Stilistiskie izteiksmes līdzekļi pārtikas produktu reklāmas plakātos
2021
Bakalaura darba tiek pētīti stilistiski līdzekļi ar pārtiku saistītās drukas reklāmās. Reklāma ir īpaši nozīmīga un izplatīta mūsdienu sabiedrībā, tāpat kā nepieciešamība pēc zinātniskiem pētījumiem un izpratne par tās ietekmes sfērām, kas lielā mērā nosaka reklāmas tekstu lingvistiskās un stilistiskās iezīmes. Darbā tiek pētīti stilistiski pārtikas produktu reklāmas līdzekļi, ko izmanto vadošie starptautiskie pārtikas mazumtirgotāji, kas darbojas Latvijas tirgū. Pētījuma rezultāti tika apkopoti un analizēti, izmantojot nejaušas izlases metodi materiāla atlasei un strukturālās analīzes metodi, kas ļāva šī darba autoram veikt secinājumus, kas pierādīja, ka stilistiskie līdzekļi tiek plaši iz…
Elliptical Fourier Descriptors for shape retrieval in biological images
2002
The retrieval of information in a standard database can be obtained in different ways and in some cases a number of steps are necessary to extract the sought for information. More difficulties exist when we are looking for a pictorial information in a database. This paper presents a method for finding an image in a biological database based on elliptical Fourier descriptors. Fourier descriptors are considered here as textual information and a distance function is proposed to evaluate the best result. Fourier descriptors and distance function are used to retrieve image in pictorial database.
Second-order diagnostics for space-time point processes with application to seismic events
2008
A diagnostic method for space-time point process is introduced and used to interpret and assess the goodness of fit of particular models to real data such as the seismic ones. The proposed method is founded on the definition of a weighted process and allows to detect second-order features of data, like long-range dependence and fractal behavior, that are not accounted for by the fitted model. Applications to earthquake data are provided. Copyright © 2008 John Wiley & Sons, Ltd.
Heterogeneous Photocatalysis for Selective Formation of High-Value-Added Molecules: Some Chemical and Engineering Aspects
2018
This review deals with the parameters that influence heterogeneous photocatalysis (PC) for selective synthesis of high-value chemicals by itself or in combination with other technologies. In particular, the parameters related to the photocatalysts, such as crystallinity degree, type of polymorph, surface acid-base properties, exposure of particular crystalline facets, coupling of different semiconductors, position of the valence and conduction band edge, addition of doping agents, and those related to the reaction system, such as setup configuration and reactor geometry, type of solvent, type and amount of photocatalyst, affecting the selectivity toward specific products are described and d…
Assessment of paradoxical anterior translation in a CR total knee prosthesis coupling dynamic RSA and FE techniques
2021
Purpose: The study aims were to assess the kinematic data, Internal-External (IE) rotation, and Antero-Posterior (AP) translation of the contact points between the femoral condyles and polyethylene insert and to develop a combined dynamic RSA-FE (Radiostereometric – Finite Element) model that gives results congruent with the literature. Methods: A cohort of 15 patients who underwent cemented cruciate-retaining highly congruent mobile-bearing total knee arthroplasty were analyzed during a sit-to-stand motor task. The kinematical data from Dynamic RSA were used as input for a patient-specific FE model to calculate condylar contact points between the femoral component and polyethylene insert. …
Enterococcal meningitis caused by Enterococcus casseliflavus. First case report
2005
Abstract Background Enterococcal meningitis is an uncommon disease usually caused by Enterococcus faecalis and Enterococcus faecium and is associated with a high mortality rate. Enterococcus casseliflavus has been implicated in a wide variety of infections in humans, but never in meningitis. Case presentation A 77-year-old Italian female presented for evaluation of fever, stupor, diarrhea and vomiting of 3 days duration. There was no history of head injury nor of previous surgical procedures. She had been suffering from rheumatoid arthritis for 30 years, for which she was being treated with steroids and methotrexate. On admission, she was febrile, alert but not oriented to time and place. H…
Darba sludinājumu reģistra analīze
2016
Šī bakalaura darba pētījuma mērķis bija veikt lingvistisko analīzi korpusam, kas sastāvēja no 20 darba sludinājumiem, lai noteiktu lingvistikās iezīmes, kuras raksturo reģistru un palīdz sasniegt tā komunikatīvos mērķus. Bakalaura darba autore veica šo analīzi, izmantojot Baibera un Konrāda (2009) sarakstu ar lingvistikas iezīmēm. Pētījuma rezultāti parādīja, ka pašas izplatītākās iezīmes ir pirmās un otrās personas vietniekvārdi, īpašvārdi, kuri norāda uz valodām,uzņēmumu nosaukumiem, atvasināti un pamata formas īpašības vārdi, vairāku vārdu leksiskie darbības vārdi. Komunikatīvais mērķis - informēt kandidātu, tiek sasniegts ar abreviatūru un modālo un darbības vārdu, lietvārdu lietošanu,b…
Stationary phase modulation in liquid chromatography through the serial coupling of columns: A review
2016
Liquid chromatography with single columns often does not succeed in the analysis of complex samples, in terms of resolution and analysis time. A relatively simple solution to enhance chromatographic resolution is the modulation of the stationary phase through the serial coupling of columns. This can be implemented with any type of column using compatible elution conditions and conventional instruments. This review describes the key features of column coupling and published procedures, where two or more columns were coupled in series to solve separation problems. In all reports, the authors could not resolve their samples with single columns, whereas significant enhancement in chromatographi…
Heterozygous HMGB1 loss-of-function variants are associated with developmental delay and microcephaly
2021
International audience; 13q12.3 microdeletion syndrome is a rare cause of syndromic intellectual disability. Identification and genetic characterization of patients with 13q12.3 microdeletion syndrome continues to expand the phenotypic spectrum associated with it. Previous studies identified four genes within the approximately 300 Kb minimal critical region including two candidate protein coding genes: KATNAL1 and HMGB1. To date, no patients carrying a sequence-level variant or a single gene deletion in HMGB1 or KATNAL1 have been described. Here we report six patients with loss-of-function variants involving HMGB1 and who had phenotypic features similar to the previously described 13q12.3 m…
Light availability and land‐use history drive biodiversity and functional changes in forest herb layer communities
2020
International audience; A central challenge of today's ecological research is predicting how ecosystems will develop under future global change. Accurate predictions are complicated by (a) simultaneous effects of different drivers, such as climate change, nitrogen deposition and management changes; and (b) legacy effects from previous land use. We tested whether herb layer biodiversity (i.e. richness, Shannon diversity and evenness) and functional (i.e. herb cover, specific leaf area [SLA] and plant height) responses to environmental change drivers depended on land-use history. We used resurvey data from 192 plots across nineteen European temperate forest regions, with large spatial variabi…
