Abstract:
Feed particle size influences digesta passage rate in broiler chickens, affecting ileal digesta viscosity. Measuring the viscosity of the ileal digesta is laborious but could be simplified with a model. This study evaluated the impact of feed particle sizes and multienzyme supplementation on ileal digesta viscosity in broiler chickens and developed an equation to estimate the ileal digesta viscosity using feed particle size and multienzyme supplementation as predictors. A total of 450 unsexed one-day-old Cobb500 broiler chicks were assigned to nine treatments with three particle sizes (3, 4, and 5 mm) and three levels of multienzyme supplementation (0, 1, and 2 g/kg), with five replicates per treatment, each containing ten birds. Data obtained were subjected to analysis of variance (ANOVA). Pearson correlation (r) between ileal viscosity, particle size, and multienzyme supplementation was performed to determine suitability for multiple linear regression, considering moderate correlation coefficients (r < 0.8) to avoid collinearity. Four models were generated using multiple linear regression. The best fit was determined by R² values, r, and p-values (p ≤ 0.05). The model Y = 0.2734 P + 0.0623 E was identified as the best fit, where Y is ileal digesta viscosity, P is particle size, and E is multienzyme supplementation level. In conclusion, larger feed particle sizes decrease ileal digesta viscosity. The derived equation effectively estimates ileal digesta viscosity in broiler chickens fed maize-based diets, using feed particle size and multienzyme supplementation as predictors. La taille des particules d’aliment influence le taux de passage du digesta dans le tube digestif des poulets de chair, affectant ainsi la viscosité du digesta iléal. La mesure de cette viscosité est fastidieuse, mais un modèle mathématique pourrait simplifier son estimation. Cette étude a évalué l’impact de la taille des particules d’aliment et de la supplémentation multi-enzymatique sur la viscosité du digesta iléal chez les poulets de chair. Elle a également permis de développer une équation permettant d’estimer cette viscosité en utilisant la taille des particules et la supplémentation multi-enzymatique comme variables prédictives. Un total de 450 poussins d’un jour Cobb500 non sexés ont été répartis en neuf groupes expérimentaux recevant des aliments à trois tailles de particules (3, 4 et 5 mm) et supplémentés en multi-enzymes à trois niveaux (0, 1 et 2 g/kg). Chaque groupe comprenait cinq réplicats de dix oiseaux. Les données obtenues ont été soumises à une analyse de variance (ANOVA). Une corrélation de Pearson (r) a été réalisée pour évaluer la relation entre la viscosité iléale, la taille des particules et la supplémentation multi-enzymatique. Cette analyse visait à garantir l’adéquation des variables à un modèle de régression linéaire multiple, en s’assurant de coefficients de corrélation modérés (r < 0,8) afin d’éviter la colinéarité. Quatre modèles ont été générés par régression linéaire multiple. Le meilleur ajustement a été déterminé en fonction des valeurs de R², du coefficient de corrélation (r) et de la valeur de p (p = 0,05). L’équation Y = 0,2734 P + 0,0623 E a été identifiée comme le meilleur ajustement, où Y représente la viscosité du digesta iléal, P la taille des particules et E le niveau de supplémentation multi-enzymatique. En conclusion, des particules d’aliment de plus grande taille réduisent la viscosité du digesta iléal. L’équation dérivée permet d’estimer efficacement la viscosité du digesta iléal chez les poulets de chair nourris avec des régimes à base de maïs, en utilisant la taille des particules d’aliment et la supplémentation multi-enzymatique comme facteurs prédictifs.

Abstract:
In this paper, the effect of ultrasonic wave on sizing materials is analyzed to optimize sizing properties. To give an overall view on the advantages of ultrasonic wave treatment in mixing and cooking , a range of solid contents are taken into account. By comparing with the traditional method of mixing and cooking, the relationships between sizing materials’(s) gelatinization temperature and time ,viscosity and viscosity stability are discussed. Experimental results have demonstrated that a certain ultrasonic frequency ( 40kHz ) in mixing and cooking method can reduce the gelatinization temperature and time, lower the viscosity of sizing solutions and increase viscosity’s stability.

