An improved vaseline gap voltage clamp for skeletal muscle fibers. (1/44)

A Vaseline gap potentiometric recording and voltage clamp method is developed for frog skeletal muscle fibers. The method is based on the Frankenhaeuser-Dodge voltage clamp for myelinated nerve with modifications to improve the frequency response, to compensate for external series resistance, and to compensate for the complex impedance of the current-passing pathway. Fragments of single muscle fibers are plucked from the semitendinosus muscle and mounted while depolarized by a solution like CsF. After Vaseline seals are formed between fluid pools, the fiber ends are cut once again, the central region is rinsed with Ringer solution, and the feedback amplifiers are turned on. Errors in the potential and current records are assessed by direct measurements with microelectrodes. The passive properties of the preparation are simulated by the "disk" equivalent circuit for the transverse tubular system and the derived parameters are similar to previous measurements with microelectrodes. Action potentials at 5 degrees C are long because of the absence of delayed rectification. Their shape is approximately simulated by solving the disk model with sodium permeability in the surface and tubular membranes. Voltage clamp currents consist primarily of capacity currents and sodium currents. The peak inward sodium current density at 5 degrees C is 3.7 mA/cm2. At 5 degrees C the sodium currents are smoothly graded with increasing depolarization and free of notches suggesting good control of the surface membrane. At higher temperatures a small, late extra inward current appears for small depolarizations that has the properties expected for excitation in the transverse tubular system. Comparison of recorded currents with simulations shows that while the transverse tubular system has regenerative sodium currents, they are too small to make important errors in the total current recorded at the surface under voltage clamp at low temperature. The tubules are definitely not under voltage clamp control.  (+info)

The precision of a special purpose analog computer in clinical cardiac output determination. (2/44)

Three hundred dye-dilution curves taken during our first year of clinical experience with the Waters CO-4 cardiac output computer were analyzed to estimate the errors involved in its use. Provided that calibration is accurate and 5.0 mg of dye are injected for each curve, then the percentage standard deviation of measurement using this computer is about 8.7%. Included in this are the errors inherent in the computer, errors due to baseline drift, errors in the injection of dye and acutal variation of cardiac output over a series of successive determinations. The size of this error is comparable to that involved in manual calculation. The mean value of five successive curves will be within 10% of the real value in 99 cases out of 100. Advances in methodology and equipment are discussed which make calibration simpler and more accurate, and which should also improve the quality of computer determination. A list of suggestions is given to minimize the errors involved in the clinical use of this equipment.  (+info)

Computer-controlled automation of radioimmunoassay based on gel entrapment of antibody. (3/44)

We describe a new, broadly applicable approach to radioimmunoassay. Solid-phase binding reagent is prepared by entrapping antibody in polyacrylamide gel. This gel is then fragmented, sieved, and dehydrated in 95 percent ethanol. Upon evaporation of the ethanol, the dry antibody-gel particles are dispensed into miniature disposable plastic columns. A unidirectional flowing stream configuration is used to construct a standard curve for the polypeptide hormone, angiotensin I, used here to exemplify the technique. Good reproducibility of this standard curve is demonstrated. The analytical system includes a computer-controlled sample turntable, digital pipet, and liquid-switching assembly.  (+info)

On-line identification of sensory systems using pseudorandom binary noise perturbations. (4/44)

A technique of on-line identification of linear system characteristics from sensory systems with spike train or analog voltage outputs was developed and applied to the semicircular canal. A pseudorandom binary white noise input was cross-correlated with the system's output to produce estimates of linear system unit impulse responses (UIRs), which were then corrected for response errors of the input transducers. The effects of variability in the system response characteristics and sensitivity were studied by employing the technique with known linear analog circuits. First-order unit afferent responses from the guitarfish horizontal semicircular canal were cross-correlated with white noise rotational acceleration inputs to produce non-parametric UIR models. In addition, the UIRs were fitted by nonlinear regression to truncated exponential series to produce parametric models in the form of low-order linear system equations. The experimental responses to the white noise input were then compared with those predicted from the UIR models linear convolution, and the differences were expressed as a percent mean-square-error (%MSE). The average difference found from a population of 62 semicircular canal afferents was relatively low mean and standard deviation of 10.2 +/- 5.9 SD%MSE, respectively. This suggests that relatively accurate inferences can be made concerning the physiology of the semicircular canal from the linear characteristics of afferent responses.  (+info)

