Aims and Background: Propofol is one of the newest and the most common drugs in anesthesia and intensive care unit which is used to produce sedative effects. One of its complications is the pain produced at the time of injection. The aim of this study is to compare the pain of Propofol injection with two techniques: Propofol mixed with lidocaine and Propofol injection after lidocaine. Materials...
Embedded systems are suggestive targets for code injection attacks in the recent years. Software protection mechanisms, and in general computers, are not usually applicable in embedded systems since they have limited resources like memory and process power. In this paper we investigate side channel characteristics of embedded systems and their applicability in code injection attack detection. T...
The objective of this study was to consider effect of three different time of starting Ovsynch after Artificial Insemination, on synchrony parameters, pregnancy loss and fertility in Holstein cows. Multiparous cows (> 30 Kg/d, n = 450) randomly assigned to one of three groups. Groups according to time of starting Ovysnch were as follows: 1- Starting Ovsynch on day 25 after AI, 2- Starting Ovsyn...
Time-dependent injection can cause non-linear cooling effects, which lead to a faster energy loss of the electrons in jets. The most obvious result is the appearance of unique breaks in the SED, which would normally be attributed to a complicated electron distribution. Knowledge of the observation time and duration is important for the interpretation of the observed spectra, because of the non-...
One of the key questions to understanding the efficiency of diffusive shock acceleration of the cosmic rays (CRs) is the injection process from thermal particles. A self–consistent injection model based on the interactions of the suprathermal particles with self–generated magneto–hydrodynamic waves has been developed recently by Malkov (1998). By adopting this analytic solution, a numerical tre...
In order to combat code injection attacks, modern operating systems use among others, the Write-XOR-Execute (W⊕X) countermeasure which disallows code execution from writable memory pages. Unfortunately though, a widely used programming technique, namely Just-in-time compilation (JIT), clashes with the use of this countermeasure since its use relies on writable memory where it places dynamically...
In this paper, injection-locked MESFET oscillators are analyzed using several numerical models. The injectionlocking behavior of the van der Pol equation and of a more complex representation using the Curtice–Cubic MESFET model are investigated. Analysis and experimental results are compared for an NE71083 transistor oscillator operating at 0.5 GHz. The deficiencies of using a van der Pol oscil...
Calcium ions were iontophoretically injected into ventral photoreceptors of Limulus by passing current between two intracellular pipettes. Changes in sensitivity and photoresponse time course were measured for both light adaptation and Ca++ injection. We found for some photoreceptors that there was no significant difference in the photoresponse time course for desensitization produced by light ...
this study was performed to evaluate the efficacy of injection of essential oil of eugenia caryophyllata in the kid horn buds, as a new chemical technique for disbudding. five-day-old healthy goat kids from both sexes (n = 16) were divided randomly into 4 equal groups. in groups 1, 2 and 3, 0.2 ml of clove essence and in group 4 (control) 0.2 ml of normal saline was injected into the left horn ...
