The conservation status of birds in the Ketambe Research Station area, Gunung Leuser National Park, needs to be done so that more attention can paid preservation bird diversity. This study aims observe various three altitude zones, namely zone 1 (350-550 m asl), 2 (550-800 and 3 (800-1050 asl). Observations were made May-August 2019 at Station, Southeast Aceh. results observations as a whole, t...

The genus Centaurea L. (Asteraceae, tribe Cardueae, subtribe Centaureinae) comprises ca. 600 species distributed in Asia, Europa, North Africa and America (Hickey and King, 1981; Heywood, 1979). Turkish flora numbers 187 species, 114 of which being endemic (Davis, 1975; Davis et al., 1988; Wagenitz et al., 1988; Guner et al., 2000; Duran and Duman, 2000; Turkoglu et al., 2003). Centaurea ptosim...

Triatoma infestans is the main vector of Chagas disease in the Southern Cone countries. Wild populations of T. infestans appear widespread throughout the Andean valleys of Bolivia. In Cotapachi (2750 m asl), all sorts of rocky outcrops, regardless of their size, provided good refuges for T. infestans. Of the 1120 ecotopes investigated, 330 (29.5%) contained triatomines and 92% of the collected ...

Introduction In 1950, Maurice Herzog and Louis Lachenal became the first climbers to reach the summit of an 8000 m peak (Annapurna, 8091 m). Since that pioneering achievement, tens of thousands of mountaineers have ventured to Nepal, Pakistan, Tibet and China to climb the 14 peaks that rise above 8000 m. Some have succeeded. Some have died in the attempt. Climbing above 8000 m is a severe test ...

Arginine is a critical amino acid in specific cancer types including hepatocellular carcinoma (HCC) and melanoma. Novel molecular mechanisms and therapeutic targets in arginine metabolism-mediated cancer formation await further identification. Our laboratory has previously demonstrated that arginine metabolic enzyme argininosuccinate lyase (ASL) promoted HCC formation in part via maintenance of...

Article history: Received June 26, 2012 Received in Revised form August, 12, 2012 Accepted 15 September 2012 Available online September 17 2012 One of the primary concerns with data envelopment analysis arises when the number of inputs and outputs increases. In such a case, required computations will become time consuming and there is a concern on developing some hybrid methods to increase the ...

The study area is located ~50 km in the north of Tehran capital city, Iran, and is a part of central Alborz Mountain. The intrusive bodies aged post Eocene have intruded in the Eocene volcanic units causing hydrothermal alterations in these units. Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) images were used to map hydrothermal alteration zones. The propylitic, phyllic...

Introduction Several studies have demonstrated that DWI lesion conspicuity is related to the duration of transient ischaemic attack (TIA) symptoms [1, 2]. In minor ischaemic stroke or TIA (minS/TIA) the perfusion deficit will resolve over the time span of several days to one week [3, 4]. The relationship between a DWI lesion and perfusion deficit, however, remains controversial, motivating the ...

for the first time, an assemblage of cryptospores, which includes 10 species belonging to nine genera, from the upper ordovicianstrata, is being reported, in iran. these cryptospore assemblages were recovered from the upper part of ghelli formation., from theeastern alborz mountain range. these peri-gondwanan cryptospores have been classified based on their morphology (monad, truedyad, pseudody...
