Evaluation of The Antioxidant Potentials of African Nutmeg (Monodora Myristica) Extraction Palm Oil Stability
Authors: Mofio B.M. , Adeyanju O.Z.
Published: November 2021

Palm Oil contains high content of carotenoids and is a rich source of vitamin E consisting of tocopherols and tocotrienols which are well known nutritional antioxidants. Lipid oxidation has seriously limited the stability of palm oil resulting in rancidity. Therefore this work evaluates the antioxidant potential of Monodora myristica (African nutmeg) on Palm oil stability. Monodora myristica extract was obtained by maceration technique using n-hexane as solvent. Equal volumes of Palm oil obtained from one source were treated with different volumes (0.2ml, 0.4ml, 0.6m, 0.8m, 1.0ml) of African Nutmeg extract using syringe. Two experimental groups were prepared. A group were placed under the sun (S.S) and the other group in a room (S.R) for a period of two weeks. These treated oil samples were analyzed by titration, on weekly basis to determine the free fatty acid content and acid value. Results obtained showed that for the two groups of treated Palm oil, the free fatty acid content and acid value increased significantly (P<0.05 and P<0.01) at lower volumes of extract and as the period (week) extends. The free fatty acid content and acid value of oil samples treated with higher extract volumes decreased significantly (P<0.05 and P<0.01) for both groups (S.S and S.R). However all the values were higher than pre-treatment values. Hence, Monodora myristica extract reduces effect of lipid oxidation on palm oil and consequently increases its stability.

Authors: Omeje J.N. , Akinbobola J.S.
Published: November 2021

A cross sectional survey of trypanosomosis of pigs was carried out in three randomly selected Local Government Areas (Nsukka, Udenu and Igbo Eze South) out of the six local government areas in Enugu North Senatorial Zone. Blood samples were randomly collected from a total of 1800 pigs from abattoirs and farms and were examined for trypanosomes parasites using standard parasitological methods: wet film, buffy coat and Giemsa-stained thin smear preparations. A total of 93 (5.2%) pigs were positive overall. Among the positive samples, Trypanosoma brucei was the predominant species (86.0%), followed by T. congolense (13.9%). The different relative isolation rate for Nsukka, Igbo-Eze South and Udenu Local government areas were 14 (4.7%), 14 (4.7%), and 19 (4.0%) respectively in the dry season, and 17 (5.7%), 17 (5.7%) and 12 (6.3%) in the rainy season respectively. The trypanosome prevalence in males from Nsukka, Igbo-Eze South and Udenu local governments were 6.5%, 6.2% and 4.2% respectively, while report in female were 3.8%, 4.1% and 5.9% in the three local governments respectively. There was no significant variations (p<0.05) with seasons, sex and age groups. It was therefore concluded that porcine trypanosomosis is still endemic in Enugu North Senatorial Zone with T. brucei being the most incriminated as the cause of the disease in the zone.

Authors: Korzerzer R.M.
Published: November 2021

In this study, ten African striped ground squirrels (ASGS) (Xerus erythropus) obtained in Zaria and environs with the aid of traps between January and May, 2017 were transported in iron cages to the research laboratory in the Department of Veterinary Anatomy, Ahmadu Bello University, Zaria. After acclimatization for twenty-one days, the animals were weighed separately using a weighing balance (Fuji Keiryo weighing scale K-1, 210 × 210, 200g – 8kg) and then Thiopental sodium was administered at the dose of 30mg/kg to euthanize the animals. The testes, epididymis, ductus deferens and penis were then obtained by making an abdomino-pelvic incision and exposing the organs. Each organ was studied grossly. Observations for shape, colour and general architecture were made and photographs taken using a digital camera(Samsung SH100, 14.2 megapixels). From this study the testes of ASGS is dark-red in colour. The left and right epididymis is closely attached on the left and right testis. Each epididymis is anatomically divided into catput, corpus and caudal epididymis. The caudal epididymis has two aspects as the fixed and free part of the caudal epididymis. The penis is long and slender with an average length of 8.5 cm, and appears white in colour. The glans is covered by an external prepuce in the non-erectile state. The baculum is a sickle shaped single bone on the glans, and it has an average length of 1.9 cm. The prostate gland is a single gland just below the urinary bladder, the bulbourethral gland is located in the ishio-carvenosus muscle at the crura of penis, and closely attached to the distal aspect of the pelvic urethra linking the penis. The seminal vesicles are paired, and oval shaped glands proximal to the urinary bladder. In conclusion, the gross appearance of the male reproductive organs of the ASGS has anatomic modifications which is suggestive of its mating tendencies in the wild.
Gastrointestinal Parasites of Local And Exotic Breeds of Turkeys [Meleagris gallopavo] In Gwagwalada Area Council, Abuja, Federal Capital Territory, Nigeria
Authors: Jegede O. C
Published: November 2021

