The Islamic education is a system which tries to implement the noble values of the students which include the aspects of knowledge, self –awareness, and application. Any activities that the teachers do should be able to influence the character of the students as a trigger to shape their personality. The Islamic education, in fact, has set the things relating to how the teachers behave, for instance, how they delivering their learning materials, tolerance, and some related matters. The purpose of this behavior is to shape the students to be a good human either in their society or country.
El fracaso de la fotografía: una respuesta intermedial al programa fenomenológico de camera lucida de Roland Barthes
Authors: Lèal Alfredo 
Published: July 2019

El presente artículo pretende dar cuenta de las limitantes de la propuesta teórica de Roland Barthes para analizar la fotografía en tanto ésta se considere a la luz del programa fenomenológico del filósofo francés. Dada la importancia de la teoría de Barthes en el campo de la fotografía, creemos que dichas limitantes sólo son perceptibles si el programa de Barthes se lee desde una postura intermedial, es decir, desde la relación que la fotografía —en tanto re-presentación material de la realidad— presupone y desarrolla en torno a sí con respecto a instancias histórico-mediáticas que se encuentran en contradicción a las esencias regionales reconocidas por Barthes, tal como lo intentamos hacer en el presente trabajo. De esta forma, la fotografía se presenta como un suplemento que pretende colmar, materialmente, la realidad. Un suplemento que, tanto en su constitución como en sus consecuencias, se basa en un sustrato metafísico, a saber, el aparecimiento absoluto o absoluto aparecimiento del objeto fotografiado.

Abstract
In order to improve the survival rate of probiotics and produce probiotic goat milk from fermented goat milk of Lactobacillus casei L61 by spray drying. Spray drying has been applied to large-scale industrial production of milk powder due to its high efficiency and low cost. However, high temperatures in spray drying can result in the loss of large numbers of probiotic.The purpose of this paper is to study the effects of eight thermal protectants including skim milk, sucrose, glucose, β-cyclodextrin, gelatin, maltodextrin, glycerol, trehalose on the survival rate and viable counts of L.casei L61 after heat treatment by the single factor experiment. All protective agents have a positive effect on increasing the survival rate of L.casei L61 (p<0.05). The results indicated that the survival rates of L.casei L61 were up to the maximum of 10.94%, 1.13%, 3.04%, 0.21%, 6.97%, 0.075, 4.71% and 0.29%, while the additions of skim milk, sucrose, glucose, β-cyclodextrin, gelatin, maltodextrin, glycerol, trehalose were 20mg/L, 10%, 7%, 15%, 1.5%, 3%, 8mL/L, 10%, respectively; the viable counts after heat treatment are 19.69, 0.81, 1.78, 0.455, 12.2, 0.12, 2.75, 0.435(×106CFU/mL), respectively. This paper provides technical a reference for the development of probiotic goat milk powder.

Authors: Jolayemi Olusola Samuel 
Published: July 2019

Abstract
This research demonstrated the significance of variety and thermal holding time (THT) at constant temperature (95 °C) on quality characteristics of mango juice. Eighteen samples from Mado, Julie and Kent mango varieties were produced using full factorial design. Quality parameters, sensory and microbial properties were determined. Variety and THT were significant for most notable variables considered except for some sensory properties. Juice of Julie had the highest vitamin C at 60s, while Mado were superior in virtually all other chemical parameters; having 31.93 – 49.97 µg/100g pro-vitamin A, 51.10 – 113 mg/100g total phenol, 25.60 – 81.40 mg/100g total flavonoid, 1.26 – 1.48 mg/L tannin and 12.60 – 13.60% °Brix. Microbial qualities were influenced by THT; with 60s long enough to achieve stable products. PCA cluster analysis further emphasized variety as the most quality-determining factor in mango juice.

Authors: Obaleye Joshua A. , Abosede Olufunso O. 
Published: July 2019

Abstract
Three manganese complexes of the antibiotic doxycyline viz.: manganese doxycyline, [MnDox2]Cl2‧2H2O (1), and manganese doxycyline with bipyridine, [MnDox2(bpy)]Cl2‧8H2O (2), and phenanthroline, [MnDox2(phen)]Cl2‧8H2O (3), as the ancillary ligand were synthesized and characterized by FT-IR, elemental analysis and electrospray mass spectroscopy. The three complexes show good solubility in DMF and DMSO. Data obtained from spectroscopic techniques used show that doxycycline coordinates to the central manganese atom through the oxygen of the amide group and the carbonyl oxygen atom of ring A while bipyridine/phenanthroline coordinates through the two diimine nitrogen atoms. The stoichiometry of manganese-doxycycline is 1:2 and octahedral geometry is the preferred coordination in all the complexes.

