In order to reduce a microbial contamination and needle stick injuries that are associated with a mixing procedure in home parentera nutrition(HPN), nutrition(TPN)solution bags pre-mixed with trace elements may be provided in a form of outer packaging. On the other hand, a packaging form used to enclose the TPN bag after admixture may significantly affect the stability of vitamins. With a focus on possible decrease in vitamin B1 and C content, we investigated the effects of the packaging form. As a result, the TPN bag, which is packed in a light-resistant outer wrap of oxygen-barrier film with an oxygen absorbent under reduced pressure, suppressed a decrease in vitamin content most. However, the decrease in vitamin C content was observed when there was a long time-lag between a preparation and a packaging. We thought it was desirable to pack the TPN bag promptly after the preparation.

    We propose a modeling framework for Multivariate marginal models which provides flexible model building strategies. We show that the model handles several response families such as binomial, Count and continuous. We illustrate the model on Mother's Stress and Children's Morbidity data set. A simulat...

    Our results agree with the previous theoretical predictions well. It is found that the polymer reduces the line tension of membrane edges, as well as the interfacial line tension between membrane domains, leading to microdomain formation. Instead of the mixing of two phases as seen in typical binary...

    We study in details The dynamics of inner core thermal convection when dynamically induced melting And freezing of the inner core boundary (ICB) are taken into account. If the Inner core is unstably stratified, linear stability analysis and numerical Simulations consistently show that the translatio...
