Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Traveling wave is a wave in which the positions of maximum and minimum amplitude travel through the medium. An oceanic wave is a disturbance, which is created by a wind flow, shipping and similar object subsequently travels through it from one location to another and transfer energy. Some times rogue type waves are created that may be harmful in clam situation even for harbor and coastal region. Thus modeling of oceanic phenomena in PDEs and their traveling and solitary wave solutions are important fact. The mechanism by which a oceanic solitary wave propagates itself through an ocean involves multi-interaction; traveling through a medium and a crest is moving along from wave to wave. In fact, one would observe a distinct wave pattern (in the form of a sine wave) traveling through the medium. This sine wave pattern continues to move in uninterrupted fashion until it encounters another wave along the medium. 68 pp. Englisch.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The research was conducted to determine six trace metals concentration, Arsenic (As), Cadmium (Cd), Chromium (Cr), Copper (Cu), Lead (Pb) and Zinc (Zn) in insects (Periplaneta Americana, Chrysomya megacephala), fish (Lates calcarifer), malacostracan (Penaeus monodon), water and sediments collected from coastal area of Sitakunda upazila. The analysis of metals showed that the range of As was (<80-8720), Cd was (10-420), Cr was (962-66008), Cu was (34.1-65754), Pb was (141-18000) and Zn was (1088-211766). Except As, all the metals concentration was higher in all samples. The accumulation power of Zn was higher in all samples especially it was highest in the insect samples. Most of the values of As were below the detection limit. The levels of trace metals also compared with the standards of WHO and FAO. Except As and Cd, all the values were higher than the permissible limit. Pearson correlation matrix revealed that these metals inter-element relationship was positive and might have originated from the same sources. Pb and Cr, Pb and Cu, Pb and As, Cr and Cu, Cr and As, Cu and As showed positive and highly significant correlation.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - La recherche a été menée pour déterminer la concentration de six métaux traces, l'arsenic (As), le cadmium (Cd), le chrome (Cr), le cuivre (Cu), le plomb (Pb) et le zinc (Zn) dans les insectes (Periplaneta Americana, Chrysomya megacephala), les poissons (Lates calcarifer), le malacostracan (Penaeus monodon), l'eau et les sédiments recueillis dans la zone côtière de Sitakunda upazila. L'analyse des métaux a montré que la gamme de As était (<80-8720), Cd était (10-420), Cr était (962-66008), Cu était (34.1-65754), Pb était (141-18000) et Zn était (1088-211766). A l'exception de l'As, la concentration de tous les métaux était plus élevée dans tous les échantillons. Le pouvoir d'accumulation du Zn était plus élevé dans tous les échantillons, en particulier dans les échantillons d'insectes. La plupart des valeurs de As étaient inférieures à la limite de détection. Les niveaux de métaux traces ont également été comparés aux normes de l'OMS et de la FAO. A l'exception de l'As et du Cd, toutes les valeurs étaient supérieures à la limite permise. La matrice de corrélation de Pearson a révélé que la relation inter-éléments de ces métaux était positive et pouvait provenir des mêmes sources. Pb et Cr, Pb et Cu, Pb et As, Cr et Cu, Cr et As, Cu et As ont montré une corrélation positive et hautement significative.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Die Untersuchung wurde durchgeführt, um die Konzentration von sechs Spurenmetallen zu bestimmen: Arsen (As), Kadmium (Cd), Chrom (Cr), Kupfer (Cu), Blei (Pb) und Zink (Zn) in Insekten (Periplaneta Americana, Chrysomya megacephala), Fischen (Lates calcarifer), Malacostracan (Penaeus monodon), Wasser und Sedimenten aus dem Küstengebiet von Sitakunda upazila. Die Analyse der Metalle zeigte, dass der Bereich von As (<80-8720), Cd (10-420), Cr (962-66008), Cu (34,1-65754), Pb (141-18000) und Zn (1088-211766) betrug. Mit Ausnahme von As war die Konzentration aller Metalle in allen Proben höher. Die Akkumulationskraft von Zn war in allen Proben höher, besonders hoch war sie in den Insektenproben. Die meisten Werte von As lagen unter der Nachweisgrenze. Die Werte der Spurenmetalle wurden auch mit den Normen der WHO und FAO verglichen. Mit Ausnahme von As und Cd lagen alle Werte über dem zulässigen Grenzwert. Die Pearson-Korrelationsmatrix zeigte, dass die Beziehung zwischen diesen Metallen und den Elementen positiv war und möglicherweise aus denselben Quellen stammte. Pb und Cr, Pb und Cu, Pb und As, Cr und Cu, Cr und As, Cu und As zeigten eine positive und hoch signifikante Korrelation.…
