Rad Hourani : Self-Titling
No full text"“Self-titling” is a result of Rad Hourani’s observations on the art market made while attending art fairs, auctions and gallery openings. This series of artworks is a study of how art collectors and gallerists present and title themselves, with gendered names, nationalities, professions, hereditary privileges and possessions, rather than simply beings. These labels define their interactions. with this creation, Rad Hourani questions the self-assigned and illusionary categories that humans place themselves into by presenting their identities in everyday life; through this lens, he examines the purpose of creating art today.
Using the most spoken languages worldwide, the artworks are numbered in decreasing order and identified with the most common country-specific names and highest-paying positions in the most economically established places in the world. The buyer or seller thus becomes the curated work of art itself in a form of self-titled advertisement, which raises the question of whether art is created for the purpose of limitless expression or rather for the market, to be sold as a form of decoration for different clients of different statuses." -- Artist's websit
RAD Applied in the Context of Investment Banking
No full textRAD as a methodology for implementing information systems has been used in a broad range of domains utilizing technology as an informational backbone but perhaps one of the main areas where this approach has been proven to be a natural fit has been in the investment banking (IB) industry, most notably when applied to trading systems. This paper introduces some of the main tenants of RAD development and focuses on a number of case studies where RAD has proven to be an extremely suitable method for implementing solutions required in the IB industry as well as explaining why RAD may be more successful than other classic de-velopment methods when applied to IB related solutions.RAD, Information Systems, Investment Banking, Trading Systems
Special features of RAD Sequencing data:implications for genotyping
No full textRestriction site-associated DNA Sequencing (RAD-Seq) is an economical and efficient method for SNP discovery and genotyping. As with other sequencing-by-synthesis methods, RAD-Seq produces stochastic count data and requires sensitive analysis to develop or genotype markers accurately. We show that there are several sources of bias specific to RAD-Seq that are not explicitly addressed by current genotyping tools, namely restriction fragment bias, restriction site heterozygosity and PCR GC content bias. We explore the performance of existing analysis tools given these biases and discuss approaches to limiting or handling biases in RAD-Seq data. While these biases need to be taken seriously, we believe RAD loci affected by them can be excluded or processed with relative ease in most cases and that most RAD loci will be accurately genotyped by existing tools
Identification of a sex-linked SNP marker in the salmon louse (Lepeophtheirus salmonis) using RAD sequencing
No full textThe salmon louse (Lepeophtheirus salmonis (Krøyer, 1837)) is a parasitic copepod that can, if untreated, cause considerable damage to Atlantic salmon (Salmo salar Linnaeus, 1758) and incurs significant costs to the Atlantic salmon mariculture industry. Salmon lice are gonochoristic and normally show sex ratios close to 1:1. While this observation suggests that sex determination in salmon lice is genetic, with only minor environmental influences, the mechanism of sex determination in the salmon louse is unknown. This paper describes the identification of a sex-linked Single Nucleotide Polymorphism (SNP) marker, providing the first evidence for a genetic mechanism of sex determination in the salmon louse. Restriction site-associated DNA sequencing (RAD-seq) was used to isolate SNP markers in a laboratory-maintained salmon louse strain. A total of 85 million raw Illumina 100 base paired-end reads produced 281,838 unique RAD-tags across 24 unrelated individuals. RAD marker Lsa101901 showed complete association with phenotypic sex for all individuals analysed, being heterozygous in females and homozygous in males. Using an allele-specific PCR assay for genotyping, this SNP association pattern was further confirmed for three unrelated salmon louse strains, displaying complete association with phenotypic sex in a total of 96 genotyped individuals. The marker Lsa101901 was located in the coding region of the prohibitin-2 gene, which showed a sex-dependent differential expression, with mRNA levels determined by RT-qPCR about 1.8-fold higher in adult female than adult male salmon lice. This study's observations of a novel sex-linked SNP marker are consistent with sex determination in the salmon louse being genetic and following a female heterozygous system. Marker Lsa101901 provides a tool to determine the genetic sex of salmon lice, and could be useful in the development of control strategies
An investigation into the applicability of the RAD methodology when applied to the development of an information system
No full textWithin any software-related environment many tools, techniques and SDMs (Software Development Methodologies) can be applied to help control the software development lifecycle. The aim of this thesis is to assess the applicability of the RAD (Rapid Application Development) SDM to software development when designing an MIS (Management Information System) for Philips Components Washington. Both positive and negative characteristics of the approach were examined. This thesis provides detailed conclusions on each of the identified characteristics together with more general analysis of the use of SDMs. Research into several SDMs has been carried out in parallel with the development of the MIS, however the RAD SDM was predominantly used throughout the project. This study has been carried out through the analysis of information requirements around the Philips factory with an aim to providing one central system by which all production figures can be collated and reported upon. Prior to this study no standards for the choice of SDM were in place for software design, however previous SDMs used tended to be more traditional and structured in nature. Through this study, additional areas of analysis have been identified in order to further investigate the RAD SDM. Recommendations have also been provided for any future software projects that Philips may undertake with the application of the RAD methodology

