Abstract:

Odontoma, a mixed odontogenic tumor, is considered to be a hamartoma rather than a true neoplasm. Fully developed odontomas chiefly consist of enamel, dentin, pulp and occasionally cementum. They are subdivided into compound and complex types. The compound odontoma is composed of multiple, small tooth like structures, whereas the complex type consists of a conglomerated mass of enamel and dentin, having no anatomical resemblance to a tooth. They are usually asymptomatic, slow growing but cause bony expansion, which is often discovered during routine radiography. Here, we report a case of a com

Abstract This paper discusses various types of complex predicates found in Betta Kurumba, a South Dravidian language spoken in southern India. The constructions discussed include causativising and valency-modifying affixes, phrasal compound verbs, and compound verb stems. Compound verb stems are unusual for the language area, as they combine verb roots word-internally rather than as independent words, and have undergone varying degrees of grammaticalization. The origin of the compound verb stem construction is investigated, with the paper demonstrating that this construction was also originall

Abstract:

The synthesis of a zinc derivative of tribenzonaphthoporphyrazinato ( Zn -tri- PcNc ) obtained from 6-carboxymethyl-2,3-dicyanonaphthalene and phthalonitrile is described. This new phthalocyanine ( Pc ) compound was characterized by 1 H NMR, elemental analyses, IR and UV-vis. The spectroscopic analysis of this compound show an electronic spectrum in DMSO with characteristic bands in the Soret and ϱ region. Steady state and time-resolved spectral analysis revealed a fluorescence quantum yield and a fluorescence lifetime of Φf=0.22 and τf = 2.56 ns respectively, in agreement with other Pc deriva

Abstract:

Inner complex compound of cobalt(III) with diaminoethanol, [Co(DetmHdetm)], and polynuclear complex compound 2Co-Ni with diaminoethanol, [Ni(CoDetmHdetm)2](NO3)2, were synthesized. Stabilities of the obtained compounds were investigated in non-aqueous (dimethylformamide) solutions at different values of pH (from acid to alkaline). Methods of potentiometric titration and electron absorption spectra were used to determine the range of pH values where the compounds do not decompose. As a result of these studies, we found that at the upper value of pH=7, the coordination surrounding of the metals

Abstract:

The citral compound that contributes to the strong-lemony odour of lemongrass has high volatility and low physicochemical stability. To overcome the problems, the inclusion complex of the encapsulation technique was applied with rice starch as a coating material to improve the stability and protect against any unfavourable reaction. Therefore, this study was conducted to determine the structural characterization, citral retention and thermal properties of native rice starch, gelatinised rice starch, inclusion complex of rice starch–citral compound, and inclusion complex of rice starch–lemongra

Abstract:

The aim of the work was to study the antihypoxic properties of a number of complex zinc-containing compounds of nicotinic acid under the code πQ. The experiments were performed on male mice of the SHR line. Antihypoxic properties of compounds were studied on 4 models of acute hypoxia (hypoxia with hypercapnia, hypobaric, hemic, and histotoxic). It was found that the compound πQ-1043 in the dose spectrum of 10-100 mg/kg effectively increases the life expectancy of animals in all models of acute hypoxia. The compound πQ-1043 at a dose of 25 mg/kg reduces the oxygen consumption and rectal tempera

The article discusses the types of analytical method, their word-forming abilities and functions. It is known that the analytical method of creating complex words performs a very productive function in linguistics. The article describes the features of the method of repetition in the formation of complex adverbs of the word-forming system. In the study of complex adverbs, the theory of repeated words in linguistics was taken as a basis. Despite the fact that repeated words were studied in science comprehensively, in word-forming systems of parts of speech, complex words were not fully studied.

Abstract:

Nuclear magnetic resonance spectroscopy or NMR is a chemical instrument that can be used to evaluate the structure of a chemical compound other than FTIR, GC-MS, and HPLC. NMR spectroscopy commonly used for compound analysis is 1H-NMR and 13C-NMR. Techniques can be used to determine the structure conformation, the number of protons, and the number of carbons in the structure of a chemical compound. So far, there have been many publications related to the use of this spectroscopic technique. However, the steps in reading and interpreting the spectra of both 1H-NMR and 13C-NMR are not described

The charge transport properties and the stability of imidazoles with axial-coordinated protoheme molecules have been investigated by the density functional theory (DFT) at B3LYP/6-31[Formula: see text]G(d) level. With energy of each compound, we find that all heme Fe[Formula: see text] and Fe[Formula: see text] complex compounds axially coordinate the imidazoles by strong field in low-spin state. Meanwhile, binding energies were calculated, the structure feature and the frontier orbital distribution of complex compounds were also analyzed. On the basis of Marcus theory, the reorganization ener
