Efficient finite-difference scheme for solving some heat transfer problems with convection in multilayer media
2000
Abstract An efficient finite-difference method for solving the heat transfer equation with piecewise discontinuous coefficients in a multilayer domain is developed. The method may be considered as a generalization of the finite-volumes method for the layered systems. We apply this method with the aim to reduce the 3D or 2D problem to the corresponding series of 2D or 1D problems. In the case of constant piecewise coefficients, we obtain the exact discrete approximation of the steady-state 1D boundary-value problem.
Experimental Investigation on Innovative Stress Sensors for Existing Masonry Structures Monitoring
2023
Historical masonry structures often suffer gradual deterioration that in many cases can compromise the safety levels and the operating conditions of the buildings. In this context, Structural Health Monitoring (SHM) is an effective tool for the prediction of the structural behaviour and the state of conservation of buildings. Although many monitoring systems have recently been proposed, there is a lack of practical application of low-cost systems. This paper presents an experimental study based on the use of two innovative stress sensors—capacitive stress sensor and ceramic stress sensor—for the monitoring of existing masonry elements. In order to reproduce the actual conditions of onsite m…
Vēja plūsmas Baltijas jūras Kurzemes piekrastē
2018
Meteoroloģisko novērojumu staciju dati Kurzemes Baltijas jūras piekrastē rāda, ka gada siltajā periodā (marts – oktobris) diennakts siltajā laikā vēja ātruma sadalījumam ir maksimumi, kas atbilst krastam paralēliem vējiem gan no ziemeļu, gan dienvidu virziena. 2013. gada 3. un 6. maijs tika izvēlēti tālākai analīzei. Tika veikta matemātiskā modelēšana izmantojot WRF (Weather Research and Forecast) modeli, kā arī novērojumu analīze, iekļaujot ASCAT attālinātās izpētes vēja ātruma un virziena mērījumus no satelīta. Rezultāti rāda, ka ziemeļu virziena plūsmas var izskaidrot ar piekrastes zemo līmeņu plūsmu (coastal low-level jet), bet dienvidu virziena plūsmas var skaidrot ar krastam paralēlaj…
Design of molecular imaging and theranostic agents for the detection and targeted therapy of cancers
2020
Despite significant advances in cancer detection and treatment, cancer is now the second leading cause of death worldwide. The aim of this thesis project was to design and optimize imaging agents for the diagnosis and/or therapy of various cancers.The first axis of this thesis focused on the development of a bimodal PET/fluorescence imaging agent capable of targeting neurotensin NTS1 receptors overexpressed in certain cancers. PET imaging would allow efficient detection of tumors and their metastases, while fluorescence imaging would facilitate the evaluation of tumor margins during surgery. Several compounds were synthesized, labelled with gallium-68 and studied in preclinical studies in a…
Carbon Nanodots as Functional Excipient to Develop Highly Stable and Smart PLGA Nanoparticles Useful in Cancer Theranostics
2020
Theranostic systems have attracted considerable attention for their multifunctional approach to cancer. Among these, carbon nanodots (CDs) emerged as luminescent nanomaterials due to their exceptional chemical properties, synthetic ease, biocompatibility, and for their photothermal and fluorescent properties useful in cancer photothermal therapy. However, premature renal excretion due to the small size of these particles limits their biomedical application. To overcome these limitations, here, hybrid poly(lactic-co-glycolic acid) (PLGA-CDs) nanoparticles with suitable size distribution and stability have been developed. CDs were decisive in the preparation of polymeric nanoparticles, not on…
Hip muscle function in patients with symptomatic femoroacetabular impingement
2014
Femoroacetabular impingement (FAI) is a pathomechanical process of the hip joint, which could lead to hip pain and functional disability. Aim of this thesis was to investigate hip muscle function in patients with a symptomatic FAI. Hip muscle function was first investigated before patients underwent any surgical treatment for managing FAI. It was shown that they present with reduced hip muscle strength (i.e., muscle weakness), probably due to hip muscle inhibition. Nevertheless, hip muscle weakness was not associated with exaggerated hip muscle fatigue. Hip muscle strength recovery was then evaluated in a series of patients after hip arthroscopy to treat FAI. These patients demonstrated a g…
Whole-lake experiments reveal the fate of terrestrial particulate organic carbon in benthic food webs of shallow lakes
2014
Lake ecosystems are strongly linked to their terrestrial surroundings by material and energy fluxes across ecosystem boundaries. However, the contribution of terrestrial particulate organic carbon (tPOC) from annual leaf fall to lake food webs has not yet been adequately traced and quantified. In this study, we conducted whole-lake experiments to trace artificially added tPOC through the food webs of two shallow lakes of similar eutrophic status, but featuring alternative stable regimes (macrophyte rich vs. phytoplankton dominated). Lakes were divided with a curtain, and maize (Zea mays) leaves were added, as an isotopically distinct tPOC source, into one half of each lake. To estimate the …
An innovative method to produce green table olives based on "pied de cuve" technology
2015
The technology of “pied de cuve” (PdC) is applied in food process only to produce wines with an enriched community of pro-technological yeasts. PdC promotes the growth of the desirable microbial strains in a small volume of grape must acting as a starter inoculums for higher volumes. The aim of the present work was to investigate the use of partially fermented brines, a technology known as PdC, developed with lactic acid bacteria (LAB) on the microbiological, chemical and sensory characteristics of green fermented table olives during two consecutive campaigns. The experimental plan included two trials based on different PdCs: trial A, PdC obtained with Lactobacillus pentosus OM13; trial B, …
