D@teries

Project beats from the pulse. A gallery beating with 1000s of pulses read and recorded from visitors to the gallery. Each pulsating entry is pumped into a colour coded algorithm which simulates heart beats and reacts both to each additional beat to the visualisation and to sensory energy from the interactions within the space. Central to the installation is a 'plasma' sculpture. With each additional pulse pumping into the sculpture , the 'Plasma' sculpture evolves and transforms. Studying the viscoelastic properties of blood flowing using a heart pump , blood value simulation.[1] For D@teries plasma - from a plasma bank or representations - recycles through the sculpture. the artworks conceptuall emphasis is to provoke the audience to a discourse on the precious and vital plasma as resource for scientific research rather than an aesthetic commodity. [2] The plasma is pumped into a cold box at the temperature of the body and the temperature of the cold box is set at an optimum temperature as part of the plasma preparation process. As the plasma is pumped into the cold box the hot visceral liquid properties change, drip , coagulate forming a continuously evolving form suspended in the coolbox. the plasma recycle using plasma bank extraction nd cleaning processes.[3] Mark Quinn has repeatedly used blood frozen through his self portrait analogies from 1998 and revised periodically. [4] The study of the viscoelastic properties of blood are important for the development of cardiovascular prosthetic devices such as heart valves and blood pumps, the understanding of pulsating blood flow in complex geometries.. primarily analog representatives for blood and plasma include glycerin and water which provides a representation of viscosity and inertial effects but lacks the elastic properties of real bloodAnalog representatives; frequently used in experimental simulations include aqueous solution of Xanthan gum and glycerin, the experiment conditions don't match the viscosity and elastic components of the complex viscosity of blood. For the D@teries series the contextual component of the 'plasma' is as a representation and metaphor for the vitality of blood , flowing , re-generating, life force, visceral substance. [5] Only a specific quantity of plasma is pumped through the cool box. The plasma an anonymous donation (paid for). Considering the prioritis for scientific plasma donations the qquantity used


both specified , regulated and recycled, and used only in collaboration with scientific research, fellowships, plasma and heart foundation endorsement and collaboration., [6] Installation Specifics As visitors enter the gallery a pulse reading is taken from a simple medical quality pulse tracking device which can monitor values incl. pulse , reactions, heat, flow, oximeter, experimental shear stresses - app and software that records and analysis relevant phenomena [6] Each visitor is given an anonymous barcode their heartbeat reading which they track on the project website. Optional low shear rate model constants are used to experiment with data over several sets of constants. The readings are clinical records and accentuate the potential for importance of non invasive medical research. Highlighting the discourse on open access to private medical data and civil rights. At the preparatory phase medical details of relevant received data, plasma properties or representatives are based on research, theoretical. For the installation , scientists, design and development researchers - with collaboration with Trinity College fellows, labs and other research labs and open source labs would have consultation on the form and extent of scientific research associated with the trans media generative artwork. Scientific , medical and lab consultants the are connectable at the preparatory phase are HIV ( UCL) medical research, GP , Neuroscience(UCL/ Welcome Trust London), Hackspace open source lab CAM (GENOME software workshop and hack lab). the project context is specific to The Trinity College call for 'blood'! Analysing the context and technical requirements of the installation , the piece requires a framework and support of fellowship research (for further science / art research structure and research). D@series is contextually 'nodal' within an extended rhizomic structure base. The installation the apparatus and form requires to simulate and inspire discourse on the subject and experimental form. The extent to which the artwork and form can inform as a scientific research is dependent on scientific and lab contribution and funding. The only aspect of the installation that has scientific basis is the pulse tracker (with collaboration with a research experiment nd fellowship on heart rate, pulse analytics and medical research data analysis. However the project and form has potential for the artwork to initiate generative research ;extended satellite research, evolving creative lab condition experimentation.[7] areas of discourse on blood - plasma, tec, 3D printing , shear constants algorithms, flow Many conditions, eg. sickle cell disease, reduce red blood cell elasticity which makes them less deformable. Red blood cells with reduced deformability have increasing impedance to flow, leading to an increase in red blood cell aggregation and reduction in oxygen saturation which can lead to further complications. The presence of cells with diminished deformability, as is the case


