Monitoring disturbances in process dispersion using control chart is mostly based on the assumption that quality characteristic follows normal distribution, which not case many real-life situations. This paper proposes a set of new charts homogeneously weighted moving average (HWMA) scheme, for efficient detection shifts standard deviation (σ). These are variety σ estimators and investigated as...

We have studied the influence of temperature and ARL 67156 on ATP hydrolysis in mouse and guinea pig vas deferens in order to explore the properties of the enzymatic inactivation mechanism proposed to regulate purinergic neurotransmission at the sympathetic neuromuscular junction of smooth muscle. The ectonucleotidase activity was determined by using the malachite green method to measure the in...

AIDS-related lymphomas (ARL) present high biological heterogeneity. For better characterization of this type of lymphoma, the objectives of the present study were to evaluate the expression of immunohistochemical markers of cell differentiation (CD10, Bcl-6, MUM-1) and determine cell origin profile according to Hans' classification of diffuse large B-cell lymphoma in AIDS patients. This study i...

Post-translational modification with myristoyl or prenyl groups is essential for membrane association of many small GTPases in the Ras superfamily. Two recent papers show that, rather than myristoylation, amino-terminal acetylation of the Arf-like protein Arl3p is required for Golgi targeting via an interaction with an integral membrane protein called Sys1.

The Extended Exponentially Weighted Moving Average (extended EWMA) control chart is one of the charts and can be used to quickly detect a small shift. performance evaluated with average run length (ARL). Due deriving explicit formulas for ARL on two-sided extended EWMA trend autoregressive or AR(p) model has not been reported previously. aim this study derive as well AR(1) AR(2) models exponent...

Several left-right parity violating asymmetries in lepton-lepton scattering in fixed target and collider experiments are considered as signals for doubly charged vector bosons (bileptons). ∗Presented by M.

The Hy-V project will conduct the first-ever mode-transition flight-test for a dual-mode hypersonic scramjet, which will occur at approximately 90,000 feet onboard a sounding rocket. At altitude, atmospheric conditions and inlet flow speed will match the flow conditions simulated in the UVA Aerospace Research Laboratory (ARL) hypersonic wind tunnel. Geometric similarity between the wind tunnel ...