This study was carried out to determine the gastrointestinal parasites in local and exotic breed of turkeys reared in Gwagwalada, Guinea savannah Zone of Nigeria. It was conducted between May and September, 2017. One hundred [100] faecal samples were collected from local and exotic breeds of turkeys in Gwagwalada Area Council and examined for the presence of gastrointestinal parasites eggs and oocysts using flotation and sedimentation methods. The following parasites eggs/oocysts were identified in the study; Ascaridia spp [47%], Strongyloides spp [32%], Cappilaria spp [26%], Heterakis spp [25%], Tetrameres spp [24%], Spirurid spp [15%], Raillientina spp[13%], Davainea spp [10%], Subulura spp [6%], Oxyuris spp [6%], Cyathostoma spp [5%], Syngamus spp [5%]. The Oocysts identified belonged to Eimeria spp [41%], Cryptosporidium spp [34%], Sarcocystis spp [6%], Trichomonas spp [4%]. A total of 95% of the turkeys were infected, with majority of the birds having mixed infection. Interestingly, none of the turkeys examined was infected with trematodes. There was no statistically significant difference in prevalence [p>0.05] among the Turkeys. There was difference [p<0.05] in the prevalence of infected male and female turkeys. The females had higher Infestation with the parasites than the males. There was no significant difference [p>0.05] among the age groups. The prevalence of gastrointestinal parasites in this study shows a higher occurrence in exotic breed of turkeys 58.9% when compared to the local breed 41.1%. The domestic turkeys raised are hosts of a great number of gastrointestinal parasites which is attributed to the production system to which they belong. Therefore, Turkeys raised in free range condition of breeding should have a boundary and food served to them to reduce their search for food which exposes them to intermediate hosts of parasites.
Learning-Type Anchors-Driven Pose Estimation for the Autolanding Fixed-Wing UAVs
Authors: Tang Dengqing , Shen Lincheng , Xiang Xiaojiao , Zhou Han , Hu Tianjiang
Published: November 2021

We propose a learning-type anchors-driven real-time pose estimation
method for the autolanding fixed-wing unmanned aerial vehicle (UAV). The
proposed method enables online tracking of both position and attitude by the
ground stereo vision system in the Global Navigation Satellite System denied
environments. A pipeline of convolutional neural network (CNN)-based UAV
anchors detection and anchors-driven UAV pose estimation are employed. To realize robust and accurate anchors
detection, we design and implement a Block-CNN architecture to reduce the
impact of the outliers. With the basis of the anchors, monocular and stereo
vision-based filters are established to update the UAV position and attitude.
To expand the training dataset without extra outdoor experiments, we develop a
parallel system containing the outdoor and simulated systems with the same
configuration. Simulated and outdoor experiments are performed to demonstrate
the remarkable pose estimation accuracy improvement compared with the
conventional Perspective-N-Points solution. In addition, the experiments also
validate the feasibility of the proposed architecture and algorithm in terms of
the accuracy and real-time capability requirements for fixed-wing autolanding
UAVs.
Wearable Motion Capture: Reconstructing and Predicting 3D Human Poses from Wearable Sensors
Authors: Moniruzzaman Md , Yin Zhaozheng , Hossain Md Sanzid Bin , Guo Zhishan , Choi Hwan
Published: November 2021

