Effect of flour protein content on the utilization of shortening and cellulose in biscuits
… and 0 or 2.2 grams of microcrystalline cellulose (MCC). Biscuit quality was assessed by objective and sensory evaluation. The caloric content of the biscuits was also determined by bomb calorimetry. No significant differences were detected in biscuit volume, crumb and crust color, or …

Development and Characterization of Intermediate-Band Quantum Wire Solar Cells
… the optical and electrical properties of solar cells are reported. To investigate the behavior of the intermediate band, the quantum wires were remotely doped at three different doping concentrations, the number of quantum wire layers was varied from three to twenty, and the solar cell structure …

Approaching Novel Perovskites Photovoltaic Devices through Machine Learning and Interfacial Engineering
… number of studies carried out, perovskite solar cell is still facing plenty of challenges towards commercialization. Two main challenges towards large-area commercialization include first the harsh fabrication environment and cost of large-area coating; and second the redundant fabrication …

Volumetric reconstruction of tissue structure from two-dimensional microscopy images
Cell morphology of tissue is naturally three-dimensional. Most current methods for tissue analysis use two dimensional histological images of the tissue samples, restricting the analysis to 2D. Existing approaches do not provide essential three-dimensional information such as cell volume, shape and …

CONTINUUM DISLOCATION DYNAMICS MODELING OF THE DEFORMATION OF FCC SINGLE CRYSTALS
… loading conditions. For monotonic loading, the cell structure is predicted and the wavelength is detected and shown to satisfy the empirical similitude law. The dislocation patterns are found to depend on the loading mode, monotonic versus cyclic, as well as the crystal orientation. For cyclic …

Investigations on Dry Beans (Phaseolus Vulgaris L.): Microstructure, Processing, and Antinutrients (Phytic Acid, Tanning, Enzyme Inhibitors)
The role of microstructure in processing and effects of several processing methods on antinutrients of dry beans were investigated. Proximate composition of whole beans showed minor differences among the ten varieties investigated. Most correlations between selected chemical constituents and …

Pathophysiology of Small Testes in Beef Bulls: Histopathological Features of Testes and Epididymides, Seminal Characteristics, and Endocrine Profiles (Testicular Hypoplasia, Degeneration, Breeding Soundness, Scrotal Circumference)
… suggested that the impairment in Leydig cell structure and function was caused by local factors, either the factors that caused the tubular damage or those consequent to the tubular damage. Hence, Leydig cell failure in these bulls may not be the primary cause of germinal epithelial loss …

Efforts Towards Micro Fuel Cells
… electrolytes are crucial components in fuel cells. However, the implementation of prevalent polymer electrolyte membranes leads to difficulties in manufacturing the fuel cell structure at the micron scale. Here we show that nanoporous silicon membranes with a thickness around 30∼50 …

Skeletal muscle fibre-type comparison of whole tissue and subcellular membrane phospholipids and fatty acids
Membranes are dynamic structures that affect cell structure and function. Compositional changes ofmembranes have been shown with the application of a perturbation; however these are limited to whole tissue analysis. The purpose of this thesis was to compare the phospholipid (PL) fatty acid (FA) …
