SYSTEMATICS OF TRIPSACUM SECTION FASCICULATA (GRAMINEAE) (1983)

Tripsacum section Fasciculata is characterized by staminate spikelet pairs in which one spikelet is sessile and the other is supported by a long and slender pedicel. In section Tripsacum both spikelets of a staminate pair are sessile, or one is supported by a short and stout pedicel. Section Fasciculata includes five closely allied species. Tripsacum lanceolatum Ruprecht ex Fournier (2 n = 72) extends from Durango in Mexico to the Huachuca mountains of southern Arizona. It resembles T. jalapense de Wet & Brink spec. nov. (2 n = 72) from Guatemala in having terminal inflorescences with 3–10 racemes, but they differ in growth habit and are genetically isolated. Terminal inflorescences of the remaining three species have 15–50 racemes. Tripsacum laxum Nash (2 n = 36) from the eastern escarpment of the Central Mexican Plateau is the only species of the group with essentially glabrous basal leaf‐sheaths. It resembles the more widely distributed T. maizar Hernandez & Randolph (2 n = 36, 72) in respect to inflorescence morphology, but is genetically isolated from this species. The widely distributed T. pilosum Scribner & Merrill (2 n = 72) was divided into var. pilosum and var. guatemalense de Wet & Brink var. nov.
Dopant activation in homoepitaxial MgZnO:P thin films (2009)

Homoepitaxial MgxZn1−xO:P thin films with variable magnesium content (x&lt;0.05) have been grown by pulsed-laser deposition. The film compositions have been determined by proton induced x-ray analysis. The phosphorous and magnesium content of the films decreases with increasing oxygen partial pressure during growth. High-resolution x-ray diffraction shows a pseudomorphic growth of the thin films with a nominal MgO content of 2 wt %. Hall-effect measurements show electron mobilities of the as-grown films as high as 820 cm2/V s at 55 K, which compares to the value observed for ZnO:P homoepitaxial thin films. Upon annealing, the free carrier concentration was reduced by several orders of magnitude, depending on the oxygen partial pressure used during growth of the MgZnO:P films, while it remained nearly unchanged in ZnO:P samples. The role of the MgO concentration in the films in acceptor defect formation is discussed.

MULTIOBJECTIVE OPTIMAL DESIGN OF A SIMPLIFIED P4R MECHANISM (1996)

A simplified P4R mechanism, which is believed to be new, is presented. This mechanism has base-mounted actuators and for a given displacement at any output point along its output link, the required actuator displacements can be found very easily. An optima! design model of the mechanism with two design objectives is developed in order to (i) minimize a measure of the actuator torques, and (ii) maximize the workspace area. The requirements on dexterity, singluarity, and size of the mechanism form the constraints of the model. Several design tradeoff solutions with the same dexterity are reported.
An efficient neural network architecture for recognition of spatial pattern invariants (2003)

The authors describe a neural architecture for efficient recognition of invariant features placed arbitrarily in patterns of data. The architecture provides versatility in invariant selection with minimal computation and storage requirements. Operating in dumb mode, the architecture, called the big, dumb mass detector (BDMD), autonomously extracts fixed-size subsets of pattern components based upon total activation in the receptive fields of detector nodes. The BDMD sends these subset patterns to a pattern recognition neural network (PR network, an ART system) whose input field has exactly as many nodes as the fixed-size subsets. Operating in smart mode, the BDMD can be driven by another part of the recognition system to selectively scan an input pattern. Among the capabilities of the BDMD is its ability to zoom in on a pattern feature of particular interest. Only the relatively few connections and associated computations required for recognizing single features need to be implemented in the PR network.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Identifiying New Technologies, Products and Strategies for Resource Efficiency (2010)

Abstract New technologies can be the basis for resource‐efficient products and services and thus create eco‐innovations, either by creating new functionalities in existing or new application fields or by substituting existing technologies in existing or new application fields. In this paper, an overview over different technology fields, products and strategies with resource efficiency potential, such as nanotechnologies, material science, manufacturing technologies, process technologies and cross‐cutting issues, is presented. There is a special focus on applications from nanotechnology issuing, e.g. functional surfaces or new ‘smart' materials with special functionalities. Furthermore, it is shown how companies can use the method Resource Efficiency Technology Radar to identify and evaluate technologies with resource efficiency in order to incorporate them into their development activities.
Expandable Silicone Implants for Scleral Buckling (1973)

