Crime as a negative social phenomenon and as a socially dangerous activity can be characterized from various sides: sociological, criminological, criminal procedural, criminalistic. Forensic characteristics of a crime is a collection of such data about it, which contribute to the disclosure of crimes. Therefore, when investigating crimes, the forensic characterization of crimes is invaluable, which represents a system of information about the typical features of a certain category of crimes, the analysis of which contributes to the rapid and effective investigation of crimes. In the forensic description, data on the situation of the commission of a crime are the main ones, since they contain information about its other elements. Key words: forensic characterization, investigation, the elements, setting of the crime, criminal legislation

Reaction of McConville's chelating amido titanium complex [(Ar)NCH2CH2CH2N(Ar)]Ti(CH3)2 (Ar = 2,6-i-Pr2C6H3) with either elemental Se or the tellurium atom source Te=PBu3 resulted in the formation of bis-µ-chalcogenido dimers [(Ar)NCH2CH2CH2N(Ar)]2Ti(µ-E)2 (E = Se, 2; Te, 3) with concommitant loss of EMe2. The dimers 2 and 3 were characterized spectroscopically and via X-ray crystallography. The two compounds are isostructural in the solid state. The tellurido dimer 3 may also be synthesized by reduction of the diamido dichloride [(Ar)NCH2CH2CH2N(Ar)]2TiCl2 with Na–Hg amalgam followed by treatment with Te=PBu3. This dimer is unreactive toward further Te=PBu3 or stannanes such as HSnBu3. Unlike decamethyltitanocene derivatives, the diamido complex is not an effective catalyst precursor for the heterohydrodecoupling of Te=PBu3 and HSnBu3.Key words: diamido titanium complexes, selenides, tellurides.

A morphological and anatomical study of the mycorrhizas on Pinus strobus L. was conducted on seedlings excavated from St.-Williams nursery in southern Ontario. Micro- and macro-scopic characters were used to classify the morphotypes into complexes and, when possible, genera and species. An E-strain fungus, fungi from the Mycelium radicis atrovirens (MRA) complex, and an unidentified ascomycetous "red-type" fungus formed ectendomycorrhizal (EECM) associations, while Tuber sp., Hebeloma sp., and Thelephora terrestris formed ectomycorrhizal (ECM) associations in the nursery. Cultures of Hebeloma sp., the E-strain fungus, Tuber sp., and two morphologically distinct MRA fungi (MRA1, later identified as Phialophora finlandia Wang & Wilcox, and MRA2, unidentified) were isolated from field-collected morphotypes and re-inoculated onto Pinus strobus seedlings grown in semisterile pot cultures for 4 months. In the resynthesis experiment, the E-strain fungus formed EECM with sparse intracellular colonization, and Tuber sp. formed ECM with characteristic cystidia and densely packed mantles, as they had in the field. However, unlike the MRA field specimens, Phialophora finlandia formed ECM in pot culture. Hebeloma sp., normally an ECM former with conifer seedlings, did not form mycorrhizal structures under the given culture conditions, and neither did the MRA2 isolate.

Spectroscopic and structural features are presented for the first homologous series of diazadipnictetidines, which have the general formula [DipNPnN(H)Dip]2 (Pn = P, As, Sb, Bi; Dip = 2,6-diisopropylphenyl). The compounds are obtained from a general reaction of the corresponding halopnictine with excess LiN(H)Dip, which was previously reported for [DipNBiN(H)Dip]2. However, isolation is improved by the introduction of LiN(H)-t-Bu (at the appropriate stoichiometry) following the addition of LiN(H)Dip. The intermediate steric presence of the Dip substituent is suitable to support the heterocatenate framework for all homologues. This is in contrast to the small substituents (e.g. alkyl), which enable both bis- and tris-amination, and the larger substituent (Mes* = tri-tert-butylphenyl), which can impose coordinative unsaturation (aminoiminopnictine) for the smaller congeners (P and As).Key words: phosphorus, arsenic, antimony, bismuth, phosphazanes, phosphetidines, synthesis, structures, spectroscopic characterization.

Three new mixed oxides having the nasicon structure and containing arsenic(V) as tetrahedral ion were prepared and X-ray analyzed. The stoichiometry of the three phases can be expressed by the comprehensive notation MeZr2As(3−x)PxO12 where Me stands for Na+ or K+, x equals to 0 and 1.5 when Me=Na, while x equals to 1.5 when Me=K. For two other compositions of the above series, the powder patterns were calculated on the basis of the structural data from single crystal determinations, thus permitting us to complete the characterization of the solids, with nasicon framework, deriving from MeZr2P3O12 (Me=Na+, K+) by partial (50%) or complete (100%) substitution of As for P.Key words: nasicon, ionic conductors, phosphates, arsenates

