A Comparative Study of Organic and Mineral Acids in the Release of Potassium from Potassium Feldspar Minerals
...Show More Authors
Abstract<p>A study conducted a laboratory experiment to measure the release of potassium and the dissolution of feldspar minerals in soils from different locations in Karbala Province (Ain Al-tamur, Qasr Al-Akhyar, Fadak Farm). The study involved the addition of organic acids (fulvic and humic) and mineral acids (sulfuric and phosphoric) at concentrations of 5% and 10% to sand-separated soil samples obtained through wet sieving. Feldspar minerals were identified using a polarized light microscope, and the percentage of each type of feldspar mineral was calculated. The results demonstrated that organic acids outperformed mineral acids in releasing potassium at both concentrations. Among the organic acids, fulvic acid released more potassium than humic acid, with the highest amounts recorded at the Qasr Al-Akhyar site (198.65 and 246.67 mg kg<sup>−1</sup> for 5% and 10% concentrations, respectively). In comparison, the values for humic acid at the same site were 142.75 and 194.60 mg kg<sup>−1</sup> for 5% and 10% concentrations, respectively. For mineral acids, sulfuric acid released the highest amount of potassium, reaching 100.88 mg kg<sup>−1</sup> at a 10% concentration at the Qasr Al-Akhyar site, while the lowest value was recorded with phosphoric acid at a 5% concentration, measuring 69.23 mg kg<sup>−1</sup> at the Ain Al-tamur.site. Feldspar minerals were identified in both plagioclase and potassium feldspar forms. Plagioclase feldspars accounted for 9.14%, 13.12%, and 9.12% at the Ain Al-tamur., Qasr Al-Akhyar, and Fadak Farm sites, respectively. potassium feldspars constituted 11.65%, 22.80%, and 13.25% in the sand-separated samples from the three sites.</p>

The extent of the possibility of compensating for the obstruction of the view (vision) as a result of the establishment of public projects - a legal study in light of the position of the American courts
...Show More Authors

Despite the great economic and commercial importance given to real estate by virtue of its view of the landscape or public roads, US courts have differed in their position on compensation for damages resulting from blocking that view or vision by public projects. Some courts compensated for such damages, other courts approved such compensation. Hence, this research came to shed light on the extent of the possibility of compensation for blocking the view or vision as a result of public projects, and the research has supported us with many judicial decisions.

There is no doubt that the field of education and teaching (in any country and whatever its ruling system varies “d”) is considered one of the most specific and sensitive field, because it is related to the building of human. And as the human is a purpose (aim) and the means in the same time and he is the strategist capital, so he way of his rearing, education, choosing the educator, methods of working and the aims are considered serious matters.

Comparative Effects of Fentanyl, Medazolam, Lignocaine and Propranolol on Controlling the Hemodynamic Pressor Response during Laryngoscopy and Intubation
...Show More Authors

Laryngoscopy and tracheal intubation are considered the most invasive stimuli in anesthesia. They provoked cardiovascular responses that include hypertension, tachycardia and dysrhythmias. Various pharmacological approaches have been used to blunt or attenuate such pressor responses. The present study was designed to evaluate the effect of medazolom, lignocaine and propranolol as a valuable adjuvant to fentanyl in attenuating hemodynamic responses to endotracheal intubation in normotensive patients. Thirty two patient with physical status I or II according to the score of American Society of Anesthesiologist (ASA), scheduled for elective surgery under standard general anesthesia, were randomly allocated into four groups (8 patients in ea

Conjugated Polymer (MEH-PPV:MWCNTs) Organic Nanocomposite for Photodetector Application
...Show More Authors

Fabrication of a photodetector consists of the conjugated polymer "MEH-PPV"- poly (2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenlenevinylene) and MEH-PPV:MWCNT nanocomposite thin film. The volume ratio investigated was 0.75:0.25. MEH-PPV was dissolved in chloroform solvent and doped with MWCNTs. The spin coating method was used to achieve a facile and low cost photodetector. The absorption spectrum decreases by adding the CNTs. The PL spectrum detected recombination curve results by doping the polymer with CNTs, and AFM measurement showed an increase of roughness average from (0.168 to 2.43nm) of "MEH-PPV" and "MEH-PPV:CNTs", respectively. The doping ratio 0.25, which has a higher photoresponsivity, was evaluated at 1.70 A/W and 2.14 A/W of th

The objective of this study is to explain the role of credit policies in agricultural development of Iraq during the period 1979-1989 which were represented by the policy of co-operative agricultural bank the organization that responsible to finance agricultural sector for various reasons. It has been shown that there was no clear credit policy existed during the period concerned due to the differences between loans from year. The loan growth rate was low in general comparing with objectives of the agricultural development plans, a low production rates comparing with loans paid, the growth rate of average number of trees in each donum and the growth rate of livestock number was also low.In conclusion there should be a clear plan for cred
