An investigation of the loads on the vertical tail of a jet-bomber airplane resulting from flight through rough air (1956)

Vertical-tail loads were measured in turbulent air on a four-engine jet bomber. Results showed large load oscillations which were lightly damped. Comparison of experimental results with discrete-load calculations indicated that discrete-gust calculations underestimated the loads by 30 to 40 percent and gave no indication of the low damping. Power spectral analysis, on the other hand, indicated the general frequency characteristics and gave a somewhat better estimate of the peak-load distributions. The present results strongly suggest that discrete-gust calculation for gust loads on vertical tails may seriously underestimate the gust loads for airplanes having lightly damped lateral oscillations.
Evaluating postoperative fever: a focused approach. (2006)

Postoperative fever should be evaluated with a focused approach rather than in "shotgun" fashion. Most fevers that develop within the first 48 hours after surgery are benign and self-limiting. However, it is critical that physicians who provide postoperative care be able to recognize the minority of fevers that demand immediate attention, based on the patient's history, a targeted physical examination, and further studies if appropriate. Fever that develops after the first 2 days following surgery is more likely to have an infectious cause, but noninfectious causes that require further evaluation and treatment must also be considered. When evaluating postoperative fever, a helpful mnemonic is the "four Ws": wind (pulmonary causes: pneumonia, aspiration, and pulmonary embolism, but not atelectasis), water (urinary tract infection), wound (surgical site infection), "what did we do?" (iatrogenic causes: drug fever, blood product reaction, infections related to intravenous lines).
Surface Structures and Stability of Arsenic(III) on Goethite:  Spectroscopic Evidence for Inner-Sphere Complexes (1998)

The adsorption and stability of arsenite [As(III)] on goethite (α-FeOOH) was investigated using a combination of standard batch techniques and X-ray absorption spectroscopy (XAS). The reactivity of As(III) with α-FeOOH at varying pH and As(III) concentration provided macroscopic evidence for strong complexation on the α-FeOOH surface. Extended X-ray absorption fine structure (EXAFS) spectroscopy gave an average As(III)−Fe interatomic distance of 3.378 ± 0.014 Å, which is indicative of bidentate binuclear bridging As(III) complexes on the α-FeOOH surface and which is similar to other oxyanions which adsorb on α-FeOOH by an inner-sphere mechanism. X-ray absorption near-edge structure (XANES) analysis indicated that the As(III)−α-FeOOH surface complex is stable toward heterogeneous oxidation to As(V), as determined by the energy position of the X-ray absorption edge. The structural information from EXAFS was included in the description of As(III) adsorption on the α-FeOOH surface using a surface complexation model (the constant capacitance model). These results suggest that As(III) surface complex formation on iron(III) oxides may play an important role in the environmental behavior of arsenic.
Wavelet based pulse rate and Blood pressure estimation system from ECG and PPG signals (2011)

Conventional blood pressure meters are based on cuff and are considered being inconvenient for daily monitoring and these are very sensitive to artifacts due to the presence of cuff. By having a cuff, the efficiency of the device will be reduced in terms of power consumption, restriction of frequency and also ease of use. This paper aimed at designing a noninvasive cuff-less blood pressure and pulse rate estimation system based on pulse transit time (PTT) technique using wavelets. This paper presents a novel algorithm and its real time implementation details for denoising ECG and PPG signals which are highly non stationary signals and finding out pulse rate and PTT using discrete wavelet transform (DWT) in MATLAB and LabVIEW. Hence two important parameters of cardiology i.e. Pulse rate and Blood pressure can be easily measured at a time from ECG and PPG signals that can continuously monitor the health of an individual with a cardiac disorder.

