Characterization of Biochar Produced from IRAQI Palm Fronds by Thermal Pyrolysis
...Show More Authors

Abstract

The present paper focuses in a particular on the study of the biochar production conditions by the thermal pyrolysis of biomass from local Iraqi palm fronds, in the absence of oxygen. The biochar product can be used as soil improvers. The effect of temperature on the extent of the thermal pyrolysis process was studied in the range from 523 to 773K with a residence time of 15 minutes and nitrogen gas flow rate of 0.1 l/min. The produced biochar was characterized as will as biomass and degradation products. The results showed that the rate of biochar production decreases with the increasing in temperature, also it was noted that the normalized biochar surface area and pore size increases with the increasing in temperature.

The results showed an increase in the biochar ability to absorb water and the percent of water content increases with increasing temperature. The quality and quantity of the products of the thermal pyrolysis of biomass depend directly on the temperature and on the biomass basic composition of the compounds: hemicellulose, cellulose and lignin.

FTIR analysis gave an excellent description to the nature of the active groups on the biochar surface. These groups vary with the temperature and biochar composition (i.e. hemicellulose, cellulose and  lignin).

Forgotten Iraqi poets
...Show More Authors

Through my acquaintance with the literature of Iraqi women, specifically during the first half of the twentieth century, I noticed a lack of interest in this type of literature, which forms part of our literary history. Therefore, I decided to date this literature and extract its output from the stomachs of newspapers and magazines, so that readers can see it and remember the names of the Iraqi poets who defied the difficulties in order to participate in the literary movement and who made their contributions in the field of literature.
The truth is that the forgotten poets of Iraq are many, and I mention them, for example, but not limited to, Wadi’a Al-Shabibi, Wadi’a Taha Najm, Fiyah Abu Qalam, and others. Ibtihaj Atta Amin, Sabi

From Personal Issues to National Concerns: A Study in E.M Forster’s Where Angels Fear to Tread & Howards End
...Show More Authors

            E.M. Forster (1879-1970) is one of the important novelists who dealt with the personal and social lives of the people in England during the early beginning of the twentieth century. During his literary career, he developed gradually his views about man and his position in society.

 In his first novel, Where Angels Fear to Tread (1902), the focus is laid on local and personal issues in the lives of the characters. It is limited to the relations between neighbours in small communities. Though the setting is shifted to Italy, Forster does not make full use of this shift to present cultural or racial conflicts; rather he limits his plot to the private tr

Iraq’s Societal Security after 2003: Challenges and Countering Strategies
...Show More Authors

Societal security is regarded as a basic need for human society through which the stability, progress and prosperity of the nation is measured. It is the guarantor of the safety of individuals and groups from various internal and external dangers, based on the protection of the three pillars: the individual, the family, and society. For decades, Iraq has witnessed the phenomenon of political instability, represented by its entry into several wars, starting with the 1948 war, leading up to the American war on Iraq in 2003. Then, those wars were followed by an era in which corruption and terrorism spread, and this, in turn, led to the fragmentation of the national will and the division of Iraqi public opinion regarding many regional and inte
