Improving water productivity, reducing poverty and enhancing equity in mixed crop-livestock systems in the Indo-Gangetic Basin
The âImproving water productivity, reducing poverty and enhancing equity in mixed crop-livestock systems in the Indo-Gangetic Basinâ
was designed and conducted by the International Water Management Institute (IWMI),
in partnership with international and national partners, to address the relative neglect of
livestock water needs of crop-livestock farming systems.
The primary objective of this project was to optimize the productive use of water in the
crop-livestock farming systems of semi-arid areas to enhance livelihoods, reduce
poverty, contribute to gender equity, and protect the environment. This was addressed
through an integrated approach led by a multi-disciplinary team across three States of
the Ganga Basin
Mining metrics for buried treasure
The same but different: That might describe two metrics. On the surface
CLASSI may show two metrics are locally equivalent, but buried beneath one may
be a wealth of further structure. This was beautifully described in a paper by
M.A.H. MacCallum in 1998. Here I will illustrate the effect with two flat
metrics -- one describing ordinary Minkowski spacetime and the other describing
a three-parameter family of Gal'tsov-Letelier-Tod spacetimes. I will dig out
the beautiful hidden classical singularity structure of the latter (a structure
first noticed by Tod in 1994) and then show how quantum considerations can
illuminate the riches. I will then discuss how quantum structure can help us
understand classical singularities and metric parameters in a variety of exact
solutions mined from the Exact Solutions book.Comment: 16 pages, no figures, minor grammatical changes, submitted to

Effects of Replacing Soybean (Glycine Max) with Fermented Sickle Pod (Senna Obtusifolia) on the Productive Performance and Carcass Characteristics of Domestic Rabbits
An experiment was conducted for 56 days to determine the productive performance and carcass characteristics of
domestic rabbits fed fermented Senna obtusifolia seed meal (FSOSM)-based diets. A control soybean meal-based diet and diets containing 0, 25, 50, 75 and 100% FSOSM as a replacement for soybean were formulated for the study. Twenty (20) domestic growing rabbits with an initial weight range of 605.25 â 662.75 g were randomly allotted to the five dietary treatments in a Completely Randomized Block Design with four replicates of one rabbit each. The productive performance was not significantly (P < 0.05) influenced by the diets. The daily weight gain ranged from 11.11 â 12.09 g/d, total weight gain 622.16 â 677.01 g/d, daily feed intake 55.15 â 61.41 g and feed conversion ratio ranged from 4.83 â 5.02. The carcass characteristics were similarly not affected (P < 0.05) by the dietary treatments. Dressing percentage ranged from 50.05 â 59.70% and retail cuts for shoulder, rack, loin and thigh were 17.73 â 18.99, 5.20 â 6.28, 13.26 â 14.17 and 20.28 â 22.33 percent body weight. It was concluded from this study that replacement of soybean with FSOSM up to 100% had no adverse effects on the productive parameters and carcass characteristics of domestic rabbits
On Traversable Lorentzian Wormholes in the Vacuum Low Energy Effective String Theory in Einstein and Jordan Frames
Three new classes (II-IV) of solutions of the vacuum low energy effective
string theory in four dimensions are derived. Wormhole solutions are
investigated in those solutions including the class I case both in the Einstein
and in the Jordan (string) frame. It turns out that, of the eight classes of
solutions investigated (four in the Einstein frame and four in the
corresponding string frame), massive Lorentzian traversable wormholes exist in
five classes. Nontrivial massless limit exists only in class I Einstein frame
solution while none at all exists in the string frame. An investigation of test
scalar charge motion in the class I solution in the two frames is carried out
by using the Plebanski-Sawicki theorem. A curious consequence is that the
motion around the extremal zero (Keplerian) mass configuration leads, as a
result of scalar-scalar interaction, to a new hypothetical "mass" that confines
test scalar charges in bound orbits, but does not interact with neutral test
particles.Comment: 18 page
A distinct adipose tissue gene expression response to caloric restriction predicts 6-mo weight maintenance in obese subjects
BACKGROUND:
Weight loss has been shown to reduce risk factors associated with cardiovascular disease and diabetes; however, successful maintenance of weight loss continues to pose a challenge.
OBJECTIVE:
The present study was designed to assess whether changes in subcutaneous adipose tissue (scAT) gene expression during a low-calorie diet (LCD) could be used to differentiate and predict subjects who experience successful short-term weight maintenance from subjects who experience weight regain.
DESIGN:
Forty white women followed a dietary protocol consisting of an 8-wk LCD phase followed by a 6-mo weight-maintenance phase. Participants were classified as weight maintainers (WMs; 0-10% weight regain) and weight regainers (WRs; 50-100% weight regain) by considering changes in body weight during the 2 phases. Anthropometric measurements, bioclinical variables, and scAT gene expression were studied in all individuals before and after the LCD. Energy intake was estimated by using 3-d dietary records.
RESULTS:
No differences in body weight and fasting insulin were observed between WMs and WRs at baseline or after the LCD period. The LCD resulted in significant decreases in body weight and in several plasma variables in both groups. WMs experienced a significant reduction in insulin secretion in response to an oral-glucose-tolerance test after the LCD; in contrast, no changes in insulin secretion were observed in WRs after the LCD. An ANOVA of scAT gene expression showed that genes regulating fatty acid metabolism, citric acid cycle, oxidative phosphorylation, and apoptosis were regulated differently by the LCD in WM and WR subjects.
CONCLUSION:
This study suggests that LCD-induced changes in insulin secretion and scAT gene expression may have the potential to predict successful short-term weight maintenanc
Adsorption of Reactive Particles on a Random Catalytic Chain: An Exact Solution
We study equilibrium properties of a catalytically-activated annihilation reaction taking place on a one-dimensional chain of length () in which some segments (placed at random, with mean concentration
) possess special, catalytic properties. Annihilation reaction takes place,
as soon as any two particles land onto two vacant sites at the extremities
of the catalytic segment, or when any particle lands onto a vacant site on
a catalytic segment while the site at the other extremity of this segment is
already occupied by another particle. Non-catalytic segments are inert with
respect to reaction and here two adsorbed particles harmlessly coexist. For
both "annealed" and "quenched" disorder in placement of the catalytic segments,
we calculate exactly the disorder-average pressure per site. Explicit
asymptotic formulae for the particle mean density and the compressibility are
also presented.Comment: AMSTeX, 27 pages + 4 figure

