Release of Nitrosamines and Nitrosamine Precursors from Scrap Tires | Environmental Science & Technology Letters
(American Chemical Society, 2021)
Materials used during manufacturing of tires can be a source of nitrosamines and/or their precursors. Here, we examined the leaching of nitrosamines and nitrosamine precursors from scrap tires under different test conditions. ...

Compounds of formula (I) or formula (II), compositions and methods useful for treating and/or preventing a fungal infections are provided. wherein the substituents are as defined in the appended claims.
The influence of temperature and pH on bacterial community composition of microbial mats in hot springs from Costa Rica
(2019)
We used the 16S rRNA gene pyrosequencing approach to investigate the microbial diversity and community composition in several Costa Rican hot springs alongside the latitudinal axis of the country, with a range of temperatures ...
Novel Cyanobacterial Diversity Found in Costa Rican Thermal Springs Associated with Rincon de la Vieja and Miravalles Volcanoes: A Polyphasic Approach
(2020)
Central America is one of the most important biodiversity hot spots in the world, and Costa Rican microbial communities from thermal springs are the best characterized in the isthmus. Miravalles is an inactive quaternary ...
Búsqueda y caracterización de proteínas biopesticidas novedosas a partir de cepas de Bacillus thuringiensis
(1999)
En la actualidad se desarrollan y se cultivan comercialmente plantas transgénicas que expresan endotoxinas de Bacillus thuringiensis (Bt) como biopesticida para el control específico de insectos. Sin embargo, se teme que ...
Thin-layer black phosphorus/GaAs heterojunction pn diodes
(2015)
Owing to its high carrier mobility and thickness-tunable direct band gap, black phosphorus emerges as a promising component of optoelectronic devices. Here, we evaluate the device characteristics of p-n heterojunction ...
C1 compounds shape the microbial community of an abandoned century-old oil exploration well
(2020)
The search for microorganisms that degrade hydrocarbons is highly relevant because it enables the bioremediation of these substances cheaply and without dangerous by-products. In this work, we studied the microbial communities ...
Mycelial inhibition of Trichoderma spp. (Hypocreaceae) isolated from the cultivation of Pleurotus ostreatus (Pleurotaceae) with an extract of Pycnoporus sp. (Polyporaceae)
Inhibición micelial de Trichoderma spp. (Hypocreaceae) aislado del cultivo de Pleurotus ostreatus (Pleurotaceae) con un extracto de Pycnoporus sp. (Polyporaceae)
(2020-01-07)
Background and Aims: The production of edible fungi is affected by bacterial, fungal and viral diseases, which very often cause large losses. In the production of mushrooms of the genus Pleurotus, the fungi of Trichoderma ...
The water striders (Hemiptera: Heteroptera: Gerridae) of Costa Rica: new species, checklist, and new records
(2018)
Brachymetra bernaldi Cordeiro, sp. nov. (Hemiptera: Heteroptera: Gerridae) from Heredia, Costa Rica, is herein described, illustrated, and compared with congeners. The new species resembles B. albinervus (Amyot & Serville, ...
Chapter 6: Founder variations in isolated populations
(2020)
Isolated populations, also called population isolates and genetic isolates, present several characteristic features that make them useful in the study of the genetic basis of both Mendelian and complex disorders. The ...
