MOVEMENT OF GRAIN BETWEEN THE CYLINDERS OF A SEMI-AUTOMATIC ROTARY DRYER DURING HEATING
Authors: Николаев В.А. 
Published: September 2024

Конструкция полуавтоматической универсальной роторной сушилки, предназначенной для сушки материалов и изделий сельскохозяйственного и подсобного производства, имеет существенные отличия от сушилок, используемых в настоящее время в хозяйствах. Для данной сушилки необходима разработка теории загрузки, выгрузки и сушки различных материалов, в том числе зерна. Эффективность сушки зависит от многих факторов, в частности, от движения зерна в пространстве между внешним цилиндром и внутренним цилиндромза период его прогрева и сушки. В эти периоды слой зерна в пространстве между внешним цилиндром и внутренним цилиндром разделяется на три подслоя: А, Б,В. В подслое А и подслое В будет осуществляться не только конвективный нагрев зерна, но и перенос тепла зерном при его прогреве. В подслое Б осуществляется только конвективный нагрев зерна, почти не осуществляется перенос тепла зерном. Поэтому наличие подслоя Бнежелательно, либо толщина его должна быть минимальной. Единственно возможным путём уменьшения толщины подслоя Бявляется увеличение ширины лопастей на внутреннем цилиндре. С другой стороны, увеличение ширины лопастей на внутреннем цилиндре приведёт к увеличению соотношения скоростей потока воздуха по периметру внутреннего цилиндра. Окончательно оптимальную ширину лопастей на внутреннем цилиндре можно выявить только после расчёта всего процесса сушки зерна.
The design of a semi-automatic universal rotary dryer designed for drying materials and products of agricultural and auxiliary production has significant differences from the dryers currently used on farms. For this dryer, it is necessary to develop the theory of loading, unloading and drying of various materials, including grain. The efficiency of drying depends on many factors, in particular, on the movement of grain in the space between the outer cylinder and the inner cylinder during the period of its heating and drying. During these periods, the grain layer in the space between the outer cylinder and the inner cylinder is divided into three sublayers: A, B, V. In sublayer A and sublayer V, not only convective heating of the grain will be carried out, but also heat transfer by the grain during its heating. In sublayer B, only convective heating of grain is carried out, almost no heat transfer by grain is carried out. Therefore, the presence of sublayer B is undesirable, or its thickness should be minimal. The only possible way to reduce the thickness of sublayer B is to increase the width of the blades on the inner cylinder. On the other hand, an increase in the width of the blades on the inner cylinder will lead to an increase in the ratio of air flow rates along the perimeter of the inner cylinder. The final optimal width of the blades on the inner cylinder can be revealed only after calculating the entire grain drying process.

В данном исследовании представлен инновационный подход к созданию и внедрению каскадных систем управления, включающих в себя как пропорционально-интегрально-дифференциальный (ПИД), так и пропорционально-интегральный (ПИ) регуляторы, предназначенных для синхронизированного контроля скорости вращения и токового режима якоря в двигателях постоянного тока. Для нахождения оптимальных параметров регуляторов применяется метод Циглера-Николса, обеспечивающий стабильность системы управления. Каскадная архитектура управления, основанная на разделении контуров регулирования, демонстрирует высокую эффективность благодаря устранению конфликтов между задачами управления скоростью и током. Этот подход значительно улучшает производительность и надёжность работы двигателя. Для оценки предлагаемой системы управления используется программное обеспечение, работающее в режиме реального времени и обеспечивающее связь между персональным компьютером и Arduino Mega через последовательный интерфейс. Модель двигателя постоянного тока разрабатывается в среде Simulink, а каскадный ПИД-ПИ регулятор реализуется на Arduino Mega. Интеграция модели двигателя с Arduino Mega осуществляется посредством последовательной связи, обеспечивая тем самым эффективное взаимодействие между программным и аппаратным обеспечением.
This study presents an innovative approach to the creation and implementation of cascade control systems, including both proportional-integral-differential (PID) and proportional-integral (PI) controllers, designed for synchronized control of the rotation speed and current mode of the armature in direct current motors. To find the optimal parameters of controllers, the Ziegler-Nichols method is used, which ensures the stability of the control system. The cascade control architecture based on control loop separation demonstrates high efficiency by eliminating conflicts between speed and current control tasks. This approach significantly improves engine performance and reliability. To evaluate the proposed control system, real-time software is used to provide communication between the personal computer and the Arduino Mega via a serial interface. The direct current motor model is developed in the Simulink environment, and the cascade PID-PI controller is implemented on the Arduino Mega. The integration of the motor model with the Arduino Mega is done through serial communication, thereby ensuring efficient interaction between software and hardware.

