The aim of this research was the replacement conventional sample extraction techniques for polycyclic aromatic hydrocarbons (PAH) in tissue samples a reliable, fast and ecofriendly procedure. method developed using pressurized solvent assessing two different standard reference materials (fish mussel) freeze-dried fortified sardine (Sardinella sp.). Five procedures were evaluated best performanc...

background: the objective of this work was developing a simple and stable time-based on-line setup for assessing the potential of mercury (hg) vapor adsorption of the commercial sorbents used in air sampling and control operation followed by cold vapor atomic absorption spectrometry (cvaas). methods: a special designed separation chamber was used where reduction of the injected hg (ii) solution...

We present a formal veriication of the transient fault recovery aspects of the Reliable Computing Platform (RCP), a fault-tolerant computing system architecture for digital ight control applications. The RCP uses NMR-style redundancy to mask faults and internal majority voting to purge the eeects of transient faults. The system design has been formally speci-ed and veriied using the Ehdm veriic...

Endoscopic discectomy entails use of an imaging-guided probe inserted between the vertebrae and into the herniated disc space. Microsurgical attachments routed through the endoscope remove a portion of the nucleus tissue of the compromised disc; the amount excised depends on various circumstances but never affects the disc’s support structure. It is also possible to use the instrument to manipu...

RRDtool is a circular database that stores time series data. RRD tool assumes time-variable data inintervals of certain length. An interval named as step, and specifiedupon creation an file which cannot be changed afterward. Because datamay not always come at just the right time, will automaticallyinterpolate any submitted This done to fit its internal timestamps. Ifwe compare linear databases ...

This study evaluated effects of four uniquely applied beef carcass electrical stimulation (ES) treatments on USDA grade factors, muscle color, subprimal purge loss, cooked steak weight loss, and cooked steak tenderness. One side of each (n = 284) beef carcass was subjected to ES using one of four treatments (medium voltage for medium duration, MVMD; medium voltage for long duration, MVLD; high ...

Current approaches to personalizing online advertisements rely on estimating user preferences from server-side logs of accumulated user behavior. In this paper, we consider client-side ad personalization, where user-related information is allowed to be stored only within the user’s control (e.g., in a browser cookie), enabling the user to view, edit or purge it at any time. In this setting, the...

We present three experiments on horizon estimation. In Experiment 1 we verify the human ability to estimate the horizon in static images from only visual input. Estimates are given without time constraints with emphasis on precision. The resulting estimates are used as baseline to evaluate horizon estimates from early visual processes. Stimuli are presented for only 153 ms and then masked to pu...

ABSTRACT This article applies a regime cycle framework to understand patterns of change and continuity in African competitive autocracies. We observe that autocracies is rarely the result actions carried out by rebels, opposition leaders or popular masses substantially altering structure power. Instead, they are more frequently senior cadres, resulting controlled reshuffles argue such shifts be...
