The rise of fake news in today's age of mass media poses a serious threat to the credibility of the media and public discourse [1]. This project focuses on developing effective and robust solutions to detect fake news by integrating multiple machine learning algorithms. This project uses a variety of techniques, including natural language processing (NLP), clustering, classification algorithms and deep learning, to identify the content of patterns that indicate error messages. The project first explores NLP algorithms to extract content from news media content. These features allow the system to understand and classify the language used, helping to identify language patterns associated with fake news. Additionally, emotional analysis plays an important role in visualizing the tone and content of the text, further increasing the accuracy of the findings. The integration method is used to combine various machine learning models. By combining the performance of various algorithms, the system aims to overcome individual limitations and provide a more comprehensive and effective evaluation of media content. This approach helps increase the power of fake news detection and adapts to different fraud strategies. The project also includes deep learning algorithms, especially neural networks, to capture relationships in data. The use of deep learning ensures that the system can recognize nuances in the language and clarifies the complex information of the error message. Continuous updating and reworking of machine learning models is an important part of the process, allowing the system to constantly adapt to fraud strategies [2]. The aim of fake news detection system is to create a well-informed, weak search for fake news that can help create greater awareness and public approval.

Driving is a complex activity performed in a continually varying and stimulating environment. The coordination and execution of various skills like cognitive, sensory, psychomotor and physical are extremely necessary to drive safe. Most of the studies related to driving highlighted that 75% of traffic accidents occurs due to human factors including driver’s fatigue, deprived health condition, attention loss, bad emotional state, and lack of skills. Most of the developed country is ageing. Hence, the drivers above 60 years is also increasing. Ageing results are weakening in cognitive function and threaten driver safety. The aged drivers (age above 60 years) have a comparatively more significant risk of accident due to medical emergency than other factors like bad emotional state and lack of skills. The wellness of drivers’ is considered as a key factor of traffic accidents. Heart failure and non-traumatic disease (i.e., stroke) are the main risk factors for drivers’ death. Many of the victims have no prior knowledge of the presence of the condition. Stroke is a disease caused due to the disturbance in blood supply to the parts of the brain. After experiencing stroke, a driver’s ability to drive is generally affected by the visual, perceptual, motor, and cognitive deficits. Stroke leads to arm weakness, facing dropping, blurred vision, dizziness, coordination issue and speech difficulties of victims which are essential for driving.

Authors:   Department of Medical Microbiology & Immunology, Faculty of Medicine, Aswan University, Aswan, Egypt., Nageeb Heba
Published: April 2024

T helper 17 (Th17) cells have been reported to be the most powerful factor in autoimmune disorder pathogenesis, which points to the Th17 master cytokine, interleukin (IL)-17A, as the crucial mediator. We aimed to determine the impact of IL-17A polymorphism in the -197 G/A promoter region on level of IL-17 and intensity of rheumatoid arthritis (RA) disease symptoms. This case-control study was conducted at the Department of Clinical Rheumatology of Aswan university Hospital and included 35 people suffering RA and 30 volunteer controls, matched for age and sex. Rheumatoid factor (RF), anti-cyclic citrullinated peptide (anti-CCP) antibodies, erythrocyte sedimentation rate (ESR), serum IL-17, and C-reactive protein (CRP) were measured in the RA patient group. Restriction fragment length polymorphism (RFLP) was conducted by polymerase chain reaction (PCR) amplicon obtained by IL-17A -197 G /A primers. Of the 35 RA patients, RF was positive in 33 (94.29%) and anti-CCP antibodies in 25 (71.43%), CRP in 31 (88.57%). Of the 35 RA patients, 5 (14.29%) patients carried the G/G genotype, 18 (51.43%) G/A and 12 (34.29%) A/A. IL-17 serum level was significantly greater in the more active RA (DAS28 >5.1) group than the less active (DAS28 ≤5.1) group. Of the RA patients carrying wild type G/G genotype, 60% had more active disease (DAS 28> 5.1), as compared to those with lower activity (DAS 28 ≤5.1), 40% carried the wild type G/G genotype. In conclusion, the study findings imply that IL-17A gene polymorphism is connected to RA clinical severity rather than with RA susceptibility.

