Stable isotope ratiometer-multiple ion detector unit for quantitative and qualitative stable isotope studies by gas chromatography-mass spectrometry. (2/11)

We have designed and constructed a stable isotope ratiometer-multiple ion detector unit, which can drive existing chromatograph-quadrupole or magnetic sector mass gas spectrometers to monitor up to six ions in turn. Each of the three pairs of ions can be selected for quantitation; thus three different or successive components can be analyzed in a single gas-chromatographic run. A background subtraction option permits the ion intensity in the absence of sample to be subtracted automatically during sample measurement. Displays of accumulated counts and isotope ratio are updated twice per second during the measurement and can be printed out at is conclusion. All six ions can be monitored in the analog mode by parallel outputs to a multipen recorder. Experience gained in the construction of this prototype indicates that such units could be commercially available for $10 000, or about a third to a sixth of the cost of even an inexpensive computer system.  (+info)


Some factors affecting the usefulness of a linear operator in the analysis of tracer data were evaluated. Application of the operator to a sum of two exponential components resulted in the separation of the rate constants with an accuracy of 10 to 15 per cent if they differed by a factor of at least 2 and the error in the data was about 2 per cent. A factor of 4 was necessary if the error in the data was 6 per cent, and of 6 if the error was 10 per cent. The ratio of amplitudes varied from near unity to equality with the ratio of rate constants. However, if the ratio of amplitudes was greater than the ratio of rate constants the method would not resolve the rate constants. Application of the operator to a sum of three exponential components was also considered.  (+info)

Nonlinear cable equations for axons. II. Computations and experiments with external current electrodes. (6/11)

We have investigated the steady-state potential and current distributions resulting from current injection into a close-fitting channel into which a squid axon is placed. Hybrid computer solutions of the cable equations, using the Hodgkin-Huxley equations to give the membrane current density, were in good agreement with experimental observations. A much better fit was obtained when the Hodgkin-Huxley leakage conductance was reduced fivefold.  (+info)

Ribosomal precursors and ribonucleic acid synthesis in Escherichia coli. (7/11)

Ribosomes and immature ribonucleoprotein particles were isolated from extracts of log-phase cells grown under various conditions. Quantitative measurements were made to determine the relative amounts of immature particles present in the extracts. The results indicate that the steady-state level of ribosomal precursors accounted for essentially a constant fraction of the total ribonucleic acid (RNA) of the cells. For cells with RNA-protein ratios between 0.43 and 0.65, about 1.6% of the total RNA occurred as immature ribonucleoprotein particles. Further, increased levels of immature particles were shown to be correlated with a reduced rate of RNA synthesis in cells recovering from chloramphenicol inhibition. The reduction was found to vary directly with the duration of pretreatment in chloramphenicol and, consequently, with the level of immature particles present in the cells.  (+info)

We study the conditions under which discontinuous mechanical properties of a collapsible tube can induce transcritical flows, i.e. the transition through the critical state where the speed index (analogous to the Mach or the Froude numbers for compressible and free surface flows, respectively) is one. Such a critical transition may strongly modify the flow properties, cause a significant reduction in the crosssectional area of the tube, and limit the flow. General relationships are obtained for a short segment using a one-dimensional model under steady flow conditions. Marginal curves delimiting the transcritical regions are identified in terms of the speed index and the cross-sectional area ratio. Since there are many examples of such flows in physiology and medicine, we also analyse the specific case of prosthesis (graft or stent) implantation in blood vessels. We then compute transcritical conditions for the case of stiffness and reference area variations, considering a collapsible tube ...
Using an axisymmetric geometry that retains certain qualitative features of the trachea, we extend one-dimensional modeling of flow in collapsible tubes to include both curved shell effects and, for untethered tubes, wall inertia. A systematic scaling of the finite deformation membrane equations leads to an approximate set which is consistent with the one-dimensional fluid model; axial and normal wall variables are coupled elastically, but only axial inertia is retained. Transverse curvature causes elastic coupling that can give rise to axial wall motion and a flutter instability. The source of instability is the product of a nonzero reference axial curvature with axial tension variation due to axial stretching. The numerical results suggest that this mechanism may be significant even in processes which cannot be assumed one-dimensional.. ...

At least 26 days before ABP-700 dosing, dogs were anesthetized with propofol and isoflurane and surgically instrumented for telemetric monitoring of electroencephalography and electromyography, intraarterial blood pressure, heart rate, body temperature, and physical activity generally as previously described.21 Sterile transmitters (D70-EEE and M10; ...
An X-ray detector has a plurality of detector units and a pair of support members. Each detector unit has a base plate, a detector element secured to the base plate, and a retaining plate supporting the detector element. The base plate has a signal line and a ground line for delivering an electrical signal from the detector element. The retaining plate is positioned parallel to the detector element. The support members are set apart and extend along an arc the center of which is an X-ray source. Each support member has a plurality of slits (grooves) cut in the face facing the other support member and juxtaposed at predetermined intervals along said arc. The end portions of each retaining plate are fitted in one slit of one of the support members and the corresponding slit of the other support member, respectively. Therefore, the detector units are supported by the support members and the detector elements are juxtaposed along said arc and set parallel to the X-ray beams from the X-ray source.

