An overview of the challenges of transnationalising a threshold concepts course

There are significant challenges in transnationalising a semester mode course to a block mode course. This is complicated further by the nature of the course, in being one that seeks to develop threshold knowledge in the form of a high level conceptual view that is quite unfamiliar to many students. The time compression of a 13 week project based course with supporting lectures, workshops, tutorials to a five day intensive lecturer contact activities and four week post-course project makes it difficult to balance the needs of the many stakeholders involved yet still deliver effective outcomes. This paper provides an overview of the challenges and describes the approach used to address these challenges. It identifies the needs of the various stakeholders, from teachers, learners, universities and professional bodies, and discusses how the conflicting needs can be managed and problems mitigated. The final section evaluates the success of the approach and identifies further areas for further improvement.
Effect of anuloma and viloma pranayama on stress of nurses

Background: Nurses are an integral component of the health care delivery system. Nurses encounter a variety of stressors while discharging their duties. Mind-body interventions are beneficial in stressrelated mental and physical disorders. Yogic breathing is a unique method for influencing psychological and stress-related disorders. Aim: To evaluate the effect of Anuloma and Viloma Pranayama on stress among nurses. Method and Materials: A pre experimental one group pretest posttest design was adopted for study. 296 female nurses were selected using nonprobability purposive sampling technique. Modified Expanded Nursing Stress Scale (ENSS) was used to measure the stress of clinical nurses. The pre test stress level was evaluated on the day 1 and then the CD of video-assisted intervention on anuloma and viloma pranayama was distributed among participants and were instructed to perform anuloma and viloma pranayama for six months and post test stress level was evaluated on day 180. Result: Result revealed that major nursing stress factors causing stress to the participants were economical and professional growth stressors, direct patient care, patient and family stressors and workload stressors, caused significantly higher stress among participants. Overall mean pre-test stress value was 106.12 ± 26.34, while the mean post-test stress value was 70.48 ± 15.18. After the intervention, a statistically significant decrease in the stress level was seen in nurses and the difference was found to be statistically significant (P<0.05). Conclusion: The video-assisted intervention of anuloma and viloma pranayama used in this study was effective in reducing stress of clinical nurses.
Parameter estimation of the arterial system

PARAMETER ESTIMATION OF THE ARTERIAL SYSTEM James Charles Carter II Old Dominion University, 2008 Director: Dr. Ayodeji O. Demuren There are a number of disorders that originate from or involve faulty operation of the cardiovascular system. Diseases such as atherosclerosis, diabetes and hypertension can have a debilitating effect on blood flow. This makes the tools for simulating the effects of such diseases on blood flow important. Measures, such as pulse wave velocity, that are generated by models of the cardiovascular system can be important indicators of cardiac health. Although physically measurable, obtaining some parameters comes with a high cost and discomfort to the patient. Models can provide an assessment of many important parameters. The purpose of this project was to create a robust computer generated model of the arterial system. This model is a one-dimensional/Womersley model that used transmission line hemodynamic theory to calculate the blood pressure waveforms and then the Womersley theory to calculate the flow velocity in various areas of the human body. The accuracy of the model was tested using data from eight subjects. The model provided realistic and individualized cardiovascular parameters without requiring any major adjustment to the internal algorithms.
PENERIMAAN DOSIS ORGAN KRITIS PADA PEMERIKSAAN CEREBRAL DSA DENGAN BIPLANE C-Arm

Background:Cerebral Digital Substraction Angiography (DSA) screening is widely used in hospitals to find out even treat strokes and vascular abnormalities. During the examination, the patient received radiation from a C-Arm Biplane. The estimated dose received by the patient has been measured on the monitor screen which is the DAP value, but to find out the actual dose received by the patient, it is necessary to measure directly using the TLD attached to the patient's body during the examination. Method: Measurement of critical organ dose is done by attaching TLD-100 chips on the surface of the eye, thyroid, and gonad to 6 different patients. Results: The purpose of this study was to measure and evaluate the amount of dose received by the patient's critical organs during Cerebral DSA examination. Conclusion: The results showed that (1) the amount of eye dose received by the patient during cerebral DSA examination was 23.01 mGy to 144,787 mGy. (2) the amount of thyroid dose received by the patient during cerebral DSA examination is 15,348 mGy to 76,162 mGy. (3) the amount of gonad dose received by the patient during Cerebral DSA examination is 0.09 mGy to 229,848 mGy. (4) DAP values during Cerebral DSA examination obtained values in the range of 77088 mGycm2 to 167718 mGycm2.
Mechanical Aspects of Nonhomogeneous Deformation of Aluminum Single Crystals under Compression along [100] and [110] Directions