Abstract:
An experimental investigation is conducted to clarify the hydrodynamic characteristics of ERF with elastic particles of smectite in a two-dimensional parallel duct of various widths. Experimental data on pressure difference to a volumetric flow rate in a supplying D.C. electric field are measured. These data are arranged to obtain the apparent viscosit by using the integral method of rheology. From the data of apparent viscosity, the wall friction coefficient is obtained. The increment of the apparent viscosity caused by the applying electric field is a function of shear rate as well as the electric field strength and the width of the duct. However, the wall friction coefficient is not a function of elecric field strength and the width of the parallel duct, but only of shear rate. The yield stress is a function of the width of the parallel duct as well as of electric field strength. The ratio of Non-Newtonian viscosity in the apparent viscosity is varied by the intensity of the shear rate.

Abstract:
The current problem of the production and processing of heavy high-viscosity oils in Ukraine and the world has been considered. It has been established that the main reserves of heavy high-viscosity crude oils in the world are located in South and North America, in the Middle East, as well as in Ukraine in the eastern regions. An analysis of various classifications of heavy high-viscosity oils, which are used both in Ukraine and in the world, was carried out. The main extraction methods of heavy high-viscosity oils were considered, in particular, quarry, mine, and well extraction methods. An overview of the technological processes of heavy high-viscosity oil processing was carried out.

Abstract:
Slags plays a significant role at high temperature processes. The estimation of the slag viscosity is vital for the safe run of e.g. entrained flow gasifiers. One opportunity of determination is rotational viscometry. This technique is disadvantageous in view of elevated temperatures, applied materials and the necessary time. Additionally, the viscosity can be predicted by the help of viscosity models, where viscosity is a function of slag composition and temperature. Due to changing slag properties within the technical processes, the calculated viscosities can hugely differ from measured ones. In this work, the viscosities of 42 slags where measured up to 100 Pa s and temperatures up to 1700 °C. Oxidizing and reducing conditions were applied. Additionally, selected slag samples were quenched at defined temperatures to qualitatively and quantitatively determine the formed minerals by X-ray diffraction (XRD). Differential temperature analysis (DTA) was applied to find the onset of crystallization for the complementation of investigations. The Einstein-Roscoe equation was chosen to improve the classic viscosity models. Reducing atmosphere decreased viscosity and the number of formed minerals was increased. Slags show a shear-thinning behavior above ca. 10 vol.-% of solid mineral matter. Also, Newtonian behavior was observed up to 60 vol.-%. To overcome problems with the kinetic cooling behavior of the slags, a viscosity approximation method was applied afterwards. This can result in optimized viscosity predictions when several preconditions are fulfilled.

Abstract:
Modern automobiles are painted with basecoat, technology which is either metallic, solid colour or pearlescent. This requires protection from chemicals, scratching, weathering and UV light by applying a protective top coat (clearcoat) over the basecoat. For the clearcoat to cure into a hard protective shell it undergoes an irreversible crosslinking process. This usually takes place over the first four to five hours, depending on the formulation and weather conditions. The speed of crosslinking can be enhanced by temperature. Pot life is important as it can affect the overall quality of the painted surface. If crosslinking occurs too quickly, before the clearcoat is applied onto the surface, the clearcoat cannot be used to produce a good quality finish. The “expired” mixture is thus discarded. If used, the quality of the finished product cannot be guaranteed to last, and the paintwork may have to be redone. This often means removing the underlying paint and primer as well with the clearcoat film. Besides the time lost, the discarded clearcoat mixture often lands in the landfill, polluting ground water and the environment. It is thus important from the point of view of both the environment preservation and waste management, that as much clearcoat as possible is used without being wasted. It was proven in an earlier study (BSc Hon Formulation Science Treatise, 2011) that adding eugenol to a clearcoat mixture after crosslinking had started could reduce its viscosity, which is an indicator of crosslinking progress. Crosslinking subsequently resumed at a lower rate than in traditional blends. If stored away from oxygen and high temperatures, this blend could maintain optimum viscosity indefinitely. In this follow up study an optimum formulation was developed using D - optimal experimental design. It sought to extend the pot life to avoid waste to spray painters while saving the environment from pollution. The formulation that gave the desired viscosity after five hours of pot life was adopted. It was hypothesised that the optimum formulated clearcoat mixture would have a longer pot life than its traditional counterparts, and that it would perform just as well as the traditional clearcoat mixtures. To study the rate of crosslinking (disappearance of functional groups and appearance of the urethane bond), FTIR spectrometry was performed on a mixture produced from the optimized formula in comparison to that of a traditional mixture (the control). The rate of disappearance of functional groups was found to be lower in the eugenol mixture than in the control mixture. After six hours, eugenol was added into the control mixture, and this seemed to reduce the viscosity with the re-emergence of functional groups in the mixture. After 24 hours of crosslinking, an FTIR scan was done on the solid sample and this revealed that the eugenol mixture had crosslinked fully, with no detectable functional groups in the sample.

