    Tie recent war, to be sure, Pas lad a potent part in causing stress and strain to young and old of this generation from anxiety, fear, grief, and bereavement to the uprooting of thousands of youth for the nation1s service then trying to relocate them and their families in the post war days. Adjustments from surface to air travel, with possible weekends in Europe, tell how man has mastered time and space in this world of ours. Now the great unsolved problem before him is mastering himself. His physical prowess, greatly magnified through machines which his own brain has invented, has far exceeded his spiritual strength, also far exceeded his knowledge of his own health and welfare. So those of us who wish to keep pace and contribute to the world\u27s work must of necessity be strong enough in mind and body to be able to equate ourselves in balanced living in this magic modern world. Etheridge says, balance living gives health to body, mind, and heart. This involves more than just wishful thinking on our part. It calls for sober planning of our lives with definite health goals, not only in our minds but in our daily practices. We must seek to live larger lives than just routine. Abundant living with work bring? radiance and service into life. Thus it is found that health is the best working tool for operation on the highest level of which we are capable, the is, being useful contributing members of a society which demands service to our 2 community and to our nation and to the world

    Insights on magmatic addition beneath the mid-Atlantic Coastal Plain from crustal seismic refraction data

    Magmatic addition can lead to intraplate crustal growth through plume-generated voluminous underplating of mafic material, particularly during early syn-rift processes. In addition, magmatism facilitates crustal growth and rift development by assisting extensional tectonic forces. Therefore, understanding the relationship between magmatism and rifting may help explain both these processes. In the summer of 2015 the GeoPRISMS Eastern North American Margin (ENAM) Community Seismic Experiment collected two margin-dip active source seismic refraction profiles in eastern North Carolina and southeastern Virginia using five onshore explosive shots on a northern profile and six on a southern profile (see figure). Analysis of these data resulted in 2-D P-wave velocity models of each onshore profile that reveal a crustal thickness between 36-43 km and a high velocity (7.0-7.3 km/s) layer between 5-11 km thick at the base of the crust. We interpret this feature as representing mafic magmatic addition, likely equivalent to the high velocity lower crust layer previously observed offshore at the transition between rifted continental crust and oceanic crust. Additionally, we observe slightly elevated velocities throughout the crust, which we interpret as metamorphic alteration in the mid- and upper-crust in response to magmatic addition from below. This magmatic addition could be related to Jurassic-aged syn-rift magmatism along the ENAM and/or to the voluminous Central Atlantic Magmatic Province (CAMP), and suggests that rift-related ENAM magmatism may be more voluminous than previously thought

    Measured impact of crooked traceroute

    Data collected using traceroute-based algorithms underpins research into the Internet’s router-level topology, though it is possible to infer false links from this data. One source of false inference is the combination of per-flow load-balancing, in which more than one path is active from a given source to destination, and classic traceroute, which varies the UDP destination port number or ICMP checksum of successive probe packets, which can cause per-flow load-balancers to treat successive packets as distinct flows and forward them along different paths. Consequently, successive probe packets can solicit responses from unconnected routers, leading to the inference of false links. This paper examines the inaccuracies induced from such false inferences, both on macroscopic and ISP topology mapping. We collected macroscopic topology data to 365k destinations, with techniques that both do and do not try to capture load balancing phenomena.We then use alias resolution techniques to infer if a measurement artifact of classic traceroute induces a false router-level link. This technique detected that 2.71% and 0.76% of the links in our UDP and ICMP graphs were falsely inferred due to the presence of load-balancing. We conclude that most per-flow load-balancing does not induce false links when macroscopic topology is inferred using classic traceroute. The effect of false links on ISP topology mapping is possibly much worse, because the degrees of a tier-1 ISP’s routers derived from classic traceroute were inflated by a median factor of 2.9 as compared to those inferred with Paris traceroute

    Paradoxical systolic and diastolic flow abnormalities in hypertrophic cardiomyopathy with mid-cavity systolic obstruction

    Get PDF
    Systolic obstruction of the left ventricular outflow tract, either at rest or during provocation, is a frequent finding in patients with hypertrophic cardiomyopathy. Mid-cavity obstruction is uncommon, and intraventricular diastolic pressure gradients in association with either mid-cavity of apical hypertrophy are reported only rarely. We describe a patient with hypertrophic cardiomyopathy with evidence of systolic mid-cavity obstruction, and with complex diastolic paradoxical flow abnormalities within the left ventricular cavity detected by colour and pulsed-wave Doppler. Contrast echocardiography confirmed the presence of diastolic and systolic obstruction at the mid-ventricular level, with evidence of an apical cavity sequestered from the main body of the left ventricle during systolic mid-cavity obliteration.

