Biang kehancuran Walid bin alMugirah antara lain: 1. Memiliki aibaib kejiwaan yang dipicu oleh kebenciannya terhadap Islam dan Rasulnya Saw. 2. Tidak tahu seperti apa Allah membagi anugerahNya. Karena tidak tahu, ia melihat dirinya lebih pantas menerima risalah kenabian dari Muhammad 3. Tidak belajar dari sejarah, setiap yang memusuhi nabi pasti hancur. 4. Tidak punya intropeksi diri. Dengan aib yang dibeberkan Alquran sepatutnya dia mengimani Alquran, namun itu pun tidak cukup untuk menyadarkannya. 5. Terfitnah dengan dunia dan isinya. Karena dianugerahi ini dan itu, ia pun merasa punya segalagalanya. 6. Mendustai kata hatinya yang membenarkan Alquran. Untaian katanya yang begitu indah dalam menyifati Alquran bukti nyata dalam hal ini.

Medical experiments on humans are among the most dangerous that a person can be exposed to, especially in light of the tremendous scientific and technological progress that the health field is witnessing, which harms the human right to health safety, the problem of the study stems from the jurisprudential difference about the legality of medical experiments on the human body According to the traditional view, there is no legitimacy for medical experiments when they are stripped of the intention of treatment and cure, and therefore the doctor is asked about errors in the medical experiments that he conducts for the purposes of scientific research, while the modern jurisprudential view legitimizes medical experiments whenever they are for the purposes of healing, treatment and scientific research if they are abstract From the material character, and this requires the approval of rules and regulations for these experiments through the approval of legislation for this type of experiments, similar to many developed countries, such as the French law, and from this problem the objectives of the study are reflected, which is to clarify what is meant by non-therapeutic medical experiments, and to discuss the legitimacy of medical experiments other than Curative treatment on the human body, as well as clarifying the legislative position on non-therapeutic medical experiences on the human body, as well as explaining the responsibility for To violate the rules for conducting these experiments, and to facilitate the achievement of the objectives of the study, its approach is inductive approach based on extrapolating and analyzing texts, in order to reach effective solutions to the study problem.

A two point block backward difference method is established to solve Riccati differential equations directly. Based on a predictor-corrector two point block backward difference method (2PBBD), a code is developed using a set of integration coefficients that eliminates the need to be calculated at every step change. The method requires calculating the integration coefficients only once in the beginning. The 2PBBD has an added advantage of a recurrence relationship between coefficients of different orders which provides a more elegant algorithm. The recurrence relationship between coefficients also reduces the computational cost. � 2016 Author(s).

Affordable and greener materials were extensively studied in electrode fabrication for Liion based batteries but less interest was shown to proton battery. Hence, in this work, a methodology on preparing a natural based binder for proton battery was reported. 2- Hydroxyethyl Cellulose (2HEC) was chosen to replace PVDF commercial binder in electrode for ZnSO4jMnO2 proton battery configuration. SEM image shows good surface formation for both anode and cathode with good porous structure. OCV result shows that the cell improved the stable voltage of reference cell of 0.7 V to 0.9 V after 24 hours. The first discharge of the cell took 6 hours and 49 minutes at 0.005mA and shows good potential for rechargebility test.

There is demand for application of polymer materials in electrochemical devices, especially natural polymers, because of their superiority in mechanical integrity, affordability and biodegradability. In this work, solid biopolymer electrolyte (SBEs) comprising 2-hydroxyethyl cellulose (2-HEC) doped with different weight percentage of ammonium thiocyanate, NH4 SCN (0 – 44 wt.%) were prepared using a facile solution casting technique. The effects of NH4 SCN on ionic conductivity and dielectric properties of SBEs were investigated using electrochemical impedance spectroscopy (EIS). The ionic conductivity recorded at room temperature showed massive improvement for pure 2-HEC from the value of 5.93 x 10-8 S cm-1 to 1.16 ×10-4 S cm-1, comprising 36 wt.% NH4 SCN. Meanwhile, at elevated temperatures, the ionic conductivity revealed the Arrhenius behaviour, where it increased proportional to the temperatures. In addition, by introducing NH4 SCN content as a proton donor, it also effectively reduced the activation energy of the SBEs, which further support enhancing the ionic conductivity. In dielectric permittivity study, the εr and εi increased as the NH4 SCN content increased, revealing the non-Debye dependency of the SBEs, which indicates that the SBEs are ionic conductors. The addition of the optimum value of NH4 SCN content showed good characteristic for electrochemical devices applications.