Abstract
Resistive random access memories (ReRAMs) based on an organic-metallic hybrid polymer, Poly(Fe-btpyb) Purple, were fabricated. This material was synthesized by complexation of metal ions and organic ligands. When applying forward bias, an abrupt resistance change from a low resistance state (LRS) to a high resistance state (HRS), which is known as the reset process, was observed. In contrast, a reverse bias switched the resistance from HRS to LRS (set process). The resistive switching phenomenon is probably caused by the electrochemical oxidation-reduction reaction of the metal ion (Fe(II)/Fe(III)). The nonvolatile memory characteristics were measured with data-retention tests, showing no significant degradation over 10−5 sec. The endurance characteristics exhibited sufficient long-term durability, due to no conformational change of the organic ligand. It is proposed that the difference in charge-transfer efficiency between the reduced state (Fe(II)) and oxidized state (Fe(III)) might be the physical mechanism of the resistive switching.

Revisiting the paleolithic reindeer of Moldova: an in-depth analysis
Authors: Croitor Roman 
Published: September 2024

This study examines reindeer remains from Paleolithic sites in Moldova, including re-description and reclassification of antler findings, and identifies a previously undocumented complete antler from Cosăuți. The antler from Duruitoarea Veche is determined to be from red deer (Cervus elaphus), consistent with the site’s fauna. Using a t-test on talus samples, the study investigates body size variations between an older reindeer form from Duruitoarea Veche and Brînzeni 1, and the younger R. tarandus constantini from Cosăuți. Results show no statistically significant differences in body size, but confirm the larger cheek teeth in R. tarandus constantini. Reindeer from Rașcov 7 are reclassified as R. tarandus cf. constantini, with relatively large cheek teeth.

Purpose: A comparative study of the content of lipid peroxidation (LPO) products and the activity of the main antioxidant enzymes in the blood plasma of patients with brain metastases (BM) under various radiotherapeutic treatment options.Material and methods: The study included 37 patients with BM. Three groups of patients were formed: Control group (12 patients), in which stereotactic radiotherapy with a single focal dose of 6 Gy to a total dose of 30 Gy was performed on the place of the removed metastasis; Main group No. 1 (6 patients) — after a session of preoperative radiosurgery with a dose of 10-15 Gy, the metastatic focus was removed after 24 hours; Main group No. 2 (19 patients) — staged radiosurgery (SRS) was carried out in 3 stages with a dose of 10 Gy with an interval between sessions of 14 days (total dose of 30 Gy). In the blood plasma of 37 patients, the content of malondialdehyde (MDA), diene conjugates (DC), and the activity of superoxide dismutase and catalase were determined by standard spectrophotometric methods. The comparison group included 21 people without cancer (donors). Statistical processing of the results was carried out using the Statistica 10.0 program. using Student’s t-test and nonparametric Mann–Whitney test.Results: Before treatment, the MDA content was increased in all patients, on average by 83.5 % (p = 0.00025) relative to the donor group; in the majority, DC was also increased (by 60.4 %, p = 0.0498). After removal of the metastatic lesion in patients in the Control and Main group No. 1, the level of LPO products remained elevated. And only in the Main Group No. 2, already before the 3rd session of SRS, a decrease in the level of MDA was observed in patients with a removed primary lesion, as well as normalization of DC in all patients and restoration of the coordinated work of antioxidant enzymes. An increase in MDA content with reduced catalase activity in patients with an unremoved primary lesion at the stages of SRS may reflect the mechanism of tumor cell reduction under the influence of increased production of free radicals during long-term radiation exposure.Conclusions: The use of SRS, in contrast to other radiotherapy options, helps to normalize the redox status of the blood of patients with metastatic brain lesions. Analysis of the data obtained suggests greater effectiveness of SRS in patients with a removed primary lesion.

