Vēsturiskās pilsētas ainavas pieeja kultūras mantojuma saglabāšanai Kuldīgā
2015
Kuldīgas vēsturiskajā centrā kultūras mantojums sastopams visplašākajā tā izpratnē. Jau desmit gadu pašvaldība praktizē plānveidīgas kultūras mantojuma pārvaldības aktivitātes, kas pamanītas un atzinīgi novērtētas ne tikai Latvijā, bet arī starptautiski. Tomēr pilsētvide ir dzīva un mainīga, demonstrējot spēju tapt pielāgotai sabiedrības vajadzībām un kalpot tai. Arī kultūras mantojuma aizsardzībai un saglabāšanai tādai vajadzētu būt – visaptverošai, ar ilgtspējīgu vēsturiskās pilsētvides pārvaldību un integrētai vispārējā pilsētas attīstības ietvarā. Šī pētījuma mērķis ir izstrādāt priekšlikumus Kuldīgas kultūras mantojuma pārvaldības pilnveidošanai, balstoties teorētiskajās atziņās par vē…
.NET ietvara bibliotēku dekompilēšana
2015
Darba mēŗkis ir pētīt, kā notiek .NET ietvara bibliotēku dekompilēšana – jānoskaidro, kā notiek kompilēšanas un dekompilēšanas process, jāmēģina iegūt sākotnējais pirmkods, izveidojot tam paredzētu lietotni. Galvenais mērķis ir izveidot lietotni – apskatīt, kāda veida aizsardzība var būt pielietojama, lai pasargātu no dekompilēšanas. Darbā tiek pētīts .NET ietvara kompilācijas un dekompilācijas process un tiek iegūta lietotne, kura spēj dekompilēt vienkāršākos C# valodas sintakses fragmentus. Ir veikts pētījums par publiski pieejamu dekompilācijas lietotni, kurai bija pieejams pirmkods, lai varētu noskaidrotu, kā strādā pilnīgas dekompilācijas lietotnes.
Estimating the macroscopic capillary length from Beerkan infiltration experiments and its impact on saturated soil hydraulic conductivity predictions
2020
International audience; The macroscopic capillary length, λc, is a fundamental soil parameter expressing the relative importance of the capillary over gravity forces during water movement in unsaturated soil. In this investigation, we propose a simple field method for estimating λc using only a single-ring infiltration experiment of the Beerkan type and measurements of initial and saturated soil water contents. We assumed that the intercept of the linear regression fitted to the steady-state portion of the experimental infiltration curve could be used as a reliable predictor of λc. This hypothesis was validated by assessing the proposed calculation approach using both analytical and field d…
Processing and Assessment of Spectrometric, Stereoscopic Imagery Collected Using a Lightweight UAV Spectral Camera for Precision Agriculture
2013
Imaging using lightweight, unmanned airborne vehicles (UAVs) is one of the most rapidly developing fields in remote sensing technology. The new, tunable, Fabry-Perot interferometer-based (FPI) spectral camera, which weighs less than 700 g, makes it possible to collect spectrometric image blocks with stereoscopic overlaps using light-weight UAV platforms. This new technology is highly relevant, because it opens up new possibilities for measuring and monitoring the environment, which is becoming increasingly important for many environmental challenges. Our objectives were to investigate the processing and use of this new type of image data in precision agriculture. We developed the entire pro…
The ELSA tephra stack: Volcanic activity in the Eifel during the last 500,000 years
2016
Abstract Tephra layers of individual volcanic eruptions are traced in several cores from Eifel maar lakes, drilled between 1998 and 2014 by the Eifel Laminated Sediment Archive (ELSA). All sediment cores are dated by 14C and tuned to the Greenland interstadial succession. Tephra layers were characterized by the petrographic composition of basement rock fragments, glass shards and characteristic volcanic minerals. 10 marker tephra, including the well-established Laacher See Tephra and Dumpelmaar Tephra can be identified in the cores spanning the last glacial cycle. Older cores down to the beginning of the Elsterian, show numerous tephra sourced from Strombolian and phreatomagmatic eruptions,…

Carbon, nitrogen and oxygen isotope fractionation during food cooking: Implications for the interpretation of the fossil human record.
2017
13 pages; International audience; ObjectivesStable isotope data provide insight into the reconstruction of ancient human diet. However, cooking may alter the original stable isotope compositions of food due to losses and modifications of biochemical and water components.MethodsTo address this issue, carbon, nitrogen and oxygen isotope ratios were measured on meat aliquots sampled from various animals such as pork, beef, duck and chicken, and also from the flesh of fishes such as salmon, European seabass, European pilchard, sole, gilt-head bream, and tuna. For each specimen, three pieces were cooked according to the three most commonly-known cooking practices: boiling, frying and roasting on…
Carbonate slope re‐sedimentation in a tectonically‐active setting (Western Sicily Cretaceous Escarpment, Italy)
2020
Tectonic processes are widely considered as a mechanism causing carbonate platform margin instabilities leading to the emplacement of mass transport deposits and calciturbidites. However, only few examples establishing a clear link between tectonics and re-sedimentation processes are known from the lit- erature. The two-dimensional and three-dimensional wire-cut walls of hun- dreds of quarries extracting ornamental limestones (for example, Perlato di Sicilia) from the Western Sicily Cretaceous Escarpment in Italy expose a series of mass transport deposits. The depositional architecture, spatial facies distri- bution and sedimentary features of these deposits were studied in detail. Thin sec…
The stoichiometry of particulate nutrients in Lake Tanganyika — implications for nutrient limitation of phytoplankton
1999
We studied the potential nutrient limitation of phytoplankton by means of seston nutrient stoichiometry and nutrient enrichment bioassays in the epilimnion of Lake Tanganyika. In most cases, the particulate carbon to phosphorus (C:P) ratio was high and indicated moderate P deficiency, while the respective C:N ratio mainly suggested moderate N deficiency. The N:P ratios of seston indicated rather balanced N and P supply. In three two-day enrichment bioassays in April—May 1995, a combined addition of P, N and organic carbon (glucose) always increased primary production in comparison to untreated controls. Primary production also slightly increased after the addition of phosphate-P, while the …
