Introduction: Laboratory measurements of meteorite reflectance spectra rarely match telescopic observations of asteroid reflectance spectra due to the process (es) of space weathering, which rapidly darken and redden asteroid surface on million-year timescales [e.g. 1-2]. While most main belt asteroids appear weathered, a fraction of near-Earth asteroids (the Q-types) appear unweathered – possi...

Bay leaf (Syzygium polyanthum (Wight.) contains polyphenolic compounds that are beneficial in the treatment of hypercholesterolemia by reducing Low Density Lipoprotein (LDL) levels. The dosage form mucoadhesive microgranules is able to prolong active substance contact time with mucosa give better therapeutic effect. This study aims make bay extract different polymers Hydroxy Propyl Methyl Cellu...

To ensure safety when transporting dangerous goods, it is important to specify the flow properties of respective solid filling substance packagings. For this purpose, angle repose currently used for UN approvals in Germany. Measurements were carried out on 12 powdery or granular substances applying measuring methods customary test centres. The results differ significantly from each other. In ad...

Since orally disintegrating tablets (ODTs) of tramadol hydrochloride are not available in the market, so an attempt has been taken to formulate and evaluate ODT preparation hydrochloride. In this present work, direct compression was technique used for preparing using superdisintegrants like croscarmellose sodium, sodium starch glycolate crospovidone at different concentrations. Prepared formula...

The combination of citric acid-tartaric acid and sodium bicarbonate in effervescent granules has an important role providing effect. Citric tartaric are organic acids that can react with when they come contact water. This reaction results the release carbon dioxide gas, which a splitting effect makes dissolve rapidly Research on formulation evaluation andaliman fruit ethanol extract aims to opt...

Objective: The objective of the study was to prepare and evaluate formulation granules effervescent from kirinyuh mareme leaves as an antioxidant.
 Methods: method making with wet granulation method. used for granules, meanwhile, evaluations included organoleptic tests, water content, solubility time, pH preparation, compressibility, flow time angle repose antioxidant activity.
 Resul...

A set of suitable parameter values is crucial in discrete element method (DEM) simulations. As a non-spherical particle, the coefficients rolling friction between maize seed particles and boundary are hard to measure directly must be obtained by calibration. In this paper, taking three representative varieties as research objects, necessity for accurate calibration boundaries investigated. Subs...

The powder spreading is a vital step of powder-based additive manufacturing (AM) processes. quality spread can considerably influence the properties fabricated parts. Poorly packed beds with high surface roughness result in printed part layers large porosity and low dimensional accuracy, leading to poor mechanical properties. Therefore, spreadability its dependence on process parameters charact...
