An inductively coupled plasma torch (ICPT) system was used to synthesize nanosilica particles starting both from glass powders from fluorescent lamps and tetraethyl orthosilicate (TEOS) as precursors. The effect of the curtain gas on nanoparticles size, morphology and composition was studied by the use of BET, SEM and EDS analysis.

In this paper, we propose a fuzzy-servoing controller method for automatic welding. The proposed method uses a vision based arc tracking to find the initial points of the weld seam and to track them without a prior knowledge. Due to a serious melt down in the weld pool during the welding process, the method requires to control the welding torch in two directions, up-down and left-right directio...

In the Philosophy and Engineering community, there is general agreement that interaction between the two fields can be mutually beneficial. However, there are distinctive ways in which engineering can play a crucial role in assisting the particular case of philosophy of mind, especially concerning our understanding of conscious experience and perception. The reciprocal design/use cycle of certa...

C JHP – Vol. 69, No. 2 – March–April 2016 JCPH – Vol. 69, no 2 – mars–avril 2016 distinctive features such as the Point Counterpoint section, the recently completed Research Primer series, and the recently initiated International Perspectives on Pharmacy Practice series. In 2014, the CJHP celebrated its 45th anni versary of continuous publication, although its publication history extends back t...

The multicomponent alloys with nearly equal concentration of components, also known as high entropy (HEAs), were first proposed 22 years ago. HEAs quickly became very important in materials science due to their unique properties. Nowadays, the are frequently used energy conversion and storage applications. can consist five, six or more components. Plasma cladding permits coating large surfaces ...

PURPOSE The present study was intended to evaluate the effect of soldering techniques with infrared ray and gas torch under different gap distances (0.3 mm and 0.5 mm) on the tensile strength and surface porosity formation in Ni-Cr base metal alloy. MATERIALS AND METHODS Thirty five dumbbell shaped Ni-Cr alloy specimens were prepared and assigned to 5 groups according to the soldering method ...

Intrauterine infections are important causes of childhood blindness in both developed and developing countries. Chorioretinal scars are the most characteristic eye manifestation of a congenital or prenatal infection. The various ocular manifestations of congenital infections, summarized by the mnemonic TORCH, and recent additions to the "other" category (lymphocytic choriomeningitis virus and W...

So there I was - 3am on a cold December morning walking around the pontoons of an oil rig, seawater swirling over my boots, torch in one hand, lead in the other and on the end of the lead.., a diver. How did this happen to a nurse and why wasn't I in a nice warm hospital?

Mechanical and ablation properties of the 2D C/C-ZrB2-ZrC-SiC composites with a fiber volume fraction of 17.6%, fabricated by infiltration and co-pyrolysis of blended polymeric precursors, were studied in this Part II. Flexural strength and fracture toughness of the composites were found to be influenced strongly by the thickness of the deposited pyrolytic carbon interphase, a composite with th...

INTRODUCTION The frequency of fetopathogenic viruses and Toxoplasma gondii infections in the TORCH group (Toxoplasma gondii, rubella virus, cytomegalovirus (CMV), herpes simplex virus) together with Parvovirus B19 (B19) in pregnant women with bad obstetric history (BOH) and/or concurrent pregnancy complications was investigated. METHODOLOGY Sixty women (20-35 years) with BOH and/or antecedent...
