The area is very hot and the high evaporation of water due to heat and less rain has caused salinity to the groundwater. Due to local climatic conditions, the decorative works of Rajasthan were executed on a shiny white plaster by a technique locally named Ala-Gila which is sometimes compared with the true fresco of Italy. The Persian colonial arts also flourished in this part and the color palette suddenly changed from vibrant to more shiny colors in the paintings. In this work, the microscopic observation of thin section was utilized to investigate geological and fine morphological features of the 16th century Amber fort lime plaster-a WHS site and a very popular tourist destination. The FTIR, XRD, and SEM photomicrographs of the plasters showed the stabilization of different crystalline phases of polymorphs of calcium carbonate. The chemical analysis and SEM-EDX data denote dolomitic limestone probably sourced for plaster works. The high amount of magnesium present in the raw material, the environmental conditions at the time of the application of the plaster, pH, etc. have stabilized calcite polymorphs in the plaster. The calcite meta-stable phases have undergone dissolution with time making the plaster weak. This has increased porosity, permeability, and resultant lowering of plaster's mechanical strength. The thermal analysis and cementation index of the plaster showed the use of non-hydraulic binder-rich air-lime for plaster works. The granulometric study showed the mixing of reddish-brown sand-size grains, and the aggregates were probably from the same location for major construction activity. The low proportion of aggregates led to reduced mechanical strength, and the is vulnerable to damage. It is to a major restoration of the ancient lime works with compatible materials as per analytical data","PeriodicalId":11194,"journal":{"name":"Current Science","volume":"57 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82303711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the highway sector, the highway projects are built by the con-cessioner, and in lieu of that, he generates revenue by collecting tolls from road users. The toll plazas built across the highways to collect tolls act as a bottleneck in highway facilities. Although the toll collection system has been improved worldwide, users are still expe-riencing an enormous delay at toll plazas due to congestion, especially in developing countries like India. This congestion is caused due to various factors such as long service time, an inadequate number of windows, traffic volume, categories of toll rates, etc., which lead to delay, degradation of capacity, and level of service. Different researchers in their countries have analysed all these factors. The present article gives a detailed literature review summarizing various studies on the different parameters related to toll plazas and proposes research gaps from the perspective of developing countries. The challenges and methodology for evaluating various parameters are also discussed, and a way for-ward for future research is suggested.","PeriodicalId":11194,"journal":{"name":"Current Science","volume":"28 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84134508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a large-scale multipurpose landscape consisting of a mosaic of crops, livestock and forest. The landscape also ensures almost all the ecosystem services that con-tribute to the well-being of more than 100 diverse ethnic groups (indigenous people) in the region. However, in recent years, rapid transition in the form of promotion and expansion of oil palm and rubber plantations as mooted and supported by the state has posed threats to the ecosystem and biodiversity especially the biocultural landscapes. Supported by empirical evidence (primary and secondary data), this study argues that as we increase the intensity of production or harvest of such crops, the environmental cost becomes unprecedented and immense to be offset by economic gain. The use of renewable biological resources as the foundation for a bioeconomy must be regulated in terms of environmental impact ra-ther than short-term financial dividends. Therefore, we need to develop optimization models for the biocultural landscape(s) that determine land use based on what is both economically and environmentally optimal.","PeriodicalId":11194,"journal":{"name":"Current Science","volume":"11 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85962983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
