ISSN: 1433-3058Keywords: Feedforward neural networks ; Filtering ; Thermal analysis ; Differential scanning calorimetry ; Kinetics ; SimulationsSource: Springer Online Journal Archives 1860-2000Topics: Computer ScienceMathematicsNotes: Abstract Feedforward neural networks have been used for kinetic parameters determination and signal filtering in differential scanning calorimetry. The proper learning function was chosen and the network topology was optimised using an empiric procedure. The learning process was achieved using various simulated thermoanalytical curves computed for several thermodynamic and kinetic parameters. Various amounts of simulated noise were added on the power signals. The resilient-propagation algorithm led to the best minimisation of the error computed over all the patterns. Relative errors on the thermodynamic and kinetic parameters were evaluated and compared to those obtained with the usual thermal analysis methods. The results obtained are very promising, and the errors are much lower than with usual methods, especially in the presence of noisy signals. This study shows that simulated thermoanalytical curves produced by Joule effect may be used for the deconvolution of the response of the apparatus, by using artificial neural networks.Type of Medium: Electronic ResourceURL: -

The resilient-propagation algorithm have led to the best minimization of the error computed over all the patterns. Relative errors on the thermodynamic and kinetic parameters were evaluated and compared to those obtained with the usual thermal analysis methods (single scan methods). The errors are much lower, especially in presence of noisy signals. Then, our program was adapted to simulate thermal effects with known thermodynamic and kinetic parameters, generated electrically, using a PC computer and an electronic interface on the serial port. These thermal effects have been generated by using an inconel thread.Type of Medium: Electronic ResourceURL: -

ISSN: 1572-8943Keywords: binary coding parameters ; calculation of flame temperature ; computer program ; crossover ; data processing ; dissociative reactions ; genetic algorithms ; genetic operators ; pyrotechnic reactionsSource: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract A program is described which enables performing of genetic algorithms for the determination of two positive real parameters. These new types of procedures are tested on a software of determination of flame temperatures previously developed in a fully classic way. The genetic operators used are crossover and mutation. They perform operations on a binary coded form of the parameters. The goal of the present study consists in developing and optimizing a genetic determination of the parameters at a given temperature. We succeed in selecting the general architecture of the procedure and implementing it in our main software of calculation of flame temperature. We have chosen this pyrotechnic field of application because we knew the behaviour of the real parameters, so the debugging operations were easier.Type of Medium: Electronic ResourceURL: -

ISSN: 1572-8943Keywords: DSC ; PID controllers ; tuning PID parametersSource: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract Some DSC calorimeters, such as the model DSC 111, built by the society Setaram, allow the user to set the temperature programming parameters. Usually default values furnished by the constructor are often used, but it is very interesting to study the thermal behaviour of the regulation of the calorimeter under different conditions and with different kinds of set point temperatures. For this research, we have developed in C language a set of software in order to demonstrate the behaviour of the (proportional integral derivative) PID controller of the DSC. It can help the user to choose correct values for P, I and D parameters according to the kind of experiment conducted. The software allows studies of extra parameters, such as the sampling rate of the computerized PID controller or the determination of filtering of the correction.Type of Medium: Electronic ResourceURL: -

ISSN: 1572-8943Keywords: kineticsSource: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyDescription / Table of Contents: Zusammenfassung Cu(II)-komplexe von Acenaphthoquinonmono-(4-methyl-quinolinyl)-hydrazon (AMH) der allgemeinen Zusammensetzung [CuLX2] (mitL=AMH;X=Cl, Br, I, OAc oder NO3) -ausgenommen die Sulfato-komplexe, die über die allgemeine Zusammensetzung [CuLSO4]2 verfügen — wurden hergestellt und mittels Elementaranalyse, Messungen des magnetischen Momentes, Leitfähigkeitsmessungen, IR, elektronen- und EPR-spektroskopischen Techniken und durch Thermoanalyse untersucht. Für alle Komplexe wurde eine planare Geometrie gefunden. Die TG-Kurven zeigen, daß die Komplexe in einem Schritt zersetzt werden, wobei am Ende dieses Schrittes CU2O gebildet wird.Notes: Abstract A software is described enabling kinetic analysis under non-isothermal or isothermal conditions from DSC, or from TG data. The program offers thirteen methods of kinetic analysis for DSC, three for isothermal analysis and two for TG, with eight different functions for the choice of the proper mechanism for each of them.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-5028Keywords: microsatellites ; CA repeats ; sunflower ; plant genomeSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract The importance of genetic polymorphism detected by ‘microsatellites’ is now well established in mammalian genomes. Sequences with a CA repeat, specific to sunflower, Helianthus annuus L., were found by screening a genomic library in M13. After amplification, some polymorphism was detected on these sequences within a sample of cultivars and populations.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-2242Keywords: Enzymatic systems ; Heterosis ; Markers ; SunflowerSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract Nine polymorphic isoenzymatic systems were studied in 39 cultivated sunflower populations originating from ten countries. Analysis of combining abilities with four tester lines was also performed on these populations for seed yield, seed moisture and seed oil content. The MDH, PGI, PGD and GOT systems appeared to provide the best discrimination of specific combining ability effects with the four testers. The MDH and GOT systems provided a between-population structure that was consistent with the country of origin.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-2242Keywords: Key wordsfad3 gene ; Δ15 Microsomal desaturase ; Linolenic acid ; Mutant ; Rapeseed ; Specific gene mappingSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract In rapeseed, which is an agronomically important oilseed, variation in the linolenic acid content of the oil has been obtained through chemical mutagenesis treatment. Conventional breeding of this quantitative trait, however requires specific molecular markers. By means of biochemical experiments, we have established that the induced variation in linolenic acid content is associated with the fad3 gene encoding the microsomal Δ15 desaturase. Using a pair of primers specific to this gene and a doubled haploid progeny derived from a low linolenic×high linolenic acid F1hybrid, we have identified a polymorphism of the fad3 alleles between the low- and the high-linolenic acid genotypes. The structure exon/intron of the fad3 DNA sequence seems to be very similar to that of the Arabidopsis fad3 gene. The choice of the primer pair allows specific amplification of one of the two rapeseed fad3 genes. The value and contribution of specific markers to conventional plant breeding is discussed.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-2242Keywords: Genetic relationship ; Population structure ; Picea abies ; Isozymes ; PerennialSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Summary Natural populations are currently the basic material for studying forest tree breeding, but little is known on the genotypic spatial structures in these stands. The use of gene markers, such as isozymes, leads to the determination of part of the allelic constitution of individuals. A method is presented here to estimate the degree of genetic relationship between any pair of genotypes. A French Picea abies population is analyzed by these means and a slight but significant correlation between estimated genetic relationship and topographic distance is found.Type of Medium: Electronic ResourceURL:
