Respiratory system description

When examining the technical and scientific evolution of the respirator, the question of original invention inevitably arises. As Galarraga points out, while it is very likely that human beings used makeshift masks for thousands of years to protect their eyes, mouths and respiratory systems from smoke and dust, the first detailed description of a protective mask is usually credited to Leonardo da Vinci in the early 1500s.80 Ironically,... 

Chapter 11 presents models used to study the continual interaction of the respiratory mechanical system and pulmonary gas exchange. Traditionally, the respiratory system is described as a chemo-stat — ventilation increases with increased chemical stimulation. Alternatively, the author proposes that quantitative description of the respiratory central pattern generator, a network of neuronal clusters in the brain, is a much more sophisticated and realistic approach. Study of this dynamic, optimized controller of a nonlinear plant is interesting from both physiological and engineering perspectives, the latter due to applications of these techniques for new, intelligent control system design. 

This chapter first provides a description of immunity in general and then more specifically, immunity in the mucosal immune system. The immune response of both intestinal and respiratory tracts will be described in detail as these are the two most common portals of targeted vaccine development for mucosal immunity. The chapter will cover the basis of mucosal immunity using plant-based oral vaccines. Strategies for increasing mucosal immunity, such as the use of adjuvants, will also be discussed. Finally, the chapter will cover the precliiucal tests and various cliiucal trials that are taking place with respect to production of human and veterinary therapeutic proteins in plants. 

The description of C02-diffusion in leaves by Fick s law in the form of Eq. (8b) is convenient because it allows the use of electrical analogue models. In this way the process of C02 diffusion can be described by a series of resistances. However, the external C02 is not the only C02 source for the C02 fixing enzyme system because within the plant cells C02 is produced by respiratory processes (see 6.4.). Thus one obtains the circuit analogue pattern for C02 fluxes depicted in Fig. 4. Then, the net C02 flux from environment into leaves is given by ...

The description of respiratory mechanical system is based on lumped-parameter model [10] of Fig. 2 for the relation between respiratory neural P(t) and the mechanical outputs V(t), V(t) and the dynamical equation is given by ... 

Description of hazard. Water plant operators and associated maintenance staff are frequently exposed to various respiratory hazards, including dusts, chemical vapors, and gases. When engineering controls, such as general and local exhaust ventilation systems, are not adequate to control the hazard, workers must be required to use respiratory protection. Emergency procedures may also require the use of emergency escape or self-contained respiratory protective equipment.
