Authors: Rudnick Abraham , Nolan Dougal , Daigle Patrick 
Published: September 2024

SOMMAIRE NON SCIENTIFIQUE Il faut de l’information sur la santé mentale des vétéran(e)s militaires du Canada pour créer et améliorer des services de santé mentale. Il n’est pas évident dans quelle mesure cette information est accessible et reliée entre les sources. Un examen complet des publications scientifiques et d’autres publications autorisées a été réalisé pour trouver les sources d’information concernant la santé mentale des vétéran(e)s canadien(ne)s, la relation entre ces renseignements, et les politiques et directives qui les visent. Nous avons trouvé dix sources de données concernant la santé mentale des vétéran(e)s au Canada, mais nous n’avons trouvé aucune politique ni directive visant spécifiquement le partage de cette information pour l’ensemble de ces données. Parmi ces sources, le partage d’information sécurisée, accessible, fiable et efficace (SAFE) était sous-entendu sans être confirmé. Les auteurs recommandent d’envisager l’établissement d’un répertoire d’ensembles de données pertinentes, de politiques et de directives pour le partage d’information et l’uniformisation de tous les ensembles de données.

Colorectal cancer is the third most common cancer in the world. Despite recent therapeutic advances, it causes more than 500,000 deaths each year. The immune system plays a crucial role in protecting the body from cancer. However, cancer cells are able to evade immune detection and destruction. For example, they can downregulate antigen expression, produce immunosuppressive molecules, or recruit immune cells that perform regulatory or inhibitory functions. Understanding the complex interactions between the immune system and carcinogenesis is crucial for developing effective cancer treatments. The study aimed to determine the morphological changes in the thymus, spleen, and lymph nodes under N,N-dimethylhydrazine-induced carcinogenesis. The study was performed on 77 male outbred albino rats weighing 190-230 g, kept in standard vivarium conditions. Colon adenocarcinoma was modeled by administration of N,N-dimethylhydrazine hydrochloride for 30 weeks. To study the peculiarities of morphological and functional changes in lymphoid organs in the dynamics of colon tumor lesions, animals were withdrawn from the experiment every 30 days. Paraffin sections of the thymus, spleen, and lymph nodes 5-6 μm thick were made on a rotary microtome and stained with hematoxylin and eosin. The experimental investigation unveiled the character and extent of histological alterations within the lymphoid system organs under conditions of N,N-dimethylhydrazine-induced colon adenocarcinomatosis. As the experiment progressed, there was a noticeable escalation in the severity of detrimental and degenerative modifications observed in the thymus, spleen, and lymph nodes. These modifications were evident in the disruption of blood circulation within the examined organs, leading to vascular wall impairment and hemorrhaging, the disarray of morphofunctional elements and the development of fibrosis. Given the significant role played by the thymus, spleen, and lymph nodes in regulating carcinogenesis and maintaining immune balance, it is extremely important to delve into understanding the changes in their structure and function. Obtained results indicate that carcinogenesis is accompanied by pronounced morphological changes in the structural components of the lymphoid system organs, the degree of which increases in direct proportion to the duration of exposure to the oncogenic factor.

The optimal conditions for demetallization of the heavy fraction of coal tar from Shubarkol Komir JSC were determined by means of full factorial experiment. Optimal conditions for demetallization of the aforementioned fraction were found to be a proportion of “Coal shale” catalytic additive to the heavy fraction of coal tar with boiling point above 300 °С equal to 0.04, process temperature in the range of 420–430 °С, duration from 20 to 30 minutes and initial pressure between 3 and 5 MPa. Experiments conducted under these conditions demonstrated the demetallization rates of 87–89 %. Conversion of the heavy fraction of coal tar in hydrogen medium at pressure of 4.0 MPa and temperature of 420 °C was examined, with and without the use of the “Coal Shale” catalytic additive. The findings demonstrate that the incorporation of the “Coal Shale” catalytic additive is associated with a notable enhancement in the production of liquid hydrogenate, reaching up to 57 %. Atomic emission spectral analysis was used to investigate the content of rare and dispersed elements including Ge, Ga, Y, Yb, Zr, Nb the ash of the heavy fraction of coal tar and the “Coal shale” catalytic additive, as well as in the solid product of demetallization of the heavy fraction of coal tar using the catalytic additive. The results showed that the use of “Coal shale” as the catalytic additive leads to an increase in the content of Ga, Yb, Y elements by 3-3.8 times, and Zr — by 7.5 times compared to the initial heavy fraction of coal tar in the absence of the catalytic additive.

