Field evaluation of Fourier transform infrared continuous emissions monitoring (FTIR CEM) systems (1995)

Recent environmental regulations, including the Clean Air Act and the Enhanced Monitoring Regulations, may require continuous emissions monitoring (CEM) of hazardous air pollutants (HAPs). A promising technique for this application is Fourier transform infrared spectroscopy (FTIR). FTIR spectroscopy can, in principle, be used to monitor virtually any gas phase species. Two evaluations of FTIR CEM systems are discussed. The first study, performed in 1993 - 94, compared two FTIR CEM systems on a side-by-side basis in an extended field test at two coal-fired electric power plants. The FTIR CEM systems monitored the legally mandated criteria pollutants and diluents (CO, CO<SUB>2</SUB>, NO, NO<SUB>2</SUB>, and SO<SUB>2</SUB>) as well as H<SUB>2</SUB>O. In addition, one system monitored two HAPs (HCl and HF) and NH<SUB>3</SUB>. The FTIR CEM measurements were compared with those from the compliance CEM systems at the facilities. Several relative accuracy test audits were also performed to verify the FTIR CEM accuracy. The second evaluation was recently commenced on behalf of the Environmental Protection Agency. In this study, FTIR CEM systems are evaluated specifically for the monitoring of HAP species by conducting laboratory and field tests. The evaluation culminates in the development of proposed performance specifications and protocols for FTIR CEM systems.

Cardiac‐Specific Disruption of Bin1 in Mice Enables a Model of Stress‐ and Age‐Associated Dilated Cardiomyopathy (2015)

Non-compensated dilated cardiomyopathy (DCM) leading to death from heart failure is rising rapidly in developed countries due to aging demographics, and there is a need for informative preclinical models to guide the development of effective therapeutic strategies to prevent or delay disease onset. In this study, we describe a novel model of heart failure based on cardiac-specific deletion of the prototypical mammalian BAR adapter-encoding gene Bin1, a modifier of age-associated disease. Bin1 deletion during embryonic development causes hypertrophic cardiomyopathy and neonatal lethality, but there is little information on how Bin1 affects cardiac function in adult animals. Here we report that cardiomyocyte-specific loss of Bin1 causes age-associated dilated cardiomyopathy (DCM) beginning by 8-10 months of age. Echocardiographic analysis showed that Bin1 loss caused a 45% reduction in ejection fraction during aging. Younger animals rapidly developed DCM if cardiac pressure overload was created by transverse aortic constriction. Heterozygotes exhibited an intermediate phenotype indicating Bin1 is haplo-insufficient to sustain normal heart function. Bin1 loss increased left ventricle (LV) volume and diameter during aging, but it did not alter LV volume or diameter in hearts from heterozygous mice nor did it affect LV mass. Bin1 loss increased interstitial fibrosis and mislocalization of the voltage-dependent calcium channel Cav 1.2, and the lipid raft scaffold protein caveolin-3, which normally complexes with Bin1 and Cav 1.2 in cardiomyocyte membranes. Our findings show how cardiac deficiency in Bin1 function causes age- and stress-associated heart failure, and they establish a new preclinical model of this terminal cardiac disease.

All-optical wavelength conversion using cavity dumpedfibre laser with nonlinear optical loop mirror (1997)

The authors demonstrate a novel method of an all-optical wavelength conversion scheme by using a cavity dumped fibre laser with a nonlinear optical loop mirror. The measured on-off contrast ratio of the wavelength converted signal is much better than that of the input data signals, which may be very useful in practical high speed WDM communication systems.

Tanford–Kirkwood electrostatics for protein modeling (1999)

Solvent plays a significant role in determining the electrostatic potential energy of proteins, most notably through its favorable interactions with charged residues and its screening of electrostatic interactions. These energetic contributions are frequently ignored in computational protein design and protein modeling methodologies because they are difficult to evaluate rapidly and accurately. To address this deficiency, we report a revised form of the original Tanford-Kirkwood continuum electrostatic model [Tanford, C. & Kirkwood, J. G. (1957) J. Am. Chem. Soc. 79, 5333-5339], which accounts for the effects of solvent polarization on charged atoms in proteins. The Tanford-Kirkwood model was modified to increase its speed and to improve its sensitivity to the details of protein structure. For the 37 electrostatic self-energies of the polar side-chains in bovine pancreatic trypsin inhibitor, and their 666 interaction energies, the modified Tanford-Kirkwood potential of mean force differs from a computationally intensive numerical potential (DelPhi) by root-mean-square errors of 0.6 kcal/mol and 0.08 kcal/mol, respectively. The Tanford-Kirkwood approach makes possible a realistic treatment of electrostatics in computationally demanding protein modeling calculations. For example, pH titration calculations for ovomucoid third domain that model polar side-chain relaxation (including >2 x 10(23) rotamer conformations of the protein) provide pKa values of unprecedented accuracy.
Natural Organic Matter Removal from Drinking Water by Membrane Technology (2012)

