Optimization of semiochemical-based trapping of Metamasius hemipterus sericeus (Olivier) (Coleoptera: Curculionidae)
(1996-08)
Response of adults of the West Indian sugarcane weevil,Metamasius hemipterus sericeus, to various semiochemical treatments and physical trap designs was studied in southern Florida in field-grown banana and Canary Island ...
Synthesis and Crystal Structure of a Copper(II) Benzoate Complex Bearing a Bis-2,2′-Tetrahydrofuryl Peroxide Moiety
(2018-12)
Complex [Cu2(ben)4·2THF−(η1–O2)]∞ (2) (ben=C6H5CO2− benzoate; THF=tetrahydrofuran) was isolated when a solution of Cu2(ben)4·2THF (1) in THF upon natural sunlight irradiation yields crystals suitable for single-crystal ...
Expanding the Trichoderma harzianum species complex: Three new species from Argentine natural and cultivated ecosystems
(2021-06-22)
A study was performed on a collection of 84 isolates from decaying plant tissues and soils in
Argentina previously identified as Trichoderma harzianum. Based on multiple phenotypic characters
and multilocus phylogenetic ...
Evaluación de la capacidad del cemento Portland dopado con nanopartículas de TIO2 para la disminución de Pseudomonas aeruginosa y Escherichia coli en agua
(2022-10)
El abastecimiento de agua potable no es equitativo para la población mundial y este problema empeora debido al crecimiento poblacional, a la contaminación, al calentamiento global y a un inadecuado tratamiento de potabilización. ...

Reactivity and structure of derivatives of 2-hydroxy-1,4-naphthoquinone (lawsone)
(2007-11)
The structures of two derivatives of 2-hydroxy-1,4-naphthoquinone (lawsone) are examined using the density functional theory (DFT) hybrid functional B3LYP. Using the optimized structure of lawsone acetate, the reactivity ...
Room temperature gas-solid reaction of titanium on glass surfaces forming a very low resistivity layer
(2016-09)
Titanium films were deposited on quartz, glass, polyamide and PET substrates in a high vacuum system at room temperature and their electrical resistance monitored in vacuo as a function of thickness. These measurements ...
Seco-manool and other constituents from fleischmannia microstemon
(1988-01)
The aerial parts of Fleischmannia microstemon afforded in addition to sesamin and two clerodanes, ent-manoyl oxide and two derivatives of the latter, one a 6β-acetoxy derivative and the other a seco-labdane. From F. pratensis ...
Differential volatile organic compound expression in the interaction of Daldinia eschscholtzii and Mycena citricolor
(2023)
Fungi exhibit a wide range of ecological guilds, but those that live within the inner
tissues of plants (a.k.a. endophytes) are particularly relevant due to the benefits they
sometimes provide to their hosts, such as ...
Fate of buturon-14C in soil during seven seasons of exposure under outdoor conditions
(1984-03)
Buturon (ring 14C) was applied to wheat and soil in two successive years (3 kg/ha each year) at outdoor conditions. Residual radioactive substances in the upper soil layer (0-10-cm depth) were measured 1.5, 2.5, 3.5, 6.0, ...
