Abstract: SCATSAT-1 carries a Ku-band scatterometer with a scanning pencil beam configuration. It deploys two beams, a vertically polarized outer beam and a horizontally polarized inner beam, to cover a swath of 1800 km. The mission mainly caters to oceanographic applications and weather forecasting, with the data being extensively used for forecasting, with the data being extensively used for cyclogenesis predictions across the globe and specifically, the tropical region. Since the launch of SCATSAT-1 in September 2016, the satellite and payload performances as well as mission and ground segment operations have been found to be nominal and satisfactory .This article highlights various levels of operational data products as well as algorithms used for deriving radar backscatter and retrieving windvector data from scatterometer measurements.

Abstract: Kesavan and Swaminathan have written three articles in 2018 dealing with the issues of food and nutritional security, sustainable agriculture and climate change, and provided in their own words a ‘proactive analysis’ of the available breeding technologies to meet these challenges. Almost every important issue related to agriculture has been touched upon. However, these reviews neither accurately state the history of plant breeding nor make any evidence-based analysis of the new developments in the area of genomics and genetic engineering to meet some of the critical challenges in crop breeding. The authors’ averments on genetically engineered (GE) crops completely align them with the position of overzealous environmentalists and ideologues, who have been campaigning against the use of GE technologies in crop breeding. The authors have distorted the history of plant breeding, rejected emerging consensus on the safety of GE crops, and suggested solutions that are grossly inadequate to meet the challenge of low-input, high-output agriculture. I analyse her most of the themes that the above mentioned two authors for a complete rejection of their analysis.

Abstract: Geology as a scientific enterprise emerged in the 18th century, both at intellectual and commercial levels, as a n explosive tool in the hands of imperial powers to locate and assess natural resources, and it eventually evolved into a post-modernistic manifestation of an all-embracing science of sustainability, called Earth-system science. Following the timeline of geology , which began as a classical scientific discipline , we see a prime example of socially embedded science that goes through various cycles of growth pangs and transitions during its evolution concomitant with epochal changes in social perspectives. This article explores how geology as a scientific discipline evolved to its present status.

Abstract: The average global climate is changing rapidly and increasing evidence indicates that global warming has consequences on numerous plant and animal species. Previous studies have shown significant fluctuations in the date advancement among wild species phenology in relation to warm springs. For instance, according to Szabo et al., four out of six investigated plant species in Hungry showed a significant advance in flowering dates by 1.9-4.4 days per decade, and the wood frog (Rana sylvatica) showed a trend toward earlier emergence by 19 days.

Abstract: Jamun, Syzgium cumini L. (Myrtaceae) is a common evergreen perennial fruit tree of tropical and subtropical regions. Being native to India and Mynmar, it is found throughout Southeast Asia and the Pacific regions. The tree bears annually, sweetish and sour, dark-purple berries that are much sought after for their anti-oxidant, anti-inflammatory, anti-microbial and free-radical scavenging properties. The existing literature provides an exhaustive list of various insect pests (~78 species) that could infest S.cumini in India. However, none of these reported seed borer, Anselmella kerrici (Narayanan et al., 1958) (Hymenoptera:Euliphidae) as an insect pest of jamun.The data base of insect pests hosted by the National Bureau of Agricultural Inset Resources (ICAR-NBAIR), Bengaluru, mentions the larval stages of A.kerrichi as phytophagous and feeding mainly on the seeds of jamun.

Abstract: India is a tropical country with a wide variety of habitat types that harbour a great diversity of fungi. These fungi include both beneficial forms like edible mushrooms, mould-producing industrial enzymes or other biotechnologically important products along with the ones like yeasts, indispensable for bread and wine industry and those that cause diseases in humans, animals and plants apart from a few that produce toxins. A large part of India’s fungal diversity is still unknown, as evidenced by regular reports of new genera or species being published .During a recent study of Maharashtra soils covering 31 districts, we have so far recovered 2 new genera and 9 new species of keratinophilic fungi. These findings suggest that even well-studied locations in India like Maharashtra harbour many novel taxa that might posses biotechnologically important properties. Therefore, there is need for a fresh, systematic survey of India’s soils (or other niches) to recover unknown fungi.

