-
(Taylor & Francis Group, 1996-05-01)Structurally new N1aryl‐N2‐dichloroacetyl glycine and alaninamides were prepared. Greenhouse experiments were conducted to determine the effectiveness of the new compounds in protecting corn seedlings from chloroacetanilide ...
-
(Taylor & Francis Group, 1981-01-01)N2, Ar, O2, and CH4 in sedimentary pore waters of the Tama Estuary, Tokyo, were determined. The distributions of N2 and Ar reflected seasonal changes in these gases in the overlying water. N2/Ar ratios were always higher ...
-
(Taylor & Francis Group, 1982-01-01)Acetylene reduction by detached nodules of Alnus cordata, A. glutinosa and Colletia paradoxa was tested with respect to the effect of temperature on nitrogenase activity. Nodules were incubated at temperatures from 5°C to ...
-
(Taylor & Francis Group, 1991-01-01)After an oral dose of 100 mg of sulphaphenazole, the turtle Pseudemys scripta elegans excretes 27% of the compound unchanged and 3.8% as N4‐acetylsulphaphenazole. The expected glucuronide conjugate, sulphaphenazole‐N2‐glucuronide, ...
-
(Taylor & Francis Group, 1996-10-01)The chemoselective N-acylation of 2-amino alcohols with methyl 2,2-dichloro carboxylates occurs smoothly and in excellent yields.
-
(Taylor & Francis Group, 1992-07-01)N2-Isobutyryl-O6-[2-(p-nitrophenyl)ethyl]guanine (4) allows the synthesis of different types of carbocyclic analogs of guanosine in high yield under Mitsunobu conditions. Only the desired N9-substituted derivatives of ...
-
(Taylor & Francis Group, 1981-01-01)The N2 laser excited fluorescence spectrum and the intensity of fluorescence of oxalyl chloride C2O2Cl2) condensed at 77°K either alone, or, diluted with a non-hydrocarbon or a hydrocarbon with dilution ratios ranging from ...
-
(Taylor & Francis Group, 1984-01-01)Nitrogen laser induced two photon ionization spectrometric (TPIS) signals were detected with a simple dc current detector (picoammeter), of which the detection power is nearly the same as with a boxcar peak-gated detection ...
-
(Taylor & Francis Group, 1994-09-01)Monte Carlo simulations were undertaken of the orientational herringbone phase transition of N2 adsorbed on graphite in the complete monolayer (✓3 × ✓3) R30° structure. The non-universal aspects (concentrating here on the ...
-
(Taylor & Francis Group, 1986-03-01)The large liquid scintillator method has been used to measure the 239Pu(n,2n) cross section between threshold and 13 MeV, and the 2H(n,2n) cross section between 7.5 and 15 MeV. The 239Pu excitation function has been ...
-
(Taylor & Francis Group, 1996-01-01)N2-(p-n-Octylphenyl)-2′-deoxyguanosine 5′-triphosphate (OctPdGTP)has been synthesized chemically. OctPdGTP inhibited DNA polymerases (pol) α, δ and ε from calf thymus, with moderate selectivity for pol α. Mechanistic studies ...

-
(Taylor & Francis Group, 1983-07-01)
-
(Taylor & Francis Group, 1991-10-01)Several N2-alkyl and N2-phenyl 2′-deoxyguanosine 5′-triphosphates and 2-bromo-2′-deoxyinosine 5′-triphosphate were synthesized and tested as substrates for E. coli DNA polymerase I with a template: primer system requiring ...
-
(Taylor & Francis Group, 1982-01-01)Phase-transfer catalysis of pyrrolo[2,3-d]pyrimidine 4a with the halogenose 5 yields the anomers 6a and 7a. Deprotection with boron trichloride gives the chloro nucleosides 6b and 7b, which are converted into the potential ...
-
(Taylor & Francis Group, 1973-01-01)This paper constitutes a preliminary report of the existence of a hitherto unrecorded Bushman language of Botswana and attempts to establish its lexical relationships to the other so‐called Bushman‐Hottentot languages.
-
(Taylor & Francis Group, 1993-12-01)A series of dialkylformamidine protected deoxyadenosine phosphoramidites were prepared for automated, solid-support DNA synthesis. The set of Abz, Gdmf, Cbz, T phosphoramidites gave high purity and high yield oligodeoxyn ...
-
(Taylor & Francis Group, 1984-08-01)Groups of “Kallar”; grass plants were subjected to various treatments of 100 mM NaCl simultaneously labelled with 22Na+ and 36Cl−. On the basis of the specific activity, the distribution of Na and Cl− in the tissue was ...
-
(Taylor & Francis Group, 1991-11-01)We have undertaken a fundamental study of heterodiffusion of foreign ions in pure single crystals. The present work describes the measurements of the diffusion coefficient of monovalent cations in some alkali halides, ...
