  • Increased miniaturization of the integrated chip has largely been responsible for the rapid advances in semiconductor device performance, driving the industry’s growth over the past decade(s). Soon the minimum feature size in a typical integrated circuit device will be well below 100 nm. At these dimensions, interlayers with extremely low dielectric constants (k) are imperative to reduce the cross-talk between adjacent lines and also enhance device speed. State-of-the-art non-porous, silicon-based low-k dielectric materials have k values on the order of 2.7....

  • Stresses in thin cylinders If the wall thickness is less than about 7% of the inner diameter then the cylinder may be treated as a thin one. Thin walled cylinders are used as boiler shells, pressure tanks, pipes and in other low pressure processing equipments. In general three types of stresses are developed in pressure cylinders viz. circumferential or hoop stress, longitudinal stress in closed end cylinders and radial stresses.

  • It is essential to monitor intracranial pressure, CPP, and brain oxygenation during ventilatory support in the patients with traumatic brain injury. Brain oxygenation monitoring technics are jugular venous saturation monitoring, near-infrared spectroscopy and microdialysis catheters. Availability and cost of these devices are limiting factors to their use. The studies on brain trauma patients shows that there is no proven mortality benefit in continuous ICP monitoring.

  • I recommend a dynamically stirred, two-pump, high-pressure mixing system. If, on the other hand, you’ll mainly be doing scouting gradients, dial-a-mix isocratics, and the occasional uncomplicated gradient, the low-pressure mixing system would be excellent and save you about $4,000. This system has the advantage of giving you three- or four-solvent capability, which would be of advantage in scouting and automated wash-out, but it requires continuous, inert gas solvent degassing.

  • The lung has a unique vascular structure and function; it has low pressure, low resistance circulation with a highly compliant system which accommodates the same amount of flow as the systemic circulation. In addition, pulmonary and systemic vasculatures have divergent responses to various stimuli. For example, pulmonary arteries constrict in the setting of hypoxia, while systemic circulation dilates. This is due to distinctive developmental characteristics, anatomic and histological structure, as well as physiological properties.

  • Shiitake mushroom contains several therapeutic actions such as antioxidant and antimicrobial properties, carried by the diversity of its components. In the present work, extracts from shiitake mushroom were obtained using different extraction techniques: high-pressure operations and low-pressure methods. The high-pressure technique was applied to obtain shiitake extracts using pure CO2 and CO2 with co-solvent in pressures up to 30 MPa.

  • Typically, the response rate in a direct marketing campaign is low. It is not unusual to see a response rate of less than 5%. As a result, the size of the “responder” class tends to be much smaller than the size of the “non-responder” class. Such situation where the class distribution is significantly skewed toward one of the classes is commonly known as the class imbalance problem [Jap00]. The more interesting class is usually the smaller class.

When it comes to the chemistry and physics of carbon, as reflected by the authorship in this series since its inception 40 years ago, globalization (a popular term among today’s politicians and economists) has always been the rule rather than the exception or a recent trend. If anything, The New York Times editorial of May 7, 2004 is indeed correct in its conclusion that “the United States . . .

  • Harrison's Internal Medicine Chapter 118. Infective Endocarditis Infective Endocarditis: Introduction The prototypic lesion of infective endocarditis, the vegetation (Fig. 118-1), is a mass of platelets, fibrin, microcolonies of microorganisms, and scant inflammatory cells. Infection most commonly involves heart valves (either native or prosthetic) but may also occur on the low-pressure side of the ventricular septum at the site of a defect, on the mural endocardium where it is damaged by aberrant jets of blood or foreign bodies, or on intracardiac devices themselves.

  • Ageing tends to be associated with a growing burden of disease and prolonged heavy drinking is itself a cause of health problems such as liver disease, raised blood pressure, and some forms of cancer. Alcohol misuse may also lead to an increased likelihood of falls, incontinence, cognitive impairment, hypothermia and self-neglect. These sorts of problems may be regarded by health professionals and members of the family merely as signs of ageing.

  • To address the first question, we analyzed data from three Education databases and identified schools that provided loans through either the Direct Loan Program or FFELP in each school year from 1994-95 to 2001-02. To address the second question, we surveyed financial aid officials at schools that participated in the Direct Loan Program in 2001-02, of whom 57 percent responded to our survey. 2 We also surveyed schools that had participated in the program for at least one school year from 1994-95 to 2000-01 but did not participate in 2001-02.