ESTIMATION OF SOLAR RADIATION MODEL USING MEASURED DATA IN A SPECIFIC REGION
No full text5th International Conference on Radiation and Applications in Various Fields of Research, RAD 2017 -- 12 June 2017 through 16 June 2017 -- Budva -- 142103Nowadays, the use of solar radiation is very important for some applications. Knowledge of global solar radiation distribution is needed for the design of solar energy systems for these applications. Many parameters affect the production of solar energy and conversion efficiencies and location conditions of PV panels. One of the most vital parameters is the number of solar radiation values. The main objective of this study is to determine the predicting solar radiation by using meteorological measurements. In this study, two empirical models (linear and second-order polynomial equation) were analyzed according to correlation coefficients for a month for the global solar radiation on horizontal surface in Osmaniye and a new quadratic model has been developed for Osmaniye. © RAD Conference Proceedings.

Variability of Indoor Radon Level Accumulation: a Study in Portuguese Thermal Spas
No full textThe aim of this work was to measure the concentration of the indoor radon in 16 Portuguese thermal spas (38% of the thermal spas in Portugal) and assess its variability within each establishment as well as its contribution to the effective dose. The measurements were performed with CR-39 passive detectors placed at different workplaces within each thermal spa, for an average period of 42 days, in different seasons of the year. The indoor radon concentrations ranged from 68 to 4335 Bq/m3 with a geometric mean of 437 Bq/m3 and an arithmetic mean of 702 Bq/m3. Geological factors that can lead to such behaviour are discussed. The results showed that the EU reference level of 300 Bq/m3 (Directive 2013/59/EURATOM) was exceeded in several cases. No significant differences were observed among measurements taken during different seasons of the year, however, large differences of radon concentrations in different rooms of the same thermal establishment were noted as well as significant difference when comparing to other thermal establishments. The effective dose resulting from the inhalation of radon ranged between 2 and 32 mSv/y. In 43% of the thermal spas, the effective dose is likely to be higher than 6 mSv/y, which means that the exposure should be managed as a "planned exposure situation" according to the European Directive 2013/59/EURATOM. Also, in 19% of the cases, the annual effective dose exceeds 20 mSv/y, and in these cases, monitoring and radiological protection is required as laid down in the European Directive 2013/59/EURATOM.

Mapping and Validation of the Major Sex-Determining Region in Nile Tilapia (Oreochromis niloticus L.) Using RAD Sequencing
No full textSex in Oreochromis niloticus (Nile tilapia) is principally determined by an XX/XY locus but other genetic and environmental factors also influence sex ratio. Restriction Associated DNA (RAD) sequencing was used in two families derived from crossing XY males with females from an isogenic clonal line, in order to identify Single Nucleotide Polymorphisms (SNPs) and map the sex-determining region(s). We constructed a linkage map with 3,802 SNPs, which corresponded to 3,280 informative markers, and identified a major sex-determining region on linkage group 1, explaining nearly 96% of the phenotypic variance. This sex-determining region was mapped in a 2 cM interval, corresponding to approximately 1.2 Mb in the O. niloticus draft genome. In order to validate this, a diverse family (4 families; 96 individuals in total) and population (40 broodstock individuals) test panel were genotyped for five of the SNPs showing the highest association with phenotypic sex. From the expanded data set, SNPs Oni23063 and Oni28137 showed the highest association, which persisted both in the case of family and population data. Across the entire dataset all females were found to be homozygous for these two SNPs. Males were heterozygous, with the exception of five individuals in the population and two in the family dataset. These fish possessed the homozygous genotype expected of females. Progeny sex ratios (over 95% females) from two of the males with the "female" genotype indicated that they were neomales (XX males). Sex reversal induced by elevated temperature during sexual differentiation also resulted in phenotypic males with the "female" genotype. This study narrows down the region containing the main sex-determining locus, and provides genetic markers tightly linked to this locus, with an association that persisted across the population. These markers will be of use in refining the production of genetically male O. niloticus for aquaculture