Production of artificial humic acid (AHA) from waste biomass will contribute to environmental protection and agricultural productivity. However, there is still a lack of a faster, more efficient and eco-friendly way for sustainable production. In this study, potassium humate was prepared from agricultural waste tobacco straw by thermal catalysis using environmentally friendly Fe2O3 as a catalyst. The yield of potassium humate was successfully increased to 68.77 %. In the present study, using characterization methods such as TG-DTG and UV, it was found that the potassium humate prepared from tobacco straw had lower aromaticity, smaller molecular weight, as well as better solubility and better quality. In addition, the effect of potassium humate fertilizer on wheat biomass was also investigated in this experiment by wheat hydroponics. The results showed that the germination rate of wheat increased by 17 % and the fresh and dry weights increased by 6.94 % and 19.31 %, respectively, with the addition of potassium humate prepared with iron catalyst. This study provides a green and simple technology for the resourceful utilization of tobacco straw to produce high value-added potassium humate, and enriches the source of raw materials for potassium humate, expanding its application in the field of crop growth.

Introducción: la siguiente investigación tiene por objeto establecer las causalidades necesarias y suficientes que repercuten sobre la obtención de resultados desfavorables en el deporte de alto rendimiento durante las competencias del ciclo olímpico comprendidas entre los años 2008 al 2017. En este sentido, se ha recurrido al análisis comparativo de los siguientes países de América Latina; Ecuador, Colombia, México, Argentina, Cuba, Jamaica y Venezuela. Metodología: Se utilizó como marco metodológico referencial un QCA[1] para determinar los factores de mayor incidencia sobre la obtención de resultados desfavorables. Resultados: De este modo, se categorizó la variación de resultados favorables como un fenómeno multicausal y coyuntural. Discusión: por consiguiente, se determinó que las causas de mayor influencia fueron aquellas relacionadas con la presencia de un aparato burocrático grande, un tipo de financiamiento deportivo mayoritariamente público y la presencia de mecanismos de injerencia estatal. Conclusiones: se observó que la burocratización del deporte de alto rendimiento es un fenómeno desprendido de un proceso previo de politización. Por tanto, en aquellos países donde el espectro de politización es más alto existe un deterioro de resultados más pronunciado, mientras que aquellos que no manifiestan síntomas de politización muestran un crecimiento sostenido de sus resultados.

OBJECTIVE
Guidelines for the management of pediatric severe traumatic brain injury (TBI) recommend external ventricular drainage for CSF drainage as a first-tier treatment in the intracranial pressure (ICP) pathway. However, ventriculostomy in children can sometimes be challenging because of the small size of the lateral ventricles. External lumbar drainage (ELD) may be a useful alternative; therefore, the authors analyzed the outcome of a cohort of pediatric patients who underwent ELD to manage intracranial hypertension (ICH).

METHODS
This study retrospectively enrolled pediatric patients with ICH following severe TBI who underwent ELD. Radiological and clinical severity scores (Marshall classification, Rotterdam score, Injury Severity Score, and Pediatric Trauma Score) were noted. ICP and cerebral perfusion pressure (CPP) curves were analyzed 12 hours before and after the procedure. Any change in medical therapy was recorded, as well as the total volume and duration of drainage. Cerebellar tonsillar position according to the McRae line was noted before and after ELD. Glasgow Outcome Scale-Extended score at follow-up was also noted.