Thus, the present invention provides an everting tube structure of simple construction, which can be easily produced, which allows easy and/or self-administration, and which has an enhanced self-guiding ability.
In a confocal laser scanning microscope with an illuminating configuration ( 2 ), which provides an illuminating beam for illuminating a specimen region ( 23 ), with a scanning configuration ( 3, 4 ), which guides the illuminating beam over the specimen while scanning, and with a detector configuration ( 5 ), which via the scanning configuration ( 3, 4 ) images the illuminated specimen region ( 23 ) by means of a confocal aperture ( 26 ) on to at least one detector unit ( 28 ), it is provided that the illuminating configuration ( 2 ) of the scanning configuration ( 3, 4 ) provides a line-shaped illuminating beam, that the scanning configuration ( 3, 4 ) guides the line-shaped illuminating beam over the specimen f while scanning and that the confocal aperture is designed as a slit aperture ( 26 ) or as a slit-shaped region ( 28, 48 ) of the detector unit ( 28 ) acting as a confocal aperture.
A summed TOFMS having a filter for identifying detector outputs that are likely the result of noise rather than ions striking the ion detector. The TOFMS stores a plurality of data values at locations specified by a register that counts clock pulses. The filter receives the ion measurements from the ion detector and generates an output measurement value corresponding to each ion measurement. The filter sets the output measurement value to a predetermined baseline value if the filter determines that the ion measurement is noise, otherwise the filter sets the output measurement value to the ion measurement. An adder, responsive to the clock signal, forms the sum of the data value specified by the register value and the output measurement value and stores the sum in the memory at the location corresponding to the register value.
The amount of each substance in the blood can be measured in several ways: for example, millimoles (mmol), micromols (μmol) or grams per litre of blood (g/L). The numbers in the table show the range of the normal levels of various substances in the blood of a healthy person. Every lab has different normal values for serum creatinine because their autoanalyzers are different. Every lab also has the option of providing male and female ranges because they do differ based on muscle mass. The values shown above were taken from a Canadian reference lab at the time this content was developed.. ...
Methods : At weaning, rats were divided into two groups and fed either a VA-marginal diet (control group, CN) with normal levels of iron (37 ppm) or the same diet with reduced iron (5 ppm, iron deficient group, ID-). After 5 weeks, n=4 rats from each group were euthanized for baseline measurements, and the remaining rats (n=6 CN, n=10 ID-) received an i.v. dose of 3H-labeled retinol in an emulsion as tracer to initiate the kinetic study. On day 21 after dosing, half of the ID- rats were switched to the CN diet, thus creating an iron repletion group (ID+). Serial blood samples were collected from each rat at 34 preselected time points after dosing. On day 92, all rats were euthanized. Iron and VA status were determined, and model-based compartmental analysis was applied to the plasma tracer data to develop VA kinetic models for rats from all groups.. ...

In the past two decades the widespread use of disease modifying drugs with moderate to strong efficacy has changed the natural course of multiple sclerosis (MS). Health care professionals, researchers, patient organizations and health authorities are in need of recent information about the objectified and subjective long-term clinical outcomes in MS patients. Such information is scarce. We started a prospective, web-based, patient-centred, interactive study of long-term disabilities, disabilities perception and health-related quality of life (HRQoL) in MS patients in The Netherlands (Dutch Multiple Sclerosis Study). The study has an on online patient-driven inclusion and online acquisition of patient-reported outcomes (PROs). At six-months intervals participants complete the Multiple Sclerosis Impact Profile (MSIP) (disabilities and disabilities perception in seven domains and four symptoms), the Multiple Sclerosis Quality of Life-54 items (MSQoL-54), the Modified Fatigue Impact Scale-5 items (MFIS-5)
We have developed a position response calibration method for a micro-channel plate (MCP) detector with a delay-line anode position readout scheme. Using an {\em in situ} calibration mask, an accuracy of 8~$\mu$m and a resolution of 85~$\mu$m (FWHM) have been achieved for MeV-scale $\alpha$ particles and ions with energies of $\sim$10~keV. For high statistics experiments, this method can be directly employed with the experimental data without any dedicated calibration runs. The improved performance of the MCP detector can find applications in many fields of AMO and nuclear physics. In our case, it helps reducing systematic uncertainties in a high-precision nuclear $\beta$-decay experiment.

