Authors: Bozduman Hanife Çağıl , Afacan Erkan 
Published: May 2020

Abstract
Cryptology is defined as the science of making communication incomprehensible to third parties who have no right to read and understand the data or messages. Cryptology consists of two parts, namely, cryptography and cryptanalysis. Cryptography analyzes methods of encrypting messages, and cryptanalysis analyzes methods of decrypting encrypted messages. Encryption is the process of translating plaintext data into something that appears to be random and meaningless. Decryption is the process of converting this random text into plaintext. Cloud computing is the legal transfer of computing services over the Internet. Cloud services let individuals and businesses to use software and hardware resources at remote locations. Widespread use of cloud computing raises the question of whether it is possible to delegate the processing of data without giving access to it. However, homomorphic encryption allows performing computations on encrypted data without decryption. In homomorphic encryption, only the encrypted version of the data is given to the untrusted computer to process. The computer will perform the computation on this encrypted data, without knowing anything on its real value. Finally, it will send back the result, and whoever has the proper deciphering key can decrypt the cryptogram correctly. The decrypted result will be equal to the intended computed value. In this paper, homomorphic encryption and their types are reviewed. Also, a simulation of somewhat homomorphic encryption is examined.

Published: May 2020

Abstract
This article presents the application of Chaboche nonlinear kinematic hardening model in simulations of uniaxial ratcheting. First, the symmetrical strain-controlled cyclic tension/compression tests for PA6 aluminum samples were done. Using the experimental stress–strain curve, initial material hardening parameters were determined by the ABAQUS software. The experimental curve was compared with the numerical one. For better fitting of both curves, the optimization procedure based on the least-square method was applied. Using the determined hardening parameters, numerical simulations of the ratcheting were done by the finite element analysis software. Numerical results were then compared with the experimental data obtained in the stress-controlled cyclic loading test.
Characterizing Positioning Errors When Using the Second-Generation Australian Satellite-Based Augmentation System

Published: May 2020

Abstract
Fault detection and exclusion (FDE) is the main task for pre-processing of global navigation satellite system (GNSS) positions and is a fundamental process in integrity monitoring that is needed to achieve reliable positioning for applications such as in intelligent transport systems. A widely used method is the solution separation (SS) algorithm. The FDE in SS traditionally builds the models assuming positioning errors are normally distributed. However, in urban environments, this traditional assumption may no longer be valid. The objective of this study is to investigate this and further examine the performance of alternative distributions, which can be useful for FDE modelling and thus improved navigation. In particular, it investigates characterization of positioning errors using GNSS when the Australian satellite-based augmentation system (SBAS) test bed is used, which comprised different positioning modes, including single-point positioning (SPP) using the L1 global positioning system (GPS) legacy SBAS, the second-generation dual-frequency multi-constellation (DFMC) SBAS service for GPS and Galileo, and, finally, precise point positioning (PPP) using GPS and Galileo observations. Statistical analyses are carried out to study the position error distributions over different possible operational environments, including open sky, low-density urban environment, and high-density urban environment. Significant autocorrelation values are also found over all areas. This, however, is more evident for PPP solution. Furthermore, the applied distribution analyses applied suggest that in addition to the normal distribution, logistic, Weibull, and gamma distribution functions can fit the error data in various cases. This information can be used in building more representative FDE models according to the work environment.

Abstract
The purpose of the work was to evaluate the Fe-chelating activity of freeze drying assisted ultrasonicated hydroethanolic leaf extracts of Conocarpus lancifolius Engl. along with 1H-NMR based classification of metabolites in most active extract. The finding revealed that 60% ethanolic extract was the most active fraction regarding Fe-chelating activity with value of 75.4 ± 0.6% followed by 80% ethanolic extract having chelating value of 69.24±1.02%. The least Fe-chelating activity was exhibited by aqueous extract. The statistical analysis revealed that the Fe-chelating activity by 60% ethanolic extract was significantly higher than other fractions except EDTA which was used as standard chelating agent. The 1HNMR technique predicted the presence of aromatic secondary metabolites of polyphenolic origin due to numerous peaks in respective regions. The peaks in carbohydrate and organic acid regions were also observed. The research outcomes suggested that C. lancifolius may be workable choice to move further for the development of cure and management practices for iron load based oxidative stress oriented diseases including diabetes mellitus type II.

