What happens when we remove GRACE or Ocean Bottom pressure from a GRACE+GPS+OBP joint inversion? Roelof Rietbroek, Sandra-Esther Brunnabend, Madlen Gebler, Mathias Fritsche, Jürgen Kusche, Christoph Dahle, Frank Flechtner, Schröter Jens, and Dietrich Reinhard
The movement of large masses, originating from hydrological and oceanographic variations, causes detectable
variations in gravity and surface deformation. These may be detected by satellite gravimetry and a network
of permanent GPS stations respectively. Alternatively, additional information on ocean bottom pressure(OBP)
variations may be retrieved from simulations.
Joint inversions offer a way to combine different data sources in order to obtain improved estimates of surface loading. This technique can be used to compensate for weaknesses in one dataset, by the strengths of the others. But what happens when one datasets is taken out of the equation?
Here, we compute a joint inversion using a GPS+GRACE+OBP combination. Additionally, we purposely
deteriorate the solution by removing either data from GRACE or OBP. The accuracy and resolution of the
solutions is discussed. Furthermore, regions are identified where the restricted inversion is consistent with the full inversion, and where the results show strong hydrological signals
Calibration of TCCON column-averaged CO2: the first aircraft campaign over European TCCON sites
The Total Carbon Column Observing Network (TCCON) is a ground-based network of Fourier Transform Spectrometer (FTS) sites around the globe, where the column abundances of CO2, CH4, N2O, CO and O2 are measured. CO2 is constrained with a precision better than 0.25% (1-σ). To achieve a similarly high accuracy, calibration to World Meteorological Organization (WMO) standards is required. This paper introduces the first aircraft calibration campaign of five European TCCON sites and a mobile FTS instrument. A series of WMO standards in-situ profiles were obtained over European TCCON sites via aircraft and compared with retrievals of CO2 column amounts from the TCCON instruments. The results of the campaign show that the FTS measurements are consistently biased 1.1% ± 0.2% low with respect to WMO standards, in agreement with previous TCCON calibration campaigns. The standard a priori profile for the TCCON FTS retrievals is shown to not add a bias. The same calibration factor is generated using aircraft profiles as a priori and with the TCCON standard a priori. With a calibration to WMO standards, the highly precise TCCON CO2 measurements of total column concentrations provide a suitable database for the calibration and validation of nadir-viewing satellite
Деловая карьера и ее развитие в Государственном профессиональном образовательном учреждении "Яшкинский техникум технологий и механизации" (пгт. Яшкино)
В современной России наблюдается разбалансированность рынка педагогического труда. Система образования не испытывает количественной нехватки преподавателей, но существуют трудности с удержанием молодых преподавателей и развитием уже работающих опытных специалистов. Цель работы – выявить особенности карьеры в образовательном учреждении современной России.Объект исследования – система управления деловой карьерой в организации.In modern Russia there is an imbalance of the market of pedagogical work. The education system does not have a quantitative shortage of teachers, but there are difficulties in retaining young teachers and developing experienced professionals who are already working. The purpose of the work is to identify the features of a career in an educational institution of modern Russia.The object of research is the system of business career management in the organization
Examination of macro- and microelements distribution between total extract and fractions for nootropic plant-derived raw material Alfredia cernua
The paper dwells on a quantitative determination of macro- and microelements in the ethanol Alfredia cernua extract and its chloroform, ethyl acetate, and butanol fractions. The distribution of macro- and microelements in the extract and fractions was investigated to further study of the interrelation between chemical composition and nootropic activity Alfredia cernua. It is shown that B, Fe, and Sn is mainly accumulated in butanol and Si, P, Al - in chloroform fraction respectively, but most macro- and microelements remain in the ethanol extract
Decreased expression of breast cancer resistance protein in the duodenum in patients with obstructive cholestasis
Background/Aims: The expression of transporters involved in bile acid homeostasis is differentially regulated during obstructive cholestasis. Since the drug efflux transporter breast cancer resistance protein (BCRP) is known to transport bile acids, we investigated whether duodenal BCRP expression could be altered during cholestasis. Methods: Using real-time RT-PCR analysis we determined mRNA expression levels in duodenal tissue of 19 cholestatic patients. Expression levels were compared to 14 healthy subjects. BCRP protein staining was determined in biopsies of 6 cholestatic and 6 healthy subjects by immunohistochemistry. Results: We found that in patients with obstructive cholestasis mean duodenal BCRP mRNA levels were significantly reduced to 53% and mean protein staining was reduced to 57%. Conclusions: BCRP, a transporter for bile acids and numerous drugs, appears to be down-regulated in the human duodenum during cholestasis. The clinical impact of these results has to be investigated in further studies. Copyright (c) 2006 S. Karger AG, Basel
