Water evaporation, Highly arid regions, Dead Sea

This study was conducted to estimate the evaporation rate in an arid region; namely the Dead Sea. Estimation of evaporation helps in planning, operation and management of water resources. Direct measurement of evaporation rates on daily basis extended for one year. Daily energy-budget and Penman's evaporation rates were determined from available data to quantify evaporation rates and to assess the assumptions associated with Penman's method for use in an area characterized as arid. An attempt was made to correlate the evaporation rate with the meteorological data affecting it. A procedure was developed and found suitable for calculating the evaporation rate from the sea site and other similar regions of high aridity

Multi-dimensional Laplace transforms and applications

In this dissertation we establish new theorems for computing certain types of multidimensional Laplace transform pairs from known one-dimensional Laplace transforms. The theorems are applied to the most commonly used special functions and so we obtain many two and three dimensional Laplace transform pairs. As applications, some boundary-value problems involving linear partial differential equations are solved by the use of multi-dimensional Laplace transformation. Also we establish some relations between the Laplace transformation and other integral transformations in two variables

An exploration of the impact of international and domestic factors on economic reform programmes in Libya 1987-2004

This thesis seeks to explore the changes of the Libyan economy, which began in the mid-1980s. The core of this research is to examine the influence of these changes on the course of the state and the implementation of the economic reform programmes. The relevant theoretical literature is based upon the relationship between the international and internal factors leading up the economic reform. The globalisation and state power are reviewed. The theory of rentier state and also the discussion of the most relevant aspects of the privatisation process were considered. The contribution of the thesis is its sustained analysis of the Libyan economic policies and, more importantly, its response to the neglect of the international and domestic influences of the economic reform process particularly in oil states. In addition, the literature on Libya and its structural and economic reform suffers from a lack of theoretically-grounded analysis. The methodology of this study is based upon combination of both interviews and questionnaires seemed the ideal methods in examining the economic reform and the privatisation programmes. The documentary research was also an important element for this study. In order to identify the determinants of the changes of the Libyan economy and the implementation process, it employs a variety of Libyan official documents and economic data. In general the study reveals that the relationship and the interaction between the international and domestic factors is extremely vital to understand the economic reform and privatisation programmes in Libya. Despite the significance of the international arena, its impacts are mitigated through the domestic context. Moreover, the previous state policies, the role of the state institutions and the interaction between the state apparatus and the Libyan society are important in understanding the Libyan economy

The Umayyad Emirate House Dar El Emara Al Omawia - in Jerusalem

This study is conducted under the title The Umayyad Emirate House . This House is located at the southern and western sites of Haram al-Sharif in Jerusalem. This House, which was the center of the Umayyad Administration, its landmarks were completely obliterated and a Torah Park and a museum were built on its ruins. This museum reflects the Jewish history and the park is a touristic place known by Mataher Al Haykal . In the first chapter, the researcher handled the conquest of Jerusalem and the developments which occurred to this city during the peak of Islam and the Umayyad State: In the Second chapter, the researcher presented Jerusalem as the Capital of the Jond Palestine: In the Third chapter the researcher handled the discovery, monuments and building of the Umayyad House and its ruins: In the Fourth chapter the researcher handled the judaization of the Umayyad Emirate House, the obliteration of its landmarks and the construction of both a Torah park named »King David Park» and a museum on its ruins. This museum addresses the stages of the Jewish History in Palestine. Moreover, outside the current walls of Jerusalem, where the Umayyad Emirate House extends, a tourist station named Mataher Al Haykal was established as a station of the Talmudian Tourist Road which connects south Jerusalem to North Jerusalem passing through its Old City district. The action of distortion and obliteration of this Islamic site, as a part of the methodological judaization of the city, is considered a serious challenge and clear violation for all international conventions and treaties that recognize Jerusalem as an occupied city. Also, the constructions which were established on the Umayyad Emirate House is considered as an explicit infringement, breaching and unrightful desecration of the lands of Islamic Waqf in this Holy City

