The goal of the ALPHA collaboration at CERN is to test CPT conservation by comparing the 1S–2S transitions of hydrogen and antihydrogen. To reach the ultimate accuracy of 1 part in 10 18 , the (anti)atoms must be trapped. Using current technology, only magnetic minimum traps can confine (anti)hydrogen. In this paper, the design of the ALPHA antihydrogen(More)
We investigated DNA methylation and polymorphism in the methylated DNA using AFLP based methylation-sensitive amplification polymorphism (MS-AFLP) markers in ecotypes of Jatropha curcas L. growing in similar and different geo-ecological conditions. Three ecotypes growing in different geo-ecological conditions with environmental heterogeneity (Group-1) and(More)
Jatropha curcas L. (Euphorbiaceae) has acquired a great importance as a renewable source of energy with a number of environmental benefits. Very few attempts were made to understand the extent of genetic diversity of J. curcas germplasm. In the present study, efforts were made to analyze the genetic diversity among the elite germplasms of J. curcas,(More)
The present study aimed to assess not only the efficacy of sap from two seaweeds Kappaphycus alvarezii (K-sap) and Gracilaria edulis (G-sap) on productivity and quality of Zea mays under rain-fed condition, but also to quantify whether sap application is beneficial in terms of lowering the carbon and phosphate footprint of mineral fertilizers per unit of(More)
Seaweeds, an integral part of marine coastal environment, are an important food, industrial raw materials and biostimulants for crop growth due to the presence of a number of plant growth stimulants. The sap of an economically important seaweed Kappaphycus alvarezii (K-sap) is gaining momentum for sustainable intensification of agricultural productivity. In(More)
Sustainable intensification of agricultural productivity is a global challenge. The sap of the commercially important red seaweed, Kappaphycus alvarezii, has been of interest in this regard, and its application as foliar spray has had a profound impact on the yields of many crops. It has been shown to contain indole acetic acid, kinetin, zeatin and(More)
The main objective of the present study is to effectively utilize the de-oiled algal biomass (DAB) to minimize the waste streams from algal biofuel by using it as an adsorbent. Methylene blue (MB) was used as a sorbate for evaluating the potential of DAB as a biosorbent. The DAB was characterized by SEM, FTIR, pHPZC, particle size, pore volume and pore(More)
A summary is presented of preliminary studies of three 100 TeV center-of-mass hadron colliders made with magnets of different field strengths, 1.8T, 9.5T and 12.6T. Descriptions of the machines, and some of the major and most challenging subsystems, are presented, along with parameter lists and the major issues for future study.
Variability in traits of 15, diverse 6-year-old candidate plus trees of Jatropha curcas was determined to identify the best gain heritable traits correlating with oil yield for Jatropha improvement. Study was carried out on 15 6-year-old candidate plus trees of Jatropha curcas adapted on semi-arid wasteland with an objective to assess variation in(More)
