Dynamic response characteristics of an innovative turretless low motion FPSO hull in central GoM ultra-deep waters

Zou, Jun Techno-Press 2022 Ocean systems engineering Vol.12 No.2

In oil and gas industry, FPSO concept is the most popular hull form and ship shaped hull form dominants the FPSO market. Only a non-ship-shaped hull in operations with minor market shares is the cylindrical FPSO hull with medium to small storage capability. To add contracting options and competitions to reduce field development costs, an innovative turretless low motion hull, eco-FPSO, with 1MM bbls oil storage capacity and suitable for installing topsides modulars and equipping with regular SCRs, was first introduced in Zou (2020a). Dynamic characteristic responses of the eco-FPSO compared to the traditional SS-FPSO hull and DD-Semi platform are presented and discussed in this paper, suitability and feasibility of the proposed hull have been demonstrated and validated through extensive analyses in 10-yrp, 100-yrp and 1,000-yrp hurricanes in ultra-deepwater central GoM.

Yang Zou,XinPing Zou,XiZhi Li,Gang Guo,Peng Ji,Yan Wang,ShengLi Li,YaJing Wang,ZhiJun Cao 아세아·태평양축산학회 2018 Animal Bioscience Vol.31 No.3

Objective: The impact of forage feeding strategy on growth performance, ruminal fermentation and nutrient digestibility in post-weaning calves was investigated. Methods: Forty-five female Holstein calves (body weight [BW] = 79.79±0.38 kg) were enrolled in the 35-d study at one week after weaning and randomly assigned to one of three dietary treatments. All diets were fed as total mixed ration containing 60% (dry matter [DM] basis) of basal starter feed and 40% (DM basis) of forage, but varied in composition of forage source including i) alfalfa (40% DM, AH); ii) alfalfa hay (26.7% DM)+oat hay (13.3% DM; OH); iii) alfalfa hay (26.7% DM)+corn silage (13.3% DM; WS). Results: Dry matter intake was not different among treatment groups (p>0.05). However, BW (p<0.05) and average daily gain (p<0.05) of calves fed AH and OH were greater than WS-fed calves, whereas heart girth was greater in OH-fed calves than those fed AH and WS (p<0.05). Ruminal fermentation parameters including proportion of butyric acid, acetated-to-propionate ratio, concentration of total volatile fatty acid, protozoal protein, bacterial protein, and microbial protein in rumen were the highest in OH (p<0.05) and the lowest in WS. Compared with the AH and WS, feeding oat hay to postweaning calves increased crude protein digestibility (p<0.05), and decreased duration of diarrhea (p<0.05) and fecal index (p<0.05). Conclusion: Our results suggested that partially replacing alfalfa hay with oat hay improved ruminal fermentation, nitrogen utilization, and reduced incidence of diarrhea in post-weaning dairy calves.

