Influence of Link Structure on Search Engine Result Pages of Online Nursery Shops

The primary objective of this thesis is to assess how the backlink portfolio structure and off site Search Engine Optimisation (SEO) elements influence ranking of UK based online nursery shops. The growth of the internet use demanded significant effort from companies to optimize and increase their online presence in order to cope with the increasing online competition. The new e-Commerce technology - called Search Engine Optimisation - has been developed that helped increase website visibility of companies. The SEO process involves on site elements (i.e. changing the parameters of the company's website such as keywords, title tags and meta descriptions) and off site elements (link building and social media marketing activity). Link Building is based on several steps of marketing planning including keyword research and competitor analysis. The underlying goal of keyword research is to understand the targeted market through identifying relevant keyword queries that are used by targeted costumer group. In the analysis, three types (geographic, field and company’s strategy related) and seven sources of keywords has been identified and used as a base of analysis. Following the determination of the most popular keywords, allinanchor and allintitle search has been conducted and the first ten results of the searches have been collected to identify the companies with the most significant web presence among the nursery shops. Finally, Link Profiling has been performed where the essential goal was to understand to what extent other companies' link structure is different that the base company's backlinks. Significant difference has been found that distinguished the top three companies ranking in the allinanchor and allintitle search. The top three companies, „Mothercare”, „Mamas and Papas” and „Kiddicare” maintained significantly better metrics regarding domain and page authority on the main landing pages, the average number of outbound links for link portfolio metric and in number of backlinks. These companies also ranked among the highest in page authority distribution and followed external linking.

Development of porous glass-fiber reinforced composite for bone implants. Evaluation of antimicrobial effect and implant fixation

Cranial bone reconstructions are necessary for correcting large skull bone defects due to trauma, tumors, infections and craniotomies. Traditional synthetic implant materials include solid or mesh titanium, various plastics and ceramics. Recently, biostable glass-fiber reinforced composites (FRC), which are based on bifunctional methacrylate resin, were introduced as novel implant solution. FRCs were originally developed and clinically used in dental applications. As a result of further in vitro and in vivo testing, these composites were also approved for clinical use in cranial surgery. To date, reconstructions of large bone defects were performed in 35 patients. This thesis is dedicated to the development of a novel FRC-based implant for cranial reconstructions. The proposed multi-component implant consists of three main parts: (i) porous FRC structure; (ii) bioactive glass granules embedded between FRC layers and (iii) a silver-polysaccharide nanocomposite coating. The porosity of the FRC structure should allow bone ingrowth. Bioactive glass as an osteopromotive material is expected to stimulate the formation of new bone. The polysaccharide coating is expected to prevent bacterial colonization of the implant. The FRC implants developed in this study are based on the porous network of randomly-oriented E-glass fibers bound together by non-resorbable photopolymerizable methacrylate resin. These structures had a total porosity of 10–70 volume %, of which > 70% were open pores. The pore sizes > 100 μm were in the biologically-relevant range (50-400 μm), which is essential for vascularization and bone ingrowth. Bone ingrowth into these structures was simulated by imbedding of porous FRC specimens in gypsum. Results of push-out tests indicated the increase in the shear strength and fracture toughness of the interface with the increase in the total porosity of FRC specimens. The osteopromotive effect of bioactive glass is based on its dissolution in the physiological environment. Here, calcium and phosphate ions, released from the glass, precipitated on the glass surface and its proximity (the FRC) and formed bone-like apatite. The biomineralization of the FRC structure, due to the bioactive glass reactions, was studied in Simulated Body Fluid (SBF) in static and dynamic conditions. An antimicrobial, non-cytotoxic polysaccharide coating, containing silver nanoparticles, was obtained through strong electrostatic interactions with the surface of FRC. In in vitro conditions the lactose-modified chitosan (chitlac) coating showed no signs of degradation within seven days of exposure to lysozyme or one day to hydrogen peroxide (H2O2). The antimicrobial efficacy of the coating was tested against Staphylococcus aureus and Pseudomonas aeruginosa. The contact-active coating had an excellent short time antimicrobial effect. The coating neither affected the initial adhesion of microorganisms to the implant surface nor the biofilm formation after 24 h and 72 h of incubation. Silver ions released to the aqueous environment led to a reduction of bacterial growth in the culture medium.

