Published: December 2022

Обоснована актуальность совершенствования конструкции устройств для удаления вредных веществ в системах местной вытяжной вентиляции, которые способствуют созданию для создания нормируемых параметров воздушной среды в локальном объеме рабочей зоны производственного помещения путем удаления загрязненного воздуха непосредственно от источника (технологического оборудования) выделения вредностей. Разработана конструкция, позволяющая при малых расходах отсасываемого (удаляемого) воздуха обеспечивать концентрации загрязняющих вредных веществ на допустимом нормами уровне. При этом работа вытяжного устройства взаимосвязана с выполнением технологического процесса таким образом, чтобы минимизировать выделение вредных веществ в помещение на различных этапах его выполнения; регулирование работы местного отсоса может происходить в ручном или автоматическом режимах. Показано, что применение описываемого устройства позволит снизить капитальные (вентиляционное оборудование, изделия и материалы) и эксплуатационные (тепловая и электрическая энергия) траты при организации вентиляционных систем в гальванических и травильных цехах производственных зданий.
The relevance of improving the design of devices for removal of harmful substances in local exhaust ventilation systems is substantiated. There systems are designed to create standardized parameters of the air environment in the local volume of the working area of the production facility by removing polluted air directly from the source of harmful substances (technological equipment). The construction is designed to ensure the concentration of polluting harmful substances at low flow rates of sucked (removed) air at a level permitted by the norms. At the same time the suction unit operation is interconnected with the technological process execution in such a way as to minimize pollutant emission into the room at different stages of its performance. The regulation of the local suction unit operation can be carried out in the manual or automatic modes. It is shown that the use of the described device will reduce capital (ventilation equipment, products and materials) and operating (heat and electric power) costs when organizing ventilation systems in galvanic and pickling shops of production buildings.

В статье представлено исследование многообразия вредоносного программного обеспечения для разработки модулей автоматизированной информационной системы моделирования эпидемических процессов, порожденных саморазмножающимися и мутирующими вредоносами. Приведена классификация саморазмножающихся и мутирующих вредоносов, приводится информационное обеспечение, определяющее параметры саморазмножения и мутации вредоносов, а также антивирусных средств защиты информации. Предложено методическое и алгоритмическое обеспечения, на базе которых были разработаны модули автоматизированной информационной системы моделирования эпидемического процесса в сети с произвольной топологией, порожденного саморазмножающимися и мутирующими вредоносами. В отличие от аналогов разработанные модули автоматизированной информационной системы способствуют моделированию процесса развития эпидемии, а также учитывают снижение способности обнаружения вредоноса в компьютерной сети антивирусным средством защиты информации из-за модификаций, вызванных механизмом мутации вредоноса. Анализируемые методические процедуры и полученные результаты моделирования могут быть востребованы для реализации риск-анализа эпидемических процессов, порожденных мутирующими вредоносами, для последующего обеспечения безопасности компьютерных сетей различного назначения.
This article is aimed at investigating the variety of malicious software for the development of modules of an automated information system for modeling epidemic processes generated by self-propagating and mutating malware. The paper describes the classification of self-propagating and mutating malware, provides information support that determines the parameters of self-propagatingand mutation of malware, as well as anti-virus information protection tools. The article proposes methodological and algorithmic support, on the basis of which modules of an automated information system for modeling the epidemic process in a network with an any topology generated by self-propagating and mutating malware were developed. Unlike analogues, the developed modules of the automated information system contribute to modeling the epidemic development process, and also take into account the decrease in the ability to detect a malware in a computer network by an antivirus information protection tool, due to modifications caused by the mutation mechanism of this very malware. The analyzed methodological procedures and the obtained modeling results can be used to implement risk analysis of epidemic processes generated by mutating malware, for subsequent security of computer networks for various purposes.

