It detects people in the surroundings and manipulates the robot’s motions to approach them keeping an acceptabl...

Hyphenating High Temperature High Performance Liquid Chromatography (HT-HPLC) with High Temperature Size Exclusion Chromatography (HT-SEC) (High Temperature Two Dimensional Liquid Chromatography (HT-HPLC x HT-SEC or HT 2D-LC)) leads to an isocratic elution in the second dimension, which in turn enables to use IR detector (quantitative detection) for monitoring the eluting polymers. Experimental...

One hour after a bone marrow biopsy and inhalation of Entonox gas (50% nitrous oxide (N2O) and 50% oxygen), a patient had a markedly reduced transfer factor of the lung for carbon monoxide (TL,CO). Three hours after Entonox, the patient had a normal TL,CO. Since carbon monoxide (CO) and N2O have similar spectral wavelengths, it was proposed that residual N2O in the lungs was interfering with th...

Abstract One of the characteristics Ganoderma disease is that it asymptomatic, visual symptoms appear when condition plant severe so early detection and identification become a fundamental problem. This study aims to identify by analyzing vegetation index NDVI, GNDVI, SAVI based on reflectance value oil palm images recorded with UAV vehicle equipped multispectral sensor 3 bands red (Red), green...

A simple reaction process is developed to synthesize blue, green, yellow and red colour graphene nanoparticles (GNPs) from carbon fibers. Here, we have focused on synthesis of near infra-red GNPs and their biological application for optical imaging of deep tissues and organs.
