Qualidade sensorial e físico-química de uvas finas de mesa cultivadas no submédio São Francisco

O objetivo deste trabalho foi avaliar uvas Vitis vinifera L. das variedades comerciais: Brasil, Benitaka, Itália e Red Globe, quanto às características físico-químicas e sensoriais. Os teores de sólidos solúveis, diâmetro e comprimento das bagas, cujos resultados apresentaram conformidade com os padrões comerciais, foram determinados. A avaliação sensorial foi realizada por meio da Análise Descritiva Quantitativa - ADQ. Foram selecionados e treinados os julgadores que, sob orientação de um líder, estabeleceram os atributos sensoriais capazes de descrever com fidedignidade as características das uvas, conforme se segue: tonalidade de cor, uniformidade de cor, aroma característico, firmeza, gosto doce, gosto amargo, gosto ácido, adstringência, sabor e qualidade global. Constatou-se que as médias obtidas nos atributos tonalidade de cor, uniformidade de cor, firmeza, sabor e qualidade global diferiram estatisticamente dentre as uvas avaliadas e, ainda, que os atributos do sabor, seguido do gosto doce e da tonalidade da cor, apresentaram as correlações mais fortes com a qualidade global, determinantes, portanto, das características sensoriais das uvas.

Water availability predicts forest canopy height at the global scale.

The tendency of trees to grow taller with increasing water availability is common knowledge. Yet a robust, universal relationship between the spatial distribution of water availability and forest canopy height (H) is lacking. Here, we created a global water availability map by calculating an annual budget as the difference between precipitation (P) and potential evapotranspiration (PET) at a 1-km spatial resolution, and in turn correlated it with a global H map of the same resolution. Across forested areas over the globe, Hmean increased with P-PET, roughly: Hmean (m) = 19.3 + 0.077*(P-PET). Maximum forest canopy height also increased gradually from ~ 5 to ~ 50 m, saturating at ~ 45 m for P-PET > 500 mm. Forests were far from their maximum height potential in cold, boreal regions and in disturbed areas. The strong association between forest height and P-PET provides a useful tool when studying future forest dynamics under climate change, and in quantifying anthropogenic forest disturbance.

New product launches are becoming more and more important to companies around the globe. Being first on the market is a good place to be, and it will mostly likely bring the best profits. Gaining that desired position requires a lot of work where cooperation inside as well as outside of the company need to be in line. This thesis discusses launching processes in a pharmaceutical firm. The topic is looked at from supply chain management's point of view where purchasing department's role is emphasized. Additionally, launching strategies related to launches are investigated and the idea of internal alignment is introduced. Moreover, the topic is examined in project and process management perspective; how with the tools of project and process management the launching processes could be improved. The main findings reveal that there are many improvement points in the current launching process. Problems in the areas of information exchange, leadership and internal alignment were discovered yet trust and confidence for the better future compound the interviewees. This study presents what are the most important factors for a successful product launch and how the current processes could be streamlined.

DOHaD et information épigénétique - Enjeux sociétaux [DOhaD and epigenetic information: societal challenges].

The concept of the developmental origins of health and disease (DOHaD) alters our understanding of what constitutes "health" or "disease" intended as chronic, non-communicable diseases, which develop over the life course in high income and emerging countries. It implies a change in paradigm forming a basis for prevention policies across the globe. It also impacts psychological, social, economic, ethical and legal sciences. In line with the unanticipated underpinning epigenetic mechanisms are also the social issues (including public policies) that could be produced by the knowledge related to DOHaD that opens a wide field of inquiry. The information unveiled by epigenetics coupled with information on lifestyle including during the development phase, is of unforeseen nature, raising issues of different nature. Therefore it requires specific attention and research, and a specific support by a pluridisciplinary reflection since the very beginning of its production, to anticipate the questions that might be raised in the future.

