Mapeamento de semeaduras de soja (Glycine max (L.)Merr.) mediante dados MODIS/Terra E TM/Landsat 5: um comparativo

O objetivo deste trabalho foi comparar mapeamentos de semeadura da cultura da soja na região oeste do Paraná, realizados com imagens MODIS/Terra e TM/Landsat 5. Primeiramente, construiu-se máscara de referência, considerando seis imagens TM ao longo do ciclo da cultura, utilizando-se dos algoritmos Paralelepípedo e MaxVer com posterior análise visual. As imagens MODIS foram classificadas com o algorítimo Paralelepípedo, em quatro passagens referentes ao pico vegetativo. O desempenho das classificações foi avaliado por meio de Matrizes de Erros, calculadas pela análise de 100 pontos amostrais (soja ou não-soja), aleatoriamente distribuídos em cada um dos oito municípios da área de estudo. Os principais resultados mostraram que a Exatidão Global (EG) e o Índice Kappa (IK), que variaram entre 0,55 e 0,80, em ambos os sensores, são considerados bons a muito bons. Quando EG e IK dos sensores TM e MODIS foram comparados, não se encontrou diferença significativa. O mapeamento da soja utilizando o sensor MODIS produziu 70% de confiabilidade sob o ponto de vista do usuário. A principal conclusão é a viabilidade de mapear a soja pelo sensor MODIS com as vantagens de que as imagens MODIS têm melhor resolução temporal e são disponibilizadas gratuitamente na Internet.

Strike hard, strike sure - Operation Musketeer : British military planning during the Suez Crisis, 1956

Operation Musketeer, a combined joint Anglo-French operation aimed at regaining control of the Suez Canal in 1956, has received much attention from scholars. The most common approach to the crisis has been to examine the political dimension. The political events that led Prime Minister Anthony Eden’s cabinet to decide to use military force against the wishes of their superior American ally and in the face of American economic pressure and a Soviet threat to attack Paris and London with rockets have been analysed thoroughly. This is particularly the case because the ceasefire and eventual withdrawal were an indisputable defeat of British policy in the Middle East. The military operation not only ruined Prime Minister Eden’s career, but it also diminished the prestige of Britain. It was the beginning of the end, some claim. The British Empire would never be the same. As the consequences of using force are generally considered more important than the military operations themselves, very little attention has been paid to the military planning of Operation Musketeer. The difference between the number of publications on Operation Corporate of the Falklands War and Operation Musketeer is striking. Not only has there been little previous research on the military aspects of Musketeer, the conclusions drawn in the existing works have not reached a consensus. Some historians, such as Correlli Barnett, compare Musketeer to the utter failures of the Tudor landings and Gallipoli. Among significant politicians, Winston Churchill, who had retired from the prime ministership only a year before the Suez Crisis, described the operation as “the most ill-conceived and ill-executed imaginable”. Colin McInnes, a well-known author on British defence policy, represents the middle view when he describes the execution as “far from failure”. Finally, some, like Julian Thompson, the Commander of 3 Commando Brigade during the Falklands War, rate the military action itself as being successful. The interpretation of how successful the handling of the Suez Crisis was from the military point of view depends very much on the approach taken and the areas emphasised in the subject. Frequently, military operations are analysed in isolation from other events. The action of a country’s armed forces is separated from the wider context and evaluated without a solid point of comparison. Political consequences are often used as validated criteria, and complicated factors contributing to military performance are ignored. The lack of comprehensive research on the military action has left room for an analysis concentrating on the military side of the crisis.

Modelo de simulação de secagem de produtos agrícolas usando entalpia do ar constante

A simulação matemática de secagem de produtos agrícolas teve seu auge nas décadas de 1960 e 1970, com destaque para os modelos de Thompson e de Michigan. Entretanto, nenhum deles abordou a condição de entalpia constante do ar de secagem durante o processo, limitando-se a conferir se a umidade relativa do ar não excedia 100%. Estudos conduzidos na Universidade Estadual de Maringá permitiram concluir que os balanços de energia e de massa de um processo de secagem estão incluídos no uso da mesma entalpia do ar durante a secagem, ajustando-se, com ela, a umidade absoluta do ar em função da umidade removida do produto. Com essa nova razão da mistura do ar e com a entalpia constante, avalia-se a nova temperatura do ar de secagem na saída da camada e, com essas duas propriedades psicrométricas, a umidade relativa do ar. Se ela atingir a condição saturada, encerra-se o processo de secagem naquele tempo, a partir daquela posição. Os resultados obtidos por simulação foram conferidos com resultados experimentais de secagem de milho em camadas fixas, com elevada concordância entre eles.

