Hermetic storage is used to protect grain against insect pests, but its utility is not limited to whole grains. We evaluated hermetically-sealed, polyethylene terephthalate (PET) bottles for preserving wheat and maize flour against red flour beetle (RFB, Tribolium castaneum, Herbst) population growth. Flours infested with RFB and kept in sealed PET bottles experienced much less weight loss over...

Language constructs for defining abstract types commonly come in two varieties: those that add and remove seals dynamically as values cross the abstraction boundary, and those that define the boundary statically using a type signature. Abstract types in dynamically-typed languages are generally defined using seals whereas statically-typed languages more typically use a signature; two prominent ...

With the discovery of many economic, environmental, and health problems in sealed and mechanically ventilated buildings, the concept of natural ventilation has been revived. "Buildings that breathe" have become more and more desired by ordinary people and architects. Although natural ventilation is conceptually simple, it is difficult to design and control. At present, methods to study natural ...

The precise number of sealed sources in use is unknown because many countries do not systematically account for them. However, nearly 10 million sealed sources exist in the United States and the 49 countries responding to a GAO survey. There is also limited information about the number of sealed sources that have been lost, stolen, or abandoned, but it is estimated to be in the thousands worldw...

Background: The chick embryo is a classical model to study embryonic development. However, most researchers have not studied the effect of embryonic manipulation on chick hatchability. To determine the effect of egg orientation and type of sealing film on the hatchability of cultured embryos, and to determine the fate of adulte stem cells injected into the blastoderm. Materials and Methods: Win...

objective: long-term retention of pit and fissure sealants is crucial for their success. this clinical study evaluated the retention rate of a flowable composite resin (filtek supreme xt flowable restorative) compared to a conventional resin-based sealant (concise light cure white sealant) over 12 months. materials and methods: forty subjects aged 6 to 9 years were included in the study. using ...
