i-Merc: A Mobile Robot to Deliver Meals inside Health Services (2006)

With the aim of increasing the quality of the meals transportation service inside hospitals and health care centers (HHCC), we are developing a dedicated mobile robot to perform this service, the i-Merc. This robot is equipped with a heating system in the meals compartment which guarantees the meals temperature and prevents bacteriologic proliferation. The i-Merc also integrates a personalized diets information system where information about patients' diets can be introduced and accessed by the service personnel. This project has been developed within the compass of the Master in Engineering Design, at the Technical University of Lisbon. The product development of the robot addressed many knowledge areas, some of which are presented in this paper. We finished the first stage of the project with a service concept, a virtual prototype which included some key specifications and a physical prototype. Presently, we are continuing the product development and searching some stakeholders that would be interested in the project
Immunochemical Characterization of the Polysaccharide Antigens of Group B Streptococci (1988)

Mouse monoclonal antibodies were used in the immunochemical characterization of the polysaccharide antigens of group B streptococci (GBS). Monoclonal antibodies specific for the sialylated form of the GBS type III polysaccharide were highly protective in a mouse model of GBS type III infection, whether of IgM, IgG2a, or IgA isotypes, but monoclonal antibodies specific for the nonsialylated form of the type III antigen were not protective, regardless of isotype. Monoclonal antibodies reacting with the type II polysaccharide antigen could be divided into two general antigen binding groups on the basis of the ability of beta-methylgalactopyranoside to inhibit their binding to purified type II antigen. Various proportions of antibodies with the two specificities were observed in rabbit and human sera. Although it was previously reported that rabbit antisera could not distinguish between the sialylated and nonsialylated forms of the type Ib polysaccharide, mouse monoclonal antibodies were found to exhibit exclusive specificity for one or the other form of the antigen. Only monoclonal antibodies specific for the sialylated Ib polysaccharide were protective in a mouse model.
Acipimox, a Nicotinic Acid Analog, Stimulates Growth Hormone Secretion in Short Healthy Prepubertal Children (2000)

Recent studies in adult volunteers have demonstrated that the free fatty acid reduction induced by acipimox, a nicotinic acid analog, stimulated GH secretion per se and enhanced in an additive manner the GH secretion elicited by such different stimuli as pyridostigmine, GHRH and GHRP-6. In order to evaluate whether acipimox administration stimulates GH secretion in prepubertal children, we administered a single oral dose of acipimox (100 mg for children weighing <30 kg and 200 mg for those >30 kg) to 14 healthy prepubertal children with a mean age of 8.2 +/- 1.9 years, a mean bone age of 6.2 +/- 3.0 years, growing along the 5-10th percentiles, and with normal thyroid function and IGF-I levels. Acipimox administration elicited a sustained increase in GH from a mean baseline level of 0.6 +/- 0.4 to 6.7 +/- 2.4 microg/l at the end of the test (p<0.05), with a mean GH peak of 10.5 +/- 3.5 microg/l. GH release was delayed so that peak GH levels were achieved 180 minutes after acipimox administration. In order to determine whether acipimox was capable of enhancing the GH secretion elicited by levodopa (L-Dopa), we administered either oral L-Dopa (250 mg for children weighing <30 kg and 500 mg for those >30 kg) or oral acipimox plus L-Dopa to the same children on different days. GH concentrations increased in a similar fashion following either of these tests (from a baseline level of 1.2 +/- 0.4 and 0.7 +/- 0.4 microg/l to 8.4 +/- 2.7 and 9.3 +/- 2.9 microg/l at the end of the test (p<0.001), with peak GH concentrations of 13.1 +/- 4.1 and 11.8 +/- 3.3 microg/l after L-Dopa or acipimox plus L-Dopa, respectively). Although the peak GH concentrations obtained after the combined administration of acipimox plus L-Dopa were similar to those obtained after either acipimox or L-Dopa administration, a larger number of our patients reached a GH cut-off point of >7 microg/l following combined therapy than with either stimulus alone (13/14 patients with combined therapy and 10/14 with acipimox alone). No side effects other than mild facial flushing were noted after acipimox administration. These results indicate that: 1) following the administration of a single oral dose of acipimox, significant GH secretion was elicited in healthy short prepubertal children; 2) the combined administration of acipimox plus L-Dopa did not, however, enhance the GH secretion of this group of children; 3) acipimox was well tolerated with minimal side effects; and 4) further studies in both GH sufficient and GH deficient children are necessary to evaluate acipimox's usefulness in assessing GH reserve.

