Thermographic properties of eight blue-emitting phosphors (1993)

We examined the effect of temperature on the light emission and absorption properties of eight phosphorescent compounds. The phosphors are commercially produced powders that emit mainly in the blue region when illuminated with ultraviolet light (220 to 400 nm). Excitation and emission spectra taken over the temperature range of 20 to 350C are presented for these phosphors. Data from the spectra indicate a strong temperature dependence over this temperature range. Maximum relative intensity changed as a function of temperature in every phosphor examined. In some samples, spectral band shifts and bandwidths also changed with temperature. Of these phosphors, BaMg{sub 2}Al{sub 16}O{sub 27}:Eu and Ba{sub 3}(PO{sub 4}){sub 2}:Eu are candidates for higher-temperature studies.

Six-sigma design (quality control) (1993)

The approach to customer satisfaction taken at Motorola is described. It is based on two conclusions derived from various studies: A product is built in the shortest time and at the lowest cost if no mistake is made in the process; and if no defect can be found anywhere in the process of building a product for the customer, then the customer probably will not find one either. Beginning in 1987, Motorola designers were required to adopt +or-6-sigma tolerance limits, i.e., product design margins were to be twice the normal variation of the process. The way in which this was implemented in a six-step design process is described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

A Compact Filtering 180$^{\circ}$ Hybrid (2011)

A novel compact filtering 180 <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$^{\circ}$</tex> </formula> hybrid utilizing coupled resonators is presented. The equivalent-circuit structure is just like a bandpass filter, thus the frequency response is filter-like. The sum and difference port operations respectively correspond to the symmetric and antisymmetric states; therefore, isolation between sum and difference ports is accomplished by geometrical symmetry.

Inversion-channel GaN metal-oxide-semiconductor field-effect transistor with atomic-layer-deposited Al2O3 as gate dielectric (2008)

Inversion n-channel GaN metal-oxide-semiconductor field-effect-transistors (MOSFETs) using atomic-layer-deposited Al2O3 as a gate dielectric have been fabricated, showing well-behaved drain I-V characteristics. The drain current was scaled with gate length (varying from 1to16μm), showing a maximum drain current of ∼10mA∕mm in a device of 1μm gate length, at a gate voltage of 8V and a drain voltage of 10V. At a drain voltage of 0.1V, a high Ion∕Ioff ratio of 2.5×105 was achieved with a very low off-state leakage of 4×10−13A∕μm. Both MOSFET and MOS capacitor showed very low leakage current densities of 10−8A∕cm2 at biasing fields of 4MV∕cm. The interfacial density of states was calculated to be (4–9)×1011cm−2eV−1 near the midgap.
A low noise quadrature subsampling mixer (2002)

Noise analysis of a subsampling mixer structure based on current signal sampling is performed. The calculations show that a promisingly low noise figure can be obtained. The results of the analysis are verified by high-level simulations and measurements of a test circuit designed for quadrature downconversion from a 1st IF of 44.87 MHz to a low IF of 13 kHz.
Condicionamiento kikóongo de un fenómeno fonético en el criollo palenquero (1989)

The effects of wheat bug infestation (Eurygaster spp. and Aelia spp.) on the composition of wheat gluten proteins and its influence on flour technological quality were investigated in the present study. Wheat samples of six wheat varieties, collected from two localities in northern Serbia, were characterized by significantly different level of wheat bug infestation. Composition of wheat gluten proteins was determined using sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS PAGE), while the selected parameters of technological quality were determined according to standard and modified empirical rheological methods (Farinograph, Extensograph, Alveograph, and Gluten Index). The surface morphology of the selected samples was viewed using scanning electron microscopy (SEM). Wheat from wheat bug-infested locality regardless of the variety had deteriorated technological quality expressed with higher Farinograph softening degree, lower or immeasurable Extensograph energy, and Alveograph deformation energy. The most important changes in the gluten proteins composition of bug-infested wheat were related to gliadin subunits with molecular weights below 75 kDa, which consequently caused deterioration of uniaxial and biaxial extensibility and dough softening during mixing.
Heterogeneity of the Filamentous Haemagglutinin of Bordetella pertussis Studied with Monoclonal Antibodies (1983)

