Гринь О. Г., Трембач І. О. Багатокритеріальний аналіз наплавочних матеріалів для відновлення і зміцнення деталей

Аналіз літературних даних показав, що для умов експлуатації деталей машин при дії ударного навантаження основною системою легування є Fe-C-Cr-Mn, яка забезпечує високу стійкість до удару за рахунок утворення аустенітної мікроструктури з дисперсними карбідами. Перспективним є додаткове введенням рідкісноземельних металів та їх оксидів. Зроблено аналіз сучасних матеріалів та систем легування для наплавлення інструменту, що зазнає тертя металу об метал при наявності удару. Визначено оптимальну системи легування, що забезпечить підвищення зносостійкості при відновленні та зміцненні деталей, які зазнають удару з тертям металевих робочих поверхонь. На основі аналізу літературних даних обґрунтовано вибір системи легування з метою підвищення зносостійкості при відновленні та зміцненні поверхонь деталей, які зазнають ударно-абразивного зносу. Визначення оптимальної системи легування для наплавлення деталей машин з високоманганової сталі, що працюють в умовах ударно-абразивного зносу, значно спрощує завдання з розробки економно легованих наплавочних матеріалів. На основі аналізу літературних даних показано, що для умов експлуатації втомного зношування, а також при коченні/ковзанні й ударах, термічного впливу рекомендуються сплави зі структурою мартенситу та мартенситу з карбідами. Показано, що для умов експлуатації при дії ударного навантаження основною системою легування є система Fe-C-Cr-Mn, що додатково легована Mo, V, Cu, B, а для наплавленої поверхні, що зазнає тертя металу об метал  при наявності удару доцільно використовувати систему Fe-C-W-Mo-V. В обох випадках підвищення експлуатаційних властивостей металу можна досягти додатковим введенням рідкісноземельних металів та їх оксидів.

Грушко О. В., Кириця І. Ю. Критерії деформовності з врахуванням властивостей матеріалу в параметрі  напруженого стану

Немонотонність поведінки пластичності матеріалів в області додатних гідростатичних тисків залежно від класичного показника напруженого стану призводить до необхідності пошуку більш вдалих параметрів в якості аргументу діаграми пластичності. В роботі запропоновано параметр напруженого стану, який залежить від фізико-механічних властивостей матеріалу. Коефіцієнти впливу є механічними властивостями матеріалу.  Діаграму пластичності в карті металу, за допомогою введеного параметра напруженого стану, пропонується апроксимувати монотонно спадаючою експоненціальною функцією. Встановлено, що вплив головних нормальних напружень є неоднаковим щодо накопичення пошкоджень в матеріалі, який пластично деформується. Причому, даний вплив залежить від виду матеріалу, що дає можливості формування моделі пластичності, зокрема для матеріалів з різною реологією. Встановлено, що коефіцієнт впливу третього відносного головного напруження для маловуглецевих сталей, алюмінієвих та титанових сплавів становить – 0,76… 0,85.

Рекомендовано в відомих моделях деформовності застосовувати в якості аргументу діаграми пластичності запропонований нами параметр напруженого стану, оскільки фізичного змісту накопичення пошкоджень даний параметр не змінює. Область застосування того чи іншого критерію залишається у відповідності з рекомендаціями його використання в залежності від виду процесу і історії навантаження. Виконано порівняльний розрахунок використаного ресурсу пластичності за відомими критеріями та критеріями, які враховують властивості матеріалу через параметр напруженого стану. Використання діаграми пластичності, побудованої за допомогою запропонованого параметра напруженого стану, для процесів холодного пластичного деформування, які протікають в області додатного  гідростатичного тиску, залежно від виду шляху деформування та особливостей реології металу уточнює значення використаного ресурсу пластичності металу до 2-х разів, що дозволяє зменшити кількість браку виробів до 50 % для процесів, режими яких пораховані за граничними деформаціями.
Розробка методу розрахунку кривих деформування волокнистих композиційних матеріалів з металевою матрицею

Тітов В. А., Назарук Т. О. Розробка методу розрахунку кривих деформування волокнистих композиційних матеріалів з металевою матрицею

Розроблено метод побудови кривих деформування металевих композиційних матеріалів (КМ), які зміцнені безперервними круглими волокнами. Метод враховує механічні властивості структурних компонент (волокна і матриці), їх розміри та взаємне положення в КМ. Враховуючи ортотропність властивостей, метод розповсюджується на деформування волокнистих КМ в умовах лінійного навантаження (розтяг або стиск) в площинах, що перпендикулярні напрямку волокон.

