Is Normoreninemic Essential Hypertension Caused by Disordered Central Dopaminergic Regulation? (1980)

Some investigators have reported that plasma prolactin levels are elevated in hypertensive men and that both their hyperprolactinemia and hypertension were controlled by bromocriptine, a dopamine agonist. They concluded that reduced central dopaminergic activity may be a factor in maintaining essential hypertension. We examined the serum prolactin and thyrotropin (TSH) responses to thyrotropin releasing hormone (TRH), metoclopramide (a dopamine antagonist) and bromocriptine in 10 normal and 10 hypertensive normoreninemic men. TRH caused significant increase of both prolactin and TSH and metoclopramide caused significant increase of prolactin in both normals and hypertensives. Bromocriptine suppressed prolactin and TSH significantly in both groups. There were no significant differences in prolactin and TSH levels between the normal and hypertensive groups before or during the tests. These results provide no support for the hypothesis that alterations in the activity of central dopaminergic neurons are involved in the maintenance of the elevated blood pressure of normoreninemic men with essential hypertension.
Computational Design of Infrared Enhanced Layering of ICF Capsules (2004)

A computational model is presented for infrared heating of frozen hydrogen layers in cryogenic ICF capsules. The model contains linked ray trace and heat conduction programs. The conduction part of the model has been validated with a cryogenic hohlraum experiment without infrared irradiation. The complete model has been used to design and analyze experiments on infrared layering of D2 in a hohlraum. The modeling provides an understanding of how to control the long scale length ice thickness perturbations by varying the infrared power balance and beam pointing. Based on the confidence developed in the model by comparison to experiment, design calculations are presented for IR layering systems for ICF ignition targets.
High surface and magnetically recoverable mPANI/pFe<sub>3</sub>O<sub>4</sub>nanocomposites for C–S bond formation in water (2012)

A high surface area mPANI/pFe3O4 nanocomposite from mesoporous polyaniline and porous magnetic Fe3O4 was used as a catalyst in the S-arylation of thiophenol with aryl chlorides and in the C–S bond formation between aryl iodides and thiourea in water. The mesoporosity of the polyaniline enhances the efficiency and stability of the porous magnetic Fe3O4 nanoparticles in both coupling reactions. The mPANI/pFe3O4 nanocomposite can be recovered with an external magnet and reused several times due to the superparamagnetic nature of the porous Fe3O4 nanoparticles.
Doing it Right or Doing the Right it? Uncertainty, Innovation, and Group Composition (2005)

Though theoretical links have been established between group diversity and performance on creative tasks, researchers have had difficulties confirming this view. In this inductive study we argue that part of this difficulty stems from a failure to fully account for the effects of uncertainty on task performance groups. Using qualitative and quantitative data from an RD and, therefore, has a direct effect on task and relational processes in the group. We suggest that the value in diversity for a group is likely to decrease as uncertainty increases, and that only relatively bounded and certain tasks (in particular brainstorming and other forms of creative problem solving) are likely to derive the benefits associated with compositional diversity in groups.
Isomeric identification by laser control mass spectrometry (2006)

The influence shaped femtosecond laser pulses have on molecular photofragmentation and ionization, coupled with the intrinsic sensitivity of mass spectrometry, results in a powerful tool for fast, accurate, reproducible and quantitative isomeric identification. Complex phase functions are introduced to enhance differences during the laser-molecule interactions, which depend on geometric structure, resulting in different fragmentation fingerprints. A full account is given on the setup and results leading to a technique that can be used to distinguish between compounds normally indistinguishable by conventional electron ionization mass spectrometry. We demonstrate geometric and structural isomer identification of cis-/trans-3-heptene, cis-/trans-4-methyl-2-pentene, o-/p-cresol and o-/p-xylene. For the positional isomers of xylene we present a complete dataset consisting of 1024 different phases to explore phase complexity. A selection of two phases from that data can then be used to achieve quantitative identification in mixtures of xylene isomers. Finally, we evaluate receiver operational curves obtained from our experimental data to demonstrate the reliability that can be achieved by femtosecond laser control mass spectrometry.
Phase II study of cis-dichlorodiammineplatinum(II) in advanced breast cancer. (1978)

Twenty-six patients with metastatic breast cancer received cis-dichlorodiammineplatinum(II) either as a single dose of 100 mg/m2 iv every 3--4 weeks or as a continuous 5-day infusion of 20 mg/m2/day at 4-week intervals. Fourteen patients were treated with the single-dose schedule and 12 patients were treated with the continuous 5-day infusion. No significant response was observed with either dose schedule. Aside from a reduction in the frequency and severity of gastrointestinal toxicity with the continuous 5-day infusion, no real difference was seen with regard to renal and hematologic toxicity with either dose schedule.
X.—<i>The St. Albans School of Painting, Mural and Miniature: Part I. Mural Painting</i> (1902)

