Creating New Opportunities for Ecosystem Restoration on Public Lands: An Analysis of the Potential for Bureau of Land Management Lands (2002)

The northern high plains of the western central United States once housed one of the world's most spectacular aggregations of wildlife.As William Clark, standing near Great Falls on the Missouri River in north central Montana described it in 1805, "immence herds of Buffaloe, Elk, deer, & Antelopes feeding in one common and boundless pasture."' Today, the native short grass prairies that sustained this fecundity of animal biomass are dwindling.Yet large expanses of native vegetation in the Northern High Plains Steppe Ecoregion still remain intact?The World Wildlife Fund (WWF) recognizes the ecoregion as "globally outstanding" in terms of potential for biodiversity conservation. 4 The WWF gives the region a high conservation priority due to the number of globally imperiled species inhabiting the area, the potential for supporting numerous conservation targets, and the threat of development from agricultural conversion. 5The intact nature of the ecoregion's natural vegetation and land management provides an opportunity to link habitats and contribute to functional largescale processes, while at the same time providing a buffer from incompatible activities. 6 Bureau of Land Management (BLM) lands represent a unique class of public lands.In the northern plains states, these are lands that were not claimed or set-aside during the land settlement boom of the late Nineteenth and early Twentieth century. 7As such, their value was historically regarded as economically circumspect, and their contribution to global bi-8.Id. 9.

Molecular basis for therapy resistance (2010)

Chemoresistance remains the main reason for therapeutic failure in breast cancer as well as most other solid tumours. While gene expression profiles related to prognosis have been developed, so far use of such signatures as well as single markers has been of limited value predicting drug resistance. Novel technologies, in particular with regard to high through-put sequencing holds great promises for future identification of the key "driver" mechanisms guiding chemosensitivity versus resistance in breast cancer as well as other malignant conditions.
Agency mulls laboratory regulation changes: Public reaction could influence future revisions (1992)

Federal officials, after receiving more than 7,000 letters from medical groups and individual physicians, are reacting to increased pressure to relax the regulatory burden on U.S. laboratories. In addition to the letters, a coalition of medical groups has presented the U.S. Health Care Financing Administration (HCFA) with copies of a new study showing that some 4,000 physician office labs, including 500 rural sites, might shut down or significantly reduce testing services as a result of new regulatory costs.

Over de verspreiding van Carex aquatilis Wahlenb (1957)

Het laatste decennium zijn van de boreale Carex aquatilis een aantal vindplaatsen in Groningen en in het noorden van Drente bekend geworden; plaatselijk groeit de soort hier vegetatievormend. Voor Europa wordt de soort verder vermeld uit: Ierland, W.- en N.-Engeland, Schotland, Ijsland, SkandinaviÃ« (doch naar het zuiden zeldzamer wordend), Finland, Rusland (naar het zuiden tot bij Leningrad) en Estland, bij Reval (zie Kern en Reichgelt, Fl. Neerl. I, 3, 1954, p.79). Daar volgens de literatuur Carex aquatilis niet bekend is uit Denemarken en Duitsland veronderstelt Mej. Dr. Ch.H. Andreas â mede op grond van het voorkomen van fossiele resten in de Nederlandse bodem â dat de soort in ons land een âglaciaal â relictâ is (N.K.A. 58, 1951, p. 48).\nSedert 1948 werd in N.W.-Overijsel geregeld naar de soort gezocht, doch eerst in de zomer van 1955 werd Carex aquatilis hier in een vrij groot aantal aangetroffen aan slootkanten en op lage plekken in weilanden langs de Nieuwe Dijk, die van Wanneperveen in de richting Meppel loopt. Dit gebied, dat uit in cultuur gebracht moerasveen bestaat, ligt aan beide zijden van de grens tussen N.W.-Overijsel en Z.W.-Drente. De soort groeit hier tezamen met Carex acuta L., C. nigra (L.) Reichard en C. rostrata Stokes, plaatselijk op lage plekken zelfs mm of meer vegetatievormend. Verder bleek het dat deze zegge in enige dichtgegroeide petgaten bij Kolderveen (Z.W.-Drente) voorkomt.

