Produtividade e qualidade dos frutos da laranjeira 'Pêra' clone IAC em 16 porta-enxertos na região de Bebedouro-SP

Avaliou-se a influência de 16 porta-enxertos na produtividade, nas características físicas e químicas (sólidos solúveis totais-°Brix; acidez; ratio; porcentagem de suco; índice tecnológico e tamanho dos frutos) dos frutos da laranjeira 'Pêra' [Citrus sinensis (L.) Osbeck] e na incidência e severidade da clorose variegada dos citros (CVC). O plantio do experimento foi realizado em julho de 1993, com espaçamento de 6,0 m entre linhas e 3,5 m entre plantas (476 plantas/ha). O experimento foi conduzido sem irrigação. O delineamento experimental foi em blocos ao acaso, duas plantas por parcela, três repetições e 16 tratamentos, constituídos pelas seguintes cultivares porta-enxertos: tangerineira 'Sun Chu Sha Kat' (Citrus reticulata Blanco), tangerineira 'Pectinífera' (C. reticulata), 'Shekwasha' (C. depressa Hayata), tangerineira 'Pectinífera/Shekwasha' (C. depressa Hayata), tangerineira 'Batangas' (C. reticulata), tangerineira 'Oneco' (C. reticulata), citrangor [citrange (Poncirus trifoliata Raf. x C. sinensis) x C. sinensis], citrandarin [C.sunki hort. Ex Tanaka) x Poncirus trifoliata (L.) Raf. cv. English, tangerineira 'Sunki' (C. sunki), tangerineira 'Suen-Kat' (C. sunki), tangerineira 'Nasnaran' (C. amblycarpa Ochse), tangerineira 'Venezuela' (C. reticulata), tangerineira Heen Naran (C. lycopersicaeformis hort. ex Tan. ), limoeiro 'Cravo' (C. limonia Osbeck) x tangerineira 'Cleópatra' (C. reshni hort ex Tanaka), limoeiro 'Cravo' (C. limonia), tangerineira 'Cleópatra' (C. reshni). A intensidade da clorose variegada dos citros variou em função dos porta-enxertos e não se relacionou com a produção de frutos até a quarta safra. Os porta-enxertos estudados, com exceção da tangerineira Nasnaran, proporcionaram qualidade e produções iniciais de frutos similares aos do limoeiro 'Cravo'.

Fruit quality of 'Tahiti' lime (Citrus latifolia Tanak) grafted on twelve different rootstocks

In the present work, the effect of twelve rootstocks on fruit quality of the nucellar clone IAC-5 of 'Tahiti' lime, (Citrus latifolia Tanaka) and the influence of fruit position on tree in fruit quality was evaluated in the Citrus Experimental Station of Bebedouro (EECB), located in the Bebedouro county, state of São Paulo, Brazil. A 8.0 x 5.0m planting frame was utilized. The evaluated rootstocks were: 'Carrizo' citrange (C. sinensis (L.) Osbeck x Poncirus trifoliata (L.) Raf.); the hybrids 'Rangpur' lime x 'Swingle' citrumello (C. limonia Osbeck x P. trifoliata Raf) and 'Changsha' x 'English Small'(C. sunki Hort. ex Tan. x P. trifoliata Raf.); the mandarins 'Sun Chu Sha Kat' (C. reticulata Blanco) and 'Sunki' (C. sunki Hort. ex Tanaka); the 'Rangpur' limes 'Cravo Limeira' and ' Cravo FCAV' (C. limonia Osbeck); the 'Swingle' citrumello (P. trifoliata Raf. x C. paradisi Macf.); the 'Orlando' tangelo (C. reticulata Blanco x C. paradisi Macf.) and the trifoliates cvs. 'Rubidoux', 'FCAV' and 'Flying Dragon' (P. trifoliata Raf.). The experiment was arranged in a randomized block design, with twelve treatments, six replicates and one plant per plot. The rootstocks induced differences in fruit quality; however, all the evaluated quality characteristics were within the values considered as normal and acceptable for the variety, constituting good alternative rootstocks for the 'Rangpur' lime. Additionally, the fruit position in the plant (northeastern or southwestern) had a significant influence on the external fruit color regardless of the rootstock.