자기 공명 영상을 이용한 안면비대칭환자의 측두하악관절 원반의 형태와 위치에 관한 연구

Bingshuang Zou,김태우,최순철 대한치과교정학회 2005 대한치과교정학회지 Vol.35 No.5

본 연구는 안면비대칭이 있는 환자의 측두하악관절원반 형태와 위치를 평가하고 악관절내장증과 안명비대칭 간의 관계를 규명하기 위하여 시행되었다. 남자 10명 및 여자 27명으로 구성된 안명비대칭 환자 37명의 74개의 TMJ MRI를 사용하였으며, 대상 집단의 연령은 12세에서 44세까지의 범위로 평균 21.4세였다. 시상 및 두정 TMJ MRI를 최대감합위 및 최대개구위에서 채득한 후 부분전방변위, 전방변위, 회전 또는 측방 원반변위 등 원반변위의 종류를 기록하였으며, 원반의 모양, 위치, 그리고 원반의 변위 및 회전을 MRI tracing 상에서 판독하였다. 악관절내장증의 증상은 정상, 정복성 전방원반변위 (ADDR). 그리고 비정복성 전방원반변위(ADDNR)집단으로 분류하였으며, 환자는 양측성 정상. 편측 혹은 양측 내장증 집단으로 분류하였다. 약 70%의 환자에서 편측성 또는 양측성 내장증을 보였으며, 통계분석 결과 ADD. 특히 회전성 ADD가 변위측에서 더 높은 빈도로 나타났으나 반대측에서는 원반의 위치가 정상인 경우가 많았다 (p<0.01).변위측의 원반은 모양의 변형 및 하전방 변위를 유의하게 더 나타냈다. 그러나 반대쪽은 개구시 원반이 수직방향으로 과운동성이 관찰되었다. 이 연구는 안면비대칭 환자에서 ADD의 종류가 원반의 모양,경사,변위 각도,변위의 수직거리 및 회전각도와 연관이 있다는 것을 제시한다. The present study was conducted to examine the morphometrics and function of the disk on both sides among patients with facial asymmetry (FA) and to elucidate plausible correlations between internal derangement (ID) and FA. The sample was composed of 10 males and 27 females with FA. The disk status of all subjects was evaluated by biateral high resolution magnetic resonance scans in the sagittal (closed and open) and coronal (closed) planes. Five types of disk displacement were identified accordingly. The disk function was diagnosed as normal disk function, disk displacement with reduction, and disk displacement without reduction. The disk shape on sagittal MRI in closed position was classified as bi-concave, biplanar, funnel/hemiconvex, and deformed. The disk position, translation and rotation were also measured. The difference between the shifted side and non-shifted side was analyzed by statistical analysis. Approximately 70% of the patients in the present study showed unilateral or bilateral ID. It was found that anterior disk displacements (ADD), especially rotational ADD, occurred more frequently in the shifted side, while normal disk position was observed mainly in the non-shifted side(p<0.01). The disk of the shifted side showed significantly deformed configuration and inferior-anterior disk position. However, the disk of the non-deviated side showed hyper-mobility during jaw opening movement. These results demonstrate that in FA patients, the disks status of the shifted side is different from that of the non-shifted side, a phenomenon that could be correlated to facial asymmetry.

Genetic Diversity and Population Structure of Peanut (Arachis hypogaea L.) Accessions from Five Different Origins

Zou, Kunyan,Kim, Ki-Seung,Lee, Daewoong,Jun, Tae-Hwan The Korean Society of Crop Science 2020 한국작물학회지 Vol.65 No.4

Peanut is an allotetraploid derived from a single recent polyploidization. Polyploidization has been reported to have caused significant loss in genetic diversity during the domestication of cultivated peanuts. Single nucleotide polymorphism (SNP)-based markers such as cleaved amplified polymorphic sequences (CAPS) derived from next-generation sequencing (NGS) have been developed and widely applied for breeding and genetic research in peanuts. This study aimed to identify the genetic diversity and population structure using 30 CAPS markers and 96 peanut accessions from five different origins. High genetic dissimilarities were detected between the accessions from Korea and those from the other three South American origins generally regarded as the origin of peanuts, while the accessions from Brazil and Argentina presented the lowest genetic dissimilarity. Based on the results of the present study, accessions from Korea have unique genetic variation compared to those from other countries, while accessions from the other four origins are closely related. Our study identified the genetic differentiation in 96 peanut accessions from five different origins, and this study also showed the successful application of SNP information derived from re-sequencing based on NGS technology.