The influence of a certain volume of fluid in the lower tear meniscus on intraocular pressure measurements using the non-contact tonometer

Background: Intraocular pressure (IOP) is the pressure inside the eye that helps to maintain the integrity and the suitable form of the ocular globe. Precise and accurate measures of IOP are needed for the diagnosis as well as follow-up of glaucoma. In daily clinical practice, Goldmann applanation tonometer (GAT) and Non-contact tonometer (NCT) are the most common devices for measuring IOP. A close agreement between these methods has been showed, particularly in normotensive patients and a poor agreement, especially when IOP levels are above the normal range. Ophthalmologists have noticed a poor agreement between NCT and GAT, observing that by using NCT and after comparing with GAT, there is an overestimation of IOP readings, and particularly it occurs when the eyes are tearful. Previous studies investigate the effect of tears in Non-contact tonometer readings by the instillation of artificial tears, concluding in one of the studies that the variation was less than 1mmHg and not clinically significant, in contrast with another study which the increases were sadistically significant. Tear menisci are a thin strip of tear fluid located between the bulbar conjunctiva and the eyelid margins. We think that the overestimation of IOP readings using NCT could be due to the presence of a higher volume of tear in the lower tear meniscus which might cause an optical interference in the optoelectronic applanation monitoring system of this deviceObjectives: To research the influence of a certain volume of fluid in the lower tear meniscus on IOP measurements using the NCT in healthy eyes. Moreover, to investigate the agreement between IOP readings obtained by NCT and GAT in the presence and absence of this volume of fluidMethods: The study design will be transversal for diagnostic tests of repeated measures. We will study patients with no ocular pathology and IOP<21mmHg. It will consist in the measurement of IOP using NCT before and after the instillation of COLIRCUSÍ FLUOTEST, used as a volume of fluid in the lower tear meniscus, to observe if there will be differences using the paired t-test. Moreover, we will take IOP measures by GAT in order to know the agreement between these methods after and before the application of these eyedrops, using the ICC (intraclass correlation coefficient) and the Bland-Altmann method

Calculation of radio electrical coverage in Medium-Wave Frequencies

The aim of this project is to accomplish an application software based on Matlab to calculate the radioelectrical coverage by surface wave of broadcast radiostations in the band of Medium Wave (WM) all around the world. Also, given the location of a transmitting and a receiving station, the software should be able to calculate the electric field that the receiver should receive at that specific site. In case of several transmitters, the program should search for the existence of Inter-Symbol Interference, and calculate the field strenght accordingly. The application should ask for the configuration parameters of the transmitter radiostation within a Graphical User Interface (GUI), and bring back the resulting coverage above a map of the area under study. For the development of this project, it has been used several conductivity databases of different countries, and a high-resolution elevation database (GLOBE). Also, to calculate the field strenght due to groundwave propagation, it has been used ITU GRWAVE program, which must be integrated into a Matlab interface to be used by the application developed.

Oceanografia e Química: unindo conhecimentos em prol dos oceanos e da sociedade

The marine environment is certainly one of the most complex systems to study, not only because of the challenges posed by the nature of the waters, but especially due to the interactions of physical, chemical and biological processes that control the cycles of the elements. Together with analytical chemists, oceanographers have been making a great effort in the advancement of knowledge of the distribution patterns of trace elements and processes that determine their biogeochemical cycles and influences on the climate of the planet. The international academic community is now in prime position to perform the first study on a global scale for observation of trace elements and their isotopes in the marine environment (GEOTRACES) and to evaluate the effects of major global changes associated with the influences of megacities distributed around the globe. This action can only be performed due to the development of highly sensitive detection methods and the use of clean sampling and handling techniques, together with a joint international program working toward the clear objective of expanding the frontiers of the biogeochemistry of the oceans and related topics, including climate change issues and ocean acidification associated with alterations in the carbon cycle. It is expected that the oceanographic data produced this coming decade will allow a better understanding of biogeochemical cycles, and especially the assessment of changes in trace elements and contaminants in the oceans due to anthropogenic influences, as well as its effects on ecosystems and climate. Computational models are to be constructed to simulate the conditions and processes of the modern oceans and to allow predictions. The environmental changes arising from human activity since the 18th century (also called the Anthropocene) have made the Earth System even more complex. Anthropogenic activities have altered both terrestrial and marine ecosystems, and the legacy of these impacts in the oceans include: a) pollution of the marine environment by solid waste, including plastics; b) pollution by chemical and medical (including those for veterinary use) substances such as hormones, antibiotics, legal and illegal drugs, leading to possible endocrine disruption of marine organisms; and c) ocean acidification, the collateral effect of anthropogenic emissions of CO2 into the atmosphere, irreversible in the human life time scale. Unfortunately, the anthropogenic alteration of the hydrosphere due to inputs of plastics, metal, hydrocarbons, contaminants of emerging concern and even with formerly "exotic" trace elements, such us rare earth elements is likely to accelerate in the near future. These emerging contaminants would likely soon present difficulties for studies in pristine environments. All this knowledge brings with it a great responsibility: helping to envisage viable adaptation and mitigation solutions to the problems identified. The greatest challenge faced by Brazil is currently to create a framework project to develop education, science and technology applied to oceanography and related areas. This framework would strengthen the present working groups and enhance capacity building, allowing a broader Brazilian participation in joint international actions and scientific programs. Recently, the establishment of the National Institutes of Science and Technology (INCTs) for marine science, and the creation of the National Institute of Oceanographic and Hydrological Research represent an exemplary start. However, the participation of the Brazilian academic community in the latest assaults on the frontier of chemical oceanography is extremely limited, largely due to: i. absence of physical infrastructure for the preparation and processing of field samples at ultra-trace level; ii. limited access to oceanographic cruises, due to the small number of Brazilian vessels and/or absence of "clean" laboratories on board; iii. restricted international cooperation; iv. limited analytical capacity of Brazilian institutions for the analysis of trace elements in seawater; v. high cost of ultrapure reagents associated with processing a large number of samples, and vi. lack of qualified technical staff. Advances in knowledge, analytic capabilities and the increasing availability of analytical resources available today offer favorable conditions for chemical oceanography to grow. The Brazilian academic community is maturing and willing to play a role in strengthening the marine science research programs by connecting them with educational and technological initiatives in order to preserve the oceans and to promote the development of society.

