Different designs have been presented to achieve high concentration and uniformity for the concentrated photovoltaic (CPV) system. Most of the designs have issues of low efficiency in terms of irradiance uniformity. To this end, we present a design methodology to increase irradiance uniformity over solar cell. The system consists of an eight-fold Fresnel lens as a primary optical element (POE) ...

Optical design and fabrication techniques are crucial for making optical elements. From conventional lenses to diffractive optical elements and to recent metasurfaces, various types of optical elements have been proposed to manipulate light where optical materials are fabricated into desired structures. Here, we propose a scattering optical element (SOE) that exploits multiple light scattering ...

background: formation of secondary structure such as dna hairpins or loops may influence molecular genetics methods and pcr based approaches necessary for genetic engineering, in addition to gene regulation. materials and methods: a polymerase chain reaction with splice overlap extension (soe-pcr) was used to create fully synthetic 1f5 chimeric anti-cd20 heavy- and light-chain genes. the chimer...

Abstract The majority of supervisor organizational embodiment (SOE) research has focused on its role as an important boundary condition in the context leadership and management studies. In a multi-source field study, we seek to extend this stream by examining antecedent outcome SOE. Specifically, leverage social cognitive theory develop test trickle-down model across three levels (i.e., upper-l...

In this Letter, we propose an intracorporeal illumination system for providing uniform and wide-field illumination during minimally invasive surgery. The illumination system is comprised of an Alexis wound retractor, a set of LEDs, and secondary optical elements (SOEs). The SOE was composed of a Fresnel lens and a total internal reflection lens, which was designed to improve the optical perform...

The study explores the relationship between gender diversity board (GDB) and earnings management (EM) with state-ownership (SOE) firm growth as moderating factors. Based on data of 404 Vietnamese listed firms in 2015–2019, feasible generalized least squares (FGLS) method further tests are employed to confirm results. Furthermore, this research compares results multiple regression analysis (MRA)...

in the present study we aimed to evaluate the effects of methanolic extracts of the bulbs of garlic (allium sativum l., alliaceae) and persian shallot (allium ascalonicum l., alliaceae ) and leaves of sage (salvia officinalis l., lamiaceae ), ase, aae and soe respectively, on the antioxidant enzymes such as superoxide dismutase (sod), glutathione peroxidase (gpx) and catalase (cat) activities an...
