A novel dual-band microstrip antenna for an internal notebook antenna for WLAN operation is presented. The antenna has a simple structure consisting of a spiral strip. The proposed antenna has a low profile and can easily be fed by using a 50 Ω microstrip line. It is believed that the size of the antenna is about the smallest among the existing internal laptop antennas for 2.4/5.8GHz WLAN opera...

A case of three pancreaticoduodenal artery (PDA) aneurysms associated with coeliac artery occlusion and a concomitant splenic arterial aneurysm is described. Surgical treatment was used because it was anticipated that the hepatic blood supply would be obstructed completely if percutaneous transluminal embolization for three PDA aneurysms were performed. Splenectomy in continuity with the spleni...

Introduction: Coronary artery disease caused by atherosclerosis is a significant health problem worldwide. In the United States alone, over 370,000 people die from the disease each year [1]. The current gold standard for the treatment of coronary artery disease is the transplantation of autologous blood vessels. However, lack of sufficient donor tissue and donor-site morbidity are major limitat...

Objective: To assess its role in stone clearance along with ESWLin patients upper ureteric stones. Method: This clinical trial was conducted from February 2018 to December 2021 at the Department of Urology, Services Hospital Lahore.. Atotal 164 (82 each group) both sexes between ages 18 and 70 years (6mm-15mm) were included this study. These randomly divided into two groups. Patients group A re...

Plafon adalah bagian dari konstruksi atap yang berpengaruh terhadap kesejukan ruang dalam. Penggunaan plafon dapat mengurangi beban panas dalam karena masuk atap, ditahan antara penutup dan saja. Bahan sangat berperan proses penghambatan pengaliran ke sehingga pendinginan sendiri (self cooling) terjadi. Masalahnya, bagaimana cara memilih bahan penggunaannya bisa efektif menahan bangunan sedangk...

the resistant* of patesa against lateral displacement (le. the stability), was studied tinder a range of conditions in vitro, at a range of knee flexion angles. muscle forces were applied in physiological directions along the separate quadriceps muscles. normal muscle actions with constant tension showed constant patellar stability up to sixty degrees knee flexion, and then a significant increa...

Abstract Introduction The CDC estimates that ∼500 000 children in the US between ages 1–5 have unsafe blood lead concentrations (> 3.5 ug/dL). Lead toxicity can affect all bodily systems and be detrimental to children's developing brains nervous systems. Since exposure does not always induce obvious immediate symptoms, screening is an essential tool public health. Recently, there was a p...

Sixteen glass ceramic blocks (IPS e.max CAD/CAM) were fabricated by a CAD/CAM machine withdimensions (6mm × 11mm x 13mm) and divided into 4 groups (n=4), according to surface treatments: (G1)Hydrofluoric acid (HF) etching silane application, (G2) Acidulated phosphate fluoride (APF) silaneapplication, (G3) Monobond Etch Prime (MEP), (G4) Tetrabutylammonium dihydrogen trifluoride (TDTF) andsilane...

In this study, we examined the morphological, chemical, and structural details of tetrahedral pyrite crystals from Jean Baptiste mine in Lavrion, Greece. Pyrite occurs three generations. Tetrahedral first generation are left- or right-handed with lowest cubic 23 symmetry. generation, there twins higher m_3 hexagonal 6 All second primarily interpenetrated into a _4m3 Some, however, continue to t...

Abstract This research aims at the X-ray attenuation effect of Graphene oxide (GO) and lead (??) Oxide (PbO) in epoxy resin (ER). First, GO was synthesized with Hummers’ method, then PbO modified finally, epoxy-based composites were prepared various fillers such as PbO/GO different weight percentages. The composite samples made thicknesses 2, 4, 6mm. investigated by scanning electron microscopy...
