Pest control practices in the vegetable crops have been heavily dominated by the routine use of broad-spectrum insecticides to control pests. Concerns have emerged about the adverse consequences of over use of pesticide. These consequences include short and longterm health hazards, contamination and environmental degradation. To minimize the pest losses farmers heavily depend on the chemical pesticides and accessing pest management information from the pesticide dealers due to weak state extension support system.

To prepare the samples of different horizontal layers of bamboo, bottom portion of three year old bamboo was used. The epidermis of the strips was first removed with a fine blade. The epidermis was kept for chemical analysis and the rest of the strips were divided evenly based on volume into inner, middle and outer layers along the radial direction by a fine blade. The grinding process was the same as above described. All tests were conducted under the standards of American Society for Testing and Materials (ASTM) except for alcohol-toluene solubility of bamboo. There was...

For the six offices in our sample, Table 1 also shows the approximate density of computers by gross square feet as well as per employee. We do not have number of employees (or computer density per employee) for education and medical facilities. For high schools, where the number of students is known, equipment density per student could be a useful metric if we had surveyed the entire building, which we did not.

Before sending data across the network, Oracle Net buffers and encapsulates data into the session data unit (SDU). Oracle Net sends the data stored in this buffer when the buffer is full, flushed, or when database server tries to read data. When large amounts of data are being transmitted or when the message size is consistent, adjusting the size of the SDU buffers can improve performance, network utilization, or memory consumption. You can deploy SDU at the client, the application Web server, and the database server....

Competing geophysical/geochemical hypotheses for how Earth’s surface became oxygenated – organic carbon burial, hydrogen escape to space, and changes in the redox state of volcanic gases – are examined and a more biologically-based hypothesis is offered in response. It is argued that compared to the modern oxygenated world, organic carbon burial is of minor importance to the accumulation of oxygen in a mainly anoxic world where aerobic respiration is not globally significant. Thus, for the Paleoproterozoic Great Oxidation Event (GOE) ~ 2.

Another use of mobility comes about if the specific area of interest (within a larger area) is unknown during deployment. For example, if a network is deployed to monitor the migration of a herd of animals, the herd’s exact path through an area will be unknown beforehand. But as the herd moves, the sensors could converge on it to get the maximum amount of data. In addition, the sensors could move such that they also maintain complete coverage of their environment while reacting to the events in that environment.

A robust body of literature details reproductive effects in fish, amphibians, and reptiles related to exposure to endocrine disruptors. Evidence of these effects has also been seen in wild mammals such as polar bears and seals. Environmental exposure assessments and wildlife, laboratory and epidemiologic studies show exposure to low-level environmental contaminants, such as pesticides and other chemicals, subtly undermines the ability to reproduce.

Common household products –detergents, disinfectants, plastics, and pesticides– contain chemical ingredients that enter the body, disrupt hormones and cause adverse developmental, disease, and reproductive problems. Known as endocrine disruptors, these chemicals, which interact with the endocrine system, wreak havoc in humans and wildlife.

In this article we have introduced the concept of management control based on the need for all organisations to avail of the processes and mechanisms that enable them to create the most favourable conditions for these organisations to attain their objectives, while at the same time ensuring an effective and efficient use of their resources. The management control system seeks to orient in the decision-making process and influence the behaviour of the organisation members so that their performance increases its chances of achieving its objectives.

This meant that the plants were doing little in the beginning to clean the inflow. In the beginning it was not known if the plants would survive such a harsh environment. But after five months the plants have proven that they are a plant well designed for this environment. Some benefits about these plants are that they produce no seed, have no rhizomes, and can only reproduce by physically moving a piece of the plant. At five months, the plants are three feet in height and the root systems are now reaching the bottom of...

Questions have been raised about the social impact of widespread use of social networking sites (SNS) like Facebook, LinkedIn, MySpace, and Twitter. Do these technologies isolate people and truncate their relationships? Or are there benefits associated with being connected to others in this way? The Pew Research Center’s Internet & American Life Project decided to examine SNS in a survey that explored people’s overall social networks and how use of these technologies is related to trust, tolerance, social support, and community and political engagement.

Both human activities and natural activities can change the physical, chemical, and biological characteristics of water, and will have specific ramifications for human and ecosystem health. Water quality is affected by changes in nutrients, sedimentation, temperature, pH, heavy metals, non-metallic toxins, persistent organics and pesticides, and biological factors, among many other factors (Carr and Neary 2008). Following are brief discussions of these major contaminants.
