Silica Films Having Zigzag Mesoporous Structures with Fixed Kink Angles (2007)

Mesoporous silica films with a highly controlled unique zigzag porous structure are prepared on a rubbing-treated polyimide film. The honeycomb-packed tubular pores in the films have two distinct in-plane alignment directions with respect to the rubbing direction; that is, the films have an in-plane zigzag mesoporous structure with a fixed kink angle. The kink angle is controllable by the molar ratio of tetraethoxysilane as a silica source to surfactant in the reactant solution, and the increase of the ratio results in larger kink angles. The zigzag structure is found to be formed through the formation of an initial immature mesostructured film with uniaxially aligned rodlike surfactant assemblies. It is highly probable that the observed in-plane bending of the pores is caused by the translational shift of the positions of the adsorbed surfactant molecules along the polyimide chains on the surface and that the shift is caused by the steric effects between the adjacent hydrophilic components consisting of surfactant head groups and silica oligomers. The present results show that a unique nanoscale structure, which can hardly be obtained through a reaction under homogeneous conditions, can be formed under the heterogeneous conditions in which the reaction takes place within a restricted environment.
Role of endothelin in the cardiovascular effects of diaspirin crosslinked and stroma reduced hemoglobin (1996)

The endothelin-A receptor antagonist, BQ-123, could attenuate the systemic hemodynamic and regional circulatory effects of diaspirin crosslinked hemoglobin and stroma reduced hemoglobin. However, the increase in blood flow to the heart induced by stroma reduced hemoglobin could not be attenuated by BQ-123.
Chloroplast phylogenomic analysis of chlorophyte green algae identifies a novel lineage sister to the Sphaeropleales (Chlorophyceae) (2015)

Our phylogenomic study advances our knowledge regarding the circumscription and internal structure of the Chlamydomonadales, suggesting that a previously unrecognized lineage is sister to the Sphaeropleales. In addition, it offers new insights into the flagellar structures of the founding members of both the Chlamydomonadales and Sphaeropleales.
Electronic Transport of Encapsulated Graphene and WSe2 Devices Fabricated by Pick-up of Prepatterned hBN (2015)

We report high quality graphene and WSe2 devices encapsulated between two hexagonal boron nitride (hBN) flakes using a pick-up method with etched hBN flakes. Picking up prepatterned hBN flakes to be used as a gate dielectric or mask for other 2D materials opens new possibilities for the design and fabrication of 2D heterostructures. In this Letter, we demonstrate this technique in two ways: first, a dual-gated graphene device that is encapsulated between an hBN substrate and prepatterned hBN strips. The conductance of the graphene device shows pronounced Fabry-Pérot oscillations as a function of carrier density, which implies strong quantum confinement and ballistic transport in the locally gated region. Second, we describe a WSe2 device encapsulated in hBN with the top hBN patterned as a mask for the channel of a Hall bar. Ionic liquid selectively tunes the carrier density of the contact region of the device, while the hBN mask allows independent tunability of the contact region for low contact resistance. Hall mobility larger than 600 cm(2)/(V·s) for few-layer p-type WSe2 at 220 K is measured, the highest mobility of a thin WSe2 device reported to date. The observations of ballistic transport in graphene and high mobility in WSe2 confirm pick-up of prepatterned hBN as a versatile technique to fabricate ultraclean devices with high quality contact.
Die BTÖV-Methode - Vorgehensweise und Ziele bei der bedarfsgerechten Gestaltung von Telekooperation in der öffentlichen Verwaltung (1995)

Dieser Beitrag stellt eine Methode zur bedarfsgerechten Gestaltung der Telekooperation vor. Unserer Meinung nach kommt es bei der Gestaltung der Telekooperation insbesondere auf die integrierte Betrachtung von ‘weichen’ Faktoren (aus der betrieblichen Organisationslehre und Personalwirtschaft) und ‘harten’ Faktoren (Software-Engineering und Wirtschaftlichkeitskriterien) an. Das Projekt BTÖV (= Bedarf für Telekooperation in der öffentlichen Verwaltung) hat sich zum Ziel gesetzt, eine solche integrierte Methode für die Gestaltung der Telekooperation in der öffentlichen Verwaltung zu entwerfen und zu evaluieren, die sich am Bedarf der Nutzer orientiert und genauso flexibel und schnell änderbar ist, wie ihr Anwendungsgebiet. Es werden zunächst Ausgangspunkt, Konzept und die Ziele des BTÖV-Projekts erläutert. Daran anschließend wird ein Überblick über die Vorgehensweise und Charakteristika der ”BTÖV-Methode” gegeben. Ein Ausblick auf die Weiterentwicklung der BTÖV-Methode schließt den Artikel.
[Neurologic manifestations of ciguatera. 3 cases with a neurophysiologic study and examination of one nerve biopsy]. (1986)

