New Phacomp and its Applications to Alloy Design (1984)

New PHACOMP was developed from the calculations of electronic structure of alloys by the DV-Xa cluster method. It is based on the first theoretical approach to the solid solubility problem of alloys, both solute and solvent being transition metals. The electron vacancy number that is an important parameter in the current PHACOMP, is not used any more in the New PHACOMP. Instead, a parameter Md, which is an average energy level of d orbitals of alloying transition metals, was introduced, and used for treating of the phase stability in austenitic (y) alloys. This parameter correlates with electronegativity and atomic size, being parameters used in the classical approach by Hume-Rothery, and Darken and Gurry. The validity of New PHACOMP was proved by examining about 25 ternary phase diagrams. The constant Ed line well represents various phase boundaries such as y/y + CT, y/y + 1-1, y/y + y'(Ni3Al), y/y + D(Ni3Ti) and l//y + b(NiA1) in austenitic alloys. Our method correctly predicts the occurrence of topological close-packed (TCP) phases in practical superalloys. Seve-ral difficulties in the widely used PHACOMP based on the electron vacancy concept, were solved by the present method. New PHACOMP provides a nice tool for better alloy design not only for Ni-base, but also for Co-base and Fe-base superalloys.
A Shrouded Wind Turbine Generating High Output Power with Wind-lens Technology (2010)

We have developed a new wind turbine system that consists of a diffuser shroud with a broad-ring brim at the exit periphery and a wind turbine inside it. The shrouded wind turbine with a brimmed diffuser has demonstrated power augmentation by a factor of about 2–5 compared with a bare wind turbine, for a given turbine diameter and wind speed. This is because a low-pressure region, due to a strong vortex formation behind the broad brim, draws more mass flow to the wind turbine inside the diffuser shroud.
[Assessment of TVOC and odor in the remediation site of contaminated soil and groundwater using electronic nose]. (2013)

According to the conditions of a contaminated soil and groundwater remediation site in Shanghai, the self-built electronic nose was applied to detect VOCs and odor of previously remedied soil and groundwater, remedying soil and groundwater, and the air above and around the site. Combining the formula of TPI and OPI, the value of each point was got and was shown in figures. Results showed: 1. Comparing the determination results of previously remedied with remedying contaminated soil and groundwater, the concentration of TVOC and odor was overall declined. The result was consistent with the fact. The detection result of electronic nose was proved to be right; 2. In the remediation process of soil and groundwater, the volatilization of VOCs and odor was inflected by temperature and works of crushing, adding medicine and turning the soil on time. The concentration showed a trend of overall decline with stage rising, so the electronic noses can be used for dynamic monitoring of the whole remediation process; 3. Combined with the GIS, the electronic noses can preliminary assess space pollution situation caused by the remediation of contaminated soil and groundwater and the influence on the residence in the surrounding region. However, further study on the refined classification of the impact degree is needed.
Federal, state efforts force reexamination of glycol-reboiler emissions (1993)

Regulatory pressures by the U.S. government and several individual states are forcing gas processors to examine their operations for sources of toxic emissions. Of specific concern are emissions from the reboiler still vents of glycol dehydration units. These emissions are being analyzed to determine levels of benzene, toluene, ethyl benzene, and the xylene isomers (BTEX) and other volatile organic compounds (VOC). Concern over BTEX/VOC emissions from these units has been surfacing at industry meetings, such as the recent Gas Processors Association 72nd Annual Convention, and prompted a technical conference on the subject last year sponsored by GRI. Its siting-New Orleans-was intentional: Louisiana has led states' efforts to quantify and control toxic emissions from glycol reboiler stacks. This is the first of three articles which derive from that GRI conference. The paper discusses the regulatory push, efforts in Louisiana, two regulations, other states' efforts, company activities, incinerating vapors, condensing vapors, Rocky Mountain conditions, testing, solutions, and Amoco's experience.
Behavior Profiling and Analysis in Wireless Home Networks (2010)

In this short paper, we present a preliminary design of a behavior profiling system in wireless home network (WHN) for network security monitoring. Figure 1 illustrates a schematic architecture of the behavior profiling system that is deployed in a typical wireless home network. The goals of the proposed behavior profiling system are to i) actively learn the traffic patterns of wireless home networks, ii) detect anomalous behavior from inside networks as well as from the Internet. Based on network traffic patterns for each computer, the system builds baseline behavior profiles, and subsequently detects events of interest through behavior deviations. The contributions of this work are two-fold. First, we propose to build the behavior profiles for each computer in WHNs towards a deep understanding of the traffic patterns in wireless residential networks. Secondly, we present a systematic architecture that aims to detect anomalous behavior through real-time traffic profiling.
Symbian Forensics: An Overview (2008)

