Atmospheric brown carbon (BrC) is a significant contributor to light absorption and climate forcing. However, little is known about a fundamental relationship between the chemical composition of BrC and its optical properties. In this work, light-absorbing secondary organic aerosol (SOA) was generated in the PNNL chamber from toluene photo-oxidation in the presence of NOx (Tol-SOA). Molecular s...

The focus of this paper is to construct daily time series exchange rate forecast models of Samoan Tala/USD and Tala/AUD during the year 2008 to 2012 with neural network The performance of the models was measured by using varies error functions such as Root Square mean error (RSME), Mean absolute error (MAE), and Mean absolute percentage error (MAPE). Our empirical findings suggest that AR (1) m...

During years 2012 to 2018, two fish species, doublespotted queenfish ( Scomberoides lysan) and sixbar angelfish Pomacanthus sextriatus ) were regularly examined during filleting processing in markets at Jubail province, Saudi Arabia. The routine inspection of the fillet- by products (fish skeletons) these species showed prominent frequent hard circumscribed ossified masses attached spines. In l...

The family Cynodontidae is composed of freshwater fishes inhabiting drainages east the Andes in South America. Its fossil record mostly represented by isolated teeth that are difficult to identify. Here we describe cranial remains extant species Hydrolycus scomberoides as well were identified and cf. Rhaphiodon sediments late Pliocene Ware Formation Guajira Peninsula, west Andes. Novel, phyloge...

Abstract Phylogenetic proximity suggests some degree of diet similarity among species. Usually, studies show that species coexistence is allowed by partitioning food resources. We evaluate how visually oriented piscivorous fishes (Characiformes) share prey before and after building the Santo Antônio Hydroelectric Power Plant (HPP) in Madeira River (Brazil), largest muddy-water tributary Amazon ...

Talang Queenfish (Scomberoides commersonnianuus) is relatively inexpensive fish with low consumption in Fars Province, South of Iran. In this research which was done in 2011, minced fish sausages were produced from mince and surimi of this species and some physicochemical attributes of the products were investigated during 60 days of cold storage at 4 °C. According to the results, free fatty ac...
