Phys Rev Lett. 2001 Apr 30;86(18):3969-72. doi: 10.1103/PhysRevLett.86.3969.

We report results of a search for flavor-changing neutral current (FCNC), lepton flavor, and lepton-number violating decays of the D0 (and its antiparticle) into three and four bodies. Using data from Fermilab charm hadroproduction experiment E791, we examine modes...

An Sist Sanit Navar. 1997 Jan-Apr;20(1):47-55. doi: 10.23938/ASSN.0597.

There is an evident imbalance between the number of patients awaiting a kidney transplant and the availability of organs proceeding from donors with brain death. A high number of patients die each day from heart failure, whose organs could...

Mercury determination by CV-AAS in wastewater and sewage sludge from a stabilization pond system.

Analytical and bioanalytical chemistry

Araujo K, Colina M, Mazurek R, Delgado J, Ledo H, Gutierrez E, Herrera L.

Anal Bioanal Chem. 1996 Jun;355(3):319-20. doi: 10.1007/s0021663550319.

The mercury concentrations in wastewater and sewage sludge of a stabilization pond system have been evaluated. The system is built by three parallel facultative ponds followed by two systems of three maturation ponds in series. The samples of wastewater...

Self-adaptive sampling rate data acquisition in JET's correlation reflectometer.

The Review of scientific instruments

PMID: 19068534
Rev Sci Instrum. 2008 Oct;79(10):10F336. doi: 10.1063/1.2965011.

Data acquisition systems with self-adaptive sampling rate capabilities have been proposed as a solution to reduce the shear amount of data collected in every discharge of present fusion devices. This paper discusses the design of such a system for...

Gold binding by native and chemically modified hops biomasses.

Bioinorganic chemistry and applications

López ML, Gardea-Torresdey JL, Peralta-Videa JR, de la Rosa G, Armendáriz V, Herrera I, Troiani H, Henning J.
PMID: 18365087
Bioinorg Chem Appl. 2005;29-41. doi: 10.1155/BCA.2005.29.

Heavy metals from mining, smelting operations and other industrial processing facilities pollute wastewaters worldwide. Extraction of metals from industrial effluents has been widely studied due to the economic advantages and the relative ease of technical implementation. Consequently, the search...

Isostructuralism among bridge-flipped' isomeric benzylideneanilines and phenylhydrazones.

Acta crystallographica. Section B, Structural science

Ojala WH, Smieja JM, Spude JM, Arola TM, Kuspa MK, Herrera N, Ojala CR.
PMID: 17507762
Acta Crystallogr B. 2007 Jun;63:485-96. doi: 10.1107/S0108768107018034. Epub 2007 May 16.

Bridge-flipped' isomers may be defined as pairs of molecules related by a reversal of a bridge of atoms connecting two major parts of the individual molecules. This kind of isomerism is commonly found among benzylideneanilines and phenylhydrazones. Isostructural pairs...

Theory of connectivity for formally symmetric operators.

Proceedings of the National Academy of Sciences of the United States of America

Herrera I.
PMID: 16592459
Proc Natl Acad Sci U S A. 1977 Nov;74(11):4722-5. doi: 10.1073/pnas.74.11.4722.

A previous paper introduced the notion of complete connectivity conditions and developed variational principles for diffraction problems subjected to such restrictions. Here, an abstract definition of formally symmetric operators is given and it is shown that the problem of...

Narrow (n,m)-distribution of single-walled carbon nanotubes grown using a solid supported catalyst.

Journal of the American Chemical Society

Bachilo SM, Balzano L, Herrera JE, Pompeo F, Resasco DE, Weisman RB.
PMID: 16220926
J Am Chem Soc. 2003 Sep 17;125(37):11186-7. doi: 10.1021/ja036622c.

Unusually structure-selective growth of single-walled carbon nanotubes (SWNTs) has been attained using a CVD method with a solid supported catalyst. In this method, CO feedstock disproportionates on silica-supported catalytic nanoclusters of Co that are formed in situ from mixed...

Stereoselective one-pot synthesis of substituted (4Z)-2-alkyl-4-benzylidene- 4H-1,3-benzothiazines.

The Journal of organic chemistry

PMID: 15202918
J Org Chem. 2004 Jun 25;69(13):4545-7. doi: 10.1021/jo049777r.

Substituted (4Z)-4-benzylidene-2-methyl-4H-1,3-benzothiazines (1). and (4Z)-2-ethyl-4-benzylidene-4H-1,3-benzothiazines (2). were synthesized by direct stereoselective reactions of S-phenyl ethanethioate or S-phenyl propanethioate with substituted benzyl nitriles in the presence of triflic anhydride.

General variational principles applicable to the hybrid element method.

Proceedings of the National Academy of Sciences of the United States of America

Proc Natl Acad Sci U S A. 1977 Jul;74(7):2595-7. doi: 10.1073/pnas.74.7.2595.

Functional valued operators are used to formulate diffraction problems in a general abstract form. Variational principles for this formulation are developed. They are then applied to derive results on the linearized theory of free surface flows previously reported. Applications...

Tellurium adatoms as an in-situ surface probe of (111) two-dimensional domains at platinum surfaces.
