The Typical Topic Model of Scientific Research of Terrorism

In this original scientific paper, we consider terrorism as a phenomenon and process, that is, the possibilities of scientific research of terrorism by the typical research topic model. The typical topic model of scientific research of terrorism in social sciences, especially in political science, given that terrorism is primarily a political phenomenon, is a general model that applies to both terrorism and terrorist activities

A Method for the Spectroscopic Diagnostic of the Peculiarities of Materials Using the Semi-Auger Effect

We investigated the low energy satellites in the Rontgen spectra using the many-particle theory. These satellites are results of the radiative semi-Auger decay of the inner vacancy states. We did not treat only ordinary radiative decay. There exist the excitations of one of the atomic electrons together with the photon emission. We presented results of radiative semi-Auger decays of vacancy states in Ar atom. The knowledge of these processes is important for understanding the same processes in the case of the nanoparticles (molecules, fullerenes, clusters). Research in the field of the new materials requires more sophisticating methods which will open the new possibilities for obtaining materials of particular design, too. The theory which is presented in the paper may be easily generalized in case of particles like fullerenes and clusters.10th Annual Conference of the Materials-Research-Society-of-Serbia, Sep 08-12, 2008, Herceg Novi, Montenegr

A possible connection between phosphate tungsten bronzes properties and briggs-rauscher oscillatory reaction response

The calcium phosphate tungsten bronze (Ca-PWB) has been synthesized and characterized (TGA, DSC, XRPD, FTIR, SEM). The influence of solid insoluble materials Ca-PWB, as well as lithium doped (Li-PWB) and cation free phosphate tungsten (PWB) bronzes on the oscillatory Briggs-Rauscher (BR) reaction dynamics, is compared. The results show that doping with Li and Ca reduces sensitivity of the BR reaction towards bronzes addition. These findings suggest the usage of the BR reaction as an innovative method for testing of different properties of bronze material. The behavior of PWB in the BR reaction is significantly changed with divalent cation (Ca2+) doping. The reasons for the different bronzes behavior were found in their calculated unit cell volumes. Namely, the compressed Ca-PWB unit cell volume indicates the difficult availability of the active site for heterogeneous catalysis. Hence, the linear correlation (slope) of the BR oscillogram’s length (τosc) vs. mass of bronze in BR reaction might be considered as a new parameter for the evaluation of the bronzes catalytic activity

Microsatellite variation of ESR1, ESR2, and AR in Serbian women with primary ovarian insufficiency

OBJECTIVE: This study aimed to investigate the potential role of microsatellite polymorphisms of the estrogen receptor alpha gene (ESR1) TA repeat, estrogen receptor beta gene (ESR2) CA repeat, and androgen receptor gene (AR) CAG and GGN repeats among Serbian women with primary ovarian insufficiency (POI). These microsatellites have been reported to be associated with POI in different racial/ethnic populations. METHODS: A cohort of 196 POI cases matched with 544 fertile controls was recruited by the Institute for Endocrinology, Diabetes and Metabolic Disorders of Serbia between 2007 and 2010. DNA was extracted from saliva. The four microsatellites were genotyped using a PCR-based assay to determine the repeat lengths. RESULTS: POI patients carried shorter repeat lengths of ESR2 (CA)n than controls (P = 0.034), but the difference was small. ESR1 (TA)n was on the borderline of statistical differences between groups (P = 0.059). AR (CAG)n and (GGN)n showed no association with POI. CONCLUSIONS: We cautiously conclude that microsatellite polymorphisms of gonadal steroid receptor genes might contribute to the genetic basis of POI in Serbian women, but a larger-scale study and family-based studies are warranted to validate our findings even though the sample size in this study is larger than any previously published in this field
