Security: hash function-authentications

As security or firewall administrator, we got basically the same concerns (as a plumber) the size of the pipe the contents of the pipe, making sure the correct traffic is in the correct pipes and keeping the pipes from splitting and leaking all over the places of course like plumbers. When the pipes do leak: we are the ones responsible for cleaning up the mess and we are the ones who come up smelling awful. Firewall is a device that is used to provide protection to a system from network-based security threats. The firewall uses service, behavior, user and direction control techniques

Spreading awareness and job opportunities through odl

Distance Education has done miracles in the field of education, it caters to those students who study and work on their own at home or at the office and communicate with faculty and other students via e-mail, electronic forums, video conferencing, chat rooms, boards, instant messaging and varieties of other forms of computer-based communication. Distance learning makes it much easier for some students to complete a degree or get additional job-training while balancing work and family commitments. This article elaborates upon the significance of Distance Education discussing various job oriented courses offered by Open universities to aspirants seeking degrees for a better resume and for career enhancements

The impact of economic crisis on tourism industry: Bangladesh perspective

The tourism sector is experiencing numerous challenges as a result of the global economic crisis. After a significant contraction in 2009, tourism rebounded strongly in 2010 and in 2011 the international tourist arrivals and receipts are projected to increase substantially. The Tourism industry is expected to show a sustained recovery in 2012. The crisis has a particularly strong impact and slightly negative consequences in Bangladesh. The country is undergoing a political crisis, as well, and it seems that the forthcoming elections may be the only solution for the restoration of stability and social peace.  In addition, tourism can be the driving force behind Bangladesh economic recovery. However, for its achievement, the country’s policymakers should take several measures towards restructuring and improve the sector. These measures include enhancement of alternative forms of tourism; environmental protection; creation of quality infrastructure; and a boost of competitiveness through a tourism product that offers value for money

Performance, modeling, measurements, and simulation of energy efficient for heat exchanger, refrigeration and air conditioning

Over the years, all parts of a commercial refrigerator, such as the compressor, heat exchangers, refrigerant, and packaging, have been improved considerably due to the extensive research and development efforts carried out by academia and industry. However, the achieved and anticipated improvement in conventional refrigeration technology are incremental since this technology is already nearing its fundamentals limit of energy efficiency is described is ‘magnetic refrigeration’ which is an evolving cooling technology. The word ‘green’ designates more than a color. It is a way of life, one that is becoming more and more common throughout the world. An interesting topic on ‘sustainable technologies for a greener world’ details about what each technology is and how it achieves green goals. Recently, conventional chillers using absorption technology consume energy for hot water generator but absorption chillers carry no energy saving. With the aim of providing a single point solution for this dual-purpose application, a product is launched but can provide simultaneous chilling and heating using its vapor absorption technology with 40% saving in heating energy. Using energy efficiency and managing customer energy use has become an integral and valuable exercise. The reason for this is green technology helps to sustain life on earth. This not only applies to humans but to plants, animals and the rest of the ecosystem. Energy prices and consumption will always be on an upward trajectory. In fact, energy costs have steadily risen over last decade and are expected to carry on doing so as consumption grows

A society based research to assess adherence of antiretroviral therapy

Access Adherence to Antiretroviral Therapy. A community-based antiretroviral (ART) drugs adherence study was conducted in Kolkata, India beginning in January and concluding in March 2011. This study was designed to explore the level of adherence as well as factors influencing adherence to ART by those who are receiving treatment through a public health care delivery system. This health care system is implemented through the National AIDS Control Program in the state of West Bengal, India. The research findings showed a high degree of non-adherence, between 48-52%, among the ART recipients. The analysis highlights a number of key factors negatively influencing adherence including long waiting time at the ART center, distance from residence to ART Centre, travel related expenditure, and fear of being identified as HIV + to family members and neighbors. Some positive influences were identified in the data as well. If a person is a member of a positive people network there is a greater chance for adherence as well as if an individual self-identifies as positive to others. However, no single factor, rather a combination of several factors, proved to be responsible for influencing ART adherence among recipients. &nbsp
