Significant advances have taken place in the last few years in the development of control designs for nonlinear infinite-dimensional systems. Such systems typically take the form of nonlinear ODEs (ordinary differential equations) with delays and nonlinear PDEs (partial differential equations). In this article we review several representative but general results on nonlinear control in the infi...

The analysis of a two-phase slug flow is of immense importance due to its vast applications in many industrial problems. A number of experimental and analytical studies have been carried out to study this complex and unwanted phenomena. Mostly these studies were limited to the liquid phase and to the statistical parameters and formation mechanism. So far no attempt has been made to study the ph...

over half of all reported traumatic brain injuries are the result of a motor vehicle accident. other then the direct head impact itself, the sheer forces of the accident can cause the brain also to collide against the internal bone of the skull. in fact, when a moving head comes to a quick stop, the brain continues in its movement, striking the interior of the skull. this can cause bruising of ...

introduction bacillus calmette-guérin (bcg) vaccine, a live attenuated mycobacterium bovis strain, is administrated to all newborn infants in endemic regions according to the current world health organization (who) recommendation. case presentation we report a 10-month-boy who was a known case of severe combined immunodeficiency (scid) admitted with multi-focal fusiform painful swelling in his ...

Laboratory studies have demonstrated that circadian clocks align physiology and behavior to 24-h environmental cycles. Examination of athletic performance has been used to discern the functions of these clocks in humans outside of controlled settings. Here, we examined the effects of jet lag, that is, travel that shifts the alignment of 24-h environmental cycles relative to the endogenous circa...

Some experimental observations on the fluidization characteristics of nanoparticles in the form of agglomerates with magnetic assistance are presented. The nanoagglomerates consist of Degussa Aerosil R974 fumed silica, with a primary particle size of 12 nm. An oscillating AC magnetic field is used to excite large (mm size) permanent magnetic particles mixed in with the nanoparticle agglomerates...

background: work is the key component for most people in regard to financial, social and wellbeing matters. employment is an important factor underpinning mental health disorders. however, unemployment remains an unsolved issue worldwide. numerous studies have focused on employment outcomes in people with severe mental illness (smi) but, only a few have explored their perspective on employment....

background: reading is known as one of the most important learning tools. research results consistently have shown that even a mild hearing impairment could affect the reading skills. due to the reported differences in reading comprehension skills between hearing impaired students and their normal hearing peers, this research was conducted to compare the differences between the two groups. the ...

severe congenital neutropenia is one of primary immunodeficiency disorders that characterized by severe neutropenia and is associated with severe systemic bacterial infections from  early  infancy.  granulocyte  colony  stimulating  factor  (gcsf)  is  clinically  used  as  a treatment for congenital and acquired neutropenia. the aim of this study was evaluation of gcsf (pd- grastim) in treatme...