The upper airway evolved anatomically in humans to subserve several important functions including swallowing, breathing, and vocalization.1 The multifunctionality of the upper airway increases the risk of certain diseases (e.g., aspiration and sleep apnea).2 These functions require that different segments of the airway have differing properties. The trachea receives some support by the tracheal rings, the nasal airway is surrounded by rigid structures, and the oral airway has a rigid boney roof, the hard palate. On the other hand, the pharyngeal airway does not have rigid structures supporting it. It is a collapsible tube whose patency is maintained by muscles whose function is affected by arousal state (sleep/wake, and more specifically during sleep, the stage of sleep), the structures around it, and posture. Thus, the pharyngeal airway is divided anatomically and physiologically into the nasopharynx, retropalatal oropharynx, retroglossal oropharynx, and hypopharynx. ...
X-ray detectors made of crystalline silicon have several advantages including low dark currents, fast charge collection and high energy resolution. For high-energy x-rays, however, silicon suffers from its low atomic number, which might result in low detection efficiency, as well as low energy and spatial resolution due to Compton scattering. We have used a monte-carlo model to investigate the feasibility of a detector for pediatric CT with 30 to 40 mm of silicon using x-ray spectra ranging from 80 to 140 kVp. A detection efficiency of 0.74 was found at 80 kVp, provided the noise threshold could be set low. Scattered photons were efficiently blocked by a thin metal shielding between the detector units, and Compton scattering in the detector could be well separated from photo absorption at 80 kVp. Hence, the detector is feasible at low acceleration voltages, which is also suitable for pediatric imaging. We conclude that silicon detectors may be an alternative to other designs for this special ...
An ionization detector unit for use in a smoke detector includes a housing wall enclosing an ionization chamber, the wall having openings for passage of air through the chamber, the frontal surface of the wall that is exposed to an oncoming air flow from a given direction being inclined relative to an intersecting second surface exposed to the flow. The frontal surface is shaped and positioned to deflect the air flow generally toward the second surface, and the second surface is shaped and positioned to deflect the air flow generally toward the frontal surface, the shape and position of the surfaces cooperatively arranged to cause the deflected air flows to converge and form a region of air in the vicinity of the intersection of the surfaces that is at higher pressure and slower velocity than the oncoming air flow. Apertures are provided in the frontal surface of the housing to enable entry of air from the vicinity of the intersection to establish relatively slow, laminar air flow through the chamber,

Each of the models produces relations between tracers as functions of age or MRT against which real- life measurements can be fitted to test the validity of the models. This was done in the case studies that were undertaken during this project.. Field study: Leeukuil. In this granite/gneiss aquifer groundwater occurs in the weathered overburden and the fracture base rock. Two parallel sub-catchments have been studied by sampling from existing pumped boreholes along the two drainage lines. Tritium and CFC both indicate significant quantities of pre-1955 recharge water in the boreholes. Halfway down both sub-catchments, nitrate levels increase due to seepage from manure heaps from the piggery that is located in the catchment. These pollutant waters are indicative of excessive local recharge and higher CFC levels.. The flow pattern resembles that of flow along a surface somewhat below the water table to which local seepages are added. The tracer data fit those of the exponential flow model and the ...
Improvements in non-invasive detection methods for glucose and other constituents of interest in a sample have been developed. The apparatus and methods of the invention provide an analog of color perception of human vision, preferably in the near infrared region, replacing spectrophotometers and narrow band sources used in other non-invasive near infrared detection methods. A plurality of detector units are used, each covering a broad and overlapping region of the detected spectrum, paralleling color perception and colorimetry. The improvements are primarily concerned with improving the signal-to-background (or noise) ratio such that the data stream is improved. These improvements use congruent sampling, comparison of different data streams from different sample portions or filter sets, using an interrogation system with sufficient speed to allow testing of arterial blood, and using a filter with a spectral structure. In some circumstances, a neural net is used for analysis, allowing the system to
TY - JOUR. T1 - Energy-sensitive cryogenic detectors for high-mass biomolecule mass spectrometry. AU - Frank, Matthias. AU - Labov, Simon E.. AU - Westmacott, Garrett. AU - Benner, W. Henry. PY - 1999/5/1. Y1 - 1999/5/1. N2 - Energy-sensitive calorimetric detectors that operate at low temperatures (cryogenic detectors) have recently been applied for the first time as ion detectors in time-of-flight mass spectrometry. Compared to conventional, ionization-based detectors, which rely on secondary electron formation or the charge created in a semiconductor, cryogenic detectors measure low-energy solid state excitations created by a particle impact. This energy sensitivity of cryogenic detectors results in several potential advantages for TOP-MS. Cryogenic detectors are expected to have near 100% efficiency even for very large, slow-moving molecules, in contrast to microchannel plates whose efficiency drops considerably at large mass. Thus, cryogenic detectors could contribute to extending the mass ...
Graphene is a mono-layer carbon material with low cost, high chemical/thermal stability, and ultrahigh strength and is expected to be a replacement of silicon and noble metals for electron devices, battery materials, photo-/ion detectors and catalysts. Although some of graphene products such as display and electrodes are commercially available, the applications are limited due to the 2D sheet structure. In other words, the performance per gram is excellent but the performance per volume cannot be achieved easily. Therefore, many efforts have been made to construct the 2D material as a 3D structure with retained physical/chemical properties and high volumetric performance. However, the reported 3D nanoporous carbon materials suffer from poor mobility because of the lower crystallinity, which cannot be used for the electron devices. To achieve semiconductor-grade 3D carbon materials, the monolayer graphene sheet with a high crystalline structure is required in a 3D structure. Thus, we have ...

