Description of Lyme disease-like syndrome in Brazil: is it a new tick borne disease or Lyme disease variation?

An emerging clinical entity that reproduces clinical manifestations similar to those observed in Lyme disease (LD) has been recently under discussion in Brazil. Due to etiological and laboratory particularities it is named LD-like syndrome or LD imitator syndrome. The condition is considered to be a zoonosis transmitted by ticks of the genus Amblyomma, possibly caused by interaction of multiple fastidious microorganisms originating a protean clinical picture, including neurological, osteoarticular and erythema migrans-like lesions. When peripheral blood of patients with LD-like syndrome is viewed under a dark-field microscope, mobile uncultivable spirochete-like bacteria are observed. PCR carried out with specific or conservative primers to recognize Borrelia burgdorferi sensu stricto or the genus Borrelia has been negative in ticks and in biological samples. Two different procedures, respectively involving hematoxylin and eosin staining of cerebrospinal fluid and electron microscopy analysis of blood, have revealed spirochetes not belonging to the genera Borrelia, Leptospira or Treponema. Surprisingly, co-infection with microorganisms resembling Mycoplasma and Chlamydia was observed on one occasion by electron microscopy analysis. We discuss here the possible existence of a new tick-borne disease in Brazil imitating LD, except for a higher frequency of recurrence episodes observed along prolonged clinical follow-up.

Neuvostojoukot Itä-Saksassa kylmän sodan aikana

Toisen maailmansodan päättymisen ja Potsdamin sopimuksen seurauksena Saksa jakautui Länsi- ja Itä-Saksaksi. Länsi-Saksan hallinnosta vastasivat Yhdysvallat, Iso- Britannia ja Ranska. Itä-Saksasta puolestaan tuli kokonaisuudessaan Neuvostoliiton hallinnassa ollut alue. Neuvostoliiton ja länsivaltojen näkemykset siitä, miten sodanjälkeistä Saksaa tulisi hallinnoida, erosivat suuresti toisistaan alusta lähtien, ollen yksi merkittävimmistä tekijöistä kylmän sodan syttymisen taustalla. Koko kylmän sodan ajan mahdollisen aseellisen konfliktin nähtiin alkavan Euroopasta, mitä todennäköisimmin Saksasta. Tämän vuoksi länsivallat ja Neuvostoliitto sijoittivat alueelle paljon sotilaallista voimaa. Kyseisen sotilaallisen voiman keskittymän seurauksena syntyi kaksi maailmanhistorian suurinta sotilasliittoutumaa: Nato ja Varsovan liitto. Näistä kahdesta sotilasliitosta ensimmäiseksi luotiin Nato vuonna 1949. Vuonna 1955 Neuvostoliitto vastasi tähän uuteen strategisen tason uhkaan luomalla Varsovan liiton. Varsovan liiton perustamista seurasi Itä-Saksan kansanarmeijan eli NVA:n perustaminen. NVA:n joukot olivat Neuvostoliiton sotilasjohdon alaisuudessa toimineita joukkoja, ja ne varustettiin Neuvostoliiton parhaimmalla kalustolla läpi kylmän sodan. Tästä esimerkkinä NVA:n varustaminen ydinaseilla 1960-luvulla. Itä-Saksan miehitystä kesti vuoteen 1994 asti, jolloin viimeiset Neuvostoliiton aikaiset miehitysjoukot poistuivat sen maaperältä. Neuvostoliiton kaatumiseen asti Itä-Saksan miehitysjoukot olivat ylivoimaisesti suurin Neuvostojoukkojen keskittymä sen omien rajojen ulkopuolella. Aluetta miehitti jatkuvasti noin 16–24 divisioonaa, jotka olivat täysivahvuisia ja hyvin koulutettuja. Näiden joukkojen liikkeellelähtövalmius oli jopa alle 24 tuntia, joka antaa hyvän kuvan siitä, miten kriittinen alue Itä-Saksa Neuvostoliitolle todellisuudessa oli.

Intellectual Capital Measurement in IT industry

The goal of this research – which is to critically analyze current theories and methods of intangible assets evaluation and potentially develop and test new methodology based on the practical example(s) in the IT industry. Having this goal in mind the main research questions in this paper will be: What are advantages and disadvantages of the current practices of measurement intellectual capital or valuation of intangible assets? How to properly measure intellectual capital in IT? Resulting method exhibits a new unique approach to the IC measurement and potentially even larger field of application. Despite the fact that in this particular research, I focused my attention on IT (Software and Internet services cluster – to be exact), the logic behind the method is applicable within any industry since the method is designed to be fully compliant with measurement theory and thus can be properly scaled for any application. Building a new method is a difficult and iterative process: in the current iteration the method stands out as rather a theoretical concept rather than a business tool, however even current concept totally fulfills its purpose as a benchmarking tool for measuring intellectual capital in IT industry.

Asthma: where is it going?

