COMPOUND SPECKLE REDUCTION IN LASER IMAGING SYSTEMS BY USING A VIBRATING MULTIMODE FIBER AND A TRACKED MOVING FLEXIBLE DOE LOOP

Compound Speckle Reduction in Laser Imaging Systems by Using a Vibrating Multimode Fiber and a Tracked Moving Flexible DOE Loop

The speckle phenomenon produced by coherent waves interfering with each other is undesirable in laser imaging systems.For each of the laser speckle reduction methods in the literature, it is difficult to reduce speckle to an extremely low level (< 3%) and also ensure good Nipple Covers image quality.Therefore, a compound speckle reduc

The effects of coloniality and international development assistance on Made in Africa Evaluation: Implications for a decolonised evaluation agenda

Background: It is imperative to recognise the effects of the intrinsically Eurocentric development agenda on attaining transformative evaluation that appropriately addresses development priorities in Africa.The role of international development agencies as critical anchors in African evaluation practice needs examination to advance the Made in Afri

C-banding and fluorescent in situ hybridization with rDNA sequences in chromosomes of Cycloneda sanguinea Linnaeus (Coleoptera, Coccinellidae)

The aim of this study was to describe mitotic and meiotic chromosomes of Cycloneda sanguinea using C-banding, fluorescent in situ hybridization (FISH) rDNA probes, and sequential FISH/Ag-NOR staining.The chromosome number was 2n = 18 + XX for females and 2n = 18 + Xy for males.The X chromosome was metacentric and the Y chromosome was very small.Dur

Dopaminergic Neuromodulation of Spike Timing Dependent Plasticity in Mature Adult Rodent and Human Cortical Neurons

Synapses in the cerebral cortex constantly change and this dynamic property regulated by the action of neuromodulators such as dopamine (DA), is essential for reward learning and memory.DA modulates spike-timing-dependent plasticity (STDP), a cellular model of learning and memory, in juvenile rodent cortical neurons.However, it is unknown whether t