Authors: Bouchetat Fawzia , Aissat Abdelkader , Boutellaa Sana , Bellah Safa 
Published: May 2020

Abstract
The experiment was conducted at the level of a pilot farm located in eastern Algeria under a humid bioclimatic stage, during two successive crop years. The study focused on a F1 generation of barley (Hordeum vulgare L.) consisting of twelve hybrids from a complete diallel cross between the two locals varieties (Saida and Tichedrett) and two other introduced varieties (Nadawa and Fouara). The aim was to determine the value of parental genotypes as genitors and to analyze their descendants, while evaluating the phenotypic variability of ten quantitative variables. Analysis of the variance revealed a significant difference for the whole of parameters studied in the parents as in their descendants. Additive and non-additive effects are involved in the genetic control of the analyzed variables. The Hayman model (1954) seems acceptable for five variables on ten variables studied for which additive effects are more important than dominance effects. The analysis of the heterosis effect was significant for the characters tested. For the productivity of the plant, eight hybrids on twelve have expressed a positive heterosis compared to the mid- parent, six combinations on twelve have registered a positive heterosis compared to the over-batter parent and compared to the best variety with an overall heterosis of 17.53%.

Abstract
Currently, scientists are striving to produce innovative textile materials characterized by special properties. Therefore, attempts have been made to use physical and chemical vapor deposition techniques to modify the surface of textile materials, i.e., nonwovens, fabrics, and knitted fabrics. By using these techniques for modifying the basic materials, researchers have obtained textiles with novel properties, which are used in shielding materials, textronics, or clothing, as well as in specialized accessories. The PVD process can be applied for almost all materials. The physical vapor deposition process allows for obtaining layers of different thicknesses and with various physical and chemical properties. This article is a review of the latest state of the art on the use of various methods of physical vapor deposition in textiles destined for different purposes.
A Method of 1D UVC Radiation Dose Measurement using a Novel Tablet Dosimeter
Authors: Sąsiadek Elżbieta , Kozicki Marek 
Published: May 2020

Abstract
In this work, a method for the measurement of one-dimensional (1D) UV radiation dose is described. It comprises a new tablet dosimeter that measures the dose using reflectance spectrophotometry. The tablet dosimeter elaborated is a solid structure with a cylindrical form and has been manufactured with polycaprolactone (PCL) doped with a representative of tetrazolium salts: 2,3,5−triphenyltetrazolium chloride (TTC). The PCL used makes the dosimeter biodegradable and therefore proecological. The TTC dopant is distributed uniformly in the whole PCL tablet, and the whole tablet changes color to red under UVC irradiation. The intensity of this color increases if the PCL–TTC tablet absorbs higher doses. The color of the tablet is stable for at least 30 days after irradiation. It is proposed that the PCL-TTC tablet be used for measurement with reflectance spectrophotometry in order to determine the reflectance of light versus the absorbed dose in a fast and easy manner. On this basis, the PCL-TTC tablet could be characterized by providing information on its dose range, which amounted to 0–2 J/cm2. Moreover, other parameters were derived, such as dose sensitivity, quasilinear dose range, and dose threshold. The morphology of the tablets studied using scanning electron microscopy revealed their high porosity, which however did not influence the reflectance measurements with the aid of the chosen instrument. UVC irradiation at a dose (15 J/cm2) much above the PCL-TTC tablets’ dose range did not alter the morphology of the tablets. The PCL-TTC tablet read with reflectance spectrophotometry is shown to be a promising and fast method for 1D UV dose measurements.

Published: May 2020

Abstract
Aerogels are characterized by excellent insulation properties and a good resistance to high and low temperatures. The objective of this study was to investigate the effects of silica aerogel on thermal properties of textile–polymer composites. Aerogel was applied in protective clothing fabric to improve its heat resistance. The composites were produced by coating a fabric made of meta-aramid (polyamide–imide) yarns with a dispersion of polychloroprene latex and synthetic resins or an acrylic–styrene dispersion with aerogel (100–700 μm particle size). The composites were subjected to thermal radiation (20 kW/m2) and their thermal properties were determined by thermogravimetry/derivative thermogravimetry (TG/DTG). Scanning electron microscopy/X-ray energy dispersive spectroscopy (SEM/EDS) was used to characterize the microstructure and study the elemental composition of materials. The thermal conductivity and resistance of composites were measured with an Alambeta apparatus. The tests indicated an increase in resistance to thermal radiation by approximately 15–25%. In TG/DTG analysis, the initial temperature for an unmodified fabric was 423.3°C. After modification, it decreased to 361.8° and 365.3°C for composites with 7 and 14% of aerogel, respectively. SEM images revealed a reduction in aerogel particle size.
Yoga and relaxation for promoting public health: A review of the practice and supportive research
Authors: Stec Krzysztof 
Published: May 2020

