Among the different passive techniques heat pipe heat exchanger (HPHE) seems to be the most effective one for energy saving in heating ventilation and air conditioning system (HVAC). The applications for nanofluids with high conductivity are favorable to increase the thermal performance in HPHE. Even though the nanofluid has the higher heat conduction coefficient that dispels more heat theoretically but the higher concentration will make clustering .Clustering is a problem that must be solved before nanofluids can be considered for long-term practical uses. Results showed that the maximum value of relative power is 0.13 mW at nanofluid compared with other concentrations due to the low density of nanofluid at this concentration. For highe

The economic- Arabic relations reflect , without any doubt, the debate of the relation held between development and  what is not developed ; on the basis that these two phenomena  form the two polar of the Arabic economic as a system resulted out of the correlation nature presented between the Arabic world and the outer world. Accordingly, the present study focuses on the in- between Arabic  trade exchanges. There are many factors which relate the Arabic countries with each other . They all contribute in paying these exchanges through different historical decades. The trade relations between the Arabic countries have taken their manner from the base of the nonequivalent  development which is related in the distributio

The purpose of this study is to investigate learners' listening comprehension problems with Englishlectures. The study was guided by research question (What are the listening comprehension problems learners have with lectures in English).Furthermore; the main significant goal were declared through conducting this study, as well as providing some procedures of distribution the questionnaire of the study.Moreover, it presents several definitions of listening. This study definitely depends on questionnaire instrument to gathering the required data. The participants of the study were 30 learners completed their secondary school and joined at the college. Based on the findings among the five factors (text, speaker, task, environment, and list

This research deals with the dialects of the Arabian Peninsula, which is a group of dialects that belong to one language family. this term that was launched by Dr. Walaa Sadiq Al-Asadi in relation to the site from which the tribes speaking those dialects started, which is the Arabian Peninsula, and the word (dialects) was used  Instead of (languages) considering dialects emanate from collective language, which is what is called the mother tongue of those dialects

Das Verhaltnis des assimilierten arabischen VIII Stammes zum akkadischen

A fluorescence microscopy considered as a powerful imaging tool in biology and medicine. In addition to useful signal obtained from fluorescence microscopy, there are some defects in its images such as random variation in brightness, noise that caused by photon detection and some background pixels in the acquired fluorescence microscopic images appear wrongly auto-fluorescence property. All these practical limitations have a negative impact on the correct vision and analysis of the fluorescent microscope users. Our research enters the field of automation of image processing and image analysis using image processing techniques and applying this processing and analysis on one of the very important experiments in biology science. This research