Asthma is characterized by reversible airway obstruction, airway hyperresponsiveness, and airway inflammation. Although our understanding of its pathophysiological mechanisms continues to evolve, the relative contributions of airway hyperresponsiveness and inflammation are still debated. The first mechanism identified as important for asthma was bronchial hyperresponsiveness. In a second step, asthma was recognized also as an inflammatory disease, with chronic inflammation inducing structural changes or remodeling. However, persistence of airway dysfunction despite inflammatory control is observed in chronic severe asthma of both adults and children. More recently, a potential role for epithelial-mesenchymal communication or transition is emerging, with epithelial injury often resulting in a self-sustaining phenotype of wound repair modulation by activation/reactivation of the epithelial-mesenchymal trophic unit, suggesting that chronic asthma can be more than an inflammatory disease. It is noteworthy that the gene-environmental interactions critical for the development of a full asthma phenotype involve processes similar to those occurring in branching morphogenesis. In addition, a central role for airway smooth muscle in the pathogenesis of the disease has been explored, highlighting its secretory function as well as different intrinsic properties compared to normal subjects. These new concepts can potentially shed light on the mechanisms underlying some asthma phenotypes and improve our understanding of the disease in terms of the therapeutic strategies to be applied. How we understand asthma and its mechanisms along time will be the focus of this overview.

Influência de embalagens e temperatura no armazenamento de jabuticabas (Myrciaria jabuticaba (Vell) Berg) cv 'SABARÁ'

Foram avaliadas jabuticabas 'sabará' maduras, acondicionadas em bandejas de polietileno tereftalato, revestidas externamente com filme plástico de PVC, esticável e alto aderente, de 12 e 20 micras, e em bandejas de poliestireno expandido, revestidas externamente com filme plástico de PVC, esticável e alto aderente, de 12 e 20 micras. Cada bandeja recebeu 25 frutos. As bandejas foram armazenadas à temperatura de 11±1ºC com 98%UR e em condições de ambiente (23,6 a 28,3ºC com 53,7 a 68,3%UR). Como controle utilizaram-se frutos acondicionados em bandejas de polietileno tereftalato (12x20x5cm) não recobertas com filme plástico. Considerando-se os resultados obtidos pode-se concluir que o uso de embalagem associada à baixa temperatura reduziu a perda de massa fresca, prolongou a vida-útil dos frutos com manutenção da aparência até 6 dias, não influenciou na evolução dos teores de acidez total titulável, sólidos solúveis totais e pH, mas interferiu na evolução de carboidratos solúveis e vitamina C. Os frutos acondicionados não recobertos com filme plástico e armazenados em condições ambiente resistiram 2 dias, mas ao final não apresentaram aparência aceitável para comercialização, pois haviam emurchecido e enrugado. As condições de refrigeração (11±1ºC) melhoraram a resistência dos frutos acondicionados não recobertos com filmes plásticos, entretanto, após 4 dias apresentaram má aparência.

Aineettomien riskien hallinta – case Itä-Suomen Biopankki

Aineeton pääoma nähdään organisaation keskeisenä kilpailutekijänä ja voimavarana. Se voi kuitenkin joissain tilanteissa olla organisaatiolle myös rasite tai jopa menestymistä heikentävä tekijä. Tutkimuksen tavoitteena oli laatia biopankin riskienhallinnalle malli, joka huomioi toimintaan vaikuttavat aineettomat riskitekijät ja toimii strategisena johtamisen ja toiminnan kehittämisen työvälineenä. Tutkimus toteutettiin tapaustutkimuksena, jossa käytettiin konstruktiivista tutkimusotetta. Biopankille luotiin konstruktio, riskienhallintamalli, jolla pyrittiin ratkaisemaan reaalimaailman ongelma ja samalla luomaan kontribuutiota tieteenalalle. Biopankki on uudentyyppinen organisaatio, joka kerää, hallinnoi ja säilyttää biologisia ihmisperäisiä näytteitä ja niihin liittyviä tietoja tulevaa tutkimusta varten. Toiminnan riskien taustasyyt ovat usein aineettomia, kuten toimintakulttuuri, asenne, osaaminen tai motivaatio. Tutkimuksessa löydettiin uusia biopankin toimintaan kytkeytyviä aineettomia riskejä koko aineettoman pääoman alueelta ja määriteltiin riskitasoihin perustuva lähestymistapa riskien hallintaan. Konstruktio aineettomien riskien hallintamalliksi sai selkeää vahvistusta tutkimuksen aineistosta, ja se voi toimia organisaation kehittämisen pohjana. Riskikartan luominen ja riskien arviointi ovat tekohetken poikkileikkauksia tilanteesta. Organisaation toiminta ja siihen kohdistuvat riskit ja mahdollisuudet muuttuvat ja kehittyvät. Riskien tunnistaminen lisää tietoa organisaatiosta ja sen toimintaympäristöstä, mikä luo puitteet myös uusien mahdollisuuksien tunnistamiselle. Sopivan riskienhallintamallin avulla voidaan löytää kilpailuetua suhteessa muihin organisaatioihin. Kilpailuetuna voi toimia myös muita parempi riskinkantokyky esimerkiksi toiminnan joustavuuden kautta.