The surge in global competition necessitates the education system in Malaysia to go through transformation at all aspects, including in the use of technology in Education. The transformation in education towards the 21st Century is not only needed in primary and secondary schools but also in tertiary institutions. The transformation in education leaves a big impact on the field of education, including the teaching of English as Second Language (ESL) which is currently experiencing teaching and learning transformation process as well. This literature review canvasses the advantages of using technology in ESL classroom, the current challenges ESL educators face when teaching ESL in Sabah’s tertiary institutions and the role of ESL educators in using technology in their approach to teaching ESL. This review was carried out through an analysis of secondary data in the form of related and relevant previous studies conducted by researchers in the teaching of English as a second language. The findings indicate that there are some advantages in employing technologies in ESL classrooms. However, there are also few challenges that ESL educators need to embrace or face during teaching ESL in Sabah’s tertiary institutions. ESL educators will serve as a facilitator and guide to assist students in the process of embracing 21st Century learning in Industrial Revolution 4.0 era.

There is a misconception that 21st century education is all about using the right online tools. However, the premise of 21st century education requires the integration of relevant content, skills and instructional support to enhance knowledge processes in line with the requirement of 21st century learning to arrive at meaningful learning experience and not merely the use of online tools. To enhance the integration, an Online Multiliteracies Project Approach (eMULPA) framework is designed by incorporating teachers’ presence, online tools, learning materials, collaborative efforts while fulfilling the syllabus requirement so that the interconnectedness in these elements would give learners a learning experince that is worthwhile and meaningful. The framework which encompases the knowledge processes: exploration, contexualization, investigation, delibration and consolidation is expected to assist learners to have meaningful learning. This paper focuses on the learners’experiences while undergoing the knowledge processes in eMULPA. Data collection tools were interviews, teaching documents and learners’ reflective journals. For this paper, only data from learners’ reflective journal were drawn, coded for themes and explicated because reflective journal is one of the reliable means to gather information on the metacognitive processes undergone by learners. The preliminary findings demonstrated learners’ have undergone meaningful learning experiences through the eMULPA knowledge processes higlighted above. Thus, the implementation of eMULPA is expected to assist learners to acquire the 21st century skills.

Teaching practicum is an essential part of teacher-training that provides real classroom engagement for a beginner teacher. It is considered as one of the most critical components of teacher preparation with the greatest impact on teacher quality (Mtika, 2011; Zeichner, 2010; Graham, 2006; Tang, 2003) and is significant for the development of their pedagogical skills (Kauffman, 1992). The sudden upsurge of the Covid -19 infections around the world in the first quarter of 2020, witnessed massive closure of schools worldwide in order to contain the spread of the pandemic. This unexpected turn of events had flipped the more traditional face-to-face method of teaching and learning into distance learning that requires 21st. Century technology and skills. This paper explores the experience of a group of trainee teachers from an institute of higher learning in Malaysia, at managing this unprecedented challenge in delivering education remotely via technology. Data were collected from interviews and supplemental written records in the form of lesson plans, teaching evidence, and online tools employed for teaching and learning. The findings show that the trainee teachers undergo varied and often challenging experiences in ensuring the continuity of curriculum-based education and the students’ progress in learning. Their successes in delivering the lessons amidst the novel encounters are the epitome of resilient and flexible teachers in the making.

