Effects of the alumina reinforcement ratio on the corrosion properties of iron based composite materials
Authors: Karacif Kubilay
Published: November 2020

Iron based composite materials reinforced with various ceramic particles are used in operating conditions requiring features such as high hardness, strength and wear resistance. The composite materials may be subject to corrosion depending on the working environment. In this study, the corrosion properties of iron based composite materials produced by powder metallurgy, containing carbon and different amounts of alumina reinforcement were investigated. In the materials production, 0.5 wt.-% carbon and 1, 3 and 5 wt.-% alumina powders were added to the iron powders as reinforcement. Followed by mixing, one-way cold pressing and sintering, respectively, both iron based carbon and alumina reinforced composite samples were obtained. The electrochemical corrosion properties of iron based composite materials containing various amounts of alumina reinforcement were investigated in a 3.5 wt.-% NaCl environment and the effects of the reinforcing material ratio on the corrosion behavior of the composite material were determined. It was determined that with an increase in the alumina reinforcement ratio, the corrosion rate of the material increases and the corrosion resistance decreases.

Published: November 2020

Hollow shafts are typically deployed in real world engineering application where strength to density ratio is highly desirable. Introduction of cutouts will also assist in achieving the same, where further material reduction is inevitable. This research work mainly focusses on assessing the impact of introducing cutouts on a hollow shaft system experimentally, followed by numerical validation. In this study the vibrational characteristics of a hollow shaft made up of linear elastic material is compared with a composite one for five different geometric profiles. Obtained results clearly reveal that introduction of cutouts and composite material significantly reduces the natural frequency of the system. Also, the experimental results are well in line with the values derived from the finite element method.

Hydroxychavicol (HC) is a phenolic compound of betel leaf (Piper betle). It has been reported to have antifungal properties against dermatophytes including T. rubrum. The aim of this study was to identify the effects of the HC against T. rubrum. Broth dilution method was used to determine the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) of the HC. Microscopic study of the treated fungus was done by transmission electron microscope (TEM). Cytotoxicity study using pre-adipocyte (3T3-L1) cell line was performed by means of MTT cell proliferation assay. The MIC and MFC results of the HC were both 0.49 µg/ml. Microscopic study revealed the destruction of the fungal cell wall and organelles. Cytotoxicity study showed HC to be non-toxic to the tested human cell line. In conclusion, HC may potentially be used as an alternative therapeutic agent against T. rubrum infections.
Methemoglobinemia – Two Uncommon Presentations
Authors: Gundogdu Zuhal , Ipekçi Belkıs , Çınar Bengu
Published: November 2020

Two rather different cases of methemoglobinemia are presented. The first case is an infant who had a circumcision procedure with prilocaine. The second case involves a 14-year-old girl who attempted suicide with an overdose of metoclopramide and butamirate citrate. The attention is drawn to differences in hospital admission and management especially with respect to methemoglobin level and age. If methemoglobin levels reach ≥ 10%, cyanosis would appear first. Symptoms of hypoxemia and diminished oxygen transport do not develop until levels reach 30 to 40%. Not only early intervention is crucial but also patients should not be discharged from the hospital too soon. Doctors should be able to identify high risk patients, paying a special attention to infants younger than three months old who might be at an increased risk of methemoglobinemia which is a potentially lethal complication of prilocaine. As for our second case, methemoglobin level has not increased, despite an overdose of metoclopramide. This may be due to age or timely elimination of toxic agents by gastric lavage, catharsis and administration of procyclidine.

