THE EFFECTS OF TEMPERATURE AND MOISTURE STRESS CONTENT ON THE EXTENSIVE CULTIVATION OF THE OYSTER MUSHROOM
...Show More Authors

    Oyster mushroom (Pleurotus ostreatus (Jacq. ex Fr.) P. Kumm.) is involved in the destruction of dead wood which is the main place of settlement of several living organisms. After humification, dead wood also becomes an important component of forest soils.

 

    The purpose of the research is to study temperature and moisture conditions of extensive cultivation of oyster mushrooms on various wood substrates. To accomplish this goal, the following tasks were set: to determine the amount of effective stress temperatures and moisture content of substrates and their influence on the appearance of fruiting bodies of the oyster mushroom; to study the features of the extensive cultivation of oyster mushrooms on the tree stumps of cutover areas, in the hollows of broadleaved trees, using brushwood, on inoculated log sections in trenches, on log sections of dead dry trees. The oyster mushroom fruiting bodies collected in the suburban forest formed the basis of the experiment on the inoculation of different types of substrates. The inoculation of the log sections was carried with a relative air humidity of 85%, the process of overgrowing lasted from 2 to 3 months. The edaphic-climatic factors of different types of space - closed and open - were taken into account.

 

    The amount of effective temperatures necessary for the development of fruiting bodies has been determined. It was found that the intensive growth of the mushroom fruiting bodies begins after a sharp cooling (a drop in night temperatures to 4-8 ° C), which causes a stressful state of the mushroom. The amount of the effective stress temperatures is 4.6 ° C. Long-term phenological observations have revealed that the amount of the effective temperatures in the spring is 76.4 ° C, and in the autumn - 59.4 ° C. The duration of fruiting of oyster mushroom on log sections of hardwoods is 14 days in spring and 17 days in autumn longer than on softwoods blocks. It was found that the biomass of the fruiting bodies is directly dependent on the thickness of the log section, and, therefore, it is recommended to use log sections ranging from 35 cm to 50 cm in diameter and up to 30 cm in length.

The Effect of Using an Accounting Information System Based on Artificial Intelligence in Detecting Earnings Management to Enhance the Sustainability of Economic Units
...Show More Authors

This research aims to clarify the importance of an accounting information system that uses artificial intelligence to detect earnings manipulation. The research problem stems from the widespread manipulation of earning in economic entities, especially at the local level, exacerbated by the high financial and administrative corruption rates in Iraq due to fraudulent accounting practices. Since earning manipulation involves intentional fraudulent acts, it is necessary to implement preventive measures to detect and deter such practices. The main hypothesis of the research assumes that an accounting information system based on artificial intelligence cannot effectively detect the manipulation of profits in Iraqi economic entities.

Experimental Study on the Impact of External Geometrical Shape on Free and Forced Convection Time Dependent Average Heat Transfer Coefficient during Cooling Process
...Show More Authors

In this research, an experimental study was conducted to high light the impact of the exterior shape of a cylindrical body on the forced and free convection heat transfer coefficients when the body is hold in the entrance of an air duct. The impact of changing the body location within the air duct and the air speed are also demonstrated. The cylinders were manufactured with circular, triangular and square sections of copper for its high thermal conductivity with appropriate dimensions, while maintaining the surface area of all shapes to be the same. Each cylinder was heated to a certain temperature and put inside the duct at certain locations. The temperature of the cylinder was then monitored. The heat transfer coefficient were then cal