A review on raw materials, commercial production and properties of lyocell fiber (2020)

As one of the regenerated cellulosic fibers, viscose fiber has the largest output. However, the wastes produced in the manufacturing process are difficult to eliminate, which restricts the development of viscose fiber. Lyocell fiber is claimed as “green and eco-friendly fiber” with a good application prospect in the 21st century. The preparation of lyocell fiber is based on the cellulosic non-derivative solution system, i.e., N-methylmorpholine-N-oxide system which is nontoxic and recyclable. In this review, firstly, the demands of dissolving pulp properties for regenerated-cellulosic fiber (RCF), especially for lyocell fiber, were introduced in detail. Next, the whole manufacturing processes including pretreatment, preparation of spinning dope, spinning, posttreatment and efficient solvent recovery technologies were reviewed emphatically. Then, the properties and structural characteristics of lyocell fiber were illustrated. At last, some suggestions were proposed for lyocell fiber development in China.
History of the Methamphetamine Problem (2000)

Methamphetamine, called meth, crystal, or speed, is a central nervous system stimulant that can be injected, smoked, snorted, or ingested orally; prolonged use at high levels results in dependence. Methamphetamine (MA) is a derivative of amphetamine, which was widely prescribed in the 1950s and 1960s as a medication for depression and obesity, reaching a peak of 31 million prescriptions in the United States in 1967. Until the late 1980s, illicit use and manufacture of MA was endemic to California, but the MA user population has recently broadened in nature and in regional distribution, with increased use occurring in midwestern states. An estimated 4.7 million Americans (2.1% of the U.S. population) have tried MA at some time in their lives. Short- and long-term health effects of MA use include stroke, cardiac arrhythmia, stomach cramps, shaking, anxiety, insomnia, paranoia, hallucinations, and structural changes to the brain. Children of MA abusers are at risk of neglect and abuse, and the use of MA by pregnant women can cause growth retardation, premature birth, and developmental disorders in neonates and enduring cognitive deficits in children. MA-related deaths and admissions to hospital emergency rooms are increasing. Although inpatient hospitalization may be indicated to treat severe cases of long-term MA dependence, optimum treatment for MA abusers relies on an intensive outpatient setting with three to five visits per week of comprehensive counseling for at least the first three months. The burgeoning problems of increased MA use must be addressed by adequate treatment programs suitable for a variety of user types.
Development of gel-forming lyophilized formulation with recombinant human thrombin (2014)

The objective of this work was development and evaluation of gel-forming lyophilized formulation with recombinant human thrombin for topical administration. The influence of pH, ionic strength and buffer type on protein stability was evaluated as part of the pre-formulation screening studies. Results indicated an optimal pH from 6.0 to 7.0 and increased stability with increasing content of sodium chloride. The tested buffer types had no significant effect on thrombin stability. For further development, thermosensitive Pluronic® F-127 was employed as a bulking and gelling agent. Physical and mechanical characterization and viscosity measurement confirmed the gel-forming properties of the formulation at the application temperature of 32 °C. Several techniques (addition of well-soluble polyols, different freezing protocols and reconstitution under vacuum) were tested to decrease the reconstitution time. The obtained results revealed that a vacuum in the vial headspace is crucial for acceptable reconstitution. The freeze drying process has no negative impact on recombinant thrombin stability, and this was confirmed by reverse-phase-HPLC, activity assay and optical density measurements.
Simultaneous reduction and surface functionalization of graphene oxide via an ionic liquid for electrochemical sensors (2013)

A facile approach was developed to prepare well-dispersed ionic liquid functionalized graphene composites using 1-butyl-3-methylimidazolium 2-amino-3-mercaptopropionic acid salt ionic liquid as a reducing reagent and functionalization reagent. The resulting material showed excellent electrochemical activity to catechol and hydroquinone.
Comparison of a Multiplex Flow Cytometric Assay with Enzyme-Linked Immunosorbent Assay for Quantitation of Antibodies to Tetanus, Diphtheria, and <i>Haemophilus influenzae</i> Type b (2002)

We developed a multiplexed indirect immunofluorescence assay for antibodies to Haemophilus influenza type b (Hib) polysaccharide and the toxoids of Clostridium tetani (Tet) and Corynebacterium diphtheriae (Dip) based on the Luminex multiple-analyte profiling system. A pooled serum standard was calibrated against World Health Organization standards for Dip and Tet and an international standard for Hib. The multiplexed Luminex assay was compared to individual enzyme-linked immunosorbent assays (ELISAs) for the same analytes. By both methods, 75 (92.6%) of 81 of random serum samples had protective levels of antibody to Tet (> or = 0.1 IU/ml). For Dip, 81.5% of the samples had protective antibody levels (> or = 0.1 IU/ml) by ELISA and 80.2% had protective antibody levels by Luminex. Protective levels (> or = 1.0 microg/ml) of antibody to Hib were found in 45.0% of the samples tested by ELISA and in 39.0% of the samples tested by Luminex. The correlations (R(2)) between ELISA and Luminex of the 81 samples were 0.96, 0.96, and 0.91 for Tet, Dip, and Hib, respectively. There was also similar agreement between Luminex and ELISA for sera collected before and 1 month after Tet, Dip, and Hib vaccine administration. Both methods detected strong postvaccination responses. The Luminex method is an attractive alternative to ELISA since it reduces labor and reagent costs, as well as assay time.

