Solidification of Brass Casting in Green Sand Mould: A Numerical and Experimental Study
Abstract: Casting which is also known as founding, is one of the earliest metal shaping methods. It means the pouring of molten metal into the refractory mould then allowing it to solidify. After solidification removing of part from the mould either by breaking the mould or ejecting the mould part. Present study has been focused on solidification of brass in green sand mould formulation. Two-dimensional heat conduction equation in cartesian co-ordinate …

Effect of Magnetic Field on Casting Parameters
Abstract: AbstractThe casting process is one of the oldest manufacturing methods involving squeezing / jolting the green sand used as moulding material, and further was developed with use of binders such as clay/organic resins. The constants search for newer moulding material lead to the magnetic mould involving steel shots and application of magnetic field. The preliminary trials on one of the process parameters i. e. Magnetic field was carried out and …

ULTRAFAST LASERS AND ITS USE IN ELECTRONICS INDUSTRY
Abstract: The size of semiconductors and packaged devices continues to shrink enabling the devices to become more compact . This trend requires the deployment of sophisticated equipments with inbuilt lasers that have unique capability to process diverse materials with high precision , but without damaging the electronic components due to heat . There are diverse laser technologies utilising longer pulse width or ultrashort pulse (USP) width that are employed in electronic …

Gastroesophageal Reflux Disease and the Role of Prokinetics Along with PPIS
Abstract: Gastroesophageal reflux disease (GERD) is often confused with functional dyspepsia as dyspepsia symptom commonly coexist with heartburn and some patients with functional dyspepsia respond to proton pump inhibitor (PPI) therapy. Up to 25–50% of patients with functional dyspepsia defined according to Rome III criteria can have abnormal esophageal acid exposure. Functional dyspepsia presents of one or more of the following symptoms: Postprandial fullness, early satiation, epigastric pain or burning, and …

An Emerging Cause of Treatable Encephalitis: A Case of Anti-NMDA receptor (NMDAR) Encephalitis
Abstract: Anti-NMDA Receptor encephalitis is the most common type of autoimmune limbic encephalitis known. It is characterised by sub-acute onset of psychiatric symptoms along with refractory epilepsy, orofacial and limb dyskinesia and dysautonomia. High clinical suspicion and appropriate antibody testing in cerebrospinal fluid (CSF) and serum is required for early diagnosis and initiation of immunotherapy. Delay in treatment may lead to significant permanent neuro-deficits as well as mortality. Here, we present …

Synthesis and Characterization of TiO2 1% SiO2 of Crystal and its Bacterial Applications
Abstract: Three-dimensional (3D) TiO2 Anatase and Rutile structures have attracted much attention due to their optical properties. However, the large band gap of (3.2 eV) results in the fact that anatase TiO2 can act as photo catalyst and be excited by UV light, which only accounts for 3–5% of the solar energy. On considering that nobel metallatic nanomaterials can harvest visible light, in this paper, TiO2 and SiO2 nanocrystals with rod …
