An overview of out-of-step protection in power systems

Power system is subjected to an extensive variety of little or bigger disturbance to the system during the operation. The power system that designed as one of the main requirement is to survive from the larger type of disturbances like faults. The power swing in certain system is the variation in three phase power flow in the power system. This paper mainly discussed the power swing and distance relay and the effect of the power swing on the distance relay and demonstrate about the basic power system stability and power swing phenomena. Moreover, out of step protection and detection applications are revised as well. At the end, the paper also demonstrated the past study of out of step application of TNB 275 KV network

Shaah & Sheeko : Embracing Identity in the Multisensory Space for Adolescent Girls

The purpose of this thesis is emphasising the act of embracing identity of the multi- and bi-cultural adolescents in a Multisensory environment. Another aim for this thesis is for the adolescents to communicate constructively. These objectives conclude towards the aim of improving self-reflection skills of the participants. The thesis is in partnership with ELO-project (“Building skills and Communities Together”). Multisensory Space is located in Laurea University of Applied Sciences Tikkurila Campus, in Vantaa. We observed the level of self-reflection skills of the participants as well as communication skills, and their self-expression skills. This was achieved through assembling a group for adolescent girls with immigrant background. We held 6 sessions with different themes: Introduction to the project and the Multisensory Space, Art Activities, Building the Multisensory Space, Constructive Communication, Tradition, Love and Relationships, and lastly Past, Present and Future. Each theme was based on the theoretical framework, of which the most important ones include: art therapy, Nonviolent Communication, Life Span Narrative. Our group started to resonate with the concept of Multisensory Space once they understood its function, even though in the beginning they were hesitant and had hard time comprehending how this space could work. One of our most favoured sessions was the Art Activity, which worked as a great tool for using creativity in expressing identity. The participants were able to express themselves and through that, caused interaction that ended up encouraging inclusion within the group. One of the observations we had made, was how easily the girls were able to create a space that resonated with their personal identity, by forming the Multisensory Space into Finnish and Somali. We used our observations and the received verbal and written feedback to conclude, that bi-cultural adolescents do not have enough safe and comfortable environments, where they can express themselves, and reflect on their identity. The participants were also able to use their artistic creativity to explore their opinions towards Finland and Somalia. They also explored their emotional connection towards their Somali identity and contemplated how it corresponds with their Finnish identity

Somali Business Review 2015

The businesses are changing and growing faster, there are a lot of people who are coming back to the country to start out their businesses, a lot of businesses were started in different sectors, and markets are looking to be busy for serving the customers. Even though the unemployment of the country is high, as there are a lot of unemployed individuals, Some organizations are helping out the youth to start and operate their businesses to fight with the unemployment by providing training and grants these caused a lot of youth to improve their livelihoods and get a source of income. Given that Somalia has been at war from the early nineties, the water division infrastructure is broken down and will have to be rebuilt and reformed to serve the people of Somalia. There are opportunities in the supplying water sector materials range from small hand well digging to complex drilling borehole of services, to take advantage from the opportunities in the market for the water sector materials, it’s good to get the stocks needed for the water supply. In this issue covers articles that address business opportunities focusing on some sectors of the market and the new technologies used for the businesses to enhance their recording. Islam is a religion presenting a system for the welfare of the society and prohibits a system where people earn income without putting work or efforts so we provided an article about the Wisdom Behind Elimination of Riba in Financial transactions

SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study

Background: Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods: The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results: NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion: As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population