Experimental scleral buckling was obtained in rabbits by using expanded silicone rubber implants under scleral trap doors. Buckle heights ranged from 2.3 to 4mm after injection of 0.05 to 0.15 ml of fluid into the implants. Therate of decrease in buckle height followed up opthalmoscopically for five months, was found to be slow and continous and was caused mainly by loosening by the scleral flaps rather than by the diffusion of fluid from the implants. Implants expanded with chorampenicol solutions provided sustained release of the antibiotic in the area of the operation. This was confirmed in agar plantes by inhibition of the growth of Sarcina lutea around subimplant tissues and the expanded implants that were recovered post mortem. These implants provided an opportunity of modify the buckle height easily, either during the procedure or postoperatively.
Genomics, Transcriptomics, and Peptidomics of<i>Daphnia pulex</i>Neuropeptides and Protein Hormones (2011)

We report 43 novel genes in the water flea Daphnia pulex encoding 73 predicted neuropeptide and protein hormones as partly confirmed by RT-PCR. MALDI-TOF mass spectrometry identified 40 neuropeptides by mass matches and 30 neuropeptides by fragmentation sequencing. Single genes encode adipokinetic hormone, allatostatin-A, allatostatin-B, allatotropin, Ala(7)-CCAP, CCHamide, Arg(7)-corazonin, DENamides, CRF-like (DH52) and calcitonin-like (DH31) diuretic hormones, two ecdysis-triggering hormones, two FIRFamides, one insulin, two alternative splice forms of ion transport peptide (ITP), myosuppressin, neuroparsin, two neuropeptide-F splice forms, three periviscerokinins (but no pyrokinins), pigment dispersing hormone, proctolin, Met(4)-proctolin, short neuropeptide-F, three RYamides, SIFamide, two sulfakinins, and three tachykinins. There are two genes for a preprohormone containing orcomyotropin-like peptides and orcokinins, two genes for N-terminally elongated ITPs, two genes (clustered) for eclosion hormones, two genes (clustered) for bursicons alpha, beta, and two genes (clustered) for glycoproteins GPA2, GPB5, three genes for different allatostatins-C (two of them clustered) and three genes for IGF-related peptides. Detailed comparisons of genes or their products with those from insects and decapod crustaceans revealed that the D. pulex peptides are often closer related to their insect than to their decapod crustacean homologues, confirming that branchiopods, to which Daphnia belongs, are the ancestor group of insects.
Human herpesvirus‐6: A survey of presence and distribution of genomic sequences in normal brain and neuroglial tumors (1995)

In an attempt to study the frequency and distribution of human herpesvirus-6 (HHV-6) infection both in normal and neoplastic brain tissues in vivo, polymerase chain reaction was used to look for HHV-6 genomes: 1) in samples, obtained at necropsy, from different regions of the brain of immunocompetent adult subjects and of patients who died of AIDS; 2) in the surgical biopsies of a well-characterized series of primary brain tumors of neuroglial origin. HHV-6-specific sequences were identified in six of nine brain samples from immunocompetent subjects, and in four of seven brain samples from AIDS patients. Viral sequences were identified in the specimens derived either from the grey (frontal cortex and basal ganglia) or from the periventricular white matter. HHV-6 DNA was found only in 6 of the 37 primary brain tumor biopsies examined. This study provides for the first time molecular evidence of a wide distribution of HHV-6 infection in the brain tissues of a high proportion of subjects, both in normal and in impaired immunity. In this large series of tumor biopsies the presence of HHV-6 genomic sequences is a rare phenomenon, arguing against a major role of this herpesvirus in the pathogenesis of primary brain tumors of neuroglial origin in immunocompetent subjects.
Decoupling of reactions in reactive polymer blending for nanoscale morphology control (2012)

Abstract In this study, a dynamic vulcanized alloy of brominated poly(isobutylene‐ co‐p ‐methylstyrene) (BIMSM) and polyamide (PA) has been investigated. An interfacial reaction between BIMSM and PA and a crosslinking reaction between BIMSM molecules is carried out simultaneously during melt blending. To form a vulcanized, nanoscale elastomer dispersion, the timing of these reactions is key and the interfacial reaction should be well advanced before the vulcanization reaction initiates. At a blending temperature of 205 °C, independent of the processing conditions, it is found that the interfacial reaction dominates the phase morphology development. Increasing the melt processing temperature, however, begins to favor the vulcanization reaction over the interfacial reaction. In nonplasticized blends, it is found that increasing the temperature above 235 °C increases the speed of the vulcanization reaction to a level that it dominates the phase morphology development. As a result, the phase size increases by 2.5‐fold because the system is vulcanized before the interfacial modification step is complete. Adding plasticizer to the PA matrix increases the overall phase size, but shows a similar behavior with increase in temperature from 205 to 255 °C. The critical temperature where the vulcanization reaction starts dominating phase morphology in the plasticized systems is at 225 °C. Once the processing temperature is above the critical temperature, it is found that the mixing sequence can be used to time and decouple the reactions. The work demonstrates that a close control over the temperature and processing conditions can be used to decouple the interfacial and vulcanization reactions resulting in vulcanized, nanoscale dispersions for the BIMSM and PA system. © 2012 Wiley Periodicals, Inc.

