Environmental Factors Affecting the Growth and Enzymatic Activity of Ceratocystis Radicicolathe Causal Agent of Black Scorch Disease on Date Palm
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Background: Ceratocystis radicicola is a soil-borne pathogen (Wingfield et al, 1993) causing sudden death of date palm (Phoenix dactylifera) in USA and South Africa (Bliss, 1941; Lind & Smit, 1999). It also has been reported ... -
Environmental impact of utilization of “produced water” from oil and gas operations in turfgrass systems
( Nature Research , 2020 , Article)© 2020, The Author(s). This study attempted to use produced water (PW) to irrigate turfgrass species, Cynodon dactylon and Paspalum sp. Assessment on established grasses, heavy metal accumulation and germination tests for ... -
Enzymatic treatment of peanut butter to reduce the concentration of major peanut allergens
( John Wiley & Sons, Ltd. , 2013 , Article)This study investigated the effects of enzymatic treatment of peanut butter on two-major peanut allergens (Ara h 1 and Ara h 2). Home-made and commercial peanut butter samples were treated with alpha-chymotrypsin, trypsin ... -
Epibenthic communities from offshore platforms in the Arabian Gulf are structured by platform age and depth
( Elsevier Ltd , 2021 , Article)Oil and gas platforms act as artificial habitats for a myriad of marine organisms. In this study, we used opportunistic remotely operated vehicle (ROV) data to describe fouling assemblages through the characterization of ... -

Error-feedback temperature regulation for a reverse flow reactor driven by a distributed parameter exosystem
( Elsevier , 2022 , Article)This work is devoted to solve the state and error-feedback control problems for a catalytic reverse flow reactor (CFRR), which is modeled by nonlinear partial differential equations (PDEs). These two regulation problems ... -
Estimating carbon dynamics in an intact lowland mixed dipterocarp forest using a forest carbon model
( MDPI AG , 2017 , Article)Intact dipterocarp forests in Asia act as crucial carbon (C) reservoirs, and it is therefore important to investigate the C dynamics in these forests. We estimated C dynamics, together with net ecosystem production (NEP), ... -
Estimating the age-dependent changes in carbon stocks of Scots pine (Pinus sylvestris L.) stands in Turkey
( Springer-Verlag France , 2016 , Article)Key message Simulated and observed carbon stocks in Scots pine forests varied considerably with stand age. The contribution of biomass to the total forest carbon stocks increased and that of dead organic matter decreased ... -
Estimating the carbon dynamics of South Korean forests from 1954 to 2012
( Copernicus GmbH , 2014 , Article)Forests play an important role in the global carbon (C) cycle, and the South Korean forests also contribute to this global C cycle. While the South Korean forest ecosystem was almost completely destroyed by exploitation ... -