The history of mural and panel painting in England before the sixteenth century may perhaps be divided into three periods. Firstly, that from the Norman Conquest, or possibly before, which continued during the wave of monastic enthusiasm which swept over Europe, and ended at the close of the thirteenth century. During this time there is every reason to suppose from the evidence of chronicles, fabric rolls, and works accounts that in England as well as elsewhere all the decorative arts were practised by persons associated together in schools or lodges with three gradations of members, namely, masters, workmen, and apprentices or novices. Art was at this date fostered by the monasteries, indeed, those who practised it were largely drawn from the inmates of the Benedictine houses, and it would seem that, at all events at St. Albans, the sacrists were themselves workers and sometimes held the rank of master workmen. During this period one man practised many arts. We know that Richard the Painter superintended the building of Hereford Castle in 1172, and, later, Master John of St. Omer, while making the great lectern for the chapter house at Westminster in 1253, had carpenters, masons, painters, smiths, and others working under his direction. Numerous other instances could be quoted were not the practice so well known as to make it unnecessary.

Development Non-Contact, Non-Destructive Evaluation for Concrete Structures by Using Shock Wave and Study of Its Automation (2004)

We developed a basic technology of non-contact, non-destructive inspection method of a concrete structure. It is a current inspection approach that an operator beats surface of a wall with a hammer and hears the sound with his ears, and judges the presence of the defect. The purposes of this study are the improvement of reliability and the curtailment of expenses by the automation of evaluation. The proposed method of this study is that the impact by hammer is replaced with shock wave and the safety check by operator's ears is replaced with the laser measurement. We did a simulation using a finite element method and succeeded detection of a defect of 25 mm diameter and in 200 mm depth. The method of this study is a technology to enable that we inspect concrete structures by non-contact, non-destructive test automatically.
Intramolecular Charge Transfer, Studied by Electrochromism of Organic Molecules in Polymer Matrices (1979)

Abstract The ground state dipole moment. , and the change in dipole moment upon excitation, , of various dyes have been determined from electrochromic measurements on solutions in polymer matrices. The merits of this method are discussed. High values of , much in excess of the sum of local group moments, are found for compounds in which a polar ground state is stabilized by large differences in electronegativity of the constituting groups (“Zwitterions”) and/or by a gain in resonance energy accompanying a charge transfer in π-electron ring systems. High values of , indicating a large charge transfer upon excitation, are connected with a loss of resonance energy. The amount of charge, transferred upon excitation from the donor group of the dye to the acceptor group, does not decrease significantly if the geometric distance between these groups is increased by inserting enthynylenic groups.
Recommended Practice for Pressure Measurements and Calculation of Effective Pumping Speeds During Electric Propulsion Testing (2013)

The electric propulsion community has been implored to establish and implement a set of universally applicable test standards during the research, development, and qualification of electric propulsion systems. Variability between facility-to-facility and more importantly ground-to-flight performance can result in large margins in application or aversion to mission infusion. Performance measurements and life testing under appropriate conditions can be costly and lengthy. Measurement practices must be consistent, accurate, and repeatable. Additionally, the measurements must be universally transportable across facilities throughout the development, qualification, spacecraft integration, and on-orbit performance. A recommended practice for making pressure measurements, pressure diagnostics, and calculating effective pumping speeds with justification is presented.
Local Factorization of Functions (2003)

This paper is concerned with the notion of a local factorization of a function where we are mostly interested in the special case that this function is a probability distribution. We introduce the notions of local independence and of the local Kullback-Leibler divergence. We introduce a specific approximate local factorization. The number of terms required in the approximation is linear in the number of input dimensions and the approximation does not require the calculation of higher derivatives (as in a Taylor expansion) and is not limited to approximations near the mode of a function. We provide examples where we believe the approximation might be useful as in the approximate calculation of certain integrals.

Synthesis and structural characterization of a heterocomposition based on porous layers of SiC polytypes (2004)

We have studied the structure of transverse cross sections of a heterocomposition consisting of porous layers of silicon carbide polytypes (substrate 6H-SiC/por-6H-SiC/epi-3C-SiC/por-3C-SiC). The epitaxial layer of 3C-SiC polytype (epi-3C-SiC) was grown by sublimation in vacuum on the surface of a porous 6H-SiC sublayer (por-6H-SiC) obtained by electrochemical etching of a 6H-SiC substrate. The boundary between the 3C-SiC epilayer and the porous 6H-SiC sublayer contains no defective transition layer, and the 3C-SiC epilayer is free of dislocations.
Pathogenic Variability of <i>Meloidogyne incognita</i> Populations Occurring in Pepper-Production Greenhouses in Israel Toward <i>Me1</i>, <i>Me3</i> and <i>N</i> Pepper Resistance Genes (2017)

