Management of Engineering Projects (1988)

This chapter begins with an explanation of the alternative forms of organisation, and their appropriateness for the management of different kinds of project. This is followed by looking at some of the problems arising in project management. The next part of this section examines the skills and attributes required in project managers. The final section looks at aspects of the project management process—that is, achieving the project objectives of cost, time and budget through other people. The Bibliography contains details of further reading that covers project management in more detail. The functions of the project manager and project leader were defined in Chapter 1, section 1.1, this chapter assumes that both these roles will be taken by a single project manager; indeed for a small project these and other roles will be taken by the project engineer. A further definition that is needed for this chapter is the Line Manager: the person who is responsible for a particular function within a company. The line manager usually has no project responsibilities, and a project manager will request functions to be performed by the line manager’s department or section. Functional Manager or Departmental Manager are synonymous with Line Manager.
Formation of Optical Films by Photo-Polymerisation of Liquid Crystalline Acrylates and Application of These Films in Liquid Crystal Display Technology (2005)

ABSTRACT Photo-polymerisation of liquid crystalline di-acrylates is a very versatile method to produce homogeneously aligned polymer films. The orientation of the liquid crystals and hence the anisotropic optical properties of the films are frozen in by the photo-polymerisation process. Homogeneously aligned nematic liquid crystals form birefringent films that find application as retarders, while splayed nematic liquid crystalline mixtures form angle dependent birefringent films that find application as wide viewing angle foils. In addition, cholesteric liquid crystals form reflecting films that can be used as colour filters or polarisers and smectic liquid crystals form highly ordered films that find application as polarisers. Moreover, modulating the light during the manufacturing process either in lateral or in-depth direction of the film can create complex structures not attainable with liquid crystalline polymers. All these films are mechanically, thermally and chemically stable and therefore very suitable to be processed in liquid crystal display manufacturing as additional films or as in-cell optical components.
[Post-infarct myocardial remodelling: from experimental data to the prevention of heart failure]. (1990)

Structural and biochemical modifications of the myocardium (remodeling) occur after acute myocardial infarction. An important part of this process of myocardial remodeling takes place in the interstitial compartment which is composed mainly of fibrillar collagen. These remodeling changes are associated with modifications in left ventricular geometry and function that could be deleterious and have significant clinical manifestations. Some salutary effects of the treatment are related to modifications of the process of interstitial remodeling. Clinical studies with calcium channel antagonists, nitrates and, specially converting enzyme inhibitors have shown significant improvement in the degree of ventricular dilation, hemodynamics and exercise tolerance as a compared to placebo treated patients. Ongoing clinical studies will provide us with more definite information on the effects of converting enzyme inhibitors on long term prognosis as well as on myocardial remodeling after acute myocardial infarction.
Pathophysiology of Campylobacter enteritis (1986)

Abstract : Campylobacter jejuni has exploded from obscurity to be recognized as a major human enteric pathogen. This recognition has triggered numerous bacteriological investigations, but the many mysteries and surprises associated with the organism will challenge the creative efforts of scientists for years to come. This reprint discusses the pathophysiology of the enter-opathogen. Reprints.
Somatosensory Evoked Potentials in Patients With Primary Premature Ejaculation (1997)

Patients with premature ejaculation have hypersensitivity and hyperexcitability of the glans penis, which may give rise to uncontrolled ejaculation and are believed to be organic implications for premature ejaculation.
Modular and Chemoselective Strategy for the Direct Access to α-Fluoroepoxides and Aziridines via the Addition of Fluoroiodomethyllithium to Carbonyl-Like Compounds (2019)

