Phototrophic green bacteria, phototrophic purple
bacteria, and heliobacteria are three groups of bacteria that use anoxygenic photosynthesis.
Anoxygenic phototrophs have photosynthetic pigments called bacteriochlorophylls.
Bacteriochlorophyll a and b have maxima wavelength absorption at 775 nm and 790 nm,
respectively in ether. Unlike oxygenic phototrophs, anoxygenic photosynthesis only
functions using a single photosystem. This restricts them to cyclic electron flow only, and
they are therefore unable to produce O2 from the oxidization of H2O.
Because the scope of modern medical knowledge is vast, medical school
graduates undergo additional training before entering clinical practice. Those
choosing to become specialists take at least three years of residency training.
The American Board of Medical Specialties establishes criteria for its
member organizations, such as the American Board of Obstetrics and
Gynecology (ABOG). In turn, ABOG sets high standards for training and
performance for those physicians who wish to work in this specialty....
The success of the implementation of a New Policy Proposal will be judged in terms of the benefits delivered –
i.e. the measurable improvements resulting from outcomes which are perceived as an advantage by
From the moment the first elements of change are introduced into the operations of a department or agency
and on-the-ground in the public arena, expectations will be met or not met.
The RRL Pakchong was first established in 1958, and has since served as the National FMD
Laboratory in Thailand. Upon the recommendation of the OIE Sub-Commission for FMD
Control in South East Asia to develop the Laboratory into the SEAFMD Regional Reference
Laboratory, the DLD refurbished laboratory capacity by constructing a BSL-3 Containment
Laboratory. The BSL-3 has been designated as the SEAFMD RRL and has received samples
from South East Asian countries.
The absence of coordinated systems for data collection and record-keeping and the
maintenance of databases for the livestock sector, including a mechanism for feedback and
exchange among the stakeholders for development of livestock-related policies have been
identified as a major constraint for many countries in SAP. Such data recording, even on a
limited scale, is critical for genetic improvement of livestock.
Many developing countries are currently in the process of restructuring their economies towards
a more market-oriented production. This process had been initiated inter alia by efforts under
the auspices of the World Trade Organization (WTO) to progressively liberalize international
markets. More than 100 developing countries are now Members of the WTO. Since its
establishment in early 1995, it became evident that progressively subjecting national production
to market forces can have both positive and negative effects on Members’ economies, societies
Amongst the arguments raised against cloning has been
concern that reproductive cloning would lessen the respect
for individuals because of the feeling that they could
easily be replaced.
Every form of reproductive technology
raises some question of human values, dignity, worth and
juridical rights, some linked to the notion that the person
should not be used as a mere mechanical instrument, and
that every human individual is a non-repeatable being.
Nevertheless, it also seems likely that substantial demand for voluntary GHG
emission reductions can exist even where there are regulatory requirements. “Carbon
neutrality” has become a goal for many companies seeking to attract customers by
providing environmentally friendly products and services. Likewise, growing awareness
about climate change has sparked an interest among many individuals to do their part to
help solve the problem.
They were, one and all, from the broadest and best to the narrowest and least frequented, very
dark. The oil and cotton lamps, though regularly trimmed twice or thrice in the long winter
nights, burnt feebly at the best; and at a late hour, when they were unassisted by the lamps and
candles in the shops, cast but a narrow track of doubtful light upon the footway, leaving the
projecting doors and house-fronts in the deepest gloom. Many of the courts and lanes were
left in total darkness; those of the meaner sort, where one glimmering light twinkled for a...
This paper measures the role of quality-adjusted years of schooling in accounting
for cross-country output per worker differences. While data on years of schooling are
readily available, data on education quality are not. I use the returns to schooling
of foreign-educated immigrants in the United States to infer the education quality
of their birth country. Immigrants from developed countries earn higher returns
than do immigrants from developing countries; I provide evidence that this pattern
is likely explained by education quality differences and not selection.

Studies have found a few exceptions: changes to estate, inheritance and gift taxes have a small effect on the number of tax
returns filed in that state, although some of that decline may be due to households filing from a state where they have a
A study of New Jersey’s half-millionaire’s tax suggested that households with incomes over $500,000 were no more likely
to leave New Jersey after the higher rate was adopted. The only groups with an identifiable response were rich households
with heads age 65 and older and ‘super-rich’ households (in the top 0.
Current ‘envelope’ authorisations will be re-examined to ensure that they are still appropriate and represent
BAT. In practice the plant may be over-designed for many of the reactions so that it accommodates the full
range of operational conditions. The extra cost of this being offset against the commercial advantage the
operator may secure through increased flexibility. If plant usage evolves into a single product then it must be
optimised to ensure that it uses BAT to produce that product.
Likewise, there are some significant variances in contractors’ expectations for
growth in various market segments this year. For example, contractors in the
Southwest and Northwest are more optimistic about the outlook for highway
construction this year, with 32 percent of contractors expecting the market to increase in
the Southwest, versus 31 percent expecting a decrease while 31 percent of contractors
in the Northeast expect an increase and 30 percent a decrease, for a net positive of 1
percent for each region.
Almost all businesses start small. The U.S. Census Bureau’s Statistics of U.S. Businesses (SUSB)
shows that over the last 20 years, about 95 percent of new employer firms started with fewer than
20 employees. Along with start-ups come closures. Firms with fewer than 20 employees also
account for 95 percent of closures. This illustrates that business turnover is the domain of small
Establishment turnover follows similar patterns.
This report presents evidence of the growing use of laptop computers. Because of their inherent portability,
accounting for laptops is difficult, especially during an after-hours survey, but our conservative estimate is
that laptops comprise at least 10% of the non-server computers in our sample. We also estimate that
laptops outnumbered desktop computers at two sites: one medium and one large office. To the extent that
relatively energy-efficient laptops are replacing desktop computers, significant electrical energy is saved.
However, more work is...
Moreover, strategies that account for predictable active management skills
tilt more heavily toward mutual funds that overweight technology and energy stocks
during recessions, and ﬁnancial and metals stocks during expansions, indicating that
business cycle variables are key to timing these industries. Remarkably, predictable skill
strategies also choose individual mutual funds within the outperforming industries that, in
turn, substantially outperform their industry benchmarks, even though these industry
benchmarks do not account for any trading costs or fees.
Life skills are abilities for adaptive and positive behaviour that enable individuals to
deal effectively with the demands and challenges of everyday life (WHO definition). In
particular, life skills are psychosocial competencies and interpersonal skills that help
people make informed decisions, solve problems, think critically and creatively,
communicate effectively, build healthy relationships, empathise with others, and cope
with managing their lives in a healthy and productive manner.
Mortality from breast cancer is falling in all age groups; in 1999, case-
fatality rates were about one-fifth lower than in the mid-1980s. The
reasons for this are not certain, but earlier diagnosis through
screening and improvements in treatment, particularly greater use of
adjuvant therapies, undoubtedly contribute.
Five-year survival rates are highest among people aged 50-59 at
diagnosis; both younger and older patients have a lower survival rate
In coordination with the MNCH component of the GHI strategy, prevention of NTDs will also
include the promotion of WASH practices in households, the provision of safe water and
construction of sanitation facilities. Since lymphatic filariasis (LF) can be prevented through the
use of bednets, efforts in this arena can be more tightly integrated with PMI to emphasize bednet
distribution in areas with LF, even if malaria is not highly prevalent.
