A data centre (10) includes one or more controllable air circulation systems (e.g. air optimiser (11)), one or more cold aisles (15) and/or one or more hot aisles (16), one or more rows of racks (14), the data centre being so arranged that in use cooling air (18) passes, under the control of the one or more controllable air circulation systems, from a cold aisle (15) through the racks (14) and/or through the racks (14) to a hot aisle (16). An access door (20), which provides access to at least one of the aisles, is movable between an open position allowing personnel access to the aisle and a closed position. The door (20) has an aperture (25) in which is provided a controllable air intake arrangement, for example comprising a vent (17) in the form of multiple vertically extending rotatable blades (28). The width (24) of the door is wider than the width (26) of the aisle associated with the door (20), so that the width of the aperture (25) may be larger than or substantially equal to the width (26) of the aisle. Air-flow into the aisle may therefore be subjected to less of a constriction than if the door (20) and aperture (25) were narrower.

A four-device-in-one skybox dehydrator sauna wind-redirecting bungalow comprises: adjustable louver blades attached to side gutter beams for preventing rainwater from getting into the bungalow and adjustably controlling amount of sunlight that shines into the bungalow, chutes formed to the side gutter beams and end gutter beams, solar-rechargeable batteries installed within adjustable louver blades for powering led lights and saving costs of replacing non-rechargeable alkaline batteries and helping reduce carbon footprint, a solar panel mounted to adjustable louver blades for collecting solar energy to charge and recharge rechargeable batteries and saving energy costs associated with lighting the bungalow and saving costs of replacing with non-rechargeable alkaline batteries and providing freedom to place the bungalow away from a power outlet and helping reduce carbon footprint, panel frames, panel inserts inserted within the panel frames for enabling the bungalow to become a sauna and a skybox and a dehydrator and providing security and insulation and protection from wind within the bungalow, louver braces inserted within the panel frames for allowing the louvers to be rotated, flipped, and positioned to redirect wind direction and structuringly securing louvers, axis pins inserted within the louver braces for providing eight locking points to reposition and locking and unlocking and pivotingly functionalizing the louver braces, louvers attached to the louver braces for redirecting and blocking and reducing and sealing the bungalow to create a sauna and a skybox and a dehydrator, an inner-track insert slidably inserted within hook-sliding track for providing a smooth sound-dampening track for slide hooks to be inserted for securing a curtain or insect screen, a curtain removably hooked onto slide hooks for providing privacy and protection from harmful sun rays and wind and insects, an extending-and-retracting door for providing protection from wind and harmful sun rays and insulation from cold temperatures and security within bungalow, door-spool housing attached to door-spool-housing bracket for providing discrete storage and protection of the extending-and-retracting door, drain openings formed into the corner-posts, corner-post-base-plate covers slidably attached onto the corner-posts, corner-post base-plates secured to the corner-posts, sliding-door track attached to the corner-post base-plates, the panel frames interchangably and slidably placed into the sliding-door track, anchoring-screw holes drilled into the corner-post base-plates, and tube-screws screwed into the anchoring-screw holes for leveling bungalow when installed on an uneven ground sur

A shutter including a frame, a first blade set, a second blade set, a power source and a blade driving system is provided. The frame has a frame body. The first blade set and the second blade set are disposed on the frame body of the frame. The power source is disposed in the frame body. The blade driving system connects the power source, the first blade set and the second blade set for rotating the first blade set and/or the second blade set to rotate.

Described is a louver having a frame that forms an enclosure defining an opening, and a plurality of louver blades disposed within the opening. Each of the plurality of louver blades include a catch member that longitudinally extends between a first blade end and a second blade end of a corresponding louver blade. The louver may also include a rotation assembly configured to rotatably couple with the plurality of louver blades and the frame. The plurality of louver blades may autonomously rotate about rotation members of the rotation assembly based on environmental elements captured in the catch member such that the plurality of louver blades are configured in an open position in response to no water in the catch member and are configured in a closed position in response to an amount of environmental elements in the catch member.

The present disclosure relates to methods of enriching beetroot products to increase the nitrate content of the beetroot powder product. The disclosure also relates to beetroot powder products with increased with at least 4% nitrate.

Aspects of the present disclosure are directed to apparatuses and related methods involving a screening apparatus and assembly. As may be implemented in accordance with one or more embodiments, an apparatus includes a plurality of panels, a frame and, for each panel, a locking mechanism coupled to the frame and a mechanical actuator connected to the panel and the frame. The locking mechanism locks the panel in place when engaged with the panel, and may do so at a different angle of rotation, relative to the other panels. The mechanical actuator positions the panel relative to the frame and offset from the other panels, and facilitates rotation of the panel about an axis of rotation that is fixed relative to the frame, in response to the panel being disengaged from the locking mechanism.

A window replacement panel including an air conditioning vent incorporated into it. A window assembly may be attached to a decorative panel with a vent disposed on a first side, and a coupling for an AC duct on an opposite side. The window may be a single, double pane, insulated, uninsulated or the like. The panel may be clad with material to harmonize with the building exterior, and the exterior vent presents a pleasing appearance. The combination of window and panel may be sized to replace an existing window, or may be used in new construction.
