  • Dedicated to the memory of V. I. Gurarii Abstract We prove that if X is a separable infinite dimensional Banach space then its isomorphism class has infinite diameter with respect to the Banach-Mazur distance. One step in the proof is to show that if X is elastic then X contains an isomorph of c0 .

  • Difficulty in addressing contamination in low permeability soils may be alleviated to some degree by controlled pneumatic or hydraulic fracturing of the soil. However, engineered hydraulic fractures generally cannot be spaced more closely than about 5 feet, which means that chemical oxidants must still penetrate a substantial thickness of low permeability soil to come into contact with the contamination. Deep soil mixing with large diameter drill augers is the most effective method currently available to increase contact between adsorbed contaminants and the oxidants.

  • Abstract. The classical Heron problem states: on a given straight line in the plane, find a point C such that the sum of the distances from C to the given points A and B is minimal. This problem can be solved using standard geometry or differential calculus. In the light of modern convex analysis, we are able to investigate more general versions of this problem. In this paper we propose and solve the following problem: on a given nonempty closed convex subset of Rs , find a point such that the sum of the distances from that point to n given nonempty closed convex subsets of...

Since the velocity ratio is the inverse ratio of the diameters of driving and driven pulleys, therefore the pulley diameters should be carefully selected in order to have a desired velocity ratio.

  • Measurement of macro-geometric characteristic variables involves the acquisition of features of geometric elements that are defined in design by dimensions and tolerances for dimensional, form, and positional deviations (Figure 3.1-1). The term ‘dimension’ refers both to the diameter of rotationally symmetrical workpieces and to distances and angles between planes and straight lines and to cone angles. The sensors used for measurement can be classified according to the method used to acquire the measured value into mechanical, electrical, and optoelectronic sensors....

  • The art of imaging blood vessels in the human body is called angiography. Since its inception, physicians have benefited from the field of angiography imaging. This has helped them to diagnostically treat patients with various kinds of vascular diseases. Recently, because of the technology growth in fields of acquisition techniques, such as magnetic resonance, computer tomography, digital subtraction angiography, and ultrasound, the vascular imaging research community has become very interested. But acquisition is just one side of the coin.

  • Labor is the normal process of coordinated, effective involuntary uterine contractions that lead to progressive cervical effacement and dilatation and descent and delivery of the newborn and placenta. Near its termination, labor may be augmented by voluntary bearing-down efforts to assist in delivery of the conceptus. False labor is characterized by irregular (both in interval and duration), brief contractions without fundal dominance, cervical change, or a lower station of the fetal vertex or breech.

  • Paso del Norte’s growth has had serious environmental consequences, particularly for air quality, which is the worst on the U.S.–Mexico border. Ciudad Juárez exceeds national ambient air quality standards (official norms) for ozone, carbon monoxide, and particulate matter less than 10 microns in diameter (PM10), and El Paso exceeds national ambient air quality standards for ozone, PM10, and carbon monoxide. An overwhelming body of evidence links such air pollution to respiratory and cardiovascular disease, and to premature mortality (U.S. EPA 1999).

  • Semi-intact cells are cells whose plasma membrane has been permeabilized with detergent or toxins, and can be referred to as “cell-type test tubes” (Fig. 1). We use a bacterial poreforming toxin, streptolysin O (SLO), to permeabilize the cells. At 4℃, SLO binds to cholesterol in plasma membranes. At warmer temperatures, SLO assembles to form amphiphilic oligomers, which results in the generation of small, stable transmembrane pores (Bhakdi et al., 1985).