Authors: Gadalińska Elżbieta , Baczmański Andrzej , Wroński Sebastian , Wróbel Mirosław , Scheffzük Christian 
Published: July 2019

Abstract
The paper presents the results of diffraction stress measurement in Al/SiC composite and in 2124T6 aluminum alloy during the in situ tensile test. The main aim of the work is to observe the stress values for different stages of tensile test for the composite after applying two types of thermal treatment and for the alloy used as a matrix in this composite, to identify the type of hardening process. The experimental results were compared against the calculations results obtained from the self-consistent model developed by Baczmański [1] - [3] to gain the information about the micromechanical properties (critical resolved shear stress τcr and hardening parameter H) of the examined materials. This comparison allowed researchers to determine the role of reinforcement in the composite as well as the impact of the heat treatment on the hardening of the material.

Published: July 2019

Abstract
Barely visible impact damage is one of the problems commonly occurring in composite elements during an aircraft operation. The authors described the mechanisms of impact damage formation and propagation in composite structures. The paper presents a performed analysis of an influence of impact parameters on the resulting damage, i.e. its detectability by means of visual observation as well as its extent determined based on ultrasonic tests results. The tests were conducted on the CFRP specimens with a wide range of impact damage cases obtained with combinations of variable impact energy and shapes of impactors. Additionally, an algorithm based on image processing and image analysis methods is proposed for the purpose of the effective evaluation of the ultrasonic data obtained.
Accumulation of Fatigue Microdefects– Entropy Interpretation
Authors: Szafran Krzysztof , Delas Nikolaj 
Published: July 2019

Abstract
The authors of the paper presented some of the models describing the process of micro-cracks’ development. In this study, the process of a selected model of micro-cracking was analyzed. In the model it was assumed that the damage to the material has some “thermodynamic properties” or rather universal properties inherent in most complex systems. In order to calculate the long-term fatigue strength properties of a structure, it is important to have a good understanding of the distribution parameters of the number of defects of different sizes. A model was built using the entropy principle, which is effectively used to test complex systems that are difficult to formalize. As a result of many experimental studies it was found that the development of fatigue damage is closely related to the process of plastic deformation of the material at the contact point of local defects. The results of computer calculations and simulations led to the conclusions presented in the final part of this paper.

Published: July 2019

Abstract
This paper introduces a methodology for one of the challenges regarding cyber-physical systems, ie modelling and control design them as hybrid systems. The proposed methodology comprises modules with specific steps to accomplish the tasks. Specifically, the paper aims to utilize hybrid systems framework onto the chosen hydraulic hybrid system with complex dynamics to showcase different aspects of hybrid systems. The mathematical model was derived using hybrid automata framework and then transformed into the linear form either using Jacobi matrices or using linear approximations without Jacobi matrices. After that the system was validated and analysed and the control design utilizing piecewise linear-quadratic regulator optimal control was proposed. Furthermore, parameters of control algorithm were tuned using particle swarm optimization algorithm. The whole logic, system dynamics and constrains are implemented within MATLAB/Simulink simulation environment using s -functions. The proposed methodology can be implemented on the various types of cyber-physical systems as far as they can be described as hybrid systems.
Metamaterial superstrate microstrip patch antenna for 5G wireless communication based on the theory of characteristic modes
Authors: Hamad Ehab K. I. , Abdelaziz Ahmed 
Published: July 2019

Abstract
Metamaterials (MTMs) have received considerable attention due to their novel electromagnetic properties. Their applications include enhancing gain and bandwidth in microstrip antennas. In this article, a dual band microstrip antenna design based on characteristic mode analysis (CMA) using MTM superstrate is proposed for 5G wireless communication. The CMA is used for the modelling, analysis and optimization of the proposed antenna to examine the underlying modal behaviour of the MTM unit cell and to guide mode excitation. The antenna structure consists of a microstrip feed line connected to a rectangular patch. Then triangular split ring resonator unit cell is inserted on the ground of a traditional patch antenna that resonates at 15 GHz to produce additional resonance at 10 GHz. A planar array of 2 × 3 triangle MTM unit cells is used as superstrate to improve the gain and bandwidth at both resonances simultaneously. The optimal distance between MTM superstrate and the antenna patch is determined using the Fabry-Perot cavity theory to maximize power directivity and efficiency of the proposed antenna. The CST microwave studio software is used to model and optimize the proposed antenna. A prototype of the designed antenna that was fabricated showed good agreement between measurement and simulation results.
Optimization of surface-mounted permanent magnet brushless AC motor using analytical model and differential evolution algorithm
Authors: Mohamed Mohd Rezal , Ishak Dahaman 
Published: July 2019

Abstract
This paper discusses the optimization of surface-mounted permanent magnet brushless AC (PMBLAC) motor using Analytical Sub-domain model with Differential Evolution Algorithm (ASDEA). Only two regions were considered in this analytical sub-domain model, ie magnet and airgap regions, with assistance of Complex Relative Permeance Function (CRPF) to account for the stator slotting effect. Five machine parameters were chosen to be optimized, namely the magnet arc-pole-pitch ratio, slot opening width, magnet thickness, airgap length and stator inner radius. The optimization process has four objectives, ie minimum torque ripple, low cogging torque, high efficiency, and high output torque. The results from the optimized ASDEA were compared with the Analytical Sub-domain Genetic Algorithm (ASGA) and further validated against 2-D finite element model (FEM). Results show a good agreement between analytically optimized models and finite element model. The ASDEA has faster computational time compared to ASGA, and this provides benefit in terms of reducing the machine design parameterization time and less redundancy work required to achieve motor design specifications.

