A very active subfield in high energy physics recently is the study of hadrons with heavy-light quark content [1]. A major effort has been spent in calculating the Isgur-Wise function, which, once it is determined, can be widely used in calculations of heavy meson decay (b → c) processes. After an initial exploration [2], calculations of the Isgur-Wise function on the lattice [3– 5] have quickl...

The article discusses the need for automation in agriculture and specifically process of preparing feed by grinding corn grain using hammer mills. aim work is to develop a Python program calculate productivity an experimental mill. also describes experiment method determining degree investigates factors affecting crushing process. ultimate goal increase labor productivity, improve product quali...

background : family caregivers are an essential part of health care services for elderly with dementia disorders, because of providing care for such patients is a big burden for their families. this study aimed to assess the effects of family education program in reducing the burden of families of elderly with dementia. methods : this was a clinical trial, in which 50 family caregivers of the e...

In a Z-core sandwich panel, the shear stiffness of the sandwich panel in the weak direction which is perpendicular to the placement of the Z-cores is much smaller than the bending stiffness because the hollow section between the two facing plates cannot sustain shear action. Because of this fact, the shear deformation of a Z-core sandwich panel under bending in the weak direction cannot be igno...

background: studies showed that poor quality of sleep is a common problem among the elderly. because of drug complications and side effects such as drug dependency and resistance and decrease of sleep depth in long‑term intake of sleep medication, cognitive‑behavior therapy including sleep restriction therapy which does not cause these problems is more considered. materials and methods: this is...

[1] We appreciate the commentary by Neuman [2006] and the opportunity for discussion and further clarification of our article [Ritzi et al., 2004]. In his commentary, Neuman expounds upon his derivation of a model for the permeability semivariogram [Neuman, 2003, equation (53)] and describes aquifer architecture that would be represented by such a model. As requested by the Associate Editor, ou...

Heavy metal pollution is a major environmental problem facing humankind. Locating the source and distribution of heavy pollutants around mines can provide scientific basis for control. The structure effect random semivariogram be used to determine reason spatial differences in content surface soil, coefficient variation regression analysis confirm that verification accuracy meets geostatistical...