Identifying 3D human walking poses in unconstrained environments has many applications such as enabling prosthetists and clinicians to access the amputees’ walking functions outside clinics and helping amputees obtain an optimal walking condition with predictive control. Thus, we propose the wearable motion capture problem of reconstructing and predicting 3D human poses from the wearable IMU sensors and wearable cameras. To solve this challenging problem, we introduce a novel Attention-Oriented Recurrent Neural Network (AttRNet) that contains a sensor-wise attention-oriented recurrent encoder, a reconstruction module, and a dynamic temporal attention-oriented recurrent decoder, to reconstruct the current pose and predict the future poses. To evaluate our approach, we collected a new WearableMotionCapture dataset using wearable IMUs and wearable video cameras, along with the musculoskeletal joint angle ground truth. The proposed AttRNet shows high accuracy on theWearableMotionCapture dataset, and it also outperforms the current best methods on two public pose prediction datasets with IMU-only data: DIP-IMU and TotalCaputre. The source codes and the new dataset will be publicly available on https://github.com/MoniruzzamanMd/Wearable-Motion-Capture.

Algae is a phototrophic organism and is the primary and main food source of organic matter. They can originate organic matter from inorganic substances such as, dry plants. In the process of photosynthesis, they release O2 and absorb CO2 and make it possible for the entire marine animal population. Macrophytobenthos plays a crutial role in the coastal ecosystem of the Caspian Sea. Macrophytes and seaweed provide a sustainable flow of organic matter to heterotrophic organisms and create a plant biotope for invertebrates and phytophilic fish. The dynamics of aquatic vegetation mainly determines changes in benthic communities, their distribution and resources. The level of the Caspian Sea and its salinity determine the distribution of aquatic plants, phytobenthos and of course fluctuations and changes in the level of the Caspian Sea play an important role in the dynamics of aquatic vegetation.

An Empirical Study of Multidimensional Poverty and Influencing Factors in Western China
Authors: Zhang Li
Published: November 2021

In the post-poverty alleviation period, the focus of China’s poverty alleviation work has also shifted from single-dimensional poverty to multi-dimensional poverty. This study uses panel data from the western region from 2014 to 2019, uses the entropy method to calculate the multi-dimensional poverty index, constructs an econometric model, and uses Stata software to conduct an empirical analysis of the multi-dimensional poverty influencing factors in the western region. The research results show that regional differences are one of the important factors affecting multi-dimensional poverty, and e-commerce participation has an important impact on the alleviation of multi-dimensional poverty. To this end, this article puts forward suggestions for increasing financial investment, cultivating core talents, paying attention to regional differences, and supporting poverty alleviation industries.
Factors That Matter for Financial Inclusion: Evidence from Sub-Sharan Africa - The Zimbabwe Case
Authors: Mhlanga David
Published: November 2021

The study intended to investigate the factors that are important in influencing the financial inclusion of smallholder farming households in Sub-Saharan Africa with a specific focus on Zimbabwe. Motivated by the fact that there is an increase in the evidence of the importance of financial inclusion in fighting poverty and the fact that by merely having a bank account, financial inclusion cannot be guaranteed, the study went further to interrogate factors that influence smallholder farmers to have a transaction account, to borrow and to have insurance. Since the dependent variable of financial inclusion had more than two categories, with three unordered categories, transaction account, savings/credit account, and insurance, the multinomial logistic regression was used to estimate the determinants of financial inclusion from these three categories of the dependent variable. The multinomial logit model results, with insurance as the reference category, indicated that the size of the household, transaction costs, gender and agricultural extension service were the factors influencing the demand for a household to open a transaction account. On the other hand, off-farm income and age of the household were the only two factors significantly influencing households to borrow. Therefore, it is imperative for, the government of Zimbabwe to come up with more policies that encourage farmers to participate in the formal financial market as financial inclusion can help to fight poverty and the general developments of societies.

Strategies for the Development and Application of Research Frameworks in Sciences Education Research
Authors: Mnguni Lindelani
Published: November 2021

Recent research in social sciences and education shows that a significant number of studies are neither reproducible nor repeatable. This compromises the validity, reliability and trustworthiness of these studies, as they violate the prescriptions of the nature of science. This lack of validity, reliability and trustworthiness could be due to poorly conceptualized research frameworks, including the conceptual framework and theoretical framework. Additionally, there is an apparent confusion on the difference between the research frameworks and their role in research. The current paper defines the different research frameworks that are used in science education. It also provides systematic strategies for the development and application of research frameworks in science education research. By using these systematic strategies, researchers could enhance the validity, reliability and trustworthiness of their research.

