Experiments on the elastoid-inertia oscillations of a rigidly rotating fluid in a cylindrical vessel (1984)

The inertial waves can occur in swirling flows under certain conditions. One of the fundamental phenomena due to the inertial waves is the which is a standing-wave oscillation of a fluid in a rotating cylinder. In the experiment reported here, the elastoid-inertia oscillations of several modes are induced as resonant states by a specially designed apparatus. The patterns of the flow field and resonant frequencies are examined by means of visualization techniques. The experimental results are compared with those of the inviscid linear theory. It is found that both the frequencies and flow patterns of the actual elastoid-inertia oscillations can be well estimated by the linear theory.
A New Class of Asynchronous Rotordynamic Response in High-Speed Rotors (2007)

Virtually all of the nonlinear rotordynamic phenomena studied in the past result in excitation of rotor response at a dominant frequency at or near the critical frequency at rotational speeds other than the critical speed. In experimental work on a “macro-rig” of a micro-rotor in development some years ago at the Gas Turbine Laboratory of MIT, an unforeseen array of asynchronous response frequencies at other than the critical were noted when the rotor was operated at both subcritical and supercritical speeds. However, those responses were not explored in detail at the time. The patterned responses were apparently related to subharmonic and ultra-subharmonic response, but at frequencies lower than the critical frequency. More recently, the author noted a similar pattern of rotordynamic response in the course of operation at subcritical of an experimental turbomachinery component which was experiencing a local rub between the rotor and stator of an interstage seal. Data from that incident revealed a pattern of asynchronous response that had a very similar appearance to the earlier observation. Using a simple numerical model of a rotor employing a single mass mounted on a massless shaft and a piecewise linear (that is, a bilinear) bearing support stiffness to represent the system, it was possible to replicate the response at individual representative points over a range of sub-, trans-, and supercritical high-speed rotor operation. A generalized expression was derived inductively to represent the individual data points. The resultant pattern of data replicated the patterns of data from the two test vehicles which originally inspired the investigation and suggested the means of their suppression where their presence might be undesirable.
Enhanced synthesis and release of dopamine in transgenic mice with gain‐of‐function α6* <scp>nAChR</scp>s (2013)

α6β2* nicotinic acetylcholine receptors (nAChRs)s in the ventral tegmental area to nucleus accumbens (NAc) pathway are implicated in the response to nicotine, and recent work suggests these receptors play a role in the rewarding action of ethanol. Here, we studied mice expressing gain-of-function α6β2* nAChRs (α6L9'S mice) that are hypersensitive to nicotine and endogenous acetylcholine. Evoked extracellular dopamine (DA) levels were enhanced in α6L9'S NAc slices compared to control, non-transgenic (non-Tg) slices. Extracellular DA levels in both non-Tg and α6L9'S slices were further enhanced in the presence of GBR12909, suggesting intact DA transporter function in both mouse strains. Ongoing α6β2* nAChR activation by acetylcholine plays a role in enhancing DA levels, as α-conotoxin MII completely abolished evoked DA release in α6L9'S slices and decreased spontaneous DA release from striatal synaptosomes. In HPLC experiments, α6L9'S NAc tissue contained significantly more DA, 3,4-dihydroxyphenylacetic acid, and homovanillic acid compared to non-Tg NAc tissue. Serotonin (5-HT), 5-hydroxyindoleacetic acid, and norepinephrine (NE) were unchanged in α6L9'S compared to non-Tg tissue. Western blot analysis revealed increased tyrosine hydroxylase expression in α6L9'S NAc. Overall, these results show that enhanced α6β2* nAChR activity in NAc can stimulate DA production and lead to increased extracellular DA levels.