An expeditious, high-yielding synthesis of rare α-fluoroepoxides and α-fluoroaziridines through the addition of the unkown fluoroiodomethyllithium (LiCHIF)-formed via deprotonation the commercially available fluoroiodomethane with a lithium amide base-to carbonyl-like compounds is documented. The ring-closure reactions, leading to α-fluorinated three-membered heterocycles, rely on the diversely reactive C-I and C-F bonds. Excellent chemoselectivity was observed in the presence of highly sensitive functionalities-aldehyde, ketone, nitrile, alkene-which remained untouched during the homologation sequence.
Templatgesteuerte Synthese eines polymeren, Aminosäuresequenz-spezifischen Rezeptors (1999)

Polymere Rezeptoren, die durch eine Kombination von kovalentem und nichtkovalentem Prägen hergestellt wurden, weisen eine hohe Selektivität für die Templat-Aminosäuresequenz auf (siehe schematische Darstellung des gebundenen Tripeptids Lys-Trp-Asp).
Effects of Sample Dilution and Particle Size/Morphology on Diffuse Reflection Spectra of Carbohydrate Systems in the Near- and Mid-Infrared. Part II: Durum Wheat (1993)

It is shown that reduction of particle size for ground durum wheat does not cause a concomitant decrease in the amount of specular reflection observed in the mid-infrared spectrum of the neat sample. Specular reflection can be reduced, but not completely eliminated, by dilution of the wheat in a nonabsorbing matrix such as KCl. The lack of dependence of mid-infrared diffuse reflection spectra of neat ground durum wheat on particle size is explained by the morphology of the surface of each particle and the low effective depth of penetration of mid-infrared radiation into particles of very high absorptivity. It is concluded that mid-infrared diffuse reflection spectra of wheats do not provide information characteristic of the overall composition of the wheat when the particle size exceeds a few micrometers, but that near-infrared diffuse reflection spectra will provide representative analytical data even when the particle size is large.
Effect of Fasting, Glucose, Amino Acids and Food Intake on In Vivo Insulin Release in the Chicken (1978)

Orientation of a bi-leaflet prosthesis (BLP) might influence coronary perfusion. The aim of this study was to investigate the influence of the orientation on coronary perfusion pressure during hyperemia and adrenergic stimulation. During hyperemia perfusion pressure determines coronary blood flow. Fourteen patients with normal coronary angiogram underwent aortic valve replacement (AVR) by a BLP, and seven received a bio-prosthesis. Patients receiving a BLP were randomized to either orientation A (hinge mechanism perpendicular to a line drawn between the coronary ostia) or B (hinge mechanism parallel to the line between the ostia). Six months after surgery all patients underwent cardiac catheterization. Pressures were measured during resting conditions, during maximum hyperemia, and during maximum adrenergic stimulation with a guiding catheter in the aortic arch (Pao), simultaneously with a sensor tipped guide wire in the coronary artery (Pcor) and in the aortic root (Proot). Pao-Proot described a flow-induced pressure drop in the aortic root (Venturi effect) and the gradient Proot-Pcor described coronary ostium abnormalities. Only small non-significant differences in myocardial perfusion pressure were found between different orientations of a bi-leaflet prosthesis or between bi-leaflet prostheses and bio-prostheses in Pao-Proot and Proot-Pcor.
SpraySyn—A standardized burner configuration for nanoparticle synthesis in spray flames (2019)

In many scientific communities, the definition of standardized experiments has enabled major progress in process understanding. The investigation of the spray-flame synthesis of nanoparticles at a well-defined standard burner by experiment and simulation makes it possible to produce a comprehensive data set with various established and novel measuring methods. In this work, we introduce the design of the SpraySyn burner as a new standard for a free-jet type burner that offers well-defined and simulation-friendly boundary conditions and geometries as well as accessibility for optical diagnostics. A combustible precursor solution is fed through a centrally located capillary and aerosolized with an oxygen dispersion gas flow. The spray flame is stabilized by a premixed flat methane/oxygen pilot flame fed via a porous bronze matrix surrounded by a stabilizing nitrogen coflow emanating through the same porous matrix, providing easy-to-calculate boundary conditions for simulations. This burner design enables the use of a wide choice of solvents, precursors, and precursor combinations. Best-practice operating instructions and parameters are given, and large-eddy simulations are performed demonstrating the suitability of the SpraySyn burner for computational fluid dynamics simulations. For ensuring reproducible operation across labs, we define a consumer-camera-based flame characterization scheme for the quantitative assessment of the flame geometry such as flame length, diameter, tilt angle, and photometric distribution of visible chemiluminescence along the center axis. These parameters can be used for benchmarking the pilot and spray flame by each user of the SpraySyn burner with the reference flames.

