The present work is an attempt to study the vibration analysis of the single-walled carbon nanotubes (SWCNTs) under the effect of the surface irregularity using Donnell's model. The surface irregularity represented by the parabolic form. According to Donnell's model and three-dimensional elasticity theory, a novel governing equations and its solution are derived and matched with the case of no irregularity effects. To understand the reaction of the nanotube to the irregularity effects in terms of natural frequency, the numerical calculations are done. The results obtained could provide a better representation of the vibration behavior of an irregular single-walled carbon nanotube, where the aspect ratio (L/d) and surface irregularity all have a significant impact on the natural frequency of vibrating SWCNTs. Furthermore, the findings of surface irregularity effects on vibration SWCNT can be utilized to forecast and prevent the phenomena of resonance of single-walled carbon nanotubes.

Murdoch's novel, The Black Prince, is not, as most critics have suggested, an autobiographical novel. It is about the inner life or rather trauma of Bradley Pearson, an artist who repeatedly dreams about a shabby paper shop which used to be run by his "unsuccessful" parents. In this respect, Freudian concept of trauma is helpful since it can explain Bradley's present repetition of his past traumatic experience, while allowing us to understand the nature of his trauma which reveals itself not only through his repeated nightmares but also through the women who are represented as diverse versions of his mother, the origin of Bradley's trauma. Caruth's concept of traumatic awakening and traumatic survival is also instrumental in understanding the nature of the traumatic experience which Bradley undergoes in this novel. Induced by Loxias's address, Bradley makes a confession of "the sins," which makes possible his traumatic survival as well as traumatic awakening, which is transmitted not only to Loxias but also to us the readers. In this sense, the significance of Bradley's awakening is not confined to his past only, but becomes a matter of a social dimension. The meaning of Bradley's writing lies in this fact.

This study aims to examine four machine learning (ML)-based models for their potential to estimate the splitting tensile strength (STS) of manufactured sand concrete (MSC). The ML models were trained and tested based on 310 experimental data points. Stone nanopowder content (SNPC), curing age (CA), and water-to-cement (W/C) ratio were also studied for their impacts on the STS of MSC. According to the results, the support vector regression (SVR) model had the highest correlation with experimental data. Still, all of the optimized ML models showed promise in estimating the STS of MSC. Both ML and laboratory results showed that MSC with 10% SNPC improved the STS of MSC.

BACKGROUND/OBJECTIVES: Fucoidan, a polysaccharide content in brown algae, has been reported to inhibit the growth of cancer cells. The present study aimed to investigate the suppression effects of fucoidan on A549 non-small cell lung cancer cells migration. MATERIALS/METHODS: The anti-migratory activity of fucoidan in A549 cells was examined by wound healing assay and phalloidin-rhodamine staining in response to fucoidan (0-100 ㎍/mL) treatment for 48 h. Western blot analysis was performed to clarify the protein expressions relevant to migratory activity. RESULTS: Fucoidan (25-100 ㎍/mL) significantly suppressed A549 cells migration together with reduced the intensity of phalloidin-rhodamine which detect filopodia and lamellipodia protrusions at 48 h of treatment. The protein expression indicated that fucoidan significantly suppressed the phosphorylation of focal adhesion kinase (FAK), Src, and extracellular signal-related kinase (ERK). In addition, the phosphorylation of p38 in A549 cells was found to be increased. CONCLUSIONS: Our data conclude that fucoidan exhibits anti-migratory activities against lung cancer A549 cells mediated by inhibiting ERK1/2 and FAK-Src pathway.

This paper presents results from a study of the effects of age and sex on body and carcass composition of different goat genotypes. A completely randomized $3{\times}3{\times}2$ factorial design was used. Factors were genotype (Thai Native; TN, $50%TN{\times}50%$ Anglo-Nubian (AN) and $25%TN{\times}75%AN$ goats), age ($206{\pm}8$, $349{\pm}9$ and $428{\pm}8days$ or 6.9, 11.6 and 14.3 months, respectively) and sex (male and female). It was shown that TN kids had significantly higher (p < 0.05) hind percentage (7.9%) compared with $50%TN{\times}50% AN$ (7.2%) and $25%TN{\times}75%AN$ (7.1 %) kids. TN kids had a significantly (p < 0.05) higher heart percentage (0.44%) than that of $25%TN{\times}75%AN$ kids (0.38%). However, there was no significant difference in heart percentage between TN and $50%TN{\times}50%AN$ and between $50% TN{\times}50%AN$ and $25%TN{\times}75%AN$ kids. TN and $50%TN{\times}50%AN$ kids had significantly higher (p < 0.05) carcass muscle content (63.1 and 63.7%, respectively) than did $25%TN{\times}75%AN$ kids (59.9%). Kids at 6.9 months of age had significantly higher percentages of hide, feet, intestinal tract, liver, heart, kidneys and carcass bone than those of kids at 11.6 and 14.3 months of age. There were no significant differences in these characteristics between kids at 11.6 and 14.3 months of age. However, kids at 11.6 and 14.3 months of age had significantly higher percentages of omental fat, dressing carcass, muscle, total fat (subcutaneous + intermuscular + kidney and pelvic fat), muscle to bone ratios (MBR), and muscle plus fat to bone ratios (MFBR) than those of kids at 6.9 months. Males had significantly higher gut contents, but lower percentages of liver, omental fat and heart. Prediction equations were developed relating empty body weight (EBW) to hot carcass weight and some dissectible carcass fractions.

