This paper presents the applying of sound barrier wall for highways in Viet Nam studied from existing experiments in the world. Nowadays, pollution sources come from traffic noises, water sources and air environment. Especially, traffic noises such as transportations, trains and airplanes are much serious and effect population and country. On road traffic systems, noise generated by vehicles is always in high level and give discomfort to residents who live around both sides of highways.

Early life exposure to adverse environments affects cardiovascular and metabolic systems in the offspring. These programmed effects are transmissible to a second generation through both male and female lines, suggesting germline transmission. We have previously shown that prenatal overexposure to the synthetic glucocorticoid dexamethasone (Dex) in rats reduces birth weight in the first generation (F1), a phenotype which is transmitted to a second generation (F2), particularly through the male line.

In this study, we propose an optical back propagation (OBP) approach for compensation of the nonlinear and dispersion distortions in direct-detection optical OFDM system. The proposed OBP using split-step Fourier method is implemented at transmitter that is suitable for high-rate OFDM-based LR-PONs applications.

The management of dairy farming has been historically based on experience and the skills the farm operator has in planning and decisions made. In cases where the farm has large herds, a farming system must be in place, thereby bring an evolution in dairy management, which is datadriven. Precision technologies can bring about increased efficiency and decision making in dairy management. Total farmers that have already adopted the technology is still relatively low, although data shows a growth in the adoption rate.
