Розглянуто експорт зернових продуктів, як ключовий фактор для економіки України. Процес дегідратації зернових продуктів є одним із важливих при перевалці сировини, в сьогоденні використовується конвективне сушіння з використанням енергії спалювання природного газу. Дослідження зосереджені на пошуку інноваційних методів зневоднення для підвищення ефективності цього процесу. Проведено аналіз літератури на сучасні методи дегідратації сировини, зокрема харчової та фармацевтичної, з акцентом на потенціал на комбінованих методів сушіння, зокрема з використанням мікрохвильового поля, що забезпечує швидку дегідратацію, збереження поживних речовин та покращення якості продукту. Побудовано параметричну модель для комбінованого процесу зневоднення з використанням комбінованої дії електромагнітного та відцентрових полів. Об’єктами експериментальних досліджень була кукурудза. Експериментальний стенд включав центрифугу та джерело електромагнітної енергії. Отримано кінетику зневоднення з використанням трьох режимів експериментальних досліджень. Аналіз експериментів показав, що підвищення частоти обертів центрифуги знижує енергетичні витрати, режим обробки сировини в мікрохвильовому полі при 25 секундах забезпечує ефективну дегідратацію без утворення водяної плівки, яка перешкоджає проникненню енергії. Експериментальні дослідження показали, що зневоднення кукурудзи у мікрохвильовому та відцентровому полях при потужності 4300 Вт/кг і частоті 1000-3000 об/хв дозволяє витратити лише 1,67…2.7 МДж/кг вологи, тоді як традиційні технології витрачають понад 4 МДж/кг. Стаття підкреслює перспективність використання мікрохвильового поля та відцентрових сил для покращення ефективності процесів дегідратації.

В статті розвинута термовологомеханіка сушіння харчових продуктів на основі систем диференціальних рівнянь тепло- та масопереносу та описані різні аналогічні процеси. Розглянута задача покращення процесу теплового сушіння продуктів у примусовому режимі, яка полягає у визначенні співвідношень між параметрами процесу: температурою сушильного агенту на кожній ступені, часом витримки, початковою температурою сушіння і початковою, і кінцевою вологістю продукту, які дозволять без зниження якості готового продукту провести процес з мінімальним сумарним часом сушіння при мінімальних енергозатратах. Побудовані ізотерми адсорбції та десорбції води в харчових продуктах, які залежать від вмісту води і температури. Показана крива десорбції, яка розділена на 3 зони. Зона 1 (0 ≤ 0,2): характеризується утворенням молекулярного моношару на поверхні продукту (сили Ван-дер-Ваальса між гідрофільними групами та молекулами води). Зона 2 (0,2 ≤0,6): Адсорбція молекул водню відбувається на вихідному моношарі або включенням молекул води капілярним шляхом. Зона 3 (> 0,6): вода, присутня в рідкому стані в порах матеріалу. Мікрокапілярна вода є безперервною фазою. Дана оцінка застосування моделі дифузійної теорії для біологічних матеріалів, які регулюються рівнянням дифузії Досліджено в даному контексті положення теорії капілярності в якій потік вологи визначається капілярними силами, а не градієнтом концентрації вологи. На основі випаровувально-конденсаційної теорії випаровування і конденсації розглянули як сполучний механізм перенесення маси та внутрішньої теплоти, де маса переходить у пароподібний стан, а теплота обмінюється з середовищем шляхом конденсації пари або випаровування води. Показані механізми перенесення вологи всередині харчових продуктів у формі твердого тіла.

