Corrosion behavior of HRB400 and HRB400M steel bars in concrete under DC interference

The influence of direct current interference on the corrosion behavior of HRB400 and HRB400M steel bars in simulated concrete solution was studied using methods such as weight loss experiment, electrochemical experiment, surface technology and product analysis. The research results showed that with the increase of DC interference voltage, the corrosion rates of HRB400 and HRB400M steel bars would increase. The corrosion resistance of HRB400M steel bars was better than HRB400 steel bars under the experimental conditions. In addition, direct current interference could cause damage to the corrosion product layer on the surface of HRB400 steel bars and HRB400M steel bars. And the corrosion form and corrosion product types of HRB400 and HRB400M steel bars would be affected by direct current interference. The main corrosion products of HRB400 steel bars included γ-FeOOH and Fe2O3 when it was not interfered by DC. When DC interference was applied, the main corrosion products included Fe3O4 and Fe2O3. The corrosion products on the surface of HRB400M steel bars were mainly Fe3O4 and Fe2O3, and the types of products increased to form Cr2O3 and MnFe2O4.

Data analytics in education: are schools on the long and winding road?

Purpose This study aims to investigate the organisational structure to exploit data analytics in the educational sector. The paper proposes three different organisational configurations, which describe the connections among educational actors in a national system. The ultimate goal is to provide insights about alternative organisational settings for the adoption of data analytics in education. Design/methodology/approach The paper is based on a participant observation approach applied in the Italian educational system. The study is based on four research projects that involved teachers, school principals and governmental organisations over the period 2017–2020. Findings As a result, the centralised, the decentralised and the network-based configurations are presented and discussed according to three organisational dimensions of analysis (organisational layers, roles and data management). The network-based configuration suggests the presence of a network educational data scientist that may represent a concrete solution to foster more efficient and effective use of educational data analytics. Originality/value The value of this study relies on its systemic approach to educational data analytics from an organisational perspective, which unfolds the roles of schools and central administration. The analysis of the alternative organisational configuration allows moving a step forward towards a structured, effective and efficient system for the use of data in the educational sector.

Machine-Based Transliterate of Ottoman to Latin-Based Script

In this paper, a machine-based transliterate is presented. The automatic transliteration of Ottoman to the modern Latin Turkish script can open a big window for scientists in fields of history and literature while most of the Turkish people are not familiar with Ottoman script, despite the fact that no concrete solution has been proposed yet for this issue. The proposed method includes several steps since the transliteration process of Ottoman alphabet to Latin base consists of many problems; the first is the basic character mapping which covers the regular pronunciation and orthography mapping. On the other hand, covering other irregular and extraordinary cases is based on rules and normalization. The transliteration system achieved 73.9% accuracy in general.

Bone Biopsy for Histomorphometry in Chronic Kidney Disease (CKD): State-of-the-Art and New Perspectives

The use of bone biopsy for histomorphometric analysis is a quantitative histological examination aimed at obtaining quantitative information on bone remodeling, structure and microarchitecture. The labeling with tetracycline before the procedure also allows for a dynamic analysis of the osteoblastic activity and mineralization process. In the nephrological setting, bone biopsy is indicated to confirm the diagnosis of subclinical or focal osteomalacia and to characterize the different forms of renal osteodystrophy (ROD). Even if bone biopsy is the gold standard for the diagnosis and specific classification of ROD, the use of this approach is very limited. The main reasons for this are the lack of widespread expertise in performing or interpreting bone biopsy results and the cost, invasiveness and potential pain associated with the procedure. In this regard, the sedation, in addition to local anesthesia routinely applied in Italian protocol, significantly reduces pain and ameliorates the pain perception of patients. Concerning the lack of widespread expertise, in Italy a Hub/Spokes model is proposed to standardize the analyses, optimizing the approach to CKD patients and reducing the costs of the procedure. In addition, new tools offer the possibility to evaluate the osteogenic potential or the ability to form bone under normal and pathological conditions, analyzing mesenchymal stem cells and their ability to differentiate in the osteogenic lineage. In the same way, circulating microRNAs are suggested as a tool for exploring osteogenic potential. The combination of different diagnostic approaches and the optimization of the bioptic procedure represent a concrete solution to spread the use of bone biopsy and optimize CKD patient management.

