Sovelluskehitys React Nativella

Insinöörityössä tutustuttiin mobiilisovelluskehityksen toteutustapoihin, hybridisovellusten ohjelmistokehyksiin sekä React Native -ohjelmistokehykseen. Työn tavoitteena oli oppia React Nativen käyttöä ja kehittää sovellus, jolla on täysin yhteinen koodikanta Android- ja iOS-alustoille. React Native on ohjelmistokehys, jonka avulla voi kehittää hybridisovelluksia Android-, iOS- ja Windows Phone-alustoille. Sen toiminta pohjautuu alustakohtaisten natiivikomponenttien käsittelyyn, mikä poikkeaa perinteisistä hybridisovelluksista. Perinteiset hybridisovellukset toteutetaan web-tekniikoilla, ja ne hyödyntävät kohdealustan WebView-säiliötä. React Nativen avulla kehitetyt sovellukset ovat alustariippumattomia natiivisovelluksia. Työn teoriaosuudessa syvennyttiin React Nativen toimintaperiaatteisiin ja pyrittiin havainnollistamaan muun muassa renderöinnin toimintaa. Käytännön osuudessa kuvataan sovelluskehitystä React Nativella oman sovelluksen ja koodiesimerkkien avulla. Lopputuloksena syntyi tavoitteiden mukainen Stats Collector -mobiilisovellus. Sovelluksen avulla voi kerätä tilastoja jalkapallo-ottelusta. Sovellusta on tarkoitus kehittää lisää ja julkaista se Googlen ja Applen sovelluskaupoissa.This thesis focuses on software development with React Native. Different methods of mobile application development and hybrid frameworks are also covered. The goal of the thesis was to learn to develop applications with the React Native framework and to develop a hybrid application with a common codebase for Android and iOS. React Native is a framework for developing Android, iOS and Windows Phone applications. It uses native components directly which differs from traditional hybrid frameworks. Traditional hybrid applications are developed using web-technologies and they use WebView containers to display the content. Applications made with React Native are platform independent native apps. The theory section concentrates on the operational principles of React Native. The section tries to illustrate for example how the rendering works in React Native. The software development with React Native is also described, including code samples and screenshots from Stats Collector application. The Stats Collector application was the result of the project and it met all the objectives. The application is for collecting match statistics from a football match. The application is supposed to be released in Google’s and Apple’s app stores after some further development

Agora Teaching App

Professional development of teachers normally ends after formal collegiate education. Agora desires to help educators continually train, to learn the skills of good teaching in classrooms by using various, non-traditional methodologies. By translating Agoras current platform to an app, Agora can widen their scope and serve Latin American countries outside of Peru, where they are currently based. We will simply take their current business and course platform and provide a mobile user interface for it. By expanding the reach of Agora, Latin American teachers will be well equipped to teach their classes with innovation and effectiveness

THE LOSS OF IDENTITY OF SOME SUNDANESE CHILDREN IN BOGOR CITY DUE TO LACK OF EXPOSURE TO SUNDANESE LANGUAGE

Bogor is an area in West Java, whose native language is Sundanese. However, compared to other areas, most native speakers in Bogor City, especially children, cannot speak Sundanese. They tend to speak Bahasa Indonesia, at home and outside their home. Although Sundanese language is included in the local contents in the school curriculum, it does not help children to be able to speak Sundanese. At school this subject is considered to be one of the most difficult, not only to children whose parents are non-Sundanese but also to those of Sundanese parents. These children cannot speak their own mother tongue. Then how can they say that they are Sundanese? This certainly has made them lose their own identity. This paper will discuss some factors why Sundanese is no longer popularly used by most children in Bogor, and how they react to Sundanese language subject at school

Employment, wage structure, and the economic cycle: differences between immigrants and natives in Germany and the UK

Differences in the cyclical pattern of employment and wages of immigrants relative to natives have largely gone unnoticed in the migration literature. In this paper we show that immigrants and natives react differently to the economic cycle. Based on over two decades of micro data, our investigation is for two of the largest immigrant receiving countries in Europe which at the same time are characterised by different immigrant populations as well as different economic cycles, Germany and the UK. Understanding the magnitude, nature and possible causes of differences in responses is relevant for assessing the economic performance of immigrant communities over time. We show that there are substantial differences in cyclical responses between immigrants and natives. Our analysis illustrates the magnitude of these differences, while distinguishing between different groups of immigrants. Differences in responses may be due to differences in the skill distribution between immigrant groups and natives, or differences in demand for immigrants and natives of the same skills due to differential allocation of immigrants and natives across industries and regions. We demonstrate that substantial differences in cyclical patterns remain, even within narrowly defined groups. Finally, we estimate a more structural factor type model that, using regional variation in economic conditions, separates responses to economic shocks from a secular trend and allows us to obtain a summary measure for these differences within education groups

Use of bisulfite processing to generate high-β-O-4 content water-soluble lignosulfonates

This work was supported by EPSRC grants (EP/1518175), the Industrial Biotechnology Innovation Centre (IBioIC) (DMB Ph.D. studentship) and an EPSRC Doctoral Prize Fellowship (CSL).With lignin-first biorefineries likely to become a reality, controlled depolymerization of high-quality lignin streams to high value products has become a priority. Using bisulfite chemistry, access to a high-β-O-4 content water-soluble lignosulfonate has been achieved, allowing follow-on procedures in water to be conducted. We show that phenolic β-O-4 units preferential-ly react under acidic bisulfite conditions, whilst non-phenolic β-O-4 units react much more slowly. Exploiting this improved chemical understanding and inherent selectivity, a softwood lignosulfonate has been prepared in which phenolic β-O-4 α-sulfonation has occurred leaving significant native β-O-4 content. Use of an O-benzoylation protocol with lignin coupled with advanced 2D NMR methods has allowed detailed analysis of this and other commercial and industrial lignosulfonates. Conversion of the native β-O-4 to benzylic- oxidized β-O-4 units was followed by a selective reductive cleavage to give a premium aromatic monomer in pure form.Publisher PDFPeer reviewe

Synthesis and structural characterization of a mimetic membrane-anchored prion protein

During pathogenesis of transmissible spongiform encephalopathies (TSEs) an abnormal form (PrPSc) of the host encoded prion protein (PrPC) accumulates in insoluble fibrils and plaques. The two forms of PrP appear to have identical covalent structures, but differ in secondary and tertiary structure. Both PrPC and PrPSc have glycosylphospatidylinositol (GPI) anchors through which the protein is tethered to cell membranes. Membrane attachment has been suggested to play a role in the conversion of PrPC to PrPSc, but the majority of in vitro studies of the function, structure, folding and stability of PrP use recombinant protein lacking the GPI anchor. In order to study the effects of membranes on the structure of PrP, we synthesized a GPI anchor mimetic (GPIm), which we have covalently coupled to a genetically engineered cysteine residue at the C-terminus of recombinant PrP. The lipid anchor places the protein at the same distance from the membrane as does the naturally occurring GPI anchor. We demonstrate that PrP coupled to GPIm (PrP-GPIm) inserts into model lipid membranes and that structural information can be obtained from this membrane-anchored PrP. We show that the structure of PrP-GPIm reconstituted in phosphatidylcholine and raft membranes resembles that of PrP, without a GPI anchor, in solution. The results provide experimental evidence in support of previous suggestions that NMR structures of soluble, anchor-free forms of PrP represent the structure of cellular, membrane-anchored PrP. The availability of a lipid-anchored construct of PrP provides a unique model to investigate the effects of different lipid environments on the structure and conversion mechanisms of PrP
