Oxygen affinity of human blood in presence of carbon monoxide (1976)

If carbon monoxide is present in the blood, it is necessary to quantitate its effect on apparent O2 affinity in order to properly compute venous PO2 and P50. Ways of doing this are analyzed theoretically. The classical principles of Haldane and of Roughton and Darling are reviewed and simplified. The method of computation of PO2 in the presence of CO as introduced by Forster is shown to be in considerable error. The source of this error is determined. The error produced if the presence of CO is ignored during the computation of P50 is analyzed.
ENGINEERING CLASSIFICATION AND INDEX PROPERTIES FOR INTACT ROCK (1966)

Abstract : Physical and elastic properties of NX-size rock core from 27 localities were investigated in order to develop an engineering classification system for intact rock, and also to develop index properties related to important physical and engineering characteristics. Thirteen rock types are represented. Laboratory tests were conducted on these rocks as follows: unit weight, Shore scleroscope hardness, Schmidt hammer hardness, abrasion hardness, absorption, sonic-velocity stress-strain under cyclic loading to 5,000 psi, uniaxial stress-strain to failure, and point-load tensile strength. A total of 257 specimens with L/D ratios of 2:1 were tested. Statistical studies were conducted with the IBM 7094 computer to determine correlation and regression relationships for selected pairs of variables. A system of engineering classification is proposed in which rocks are classified on the basis of their strength and modulus properties either obtained directly from laboratory tests, or approximately from index properties recommended herein. Application of the proposed engineering classification system to data obtained by others is shown by individual charts for each of several different rock types. Five charts are presented for estimating the strength or modulus properties for intact rock from the numerical indices obtained by either the Schmidt hammer, the Shore scleroscope, or the sonic pulse velocity, all used in conjunction with the unit weight of the rock.
Comparison of sodium dodecyl sulfate-polyacrylamide gel electrophoresis profiles and antigenic relatedness among outer membrane proteins of 49 Brucella abortus strains (1984)

Outer membrane proteins were solubilized from 49 strains of Brucella abortus by sequential extraction of physically disrupted cells with N-lauroylsarcosinate and a dipolar ionic detergent (Verstreate et al., Infect. Immun. 35:979-989, 1982). The strains tested included standard agglutination test strain 1119, virulent strain 2308, and eight reference strains representing each of the biotypes; the remainder were isolates from cattle in North America with natural infections and included biotypes 1, 2, and 4. Three principal protein groups with apparent molecular weights of 88,000 to 94,000 (group 1), 35,000 to 40,000 (group 2, now established as porins [Douglas et al., Infect. Immun. 44:16-21, 1984]), and 25,000 to 30,000 (group 3) were observed in every strain. Some variability in banding patterns occurred among strains, but intrastrain variation was sufficient to preclude the use of sodium dodecyl sulfate-polyacrylamide gel electrophoresis profiles of outer membrane proteins for differentiating among strains of B. abortus. One antigen ([b]) was shared among the porin proteins, and three others ([c], ([d], and ([ e]) were shared among the group 3 proteins of all of the strains tested, indicating that these relationships are probably species wide. These results suggest that it may be possible to use outer membrane proteins from a representative strain of B. abortus in a vaccine for species-wide immunization.
Non-contact induced thermal disturbance of MR head signals (1997)

In this paper, we reported that signal disturbances of the MR sensors could be induced by fluctuation of the spacing between the MR sensors and the disk surfaces, even without a head/disk contact. Both the experimental and the theoretical results suggest that the temperature rise of the MR sensor will decrease as the head/disk spacing decreases due to the heat transfer through a rotating disk.
Knee arthroplasty: growing trends and future problems (2010)