Natural variation in the root-knot nematode Meloidogyne incognita is problematic for breeding programs: populations possessing similar morphological characteristics can produce different reactions on the same host. We collected 30 widely dispersed M. incognita populations from protected pepper production systems in major pepper-growing regions of Israel and accurately identified their virulence characteristics by modified differential host test in a growth chamber on tomato, tobacco, cotton, melon, pepper, and peanut. Galling indices and reproduction were determined on the different hosts. All populations fit the published scheme for M. incognita race 2, except for reproduction on cotton plants by five out of 25 tested M. incognita populations, indicating host-range variations. Reaction of three genes that confer resistance to M. incognita-Me1, Me3 and N-to the collected populations was evaluated. Several M. incognita populations induced galling and reproduced successfully on pepper genotypes carrying Me3 and N, whereas plant resistance conferred by Me1 was more robust for all examined populations. Moreover, the effect of genetic background on Me1 resistance demonstrated a relative advantage of several genotypes in nematode infestations. Efficiency of Me3 under local nematode infestation was further studied with a homozygous line carrying two Me3 alleles. Reproduction of virulent populations on the homozygotes (Me3/Me3) and heterozygotes (Me3/Me3<sup>+</sup>) was similar, suggesting a limited quantitative effect of Me3. These results present the first characterization of host range, reproduction, and molecular aspects of M. incognita from Israel and highlight the importance of taking a multidimensional approach in pepper-breeding programs for resistance to M. incognita.
DEVELOPMENT OF PUMP COMPONENTS FOR THE PRATT AND WHITNEY AIRCRAFT LIQUID METAL TURBOPUMP, TP-1 (1960)

The tests conducted on TP-l turbopump componerts consisted of mixed flow impeller tests, full scale TP-1 impeller and scroll-matching tests in water, cold hydrostatic tests of prototype TP-1 pump scroll, and evaluation of cermert type face seals. The water and hot liquid metal TP-l mechanical center section test units are described. Mechanical and hydraulic performance is estimated for the pump from the results of the component tests.

An Interconnection Network for a Cache Coherent System on FPGAs (2011)

Field-Programmable Gate Arrays (FPGAs) systems now comprise many processing elements that are processors running software and hardware engines used to accelerate specific functions. To make the programming of such a system simpler, it is easiest to think of a shared-memory environment, much like in current multi-core processor systems. This thesis introduces a novel, shared-memory, cache-coherent infrastructure for heterogeneous systems implemented on FPGAs that can then form the basis of a shared-memory programming model for heterogeneous systems. With simulation results, it is shown that the cache-coherent infrastructure outperforms the infrastructure of Woods [1] with a speedup of 1.10. The thesis explores the various configurations of the cache interconnection network and the benefit of the cache-to-cache cache line data transfer with its impact on main memory access. Finally, the thesis shows the cache-coherent infrastructure has very little overhead when using its cache coherence implementation.
Dependence of Impedance of Embedded Single Cells on Cellular Behaviour (2008)

Non-invasive single cell analyses are increasingly required for the medicaldiagnostics of test substances or the development of drugs and therapies on the single celllevel. For the non-invasive characterisation of cells, impedance spectroscopy whichprovides the frequency dependent electrical properties has been used. Recently,microfludic systems have been investigated to manipulate the single cells and tocharacterise the electrical properties of embedded cells. In this article, the impedance ofpartially embedded single cells dependent on the cellular behaviour was investigated byusing the microcapillary. An analytical equation was derived to relate the impedance ofembedded cells with respect to the morphological and physiological change ofextracellular interface. The capillary system with impedance measurement showed afeasibility to monitor the impedance change of embedded single cells caused bymorphological and physiological change of cell during the addition of DMSO. By fittingthe derived equation to the measured impedance of cell embedded at different negativepressure levels, it was able to extrapolate the equivalent gap and gap conductivity betweenthe cell and capillary wall representing the cellular behaviour.
Polymer Electrolyte Gate Dielectric Reveals Finite Windows of High Conductivity in Organic Thin Film Transistors at High Charge Carrier Densities (2005)

Finite regions of high conductivity were observed in both n- and p-channel organic thin film transistors based on polycrystalline organic semiconductor films and a solution-processed, solid polymer electrolyte gate dielectric. The transition from a highly conductive state to a more insulating state with increasing gate bias may be attributed to the realization of carrier densities greater than 1014 charges/cm2 in the semiconductor film.
Recycle hollow fiber enzyme reactor with flow swing (1985)

