Authors: Wahyuni Siti , Ravichanthiran Jeewena
Published: May 2020

Introduction: Thermoplastic nylon denture base is processed through injection molding process. This manipulation technique produces non-biodegradable nylon wastes which have to be recycled. Recycling of nylon wastes is feasible due to the linear molecular structure of thermoplastic nylon. This study aimed to know the effect of adding virgin nylon into recycled nylon on the fatigue strength of thermoplastic nylon denture base. Methods: This research was experimental laboratory research using 27 samples of thermoplastic nylon with three different groups (100% virgin nylon, 100% recycled nylon and combination of 60% of virgin nylon with 40% of recycled nylon) using injection molding technique. The test results were analyzed using one-way ANOVA test to know the differences in the mean value of the fatigue strength of each group and LSD test to know the effect of adding 60% of virgin nylon into 40% of recycled nylon. Resuts: Results showed significant results (p < 0,05), as well as LSD test that showed there is effect of adding 60% of virgin nylon into 40% of recycled nylon on the fatigue strength of thermoplastic nylon denture base. Conclusion: The combination of 60% of virgin nylon with 40% of recycled nylon showed higher fatigue strength than the recycled nylon.

Introduction: Cymbopogon nardus is a strong aromatic plant with relevant medicinal properties due to its essential chemical compounds and its potential therapeutic effects. This study was aimed to evaluate the antimicrobial activities of citronella essential oil against several oral pathogens and to identify the volatile compounds. Methods: The essential oil of C. nardus was purchased from Excellent Wisdom Sdn. Bhd., Malaysia. The source of raw material was collected from Malacca, the southern region of Malaysia, and the company made its taxonomic identification. An experimental in-vitro study was conducted on the essential oil processed from C. nardus genus Cymbopogon of Poaceae family. The in-vitro antimicrobial activities of C. nardus essential oil were evaluated against Streptococcus mutans (ATCC 25175), Streptococcus sobrinus (ATCC 33478), and Candida albicans (ATCC 10231) using agar well diffusion assay. The identification of the volatile compounds was performed using gas chromatography-mass spectrometry (GC-MS). Results: The C. nardus essential oil exhibited inhibitory activity against C. albicans at the concentration of 6.25%, whereby the inhibitory activity against S. mutans and S. sobrinus began at the concentration of 25%. The antimicrobial activity of C. nardus essential oil was statistically significant at the concentration of 50% in all tested pathogens. The GC-MS analysis of the C. nardus essential oil revealed the presence of few constituents, which include monoterpenes, diterpenes, sesquiterpenes and phenolic compounds. Monoterpenes were the major identified terpenoids and contributed to 54.45% of the total volatile composition. The main identified monoterpenes were citronellal (11.35%), z-Citral (11.34%), β-Myrcene (6.70%), and β-Trans-ocimene (6.03%), which was the first time β-Myrcene and β-Trans-ocimene was found in high percentage. Conclusion: C. nardus essential oil is an active antibacterial agent against several oral pathogens, and the percentages of active volatile compounds are different within different origins.

Published: May 2020

In this study, Wood Dust (WD)/Phenol Formaldehyde (PF) and Coir Pith (CP)/PF composites were hybridized with the Prosopis Juliflora Fiber (PJF) to obtain the hybrid composites. Composites were prepared by hand moulding technique. The weight percentage of particles and fibers are fixed in the ratio of 1:1. Mechanical properties such as tensile, flexural and impact strengths were evaluated as a function of the particle and fiber loadings. The results show that the properties of both the WD and CP composites obviously improved by the addition of the PJF. The improvement in WD/PF composites was obviously higher than the CP/PF composites for all loadings. The WD/PJF/PF hybrid composites exhibited better tensile (strength of 48.9 MPA and modulus of 1262.1 MPa, respectively), flexural (strength of 55.4 MPa and modulus of 1344.3 MPa, respectively), and impact properties (1.32 KJ/m2).Â

