Visible light driven photocatalytic oxidation of thiols to disulfides using iron phthalocyanine immobilized on graphene oxide as a catalyst under alkali free conditions
Download2020-01-28
Pawan Kumar, Garima Singh, Deependra Tripathi, Suman L Jain
The present paper describes the synthesis of graphene oxide immobilized iron phthalocyanine (FePc) for the photocatalytic oxidation of thiols to disulfides under alkaline free conditions. Iron phthalocyanine tetrasulfonamide was immobilized on carboxylated graphene oxide supports via covalent...

My intention in this paper is not to examine the conventions and techniques whereby biblical poetry is defined and ordered, but its capacity for subversion, its stylistic openness. The subject is the anti-poetic in poetry, its artlessness. The passages on which I focus may not perhaps be...

Vision-based Impedance Control of a 7-DOF Robotic Manipulator for Pick-and-Place Tasks in Grasping Fruits
Download2022-06-01
Chen, Qiguang, Wan, Lucas, Ravichadran, Prabahar, Pan, Ya-Jun, Chang, Young Ki
A vision-based impedance control method is applied to a 7-degree-of-freedom (7-DOF) Franka Emika (FE) Panda robotic manipulator to complete pick-and-place tasks with human-like grasping of fruits. The interfaces between different hardware and the controller are developed using robotic operating...

Chaudhry, Muhammad Salman, Czekanski, Aleksander
This work presents a methodology for the visual detection and robotic tracking of an uncooperative target. This article presents a closed-loop visual feedback-based control strategy combined with the Kalman filtering technique for autonomous tracking of the target object. The framework is based...

Visual pigment composition in zebrafish: Evidence for a rhodopsin-porphyropsin interchange system
Download2004
Temple, S. E., Allison, W. T., Haimberger, T. J., Hawryshyn, C. W.
Abstract: Numerous reports have concluded that zebrafish (Danio rerio) possesses A(1)-based visual pigments in their rod and cone photoreceptors. In the present study, we investigated the possibility that zebrafish have a paired visual pigment system. We measured the spectral absorption...

They may be a hot topic in health research and libraries, but infographics are not new. Information visualizations have a long history of use in medicine, particularly epidemiology. Now ubiquitous in modern urban landscapes, infographics are rebranded knowledge assemblages for an information age....

Visualization of dynein-dependent microtubule gliding at the cell cortex: implications for spindle positioning
Download2011
Dynein motors move along the microtubule (MT) lattice in a processive “walking” manner. In the one-cell Caenorhabditis elegans embryo, dynein is required for spindle-pulling forces during mitosis. Posteriorly directed spindle-pulling forces are higher than anteriorly directed forces, and this...

Vitamin D supplementation and bone health in adults with diabetic nephropathy: The protocol for a randomised controlled trial
Download2014
Hoffmann, Michelle R., Jindal, Kailash, Senior, Peter A., Mager, Diana R., Jackson, Stephanie T.
Background Suboptimal vitamin D status is highly prevalent in Northern communities, particularly in those patients with chronic diseases such as diabetes and chronic renal disease. Emerging literature suggests that adherence to daily vitamin D supplementation may be an important factor...