The hollow fiber enzyme reactor with pulsation developed by Kim and Chang (1983) was operated in a differential mode by recycling a substrate solution, in order to assess the efficiency of ultrafiltration swing. The rates of lactose conversion by beta-galactosidase contained in the shell side of the reactor were measured to determine the effects of recirculation rate, pulsation period, and amplitude. The conversion increased with the increase of recirculation flow rate and the amplitude while variation in period affected the conversion relatively little. The maximum increase of 113% in the activity was observed in the reactor with pulsation as compared to that without pulsation. The two-compartment model well described the experimental data obtained in this study. Square-wave pulsation was theoretically more effective in increasing conversion than sine wave pulsation. However, in experimental operation the damping effect of the hollow fiber wall narrowed the difference between these two wave forms.
Nouvelle approche stereoselective aux polyenes conjugues et composes polyinsatures (1995)

Nous avons tout d'abord etudie, en presence de pdcl#2(phcn)#2, la tres bonne reactivite des chloroenynes et chlorodienes fonctionnalises avec des alcynes terminaux, pour conduire stereospecifiquement, avec de tres bons rendements, a des enediynes et a des dienynes en un temps court (30 min a 1 h). Nous avons aussi decrit la substitution sequentielle stereospecifique en un pot des dichloroethylenes e et z pour conduire aux enediynes dissymetriques fonctionnalises e et z qui sont d'utiles intermediaires de synthese. Nous avons ensuite montre a travers quelques exemples appropries, que ces reactions de couplage permettent d'acceder pratiquement a n'importe quel isomere d'un polyene conjugue. On peut ainsi preparer des trienes, tetraenes, pentaenes, hexaenes, heptaenes de geometrie determinee. Ce procede stereo et chimioselectif a ete utilise pour realiser la synthese totale d'une molecule polyfonctionnelle: la lipoxine b. Notre approche synthetique conduit au systeme tetraenique (e,z,e,e) avec une grande purete isomerique et sans etape de protection-deprotection des fonctions alcools au cours de la synthese. Nous avons etudie la synthese de polyenes conjugues tout e. Nous avons, tout d'abord, decrit la semi-reduction stereoselective, par le red-al, des alcools homopropargyliques conjugues en alcools homoallyliques e conjugues. Nous avons ensuite montre que cette reaction de semi-reduction permet d'acceder aisement a des synthons (chlorures polyinsatures et polyenynes terminaux) utiles a la synthese de polyenes tout e. Nous avons montre que les chloroenynes e peuvent etre metalles par le n-buli pour conduire aux diynes, aux chloroenynes substitues et aux -chloro -halo enynes. Ces derniers sont de bons precurseurs de divers composes polyinsatures: chloro enediynes et enetriynes
Regulation of Central Cholecystokinin Recognition Sites by Guanyl Nucleotides (1988)

Guanyl nucleotides affected the binding of radiolabeled cholecystokinin (CCK) octapeptide to rodent cortical binding sites. Micromolar quantities of a stable GTP analogue, guanylyl-imidodiphosphate (GppNp), resulted in a plateau where binding was decreased by 30%. In the presence of 25 microM GppNp, binding analysis revealed a decrease in affinity (increase in KD), without an apparent effect on the maximal number of binding sites. Ki values for CCK-related peptides shifted up to 1.6-fold. The rate of peptide association decreased by threefold, and the rapid component of peptide dissociation increased. The collective data suggest that a class of central CCK binding sites is linked to nucleotide regulatory proteins. The evidence is discussed with regard to multiple receptor populations and to possible interconversions between receptor types.
Studies on the chemical modification of monensin. II. Measurement of sodium ion pemeability of monensylamino acids using sodium-23 nuclear magnetic resonance spectroscopy. (1989)

A technique to assay Na+ ions in cells is presented. Intracellular and extracellular Na+ ions in a suspension of guinea pig erythrocytes were conveniently determined by using sodium-23 nuclear magnetic resonance (23Na-NMR), in combination with two anionic shift reagents: Dy(TTHA)3- and Dy(PPPi)2(7-). Monensin (1), monensylalanine (2b), monensylserine (2c), and monensylphenylalanine (2d) induced large increases of intracellular Na+ ion concentration ([Nain]), while monensylglycine (2a), monensyltyrosine (2e), monensylaspartic acid (2f), and monensylglutamic acid (2g) showed slight increases. The values of initial increasing rate (Vi) of 2a-g were much smaller than that of 1. This fact was probably due to the lower lipophilicity of 2a-g than 1, because a good correlation was observed between Vi and Rm50 values of 1 and 2a-g. This lower lipophilicity is a consequence of conformational differences between 1 and 2a-g.