The filamentous haemagglutinin of Bordetella pertussis has been purified from static, liquid culture supernatants and from extracts of cells grown on a solid medium. SDS-PAGE of the purified protein has shown multiple polypeptides with molecular weights ranging from 220 000 to about 58 000. By transferring the SDS-dissociated polypeptides to nitrocellulose paper and reacting with several monoclonal antibodies, it has been shown that many of the polypeptides are probably fragments of the polypeptide of highest molecular weight.
Time course of ureteral changes with obstruction (1976)

Chronic obstruction is characterized by a marked degree of ureteral dilatation and tortuosity which develops in the presence of a relatively low intraluminal pressure. To define the mechanism for the development of this relationship, the pressure-tension-deformation relationships of acute and chronically obstructed ureters were investigated. Rabbit ureters, in vivo, were obstructed and deformation correlated with intraluminal pressure. During the initial 3 h of obstruction, ureteral resting pressure increased from approximately 0 to 42 cm H2O, and diameter increased 16% with a slight increase in length. Subsequently, average wall tension (tensile stress) and intraluminal pressure declined, although deformation persisted. Between 6 h and 8 days after the onset of obstruction, intraluminal pressure remained essentially unchanged. During this time interval, ureteral deformation continued gradually and progressively as the ureter underwent creep both circumferentially and longitudinally. This was associated with a marked increase in average wall tension. At 8 days the diameter had increased by 170% and the length by 25%.
Photopolymerization of acrylates without photoinitiators with short‐wavelength UV radiation: A study with real‐time fourier transform infrared spectroscopy (2004)

Abstract This article reports on the UV photopolymerization of acrylates without photoinitiators. Initiation of the reaction was achieved by direct excitation of the acrylates during irradiation with short‐wavelength UV light by use of the 222‐nm emission of a KrCl * excimer lamp. The reactivity of various acrylates was studied by real‐time Fourier transform infrared–attenuated total reflection spectroscopy. The rate and the extent of the reaction within the layer were strongly dependent on the depth of penetration of UV light, which was determined by the molar extinction coefficient of the acrylate. © 2004 Wiley Periodicals, Inc.

Bleaching practices in Europe (1976)

Abstract Adsorption onto porous solids is used to remove from oils not only pigments but also several other minor components. Now that long established process steps such as degumming, neutralization, and washing have become even more effective, the technique of adsorption is being continually evaluated to ensure that no unjustified expenditure is allowed to continue. Practical advice is offered on bleaching procedures and the subsequent separation of the adsorbent from the oil.
On Permutation Switching Networks (1968)

Rearrangeable switching networks are considered as permutation generators. Two-by-two network arrays may be implemented in these networks using a β reversing element. Nested tree arrays of these elements may be used to synthesize rearrangeable switching networks which appear minimal. Multistage network arrays of these elements may be implemented within a single coordinate device.
Microbial Quality and Direct PCR Identification of Lactic Acid Bacteria and Nonpathogenic Staphylococci from Artisanal Low-Acid Sausages (2003)

Detection of six species of lactic acid bacteria and six species of gram-positive catalase-positive cocci from low-acid fermented sausages (fuets and chorizos) was assessed by species-specific PCR. Without enrichment, Lactobacillus sakei and Lactobacillus curvatus were detected in 11.8% of the samples, and Lactobacillus plantarum and Staphylococcus xylosus were detected in 17.6%. Enriched samples allowed the detection of L. sakei and S. xylosus in all of the samples (100%) and of Enterococcus faecium in 11.8% of the sausages. The percentages of L. curvatus, L. plantarum, Staphylococcus carnosus, and Staphylococcus epidermidis varied depending on the sausage type. L. curvatus was detected in 80% of fuets and in 57% of chorizos. L. plantarum was found in 50% of fuets and 100% of chorizos. S. epidermidis was detected in only 11.8% of fuets, and S. carnosus was detected in only 5.9% of chorizos. Lactococcus lactis, Staphylococcus warneri, and Staphylococcus simulans were not detected in any sausage type. From a microbiological point of view, 70.6% of the samples could be considered of high quality, as they had low counts of Enterobacteriaceae and did not contain any of the food-borne pathogens assayed.
Antioxidative Properties of Bee Pollen Extracts Examined by EPR Spectroscopy (2012)

Antioxidative Properties of Bee Pollen Extracts Examined by EPR Spectroscopy Bee pollen is a valuable and highly recognized source of exogenous antioxidants. The aim of these studies was to determine the antioxidant capacity of three types of bee pollen extracts: ethanol extracts of bee pollen, pepsin extracts of bee pollen and ethanol extracts of pepsin-digested bee pollen. Their antioxidant properties were determined with the use of electron paramagnetic resonance (EPR) and their ability to quench DPPH free radicals was estimated. The EPR results showed that ethanol extracts of pepsin-digested bee pollen (EEPP) had the highest antioxidative effect and the highest free radical DPPH scavenging potential. The pepsin extracts of bee pollen (PEP) had the weakest antioxidant capacity. The ability to quench DPPH free radicals was also the weakest one for this extract. An average antioxidative effect was recorded for ethanol extracts of bee pollen (EEP).

