Landslides are a natural hazard that can endanger human life and cause severe environmental damage. A landslide susceptibility map is essential for planning, managing, preventing landslides occurrences to minimize losses. variety of techniques employed susceptibility; however, their capability differs depending on the studies. The aim research produce Langat River Basin in Selangor, Malaysia, u...

An odd perfect number, N , is shown to have at least nine distinct prime factors. If 3 N then N must have at least twelve distinct prime divisors. The proof ultimately avoids previous computational results for odd perfect numbers.

No matter where you live, how old you are or what you look like, health researchers have recently discovered that 90% of the most common cardiovascular event, the first heart attack (myocardial infarction), can be attributed to nine modifiable risk factors. The risk factors include: cigarette smoking, an abnormal ratio of blood lipids, high blood pressure, diabetes, abdominal obesity, stress, a...

The efficiency of three statistical models, AHP surface-weighted density bivariate (semi-quantitative models), stepwise multivariate regression and logistic multivariate regression models were compared in Chehel-Chai watershed in Golestan province, Iran. In current study the hazard map was prepared according to the top model of landslide hazard map. Chehel-Chai watershed is located as one of Go...

slope stability analysis is a geotechnical engineering problem characterized by many sources ofuncertainty. in slope stability computations, some of these sources are encountered, such as geologicaldetails missed in the exploration program, estimation of soil properties that are difficult to quantifyand many other relevant factors. therefore, accurate reproduction of the spatial variability in ...

We investigated the feeding sites of the Nonggang Babbler (Stachyris nonggangensis) during three time periods (July-September, 2010; November-December, 2010; January-February, 2011) in Nonggang National Nature Reserve, Guangxi, China with the line transect method and sampling method. Principal component analysis of the data identified that the feeding sites in the rainy season were dominated by...

Recent increases in deciduous shrub cover are a primary focus of terrestrial Arctic research. This study examined the historic spatial patterns of shrub expansion on the North Slope of Alaska to determine the potential for a phase transition from tundra to shrubland. We examined the historic variability of landscape-scale tall shrub expansion patterns on nine sites within river valleys in the B...