Published: May 2020

The spindle error contributes to 25 percent of the error sources of the work piece in- accuracies. The 70 percent of the spindle errors are due to thermal errors that occurs in the spindle. The heat generation in high-speed built-in motorized spindle is of important concern in high speed machining. It is necessary to predict the heat generation in spindle body virtually so as to judge machine capability. The thermal prediction will also help in taking precautions to avoid inaccurate parts being produced as well to avoid the chances of bearing seizure leading to catastrophic failure of spindle. In this paper the thermal behavior of high-speed motorized spindle is investigated through three dimensional analysis and experimentation validation is given for the same.
Table Substitution Box Method for Increasing Security in Interval Splitting Arithmetic Coding
Authors: Kiruba E.Wiselin , K. Ramar
Published: May 2020

Amalgamation of compression and security is indispensable in the field of multimedia applications. A novel approach to enhance security with compression is discussed in this Â research paper. In secure arithmetic coder (SAC), security is provided by input and output permutation methods and compression is done by interval splitting arithmetic coding. Permutation in SAC is susceptible to attacks. Encryption issues associated with SAC is dealt in this research method. The aim of this proposed method is to encrypt the data first by Table Substitution Box (T-box) and then to compress by Interval Splitting Arithmetic Coder (ISAC). This method incorporates dynamic T-box in order to provide better security. T-box is a method, constituting elements based on the random output of Pseudo Random Generator (PRNG), which gets the input from Secure Hash Algorithm-256 (SHA-256) message digest. The current scheme is created, based on the key, which is known to the encoder and decoder. Further, T-boxes are created by using the previous message digest as a key. Â Existing interval splitting arithmetic coding of SAC is applied for compression of text data. Interval splitting finds a relative position to split the intervals and this in turn brings out compression. The result divulges that permutation replaced by T-box method provides enhanced security than SAC. Data is not revealed when permutation is replaced by T-box method. Security exploration reveals that the data remains secure to cipher text attacks, known plain text attacks and chosen plain text attacks. This approach results in increased security to Interval ISAC. Additionally the compression ratioÂ  is compared by transferring the outcome of T-boxÂ  to traditionalÂ  arithmetic coding. The comparison proved that there is a minor reduction in compression ratio in ISAC than arithmetic coding. However the security provided by ISAC overcomes the issues of compression ratio inÂ  arithmetic coding.Â

Published: May 2020

Drug discovery is mainly the result of chance discovery and massive screening of large corporate libraries of synthesized or naturally-occurring compounds. Computer aided drug design is an approach to rational drug design made possible by the recent advances in computational chemistry in various fields of chemistry, such as molecular graphics, molecular mechanics, quantum chemistry, molecular dynamics, library searching, prediction of physical, chemical, and biological properties.Â  The structure of a chemical compound can be represented by a graph whose vertex and edge specify the atom and bonds respectively. Topological indices are designed basically by transforming a molecular graph into a number. A topological index is a numeric quantity of a molecule that is mathematically derived from the structural graph of a molecule. In this paper we compute certain topological indices of pyrene molecular graph. The topological indices are used in quantitative structure-property relationships (QSPR) and quantitative structure-activity relationships (QSAR) studies.Â

(Re)pensar la intermediación laboral del Servicio Público de Empleo en Argentina a partir de la experiencia internacional
Authors: Sconfienza María Eugenia
Published: May 2020

Argentina presenta un escenario en el cual un segmento cuantitativamente significativo se encuentra en situación de desempleo, subocupación involuntaria e informalidad. La escasez de empleo agravada de mecanismos de reclutamiento altamente restrictivos para los trabajadores de menor calificación, redundan en una desigualdad en el acceso al empleo, cada vez más marcada.Teniendo en consideración que el argentino es un Servicio Público de Empleo con apenas algo más de quince años de existencia, el camino recorrido por otros países puede ser un invaluable consejero para pensar adaptaciones de experiencias exitosas al caso local. En este compendio analítico, haciendo uso de una metodología de análisis de casos, se plantea un ejercicio que permite, en una primera instancia dimensionar el diagnóstico de situación local y luego, proyectar la potencialidad de adaptación de estrategias más efectivas de intermediación laboral para el acceso al empleo de personas en situación de exclusión.Entre los hallazgos principales, la evidencia internacional muestra por una parte, que las Políticas Activas de Mercado de Trabajo deben ser enmarcadas por una visión en la cual la inclusión sea considerada estratégica para el crecimiento de un país. Por otra parte, diversas experiencias de políticas de intermediación laboral, pueden ser interesantes de adaptar e implementar a la realidad local. Es el caso del profiling, el acompañamiento reforzado, el aprovechamiento de herramientas tecnológicas, y la generación de alianzas con el tercer sector y con el sector privado.
New Governance Mechanisms Contributing to the Integration of National Climate Change Adaptation and Mitigation Policies in the Brazilian Amazon
Authors: Ferreira Costa Carlos Germano
Published: May 2020

