Dijet production in generic contact interaction at linear colliders

We consider dijet production at a e+e− collider in a class of effective theories with the relevant operators being four-fermion contact interaction. Despite the nonrenormalizable nature of the interaction, we explicitly demonstrate that calculating QCD corrections is both possible and meaningful. Calculating the corrections for various differential distributions, we show that these can be substantial and significantly different from those within the SM. Furthermore, the corrections have a very distinctive flavor dependence.

Effect of loading rate on crystallization of metallic glass supercooled liquids

Metallic glasses exhibit unique thermoplastic processing capability, which is enabled by their metastable supercooled liquid state below the crystallization temperature. The thermoplastic processing critically depends on the crystallization time (processing time window), temperature (viscosity), applied load, and strain-rate. Among these parameters, the effects of crystallization time and processing temperature have been extensively studied. However, the effects of load and loading rate have not been thoroughly investigated. In this work, we performed a systematic study of load on the supercooled liquid state of three metallic glass formers: Pt-based, Zr-based, and Pd-based. The results show that the load-response of a metallic glass supercooled liquids is strongly composition dependent. The onset temperature of crystallization decreases with increasing load in Pt-based metallic glass whereas for Zr-based and Pd-based metallic glasses the onset temperature remains unchanged. The crystallization peak time is reduced for all three metallic glasses after thermoplastic forming. The results are discussed in terms of nucleation and growth of crystallites in metallic glasses.

Detection of different adulteration from milk with non-destructive approach (Near infrared spectroscopy): A short review

The present article is a review work about the role of near infrared spectroscopy to detect different adulterantsin the milk. Milk is a nutritive food and very useful and healthy drink for the child and senior citizens. It has various nutrition parameters. But, to increase the profit many adulterantsare added in the milk which are very harmful for human body. The adulterants can be detected using various chemical methods which are time consuming, hazardous and destructive in nature.Thus there is need of a nondestructive, green and rapid method to detect the adulteration. Near Infrared spectroscopy (NIRS) is one of the most useful and robust technique which needs no minimal sample preparation and is rapid, green, and non destructive in nature. The review covers the various nondestructive methods to detect various adulterants.

Positive Impact of COVID19 on Indian Ecosystem: A Brief Review

In the present days, COVID-19 (SARS-Cov-2) has a serious issue and has created many challenges not only in the medical research but also in human life style. This virus has spread out within India also after originated from China and the rate of transmission inrease day by day. India has seen over 8 lakh cases of infections and over 20,000 cases of death till first week of July, 2020. Government of India has announced absolute lockdown to reduce the transmission rate. The present review study indicates a comparative study on the natural activity regarding the air and the water pollution before and after this lockdown. The study has presented the literature about the variation of concentration of pollutant in the air and water. The studies have been conducted and explained the scenario of the Indian ecology.
