Since long before the use of disposable foil, plastic and paper cups, clay cups have been widely used in India as single-use containers for a variety beverages foods. This is now changing. The cost, convenience transportability non-earthen has resulted their replacing containers. discusses gains losses from this substitution along three dimensions sustainability economic, environmental social, ...

Abstract The Iberian archaeological record is particularly rich in asynchronous (i.e. chronologically mixed) assemblages including Athenian pots that predate the other items by a couple of decades or even few centuries. Recent scholarship on keimëlia , ‘curated objects’ modern parlance, has shown potential such objects to investigate questions identity, agency and history-making among receiving...

A reconstruction of quantum theory refers to both a mathematical and conceptual paradigm that allows one derive the usual formulation from set primitive assumptions. The motivation for doing so is discomfort with theory, started its originator John von Neumann. We present finite-dimensional where all postulates are stated in diagrammatic terms, making them intuitive. Equivalently, they category...

Polylactide (PLA) is both bio?based and biodegradable has therefore attracted increased attention for single-use plastics applications. Under the context of recent EU Plastics Bioeconomy strategies, this study uses life cycle assessment (LCA) to assess environmental footprint drinking cups made from PLA, including 13 impact categories. Land use changes (LUCs) were assessed based on a determinis...

We finished the last lecture by discussing a physical zero-knowledge protocol for Graph 3-Coloring problem. In this protocol, the prover first generates a permutation π(w) of the 3-coloring w for instance graph G, where π(·) is a random permutation. He then colors G using π(w) and then hides the colored vertices of the graph using inverted cups. When the verifier issues a challenge (i, j), the ...

Eggs of Aedes albopictus were collected in oviposition cups from 3 forested areas of Delta State in south-central Nigeria during September 1991 as part of a post-yellow fever outbreak investigation. These eggs were shipped to the Centers for Disease Control in Colorado, where they were reared to the adult stage and identified. This is the first record of breeding populations of Ae. albopictus i...

People are tool-makers, but today we often depend on centralized fabrication for our tools. This paper explores the user experience opportunities demonstrated in a case study of a computer-controlled domestic fabrication system. Specifically we explore several approaches to creating a dish-maker that would create dishes on demand under computer control. The Dishmaker can create cups, bowls and ...
