In a second step, since the lifetimes of the solutions are uncertain and difficult to predict given that future political, cultural and energy price evolutions are unknown, the hypotheses used in the first step are called into question and greenhouse gas emissions are evaluated according to variable lifetimes.
Instruments of great generality that make few ambiguous assumptions about the nature of extraterrestrial life require luck (e.g., an animal or protist must walk or swim by during the operating lifetime of the camera) or the solution of difficult instrumental problems (e.g., the acquisition and preparation of samples for remote electron microscopic examination).
From Fig. 2d, we can see that the lifetime of QD solution reduced from 19.5 to 14.1 ns for ITO/PEDOT PSS/poly-TPD/QDs fITO/PEDOT PSS/poly-TPD/QDs
That said that "Procurement decisions will be made on the basis on the best value for money solution to the business requirement, taking account of total lifetime cost of ownership of the solution, including exit and transition costs, after ensuring that solutions fulfil minimum and essential capability, security, scalability, transferability, support and manageability requirements".
The poor stability and short lifetime of the anion complex in aqueous solution further complicates its direct detection.
A series of novel heterocycle-containing spirooxazines have been designed and synthesized, and their photochromic properties were investigated under flash photolysis and continuous irradiation in particular regard to the fatigue resistance, the lifetime of the colored merocyanine form in various solutions and polymers.
The radiative lifetime, determined as an average value of the ratio of fluorescence quantum yield and fluorescence lifetime of
Determination of the fluorescence quantum yield and the lifetime of the excited state for ThT in solutions of different viscosity and temperature allowed the determination of the radiative lifetime (τr = 7.8 ns) and the calculation of excited state lifetime for ThT in water at room temperature (τ≈0.001 ns).
Fully differentiated lens fiber cells do not produce or degrade proteins, so existing proteins must remain stable in solution for the lifetime of the individual.
The response time was found to be 20s for concentration of ≥1 × 10-3 M and ≥ 30 s for concentration 1 × 10-4 M. Day-to-day reproducibility of the sensor is about × 0.5 MV for the same solution and the useful lifetime of the sensor is 4 weeks, during which the potential slope is reproducible to within ±1 MV/ decade.