This paper aims at unveiling the real and complete structure of the Symbian S60 v3 (third edition) platform filesystem, which is considered one of the most secure and armored systems issued by Symbian Ltd. in the last two years. By analyzing the unique features of security, which have been applied at the filesystem level, it will become clear how to develop applications for digital forensic purposes. Moreover, the limitations and main issues related to accessing the observable portion of the filesystem will be pointed out, and possible solutions will be presented.
The chocolate works (1994)

The employment policies of prominent non-union companies continue to arouse keen interest. Widely regarded as highly sophisticated, they are often seen as leading the way towards a new style of co-operative industrial relations. The practical appeal of these policies stems from a belief in their potential to resolve differences of interest between management and employees. The innovations made by such companies may have provided the blueprint for the practical development of ‘human resource management’ in a growing number of businesses.
Antilipolytic Action of Hesperetin in Rat Adipocytes (1993)

Hesperetin was able to inhibit both epinephrine- and theophylline-induced lipolysis in rat adipocytes. At concentrations of 125 microM and 250 microM, it could augment the inhibitory effect of low insulin concentration (17 microU/2ml) on epinephrine-induced lipolysis. The basal cyclic AMP levels and phosphodiesterase activities in intact adipocytes were unaltered by hesperetin. The antilipolytic action of hesperetin in adenosine deaminase pretreated adipocytes was abolished. Hesperetin could only prevent lipolysis but not reverse the initial lipolytic activity stimulated through the adenosine deaminase pretreatment of the adipocytes. In pertussis or cholera toxin (PT or CT) pretreated adipocytes, the antilipolytic action of hesperetin was unaffected. From the data obtained it is possible to conclude that the antilipolytic action of hesperetin is not mediated through the inhibition of cyclic AMP level nor through CT- or PT-sensitive G proteins. However, the involvement of hesperetin in preventing the accessibility of cellular receptors to the actions of lipolytic agents may be implicated.
Die Konstitution des Xysmalogenins. Glykoside und Aglykone, 205. Mitteilung (1959)

Abstract Xysmalogenin konnte mit CrO 3 in Aceton‐Wasser‐H 2 SO 4 , zu Xysmalogenon (C 23 H 30 O 4 ) oxydiert werden, das in reiner Form isoliert wurde. Durch Kontakt an Al 2 O 3 , liess es sich in ein α,β‐ungesättigtes Keton umlagern, das mit dem bekannten Anhydro‐periplogenon identisch war. Die Doppelbindung im Xysmalogenin liegt daher in 5‐Stellung. Periplogenon wurde erstmals in reiner krist. Form isoliert.

Introduction of Fibre-Reinforced Polymers − Polymers and Composites: Concepts, Properties and Processes (2013)

Introduction of Fibre-Reinforced Polymers − Polymers and Composites: Concepts, Properties and Processes
Measurements of the Fracture Energy of Lithiated Silicon Electrodes of Li-Ion Batteries (2013)

We have measured the fracture energy of lithiated silicon thin-film electrodes as a function of lithium concentration. To this end, we have constructed an electrochemical cell capable of testing multiple thin-film electrodes in parallel. The stress in the electrodes is measured during electrochemical cycling by the substrate curvature technique. The electrodes are disconnected one by one after delithiating to various states of charge, that is, to various concentrations of lithium. The electrodes are then examined by optical microscopy to determine when cracks first form. All of the observed cracks appear brittle in nature. By determining the condition for crack initiation, the fracture energy is calculated using an analysis from fracture mechanics. In the same set of experiments, the fracture energy at a second state of charge (at small concentrations of lithium) is measured by determining the maximum value of the stress during delithiation. The fracture energy was determined to be Γ = 8.5 ± 4.3 J/m(2) at small concentrations of lithium (~Li0.7Si) and have bounds of Γ = 5.4 ± 2.2 J/m(2) to Γ = 6.9 ± 1.9 J/m(2) at larger concentrations of lithium (~Li2.8Si). These values indicate that the fracture energy of lithiated silicon is similar to that of pure silicon and is essentially independent of the concentration of lithium. Thus, lithiated silicon demonstrates a unique ability to flow plastically and fracture in a brittle manner.
Novel Syntheses of Indolizines and Pyrrolo[2,1-<i>a</i>]isoquinolines via Benzotriazole Methodology (1999)