Neutrino mass and mixing with discrete symmetry (2013)

This is a review paper about neutrino mass and mixing and flavour model building strategies based on discrete family symmetry. After a pedagogical introduction and overview of the whole of neutrino physics, we focus on the PMNS mixing matrix and the latest global fits following the Daya Bay and RENO experiments which measure the reactor angle. We then describe the simple bimaximal, tri-bimaximal and golden ratio patterns of lepton mixing and the deviations required for a non-zero reactor angle, with solar or atmospheric mixing sum rules resulting from charged lepton corrections or residual trimaximal mixing. The different types of see-saw mechanism are then reviewed as well as the sequential dominance mechanism. We then give a mini-review of finite group theory, which may be used as a discrete family symmetry broken by flavons either completely, or with different subgroups preserved in the neutrino and charged lepton sectors. These two approaches are then reviewed in detail in separate chapters including mechanisms for flavon vacuum alignment and different model building strategies that have been proposed to generate the reactor angle. We then briefly review grand unified theories (GUTs) and how they may be combined with discrete family symmetry to describe all quark and lepton masses and mixing. Finally, we discuss three model examples which combine an SU(5) GUT with the discrete family symmetries A₄, S₄ and Δ(96).

Taxation Aspects of Foreign Investments in India (1980)

This paper will outline, discuss and suggest changes in various provisions of the Income Tax Act, 1961, applying to foreign investments. Chapter II of this paper explores the general underlying principles of the Indian tax system. Chapter III discusses the tax liability of foreign personnel in India and special tax incentives granted to foreign technicians. Chapter IV discusses the system of corporate taxation or “resident” and non-resident” companies and tax liability of foreign collaborators. Special attention is paid to the liability arising out of various trading activities of non-resident companies in India and many problems of judicial determination relating to such activities. Investment and savings incentives are discussed in Chapter V. Chapter VI discusses to what extent U.S. inventor is entitled to tax relief under U.S. foreign tax credit laws. The paper concludes with taking an overall view of the tax impact on foreign investments and to what extent foreign companies can benefit from India’s effort to attract investments.
Construction of Overlapping Oligonucleotide Templates for the Production of cRNA Standards for Quantitative Reverse Transcription Polymerase Chain Reaction (1993)

The reverse transcriptase polymerase chain reaction (PCR) is a technique for the study of gene expression that requires far less RNA for analysis than Northern blots. The inclusion of cRNA standards in the initial reverse transcription step is a way to control for the tube-to-tube variation often inherent in the technique and to permit quantitation of the starting amount of the native mRNA being analyzed. We describe a method using overlapping oligonucleotides to produce templates for the production of cRNA standards for up to three different mRNA species. The first step is the synthesis of a pair of overlapping oligonucleotides each of which encodes, respectively, sequences analogous to either sense or antisense primers for the PCR amplification of up to three different messages. These oligonucleotides are designed to have complementary 3' ends which permit spontaneous annealing and allow subsequent mutually priming extension of the annealed double-stranded portion by T7 DNA polymerase. The T7 and SP6 RNA polymerase promoters are then added to the ends of the template using standard PCR techniques. Once the template is assembled, T7 and SP6 RNA polymerases are used to produce copious quantities of cRNA standards and controls. This technique can be used to construct multiple cRNA standards for essentially any messages of interest. Production of cRNA by a single T7 RNA polymerase reaction yields standards sufficient for several thousand separate reverse transcriptions.
Synthesis and properties of soluble polypyrrole doped with dodecylbenzenesulfonate and combined with polymeric additive poly(ethylene glycol) (2005)

