1. Characterization of tomato generations according to a three-way data analysis
ABSTRACT Availability of a three-way data analysis to characterize two consecutive tomato (Solanum lycopersicum) generations is necessary to continue a plant breeding program with less uncertainty. The aim of this work was to analyze tomato fruit quality from F2 and F3 populations by two three-way data analysis: multiple factorial analysis (MFA) and generali

2. Strength analysis of composite cables
Abstract Carbon Fiber Reinforced Polymer (CFRP) cables, due to their outstanding performance in terms of specific stiffness and strength, are usually found in civil construction applications and, more recently, in the Oil & Gas sector. However, experimental data and theoretical solutions for these cables are very limited. On the contrary, several theoretica

3. Measurement uncertainty of dissolution test of acetaminophen immediate release tablets using Monte Carlo simulations
ABSTRACT Analytical results are widely used to assess batch-by-batch conformity, pharmaceutical equivalence, as well as in the development of drug products. Despite this, few papers describing the measurement uncertainty estimation associated with these results were found in the literature. Here, we described a simple procedure used for estimating measuremen

8. Reliability-based evaluation of design guidelines for cold-formed steel-concrete composite beams
This paper presents an analysis of design guidelines for steel-concrete composite beams, formed by concrete-filled cold-formed steel sections. The study is based on experimental results for connector resistance (push-out) and for four full-scale beam bending tests. The accuracy of analytical design equations is evaluated by comparing their predictions with e

10. Estimativa da incerteza de medição em análise cromatográfica: abordagem sobre a quantificação de carbamato de etila em cachaça
The measurement uncertainty is useful to estimate the confidence of analytical results. Nowadays, a result without the uncertainty statement cannot be considered reliable, but the scientific literature still lacks examples of the estimate of the measurement uncertainty. This paper presents a practical and reliable description of the measurement uncertainty e

12. DESENVOLVIMENTO DE MÉTODOS ANALÍTICOS ESPECTROLUMINESCENTES E ELETROFORÉTICOS PARA A DETERMINAÇÃO DE ALCALOIDES (BETA-CARBOLINAS, CAMPTOTECINA E DERIVADOS) DE INTERESSE FARMACOLÓGICO / DEVELOPMENT OF ANALYTICAL METHODS BASED ON LUMINESCENCE AND ELECTROPHORESIS FOR THE DETERMINATION OF ALKALOIDS (BETA-CARBOLINES, CAMPTOTHECIN AND DERIVATIVES) OF PHARMACOLOGICAL INTEREST
Analytical methods were developed for the selective determination of alkaloids of pharmacological interest. Aiming the selective determination of camptothecin (CPT) in irinotecan (CPT-11) or topotecan (TPT) based pharmaceutical formulations, two spectrofluorimetric methods and one electrophoretic method with absorciometic detection were proposed. The spectro
