الإنسان معيار الحضارة
(
هيئة علماء السودان
, 2011 , Article)
لعل في مقدمة الإمكان الحضاري الذي تمتلكه الأمة، نوعية الإنسان وطبيعة القيم التي يلتزم بها، ومدي قابليتها لإقامة حضارة تعترف بإنسانية الإنسان، تجاهد في سبيل تحقيق حريته وعدم إكراهه على عقيدة لا يختارها، وتحول دون تسلط الإنسان ...
Chemical composition, cytotoxicity effect and antimicrobial activity of Ceratonia siliqua essential oil with preservative effects against Listeria inoculated in minced beef meat
(
Elsevier B.V.
, 2011 , Article)
The present study describes the phytochemical profile and the protective effects of Ceratonia siliqua pods essential oil (CsEO), a food and medicinal plant widely distributed in Tunisia. Twenty five different components ...
Regression estimator under inverse sampling to estimate arsenic contamination
(
John Wiley & Sons, Ltd
, 2011 , Article)
The fate of arsenic introduced to the environment as a result of the natural and human activities is an important issue. Surveys of arsenic typically involve sampling from a large area. Measuring arsenic concentrations in ...
Overcoming the production limitations of Photorhabdus temperata ssp. temperata strain K122 bioinsecticides in low-cost medium
(
Springer-Verlag
, 2011 , Article)
For low-cost production of Photorhabdus temperata ssp. temperata strain K122 bioinsecticide, a cheap complex medium was optimized. Diluted seawater was used as the source of micronutrients, especially sodium chloride, ...
A synchronous DQ frame controller via an LCL coupled filter under unbalanced three-phase voltage supply conditions
(
IEEE
, 2011 , Conference Paper)
This paper proposes a synchronous DQ frame current controller for inverter based interfaced systems. The grid voltage may be unbalanced, possibly due to unequal line impedance. The output active and reactive powers oscillate ...
The ICDAR2011 Arabic writer identification contest
(
IEEE
, 2011 , Conference Paper)
Arabic writer identification is a very active research field. However, no standard benchmark is available for researchers in this field. The aim of this competition is to gather researchers and compare recent advances in ...
Pharmacy student perceptions of public health service roles and responsibilities
(
Blackwell Publishing Ltd
, 2011 , Article)
Background There is increasing emphasis on pharmacists' assuming responsibility for public health promotion and delivery with formal expansion of public health activities in their practice. A number of pharmacy school ...
Harmonic rejection using multi-synchronous reference frame technique for CSI-based distributed generation with grid voltage distortion
(
IEEE
, 2011 , Conference Paper)
In the midst of the growing penetration of renewable energy resources and Distributed Generation (DG), power quality is one of the main concerns. Achieving low total harmonic distortion (THD) of exported current using low ...
Outage optimal resource allocation for two-hop multiuser multirelay cooperative communication in OFDMA upstream
(
IEEE
, 2011 , Conference Paper)
We investigate an outage optimal adaptive resource allocation scheme for the upstream of two-hop OFDMA based decode-and-forward cooperative relay systems. The objective of this work is to design resource allocation strategy, ...
A modified stationary reference frame-based predictive current control with zero steady-state error for LCL coupled inverter-based distributed generation systems
(
IEEE
, 2011 , Article)
This paper proposes a modified stationary reference frame-based predictive current controller with zero steady-state error for LCL coupled inverter-based distribution generation systems. Analytical expressions for the ...
