Viscosity of non-Newtonian suspensions

The object of this project ras to obtain a reasonable correlation of the effect of velocity, concentration and particle size on apparent viscosity of non-Newtonian slurries. Through the use of dimensional and graphical analysis an equation, μ/μw=1.02(Ak/GC).105, was developed which filled these conditions. The average deviation of the apparent viscosity calculated from this equation compared to the experimental value was 14.4%. The authors believe that this correlation should be tested under a greater variety of conditions of particle size and particle thermal conductivity and for suspending mediums other than water

Of Arms and the Militia: Gun Regulation by Defining “Ordinary Military Equipment”

Recent mass shootings have placed pressure on Congress and state legislatures to regulate semi-automatic rifles and handguns in the interest of public safety. However, the Second Amendment provides that, “[a] well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed. There is no obvious public safety exception. Semi-automatic rifles, handguns, and other kinds of arms can be regulated more effectively by defining the “ordinary military equipment” militia members are expected to provide. This may be accomplished using the rationale employed by the United States Supreme Court in its 1939 decision of United States v. Miller, which upheld the National Firearms Act of 1934. The Firearms Act regulated automatic weapons, including machine guns, short-barreled shotguns, and short-barreled rifles, by requiring possessors to register them and pay a substantial tax. In its 2008 decision of the District of Columbia v. Heller, the Supreme Court reaffirmed the holding in Miller. In Heller, the Supreme Court found that the Second Amendment protected an individual’s right to keep and bear arms. The Court in Heller stated that Miller “stands only for the proposition that the Second Amendment right, whatever its nature, extends only to certain types of weapons” and that it “does not protect those weapons not typically possessed by law-abiding citizens for lawful purposes, such as short-barreled shotguns. Thus, the rationale employed in Miller is still effective and shows how certain types of weapons may be regulated

Science and Technology in Elijah Muhammad’s Nation of Islam

This article explores the centrality of science and technology to religious thought and practice in Elijah Muhammad’s Nation of Islam from the 1950s through the 1970s. Tracing the dynamic meanings of scientific knowledge in the context of the postwar United States, the article’s central argument is that like other UFO and extraterrestrial religions, the Nation of Islam emphasized scientific, material, and empirical over spiritual and supernatural understandings of religion. It also suggests how members of this new religious movement studied and attempted to live according to the scientific and mathematical principles derived from their prophet’s cosmological, ontological, and eschatological teachings on the nature of God, the origins and destiny of the black race, and the beginning and end of white supremacy

Transnational Muslim Americans: Four Women in Jordan

This article examines the biographies of four Muslim American women who have lived in Amman, Jordan. It seeks to understand how residency in this Muslim-majority country in the Middle East has affected their religious attitudes and practices as well as their gender, ethnic, and national identities. In offering analysis of these women’s own thinking about how their time in Jordan hador had not altered their Muslim and American identities and practices, this article contributes to larger scholarly conversations about religion and politics in transnational perspective. The travel and observations of these four women in Amman evidenced the often unpredictable nature of personal change when a human being moves, both physically and spiritually, from one place to another. Their stories confirm that the focus of much social scientific literature on transnationalism on how institutions—both formal and informal, state and non-state--delimit, constrain, and shape political identity is useful and necessary in understanding transnational ventures. But it also shows that such literature does not always account for the possible religious meanings of human movement. The transnational Muslim Americans in this study engage in ethical and cosmic, national and transnational practices all at once. Their stories show how an account sensitive to religious activity can helpfully account for the multiple meanings of transnational practice among Muslim Americans

Synthetic shuffling and in vitro selection reveal the rugged adaptive fitness landscape of a kinase ribozyme

The relationship between genotype and phenotype is often described as an adaptive fitness landscape. In this study, we used a combination of recombination, in vitro selection, and comparative sequence analysis to characterize the fitness landscape of a previously isolated kinase ribozyme. Point mutations present in improved variants of this ribozyme were recombined in vitro in more than 10[superscript 14] different arrangements using synthetic shuffling, and active variants were isolated by in vitro selection. Mutual information analysis of 65 recombinant ribozymes isolated in the selection revealed a rugged fitness landscape in which approximately one-third of the 91 pairs of positions analyzed showed evidence of correlation. Pairs of correlated positions overlapped to form densely connected networks, and groups of maximally connected nucleotides occurred significantly more often in these networks than they did in randomized control networks with the same number of links. The activity of the most efficient recombinant ribozyme isolated from the synthetically shuffled pool was 30-fold greater than that of any of the ribozymes used to build it, which indicates that synthetic shuffling can be a rich source of ribozyme variants with improved properties.National Institutes of Health (U.S.) (Grant GM061835
