Microscopic lens thermography for the observation of features in light cardboard
نویسندگان
چکیده
This is a preliminary study for microscopic lens thermography observations on a film-like and non-blackbody material. With this aim, a number of features present on the surface of a cardboard for storage boxes (grammage 300 g/m2) are observed using a Flir SC 3000 thermal imager microscopic lens with 26 mm fixed focal distance. Comments on quality of observation and on probability of false indications depending on on the depth of the features observed are supplied, in particular concentrating on transient time for observation during cooling following illumination and on thermal gradients measured.

Cells are active components in their environment and constantly adjusting their performance to improve extracellular milieu changing. This approach is reflected their tends of maintaining intracellular homeostasis.

Background: Whenever the balance between Antioxidants and reactive oxygen species (ROS) is disrupted towards an overabundance of ROS, oxidative stress (OS) occurs. There is evidence that glutathione as an intracellular antioxidant plays an important role against ROS in female reproductive system. BSO is a selective inhibitor of glutathione peroxidas. The aim of the present study is to investiga...

White Spot Disease (WSD) is well known as a widespread viral disease in shrimps from 1992. Many studies focused on morphological, histopathological and epidemiological characteristic and pathogenecity of the disease but less on the determination of the severity of WSD using the histopathological features in target tissues. A generalized scheme for assigning a numerical qualitative value to sev...
