Internal Foreign Bodies

Internal foreign bodies, that is, foreign bodies embedded in the food material, are a nightmare for food plant quality monitoring. Detection systems are generally based on X-ray, the absorbance of which depends on the atomic number and concentration of the material [151]. But very often. X-rays are not sensitive to intrinsic foreign bodies such as stem, pits, skin, or pieces or hair, because the tissues are not significantly different in their atomic number. 

In the applicahons described above (Sections 8.3.2 and 8.3.3), the contaminants were located on the surface or subsurface of the food product, or as separate bodies in a stream of other objects. Detection was mainly carried out on the basis of spectral absorption properties. Even more challenging is the detection of internal foreign bodies.

EN 60529 outlines an international classification for the sealing effectiveness of enclosures of electrical equipment against the intrusion into the equipment of foreign bodies (i.e., dust, tools, fingers) and moisture. This classification system utilizes the letters IP (Ingress Protection) followed by two digits. An X is used for one of the digits if there is only one class of protection i.e. IP X4 which addresses moisture resistance only. 

Accessory centres are commonly seen in the foot 50 have been described (Hoerr et al. 1962) but only 20 are common. An accessory navicular, os tibiale externum, is seen on the medial or internal aspect of the navicular in 10% of children, usually after the age of 5 and more often in girls (Drennan 1992). Another variant, the os intermetatarsale, commonly situated between the bases of the first and second metatarsals can be misdiagnosed as a foreign body. Accessory ossicles can be readily distinguished from fractures by their consistent anatomical location and smooth well corticated margins.

PLLA has been proved to be efficient and safe in the fixation of malleolar fractures [65] and syndesmosis [66]. Bostman reviewed 1223 patients between 1985 and 1994 who had malleolar fractures treated by internal fixation with bioabsorbable pins and screws [65]. The implants used were PGA, PLA, and their copolymer. Only 10 patients (0.8%) showed any side effects, which included various local foreign body reactions, synovial irritation, and subsequent degeneration. 

Phagocytosis of PS Based Particles One of the main defense mechanisms of the living system against foreign bodies (e.g. viruses and bacteria) is "phagocytosis", which is usually described as "the internalization of micron-size solid foreign materials by cells". In early studies, vital dyes, colloidal suspensions (i.e. carbon, iron oxide), etc. were utilized for visualization and quantitation of the phagocytic process (43). 

Turbulence is caused when the liquid flows from a larger area to a small-diameter pipe, as in the inlet ends of tubing in heat exchangers. Internal deposits in the pipes, or any obstruction to the flow inside a pipe by a foreign body, such as a carried-in pebble, can also cause turbulence.

We consider that the association processes 2X X2 with atoms have no activation barrier, as illustrated in Figure 12.3. With more complex species such as free radicals where the translational energy can be converted into energy of some internal modes, the de-energisation of X2 can occur without the need for termolecular collisions with a foreign body (such as an inert gas, M).
