Modelling evapotranspiration of soilless cut roses "Red Naomi" based on climatic and crop predictors

Original PaperThis study aimed to estimate the daily crop evapotranspiration (ETc) of soilless cut ‘Red Naomi’ roses, cultivated in a commercial glass greenhouse, using climatic and crop predictors. A multiple stepwise regression technique was applied for estimating ETc using the daily relative humidity, stem leaf area and number of leaves of the bended stems. The model explained 90% of the daily ETc variability (R2 = 0.90, n = 33, P < 0.0001) measured by weighing lysimeters. The mean relative difference between the observed and the estimated daily ETc was 9.1%. The methodology revealed a high accuracy and precision in the estimation of daily ETcinfo:eu-repo/semantics/publishedVersio

Trajtimi i Tregtisë në Shërbime sipas Marrëveshjes së Tregtisë së Lirë Kosovë-Turqi

Qeveria e Kosovës ka nënshkruar një marrëveshje të tregtisë së lirë të mallrave me Turqinë, në Shtator të vitit 2013. Megjithatë, negociatat për nënshkrimin e një marrëveshjeje të tregtisë së lirë në shërbime janë ende në vazhdim e sipër. Kjo është hera e parë që kur Kosova u bë e pavarur në vitin 2008, se Qeveria e Kosovës ka qenë e angazhuar në negociatat tregtare. Marrëveshja e CEFTA-s është marrëveshja e vetme e deritanishme në Kosovë, e cila është negociuar nga UNMIK-u. Mungesa e përvojës në negociatat tregtare krijon sfida për qeverinë, gjatë negocimeve me Turqinë për çështje komplekse, siç është liberalizimi i tregtisë në shërbime. Sfidë tjetër prezentë është krijuar nga negociatat paralele me partnerët e CEFTA-s (për liberalizimin e shërbimeve) dhe Bashkimit Evropian (për krijimin e tregtisë së lirë në mallra). Qëllimi i këtij studimi është t’u ofrojë informacione negociatorëve mbi tregtinë e lirë të shërbimeve me Turqinë, për të formuluar qëndrimin e duhur për negociatat e ardhshme. Punimi fokusohet në aspektet ligjore të masave liberalizuese në mes të Kosovës dhe Turqis

Quem foi que? - Um Desafio à Estatística: Questões de Autoria em "Novas Cartas Portuguesas"

O livro "Novas Cartas Portuguesas" é constituído por uma série de poemas e cartas baseados na história da freira Mariana Alcoforado. Para o estudo efectuado foram escolhidos treze textos em prosa, tendo a escolha destes ficado a dever-se ao facto de ser necessário comparar textos de autoria "desconhecida" com textos de autoria conhecida, para deste modo se estabelecerem comparações e assim se chegar a alguma conclusão sobre os autores dos textos desconhecidos. Como das três autoras em causa apenas Maria Teresa Horta tem poesia publicada, tal facto levou-nos a supor que os poemas que figuram nas Novas Cartas são de sua autoria, eliminando-se assim do estudo os poemas. Na escolha dos textos a estudar também se teve em consideração a hipótese, por nós assumida, de que as três autoras se apresentaram e se despediram; como tal, foram incluídas no estudo as três "Primeiras Cartas" e as três "Cartas Últimas"; note-se que a "Primeira Carta Última" é constituída por três partes distintas que se supôs serem da mesma autora

The Contribution of Universities to Growth: Empirical Evidence for Italy

New entrepreneurial ventures may represent a viable and effective mechanism to transform academic knowledge into regional economic growth. We test this notion for the Italian provinces between 2001 and 2006. We evaluate three outputs of academic activities: teaching, research and Intellectual Property Rights (IPR) activities management. New ventures may be able to transform the mentioned outputs into improved economic performance. The findings show that the effects of academic outputs on provincial economic growth (all sectors) are appreciable when they are associated with sustained entrepreneurial activities in the province. It suggests that academic inquiry may provide new ventures with valuable commercial opportunities overseen by established companies.