Inclusive pion double charge exchange on Oxygen(16) at 0.6-1.1 GeV
The inclusive pion double charge exchange (DCX) on oxygen nuclei has been
measured in the region where additional pion production is kinematically
forbidden. The experiment was performed at ITEP PS at incident pi- kinetic
energies T_0= 0.59, 0.75 and 1.1 GeV. The integrated forward differential cross
section was found to decrease with energy slowly. At 1.1 GeV it exceeds the
theoretical prediction within the conventional sequential single charge
exchange mechanism with a neutral pion in the intermediate state (Glauber
elastic rescattering) by about half an order of magnitude. The sequential
mechanism with two pions in the intermediate state (Glauber inelastic
rescatterings), which was proposed recently, seems to be able to explain the
observed slow energy dependence and allows to predict the DCX cross section for
higher energies.Comment: 27 pages, 13 figures. Minor corrections, one figure added. Accepted

Drug Attitude and Adherence: A Qualitative Insight of Patients with Hypertension
The study is aimed to explore the perceptions and experiences of hypertensive patients toward medication use and adherence. The study was qualitative in nature conducted at Sandamen Provisional Hospital of Quetta city, Pakistan; a public hospital catering to the health needs of about 40% of the population. A qualitative approach was used to gain an in-depth knowledge of the issues. Sixteen patients were interviewed, and the saturation point was achieved after the 14th interview. All interviews were audio-taped, transcribed verbatim, and were then analyzed for thematic contents by the standard content analysis framework. Thematic content analysis yielded five major themes. (1) Perceived benefits and risks of medications, (2) physician's interaction with patients, (3) perception toward traditional remedies, (4) layman concept toward medications, and (5) beliefs toward hypertension and its control. The majority of the patients carried specific unrealistic beliefs regarding the long-term use of medication; yet these beliefs were heavily accepted and practiced by the society. The study indicated a number of key themes that can be used in changing the beliefs and experiences of hypertensive patients. Physician's attitude, patient's past experiences, and knowledge related to hypertension were noted as major contributing factors thus resulting in nonadherence to therapy prescribed
Measurement of the polarisation of W bosons produced with large transverse momentum in pp collisions at sqrt(s) = 7 TeV with the ATLAS experiment
This paper describes an analysis of the angular distribution of W->enu and
W->munu decays, using data from pp collisions at sqrt(s) = 7 TeV recorded with
the ATLAS detector at the LHC in 2010, corresponding to an integrated
luminosity of about 35 pb^-1. Using the decay lepton transverse momentum and
the missing transverse energy, the W decay angular distribution projected onto
the transverse plane is obtained and analysed in terms of helicity fractions
f0, fL and fR over two ranges of W transverse momentum (ptw): 35 < ptw < 50 GeV
and ptw > 50 GeV. Good agreement is found with theoretical predictions. For ptw
> 50 GeV, the values of f0 and fL-fR, averaged over charge and lepton flavour,
are measured to be : f0 = 0.127 +/- 0.030 +/- 0.108 and fL-fR = 0.252 +/- 0.017
+/- 0.030, where the first uncertainties are statistical, and the second
include all systematic effects.Comment: 19 pages plus author list (34 pages total), 9 figures, 11 tables,
