The level of development of each era determines the specifics of recognizing diseases and teaching about them. Nowadays, there is an increased interest taken by patients in their own appearance as well as in the structural features of the facial part of their heads. Another issue currently faced by the dentistry is the growing prevalence of dentofacial anomalies and deformities among various population groups. The etiological factors behind anomalies and deformities include dental system congenital and acquired pathologies, and especially dental arch defects . The effect of the dental arches pathology on the craniofacial status has been proven in numerous works written by clinical experts [8, 9]. It has been noted that the timely treatment and preventive measures offered to patients with dental arches defects through different age periods, has a beneficial effect on the growth, development and condition not only of the masticatory system, yet also on the adjacent organs and body systems . Given the above, studying maxillofacial morphology in people with dental arch defects will remain an urgent issue for dentistry

Modern data of the etiology of squamous cell carcinoma (SCC) of the mucous membrane of the oral cavity (MMOC) show an increasing prevalence of the disease, a high mortality rate despite the development of modern methods of diagnosis and treatment. SCC is a group of polyetiological diseases. Among the most often etiological factors the use of tobacco products is found as one of the main cause of the disease with the division into active or passive methods of their use, prevalence and potential pathogenicity. Also the risk of the development of SCC MMOC depends on the consumption of alcoholic product as the long-acting traumatic factor. There were analyzed and considered the most common precancerous diseases of the mucous membrane of the mouth, their private and common significance in the structure of precancerous diseases. There was revealed the high correlation between periodontal disease and the development of SCC MMOC, which corresponded to the general assumption about the risk of oncology development against the background of chronic infection in the oral cavity. There were identified new data of the relation between the carriers of some types of the viruses of human papillomavirus and the development of SCC MMOC. Particular understanding of the causal relation of presented on-copathology allowed judging the lack of preventive measures, the necessity of required qualification of specialists of dental and related profile.

Abstract Since the late 1980s, linguists’ analyses of Sheng, the urban youth language from Nairobi, have led to the growth of a considerable body of literature. In contrast, only a few studies are available that cover other youth registers from the Kiswahili-speaking parts of Africa. While most of the available studies either deal with techniques of manipulation or with adolescents’ identity constructions, our paper intends to give a comparative overview of specific morphological features of Kiswahili-based youth languages. While certain characteristics of Sheng (Nairobi/Kenya), Lugha ya Mitaani (Dar es Salaam/Tanzania), Kindubile (Lubumbashi/DR Congo) and Yabacrâne (Goma/DR Congo) largely diverge from East Coast Swahili (hereafter ECS) in regard to their nominal and verbal morphology, they all share specific features. Focusing on (apparent) supra-regional developments and changes in Kiswahili, this preliminary description of some structural features that transcend all four youth language practices aims to provide comparative insights into urban register variation, approaching East African youth languages from a micro-typological perspective.

Fluorapatite-zinc oxide (FAp-ZnO) composite nanopowders were successfully prepared via mechanochemical process. Characterization of the products was carried out by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) analysis, energy dispersive X-ray spectroscopy (EDX), and field-emission scanning electron microscopy (FE-SEM) techniques. Results revealed that in the absence of ZnO which produced by hydrothermal method, the single-phase FAp had high-crystalline structure with appropriate morphological features. Furthermore, after 5 h of milling in the presence of 5 wt.% ZnO, FAp-5 wt.% ZnO, composite nanopowders with no impurity phase was obtained. Structural studies illustrated that the milling up to 5 h was not accompanied by a remarkable change in the structural features. Moreover, the gained composite powders presented an average crystallite size of about 40 nm for FAp. The FE-SEM observations indicated that the experimental outcome had a cluster-like structure which consisted of several small particles. Finally, results propose a new approach to prepare commercial amounts of novel FAp-based composite nanopowders with high quality and suitable structural and morphological features.

Currently, there is a lot of literature and research that reflects data on the structure of the peripheral nervous system. However, it should be noted that the results available in the sources do not contain a full range of data on the structural features of paraneural structures and have some contradictions. In addition, data on the morphological features of the structure of the paranephrium of peripheral nerves in ontogenesis are practically absent. This was the beginning of our research, in order to obtain new, more in-depth data on the age-related variability of the peripheral nerve paraneurium.