Abstract Soluble polypyrrole (PPy) samples advanced in electrical conductivity σ were chemically synthesized with dodecylbenzenesulfonate (DBS) sodium salt as a dopant, with poly(ethylene glycol) (PEG) as an additive, and with ammonium persulfate as an oxidant. The PPy–DBS–PEG samples were soluble in organic solvents ( N ‐methylpyrrolinone and m ‐cresol). The greater the molar percentage ratio was of DBS, the greater the solubility was of synthesized PPy composites (PPy–DBS–PEG). The maximum electrical conductivity at room temperature for PPy–DBS–PEG was 1.02 S/cm, which was in fact the true conductivity of 100/10 (mol %) PPy/DBS. The chemical composition and doping level of PPy–DBS–PEG were determined by elemental analysis. The results of Fourier transform infrared spectroscopy were used for the structural characterization of PPy–DBS–PEG. The scanning electron microscopy results showed that the electrical conductivity was related to the morphology of PPy–DBS–PEG. According to thermogravimetric analysis, PPy–DBS–PEG was more thermostable than PPy–DBS. Electron spin resonance measurements showed that the polaron and bipolaron acted as charge carriers of PPy–DBS–PEG. According to the temperature dependence of the electrical conductivity, PPy–DBS–PEG was a semiconductor and followed the three‐dimensional variable‐range hopping model. The improved electrical conductivity apparently resulted from the reduction of the crosslinking and structural defects of the PPy chains. © 2005 Wiley Periodicals, Inc.

Indole-Induced Activities of β-Lactamase and Efflux Pump Confer Ampicillin Resistance in Pseudomonas putida KT2440 (2017)

Indole, which is widespread in microbial communities, has received attention because of its effects on bacterial physiology. <i>Pseudomonas putida</i> and <i>Pseudomonas aeruginosa</i> can acquire ampicillin (Amp) resistance during growth on indole-Amp agar. Transcriptome, mutant, and inhibitor studies have suggested that Amp resistance induced by indole can be attributed to increased gene expression of <i>ttgAB</i> encoding two genes of RND-type multidrug efflux operons and an <i>ampC</i> encoding β-lactamase. Expression, enzyme activities, and mutational analyses indicated that AmpC β-lactamase is important for acquiring Amp resistance of <i>P. putida</i> in the presence of indole. Here, we show, for the first time, that volatile indole increased Amp-resistant cells. Consistent with results of the volatile indole assay, a low concentration of indole in liquid culture promoted growth initially, but led to mutagenesis after indole was depleted, which could not be observed at high indole concentrations. Interestingly, <i>ttgAB</i> and <i>ampC</i> gene expression levels correlate with the concentration of indole, which might explain the low number of Amp-mutated cells in high indole concentrations. The expression levels of genes involved in mutagenesis, namely <i>rpoS</i>, <i>recA</i>, and <i>mutS</i>, were also modulated by indole. Our data indicates that indole reduces Amp-induced heterogeneity by promoting expression of TtgABC or MexAB-OprM efflux pumps and the indole-induced β-lactamase in <i>P. putida</i> and <i>P. aeruginosa</i>.
Rapid profile measurements in ion implanted silicon (1972)

Ion beam etching has been used, in conjunction with the Van der Pauw technique, to determine the electrical profiles of implanted dopants in silicon, the profiles being obtained much more rapidly than by using the more usual anodic stripping. The damage produced by the ion beam must be taken into account, and this involves a simple correction to the depth scale. Profiles obtained for 40 kV B + implanted silicon, annealed at temperatures between 500 and 970 degrees C, are presented and briefly discussed.
Searching for Similarities in Nearly Periodic Signals With Application to ECG Data Compression (2006)

This paper proposes a new methodology to identify and correlate patterns on nearly periodic signal, based on signal simplification and clustering approaches. Using cubic Bezier curves some significant signal samples (control points), enabling to segment adequately the original signal, are extracted in a first step. Next, given the correlation among extracted control points, the detection of similarities within the overall signal is then performed through a clustering technique. Although the approach is useful for many types of signals, the compression of electrocardiogram signals (ECG) is here investigated. Results with standard MIT-BIH databases show promising compression ratios, in particular, high compression ratios are found for long duration signals, when the signal presents strong regularities
Noise robust estimate of speech dynamics for speaker recognition (2002)