Total knee arthroplasty, as practiced in the early 21st century, is a product of almost 150 years of understanding the biomechanics of the knee as well as the development of prosthetic materials and surgical techniques, with good long-term results. Patient expectations after total knee arthroplasty have changed; patients undergo total knee arthroplasty hoping to restore their quality of life, which sometimes includes activities requiring high physical demand. Both cemented and uncemented knees provide long-lasting fixation. Minimally invasive surgery limits soft-tissue damage and may facilitate faster rehabilitation. Better materials and implant designs have increased the range of motion and decreased wear. Computer-assisted navigation surgery will render more accurate placement of implants. This article discusses developments in selected topics related to adult knee reconstruction to provide stable and durable implants. Finally, health economics will dictate what is affordable and cost effective in any healthcare system.
Activation of the Complement Cascade by Trypsin (1991)

In twenty-three patients with acute pancreatitis, the plasma levels of immunoreactive trypsin were determined with a RIA method. The patients were divided into groups according to the severity of the disease. Ranson's criteria and the development of multisystem organ failure were used for the classification. Elevated plasma levels of immunoreactive trypsin were found in all groups after admittance. Incubation of fresh human serum and plasma with bovine trypsin in concentrations between 10(-6) and 10(-4) M at 20 degrees C activated the complement cascade. The anaphylatoxins C3a and C5a were determined with a RIA and the terminal complement complex (TCC) with an ELISA method. C3a and C5a were released and TCC was formed. The effect of trypsin on leukocyte activation was determined with a chemiluminescence technique. Trypsin dissolved in saline did not activate the leukocytes. However, serum digested by trypsin-activated leukocytes in a dose-dependent manner. The present study supports the theory that trypsin can activate complement components and results in formation of split products which have potent vascular, and leukocyte activating effects.
Sterilization Abuse (1978)

Sterilization abuse is a condition that affects poor and third-world women who have little or no political power. This paper focuses on the important issues of sterilization abuse through an accounting of the present problem of increasing caes of forced sterilization. The first laws contributing to the legalization of the state to sterilize were passed in 1907. Cases have been tried, committees have been formed and finally guidelines have been set to begin to solve the critical problem of sterilization abuse.

Through long-term research and analysis, we can find that the Internet of things technology analysis method proposed in this paper can effectively provide new development ideas for the research and development of data asset management system based on graph database under the Internet of things technology.
A robust Hough transform algorithm for determining the radiation centers of circular and rectangular fields with subpixel accuracy (2009)

Uncertainty in localizing the radiation field center is among the major components that contribute to the overall positional error and thus must be minimized. In this study, we developed a Hough transform (HT)-based computer algorithm to localize the radiation center of a circular or rectangular field with subpixel accuracy. We found that the HT method detected the centers of the test circular fields with an absolute error of 0.037 +/- 0.019 pixels. On a typical electronic portal imager with 0.5 mm image resolution, this mean detection error was translated to 0.02 mm, which was much finer than the image resolution. It is worth noting that the subpixel accuracy described here does not include experimental uncertainties such as linac mechanical instability or room laser inaccuracy. The HT method was more accurate and more robust to image noise and artifacts than the traditional center-of-mass method. Application of the HT method in Winston-Lutz tests was demonstrated to measure the ball-radiation center alignment with subpixel accuracy. Finally, the method was applied to quantitative evaluation of the radiation center wobble during collimator rotation.
Protein detection using a radio frequency biosensor with amplified gold nanoparticles (2007)

This study presents a device for protein detection using a low-pass radio frequency filter with gold nanoparticles (AuNPs). Self-assembled multilayer gold nanoparticles were immobilized on the sensing surface of the filter by sandwich immunoassay. The measured frequency of the filter ranges from 50MHzto30GHz. The multilayer gold nanoparticles result in a change of 3dB bandwidth of the low-pass filter. Results show that 1ng∕μl of RIgG solution can be detected after triple-layer AuNPs are completely formed. The change in 3dB bandwidth increases with the concentration of target protein. Therefore, this device has potential for protein quantification.
Managing various levels of a large software system (2003)

