Multiphase-Multifunctional Ceramic Coatings (2013)

Abstract : This project deals with ceramic coatings deposited by thermal spray and based on La2Zr2O7 (LZO) + toughening phase. The phase that showed promising results in dense ceramics to be scaled up and prepare coatings is the LaAlO3 (LAO). LZO and LAO mixtures in a 70:30 mol% ratio were deposited on SS304 and FeCrAlY substrates. Milling followed by a spray drying process enabled production of 70LZO:30LAO mixture in the form of spherical agglomerates with adequate size distribution and flow properties for feeding into a thermal-spray system. The as-sprayed coating comprises crystalline LZO and partially amorphous LAO. The amorphous phase resulted from the high cooling rate experienced by the molten particles. The coatings were annealed at 1100 deg C for promoting crystallization of the amorphous phase. The elastic modulus and hardness clearly increased after the annealing treatment. However, the fracture toughness tested on the annealed coating showed low values of 1.04 MPa m. Further research is required to mitigate the formation of amorphous LAO by proper control of the quenching conditions. Although the fracture toughness improves moderately as the LaAlO3 fraction increases in dense ceramics, the values are still lower than those considered acceptable.

Determination of Accumulated Structural Loads from S/N Gage Resistance Measurements (1973)

<div class="htmlview paragraph">A new, low cost method to determine the accumulated structural loads in service (not to predict component fatigue life) that requires practically no on-board instrumentation is discussed. This method makes use of S/N fatigue life gages with high-gain mechanical multipliers bonded to a component. Permanent change in gage resistance results from the number of component load cycles and their magnitudes. These resistance change data are then used to reconstruct the load range history. The computer program on this method is listed in the Appendix. Results of laboratory tests conducted to validate the new method and evaluate the behavior of the multipliers over a practical range of operating temperature and strain magnitude and frequency are presented. The component load range distribution estimated by this method is compared to that measured by conventional methods for a vehicle operating on a proving ground route. The paper concludes with an application philosophy of this new method and a discussion of future plans.</div>

An Experimental Study on the Treatment of Aquaculture Wastewater on Wetland (2013)

Aiming at the high pollution load of aquaculture wastewater and the low level of profits,oxidation pond treatment process was proposed.The fertilizer for the experiment was quail dung,and the aquatic creature was eichhornia crassipes.The objective was to study the effect of oxidation pond on aquaculture wastewater treatment and compare the effect on aquaculture wastewater treatment between oxidation pond and natural wetland.After treatment for one week,the results showed that the average removal rates of COD,TN and TP were 61.35%,59.16% and 64.94% respectively by oxidation pond,but the removal rates of COD,TN and TP were 38.46%,62.43% and 66.09% separately by natural wetland.From the comparison between the two treatment,oxidation pond had better removal rate of COD,but the two treatments had similar removal rates of TN and TN.
Cardiac energetics during ischaemia and the rationale for metabolic interventions. (2001)

Cardiac work is supported by high rates of combustion of carbon fuel and oxygen consumption. Fatty acids are the main fuel for the healthy heart, supplying approximately 60-80% of the energy. The balance of the energy comes from the oxidation of glucose and lactate. ATP is broken down to fuel contractile work. ATP is resynthesized in the mitochondria using energy from the oxidation of fatty acids, glucose, and lactate. Myocardial ischaemia dramatically alters fuel metabolism. Ischaemia occurs when the coronary blood flow is insufficient to supply enough oxygen to combust carbon fuels and resynthesize ATP at the normal rate. During partial reductions in coronary blood flow (30-60% of normal) there is a proportional decrease in the rates of oxygen consumption and production of ATP, and an increase in uptake of glucose by the heart. However, unlike under normal aerobic conditions, the glucose taken up by the ischaemic myocardium is not readily oxidized in the mitochondria, but rather is converted to lactate and there is a switch from uptake of lactate by the heart to lactate production. This causes a dramatic disruption in cell homeostasis: ATP content decreases; there is accumulation of lactate and H+, a fall in intracellular pH and a decrease in contractile work. Paradoxically, the ischaemic tissue continues to derive most of its energy (50-70%) from the oxidation of fatty acids despite there being a high rate of lactate production. This ischaemia-induced disruption of cardiac metabolism can be minimized by metabolic agents that decrease oxidation of fatty acids and increase the rates of combustion of glucose and lactate, resulting in clinical benefit to the ischaemic patient.
Nutrients and botanicals for erectile dysfunction: examining the evidence. (2004)

