Titanium is a highly reactive metal so that a thin layer of oxide forms on its surface whenever exposed to the air or other environments containing oxygen. This layer increases the corrosion resistance of titanium. The oxide film is electrochemically formed through anodizing. In this study, anodizing of titanium was performed in phosphate-base solutions such as H3Po4, NaH2Po4, and Na2Hpo4 at 9....

objective(s):previous studies demonstrated a functional similarity between vertebrate and honey bee nervous systems. the aim of the present study was to compare the effects of heroin and iranian street kerack, a combination of heroin and caffeine, on sensory threshold and locomotor activity in honey bees. materials and methods: all drugs were given orally to honey bees 30 min before each experi...

background the use of glycemic thresholds for diabetes diagnosis is controversial. however, no information is available regarding glycemic and glycated hemoglobin (hba1c) thresholds for detecting diabetic retinopathy (dr) in the iranian population. objectives the main purpose of the current investigation was to examine the association of fasting plasma glucose (fpg) and hba1c levels with diabet...

at the highest signal levels, the masking function for the off-frequency condition seems to become more linear. while some basilar membrane data show more linear growth at high levels, others do not. aim of the present study is to assess function of masking at high levels regarding its clinical appearance. in this experiment we evaluated the hearing thresholds of three different signals (wide-b...

The surface code scheme for quantum error correction holds great promise with relatively high error rate thresholds predicted some three orders of magnitude higher than conventional quantum error-correcting codes (such as the Steane code). The central problem is the question of how to physically implement the surface code in viable physical qubit systems. This report details the calculation of ...

This paper studies a dynamic matching market with two-sided private information bilateral bargaining. The model is a private information replica of Mortensen and Wright (2002). There are two kinds of frictions: time discounting at the rate r and explicit search costs. A simple necessary and su cient condition on parameters for no market breakdown is obtained. This condition is the same regardle...
