We surveyed montane meadows in the northern Sierra Nevada and southern Cascades for two field seasons to compare commonly used aquatic and terrestrial-based assessments of meadow condition. We surveyed (1) fish, (2) reptiles, (3) amphibians, (4) aquatic macroinvertebrates, (5) stream geomorphology, (6) physical habitat, and (7) terrestrial vegetation in 79 meadows between the elevations of 1,00...

Soil salinization is a widespread and important environmental problem. We propose high-precision remote sensing identification method for saline-alkaline areas using multi-source data, which of some significance improving ecological problems on global scale have been caused by soil salinization. Its principle to identify from imagery decision tree model combining four spectral indices named NDS...

conclusions the abovementioned ivc ultrasonographic criteria for hemodynamic congestion appear clearly inconsistent. alternatively, a sequential or simultaneous combination of clinical scores of congestion, ivc ultrasonographic indices, and circulating levels of natriuretic peptides could be warranted. background among the indices able to replace invasive central venous pressure (cvp) measureme...

analytical detection of cracking in connections of steel moment resisting frames using simple damage indices is important since these cracks are not visible unless the connections are uncovered. in this paper, applicability of three cumulative damage indices for detection of cracking in a cover plate welded moment connection is investigated. the damage indices considered in this study are based...

BACKGROUND Social franchising programs in low- and middle-income countries have tried using the standard wealth index, based on the Demographic and Health Survey (DHS) questionnaire, in client exit interviews to assess clients' relative wealth compared with the national wealth distribution to ensure equity in service delivery. The large number of survey questions required to capture the wealth ...

in order to study drought tolerance indices and to introduce tolerant maize hybrids in drought conditions, an experiment was conducted at the experimental field of seed and plant improvement institute, in 2009. the experiment was carried out using split-plot in a randomized complete block design (crbd) with three replications. the main plots consisted of three levels of irrigation regimes (irri...

In this paper, a new 6-dof parallel haptic master device is proposed. Many existing haptic devices require large power due to having floating actuator and also have small workspaces. The proposed new mechanism is relatively light by employing non-floating actuators and has large workspace. Kinematic analysis and kinematic optimal design problem is performed for this mechanism. Dexterous workspa...

This paper compares the Portuguese and Bulgarian consumer price indices (CPI) and attempts to identify some areas in which the CPI compilation methodology could be improved in the two countries. This work is organised into six sections. The first section briefly describes the organisational structure on which the production of the CPI is based in the two countries. The second section focuses on...