Erectile dysfunction affects 50 percent of men ages 40-70 in the United States and is considered an important public health problem by the National Institutes of Health. Consumers are exposed to a plethora of natural products claiming to restore erection and sexual vitality. A review of the available empirical evidence reveals most naturally occurring compounds lack adequate clinical trials to support efficacy. However, arginine, yohimbine, Panax ginseng, Maca, and Ginkgo biloba all have some degree of evidence they may be helpful for erectile dysfunction. Improvements in penile endothelial L-arginine-nitric oxide activity appear to be a unifying explanation for the actions of these naturally occurring agents.
Epoxy Resin Chemistry II (1983)

Elastomer-modified epoxy resins have grown in usage in the past 15 years in several application areas connected with structural adhesives, composites, civil engineering/construction, electrical laminates/encapsulants and corrosion resistance. Some of this increased attention has come about through utility of telechelic butadiene/acrylonitrile liquid polymers. Both carboxyl and amine reactive liquid polymers (CTBN and ATBN) have provided chemistries amenable to this modification with the polybutadiene/acrylonitrile copolymer providing solubility parameters close to if not equaling those of base epoxy resins. It has only been within the last few years that similar elastomer-modified epoxy resins have been examined in epoxy coatings and primers. This chapter reviews a portion of that relatively new journal and patent literature involving epoxy coal-tar, powder, photo-curable and solventless heavy duty coatings as well as metal primers. These examples are employed to illustrate such benefits of elastomer inclusion as reverse impact, bending/crimping, corrosion resistance, thermal shock resistance and coating adhesion. The chapter concludes with an initial reporting on industrial maintenance and marine coatings based on elastomer-modified epoxy resin models. Similar benefits are noted with these traditional solvent-based coatings under ambient cure.
Millimeter-wave technology advances since 1985 and future trends (1991)

The author focuses on finline or E-plane technology. Several examples, including AVES, a 61.5-GHz radar sensor for traffic data acquisition, are included. Monolithic integrated 60- and 94-GHz receiver circuits composed of a mixer and IF amplifier in compatible FET technology on GaAs are presented to show the state of the art in this area. A promising approach to the use of silicon technology for monolithic millimeter-wave integrated circuits, called SIMMWIC, is described as well. As millimeter-wave technology has matured, increased interest has been generated for very specific applications: (1) commercial automotive applications such as intelligent cruise control and enhanced vision have attracted great interest, calling for a low-cost design approach; and (2) an almost classical application of millimeter-wave techniques is the field of radar seekers, e.g. for intelligent ammunitions, calling for high performance under extreme environmental conditions. Two examples fulfilling these requirements are described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Heterophilic interactions of DM-GRASP: GRASP-NgCAM interactions involved in neurite extension. (1996)

DM-GRASP is an immunoglobulin superfamily cell adhesion molecule that is expressed in both the developing nervous and immune system. Specific populations of neurons respond to DM-GRASP substrates appears to require homophilic interactions between DM-GRASP molecules. We were interested in determining whether DM-GRASP interacts heterophilically with other ligands as well. We have found that eleven proteins from embryonic chick brain membranes consistently bind to and elute from a DM-GRASP-Sepharose affinity column. One of these proteins is DM-GRASP itself, consistent with its known homophilic binding. Another protein, at 130 kD, is immunoreactive with monoclonal antibodies to NgCAM. Other neural cell adhesion molecules were not detected in the eluate. The DM-GRASP-Sepharose eluate also contains a potent neurite stimulating activity, which cannot be accounted for by either DM-GRASP or NgCAM. To investigate the interaction of DM-GRASP and NgCAM, antibodies against DM-GRASP were added to neuronal cultures extending neurites on an NgCAM substrate. The presence of antibodies to DM-GRASP decreased neurite extension on laminin, suggesting that the antibody is not toxic or generally inhibiting motility. We present two possible models for the DM-GRASP-NgCAM association and a hypothesis for neural cell adhesion function that features the dimerization of cell adhesion molecules.
Transphoresis and isotachophoresis as preparative techniques with reference to zero-gravity (1974)

