The research has been based on surgical experience of multiple decades and on retrospect study of more that 4000 clinical cases, among them 3500 surgical invasion due to different types of traumas. Since it relies on the latter, it shows the evolution of our approaches towards severe cerebral cranial traumon includes different matters regarding diagnostics and surgical treatment with neuropathogenetic approach. We have shown the advantages of certain surgical procedures in cases of cerebral cranial trauma and also the way approaches were changing after introduction of high medical technology and taking into consideration bio mechanisms and pathological data. Computer diagnostics changed several surgical procedures and opportunities. In cases of traumas impacted in immobilized condition method of choice used to be plastic craniotomy, when in cases of cerebral congestion would cause decompression, placing bone fragment under the skin. 902 surgeries were performed among 1990. In 894 cases surgeries were performed using plastic trepanation, 217 among them was performed with improved modified method. In cases of negligible brain congestion, bone fragment was left in its place without suture fixation and after the congestion resolution fragment would return to its anatomical location. In several times it would be ligated in 2-3 points. This method was the most efficient in bi-frontal low craniotomy. The need of removing bone fragment was observed in zero cases.
In cases of acceleration traumas, which is characterized by diffuse damage, multifocal hemorrhages and bruises, in 157 cases double decompression method was used, in some case with falcostomy, effective in 49 cases. Trafination and resection trepanation were removed from practice.
Trafination method was sometimes use in cases of chronic hematomas and acute hydromas. In Recurrent and chronic hydromas method was less effective, in such conditions plastic trepanation method was used in order to create extra space for fluid. In singular cases of collapsed brain and for resolving tunica arachnoidea broken surface, we used to infuse 25-35 cubic oxygen or 20-25 distillate in spinal cord. This method was proved effective in 70 cases. Therefore, taking into consideration patho-mechanisms and pathology data, using differential pathogenetic methods of surgical invasion and computer monitoring of post-operative period we managed to decrease mortality in severecerebro-cranial traumas to 29-30% comparing to pre computer periods 36-38 % and comparing to data of other clinics 35-45%.

Authors: Черниш Наталія 
Published: November 2023

У статті розкрито образ матері у п’єсах Бертольда Брехта «Матінка Кураж та її діти» і Карела Чапека «Мати». На прикладі головних героїнь – матерів та їх дітей, показано, що війна не сумісна із життям. Проаналізовано два образи матері: Анни Фірлінг, на прізвисько Кураж (п’єса Бертольда Брехта «Матінка Кураж та її діти») та Матері (п’єса Карела Чапека «Мати»), які по-різному сприймають війну, воєнні події та втрату дітей. Обґрунтовано, що письменники у своїх п’єсах виступають проти війни та кровопролить,пророчо застерігають людство від захоплення облудними ідеями, показують страшні сторони війни. Адже ціна війни – це людські життя, це коли матері втрачають своїх дітей. Проведено паралель із сучасністю. Доведено, що ці п’єси є актуальними, мають велику силу і сьогодні, коли у нашій державі відбуваються воєнні події, коли щодня проливається людська кров, а матері втрачають своїх дітей.
Зазначено, що образ матері – це вічний образ, до якого зверталося багато письменників. Серед них і Бертольд Брехт та Карел Чапек, які у своїх п’єсах «Матінка Кураж та її діти» та «Мати» розкрили цей образ під новим кутом зору. Аналізуючи ці п’єси, першої половини ХХ століття, починаєш проводити паралелі із сьогоденням, першою половиною ХХІ століття, починаєш задумуватися над жахливими наслідками воєнних подій, над тим, кому вигідна ця війна і хто від неї зазнає страждань.
Бертольд Брехт та Карел Чапек, змальовуючи історію матерів, висловлюють думки про несумісність війни і людських чеснот, війни і самого життя. Письменники зазначають, що кожна війна має початок і кінець. Навіть Тридцятилітні війни колись закінчуються. Але поки настане мир на землі, тисячі сімей втратять своїх годувальників, матері вічно оплакуватимуть своїх загиблих синів.

