Incorporation of nitrogen in Li2O-B2O3 glasses by conventional melting and via different sol-gel routes

Nitrogen-containing Li2O—B2O3 glasses were prepared by six different melting and sol-gel processes. As pre-products conventional batches as well as dried gels were used, and the gels were prepared from aqueous or from alkoxide solutions. The nitrogen was brought into the glasses by adding BN, Li3N or NH3 at different stages of the procedure. The atmosphere during melting, the melting temperature and the melting time were also varied. The mtrogen-containing products were analyzed with respect to chemical composition and to glassiness. The amount of nitrogen dissolved was determined by means of the Kjeldahl method. The dependence of the nitrogen content obtained is discussed with respect to the methods apphed and the parameters varied. Compared to silicate and phosphate glass systems much less nitrogen could be introduced into the lithium borate glasses studied here. The maximum amount of nitrogen which is actually built into the borate glass network is 0.34 wt%

Does Animal Personality Affect Movement in Habitat Corridors? Experiments with Common Voles (Microtus arvalis) using Different Corridor Widths.

Kowalski GJ, Grimm V, Herde A, Günther A, Eccard JA. Does Animal Personality Affect Movement in Habitat Corridors? Experiments with Common Voles (Microtus arvalis) using Different Corridor Widths. Animals : an open access journal from MDPI. 2019;9(6): 291.Animal personality may affect an animal's mobility in a given landscape, influencing its propensity to take risks in an unknown environment. We investigated the mobility of translocated common voles in two corridor systems 60 m in length and differing in width (1 m and 3 m). Voles were behaviorally phenotyped in repeated open field and barrier tests. Observed behavioral traits were highly repeatable and described by a continuous personality score. Subsequently, animals were tracked via an automated very high frequency (VHF) telemetry radio tracking system to monitor their movement patterns in the corridor system. Although personality did not explain movement patterns, corridor width determined the amount of time spent in the habitat corridor. Voles in the narrow corridor system entered the corridor faster and spent less time in the corridor than animals in the wide corridor. Thus, landscape features seem to affect movement patterns more strongly than personality. Meanwhile, site characteristics, such as corridor width, could prove to be highly important when designing corridors for conservation, with narrow corridors facilitating faster movement through landscapes than wider corridors

Разработка агрегатора данных о погоде и прогнозов погоды

Nowadays we frequently can't say which clothes weshould wear tomorrow. The problem is that there is no weather forecast service which can provide us exact weather forecast even for tomorrow, needless to say about further future. Main purpose of this work is to design system that will predict which weather forecast service should be used today to know weather for tomorrow. Authors suggest to evaluate forecasting value of temperature relying on statistics. They describe steps which they need to pass to achieve the purpose. As a result authors want to develop software which can provide weather forecast with higher probability than all existing services

Application of magnetic resonance imaging in transgenic and chemical mouse models of hepatocellular carcinoma

<p>Abstract</p> <p>Background</p> <p>Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide. The molecular mechanisms underlying hepatocarcinogenesis are still poorly understood. Genetically modified mice are powerful tools to further investigate the mechanisms of HCC development. However, this approach is limited due to the lack of non-invasive detection methods in small rodents. The aim of this study was to establish a protocol for the non-invasive analysis of hepatocarcinogenesis in transgenic mice using a clinical 1.5 Tesla Magnetic Resonance Imaging scanner.</p> <p>Results</p> <p>As a model system we used hepatocyte-specific c-myc transgenic mice developing hepatocellular carcinoma at the age of 12-15 months. The scans of the murine livers included axial T2-weighted turbo-spin echo (TSE) images, axial T1-weighted and contrast enhanced T1-weighted gradient echo (fast field echo, FFE) and sagittal true Fast Imaging with Steady state Precession (true-FISP) images. Application of contrast agent was performed via tail vein-catheter and confirmed by evaluation of the altered longitudinal relaxation T1 time before and after application. Through technical adaptation and optimization we could detect murine liver lesions with a minimum diameter of approximately 2 mm and provided histopathological evidence that these MR findings correspond to hepatocellular carcinoma. Tumor growth was repeatedly measured using sequential MRI with intervals of 5 weeks and subsequent volumetric analysis facilitating direct comparison of tumor progression between individual animals. We finally demonstrated that our protocol is also applicable in the widely- used chemical model of N-nitrosodiethylamine-induced hepatocarcinogenesis.</p> <p>Conclusion</p> <p>Our protocol allows the non-invasive, early detection of HCC and the subsequent continuous monitoring of liver tumorgenesis in transgenic mice thereby facilitating future investigations of transgenic tumor mouse models of the liver.</p
