Published: May 2024

In this study, pure and hBN-doped ZnO nanoparticles were synthesized by sol–gel method. ZnO–hBN nanoparticles were mixed with pure aluminum powders and samples were prepared using powder metallurgy processing parameters. It was observed that Al, ZnO, and hBN nanocomposite particles formed homogeneously. With the addition of ZnO–hBN, significant changes occurred in hardness, wear, and friction coefficient values compared to pure Al samples. The highest hardness value in the samples is mesh. It was obtained as 105 HB in 10 wt.% hBN added sample. In the wear tests, it is seen that the wear resistance is seven times higher in the 1 wt.% hBN added sample compared to the pure Al sample, while the friction coefficient decreases with the increase of the hBN additive.

This study aimed to analyze the conventional ratio values of knee flexors and extensors obtained using an isokinetic dynamometer (IsoRatio), an adjusted torque test of 5RM (Ratio5RM), and absolute values of 5RM (Ratio5RML). Fifteen male volunteers (28.47 ± 5.78 years; 78.30 ± 6.59kg; 1.79 ± 0.65m) performed a 5RM test on leg extension and leg curl machines. The volunteers executed knee flexion and extension movements at 60°/s angle speed without significant differences between protocols. Regression analysis showed that the Ratio5RML correlates with the isokinetic reference ratio (r=0.649; p=0.009). The result of the paired t-test showed no significant difference between the means of the isokinetic ratio and the ratio predicted by the equation. The results of the present study suggest that the 5RM test performed with isoinertial machines can be used to estimate conventional ratio and identify imbalance between the knee flexors and extensors muscles.

Published: May 2024

Background: Meckel's diverticulum (MD), a true diverticulum with all 3 layers, is the most common congenital anomaly of the gastrointestinal tract is due to the failure of the obliteration of the vitellointestinal duct during the 5th to 9th week of gestation life. MD can present as haemorrhage, obstruction, diverticulitis, intussusceptions or perforation. Here we present a case of strangulated Littre's hernia in the right inguinal region. Case report: A 19-year-old male presented with a right groin swelling of 1-month duration. His swelling was not reducible for the past 1 day. He had associated vomiting of 1-day duration. On examination he was febrile and with a heart rate of 96 per minute. His groin examination revealed a 6 x 4 cm swelling which was tense and tender with absent cough impulse. His Chest X-ray and abdomen were within normal limit. His blood investigation was within normal limits except for a leucocytosis. A provisional diagnosis of strangulated inguinal hernia was made and patient was taken up for surgery. A right inguino-scrotal incision was made. The hernia sac was opened at the fundus. 5ml of toxic fluid was let out. The content was a gangrenous Meckel's Diverticulum which was 8cm in length and about 60 cm from ileocaecal junction. Resection of the gangrenous MD was done with end-to-end anastomosis of the ileum. Postoperative period was uneventful and he was discharged on the 9th post-operative day. Conclusion: Meckel's Diverticulum is one of the rare contents of the hernial sac. Diagnosis is usually intraoperative. Management includes resection of the diverticulum
Safety profile and adherence to treatment with ocrelizumab in multiple sclerosis – long-term observations
Authors: Pokryszko-Dragan Anna
Published: May 2024

Among the available disease modifying drugs used in the treatment of multiple sclerosis, there is an increasing relevance of high-efficacy therapies recommended for early use to control the disease activity effectively. In the course of treatment, efficacy as well as safety measures of high-efficacy therapies have to be regularly evaluated. Ocrelizumab, an anti-CD20+ antibody, is the only high-efficacy therapy approved for the treatment of both relapsing-remitting and primary progressive type of multiple sclerosis. Consequently, the drug can be used in a wide population of multiple sclerosis patients. Recently, the cumulative data have been acquired from 10-year follow-up of ocrelizumab use in clinical trials and real-world evidence in as many as 300,000 patients with multiple sclerosis. Based on these data, the general safety profile of the drug has been reviewed (considering the risk of major adverse events, including infusion-related reactions, infections and malignancies), along with specific aspects associated with vaccines and pregnancy/post-partum period. Moreover, the indices of adherence and persistence in long-term treatment with ocrelizumab have been analysed, together with their potential contributing factors. The above data indicate that treatment with ocrelizumab has a beneficial safety profile and is well-tolerated by patients with multiple sclerosis, which supports the choice of ocrelizumab as a therapeutic option. Ongoing clinical and observational trials and registries will provide further data on the safety of the drug, which would allow an update of recommendation in this field.
New directions in ocrelizumab therapy in multiple sclerosis: higher doses and subcutaneous therapy
Authors: Selmaj Krzysztof , Selmaj Igor
Published: May 2024