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.

Green Service Level Agreement under Sustainability Lens in IT Industry

Nowadays, when most of the business are moving forward to sustainability by providing or getting different services from different vendors, Service Level Agreement (SLA) becomes very important for both the business providers/vendors and as well as for users/customers. There are many ways to inform users/customers about various services with its inherent execution functionalities and even non-functional/Quality of Services (QoS) aspects through negotiating, evaluating or monitoring SLAs. However, these traditional SLA actually do not cover eco-efficient green issues or IT ethics issues for sustainability. That is why green SLA (GSLA) should come into play. GSLA is a formal agreement incorporating all the traditional commitments as well as green issues and ethics issues in IT business sectors. GSLA research would survey on different traditional SLA parameters for various services like as network, compute, storage and multimedia in IT business areas. At the same time, this survey could focus on finding the gaps and incorporation of these traditional SLA parameters with green issues for all these mentioned services. This research is mainly points on integration of green parameters in existing SLAs, defining GSLA with new green performance indicators and their measurable units. Finally, a GSLA template could define compiling all the green indicators such as recycling, radio-wave, toxic material usage, obsolescence indication, ICT product life cycles, energy cost etc for sustainable development. Moreover, people’s interaction and IT ethics issues such as security and privacy, user satisfaction, intellectual property right, user reliability, confidentiality etc could also need to add for proposing a new GSLA. However, integration of new and existing performance indicators in the proposed GSLA for sustainable development could be difficult for ICT engineers. Therefore, this research also discovers the management complexity of proposed green SLA through designing a general informational model and analyses of all the relationships, dependencies and effects between various newly identified services under sustainability pillars. However, sustainability could only be achieved through proper implementation of newly proposed GSLA, which largely depends on monitoring the performance of the green indicators. Therefore, this research focuses on monitoring and evaluating phase of GSLA indicators through the interactions with traditional basic SLA indicators, which would help to achieve proper implementation of future GSLA. Finally, this newly proposed GSLA informational model and monitoring aspects could definitely help different service providers/vendors to design their future business strategy in this new transitional sustainable society.

Digital content and making it viral in social media

Tutkimuksen tavoite on selvittää digitaalisen sisällön ominaisuuksia, jotka vaikuttavat ryhtyvätkö kuluttajat jakamaan, tykkäämään ja kommentoimaan sitä sosiaalisessa mediassa. Tällä pyritään auttamaan yrityksiä ymmärtämään paremmin viraalisuutta, jotta he pystyisivät tuottamaan ja julkaisemaan nettisivuillaan ja sosiaalisessa mediassa parempaa sisältöä, jota kuluttajat jakaisivat enemmän. Tutkimus toteutetaan muodostamalla hypoteeseja mahdollisista ominaisuuksista kirjallisuuden perusteella ja testaamalla niitä regressioanalyyseillä empiirisessä osiossa. Tulokset paljastavat yhdeksän piirrettä, jotka lisäävät viraalisuutta: kiinnostavuus, neutraalisuus, yllättävyys, viihdyttävyys, epäkäytännöllisyys, artikkelin ja Facebook julkaisun pituus, eri sisältö taktiikoiden käyttö (erityisesti blogit ja kuvat lisäävät viraalisuutta) sekä kun mielipidevaikuttaja tai kuuluisuus jakaa sisällön.

Composição química dos frutos de Campomanesia adamantium (Cambessédes) O.Berg

Frutos de C. adamantium (Myrtaceae), coletados em diferentes estádios de amadurecimento na Floresta Estadual de Assis - São Paulo -, foram avaliados quanto à composição nutricional, perfil de óleo volátil e presença de elementos inorgânicos. O fruto apresentou alto teor de água (75,9%), baixo pH (4,3) e elevada acidez (1,2 g em ácido cítrico). Além disso, destacou-se como excelente fonte de vitamina C (234 mg 100 g-1). No óleo volátil, foi possível identificar 40 componentes que corresponderam a 93,3% dos compostos presentes. Como componentes majoritários do óleo, destacaram-se o alfa-pineno (10,6%), limoneno (10,1%) e o beta-(z)-ocimeno (9,2%). Entre os minerais (16), os principais constituintes foram o K (1304 mg kg-1), Ca, P e Mg na concentração compreendida entre 165 e 175 mg kg-1 e, como micro elementos, o Fe (11,3 mg kg-1) e o Al (15,9 mg kg-1). O valor energético do fruto (66,3 kcal 100 g-1) deveu-se quase que exclusivamente aos carboidratos totais (11,6%).
