The acoustic emission of fracture precursors is measured in heterogeneous materials. The statistical behaviour of these precursors is studied as a function of the load features and the geometry. We find that the time interval δt between events (precursors) and events energies ε are power law distributed and that the exponents of these power laws depend on the load history and on the material. I...

background: breaking bad news to cancer patients is one of the important responsibilities in the oncology setting. the purpose of this study is develop and validate a new theoretically based tool for measurement of attitude and practice of physicians toward breaking bad news. methods: the psychometric properties of the scale were established by following the guidelines of clark and watson. in t...

In the model fibers break due to two mechanisms: ...

in this study, we investigated the effect of savory (satureja hortensis) essential oil, garlic(allium sativum) powder, and garlic aqueous extract on fungal load of poultry feed. tothis end, savory essential oil and garlic aqueous extract each amounting 62.5, 125, and250 μl/ml and mg/ml, respectively, per kilogram of feed and garlic powder amounting2.5, 5, and 10 g/kg of feed were used. one and ...

Introduction: Dietary acid load contributes to metabolic acidosis, closely linked to cancer development through inflammation and cell transformation. There is very limited epidemiologic evidence; linking diet-dependent acid load and cancer risk. Since there are few published studies specifically on urinary pH and bladder cancer (BC) risk, we sought to explore this association in the present stud...

The effects of chronic dietary acid loads on shifts in bone mineral reserves and physiological concentrations of cations and anions in extracellular fluids were assessed in growing swine. Four trials were conducted with a total of 38 (8.16 +/- 0.30 kg, mean +/- SEM) Large White x Landrace x Duroc pigs randomly assigned to one of three dietary treatments. Semipurified diets, fed for 13 to 17 d, ...

stand establishment in crusting soil is one of the main concerns in the production of crops with delicate seedlings such as cotton, onions and rape seed. crust breaking, maintaining soil moisture and adding chemical and organic amendments to soil are different methods to weaken soil strength and allow the shoots to emerge. these methods are not always successful because they depend on factors s...

Thermobonding is widely used in producing of nonwovens. In this study various layers of thermobonded nonwovens were produced by altering the pressure, binder fibres and quality of blending. Mechanical properties of the so-called layers such as breaking strength and breaking elongation, bending rigidity and air permeability were assessed consequently. The structure of the layers was then studied...
