In this paper, MM-Model is presented for real-time simulation of 3D deformable objects on both global level and local region. This model consists of a deformable centerline and dynamic surface reconstruction mechanism based on Mass-Spring and Medial-Representation respectively. When a relatively small force is applied on the object the model works in the same way as the traditional Mass-Spring....

There is a general consensus in the European and American guidelines for pediatric hypertension that children from 3 years of age and older who are seen in a medical setting should have their blood pressure (BP) measured. This is because hypertension in children and adolescents has become an emerging public health issue, with increasing prevalence mainly driven by the obesity epidemic in this p...

Blood is fundamental in several care treatments and surgeries, and plays a crucial role in the health care system. It is a limited resource, as it can be produced only by donors and its shelf life is short; thus, the blood donation (BD) system aims at providing adequate supply of blood bags to transfusion centers and hospitals. An effective collection of blood bags from donors is fundamental fo...

Several techniques exist for index reduction and consistent initialization of higher index DAEs. Many such techniques change the original set of equations by differentiation, substitution, and/or introduction of new variables. This paper introduces substitute equations as a new language element. By means of a substitute equation, the value of a continuous variable or its time derivative is spec...

A growing antivaccine movement in Canada and elsewhere is hearing more about an unproven homeopathic therapy, 'nosodes', as an alternative to routine vaccines. The present statement defines nosodes and describes limitations for their use in children. There is scant evidence in the medical literature for either the efficacy or safety of nosodes, which have not been well studied for the preventio...

ATROPINE, perhaps the drug most used in ophthalmology, is prone to cause contact-irritation, often at a time when continued mydriasis is essential, in patients on long-term treatment. Unfortunately, most substitutes are less effective in producing mydriasis, and not infrequently contact-irritation is developed to these substitutes in rapid succession. Lachescine (E3) was developed in Great Brit...

valvuloplasty can be performed safely and with satisfactory results in over 85% of these patients. It is also possible that repeat PMV can be performed in these patients with acceptable risks and results. In our own single centre experience in about 390 procedures repeat percutaneous balloon valvuloplasty was performed in 17 cases (mean age 65 13 years) without any increase in the rate of acute...