Hospedeiros alternativos de Xanthomonas campestris pv. viticola

Xanthomonas campestris pv. viticola (Xcv), que causa o cancro bacteriano da videira, sobrevive em plantas infectadas, epifiticamente em órgãos da parte aérea e pode ser veiculada em mudas e/ou bacelos infectados. O trabalho teve como objetivo investigar possíveis hospedeiros alternativos do patógeno, visando fornecer subsídios para o manejo da doença. A partir das plantas invasoras Alternanthera tenella, Amaranthus sp., Glycine sp. e Senna obtusifolia com sintomas similares aos do cancro bacteriano da videira, coletadas em parreirais de Juazeiro e Petrolina, no Submédio São Francisco, foram isoladas bactérias semelhantes a Xcv. No entanto, nenhuma bactéria foi isolada de plantas de Commelina benghalensis e Azadirachta indica com sintomas semelhantes. A patogenicidade dos isolados bacterianos obtidos foi confirmada em plantas de A. tenella, Amaranthus sp., Glycine sp., S. obtusifolia e em mudas de videira cv. Red Globe, em condições de casa de vegetação. As plantas invasoras Chamaesyce hirta, Dactyloctenium aegyptium, Eragrostis pilosa e Pilea sp., inoculadas artificialmente com os isolados Xcv1 e UnB1216, também desenvolveram sintomas típicos do cancro bacteriano.

Eurooppalainen näkökulma suomalaiseen kulttuurijohtamiseen ja suomalaiseen yhteiskuntaan sopeutuminen

