The samples of fir'e hybrid dendrimer (lactopolypropylene imine) generations were studied by the methods of molecular hydrod-vnamics, including the sedimentation velocity. translationa] diffusion, and intrinsic viscosity measurement s in 0.l65Vo aqueous NaCl solutions. The molecular masses (1.9 < M sDx 10-3 < 46.5) and the corresponding hydrodynamic dimensions of the dendrimer molecules were de...

Rewrite systems axe collections of directed equations (rules) used to compute by repeatedly replacing subterms in a given formula until a simplest form possible (normal form) is obtained. Many formula manipulation systems such as REDUCE or MAGSYMA use equations for simplification in this manner. Canonical (i.e., terminating Church-Rosser) rewrite systems have the property that all equal terms (...

Diagnosis is essential for the management and treatment of patients with rare diseases. In a group patients, genetic study identifies variants uncertain significance or inconsistent phenotype; therefore, it urgent to develop novel strategies reach definitive diagnosis. Herein, we in-house Translational Diagnostics Program (TDP) validate as part diagnostic process close collaboration physicians,...

Uridine-cytidine kinases (UCK) have important roles for the phosphorylation of nucleoside analogs that are being investigated for possible use in chemotherapy of cancer. We have cloned the cDNA of two human UCKs. The '30-kDa proteins, named UCK1 and UCK2, were expressed in Escherichia coli and shown to catalyze the phosphorylation of Urd and Cyd. The enzymes did not phosphorylate deoxyribonucle...

In this paper we provide an overview of the GlobGlacier project, a new data user element activity within ESA’s Living Planet program. The main aim of the project is to map glaciers from key regions all over the world and to generate digital glacier outlines in large quantities in order to fill data gaps in currently existing databases (GLIMS and World Glacier Inventory, WGI). Further goals are ...

There has been for some time, and will continue to be an increasing need for the storage and retrieval of complex data structures. Databases are already a major part of the operations for organizations and businesses; however, they are now increasingly being used for research purposes, for storing complex data structures that arise but are not reflected in the business paradigm. The aim of this...

The beginnings of agriculture in eastern Asia date to Neolithic times, 7000 to 9000 years ago, with rice cultivation about 4000 BCE. Agricultural origins in the Indus valley occur about the same time. In North China and Manchuria, a civilization was established about 2000 BCE and by the Zhou dynasty, 1000 BCE, there is evidence of canals and extensive irrigation. The writings of Confucius (551–...
