Experimental Research on Green Concrete
Authors: - Neda Rasoly , - Prof. Kongan Aryan
Published: July 2024

Concrete is a predominant material in global construction due to its versatility and essential role in various infrastructure projects. However, its production is responsible for approximately 8 to 10 % of global CO2 emissions, primarily attributed to the manufacturing of cement. Consequently, there is a critical need to reduce concrete usage and seek eco-friendly alternatives to conventional cement. Green concrete refers to concrete produced by incorporating waste materials such as fly ash, slag, by-products from power plants, recycled concrete aggregate, and waste glass, this approach aims to reduce carbon dioxide emissions associated with traditional concrete production.
This study presents experimental work conducted on both conventional and green concrete samples of M40 mix design. The green concrete samples incorporated fly ash as a partial replacement for cement at 20%, 25%, and 30% levels, and used recycled concrete aggregate (RCA) to replace 50% of both fine and coarse aggregates. The primary objectives were to design a concrete mix that maintains properties comparable to conventional concrete, reduces environmental impact by substituting waste materials for cement, and achieves cost efficiency.

Pada tulisan ini membahas tentang sebuah implementasi penggunaan mesin ATM dimana pada umumnya menggunakan jaringan VSAT namun saat ini sudah bisa dengan menggunakan dual WAN wireless GSM sebagai transmisinya. Seiring dengan berkembangnya IOT solusi ini tentu bisa memberikan kemudahan dari segi instalasi dan juga dapat dijadikan sebagai solusi dari segi keterjangkauan biaya. Dimana biasanya setiap perusahaan harus tetap menjalankan operasionalnya tanpa terhalang dengan budget yang ada. Metode yang digunakan dalam tulisaan ini dengan metode lowest latency yang dapat membuat link komunikasi tetap berjalan lancar meskipun latencynya tinggi sebab metode ini hanya bisa melanjutkan link yang memiliki latency tinggi di fail over ke link yang latencynya rendah.Implementasi ini menghasilkan kuat sinyal primary yang terukur -74 dBm dan hasil kuat sinyal link secondary yang terukur -88 dBm. Hasil kuat sinyal dari keduanya dikatakan bagus karena sesuai dengan standard parameternya yaitu >-90 dBm. Dari hasil kuat sinyal tersebut dapat membuktikan jika mesin ATM yang menggunakan transmisi jaringan wireless GSM juga dapat beroperasi dengan baik. Baik tidaknya suatu mesin ATM juga dapat berdasarkan pada hasil download yang dihasilkan, yaitu pada link primary yang didapat terukur 3.97 Mbps dan hasil download pada link secondary terukur 7.41 Mbps. Hasil download dari kedua link tersebut merupakan hasil yang bagus karena bandwidth yang diatur pada mesin ATM ini adalah sebesar 2 Mbps, sehingga hasil dari kedua pengukuran download dari implementasi ini sudah sesuai dengan standard parameter yang ditentukan.Dengan menggunakan jaringan radio pada komunikasi ATM ini dapat dijadikan sebagai solusi alternative selain VSAT. Dimana perusahaan juga bisa lebih efisien terhadap biaya yang dikeluarkan.

Published: July 2024

Salah satu teknologi telekomunikasi selular yang sangat berkembang pesat saat ini adalah pengembangan system transport berbasis IP. Kendala yang terjadi pada system transport IP yaitu apabila link utama terputus, maka dibutuhkan back up link untuk dapat memindahkan trafik. Hal ini dilakukan untuk menjaga performansi interface IuPS agar dapat bekerja dengan baik dan tidak mengganggu layanan ke pengguna di daerah tersebut. Analisa dilakukan pada RNC suatu operator seluler di daerah layanan Luwuk. Awalnya, RNC Luwuk hanya menggunakan satu link untuk mengirimkan trafik ke router yang akan diteruskan ke core network. Untuk menghindari terganggunya layanan komunikasi, jika link utama tersebut mengalami gangguan atau terputus maka dilakukan pengaktifan back up link dan pengaktifan Bidirectional Forwarding Detection (BFD). Untuk mengetahui keberhasilan pengaktifan back up link dan BFD dilakukan pengamatan terhadap RNC Luwuk. Hasil pengamatan pertama pada test ping didapatkan hasil packet loss sebesar 0% (semua paket data yang dikirim dapat diterima), maximum delay dibawah 60%, dan maximum jitter dibawah 75%. Nilai trafik pada link utama yang awalnya mencapai 39,54 Mbps kini mulai stabil menjadi 11,45 Mbps setelah back up link diaktifkan.

