The aim of this project has been to prepare nanocrystalline cellulose (CNC) from hydrochloric acid hydrolysis and optimise the process. CNC was also prepared from sulphuric acid hydrolysis to use as a reference. The starting material in both these processes was microcrystalline cellulose (MCC), therefore another cellulose source was used to try and prepare CNC from. The cellulose was extracted ...

New pulsation modes in two δ Scuti stars of Praesepe cluster, BQ and BW Cnc, have been detected during the STEPHI VI campaign in 1995. In particular, 3 frequencies for BQ Cnc and 9 frequencies for BW Cnc have been found above a 99% confidence level. The possibility of the presence of a g-mode present in BQ Cnc is discussed, considering its binarity. The effect of mutual interference between ver...

Due to its amazing physicochemical properties and high environmental compatibility, cellulose nano-crystals (CNC) hold great promise for serving as a strategic platform for sustainable development. Now, there has been growing interest in the development of processes using waste or residual biomass as CNC source for addressing economic and environmental concerns. In the present work, a combined ...

As a distributed computing system, a CNC system needs to be operated reliably, dependably, and safely. How to design reliable and dependable software and perform effective verification for CNC systems becomes an important research problem. In this paper, we propose a new modeling method called TTM/ATRTTL (timed transition models/all-time real-time temporal logics) for specifying CNC systems. TT...

We present an efficient approach to develop cellulose nanocrystal (CNC) hybrids with magnetically responsive Fe3O4 nanoparticles that were synthesized using the (Fe3+/Fe2+) coprecipitation. After 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-catalyzed oxidation of CNC, carbodiimide (EDC/NHS) was used for coupling amine-containing iron oxide nanoparticles that were achieved by dopamine li...

Optimizing the sequence of operations (SOS) is important factor in improving the productivity of machines and reducing the production cost. However, CNC programing packages are available and have been significantly improved program generation for CNC machines, but in most of these packages the SOS optimization is not considered. This paper, introduce an efficient solution to optimized SOS for m...

Reduction operations are a common and important feature in many parallel programming models. In this paper, we present a new reduction construct for Concurrent Collections (CnC). CnC is a deterministic, asynchronous parallel programming model in which data production and reduction can overlap. While reductions are most frequently incorporated in synchronous contexts where all data is available ...

During neural tube closure, Pax3 is required to inhibit p53-dependent apoptosis. Pax3 is also required for migration of cardiac neural crest (CNC) from the neural tube to the heart and septation of the primitive single cardiac outflow tract into the aorta and pulmonary arteries. Whether Pax3 is required for CNC migration and outflow tract septation by inhibiting p53-dependent apoptosis is not k...

The cardiac neural crest (cNC) lineage plays key roles in heart development by directly contributing to heart structures and regulating development of other heart lineages. The basic helix-loop-helix factor Hand2 regulates development of cardiovascular structures and NC-derived tissues including those that contribute to face and peripheral nervous system. Although Hand2 is expressed in cNC, its...

The type 1 alpha regulatory subunit (R1alpha) of cAMP-dependent protein kinase A (PKA) (PRKAR1A) is an important regulator of the serine-threonine kinase activity catalyzed by the PKA holoenzyme. Carney complex (CNC) describes the association 'of spotty skin pigmentation, myxomas, and endocrine overactivity'; CNC is in essence the latest form of multiple endocrine neoplasia to be described and ...
