Published: April 2019

The corrosion of steel and its alloys is an important problem in industry, especially in acidic environments. Mild steel is one of the important alloys of iron which has many industrial applications because of its excellent mechanical properties, but mild steel is susceptible to corrosion. Corrosion problems need to be a concern and must be handled properly. Hydrochloric acid is widely used for pickling, cleansing, decomposition and metal etching, on the other hand also contributes to corrosion of metal surfaces. Plant extracts investigated the properties, mechanisms of adsorption and efficiency of inhibition as environmentally friendly corrosion inhibitors for various steel materials in different acidic media. The efficiency of corrosion inhibition of steel from plant extracts analyzed ranged from 72-98% and generally as a mixed-type inhibitor. Most of the inhibitors are adsorbed on the steel surface through a physisorption mechanism.
Density-driven correlations in many-electron ensembles: theory and application for excited states
Authors: Gould Tim , Pittalis Stefano
Published: April 2019

Density functional theory can be extended to excited states by means of a unified variational approach for passive state ensembles. This extension overcomes the restriction of the typical density functional approach to ground states, and offers useful formal and demonstrated practical benefits. The correlation energy functional in the generalized case acquires higher complexity than its ground state counterpart, however. Little is known about its internal structure nor how to effectively approximate it in general. Here we show that such a functional can be broken down into natural components, including what we call ``state-'' and ``density-driven'' correlations, with the former amenable to conventional approximations, and the latter being a unique feature of ensembles. Such a decomposition, summarised in eq.(6), provides us with a pathway to general approximations that are able to routinely handle low-lying excited states. The importance of density-driven correlations is demonstrated, an approximation for them is introduced and shown to be useful.

Published: April 2019

Energy harvesting adalah proses mengambil energi dari alam untuk dimanfaatkan sebagai sumber daya alternatif. Dalam dunia telekomunikasi, sebagian besar sinyal seluler yang dipancarkan oleh base transreceiver station (BTS) tidak akan diterima oleh pengguna telepon seluler. Hanya sebagian kecil saja yang dimanfaatkan untuk saling berkomunikasi antara pengguna dan BTS. Sinyal ini dapat dipanen dengan menggunakan antena dengan frekuensi kerja yang sesuai. Sinyal yang akan dipanen adalah sinyal pada frekuensi sekitar 1,8 GHz. Antena log periodic dipole array (LPDA) memiliki gain yang tinggi sehingga dapat memanen sinyal seluler dengan baik jika diarahkan ke sumber sinyal atau BTS. Perancangan antena LPDA dilakukan dengan melakukan simulasi pada perangkat lunak CST. Ukuran antena LPDA dihitung berdasarkan persamaan yang telah ada dan dilakukan optimasi untuk mendapatkan spesifikasi yang diinginkan. Antena LPDA berbahan dasar alumunium. Hasil simulasi memiliki rentang frekuensi kerja pada 1,7764 – 1,9044 GHz dengan bandwidth antena sebesar 128 MHz. Nilai S11 minimum terdapat pada frekuensi 1,8308 GHz sebesar -56,6837 dB. Sedangkan antena fabrikasi memiliki rentang frekuensi 1,738 – 1,846 GHz dengan bandwidth 108 MHz. Nilai minimum S11 sebesar -35,7 dB berada pada frekuensi 1,792 GHz.

Katalis vanadium bekas diperkirakan akan menjadi salah satu sumber utama persediaan vanadium di masa mendatang. Hasil analisis vanadium dalam katalis vanadium bekas menunjukkan bahwa kadar V2O5 nyamasih cukup banyak untuk diambil dan diolah kembali. Dalam penelitian ini, suatu prosedur telah dikembangkan untuk mengesktraksi vanadium dari katalis vanadium bekas berdasarkan prosedur yang dikembangkan oleh peneliti terdahulu. Katalis vanadium bekas uji coba prosedur menunjukkan bahwa metode gabungan ekstraksi vanadium dari katalis vanadium bekas menggunakan pelarut basa Na2CO3 dan H2O2 pada umpan (tahap ekstraksi pertama) dan NaOH (tahap ekstraksi kedua) yang diikuti dengan netralisasi filtrat dengan asam H2SO4  merupakan prosedur terbaik. Lebih lanjut, terdapat tiga variabel yang sangat berpengaruh dalam pengambilan kembali vanadium dari katalis vanadium bekas, yang ditandai dengan nilai probability of being active di atas 50%. Ketiga variabel tersebut adalah temperatur pengadukan pada tahap ekstraksi II, penambahan larutan H2O2 di umpan dan waktu pengadukan pada tahap ekstraksi I dengan nilai probability of being active secara berturut-turut sebesar 100%, 86%, dan 56%. Untuk mendapatkan perolehan vanadium yang lebih tinggi perlu diadakan penelitian lanjutan yang mengoptimumkan  variabel-variabel tersebut.