Ocrelizumab is the first anti-CD20 monoclonal antibody approved for the treatment of relapsing and primary progressive multiple sclerosis. Ocrelizumab is administered intravenously (i.v.) at a dose of 600 mg every six months. It is a highly effective drug strongly inhibiting inflammatory changes in the central nervous system, which nearly completely prevents the development of new active magnetic resonance imaging lesions and clinical relapses. Pharmacokinetic studies and data from post hoc analyses of ocrelizumab pivotal studies suggest that a higher dose than the current dose level might have a stronger therapeutic impact. These results revealed that higher ocrelizumab exposure dependent on lower body mass correlated with increased B cell depletion and reduced risk of disability progression independent of relapse activity (PIRA). In addition, higher ocrelizumab exposure showed a correlation with decreased development of new and enlarging T2 magnetic resonance imaging lesions. Two randomised studies are currently under way to compare the efficacy and safety of the standard i.v. dose of 600 mg versus higher doses (1,200 mg or 1,800 mg) in multiple sclerosis patients. Another new direction in the development of ocrelizumab therapy in multiple sclerosis is subcutaneous (s.c.) drug administration. Recent data from the OCARINA study revealed that s.c. ocrelizumab was not inferior to the i.v. administration with respect to pharmacokinetics, magnetic resonance imaging activity, and clinical relapses. The safety of s.c. ocrelizumab was found to be comparable to the i.v. form, with a higher rate of mild local injection reactions.

A TRANSIÇÃO DA CURIOSIDADE INGÊNUA PARA EPISTEMOLÓGICA CRÍTICA E SUA IMPORTÂNCIA NO CONTEXTO DA PEDAGOGIA LIBERTADORA FREIRIANA
Authors: Ueno Yasmin , Natal MUraro Darcisio
Published: May 2024

Este artigo analisa a importância da curiosidade epistemológica crítica na perspectiva da filosofia da educação de Paulo Freire pretendendo responder à seguinte problemática: qual o papel da curiosidade na educação dialógica e libertadora de Paulo Freire? Na perspectiva desse autor, o agir educativo criativo e criador possibilita aos estudantes as condições de admirar, perguntar e dialogar crticizando os seus saberes. Freire nos dispõe em seus escritos que o ciclo gnosiológico promove a transição da curiosidade ingênua para a epistemológica crítica. Neste sentido, o autor denuncia as práticas da educação bancária que rechaçam e coíbem a investigação crítica por entender os estudantes como depósitos de conteúdo a ser memorizado. Em contraposição à educação bancária ele concebe a educação dialógica, libertadora e problematizadora que pretende a superação do ensino tradicionalista bancário visando o desenvolvimento de sujeitos epistemologicamente críticos e curiosos. A partir de uma metodologia de estudo bibliográfico que contempla a revisão das principais obras de Freire, este trabalho tem como objetivo investigar a importância da curiosidade epistemológica crítica na educação, conceito escolhido pela sua vinculação com toda a metodologia freiriana. A partir das análises realizadas, conclui-se que uma educação voltada para o estímulo da curiosidade epistemológica crítica, desperta tanto nos educandos quanto nos docentes, uma leitura de mundo ampliada, uma consciência crítica voltada para a transformação da realidade e um efetivo crescimento do ser mais justo, solidário e humano.

Published: May 2024

In this study, a novel star-shaped antenna with partial ground plane was designed to achieve ultra-wideband
(UWB) communications. To create the wireless local area network band notch (5.71-6.02 GHz), the ground plane contained two pairs of split ring resonators that were symmetrically arranged. The split ring resonators were placed on the patch to obtain a C-band notch (4.54-4.6 GHz). A circular slot was added to the patch in order to obtain an X-band notch for satellite communications (6.44-7.12 GHz). The suggested antenna is a strong option for a variety of UWB applications due to its excellent performance in triple notched bands, consistent gain, and radiation patterns in the operating bands.

