Modeling of active crack damage control and the active fatigue damage control of adhesive joint
Active damage control is a new technique which mimics the self-repairing capability of biological beings and can be used to greatly increase the structural integrity and fatigue life. This thesis describes two approaches used in active damage control: direct stress cancellation and indirect stress …

Damage Control Measures in Composites: Focus on Damage Tolerance of Aerospace Structures
<p>Barely Visible Impact Damage (BVID) in composite materials presents a stealthy yet significant risk to structural integrity, particularly challenging due to its elusive nature. The approach adopted here diverges from traditional methodologies, focusing on the novel application of Digital Image …

Post-Earthquake Damage Repair and Probabilistic Damage Control Approach for Reinforced Concrete Bridges
… reinforced polymers (CFRP) and probabilistic damage control approach (PDCA) for reinforced concrete (RC) bridges. To develop repair methods, first repair objectives were defined. To define repair objectives, internal earthquake damage was quantified and correlated to a series of visible damage …

Damage control laparatomy for abdominal gunshot wounds: indications, mortality and long term outcomes
Background: Outcomes of patients subjected to damage control laparotomy (DCL) for abdominal gunshot wounds (GSWs) remains relatively unknown. There is limited evidence as to which variables may reliably predict morbidity and mortality. The aim of this study was to evaluate the impact of DCL on long …

Review of Damage Control Laparotomy (DCL) outcomes in a Major Urban Trauma Center
Introduction Damage control laparotomy (DCL) in an urban trauma centre is associated with high mortality. Aim The purpose of this prospective study was to review the outcomes of DCL in a level one urban trauma centre, looking particularly at primary closure rate and other factors influencing …

An experimental investigation into active damage control systems using positive position feedback for AVC
… Position Feedback (PPF) for Active Vibration Control as part of an Active Damage Control System (ADCS). Vibration control increases the fatigue life of a structure and decreases the in-plane stresses that can cause delamination in a composite. PPF is a collocated direct-output feedback control …

Genome-wide microscopy screening identifies links across processes including a conserved connection between DNA damage control and the microtubule cytoskeleton
… and accurate results through inclusion of many controls across multiple screening repeats. In total, over 4.5 million images from approximately 19 000 biologically independent cell populations were imaged and analysed. All strains screened contained GFP-labelled tubulin (GFP-Atb2) allowing …

A solution to the inherent list on Nimitz class aircraft carriers
… an inherent list to starboard that their list control systems (LCS) are typically unable to correct while under Combat Load Conditions. As a result, it has become necessary to use fresh water ballast in a number of inner bottom voids and damage control voids to augment the LCS. Maintaining …

Impact of nighttime versus daytime emergency surgery on the outcome of necrotising enterocolitis
… transfusion rates were higher at NT (p=.03). “Damage control” surgery was more common at NT (p=.01) and associated with 25% 30-day mortality compared to 33% for other patients (p=.03). Other operative characteristics and intraoperative AE were similar. Thirty-day mortality and enterostomy …
