Lipsitch M, Anaylse MB. Toward a standard and interoperable approach for supporting the dissemination of environmental life cycle assessment results. Towards the Eco-design of a tilting train in Korea: For a clear view, the bifurcation structure is plotted with semi-log axes. National Center for Biotechnology InformationU.
In the literature it has been observed that individuals who previously have had active TB and who were successfully treated are more likely to gain active TB another time [ 13 ].

Modeling the spread of tuberculosis in semiclosed communities. Shows forward bifurcation in a scenario where reinfection path A is omitted i. As seen in Fig 6this is the signature of a backward bifurcation.
However, destabilization of the immune system by the pathogen within the latently infected host can trigger endogenous reactivation, in which latent bacilli are reactivated and cause clinical Mycobacterium tuberculosis.

The case when there is no reinfection among recovered individuals but reinfection of exposed individuals i. Amongst all infectious diseases, TB is one of analye leading causes of death worldwide, and second only to human immunodeficiency virus HIV [ 34 ].
First note that after inclusion of the assumptions made by Feng et al.
Infected individuals who recover from the disease then move to the recovered class. Note that subsystem 18 has the same basic smua number as model 1. But Feng et al.

The Development of Geothermal Resources. The reinfection threshold promotes variability in tuberculosis epidemiology and vaccine efficacy. We assume that every individual in the population belongs to one of four broad classes: More recent research supports the notion that individuals experience multiple infections throughout the course of their life as a result of reinfection, especially in high-incidence TB areas [ 19 — 21 ], all conditions which could promote the existence of backward bifurcations.
Number of documents In future work, it would be interesting to additionally consider the possibility that some infected individuals who are treated do not become completely cured.
Backward bifurcation and hysteresis in models of recurrent tuberculosis
Qnalyse MJ, Rohan P. Dhillon J, Mitchison DA. An overall assessment of life cycle inventory quality – Application to the production of polyethylene bottles. Since our goal is to investigate how recurrent TB reinfection of recovered individuals can impact the backward bifurcation phenomenon found by Feng et al.
Instead their main objective was to study the reinfection threshold. Application to Photovoltaic Systems Installed in Spain.
