In this paper the expressions for stiffness and Damping derivatives are obtained in a closed form for perfect gas where the flow is quasi-steady and axi-axisymmetric, and the nose semi angle of the cone is such that the Mach number behind the shock . Results are presented for an oscillating cone for gas with , at different Mach numbers and semi con

Brain tumor account for a quarter of all childhood cancers, affecting about 1 in 2400 United Kingdom (UK) children under the age of 16 annually, while brain and other nervous system cancer incidence per 100,000 population in Peninsular Malaysia for age 0-19 years was 84/100000. Death occurs either as a result of catastrophic presentations with rais

Expression for Stiffness derivative for an Ogive is derived with the suppositions of the arc on the nose of the cone from the air is being considered as perfect gas and the viscosity being neglected, the motion is quasi-steady, and the nose deflection angle of the Ogive θ is in such a way that the M2 after the shock is > 2.5. It is seen that d

Sukuk are majorly used to raise funds in a large scale for the purpose of developments. With the increase of interest for responsible finance and investment, sukuk are used to meet such interests from the stakeholders. Instead of only looking for development purposes, Muslim scholars proposed that sukuk could be used for many other different purpos

In this research, lipase recovered from the skim latex of Hevea brasiliensis was immobilized via cross-linked enzyme aggregates (CLEA) technology, while supported by magnetic nanoparticles {MNPs), for properties enhancement. Hybrid immobilization may have affected the kinetic performances of the biocatalysts. The kinetic performance of both MNP sup

Different regulatory guidelines recommend establishing stability profile of pharmaceuticals at the time of drug development. The expiry date, retesting period and storage conditions of active drugs or products are established through stability analysis. Several regulatory guidelines exist for stability testing of pharmaceuticals. Mostly, ICH stabil

Natural antioxidants in spices and herbs have attracted considerable attention as potential inhibitors against the formation of mutagenic heterocyclic amines (HCAs) in heat-processed meat. In this study, the inhibitory activity of four spices/herbs and their mixtures on HCAs formation in grilled beef were examined. A simplex centroid mixture design

The huge amount of coffee pulp waste is an environmental problem. Anaerobic fermentation is one of the alternative solutions. However, availability of coffee pulp does not appear for year-round, whereas biogas needs continuous feedstocks for digester stability. This research uses coffee pulp from Arabica Coffee Factory at Mengani, Kintamani, Baliâ€

In Palembang in South Sumatra, Indonesia, Maulid celebrations are considered an important religious event in the lives of many Muslims. Over the past twenty years, there has been an expansion of activities, the driving force behind which has been a young generation of Alawiyin in Palembang. Maulid celebrations organized by the Alawiyin in Palembang

This study evaluated the efficacy of various organic solvents (80% acetone, 80% ethanol, 80% methanol) and distilled water for extracting antioxidant phenolic compounds from turmeric, curry leaf, torch ginger and lemon grass extracts. They were analyzed regarding the total phenol and flavonoid contents, antioxidant activity and concentration of som