Аналіз процесу деформування волокнистих КМ показує, що при деформуванні виникає суттєва нерівномірність деформацій пластичної матриці. Так, оцінка деформування КМ системи Al-B показує, що при зміні кроку волокон в межах 0,16 – 0,24 мм та діаметрі волокон 0,14 мм величина межі пропорційності композиту становить 0,12 – 0,42 від межі пропорційності матриці.

Отримані залежності, що дозволяють розраховувати криві деформування металевого композиту в пружньопластичній області на основі властивостей матеріалу матриці. Отримані криві деформування для типових КМ систем Al-B для деформацій до 0,5 – 0,6%.

Метод може бути ефективним для прогнозування пластичних властивостей при проектуванні структури  нових КМ.

Медведєв М. І., Бобух О. С., Кузьміна О. М., Самсоненко А. А. Удосконалення технології кування трубних заготовок з титанових сплавів в умовах ТОВ "Дніпропрес Сталь"

Робота присвячена удосконаленню процесу кування титанових сплавів в умовах ТОВ «Дніпропрес Сталь». При виробництві трубних заготовок з нікелевих й титанових сплавів широко застосовується кування круглих злитків діаметром 350 – 950 мм, отримуваних методом вакуумно-дугової або електронно-променевої плавки. При куванні таких зливків виникає значна нерівномірність деформації за перерізом поковки, що впливає на отримувані структуру та механічні властивості напівпродукту, що в свою чергу істотно обмежує технологічні можливості їх переробки. За попередньою технологією  кування трубної заготовки з титанового сплаву Grade 2 (вітчизняний аналог ВТ1-0) складалась з протяжки заготовки Ø 630 мм довжиною 1300-1500 мм за три виноси з проміжним підігрівом. За результатами досліджень темплетів на якість металу було виявлено, що макроструктура поковки неоднорідна за перерізом, спостерігаються зони з різною величиною зерна й різною протравленістю. Всередині поковки зерна великі, наявні виділення α-фази, з чіткою границею між зонами, що може негативно відбиватись при пресуванні, оскільки це призводить до утворення розшарувань, тріщин й плів. Для покращення структури й механічних властивостей, що забезпечують отримання бездефектних гарячопресованих труб, запропоновано удосконалити технологічний процес кування в умовах ВАТ «Дніпропрес Сталь» за рахунок зміни параметрів деформації та введення додаткових операцій. Аналіз результатів кування злитків відповідно до запропонованого режиму й металографічних досліджень якості металу трубної заготовки показав, що метал по всьому перерізу має щільну макроструктуру 5-го балу, мікроструктуру 3-го типу, твердість за Брінеллем 185 – 196 НВ, що у подальшому забезпечує бездефектне пресування передільних труб та їх наступну холодну прокатку з отриманням механічних властивостей, що відповідають вимогам нормативної документації ASTM B 338-91а «Standard Specification for Seamless and Welded Titanium and Titanium Alloy Tubes for Condensers and Heat Exchangers».

This research is conducted as simulated analysis to respond an existing issue in Indonesia's palm oil industry. In the year 2015, world consumptions for CPO has reached 37.73%, and 31.96% for soybean oil (Oil World, 2015). Compared to the condition in 1960, this is a remarkable progress, where CPO only contributed 3.18%, and soybean oil on the other hand was in the highest rank with 12.29% of the world's total vegetable oil production. This also indicates that CPO has become one of the world's strategic commodities in the world's vegetable oils market. Ever since 2008, Indonesia has been successful in surpassing Malaysia 's domineering palm oil products, and leading the world's market of vegetable oils. Indonesia's export of CPO in 2015 was predicted to reach 21.8 tons and 14.78 tons for Malaysia. This shows Indonesia's tremendous role to feed the world. Due to biodiesel mandatory policy, the demands for CPO as biodiesel fuel will be increasing, and negatively affecting Indonesia 's export growths.

