The project described in this thesis investigates the needs of a group of people working cooperatively in an OSI environment, and recommends tools and services to meet these needs. The project looks specifically at Services for Activities in Group Editing, and is identified as the `SAGE' project. The project uses case studies to identify user requirements and to determine common functionalities for a variety of group editing activities. A prototype is implemented in an X.400 environment to help refine user requirements, as a source of new ideas and to test the proposed functionalities. The conceptual modelling follows current CCITT proposals, but a new classification of group activities is proposed: Informative, Objective and Supportive application groups. It is proposed that each of these application groups have their own Service Agent. Use of this classification allows the possibility of developing three sets of tools which will cover a wide range of group activities, rather than developing tools for individual activities. Group editing is considered to be in the Supportive application group. A set of additional services and tools to support group editing are proposed in the context of the CCITT draft on group communication, X.gc. The proposed services and tools are mapped onto the X.400 series of recommendations, with the Abstract Service Definition of the operational objects defined, along with their associated component files, by extending the X.420 protocol functionality. It is proposed that each of the Informative, Objective and Supportive application groups should be implemented as a modified X.420 inter-personal messaging system.

The paper discusses facilities of computer systems for editing scientific and technical texts, which partially automate functions of human editor and thus help the writer to improve text quality. Two experimental systems LINAR and CONUT developed in 90s to control the quality of Russian scientific and technical texts are briefly described; and general principles for designing more powerful editing systems are pointed out. Features of an editing system being now under development are outlined, primarily the underlying linguistic knowledge base and procedures controlling the text.

Arginase 1 deficiency, a urea cycle disorder resulting from an inability of the body to convert arginine into urea, results in hyperargininemia and sporadic episodes of hyperammonemia. Arginase 1 deficiency can lead to a range of developmental disorders and progressive spastic diplegia in children, and current therapeutic options are limited. Clustered regularly interspaced short palindromic repeat (CRISPR) /CRISPR associated protein (Cas) 9 gene editing systems serve as a novel means of treating genetic disorders such as Arginase 1 (ARG1) deficiency, and must be thoroughly examined to determine their curative capabilities. In these experiments numerous guide RNAs and CRISPR/Cas9 systems targeting the ARG1 gene were designed and observed by heteroduplex assay for their targeting capabilities and cleavage efficiencies in multiple cell lines. The CRISPR/Cas9 system utilized in these experiments, along with a panel of guide RNAs targeting various locations in the arginase 1 gene, successfully produced targeted cleavage in HEK293, MCF7, A549, K562, HeLa, and HepG2 cells; however, targeted cleavage in human dermal fibroblasts, blood outgrowth endothelial cells, and induced pluripotent stem cells was not observed. Additionally, a CRISPR/Cas system involving partially inactivated Cas9 was capable of producing targeted DNA cleavage in intron 1 of ARG1, while a Cas protein termed Cpf1 was incapable of producing targeted cleavage. These results indicate a complex set of variables determining the CRISPR/Cas9 systems’ capabilities in the cell lines and primary cells tested. By examining epigenetic factors and alternative CRISPR/Cas9 gene targeting systems, the CRISPR/Cas9 system can be more thoroughly considered in its ability to act as a means towards editing the genome of arginase 1-deficient individuals.

The advantages of a COG (Component Object Graphic) approach to the composition of PDF pages have been set out in a previous paper [1]. However, if pages are to be composed in this way then the individual graphic objects must have known bounding boxes and must be correctly placed on the page in a process that resembles the link editing of a multi-module computer program. Ideally the linker should be able to utilize all declared resource information attached to each COG. We have investigated the use of an XML application called Personalized Print Markup Language (PPML) to control the link editing process for PDF COGs. Our experiments, though successful, have shown up the shortcomings of PPML's resource handling capabilities which are currently active at the document and page levels but which cannot be elegantly applied to individual graphic objects at a sub-page level. Proposals are put forward for modifications to PPML that would make easier any COG-based approach to page composition.

Tra le più importanti risorse alieutiche di molte regioni del Mar Mediterraneo vi sonole acciughe (Engraulisencrasicolus, Linnaeus, 1758), piccoli pesci pelagici appartenenti alle famiglie degli Engraulidae. Dati IREPA del 2009, hanno di fatto reso noto che in Italia, la pesca di E. encrasicolusha rappresentano in media il 26% circa del pescato totale. Questa specie viene continuamente monitorata e grazie a tali programmi è stato evidenziato che vi sono delle fluttuazioni inter-annuali molto pronunciate (Cergoleet al., 2002; Cingolani, 2004), le cui cause possono essere molteplici, da fattori antropicicome l’elevato sforzo di pesca a fattori naturali (Borjia et al., 1996). Va però posta molta attenzione sulle dinamiche biologiche ed ambientali che influiscono sulla sopravvivenza dei primi stadi di vita di questa specie, che ricadendo sul successivo reclutamento, possono essere una delle cause fondamentali delle contrazioni e degli incrementi annuali dello stock adulto (Thikonova et al., 2000; James et al., 2003; Cuttitta et al., 2003, 2006).Lo studio delle fasi ittioplanctoniche e delle sue relazioni con l’ambiente e gli altri organismi, risulta quindi di primaria importanza nell’ambito delle conoscenze necessarie per il corretto sfruttamento delle risorse alieutiche.

Editing a literary magazine offers us a cultural space where our ideas and aesthetics can be expressed collectively and therefore be heard more effectively. This informs and frames our own writing by increasing our confidence in our own unusual voices. The sense of belonging Brand creates further breaks down the isolation of the writing life. The internationalism of Brand reinforces our own cultural identities as non-English writers. However, acting as a facilitator of others’ creativity can sometimes dissipate or even deplete creative energy. Editing and teaching can take over your writing to the point of annihilation. Further, in terms of external perceptions, you run the risk of disappearing as a writer. We shall look at how this can happen and explore ways that we can prevent it e.g. keeping the boundaries firm and clear.

Zebrafish is a powerfulmodel for the study of vertebrate development, being amenable to a wide range of genetic and other manipulations to probe themolecular basis of development and its perturbation in disease. Over recent years, genome editing approaches have become increasingly used as an efficient and sophisticated approach to precisely engineer the zebrafish genome, which has further enhanced the utility of this organism. This review provides a practical overview of genome editing and its application in zebrafish research, including alternate strategies for introducing and screening for specific genetic changes.
