[WT5”HZ]Results [WT5”BZ]The positive rate of questionaire was 58.90%, and so 41 10% was not carried out IHA after questionaire screen and it could save 34 04% examination cost in comparison with mass IHA examination. The effect of control was similar between screened-examination group and mass-examination group. Cost-effectiveness in screened-examination group were lower than those in mass-examination group.
Conclusion The result of malaria surveillance in southern Fujian shows that multiplex PCR assay is sensitive,specific and prompt,and can be used for malaria molecular epidemicological investigation,assessment of effect of control and detemination of Plasmodium species.
Flutter control effect and mechanism of central-slotting for long-span bridges
The control effect of central-slotting depends on the aerodynamic configuration of the original girder section and the corresponding central-slotting width.
The control channel is divided into two channels (fast and slow) for enhancing the speed of response at a significant range of the control effect.
Simulation results indicated that the proposed controller exhibits satisfying control effect.
The activities of enzymes responsible for lignification in pepper, pre-inoculation with arbuscular mycorrhizal (AM) fungus ofGlomus intraradices and/or infection with pathogenic strain ofPhytophthora capsici, and the biological control effect ofG.
These conditions admit considerable variations for the estimates of the control effectiveness matrix in the neighborhood of their exact values, thereby corroborating the possibility of using the adaptation scheme for a wide class of objects.
Numerical results show that the proposed control strategy has high control effectiveness and efficiency.
The results illustrate that the structure presented in the paper has excellent dynamic properties and satisfactory control effectiveness.
It accounts for changing levels of project activities and includes parameters that represent control effectiveness and project management effectiveness.
Control effectiveness was above 95%; the larvae density decreased from 52.5 to 0.94 per 50cm sample twig and direct economical benefit was 3,935,420 Chinese yuan.
