The current study dealt with anatomical aspects of species Iresine herbstii Hook.ex Lindl. which is the only species resemble the genus Iresine P.Br in Iraq . This species is considered as a new record in Iraq as it wasn’t mentioned within any resource of Iraqi plants. The study included anatomical characteristics of different parts of plants which are root, stem, petiole leaf and sepals. Also the type of venation was investigated , the shape and of seed Surface configuration . The results of the mentioned study of the parts as having important anatomical characteristics for the transvers and vertical sections in them, it also included a study of their tissues, where the root and stem sections appeared as circular, whereas petiole section

According to the circumstances experienced by our country which led to Occurrence of many crises that are the most important crisis is gaining fuel therefore, the theory of queue (waiting line) had been used to solve this crisis and as the relevance of this issue indirect and essential role in daily life.

Deep convective clouds tend to exert large but compensating effects in the shortwave and longwave that largely cancel, leading to a muted effect on net cloud radiative effect. Multi-layered cloud systems, ubiquitous in both hemispheres, exert strong cooling influence on Earth of around 6.1 W m-2.

Air pollution is considered one of the major environmental problems that contain many challenges and difficulties facing most countries of the world, including Iraq. The problem has emerged widely with the emergence of the industrial revolution in the world and the tremendous increase in the population and the increase in the number of transportation and its development in addition to excavation, maintenance and work Construction and weather fluctuations, such as dust and sandstorms, pollution resulting from oil refining, extraction, diversion and other processes that cause pollution, and the start of the world using methods that limit the volume of environmental pollution. The most prominent of these methods is the imposition of

The present study investigated the impact of fuel kind on the emitted emissions at the idling period. Three types of available fuels in Iraq were tested. The tests conducted on ordinary gasoline with an octane number of 82, premium gasoline with an octane number of 92, and M20 (consist of 20% methanol and 80% regular gasoline). The 2 liters Mercedes-Benz engine was used in the experiments.

The results showed that engine operation at idle speed emits high levels of CO, CO₂, HC, NOx and noise. The produced emission levels depend highly on fuel type. The premium gasoline (ON=92) represents the lower emissions level except for noise at all idling speed. Adding methanol to ordinary gasoline (ON=82) showed high levels of emi
