Enhancing the oxidation resistance of graphite by applying an SiC coat with crack healing at an elevated temperature

Park, J.W.,Kim, E.S.,Kim, J.U.,Kim, Y.,Windes, W.E. Elsevier BV * North-Holland 2016 Applied Surface Science Vol.378 No.-

The potential of reducing the oxidation of the supporting graphite components during normal and/or accident conditions in the Very High Temperature Reactor (VHTR) design has been studied. In this work efforts have been made to slow the oxidation process of the graphite with a thin SiC coating (~10μm). Upon heating at≥1173K in air, the spallations and cracks were formed in the dense columnar structured SiC coating layer grown on the graphite with a functionally gradient electron beam physical vapor deposition (EB-PVD. In accordance with the formations of these defects, the sample was vigorously oxidized, leaving only the SiC coating layer. Then, efforts were made to heal the surface defects using additional EB-PVD with ion beam bombardment and chemical vapor deposition (CVD). The EB-PVD did not effectively heal the cracks. But, the CVD was more appropriate for crack healing, likely due to its excellent crack line filling capability with a high density and high aspect ratio. It took~34min for the 20% weight loss of the CVD crack healed sample in the oxidation test with annealing at 1173K, while it took~8min for the EB-PVD coated sample, which means it took ~4 times longer at 1173K for the same weight reduction in this experimental set-up.

A RANS modelling approach for predicting powering performance of ships in waves

Björn Windén,Stephen Turnock,Dominic Hudson 대한조선학회 2014 International Journal of Naval Architecture and Oc Vol.6 No.2

In this paper, a modelling technique for simulating self-propelled ships in waves is presented. The flow is modelled using a RANS solver coupled with an actuator disk model for the propeller. The motion of the ship is taken into consideration in the definition of the actuator disk region as well as the advance ratio of the propeller. The RPM of the propeller is controlled using a PID-controller with constraints added on the maximum permissible RPM increase rate. Results are presented for a freely surging model in regular waves with different constraints put on the PID-con-troller. The described method shows promising results and allows for the studying of several factors relating to self-propulsion. However, more validation data is needed to judge the accuracy of the model.

BACKGROUND: Congenital defects of the urinary bladder (micro- or contracted bladder, bladder exstrophy) remain a challenging problem for pediatric surgeons. Even when conservative treatment options are fully exhausted, irreversible renal dysfunction can be observed in a large number of cases that can even lead to chronic renal failure and the need for kidney transplantation. To protect kidney function bladder augmentation using intestinal tissue is commonly applied as the standard treatment method. However due to the unphysiological nature of intestinal tissue a number of problems and complications such as urinary tract infections or bladder stone formation limit the clinical success of this approach. Moreover a number of substitutes for the implementation of a bladder augmentation have been tested without success to date. Here we used an experimental model to test wether the biocompatible collagen mesh Lyoplant may be a suitable candidate for bladder augmentation. METHODS: We implanted a biocompatible collagen mesh (Lyoplant) in a bladder defect rat model for bladder augmentation (Lyoplant-group: n = 12; sham group n = 4). After 6 weeks the abdomen was reopened and the initial implant as well as the bladder were resected for histological and immunohistochemical examination. RESULTS: All but one rat exhibited physiological growth and behaviour after the operation without differences between the Lyoplant-group (n = 12) and the sham group (n = 3). One rat from the sham group had to be excluded because of a suture leakage. No wound healing complications, wound infections and no herniation were observed. After 5 weeks the implants showed an adequate incorporation in all cases. This was confirmed by immunohistological analyses where a significant cell infiltration and neovascularization was observed. CONCLUSION: In summary, Lyoplant appears to be a promising tool in experimental bladder augmentation/regeneration in rats.

Multiple elliptic gamma functions associated to cones

Elsevier 2018 Advances in mathematics Vol.325 No.-

<P><B>Abstract</B></P> <P>We define generalizations of the multiple elliptic gamma functions and the multiple sine functions, associated to good rational cones. We explain how good cones are related to collections of S <SUB> L r </SUB> ( Z ) -elements and prove that the generalized multiple sine and multiple elliptic gamma functions enjoy infinite product representations and modular properties determined by the cone. This generalizes the modular properties of the elliptic gamma function studied by Felder and Varchenko, and the results about the usual multiple sine and elliptic gamma functions found by Narukawa.</P>

