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.

Link-16 -järjestelmän käyttö puolustusvoimissa

Kehitys tietotekniikan puolella on viime vuosina ollut huimaa. Tämä on näkynyt kaikkialla yhteiskunnassa, muun muassa digitelevision esiinmarssina. Myös ilmailussa, sekä siviili- että sotilasilmailussa, on ryhdytty kartoittamaan uuden tekniikan hyväksikäyttömahdollisuuksia. Tämän työn tarkoituksena on tarkastella, miten NATO:n käyttämää datalinkkijärjestelmää, Link-16 -järjestelmää, voitaisiin käyttää Suomen Puolustusvoimien yhteisoperaatioissa sekä ilmavoimien omissa operaatioissa. Yhteisoperaation datalinkkijärjestelmälle asettamia vaatimuksia on pyritty kartoittamaan sovelletun vaatimusmäärittelyn menetelmin. Näin ollen työssä on pureuduttu vähän myös yhteisoperaatioihin ja niiden perusteisiin. Link-16 - järjestelmän ominaisuuksia on verrattu vaatimusmäärittelyn tuottamiin vaatimuksiin, minkä kautta on saatu kuva järjestelmän käyttökelpoisuudesta. Työssä on pohdittu myös, millaisia ongelmia Link-16 -järjestelmän käyttöönotto Suomessa saattaisi aiheuttaa. Tuloksia tarkasteltaessa korostuu Link-16 -järjestelmän vaatima suunnittelu- ja hallinnointityö. Järjestelmän tarjoaman joustavan verkkosuunnittelun avulla voidaan luoda haluttuja verkkoja, mutta suunnittelussa pitää pyrkiä ottamaan huomioon kaikki mahdollisesti eteen tulevat tilanteet. Eri operaatioille pitää myös suunnitella eri viestiverkot. Ilmavoimien omille operaatioille saattaa muodostua ongelmaksi järjestelmän käyttömahdollisuusmoodeista johtuva varakoneen hankala käyttöönotto. Link-16 -järjestelmä käyttää samaa taajuuskaistaa kuin ilmailussa käytettävä Distance Measurement Equipment (DME) -järjestelmä. Tästä johtuen maailmalla on luotu tiettyjä sääntöjä, joiden puitteissa Link-16 -järjestelmien päätelaitteiden on toimittava, jotta ne eivät häiritsisi DME-laitteiden toimintaa. Kyseiset säännöt lisäävät entisestään Link-16 -käyttäjien hallinnollista työmäärää. Rajoituksista johtuen kaikkia operaatioita on suunniteltava ja johdettava tarkasti, jotta Link-16 -järjestelmälle asetetut EMC-rajoitukset eivät ylittyisi. Link- 16 -järjestelmän käyttö vaatii siis huomattavasti hallinnollista työtä. Suomen Ilmavoimat tutkii tällä hetkellä, minkälaisia organisatorisia muutoksia Link-16 -järjestelmän käyttöönotto ilmavoimille merkitsisi. Mikäli halutaan osallistua kansainvälisiin kriisinhallintaoperaatioihin yhdessä muiden NATO -maiden kanssa, Link-16 -järjestelmä on käytännössä pakollinen.

Efeitos do acido giberélico (GA) e do cloreto de clorocolina (CCC) sobre o crescimento inicial de Brachiaria plantaginea (Link) Hitch

Com o objetivo de verificar os efeitos do ácido giberélico (GA) e do cloreto de clorocolina (CCC) sobre o crescimento e desenvolvimento inicial de Brachiaria plantaginea, instalou-se a presente pesquisa em local com alta infestação dessa espécie, utilizando-se dos seguintes tratamentos: CCC nas concentrações de 1000 e 2000 ppm, GA na de 50 e 100 ppm e uma testemunha sem aplicação dos fitoreguladores. Na época de aplicação dos produtos as plantas apresentavam, em média, sete folhas e idade em torno de 25 dias. Os parâmetros avaliados foram altura do dossel, altura média das plantas, número médio de perfilhos por planta, biomassa seca da parte aérea total e por indivíduo. Os resultados foram avaliados 22 dias após a aplicação, quando se verificou que a biomassa total das plantas não foi alterada significativamente pelos tratamentos. Não ocorreram efeitos de doses e nem de interações entre fitoreguladores com dose em quaisquer dos parâmetros avaliados. Não se verificaram efeitos do CCC nos dados obtidos e todas as alterações ocorridas foram devidas à aplicação do GA que aumentou, significativamente, a altura de dossel e dos indivíduos de Brachiaria plantaginea e reduziu o perfilhamento da planta daninha.