Aquatic natural organic matter (NOM) is a heterogeneous mixture of biopolymers and their degradation products that cause harmful by-products during drinking water production. The great variability in NOM composition makes it difficult to completely remove from drinking water by any single technique. The current article reviews the NOM removal by micro-, ultra- and nanofiltration and by hybrid processes combining membrane techniques with other unit processes: coagulation, adsorption, and oxidation, and by membrane bioreactors.
A rare form of narcolepsy (HLA-DR2???) shows possible association with (functionally relevant) alpha-interferon gene polymorphisms (2004)

Narcolepsy is a neuropsychiatric disease caused by complex disturbance of sleep regulation. The main symptoms comprise daytime sleepiness and cataplexy. Although the aetiology remains unclear so far, narcolepsy is genetically characterized by strong linkage to the human leukocyte antigen complex as more than 90% of the patients are typed HLA-DR2+. Recently, it has become apparent that the orexin (hypocretin) neurotransmitter system plays a key role in the pathogenesis of the disease. Canine narcolepsy is caused by mutations in the orexin receptor 2 gene, and narcoleptic patients show specifically decreased cerebrospinal fluid orexin levels. Decreased promotor activity of the prepro-orexin gene is caused by binding of alpha-interferon in vitro. To investigate the possible role of IFNA gene polymorphisms in the pathogenesis of narcolepsy, we have genotyped two single nucleotide polymorphisms in IFNA genes as well as a neighbouring microsatellite. No association was evident in the prevalent DR2+ group. Yet, the IFNA10 single nucleotide polymorphisms and the IFNA microsatellite are associated with the DR2- patient group. Thus, the pathogenetic role of interferons needs to be defined in DR2- narcolepsy.
<title>Hybrid image processing instantiation: I. Optical subsystem</title> (1998)

We describe the optical correlator subsystem of a hybrid vision system. The optical correlator has a Kopin SLM at the input plane and a fast analog nematic Boulder Nonlinear Systems SLM at the filter plane. Filters are computed to provide identification and pose estimation for various objects. Spatial non-uniformities in the filter SLM are particularly bothersome from an operational standpoint. Methods of measuring and accommodating for the non- uniformities are described. Correlation filters produce an initially coarse identification, and later filters are intended to refine the coarse estimate of the pose of the observed object. Certain image preprocessing operations and their results are discussed; these include the cross- correlation that result when a Laplacian of Gaussian image is used as input to the system whose filter has been computed for a Sobel edge-extracted version of the reference image.

The effects of irrigated agriculture on the transmission of urinary schistosomiasis in the Middle and Upper Valleys of the Senegal River basin (2000)

The importance of the increase in irrigated land on the perimeters of the Middle and Upper Valleys of the Senegal River basin, on the prevalence and intensity of urinary schistosomiasis, was investigated. Surveys were conducted, in May-June 1997, to determine the prevalence and intensity of Schistosoma haematobium infection among 1445 children aged 7-14 years: 1011 in 10 villages near Matam, and 434 in four villages near Bakel. Macrohaematuria was present in seven of the study villages (four near Matan and three near Bakel), whereas microhaematuria was present in all the villages, with prevalences of 10%-73%. A second survey, conducted, in June 1999, on 755 children from nine of the study villages near Matam, demonstrated significant increases in the prevalences of both micro- and macro-haematuria in three of the villages, all of which were adjacent to the Senegal River and practising irrigated agriculture. None of the other study villages re-surveyed was irrigating any of its agricultural land. A longitudinal survey was also carried out, between May 1997 and November 1998, on about 10% of the population (2272 subjects) of Nguidjilone, north of Matam; selective treatment with praziquantel (40 mg/kg) was given in May 1997, and mass treatment in May 1998. The data analysed were those relating to the 125 individuals who provided samples at each survey. Very severe infections (> 1000 eggs/10 ml urine) were seen in five subjects in May 1997. One year later (i.e. 1 year after the selective treatment), the prevalence of urinary schistosomiasis had increased in every age-group. Although prevalence had decreased slightly by November 1998 (6 months after the mass treatment), the intensity of the infections seen had increased in every age-group. At the end of the dry season (May-June 1997), Bulinus truncalus infected with schistosome cercariae were recovered from the Senegal River. However, immediately after the next rainy season (November 1997), no snails were found at any collection site on the river.
A Mild, Nonbasic Synthesis of Thioethers. The Copper-Catalyzed Coupling of Boronic Acids with <i>N</i>-Thio(alkyl, aryl, heteroaryl)imides (2002)

