Permanent Pipe Lines for Dairy Plants

A Longitudinal Mode Electromagnetic Acoustic Transducer (EMAT) Based on a Permanent Magnet Chain for Pipe Inspection

A new electromagnetic acoustic transducer (EMAT) design, employing a special structure of the permanent magnet chain, is proposed to generate and receive longitudinal guided waves for pipe inspection based on the magnetostriction mechanism. Firstly, a quantitative analysis of the excitation forces shows the influence of the radial component can be ignored. Furthermore, as the axial component of...

Global opportunities in Pipe in Pipe technology

An extensive product range is mandatory to be a key player in the pipe insulation market. The polyurethane preinsulated pipe producers are responding to global opportunities by diversifying their activities into industrial, marine, oil and gas applications. Moreover, the requirements for traditional district heating preinsulated pipes including initial thermal conductivity and its ageing perfor...

Subpart B—General Specifications for Dairy Plants Approved for USDA Inspection and Grading Service1

All inspectors or graders are forbidden during the period of their respective appointments or licenses to take an active part in political management or in political campaigns. Political activities in city, county, State, or national elections, whether primary or regular, or in behalf of any party or candidate, or any measure to be voted upon, is prohibited.

Embryonic liver cells and permanent lines as models for hepatocyte and bile duct cell differentiation

Analysis of liver cells during development is facilitated by the possibility of complementing in vivo analysis with experiments on cultured cells. In this review, we discuss results from several laboratories concerning bipotential hepatic stem cells from mouse (HBC-3, H-CFU-C, MMH and BMEL), rat (rhe14321) and primate (IPFLS) embryos. Several groups have used fluorescence-activated cell sorting...