Published: November 2020

Background: Hereditary nonpolyposis colorectal cancer (HNPCC) also known as Lynch syndrome is commonly caused by genetic alterations in any of the four mismatch repair (MMR) genes; MLH1, MSH2, MSH6 and PMS2. This is the first study aimed to investigate genetic variants in Malay HNPCC families. Methods: Six Malay HNPCC families who fulfilled any of the Bethesda criteria were recruited into this study. A total of 3 ml of blood was withdrawn from each patient in the families. The samples were further analyzed using polymerase chain reaction and direct sequencing of the selected exons of MLH1 and MSH2 genes. Results: Two missense mutations and four single nucleotide polymorphisms (SNPs) were identified in six patients. These variants in the MLH1 and MSH2 genes were identified in four families who met the revised Bethesda guidelines. In two families, no mutation and polymorphism was identified in both the exon and intron of the respective genes. Of the mutations and polymorphisms identified, five have never been reported in Malay HNPCC families before. A missense mutation was detected in exon 5 of the MLH1 gene, c.394G>C (p.Asp132His) and four mutations and polymorphisms were detected in the MSH2 gene; heterozygous c.211+98T>C and c.211+9C>G and homozygous c.211+98T>C and c.211+9C>G, c.367-86A>C and c.382C>G. Conclusion: The results represented a new spectrum of mutations and polymorphisms in the Malay HNPCC families. However, a larger study involving additional families and analysis is required to determine the impact and nature of the identified mutations and polymorphisms.

Published: November 2020

Introduction: Dorsalis pedis artery (DPA) is the chief artery that supplies the dorsum of the foot. Palpation of DPA at the dorsum of the foot is important in case of atherosclerotic disease. A sound knowledge of DPA like its branching pattern is essential for the ankle surgeries as well as its presence or absence in case of peripheral vascular disease. Material and methods: 30 Lower limbs of unknown age and sex were dissected in the department of Anatomy, Kasturba Medical College, Manipal. The skin and fascia were removed.The measurement of Dorsalis pedis artery till its termination, Length from medial malleolus, Length from lateral malleolus and branching pattern of Dorsalis pedis artery was studied. Results: In this study, the average length of dorsalis pedis artery was found 7.8cm, average length from medial malleolus was 3.9cm and average length from lateral malleolus was 4.5cm.The normal branching pattern of medial tarsal artery was noticed in 53% and lateral tarsal artery in 63% cases. The arcuate artery was absent in 3% of cases. Conclusion: The knowledge of the variation of DPA is helpful during various foot surgeries. Knowledge of the variation will be useful in deciding whether the absence of the pulse in DPA is due to thrombosis of the vessel or its abnormal course or absence. DPA does not always lie at mid -malleolar point.

Catheter-related bloodstream infections caused by Kodamaea ohmeri are generally not considered due to the relative scarcity of reported cases. This is a case of an 85-year-old man with poorly controlled diabetes mellitus who was initially admitted to our hospital for diabetic ketoacidosis. An internal jugular catheter was inserted as part of the initial management. A week later the patient developed a temperature spike and a yeast identified as Kodamaea ohmeri by ID 32 C (bioMérieux, France) was isolated from both his central and peripheral blood cultures. The catheter was removed and the patient was treated with fluconazole despite the organism’s relatively high minimum inhibitory concentration (2 μg/mL) to this antifungal. The fungemia resolved following a 2-weeks course of fluconazole.

Introduction: Non-pharmacological interventions are considered as successful adjuncts to manage pain. We are studying the comparative effects of listening to prayer recitation and music therapy intraoperatively as non-pharmacological interventions on postoperative pain and intraoperative haemodynamics. Materials and Methods: Seventy two muslim patients with acute appendicitis requiring open, emergency appendicectomies under general anaesthesia were recruited and randomised into three groups: Group A: patients who listened to prayer recitation, Group B: patients who listened to music, Group C: control group - patients who did not listen to any prayer or music. Intraoperative blood pressure, heart rate and postoperative pain scores were monitored. Results: The demographic data, pre- and post-headphones application haemodynamics were compared. There were significantly lower heart rates at 10, 20, 30, 40, 50, 60 minutes for Group A and at 50 and 60 minutes for Group B patients when compared to Group C. Significant reduction in postoperative pain scores were seen in Group A patients at 30 minutes and 8 hours as compared to Group C patients. No significant differences in pain scores were seen between Group B and C patients. No significant differences in additional analgesic requirements postoperatively were seen in all three groups. Conclusion: Listening to prayer recitation or music intraoperatively significantly lowered intraoperative heart rates, however only prayer recitation significantly reduced postoperative pain scores as compared to the control group.

