The Pricing of Customized Industrial Products

The main objective of this study was to examine the pricing of customized industrial products in international markets, and to understand what pricing decision making consists of. Another purpose of the study was to identify the main factors that affect the pricing decisions of industrial companies, as well as the different pricing strategies industrial companies may choose when pricing customized products. The research was conducted as a qualitative single case study, and a Finnish industrial company specializing in indoor environment solutions, Halton Marine Oy, was used as the case company in the study. The primary data was collected through semi-structured theme interviews with the key management personnel of the company, and the results were discussed and analyzed in the light of the existing literature. The results of this study indicate that the pricing of customized industrial products consists of several dimensions, and is influenced by a large variety of factors that are both internal and external to the firm. In addition, it was found that the choice of a pricing strategy is largely dependent on the chosen segment, the product category, and the stage in the product life cycle. The results also suggest that customizing companies should consider using the value-based pricing orientation, since customization is closely linked to customer value.

Water quality and fish populations of the Welland River, Ontario /

The water quality and fish populations of the Welland River were observed to decline with distance downstream. This coincided with increased agricultural , domestic and industrial waste loadings. The river upstream of the City of Welland received considerable loadings from agricultural sources. Centrarchids, sciaenids, ictalurids, cyprinids and esocids characterized this upper section of the river. Most of these species were tolerant of low dissolved oxygen concentrations and the high turbidity which prevailed there . The river near Port Robinson receives many industrial and domestic wastes as evidenced by the water quality data. The fish in this section were less abundant and the observed population was comprised almost solely of cyprinids. Further downstream, near Montrose, the Welland River received shock loads of chemical wastes that exceeded a specific conductance of ISiOOO ;umhos/cm. Few fish were captured at this site and those that were captured were considered to be transients. A review of the literature revealed that none of the common indices of water quality in use today could adequately predict the observed distributions. In addition to the above, the long-term trend (l3 yrs) of water quality of the lower Welland River revealed a gradual improvement. The major factor thought to be responsible for this improvement was the operation of the Welland Sewage Treatment Plant. The construction of the New Welland Ship Canal coincided with large fluctuations of the total solids and other parameters downstream. These conditions prevailed for a maximum of three years (1972- 1975)' Furthermore, spawning times and temperatures, geographic distributions, length-weight regressions and many other descriptive aspects of the ecology of some 26 species/ taxa of fish were obtained. Several of these species are rare or new to southern Ontario.

Characterization of microalgae native to Quebec for biofuel production.

