Phytochemical analysis of the leaves of Aglaia gigantea, Aglaia dasyclada and Aglaia oligophylla collected in Vietnam yielded three terpenoids, which included two triterpene Foveolin B (1), Niloticin (2) and one tetraterpene Lutein (3). The structures of these compounds were elucidated through extensive 1D and 2D NMR spectroscopy and analysis of their mass spectrometric data.

Periodontitis is one of the most common oral diseases and is characterised by gingival
inflammation and alveolar bone resorption (Savage et al. 2009). Periodontitis is a
multifactorial irreversible and cumulative condition, initiated and propagated by bacteria
and host factors (Kinane 2001). More than 500 different bacterial species are able to colonise
the oral biofilm and up to 150 different species of bacteria are possible in any individual’s

The pH values will bring effects in flora and
fauna nearby, change the taste of water and lead to heavy corrosion in pipe lines. High
conductivity naturally indicates the presence of ionic substances dissolved in the river
water. However, the result showed that 90% of the study site exceeded the data reported for
non-contaminated rivers due to excessive metal ions within the water. At the site nearer to
kaolin industry the conductivity is 852 times higher than the non-polluted study site. The
industrial discharge also changed the hardness in river water.

This category features the broadest application of the use of credit ratings. Member
authorities from every jurisdiction submitting responses indicated that their LRSPs contained
provisions using credit ratings for the purpose of determining net or regulatory capital, and
more LRSPs are applied to capital requirements than to any other category of use. Credit
ratings were generally used in those LRSPs as a means of mapping credit risks to capital
charges or risk weights.
A truly distributed service would allow a client to use services by connecting to a broker
nearest to the client’s geographical location. By having such local broker, a client does not
have to re-connect all the way back to the broker that it was last attached to. If the client is
not satisﬁed with the response times that it experiences or if the broker that it has connected
to fails, the client could very well choose to connect to some other local broker.
The Agency’s FY 2013 budget request supports the Administration’s commitment to ensure that
all Americans are protected from significant risks to human health and protect the environment
where they live, learn and work. The EPA’s work touches on the lives of every single American,
every single day as we protect the environment for our children, but also for our children’s
children. The mission, day in and day out, is to protect the health of the American people by
keeping pollution out of the air we breathe, toxins out of the water we drink and swim in, and
The dehesa is both a resilient and a fragile system; its resilience derives from the
perseverance of its operators, and its fragility is its susceptibility to unfavourable economic
factors that influence its profitability (Siebold, 2009).
Livestock grazing is an integral management component of a dehesa and undergirds the
conservation function of the system. The livestock component, including cattle, accounts for
the largest fraction of revenue from the dehesa.
Earlier in the year, when the affiliate rule was first implemented, the state expected that
the planned expansion of Medicaid to non-elderly adults with incomes under 133% of poverty
under the Affordable Care Act in 2014 would ensure that most of the low-income WHP clients
would become eligible for Medicaid and that additional support might only be needed for those
women with incomes between 138% and 185% of poverty.
Currently there is uncertainty about the degree of difference in nutrient composition
between conventionally and organically produced foodstuffs. Organic foodstuffs are those
that are produced according to specified standards which, among other things, control the
use of chemicals and medicines in crop and animal production, and emphasise protection
of the environment. Recently published non-systematic reviews comparing nutrient
composition of organically and conventionally produced foods have come to contrasting
Given the considerable variation in deposit insurance arrangements and the relatively
large number of banking crises, it is possible to use this panel to test whether the nature of the
deposit insurance system has a significant impact on the probability of a banking crisis once
other factors are controlled for. We carry out these tests using the multivariate logit econometric
model developed in our previous work on the determinants of banking crises (Demirg†e-Kunt
and Detragiache, 1998).
It has been a decade since book-length writing about law and the Internet began
in earnest. Ethan Katsh’s wonderful book Law in a Digital World (1995) is
just over a decade old, and anticipated the flood. My first book, Code and Other
Laws of Cyberspace (1999), is just under.
Most of these early books had a common character. We were all trying first to
make the obscure understandable, and second, to draw lessons from the understood
about how law and technology needed to interact.
In this paper we show that nontraded goods (in ¯nal consumption and in retail services)
play an important role in exchange rate behavior in the context of an otherwise standard
open-economy macro model. In our model, nontraded goods have an important role even
though °uctuations in the relative price of nontraded goods account for a small proportion
of real exchange rate °uctuations.
Our quantitative study with nontraded goods generates
implications along several dimensions that are more closely in line with the data relative to
the model that abstracts from nontraded goods.
Lipases (triacylglycerol acylhydrolases, E.C. 126.96.36.199) are ubiquitous enzymes of consid-
erable physiological significance and industrial potential. Lipases catalyze the hydrolysis of
triacylglycerols to glycerol and free fatty acids. In contrast to esterases, lipases are activated
only when adsorbed to an oil–water interface (Martinelle et al., 1995) and do not hydrolyze
dissolved substrates in the bulk fluid. A true lipase will split emulsified esters of glycerine
and long-chain fatty acids such as triolein and tripalmitin. Lipases are serine hydrolases.