Predictability reduces event file retrieval

Published: December 2022

AbstractThere is growing consensus that stimulus–response bindings (event files) play a central role in human action control. Here, we investigated how the integration and the retrieval of event files are affected by the predictability of stimulus components of event files. We used the distractor–response binding paradigm, in which nominally task-irrelevant distractors are repeated or alternated from a prime to a probe display. The typical outcome of these kinds of tasks is that the effects of distractor repetition and response repetition interact: Performance is worse if the distractor repeats but the response does not, or vice versa. This partial-repetition effect was reduced when the distractor was highly predictable (Experiment 1). Separate manipulations of distractor predictability in the prime and probe trial revealed that this pattern was only replicated if the probe distractors were predictable (Experiment 2b, 3), but not if prime distractors were predictable (Experiment 2a). This suggests that stimulus predictability does not affect the integration of distractor information into event files, but the retrieval of these files when one or more of the integrated features are repeated. We take our findings to support theoretical claims that integration and retrieval of event files might differ concerning their sensitivity to top-down factors.

Gamma Cas Stars as Be+White Dwarf Binary Systems
Authors: Gies Douglas R. , Wang 王 Luqian 璐茜 , Klement Robert 
Published: December 2022

Abstract
The origin of the bright and hard X-ray emission flux among the γ Cas subgroup of B-emission line (Be) stars may be caused by gas accretion onto an orbiting white dwarf (WD) companion. Such Be+WD binaries are the predicted outcome of a second stage of mass transfer from a helium star mass donor to a rapidly rotating mass gainer star. The stripped donor stars become small and hot white dwarfs that are extremely faint compared to their Be star companions. Here we discuss model predictions about the physical and orbital properties of Be+WD binaries, and we show that current observational results on γ Cas systems are consistent with the expected large binary frequency, companion faintness and small mass, and relatively high mass range of the Be star hosts. We determine that the companions are probably not stripped helium stars (hot subdwarf sdO stars), because these are bright enough to detect in ultraviolet spectroscopy, yet their spectroscopic signatures are not observed in studies of γ Cas binaries. Interferometry of relatively nearby systems provides the means to detect very faint companions including hot subdwarf and cooler main-sequence stars. Preliminary observations of five γ Cas binaries with the CHARA Array interferometer show no evidence of the companion flux, leaving white dwarfs as the only viable candidates for the companions.

Геријатриската популација во Македонија претставува специфична група која има потреба од континуирана евалуација на нивното орално здравје. Според податоците на СЗО во 2010 година, 12 % од населението во Македонија било на возраст 65+ години. Стареењето е процес со различни специфични промени во сите системи и органи, вклучувајќи го и орофацијалниот систем. Најчестите состојби поврзани со возраста кај геријатриската популација се губење на забите, пародонтопатија, преканцерозни лезии и орални карциноми, ксеростомија, ресорпција на резидуалниот алвеоларен гребен и целокупна дисфункција на орофацијалниот систем. Големо е влијанието на извршената протетичка терапија кај геријатриските пациенти врз нивното целокупно и општо здравје. Целта на оваа студија беше да се процени состојбата на меките ткива кај геријатриските пациенти, особено кај пациентите со протетички третмани, нивното орално здравје и влијанието на оралното здравје врз квалитетот на животот. Материјал и методи: Спроведовме опсервациона студија на пресек кај геријатриските пациенти, а геријатрискиот индекс за проценка на оралното здравје (GOHAI) беше употребен за да се изврши евалуација на нивното орално здравје и влијанието на оралните состојби и извршениот дентален третман врз квалитетот на животот. Резултати: Испитаниците со просечна возраст од 72,88 години пријавиле повеќе општи и системски заболувања, а главните фактори на ризик за промените на оралната мукоза биле пушењето и пиењето алкохол. Вкупна анодонција е забележана кај 37,5% од испитаниците и делумна анодонција кај 62,5%. Просечниот период на носење протези изнесуваше 7,8 години. Вкупната оценка за квалитетот на животот и оралното здравје на испитаниците варираше во интервалот 1,93 ± 0,65, а просечната вредност кај субјектите со протетички конструкции за p> 0,05 (p = 0,19) беше нешто повисока во однос на субјектите без било каква протетичка изработка. Заклучок: Резултатот на GOHAI-12 во студијата имаше ниска вредност, помалку од 50 што покажа дека испитаниците беа со слабо орално здравје. Според резултатите од самооценувањето, имаше слаба до умерена перцепција за нивното оралното здравје. Потребен е интегриран пристап за да се постигне критично позитивно ниво на општото и оралното здравје кај геријатриските пациенти.