La production de biodiésel par des microalgues est intéressante à plusieurs niveaux. Dans le premier chapitre, un éventail de pour et contres concernant l’utilisation de microalgues pour la production de biocarburant sont ici révisés. La culture d’algues peut s'effectuer en utilisant des terres non-arables, de l’eau non-potable et des nutriments de base. De plus, la biomasse produite par les algues est considérablement plus importante que celle de plantes vasculaires. Plusieurs espèces on le contenu lipidique en forme de triacylglycérols (TAGs), qui peut correspondre jusqu'à 30% - 40% du poids sec de la biomasse. Ces proportions sont considérablement plus élevées que celui des huiles contenues dans les graines actuellement utilisées pour le biodiésel de première génération. Par contre, une production pratique et peu couteuse de biocarburant par des microalgues requiert de surpasser plusieurs obstacles. Ceci inclut le développement de systèmes de culture efficace à faible coût, de techniques de récupération requérant peu d’énergie, et de méthodes d’extraction et de conversion de l’huile non-dommageables pour l’environnement et peu couteuses. Le deuxième chapitre explore l'une des questions importantes soulevées dans le premier chapitre: la sélection d'une souche pour la culture. Une collection de souches de microalgues d'eau douce indigène au Québec a été établi et examiné au niveau de la diversité physiologique. Cette collection est composée de cent souches, que apparaissaient très hétérogènes en terme de croissance lorsque mises en culture à 10±2 °C ou 22±2 °C sur un effluent secondaire d’une usine municipale de traitement des eaux usées (EU), défini comme milieu Bold's Basal Medium (BBM). Des diagrammes de dispersion ont été utilisés pour étudier la diversité physiologique au sein de la collection, montrant plusieurs résultats intéressants. Il y avait une dispersion appréciable dans les taux de croissance selon les différents types de milieux et indépendamment de la température. De manière intéressante, en considérant que tous les isolats avaient initialement été enrichis sur milieu BBM, la distribution était plutôt symétrique autour de la ligne d’iso-croissance, suggérant que l’enrichissement sur BBM n’a pas semblé biaiser la croissance des souches sur ce milieu par rapport aux EU. Également, considérant que les isolats avaient d’abord été enrichis à 22°C, il est assez surprenant que la distribution de taux de croissance spécifiques soit aussi symétrique autour de la ligne d’iso-croissance, avec grossièrement des nombres égaux d’isolats de part et d’autre. Ainsi, l’enrichissement à 22°C ne semble pas biaiser les cellules vers une croissance à cette température plutôt que vers 10°C. Les diagrammes de dispersion obtenus lorsque le pourcentage en lipides de cultures sur BBM ont été comparées à des cultures ayant poussé sur EU soit à 10°C ou 22°C rendent évident que la production de lipides est favorisée par la culture sur EU aux deux températures, et que la production lipidique ne semble pas particulièrement plus favorisée par l’une ou l’autre de ces températures. Lorsque la collection a été examinée pour y déceler des différences avec le site d’échantillonnage, une analyse statistique a montré grossièrement que le même degré de diversité physiologique était retrouvé dans les échantillons des deux différents sites. Le troisième chapitre a poursuivi l'évaluation de la culture d'algues au Québec. L’utilisation de déchets industriels riches en nutriments minéraux et en sources de carbone pour augmenter la biomasse finale en microalgues et le produit lipidique à faible coût est une stratégie importante pour rendre viable la technologie des biocarburants par les algues. Par l’utilisation de souches de la collection de microalgues de l’Université de Montréal, ce rapport montre pour la première fois que des souches de microalgues peuvent pousser en présence de xylose, la source de carbone majoritairement retrouvée dans les eaux usées provenant des usines de pâte et papier, avec une hausse du taux de croissance de 2,8 fois par rapport à la croissance photoautotrophe, atteignant jusqu’à µ=1,1/jour. En présence de glycérol, les taux de croissance atteignaient des valeurs aussi élevées que µ=1,52/jour. La production lipidique augmentait jusqu’à 370% en présence de glycérol et 180% avec le xylose pour la souche LB1H10, démontrant que cette souche est appropriée pour le développement ultérieur de biocarburants en culture mixotrophe. L'ajout de xylose en cultures d'algues a montré certains effets inattendus. Le quatrième chapitre de ce travail a porté à comprendre ces effets sur la croissance des microalgues et la production de lipides. Quatre souches sauvages indigènes ont été obersvées quotidiennement, avant et après l’ajout de xylose, par cytométrie en flux. Avec quelques souches de Chlorella, l’ajout de xylose induisait une hausse rapide de l’accumulation de lipide (jusqu’à 3,3 fois) pendant les premières six à douze heures. Aux temps subséquents, les cellules montraient une diminution du contenu en chlorophylle, de leur taille et de leur nombre. Par contre, l’unique membre de la famille des Scenedesmaceae avait la capacité de profiter de la présence de cette source de carbone sous culture mixotrophe ou hétérotrophe sans effet négatif apparent. Ces résultats suggèrent que le xylose puisse être utilisé avant la récolte afin de stimuler l’augmentation du contenu lipidique de la culture d’algues, soit en système de culture continu ou à deux étapes, permettant la biorestauration des eaux usées provenant de l’industrie des pâtes et papiers. Le cinquième chapitre aborde une autre déché industriel important: le dioxyde de carbone et les gaz à effet de serre. Plus de la moitié du dioxyde de carbone qui est émis dans l'atmosphère chaque jour est dégagé par un processus stationnaire, soit pour la production d’électricité ou pour la fabrication industrielle. La libération de CO2 par ces sources pourrait être atténuée grâce à la biorestauration avec microalgues, une matière première putative pour les biocarburants. Néanmoins, toutes les cheminées dégagent un gaz différent, et la sélection des souches d'algues est vitale. Ainsi, ce travail propose l'utilisation d’un état de site particulier pour la bioprospection de souches d'algues pour être utilisé dans le processus de biorestauration. Les résultats montrent que l'utilisation d'un processus d'enrichissement simple lors de l'étape d'isolement peut sélectionner des souches qui étaient en moyenne 43,2% mieux performantes dans la production de biomasse que les souches isolées par des méthodes traditionnelles. Les souches isolées dans ce travail étaient capables d'assimiler le dioxyde de carbone à un taux supérieur à la moyenne, comparées à des résultats récents de la littérature.

