Abstract: Cross-linked shear-thinning fluids of pectic acid demonstrating increased viscosity with decreasing shear, as well as methods of producing and using the same. A shear-thinning fluid includes an aqueous solution of pectic acid cross-linked by a divalent cation is disclosed. The pectic acid may be present in an amount ranging from about 0.5 to about 3.0% (w/v), the divalent cation may be present at a concentration of from about 0.5 mM to about 7.0 mM, and the viscosity of the shear-thinning fluid increases with decreasing shear. These cross-linked shear-thinning fluids of pectic acid can be utilized for controlled release formulations, cell encapsulation, and 3D printing, and provide for an improved balance between structure fidelity/mechanical stability and cell viability.

Abstract: In an embodiment, a content assembly platform (CAP) presents a structured user interface arranged for structured receipt of authored content. The CAP receives content for a content piece via the structured user interface. The CAP presents the received content via the structured user interface according to a set of predetermined content-display rules. The CAP stores the received content in a content management system (CMS) for online publication of the content piece according to the predetermined set of content-display rules. The CAP receives an instruction to publish the content piece to a print-production system, and responsively packages the received content in a print-production-system-readable format and transmits the packaged content to the print-production system.

Abstract: A paint tray bag is provided. The paint tray bag comprises a bag comprising dimensions for containing a paint tray, and optionally painting tools, therein. The paint tray bag further comprises a sealing apparatus for releasably sealing the bag, the sealing apparatus around at least portion of a perimeter of the bag such that the bag comprises a closed position for containing the paint tray therein when the sealing apparatus is closed and an open position when the sealing apparatus is open, the bag enabled to lay flat in the open position to act as a drop sheet for the paint tray. The paint tray bag further comprises an extended drop sheet which unfolds from the bag to provide an extended area for the drop sheet.

Abstract: An apparatus that is generally directed to a paint bucket cover, and specifically to a sealable paint bucket cover comprising structures to securely hold painting tools such as rollers or brushes within the container when the cover is in place, is provided. When not being accessed, paint containers need to be sealed to keep the contents from spilling, or the paint from drying out. Frequently, however, it desirable to be able to cover a paint container while painting tools are still in the bucket. The cover includes a panel comprised of at least a first surface and a paint tool holder, and a band for releasably connecting the cover to the paint container while creating a substantially air-tight configuration.

Abstract: The level of hydrogen sulfide in drilling fluid within a well formed in the Earth is assessed in an ongoing and/or in situ manner. The well may be constructed for the removal of hydrocarbons from the Earth. The assessment of hydrogen sulfide level may be provided in an ongoing manner such that real time, or near real time, fluctuations in hydrogen sulfide levels in the drilling fluid within the well may be conveyed to users. This may provide various advantages over systems in which drilling fluid must be extracted and separately tested for hydrogen sulfide content, and/or in which assessments of hydrogen sulfide level require time for performance.

Abstract: A paint spout is provided comprising: a hollow spout shaft comprising an insertion end and an oppositely disposed pouring end, the insertion end enabled for removable attachable insertion into a hole of a paint container, the pouring end enabled to direct paint pouring, through the hollow spout shaft; a strainer member; and, a strainer retaining portion for enabling a strainer member to be removably retained by the hollow spout shaft such that the paint poured there through is filtered by the strainer member, wherein the strainer member extends from at least one of: the pouring end of the hollow spout shaft; and, the insertion end of the hollow spout shaft.

Abstract: A point spout is provided. The paint spout comprises a hollow spout shaft comprising an insertion end and an oppositely disposed pouring end, the insertion end enabled for removable attachable insertion into a hole of a paint container, the pouring end enabled to direct paint pouring through the hollow spout shaft. The paint spout further comprises a strainer retaining portion at an interior surface of the hollow spout shaft for retaining a strainer member enabled for removable attachment to the interior surface of the hollow spout shaft such that the paint poured there through is filtered by the strainer member.

Abstract: Paint can straps and holders releasably attachable to a paint can are provided, such that at least one of fingers, a hand, forearm, and an arm can be inserted between a strap portion and the paint can, and along a longitudinal axis of the paint can, to leverage the paint can. The paint can holder includes a strap that is releasably attachable to the paint can. The strap can be attached to a harness, which is releasably attachable to the paint can. The harness can include a paint brush holder which can also be provided independent of the harness.

Abstract: A paint container cover is provided. The paint container cover comprises a lid portion enabled for removable attachment to a top of a paint can. The paint container cover further comprises at least one sealable opening in the lid portion for receiving a handle of a paint brush extending from the paint can such that the handle can extend from the top of the paint can through the sealable opening, the sealable opening enabled to prevent air from entering the paint can when the lid portion is attached thereto and the handle is extending through the sealable opening.
