this study was conducted to investigation and determine of cadmium (cd) concentration in the liver of platycephalus indicus (flathead) in minab, qeshm island and khamir port (persian gulf). moreover, the effect of season (winter and summer) and sex (male and female) on cd concentration in flathead were investigated. cd concentration sampling was done in two station (minab, qeshm island and kham...

promise de port fort is an useful legal basic for justification many civil and commercial transactions. such as bank guaranties, insurance and guaranty of things it divides two legal relations, relation between parties if third party not ratify and relation with third party if she or he ratify that promise. unlike its appearance, it, is not violation the principle of relativity of contracts. be...

Abstract Background Peripheral blood vessels, due to availability are used for many years in cancer patients, however in patients with potentially harmful drugs to skin (vesicant drugs) or difficult accessibility to vessels, the use of implantable port (totally implantable venous access port-TIVAP)devices with central vascular access are important.  ...

Implantable ports are used for intravenous infusion therapy and play an important role in management of oncology patients. These ports are best suited for patients requiring long-term therapy (>4 weeks). Implanted ports provide reliable venous access protect peripheral access increase patients’ comfort through reducing repeated and difficult vein punctures allow for safe and comfortable admi...

In this paper, we present a switch based on coupling and resonance in thegraphene plate and rings operating at 10 THz. This structure consists of several layers ofHexagonal Boron Nitride (hBN), SiO2 and P+Si, such that graphene plates and rings areinside the hBN layer. The terahertz wave is incident from the upper part of the switchand Surface Plasmons (SPs) are excited ...

In this paper, a new multilayer six-port circuit using ultra-wideband directional coupler is presented and implemented. The use of the multilayer technology allows having a compact circuit and a very large bandwidth. To validate this concept, a six-port prototype was fabricated and measured. Simulation and measurement results show the proposed six-port circuit can easily operate over an ultra-w...

It is important for general practitioners to recognize cutaneous port-wine stains as these could signify important association with Sturge Weber syndrome, where neurological and ocular complications are likely. As importantly, advances in technology in the past two decades have made laser the standard of care for the management of port-wine stains. Port-wine stains are venous ectasias that are ...

Purpose. Port-site metastasis has been a concern with the common use of laparoscopy in urologic oncology. We conducted this study to provide a review of port-site metastases reported after the laparoscopy in managing urologic malignancies, possible contributing factors and preventative measures. Materials and Methods. An electronic search of MEDLINE using the combined MESH key words "port-site ...

In opinion of substructure cascade, multimode feed network is composed of impedance transforming substructure and isolating substructure. Starting from the characteristic of the substructure in multimode feed network, a method of measurement for its three-port scatter parameters of substructure is presented, based on the applying of the available two-port vector network analyzer (VNA), consider...

BACKGROUND The use of advanced laparoscopy remains controversial in the field of surgical oncology because the potential for port-site recurrence may violate sound oncologic principles. Two mechanisms are theorized to be the cause of port-site recurrences: first, indirect contamination caused by pneumoperitoneum, aerosolization, or intraperitoneal spread, and second, direct contamination by phy...