Trapping Investigation of the GaN HEMT Devices Using the Low Frequency Noise Characterization
Authors: Bouslama Mohamed , Nallatamby Jean-Christophe , Prigent Michel
Published: April 2019

This paper, proposes the characterization of the signature of traps existing in the new AlGaN/GaN HEMT of 0.15 μm ultra-short gate length and 8x50 μm gate width through the output and the input Low Frequency (LF) noise measurement technique. These measurements were performed for varying chuck temperatures (Tchuck) ranging between 25 °C and 125 °C and for the same biasing condition by measuring the output or input noise spectral density. The output drain noise spectral density characteristics demonstrate the existence of an acceptor-like traps. The peak value of those traps shifts towards higher frequencies as the temperature increases. The activation energy Ea around 0.51 eV and the cross section σn around 5x10-15 cm2 were extracted using Arrhenius equation. Furthermore, the input gate noise spectral density characteristics demonstrate the presence of another type of traps. The peak of this traps does not show the frequency shift as the temperature increases. The leakage current measured before and after LF measurements for VGS = -6 V, -7 V and for VDS varying from 0 V to 10 V remains lower than 40 μA/mm.
Inclusive, Responsive, Democratic Local Government Institution and Active Citizens
Authors: Marianata Anita
Published: April 2019

Reform in decentralization and village democratization can be seen in the involvement of villagers in the policy-making process, both in the economic, political and rural development fields. In the community planning process there is widespread (participatory) community involvement. The involvement of citizens in village development is one part of the development goals. Equality, justice, non-violence, tolerance, inclusiveness, transparency, accountability and responsiveness are principles that must be put forward in the village development planning process. The involvement of citizens in village development planning and budgeting aims to ensure and identify what should be the development priorities, policies, programs and activities that require budget or resources. By using a descriptive qualitative approach, this research is expected to be able to understand more deeply about inclusive and responsive democracy carried out by village government institutions and the involvement of villagers' participation. This is one of the first steps that should be taken by the village government in building democracy at the village level.

Published: April 2019

A observação de uma crescente sensibilização quanto à necessidade de realizarmos práticas pedagógicas interculturais para uma educação mais inclusiva com relação aos grupos historicamente subalternizados motivou-nos a reflexão neste artigo. Nos textos das políticas educacionais, especialmente aqueles produzidos a partir de discussões ocorridas na segunda metade da primeira década e primeira metade da segunda década dos anos 2000, verificamos avanços das perspectivas interculturais e inclusivas. É nesse contexto que se situa este trabalho. Seu objetivo é, a partir da análise das Diretrizes Curriculares Nacionais Gerais para a Educação Básica (Resolução CNE/CEB n.º 4/2010), Diretrizes Curriculares Nacionais para o Ensino Médio (Resolução CNE/CEB n.º 2/2012) e das Diretrizes Curriculares Nacionais para a Educação Profissional Técnica de Nível Médio (Resolução CNE/CEB n.º 6/2012), refletir sobre a potencialidade de essas legislações subsidiarem a elaboração de currículos e o desenvolvimento de práticas interculturais e inclusivas. Espera-se, ainda, que esses documentos impactem a construção de identidades descolonizadas, tanto de professores quanto de estudantes, de forma a contribuir para uma formação emancipatória dos sujeitos do processo educativo.
Expert Competence in Forensic Facial Identification: Problem Areas
Authors: Zinin A. M.
Published: April 2019

The article deals with some of the systems of special knowledge that form the basis of competence of an expert performing forensic facial identification. It is observed that the existing general methodological framework, particularly in the areas of anatomy, anthropology, and modern human imaging technologies is inadequate for the analysis of human features in specific forensic contexts. The author therefore argues for the need to develop specialized education courses that could be used in the training of forensic facial identification practitioners.