Lactose Fermentation

Partial lactose-positive (Lac+) revertants, designated RS0121 and RS033, were isolated from lactose-negative (Lac−) mutants of Lactococcus lactis subsp. lactis C2 and ML3, respectively. These revertants were found to coagulate 10% reconstituted skim milk, but the rate of lactose fermentation was much slower than that of their parental Lac+ strains. Such partial Lac+ revertants were also isolated from Lac− mutants of L. lactis subsp. Lactis SL712, SH4109, and SL763 and of L. lactis subsp. cremoris ML1 and SC607, showing a generalized phenomenon. The Lac+ characteristic of the revertant strains was conjugally transferred to Lac− variants. When the plasmid profiles of the Lac− variants and their partial Lac+ revertants and transconjugants were analyzed, there were no detectable differences in the plasmid bands. A strain with no plasmids, MG1363, also yielded partial Lac+ revertants, which were devoid of all plasmids. In addition, the Lac+ phenotype of one such revertant, designated RS101, was transferable to other Lac− strains by conjugation. The results indicate that the genetic information for slow lactose metabolism in such partial Lac+ revertants is mediated through chromosomal gene(s) and is under the influence of some suppressor. These observations also suggest the possibility of utilizing this method for isolating slow acid producing variants, which could be used as adjuncts with regular cheese starter cultures for accelerated cheese ripening. Key words: lactococci, lactose-negative mutants, plasmid DNA, lactose-fermenting revertants.

State Stress

The limitations of critical state representations of sand behaviour are discussed and it is shown that stress dilatancy is an implicit part of a critical state framework. It is then argued that dilatancy leads to underestimates of bearing capacity factors in the method of characteristics. Kinematic constraints should also be considered in such calculations. Both dilatancy and kinematic constraint may be introduced into a stress characteristics approach while preserving critical state characterization of sand, using the technique known as the method of associated fields. Key words: bearing capacity, critical state, stress dilatancy, method of characteristics.

Inducible Genes

Unicellular algae acquire the ability to raise their internal CO2 concentrations under low-CO2 conditions because of the presence of a CO2 concentrating mechanism (CCM). In Chlamydomonas reinhardtii, this mechanism is induced when cells grown in high-CO2 conditions are switched to low-CO2 conditions. To elucidate the genes and proteins involved in this mechanism, we constructed a cDNA library from low CO2 adapted cells and differentially screened the library for cDNAs upregulated under low-CO2 conditions. Earlier studies identified six classes of clones specific to low CO2 adapting cells. To identify other genes and proteins playing a role in this mechanism, we have systematically characterized the cDNA clones that appear to be upregulated by low-CO2 adaptation but do not cross-hybridize with the six previously identified classes. We identified seven new classes of clones that are distinctly upregulated in low-CO2 conditions. These clones were checked by Northern analyses, sequencing, and homology studies. One class of clone represents a novel gene, lci 3. We report on the seven classes of clones and the characterization of lci 3.Key words: Chlamydomonas, CO2 concentrating mechanism, gene regulation, inducible genes, gene expression.

Category: 1.01 Original scientific paper Language: Original in Slovenian (Abstract in Slovenian and English, Summary in English) Key words: the October revolution, ideology, philosophy, imperialism, society Abstract: The article discusses the October Revolution as a key event of the 20th century, which as such, however, confronts us with the question of revolution in general. Revolution should not be understood purely as a specific social phenomenon, but in the context of the totalization of social subjectivity, which can also take on a totalitarian form. Within this, a new reflective horizon opens regarding totalitarian ideology as a tool and a weapon in the function of social power. Finally, we are confronted with the philosophical question, what is happening—not only because of the millions of victims of revolutionary terror, but also because of the nihilistic expansion of social subjectivity—with the essential meaning of humanity and individual existence.

An allelic rDNA variant from the Nor-B2 locus of 'Bezostaya' wheat that forms an especially active nucleolus was cloned and characterized. It carries an unusually large intergenic spacer compared with rDNA units in most other wheat genotypes. The additional intergenic length is in the array of 135-bp A repeats and not in other internal repeats. These A repeats have sequences nearly identical to other A repeats described for other alleles. It is suggested therefore that the more active Nor-B2 locus of 'Bezostaya' may be due to the constituent rDNA units possessing a larger array of A repeats. Key words : ribosomal DNA, nucleolar organizer region, A and B repeats, allelic, spacer length variants.

The genomes of the two species in the genus Salmo (Atlantic salmon, S. salar; brown trout, S. trutta) contain a 380-bp repetitive element that is flanked by the recognition sequence of the restriction enzyme NheI. These elements, which comprise approximately 1.2% of the salmon genome, do not exist in long tandem arrays as is typical of satellite DNA. A comparison of the sequences of 16 salmon and 7 trout elements revealed that members of this family of repetitive DNA are closely related to one another (over 95% identity). Subfamily structure exists and there is evidence that members of the same subfamilies are found in both Salmo species. A search of the GenBank database indicated that sequences homologous to the NheI repeat are located within a 1424-bp segment inserted immediately downstream of the 5′ end of a Tc1 transposon-like sequence isolated from Atlantic salmon (A.R. Radice, B. Bugaj, D.H. Fitch, and S.W. Emmons, unpublished data; GenBank accession No. L12206).Key words: satellite DNA, Atlantic salmon, brown trout, Tc1-like transposon, evolution.
