Abstract

Context:
To determine the relationship between the Pederson difficulty index and the modified Parant scale and to assess the effectiveness of the Pederson difficulty index in predicting the difficulty of mandibular third molar extractions.

Settings and Design:
This cross-sectional study recruited participants with indications for third molar extractions. Pederson’s difficulty index was used to evaluate the anticipated difficulty of preoperative mandibular third molar extraction. Surgical extraction of impacted third molars was done under local anesthesia and patients were then assessed postoperatively with the Modified Parant Scale.

Methods:
In this study, 85 participants indicated for surgical extraction of mandibular third molars under local anesthesia were enrolled between February 2018 and July 2018. The relationship between Pederson’s difficulty index modified Parant scale and duration of extraction was evaluated.

Statistical Analysis Used:
Sociodemographic variables of study participants were summarized with descriptive statistics. Student’s T-test was utilized for mean differences between groups and correlations were computed between Pederson and modified Parant scale.

Results:
This study comprised 85 participants with a mean age of 25.8 years ± 4.6, showing no significant difference across genders (P = 0.87). Pederson difficulty index demonstrated a sensitivity of 46.4% and a specificity of 89.5% and a moderate correlation (0.35, P < 0.001) was observed between Pederson difficulty index and surgery duration, ditto, between Pederson and modified Parant scores (0.36, P < 0.001).

Conclusion:
In conclusion, our study underscores the importance of pre-operative assessment for mandibular third molar extraction, highlighting the Pederson Difficulty Index’s moderate predictive value but emphasizing concerns about its sensitivity.

Могильник Кызылжартас находится в Шетском районе Карагандинской области РК. В результате раскопок кургана № 2 выявлены фрагменты изделий, в том числе железного сосуда, керамики, а также 57 золотых украшений. В статье впервые публикуются результаты анализа материалов из кургана № 2, проведённых в 2023—2024 гг. В лаборатории 14С Хронологии «Vilnius Radiocarbon» (Вильнюс, Литва) по образцам из человеческих костей получены две радиоуглеродные даты. Изделия из золота были подвергнуты РФА анализу. Кости животных, найденные в могиле, были определены до вида. На основании археологических данных и результатов 14С курган № 2 могильника Кызылжартас датируется в рамках периода 2-й пол. IV—II вв. до н.э. В настоящее время в археологии раннего железного века Центрального Казахстана изучение памятников этого периода является одной из особо актуальных проблем. Рассматриваемый курган относится к группе памятников, не связанных с коргантасским и карамолинским типами. На фоне немногочисленных захоронений, сплошь ограбленных и трудно поддающихся датировке, этот объект открывает определённую перспективу в изучении культуры позднесакского времени региона.
The Kyzylzhartas burial ground is located in the Shet district of the Karaganda region of the Republic of Kazakhstan. As a result of the excavations of kurgan no. 2, fragments of products were revealed, including an iron vessel, ceramics, as well as 57 gold jewelry pieces. The article for the first time publishes the results of the analysis of materials from kurgan no. 2, conducted in 2023—2024. Two radiocarbon dates were obtained from human bone samples in the 14C Chronology laboratory of Vilnius Radiocarbon (Vilnius, Lithuania). The gold products were subjected to an RFA analysis. The animal bones found in the grave have been identified to the species. Based on archaeological data and the results of 14C, kurgan No. 2 of the Kyzylzhartas burial ground is dated within the period of the 2nd half of the 4th — 2nd centuries BCE. Currently, in the archaeology of the Early Iron Age of Central Kazakhstan, the study of monuments of this period is one of the most urgent problems. The mound in question belongs to a group of monuments unrelated to the Korgantas and Karamola types. Against the background of a few graves, completely robbed and difficult to date, this object opens up a certain perspective in the study of the culture of the Late Saka period of the region.

В статье представлены результаты исследования мужского черепа со следами трепанации. Погребение, где обнаружен краниум, относится к Ходжалы-Кедабекской археологической культуре эпохи поздней бронзы-раннего железа и было выявлено в ходе археологических раскопок Я.И. Гуммеля в Гёйгёльском районе. Трепанационное отверстие, общими размерами 2,4 × 2 см, округлой формы, расположено на венечном шве, на соединении лобной и левой теменной кости. Краниотомия была совершена методом скобления и прорезывания. На черепе присутствуют следы воспалительной реакции и заживления кости. Пациент прожил определённое время после операции. Манипуляция была осуществлена, вероятно, в медицинских целях. На черепе отмечены также дискретные признаки и маркеры физиологического стресса. В настоящее время известно 8 случаев трепанации, датируемых концом II — началом I тыс. до н.э. с территории Азербайджана: из них два (мужчины) совершены прижизненно в медицинских целях методом скобления и прорезывания (один успешно, второй — окончился смертью пациента); шесть в ритуально-символических целях, из них четыре — прижизненно выполнены методом прижигания (мужчина, женщина, два взрослых индивидуума) и два — посмертно (женщина и мужчина), методом прорезывания.
The article examines a male skull (dolichocephalic, narrow-faced, Europoid) with traces of trepanation. The burial where the cranium was found belongs to the Khojaly-Kedabek archaeological culture of the late Bronze Age to early Iron Age and was discovered during archaeological excavations by Ya.I. Gummel in the Goygol district. The trepanation hole, measuring 2.4 × 2 cm, round in shape, is located on the sagittal suture, at the junction of the frontal and left temporal bones. Craniotomy was performed by scraping and cutting. The skull shows signs of inflammatory reaction and bone healing. The patient survived for a certain period after the operation. The manipulation was likely carried out for medical purposes. The skull also exhibits discrete non-metric traits and stress markers. Currently, there are 8 cases of trepanation known, dating from the late 2nd to early 1st millennium BCE from the territory of Azerbaijan: among them, 2 (males) were performed during life for medical purposes by scraping and cutting (one successfully, the other resulting in the patient’s death); six for ritual-symbolic purposes, among them, 4 were performed during life by cauterization (male, female, 2 adult individuals) and two posthumously (female and male) by cutting.

