Prediction of body weight using morphometric indices in giant African land snail (Achatina marginata) was studied for the three (3) agro-ecological zones Imo State (Owerri, Okigwe and Orlu zones). One hundred sixty (160) snails were surveyed course this study. Data generated through measurement weight, shell length, width, thickness, mouth shell, visceral, length foot thickness foot. collected ...

Fluvial systems carve the Earth's surface under influence of climate and tectonics. This process tends towards dynamic equilibrium conditions, in which rivers respond by regularizing their longitudinal profiles to a graded form. However, external forcings frequently interrupt this trend displacing system transient state from will evolve again with tendency In bedrock incising rivers, profile sh...

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...

Drainage watershed morphometry plays a major role in terms of understanding flood dynamics. Flood potentials are explained considering the linear, areal, and relief features watersheds. In general, there number geomorphometric indices description these features. The formal geometries, geomorphology, geology, general climate characteristics, etc., which play decisive potential watershed, can be ...

In the framework of the EU funded BEEP project a set of biomarkers, gross morphometric indices and tissue concentrations of selected organic pollutants were measured in flounder (Platichthys flesus) and mussels (Mytilus trossulus) collected twice a year (April and October) from three sites in the inner Gulf of Gdańsk between autumn 2001 and spring 2003. In flounder, seasonal differences in most...

Morphometric methods have been used in diatom research for decades. We present a review of the history of usage of morphometric methods of outline shape analysis, pattern recognition, and landmarkbased analysis. In addition, we present how morphometric methods are important in diatom taxonomy and classifi cation and what connections exist between morphometric methods and biologically meaningful...

Kabani river is a 7 order stream with a basin area of 1647 km. There are 4 sixth order and11 fifth order sub-basins. This analysis is mainly confined to 11 fifth order sub basins. Morphometric indices like stream ordering, bifurcation ratio, stream length, drainage density, stream frequency, form factor, elongation ratio, circularity ratio, constant of channel maintenance, asymmetry factor, sin...

The understanding of pedestrian mobility behaviors often relies on aggregated analyses. These analyses correlate spatial entities with the mobility streams that cross them. These types of approach are in particular developed to assess the impact of built morphology on pedestrian behavior. To go a bit further, we propose an unaggregated analysis, based on discrete choice models, and targeted on ...

introduction tectonic of binaloud mountain ranges is controled by thrust faults system and folds related to these faults. parts of this mountain ranges and neyshabour plain is as study area in north eastern iran and between latitudes 36° 11´ 00 to 36° 30´ 00 and longitudes 58° 35´ 00 to 59° 00´ 00. in this paper we first study morphometric indices in this area then analyze drainages and allovia...