Authors:   Department of Medical Microbiology & Immunology, Faculty of Medicine, Zagazig University, Zagazig, Egypt., Nabil Fedaa
Published: April 2024

Hepatocellular carcinoma (HCC) is one of the most prevalent cancers in the world. Two risk factors that cause 80–90% of HCC cases globally are chronic infection with hepatitis B virus (HBV) and hepatitis C virus (HCV). The diagnostic value of circulating microRNAs (miRNAs) in numerous tumors has been described. Our research assessed microRNA-16 (miR-16) as a novel biomarker in patients with HCV-induced HCC. The study included three groups. Group 1 included 55 individuals with cirrhosis caused by liver HCV infection in addition to HCC. Group 2 included 55 individuals with cirrhosis brought on by HCV infection. Group 3 included 55 normal control individuals. Expression of miR-16 in blood was assessed by real-time polymerase chain reaction (RT-PCR). The mean level of miR-16 was significantly different in the three groups, with group 1 having the greatest value (1.098 ± 0.647), followed by group 2 (1.1035 ± 0.8567) and group 3 (control subjects) having the lowest value (0.3842 ± 0.21485). The receiver operating characteristic (ROC) curve analysis showed that miR-16 had a higher diagnostic value at area under the curve (AUC) of 0.935 than alpha-feto protein (AUC of 0.859) to differentiate between HCC and control subjects. MiR-16 has a sensitivity of 81.82 % and a specificity of 69.09%, to distinguish between patients with liver cirrhosis and HCC patients. Our findings illustrated that circulating miR-16 can be proposed as a marker for detection of patients with HCV-induced HCC.

Authors:   Department of Internal Medicine, Faculty of Medicine, El Manzala Central Hospital, Mansoura University, Mansoura, Egypt., Hendam Doaa
Published: April 2024

In the first phase of its treatment program, Egypt aimed to treat 250,000 people annually until 2020, thereby reducing the number of viremic patients and limiting hepatitis C virus (HCV) transmission. Egypt strives to eradicate HCV and HCV-associated morbidity by 2030. This study aimed to determine the prevalence of HCV infection among end-stage renal disease patients and the reasons for non-treatment among those offered free medication. This multi-center cross-sectional study was conducted during the period from November 2022 to April 2023. The study included 500 patients receiving hemodialysis (HD) sessions on a regular basis for more than three months in Dakahlia Governorate. According to patients` medical history, we found that 23.4% of patients had previous HCV infection. Of these, 12.6% received treatment, and 10.8% did not receive treatment due to a variety of reasons. For instance, some patients were unaware of the drug’s availability, five patients (1%) feared side effects, 43 patients (8.6%) did not require treatment, and five patients (1%) had other causes as contraindications of drugs, noncompliance and deterioration of health status. In addition, 20.4% of patients were reported to have fully recovered, while 0.8% had a recurrence. After investigations, 1% of patients had positive hepatitis B surface antigen (HbsAg), 23.4% positive HCV Ab, and 4.2% positive HCV by the polymerase chain reaction. In conclusion, the low prevalence of HCV among HD patients confirms that HCV infection is not currently a significant health concern among patients on maintenance HD.

Published: April 2024

The optimal layout of wind power plants is very important as the arrangement of wind turbine generators (WTGs) profoundly affects the overall energy output of the wind power plant.  To address this important issue, this research investigates the best layout for WTGs in wind power plants with different terrain features across three locations in Thailand using the Ant Colony Optimization (ACO) algorithm.  The objective functions of maximizing the net annual energy production (AEP) and minimizing the wake losses were used to achieve the optimal wind power plant layout.  Using the MERRA-2 database, computational fluid dynamics (CFD) wind flow modeling was performed to create 10x10 km2 microscale wind resource maps of locations characterized by flat, semi-complex, and complex terrains to install wind power plants.  The CFD wind flow modeling yielded wind speeds of 5.00 to 5.76, 4.21 to 8.90, and 3.10 to 4.45 m/s for the flat, semi-complex, and complex terrains, respectively, making them feasible for utility-scale wind power plants.  WTGs of multiple blade diameters, ranging from 90 to 126 m, with a nominal capacity of 2.5 MW at 100 m above ground-level hub heights, were used in this study.  The Gamesa G126-2.5MW WTG with a 126 m blade diameter produces the highest net AEP of 14.3, 76.1, and 38.9 GWh/yr for the three terrains.  Hence, this WTG was used to perform an ACO-based optimization to improve the electricity production of the wind power plants.  Such studies are important to improve the efficiency of wind power plants, thus extracting the maximum kinetic energy possible from the winds and improving the economic viability of wind power plants.

