1. Volatile Constituents of Floral Scents from Encyclia cordigera (Kunth) Dressler and E. randii (Barb. Rodr.) Porto & Brade (Orchidaceae)
Encyclia cordigera is native from Central America tropical region, and Encyclia randii occurs at Brazilian Amazon environment domains. Floral concentrates from both Encyclia species were extracted, analyzed by gas chromatography-mass spectrometry, and identified compounds belong to terpenoids, phenylpropanoids, and fatty acid derivatives classes. Primary con

3. Food production potential of Favolus brasiliensis (Basidiomycota: Polyporaceae), an indigenous food
Abstract The Amazon region has shown commercial potential for native mushroom species, such as mushrooms produced by the Yanomami people, who already sell more than 10 Amazon species. Among the species collected and consumed by the Yanomami people is Favolus brasiliensis (Fr.) Fr. (Basidiomycota: Polyporaceae), which occurs naturally in tropical areas of Cen

4. Assessment of Total Attenuation and Adaptive Scheme for Quality of Service Enhancement in Tropical Weather for Satellite Networks and 5G Applications in Nigeria
Abstract The dynamic weather condition is a major concern for optimum channel utilization in recent times, especially at higher frequencies with larger bandwidth for 5G applications. Over the years, rain-induced attenuation among the hydrometeors has been linked as the major cause of signal impairment especially at the frequency, f ≥ 10 GHz. However, when

5. Photosynthesis, growth, and survival in seedlings of four tropical fruit-tree species under intense radiation
RESUMEN En la región amazónica, los sistemas agroforestales (SAFs) se recomiendan como una alternativa de producción sustentable para las comunidades locales. Un componente común en los SAFs amazónicos son los árboles frutales tropicales, que pueden formar parte del dosel o crecer en el sotobosque. En este trabajo, estudiamos el efecto de la radiación

6. Implementation of ventilation towers in a greenhouse established in low altitude tropical climate conditions: numerical approach to the behavior of the natural ventilation
ABSTRACT Deficient ventilation rates and airflow patterns in naturally ventilated greenhouses are the main causes for the generation of inadequate and heterogeneous thermal conditions inside this type of structure. In this research, a numerical study was developed using a two-dimensional computational fluid dynamics model validated in a Colombian greenhouse

7. CHARACTERIZATION OF AQUATIC ORGANIC MATTER IN A NATURAL ENVIRONMENT IN NORTHEASTERN BRAZIL
The organic matter (OM) contained in a natural aquatic environment, located in a tropical region in Notheastern Brazil, was characterized using synchronous fluorescence spectroscopy and UV-Vis absorbance. The synchronous fluorescence spectra did not show qualitative differences for samples collected during dry and rainy seasons. They also revealed two peaks,

10. Effects of Oral Oxytetracycline-Therapy on Wound Progression and Healing Following Aeromonas caviae Infection in Nile Tilapia (Oreochromis niloticus L.)
Abstract The effects of oral oxytetracycline (OTC)-therapy against Aeromonas caviae infection as well as the wound progression and healing in intramuscular (IM) and abrasion-immersion (AI) challenged Nile tilapia juveniles were evaluated. The IM challenge caused significantly (p < 0.05) high mortalities (90%) compared to AI challenge (40%). The mortalities r
