Nanoscale manufacturing has enabled the development of smart packaging systems for the functional and convenient distribution of food products, overcoming the major bottlenecks to the future fabrication of stable, safe, economically feasible, and environmentally friendly food packaging systems. For example, nanotechnology can provide more functions of packaging systems to maintain, preserve, and sustain food products. In this work, we proposed a national design of biodegradable packaging nanoporous films (PNFs) to improve food quality preservation using polycaprolactone (PCL), biodegradable polymer, in combination with the nanofabrication technique. As a model study, we stored tomatoes with PCL PNFs in room and refrigerated temperature, respectively. Compared to conventional packaging films (i.e., polystyrene films), the PCL PNFs could retain the intact appearances of tomatoes. We also showed the higher mechanical property of tomatoes stored with the PCL PNFs than that of tomatoes with conventional packaging films, suggesting that the PCL PNFs could maintain food quality owing to probably the unique nanopore properties. We believe that biodegradable nanoporous films may be used as a new strategy to design smart food packaging systems for improving food quality preservation.
Multi-Level modeling and access control for data sharing in collaborative design
Kim, Taeseong,Cera, Christopher D.,Regli, William C.,Choo, Hyunseung,Han, JungHyun Elsevier 2006 ADVANCED ENGINEERING INFORMATICS Vol.20 No.1
<P><B>Abstract</B></P><P>This paper presents a method for securing collaborative design using multi-level modeling. When a team of designers works collaboratively on a 3D assembly model, a component of the assembly is presented in a full detail to those who have full access privileges to the component, but in an abstract level of detail to those who have less access privileges. Such various levels of detail can be created in two phases: volumetric feature removal which is achieved through interactive feature recognition on the CAD model, and multi-resolution mesh construction which is based on polygonal simplification. Appropriate representations of the assembly are extracted by direction of access matrix, and then presented to the users participating in collaborative design. The key issues in developing the secure collaborative design system are discussed, and the implementation results are reported.</P>

Nanotechnology has facilitated the development of active food packaging systems with functions that could not be achieved by their traditional counterparts. Such smart and active systems can improve the shelf life of perishable products and overcome major bottlenecks associated with the fabrication of safe and environmentally friendly food packaging systems. Herein, we used a plasma-enabled surface modification strategy to fabricate biodegradable and flexible nanoporous polycaprolactone-based (FNP) films for food packaging systems. Their capacity for preserving tomatoes, tangerines, and bananas at room and refrigeration temperatures was tested by analyzing various fruit parameters (mold generation, appearance changes, freshness, weight loss, firmness, and total soluble solids contents). Compared with commonly used polyethylene terephthalate-based containers, the proposed system enhanced the fruit storage quality (i.e., retained appearance, reduced weight loss, better firmness, and sugar contents) by controlling moisture evaporation and inhibiting mold generation. Thus, the FNP film represents a new active food packaging strategy.

Metastatic intestinal adenocarcinoma with osseous metaplasia in two Domestic Korean Shorthair cats

Two Domestic Korean Shorthair cats presented with dyschezia and vomiting. Computed tomography revealed a colonic mass with calcification and lymph node metastasis in case 1, and a small intestinal mass with disseminated mesenteric metastasis and calcification in case 2. Histopathology revealed intestinal adenocarcinoma with osseous metaplasia. Case 1 died two months after surgery from distant metastasis; and case 2 showed no metastasis for five months but presented with anorexia, euthanized seven months after diagnosis. Metastatic intestinal adenocarcinoma with bone formation should be considered as differential diagnosis for calcification on imaging, and lymph node metastasis at diagnosis may indicate poor prognosis.