RESULTS
Thirty patients were included, with a mean age of 8 ± 4.4 years, and a median admission Glasgow Coma Scale score of 7 ± 4 (range 3–13). ELD was performed after a median delay of 1 day (range 0–7 days), mean drainage volume/day was 296 ± 129 ml, and median duration of drainage was 7 ± 5 (range 2–12) days. Forty-three percent of the patients underwent ELD as a part of the first-tier therapy. ICP decreased after ELD (mean difference 13.4 ± 6.2 mm Hg, p < 0.001), whereas CPP increased (mean difference 10.6 ± 6.4 mm Hg, p < 0.001). Fifty-three percent of the cohort did not need any further second-tier therapy after ELD. The study found 1 case of drain revision and 3 cases of cerebellar tonsil herniation.

CONCLUSIONS
These preliminary data suggest ELD is a valuable option to treat ICH in severely head-injured children, limiting the use of second-tier treatments. This pilot study should lay the foundation for a multicenter prospective trial.
Age as a predictor of reoperations and complications in surgically managed pediatric Chiari malformation type I
Authors: Johnstone Thomas , Barros Guinle Maria Isabel , Prolo Laura M. , Grant Gerald A. 
Published: September 2024

OBJECTIVE
Chiari malformation type I (CM-I) is defined by the herniation of the cerebellar tonsils into the spinal canal. When symptomatic, surgical decompression is recommended. Reported CM-I reoperation rates have ranged from 3% to 30%. However, the relationship between patient age at first surgical intervention and the likelihood of reoperation and postoperative complications remains poorly characterized. Therefore, this study aimed to determine whether patient age was associated with reoperation and complication rates.

METHODS
Patients 0–21 years old with a diagnosis of CM-I and surgical decompression were queried from the 2007–2021 MarketScan databases. Patient sex, age at time of first procedure, comorbidities, 90-day postoperative complications, and reoperations were identified. Bootstrap-augmented binary classifiers were constructed to determine the optimal timing of first surgical decompression with respect to all-cause 90-day postoperative complications and reoperation. Multivariate logistic regression models were built to assess the relationship between age, sex, and comorbidities and the likelihood of reoperation and complications following surgical decompression.

RESULTS
A total of 2675 patients were included for analysis of 90-day postoperative complications, and 1157 were included in the reoperation analysis cohort. A total of 524 patients (19.6%) experienced a complication within 90 days of surgical decompression, and 84 patients (7.3%) had reoperations. On multivariate regression, increased age was an independent predictor of a reduced likelihood of both reoperations (OR 0.94, 95% CI 0.90–0.98; p < 0.01) and 90-day postoperative complications (OR 0.96, 95% CI 0.94–0.98; p < 0.01). The optimal age cutoff to predict both complications and reoperations was 4 years. For patients ages 4 years and older, both the reoperation rate (5.5% vs 13.2%, p < 0.01) and 90-day postoperative complication rates (18.4% vs 27.7%; p < 0.01) were significantly less than those for children 3 years and younger.

CONCLUSIONS
In a national cohort of pediatric patients undergoing surgically managed CM-I, there was a significantly increased likelihood of reoperation and complications in patients ages 3 years and younger. Although CM-I decompression should not be postponed in the face of progressive neurological deficits, the authors’ findings suggest that delaying surgery until after the age of 3 years, when medically feasible, may help mitigate adverse events.
ПОДАТКОВА РЕФОРМА ЯК ВИМОГА ЧАСУ

