Bacillus thuringiensis can produce a floating biofilm which includes two parts: a ring and a pellicle. The ring is a thick structure which sticks to the culture container, while the pellicle extends over the whole liquid surface and joins the ring. We have followed over time, from 16 to 96 h, sporulation in the two biofilm parts. Sporulation was followed in situ in 48-wells polystyrene microtit...

This paper presents cell culture substrates in the form of microcontainer arrays with overlaid surface topographies, and a technology for their fabrication. The new fabrication technology is based on microscale thermoforming of thin polymer films whose surfaces are topographically prepatterned on a micro- or nanoscale. For microthermoforming, we apply a new process on the basis of temporary bac...

Abstract Metacognitive abilities are considered as a hallmark of advanced human cognition. Existing empirical studies have exclusively focused on populations from Western and industrialized societies. Little is known about young children’s metacognitive in other societal cultural contexts. Here we tested 4-year-old Yucatec Mayan (a rural native population Mexico) by adopting task which explicit...

This paper studies the incidence relation between the points and quadrics in the projective space of a symplectic vector space over a field of even order. The 2-rank of the incidence matrix is determined. This is achieved by viewing the code generated by incidence vectors as a module for the symplectic group and applying the 2-modular representation theory of this group. The radical series of t...

This paper addresses scheduling problems on the material handling operation at marine container-yard terminals. The layout, removal order and removal distination of containers are simultaneously optimized in order to reduce the waiting time for a vessel. The schedule of container-movements is derived by autonomous learning method based on a new learning model considering container-groups and co...

(The main idea: The compression used for stegotext detection. It is known that an embedding message breaks statistical structure of the container, increasing its entropy. Consequently, the full container will compress worse than empty. Let us consider the example: A, B empty and full container respectively. Table 1: Container size before and after compression container.. container size before c...

Abstract—Currently container terminals are busy to handle high volume of container shipping movement. Conventional operational procedures have difficulties in handling containers movement, thereby slowing clearances and even resulting in some administrative issues in terminal operation. This paper presents an development of Information and Communication Technology (ICT) in a container terminal...

It is important to secure food safety. If a packaged can be sterilized, poisoning reduced considerably because the in plastic container useful prevent attaching microorganisms. However, fresh food, e.g., salad or sashimi, cannot sterilized by thermal sterilization. Therefore, we are studying sterilization methods for foods, such as packed salads. In this study, have investigated applicable prob...