Authors: Yang Fan , Jiang Na , Li Xiao-Yu , Qi Xing-Si , Tian Zi-Bin , Guo Ying-Jie 
Published: September 2024

BACKGROUND
Pancreatic cancer is one of the most lethal malignancies, characterized by poor prognosis and low survival rates. Traditional prognostic factors for pancreatic cancer offer inadequate predictive accuracy, often failing to capture the complexity of the disease. The hypoxic tumor microenvironment has been recognized as a significant factor influencing cancer progression and resistance to treatment. This study aims to develop a prognostic model based on key hypoxia-related molecules to enhance prediction accuracy for patient outcomes and to guide more effective treatment strategies in pancreatic cancer.
AIM
To develop and validate a prognostic model for predicting outcomes in patients with pancreatic cancer using key hypoxia-related molecules.
METHODS
This pancreatic cancer prognostic model was developed based on the expression levels of the hypoxia-associated genes CAPN2 , PLAU , and CCNA2 . The results were validated in an independent dataset. This study also examined the correlations between the model risk score and various clinical features, components of the immune microenvironment, chemotherapeutic drug sensitivity, and metabolism-related pathways. Real-time quantitative PCR verification was conducted to confirm the differential expression of the target genes in hypoxic and normal pancreatic cancer cell lines.
RESULTS
The prognostic model demonstrated significant predictive value, with the risk score showing a strong correlation with clinical features: It was significantly associated with tumor grade (G) (bP < 0.01), moderately associated with tumor stage (T) (aP < 0.05), and significantly correlated with residual tumor (R) status (bP < 0.01). There was also a significant negative correlation between the risk score and the half-maximal inhibitory concentration of some chemotherapeutic drugs. Furthermore, the risk score was linked to the enrichment of metabolism-related pathways in pancreatic cancer.
CONCLUSION
The prognostic model based on hypoxia-related genes effectively predicts pancreatic cancer outcomes with improved accuracy over traditional factors and can guide treatment selection based on risk assessment.

Authors: Arup Deka  , Ratul Mahanta  
Published: September 2024

Healthcare resources should not be misused as such resources can save people's life. Further, avoiding excessive resource employment can help minimize production costs. In this regard, measuring technical efficiency is essential as it helps identify the resource utilization level against the output level. The present study has estimated the relative technical efficiency scores of private hospitals in the Kamrup (Metro) district of Assam. The data for the study is collected from primary and secondary sources for the year 2019. Bootstrapping Data Envelopment Analysisis applied considering two outputs and six input variables. All the hospitals are technically inefficient; however, small size hospitals have shown better performance in terms of technical efficiency than big size hospitals.
The study has not distinguished the number of inpatients based on the resources consumption. In this context, there is a further scope to improve the study. However, this is the first attempt to analyse the performance of private hospitals in terms of technical efficiency in Assam. It will help the management of concerned hospitals to improve their resource utilisation strategy.

Published: September 2024

Background: Suicide has been noted as a distressing phenomenon among the society, in one way or the other. It poses a serious public health problem and requires meticulous in depth probing with all the compassion for the victims of suicide.The aim of this study is to assess the predictors of suicidal behaviour in young adults and suggest novel suicide prevention policies.

Materials and Methods:It was a hospital based descriptive cross-sectionalstudy conducted over 18 months amongst suicide attempters in the age range of 18 to 35 years who were brought to the Casualty and Psychiatry department of a tertiary care hospital of north India.100 consecutive suicide attempters,who gave voluntary written informed consent were enrolled. Socio-demographic profile, details of past psychiatric illness, family history of psychiatric illness, previous suicidal attempt and history of substance abuse were recorded. Psychiatric morbidity was assessed using Mini International Neuropsychiatric Interview (MINI) and confirmed on International Classification of Diseases 10th edition (ICD-10).Depression, Anxiety and Stress were assessed on Depression anxiety and Stress Scale-21(DASS-21). Beck Suicide Intent Scale (BSIS)was used to measure severity of suicide intent and to find out any association between presence of past psychiatric history/family history of psychiatric illness/previous suicide attempt with suicide intent

Results: Out of 100 attempted suicidal patients, male to female ratio was 1.44:1.Past psychiatric illness, family history of psychiatric illness, previous suicidal attempt and substance abuse was observed among 23% (n=23), 19%(n=19), 23% (n=23)and 34% (n=34) patients, respectively. 59%(n=59) patients were found to be having psychiatric illness currently. Overall Mean±SD score of severe depression was 25.64±12.36, severe anxiety (19.38±9.39) and moderate stress (24.18±8.61) as assessed on Depression anxiety and Stress Scale-21 items(DASS-21).67%(n=67) patients had high suicide intent on Beck Suicide Intent Scale (BSIS).There was positive association between past psychiatric illnesses and BSIS i.e.,91.3% compared to 59.7% without psychiatric illness(c2=18.589, p=0.001).
Conclusion: Multifactorial indicators and psychological aspects such as depression, anxiety, stress and substance abuse reaffirm its causality with high suicide intent and a forerunner for subsequent attempts.