Abstract: The geographical location of Kolkata, where the city now exists with a metropolitan population of over 15 million, was once on the verge of the continental margin and was also neighbouring the proto –ocean of the Bay of Bengal (BoB).As aconsequence , most part of the present Bangladesh territory was under ocean water during the geological past. Detachment of micro-continents an excessive sediment deposition on continental marigns add more complexities to the ocean floor as well to continental regions, making it difficult to reconstruct precise plate tectonic history. These processes may lead to trapping of micro-continental pieces within the oceans and ocean territories beneath land masses. As a result, one can rely find old-aged, continental, silver-like Seychelles microcontinent in the northwestern Indian Ocean and Elan Bank in the southern Indian Ocean encircled by oceanic crustal rocks; it is even rarer to find the presence of oceanic rocks beneath land masses.

Abstract: Agriculture plays a vital role in India’s economy with over 58 % of the rural households dependent on it as their principal means of livelihood. The Indian agriculture sector, currently facing challenges of climate change, population growth and food security concerns, is progressively looking onwards means to leverage innovative technologies which can substantially enhance crop productivity. Artificial Intelligence (AI) is steadily emerging as a part of the technological evolution of this sector. Plantation crops are grown in India over an area of 3.7 million hectares and provide livelihood security to around 30 million people, besides contributing Rs 250 billion to the gross domestic product (GDP).To explore the gamut of application s of AI in agriculture, with special reference to plantation crops, a two-day workshop was held last year.

Subject: Fifty years of oral rehydration therapy: forgotten contributions from the Indian subscontnent
Keywords: oral rehydration therapy, Indian subcontinent
Abstract: Oral rehydration therapy (ORT) is a simple and powerful remedy that saves millions of children from diarrhoeal deaths every year. Improvising a simple oral remedy for diarrhoea was a Third World priority because the West, with good sanitation and ready access to intravenous (IV) fluids, rarely encountered diarrhoeal deaths. The scientific evidence in support of ORT began with researchers demonstrating the co transport phenomenon’, in which glucose was shown to enhance sodium absorption by specific transporter proteins. The ensuing clinical trials with ORT solutions of varying concentrations of sugar and salt, produced inconsistent and sometimes dangerous results. Early success came with the crucial 1968 Chittagong trials, when cholera patients in shock were treated intra-gastrically with ORT solutions. Subsequent field trials confirmed that ORT saves lives, even without IV fluids. Yet, translating ORT to the community remained problematic, until the Bangladesh liberation was (1971-72) when Dilip Mahalanabis (Infectious Diseases Hospital, Kolkata.) conducted the game-changing field trial in squalid refugee campus under extreme conditions. With neither doctors nor nursing support, family members administered ORT to dying patients. This pragmatic and frugal remedy went on to become the flagship public health programme under UNICEF and WHO. Though under-implemented to this day, ORT remains the greatest contributions from the Indian subcontinent towards achieving Sustainable Development Goals.ORT teaches many lesson: the delays in translating research to therapy , lure of gadgetry smothering frugal innovation, need for institutional endorsement from the West, in addition to the general indifference towards public health priorities.

Abstract: This communication presents experimental research findings on the application of the flower pollination algorithm (FPA) and the African buffalo optimization (ABO) to implement the complex and fairly popular benchmark Dejong 5 function. The study aims to unravel the untapped potential of FPA and the ABO in providing good solutions to optimization problems. In addition, it explores the Dejong 5 function with the hope of attracting the attention of the research community to evaluate the capacity of the two comparative algorithms as well as the Dejong 5 function. We conclude from this study that in implementing FPA and ABO for solving the benchmark Dejong 5 problem, a population of 10 search agents and using 1000 iterations can produce effective and efficient outcomes.

Keywords: 137Cs technology, soil erosion, soil erosion induced C-loss, soil conservation, slopping agricultural land.
Abstract: The use of Cesium -137 (137 Cs) as a potential environmental marker was examined for estimating soil erosion induced carbon losses on slopping agricultural land. Depth-wise incremental soil samples were taken from uneroded reference sites and four levels of cultivated slopping lands representing different erosion phase in Doon valley region of India. Comparing the 137Cs inventories for eroded sites with the reference inventory, the erosion rates were computed. The estimated erosion rates were then compared with the actual measured values of erosion at each erosion phase. Since soil erosion preferentially removes the finer soil particles, these results were used to assess erosion induced loss of OC. The result indicated that erosion in different phases relocate 137 kg Cha-1 in slightly eroded plots to 38 kg C ha-1 in severely eroded plots which in turn contributes to 27 to 77 kg C ha-1 the atmosphere as net source of C respectively.

