The recent re-emergence of agrarian crises in Punjab has again drawn the attention of policymakers towards the viability of alternative crops. In this context, the study attempts production and marketing of one of the alternatives and viable crops (i.e., Olive) considered for the farmers in Punjab, Pakistan. The study was carried out in the Pothwar region of Punjab, and a total of 100 farmers were interviewed from four districts of Pothwar. The study results revealed that olive is a profitable crop since the benefit-cost ratio, net present value, and internal rate of return at a 10% rate of discount were 2.20, Rs. 263,338.00, and 31%, respectively. The findings also revealed that the channel with the least number of intermediaries was more efficient than the channels with more intermediaries. The study suggested that to take advantage of this new crop, controlled marketplaces with improved marketing facilities are needed to allow farmers to minimize their transport costs and achieve better prices for their products. Besides, linking fresh produce with agro-processing industries can go a long way in ensuring the returns from this crop.
Current and upcoming era is the era of Big Data, where it comes along with challenges between Big Data processing and security that raises problems. On one side, the large amount of trust related data have to be highly available, flexible and fast processing and on the other side, the trust and security of Big Data are the challenges. This paper highlights the problems of Big Data and it explores the study of Big Data processing and security with fast emerging technology of cloud computing that is its private cloud storage.
In recent work, deep eutectic solvents (DESs) as ionic liquid analogues have been abundantly used in catalysis. Herein, vanadium phosphorus oxide (VPO) catalysts were synthesized from mono-, bi-, and tri- metallic DES of Nb, Zr, and Mo metal dopants as structure-directing agents and electronic promoters for n-butane selective oxidation towards maleic anhydride. Higher MA selectivity and larger n-butane conversion was successfully obtained using the newly developed catalysts, while oxidation by-product COx (CO, CO2) was minimized. Characterization techniques including FTIR, DSC, XRD, TEM, SEM, EDS, Raman spectroscopy, TGA, XPS, and NH3-TPD were employed to fully characterize the DESs, precursors and catalysts. This work led to an increase of 7.8% in MA mass yield with 16% more n-butane conversion as compared to an unpromoted VPO catalyst. Moreover, the utilization of a low-carbon alkane brought in a green impact on the chemical plant as well as the environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