The Urgency of Political Commitment in Formulation Reproductive Health Education Policy
Authors: Christine Margareth , Paskarina Caroline
Published: November 2021

Kulon Progo is the first area to have a local content of Reproductive Health Education in the curriculum, that is, since 2014. This was motivated by the high rate of underage marriage and the high level of maternal mortality ratio in the Special Region of Yogyakarta at that time. The Regent of Kulon Progo who served during that period, Hasto Wardoyo, was the party who initiated and directly led this policy-making process. This study seeks to analyze the form of political commitment from Hasto Wardoyo in the policy on Public Health Education by using Boli’s theory of political will criteria, in which political commitment is broadly divided into three groups, namely verbal will, institutional will, and budgetary will. Researchers used qualitative research methods supported by interview data with parties directly involved in the process of making and implementing policies, including the Chair of the Indonesia Union of Teachers, the Chair of the Indonesia Association of Family Planning, the Head of the Education Office, and the Head of the Health Office in the regency. The results of this study indicate that the Regent has shown his political commitment in the sense of verbal and regulation dimensions. However, in terms of institutional and budgetary will, the Regent did not show any form of political commitment, which resulted in the neglect of this policy on Reproductive Health Education after it had been launched.

Immigrant Parents' Voices on Children's Right to Education in South African Schools: Connecting the Disconnected
Authors: Nylon Marishane RN
Published: November 2021

This paper focuses on the school's protection of the right to education for immigrant learners as perceived by their parents.  With its approach to the subject from the human rights-based educational perspective, this paper sought to examine immigrant parents' views on their children's right to education against their background as vulnerable and marginalised school community members. The assumption on which the study presented in this paper is based is that meaningful discussion on the right to education for immigrant learners cannot be disconnected from the challenges their parents face in educating them. Immigrant parents have their views and experiences relating to children's educational rights, which are seldom studied. Guided by this view, a qualitative approach was followed to gather data through semi-structured individual interviews held with parents of immigrant learners from four purposively selected South African township schools. The results show that immigrant parents experience enormous challenges in the education of their children in South African schools. While some of the challenges are transferred from them to their children because of non-citizenship, they attribute most of the challenges to people who teach their children, namely, teachers.

Authors: Rachmawati Iva , Kurniawati Erna , Anggraini Melaty
Published: November 2021

This study aims to find the right strategy for increasing scientific publications for students of the Department of International Relations, UPN 'Veteran' Yogyakarta, Indonesia. Thus, it is essential to consider the low number of scientific publications produced by students considering that scientific publications are an obligation for academics. The Director-General of Higher Education Letter No. 152/E/T/2012 concerning the duty of scientific publications for students and Regulation of the National Accreditation Board for Higher Education Number 5 of 2019 concerning Study Program Accreditation Instruments requires publication and citation student scientific articles. The research uses action research to find strategies for increasing scientific publications where there are three research steps: identifying problems, making and testing procedures, and evaluating. The second step is to try the strategy based on problem identification. Problem identification is made through an online open questionnaire. The third step is the evaluation of the action research. Experiments conducted to influence student behavior in scientific writing showed that socialization and coaching clinics were needed to increase knowledge about scientific writing and encourage ideas. While writing assistance can produce student scientific publications because of its nature and able to foster comfort. This empirical evidence provides insights for the manager of student scientific journals and department managers to provide formulations for improving students' quality and quantity of scientific publications.