Organizational Buying Behavior in an Interdependent World

Wind, Yoram,Thomas, Robert J. Korean Academy of Marketing Science 2010 마케팅과학연구 Vol.20 No.2

The emergence of the field of organizational buying behavior in the mid-1960’s with the publication of Industrial Buying and Creative Marketing (1967) set the stage for a new paradigm of thinking about how business was conducted in markets other than those serving ultimate consumers. Whether it is "industrial marketing" or "business-to-business marketing" (B-to-B), organizational buying behavior remains the core differentiating characteristic of this domain of marketing. This paper explores the impact of several dynamic factors that have influenced how organizations relate to one another in a rapidly increasing interdependence, which in turn can impact organizational buying behavior. The paper also raises the question of whether or not the major conceptual models of organizational buying behavior in an interdependent world are still relevant to guide research and managerial thinking, in this dynamic business environment. The paper is structured to explore three questions related to organizational interdependencies: 1. What are the factors and trends driving the emergence of organizational interdependencies? 2. Will the major conceptual models of organizational buying behavior that have developed over the past half century be applicable in a world of interdependent organizations? 3. What are the implications of organizational interdependencies on the research and practice of organizational buying behavior? Consideration of the factors and trends driving organizational interdependencies revealed five critical drivers in the relationships among organizations that can impact their purchasing behavior: Accelerating Globalization, Flattening Networks of Organizations, Disrupting Value Chains, Intensifying Government Involvement, and Continuously Fragmenting Customer Needs. These five interlinked drivers of interdependency and their underlying technological advances can alter the relationships within and among organizations that buy products and services to remain competitive in their markets. Viewed in the context of a customer driven marketing strategy, these forces affect three levels of strategy development: (1) evolving customer needs, (2) the resulting product/service/solution offerings to meet these needs, and (3) the organization competencies and processes required to develop and implement the offerings to meet needs. The five drivers of interdependency among organizations do not necessarily operate independently in their impact on how organizations buy. They can interact with each other and become even more potent in their impact on organizational buying behavior. For example, accelerating globalization may influence the emergence of additional networks that further disrupt traditional value chain relationships, thereby changing how organizations purchase products and services. Increased government involvement in business operations in one country may increase costs of doing business and therefore drive firms to seek low cost sources in emerging markets in other countries. This can reduce employment opportunitiesn one country and increase them in another, further accelerating the pace of globalization. The second major question in the paper is what impact these drivers of interdependencies have had on the core conceptual models of organizational buying behavior. Consider the three enduring conceptual models developed in the Industrial Buying and Creative Marketing and Organizational Buying Behavior books: the organizational buying process, the buying center, and the buying situation. A review of these core models of organizational buying behavior, as originally conceptualized, shows they are still valid and not likely to change with the increasingly intense drivers of interdependency among organizations. What will change however is the way in which buyers and sellers interact under conditions of interdependency. For example, increased interdependencies can lead to increased opportunities for collaboration as well as confli 20世?60年代中期, ?着1967年 ${\ll}$????和?造??${\gg}$的出版, ????行??一?域的?起?企?如何在市?中?作提供了新的思?方式, 而不只是?最?用?服?. 无?是 "工???" 或 "企???"(B-to-B),??的??行?仍然是???域的核心. 本文探?了??因素的影?,影?了????彼此相?的迅速增?的相互依存,反???影???的??行?. 文章?提出了一???,????行?的?念模型,在一?相互依存的世界是否仍然?在??充?活力的???境中引??究和管理的思想,. 本文提出?探索三??于??相互依存的??: 1.?些因素和????了??的相互依存的?起? 2.在?去半?世?中?展起?的????行?的主要?念模型仍然适用于今天??相互依存的??的世界?? 3.?究中??的相互依存的?示是什?? ????行?的??活?是什?? 考?到???系中????的相互依存的因素和??和5?????因素有??影?他?的??行?:加速全球化, 平整的????, 破?价??, 强化政府的介入, 不??分客?需求. ?五?相通的相互依存和?在的技?上的??可以改??????品和服?的市?中保持??力的?系. 在一?客???的??策略背景下, ?些力量影?三??次的?略?展: (1)?化的客?需求, (2)?生的?品/服?和解?方案以?足?些需求, 和(3)的??能力和工?制定和?施了以?足需求. ??中相互依存的五???因素在他?影???如何???不需要?立的操作. 他?可以相互作用和更加有效的影?????行?. 例如,加速了全球化的影?,出?了新的???一步破???价??之?的?系, ?而改?机???的?品和服?. 提高政府??可能?增加成本,因此在其??家的新?市??公司做生意?求低成本的?源. ?可以?少一?的就?机?增加?一??家的就?机?, 在?一方面, ?而?一步加速全球化. 第二?主要的??是相互依存的五???因素?????行?的核心?念模型有什?影?. 考?三?在 ${\ll}$????和?造??${\gg}$ 和 ${\ll}$????行?${\gg}$ ?籍中?展的?念模型:?????程, ??中心,以及??的情?. 回??些核心模型, 作?最初的?念,他?仍然是有效的, 而且不可能改?. 在?家和?家相互依?的情?下, 什??改????方相互作用的方式. 例如,增加了相互依?的机?可能?致增加?作以及??之?的?突的??,?而改????程. 此外,??中的?通?程的重要性作?一?成功的???系的判?依据?增加. 第三?????些????行?的?系的影?和意??行了探?. 以下是本文所考?到的: ?了增?????????行?的影?的理解,需要增加了解所扮演的角色之?的信任, 增强在???境中如何管理????的理解的需要, 需要增加了解在价???中的客?需要,?且需要增加了解新?的商?模式?????行?的影?. 在?多方面,?些?增加的??的相互依存派生出?的需要是????行????念的?展. 在1977年,Nicosia 和Wind建?把焦点集中在???而不是???部?点,自1990年以?, ????的???强. ?于管理者??,也想在越?越相互依存的世界中生存,他??需要更好地了解??如何??一??相?的??性. ???的相互依存的?点已??始,必?不?地?展提出一???些重要的?系改?的理解. 互相依?的???点的??需要?多??界人

