We study 3-dimensional Ricci solitons which project via a semi-conformal mapping to a surface. We reformulate the equations in terms of parameters of the map; this enables us to give an ansatz for constructing solitons in terms of data on the surface. A complete description of the soliton structures on all the 3-dimensional geometries is given, in particular, non-gradient solitons are found on ...

Nanoimprint lithography (NIL) has been successfully employed in nanoscale patterning, however, it is known to have limitations in replicating large-scale (hundreds of microns and larger) and nanoscale patterns simultaneously. In this letter, we present a novel lithographic technique that integrates photolithography into the NIL patterning process. This technique uses a hybrid mask-mold that has...

Nanoimprint lithography ~NIL! is a paradigm-shift method that has shown sub-10-nm resolution, high throughput, and low cost. To make NIL a next-generation lithography tool to replace conventional lithography, one must demonstrate the needed overlay accuracy in multilayer NIL, large-area uniformity, and low defect density. Here, we present the fabrication of 60-nm channel metal–oxide–semiconduct...

-Melanocyte–stimulating hormone ( -MSH) is a natriuretic peptide derived from proopiomelanocortin (POMC) in the pituitary neurointermediate lobe (NIL); its plasma concentration in rats doubles after ingestion of a high (HSD; 8% NaCl) compared with a low sodium diet (LSD; 0.07%). Because NIL function is regulated through dopaminergic pathways, we asked whether dopaminergic stimulation with bromo...

The mineralisation kinetics of petroleum refinery effluent (PRE) by Fenton oxidation were evaluated. Within the ambit of the experimental data generated, first-order kinetic model (FKM), generalised lumped kinetic model (GLKM), and generalized kinetic model (GKM) were tested. The obtained apparent kinetic rate constants for the initial oxidation step (k'2), their final oxidation step (k'1), and...

Diabetes mellitus, a metabolic disorder, is characterized by hyperglycemia and altered metabolism. The administration of D-Nil plus (a polyherbal drug) showed effective treatment for alloxan induced diabetes in rats. In diabetic rats, haematological profiles namely RBC, WBC, platlet count and haemoglobin were decreased whereas ESR was increased. Similarly biochemical parameters creatinine, urea...

A new low-cost, high throughput method was developed for fabricating large area quantized magnetic disks ~QMDs! using nanoimprint lithography ~NIL!, electroplating, and chemical mechanical polishing. Perpendicular QMDs with a density of 18 Gbit/in. and good uniformity over an area of 4 cm34 cm ~total 45 Gbit! have been achieved, as well as longitudinal QMDs of 30 Gbit/in. The NIL molds for the ...