Effect of insecticide—synergist combinations on the survival of <i>Spodoptera exigua</i> (1993)

Abstract The chitin synthesis inhibitors diflubenzuron and teflubenzuron have recently become ineffective for the control of Spodoptera exigua in floricultural crops. An extended laboratory test with second‐instar larvae of S. exigua on Vicia faba plants was carried out to determine the influence of synergists on the biological activity of three benzoylphenyl ureas (BPUs). The co‐application of piperonyl butoxide, an oxidase inhibitor, did not increase the activity of diflubenzuron, teflubenzuron or hexaflumuron. The best results were obtained with diethyl maleate, for suppressing glutathione S ‐transferase activity, and with dimethoate, as a hydrolase inhibitor. A joint application of diflubenzuron (at a concentration which resulted in 43% survival) with diethyl maleate or dimethoate gave only 6.2 and 8.9% surviving larvae, respectively. In addition, development to fourth‐instar larvae was inhibited. The more stable teflubenzuron was synergized by both compounds to a much lesser extent than diflubenzuron. None of the synergists had a significant effect on the activity of hexaflumuron, which was the most potent insecticide of the three BPUs tested against S. exigua .
Untersuchungen über die Konformation des cyclischen Hexapeptids <i>cyclo</i>‐Glycyl‐<scp>L</scp>‐prolyl‐glycyl‐glycyl‐<scp>L</scp>‐prolyl‐glycyl mittels protonenmagnetischer Resonanz und Parallelen zum Cyclodecapeptid Gramicidin S. 14. Mitteilung über homodet cyclische Polypeptide [1] [2] (1969)

Abstract The first proton magnetic resonance observations made with cyclic hexapeptides suggested the presence of two types of amide protons: one participating in intramolecular hydrogen bonds and more strongly shielded, the other exposed to the solvent and less shielded (S CHWYZER , et al. 1964 [2]). This was taken as evidence for the β‐type structure proposed for homodetic cyclic peptides with 2 · (2n + 1) amino acid residues in the ring (S CHWYZER [4]), n = 1, 2, 3 … These conclusions have now been confirmed by studies on the solvent dependence of chemical shifts in cyclo ‐glycyl‐prolyl, cyclo ‐glycyl‐prolyl‐glycyl‐glycyl‐prolyl‐glycyl (III) and gramicidin S. On passing from a typical amide proton acceptor solvent (hexadeuterodimethylsulfoxide or tetradeuteromethanol) to trifluoroacetic acid the solvent‐exposed protons become more shielded and the intramolecularly hydrogen bonded ones less so (Figure 5). The proposed β‐structure of the cyclodecapeptide gramicidin S (n = 2 in the above formula; H ODGKIN & O UGHTON [8], crystalline state; S CHWYZER [9], in solution) which has recently been supported by side‐chain interaction studies (using a nuclear magnetic resonance marker) on the biologically active derivative, diphthalylgramicidin S (S CHWYZER & L UDESCHER [1]) as well as by other methods [6] [7], is thus additionally supported. Our experiments, as well as those of K OPPLE [11], strongly favor a β‐structure for simple cyclohexapeptides in solution; this is particularly true for compound III which is, with respect to the two proline residues, a model of gramicidin S.
Outcome after Relapse among Children with Standard Risk (SR) ALL Treated on CCG-1952. (2004)

