Automated detection of slum area change in Hyderabad, India using multitemporal satellite imagery
No full textThis paper presents an approach to automated identification of slum area change patterns in Hyderabad, India, using multi-year and multi-sensor very high resolution satellite imagery. It relies upon a lacunarity-based slum detection algorithm, combined with Canny- and LSD-based imagery pre-processing routines. This method outputs plausible and spatially explicit slum locations for the whole urban agglomeration of Hyderabad in years 2003 and 2010. The results indicate a considerable growth of area occupied by slums between these years and allow identification of trends in slum development in this urban agglomeration
Design of Midway Energy (Middleware System) as part of Illuminator: Energy System Integration Development Tool Kit
No full textUsing the energy system is part of our daily routine but the complexity of power systems and its understanding have both been confined to the experts in the field. Furthermore, the advent of the Information and Communication Technology (ICT) and the Internet of Things (IoT), power system integration is becoming even more complex for the system planners and operators. Various clean energy technologies like solar power, massive offshore wind, Electric vehicle as well as the increasing dependency of the Prosumers to move towards a future decentralized and transactive energy market. There is hence a need to educate the general public about the important problems encountered during the energy transition as well as to provide a demystifying version of the existing power system to exhibit its complexity and its benefits of intelligent multi-energy systems.Energy System Integration Development (ESID) kit could solve this issue.This project concerns the design and development of a Middleware software system based IOT application, which runs on Raspberry PIs (RasPi), contribute to the layered bottom-top approach of the Illuminator - Energy System Integration Development Tool Kit and has the main goal to help in assisting the application layer to simulate energy system integration scenarios and will be prototyping simple proofs-of-concept for validation purpose. It’s realized as part of the master thesis curriculum of the author. On the completion of this project, there will be a generic middleware system that can be used by the end users/application layer to demonstrate energy system integration scenarios, which is scalable, reconfigurable, inter portable.Illuminator - Energy System Integration Development Tool Kit aimed to become an open-source platform depicting energy integration problems, an education tool kit, and research to prototype control algorithms for counteracting the energy transition challenges. The general public and system integrators would benefit as well as the stakeholders as it can help them analyze the energy integration challenges in a user-centric fashion.viiIEPG | IlluminatorElectrical Engineering | Electrical Power Engineerin

Academic authorship: who, why and in what order?
No full textWe are frequently asked by our colleagues and students for advice on authorship for scientific articles. This short paper outlines some of the issues that we have experienced and the advice we usually provide. This editorial follows on from our work on submitting a paper1 and also on writing an academic paper for publication.2 We should like to start by noting that, in our view, there exist two separate, but related issues: (a) authorship and (b) order of authors. The issue of authorship centres on the notion of who can be an author, who should be an author and who definitely should not be an author, and this is partly discipline specific. The second issue, the order of authors, is usually dictated by the academic tradition from which the work comes. One can immediately envisage disagreements within a multi-disciplinary team of researchers where members of the team may have different approaches to authorship order

