In spite of being statistically significant in some parts, the amounts of refractive and corneal topographic changes were not clinically remarkable. Therefore, it does not seem necessary to perform cycloplegic refraction early after horizontal rectus muscle recession; however, a precise refraction in all cases of strabismus should not be deferred later than 3 months.

Abstract. In the current research, Rhodium (III) Oxide (Rh 2 O 3 ) nanoparticles were produced in various sizes using ultrasonic waves and by adding various concentrations of linoleic acid as capping agent. Using X-Ray Diffraction (XRD) methods, phytochemical and structural characteristics of the produced samples were studied and the mean particle size was calculated by Debye -Scherer equation. The phytochemical characteristics of the produced nanoparticles were studied by Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy (ATR-FTIR). The surface morphology of these structures shows that the Rhodium (III) Oxide (Rh 2 O 3 ) nanoparticles are formed in a spherical shape.

The modeling and control design of a dragonfly-like flapping wing micro aerial vehicle (FWMAV) are studied in this paper. The aerodynamic force model of flapping wings is presented first, which is obtained by the local air velocity of the wing and local attack angle of the wing, unlike some existing works. Then, the complete mathematic model of FWMAV is developed by combining the aerodynamic force model and a kinematic model in which the micro aerial vehicle is regarded as a 6 degree-of-freedom rigid body. To mimic real dragonflies, the tail of the FWMAV swings only, unlike fixed-wing aircrafts that possess conventional control surfaces in tail. This yields a control difficulty due to the loss of the maneuverability in tail. To design an appropriate control mechanism, the complete FWMAV model, which is highly nonlinear, is rewritten in a companion form. The controller is designed to iteratively solve for a desired control signal profile by means of a dual-loop nonlinear dynamic inversion with Newton-Raphson solution. Numerical simulation results show that the effectiveness and convergence performance of the nonlinear controller are obtained. Modeling and Control of a Dragonfly-like Micro Aerial Vehicle

The work is an evolution of research already begin and in development. Therefore, we can observe a part that has already been commented that presents the whole development of the research from its beginning. A small review of the main compounds employed some of their known physicochemical and biological properties and the ab initio methods used. Preliminary bibliographic studies did not reveal any works with characteristics studied here.With this arrangement of atoms and employees with such goals. So, the absence of a referential of the theme. The initial idea was to construct a molecule that was stable, using the chemical elements Lithium, Beryllium, alkaline and alkaline earth metals, respectively, as electropositive and electronegative elements -Selenium and Silicon, semimetal and nonmetal, respectively. This molecule would be the basis of the structure of a crystal, whose structure was constructed only with the selected elements. The elements Li, Be, Se and Si were chosen due to their physicochemical properties, and their use in several areas of technology [1][2][3][4]. To construct such a molecule, which was called a seed molecule, quantum chemistry was used by ab initio methods [5,6,7]. The equipment used was a cluster of the Biophysics laboratory built specifically for this task.

Due to the extensive usage of anti-cancers, the spread of multidrug resistant DNA of cancer cells is one of the most worrying threats to public health. In this editorial, the susceptibility of DNA of cancer cells to inactivation by a novel treatment, which involves applying appropriate UV irradiation at presence of Cadmium Oxide (CdO) nanoparticles on DNA of cancer cells, as a promising method for medical, clinical, biological, pharmaceutical, biochemical and photodynamic applications were analyzed.

Background: Parents of children with phenylketonuria are at risk of reduced quality of life. Aims: This study determined the quality of life of parents of children with phenylketonuria in Tehran Province. Methods: The study was conducted in 2015 and included parents of children with phenylketonuria referred to three government children's hospitals in Tehran Province that provide phenylketonuria services. Data were collected using the Farsi version of the World Health Organization Quality of Life-Bref questionnaire. Analysis of variance, t-test, Pearson correlation coefficient and multiple linear regression were used to assess the relationship between quality of life domains and sociodemographic characteristics of the parent and child. Results: The study included 240 parents; 55% were mothers. Quality of life of parents in psychological, social relationships and environment domains was low. Significant relationships were found between: physical domain and age of child at phenylketonuria diagnosis (P = 0.044); psychological domain and parent's age (P = 0.019), child's age (P = 0.007) and parent's education (P = 0.015); social relationships domain and parent's age (P = 0.003), and education (P = 0.002), household income (P = 0.025) and child's age (P = 0.004; and environmental domain and residence (P = 0.034), parent's education (P = 0.007), household income (P = 0.002) and child's age (P = 0.049). In the multivariable analysis, parent's age and education, child's age, and household income were significantly associated with parent's quality of life. Conclusion: Given the low levels of quality of life in the parents, education and more financial support are recommended.
