2020

Bakalaura darba tēma ir „Uzņēmuma Greenvalley mārketinga aktivitātes no 2016. līdz 2019.gadam”. Uzņēmums Greenvalley regulāri veic komunikāciju ar saviem klientiem izmantojot sociālās platformas – Facebook, Instagram, LinkedIn. Sociālajos tīklos tiek ievietotas publikācijas par aktuālajām tēmām, kas saistītas ar agro kultūras un dārzniecības nozarēm. Kā arī tiek sniegti praktiski padomi par dārzniecību un tās darbībām mājas apstākļos. Bakalaura darba mērķis ir noskaidrot kādas mārketinga aktivitātes veic uzņēmums Greenvalley, kā arī kāds ir uzņēmuma klientu un sociālo tīklu sekotāju viedoklis par uzņēmuma komunikāciju. Darba teorētiskā daļa sastāv no četrām nodaļām un sešām apakšnodaļām, ku…

One-pot synthesis of PbS NP/sulfur-oleylamine copolymer nanocomposites via the copolymerization of elemental sulfur with oleylamine

2014

A novel synthetic and processing strategy for converting elemental sulfur into polymeric and nanocomposite materials is reported. We describe a facile one-pot reaction using elemental sulfur and oleylamine as comonomers to prepare high sulfur content copolymers and lead sulfide nanoparticle (PbS NP) nanocomposites. This process enables the preparation of solution processable copolymers and nanocomposites, where the loading and dispersion of PbS NP inclusions could be precisely controlled. We demonstrate the dual roles of oleylamine with sulfur for both the copolymerization of sulfur copolymers as well as the in situ synthesis of PbS NPs in a one-pot fashion.

De la ley de barrios al diseño de políticas locales de empleo

2009

(Erm) de Manlleu, localidad de la provincia de Barcelona. La investigación forma parte de un conjunto de acciones integradas llevadas a cabo en el Erm a partir de la aplicación de la denominada Ley de Barrios, impulsada por el Gobierno catalán. La Ley facilita el desarrollo de actuaciones en el ámbito local, especialmente en el terreno urbanístico. Pero, como mostraremos, puede ser también un instrumento eficaz para desarrollar políticas de promoción del empleo ligadas al territorio. Un tipo de políticas que remite a la importancia que viene adquiriendo el ámbito local en cuestiones de empleo; y que se refleja en los numerosos estudios que se realizan en torno a la idea del desarrollo local…

The effect of intracavernosal growth differentiation factor-5 therapy in a rat model of cavernosal nerve injury.

2006

OBJECTIVE To determine whether the intracavernosal application of growth differentiation factor-5 (GDF-5) influences nerve regeneration and erectile function after cavernosal nerve injury in a rat model. MATERIALS AND METHODS Thirty-two male Sprague-Dawley rats were randomly divided into four equal groups: eight had a sham operation (uninjured controls), while 24 had bilateral cavernosal nerve crush. The crush-injury groups were treated at the time of injury with an impregnated collagen sponge implanted into the right corpus cavernosum. The sponge contained no GDF-5 (injured controls), 2 µg (low concentration), or 20 µg GDF-5 (high concentration). Erectile function was assessed by cavernosa…

Endogenous and exogenous nitric oxide inhibits norepinephrine release from rat heart sympathetic nerves.

1995

Abstract This study was designed to elucidate whether nitric oxide (NO) controls norepinephrine (NE) release from sympathetic nerves of the rat heart. Hearts were perfused in the Langendorff mode with Tyrode’s solution. The right sympathetic nerve was stimulated with trains of 1 or 3 Hz and NE release was measured. The NO synthase (NOS) inhibitor N G -nitro- l -arginine (L-NNA) enhanced the evoked NE release in a concentration-dependent manner. This facilitation was independent of the increase in perfusion pressure and was stereospecifically reversed by l -arginine but not d -arginine. Another NOS inhibitor, N G -methyl- l -arginine, produced a similar increase in NE release. The NO-donor …

Regular theta-firing neurons in the nucleus incertus during sustained hippocampal activation

2015

This paper describes the existence of theta-coupled neuronal activity in the nucleus incertus (NI). Theta rhythm is relevant for cognitive processes such as spatial navigation and memory processing, and can be recorded in a number of structures related to the hippocampal activation including the NI. Strong evidence supports the role of this tegmental nucleus in neural circuits integrating behavioural activation with the hippocampal theta rhythm. Theta oscillations have been recorded in the local field potential of the NI, highly coupled to the hippocampal waves, although no rhythmical activity has been reported in neurons of this nucleus. The present work analyses the neuronal activity in t…

Co-expression of heat sensitive vanilloid receptor subtypes in rat dorsal root ganglion neurons

2003

Expression of the heat sensitive cation channels TRPV1 and TRPV2 was investigated by immunofluorescence in rat dorsal root ganglion (DRG) neurons. TRPV1-positive neurons were more frequent and had smaller diameters than TRPV2-positive neurons (35.7% vs 7.3%; 22.3 microm vs 27.6 microm), but size distributions overlapped and significant co-expression was seen in 20.7% of TRPV2-positive neurons (1.7% of all). Expression patterns did not differ between tissue sections typically used in immunocytochemistry and dissociated DRG neurons typically used in electrophysiology. Rectangular temperature pulses revealed two patterns of heat-evoked inward currents in small DRG neurons: low-threshold rapidl…

On two topological cardinal invariants of an order-theoretic flavour

2012

Noetherian type and Noetherian $\pi$-type are two cardinal functions which were introduced by Peregudov in 1997, capturing some properties studied earlier by the Russian School. Their behavior has been shown to be akin to that of the \emph{cellularity}, that is the supremum of the sizes of pairwise disjoint non-empty open sets in a topological space. Building on that analogy, we study the Noetherian $\pi$-type of $\kappa$-Suslin Lines, and we are able to determine it for every $\kappa$ up to the first singular cardinal. We then prove a consequence of Chang's Conjecture for $\aleph_\omega$ regarding the Noetherian type of countably supported box products which generalizes a result of Lajos S…

Generalizations of the periodicity Theorem of Fine and Wilf

2005

We provide three generalizations to the two-dimensional case of the well known periodicity theorem by Fine and Wilf [4] for strings (the one-dimensional case). The first and the second generalizations can be further extended to hold in the more general setting of Cayley graphs of groups. Weak forms of two of our results have been developed for the design of efficient algorithms for two-dimensional pattern matching [2, 3, 6].
