For faster, smaller, and higher performance integrated circuits, a low dielectric constant insulator is required to replace silicon dioxide. Here the properties of new dielectric—SiLK resin, solution low-molecular-weight aromatic thermosetting polymer—are reviewed examples its application in fabrication interconnect structures, such as one shown Figure, are given.

Clinical defined as having at least partial pharmacist full-time equivalent specifically devoted purpose direct involvement patient care. Infections...

With a background of experimental studies on macroporous biphasic calcium phosphate (MBCP) in canine spine fusion, MBCP was investigated 11− to 18-year-old patients with scoliosis treated by spinal fusion. Twelve cases were chosen for whom enough bone graft difficult obtain (severe neurologic and osteogenesis imperfecta). blocks used combination specific strong fixation (Cotrel-Dubousset instrumentation). Clinical roentgenogram assessments performed up 24 months. In two cases, biopsies...

The purpose of this study is to evaluate the potential decalcified freeze-dried bone allograft (DFDBA) combined with a barrier material in treatment human molar furcation defects (experimental) as compared technique alone (control). Fifteen pairs Class II or III invasion comprised group. Measurements calibrated periodontal probes were made determine soft tissue recession, probing depth, and attachment levels. Defects from each pair randomly selected be treated an expanded...

We describe and explore a new general transmission line model that describes the viscoelastic characteristics of thin films in terms their shear moduli. The contains within it commonly used lumped-elementmodel as limiting case, we delineate conditions under which thesimpler lumped-element can be applied without significant error. apply our analysis to interpretation crystal impedance spectra acquired dynamically during electrodeposition poly(2,2′-bithiophene) (PBT) conducting polymer films....

The results of the researches Smith and Engle (1927), Zondek Aschheim (1927) many others have demonstrated dependence function gonad upon anterior pituitary gland. One very characteristic quality gonad, ovary in particular, is its rhythmical activity. This suggests a parallel activity probability pituitary-gonadal interrelationship. Such relationship was first suggested by (1929a) publication his study on gonad-stimulating hormones gonadectomized rat Avhich he stated that release complex...

Abstract Objective The advent of new technologies has made it possible to explore alternative ventilator manufacturing meet the worldwide shortfall for mechanical ventilators especially in pandemics. We describe a method using rapid prototyping create an electro-mechanical cost effective, timely manner and provide results testing vitro–in vivo model.

Meperidine-associated central nervous system (CNS) excitatory toxicities are believed to be caused by accumulation of the active metabolite normeperidine. Normeperidine is eliminated kidneys and accumulates in patients with renal insufficiency, sickle cell disease, cancer. In cirrhosis, metabolism meperidine decreased, leading parent drug possible CNS depressive effects similar hepatic encephalopathy. Although elimination normeperidine decreased as well these patients, ratio generally low,...
