The purpose of this paper is to attempt to use two industrial wastes; waste foundry sands (WFS) and molasses (M) along with lime (L) to improve the strength characteristics of clayey soil.

In the first part of the study, the optimum percentages of materials (WFS, molasses, lime) have been found out by conducting differential free swell (DFS) and consistency limit tests on clayey soil by adding various admixtures. The second and third part of the study investigates the compaction behaviour and unconfined compressive strength (UCS) of clayey soil on addition of optimum amount of various materials alone and in combination with each other. Finally, the micro-structural behaviour of addition of optimum percentages of lime, WFS and molasses using Scanning electron microscopic technique has been discussed.

The laboratory results revealed that the addition of optimum content of lime along with WFS and molasses reduced DFS and plasticity index and increased maximum dry density and UCS values. The microstructural behaviour showed that the presence of lime and molasses filled the voids present in the soil and the addition of WFS helped in providing compact structure, thus improving the strength characteristics.

The study will be helpful in designing low-cost pavement designs for rural roads.

The adverse effect of waste materials on environment may be solved by using them in improving the strength characteristics of clayey soils, thereby providing healthy environment to living beings.

The study will help to provide low-cost methods to improve strength characteristics of clayey soil along with the use of waste materials; the disposal of whose is a challenging task.

The purpose of this paper is to investigate the efficacy of bacterial exopolysaccharides (Eps) in reactive black 5 (RB5) textile dye wastewater bioremediation.

The Eps were produced by bacteria isolated from cotton gin trash soils collected from different cotton-growing regions in Kenya for comparison purposes. A broth medium reconstituted using molasses was assessed for its capacity to produce the Eps. RB5 textile dye wastewater was optimized for dye removal under different temperatures, times and molasses concentrations. Dye removal was studied by Lovibond-Day Light Comparator, UV–Vis spectrophotometer and FTIR.

It was found that cotton gin trash soils contained Eps-producing bacteria. Three of the Eps studied were found to have the capacity to remove at least 80% of the dye from the wastewater.

This research did not assess the efficacy of the RB5 dye removal from the wastewater by mixtures of the Eps.

Bioremediation of textile dye wastewater with Eps produced by bacteria cultured from cotton gin trash soil is significant because it will offer an effective and cleaner alternative to the chemical coagulants.

Alternative treatment of textile wastewater with the Eps would result in safer water being released into the water bodies as opposed to the chemically treated wastewater that contains remnant chemicals.

Research on the use of Eps produced by bacteria isolated from cotton gin trash soils for removal of RB5 dye from textile wastewater has not been done before.

New product development (NPD), entrepreneurship and strategic management.

Advanced undergraduate, MBA/MSc in Marketing and Management course that cover the topics on NPD.

This case illustrates that commercialization of a new product requires a proper strategic direction to make it a reality. The case fact is positioned in livestock feed industry centered on commercialization of a newly developed urea-molasses mineral block (UMMB) or called Nutriblock. Dr Wan, a Senior Principal Research Officer of Malaysian Agricultural Research and Development Institute (MARDI), developed food supplement for ruminants which contained urea, molasses, vitamins, minerals and other nutrients. Dr Wan believed that the UMMB was a better quality food supplement compared to products in the markets because it contained 12 raw feed ingredients and an anthelmintic medication. After almost 10 years of research, in 2003, Dr Wan completed his research and, thus, wanted to get a suitable way to commercialize this product. He had two options: commercializing the technology through licensing of intellectual property right (IPR), or to transfer it as a public domain. The Business Development Unit(BDU) was responsible for the former option, whereas Centre for Promotion and Technology Transfer (CPPT) was in charge for the latter. At the beginning of2006, MARDI decided to commercialize the Nutriblock through licensing the IPR to March Avenue Technology Sendirian Berhad (March Avenue), a newly formed company. March Avenue was formed byKarthiir, a lawyer and Ma Irwan, an electrical engineer. The operation was going smoothly for the first two years. However, problem started in 2008 when Karthiir left the company due to some disagreement with Ma Irwan. Since then, March Avenue failed to achieve its sales target that seriously affected its profit level. Moreover, it suffered from internal management problem. The company finally closed down at the end of 2009. By this four year of operation, March Avenue failed to pay any royalty to MARDI. This circumstance forced Dr Wan to think seriously about his next move regarding choosing the right way of commercializing his Nutriblock. MARDI requested him to give his opinion by January 15, 2010 about whether to give another chance to BDU to commercialize this technology through IPR or to go for public domain under CPPT?

