The role of cations distribution on magnetic and reflection loss properties of ferrimagnetic SrFe12−x(Sn0.5Zn0.5)xO19 (2010)

The site preference and magnetic properties of Zn–Sn substituted strontium ferrite SrFe12−x(Sn0.5Zn0.5)xO19 particles with x=0–5 were studied using both F57e and S119n Mössbauer spectroscopies and magnetic measurements. The results show that the magnetization and magnetocrystalline anisotropy are closely related to the distributions of Zn–Sn ions on the five inequivalent crystal sites provided by the hexagonal structure of the ferrite. Mössbauer spectra show that the Zn–Sn ions preferentially occupy the 2b and 4f2 sites. The preference for these sites is responsible for the anomalous increase in the magnetization at low Zn–Sn substitutions. Based on microwave measurements of reflectivity, SrFe12−x(Sn0.5Zn0.5)xO19 is a good candidate for electromagnetic compatibility and other practical applications at high frequencies.
Bond wireless multichip packaging technology for high-speed circuits (1992)

A multichip packaging technology has been developed for use in the advanced hybrid integration of semiconductor chips made of different materials. The resulting multichip module (MCM) is similar to a monolithic circuit in that all the interconnects are made by photolithography and thin-film metallization. Any semiconductor chip can be integrated in this scheme without special chip metallization patterns or the incorporation of special features on the chips. In this technique, chips with backside contacts, such as laser diodes and photodetectors, can be packaged, offering greater flexibility and speed than other hybrid or multichip packaging technologies. Several different optoelectronic receivers which combine various GaAs, Si, and GaInAs chips have been successfully integrated and operated at frequencies ranging from 100 MHz to above 1 GHz.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Difference in thermal stability of type-I and type-III collagen from rat skin (1982)

Type-I and type-III collagens were obtained by differential salt fractionation of neutral-salt-soluble collagen from rat skin. Their thermal stabilities were determined by u.v. difference spectroscopy. The ;melting' temperature (T(m)) in 5mm-acetic acid of type-III collagen was almost 2 degrees C above that of type-I collagen. Intramolecular covalent cross-linking had no effect on the thermal stability.
Fermi Level Position at Metal-Semiconductor Interfaces (1964)

The position of the Fermi level at a metal-semiconductor interface relative to the conduction band has been found to be a constant fraction of the semiconductor band gap for all but 3 of the 14 group IV or III-V semiconductors studied. In all cases, the position was essentially independent of the metal work function. This general result is not inconsistent with the limited theories of surface state energies now available. The three exceptional cases can be understood in terms of a first-order perturbation to the surface state energies correlated with a similar perturbation observed in the energy gap at the (111) zone edge. Experiments are also reported on Ga(As-P) alloys, and two II-VI materials showing distinctly different behavior.
Compounds from<i>Lactobacillus plantarum</i>culture supernatants with potential pro-healing and anti-pathogenic properties in skin chronic wounds (2014)

The molecules and biological activities found in LAPS could explain the observed effects in human chronic wounds.
Fish as forbidden food: The case of India (1974)

This paper is concerned with the avoidance of fish as human food in the Indian subcontinent and nearby areas, from a cultural and historical point of view. Three factors are identified that now influence, or may have once influenced people to avoid fish. First there is the view that fish are dirty creatures and that fishing and fish‐eating are low‐class activities; this is especially common in areas of nomadic tradition. Second there is belief in sacred water and sacred fish, in connection with the worship of particular deities such as Vishnu. There is also a commitment to ahlmsã and vegetarianism, concepts prominent in Jainism and other religions of Indian origin, and observed according to a person's role, class, and sectarian affiliation. The manifestation of attitudes against fishing and fish‐eating are considered, and the conclusion is reached that the above and other historical, sociocultural, and ecological factors must be weighed in order to gain a balanced view of fish use and use of other potential foods by man.
Incoherent-scatter computed tomography with monochromatic synchrotron X-ray (2002)

We describe a new system of incoherent scatter computed tomography (ISCT) applied to in vivo imaging, and the reconstruction method for ISCT using the least squares method with singular value decomposition. The system operates on the basis of computed tomography (CT) of first generation. The preliminary experiment was carried out at the BLNE-5A bending magnet beam line of the Tristan Accumulation Ring in KEK, Japan. An acrylic cylinder of 20 mm diameter with a cross-shaped channel was imaged. The channel was filled with a diluted iodine solution of 200 /spl mu/g/ml. The detective system with a high purity germanium (HPGe) detector separated incoherent X-ray peak from other remarkable peaks, i.e., K/sub /spl alpha// and K/sub /spl beta//, X-ray fluorescent lines and coherent scattering peak. CT image was reconstructed from projections generated by integrating the counts in the energy window centered to the incoherent scattering peak with approximately 2 keV width.
Imaging with Intermolecular Multiple-Quantum Coherences in Solution Nuclear Magnetic Resonance (1995)