Enzymatic technology to improve oil extraction from Caryocar brasiliense camb. (Pequi) Pulp.

The present study aims to compare yield and quality of pequi pulp oil when applying two distinct processes: in the first, pulp drying in a tray dryer at 60ºC was combined with enzymatic treatment and pressing to oil extraction; in the second, a simple process was carried out by combining sun-drying pulp and pressing. In this study, raw pequi fruits were collected in Mato Grosso State, Brazil. The fruits were autoclaved at 121ºC and stored under refrigeration. An enzymatic extract with pectinase and CMCase activities was used for hydrolysis of pequi pulp, prior to oil extraction. The oil extractions were carried out by hydraulic pressing, with or without enzymatic incubation. The oil content in the pequi pulp (45% w/w) and the physicochemical characteristic of the oil was determined according to standard analytical methods. Free fatty acids, peroxide values, iodine and saponification indices were respectively 1.46 mgKOH/g, 2.98 meq/kg, 49.13 and 189.40. The acidity and peroxide values were lower than the obtained values in commercial oil samples, respectively 2.48 mgKOH/g and 5.22 meq/kg. Aqueous extraction has presented lower efficiency and higher oxidation of unsaturated fatty acids. On the other hand, pequi pulp pressing at room temperature has produced better quality oil. However its efficiency is still smaller than the combined enzymatic treatment and pressing process. This combined process promotes cellular wall hydrolysis and pulp viscosity reduction, contributing to at least 20% of oil yield increase by pressing.

The first SEPServer event catalogue 68-MeV solar proton events observed at 1 AU in 1996-2010

SEPServer is a three-year collaborative project funded by the seventh framework programme (FP7-SPACE) of the European Union. The objective of the project is to provide access to state-of-the-art observations and analysis tools for the scientific community on solar energetic particle (SEP) events and related electromagnetic (EM) emissions. The project will eventually lead to better understanding of the particle acceleration and transport processes at the Sun and in the inner heliosphere. These processes lead to SEP events that form one of the key elements of space weather. In this paper we present the first results from the systematic analysis work performed on the following datasets: SOHO/ERNE, SOHO/EPHIN, ACE/EPAM, Wind/WAVES and GOES X-rays. A catalogue of SEP events at 1 AU, with complete coverage over solar cycle 23, based on high-energy (~68-MeV) protons from SOHO/ERNE and electron recordings of the events by SOHO/EPHIN and ACE/EPAM are presented. A total of 115 energetic particle events have been identified and analysed using velocity dispersion analysis (VDA) for protons and time-shifting analysis (TSA) for electrons and protons in order to infer the SEP release times at the Sun. EM observations during the times of the SEP event onset have been gathered and compared to the release time estimates of particles. Data from those events that occurred during the European day-time, i.e., those that also have observations from ground-based observatories included in SEPServer, are listed and a preliminary analysis of their associations is presented. We find that VDA results for protons can be a useful tool for the analysis of proton release times, but if the derived proton path length is out of a range of 1 AU < s[3 AU, the result of the analysis may be compromised, as indicated by the anti-correlation of the derived path length and release time delay from the asso ciated X-ray flare. The average path length derived from VDA is about 1.9 times the nominal length of the spiral magnetic field line. This implies that the path length of first-arriving MeV to deka-MeV protons is affected by interplanetary scattering. TSA of near-relativistic electrons results in a release time that shows significant scatter with respect to the EM emissions but with a trend of being delayed more with increasing distance between the flare and the nominal footpoint of the Earth-connected field line.

