Mechanisms of salt tolerance in halophytes: can crop plants resistance to salinity be improved? High concentrations of sodium are toxic to most plant species, making soil salinity a major abiotic stress in plant productivity world wide. Many crop species, which countless people rely for survival, are negatively affected.
Objectives: Identifying the salinity tolerance and phenotype of the rice lines which carrying the Saltollocus (donor plant), imported from International Rice Research Institute, as well as selecting the popularly grown rice cultivar were used as the recipient plant Applying marker assisted backcrossing (MABC) to pyramid salinity tolerance Saltol locus into Bac Thom 7, in order to generate the high quality rice variety with salinity tolerance for growing the coastal areas in Red River Delta.
Salinity stress negatively impacts agricultural yield throughout the world affecting production whether it is for subsistence or
economic gain. The plant response to salinity consists of numerous processes that must function in coordination to alleviate both cellular
hyperosmolarity and ion disequilibrium. In addition, crop plants must be capable of satisfactory biomass production in a saline
environment (yield stability).

Glutaminase from Micrococcus luteusK-3 [Micrococcusglutaminase
(Mglu); 456 amino acid residues (aa); 48 kDa] is a salt-tolerant enzyme. Our
previous study determined the structure of its major 42-kDa fragment. Here,
using new crystallization conditions, we determined the structures of the
intact enzyme in the presence and absence of its product l-glutamate and its
activator Tris, which activates the enzyme by sixfold.
Populations in developing countries are growing so quickly that the land and
water are unable to sustain them. In most developing countries, prime farmland
and fresh water are already fully utilized. Although irrigation can be employed to
bring land in arid areas into production, it often leads to salinization. In some
countries, the amount of newly irrigated land is equalled by salinized irrigated
land going out of production. Moreover, irrigation water is often drawn from
river basins or aquifers shared by several countries, and friction over its use is
Abstract This study was conducted in order to evaluate the probiotic properties of lactic acid bacteria (LAB) isolated from intestinal tract of broilers and Thai indigenous chickens. The major properties, including the gastric juice and bile salts tolerance, starch, protein and lipid digesting capabilities, and the inhibition on certain pathogenic bacteria were investigated. Three-hundred and twenty-two and 226 LAB strains were isolated from ten broilers and eight Thai indigenous chickens, respectively....
Three major approaches can be used in an effort to segment a market.
the a-priori, a-posteriori and hybrid approach. The selection of an approach depends
on the objectives of the researcher in undertaking a segmentation study.
In a-priori (predetermined) market segmentation, the type (segmentation variables)
and number of market segments are determined before data collection. With this ap-
proach, there are two main questions, namely the estimated sizes of these segments in
the market place, and some relevant segment characteristics ( descriptor variables).
Lichens are long-lived and can be monitored, field conditions permitting, in any season. Many lichens
have extensive geographical ranges, allowing study of pollution gradients over large areas. These
properties make them useful for spatial and temporal evaluation of pollutant accumulation in the
environment. Epiphytic lichens (those that grow on trees or plants) are often best suited to the study of air
pollution effects on lichen communities, lichen growth or physiology, and to the study of pollutant loading

Phototrophy is the process by which organisms trap photons and store energy as chemical
energy in the form of adenosine triphosphate (ATP). ATP transports chemical energy within
cells for metabolism. There are three major types of phototrophy: Oxygenic and Anoxygenic
photosynthesis, and Rhodopsin-based phototrophy. Photosynthesis is a chemical process
that converts carbon dioxide into different organic compounds using solar energy. Oxygenic
and anoxygenic photosynthesis undergo different reactions in the presence and absence of
light (called light and dark reactions, respectively).
The Bank, IMF and World Bank participated in a Government Forum organized in March 2011 to discuss the recently approved Strategy for Arrears Clearance. A major conclusion from the workshop was the importance of reaching agreement on a Staff Monitored Program with the IMF as a critical component of the path towards arrears clearance and debt relief and a grandfathering of Zimbabwe by the IDA Executive Board if it is to benefit from the HIPC Initiative.
Often communities have to deal with local political considerations when they plan events.
No specific advice can be given to the promoter except to warn him or her that political
considerations are always important to the local community. Often a way to encourage
elected political officials to support an event is to show the monetary or quality-of-life
impact that a successful event would have on their communities or careers. Explaining the
positive impact encourages officials to support the public safety coordinators by providing
adequate local resources and funding.
Canadian GAAP requires the use of bid prices for
long positions and ask prices for short positions in
the fair valuation of investments traded in an active
market, rather than the use of closing prices currently
used for the purpose of determining Net Asset Value
(“NAV”). For investments that are not traded in an
active market, Canadian GAAP requires the use of
valuation techniques, incorporating factors that
market participants would consider in setting a price.
Genetic diversity is the fundamental source of biodiversity – the total number of genetic
characters contributing to variation within species. In other words it is the measure that
quantifies the variation found within a population of a given species. Genetic diversity
among individuals reflects the presence of different alleles in the gene pool, and hence
different genotypes within populations. Genetic diversity should be distinguished from
genetic variability, which describes the tendency of genetic traits found within populations
to vary (Laikre et al., 2009).
The Appendix consists of three tables. The first table lists the INNs of pharmaceutical
active ingredients that are eligible for duty-free treatment. The second table consists of
chemical prefixes and suffixes that may be combined with the INNs to specify
pharmaceutical derivatives that are also included in the agreement. The third table
specifies the chemical intermediates for which duties have been eliminated.
U.S. imports of products included in the Pharmaceutical Appendix totaled over $85
billion in 2009; U.S. exports of these products exceeded $41 billion.

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.
This trend reflects the ongoing disen-
chantment with mass media advertising based on the
difficulty of measuring its effectiveness. However,
the trend also reflects a desire by manufacturers and
retailers to get closer to customers in some form of
relationship marketing. A number of explanations
have been forwarded for the increasing popularity of
promotions (Dickson and Sawyer, 1990; Quelch,
1983; Low and Jakki, 2000; Dawes, 2004). One of
the key factors is the changing relationship with