A Taguchi experimental design study of twin-wire electric arc sprayed aluminum coatings (1992)

An experimental study was conducted on the twin-wire electric arc spraying of aluminum coatings. This aluminum wire system is being used to fabricate heater tubes that emulate nuclear fuel tubes for use in thermal-hydraulic experiments. Experiments were conducted using a Taguchi fractional-factorial design parametric study. Operating parameters were varied around the typical process parameters in a systematic design of experiments in order to display the range of processing conditions and their effect on the resultant coating. The coatings were characterized by hardness tests, optical metallography, and image analysis. The paper discusses coating qualities with respect to hardness, roughness, deposition efficiency, and microstructure. The study attempts to correlate the features of the coatings with the changes in operating parameters. A numerical model of the process is presented including gas, droplet, and coating dynamics.
Suitability of the Depression, Anxiety, and Stress Scale in Parkinson’s Disease (2016)

Whilst the depression and stress subscales appear suitable in PD, poor loadings and internal consistency indicate the anxiety subscale may not accurately assess anxiety symptomology in PD. This may be due to the scale's reliance on physiological symptoms as indicators of anxiety, when many of these are present in PD. Thus, the anxiety subscale of the DASS-21 may not be a suitable measure of anxiety in PD.
Emission of intense microwave radiation from an automodulated relativistic electron beam (1975)

High−power microwave radiation has been observed from the interaction of an intense relativistic electron beam and a cavity structure. The efficiency of conversion of electron kinetic energy into microwave radiation was about 20% with a total radiated power of order 500 MW. The mechanism responsible for the efficiency production of microwaves is based on a simple physical model.
Novel RC oscillators using the current-feedback operational amplifier (1996)

Novel oscillator circuits using the current-feedback operational amplifier (CFOA) are presented. Each circuit uses one CFOA and five passive elements. Some of the circuits enjoy independent control of the frequency and the condition of oscillation. Experimental results are included.
Aggregative closure: an extension of transitive closure (2003)

The aggregative closure operator is defined and its usefulness is demonstrated in a wide variety of applications. The concepts and definitions of closed semirings and the aggregating relational operators provide a mathematical framework for the presentation of algorithms for these applications. A novel algorithm is also presented which is intended for the computation of the aggregate closure. All of these algorithms but the last are generalizations of existing algorithms intended for transitive closure.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Development of a Four Wheel Independent Drive and Four Wheel Independent Steer Electric Vehicle (2015)

A four wheel independent driving four wheel independent steering electric vehicle was developed. Chassis assembly and electrical system assembly about the vehicle are made thorough introduction of in this paper. Identity power control module is taken as the driving control approach, and both feedforward control keeping sideslip angle zero and feedback control aiming at tracking the ideal model are used as steering control approach. Experiment in various conditions is made to testify the electric vehicle's driving characteristic, handling and stability, and control accuracy. The development of electric vehicle lies a foundation for further systematic study of vehicle dynamics.
A Unified Control Strategy for the Active Reduction of Sound and Vibration (1991)

The generalized minimum variance (GMV) control strategy is proposed as an effective strategy for active sound and vibration control systems. The GMV strategy is shown to unify well-known adaptive filtering approaches based on LMS-type algorithms and purely feedback strategies as used in other types of control systems. The short comings of the LMS adaptive filtering systems for active sound control are clearly un covered. Pure adaptive filtering emerges from the GMV strategy merely when the extra neous noise at the error sensor is Gaussian noise, the controller complexity is restricted and no fast tracking of system changes is required. The necessary additional identification of the secondary acoustic path is an extra problem of the adaptive filtering approach. Sim ulation experiments with real and synthetic data verify the wide applicability of the GMV control strategy and the limited efficacy of (LMS) adaptive filters for use in active sound reduction systems.

Vasodilator Reactivity to Calcitonin Gene-Related Peptide Is Increased in Mesenteric Arteries of Rats during Early Pregnancy (2003)

The objective of the present study was to determine the effect of early pregnancy on the sensitivity to, and endogenous production of calcitonin gene-related peptide (CGRP). Contractile responses of arteries of 10-day pregnant and nonpregnant rats were studied in myographs. During contractions induced by 40 mmol/l K(+), exogenous CGRP elicited an approximately 30% stronger relaxation in mesenteric arteries in pregnancy, an effect not seen in renal and uterine arteries. Capsaicin treatment during K(+)-induced contractions caused a persistent potentiation of the contractile response in mesenteric arteries, indicating that K(+) stimulates the endogenous release of CGRP. This potentiation was similar in the pregnant and nonpregnant state (+81 +/- 23% and +82 +/- 23%, respectively), suggesting no effect of pregnancy on the endogenous CGRP release. The latter was paralleled by comparable CGRP content in the arteries of both groups, indicating similar tissue CGRP availability. The results of this study support the concept that early pregnancy is associated with a rise in the vascular sensitivity to CGRP in selected areas of the vascular bed without concomitant increase in the vascular CGRP production and release.
Mass customization: Implementing the emerging paradigm for competitive advantage (1995)

