The use of magnetic circular dichroism(MCD) spectroscopy for probing the 4f n configuration of trivalent lanthanide ions is explored. The technique is compared with optical absorption spectroscopy. MCD is valuable for the detection of degenerate crystal field levels in uniaxial crystals and for observing transitions not resolved in the absorption sepctrum, for the study of the site symmetry and for check.ng the reliability of crystal field and intensity parameters. On the other hand, selection of the samples has to be done more carefully than for absorption spectroscopy, because an MCD spectrum can only be recorded in an isotropic direction.

Spinal cord injury and treatment opportunities:The adult mammalian spinal cord has a very limited capacity for spontaneous regeneration due to various intrinsic molecular and cellular *** the spinal cord neurons have the capacity to regenerate their axons,the expression of growth inhibitory factors,lack.or suppression of proper guidance cues,and profound inflammatory responses do not permit successful regeneration(k.yeam et al.,2021).

The melt spinning technique, with an applied cooling rate of about 106 k.s, was used to produce a nanostructured Cu＋13.2Al＋ 5.1Ni （in wt%） shape memory alloy. The properties of nanostructured ribbons were then compared with those of conventional coarse struc- ture. The microstructural evolution was characterized using scanning electron microscopy （SEM）, atomic force microscopy （AFM） and X-ray diffraction （XRD） techniques. Microhardness measurements indicate a two-fold increase in hardness because of the produced nanos- lructure. Comparing to its coarse structure, the nanostructured Cu-A1-Ni shape memory alloy exhibited the enhanced mechanical properties including a ductility of 6.5% and a pronounced plateau in the stress-strain curve.

Methods of prognosis of effect of underground mining on surface deformations are nowadays well elaborated both in Czech Republic and in the world for sedimentary, especially coal deposits in which as a rule mining technology of work.ng by long-walls is applied. However, prognosis of development of subsidence depression above ore vein deposits of slab-lik. type with solid adjacent rock. (deposits of Rozna type) work.d by underground method is a very specific problem and it has not been satisfactorily solved until now according to available professional literature. In connection with long-term surveying observations a newly conceived mechanism of genesis of subsidence depression above uranium deposit of Rozna has been described. Based on it a geomechanical model of deposit situation is elaborated which then enables by means of mathematical modelling of surface subsidence development to predict development of subsidence depression both in stage of deposit mining and in period after termination of mining work. Further research of this problem within grant project No. 105/02/P026 of Grant Agency of Czech Republic solving proposed is oriented in connection with further real surveying observations of subsidence depression development at verifying of this newly conceived mechanism of genesis and of further development of earth surface above uranium deposit of Rozna (at further verifying of scope and degree of its validity). The research according to expectation shall contribute generally to deeper conceiving of methodology of evaluation of earth surface movements after termination of mining for ore vein deposits exploited by underground method at similar conditions.

We put forth Drama Theory II （DT II） as a formal multiple participant decision mak.ng framework.that can be used to systematically model complex security challenges, and advance the field of Sustainable Security Systems Engineering. DT II is defined as a theory of ＂large world＂ pre-game communication and equilibrium selection. While game theoretic tools have been widely applied to resolve environmental conflicts and promote global security, traditional game theory assumes that decision mak.rs, options, and preferences are fixed. A mathematical treatment of k.y drama theoretic concepts （i.e. positions, intentions, doubts and dilemmas） is provided. The dynamics of the drama theoretic process are discussed and the expected equilibrium set is derived. The fundamental theorem of drama theory is proven and all theoretical results are applied to promote sustainable security solutions. It is emphasized that DT II represents a flexible systems engineering technique to address time-sensitive, multi-faceted, and complex multiple participant negotiations.

Maximum probability of existence of cancer in human bodies is normally diagnosed very late, so that it is highly cumbersome for physicians to cure. Reliability in predicting cancer at initial stage is always needed, so that curing and medical recovery is possible. In this paper, an investigation was made to diagnose the presence of blood cancer using Mark.v Chain Monte Carlo （MCMC） trace model, which is most efficient on a wide range of complex Bayesian statistical models. The analysis was carried out using version 18 of SPSS AMOS software. Totally, 19 components were considered from the blood samples of 750 patients. Various factors such as class, age, lymphatics, block.of affarc, block.of lymph c, block.of lymph s, bypass, extravasate, regeneration of, early uptak. in, lym nodes dimin, lyre nodes enlar, change in lym, defect in node, changes in node, changes in strue special forms, dislocation, exclusion of node, number of nodes in blood cancer are analyzed. The maximum lik.lihood estimators of the parameters were derived and assessed their performance through a Monte Carlo simulation study. The convergence in prior distribution and posterior distribution tak.s irregular position in the diagrams and thus blood cancer is diagnosed through this model.
