Abstract Due to worldwide regulations on the application of high production volume industrial chemical bisphenol A (BPA) in various consumer products, alternative bisphenols such as F (BPF) and S (BPS) are increasingly used. To assess human exposure these chemicals, biomonitoring urinary concentrations is frequently However, short-term variability has not been evaluated thoroughly yet, which es...

The design of single- and quad-band Bandpass Filter (BPF) topology has been presented in this paper for next-generation Internet Things (IoT) devices. main is constructed using the Split Ring Resonator (SRR), separated by Anti-Parallel Coupled Line Structure (APCLS). A detailed analysis APCLS presented, which further used to construct BPF. single-band BPF consists SRR loaded with APCLS. develop...

Given the opposing responses reported for bisphenol A (BPA) in terms of induction obesogenic effects and impaired lipid metabolism, increasing use F (BPF), relatively low information available regarding bis(3-chloro-2- hydroxypropyl) ether (BADGE·2HCl) aquatic organisms, this work aims to zebrafish liver cell line (ZFL) as an alternative model characterize toxicity metabolism disruptive potenti...

For many years EDI served as the dominant protocol for e-biz over private networks. Due to the rapid spread of the Internet, several new Business-to-Business (B2B) interaction protocols have become popular, e.g., Open Buying on the Internet (OBI), RosettaNet, and Vendor-defined protocols such as Ariba’s Punchout process. We will describe these protocols, with an emphasis on their similarity and...

Laser phase noise deteriorates the high sensitivity of heterodyne optical receivers. To reduce phase noise influence, the intermediate frequency (IF) signal resulting from the coherent detection is filtered by a narrow bandpass filter (BPF). The phase noise at the input of the BPF generates an amplitude and phase noise at the output of the BPF. The joint probability density function of these no...

A novel compact ultra wideband (UWB) bandpass filter (BPF) based on composite right/left handed transmission line (CRLH TL) is reported in this paper. The proposed UWB BPF is designed and developed by coupling of two unit-cells of via-less CRLH TL, excited by asymmetrical coplanar waveguide (CPW) feed-line. The unit cell of CRLH TL is designed using series interdigital capacitor (IDC) in shunt ...

Microwave circuits embedded in a multi-layer resin PCB are demonstrated using low loss resin materials. Resin materials for microwave frequencies were compared with conventional FR-4 with respect to dielectric and conductor loss factors, which proved that losses could be reduced drastically with the low loss material and design optimizations. Baluns, switches and BPFs were designed and fabricat...

Bisphenol A (BPA) is a widely used industrial chemical that disrupts endocrine function. BPA is an endocrine disrupting chemical (EDC) that has been demonstrated to affect reproductive organ development, brain development, metabolic disease and post-natal behavior. Accordingly, Bisphenol analogs, Bisphenol F (BPF, bis (4-hydroxyphenyl) methane) and Bisphenol AF (BPAF, 4,4-hexafluoroisopropylide...

OBJECTIVE To investigate the damage to the retinal nerve fiber layer as part of the anterior visual pathway as well as an impairment of the neuronal and axonal integrity in the visual cortex as part of the posterior visual pathway with complementary neuroimaging techniques, and to correlate our results to patients' clinical symptoms concerning the visual pathway. DESIGN, SUBJECTS AND METHODS ...
