This paper presents an architecture that allows multiple isolated commodity operating systems to run concurrently on a microkernel-based operating system without restricting the CPU architecture of guest operating systems. There are several systems that can execute multiple guest operating systems by using a virtual machine monitor or a microkernel-based operating system. Almost all of them, ho...

Sheffield where she at once found her way to the Workhouse. Correspondence as to her ultimate disposal thereupon ensued between the London County Council and the Sheffield Town Council. Four months later?August 7th 1919?she was, at her own desire, re-admitted to Alton as a voluntary case. She was thence transferred to a branch institution?the House of the Holy Rood, in Worthing? and was eventua...

Code sandboxing is useful for many purposes, but most sandboxing techniques require kernel modifications, do not completely isolate guest code, or incur substantial performance costs. Vx32 is a multipurpose user-level sandbox that enables any application to load and safely execute one or more guest plug-ins, confining each guest to a system call API controlled by the host application and to a r...

Sodium cholate aggregates are adaptable host systems. The effect of changing the ionic strength with the addition of NaCl on the properties for guest binding to sodium cholate aggregates was investigated by using pyrene, perylene and 1-ethylnaphthalene as guests. Fluorescence, anisotropy and laser flash photolysis studies provided information on the protection efficiency of the aggregate bound ...

All throughout history people have had the sense that products become more complex by incorporating new features or new technologies. Up to the middle of the 20th century, most products remained sufficiently simple that single people could design them. Now, all but the simplest products are designed by teams of people with different skills and expertise. Modern products span a range of traditio...

Commodity virtual machine monitors forbid direct access to I/O devices by untrusted guest operating systems in order to provide protection and sharing. However, both I/O memory management units (IOMMUs) and recently proposed software-based methods can be used to reduce the overhead of I/O virtualization by providing untrusted guest operating systems with safe, direct access to I/O devices. This...

Although Occupational Therapy in Iran is relatively a new profession, it has been well progressed, providing various services for people with all kinds of disabilities. As such, in the last decades, OT has been recognized as the major demand in all governmental, private and NGO sectors. Due to this demand, occupational therapy training programs have been increased from three into ten, expecting...

A pillar[5]arene-based bioactive guest loading system has been developed, which can increase the solubility of the drug norharmane in aqueous medium, and also enable its pH-stimulated release. Furthermore, this supramolecular transport system reduces the toxicity of loaded guest.

Hardware virtualization in the x86 architecture has enabled the use of virtual machine monitors in Beowulf clusters. In turn, each application user can then run a virtual guest operating system of his/her choice. Of course virtualizing and sharing the hardware resources in a Beowulf cluster will add additional overheads that may negatively effect performance of the application. However, the use...

Few methods currently exist for controlling vesicle-vesicle adhesion. We now report a new system, based upon a multivalent guest and an amphiphilic receptor with a photo-isomerisable anchor that can be incorporated into lipid vesicles of different sizes. Large unilamellar vesicles containing our receptor were found to aggregate upon addition of the multivalent guest, independently of photoswitc...