Using this case, students can learn that new product development and its commercialization requires proper strategic directions. It illustrates the importance of managing the commercialization of a new product effectively. NPD involves many stages, and it is important to manage every stage properly. This is because a “high-quality product” and/or a “new to the market” product are not enough to succeed in the market. In other words, producing a “product that meets market needs” must be combined with appropriate strategies.

The information which has hitherto appeared in the daily press as to the evidence laid before the Departmental Committee which is inquiring into the use of preservatives and colouring matters can hardly have afforded pleasant reading to the apologists for the drugging of foods. It is plainly the intention of the Committee to make a thorough investigation of the whole subject, and the main conclusions which, in the result, must bo forced upon unbiassed persons by an investigation of this character will be tolerably obvious to those who have given serious attention to the subject. At a later stage of the inquiry we shall publish a full account of the evidence submitted and of the Committee's proceedings. At present we may observe that the facts which have been brought forward fully confirm the statements made from time to time upon these matters in the BRITISH FOOD JOURNAL, and amply justify the attitude which we have adopted on the whole question. Representatives of various trade interests have given evidence which has served to show the extent to which the practices now being inquired into are followed. Strong medical evidence, as to the dangers which must attach to the promiscuous and unacknowledged drugging of the public by more or less ignorant persons, has been given; and some medical evidence of that apologetic order to which the public have of late become accustomed, and which we, at any rate, regard as particularly feeble, has also been put forward. Much more will no doubt be said, but those who have borne the heat and burden of the day in forcing these matters upon the attention of the Legislature and of the public can view with satisfaction the result already attained. Full and free investigation must produce its educational effect ; and whatever legal machinery may be devised to put some kind of check upon these most dangerous forms of adulteration, the demand of the public will be for undrugged food, and for a guarantee of sufficient authority to ensure that the demand is met.

About the year 1806 or 1807 consumers of cane sugar, and particularly those in central Europe, began to find out that there was very little of this kind of sugar to be obtained. Naval warfare and Napoleon's Continental System had resulted in something very like a sugar famine; and the only means of relief appeared to be either to extend and improve the existing methods of producing sugar from the beetroot or to discover new sources of saccharine matter from materials furnished by Europe itself, and so to make Europe independent of supplies of overseas sugar. Napoleon—the master of Europe at that time—made it his first care to provide, as far as possible, for the needs of the people of France; and French chemists were ordered and encouraged to undertake researches with the view to finding a more or less efficient substitute for cane sugar and molasses. The first step which was taken in the direction of relieving the situation was taken by Proust, who turned his attention to the possibilities inherent in grape juice. After a little time he had so well succeeded in his research that he was able to present the people of France with a sort of treacle, and with this it appears the masses had to be contented for about four years; refined cane sugar had become somewhat of a luxury. The use of molasses was the common practice in Germany—where the cost of moist sugar had been about fifteen pence a pound for some years before the time we are referring to. Proust's treacle must have proved an exceedingly poor article, and Napoleon, realising that human endurance of this would not survive for long, appointed a Committee, with the celebrated Chaptal as its head, to consider the best means of introducing the manufacture of beet sugar into France. Chaptal had succeeded Lucien Bonaparte as Minister of the Interior in 1801. He was the President of the Society for the Encouragement of National Industries, and in all respects he was well qualified to supervise a public enquiry of such importance. Marggraf's discovery in 1747 had already been taken advantage of to some extent in Prussia, and Achard of Berlin and others were already cultivating the beetroot and obtaining small quantities of beet sugar. After an interval of three or four years, during which careful examination had been made of the Prussian methods and results with beet sugar, Chaptal was able to send in a favourable report to Napoleon regarding their probable success in France. Events then moved rapidly. By Imperial decree 32 thousand hectares, say 80 thousand acres, of French soil were at once sown with beet. An absolute embargo was placed on all overseas sugar; and in the same year (1811) Chaptal was created Count de Chantaloupe. The start of the beet sugar industry in Europe may be said to date from this time.

