Background: Implantable Phakic Contact Lenses have been developed as a cost-effective alternative to Visian Collamer lenses for refractive correction. Aim of the work: evaluate central vault implantable phakic contact lens (IPCL) and its correlation horizontal white (WTW) corneal diameter using anterior segment optical coherence tomography. Patients Methods: 30 eyes that match inclusion criteri...

In this paper‎, ‎an efficient dropping criterion has been used to compute the IUL factorization obtained from Backward Factored APproximate INVerse (BFAPINV) and ILU factorization obtained from Forward Factored APproximate INVerse (FFAPINV) algorithms‎. ‎We use different drop tolerance parameters to compute the preconditioners‎. ‎To study the effect of such a dropping on the quality of the ILU ...

The Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) model incorporated fuel economy and electricity use of alternative fuel/vehicle systems simulated by the Powertrain System Analysis Toolkit (PSAT) to conduct a well-to-wheels (WTW) analysis of energy use and greenhouse gas (GHG) emissions of plug-in hybrid electric vehicles (PHEVs). Based on PSAT simulations of ...

PURPOSE To assess the efficacy of high-frequency ultrasound biomicroscopy (UBM) in improving the accuracy of phakic intraocular lens (pIOL) sizing by increasing the incidence of acceptable postoperative vault. SETTING Multiple private practices, United States. DESIGN Evaluation of diagnostic test or technology. METHODS This prospective multicenter clinical study evaluated eyes having pIOL...

Cities consume most of the energy used worldwide and are largest emitters greenhouse gases (GHGs) that cause global warming, mainly from road transport sector. In megacities, light vehicle fleet is responsible for emissions in Among this fleet, commercial vehicles (CVs), which have grown to support instant delivery services demand, also traffic congestion. Due urgency reduce impacts, emission m...

Polycyclic aromatic hydrocarbons (PAHs) were probed in the leaves of Piper guineense obtained from Orieugba and Isigate markets within Umuahia metropolis North Local Government Area Abia State. Prior to drying, milling extraction procedures, P. each these was divided into three portions. The first portion not washed (UW), second with ordinary tap water (WTW) while third about 0.17 mol dm-3 NaCl...

the polynomial interpolation in one dimensional space r is an important method to approximate the functions. the lagrange and newton methods are two well known types of interpolations. in this work, we describe the semi inherited interpolation for approximating the values of a function. in this case, the interpolation matrix has the semi inherited lu factorization.

Several countries have set ambitious targets for the transport sector that mandate a gradual increase in advanced biofuel content coming years. The current work addresses this transition and indicates two promising gasoline bio-blendstocks: Anisole isobutanol. whole value chains of these bio-components were considered, focusing on end-use performance, but also analyzing feedstock its conversion...

The International Maritime Organization (IMO) has set decarbonisation goals for the shipping industry. As a result, shipowners and operators are preparing to use low- or zero-carbon alternative fuels. greenhouse gas (GHG) emission performances fundamental choosing suitable marine However, current regulations adopt tank-to-wake (TTW) assessment methods that could misrepresent total climate impac...
