Published: August 2024

Trong nghiên cứu này, cấu trúc armchair graphene đơn lớp nanoribbons (AGNRs) dưới ảnh hưởng của khuyết và tái cấu trúc tạo thành vòng 5-9 được đưa vào tính toán. Phương pháp gần đúng liên kết mạnh (TB) được sử dụng để khảo sát cấu trúc vùng năng lượng của vật liệu khi không có và có sự xuất hiện của điện trường ngoài. Bên cạnh đó, bài toán nhiệt điện cũng được thực hiện dựa trên phương pháp luận hàm Green. Kết quả khảo sát với M = 15 cho thấy rằng, độ rộng vùng cấm của vật liệu được chia thành hai vùng cấm con nằm quanh mức Fermi. Tùy thuộc vào các vị trí khuyết khác nhau, độ rộng vùng cấm sẽ thay đổi. Đặc biệt, dưới tác động của điện trường song song, độ rộng vùng cấm của vật liệu được điều khiển, dẫn đến sự thay đổi mật độ trạng thái (DOS) và hệ số Seebeck S của vật liệu. Như vậy, sự kết hợp của khuyết và điện trường ngoài mang nhiều tiềm năng để đưa vật liệu graphene hướng đến những ứng dụng trong tương lai.

Published: August 2024

The aim of this research was to map and classify some soils of coastal plain sands origin in Edo State, Nigeria. The study covered two areas, including Site A (4 hectares) and Site B (12 hectares). The methodology used was a systematic soil survey using a rigid grid at detailed scales (1:5000 for Site A and 1:10,000 for Site B), with two mapping units delineated at each site. A representative pedon was excavated in each mapping unit, described, and sampled for analysis. Soil samples were analyzed using standard laboratory methods, and the data were processed with descriptive statistics. Soil classification followed USDA soil taxonomy, the World Reference Base for Soil Resources, and local systems. The morphological properties showed reddish soil colors when moist, with structures varying from single grain crumb to sub-angular blocky, and textures from sand to sandy clay loam. The content of sand, silt, and clay ranged from ≥742.0 to ≤886.00 g/kg, from ≥15.00 to ≤26.00 g/kg, and from ≥88.00 to ≤190.00 g/kg, respectively. Meanwhile, pH, organic carbon, cation exchange capacity, and base saturation ranged from ≥5.24 to ≤5.58, from ≥4.80 to ≤13.70, from ≥6.71 to ≤11.90 cmol/kg, and from ≥9.80 to ≤21.60 cmol/kg, consecutively. Pedons 2A and 2B were classified as Rhodic kandiudults by USDA, Rhodic Nudiargic Acrisols (Arenic, Vetic) by WRB, and locally as the Orlu series. Pedon 1A was classified as Typic Udipsamments by USDA, Eutric Rhodic Arenosols (Transportic) by WRB, and locally as the Ahiara series. Pedon 1B was classified as Typic Eutrudepts by USDA, Eutric Rhodic Cambisols (Arenic, Ochric) by WRB, and locally as the Kulfo series.

Published: August 2024

Noni fruit (M. citrifolia L.) is a medicinal plant known for its antioxidant bioactive compounds, which have potential use as radiation protection agents. Despite their traditional use, the specific bioactive compounds and their efficacy as radiation protectants have not been thoroughly investigated. This study aims to address this research gap by evaluating the potential of noni fruit extract as a candidate for radiation protection using in-silico methods. Databases consulted include PubChem, PASS Online, and ProTox-II. The results identified nine bioactive compounds in noni fruit extract: quercetin, kaempferol, morindin, morindone, alizarin, nicotinamide, beta-sitosterol, squalene, and n-hexadecanoic acid. Among these, kaempferol, squalene, and n-hexadecanoic acid were found to be the most potent antioxidants. Kaempferol exhibited a low toxicity level (grade 5) with significant activity as an antioxidant (Pa ≥ 0.7), free radical scavenger (Pa ≥ 0.7), and radioprotector (Pa 0.3 – 0.7). Squalene, a triterpene with low toxicity (class 5), showed antioxidant activity (Pa 0.3 – 0.7), free radical scavenger activity (Pa 0.3 – 0.7), and radioprotection (Pa 0.3 – 0.7). n-Hexadecanoic acid, a metabolite with moderate toxicity (class 4), demonstrated lower antioxidant activity (Pa ≤ 0.3), while morindin exhibited free radical scavenging and radioprotective properties. The findings suggest that kaempferol, squalene, and n-hexadecanoic acid in noni fruit extract hold promise as candidates for radiation protection, as evidenced by in-silico analysis.

