    Silicon microstructure arrays for DNA extraction by solid phase sample contacting at high flow rates

    Rapid and large sample volume processing capabilities are required for many clinical and environmental point of care genetic diagnostics scenarios. In this paper we describe the development of a silicon monolithic device for high flow rate DNA extraction. The silicon presents silica surfaces and with chaotropic salt solutions can be used for solid phase extraction. The microfluidic device was designed with the aid of simulation methods and consists of a chamber containing a densely packed alternating array of teardrop-shaped microstructures. The microstructures repeatedly separate and recombine flows, and produce a near homogeneous flow distribution to favour DNA contact with the large silica surface areas. Extremely high flow rate operation (e.g. 10 mL min-1 can be achieved without device failure. Low DNA loading and elution flow rates C At high flow rates the DNA extraction capability is retained and is independent of were used to determine a binding capacity of 57 ± 15 ng cm-2 the sample DNA concentration. High flow rate operation is preferred for the rapid extraction of rare DNA species from large sample volumes, and makes the device ideal for inclusion within a fully integrated genetic diagnostics system

    Jack Alive / Martin Dead : The Location of the "Author" in Jack London\u27s Martin Eden

    No full text
    This essay is an attempt to read Martin Eden, Jack Londonʼs autobiographical novel, in terms of the inextricable relationship between the author and the protagonist. Critics have often taken the unbalanced plot and the lack of ironic distance between narrator and character in Martin Eden as the technical weakness of London, but this paper argues that the achievement of this novel owes a great deal to the attachment of London to Martin. The unbalanced structure is a necessary product of the severe struggle of the author to kill his romantic alter ego. // Martin, who aspires to win Ruth Morse, tries to cross class boundaries by making a career of a writer. Even after realizing the emptiness of Ruth, who turns out to be nothing but a typical figure of the bourgeoisie, he somehow persists in loving her. The notion underlying here is that, for Martin, love, career and art are fundamentally inseparable. He objects to the aestheteʼs view of Brissenden on account of his separation of art from career. Martinʼs identity and life consist only in the triunity of love/career/art; the alternative is the repudiation of life. Thus, the unnatural delay of his disappointment in love can be regarded as Londonʼs strategy to set the suicide of Martin as the necessary consequence of the story. // By finishing the story and killing Martin, London finally detaches himself from Martin, reconstructs his self, and, unlike Martin, survives as a professional writer. In this sense, Martin Eden is a story about “writerʼs self-reconstruction.

    The Portrayal Of Hedonism In How To Sell by Clancy Martin

    This study aims to understand the depiction of hedonism in the novel How to Sell by Clancy Martin. This novel tells about the life journey of Bobby Clark, who followed his brother to sell jewelry. This research focuses on two problem formulations, namely; (1) what type of hedonism appears in the novel, and (2) the impact of hedonism on the main character in How to Sell.In this study, four types of hedonism emerged: Folk Hedonism, Hedonistic Egoism, Motivational Hedonism, and Value Hedonism. A reader response theory is employed to describe the point of view of the researcher seen the Novel.This study found four forms of hedonism in Bobby. The first is folk hedonism related to his bad habit of consuming drugs; the second is hedonistic egoism associated with Bobby’s habit of stealing from childhood. The third finding is that motivational hedonism is related to the reason Bobby shows off his wealth to his girlfriend and family by buying many luxury items. Value hedonism is associated with Bobby’s money in the jewelry business, which gives him happiness.This study shows that an individual’s bad habits have a detrimental impact on himself and others. Bad habits can also be transmitted to the people around us and bring harmful effects into their lives. Bad habits in stealing and abusing drugs can create a series of events that have fatal consequences in our lives and those around us. In addition, seeking recognition from others for their efforts and sacrifices is futile

    Experiences Using Large Scale Video Walls for Distance Education

    We describe our experiences building and using the Rutgers Videowall, a low-cost telepresence system that has been used teaching 15 courses and colloquia. By relaxing typical spatial telepresence features, such as background continuity, we greatly reduced costs and gained flexibility in the rooms it could be deployed in. The lower costs and room flexibility enabled academic departments to use the wall, in contrast to traditional telepresence systems which remained inaccessible. We found that the Videowall’s spatial distortions did not have a significant impact on useability, as our initial survey results show that students had an overall positive experience.Technical report DCS-tr-72

    In May 2011, the Ignatian Faculty Scholars at Regis University conducted a Skype interview with Father James Martin, S. J., author of The Jesuit Guide to Almost Everything. The Scholars had used Father Martin’s book as a text for their year of study, which focused on Ignatian Spirituality, the Ignatian Pedagogical Paradigm, and teaching and learning at a Jesuit university. The interview was transcribed and is printed below. Father Martin reflects on the book, and responds to questions about the book itself, about finding God in all learners, and about the Church
