Abstract: the physiological quality of seeds of native species is important to produce healthy saplings and therefore guarantee the success of programs to recover disturbed vegetation. this reinforces the necessity for investigating the physiological quality of those seeds. to evaluate the effects of different drying rates on the germination, moisture content and storability of eugenia involucrata diaspores, mature fruits collected at mogi gua?u, sp, brazil had their epi- and mesocarps removed by washing and were dried at 30, 40 or 50oc until their water content was reduced from 57% (fresh diaspores) to 13% (final drying), totaling six drying levels. in a second experiment, diaspores had their moisture content reduced from 57% to 49%, at 30oc, totaling six drying levels (0h, 1h, 2h, 3h, 4h and 5h), and were kept for 180 days in plastic bags under cold storage. the drying rate had no effect on tolerance to desiccation by e. involucrata diaspores; water contents lower than 51% decreased both germinability and storability. diaspores can be stored for up to 180 days as long as their water content is reduced to 53% and they are kept inside plastic bags under cold storage.

Abstract: The physiological quality of seeds of native species is important to produce healthy saplings and therefore guarantee the success of programs to recover disturbed vegetation. This reinforces the necessity for investigating the physiological quality of those seeds. To evaluate the effects of different drying rates on the germination, moisture content and storability of Eugenia involucrata diaspores, mature fruits collected at Mogi Gua u, SP, Brazil had their epi- and mesocarps removed by washing and were dried at 30, 40 or 50masculineC until their water content was reduced from 57% (fresh diaspores) to 13% (final drying), totaling six drying levels. In a second experiment, diaspores had their moisture content reduced from 57% to 49%, at 30masculineC, totaling six drying levels (0h, 1h, 2h, 3h, 4h and 5h), and were kept for 180 days in plastic bags under cold storage. The drying rate had no effect on tolerance to desiccation by E. involucrata diaspores; water contents lower than 51% decreased both germinability and storability. Diaspores can be stored for up to 180 days as long as their water content is reduced to 53% and they are kept inside plastic bags under cold storage.

Kohoma, Sueli;Maluf, Angela Maria;Bilia, Denise Augusta Camargo;Barbedo, Claudio José;
Revista Brasileira de Sementes , 2006, DOI: 10.1590/S0101-31222006000100010
Abstract: there is an increasing need for investigations of the brazilian native tree species, mainly the physiological quality of their seeds. to evaluate the desiccation tolerance and storability of eugenia brasiliensis seeds, mature fruits collected at mogi-gua?u, sp, brazil and their seeds were removed by washing and were dried at 36oc until their water content was reduced from 48.9% (fresh seeds, wet basis) to 23.6% (final drying), totaling five drying levels. samples of each drying level were stored at 7oc in plastic bags for 270 days. results showed that water content lower than 43.1% decreased both germinability[germination potential] and storability. seeds with 48.9% water content showed 60% germination after 180 days and 19% after 270 days of storage inside plastic bags in a cold chamber. we concluded that e. brasiliensis seeds can be stored for 180 days at 7oc and are intolerant to drying at 36oc.

Abstract:

Flavonoids are among the biggest group of polyphenols, widely distributed in plant-based foods. A plethora of evidence supports the health benefits and value of flavonoids can play in the physiological function treatment and in the prevention of disease particularly in the prevention of degenerative conditions including cancers, cardiovascular and neurodegenerative diseases. Hence, flavonoids represent the active constituents of many dietary supplements and herbal remedies, as well as there is an increasing interest in this class of polyphenols as functional ingredients of beverages, food grains and dairy products. Conversely, various studies have also shown that flavonoids have some drawbacks after oral administration such as stability, bioavailability and bioefficacy. This article reviews the current status of novel nanodelivery systems including nanospheres, nanocaspsules, micro- and nanoemulsions, micelles, solid lipid nanoparticles and nanostructured lipid capsules, successfully developed for overcoming the delivery challenges of flavonoids.

Brazilian Journal of Botany , 2003, DOI: 10.1590/S0100-84042003000200009
Abstract: eugenia pyriformis cambess. ("uvaia"), a tropical tree species from brazil, could be used in forest regeneration programs, arboriculture and for fruit industrial use. however, seed production is not enough to produce seedlings in commercial scale. in this work, when seeds of e. pyriformis were longitudinally or transversally sectioned, high percentage of germination was maintained and even those that had been cut to leave 1/4th of the original seed size have germinated and produced normal seedlings. in a second experiment, seeds were cut into eight parts and at least one of them germinated. our results showed that it is possible to obtain more than one normal seedling from each seed. furthermore, higher germination percentage and normal seedling growth have been obtained when seeds were cut in the longitudinal way.