El discernimiento como propuesta pedagógica a la luz del misterio histórico de la encarnación (2014)

This article aims to explore common spaces for dialogue between the disciplines of theology and pedagogy, under the light of a shared core that is discernment. Teachers are required to continually reflect on their pedagogical activities, a task that is facilitated by the practice of discernment. From the perspective of Christian faith, discernment is ultimately based on the Word of God, Jesus Christ, who is embodied and lives among men. This leads us to understand that discernment is not exclusive to theology but a task that is common to both education and religious life, which is why we have elected to present it as a pedagogical proposal
Defect Disorder of Titanium Dioxide (2006)

The present work derived defect disorder diagram representing the effect of oxygen activity on the concentration of both ionic and electronic defects for undoped TiO2. This diagram was determined using the equilibrium constants derived in the present work, including (i) the intrinsic electronic equilibrium constant, (ii) the equilibrium constant for the formation of oxygen vacancies, and (iii) equilibrium constant for the formation of titanium vacancies. These equilibrium constants are consistent with three properties determined independently, including: electrical conductivity, thermoelectric power and change of mass determined by thermogravimetry. The derived defect disorder diagram may be used for tailoring semiconducting properties of TiO2 that are desired for specific applications through the selection of optimized processing conditions.
SPECT Image Quality and Quantification (2006)

Accurate reconstruction methods for SPECT are a pre-requirement for absolute tracer quantification. Exact activity numbers can be extracted from SPECT images by use of iterative reconstruction with appropriate corrections for attenuation, scatter and detector resolution. We have developed an analytical model for SPECT image generation, including attenuation, scatter and reconstruction by filtered back-projection (FBP). Image quality is described in terms of signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR). MatLab simulations were added to include an evaluation of ordered-subset expectation maximization (OSEM) as an example of statistical reconstruction, and for a quantitative assessment of lesion signal recovery. As expected, classical reconstruction without attenuation or scatter correction provides incorrect contrast values, and standard corrections like the Chang method cannot mitigate this problem. Statistical reconstruction allows implementing all corrections and results in better image quality than FBP. Our analysis shows, however, that for adequate signal recovery the contrast-to-noise ratio for OSEM is the same as for FBP. We explain the trade-off between SPECT image quality and quantification by describing reconstruction in terms of signal power spectra (SPS), noise power spectra (NPS) and detective quantum efficiency (DQE).
Preparation of continually graded barriers of YPrBaCuO for HTS Josephson junctions (2001)

We report preparation of a novel barrier structure for high T/sub c/ superconducting multilayer Josephson junctions using a simple composite target technique. Such a barrier consists of Y/sub x/Pr/sub 1-x/Ba/sub 2/Cu/sub 3/O/sub y/ with a continually varied concentration of yttrium. In this barrier no lattice mismatch and other incompatibility problems occur between adjacent layers. Thus the formation of interfacial defects and structural strain can be mostly prevented. The Josephson coupling takes place at the electrically formed interfaces rather than the structural interfaces. A particular feature of these junctions is that the effective thickness of the barrier strongly depends on the measuring temperature and the concentration gradient. The absence of the structural interface in the weak link region greatly enhances the reproducibility and the performance of these junctions.
Studies of shrinkage in photopolymerisable materials for holographic applications (2013)