Change management capability maturity model for contractors in the Kuwaiti construction industry

This research aims to improve the implementation of project change management by contractors to secure better outcomes in construction projects. An empirically designed and tested change management capability maturity model was developed to be used as an infrastructure for boosting the change management capabilities for contractors in Kuwait. This research commenced with an extensive literature review to understand project changes and the implementation of project change management by contractors. This literature review was followed by semi-structured interviews with contractors to allow for a deeper understanding of the success criteria of change management. To validate this criteria, a quantitative questionnaire survey took place and indicated 52 change management success criteria from the perspective of contractors in Kuwait. These success criterions (represented by practices and tools) were grouped using the principal component analysis (PCA) technique and assigned weights within their designated groups using the Analytic Hierarchy Process (AHP) and Delphi technique to indicate their relevant significance within a successful change management process. As a result, the Change Management Capability Maturity Model (CMCMM) was constructed to evaluate the contractor’s capability to conduct a prosperous change management process according to the previously concluded success criteria. The model was reviewed by domain experts and by conducting several case studies to substantiate its fitness for purpose and practicality. The case studies also showed that CMCMM was effective in indicating the change management process gaps and successfully outlined the pathway of process improvement and Institutionalisation. The research contributes to the body of knowledge related to construction management and capability maturity models in addition to having several practical implications. This contribution is represented by the development of an empirically based capability maturity model that uses a validated and weighted criteria within each stage of project change management process to evaluate the contractor’s ability to conduct project change management process. The research also provides a step-by-step user guide to enable the proper usage of CMCMM and enhance the model’s degree of usability by new users in the organisation

Suppression of Phytophthora infestans in Potatoes by Foliar Application of Food Nutrients and Compost Tea

Abstract: The efficacy of compost tea (CT), food nutrients (FD), and manzate (MZ) applied foliarly against late blight (Phytophthora infestans) of potato (Solanum tuberosum L.) 'Green Mountain' and 'Russet Burbank' was evaluated in greenhouse trials conducted in New Brunswick, Canada. Percent of late blight incidence and severity were assessed four weeks after treatment and inoculation. Relative to the untreated control treatments, MZ reduced late blight severity by 92% and 99%; CT reduced severity by 29% and 27%; and FD reduced severity by 22 and 35% in 'Green Mountain' and 'Russet Burbank', respectively. In a separate study on the cultivar 'Shepody' comprising of 13 different treatments including combinations of compost tea and food nutrients, treatment with a combination of compost tea and seaweed extract resulted in 36% reduction in late blight severity relative to the inoculated control treatment. The combinations of CT + whey, CT + potassium bicarbonate, CT + Neptune's, and CT + organic gem reduced disease severity by 21, 10, 10, and 5%, respectively, relative to the inoculated control treatment. The results of this study shed the light on the potentially positive effect of combinations of compost tea and food nutrients as an alternative, relatively cheap, and environmentally safe tool for late blight control in potatoes. Such new tools are essential for fungicide resistance management

Antimicrobial Activity of Extracts from Leaves, Stems and Flowers of Euphorbia macroclada against plant pathogenic fungi

Extracts drawn from dried and powdered flowers, stems and leaves of Euphorbia macroclada with some organic solvents were tested for antimicrobial effect against the fungi Verticillium dahliae, Fusarium oxysporum, Rhizopus stolonifer, Penicillium italicum, Rhizoctonia solani, Alternaria solani, Stemphylium solani, Cladosporium sp., Mucor sp., and Pythium sp. The strongest inhibitory effect of the extracts was observed against R. solani, V. dahliae, F. oxysporum, Pythium sp. and R. stolonifer. The weakest effect was against A. solani. Extracts from the stems had a stronger inhibitory effect than those from the flowers or leaves. Butanol was the best solvent to extract antimicrobial compounds from leaves, stems and flowers and was superior to chloroform, water and petroleum ether. Results clearly indicate that E. macroclada is a promising source of antimicrobial compounds