В статье подробно рассматриваются ремесленные гончарные поселения, функционировавшие на территории Южного Приаралья в раннем железном веке и эпоху античности. Эти памятники, напрямую связанные с массовым производством глиняной посуды, различны по своему месторасположению в пределах оазисов. В связи с этим определяется их место в экономической системе области. Продукция многопрофильного ремесленного Нурумского поселения, которая явно превышала потребности его жителей, была рассчитана на скотоводческое население западных окраин Хорезма. Ремесленные поселения Хумбуз-тепе и Бабиш мола 7 снабжали своей продукцией земледельческие поселения, расположенные в пределах ирригационного района. Есть определённые основания считать, что эти крупные ремесленные центры возникали не без участия центральных властей.
The article examines in detail the artisan pottery settlements that functioned on the territory of the Southern Aral Sea region during the Early Iron Age and Antiquity. These monuments, which are directly related to the mass production of pottery, differ in their location within the oases. In this regard, their place in the economic system of the region is determined. The products of the multidisciplinary artisan Nurum settlement, which clearly exceeded the needs of its inhabitants, were designed for the pastoral population of the western outskirts of Khorezm. The artisan settlements of Khumbuz-tepe and Babishmola 7 supplied agricultural settlements located within the irrigation district with their products. There are certain reasons to believe that these large craft centers did not arise without the participation of the central authorities.

Published: November 2024

The aim of the research is to determine the relationship between learning motivation and the mathematical problem-solving ability of seventh-grade students at SMPN 1 Susua. The research approach is quantitative with a correlational research type. The population of this study consists of seventh-grade students at SMP Negeri 1 Susua, totaling 20 students, and the sampling technique used is total sampling. The instruments used are a mathematical problem-solving ability test and a questionnaire. Based on the research results, the value of tcount = 2.485813, was obtained, and to determine the ttable value with a 5% significance level, the value of rtable= 2.100922, was obtained. Therefore, since tcount = 2.485813 > ttable = 2.100922, it can be concluded that there is a relationship between motivation and mathematical problem-solving ability of seventh-grade students at SMP Negeri 1 Susua, with the level of correlation falling into the moderate category. Therefore, the researcher suggests that (1) students should have good learning motivation to achieve good mathematical problem-solving ability, (2) teachers should further develop good learning motivation to improve students' mathematical problem-solving ability, and (3) this study should be used as a comparison for future researchers and as a reference.

Published: November 2024

Background:COVID-19 pandemic had caused a global medical, economic and social problems. High infection rate, heterogenous presentation, lack of previous data and no standardized treatment had led to a need for further analysis, in order to be prepared for any potential new pandemics. We analyzed any possible correlation between gender, laboratory findings and severity of disease with need for oxygen or mechanical ventilation support.
Methods: 100 patients with confirmed SARS-CoV-2 virus infection enrolled. Baseline characteristics that included age, sex, smoking history, BMI, oxygen therapy or mechanical ventilation support need were recorded. Type and severity of radiological finding determined by chest CT scan.
Results: Majority of our patients were over 61 years old (58.6%), male (57.6%), and had severe radiological finding (bilateral pneumonia 29.3%, ARDS 35.4%), with only 20.2% had not required any oxygen supplementation. Regarding gender and laboratory findings, men have shown statistically significant higher values of CRP, lymphocytes, LDH and ferritin (96.4 vs 87.1, p=0.014; 1.17 vs 0.84, p=0.048; 674.8 vs 609.1, p=0.031; 1263 vs 578.4, p=0.001, respectfully). Severe radiological finding had shown positive correlation with the need for HFNC and/or (N)IMV (p=0.021 and p=0.032. respectfully), as well as with higher values of WBC, LDH and ferritin (p=0.042, p=0.035 and p=0.017. respectfully).
Conclusions: There is a difference between presentation of the disease, as well as analyzed laboratory markers between sexes. The difference is most likely multifactorial and should require further research in order to discover other risk and prognostic factors.

