A new formulation to calculate the shakedown limit load of Kirchhoff plates under stochastic conditions of strength is developed. Direct structural reliability design by chance constrained programming is based on the prescribed failure probabilities, which is an effective approach of stochastic programming if it can be formulated as an equivalent deterministic optimization problem.

A copper-organic framework Cu2(BDC)2DABCO was synthesized, and used as a recyclable heterogeneous catalyst for C-N coupling reaction between benzamide and cyclohexane. 94% yield of N-cyclohexylbenzamide was achieved under the optimized condition. The copper-organic framework catalyst was truly heterogeneous and could be used at least 4 cycles without degradation of catalytic performance.

The reaction parameters including catalyst concentrations, reaction temperatures, molar ratio of p-anisidine/2,5- hexadione, and solvents, were systematically investigated. Almost 100% conversion was achieved under the optimized reaction conditions. The reusability of MOF-118 catalyst was studied. Furthermore, we demonstrated that the functional groups on aryl amines have strongly effect on the reaction rate.

Cryopreservation is an effective method for long-term storage of sperm. It is essential to investigate the optimal conditions for preserving semen for the purpose of artificial insemination. Cysteine has been proven to reduce the extent of sperm damage caused by oxidative stress during cryopreservation. The aim of this study was to determine the concentration of cysteine required for cryopreservation of goat semen. The experiment was carried out on 2 bucks with 4 treatments, each treatment repeated 8 times.

Treating dredged sediment is a complex processing and ongoing challenge. To utilize dredged sediment for the landfill or construction purposes, a material fabricated from a mixture of dredged sediment, Portland cement, and fly ash, was cured under room temperature and hydrothermal condition at 180 °C and 0.9 MPa pressure for 16 hours. The response surface methodology was used to evaluate the compressive strength of the material, with the range of factors investigated being the dredged sediments/solid ratio (0.3 - 0.9), cement/fly ash ratio (2 - 4), and water/solid ratio (0.45 - 0.55).

The results showed that the RPA reaction, without requiring complex thermal cycles, was well-performed in the optimal conditions of 39°C within only 25 minutes. The limit of detection was identified as 310 fg of L. monocytogenes genomic DNA, which was 1000-fold more sensitive than the conventional PCR. RPA also succeeded to directly detect L. monocytogenes cells at a concentration as low as 2.5 × 101 Colony Forming Unit (CFU)/mL in pure cultures. In addition, RPA could accurately detect L. monocytogenes at 2.5 × 102 CFU/mL in milk without sample extraction or processing.
