Utilization of Ceramic Beads for Edible Mushrooms Cultivation

In recent years, mushrooms have been drawing much public attention as a source of development for medications and nutraceuticals because of their antioxidants, antitumors, and antimicrobial properties. And they are also becoming more essential to the human diet due to their nutritional value, high levels of protein and low levels of fat. Besides, for mushrooms can be cultivated with low cost and low usage of land compared to other agricultural products, many farmers and manufacturers are turning towards the cultivation of mushrooms.

In this study, the authors examined ceramic beads as a reusable material for cultivation of edible mushrooms. And 20 species of edible mushrooms were tested, which were obtained from the Mushpia Co. Limit., Fukuoka, Japan. Within the cultivation vessels, 70% were ceramic beads (diameter 1 cm) and 30% of the nutrient solution. Moreover, the control groups used several types of sawdust, wheat bran, and rice bran with the ratio of 8:1:1 as the substrate. Two sets of substrates were evaluated with the fruit bodies yield. And Identification of statistical differences within treatments was done by Analysis of Variance (ANOVA), followed by Tukey’s post hoc test. All the analyses were done with 0.05 significance levels.

The result indicated that there were 11 species that responded well with the ceramic bead substrate when compared to the traditional sawdust substrate with Agrocybe cylindrica and Pleurotus ostreatus performed the best adding 70 g more of the fruit bodies. Conversely, nine species responded poorly with the ceramic beads substrate with Auricularia polytricha performed the worst losing 120 g.

In conclusion, ceramic beads as a reusable material for substrates not only provide a clean and controllable environment for mycelium to colonize, but also deliver more aeration and water availability inside the cultivation vessels. And the application of the ceramic bead cultivation can be viewed as an alternative solution for producing Ophiocordyceps sinensis on the industrial level.

Electron Spin and Proton Spin in the Hydrogen and Hydrogen-Like Atomic Systems

Read full paper at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=52202#.VIj7tMnQrzE Author(s) Stanisław Olszewski * Affiliation(s) Institute of Physical Chemistry, Polish Academy of Sciences, Warsaw, Poland . ABSTRACT The mechanical angular momentum and magnetic moment of the electron and proton spin have been calculated semiclassically with the aid of the uncertainty principle for energy and time. The spin effects of both kinds of the elementary particles can be expressed in terms of similar formulae. The quantization of the spin motion has been done on the basis of the old quantum theory. It gives a quantum number n = 1/2 as the index of the spin state acceptable for both the electron and proton ...

Remarks on the Complexity of Signed k-Domination on Graphs

Read  full  paper  at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=53574#.VMnXsCzQrzE Author(s)    Chuan-Min Lee 1 , Cheng-Chien Lo 1 , Rui-Xin Ye 2 , Xun Xu 2 , Xiao-Han Shi 2 , Jia-Ying Li 2 Affiliation(s) 1 Department of Computer and Communication Engineering, Ming Chuan University, The First American University in Asia, Taoyuan, Taiwan, Chinese Taipei . 2 Department of Electronic Information Engineering, Fuzhou University, Fuzhou, China . ABSTRACT This paper is motivated by the concept of the signed k-domination problem and dedicated to the complexity of the problem on graphs. For any fixed nonnegative integer k, we show that the signed k-domination problem is NP-complete for doubly chordal graphs. For strongly chordal graphs and distance-hereditary graphs, we show that the signed k-domination problem can be solved in polynomial time. We also show that the problem is linear-time solvable for trees, interval graphs, and chord...
