Effect of Cd-containing wood ash on the microflora of coniferous forest humus
2000
The use of wood ash in forestry has been questioned because the cadmium (Cd) concentration of ash, which varies between 1 and 20 mg kg(-1) ash, exceeds the level allowed for fertilizers (3 mg kg(-1)) used in agriculture. To investigate the combined and separated effects of Cd and ash on the forest humus microflora, pumice or wood ash, spiked with a water-soluble (CdCl(2)) or -insoluble (CdO) form of Cd at three levels (0, 400 and 1000 mg kg(-1)), were applied at a fertilization level of 5000 kg ha(-1) in a laboratory microcosm study. The trial consisted of 60 microcosms (five replications per treatment), which were incubated in darkness at +20 degrees C and a constant relative air humidity …
Palladium-based catalytic systems for the synthesis of conjugated enynes by Sonogashira reactions and related alkynylations
2007
Conjugated alkynes are recurring building blocks in natural products, a wide range of industrial intermediates, pharmaceuticals and agrochemicals, and molecular materials for optics and electronics. The palladium-catalyzed cross-coupling between sp(2)-hybridized carbon atoms of aryl, heteroaryl, and vinyl halides with sp-hybridized carbon atoms of terminal acetylenes is one of the most important developments in the field of alkyne chemistry over the past 50 years. The seminal work of the 1970s has initiated an intense search for more general and reliable reaction conditions. The interest in the catalytic activation of demanding substrates, the need to minimize the consumption of depletive r…
Renewable Energy Technologies for Economic Development
2020
Indonesian villages are facing dangerous condition. Every year, young people are deserting the villages. To overcome this problem, Tangsi Jaya hamlet, West Java, has been provided with 18 kW micro-hydro to supply electricity both to the community and to Small Processing Center for ground coffee production. Results of cash flow analysis for ground coffee in Tangsi Jaya hamlet, with total investment of IDR 110 750 000 and discount rate of 18 % for 5 yr. Banyumeneng I hamlet, Yogyakarta with an investment cost IDR 95 000 000 and production cost of IDR 34 195 000 yr–1 and the interest rate of 14 % yr–1, the payback period was estimated to be 3 yr with ROI of 40 %. PEST analysics indicate that t…
Copenhagen failure : a rhetorical treatise of how speeches unite and divide mankind
2010
The purpose of this treatise is to analyse five of the Copenhagen Climate Convention's main speeches to see how they supported or weakened the agreement possibilities in the convention. Particular focus will be on the elements that divide or unite negotiators and whether the summit's failing outcome is already built in the pre-planned speeches held at the main podium. Theoretically, the study builds on Kenneth Burke's identification thesis and Elizabeth L. Malone's climate change debate analysis. I combine these in my analysis using a revised version of Malone's argument family classification tool putting it into Burke's theoretical framework. The central concept is Burke's identification, …
HOMEMADE SLOW-ACTION FERTILIZERS, AS AN ECONOMIC SOLUTION FOR ORGANIC FOOD PRODUCTION
2017
Organic plant cultivation, especially those intended for human consumption, poses new requirements for gardening. It is recommended to use organic slow-action fertilizers, which provide doses of nutrients essential for plants for a long time. Particularly valuable fertilizers are those that arise within the household, due to their high quality and the absence of costs associated with their purchase and transport. Organic matter contained in the food industry waste or arising in households, in the absence of contamination by other types of waste, can be used for self-production of organic fertilizer. The paper presents the results of testing organic fertilizers, which you can make yourself, …

Fashion Technology : What Are the Limits of Emerging Technological Design Thinking?
2021
Designing intelligent technologies is a multidisciplinary process. From this perspective, fashion has continued to be an under explored dimension of technology design. While there persistently are connections between the term fashion and the clothing design industry, an historical and sociological approach to fashion reveals a much deeper and permeating understanding of the notion and its implications across the technological world. During recent popular developments, the interrelationship between fashion as a concept and technology as components and proponents of fashion – technology as fashion promoter (think of Tiktok, Instagram, Facebook and even LinkedIn for example), and technology as…
Cognitive Impairment in Multiple Sclerosis Is Reflected by Increased Susceptibility to the Sound-Induced Flash Illusion
2019
Objective: To determine whether the performance of multiple sclerosis (MS) patients in the sound-induced flash illusion (SiFi), a multisensory perceptual illusion, would reflect their cognitive impairment.Methods: We performed the SiFi task as well as an extensive neuropsychological testing in 95 subjects [39 patients with relapse-remitting MS (RRMS), 16 subjects with progressive multiple sclerosis (PMS) and 40 healthy control subjects (HC)].Results: MS patients reported more frequently the multisensory SiFi than HC. In contrast, there were no group differences in the control conditions. Essentially, patients with progressive type of MS continued to perceive the illusion at stimulus onset a…
ALIGNEMENT UNI ET TRIDIMENSIONNEL DE MOLÉCULES PAR IMPULSION LASER FEMTOSECONDE
2007
This thesis is devoted to the study of the alignment of linear and asymmetric top molecules generated by an intense laser pulse. In the case of short pulses with respect to molecular rotation, periodic alignment appears in field-free conditions after the extinction of the field. We study theoretically and experimentally the effects of intensity, temperature and polarization of the electric field on produced alignment. If the field is linearly polarized, the interaction leads to the alignment of the most polarizable axis of the molecule. If the field is elliptically polarized, the pulse can generate a simultaneous alignment of the three principal axes of inertia of an asymmetric top molecule…
Automatisation des tableaux de bord et cohérence du contrôle de gestion : à propos de deux cas
2007
Cet article presente les resultats d’une enquete exploratoire dont l’objet est l’etude des rapports entre l’automatisation des tableaux de bord et la coherence du controle de gestion. A partir de deux cas juges exemplaires, celui d’une entreprise industrielle et celui d’une banque, nous etudions cette relation sous l’angle du partage des representations et de la coherence des comportements. Il en ressort que l’augmentation de la formalisation ne cree pas davantage de rigidite mais produit au contraire plus de dynamique ou de continuite et de permanence. Cependant, les resultats montrent aussi la limite d’une gestion automatique de la coherence dans la mesure ou les informations necessaires …
