  • The same amount of water has been present on our planet for about 4 billion years, since shortly after the Earth was formed. Since then it has cycled through evaporation, condensation, precipitation and surface runoff multiple times. Water scarcity as an abiotic factor ranging from moderate to severe stress levels, accompanied by loss of moisture in the soil, is extremely hard for most organisms to cope with, particularly terrestrial plants and their food-chain dependents.

  • A global research community of scientists is teasing out the biochemical mechanisms that regulate normal cellular physiology in a variety of organisms. Much of current research aims to understand the network of molecular reactions that regulate cellular homeostasis, and to learn what allows cells to sense stress and activate appropriate biochemical responses.

  • The BAT (Best Available Techniques) Reference Document (BREF) entitled “Best Available Techniques for the Manufacture of Organic Fine Chemicals” (OFC) reflects an information exchange carried out under Article 16(2) of Council Directive 96/61/EC (IPPC Directive). This executive summary describes the main findings, a summary of the principal BAT conclusions and the associated consumption and emission levels. It should be read in conjunction with the preface, which explains this document’s objectives; how it is intended to be used and legal terms.

  • Controlled oxidation is increasingly being practiced using solid peroxides, pH modifiers, and catalysts that promote the generation of free radicals. This new approach moderates the rate of dissolution and peroxide generation, which in turn controls that rate of reaction between peroxide and the petroleum contaminants. The use of slurried peroxides creates the opportunity to release oxidants and oxygen over a longer period, which can promote subsequent aerobic remediation.

  • While it has been demonstrated that these materials have good sensitivity to polar VOCs, such as alcohols and acetone, 11,12 their rather poor response to nonpolar analytes has been viewed as a major drawback. In this report, we explored two ways to improve the sensor performance of regioregular polythiophene. The first approach is to add a second polymer at the end of the polythiophene chain to form a block copolymer. This second polymer interacts with the analytes in different ways, thus adding another dimensionality to the sensing response of the material.

  • This is a frightening development. There are traces within you – or, depending on your circumstances and exposures, more than traces – of several hundred man-made chemicals. Many are harmless (or at least are so far thought to be). Others, however, may cause cancer and damage the nervous systems, reproductive systems, immune systems, or livers of animals. Mounting scientific evidence is confirming long-term suspicions that they do the same to human beings.

  • Often destinations are artificially divided by geographical and political barriers, which fail to take into consideration consumer preferences or tourism industry functions. An example of that is the Alps shared by France, Austria, Switzerland, Italy by often perceived and consumed as part of the same product by skiers. For the purpose of this paper destinations are considered to be a defined geographical region which is understood by its visitors as a unique entity, with a political and legislative framework for tourism marketing and planning.

  • Emission profiles should be recorded instead of levels derived from short sampling periods. Emission data should be related to the operations responsible. For emissions to air, BAT is to monitor the emission profile which reflects the operational mode of the production process. In the case of a non-oxidative abatement/recovery system, BAT is to apply a continuous monitoring system (e.g. Flame Ionisation Detector, FID), where exhaust gases from various processes are treated in a central recovery/abatement system.

  • A common physiological response of organisms to environmental stresses is the increase in expression of heat shock proteins (Hsps). In insects, this process has been widely examined for heat stress, but the response to cold stress has been far less studied.

  • Immunization coverage has been regarded an one of the parameters for measuring the effe ctiveness of the health programme of organization to the plight of the displaced persons, particularly, children. It could be observed from the table (Table 2) that immunization coverage was substantial for meningitis (34.72%) followed by measles (20.65). Lafia town is naturally both humid and hot and so, the relatively high level of immunization with cerebrospinal meningitis antigen is a justifiable preventive action by the state government.

  • A food may test positive for glucose but not have enough glucose to taste sweet, or the sweet flavor may be masked, e.g. by a sour flavor. Sweet foods may have little glucose, but significant amounts of other sugars (or artificial sweeteners that bind to taste receptors for sugars). When there is a small amount of a type of molecule (e.g. fat in pretzels) the tests used in this activity may not be sensitive enough to read positive. The results of the protein test for pretzels may be somewhat ambiguous, but if a little bit of pretzel is crushed...

  • Design a plan to get the information you need to figure out who took Jerell's iPod by using the tests for different types of organic compounds. Advice: You will need to test the dry and liquid parts of Jerell's evidence separately since the tests for organic compounds will not work if you combine the dry and liquid parts of the evidence. To test the pretzel, crush a little bit into fine crumbs. To test the beans, mash them into a paste. Do not add water when you test the beans, yogurt or liquid part of Jerell's evidence. ...

  • Essentials of supply chain management is written especially for two groups of readers. It is written for the senior executive who must decide what kind of supply chain their organization needs and how much to spend to get it. It is also written for the manager who is or soon will be responsible for building and operating some part of his/her company’s supply chain. The concepts and techniques presented here serve to create a common frame of reference that both senior executives and line managers can use when communicating with each other about supply chain management issues.

  • In a 2004 survey of 200 IT professionals from 14 countries in the Americas, Asia/Pacific and Europe, the IT Governance Institute (ITGI) found that in 80% of organizations, IT management is solely responsible for defining and addressing IT risk impact. This widespread lack of involvement by business unit managers demon- strates a consistent—and alarming—gap in mapping technology risk to the business. Additionally, this gap als shows that most organizations have inadequate IT risk assessment processes across their enterprises.
