the aim of this study is to assess cost-effectiveness of infliximab, compared with conventional treatments in patients with moderate to severe ulcerative colitis (uc) in iran. we developed an analytical decision model with a 5-year-time horizon to follow up 1000 hypothetical patients, in order to estimate treatment costs and outcomes. hypothetical patients, were individuals with moderate to sev...

background: helicobacter pylori may cause many gastrointestinal problems in developing countries such as iran. we aimed to analyze the cost- effectiveness and cost- utility of the test-and-treat and empirical treatment strategies in managing helicobacter pylori infection.            methods: this was a markov based economic evaluation. effectiveness was defined as the symptoms free numbers and ...

This dissertation examines the semantic underpinnings of argument realization. Much recent work in argument realization is based on some notion of “prominence preservation,” wherein the morphosyntactic prominence of an argument in the clause (e.g. its grammatical relation) supposedly reflects its prominence in the meaning of the clause. I explore prominence preservation as it applies to crossli...

i am going to assess shortcomings of transaction cost economics (tce) of oliver williamson. my argument is that this analysis suffers from misidentification of the relevant problem of the theory, analytical incoherence, inconsistent empirical support and methodological defects. in formulating coase's fundamental idea, williamson accepts an efficient equilibrium which occurs once forever, t...

The paper contributes to techno-economic modelling of CO2 capture process in coalfired power plants. Technological options of CO2 capture have been chosen and cost estimation relationships (CERs) for the chosen options provided. The CERs are being fitted into a developed overall model of carbon capture and sequestration. Functions relating capital costs, operation and maintenance costs and tota...

Joux’s multicollision attack is one of the most striking results on hash functions and also one of the simplest: it computes a k-collision on iterated hashes in time ⌈log2 k⌉ · 2 , whereas k! · 2 was thought to be optimal. Kelsey and Schneier improved this to 3 · 2 if storage 2 is available and if the compression functions admits easily found fixed-points. This paper presents a simple technique...
