Powder Metallurgy (PM) has advanced considerably during the last seventy years. This paper describes the conventional press & sinter process used for manufacturing highly sophisticated net-shape metal components. It highlights process advantages and the effects derived from material or process choices. Those choices must be understood when designing PM components since they significantly effect...

Overview Tracing is a set of diverse methods used to identify ammunition, its origins, and patterns of transfer. It is a prerequisite for successful ammunition management and a crucial means of identifying diversion and the illicit trade in all munitions. Tracing is contingent on being able to identify specific production runs, batches, lots, and other collections of ammunition, and to ascertai...

Conventional treatments of psoriasis include topical and systemic drugs. For sake of brevity, the presentation will deal only with systemic therapy. Three drugs are presently available in Italy: methotrexate, acitretin and cyclosporin A. Their efficacy is almost identical, all of them achieving PASI 75 in about 60% of cases in 12 weeks The indications (which, in Italy, do not include psoriasis ...

Conventional wastewater collection systems are installed to remove human wastes from households in cities and urban areas. This system demands high water supply rates as the wastes are flushed through pipes using water that flows under gravity. This system is capital extensive, and has been found to be not suitable in urban areas with smaller population sizes. Also, for the same reason, not sui...

Conventional Procrustes methods allow the analysis of morphology through the superimposition of one morphology onto another using the positions of landmark points. These methods are most useful for the comparison of pairs or small groups of specimens when it is of interest to describe one morphology in terms of deformation from another. When population analyses are of interest, generalized meth...

Overview Diversion is the unauthorized transfer of arms and ammunition from the stocks of legal users to the illicit market. Throughout the world, it sustains the activities of non-state armed groups, terrorist organizations, and armed criminality. It is one of the principal sources of illicit weaponry and represents a grave threat to the safety of civilian populations, as well as to the securi...

Today, a “computer”, without further qualifications, denotes a rather well-specified kind of object; we’ll consider a computer “non-conventional” if its physical substrate or its organization significantly depart from this de facto norm. Thus, the thousands of literate Greeks that ended up in Rome as secretaries and accountants after the “liberation” of Greece in the second century b.c. would b...