Insecticide Resistance in Two <I>Aedes aegypti</I> (Diptera: Culicidae) Strains From Costa Rica (2013)

Dengue (family Flaviridae, genus Flavivirus, DENV) and dengue hemorrhagic fever (DHF) are presently important public health problems in Costa Rica. The primary strategy for disease control is based on reducing population densities of the main mosquito vector Aedes aegypti (L.) (Diptera: Culicidae). This is heavily dependent on use of chemical insecticides, thus the development of resistance is a frequent threat to control program effectiveness. The objective of this study was to determine the levels of insecticide resistance and the metabolic resistance mechanisms involved in two Ae. aegypti strains collected from two provinces (Puntarenas and Limon) in Costa Rica. Bioassays with larvae were performed according to World Health Organization guidelines and resistance in adults was measured through standard bottle assays. The activities of beta-esterases, cytochrome P450 monooxygenases, and glutathione S-transferases (GST), were assayed through synergists and biochemical tests, wherein the threshold criteria for each enzyme was established using the susceptible Rockefeller strain. The results showed higher resistance levels to the organophosphate (OP) temephos and the pyrethroid deltamethrin in larvae. The efficacy of commercial formulations of temephos in controlling Ae. aegypti populations was 100% mortality up to 11 and 12 d posttreatment with daily water replacements in test containers. Temephos and deltamethrin resistance in larvae were associated with high esterase activity, but not to cytochrome P450 monooxygenase or GST activities. Adult mosquitoes were resistant to deltamethrin, and susceptible to bendiocarb, chlorpyrifos, and cypermethrin. Because temephos and deltamethrin resistance are emerging at the studied sites, alternative insecticides should be considered. The insecticides chlorpyrifos and cypermethrin could be good candidates to use as alternatives for Ae. aegypti control.
<title>Spaceguard-1: a space-based observatory for NEO physical characterization and discovery</title> (2000)

We investigate a broad system design for a space-based observatory operating at mid-infrared and visible wavelengths to perform physical characterization and discovery of near-Earth objects (NEOs) in the inner solar system. Our goals require measurements that are much more efficiently done from space. The mission objectives are to obtain accurate diameters, albedos and multiband reflectance properties for the known NEOs, and to conduct a search for objects spending most or all their orbital period inside Earth's orbit. The purpose is to observe a large fraction of the existing population during a mission operational lifetime of two years. A rather modest sized telescope (70 cm primary mirror and Ritchey-Chretien optical configuration) is found to be adequate to meet the objectives.
Selective Fusion of Azurophilic Granules with Leishmania-containing Phagosomes in Human Neutrophils (2010)

Leishmania parasites use polymorphonuclear neutrophils as intermediate hosts before their ultimate delivery to macrophages following engulfment of parasite-infected neutrophils. This leads to a silent and unrecognized entry of Leishmania into the macrophage host cell. Neutrophil function depends on its cytoplasmic granules, but their mobilization and role in how Leishmania parasites evade intracellular killing in neutrophils remain undetermined. Here, we have found by ultrastructural approaches that neutrophils ingested Leishmania major promastigotes, and azurophilic granules fused in a preferential way with parasite-containing phagosomes, without promoting parasite killing. Azurophilic granules, identified by the granule marker myeloperoxidase, also fused with Leishmania donovani-engulfed vacuoles in human neutrophils. In addition, the azurophilic membrane marker CD63 was also detected in the vacuole surrounding the parasite, and in the fusion of azurophilic granules with the parasite-engulfed phagosome. Tertiary and specific granules, involved in vacuole acidification and superoxide anion generation, hardly fused with Leishmania-containing phagosomes. L. major interaction with neutrophils did not elicit production of reactive oxygen species or mobilization of tertiary and specific granules. By using immunogold electron microscopy approaches in the engulfment of L. major and L. donovani by human neutrophils, we did not find a significant contribution of endoplasmic reticulum to the formation of Leishmania-containing vacuoles. Live Leishmania parasites were required to be optimally internalized by neutrophils. Our data suggest that Leishmania promastigotes modulate their uptake by neutrophils, and regulate granule fusion processes in a rather selective way to favor parasite survival in human neutrophils.
The estimation of some different kinds of human haemoglobin (1955)

Abstract The estimation of the amount of abnormal haemoglobins in the blood (in this case the foetal and sickle cell haemoglobin) can be carried out by different methods. It will be outlined that only by combination of some of these methods it is possible to detect the presence of small amounts of the foetal haemoglobin.

