Abstract Ensuring profitability is top priority when considering whether to purchase a new piece of equipment. However, whether a furnace purchase will add value is a difficult question to answer. Between complex heat treatment cycles and varying utility consumption, the number of variables that contribute to a value statement can be overwhelming. For heat treaters, this can make it difficult to know what to charge for services to stay competitive and still hit target break-even timelines. The design of the equipment itself can have a dramatic impact on operating cost, which further increases complexity. Using a systematic approach to evaluate purchase decision can protect payback periods and recover value that is lost using more common simplified approaches.

This research studied the commercial exploitation of an indigenous African crop in order to formulate high value products, with a potential significant impact on the local economy. More specifically, the present work investigated the extraction of polysaccharides from baobab in a bench-scale unit, focusing on the overall yield and the techno-economic assessment of the extraction process. Preliminary technoeconomic analysis for two scenarios (with and without ethanol recycling) was performed to determine the economic viability of the process and the development of the baobab market both in Nigeria and the UK. A full economic analysis was undertaken for each of the two scenarios, considering all operating and capital costs, and the production cost of baobab polysaccharides was estimated based on a constant return on investment. Combining the operating cost with the average polysaccharide yield, the minimum profitable selling price in the UK was estimated to be between £23 and £35 per 100 g of polysaccharide, which is comparable to the commercial selling price of high purity polysaccharides. An assessment of a scaled-up plant was also performed under Nigerian conditions and the results showed that such an investment is potentially viable and profitable, with a minimum profitable selling price of £27 per 100 g, a value comparable to the UK-based scenarios.

This article studies the possibility of intensification of Kharanorskoe deposit brown coal alkaline activation by way of electromagnetic microwave radiation (EMR) exposure in order to obtain sorbents. There is data that presents investigation of qualitative and adsorption properties of sorbents obtained from 0-2 mm brown coal samples impregnated with potassium hydroxide at a KOH / coal of 1 g / g weight ratio and subjected to thermolysis at 800 °C in the thermal shock mode. The authors carried out a detailed analysis of three options for thermal treatment of the coal-alkali mixture ahead of thermolysis: coalalkali mixture drying to indiscrete mass, EMR treatment and combination of ones. The design of a laboratory microwave oven for heat treatment of raw materials based on the use of EMR at a frequency of 2,450 MHz is presented. It was found out that the effect of electromagnetic microwave radiation with a frequency of 2.450 MHz makes it possible to increase the adsorption activity on iodine by 4-6%, reaching a value of 97%, to significantly shorten the time of preliminary heat treatment of the coalalkali mixture and to shorten the thermolysis time when sorbents obtain.

The Subject

Why certain Irishmen came to use violence to obtain their political objectives during the Anglo-Irish War of 1919–21 has proved a difficult question. A number of local studies of the experience of volunteers, following the example of David Fitzpatrick, have provided insights into the process of radicalisation but have not dealt with this aspect of the subject explicitly. A more systematic approach has been taken in the attempt to explain the strong variations in the intensity of activity throughout the country. What caused these variations has indeed been a matter of contention ever since the Anglo-Irish War itself. Michael Collins often voiced complaints about ‘slack’ areas in language that left little to the imagination. Since the publication of Erhard Rumpf’sNationalismus und Sozialismus in Irlandin 1959 historians have sought to explain the unequal distribution of violence by comparing the level of I.R.A. activity in a particular county with certain geographically distributed social and economic variables. Hitherto these attempts have been unable to produce a full explanation for regional variations.

The application of food processes can lead to a modification of both the structure and the activities of flavonoids. In this article, the effect of heat treatment and exposure to light on the antioxidant activity of 6 model flavonoid solutions (rutin, naringin, eriodictyol, mesquitol, luteolin, and luteolin 7-O-glucoside) was studied. The evolution of the antioxidant activity measured after heat treatment of 130 °C at 2 h and an exposure to visible light for 2 weeks is measured by the ABTS (2,2′-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt) method and represented by a new parameter called ΔTEAC. The model solution of Mesquitol showed the highest increase in ΔTEAC after a heat treatment, a value of 200 mM was obtained. The increase in ΔTEAC is always greater with thermal treatment than with light exposure. Thus, temperature and light lead to different degradation pathways of the flavonoid. In vivo measurements were carried out with solutions of naringin, erodictyol, and luteolin 7-O-glucoside. Heated solutions of flavonoids do not exhibit toxicity on cells. The specific activities of superoxide dismutase and glutathione peroxide have been determined and have shown an increased impact on the potential anti-cancer of these solutions by enhancing their cellular antioxidant activity, as well as modulation of the oxidative stress.
