The present study investigated the growth and survival of seedlings of Rhizophora, Avicennia, and Laguncularia raised
in three different substrates: mangrove soil, latosol, and sand. The study was
based on an entirely random ...

It is important for knowledge workers in the
business sector to have access to information on companies, countries, investment opportunities, and projects. Survey of
information finding practices of professionals
in Kuwaiti companies showed that use of web sites, internal reports, and
consulting with colleagues were preferred
approaches for finding work related information. Business professionals
also frequently used organizationa ...

This paper introduces a novelty method of using a Linear Prediction
Coefficient (LPC) filter, a digital signal processing (DSP) tool to get
accurate signal measurement in noisy mobile environment. By measuring the
received power of a mobile radio, it also measures the coverage of an area
served by several base stations. For results’ validation, the mobile received
power at user end of two Code Division Multiple Acccess-2000 (CDMA2 ...

The laminar flow in the entrance region of pipes having a circular cross
section is investigated by the use of finite element solutions to the full
Navier-Stokes equations in cylindrical coordinates. Because these solutions
cover the complete three-dimensional geometry the usual development length is
no longer a very interesting parameter as explained herein. The velocities and
pressures are determined throughout the pipe and pres ...

The temperature,
relative humidity, noise, carbon dioxide, and particulate matter (PM10)
in a public library in Sao Carlos, SP, Brazil, were monitored between May and September
2013. The building is naturally ventilated through tilted windows and doors. The PM10 concentrations
in August and September were the highest when
rainfall was ...

In this study, we carry out an assessment of the impact of urbanization on
Butare, southern Rwanda and evaluate its effect on the hydrological process at
the Migina catchment. We used data from the meteorological stations of the
Migina catchment, land-use maps of the region (obtained in 1974 and 2010) and
GIS technology in order to analyse hydrological fluctuations in Migina
catchment and the expansion of Butare town. We observed ...

In this paper, anti-synchronization of two different chaotic systems is
investigated. On the basis of Lyapunov theory, adaptive control scheme is
proposed when system parameters are unknown or uncertain; sufficient conditions
for the stability of the error dynamics are derived, where the controllers are
designed by using the sum of the state variables in chaotic systems. Numerical
simulations are performed for the Chen system and ...

The question of representations of the forest world, trees and plants in
the Caribbean literature is important in the understanding of the relationship
between man and nature. This work deals with the study of literary texts which
highlight this human-nature interaction serving as the writer’s base to
establish the legitimacy of the literary discourse. It anchors this dialogue in
reality and knowledge of the world which translates ...

The capacities of countries to cope with the
challenges presented by global environmental changes vary considerably. The increasing international relations between
countries are however bridging the gap with information transfer. Nevertheless,
this trend is also seen as a hindrance to national sovereignty and has hence
created a need to find a new framework to describe and act on the international
arena. Diffusion, a processes whi ...
