Dental Anthropology-A Revolutionary Tool in Forensic Science

Dental anthropology is a field of physical anthropology that studies the origin, development, and evolution of anthropoid dentitions, as well as their relationship to social, physical, and cultural factors. Teeth have their own distinct morphology and physiology, which is in stark contrast to the body's genetic structure. Teeth are also unique among the resistant elements of archaeological and fossil remains in that they have been exposed on the body's surface throughout their lives. As a result, dental anthropology may be assessed in the mouth cavity of living humans using similar methods to those used for prehistoric relics. As a result, it's no surprise that practising dental surgeons have historically ranked well among dental anthropologists. This review’s initial purpose is to provide an overview of the morphological and non-morphological properties of animate dentitions that aid in the indirect identification of prehistoric remains and the understanding of their cultural, social, and physical relationships, as well as to assist forensic odontologists with craniofacial identification and skull bone reconstruction.

FUNDAMENTAL AND APPLIED LECTINOLOGY IN RESEARCH OF PROFESSOR ANTONINA YASHCHENKO (on the occasion of 75th birthday anniversary)

Professor Antonina Yashchenko belongs to the group of outstanding morphologists, who developed and continue working productively for the popularization and implementation of the fundamental aspects, as well as spreading of applied lectinology methods in the morphologic research. As the result of her numerous studies in the field of lectin histochemistry were received new data on the applicability of a set of original lectin preparations purified and characterized in the «Lectinotest» from raw materials of the Carpathian region. Lectin-peroxidase and lectin-gold conjugates were applied in immunobiological research, light and electron microscopy, the methods of indirect identification of lectin receptors were worked out. Eventually these results were collected in a DSci dissertation of A. Yashchenko «Lectins as markers in normal and pathological conditions», conferred in 2004. This dissertation included a huge amount of authorized observations concerning wide possibilities of lectin histochemistry methods for studies of cell differentiation, identification of cellular subpopulations and diagnosis of pathological processes. Professor Yashchenko intensely studied the patterns of the rearrangement and redistrubution of lectin-reactive glycopolymers in the process of embryonic and postnatal morphogenesis, found out the possibilities of lectins’ application as selective histochemical markers of certain types of cells; studied the heterogeneity of lectins binding to cellular subpopulations depending on their tissue and organ specificity, as well as on the degree of their differentiation. Based on the results of the conducted research Prefessor Yashchenko published more than 250 papers in the professional journals, as well received 2 certificates of inventions. Published in 1999 «Atlas of Microanatomy of the Oral Cavity Organs» of her authorship got «The Yaroslav Mudryy award» of the Academy of Sciences of Higher School of Ukraine. Professor Antonina Yashchenko participated as a co-author in the National textbooks «Histology, cytology, and embryology» for Medical (2018) and Dentistry (2020) students. For these, as well as other morphology-related activities, in 2021 she was granted «A honorary award of the Ukrainian scientific society of anatomists, histologists, embryologists and topographo-anatomists»

A deepening understanding of animal culture suggests lessons for conservation

A key goal of conservation is to protect biodiversity by supporting the long-term persistence of viable, natural populations of wild species. Conservation practice has long been guided by genetic, ecological and demographic indicators of risk. Emerging evidence of animal culture across diverse taxa and its role as a driver of evolutionary diversification, population structure and demographic processes may be essential for augmenting these conventional conservation approaches and decision-making. Animal culture was the focus of a ground-breaking resolution under the Convention on the Conservation of Migratory Species of Wild Animals (CMS), an international treaty operating under the UN Environment Programme. Here, we synthesize existing evidence to demonstrate how social learning and animal culture interact with processes important to conservation management. Specifically, we explore how social learning might influence population viability and be an important resource in response to anthropogenic change, and provide examples of how it can result in phenotypically distinct units with different, socially learnt behavioural strategies. While identifying culture and social learning can be challenging, indirect identification and parsimonious inferences may be informative. Finally, we identify relevant methodologies and provide a framework for viewing behavioural data through a cultural lens which might provide new insights for conservation management.