Penafsiran Restriktif Dan Pembuktian Unsur Digunakan Dalam Gugatan Penghapusan Merek
Authors: Bebeto Ardyo  , Peter Jeremiah Setiawan
Published: August 2024

Penulisan artikel ini bertujuan mengusulkan pendekatan baru terhadap penafsiran dan pembuktian unsur â€œdigunakanâ€ yang dapat digunakan pengadilan niaga terkait gugatan penghapusan hak atas merek. Problematika penulisan beranjak pada beragamnya putusan Pengadilan Niaga Indonesia yang menerapkan interpretasi dan standar pembuktian untuk memenuhi unsur â€œdigunakanâ€ tersebut. Artikel ini menerapkan metode komparasi ketentuan-ketentuan hukum dari Amerika Serikat dan Uni Eropa sebagai yurisdiksi dengan pengaturan lebih komprehensif terkait penghapusan hak atas merek. Analisis problematika terhadap putusan-putusan Pengadilan Niaga Indonesia dan komparasi ketentuan beberapa yurisdiksi menghasilkan temuan bahwa penafsiran restriktif yang seharusnya mempersempit unsur â€œdigunakanâ€ dalam gugatan penghapusan merek sebagai penggunaan yang sesungguhnya terhadap merek, termasuk namun tidak terbatas pada penggunaan dalam perdagangan (genuine use in commerce) yang dilandasi dengan prinsip bona fide use. Merek tersebut ditafsirkan masih digunakan apabila barang dan/atau jasa terkait merek tersebut secara aktual benar-benar masih diproduksi, diperdagangkan secara nyata, dan ditambah dengan itikad baik dari pemilik merek atau produsen untuk mempromosikan atau mengusahakan mereknya dalam rangka mempertahankan hak atas merek yang dimiliki. Guna membuktikan penafsiran tersebut para pihak yang bersengketa seharusnya dapat membuktikan gugatan maupun bantahannya berdasarkan bukti keterangan dari lembaga jasa survei independen terkait dengan perdagangan.

Authors: Nurul Insi Syahruddin  , Topo Santoso  , Desi Fitriyani  , Winda Sari
Published: August 2024

Tulisan ini dilatarbelakangi oleh adanya pro kontra terkait penerapan konsep keadilan restoratif dalam penegakan hukum kasus investasi ilegal di Indonesia. Pada tulisan ini akan mengkaji pengaturan dan upaya aparat penegak hukum serta penerapan restorative justice dalam penegakan hukum kasus investasi ilegal di Indonesia. Metode yang digunakan adalah penelitian hukum normatif. Regulasi berkaitan dengan investasi ilegal diatur pada Undang-Undang Nomor 10 Tahun 1998, Undang-Undang Nomor 25 Tahun 2007, dan Keputusan Anggota Dewan Komisioner OJK Nomor KEP-72/D.04/2021. Lembaga yang berwenang di sektor keuangan dalam hal ini OJK melalui SWI tidak memiliki kewenangan untuk menindaklanjuti kasus investasi ilegal selain dari pemblokiran terhadap situs/website/aplikasi sehingga hanya menyampaikan laporan informasi ke Bareskrim Polri. Sementara itu, Keadilan Restoratif dapat diterapkan dalam penegakan hukum kasus investasi ilegal di Indonesia dengan mempertimbangkan instrumen hukum yang berlaku, tujuan, dan kendala terkait. Namun, penerapannya harus memperoleh persetujuan dari korban. Penerapan keadilan restoratif dalam penegakan hukum kasus investasi ilegal memerlukan upaya optimal dalam penelusuran pelaku, baik pelaku utama maupun pelaku lain yang terlibat, melalui koordinasi antara Satgas Waspada Investasi dan Badan Cyber Nasional untuk mencegah pihak-pihak lain yang kembali membuka penawaran investasi ilegal. Apabila berlanjut pada tahap ajudikasi atau penuntutan, restitusi dapat dilakukan dengan melibatkan Lembaga Perlindungan Saksi dan Korban.