Attract F, accusative Case-checking and the position of the subject in French Stylistic Inversion with Causative and Perception verbs

( Maarten De Wind ) 한국언어정보학회 1996 국제 워크샵 Vol.1996 No.-

A rather well-known aspect of French Stylistic Inversion is the impossibility of having a nominal object either precede or follow the inverted subject. A similar phenomenon is found is cases of French Stylistic Inversion with causative and perception verbs. The nominal subject of the infinitival complement can never appear with the inverted subject of the causative or perception verb. Both phenomena are usually referred to as Case-adjacency problems. In this paper, we will show that these Case-adjacency problems can be accounted for in a simple and straightforward manner under attract F and Procrastinate, two constraints on movement formulated in Chomsky`s Minimalist Program (Chomsky 1995, chapter 4).

Chromosomal Localization of Korean Cattle (Hanwoo) BAC Clones via BAC end Sequence Analysis

Chae, Sung-Hwa,Kim, Jae-Woo,Choi, Jae Min,Larkin, Denis M.,Everts-van der Wind, Annelie,Park, Hong-Seog,Yeo, Jung-Sou,Choi, Inho Asian Australasian Association of Animal Productio 2007 Animal Bioscience Vol.20 No.3

In this study, a Korean native cattle strain (Hanwoo) evidencing high performance in terms of both meat quality and quantity was employed in the generation of 150,000 BAC clones with an average insert size of 140 kb, and corresponding to about a 6X coverage of bovine chromosomal DNA. The BAC clones were pooled in a mini-scale via three rounds of a pooling protocol, and the efficiency of this pooling protocol was evaluated by testing the accuracy of accessibility to the positive clones, via a PCR-based screening method. Two sets of primers designed from each of two known genes were tested, and each yielded 2 or 3 positive clones for each gene, thereby indicating that the BAC library pooling system was appropriate with regard to the accession of the target BAC clones. Analyses of $3.3{\times}10^6$ base pairs obtained from the 7,090 BAC end sequence (BES) showed that 34.88% of the DNA sequence harbored the repetition sequence. Analysis of the 7,090 BES to the $1^{st}$ and $2^{nd}$ generation radiation hybrid map of the cattle genome, using the COMPASS program designed for the construction of a cattle-human comparative mapping, resulted in the localization of a total of 1,374 clones proximal to 339 $1^{st}$ generation markers, and 1,721 clones proximal to 664 $2^{nd}$ generation markers. Collectively, the BAC library and pooling system of the BAC clones from the Korean cattle, coupled with the chromosome-localized BAC clones, will provide us with novel tools for the excavation of desired clones for genome mapping and sequencing, and will also furnish us with additional information regarding breed differences in cattle.