Medical Safety, Security And Intelligence
Authors: Trifunović Darko
Published: July 2024

The COVID-19 pandemic was not only medical and health services, as their name suggests, have the task of informing their governments about all possible threats and risks that come from the internal or external arena. In order to be able to inform and for the state to be able to react readily, numerous conditions and preconditions must be met, which will be discussed in this article. By analyzing the content of educational institutions that deal with medical sciences, security science, or intelligence, numerous shortcomings in the education process itself can be easily identified, which certainly have their consequences in practical work as well. The intelligence services did not have a clear picture or knowledge about the possibility of threats such as in the case of COVID-19, because the pandemic itself and the number of victims are proof of that. In other words, experts in medical sciences did not have the opportunity to exchange their information and to educate experts from Security Science or Intelligence in a certain way so that they would recognize or detect a threat. In the same way, experts in medical sciences do not know nor are they educated to understand the intelligence cycle or knowledge in the field of Security Science or Safety.
Medical Intelligence And Public Health In The Complexities Of Contemporary Societies The Role Of FBI In The United States
Authors: Visali Antonella Colonna
Published: July 2024

The term Medical Intelligence (Medint) defines the activities of collection, evaluation, analysis and interpretation of medical, bio-scientific and environmental information, regarding a specific country or geographical area, carried out mainly by military or intelligence agencies and carried out abroad, and useful for military or humanitarian strategic planning. It is of interest to Medint to know the potential of local health facilities, both civil and military, in the diagnostic evaluation, in case of infectious pathologies and in the evaluation of environmental risks as well as the "state of the art" of the development of computerized diagnostic technology and of biotechnology. The SMI (Strategic Medical Intelligence) is instead institutionally delegated to the intelligence agencies that deal with territorial control (counter-terrorism). In the United States, the SMI bioterrorism experts depend on the FBI. According to the definition offered by the FBI, Strategic Medical Intelligence (SMI) deals with all the management activities of a medical or health crisis situation following a terrorist act.
Use Of Medical Tools In Gaining Vital Intelligence For National Security Purposes
Authors: Kanayam Rene
Published: July 2024

The definition of Medical Intelligence is by all accounts a broad and complex scientific task that needs to encompass wider ramifications of using medical and biological data to advance national security interests. The paper focuses on examples of using the medical discipline in the form of an exhaustive collection of medical data in order to arrive at very specific results significant in the pursuit of national security or political stability, albeit only from the point of view of a particular actor – the state. The three representative cases are illustrated to arrive at a fundamental understanding of how the medical data – intelligence – can be used if the medical environment is burdened by the imperative to further strategic state-devised objectives. In the organization of a fictitious inoculation campaign in rural Pakistan by the Central Intelligence Agency in 2011 to track down the whereabouts of Osama bin Ladin through mapping the DNA pattern of purported bin Ladin’s relatives, the state actor focused specifically on collection of human biological samples while deploying covert tactics – both disregarding the purported motive of the “health campaign” as well as executing the operation on the foreign soil. In another example, perceiving the potential uncontrolled population growth as a direct threat to both vital national interests, as well as the country’s public image, Uzbekistan, on the state level, has engaged in mass forced sterilization programs to curb the national birth rate. In a similar perception, the treatment of the rare disease of leprosy in Uzbekistan historically encompassed methods incompatible with medical ethics and basic human rights.The precedents will be examined as part of the wider discourse on what constitutes Medical Intelligence, and what is permissible within the framework of national security concerns.
Effective roles of exercise and diet adherence in non-alcoholic fatty liver disease
Authors: Zhu Wei
Published: July 2024

Non-alcoholic fatty liver disease (NAFLD) is characterized by symptoms of excessive fat accumulation and steatosis in the liver without alcohol intake in patients. The associated pathogenic mechanism is not completely understood and there are no specific drugs for patients with NAFLD. Exercise and diet adherence are the best options for the management of NAFLD patients. Questionnaire associated analysis models of adherence to these interventions are used to assess their effectiveness in the management of NAFLD patients using specificity, sensitivity, and so on. Studies have indicated that the relative ratio of NAFLD can be reduced by physical activity with diet control. In the future, the pathogenesis of NAFLD should be clarified with stratified efforts to develop appropriate drugs, and both exercise and diet adherence should be optimized using better questionnaire design and evaluation models for patients with NAFLD.

Published: July 2024

BACKGROUND

Early diagnosis is key to prevent bowel damage in inflammatory bowel disease (IBD). Risk factor analyses linked with delayed diagnosis in European IBD patients are scarce and no data in German IBD patients exists.