The deformation behavior of aluminum single crystals subjected to compression along the [100] and [110] directions is numerically examined in terms of crystal plasticity. A constitutive model taking into account slip geometry in face-centered cubic crystals is developed using experimental data for the single-crystal samples with lateral sides coplanar to certain crystal planes. Two sets of calculations are performed using ABAQUS/Explicit to examine the features of plastic strain evolution in perfectly plastic and strain-hardened crystals. Special attention is given to the discussion of mechanical aspects of crystal fragmentation. Several distinct deformation stages are revealed in the calculations. In the first stage, narrow solitary fronts of plastic deformation are alternately formed near the top or bottom surfaces and then propagate towards opposite ends to save the symmetry of the crystal shape. The strain rate within the fronts is an order of magnitude higher than the average strain rate. The first stage lasts longer in the strain-hardened crystals, eventually giving way to an intermediate stage of multiple slips in different crystal parts. Finally, the crystal shape becomes asymmetrical, but no pronounced macroscopic strain localization has been revealed at any deformation stage. The second stage in perfectly plastic crystals relates to abrupt strain localization within a through-thickness band-shaped region, accompanied by macroscale crystal fragmentation. Stress analysis has shown that pure compression took place only in the first deformation stage. Once the crystal shape has lost its symmetry, the compressive stress in some regions progressively decreases to zero and eventually turns tensile.
Pennies from Haven: Wages and Profit Shifting

Increasing attention has been given to the fact that some multinational enterprises shift income to tax haven countries, an activity that generates inequality in corporate taxation. Here, we examine how profit shifting relates to wage inequality. Using rich matched employer-employee data from Norway, we find that profit-shifting firms pay higher wages, particularly among service firms where the wage premium is approximately 2%. Furthermore, this average effect masks significant within-firm heterogeneity with high-skill occupations – and managers in particular – earning higher shifting wage premiums. CEOs particularly gain, with their wages rising nearly 10%. These results thus suggest that profit shifting by multinationals meaningfully contributes to wage inequality, both between and within firms. Finally, our back-of-the-envelope calculations suggest these higher wages would generate additional income tax revenues which would offset around 3% of the fall in Norway’s corporate tax revenues due to profit shifting.

PERENCANAAN PERBAIKAN TANAH DASAR DAN ANALISA STABILITAS TANGGUL PADA AREA REKLAMASI PROYEK PENGEMBANGAN PELABUHAN PETI KEMAS BELAWAN, MEDAN (TAHAP II)

