Based on the optical deflection method, the resonant characteristics of a microcantilever under various pressure have been observed at room temperature to understand the pressure-dependent dissipation effect. Especially, the quality factor of the cantilever has been measured for up to fourth harmonic mode of cantilever resonance as a function of pressure between 0.1 and 1000 Torr. By considerin...
This review assesses the range and quality of the evidence base on the cost-effectiveness of malaria prevention and treatment in sub-Saharan Africa. Fourteen studies are reviewed, covering insecticide-treated nets, residual spraying, chemoprophylaxis for children, chemoprophylaxis or intermittent treatment for pregnant women, a hypothetical vaccine, and changing the first line drug for treatmen...
Complete sets of elastic, piezoelectric, and dielectric constants of 0.72Pb(Mg(1∕3)Nb(2∕3))O(3)-0.28PbTiO(3) single crystal poled along [111](c) (single domain) as well as non-polar axes [001](c) and [011](c) (multidomain) have been measured under natural conditions. These data allowed us to evaluate accurately the extrinsic contributions to the superior piezoelectric properties. Very large ext...
The concept of the quality-adjusted life year (QALY) provides a simple technical tool for summarising the impact a medical condition has on someone's life and the impact a health care intervention can have on that medical condition. In the former case, QALYs (and related concepts, such as disability-adjusted life years, DALYs) have been useful in producing summary statistics on the burden of di...

In this paper a Frequency Selective Surface (FSS) as a UWB electromagnetic shield is introduced. The proposed FSS comprises a quasi-J.C-Jerusalem Cross- and a copper ring, which are located at both sides of a FR4 substrate and can represent a S.E -Shielding Effectiveness- better than 20dB in 90% bandwidth of Ultra Wide Band frequency. This structure is compact and thin. Each cell comprises J.C ...
background: chronic obstructive pulmonary disease (copd) is a chronic respiratory disease, which reduces the lung function and causes respiratory symptoms over time, and it is primarily associated with shortness of breath, cough and sputum production. roflumilast, which is a long-acting selective inhibitor, reduces the anti-inflammatory effect of the main symptoms of copd. the aim of this study...
agricultural training centres (atcs) promote crop and livestock development by providing extension information to farmers and serving as models of improved crop and livestock husbandry practices. although potato farmers in nyandarua county were trained on potato production technologies, their average yield was ≤16 tonnes per hectare compared to the national potential of 30 tonnes. this study th...
abstract nowadays, bypassing agents such as recombinant activated factor vii (rfviia) and activated prothrombin complex concentrates (apcc) are used to treat bleeding episodes in the hemophilia patients with inhibitors. aryoseven® is an iranian biogeneric rfviia with homogeneity of efficacy and the nature to novoseven in a comparative trial. the current clinical trial aimed to evaluate the cost...
