A CASE STUDY OF LUNTIAN MULTI-PURPOSE COOPERATIVE IN BARANGAY LALAIG, TIAONG, QUEZON, PHILIPPINES: A VERTICAL INTEGRATION APPROACH
The Luntian Multi-Purpose Cooperative located in Tiaong, Quezon, Philippines. The Luntian Multi-Purpose
cooperative focuses more on feed production as well as hog fattening. The LMC applied the
vertical integration to develop the cooperative. They have their members as their primary costumers of their
feeds. The cooperative’s business activity includes also meat shop, granting of production loan, micro-finance,
mobilization of saving deposits, aside from feed milling and hog fattening. Different agencies, industry
organizations and private institutions provide trainings, seminars, assistance, as well as credit for the
cooperative.The aims of the study was to determine the present and discuss a noteworthy business issue (s)
of Luntian Multipurpose Cooperative, evaluate the business environment prevailing at a particular time of
this case , assess the cooperative’s performance in terms of the four business functions , define the problem
relevant to the business issue(s) being studied. The study used primary and secondary data. Primary data
were gathered through interviews with the key personnel, managers, and other informants of the Luntian
Multipurpose Cooperative in order to obtain responses regarding the overall status of the cooperative including
its problem and plans. Secondary data were taken from files and documents, especially the history, background
information and financial statements. Other data were taken through research materials such as book,
unpublished special problems and from some government institutions. The recommendation of this research
showed that Luntian MPC should engage in establishing a communal farm as to become the primary source
of hybrid piglets that their members would raised. The alternatives solution was establishing a breeding farm
that would ask for initial investment.

Towards a Comprehensive Fueling-Controlled Theory on the Growth of Massive Black Holes and Host Spheroids
We study the relation between nuclear massive black holes and their host
spheroid gravitational potential. Using AMR numerical simulations, we analyze
how gas is transported in the nuclear (central kpc) regions of galaxies. We
study the gas fueling onto the inner accretion disk (sub-pc scale) and the star
formation in a massive nuclear disk like those generally found in
proto-spheroids (ULIRGs, SCUBA Galaxies). These sub-pc resolution simulation of
gas fueling that is mainly depleted by star formation naturally satisfy the
`M_BH - $M_virial' relation, with a scatter considerably less than the observed
one. We found a generalized version of Kennicutt-Schmidt Law for starbursts is
satisfied, in which the total gas depletion rate (dot{M}_gas = dot{M}_BH +
dot{M}_SF) is the one that scales as M_gas/t_orbital. We also found that the
`M_BH - sigma' relation is a byproduct of the `M_BH - M_virial' relation in the
fueling controlled scenario.Comment: 12 pages, figures, submited to ApJ, email: [email protected]