Produção e sazonalidade de pessegueiro e nectarineira sob florescimento espontâneo e com cianamida hidrogenada e óleo mineral

O trabalho avaliou a produção e a sazonalidade de cultivares de pessegueiro e nectarineira, com e sem o uso de cianamida hidrogenada, em dois ciclos de produção (2009 e 2010). O experimento foi desenvolvido na Faculdade de Ciências Agronômicas, UNESP, Câmpus de Botucatu-SP, localizado nas seguintes coordenadas geográficas: latitude 22º51' 55" S, longitude 48º26' 22" O e 810 m de altitude. O tipo climático predominante é o temperado quente (mesotérmico), com chuvas no verão e seca no inverno. A aplicação de cianamida hidrogenada e óleo mineral resultou numa antecipação na data do início da colheita para todas as cultivares. Também houve uma concentração no período produtivo, diminuição no ciclo de produção e aumento na produção. A avaliação do ciclo da poda à colheita sob florescimento espontâneo evidenciou que as cultivares mais precoces foram: Precocinho (81,5 dias) e Conserva 693 (87 dias). As mais tardias foram: Turmalina (141,5 dias) e CP 951 C (134,5 dias). Com o uso da cianamida hidrogenada e do óleo mineral, o ciclo da poda à colheita permitiu a caracterização das cultivares mais precoces: Precocinho (87,5 dias) e a nectarineira Sun Blaze (95,5 dias). As mais tardios foram: Diamante Mejorado (126,5 dias) e CP 951 C (120 dias). As cultivares Turmalina (20,2 kg planta-1), Conserva 693 (20,75 kg planta-1) e Aurora 1 (15,65 kg planta-1) foram as mais produtivas .

A Database of >20 keV Electron Green's Functions of Interplanetary Transport at 1 AU

We use interplanetary transport simulations to compute a database of electron Green's functions, i.e., differential intensities resulting at the spacecraft position from an impulsive injection of energetic (>20 keV) electrons close to the Sun, for a large number of values of two standard interplanetary transport parameters: the scattering mean free path and the solar wind speed. The nominal energy channels of the ACE, STEREO, and Wind spacecraft have been used in the interplanetary transport simulations to conceive a unique tool for the study of near-relativistic electron events observed at 1 AU. In this paper, we quantify the characteristic times of the Green's functions (onset and peak time, rise and decay phase duration) as a function of the interplanetary transport conditions. We use the database to calculate the FWHM of the pitch-angle distributions at different times of the event and under different scattering conditions. This allows us to provide a first quantitative result that can be compared with observations, and to assess the validity of the frequently used term beam-like pitch-angle distribution.

The study evaluated the leaf nutritional levels of peach and nectarine trees under subtropical climate in order to improve the fertilization practices. The experiment was carried out in São Paulo state University, Botucatu, São Paulo State, Brazil. The experimental design consisted of subdivided plots, in which plots corresponded to cultivars and subplots to the leaf sample periods. The evaluated peach cultivars were: Marli, Turmalina, Precocinho, Jubileu, Cascata 968, Cascata 848, CP 951C, CP 9553CYN, and Tropic Beauty, and that of nectarine was 'Sun Blaze'. The sample periods were: after harvest, plants in vegetative period; dormancy; beginning of flowering and fruiting (standard sample). Results indicated significant variations in the levels of N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn for the sampling period and in N, Ca, Mg, S, B, Fe and Mn levels for the cultivars.

The rare cancer network: ongoing studies and future strategy.

The Rare Cancer Network (RCN) was formed in the early 1990's to create a global network that could pool knowledge and resources in the studies of rare malignancies whose infrequency prevented both their study with prospective clinical trials. To date, the RCN has initiated 74 studies resulting in 46 peer reviewed publications. The First International Symposium of the Rare Cancer Network took place in Nice in March of 2014. Status updates and proposals for new studies were heard for fifteen topics. Ongoing studies continue for cardiac sarcomas, thyroid cancers, glomus tumors, and adult medulloblastomas. New proposals were presented at the symposium for primary hepatic lymphoma, solitary fibrous tumors, Rosai-Dorfman disease, tumors of the ampulla of Vater, salivary gland tumors, anorectal melanoma, midline nuclear protein in testes carcinoma, pulmonary lymphoepithelioma-like carcinoma, adenoid cystic carcinoma of the trachea, osteosarcomas of the mandible, and extra-cranial hemangiopericytoma. This manuscript presents the abstracts of those proposals and updates on ongoing studies, as well a brief summary of the vision and future of the RCN.