Geochemical tracer data (i.e., 222Rn and four naturally occurring Ra isotopes), electromagnetic (EM) seepage meter results, and high-resolution, stationary electrical resistivity images were used to examine the bi-directional (i.e., submarine groundwater discharge and recharge) exchange of a coastal aquifer with seawater. Our study site for these experiments was Lynch Cove, the terminus of Hood Canal, WA, where fjord-like conditions dramatically limit water column circulation that can lead to recurring summer-time hypoxic events. In such a system a precise nutrient budget may be particularly sensitive to groundwater-derived nutrient loading. Shore-perpendicular time-series subsurface resistivity profiles show clear, decimeter-scale tidal modulation of the coastal aquifer in response to large, regional hydraulic gradients, hydrologically transmissive glacial terrain, and large (4-5 m) tidal amplitudes. A 5-day 222Rn time-series shows a strong inverse covariance between 222Rn activities (0.5−29 dpm L-1)
0005] Instead of the CT device, an MRI device which can obtain morphological images without radiation exposure is receiving attention. A PET/MRI device capable of obtaining both PET and MRI images has been under research and development. In particular, there has been developed a PET/MRI device of semiconductor light receiving element type in which all the detector units of the PET device are arranged within the static magnetic field of the MRI, using magnetically insensitive avalanche photodiodes (APDs) or Geiger mode APDs (also referred to as SiPMs) as the light receiving elements, and this PET/MRI device can be applied to those for small animals and for the heads (See the following non-patent and patent documents: Schlyer D et al.

Deformation of neuron structure can induce abnormalities in action potential propagation in nervous system, which is a potential threat from viewpoint of medical science.The effect of geometrical changes and deformation of neuron structure on the propagation of action potential has been studied theoretically. The theoretical model is based on modified cable equation considering spatial changes of the neuron structure, incorporating the different ionic currents components. The results of our analysis reveal that the morphology of the neuron has a significant effect on properties of action potential propagation in the neuron. We have shown that alteration of the velocity of propagation, and the broadening of action potential pulses directly correspond to the changes in the morphology of neuron fiber. The rates of changes in the above mentioned electrophysiological parameters accord with the rate and type of shape deformation ...
An ECG or EKG may allow you to see your patients heart activity, but it provides only a glimpse of a bigger picture. Because abnormal heart rhythms and cardiac symptoms come and go throughout the day, a singular test wont always show everything that is happening. In order to get the bigger picture, patients need to be recorded throughout an entire day. A holter monitor, or external electrocardiographic recording, is a battery-operated portable device that measures and records the hearts activity continuously for 24 hours. It is essentially a portable ECG that allows you to watch a patients heart rate in real time as he or she moves through the day. It has wires with small electrodes that attach to the skin, so it offers a non-invasive test that can yield insightful results.. With each test you run, your practice will earn $125 in reimbursement. The disposable parts cost just $6 for each test, so you still keep a significant profit. Each individual test takes 3 minutes to hook up to the ...

ABSTRACTVolatile organic compounds (VOCs) emitted from smoldering mosquito coils containing various atomic hydrogen/carbon (H/C) ratios in different relative humidity were examined. The concentrations of individual VOCs were determined using a preconcentrator-gas chromatography/mass spectrometer (GC/MS) and a flame ion detector (FID). Up to 72 VOCs were found. It is noteworthy that benzene and 1,3-butadiene, human carcinogenic substances, were emitted by all tested mosquito coils during burning. The five types of mosquito coils studied had atomic H/C ratios ranging from 1.23 to 1.57, yielding total VOC emission rates and factors of 7,295.72–14,308.17 µg hr–1 and 3,192.78–6,835.03 µg g–1, respectively. VOC emissions were significantly influenced by the carbon, hydrogen and oxygen contents of coils. According to the analyses of VOC emissions, mosquito coils containing the lowest H/C ratio, a low oxygen content, with suitable additives such as CaCO3 are recommended for
