we have designed a new type of optical channel drop filter (cdf) based on two dimensionaltriangular lattice photonic crystals. cdf operation is based on coupling to the photonic crystalwaveguide. the proposed structure is optimized to work as a cdf for obtaining the cdfcharacteristics and band structure of the filter the finite difference time domain (fdtd) method andplane wave expansion (pwe) ...

In the present paper a novel structure for optical channel drop filter (CDF) based on photonic crystal ring resonator with circular core has been proposed. In order to design the proposed CDF, the plan wave expansion (PWE) method is applied for calculation of band structure and photonic band gap while the transmission characteristics of proposed CDF have been calculated using the finite differe...

Zinc is essential for many cellular processes. To use Caenorhabditis elegans to study zinc metabolism, we developed culture conditions allowing full control of dietary zinc and methods to measure zinc content of animals. Dietary zinc dramatically affected growth and zinc content; wild-type worms survived from 7 microm to 1.3 mm dietary zinc, and zinc content varied 27-fold. We investigated cdf-...

This study examined the impact of hepatic transport protein modulation on the hepatobiliary disposition of a nonmetabolized probe substrate, 5- (and 6)-carboxy-2',7'dichlorofluorescein (CDF) in rat isolated perfused livers (IPLs). In vivo treatment with modulators (100 and 200 mg/kg/day clofibric acid, 80 mg/kg/day phenobarbital, and 25 mg/kg/day dexamethasone) was used to alter the expression ...

Hepatic disposition of 5 (and 6)-carboxy-2',7'-dichlorofluorescein (CDF) and its diacetate promoiety (CDFDA) was studied in isolated perfused rat livers. Livers from Wistar wild-type and multidrug resistance-associated protein (Mrp)2-deficient (TR(-)) rats were perfused with CDF in the presence or absence of probenecid. Probenecid decreased the recovery of CDF in bile approximately 4-fold in wi...

Cadmium fluoride (CdF) is commonly used as an insulator for ulta high speed mass telecommunications equipment, and there is a considerable risk that industrial workers will inhale CdF particles. Despite the possibility that acute exposure can cause harmful systemic effects, there are no studies to date that address the health consequences of acute CdF exposure. This study therefore aimed to det...

The current study was aimed to develop a targeted dendrimer formulation of 3, 4-difluorobenzylidene curcumin (CDF) and evaluate its potential in CD44 targeted therapy for pancreatic cancer. Using amine terminated fourth generation poly(amidoamine) (PAMAM) dendrimer nanocarrier and hyaluronic acid (HA) as a targeting ligand, we engineered a CD44-targeted PAMAM dendrimer (HA-PAMAM) formulation of...

The Kenyan Constituency Development Fund (CDF) aims to alleviate poverty by allocating resources to constituencies which MPs and residents decide how to spend. In this paper we assess whether MPs’ re-election chances were affected by their management of the CDF. For this purpose we analyse the type of projects implemented by the CDF and residents’ opinion about their MP and the CDF. We find tha...

CDF aimed at ensuring development in each constituency in Kenya. Despite having CDF, allocation Samburu West Constituency has not registered significant change in education and health services. The study aimed at assessing the extent to which CDF Results of the current study revealed that CDF has helped in improving health and education services at community level through, developing new dispen...
