This paper aims to investigate the physical, chemical and physicochemical characteristics of rice husk on alkaline treatment.

Rice husk (RM) was alkaline treated to produce soluble (SR) and insoluble residues (IR). Each fraction was characterized and soluble fraction was used to produce nanofibres using electrospinning method.

Alkaline treatment was effective in isolating insoluble dietary fibre rich IR from the other interfering substances such as soluble dietary fibre, protein and lipids that originally present in RM and leached into SR. The problem of silica induced toxicity and indigestibility of rice husk was overcome by alkaline treatment. Alkaline treatment altered the inherent mineral content (calcium, copper, iron, potassium, magnesium, manganese, sodium, phosphorus, zinc) of rice husk, and increased physicochemical properties such as emulsification ability and stability, water holding ability, mineral binding capacity (calcium, copper, iron, zinc), and antioxidant activity. SR had been successfully electrospun into nanofibres with the addition of polyvinyl alcohol.

The paper investigated the characteristic of rice husk (RM and IR) for the development of functional foods, pharmaceutical products and new bioactives delivery system at the expense of reducing environmental liability.

The change in climate and depletion of natural resources because of the harmful emissions from different materials becomes a main issue for the globe. Some of the developed and developing countries have focused on this issue and performed research to provide a solution. The purpose of this study is to identify the best types of concrete based on its impact on the environment and economy.

The life cycle assessment and life cycle cost analysis of six concrete mixtures that include construction and demolition wastes (CDW), marble sludge, rice husk and bagasse ash as a partial replacement of cement, are performed. These types of concrete are compared with each other and with ordinary concrete to select the best possible concrete type for a developing country, like Pakistan.

The results show that, although for an agricultural country like Pakistan, the agriculture wastes such as rice husk and bagasse ash are preferable to be used, if the emissions of CO₂ and CO from rice husk and NOx and SO₂ from bagasse ash are properly controlled. However, based on the results, it is recommended to use the CDW in concrete because of the small amount of air emissions and affordable prices.

Through this study, a path has been provided to construction companies and relative government organizations of Pakistan, which leads to sustainable practices in the construction industry. Moreover, the base is provided for future researchers who want to work in this area, as for Pakistan, there is no database available that helps to identify the impact of different concrete on the environment.

Husk Power Systems, a young but widely celebrated firm based in India, needs $1.5 million to $2.5 million of expansion capital to grow quickly beyond the small footprint it had established in northeast India. It was a successful green-energy enterprise that aimed to provide electricity to millions of rural Indians in a financially viable way. With 10 “mini power plants” that used rice husks as a fuel source and a presence in 25 isolated Indian villages as of April 2009, the company's goal was to reach 350,000 to 400,000 consumers in 400 villages by the end of 2011. It was offered a convertible-note financing structure by a cleantech private equity firm and needed to assess whether it suited the company's and founders' interests.

This case was designed for and is used in Darden's Entrepreneurial Finance and Private Equity elective. With less of a focus on the financials, the Husk case has also been used in other Darden courses such as Social Entrepreneurship and Global Economies and Markets in a module focusing on emerging markets.