Indolizines and pyrrolo[2,1-a]isoquinolines are synthesized by 1,3-dipolar cycloadditions of pyridinium benzotriazolylmethylides or isoquinolinium benzotriazolylmethylides with ethylenes and acetylenes.
Digital Correlator Speed Improvement by Multiplexing. (1983)

Digital correlators can detect the presence of a reference binary code within a long sequence of bits. Correlation is an essential in proposed spread spectrum applications to future target identification interrogation/reply systems. High rate pseudorandom binary codes can be used to achieve transmission security and resistance to interference and jamming by spreading transmission bandwidth. Digital correlation provides reliability and cost benefits through the use of modern digital integration techniques but has been limited in speed. Several approaches to time division multiplexing of digital correlator devices, whereby k operations are overlapped in time, are developed in this report. Where synchronization with the input signal exists, the resulting multiplexed correlators provide k-times speed improvement over individual correlator devices. A completely synchronized correlator can be formed from k such multiplexed correlators by proper selection of outputs. A simplified realization is presented that only requires one set of k N/k-bit signal and reference registers and k sets of N-bit comparator circuits. Laboratory experimentation and computer simulations to support these concepts are described. (Author)

A freeze-thaw method for disintegration of Escherichia coli cells producing T7 lysozyme used in pBAD expression systems. (2007)

The pLysN plasmid containing the T7 lysozyme gene under control of the lac promoter was constructed to facilitate cell disintegration after expression of recombinant proteins in arabinose-induced expression systems. The usefulness of this plasmid was tested in Escherichia coli TOP10 and E. coli LMG194 cells carrying pBADMHADgeSSB plasmid containing Deinococcus geothermalis SSB protein gene under control of the araBAD promoter. The results showed that low-level expression of T7 lysozyme did not interfere with the target SSB protein production, and that the freezing-thawing treatment was sufficient for disruption of the E. coli cells producing low amounts of T7 lysozyme.
Public-key support for group collaboration (2003)

This paper characterizes the security of group collaboration as being a product not merely of cryptographic algorithms and coding practices, but also of the man-machine process of group creation. We show that traditional security mechanisms do not properly address the needs of a secured collaboration and present a research prototype, called NGC (next generation collaboration), that was designed to meet those needs. NGC distinguishes itself in the care with which the man-machine process was analyzed and shaped to improve the security of the whole process. We include a detailed analysis of the problem of binding a name to a key, traditionally thought to be the province of PKI, but we show that the SDSI local name concept produces a result with superior security to that produced by standard PKI.
Effects of continuous noise backgrounds on rate response of auditory nerve fibers in cat (1984)

This study describes the effects of broadband background noise on the average discharge rate to best-frequency (BF) tones of auditory nerve fibers in the cat. The effects of exposure to long-term continuous noise are compared to the effects of noise gated on and off simultaneously with test tones. Addition of background noise causes a shift of the dynamic portion of tone-evoked rate versus level functions to higher tone intensities. The shift occurs at a mean rate of 0.61 dB of shift for each 1-dB increment in noise level. The rate of shift is independent of best frequency and spontaneous discharge rate. The noise level at which the shift begins is frequency dependent and is consistent with the frequency-dependent bandwidths of auditory nerve fiber tuning curves. The adjustment of the dynamic range shows many similarities to two-tone suppression. Therefore, it is most likely that it is caused by suppression of the response to the BF test tone by energy present in the noise at surrounding frequencies. At high noise levels, the ability of auditory nerve fibers to respond to test tones is limited by the rate response to the noise. As noise level increases, the discharge rate it evokes approaches a fiber's saturation rate and ultimately eliminates the fiber's ability to respond to test tones. Low spontaneous rate fibers, which have been shown to have higher thresholds and wider dynamic range (17,29), are significantly more resistant to saturation by high noise levels. Exposure to broadband noise prior to onset of test tones produces an overall decrement in response rate. This phenomenon is similar to the effects of short-term adaptation (32) and seems to develop independently of the shift of dynamic range. At high noise levels, previous exposure to the noise produces a small dynamic range shift. This effect is similar to that produced by suppression but is smaller. The effect is occluded in continuous noise backgrounds by the adjustment of sensitivity produced by suppression.
A Self-Healing Mechanism for State Machine Based Components. (2006)

