چکیده
Introduction When it comes to a fast, non-intrusive, complete and meaningful inspection of an offshore pipeline in-line inspection (ILI) has been the method of choice for several decades now. However, not all pipelines, piping or other tubular structures can be inspected with in-line inspection tools (pigs). The method is usually limited to looping flow lines or export pipelines, specifically designed for ILI operation. The remaining structures are often summarized under the buzzword “non-piggable”.

Integrated visualization for geometry PIG data
The geometry PIG is a system that can inspect the inside of a pipeline. The amount of pigging data is usually considerable because the system records multi-channel sensor values for a long distance inspection. Therefore, the efficient visualization of geometry PIG data is essential for the operator to analyze the amount of sensor data and to assess the pipeline features and conditions within a ...
متن کاملTracing the Pig and Cattle Origin in Processed Food and Feed Products Targeting Mitochondrial 12S rRNA Gene
Background: Species identification in commercially processed food and feed products is one of the important issues. This study was conducted to develop a genetic method for the detection of pig and cattle species in processed food and feed products using newly designed species-specific primers targeting mitochondrial 12S rRNA gene fragments. Methods: Two sets of specific primers were designed ...
متن کاملTrichinella britovi as a risk factor for alternative pig production systems in Greece and Europe
Trichinellosis is an important zoonosis and the most common source of human infection is meat from pigs and wild boars. The European Union (EU) supports alternative pig production systems (organic and free-ranging) as sustainable farming systems. However, these systems that allow outdoor access for farm animals, may create new or reintroduce old risks to public health. During the last years, al...

A frican swine fever (ASF) is one of the most severe viral pig diseases. Some genotypes can cause up to 100 percent mortality in pigs and wild boar, such as the genotype II virus introduced into Georgia in 2007 (Chapman et al., 2011), which spread throughout the Caucasus (Beltran-Alcrudo et al., 2008) into the Islamic Republic of Iran (Rahimi et al., 2010), the Russian Federation (BeltranAlcrud...
