Stimulation of synovial fluid mononuclear cells with the human 65-kD heat shock protein or with live enterobacteria leads to preferential expansion o…

1992

SUMMARY T lymphocyte responses to heterologous or self 65-kD heat shock protein (hsp) have been implicated in the pathogenesis of various forms of arthritis. To delineate the relationship of 65-kD hsp to different synovial fluid (SF) T cell subsets, we stimulated synovial fluid (SFMC) and peripheral blood mononuclear cells (PBMC) from patients with different inflammatory rheumatic diseases and from healthy controls with human or mycobacterial 65-kD hsp, tetanus toxoid (TT), heat-killed or live Yersinia enterocotitica. Phenotyping of the resulting T cell lines revealed an increase of up to 97% TCR-γδ+ lymphocytes in the 65-kD hsp-stimulatcd SF-derived lines. This expansion of TCR-γδ+ cells w…

Den kultur- och litteraturhistoriska gestalten i den lettiska novellen “Svētā Briģita” (“Heliga Birgitta”) av Jānis Ezeriņš

2019

Cultural-historical and literary gestalt in the Latvian short story “Saint Birgitta” (“Heliga Birgitta”) by Jānis EzeriņšThe Latvian author Jānis Ezeriņš’s (1891–1924) literary heritage includes, among other texts, the collection of short stories Fantastiska novele un citas (Fantastic short story and others, 1923). The collection contains the short story “Svētā Briģita” (“Saint Birgitta”), in which the author has used the image of a saint, which is very well known in the history of culture, literature and religion. The image can be related both to Celtic mythology and the historical Swedish personality, who had been the founder of Vadstena monastery and a literary author herself (approx. 13…

Pirmsskolas vecuma bērnu patstāvības veicināšana celtniecības rotaļās

2018

Darba autore: Inga Branca Darba nosaukums: “Pirmsskolas vecuma bērnu patstāvības veicināšana celtniecības rotaļās” Darba mērķis: Izzināt pirmsskolas vecuma bērnu patstāvības sekmēšanu celtniecības rotaļās Pētījuma mērķis ir izzināt pirmsskolas bērnu patstāvības sekmēšanu celtniecības rotaļās. Pirmajā nodaļā tiks analizētas pedagogu un psihologu teorijas un atziņas par celtniecības rotaļām un to kā sekmēt bērna patstāvību šajās rotaļās. Šajā nodaļā uzzināsim, kas ir patstāvība un kas nepieciešams, lai to attīstu. Tika izvirzīta hipotēze, ka bērnu patstāvības veidošanās celtniecības rotaļā būs veiksmīga, ja bērnam ir brīvi pieejama vieta, materiāli un laiks rotaļai savas ieceres izstrādei. La…

Variational approach to the mechanics of metal V-belt systems

2005

The mechanical behaviour of metal V-belt drives is strongly dependent on the elastic properties of both the belt and the pulley, which influence the belt penetration into the groove and the sliding on the pulley wall. The distribution of tension and penetration is quite different from the rubber belts, which may be dealt with in the assumption of perfectly rigid pulleys. The restoring effect of the centrifugal forces of the plate elements has also to be taken into account. The present analysis considers the combination of all those effects, choosing a three parameter deformation function to describe the plate bending and applying the principle of virtual work for the calculation of the unkn…

Centrālo banku rezervju politika: Monetārais zelts

2019

Monetārais zelts pasaules Centrālo Banku rezervju struktūrā ir tikai vēsturiskais mantojums, vai arī gadiem pārbaudīts aktīvs? Darba autors cenšas rast atbildi uz doto jautājumu sava pētījuma gaitā. Neskatoties uz tik dažādiem uzskatiem un Centrālo banku īstenojamām rezervju pārvaldīšanas politikām, monetārais zelts ik reizi atdzimst kā fēnikss no pelniem, pasaules ekonomikai un ģeopolitikai piedzīvojot satricinājumu. Maģistra darba mērķis- pamatojoties uz pasaules aktīvāko centrālo banku īstenojamām rezervju politikām, izpētīt zelta rezervju īpatsvara izmaiņu ietekmējošos faktorus, izanalizēt tendences un aktualitātes, izdarīt secinājumus un sniegt priekšlikumus Centrālo Banku vadībai.

Die Kristallisation von Mehrkomponentensystemen aus hochpolymeren Stoffen

1977

Es wird untersucht, welche Anderungen im Kristallisationsverhalten hochpolymerer Stoffe auftreten, wenn man von einem Einkomponentensystem auf ein Mehrkomponentensystem ubergeht. Beispiele fur Mehrkomponentensysteme sind Homopolymere mit einer breiten Molekulargewichtsverteilung, Mischungen aus verschiedenen Homopolymeren, gequollene Polymere, Blockcopolymere und statistische Copolymere. Das Auftreten einer Molekulargewichtsverteilung ausert sich vor allem bei einer Kristallisation mit gestreckten Ketten, und zwar in der Weise, das eine Fraktionierung nach Molekullangen auftritt. Des weiteren bewirkt sie eine Verbreiterung des Schmelzbereichs. Die Anwesenheit eines zweiten nichtkristallisie…

Immunotherapy With Human Gamma Delta T Cells—Synergistic Potential of Epigenetic Drugs?

2018

Epigenetics has emerged as one of the fastest growing concepts, adding more than 45 new publications every day, spreading through various fields ( 1). Conrad Waddington coined the term “epigenetics” in 1942; however, a multitude of definitions has been endorsed by different researchers. In essence, Waddington’s definition of “epigenetics” and its redefinition by Holiday is at the heart of cellular function. Hence, it is obvious that epigenetic regulation plays a central role also in the specification, differentiation, and functional plasticity of T lymphocytes ( 2). T-cell fate decision in progenitor cells, functional CD4 T-cell plasticity, CD8 T-cell differentiation, but also T-cell memory…

A vacuum cell for obtaining clean surfaces on liquid low melting point metals

1997

Abstract Clean oxide film-free surface of liquid gallium was obtained in a sealed vacuum cell with a glass lid for observation. The cell was evacuated to high vacuum (10 -4 Pa) before admission of liquid and sealing. The surface contamination was about 2–5% of the free area and did not exhibit noticeable increase during several months of storing and employing the cell. The cell described allows observation of surface flows, capillary phenomena and crystallization processes under different conditions.

Crystal and molecular structure of anhydrous betaine, (CH3)3NCH2CO2

1999

Abstract 1–Carboxy–N,N,N–trimethylmethanamanium inner salt or anhydrous betaine, (CH3)3NCH2CO2, FW=117.15 gmol −1 , crystallizes in the orthorhombic space group Pnma with a=14.544(2) A , b=6.859(3) A , c=6.131(1) A , V=611.7(3) A 3 , Z=4, D x =1.27 Mgm −3 , λ (MoK α )=0.71073 A , μ =0.091 mm −1 . The structure was resolved by direct methods and refined by least-square calculations to R=0.038 for 531 reflections. Observed changes in bond angles imply that there is a repulsion between nitrogen and oxygen. The melting point (measured at onset) is 570 K. FTIR spectra of anhydrous betaine and monohydrate were recorded. Clear differences were found between the two compounds based on infrared (i.r…
