In this study, Taguchi's experimental design method was used to improve the yield of FOX-7. Verification of the results shows that the optimal synthesis parameters are as follows: the molar ratio of HNO3/MPD is 8, the reaction time is 180 minutes, and the reaction temperature is 15°C; the maximum yield of FOX-7 can reach 79.14%.

To prepare the efficiently flame retardants (FR) for the highly flammable polymers, the novel nitrogen-phosphorus based FRs (P-N FR) (PN-3, PN-4, PN-5, and PN-6) were prepared via phosphorus halides and amine derivatives with 40- 90 % in yields. The appearance of P-N FRs are lightly white solid. All P-N FRs are water-insoluble and show a melting point above 40oC. The success of the synthesis was confirmed by NMR analysis.

This study was designed to extract a high yield of polysaccharides from the M. smilacifolium trunk and characterize it. As a result, the maximum yield of the polysaccharides of 5.13 ± 0.05% was obtained with an extraction time of three hours, extraction temperature of 100 oC, the ratio of water to sample of 1:50 as extraction solution, extraction number of times 3, and the ratio of ethanol to extract volume 5:1 (v/v).

In ebook "Precision in crop farming - Site specific concepts and sensing methods: Applications and results" high yields and environmental control in crop farming call for precise adaptations to local growing conditions. Treating large fields in a uniform way by high capacity machinery cannot be regarded as a sustainable method for many situations. Because differences existing within single fields must be considered.

Ebook "Iron nutrition in plants and rhizospheric microorganisms" provides comprehensive reviews on topics of plant-iron nutrition that are being addressed by different laboratories around the world. As one can see, the area of plant-iron nutrition is highly interdisciplinary, involving scientists of various fields of knowledge. Plant biologists are needed to characterize iron translocation throughout the plant following root iron uptake and to examine the regulation of iron-stimulated activities that influence crop yield and quality.

Tetrodotoxin analogues (TTXs) have been broadly applied in many fields. Viscera of pufferfish from Viet Nam was reported to contain a high level of TTXs, indicating a promising source for isolation of TTXs. In this work, critical factors affecting TTX recovery yield from pufferfish viscera collected from fishermen in the Can Gio coast of Viet Nam were optimized using response surface methodology (RSM).

Although the prognosis of locally advanced cervical cancer has improved dramatically, survival for those with stage IIIB-IVA disease or lymph nodes metastasis remains poor. It is believed that the incorporation of intensity-modulated radiotherapy into the treatment of cervical cancer might yield an improved loco-regional control, whereas more cycles of more potent chemotherapy after the completion of concurrent chemotherapy was associated with a diminished distant metastasis.

This specification covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction but intended primarily for use in welded bridges and buildings where savings in weight or added durability are important. The atmospheric corrosion resistance of this steel in most environments is substantially better than that of carbon structural steels with or without copper addition (see Note 1). When properly exposed to the atmosphere, this steel is suitable for many applications in the bare (unpainted) condition.