Published: September 2024

Досліджено стан реформування податкової системи України. Зазначено, що проблеми податкової системи досі залишаються найбільшими перешкодами не лише для ведення бізнесу, а й для наповнення казни. Реформа податкової та митної служби триває, але спрогнозувати її результативність досі вкрай важко. Наголошено, що найважливішим методом акумуляції державою фінансових ресурсів стали податки, які забезпечують левову частку бюджетних надходжень. Зауважено, що зниження їхньої частки впродовж 2022–2023 рр. є результатом встановлених податкових пільг і послаблень для підтримки бізнесу та громадян під час воєнного стану. Серед низки реформ Державної податкової служби основну увагу сконцентровано на пакеті змін до податкової системи України, який отримав назву «Податкова реформа 10-10-10», та ухваленій Національній стратегії доходів на 2024–2030 роки. Наголошено на меті цієї реформи, яка полягає у зменшенні податкового тягаря для бізнесу та громадян, що, у свою чергу, має позитивно позначитись на економічному зростанні. Зазначено, що стратегія є однією з умов Міжнародного валютного фонду в рамках співпраці з Україною впродовж чотирирічної програми, діятиме до кінця березня 2027 року, передбачає виділення Україні 15,6 мільярдів доларів та містить як корисні, так і спірні для економіки пропозиції. Особливу увагу приділено запропонованій реформі спрощеної системи оподаткування (ССО), яка передбачає перегляд переліку галузей діяльності, що допускаються до першої групи, щоб виключити з неї високооборотні бізнеси зі встановленою ставкою з фактично отриманого доходу; об’єднанням другої та третьої групи спрощеної системи оподаткування в одну групу з диференційованою шкалою; запровадження ставки єдиного податку для юридичних осіб третьої групи з поступовим збільшенням до рівня звичайної ставки податку на прибуток (18 %). Дійдено висновку, що збільшення податкового навантаження і введення додаткових обов’язків для платників спрощеної системи можуть призвести до припинення або ліквідації частини бізнесу, оскільки для них працювати за новими правилами стане неоптимальним, що матиме негативні наслідки для бюджету, зайнятості, трудової міграції та інших аспектів економіки.

Published: September 2024

UAVs are commonly used in transportation, especially in the express delivery of light cargo parcels. However, controlling UAVs is difficult because of their complex structure and wide range of operations in space. The research contribution is proposed a cascade control structure using six PID controllers for the 6-DOF UAV quadcopter, that ensures the altitude angulars positions control at the desired values and maintains flight balance stability for the 6-DOF UAV quadcopter. First, the mathematical dynamic models for the 6-DOF UAV quadcopter have been researched and developed, including the translational dynamic mathematical model and the rotational dynamic mathematical model of the 6-DOF UAV quadcopter. This is a complex object with strong nonlinearity and difficult control. And then, the article introduces the method of designing six PID controllers for 6-DOF UAV quadcopter to meet the requirements, based on applying the Ziegler-Nichols experimental method. Applying the Ziegler-Nichols experimental method makes the process of designing a UAV quadcopter control system simple, straightforward and heuristics with fast controller parameters tuning. Next, the article presents the results of modeling and simulation of the 6-DOF UAV quadcopter control system on Matlab/Simulink. The simulation results show that the six proposed PID controllers have ensured the flight balance stability at the desired altitude and angular positions with overshoot less than 20%, steady-state error less than 1%. This shows the prospect of applying the proposed PID control method to physical UAVs, easily adjusting PID parameters to suit the flight environment.
Honey Badger Algorithm Based DVR Controllers for Improved Power Quality‏ in a Microgrid Combined of (Wind System\ Grid\Nonlinear Load)
Authors: Zidan Ahmed Atef , Ibrahim Ahmed M. , Omar Ahmed I. 
Published: September 2024

Power quality (PQ) is crucial in today's energy supply networks, where even little voltage fluctuations can have a big impact on how well household appliances and technologies operate. The suggested dynamic voltage regulator (DVR) approach helps to create a new generation power grid that is more dependable and effective. In this study, the honey badger optimizer (HBO) is used to optimize the controllers of the DVR for improving PQ via voltage control. The efficacy of the optimized DVR is further increased by its integration with a microgrid (MG) wind supply. The suggested technique makes use of a low-complexity control approach for voltage regulation to adjust for harmonic distortion, swells, and voltage dips in the addressed system. The technique accomplishes voltage improvement, bus stabilization, energy-efficient utilization, and harmonic distortion reduction by using the DVR in conjunction with an MG wind supply. Various voltage disturbances, such as balanced and unbalanced swell and sag, voltage imbalance, notching, various fault states, and power system harmonic distortion, are taken into consideration to show the approach's usefulness. The findings indicate PQ enhancement, demonstrating that the load voltage roughly matches the nominal value.