In many industries the dominant paradigm, ‘mass production,’ is being challenged by the emerging paradigm, ‘mass customization.’ Accordingly, many researchers posit that firms which replace ‘mass production’ with ‘mass customization’ will gain a significant competitive advantage. Based on an in-depth study of the National Bicycle Industrial Company (NBIC), this paper explores the dynamics of pursuing both mass production and mass customization strategies simultaneously. At the operational level, the paper discusses the organizational mechanisms instituted by the NBIC in order to benefit from the simultaneous pursuit of both approaches. At the competitive level, it isolates the relative contributions of both approaches to the overall competitive positioning of this firm in its industry. Based on this discussion, it provides a framework that illustrates the dynamics involved in the pursuit of both approaches. Implicitly, the paper argues that for firms competing in rapidly changing environments the ability to maintain a sustainable competitive advantage depends on the firm's capability to create knowledge by interacting both mass customization and mass production approaches. Finally, the paper concludes with managerial and research implications regarding the emerging paradigm of mass customization.

Synthesis of <i>N</i>‐Aryl‐2‐substituted Tetrahydrobenzimidazoles via Direct <i>N</i>‐Arylation (2007)

Abstract A series of novel N‐aryl‐2‐substituted tetrahydrobenzimidazoles has been synthesized via direct N‐arylation of 2‐substituted tetrahydrobenzimidazoles, which was accomplished by a medium aryl electrophile, 4‐methylsulfonylfluorobenze, in the presence of 37% KF/Al2O3 and 18‐crown‐6 in fair yields under mild reaction conditions. Meanwhile, the hydrogenation of 2‐phenylbenzimidazole was studied.
Mechanisms of human cell-mediated cytotoxicity. I. Modulation of natural killer cell activity by cyclic nucleotides. (1982)

Abstract In the present study we demonstrate the regulation and modulation of human natural killer (NK) cell activity by cyclic nucleotides and their intracellular inducers. The direct addition of the cyclic adenosine monophosphate-(cAMP) inducers dibutyryl cAMP (DB-cAMP), isoproterenol, aminophylline, or histamine to peripheral blood mononuclear cell-K562 cell mixtures at the initiation of a 4-hr 51chromium-release microcytotoxicity assay significantly suppressed NK function in a dose-dependent manner. Cyclic guanosine monophosphate (cGMP) analogs or compounds known to increase the cGMP content of lymphocytes produced a small but significant enhancement of cytotoxic activity. The continuous presence of these agents during the assay was not required for the observed effect. The cAMP and cGMP-induced alteration of killing occurred relatively early in the lytic process and the effects were apparent throughout the assay. Preincubation of effector cells with cAMP or cGMP inducers before the NK assay produced transient, reversible modulation of lysis; the cyclic nucleotide-induced alteration in cytotoxicity lasted only 2 hr before returning to baseline pretreatment values. cAMP and cGMP-induced changes in NK activity were reversible by specific antagonists. Blockade of the surface neurohumoral receptors for isoproterenol and carbachol by propranolol and atropine, respectively, abrogated the attenuation of NK function induced by these autonomic agonists. Experiments employing highly purified fractions of NK-enriched large granular lymphocytes indicated that cAMP- and cGMP-inducing agents affected activity of cytotoxic lymphocytes directly rather than through effects on accessory non-lytic cells. The cyclic nucleotide-induced alterations in NK activity were not due to changes in effector cell viability, target cell binding, or the susceptibility of target cells to lysis. These studies demonstrate the important roles of cyclic nucleotides in modulating NK function and may provide the basis for the eventual elucidation and manipulation of cytotoxic activity in normal and disease states.
2-Hydroxy-4 (Methylthio) Butanoic Acid as a Drinking Water Supplement for Broiler Chicks (1992)

Two experiments were conducted to study the effects on chick performance of a commercially available liquid methionine analog [2-hydroxy-4 (methylthio) butanoic acid; HMB] supplied through drinking water. Methionine activities of .025 and .05% were added to drinking water and compared with levels of .03, .06, or .09% included in a low-methionine basal diet from 0 to 21 days of age. Mortality was not significantly altered by any dietary treatment. Neither feed nor water intake was affected adversely by HMB inclusion in drinking water. Only male body weight in Experiment 1 did not respond to HMB feed supplementation. Equivalent levels of total sulfur amino acid intake among water treatments were associated with significantly heavier body weights than the control. In both experiments, body weight and feed efficiency of birds receiving .05% methionine activity as HMB in water were equal or superior to those of groups that received supplemented feed. The results indicate that, under the study conditions, HMB provided in drinking water can be effectively assimilated by broiler chicks, at least through 21 days of age.
Unbalanced RLC Networks Containing Only One Resistance and One Real Transformer (1953)