Siirtomaasodasta sisäisen turvallisuuden operaatioon : Sir Robert Thompsonin periaatteet Britannian operaatioissa Malaijilla ja Pohjois-Irlannissa

Sir Robert Thompson määritti vuonna 1966 julkaistussa kirjassaan Defeating Communist Insurgency viisi vastakumoukselliselle sodankäynnille keskeistä periaatetta, jotka ovat: - Hallituksella tulee olla selkeä poliittinen tavoite. - Hallituksen täytyy toimia lainmukaisesti. - Hallituksella pitää olla kaikille toimijoilleen yhteinen yleissuunnitelma ja suunnittelu. - Hallituksen tulee asettaa painopiste poliittisen kumouksellisuuden, ei sissien voittamiseen. - Kumouksellisen sodan ollessa sissisodan vaiheessa, hallituksen tulee turvata ensimmäisenä omat tukialueensa Thompsonin periaatteet pohjautuvat hänen kokemuksiinsa Malaijin kriisin aikana 1948 – 60 ja ne siirtyivät osaksi ensimmäisiä brittiläisiä vastakumouksellisen sodankäynnin ohjesääntöjä, jotka julkaistiin vuonna 1969. Samana vuonna alkoi Pohjois-Irlannin konflikti (1969 – 98). Tutkimuksen tavoitteena on selvittää miten Thompsonin periaatteita toteutettiin ne pääosin synnyttäneessä Malaijin kriisissä ja Pohjois-Irlannin konfliktissa. Tutkimuskysymyksiä ovat: Mitä Thompsonin periaatteet tarkoittavat ja miten ne ovat ilmenneet brittiläisessä ohjesääntökirjallisuudessa? Mikä periaatteiden toteutuksessa yhdisti Malaijin ja Pohjois-Irlannin konflikteja? Mitä eroja periaatteiden toteuttamisessa oli konfliktien välillä? Mitkä tekijät aiheuttivat keskeiset erot periaatteiden toteuttamisessa konfliktien välillä?Tutkimuksen käytetty lähdemateriaali koostuu täysin laadullisesta aineistosta. Tutkimusmenetelmänä on käytetty laadullista, teorialähtöistä sisällönanalyysiä Eri lähteitä vertailemalla tehtyä analyysiä on ohjannut Thompsonin määrittämien periaatteiden kehys. Malaijin ja Pohjois-Irlannin konflikteista saatua analysoitua tietoa on verrattu keskenään käyttäen teoriakehystä, ja näin on pyritty löytämään yhtäläisyyksiä ja eroja Thompsonin periaatteiden toteuttamisessa konfliktien välillä. Tutkimuksen kannalta keskeisiä lähdeteoksia ovat: Sir Robert Thompson: Defeating Communist Insurgency, David McKittrick ja David McVea: Making Sense of the Troubles, Magne Haugseng: The Tightening Grip: Northern Ireland – The Military and 35 Years of Terror. Tutkimuksen kannalta keskeisiä lähdeasiakirjoja ovat Britannian asevoimien Pohjois-Irlannin konfliktista kirjoittama tutkimusraportti Operation Banner - An Analysis of Military Operations in Northern Ireland ja Riley Sunderlandin RAND-tutkimuslaitokselle vuonna 1964 laatimat Malaiji-raportit. Keskeisin ohjesääntölähde oli Britannian asevoimien vuosina 1969 – 70 julkaisema kolmiosainen vastakumouksellisen sodankäynnin ohjesääntö Land Operations Volume III Counter Revolutionary Operations. Tutkimuksessa havaittiin, että Britannian hallituksella oli molemmissa operaatioissa selkeät tavoitteet. Molemmissa operaatioissa hätätilavaltuudet laadittiin mahdollistamaan asevoimille ja poliisille laajat toimivaltuudet. Tästä huolimatta molemmissa operaatioissa tapahtui turvallisuusjoukkojen väärinkäytöksiä. Pohjois-Irlannin väärinkäytöksiä on tuotu selkeämmin esille PIRA:n propagandan ja tiedotusvälineiden läsnäolon takia. Kummassakaan operaatiossa ei ole ollut yhtä selkeää suunnitelmaa, vaan sarja erilaisia suunnitelmia. Malaijilla kaikkien toimijoiden yhteinen suunnittelu toimi koska sitä varten luotiin organisaatiorakenne. Pohjois-Irlannissa yhteisen suunnittelun periaatetta ei toteutettu poliitikkojen haluttomuuden takia. Sekä Malaijilla että Pohjois-Irlannissa toiminnan kohdentaminen kumouksellisuuteen toteutettiin häiritsemällä kumouksellisen vastustajan huoltoa. Malaijilla kumouksellisuuden oikeutusta heikennettiin myös muilla keinoilla kuten yhteiskunnallisia oloja kehittämällä sekä käynnistämällä Malaijin itsenäistymiskehitys. Kummassakaan operaatiossa hallituksen tukialueet eivät olleet vakavasti uhattuna. Keskeinen erottava tekijä operaatioiden välillä johtui tapahtumapaikasta ja – ajasta. Vastustajana PIRA oli kehittyneempi ja se kykeni muuttamaan toimintaansa vastaamaan muutoksia turvallisuusjoukkojen toiminnassa.

