Spatial Variability Of Eucalyptus Dendrometric Properties And Chemical Attributes Of A Quartzarenic Neosol
(Univ Estadual Mato Grosso do SulDourados, 2017)
Females of the four-eyed frog, pleurodema thaul (Anura, Leptodactylidae), respond behaviourally to conspecific male scent
(Pensoft, 2021)
Among amphibians, conspecific chemical communication has been widely studied in Caudata. Adult anurans, by contrast, have received less attention. Recently, it was shown that chemical scents are also relevant for adult ...
Preliminary assessment of the quantitative relationships between testicular tissue composition and ultrasonographic image attributes in the ram
(2013-07-11)
This study examined the relationships between gross chemical composition and ultrasonographic characteristics of the ram testes. Ten testes from sexually mature Karakul rams were scanned ex situ with an 8-MHz linear-array ...
Yield and mineral nutrition of soybean, maize, and congo signal grass as affected by limestone and slag
(2013-10-10)
The objective of this work was to evaluate the efficiency of superficial applicationof limestone and slag, and their effects on soil chemical attributes and on yield and mineral nutrition of soybean, maize, and Congo signal ...
Plantas de cobertura em pré-safra e adubação nitrogenada na fertilidade do solo em diferentes camadas, cultivado com milho em sistema de plantio direto e convencional
(Universidade Estadual de Londrina (UEL), 2012-01-01)
The species of cover crops in pre-harvest of maize crop may influence the soil chemical properties. The objective was to evaluate soil fertility due to the use of plant species cover, previously cultivated with maize crop ...
Yield, yield components, soil fertility, and nutritional status of soybean as influenced by limestone and copper interactions
(Taylor & Francis Inc, 2020-06-25)
Continuous limestone application can inhibit the copper (Cu) uptake by plants. This experiment was carried out in greenhouse conditions using two soils (Typic Oxisol and Typic Entisol) with different clay and soil organic ...
APPLICATION EFFECT OF DIFFERENT RATES OF WASTEWATER FROM GELATIN PRODUCTION IN THE CHEMICAL ATTRIBUTES OF THE SOIL
(Associação Brasileira de Engenharia Agrícola, 2018)
The gelatin industry wastewater has nutrients in its composition, allowing its use in agriculture as an alternative to disposal and recycling of this residue. However, high application rates can cause the accumulation of ...
Molecular interactions from the density functional theory for chemical reactivity: the interaction energy between two-reagents
(Frontiers Media, 2022)
Reactivity descriptors indicate where a reagent is most reactive and how it is most likely to react. However, a reaction will only occur when the reagent encounters a suitable reaction partner. Determining whether a pair ...
Electroluminescence of zinc oxide thin-films prepared via polymeric precursor and via sol-gel methods
(Elsevier B.V., 2007-12-03)
Zinc oxide (ZnO) is an electroluminescent (EL) material that can emit light in different regions of electromagnetic spectrum when electrically excited. Since ZnO is chemically stable, inexpensive and environmentally friendly ...
