The Santos Basin (SB) is the main petroliferous basin in Brazilian continental margin and one of most studied marine areas Brazil. However, historical data suggest that new efforts should be carried out to acquire quantitative biological data, especially deep sea, establish baseline essential ocean variables different ecosystems for future monitoring programs. energy company Petrobras planned executed 24 oceanographic cruises over a period 2 years assess benthic (SANSED cruise) pelagic...
Abstract BACKGROUND This work aimed to prepare inclusion complexes using yellow bell pepper pigments and β ‐cyclodextrin by two different procedures (method A, ultrasonic homogenisation; method B, kneading), characterise them evaluate their colour stability in an isotonic beverage model. The extract/ ratio was 1:2 for both methodologies evaluated. formed extract– a physical mixture of extract were evaluated differential scanning calorimetry (DSC) Fourier transform infrared spectroscopy...
This study assessed the suitability of caffeine as an indicator for surface water pollution by domestic wastewaters. Caffeine concentrations determined in samples collected Paquequer River, located at city Teresópolis, a medium-sized State Rio de Janeiro, Brazil, were compared to other conventional quality parameters such phosphate, nitrate and ammonium determine whether it efficient anthropic urban aquatic environment. The River originates pristine area called Parque Nacional da Serra dos...
Natural within-thallus concentrations of elatol produced by Laurencia obtusa (Huds.) J. V. Lamour. inhibit herbivory and prevent fouling. However, occurs in larger amounts within the thallus compared with quantities from surface this alga. We evaluated whether both fouling content corps en cerise can be transferred to external cell walls. Surface did not sea urchins, settlement barnacle larvae, or mussel attachment. Evidence a connection between cerise, where is probably stored, wall L. was...

This article describes how Synchronous Ethernet technology provides a solution for transporting synchronization over Ethernet. uses syntonization/frequency from the physical layer together with slow protocol and has been standardized by ITUT frequency distribution. also could be extended in order to transport phase/time addition frequency; this is referred as "Time Ethernet" (TSE) article.
Brazilian citrus essential oils (mandarin, orange, lemon, bergamot and tangerine) were analyzed for the determination of pesticides residues organochlorine (aldrin, chlordane, dieldrin dicofol) organophosphorus (methyl chlorpyrifos, dimethoate, methidathion methyl parathion) . A comparative study between gas chromatography-mass spectrometry in selective ion monitoring mode (GC-MS-SIM) chromatography-electron capture detector (GC-ECD) was performed using solid phase extraction (SPE) with...
A specially designed high-pressure cell was used simultaneously as extractor/autoclave and photometric in a Perkin Elmer Lambda 5 spectrophotometer. Based on this cell, simple method developed to determine the extractability of pigments by pure modified supercritical (sc) CO2. The is demonstrated with curcumin from turmeric. With sc CO2 10% ethanol, extraction yield for two commercial finely ground dry turmeric samples about 100%, measured reference (complete) same charge ethanol under...
Synchronization has become key in many applications. It is a aspect of Industrial Automation networks, as those applications depend on synchronized time. also important for automotive applications, synchronization used infotainment and handling sensor data. In Telecommunications been years, it very to fulfill 5G technology requirements. The Time-Sensitive Networking (TSN) Task Group (TG) IEEE 802.1 developed several base standards allow deterministic network with bounded latency. Std AS,...
