission Working Group. Power systems weights, power, and reactants requirements were determined as a function of vehicle weights for vehicles weighing from 6,000 to 16,000 lb (2,722 to 7,257 kg), (Earth weight). The vehicle performance requirements were: velocity, 10 km/hr; range, 100 km; slope climbing capability, 30 deg uphill for 50 km; mission duration, 5 days; and crew, 5. Power requirements for the operation of scientific equipment and support system capabilities were also specified and included in this study. The concept developed here would also be applicable to a Lunar based vehicle for Lunar exploration. The reduced gravity on the Lunar surface, (over that on the Martian surface), would result in an increased range or capability over that of the Mars vehicle since many of the power and energy requirements for the vehicle are gravity dependent.

    Electric Vehicle Almanac presents an overview of the current activity in electric vehicle development. Brief highlights are given for different types of vehicles--ranging from mini town cars to high tonnage industrial trucks--produced by 48 different EV developers around the world. Most of these vehicles are concept cars, prototypes and demonstration vehicles. However, a few are cars actually in modest-volume production in Europe. Extensively covered in the almanac are research and development activities for EV batteries. As widely attested, current battery state-of-the-art is--in terms of both energy storage capacity and instant power response--at least one order of magnitude shy of putting EVs in any sort of contention with internal combustion vehicles. Two sections are worth special mention. One is excerpted from an EV thermal management study by Arthur D. Little, a renowned consulting company. This study suggests that current technology exists to make EVs practical for cold weather driving, typical of the Northeastern US. The other highlights an examination by the US Environmental Protection Agency into the energy efficiencies and costs of EVs viz-a-viz internal combustion vehicles.

    Generally, in order to improve some regional fire fighting validity, indispensable strategies are not only a reinforcement of the governmental fire fighting ability, but also a strengthening of the cooperative relationship between governmental and non-governmental fire fighting ability. However, for practical purposes, the effective strategy should be different depending on the actual situationin the subject area. So, in this study, we grasp the actual state and background of the problems that need to be solved for the improvement of the regional fire fighting validity in Bangkok as a case study, and examine the appropriate solution focusing on the relationship between official and voluntary fire fighting. Through some practicable activities such as interviews, investigati ons, and making the regional fire fighting validity map, it became clear that the problems of uncooperative relationship and the lack of trust between stakeholders should be solved first and foremost.

    The US West has more and better engineered dams, reservoirs, canals, pipelines, and water treatment plants than have ever existed in history. People in this region, however, continually worry about a water shortage, because of the West is desert. The giant public works program brings water where it is needed, resulting in the West being the fastest growing region this century. The people are overdrafting aquifers. The rivers and streams are drying up. For example, the Colorado river draining 20% of the West, but it not longer reaches the sea because its water is diverted to urban and agricultural water projects. The West is also experiencing erosion and desertification, loss of wetlands and riparian habitat and wildlife, water pollution, crop failures, and drought and water shortages. Irrigation of marginal lands brings million of tons of salt into the river systems. Bureau of Reclamation water projects are contaminating surrounding areas. Not enough water exists in the West to sustain the current pace of development. Farmers remove enough water from the Ogallala aquifer each year that its level falls 4-6 feet each year, but nature restores only a level of 0.5 inches. A 6-year drought in California has resulted in forced strict water rationing in Los Angeles and San Diego. A wave of new immigrants forces the West to learn either to use less water, to redistribute existing supplies, or to block further population growth. Denver, Colorado, has installed water meters and forces residents to install efficient toilets and shower heads, to replace lawns with artificial grass, and to implement billing systems that discourage excessive water use. Other areas are also starting conservation efforts. Cities, farmers, Indian tribes, the US Forest Service, and environmental groups are fighting over water rights, increasing the price of water. Endangered fish, loss of wetlands and riparian habitat, erosion of river banks, and water pollution are factors limiting economic growth

    2008-04-01

    Most disaster plans depend on using emergency physicians, nurses, emergency department support staff, and out-of-hospital personnel to maintain the health care system's front line during crises that involve personal risk to themselves or their families. Planners automatically assume that emergency health care workers will respond. However, we need to ask: Should they, and will they, work rather than flee? The answer involves basic moral and personal issues. This article identifies and examines the factors that influence health care workers' decisions in these situations. After reviewing physicians' response to past disasters and epidemics, we evaluate how much danger they actually faced. Next, we examine guidelines from medical professional organizations about physicians' duty to provide care despite personal risks, although we acknowledge that individuals will interpret and apply professional expectations and norms according to their own situation and values. The article goes on to articulate moral arguments for a duty to treat during disasters and social crises, as well as moral reasons that may limit or override such a duty. How fear influences behavior is examined, as are the institutional and social measures that can be taken to control fear and to encourage health professionals to provide treatment in crisis situations. Finally, the article emphasizes the importance of effective risk communication in enabling health care professionals and the public to make informed and defensible decisions during disasters. We conclude that the decision to stay or leave will ultimately depend on individuals' risk assessment and their value systems. Preparations for the next pandemic or disaster should include policies that encourage emergency physicians, who are inevitably among those at highest risk, to "stay and fight."