Objective: This study was conducted to assess the risk of contrast-induced AKI (CI-AKI), among Saudi patients who underwent enhanced CT scans at a tertiary care hospital; to understand the incidence and the underlying associated factors of CI-AKI.
Methods: We conducted a retrospective review of patients who underwent CT scans with IV contrast from 2016 to 2021, at the King Abdulaziz University Hospital, Jeddah, Saudi Arabia. All authors had no access to information that could identify individual participants during or after data collection. The occurrence of AKI was defined using the “Kidney Disease: Improving Global Outcomes” (KDIGO) consensus definition. The exclusion criteria comprised age <18 years and records with missing key clinical information. Statistical Package for the Social Sciences (SPSS) software, version 21 was used for statistical analysis. The prevalence is presented as a percentage with a 95% confidence level. A P-value <0.05 was considered statistically significant.
Results: We reviewed 2000 patient files, of which 1430 met the inclusion criteria. According to the KDIGO definition of AKI, the overall incidence CI-AKI in our study cohort was 8.7%. The incidence of CI-AKI varied across baseline CKD stages, with significantly higher occurrences observed in individuals with CKD Stage5 at 24.3% and Stage4 at 15.9%. Statistical analysis confirmed that the likelihood of CI-AKI is significantly influenced by the baseline eGFR levels. This retrospective analysis found that individuals with hypertension have significantly higher odds of CI-AKI (OR = 2.02, p=0.001) compared to those without hypertension. Moreover, individuals with hyperuricemia have significantly higher odds of CI-AKI (OR = 2.78, p<0.001), compared to those without. The association remains significant after adjusting for other variables (OR = 2.40, p<0.001). The presence of diabetes, malignancy, anaemia, and ischemic heart disease did not show a significant association with CI-AKI.
Conclusions: Based on the results of this retrospective study, the overall incidence of CI-AKI is around 8.7 %, among patients undergoing enhanced CT scan. The risk is low and highly influenced by patients’ baseline kidney function.  Hypertension and Hyperuricemia are risk factors found to be associated with CI-AKI after enhanced CT scan. Diagnostic and clinically relevant enhanced CT scans should not be deferred based on the potential risk of CI-AKI. Furthermore, pre and peri-scan prevention protocols can significantly mitigate the risk of CI-AKI, even among high-risk patients.
Soft Tissue Sarcomas: Epidemiologic Trends at King Abdulaziz University Hospital in Jeddah
Authors: Refai Fahd
Published: August 2024

Objectives:
We aim to enhance the understanding of soft tissue sarcomas (STS) within the Saudi population, guiding better diagnosis, treatment strategies, and healthcare resource allocation for this rare but challenging cancer type.
 
Methods:
Retrospective data of 160 patients at King Abdulaziz University Hospital (2013-2023) were examined for demographics, anatomical sites, and diagnoses of STS. Statistical analysis in RStudio (R v4.3.1) utilized Fisher's exact and chi-squared tests for categorical variables (p<0.05), while continuous variables were summarized by medians and interquartile range.
 
