Smart optimized structural control of onshore wind turbines with MR dampers
This paper presents an effective control approach for structural vibration of onshore wind turbines in the edgewise direction. Huge multi mega-watt wind turbines are currently developed to harvest large amounts of energy from the wind. Such designs require the construction of huge slender blades and towers which conse quently lead to undesirable structural deformations that hinder the power production and reduce life span of the wind turbine. Many researchers have worked on structural control of wind turbines. However, these efforts neither have resulted in an effective reliable mitigation for deformation of structural elements, nor they have achieved an economical solution in terms of actuators exploitation. The work presented in this paper, however, introduces a particle swarm optimisation-based semi-active controller which exploits magnetorheological dampers to mitigate edgewise blade displacements. Dampers are modelled using neural networks for they are capable of predicting future forces and eliminating control lag. The developed controller is tested at several configurations of actuators placement on a benchmark 5-MW wind turbine. The proposed approach, indeed, showed a significant reduction of over 80% in the peak responses and about 77% of peak-to-peak response of blades against uncontrolled and passive systems which leads to promoting longevity of wind turbines
Developing and Validating of a Managerial Procedures Manual for Head Nurses
The managerial skills are a set of behaviors based on knowledge that can be learned through procedure. Procedures are descriptions of how to carry out an activity. Procedures manual is essential to ensure consistency and quality in products and services. The aim of this study was to develop and validate a managerial procedure manual for head nurses at Ain-shams University Hospital. The study was conducted in Ain Shams University Hospital using operational design. It included a group of 78 head nurses for assessment and a jury group consisting of 16 faculty members of Nursing Administration and 8 nursing directors and assistants. Data were collected using a head nurses' self-administered questionnaire and opinionnaire form for the jury group. The researchers discussed the idea of the study with representatives of the hospital administration to reach to an agreement regarding the importance of the proposed manual and its content, then assessed head nurses’ view of the importance of a managerial manual. The results showed that 25.6% of the head nurses did not know about the presence of a manual for managerial nursing procedures, 96.2% expressed the need for such manual, and 70.7% reported having faced problems due to lack of such manual. Based on analysis of the data the researchers developed the manual that was validated by the jury group, and distributed to head nurses after approval of the hospital administration. The hospital administration participated in all steps of the development of the manual, and adopted its use in the setting. The effectiveness of the manual in reducing head nurses' stress related to managerial problems needs to be assessed after a few months of implementation.

Trauma ICU Prevalence Project: the diversity of surgical critical care.
Background:Surgical critical care is crucial to the care of trauma and surgical patients. This study was designed to provide a contemporary assessment of patient types, injuries, and conditions in intensive care units (ICU) caring for trauma patients. Methods:This was a multicenter prevalence study of the American Association for the Surgery of Trauma; data were collected on all patients present in participating centers' trauma ICU (TICU) on November 2, 2017 and April 10, 2018. Results:Forty-nine centers submitted data on 1416 patients. Median age was 58 years (IQR 41-70). Patient types included trauma (n=665, 46.9%), non-trauma surgical (n=536, 37.8%), medical (n=204, 14.4% overall), or unspecified (n=11). Surgical intensivists managed 73.1% of patients. Of ICU-specific diagnoses, 57% were pulmonary related. Multiple high-intensity diagnoses were represented (septic shock, 10.2%; multiple organ failure, 5.58%; adult respiratory distress syndrome, 4.38%). Hemorrhagic shock was seen in 11.6% of trauma patients and 6.55% of all patients. The most common traumatic injuries were rib fractures (41.6%), brain (38.8%), hemothorax/pneumothorax (30.8%), and facial fractures (23.7%). Forty-four percent were on mechanical ventilation, and 17.6% had a tracheostomy. One-third (33%) had an infection, and over half (54.3%) were on antibiotics. Operations were performed in 70.2%, with 23.7% having abdominal surgery. At 30 days, 5.4% were still in the ICU. Median ICU length of stay was 9 days (IQR 4-20). 30-day mortality was 11.2%. Conclusions:Patient acuity in TICUs in the USA is very high, as is the breadth of pathology and the interventions provided. Non-trauma patients constitute a significant proportion of TICU care. Further assessment of the global predictors of outcome is needed to inform the education, research, clinical practice, and staffing of surgical critical care providers. Level of evidence:IV, prospective observational study

Survivorship support in head and neck cancer: American Head and Neck Society survey
BackgroundThe value of supporting cancer survivors beyond formal treatment has become increasingly recognized among clinicians who care for patients with head and neck cancer.MethodsA survey was developed by the American Head and Neck Society (AHNS) Survivorship Committee and distributed to members of the AHNS electronically.ResultsThe survey was distributed to 1403 AHNS members, with 202 responses (14.4%). Among survivorship topics, respondents were most likely to address detection of recurrence/second primary malignancies (97.5%), dysphagia (93.1%), and thyroid function (90.1%) with their patients; they were least likely to address sleep disturbance/apnea (27.7%) and body and self‐image issues (29.7%.) Less than half provide patients with a written treatment summary (43.1%) or follow‐up care plan (36.9%).ConclusionsThese results highlight the need for improved survivorship care planning and offer an opportunity for the development of educational and survivorship research in head and neck cancer care.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/154907/1/hed26066_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154907/2/hed26066.pd