Development of Criminal Procedure Legislation on Forensic Science, Experts and Specialists
Authors: Makhov Vadim N.
Published: April 2019

Key stages in the establishment and further development of the institution of special knowledge in Russia is analyzed, from the pre-revolutionary period to our days. The procedural status of forensic science, forensic experts and forensic specialists in the Russian criminal procedure is examined. The procedural status of experts and specialists in the Russian criminal procedure is compared to that in other countries. The author observes that in the early stages the functions of knowledgeable persons were not clearly delineated by the law, and there were no regulations on how forensic evidence analysis should be requested and conducted, but by the mid-1920s the terms «forensic science» and «forensic expert» were present in the Russian legislation. The procedure for requesting and conducting forensic examinations was defined starting in 1960; the use of special knowledge in investigative actions became the function of the specialist. The status of the specialist was further elaborated in 1966. With the adoption of the Criminal Procedure Code of the Russian Federation in 2001, the specialist's legal status was expanded, giving them the right to present their opinion and testify on the probative value of evidence, and their rights and responsibilities were refined.
Propaganda as a Category in Forensic Text Analysis
Authors: Baranov Anatolii N. , Parshin Pavel B.
Published: April 2019

The category of propaganda is considered in the paper as a linguistically definable notion. It is demonstrated that being a legal term, this category is significantly influenced by the semantics of the word propaganda as a unit of the Russian literary language. Presented is an analysis of various definitions of propaganda in their historical evolution, from the earliest record of the word in Russian dictionaries to modern lexicographic definitions. Polysemy of the lexical unit “propaganda” is analyzed. Special focus is placed on differentiation of propaganda from other forms of persuasive communication, particularly from advertising, including its political variety. Analysis of the meaning and use of the word propaganda is proposed as a way to objectivize the intuitive labeling of various statements as propagandistic. Our analysis resulted in a list of key properties of propagandistic discourse to be taken into account in the investigation of suspected propaganda of extremism and terrorism, namely, the existence of: (1) a subject of propaganda; (2) an addressee of propaganda, (3) a set of relatively simple and consistent points (describing the desired state of affairs) and supporting arguments; (4) opposing evaluations of the desired situation and its negative alternatives; (5) recurrent and persistent realization of the aforementioned set of points or its fragments in the discourse, with identical of slightly modified argumentation; (6) multiple texts produced within a certain period of time (i.e. the period of a propagandistic campaign); and (7) a practical possibility for disseminating information among multiple people (addressees).
Experimental Validation of a Methodology for Determining Soil pH and Specific Electrical Conductance in Samples of Geological and Soil Evidence in Forensic Environmental Investigations in the Absence of Standard Samples
Authors: Bebeshko Galina I. , Omel'yanyuk Georgii G. , Nikulina Marina V. , Valitova Alsu R.
Published: April 2019

The paper describes an experiment in validation of a forensic methodology for determining the hydrogen potential (pH) and specific conductance (SC) in samples of geological and soil evidence for the purposes of forensic environmental investigation. Validation was aimed at standardizing the conditions of aqueous extract preparation, since the conditions prescribed by corresponding regulations varied significantly. Given the absence of adequate standard samples at the time of the experiment, control samples had to be selected, and reference values of pH and SC in these control samples had to be determined through average values of the overall set of measurements. The experiment consisted of 5 operators independently conducting six parallel analyses of three control samples, each operator working at a different time and using their own assay kits. Both pH and SC values were measured in two different dilutions, each after 5 minutes, 1 hour, and 24 hours of holding time. Statistical calculations of the obtained set of results yielded reference values for target parameters in three control samples for different aqueous extract preparation conditions. It was demonstrated that when the extract is diluted to 1 : 2.5 soil/water ratio, measurements are on average 1.8 times higher for SC, and 0.20 pts lower for pH, compared to 1 : 5 soil/water dilution. Since 1 : 5 is the standard dilution for aqueous extracts, 1 : 2.5 dilutions call for a corresponding adjustment. Acceptable holding time between dilution and measurement has been established to vary between 5 minutes and 1 hour. When re-validated a year later, the obtained mean values of pH and SC in three control samples of soil fit within the uncertainty interval for adopted reference values.The outcomes demonstrate the stability of control sample properties and reliability of the applied methodology.
Forensic Investigation of Crimes Against the Amur Tiger and Other Animals: Problems and Solutions
Authors: Aramilev S. V. , Kiseleva E. S. , Fomenko P. V.
Published: April 2019

The late 20th century saw the development of a new special framework for the conservation of large mammals – both tigers and their prey, mostly ungulates, – along with their habitats in the Far East of Russia. Tightening controls on poaching, illicit trafficking and trade in wild animals and their parts, as well as enforcement of adequate penalties for these crimes rely on effective crime detection procedures and quality forensic investigation, which provides important grounds for prosecution. There are currently only four organizations conducting such forensic investigations within the geographic range of the Amur tiger.