Perluasan Pelabuhan Peti Kemas Belawan dilaksanakan karena jumlah kargo yang terus meningkat setiap tahunnya. Oleh karena itu dilaksanakan proyek pengembangan bertahap untuk meningkatkan kapasitas pelabuhan Belawan. Peningkatan kapasitas dimulai dengan perluasan lapangan penumpukan. Lebar perluasan berupa area reklamasi sepanjang 400 m dan lebar 405 m pada pengembangan tahap II. Dari hasil penyelidikan tanah (geotechnical survey) yang dilakukan oleh PT. Pelabuhan Indonesia I pada tahun 2009 didapatkan hasil bahwa tanah dasar pada area reklamasi tersebut merupakan tanah lempung yang cenderung lunak. Maka akan sulit untuk melaksanakan reklamasi karena rendahnya daya dukung tanah dasar dan besarnya pemampatan yang mungkin terjadi. Sehingga diperlukan perbaikan tanah dasar dan percepatan waktu konsolidasi. Selain itu diperlukan struktur pelindung berupa tanggul untuk melindungi timbunan dari terjangan arus dan gelombang air laut. Perbaikan tanah dasar dalam Tugas Akhir ini dilakukan dengan metode preloading sistem surcharge. Sedangkan percepatan waktu pemampatan konsolidasi digunakan prefabricated vertical drain (PVD). Selain itu dalam Tugas akhir ini juga direncanakan turap baja dan perkuatan tanggul dengan menggunakan geotextile untuk meningkatkan daya dukung tanah dasar di bawah tanggul. Dari analisa data tanah, disimpulkan bahwa tanah pada reklamasi harus dibagi dalam tiga zona. Zona 1 yang diwakili oleh BH-1, Zona 2 oleh BH-2 dan Zona 3 oleh BH-3. Dengan elevasi timbunan final setinggi +3,5 m LWS, diperoleh elevasi Hinisial untuk Zona 1 sebesar +16 m LWS, Zona 2 sebesar +21,1 m LWS dan Zona 3 sebesar +21,1 m LWS. Hinisial tersebut sudah termasuk timbunan surcharge yang akan dibongkar sebesar 5,5 m. Penimbunan diakukan secara bertahap dengan kecepatan 50 cm/ minggu. Untuk perkuatan tanah timbunan digunakan geotextile pada Zona 1, Zona 2 dan Zona 3 masing-masing sebanyak 34 lapis, 53 lapis dan 42 lapis. PVD pola segitiga pada Zona 1 dipasang dengan jarak 1,75 m, sedangkan pada Zona 2 dan Zona 3 dipasang dengan jarak 1,5 m. Untuk perkuatan lereng digunakan sheetpile baja dengan dua alternatif yaitu dengan angker dan tanpa angker. Turap baja dengan angker dipancang sedalam 9,5 m, dengan panjang angker 17,75 m berdiameter 10 cm. Angker dipasang setiap 3 m dengan dimensi blok angker 1,5 m x 2,65 m. Turap baja tanpa angker dipancang sedalam 13 m.
SEEING AMONG FOLIAGE WITH LIDAR AND MACHINE LEARNING: TOWARDS A TRANSFERABLE ARCHAEOLOGICAL PIPELINE

Abstract. Airborne LiDAR technology has become an essential tool in archaeology during the last two decades since it allows archaeologists to measure and map items or structures that would otherwise be hidden under vegetation. In order to detect and characterise the archaeological evidence, it is a common practice to extract accurate digital terrain models (DTM) by filtering out the vegetation from Airborne Laser Scanning (ALS) datasets. Although previous approaches have performed well in ALS filtration, they are still subject to several variables (flight height, forest cover, type of sensors utilised, etc.) and are frequently integrated into expensive commercial software or customised for specific locations. This study presents a workflow for treating ALS archaeological datasets using machine learning algorithms for both filtering the vegetation and detecting hidden structures. The workflow is applied to two different archaeological environments (in terms of structures, vegetation, landscape, point density), and results demonstrate that the pipeline is rapid and accurate, and the prediction model is transferable.
Sensory material architectures: Concepts and methodologies for spatial tectonics and tactile responsivity in knitted textile hybrid structures

As the knowledge of material computation advances, continuing the seamless integration of design and fabrication, questions beyond materialization can be addressed with a focus on sensing, feedback, and engagement as critical factors of design exploration. This article will discuss a series of prototypes, design methodologies, and technologies that articulate a textile’s micro-architecture, at the scale of fibers and stitches, to instrumentalize simultaneous structural, spatial, and sensory-responsive qualities. The progression of research displays an ever-deepening instrumentalization of fiber structure and its implications to form definition and responsivity, in creating form- and bending-active structures. The research results in a more refined definition of material behavior as the innate phenomena which emerge at the moment of textile fabrication. Ultimately, the architecture, in its materiality and physical, visual, and auditory responsivity, is designed to address specific challenges for children in filtering multiple sensory inputs, an underlying factor of autism spectrum disorder.
Hybrid Multivector FCS–MPC for Six-Phase Electric Drives

