Sāncipāt was a popular manuscript writing base of early and medieval Assam, North East India. Tens of thousands of Sāncipāt manuscripts still exist in the state, some of them centuries old, without fading ink and min-iature painting despite its harsh hot and humid climate. Traditionally, Sāncipāt was made from the bark of the Sānci tree using an arduous procedure. In this study, we analysed the physico-chemical proper ties of the traditionally prepared model and old Sāncipāt folios at different stages of preparation using FT-IR, XRD and SEM-EDX spectra, weight loss during degumming, tensile strength, gloss index and antifungal properties. A comparison of data with freshly prepared Sāncipāt folios showed intact internal structure and str ength in the old ones. The antifungal property obser ved in Sāncipāt is attributed to Tutia used during degumming of the bark, and two pigments, viz., Hengul and Hāitāl applied as thin coating and border respectively. Partial degumming, coating with fatty pulse, application of Hāitāl and Hengul, and repeated pressing, smoothening and drying together impart strength and glossiness to Sāncipāt manuscripts.

Dholavira was one among the five largest settlements (probably six) of the Harappan civilization during the third millennium BCE . The location of this site in a desolate corner of Khadir Island in Kachchh, Gujarat, India, speaks well of the planning and ingenuity showed by the Harappans for making it an urban and adminis-trative centre. Excavations at this site between 1989 and 2005 brought to light a long and continuous occupation of nearly 1500 years ( c . 3000–1500 BCE ), which records the rise, culmination and fall of the Harappan Civilization. Evidences for various craft activities are found from the earliest levels onwards and the Harappans exploited various lithic raw materials for both utilitarian purposes and making ornaments. Kachhch and the Gujarat mainland are rich in raw material resources in general and agate–carnelian, limestone, various types of clay, copper–lead–silver and steatite, in particular. Dholavira contains both raw materials and finished artefacts, thus presents an ideal scenario to study. In the present study, we interpret the mineralogical characterization and probable provenance of the raw materials from different spatio-temporal contexts at the Dholavira site using techniques like XRD and SEM-EDS analysis. Samples of clay, stone raw materials and a few artefacts were selected from among the innumerable resources available at the site.

In holometabolous insects, adult develops through larval and pupal stages. Limb regeneration has an impact on different life traits of organisms. In the present study, we found that limb regeneration of two ladybird species of different body size affected their life attributes. The fourth instar of Propylea dissecta and ladybird Coccinella septempunctata were taken from laboratory stock and ablated. Larvae were observed until adult emergence. Emerged adults were kept in different mating treatments. Unregenerated adults of ladybirds took more time to commence mating with shorter copulation and reduced fecundity and per cent viability. Thus, it can be concluded that regeneration ability modulates life attributes of ladybirds, irrespective of body size.

Globally, trawl is the major fishing gear used in marine fisheries and in India, it contributes to more than one-third of the marine fish production. Trawl fishing has been critically evaluated from a sustainability perspective, especially analysing its bycatch composition. Most of the bycatch from trawlers contains valuable edible species with high market demand. However, a portion of the bycatch which does not have such demand in the edible fish market, known as low-value bycatch (LVB), continues to be a matter of concern from an ecological and economic perspective. During 2017–19, 30–60% of trawl landing in India was constituted by LVB

The under representation of women in Science, Technology, Engineering and Mathematics (STEM) is always a matter of concern worldwide. The sustainability of women scientists in STEM and further getting recognition, awards, rewards and leadership position has been a challenge. However, some of the women scientists have received fellowships like J.C. Bose Fellowship and secured leadership positions. This article analyses discipline-wise and institute-wise distributions of J.C. Bose women Fellows. Further, it describes notable achievements of some of the women J.C.

Biological phenomena often emerge based on the interaction between pathways, cells and tissues, rather than a single set of genes or proteins. This has led to the emer-gence of systems medicine. Predictive medicine is another emerging field that aims to predict the disease onset, progression, deterioration, risk and treatment strategies. In this article, we review how systems and computational tools are being used globally in the drug discovery pipeline. With increase in the amount of biological data being generated, data integration is also a critical aspect in systems biology. Towards this, we describe the use of various data integration frameworks. We also analyse the global and local funding patterns, regulations and challenges and propose recommendations to enable India as a key player in this area

A large portion of unused crop residues is burnt in the fields primarily to clear the left-over straw and stubbles after the combine harvest. Studies have reported several ill effects of crop-residue burning on soil organic carbon and fertility, including reduction in productivity in the long term, environmental pollution and human health. It also produces greenhouse gases causing global warming. Rice and wheat produce large amounts of residue in India. Non-availability of labour, the high cost of residue removal from the field and the increasing use of combines in harvesting the crops are the main reasons for burning crop residues in the fields. Rice straw is unsuitable animal feed due to its high silica content and wheat straw for due to its hard stem and diffi-culty chewing in unchopped form. Using supplements like urea and is feeding straw sprayed with urea improves its nutritive value and intake. We have developed a mechanized baler equipped with a urea spraying system for spraying urea during baling operations on crop residues (paddy or wheat straw) to enhance their nutritional value. The developed system was evaluated in combine a harvested wheat residue field and nutritional analysis was performed. The crude protein in untreated wheat straw increased from 3.68% to 10.10% after urea treatment. The metabolizable energy was also found to improve by 3% compared to untreated straw. Thus, urea-treated bales have potential use in dairy farming.

The mafic granulite rocks f rom the Makrohar Granulite Belt of the Chotanagpur Granite Gneissic complex (CGGC) have been studied with reference to their petrography, mineral chemistry and pressure–temperature ( P–T ) conditions of metamorphism. The common mineral assemblage observed within different thin sections is orthopyroxene–clinopyroxene–hornblende–plagioclase– biotite–quartz. The average P–T condition of the mafic granulites in the study area suggests a peak of metamorphism at 799 ° ± 40 ° C/6.3 ± 0.9 kbar. However, the peak P–T estimate obtained from the conventional two-pyroxene thermobarometer is 5.83–6.47 kbar and 887 ° ± 62 ° C at a fixed pressure of 6 kbar, followed by post-peak P–T conditions of metamorphism at 590 ° –693 ° C/ 2.1–2.4 kbar.

The influence of various parameters on corrosion rate in reinforced concrete was examined using analysis of variance for crack initiation and crack propagation phases. Water–cement (w/c) ratio was found to be the most significant factor before the onset of concrete surface crack, followed by the time of wetting. In the crack propagation phase, contribution of w/c ratio reduced while time of wetting and external chloride concentration became prominent. The concrete cover values of 30 mm and 60 mm affected the corrosion rate marginally. The diameter of reinforcing steel and spacing between bars were the least contributing factors to the corrosion rate under both phases.