Efforts to facilitate forensic assistance have included production of the monograph “The Basics of Wildlife Forensics”, establishment of a veterinary treatment and diagnostic center for post-mortem examinations and a carcass storage facility for preservation of forensic evidence, and ongoing work to create biorepositories.

However, there is still no streamlined system for state-supported forensic investigation of crimes against wildlife and forensic examinations of wild animals, their parts and derivatives.

Such examinations should be conducted by specialized centers under designated conservation authorities of the constituent subjects of the Russian Federation, similar to the forensic bureaus of the Ministry of the Interior.
Current Issues in Justice and Home Affairs Cooperation between EU Member States Pertaining to Forensic Services and Investigative Operations
Authors: Nikitina I. E.
Published: April 2019

The paper discusses the EU's decision to establish the first supranational law enforcement body – the European Public Prosecutor's Office (EPPO) – and further articulates the notion of “supranationalism”. The author argues for the need to develop a strategic plan for interaction between the Prosecutor General's Office of the Russian Federation and the EPPO to ensure effective oversight over the practice of forensic science and criminalistics, lawfulness of the actions of preliminary investigation units conducting forensic and search operations, and the use of specialized knowledge in transnational crime prevention, detection and response. Adoption of an updated strategy for international cooperation in this field has prompted national jurisdictions to place greater emphasis on the issues of the expert's initiative, proactive forensics, and predictive forensics.

The Legal Category of Authenticity. Current Perspectives
Authors: Krestovnikov O. A.
Published: April 2019

This overview focuses on the conceptualization of authenticity as a practical category that has always preoccupied those pondering the reality of the world as such, and aspiring to make sense of themselves and their purpose in this world. The problem of authenticity is examined from the perspectives of various fields of human knowledge. For instance, in legal philosophy and law enforcement the issue of authenticity is interpreted in strictly utilitarian terms. The subject comes up whenever physical evidence, documents or information need to be tested for authenticity. The current legal understanding of the problem is analyzed to show that it still lacks sophistication.

Special Methods of Forensic Linguistic Analysis and “Expert Phantoms” (Reflections upon Reading the Works of R.S. Belkin's on Criminalistics)
Authors: Galyashina E. I.
Published: April 2019

The article discusses some special methods and approaches to forensic linguistic analysis that may lead to the occurrence of “expert phantoms”, or speculative contradictory findings instead of science-based linguistic facts. The use of linguistic methods that modify the original text as a piece of linguistic evidence, or artificially create a new virtual object (“complex separate text”) by combining different texts, can be seen as the basis for evaluating an expert’s opinion as irrelevant or inadmissible evidence.
R.S. Belkin and the Establishment of Forensic Biology and Forensic Ecology
Authors: Maiorova E. I.
Published: April 2019

Professor R.S. Belkin's role in the development of criminology and forensic science is widely recognized. The theory he advanced to connect criminalistics and the natural sciences was of great importance for the establishment of new forensic disciplines. During his time as head of the department of forensic science theory Professor Belkin focused on newly emerging fields of forensic research and the development of their theoretical foundations. His vision was marked by a deep understanding that ecology is a subfield of biology, but forensic ecology is not part of forensic biology. It is largely due to his talent to anticipate the emergence of new trends in response to the needs of investigative practice that these forensic disciplines were established and continue to develop.
Reinforcing the Octagonal Web Openings of Castellated Beam by Steel Rings
Authors: Al-Thabhawee Hayder W. , Mohammed Abbas A.
Published: April 2019

