BACKGROUND Originally developed for educational use, the Leadership Practice Inventory (LPI) is used to measure leadership practices in nursing research. There is limited reporting of LPI psychometric properties when used to measure leadership practices of nurses. OBJECTIVE This study aimed to investigate psychometric properties of the LPI when used to measure the leadership practices of nurs...

Few ecological studies have explored landscape suitability using the gradient concept of structure for wildlife species. Identification conditions influencing ecology endangered species allows development more robust recovery strategies. Our objectives were to (i) identify range metrics (i.e., mean patch area; and edge densities; percent land cover; shape, aggregation, largest indices) associat...

drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...

The regional ecological security and sustainable development are impacted by the changing terrain pattern. It is important to investigate temporal spatial shifts in coastal city landscape patterns As they have significant directing implications for pattern improvement. analytical results of index zone Nansha District Guangzhou investigated at three levels: patch level scale, type overall utiliz...

Satellite imagery at multiple temporal, spatial, and radiometric resolutions and spatial extents provides a unique opportunity for examining landscape-level, spatial patterns consisting of a finite set of categories mapped onto regular lattices. Landscape pattern indices (LPIs) have become increasingly popular for quantifying and characterizing various aspects of these spatial patterns. This pa...

Open geospatial data sources provide opportunities for low cost 3D scene reconstruction. In this study, based on a sparse airborne laser scanning (ALS) point cloud (0.8 points/m2) obtained from open source databases, a building reconstruction pipeline for CAD building models was developed. The pipeline includes voxel-based roof patch segmentation, extraction of the key-points representing the r...

Moringa oleifera has been used in traditional medicine to treat diabetes. However, few studies have been conducted to relate its antidiabetic properties to proteins. In this study, a leaf protein isolate was obtained from M. oleifera leaves, named Mo-LPI, and the hypoglycemic and antioxidant effects on alloxan-induced diabetic mice were assessed. Mo-LPI was obtained by aqueous extraction, ammon...

fragmentation is one of the major spatial processes leading to change in a landscape, which is described as transformation of a specific habitat or land cover to smaller patches with less connectivity and viability. construction of roads is one of the main causes of fragmentation in natural areas and habitats. presence of roads in ecologically sensitive and protected areas, leads to destruction...

any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...

The improper treatment of landfill leachates is one the major problems associated with waste landfilling and causes serious environmental pollution at sites their surroundings. To develop a suitable leachate system to minimize risk pollution, it important characterize seasonal temporal variations leachates. This study investigated quality Nam Son in Hanoi, Vietnam 2017–2019 characterized potent...