Сушіння є одним з найбільш енерговитратних процесів в харчовій та переробній промисловості. Вчені та інженери багатьох країн постійно працюють над вдосконаленням технологій сушіння проводячи пошук нових способів видалення вологи з сировини та харчової продукції. Для традиційного, конвективного способу сушіння розроблено та впроваджено велику кількість його варіацій. Проте обмеження конвективного сушіння пов'язані з фізикою процесів тепло і масопередачі не дозволяють розраховувати на суттєве збільшення енергоефективності та продуктивності конвективних технологій сушіння. Одним з конкурентів конвективного способу сушіння є мікрохвильове сушіння, яке використовує відмінні від конвективного способу принципи підведення теплової енергії до вологи, що міститься в матеріалі. Технології мікрохвильового сушіння поступово переходять з розряду інноваційних високотехнологічних способів вологовидалення до розряду спеціалізованих але доступних виробнику процесів. В роботі представлено узагальнений аналіз мікрохвильового способу сушіння вологих матеріалів та його основних переваг. Розглянуто розвиток мікрохвильового способу сушіння шляхом його комбінування з фільтраційним сушінням. Приведено переваги такого комбінованого способу сушіння.

Зростання населення у світі та Європі, збільшення потреби в їжі та зростаюча тенденція не-м'ясного харчування, створюють умови для сталого попиту на рослинні білки. По амінокислотному складу білки соняшникового шроту перевершують інші рослинні білки і можуть використовуватися в харчових технологіях, що становить величезний практичний інтерес.
Соняшниковий шрот багатий поліфенольними сполуками, серед яких хлорогенова кислота, яка займає близько 70 % від інших поліфенолів. Хлорогенова кислота утворює комплекси з білками і її важко відокремити повною мірою.
Використання надкритичної екстракції з СО2 соняшникової макухи обмежено.
Мета дослідження: дослідити процес надкритичної екстракції СО2 та отримати з соняшникової макухи білковий концентрат нейтрального смаку і кольору з низьким вмістом поліфенолів.
Ядро насіння соняшника було віджато із застосуванням технології холодного віджиму (температура продукту не вище 45оС). Протестовано біомасу у вигляді подрібненої макухи (розмір частинок різних фракцій dч =1…5 мм) та пелюсток соняшникової макухи (пелюстки до 10 см). Екстракцію проводили чистим CO2, та з етанолом (96 %) як співрозчинником.
Досліджено кінетику при екстрагуванні соняшникової макухи в середовищі надкритичного СО2. Отримано білковий концентрат (вміст білку 56,2…57,2 %) високої якості з нейтральним запахом та кольором. Використання низькотемпературних режимів екстрагування дає можливість зберегти нативні властивості білку.
Вміст хлорогенової кислоти в сухому залишку: при екстракції чистим СО2 – 34мг/100 г; при екстракції зі співрозчинником – 14 мг/100 г.

Published: December 2024

Contracture of the shoulder joint is one of the complications that ccurs after rotator cuff repair. The aim of the work is to investigate and compare the results of conservative and surgical treatment of patients with persistent contracture of the shoulder joint 6 months after shoulder rotator cuff repair. Methods. We included 51 patients who had resistant contracture of the shoulder joint of varying grade within 6 months after the operation. Conservative treatment was performed in 27 patients, surgical treatment under arthroscopic control was performed in 24 patients. In our study, we assessed the function of the shoulder using the Constant Shoulder Score and VAS scales before the start of treatment (i.e., 6 months after first surgery) 3 and 6 months after the start of treatment (i. e., 9 and 12 months after first surgery). Results. 3 months after the start of treatment, in the group where surgery was performed, the average functional result according to the Constant Shoulder Score scale was better than in the group where patients were treated conservatively and ranged within (16.4 ± 5.9) points, while in the group with conservative treatment the average functional result was (28.1 ± 6.7) points (p = 0.048). 6 months after rotator cuff repair in the group with conservative treatment the average functional result according to the Constant Shoulder Score scale was (23.1 ± 7.1) points, while in the group where surgery was performed it was (12.1 ± 6.3) points (p = 0.03). Conclusions. Performing arthroscopy with removal of scars from the s houlder joint a nd s ubacromial s pace, s elective c apsulotomy, subacromial decompression and excision of the coracoid-brachial ligament in patients with resistant contracture of the shoulder joint, which persists 6 months after the rotator cuff repair, provides better average functional results according to the Constant Shoulder Score scale and a lower level of pain syndrome according to the VAS scale in 3 and 6 months after first surgery compared to patients who continued conservative treatment.

