The pea sulfate transporter, PsSULTR4, contributes to seed yield and quality
2023
To investigate the role of vacuolar sulfate in seed yield and quality, we have targeted the single pea SULTR4 gene (PsSULTR4), which encodes a transporter homologous to Arabidopsis SULTR4;1 and 4;2 that allow sulfate efflux from the vacuole to the cytosol. By simulating the 3D structure of PsSULTR4, we observed that it is similar to that of SULTR4;1 in Arabidopsis. Furthermore, a phylogenetic analysis revealed a high level of conservation of SULTR4 protein motifs across land species. A fluorescent protein fusion experiment confirmed that PsSULTR4 localizes to the vacuolar membrane.Five sultr4 mutants were identified by TILLING (Targeting Induced Local Lesions IN Genomes), two of which showe…
Tehnoloģiju attīstības ietekme uz vadīšanas efektivitāti komercbankā.
2018
Darba ietvaros pētāmā problēma ir AS LPB Bank izmantotās lietvedības sistēmas ieviešanas procesa nepilnīga izpilde, kā arī tendence pārāk lēni ieviest jauno tehnoloģiju risinājumus AS LPB Bank ikdienas darbībā. Darba mērķis ir, pamatojoties uz AS LPB Bank darbības un ikdienas procesu analīzi, identificēt galvenās problēmas AS LPB Bank, kas radušās no ieviestās sistēmas un izstrādāt priekšlikumus šo problēmu atrisināšanai. Darbā iegūtie rezultāti ir konkrētu priekšlikumu izstrāde, lai novērstu kā esošās, tā potenciālās problēmas ar ieviesto sistēmu nākotnē, kā arī veicinātu vispārēju AS LPB Bank attīstību IT virzienā. Darbs sastāv no ievada, 4 nodaļām, secinājumiem, priekšlikumiem un izmanto…
Nestandartu interneta vārdnīcu struktūra
2015
Spēja noteikt strukturālos elementus, kuri ir nepieciešami vārdnīca ssastādīšanai, ir būtiska leksikogrāfa prasme. Maģistra darba mērķis ir izanalizēt nestandarta vārdnīcas autoru un atbalstītāju strukturālās izvēles, kuras ir izmantotas individuālo projektu vārdnīcu saradīšanai. Mērķa sasniegšanai izmantotās metodes ir literatūras apraksts, lai formulētu teorētisko bāzi, un manuāla datu vākšana un aprakstoša analīze. Analīzes rezultāti atļāva identificēt defektus izvēlētajos struktūras elementos un apsvērt defektu ietekmi uz vispārējo vārdnīcas kvalitāti. Tomēr rezultāti arī liecināja, ka, neskatoties uz kļūdām, vārdnīcu autoriem ir dažas atkārtojošās izvēles struktūru organizācijā, lai ga…
Modeling of Friction Losses in Offshore Knuckle Boom Crane Winch System
2018
This paper presents a method for friction modeling in a hydraulically actuated multi motor winch system of an offshore knuckle boom crane. The method is based on a combination of a model of the variable displacement axial piston motor based on measurements from the sub supplier, and combined with a model of the remaining friction loss obtained from measurements on the full system.
Comparison of anterior cingulate vs. insular cortex as targets for real-time fMRI regulation during pain stimulation
2014
© 2014 Emmert Breimhorst Bauermann Birklein Van De Ville and Haller. Real time functional magnetic resonance imaging (rt fMRI) neurofeedback allows learning voluntary control over specific brain areas by means of operant conditioning and has been shown to decrease pain perception. To further increase the effect of rt fMRI neurofeedback on pain we directly compared two different target regions of the pain network notably the anterior insular cortex (AIC) and the anterior cingulate cortex (ACC). Participants for this prospective study were randomly assigned to two age matched groups of 14 participants each (7 females per group) for AIC and ACC feedback. First a functional localizer using bloc…
Random Vibrations of Structures under Propagating Excitations
1995
The problem of vibrations of structures under incoherent or, in particular, propagating excitations is important for large, extended civil engineering structures like bridges, lifelines, dams, offshore structures or for aircraft structures. In seismic engineering spatial ground motion models have been studied for more than a decade but credible, stochastic characteristics are available only since SMART-1 accelerograph array is in operation at Lotung in Taiwan.
Effects of fabrication on the mechanics, microstructure and micromechanical environment of small intestinal submucosa scaffolds for vascular tissue e…
2013
In small intestinal submucosa scaffolds for functional tissue engineering, the impact of scaffold fabrication parameters on success rate may be related to the mechanotransductory properties of the final microstructural organization of collagen fibers. We hypothesized that two fabrication parameters, 1) preservation (P) or removal (R) of a dense collagen layer present in SIS and 2) SIS in a final dehydrated (D) or hydrated (H) state, have an effect on scaffold void area, microstructural anisotropy (fiber alignment) and mechanical anisotropy (global mechanical compliance). We further integrated our experimental measurements in a constitutive model to explore final effects on the micromechanic…
The geographic information in the assessment of geohazard in the marine environment
2011
Slope instability and erosion, mass transport, volcanic and tectonic activity, fast sediment accumulation fluid escape are the main processes responsible for the geohazard in marine environment. A major knowledge about the geological setting of the offshore areas and related processes can be crucial to assess and manage the potential geological risks. High resolution morphobathymetric surveys, yielded in the frame of the MaGIC project (Marine Geohazards along the Italian Coasts), integrated with previously acquired data, single-channel seismic reflection profiles, backscatter data and sediments sampling, allow to define the geomorphological, stratigraphic and structural features in the offs…

Hsp60 in embryonic and adult submandibular salivary gland: quantitative distribution patterns in normal tissue and comparison with benign and maligna…
2019
Introduction: Heat Shock Protein 60 (Hsp60) is a member of the chaperoning system that assists protein folding inside mitochondria and plays other roles beyond these organelles. It is implicated in the carcinogenic processes in various types of cancer. In human salivary glands, Hsp60 has not yet been measured or mapped in detail and its role in gland development and functioning is virtually unknown. Consequently, its potential as biomarker for gland diseases, including malignancies cannot be assessed. The S-100 protein, a known marker for schwannomas, has been found also in myoepithelial-cell carcinomas of the salivary glands. Here, we present our initial findings on the anatomic-histologic…