Abstract: seeds of ocotea corymbosa (meissn.) mez., a species of utility in the recovery of degraded areas and urban arborization, are short-lived under natural conditions. to verify some features of o. corymbosa seed germination, conservation, and natural longevity, seeds were obtained from trees of the region of moji-gua?u, sp, brazil. seed quality was evaluated through germination, vigor and water content, both before and after storage for 30, 60, 90, 120, and 150 days. this storage was carried out under two conditions: a) seeds disposed in paper bags, in the natural environment of the laboratory and b) seeds disposed in punched plastic bags, in a cold chamber (8 ± 2 degrees). germination tests were conducted under four constant temperatures: 20, 25, 30, and 35oc. results showed that o. corymbosa seeds have a natural longevity of about 60 days. we conclude that germination of seeds of o. corymbosa is better at 30oc than 20, 25, or 35oc and also that longevity can be increased to at least 150 days if stored in plastic bag at 8 ± 2oc.
Fracionamento e germina o de sementes de uvaia (Eugenia pyriformis Cambess. - Myrtaceae)
Silva Cristiana V.,Bilia Denise A.C.,Maluf Angela M.,Barbedo Claudio J.
Brazilian Journal of Botany , 2003,
Abstract: Eugenia pyriformis Cambess. (uvaia), espécie arbórea tropical do Brasil, pode ser utilizada em programas de reflorestamento e em áreas urbanas e seus frutos apresentam potencialidade de uso industrial. Contudo, apesar da elevada porcentagem de germina o, a produ o de sementes dessa espécie é insuficiente para produ o de mudas em escala comercial. No presente trabalho, sementes de E. pyriformis foram cortadas longitudinalmente ou transversalmente em duas partes e mantiveram a elevada porcentagem de germina o e de produ o de plantulas normais, mesmo quando a fra o resultante do corte tinha apenas 1/4 da semente. Em um segundo experimento, as sementes foram cortadas em até oito partes e pelo menos uma das fra es de cada semente continuou apresentando germina o. Os resultados mostraram que, através do fracionamento, é possível obter mais de uma plantula normal a partir de cada semente. Os melhores resultados foram obtidos com o corte longitudinal.

Abstract: Este trabalho objetivou estudar aspectos da germina o e do armazenamento de diásporos de Ocotea corymbosa (Meissn.) Mez., bem como estimar sua longevidade natural. Os diásporos foram obtidos de árvores da regi o de Moji-Gua u, SP, em outubro de 1996. Avaliaram-se a porcentagem de germina o, o teor de água e o vigor dos diásporos, antes e após o armazenamento por 30, 60, 90, 120, 150 dias. Este foi realizado sob duas condi es: a) diásporos em sacos de papel, em ambiente de laboratório e b) diásporos em sacos plásticos perfurados, dentro de camara fria (8 ± 2 oC). Os testes de germina o foram, ainda, realizados sob quatro temperaturas constantes: 20, 25, 30 e 35oC. Os resultados mostraram que diásporos de O. corymbosa apresentam longevidade natural próxima a 60 dias. Esta longevidade pode ser ampliada para, no mínimo, 150 dias quando o armazenamento das sementes é realizado dentro de sacos plásticos, em camara fria. A germina o foi favorecida pela temperatura constante de 30oC.
Tourism as an Exit Strategy at Crisis Times  [PDF]
Angela Besana, Anna Maria Bagnasco
Open Journal of Applied Sciences (OJAppS) , 2015, DOI: 10.4236/ojapps.2015.53009
Abstract: The contemporary crisis is giving evidence of failing macroeconomic theories and policies, after decades of focusing on the aggregate domestic demand and the role of the public expenditure. The contemporary crisis has shown the weakness of fiscal policy. With very low interest rates, the monetary policy does not seem to provide an alternative exit strategy out of the crisis, too. In this paper we discuss the hypothesis that GDP can still be a reliable estimate of growth. Nevertheless, at crisis times, only if the focus is on the foreign demand like International Tourism Receipts and Exports, and Exports can be an exit strategy. One component of Exports and International Tourism Receipts are worthy of attention. Thanks to a cluster analysis of per year variations of International Tourism Receipts (ITRs), GDP and Exports (World Bank Database) from 2007 to 2011, average positive variations of GDPs are matching with positive ITRs and Exports for “clusters” of countries. Performances of Europe and USA are worse than China, Brazil, India and South Africa and these continents and countries are separated in two different clusters. This result can be related to an increase of trade in emerging economies more than in mature ones, whose exit out of the crisis is much more demanding. The research confirms that Tourism and Exports are having an impact on the growth at different intensities (Europe and America vs. Asia) at crisis times.
About the Mean Difference of the Inverse Normal Distribution  [PDF]
Giovanni Girone, Angela Maria D’Uggento
Applied Mathematics (AM) , 2016, DOI: 10.4236/am.2016.714130
Abstract: The calculation of the mean difference for the inverse normal distribution can be obtained by a transformation of variable or a hard integration by parts. This paper shows a simpler formula of the mean difference of the inverse normal distribution that highlights the role of the two parameters on the mean difference of the model. It makes it easier to study the relation of the mean difference with the other indexes of variability for the inverse normal distribution.
