Abstract: A flexible container has a bag body and a sealing portion at the upper end of the bag body's sidewalls. The sealing portion includes a strip and a groove which are relatively arranged on the inner side of the sealing portion. The strip has a convex mushroom-shaped cross-section, and the groove has a concave mushroom-shaped cross-section. The strip and groove interlock by an interference snap fit connection. The ends of the strip and groove transition from the mushroom-shaped cross-section to a rectangular-shaped cross-section which also snap fit together. The mushroom-shaped cross-section in the middle portion of the strip and groove create a sealing portion that is easy to seal and difficult to open. To help open the sealing portion, tabs extend up from the bag body's sidewalls. There is a cross-sectional transition design near the end, and the transitional shape can increase the sealing force to optimize the anti-leak effect.

Abstract: An electronic scale performs a post-weighing calibration in which the user steps on the scale, and the scale provides an estimated weight based on the scale's stored tare weight determined after the previous weighing performed by the scale. The person steps off of the scale while the estimated weight is displayed, and the scale automatically performs the calibration process to determine the scale's tare weight and verifies the weight. The estimated weight is shown with an orange ellipsis, and the verified weight is shown with a green checkmark. The scale compares the stored tare weight with the new tare weight, and if the difference between the stored tare weight and the new tare weight is within a variation threshold, the scale identifies the weight as being verified. If the difference exceeds the variation threshold, the scale recalculates the weight, displays the corrected weight, and produces a tone as an alert.

Abstract: The invention comprises a photoautotrophic organism, generally having simpler nutritional requirements than heterotrophic organisms, utilized as a chassis for the heterologous expression and function of enzymes, or derivatives of said enzymes, that show activity toward the degradation/detoxification of toxins known to be associated with and specific to harmful algal blooms. As an example, a cyanobacterial strain (Synechocystis sp. PCC 6803) modified to express Sphingomonas sp. USTB-05 MlrA enzyme functionality, showing the capability of degrading microcystins (results shown here) and nodularins, is presented. Under modelled natural conditions, results indicate that heterologous enzymatic activity against microcystin-LR is more stable over time when utilizing a photoautotrophic chassis in comparison to use of a heterotrophic bacterial strain. In addition, both the viability and cell density of the photoautotrophic host is maintained for a significantly longer period of time, compared to a heterotrophic host.
