The paper reviews the problems of measurement of sheet resistance of ultrathin high-resistance layers of organic semiconductors and the essential underlying problems. Particular attention is paid to potential influence of the resistance of contact regions on the results of direct measurement of sheet resistance of stripe-shaped layers. In this connection, we present a methodology of double length stripe resistance measurement (DLSRM), used above all to minimise the influence of contact regions on the measurement results. We deduce theoretical as well as practical possibilities of DLSRM in the diagnostics and quantitative characterisation of unsuitable or even faulty contacts on high-resistance layers. The application efficiency of the DLSRM method is documented by the results of sheet resistance measurement on zinc phthalocyanine with cathode sputtered planar contacts of noble metals (gold, platinum, or palladium). As expected, gold is the best contact material, but even in its application one cannot neglect the influence of contact regions. The presented method is universal and generally applicable to all materials where sheet resistance is the relevant parameter, and its assessment is based on measurements of the layer resistance in stripe arrangement.

Approximately 80 million US adults-one in four-are infected with the human papillomavirus (HPV), which causes cancers of the cervix in women, cancers of the anus, penis, and throat in men, and genital warts in both sexes. Although HPV vaccinations are safe, effective, easily affordable, and readily available, a substantial percentage of parents resist recommendations to vaccinate their children against HPV. The current study tests the effects of different vaccination advocacy message strategies on attitudes toward HPV vaccination.

Groundwater is widely threatened by hazardous manganese and ammonia. In present study, a novel gravity-driven fixed-bed ceramic membrane filtration (GDFBCM) with critical PAC-MnOx-ceramsite filters was built to address these issues. Static ceramsite filters in GDCM significantly increased membrane flux from 11 L/m·h to 18 L/m·h on the 50th day of filtration.