Comparatory identification of taxonomy of automated control system in sea ports

The article considers a corporate taxonomy concept as a hierarchical classification of organization or administration, a form of organizing data (documents, digital assets, etc.). There is given the idea of the corporate taxonomy of seaports, branched hierarchy of concepts, objects and subjects of ports, extracted from the hidden knowledge of unstructured textual information and studied for the classification of electronic documents and other sources of information. It has been stated that one of the highest forms of human intellectual activity is understanding and extracting semantic units with their organization into a hierarchical structure. The most convenient and effective method of indirect identification is the method of comparative identification, which deductively uses the basic provisions of the theory of intelligence. There are considered processes of data processing in organizational information systems, surjective imaging, where each element of the value domain has at least one prototype. A system of logical equations showing the regularities of signal processing is given. The logical scheme of using the method of comparative identification for extracting non-obvious knowledge is illustrated. To compile the corporate taxonomy it is necessary to identify classes of conditional equivalence (in addition to classes of unconditional equivalence) that contain groups of close semantic units and have common features that will be grouped into one taxon. The descriptors of lexical units are presented. It has been inferred that the method of comparative identification used to create the corporate taxonomy allows to move from the subjective perception of meanings to the objective relationship between the documents in the automated system of seaports and the semantic units represented by keywords, headings, etc.

Highland Influence on Chronic-bacterial-prostatitis and Developing-reason of Prostate-cancer, KSA

This work was for "Highland (HL) Influence on Chronic-bacterial-prostatitis (CBP) and Developing-reason of Prostate-cancer (PCa), KSA"; the purpose was to determine CBP percentage at HL "Taif"; and influence of location factors on CBP percentage and indication of its developing-reason to causing PCa. It may negatively affected other body organs and may reach death of males' society, affected marital and community life. Used medical methods for cases taster (CsT) from patients were diagnosed as suffered from CBP. That were used direct and indirect identification by "CHROMagar Orientation Medium", and "VITEK 2 System (BioMerieux, France)". The pathogenic bacteria were found in more than a quarter of the CsT as (26 and 29%). That were Staphylococcous aureus (Staph. aureus), Escherichia coli (E. coli), Staphylococcous epidermidis (Staph. epidermidis) and Streptococcus species (Strept. Spp) in (36.2%, 9.5%, 5.7% and 4.3%) respectively. Pathogenic bacteria Staph. aureus represented more than third of CsT. E. coli represented tenth and it was dangerous for its transmission from UT and GT easily. Staph. epidermidis was present on the skin and represented normal flora can easily contaminated. Strept. Spp represented less than tenth, can transferred to prostate tissue and cause CBP leading to PCa. Concluded the CBP infection was present in HL and had developing-reason for PCa, the conditions must followed to reduce it to prevent condition of turning into PCa. Recommended best periodic follow-up to detect CBP infection presence to protect against infection and its PCa developing-reason. Cases CBP infection must treated and PCa cases should not neglected or tolerated.

Trajectory Identification for Moving Loads by Multicriterial Optimization

Moving load is a fundamental loading pattern for many civil engineering structures and machines. This paper proposes and experimentally verifies an approach for indirect identification of 2D trajectories of moving loads. In line with the “structure as a sensor” paradigm, the identification is performed indirectly, based on the measured mechanical response of the structure. However, trivial solutions that directly fit the mechanical response tend to be erratic due to measurement and modeling errors. To achieve physically meaningful results, these solutions need to be numerically regularized with respect to expected geometric characteristics of trajectories. This paper proposes a respective multicriterial optimization framework based on two groups of criteria of a very different nature: mechanical (to fit the measured response of the structure) and geometric (to account for the geometric regularity of typical trajectories). The state-of-the-art multiobjective genetic algorithm NSGA-II is used to find the Pareto front. The proposed approach is verified experimentally using a lab setup consisting of a plate instrumented with strain gauges and a line-follower robot. Three trajectories are tested, and in each case the determined Pareto front is found to properly balance between the mechanical response fit and the geometric regularity of the trajectory.