Innovation cannot come without in‐depth understanding of the product and its consumer perception. This paper aims to show the approach for consumer‐centric re‐development strategy, from design of the experiment to execution, analysis, modeling and strategies for implementation.

The approach described uses a relatively large‐scale experimental design of ingredients (12 variables) to vary sensory attributes and conduct sensitivity analysis with consumers.

The resulting product was a big marketing success for the producer. A disciplined experimentation based on statistically sound experimental designs produces much better food products with increased acceptability by consumers.

Statisticians have turned their attention to modeling the relations between physical variables and subjective consumer responses. The resulting products are optimized to meet sensory preferences of the consumers including varied sensory segmentation of the markets.

Using advanced multivariate experimental design for sensory optimization has proved many times its advantages although still not universally used. The approach could help the marketers and developers create better products that consumers like.

There is a certain type of British trader who, with pharisaic unction, lifts up his voice and deplores the unhappy condition of “the heathen in his blindness,” including all persons of other nationalities and any of his own who may happen to differ in opinion from himself. On these collectively it is his habit to bestow his contemptuous regard when from his elevated position he condescends to thank Providence that as far as the methods and conduct of business are concerned he is “not as other men.” Of course, most people recognise that the attitude assumed by this type of person is one for which it is difficult altogether to blame him. Born as he was in an atmosphere reeking with traditions of insular supremacy, and nurtured from his youth up on notions of commercial arrogance, it is no miracle that he arrives at maturity with singularly inflated ideas of the greatness of his powers and person. If there is one thing more than another in which he feels particular pride it is the possession of a superabundant stock of what he is pleased to call “business acumen,” and to hear him, it might be imagined that no one could approach him in enterprise and general commercial ability.

