experimental infection of muscovy ducks with v4 strain of newcastle disease virus was undertaken to determine the response of the ducks to the virus and the possibility of virus transmission to ducks and chickens in village like conditions. twelve ducks were randomly and equally divided into three groups of control, inoculated and in-contact. additionally, the chickens were placed into two grou...

Twenty-four episodes of genital herpes in 22 men, all confirmed by virus isolation, were studied in a double blind trial. They were treated either with 3% adenine arabinoside (Ara-A) in petrolatum ointment base or with the base alone applied four times daily for one week. The lesions were counted and sketeched on days 0, 2, and 7. There was no demonstrable advantage to be gained from the use of...

The IETF has standardized Transparent Interconnection of Lots of Links (TRILL), a protocol for least-cost transparent frame routing in multi-hop networks with arbitrary topologies and link technologies, using link-state routing and a hop count. The TRILL base protocol standard supports the labeling of TRILL Data packets with up to 4K IDs. However, there are applications that require a larger nu...

In this paper the semi-active control is achieved by a base isolation system. The magnetorheological dampers (MRD) hysteretic force is described by models based on nonlinear differential equation Bouc-Wen. The Bouc-Wen model is able to capture, in an analytical form, a range of shapes of hysteretic cycles which match the behavior of a wide class of nonlinear systems. In order to reduce the seis...

People with psychotic disorders frequently experience significant mental and social limitations that may result in persisting social isolation. Research has shown that a supportive social environment is crucial for the process of personal recovery. Peer support groups can provide an opportunity to reduce isolation and enhance the process of personal recovery. It encourages people to express the...

Abstract. Monuments and museums contents in the Mediterranean area have revealed a poor dynamic behavior suffered large damages during past severe seismic events. Their protection deserved great research efforts due to their inestimable values high cultural significance. From an analytic point of view, art museum objects, statues displays are generally modelled as rigid blocks been extensively ...

The POWER4-based p690 systems offer the highest performance of the IBM eServer pSeries line of computers. Within the general-purpose UNIX server market, they also offer the highest levels of concurrent error detection, fault isolation, recovery, and availability. High availability is achieved by minimizing component failure rates through improvements in the base technology, and through design t...

Web browsers ostensibly provide strong isolation for the client-side components of web applications. Unfortunately, this isolation is weak in practice; as browsers add increasingly rich APIs to please developers, these complex interfaces bloat the trusted computing base and erode cross-app isolation boundaries. We reenvision the web interface based on the notion of a pico-datacenter, the client...

We develop a method for estimating the rivalness of tax bases using the structures of the conditional logit, Poisson and nested logit models. As an illustration, we apply this method to estimate the e↵ect of state-level capital taxation on U.S. inward foreign direct investment. The assumption of perfect non-rivalenss can in some cases be rejected, but the assumption of perfect rivalness cannot....

Understanding the genetic basis of reproductive isolation between recently diverged species is a central problem in evolutionary genetics. Here, I present analyses of the genetic architecture underlying hybrid male sterility and segregation distortion between the Bogota and USA subspecies of Drosophila pseudoobscura. Previously, a single gene, Overdrive (Ovd), was shown to be necessary but not ...
