Effect of crude fibre additives ARBOCEL and VITACEL on the physicochemical properties of granulated feed mixtures for broiler chickens

Urban Jakub,Michalczuk Monika,Batorska Martyna,Marzec Agata,Jaroszek Adriana,Bień Damian 아세아·태평양축산학회 2024 Animal Bioscience Vol.37 No.2

Objective: The aim of the study was to evaluate the physicochemical properties (nutrient composition, pH, water content and activity, sorption properties) and mechanical properties (compression force and energy) of granulated feed mixtures with various inclusion levels of crude fibre concentrates ARBOCEL and VITACEL for broiler chickens, i.e. +0.0% (control group - group C), +0.3%, +0.8%, +1.0%, +1.2%. Methods: The feed mixtures were analyzed for their physicochemical properties (nutrient composition by near-infrared spectroscopy, pH with the use a CP-401 pH meter with an IJ-44C glass electrode, water content was determined with the drying method and activity was determined with the Aqua Lab Series 3, sorption properties was determined with the static method) and mechanical properties (compression force and energy with the use TAHD plus texture analyzer). The Guggenheim-Anderson-de Boer (GAB) model applied in the study correctly described the sorption properties of the analyzed feed mixtures in terms of water activity. Results: The fibre concentrate type affected the specific surface area of the adsorbent and equilibrium water content in the GAB monolayer (p≤0.05) (significantly statistical). The type and dose of the fibre concentrate influenced the dimensionless C and k parameters of the GAB model related to the properties of the monolayer and multilayers, respectively (p≤0.05). They also affected the pH value of the analyzed feed mixtures (p≤0.05). In addition, crude fibre type influenced water activity (p≤0.05) as well as compression energy (J) and compression force (N) (p≤0.001) (highly significantly statistical) of the feed mixtures. Conclusion: The physicochemical analyses of feed mixtures with various inclusion levels (0.3%, 0.8%, 1.0%, 1.2%) of crude fiber concentrates ARBOCEL or VITACEL demonstrated that both crude fiber types may be used in the feed industry as a feedstuff material to produce starter type mixtures for broiler chickens.

Malignant Ameloblastoma : Prediction of Metastatic Potential Using In Situ Histone (H3) mRNA Analysis

Urban, Scott D.,Aram Elovic,Randy Todd,Gallagher, George T.,Donoff, R. Bruce,Wong, David T. W. Korean Academy of Oral Biology and the UCLA Dental 1998 International Journal of Oral Biology Vol.23 No.2

Malignant ameloblastoma is characterized by aggressive behavior and a poor prognosis. No histomorphologic criteria exist to differentiate malignant ameloblastoma from their benign, locally-aggressive counterparts. However, biological markers such as histone (H3) expression have proven to be an important indicator of bioaggressive potential and may be a useful predictor of disseminated ameloblastoma. We hypothesize that malignant ameloblastoma, while histologically identical to their benign counterparts, will have a demonstrably higher proliferation rate by histone (H3) mRNA labeling. Seven cases of formalin-fixed, paraffin-embedded tissues from surgical biopsies of mandibular follicular ameloblastomas were obtained. One of the seven specimens was obtained from an ameloblastoma which metastasized to the right and left lungs. Proliferation rates were determined using RNA in situ hybridization with ^35S-labeled histone (H3) antisense and sense riboprobes. A blinded correlative assessment was made between the labeling index of H3 and the clinical outcome. The quantitative tumor labeling index of the malignant ameloblastoma (HLI=0.329) was higher than the indices of the benign, locally aggressive ameloblastomas (HLI=0.049 to 0.111). This preliminary examination suggests that the basis of the rare metastatic behavior of ameloblastoma is possibly a reflection of an elevated cellular proliferation rate.

Cervical cancer patient reported gastrointestinal outcomes: intensity/ volumetric modulated vs. 3D conformal radiation therapy

Ryan Urban,Justin Wong,Peter Lim,Susan Zhang,Ingrid Spadinger,Robert Olson,Francois Bachand,Clement Ho,Anna V. Tinker,Lovedeep Gondara,Sarah Nicole Hamilton 대한부인종양학회 2022 Journal of Gynecologic Oncology Vol.33 No.5

Objective: To evaluate gastrointestinal (GI) patient reported outcomes (PROs) in cervical cancer patients treated with definitive radiotherapy (RT), comparing 3D conformal RT (3DCRT) vs. intensity modulated/volumetric modulated arc therapy (IMRT/VMAT). Methods: An analysis of patients treated with definitive RT between 2015–2018 was performed. GI PROs were prospectively collected at baseline, during RT (acute), ≤12 weeks after RT (subacute), and >12 weeks after RT (late). GI PROs evaluated three symptom domains: bowel problems (BPs), bowel bother (BB), and abdominal problems (APs). Multiple linear regression analysis was performed to investigate associations between mean changes of symptom scores with clinical and dosimetric variables. Results: The cohort included 167 patients. A total of 100 (60%) patients were treated with IMRT/VMAT and 67 (40%) with 3DCRT. In the subacute phase, the mean change of symptom scores from baseline in 3DCRT vs. IMRT/VMAT were +0.9 vs. −1.15 (p=0.004) for BP, +2.18 vs. −0.10 (p=0.019) for BB, and +1.41 vs. −0.38 (p=0.021) for AP. Likewise, in the late phase, mean changes were +0.72 vs. −0.82 (p=0.014) for BP, +1.98 vs. −0.03 (p=0.008) for BB, and +1.29 vs. −0.31 (p<0.001) for AP. On multiple linear regression, use of 3DCRT vs. IMRT/VMAT was associated with greater mean changes in subacute BP (p=0.023) and late phase AP (p=0.019). A higher small bowel V50Gy was associated increased symptom scores in late AP (p=0.012). Conclusion: 3DCRT was associated with significantly greater worsening of GI PRO symptom scores in the subacute and late phase. These data support the ongoing use of IMRT/VMAT in routine practice