Published: December 2024

The defect in the formation and subsequent genesis of crossed ligaments manifests as knee joint instability and is accompanied by a range of consequences of congenital developmental disorders of the lower limbs. Objective. To analyze and summarize the knowledge and practical experience in treating children with knee joint instability due to congenital developmental disorders of the lower limbs at the Children’s Orthopedic Clinic of the State Institution «Institute of Spine and Joint Pathology named after Prof. M. I. Sytenko of the National Academy of Medical Sciences of Ukraine». Methods. A prospective study was conducted on patients treated from 2019 to 2024, with a retrospective control group (32 healthy children) treated from 2008 to 2019. Results. Surgical intervention was performed using the classical SUPER knee procedure. Our team identified shortcomings and therefore added the Yamamoto procedure, as well as a combination of the Yamamoto procedure and tibial tuberosity transfer to improve treatment outcomes. Additionally, to correct moderate axis deformities of the limb, the method of hemiepiphysiodesis using our patented metal construction and instrumentation was preferred. Adequate rehabilitation treatment is a key stage in restoring knee joint function, as it reduces the risk of complications such as joint contractures and stagnant vascular manifestations in the lower limbs. Conclusions. Early and high-quality surgical treatment allows for the prevention of knee joint instability and enhances its functional capabilities. The modifications made to the SUPER knee procedure have improved knee joint stability in the postoperative period compared to the classical technique, as evidenced by the absence of medial instability and a lower degree of anterior displacement. Comprehensive treatment increases the functionality of the knee joints and reduces further degenerative changes, thereby improving the patient’s quality of life.

Published: December 2024

Legg-Calves-Perthes disease (LCPD) has a poor outcome leading to disability and early onset of osteoarthritis. Patient aged less than 8 years have usually good prognosis and are usually managed conservatively. The primary goal is to achieve spherical and congruent femoral head to reduce the chance of further subluxation of femoral head and secondary arthritis of the hip. Methods. The study aimed to analyze the radiological and functional outcomes of group-A (LSA) and group-B (LSA and trochanteric epiphysiodesis) in cases of LCPD. Our study retrospectively analyzed 80 patients (45 in Group-A and 35 in Group-B) between 2008 and 2018, 63 patients were boys and 17 patients were girls. Patients who did not respond to the conservative treatment over the course of 6 months and patients with Caterall type-II and III were taken into the study. Radiological parameters like Center edge angle, sharp angle, medial joint space distance, epiphysis height ratio, acetabular coverage, neck-shaft angle, articulo-trochanteric distance was noted for comparing radiological outcome. Results. Most of the patients in both the groups were Catterall-III — 66.25 % and Catterall-II — 33.75 %. According to Stulberg classification, excellent outcome was seen in 22.2 % of group A patients & 37.1 % of group B patients. Similarly, 15.5 % patients in Group A and 5.7 % patients in Group-B had bad outcome. Radiological and functional assessments were evaluated preoperatively and postoperatively till skeletal maturity which showed significant improvement in Group-B. 4 (8.8 %) patients in group-A and 3 (8.5 %) patients in group-B developed non-union & graft resorption was seen. Conclusions. Lateral shelf acetabuloplasty along with trochanteric epiphysiodesis helps in improving the neck shaft angle, gait, containment of subluxated head and maintains its congruity along with physiological remodeling. We recommend this combined procedure in cases of LCPD to counter the complications of early-onset arthritis and femoral head subluxation.

