Trace metals concentration and proximate composition of raw and boiled silver pomfret (Pampus argenteus) from coastal area and retail market were determined to gain the knowledge of the risk and benefits associated with indiscriminate consumption of marine fishes. The effects of cooking (boiling) on trace metal and proximate composition of silver pomfret fish were also investigated. Trace eleme...
A arte rupestre representa um importante patrimônio arqueológico, no entanto, devido à exposição ao ar livre, apresenta uma série de problemas que afetam a sua integridade. Considerando isso, utilizamos ferramentas arqueométricas não destrutivas fim conhecer os principais agentes causadores da degradação e dos componentes das tintas pretéritas do sítio Morro Letreiro, localizado município Palme...
This study presents the numerical simulation, optimization, preparation, and characterization of Cu(In, Ga)Se2 (CIGS) thin-film solar cells (TFSCs). Different cell parameters were investigated, including Ga/(Ga+In) (GGI) ratios, thicknesses CIGS absorption layers, fill factor (FF), open-circuit voltage (Voc), short-circuit current (Isc). The effects simulated on power conversion efficiency (η) ...
