High pressure liquid chromatography was used to demonstrate that chelation of Mg(2+) into protoporphyrin IX precedes methylation in isolated greening etioplasts from cucumber (Cucumis sativus L. var. Beit Alpha) cotyledons. Mg-protoporphyrin IX synthesized in vitro from protoporphyrin IX, Mg(2+), and ATP or exogenous Mg-protoporphyrin IX could serve as substrates for the methylation step. In ei...

Detached cucumber (Cucumis sativus L. var. Beit Alpha) cotyledons incubated in darkness with 5-aminolaevulinic acid and either 16O2 air (control) or 18O2 in N2 accumulated protochlorophyllide. This was converted into methyl phaeoporphyrin alpha 5 and analysed by mass spectrometry. The molecular ion of the methyl phaeoporphyrin alpha 5 derived from the 18O2 incubation was 2 mass units greater th...

Additional Index Words. Cucumis sativus L., greenhouse, protected culture, beit alpha cucumber Abstract. The Beit Alpha (BA) cucumber is a new commodity for the Florida greenhouse industry. In past trials, BA cultivar production and quality were compared to traditional ‘Dutch’ or European cucumber cultivars. The cv. Sarig, a BA-type, produced three times more yield than the Dutch-type cv. Kalun...

Background: Neurological complications of Influenza A (H1N1) pdm09 in adults are rarely reported in the literature. The aim of this study is to report a case of Influenza A (H1N1) pdm09 acute necrotizing encephalitis (ANE) and another case of acute hemorrhagic leukoencephalopathy (AHLE) and to review the neurological complications of this disorder in adults. Methods: We conducted a search on Me...

studying the prophet’s methods of interaction with his opponents is a need nowadays. through these procedures, we can be aware of the best ways to penetrate into others hearts and introduce religious ideas (instructions). on the other hand, we can consider ahle- ketab including jews, christians and some other religious groups like sabe’in and magus and pagans including idol and star worshipers,...

BACKGROUND Adverse health effects caused by pesticide exposure have been reported in occupied Palestinian territory and the world at large. The objective of this paper is to compare patterns of pesticide use in Beit-U'mmar village, West Bank, between 1998 and 2006. METHODS We studied two populations in Beit-U'mmar village, comprised of: 1) 61 male farmers and their wives in 1998 and 2) 250 ma...

Breast cancer must be detected early to reduce the mortality rate. Ultrasound images can make it easier for clinician diagnose cases of dense breasts. This study presents a deep vision transformer-based approach predicting breast malignancy scores from ultrasound images. In particular, various state-of-the-art transformers such as BEiT, CaiT, Swin, XCiT, and Vis-Former are adapted trained extra...

In this paper the approach to problem solving using societies of agents is discussed. Al-beit being a very promising topic in Arti-cial Intelligence, it seems to lack strong theoretical and methodological foundations and easy-to-use implemented systems in order to prove its usefulness and adequacy. This is the reason a methodology for problem solving based on societies of agents is presented. T...