in sickle cell disease, tends to inhibit the formation of plasma layers and by measuring the viscoelasticity, the degree of inhibition can be quantified. early studies used properties found in steady blood flow to derive properties for unsteady flow situations. Technical and scientific research actively accelerate advancement of the mechanical properties of blood. The data is recorded retrieved, archived and analysed with a specific scientific research fellowship either heart or plasma research and collaborators, sponsors and research are credited on all installation material and promotion. Any abnormalities of heart beat pulse are immediately identified (perhaps onsite!) and the barcode tracked through the database and the barcode holder notified immediately! The pulses are emitted as colour coded abstract visualisations that fill the senses and the gallery space with all the connotations a red hot beating spatial ether infer ; conceptual life flow, interactive beats, ; blood, art, divinity (separate concept paper). Technical and Illustration The installation is set as medical experimentation conditions, with consideration to otimumum temperatures for blood plasma and cool box to accurately simulate the conditions required for blood, blood flow, representation of properties and chemical reactions for analysis The installation sculpture dimensions are specific to the Trinity College Gallery Space. Any dimensions sited are for experimental conditions accuracy and illustration but specific to the gallery Space. Further technical conditions are to display the sculpture viewable from a window that the gallery Space is lit with ultra violet or experiment conditions lighting at night. The sculpture is in situ for the 3 month duration of the project and designed to recycle mechanically. however technician (backspace volunteer) is required to check , test, tweek the installation. Including replenishing plasma (representative) and valves . Bluetooth wireless workshop events have also popped -up in response to rapid (accelerated) open source app development , teaching all software , coding and for their products and devices which include top end market tracking devices and software compatible for pulse monitor devices. The installation sculpture could form a series, a sculpture from each week, or month could form displays around the gallery and the centralsculpture active valve pump. Additional costs apply for active cool boxes for additional 3 - 12 cool boxes. The series is visualisation example viable only with additional sponsorship funding . As the installation is transcient and only exists for the duration of the project 3D sculpture forms could be made of the plasma sculpture ( from data ) as tangible visceral forrms for the Gallery collection (additional costs).


Budget The budget calculations are estimates but takeinto account, technical design, preparation, installation, software and research. Technicians for the preparation and maintenance of the installation for the duration of the exhibition are Hackspace (Hackspace London/ per site location) or Trinity College lab volunteers (paid, volunteer rate). Hackspace volunteers include Hackspace membership. funding - volunteer pay for pro. tec support generously offered . sponsors in addition to the award.

It makes up about 55% of the body's total blood volume.[1] It is the intravascular fluid part of extracellular fluid (all body fluid outside of cells). It is mostly water (up to 95% by volume), and contains dissolved proteins (6-8%) (i.e.—albumins, globulins, and fibrinogen),[2] glucose, clotting factors, electrolytes (Na+, Ca2+, Mg2+, HCO3-, Cl-, etc.), hormones, and carbon dioxide (plasma being the main medium for excretory product transportation). Plasma also serves as the protein reserve of the human body. It plays a vital role in an intravascular osmotic effect that keeps electrolytes in balanced form and protects the body from infection and other blood disorders.


Blood plasma is prepared by spinning a tube of fresh blood containing an anticoagulant in a centrifuge until the blood cells fall to the bottom of the tube. The blood plasma is then poured or drawn off.[4] Blood plasma has a density of approximately 1025 kg/m3, or 1.025 g/ml.[5]

More specifically, it measures what percentage of hemoglobin, the protein in blood that carries oxygen, is loaded. Acceptable normal ranges for patients without pulmonary pathology are from 95 to 99 percent. For a patient breathing room air at or near sea level, an estimate of arterial pO2 can be made from the blood-oxygen monitor "saturation of peripheral oxygen" (SpO2) reading. Pulse oximetry is a particularly convenient noninvasive measurement method. Typically it utilizes a processor and a pair of small light-emitting diodes (LEDs) facing a photodiode through a translucent part of the patient's body, usually a fingertip or an earlobe. One LED is red, with wavelength of 660 nm, and the other is infrared with a wavelength of 940 nm. Absorption of light at these wavelengths differs significantly between blood loaded with oxygen and blood lacking oxygen. Oxygenated hemoglobin absorbs more infrared light and allows more red light to pass through. Deoxygenated hemoglobin allows more infrared light to pass through and absorbs more red light. The LEDs flash about thirty times per second.[32] The photodiode measures the amount of light that is transmitted (in other words, that is not absorbed). The measurement fluctuates in time because the amount of arterial blood that is present increases (literally pulses) with each heartbeat. By subtracting the minimum transmitted light from the peak transmitted light in each wavelength, the effects of other tissues is corrected for.[33] The ratio of the red light measurement to the infrared light measurement is then calculated by the processor (which represents the ratio of oxygenated hemoglobin to deoxygenated hemoglobin), and this ratio is then converted to SpO2 by the processor via a lookup table.
