A 63-year-old white man with anisometropic hyperopia presented with cataract in both eyes. He had uneventful temporal limbal phacoemulsification with intracapsular placement of a multifocal 3-piece silicone intraocular lens (IOL) in his right eye (model SA-40N, Allergan, Inc.). One week later, 2 intracapsular 3-piece silicone IOLs (1 monofocal backward, Allergan model SI-40NB; 1 multifocal in f...

INTRODUCTION The compressive loading on the cervical spine results the activation of the neck muscles to counterbalance their impact on the posture of the joint. Wearing a helmet in many sports or military and work activities increases the compressive loading. The compressive load is estimated to range from 120 to 1200N [1]. In this current study and based on our finite element model, we aim to...

Due to the superior mechanical and thermal properties of nanomaterials like multi-walled carbon nanotubes, aluminum alloys containing them play a significant role in aerospace automotive industries. By incorporating nanotubes by weight percentage (0, 0.25, 0.50, 0.75) Aluminum silicon alloy. proper dispersion is done using ball milling equipment get bonding between Aluminium alloy with MWCNT th...

PURPOSE To evaluate the outcomes of phacoemulsification with binocular implantation of SA-40N multifocal intraocular lens at the "Hospital de Olhos de Minas Gerais". METHODS The charts of 58 patients (116 eyes) who were submitted to phacoemulsification with binocular implantation of SA-40N multifocal intraocular lens were retrospectively analyzed. RESULTS The mean preoperative spherical equ...

In this study, four different alloys of steel blocks with a thickness 15mm were manufactured in order to develop an alternative plates used wear exposed areas construction machines, trucks, and asphalt production plants. To further increase the resistance blocks, their was reduced 10mm by hot-rolling method. Wear specimens obtained from rolled blocks. These abraded at 20N, 40N, 60N loads recipr...

The boundary-value problem is discretized on several grids (or finite-element spaces) of widely different mesh sizes. Interactions between these levels enable us (i) to solve the possibly nonlinear system of n discrete equations in 0(n) operations (40n additions and shifts for Poisson problems); (ii) to conveniently adapt the discretization (the local mesh size, local order of approximation, et...

Bu çalışmada; farklı oranlarda (3-15-30 ppm) bor ilavesi ile üretilen 1040 kalite ıslah çeliklerinin korozif aşınma davranışları incelenmiştir. Yapılan çalışma ortamda aşınmaya maruz kalan çeliklerin dayanımının arttırılması ve bu şartlar altında ilave edilebilecek maksimum miktarının belirlenmesi amaçlanmıştır. bağlamda, edilen ticari çelikler, davranışlarının amacıyla %3,5 sodyum klorür (NaCl...

An objective of the study is to get new biogeographic information on the modern polycystine radiolarians from the high-latitude North Atlantic. The quantitative radiolarian dataset was compiled from publications and own micropaleontological counts from samples of the bottom surface sediments of the North Atlantic north of 40N and Nordic Seas. Standard statistical treatment of micropaleontologic...