A magnetic resonance imaging technique based on intermolecular multiple-quantum coherences in solution (the correlated spectroscopy revamped by asymmetric z gradient echo detection or CRAZED experiment) is described here. Correlations between spins in different molecules were detected by magnetic-field gradient pulses. In order for a correlation to yield an observable signal, the separation between the two spins must be within a narrow band that depends on the area of the gradient pulses. The separation can be tuned from less than 10 micrometers to more than 1 millimeter, a convenient range for many applications.
Poisonous gas effects on the emission of oxide-coated cathodes (1987)

A study of the influence of various gases on the emission of oxide-coated cathodes is described. Particularly selected were SO2 and NO2, which are closely related to air pollution, and Cl2 gases. For comparison purposes, the poisonous effects of N2, CO2, H2O, O2, CO, H2, and Ar, which are the main components of natural atmosphere, were also examined. To study the influences of gases on the emission of oxide-coated cathodes and on oxide materials in more detail, the poisoned state of the contaminated cathode was analyzed using secondary electron microscopy and Auger electron spectroscopy. The influence of contaminated gases on the emission of the cathode in the carbonate state prior to activation was also studied.

Selective synthesis of poly-substituted fluorine-containing pyridines and dihydropyrimidines via cascade C–F bond cleavage protocol (2011)

Fluorinated azaheterocycles are frequently found in pharmaceuticals, drug candidates, ligands for transition metal catalysts, and other molecular functional materials, so efficient methods for the synthesis of these compounds are of significant value. We herein describe a selective strategy for the synthesis of poly-substituted pyridines and fluoroalkyl dihydropyrimidines based on C-F bond breaking of the anionically activated fluoroalkyl group. An array of pyridines and dihydropyrimidines were prepared through this domino process in high yields under noble metal catalyst-free conditions, making this method a valuable supplement to azaheterocycle synthesis.
Turbocharging a 6-Cylinder Diesel for Various Ratings and Applications (1981)

<div class="htmlview paragraph">Turbocharging of a basic engine type to suit different ratings and applications poses many problems. Careful design of components, choice of turbocharger match and supporting equipment are all critical in obtaining the optimum solution.</div> <div class="htmlview paragraph">The addition of turbocharging to an engine type permits it to leave behind some of the restraints of its naturally aspirated form. However other factors are encountered which set limits rather than offer advantages.</div> <div class="htmlview paragraph">The successful optimisation of all these factors within one engine type permits the benefits of component and configuration rationalisation to be realised while still retaining the performance diversity and flexibility necessary to meet the needs of the market place.</div>
Cell wall constituents of several siphoneous green algae in relation to morphology and taxonomy (1979)

Abstract Cell wall hydrolysates of the gametophytic phases of Bryopsis plumosa and Derbesia tenuissima contained large amounts (= percentages of more than 10) of xylose and glucose, whereas walls of the sporophytic phases contained large amounts of mannose and glucose. Xylan was demonstrated by infrared spectrometry in the cell walls of the gametophytic phases of these two species and mannan in the sporophytic phases. However the cell walls of both the gametophytic and sporophytic phases of the taxonomically related species Bryopsidella neglecta contained large amounts of xylose and glucose, and the presence of xylan in the cell wall of the sporophyte could be confirmed by infrared spectrometry. Mannan was also demonstrated in the cell walls of Codium and Pseudobryopsis. The hydrolysates of these walls contained large amounts of mannose. The hydrolysates of utricleless or juvenile stages of Codium also contained large amounts of glucose. Dominant monosaccharides in the cell walls of Caulerpa proved to be glucose, mannose and galactose, whereas only traces of xylose could be demonstrated in the cell walls of this species.
Advanced Motor Monitoring and Diagnostics (2014)

Modern motor protection relays are capable of long-term failure monitoring and diagnostics based on information collected by a powerful data acquisition system. This includes predicting lifetime of motors. This paper presents an advanced algorithm capable of performing such tasks. It is applicable to different types of rotating electric machines depending on their design. The components are as follows: stator turn fault detection and rotor bar fault detection. Detection methods are based on calculating the cross-coupled impedance and analyzing the current frequency signature of the motor. The presentation includes a theoretical background, simulated results, and testing results performed on a particular physical model.
Infant mortality and infant feeding in Puerto Rico. (1942)