Authors: Hernández Ronald M. , Cabrera-Orozco Isabel , Esteban Renzo Felipe Carranza , Mamani-Benito Oscar , Chaparro Josué Edison Turpo
Published: November 2021

This research aimed to characterize the Latin American scientific literature production on burnout between 2010 and 2020. A descriptive study was carried out with Latin American publications in journals indexed in the Scopus database as the unit of analysis. The variables studied were document frequency, scientific production by country, number of authors, institutional affiliation and scientific production by descriptor on burnout. The documentary type that appears the most is research papers with 85.03%. Out of a total of 154 authors affiliated to 163 Latin American institutions, the trend of scientific production by country shows that Brazil leads with 52.51% of the production in Latin America. The journals with the largest production were Revista da Escola de Enfermagem (n= 8), Revista Brasileira de Medicina do Trabalho and Revista Latino Americana de Enfermagem, with 22 documents each. Scientific production studies on an area of knowledge guide the research work. Thus, knowing what publications have been made on burnout will allow us to establish a Latin American research policy that will benefit the psychological discipline. However, it is necessary to increase the number of studies on burnout in Latin America in order to consolidate authorship collaboration and the literature on the subject.

Published: November 2021

Serious concerns have been raised by many stakeholders in environmental issues including Cross River State Government, educationists, non-governmental organisations and even, the international funding agencies, about the quality and level of environmental information that can be accessed in both print and electronic media. This has become imperative because proper understanding of the origin of the present environmental challenges is the key to minimise the on-going abuses in future. This study was undertaken to investigate the level of environmental awareness issues contained in comprehensive passages present in English Language textbooks used by Junior Secondary School students in Cross River State, Nigeria. The study involves counting and analysing the number of passages dealing with environmental issues in 27 textbooks based on the four types of environments: abiotic, biotic, neutral and social. Two research questions were formulated and used to guide the study. Observed data were analysed using simple percentage technique. Results show that issues concerning the environment were reflected in all the textbooks but sometimes in an undesirable proportion. It was concluded that the practice of emphasising social and abiotic environments issues at the detriment of others do not auger well for proper development and impartation of environmental awareness to students.

Companies and the Constitutional ‘Right to Life’: A Critical Analysis of the Companies Act 71 of 2008
Authors: Phiri Siphethile
Published: November 2021

Corporate law is founded on the fictitious principle of the separate legal personality of a company. This principle entails that a company is a juristic person, separate and distinct from any persons involved with the company. Because of their juristic nature, companies can acquire rights and incur liabilities in their own capacity. This corporate-law principle is rooted in section 8(4) of the Constitution of the Republic of South Africa, 1996 (hereafter the Constitution) which expressly provides the Bill of Rights applies to juristic persons subject to the stated considerations. The fact that companies as juristic persons, similar to natural persons, are entitled to the rights and freedoms contained in the Bill of Rights reveals that the Constitution recognises companies as ‘persons’. In this light, the article investigates how the Companies Act 71 of 2008 (hereafter the Companies Act) has embraced the constitutional right to life of companies as juristic persons as provided for in section 11 of the Constitution. To achieve this aim, the author applies the doctrinal legal research methodology – a legal research model which entails an examination of so-called ‘black-latter law’ with the Companies Act being the principal instrument. The results show that, although companies to do not enjoy the right to life in the same manner as natural persons, the literature examined reveals that the Companies Act recognises company’s constitutional right to ‘life’. In many instances, the right to continued existence of companies is promoted in various ways, including the introduction of the novel concept of business rescue by the Companies Act as a way of promoting the right to ‘life’ of companies.

Results: A total of 500 patients were included in the study. 78 patients(16%) were diagnosed as Osteoarthritis,124 patients as Fibromyalgia(25%),212 patients as Spondyloarthropathy(42%), 42 cases as Low back pain (9%), 12 cases of fracture(2%), rest 32 cases(6%) was categorised as others..Among 212 patients diagnosed as spondyloarthropathy 180 patients (89.90%) had Vitamin D deficiency, 98 patients out of 124 patients(79.03%) diagnosed as Fibromyalgia were having Vit D deficiency.
Conclusion: The findings of this retrospective study suggest a significant association between Vitamin D deficiency and specific chronic pain conditions. These results underscore the importance of evaluating and addressing Vitamin D levels in patients with chronic pain, which may potentially improve pain management and overall quality of life.
MEDIEVAL FLANGED TILES FROM THE SOUTH-WESTERN CRIMEA: PROBLEMS OF PRODUCTION LOCALIZATION, TYPOLOGY AND CHRONOLOGY
Authors: Moiseiev D. A.
Published: November 2021

