Freshwater lakes are sensitive ecosystem and respond to the episodic changes from its surrounding environment. The physico-chemical factors of water and biological processes determine the quality of water which in turn indicates the diversity of fauna and flora that the water would support. However, the ecological factors of lake correlating with parasitic isopods under natural conditions are p...

Aim : To study the acute toxicity of λ-cyhalothrin in freshwater fish Labeo rohita by determining the 96 hours lethal concentration 50 (96 hrs LC ) and behavioural patterns of exposed fish. 50 Materials and Methods: A total 270 fingerling size fish were used to determine the 96 hours lethal concentration 50 (96 hrs LC ) of λ-cyhalothrin as per the guideline of Organization for Economic Co-opera...

Angesichts steigender Komplexität moderner Automatisierungssysteme gewinnen Netzwerkregelungssysteme wegen ihrer Modularität und vereinfachten Diagnose mehr und mehr an Bedeutung. In derartigen Systemen sind Prozess und Regler räumlich getrennt und über ein Kommunikationsnetz verbunden. Die dadurch induzierte Kommunikationstotzeit wirkt potenziell destabilisierend. In diesem Artikel wird eine n...

Assuming positive observation of neutrinoless double bata decay together with the CHOOZ reactor bound, we derive constraints imposed on neutrino mixing parameters, the solar mixing angle θ12 and the observable mass parameter 〈m〉β in single beta decay experiments. We show that 0.05 eV ≤ 〈m〉β ≤ 2 eV at the best fit parameters of the LMA MSW solar neutrino solution by requiring the range of the pa...