Australian mosquitoes from which Japanese encephalitis virus (JEV) has been recovered (Culex annulirostris, Culex gelidus, and Aedes vigilax) were assessed for their ability to be infected with the ChimeriVax-JE vaccine, with yellow fever vaccine virus 17D (YF 17D) from which the backbone of ChimeriVax-JE vaccine is derived and with JEV-Nakayama. None of the mosquitoes became infected after being fed orally with 6.1 log(10) plaque-forming units (PFU)/mL of ChimeriVax-JE vaccine, which is greater than the peak viremia in vaccinees (mean peak viremia = 4.8 PFU/mL, range = 0-30 PFU/mL of 0.9 days mean duration, range = 0-11 days). Some members of all three species of mosquito became infected when fed on JEV-Nakayama, but only Ae. vigilax was infected when fed on YF 17D. The results suggest that none of these three species of mosquito are likely to set up secondary cycles of transmission of ChimeriVax-JE in Australia after feeding on a viremic vaccinee.
A role of trophoblastic cells in regulation of mouse blastocyst survival in vitro after microinjection and osmotic stress (2014)

We have evaluated the morphology of the mouse preimplantation embryos at developmental stages from morula to late-blastocyst after two different impacts: microinjection of modified Witten's medium and osmotic stress in physiological osmolarity (310 mOsM), in 5% glucose (560 mOsM) at high concentration of NaCl (614 mOsM). Results of our research showed that these stresses caused similar changes in embryo morphology: volume was reduced followed by its recovery in culture medium (osmolality was less than a physiological value, 260 MOsM). The ability of embryos to recover the volume and morphology up to the initial level depends on a stage of embryo development and consequently competence of TB cells. In this study it was revealed that a key role in regulation of volume homeostasis after microinjection and after short-time (30-60 min) osmotic stress belongs to TB cells. Both physical effects induce the further embryo development in vitro up to the formation of primary colonies of embryonic and trophoblastic cells. These data could be used to develop the morphological criteria for a prediction of blastocyst-stage embryonic implantation potential.
Smoothing Filter-based Intensity Modulation: A spectral preserve image fusion technique for improving spatial details (2000)

Image fusion techniques are widely used to integrate a lower spatial resolution multispectral image with a higher spatial resolution panchromatic image, such as Thematic Mapper (TM) multispectral band and SPOT Panchromatic images. However, the existing techniques either cannot avoid distorting the image spectral properties or involve complicated and time-consuming frequency decomposition and re-construction processing. A simple spectral preserve fusion technique: the Smoothing Filter-based Intensity Modulation (SFIM) has thus been developed based on a simplified solar radiation and land surface reflection model. By using a ratio between a higher resolution image and its low pass filtered (with a smoothing filter) image, spatial details can be modulated to a co-registered lower resolution multispectral image without altering its spectral properties and contrast. The technique can be applied to improve spatial resolution for either colour composites or individual bands. The fidelity to spectral property and the spatial textural quality of SFIM are convincingly demonstrated by an image fusion experiment using TM and SPOT Panchromatic images of south-east Spain. The visual evaluation and statistical analysis compared with HSI and Brovey transform techniques confirmed that SFIM is a superior fusion technique for improving spatial detail of multispectral images with their spectral properties reliably preserved.
Novel Water-base Mud for Shale Gas, Part II: Mud Formulations and Performances (2012)

