Objective(s): Response surface methodology (RSM) by central composite design (CCD) was applied to statistically optimize the preparation of Rutin-Quercetin (Ru-Qr) dual drug loaded human hair keratin nanoparticles as well as evaluate the characteristics. Materials and Methods: The effects of three independent parameters, namely, temperature (X1:10-40 C), surfactant (X2: SDS (1), SLS (2), Tween-...

  Background: The sale of food by street vendors is an activity of economic, sanitary, and nutritional importance, but these foods can pose a high risk to the health of consumers in inadequate conditions of preparation and storage. The aim of this study was to investigate the preparation conditions and the hygienic-sanitary quality of food sold by street vendors in the vicinity of four campuse...

Environmental planning and management can have positive effects on development of some land uses including industrial areas that have a major effect on economic, social and environmental conditions. Considering the most important problems associated with modeling, the fundamental methods and functions of site-selection laid inside the geographical information system are not accounted for the mu...

Recorded ground motions in near fault region have completely distinct nature from others that recorded in far field of the fault. Near source outcomes cause much of the seismic energy to appear in a single large and long period pulse at the beginning of the velocity record. Assaluyeh complex is located near the reverse Assaluyeh fault that is a segment of Mountain Front Fault. This complex cont...

The researchers express their gratitude to the Association of American Railroads, Dr. Duane Otter, principal engineer at its Transportation Technology Center, Inc., and Mr. Bill Riehl, director of structures for Rail America for extensive assistance in seeking interested railroad owners with potential sites for field investigation of the shear spiking technique. Mr. Tomasz Gawronski, director o...

OBJECTIVE Pancreatic transplantation has been relatively uncommon until the last 2 decades, but is now an accepted therapeutic intervention for type I diabetes. Core biopsies of pancreas transplants are frequently performed to rule out rejection, which is a leading cause of graft failure. Often, it is difficult to localize the graft for biopsy by imaging. Our objective was to determine whether ...

STUDY DESIGN A prospective, randomized, controlled study. PURPOSE The objective of this study was to evaluate the effectiveness of two techniques of skin preparation with povidone-iodine. OVERVIEW OF LITERATURE Preoperative skin preparation is important for preventing surgical site infection by reducing the bacteria in the surgical area. Povidone-iodine is a commonly used agent for preopera...

The excessive temperature fluctuations during dental implant site preparation may affect the process of bone-implant osseointegration. In the presented studies, we aimed to assess the quality of cooling during the use of 3 different dental implant systems (BEGO®, NEO BIOTECH®, and BIOMET 3i®). The swine rib was chosen as a study model. The preparation of dental implant site was performed with t...

Land managers throughout the Southeast are interested in restoring the longleaf pine (Pinus palustris Mill.) ecosystem, due in part to its value as habitat for the endangered red-cockaded woodpecker (Picoides borealis). In 2003, we established a study at Camp Lejeune, NC, to determine the effects of common site preparation treatments (mounding, bedding, herbicide, and chopping) on longleaf pine...

PURPOSE Various parameters can influence temperature rise and detection during implant site preparation. The aim of this study is to investigate local temperature values in cortical and corticocancellous bovine bone during early stages of piezoelectric implant site preparation. MATERIALS AND METHODS 20 osteotomies were performed using a diamond tip (IM1s, Mectron Medical Technology, Carasco, ...
