Thermal Stress Flow Analysis in Fabrication of Acetabular Shells Using SLM
Authors: Khorasani Amir Mahyar , Gibson Ian , Goldberg Moshe , Masoud Movahedi Mohammad , Littlefair Guy 
Published: February 2017

<p>Additive Manufacturing (AM), more popularly known as 3D Printing, is a process for producing functional artifacts by adding layers of materials from data generated directly from 3D solid CAD models. Additive Manufacturing (AM) is the formalized term for what used to be called Rapid Prototyping and what is commonly referred to as 3D Printing. The key to how AM works is that parts are made by adding layers of material; each layer corresponding to a thin cross-section of the part derived from the original CAD data. Although most AM machines produce parts using polymers, there are an increasing number of machines that can directly fabricate in metals. The majority of these machines fabricate from raw material in powder form using a directed energy beam to create a local melt zone. Total hip replacement is recommended for people who have medical issues related to excessive wear of the acetabular, osteoarthritis, accident or age. Researches have shown that large numbers of hip arthroplasties (where the articular surface of a musculoskeletal joint is replaced), hip remodelling, or realignment are carried out annually and will increase in the next few decades. Manufacturing of acetabular shells by using AM is a promising and emerging method that has a great potential to improve public health. Lost wax casting or investment casting is currently used to produce acetabular shells followed by lengthy and complex secondary processes such as machining and polishing. Living organs and medical models have intricate 3D shapes that are challenging to identity in X-ray CT images. These images are used for preparing treatment plans to improve the quality of the surgeries regarding waiting and surgery time per procedure and care regime. For instance, a limited number of hip replacement procedures can be carried out on each acetabulum due to a decrease of bone thickness. Rapid prototyping is a suitable treatment planning tool in complex cases to enhance the quality of surgical procedure and provide long-term stability that can be used to customize the shape and size of the acetabular shell. In this paper, to analyse the manufacturing of a prosthetic acetabular shell, built-up lines resulting from a thermal stress flow and process stopping during the selective laser melting (SLM) AM process, with regarding Gibbs free energy, interfacial energy, and equilibrium temperature will be discussed. Geometrical measurements showed 1.59% and 0.27% differences between the designed and manufactured prototype for inside and outside diameter respectively. Experimental results showed that thermal stress flow in outer surfaces are compressive, but for inner surfaces are tensile, so built-up lines in inner and outer surfaces appear as a groove and dent respectively. The results also indicate that SLM is an accurate and promising method for fabrication of acetabular cup.</p>
Whose Job is it? 3D Scanning Design for Innovation
Authors: Little Chris , Loy Jennifer 
Published: February 2017

<p>There are often references in design education to the idea that design graduates of the future will be working in jobs that do not yet exist. There are therefore opportunities emerging that are not currently recognised as within the designers’ purview. One such area of growth is emerging out around the potentials created by technological developments relating to 3D scanning. This technology is proving to be a catalyst for not only new product outcomes but also innovations in thinking and practice. This is particularly in relation to new workflows that are permeating traditional discipline boundaries. The wide range of advances in digital scanning over the last twenty years have resulted in a myriad of complex capabilities, and the potential of these technologies to support innovation in practice, outcome and thinking are only beginning to be explored. Examples of these explorations are considered in this paper, demonstrating how they can provide a basis for redirecting design for a future of digital immersion. This paper questions the rigour in current approaches to teaching 3D scanning technologies in design education. It provides an argument that 3D scanning is part of a rapidly evolving suite of digital enablers that are challenging conventional design practice and suggests that educators need to more effectively research and understand the innovations that 3D scanning technologies can inspire. </p>
Professor Gender, Age, and “Hotness” in Influencing College Students’ Generation and Interpretation of Professor Ratings
Authors: Sohr-Preston Sara L. , Boswell Stefanie S. , McCaleb Kayla , Robertson Deanna 
Published: February 2017

<p>Undergraduate psychology students rated expectations of a bogus professor (randomly designated a man or woman and hot versus not hot) based on an online rating and sample comments as found on RateMyProfessors.com (RMP). Five professor qualities were derived using principal components analysis (PCA): dedication, attractiveness, enhancement, fairness, and clarity. Participants rated current psychology professors on the same qualities. Current professors were divided based on gender (man or woman), age (under 35 or 35 and older), and attractiveness (at or below the median or above the median). Using multivariate analysis of covariance (MANCOVA), students expected hot professors to be more attractive but lower in clarity. They rated current professors as lowest in clarity when a man and 35 or older. Current professors were rated significantly lower in dedication, enhancement, fairness, and clarity when rated at or below the median on attractiveness. Results, with previous research, suggest numerous factors, largely out of professors’ control, influencing how students interpret and create professor ratings. Caution is therefore warranted in using online ratings to select courses or make hiring and promotion decisions. </p>
A Literary Approach to teaching English Language in a Multi – Cultural Class - Room
Authors: Choudhary Sanju 
Published: February 2017

