FOCAL LIVER LESIONS: CONTRAST-ENHANCED ULTRASOUND
2008
Contrast-enhanced ultrasound (CEUS) represents a significant breakthrough in sonography and it is being increasingly used for evaluation of focal liver lesions (FLLs). The unique feature of CEUS of non-invasively assessing in real time liver perfusion throughout the vascular phase has led to a dramatic improvement in diagnostic accuracy of US in either detection and characterization of FLLs, as well as in the guidance and evaluation of response of therapeutic procedures. Currently, CEUS is included as a part of the suggested diagnostic work-up of FLLs, resulting in a better patient management and cost-effective therapy delivering. After a brief description of the basis of different CEUS tec…
Resistant Microbial Cooccurrence Patterns Inferred by Network Topology
2015
ABSTRACT Although complex cooccurrence patterns have been described for microbes in natural communities, these patterns have scarcely been interpreted in the context of ecosystem functioning and stability. Here we constructed networks from species cooccurrences between pairs of microorganisms which were extracted from five individual aquatic time series, including a dystrophic and a eutrophic lake as well as an open ocean site. The resulting networks exhibited higher clustering coefficients, shorter path lengths, and higher average node degrees and levels of betweenness than those of random networks. Moreover, simulations demonstrated that taxa with a large number of cooccurrences and place…
Heavy Metal Contents in Soft-Bottom Marine Macrophytes and Sediments Along the Mediterranean Coast of Spain
2000
. Hg, Cd, Pb and Zn concentrations were determined in sediment and in tissues of five species of soft-bottom marine macrophytes (Posidonia oceanica, Cymodocea nodosa, Zostera noltii, Ruppia cirrhosa and Caulerpa prolifera) along the Spanish Mediterranean coast. Levels of metals were low in most of the sampling stations and similar to those found by other authors in uncontaminated zones. Certain locations, however, showed some degree of contamination (Cambrils, Almassora, Alacant, Mar Menor and El Portus). In Santa Pola we found high contents of metals in one sample of sediment due to the high proportion of the fine fraction (particules < 63µm) and organic matter, but not in the seagrass spe…
Health sector spending and spending on HIV/AIDS, tuberculosis, and malaria, and development assistance for health: progress towards Sustainable Devel…
2020
BACKGROUND: Sustainable Development Goal (SDG) 3 aims to "ensure healthy lives and promote well-being for all at all ages". While a substantial effort has been made to quantify progress towards SDG3, less research has focused on tracking spending towards this goal. We used spending estimates to measure progress in financing the priority areas of SDG3, examine the association between outcomes and financing, and identify where resource gains are most needed to achieve the SDG3 indicators for which data are available. METHODS: We estimated domestic health spending, disaggregated by source (government, out-of-pocket, and prepaid private) from 1995 to 2017 for 195 countries and territories. For …
Survey of organochlorines in Finnish watercourses by caged mussel method
2002
Monitoring organochlorine compounds with caged common lake mussels (Anodonta piscinalis) in the pulp and paper mill recipient watercourses of Finland annually from 1984 produced many statistically significant time trends. A decrease of chlorophenols and chloroguaiacols originating from chlorobleaching were observed in all recipients in parallel with the decreasing discharges from the mills. Metabolites of chlorophenols, chloroanisoles and chloroveratroles were constant. Significantly elevated PCB concentrations were measured in four watercourses. At two of these areas, the PCB concentrations were constant. In contrast, a statistically significant increase of PCB (and DDE) was found at one r…
A branch & bound algorithm for cutting and packing irregularly shaped pieces
2013
Abstract Cutting and packing problems involving irregular shapes, usually known as Nesting Problems, are common in industries ranging from clothing and footwear to furniture and shipbuilding. Research publications on these problems are relatively scarce compared with other cutting and packing problems with rectangular shapes, and are focused mostly on heuristic approaches. In this paper we make a systematic study of the problem and develop an exact Branch & Bound Algorithm. The initial existing mixed integer formulations are reviewed, tested and used as a starting point to develop a new and more efficient formulation. We also study several branching strategies, lower bounds and procedures f…
Hypohidrotic Ectodermal Dysplasia with total anodontia: A case report
2011
Ectodermal dysplasia is a hereditary disorder that occurs as a consequence of disturbances in the ectoderm of the developing embryo. The triad of nail dystrophy, alopecia or hypotrichosis and palmoplantar hyperkeratosis is usually accompanied by a lack of sweat glands and a partial or complete absence of primary and/ or permanent dentition. A case report illustrating the prosthetic rehabilitation of a seven year old boy with hypohidrotic ectodermal dysplasia associated with total anodontia is presented.
Divu scenāriju prognoze par ES nodarbinātības mērķa sasniegšanu Baltijas valstīs un nodarbinātības līmeņi sievietēm un vīriešiem 2020.gadā
2017
Šis pētījums ir vērsts uz stratēģijas Eiropa 2020 valsts nodarbinātības līmeņa mērķiem Baltijas valstīs - Latvijā, Lietuvā un Igaunijā. Izveidota nodarbinātības līmeņa prognoze, kas balstīta uz regresijām, kuru iegūtie koeficienti tiek izmantoti nodarbinātības vienādojumam. Šī prognoze tiek iegūta visām trim Baltijas valstīm un visu trīs valstu sieviešu un vīriešu nodarbinātībai. Prognozei pētījums piedāvā divus scenārijus: optimistisku un pesimistisku. Pētījuma rezultāti rāda, ka optimistiskā scenārijā visas valstis ne tikai izpilda, bet pat pārsniedz uzstādītos mērķus. Pesimistiskajā scenārijā nevienai no trim valstīm neizdodas sasniegt noteikto mērķi. Gan vīriešiem, gan sievietēm nodarbi…

2020
Diplomdarba tēma „Nekustamā īpašuma nodoklis Latvijā un Eiropas Savienībā”. Darba mērķis ir izpētīt un veikt analīzi par problemātiskiem nekustamā īpašuma nodokļa aspektiem Latvijā un veikt salīdzinošo analīzi par nekustamo īpašuma nodokli citās Eiropas Savienības dalībvalstīs, kā arī tuvāk iepazīties ar Latvijas nekustamā īpašuma nodokli, tā bāzi, objektu, subjektu, likmi, atvieglojumiem, kā arī izskatīt kadastrālās vērtības risinājumu piemērus un novērtēt, kādu ienākumu saņem valsts no nekustamā īpašuma nodokļa. Mērķa sasniegšanai autorе izvirza šādus uzdevumus: analizēt teorētisko literatūru par nodokļu vispārīgu būtību; analizēt problēmas kadastrālajās vērtībās, kadastrālās vērtības apr…
Pievienotās vērtības nodoklis un ar šo nodokli saistītā krāpšana Latvijā un Eiropas Savienībā
2018
Darbā ir pētīts pievienotās vērtības nodoklis Latvijā un ES. Pievienotās vērtības nodoklis tiek uzskatīts par sarežģītāko nodokli, tādēļ ir nepieciešams skaidri un vienkārši noteikt nodokļa piemērošanu. Pamatojoties uz PVN teorētisko aspektu raksturojumu izpētīt ar šo nodokli saistīto krāpšanu Latvijā un Eiropas Savienībā un izstrādāt priekšlikumus konstatēto nepilnību risināšanai Darbā tiek analizēta Latvijas likumdošana par nodokļa piemērošanu un tās attīstība, kā arī veikta tā salīdzināšana ar citu Eiropas Savienības dalībvalstu pieredzi.
