Samples (blood or tissue fluid) from 405 red foxes (Vulpes vulpes) from Finnmark, Northern Norway, were assayed for antibodies against T. gondii using the direct agglutination test (DAT). The proportion of seropositive animals was 42.5 %, with no significant relationship between sex and infection. The proportion of seropositives seemed to increase with age, in agreement with findings in previou...
In an attempt to understand the relationship between quasi-static and dynamic test results, repeatable, dynamic rollover tests were conducted on production vehicles to determine intrusion and intrusion velocities using the Jordan Rollover System (JRS). These tests included complete production vehicles and body bucks at reduced weight, to vary the roof strength-to-weight ratio. Data from these t...
Vibrating components are highly susceptible to fatigue failure. Fatigue occurs through long term exposure to time varying loads which although modest in amplitude give rise to microscopic cracks that steadily propagate to failure. Most components must fulfil some form of durability certification test prior to production. Tests are conducted on real prototype components or use a CAE based simula...
We propose a new adequacy test and a graphical evaluation tool for nonlinear dynamic models. The proposed techniques can be applied in any setup where parametric conditional distribution of the data is specified, in particular to models involving conditional volatility, conditional higher moments, conditional quantiles, asymmetry, Value at Risk models, duration models, diffusion models, etc. Co...
Lanyards are still important and common components of personal systems protecting against falls from a height. Experience with dynamic strength tests of lanyards indicates that test methods based on EN and ISO standards do not make objective assessment possible. This paper presents the results of theoretical and laboratory investigations of the performance of adjustable lanyards during fall arr...
Two approaches have generally been used to assessing liver function: one is to measure the products of liver synthesis, the other is to monitor hepatic clearance function. The exogenous dyes that can be used to study liver function are sulphobromophthalein (BSF) and indocyanine green (ICG). One valuable way to measure hepatic function is to use non-toxic substances (stains, sugar, drugs) that a...

در این پایان نامه رنگ آمیزی دینامیکی یک گراف را بیان و مطالعه می کنیم. یک –kرنگ آمیزی سره ی رأسی گراف g را رنگ آمیزی دینامیکی می نامند اگر در همسایه های هر رأس v?v(g) با درجه ی حداقل 2، حداقل 2 رنگ متفاوت ظاهر شوند. کوچکترین عدد صحیح k، به طوری که g دارای –kرنگ آمیزی دینامیکی باشد را عدد رنگی دینامیکی g می نامند و آنرا با نماد ?_2 (g) نمایش می دهند. مونت گمری حدس زده است که تمام گراف های منتظم ...