[reaction: see text] A new synthesis of thioethers is described. The reaction of boronic acids with aryl, heteroaryl, and alkyl N-thioimides in the presence of catalytic quantities of a Cu(I) carboxylate affords good to excellent yields of thioethers. This reaction takes place in the absence of a base under mild conditions (THF, 45-50 degrees C, 2.5-12 h) and represents an interesting complement to known methods for thioether synthesis.
Induction of Apoptosis in Neuro-2A Cells by Zn2+ Chelating. (1998)

Metal ions such as Ca2+, Mg2+, or Zn2+, are important for many cell functions, for example, signal transduction and the modulation of enzyme activity. The relationship between apoptosis and metal cations, especially Ca2+, has been described in many reports. We have investigated the role of metal cations in the regulation of apoptosis in the mouse neuroblastoma cell line, Neuro-2A. When Neuro-2A cells were treated with ethylene diaminetetraacetic acid (EDTA), apoptosis was detected as growth inhibition, DNA fragmentation with a ladder pattern in agarose gel electrophoresis, and nuclear decomposition. However, in case of the treatment with ethylene glycol bis- (beta-aminoethyl ether) N,N,N',N'-tetraacetic acid (EGTA), which has a higher chelating specificity for Ca2+ than EDTA, DNA fragmentation was not detected. Moreover, the apoptosis induced by EDTA was inhibited by exogenous Zn2+. The membrane permeable Zn2+ chelator N,N,N',N'-tetrakis (2-pyridylmethyl)ethylenediamine (TPEN) also induced apoptosis of the Neuro-2A cells, and addition of equimolar exogenous Zn2+ or Cu2+, but not Mn2+ or Fe2+, prevented TPEN-induced apoptosis. The results suggest that Zn2+ may be a key regulator of apoptosis in Neuro-2A cells.
Studies on calcium uptake by myornetrial microsomes with particular reference to the dependence on inorganic phosphate and oxalate (1978)

Abstract Ca uptake by microsomes isolated from non‐pregnant rabbit myometrium was potentiated by both inorganic phosphate (Pi) and oxalate anions. Both P i and oxalate bad little effect on the initial rate of uptake but a pronounced effect on the capacity of Ca uptake measured after 20 min which was greater in the presence of oxalate than that of Pi (5 mM each). The presence or absence of sucrose in the uptake medium had a significant effect on oxalate‐induced potentiation of Ca uptake but not on that potentiated by Pi or that measured in the absence of either potentiating anion. A part of Ca accumulated additionally under the influence of sucrose could be removed by washing microsomes with KCI. Another significant difference between the pontentiating effect of oxalate and Pi was observed when the pH of the incubation medium was varied. In the presence of oxalate the pH optimum was between 6.46.8, whereas that in its absence or in the presence of Pi the optimal pH was around 7.2. Reduction in pH from 7.2 to 6.8 along with the substitution of KCI by sucrose resulted in 3‐fold increase in Ca uptake when oxalate was used as the potentiating anion. The results suggest that Ca is taken up by a different mechanism in the presence of oxalate than that in its absence or when oxalate anion is substituted with inorganic phosphate.

