We show that, in the ideal-cipher model, triple encryption (the cascade of three independently-keyed blockciphers) is more secure than single or double encryption, thereby resolving a long-standing open problem. Our result demonstrates that for DES parameters (56-bit keys and 64-bit plaintexts) an adversary’s maximal advantage against triple encryption is small until it asks about 2 queries. Ou...

There is an enormous inequity in global health as well as research. Less than 10% of research funds are spent on the diseases that account for 90% of the global disease burden. This case study of north-south, south-south collaborations in Sri Lanka is a classic example of the issues faced by mental health researchers in low and middle income countries (LMICs). In this paper, work carried out by...

in the present investigation, shells of pistachio are used as adsorbents and they have been successfully used for the removal of blue 56, from water samples. the effect of various parameters such as: ph, amounts of adsorbents, size of adsorbent particles and contact time on removal processing were investigated. in this study freundlich absorption isotherms and langmuir were investigated . the e...

Teich's book will be of interest to three groups of readers. First, specialists in Systemic Functional Grammar (SFG) will find a detailed description of the use of SFG theory for a specific application, a discussion of some fundamental problems in the theory that are revealed by the application, and proposals for a modification of SFG theory to handle these problems. Second, those working in na...

abstract reference evapotranspiration (eto) is an essential parameter required for proper management of agricultural crop irrigation. eto is influenced by many different hydrological variables and as a result is a very complex procces. eto is usually estimated by empirical or process-orinented models (mathematical relationships) from historical weather data. the need for accurate estimates of e...

The development of ap integrated knowledge-based machine-aided translation system called PANGLOSS in collaboration with the Center for Machine 'Ikanslation (CMT) at CMU and the Computing Research Laboratory (CRL) at New Mexico State University. The IS1 part of the collaboration is focused initially on providing the system's output capabilities, primarily in English and then in other languages, ...

The gradient method used to estimate soil CO2 flux is distinctive because it can provide additional information about production and consumption of profile. However, choosing an appropriate gas diffusion model with confidence the a big challenge. There no universal optimal but only most suitable in specific soils. This paper evaluates applicability five commonly models laboratory changing prope...
