Identification of maintainer and restorers from rice germplasm through test crossing is the initial step in three line heterosis breeding. Maintainer lines can be converted into cytoplasmic male sterile lines to utilize in development of rice hybrids. Restorer lines can be used as males to produce F1 hybrids. Three hundred F2 plants of the cross KCMS 26A X IET 19886 were grown under aerobic sit...

Through soft modeling of data collected from a survey of 83 Information Systems (IS) organizations in Singapore, this paper develops and tests a Partial Least Square (PLS) model that determines the impact of user knowledge, application quality, and maintenance control procedures on maintainer effectiveness. It was found that application quality has a very strong influence on maintainer effectiv...

An experiment was conducted at Bangladesh Rice Research Institute (BRRI), Gazipur during T.Aman season of 2007 with a view to evaluating seven maintainer and 30 restorer lines for yield and yield contributing characters for selecting promising maintainer and restorer lines for developing rice hybrids in our local environment. Significant variations were noticed among the parental lines for all ...

Traumatic injuries to primary teeth are very common. A properly designed fixed space maintainer not only preserves arch length but also reduces the psychological trauma, speech problems and prevents the development of tongue thrusting habits. As, it is difficult while operating in such young patient’s mouth, this article describes a simple technique to quickly fabricate a space maintainer for a...

INTRODUCTION The early loss of deciduous molars is a frequently encountered problem in dentistry. Various space maintainer designs were developed to prevent the loss of the space. The aim of this study was to evaluate long-term clinical performance and survival rates of fiber-reinforced composite resin (FRCR) as a space maintainer clinically. MATERIALS AND METHODS This study was designed on 4...

Premature loss of a primary tooth is one of the most common etiology for malocclusion. Space maintainers are employed to prevent this complication. In anterior region, esthetics is an important concern along with function and space management. Fiber-reinforced composite (FRC) retained space maintainer solves all these purposes ef ficiently and ef fectively. In addition, the technique is simple ...
