Investigating The Possibility Of Utilization Of Kaolin And The Potential Of Metakaolin To Produce Green Cement For Construction Purposes -A Review

Abstract: Geopolymers are inorganic alkali aluminosilicate gels, formed from reaction of mineral clays or aluminosilicate-bearing industrial wastes, and treated with alkali silicate solution at 40 -80°C. Geopolymers have been studied for several decades due to their excellent mechanical properties. They are suitable for use in construction and refractory applications. This paper summarizes some important research findings over the last 30 years and attempts to explain the chemistry and reaction mechanisms of the geopolymerisation process. Moreover, the paper emphasizes the potential to produce green cement powder from kaolin and metakaolin as an alternative to ordinary Portland cement (OPC)

Can, Want and Try: Parents' Viewpoints Regarding the Participation of Their Child with an Acquired Brain Injury

BACKGROUND: Acquired brain injury (ABI) is a leading cause of permanent disability, currently affecting 20,000 Australian children. Community participation is essential for childhood development and enjoyment, yet children with ABI can often experience barriers to participation. The factors which act as barriers and facilitators to community participation for children with an ABI are not well understood. AIM: To identify the viewpoints of parents of children with an ABI, regarding the barriers and facilitators most pertinent to community participation for their child. METHODS: Using Q-method, 41 parents of children with moderate/severe ABI sorted 37 statements regarding barriers and facilitators to community participation. Factor analysis identified three viewpoints. RESULTS: This study identified three distinct viewpoints, with the perceived ability to participate decreasing with a stepwise trend from parents who felt their child and family "can" participate in viewpoint one, to "want" in viewpoint two and "try" in viewpoint three. CONCLUSIONS: Findings indicated good participation outcomes for most children and families, however some families who were motivated to participate experienced significant barriers. The most significant facilitators included child motivation, supportive relationships from immediate family and friends, and supportive community attitudes. The lack of supportive relationships and attitudes was perceived as a fundamental barrier to community participation. SIGNIFICANCE: This research begins to address the paucity of information regarding those factors that impact upon the participation of children with an ABI in Australia. Findings have implications for therapists, service providers and community organisations

Parents' actions, challenges, and needs while enabling participation of children with a physical disability: a scoping review

Contains fulltext : 108967.pdf (publisher's version ) (Open Access)ABSTRACT: BACKGROUND: Pediatric rehabilitation considers Family-centered service (FCS) as a way to increase participation of children with a physical disability in daily life. An important principal is that parents greatly contribute to their child's participation at school, at home, and in the community. However, it is unclear what kind of information is available from literature about what parents actually do to support their child's participation and what problems and needs they experience? Hence, the aim of this study was to provide an overview of the actions, challenges, and needs of parents in enabling participation of their child with a physical disability that is neurological and non-progressive in nature. METHODS: Scoping review with extensive literature search (September 2011) and a thematic analysis to synthesize findings. RESULTS: Fourteen relevant articles revealed two major themes: 'parents enable and support performance of meaningful activities' and 'parents enable, change and use the environment'. Each theme holds a number of actions (e.g. choosing the right type of meaningful activities for facilitating social contacts) and challenges (e.g. negative attitudes of other people). Less information is available about the needs of parents. CONCLUSIONS: This study indicates that parents apply a broad range of strategies to support participation of their children. They experience many challenges, especially as a result of constraints in the social and physical environments. However, this review also shows that little is known about needs of parents in facilitating participation. As Family-centered service (FCS) philosophy is all about the needs of the child and the family, it is essential to further investigate the needs of the parents and to understand if and to what extent they wish to be supported in enabling their child's participation in daily life

Laparoscopic Rectopexy for Rectal Prolapse: Will it be the Gold Standard?

A review of the current literature is presented regarding the surgical management of full thickness rectal prolapse, comparing laparoscopic rectopexy with open abdominal operations and perineal procedures. Outcome measures include length of stay, short- and long-term outcomes and financial burdens. Current evidence suggests that laparoscopic rectopexy as treatment for full thickness rectal prolapse is a safe alternative to the other options
