  • Kutch Basin Forms the North-Western Part of the Western Continental
    Basin Introduction :. Kutch basin forms the north-western part of the western continental margin of India and is situated at the southern edge of the Indus shelf at right angles to the southern Indus fossil rift (Zaigham and Mallick, 2000). It is bounded by the Nagar- Parkar fault in the North, Radhanpur-Barmer arch in the east and North Kathiawar fault towards the south. The basin extents between Latitude 22° 30' and 24° 30' N and Longitudes 68° and 72° E covering entire Kutch district and western part of Banaskantha (Santalpur Taluka) districts of Gujarat state. It is an east-west oriented pericratonic embayment opening and deepening towards the sea in the west towards the Arabian Sea. The total area of the basin is about 71,000 sq. km of which onland area is 43,000 sq.km and offshore area is 28,000 sq.km. upto 200 bathymetry. The basin is filled up with 1550 to 2500m of Mesozoic sediments and 550m of Tertiary sediments in onland region and upto 4500m of Tertiary sediments in offshore region (Well GKH-1). The sediment fill thickens from less than 500m in the north to over 4500m in the south and from 200m in the east to over 14,000m in the deep sea region towards western part of the basin indicating a palaeo-slope in the south-west. The western continental shelf of India, with average shelf break at about 200 m depth, is about 300 km wide off Mumbai coast and gradually narrows down to 160 km off Kutch in the north.

  • Herein After Termed As Gulf) Occupying an Area of 7300 Km2 Is Biologically One of the Most Productive and Diversified Habitats Along the West Coast of India
    6. SUMMARY Gulf of Katchchh (herein after termed as Gulf) occupying an area of 7300 Km2 is biologically one of the most productive and diversified habitats along the west coast of India. The southern shore has numerous Islands and inlets which harbour vast areas of mangroves and coral reefs with living corals. The northern shore with numerous shoals and creeks also sustains large stretches of mangroves. A variety of marine wealth existing in the Gulf includes algae, mangroves, corals, sponges, molluscs, prawns, fishes, reptiles, birds and mammals. Industrial and other developments along the Gulf have accelerated in recent years and many industries make use of the Gulf either directly or indirectly. Hence, it is necessary that the existing and proposed developments are planned in an ecofriendly manner to maintain the high productivity and biodiversity of the Gulf region. In this context, Department of Ocean Development, Government of India is planning a strategy for management of the Gulf adopting the framework of Integrated Coastal and Marine Area Management (ICMAM) which is the most appropriate way to achieve the balance between the environment and development. The work has been awarded to National Institute of Oceanography (NIO), Goa. NIO engaged Vijayalakshmi R. Nair as a Consultant to compile and submit a report on the status of flora and fauna of the Gulf based on secondary data. The objective of this compilation is to (a) evolve baseline for marine flora and fauna of the Gulf based on secondary data (b) establish the prevailing biological characteristics for different segments of the Gulf at macrolevel and (c) assess the present biotic status of the Gulf.

  • Smart Border Management: Indian Coastal and Maritime Security
    Contents Foreword p2/ Preface p3/ Overview p4/ Current initiatives p12/ Challenges and way forward p25/ International examples p28/Sources p32/ Glossary p36/ FICCI Security Department p38 Smart border management: Indian coastal and maritime security September 2017 www.pwc.in Dr Sanjaya Baru Secretary General Foreword 1 FICCI India’s long coastline presents a variety of security challenges including illegal landing of arms and explosives at isolated spots on the coast, infiltration/ex-filtration of anti-national elements, use of the sea and off shore islands for criminal activities, and smuggling of consumer and intermediate goods through sea routes. Absence of physical barriers on the coast and presence of vital industrial and defence installations near the coast also enhance the vulnerability of the coasts to illegal cross-border activities. In addition, the Indian Ocean Region is of strategic importance to India’s security. A substantial part of India’s external trade and energy supplies pass through this region. The security of India’s island territories, in particular, the Andaman and Nicobar Islands, remains an important priority. Drug trafficking, sea-piracy and other clandestine activities such as gun running are emerging as new challenges to security management in the Indian Ocean region. FICCI believes that industry has the technological capability to implement border management solutions. The government could consider exploring integrated solutions provided by industry for strengthening coastal security of the country. The FICCI-PwC report on ‘Smart border management: Indian coastal and maritime security’ highlights the initiatives being taken by the Central and state governments to strengthen coastal security measures in the country.

Vadivel Department of History , Presidency College , Chennai , Tamil Nadu. ABSTRACT The present paper is an attempt to focus the physical features, present position and past history of the Ramnad District which was formed in the tail end of the Eighteenth Century. No doubt, the Ramnad District is the oldest district among the districts of the erstwhile Madras Presidency and the present Tamil Nadu. The District was formed by the British with the aim to suppress the southern poligars of the Tamil Country . For a while the southern poligars were rebellious against the expansion of the British hegemony in the south Tamil Country. After the formation of the Madras Presidency , this district became one of its districts. For sometimes it was merged with Madurai District and again its collectorate was formed in 1910. In the independent Tamil Nadu, it was trifurcated into Ramnad, Sivagangai and Viudhunagar districts. The district is, historically, a unique in many ways in the past and present. It was a war-torn region in the Eighteenth Century and famine affected region in the Nineteenth Century, and a region known for the rule of Setupathis. Many freedom fighters emerged in this district and contributed much for the growth of the spirit of nationalism. KEY WORDS : Ramanathapuram, Ramnad, District, Maravas, Setupathi, British Subsidiary System, Doctrine of Lapse ,Dalhousie, Poligars.

  • Bacillus Cavernae Sp. Nov. Isolated from Cave Soil Liling Feng, Dongmei Liu, Xuelian Sun, Gejiao Wang3 and Mingshun Li3
    International Journal of Systematic and Evolutionary Microbiology (2015), 00, 1–7 DOI 10.1099/ijsem.0.000794 Bacillus cavernae sp. nov. isolated from cave soil Liling Feng, Dongmei Liu, Xuelian Sun, Gejiao Wang3 and Mingshun Li3 Correspondence National Key Laboratory of Agricultural Microbiology, College of Life Science and Technology, Gejiao Wang Huazhong Agricultural University, Wuhan, 430070, PR China [email protected] A Gram-stain-positive, spore-forming, motile, strictly aerobic, rod-shaped bacterium, designated strain L5T, was isolated from soil of Tenglong cave, China. 16S rRNA gene sequence analysis showed that strain L5T was related most closely to Bacillus asahii MA001T (96.5 %) (the highest 16S rRNA gene sequence similarity), Bacillus kribbensis BT080T (96.4 %) and Bacillus deserti ZLD-8T (96.2 %). The DNA G+C content of strain L5T was 45.6 mol%. The major menaquinone was MK-7. The major fatty acids were iso-C14 : 0, anteiso-C15 : 0 and iso-C16 : 0, and the major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. In addition, strain L5T had different characteristics compared with the other Bacillus strains such as pink colony colour, low growth temperature and low nutrient requirement. The results indicate that strain L5T represents a novel species of the genus Bacillus, for which the name Bacillus cavernae sp. nov. is proposed. The type strain is L5T (5KCTC 33637T5CCTCC AB 2015055T). The genus Bacillus belongs to the family Bacillaceae,order (Claus & Berkeley, 1986; Holt et al., 1994; Rheims et al., Bacillales,phylumFirmicutes, and was first proposed by 1999; Yumoto et al., 2004; Lim et al., 2007; Zhang et al., Cohn (1872) with Bacillus subtilis as the type species.