Published: November 2020

Introduction: Post-menopausal osteoporosis is the most common type of osteoporosis, which occurs due to a deficiency of oestrogen following menopause. Considering the adverse effects of oestrogen replacement therapy, natural products may serve to replace the current conventional treatment. Ficus carica (FC) which is commonly known as fig may have a potential in treating post-menopausal osteoporosis due to their abundance of important minerals and bioactive compounds such as phenolic, flavonoid and anthocyanins. This study aimed to evaluate the effects of FC on bone metabolism of ovariectomized rats. Materials and Methods: Fifty-six female Spraque-Dawley rats were randomly divided into seven groups; SHAM operated (SHAM), ovariectomized control (OVX), ovariectomized + 64.5 µg/kg oestrogen (ERT), ovariectomized + 50 mg/kg aqueous extract of FC (AQ50), ovariectomized + 100 mg/kg aqueous extract of FC (AQ100), ovariectomized + 50 mg/kg raw FC (RW50), and ovariectomized + 100 mg/kg raw FC (RW100). After eight weeks of treatments, rats were euthanized and femurs were dissected out to measure bone osteocalcin, Ctelopeptide of type 1 collagen and bone estrogen level. Results: RW50 and RW100 showed an increasing trend in osteocalcin levels and also oestrogen level, but no significant difference between all groups. RW50 and RW100 also showed significantly reduced C-telopeptide of type 1 collagen levels compared to OVX group. Conclusion: These findings suggested that raw FC at the doses of 50 mg/kg and 100 mg/kg have potential to improve bone in treating post-menopausal osteoporosis. However, this need to be confirmed with higher doses.

Published: November 2020

Introduction: To date there are five reports referring to cholesterol granuloma of the sphenoid sinus. This
is the first case where cholesterol granuloma is presented as a late complication after successful removal of
a mucocele through functional endoscopic sinus surgery (FESS) and associated with convergence
insufficiency.
Case Report: A 67-year-old carpenter presented with binocular diplopia and frontal headache. A mucocele
of the left sphenoid sinus was removed endoscopically leading to the resolution of his symptoms. Eight
months later he presented with similar symptoms and findings. Following a revision FESS, cholesterol
granuloma was diagnosed.
Discussion: Haemorrhage within the sphenoid sinus, obstruction in the sinus ostium and fibrous tissue
formation may explain the postoperative formation of cholesterol granuloma. Convergence insufficiency
could be attributed to mechanical failure or denervation of eye muscles.
Conclusion: Cholesterol granuloma should be included in the differential diagnosis, when recurrence of a
sphenoid sinus mucocele is suspected.

Published: November 2020

This study aims to design and create a virtual chemical textile laboratory model as an effort to improve students' understanding of learning Textile Chemistry, especially on the subject of making cellulose-based regenerative textile fibers that have a high level of abstraction and complexity. Theoretical learning in the form of verbal symbols, empirically is not representative enough to explain the concept of the system that is needed, so that the possibility is not affordable (likely to inaccessible) by students which effected to the lessen of learning experiences. These conditions have implications for the lack of student understanding of these processes which is indicated by the acquisition of low learning outcomes. The specific target of this research is to produce a virtual laboratory device as a simulation medium for learning textile chemistry on the subject of making effective cellulose-based regenerative fibers. Furthermore, the model developed is validated to get input from experts related to the technology used, design and process content in the developed model. The validation results show that this model is suitable for use in the study of textile chemistry and can be used to improve students' understanding of the material for making cellulose-based regenerative textile fibers. In the limited trials that have been carried out, there are some features, image choices, and some simulations that need to be refined to avoid students' misinterpretations of the planned chemical process concept. Students involved in the trials are more motivated to continue learning related concepts that have been learned. In subsequent studies this model will be tested on a broader scale to measure its effect on the mastery of concepts and its ability to improve learning outcomes in textile chemistry courses, on the material for making cellulose-based regenerative fibers.