Abstract:
Les travaux présentés s’axent autour de 2 chapitres indépendants : - le 1er concerne l’étude rhéologique d’une formulation pour SMC sans fibres. Cette étude permet d’élaborer des lois de comportement rhéologique. Ces lois sont ensuite insérées dans un code de calcul de simulation numérique afin de prédire les efforts mis en jeu lors d’une compression. Ces données simulées sont comparées avec des données de compression obtenues expérimentalement. - le 2ème se penche sur l’étude d’un comportement rhéologique rare : la rhéopexie négative. La viscosité de l’échantillon dépend de l’histoire de cisaillement qui lui est appliquée. Ce comportement est très sensible à la composition du mélange, et fait intervenir 4 constituants. Dès lors que l’un d’eux est retiré, le phénomène disparaît. Le mélange étudié est constitué de produits classiquement utilisés pour la production de SMC
The research presented is divided into 2 independents chapters: - the 1st one focuses on the rheological study of a fibreless formulation for SMC. This study allows us to write constitutive equations of the formulation. These equations are in turn implemented in a numerical simulation program, in order to predict the forces generated during a compression experiment. These simulated data are eventually compared with experimental data obtained during compression.- the 2nd chapter concerns the study of a rare rheological behaviour: the negative rheopexy. The viscosity of the sample depends on its shear history, in a very different way than a thixotropic sample’s viscosity would. This rheological behaviour is very component sensitive, and results from the interactions between 4 components. As soon as one of them is missing, the negative rheopexy disappears. The mixture studied is constituted of products traditionally used for the production of SMC

Abstract:
Abstract The most common viscosity models used in the drilling industry are the Bingham, the Power-Law and the Herschel-Bulkley models. The scope of the present paper is to outline how to select the individual models, and how the models need to be re-formulated to be able to have parameters with a physical meaning. In principle, the Bingham model itself have physical parameters being the yield point and the plastic viscosity. However, the Bingham model very often only very poorly describe the viscosity in complex fluids. This yield stress can be described within a reasonable accuracy by application of the low-shear yield point. A similar problem exists with the Power-Law model resulting from the model’s absence of a yield stress. The compromise model is the Herschel-Bulkley model which contains a yield stress and a power-law term. This model describes the drilling fluid viscosity with reasonable accuracy and includes both the Bingham and Power-Law models as limit formulations. It is not possible to select fluids based on the Herschel-Bulkley traditional parameters alone. The reason is that the Herschel-Bulkley power-law term’s viscosity parameter has a unit dependent on its power-law exponent. In the present approach the fluid is described using a yield stress, a surplus stress at a characteristic shear rate of the fluid flow and finally a power-law exponent making the fluid applicable in the practical shear rate ranges. The surplus stress is no-longer dependent on other parameters. Hence, we have re-arranged the viscosity model to have independent measurable quantities.