Abstract Shale-gas plays and other unconventional resources have gained significant importance worldwide. Historically, synthetic based drilling fluids (SBM) are used in these plays when no environmental concerns are in place and are preferred when wellbore stability is necessary. In this paper, we study the use of an improved water based drilling fluid (WBM) that is simple in formulation and maintenance that shows excellent rheological properties, maintains wellbore stability, and a good environmental profile. A combination of well-known and economically affordable materials is combined with new technology to achieve desired rheological properties and wellbore stability. The use of nanoparticles to decrease shale permeability by physically plugging nanoscale pores holds the potential to remove a major hurdle in confidently applying water-based drilling fluids in shale formations, adding a new advantage to the studied fluid. Silica nanomaterials were investigated for this purpose. Due to their commercial availability, these materials can be engineered to meet the specifications of the formation. Characterization of the nanoparticles was completed with Transmission Electron Microscopy (TEM), dynamic light scattering, and X-ray-photoelectron spectroscopy. Rheological properties and fluid loss are studied together with other important properties such as shale stability and anti-accretion properties. The authors will describe new laboratory methods used to investigate these properties, from a modified API fluid loss test to the Shale Membrane Test that measures both fluid loss and plugging effects and illustrate additional future research that includes adding reactive species, and anchoring them to the pores, thus stabilizing the shale further.
The Role of Microorganisms and Carbon-to-Nitrogen Ratios for Microbial Protein Production from Bioethanol (2022)

With industrial agriculture increasingly challenging our ecological limits, alternative food production routes such as microbial protein (MP) production are receiving renewed interest. Among the multiple substrates so far evaluated for MP production, renewable bioethanol (EtOH) is still underexplored. Therefore, the present study investigated the cultivation of five microorganisms (2 bacteria, 3 yeasts) under carbon (C), nitrogen (N), and dual C-N-limiting conditions (molar C/N ratios of 5, 60, and 20, respectively) to evaluate the production (specific growth rate, protein and biomass yield, production cost) as well as the nutritional characteristics (protein and carbohydrate content, amino acid [AA] profile) of MP production from bioethanol. Under C-limiting conditions, all the selected microorganisms showed a favorable AA profile for human nutrition (average AA score of 1.5 or higher), with a negative correlation between protein content and growth rate. Maximal biomass yields were achieved under conditions where no extracellular acetate was produced. Cyberlindnera saturnus and Wickerhamomyces anomalus displayed remarkably high biomass yields (0.40 to 0.82 g cell dry weight [CDW]/g EtOH<sub>consumed</sub>), which was reflected in the lowest estimated biomass production costs when cultivated with a C/N ratio of 20. Finally, when the production cost was evaluated on a protein basis, Corynebacterium glutamicum grown under C-limiting conditions showed the most promising economic outlook. <b>IMPORTANCE</b> The global protein demand is rapidly increasing at rates that cannot be sustained, with projections showing 78% increased global protein needs by 2050 (361 compared to 202 million ton<sub>protein</sub>/year in 2017). In the absence of dedicated mitigation strategies, the environmental effects of our current food production system (relying on agriculture) are expected to surpass the planetary boundaries-the safe operating space for humanity-by 2050. Here, we illustrate the potential of bioethanol-renewable ethanol produced from side streams-as a main resource for the production of microbial protein, a radically different food production strategy in comparison to traditional agriculture, with the potential to be more sustainable. This study unravels the kinetic, productive, and nutritional potential for microbial protein production from bioethanol using the bacteria Methylorubrum extorquens and Corynebacterium glutamicum and the yeasts <i>Wickerhamomyces anomalus,</i> Cyberlindnera saturnus, and Metschnikowia pulcherrima, setting the scene for microbial protein production from renewable ethanol.
A Survey of Watermarking Algorithms for Image Authentication (2002)