    Per-hop Internet Measurement Protocols

    Accurately measuring per-hop packet dynamics on an Internet path is difficult. Currently available techniques have many well-known limitations that can make it difficult to accurately measure per-hop packet dynamics. Much of the difficulty of per-hop measurement is due to the lack of protocol support available to measure an Internet path on a per-hop basis. This thesis classifies common weaknesses and describes a protocol for per-hop measurement of Internet packet dynamics, known as the IP Measurement Protocol, or IPMP. With IPMP, a specially formed probe packet collects information from intermediate routers on the packet's dynamics as the packet is forwarded. This information includes an IP address from the interface that received the packet, a timestamp that records when the packet was received, and a counter that records the arrival order of echo packets belonging to the same flow. Probing a path with IPMP allows the topology of the path to be directly determined, and for direct measurement of per-hop behaviours such as queueing delay, jitter, reordering, and loss. This is useful in many operational situations, as well as for researchers in characterising Internet behaviour. IPMP's design goals of being tightly constrained and easy to implement are tested by building implementations in hardware and software. Implementations of IPMP presented in this thesis show that an IPMP measurement probe can be processed in hardware without delaying the packet, and processed in software with little overhead. This thesis presents IPMP-based measurement techniques for measuring per-hop packet delay, jitter, loss, reordering, and capacity that are more robust, require less probes to be sent, and are potentially more accurate and convenient than corresponding measurement techniques that do not use IPMP

    British Prime Minister Tony Blair’s Irish Potato Famine Apology

    Get PDF
    In June 1997, Prime Minister Tony Blair issued a statement expressing remorse for the British government’s inaction to assist the Irish during the potato famine of the late 1840s. Blair’s contrition was met with praise and criticism, but it proved to be part of the larger narrative in the peace negotiations within Northern Ireland. Although Blair’s apology is often cited as an exemplar of political leaders apologizing for historical injustices, little actual scholarly work on this subject has been conducted. To that end, this paper examines Blair’s potato famine apology through the theory of collective apology. We argue that collective apologies serve to build, repair, renew, and strengthen bonds between communities harmed by historical wrongdoing. Moreover, collective apologies are meditations in collective memory about the past, present, and future relationship between communities. We assess Blair’s apology through this theoretical lens, discussing the potential impact that it had on the Northern Ireland peace process

    “Nanopartículas de Hierro con Tamaño Controlado Depositadas sobre Clinoptilolita por la Técnica de Electroless Plating Method- Coprecipitación: Síntesis y Caracterización”

    En el presente trabajo se ha abordado el estudio de la concentración de HCl sobre la activación con SnCl2 de una Zeolita sintetica tipo A de Sodio, que denominaremos Clinoptilolita (CLT), para la depositación en su superficie de óxidos de hierro de tamaño nanomaetrico mediante una técnica conjunta de Electroless Plating Method-Coprecipitación. La razón de utilizar una zeolita como sustrato surge de querer aprovechar sus dimensiones para obtener depósitos de tamaño nanométrico, esto con el fin de que el sustrato sea evaluado a futuro como un material compuesto que presente propiedades magnéticas, de catálisis heterogénea, conducción térmica o de reforzamiento mecánico, esta ultima si se le llegase a utilizar como carga en polímeros

    Speedtrap: Internet-Scale IPv6 Alias Resolution

    Proceedings of the Thirteenth ACM SIGCOMM Internet Measurement (IMC 2013) Conference, Barcelona, ES, October 2013.The article of record as published may be located at http://dx.doi.org/10.1145/2504730.2504759.Impediments to resolving IPv6 router aliases have precluded understanding the emerging router-level IPv6 Internet topology. In this work, we design, implement, and validate the first {\em Internet-scale alias resolution technique} for IPv6. Our technique, \st, leverages the ability to induce fragmented IPv6 responses from router interfaces in a particular temporal pattern that produces distinguishing per-router fingerprints. Our algorithm surmounts three fundamental challenges to Internet-scale IPv6 alias resolution using fragment identifier values: (1) unlike for IPv4, the identifier counters on IPv6 routers have no natural velocity, (2) the values of these counters are similar across routers, and (3) the packet size required to collect inferences is 46 times larger than required in IPv4. We demonstrate the efficacy of the technique by producing router-level Internet IPv6 topologies using measurements from CAIDA's distributed infrastructure. Our preliminary work represents a step toward understanding the Internet's IPv6 router-level topology, an important objective with respect to IPv6 network resilience, security, policy, and longitudinal evolution
