in the course of this study, empirical models were developed for the pressure-density relationship in a large cubic baler for baling alfalfa and barley straw. least squares regression analysis was employed to develop the empirical model and estimate the model coefficients by minimizing the summation of the squared differences between data resulting from the developed empirical model and the cor...

primary hepatic lymphoma is a rare malignancy usually presenting with symptoms of fever, hepatomegaly, jaundice and weight loss. this picture mimics infectious and inflammatory disorders and thus delays the diagnosis. here, we present a 47-year old man with prolonged fever who underwent several investigations and, in the meantime, developed fulminant hepatic failure before the diagnosis could b...

contact mechanics is related to the deformation study of solids that meet each other at one or more points. the physical and mathematical formulation of the problem is established upon the mechanics of materials and continuum mechanics and focuses on computations involving bodies with different characteristics in static or dynamic contact. contact mechanics gives essential information for the s...

pierre-gerlier forest and his colleagues make a strong argument for the need to expand policy capacity among healthcare actors. in this commentary, i develop an additional argument in support of forest et al view. forest et al rightly point to the need to have embedded policy experts to successfully translate healthcare reform policy into healthcare change. translation of externally generated i...

risk response planning is one of the main phases in the project risk management and has major impacts on the success of a large-scale project. since projects are unique, and risks are dynamic through the life of the projects, it is necessary to formulate responses of the important risks. the conventional approaches tend to be less effective in dealing with the impreciseness of risk response pl...

in this paper a laboratory study has been carried out on the effect of changing the type of soil filling cylindrical reinforcing elements from sm to gm on behavior of sandy soil. in this study the primary tests for evaluation of the impact of reinforced sand and gravel columns with diameters of 5 cm and heights of 15 cm subjected to vertical stresses of 50, 100, and 150 kpa were carried out in ...

we consider an approximation scheme using haar wavelets for solving a class of infinite horizon optimal control problems (ocp's) of nonlinear interconnected large-scale dynamic systems. a computational method based on haar wavelets in the time-domain is proposed for solving the optimal control problem. haar wavelets integral operational matrix and direct collocation method are utilized to ...

the authors describe a case of histiocyte-rich b-cell lymphoma (hr-bcl), a variant of diffuse large b-cell lymphoma, in a 51-year-old man. the patient presented with large axillary lymphadenopathy. histopathologic and immunohistochemical examination of lymph node biopsy revealed diffuse effacement of the lymph node architecture by reactive histiocytes and neoplastic cd20 positive b cells. react...