Corticolous green algae from tropical forest remnants in the northwest region of São Paulo State, Brazil

The algae inhabit a wide variety of terrestrial environments and substrates; however the taxonomic knowledge for tropical regions is still scarce. This survey was conducted in ten forest remnants in São Paulo State where visible growths of algae and bryophytes were collected and studied for the main algal components of the communities. Results reveal the occurrence of nine species of green algae, distributed through the class Trebouxiophyceae (one species), Charophyceae (one species) and Ulvophyceae (seven species). Desmococcus olivaceus (Persoon ex Archerson) J. R. Laundon and Printzina effusa (Krempelhüber) Thompson & Wujek are new records for Brazil. The most frequent organisms found in the areas pertain to Trentepohliales that is mainly represented by Trentepohlia species. On the basis of results found, it is recommended that such communities receive more attention in future investigations to improve the knowledge about this important group of primary producers.

The effects of surgery on gastrointestinal motor activity

Gastrointestinal surgical procedures have the potential to disrupt motor activity in various organs of the gastrointestinal tract or, indeed, throughout the entire alimentary canal. Several of these motor effects have important clinical consequences and have also served to advance our understanding of the regulation of gastrointestinal motor activity. This review will focus, in particular, on the effects of surgery on the small intestine, and will attempt to emphasize the implications of these studies for our understanding of small intestinal motility, in general.

Immunophenotype of hematopoietic stem cells from placental/umbilical cord blood after culture

Identification and enumeration of human hematopoietic stem cells remain problematic, since in vitro and in vivo stem cell assays have different outcomes. We determined if the altered expression of adhesion molecules during stem cell expansion could be a reason for the discrepancy. CD34+CD38- and CD34+CD38+ cells from umbilical cord blood were analyzed before and after culture with thrombopoietin (TPO), FLT-3 ligand (FL) and kit ligand (KL; or stem cell factor) in different combinations: TPO + FL + KL, TPO + FL and TPO, at concentrations of 50 ng/mL each. Cells were immunophenotyped by four-color fluorescence using antibodies against CD11c, CD31, CD49e, CD61, CD62L, CD117, and HLA-DR. Low-density cord blood contained 1.4 ± 0.9% CD34+ cells, 2.6 ± 2.1% of which were CD38-negative. CD34+ cells were isolated using immuno-magnetic beads and cultured for up to 7 days. The TPO + FL + KL combination presented the best condition for maintenance of stem cells. The total cell number increased 4.3 ± 1.8-fold, but the number of viable CD34+ cells decreased by 46 ± 25%. On the other hand, the fraction of CD34+CD38- cells became 52.0 ± 29% of all CD34+ cells. The absolute number of CD34+CD38- cells was expanded on average 15 ± 12-fold when CD34+ cells were cultured with TPO + FL + KL for 7 days. The expression of CD62L, HLA-DR and CD117 was modulated after culture, particularly with TPO + FL + KL, explaining differences between the adhesion and engraftment of primary and cultured candidate stem cells. We conclude that culture of CD34+ cells with TPO + FL + KL results in a significant increase in the number of candidate stem cells with the CD34+CD38- phenotype.