Selvitys Eduskunnan lisärakennuksen taidekilpailusta

The purpose of this thesis was to investigate how and why an art competition was arranged to select pieces for the parliamentary annexe building in Helsinki. There is an emphasis on the cultural production aspects of the research. For the purpose of comparison, the thesis also examines how art acquisition takes place in the cities of Helsinki, Salo and Vantaa, and how the so-called percentage principle has been used in these cities The research method involved thematic interviewing of four persons with central positions on the competition jury. Questions were also sent by e-mail to experts and other people with knowledge of the subject area. Although art competitions have been arranged in Finland for decades, very little relevant literature exists. In addition to the interviews, other relevant literature was also referred to, including parliamentary records. The crucial questions concerned why the art competition for the parliamentary annexe was arranged and whether, indeed, it is possible to compete artistically in this manner. The thesis also examined the relationship between art and architecture and how the best works were selected from the vast range of submissions. The answers were both honest and interesting. The thesis presents a step-by-step analysis of the competition's progress over two stages, and according to the specific rules for such competitions as laid out in Suomen Taiteilijaseura. Strict adherence to the rules of the competition created a number of problems, some of which are also studied. The primary reason for staging a competition was to be as democratic as possible, and eliminating any possibility of nominating a particular artist or artists to realise their own work within the annexe. The competition opened up the possibility to consider various artistic proposals, and no genres were ruled out in advance. This format ensured a good response and a total of 1719 proposals were received, of which six were eventually selected. One conclusion was that open competition may not be the best way to gather artistic proposals in such circumstances, but it is very democratic.

Julkisen osakeyhtiön omien osakkeiden hankinta ja niiden kirjanpidollinen käsittely. Case HEXTech - Indeksin yhtiöt

Tavoitteena on selvittää ja kuvata lainsäädännön kehitys julkisen osakeyhtiön omien osakkeiden hankinnassa ja esittämisessä tilinpäätöksessä sekä miten teoriaa sovelletaan käytännössä julkisiin osakeyhtiöihin. Lähestymistapa on teoriasidonnainen, säädöstaustaan perustuva ja analyysin perustana ovat dokumentoidut säädökset. Tutkimusmenetelmä on deskriptiivinen tapaustutkimus, jonka analyysi rajoittuu vuoteen 2005. Tutkimustyön sisältö koostuu julkisesti noteerattujen osakeyhtiöiden omien osakkeiden hankkimisesta ja esittämisestä tilinpäätöksessä koskevista EuroopanUnionin direktiivien sisällön käsittelystä, niiden vaikutuksesta osakeyhtiö-, kirjanpito- ja arvopaperimarkkinalakiin sekä HEXTech - Indeksin yhtiöiden käytäntöön. Tätä käytäntöä selvitetään ja kuvataan tutkimusosuudessa. Tutkimustuloksena voidaan todeta, että lait on harmonisoitu Euroopan Yhteisöjen direktiivejä vastaavaksi. HEXTech - Indeksin yhtiöt ovat noudattaneet kirjanpito-, osakeyhtiö- ja arvopaperimarkkinalain ohjeita ja määräyksiä käytännöissään. Yhtiökokoukselta on saatu valtuutuksia hankkia omia osakkeita.Kymmenestä yhtiöstä seitsemän oli saanut valtuutuksen ja vain neljä toteutti käytännössä saamansa valtuutuksen. Kaksi yhtiötä mitätöi, yksi kannusti avainhenkilöitään hankkimillaan omilla osakkeilla ja yksi toteutti takaisinostotarjouksella omien osakkeiden hankinnan.
