    Opis:
    A new health threat in the form of a new variant of Covid-19 called Omicron has emerged globally in this holiday season. This new variant has been declared a variant of concern (VOC) by the World Health Organization and experts are expecting another wave of the pandemic. A lot still unknown about this variant and researchers worldwide are conducting studies to find the nature and characteristics of this mutated strain. Cases have begun to rise dramatically around the world and many countries have already imposed travel restrictions again to prevent disease transmission. It is being speculated that this particular variant has got tendency of immune escape and therefore can even infect fully vaccinated individuals. Vaccination and adhering to Covid-19 guidelines and protocols can curtail the spread of the virus. The present paper focuses on what is currently known about this variant, antigen diagnostic tests, importance of getting fully vaccinated and having booster dose etc. If we want to emerge from this pandemic, countries should practice vaccine equality and solidarity for the good of mankind.

    Opis:
    The second wave of the COVID-19 pandemic has affected India significantly with country reporting more than 400,000 cases in the month of May 2021 and health system almost collapsing. This was attributed to the new mutant strain also called as the ‘Delta Strain’ which led to high surge of cases across the country. As the country was stabilising over this situation, another imminent threat in the form of Covid Associated Mucormycosis (CAM) challenged the already burdened health system of India. Also called as ‘Black Fungus,’ cases of CAM began to rise rapidly in the last week of May 2021 with multiple states reporting steady rise in the number of cases. Based on the published literature, India contributed to approximately 71% of global cases of CAM from December 2019 to start of April 2021, with majority of the cases occurring during the second wave. The present paper focuses on the epidemic of CAM during the second wave in India highlighting the causes, symptoms and various treatment modalities that have been adopted to cure the disease. Also, spotlight has also been thrown on some other nations where cases of CAM have begun to emerge. Some key recommendations are also mentioned which can prove vital towards disease prevention.

    Fluorescence spectra of strontium sulphide phosphors activated by three activators viz. Mn, Cu, and Gd individually and in different combinations have been discussed at length. X-ray is used as excitation source. Probable inferences are drawn regarding energy transfer phenomenon. The two channels for transfer of energy are concluded in present phosphor series. A model is also proposed.

    Opis:
    An investigation is made on the effect of Hall currents on thermal instability of a compressible couple-stress fluid in the presence of a horizontal magnetic field saturated in a porous medium. The analysis is carried out within the framework of the linear stability theory and normal mode technique. A dispersion relation governing the effects of viscoelasticity, Hall currents, compressibility, magnetic field and porous medium is derived. For the stationary convection a couple-stress fluid behaves like an ordinary Newtonian fluid due to the vanishing of the viscoelastic parameter. Compressibility, the magnetic filed and couple-stress parameter have stabilizing effects on the system whereas Hall currents and medium permeability have a destabilizing effect on the system, but in the absence of Hall current couple-stress has a destabilizing effect on the system. It has been observed that oscillatory modes are introduced due to the presence of viscoelasticity, magnetic field porous medium and Hall currents which were non-existent in their absence.

    Opis:
    Casting process takes a major percentage of manufacturing products into consideration. No-bake casting is swiftly developing technology for foundry industries. In the no-bake family, furan no-bake casting process employs resins and acid catalyst to form a furan binder system. However, this process configures castings with augmented strength and quality surface finish. Compressive strength, transverse strength and tensile strength of moulds are also high in this furan binder system. Hence this method is apt for producing accurately dimensioned castings. Our well thought-out deliberations in the subsequent write up entail the numerous effects of variation of resin and acid catalyst on the surface defect i.e. sulfur diffusion on the surface of FNB casting. Furan resin; used in the production of casting is furfuryl alcohol and acid catalyst is sulphonic acid. Sulfur diffusion is tested by Energy-dispersive X-ray spectroscopy (EDX) analysis and also by the spectrometer with jet stream technology. This paper also comprises economic advantages of optimizing resin because furan resin is expensive and catalyst with reduction of sulfur diffusion defect as it saves machining, labor cost, and energy.