Published: April 2024

The use of rice husk ash functionalized with organic amine groups (RHA-NH2) as an adsorbent for acid dye adsorption from wastewater was studied. The RHA–NH2 was synthesized successfully via the grafting method using (3-Aminopropyl)-triethoxysilane (APTES) as amine group precursors. The synthesized adsorbents were characterized by using X-ray Powder Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), N2 adsorption-desorption analysis, and Scanning Electron Microscopy (SEM). The RHA-NH2 exhibited an amorphous silica structure and possessed the organic amine group functionalized on the silica surface. The adsorption was studied by using Acid Blue 225 as an acid dye. The amount of acid dye remaining in the aqueous solution was measured by ultraviolet-visible spectrophotometer (UV-Vis). The RHA-NH2 revealed a higher adsorption capacity (~82 mg/g) than RHA because the amine group enhanced the chemisorption energy.

Published: April 2024

This study investigated the rice income and expenses of lowland rain-fed farmers in Barangay Tubog to ascertain whether these farmers could generate profits. A survey questionnaire was utilized to collect the data. The findings indicated that rice farmers earned an average annual income of P11,571.43. Conversely, their agricultural costs amounted to an average of P15,681.68 per cropping season. The study revealed that farmers needed more awareness regarding the recommended fertilizer application rates for a given farm area. Consequently, they incurred higher expenses on inputs, which harmed their income. Specifically, the average total cost of land preparation was found to be P3,084.09. The labor cost averaged P3,050.00, while the total expenses on fertilizer per cropping season averaged P5,812.42. Furthermore, the average total cost of pesticides per cropping season was approximately P1,258.42, and the average total milling cost amounted to P1,756.75. Overall, the entire agricultural expenses averaged P15,681.68 per cropping season. In terms of household expenses, the average was calculated to be P12,626.47. The researchers discovered that lowland rain-fed rice farmers in Barangay Tubog incurred higher expenses while generating lower income due to limited production output. This is likely due to some factors, including outdated farming practices, lack of access to credit, and the high cost of inputs. These findings suggested a need for government intervention to support lowland rain-fed rice farmers in Barangay Tubog. This could include providing farmers access to improved farming technologies, credit, and market linkages.

Published: April 2024

Than đá đóng vai trò quan trọng trong sự phát triển của các ngành năng lượng trên thếgiới. Tuy nhiên, tro xỉ (các sản phẩm của quá trình đốt than) chứa phóng xạ, kim loạiđộc hại, thải ra từ các nhà máy nhiệt điện đang là mối lo ngại đối với môi trường. Trong nghiên cứu này, hệ phổ kế gamma HPGe được sử dụng để xác định hoạt độ phóng xạ trong các mẫu than, tro bay, xỉ và hệ số tăng cường trong một số nhà máy nhiệt điện than ở Việt Nam. Kết quả cho thấy hoạt độ phóng xạ trong các mẫu khá ngẫu nhiên. Trung bình hoạt độ phóng xạ trong mẫu giảm dần theo thứ tự: tro bay > xỉ > than. Có sự tăng cường hoạt độ phóng xạ tự nhiên trong các sản phẩm đốt than, hệ số tăng cường dao động từ 1,22 (xỉ/than) của 40K trong mẫu DH3 – Đ.1 đến 5,21 (tro/than) của 232Th trong mẫu VT 4 - Đ.1. Số liệu về phóng xạ cung cấp động lực để phát triển và thúc đẩy việc áp dụng công nghệ mới, tiên tiến hơn để giảm thiểu ô nhiễm và tác động đến môi trường từ nhà máy nhiệt điện.® 2024 Journal of Science and Technology - NTTU