Word Embedding Based on Large-Scale Web Corpora as a Powerful Lexicographic Tool
Authors: Garabík Radovan
Published: November 2020

The Aranea Project offers a set of comparable corpora for two dozens of (mostly European) languages providing a convenient dataset for nLP applications that require training on large amounts of data. The article presents word embedding models trained on the Aranea corpora and an online interface to query the models and visualize the results. The implementation is aimed towards lexicographic use but can be also useful in other fields of linguistic study since the vector space is a plausible model of semantic space of word meanings. Three different models are available – one for a combination of part of speech and lemma, one for raw word forms, and one based on fastText algorithm uses subword vectors and is not limited to whole or known words in finding their semantic relations. The article is describing the interface and major modes of its functionality; it does not try to perform detailed linguistic analysis of presented examples.

The purpose of the article is to justify the concept of reorienting irrevocable budget allocations to a rotary, but preferential lending to producers of agricultural sector of Ukraine. Research methods. The following scientific methods is used: formalization, deduction, inductive and abstract-logical – for the analytical processing of scientific sources, which highlight the achievements of scientists in the light of the indicated problem; economic and mathematical – to establish a causal relationship and trends of the studied factors; statistical comparison and grouping – to determine the dynamics of the studied indicators over a long period; logical generalization – to formulate conclusions on the results of a study of the problem of improving financial and economic relations in the agricultural sector of Ukraine; graphic – for visualization of factual material. Research results. Given the fact that the volume of budgetary subsidies for producers of the agricultural sector of Ukraine is insufficient, and their traditional irrevocability does not prompt searches for domestic reserves, but dependent moods, therefore they do not have a tangible effect on development in farms that manage to get them as a result of unweighted selection of recipients – not always those who use these subsidies rationally, the concept of reorienting irrevocable budget allocations to a rotary, but preferential lending to agricultural producers is justified. Scientific novelty. The concept of reorienting irrevocable budget allocations to a rotary, but preferential lending to agricultural producers is justified for the first time, therefore, it has elements of scientific novelty. Practical significance. The area of implementation of the measures proposed in the article may be the sphere of financial and economic relations in the agricultural sector of Ukraine. Tabl.: 1.

The purpose of the article is to investigate the initiation, current issues, and further development of agricultural advisory services in Ukraine. Research methods. The research uses dialectical methods of cognition and monographic method (for the analysis of legislation, works of Ukrainian and foreign scientists on the problem of advisory services in agriculture), empirical and graphical methods (to assess and demonstrate the structure of organizational forms and marketing methods of advisory services), abstract logical methods (for theoretical generalizations and formulation of conclusions). Research results. The study has highlighted that agricultural advisory services institution is a powerful tool to help smallholders in Ukraine break the cycle of low productivity, vulnerability, and poverty. By providing farmers with knowledge and tools about modern agricultural practices, agricultural advisory services can be a critical force for change. However, the development of these organizations in Ukraine now meets such challenges as low level of governmental support for agriculture advisory activities, understaffing of agricultural advisory services, and confusing mechanisms of cooperation with formal institutions for agricultural advisory services organizations in Ukraine etc. Scientific novelty. This study has investigated the current perspectives and challenges of agricultural advisory services in Ukraine. It has highlighted perspective points of development and improvement for such organizations to support further rural development in Ukraine. In particular, governmental development programs to promote the agricultural advisory activities for both rural smallholder farmers and local authorities, creating the mechanisms of cooperation between agricultural advisory service organizations and formal institutions in Ukraine, support of professional development for advisors and experts, etc. Practical significance. Summarising the achieved and analysed data, scientists and policymakers to develop the support programs for agricultural advisory service organizations to support rural smallholder businesses and to improve the living standards of rural communities may use the results of the study.

