The COCOON project was intended to extend the concepts and the architecture of relational database management systems (DBMSs) beyond nested relational to object-oriented ones. Based upon the nested relational DBMS kernel DASDBS, we have built a prototype implementation of the COCOON model. Key characteristics of COCOON are: generic, set-oriented query and update operators similar to relational ...

Growth (length, biomass and mean growth rate) and reproduction (total duration, clitellum appearance, clitellum completion, cocoon commencement, rate of cocoon production, incubation period, hatching success and mean number of hatching per cocoon) of indigenous Lampito mauritii (Kinberg) in comparison with exotic Eudrilus eugeniae (Kinberg) cultured on three feed substrates-clay loam soil, cowd...

Abdominal cocoon or sclerosing encapsulating peritonitis (SEP) is a rare cause of intestinal obstruction described mostly in young adolescent girls. Thick fibrotic peritoneum encasing the small bowel is a pathognomonic feature. Preoperative diagnosis is rare. A 37-year-old man with hypertension and chronic renal failure presented with complaints of vomiting and abdominal pain lasting a few days...

Efficacy of radiotherapy treatment depends on the specific characteristics of tumorous tissues. For the determination of these characteristics, clinical practice uses Dynamic Contrast Enhanced (DCE) Magnetic Resonance Imaging (MRI). DCE-MRI data is acquired and modeled using pharmacokinetic modeling, to derive per voxel a set of parameters, indicative of tissue properties. Different pharmacokin...

According to the collapsar model, γ-ray bursts are thought to be produced in shocks that occur after the relativistic jet has broken free from the stellar envelope. If the mass density of the collimated outflow is less than that of the stellar envelope, the jet will then be surrounded by a cocoon of relativistic plasma. This material would itself be able to escape along the direction of least r...

In this work, we synthesized graphene oxide from silk cocoon embarking its new dimension as a magnetic fluorophore when compared with its present technical status, which at best is for extracting silk as a biomaterial for tissue engineering applications. We produced graphene oxide by pyrolysing the silk cocoon in an inert atmosphere. The collected raw carbon is oxidized by nitric acid that read...

The aim of the COCOON project is to investi gate the design of an object oriented data model with main emphasis on e cient implementation of queries and updates While the nested rela tional kernel of DASDBS is the target physical storage system for COCOON the model is also implemented on top of commercial database sys tems as rst prototypes and to analyze feasibility and compare performance Thi...

Three biomarkers in Aporrectodea caliginosa Savigny were evaluated for their ability to detect exposure to organophosphorus insecticides, and these physiological responses were related to effects on growth and life-table parameters. Adult and juvenile earthworms were exposed to a laboratory-simulated field rate (low concentration) and a higher sublethal concentration of diazinon and chlorpyrifo...

Cocoon is defined as a strategy to reduce the risk for transmission of pertussis to newborn infants by vaccinating household members including parents and siblings. Programmatic challenges make implementation of cocooning program complex. At the local health care unit "ASL Napoli 1 Centro," a one-year pilot project to evaluate the newborn contacts adherence to a cocoon strategy was started on M...
