Effect of salinity on the microwave emission from dry soil surface

Manaf Ezzldien Al-Sabbagh; Jasim Khalaf Shallal; Sabah Hussein Ali

JOURNAL OF EDUCATION AND SCIENCE, Volume 19, Issue 4, Pages 1-13
DOI: 10.33899/edusj.2007.5923

ABSTRACT
The goal of this study was to apply the concept of passive microwave remote sensing to find the data set of microwave brightness temperatures of the dry soil surface as a function of actual salinity factors that influence the dielectric properties of the soil.



From the agricultural point of view, salinity factor refers to the state of accumulation of the soluble salts in the soil. In many area, this factor limiting plant growth (such as sodium chloride).
The measurements of the dielectric permittivity were conducted using shorted-circuited-waveguide technique at L-and C-band microwave frequencies (i.e. 1.4GHz and 5GHz, respectively). The dielectric properties of the salted soil samples were investigated at a thermodynamic temperature of 20.4 c .
The results show that the frequency of 1.4GHz (L-band) is more effective frequency for study of the penetration depth of the soil surface. Also the vertical polarized microwave signals is preferred to study the variation of the emission characteristics of the dry soil with respect to the salinity by using the microwave radiometric remote sensing techniques especially at low microwave frequency.

DOI: 10.33899/edusj.2007.5915

Abstract
This paper tackles the attitude of nursing staff towards the use of computers in hospitals especially in matters of documenting patients' records, and surgeries by Microsoft Access program which store data and other relevant information as information-bases set in tables and organized formulae, then displaying them in a way that facilitates access to data, storage of data and retrieve of data. Besides, this paper has designed a questionnaire consisting of question items regarding the attitudes of nurses made up of a sample of secondary school, health institutes and university graduates who currently practise or work at four hospitals in Nineveh district.
Their answers have been statistically analyzed by Microsoft Excel according to their qualifications.
Results confirmed hypothesis regarding the positive response to the use of computers since they reduce the paper work bulk, let alone the usefulness of computers as a clinical and administrative tool that is highly efficient in organizing nursing processes .However, the secondary school graduates do not find computers useful for their work.

Abstract It may be possible to find the Wiener polynomial with respect to a generalized distance of a compound graph constructed from two graphs having some kind of regularity. In this paper, we obtain the Wiener polynomials for a generalized distance of compound graphs constructed from a complete graph with some other special graph, such as a complete bipartite graph, a star, and a wheel, using binary operations defined by Gutman [4]. The Wiener index with respect to such generalized distance for each such compound graph is also obtained.الملخصإن وضع صیغة لمتعددة حدود وینر لتعمیم المسافة فی البیانات المرکبة یتطلب ان تکون البیانات المرکبة لها درجة من الانتظام, وهذا ینطبق على تراکیب بعض البیانات الخاصة التی لها انتظام معین, لذلک وجدنا من المناسب إیجاد حدودیات وینر لتعمیم المسافة للبیان المرکب من البیان التام مع بعض البیانات الخاصة مثلا البیان الثنائی التجزئة التام, وبیان النجمة, وبیان العجلة بإحدى العملیات الثنائیة المعرفة لـ[4] Gutman. وکذلک أوجدنا دلیل وینر لمتعددات الحدود لتعمیم المسافة لکل من البیانات المرکبة المذکورة سابقا.
