Estudio de las fluctuaciones del nivel del agua en la laguna de Gallocanta (Aragón, España) mediante imágenes satelitales de Sentinel-2
2021
[EN] This study has been monitored for five years by Sentinel-2 satellite images, at different seasons of the year, of the fluctuations in the water level of the Gallocanta Lake (between the provinces of Teruel and Zaragoza, Spain) considered a hypersaline and endorheic wetland, which has characteristics that make it unique in the geographical area in which it is located, as well as for the operation of the system. Rainfall in the area has a wide variation giving the maximums in the moths of May and June and the minimums in January and February, with considerable fluctuations in the water level from the almost total drying of the lagoon to the filling with a depth of approximately 3 meters.
Der Völkerfrühling von 1848/1849 – revolutionäre Gefahr oder republikanischer Durchbruch? Ästhetisch-historische Bilder
2022
The aim of this article is to present the revolutionary events of 1848/1849 in German states from the point of view of Joseph von Eichendorff and Theodor Opitz, which are based on their refl ections, experiences and reactions to this political and breakthrough coup. Eichendorff and Opitz present two different views on the events of the Spring of Nations. These two intellectuals and writers are linked by the last letter from Eichendorff to Theodor Opitz as well as the ideal of freedom, which became their life motto.
Alterations of Activities of Ribonucleases and Polyadenylate Polymerase in Synchronized Mouse L Cells
1977
The activities of the three known catabolic and the one anabolic polyadenylate enzymes have been determined in synchronized L5178y cells: endoribonuclease, exoribonuclease, 5'-nucleotidase and poly(A) polymerase (Mg2+-dependent). These four enzymes were found primarily in the nuclear fraction. The activity of poly(A) polymerase remains essentially constant during the transition from G1 to S phase. However, the poly(A) catabolic enzyme activities increase parallel with DNA synthesis; the endoribonuclease activity increases 4-fold during G1 to S phase, the exoribonuclease and the nucleotidase activities increasing 30-fold and 16-fold. During the S phase the poly(A)-degrading enzymes are far m…
Association of AUUUA-binding Protein with A + U-rich mRNA during nucleo-cytoplasmic transport
1992
Resealed nuclear envelope (NE) vesicles from rat liver containing entrapped exogenous RNA were used to study the effect of adenosine+uridine binding factor (AUBF), present in cytosolic cell extracts, on ATP-dependent transport of A+U-rich RNA (AU+RNA) and A+U-free RNA (AU-RNA) across the NE. This factor specifically binds to A+U-rich sequences present in the 3' untranslated regions of lymphokine and cytokine mRNAs, containing overlapping AUUUA boxes (granulocyte-macrophage colony stimulating factor, interleukin-3). Addition of AUBF to the extravesicular compartment markedly increased the efflux of the in vitro transcribed, capped and polyadenylated AU+ RNAs. Export of entrapped AU- control …
Kā slavenības ietekmēt patērētāju pirkšanas lēmumu?
2018
Mūsdienās slavenību ietekme ir ļoti ievērojama pasaules tirgus sastāvdaļa, kurā tiek ieguldīti miljoni. Viena no tendencēm mārketingā ir vietējo ekspertu, t.s. mikroslavenību, izmantošana produkta un pakalpojuma virzīšanā, kopā ar tradicionālām slavenībām, kuras ir pazīstamas visā pasaulē. Šīs maģistra darbs izpēta slavenību ietekmi, to efektu uz patērētāju pirkšanas uzvedību un patērētāju attieksmi pret slavenībām. Pētījumā izmantota kvalitatīva metoda sakarā ar to, ka tā atļauj dziļi izpētīt patērētāju uzskatus, viedokļus un komentārus. 24 dalībnieki no 150 piekrita piedalīties pētījumā. Tie tika sadalīti četrās fokusa grupās. Dalībnieki no 17 valstīm, to vecums ir 18-35 gadi, tiem ir Ins…
Market Polarization due to Difference in Interface Implementation Efforts
2009
Another factor potentially affecting the evolution of the OSS/BSS software market is the high complexity of software interfaces. The software provided to a customer – a CSP – needs to be integrated with a number of heterogeneous subsystems deployed by the customer. If the number of integration interfaces is high, a vast amount of special knowledge is needed in the vendor organization. High integration efforts also take up the time of the compentent employees of the vendor organization, thereby reducing the number of customers which it is capable of serving. As a result, only few large vendors can compete in such market, and, due to a lack of competition, the evolution towards a horizontaliz…

The underlying processes governing seed size plasticity: Impact of endoploidy on seed coat development and cell expansion in Medicago truncatula
2019
Prod 2019-55a BAP GEAPSI CT1 BAP; Abstract Bigger seeds represent an agronomic and economic benefit but the breeding and ecological balance between seed size and number is difficult to find. Large seeds associated with other practices can improve crop competitiveness as they are more vigorous and result in healthier crops with higher yields, even under stressful conditions. Applying genomic research and genome-wide association studies to breeding is generating new strategies to improve seed traits and novel insights into the biology of seed development and metabolism that are discussed in this chapter. The DNA amount differs among the seed tissues and amplifying genomic DNA by endocycle ind…
Endoreduplication induced in cultured Chinese hamster cells by different anti-topoisomerase II chemicals
2005
With the ultimate purpose of testing the hypothesis that, as shown in yeast mutants, any malfunction of DNA topoisomerase II might result in aberrant mitosis due to defective chromosome segregation, we have chosen three chemicals of different nature, recently reported to catalytically inhibit the enzyme. The endpoint selected to assess any negative effect on the ability of topoisomerase II to properly carry out decatenation of fully replicated chromosomes in the G2/M phase of the cell cycle was the presence of metaphases showing diplochromosomes as a result of endoreduplication, i.e. two successive rounds of DNA replication without intervening mitosis. The anti-topoisomerase drugs selected …
Modulation of Nuclear Matrix-associated 2′,5′-Oligoadenylate Metabolism and Ribonuclease L Activity in H9 Cells by Human Immunodeficiency Virus
1989
Human T cells (H9), infected with the HTLV-IIIB strain of the human immunodeficiency virus (HIV-1), have been used to study the alteration of 2',5'-oligoadenylate [2'-5')A) metabolism in relation to virus production. The synthesis of (2'-5')A was determined to proceed in close association with the nuclear matrix. After HIV infection the (2'-5')A synthetase activity increased from 1.1 to 1.5 pmol of (2'-5')A synthesized/100 micrograms of nuclear matrix protein (during a 3-h in vitro incubation period) to 8.2 pmol at day 3 after infection. Then the activity dropped to the initial values. In non-infected H9 cells the (2'-5')A synthetase activity remained unchanged. Simultaneously with the decr…