Published: May 2024

In this study, flexible cellulose acetate (CA)/polyaniline (PANI) films, consisting of PANI and CA, were produced using a solution-casting production process. Then, these films were irradiated using a handmade cold cathode ion device with argon fluences of 2 × 1017, 4 × 1017 and 6 × 1017 ions/cm2. The SRIM program was used to investigate the ion penetration depth, ion distribution in the composite and the energy stopping loss. Moreover, the Fourier transform infrared spectroscopy technique was used to identify changes in the treated CA/PANI. The ultraviolet–visible spectroscopy technique was used to show the impact of the argon beam on the optical characteristics of CA/PANI composite films. The oscillation energy (E 0) dropped from 8.88 eV for CA/PANI to 7.83, 6.42 and 5.19 eV after exposure to 2 × 1017, 4 × 1017 and 6 × 1017 ions/cm2. The results showed that the ions altered the optical characteristics of the CA/PANI samples, which allow application of these irradiated CA/PANI films in optoelectronic devices.

Published: May 2024

Rapid urbanization brought serious socio-economic and environmental problems in many cities around the world, particularly in developing countries like Yemen. Urban "sprawl", a synonym of rapid and unplanned urban growth, is considered an obstacle for sustainable development, which causes serious long- and short-term problems, such as extreme infrastructure expenses, economic inefficiency, environmental destruction, and social instability. This is the case of Taiz City, the third largest city in Yemen, which is facing a huge challenge to manage the spatial extension of its built-up area at the expense of the reduction of natural resources and environment. This study aims to investigate urban growth process in Taiz City, focusing on urban sprawl and agricultural land-use change during 1981–2022. The data used are high resolution geospatial data, which are the topographic map for 1981 and Google Earth (GE) images for 2003, 2012, and 2022. The methodology adopted was manual digitizing using Geographic Information System (GIS) software to extract urban land use features from the images of the different dates. Four land-use maps were produced and used for calculation the urban sprawl and land-use changes. The urban expansion rate and patterns were also identified in three phases: 1981–2003, 2003–2012, and 2012–2022. The results show that the built-up area increased six times from 6.2 km2 in 1981 to 34 km2 in 2022, while the agriculture area decreased by 77% from 18 km2 in 1981 to 4.2 km2 in 2022. The urban sprawl in Taiz covered about 75% of its municipal area and extended to the agricultural and rural areas. The sprawl index (USI) is measured to be 5.4%, indicating a high degree of sprawl in Taiz. There is no open space left for future development, and the water resources are at risk of population and depletion. The study demonstrated that informal and haphazard expansion must be controlled, a development strategy should be prepared, so that sustainable urban growth can be achieved. The results of this study could be used as a decision support tool for urban management activities. The vector layers produced by this study could provide the required input data for the future urban modeling of the city.

Bu çalışmada hayvansal atık yağlarının (sığır ve koyun) biyodizel üretiminde hammadde olarak kullanılmasında teknik ve ekonomik analiz incelemesi kimya ve süreç mühendisliği çerçevesinde yapılmıştır. Hammadde kaynağı olan hayvansal atık yağlarının belli bir kısmının biyodizel üretiminde kullanılması durumuna göre üç farklı ulaşılabilirlik faktörü (%10=0,1; %50=0,5; %100=1,0) göz önüne alınmıştır. Hesaplamalar sonucunda 2030 yılında %100 ulaşılabilirlik faktörüne göre potansiyel biyodizel üretim miktarı yaklaşık 112 bin ton ve bu miktardaki biyodizelin net değeri yaklaşık 2,9 milyar TL (2022 yılı TL kuru esas alınarak) olarak hesaplanmıştır. Ayrıca, 2010-2021 yılları arasında hayvansal atık yağları %10, %50 ve %100 oranlarında ulaşılabilirlik faktörleri ile toplanıp biyodizel üretiminde kullanılsaydı; Türkiye’nin biyodizel üretiminin ortalama olarak %27, %135 ve %270’inin karşılanabileceği hesaplanmıştır. Bunun sonucunda eğer hayvansal atık yağlarından biyodizel üretilmiş olsaydı, Türkiye’nin hâlihazırdaki biyodizel üretim kapasitesinin çok üzerinde bir değerlerde (takribi üç katına kadar) olacağı bulunmuştur. Ayrıca, bu çalışmada biyodizelin CO2 azaltmaları hesaplanmıştır. Son olarak, teorik olarak hesaplanan karbon dioksit (CO2) emisyonu azaltmaları, literatürden bulunan ulaştırma ile meydana gelen CO2 emisyon miktarları arasında oran kurulmuştur. 2010-2021 yılları arasında %10, %50 ve %100 oranlarında ulaşılabilirlik faktörlerine göre Türkiye’nin CO2 emisyonu azaltma miktarları ortalama yaklaşık %0,029, %0,146 ve %0,292 olarak hesaplanmıştır.

