Oilseed Rape straw for Cultivation of Oyster Mushroom

Oyster mushroom [_Pleurotus ostreatus_ var. _sajor caju_ (Fr.) Singer] cultivation can play an important role in managing organic waste. It can be cultivated on a wide rang of substrates containing lignin and cellulose. Oyster mushroom was grown on five substrates: Rise straw (Oryza sativa L. var. Alikazemi), Rise straw + Oilseed Rape straw (Brassica napus var. Hyola 401) (75:25 dw /dw), Rise straw + Oilseed Rape straw (50:50 dw /dw), Rise straw + Oilseed Rape straw (25:75 dw /dw) and Oilseed Rape straw alone. Oilseed Rape straw alone and Rise straw + Oilseed Rape straw (25:75 dw /dw) were best for fruit body production of P. ostreatus. Time to fruiting for P. ostreatus was also shorter on Oilseed Rape straw. Protein content of the fruit bodies obtained from Oilseed Rape straw was higher than those from other substrates. Using Oilseed Rape straw as a substrate appears to be suitable for oyster mushroom production

Language Change in a Post-Creole, British Contact Setting: Non-Standard Ain’t Negation

The word ain't is used by speakers of all dialects and sociolects of English. Nonetheless, language critics view ain't as marking speakers as "lazy" or "stupid"; and the educated assume ain't is on its deathbed, used only in cliches. Everyone has an opinion about ain't. Even the grammar-checker in Microsoft Word flags every ain't with a red underscore. But why? Over the past 100 years, only a few articles and sections of books have reviewed the history of ain't or discussed it in dialect contexts. This first book-length collection specifically dedicated to this shibboleth provides a multifaceted analysis of ain't in the history and grammar of English; in English speech, writing, television, comics and other media; and in relation to the minds, attitudes, and usage of speakers and writers of English from a range of regions, ethnicities, social classes, and dialect communities. Most articles in the collection are accessible for the average educated speaker, while others are directed primarily at specialists in linguistic study-but with helpful explanations and footnotes to make these articles more approachable for the layperson. This collection of articles on ain't thus provides a broad audience with a rich understanding and appreciation of the history and life of this taboo word

ELIMINATION OF CADMIUM AND LEAD MIXTURE IN SOLUTION BY PRETREATED RICE STRAW AND HUSK

An experiment on the activity of pretreated rice straw and husk in eliminating heavy metals from solution has been conducted. The rice straw and husk were soaked in 3% NaOH solution, drained and then washed with demineralised water until the washing became neutral (the results were referred to as straw and husk). The pretreated rice straw and husk (straw and husk) were mixed (stirring and without stirring) separately with Cd and Pb solution in time series. It was found that Cd was adsorbed more than Pb and straw was more active than husk. On the other hand, the stirring process and time series did not give much effect on straw, while the activity of husk increased with the increase of time period

PhD synopsis: Quantifying and evaluating the risk posed to straw bale constructions from moisture

This paper provides a synopsis of the PhD thesis titled 'Quantifying and Evaluating the Risk Posed to Straw Bale Constructions From Moisture'. The thesis reviews the potential for straw bale construction to aid the construction industry in reducing carbon emissions whilst promoting social and environmental values, and decreasing the reliance on non-renewable resources. Straw is however susceptible to degradation, under certain conditions. The thesis reviews different monitoring devices and the interaction of moisture with straw and presents a three part model aimed at promoting confidence in the construction method

Straw biomass - potential raw material for ethanol production

Barley straw was found to be suitable raw material for ethanol production. Straw could be easily pre-treated with steam explosion, hydrolysed to monosaccharides and fermented to ethanol. The optimum harvesting times for bio-ethanol raw material are at grain maturity for barley straw. Potential raw material, barley harvested at full ear emergence, when straw is rich in soluble sugars, need further research

Potential bioethanol and biogas production using lignocellulosic biomass from winter rye, oilseed rape and faba bean