Ciguatera is the commonest form of poisoning resulting from eating fish in the tropics. It has been recognised since the 15th century. The disease is due to the formation of ciguatoxin by a dinoflagellate, Gambierdiscus toxicus, loosely attached to algae growing on coral reefs. The toxin, which is harmless to the fish, is ingested by small herbivorous fish and passes up the food chain as these are eaten by carnivores. The toxic effects include gastroenteritis, itching of the skin, peripheral neuropathy and central nervous system dysfunction. Though most cases are mild, occasionally the disease is severe and even fatal. There is no effective specific treatment. Three cases, of which one died and which exhibited both peripheral and central nervous system involvement, are described. Histological changes in sural nerve fibers are described. There was striking oedema of the adaxonal Schwann cell cytoplasm. These histological changes are very similar to those seen following the injection of scorpion and spider venoms into the peripheral nerve of experimental animals. Both these venoms and ciguatoxin increase the permeability of the membrane to sodium.

Fertilizer placement for cereal root access (1983)

Conservation tillage, which involves surface crop residue ( 16 ), often results in seedbed and near-surface soil environments that are not always as suitable as they might be for growth of cereal grain seedlings ( 25 ). Microbial decomposition of surface residue or partially incorporated residue immobilizes mineral nutrients, particularly nitrogen. Competition for these nutrients in early spring limits the supply available for uptake by plant roots ( 1, 3 ). Without incorporation of fertilizer, rain or irrigation is required to move mobile nutrients down into the root zone. Immobile nutrients are not accessible unless they are physically placed where roots can grow to them. Spring crops grow most rapidly when they have access to nutrients immediately following emergence. Delayed access may limit early seedling growth and reduce grain yields.

Placing fertilizer deep in the soil usually offsets the immobilization effects some, but proper location is important for maximum root access by young plants. Small amounts of starter fertilizer can be banded with the seed. Applying the entire crop requirement. However, may delay or stop seed development ( 2, 6, 12, 15, 17 ).

Fertilizers can be banded deep in the soil either prior to planting or in the interrow zone at planting time. But either method …
Identification of New Presenilin Gene Mutations in Early-Onset Familial Alzheimer Disease (2003)

One novel PS2 mutation associated with highly penetrant but variable age at onset (35-85 years) and 2 novel PS1 missense mutations associated with early-onset Alzheimer disease at age 49 to 54 years have been identified in Italian families. Screening for new mutations in presenilin and betaAPP genes was beneficial in characterizing gene function in FAD.
Production, use, and upgrading of natural gas in Argentina (2002)

This work briefly reviews the economic, energetic, industrial, and environmental roles that natural gas plays nowadays in Argentina. The evolution of natural gas production and consumption in Argentina over the last decades is analyzed and compared with other Latinamerican countries. The use of natural gas as ground transportation fuel is presented, taken into account that about 7% of the Argentine vehicle fleet are composed of natural gas fueled vehicles. The role of catalytic technologies for transforming natural gas into cleaner fuels and valuable chemicals is also discuss.
Implementing SARS-CoV-2 Rapid Antigen Testing in the Emergency Ward of a Swiss University Hospital: The INCREASE Study (2021)

Following the Swiss Federal Office of Public Health (FOPH) authorization of the rapid antigen test (RAT), we implemented the use of the RAT in the emergency ward of our university hospital for patients' cohorting. RAT triaging in association with RT-PCR allowed us to promptly isolate positive patients and save resources. Among 532 patients, overall sensitivities were 48.3% for Exdia and 41.2% for Standard Q<sup>®</sup>, Panbio<sup>TM</sup> and BD Veritor™. All RATs exhibited specificity above 99%. Sensitivity increased to 74.6%, 66.2%, 66.2% and 64.8% for Exdia, Standard Q<sup>®</sup>, Panbio<sup>TM</sup> and BD Veritor™, respectively, for viral loads above 10<sup>5</sup> copies/mL, to 100%, 97.8%, 96.6% and 95.6% for viral loads above 10<sup>6</sup> copies/mL and 100% for viral loads above 10<sup>7</sup> copies/mL. Sensitivity was significantly higher for patients with symptoms onset within four days (74.3%, 69.2%, 69.2% and 64%, respectively) versus patients with the evolution of symptoms longer than four days (36.8%, 21.1%, 21.1% and 23.7%, respectively). Among COVID-19 asymptomatic patients, sensitivity was 33%. All Immunoglobulin-A-positive patients resulted negative for RAT. The RAT might represent a useful resource in selected clinical settings as a complementary tool in RT-PCR for rapid patient triaging, but the lower sensitivity, especially in late presenters and COVID-19 asymptomatic subjects, must be taken into account.
A 60 GHz compact single-chip sub-harmonically pumped receiver MMIC (2007)