Summary
The purpose of this review is to present yoga as an important tool for both disease prevention and health care. Yoga involves a holistic approach that lacks the mechanistic fragmentation of the impact on individual organs and body systems, which arises from much of the specialization found in modern medicine. Lifestyle diseases are increasingly a problem. The incidence of diabetes, hypertension, atherosclerosis, cancer, mental illness and obesity is increasing worldwide. This is true even of countries that, until recently, followed a traditional way of life. Technology, the pace of life, stress, and reduced physical activity serve to degrade the general level of health in societies across the globe. In Western societies, these factors have raised the demand for preventive and therapeutic antidotes, leading Westerners to turn to traditional yoga, which is, however, often modified to the point of distorting its essence. In its original nature yoga is a non-religious, psychosomatic system based on natural laws, inspired by science to act on the body in a way that is integrated into the natural world. The system of Ayurvedic medicine works in parallel with yoga, aiming at the same holistic effect. Both it and the various elements of yoga, in particular asanas (postures), are the means of effecting beneficial changes in psychosomatic functioning. Yoga itself relaxes and strengthens physical movement, focusing particular attention on the mobility of the spine. It is also the perfect medium for achieving mental balance. These properties of yoga have made it useful in the treatment of cancer and other modern diseases, in slowing the body’s aging process, and in achieving general welfare and well-being. More intense forms of yoga practice, such as the ancient method of fitness training called Suryanamaskar, have demonstrated their effectiveness in preventing and treating cardiovascular diseases, respiratory ailments and other conditions.
Moral Cognition in Criminal Punishment
Authors: Steffen Jason R. 
Published: May 2020

Abstract
Scholars often appeal to Kant in defending a retributivist view of criminal punishment. In this paper, I join other scholars in rejecting this interpretation as insufficiently attentive to Kant's wider theory of justice, particularly as found in the Rechtslehre, a section of the Metaphysics of Morals. I then turn to the Tugendlehre, where I examine analogies between Kant's treatments of morality and justice. In particular, I argue that Kant's own views about conscience and moral cognition should cause us to rethink the importance of lex talionis (an integral retributive principle) in the criminal justice system, and to adopt a more merciful attitude toward punishable criminals than we might otherwise be inclined to do. I end with a few policy proposals aimed at encouraging such moral cognition in contemporary Anglo-American criminal justice systems
A Hybrid Technique for Server Consolidation in Cloud Computing Environment
Authors: Vijaya C. , Srinivasan P. 
Published: May 2020

Abstract
The goal of data centers in the cloud computing environment is to provision the workloads and the computing resources as demanded by the users without the intervention of the providers. To achieve this, virtualization based server consolidation acts as a vital part in virtual machine placement process. Consolidating the Virtual Machines (VMs) on the Physical Machines (PMs) cuts down the unused physical servers, decreasing the energy consumption, while keeping the constraints for CPU and memory utilization. This technique also reduces the resource wastage and optimizes the available resources efficiently. Ant Colony Optimization (ACO) that is a well-known multi objective heuristic algorithm and Grey Wolf Algorithm (GWO) has been used to consolidate the servers used in the virtual machine placement problem. The proposed Fuzzy HAGA algorithm outperforms the other algorithms MMAS, ACS, FFD and Fuzzy ACS compared against it as the number of processors and memory utilization are lesser than these algorithms.

Authors: Alhumyani Hesham 
Published: May 2020

Abstract
This paper presents an efficient image cipher based on applying the chaotic Baker Map (BM) in the Discrete Cosine Transform (DCT). The encryption module of the proposed DCT-based BM image cipher employs a DCT on the original plain-image then, the DCT coefficients of the plain-image are shuffled with the BM. Finally, the inverse DCT is applied to the shuffled plain-image DCT coefficients to obtain the final cipher-image. The decryption module of the proposed DCT-based BM image cipher employs a DCT on the input cipher-image then, the DCT coefficients of the cipher-image are inversely shuffled with the BM. Finally, the inverse DCT is applied to the inversely shuffled cipher-image DCT coefficients to obtain the original plain-image. A set of experimental tests are performed to test the validity of the proposed DCT-based BM image cipher and the performed tests demonstrated the superiority of the proposed DCT-based BM image cipher in terms of statistical, differential, sensitivity and noise immunity.

