Devona Šķerveļa svītas dolokrēti atsegumos Ventas un Šķerveļa krastos
2018
Maģistra darbā ir raksturota augšējā devona Šķerveļa svītas uzbūve un sastāvs Šķerveļa upes kreisā krasta un Ātrā kalna atsegumos. Izveidoti slāņkopas ģeoloģiskie griezumi, veikta nogulumiežu tekstūru analīze griezumos, pieslīpņos un plānslīpējumos, granulometriskā un stabilo izotopu analīze. Pētījumu rezultātā noskaidrots, ka Šķerveļa svītas nogulumieži sākotnēji ir veidojušies kā klastiskie nogulumi fluviālos apstākļos un pēc tam subaerālos apstākļos dažādā pakāpē notikusi to pārveidošanās par karbonātu garozām. Tādas plānslīpējumos novērotas mikrotekstūras kā mikrītiska dolomīta kunkuļi, “peldošo” kvarca graudu tekstūras, sīkslāņotās josliņas un pizoīdi, bieži sakārtoti arī apgrieztajā g…
Beam-induced and cosmic-ray backgrounds observed in the ATLAS detector during the LHC 2012 proton-proton running period
2016
This paper discusses various observations on beam-induced and cosmic-ray backgrounds in the ATLAS detector during the LHC 2012 proton-proton run. Building on published results based on 2011 data, the correlations between background and residual pressure of the beam vacuum are revisited. Ghost charge evolution over 2012 and its role for backgrounds are evaluated. New methods to monitor ghost charge with beam-gas rates are presented and observations of LHC abort gap population by ghost charge are discussed in detail. Fake jets from colliding bunches and from ghost charge are analysed with improved methods, showing that ghost charge in individual radio-frequency buckets of the LHC can be resol…
Translation ‘going social’? Challenges to the (Ivory) Tower of Babel
2010
The discussion of “turns” or “paradigmatic shifts” which we can witness in the last few years in Translation Studies undoubtedly testifies to the discipline’s increasing establishment and recognition within the scientific community and of the increasing practice of a transdisciplinary research. These shifts also include what has been called the “sociological turn”, which comprises the cluster of questions dealing not only with the networks of agents and agencies and the interplay of their power relations, but also the social discursive practices which mould the translation process and which decisively affect the strategies of a text to be translated. This paper seeks to foreground some of t…
The “genetic erosion” of the soil ecosystem
2013
Abstract This paper takes into consideration the influence of human activities on the loss of pedodiversity in a Mediterranean area due to large scale farming. In particular it examines the quantitative and qualitative soil changes in a period of 53 years (from 1955 to 2008) evaluating the loss of soil diversity at soil subgroups level of the USDA Soil Taxonomy system. The following indices were used: richness; Shannon’s diversity index; Simpson diversity index; Shannon’s evenness index; Simpson’s evenness index. In this case study, considering what we observed in time, the human intervention in soil transformation could increase the diversity in the landscape in an initial phase, but forwa…
