Method of fluxless brazing and diffusion bonding of aluminum containing components

A method of diffusion bonding and fluxless brazing of aluminum containing components is reported. The aluminum surfaces are freed of any aluminum oxide coating and are coated with a polymeric sealer which can be thermally removed leaving essentially no residue. The polymeric sealer is being removed in a substantially oxygen free environment, and the aluminum components are then being brazed or diffusion bonded without the use of a flux to remove oxide coating

Suppression of Argonaute 2 Transcript Levels in Du182A Cells

RNA interference (RNAi) uses double-stranded RNA (dsRNA) molecules to degrade and suppress the transcript level of a complementary mRNA target1. The RNAi pathway is complex and includes many different proteins, like argonautes, in the core machinery. Argonautes are dsRNA binding proteins which help recognize and cleave target mRNA molecules. In our experiments, we attempted to suppress the transcript level of argonaute 2 (Ago2) in a Diabrotica undecimpunctata cell line (Du182A) using dsRNA, with the idea of disrupting the RNAi pathway using an RNAi of RNAi technique. Ago2 transcript levels were suppressed following treatment with dsRNA. Future experiments can now use this technique, with some modification to better understand the RNAi pathway

Evaluating the Latent Variable Structure of Episodic Long-Term Memory Abilities

I investigated how recall and recognition differ depending on the nature of the memory items and what one is asked to remember about them. Participants were asked to remember lists of various types of verbal items, including words, nonwords, common first names, and the names of common objects in pictures that they viewed, or to remember the contextual information that accompanied those items, including their size, location, color, or font. Immediately following presentation of each list, free recall or recognition tests for items or context were administered. It has been proposed that memory for context, or source memory, differs from episodic memory for items themselves. Exploratory factor analysis suggested that the tasks studied consisted ofthat item recognition and item recall are separate abilities, but did not provide evidence for a separate memory for context

Living Through Terror and Terror Through Living: The Biopolitical Dimensions of Religion, Security, and Terrorism

Recent emphasis and attention by thinkers, media pundits, and politicians on terrorism requires new, critical evaluation of the processes by which terrorism is understood. By investigating the concept of biopolitics, as developed specifically through Michel Foucault and Giorgio Agamben, new insights into the interactions between terrorism, politics, and religion can emerge. Most notably, the attempts to explain terror as simply an economic problem, an excessive form of violence, and/or as religious fervency gone awry rely on embedded biopolitical concepts. The continual attempts to solve terrorism through increased biopolitical strategies, thereby making terrorism a problem for biopolitics, only further substantiate the crisis that biopolitics brings about in the first place. Carefully investigating the relationship between biopolitical theory and religious concepts uncovers those very motivations of defining terrorism in certain forms (economically problematic, excessively violent, religiously passionate), and the continued insistence that terrorism is another problem to be solved, like any other political issue. Instead, I propose that by taking the religious concepts of biopolitics seriously, we can reimagine terror as heresy, requiring a different political calculus articulating terrorism not as a problem for biopolitics to fix but instead as a problem of biopolitics

Effective Processes for Dealing With Destructive Managers

Companies and organizations often struggle with employees who are hired for management positions but lack interpersonal skills and whose behavior is volatile, belittling, and destructive toward their subordinates, peers, and sometimes the organization itself. The outcomes of such behavior are damaged corporate cultures and employees who work in fear and become disengaged and unproductive, and the costs associated with dealing with these outcomes are both real and substantial. This research shows that organizations are generally ill-prepared to address destructive managerial behavior, and even those who have processes in place often falter in the execution. It is suggested that the act of developing corporate guidelines for dealing with destructive managerial behavior in advance will prepare the organization to minimize the damage that will be done to the company and its employees and permit priorities to be set based on company values

Un nuevo viaje de Teseo : De la Antigüedad a la Edad Media y al Renacimiento inglés

El presente trabajo propone explorar el modo cómo la literatura inglesa se apropia de la figura del héroe ático por antonomasia, Teseo, prefiriendo a las historias relacionadas con la aventura aquellas que lo muestran como figura garante del orden y de la sabiduría. Proponemos rastrear el modo cómo el héroe es presentado en el "Cuento del caballero" de los Canterbury Tales, representando no sólo el discurso patriarcal sino y, al mismo tiempo, quien desata las contiendas y quien las re-ordena. En este sentido, la figura del cuento- épico en el sentido bajtiniano del término- testimonia el discurso del orden, donde el varón es el eje vertebrador de la sociedad civil y familiar. Shakespeare, que había tomado contacto con las fuentes clásicas y medievales-tanto italianas como inglesas- incorpora en su Sueño de una noche de verano a un nuevo Teseo, que no sólo discurre acerca de la imaginación sino que también retoma la idea de orden a partir de la proclama de que es necesario someter las trampas de la imaginación a la prueba de la "fría razón". A partir de estos dos ejemplos, trataremos de reflexionar el modo cómo la literatura inglesa se apropió de estos mitos clásicosThe present article tries to illuminate the ways in which English literature configures appropriation of Athenian hero, Theseus, showing him as a model of order, reason and legality. We trace the ways in which the hero is represented both in Canterbury Tales 'and in Midsummer' Night Dream. These representations allow us to verify the negotiations between Medieval and Renisance's representations. Both Chaucer and Shakespeare try to strike a careful, though also playful, balance between "cool reason" and the dangers of the irrational and, in this way go a long distance from Plutarch's or Ovide's Theseus. They also depart from classic mythFil: Featherston, Cristina Andrea. Universidad Nacional de La Plata. Facultad de Humanidades y Ciencias de la Educación; Argentina

User Guide: A Guide to Disability Statistics from the National Assessment of Educational Programs (NAEP)

Policymakers, service providers, disability advocacy groups and researchers use disability statistics for a wide variety of purposes. A common problem that these groups encounter is finding a data source, a disability definition and/or a statistical method that provides them with a disability statistic that is both relevant to their needs and useful. The mission of the Cornell StatsRRTC is to bridge the divide between the sources of disability data and the users of disability statistics. One product of this effort is a series of User Guides to national survey data sets that collect information on the disability population. The purpose of each of the User Guides is to provide disability data users with: 1. An easily accessible guide to the disability information available in the nationally representative survey; 2. Estimates of the population with a disability, the disability prevalence rate, and estimates of participation-related statistics; 3. A description of the unique features of the dataset that will help disability statistics users determine whether the dataset can provide them with the statistic that they need; and 4. A description of how the dataset compares to other national data that are used to describe the population with disabilities. This User Guide contains information on the National Assessment of Educational Programs (NAEP), also known as “the Nation\u27s Report Card.” Unlike the other data sources addressed by the User Guide Series, the NAEP focuses solely on children. As a result, the focus of this Guide will shift to the inclusion and accommodation of educational activities of children with disabilities, as opposed to adult employment and economic well-being, which are the focus of many of the other User Guide