Results:
We included patients with STS, evenly split between males and females (median age: 47 years) Significant differences were observed between age groups: younger patients (<50 years) more commonly had rhabdomyosarcoma and synovial sarcoma, while older patients (≥50 years) showed higher rates of dedifferentiated liposarcoma, Kaposi sarcoma, and leiomyosarcoma. Sarcoma locations varied, with the thigh, retroperitoneum, and head and neck being prominent sites. Higher frequencies of Kaposi sarcoma and skin sarcomas were noted in males, and leiomyosarcoma and uterine sarcomas exclusively in females.
 
Conclusion:
The study highlights significant sex and age disparities in the diagnosis and distribution of STS among Saudi patients. Rhabdomyosarcoma emerges as the most frequent subtype, influenced by factors such as genetic predisposition and advanced diagnostic capabilities. Understanding these demographic variations is crucial for developing targeted treatment strategies tailored to the unique needs of different patient groups. Further research into the underlying biological and environmental factors driving these disparities is essential for advancing sarcoma care and improving patient outcomes in Saudi Arabia.

Published: August 2024

Objective: To determine the prevalence and significant correlates of prediabetes (pre-DM), diabetes mellitus (DM), prehypertension (pre-HT), and hypertension (HT) among adults in all districts of Duhok Governorate through a community-based screening study.
Methods: This is a cross-sectional community-based screening study involving 3,000 non-fasting adults not diagnosed as prediabetes or DM and prehypertension or HT conducted in all districts of Duhok Governorate. Random glucose and blood pressure reading according to American Diabetes Association and American Heart Association Guidelines in 2023 will be used in a community-based screening. BMI will be also calculated in the present study as a screening tool.
Results: Findings reveal that 18.2% had DM, 14.7% had pre-DM and 41.3% had HT and 11.5% had pre-HT. The study also revealed that nearly two third had increased BMI in which 40.1% were overweight and 24.5% were obese. Among screened subjects 32% were smokers. Around half of screened subjects reported having family history of DM and HT, DM alone (10.8%), HT alone (12.1%) and 28.9% had family history of both DM and HT together. The study also shows that screened male subjects reported higher prevalence of pre-DM, DM, pre-HT and HT than screened female subjects. Older age group of screened subjects tend to have more abnormal blood sugar and blood pressure levels than younger age group.
Conclusion: This study has shown a high prevalence of pre-DM, DM, pre-HT and HT among adults in all districts of Duhok Governorate. Significant correlates of pre-DM, DM, pre-HT and HT in this study were age, gender, BMI, smoking and family history.
Enhanced Antibacterial Activity of Manuka Honey with Higher Methylglyoxal Concentration Against Staphylococcus Aureus: in vitro study
Authors: Halwani Muhammad
Published: August 2024

Objective
This study aimed to investigate the antibacterial activity of two types of Manuka honey with varying concentrations of methylglyoxal (MGO), 70 mg/kg and 1050 mg/kg, against S. aureus in vitro.
Methods
Two types of Manuka honey were tested for their antimicrobial activities. The Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were determined using the broth tube dilution method.
Results
Both concentrations of Manuka honey exhibited antibacterial activity against S. aureus, with the higher concentration (1050 mg/kg) showing enhanced antibacterial effects. The MIC was 100% v/v (undiluted) for the lower concentration and 50% v/v for the higher concentration. The MBC was inferred to be at a dilution of 50% v/v for the higher concentration, but not reached for the lower concentration at the dilution levels used.
Conclusion
The findings suggest that Manuka honey with a higher concentration of MGO may be more effective in inhibiting and potentially killing S. aureus. The study highlights the potential use of high-concentration Manuka honey as an alternative antimicrobial agent and calls for further investigation in clinical settings.

Authors: Shatskaya I. V.
Published: August 2024

The unprecedented sanctions policy against Russia forces us to think about the directions of development of the domestic economy. One of the priority directions is the development of the domestic electronic industry — the most knowledge-intensive branch of mechanical engineering, the structural core of the post-industrial wave in accordance with the wave concept of E. Toffler. It is electronic products, including components and products made from them, that are extremely differentiated and, among other things, serve as components for other industrial and consumer goods. This means that the development of other spheres and sectors of the economy becomes difficult without the development of the electronic industry. To determine the basic strategy for the development of the electronic industry in Russia. Tasks of the article — to identify the strategic role of innovations in electronics and microelectronics in Russia’s achievement of technological sovereignty.