Merchants and manufacturers have it in their power to minimise in some degree the extent to which we are becoming indebted to foreign countries in respect of the large excess of imports over exports, by obtaining, as far as possible, their imported supplies of food products and raw materials for industries from countries within the Empire. Take, for example, meat and cheese. The prevailing high prices are no doubt encouraging the home production of these commodities. Nevertheless a large quantity must necessarily be imported. In 1914 meat to the value of 62 million pounds was imported, and cheese to the value of 8 million pounds. Of the imports of meat 26 per cent. came from within the Empire, and of cheese 82 per cent. Clearly it is better under existing circumstances that we should buy meat from Australia and New Zealand than from Argentina, and cheese from Canada and New Zealand rather than from Holland and the United States. Many other examples may be mentioned of products which can equally as well be obtained within the Empire as from foreign countries, such as maize from South Africa, where a large increase of production is expected this year; oats from Canada rather than from Argentina and the United States; barley from Canada; peas from New Zealand; butter from Australia and New Zealand; canned salmon, of which 2½ million pounds' worth was imported in 1914, from Canada rather than from the United States; apples from Canada and Australia; wine from Australia; tea from India and Ceylon rather than from China and Java; cocoa from the Gold Coast and the West Indies; copra from Malaya, India and Australia; rubber from Malaya and Ceylon; fibres from New Zealand, Mauritius, Ceylon, etc.; wood pulp from Canada and Newfoundland; wool from Australia, New Zealand, South Africa and the Falkland Islands rather than from Argentina, Chile and other foreign sources; tanning materials from India, Natal, Australia and British East Africa; dyewoods from the West Indies; timber from Canada; hardwoods from India, West Africa, the West Indies and Australia; copper and copper ore from Australia and South Africa; tin and tin ore from Malaya, Nigeria, South Africa and Australia; manganese from India; plumbago from Ceylon; hides from India, Africa and Australia, and so forth. It has been stated that the result of the war may ultimately depend largely on financial strength. In that case the country which is to the greatest extent self‐supporting as regards supplies of the necessaries of life and materials for the manufacture of munitions of war will be in a position to carry on the longest. Undoubtedly the British Empire contains within itself the power to produce all such materials, and the Dominions, Colonies and Dependencies are in fact already supplying a large proportion of the food products and raw materials for industries, which are imported into the United Kingdom. There are a few notable exceptions, e.g., for our supplies of cotton and sugar we have always been largely dependent on foreign countries, but Uganda and the Soudan are capable of producing in the future very large quantities of cotton of the quality required by Lancashire spinners, and sugar production in our Colonies could, with proper encouragement, be expanded so as to meet the whole of the requirements of the Mother Country. If the British capital and energy which have in the past gone every year to the development of enterprises in foreign countries had been devoted for a tew years exclusively to exploiting the resources of the Dominions and Colonies, the British Empire would, by this time, have become practically self‐supporting, and the bulk of our imported foodstuffs and raw products required for our manufacturing industries would now be obtained from within the Empire and paid for by increased quantities of our own manufactures. It may be hoped that one of the lessons which we shall learn from the war will be definitely to encourage the development of the vast resources of our overseas Empire. — The Chamber of Commerce Journal.

The purpose of this paper is to study Al-based green composite. To make composite samples of aluminium alloy (AA3105) with different weight percentages of rice husk ash (RHA) and eggshell (ES) particles as reinforcement, stir casting method was used.

Several other aspects, including the weight percent of reinforcing agent particles, the applied stress and the sliding speed, were taken into consideration. During the course of the wear test, the sliding distance that was recorded varied from a minimum of 1,000 m all the way up to a maximum of 3,135 m (10, 15, 20, 25 and 30 min). The typical range for normal loads is 8–24 N, and their speed is 1.58 m/s.

With the AA/ES/RHA composite, the wear rates decreases when the grain size of the reinforcing particles enhanced. Scanning electron microscopy images of worn surfaces show that at low speeds, delaminating and ploughing are the main causes of wear. At high speeds, ploughing is major cause of wear. Composites with better wear-resistant properties can be used in wide range of tribological applications, especially in the automotive industry. It was found that hardness increases at the same time as the weight of the reinforcement increases. Tensile and hardness were maximized at 10% reinforcement mix in Al3105.

In this work, ES and RHA has been used to develop green metal matrix composite to support green revolution as promoted/suggested by United Nations thus reducing the environmental pollution.