In the good old days, before civilisation and artificial eating habits caught up with mankind, the majority of people in the world got all the Vitamin B and protein their bodies needed through micro‐organic foods. Before the discovery of tea and coffee as beverages, European man drank beer and ale, and the people of Africa, Asia and Australasia drank palm wines. These drinks were prepared by the use of micro‐organisms or fermentation, and supplied large quantities of high‐grade protein and Vitamin B, so essential for health and growth. With the discovery of food yeast and the proposed manufacture of this remarkable food in the British Colonies, the modern diet is going to be revolutionised. The manufacture of bakers' yeast is a simple process and has been known to man for hundreds of years. Into a certain weight of yeast is. introduced a solution of sugars, nitrogen and phosphates and this is allowed to multiply and grow until it has increased its weight fourfold. During this time air is pumped into the solution so the micro‐organisms can breathe, and at the end of nine hours the yeast in the vat is separated from the bulk of the used food solution, washed and pressed ready for use. Yeast has become in recent years increasingly popular as a food, and research workers, knowing the value of yeast in the diet to correct deficiencies, have not been idle in this field. For many years Dr. A. G. Thaysen, Ph.D., M.Sc., has been conducting experiments with yeast, and now, under the auspices of the Colonial Products Research Council, the Department of Scientific and Industrial Research is setting up a Micro‐biological Research Laboratory to carry out further experiments. As a result of visits to the West Indies by Sir R. Robinson and Professor Simonsen, it has been decided that this laboratory should be built in St. Clair, Port of Spain, where Dr. Thaysen will conduct experiments for an initial period of three years. Dr. Thaysen is of Danish origin, a naturalised British subject. He went to England early in 1914 to work at the Lister Institute on micro‐organisms, and when World War I. broke out the Admiralty secured his services for special war work. After the war he continued his research work with the Admiralty, and in 1936 his laboratory was transferred to the Department of Scientific and Industrial Research. Recently the Colonial Products Research Council, by arrangement with the Department of Scientific and Industrial Research, secured Dr. Thaysen's services for the study of food yeast in the West Indies. Whereas bakers' yeast will only increase fourfold in nine hours, it has been possible to increase the weight of food yeast 64‐fold in the same time, and this yeast shows the same behaviour in its life cycle as is characteristic of all free living bacteria. The aim of these experiments is the manufacture of food yeast on an industrial scale, and some years ago a small pilot plant was started at Teddington, England, where some 100 to 150 lb. of food yeast could be produced weekly. With the experience gained at this plant, the Colonial Office has set up a commercial scale plant in Jamaica with funds provided under the Colonial Development and Welfare Act. Jamaica was chosen for the site of this first pilot plant in the West Indies because the West Indies Sugar Company had the available accommodation, surplus power and technical staff to manufacture food yeast economically, and also had adequate supplies of molasses, sugar and cane juice close at hand. A similar plant is under construction in India. In planning for a wide scale manufacture of food yeast it is necessary to select localities where there is an abundant and cheap supply of the necessary sugars or other carbohydrates. The West Indies and India, for instance, can supply molasses; Africa, maize and other grains; the Middle East, citrus fruit and carob beans; and Canada, Newfoundland and the United States, waste sulphite liquor from the manufacture of paper. Food yeast, as produced in the pilot plant, is a light, straw‐coloured flaky powder with a pleasant nutty or meaty flavour. It has a protein content of between 40 and 45 per cent., contains some 2 per cent. of phosphorus, a balanced proportion of Vitamin B, riboflavin and nicotinic acid, and is superior to liver and the various yeast extracts at present on the market. One ton of food yeast can be produced from 1·7 tons of sugar products or other carbohydrates. Food yeast has been fed successfully to livestock with remarkable results, and for human consumption it can be incorporated into flour for bread and biscuits and used for flavouring soups and stews. To quote Dr. Thaysen : “ It is essential to produce food yeast at the lowest possible price if it is to serve its primary purpose of supplying those sections of humanity who are least blessed with worldly riches with a wholesome and abundant protein and Vitamin B food.” In other words, it can well be seen that the discovery of food yeast is going to be one of the greatest contributions science has made in our own time, the atomic bomb notwithstanding, and with so many people in the world at the moment suffering from years of malnutrition in varying degrees, food yeast is going to be one of the Allied Nations' greatest contributions to the rehabilitation of the world and the immediate need to feed Europe, after years of war, can be faced confidently now that Jamaica is producing it in sufficient quantity.

This paper seeks to examine the export competitiveness and concentration level of the 15 top sugar exporting countries over the last 18 years (2001–2018) with special reference to India.

First, the paper utilizes a review based approach and explains the structures of major sugar economies in context to protected and unprotected perspectives. Subsequently, empirical research was carried out to assess the competitiveness level of sugar using Revealed Comparative Advantage (RCA) approach and Hirschman Herfindahl Index.

The study found structural changes in cane or beet sugar, and molasses over the time period between 2006 and 2015. Further, the findings confirmed that despite the stringent regulations in European Union, the United States of America, Guatemala, Mexico, Thailand, China, and India, the comparative advantage is high up to seven to nine sugar categories. Besides, despite the indulgent regulations in the Colombia, Brazil, and Canada, the comparative advantage is only consistent up to two to three sugar categories.

This study provides an overview of competitiveness patterns of 15 sugar exporting countries and further compare their comparative and concentration levels. In this context, in future, it would be interesting to study the macro-economic and firm and industry-specific factors which may strengthen the study findings.

This study suggests that the sugar export of few countries (i.e. Mexico and Canada) is restricted up to their trade pacts and free trade zones which is restricting the competitiveness level and performance. Accordingly, such countries need to enlarge their business boundaries to foster their export competitiveness level. Rational subsidies and governmental assistance in diversification schemes in terms of products' range and sustainable processes can make India a consistent exporter in more categories.

Although, the previous studies attempted to examine the sugar industry with particular country context, this study enlarge the body of knowledge through simultaneously examining the sugar export scenario of fifteen sugar exporting countries and providing a broad comparative view of their competitiveness and concentration levels.