Coagulation-time determination with automatic multivariable analysis, by use of a miniature centrifugal fast analyzer. (5/44)

Use of a miniature Centrifugal Fast Analyzer for the parallel photometric monitoring of the coagulation process is shown to have a number of advantages. These include a choice of optical modes, virtually simultaneous initiation and observation of the coagulation process for a number of patient-plasma samples and an on-board control sample, small sample and reagent volume requirements, and automatic determination of a number of diagnostically useful variables (including relative fibrinogen content) from the data recorded in a single run. Also, the system is shown to give results that correlate well with those obtained by conventional techniques for determination of prothrombin time.  (+info)

Influence of an aggregated multienzyme system on transient time: kinetic evidence for compartmentation by an aromatic-amino-acid synthesizing complex of Neurospora crassa. (6/44)

The aromatic complex of Neurospora crassa is an aggregated multienzyme system which catalyzes five consecutive reactions in the central pathway leading to the biosynthesis of the aromatic amino acids. In an attempt to understand the physiological importance of this complex in particular, as well as the importance of cellular organization of enzyme systems in general, we have isolated the complex and have begun to characterize its catalytic properties. Optimum conditions for the assay of the overall 5-step reaction catalyzed by the partially purified complex have been determined. An analog computer was programmed to represent an unaggregated system of five enzymes with rate constants identical to those found for the constituent enzymes of the complex. By direct comparison, it was shown that the lags (transient times) obtained for the overall reaction were 10-15 times longer for the hypothetical unaggregated system than for the complex. We conclude from these data that the aggregated multienzyme system compartmentalizes intermediate substrates during the course of the overall reaction. We suggest that, in addition to "channeling" intermediates of competing pathways, reduction of the transient time may be an important consequence of the containment of intermediates within a physically associated enzyme sequence. The fact that the aromatic complex exhibits a second catalytic property unique to aggregated enzyme systems, "coordinate activation" [Welch, G.R. & Gaertner, F.H. (1975) Arch. Biochem. Biophys., in press] indicates that the physical association of these enzymes may have more than one physiological function.  (+info)

The dissociation of flavin coenzymes from trypsin-solubilized NADPH/Cytochrome c (P-450) reductase of pig-liver microsomes. (7/44)

The change in fluorescence emission at 520 nm after excitation at 365 nm was used to investigate the effect of pH and ionic strength on the dissociation of flavin cofactors from microsomal NADPH/cytochrome c (P-450) reductase. In the unmodified enzyme both the FAD and FMN moieties appeared to dissociate at a similar rate and followed first-order kinetics. The rate constant for the dissociation was increased by low pH and high ionic strength, particularly in the range pH 4.4-3.8 (0.02 M acetate buffer) where the rate constants increased 80-fold. Modification of the enzyme by treatment with p-chloromercuribenzoate enhanced the rate of flavin dissociation and, in the region of pH 4, resulted in a biphasic increase in fluorescence consistent with two simultaneous parallel first-order dissociations. It was concluded that p-chloromercuribenzoate treatment modified the protein so that the two flavin cofactors dissociated at different rates. Using the measured rate constants for the dissociations, and the known variation in fluorescence of flavin nucleotides with pH, an analogue computer simulation of the dissociation as well as a manual curve-fitting procedure showed that the biphasic response could be explained as a simultaneous rapid dissociation of FAD and a slower loss of FMN from the protein.  (+info)


The solutions, n(t), of the differential equation dn/dt = alpha (1 - n) n (4 - 6n + 4n(2) - n(3)) - betan(2) (4 - 6n + 4n(2) - n(3)) in which alpha and beta are instantaneous functions of membrane potential, are shown to fit with good accuracy the time courses of the rise of potassium conductance during depolarizing steps in clamp potential, found experimentally by Hodgkin and Huxley and by Cole and Moore. The equation is derived by analysing the dynamic behaviour of a system consisting of a square array of interacting pores. The possible role of Ca(++) ions in this system is discussed.  (+info)

