  • Seismicity of the Northwestern Region of Libya: An Example of Continental Seismicity
    Seismological Research Letters, 2006
    Co-Authors: Emad A. M. Al-heety, Abdurazzag A. Eshwehdi
    Abstract:

    Libya is situated on the Mediterranean foreland of the African Shield; its seismicity and tectonics reflect the geological history of the north African craton. Libya is not considered a highly active seismic Region (Gutenberg and Richter 1965). However, several earthquakes of magnitude > 6.0 have occurred in Libya during the past century. A number of authors have investigated the seismicity and seismotectonics of Libya (Seiberg 1932; Minami 1963; Gordan and Engdahl 1963; Campbell 1968; Goodchild 1968; Kebeasy 1980; Westway 1990; Suleiman and Doser 1994; Al-Heety and Eshwehdi 2004). These investigations show that seismic activity in Libya is documented back to A.D. 262 and A.D. 365, when two large events destroyed the ancient city of Cyrene. Most of the seismic activity is concentrated on the coast of the Northwestern part of Libya in the Al Jabal Al Akhdar Region. The seismicity of this coastal Region extends to the north as far as Greece. Another active seismic zone is concentrated along the eastern margin of the NW-SE trending Hun Graben. The Region offshore of Tripoli is active as well. The southern part of Libya appears to be largely aseismic. In previous investigations of seismicity in Libya, all data were collected from international sources such as the National Earthquake Information Center (NEIC), the International Seismological Centre (ISC), the European-Mediterranean Seismological Centre (EMSC), and the bulletins of the national networks ( e.g. , those in southern Europe, Egypt, Tunisia, and others). Until very recently, there has been no national seismic network; the Libyan Seismological Network began operation in early 2006. This study represents the first attempt to study the seismicity of Libya using records of a local seismic station, Gharyan station. (Gharyan station data are available from the office of the Libyan Seismological Observatory and are available …

  • Analysis of deletional damage in SMN1, SMN2, and NAIP genes in patients with spinal muscular atrophy in the Northwestern Region of Russia
    Genetika, 2001
    Co-Authors: Andrey Sergeyevich Glotov, A. V. Kiselev, T. E. Ivashchenko, V. S. Baranov
    Abstract:

    Polymerase chain reaction with subsequent SSCP (single-strand DNA conformational polymorphism) and restriction (BselI restriction endonuclease) analyses were used to type the DNA samples of affected individuals and their relatives from 23 Russian families with high risk of spinal muscular atrophy (SMA) residing in the Northwestern Region of Russia. Deletions of exon 7 of the SMN gene were found in 96% of the individuals examined. The frequency of homozygous deletion of exons 7 and 8 of the SMN1 gene was 65%. The frequency of homozygous isolated deletion of the SMN1 gene exon 7 among the SMA patients was 4.3%. Homozygous deletion of exon 5 of the NAIP gene was found in 22% of SMA patients. In SMA patients, a total of seven deletion types involving the SMN1, NAIP, and SMN2 genes were detected. Deletion of exons 7 and 8 of the SMN1 gene was the most common mutation associated with SMA in patients from the Northwestern Russia.

  • Crop Raiding Behaviour of Elephants in the Northwestern Region of Sri Lanka
    2012
    Co-Authors: H. S. Haturusinghe, Devaka Weerakoon, Sri Lanka
    Abstract:

    The north-western Region of Sri Lanka offers a unique conservation problem with respect to elephants. Unlike all other elephant inhabited areas of Sri Lanka, this Region has the lowest coverage in the protected area network (Fig. 1). With the exception of the Wilpattu National Park, the total extent of all the other protected areas in this Region amounts less than 31,000 ha. Therefore, none of these protected areas are large enough to support a viable wild elephant population. However, a fairly substantial elephant population resides in this area. A census carried out by the Department of Wildlife Conservation (DWC) revealed that there are at least 591 elephants inhabiting the north-western Region (Hendavitharana et al. 1993). However, de Silva & Attapattu (1997) reported that this number could be as high as 1500 elephants. Fernando et al. (2011) estimate the present elephant population in this Region to be more than 1000 elephants.

  • Feeding Behaviour of Asian Elephants in the Northwestern Region of Sri Lanka
    2007
    Co-Authors: K. A. P. Samansiri, Devaka Weerakoon, Sri Lanka
    Abstract:

    Materials and methods Study area: The study area is located in the Northwestern Region of Sri Lanka encompassing the Mahaweli system H and adjoining areas. The study area is demarcated by the towns of Puttalam in the East, Mahawa in the South, Habarana in the West, and Anuradhapura in the North. The extent of the study area is approximately 3000 km 2 and includes 15 administrative divisions. Human use patterns found within the study area can be grouped into three categories as, low use, high use and very high use.