The orderly management of releasing, maintaining, and enhancing a large software system is described. The software system is used at various locations. A large software system is defined as more than a million lines of high-level code with associated softcopy documentation. The author only discusses the management of the various levels (versions) of the code within the software system. It is assumed that the requirements and functional specifications have been defined and the appropriate administrative actions have occurred. Specifics of the process are given, such as code library levels for software and softcopy documentation from development through testing and release to production. The process handles multiple levels and types of code and documentation from various groups (departments). A single system is used for tracking and releasing code with minimal personnel resource required. The appropriate level of security control is provided. The tracking and pertinent data are stored in one direct-access database. It is concluded that the data integrity provided by this system makes the developer's job easier. The tracking system keeps management informed of the status of system integration and problems as they develop. The total system ensures the orderly release and maintenance of code with minimal risk of contaminated production code.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Flow Injection Analysis in Bioprocess Control (2020)

Flow injection analysis (FIA) is a relatively novel method of chemical analysis which at present is largely restricted to well-defined laboratory analytical applications. This chapter outlines the operating principles of FIA and describes several examples of the application of the method for on-line bioprocess monitoring. An FIA system can be made by physically assembling modules together in a way that suits the chemistry. Its basic building blocks are those of analytical chemistry: sample handling, transport, speciation, and detection. The chapter discusses the individual components that make up an FIA system and how they have been utilized in bioprocess monitoring. Sample handling in relation to FIA can be accomplished automatically by any physical means. Detectors and techniques that have not been used with FIA, which may have significant impact, are multispecies electrodes, x-ray fluorescence, and neutron activation analysis.
Measurements of the fall‐velocity of water ‐drops and raindrops (1941)

This paper presents measurements of the velocities of water‐drops of sizes ranging from one to six mm in diameter, falling in still air from heights of 0.5 meter to 20 meters. A few measurements of raindrop velocities are also reported. The measurements were undertaken to assist in an understanding of the action of rain, both real and artificial, in eroding soil. The drop‐sizes of rains have also been measured and will be reported separately. All of these studies were carried out at the Hydraulic Laboratory of the National Bureau of Standards as a part of the work of the Soil Conservation Service.

Finding frequent items in probabilistic data (2008)

Computing statistical information on probabilistic data has attracted a lot of attention recently, as the data generated from a wide range of data sources are inherently fuzzy or uncertain. In this paper, we study an important statistical query on probabilistic data: finding the frequent items. One straightforward approach to identify the frequent items in a probabilistic data set is to simply compute the expected frequency of an item and decide if it exceeds a certain fraction of the expected size of the whole data set. However, this simple definition misses important information about the internal structure of the probabilistic data and the interplay among all the uncertain entities. Thus, we propose a new definition based on the possible world semantics that has been widely adopted for many query types in uncertain data management, trying to find all the items that are likely to be frequent in a randomly generated possible world. Our approach naturally leads to the study of ranking frequent items based on confidence as well.
Selective Endothelin-A Receptor Antagonism Reduces Proteinuria, Blood Pressure, and Arterial Stiffness in Chronic Proteinuric Kidney Disease (2011)