Measurement of autoclave thermal profiles during high pressure steam de-waxing of investment shells Part 2 - Wax body profiles (2004)

Investment casting research is being carried out by the University of Birmingham, sponsored by EPSRC and a consortium of industrial companies. The programme is aimed at developing a fundamental understanding of the process, with a view to routinely producing sound, net shape castings. A key stage within the investment process is that involving the removal of wax from the unfired ceramic shell. This important process is carried out within the confines of a sealed pressure vessel, more commonly referred to as a Boilerclave*, with external pressure gauges as the only indication of what is actually happening inside the cavity. The de-wax stage is a key stage in the process as wax needs to be removed from a weak ceramic shell system without cracking or dimensional alterations, which would be reflected in out of tolerance casting scrap. Due to the nature of the process, wax removal is probably the least understood or controlled aspect of the whole investment sequence. The following paper is the second of two which contain results obtained at The University of Birmingham using a specially instrumented stream autoclave which allows visual data capture, thermal and steam pressure profiles within the chamber, and thermal instrumentation of waxes and shells to be obtained. Results of thermal and pressure profiles within individual wax components are presented and implications of these results upon the mechanism of wax removal and the effect upon ceramic shells are discussed.
Two aspects of the validation and verification of knowledge-based systems (1993)

Two research projects that have examined problems related to system verification and validation and the associated issue of maintenance are described. The Mekas (Methodology for Knowledge Analysis) Project has developed a method to give knowledge engineers a thorough characterization of the domain, that is, a full description of the ontology, structure, functions, and theories that underpin the domain. This provides a coherent framework within which a knowledge base can be more readily identified with key aspects of the domain, aiding verification and validation. The second project, known as MAKE (Maintenance Assistance for Knowledge Engineers), was aimed at the process of constructing and revising the knowledge base. It is argued that the primary focus of verification and validation must be on the models, and the transitions between them, rather than simply on the executable representation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Cytochrome P-450—Its Role in Oxygen Activation for Drug Metabolism (1977)

At this time many of our colleagues are directing their attention (1,2) to evaluating the existence of oxygen on the planet Mars - an effort dictated by the desire to learn whether any life form, as we know it, exists on that planet. What is it that confers on oxygen special properties that make it so critical for the functioning of cellular metabolism. Much has been written on the "fitness of oxygen" (3) pointing to the capability to metabolically reduce atmospheric oxygen to hydrogen peroxide or water by two or four electron transfer processes, respectively. More important to the topic of this symposium is the ability to enzymatically "activate" molecular oxygen, permitting the incorporation of one atom of oxygen into an organic substrate molecule concomitant with the reduction of the other atom of oxygen to water. The enzyme systems responsible for catalyzing these types of reactions (Figure 1) are termed
Theoretical basis for design of thermal-stress-free fasteners (1983)

A theoretical basis was developed for the design of fasteners which are free of thermal stress. A fastener can be shaped to eliminate the thermal stress which would otherwise result from differential thermal expansion between dissimilar fastener and sheet materials for many combinations of isotropic and orthotropic materials. The resulting joint remains snug, yet free of thermal stress at any temperature, if the joint is uniform in temperature, if it is frictionless, and if the coefficients of thermal expansion of the materials do not change with temperature. In general, such a fastener has curved sides; however, if both materials have isotropic coefficients of thermal expansion, a conical fastener is free of thermal stress. Equations are presented for thermal stress free shapes at both initial and final temperature, and typical fastener shapes are shown.
Effect of antenna capacitance on the plasma characteristics of an internal linear inductively coupled plasma system (2008)

This study examined the effect of the antenna capacitance of an inductively coupled plasma (ICP) source, which was varied using an internal linear antenna, on the electrical and plasma characteristics of the ICP source. The inductive coupling at a given rf current increased with decreasing antenna capacitance. This was caused by a decrease in the inner copper diameter of the antenna made from coaxial copper/quartz tubing, which resulted in a higher plasma density and lower plasma potential. By decreasing the diameter of the copper tube from 25to10mm, the plasma density of a plasma source size of 2750×2350mm2 was increased from approximately 8×1010∕cm3to1.5×1011∕cm3 at 15mTorr Ar and 9kW of rf power.
Effective gene transfer oflacZ andP0 into Schwann cells of P0-deficient mice (1999)

