Abstract The article presents the results of studies brown and black coals from Angren Shargun deposits Republic Uzbekistan. According to research, a number different non-ferrous noble metals were revealed in their composition: Tungsten up 2 wt.% Au, Ag as well rare earth elements (REE). Methods techniques have been developed for extraction precious coals: Ag, Au Ge Sc. Scientists laboratory In...

According to the assumption that si = sj for i = j, the matrix (5) has an inverse and the system (2) and (4) can be solved. We denote by V the Vandermonde determinant of the matrix (5) and by Vk the Vandermonde determinant of order (n − 1) of the variables s1, . . . , sk−1, sk+1, . . . , sn. We also denote by Φ r the fundamental symmetric function of the r-th order of (n − 1) variables s1, . . ...

The random priming DNA-labeling method of Feinberg and Vogelstein (1, 2) produces probes of high activities. However, incompletely denatured templates in the reaction mixture may cause problems. In addition, probes generated by the standard random priming method are not ideal for in situ hybridization or other methods requiring only one labeled strand. We have developed a method utilizing a bio...

Human granulocyte colony stimulating factor (hG-CSF) induces proliferation and differentiation of granulocyte progenitor cells. This glycoprotein is currently being used for treatment of neutropenia, in patients who have undergone bone marrow transplantation. So far, different researchers have tried to enhance hG-CSF biological activity and stability. In this study, Polymerase Chain Reaction (P...

Let sk (k = 1, . . . , K) denote the locations of theK = 17 temperature series. At each location k we observe M(sk) temperature values z(sk) = (z1(sk), . . . , zM(sk)(sk)) T drawn from the M(sk)-variate random vector (RV) Z(s). Suppose at location k that these observations correspond to times Tt(sk), for t = 1, . . . ,M(sk). Since all sampling in the MCMC algorithm is performed on the wavelet d...

A problem frequently encountered during the construction of new plasmid vectors is the lack of suitable restriction sites for the insertion of foreign DNA. This problem is particularly common during the cloning of DNA restriction fragments into retroviral and eukaryotic expression vectors, as these vectors are often very large with few cloning sites available. The standard approach is to modify...