Transphoresis and isotachophoresis are high resolution electrophoretic separation methods for biological materials. They benefit substantially from a weightless environment. Low power consumption and apparatus payload per unit product yield reflect their high electrophoretic efficiency. Properties unique to these systems, including their imposition of self-stabilizing geometry, suggest novel apparatus automatically controllable by largely electrical means with few or no moving parts. Configurations allowing continuous and semicontinuous operation, and further improvement of efficiency, are discussed.
Aging studies of Cu-Sn intermetallic compounds in annealed surface mount solder joints (1997)

Our previous investigation (1995), revealed the formation kinetics and characteristics of copper-tin (Cu-Sn) intermetallic compounds (IMC) in leadless ceramic chip carrier (LCCC) surface mount solder joints during infrared (IR)-reflow soldering. The present study focuses on the solid state growth of the interfacial Cu-Sn IMC in LCCC surface mount solder joints under prolonged annealing at elevated temperature. A thick Cu-Sn IMC layer at the Sn-Pb solder/Cu interface of a surface mount solder joint (which can be achieved by prolonged aging at high temperature or after long term operation of surface mount technology (SMT) electronic assemblies) makes the interface more sensitive to stress and may eventually lead to fatigue failure of all SMT solder joint. The microstructural morphology of the Cu-Sn IMC layer at the solder/Cu pad interface in all annealed LCCC surface mount solder joints is duplex and consists of /spl eta/-phase Cu/sub 6/Sn/sub 5/ and /spl epsi/-phase Cu/sub 5/Sn IMC. Both Cu-Sn LMC phases thicken as the aging time increases. On the other hand, at the interface close to the component metallization, the growth of both the /spl eta/- and /spl epsi/-phase were shown to be suppressed, with more a pronounced effect on /spl epsi/-phase, by Ni originating from the metallization. The mean total layer thickness was found to increase linearly with the square root of aging time and the growth was faster for higher annealing temperature. The activation energy for the growth of interfacial Cu-Sn IMC layers and the pre-exponential factor, D/sub 0/, for diffusion were found to be 1.09 eV and 1.68/spl times/10/sup -4/ m/sup 2//s, respectively, for the 0805 LCCC surface mount solder joint using eutectic Sn-Pb solder. The pad size and quantity of Sn-Pb solder employed in LCCC surface mount solder joints were shown to have little effect on the solid state growth rate of interfacial Cu-Sn IMC layers.
The dual method of solving the linear programming problem (1954)

Abstract Many problems in logistics are capable of being formulated as linear programming problems. For example, one such problem is the so‐called transportation problem, which is concerned with obtaining the best way (in the sense of least time, or of least expense, etc.) of shipping stipulated quantities of materials from m origins to n destinations. This paper develops a new computational method of solving general linear programming problems.
An algorithm for the blind identification of N independent signals with 2 sensors (2002)

This paper presents a novel procedure for the blind identification of a linear mixture of n sources with 2 sensors. It is shown that the second characteristic function obeys a partial differential equation (PDE) whose coefficients are directly related to the mixture coefficients. A uniqueness result allows the design of an estimation procedure based on this PDE. An algorithm is therefore proposed and computer experiments illustrate its performance.
Light‐Driven Side‐On Nematic Elastomer Actuators (2003)

A range of monodomain nematic azo side‐on elastomers , containing different proportions of photoisomerizable azo mesogenic moieties, were prepared for the first time photochemically using a radical photoinitiator working at wavelengths above 600 nm. These elastomers exhibit a photomechanical contraction of up to 20 % upon irradiation with UV light. The Figure shows an elastomer film in its contracted form under UV irradiation.
Randomness Requirements for Security (2005)