Standard finite control set model predictive controllers (FCS–MPC) suffer from a deteriorated current quality when applied to multiphase drives. This problem has been recently mitigated with the concept of virtual voltage vectors. Its application ensures reduced current harmonics by limiting the x–y voltage injection. An intensive research effort has been done seeking for the best vector combination to provide an optimized performance in FCS–MPC. On one hand, multivector strategies including a null vector refine the effective voltage production with enhanced current quality but the dc-link utilization decreases. On the other hand, the exclusive use of large virtual vectors (LVVs) ensures a higher dc-link utilization at the price of a poorer current quality at low-voltage operation. This article first proposes an extended version of multivector strategies using a zero vector by including a quartet of voltage vectors. The usage of five switching states into the predictive approach (MV5–MPC) improves the current quality but still lacks a suitable utilization of the dc-link voltage. To overcome this limitation, the proposed MV5–MPC is combined with LVV–MPC to provide a hybrid solution that simultaneously achieves a higher current quality and a satisfactory dc-link utilization. Experimental results confirm the effectiveness of the proposal.
Causes and Consequences of Nuclear Envelope Rupture and DNA Damage in Micronuclei

Micronuclei are small, aberrant nuclear compartments containing mis-segregated chromosomes or chromosomal fragments. During telophase, dysfunctional micronuclear envelope reassembly leaves the micronuclear envelope highly unstable and rupture-prone. Following rupture, micronuclei attempt to repair membrane gaps, but the process is typically unsuccessful and may promote the invasion of ER tubules into the interior of micronuclei. These abnormalities cause ruptured micronuclei to accumulate significant DNA damage in the form of both single-stranded DNA and double-stranded breaks. Because micronuclei are capable of promoting genome instability, it is essential to understand the sources of DNA damage and the mechanism through which it arises in these structures. In this review, I will explore the causes and consequences of micronuclear envelope rupture, beginning with the processes surrounding improper micronuclear envelope reassembly. I will then discuss micronuclear envelope rupture, attempted micronuclear envelope repair and its consequences, and the proposed causes of micronuclear DNA damage.
Multiple Gastric Metastases after Distal Pancreatectomy for Pancreatic Cancer

A 67-year-old woman underwent distal pancreatectomy for pancreatic cancer. Recurrence in the form of lung metastasis was discovered eight months after surgery, and chemotherapy was initiated. Two years after the surgery, she was admitted for the evaluation of melena. Esophagogastroduodenoscopy revealed multiple subepithelial lesions with ulceration from the gastric body to the fornix. The histopathology of biopsy specimens was consistent with ductal adenocarcinoma, which appeared similar to the resected pancreatic cancer. The patient was diagnosed with multiple gastric metastases of pancreatic cancer. We herein report a case of pancreatic cancer with multiple gastric metastases that occurred after surgery for pancreatic tail cancer.

Downsizing Effects on Micro and Nano Comb Drives

Downscaling has been a focal task of Electronics and Electromechanics in the last few decades, and a great engine for technological progress as well. Nevertheless, a scaling operation affects device physics, functioning and performance. The present paper investigates about the impact of scaling on a test case compliant electrostatic micro or nano actuator that is under development with two preferred micro fabrication methods, namely, thick SOI and thin amorphous silicon. A series of numerical trials on materials strength, electro-mechanical characteristics, sensitivity and overall actuation performance have been carried out at different grades of down-scaling and of aspect ratio. This gave rise to new design charts that we propose here as a predictive and friendly guide to select the most appropriate micro fabrication method.
Socially-Aware Energy-Efficient Task Partial Offloading in MEC Networks With D2D Collaboration