Digital image manipulation software is now readily available on personal computers. It is therefore very simple to tamper with any image and make it available to others. Insuring digital image integrity has therefore become a major issue. Watermarking has become a popular technique for copyright enforcement and image authentication. The aim of this paper is to present an overview of emerging techniques for detecting whether image tampering has taken place. Compared to the techniques and protocols for security usually employed to perform this task, the majority of the proposed methods based on watermarking, place a particular emphasis on the notion of content authentication rather than strict integrity. In this paper, we introduce the notion of image content authentication and the features required to design an effective authentication scheme. We present some algorithms, and introduce frequently used key techniques.
Combustion Synthesis of a Nickel Supported Catalyst: Effect of Metal Distribution on the Activity during Ethanol Decomposition (2012)

Solution combustion synthesis method is used to prepare Ni catalysts supported on γ-Al2O3 pellets with controlled metal distribution. It was shown that impregnation time of the SCS solution onto the pellet determines the distribution of the Ni in the pellet which in turn affects the catalyst selectivity toward hydrogen production during ethanol decomposition.

Insecticidal effect of the entomopathogenic nematode Heterorhabditis megidis (Nematoda: Heterorhabditidae) baited from the soil on the larvae of Monochamus alternatus (Coleoptera: Cerambycidae) (2023)

Abstract To scout for an entomopathogenic nematode (EPN) that effectively controls the pine sawyer beetle, Monochamus alternatus Hope (Coleoptera: Cerambycidae), we screened EPNs from soil samples using M. alternatus larvae as bait. A population of the nematode obtained was named isolate SOz01, and molecularly identified as Heterorhabditis megidis Poinar, Jackson and Klein (Nematoda: Heterorhabditidae). In the inoculation test of the infective juveniles (IJs) of SOz01 onto mature larvae of M. alternatus under laboratory conditions, a mortality of 86–100% occurred when more than 20 IJs were inoculated. Even when the larvae were inoculated with only five IJs, one-third of them died. This finding suggests that H. megidis SOz01 has a strong insecticidal effect on M. alternatus .
Enhanced adsorption removal of phosphate from water by Ag-doped PVA-NiO nanocomposite prepared by pulsed laser ablation method (2022)

Phosphate exists concurrently in multiple waste streams. Embedded nickel oxide in polyvinyl alcohol (NiO/PVA) was doped by silver nanoparticles (Ag) to generate an Ag-doped NiO/PVA nanocomposite structure prepared by multiple laser ablation process technique for removing phosphate. Different techniques were used to characterize the physicochemical properties of the substance. The characterization results of the prepared nanocomposites showed that NiO and Ag were successfully integrated into the PVA structure. They confirmed the production of hybrid nanocomposites by a reduction in the peak height due to intramolecular and intermolecular interactions with Ag nanoparticles from Raman spectra. Also, the shift in the absorbance transition characteristic and the appearance of vibrational motions of NiO and Ag confirmed the successful interaction between PVA, Ag, and NiO. After that, in the adsorption study, the most important aspect of the investigation was a series of phosphate adsorption tests from aqueous solutions, which showed that the efficiency of the adsorption process is dependent on the concentrations of the adsorbate and adsorbent, the pH, the reaction time, and the temperature. The results indicate that the current Ag-doped NiO/PVA nanocomposite adsorbent has the capacity to control phosphorus contamination in water.
Tangential, semisubmerged, and internal store carriage and separation (1992)

Accounts are presented of tangential, semisubmerged, and internal store carriage drag, as well as of the results to date of stores-separation investigations employing both computational and experimental methods. It is demonstrated that CFD can contribute to the data base needed for internal stores carriage design and trade studies. Attention is given to the case of an internally carried store separating from its bay at supersonic speeds, where various kinds of interference are encountered. A code is developed for the simulation of these unsteady flows through time-accurate computations; computation results are noted to closely reproduce experiment data.
