A study of the structure of the terminal part of the T-tubule system and the distribution of sub8arcolemmal caveolae was undertaken in guinea-pig psoas muscle. The results were correlated with the array of cell surface features as revealed by frozen-etched, shadowed replicas of the cell membrane. Freeze-etching revealed numerous small rounded objects overlying the Zand I-bands and the A-I junct...
Background: The injection of retrobulbar block is associated with significant pain and discomfort. Therefore a short-acting IV analgesic before retrobulbar injection has been advocated. Objective: To compare remifentanil, alfentanil and fentanyl in providing analgesia for retrobulbar block injection. Methods: 69 patients were enrolled randomly into three groups of 23 each to receive either Remi...
Primary hydatid disease of the spleen is rarely reported. We describe the first report of primary hydatid disease of the spleen which was diagnosed by ultrasonography-guided fine needle aspiration (FNA). A 25-year-old female from Fars province, Iran, presented with left flank pain one week prior to admission. Abdominal ultrasonography showed a large cystic lesion, 8 cm in diameter at the spleni...
Deep photometric data in the V-, R-, I-, zand K-bands for the cluster of galaxies EIS 0048-2942 are used to investigate the properties of the galaxy populations at z ∼ 0.64 in a field of 2.5 × 2.5 Mpc. The sample of candidate cluster members (N = 171) is selected by the photometric redshift technique and is complete up to I = 22.5. Galaxies were classified as spheroids and disks according to th...
Ecosystem services are benefits that people obtain from ecosystems. Soil retention is one of the most important ecosystem services. The capacity of ecosystem to maintain soil can be estimated by quantifying this services. In this study, version 3.0.0 of the InVEST software was used to map this ecosystem service in the eastern part of Gorgan-Rud watershed. The InVEST model employs the Universal ...
SiGe technology is sincerely challenging III/V and II/VI technologies in the realm of high frequency electronics applications, for example optical fibre and mobile communications. In this paper a model of SiGe HBT with uniform impurity doping in the base for high frequency application is studied. The high frequency parameters are extracted with the help of simulated Zand Yparameters of two port...
In recent work [1], a simplified and highly effective approach to speaker recognition based on the cosine similarity between lowdimensional vectors, termed ivectors, defined in a total variability space was introduced. The total variability space representation is motivated by the popular Joint Factor Analysis (JFA) approach, but does not require the complication of estimating separate speaker ...
Abstract Having local data communication (without global broadcast of signals) among the elements is important in very large scale integration (VLSI) designs. Recently, 2-D systolic digital filter architectures were presented which eliminated the global broadcast of the input and output signals. In this paper a generalized formulation is presented that allows the derivation of various new 2-D V...
