Charter Schools That Do Not Suspend
… that are academically successful and do not suspend or expel their students, specifically their African-American and Latino male students. I filter this exploration through my own perspective as the former principal of a small urban charter school like the ones I study in this project. I …

Using money to suspend heavy or fragile objects
The author suspends a 700-lb steel money safe from the ceiling, using ropes constructed from approximately 10,000 United States $1 bills. The role of money in this artwork is compared and contrasted with the role of money in artworks by other contemporary artists. It is noted that the presence of …

An Investigation of Methods to Homogeneously Entrain and Suspend Abrasive Particles in a Low Pressure Dental Water Jet
… methods have been proposed to entrain and suspend particles in a high pressure water jet system. The abrasive particles can be entrained before the water is pressurized, while the water is being pressurized, or after the water jets stream exits the pressurized system. Each method has its …

Effect of impeller submergence on power dissipation and solids suspension in mixing systems equipped with pitch-blade turbines
… must be stopped when the solids are no longer suspended. In this work, the minimum agitation to suspend solids (Njs) when the liquid level was lowered, and the impeller submergence S_b changed as a result were determined for the case of a six-blade, pitch-blade turbine (6-PBT) impeller. The …

Mixing for Suspension of Solids
The power required to suspend several solid materials in a circular fully baffled tank was studied. A single 45 degree pitched blade impeller was used to produce downward flow. Sand, wheat straw, corn stover, activated carbon, and activated carbon-sand mixture were studied in this system. Several …

This is a Present from a Small, Distant World
… media ecologies as artificial landscapes which suspend us from the natural. In a dissection of the dualisms of man and nature, and progress and sustainability, I create microcosms of our detached condition.</p>

Chopper stabilization in analog multipliers
… calibration typically forces the multiplier to suspend normal operation while the offsets are being measured. In this thesis, a technique for continuously regulating offset in multipliers is studied in isolation. Chopper stabilization, a technique long used in DC amplifiers, is applied to analog …

Shooting device for free-surface impact studies
… to propel the ball and an electromagnet to suspend the ball before shooting. This shooting mechanism uses magnetic balls of diameter 1 inch and can achieve velocities of 278 m/s when located 1 m above the free surface. The adaptability of the mechanism to other downward shooting situations …

Detection of Floating Grains in DC Aluminum Casting
… and by recent work using a turbulent jet to suspend solute-poor grains and minimize macrosegregation.1,2 Experiments in this study were designed to sample grains from the mushy region of two ingots, one cast by the standard method and another stirred with a turbulent jet. Measurements of …

Pyxidis Echo Lacuna
… thesis is to provide a space for the viewer to suspend the exterior world and move into a space where he or she finds a line of questioning and a cyclic experience that ultimately leads to self-reflection. The microcosm and macrocosm enlarged and reduced, respectively, to human scale, allow one …

Sonoelectrochemical synthesis of submicron metal powders
… applied to an electrochemical cell to create and suspend particles in the electrolyte. The pulsed technique largely separates the particle morphology defining physical action of electrochemistry and ultrasound. Despite the large body of work characterizing the pulsed method, surprisingly little is …

Fabrication of aligned nanofiber yarns, mats and isolation of single nanofiber in electrospinning
… and water. In both the techniques the nanofibers suspend over the gap in a highly oriented manner, and they can be easily transferred onto a substrate for further applications. Since the fibers generated by electrospinning are in micrometer and nanometer scale, it is very complex to isolate and …

Towards a trans-Caribbean poetics: A new aesthetic of power and resistance
… of visual and linguistic disruption in order to suspend normative representations of Caribbean identity. Trans-Caribbean Poetics is trans-continental, fragmentary, personal, relational and multilingual and suggests a plausible model to analyze discursive relations in a transnational context.

Mathematical Models of Quiescent Solar Prominences
<p>Magnetic fields in the solar atmosphere suspend and insulate dense regions of cool plasma known as prominences. The convection zone may be the mechanism that both generates and expels this magnetic flux through the photosphere in order to make these formations possible. The connection is …

Rotordynamic assessment for a permanent magnet synchronous motor
… a cantilevered rotor structure was pro- posed to suspend the rotor around the stator. This architecture introduces significant rotordynamic challenges, one of which is the “trunnion effect,” a rotordynamic effect uncommon in traditional electric machines. This effect was identified when a …

Jet processing of direct chill cast aluminum ingots
… we propose the use of a turbulent jet to re-suspend the avalanching grains. An analytical expression is derived in order to optimize the dimension of the jet with the goal of minimizing centerline segregation. We then performed a series of experiments in order to validate the analytical …

The impact of weaknesses in the Urban Councils Act on efficient and effective service delivery in urban local councils in Zimbabwe
… powers to give directions on matters of policy, suspend, reverse, or rescind council resolutions. There is no legal authority to check and balance the unfettered powers of the minister. Poor service delivery may be attributed in part to the unfettered powers of the minister. Secondly, UCs do not …

Montage As A Participatory System: Interactions with the Moving Image
… of real-time interaction. If the task is not to suspend but encourage disbelief as a condition in the user, how can this be approached as a design problem? In the attempt to build a series of design projects suggesting open architectures for the moving image, might a variety of (pre-digital) …

Minimum agitation speed for solid suspension and mixing time in a torispherical -bottomed pharmaceutical stirred tank under different baffling conditions
The minimum agitation speed, NS, required to just suspend solid particles dispersed in water was experimentally determined in this work for a glass-lined type of mixing tank provided with a torispherical bottom and agitated with a retreat-blade impeller under different baffling configurations. Ns …