魯迅の「示衆」と表現主義 ―感覚と表現の変容をめぐって―

Zou Bo 단국대학교 일본연구소 2019 일본학연구 Vol.56 No.-

This article started with a reinterpretation of Public Exhibition, Lu Xun’s short story with a focus on the writer’s relevance to expressionism through a probe into his initial encounter with this thought and his engagement in its translation. It aims mainly to explore the expressionist approach and its affinity with literature from the perspective of world literature through an analysis of the setting in which Lu Xun wrote the story and the writer’s own consciousness of expression. An exploration of Public Exhibition on the basis of the parameter of modern realist novels (realist novels) expressly reveals that contingency and subjective expressionism act as two backbones of the story in lieu of perspective and the modern novel structure based on the law of causality. The story, which is developed by vision, is framed through contingency and subjective observations with a negligible element of causality and causality‐based realism. It has made an attempt to transcend the overly‐meaning‐laden modernism by renunciation of realistic reproduction. Vision reigns as the motif rather than a means of thematic reflection. The writer metamorphosed it based on subjective observation and made its representation (corresponding to reproduction). Perceptual evolution, the prop of Public Exhibition as a modernistic genre, is the end product of novel epistemology and a new subject to be dealt with for the representation of the new genre. The story abounds in such figures of speech as metonymy, simile, personification etc., which the writer used as self‐expression of the objects under observation. 本稿では、魯迅が日本語を経由して表現主義に接し、翻訳した事実についての考察から出発し、表現主義との接点に着目しながら魯迅の短編小説「示衆」を読み直してみたい。論考は影響関係の追究ではなく、「示衆」を創作した魯迅を取り巻く芸術的な背景や魯迅自身の表現意識を検討して、「世界文学」という視点から20世紀芸術の大きな流れである「表現主義」の方法との類縁性を探ってみたい。 近代写実小説を参照系にしながら「示衆」を考察すると、遠近法に基づいた観察、「因果律」で構成された近代小説の構造は明らかに崩壊していることは明らかだ。「偶然性」の法則と主観的な表現は作品を支える二本の柱となっている。 視覚を中心に展開された「示衆」には、リアリズムが求めている因果律によって成立した「現実性」の要素は薄く、偶然性、主観的な観察によって構成された作品だと言える。「示衆」は現実主義風の「再現」を捨てて、現実に過剰な意味を付与していたリアリズムを超克する試みだと考えられる。視覚は主題を提示する手段ではなく、視覚そのものがテーマと化し、現実を主観的に把握し、変形させながら「表現」を目指す創作である。 モダニズムの文体の成立を支えるのは感覚の変容に起因している。感覚の変容は新しい認識論の結果であり、それを新しい文体で「表現」するのはこの作品に課せられた課題であった。「示衆」において多用された換喩、直喩、擬人法などを考察すれば、それは感覚的に観察した対象を主観的に表現しようとする創作手法でもあることは、もはや明らかだろう。

Integrated Metabolome and Transcriptome Analysis Reveal Complex Molecular Mechanisms Underlying Selenium Response of Aloe vera L.

Zou Yi,Changyou Han,Fang Wang,Yanhua Tan,Saina Yang,Chuying Huang,Shengyou Xie,Xueqin Xiao 한국식물학회 2021 Journal of Plant Biology Vol.64 No.2

Aloe vera L. is an excellent resource for medication. Selenium-enriched aloe can act as a functional food to human health. To understand the molecular mechanisms underlying selenium accumulation in Aloe vera L., we characterized the metabolic and transcriptome responses of aloe leaves under different Na2SeO4 levels (0, 200, and 400 mg/L) treatments. Aloe leaves spraying with exogenous selenium fertilizer showed a significant increase in total Se content compared with those under non-treatment control, and no distinct differences were observed between 200 and 400 mg/L Se treatment. Non-targeted metabolic profiling revealed that Se treatment triggered the accumulation of antioxidants, including amino acid and derivatives, phenols, flavonoids, terpene, as well as indole derivatives. Consistent with metabolic changes following Se treatment, the transcript level of genes involved in Se assimilation and Se-response showed dramatically increase, such as those encoding sulfate transporter, antioxidants, phytohormone signaling, transcription factors, and phenols metabolites, suggesting Se assimilation generally accompanied with antioxidant and pathogen defense. This study exhibited comprehensive insights on Se response in Aloe vera L., and provided us with targeted genes for genetic engineering, thereby improving the therapeutic value of aloe.

An improved radius-incremental-approach of stress and displacement for strain-softening surrounding rock considering hydraulic-mechanical coupling

Zou, Jin-Feng,Wei, Xing-Xing Techno-Press 2018 Geomechanics & engineering Vol.16 No.1

This study focused on the mechanical and hydraulic characteristics of underwater tunnels based on Mohr-Coulomb (M-C), Hoek-Brown (H-B) and generalized H-B failure criteria. An improved approach for calculating stress, displacement and plastic radius of the circular tunnel considering hydraulic-mechanical coupling was developed. The innovation of this study was that the radius-incremental-approach was reconstructed (i.e., the whole plastic zone is divided into a finite number of concentric annuli by radius), stress and displacement of each annulus were determined in terms of numerical method and Terzaghi's effective stress principle. The validation of the proposed approach was conducted by comparing with the results in Brown and Bray (1982) and Park and Kim (2006). In addition, the Rp-pin curve (plastic radius-internal supporting pressure curve) was obtained using the numerical iterative method, and the plastic radius of the deep-buried tunnel could be obtained by interpolation method in terms of the known value of internal supporting pressure pin. Combining with the theories in Carranza and Fairhurst (2000), the improved technique for assessing the reliability of the tunnel support was proposed.