A 60 GHz compact single-chip sub-harmonically pumped receiver (RX) MMIC has been designed and characterized in a 0.15 mum, ~120 GHz f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T</sub> / >200 GHz f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">MAX</sub> GaAs mHEMT MMIC process. The single-chip multi-functional RX MMIC consists of a two-stage amplifier and a sub-harmonically pumped resistive mixer (SHPRM) with an ultra broadband active balun for the LO feed. The RX chip has a very flat frequency response and has only 0.3 dB of ripple between 60 and 65 GHz. A very broadband IF signal is possible with a 3 dB IF bandwidth of 6.8 GHz. The broadband IF is combined with a very good linearity, the input referred third order intercept point (IIP3) is as high as -5 dBm, making the receiver especially suitable for use in a homodync system, receiving data-rates of several Gbit/s. Those good results are obtained at a total DC power consumption as low as 154 mW.
Additive manufacturing of the ferritic stainless steel SS441 (2020)

In this study, the ferritic stainless steel SS441 was produced with excellent mechanical properties using laser powder bed fusion (L-PBF) compared to samples produced by conventional casting and hot-rolling. In addition, thermodynamic calculations were utilized to study the phase stability at elevated temperatures and to understand the solidification behavior. The hot-rolled sample showed a grain size up to several hundred μm with additional precipitates of TiN and Nb(C,N). In contrast, the as-built L-PBF samples displayed a grain size in the μm range. Spherical precipitates with a size of around 50 nm could be observed and were attributed to a corundum phase from the thermodynamic calculations. The printed material shows superior mechanical properties, with more than 30 times higher impact energy compared to the hot-rolled alloy (217 ± 5 J vs. 7 ± 0.5 J). Furthermore, the properties are anisotropic for the L-PBF produced alloy, with the highest tensile strength vertical to the build direction. The superior mechanical properties of the L-PBF produced sample can be attributed to a smaller grain size, giving a higher strength according to the Hall-Petch relationship. The anisotropy of the material can be eliminated by heat treatments at 900 °C followed by water quenching, but the absolute strength decreases slightly due to formation of intermetallic phases such as Nb(C,N) and the Fe2Nb Laves phase. The results clearly illustrates that L-PBF provides a promising manufacturing route for enhanced strength of ferritic stainless steels.
Diseño, validación y evaluación de un programa educativo sobre bebidas alcohólicas, tabaco y marihuana (2017)

This research aims to design, validate and evaluate an educational program on alcoholic drinks, tobacco and marijuana, on highschool second year students at Liceo Bolivariano Andres Eloy Blanco, Merida, Venezuela, during the school year 2015-2016. The educational program was developed with eXe Learning software, and done under the significant learning theory, with exhibition - discussion instructional design. The approach of the investigation was quantitative, evaluative type, correlational scope, and quasi-experimental design. It was found that the educational program is valid, according to five judges. The educational program was more effective than
the traditional program since the students showed better grades. The variables sex, occupation of student representative, educational level of student representative, use of drugs of relatives, environment surrounding and use of mass media information did not influence the school grades of the students. It is recommended the permanent use of the education program as support of other educational materials, for the subjects to whom it was designed, to other formal levels, to the family and to the communal organizations.
Hydrocephalus Produced by the 6/94 Virus (1975)

The 6/94 virus, parainfluenza type 1 isolate from multiple sclerosis brain tissue, produced hydrocephalus in newborn Syrian hamsters. All animals developed clinical disease and died within a week. Ependymal cells lining the aqueduct of Sylvius became necrotic and fused, resulting in obstructive hydrocephalus. The 6/94 virus antigen was seen in ependyma and meninges. Paramyxovirus nucleocapsids were seen within cytoplasm of ependymal cells. Virus was recovered from hamster brains for only two days. Infectious virus could be recovered from brains grown in vitro as explants for 21 days. No evidence of rising hemagglutination-inhibiting antibody was noted for up to one month after infection. Intraperitoneal or subcutaneous injection of 6/94 virus did not produce hydrocephalus. HA2 virus and the temperature sensitive mutant of HA2 virus failed to produce hydrocephalus, while Sendai virus caused lesions similar to those of 6/94 virus.
Residential energy scheduling for variable weather solar energy based on adaptive dynamic programming (2017)

