Experimental detection of localized surface defects in ball bearings using vibration analysis
(
Canadian Acoustical Association
, 2019 , Conference Paper)
This study aimed at the monitoring of bearing health condition, based on vibration measurement. For that purpose, small circular defects were seeded on outer and inner rings of similar bearings, by using the principle of ...
Active control of noise in ventilation ducts
(
Canadian Acoustical Association
, 2019 , Conference Paper)
Ventilation ducts are often lined with passive absorption material for both thermal insulation and noise and vibration reduction. However, the noise reduction performance is not significant at low frequencies. Active Noise ...
A computational model to predict the structural and functional consequences of missense mutations in O6-methylguanine DNA methyltransferase
(
Elsevier
, 2019 , Article)
DNA repair mechanism is a process through which the cell repairs its damaged DNA. Although there are several mechanisms involved in the DNA repair mechanisms, the direct reversal method is the simplest and does not require ...
P-value driven methods were underpowered to detect publication bias: analysis of Cochrane review meta-analyses
(
Elsevier
, 2019 , Article)
To investigate the effect of number of studies in a meta-analysis on the detection of publication bias using p-value driven methods. The proportion of meta-analyses detected by Egger's, Harbord's, Peters', and Begg's tests ...
PD-L1 status in breast cancer: Current view and perspectives.
(
Elsevier
, 2019 , Article)
Breast cancer was traditionally not considered a particularly immunogenic tumor. However, recent developments have shown that some aggressive triple-negative breast cancers are immunogenic, exhibit a resistance to chemotherapy ...
Redefining the climate niche of plant species: A novel approach for realistic predictions of species distribution under climate change
(
Elsevier
, 2019 , Article)
Climate change is increasingly affecting plant species distributions, in ways that need to be predicted. Here, in a novel prediction approach, we developed the relevant climate niche (RCN) of plants, based on thorough ...
Baseline concentrations of mercury species within sediments from Qatar's coastal marine zone
(
Elsevier
, 2019 , Article)
Baseline concentration of total mercury (THg), organic extractable mercury and methylmercury (CH3Hg) concentrations in sediments from the northeastern, eastern and southeastern parts of the Arabian Gulf were assessed. ...
The State of Qatar and the United Arab Emirates
(
Elsevier
, 2019 , Article)
This chapter discusses the principles of road traffic signal control in the State of Qatar and the United Arab Emirate (UAE). In the first section, traffic control standards used in both countries are presented with a focus ...
Surface modification of polymeric substrates with photo- and sonochemically designed macromolecular grafts
(
wiley
