Identification and quantification of phosphatidylcholines containing very long chain polyunsaturated fatty acid (VLC-PUFA) in bovine and human retina…
2010
The retina is one of the vertebrate tissues with the highest content in polyunsaturated fatty acids (PUFA). A large proportion of the retinal glycerophospholipids, especially those found in photoreceptor membranes, are dipolyunsaturated molecular species. Among them, dipolyunsaturated phosphatidylcholine molecular species are known to contain very long chain polyunsaturated fatty acids (VLC-PUFA) from the n-3 and n-6 series and having 24 to 36 carbon atoms (C24 to C36) and four to six double bonds. Recent interest in the role of VLC-PUFA arose from the findings that a protein named ELOngation of Very Long chain fatty acids 4 (ELOVL4) is involved in their biosynthesis and that mutations in E…
Mantas konfiskācija kā kriminālsods, tās norobežošanā no mantas īpašas konfiskācijas
2018
Bakalaura darba „Mantas konfiskācija kā kriminālsods, tās norobežošanā, no mantas īpašas konfiskācijas" autors, aplūkojot dažādus literatūras avotus, analizēja mantas konfiskācijas kā soda un mantas īpašas konfiskācijas piemērošanas tendences, savstarpējās atšķirības, regulējuma attīstību. Mantas konfiskācija kā sods atšķiras no mantas īpašās konfiskācijas, katram no šiem institūtiem ir sava piemērošanas joma, kas ir savstarpēji jānorobežo viens no otra. Ar 2017.gada 22.jūnija grozījumiem Krimināllikums tika papildināts ar VIII2 nodaļu "Mantas īpašā konfiskācija", kas ir pareizi, jo iepriekš šis jautājums tika regulēts Kriminālprocesa likumā, tomēr salīdzinot Krimināllikumā ietverto regulēj…
Predicting tire/pavement noise impact reduction using numerical simulation and experimental data for open graded asphalt mixture
2013
The environmental impact of noise from roads and highways traffic is relevant in urban and rural areas. The use of open-graded asphalt pavements reduces significantly the noise, entrapping the acoustic waves inside the porous structure of the material. In this paper we propose a simulation approach in order to predict the acoustic properties of the asphalt mixture from geometrical and topological indicators. In detail we have generated, using a Random Sequential Adsorption model, synthetic samples starting from the same grading and bitumen contents of real samples manufactured in laboratory. We have measured the acoustic adsorption coefficient of the real samples and we have investigated th…
Recent progress in metal-organic frameworks (MOFs) for CO2 capture at different pressures
2022
Global climate change ensued by the rise in atmospheric CO2 levels is one of the greatest challenges our planet is facing today. This worldwide distress demands technologies that can contribute to our society toward “negative carbon emissions”. Carbon capture and storage (CCS) technologies are in in important role for capturing CO2 from existing emission sources, such as industrial and energy production point sources, before new more prominent modifications to the energy infrastructure can be implemented. Recently, alongside point source capture, direct air capture (DAC) processes have emerged as highly sought-after technologies that are able to capture CO2 from the ambient air. Alongside t…
Influence of PDA Coating on the Structural, Optical and Surface Properties of ZnO Nanostructures
2020
Polydopamine (PDA) is a new biocompatible material, which has prospects in biomedical and sensor applications. Due to functional groups, it can host wide range of biomolecules. ZnO nanostructures are well known templates for optical sensors and biosensors. The combination of ZnO and PDA results in a change of optical properties of ZnO&ndash
Kriminālsods - probācijas uzraudzība
2020
Bakalaura darba “Kriminālsods–probācijas uzraudzība” mērķis - izpētīt un noskaidrot probācijas uzraudzības attīstību pētot normatīvos aktus, tiesu praksi, un salīdzināt iegūtos rezultātus ar ārvalstīm. Probācijas uzraudzība Krimināllikumā tika ietverta 2011.gada 1.oktobrī par noziedzīgiem nodarījumiem pret tikumību un dzimumneaizskaramību, sakot no 2015.gada 1.janvāra par citiem Krimināllikuma Sevišķajā daļā paredzētajiem noziedzīgiem nodarījumiem. Bakalaura darbā ir norādīti vairāki problēmjautājumi un ietverti to iespējamie risinājumi, piemēram, Latvijas Sodu izpildes kodeksa divdesmit ceturtās “A” nodaļas papildināšana ar regulējumu, kas paredz pienākumu ārstēties no atkarībām probācijas…
Probācijas uzraudzība kā papildsods
2019
Probācijas uzraudzība kā papildsods ir salīdzinoši jauns tiesību institūts, kas Latvijas tiesību sistēmā parādījās tikai 2011. gada 1. oktobrī, kad to sākotnēji varēja piemērot personām par izdarītajiem noziedzīgiem nodarījumiem pret tikumību un dzimumneaizskaramību. Taču pilnībā probācijas uzraudzība kā papildsods stājās spēkā vien 2015. gada 1. janvārī, kura uzraudzību un izpildi nodrošina Valsts probācijas dienests. Bakalaura darbs “Probācijas uzraudzība kā papildsods” ir šī tiesību institūta izveidošanās apskats no policijas kontroles institūta, iezīmējot tā piemērošanas problēmjautājumus, kas radušies normatīvo aktu nepārtraukta pilnveidojuma rezultātā. Pētījuma mērķis ir ne tikai apsk…
Antibacterial Efficiency of Surface-Immobilized Flavobacterium-Infecting Bacteriophage
2019
Control of bacterial diseases by bacteriophages (phages) is gaining more interest due to increasing antibiotic resistance. This has led to technologies to attach phages on surfaces to form a biomaterial that can functionally display phages that interact with bacteria, to carry out successful infection cycles. Such a material could be applied in many environments, where the target pathogens are expected. Although this approach has been applied successfully in a few studies already, the basis of the antibacterial effect by the immobilized phages is unclear, and the interpretation of the results depends on the study. Here, we studied the phage attachment density, their detachment rate and infe…
Heterogeneous photocatalytic degradation of pharmaceuticals in water by using polycrystalline TiO2 and a nanofiltration membrane reactor
2006
Abstract A study of the photodegradation of different pharmaceuticals [furosemide, ranitidine (hydrochloride), ofloxacine, phenazone, naproxen, carbamazepine and clofibric acid] in aqueous medium at various pHs by using a batch photoreactor and a photocatalytic membrane reactor working in recirculation regime was carried out. Polycrystalline TiO 2 was used as the photocatalyst, and different membranes (NTR 7410, PAN GKSS HV3/T, N 30 F, NF PES 10) were tested. A different adsorption of the substrates onto the catalyst surface was observed owing to the hydrophilic/hydrophobic character of the catalyst, depending on the pH. The photodegradation of the seven molecules in the batch reactor was s…
Plasma polymer films and gold nanoparticles: coupling of properties to design a biosensor
The present investigation deals with the functionalization of gold nanoparticles (Au NPs) with primary amine-based plasma polymer films (NH2-PPF), to improve their properties for bioanalytical applications. Cyclopropylamine (CPA) plasma polymerization, in pulsed and continuous wave radio frequency discharges, was employed to growth CPA amino-based PPFs coatings (18 nm) onto Au NPs of 12 nm of diameter deposited on glass and silicon substrates. A multi-technique investigation, based on FT-IR and XPS spectroscopies, AFM and SEM microscopies and Tof-SIMS spectrometry, revealed peculiar features of the CPA PPFs. In particular, by FT-IR it was possible to obtain an overview about the rich chemis…