Association of Human Leukocyte Antigen (HLA)-B5 and -BW22-J with Hepatic Cirrhosis of Apparently Unknown Etiology (1977)

The majority of patients with hepatic cirrhosis in Japan do not have a history of acute hepatitis or alcoholism. Twenty-nine patients with hepatic cirrhosis which were thought as random samples from cirrhotic patients without a history of acute hepatitis or alcoholism were Human Leukocyte Antigen (HLA) typed. Association of HLA-B5 and -BW22-J with hepatic cirrhosis of apparently unknown etiology was found in p less than 0.003, and p less than 0.01, respectively (128 controls). A predisposition linked to HLA-B5 or -BW22-J related gene or genes seems to play a role in the development of hepatic cirrhosis, at least in a substantial part of patients with hepatic cirrhosis of apparently unknown etiology in Japan.
Development of 3D Bit-Map-Based CAD and Its Application to Hydraulic Pump Model Fabrication (2002)

A novel 3D bit-map-based CAD has been developed. This program, named CellCAD, relies on techniques which provides easy manipulation of huge sized 3D bit-map, poly-triangle and 2D bit-map data. It can be attached to various kinds of additional plug-in processors to extend its functions and to customize it highly for broad applications. CellCAD can be applied in fields using computed tomography digitizers and/or layering fabricators. The authors applied CellCAD to hydraulic pump model fabrication. This paper reports the basic design concept and implementation techniques of CellCAD from the viewpoint of design engineering, and also introduces the methods and results of an actual CellCAD application.

Adenosine 3',5'-Monophosphate-dependent and -independent Protein Phosphokinase Isoenzymes from Mammary Gland (1971)

Abstract Two protein phosphokinases (I and II) which show a high degree of substrate specificity for histones have been partially purified from rat mammary gland. Both enzymes are present in the cytosol, since 98% of the phosphoprotein kinase activity was recovered in the soluble fraction of mammary gland homogenates. Each enzyme incorporated the terminal phosphate of ATP into seryl and threonyl residues of all the histone fractions. The activity of protein kinase II was markedly stimulated by cyclic adenosine 3',5'-monophosphate, and the apparent Km of the enzyme was 0.03 µm for this cyclic nucleotide. The enzyme was also activated by other cyclic nucleotides with apparent Km values in the range of 1 to 3 µm. Mammary protein kinase I was not activated by cyclic nucleotides. The sedimentation constant s20,w of protein kinase I was 2.3 S, whereas that of protein kinase II was 3.2 S, as determined in isokinetic sucrose density gradients. Analysis of the 32P-histone products by amino acid analysis, tryptic peptide mapping, and electrophoretic fractionation revealed that the reactivities of the two enzymes with histones were nearly identical. Cyclic adenosine 3',5'-monophosphate increased coordinately the rates of phosphorylation of all the major histone fractions by protein kinase II. This increase involved the increased rate of phosphorylation of the major phosphopeptide residues, and no new sites of phosphorylation were observed as a result of activation by this cyclic nucleotide.
Визуализация динамических графов для анализа сложных сетей (2010)

The work describes a technique for dynamic graph visualization that helps us to analyze complex networks. Our method builds layouts for a sequence of graphs, while preserving the mental map. We show how to modify force-directed algorithms for the dynamic graphs. The proposed method is applied for visualization of several social networks. The experiments demonstrate the effectiveness of dynamic graph drawing for analyzing real-world data and the evolution of social relationships changing over time.
Photodissociation of Fe(CO)5 at 193 nm (1988)

Synchronization of Estrus and Ovulation in Swine (1959)

Induced ovulations were observed in gilts injected intramuscularly with Armour's Pituitary Gonadotrophin, FSH. The FSH was administered at levels ranging from 20 to 40 Armour Units per gilt. Five to 80 mg. of estradiol benzoate was injected intramuscularly 1 day after a FSH injection to induce boar acceptance in conjunction with induced ovulations. The exogenous estrogen had little effect in promoting estrus in gilts injected during the luteal phase of the estrous cycle, whereas estrus was induced by treatment during the early follicular phase. Eight out of 16 gilts given a single injection of FSH at various stages of the estrous cycle showed boar acceptance 18 to 23 days after this hormone was administered. Sixty-five of 73 ova recovered from these gilts showed cleavage stages of two or more blastomeres. Estrus was induced in ovariectomized gilts administered 0.2 mg. of estradiol benzoate per 100 lb. of body weight. However, estrus was not observed in animals receiving 1 mg. of this estrogen and a single injection of progesterone at the rate of 50, 100 or 200 mg. per 100 lb. body weight.
