The development of light-controlled electronic devices requires new possibilities of optical control via tuning of laser input parameters. Here, Fe3O4 superparamagnetic nanoparticles (SNPs) were doped with dye, and the controllability of parameters of a r... see more

In this report we demonstrate the transformation of the photon density curves in operation of a three modes random laser when the gain coefficients of modes depending on time.Supposing gain coefficients having Gaussian profile and using Matlab language, w... see more

The ZnO powder which consists of monodisperse colloidal spheres with average diameter of 100-300 nm was synthesized by hydrolysis of Zinc acetate dehydrate. The random lasing around 380 nm was produced from a layer of the ZnO powder painted on a glass sub... see more

Objectives: Finding predictable approaches for root surface biomodification is an important challenge in the treatment of gingival recession. This study sought to assess the root coverage percentage by subepithelial connective tissue graft (SCTG) followin... see more

Este artigo propõe uma metodologia para a extração automática de contornos detelhados de edifícios a partir de um MDE (Modelo Digital de Elevação), gerado apartir da regularização de uma malha irregular de dados laser preexistentes. Ametodologia baseia-se... see more

BACKGROUND: Restoring masticatory function and replacing missing teeth with minimal pain and discomfort are the most important issues for the patient and clinician. Nowadays dental implants became the most popular line of treatment to replace missing teet... see more

Objective: To compare the mean operative time (MOT) in patients undergoing Ho: YAG laser lithotripsy (LL) and pneumatic lithotripsy (PL) for ureteric stones.Methods: This randomized study was conducted at Armed Forces Institute of Urology (AFIU) Rawalpind... see more
