Abstract
Introduction The clinical presentation of endometriosis is extremely varied. Because endometriosis symptoms may overlap with symptoms caused by gastroenterological disorders, this can lead to misdiagnosis and a considerable delay in arriving at the correct diagnosis. The aim was to evaluate the type and duration of endometriosis-related symptoms and to identify predictors for patterns of involvement depending on symptoms.
Material and Method The data of 266 consecutive patients who were operated on in the Endometriosis Center between 1/2016 and 12/2017 after receiving a histologically verified diagnosis of endometriosis were recorded. In addition to recording the clinical parameters, a questionnaire was distributed to the patients, who were asked about their medical history. Infertile patients were grouped together as Group 1 and compared to non-infertile patients (Group 2).
Results The response rate for returned questionnaires was 79.47% (182/229). 41.8% of patients reported that they were infertile and 91.8% reported pelvic pain. In more than ⅓ of cases in both groups, more than 10 years passed between the initial symptoms and the final diagnosis (39.4 vs. 37.5%). On average, patients consulted 2.72 (± 1.58) resp. 3.08 (± 1.72) doctors before they presented to a hospital or were referred for laparoscopic diagnostic workup (p = 0.162). Cycle-related diarrhea (odds ratio 2.707; 95% CI: 1.063 – 6.895, p = 0.037) and dysmenorrhea (odds ratio 2.278; 95% CI: 1.193 – 4.348, p = 0.013) were associated with involvement of the pelvic peritoneum, cycle-related dyschezia was associated with rectal involvement by a factor of 4.6 in binary regression analysis (odds ratio 4.659; 95% CI: 1.132 – 19.186; p = 0.033).
Conclusion Cycle-related diarrhea and dysmenorrhea increase the risk probability of peritoneal endometriosis. Dyschezia increases the risk probability of rectal endometriosis.
Effects of Modified Constraint-Induced Movement Therapy in Real-World Arm Use in Young Children with Unilateral Cerebral Palsy: A Single-Blind Randomized Trial
Authors: Hwang Young Sub , Kwon Jeong-Yi 
Published: March 2020

Abstract
Objective To determine whether modified constraint-induced movement therapy (mCIMT) with continuous restraint is feasible and effective in improving the use of the paretic arm in the real world among infants and toddlers with unilateral cerebral palsy (CP).
Design Single-blind randomized controlled trial.
Setting Tertiary hospital.
Participants Children aged 7 to 36 months with unilateral CP (N = 24; 16 boys, 8 girls).
Intervention The experimental group received 2-hour clinic-based mCIMT sessions (5 days per week for 3 weeks), and a continuous restraint was applied.
Main Outcome Measures Standardized assessments were conducted. Peabody Developmental Motor Scales-2 (PDMS-2), Gross Motor Function Measure-66, Pediatric Motor Activity Log (PMAL), and Pediatric Evaluation of Disability Inventory were measured pre- and postintervention. Children who agreed to participate in the accelerometer study additionally wore accelerometers on both their wrists for 3 days before and after the intervention.
Results The mCIMT group exhibited greater improvement in PMAL-how often (p = 0.048; ηp2 = 0.173), PMAL-how well (p = 0.008; ηp2 = 0.289), and PDMS-2 visual motor integration (p = 0.014; ηp2 = 0.256) posttreatment than the control group. The percentage of time in moderate-to-vigorous physical activity (z = –2.24; p = 0.03) and vector magnitude average counts (z = –2.52; p = 0.01) significantly increased in children in who wore accelerometers (N = 8) after the 3-week mCIMT protocol.
Conclusion mCIMT with continuous restraint applied to infants and toddlers with unilateral CP appeared to have a positive effect on paretic hand use in the real world.

Uncommon Pathogens Causing Hospital-Acquired Infections in Postoperative Cardiac Surgical Patients
Authors: Sahu Manoj Kumar , George Netto , Rastogi Neha , Bipin Chalatti , Singh Sarvesh Pal 
Published: March 2020

AbstractBacterial infections are common causes of sepsis in the intensive care units. However, usually a finite number of Gram-negative bacteria cause sepsis (mostly according to the hospital flora). Some organisms such as Escherichia coli, Acinetobacter baumannii, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Staphylococcus aureus are relatively common. Others such as Stenotrophomonas maltophilia, Chryseobacterium indologenes, Shewanella putrefaciens, Ralstonia pickettii, Providencia, Morganella species, Nocardia, Elizabethkingia, Proteus, and Burkholderia are rare but of immense importance to public health, in view of the high mortality rates these are associated with. Being aware of these organisms, as the cause of hospital-acquired infections, helps in the prevention, treatment, and control of sepsis in the high-risk cardiac surgical patients including in heart transplants. Therefore, a basic understanding of when to suspect these organisms is important for clinical diagnosis and initiating therapeutic options. This review discusses some rarely appearing pathogens in our intensive care unit with respect to the spectrum of infections, and various antibiotics that were effective in managing these bacteria.