Castellated steel beams are section steel members with hexagonal or octagonal web openings which they are made from standard hot rolled steel section I or H. The main advantage of these members is their economic material. An additional important advantage is a possibility to guide service ducts through the openings. The presence of the web openings influences the members’ failure behavior around the openings, new local failure modes will come into existence, such as the buckling of the web post between the openings, or yielding around the openings. Castellated beams with octagonal openings usually fail due to web post-buckling because of the increase in depth. The current study focused on improving the behavior of the castellated beam with octagonal openings using steel ring stiffener and adjusting the best dimension and distribution for the stiffeners. All the models of specimens have been fabricated from a parent I section (IPE 140). The models have been modeled and analyzed using finite element software ANSYS (version 15). The analysis results showed that reinforcing octagonal castellated beams by adding steel ring stiffeners around octagonal web opening was very active way to increase the ultimate load for long span, where the ultimate load of reinforced octagonal castellated beam increased up to (286%) compared with parent I-section beam. Economically, the percentage of additional steel material which used to expansion and reinforce the castellated beams (spacer plate and steel ring stiffeners) was (36%) when compared with the weight of parent I-section beam. While the allowable load at deflection (L/180) was (260 %) compared to the allowable load of parent section at the same deflection. The gained benefit was increasing the ultimate and allowable load of reinforced octagonal castellated beams by (186%) and (160%) respectively by using additional steel material only (36%) from the weight of parent I- section, which the additional steel material consisted from the spacer plates and steel rings. Also, the results indicate that the best dimensions for the ring were when thickness equal to the web thickness of the parent section and the width equal to the half of the parent section flange width.

Published: April 2019

Cayenne pepper storage at room temperature will cause physical, mechanical,chemical or microbiological damage in short time. In room terperature conditions cayennepepper can only survive for 2-3 days and finally will be decay. The use of packaging canincrease the small chilli storeability, because packaging can reduce the level of exposure toenvironmental changes. This research aims to study the quality changes of cayenne pepperduring storage on room temperature. The results showed that losses of cayenne pepper weightincreased with increasing duration of storage. Cayenne pepper storaged for 8 days causedweight loss of 24.25%. The use of perforated plastic packaging can reduce the weight loss by16.82%, much lower than the control of 31.67%. The pH of chili during the 8-days decreasedwith value of 6.55 while the control was 6.7. The pH experienced decreased of 2.23% fromthe control (without packaged). While the number of colored cayenne pepper increasedduring storage from 40% in control treatment and 60% in the packaging.

The purpose of this research is to know and study various combination of carrot flour to chemical quality and organoleptic quality of tuna nugget. This study used Completely Randomized Design (RAL) with 4 treatments, and 4 replications. The research that will be done is as follows: R0 = 15% tapioca starch + 5% cornstarch + 0% carrot flour; R1 = 10% tapioca starch + 5% maize starch + 5% carrot flour; R2 = 5% tapioca starch + 5% maize flour + 10% carrot flour and R3 = 5% tapioca starch + 15% carrot starch. Each treatment was repeated four times, so there were 16 experimental units. To know the effect of the experiment, then the diversity test is done and if the result of the diversity test show the real effect, then continued with the test of the Least Significant Difference (LSD). The results showed that the addition of various carrot starch combinations had significant effect on protein content, crude fiber and tuna nugget fat but no significant effect on water content, b-carotene and organoleptic qualities of tuna nugget. a 10% tapioca starch combination, 5% cornstarch and 5% carrot flour give the highest levels of protein, coarse fiber, tuna nugget fat. Combination of 5% tapioca starch and 15% carrot flour gave the organoleptic qualities of tuna nuggets tend to be favored by panelists.

DNA extraction is needed in the analysis using the Loop-mediated isothermal amplification (LAMP) method because this method identifies nucleic acids. Some extraction methods that can be selected including commercial kits extraction method and phenol-chloroform extraction method. The purpose of this study was to obtain the best quality DNA extract between the two extraction methods. The DNA extraction process produced DNA concentrations between 31.06 - 410.18 ng / ml for the commercial kit DNA extract and 212.60 - 1502.30 ng / ml for the phenol-choroform DNA extract, while the purity of DNA were 1.82-2.02 for commercial kit DNA extract and 1.93-2.02 for phenol-chloroform DNA extract. The concentration and purity of extracts produced from both methods meet the requirements for molecular analysis. The purity and visualization results of commercial kit DNA extract are better than those produced from extraction from the phenol-chloroform method. DNA extract obtained from the commercial kit method was chosen to be used in the amplification stage of the method (LAMP).
