ISOLATION OF ENDOGENOUS LACTIC ACID BACTERIA AND DEVELOPMENT OF SILAGE OF PALM TREES LEAVES FOR LIVESTOCK IN QATAR
(2022 , Master Thesis)In Qatar, there are relatively low agricultural by-products available, mainly from palm trees for feeding livestock. Preservation of palm leaves is a problem due to harsh environmental conditions. Ensiling palm leaves with ... -
ISOLATION, IDENTIFICATION, DIFFERENTIATION AND SCREENING OF LOCAL AEROBIC UREOLYTIC BACTERIA INVOLVED IN MICROBIALLY INDUCED CALCIUM CARBONATE PRECIPITATION IN QATARI SOIL.
(2018 , Master Thesis)Biomineralization plays an important role in stabilizing the soil by modifying its geological and physical properties, hence, acting as a stabilizer against wind erosion specially in regions characterized by harsh soil ... -
Likelihood Inference for Step Stress Partially Accelerated Life Test Model with Type I Progressively Hybrid Censored Data from Generalized Exponential Distribution
(2021 , Master Thesis)This thesis considers the statistical inference on the generalized exponential distribution parameters in presence of progressive Type-I censoring under partially accelerated life test. The maximum likelihood method ... -
LINEAR AND BAYESIAN ESTIMATION OF THE PARAMETERS OF THE TYPE II GENERALIZED LOGISTIC DISTRIBUTION BASED ON PROGRESSIVELY TYPE II CENSORED DATA
(06-2 , Master Thesis)Generalized distributions have become widely used in applications recently. They are very flexible in data analysis, especially with skewed models that are important and occur frequently in many applications. In particular, ... -
Linking Soil Chemical Parameters and Arbuscular Mycorrhizal Fungal Communities in Qatar
(2020 , Master Thesis)Much of Qatar’s habitats are characterized by a hyper-arid climate, low rainfall and scarce soil nutrients; all of which combine to create a stress-induced environment for fungal development. Agricultural productivity ... -
