Different Approaches to Oxygen Functionalization of Multi-Walled Carbon Nanotubes and Their Effect on Mechanical and Thermal Properties of Polyamide 12 Based Composites.

In this work the preparation of polyamide 12 (PA12) based composites reinforced with pristine and surface-modified carbon nanotubes is reported. A qualitative and quantitative evaluation of multi-walled carbon nanotube functionalization with oxygen containing reactive groups achieved by different procedures of chemical treatment is presented. Simple strong oxidative acid treatment as well as chlorination with subsequent chloroacetic acid treatment were applied.

[Variable magnetic fields in the treatment of tics disorders - preliminary results].

Introduction: Tics disorders is frequent pathological syndrome, particularly typical for children's age. The symptoms of this disease are differential, and their intensification individualized, which makes difficult unique recognition. Tics disorders concern the most often the muscles of face, head, upper limbs and trunk.

[Assessment of antagonistic activity in vitro Lactobacillus spp. strains againts Clostridum difficile strains isolated from gastrointestinal tract of patients hospitalized in three hospitals in region Mazovia].

Introduction: The aim of this study was to evaluate the antagonistic activity of Lactobacillus strains against clinical C. difficile strains isolated from faecal samples of adults patients with diarrhea. A total 61 strains of C.

Carbon-nanotube-based stimuli-responsive controlled-release system.

A stimuli-responsive controlled-release delivery system based on carbon nanotubes is demonstrated. Through TEM, FTIR spectroscopic, and thermogravimetric analysis, functional groups have been successfully attached to the open ends of the tubes, thereby enabling functionalized silica spheres to preferentially attach to the ends. This, in essence, plugs the ends of the tube.

[Rehabilitation of children after craniocerebral injuries with particular attention paid to the reflex stimulation Powiertowski's method. Preliminary study].

Introduction: An increasing number of craniocerebral injuries among children is becoming a serious therapeutic problem for emergency wards and for chronic treatment wards. The most important problem among these patients is a lengthening period of consciousness disorders. The aim of the study is to present a sample method of rehabilitation of children with brain injury.

Tibial nerve somato-sensory evoked potentials in idiopathic scoliosis.

Background. For many years the etiology of idiopathic scoliosis has been a topic of interest for researchers and clinicists. Material and methods.

Hoffmann reflex in idiopathic scoliosis.

This study was carried out in order to determine the dependence of selected Hoffmann reflex parameters on type, progression and morphology of idiopathic scoliosis (IS). Data collected from 129 girls with IS (59 progressive and 70 non-progressive cases) aged 7-16 years and 24 healthy subjects were analysed. H-reflex index (IH) and H/M amplitude index (IH/M) were calculated.

[Developmental age idiopathic osteoporosis--diagnostics and rehabilitation].

Developmental age idiopathic osteoporosis is a rare metabolic disease, which pathomechanism is different from involutional osteoporosis. Its etiology still remains unknown. An onset of the disease is rapid, affecting previously healthy children of both sexes aged 3.