Research in the field of Global Environmental Governance (GEG) pays considerable attention to the emergence of New Governance Mechanisms (NGM). NGM poses profound challenges to governments and institutions in the Developed and Developing world alike, corresponding to new ways of participation. This article seeks to contribute to the debates on NGM by analyzing a municipal-level environmental governance scheme based on deforestation-free commitments emerged in 2011, in Brazil, that has successfully helped to reduce deforestation in the participant municipalities; the Programa Municípios Verdes (PMV). We also shed some lights on the risks represented by promises of changes in federal environmental legislation by the newly elected government of Brazil. It is secondary research based on official data analysis that provided a cost-effective way of gaining a broad understanding of the integration of multi-level climate change mitigation and adaptation policies as well as a report of the governance of policy instruments in local governance schemes. Methodologically we rely on the method of content analysis, based on the study of the PMV Statistical Database, that gives visibility to a broad range of environmental, social, and territorial data and information for the 144 municipalities of the Pará State, through six different types of official reports.

Prace nad kodyfikacją prawa karnego procesowego w Polsce w latach 1919–1928
Authors: Koredczuk Józef
Published: May 2020

In his contribution, the author presents the work on the codification (initially on the Act) of procedural criminal law in Poland in the years 1919–1928. Those works were initially led by the Criminal Department of the Codification Committee, and then by the Criminal Proceedings Section of the Codification Commission. The first period of the work on the criminal procedure law was characterized by some disputes between the members of the Department, i.e. supporters of the classical school (E. Krzymuski) vs. the sociological school (J. Makarewicz), the discussion aiming at defining the relationship of procedural criminal law and substantive criminal law. The work on the draft law was carried out faster after the appointment (on 16 July 1920) of the Criminal Proceedings Section, which in 1924 published the first version of the draft criminal law bill. E. Krzymuski, A. Mogilnicki, Z. Rymowicz and E.S. Rappaport had played the main role in the development of the project. After a very deep criticism in the columns of Gazeta Administracji i Policji Państwowej [The Gazette of State Administration and Police], Ruch Prawniczy, Ekonomiczny i Socjologiczny [The legal, economic and sociological movement] and Palestra [The bar], the project was rejected. Only the second version of the bill prepared in 1925-1926, re-worked by the committee composed of W. Makowski, A. Mogilnicki and S. Śliwiński (appointed by the Minister of Justice), became the basis for the President of the Republic of Poland to adopt the first Polish Code of Criminal Procedure of 19 March 1928.
Od systemu celkowego do systemu dozoru elektronicznego. Zmiany w sposobie wykonywania kary pozbawienia wolności
Authors: Nikołajew Jerzy
Published: May 2020

The evolution of the methods for execution of the custodial penalty demonstrates changes in the treatment of convicts. In the historically oldest systems, the aspect of subjectivity of convicts was completely omitted in favour of their complete isolation (objectification), which resulted in the lack of corrective effects. It was only later that the system of progression in its various forms was adopted, which allowed strengthening of the convicts’ position by appreciation of their work and education as well as gradual mitigation of the effects of prison isolation. Finally, the concept of executing a penalty outside the prison in the electronic surveillance system was adopted, which departed from the absolute necessity of imprisonment towards more socially effective probation measures.