Any transfer function, in order to be physically realizable as a lossless coupling network terminated in a single resistance, must have an even or odd polynomial as its numerator. Such a function, representing a transfer admittance, a transfer voltage ratio, or a transfer impedance, can be realized by the method of this paper as a lossless lattice network terminated in resistance and possessing no mutual inductance. If the numerator of the transfer admittance or voltage ratio is even and the numerator of the transfer impedance is odd, these lattices can always be reduced to unbalanced networks. No ideal transformers are needed in final network; only one real transformer is required, where a real transformer is defined as one th%-hn coupling coefficient smaller than one and finite magnetizing inductance.
SALSA: A Framework for Dynamic Configuration of Cloud Services (2014)

Contemporary cloud services are constructed from different types of software and deployed on multiple cloud infrastructures, which offer various configuration options, and can change dynamically at runtime. Due to this complexity, such cloud services require substantial configuration efforts. Currently we lack techniques for automating the complex tasks and providing fine-grained configuration features for multi-cloud services. In this paper, we present a novel multi-level configuration approach for complex cloud services on multi-cloud environments. We develop techniques for automating configuration orchestration activities. Our solution enables the fine-grained configuration at different application abstraction levels and supports the dynamic change of cloud services at runtime. We provide the SALSA framework to implement our approach and demonstrate its usefulness with several real-world services.
Efficient and Selective Hydrogenation of Carboxylic Acid Catalyzed by Ni or Pd on ZSM-5 (2007)

Efficient and selective catalytic systems, where Ni or Pd is introduced on the silicate material (ZSM-5) having micropore and mesopore structures, have been developed for the reduction of carboxylic acids with H2 at room temperature. It is found that the catalytic activity depends on the hydrogen pressure, the agitation rate, the nature and the amount of active species. A plausible reaction mechanism for the hydrogenation of carboxylic acids to corresponding alcohols is proposed on the basis of electronic and steric effects in these reactions.
A Movement of Higher Education Institutions to Consortiums of Institutions Banding Together to Create a Position of Strength. (2013)

Colleges and universities compete for students, faculty, and business, industry, and research partnerships with quality programs, strong faculty, research opportunities, affordable cost, and high student success factors. Yet, at the infrastructure level, most of these institutions provide many similar information technology services and support. On top of this, many of these institutions struggle to provide this quality infrastructure because of a variety of factors, including: shrinking budgets, minimal strategic planning, and a lack of institutional vision of information technology as a strategic asset. This presentation will showcase best practice examples of how higher education institutions can band together, to create strong consortium relationships that can help all partners in this relationship move forward as a strong force. Examples will include actual successes experience by the Kentucky Council on Postsecondary Educations Distance Learning Advisory Committee (DLAC), the Washington Legislative Technology Transformation Taskforce (TTT), and the Washington Higher Education Technology Consortium (WHETC).These successes range from statewide strategic planning efforts, to significant consortial purchasing contracts, to collaborative technology systems, services, and training opportunities. This presentation will show that institutions can be stronger working together than working individually.
An Empirical Evaluation of the MuJava Mutation Operators (2007)

Mutation testing is used to assess the fault-finding effectiveness of a test suite. Information provided by mutation testing can also be used to guide the creation of additional valuable tests and/or to reveal faults in the implementation code. However, concerns about the time efficiency of mutation testing may prohibit its widespread, practical use. We conducted an empirical study using the MuClipse automated mutation testing plug-in for Eclipse on the back end of a small web-based application. The first objective of our study was to categorize the behavior of the mutants generated by selected mutation operators during successive attempts to kill the mutants. The results of this categorization can be used to inform developers in their mutant operator selection to improve the efficiency and effectiveness of their mutation testing. The second outcome of our study identified patterns in the implementation code that remained untested after attempting to kill all mutants.
[Procedure for complex toxico-genetical investigations]. (1997)

A biomonitoring system is proposed, which involves measurement of environmental genetoxicants, determination of mutagenic accumulation in biological substrates of human beings and the severity of genetic abnormalities in their somatic cells. The toxicogenetical monitoring system includes the assessment of the examinees mental status. The results of application of the system are given by using as an example two Yaroslavl (machine-building and oil-processing) plants.
Apparatus Regulates Temperature Between -170 And 100 Degrees C (1994)

Temperature-control apparatus mixes pulses of liquid nitrogen into smoothly flowing nitrogen gas to produce flow of nitrogen gas at controlled low temperature. Mixing chamber provides turbulence, thermal mass, and thermal conductance to promote thermal and mechanical mixing of liquid and gaseous flows and thereby suppresses large transient deviations from set-point temperature.