İçerisinden direk hava akışı metoduyla soğuyabilen takılabilir modüllerde kanatçık yükseklik etkisinin sayısal ve deneysel olarak incelenmesi
Authors: Tekin Yusuf , Bilgili Muhittin
Published: May 2024

Gerçekleştirilen bu çalışmada, yüksek güç tüketen elektronik bileşenlere sahip baskı devre kartlarının, modül seviyesinde soğutma yöntemlerinden biri olan modül içerisinden hava dolaştırılarak (AFT-Air Flow Through) soğutma yöntemi incelenmiştir. Yöntemin uygulanması aşamasında, ANSI/VITA 48.8-2017 standarttı referans alınmıştır. Bu yöntem, elektronik bileşenlerin soğutma havasıyla direk teması olmadan modül seviyesinde soğutulmasına imkân sunmaktadır. Soğutmanın gerçekleştirilebilmesi için modül üzerindeki kısıtlı bir alana kanatçıkların yerleştirilmesi gerekmektedir. Fakat standart içerisinde, üç farklı adım aralığı altında kısıtlı bir alana sahip olan modül içerisine konumlandırılacak kanatçıkların olabilecek maksimum kanatçık yükseklikleri ile ilgili detaylar kullanıcılarının kendi soğutma ihtiyaçlarına göre belirlemesi için herhangi bir detay verilmemiştir. Standart içerisinde eksik olan bu bilgilere referans olması amacıyla bu çalışma yapılmıştır. Çalışma kapsamında, bu tarz elektronik soğutma uygulamalarında yaygın olarak kullanılan dikdörtgen kesitli plaka tipi kanatçık kullanılmıştır. 1 inç, 1.2 inç ve 1.5 inç adım aralığına sahip takılabilir bir modül üzerinde oluşabilecek maksimum kanatçık yüksekliklerine göre, modülün soğutma performansında ve akış dinamiklerinde oluşacak değişimleri gözlemlemek için üç boyutlu sayısal analiz çalışmaları yapılmıştır. Sayısal analiz çalışmaları FLOEFD paket programı kullanılarak gerçekleştirilmiştir. Isı emici görevindeki takabilir modül, 3U (100*1600mm) biçim faktörüne sahip bir baskı devre kartına uygun olacak şekilde tasarlanmıştır. Modülün termal direnç, basınç düşümü ve ortalama ısı transfer katsayılarındaki değişimler üç farklı kanatçık yüksekliği altında incelenmiştir. Analizlerin gerçekleştirildiği sayısal modeli doğrulamak amacıyla 1.2 inç adım aralığına sahip ve üretimi gerçekleştirilmiş bir modül üzerinde deneysel çalışmalar yapılmıştır. Modülün elektronik bileşenlerin temas ettiği yüzeyine sürekli 100 W ısı verilmiştir. Modülün hava giriş tarafında 25°C giriş sıcaklığında ve 2000 ≤Re ≤ 11000 arasında hava kullanılmıştır. Sonuç olarak, modül üzerinde kanatçık yüksekliğinin arttırılması ile sağlanan ısı transfer alanın arttırılmasına yönelik etkiler, modülün termal performansına olumlu katkı sağladığı anlaşılmıştır. Aynı giriş hızlarında en yüksek kanatçık yüksekliğine sahip 1.5 inç adım aralığına sahip modül üzerinden %60 oranında daha fazla kütlesel debi geçirilebileceği gözlemlenmiştir. Deneysel çalışımalar ile elde edilen sıcaklık verileri ile sayısal simülasyonlar sonucunda elde edilen sıcaklık verileri arasındaki sapmalar %5.4 ile %7.5 arasında değişmektedir.