Published: December 2024

According to various authors, in wartime, injuries to the limbs as a result of combat trauma account for 44 to 70 % of all musculoskeletal injuries. In approximately 80 % of wounded, gunshot bone fractures are characterised by the presence of a bone defect of varying size. Despite certain difficulties and complications in the treatment of bone defects, orthopedic surgeons have quite effective methods of treating this pathology. However, a promising area of treatment is the technology of manufacturing an individual implant using 3D-printing of the scaffolds of existing bone defects and double-plate osteosynthesis with autobone grafting. Objective. To present the possibilities of surgical treatment of wounded with bone defects of the limbs as a result of gunshot wounds. The preliminary results of surgical treatment of 2 wounded with diaphyseal bone defects due to gunshot wounds of the upper and lower extremities, who were treated in the trauma department of the Military Medical Clinical Centre of the Eastern Region in 2022–2024, were analysed. To improve the functional results of treatment, we proposed three stages of rehabilitation treatment and implemented appropriate rehabilitation measures. To replace bone defects, we used the «double-plating» method with autobone grafting and individual implants made by 3D-printing. The results of surgical treatment were evaluated by clinical, radiological and functional data. It was found that fixation with two plates in combination with autogenous bone grafting ensures stable fixation, which helps to consolidate the bone defect and restore the functional capacity of the limb, and the use of individual implants made by 3D-printing allows to replace the lost bone tissue, which leads to the restoration and preservation of the functional state of the damaged limb.

Russian Literature in Argentina: Translations and Contemporary Studies
Authors: Berri Marina , García Brunelli Florencia
Published: December 2024

The objective of this article is to delineate the principal domains of inquiry pertaining to Russian literature that have emerged in Argentina during the twenty-first century, and to examine the underlying factors that have shaped the evolution of these studies in Argentina. Firstly, the current framework within which Russian literature is studied in Argentina is discussed in general terms. Subsequently, the authors present the findings of various studies identified as the primary research areas, including identity, utopia and dystopia, studies of specific authors, translation studies, and the influence of Russian literature on Argentine literature, particularly on discussions of literary realism. In light of these findings, the authors consider the factors that contribute to the sustained interest in Russian literature in Argentina. One of the reasons for this is the position of both literatures and countries as peripheral to the European and North American literary canon. This makes the question of identity a particularly fertile area of research. Conversely, an additional point of convergence between the two literatures is the reflection on realism and its relationship with the social sphere. The interconnection between literature and society, whereby literature serves as a conduit for contemplating novel perspectives on societal structures, has led to a heightened interest in utopian and dystopian literature in Argentina.
Social and Personal Connections in Wine Drinking Culture: Emotive Diversity and Social Practices
Authors: Kalinina Alena
Published: December 2024

The depiction of alcohol and the act of drinking in artistic images is a common feature of literary works. This is indicative of the high social significance of alcoholic beverages in human life. The process of mastering these images by secular literature of the modern era was preceded by the appearance of alcohol in folklore and in Old Russian literature, where they were metaphorically interpreted under the influence of ritual and everyday experience. The images of beer, wine, and vodka that have emerged are imbued with a distinctive emotional quality and communicative significance. The genesis and metaphorisation of images of these drinks elucidate the distinction between the presence or absence of a particular beverage in a literary work. The process of metaphorisation is based on the communicative function of ritual alcohol. The methods of social topology, which consider the individual as a social entity and human interaction with objects as the formation of social space, permit the view that alcohol can be regarded as a mode of social interaction. Beer, wine, and vodka are the agents of this contact, facilitating diverse forms of communication and resulting in a range of outcomes. An examination of the historical development of alcohol consumption and its perceived ceremonial properties through the lens of social topology reveals how the characteristics of the context and occasion of drinking beer, wine, and vodka indicate various connections. Since antiquity, the ceremonial consumption of beer (mead) has been associated with the strengthening of kinship between drinkers, the equalisation and inclusion of individuals within a group, and the binding of social interactions to a specific national Christian calendar of holidays or social necessity. The reason and measure of consumption were limited by rituals of handling the cup. The consumption of grape wine in Russia indicated a high social status, typically associated with rulers such as tsars or princes, or diplomats. Grape wine acquired a sacred meaning, symbolising the blood of Christ, and connected believers with God through the ritual of the Eucharist. The semantic field of religion also encompassed secular wines. Vodka had a prototype in the form of bread wine, a strong drink obtained by distillation and used in taverns since the fifteenth century. The advent of this type of alcohol and the subsequent tax policy of taverns effectively destroyed the conditions required for ritual alcohol consumption. This resulted in a shift in the nature of the connection, whereby the ritual of “food kinship” was replaced by a more transient form of friendship for profit. An analysis of folklore texts from a handwritten songbook from the nineteenth century reveals that the use of these drinks as metaphors for human relations is based on the actor properties of drinking beer, wine and vodka. For example, good beer is associated with love, while bad beer is associated with dislike. The mention of vodka is indicative of a negative connotation.

