Background: Persistent oral administration of Amaranthus extract could decrease contractile response and enhance relaxation response in aortic tissue of diabetic rat through affecting endothelial related agents. This may be beneficial in prevention of long-term vascular complications of diabetes. Materials and Methods: In this exprimental study, Amaranthus caudatus rats (160-220 g) were used in...

Understanding physical configurations and how these can emerge from the underlying gauge theory is a fundamental problem in modern particle physics. This thesis investigates the study of these configurations primarily focussing on the need for gauge invariance in constructing the gauge invariant fields for any physical theory. We consider Wu’s approach to gauge invariance by identifying the gau...

Over the last decade attempts have been made to fabricate aluminum matrix composites (AMCs) reinforced with several ceramic particles. Aluminum reinforced with ZrB2 particles is one such AMC. The successful application of new kind of AMCs lies in the development of secondary processes such as machining and joining. Friction stir welding (FSW) is a relatively new solid state welding which overco...

Many plants exude allelochemicals--compounds that affect the growth of neighbouring plants. This study reports further studies of the reported effect of cress (Lepidium sativum) seed(ling) exudates on seedling growth in Amaranthus caudatus and Lactuca sativa. In the presence of live cress seedlings, both species grew longer hypocotyls and shorter roots than cress-free controls. The effects of c...

Amaranthus caudatus is a nutrient-rich Andean pseudocereal with wide genetic variability. Six productive varieties (Oscar Blanco, Pucara, Tomina, Cotahuasi, Barbechos, and Guindo Criollo) were compared by proximate, mineral, fatty acid composition. The proximal content showed certain singularities in the varieties. Barbechos Criollo stood out for their fat (9.50% 9.01%, respectively), while Tom...

A multiply-lensed galaxy, MACS0647-JD, with a probable photometric redshift of z ' 10.7 −0.4 is claimed to constitute one of the very earliest known galaxies, formed well before reionization was completed. However, spectral evidence that MACS0647-JD lies at high redshift has proven infeasible and so here we seek an independent lensing based “geometric redshift” derived from the angles between t...