Tässä tutkielmassa korostuu Euroopan sisäinen kulttuurillinen erilaisuus ja sen vaatimukset Suomessa toimiville monikansallisille organisaatioille. Eurooppalaista johtamista on tutkittu jo vuosikymmenten ajan, mutta erityisesti suomalaisesta, Suomessa työskentelevien eurooppalaisten näkökulmasta ei vastaavaa tutkimusta tiettävästi ole aiemmin tehty. Tutkimuksen tavoitteena on selvittää suomalaisen kulttuurin ja johtajuuden arvoeroja muiden Euroopan Unionin maiden kansalaisten näkökulmasta. Pohjois-Euroopan maista tutkimuksessa on mukana edustajia Ruotsista, Tanskasta ja Hollannista. Keski-Euroopan maista edustusta löytyy Saksasta ja Itävallasta, kun Etelä-Eurooppaa edustavat ranskalaiset ja italialaiset henkilöt. Itäisestä Euroopasta mukana on latvialaisia henkilöitä ja anglo-Euroopasta britannialaisia. Tutkimus kartoittaa tutkimukseen mukaan otettujen maiden yhteisö- ja johtamiskulttuurillisia törmäyskohtia suomalaisen kulttuurin kanssa, jotta Suomessa toimivat monikansalliset työyhteisöt löytäisivät yhä parempia strategioita eurooppalaisen ihmispääoman, eurooppalaisten työntekijöiden ja näiden osaamisen, johtamiseksi ja monikansallisen yhteisön toimivuuden ymmärtämiseksi ja parantamiseksi. Näitä törmäyskohtia tarkastellaan empiirisesti Hofsteden (1984) kulttuuridimensioiden, Housen ym. (1999) GLOBE-tutkimuksen ja Koopmanin ym. (1999) johtajuusulottuvuuksien avulla. Tutkimusaineisto koostuu Internet-pohjaisesta kyselystä, joka suoritettiin keväällä 2010. Siihen osallistui 75 Suomessa työskentelevää Euroopan Unionin kansalaista. Analysointimenetelmänä tutkimuksessa käytetään klusterointia, keskiarvoistuksia, Kruskall Wallisin testiä ja sisällönanalyysiä tukemaan määrällisen analyysin tuloksia ja tuomaan esiin siitä poikkeavia havaintoja. Tutkimuksen ytimessä on johtamiskulttuurilliset erot, joista tehdään laajempaa analyysiä edellä mainituin keinoin. Yhteisökulttuurillisia eroja havainnoidaan tutkimuskyselyyn perustuvien väittämien perusteella tehtyjen histogrammien avulla. Tutkimuksen tulokset osoittavat, että maantieteellinen, uskonnollinen tai poliittinen läheisyys eivät määritä kulttuurillista läheisyyttä tai johda kulttuurilliseen sopeutumiseen. Poliittinen raja kahden naapurin välillä saattaa johtaa saman asian kokemiseen kahdella täysin eri tavalla. Lisäksi tuloksista käy ilmi, että yhteisökulttuurilliset ja johtamiskulttuurilliset arvot eivät välttämättä kulje käsikkäin Suomessa työskentelevien eurooppalaisten näkökulmasta. Yleisinä kulttuurillisina kipukohtina tutkimuksessa nousee esiin suomalaisen kulttuurin sosiaalisuuden ja kommunikaation puutteellisuus, toisaalta suomalaiseen kulttuuriin sopeutumista helpottaa suomalainen rehellisyys ja suoruus. Johtamiskulttuurillisina haasteina eurooppalaiset kokevat suomalaisen tyyppijohtajan kyvyttömyyden riskien ottamiseen ja kannustusmenetelmien puutteet. Tämän lisäksi tutkimuksessa tulee ilmi useita tiettyihin kansallisuuksiin liittyviä törmäyskohtia. Tutkimus on nähtävä tämän hetken kuvauksena. Kulttuuritutkimus sisältää monia tekijöitä, jotka ovat jatkuvassa muutoksessa ja lisäksi hyvin subjektiivisia. Kulttuurijohtajuus merkitsee kuitenkin nyt ja tulevaisuudessa kykyä olla innovatiivinen, joustava ja herkkä sosiaalisille merkityksille.

Harvinaisten metallien talteenotto epäorgaanisista jätevirroista

Taloudellisesti tärkeiden metallien varannot ja tuotanto eivät ole jakautuneet tasaisesti. Maantieteelliset alueet, joilla ei ole omia varantoja ovat riippuvaisia muualta tuoduista raaka-aineista. Euroopan komissio ja USA:n energiaministeriö ovat luokitelleet tietyt metallit kriittisiksi niiden taloudellisen merkittävyyden ja saatavuuteen liittyvien epävarmuustekijöiden johdosta. Tällaisten metallien saatavuutta voitaisiin mahdollisesti parantaa lisäämällä niiden talteenottoa jätteistä. Tutkimuksessa kartoitettiin Euroopan komission kriittiseksi luokittelemien metallien pitoisuuksia eräissä jätevirroissa. Kartoitetut jätteet olivat teollisissa poltto-prosesseissa syntyneitä polttojätteitä, prosessiteollisuuden jätesakkoja ja sähkö- ja elektroniikkajätteitä. Kartoituksen perusteella valittiin lupaavimmat jätteet ja suoritettiin niille talteenottokokeita. Talteenottokokeita suoritettiin kolmelle jätteelle. Yhdestä jätesakasta liuotettiin indiumia rikki- ja suolahapoilla. Kahden eri polttojätteen seoksesta liuotettiin galliumia rikkihapolla. Käytettyjen loisteputkien käsittelyprosessista peräisin olleesta sakasta liuotettiin maametalleja rikki- ja suolahapoilla sekä rikki- ja typpihapon seoksella. Indium liukeni heikosti (korkeintaan 25 %) huoneenlämmössä rikkihapolla. Suolahapolla se liukeni paremmin (68 %). Polttojätteen liuotuskokeissa galliumin talteenottoasteen todettiin riippuvan käytetyn liuottimen määrästä. Loisteputkijätesakasta liukeni yttriumia ja europiumia kaikilla käytetyillä happoliuoksilla noin 70–100 %. Käytetyillä happokonsentraatioilla ei havaittu suuria eroja yttriumin ja europiumin liukoisuuksissa. Näitä metalleja voitaisiin mahdollisesti ottaa talteen tämän tyyppisestä sakasta liuottamalla ne happoliuoksella ja saostamalla oksalaattina. Tarvittaessa liuokset voitaisiin puhdistaa tai metallit erottaa toisistaan neste–nesteuutolla, joka on tärkein maametallien tuotantoon käytetty hydrometallurginen menetelmä.