Amikacin là kháng sinh thuộc nhóm aminoglycosid được sử dụng trong thực hành lâm sàng điều trị nhiễm khuẩn Gram (-) hiếu khí nặng đe dọa đến tính mạng người bệnh. Tuy nhiên, đây là kháng sinh phụ thuộc nồng độ và có khoảng trị liệu hẹp, độc tính cao nhất là độc tính trên thận và thính giác. Do đó, việc sử dụng amikacin hiệu quả và an toàn cần tuân thủ nghiêm ngặt về chỉ định, chế độ liều và phải được theo dõi hợp lí. Từ đó phát hiện sớm độc tính và điều chỉnh liều cho bệnh nhân. Khảo sát nồng độ amikacin trong máu của nhóm bệnh nhân độ tuổi trung bình (57,0 ± 15,3) tuổi, thời gian nằm viện (6,8 ± 2,4) ngày, với liều trung bình (13,6 ± 2,3) mg/kg/ngày cho kết quả nồng độ khoảng giữa (Cmid-level) ở thời điểm (9 - 12) giờ có 36,4 % bệnh nhân trong vùng 24 giờ, 59,1 % dưới ngưỡng phát hiện và 4,5 % trên vùng 24 giờ. Ở chế độ liều nhiều lần trên ngày (MDD) trong khoảng trị liệu, 87,5 % bệnh nhân có nồng độ đỉnh (Cpeak). Nồng độ đỉnh chế độ liều một lần trên ngày (ODD) chỉ có 9,1 % bệnh nhân đạt khoảng trị liệu. Nồng độ đáy (Ctrough) chế độ liều ODD bệnh nhân trên ngưỡng trị liệu là 23,1 %. Trong số 5 % bệnh nhân độc thận có 2,5 % suy thận cấp sau 3 ngày. Chưa phát hiện bất thường trên thính giác và tiền đình trong quá trình điều trị.

This technology works without any mortal intervention. It means that if there are many people and further no of places to cover also we can use this technology to cover the camera with utmost perfection.
QUANTITATIVE EVALUATION OF THE INFLUENCE OF INDIVIDUAL FACTORS ON THE RESULT INDICATORS CHARACTERIZING THE COMPETITIVENESS OF RA AGRICULTURE AND THE INTEGRAL INDICATOR OF THAT COMPETITIVENESS
Authors: Tspnetsyan Lusine
Published: April 2024

It is impossible to get a comprehensive understanding of the impact of the factors
determining the competitiveness of agriculture without a regression model and a
quantitative assessment of that impact using econometric calculations, which
allows to izolate the factors that have a greater or lesser impact. However, the
range of result and factor indicators that have a statistical relationship with the
competitiveness of the Republic's agriculture is not comprehensive (taking into
account that not all of them may have such a relationship), which limits the possibilities of quantitative assessment of the joint impact of all factors on the said
competitiveness. In this case, it is necessary to limit to the quantitative assessment of the impact of specific factors on individual characteristics of agricultural
competitiveness. Taking into account the special role of the state policy factor in
increasing the competitiveness of agriculture in terms of creating the necessary
conditions and a favorable environment, the article highlighted and revealed the
individual characteristics of the competitiveness of RA agriculture in the studied
period: the value of the gross production of agriculture, the index of the volume
of agricultural products, the productivity and commodity of agriculture, the statistical relationship between the level and the factor of budgetary allocations to
agriculture considered as the bearer of the above-mentioned policy as a result of
regression analysis.

Which from the basis of the contemporary technology of graphene and is progressing, therefor, research in this field is important and this research was carried out in a library method and its purpose is to investigate the electronic structure of single – layer graphene.
STUDYING STRATEGIES TO ENHANCE INTEREST IN TEXT FROM A LINGUISTIC PERSPECTIVE
Authors:   University of Kerbala, Presidency University/ Information Technology Center, Iraq, Abdul.Z Ali Abdulhamzah
Published: April 2024

This work will focus on text-based interest, which may be found in this article using a linguistics method. The principles of linguistics of emotions, which integrate the findings of language and psychology studies, provide the groundwork for this strategy. The paper delves into the linguistic methods of text-based interest analysis and how they relate to interest's function in interactive instructional discourse. One definition of active, emotion-evoking discourse is the communicative scenario in which an informative text piques the reader's curiosity. The speaker's goal in adopting interest-evoking rhetorical tactics—that is, strategies for generating texts to evoke the audience's attention—is to "evoke the recipient's interest" in this particular discourse. Applying techniques from communicative-functional linguistics, we may analyze these systems. First, we can pinpoint specific tactics with the use of these methods. The essay uses two such systems—text dialogization and contextualization—in Russian textbooks as an example. Second, to implement these tactics, the communicative-functional approaches show the most important ways of using language and producing finished content. We think these methods are what people mean when discussing the concretization of text content, developing text emotiveness, and forming text dialogicity.
The Other Side of Language, Literature, and Living: A Call to Hedge the Dying Art
Authors: Panda Sachidananda
Published: April 2024