Published: November 2024

Se diseñaron, elaboraron y ensayaron dos fluidos magnetoreológicos con el objetivo de ser utilizados en distintas aplicaciones de ingeniería. Los fluidos se obtuvieron a partir de partículas de óxido de hierro ferromagnético de uso comercial diluido en una emulsión oleosa. La fracción volumétrica y la calidad de la emulsión se experimentaron hasta obtener una muestra con un tiempo de sedimentación lo suficientemente grande como para trabajar con la misma. Se caracterizaron los fluidos magneto-reológicos (MR) mediante viscosímetro. Las muestras fueron inmersas en un campo magnético generado por imanes de uso comercial y por bobinados. Se determinó la densidad de flujo magnético y se observó la viscosidad dinámica para la deformación impuesta. Los valores encontrados se compararon con otras publicaciones. Se concluye que es factible reproducir experiencias y resultados obtenidos por otros investigadores. Los fluidos MR empleados y los campos magnéticos generados son asequibles con bajos recursos. La viscosidad de los fluidos MR estudiados se incrementó, en presencia del campo magnético, tal lo pronosticado. El valor de viscosidad resultante se ajusta cualitativamente a las curvas presentadas por otros autores. A partir de estos resultados, se planea el diseño de dispositivos mecánicos que empleen fluidos MR con las características estudiadas, para distintas aplicaciones.

In this study the possibility for the improvement of accuracy of single wavelength measurements organized by multiple angle of incidence (MAI) null ellipsometry technique is shown. The “transparent film on transparent substrate” system in a range of 1.0–20.0 nm film thickness in the low-contrast region on the film-substrate surface was studied. The developed method allows an independent determination of the thickness and refractive index of an ultrathin transparent film under conditions of a strong correlation effect between these parameters.
Electrochemical lability of glycine in acid media
Authors: Survila Arvydas , Kanapeckaitė Stasė 
Published: November 2024

Electrochemical lability of different glycine species is considered on the basis of voltammetric data obtained for hydrogen evolution on the copper electrode in weakly acidic glycine solutions at different potential sweep rates (v). Voltammograms contain well-defined current peaks the height of which depends on both solution pH and glycine concentration. Current peaks and their potentials vary linearly with √−v and log v, respectively, this being typical of the electrochemical processes controlled by diffusion and charge transfer.To characterise system lability, peak coordinates and convolutive transforms of voltammograms are analysed. The results show that protons attached to different groups in a glycine molecule exhibit different mobility. In contrast to the protonated amino group, the release of a proton from the carboxylic group proceeds significantly faster. Consequently, protonated species +H3N–CH2–COOH can be treated as labile proton donors, whereas zwitterions +H3N–CH2–COO– do not fall into this category.
Modification of polyamide films by semiconductive and conductive copper selenide–copper sulfide layers
Authors: Janickis Vitalijus , Petrašauskienė Neringa 
Published: November 2024

Modification of the surface of polyamide 6 (PA) films by semiconductive and electrically conductive layers of mixed copper selenide–copper sulfide, CuxSe–CuyS, was performed using the sorption–diffusion method and the water solutions of potassium selenopentathionate, K2SeS4O6, as the precursor of polymer chalcogeniumization. Selenopentathionate anions containing divalent selenium and sulfur atoms of low oxidation state,–O3S-S-Se-S-SO3–, are sorbed-diffused into PA films if they are treated with selenopentathionate solutions. CuxSe–CuyS layers form on the surface of a PA (polyamide 6) film when a chalcogeniumized polymer is treated with a water solution of copper(II/I) salt: the anions of selenopentathionate react with copper ions. The concentration of sulfur, selenium and copper increases with an increase of the concentration and temperature of a precursor solution and the duration of PA initial chalcogeniumization. The formed layers were characterized for chemical composition, electrical and physical properties. The percentage amounts of selenium, sulfur and copper in CuxSe–CuyS layers on PA films increase with polymer chalcogeniumization time. The X–ray diffraction (XRD) pattern study of CuxSe–CuyS layers showed that they are polycrystalline in nature. The six phases of copper selenides – Cu2Se, CuSe2, CuSe2, Cu3Se2, berzellianite Cu2-xSe and bellidoite Cu2Se, also the four phases of copper sulfides – monoclinic djurleite, Cu1.9375Se, cubic digenite, Cu1.8S, orthorhombic chalcocite, Cu2S, and orthohrombic anilite, Cu1.75S, have been identified. With an increase of the concentration and temperature of the precursor solution and the duration of PA treatment the highest concentration of conductive copper selenides is reached and the composition of CuxSe phases changes in the direction of a decrease of x. XPS results confirmed the formation of copper selenides–copper sulfides layers on the surface of PA. The regularities established enable formation of CuxSe–CuyS layers of the desirable composition and conductivity. Studies by the method of atomic force microscopy (AFM) showed that depending on the conditions (duration of chalcogeniumization, concentration and temperature) of the PA initial treatment in the K2SeS4O6 solution (under the same “copperizing” conditions), the formation of copper chalcogenide layers proceeds irregularly in the form of islands which grow into larger agglomerates. The surface of the layer is uneven, rather rough.