This study proposed a registration framework to fuse 2D echocardiography images of the aortic valve with preoperative cardiac CT volume. The registration facilitates the fusion of CT and echocardiography to aid the diagnosis of aortic valve diseases and provide surgical guidance during transcatheter aortic valve replacement and implantation. The image registration framework consists of two major steps: temporal synchronization and spatial registration. Temporal synchronization allows time stamping of echocardiography time series data to identify frames that are at similar cardiac phase as the CT volume. Spatial registration is an intensity-based normalized mutual information method applied with pattern search optimization algorithm to produce an interpolated cardiac CT image that matches the echocardiography image. Our proposed registration method has been applied on the short-axis “Mercedes Benz” sign view of the aortic valve and long-axis parasternal view of echocardiography images from ten patients. The accuracy of our fully automated registration method was 0.81 ± 0.08 and 1.30 ± 0.13 mm in terms of Dice coefficient and Hausdorff distance for short-axis aortic valve view registration, whereas for long-axis parasternal view registration it was 0.79 ± 0.02 and 1.19 ± 0.11 mm, respectively. This accuracy is comparable to gold standard manual registration by expert. There was no significant difference in aortic annulus diameter measurement between the automatically and manually registered CT images. Without the use of optical tracking, we have shown the applicability of this technique for effective fusion of echocardiography with preoperative CT volume to potentially facilitate catheter-based surgery.

This paper presents the fabrication and characterization of radio frequency (RF) and microwave passive structures on an air substrate using additive manufacturing (3-D printing). The air substrate is realized by 3-D printing RF structures in two separate pieces and snapped together face to face using a LEGO-like process. Spacers printed on the periphery provide the desired air substrate thickness. Metal patterning on nonplanar printed plastic structures is carried out using a damascene-like process. Various RF structures such as low dispersion transmission line, T-line resonator, high-gain patch antenna, slot antenna, and cavity resonator are demonstrated using this process. Good performance is achieved; for example, measured 50-Ω transmission line shows low loss of 0.17 dB/cm at 4 GHz, and a patch antenna (center frequency of 4.5 GHz) shows gain and bandwidth of 7.6 dB and 0.2 GHz, respectively. Details of both measured and simulation results are presented.

In this article, a fully 3-D printed embedded passive harmonic sensor tag with improved read range and better clutter rejection is presented for detecting assets located underground. The sensor tag receives the query signal from a 3-D printed Vivaldi antenna at the fundamental frequency (f 0 ) and radiates back to the interrogator at the second harmonic frequency (2f 0 ). The sensor tag consists of a linearly polarized double slot antenna that operates at both the fundamental as well as the second harmonic frequency. Utilizing the capabilities of 3-D printing, a nonlinear diode is embedded onto the substrate and coupled to the antenna for generating the higher order harmonics is designed. The 3-D printed tag is compatible with direct printing onto the buried assets, such as plastic pipelines, as markers for localization. The polarization of the antenna is used for identifying the location and the direction of the pipeline. The sensor tag has higher signal-to-noise ratio and can be readily interrogated with any hand-held readers from above the ground.

Additive manufacturing, widely known as three-dimensional (3D) printing is a substantial part of in Forth Industrial Revolution (IR 4.0) for the manufacturing ecosystem across a plethora of industrial sectors including electronics, automotive and medical. Within the medical industry, stereolithography (SLA) technique emerges as one of the predominant techniques due to the high-resolution capabilities which is better compared to other additive manufacturing technique. This research aims to utilize blended materials technique in the SLA process with using polyhydroxybutyrate/urethane dimethacrylate (PHB/UDMA) combination to fabricate a new 3D printed materials for medical application in particular arm cast. Viscosity plays a crucial role in the printability of the 3D printed resins. For this research, the maximum viscosity was achieved at approximately 2188 centipoise (cP) with the concentration of PHB at 11% weight ratio. Based on this composition, the tensile and impact strength were able to maintain with a minimal degradation of only 3% relative to the pure UDMA resin which is at 16% in a one month period. The inclusion of PHB is attributed to the structural integrity and stability of the 3D printed materials. Based on the clinical application standards, only 3% by weight composition of PHB failed to meet the requirements for the degree of double bond conversion (DC). These are good indications as most of the composition shows a more complete polymerization process which leads to better performance. For the crystallinity index, the inclusion of PHB contributed towards crystalline structures within UDMA based resin and make the 3D printed PHB/UDMA more prone to fracture, thus in line with the reduction of mechanical performance. Meanwhile, FESEM pictures portrayed two distinct phases region between PHB and UDMA proved the poor interfacial adhesion between the polymer blend. Based on the overall results, 7 wt. % of PHB content was selected as an optimal blending mixture composition for 3D printed arm cast due to better mechanical performance and passed the minimum standard level of DC. This research shows significant contributions in understanding the relationship between printability and mechanical properties of PHB/UDMA resins in particular for 3D printed arm cast using SLA technique.