Abstract:
งานวิจัยนี้มีวัตถุประสงค์เพื่อศึกษาผลของพรีไบโอติก สารลดแรงตึงผิว และด่างต่อสมบัติของเพสต์และเจลสตาร์ชข้าวเจ้า ในการศึกษาผลของพรีไบโอติกต่อสมบัติของเพสต์และเจลสตาร์ชข้าวเจ้า สำหรับพฤติกรรมการเกิดเพสต์ของสตาร์ชข้าวเจ้า พบว่าชนิดของพรีไบโอติก (ฟรุกโตออลิโกแซ็กคาไรด์ หรือ FOS และ inulin) มีผลค่อนข้างน้อยต่อสมบัติการเกิดเพสต์ ในขณะที่ความเข้มข้นของพรีไบโอติกมีผลต่อสมบัติการเกิดเพสต์ โดยการเติมพรีไบโอติกทำให้ pasting temperature เพิ่มขึ้น แต่มีผลให้ peak viscosity, breakdown viscosity, final viscosity และ setback viscosity มีค่าลดลง สำหรับผลที่มีต่อการเกิดเจลาทิไนเซชัน พบว่าการเติมพรีไบโอติกทำให้อุณหภูมิเจลาทิไนเซชันของสตาร์ชข้าวเจ้ามีค่าเพิ่มขึ้นอย่างมีนัยสำคัญ (p≤0.05) และทำให้เอนทาลปีของการเกิดเจลาทิไนเซชันมีค่าลดลงเล็กน้อย ในแง่การเกิดรีโทรเกรเดชัน พบว่าตัวอย่างที่เติม inulin เข้มข้น 10% มีเอนทาลปีที่ใช้ในการหลอมผลึกแอมิโลเพกทินต่ำที่สุด เมื่อเปรียบเทียบระหว่างพรีไบโอติกที่ใช้พบว่าการเติม inulin ช่วยชะลอการเกิดเป็นผลึกใหม่ของแอมิโลเพกทินได้ดีกว่าการเติม FOS ผลที่ได้นี้สอดคล้องกับการเปลี่ยนแปลงของแรงที่ใช้ในการกดตัวอย่างเจลสตาร์ชให้แตกออกและปริมาณส่วนเสมือนของแข็ง ในส่วนการศึกษาผลของสารลดแรงตึงผิวต่อสมบัติของเพสต์และเจลสตาร์ชข้าวเจ้า พบว่าการเติมโซเดียมสเทียโรอิลแลกทิเลต (SSL) และกลีเซอรอลโมโนสเทียเรต (GMS) มีผลทำให้ peak viscosity, breakdown viscosity และ setback viscosity ลดลงอย่างมีนัยสำคัญ (p≤0.05) สำหรับอุณหภูมิการเกิดเจลาทิไนเซชัน พบว่าการเติมสารลดแรงตึงผิวส่งผลให้อุณหภูมิของการเกิดเจลาทิไนเซชันมีค่าลดลงอย่างมีนัยสำคัญ (p≤0.05) ยกเว้นสตาร์ชข้าวเจ้าที่เติม SSL ที่ความเข้มข้น 1.0% นอกจากนี้ยังพบว่าการเติมสารลดแรงตึงผิวไม่ส่งผลต่อการเปลี่ยนแปลงค่าเอนทาลปี ยกเว้นการเติม SSL ที่ความเข้มข้น 0.5% ซึ่งมีผลทำให้เอนทาลปีมีค่าลดลงอย่างมีนัยสำคัญ (p≤0.05) ในด้านการเกิดรีโทรเกรเดชัน พบว่าสำหรับการเติม SSL มีผลทำให้อุณหภูมิและเอนทาลปีของการหลอมผลึกแอมิโลเพกทินมีค่าต่ำกว่าตัวอย่างควบคุมอย่างมีนัยสำคัญ (p≤0.05) แต่สำหรับตัวอย่างที่เติม GMS