Data on infant mortality and infant feeding in Puerto Rico were examined. The material studied was the infant and preschool records found in the active and pending files of the public health units. The information tabulated was that of the status of the child at the time of 1st admission to Health Department service, before any specific benefit could have been obtained from that service. A total of 1189 records was tabulated from 3 municipalities: 171 from Ciales; 360 from Guayama; and 658 from Rio Piedras. Results of the 2 sexes were combined. Breastfed means that the sole source of milk was breast. The proportion breastfed declined with advancing age of child. There was a striking difference between Ciales, an area of relatively low infant mortality, and the other 2 municipalities. The proportion breastfed in Ciales was definitely higher than in the other 2 communities in the 2-3 months group. The difference was even greater in the 4-5 months group. The total records from Ciales were only 171, but the differences were statistically significant. Rio Piedras was consistently the lowest in every age group. In the youngest age group of the children there was a decreasing proportion breastfed with the advancing age of the mother. This finding was statistically significant. In the group of children 6 months and older, it appeared that the older mothers had the highest proportion of breastfed children. In this group, the difference according to mother's age only approached significance. In regard to rural-urban differences, there was clearly little difference in the early months of life, but in the older age groups the proportion breastfed was higher for inhabitants of rural areas. These differences were significant and suggest that rural mothers tend to nurse their infants longer. There was no evidence that the rates for older infants in the rural areas were weighted with older mothers tending to have th e highest proportion of infants breastfed at age of 6 months and older. It is essential that the proper technique of breastfeeding be taught to all mothers, particularly to primiparas, as errors in technique may result in unnecessary artificial feeding. Physicians and nurses should become more familiar with the requisites for successful breastfeeding.
The Fall of the House of Ahab (1967)

The Omrides are remembered with disdain in the Old Testament. Little mention is made of the prosperity and wealth which Israel enjoyed during their day. The reader is told, instead, of their persecution of the Yahwistic prophets, their injustice to Naboth, and their Baalistic leanings. The biblical verdict upon this dynasty is presented most clearly in the account of Naboth's murder, 1 Kings xxi, and the account of Jehu's rebellion, 2 Kings ix 1-x 27. The second of these accounts attempts to justify Jehu's slaughter of the Omrides by calling attention to the fact that the prophets had predicted their terrible fate. It further implies that the prophets had made their attacks upon the royal family because of its Baalistic leanings, and that the chief purpose and result of Jehu's massacre in Jezreel was to replace the Baalistic dynasty with a Yahwistic one 1). It should be noted, however, that the names which Omri and Ahab chose for their children (Athaliah, Ahaziah, Jehoram) are compounded with Yahweh and thus do not suggest a preference for Baalism 2). Nor did Baalism come to a sudden end when Jehu ascended the throne. It is evident from the Samaria Ostraca that names compounded with Baal were common in Israel as late as the reign of Jeroboam II3). Indeed, if, as the author of the account of Jehu's rebellion implies, the matter of Israel's official religion or the personal religious leanings of the Omrides were all that was involved, the massacre in Jezreel would not appear as Yahwism's moment of victory over Baalism, but its moment of revenge. Jehoram had already put away
Nerve Growth Factor (1977)

Development of the Sympathetic Nervous SystemDetailed reviews of this subject have recently been published9,56 and should be consulted for additional facts and for a discussion of the development of preganglionic neurons. The general plan of sympathetic-nervous-system development in chicks and mammals is quite similar, but the earliest appearance of catecholamines in embryonic neuroblasts and the rate of maturation of the system vary with the species.56 Sympathetic development begins with migration of neural-crest cells ventrad into the mesenchyme between the neural tube and the myotome.32 These cells first take up residence in two columns dorsolateral to . . .
Decorin inhibits cell attachment to thrombospondin‐1 by binding to a KKTR‐dependent cell adhesive site present within the N‐terminal domain of thrombospondin‐1 (1997)