The future wireless network will face demands of massive connectivity and intensive computation with the increase of mobile devices. Mobile edge computing (MEC) and Device-to-Device (D2D) have emerged as promising technologies to address the above challenges, and implementing social relationships in D2D-MEC networks can improve the reliability of D2D links. Exploiting these benefits, we investigate the energy-efficient task offloading problem in socially-aware D2D-assisted MEC networks, where the user devices can offload tasks to the nearby device or further forward to the MEC server based on social relationships. Specifically, we design a task partial offloading scheme of joint D2D connection selection, transmit power control and task allocation, to maximize the long-term network utility with considering dynamic system status and random task arrival. First, the social relationship among users is quantified into a social trust matrix. As the formulated socially-aware energy-efficient problem is a long-term stochastic optimization problem that is directly intractable, we thus employ the Lyapunov optimization to transform it into a series of short-term problems, each of which can be solved by the Karush-Kuhn-Tucker method and a pricing-based matching algorithm. Finally, we verify the performance optimality and the long-term network stability through numerical simulations as well as theoretical analysis.
Synthèse de filtres de diagnostic pour les systèmes modélisés sous forme LPV polytopique

The work presented in this article is focussed on the design of robust Fault Detection and Isolation (FDI) filters for the class of LPV (Linear Parameter Varying) systems. A sufficient condition is established to guarantee sensitivity performances of the residual signal vector to faults. Robustness constraints against model perturbations and disturbances are also taken into account in the design method. The synthesis problem is formulated in terms of a convex optimization problem which is solved using LMI (Linear Matrix Inequalities) techniques. The proposed method is applied to the secondary circuit of a Nuclear Power Plant.
Endoluminal Functional Lumen Imaging Probe Is Safe in Children Under Five Years Old

ABSTRACT Background: Endoluminal functional lumen imaging probe (EndoFLIP) is a minimally invasive, novel device that uses high-resolution impedance planimetry to measure important parameters of the gastrointestinal lumen that aid in the diagnosis of esophageal disorders. EndoFLiP is approved by the US Food and Drug Administration (FDA) for children 5 years and older. We sought to compare its safety and luminal characteristics between children under 5 years of age with children 5 years and older. Methods: A single-center retrospective review was performed to identify all patients < 21 years of age who underwent esophagogastroduodenoscopy (EGD) with EndoFLIP between October 2017 and November 2020. Results: Sixty-seven EGDs with EndoFLIP were performed in 56 patients, including 14 that were done in children < 5 years and 53 in children ≥5years. The median age in the < 5-year group was 1.7years (interquartile range [IQR], 0.9–4.4) and the youngest patient was 1 month old. The median age in ≥5-year group was 14.3 years (IQR, 8.2–16.2). Median procedure times were similar (32 minutes [IQR, 25–48] for the < 5-year group; 28 minutes [IQR, 20–33] for ≥5-year group; P = 0.08). There were no adverse events or unplanned hospitalizations in either group. At 30 mL inflation, the pressure of the lower esophageal sphincter (LES) was statistically different between the 2 groups (P = 0.02). Conclusion: EndoFLIP appears to be safe for use in our small cohort of children < 5 years of age and may be an important tool in the management of esophageal disorders in this age group. There was no difference in procedure time between our 2 age groups and there were no procedure-related complications.
Feature Selection using PMOGA for Microarray Datasets

: Microarray technology is significantly impacting the community to know the primary characteristic underlining the expansion and growth of genes. Regardless of its many helpful relevance in analysis of drug detection and disease diagnosis; microarray data has turned into a dispute for various bio-analysts. The dimensionality problem in Microarrays leads to expansion of some new methods. The dilemma of dimensionality reduction in terms of features has been taken as a multi-objective optimization problem, thus, can be solved by using some multi-objective optimization techniques. Yet reduction in features takes a lot of time for final submission, therefore, parallel genetic algorithms will do this task in a more efficient way by parallel optimization of multiple distinct parts of a dataset. In this paper, we have designed a new combined method for parallel implementation of gene selection in multi-objective perspective named as PMOGA. Individual migration strategy is followed to improve the parallel searching speed for improving the efficiency of the proposed algorithm. A comparative study of the proposed PMOGA has been done on eight most referenced datasets. The obtained results confirm the supremacy of MOGA based parallel approach over the other approaches based on different performance measures.
