We demonstrate a method for inducing strain in carbon nanotubes using standard lithographic techniques. In this work, aligned nanotubes are partially suspended over trenches made by chemical etching. Strain-induced downshifts as high as 31 cm−1 are observed in the Raman spectra, roughly corresponding to 1.1% strain. We also observe significant shifts in the resonant transition energy Eii and an...

\Ripple Down Rules (RDR)" Method is one of the promising approaches to directly acquire and encode knowledge from human experts. It requires data to be supplied incrementally to the knowledge-base being constructed and new piece of knowledge is added as an exception to the existing knowledge. Because of this patching principle, the knowledge acquired strongly depends on what is given as the def...

keratoderma is a group of disorders characterized by abnormal thickening of skin. acquired palmar keratoderma has many underlying causes. the association of thyroid disease and palmar keratoderma rarely reported. hypothyroidism, although very rare association, must be suspected in patients with acquired ppk, particularly when it occurs in setting of systemic symptoms or predisposing conditions....

conclusions the current study indicated that h. pylori infection occurs at a higher rate in patients with down syndrome and mental retardation. this may provide more reasons to control the transmission of h. pylori among them. results the differences between the groups were compared by t-test and x2 test. seropositivity for h. pylori was significantly higher in patients with down syndrome and m...

Objective: This study aimed to evaluate the quality of life and related factors in mothers of children with Down syndrome. Methods: The study method was correlation-survey (sectional). Sampling was based on the available population. The research population consisted of all mothers of children with Down syndrome referred to the Down Syndrome Center: out of them 70 mothers of chil...

we report three cases of asymptomatic celiac disease identified in children with down syndrome after being screened at around twenty-four months of age.  these cases raise the question as to what age is screening for celiac disease indicated in a child with down syndrome and no symptoms.

chronic lymphocytic leukaemia (cll) is the most common b-cell malignancy in the western world and exists as subtypes with very different clinical courses. myeloid cell leukemia 1 (mcl-1) is one member of bcl-2 family proteins that has been shown to be expressed in various tissues and malignant cells, including cll, where its expression is significantly associated with a failure to achieve compl...