Skin decorin (DCN) is an antiadhesive dermatan sulfate-rich proteoglycan that interacts with thrombospondin-1 (TSP) and inhibits fibroblast adhesion to TSP [Winnemöller et al., 1992]. Molecular mechanisms by which DCN interacts with TSP and inhibits cell adhesion to TSP are unknown. In the present study, we showed that skin DCN and bone DCN (chondroitin sulfate-rich proteoglycan) were quantitatively identical with respect to their ability to interact with TSP. Using a series of fusion proteins corresponding to the different structural domains of TSP, binding of [125I]DCN to TSP was found to be dependent of the N-terminal domain and, to a lesser extent, of the type 1 repeats and the C-terminal domain of TSP. In addition, heparan sulfate drastically inhibited [125I]DCN binding to solid-phase adsorbed TSP (80% inhibition), suggesting that DCN could bind to the N-terminal domain of TSP through interaction with heparin-binding sequences. To address this question, a series of synthetic peptides, overlapping heparin-binding sequences ARKGSGRR (residues 22–29), KKTR (residues 80–83) and RLRIAKGGVNDN (residues 178–189), were synthesized and tested for their ability to interact with DCN. [125I]DCN interacted only with peptides VDAVRTEKGFLLLASLRQMKKTRGT and KKTRGTLLALERKDHS containing the heparin-binding consensus sequence KKTR. These peptides contained glycosaminoglycan-dependent and -independent binding sites because [125I]DCN binding to VDAVRTEKGFLLLASLRQMKKTRGT and KKTRGTLLALERKDHS was partially reduced upon removal of the glycosaminoglycan chain (65% and 46% inhibition, respectively). [125I]DCN poorly bound to subpeptide MKKTRG and did not bind at all to subpeptides VDAVRTEKGFLLLASLRQ and TLLALERKDHS, suggesting that heparin-binding sequence MKKTRG constituted a DCN binding site when flanked with peptides VDAVRTEKGFLLLASLRQ and TLLALERKDHS. The sequence VDAVRTEKGFLLLASLRQMKKTRGTLLALERKDHS constitutes a cell adhesive active site in the N-terminal domain of TSP [Clezardin et al., 1997], and DCN inhibited the attachment of fibroblastic and osteoblastic cells to peptides VDAVRTEKGFLLLASLRQMKKTRGT and KKTRGTLLALERKDHS by about 50 and 80%, respectively. Although fibroblastic cells also attached to type 3 repeats and the C-terminal domain of TSP, DCN only inhibited cell attachment to the C-terminal domain. Overall, these data indicate that modulation by steric exclusion of cell adhesion to a KKTR-dependent cell adhesive site present within the N-terminal domain of TSP could explain the antiadhesive properties of DCN.

The pharmacological effect of thyrotropin-releasing hormone on ataxic mutant mice (1986)

The Rolling mouse Nagoya (RMN), Staggerer, Weaver and Reeler, all of which show hereditary ataxia, were intraperitoneally injected with 25 mg/kg of thyrotropin-releasing hormone (TRH-T) or physiological saline, and changes in the motions of these animals were observed by an Animex II and an open field method. All four strains of mice with ataxia showed improvement of ataxia and an increase in the motion volume, but these changes were not necessarily consistent in degree. Improvement of ataxia was most marked in the RMN and the Staggerer, moderate in the Weaver and slight in the Reeler, which showed enhanced tremor. The relationship between the competence of transmitting information in the cerebellum and improvement of ataxia by the injection of TRH-T aroused our interest.
Formation of calcium carbonate particles by direct contact of Ca(OH)2 powders with supercritical CO2 (2006)

A novel method to obtain a high conversion of Ca(OH)2 powder to CaCO3 is reported. The method uses supercritical CO2 containing water that is passed over the dry Ca(OH)2 powder. Conversions greater than 98% are obtained. The dominant crystal structure is calcite. The process has the advantages of the conventional solution based process in terms of high conversion and the advantages of a gas–solid based process in that dry, non-agglomerated particles are obtained by simple venting of the solvent.
The 5′-Proximal Hairpin of Turnip Yellow Mosaic Virus RNA: Its Role in Translation and Encapsidation (2003)

The RNA genome of turnip yellow mosaic virus (TYMV) consists of more than 6,000 nucleotides. During a study of the roles of the two hairpins located in its 90-nucleotide 5' untranslated region, it was observed that stabilization of the 5'-proximal hairpin leads to a delay in the development of symptoms on plants. This delay in symptom development for both locally and systemically infected leaves was found to be dependent on a change in the free energy of the hairpin caused by introduced mutations. A protoplast transfection assay revealed that the accumulation of plus-strand full-length RNA and subgenomic RNA, as well as protein expression levels, was affected by hairpin stability. Stabilization of this hairpin inhibited translation. A model is proposed in which a destabilized 5'-proximal hairpin allows maximal translation of the viral proteins. It is suggested that this hairpin may exist in close proximity to the 5' cap as long as its stability is low enough to enable translation. However, at an acidic pH, the hairpin structure becomes more stable and is functionally transformed into the initiation signal for viral packaging. Slightly acidic conditions can be found in chloroplasts, where TYMV assembly is driven by a low pH generated by active photosynthesis.