Published: December 2022

Correct positioning of the canines after their retraction is of great importance for the function, stability and esthetics. Aim: Two case reports were presented to compare the efficiency of two techniques for canine retraction, segmented mechanics using 0.017 x 0.025 TMA T-loop vs sliding straight-wire mechanics usingelastomeric chains. Material and methods: The first case describes orthodontic treatment with 0.017 x 0.025 TMA T-loop whereas the second case describes a 9 mm canine retraction using elastomeric chains. Results: Depending on the type of malocclusion both techniques for canine retraction can be used. Post treatment results showed canine retraction with good anchorage control and no mesial movement of the molars.Conclusion: Both techniques provide an optimum rate of tooth movement and none of the methods can be considered superior in terms of tooth movement or side effects, including rotation, tipping, root resorption, anchorage loss, as well as associated pain.

Developmental hip dysplasia includes a wide range of conditions such as subluxation, dislocation, hip instability, and teratological hip. The diagnosis was confirmed by clinical examination, ultrasound examination and anterior-posterior view radiograph (AP). Treatment varied depending on the patient's age and the degree of dysplasia: Pavlik harness, closed reduction, open reduction and corrective osteotomies. In this study 242 patients were included, of whom 198 were female patients and 44 male. All of the patients were treated with conservative treatment- closed reducation and spica casting. Left-sided dislocations were more common than right sided dislocations with predominance in the female patients. The main treatment in follow-up patients was closed reduction with or without adductor muscle tenotomy (m. add. longus). In cases with unsuccessful attempt of closed reduction, open reduction was performed with or without adductor muscle tenotomy. Depending on the residual dysplasia, patients were additionally treated with pelvic osteotomies (Salter 's inominate osteotomy), varus derotation osteotomy, valgus osteotomy, proximal femoral resection, and trochanter major transposition. 167 patients were treated with closed reduction and 3 with open reduction. The remaining patients were treated with closed reduction and additional surgery or with open reduction and additional surgery. Out of all treated patients, only 10 patients had recurrent dislocation of the hip, 7 female and 3 male patients. Closed reduction was performed again on two patients, and open reduction of the hip was performed on one patient. The average age of patients was 21.5 months. By presenting the cases in a period of 10 years, it was conclud that most cases were diagnosed later. Also, the standard closed reduction treatment was successful even after the first year in said patients. Depending on the residual dysplasia of the hip, in order to achieve better congruence of the joint, additional surgeries were performed.

Acinetobacter baumannii and Pseudomonas aeruginosa are commensal which commonly colonize humans. As a result of their ubiquitous nature, reservoirs in hospital environment and resistance to many antimicrobial agents they are responsible for hospital – acquired infections. Additionally treatment of these infections is difficult because of the ability for biofilm formation. Aim of the paper was to determine the association between biofilm formation on medical devices and antibiotic resistance profile, compared to respiratory samples in clinical isolates of Acinetobacter baumannii and Pseudomonas aeruginosa. Material and methods: The study comprised 50 clinical samples (36 from medical devices and 14 as а control group from respiratory secretions). Acinetobacter baumannii and Pseudomonas aeruginosa were identified by routine microbiological methods. Modification of the microtiter plate assay described by Stepanovic et al. was used to investigate the formation of biofilm. The antimicrobial susceptibility testing was performed according to EUCAST guidelines. Results: Of the 50 analyzed strains, 16 (32%) were non-biofilm producers, and 34 (68%) were producing biofilms. Out of these, 29 (58%) were from medical devices, and 5 (10%) from the control group. Acinetobacter baumannii showed biofilm formation in 19 (67.9%), of which 17 (60.7%) from medical devices, and 2 (7.1%) from control group. Pseudomonas aeruginosa produced biofilm in 15 (68.1%), of which 12 (54.5%) from medical devices, and 3 (13.6%) from the control group. Multidrug resistance was detected in 40 (80%). All strains of Acinetobacter baumannii were multidrug resistant (MDR). For Pseudomonas aeruginosa, 11 (73.3%) biofilm forming isolates were MDR, and 1 (14.2%) non-biofilm forming isolate was MDR. Conclusion: Biofilm production was higher in strains from medical devices. Eighty percent of isolates were MDR. This is a serious challenge for treatment of these hospital-acquired infections.
