The filter holding frame may include a plurality of interconnecting members with an upstream hemmed edge and downstream opposing flanges. The opposing flanges of the members may define a sealing face configured for a plurality of air filters. The members of the outer periphery of the filter holding frame may include the mounting surface and the sealing face.

Provided are: a vehicle cooling apparatus and a residential and office cooling apparatus, which are improved so as to prevent offensive odors and respiratory diseases by killing fungi and bacteria inside of a cooling part by means of hydrogen generated by electrolyzing the water condensed at the cooling part of the cooling apparatus; or a cooling apparatus and an air conditioning apparatus having a health-beneficial hydrogen generation device added thereto in which bacteria do not propagate since hydrogen is mixed and supplied to the interior air by means of a heat pump such that air quality is improved and the quality-improved air is supplied.

A modular vivarium is constructed entirely from transportable, sterile modules of distinct types, called pods. A hallway pod forms a spine, with cage-rack pods, ingress/egress pods and optional VHACPIT pods providing HVAC, power and IT services connected as spur pods to the hallway. Supplies and waste are also within modular pods. Temporary or single-use seals cover doorways during transit. Modules are joined or removed while maintaining sterility on both sides of the flush-to-wall doorway junction. Supply and return air for all pods is through hallway based ducting. Pods may be constructed from ISO intermodal containers. Embodiments have no permanent buildings. Pods may be moved, leveled and aligned for joining via special supports. Cage-rack pods are configured with two cage racks and a single isle permitting robotic cage placement and retrieval. Embodiments provide vibration, noise and earthquake isolation.

Systems and methods for monitoring and controlling activities of Drosophila organisms are provided. In one aspect, a method includes acquiring, using a first activity detector, imaging data tracking movements of the Drosophila organisms, and acquiring, using a second activity detector, bioluminescence data corresponding to a neural activity of the Drosophila organisms. The method also includes correlating, using the acquired data, a behavioral activity and neural activity of the Drosophila organisms, and determining, using the correlation, an activity profile for the Drosophila organisms. The method further includes providing, based on the activity profile, a stimulation to the Drosophila organisms to control at least one of the behavior activity or the neural activity over a time period extendible to a nominal life cycle of the Drosophila organisms.

A multi-layered metalized film for agricultural use comprising a reflective layer that comprises a metalized polyester film, acrylic polyurethane applied to the surface of the reflective layer, a bonding agent comprising a white-colored polyethylene material and a hindered amine light stabilizer that comprises a two and one-half percent ultraviolet light inhibitor, a fabric layer comprising a high density polyethylene woven fabric and an hindered amine light stabilizer, and a fabric layer coating applied to the surface of the fabric layer, the fabric layer coating comprising a white polyethylene coating material and an hindered amine light stabilizer.

An apparatus, system, and method are disclosed for a secure and comfortable animal enclosure providing convenient automated access and payment with validated User identification and validated animal identification linked to the animal's vaccinations and health records and configured for use in or near business, commercial, entertainment, workplace and other venues.

A fan for use in agriculture which has a BLDC motor which allows for varying the speed of the fan to vary the airflow rate of the fan and vary the efficiency of the fan. A ventilation system for use in a livestock confinement building to maximize a rate of growth of the livestock. A process for maximizing the growth of livestock in a livestock confinement building by controlling the airflow in the livestock confinement building.

The invention provides a lighting system (1000) for indoor microbiome management in an animal residence (200), wherein the lighting system (1000) comprises a light generating device (100), a control system (300), and an input system (305), wherein: the light generating device (100) is configured to generate first device radiation (111), wherein a spectral power distribution of the first device radiation (111) is selected for promoting persistence of the first microbes (7) relative to second microbes, other than the first microbes (7); the input system (305) is configured to receive and/or sense a microbiome influencing parameter and to provide a related input signal to the control system (300): the control system (300) is configured to control the light generating device (100) in dependence of the related input signal.

An improved poultry production method comprising providing dry hydrogen peroxide (DHP) to poultry eggs, chicks and birds, and devices for providing DHP to poultry production during laying, incubating, hatching, and growing.

A multifunctional animal exposure experimental device is provided. A multi-route transmission system is provided in an aerosol exposure system; an environmental temperature compensation system is provided in a biosafety system; an aerosol generation module communicates with a mixing chamber; the mixing chamber and a donor animal chamber alternatively communicate with a recipient animal chamber through an aerosol particle size screening module; an aerosol sampling system is connected to a sampling port of the mixing chamber, a sampling port of the donor animal chamber and a sampling port of the recipient animal chamber; an outlet of the constant temperature and humidity air producing device communicates with a first adjustment air inlet of the mixing chamber or a second adjustment air inlet of the donor animal chamber. This device enables quantification of transmission risks via different routes under controlled environmental conditions.