Avoin lähdekoodi ohjelmistotalojen näkökulmasta

Tässä diplomityössä tarkastellaan avoimen lähdekoodin hyödyntämistä ohjelmistotalojen kolmen asiantuntijaryhmän näkökulmasta: teknologian edustajien, liiketoiminnan johdon ja lakimiesten. Työssä käydään läpi avoimen lähdekoodin historiaa ja OSI:n avoimen lähdekoodin määritelmä. Työssä esitellään myös neljä yleistä avoimen lähdekoodin lisenssiä: GPL, LGPL, BSD ja MPL. Tekninen näkökulma näkyy, kun työssä käydään läpi avoimen lähdekoodin vahvuudet ja heikkoudet. Suurin osa avoimen lähdekoodin tuotteista ei ole vielä tarpeeksi kehittyneitä kaupalliseen käyttöön, mutta joukosta löytyy myös muutama todellinen vaihtoehto. Työssä esitellään viisi tunnettua lähdekoodin tuotetta: Linux, Apache, MySQL, Perl ja PHP. Avoimen lähdekoodin mahdollistamat ansaintamallit tuovat esiin liiketoiminnan johdon kiinnostuksen kohteen. Työssä esitellään viisi yritystä, jotka ovat onnistuneet hyödyntämään näitä liiketoiminnan malleja: Red Hat, VA Software, JBoss, IBM ja Sun Microsystems. Juridisesta näkökulmasta suurin riski avoimen lähdekoodin tuotteiden käytössä on kolmansien osapuolien immateriaalioikeuksien loukkaaminen. Lähes kaikki avoimen lähdekoodin ohjelmistot on lisensoitu siten, etteivät ne anna minkäänlaista takuuta tai ota vastuuta. Työssä käsitellään myös sitä, kuinka avoimen lähdekoodin aiheuttamia riskejä vastaan voidaan suojautua. Työn tuloksena syntyy päätösprosessi, jota voidaan käyttää apuna tehdessä lopullista päätöstä avoimen lähdekoodin ohjelmiston käytöstä.

Activating mutations of STAT5B and STAT3 in lymphomas derived from γδ-T or NK cells.

Lymphomas arising from NK or γδ-T cells are very aggressive diseases and little is known regarding their pathogenesis. Here we report frequent activating mutations of STAT3 and STAT5B in NK/T-cell lymphomas (n=51), γδ-T-cell lymphomas (n=43) and their cell lines (n=9) through next generation and/or Sanger sequencing. STAT5B N642H is particularly frequent in all forms of γδ-T-cell lymphomas. STAT3 and STAT5B mutations are associated with increased phosphorylated protein and a growth advantage to transduced cell lines or normal NK cells. Growth-promoting activity of the mutants can be partially inhibited by a JAK1/2 inhibitor. Molecular modelling and surface plasmon resonance measurements of the N642H mutant indicate a marked increase in binding affinity of the phosphotyrosine-Y699 with the mutant histidine. This is associated with the prolonged persistence of the mutant phosphoSTAT5B and marked increase of binding to target sites. Our findings suggest that JAK-STAT pathway inhibition may represent a therapeutic strategy.

