food safety is a global concern due to an increasing awareness of consumers concerning exposure of foods to chemicals and contamination with such hazardous biochemicals as dioxins, mycotoxins, pesticides, polycyclic aromatic hydrocarbons, drugs and hormones. patulin is one of the most injurious mycotoxins produced by a variety of molds, particularly aspergillus and penicillium species. based on...

conclusions overall, incidence of birth trauma in kashan city was lower in comparison with most studies. considering existing risk factors, further monitoring on labor, and delivery management in teaching hospitals are recommended to prevent birth injuries. in addition, careful supervision on students and residents' training should be applied in teaching hospitals. patients and methods in this ...

The necessity of conserving both scattered energy and asymmetry factor for ballistic incidence after either FVM or DOM discretization is convincingly shown by analyzing ultrafast laser radiative transfer in a cubic enclosure housing a participating medium. A phase-function normalization technique introduced previously by the present authors to correct for non-conservation of energy and asymmetr...

abstract intensive and inefficient use of energy leads to degradation of natural resources and environmental problems. this study evaluated the relationship between the energy of consumed inputs and yield of tomato, cucumber and melon using the cobb–douglas production function. the data were collected from 90 farmers in firoozabad using a questionnaire. the farmers were chosen by simple random ...

The adsorption of molecular hydrogen on sulfurand chlorine-covered Pd(100) in a (2×2) geometry is studied by ab initio molecular dynamics simulations. The potential energy surfaces of H2/S(2 × 2)/Pd(100) and H2/Cl(2× 2)/Pd(100) are rather similar. Consequently, also the dependence of the sticking probability on incident kinetic energy, angle of incidence and internal excitations are very close....

Incidence rates of kidney cancer are thought to be highest in places situated at high latitudes and in populations with high intake of energy from animal sources. This suggests that low 25-hydroxyvitamin D status, due to lower levels of UVB irradiance, and energy from animal sources might be involved in etiology. The association of latitude with age-adjusted incidence rates was determined for a...

Background: Given that abdominal obesity increases the risk of affecting metabolic and cardiovascular diseases, this study was conducted to determine the relationship between energy and macronutrient intake with women's abdominal obesity in Sabzevar. Methods: In this study, 225 female nurses and medical staff in Vase’e hospital of Sabzevar were selected. In order to assess the dietary int...

We examine a dual-quaternion formulation for expressing the relative rigid body motion between two objects when incidence constraints are to be observed. The incidences are between points, lines and planes, of the two parts. Both parametric and implicit representations are investigated. Several examples illustrate the techniques .

The energy of a matrix is the sum of its singular values. We study the energy of (0, 1)matrices and present two methods for constructing balanced incomplete block designs whose incidence matrices have the maximum possible energy amongst the family of all (0, 1)-matrices of given order and total number of ones. We also find a new upper bound for the energy of (p, q)-bipartite graphs. AMS Subject...

The prevalence of obesity in children has continued to increase despite a general increased awareness of health and fitness. Epidemiologic data show that the prevalence of obesity in children is approximately 25%, with a higher prevalence in some subgroups of the population. In addition, the incidence of obesity-related diseases is dramatically increasing in children. For example, the incidence...
