Women Fighting Poverty in Cameroon: A Legal Perspective!
Poverty in Sub Saharan Africa has many causes, which range from the impact of the Structural Adjustment Programs, the huge foreign debt and policies that encourage mismanagement of state resources. This growing poverty and underdevelopment has attracted the attention of the international community to pursue programs aimed at attaining the UN Millennium Development Goals, foreign debt relief and increased development aid. During the introduction of policies that brought about economic hardship, African women were not consulted and their voices were not heard. Yet it is these women who feel most of the impact of these policies. During the period of the economic crisis, women did not remain silent in the face of the growing poverty. As a response, they organized themselves into groups for financial and self-help purposes. These organized women’s groups if legally and financially empowered will contribute a great deal in the fight against poverty in Cameroon. Micro financing is an important tool common in these groups, but it must be supported by the provision of basic resources and infrastructure. Women make up more than75% of subsistence farmers and are mostly found in the informal sector, their contribution helps to sustain the economy greatly, but it is still insufficient to make any significant improvement in their living standards. The inhibition stems from traditional and cultures practices that hinder women from claiming equal ownership and equal representation in decision-making settings. Hence, a good economic regulatory framework by any government fighting poverty should incorporate the economic and legal empowerment of women and target mostly rural women and their basic needs
Critical velocity for superfluid flow across the BEC-BCS crossover
Critical velocities have been observed in an ultracold superfluid Fermi gas
throughout the BEC-BCS crossover. A pronounced peak of the critical velocity at
unitarity demonstrates that superfluidity is most robust for resonant atomic
interactions. Critical velocities were determined from the abrupt onset of
dissipation when the velocity of a moving one dimensional optical lattice was
varied. The dependence of the critical velocity on lattice depth and on the
inhomogeneous density profile was studied
Mapping functions and critical behavior of percolation on rectangular domains
The existence probability and the percolation probability of the
bond percolation on rectangular domains with different aspect ratios are
studied via the mapping functions between systems with different aspect ratios.
The superscaling behavior of and for such systems with exponents

Lett. \textbf{93}, 190601 (2004)] can be understood from the lower order

determined mapping functions and , respectively.Comment: 17 pages with 6 figure
Influence of Promoter Type on Bimetallic Co-Ni/Al 2O3 Catalyst for Steam Reforming of Glycerol
Biodiesel is produced from a variety of renewable sources including waste cooking oil. However, its production has led to a glut of glycerol (a by-product, in the amount of 1 mol of glycerol for every three of fatty acid methyl esters). Glycerol presently has low-level and limited use in pharmaceuticals production. The present work deals with steam reforming of glycerol over a bimetallic Co-Ni/Al2O3 catalyst system promoted by 2.5wt% alkaline earth oxides (AEO) and lanthanide oxides (LO). The addition of metal oxide from these two groups reportedly minimizes carbon deposition with possible improvement in product selectivity and syngas production rate. Our objective was to provide a systematic correlation between physicochemical properties of the promoted catalyst and reaction metrics
The intermediate evolution phase in case of truncated selection
Using methods of statistical physics, we present rigorous theoretical
calculations of Eigen's quasispecies theory with the truncated fitness
landscape which dramatically limits the available sequence space of a
reproducing quasispecies. Depending on the mutation rates, we observe three
phases, a selective one, an intermediate one with some residual order and a
completely randomized phase. Our results are applicable for the general case of
fitness landscape.Comment: 8 page
Geometry, thermodynamics, and finite-size corrections in the critical Potts model
We establish an intriguing connection between geometry and thermodynamics in
the critical q-state Potts model on two-dimensional lattices, using the q-state
bond-correlated percolation model (QBCPM) representation. We find that the
number of clusters of the QBCPM has an energy-like singularity for q different
from 1, which is reached and supported by exact results, numerical simulation,
and scaling arguments. We also establish that the finite-size correction to the
number of bonds, has no constant term and explains the divergence of related
quantities as q --> 4, the multicritical point. Similar analyses are applicable
to a variety of other systems.Comment: 12 pages, 6 figure