Proteinuria is associated with adverse cardiovascular and renal outcomes that are not prevented by current treatments. Endothelin 1 promotes the development and progression of chronic kidney disease and associated cardiovascular disease. We, therefore, studied the effects of selective endothelin-A receptor antagonism in proteinuric chronic kidney disease patients, assessing proteinuria, blood pressure (BP), and arterial stiffness, key independent, surrogate markers of chronic kidney disease progression and cardiovascular disease risk. In a randomized, double-blind, 3-way crossover study, 27 subjects on recommended renoprotective treatment received 6 weeks of placebo, 100 mg once daily of sitaxsentan, and 30 mg once daily of nifedipine long acting. Twenty-four-hour proteinuria, protein:creatinine ratio, 24-hour ambulatory BP, and pulse wave velocity (as a measure of arterial stiffness) were measured at baseline and week 6 of each treatment. In 13 subjects, renal blood flow and glomerular filtration rate were assessed at baseline and week 6 of each period. Compared with placebo, sitaxsentan reduced 24-hour proteinuria (-0.56±0.20 g/d; P=0.0069), protein:creatinine ratio (-38±15 mg/mmol; P=0.0102), BP (-3.4±1.2 mm Hg; P=0.0069), and pulse wave velocity (-0.64±0.24 m/s; P=0.0052). Nifedipine matched the BP and pulse wave velocity reductions seen with sitaxsentan but did not reduce proteinuria. Sitaxsentan alone reduced both glomerular filtration rate and filtration fraction. It caused no clinically significant adverse effects. Endothelin-A receptor antagonism may provide additional cardiovascular and renal protection by reducing proteinuria, BP, and arterial stiffness in optimally treated chronic kidney disease subjects. The antiproteinuric effects of sitaxsentan likely relate to changes in BP and renal hemodynamics.
Evolving access networks: a European perspective (1997)

The diversity of telecommunications markets and access network infrastructure among the countries of Europe is a complicating factor in the development of effective standards for Europe's future access networks. The need for evolving access networks to make efficient use of a wide variety of existing infrastructure may at times conflict with the long-term requirement for a stable platform of self-consistent standards which allow future-proof evolution. In light of these constraints, the authors summarize progress made in the European Telecommunications Standards Institute (ETSI) toward standards for future access networks.
Quantum well photoconductors in infrared detector technology (2003)

The paper compares the achievements of quantum well infrared photodetector (QWIP) technology with those of competitive technologies, with the emphasis on the material properties, device structure, and their impact on focal plane array (FPA) performance. Special attention is paid to two competitive technologies, QWIP and HgCdTe, in the long-wavelength IR (LWIR) and very-long-wavelength IR (VLWIR) spectral ranges. Because so far, the dialogue between the QWIP and HgCdTe communities is limited, the paper attempts to settle the main issues of both technologies. Such an approach, however, requires the presentation of fundamental limits to the different types of detectors, which is made at the beginning. To write the paper more clearly for readers, many details are included in the Appendix. In comparative studies both photon and thermal detectors are considered. Emphasis is placed on photon detectors. In this group one may distinguish HgCdTe photodiodes, InSb photodiodes, and doped silicon detectors. The potential performance of different materials as infrared detectors is examined utilizing the α/G ratio, where α is the absorption coefficient and G is the thermal generation rate. It is demonstrated that LWIR QWIP’s cannot compete with HgCdTe photodiodes as single devices, especially at higher operating temperatures (&gt;70 K). This is due to the fundamental limitations associated with intersubband transitions. The advantage of HgCdTe is, however, less distinct at temperatures lower than 50 K due to problems inherent in the HgCdTe material (p-type doping, Shockley–Read recombination, trap-assisted tunneling, surface and interface instabilities). Even though QWIP is a photoconductor, several of its properties, such as high impedance, fast response time, long integration time, and low power consumption, comply well with the requirements imposed on the fabrication of large FPA’s. Due to a high material quality at low temperatures, QWIP has potential advantages over HgCdTe in the area of VLWIR FPA applications in terms of array size, uniformity, yield, and cost of the systems. The performance figures of merit of state-of-the-art QWIP and HgCdTe FPA’s are similar because the main limitations come from the readout circuits. Performance is, however, achieved with very different integration times. The choice of the best technology is therefore driven by the specific needs of a system. In the case of readout-limited detectors a low photoconductive gain increases the signal-to-noise ratio and a QWIP FPA can have a better noise equivalent difference temperature than an HgCdTe FPA with a charge well of similar size. Both HgCdTe photodiodes and QWIP’s offer multicolor capability in the MWIR and LWIR range. Powerful possibilities offered by QWIP technology are associated with VLWIR FPA applications and with multicolor detection. The intrinsic advantage of QWIP’s in this niche is due to the relative ease of growing multicolor structures with a very low defect density.
