Specially designed metal-dielectric composites can have a negative refractive index in the optical range. Specifically, it is shown that arrays of single and paired nanorods can provide such negative refraction. For pairs of metal rods, a negative refractive index has been observed at 1.5 μm. The inverted structure of paired voids in metal films may also exhibit a negative refractive index. A s...
BACKGROUND The level of proliferation activity is a strong prognostic or predictive indicator in breast cancer, but its optimal measurement is still in debate, necessitating new proliferation markers. In the present study, the prognostic significance of the CKAP2-positive cell count (CPCC), a new proliferation marker, was evaluated, and the results were compared with those for the mitotic activ...
Non-sagittal occlusal discrepancies such as posterior cross-bite and anterior openbite are common types of malocclusion, but studies on masticatory function related to those malocclusions have been scarce. The aim of this study was to quantify the masticatory performance in patients with non-sagittal discrepancies compared to those with normal occlusion, using both objective and subjective meas...
The present research was designed to study and compare the biochemical parameters in Labeo rohita due to exceptional nutritional value of this fish as a protein source in developing countries. The protein and heavy metal (Zn, Cu, Ni) activities were determined spectrophotometrically. The proximate analysis of L. rohita collected from different localities of Pakistan revealed that the protein (1...
background: soil and sediment serve as major reservoir for contaminants as they possess ability to bind various chemicals together. in this study the concentrations of heavy metals cd, cr and cu were analyzed in surface sediments of agh gel wetland in west of iran. methods: the sediment samples were taken from 10 stations. the samples were subjected to bulk digestion and chemical partitioning a...
Constant use of treated wastewater (TWW) for irrigation over long periods may cause buildup of heavy metals up to toxic levels for plants, animals, and entails environmental hazards in different aspects. The aim of this study was to assess the effect of using a deep emitter installation on lowering the potential heavy metal accumulation in soil and wheat grain, and health risk under drip irriga...
background facultative marine fungi could potentially be arsenic tolerant and may be able to remove this highly poisonous metal from the environment. objectives the objective of this work was to explore the degree of tolerance and removal efficiency of two facultative marine fungi. materials and methods facultative marine fungi aspergillus flavus and rhizopus spp. were exposed to 25 mg/l and 50...
