In Brazil, insecticide resistance in Stegomyia aegypti (= Aedes aegypti) (Diptera: Culicidae) populations to pyrethroids and to the organophosphate (OP) temephos is disseminated. Currently, insect growth regulators (IGRs) and the OP malathion are employed against larvae and adults, respectively. Bioassays with mosquitoes from two northeast municipalities, Crato and Aracaju, revealed, in both populations,...
An improved periodic defected ground structure (DGS) is investigated for low-pass filter (LPF) applications. The realization in microstrip configuration consists in making the equivalence between the geometry of a DGS structure and a parallel LC resonator circuit. Initially, one filter is designed using identical DGS, equally spaced. Varying empirically the dimensions of the DGS, we obtain an improvement...
Background Laparoscopy is a technique used in various surgical procedures. Few studies in the literature compare stress between laparoscopic and open surgery used for esophagogastric surgical procedures. Pulmonary function is known to be significantly affected in open surgeries, increasing postoperative morbidity and mortality. The current study aimed to assess pulmonary function in patients before...