Abstract The event-free survival (EFS) of children with SR-ALL is now > 80%. Nonetheless, ALL relapse remains a major problem in pediatric cancer, and optimal therapy for these children remains to be defined. We examined post relapse outcomes for children initially treated on the Children’s Cancer Group CCG-1952 study and compared stem cell transplant (SCT) with chemotherapy (CT) as salvage treatment in second remission (CR2). Between 5-96 and 1-00, 2176 eligible patients with SR-ALL (WBC < 50,000/mcl; age ≥ 1, < 10 years) were enrolled on CCG-1952, 321 of whom experienced a relapse after initially achieving M1 remission. Among the relapses, 196 are bone marrow (BM) ± extramedullary (EM) relapses (61%) and 125 are isolated EM (iEM: CNS, testicular, or ocular) (39%) relapses. The mean time (range) from first remission to BM relapse, iCNS relapse, and itesticular relapse is 34 ± 1 (2 to 79) month (mo.), 22 ± 1 (1 to 70) mo., and 37 ± 3 (4 to 74) mo., respectively. The 3-year EFS and overall survival (OS) after relapse for all patients are 41% and 53%. Three-year EFS and OS after BM ± EM relapse are 32% and 40% and after iEM relapse are 55% and 71%. Patients with early BM relapse (CR1 < 36 months) or early iEM relapse (CR1 < 18 months) are 2.3 times (p=0.002) and 2.8 times (p=0.01) more likely to suffer a subsequent adverse event than patients with later relapse by Cox regression analysis after adjustment for age, pre-relapse treatment, day 7/14 BM status, and type of treatment in CR2. The 3-year OS for early and late relapses are 31% vs 59% (p=0.001) for BM relapse and 50% vs 87% (p=0.01) for iEM relapse. We compared 73 SCT and 215 CT patients, excluding 33 patients with adverse events prior to the median time to SCT (130 days, range 56 to 1148 days) using Kaplan-Meier life table analysis and the log rank test. The cohorts are similar with respect to age (p=0.57), duration of CR1 (p=0.96), and initial Day 14 BM status (p=0.69). Thirty-seven percent (n=62) of patients with BM relapse (33 early; 29 late) and 9% (n=11) of patients with iEM relapse (6 early, 5 late) received SCT. Thus far, outcomes are similar between cohorts for patients with any BM relapse (OS, p=0.45; EFS, p=0.70), early BM relapse (OS, p=0.95; EFS, p=0.66), and iEM relapse (OS, p=0.44; EFS, p=0.96). Among patients with later BM relapse, a trend favors CT (OS, p=0.08; EFS, p= 0.14). In summary, duration of CR1 remains the most significant predictor of outcome after either BM or iEM relapse in this SR-ALL cohort. Prognosis after early BM relapse remains poor with either SCT or CT.
THE LEPTOTENE-ZYGOTENE TRANSITION OF MEIOSIS (1998)

The leptotene/zygotene transition of meiosis, as defined by classical cytological studies, is the period when homologous chromosomes, already being discernible individualized entities, begin to be close together or touching over portions of their lengths. This period also includes the bouquet stage: Chromosome ends, which have already become integral components of the inner nuclear membrane, move into a polarized configuration, along with other nuclear envelope components. Chromosome movements, active or passive, also occur. The detailed nature of interhomologue interactions during this period, with special emphasis on the involvement of chromosome ends, and the overall role for meiosis and recombination of chromosome movement and, especially, the bouquet stage are discussed.
Regulation of expression by promoters versus internal ribosome entry site in the 5'-untranslated sequence of the human cyclin-dependent kinase inhibitor p27kip1 (2005)

p27kip1 regulates cell proliferation by binding to and inhibiting the activity of cyclin-dependent kinases and its expression oscillates with cell cycle. Recently, it has been suggested from studies using the traditional dicistronic DNA assay that the expression of p27kip1 is regulated by internal ribosome entry site (IRES)-mediated translation initiation, and several RNA-binding protein factors were thought to play some role in this regulation. Considering the inevitable drawbacks of the dicistronic DNA assay, which could mislead a promoter activity or alternative splicing to IRES as previously demonstrated, we decided to reanalyze the 5'-untranslated region (5'-UTR) sequence of p27kip1 and test whether it contains an IRES element or a promoter using more stringent methods, such as dicistronic RNA and promoterless dicistronic and monocistronic DNA assays. We found that the 5'-UTR sequence of human p27kip1 does not have any significant IRES activity. The previously observed IRES activities are likely generated from the promoter activities present in the 5'-UTR sequences of p27kip1. The findings in this study indicate that transcriptional regulation likely plays an important role in p27kip1 expression, and the mechanism of regulation of p27 expression by RNA-binding factors needs to be re-examined. The findings in this study also further enforce the importance that more stringent studies, such as promoterless dicistronic and monocistronic DNA and dicistronic RNA tests, are required to safeguard any future claims of cellular IRES.