Invasive Non- <i>Aspergillus</i> Mold Infections in Transplant Recipients, United States, 2001–2006 (2011)

Recent reports describe increasing incidence of non-Aspergillus mold infections in hematopoietic cell transplant (HCT) and solid organ transplant (SOT) recipients. To investigate the epidemiology of infections with Mucorales, Fusarium spp., and Scedosporium spp. molds, we analyzed data from the Transplant-Associated Infection Surveillance Network, 23 transplant centers that conducted prospective surveillance for invasive fungal infections during 2001-2006. We identified 169 infections (105 Mucorales, 37 Fusarium spp., and 27 Scedosporium spp.) in 169 patients; 124 (73.4%) were in HCT recipients, and 45 (26.6%) were in SOT recipients. The crude 90-day mortality rate was 56.6%. The 12-month mucormycosis cumulative incidence was 0.29% for HCT and 0.07% for SOT. Mucormycosis incidence among HCT recipients varied widely, from 0.08% to 0.69%, with higher incidence in cohorts receiving transplants during 2003 and 2004. Non-Aspergillus mold infections continue to be associated with high mortality rates. The incidence of mucormycosis in HCT recipients increased substantially during the surveillance period.

Factors affecting water quality in the releases from hydropower reservoirs (1990)

Typical water quality concerns with releases from hydropower reservoirs include low dissolved oxygen, inappropriate temperature for downstream uses, supersaturation of total dissolved gases, and water quality constituents associated with low dissolved oxygen. Except for supersaturation of total dissolved gases, which is usually caused by by-passing turbines and spilling water, all of these concerns are related to the limnology of the upstream reservoir. Various limnological factors affect water quality, particularly dissolved oxygen (DO) in turbine releases. This paper describes three groups of reservoirs, thermal stratification characteristics for each group, DO effects for each group, the main factors that affect DO in TVA turbine releases, and other water quality constituents that are related to low DO.
Practical Control Design for a Power Supply with Saturable Magnetics (2006)

This study presents a control design procedure useful for power supplies featuring saturable magnetics. The paper addresses load identification, analysis limitations, and experimental evaluation. The system is described by a nonlinear state-space representation that is converted to a linearized time-varying system, which in turn is sampled to provide a discrete-time representation. We discuss some continuous versus discrete-time issues. Power supplies based on the ferroresonant transformer have been reported to be incompatible with loads that feature negative input resistance such as certain power factor corrected loads. This often causes instability in the controlled variable. The study proposes a procedure that leads to a feedback controller that stabilizes such systems. The suggested method is expected to be useful for ferroresonant power supplies and load interaction studies. This type of power supply is frequently encountered in telecommunication applications.
Comparison of oxygen consumption in rats during uphill (concentric) and downhill (eccentric) treadmill exercise tests. (2014)

The study of the physiological adaptations of skeletal muscle in response to eccentric (ECC) contraction is based on protocols in which exercise intensities are determined relative to the concentric (CON) reference exercise (as percentage of the CON maximal oxygen consumption, or VO2max). In order to use similar exercise protocols in rats, we compared the VO2 values during uphill (CON) and downhill (ECC) running tests. VO2 was measured in 15 Wistar rats during incremental treadmill running exercises with different slopes: level (0%), positive (+15% incline: CON+15%) and negative (i15% incline: ECC-15%; and 130% incline: ECC-30%). Similar VO2 values were obtained in the ECC-30% and CON+15% running conditions at the three target speeds (15, 25 and 35 cm/sec). Conversely, VO2 values were lower (p < 0.05) in the ECC-15% than in the CON+15% condition (CON+15% VO2/ECC-15% VO2 ratios ranging from 1.86 to 2.05 at the three target speeds). Thus, doubling the downhill slope gradient in ECC condition leads to an oxygen consumption level that is not significantly different as in CON condition. These findings can be useful for designing animal research protocols to study the effects of ECC and CON exercise in ageing population or subjects suffering from cardiovascular diseases. Key PointsVO2 in rats during treadmill race in eccentric and concentric conditions were measured.A novel breath-by-breath device allowing direct access to the animal was used.THREE DIFFERENT SLOPES: +15%, -15% and -30% were used.VO2 values obtained in the -30% eccentric and the +15% concentric conditions were not significantly different.