Abstract
Recently a big interest arises to the automated diagnosis and digitalization of clinical data. The purpose of this article is to present treatment algorithm and software system for Problematic Skin Wounds (PSW) by using Platelet-Rich Plasma (PRP), based on the first study on platelet-rich plasma application carried out in Bulgaria. PSW-PRP-Project software system was developed for entering and processing medical data during PRP treatment, visualization of general patient information, treatment trend, as well as a module for training specialists through the created database. For a period of seven years around 100 patients have been treatment at the Department of Orthopaedics and Traumatology, UMBAL KANEV Ruse AD, by applying platelet-rich plasma. The algorithm for the use of platelet-rich plasma for treating problematic skin wounds allows for the proper and accurate treatment of patients with various problematic skin wounds with the purpose of solving the therapeutic problem and their complete recovery. The procedure’s course is determined based on assessment on three digital criteria TWS, TAS and TSWD. The algorithms are based on our results, obtained for the first in Bulgaria while treating problematic skin wounds by using platelet-rich plasma and successfully treating 92.78% of patients to full recovery.
The EU Regulatory Competition in Asylum Law
Authors: Veshi Denard 
Published: May 2020

Abstract
This paper deals with the principle of subsidiarity in asylum law. It exposes some of the most important ‘push’ factors that have been considered by the European Union (EU) as arguments for the centralisation of asylum law. Through the application of an economic approach, this text examines the need for harmonization of asylum standards to reach the goal established in Article 5 of the Treaty on European Union. An economic methodology is used to investigate the application of the subsidiarity principle by considering some of the most important economic criteria for both centralisation and decentralisation, and by applying the findings to the asylum law. Specifically, this paper considers the Tiebout model, the problem of the ‘race to the bottom’, the reduction of transaction costs, and the importance of the protection of refugee human rights. These theories are commonly used in the cases of a specific issue with a transboundary nature, which produces [negative] international externalities. In addition, they reflect the significance of equal conditions within the EU Member States as well as the role of the EU as a sui generis organisation protecting human rights. It should be noted that this paper does not deal with the basic normative question of whether or not refugees deserve protection, but it aims to expose the advantages and disadvantages of an EU asylum policy. In its conclusion, the paper discusses the advantages of a centralised EU policy that also allows, within certain conditions, some type of competition between the Member States.
Cerebrospinal fluid inflammatory markers in children with aseptic meningitis
Authors: Nadraga Alexander , Khomyn Olena 
Published: May 2020

Abstract
Aseptic meningitis is one of the most common inflammatory disorders of the meninges of the central nervous system (CNS). The aim of our study was to investigate the cytokine profiles in the CSF and in the serum of children with aseptic meningitis to determine their role in CNS inflammation. Sixty-eight (68) children were kept under observation. Cytokine profile of CSF and blood (based on the results of determining of IL-1β, IL-4, IL-10, TNF-α levels) and procalcitonin in children were revealed, meningitis severity were estimated by AMSS score. It was found that in the majority of patients with aseptic meningitis, the levels of IL-1β, TNF-α, IL-10 in CSF were increased and exceeded the serum cytokines levels. The severe course of meningitis was characterized by significantly higher concentrations of IL-1β and TNF-α in CSF, which was confirmed by positive correlation between AMSS score and IL-1β concentration (r=0.46, p<0.01), IL-10 (r=0.32, p<0.01), TNF-α (r=0.62, p<0.05). The IL-10/TNF-α ratio was – 17.8. PCT level in CSF was within normal limits in the majority of patients with meningitis. Increasing of anti-inflammatory cytokine levels in aseptic meningitis contributes to preventing of excessive inflammatory/immune responses in the brain. This can cause a longer diseases course and a longer recovery period. This can an indicate active production of cytokines in the central nervous system due to intrathecal inflammation and activation of immune responses caused by viral infection, but not due to penetration across the blood-brain barrier.
