As part of the U.S. EPA’s Lake Michigan Mass Balance Study, a predictive model for gas-phase persistent organic compounds over Lake Michigan has been constructed. Using air temperature, wind direction and atmospheric PCB concentration collected around and over the lake, the model predicts the concentration of PCB congeners (~100) and trans-nonachlor over the lake and gas exchange fluxes. The mo...

In this study, the genetic diversity of three milk protein genes namely beta-casein, kappacasein and beta-lactoglobulin was estimated in Turkish cattle breeds. Based on these genes, breeds in Turkey have been grouped as: 1) Eastern Anatolian Red, Anatolian Black and Southern Anatolian Red and 2) Turkish Grey, Turkish Holstein and Holstein Candidate Bulls. B alleles of the three studied genes, w...

With the rapid construction of long-distance oil and gas pipelines, big pipeline network was gradually formed in China and its surrounding areas, therefore the management of pipeline production becomes increasingly complicated and difficult. In this paper, we propose a data model for pipeline production to support the planning, scheduling, distribution, metering, energy consumption, process tec...

Medical gases can be identified simply if they are supplied at different pipeline pressures. Routine maintenance errors, accidental pipeline cross-connections, or gas failures, can be automatically detected by incorporating a pneumatic unit with pressure-sensitive valves into the anaesthetic machine. A fail-safe method of ensuring the delivery of the correct gases to the patient is described.

With the rapid increase in oil and gas consumption in the world’s energy consumption structure, the pace of global oil–gas pipeline construction has accelerated. Pipeline accidents that cause huge economic losses occur frequently, so inspection and maintenance of oil and gas pipelines have become critical issues. This paper presents a helical-contact deformation measuring method based on a mult...

Girth weld cracking is one of the main failure modes in oil and gas pipelines; girth weld cracking inspection has great economic and social significance for the intrinsic safety of pipelines. This paper introduces the typical girth weld defects of oil and gas pipelines and the common nondestructive testing methods, and systematically generalizes the progress in the studies on technical principl...

The Trans-ASEAN Gas Pipelines was a project of interconnected cross-border pipelines connecting ASEAN countries in bilateral manner based on the cooperation stipulated Memorandum Understanding Pipelines. This paper will identify with two (two) models already practised worldwide, namely model and unified model. method used this article normative juridical, including comparative approach statute ...
