in this paper we modified a simple two-dimensional photonic crystal waveguide by creating micro cavity resonators in order to increase the output light emission which can be applicable to photonic integrated circuits. The micro cavity resonators are constructed by removing two tubes close to the waveguide output. Coupling emitted light from waveguide with those micro cavities, results increasin...

The fatigue cracks are observed in asphalt surfaces much more than ruts. This paper deals with the influence of carbon nano-tube on the fatigue life of asphalt mixtures. These samples are made up of the slabs cut by the asphalt cutting saw. Fatigue beams contain 0, 0.3, 0.6, 0.9, 1.2, and 1.5 percent of Carbon Nano-tube. The fatigue experiment was conducted using a 4-point semi-sinusoidal loadi...

Scaffolds play a pivotal role in the tissue engineering paradigm by providing temporary structural support, guiding cells to grow, assisting the transport of essential nutrients and waste products, and facilitating the formation of functional tissues and organs. Single-walled carbon nanotubes (SWNTs), especially ultra-short SWNTs (US-tubes), have proven useful for reinforcing synthetic polymeri...

composites with micro- and nano-metal fillers has attracted the attention of researchers for radiation shielding applications. Lead toxicity and heaviness have oriented extensive research toward the use of non-lead composite shields. The present study aimed to systematically review the efficiency of the composite shields of various micro- and nano-sized materials as composite shields have been ...

AIMS This study describes a prospective consecutive case series of the initial six eyes of five patients undergoing implantation of the trabecular bypass tube shunt. METHODS A prospective consecutive case series. The initial six eyes of five patients with uncontrolled open angle glaucoma who had never previously undergone ocular surgery. Implantation of the trabecular bypass tube shunt measur...

We investigated performance of ultrafast (30 fs –200 fs) laser-based x-ray source as an alternative to a microfocal x-ray tube used in micro-CT systems. A number of solid targets including Ge, Mo, Rh, Ag, Sn, Ba, La, Nd with matching filters was used. We optimized conditions for x-rays generation, measured x-ray spectra and obtained images of small animals using various characteristic x-ray lin...

Mass flow inequality in the initial stage of tube processing can lead to eccentricity and micro- nano-structural changes that affect residual stress texture development. In this study, macro- micro-texture development copper tubes drawn with a tilted die was investigated using three methods: synchrotron, neutron diffraction, electron backscatter positions maximum minimum wall thickness tubes. U...

The Delves micro-scale technique for blood lead analysis is an accurate method for screening capillary blood specimens, obtained by fingerstick, for lead intoxication. Results are affected by the age of cup, loop, and hollow-cathode tube and by the spatial relationship between optical tube and cup. Because the glass in many commercially available capillary tubes (used in specimen collection) ...

INTRODUCTION Erythrocyte sedimentation rate (ESR) remains as one of the most reliable tests in clinical practices. Yet its use is time consuming and requires a large blood sample. The aim of this study was assessing a faster and reliable method of ESR estimation. METHODS An ESR estimation method was described and performed on 108 patients using capillary tube (micro ESR) and capillary periphe...

This paper presents the design optimization of diaphragms for a micro-shock tube-based drug delivery device. The function of the diaphragm is to impart the required velocity and direction to the loosely held drug particles on the diaphragm through van der Waals interaction. The finite element model-based studies involved diaphragms made up of copper, brass and aluminium. The study of the influe...
