Data from: Plant – herbivorous beetle networks: molecular characterization of trophic ecology within a threatened steppic environment
2015
DNA barcoding facilitates many evolutionary and ecological studies, including the examination of the dietary diversity of herbivores. In this study, we present a survey of ecological associations between herbivorous beetles and host plants from seriously threatened European steppic grasslands. We determined host plants for the majority (65%) of steppic leaf beetles (55 species) and weevils (59) known from central Europe using two barcodes (trnL and rbcL) and two sequencing strategies (Sanger for mono/oligophagous species and Illumina for polyphagous taxa). To better understand the ecological associations between steppic beetles and their host plants, we tested the hypothesis that leaf beetl…
Zemes mākslīgo pavadoņu novērošanas stacijas dežūru žurnāls Nr. 1, 1957–1958
2023
Raksts tapis par PSRS izgudrotu Zemes mākslīgo pavadoņu novērošanas stacijas dežūru žurnālu, kur uzskaitītas iesaistītās personas - pasniedzēji, zinātniskie asistenti un studenti no Pētera Stučkas Latvijas Valsts universitātes (LVU) Fizikas un matemātikas fakultātes. Novērošanas stacija atradās LVU Botāniskajā dārzā, kur bija iespējams veikt astronomiskos novērojumus. Lai kādas bija ieceres novērošanas stacijas attīstībai, studentu interese noplaka interešu trūkuma dēļ. Zemes mākslīgo pavadoņu novērošanas stacijas dežūru žurnāls Nr. 1, 1957–1958 pievienots atsevišķā datnē.
Penile Abflußvenenokklusion: Vergleich von erektiler Funktion und Kavernosometrie vor und nach perkutanen Eingriffen
1993
After percutaneous transpenile or retrograde venous occlusion for the treatment of a cavernous leak, the clinical results were correlated with cavernosometric flow measurements in 27 patients. In 15 patients, venous occlusion led to a reduction of the maintenance flow: in patients who showed improvement there was an average reduction of 30 ml/min, in those without improvement or deterioration it averaged 0.3 or 13 ml/min respectively. In 7 patients there was increased flow (up to +21 ml/min). One of these patients showed improved erectile function; the remaining 6 showed no change as was also the case in 5 other patients who had no change in cavernosometric measurements. Our findings sugges…
