Abstract: A process and system for treating wastewater is described. The invention degrades sludge produced by treatment of the wastewater to reduce or eliminate the need for sludge dewatering and disposal. The invention also reduces the amount of nutrient additives required to sustain the aerobic wastewater treatment process. In one embodiment the invention includes the steps of (a) providing an aerobic treatment system receiving a supply of the wastewater; (b) treating a supply of the sludge to rupture microbial cells present therein to produce treated sludge having an increased liquid:solid ratio and an increased degradation potential in comparison to untreated sludge; (c) conveying a supply of the treated sludge to the aerobic treatment system; and (d) substantially degrading the supply of treated sludge in the aerobic treatment system. The treated sludge may optionally be subjected to anaerobic digestion prior to delivery to the aerobic treatment system.

Abstract: An exemplary exercise device includes a handheld force sensor with complementary male and female connectors extending from opposite sides thereof. The force sensor senses pulling and/or pushing forces exerted between the opposing sides. The male connector may be resistant to travel through the female connector except in limited orientations. The connectors allow the exercise device to interface with any mobile or immobile device having complementary connectors. Non-complementary connectors can connect with the exercise device through a body passage. Depending on devices interfaced with the exercise device, force readings can be taken during a vast variety of motions using different muscle groups during training, exercise, and rehabilitation/physical therapy in homes, schools, healthcare facilities, health clubs, etc.

Abstract: A multicant winglet has a first blade section having a leading and a trailing edge, a first lowermost edge and a first uppermost edge, and a first central plane defined by the edges, and a second blade section having a leading and a trailing edge, a second lowermost edge and a second uppermost edge, and a second central plane defined by the edges. The first central plane is canted from vertical by a first cant angle, and the second central plane is canted from vertical by a second cant angle, the first cant angle unequal to the second cant angle.

Abstract: An exercise bar is configured to removably receive elastic lines, allowing its use in elastic resistance exercises, and/or inelastic lines, allowing its use in suspended bodyweight exercises. Separate grips, each being engageable by a hand or a foot, are also provided, and may be removably connected to the bar or to each other via one or more lines. Bar supports may also be provided to support the bar above the ground, allowing easy use of the bar to perform push-ups and other exercises.

Abstract: An exercise assembly includes an exercise handle with a grip base suitable for resting on a floor, and a grip elevated above the grip base. A user can situate the grip bases of a pair of the exercise handles on the floor, grasp their grips, and then perform push-ups. The grip bases can also be mounted to the top of a door or to other overhead structure, and the user can then grasp their grips to perform chin-ups. Preferably, this is done by providing a cradle which mounts to the door or other overhead structure, wherein the exercise handles may be firmly (but removably) nested into the cradles to mount them to the structure. The exercise handles may also bear passages or attachments for receiving elastic (or inelastic) cables for use in performing further exercises.

Abstract: A strap attachment device includes a main body with a lower body end that has an opening suited for a strap. Based on its position, a cam lever at the opening of the lower body end holds or releases the strap, permitting adjustment of the length of the strap that enters the opening. Extending upward from the lower body end is an upper body end that is curved into a hook or any other shape appropriate for connection to an object. A flexible or translatable gate may extend from the main body so as to prevent the upper body end from inadvertently becoming detached from the object. Slip-resistance on the upper body end resists slippage between the upper body end and the object during side-to-side movements. Ends of the strap may include a loop or handle or connect to other devices.

Abstract: An exemplary exercise device descending from an elevated support (e.g., a bar or door frame) allows a user to insert a body part in a loop (e.g., a foot for pull-ups or a waist for push-ups) descending from an elastic resistance unit, which uses a variable number of stretchable elastic members between top and bottom connectors to reduce the effective weight the user has to pull/push up. Each of the resistance unit top and bottom connectors has several elastic member sockets, each socket having a socket passage extending through the connector. Each elastic member has an elongated portion between two member plugs sized to resist passing through the elastic member socket passages. Elastic members can be removably and replaceably installed by inserting a portion of each member plug within an elastic member socket, one member plug in each of the resistance unit top and bottom connectors.

Abstract: An increase in effective propped lengths is evidenced in hydraulic fracturing treatments by the use of ultra lightweight (ULW) proppants. The ULW proppants have a density less than or equal to 2.45 g/cc and may be used as a mixture in a first proppant stage wherein at least one of the proppants is a ULW proppant. Alternatively, sequential proppant stages may be introduced into the formation wherein at least one of the proppant stages contain a ULW proppant and where at least one of the following conditions prevails: (i.) the density differential between the first proppant stage and the second proppant stage is greater than or equal to 0.2 g/cc; (ii.) both the first proppant stage and the second proppant stage contain a ULW proppant; (iii.) the rate of injection of the second proppant stage into the fracture is different from the rate of injection of the first proppant stage; or (iv.) the particle size of the second proppant stage is different from the particle size of the first proppant stage.

Abstract: Methods and compositions useful for subterranean formation treatments, such as hydraulic fracturing treatments and sand control that include porous materials. Such porous materials may be selectively configured porous material particles manufactured and/or treated with selected glazing materials, coating materials and/or penetrating materials to have desired strength and/or apparent density to fit particular downhole conditions for well treating such as hydraulic fracturing treatments and sand control treatments. Porous materials may also be employed in selected combinations to optimize fracture or sand control performance, and/or may be employed as relatively lightweight materials in liquid carbon dioxide-based well treatment systems.