AIM

To identify risk factors leading to prolonged diagnostic time in a German IBD cohort.

METHODS

Between 2012 and 2022, 430 IBD patients from four Berlin hospitals were enrolled in a prospective study and asked to complete a 16-item questionnaire to determine features of the path leading to IBD diagnosis. Total diagnostic time was defined as the time from symptom onset to consulting a physician (patient waiting time) and from first consultation to IBD diagnosis (physician diagnostic time). Univariate and multivariate analyses were performed to identify risk factors for each time period.

RESULTS

The total diagnostic time was significantly longer in Crohn’s disease (CD) compared to ulcerative colitis (UC) patients (12.0 vs 4.0 mo; P < 0.001), mainly due to increased physician diagnostic time (5.5 vs 1.0 mo; P < 0.001). In a multivariate analysis, the predominant symptoms diarrhea (P = 0.012) and skin lesions (P = 0.028) as well as performed gastroscopy (P = 0.042) were associated with longer physician diagnostic time in CD patients. In UC, fever was correlated (P = 0.020) with shorter physician diagnostic time, while fatigue (P = 0.011) and positive family history (P = 0.046) were correlated with longer physician diagnostic time.

CONCLUSION

We demonstrated that CD patients compared to UC are at risk of long diagnostic delay. Future efforts should focus on shortening the diagnostic delay for a better outcome in these patients.

Published: July 2024

BACKGROUND

Calculus bovis (CB), used in traditional Chinese medicine, exhibits anti-tumor effects in various cancer models. It also constitutes an integral component of a compound formulation known as Pien Tze Huang, which is indicated for the treatment of liver cancer. However, its impact on the liver cancer tumor microenvironment, particularly on tumor-associated macrophages (TAMs), is not well understood.

AIM

To elucidate the anti-liver cancer effect of CB by inhibiting M2-TAM polarization via Wnt/β-catenin pathway modulation.

METHODS

This study identified the active components of CB using UPLC-Q-TOF-MS, evaluated its anti-neoplastic effects in a nude mouse model, and elucidated the underlying mechanisms via network pharmacology, transcriptomics, and molecular docking. In vitro assays were used to investigate the effects of CB-containing serum on HepG2 cells and M2-TAMs, and Wnt pathway modulation was validated by real-time reverse transcriptase-polymerase chain reaction and Western blot analysis.

RESULTS

This study identified 22 active components in CB, 11 of which were detected in the bloodstream. Preclinical investigations have demonstrated the ability of CB to effectively inhibit liver tumor growth. An integrated approach employing network pharmacology, transcriptomics, and molecular docking implicated the Wnt signaling pathway as a target of the antineoplastic activity of CB by suppressing M2-TAM polarization. In vitro and in vivo experiments further confirmed that CB significantly hinders M2-TAM polarization and suppresses Wnt/β-catenin pathway activation. The inhibitory effect of CB on M2-TAMs was reversed when treated with the Wnt agonist SKL2001, confirming its pathway specificity.

CONCLUSION

This study demonstrated that CB mediates inhibition of M2-TAM polarization through the Wnt/β-catenin pathway, contributing to the suppression of liver cancer growth.

Representation in administrative proceedings: analysis of legislation and judicial practice
Authors: Tsvirkun Yuriy
Published: July 2024

The article analyzes the procedural norms of law that regulate the issue of representation in the administrative proceedings of Ukraine. Based on the analysis, it was concluded that the institution of representation in the administrative process has undergone significant changes in connection with the judicial reform. During the administration of justice, courts of administrative jurisdiction decide the issue of participation in the case of a representative in the presence of conflicting legislation, which, in turn, creates ambiguity in judicial practice. Attention was drawn to the fact that the Code of administrative proceedings of Ukraine, in the new version, classified the bodies and persons who have the right to apply to the court in the interests of other persons to the participants of the case. In turn, from «persons participating in the case», «representatives» are included in a separate category of participants in the legal process, which is established in the norms of a special paragraph of the Code. A new term «self-representation» was also introduced, which is inconsistent with the norms of the Constitution of Ukraine. At the same time, self-representation distinguishes representation under the law in the presence of family relations and representation under a contract, which can be carried out by a lawyer or a natural person who has administrative procedural capacity, in cases of minor complexity and in other separate cases defined by law.

