There is considerable intraspecific variation in metabolic rates and locomotor performance in aquatic ectothermic vertebrates; however, the mechanistic basis remains poorly understood. Using pregnant Trinidadian guppies (Poecilia reticulata), a live-bearing teleost, we examined the effects of reproductive traits, pectoral fin use and burst-assisted swimming on swimming metabolic rate, standard ...

With petroleum exploration and development expanding in the Arctic (AMAP, 2007) there is a need to obtain additional information on the ecotoxicology of Arctic organisms. Here we perform 192 h laboratory exposure experiments on the keystone Arctic zooplankton species, Calanus finmarchicus. We trace the accumulation and depuration of two polycyclic aromatic hydrocarbons (PAHs): phenanthrene and ...

Title of Thesis: MODELING OF INTERFACES: APPLICATIONS IN SURFACE AND POLYMER PHYSICS Paul Patrone, Doctor of Philosophy, 2013 Dissertation directed by: Professor Theodore L. Einstein Department of Physics In this dissertation, I give an overview of my work on multiscale modeling of interfaces in crystalline and block-copolymer systems. I focus on two distinct interface systems: steps on vicinal...

Water pollution is one of the global challenges that society must address in 21st century aiming to improve water quality, reduce human pollutants and ecosystem health impacts. In phytotoxicity test, plant Iresine herbstii was exposed remove nickel from simulated wastewater using two different ratios (mass mass nickel) (,Rp/Ni) for 21 days with sub-surface batch system. During exposure period, ...


 Acid mine drainage is mining waste that contains a lot of sulfate and heavy metals such as Fe Mn which can cause environmental damage pollute the ecosystem, therefore it needs to be managed. One way manage acid with phytoremediation techniques using Purun tikus (Eleocharis dulcis). The ability accumulate known by calculating bio-concentration factor (BCF) tranclocation (TF). This study a...

A potted experiment was conducted to explore the accumulation of arsenic (As) and predict uptake As by a wheat-maize rotation system in calcareous soil with different rates sewage sludge (SS) amendment over two consecutive years. The SS decreased pH value but increased cation exchange capacity (CEC), calcium carbonate (CC), organic carbon (OC) crops increasing addition. bioconcentration factor ...

Abstract The toxicokinetic (TK) model‐derived kinetic bioconcentration factor (BCF k ) provides a quantitatively comparable index to estimate the bioaccumulation potential of nanoparticles (NPs) that barely reach thermodynamic equilibrium in aquatic organisms, but experimental data are limited for various NPs. In present study, machine learning model was applied offer reliable silico prediction...

This paper proposes a novel bacterial colony foraging (BCF) algorithm for complex optimization problems. The proposed BCF extend original bacterial foraging algorithm to adaptive and cooperative mode by combining bacterial chemotaxis, cell-to-cell communication, and a self-adaptive foraging strategy. The cell-to-cell communication enables the historical search experience sharing among the bacte...

Design and Implementation of a Biomimetic Robotic Fish Hongan Wang The study of biomimetic robotic fish has received a growing amount of research interest in the past several years. This thesis describes the development and testing of a novel mechanical design of a biomimetic robotic fish. The robotic fish has a structure which uses oscillating caudal fins and a pair of pectoral fins to generat...