Inventory is an important element in a company asset. Due to various consideration such as decreasing factor, losses, and market changes of demands, the management has to constantly do a reviews supervisions so that the funds invested to the inventory will not overly spent and so the company's operational run as it should. The vain surplus of inventory will not only weakened the liquidity health ofa company but also could be a loss and otherpotential disadvantages. Management of inventory and product takes important part of company's operational continuity. Thus, wellorganized inventory management system is stmngly advised to ensure the wellness of the company's performance. To measure the company's performance in managing the inventory, the company can use analytic ratio that includes INTO (Inventory Turnover). One of other option is using company liquidity's health analysis to see if the inventory management and sales growth affects the health of company's liquidity. The purpose of this research is to identifi and analyze the ratio of inventory management, sales growth and the health of company's liquidity with the use of INTO ratio and the sales that measured with the current ratio. This research is based on PT. Mayora Indah, Tbk, PT. Indofood Sukses Makmur, Tbk. and PT.Ultrajaya Industry & Trading Company, that market in the Food & Beverages industrialfield. This research which used analytic ratio has proven that inventory management and a positive sales growth do not give any significant influence towards company's liquidity health, because the increasing or the decreasing of inventory management and sales growth are not always followed by the increasing or the decreasing ofthe health of company's liquidity.

Peperomia pellucida (Chinese betel) is considered as a plant with antioxidant activity for  inhibiting oxidation reactions. This study aims to determine the yield of secondary metabolites, total flavonoid levels, and antioxidant activity. Dried leaves of Chinese betel were macerated using 70% ethanol as solvent. The extract was partitioned until the n-hexane and ethyl acetate fractions were obtained. A phytochemical screening test was followed by determining total flavonoid levels and antioxidant activity using UV-Vis spectrophotometry. Phytochemical screening results containing an ethanolic extract of Chinese betel leaves (ECBL) showed positive results on alkaloid, flavonoid, saponin, and tannin. Meanwhile, the ethyl acetate (EAF) and n-hexane (HF) fractions showed positive results only for flavonoid presence. The total flavonoid contents of ECBL, EAF, and HF were 3.30%, 2.54%, and 2.03%, respectively. The IC50 values of  ECBL, EAF, and HF were 7.51 ppm, 8.02 ppm, and 8.04 ppm, respectively. The highest flavonoid content was found in ECBL. Antioxidant activity test of Peperomia pellucida ethanolic extract, ethyl acetate fraction, and n-hexane fraction showed potent antioxidant activity.

INFLUENCE OF Momordica charantia (L.) ON THE PHARMACOKINETICS AND PHARMACODYNAMICS OF GLICLAZIDE IN ALLOXAN-INDUCED DIABETIC RATS
Authors: Akmal Tubagus , Sasongko Lucy
Published: August 2023

Diabetes mellitus is a metabolic disorder present in the top ten diseases that cause death. Diabetes treatment usually uses conventional drugs, such as gliclazide, which is the first choice in patients with type 2 diabetes mellitus who are intolerant to metformin. In addition to conventional medicine, herbal medicines are in great demand and have become a focus of research to obtain an alternative treatment for type 2 diabetes mellitus. One herb that has been widely used and studied is the bitter melon. This study aimed to determine the effects of bitter melon extract (BME) on the pharmacokinetics and pharmacodynamics of gliclazide when used simultaneously. The study was conducted on three groups of rats with alloxan-induced diabetes. Group 1 received a single dose of gliclazide (33 mg/kg BW, n = 3), group 2 received aqueous extracts of bitter melon fruit (341 mg/kg BW, n = 4), and group 3 received a combination of gliclazide and an aqueous extract of bitter melon (n = 4). The pharmacokinetic profile of gliclazide is affected by BME, where interactions occur during the absorption phase. The blood glucose levels were measured using a glucometer. Decreased blood glucose levels following administration of gliclazide, extract of bitter melon, and a combination of gliclazide and extract of bitter melon 6 hours after dosing were 74.73%, 82.977%, and 86.457%, respectively. This study demonstrated the interactions between gliclazide and BME in the absorption phase of gliclazide and its effect on blood glucose levels.
PLANOS NACIONAIS DE EDUCAÇÃO E FORMAÇÃO DOCENTE: CONTEXTO POLÍTICO E AVANÇOS DOS PNE 2001-2010 E 2014-2024
Authors: Marquez S. C. , Rezende H. P. , Silveira H. E.
Published: August 2023