Subject: Boron measurement in tourmaline from pegmatite veins
Keywords: Boron, electron probe micro analysis, pegmatite, tourmaline
Abstract: Tourmaline group of minerals, the primary source of boron, are cyclosilicates which are widespread in the earth’s crust. Earlier studies involving the nomenclature and classification of tourmaline were based on the measurement of its common elements (Al, Mn, Fe, Mg, etc.) In all such studies, boron was assumed to be fixed in the composition and restricted only to the triangular Structal site. However, recent discovery of the presence of boron in the tetrahedral structural site as well, necessitates the measurement of boron content. Much of the earlier attempts to measure boron were based on solution methods, and electron micro-probe analysis (EPMA) was the least used due to low levels of detection of its analytical crystals. In the present study, we quantify boron-particularly along with fluorine and other major elements-in tourmaline grains using high-sensitivity PC3 analytical crystal. We found that the measured boron content slightly exceeds that of the stoichiometrically calculated boron. Also, the studied tourmalines come under the alkali group in general and belong to the schorldravite solid solution series in particular.

Abstract: The use of biosurfactants has been limited because of their low yield and high production cost. A central composite design was used to study the interactive effect of sucrose, yeast extract and sodium chloride which were the most influencing variables. Response surface analysis showed that the quadratic model with R2 value of 0.9983 was fit for biosurfactant production. When genetic algorithm was used for maximization, the optimal activity (oil displacement zone) was found close to that obtained by response surface methodology, both of which were close to the predicted value. Bio surfactant production was enhanced by 1.2-fold using these approaches.

Subject: Xuefeng Cordyceps: insights into species diversity, life cycle and host association
Keywords: Clerodendrum crytophyllum, cordyceps, Endoclita davidi, traditional Chinese medicine
Abstract: Cordyceps) =Cordyceps sensu lato) fungi are rather well known as entomopathogens and also for their medicinal importance in curing many diseases. Many cordyceps species with widespread distribution throughout China have been recorded earlier. However, their taxonomy, hosts, lie cycles and the plants on which the host insects reside in are poorly understood, and have sometimes led to confusion in the proper identification of the species. In this study, Xuefeng Cordyceps collected from Xuefeng Mountain, Hunan hina are identified and an assessment of their life cycles, proper hosts and plants they are associated with is made through morphological and DNA sequence-based analyses. Morphological characterization reveals that Ophiocaordyceps axuefengensis from this region as commonly accepted by mycologists and local people. Species collected also include Beauveria bassiana (sequal and asexual),Metacordyceps macro acicularis and Ophiocordyceps ramosissimum. Our result challenges previous taxonomic arrangement with regard to host identity. The hosts, previously mistaken for larvae of Endoclita nodus, are corrected herein as larvae of Endoclita davidi (Lepidoptera: Hepialidae). Ribosomal DNA sequence analyses based on the ITS regions also confirm that Clerodendrum crytophyllum Lamiaceae) is the plant on which the host insects reside. Morphological illustrations, where approapriate, are given for the cordyceps species, hosts and plants. The infection mechanism and, life cycle of the cordyceps are also outlined.

Abstract: Recent exploration efforts in Kudada-Turamdih area has brought to light, for the first time, serpeninized peridotite-hosted uranium mineralization (up to 0.188 % U308) of polymetallic nature (U-Cr-Ni-Mo-REE-Fe-Mg) in the domain of Singhbhum Shear ZAone (SZ) .The peridodite has been emplaced into the Iron Ore Group (IOG) and represents late phase activity in the IOG. And represents late phase activity in the IOG.Explaratory and represents drilling has established substantial lateral (600 m) and downdip (1000 m) continuity of the mineralization. Subhedral to an hedral disseminated uraninite grains (10-600 µm) with cell dimensions of 5.4498 to 5.4650 Ǻ suggest crystallization in meso to hypo-thermal range ( 300-500 ̊C) .Magnetite, chromite, molybdenite, cobaltite, nickeline, vaesite,cerussite, pyrite and chalcopyrite have also been identified in the REE enriched (Av. 157 ppm) uraniferous peridotite. Presence of MgO (18-28 %), Cr (295-3165 ppm), Ni (222-9530 ppm), Au (11-30 ppb), Pt (47-95 ppb) and As (15-755 ppm) suggests komatiitic parentage of host rock. Discovery of polymetallic mineralization in serpentinized periodotite, a hitherto unknown geological environment, opens up scope for further research and enhancement of uranium resources in the SSZ.
