The presenilin containing gamma-secretase complex is responsible for the regulated intramembraneous proteolysis of the amyloid precursor protein (APP), the Notch receptor, and a multitude of other substrates. gamma-Secretase catalyzes the final step in the generation of Abeta(40) and Abeta(42) peptides from APP. Amyloid beta-peptides (Abeta peptides) aggregate to form neurotoxic oligomers, seni...
Morphometric of examination gonads Liza carinata were performed for one year (October 1995 – September 1996) to study the maturation development. Monthly variation in gonado somatic index (GSI) noticed, that started with low values during October and November. Significant increase was recorded period December - April peak February (3.59 males & 9.33 females) followed by a significant declin...
The concept of Generalized Snapshot Isolation (GSI) has been recently proposed as a suitable extension of conventional Snapshot Isolation (SI) for replicated databases. In GSI, transactions may use older snapshots instead of the latest snapshot required in SI, being able to provide better performance without significantly increasing the abortion rate when write/write conflicts among transaction...
Glutamine synthetase exists in at least two related forms, GSI and GSII, the sequences of which have been used in evolutionary molecular clock studies. GSI has so far been found exclusively in bacteria, and GSII has been found predominantly in eukaryotes. To date, only a minority of bacteria, including rhizobia, have been shown to express both forms of GS. The sequences of equivalent internal f...
Gridpoint Statistical Interpolation (GSI) is an assimilation tool that is used at the National Centers for Environmental Prediction (NCEP) in operational weather forecasting in the USA. In this article, we describe implementation of an extension to the GSI for assimilating surface measurements of PM2.5, PM10, and MODIS aerosol optical depth at 550 nm with WRF-Chem (Weather Research and Forecast...
This paper presents engineering geological investigation results in the form of rock mass characteristics for tunnel number 1 Sigli-Aceh toll road. The was carried out through mapping, core drill evaluation, and laboratory tests. In this research, rating (RMR) Geological Strength Index (GSI) were applied classifications. measurement quality is then used to determine excavation method support sy...
Both the high energy experimental program and especially the GSI Therapy project require a uniform intensity distribution of the slowly extracted ion beam from the synchrotron SIS. At GSI a feedback system has been tested to improve both the coarse and the fine time structure of the spill.
Using advanced Laser spectroscopy methods, nuclear ground state spins, moments, charge radii, of radioactive nuclei can be determined. The optical techniques, based on hyperfine structure splitting (HFS) or isotope shift measurements, yield model-independent information about the nucleus. Various experimental methods and concepts are proposed to take advantage of the exotic nuclei provided at l...