Wireless channel estimation in OFDM systems based on collaborative filtering techniques
Authors: Švedek Velimir , Kurdija Adrian Satja , Ilić Željko 
Published: July 2019

Abstract
In this paper, a new channel estimation algorithm in Orthogonal Frequency Division Multiplexing (OFDM) systems is proposed. The proposed algorithm is suitable for cases with low density of pilot sub-carriers, where standard interpolation methods (linear, second order and cubic spline interpolation) are inaccurate. The algorithm improves the interpolation methods by employing memory based collaborative filtering (CF) techniques which are less sensitive to the number and location of the pilot subcarriers. CF algorithms are usually used in the context of recommender systems (e-commerce) for predictions of the unknown user-item ratings based on known values of similar users. The advantage of CF is the ability to e ciently produce quality predictions with highly sparse data. Computer simulations are used to verify the proposed channel estimation algorithm and demonstrate that the proposed algorithm improves predictive accuracy metrics, such as Root Mean Squared Error (RMSE), compared to usual estimation methods.

Authors: Beresescu Gabriela , Tegla Emanuela , Temistocle Despina , Ormenisan Alina , Baldean Alina 
Published: July 2019

Abstract

Background: Cervical lesions appear on the cervical surface of the lingual or buccal side of the tooth and are classified into carious and non-carious lesions.

Aim: The present study evaluates the performance of three different types of aesthetic restorative materials, used for the restoration of carious or non-carious cervical lesions.

Materials and methods: The study comprised 195 cervical lesions in 45 patients. The restorations were carried out for non-carious cervical lesions in 34.62% of the cases, for primary carious lesions in 40.00% of the cases, and to replace a previous restoration in 25.38% of the cases. The restorations were evaluated at 2 weeks (the reference line), and then at 1 and 2 years after placement. The following have been assessed: restoration retention, color harmonization, surface texture, margin discoloration, anatomical contour, margin integrity, and the presence of secondary caries. The characteristics were registered in conformity with the modified USPHS criteria.

Results: At the one-year evaluation, we noticed the loss of 12 restorations, and after 2 years, the loss of 19 restorations. The results showed significant differences between restorative materials regarding color, margin adaptation, margin coloration, surface texture, as well as criteria regarding the anatomical contour (p <0.05).

Conclusions: The evaluation of the success of restorative material retention must consider the location of the cervical lesion. A successful treatment depends particularly on a full understanding of the factors that caused the lesions and on the method of their treatment.

Published: July 2019

Abstract

Objective: A low level of physical activity is a cardiovascular risk factor. Physical activity patterns may differ among different ethnic groups.

Aim of the study: Our aim was to evaluate the physical activity patterns of two different Roma populations compared to non-Roma.

Material and Methods: The study population included 231 Gabor Roma, 111 Băieși Roma, and 183 non-Roma. A 70-item questionnaire was administered, including also the short form of the International Physical Activity Questionnaire, evaluating daily physical activity in minutes and physical activity categories such as walking, gardening, household activity, and sports. Anthropometric parameters (weight, height, waist and hip circumference) were measured.

Results: The level of physical activity was the lowest among Gabor Roma and was lower in both Roma groups than in non-Roma (Gabor Roma 118.6 ± 91.1 min/day, Băieși Roma 207.55 ± 172.1 min/day, and non-Roma 234.12 ± 167.3 min/day). Both Roma groups had significantly lower percentages of gardening and sport activities compared to non-Roma. Women had a higher level of daily physical activity than men in the Gabor Roma population (144.22 ± 109.4 min/day vs. 79.71 ± 58.2 min/day, p = 0.001). In the two other groups the differences were not statistically significant.

Conclusions: Both Roma groups had significantly lower levels of daily physical activity, with differences between genders. Both Roma groups were lesser engaged in sports and gardening than non-Roma subjects.

We present a new approach based on relieving pressure or friction, strictly based on the results of pedography (pedobarography).
Coronary Shear Stress after Implantation of Bioresorbable Scaffolds – a Modern Interdisciplinary Concept at the Border between Interventional Cardiology and Cardiac Imaging
Authors: Păsăroiu Dan , Parajkó Zsolt , Ferenţ Ionuţ , Opincariu Diana , Benedek Annabell 
Published: July 2019

Abstract
Bioresorbable scaffolds/stents offer new and exciting perspectives in the treatment of patients with acute coronary syndromes, especially after the recent development of invasive imaging techniques, such as optical coherence tomography, which allow complete assessment of vascu-lar segments. A particular advantage of bioresorbable scaffolds is that once the biosorption of the scaffold is complete, the vascular segment regains its normal physiological functions, thus eliminating the risk of late complications. New studies show the importance of shear stress in the progression of vascular atherosclerosis or in accelerating endothelial turnover. Based on the current knowledge in this field, a future standardized determination of shear stress may help in the long-term follow-up of patients that have suffered or are at risk of developing an acute coronary syndrome.
