Cuticular hydrocarbon profiles in Blattella germanica: effects of halofenozide, boric acid and benfuracarb
2006
1379-1176 (Print) Journal Article; In order to complete previous studies conducted on Blattella germanica, three insecticides from different groups were evaluated: boric acid, an inorganic compound, benfuracarb, a carbamate, and halofenozide, a non-steroidal ecdysone agonist. Boric acid (8.20%, LD50) and benfuracarb (2%, LD50) were incorporated into the diet and orally administrated to newly emerged adults of both sexes, while halofenozide (0.33%, LD50) was applied topically. Hydrocarbons extracts was made on bidistilled pentane from control and treated series sampled 6 days following treatment. Extracts was analyzed by gas chromatography. Data showed that cuticular profiles of control and …

Efficacy of levetiracetam in the treatment of drug-resistant Rett Syndrome.
2010
Rett syndrome (RTT) is a progressive neurological disorder characterized by a wide spectrum of phenotypes. Epilepsy is reported to occur in 50–90% of patients with RTT; some develop medically refractory epilepsy. The aim of this study is to investigate the efficacy of levetiracetam (LEV) in drug-resistant patients with RTT. This prospective, pragmatic, open-label study consisted of an 8-week baseline period and a 6-month evaluation period. Efficacy variable was the mean frequency of monthly seizures before, and after 3 and 6 months of treatment with LEV. Eight female patients, aged 7.5–19 years (M12.8 ± 5) entered the study. Mean age at epilepsy onset was 25.8 ± 14.1 months. All patients sh…
The Chandra COSMOS Survey, I: Overview and Point Source Catalog
2009
The Chandra COSMOS Survey (C-COSMOS) is a large, 1.8 Ms, Chandra} program that has imaged the central 0.5 sq.deg of the COSMOS field (centered at 10h, +02deg) with an effective exposure of ~160ksec, and an outer 0.4sq.deg. area with an effective exposure of ~80ksec. The limiting source detection depths are 1.9e-16 erg cm(-2) s(-1) in the Soft (0.5-2 keV) band, 7.3e(-16) erg cm^-2 s^-1 in the Hard (2-10 keV) band, and 5.7e(-16) erg cm(-2) s(-1) in the Full (0.5-10 keV) band. Here we describe the strategy, design and execution of the C-COSMOS survey, and present the catalog of 1761 point sources detected at a probability of being spurious of <2e(-5) (1655 in the Full, 1340 in the Soft, and…
PHOTOMETRY OF STARS FOR ASTRONEGATIVES WITH A SINGLE EXPOSURE
2019
The paper discusses the construction of characteristic curves for various astronegatives with a single exposure. Particular attention is paid to the question of extrapolation of the characteristic curve for the region of the weakest stars in the absence of standards. A new method for constructing an individual characteristic curve for digitized films and plates in the UBVR system has been proposed and implemented. The processing of frames of digitized plates and films with sky areas is car- ried out using LINUX/MIDAS/ROMAFOT software tools. ROMAFOT application allows us to extract astro- metric rectangular coordinates X,Y and photometric char- acteristics such as instrumental photometric ma…

NEW ASTROMETRIC REDUCTION OF THE SUPERCOSMOS PLATE ARCHIVE: FIRST RESULTS
2019
The arrivals of the new more accuracy reference catalogues and also development of new meth- ods and approaches for reduction astrometric data give the new life for photographic plates archives. Gaia DR2 is not only a giant step in the astrometric accuracy allowing to measure new objects also provides plates archives ob- served in the past with modern accuracy. In this work we present the first results of astrometric reduction in the sys- tem of Gaia DR2 for some photographic plates that were obtained by UK Schmidt telescope (UKST) and digitized by the SuperCOSMOS scanning machine. The UKST is a classical Schmidt with the following parameters: mirror diameter 1.83m; focal length 3.07m; phot…
Taisnīgums Platona dialogā "Valsts"
2018
Platona dialogs Valsts ir viens no nozīmīgākajiem antīkajiem filozofiskajiem darbiem, kurā izteiktās domas tiek apspriestas ļoti aktīvi vēl līdz mūsdienām. Veicot oriģinālteksta leksikas analīzi, kas izmantota taisnīguma jēdziena paskaidrošanā, bakalaura darbs pievēršas Platona izpratnei par taisnīgumu un tam, kā taisnīgums izpaužas gan cilvēkā, gan valstiskā veidojumā. Darbs veltīts Platona skatījumam uz valstī esošo kārtu – ražotāju, sargu un likumdevēju – dabisko izveidošanos, aplūkota to nozīme un vieta valstiskajā sistēmā un katras kārtas sava dabas noteiktā darba darīšana, nejaucoties svešos darbos. Šīs sistēmas saglabāšana ir atslēga taisnīguma nodrošināšanai valstī. Līdzīgi arī noti…

Reversion of 7-methylguanosine 5′-phosphate inhibition of mRNA translation by polysomal and soluble factors isolated from Saccharomyces cerevisiae
1987
Abstract Protein fractions that overcome m7GMP inhibition of mRNA translation have been purified from the yeast S. cerevisiae . An active fraction isolated from polysomes contains two polypeptides of 220- and 190-kDa. The active fraction isolated from postribosomal supernatant contains a major polypeptide of 28-kDa and other species of 32-, 24-, 22- and 21-kDa, and sediments in sucrose gradients as a high molecular weight complex of about 200000. This fraction restored yeast mRNA translation in reticulocyte lysates under conditions of yeast and globin mRNA competition; however, this effect was not observed with the 220- and 190-kDa polypeptides from polysomes. Nevertheless, translation of y…