Mutations in the gene encoding for the myelinating Schwann cell protein P0 have been linked to inherited peripheral neuropathies, including the Charcot-Marie-Tooth type 1B disease (CMT1B) and Dejerine-Sottas syndrome (DSS). Recently generated mice deficient in the P0 gene (P0-/- mice) resemble cases of CMT1B and DSS with impaired myelin dosage (Martini et al., 1995a). Potential approaches to treat such diseases include the introduction of the normal gene in the nerves of strongly affected patients. In the present study we used P0-/- mice to evaluate the efficiency of a replication-defective, E1-deleted adenovirus vector carrying the lacZ (Ad-RSV-lacZ) or P0 (Ad-RSV-P0) gene to infect abnormally myelinating Schwann cells. The Ad-RSV-lacZ vector suspension was injected into the left sciatic nerve ofPO-/- mice and the nerves examined for beta-galactosidase activity by X-gal histochemistry. Contralateral nerves injected with vehicle solution or non-injected served as controls. Beta-galactosidase activity was detected in nerves injected with the Ad-RSV-lacZ vector up to 2 weeks post-injection. Immunosuppressing the mice with FK506 to decrease the infiltration of activated T-cells in infected nerves lengthened beta-galactosidase activity to 8 weeks, the longest time point examined. Ultrastructural analysis indicated that X-gal crystals were present mostly in abnormally myelinating Schwann cells. These findings demonstrate that an adenovirus vector can successfully infect Schwann cells in P0-/- mice and expression can be maintained for several weeks. The Ad-RSV-P0 suspension was then injected in the sciatic nerve of immunosuppressed P0-/- mice. Two and four weeks post-injection both P0 mRNA and protein could be detected by in situ hybridization and Western blotting in some of the nerves. Furthermore, P0 protein expression was observed in myelin-like structures and onion bulb-like cells by immunohistochemistry. These results indicate that Schwann cells in P0-/- mice can be induced to produce P0 protein after gene transfer. Genetic repair of abnormal Schwann cells by using adenovirus vectors might be a possible technique to treat animal models of inherited peripheral neuropathies.
Robust AC Voltage Controller with Harmonic Elimination for Stand-Alone and Weak-Grid-Connected Operation (2018)

This paper presents an ac voltage controller with a high robustness to plant model variations which can operate under a wide range of loads. A robust voltage controller is required in a droop-controlled inverter which operates in island mode with other generators or is connected to a grid. In such modes of operation, the voltage source converter (VSC) can experience a large variation in the load impedance depending on the number of parallel generators or the grid impedance value. The proposal improves the transient performance by selectively minimizing the output impedance of the system at the frequencies which typically contain the largest components of the output current. Complete harmonic control is achieved due to its zero output impedance at a set of design-selected frequencies. The design process only requires, as input parameters, the LC filter values, the sampling frequency, and a set of harmonics where load-current circulation is expected.

Physical and Functional Properties of Airway Secretions in Cystic Fibrosis – Therapeutic Approaches (1995)

The airway secretions which line the respiratory tract form a biphasic layer composed of an aqueous 'sol' layer and a more superficial 'gel' layer. In the sol layer, also described as the 'periciliary' layer or 'airway surface fluid', the cilia beat and relax. The lubricant sol layer enables the gel mucus present at the tips of the cilia to be transported by the ciliary beating of the ciliated cells. Due to difficulties with sampling, little is known about the physical and biochemical properties of the sol layer. The gel layer is composed of high molecular weight glycoproteins (mucins) linked with proteins and lipids. They form a gel network with a high water content (95%) and rheologic and physical properties (viscoelasticity, adhesivity) adapted in normal conditions to protect the airway mucosa, particularly through mucociliary transport. The adhesive properties of mucus, which are influenced by its lipid composition and degree of hydration, are very important in controlling the efficacy of mucus transport through ciliary activity and coughing. An intermediate viscosity and elasticity is required for optimal mucociliary transport. In obstructive airway diseases, either of genetic origin, such as cystic fibrosis (CF), or acquired (acute or chronic bronchitis), and particularly during inflammatory and infectious episodes, mucus dehydration is associated with an increase in secreted or transudated molecules and with marked augmentation of DNA content. These abnormalities contribute to the increased viscosity and adhesivity of the airway secretions and are responsible for their abnormally low transport rate by ciliary activity and for inefficient cough clearance. In view of these alterations in the physical and functional properties of CF airway secretions, pharmacologic approaches should aim to rehydrate the mucus and to restore normal mucociliary or cough transport by stimulating chloride ion secretion (i.e. using UTP or ATP associated with amiloride in order to block sodium ion and water reabsorption). During acute episodes of infection, recombinant human DNase (rhDNase) may rapidly prevent mucus stasis by improving its rheologic properties. Lubrication of the mucus at the sol phase interface by 'surfactant' therapy may also represent a very promising therapeutic perspective to reduce the hyperviscosity and hyperadhesivity of airway secretions.
Highly Selective Reduction of Carbon Dioxide to Methane on Novel Mesoporous Rh Catalysts (2018)