Published: December 2024

Aim. To determine the efficacy of nonsteroidal anti-inflammatory drugs in preventing the development of pancreatitis following endoscopic retrograde interventions.

Materials and methods. The study enrolled 865 patients who underwent transpapillary interventions for various hepatopancreatoduodenal diseases from 2019 to 2023. Patients in the main group (n = 470) were additionally prescribed Diclofenac suppositories (100 mg) 20–30 minutes prior to the procedure.

Results. In the main group, acute post-ERCP pancreatitis developed 1.8 times less frequently than in the control group. Nonsteroidal anti-inflammatory drugs reduced the incidence of acute post-ERCP pancreatitis by 3.6% (p = 0.006).

Conclusion. Nonsteroidal anti-inflammatory drugs decrease the incidence of acute post-endoscopic retrograde cholangiopancreatography (post-ERCP) pancreatitis. Regardless of their application, additional measures for preventing complications are required. The role of nonsteroidal anti-inflammatory drugs in preventing complications following endoscopic retrograde interventions warrants further research in larger patient groups.

Aim. To analyze the effectiveness of transjugular intrahepatic portosystemic shunt in complicated portal hypertension of cirrhotic origin aggravated by portal vein thrombosis, and to assess the portal decompression achieved through the reduction in the portosystemic pressure gradient.

Materials and methods. In the period of 2017–2024, transjugular intrahepatic portosystemic shunt was performed on 26 patients with liver cirrhosis and portal hypertension complicated by portal vein thrombosis. Mortality, recurrence rate of variceal bleeding, shunt thrombosis, rethrombosis of the portal vein, and overall survival were analyzed.

Results. All patients exhibited a decrease in portal vein pressure from 36.0 ± 3.4 mmHg to 21.9 ± 1.5 mmHg (t = 3.77, p < 0.001) and in the portosystemic pressure gradient from 28.5 ± 3.1 mmHg to 11.5 ± 1.1 mmHg (t = 5.17, p < 0.001). The maximum duration of follow-up accounted for 78 months. The six-week mortality rate comprised 7.7%, 8 patients (30.8%) died within one year. All patients underwent surgery due to a high risk of bleeding. 14 patients remain under observation.

Conclusion. Achievable portal decompression is considered effective in terms of reducing mortality and prolonging the non-transplantation period. Long-term anticoagulant therapy is found mandatory. The shunting procedure should be complemented by selective embolization of the inflow pathways to the esophagogastric varices.

The effect of sodium bicarbonate (SB) supplementation to fish feed on the quality characteristics of rainbow trout (Oncorhyncus mykiss) under post-harvest cold storage conditions was investigated in this study. Rainbow trout fed with 0, 1M, 2M and 3M SB supplemented diets for 21 days before harvesting were stored at 4°C. The highest post-harvest pH level was observed in the group fed with 2M and 3M SB. TVB-N value was found between 14.88-15.68 mg/100g in fish fed with 1M, 2M and 3M SB supplemented diets, while it was determined as 20.14 mg/100g for the control group. At the beginning of storage, similar TBARs values were observed in all groups; however the increase in TBARs in the groups fed with SB supplemented feeds was slower than in the control. Sensory scores of trout fed with SB supplemented diets at the beginning of storage were higher than those of the control group. However, no difference was determined between the groups regarding shelf life (13 days). The best texture scores were observed in the 3M group throughout the storage period. Therefore, it can be concluded that SB addition to pre-harvest rainbow trout feeds can be used as a feed supplements to improve fish flesh quality.
Chemicals and Amounts Used Against Fungal Infections During Trout (Oncorhynchus mykiss) Egg Incubation Period
Authors: Doğan Mustafa
Published: December 2024