Holography is now firmly established as a tool for scientific and engineering studies and also as a display medium. Holographic performance mainly depends on the choice of recording wavelengths, recording material, recording conditions and experimental setup as well as environmental conditions in the laboratory. Acrylamide based photopolymer has significant advantages as a holographic recording material such as self-development, low scatter, high diffraction efficiency, ease of preparation and low cost. The main objective of this project is to determine and minimise the shrinkage of an acrylamide based photopolymer developed in the Centre for Industrial and Engineering Optics for holographic recording. This recording material is sensitized in the visible spectrum with Erythrosine B, a green sensitive dye. The shrinkage of the material is determined for different exposure intensities and thicknesses using different techniques in order to determine the optimum conditions for holographic recording. We also have carried out experiments at different spatial frequencies of recording. The influence of nanoparticle dopants on the shrinkage, diffraction efficiency and the dynamic range of the photopolymer system is also studied. The results shows that careful consideration is needed to attain maximum efficiency and minimum shrinkage during holographic recording. Incorporation of zeolite nanoparticles shows improvement in holographic recording characteristics in the photopolymer material. Diffraction efficiency is improved up to 40% and shrinkage is reduced to one half with increased concentration of nanoparticles. Using Electronic Speckle Pattern Interferometry (ESPI) phase shifting technique a 3D map due to shrinkage has been calculated. The shrinkage map has the same circular symmetry as the profile of the recording beam as expected.

The chemical amplification concept was invented at IBM Research and quickly brought into use in the production of dynamic random access memory devices in the company. It has remained as an important foundation for the design of advanced resist systems for use in short-wavelength (<300-nm) lithographic technologies.
Identification of Actinomyces (Corynebacterium) pyogenes with the API 20 Strep system (1988)

A total of 62 strains of Actinomyces pyogenes (previously Corynebacterium pyogenes) were examined by the API 20 Strep system (API System, La Balme Les Grottes, Montalieu-Vercieu, France). The system was shown to be reliable and rapid when the tests were compared with standard identification methods. No confusion occurred with streptococcal profiles in the current API 20 Strep data base.
Optic Fiber Methane Gas Sensor Based on Tunable Diode Laser Absorption Spectroscopy (2010)

Tunable diode laser absorption spectroscopy (TDLAS) is a widely used technique in measuring the concentration of trace gas due to its high sensitivity, high selectivity, and fast time response. The fluctuations of temperature in the gas cell can cause the characteristics of the absorption spectra to change in the TDLAS methane sensing system. The three absorption lines in the R(3) transitions of 2v <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> band of methane at 1653.72 nm have been studied, and the influence of the temperature fluctuations on the spectral absorption coefficient and the amplitude of second harmonic is analyzed. A simple piece of equipment with temperature acquisition devices is developed for measuring methane gas concentration, temperature signals are obtained for eliminating the impact of temperature fluctuations. Using calibration coefficient, the amplitude of second harmonic is transformed into standard signal at reference temperature in order to restrain the influence of temperature fluctuations. The results show that this optic fiber methane gas sensor using tunable diode laser absorption spectroscopy can restrains the influence of temperature fluctuations and improves detection accuracy effectively.

Making the gigabit IPsec VPN architecture secure (2004)

By placing the security processors directly in the data path to secure traffic without the aid of additional outside devices or software, the flow-through security device creates a virtual private network that maximizes network processing unit host offload with minimal system integration effort. A virtual private network uses the Internet protocol security (IPsec) framework to provide confidentiality, data integrity, and end point authentication. These features protect corporate data from being viewed or tampered with while in transit over the Internet. Additionally, the VPN supports data compression, which increases Internet performance between sites. Metropolitan area networks and storage area networks lead the trend toward gigabit Ethernet installations that seek to provide higher speed and better security. The decreasing cost of gigabit devices and their increasing availability in PCs are driving the use of gigabit MAN, while increasing data rates drive the use of gigabit SANs as the bit rate to hard-disk media approaches 1 gigabit per second.
An adaptive security model for mobile agents in wireless networks (2005)

In this paper, we have proposed an adaptive security scheme for denial of service security threats in mobile agent system based on wireless ad hoc network environment. This model is based on a fuzzy feedback controller and allows the ad hoc mobile network user to select the security level and requirement he/she needs. Our model integrates the existing security techniques in providing adaptive security for mobile agents in ad hoc network. The goal of the proposed scheme is to provide a security framework that will detect automatically various attacks and then take appropriate measures to deal with the attack. We have simulated the proposed scheme and conducted experiments for selected denial of service attacks.
