Kora brzozy brodawkowatej jako biomonitor zanieczyszczenia powietrza metalami ciężkimi
2018
Celem przeprowadzonych badań była ocena możliwości wykorzystania kory brzozy brodawkowatej (Betula pendula Roth) w biomonitoringu terenów leśnych. Do badań wykorzystano korę drzew rosnących na obszarze Beskidów i Puszczy Boreckiej. W korze, metodą absorpcyjnej spektrometrii atomowej ze wzbudzeniem w płomieniu (F-AAS), oznaczono stężenia metali ciężkich: Mn, Fe, Ni, Cu, Zn, Cd oraz Pb. Na podstawie przeprowadzonych badań stwierdzono sezonowe zmiany stężenia analitów. Wykazano również, że kora brzozy brodawkowatej może być wykorzystywana jako bioindykator do oceny zanieczyszczenia aerozolu atmosferycznego na tych obszarach np. metalami ciężkimi. Ważne jest jednak, aby dokonać walidacji poszcz…
Buone prassi traduttive dei termini del linguaggio medico nelle opere di Galdós: l’esempio di "Fortunata y Jacinta"
2021
In this paper, through the study of some terms present in the novel Fortunata y Jacinta by Galdós that refer to the medical and pharmaceutical field, we want to carry out a reflection on some ‘best practices’ that the translator can use in his rewriting work, considered as the result of a cognitive operation, a complex intrigue of acquisition, categorization, reflective observation, elaboration, experimentation and creation of emotional-motivational dynamics which has, as its ultimate product, the recreation of the metatext. These 'best practices' fall to all intents and purposes in the topics to be treated within a teaching of translation with a neurolinguistic slant. In quest’articolo, at…
Y hromosomas ģenētisko variāciju salīdzinājums baltu un austrumslāvu populācijās
2016
Maģistra darbs ir veltīts austrumslāvu populāciju Y hromosomas ģenētiskās struktūras īpatnību noteikšanai un iegūto rezultātu salīdzinājumam ar baltu un ziemeļaustrumu Eiropas populācijām. Pētījuma ietvaros tika noteikta Y hromosomas haplogrupu izplatība Kijevas un Novgorodas apgabala populācijās. Iegūtie rezultāti norāda, ka Kijevas apgabalā visizplatītākā haplogrupa ir R1a (39,71%), bet Novgorodas apgabalā – N1c (74,32%). Detalizējot rezultātus ar PCA un filoģenētisko Neighbour-Joining analīzi, tika noteikts, ka Novgorodas apgabala populācija ģenētiski atrodas vistuvāk somiem augstās N1c haplogrupas izplatības dēļ, savukārt, pēc R1a-M558 atzara izplatības pētītajā teritorijā, autore secin…
LU Bibliotēkas mobilās lietotnes koncepcija
2020
Bakalaura darba temats ir Latvijas Universitātes Bibliotēkas mobilās lietotnes nepieciešamība, tās potenciālais saturs un vizuālais izskats. Darba mērķis ir izstrādāt saturisku un vizuālu Latvijas Universitātes Bibliotēkas mobilās lietotnes koncepciju. Darbs ir balstīts uz pragmatisma teoriju, lietotājcentrēta dizaina paradigmu un Alana Kūpera formulētajiem vizuālā dizaina integrācijas pamatprincipiem. Lai sasniegtu mērķi, tika veikta Latvijas Universitātes studentu un Latvijas Universitātes Bibliotēkas darbinieku anketēšana. Balstoties uz tās rezultātiem, izmantojot struktūrskicēšanas metodi, tika izveidota Latvijas Universitātes Bibliotēkas mobilās lietotnes koncepcija.
Nanofibrillar scaffold resists to bile and urine action: experiences in pigs
2020
Biomaterial-based-scaffolds’ functions are to replace anatomical and functional features loss of an injured tissue. They can replace native tissue after their reabsorption. Material and methods. In our experimental procedures we utilized the PHEA-PLA+PCL scaffold in 2 female pigs to assess its resistance to bile and urine. Results. Both pigs survived to surgical procedures. After a month fibres appeared unchanged in term of form and dimension at electronic microscopy. Cells and ECM factors were founded inside the scaffold in a microscopical evaluation. Conclusion. Planar and tubular scaffolds were colonized by cells and extracellular matrix elements. The study conducted on pig suggested tha…

A High Sensitive Nested PCR for Toxoplasma gondii Detection in Animal and Food Samples
2013
Toxoplasma gondii is a major food and waterborne transmitted parasite world-wide. The tissues and meat samples of many warm blooded animals can contain tissues cysts from chronic toxoplasmosis. Water and vegetable can be contaminated by the parasitic oocysts shed through the feces of infected cats, representing the definitive host of the parasite. A sensitive PCR for Toxoplasma gondii detection is described. The first step amplified the region between the 28S and 18S rDNA in the closely related T. gondii and Neospora caninum; RFLP analysis distinguished the DNA from the two morphologically identical parasites. Although N. caninum is not involved in human transmission, so far, it is importan…
Differential responses of bacterial and archaeal groups at high taxonomical ranks to soil management
2010
Little is known about abundances of the major bacterial taxa in agricultural soils and how they are affected by fertilization or other agricultural practices. Our aim was to determine the abundance and relative distribution of several bacterial phyla and one class, as well as the archaeal and crenarchaeal communities, and how they were affected by different fertilization regimes to examine whether specific responses of microorganisms could be identified at these high taxonomic ranks. We used real-time PCR with taxa specific primers to quantify the abundance of the Actinobacteria, Acidobacteria, Bacteriodetes, Firmicutes, Gemmatimonadetes, Verrucomicrobia, Alphaproteobacteria and Crenarchaeo…
DNA barcoding for Arecaceae and Fabaceae species identification of two plant collections
2021
DNA barcoding is a well-known technique that enable species identification by using universal DNA sequences from a small fragment of the genome. In this work, the effectiveness of DNA barcoding approach was evaluated in order to identify different taxonomic groups among two families (Arecaceae and Fabaceae) from two flowering plant collections: some were economically important taxa from nursery production and Mediterranean plants with ornamental attitude for possible new introduction. Three chloroplast DNA barcode regions (matK, rbcL and trnH-psbA) proposed by the Consortium for the Barcode of Life (CBOL) were tested in 22 Arecaceae species and in eight Fabaceae species, including Ceratonia…