This review examines the effectiveness and dosages of chemical and herbal disinfectants used against fungal infections encountered by trout (Oncorhynchus mykiss) eggs during incubation. Formalin, potassium permanganate and copper sulfate are prominent chemicals among disinfectants. Formalin provides effective antifungal treatment when used in concentrations of 1000-2000 ppm, but it can have toxic effects in excessive doses. Potassium permanganate can control fungal pathogens when applied at concentrations of 1-5 ppm, but it can have negative effects on fish at high doses. Copper sulfate helps prevent fungal infections when applied at a dosage of 0.5-1 ppm. Herbal disinfectants include tea tree oil, thyme oil and garlic extracts. It has been observed that tea tree oil and thyme oil can be effective against fungal infections when used at 0.5-1%. It has been determined that garlic extracts can reduce fungal infections when used at 1-2% on trout eggs. Plant-based disinfectants are compounds that generally have lower toxicity and may reduce adverse environmental impacts, but their effectiveness may be variable compared to chemical disinfectants. Future research should focus on evaluating the effectiveness of chemical alternatives and developing more sustainable methods.

Published: December 2024

This article examines the perceptions of fourth-year undergraduates enrolled in the Biological Sciences program at a public university in Mato Grosso do Sul, Brazil, concerning the relationships between Science, Technology, and Society (STS). Data were gathered through an online survey administered to 12 students in the first semester of 2022, which were subsequently categorized and analyzed using content analysis techniques. The findings reveal that students acknowledge the role of environmental, social, historical, political, and economic factors in shaping the epistemology of Science and Technology. Nonetheless, the complexity of these interactions has led to the emergence of doubts, misconceptions, or partial understandings that need to be addressed. In this context, the role of STS Education and Environmental Education is emphasized as crucial educational strategies aimed at correcting misconceived perceptions about the nature of Science and Technology. Additionally, these educational approaches seek to foster critical engagement in both individual and collective decision-making processes relevant to the application of Science and Technology, particularly with regard to socio-environmental sustainability and in response to the challenges posed by the current climate emergency.

Published: December 2024

From the most straightforward kind of technology—audiovisual learning—to the application of artificial intelligence in education, technology has been used in education for over 20 years. Despite the growing popularity of AI-based learning media technology, there is still a dearth of reliable empirical data about its effects on student achievements. This meta-analysis aims to investigate the impact of intervention time and combine findings from several studies to paint a more comprehensive picture of the usefulness of AI media in education. In this study, a meta-analysis design is employed in quantitative research. The Publish or Perish tool gathered secondary data from published papers using the Scopus database and Google Scholar—data analysis for group contrast meta-analysis data using the R software. The study's findings demonstrate how using AI-based learning resources greatly impacts students' academic performance. P value total effect size and three moderator variables (continent, gained achievement, and intervention duration < 0.05) show that the aggregate value of the summary effect in AI-based learning media, which integrates technology products with software, web programs, augmented reality, and gamification in increasing student achievement from elementary school to tertiary level from 2019 to 2024, is still providing significant influence. Thus, artificial intelligence (AI) should be used more extensively in preparing learning media to maximize students' academic and non-academic successes.

