Improved yield and biological efficiency (BE) of Pleurotus eryngii var. eryngii were achieved by supplementation of substrate with a commercial delayed-release nutrient and use of a casing overlay. Yield increases of 14% were achieved from cased substrates that were supplemented at time of casing with delayed-release nutrient (Remo's). Use of a casing layer enhanced yield by 141% over non-cased...

In this study, the possibility of using tea production waste as a new casing material in mushroom (Agaricus bisporus) cultivation was investigated. Some physical and chemical characteristics of tea waste, fermented tea waste and a mixture of tea waste with peat were compared with that of peat casing, as were their effects on yield. The highest yield was obtained from peat casing. Using tea prod...

to reduce peat while increasing the water holding capacity (whc) of casing soil in button mushroom production an experiment was conducted in 2006 with three hydrogel treatments of: t0= casing soil with no hydrogel, as control, t1= casing soil + 10% hydrogel (v/v), and t2= casing soil + 20% hydrogel (v/v) with three replicates in a completely randomized design. results indicated that treatment 1...

The internal pressure strength of tubing and casing often cannot satisfy the design requirements in high pressure, high temperature and high H2S gas wells. Also, the practical safety coefficient of some wells is lower than the design standard according to the current API 5C3 standard, which brings some perplexity to the design. The ISO 10400: 2007 provides the model which can calculate the burs...

Calocybe indica, a tropical edible mushroom, is popular because it has good nutritive value and it can be cultivated commercially. The current investigation was undertaken to determine a suitable substrate and the appropriate thickness of casing materials for the cultivation of C. indica. Optimum mycelial growth was observed in coconut coir substrate. Primordia initiation with the different sub...

Various bacteria were isolated from the casing layer soil of the culture bed of P. ostreatus and their role in fruiting body induction of the edible mushroom, P. ostreatus, was investigated. Analysis of the bacterial community isolated from the casing layer soil revealed that the composition of genera and number of cultivable bacteria were different for each sterilizing treatment. Bordetella wa...

This research paper presents numerical studies of the characteristics of warhead fragmentation in terms of initial velocities, spray angles of fragments and fragment mass distribution of high explosive (HE) warhead. The behavior of warhead fragmentation depends on shape and size of warhead, thickness of casing, type of explosive, number and position of detonator, and etc. This paper focuses on ...

Supplementation of mushroom compost at spawning and at casing with various refined and crude seed oils resulted in 1 to 1.5 lb/ft increases in mushroom yield. Supplementation at casing with ground seeds or protein-oil combinations caused 2 to 2.5 lb/ft increases in mushroom yield. Further evidence is presented for a relationship between lipid metabolism and the initiation of fruiting in the cul...

in this study, the recovery of casing soil consumed in the white button mushroom was investigated. casing soil is used as a layer on compost (culture medium) to a diameter of 3-5to stimulate fruiting on the white button mushroom(agaricus bisporus) . the expense od casing soil is about 30 percent of production costs. in the first step of this experiment, in order to separate casing soil from com...

When the thermal stresses induced in a geothermal well’s casing string exceed the yield strength of the casing material, the fatigue behavior of the latter can be defined as low cycle fatigue (LCF). The connection threads in the casing body amplify the local stress distribution and lower LCF resistance. A theoretical approach is presented to evaluate LCF resistance and compared with preliminary...