A written document is no longer treated as a piece of literature; rather, readers' needs have surpassed the limits of traditional expectations, beyond the purview of common scrutiny. A piece of writing has become a stale reminder of the time spent; the recurrent images of everyday life and living, the bread and butter of the populace, their anguish and pain, the contours of traditional moorings, nuances and nemesis, rituals and rebuttals clubbed together have become the choice of the present time. The big question, therefore, is to bring in necessary modifications to our notions and approaches towards literature, without which it amounts to infidelity with the readership. The present paper aims to highlight how different elements of behavioural knowledge are intelligibly incorporated in the verses of Ghodanacha and how they influenced the life and living of Kaibartas/Keuts for ages as scriptures of inspiration, encouragement, and discipline. This will connect the art's history, evolution, and current state as it stands at the gateway to its own graveyard.

En el presente texto se estudia la visión política de Jawaharlal Nehru y el proyecto nacional delineado por Bhimrao Ramji Ambedkar en el contexto de la transición de India desde un estado colonial a una nación independiente. Su enfoque se centró en los ideales de inclusión, así como la promulgación de una constitución que reflejara los valores de una república democrática y libre. Ambos líderes abogaron por los derechos de las castas marginadas y la democratización del país, ya fuera, bajo la idea de desarrollo científico o la de inclusión social. En este artículo se examinarán y compararán los modelos de nación presentes en los dos líderes, evaluando su influencia en los principios políticos fundamentales de la Constitución india promulgada en 1950 y su vigencia en la política actual de India.
A defesa da democracia enquanto política constitucional: reflexões prospectivas dos atos de 08 de janeiro de 2023 para além do punitivismo estatal
Authors: Kelner Lenice , Azevedo Gabriel Antonio Reinert , Lima Rafael Hamilton Fernandes de
Published: April 2024

Este artigo aborda a defesa da democracia, enquanto política constitucional, notadamente a partir dos atos de 8 de janeiro 2023, os quais se deflagraram, em um momento de embates institucionais, além de proposições de ruptura do regime democrático. A partir da análise do conceito de política constitucional e do regramento de tipificação penal, objetivou-se caracterizar a salvaguarda da democracia como um bem jurídico a ser tutelado por todos os entes estatais e da própria sociedade. Por meio do método indutivo e com as técnicas da pesquisa bibliográfica e documental, concluiu- se pela visão holística e concorrente das instituições para a adoção de medidas voltadas ao reordenamento da harmonia institucional entre os Poderes da República e, por conseguinte, a ausência desta atuação conjunta significará o desencadeamento de iniciativas autoritárias e nocivas à soberania popular, sobretudo, materializada no pleito eleitoral.

As estruturas de concreto armado são sujeitas a um tempo de vida útil, e que frequentemente enfrentam manifestações patológicas resultantes de falhas de execução, fatores externos, e produtos de baixa qualidade. Infelizmente, processos de degradação surgem antes do tempo de vida útil previsto, acarretando implicações significativas em termos de sustentabilidade, aspectos financeiros, estética e segurança. Este estudo se propõe a explorar as técnicas de reforço e recuperação estrutural no reservatório apoiado - R1 que em vistorias foram identificadas trincas indicativas de corrosão em diversos pontos, destacando a avançada deterioração da laje de tampa, onde a perda substancial da seção do aço exigiu substituição. Além disso, implementou-se um sistema de reforço nas paredes do reservatório. É imperativo ressaltar que, embora eficazes, esses sistemas de reforço não eliminam a necessidade de inspeções periódicas para garantir a contínua integridade da estrutura. Essa pesquisa contribui para a compreensão das complexidades na gestão de estruturas de concreto armado, sublinhando a importância do controle de qualidade e de intervenções adequadas para assegurar a durabilidade, sustentabilidade e segurança dessas edificações.
