Effectiveness of the compound Chlorpyrifos+Cypermethrin+Citronellal against Alphitobius diaperinus. Laboratory analysis and residue determination in carcasses
(2007-01-01)
Effectiveness, biological security and the absence of residues in meat and/or eggs must be considered when recommending options for the control Alphitobius diaperinus in poultry production environments. This research study ...
Veterinary Drug Residues in Meat-Related Edible Tissues
(Elsevier, 2017)
Veterinary drugs are chemicals used to control diseases in animals. If good veterinary practices are followed, these drugs are very useful and make it possible to obtain excellent and abundant food production. In order to ...
Effect of residual stresses and inclusion size on fatigue resistance of parabollic steel springs
(Carl Hanser Verlag, 2014-04-08)
The effect of inclusion size and residual stresses of spring steel grade 51CrV4 on fatigue lifetime in high cycle was investigated by experimental results obtained by fatigue testing. Since spring with obvious surface ...
Influential factors affecting inherent deformation during plate forming by line hating (Report 1) - the effect of plate size and edge effect
(2007-09)
The authors aim to propose an accurate and practical method to predict the deformation of actual plates of large size such as those used in shipbuilding. This method is to be used to improve the accuracy of an automatic ...
For how long does the quality and quantity of residues in the soil affect the carbon compartments and CO2-C emissions?
(2016-10-01)
Purpose: The mineralization/immobilization of nutrients from the crop residues is correlated with the quality of the plant material and carbon compartments in the recalcitrant and labile soil fractions. The objective of ...
The effect of process parameters and cutting tool shape on residual stress of SAE 52100 hard turned steel by high speed machining
(2020-04-26)
This study focused on determining the residual stress of SAE 52100 hard-turned steel. The objective was to evaluate and compare the effects of the cutting-edge geometry and cutting parameters (cutting speed, feed rate, and ...
Residual influence of nitrogen, phosphorus and potassium doses on soil and eucalyptus nutrition in coppice
(2021-10-01)
The management of fertilizer is an important strategy for better nutrition and productivity of eucalyptus. Therefore, the objective of this research was to evaluate the isolated residual effect (carryover) of N, P and K ...
Dinâmica do carbono influenciada pela qualidade de resíduos culturais, teor inicial de carbono e textura em dois solos subtropicais
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em Ciência do SoloCentro de Ciências Rurais, 2020-02-28)
Crop residues quality and initial soil carbon (C) content influence the residue-derived C
dynamic in agricultural soils. However, there is a limited understanding about the fate of residue
C and the net C balance in the ...
Shear wave propagation in residual soil–rigid inclusion mixtures
(Elsevier Science Sa, 2019-02)
Residual and tropical soils are particulate materialswith a wide range of particle sizes. Usually these geomaterials have a fine particle matrix containing dispersed rigid inclusions that affect theirmechanical behavior. ...