Royal banquets under the reign of King Sunjo saw developments in the playacting stage, which exhibited characteristics unique to the transitionary period between Jeongjo and Gojong this period established the framework of the Joseon Dynasty's playacting stage construction. Starting with the Jagyeongjeon-Hall banquet and continuing into the Year of the Golden Rat banquet, the next-day banquet by the Crown Prince demonstrates a renewed format, with the stage also changing accordingly. This change was substantiated by more assertive use of the Red Blind and gabjang. Previously, the Red Blind has been installed in the palace hall and around the royal courtyard, to form three sides, but as next-day banquets became more frequent under Sunjo, the Red Blind developed and came to be installed in accordance with the hierarchy within the royal family. In the Year of the Golden Rat banquet, the Red Blind was lifted and the throne of the crown prince was situated in the palace hall. In the banquet of the following year, however, the Red Blind was let down and the crown prince's throne was placed outside, in palace court yard. This seems to have been a gesture to reorient the crown prince's political standing and restore Sunjo's sovereignty the following year. Hence, the installation of the Red Blind developed in accordance with the royal hierarchy and ranks under Sunjo's reign. The gabjang provided the second layer of protection for the playacting stage. The hongjeongju gabjang surrounded the stage in multiple layers and served as a partition. The gabjang from the Year of the Golden Bull banquet, in particular, boasted a unique installation, where it dangled from both sides of the royal palace's facade. Hongjeongju gabjang, lapis lazuli gabjang, red gabjang, and yellow curtains were installed in the stated order to reflect Sunjo's 40th birthday as well as the 30-year anniversary of his coronation. The Red Blind and gabjang from Sunjo's years were positioned in creative ways to reinstate the royal authority, and demonstrated many improvements from those of Jeongjo's reign.

Background: This case-control study aimed to determine if there were any associations between the two single nucleotide polymorphisms (SNPs) in Gc, rs7041 (Asp416Glu) and rs4588 (Thr420Lys) and 3 common cancers (breast, lung and colorectal) in Thai patients. Materials and Methods: Two hundred and eighty two colorectal, 101 breast and 113 lung cancer patients were recruited from one institute during 2011-2013. The controls were age-matched volunteers who had a negative history of index cancers. In addition, vitamin D levels were compared among different genotypes in the 2 SNPs. Results: The minor allele frequencies of rs7041 (G) and rs4588 (A) were 0.32 and 0.24, respectively. Under the dominant model, the study found significant associations between minor-allele genotypes of the SNP rs7041 (TG/GG) and lung cancer (odds ratio [OR] 1.78, 95% CI 1.05-3.03). When subgroup analysis was performed according to sex and age at diagnosis, the study found that the minor-allele genotypes of rs7041 (TG/GG) were significantly associated with colorectal cancer in patients whose age at diagnosis was more than 60 years (OR 1.67, 95%CI 1.06-2.61) and the minor-allele genotypes of rs4588 (CA/AA) were significantly associated with colorectal cancer in males aged 60 years or less (OR 2.34, 95%CI 1.25-4.37). When SNP combinations (rs7041-rs4588) were examined, the TT-CA combination had a significant protective association with lung cancer (OR 0.44, 95% CI 0.22-0.85). On evaluation of serum 25(OH)D levels in 205 individuals without cancer (males 144, females 61), the proportion of subjects with low serum vitamin D (< 20 ng/ml) in those harboring CA or AA genotypes of rs4588 (41.7%) was significantly higher than the CC genotype (15.5%, p-value < 0.01). Conclusions: Genetic polymorphisms in Gc were associated with lung and colorectal cancers in Thai patients. Lower serum 25(OH)D in minor variants of rs4588 may explain this association.