In this paper, the author discusses the phenomenon of mobbing, or harassment at the workplace, by focusing on the concept, phenomenological characteristics and types of mobbing, the etiological factors leading to its emergence, and the consequences sustained by victims. Considering the need to have mobbing recognized and legally sanctioned as a form of harassment, the author underscores that the social response to mobbing must be conceived as a comprehensive system of preventive measures. This paper aims to provide an insight into this negative social phenomenon as a prerequisite for building an effective system of primary, secondary and tertiary prevention. In particular, the author provides an overview of the Serbian legislation on this matter and points to the role of the non-governmental sector in the prevention of mobbing.

Among the natural mechanisms that positively influence on the optimization of anthropogenically transformed soils, on sustainability of natural soils, there is saprophages’ pertinent activity. Typical representatives of saprophages within such functional group as «ecosystem engineers» are diplopoda. Their trophometabolic (excretory) function is a significant factor in the fertility soil rising. The object of the study – Rossiulus kessleri (Lohmander, 1927), the representative of Diplopoda (Julidae). The aim of the paper is studing the interdependence morphological features among R. kessleri individuals from different forest ecosystems (natural ash-maple oakery within subwatereshed-ravine landscape, natural maple-aspen oakery within terrace flood plain, maple standing forest within subwatereshed-ravine landscape) within the steppe zone of Ukraine. Statistical analysis, on the criterion of multiple comparison of averages (test Tukey) for females from three forest types, revealed statistically significant (P ≤ 0,05) differences in average width and length of it’s body, and in the length of the collum. For males from three forest types, significant differences (P ≤ 0,05) was found in width and length of the antennae, meanwhile for lingular plates’ length and width, and for length and width of the gnathochilarium, differences was not established. Analysis of morphological features connections was carried out using multiple regression methods, which allowed to develop mathematical models with high predictive power. It is established that morphological changes of some diplopoda’s structural features are correlated with one or several other ones. Multiple regression methods showed standing assemblages of quantitative characteristics that might be predicted by certain morphometric features both for males and females (for example by linear size of its body, or size of gnathochilarium elements). It is shown that antennae’s length and width, correlate with body length (for females) and body width (for males) respectively. As for gnathochilarium elements, for females a great number of features were determined as remained in mathematical models after statistical processing. Thus, lingular plates’ length and width might be predicted by additive (total) contribution of body’s length and width, and gnathochilarium length for females, and for males, respectively, only the by gnathochilarium width and by body’s length. The identified features are elements of morphological integration, which makes structural and functional integrity of organisms as a system.

The results of a biometric study of gypsum models of 174 people of the first period of adulthood with physiological occlusion of permanent teeth made it possible to calculate the boundaries of variability under normodontism, macrodontism, and microdontism for upper and lower dental arches. The length of the upper dental arch during normodontism with an interval of ‘three sigma’ varied from 109 to 117 mm, and the length of the lower dental arch was 101 to 114 mm. A decrease in biometric values by odontometric indicator beyond the limits of sigmal deviations for normodont indicators made it possible to distinguish a micro-type of dental arches, and an increase in biometric values – macro-standard. The calculated data on the relative morphometric values of the dental arches, the index of the ratio of the length of the dental arch to the transversal sizes (normodontism: upper jaw at 1.85 ± 0.20 cu, lower jaw at 1.94 ± 0.20 cu; macrodontism: upper jaw at 1.86 ± 0.03 cu; lower jaw at 1.88 ± 0.02 cu; microdontism: upper jaw at 1.82 ± 0.01 cu, the lower jaw at 1.83 ± 0.02 cu), as well as the index of the ratio of the length of the dental arch to the sum of the diagonal dimensions of both sides (normodontism: upper jaw at 1.05 ± 0.02 cu, lower jaw at 1.10 ± 0.02 cu; macrodontism: upper jaw at 1.07 ± 0.01 cu, lower jaw at 1.08 ± 0.02 cu; microdontism: upper jaw at 1.06 ± 0.02 cu, lower jaw at 1.09 ± 0.02 cu), it is advisable to use for the diagnosis of anomalies in the shape and size of the dental arches in clinical orthodontics and orthopedic dentistry.
