Optimization of granule size and tablet properties in a twin screw granulator: the influence of process and formulation parameters
… granulator. Product characteristics (e.g., granule yield and strength, tablet crushing force, friability, and dissolution) are determined as being both formulation and process dependent. Screw speed, number and type of mixing elements, temperature, and binder content are investigated via …

Regime map development for co-rotating twin screw granulation
… between operating conditions and the granules. This thesis focused on one of the main equipments – twin screw extruder and attempted to develop the regime maps and the granulation hypothesis for twin screw granulation. In order to compare the mechanism with high-shear granulation that …

Factors affecting drug distribution in granules.
… affecting the distribution of a low dose drug in granules prepared by the massing and screening method have been investigated. Five granule formulations were used to elucidate the effect of the "relative solubilities" on the drug distribution in granules. These were borax/lactose, sodium …

Optimisation of granola breakfast cereal manufacturing process by wet granulation and pneumatic conveying
… the influence of process parameters on key granule aggregate quality attributes such as granule size distribution and textural properties of granola were investigated. The experimental results show that the impeller rotational speed is the single most important process parameter which …

Mechanistic Understanding of the NOB Suppression by Free Ammonia Inhibition in Continuous Flow Aerobic Granulation Bioreactors
… a mixture of large anammox-supported aerobic granules (ASAGs) and small conventional aerobic granules (CAGs) can be maintained stably for extended periods of time. The influent NH4+ was kept at 50 - 60 mg N L-1 to verify that the upper range of total ammonia nitrogen (TAN) for domestic …

TDP-43 Is Directed to Stress Granules by Sorbitol, a Novel Physiological Osmotic and Oxidative Stressor
… that TDP-43 associates with cytoplasmic stress granules, which are transient structures that form in response to stress. In this study, we establish sorbitol as a novel stressor that directs TDP-43 to stress granules in Hek293T cells and primary cultured glia. We quantify TDP-43 association with …

Multi-color visualization and quantification of single RNA translation and HIV-1 programmed ribosomal frameshifting in living cells
… RNAs interactions with ribonucleoprotein (RNP) granules during cellular stress. NCT was used to image real-time single RNAs, their translational output, and RNA-granule interactions during stress. Although translating mRNAs only interact with RNP granules dynamically, non-translating mRNAs can …

The impact of stress history of deformable dry granules on the mechanical properties of tablets
… understanding of the relationship among the granule composition, individual granule property, downstream robust processing, and the final tablet attributes is critical for rational development of a quality tablet. However, in the dry granulation literature, milled granules that are …

Crystallization of Synthetic Blast Furnace Slags Pertaining to Heat Recovery
… of parameters such as the slag/air ratio and granule size on the heat recovery and glass content of slag.

Modeling and Control of Batch Pulsed Top-spray Fluidized bed Granulation
… models were developed to predict the mean size of granules, yield, relative width of granule distribution, Hausner ratio and final granule moisture content. Validation experiments have shown the reliability and effectiveness of using the Box-Behnken experimental design method to study a …

Morphological granulometry for texture analysis
… was also applied to images of Indian black tea granules, which are ordered according to granule size. Better classification was achieved for both sets of images compared to previously published results for these images. The performance of grey level co-occurrence matrix (GLCM) features from the …

Studies on the fluidised bed granulation process.
… the objectives of elucidating the mechanism of granule formation and identifying the fundamental parameters affecting granule quality thereby enabling the true benefits of the process to be realised. Initially the effect of seven process variables upon granule quality was quantified using a …

Microfluidic assembly and packing dynamics of colloidal granules
… requires the ability to precisely control the granule size, size distribution, shape, and composition. Many methods exist for producing colloidal granules, including fluidized granulation, high shear mixer granulation, and spray drying. However, none of these methods provide adequate control …

Ruolo della TDP-43 nella formazione dei granuli da stress nella Sclerosi Laterale Amiotrofica
… studies suggest that TDP-43 may regulates stress granules dynamics that are cytoplasmic structures composed of non-translating messenger ribonucleoproteins (mRNPs) that rapidly aggregate in cells exposed to adverse environmental conditions. Stress granules function in part to triage RNA and …

Fundamental studies of sourdoughs fermented with Weissella cibaria and Lactobacillus plantarum: influence on baking characteristics, sensory profiles and in vitro starch digestibility of gluten-free breads
… from sucrose in situ with a molecular size of 106 to 107 kDa. EPS formation in all breads was analysed using size exclusion chromatography and highest amounts were formed in buckwheat (4 g/ kg) and quinoa sourdough (3 g/ kg). The facultative heterofermentative Lactobacillus plantarum …

Influence of head-moisture treatment on functional, colour and thermal properties of bambara ground-nut starch
… oval and round shape for bambara starch granules, with varying sizes. The range of the granule size width was 4.2 – 4.7 mm and 10 μm for length. The modified starches showed some changes in granule morphology as they seem to disintegrate with application of HMT. Unmodified and HMT - BG …