    Infectious diseases are known as one of the most life-threatening disabilities worldwide. Approximately 13 million deaths related to infectious diseases are reported each year. The only way to combat infectious diseases is by chemotherapy using antimicrobial agents and antibiotics. However, due to uncontrolled and unnecessary use of antibiotics in particular, surviving bacteria have evolved resistance against several antibiotics. Emergence of multidrug resistance in bacteria over the past several decades has resulted in one of the most important clinical health problems in modern medicine. For instance, approximately 440,000 new cases of multidrug-resistant tuberculosis are reported every year leading to the deaths of 150,000 people worldwide. Management of multidrug resistance requires understanding its molecular basis and the evolution and dissemination of resistance; development of new antibiotic compounds in place of traditional antibiotics; and innovative strategies for extending the life of antibiotic molecules. Researchers have begun to develop new antimicrobials for overcoming this important problem. Recently, platensimycin – isolated from extracts of Streptomyces platensis – and its analog platencin have been defined as promising agents for fighting multidrug resistance. In vitro and in vivo studies have shown that these new antimicrobials have great potential to inhibit methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, and penicillin-resistant Streptococcus pneumoniae by targeting type II fatty acid synthesis in bacteria. Showing strong efficacy without any observed in vivo toxicity increases the significance of these antimicrobial agents for their use in humans. However, at the present time, clinical trials are insufficient and require more research. The strong antibacterial efficacies of platensimycin and platencin may be established in clinical trials and their use in humans for coping with multidrug resistance may be

    Blast fishing (using explosives to catch fish) causes extensive damage to coral reefs, especially in the Coral Triangle in Southeast Asia. Subsistence fishermen and larger consortiums, often with criminal links, throw an explosive into a school of fish, killing all sea life within range. This unsustainable practice is becoming more prevalent, and threatens the protein supply of as many as a billion people. Ending blast fishing will require combined technical and societal methods aimed at both deterring the practice, and catching those responsible. Our work aims to significantly improve enforcement. We are re-purposing SST's ShotSpotter gunshot detection system, (trusted and valued by police around the world), substituting hydrophones for the present microphones. Using multilateration and trained human reviewers, the system can give prompt blast alerts, location data, and acoustic waveforms to law enforcement officials. We hope to establish a prototype system in Malaysia in 2015, and have already secured governmental approvals for installation and tests with local law enforcement. The Scubazoo media firm in Malaysia is working with resorts, dive operations, and celebrity sponsors, and is planning to produce videos to illustrate the severity of the problem to both governments and the public. Because there is little hard data concerning the prevalence of blast fishing in either marine protected areas or open waters, the system can also indicate to the world the actual blast rates and patterns of use. The Teng Hoi environmental NGO in Hong Kong showed in 2004 that acoustic waves from typical bombs propagate on the order of 20 km, so an underwater locator system with a small number of sensors can feasibly cover a sizable coral region. Our present plans are to mount sensors on piers, buoys, and boats, but if possible we would also like to integrate with other existing acoustic arrays to strengthen the fight against blast fishing.

    Automatic face recognition (AFR) is a challenging task that is increasingly becoming the preferred biometric trait for identification and has the potential of becoming an essential tool in the fight against crime and terrorism. Closed-circuit television (CCTV) cameras have increasingly been used over the last few years for surveillance in public places such as airports, train stations and shopping centers. They are used to detect and prevent crime, shoplifting, public disorder and terrorism. The work of law-enforcing and intelligence agencies is becoming more reliant on the use of databases of biometric data for large section of the population. Face is one of the most natural biometric traits that can be used for identification and surveillance. However, variations in lighting conditions, facial expressions, face size and pose are a great obstacle to AFR. This paper is concerned with using waveletbased face recognition schemes in the presence of variations of expressions and illumination. In particular, we will investigate the use of a combination of wavelet frequency channels for a multi-stream face recognition using various wavelet subbands as different face signal streams. The proposed schemes extend our recently developed face veri.cation scheme for implementation on mobile devices. We shall present experimental results on the performance of our proposed schemes for a number of face databases including a new AV database recorded on a PDA. By analyzing the various experimental data, we shall demonstrate that the multi-stream approach is robust against variations in illumination and facial expressions than the previous single-stream approach.

