Preparation of Styrenated Phenol by Alkylation of Phenol with Styrene Over SO₄²⁻ /ZrO₂ Catalyst.

Styrenated phenols are usually synthesized by the reaction of styrene and phenol under acid catalysts. Styrenated phenol involving high content of di-styrenated phenol (DSP) was synthesized, which can be used to prepare styrenated phenol alkoxylate. The solid catalyst used in this study was prepared by impregnation method.

A Study on H₂SO₄-Treated MO Catalysts for Styrenated Phenols by Alkylation of Phenol with Styrene.

Styrenated phenols (SPs) involving very small amount of unreacted phenol and high content of di-SP (DSP) were synthesized, which can be used to prepare SP alkoxylate. The solid catalyst was prepared by impregnation method. SO2-4 on SO2-4/MxOy catalyst was introduced from an aqueous 1M-H2SO4 solution.

Demand-Driven Spatiotemporal Variations of Flow Hydraulics and Water Age by Comparative Modeling Analysis of Distribution Network.

Distribution network modeling is often used to investigate and manage water quality variations in a distribution network. It relies on pipe network simplification through skeletonization and uses water demand patterns that are often generalized or derived historical monthly water usage records. As automatic water meter reading and supervisory control and data acquisition (SCADA) technologies are widely used, it is possible now to explore the hydraulic complexity in the network.

A retroperitoneal dedifferentiated liposarcoma mimicking an ovarian tumor.

A 74-year-old postmenopausal woman visited our gynecology clinic complaining of a palpable abdominal mass. Physical and radiological evaluation indicated that the mass exhibited features of a left ovarian neoplasm showing heterogeneous enhancement. Surgical resection was performed to confirm this suspicion.

Transcriptomic variation in proanthocyanidin biosynthesis pathway genes in soybean (Glycine spp.).

Background: Proanthocyanidins are oligomeric or polymeric end products of flavonoid metabolic pathways starting with the central phenylpropanoid pathway. Although soybean (Glycine spp.) seeds represent a major source of nutrients for the human diet, as well as components for the cosmetics industry as a result of their high levels of flavonoid metabolites, including isoflavonoids, anthocyanins and proanthocyanidins, the genetic regulatory mechanisms underlying proanthocyanidin biosynthesis in soybean remain unclear.

Draft genome sequence of adzuki bean, Vigna angularis.

Adzuki bean (Vigna angularis var. angularis) is a dietary legume crop in East Asia. The presumed progenitor (Vigna angularis var.

Genome-wide SNP discovery in mungbean by Illumina HiSeq.

Mungbean [Vigna radiata (L.) Wilczek], a self-pollinated diploid plant with 2n = 22 chromosomes, is an important legume crop with a high-quality amino acid profile. Sequence variation at the whole-genome level was examined by comparing two mungbean cultivars, Sunhwanokdu and Gyeonggijaerae 5, using Illumina HiSeq sequencing data.

Molecular sequence variations of the lipoxygenase-2 gene in soybean.

Soybean lipoxygenase genes comprise a multi-gene family, with the seed lipoxygenase isozymes LOX1, LOX2, and LOX3 present in soybean seeds. Among these, the LOX2 isozyme is primarily responsible for the "beany" flavor of most soybean seeds. The variety, Jinpumkong 2, having null alleles (lx1, lx2, and lx3) lacks the three seed lipoxygenases; so, sequence variations between the lipoxygenase-2 genes of Pureunkong (Lx2) and Jinpumkong 2 (lx2) cultivars were examined.

QTL identification of flowering time at three different latitudes reveals homeologous genomic regions that control flowering in soybean.

Since the genetic control of flowering time is very important in photoperiod-sensitive soybean (Glycine max (L.) Merr.), genes affecting flowering under different environment conditions have been identified and described.

Whole-genome sequencing and intensive analysis of the undomesticated soybean (Glycine soja Sieb. and Zucc.) genome.

The genome of soybean (Glycine max), a commercially important crop, has recently been sequenced and is one of six crop species to have been sequenced. Here we report the genome sequence of G. soja, the undomesticated ancestor of G.