Thermal comfort indices in individual shelters for dairy calves with different types of roofs

Among the building materials used in rural facilities, roofs are noteworthy for being largely responsible for thermal comfort, influencing the thermal balance within the shelter. This study aimed to evaluate the influence of roof on the Enthalpy (H), Thermal Load of Radiation (TLR), and Black Globe Temperature and Humidity Index (BGHI) in individual shelters for dairy calves. The design was completely randomized with three treatments: Z - zinc tile, AC - asbestos-cement tile and ACW - asbestos-cement tile painted white on the upper side. The averages were compared by the Scott Knott test at 1% probability. The results showed no statistical difference between treatments (P<0.01) and the external environment for H. For TLR, there was statistical difference among all treatments, where ACW showed the lowest TLR, 489.28 W m-2, followed by AC with 506.72 W m-2 and Z with the highest TLR, 523.55 W m-2. For BGHI, the lowest values were observed for ACW (76.8) and AC (77.4), differing significantly from Z, which obtained the highest value (81.6). The tiles with white paint on the upper side promoted the lowest TLR and the lowest BGHI, favoring the thermal environment in the shelter.

Environmental comfort in constructions for Sindi and Guzera calves in the agreste region of the State of Paraiba, Brazil

The objective of this study was to evaluate the quality of air, bioclimatic indexes of facilities and physiological indices of Guzera and Sindhi calves, reared in climatic conditions of Agreste. The study was conducted at the experimental station of Alagoinha, PB, Brazil, using 16 calves of Sindi and Guzerá races. The average concentration of oxygen (20.85%), ammonia (1.99 ppm), carbon monoxide (<0.01 ppm), methane (0.13 ppm) and hydrogen sulfide (<0.01) within facilities, were within the limits established by the Brazilian and international standards, for both animals and workers. The bioclimatic index of temperature and humidity and the temperature of the black globe and humidity index were within the thermal comfort zone for cattle in most of the experimental period, the mean values of respiratory frequency (26.0 min mov-1) and skin temperature (32.3 °C) were higher in the hottest time of the day (1 pm) and rectal temperature (39.3 ºC) in the late afternoon (5 pm), but remained within normal ranges for the studied races. The races have good adaptability to climatic conditions in the region of the Paraibano Agreste, Brazil.

Adjust of regression models to estimate the rectal temperature of broilers for the first 14 days of life

The broiler rectal temperature (t rectal) is one of the most important physiological responses to classify the animal thermal comfort. Therefore, the aim of this study was to adjust regression models in order to predict the rectal temperature (t rectal) of broiler chickens under different thermal conditions based on age (A) and a meteorological variable (air temperature - t air) or a thermal comfort index (temperature and humidity index -THI or black globe humidity index - BGHI) or a physical quantity enthalpy (H). In addition, through the inversion of these models and the expected t rectal intervals for each age, the comfort limits of t air, THI, BGHI and H for the chicks in the heating phase were determined, aiding in the validation of the equations and the preliminary limits for H. The experimental data used to adjust the mathematical models were collected in two commercial poultry farms, with Cobb chicks, from 1 to 14 days of age. It was possible to predict the t rectal of conditions from the expected t rectal and determine the lower and superior comfort thresholds of broilers satisfactorily by applying the four models adjusted; as well as to invert the models for prediction of the environmental H for the chicks first 14 days of life.