    Solid organs have been transplanted for decades. Since the improvement in graft selection and in medical and surgical procedures, the likelihood of graft function after 1 year is now close to 90%. Nonetheless even well-matched recipients continue to need medications for the rest of their lives hence adverse side effects and enhanced morbidity. Understanding Immune rejection mechanisms, is of increasing importance since the greater use of living-unrelated donors and genetically unmatched individuals. Chronic rejection is devoted to T-cells, however the role of B-cells in rejection has been appreciated recently by the observation that B-cell depletion improve graft survival. By contrast however, B-cells can be beneficial to the grafted tissue. This protective effect is secondary to either the secretion of protective antibodies or the induction of B-cells that restrain excessive inflammatory responses, chiefly by local provision of IL-10, or inhibit effector T-cells by direct cellular interactions. As a proof of concept B-cell-mediated infectious transplantation tolerance could be achieved in animal models, and evidence emerged that the presence of such B-cells in transplanted patients correlate with a favorable outcome. Among these populations, regulatory B-cells constitute a recently described population. These cells may develop as a feedback mechanism to prevent uncontrolled reactivity to antigens and inflammatory stimuli. The difficult task for the clinician, is to quantify the respective ratios and functions of “tolerant” vs. effector B-cells within a transplanted organ, at a given time point in order to modulate B-cell-directed therapy. Several receptors at the B-cell membrane as well as signaling molecules, can now be targeted for this purpose. Understanding the temporal expansion of regulatory B-cells in grafted patients and the stimuli that activate them will help in the future to implement specific strategies aimed at fighting chronic allograft

    Background A significant body of research has demonstrated an association between adolescent alcohol consumption and subsequent fights and injuries. To date, however, no research has identified which brands are associated with alcohol-related fights and injuries among underage drinkers. Objectives We aimed to: 1) report the prevalence of alcohol-related fights and injuries among a national sample of underage drinkers in the U.S. and 2) describe the relationship between specific alcohol brand consumption and these alcohol-related negative consequences. Methods We recruited 1,031 self-reported drinkers (ages 13–20 years) via an internet panel maintained by Knowledge Networks to complete an online survey. Respondents reported their past-month overall and brand-specific alcohol consumption, risky drinking behavior, and past-year alcohol-related fights and injuries. Results Over one-quarter of the respondents (26.7%, N=232) reported at least one alcohol-related fight or injury in the past year. Heavy episodic drinkers were over six times more likely to report one of these negative alcohol-related consequences (AOR: 6.4, 95% CI: 4.1–9.9). Respondents of black race and those from higher-income households were also significantly more likely to report that experience (AOR: 2.2, 95% CI: 1.3–3.7; AOR: 1.8, 95% CI: 1.1–3.0 and 1.1–3.2, respectively). We identified eight alcohol brands that were significantly associated with alcohol-related fights and injuries. Conclusions/Importance Alcohol-related fights and injuries were frequently reported by adolescent respondents. Eight alcohol brands were significantly more popular among drinkers who experienced these adverse consequences. These results point to the need for further research on brand-specific correlates of underage drinking and negative health outcomes. PMID:25612075

    In a previous work we found that size-matched Chasmagnathus crabs establish winner-loser relationships that were stable over successive encounters but no evidence of escalation was revealed through fights. Here, we evaluated the hypothesis that size-matched fights between these crabs would be resolved according to the contestants' level of aggressiveness. Moreover, we aim at analysing the proximate roots of aggression, addressing the influence of the biogenic amines serotonin (5HT) and octopamine (OA) in crab's agonistic behaviour. To achieve these purposes, the following experiments were carried out. First, we performed successive fight encounters between the same opponents, varying the number of encounters and the interval between them, to assess the stability and progression of the winner-loser relationship. Then, we analysed dominance relationships in groups of three crabs, evaluating the emergence of linearity. Thirdly, we examined the effects of 5HT and OA injections over the fight dynamics and its result. Our findings show that contest outcome is persistent even through four encounters separated by 24h, but a comparison between encounters does not reveal any saving in fight time or increase in the opponent disparity. Within a group of crabs, a rank-order of dominance is revealed which is reflected in their fight dynamics. Interestingly, these results would not be due to winner or loser effects, suggesting that fight outcome could be mainly explained as resulting from differences in the level of aggressiveness of each opponent. Moreover, this individual aggressiveness can be modulated in opposite directions by the biogenic amines 5HT and OA, being increased by 5HT and decreased by OA.