The problem of unemployment of Women and poverty in India can be tackled effectively only through suitable and appropriate self-employment schemes. WICS help to supplement the income of families and thus raise the standard of living. WICS in Kerala have a significant role in the elimination of industrial backwardness and mounting employment. This study focuses its attention on the performance aspects of WICS. It also gives an introduction to the co-operative movement and review of literature on industrial co-operatives in general and women’s industrial co-operatives in particular.

Studies on the Role of Sediments on the Nutrient Dynamics and Fertility of Kuttanad Waters

In the present study the nutrient dynamics and fertility of Kuttanad waters is addressed. Kuttanad represent a wetland system with considerable agricultural activities. The hydrographical features of the Kuttanad waters are controlled by discharges from Manimala, Meenachil, Pamba, Achencoil and Muvattupuzha rivers and also by tidal intrusions of saline waters from Cochin backwaters during summers. The fertility of these water bodies were significantly high and supported good agricultural production. Kuttanad water forms the southern part of this aquatic systems and is considered as the most productive zones. As a part of the management scheme for a higher agricultural activity, the Thannermukkam bund was constructed to block and regulate the intrusion of saline water. The increased use of artificial fertilizers along with stagnant character of the water body in this area has resulted in sharp decline in the water quality, productivity and aquatic resources.

Standardization of Optimum Conditions for the Production of Glucosamine Hydrochiloride from Chitin

The study entitled standardization of optimum conditions for the production of glucosamine hydrochloride from chitin. Shellfish processing industries around the world turn out a significant quantity of head and shell as industrial waste. The waste must be removed immediately to prevent the contamination to the processing environment. The technique that are available for their disposal include ocean dumping, incineration or disposal of landfill sites. In this thesis the techniques and methods are used to process glucosamine hydrochloride from crustacean processing waste. Chitin is a nitrogenous polysaccharide, which is white, hard, inelastic, found in outer skeleton of insects, crabs, shrimp and lobsters and in the internal structures of other invertebrates. Glucosamine can be considered as a nutraceutical product by virtue of its properties. It is important for healthy skin, and plays a major role in the healing of surgical incisions and skin wounds. Deproteinisation of shrimp shell had significant effect on quality of chitin. Demineralization is also influences chitin quality. Solvents used for glucosamine hydrochloride affects the final yield and purity.

Studies on the Nature and Chemistry of Sediments and Water of Periyar and Chalakudy Rivers, Kerala, India

The present study is an attempt to address issues related to sediment properties like texture, mineralogy and geochemistry as well as water quality of two important rivers of central Kerala-the Periyar and the Chalakudy rivers. The main objectives of the study are to investigate the textural and mineralogical characteristics as well as transportation and depositional mechanisms of the sediments of Periyar and Chalakudy rivers, to find out the geochemical variability of organic carbon, phosphorus and certain major (Na,K,Ca and Mg) and minor/trace(Mn,Pb,Ni,Cr, and Zn) elements in the bulk sediments and mud fraction of these rivers, to evaluate the status of heavy metal pollution registered in the sediments of these rivers, to assess the physico-chemical characteristics and water quality of Periyar and Chalakudy rivers and to estimate the dissolved nutrient flux through the Periyar and Chalakudy rivers into the receiving coastal waters. The granulometric characteristics as well as statistical parameters of the sediments of Periyar and Chalakudy rivers depend on the flow pattern controlled by the gradient of the terrain. Compared to Periyar, fluctuations in the dispersal of particles are more in Chalakudy river. In Periyar river, the P and Fe in bulk sediments show a positive correlation with C-org, while in Chalakudy river, both the elements are related to THM concentration. In general, C-org, Fe and P Shows an increasing trend downstream. In Periyar river, the P and Fe in bulk sediments show a positive correlation with C-org, while in Chalakudy river, both the elements are related to THM concentration. Among these two rivers, the pollution of water is several fold higher in Periyar river due to influx due to influx of considerable quantity of liquid and solid wastes of industrial/domestic/urban origin. Nutrient analysis reveals 2-3 times increase in N and P during monsoon season whereas SiO2-Si shows a decreasing trend.

