2. Bioactivity of essential oils from Artemisia against Diaphania hyalinata and its selectivity to beneficial insects

ABSTRACT: The demand for effective insecticides in pest control with low toxicity to the non-target organisms, such as natural enemies and pollinators, is increasing steadily. A good alternative for synthetic insecticides is natural compounds, including essential oils (EO). This work assessed toxicity of essential oils extracted from Artemisia annua, A. absi

3. Pina Bausch en Brasil: fruta, vestidos, felicidad y Água

Abstract: This article approaches the work of Pina Bausch and the creative processes of the Tanztheater Wuppertal Company. The focus is on the work developed during her residencies in several cities around the world, a cartographic repertoire that provides a trans-border and trans-modern historical perspective from the stage. Through the analysis of several

4. Good Manufacturing Practices, Hazard Analysis and Critical Control Point plan proposal for distilleries of cachaça

ABSTRACT: Cachaça poses many quality (appearance, taste, consumer acceptability) and safety hazards (chemical, metal, and microbiological contaminations during the process). In this work, an effort is made for the quality and safety analysis of cachaça, by describing and outlining the potential hazards in every step of the process. This study revealed that

5. Abscisic acid and ethephon treatments applied to ‘Verdejo’ white grapes affect the quality of wine in different ways

ABSTRACT: Exogenous ethephon and abscisic acid (ABA) treatments are used worldwide to improve the coloring of red table grapes, but there is little information about their impact on the quality of white grapes and wines. The aim of this work was to evaluate the effects of exogenous ethephon and ABA applications at veraison on the composition of ‘Verdejo’

6. Bacterial communities in mining soils and surrounding areas under regeneration process in a former ore mine

Abstract Human activities on the Earth's surface change the landscape of natural ecosystems. Mining practices are one of the most severe human activities, drastically altering the chemical, physical and biological properties of the soil environment. Bacterial communities in soil play an important role in the maintenance of ecological relationships. This work

7. The Influence of Microstructure and Mechanical Resistance on the Shape Memory of Ecae Processed Stainless Fe-Mn-Si-Cr-Ni-Co Steel

In the current work, XRD, SEM, EBSD and TEM techniques were used to evaluate the microstructure of stainless Fe-Mn-Si-Cr-Ni-Co shape memory steel processed by ECAE and annealed for one hour at temperatures ranging from 650ºC to 950ºC. The results were then correlated with the mechanical and shape-memory properties of the steel. It was observed that the sam

8. Analysis of β´(Cu4Ti) Precipitation During Isothermal Aging of a Cu-4wt.%Ti Alloy

This work analyzed experimental and numerically the growth kinetics of β´precipitation of a Cu-4wt.%Ti alloy after aging at 400, 500 and 600 ºC for times from 0.0166 h to 200 h. Results indicated that the precipitation process is almost controlled by nucleation and growth during aging at 400 ºC, originating a slow growth kinetics of precipitation. In con

9. Carcinoid syndrome: update on the pathophysiology and treatment

Approximately 30-40% of patients with well-differentiated neuroendocrine tumors present with carcinoid syndrome, which is a paraneoplastic syndrome associated with the secretion of several humoral factors. Carcinoid syndrome significantly and negatively affects patients’ quality of life; increases costs compared with the costs of nonfunctioning neuroendocr

11. Novel Artificial Ornamental Stone Developed with Quarry Waste in Epoxy Composite

Ornamental stones, such as marble and granite, are worldwide used as pavement cover and lining parts in civil construction. Dwindling deposits and environmental pollution, due to extraction methods, have motivated the replacement of natural ornamental stones by synthetic ones. In particular, artificial ornamental stones are being developed with mineral waste

12. The Formation and Dynamic Evolution of Antiphase Domain Boundary in FeAl Alloy: Computational Simulation in Atomic Scale

The main objective of the present work is to build a model and analyze the dynamic evolution process of antiphase domain boundary (APDB) in FeAl alloy. The formation, evolution of APDB, long range order (LRO), the crystal structure transition, impact of temperature on LRO, are investigated. Comparisons with experiments proves that the model is competent for
