Charged Particle-like Branes in ABJM: A Summary
We study the effect of adding lower dimensional brane charges to the 't Hooft
monopole, di-baryon and baryon vertex configurations in AdS_4 x CP^3. We show
that these configurations capture the background fluxes in a way that depends
on the induced charges, requiring additional fundamental strings to cancel the
worldvolume tadpoles. The dynamics reveal that the charges must lie inside some
interval, a situation familiar from the baryon vertex in AdS_5 x S^5 with
charges. For the baryon vertex and the di-baryon the number of fundamental
strings must also lie inside an allowed interval. Some ideas about the
existence of these bounds in relation to the stringy exclusion principle are
given.Comment: 6 pages. Contribution to the proceedings of the XVIth European

Hints of 5d Fixed Point Theories from Non-Abelian T-duality
In this paper we investigate the properties of the putative 5d fixed point
theory that should be dual, through the holographic correspondence, to the new
supersymmetric AdS(6) solution constructed in Lozano et al. This solution is
the result of a non-Abelian T-duality transformation on the known
supersymmetric AdS(6) solution of massive Type IIA. The analysis of the charge
quantization conditions seems to put constraints on the global properties of
the background, which, combined with the information extracted from considering
probe branes, suggests a 2-node quiver candidate for the dual CFT.Comment: v2, typos corrected, comments added, to appear in JHE
Supersymmetric AdS_6 via T-duality
We present a new supersymmetric AdS_6 solution of type IIB supergravity with
SU(2) isometry. Through the AdS/CFT correspondence, this has potentially very
interesting implications for 5d fixed point theories. This solution is the
result of a non-Abelian T-duality on the known supersymmetric AdS_6 solution of
massive IIA. The SU(2) R-symmetry is untouched, leading to sixteen supercharges
and preserved supersymmetry.Comment: 4 pages, published versio
Managing watersheds to achieve people-centered water and environmental sanitation
This paper clearly illustrates the experience of the Philippine Watershed Management Coalition (PWMC) in promoting
on-ground people-centered watershed management which could be an important input towards the realization of a people
centered water and environmental sanitation. It is intended to share first hand experiences on collaborative efforts among
watershed stakeholders in the area of advocacy and capacity building as a means of achieving watershed management
at the same time moving towards water resources protection/conservation and environmental sanitation. It also stresses
the importance of making watershed management a people-focused approach
