Non coding endogenous RNAs were first discovered in the last decade of the previous
century. These new discoveries changed our views of the transcriptome landscape of
plant genomes and paradigms of the regulation of gene expression. With the beginning
of this century, we have witnessed an explosion of studies on small regulatory
RNAs that has yielded a basic understanding of the many types of small RNAs in
diverse eukaryotic species and how they are functioning as RNA–protein complexes
along the RNA silencing pathways.

It has been a privilege to watch the growth of RNA interference technology over
the last ten years. Starting with a mixture of curiosity and chagrin, the field has
grown into a substantial enterprise which impacts (and utilizes resources from)
virtually every field of biomedical research. Research in RNAi derives from a set of
apparently unconnected observations: strange pigment patterns in plants, unexpected
failures and successes in antisense and overexpression studies, small regulatory
RNAs in bacteria.
Epstein–Barr virus (EBV) is a potent mitogenic and anti-apoptotic agent for B lymphocytes and is associated with
several different types of human tumour. The abundantly
expressed small viral RNA, EBER-1, binds to the growth
inhibitory and pro-apoptotic protein kinase R (PKR) and
blocks activation of the latter by double-stranded RNA.
Recent evidence has suggested that expression of EBER-1
alone in EBV-negative B cells promotes a tumorigenic phe-notype and that this may be related to inhibition of the pro-apoptotic effects of PKR....
Hfq proteins are common in many species of enterobacteria, where they
participate in RNA folding and translational regulation through pairing of
small RNAs and messenger RNAs. Hfq proteins share the distinctive Sm
fold, and form ring-shaped structures similar to those of the Sm⁄Lsm pro-teins regulating mRNA turnover in eukaryotes.

Difficulty in addressing contamination in low permeability soils may be
alleviated to some degree by controlled pneumatic or hydraulic fracturing of the
soil. However, engineered hydraulic fractures generally cannot be spaced more
closely than about 5 feet, which means that chemical oxidants must still penetrate a
substantial thickness of low permeability soil to come into contact with the
contamination. Deep soil mixing with large diameter drill augers is the most
effective method currently available to increase contact between adsorbed
contaminants and the oxidants.
Carbon offsets are an innovative tool for allowing companies and individuals to reduce
greenhouse gas emissions beyond what they can easily achieve on their own. In the past
two years, interest in carbon offsets has grown dramatically as companies and concerned
consumers have sought ways to help mitigate climate change. However, the global
market for voluntary carbon offsets is currently unregulated, which has led to growing
concerns about whether buyers are really getting what they are paying for.
Lenne, 1996) and to decrease
damage by pests and pathogens (Cantelo & Sanford, 1984). In some crops (e.g. rice) this is
applied on a large scale to maximize yield by minimizing damage by pathogens (Zhu et al.,
2000). Information on genetic diversity and population structure also assists plant breeding
in the selection of parents for crossing, providing a more rational basis for expanding the
gene pool, and for identifying materials that harbor genes of value for plant improvement.
The annual agriculture appropriations bill traditionally makes two separate appropriations for the
federal crop insurance program. It provides discretionary funding for the salaries and expenses of
the RMA. It also provides “such sums as are necessary” for the Federal Crop Insurance Fund,
which finances all other expenses of the program, including premium subsidies, indemnity
payments, and reimbursements to the private insurance companies.
Government costs for crop insurance have increased substantially in recent years. After ranging
between $2.1 and $3.

In 1992, the first United Nations Conference on Sustainable
Development, popularly known as the Rio Earth Summit, was convened
in Rio de Janeiro, Brazil to address the state of the environment and
sustainable development. The Earth Summit yielded several important
agreements including “Agenda 21”, a plan of action adopted by over
178 governments to address human impacts on the environment at
local, national and global levels, and key treaties on climate change,
desertification and biodiversity.
Building engineering physics emerged during the latter part of the 20th
Century, at the interface between three disciplines: building services
engineering, applied physics and building construction engineering. Building
services engineering is the design of mechanical and electrical systems to
maintain internal environmental conditions that enable occupants to be
comfortable and achieve their maximum performance potential.
The treaty, called the Stockholm Convention on Persistent Organic Pollutants, is a
major achievement. It starts by immediately targeting 12 particularly toxic POPs for reduc-
tion and eventual elimination. More importantly, it sets up a system for tackling additional
chemicals identified as unacceptably hazardous. It recognizes that a special effort may
sometimes be needed to phase out certain chemicals for certain uses and seeks to ensure that
this effort is made. It also channels resources into cleaning up the existing stockpiles and
dumps of POPs that litter the world’s landscape.