Mesoporous metals with high surface area hold promise for a variety of catalytic applications, especially for the reduction of CO<sub>2</sub> to value-added products. This study has used a novel mesoporous rhodium (Rh) nanoparticles, which were recently developed via a simple wet chemical reduction approach ( Nat. Commun. 2017, 8, 15581) as catalyst for CO<sub>2</sub> methanation. Highly efficient performance and selectivity for methane formation are achieved due to their controllable crystallinity, high porosity, high surface energy, and large number of atomic steps distributions. The mesoporous Rh nanoparticles, possessing the largest surface area (69 m<sup>2</sup> g<sup>-1</sup>), exhibit a substantially higher reaction rate (5.28 × 10<sup>-5</sup> mol<sub>CO<sub>2</sub></sub> g<sub>Rh</sub><sup>-1</sup> s<sup>-1</sup>) than the nonporous Rh nanoparticles (1.28 × 10<sup>-5</sup> mol<sub>CO<sub>2</sub></sub> g<sub>Rh</sub><sup>-1</sup> s<sup>-1</sup>). Our results indicate the extensive use of mesoporous metals in heterogeneous catalysis processes.
Nuclear Factor- κ B Activation in Alveolar Macrophages Requires I κ B kinase- β, but Not Nuclear Factor- κ B Inducing Kinase (2002)

Cytokine mediated activation of alveolar macrophages (AMs) is an important event in the pathogenesis of fibrosing alveolitis (FA). Through membrane-associated antigens, cytokines (e.g., tumor necrosis-factor-alpha and interleukin-1) are believed to activate a common kinase cascade that initiates the cytoplasmic degradation of IkappaB and nuclear translocation of "nuclear factor-kappaB" (NF-kappaB). In the nucleus, NF-kappaB promotes the transcription of genes encoding chemokines and cytokines involved in chronic inflammation. Preventing cytokine-mediated NF-kappaB activation is a potential strategy for attenuating the lung injury that occurs in FA. Previously, we have demonstrated that, unlike AMs from healthy volunteers, AMs from patients with inflammatory lung diseases express the coxsackie/adenovirus receptor and the alphav integrins required for adenovirus (Adv) infection. This property allows Adv-mediated transgene delivery to diseased, but not normal, AMs and analysis of molecular pathways involved in gene transcription. In this study, AMs were infected with Adv constructs expressing a defective beta subunit of IkappaB kinase (AdvIKKbetakd) and a defective NF-kappaB inducing kinase (AdvNIKkd) to investigate the contribution of these molecules to NF-kappaB activation. We observed that IKKbeta, but not NIK, was required for NF-kappaB activation. The results of this study identify IKKbeta, but not NIK, as a potential therapeutic target in diseases that involve NF-kappaB-dependent gene transcription.

The effects of the brown ear‐tick, Rhipicephalus appendiculatus, on milk production of Sanga cattle (1997)

Lactating Sanga cows of the Mashona breed from Zimbabwe, receiving either a low or high level of nutritional supplement, were exposed to two levels of infestation of adults of the brown ear-tick, Rhipicephalus appendiculatus in the highveld of Zimbabwe. The effect of the ticks on the milk yield was measured over an 11-week period during the rainy season from January to April 1986. A technique in which calves were weighed before and after suckling was used to estimate milk yield. There were significant treatment effects of ticks (P < 0.05) on milk production but no significant differences in liveweight gain between calves from tick-free and tick-infested dams. The loss in milk production was poorly related to the number of female ticks that engorged, being 9 g (SEM 4) per tick. A Friesian x Hereford (Bos taurus) reference group of cattle carried 50% more ticks than the Mashona cows, illustrating a difference in resistance between the breeds. Thirteen screw-worm (Chrysomya bezziana) strikes were recorded amongst the thirty-two Mashona cows compared with twenty-one amongst the ten Friesian x Hereford animals between January and the end of March.