Published: March 2020

AbstractPseudotumor cerebri syndrome (PTCS) is characterized by raised intracranial pressure (ICP) with no neuroradiological abnormalities. Ocular ultrasound has been in use to measure optic nerve sheath diameter (ONSD), and retinal artery Doppler indices have been used for indirect assessment of ICP by pediatric intensivists. Here, we aimed to evaluate the correlation of the lumbar puncture (LP) opening pressure with the ultrasonographic ONSD and retinal resistive index (RRI) measures in patients with PTCS. And we wanted to find an answer to the following question: Can ultrasonographic ONSD measures serve as a follow-up tool in patients with PTCS? A prospective, single-center, case–control study was performed by pediatric intensive care and pediatric neurology departments. A total of 7 patients with PTCS were evaluated as patient group and 15 healthy children were evaluated as control group. The mean age of patient group was 138.8 ± 43.7 months. The mean right ONSD was 6.7 ± 0.5 mm and the mean left ONSD was 6.7 ± 0.6 mm. The mean right RRI value was 0.73 ± 0.03 and the mean left RRI was 0.73 ± 0.09. For the patient group, ONSD and RRI values of both eyes were statistically significant higher values than for the control group. The mean LP opening pressure was 56.57 ± 16.36 cmH2O. We detected strong, positive, and statistically significant correlations between the LP opening pressure and ONSD baseline measures for both the right eye (r = 0.882, p = 0.009) and the left eye (r = 0.649, p = 0.004). There was no correlation between opening pressure in LP and RRI measurements. We detected a statistically significant decrease in the right ONSD and left ONSD values and visual analog scale scores at the third-month follow-up. Our study results demonstrate that ultrasonographic ONSD measurements can be used as a noninvasive tool for assessment of the ICP at first admission and can be used as a follow-up tool in PTSC patients.

AbstractCompetition over land is at the core of many sustainable development challenges in Myanmar: villagers, companies, governments, ethnic minority groups, civil society organisations and non-governmental organisations from local to the international level claim access to and decision-making power over the use of land. Therefore, this article investigates the actor interactions influencing land-use changes and their impacts on the supply of ecosystem services and human well-being. We utilise a transdisciplinary mixed-methods approach and the analytical lens of the social-ecological systems framework. Results reveal that the links between land-use changes, ecosystem services and human well-being are multifaceted; For example ecosystem services can decline, while human well-being increases. We explain this finding through three different pathways to impact (changes in the resource systems, the governance systems or the broader social, economic and political context). We conclude with implications of these results for future sustainable land governance.

Published: March 2020

Abstract
Receiving a doctoral degree is a crucial step for those aiming
to research language-related real-world issues and to make scholarly
contributions to the interdisciplinary field of applied linguistics.
Applying to doctoral programs in applied linguistics requires a considerable
amount of time and effort, and there are limited resources on how to
successfully navigate this high-stakes process. This chapter aims to
demystify the process by drawing on the personal experiences of applied
linguistics faculty and doctoral students in North America. It also reports on the findings
of a study that surveyed 60 current doctoral students’ experiences and 12
faculty members’ recommendations related to choosing, applying to, and
getting accepted to doctoral programs in applied linguistics. The chapter
offers practical, data-based suggestions for prospective doctoral students
plotting their next steps as applied linguists.

Abstract
This chapter offers a view on successfully navigating
interpersonal and departmental dynamics in your pre-tenure years (and
beyond). It frames the discussion in terms of service, teaching, and
scholarship as well as other key aspects of departmental life. The chapter
provides a candid and practical assessment of the requirements and
expectations in these three major areas of junior faculty performance
evaluation and offers insights not typically found in departmental manuals.
Making good choices with your time and how these choices will impact your
progress toward tenure is a common theme running throughout the chapter.
Specific illustrative examples of many of the hazards junior faculty may
face are provided and concrete suggestions for avoiding these situations are
offered.

