A temporary radiotherapy facility for use during renovation, upgrading, and/or modernization of an existing facility. The radiotherapy facility includes a central vault room containing a radiation emitting device and a platform for holding a quantity of radiation shielding material above the central vault room. The platform is supported by shear walls that are disposed outside the sidewalls of the central vault room such that the radiation shielding material is supported and suspended above the central vault room without being in contact with or bearing upon the central vault room or affecting the height or level of the central vault room.

A method according to one embodiment includes securing a first plurality of conductive sheets to a surface, applying a conductive tape to a first plurality of joints between conductive sheets of the first plurality of conductive sheets, and securing a second plurality of conductive sheets to the first plurality of conductive sheets without fully penetrating the first plurality of conductive sheets. In such an embodiment, each of a second plurality of joints between conductive sheets of the second plurality of conductive sheets is offset relative to the first plurality of joints.

Rigid wall shelters are used throughout the world for shipping, living quarters, and housing for electronic systems and are energy inefficient. While investigating energy-efficient technologies for rigid wall shelters the discovery was made to insulate the outside of the shelter rather than the inside. Space is often limited inside of the shelter. The invention of an external, re-deployable insulation system was developed. The present invention is an insulating system composed of three main components. The first component is multiple, flexible envelopes filled with insulating materials (which creates a panel). The second component is multiple insulating strips that cover the joint between the panels. The final component is a weatherproof outer covering that protects the entire system from the elements.

A method and apparatus according to which a blast resistant shelter is assembled. The blast resistant shelter includes first and second structural members, a third structural member coupled to the first and second structural members, a first airway adjacent the third structural member, and a first blast panel pivotably mounted to the third structural member and adapted to pivot thereabout in response to a blast wave. In a first configuration, the first blast panel is detachably connected to a first portion of the blast resistant shelter and prevented from pivoting about the third structural member so that the first blast panel obstructs air flow through the first airway. In a second configuration, in response to the blast wave, the first blast panel is detached from the first portion of the blast resistant shelter and permitted to pivot about the third structural member to permit air flow through the first airway.

The present disclosure describes a strategy to create self-healing, slippery liquid-infused porous surfaces. Roughened (e.g., porous) surfaces can be utilized to lock in place a lubricating fluid, referred to herein as Liquid B to repel a wide range of materials, referred to herein as Object A (Solid A or Liquid A). Slippery liquid-infused porous surfaces outperforms other conventional surfaces in its capability to repel various simple and complex liquids (water, hydrocarbons, crude oil and blood), maintain low-contact-angle hysteresis (<2.5°), quickly restore liquid-repellency after physical damage (within 0.1-1 s), resist ice, microorganisms and insects adhesion, and function at high pressures (up to at least 690 atm). Some exemplary application where slippery liquid-infused porous surfaces will be useful include energy-efficient fluid handling and transportation, optical sensing, medicine, and as self-cleaning, and anti-fouling materials operating in extreme environments.