In the second part of this report the action of nitrogen peroxide on flour is discussed at some length in an account of a series of researches that have been carried out by DR. MONIER‐WILLIAMS. His conclusions may be briefly stated as follows. The maximum bleaching effect is obtained when each kilogram of flour is treated with from 30 to 100 cubic centimetres of nitrogen peroxide. The bleaching effect becomes more pronounced after keeping for several days. The amount of nitrous acid or nitrites that are present in bleached flour corresponds to about 30 per cent. of the total nitrogen absorbed, the proportion of nitrites present remaining nearly constant after the lapse of several days in the more slightly bleached samples. After the lapse of a short time it is still possible to extract about 60 per cent. of the nitrogen absorbed by the flour by means of cold water, but after several days the nitrogen that can be extracted by this means decreases. This may perhaps be attributed to the “absorption” of nitrous acid by the glutenin and gliadin. In highly bleached flour (300 cubic centimetres of nitrogen peroxide per kilogram of flour) a considerable increase in the amounts of soluble proteins and soluble carbohydrates takes place. In highly bleached flour, after some time, about 6 or 7 per cent. of the nitrogen introduced as nitrogen by the nitrogen peroxide is absorbed by the oil, which acquires the characteristics of an oxidised oil. No evidence is forthcoming as to the formation of diazo compounds nor the production of free nitrogen. Bleaching was found to exercise an inhibitory action on the salivary digestion of flour.

A geographically proximate group of rice mills, supporting companies, suppliers, and associated institutions in a particular field is emerging as a concept to make rice mills more competitive. The factors, which emerged due to cluster formation, appear to have the potential to contribute to the performance of rice mills. The purpose of this paper is to investigate the effect of a rice mill cluster initiative. The primary objective is to identify the critical factors of a successful rice mill cluster initiative. To meet this objective, a questionnaire is developed for the assessment of effects of cluster elements.

The methodology used for this paper is an exploratory cross‐sectional and literature review of published materials.

There is strong evidence to suggest that a cluster policy brings additional positive effect to existing small enterprises such as rice mills located in a cluster.

This study offers initial empirical evidence and a number of important insights to assist managers and policy makers in enhancing performance of rice mills located in a cluster. The findings from this research will assist strategy makers in making more informed decisions regarding the adoption of a cluster approach and entering into cluster‐based relations, as well as assisting policy makers in designing more efficient cluster policies. The academic value will be added in the context of expanding knowledge in relation to the impact of clusters on economic development in developing countries and as such contribute in filling gaps within the existing literature.

The action taken by the Council of the British Medical Association in promoting a Bill to reconstitute the Local Government Board will, it is to be hoped, receive the strong support of public authorities and of all who are in any way interested in the efficient administration of the laws which, directly or indirectly, have a bearing on the health and general well‐being of the people. In the memorandum which precedes the draft of the Bill in question it is pointed out that the present “Board” is not, and probably never was, intended to be a working body for the despatch of business, that it is believed never to have met that the work of this department of State is growing in variety and importance, and that such work can only be satisfactorily transacted with the aid of persons possessing high professional qualifications, who, instead of being, as at present, merely the servants of the “Board” tendering advice only on invitation, would be able to initiate action in any direction deemed desirable. The British Medical Association have approached the matter from a medical point of view—as might naturally have been expected—and this course of action makes a somewhat weak plank in the platform of the reformers. The fourth clause of the draft of the Bill proposes that there should be four “additional” members of the Board, and that, of such additional members, one should be a barrister or solicitor, one a qualified medical officer of health, one a member of the Institution of Civil Engineers, and one a person experienced in the administration of the Poor‐law Acts. The work of the Local Government Board, however, is not confined to dealing with medical, engineering, and Poor‐law questions, and the presence of one or more fully‐qualified scientific experts would be absolutely necessary to secure the efficient administration of the food laws and the proper and adequate consideration of matters relating to water supply and sewage disposal. The popular notion still exists that the “doctor” is a universal scientific genius, and that, as the possessor of scientific knowledge and acumen, the next best article is the proprietor of the shop in the window of which are exhibited some three or four bottles of brilliantly‐coloured liquids inscribed with mysterious symbols. The influence of these popular ideas is to be seen in the tendency often exhibited by public authorities and even occasionally by the legislature and by Government departments to expect and call upon medical men to perform duties which neither by training nor by experience they are qualified to undertake. Medical Officers of Health of standing, and medical men of intelligence and repute are the last persons to wish to arrogate to themselves the possession of universal knowledge and capacity, and it is unfair and ridiculous to thrust work upon them which can only be properly carried out by specialists. If the Local Government Board is to be reconstituted and made a thing of life—and in the public interest it is urgently necessary that this should be done—the new department should comprise experts of the first rank in all the branches of science from which the knowledge essential for efficient administration can be drawn.