Infection control management of patients with suspected highly infectious diseases in emergency departments: data from a survey in 41 facilities in 14 European countries
No full textBackground: In Emergency and Medical Admission Departments (EDs and MADs), prompt recognition and appropriate infection control management of patients with Highly Infectious Diseases (HIDs, e.g. Viral Hemorrhagic Fevers and SARS) are fundamental for avoiding nosocomial outbreaks.
Methods: The EuroNHID (European Network for Highly Infectious Diseases) project collected data from 41 EDs and MADs in 14 European countries, located in the same facility as a national/regional referral centre for HIDs, using specifically developed checklists, during on-site visits from February to November 2009.
Results: Isolation rooms were available in 34 facilities (82,9%): these rooms had anteroom in 19, dedicated entrance in 15, negative pressure in 17, and HEPA filtration of exhausting air in 12. Only 6 centres (14,6%) had isolation rooms with all characteristics. Personnel trained for the recognition of HIDs was available in 24 facilities; management protocols for HIDs were available in 35.
Conclusions: Preparedness level for the safe and appropriate management of HIDs is partially adequate in the surveyed EDs and MADs
Effects of using multi-vide ruler kit in the acquisition of numeracy skills among PROTIM students
No full textOne effective way to teach arithmetic more interestingly and make it easier to learn is through the use of instructional materials. These can help students master certain mathematical skills, particularly multiplication and division, often considered difficult amongst primary school pupils. Nevertheless, the insufficiency of appropriate instructional materials causes difficulty in understanding how to use the proper technique or apply the concept, especially in multiplication. With this in mind, this study investigated whether the innovative and creative instructional material designed to assist and enhance numeracy skills, namely the Multi-vide Ruler kit, could increase students' ability in solving multiplication and division questions and whether it affected their interest in solving numeracy problems. Participants in this study included ten PROTIM (Program Tiga M [Three M Program] - membaca [reading], menulis [writing] dan mengira [calculate]) students, 9-10 years old, who had difficulties in reading, writing and arithmetic. In order to get appropriate support for qualitative research, a pre and post-test containing ten basic mathematical operations, was implemented together with the Multi-vide Ruler Kit. The findings of the qualitative case study, with the pre and post-tests, showed significant differences in their achievement and interest in two-digit multiplication and division operations. The results suggest that this approach could improve PROTIM student's ability to solve basic mathematical operations. What was most encouraging was the increase in students' interest in solving numeracy problems
Flowcytometric assessment of fetomaternal hemorrhage during external cephalic version at term
No full textExternal cephalic version (ECV) at term is a safe procedure and reduces the incidence of cesarean sections for breech presentation. One of the known complications, however, is an ECV-related disruption of the placental barrier and a subsequent transfusion of fetal blood into maternal circulation. While the incidence of ECV-related fetomaternal hemorrhage (FMH) has been determined recently in a large trial using a manual Kleihauer-Betke test (KBT), questions remain on the amount of ECV-related FMH. KBT, which detects fetal red blood cells (RBC) on the basis of acidic resistance of fetal hemoglobin (HbF), is known to be a sensitive test, yet prone to procedural errors limiting its accuracy in quantifying FMH. In this study we investigated 50 patients for FMH before and after ECV, using a dual-color flow cytometric test kit with a lower limit of quantification of 0.05% fetal RBC in maternal peripheral blood. Three patients had a quantifiable increase of fetal RBC detected after ECV (0.06%; 0.08%; 0.1%). None of these subtle increments was predictable by ECV-related clinical parameters or translated into fetal compromise. Using a sensitive and accurate flow cytometric test method, our data provide further assurance to mothers on the safety of ECV at term

Downregulation of c-Kit/MITF-M in Graying Hair of Juvenile Poliosis
No full textJuvenile poliosis, also known as premature canities, occurs in young adults. The incidence of this condition is about 15-32% in the Chinese population. The mechanism of juvenile poliosis is currently poorly understood but is thought to be related to inheritance and nutrition. Hair pigmentation depends entirely on the presence of melanin, produced by melanocytes. The active melanocytes of the bulb are essential, because they produce and transfer melanin to the cortical keratinocytes of the shaft (1, 2). A reduction in tyrosinase (TYR) activity, suboptimal melanocyte-cortical keratinocyte interactions, and defective migration of melanocytes can all lead to pigment dilution or true grayness (3). Melanocytes of the follicular pigmentary unit are derived from the neural crest and melanogenesis is tightly regulated by several factors, including microphthalmia-associated transcription factor (MITF), the Paired box 3 (Pax3), the Sry-related HMG box 10 (Sox10), tyrosine kinase receptor c-Kit and others (4). MITF-M isoforms have been reported to be expressed in the hair bulb and in the melanocyte stem cells in the bulge area. MITF-M is a key transcription factor regulating the expression of tyrosinase, and is also associated with the migration, survival, and differentiation/proliferation of melanocytes (5). Pax3 can increase MITF expression by binding to its promoter and simultaneously prevent MITF from activating downstream genes by competition for enhancer occupancy in melanocyte precursors. Sox10 is expressed in melanoblasts, which can directly transactivate the MITF gene and cooperate with MITF to activate tyrosinase expression (6, 7). The tyrosine kinase receptor, c-Kit, is also important for melanocyte survival during development, and mutations in these genes result in unpigmented hairs (8). Furthermore, immature melanocytes must express c-Kit as a prerequisite for migration into the stem cell factor-supplying hair follicle epithelium. Differentiating c-Kit-positive melanocytes appear to target the hair bulb (4). The present study seeks to explore the expression of genes related to melanogenesis in relation to the mechanism of juvenile poliosis.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000339416100031&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701DermatologySCI(E)[email protected]