Published: December 2024

Given that students are and will continue to be in constant interaction with statistical data throughout their lives, they must be equipped to read, understand, and interpret such data. As a result, engaging in statistical thinking becomes essential. Statistical thinking can be defined as viewing the statistical process holistically in order to comprehend its underlying purpose. The aim of this study is to investigate eighth-grade students’ performance on tasks related to measures of central tendency, and to analyse their statistical thinking processes in detail. This research was designed as a case study, with tasks developed by the researchers focusing on measures of central tendency used during the data collection phase. These tasks were analysed within the framework of the M3ST (Middle School Students' Statistical Thinking), and the students' statistical thinking levels were identified. Concurrently, the solution strategies employed by the students were examined, as well as their performance in solving problems related to measures of central tendency. The analysis revealed that the students' statistical thinking was predominantly at level 3 or level 4 for the components of organizing and reducing data, respectively, while it was at level 2 for the components of representing data and analysing and interpreting data. It was found that the participants possessed procedural knowledge regarding measures of central tendency but struggled to provide explanations or draw inferences about the concepts. Moreover, most of the participants appeared to lack a deep understanding of the fundamental concepts of measures of central tendency. These findings are discussed in the context of the existing literature.

Published: December 2024

The integration of English into the education domain continues to expand steadily. Language policies in educational institutions are shaped according to the English requirements of respective countries. With the recognition of English as a lingua franca, it has taken on a significant role as the medium of instruction (EMI) in Turkish universities, with an increasing number of programs now being offered in English. For higher education institutions aiming to improve their rankings, establish a strong reputation, and enhance visibility, English is a critical factor. As a result, many opt to provide undergraduate programs in English. This study aims to determine the attitudes of lecturers toward full EMI programs. A qualitative research design was employed, with data gathered through semi-structured interviews with lecturers and classroom observations. The sample was selected using purposive sampling to ensure that participants had substantial experience with EMI. Thematic analysis was used to analyze the data, identifying key themes and patterns. Despite the inherent challenges of EMI, the findings revealed that lecturers hold positive attitudes towards EMI. Additionally, they emphasized the need for short-term, context-specific professional development opportunities focused on both language proficiency and pedagogical skills for EMI. These findings offer valuable insights for improving the overall quality of EMI and for guiding university policies to better meet the evolving needs of EMI programs.
Требования к участникам закупок для обеспечения государственных и муниципальных нужд: законодательные новеллы
Authors: Сюкияйнен Лика
Published: December 2024

В статье анализируется обоснованность новых требований к участникам закупочных процедур, установленных Федеральным законом от 5 апреля 2013 г. № 44-ФЗ «О контрактной системе в сфере закупок товаров, работ, услуг для обеспечения государственных и муниципальных нужд». Проведено сравнение с ранее действовавшими требованиями, установленными Федеральным законом от 21 июля 2005 г. № 94-ФЗ «О размещении заказов на поставки товаров, выполнение работ, оказание услуг для государственных и муниципальных нужд». Законом № 44-ФЗ установлены обязательные и дополнительные требования. Отдельно проанализировано каждое новое обязательное требование к участникам. Автором проведен анализ возможности подтверждения соответствия на практике новым требованиям, оценена судебная и административная практика по вопросу обоснованности установки обязательных и дополнительных требований. Выявлено, что дополнительные требования признавались неправомерными, если они не были обоснованы и не влияли на существо правоотношений. При этом отсутствие обязательных требований в конкурсной документации является незаконным. Проведен анализ соотношения новых требований к участникам в свете введения в Трудовой кодекс Российской Федерации ст. 19.1, в соответствии с которой введен формальный запрет на заключение работодателями гражданско-правовых договоров при наличии фактически трудовых отношений с исполнителями. Проанализированы новые статьи Кодекса об административных правонарушениях, в частности, ч. 2 ст. 5.27, а также ч. 4 ст. 5.27, вступившие в силу с 1 января 2015 г. Указаны риски и последствия для участников в случае несоответствия требованиям. Автор приходит к следующим выводам: установление новых требований к участникам закупочных процедур не всегда представляется обоснованным, особенно учитывая наличие у заказчика более широких полномочий в сфере расторжения контракта с поставщиком при несоблюдении им требований. Некоторые требования нуждаются в более точной законодательной формулировке, поскольку эффективная практика их реализации в нынешнем виде остается под вопросом.