To meet the increasing need for bioenergy several raw materials have to be considered for the production of e.g. bioethanol and biogas.In this study, three lignocellulosic raw materials were studied, i.e. (1) winter rye straw (Secale cereale L), (2) oilseed rape straw (Brassica napus L.) and (3) faba bean straw (Viciafaba L.). Their composition with regard to cellulose, hemicellulose, lignin, extractives and ash was evaluated, as well as their potential as raw materials for ethanol and biogas production. The materials were pretreated by wet oxidation using parameters previously found to be optimal for pretreatment of corn stover (195 1C, 15 min, 2 g l_1 Na2CO3 and 12 bar oxygen). It was shown that pretreatment was necessary for ethanol production from all raw materials and gave increased biogas yield from winter rye straw. Neither biogas productivity nor yield from oilseed rape straw or faba bean straw was significantly affected by pretreatment. Ethanol was produced by the yeast Saccharomyces cerevisiae during simultaneous enzymatic hydrolysis of the solid material after wet oxidation with yields of 66%, 70% and 52% of theoretical for winter rye, oilseed rape and faba bean straw, respectively. Methane was produced with yields of 0.36, 0.42 and 0.44 l g_1 volatile solids for winter rye, oilseed rape and faba bean straw, respectively, without pretreatment of the materials. However, biogas productivity was low and it took over 50 days to reach the final yield. It could be concluded that all three materials are possible raw materials for either biogas or ethanol production; however, improvement of biogas productivity or ethanol yield is necessary before an economical process can be achieved. 2007 Elsevier Ltd.

Use of Aluminum-Foil and Oat-Straw Mulches for Controlling Aster Leafhopper, \u3ci\u3eMacrosteles Fascifrons\u3c/i\u3e (Homoptera: Cicadellidae), and Aster Yellows in Carrots.

Aluminum-foil and oat-straw mulches significantly (P \u3c 0.05) reduced aster leafhopper numbers on carrots compared to an untreated control and a malathion spray treatment during the first half of the growing season. The amount of reflected light was significantly higher in both aluminum-foil and oat-straw mulched plots compared to unmulched treatments. Mulch effectiveness decreased when the closing carrot canopy reduced surface area of reflective mulches and amount of reflected light The percentage of aster yellows-infected plants was significantly lower (P \u3c 0.05) in aluminum-foil and straw mulches and in the malathion spray plots compared to the untreated control. Results demonstrated that aluminum-foil and straw mulches gave control of aster leafhoppers and aster yellows in carrots equal to that of a conventional insecticide spray program

Effects of fat source and dietary sodium bicarbonate plus straw on the conjugated linoleic acid content of milk of dairy cows

The effects of fat source (0.7 kg of fatty acids from extruded soybeans or palmitic acid), of sodium bicarbonate (0.3 kg) plus straw (1 kg) and the interaction of these treatments on the content of conjugated linoleic acid (CLA) in the milk of dairy cows were examined. During nine weeks a group of 10 cows received a ration with palmitic acid and bicarbonate plus straw (ration PAB). During three periods of three weeks a second group of 10 cows received successively a ration with extruded soybeans and bicarbonate plus straw (ration ESB), a ration with palmitic acid without bicarbonate or straw (ration PA), and a ration with extruded soybeans without bicarbonate or straw (ration ES). Rations ES and ESB increased the content of polyunsaturated fatty acids in milk, but decreased milk fat content, compared to rations PAB and PA. Ration ESB led to the greatest milk CLA content, by a synergy between the high amount of dietary fat, and the action of bicarbonate plus straw, favouring trans11 isomers of CLA and C18:1, presumably via a ruminal pH near neutrality. Ration ES favoured trans10 isomers, not desaturated in the mammary gland, so that the milk CLA content was lower than with ration ESB, and resulted in the lowest milk fat content. In conclusion, a ration supplemented with both extruded soybeans and bicarbonate plus straw, was an efficient way to increase the CLA content in the milk of dairy cows
