Interaction of Drops falling into Volatile Liquids
… iron, nickel, magnox and sodium chloride. Photographic techniques were used to observe the MCIs and in addition, a hydrophone has monitored pressure fluctuations in the coolant on the small scale. The photographic techniques were three-fold: high speed photography, stroboscopically …

Applications of air photo interpretation techniques in the Langebaan area, S. Africa
… as is a short discussion on the merits of air photographic techniques.

A Study of Mass Transfer from Large Oscillating Drops:2 Volumes
… by the Messinger iodoform method (193). Photographic techniques were developed to record the frequency of droplet oscillation, area change, amplitude and vertical velocities with high speed cine photography. High concentrations of acetone were employed in the dispersed phase, i.e. up to …

Distributions across the plume of transverse liquid and slurry jets in supersonic airflow
… data indicate that correlations developed from photographic techniques are inadequate in determining the jet penetration and width of liquid and slurry jets. The slurry jet showed substantial phase separation. A 30% mass-loaded slurry of 1-5 µm silicon dioxide particles mixed with water was …

Defamiliarising the Familiar: The Distorted Body in Photography
In the context of my photographic practice, this practice-based research investigates visual distortions of the human body through the application of techniques available to photography within a studio environment. Despite an understanding of the motivations and contextual reasoning for why …

Microbial Ecology of a Bat Guano Community
… plate, pit-fall trap, direction observation, and photographic techniques on guano of various ages. Fresh guano is initially dominated in number and biomass by a bacterial flora primarily of enteric origin. Older guano remains numerically dominated by bacteria but fungi dominate in the biomass …

Synthetic and structural studies on early transition metal siloxides
… crystals Cp2Zr(OSiPh3h were studied using X-ray photographic techniques. They crystallise in the monoclinic system with a = 35. 7, b = 10.4, c = 21.1 A, f3 = 97.7 °, V= 7763 A3. A full crystal structure analysis was not possible due to failure of the diffractometer software to locate the …

The hydrodynamic behaviour and mass transfer characteristics of single droplets in a pulsed sieve plate column
… - acetone - distilled water. Existing photographic techniques for following and recording the droplet behaviour, and for observing the parameters of the pulse and the pulse shape were further developed and improved. A unique illumination technique was developed by which a moving droplet …

Historical changes on rocky shores in the Western Cape, as revealed by repeat photography
… taken at low tide and indeed the most effective photographic sampling is carried out during spring low tides , when the greatest area of intertidal habitat is exposed. Capturing images during these brief windows often complicates large-scale spatial studies, especially with limited resources …

Picturing irony: Making a visual case-study from the work of Camus
… theoretical framework, drawing from literary and photographic irony, in conjunction with a practice-led research methodology. The creative project, Clint’s Last Road Trip (2014), traces the 1000 kilometre journey that my brother’s body made from his death until his cremation. It depicts the …

Effect of physical properties on break-up and atomization of liquid jets in a supersonic crossflow
… employed a short exposure (9 x 10⁻⁹ sec.) photographic technique to establish the instantaneous structure of the jet in the crossflow. Relatively long exposure (10⁻³ sec.) photographs were obtained to study the time averaged behavior of the jet in the crossflow. Two multi-exposure …

Dense-phase pneumatic transport of cohesionless solids
… flow to dense-phase plug flow. High-speed photographic techniques have been used to document the flow patterns in both the horizontal and vertical sections. Pressure drop measurements across a 70 cm test section have been coordinated with the film work. At the higher superficial air …

Traditions and Transformations in the Work of Adál: Surrealism, <i>El sainete</i>, and Spanglish
… is firmly grounded in established photographic techniques as well as social justice movements of the 1960s. It is also informed by eighteenth and nineteenth century Puerto Rican literary and theater traditions such as the <em>sainete</em>. These traditions are at the root of Puerto …

Behaviour of Bubble Columns with Two and Three Phases
… were characterised by visual observations, photographic techniques and qualitative analysis: The "stimulus-response" technique was used for mixing studies. In all cases, high flow rates corresponding to regimes of industrial importance were investigated. Experimental results were …

Particle ejection system : target particle recovery using a transient water jet
… angle and the force duration. Acoustical techniques in air are unsuitable as ejection force mechanisms. A water jet is proposed to meets these requirements. This water jet is caused by an electrical discharge in a liquid cavity. This produces a weak shock wave which is focused by the …

Elizabeth Bishop's Photographic Poetics: The Peripheral Vision
Elizabeth Bishop‘s poetics of description has been the object of numerous critical studies. These most often focus on questions of observation, positioning, framing, and refer to Bishop‘s aesthetics as ―optical poetics.‖ Instead of simply using optical vocabulary to talk about her work, I …