The article is based on the general theory of strategy and methodology of strategizing by academician, foreign member of the Russian Academy of Sciences V. L. Kvint, developed at the Center for Strategic Studies of the Institute for Mathematical Research of Complex Systems and the Department of Economic and Financial Strategy of Lomonosov Moscow State University.

The article provides an overview of global innovation trends and startups that are transforming the electronic industry today. In addition to the review, the author provides statistical information on the level of development of these technologies in Russia.

Published: August 2024

The purpose of the work is to assess the role of digital technologies as a strategic factor in regional development from the point of view of the theory of strategy and strategizing methodology of academician V. L. Kvint. The problems of formation, development and measurement of processes associated with the digital economy are described. The analysis is based on the concept of three levels of development of the digital economy and digital inequality of regions. Analysis of static data for the regions of the Russian Federation on indicators characterizing the level of Internet accessibility and use of digital technologies, the results of calculations using various multifactor methods allowed the authors to substantiate the need to create a comprehensive methodology for assessing the level of penetration of digital technologies into the regional economy for strategizing purposes. Understanding the mechanisms for the transition of the availability of digital technologies into economic indicators of regional growth will make it possible to use the opportunities of digitalization to ensure competitiveness at the regional, national, and global level. It is necessary to form a holistic view of the region as a subject of strategizing economic development, which will correspond to the basic principles of creating and developing the digital economy.
The Role of Russia in Maintaining Global Equilibrium: Historical Facts and Modern Realities
Authors: Poltavchenko G. S.
Published: August 2024

The purpose of the article is to study the historical place and role of Russia in the modern structure of the world.

21st century had begun with the well-established opinion that after the collapse of the USSR, the hegemony of the collective West came. Western ideologists began to aggressively impose their vision of the world order on the entire planet, intoxicated by the victory in the Cold War, Washington and its satellites are particularly furious at Russia’s position. The country, which is the legal successor of the Soviet Union, which lost the Cold War, allows itself to pursue an independent policy that runs counter to the interests of the “winners”.

The collective West has unleashed a full-scale hybrid war against the Russian Federation. All this is being done, on the one hand, to contain Russia, weaken it and oust it from the world political arena, up to the dismemberment or complete destruction. On the other hand, as a warning to those states that do not want to join the globalist plans of the United States. Thus, today’s confrontation between the Russian Federation and the collective West should be considered not only, and not so much as a struggle for economic interests, but as a global confrontation between neoliberalism, the unnatural ideas and “values” imposed by it, and the traditional way of life, proven by thousands years of history, on which most sovereign nations are based.
Uma espada de dois gumes: abordagens conceituais da participação no movimento antidemocrático após as eleições presidenciais brasileiras de 2022
Authors: Evangelista Raquel , Quaresma Flaviano
Published: August 2024

Este artigo propõe uma reflexão teórica sobre os limites do conceito de participação e sua eventual instrumentalização política em um ambiente democrático. Os pensamentos de Arsntein (1969); Carpentier (2011); Sharp (2017) e Melo et al. (2019) compõem a base da revisão bibliográfica. Além dela, foi elaborado um estudo de caso descritivo, cujo objeto de estudo é a participação das pessoas no Twitter nas ações de denúncia da tentativa de golpe no dia 08 de janeiro em Brasília. Enquanto os resultados da revisão bibliográfica apontam que a variedade de conjunturas históricas, sociais e políticas é um obstáculo para uma compreensão única da participação e sua relação com a mídia; o estudo de caso dá pistas de que a participação dos cidadãos brasileiros pelo Twitter é complexa, apresentando traços de interação, partilha de poder e participação negativa.
