To repair corroded subsea pipelines, composite fiber-reinforced polymer (CFRP) patches are often attached to the defected area. The aim of this paper is present a method assure if strength repaired pipelines sufficient enough sustain burst pressure loads. A computational model for predicting with CFRP presented. An algorithm artificial neural networks (ANN) applied. geometry corrosion damage de...

results under the above chromatography condition, biuret compound (peqb) and the internal standard were detected at 4.5 and 13.5 minutes, respectively. limit of quantitation of the peqb was 0.1 µg/ml. accuracy of the method over the concentration range of 0.1-100 µg/ml was between 88-109%. inter- and intraday precisions were 4-19% and 6-8%, respectively. a good relationship in the form of a pow...

background: this study was aimed to investigate the association of consuming white rice and potato, as well as the bread type with anthropometric measures and blood pressure (bp) in a national sample of iranian children and adolescents. methods: this nationwide study was conducted in 2011-2012 among 14,880 students, aged 6-18 years, selected by multistage cluster sampling from 30 provinces of i...

conclusions examination of the fasting lipid profile has clinical importance in predicting the efficacy of peg-ifn-α-2b plus rbv combination therapy for patients with hcv g1b even after the discovery of the il28 genotype as a potent predictive factor. objectives to re-examine the significance of lipoprotein profiles on virological response to peg-ifn plus rbv combination therapy in patients wit...

the quality of pressure distribution over the atmosphere of the sea level and geopotential altitude at different atmosphere layers affect on many climate and meteorology phenomena of the earth surface. one of the important meteorology phenomenon is the occurrence of frost phenomenon especially late spring frost. in this surrey, occurring late spring frost days and minimum temperature during the...

background: aflatoxin m1 (afm1) is a toxic compound that could be found in milk and dairy products. afm1 is the principle hydroxylated derivative of aflatoxin b1 (afb1), formed in liver and excreted into the milk in the mammary glands of both human and lactating animals that have been fed with afb1 contaminated diet. to the best of our knowledge, there is no report on stability of afm1 during p...

CO2 emissions due to massive industrialization have led several environmental issues. Carbon Capture and Storage (CCS) is one of the most important technologies that can be used reduce anthropogenic worldwide. CCS projects mainly involve three processes: carbon capture, transportation, storage. In transportation process, modeling flow in pipelines relationships between pressure, velocity, tempe...

As a result of the technical development agriculture, machines with very high axle loads appeared in fields and on farm roads. result, subsurface soil pressure values will also increase, which ultimately put increased stress underground pipelines other structures. In our paper, we show possibility modelling problem using explicit dynamical methods by means simple example.
