<B>Graphic Abstract</B> <P>The cover shows an image of fully rollable transparent nanogenerators synthesized using chemical vapor deposition grown large-scale graphene sheets as transparent electrodes and piezoelectric ZnO nanorod arrays. Sang-Woo Kim, Jae-Young Choi, and co-workers report on p. 2187 the electrical and structural stability of the nanogenerators, with excellent charge scavenging performance under external mechanical loads such as bending and rolling. This study shows that graphene-based nanogenerators are very promising for self-powered rollable transparent device applications. <img src='wiley_img_2010/09359648-2010-22-19-ADMA201090066-content.gif' alt='wiley_img_2010/09359648-2010-22-19-ADMA201090066-content'> </P>

To survey the mouse microbiological contamination rate in Korean animal facilities, we tested for common contaminants in these facilities using serological, culture, and parasitological methods. A total of 21,292 experimentally housed mice from 206 animal facilities, including hospitals, universities, companies and research institutes, were tested over a 6-year period from 2014 to 2019. The most commonly found contaminants were various species of non-pathogenic protozoa (47.2%). The most common pathogenic bacteria were Staphylococcus aureus (21.2%), Pasteurella pneumotropica (12.5%) and Pseudomonas aeruginosa (5.8%). Mouse hepatitis virus (6.1%) was detected, but no other viral or bacterial pathogens were found. These results establish that the main pathogens that currently contaminate animal facilities in Korea are opportunistic pathogens, whereas important such as those in categories B or C, were decreased.
0.7 inch FED Panel system build - up by using proper sealing process
Sang Jik Kwon,Kun Jo Hong,Tae Hee Cho,Jong Duk Lee,Chang Woo Oh,Yong Bum Kwon 한국진공학회(ASCT) 1999 Journal of Korean Vacuum Science & Technology Vol.3 No.1
FED panel was successfully fabricated through the integration of a 0.7″ diagonal Si-based Mo-tip FEA with 25×25 pixels, Y₂O₃:Eu or ZnO:Zn phosphor screen, and vacuum sealing through an exhausting glass tube, including a getter. The panel system was driven by an external driver circuit having pulse width modulation(PWM) driving scheme. Before character imaging, it was stabilized through tip aging by slowly increasing a pulse-mode emission current and phosphor aging by a coulombic charging process. After aging, luminescent characteristics such as emission uniformity, charging and arcing phenomena were shown to be improved significantly.

Skeletal muscle atrophy is characterized by a reduction of muscle mass with excessive protein degradation. High-fat/high-sucrose (HFHS) diet is recently reported to accelerate a muscle wasting. We previously reported that peanut sprout extract (PSE) prevented diet-induced obesity and identified p-coumaric acid (PCA) is a main component of PSE to mimic lipid-lowering effects of PSE. However, it is still unknown whether PSE and/or PCA prevent muscle atrophy in animal model. To answer this question, C57BL/6 male mice were orally administrated PSE or PCA (10 mg/kg BW) with low-fat diet (LF, 11% kcal fat) or HFHS (60% kcal fat) for 10 weeks. In the last 6 days, dexamethasone (DEX) was treated establishing five groups: (i) CON, (ii) Dex, (iii) Dex+HFHS, (ⅳ) Dex+HFHS+PSE, and (ⅴ) Dex+HFHS+PCA. Dex+HFHS significantly reduced grip strength and hanging capacity which indicated worsening muscle atrophy by HFHS compared to CON. PSE and PCA reduced the muscle atrophy factors (MuRF1, Atrogin-1), while increased the holding impulse and mitochondrial factors (TFAM, CyCS, PGC1α). Collectively, PSE and PCA inhibited HFHS and DEX-induced muscle atrophy with mitochondrial activation.

<P><B>Abstract</B></P> <P>The feasibility of ohmic heating for cooking instant noodles was evaluated using a customized ohmic system. Temperature come-up time, heat transfer ratio (<I>HT</I> <SUB> <I>nls</I> </SUB>), system performance coefficient (<I>SPC</I>), and textural qualities were evaluated as a function of different electric fields (10, 12.5, 15, and 17.5 V/cm) and temperature holding times (30, 60, 90, and 120 s). Temperature come-up time to 100 °C was 3.9 ± 0.1, 2.5 ± 0.1, 2.1 ± 0.2, and 1.3 ± 0.1 min at electric fields of 10, 12.5, 15 and 17.5 V/cm, respectively.

<P><B>Abstract</B></P> <P>The concentrations and fluxes of airborne phthalates were measured from five types of polyvinyl chloride (PVC) consumer products (vinyl flooring, wallcovering, child's toy, yoga mat, and edge protector) using a small chamber (impinger) system. Airborne phthalates released from each of those PVC samples were collected using sorbent (Tenax TA) tubes at three temperature control intervals (0, 3, and 6 h) under varying temperature conditions (25, 40, and 90 °C). A total of 11 phthalate compounds were quantified in the five PVC products examined in this study. To facilitate the comparison of phthalate emissions among PVC samples, their flux values were defined for total phthalates by summing the average fluxes of all 11 phthalates generated during the control period of 6 h. The highest flux values were seen in the edge protector sample at all temperatures (0.40 (25 °C), 9.65 (40 °C), and 75.7 μg m<SUP>−2</SUP> h<SUP>−1</SUP> (90 °C)) of which emission was dominated by dibutyl isophthalate. In contrast, the lowest fluxes were found in wallcovering (0.01 (25 °C) and 0.05 μg m<SUP>−2</SUP> h<SUP>−1</SUP> (40 °C)) and child's toy (0.23 μg m<SUP>−2</SUP> h<SUP>−1</SUP> (90 °C)) at each temperature level. The information regarding phthalate composition and emission patterns varied dynamically with type of PVC sample, controlled temperature, and duration of control.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Enhanced levels of semi-volatile organic compounds (SVOCs) can affect human health. </LI> <LI> The major SVOCs like phthalates are released into indoor by many sources like plasticizers. </LI> <LI> This study investigated the emission characteristics of diverse phthalates from plastic/rubber products. </LI> <LI> Emission behavior of phthalates is described in relation to several key variables, e.g., types of PVC. </LI> </UL> </P>