Authors: Ketizmen Gökçe
Published: May 2024

Mimarlık eğitiminde öğrenme süreçleri, motivasyon ve kişilik özelliklerine odaklanan deneysel bir keşif olan bu araştırmanın temel odağı, bu üç kavramı tanımlamak ve mimarlık öğrenimi bağlamında bu olguları değerlendirmek için uygun envanterleri belirlemektir. Mimarlık eğitiminde, bilgiyi alma ve işlemedeki tercihler ve özellikler bağlamında öğrenme süreci, bilgi ile görsel ve sözel iş birliği kapasitesi ile ilişkilidir. Mimarlığın çok boyutluluğunun yanı sıra diğer alanlardaki çok sayıda ortak metodoloji ve konudan farklılaşma kabiliyeti de eğitim üzerinde önemli bir etkiye sahiptir. Bu nedenle mimarlık öğrencileri, mimarlık disiplininin tek bir yönüne dayalı öğrenme süreci gruplarına kolayca ayrılamaz. Bu çalışma, Öğrenme Süreçleri Envanteri (ILP), Beş Büyük Envanteri (BFI) ve İş Tercihi Envanteri (WPI) aracılığıyla 150 son sınıf mimarlık öğrencisi arasında öğrenme süreci, kişilik ve motivasyon arasındaki ilişkiyi incelemeyi amaçlamaktadır. Sonuçlar, son sınıf mimarlık öğrencileri arasında birincil öğrenme yaklaşımının, vicdanlılık, keyif alma ve dış ödüllerle güçlü bir şekilde bağlantılı olan detaylı düşünme süreçleri olduğunu ortaya koymuştur. Bulgular, mimarlık öğrencilerinin öğrenme yaklaşımları ile ilişkili motivasyon ve kişilik özelliklerinin belirlenmesinin iyi bir eğitim müfredatı geliştirirken anlaşılmasının önemini vurgulamaktadır.

Unjustified Enrichment as a result of Turnover of Objects of Information Law
Authors: Pavlov A. A.
Published: May 2024

Not being an object of civil rights (Article 128 of the Civil Code of the Russian Federation), information has acquired objective marketability that does not limit itself, due to its value for certain persons, to using the construction of a contract for the provision of paid services for the legal regulation of emerging legal relations. The paper examines the legal nature of information and its historical and modern regulation, examines cases of illegal access to information and its use for the benefit of an unscrupulous person and suggests the possibility of applying the institute of unjustified enrichment by analogy. It is proved that the use of actio de in rem verso as an institution of unfair enrichment is the most appropriate for regulating the legal relationship under study. It is proposed to use the named institution up to the proposed reform of civil legislation in order to give information the properties of a full-fledged object of civil rights. It is argued that the reform of civil legislation regarding the inclusion of information in the objects of civil rights is long overdue and is predetermined by the objective development of the information society. Moreover, the expansion of digitalization and digital transformation of participants in civil law relations, including the state, leaves no doubt that such changes are relevant, and the courts, as soon as such an opportunity arises, need to begin applying new legislation in this regard.
On the question of the importance of trust in criminal procedure regulation
Authors: Smirnova I. G. , Sofijchuk N. V.
Published: May 2024

The article is devoted to the phenomenon of trust in criminal proceedings. By analyzing the criminal procedure form and its current state, the authors conclude that the problems inherent in it at the present stage in the form of increasing transformation, formalization, overload of rules, conditions and grounds can be overcome by referring to the genetic Russian code, which is based on ethical and moral values, a worthy place among which is occupied by trust. The paper reveals the essence of two areas of trust: vertical trust as an indicator of the legitimacy of government and state institutions and emphasizes that currently the court and the police are institutions with a negative level of trust in Russian society. In relation to horizontal trust as trust in another subject, participant in public relations or to an object, the work analyzes coercive measures, the admissibility of evidence, challenges, as well as the institution of representation.
Witness immunity in criminal proceedings: from theory to practice
Authors: Markova T. Yu.
Published: May 2024

The Constitution of the Russian Federation and the Code of Criminal Procedure of the Russian Federation establish a provision called witness immunity. This is a right, the use of which allows a participant in the process not to harm himself and his close relatives with his words or actions. This right is granted to many participants at all stages of criminal proceedings. Ensuring the implementation of the right to witness immunity is entrusted to state bodies and officials conducting criminal proceedings (investigator, investigator, prosecutor and court). The article analyzes the provisions on witness immunity contained in the Constitution of the Russian Federation and the Code of Criminal Procedure of the Russian Federation for their compliance. It is stated that Art. 51 of the Constitution of the Russian Federation has a broader content than paragraph 40 of Art. 5 of the Code of Criminal Procedure of the Russian Federation, which requires bringing the norms of the Code of Criminal Procedure of the Russian Federation into conformity with the Constitution of the Russian Federation. It is concluded that the procedure for clarification and implementation of the right to witness immunity does not have sufficient legal regulation in the Code of Criminal Procedure of the Russian Federation, which leads to certain violations in the work of the preliminary investigation bodies, but is partly compensated by clarifications of the Constitutional Court of the Russian Federation and established judicial practice.
On the issue of changing the charge during the preliminary investigation
Authors: Antonovich E. K.
Published: May 2024

Stopping the prosecution of an innocent person is just as important as filing charges. Therefore, already in pre-trial proceedings, it is so important to formulate in detail not only the provisions regulating the procedure for filing charges, but also the features of changing it. However, after the charges are filed, the collection of evidence continues.