A Sentence That Shaped the Modern World

Greg Urban 한국외국어대학교 HK 세미오시스 연구센터 2017 Signs and Society Vol.5 No.2

Tracking a single sentence as it moved around the globe, through space and across time, this essay examines the transformations it underwent, seeking to understand the motive force behind that movement and those transformations. The sentence in its various incarnations forms part of the constitutions of the majority of recognized nations on the planet. It encodes a key idea about the nature of the modern nation as a distinctive type of polity. At the same time, the motive force behind the movement may not be the power of that idea alone. Instead, the words in which it is encoded take on a thing-like quality, undergoing replication as they travel but also modification, such that the words become in effect emblems of a distinctive nation. The essay proposes that a “totemic force” impels this kind of motion, with the interest in being on a par with other nations stimulating recognizable similarities in wording, and the desire for distinctiveness vis-à-vis other nations simultaneously inspiring differences in wording.

Prediction of Microstructure in High-Strength Ductile Forging Parts

M. Urban,C. Keul,A. Back,W. Bleck,G. Hirt 한국소성가공학회 2010 기타자료 Vol.2010 No.6

Governmental, environmental and economic demands call for lighter, stiffer and at the same time cheaper products in the vehicle industry. Especially safety relevant parts have to be stiff and at the same time ductile. The strategy of this project was to improve the mechanical properties of forging steel alloys by employing a high-strength and ductile bainitic microstructure in the parts while maintaining cost effective process chains to reach these goals for high stressed forged parts. Therefore, a new steel alloy combined with an optimized process chain has been developed. To optimize the process chain with a minimum of expensive experiments, a numerical approach was developed to predict the microstructure of the steel alloy after the process chain based on FEM simulations of the forging and cooling combined with deformation-time-temperature-transformation-diagrams.

The Semiotic Corporation: An Introduction to the Supplement Issue

Greg Urban,Kyung-Nan Koh 한국외국어대학교 HK 세미오시스 연구센터 2015 Signs and Society Vol.3 No.-

The business corporation is explored as a reflexive cultural form shaped through complex and ongoing sign processes. The concern specifically is with the dynamic whereby external representations become internal to the corporation, shaping its form and operations, and, correspondingly, internally produced representations get projected outward into the world, mingling with other representations to influence how the corporation is construed. Seven contributions to this Signs and Society supplement are organized along a continuum—from the point of what is metaphorically conceptualized as the origo to the terminus, that is, from those studying the corporation as shaped through external representations, on the one end, to those presenting a view of how the corporation emerges through representations it projects outward on the other end.

Symbolic Force: A Corporate Revitalization Video and Its Effects

Greg Urban 한국외국어대학교 HK 세미오시스 연구센터 2015 Signs and Society Vol.3 No.-

A condensation symbol is a complex and relatively discrete bundle of icons, indices, and symbols, in the Peircean sense, that calls up affect and directs that affect toward social ends. This article analyzes a corporate motivational video produced by Harley-Davidson, Inc., an American motorcycle manufacturing company, as a condensation symbol. In addition to analyzing the formal features of the video, the article furnishes evidence, in the form of interview data, that the symbol is capable of influencing the orientations of individuals who view it. The “symbolic force” of the video is the force of interest that causes the orientation to the company carried by the symbol to be transmitted to its viewers. In this sense, the video resembles the dominant ritual symbols described by Turner. The present research also suggests, however, that the video summons distinct kinds of affect in different individuals, exerting a differentiating effect within social space.

The Role of Metaforces in Cultural Motion

Greg Urban 한국외국어대학교 HK 세미오시스 연구센터 2018 Signs and Society Vol.6 No.1

Exploring interactions among the forces (inertia, entropy, interest, and metaculture) that affect the motion of culture generally, this article focuses on metapragmatic indexicals as well as denotationally explicit metapragmatic signs, whose effects Silverstein dubbed “metaforce.” Pitch raising, as a metapragmatic indexical employed in narration, builds excitement in relationship to an unfolding stretch of mythic discourse, thereby contributing to the interest in that discourse that also impels its future replication. The interest in learning something new that drives the processes of replication underlying ordinary conversation can be aided by questions, as explicit metapragmatic formulations projecting the discourse shape of the desired response, just as explicit metapragmatic statements can be used to block expected replication processes in the flow of conversation, exerting a resistance. Interest can also be channeled from one discursive arena (such as wine talk) to another (such as coffee talk) through the process Silverstein calls “emanation,” based on similarities in the discourse form and content, a kind of metapragmatic iconicity. The article concludes by suggesting that similar processes are at work in disciplinary arenas, where Silverstein’s term “metapragmatics” itself has come to shape the entire field of linguistic anthropology and to be widely replicated elsewhere.
