ISSN: 1365-3180Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: The research reported here had the objective of evaluating the effect of trifluralin (2,6-dinitro-N,N-dipropyl-4-trifluoromethylaniline), bifenox (methyl-5-(2,4-dichlorophenoxy)-2-nitrobenzoate) and vernolate (S-propylN,N-dipropyl-(thiocarbamate)) on soyabean (Glycine max (L.) Merr.) leaf wax production. The applications of vernolate at 3.36 and 5.4 kg ai ha−1 reduced the chloroform-soluble extraction of the soyabean leaves to 90% and 88%, respectively, under glasshouse conditions and to 83% and 81%, respectively, under field conditions, when compared to the untreated control taken as 100%. Trifluralin, bifenox and vernolate at 1.68 kg ai ha−1 did not reduce leaf wax production. Effet de traitements herbicides sur la fraction soluble dans le chloroforme des feuilles de soja (Glycine max. (L.) Merr.)Le présent travail a pour but d'évaluer l'effet de la trifluraline (2,6-dinitro-N,N-dipropyl-4-trifluor-omethylaniline), du bifénox (méthyl-5-(2,4-dichlorophenoxy)-2-nitrobenzoate) et du vernolate (S-propyl-N-N-dipropyl thiocarbamate) sur la production des cires foliaires chez le soja (Glycine max (L.) Merr.). L'application de vernolate à 3,36 et 5,04 kg m.a. ha−1 a réduit l'extrait chloroformique foliaire à 90 et 88%, respectivement, chez des plantes cultivées en serre, et à 83% et 81%, respectivement, chez des plantes cultivées au champ, par rapport aux 100% trouvées chez les téemoins non traités. La trifluraline, le bifénox et le vernolate à la dose de 1,68 kg/ha n'ont pas réduit la production de cires foliaires.Ueber die chloroformlösliche Fraktion von Sojabohnenblättern nach HerbizidapplikationenIn den hier publizierten Versuchen wurde der Einfluss von Trifluralin (2,6-dinitro-N,N-dipropyl-4-trifluoromethylaniline), Bifenox (Methyl-5-(2,4-dichlorphenoxy)-2-nitrobenzoate) und Vernolat (S-propyl N,N-thiocarbamate) auf die Ausbildung der Wachsschicht auf den Blättern von Soyabohnen (Glycine max (L.) Merr.) untersucht. Die Anwendung von 3,36 und 5,04 kg ai ha−1 Vernolat verminderte die durch Chloroform extrahierbaren Anteile von Soyablättern im Gewächshaus auf 90 resp. 88%, in Freilandversuchen auf 83 resp. 81%, im Vergleich zu den mit 100% eingesetzten Extrakten aus unbehandelten Pflanzen. Trifluralin, Bifenox und 1, 68 kg ai ha−1 Vernolat verursachten keine Verringerung der Wachsproduktion der Blätter.Type of Medium: Electronic ResourceURL: -

Published 1973Staff ViewISSN: 1752-1688Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Architecture, Civil Engineering, SurveyingGeographyNotes: : A river basin-wide water quality management system is considered. The river receives thermal as well as organic wastes. At-source treatment of these pollutants is imposed to control the basin-wide water quality. The related water quality standards are: the minimum DO concentration, the maximum allowable BOD concentration, the maximum allowable stream temperature, and the allowable rise in stream temperature. The general dynamic mathematical model representing water quality in streams and the thermal effects on BOD and DO concentrations is presented. The model is highly nonlinear in nature. The optimal management problem involving the model is solved by a recently developed nonlinear propgramming technique - the generalized reduced gradient (GRG) method. Comparison of results obtained by the GRG method vs. dynamic programming, and of results using a more realistic mathematical model vs. a simple model are presented. The analysis procedure can be applied to designing new and examining existing water quality programs, and to study the influence of alternate policies and constraints.Type of Medium: Electronic ResourceURL: -

Details are given on the laser, methods of delivering light into the bladder, suitable commercial dosimetry systems and instrumentation suitable for making light measurements on the bladder wall during therapy. New alternative photosensitizers are discussed in some detail. Some early clinical results are presented and the current problems with this type of therapy are highlighted.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-1998Source: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract Pneumatic reduction of ileocolic intussusception in children has been used in Argentina and in China for more than 25 years but has only recently been attempted in North America. It is reported to be safer and more effective than reduction by the hydrostatic pressure of a barium suspension. Our preliminary experience with four patients has been rewarding and we believe it may become the method of choice.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-041XKeywords: Key words Neuroblasts ; Cell clusters ; Fascicles ; Midbrain ; GrasshopperSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract We have studied the embryonic development of the pars intercerebralis/central complex in the brain of the grasshopper using immunocytochemical and histochemical techniques. Expression of the cell-surface antigen lachesin reveals that the neuroblasts of the pars intercerebralis first differentiate from the neuroectoderm at around 26% of embryogenesis. Differentiation of medial and lateral neuroblasts occurs first. By the 28% stage a more or less uniform sheet of 20 neuroblasts has formed. As a result of both cell proliferation and cell translocation, the pars intercerebralis proliferative cluster in each hemisphere expands so that at 30% the most medial neuroblasts lie apposed at the midline. We followed the further development of the pars intercerebralis of each brain hemisphere using bromo-deoxy-uridine incorporation and osmium-ethyl-gallate staining. Within the pars intercerebralis itself, the neuroblasts redistribute into discrete subsets. The neuroblasts of each subset generate clusters of progeny which extend in a stereotypic, subset-specific direction in the brain. We have used this feature to identify one subset of four neuroblasts as being the likely progenitor cells for four clusters of embryonic neurons (W, X, Y, Z) which develop at around 55% of embryogenesis. We show that these progeny project axons via four discrete fascicles (w, x, y, z) into the embryonic central complex. At the single cell level, Golgi impregnation reveals that the axons from these neighbouring cell clusters remain discrete, and those from the same cluster tightly fasciculated, as they project into the central complex, consistent with a modular organization for this brain region.Type of Medium: Electronic ResourceURL: -

During postnatal development, a decrease in the ratio of the 2 classes of protein kinases was seen in prostates, whereas increases of the ratios of the enzymes were found in epididymides and testes.Type of Medium: Electronic ResourceURL: -

The dose-dependence of the inhibition of A-PK or the stimulation of G-PK was observed as a function of the amount of protein kinase modulators in the cerebellum of mice receiving different doses of ethanol.Type of Medium: Electronic ResourceURL: -
