13. PARAMETERS FOR MODELING PASSIVE SUSPENSIONS OF SPRAY BARS
ABSTRACT The uniformity and quality of spraying depend on the stability of the spray boom, defined as the suspension system between the boom and the machine chassis. This paper presents a procedure for improving the performance of passive spray bar suspensions through parameter adjustment. Two multibody dynamics models of a tractor sprayer set were developed

14. Adult Perfomance on the Sustained Auditory Attention Skill Test
Abstract Introduction The Sustained Auditory Attention Ability Test (SAAAT) is an instrument used to assess sustained auditory attention in children. Difficulties related to this ability are not unique to children alone, as adults have been observed to present with the same deficits. Therefore, there is a need to adapt instruments like the SAAAT and provide

15. Is serum PSA a predictor of male hypogonadism? Testing the hypothesis
ABSTRACT Objective: Male hypogonadism (MH) is common among infertile men. Besides testosterone, limited MH biomarkers are available, while researchers have suggested the use of prostate-specific antigen (PSA) to help diagnose MH. Hence, we sought to evaluate the potential use of PSA to predict MH among relatively young men with infertility in Nigeria. Mate

17. Elevated Lipoprotein(A) in Children and Adolescents: Early Identification is Key for Successful Intervention
The usefulness of molecularly imprinted polymer assisted paper spray ionization mass spectrometry (MIP-PSI-MS) for the determination of methamphetamine in urine has been demonstrated. MIP-PSI-MS is a method in which a MIP is synthesized on the surface of a paper, producing a chemically selective paper surface with molecular recognition sites for a target ana

19. CARACTERIZAÇÃO E CONTROLE DE QUALIDADE DE ÓLEOS DE COPAÍBA (COPAIFERA SP.) UTILIZANDO DETECÇÃO DE MARCADORES POR FATOR DE RETENÇÃO RELATIVA EM HPTLC
Copaiba oilresins present medicinal uses that demand the development of methodologies that could ensure the authenticity and guarantee the species differentiation. The usual way to differentiate the copaiba oils is analyze the terpene composition, mainly the diterpenic acids profile. Unlike caryophyllene and its oxide, copaiba diterpenes are not commercially

20. Cost minimization analysis of an in-house molecular test for cytomegalovirus in relation to a commercial molecular system
ABSTRACT Introduction: Cytomegalovirus may cause severe disease in immunocompromised patients. Nowadays, quantitative polymerase chain reaction is the gold-standard for both diagnosis and monitoring of cytomegalovirus infection. Most of these assays use cytomegalovirus automated molecular kits which are expensive and therefore not an option for small labora

21. Simple GFAAS Method for Determination of Pb, As, and Cd in Cannabidiol Extracts Used for Therapeutic Purposes
Cannabis sativa has many promising medicinal applications for the mitigation, or even cure, of chronic diseases. The high bioaccumulation potential of C. sativa enables its use for the phytoremediation and detoxification of soil, may increase the levels of inorganic elements in products such as cannabidiol (CBD) extracts being necessary the evaluation/monito

23. Tri-ponderal mass index and body mass index in prediction of pediatric metabolic syndrome: the CASPIAN-V study
ABSTRACT Objective Body mass index (BMI) and tri-ponderal mass index (TMI) are anthropometric measures to evaluate body adiposity in the various age groups. The present study aims to compare the predictive value of TMI and BMI for metabolic syndrome (Mets) in children and adolescents of both genders. Subjects and methods A cross-sectional study conducted