Redução da interferência de Brachiaria plantaginea (link) hitch. em milho através de capinas e aplicação de herbicidas em diferentes épocas

O rendimento de grãos de milho é afetado pela interferência com as plantas daninhas, que pode variar em função da eficiência e da época de realização do método de controle utilizado no manejo da cultura. O objetivo deste trabalho foi determinar os efeitos da aplicação de herbicidas e de capinas em diferentes épocas sobre o controle de plantas daninhas e o rendimento de grãos na cultura do milho. O experimento foi instalado no sistema convencional de preparo do solo em Eldorado do Sul (RS), no ano agrícola 1997/98. A espécie de planta daninha predominante na área experimental foi Brachiaria plantaginea (BRAPL), em infestação média de 285 plantas por m². Os tratamentos foram constituídos pela aplicação isolada, seqüencial ou em mistura em tanque, em diferentes doses e épocas, dos herbicidas atrazine, atrazine + óleo vegetal, metolachlor e nicosulfuron. Todos os tratamentos com herbicidas foram correspondidos por tratamentos em que se utilizou capina manual com início na mesma época de aplicação dos herbicidas. O controle realizado em pré-emergência ou no início do desenvolvimento da cultura proporcionou maior rendimento de grãos, mesmo com a diminuição do controle de BRAPL no final do ciclo. As aplicações seqüenciais de herbicidas proporcionaram maior rendimento de grãos do que as misturas em tanque. Os rendimentos de grãos obtidos com a aplicação de herbicidas nas diversas épocas não foram diferentes em relação às suas respectivas capinas.

The obstacles for cross-border transmission network investments in the Nordic electricity market: Case South-West link

The Nordic electricity market is often seen as an example of how to create a working, developed and integrated electricity market. Nevertheless, this thesis studies the obstacles of transmission network investments and the market integration challenges in the Nordic electricity market. The main focus is in the Nordic Transmission system operators (TSOs), which have a key role in grid development. This study introduces a case study of cancellation of South-West link, Western part, which was seen as essential grid investment in order to improve the Nordic electricity market functioning but ended up with cancellation in 2013. This study includes semi-structured theme interviews of the experts among Nordic electricity industry stakeholders. Despite the political will to create more equal prices for electricity in the Nordic market, the differing national regulation, mixed incentives created by bottleneck income and the focus moving from Nordic integration to European integration may create challenges to the Nordic electricity market integration in the future.

ClC-5 chloride channel and kidney stones: what is the link?

Nephrolithiasis is one of the most common diseases in the Western world. The disease manifests itself with intensive pain, sporadic infections, and, sometimes, renal failure. The symptoms are due to the appearance of urinary stones (calculi) which are formed mainly by calcium salts. These calcium salts precipitate in the renal papillae and/or within the collecting ducts. Inherited forms of nephrolithiasis related to chromosome X (X-linked hypercalciuric nephrolithiasis or XLN) have been recently described. Hypercalciuria, nephrocalcinosis, and male predominance are the major characteristics of these diseases. The gene responsible for the XLN forms of kidney stones was cloned and characterized as a chloride channel called ClC-5. The ClC-5 chloride channel belongs to a superfamily of voltage-gated chloride channels, whose physiological roles are not completely understood. The objective of the present review is to identify recent advances in the molecular pathology of nephrolithiasis, with emphasis on XLN. We also try to establish a link between a chloride channel like ClC-5, hypercalciuria, failure in urine acidification and protein endocytosis, which could explain the symptoms exhibited by XLN patients.

