Radio Resource Management (RRM) algorithms are needed to guarantee Quality of Service (QoS), to maintain the planned coverage area, and to offer high capacity. The family of RRM algorithms can be divided into Handover Control, Power Control, Admission Control, Load Control and Packet Scheduling functionalities. Using the existing RRM algorithms in 3rd Generation (3G) Cellular Networks supportin...

The objective of this study was to investigate genetic merit of return over feed (ROF), which is a herd profit index defined by CanWest Dairy Herd Improvement as a difference between milk income and feed cost. A multiple-trait (MT) model and random regression model (RRM) were used. The traits analyzed in MT were rearing cost and ROF of the first three lactations. In RRM, a cumulative ROF was fi...

OBJECTIVES To examine if the occurrence of different cancers was increased among rubber workers, as the highest known exposures of humans to nitrosamines have occurred in the rubber industry. METHODS A cohort of 8933 rubber workers (hired after 1 January 1950, still active or retired on 1 January 1981 and employed for at least 1 year in one of five study factories) was followed up for mortali...

In wireless and mobile communications, this progress provides opportunities for introducing new standards and improving existing services. Supporting multimedia traffic with wireless networks quality of service (QoS). In this paper, a grey-fuzzy controller for radio resource management (GF-RRM) is presented to maximize the number of the served calls and QoS provision in wireless networks. In a ...

RNA binding proteins are involved in many aspects of RNA metabolism. In Trypanosoma brucei, our laboratory has identified two trypanosome-specific RNA binding proteins P34 and P37 that are involved in the maturation of the 60S subunit during ribosome biogenesis. These proteins are part of the T. brucei 5S ribonucleoprotein particle (5S RNP) and P34 binds to 5S ribosomal RNA (rRNA) and ribosomal...

Frisbee, Jefferson C., John R. Falck, and Julian H. Lombard. Contribution of cytochrome P-450 v-hydroxylase to altered arteriolar reactivity with high-salt diet and hypertension. Am J Physiol Heart Circ Physiol 278: H1517–H1526, 2000.—The present study evaluated the contribution of cytochrome P-450 v-hydroxylase in modulating the reactivity of cremaster muscle arterioles in normotensive rats on...

Third generation mobile communication systems will allow many different services with varying demands on data rate and delay. For those systems, the fixed radio resource management (RRM) techniques used in today’s low rate systems will not be appropriate to ensure efficient utilization of the radio spectrum. Dynamic RRM is necessary in order to cope with the large variations in data rate. In th...

Vascular smooth muscle (VSM) transmembrane potentials (Em) were measured in situ in small branch arteries (150-300-microns o.d.), small branch veins (300-400-microns o.d.), arterioles (90-150-microns o.d.), and venules (80-250-microns o.d.) in the mesenteric and gracilis muscle and the arterioles and venules of cremaster muscle vascular beds in anesthetized rats with reduced renal mass hyperten...

Human La protein has been implicated in facilitating internal ribosome entry site (IRES)-mediated translation of hepatitis C virus (HCV). Earlier, we demonstrated that the RNA recognition motif (RRM) encompassing residues 112 to 184 of La protein [La (112-184)] interacts with the HCV IRES near the initiator AUG codon. A synthetic peptide, LaR2C (24-mer), derived from La RRM (112-184), retains R...

Glycine-rich RNA-binding proteins (GR-RBPs) are involved in cold shock response of plants as RNA chaperones facilitating mRNA transport, splicing and translation. GR-RBPs are bipartite proteins containing a RNA recognition motif (RRM) followed by a glycine-rich region. Here, we studied the structural basis of nucleic acid binding of full-length Nicotiana tabacum GR-RBP1. NMR studies of NtGR-RBP...