พบว่าไม่สามารถสังเกตเห็นพีคการเปลี่ยนแปลงทางความร้อนที่เกี่ยวเนื่องกับการหลอมผลึกแอมิโลเพกทิน ในด้านแรงที่ใช้ในการกดตัวอย่างเจลสตาร์ชข้าวเจ้าให้แตกออก พบว่าตั้งแต่วันที่ 7 ของการเก็บรักษาตัวอย่างที่เติมสารลดแรงตึงผิวมีค่าแรงที่ใช้ในการกดตัวอย่างให้แตกออกต่ำกว่าตัวอย่างควบคุมอย่างมีนัยสำคัญ (p≤0.05) ส่วนในด้านปริมาณส่วนเสมือนของแข็ง พบว่าตัวอย่างที่เติมสารลดแรงตึงผิวมีปริมาณส่วนเสมือนของแข็งเพิ่มขึ้นอย่างมีนัยสำคัญ (p≤0.05) เมื่อเปรียบเทียบกับตัวอย่างควบคุม ในส่วนการศึกษาผลของด่างต่อสมบัติของเพสต์และเจลสตาร์ชข้าวเจ้า สำหรับพฤติกรรมการเกิดเพสต์ของสตาร์ชข้าวเจ้า พบว่าตัวอย่างที่เติมคันซุยมี pasting temperature สูงกว่าตัวอย่างควบคุม ในขณะที่ peak viscosity, breakdown viscosity, final viscosity และ setback viscosity มีค่าต่ำกว่าตัวอย่างควบคุมอย่างมีนัยสำคัญ (p≤0.05) ในด้านอุณหภูมิและเอนทาลปีของการเกิดเจลาทิไนเซชันของตัวอย่างสตาร์ชข้าวเจ้าที่เติมคันซุยด่าง พบว่าการเติมคันซุยมีผลทำให้อุณหภูมิเริ่มต้น อุณหภูมิสูงสุด และอุณหภูมิสุดท้ายของการเกิดเจลาทิไนเซชัน รวมทั้งเอนทาลปีของการเกิดเจลาทิไนเซชัน มีค่าเพิ่มขึ้นอย่างมีนัยสำคัญ (p≤0.05) ในการติดตามการเกิดรีโทรเกรเดชัน พบว่าตัวอย่างที่เติมคันซุยมีค่าอุณหภูมิสูงสุดและอุณหภูมิสุดท้ายของการหลอมผลึกแอมิโลเพกทินเพิ่มขึ้น แต่เอนทาลปีของการหลอมผลึกแอมิโลเพกทินมีค่าลดลง (p≤0.05) เมื่อเปรียบเทียบกับตัวอย่างควบคุม สำหรับแรงที่ใช้ในการกดตัวอย่างเจลสตาร์ชให้แตกออก พบว่าเจลสตาร์ชที่เติมคันซุยมีค่าแรงที่ใช้ในการกดตัวอย่างเจลให้แตกออกต่ำกว่าตัวอย่างควบคุมอย่างมีนัยสำคัญ (p≤0.05) และแรงที่ใช้ในการกดตัวอย่างเจลให้แตกออกมีค่าลดลงเมื่อความเข้มข้นของคันซุยเพิ่มขึ้น และในการวิเคราะห์ปริมาณส่วนเสมือนของแข็ง พบว่า ณ วันที่ 0 ตัวอย่างเจลสตาร์ชที่เติมคันซุย 0.5% มีปริมาณของส่วนเสมือนของแข็งสูงกว่าเมื่อเปรียบเทียบกับตัวอย่างควบคุม (p≤0.05) อย่างไรก็ตามเมื่อเพิ่มความเข้มข้นของคันซุยเป็น 1.0% พบว่าเจลที่ได้มีปริมาณส่วนเสมือนของแข็งต่ำกว่าเจลที่เติมคันซุย 0.5% และเมื่อเวลาการเก็บรักษาเพิ่มขึ้นทุกตัวอย่างมีปริมาณของส่วนเสมือนของแข็งเพิ่มขึ้น
