Movements of Channel Catfish and Flathead Catfish in Beaver Reservoir, Northwest Arkansas

A total of 497 channel catfish, Ictalurus punctatus, and flathead catfish, Pylodictis olivaris. were tagged in Beaver Reservoir during two November-April tagging periods (1967-68 and 1968-69); total recaptures were 9.5 and 11.7% respectively. The longest time between tagging and recapture was 1622 days (4.4 years) for channel catfish and 494 days (1.4 years) for flathead catfish. The longest distances traveled were 43.1 km by a channel catfish and 44.3 km by a flathead catfish. Fisherman returns indicated that catfish were caught primarily from April through July. The many recaptures, even after long periods, within 1.6 km of the tagging point, suggested that fish moved little, or had homing tendencies. Captures of fish in trap nets indicated that rainfall and inflow possibly stimulated movements of channel catfish during the winter and early spring

Unlocking the potential of RNA interference as a therapeutic tool

The existence of an intrinsic biochemical pathway enabling specified regulation of gene expression was unheard of until the final years of the last decade. The identification of ribonucleic acid interference (RNAi) in mammalian cells has nowadays become of extreme importance in the field of functional genomics and translational medicine. The advent of RNAi technology has brought to the scientific research and pharmaceutical communities the ability to regulate expression of any desired gene in a reproducible manner. Consequently, such technology may be utilised in the design of novel therapeutics for clinical conditions having dys-regulated gene expression. Since most RNAi-based therapies in the drug development pipeline of pharmaceutical companies utilise short interfering RNA (siRNA), this review will focus on the role of siRNA in drug development.peer-reviewe

Following a Sigmoid Progression: Some Jurisprudential and Pragmatic Considerations Regarding Territorial Acquisition Among Nation-States

This article analyzes methods and doctrines used by States to acquire territories. The role of the United Nations in resolving disputes between nations and the inhabitants directly affected by the disputes is also addressed, including the jurisdictional, jurisprudential, and practical considerations of territorial acquisition. Finally, traditional territorial acquisition doctrines are applied to extraterrestrial and outer space acquisition. As Western civilization etched out territories and borders across its known world, international norms of diplomatic behavior appeared in the form of customs. These customs eventually grew into codifications, which in turn grew into the elaborate international system enjoyed and protested today. Laws emerged among international States to formalize the growing body of norms of interaction across them. Modern territorial sovereignty provides the State an “exclusive right” to perform State functions within that territory, but with a realization that no State may exercise its authority within the territorial limits of other States

Recent Advances in Synovial Fluid Analysis

Synovial fluid analysis is a frequently ignored examination except in suspected cases of septic conditions. It has been shown that it is an extremely valuable procedure in making rapid and accurate diagnoses in many types of joint diseases

Silicon web process development

Thirty-five (35) furnace runs were carried out during this quarter, of which 25 produced a total of 120 web crystals. The two main thermal models for the dendritic growth process were completed and are being used to assist the design of the thermal geometry of the web growth apparatus. The first model, a finite element representation of the susceptor and crucible, was refined to give greater precision and resolution in the critical central region of the melt. The second thermal model, which describes the dissipation of the latent heat to generate thickness-velocity data, was completed. Dendritic web samples were fabricated into solar cells using a standard configuration and a standard process for a N(+) -P-P(+) configuration. The detailed engineering design was completed for a new dendritic web growth facility of greater width capability than previous facilities

Low cost silicon solar array project large area silicon sheet task: Silicon web process development

Growth configurations were developed which produced crystals having low residual stress levels. The properties of a 106 mm diameter round crucible were evaluated and it was found that this design had greatly enhanced temperature fluctuations arising from convection in the melt. Thermal modeling efforts were directed to developing finite element models of the 106 mm round crucible and an elongated susceptor/crucible configuration. Also, the thermal model for the heat loss modes from the dendritic web was examined for guidance in reducing the thermal stress in the web. An economic analysis was prepared to evaluate the silicon web process in relation to price goals

Musculoskeletal Sarcoidosis and Rheumatoid Factor

Articular manifestations of sarcoidosis were present in 19 of our 60 patients (32%). This correlates with previously reported studies. In all of our cases but one, the articular manifestations subsided in eight weeks. This fact and the absence of hyperuricemia are in contradistinction to other studies for which we have no adequate explanation
