We analyzed p53 cDNA and genomic clones from a variety of normal transformed cells. Sequence analysis these revealed that amino acid residue 72 can be an arginine, proline, or cysteine. This single codon difference results in electrophoretically distinct forms human seen
Results of experiments with thermocapillary flow in shallow liquid layers heated from the side are presented. The fluid has Prandtl number 17 and main configuration investigated is an annular gap to avoid side-wall effects. depth d was d≤3.00 mm have negligible buoyancy Various instabilities been observed. At a Marangoni M≂6⋅102, transition steady multicellular occurred. convection cells longitudinal rolls embedded all rotating same direction. M≂3⋅103, time-dependent states (t) Two different...

A method useful in the production of streams uniform-sized liquid droplets, which are uniformly spaced relative to one another, is discussed. An extension for single droplets known size also given. The based on principle that a cylinder dynamically unstable under action surface tension. capillary wave launched onto or jet selects particular mode instability. process disintegration thereby regularized extent extremely uniform result. controlled by inside diameter tube through flows, and...
Liquid motion is often observed when an electric field applied to a dielectric liquid. An analysis of the steady cellular convection which results charge injected uniformly into free surface film insulating liquid discussed. The initial, steady-state current space-charge-limited. method exchange stabilities assumed be valid; velocity and potential perturbations on initial state lead characteristic equation determines conditions for onset instability. This seventh order has nonconstant...
The Lagrange Equations of Motion are written in generalized coordinates which describe small departures from the spherical equilibrium configuration a conducting liquid droplet. It is initially assumed that actual shape differs only very slightly sphere. equation representing surface is, then, as series zonal harmonics coefficients shown to be normal frequency oscillation depend on total charge droplet such manner for all values below certain limit, real. For above imaginary; and, thus,...
A method for producing a stream of uniform-sized liquid droplets and individual is discussed in detail. The based on the principle that cylinder (jet) dynamically unstable under action surface tension. When capillary wave prescribed wavelength applied to jet, jet will disintegrate into droplets. Since droplet size depends tube through which flows, can be easily varied. piezoelectric transducer used produce jet. apparatus range between 25 350 μm radius. unique precisely controlled produced at will.
A capillary wave of the appropriate wavelength will cause a jet to break up into stream uniform-sized droplets. In this paper, theoretical expression for droplet size, radius, and spacing in terms parameters applied frequency is derived verified experimentally. For given radius velocity, size can be varied from its minimum value, rmin, approximately 1.6rmin by varying driving frequency. Also, charge on droplets resulting disintegration charged shown agree with measured value charge.
Unidirectional sliding experiments with polished and laser textured steel surfaces were carried out to investigate the effects of different area densities, aspect ratios dimple arrangements. The system was lubricated Polyalphaolefin (PAO) at 100 °C contact pressure 3 MPa. For measuring Stribeck curves, speed controlled between 40 2000 mm/s. density varied 5% 30%, lowest friction values found for 10%. Aspect ranging from 0.02 0.2 investigated 0.1 measured. arrangements tested cubic, hexagonal...
The extracellular domain of the human interleukin‐6 (IL‐6) receptor, comprising 339 amino acids following signal peptide, has been expressed in baculovirus‐infected insect cells (Sf158). When soluble receptor secreted into culture medium was purified by affinity chromatography, using IL‐6 immobilized on Sepharose, 6 mg isolated from 1 l conditioned Sf158 suspension cultures. A molar absorption coefficient 9.3 × 10 4 · mol −1 cm calculated ultraviolet spectrum receptor. After SDS/PAGE and...

Cross-laminated timber (CLT) products are gaining popularity in the North American market and being used midrise wood buildings, particular, shearwall applications. Shearwalls provide resistance to lateral loads such as wind earthquake loads, therefore it is important gain a better understanding of behavior CLT systems during events. This paper focused on seismic performance connections between panels foundation. very stiff energy dissipation accomplished by connections. A literature review...
Reducing friction forces is a major challenge in many engineering applications involving moving parts. For the past 50 years, morphological texturing of surfaces for improving tribological properties has been investigated. Only recently, application biologically inspired surface features, like scales found on lizards and snakes, come to attention tribologists. Here, we present results lubricated unlubricated performance scale-like textures applied with laser light bearing steel pins. These...
Abstract Durch die Kaltbearbeitung werden nicht nur elastischen Eigenschaften der Metalle stark verändert, sondern auch chemischen. Das galvanische Potential wird unedler, Auflösungsgeschwindigkeit nimmt zu (Eisen), Farbe gewisser Goldlegierungen mit Silber oder Kupfer durch Walzen gelber und Einwirkungsgrenzen verschiedener chemischer Agenzien auf Gold‐Silber‐ Gold‐Kupferlegierungen höherem Goldgehalt verschoben.