Security systems today are built on increasingly strong cryptographic
algorithms that foil pattern analysis attempts. However, the security
of these systems is dependent on generating secret quantities for
passwords, cryptographic keys, and similar quantities. The use of
pseudo-random processes to generate secret quantities can result in
pseudo-security. The sophisticated attacker of these security systems
may find it easier to reproduce the environment that produced the
secret quantities, searching the resulting small set of possibilities,
than to locate the quantities in the whole of the number space.
Choosing random quantities to foil a resourceful and motivated
adversary is surprisingly difficult. This document points out many
pitfalls in using traditional pseudo-random number generation
techniques for choosing such quantities. It recommends the use of
truly random hardware techniques and shows that the existing hardware
on many systems can be used for this purpose. It provides suggestions
to ameliorate the problem when a hardware solution is not available.
And it gives examples of how large such quantities need to be for some
particular applications.
Cyclosporin A: a new advance in transplantation. (1982)

Cyclosporin A (CyA)* has been shown to be a cytostatic drug with apparent specificity for the immune system. At clinical trials, an analysis of the patients showed marked immunosuppressive potency of CyA. This selective anti-T cell agent is described in detail, with studies showing the immunological effects of graft survival in renal transplant patients.
Magnetic Cell Sorting Purification of Differentiated Embryonic Stem Cells Stably Expressing Truncated Human CD4 as Surface Marker (2005)

Embryonic stem (ES) cells offer great potential in regenerative medicine and tissue engineering. Clinical applications are still hampered by the lack of protocols for gentle, high-yield isolation of specific cell types for transplantation expressing no immunogenic markers. We describe labeling of stably transfected ES cells expressing a human CD4 molecule lacking its intracellular domain (DeltaCD4) under control of the phosphoglycerate kinase promoter for magnetic cell sorting (MACS). To track the labeled ES cells, we fused DeltaCD4 to an intracellular enhanced green fluorescent protein domain (DeltaCD4EGFP). We showed functionality of the membrane-bound fluorescent fusion protein and its suitability for MACS leading to purities greater than 97%. Likewise, expression of DeltaCD4 yielded up to 98.5% positive cells independently of their differentiation state. Purities were not limited by the initial percentage of DeltaCD4(+) cells, ranging from 0.6%-16%. The viability of MACS-selected cells was demonstrated by reaggregation and de novo formation of embryoid bodies developing all three germ layers. Thus, expression of DeltaCD4 in differentiated ES cells may enable rapid, high-yield purification of a desired cell type for tissue engineering and transplantation studies.
Forecasting tourist arrivals: Google Trends meets mixed-frequency data (2019)

In this article, we examine the usefulness of Google Trends data in predicting monthly tourist arrivals and overnight stays in Prague during the period between January 2010 and December 2016. We offer two contributions. First, we analyze whether Google Trends provides significant forecasting improvements over models without search data. Second, we assess whether a high-frequency variable (weekly Google Trends) is more useful for accurate forecasting than a low-frequency variable (monthly tourist arrivals) using mixed-data sampling (MIDAS). Our results suggest the potential of Google Trends to offer more accurate predictions in the context of tourism: we find that Google Trends information, both 2 months and 1 week ahead of arrivals, is useful for predicting the actual number of tourist arrivals. The MIDAS forecasting model employing weekly Google Trends data outperforms models using monthly Google Trends data and models without Google Trends data.
Organizational quality on the Rey-Osterrieth and Taylor Complex Figure Tests: A new scoring system. (1993)

A new system for measuring organizational quality on the Complex Figure Test (Rey, 1942; Taylor, 1969) is described. This system extends the traditional use of the test as a measure of constructional ability and figural memory. The new system is easy to learn, quick to score, and shows very good interrater reliability. Organizational quality was found to correlate moderately with copy accuracy, half-hour recall, and percentage retained. In an initial application of the system (N = 63), organizational quality of the Rey-Osterrieth Complex Figure successfully discriminated between symptomatic (those with acquired immunodeficiency syndrome [AIDS] or AIDS-related complex [ARC]) and asymptomatic subjects positive for human immunodeficiency virus (HIV), but organizational quality ratings of the Taylor figure did not

Short and long term axotomy-induced ERG changes in albino and pigmented rats. (2009)

Optic nerve injury results in transient reductions of the major ERG components, the a- and b-waves, as well as permanent reductions of the early components of the ERG, the negative and positive scotopic threshold responses. Because ONT induces massive RGC loss, it is likely that permanent reduction in the STR represents a lack of the RGC population, thus highlighting the importance of the STR recordings as an electrophysiological tool for the assessment of RGC function.
