oligochaeta worms are important organisms in aquatic ecosystem. their omnipresence makes them as an indicator of environmental changes and health of aquatic ecosystem. the members of the family tubificidae and in particular, genus limnodrilus are considered as the most tolerant oligochaets to aquatic pollution. therefore identification and biological characteristics of this taxon are of great h...

The study material contains the data on boys and girls aged from 6 to 18 years collected in the course of the Third and Fourth Anthropological Surveys carried out in Poland in 1977/78 and 1987/88. The questionnaire data (father’s and mother’s education and number of children in the family) were supplemented with the results of measurements of the triceps skinfold. It is assumed that the triceps...

An ongoing question remains for family researchers: Why does a positive association between cohabitation and marital dissolution exist when one of the primary reasons to cohabit is to test relationship compatibility? Drawing on recently collected data from the 2006 - 2008 National Survey of Family Growth, the authors examined whether premarital cohabitation experiences were associated with mari...

OBJECTIVE Evaluate the Glasgow outcome scale (GOS) at discharge (GOS-HD) as a prognostic indicator in patients with traumatic brain injury (TBI). METHOD Retrospective data were collected of 45 patients, with Glasgow coma scale <8, age 25±10 years, 36 men, from medical records. Later, at home visit, two measures were scored: GOS-HD (according to information from family members) and GOS LATE (1...

Ulam's method of discretising the dynamics of a smooth deterministic system to produce a nite state Markov chain approximation has been in use for over two decades. We review what can be done with the constructions, in the sense of how various dy-namical indicators and behaviour can be numerically extracted.

The Malcolm horizon (Malcolm, et. al., 1975) utilizes a large projected light stimulus (PVHD) as an attitude indicator in order to achieve a more compelling sense of roll than is obtained with smaller devices. The basic principle is that the larger stimulus is more similar to visibility of a real horizon during roll, and does not require fixation and attention to the degree that smaller display...

Aircraft engine manufacturers collect large amount of engine related data during flights. These data are used to detect anomalies in the engines in order to help companies optimize their maintenance costs. This article introduces and studies a generic methodology that allows one to build automatic early signs of anomaly detection in a way that is understandable by human operators who make the f...

Very high resolution satellite images are used to derive the spatial distributions of landscape ecological metrics within suburban areas. These indicators are weighted mean patch size and lacunarity computed from thresholded normalized difference vegetation index obtained from multispectral IKONOS-2 imagery. Spatial distributions of the metrics are derived for an extensive suburban area on the ...

With the emphasis on self-directed learning (SDL) and learner-controlled instruction (LCI) the author looks into the mechanism that has made several business and industrial sectors in the Western world progress significantly in the training and development field. The achievement of this strategy as compared to the traditional training of time-based rotation has made several organizations follow...

The sustainable organizational change has an ever increasing importance, leading to the rethinking of the management and systems of performance measurement and monitoring within the companies. As a reaction to current economic phenomena, in the first section of this work we tried to bring out the need for using the couple Balanced Scorecard Corporate Social Responsibility by companies. Thus, co...