It is emphasized that the procedural law does not clearly demarcate the powers in the judicial process of bodies and persons who are granted the right to appeal to the court in the interests of other persons, and legal representatives. At the same time, both of them participate in the legal process based on the prescription of the law, and the purpose of their participation is completely the same.

At the same time, it is stated that self-representation is a new type of representation, which is different from representation under a contract or law in the generally accepted sense and which needs to be refined at the legislative level. It was noted that legislative changes in the institution of self-representation essentially helped to bypass the norms of the Constitution on exclusive representation by lawyers of individuals and subjects of power in court.

As a result, it was concluded that the legal regulation of the participation of the representative, including the self-representative, in the administrative process requires further scientific analysis and legislative improvement.

Key words:administrative court, participants in the legal process, representative, self-representative, norms of procedural law.
Warisan Mafqud dan Orang Mati Bersama Menurut Imam Mazhab dan Hukum Islam di Indonesia
Authors: Sarah  , Syamsul  , Abdul Jafar
Published: July 2024

This study aims to examine the legal implications for inheritance rights for parties involved in cases of mafqud (missing persons) and individuals who die together according to Islamic law and the Compilation of Islamic Law (KHI) in Indonesia. The research employs a normative legal study method with an Islamic law approach. The findings indicate that Islamic law provides specific provisions for mafqud cases, considering an individual deceased after a certain period, while in cases of individuals dying together, inheritance distribution is based on confirmation of the order of death. KHI follows a similar principle and involves religious courts in resolving inheritance disputes to ensure fairness. The discussion emphasizes the importance of consistent application of legal provisions and the crucial role of religious courts in addressing uncertainty and conflicts in inheritance distribution.
Automatic imitation is modulated by stimulus clarity but not by animacy
Authors: Wilt Hannah , Wu Yuchunzi , Trotter Antony , Adank Patti
Published: July 2024

Observing actions evokes an automatic imitative response that activates mechanisms required to execute these actions. Automatic imitation is measured using the Stimulus Response Compatibility (SRC) task, which presents participants with compatible and incompatible prompt-distractor pairs. Automatic imitation, or the compatibility effect, is the difference in response times (RTs) between incompatible and compatible trials. Past results suggest that an action’s animacy affects automatic imitation: human-produced actions evoke larger effects than computer-generated actions. However, it appears that animacy effects occur mostly when non-human stimuli are less complex or less clear. Theoretical accounts make conflicting predictions regarding both stimulus manipulations. We conducted two SRC experiments that presented participants with an animacy manipulation (human and computer-generated stimuli, Experiment 1) and a clarity manipulation (stimuli with varying visual clarity using Gaussian blurring, Experiments 1 and 2) to tease apart effect of these manipulations. Participants in Experiment 1 responded slower for incompatible than for compatible trials, showing a compatibility effect. Experiment 1 found a null effect of animacy, but stimuli with lower visual clarity evoked smaller compatibility effects. Experiment 2 modulated clarity in five steps and reports decreasing compatibility effects for stimuli with lower clarity. Clarity, but not animacy, therefore affected automatic imitation, and theoretical implications and future directions are considered.
PEDAGOGICAL AND CURRICULUM ISSUES IN TEACHING CHILDREN WITH SPECIAL NEEDS IN REGULAR CLASSROOMS: CLASSROOM PRACTICES, MANAGEMENT AND ASSESSMENT
Authors: NZOKA FRANCIS KATUMO
Published: July 2024

The implementation of inclusive education has gained importance as a means of enhancing the quality and accessibility of education for children with special educational needs (SEN). These children frequently face social and physical barriers that impede their ability to enter the workforce and receive an education, which can be detrimental to the social and economic advancement of a nation. There exists various pedagogical approaches to guarantee education for children with special educational needs. However, the inclusive approach sets itself apart from the rest by advocating for equal participation of SEN students in mainstream schools, where they sit in the same classes with their other, and non-SEN counterparts. The inclusive approach states that so as to lessen or completely remove the social, academic, and physical barriers that SEN student’s encounter in ordinary classrooms, governments and educational institutions must offer the necessary resources, both human and material. In order to improve the human capital acquisition of students with special education needs, inclusive education strives for social cohesiveness and a less biased educational approach. The assumption that children with special needs are as fundamentally competent as students without impairments underpins both the classroom and the school system. Therefore, instruction is provided to students in the least restrictive setting possible. For all learners, general education is the top choice for placement, meaning that they are as much as possible alongside their peers who do not have disabilities. Respecting, recognizing, and addressing the diversity and individuality of students is the cornerstone of effective inclusive education. The needs of every student must therefore be taken into account by education systems.