Institutional Change and Academic Patenting: French Universities and the Innovation Act of the 1999.

Recent empirical work in the field of university-industry technology transfer has stressed the importance of IPR-related reforms and university patenting has major forces behind the success of US high-tech industry. European policy-makers have been tempted to explain the poorer technological performance of their countries with the lower propensity of their academic institutions to get engaged in patenting and commercializing their research results. As a consequence, a number of measures have been taken to promote academic awareness of IPRs, as part of more comprehensive policies in favour of academic commercialization and entrepreneurship. This paper explores university patenting, and the related policies, in France. We provide evidence that university patenting in that countries has been underestimated by policy-makers’ perceptions: French academic scientists are in fact responsible for no less than 3% of patents by French inventors at the European Patent Office. However, only 10% of academic-invented patents are owned by domestic universities, with the remainder assigned both to firms and to Public Research Organizations (PROs). We then explore the impact of the Innovation Act, passed in France in 1999. We find that the Act has significantly increased the likelihood an academic patent to be assigned to a university rather than to a business company. We also find, that the opening of a technology transfer office in a university appears to have a stronger and more significant impact than the Act on the decision of universities to retain IPRs over their scientists’ discoveries.

Domínios de Atracção e Velocidades de Convergência

Gomes e Pestana (Nonstandard domains of attraction and rates of convergence. New perspectives in theoretical and applied statistics, Wiley Ser. Prob. Math. Statistics, 1987) mostraram que o comportamento pré-assintótico, em valores extremos ocorre em grande variedade de situações e encontraram uma explicação: o domínio de atracção de uma lei estável pode ser particionado num ''domínio de atracção standard`` - em que as constantes de atracção são da forma A n^(1/alpha), onde alpha, é o índice de atracção da estável -, e num domínio de atracção não-standard, em que as constantes de atracção são necessariamente da forma L(n)n^(1/alpha) com L(n), de variação lenta, convergindo para 0, ou infinito. Neste trabalho exploramos a questão da qualidade da aproximação nas caudas no domínio de atracção não standard de uma estável simétrica, impondo um controle extra na sua variação, com um parâmetro de segunda ordem.FCT/POCTI/FEDER, Projecto VEXTRE e programa PRODEP, Acção 5.

Effects of Chronis Consumption of Caffeine on Memory for Prose in Young and Elderly Adults

Caffeine is one of society\u27s most widely used central nervous system stimulants. Most studies involving caffeine and memory have tested the recall of young subjects following acute administration of caffeine. This study was designed to determine the effects of chronic use of caffeine on memory for prose in young and elderly adults. Forty-nine young and forty-nine elderly subjects read four expository prose passages from the computer screen and orally recalled each story Recalls were tape recorded and later scored for presence of idea units Chronic consumption of caffeine had no significant effect on recall of prose passages. It is speculated that this result may be due to tolerance effects which develop with habitual caffeine consumption

Effects of Pre- and Post- Trial Caffeine Treatment on Memory for Prose

Caffeine is a central nervous system stimulant which is considered part of the normal diet. One approach to understanding whether ingestion of caffeine influences human cognition is to examine the effects of caffeine on memory. This study examined the effects of caffeine ingested both before and after a prose learning task. Two hundred-forty-five subjects (121 males, 124 females) were divided into two groups. One group received 0, 2, or 4 mg/kg of caffeine before hearing three narrative prose passages. The second group received 0, 2, or 4 mg/kg of caffeine after hearing the prose passages. All subjects returned 24 hours later and wrote their recalls. Caffeine, ingested either before or after the presentation of prose passages, enhanced recall of these passages in females. In males, ingestion of caffeine after presentation of prose passages was detrimental to recall. The present results provided no clear evidence as to the reason for the observed gender differences. Speculation as to possible explanations for gender differences is included in the discussion