A link between sleep loss, glucose metabolism and adipokines

The present review evaluates the role of sleep and its alteration in triggering problems of glucose metabolism and the possible involvement of adipokines in this process. A reduction in the amount of time spent sleeping has become an endemic condition in modern society, and a search of the current literature has found important associations between sleep loss and alterations of nutritional and metabolic contexts. Studies suggest that sleep loss is associated with problems in glucose metabolism and a higher risk for the development of insulin resistance and type 2 diabetes mellitus. The mechanism involved may be associated with the decreased efficacy of regulation of the hypothalamus-pituitary-adrenal axis by negative feedback mechanisms in sleep-deprivation conditions. In addition, changes in the circadian pattern of growth hormone (GH) secretion might also contribute to the alterations in glucose regulation observed during sleep loss. On the other hand, sleep deprivation stress affects adipokines - increasing tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) and decreasing leptin and adiponectin -, thus establishing a possible association between sleep-debt, adipokines and glucose metabolism. Thus, a modified release of adipokines resulting from sleep deprivation could lead to a chronic sub-inflammatory state that could play a central role in the development of insulin resistance and type 2 diabetes mellitus. Further studies are necessary to investigate the role of sleep loss in adipokine release and its relationship with glucose metabolism.

Resistência de quatro genótipos de amendoim à produção de aflatoxina B1 após inoculação com Aspergillus flavus Link

Avaliou-se a produção de aflatoxina B1 pelo Aspergillus flavus IMI 190443, inoculado em sementes de genótipos de amendoim: Tatu Vermelho, VRR-245, 2117 e 2155, in natura e autoclavado a 1210 C por 20 minutos, previamente cultivados no Centro Experimental do Instituto Agronômico de Campinas, em 1995/96. A aflatoxina B1 foi quantificada por cromatografia em camada delgada, utilizando comparação visual com padrões. Os níveis de aflatoxina B1 das amostras autoclavadas e in natura dos genótipos Tatu Vermelho, VRR-245 e 2155 foram significativamente diferentes (p <0,05, Teste de Duncan) quando comparados aos níveis do genótipo 2117. O genótipo 2117, originário da Índia, apresentou independente do processo com e sem aquecimento os menores níveis de aflatoxina B1 em relação aos dos outros genótipos. Os resultados obtidos mostram perspectivas de exploração da resistência varietal no controle da aflatoxina.

Implementing Green IT approach for transferring Big Data over Parallel Data Link

The whole research of the current Master Thesis project is related to Big Data transfer over Parallel Data Link and my main objective is to assist the Saint-Petersburg National Research University ITMO research team to accomplish this project and apply Green IT methods for the data transfer system. The goal of the team is to transfer Big Data by using parallel data links with SDN Openflow approach. My task as a team member was to compare existing data transfer applications in case to verify which results the highest data transfer speed in which occasions and explain the reasons. In the context of this thesis work a comparison between 5 different utilities was done, which including Fast Data Transfer (FDT), BBCP, BBFTP, GridFTP, and FTS3. A number of scripts where developed which consist of creating random binary data to be incompressible to have fair comparison between utilities, execute the Utilities with specified parameters, create log files, results, system parameters, and plot graphs to compare the results. Transferring such an enormous variety of data can take a long time, and hence, the necessity appears to reduce the energy consumption to make them greener. In the context of Green IT approach, our team used Cloud Computing infrastructure called OpenStack. It’s more efficient to allocated specific amount of hardware resources to test different scenarios rather than using the whole resources from our testbed. Testing our implementation with OpenStack infrastructure results that the virtual channel does not consist of any traffic and we can achieve the highest possible throughput. After receiving the final results we are in place to identify which utilities produce faster data transfer in different scenarios with specific TCP parameters and we can use them in real network data links.

On site measurements of DC link electrolytic capacitor bank of frequency converter using constant DC magnetization of the motor

Preventive maintenance of frequency converters has been based on pre-planned replace-ment of wearing or ageing components. Exchange intervals follow component life-time expectations which are based on empirical knowledge or schedules defined by manufac-turer. However, the lifetime of a component can vary significantly, because drives are used in very different operating environments and applications. The main objective of the research was to provide information on methods, i.e. how in-verter's operating condition can be measured reliably under field conditions. At first, the research focused on critical components such as current transducers, IGBTs and DC link capacitor bank, because these aging have already been identified. Of these, the DC link capacitor measurement method was selected for closer examination. With this method, the total capacitance and its total series resistance can be measured. The suitability of the measuring procedure was estimated on the basis of practical measurements. The research was made by using so called triangulation method, including a literature review, simulations and practical measurements. Based on the results, the new measu-rement method seems suitable with some reservations to practical measurements. How-ever, the measuring method should be further developed in order to improve its reliability.