 This leads, in some cases, to amend, supplement a previously brought charge, and sometimes make a decision to terminate it in part. Meanwhile, the legislative regulation of this procedure gives rise to discussions both among law enforcement officials and in the scientific community.

 Digitalization, as well as modern legislative structures for bringing charges and interrogation, provided for in the legislation of some foreign countries, seem to be of interest and can be taken into account in the search for new vectors in the search for ways to change the charge.
Russian Criminal Procedure to Protect the Rights and Legitimate Interests of Entrepreneurs
Authors: Sheremetyev I. I.
Published: May 2024

The article discusses changes in Russian criminal procedural legislation related to criminal proceedings on crimes in the economic sphere committed by entrepreneurs in connection with their entrepreneurial or other economic activities. It is noted that these changes are due to the general policy of the state aimed at increasing the economic activity of the population and accelerated economic development of the country as a whole. In this regard, the author provides critical statements by the country’s leaders regarding the current law enforcement practices. The article consistently sets out individual institutions of criminal procedural law affected by these changes. Thus, the features of initiating criminal cases for certain crimes in the economic sphere classified as cases of private-public prosecution are described. The general rules for conducting investigative actions, including those related to the seizure of electronic storage media in cases of this category, are described. Considerable attention is paid to the selection of preventive measures against entrepreneurs and general restrictions on the use of detention against them. Special grounds for termination of criminal prosecution of entrepreneurs in connection with their compensation for damage are described. The author notes that the process of improving legislation in this area is far from complete and will continue depending on the needs of practice.
Limits of Judicial Control at the Pre-trial Stages of the Criminal Process
Authors: Dvoryankina T. S.
Published: May 2024

The article examines the issues of the limits of judicial control in accordance with Art. 125 of the Code of Criminal Procedure of the Russian Federation at the pre-trial stages of criminal proceedings. The author concludes that the court, verifying the legality and validity of the actions (inaction) and decisions of the investigation body in accordance with Art. 125 of the Code of Criminal Procedure, has no right to invade the investigation process and establish the factual circumstances of the case by these bodies and assess the validity of the internal conviction of officials of these bodies, monitor the correctness of their application of criminal and criminal procedure laws.

Otherwise, the court would invade the competence of the investigator, interrogator, prosecutor, limiting their procedural independence in the commission of procedural actions and decision-making and would prejudge issues that may later become the subject of legal proceedings.
On the functions of the prosecutor in criminal proceedings
Authors: Tabolina K. A.
Published: May 2024

The article is devoted to the study of the functions of the prosecutor in the judicial stages of criminal proceedings, and provides an analysis of statistical data from the General Prosecutor’s Office of the Russian Federation on the participation of prosecutors in criminal proceedings. The results obtained allow us to assert that the prosecutor performs two functions during criminal proceedings: the criminal procedural function of prosecution and the constitutional and legal function of supervision over compliance with the Constitution of the Russian Federation and the execution of laws. At the same time, at the stages of trial (in the court of first instance) and appeal proceedings, when the principle of adversarial parties is fully implemented, the prosecutor supports the state prosecution, thereby performing the procedural function of the prosecution. In the remaining stages of judicial proceedings, the prosecutor exercises the function of supervising compliance with the law. The conclusion is formulated that the proposed approach requires a rethinking of the role of the prosecutor in criminal proceedings from the position of the constitutional and legal status of the Russian prosecutor’s office, as well as amendments to the norms of criminal procedure law.
The importance of electronic evidence in criminal proceedings
Authors: Platonov V. V.
Published: May 2024

The development of digital technologies contributes to the change of criminal procedural relations and the emergence of electronic evidence used in the proof process. The author’s position is formulated based on the results of the analysis of theoretical approaches in criminal procedure science to the definition of the concept of “electronic evidence”. Arguments are presented confirming the need to use electronic evidence in criminal proceedings in order to overcome the risks associated with the realization of the rights and legitimate interests of participants in a criminal case, the preservation of evidence in case of their referral to the place of investigation, destruction or modification in case of counteraction to the investigation. The article reveals the importance of electronic evidence in criminal proceedings. Based on the analysis of the norms of criminal procedure legislation and law enforcement practice, the factors that determine the increasing importance of electronic evidence in criminal proceedings are substantiated.