Zmiany społeczno-polityczne przeprowadzone przez Ministerstwo Administracji Publicznej w latach 1944–1950 dotyczące spraw Kościołów i związków wyznaniowych w Polsce
Authors: Włodarczyk Edyta
Published: May 2020

The Ministry of Public Administration was established pursuant to the Act of 31 December 1944 on the appointment of the Interim Government of the Republic of Poland. The matters arising from the relations between the State and the Churches and religious denominations were handled by Department V, which in 1946 consisted of two sections addressing Christian and non-Christian denominations, respectively. The Socio-Political Departments in the Provincial Offices, which employed officials responsible for matters relating to religious denominations, were subordinate to Department V. The same held true in Starostwa Powiatowe [County Offices]. In 1947, Department V was divided into three units addressing matters of the Catholic Church, Christian Denominations and Non-Christian denominations, respectively, and one year later still one more department, i.e. the Department of General Matters, was established. Since 1947 matters relating to religious denominations fell within the competences of Department IV. The Department of Religious Denominations in the Ministry of Public Administration from its beginnings was responsible for shaping the policy of the State towards religious denominations. The aforementioned policy was supposed to be concordant with the directives and principles of the communist party. The socio-political reforms conducted by the Ministry of Public Administration in relation to the Churches and religious associations were one of the means of repression, which within the years 1944-1950 was in its initial phase based on the trial-and-error method. However, it was the cooperation of the Ministry with Urząd Bezpieczeństwa Publicznego [Public Security Office], and later the establishment of Urząd ds. Wyznań [Office in charge of Religious Denominations] in 1950 which changed and regulated actions of the communist authorities towards the Churches and religious associations in Poland regarding the matters concerning the relations between the State and the Church and religious associations. From then on the competences to date of Department IV of the Ministry of Public Administration were transferred onto the Office in charge of Religious Denominations.

Authors: Pączek Marcin
Published: May 2020

The ability of a state to decide freely on the conditions of obtaining or forfeiting its national citizenship has always been perceived as a core element of sovereignty. Within the legal framework of the EU, the member states have remained competent to regulate the question of who qualifies as a national. However, taking into account that EU citizenship is founded on citizenships of the member states, it is incumbent on them to determine who is to be classified as an EU citizen and consequently, who can enjoy the accompanying rights. The purpose of this paper is to investigate the degree to which the member states’ competence to regulate nationality matters has been affected by the introduction of EU citizenship.

Drilling activity in deep formation usually gave greater challenges to the engineer due to its high pressure and temperature. To minimize this problem, drilling mud needs to be modified into a certain condition where it should be performed well in those extreme situations. The drilling mud quality does not significantly decrease, it simply requires better quality of mud at certain points at high temperatures. Certain additives are needed to maintain their performance. Therefore, this study aims to improve the quality of drilling mud by adding additives from carbon powder originating from coconut shells. Coconut shells are burned and processed until they become nanometer-sized, then used as additives in drilling mud. Then, several analyses such as XRD, SEM, as well as the rheology of drilling mud are evaluated. XRD analysis result shows the element from the coconut shell powder was graphite. Laboratory analysis results indicate that drilling mud with coconut shell powder provides better rheological value compared to the same drilling mud without the additives. It was observed that the mud with coconut shell powder performed better at high pressure.

[EN] It was acknowledged that, the Hang Nadim International Airport’s aircraft movements increased significantly at recent 10 years period. The shift in aircraft dimensions and weights have raised questions whether or not the existing apron pavement dimensions are sufficient for accommodating the increase aircraft parking demands and to bear aircraft load changes. The purpose of this research is to evaluate and analyze the apron dimensions and pavement thickness at Hang Nadim Airport. This research was used two relevant methods as guidelines for calculating this apron dimension and thickness; ICAO (International Civil Aviation Organization) Anex 14 2013 and FAA (Federal Aviation Administration) 150/5320-6d. It was calculated that the apron dimension need to be expanded to 1600 m x 150 m for accommodating 31 aircraft parking in 2025 (11 units B747- 300 + 16 units B737-900 + 4 units F27). The apron thickness would be 46.2 cm of base course and 10 cm of subbase course.

