Indeed it is possible that HIV is having a double effect on TB control services in our communities; not only are there more TB cases and therefore increased transmission of disease, but also there is an increasing burden on over-stretched health services, making effective control harder to achieve [27].
Since the reproductive performance of these carrier animals is unaffected, they are retained in herds in Nigeria despite the presence of pathognomonic clinical signs in some cases, making effective control programmes extremely difficult.
The eco-exposome concept also captures the important link outward from the organism (i.e., human or other species) to single or multipollutant sources, which is critical in making effective control decisions.
The Affordable Care Act makes effective birth control more affordable for millions of women by requiring employer-based health plans to include no-cost coverage for contraceptives.
Current proposals wouldn't establish effective control.
In addition, the high-frequency induction heating method has less influence on the work environment, is easier to control, and makes effective use of the space possible than other methods.
For instance, the information on security margins of each feeder can be obtained, thus, dispatchers can obtain the global information of the system by DSSR visualization technology to make effective preventive control decisions.
Rigorous analysis of the model shows that the assumed imperfect nature of quarantine (in preventing the infection of quarantined susceptible individuals) induces the phenomenon of backward bifurcation when the associated reproduction threshold is less than unity (thereby making effective disease control difficult).
The numerus clausus is made effective in controlling the intake of medical students through either a competitive entrance exam or, in the case of France, in controlling the number of students entering the second year of study in medical schools, as in the French Community of Belgium.
