Testo completoThis study aims to show that the principles of Earth Charter can be embedded in social responsibility practices adopted by agribusinesses companies, located in the Ceara‟s country area. Through Corporate Social Responsibility (CSR), many of the social responsible practices are directly and indirectly linked to values and principles of this declaration. The Earth Charter is the main instrument of this recent initiative to promote the transition to a global society based on a model of shared ethics, which includes respect and care for the community of life, ecological integrity, democracy and a culture of peace. It brings more comprehensive and broader concept of social responsibility to businesses by providing them universal elements structured to recognize their role in humanity. For this, we evaluated the performance of a social responsible agribusinesses company Unit from Group 3 Hearts in EuzÃbio - CearÃ. We used primary source data obtained through a questionnaire and secondary source data drawn mainly from the International Earth Charter. The social responsible practices proposed were analyzed according to the Ethos and the principles and pillars of the Earth Charter. Those were evaluated through the EC-Assess methodology, which enabled them to establish several levels of implementation and levels of recovery of those practices in business. The agribusinesses company has demonstrated a social responsible regarding the implementation and enhancement at various levels of suggested actions. Thus, it was possible to see what is feasible, through responsible management, entering the Earth Charter in the agroindustrial sector and generate gains for all public relations, especially in rural areas, where deprivation reinforce the role of agribusiness as promoters growth and development and maximize its impact in improving the quality of life for this population.

The Lower Charles River has been a heavily utilized urban river that runs between Cambridge and Boston in Massachusetts. The recreational usage of the river is dependent on adequate water depths and there have been no definitive prior studies on the sedimentation rate of the Lower Charles River. The river transitioned from tidal to a freshwater basin in 1908 and the study area for historical comparisons was from the old Charles River Dam to the Boston University Bridge. This study surveyed the river, digitized three prior surveys that spanned 114 years, calculated volumes and depth distributions for each survey, and estimated sedimentation rates from fits to the volumes over time. The average sedimentation rate is estimated as 5-10 mm/year, which implies 1.8-3.5 feet sedimentation since 1908. Sedimentation rates and distributions are necessary to develop comprehensive management plans for the river.

Testo completosource region associated with mesospheric dusty space plasmas may be modulated by radio wave heating with ground-based ionospheric heating facilities. These experiments show great promise as a diagnostic for the associated dusty plasma in the Near-Earth Space Environment which is believed to have links to global change. This provides an alternative to more complicated and costly space-based observational approaches to investigating these layers. This dissertation seeks to develop new analytical and computational models to investigate fundamental physics of the associated dusty plasmas as well as utilize experimental observations during High Frequency HF ground-based heating experiments to develop practical techniques for diagnosing these dusty plasma layers.
The dependency of the backscattered signal strength (i.e. Polar Mesospheric Summer Echoes PMSEs) after the turn-on and turn-off of the radio wave heating on the radar frequency is an unique phenomenon that can shed light on the unresolved issues associated with the basic physics of the natural charged mesospheric dust layer. The physical process after turn-on and turn-off of radio wave heating is explained by competing ambipolar diffusion and dust charging processes. The threshold radar frequency and dust parameters for the enhancement or suppression of radar echoes after radio wave heating turn-on are investigated for measured mesospheric plasma parameters. The effect of parameters such as the electron temperature enhancement during radiowave heating, dust density, dust charge polarity, ion-neutral collision frequency, electron density and dust radius
on the temporal evolution of electron irregularities associated with PMSE is investigated.
The possibility of observing the turn-on overshoot (enhancement of radar echoes after the
radiowave turn-on) in the high frequency HF radar band is discussed based on typical mesospheric
parameters. It has been shown that predicted enhancement of electron irregularity
amplitude after heater turn-on at HF band is the direct manifestation of the dust charging
process in the space. Therefore further active experiments of PMSEs should be pursued
at HF band to illuminate the fundamental charging physics in the space environment to
provide more insight on this unique medium. Preliminary observation results of HF PMSE
heating experiment with the new 7.9 MHz radar at the European Incoherent Scatter EISCAT
facility appear promising for the existence of PMSE turn-on overshoot. Therefore, future
experimental campaigns are planned to validate these predictions.
Computational results are used to make predictions for PMSE active modification experiments at 7.9, 56, 139, 224 and 930MHz corresponding to existing ionospheric heating facilities. Data from a 2009 very high frequency VHF (224 MHz) experiment at EISCAT
is compared with the computational model to obtain dust parameters in the PMSE. The
estimated dust parameters as a result of these comparison show very reasonable agreement to dust radius and density at PMSE altitudes measured during a recent rocket experiment providing validation to the computational model.
The first comprehensive analytical model for the temporal evolution of PMSE after heater
turn-on is developed and compared to a more accurate computational model as a reference.
It is shown that active PMSE heating experiments involving multiple observing frequencies
at 7.9 (HF), 56, and 224 MHz (VHF) may contribute further diagnostic capabilities since
the temporal evolution of radar echoes is substantially different for these frequency ranges.
It is shown that conducting PMSE active experiments at HF and VHF band simultaneously
may allow estimation of the dust density altitude profile, dust charge state variation during
the heating cycle, and ratio of electron temperature enhancement in the irregularity source
region. These theoretical and computational models are extended to study basic physics of the evolution of relevant dusty plasma instabilities thought to play an important role in irregularity production in mesospheric dust layers. A key focus is the boundary layer of these charged dust clouds. Several aspects of the cloud\'s structure (thickness of boundary layer, average particle size and density, collisional processes, and cloud expansion speed) and the ambient plasma are varied to determine the effect of these quantities on the resulting irregularities.