Hidrologi suatu Daerah Aliran Sungai (DAS) rumit untuk diprediksi karena kekurangan data dan membutuhkan biaya yang mahal. Pada penelitian ini mengambil lokasi di sub DAS Rokan Hulu stasiun Pasir Pengaraian yang hampir setiap tahun terjadi banjir. Perencanaan dan pengolahan sumber daya air di suatu wilayah daerah aliran sungai sangat penting, maka dari itu perlunya mengetahui karakteristik suatu DAS. Perencanaan dan pengolaan sumber daya air memerlukan data debit aliran yang lengkap. Pada sub DAS ini data hujan, data debit dan data klimatologi menggunakan periode data sepuluh tahun yaitu dari tahun 2008-2017. Pemodelan hidrologi dilakukan pendekatan dengan beberapa metode, salah satunya metode soil moisture accounting di program HEC-HMS yang mana metode tersebut mensimulasikan suatu pergerakan air pada vegetasi, permukaan tanah dan di bawah permukaan tanah. Penyusunan periode kalibrasi dan verifikasi disusun dalam sembilan skema yang diharapkan mampu menghasilkan hasil yang paling optimal. Sembilan skema untuk Kalibrasi dan Verifikasi ini menggunakan metode objective function yaitu percent error in discharge volume. Skema yang paling optimal adalah skema VII (7 tahun kalibrasi 3 tahun Verifikasi), dengan nilai verifikasi 10,1%”Baik” dan Kalibrasi 0,0% “Sangat Baik”.

The novel virus such as corona virus 2019 is the main cause of the disease that is declared by the WHO (World Health Origination). Some other virus similar to this virus were also discovered in initial year of 21th century such as SARS-CoV in 2003, HCoV NL63 in 2004, HKU1 in 2005, MERS-CoV in 2012, and SARS-CoV-2 in 2019. The first few cases of covid-19 were detected from direct contact to the infected animal to human which is also called as animal to human transmission. Due to direct exposure of this virus to infected animals the human to human transmission of the virus is as well possible, which is also likely to be consider and measured as core form of transmission. According to the reports of WHO by 26 February 2020, patients suffering from COVID-19 reduced gradually in China but rapidly increased in countries like Italy, Iran and South Korea. The infection caused by the COVID 19 is detected by looking at the symptoms and it ultimately confirmed by the reverse transcription polymerase chain reaction (rRT-PCR) of infected secretions with 71% sensitivity and computed tomography scan with 98%.  The antimalarial medicate, hydroxychloroquine, is authorized for the chemoprophylaxis and treatment of intestinal sickness and as a disease changing antirheumatic drugs. Pharmacological demonstrating dependent on observed drug absorptions and in vitro drug testing propose that prophylaxis with hydroxychloroquine at affirmed portions could anticipate SARS-CoV-2 contamination and improve viral shedding. Clinical preliminaries of hydroxychloroquine treatment for COVID-19 pneumonia are in progress in China (NCT04261517 and NCT04307693).

Published: May 2020

All legal systems have their own solution for the treatment of the essential change of circumstance subsequent to the conclusion of the contract. Some of them allow for the judicial amendment of the contract, if the conditions of the clausula rebus sic stantibus are fulfilled.  There are other states, where the possibility to modify the contract by judicial act in case of an essential change of circumstances subsequent to the contract conclusion has only recently been recognised by the national legislation. In the following, it is to be reviewed how and by what means and models English law treats those changes of circumstances which occur after the conclusion of the contract and significantly reshape the contractual relationships.

Authors: Almeida Sheila Alves , Rodrigues Giselle Barbosa Andrade
Published: May 2020

Esta pesquisa tem como objetivo apresentar um panorama da produção de artigos, dissertações e teses cujo instrumento metodológico se fundamenta nos desenhos das crianças sobre animais. Para tanto, foi realizada uma revisão bibliográfica na área de ensino de ciências nos últimos 12 anos. Os critérios para a seleção dos estudos foram: pesquisas envolvendo sujeitos de 3 a 11 anos de idade; pesquisas cujo instrumento metodológico fosse o desenho; pesquisas na área de ciências com o objetivo de investigar a representação de animais pelas crianças. Em seguida, foram identificados os recursos metodológicos, os espaços de produção das pesquisas e como são analisadas as representações das crianças nos desenhos. Por fim, considera-se que os autores se restringiram à observação de aspectos morfológicos dos animais e não aos aspectos cognitivos e psicológicos do desenho infantil. O conceito de representação é entendido como uma relação de semelhança entre os aspectos morfológicos dos animais e a imagem que as crianças apresentam deles nos desenhos.
