A Proposed Model for Evaluating Modular Education
Introduction: Educational evaluation is one of the main elements of educational systems. It also has a particular role in different educational standards such as ISO 10015. It seems that oral and written examinations are not enough for an effective evaluation of instructions. In order to accomplish an efficient educational evaluation, an evaluation model was designed for educational assessment ...
متن کاملHydrostatic compression model for sandy soils
Based on elastic considerations, a new four parameter model of the hydrostatic compression curves of sandy soils is presented. Using a unique set of parameters, this model is capable of accurately representing the infinite family of compression curves that result when soil is subjected to stresses below particle breakage. The parameters are readily estimated from two hydrostatic tests conducted...
متن کاملANP Application in Evaluating Ecological Capability of Range Management (Case Study: Badreh Region, Ilam Province)
Rangelands are important for plant productivity, livestock production, wildlife,conservation of soil and water resources, and etc. One of the main problem of rangeland isthat has not been used based on its potential that leads to more degradation of rangelands.The purpose of this study was to evaluate the range management capability of Badrehregion in Ilam province, Iran, using ANP (Analytic Ne...
متن کاملSurface Sediments in the Marsh-Sandy Land Transitional Area: Sandification in the Western Songnen Plain, China
The development of sandification process was studied, by monitoring the changes of sediment characteristics, at marsh-sandy land intersections in China's Songnen region. A series of sediment collection plates were deployed in the region; after one year, sediments in these plates were analyzed for changes of mass and chemical characteristics. The sediment flux and the sand content of the sedimen...
متن کاملDetermination of arsenic in sandy soils.
The analysis of arsenic in soil requires a procedure which is capable of releasing microgram quantities from a complex matrix and eliminating interferences for a specific determination. Kingsley and Schaffert ( I ) have described microdetermination of arsenic in biological material, using concentrated hydrochloric acid for digesting the sample. Beard and Lyerly ( 2 ) have applied the selective ...