Este trabalho apresenta um estudo sobre o contexto político no qual o PNE 2001-2010 e o PNE-2014-2024 foram elaborados e aprovados. Nesse âmbito, estabeleceu-se a formação de professores, bem como os paralelos do aperfeiçoamento docente e a melhoria da qualidade da educação brasileira como objeto do nosso olhar. Os textos legais destacam avanços na compreensão da formação docente, porém, não deixam evidente o modus operandi de execução das estratégias propostas nos documentos. O alcance das metas do PNE 2001-2010 sobre formação de professores foi tímido e insuficiente para resolução dos problemas relacionados à atuação profissional. Várias das metas do primeiro plano foram incorporadas ao PNE 2014-2024 que, por sua vez, ressalta o incentivo à profissionalização da docência. Este estudo demonstra alinhamento dos PNEs com diversas pesquisas educacionais sobre o trabalho docente. No entanto, o texto legal em vigência (PNE 2014-2024) foi praticamente abandonado pelo Estado brasileiro nos últimos anos, sobretudo após a inserção da educação na Emenda Constitucional 95 que institui Novo Regime Fiscal no país.

Published: August 2023

The Thulunid dynasty was the earliest manifestation of the political crystallization of the uncontrolled Turkish element at that time. the sudden emergence in the heart of the caliphate of the Abbasid dynasty was the beginning of the emergence of other minor dynasties of Turkic descent. The figure of Ahmad Ibn Thulus is a typical example of the founders of small dynasties who built their countries on the ruins of the caliphate. This dynasty was separate from the central government of Baghdad or only related to the name of the caliph in Baghdad. Much progress could be made by the Thulus dynasty even though it was short lived. The purpose of writing this scientific paper is to find out how the government of the Thuluniyyah dynasty and its contribution to the development of Islamic civilization and how the causes of the destruction of the dynasty. The analytical method used in this research is descriptive qualitative using literature study. The results of this study are that the Thulusan dynasty was a dynasty that was only 38 years old, many contributions could be made from various midwives such as territorial expansion, establishment of military grades, the field of architecture which was very luxurious and magnificent but the destruction of the Thuluniyah dynasty was due to the lack of a national base in the land they controlled so short-lived.

Occurrence and tentative population status of the Balkan Terrapin (Mauremys rivulata, Valenciennes, 1833) on Greek islands
Authors: Broggi Mario F.
Published: August 2023

The distribution of Mauremys rivulata on Aegean islands was summarized by Broggi in 2012. Here, the study area encompasses all Greek islands, including the Ionian Islands, and the two Turkish islands of Gökceada and Bozcaada. For the first time, I attempt to estimate the status and size of the populations on the islands. This is a subjective assessment based on my personal visits to most islands and not on IUCN criteria. Mauremys rivulata was found on 29 Greek islands, plus two Turkish islands in the Aegean Sea. Five previously mentioned sites are doubtful, and on the three islands of Sifnos, Syros and Ithaca the species appears to be extinct. On 12 islands I assess its status as “threatened with extinction”. On seven, mostly larger, islands its populations are probably less vulnerable. Efforts must be made for the long-term protection of M. rivulata on the Greek islands.
Influence of atmospheric circulation on the spatial distribution of precipitation in the area of Sofia city

Published: August 2023

The study aims to reveal spatial distribution of precipitation in the area of Sofia city during the decade 2013 - 2022 and the influence of atmospheric circulation. Statistical methods and cartographic approach are the main tools in this research. The spatial distribution of precipitation is characterized by low amounts (560 mm) in the northern and northeastern parts of Sofia depression and high amounts (760 mm) in the southern part. The main factor for this spatial distribution of precipitation is atmospheric circulation. The relief has a significant modifying effect and affects precipitation through several mechanisms. The most important is the location of mountain slope relative to the main direction of transport of air masses. Leeward slopes receive less precipitation and windward slopes receive more. The second mechanism of influence is anthropogenic relief (high buildings), which is a positive relief form compared to the surrounding plane having respective windward and leeward slopes. This study revealed a third mechanism of relief influence on spatial distribution of precipitation. The large difference in the height of the mountains located south of Sofia creates a significant difference in the air temperature in Sofia depression during a transport of air masses from south and southwest. This is due to the stronger foehn effect of the higher mountain (Vitosha) compared to the foehn effect of the lower mountains (Lyulin, Lozenska Planina), which creates a tongue of higher air temperature northeast of Vitosha, which reaches the southern and southwestern slopes of Stara Planina. The higher temperatures in this tongue create stronger upward air movements, which in turn increase the amount of precipitation. Secondary, but still important factors that affect the spatial distribution of precipitation in Sofia region are the urban heat island and the increased content of aerosols in the air in and over the city.
