Multiple defense systems

Hybrid Combination of overpressure and ventilated-facepiece system. Flexibility. Lenghty inside occupation. Emergency entry and exit movements. Armored fighting vehicles (tanks). Helicopters. Air defense. Multiple launcher rocket system. 

In chemical industry infrastructure security, protection in depth is used to describe a layered security approach. A protection-in-depth strategy uses several forms of security techniques and/or devices against an intruder and does not rely on one single defensive mechanism to protect infrastructure. By implementing multiple layers of security, a hole or flaw in one layer is covered by the other layers. An intruder will have to intrude through each layer without being detected in the process—the layered approach implies that no matter how an intruder attempts to accomplish his goal, he will encounter effective elements of the physical protection system. 

Infection 1. Invasion and multiplication of microorganisms in body tissues, which may be clinically unapparent or result in local cellular injury due to competitive metabolism, toxins, intracellular replication, or antigen-antibody response. The infection may remain localized, subclinical, and temporary if the body s defensive mechanisms are effective. A local infection may persist and spread by extension to become an acute, subacute, or chronic clinical infection or disease state. A local infection may also become systemic when the microorganisms gain access to the lymphatic or vascular system. 2. An infectious disease. [EU]... 

The induction of liver enzymes has been demonstrated in many species, including humans, and probably represents a homeostatic, defense mechanism. Induction usually requires multiple exposures to the inducing agent over a period of several days, the time required for the synthesis of new protein. Enzymes induced include the cytochrome P450 monooxygenase system glucuronyltransferase the microsomal ethanol oxidative system and the steroid-metabolizing system. 

Accelerated Mice (SAM) line being characterized by accelerated rate of accumulation of senescence features and essential (approximately two-fold) shortening of lifespan in relation to the animals of the control line [99]. SAM mice are characterized by multiple defects in the system of anti-oxidant defense and increased level of chromosomal aberrations in the stem cells [99,100]. Every day use of camosine by the animals of this line (100 mg/kg body weight) results in deceleration (or reversion) of senescence, increase in average lifespan (approximately by 20%) as well as favored the exterior of the animals [101-103].