The residential energy scheduling of solar energy is an important research area of smart grid. On the demand side, factors such as household loads, storage batteries, the outside public utility grid and renewable energy resources, are combined together as a nonlinear, time-varying, indefinite and complex system, which is difficult to manage or optimize. Many nations have already applied the residential real-time pricing to balance the burden on their grid. In order to enhance electricity efficiency of the residential micro grid, this paper presents an action dependent heuristic dynamic programming (ADHDP) method to solve the residential energy scheduling problem. The highlights of this paper are listed below. First, the weather-type classification is adopted to establish three types of programming models based on the features of the solar energy. In addition, the priorities of different energy resources are set to reduce the loss of electrical energy transmissions. Second, three ADHDP-based neural networks, which can update themselves during applications, are designed to manage the flows of electricity. Third, simulation results show that the proposed scheduling method has effectively reduced the total electricity cost and improved load balancing process. The comparison with the particle swarm optimization algorithm further proves that the present method has a promising effect on energy management to save cost.
Proposal for a joint library mechanization and text processing project (1971)

Scope of the ProjectIn 1968, the CERN Library started to develop a mechanized catalogue of preprints and reports based on a weekly accessions list to which indexes by personal authors, collaboration groups, corporate authors, report numbers, conferences and subject descriptors are provided.This system uses a Flexowriter for typing the accessions list and a computer only for producing the indexes.Since the introduction of this mechanized catalogue, the need for more satellite libraries and dissemination of bibliographic information on the extended CERN site has become apparent.National and international specialized information centres have recently started the interchange of bibliographic information on magnetic tape, a new development from which CERN may take great advantage.The time seems to have come therefore, to review the present library operation and to study possible improvement.A proposal for the development of a mechanized library system is made in chapter 2 of this report.
Unified robust zero-error tracking control of CVCF PWM converters (2002)

This paper proposes a unified robust zero-error tracking control scheme for constant-voltage-constant-frequency (CVCF) PWM converters to eliminate the tracking error in the presence. Based on the internal model principle, the proposed control scheme plugs a reference signal generator into the stable conventional feedback closed-loop system to accomplish zero error tracking of the dc or ac reference input. The design of the unified zero error tracking controller is systematically developed and the stability analysis of overall control system is discussed. Three examples of the proposed controlled CVCF converters, such as CVCF PWM inverter, boost-type PWM rectifier, and dc-dc PWM buck converter are studied to testify the validity of the proposed approach. Simulation and experimental results demonstrate satisfactory performance of the proposed unified robust zero error tracking controller even under parameter uncertainties and load disturbances.
Clinical and structural insights into potential dominant negative triggers of proximal urea cycle disorders (2020)

Despite biochemical and genetic testing being the golden standards for identification of proximal urea cycle disorders (UCDs), genotype-phenotype correlations are often unclear. Co-occurring partial defects affecting more than one gene have not been demonstrated so far in proximal UCDs. Here, we analyzed the mutational spectrum of 557 suspected proximal UCD individuals. We probed oligomerizing forms of NAGS, CPS1 and OTC, and evaluated the surface exposure of residues mutated in heterozygously affected individuals. BN-PAGE and gel-filtration chromatography were employed to discover protein-protein interactions within recombinant enzymes. From a total of 281 confirmed patients, only 15 were identified as "heterozygous-only" candidates (i.e. single defective allele). Within these cases, the only missense variants to potentially qualify as dominant negative triggers were CPS1 p.Gly401Arg and NAGS p.Thr181Ala and p.Tyr512Cys, as assessed by residue oligomerization capacity and surface exposure. However, all three candidates seem to participate in critical intramolecular functions, thus, unlikely to facilitate protein-protein interactions. This interpretation is further supported by BN-PAGE and gel-filtration analyses revealing no multiprotein proximal urea cycle complex formation. Collectively, genetic analysis, structural considerations and in vitro experiments point against a prominent role of dominant negative effects in human proximal UCDs.
Defect-enhanced electron field emission from chemical vapor deposited diamond (1995)

Diamond samples with varying defect densities have been synthesized by chemical vapor deposition, and their field emission characteristics have been investigated. Vacuum electron field emission measurements indicate that the threshold electric field required to generate sufficient emission current densities for flat panel display applications (≳10 mA/cm2) can be significantly reduced when the diamond is grown so as to contain a substantial number of structural defects. The defective diamond has a Raman spectrum with a broadened peak at 1332 cm−1 with a full width at half maximum (FWHM) of 7–11 cm−1. We establish a strong correlation between the field required for emission and the FWHM of the diamond peak. The threshold fields are typically less than 50 V/μm and can reach as low as 30 V/μm for diamond with a FWHM greater than 8.5 cm−1. It is believed that the defects create additional energy bands within the band gap of diamond and thus contribute electrons for emission at low electric fields.
