Certain materials "decay" at the atomic level over a period of time, giving off "radiation" in the form of energy or subatomic particles. This radiation can be harnessed and used for a variety of industrial applications. Some of the commonest of these which are used in New Zealand are listed below, although many others exist that are either only used to a small extent or used exclusively overseas.
At the PANIC conference in Osaka in October 2002, a collaboration working at SPring-8 announced a baryon state, the Θ(1540) with a decay mode Θ → nK. Assuming the decay is not Weak, that meant it had strangeness +1, and therefore was an exotic state (“exotic” in the sense that it is a baryon that cannot be a q state). It can be a ududs̄ state: a pentaquark. It has since been found at other labs ...
Using data collected with the CLEO detector operating at the CESR e+e− collider at √ s = 3.974.26GeV, we investigate 15 charmonium decay modes of the ψ(4040), ψ(4160), and Y (4260) resonances. We confirm, at 11σ significance, the BaBar Y (4260)→ π+π−J/ψ discovery, make the first observation of Y (4260) → π0π0J/ψ (5.1σ), and find the first evidence for Y (4260) → K+K−J/ψ (3.7σ). We measure e+e− ...
This article describes in detail the influence of sowing dates on growth, development and productivity various varieties winter wheat. Wheat occupies a special place among grain crops terms nutritional value yield. It is known that Uzbekistan, wheat saturated with vital factor - light. On average, 2,500-3,000 hours sunshine per year fall soil our country. Therefore, agriculture, it possible to ...
Grazing is the cheapest way to feed cattle on a cost per pound of nutrient basis. However, producers with limited land resources in Kentucky have been able to use commodities or grain by-products to increase cattle numbers due to low cost and availability of these inputs. Extending the grazing season is one solution that would enable producers to reduce costs and expand production with little o...
The stirring of a small, passive heterogeneity in an unsteady circulation is investigated by following the boundary of the heterogeneity; the circulation mimics features of plate-scale flow. After initial release, the heterogeneity is stirred and subsequently consists of at least one large "blob" connected to long, but thin tendrils. Tendrils exponentially lengthen and exponentially thin with t...
We consider simultaneous optical data obtained during the recent X-ray turn-off of CAL 83. Combining the optical behaviour with the observed X-ray decay time, we show that a model of cessation of steady nuclear burning is viable if the white dwarf is massive. Our model provides a natural explanation for the subsequent return of the supersoft X-ray emission.
parameterized by μ > 0, and prove a representation theorem for its solutions using the theory of special functions. This representation is used to obtain Lp–Lq estimates for the solution and for the energy operator corresponding to this Cauchy problem. Especially for the L2 energy estimate we determine the part of the phase space which is responsible for the decay rate. It will be shown that th...
Policies are used to control the behavior of large-scale systems. After policies are designed and before policies are implemented, it should be possible to analyze the policies and verify that they behave as expected. Graph transformations provide a good method to carry out the analysis and verification because of the intuitive representation of policies and the mature theory. Here, we show how...
