investigation of projectiles penetration phenomenon has been carried out in non-cohesive soil (sand) targets under dry, saturated and compacted conditions. analytical studies have been performed on the linear and non-linear soil models to obtain penetration depth formulae for ogival nose projectile and the results are verified by experimental studies. in present work, three ogival nose projecti...

when geotechnical engineers are faced with cohesive clayey soils, the engineering properties of those soils may need to be improved to make them suitable for construction. the aim of this paper is to study the effect of using lime, natural pozzolana or a combination of both on the geotechnical characteristics of two cohesive soils. lime or natural pozzolana were added to these soils at ranges o...

We have developed a cohesive extraction based single document summarizer (COHSUM) based on coreference links in a document. The sentences providing the most references to other sentences and that other sentences are referring to, are considered the most important and are therefore extracted. Additionally, before evaluations of summary quality, a corpus analysis was performed on the original doc...

This paper studies which social networks maximize trust and welfare when agreements are implicitly enforced. We study a repeated trust game in which trading opportunities arise exogenously and a social network determines the information each player has. We show that cohesive communities, modeled as social networks of complete components, emerge as the optimal community design. Cohesive communit...

These two case studies report how a cohesive short-stretch bandage was employed to promote venous leg ulcer healing. The two patients were obese and in addition had champagne bottle shaped legs. The cohesive short-stretch bandage was applied following the shape of the leg. By using a cohesive short-stretch bandage this provided bandage stability. This sustained compression resulted in oedema an...

We consider coherent and cohesive sheaves of O–modules over open sets Ω ⊂ Cn. We prove that coherent sheaves, and certain other sheaves derived from them, are cohesive; and conversely, certain sheaves derived from cohesive sheaves are coherent. An important tool in all this, also proved here, is that the sheaf of Banach space valued holomorphic germs is flat. To Linda Rothschild on her birthday

BACKGROUND In animal groups such as herds, schools, and flocks, a certain distance is maintained between adjacent individuals, allowing them to move as a cohesive unit. Proximate causations of the cohesive and coordinated movement under dynamic conditions, however, have been poorly understood. METHODOLOGY/PRINCIPAL FINDINGS We established a novel and simple behavioral assay using pairs of sma...

Dissociation energies have been determined for Al(n)(+) clusters (n=25-83) using a new experimental approach that takes into account the latent heat of melting. According to the arguments presented here, the cohesive energies of the solidlike clusters are made up of contributions from the dissociation energies of the liquidlike clusters and the latent heats for melting. The size-dependent varia...
