Nutritional composition and phenolic compounds and nitrate content in eatable vegetables obtained by conventional and certified organic grown culture
No full textThe aim of this work was to analyse some nutritional characteristics in eatable vegetables obtained by conventional and organic grown culture, focusing on vegetable parts that are generally rejected by consumers. Samples of Chinese cabbage (Brassica rapa (syn. B. campestris) spp. pekinensis)) and maize (Zea mays L.) had been analysed under raw conditions and after thermal treatment in order to test modifications in protein, lipids, carbohydrate, phenol, nitrate content and dry weight. According to our results, thermal
treatment modified some characteristics. Even if for most parameters significant differences between foods obtained by the two cultivation procedures had not been observed, in organic samples a higher concentration of nitrate was found. Furthermore, domestic processing, such as cooking in boiling water, seems to have a dramatic effect on phenolic content on both kinds of food, and, as a consequence, on antioxidant activity
Effect of spermidine on ornamental bromeliad cultured in vitro
No full textPlants of the ornamental bromeliad, Aechmea blanchetiana (Baker) L.B. Smith obtained from seeds germinated in vitro, were treated with spermidine (Spd) at various concentrations (0, 10, 50 and 250 μM) or in the presence of 1.07 mM α-naphthaleneacetic acid (NAA) + 22.20 mM 6-benzyladenine (BA) or 0 mM NAA + 0 mM 6-BA for shoot induction and 0, 1.07 and 5.37 mM of NAA for root induction. The number of shoots, fresh and dry weight of shoots on shoot induction and fresh and dry weight of shoots and roots on root induction, and activity of peroxidases were evaluated. Polyamine Spd was not effective on shooting induction, rooting, mass accumulation of fresh and dry weight and had no influence on the activity of the enzyme peroxidase, and had a deleterious effect on dry matter accumulation in the treatment for shooting induction. Spd improved the qualitative and quantitative responses of in vitro rhizogenesis of A. blanchetiana as compared to the free polyamine medium. Peroxidase activity was higher in leaves of plants subjected to shoot induction, with 6-BA+NAA. The exogenous spermidine did not have effect on peroxidase activity

Endogenous and exogenous polyamines in the organogenesis in Curcuma longa L.
No full textThe present work evaluated the development of different Curcuma longa L. explants (leaves basis, root tips and ancillary buds from rhizome) stimulated by exogenous polyamines, combined with naphtalen-acetic acid (NAA) or with 6-benzyl-aminopurine (BAP), to produce callus and its subsequent
differentiation. The explants, isolated from field plants, were previously subjected to a basic cleaning method and were inoculated onto Murashige and Skoog culture medium (MS) [Murashige, T.S., Skoog, F., 1962. A revised medium for rapid growth and bioassays with tobacco tissue culture. Physiologia Plantarum 15, 473–497] supplemented with NAA (2.0 mg L-1 ). Buds were subjected to different treatments, with or without 5.0 and 10.0 mmol L-1 exogenous polyamines (mixture of putrescine:spermine:spermidine, 1:1:1) combined with NAA. The calluses obtained were transferred into the same
medium, supplemented with the mixture of polyamines combined with BAP, in order to induce plant differentiation. For C. longa, buds were the most efficient explants for callus induction (p < 0.05). The application of exogenous polyamines (5.0 and 10.0 mmol L-1 ) produced the most developed callus, with numerous roots. The medium supplemented with 10 mmol L-1 polyamine mixture, combined with BAP, induced good regeneration, producing vigorous plants and excellent shoot formation.Polyamines addition promoted the formation of callus, roots and leaves, representing an important factor in the determination of indirect organogenesis in C. longa L., and putrescine content may be considered a valuable marker of the differentiation process in this specie, as well as the enzyme peroxidase
Bewusstsein und Realität: die Frage des Idealismus in der frühen indischen Philosophie: [Consciousness and reality: the question of idealism in the early Indian philosophy]
No full textThe lecture was presented before the Gesellschaft für Philosophische Praxis, upon the invitation of Dr. Gerd Achenbach, founder and director of GPP (August 16, 2019).
Delivered in German, it was entitled Bewusstsein und Realität: die Frage des Idealismus in der frühen indischen Philosophie (Consciousness and Reality: the Question of Idealism in the early Indian Philosophy). There were about 40 people in attendance, mostly from the circle of Dr. Achenbach.
I owe thanks to Dr. Achenbach and his industrious assistant, Laura V. Adrian, who spent the three days prior to the talk translating my lecture and preparing me to deliver it in German. An audio recording (in German) is also available in DOOR.Not peer reviewedlectur

GPP user`s guide - a general-purpose postprocessor for wind turbine data analysis
No full textGPP (pronounced {open_quotes}jeep{close_quotes}) is a General-Purpose Postprocessor for wind turbine data analysis. The author, a member of the Wind Technology Division (WTD) of the National Renewable Energy Laboratory (NREL), developed GPP to postprocess test data and simulation predictions. GPP reads data into large arrays and allows the user to run many types of analyses on the data stored in memory. It runs on inexpensive computers common in the wind industry. One can even use it on a laptop in the field. The author wrote the program in such a way as to make it easy to add new types of analyses and to port it to many types of computers. Although GPP is very powerful and feature-rich, it is still very easy to learn and to use. Exhaustive error trapping prevents one from losing valuable work due to input errors. GPP will, hopefully, make a significant impact on engineering productivity in the wind industry