Comparison of the Concept of Command Responsibility in Human Rights Court Provisions

The new spirit of human rights enforcement in Indonesia through the ratification of Law no. 26 of 2000 became the main pillar to accommodate issues that attracted international attention. Law No. 26 of 2000 has shown the importance of regulating human rights enforcement, the regulation is also the main instrument to protect and guarantee human rights enforcement mechanisms in Indonesia. The author takes a legal problem on the comparative law of Law no. 26 of 2000 concerning the Human Rights Court which was adopted from the provisions of the 1998 Rome Statute. Several human rights activists took action, this was because the 1998 Rome Statute provisions were adopted imperfectly in article 42 of Law no. 26 of 2000 which caused problems in the enforcement of the Human Rights Court. Some of the perpetrators of gross human rights violations in Indonesia are generally parties with power or position, who can escape the applicable legal sanctions and are free from responsibility for the actions that have been committed by them or their groups. So it is important for the development of human rights in Indonesia to improve the norms of command responsibility in Article 42 of Law no. 26 of 2000. Based on these issues, the author will integrate several comparative laws and principles to get a concrete solution. The purpose of this research is to build a legal framework to strengthen the enforcement of Indonesian human rights. The methodology that will be used is a normative method with a conceptual approach. The findings of this study reveal that several human rights violations by the Command in Indonesia have not yet been resolved properly and have attracted international attention. In theoretical studies, the existence of the principle of command responsibility is considered difficult to prove in court. The involvement of human rights violators by the TNI command in several cases is evidence that the implementation of the command responsibility mechanism in human rights violations is far from being expected.

CIUDAD LIMPIA VALDIVIA: A MOBILE AND WEB BASED SMART SOLUTION BASED ON FOSS TECHNOLOGY TO SUPPORT MUNICIPAL AND HOUSEHOLD WASTE COLLECTION

Ciudad Limpia Valdivia is a Web and Mobile application which attempts to tackle some of the Municipality of Valdivia in Chile’s waste collection issues. It is based on Free and Open Source Software and it is currently in the last stage of prototyping. The tool is expected to improve the communication between the users and the service provider. It also has educational materials about waste management and other related environmental issues to guide the users to minimize the waste production and optimize the way it is handled before it is collected. The main features of the solution are: a dynamic map viewer showing the position of the Municipality’s waste collection trucks and estimated future trajectories, a form to report illegal dumping microsites, notifications from the Municipality about the status of the service, educational content and contact list of other independent initiatives related to waste collection. The potential impact of the tool was evaluated on the city’s test pilot sector by means of a neighbourhood survey. It showed that the solution might have a positive impact in the coordination in terms of the service operation. The estimation of the trucks’ future trajectory will be developed using machine learning or computational intelligence algorithms. The integration of FOSS technologies has been essential to address challenges found during development as well as to adapt the tool to new scenarios. The feedback from the Municipality and the community has proved to be very important to define a concrete solution.

Latest Classification and Such Functions of Human Hormones

Based on the classification of human hormones, there is no solid idea in most books. In this view, this article could exemplify a concrete solution, especially for medical and university students. Hormones have many life-saving roles in the human body. With the deficiency of hormones, our body might fall into lots of problems. Data analyses of much information from books, articles, online supplements gave different ideas on total hormones. The result suggested that some hormones were secret from the same glands. Out of 110 hormones (when the same hormone came from different sources), exact different types of hormones were 88. Analyzed hormones consisted of four major groups- amine (4 hormones), eicosanoid (4), steroid (15), and peptide were (65) out of 88 endocrine chemicals. The endocrine and reproductive system (56) jointly secreted most of the hormones, and secondly gastrointestinal tract (26 hormones). Besides the organ system or glands, some are come out from the cell, tissue, tissue system, and placenta. This paper also mentions, phenotypically males and females exhibit many differences, hence hormonal analyses; they are more or less the same. For instance, many sex hormones are also present both in males and females. In the future, it needs to enhance more research on the classification of the hormones in the human body.