Modulation of store-operated Ca2+ entry by cyclic-ADP-ribose

Store-operated Ca2+ entry plays an important role in Ca2+ homeostasis in cells but the mechanisms of control of these channels are not completely understood. We describe an investigation of the role of the CD38-cyclic-ADP-ribose (cADPR)-ryanodine-channel (RyR) signaling pathway in store-operated Ca2+ entry in human smooth muscle. We observed that human myometrial cells have a functional store-operated Ca2+ entry mechanism. Furthermore, we observed the presence of transient receptor potential 1, 3, 4, 5, and 6 ion channels in human myometrial cells. Store-operated Ca2+ transient was inhibited by at least 50-70% by several inhibitors of the RyR, including ryanodine (10 µM), dantrolene (10 µM), and ruthenium red (10 µM). Furthermore, the cell permeable inhibitor of the cADPR-system, 8-Br-cADPR (100 µM), is a potent inhibitor of the store-operated entry, decreasing the store operated entry by 80%. Pre-incubation of cells with 100 µM cADPR and the hydrolysis-resistant cADPR analog 3-deaza-cADPR (50 µM), but not with ADP-ribose (ADPR) leads to a 1.6-fold increase in the store-operated Ca2+ transient. In addition, we observed that nicotinamide (1-10 mM), an inhibitor of cADPR synthesis, also leads to inhibition of the store-operated Ca2+ transient by 50-80%. Finally, we observed that the transient receptor potential channels, RyR, and CD38 can be co-immunoprecipitated, indicating that they interact in vivo. Our observations clearly implicate the CD38-cADPR-ryanodine signaling pathway in the regulation of store-operated Ca2+ entry in human smooth muscle cells.

Comparative quantification of umbilical cord blood CD34+ and CD34+ bright cells using the ProCount™-BD and ISHAGE protocols

The total number of CD34+ cells is the most relevant clinical parameter when selecting human umbilical cord blood (HUCB) for transplantation. The objective of the present study was to compare the two most commonly used CD34+ cell quantification methods (ISHAGE protocol and ProCount™ - BD) and analyze the CD34+ bright cells whose 7-amino actinomycin D (7AAD) analysis suggests are apoptotic or dead cells. Twenty-six HUCB samples obtained at the Placental Blood Program of New York Blood Center were evaluated. The absolute numbers of CD34+ cells evaluated by the ISHAGE (with exclusion of 7AAD+ cells) and ProCount™ (with exclusion of CD34+ bright cells) were determined. Using the ISHAGE protocol we found 35.6 ± 19.4 CD34+ cells/µL and with the ProCount™ method we found 36.6 ± 23.2 CD34+ cells/µL. With the ProCount™ method, CD34+ bright cell counts were 9.3 ± 8.2 cells/µL. CD34+ bright and regular cells were individually analyzed by the ISHAGE protocol. Only about 1.8% of the bright CD34+ cells are alive, whereas a small part (19.0%) is undergoing apoptosis and most of them (79.2%) are dead cells. Our study showed that the two methods produced similar results and that 7AAD is important to exclude CD34 bright cells. These results will be of value to assist in the correct counting of CD34+ cells and to choose the best HUCB unit for transplantation, i.e., the unit with the greatest number of potentially viable stem cells for the reconstitution of bone marrow. This increases the likelihood of success of the transplant and, therefore, the survival of the patient.
