objective: in patients with diabetes mellitus, increased rate of lipoprotein oxidation and oxidative stress have important role in diabetic angiopathy, including nephropathy. we designed a study for comparing the level of ox-ldl in diabetic patients with macro-albuminuria, micro-albuminuria, versus normo-albuminuric. materials and methods: one hundred and thirty five patients with type 2 diabet...

In this paper the kinematic and Jacobian analysis of a macro–micro parallel manipulator is studied in detail. The manipulator architecture is a simplified planar version adopted from the structure of the Large Adaptive Reflector (LAR), the Canadian design of the next generation of giant radio telescopes. This structure is composed of two parallel and redundantly actuated manipulators at the mac...

In this paper the dynamic analysis of a macro–micro parallel manipulator is studied in detail. The manipulator architecture is a simplified planar version adopted from the structure of the Large Adaptive Reflector (LAR), the Canadian design of next-generation giant radio telescopes. In this structure it is proposed to use two parallel redundant manipulators at the macro and micro level, both ac...

The work reported here combines elements of electromechanics, power electronics and applied control primarily in the analysis, design and control of energy conversion systems. The principal applications focus on systems involving: macro-scale rotating machinery; micro-scale (MEMS) sensors, actuators and energy converters; and flexible structures. In these applications, the dual use of electrome...

The requirements engineering (RE) process is a decision-rich complex problem solving activity. This paper examines the elements of organization-oriented macro decisions as well as process-oriented micro decisions in the RE process and illustrates how to integrate classical decision-making models with RE process models. This integration helps in formulating a common vocabulary and model to impro...

The effects of pH and chloride concentration on the electrochemical corrosion of copper in aqueous sodium chloride (NaCl) media were studied at the micro scale using a microcapillary droplet cell and at the macro scale using a conventional large scale cell. Using an experimental design strategy, electrochemical response surface models of copper versus pH and NaCl concentration were constructed ...

culture has always been regarded as the most important element of human communities; we can easily observe cultural changes. what causes these changes has been a matter of controversy. the issues such as people’s increasingly getting detached from each other, psychopathy, behavioral abnormalities, traditions being increasingly faded away, malformation, extravagancy and value conversion into ant...
