The main purpose of this paper is to investigate the stiffness of soils under cyclic loading at small and medium strain level. The influence of some important factors on the shear modulus of soils such as: the strain level, the plasticity index and the mean effective stress are discussed in detail. Behaviour of different kind of soils is also compared based on available laboratory data includin...

Using Tagalog as a case study, this paper provides an analysis of a cross-linguistically well attested phenomenon, namely, cases in which a bare NP’s syntactic position is linked to its interpretation as definite or indefinite. Previous approaches to this phenomenon, including analyses of Tagalog, appeal to specialized interpretational rules like Diesing’s Mapping Hypothesis. I argue that such ...

Soil transplant serves as a proxy to simulate climate changes. Recently, we have shown that southward transplant of black soil and northward transplant of red soil altered soil microbial communities and biogeochemical variables. However, fundamental differences in soil types have prevented direct comparison between southward and northward transplants. To tackle it, herein we report an analysis ...

The rapid expansion of deserts in recent decades as a result of human actions combined with climatic changes has highlighted the necessity to understand biological processes in arid environments. Whereas physical processes and the biology of flora and fauna have been relatively well studied in marginally used arid areas, knowledge of desert soil micro-organisms remains fragmentary. The objectiv...

In this article, are analyzed the processes of desertification in Region Planning and Management Waters Macururé Curaçá Rivers. The mapping land use, through photointerpretation images RapidEye, allowed to verify that anthropized Caatinga, Caatinga park Agriculture occupy more than half region show decline vegetation resilience. These areas natural pastures support extensive herds whose overgra...

This research selects two study areas with different urban developments, sizes, and spatial patterns to explore the suitable methods for mapping impervious surface distribution using Quickbird imagery. The selected methods include per-pixel based supervised classification, segmentation-based classification, and a hybrid method. A comparative analysis of the results indicates that per-pixel base...

Although marigold (Tagetes patula) is known to produce allelopathic compounds toxic to plant-parasitic nematodes, suppression of Meloidogyne incognita can be inconsistent. Two greenhouse experiments were conducted to test whether marigold is more effective in suppressing Meloidogyne spp. when it is active rather than dormant. Soils infested with Meloidogyne spp. were collected and conditioned i...