The purpose of the article is to characterize the organizational and structural aspects of the formation of economic efficiency of agricultural enterprises. Research methods. General scientific methods were used during the research - analysis and synthesis (to identify the links between the factors of formation of economic efficiency of agricultural enterprises, as well as to assess the status unifying effects of its formation); induction (for the implementation of theoretical conclusions about the patterns of causation of organizational and structural changes and the results of economic activity of enterprises); comparison (to compare the dynamics of changes in the structural composition of enterprises in the process of economic reform, as well as the financial efficiency of their activities); abstract-logical method (for structuring the factors and effects of the formation of economic efficiency of agricultural enterprises). Research results. The organizational and structural aspects of the formation of economic efficiency of agricultural enterprises as a representation of their system, as well as individual businesses are substantiated and disclosed. Scientific novelty. Based on the systematization of empirical data on the development of agricultural enterprises, it was identified modern features of the formation of economic efficiency, its organizational and structural aspects with estimates of the enterprises size and their regional specifics of efficiency. Practical significance. The obtained results have an applied, methodological orientation and provide an opportunity to justify management decisions in the development of agricultural enterprises depending on the size and taking into account the organizational form.

TOXICODYNAMICS PECULIARITIES AND RISK ASSESSMENT OF NEW MICROSOMAL ENZYMES INDUCTOR FUNGICIDE SEDAXANE
Authors: Antonenko A.M.
Published: November 2020

Summary. It is known that today from crop diseases dying about a third of the crop. Furthermore, fungal toxins can cause poisoning of humans and animals. For combating these problems pesticides are widely used. One of the way of solving the problem of pest resistance to commonly used fungicides is the use of substances with a novel mechanism of action, such as a promising class of fungicides succinate dehydrogenase inhibitors. The aim of the work was hygienic risk assessment on toxicological criteria of the new fungicide inhibitor of succinate dehydrogenase II generation sedaxan, scientific substantiation of its acceptable daily intake. Assessment of toxicity to warm-blooded laboratory animals and the danger to humans was carried out by the literature and websites according to the current in Ukraine hygienic classification of pesticides by hazard (DSanPin 8.8.1.002-98). Acceptable daily dose of sedaxane for humans substantiated according to the methodology of integrated hygienic regulation of pesticides, adopted in Ukraine. The toxicodynamics peculiarities of new fungicides sedaxane were studied. It was found that in accordance with hygienic classification of pesticides it is referred to the 3rd class of hazard (moderately hazardous). It was shown that the primary target organ of sedaxane action is liver, secondary - thyroid gland. It was established that sedaxan is microsomal enzyme inducer of phenobarbital type. Acceptable daily dose for humans of sedaxane was substantiate on level of 0,1 mg/kg.
THE SIGNIFICANCE OF LIPID METABOLISM DISORDERS IN THE BLOOD AND SKIN OF PATIENTS WITH PSORIASIS IN THE PATHOGENESIS OF DERMATOSIS

Published: November 2020

Summary. The etiology of psoriasis continues to remain unsettled, and issues of the pathogenesis of this dermatosis are also not fully resolved. The analysis of lipid metabolism disorders in the blood and skin of patients with psoriasis, established at the present stage, indicates their importance in the pathogenesis of this dermatosis. At the same time, taking into account the wave-like recurrent course of psoriasis and the existence of autumn-winter, spring-summer and offseason (mixed) types of dermatosis, there remain unsolved questions of the influence of the features of lipid spectrum indexes in the body of psoriasis patients in the development of clinical exacerbations of dermatosis in different seasons of the year. Uncertainty is also the possibility of a correlation relationship between the degree and nature of imbalance in the level of the lipid spectrum in the blood and skin of patients with psoriasis with the severity of the clinical course of dermatosis. Further in-depth study of lipid metabolism in the body of patients with psoriasis involving new immunopathohistochemical techniques will contribute to the development of an improved complex individualized therapy and broadening the understanding of the pathogenesis of this dermatosis.
