The importance of the Louisiana Cooperative Extension Service as perceived by local governing bodies in Louisiana
… needs of local residents were being met by the LCES programs and services. Results of the study revealed that the local governing body members were more aware of 4-H than any other program or service offered by the LCES. Higher levels of awareness and effectiveness of programs and services …

Liquid Crystalline Elastomers as Renewable Functional Materials: From Chemistry to Application
Liquid Crystalline Elastomers (LCEs) are thermosets that belong to the family of “smart plastics”. They combine the softness and elasticity of elastomers, with the orientational order properties of liquid crystals (LCs), resulting in the ability for these materials to undergo large reversible …

Computation of Lyapunov Exponents and Control of a Hyperchaotic System
… spectrum relies on calculating the order-p LCEs and repeated application of the Gram-Schmidt orthonormalization procedure. We expect two positive LCEs for the Chen System. The program is adaptive to any n-th order chaotic and hyperchaotic systems. Controllers are then developed in order to …

Development of Liquid Crystalline Elastomers as Soft Mechanical Actuators
… Despite being studied for the past 30 years, LCEs have not yet been used in any real-world applications, which can be attributed to several problems: First, the external stimuli to trigger LCE actuation is demanding (i.e., stimuli can be difficult to deliver). Second, less desirable properties …

Development of applications of liquid crystalline elastomers from Materials to Applications
… the first generation of polysiloxane LCEs successfully introduced this wonderful material to the world; the second generation of LCEs deployed much more robust and easier synthesis procedure, bringing in researcher from many other disciplines; the third generation of LCE utilised the …

Epoxy + Liquid Crystalline Epoxy Coreacted Networks
… polymerization of liquid crystalline epoxies (LCEs) and a non-liquid crystalline epoxy has been investigated. Three LCEs: diglycidyl ether of 4,4'-dihydroxybiphenol (DGE-DHBP) and digylcidyl ether of 4-hydroxyphenyl-4"-hydroxybiphenyl-4'-carboxylate (DGE-HHC), were synthesized and blended with …

Paths Towards Shape Change: Elastic Instabilities and Spontaneous Deformations
… deformations in liquid crystal elastomers (LCEs) are two excellent examples of spontaneous deformations that can be patterned, allowing scientists to program shape changes, mimic biology and design soft robots. A typical example of patterned deformation is the morphing of flat sheets into …

The chromatin landscape of colorectal cancer cells
… lower-CTCF enrichment sites (PA-LCes) in colorectal cancer (CRC) cell lines as compared to primary colonic tissue from CTCF ChIP-Seq data. With ever-growing catalogues of nextgeneration sequencing datasets, including ChIP-Seq, in the public domain, the use of ENCODE datasets …

The Effectiveness of Literacy Coaches as Perceived by School Administrators, Classroom Teachers, and Literacy Coaches
… Literacy Coach Perceived Effectiveness Scale (LCES) was developed to measure perceptions of effectiveness using scores derived from 22 items. The SPELC was used to collect data from the participants to compare the effectiveness ratings of literacy coaches. Teachers ix rated the effectiveness of …

Adoption of best management practices in the Louisiana dairy industry
… with Louisiana Cooperative Extension Service (LCES) personnel, and producer's risk aversion on the increased adoption of BMP. Results also pointed out the need to address the lack of information regarding the legislation and the efforts to control nonpoint sources of water pollution through the …