The paper investigates the robustness of cepstral based features with respect to additive noise, and details two methods of increasing the robustness with minimal need for a-priori knowledge of the noise statistics. The first approach is a form of noise masking which adds a fixed offset to the linear spectral estimate. The second is a form of sub-band filtering, again in the linear domain, which estimates the dynamic content of the speech using Fourier transforms. This avoids negative values normally inherent in such filtering and which presents difficulties in deriving log estimates. Both methods are shown to provide useful levels of robustness to additive noise, for example, speaker identification error rates in SNR mis-matched conditions of 15 dB are reduced from 60.5% for standard mel cepstra to 13.3% and 24.1% for the two approaches respectively.
Triple C–H activation of 1,5-bis(di-tert-butylphosphino)-2-(S)-dimethylaminopentane on ruthenium gives a chiral carbene complex (2002)

Gastrin secretion in the menstrual cycle and pregnancy. (1982)

Gastrin (1--17) concentration was estimated under basal conditions in 12 menstruating women, and 42 women with normal pregnancy. In 10 women with normal pregnancy this hormone was also measured 10 days after delivery. In addition, gastrin was determined after stimulation with a standard protein meal in 7 menstruating women, 12 women with normal pregnancy and 14 women with complicated pregnancies. Umbilical vein blood levels of gastrin were also determined in 5 cases while, in 3 women serial hormone estimations were carried out for 24 hours after normal delivery. The mean (+/- SEM) basal gastrin concentration was 36.1 +/- 2.9 pg/ml in the productive and 45.4 +/- 2.0 in the secretory phase of the cycle (p less than 0.02). The mean basal concentration in normal pregnancy (60.4 +/- 5.4) was higher than that of the normal cycle as a whole (p less than 0.001), showed no significant variations related to the progress of pregnancy, and fell to normal cycle levels after delivery (42.1 +/- 2.9). In complicated pregnancies the mean hormone concentration (47.0 +/- 2.3) was lower than that of normal pregnancies (p less than 0.05) and similar to that of the secretory phase of the cycle. Gastrin responses to protein meal were similar in all 3 groups studied, with maximal concentration at 30 min, and a gradual decline thereafter. Umbilical vein blood levels of gastrin were generally higher than in maternal circulation but not significantly so. Serial estimations of gastrin after delivery failed to show any uniform pattern of changes. It is concluded that variations of gastrin secretion related to the phase of the menstrual cycle or the reproductive state may occur in women.
Prospective, Randomized Inpatient Study of Oral Metronidazole versus Oral Metronidazole and Rifampin for Treatment of Primary Episode of<i>Clostridium difficile</i>–Associated Diarrhea (2006)

We conclude that there is no role for routine rifampin as an adjunct to treatment with metronidazole for hospitalized patients with C. difficile-associated diarrhea. The cure rates for both treatment groups remain unacceptably low, and better treatments are urgently needed.
The versatility of polysorbate 80 (tween 80) as an ionophore (1999)

A number of experiments were performed to illustrate the unusual versatility of Polysorbate 80 (Tween 80) as an ionophore. New ions shown to be transported by it from and to water layers through a model membrane (CH2Cl2) include H3O+, Li+, Pb2+, Co2+, piperidinium ion, guanidinium ion, and Paraquat, while two complex ions resisted transport under the conditions used. "Reverse" transport of lipophilic guests (azobenzene, azulene, ferrocene) from and to organic solvents through water was also promoted by Tween 80, but C60 was not carried. Three water molecules were transported per molecule of KSCN by the Tween.
The headaches of phaeochromocytoma. (1975)

Of 27 patients with phaeochromocytoma, 20 were subject to headaches as a part of their symptom complex and 7 were not, in spite of the fact that 4 of the latter had experienced other forms of headache at other times. There was no correlation between the proportion of noradrenaline to adrenaline produced by the tumour and the presence or absence of headache or the nature of the headache. Liability to headache appeared to be linked with the rate of change in blood pressure and was not related to absolute values of blood pressure. Two patients experienced a "funny turn" typical of catecholamine release during a spontaneous migraine headache. The migraine headache became pulsatile and severe in one patient but was unaltered in the other. The variable duration and intensity of the headache in different patients can be explained by the pressor and cranial vasoconstrictor effects of the secreted amines which respectively enhance and diminish vascular headache.
