A new potassium persulfate redox system has been investigated for the graft polymerization of vinyl monomers. In this study potassium persulfate system was used for initiation the polymerization. Graft polymerization of acrylonitrile (AN) onto starch (Sta) was carried out in aqueous solution using potassium persulfate (I) redox system. It was found that the percentage of grafting and rate of gr...

Oil–water separation using special wettability materials has received much attention due to its low energy consumption and high efficiency. Herein, a fluorine-free superhydrophobic cotton fabric (PDMS/STA-coated fabric) was successfully prepared by simple impregnation method hydroxyl-capped polydimethylsiloxane (PDMS-OH), tetraethoxysilane (TEOS), stearic acid (STA) as precursors. The investiga...

In this letter, a novel scheme is proposed to identify in finite time the value of an unknown output parameter for class nonlinear dynamical systems. Inspired by Super-Twisting Sliding Mode Algorithm (STA), identification problem solved innovative way, consisting two steps. An STA observer firstly designed track system output. Exploiting behaviour during sliding motion, second scheme, still ins...

Dear Editor, Sub-Tenon’s anesthesia (STA) is widely used for regional orbital anesthesia. Complications of STA are rare but include inferior rectus muscle restriction [1-3]. There have been no reports of inferior rectus restriction after STA in Korea. We encountered a patient with inferior rectus muscle restriction after STA who eventually required surgical treatment and report the case herein....

The DAF-7/TGF-b pathway in C. elegans interprets environmental signals relayed through amphid neurons and actively inhibits dauer formation during reproductive developmental growth [1, 2]. In metazoans, the STAT pathway interprets external stimuli through regulated tyrosine phosphorylation, nuclear translocation, and gene expression [3], but its importance for developmental commitment, particul...

Coverage areas of WLAN access points (APs) are usually overlapped so a WLAN station (STA) might be able to find several APs to attach in a WLAN hotspot. Experimental results indicate that a WLAN STA normally associates with an AP with the maximal signal strength and requests the bandwidth of the AP for establishing network connections. However, this kind of STA-centric association and bandwidth...

To determine the effects of EPA, stearidonic acid (STA) or g-linolenic acid (GLA) on immune outcomes, healthy male subjects consumed one of seven oil blends for 12 weeks. EPA consumption increased the EPA content of peripheral blood mononuclear cells (PBMC). Consumption of GLA (2·0 g/d) in the absence of STA or EPA increased di-homo-GLA content in PBMC. Neither STA nor its derivative 20 : 4n-3 ...

ment was recommended, but the patient initially refused. As the clinical findings did not change during follow-up, surgery was performed in August 2014. Restriction of the inferior rectus muscle of the left eye was confirmed through the forced duction test. During surgery, conjunctival scarring over the inferior rectus muscle was noted, in addition to a linear scar along the medial border of th...