This text is about the problem of typology, localization of the producing and dating of medieval building ceramics (Flanged tiles) of the South-Western Crimea. The investigation of products of tile production centers in the South-Western Crimea allowed to systematize a large complex of archaeological sources. They came from various archeological sites that were located throughout the region. Technological and morphological typology allowed to arrange and dating all this complexes and different material in some cases with an accuracy of up to two decades. The unified technological and morphological description and typology of the material described development and evolution of tile production craft in the South-Western Crimea trough the Medieval time. Therefore, this work could be a variant of a unified field guide for medieval Flanged tiles from Crimean sites and a chronological chart for them.

The Lower Dniester (Snake) Defensive rampart on the border of the Roman Empire is one of the largest and most significant objects of the ancient Roman fortification of the Northern Ponticregion but at the same time the most controversial and least known not only to general public but to professional historiansas well. Over the last decade, based on a detailed study of cartographic sources and materials of numerous archaeological surveys it has been possible to reconstruct completely the line of this rampart which turned out to be the longest of all earthen ramparts in Budzhak or Bessarabia (Sapozhnikov 2011; 2013; 2020a). This paper is devoted to such components of this unique monument of military architecture and engineering as topography and archaeology as well as relative and absolute dating both by traditional methods and by the method of soil-genetic chronology.

Today we can say that the rampart runs on the right bank of the Dniester from the Sergeevka village near the Black Sea to the right bank of the river Botna near the Plop-Stubei village for 123—125 km, and the total length of this structure (with additional fortifications and protection of the camps) reached 134—136 km. Since the rampart lies on the Late Scythiansettlements Mologa II and Vesele III its terminus post quem can be defined as the early 3rd century AD. Terminus ante quem according to soil-chronological studies by F. N. Lisetsky is limited to the second half of the 3rd century AD. Based on the historical situation in Tyras and its environs during this period the authors concluded that such a significant structure was built by the Romans (or the local population under their leadership) in the first half of the 3rd century AD.
TRACES OF THE ANCIENT PATHS IN THE STEPPE TAVRIA

The original appearance of the steppe surface of the southern part of the eastern European plane was transformed by the centuries of the anthropogenic impact. Along with feather grass the traces of the ancient roads have disappeared. However, the satellite images still detect the areas around some kurhans having kept the waggons traces. We can recognize them due to the different color of vegetation as well as by the coloration of the open soil. The antiquity of the roads near kurhans is witnessed by the cases of tracks, covered by the burial mounds, that were erected in the Bronze Age. An additional indicator of the ancient transport network on the maps of the 19th century are wells or groups of pits in the open steppe, the number of which should be associated with the need to water a large number of cattle. The latter occurred during the arrival of a trade caravan or a train of wagons. The kurhans themselves are an ancient form of mass cult buildings in the Eurasian steppe, which have attracted both large main and secondary roads. Powerful tradition of building kurhans, fading and restoring through times, existed from the Eneolithic to the late Middle Ages. The appearance of new mounds or the completion of existing ones periodically renewed the system of landmarks in the monotonous steppe.

The paper provides an overview of previously unknown megastructures near the Scythian giant kurhans of Oguz and Chortomlyk, which in the form of light parallel stripes are recorded on satellite images. These stripes are probably traces of trenches or the foot of stone alleys, that were found to the east of the edge of the Oguz and outreached 800—850 m, and from Chortomlyk — 670 m. A search on various satellite images of the similar light stripes near other kurhans did not yield positive results. However, in the central part of the Dnieper-Molocha steppe region, satellite images luckily detected 19 nodes (intersections) of ancient ways connected to the kurhans’ mounds. Some of these nodes do yet not fit the complete road network of the region. But six of these nodes appear to be in the area of the route of the ancient path, known in the Middle Ages as Muravsky (Murava Route). It leaded from the Don basin, through the left (eastern) part of the basin of the Dnipro River to Crimea through the Isthmus of Perekop. Interestingly, this branch of the Muravsky Trail crosses the Sirogozy ravine between the kurhans of Kozel and Oguz. In previous reconstructions of the transport network, the option of passing this branch in the south of the Oguz, between the giant embankment and Diyiv kurhan, was preferred. The other three intersections lie in the lane of the old Chumaks’ Way or the Crimean Way, marking a forty-kilometer section between kurhans Kozel and Velyka Tsymbalka. From the center of the Tavria Steppe at least four directions of paths emerge towards the ancient Dnipro fords-crossings: Rogachytsia, Lepetych, Cair (Nosakiv) and Kіzikermen (Tavan).
«THE HEADLESS HORSEMAN». THE SKYTHIAN GRAVE IN THE BARROW NEAR KUSTORIVKA VILLAGE