Published: March 2020

Abstract
The angular-dependent magnetoresistance (MR) in epitaxial Fe(001) films grown on MgO(001) is systematically investigated at room temperature. The resistivities with in-plane magnetic fields parallel (ρ

x
) and transverse (ρ

y
) to a current and a perpendicular field (ρ

z
) show a correlation of ρ

z
≈ ρ

x
> ρ

y
for Fe film thickness (d
Fe) between 3 and 50 nm, which is distinctly different from the conventional anisotropic MR relation of ρ

x
> ρ

y
≈ ρ

z
. The dependence of such unusual MR on d
Fe is quantitatively explained by the competition between the anomalous Hall MR, intrinsic anisotropic MR, and the MR induced by the geometrical size effect in Fe films. Our results also reveal the strong four-fold symmetric terms in the measured angular-dependent MR with a linear dependence of 1/d
Fe.
Replicating landmine blast loading in cellular in vitro models
Authors: Sory David R , Amin Harsh D , Chapman David J , Proud William G , Rankin Sara M 
Published: March 2020

Abstract
Trauma arising from landmines and improvised explosive devices promotes heterotopic ossification, the formation of extra-skeletal bone in non-osseous tissue. To date, experimental platforms that can replicate the loading parameter space relevant to improvised explosive device and landmine blast wave exposure have not been available to study the effects of such non-physiological mechanical loading on cells. Here, we present the design and calibration of three distinct in vitro experimental loading platforms that allow us to replicate the spectrum of loading conditions recorded in near-field blast wave exposure. We subjected cells in suspension or in a three-dimensional hydrogel to strain rates up to 6000 s−1 and pressure levels up to 45 MPa. Our results highlight that cellular activation is regulated in a non-linear fashion—not by a single mechanical parameter, it is the combined action of the applied mechanical pressure, rate of loading and loading impulse, along with the extracellular environment used to convey the pressure waves. Finally, our research indicates that PO MSCs are finely tuned to respond to mechanical stimuli that fall within defined ranges of loading.

Published: March 2020

Abstract
Metrological services from National Metrology Institutes related to energy gases have been supported by the programme of key comparisons of the Gas Analysis Working Group of the Consultative Committee for Amount of Substance: Metrology in Chemistry and Biology since its conception in 1993. Most of the key comparisons have been performed on natural gas composition measurement, which is key to the calculation of natural gas properties, thereby facilitating fiscal metering and the trade in natural gas. In the recent years, non-conventional energy gases and natural gas substitutes, such as refinery gas and biogas have been addressed. The paper gives an overview over the achievements in this area from the first key comparison (CCQM-K1) onward and outlines the current challenges to the metrological community. The ongoing energy transition towards renewable energy gases is at the centre of these challenges. The associated emerging challenges primarily concern the measurement of the concentrations of impurities, such as silicon in biomethane and upgraded biogas, carbon monoxide in hydrogen, and many others. The paper presents the first results of the development of measurement standards and methods for impurities in biogas, biomethane and hydrogen and the implications for the programme of key comparisons.
Ammonia Production from a Non-Grid Connected Floating Offshore Windfarm
Authors: Parmar Vismay , Manwell James , McGowan Jon 
Published: March 2020

Abstract
This paper investigates the technical and economic feasibility of a floating offshore wind driven ammonia production system. The ammonia plant is located on a floating plantship with no connection to the grid. An analytical model (MATLAB based) for this system was based on an all-electric Ammonia plant and the use of 4.5 MW wind turbines. The model results showed that ammonia was produced at a much lower capacity and at a cost about $350/ton higher than a land-based grid connected system. Future work recommended includes the use of larger sized wind turbines and cost reductions in the ammonia plant and efficiency increases in the auxiliary ammonia powered gas turbine system.
An Evaluation of Advanced Tools for Distributed Wind Turbine Performance Estimation
Authors: Poudel R.C. , Tinnesand H. , Baring-Gould I.E. 
Published: March 2020

Abstract
We evaluate various classes of distributed wind turbine performance tools across two sites in the United States. The class of tools ranges from the simple mass conservation model to the coupled Reynolds-averaged Navier-Stokes model, all initiated by the WIND Toolkit data set. The resource estimation at the site is evaluated against measured data at the mast location. Taking a sample 100-kW wind turbine and constant losses, we evaluate Openwind, Continuum, and WindNinja tools and document annual energy production (AEP) and time-series statistics associated with the performance estimation of the wind turbine. Using a methodology that is consistent and unbiased across the three options currently available in the industry, we elaborate results at the two sample locations and discuss the probable sources of discrepancy in the AEP estimates. Two main sources of the discrepancy come from the input WIND Toolkit data and the spatial modeling techniques of the tools to capture atmospheric physics. The discussion includes additional values that these tools may bring into the energy assessment process to enhance the owners’ confidence over the distributed wind power systems.
Can we predict short term extreme conditions from 10-minute data only?
Authors: Hannesdóttir Ásta , Larsen Gunner Chr. , Svensson Elin 
Published: March 2020

