The variance-covariance method is employed at low doses and in radiation fields of low dose rates from an 241Am (4 nGy/s) and a 90Sr (300 nGy/s) source. The preliminary applications and results illustrate some of the potential of the method, and show that the dose average of lineal energy or energy imparted can be determined over a wide range of doses and dose rates. The dose averages obtained ...

In this paper, we characterise the compromise value of a game as the barycentre of the edges of its core cover. For this, we introduce the τ∗ value, which extends the adjusted proportional rule for bankruptcy situations and coincides with the compromise value on a large class of games.

We construct Darboux transformations for the supersymmetric KP hierarchy. We show that the naive candidate does not work due to the pressure of the odd flows,but its composition does give rise to a meaningful Darboux transformation. We also consider the b inary Darboux transformation for the hierarchy. The iterations of both type of Darboux transformations are briefly discussed.

The Calogero equation is used to illustrate the following two aspects of the Painlevé analysis of PDEs: (i) the singular expansions of solutions around characteristic hypersurfaces are neither single-valued functions of independent variables nor single-valued functionals of data; (ii) the truncated singular expansions not necessarily lead to the simplest, elementary, Bäcklund autotransformation...

Penurunan produksi biji kopi arabika diakibatkan oleh keberadaan hama penggerek yang melubangi sehingga mudah terinfeksi spora A. flavus. Tujuan dari penelitian ini untuk menguji efektivitas filtrat T. asperellum TKD terhadap flavus pada secara in vitro dan vivo. Perlakuan vivo yaitu kontrol negatif, positif, konsentrasi 10, 30, 50, 70, 90% (v/v). Parameter diamati adalah populasi setelah perla...

We investigate a number of algorithms that calculate the quark propagators for the overlap-Dirac fermion operator. The QCD simulations were performed at β = 5.9 with a lattice volume of 16 3 32.