Introduction. Protection of radio electronic equipment (REA) against various electromagnetic interferences is an important aspect of electromagnetic capability. Among interferences for REA, ultra-short pulses of picosecond and nanosecond ranges represent the highest danger due to their high voltage, short duration, and wide spectrum. One effective protection measure consists in the use of bandpass devices based on modal decomposition, such as modal filters (MF). This requires an analysis of distortion of the temporal response of bandpass devices, which is usually carried out numerically. However, even for simple configurations, this approach is associated with high computational costs. Yet simple analytical time-response models are acceptable in some cases. In the initial design stages, such models are extremely useful in providing a preliminary solution and a rapid assessment of response distortions. Therefore, comparison of time responses obtained by numerical methods and analytical models appears an important research task. Aim. To compare the time responses obtained by quasi-static analysis and analytical models. Materials and methods. Analytical models for computing time responses based on a modal analysis technique were considered. A quasi-static modeling of a microstrip line (MSL) with two additional symmetrical conductors on top in the TALGAT system was carried out. Results. Analytical models are proposed for an MSL with two additional symmetrical conductors on top taking different boundary conditions at their ends into account. The accuracy and reliability of the proposed models are verified by comparing the time responses obtained by quasi-static analysis and the proposed models. The results obtained showed good agreement. Conclusion. It is shown that an MSL with two additional symmetrical conductors on top can be used as an MF under different boundary conditions at the ends of these conductors. The proposed models allow the shape and amplitude of the response to be estimated with acceptable accuracy, reducing time and computational costs.

Published: November 2023

Introduction. Patch antennas have found wide application in UAVs due to their numerous useful properties. However, since such an antenna system is essentially a resonator, the problem of its matching remains unresolved. The existing publications mostly deal with specific cases and report the typical values of the matching band of 5–7 %, which cannot be considered sufficient when there is a need to use the signal spectrum of up to hundreds of MHz. Therefore, research aimed at using more efficient methods of broadband matching could be of interest for engineers. Aim. To develop a broadband matching technique based on the generalized Darlington synthesis method using flexible approximating functions (AF) for load models with resonant properties. Materials and methods. The capabilities of the generalized Darlington synthesis method are extended AFs with increased variation properties. Flexible control of AF weight coefficients makes it possible to realize both smooth and wave frequency characteristics. The method is analytical and does not use iterative procedures. The mathematical apparatus of the method is based on an analysis of deductions in the zeros of the load resistance transfer function. Results. Flexible approximating functions were established to be effective for synthesis of matching circuits with resonant properties. Solutions for matching the loads with multiple transfer zeros both at the origin and in infinity were obtained. The opportunity of creating patch antennas with a matching layer up to 40 % and more was demonstrated. Conclusion. The results obtained for the SWR of patch antennas show that the potential estimates of matching limits are available only for analytical methods.

<img src=” https://s3.amazonaws.com/production.scholastica/article/90699/large/prnano_1072023gaf.jpg?1701882189”> Tuberculosis is the second most fatal infectious disease; each year, it causes millions of deaths worldwide. Although several anti-TB drugs are currently available, the problem with these drugs is that they require a prolonged duration of treatment, with high drug doses. In addition, patient non-adherence to therapy subsequently leads to the development of multidrug-resistant and ex-tensively drug-resistant tuberculosis. Therefore, we need to develop an effective and robust nano-carrier-based drug delivery system to overcome these issues and improve the therapeutic potential of drug dose/duration and patient compliance. This review article focuses on the cur-rently available various nanotechnology-based therapeutic approaches, including lipid nanopar-ticles, polymeric particles, carbon nanotubes, glucan, and alginate-based nano-carrier systems for effective anti-TB drug delivery to host macrophage for mycobacterium killing. Finally, we also present some promising recent nanotechnology-based mycobacterial detection systems us-ing silver nanoparticles, silica nanoparticles, magnetic nanoparticles, quantum dots, and magnet-ic barcode assay that have recently emerged as the latest diagnostic tool. Functionalized nano-materials for emerging Aggregation-induced photodynamic therapy as next-generation theranostics have also been discussed as a novel option for TB diagnosis and therapy.