Lentoaseman terminaalirakennuksen energiankäyttö ja sisäilmasto

Diplomityössä tarkasteltiin lentoaseman terminaalirakennuksen energia- ja ainevirtoja sekä sisäilman ominaisuuksia. Esimerkkikohteena oli Helsinki-Vantaan lentoaseman keskiterminaalirakennus, jonka 1. ja 2. rakennusvaiheen ulkovaippa muodosti taserajan. Taseen ulkopuolisista tekijöistä tarkasteltiin jäähdytysenergian tuotantoa ja ulkoilman laatua. Työn yhtenä tavoitteena oli muodostaa rakennukselle energiatase. Taseen avulla saatiin tietoa energian jakautumisesta eri toimintoihin ja löydettiin tekijät, joita suunnittelussa tulee painottaa. Terminaalin lähiympäristössä tutkittiin ulkoilman laatua mittausten avulla. Mittaustietoja käytetään apuna tulevaisuuden ilmanottosuunnittelussa. Työssä tarkasteltiin energia- ja ainevirtoina lämpö-, jäähdytys- ja sähköenergian sekä veden ostoa, tuotantoa ja kulutusta sekä prosessointia. Terminaalin lämpötarpeesta hieman yli puolet katettiin kaukolämmöllä. Loput noin 45 % lämpöenergiasta saatiin ns. ilmaisenergioista. Näistä merkittävimmäksi havaittiin sähkölaitteiden luovuttama lämpömäärä. Lämpöhäviöiden kannalta merkittäviä energiavirtoja olivat ilmanvaihdon ja vuotoilmojen kautta siirtyvät energiavirrat, joiden osuuden todettiin olevan noin 80 % terminaalin kokonaislämpöhäviöistä. Vaipan lämmöneristyskyky ja kyky absorboida auringon säteilyä todettiin hyviksi. Tulevaisuudessa tärkeitä suunnittelunäkökohtia tulevat olemaan ilmanvaihdon ja vuotoilman kautta siirtyvien energiavirtojen hallinta sekä sähköenergian ominaiskulutuksen pienentäminen. Ulkoilma todettiin mittauksin hyvätasoiseksi. Lento- ja maaliikenteen päästöarvot olivat lähellä toisiaan ja selvästi ohjearvoja alemmalla tasolla. Päästöjen sijaintiin vaikuttivat liikennemääriä enemmän tuuliolosuhteet. Tulevaisuudessa tuloilma voidaan johtaa terminaaliin yhtä hyvin joko lento- tai maaliikenteen puolelta.

Ohjelmistoarkkitehtuurien vertailu ja valinta monimediatuotteelle. CASE: AVO

Työn tavoitteena oli tutkia ja vertailla komponenttipohjaisia ohjelmistoarkkitehtuureita (Microsoft .NET ja J2EE). Työn tarkoituksena oli valita ohjelmistoarkkitehtuuri uudelle neuroverkkopohjaiselle urasuunnittelupalvelulle. Tässä työssä selvitettiin myös, miten luodaan kansainvälistettäviä ja lokalisoitavia sovelluksia, sekä kuinka Web-, Windows-, mobiili-, puhe- ja Digi-TV -käyttöliittymät soveltuvat uudelle urasuunnittelupalvelulle. Tutkimustyössä käytettiin alan kirjallisuutta, Microsoftin ja Sun Microsystemsin Web-sivuja. Tutkimustyössä analysoitiin Microsoft Pet Shop- ja Sun Microsystemsin Java Pet Store -esimerkkisovellusten suorituskykyvertailua. Analyysituloksiin perustuen urasuunnittelupalvelussa suositellaan käytettäväksi J2EE-arkkitehtuuria. Uudelle urasuunnittelupalvelulle toimenpide-ehdotus on komponenttipohjainen järjestelmä Web-, puhe- ja Digi-TV -käyttöliittymillä ja personoidulla sisällöllä. Järjestelmä tehdään viisivaiheisena hankkeena, johon sisältyy pilottitestejä. Uuteen urasuunnittelupalveluun liitetään mukaan opiskelijat, oppilaitokset ja työnantajat sekä asiantuntijoita neuroverkon opetusdatan määrittämiseen. Palvelu perustuu integroituun tietokantaan. Eri osajärjestelmissä tuotettua tietoa voidaan hyödyntää kaikkialla urasuunnittelupalvelussa.
