No full text<i>Hymenomonas uralensis</i> Ignatenko & Yatsenko-Stepanova <i>sp. nov.</i> (Fig. 15) <p>Coccoliths are elliptical muroliths. Each coccoliths composed of an organic base plate and calcified elements. The base of the coccolith (0.93–1.2 × 0.8–0.96 µm, n=15) has a jagged edge, followed by a tubular part with more or less straight sides and the expanding part (1.3–1.6 × 0.97–1.3 µm) is formed by overlapping elements. The height of the coccolith is 0.36–0.51 µm, the width of the rim is 0.22–0.3 µm. In most coccoliths a single rim element at each end of the coccolith is extended distally as a rectangular block protruding above the rim (width 0.18–0.33 µm, height 0.25–0.43 µm).</p> <p> <b>Type:</b> —The specimen with <i>Hymenomonas uralensis</i> coccoliths on SEM stub number 49_I_3 deposited at the Herbarium of the Steppe Institute of the Ural Branch of the Russian Academy of Sciences, Orenburg (ORIS).

Authentication based on secret-key generation
No full textWe present models for authentication in biometric settings. We could determine the trade-off between false-acceptance exponents and the so-called privacy-leakage rate. In this way we extend the Ahlswede-Csiszar secret-key generation result [1993] and more specifically the secret-key rate vs. privacy-leakage rate trade-off, studied by Ignatenko and Willems [2009]
Jomonlithus littoralis Inouye & Chihara 1983
No full text<i>Jomonlithus littoralis</i> Inouye & Chihara (Figs. 5–7) <p> The diameter of the coccolith-bearing cell is 10.5–12.0 µm. The surface of the cell is covered by small oval-shaped coccoliths (muroliths), 1.07–1.39 × 0.77–0.92 µm; rim width 0.11–0.17 µm, rim height 0.2–0.29 µm. The coccolith structure corresponds to the description of Probert <i>et al.</i> (2014) to that which is composed of an organic base plate scale with a lightly calcified rim made up of small rectangular inner and outer sub-elements.</p> <p>This species was observed from a backwater of the Ural River and Zhetykol Lake (see Table 2).</p>Published as part of <i>Ignatenko, Marina & Yatsenko-Stepanova, Tatyana, 2023, Coccolithophores in the algal flora from South Urals (Russia) with the description of a new Hymenomonas species, pp. 55-64 in Phytotaxa 609 (1)</i> on page 58, DOI: 10.11646/phytotaxa.609.1.5, <a href="http://zenodo.org/record/8254620">http://zenodo.org/record/8254620</a>
Facile Access to Isotopically Labelled Valylleucyl Anilides as Biomarkers for the Quantification of Hemoglobin Adducts to Toxic Electrophiles
No full textAn easy and efficient synthesis of valylleucyl anilide (HValLeuNHPh) and labelled HVal(C-13(5), N-15)LeuNHPh has been developed. Derivatization of these substances with oxirane, acrylonitrile, epichlorohydrin, glyceraldehyde and other aldehydes gives a series of reference substances and internal standards for the quantitative evaluation of human exposure to toxic electrophiles by quantitative determination of their hemoglobin adducts. Coupling of N-Z-N-Me-Val(C-13(5), N-15) OH with HLeuNHPh followed by hydrogenolysis affords NMe-Val(C-13(5),N-15 N)LeuNHPh for quantification of the exposure to methylating agents.
