Geomorphic position often correlates with nutrient cycling across landscapes. In tropical forests, topography is known to influence phosphorus (P) availability, but its effect on nitrogen (N) cycling has received less exploration, especially in lowland forests where widespread N richness is frequently assumed. Here, we report significant effects of topographic slope and landscape position on mu...
Submitted to the Texas Water Development Board 2 PREFACE This report is submitted in fulfillment of contract no. 2005-483-564 between the Texas Water Development Board and Jonathan Phillips (doing business as Copperhead Road Geoscience). The report is presented in two more-or-less independent parts, reflecting the Scope of Work for the project. The first is a review and evaluation of geomorphic...
Background and purpose: Finding a suitable location for the solid wastes is necessary for urban development projects. The Gonad city with a population of 131 108 people will produce 120 tons of garbage per day. This amount of wastes is buried in two temporary sites (adjacent of the river) and a permanent. Wastes leachate infiltration into the ground water river cause pollution and other environ...
in this study, scour of mashkid bridge pier located in mashkid river of saravan county has been studied and to measure the scour rate, the numerical model hec-ras 4.0 has been used. upon selection of mashkid river as the case study and whereas the studied zone is important with respect to the climatic conditions and showery monsoon raining and flowing the great and destructive floodwaters, ther...
BACKGROUND Highly productive hotspots in the ocean often occur where complex physical forcing mechanisms lead to aggregation of primary and secondary producers. Understanding how hotspots persist, however, requires combining knowledge of the spatio-temporal linkages between geomorphology, physical forcing, and biological responses with the physiological requirements and movement of top predator...
PURPOSE To investigate the tilt and decentration of the crystalline lens and the intraocular lens (IOL) relative to the corneal topographic axis using anterior segment ocular coherence tomography (AS-OCT). METHODS A sample set of 100 eyes from 49 subjects (41 eyes with crystalline lenses and 59 eyes with IOLs) were imaged using second generation AS-OCT (CASIA2, TOMEY) in June and July 2016 at...
PURPOSE To evaluate the influences of 27-gauge vitrectomy on corneal topographic conditions. METHOD Fifty-six eyes of 56 patients undergoing 27-gauge vitrectomy were retrospectively studied. Twenty-three eyes with epiretinal membrane (ERM), 23 eyes with macular hole (MH), and 10 eyes with proliferative diabetic retinopathy (PDR) were included. Forty-five of the 56 eyes underwent 27-gauge phac...

Takes Qinghai-Tibet Plateau as a research field, this paper based on the models and algorithms, completes the numerical information extraction of periglacial geomorphology distribution by using SRTM-DEM and annual mean temperature data. Based on the extracted results and remote sensing images, the periglacial geomorphology distribution in Qinghai-Tibet Plateau is achieved by visual interpretati...
