Physical properties of simple and complex sugar systems.
No full textHoney, maple syrup and sugars during refining are examples of a complex solutions of concentrated sugars and other solutes. The physical properties of such systems are required for the design and optimization of processes and for the understanding of the behaviour of the final product. Literature shows limited data and even less rigorous analysis of the physical properties of concentrated sugar solutions. A fundamental thermodynamic approach provides an effective basis for the analysis and prediction of these properties. The main focus of this study was to consolidate physical property data for binary sugar systems, analyse the data using existing models, and propose newer models and equations to predict the physical properties of complex sugar solutions like honey.
In order to approach this, the physical properties density, viscosity, electrical conductivity, refractive index, mutarotation and water activity of binary solutions and sugar mixtures ranging from invert sugar solutions to model honey solutions with acid and salt were measured. Models that have been applied to sugar systems were reviewed. An equation for density based on the apparent densities of sugars in solution was validated. A viscosity equation that was extended from previous work with concentrated milk systems, was found to be very effective over the full concentration range of complex sugar solutions. Effects of viscosity on the electrical conductivity of sugar systems were analysed and a model was proposed for electrical conductivity in sugar systems. Hydration theory based on water activity measurements was applied to binary sugar systems and extended to model honey systems. Mixing theories were applied to the calculation of refractive index of solutions and also used as a tool to confirm the solid mass fraction in solutions.
The effect of mutarotation of sugars in viscous sugar solutions was studied using a new NMR technique that was validated using polarimetric measurements. In this study it was found that the mutarotation of glucose was not affected by the viscosity of the solution.
Past and new data and resulting equations provide a solid basis for future modelling and simulation of crystallization in these systems
Submerged mandibular carious deciduous second molar along with an impacted second premolar associated with an atypical inflammatory follicular cyst: A rare case report
No full textThe author presents a case of submerged carious deciduous molar along with an inflammatory atypical follicular cyst associated with an impacted mandibular second premolar in the right mandible identified through clinical and routine radiological examination including cone beam computed tomography and histopathology. The involvement of submerged deciduous molar with dental caries by itself a rare occurrence and an impacted permanent premolar tooth associated with an infected follicular cyst is still more a rare event

Fish Science Research in China: How does it Compare with Fish Research in India?
No full textFish and aquaculture research in the Peopleâ s Republic of China over the six years 1994-1999 has been mapped using data from six databases â three abstracting services and three citation indexes. The results are compared with fish science research in India. During the six years China has published 2035 papers (roughly 4.5 â 5% of the world output) and India 2454. More than 95% of Chinaâ s papers are journal articles, compared to 82.8% of Indian papers. About 78% of Chinaâ s journal paper output has appeared in 143 domestic journals compared to 70% from India in 113 Indian journals. Less than one-eighth of the journal articles published by Chinese researchers are published in journals indexed in SCI, compared to 30% of journal articles by Indian researchers. Less than a dozen papers from each of these countries have appeared in journals of impact factor greater than 3.0. Fish research institutes and fishery colleges are the major contributors of the Chinese research output in this area. In India academic institutions are the leading contributors (61%), followed by central government institutions (>25%). Qingdao, Wuhan, Beijing and Shanghai are the cities and Shandong, Hubei and Fujian are the provinces contributing a large number of papers. As we do not have addresses of all authors in most of the papers, we are unable to estimate the extent of international collaboration. Although Chinaâ s research output and its citation impact are less than those of India, Chinaâ s fish production and export earnings are far higher than those of India. Probably China is better at bridging the gap between knowhow (research) and do-how (technology and creation of employment and wealth). China is pretty strong in extension
Benefits and Challenges of Firm's Expansion to the European Market
No full textPředkládaná práce se zaměřuje na poskytnutí návodu pro vstup indické společnosti
na evropský trh. Diplomová práce je rozdělena do tří kapitol: První kapitola vysvětluje různé teorie, které je možné využít pro podnikání v jiné zemi, a také uvádí výhody, úskalí a problémy při expanzi podniku do zahraničí. Druhá kapitola popisuje jednotlivé metody a data, která byla použita ve třetí, praktické části práce.
V případové studii společnosti Lodestar 3D, představené ve třetí kapitole, byly
provedeny analýzy SWOT a PEST, jejichž cílem bylo identifikovat výhody a nevýhody, které by pro společnost znamenalo založení dceřiné společnosti v České republice. Výsledky těchto analytických nástrojů jsou doplněny informacemi získanými prostřednictvím polostrukturovaného rozhovoru s ředitelem společnosti Lodestar 3D. Hlavní závěr práce navrhuje společnosti Lodestar 3D jasněformulovanou obchodní strategii odkoupení české společnosti a vytvoření nové dceřiné společnosti mateřské společnosti, která sídlí mimo Indii (převodem licencí a povolení), a řešení všech klíčových problémů pro zahájení podnikání ve střední Evropě. Dodržování uvedených pokynů může společnosti pomoci zahájit podnikání a lépe sloužit evropským zákazníkům.The presented thesis focuses to provide a tutorial for the Indian company to enter the European economy. The diploma thesis is divided into three chapters: Chapter one explains the different theories which are available to use for doing business in another country and also lists the benefits, challenges, and problems for the company during its expansion abroad. Chapter two describes the various methods and data which were used in the third, practical part of the thesis.
In the case study of Lodestar 3D company, presented in the chapter three, the SWOT and PEST analyses were carried out to identify the advantages and disadvantages for the company to set up a subsidiary in the Czech Republic. The findings of these analytical tools are supplemented with the information gathered through the semi-structured interview with the director of Lodestar 3D. The main conclusion of the thesis proposes Lodestar 3D a clear-cut business strategy of buying out a Czech company and making it a new subsidiary of the parent company which is based out in India (by transferring licenses and permits) and addressing all the key challenges for starting the business in Central Europe. Following the specified guidelines can help the company to start the business and serve the European customers in a better way

Predicting the diffusivity of CO2 in substituted amines
No full textThe experimental determination of the diffusivity of carbon dioxide (CO2) in an amine solvent is difficult as the CO2 diffuses and reacts simultaneously when absorbed into an amine solvent. As the knowledge of the diffusivity and solubility of CO2 is essential to design the absorption units based on amine solvents, the nitrous oxide (N2O) analogy is used in practice to estimate them. It consists of evaluating those physical properties by substituting the reacting CO2 with an inert gas of a similar structure, N2O. The diffusion of CO2 in amine solvents is investigated using molecular dynamics (MD) simulation. Unlike experiments, MD simulation allows a direct measurement of the CO2 diffusivity. In MD simulations, the reaction between CO2 and the amine can be switched off. The Fick diffusion coeffcients are derived from the Maxwell-Stefan diffusivities and the thermodynamic factors. Different amine solvents like monoethanolamine, diethanolamine, methyl-diethanolamine and ethylamine are investigated. The N2O analogy in the monoethanolamine-water solution has been validated.EThChemical EngineeringApplied Science
