In a series of publications the Cummings-Stell model (CSM), for a binary mixture of associative fluids with steric effects, has been solved analytically using the Percus-Yevick approximation (PYA). The solution consists in a square well potential of width w, whose center is placed into the hard sphere shell (r < σ): at L = σ/n (n = 1, . . . , 4). This paper presents a general solution, for any ...

Certain kinds of two-phase random media, such as suspensions, porous media, and composite materials, are characterized by a discrete particle phase that is distributed throughout a continuous matrix phase (fluid, solid, or void). A fundamental understanding of the effective bulk properties of such systems rest upon knowledge of certain statistical quantities that describe how the phases are spa...

Di Family Glass and Stell (FGAS) untuk pemesanan masih menggunakan sistem manual yaitu dengan buku dan kertas, tentu ini akan memakan waktu juga sering terjadi kesalahan pada pencatatan pesanan kurang efisien jika dalam keadaan ramai. Juga kehabisan stok karena lupa terhadap persediaan yang ada sehingga terpaksa menolak pelanggan. Maka di perlukanya kasir barang lebih baik agar meningkatkan kin...

the ammi and sreg gge   are among the models that effectively capture the additive and multiplicative components of genotype × environment interaction (gei) and provide meaningful interpretation of multi-environment trials’ data set in the breeding programs. the objective of this study was to assess the effect of gei on grain yield of barely advanced lines and exploit the positive gei effect us...

It has been shown by Stell [J. Stat. Phys., 63, 1203 (1991)] that at low temperature monodisperse sticky spheres collapse to form coexisting close-packed solid and infinitely dilute gases. We show that polydisperse sticky spheres also collapse and calculate the collapse temperature. The polydisperse spheres separate into fractions with narrower polydispersities which can then solidify. This is ...