Thrombocytopenia in pregnancy carries a major risk of feto-maternal morbidity and mortality. We present a case of hypocellular bone marrow with severe thrombocytopenia with pregnancy induced hypertension (PIH) for emergency lower segment cesarean section (LSCS). This disease is characterized by pancytopenia and hypocellular bone marrow with impaired morphology and maturation. Causes of death due to this disease include hemorrhage and infection secondary to thrombocytopenia and neutropenia especially following surgery. We report successful management of emergency LSCS with severe thrombocytopenia with severe PIH.

Fractal-induced 2D flexible net undulation (2021)

A net immersed in fractal-induced turbulence exhibit a transient time-varying deformation. The anisotropic, inhomogeneous square fractal grid (SFG) generated flow interacts with the flexible net to manifest as visible cross-sectional undulations. We hypothesize that the net's response may provide a surrogate in expressing local turbulent strength. This is analysed as root-mean-squared velocity fluctuations in the net, displaying intensity patterns dependent on the grid conformation and grid-net separation. The net's fluctuation strength is found to increase closer to the turbulator with higher thickness ratio while presenting stronger fluctuations compared to regular-square-grid (RSG) of equivalent blockage-ratio, σ. Our findings demonstrate a novel application where 3D-reconstruction of submerged nets is used to experimentally contrast the turbulence generated by RSG and multilength scale SFGs across the channel cross-section. The net's response shows the unique turbulence developed from SFGs can induce 9 × higher average excitation to a net when compared against RSG of similar σ.
Effects of imatinib and 5-bromotetrandrine on the reversal of multidrug resistance of the K562/A02 cell line (2010)

Research has shown that 5-bromotetrandrine (BrTet) can effectively reverse multidrug resistance (MDR). Imatinib plays an important role in cell proliferation. This study explored the efficacy of the combination of imatinib and BrTet on reversing MDR of tumor cells and its mechanism.Cytoxicity was assessed by MTT assay. Apoptosis of K562/A02 cells was analyzed by flow cytometry. The expressions of mdr1 mRNA and P-glycoprotein (P-gp) were detected using reverse transcription-polymerase chain reaction (RT-PCR) and Western blot analysis.After 48 h of treatment with 0.0625 micromol/L imatinib, 0.5 micromol/L BrTet, or both, the 50% inhibition concentration (IC50) of daunorubicin (DNR) for the K562/A02 cells were 5.69 mg/L, 5.41 mg/L, and 2.19 mg/L, respectively. The gray-scale values of mdr1 mRNA expression in the K562/A02 cells were 0.65+/-0.02, 0.64+/-0.01, and 0.25+/-0.03, respectively. The expression levels of P-gp were 0.74+/-0.02, 0.52+/-0.02, and 0.29+/-0.02, respectively. All decreased significantly in the K562/A02 cells treated with both imatinib and BrTet compared to cells treated with imatinib and BrTet alone (P<0.05). The apoptosis rates of the K562/A02 cells increased without a significant difference after treatment with DNR, imatinib, or BrTet (P>0.05), while increased significantly after treatment with DNR combined with imatinib, BrTet, or both (P<0.05).The MDR of K562/A02 cells may be partially reversed by imatinib or BrTet, and the mechanism may be related to the downregulation of mdr1 mRNA and P-gp expression and the upregulation of the rate of apoptosis in K562/A02 cells. Imatinib combined with BrTet showed a synergistic effect on K562/A02 cells.
A proposed GaAs-based superlattice solar cell structure with high efficiency and high radiation tolerance (1985)

A solar cell structure is proposed which uses a GaAs nipi doping superlattice. An important feature of this structure is that photogenerated minority carriers are very quickly collected in a time shorter than bulk lifetime in the fairly heavily doped n and p layers and these carriers are then transported parallel to the superlattice layers to selective ohmic contacts. Assuming that these already-separated carriers have very long recombination lifetimes, due to their being across an indirect bandgap in real space, it is argued that the proposed structure may exhibit superior radiation tolerance along with reasonably high beginning-of-life efficiency.
