Reklāma kā tēma kulturoloģijā
2019
Diplomdarba tēma - Reklāma kā tēma kulturoloģijā. Pētījuma ievadā pamatota temata izvēle un aktualitāte, kas balstās uz jauniešu izglītošanu par reklāmas būtību un tās lomu sabiedrības vērtību sistēmas ietekmēšanā, uzskatu veidošanā. Darbā izpētīta teorētiskā informācijas bāze par reklāmu. Izpētītas un sistematizētas reklāmas definīcijas, mērķi, veidi un uzdevumi, aplūkota reklāmas vēsturiskā attīstība no pirmsākumiem līdz tās jaunajai realitātei digitālajā laikmetā, sniegts ieskats reklāmas ētikā, aplūkojot tās lomu mūsdienu patērējtājsabiedrībā, apskatīti svarīgākie reklāmas psiholoģijas aspekti un to ietekme uz sabiedrības un indivīda apziņu. Pētījumā apzināti reklāmas izpētes un veidoša…

User charges for education : the ability ans willingness to pay in Malawi
1984
Investment in education is generally recognized to be essential for a country's long-term economic and social development. However, presentmacroeconomic conditions in many developing countries have obliged their governments to slow down increases in the allocation of public resources for education. As a result, the education sector is likely to develop only slowly, if at all; enrollment, already low in the poorer of the developing countries, would remain low, while the social demand for education would continue to be substantially unmet. In this setting, policy makers have recently focussed their attention on finding alternative sources of finance for education, one of which is the tapping …
Differential cysteine depletion in respiratory chain complexes enables the distinction of longevity from aerobicity.
2010
Mitochondrially encoded proteins in long-lived animals exhibit a characteristic anomaly on the amino acid usage level: they abstain from the use of cysteine in a lifespan-dependent fashion. Here, we have further investigated this phenomenon by analyzing respiratory chain complex subunits individually. We find that complex I cysteine depletion is the almost exclusive carrier of the cysteine-lifespan correlation, whereas complex IV cysteine depletion is uniform in all aerobic animals, unrelated to longevity, but even more pronounced than complex I cysteine depletion in the longest-lived species. In nuclear encoded subunits of the respiratory chain, we find lifespan-independent cysteine deplet…
Homodimeric murine interleukin-3 agonists indicate that ligand dimerization is important for high-affinity receptor complex formation.
1994
Homodimeric murine interleukin 3 (mIL-3) agonists were generated by intermolecular cystine-bonding. Steady-state binding assays and association kinetics performed at 4 degrees C using these agonists revealed specific binding to both the high- and low-affinity receptor. DSS-mediated crosslinking studies performed at 4 degrees C with agonist concentrations compatible with high-affinity receptor complex formation allowed to detect protein complexes of the alpha chain, the beta chain(s) and the high-affinity receptor complex migrating with apparent molecular weights of 90 kDa, 140 kDa, and above 180 kDa, respectively. In contrast, monomeric mIL-3 was crosslinked to the alpha chain receptor only…
Extracellular Domains of the Bradykinin B2 Receptor Involved in Ligand Binding and Agonist Sensing Defined by Anti-peptide Antibodies
1996
Many of the physiological functions of bradykinin are mediated via the B2 receptor. Little is known about binding sites for bradykinin on the receptor. Therefore, antisera against peptides derived from the putative extracellular domains of the B2 receptor were raised. The antibodies strongly reacted with their corresponding antigens and cross-reacted both with the denatured and the native B2 receptor. Affinity-purified antibodies to the various extracellular domains were used to probe the contact sites between the receptor and its agonist, bradykinin or its antagonist HOE140. Antibodies to extracellular domain 3 (second loop) efficiently interfered, in a concentration-dependent manner, with…
Propagation of Calendula maritima Guss. (Asteraceae) through Biotechnological Techniques for Possible Usage in Phytotherapy
2022
The genus Calendula (Asteraceae) includes several species that are renowned for their therapeutic properties and/or use as ingredients in the preparation of cosmetics. The rare and critically endangered sea marigold, Calendula maritima Guss., an endemic species from Western Sicily, has also been recognized as a potential “farm plant species” for several important compounds used in cosmetics. However, the few remnant populations of this species are currently threatened with extinction because of several factors, such as hybridization with the congeneric species Calendula suffruticosa subsp. fulgida (Raf.) Guadagno and anthropogenic disturbance of its habitat. Therefore, in order to preserve …
Aleksander Kamiński - pedagog walki o niepodległość w latach drugiej wojny światowej
2018
Artykuł przedstawia osobę i działalność Aleksandra Kamińskiego w okresie drugiej wojny światowej. Podstawą opisu są wspomnienia jego córki i bliskich współpracowników. Doświadczenia w pracy harcerskiej przygotowały go wyzwań, które przyniosła drugiej wojna światowa. Kamiński był bardzo zaangażowany w budowę wojennych struktur harcerskich i działalność konspiracyjną. Ważną działalnością jego było redagowanie „Biuletynu Informacyjnego” Armii Krajowej oraz pisarstwo, które podkreślało realność walki z niemieckim okupantem. Wychowanie do dzielności, służba i pomoc innym były podstawą jego systemu wartości oraz wychowania
Rank two aCM bundles on the del Pezzo fourfold of degree 6 and its general hyperplane section
2018
International audience; In the present paper we completely classify locally free sheaves of rank 2 with vanishing intermediate cohomology modules on the image of the Segre embedding $\mathbb{P}^2$ x $\mathbb{P}^2 \subseteq \mathbb{P}^8$ and its general hyperplane sections.Such a classification extends similar already known results regarding del Pezzo varieties with Picard numbers 1 and 3 and dimension at least 3.
All-Optical frequency Shifter in a Periodically Poled Lithium Tantalate Waveguide
2011
A frequency shifting device is fabricated and tested in a congruent Lithium Tantalate waveguide. Periodic poling for quasi-phase-matching and channels for operation in the near-infrared C-band were obtained, demonstrating a two-stage parametric conversion.