Abstract
In this study we compare 50-year return values of extreme estimates from a model to values estimated from data analysis. The outputs present a suite of extreme wind load conditions relevant for wind turbine design. The input parameters for the model consist of only statistical wind data, rather than high-frequency measurements that are less available. The model generally predicts lower extreme values than prescribed in the IEC wind turbine safety standard and is therefore of great interest to wind turbine manufacturers. This is the first time a systematic validation of the full suite of extreme models is performed in the whole wind speed range. The accuracy of the model predictions is estimated using a comprehensive data set from a complex terrain site. It is found that the mean absolute percentage error between the data analysis and the model outputs lies within the range of 8.1% - 65.8%.
Superelement reduction of substructures for sequential load calculations in OpenFAST
Authors: Branlard E. , Shields M. , Anderson B. , Damiani R. , Wendt F. , Jonkman J. , Musial W. , Foley B. 
Published: March 2020

Abstract
This article presents the superelement formulation newly implemented in OpenFAST to simulate fixed-bottom substructures with a reduced-order model similar to a common industry practice. The Guyan and Craig-Bampton methods are used to reduce the number of degrees of freedom and generate a so-called “superelement”. The formulation allows manufacturers to exchange such superelements to perform load calculations without revealing sensitive information about the support structure (e.g., foundation, substructure, and/or tower) or turbine. The source code is made publicly available in the OpenFAST repository. Test cases with varying degrees of complexity are presented to validate the technique, and accuracy issues are discussed.
Probabilistic analysis of offshore geotechnical site investigation in a homogeneous stiff clay deposit
Authors: Luo N , Arwade S R , DeGroot D J 
Published: March 2020

Abstract
Unlike most onshore geotechnical projects, conducting offshore site investigations is often difficult and technically challenging due to the harsh ocean environment. Hence, an important cost consideration is minimizing the number of soundings for an offshore project while ensuring reliable and safe designs. This study examines the possibility of reducing the number of soundings at site by using practical numerical tools to predict cone tip resistance (qt
) at unsampled locations. Prediction errors were quantified within a probabilistic framework. Two prediction approaches, i.e. 2D linear regression and Kriging, were adopted. Site investigation data from an existing offshore wind farm with homogeneous stiff clay deposit were collected and analyzed. Result shows that in a homogeneous soil deposit, it is possible to use as little as 20% of the available data to predict the remaining 80% qt
profiles with small error. Monopile deformation under typical design load was also calculated using shear strength derived from the qt
profile at each wind turbine location. The small spatial variation of monopile deformation suggests that a reduction in the number of geotechnical soundings for sites with uniform soil conditions would not significantly impact the foundation design.
Offshore Renewable Energy Planning in French Law: towards an integrated process?
Authors: Boillet N 
Published: March 2020

Abstract
The production potential of offshore renewable energy meets the objectives of energy and climate policy at international and European level. Under French law, the necessary planning for the development of the offshore renewable energies is carried out within the framework of energy law. This situation, which was not entirely satisfactory in terms of participation and respect for the marine environment, has led to legal developments. In particular, the planning method chosen should be improved through the implementation of MSP. The purpose of this article is to present the planning of offshore renewable energies under French law and to analyze its relevance.
Economic Sensitivities and Options Surrounding Wind Farm Life Extension
Authors: Carriveau R , Miller L 
Published: March 2020

Abstract
Some North American wind owners and operators are approaching and surpassing the halfway points of their power purchase agreements (PPAs). The initial 20-year contracts were intended to align with the operational life of the assets, however it is expected that some assets will continue to be operational if proactively maintained. An LCOEEXT was previously proposed to evaluate the economic feasibility of lifetime extension. This metric is sensitive to many variables and a robust analysis of these sensitivities will provide improved guidance when considering lifetime extension. Lifetime extension is an attractive option, offering higher rates of return for projects when economic analysis supports this pursuit. Options for operating beyond the first PPA are also detailed and discussed.
Remaining Useful Life Determination for Wind Turbines
Authors: Pagitsch Michael , Jacobs Georg , Bosse Dennis 
Published: March 2020

Abstract
Since wind turbines have become one of the prevailing sources of electrical energy, their reliability and availability are of enormous importance. Predictive maintenance is a strategy for keeping both factors high and thus heavily under research. Maintenance based on the actual condition of a turbine would be the ideal way in the field of tension between benefit and effort. However, determining the condition of machine parts and elements traditionally requires the expensive application of measurement techniques and inspections. In many cases load-based maintenance – powered by few simple sensors and a model-based derivation of the condition from the history of loads – would be a good compromise. This paper presents a novel method for modeling wind turbines with minimal data requirements for the purpose of calculating inner loads and deriving the condition of machine elements. The applicability is demonstrated in the form of a remaining useful lifetime estimation of gearbox bearings.
