System for trapping and stretching biomolecules. A microfluidic device includes a symmetric channel forming a T-shaped junction at a narrow center region and three wider portions outside the center region. At least one power supply is provided to generate an electric potential across the T-shaped junction to create a local planar extensional field having a stagnation point in the junction whereby a biomolecule introduced into the microfluidic device is trapped at the stagnation point and stretched by the extensional field.

The employment identification method and software application of the present invention facilitates an employment search for a fulfillment of an open job opportunity wherein the employer is provided job seekers having a correlation between the skillsets required for the job and the experience/credentials of the job seeker. The present invention provides a process wherein the job seeker creates a profile account wherein the profile account includes all necessary information about the job seekers credentials and experience. The employer creates an account within the software application of the present invention and enters the requirements for their available employment opportunities. The software application of the present invention executes an algorithm to match the employment opportunity requirements and the job seeker skillset and credentials. Upon a correlated match, the employer is provided with the job seekers information. The present invention facilitates communication from the employer to the job seeker subsequent a correlated match.
摘要:
A collapsible carton, which may be flat-packed for storage but easily erected to form a many-sided box, and a blank (1) for forming such are disclosed. The carton comprises a base (2) having a plurality of base edges (13a, b, c), and a continuous sidewall (3) defining a base aperture for accepting the base (2), when the carton is erected. In a first aspect, the base (2) comprises two hingedly-joined base portions (11, 12), hingedly joined to the sidewall (3). The carton is characterised in that the base (2) is larger than the base aperture. In a second aspect, the sidewall (3) comprises a plurality of sidewall notches (26a, b, 36a, b). The carton further comprises an integral lid (4) having two lid portions (40, 50) hingedly joined to the sidewall (3). Both lid portions (40, 50) comprise two or more hingedly-joined wings (42a, b, 52a, b). Each wing (42a, b, 52a, b) comprises a wing notch (43a, b, 53a, b) adapted to cooperate with a corresponding one of the sidewall notches (26a, b, 36a, b) such that the lid portions (40, 50) may be secured in a closed configuration when the carton is erected.
摘要:
Apparatus and methods are described for achieving uniform stretching of polynucleotides in hybrid electrophoretic-gel, micro-constricting microfluidic channels. Polynucleotides in normally relaxed configurations are driven by an electric field along a microfluidic channel. The polynucleotides thread through a porous gel barrier formed in the channel and extend into a constriction where an electric field gradient exists. The combined action of the gel and field gradient acts to extend the polynucleotide configuration fully for direct linear analysis of the molecule.

An optical connector includes four main components, namely a clamp; a housing into which the clamp slides; two optical elements, a transmitter and a receiver; and an EMI metal shield surrounding the elements. The clamp has two parallel through holes for receiving fiber terminations, each through-hole having a generally conical mouth for convenient guidance of a fiber termination. Inside of the through-holes there are side resilient clamp members, and there is a single central clamp member. The clamp is of moulded plastics construction, and the clamp members are resilient in the lateral plane. The central clamp member on the other hand has little flexibility and remains essentially static throughout the clamping operation. Each resilient clamping member has a tooth at its end for snap-fitting engagement with the housing at open and closed positions. Fiber terminations are inserted through the clamp mouths and the through-holes and into the sockets of the housing. The clamp is then simply pushed inwardly so that teeth in the socket walls bite into the fiber claddings.

A computer-implemented method, system, and computer program product for performing object collocation on a computer system are provided. The method includes analyzing a sequence of computer instructions for object allocations and uses of the allocated objects. The method further includes creating an allocation interference graph of object allocation nodes with edges indicating pairs of allocations to be omitted from collocation. The method also includes coloring the allocation interference graph such that adjacent nodes are assigned different colors, and creating an object allocation at a program point prior to allocations of a selected color from the allocation interference graph. The method additionally includes storing an address associated with the created object allocation in a collocation pointer, and replacing a use of each allocation of the selected color with a use of the collocation pointer to collocate multiple objects.

An optimizing planer infeed system for feeding an array of workpieces downstream to a planer includes an apparatus for setting the size of the gaps between successive linearly aligned workpieces so that each gap between successive workpieces provides enough time for at least one of movable cutting elements in the planer and movable guiding elements to be moved to their optimized position corresponding to the next successive workpiece.

An optimizing planermill system includes a control system and a workpiece feed path for feeding an array of workpieces linearly downstream to an optimizing planer. The gap size between successive workpieces is set so that each gap provides enough time for relative movement of at least one of movable cutting elements in the planer and movable guiding elements so as to obtain relative movement between the cutting elements and the workpiece being next fed in for optimized positioning.
