The electropolishing behaviour of 73 brass was studied by means of a rotating cylinder electrode (RCE) in a 70 vol % H3PO4 solution at 27 ◦C. Owing to the formation of a blue Cu2+-rich layer on the brass-RCE, an obvious transition peak was detected from kineticto diffusion-controlled dissolution in the anodic polarisation curve. Electropolishing was conducted at the potentials located at the tr...

OBJECTIVE To explore the biological effects of ray cartilage extract (RCE) on human breast cancer cell line MCF-7 and its mechanism. METHODS MCF-7 cells were treated with RCE of different concentrations for different durations, and then MCF-7 cell proliferation was evaluated with MTT test, cell cycle was detected with flow cytometer and the protein levels of cyclin D1 and p21 were determined ...

Resonant cavity enhanced (RCE) photodiodes (PD’s) are promising candidates for applications in optical communications and interconnects where high-speed high-efficiency photodetection is desirable. In RCE structures, the electrical properties of the photodetector remain mostly unchanged; however, the presence of the microcavity causes wavelength selectivity accompanied by a drastic increase of ...

In this paper, we investigate and systematically evaluate two machine learning algorithms for analog fault detection and isolation: (1) Restricted Coloumb Energy (RCE) Neural Network, and (2) Learning Vector Quantization (LVQ). The RCE and LVQ models excel at recognition and classiication types of problems. In order to evaluate the eecacy of the two learning algorithms, we have developed a soft...

Here, we investigated the anticancer effect of Rhus coriaria on three breast cancer cell lines. We demonstrated that Rhus coriaria ethanolic extract (RCE) inhibits the proliferation of these cell lines in a time- and concentration-dependent manner. RCE induced senescence and cell cycle arrest at G1 phase. These changes were concomitant with upregulation of p21, downregulation of cyclin D1, p27,...

AIM To investigate the effect of methanol extract of Ricinus communis seed (RCE) on male rats reproductive functions. METHODS Thirty-two male albino rats were divided into four groups. Groups 1, 2 and 3 were gavaged with 0.2 mL of 2.5% tween 80 (RCE vehicle; control) or 20 mg/(kg x d) and 40 mg/(kg x d) of RCE, respectively, for 30 days, and group 4 was also gavaged with 40 mg/(kg x d) of RCE...

We have developed the Rabbit Corneal Epithelial (RCE) Model to evaluate the in vitro eye irritation potential of chemicals including pharmaceuticals, cosmetics and their raw ingredients. In the model, a stratified culture of rabbit corneal epithelial cells is grown at the air-liquid interface on an amnion acting as a parabasal membrane. The alkaline exposure was restored each day in the presenc...

We propose and demonstrate a novel device structure of resonant cavity-enhanced photodetector (RCE-PD). The new RCE-PD structure consists of a bottom distributed Bragg reflector (DBR), a cavity with InGaAs multiple quantum wells (MQWs) for light absorption and a top mirror of sub-wavelength grating. By changing the fill factor of the 2-D grating, the effective cavity length of RCE-PDs can be va...

purpose: to study the effect of phototherapeutic keratectomy (ptk) in the treatment of various superficial corneal pathologies. methods: we performed a nonrandomized, prospective study on patients who presented with superficial corneal disease and/or poor vision. fifty eyes were included recurrent corneal erosion (rce): 25 eyes, salzmann’s nodular degeneration: 9 eyes, spheroidal degeneration: ...

PURPOSE To investigate the effect of annexin A5, a calcium-dependent phospholipid-binding protein, on corneal epithelial wound healing. METHODS The effect of annexin A5 on migration of rabbit corneal epithelial (RCE) cells in vitro was examined in scrape-wounded cell monolayers. The effect of annexin A5 on the release of urokinase-type plasminogen activator (uPA) from cultured RCE cells was d...