It was shown that for high collision frequencies, the waves may be very weakly excited (or
even quenched) and confined to the boundary layer. The excited dust acoustic waves inside
the dust cloud with frequency range of 7-15Hz and in the presence of electron bite-outs is
consistent with measured low frequency waves near 10 Hz by sounding rocket experiments
over the past decade. The observed radar echoes associated with the artificially created dust
clouds at higher altitudes in the ionosphere including space shuttle exhaust and upcoming
active space experiments in which localized dust layers will be created by sounding rockets
could be related to the excited acoustic waves predicted.
Finally, variation of spatial structures of plasma and dust (ice) irregularities in the PMSE
source region in the presence of positively charged dust particles is investigated. The correlation and anti-correlation of fluctuations in the electron and ion densities in the background plasma are studied considering the presence of positive dust particle formation. Recent rocket payloads have studied the properties of aerosol particles within the ambient plasma environment in the polar mesopause region and measured the signature of the positively charged particles with number densities of (2000 cm"3) for particles of 0.5-1 nm in radius.
The measurement of significant numbers of positively charged aerosol particles is unexpected from the standard theory of aerosol charging in plasma. Nucleation on the cluster ions is one of the most probable hypotheses for the positive charge on the smallest particles. The utility being that it may provide a test for determining the presence of positive dust particles.
The results of the model described show good agreement with observed rocket data. As an
application, the model is also applied to investigate the electron irregularity behavior during
radiowave heating assuming the presence of positive dust particles. It is shown that the
positive dust produces important changes in the behavior during Polar Mesospheric Summer Echo PMSE heating experiments that can be described by the fluctuation correlation and anti-correlation properties.
The second part of this dissertation is dedicated to Stimulated Electromagnetic Emissions SEEs produced by interaction of high power electromagnetic waves in the ionosphere. Nearearth ionospheric plasma presets a neutral laboratory for investigation of nonlinear wave phenomena in plasma which can not be studied in the laboratory environment due to the effect of physical boundary conditions. This process has been of great interest due to the
important diagnostic possibilities involving ability to determine mass of constitutive ions in
the interaction region through measurements of various gyro-frequencies. Objectives include
the consideration of the variation of the spectral behavior under pump power, proximity to
the gyro-harmonic frequency, and beam angle. Also, the relationship between such spectral
features and electron acceleration and creation of plasma irregularities was an important
focus.
Secondary electromagnetic waves excited by high power electromagnetic waves transmitted
into the ionosphere, commonly know as Stimulated Electromagnetic Emissions SEEs,
produced through Magnetized Stimulated Brillouin Scatter MSBS are investigated. Data
from two recent research campaigns at the High Frequency Active Auroral Research Program
facility HAARP is presented in this work. These experiments have provided additional
quantitative interpretation of the SEE spectrum produced by MSBS to yield diagnostic measurements of the electron temperature in the heated ionosphere. SEE spectral emission lines corresponding to ion acoustic IA and electrostatic ion cyclotron EIC modes were observed with a shift in frequency up to a few tens of Hz from radio waves transmitted near the third harmonic of the electron gyro-frequency 3fce. The threshold of each emission line has been measured by changing the pump wave amplitude. The experimental results aimed to show the threshold for transmitter power to excite IA waves propagating along the magnetic field lines as well as for EIC waves excited at oblique angles relative to the background magnetic field. A full wave solution has been used to estimate the amplitude of the electric field at the interaction altitude. The estimated growth rate using the theoretical model is compared with the threshold of MSBS lines in the experiment and possible diagnostic information for the background ionospheric plasmas is discussed. Simultaneous formation of artificial field aligned irregularities FAIs and suppression of the MSBS process is investigated. Recently, there has been significant interest in ion gyro-harmonic structuring the Stimulated Electromagnetic Emission SEE spectrum due to the potential for new diagnostic information available about the heated volume and ancillary processes such as creation of artificial ionization layers. These relatively recently discovered emission lines have almost exclusively been studied for second electron gyro-harmonic heating. The first extensive systematic investigations of the possibility of these spectral features for third electron gyro-harmonic heating are provided here. Discrete spectral features shifted from the transmit frequency ordered by harmonics of the ion gyro-frequency were observed for third electron gyro-harmonic heating for the first time at a recent campaign at a High Frequency Active Auroral Research Program Facility HAARP. These features were also closely correlated with a broader band feature at a larger frequency shift from the transmit frequency known as the Downshifted Peak DP. The power threshold of these spectral features was measured, as well as their behavior with heater
beam angle, and proximity of the transmit frequency to the third electron gyro-harmonic frequency. Comparisons were also made with similar spectral features observed during 2nd
electron gyro-harmonic heating during the same campaign. A theoretical model is provided
that interprets these spectral features as resulting from parametric decay instabilities in
which the pump field ultimately decays into high frequency upper hybrid/electron Bernstein
and low frequency neutralized ion Bernstein IB and/or obliquely propagating ion acoustic
waves at the upper hybrid interaction altitude. Coordinated optical and SEE observations
were carried out in order to provide a better understanding of electron acceleration and precipitation
processes. Optical emissions were observed associated with SEE gyro-harmonic
features for pump heating near the second electron gyro-harmonic during the campaign. The
observations affirm strong correlation between the gyro-structures and the airglow.