Although the crucial role of business, and of business‐based approaches, in development is increasingly emphasised by academics and practitioners, insight is lacking into the “whether and how” of viable business models, in environmental, social and economical terms. This article analyses private‐sector involvement in development, including a business perspective of firm‐level factors, taking the case of sustainable energy in developing countries.

In the framework of the international business and development debate, the authors examine the “state of the art” on sustainable energy and business involvement, and present their own research on illustrative cases from local companies involved in renewable, off‐grid rural electrification. Implications are discussed, as viewed from the broader perspective of business models.

Existing studies on sustainable energy take macro‐economic and/or policy‐oriented approaches, containing specific case studies of rural electrification and/or recommended financing/delivery models. The authors categorize them on two dimensions (levels of subsidies and public/private involvement) and conclude that market‐based models operating without subsidies hardly exist in theory – and also not in practice, as the study shows that companies can at best have part of their portfolio non‐subsidized based on customer segmentation or require socially oriented investors/funders.

This exploratory study can be a starting point for further in‐depth analyses.

The article outlines challenges faced by companies/entrepreneurs when aiming for viable business models, and provides insights to policy‐makers who want to further the role of business in sustainable (energy) development.

Sustainable energy and development are crucial and interlinked issues highly relevant to global society, as exemplified by the UN year of Sustainable Energy for All and Rio+20.

The article contributes new dimensions and perspectives that have been left unexplored, and that are crucial for reducing poverty and stimulating sustainable (energy) development.

To describe water absorption by the rice grains over time, diffusion and empirical models were used. Also, an optimization software was developed in this study to determine parameters and their uncertainties for the diffusion models (LS Optimizer, for partial differential equations). Parameters (and their uncertainties) for empirical models were determined by LAB Fit Curve Fitting Software.

Heat and mass diffusion phenomena are found in various processes of technological interest, including pasteurization, drying and water immersion of agricultural products, among others. The objective of this work was to study the process of water absorption by rice grains with and without husk, using diffusion and empirical models to describe the absorption kinetics. Rice grains were immersed (approximately 10 g for each experiment) in drinking water maintained at constant temperatures of 28, 40 and 50 C. In the experiments, the water contents absorbed by rice grains over time were obtained by the gravimetric method.

Among empirical models, Peleg was the most satisfactory to describe the kinetics of water absorption by rice without husk, while the Silva et alii model had the best statistical indicators for rice with husk. It was also verified that a diffusion model with boundary condition of the first kind showed the best (or equivalent) results in the description of all processes of kinetics of water absorption by rice grains, with and without husk. For grains without husk, the effective mass diffusivities were (1.186 ± 0.045) × 10⁻⁹, (1.312 ± 0.024) × 10⁻⁹ and (2.133 ± 0.028) × 10⁻⁹ m² min⁻¹, for the immersion temperatures of 28, 40 and 50C, respectively. For grains with husk, diffusivities were (0.675 ± 0.011) × 10⁻⁹ and (1.269 ± 0.017) × 10⁻⁹ m² min⁻¹, for temperatures of 28 and 50 C, respectively.

This work developed a solver for the diffusion equation in cylindrical geometry and presented the LS Optimizer software developed to determine differential equation parameters through experimental data sets.