While a wide variety of mechanisms have been developed throughout history, some stand out because of their theoretical importance, or because they were manufactured in significant quantities. Most practical mechanical analog computers of any significant complexity used rotating shafts to carry variables from one mechanism to another. Cables and pulleys were used in a Fourier synthesizer, a tide-predicting machine, which summed the individual harmonic components. Another category, not nearly as well known, used rotating shafts only for input and output, with precision racks and pinions. The racks were connected to linkages that performed the computation. At least one US Naval sonar fire control computer of the later 1950s, made by Librascope, was of this type, as was the principal computer in the Mk. 56 Gun Fire Control System. Online, there is a remarkably clear illustrated reference (OP 1140) that describes[28] the fire control computer mechanisms. For adding and subtracting, precision ...
The usefulness of a digitally controlled analog computer in studying digital detection systems was examined. A program was developed for a computer equipped with parallel logic elements. Experience with the system shows it to be a very useful tool for such studies particularly because of the excellent man machine interaction and also because of a possible cost advantage.

Once transcription is complete, there are further controls that allow the network of enzymes and genes to control itself. Im not going to list all of them, but one that cannot be left out involves alternative splicing of RNA. This is a process in which the transcribed RNA is edited, usually removing a number of sections called introns, while creating the final mRNA. Which introns are removed, and sometimes where their boundaries are set, determines the sequence of the final mRNA, and thus the character of the protein. Alternative splicing can be affected by enzymes, but also by non-coding RNAs of various types and provenance, including those snipped out of the introns of other genes. A description of some of the ways in which alternative splicing can be regulated may be found in Regulation of Alternative Splicing: More than Just the ABC by Amy E. House and Kristen W. Lynch. It may turn out that the number of data connections that affect protein (enzyme) concentration via regulation of internal ...
Awesome! I can talk about what I think is one of the coolest inventions of all time: the analog computer.. An analog (more properly, a mechanical) computer was actually the worlds first computer - the Antikythera Mechanism. It was an ancient Greek device that predicted the motions of the planets and other astronomical objects. Only parts of it have been found, but we can figure out a few of its basic properties. It made its computations using an elaborate system of gears.. Fast forward a couple millennia. Lets go to England, and meet a man by the name of Charles Babbage. Im guessing youve heard of him. He shows up in a lot of books on alternative history, because hes hailed as one of the first computer pioneers. Babbages first computer was the Difference Engine, a glorified calculator that could work with polynomials. It used a lot of gears to work with polynomials and do advanced calculations. Babbage got some funding from the government, but not a lot.. Later, he worked on his more ...

In this manner, the neural computer of the invention can be programmed to learn different confirurations as well as different synaptic values.
The kinetics of sodium, movement into human red blood cells has been studied in vivo with 24Na. When human serum albumin-131I is used to measure the percentage of plasma trapped in the packed red blood cells after centrifugation, approximately 30 % of red blood cell sodium is found to equilibrate immediately with plasma. It is concluded that this immediately exchangeable compartment of red blood cell sodium is an experimental artefact, associated with the use of labeled albumin for measuring plasma trapping. This immediately exchangeable fraction disappears when sucrose-14C is used to measure plasma trapping. The experimental results were examined by compartmental analysis, using an analogue computer. The results obtained, when plasma trapping was measured with sucrose-14C could be simulated by the use of models containing two compartments, arranged in series or in parallel. The errors of the techniques used and the possible physical basis for the results are discussed.. ...
DARPA future research includes fascinating new technology like simulating the brain, self-destructing computers, analog computers and more.
I]n a fundamental sense all computing is based on an analogy, that is, on a systematic relationship between the states and processes in the computer and those in the primary system. In a digital computer, the relationship is more abstract and complex than simple proportionality, but even so simple an analog computer as a slide rule goes beyond strict proportion (i.e., distance on the rule is proportional to the logarithm of the number). In both analog and digital computation-indeed in all computation-the relevant abstract mathematical structure of the problem is realized in the physical states and processes of the computer, but the realization may be more or less direct ([refs]). Therefore, despite the etymologies of the terms analog and digital, in modern usage the principal distinction between digital and analog computation is that the former operates on discrete representations in discrete steps, while the later operated on continuous representations by means of continuous processes ...
The authors give the basic principles of an analog device for solving a system of differential equations describing the behavior of a nuclear reactor with respect to time. Systems of this type are difficult to solve, especially when the reactivity varies with time. The proposed device may be used for solving problems involving six groups of delayed neutrons, or may alternatively be programmed for a simplified equation with a single group of delayed neutrons. The proposed computer may be used in studying high-power reactors where the maximum neutron density in the core may reach 10 to the 15th power n/cu cm.*ANALOG COMPUTERS)