<p>Literature is not generally considered as a coherent branch of the curriculum in relation to language – development in either mother tongue or foreign language – teaching. As teachers of English in Multi cultural Indian class rooms we come across students with varying degree of competence in English language learning. Though, language learning is a natural process for natives but the Students of other languages put in colossal efforts to learn it. Despite their sincere efforts they face challenges regarding Pronunciation, Spelling and Vocabulary. The Indian class rooms are a microcosm of the larger society, so teaching English language in a manner which equips the students to face the cut-throat competition has become a necessity and a challenge for English language Teachers. English today has become the key determinant for getting success in their career. The hackneyed and stereotypical methods of teaching are not acceptable now. Teachers have no longer remained arbitrary dispensers of knowledge but they are playing the role of a guide and facilitator for the students. Teachers of English are using innovative ideas to make English language teaching and learning interesting and simple. Teachers have started using the literary texts and their analysis to explore and ignite the imagination and creative skills of the students. One needs to think and rethink the contribution of literature to intelligent thinking as well as its role in the process of teaching – learning. My paper would, therefore, be an attempt at exploring the nature of the literary experience in the present day class rooms; and the broader role of literature in life.</p>
The role of information literacy competence and higher order thinking skills to develop academic writing in Science and Engineering learners
Authors: Kumari B. Kranthi 
Published: February 2017

<p>The English syllabus for learners pursuing engineering courses includes teaching writing as one of the objectives. Learners who enroll for these courses are not equipped with the general writing skills that they should have mastered at the entry level. In this context, a study was organized to develop academic writing skills of the undergraduate learners who are pursuing engineering courses. The study focused on raising awareness in the learners of the nature and characteristics of academic texts in order to develop academic writing skills. The study also emphasizes that involving the learners in the cognitive processes of writing that include defining the rhetorical problem, identifying the rhetorical situation, the audience and setting goals for writing, planning for the text by generating and organizing ideas is necessary. The study further suggests that discussions between learners and teachers regarding the construction of a text and the way language works in various text types facilitates better writing.</p>
Empowering Engineering Students through Employability Skills

Published: February 2017

<p>A professional course like engineering strives to get maximum number of its students placed through campus interviews. While communication skills have been added in all the engineering courses with the aim to improve their performance in placement, the syllabus mostly concentrates on the development of four language skills. The students are not made aware of the employability skills and their significance. the increasing competition makes it imperative that apart from a regular degree certain skills are required by engineers. Industries while advertising for various posts even mention essential skills required along with the essential qualification. However skills and the significance of skills while applying for jobs or while facing interviews is a topic which is rarely given consideration while preparing for job interviews or while entering the job market. This paper intends to enlist the importance of skills and why students need to be aware of the skills they possess and how they can work on packaging their candidature around a few skills. Different profession requires different skills and if students identify their skills or acquire certain skills they can unquestionably have an added advantage in the interview and placement. Hence, this paper intends to enlist the skills, the importance of skills, ways to create awareness of individual skills specifically in engineering students who will step into the industry in near future.</p>

<p>Promoter in transgene construct plays an important role on regulating of transgene expression level in transgenic fish. In fish transgenesis, researcher convinced that use all-fish gene construct is safety and prospective. This study was performed to compare effectiveness b-actin promoter, - the promoter which has ubiquitous, constitutive, housekeeping characteristics, from common carp (homologous) and from tilapia and medaka b-actin promoters (heterologous) in driving of green fluorescent protein (GFP) expression as a model of target gene on common carp<em> </em>transgenesis. These gene constructs were separately microinjected into cytoplasm of 60 one-cell-stage common carp embryos. The results suggested that 70% survival rate at embryo stage and 45% hatching rate values showed that the microinjection was performed successfully. Percentage of embryos expressing GFP gene were slightly higher when injected using common carp and medaka promoters than those of using tilapia promoter. Percentage of larvae expressing GFP using common carp promoter was similar with medaka promoter. Furthermore, GFP expression using common carp b-actin promoter could be detected at one-week-old larvae, while GFP expressing using medaka b-actin promoter was lasted at 2-day-old larvae. The results demonstrated that homologous promoter more effective in driving of a target gene expression than that of heterologous promoter. </p> <p>Key words: homologous promoter, GFP, transgenesis, common carp</p> <p> </p> <p>ABSTRAK</p> <p>Promoter dalam konstruksi transgen berperan penting dalam pengaturan tingkat ekspresi transgen pada ikan transgenik.

<p>This study aimed to produce recombinant growth hormone <em>(r</em>GH) protein of common carp (<em>Cyprinus carpio</em>) and evaluate its bioactivity. DNA fragment encoding mature GH protein of common carp (<em>mCc</em>GH) was amplified by polymerase chain reaction (PCR) method and PCR products were then ligated into pCold I to generate pCold I-<em>mCc</em>GH protein expression vector. <em>Escherichia coli </em>BL21 (DE3) harboring pCold I-<em>mCc</em>GH was cultured in the 2xYT medium at 15 °C for 24 hours and protein production was induced by isopropyl-beta-thio galactopyranoside (IPTG). The inclusion bodies containing rGH protein from <em>E. coli </em>transformants were isolated by sonication method and analyzed by SDS-PAGE. The result showed that rGH with molecular weight of about 25 kDa was obtained. Common carp juveniles with average body weight of 5.2±0.4 g were intramuscularly injected once a week for 4 weeks with rGH protein solution from 1 μg bacterial cells per gram fish body weight. The result showed that juveniles fish injected with rGH grew 106.56% higher than control.