In 2013 near Kustorivka village of Krasnokutsky district, Kharkov region the Scythian burial mound (5th—4th centuries BC.) was excavated. The inserted burial of a beheaded man has been discovered there. Fragments of horse bones, horse harness, numerous arrowheads, the spearhead and knife were unearthed in the grave. Funeral inventory dates the burial to the 2nd half or the end of 5th — the early 4th century BC.

The grave goods allowed us to suggest that the man was a horseman and possessed a bow with arrows, javelin or lance. These assumptions have been confirmed by anthropological studies of the development of muscles relief, injuries and specific skeletal markers. The skeleton showed clear signs of a horseman’ and archer’ osteological complexes.

The man died at the age of 20—25. The skull, first and second cervical vertebrae were absent in the undisturbed burial. The upper part of the left intervertebral condyle of the 3rd vertebra was cut off by the hit from left behind and below. These signs are evidence of decapitation. In addition, numerous cut marks made with a sharp blade were found on the anterior and lateral surfaces of the 3rd and 4th cervical vertebrae, as well as on the left femur above the knee. Thus could be the signs of the body cleaning of waste tissue for its transportation or in course of the preparation for the burial.

Studies of the horse’s remains showed that it has deceased at the age of 10—12 years. The horse was decapitated as well by the hit directed between first and second cervical vertebra. The head was also cut in half and only one part of it was present in the burial. There were also some bones of the animal’s skeleton, which do not belong to the edible parts of the body. The severed head of the horse was located above the place where the man’s head was supposed to be, thus the horse harness was situated on the level of the human skeleton.

Traces of the possible preparation of the human body for burial and the location of the remains of a horse over a lost human head along with other changes in the skeleton indicate a certain funeral rite, direct analogies of which have not yet been found in the North Pontic region.

Abstract. The problem of early diagnosis and treatment of orphan (rare) diseases is unresolved in the world medical community. This is mainly due to the fact that some of this cohort of diseases have an incidence of less than 1:1,000,000. In most cases, the diagnosis is made after the height of the disease and quite often in the presence of irreversible changes. Department of Psychoneurology, State Institution «Institute of Pediatrics, Obstetrics and Gynecology named after acad. O. M. Lukyanova of the NAMS of Ukraine» has been engaged in the diagnosis and treatment of orphan diseases since 2012 and has experience in the diagnosis and treatment of orphan diseases, 80 % of which are manifested by neurological symptoms. A large number of orphan diseases in children occur under the clinical «masks» of diseases such as cerebral palsy, hydrocephalus, epilepsy, mental retardation and autism spectrum disorders. It is important that the pediatrician be vigilant about orphan diseases and approach the diagnosis from the etiology and pathogenesis of development, rather than clinical manifestations. In recent years, doctors have armed themselves with modern diagnostic techniques such as MRI, MR spectroscopy, next generation sequencing (NGS), whole exome sequencing (WES), and whole genome sequencing (WGS). But the question remains about the interpretation of the results obtained, the algorithm for early diagnosis and the patient's clinical route. In this publication, we would like to share our experience in the diagnosis and treatment of orphan diseases, taking into account modern protocols and data based on our own observations and international scientific sources. We give an example of a rare (orphan) disease caused by a POLG mutation and describe the entire diagnostic process from the appearance of the first symptoms of the disease to the establishment of the final diagnosis Keywords: orphan diseases, perinatal neurology, mitochondrial diseases, leukodystrophies, complete exome sequencing