Shortly after the publication of Hodgkin and Huxleys equations for the squid giant axon, Richard FitzHugh was working at the Biophysics Laboratory of the National Institutes of Health (NIH) in Bethesda, Maryland. He undertook an analysis of the mathematical properties of their equations. He used the new techniques of nonlinear mechanics which had been developed by Russian mathematicians led by A. A. Andronov. This was before digital computers became easily accessible. John Moore and FitzHugh started by planning how to program an analog computer which could be used to solve the Hodgkin-Huxley equations. The equipment needed included operational amplifiers, function generators, multipliers, and an ink pen plotter. The laboratory purchased the computer, which occupied four floor-to-ceiling relay racks, full of vacuum tubes. These were continually failing, and FitzHugh had to find and replace several tubes a week, requiring some detective work. The heat from all these tubes sometimes overloaded the ...
Much of modern science was known in ancient times. Robots and computers were a reality long before the 1940´s. The early Bronze Age inhabitants of the Levant used computers in stone, the Greeks in the 2nd century BC invented an analogue computer known as the Antikythera mechanism. An ancient Hindu book gives detailed instructions for the construction of an aircraft -ages before the Wright brothers. Where did such knowledge come from?
The earliest known example of a clockwork mechanism is the Antikythera mechanism, a first-century BC geared analogue computer, somewhat astrolabe-like, for calculating astronomical positions and eclipses, recovered from a Greek shipwreck. There are many other accounts of clockwork devices in ancient Greece, even in its mythology, and the mechanism itself is sophisticated enough to indicate a significant history of lesser devices leading up to its creation.[6]. At some point, this level of sophistication in clockwork technology was lost or forgotten in Europe, and only returned when brought from the Islamic world after the Crusades, along with other knowledge leading to the Renaissance. Clockwork finally recovered the equivalent of pre-Roman technological levels in the 14th century.[7]. As in Greek mythology, there are ambitious automation claims in the legends of other cultures. For example, in Jewish legend, Solomon used his wisdom to design a throne with mechanical animals which hailed him as ...

This Mechanism is considered the worlds fist analogue computer. It was discovered when sponge divers, in Antikythera, dove in off the coast in 1900AD and found this in ocean.. This archeological find dates back to the 2nd century BC, making it well over 2,000 years old and it is a complex system of gears, dials and cogs with amazing precision. Scientist agree that it represents something that would not be seen again until the rise of clocks thousands of years later.. Many speculate that it was used as an astronomy calculator that predicted and measured the cycle of planets in relation to the Sun, Earth, and Moon.. This mechanism has been x-rayed, studies, and attempts have been made to reconstruct it, however its very existence still seems to baffle the minds of scientists today.. What is coincidental is the fact that off the coast of Crete there is a unique historical record of ancient robots of immense size. Furthermore there is a story in Crete of a robot named Talos, who hurled boulders ...

Use clear plastic over the water ends.. you should be able to hot glue it then remove after. Test to make sure your barrier is water tight. The resin has a nasty habit of finding any hole and leaking. You always get an ellipsis where the water effects dries against a barrier.

I have used many resins for this, and my favorite is enviro-tex lite. Also, you can remove any air bubbles with a hairdryer. Just make sure you dont heat the terrain up enough to melt your board grass. I would also pour the water in stages (inch or so at a time) and during a time you can keep an eye on it to get bubbles out. Bubbles have a way of creeping back in after the initial heat removal.

When using the safety factor approach, confidence intervals are not given and the degree of protection is usually unknown. Because of the somewhat arbitrary nature of safety factors, their application must be appropriate to the particular purpose and documentation describing the logic used in selecting a particular number should always be provided. The use of the same safety factor (e.g., 10) in all cases has been discouraged by several regulatory and scientific bodies in favor of case-specific values. In particular, the scale, frequency, severity, and potential for long-term consequences of the environmental insult must be taken into account. Providing protection against an acute spill that is easily remediated may require less precaution (and therefore smaller safety factors) than the permitted continual release of a pollutant discharge. The decision to use a safety factor approach, and the eventual selection of the appropriate number, is more a management decision than a scientific ...