Surface Properties and Catalytic Activity of Manganese Ferrospinels

In recent years considerable advances have been achieved in the study of the surface structure and mechanism of action of environmentally benign heterogeneous catalysts. The study entitled as surface properties and catalytic activity of manganese ferrospinels. In the present study we have prepared manganese ferrospinels of general formula Mn(1-x)BxFe2O4 via low temperature controlled co-precipation method. The study employed low temperature co-precipitation method for the preparation ofMn(1-x)BxFe2O4 specimens, where B is a metal cation such as Cr,Co, Ni,Cu and Zn. The catalytic activities of the systems were investigated for liquid-phase benzoylation of aromatic compounds and phenol hydroxylation and for vapour-phase reactions such as aniline alkylation, phenol methylation and ODH of ethylbenzene. The different series of manganese ferrites are proved to be excellent catalysts for various industrially important reactions such as Friedel-crafts benzoylation of aromatic compounds, methylation of aniline and phenol, hydroxylation of phenol and oxidative dehydrogenation of ethylbenzene. Due to the tightening of the environmental regulations, production of diphenols from phenol hydroxylation and reduction of phenolic pollutants in waste waters using these catalysts can be a promising approach because it demands only simple techniques and produce little environmental pollution.

Systematics and biology of Fishes of family of the hemiramphidae of Cochin coast

This overall focus of the thesis involves the systematics and biology of fishes of the family hemiramphidae of cochin coast.India is one of the leading fish producing nations in the world with an average annual production of 6.1 million tonnes of fish and shell fish from capture and culture fisheries in 2001 (Ayyappan and Biradar, 2002).Fisheries play a very significant role in the Indian economy by providing employment to nearly 7 million people directly or indirectly, supplying rich protein food and earning valued foreign exchange.Fishes of the family Hemiramphidae are commonly called ‘half beaks‘.In India, studies on hemiramphids commenced with the work of Day (1878,1889) who recorded thirteen species of hemiramphids from the Indian waters.The study area, which is part of Cochin coast is located between Lat.9°28’ and 10° N and Long.76° 13’ and 76° 31 E. Lying parallel to it is an estuary which is commonly called the Cochin backwaters which has a total area of about 200 sq.miles.The study area is subjected to wide variations in salinity from place to place, season and surface to bottom.The Cochin coast and the adjacent back water system of Kerala has a rich and diversified fish fauna. The hemiramphid fishes constitute a minor fishery of this area.The study on the distribution and availability of hemiramphid fishes present in the Cochin coast shows that they evince different patterns of distribution.In the present study it is noticed that fecundity has high correlation with weight than length of the fish.Histological studies revealed that the spermatogenesis in both H. (H) limbatus and H.(H) xanthopterus, consists of spermatogonia, primary spermatocytes secondary, spermatocytes, spermatids and spermatozoa whereas in the oogenesis of both the species.biological study will be useful in implementation of proper measures of conservation and management so that further devastation of the hemiramphids of Cochin Coast can be controlled.

Echno economic studies on industrial fishing in the upper east coast of India

The present scenario of industrial fishing in India is that most of large trawlers are based at Visakhapatnam and congregate in the potential shrimp ground in the upper East coast of India commonly known as the Sandheads. These are outriggcr vessels operating two or four trawl nets along with a testing trawl called try net. In the early Seventies these vessels were operating on a very high economic return which was evident from the steady increase in number of outriggers over a period of twenty years. Since the total allowable catch has to be shared by all vessels including the increasing fleet, reduction per vessel output is bound to happen. Therefore some of them could not survive the competition and withdrew from the scene. The number of outriggers did not increase subsequently. However, there arose a doubt whether the existing fleet of about 180 vessels are fishing economically or whether there is any scope for further introduction of industrial vessels in the region. This study is focussing to the techno economic aspects of industrial fishing in the upper East coast of India