Elemental Abundances in M31: Alpha and Iron Element Abundances from Low-Resolution Resolved Stellar Spectroscopy in the Stellar Halo
Measurements of [Fe/H] and [/Fe] can probe the minor merging history
of a galaxy, providing a direct way to test the hierarchical assembly paradigm.
While measurements of [/Fe] have been made in the stellar halo of the
Milky Way, little is known about detailed chemical abundances in the stellar
halo of M31. To make progress with existing telescopes, we apply spectral
synthesis to low-resolution DEIMOS spectroscopy (R 2500 at 7000
Angstroms) across a wide spectral range (4500 Angstroms 9100
Angstroms). By applying our technique to low-resolution spectra of 170 giant
stars in 5 MW globular clusters, we demonstrate that our technique reproduces
previous measurements from higher resolution spectroscopy. Based on the
intrinsic dispersion in [Fe/H] and [/Fe] of individual stars in our
combined cluster sample, we estimate systematic uncertainties of 0.11 dex
and 0.09 dex in [Fe/H] and [/Fe], respectively. We apply our
method to deep, low-resolution spectra of 11 red giant branch stars in the
smooth halo of M31, resulting in higher signal-to-noise per spectral resolution
element compared to DEIMOS medium-resolution spectroscopy, given the same
exposure time and conditions. We find [/Fe] = 0.49
0.29 dex and [Fe/H] = 1.59 0.56 dex for our
sample. This implies that---much like the Milky Way---the smooth halo of M31 is
likely composed of disrupted dwarf galaxies with truncated star formation
histories that were accreted early in the halo's formation.Comment: 21 pages, 14 figures, accepted to Ap
Elemental Abundances in M31: A Comparative Analysis of Alpha and Iron Element Abundances in the the Outer Disk, Giant Stellar Stream, and Inner Halo of M31
We measured [Fe/H] and [α/Fe] using spectral synthesis of low-resolution stellar spectroscopy for 70 individual red-giant-branch stars across four fields spanning the outer disk, Giant Stellar Stream (GSS), and inner halo of M31. Fields at M31-centric projected distances of 23 kpc in the halo, 12 kpc in the halo, 22 kpc in the GSS, and 26 kpc in the outer disk are α-enhanced, with ⟨ [α/Fe]〉= 0.43, 0.50, 0.41, and 0.58, respectively. The 23 and 12 kpc halo fields are relatively metal-poor, with ⟨ [Fe/H]⟩ = −1.54 and −1.30, whereas the 22 kpc GSS and 26 kpc outer disk fields are relatively metal-rich with ⟨ [Fe/H]⟩ = −0.84 and −0.92, respectively. For fields with substructure, we separated the stellar populations into kinematically hot stellar halo components and kinematically cold components. We did not find any evidence of a radial [α/Fe] gradient along the high surface brightness core of the GSS between ~17 and 22 kpc. However, we found tentative suggestions of a negative radial [α/Fe] gradient in the stellar halo, which may indicate that different progenitor(s) or formation mechanisms contributed to the build up of the inner versus outer halo. Additionally, the [α/Fe] distribution of the metal-rich ([Fe/H] > −1.5), smooth inner stellar halo (r_(proj) ≾ 26 kpc) is inconsistent with having formed from the disruption of a progenitor(s) similar to present-day M31 satellite galaxies. The 26 kpc outer disk is most likely associated with the extended disk of M31, where its high α-enhancement provides support for an episode of rapid star formation in M31's disk possibly induced by a major merger

Hanging in there: exploring the heritability of breast cancer survival
Breast cancer is one of the leading causes of cancer death in women worldwide. Survival after diagnosis varies greatly between patients even when the tumor characteristics aresimilar. Familial studies have shown that relatives with breast cancer tend to have similar prognosis, indicating that breast cancer survival might have a heritable component. Moreover,candidate genes studies have identified prognostic roles for germline mutated genes such as BRCA1/2 and pharmacogenomic studies have explored how germline mutations might affect treatment. Nonetheless, the role of common germline variants on breast cancer survival is still unclear. In this thesis, we aimed exploring the association between common germline variants and breast cancer survival.LUMC / Geneeskund
Origin of supermassive black holes: predictions for the black hole population
The presence of supermassive black holes at redshift z > 6 raises some
questions about their formation and growth in the early universe. Due to the
construction of new telescopes like the ELT to observe and detect SMBHs, it
will be useful to derive theoretical estimates for the population and to
compare observations and model predictions in the future. In consequence our
main goal is to estimate the population of SMBHs using a semi-analytic code
known as Galacticus which is a code for the formation and evolution of galaxies
where we are about to include different scenarios for SMBHs formation
indicating the initial mass of the black hole seed, its formation conditions
and recipes for the evolution of the components of the galaxies. We found that
the principal mechanism of growing SMBHs is is via galaxy mergers and accretion
of matter. For the comparison of our results with observations, we calculate
the radius of influence of the black hole to estimate which part of the
population could be detected, leading to relations similar to the observed
ones.Comment: 3 pages, 3 figure
