A parametric analysis of factors that determine head injury outcomes following equestrian fall accidents

Abstract This study examined the effects and interaction of four primary impact parameters (impact velocity, angle of impact relative to the ground, ground compliance and helmet impact location) on head kinematics and brain tissue response for falls that are most commonly associated with equestrian sports. A helmeted headform was subject to parametric tests using a rail guided launcher at three impact velocities (6, 9 and 12 m/s), four angles of incidence (15°, 30°, 45° and 60°), three ground compliance levels (High, Medium and Low) and three helmet locations (front, front-boss and rear-boss). Head kinematics were obtained from the headform and a finite element model was used to estimate brain tissue response. Velocity and angle had the largest effects on the risk of concussion, as measured by head kinematics and brain tissue response, while compliance and location were less influential. Interactions such as angle and compliance were found to greatly influence the risk of concussion. These findings suggest that an increased ground compliance can decrease linear acceleration and Head Injury Criterion (HIC) but not necessarily decrease rotational kinematics and brain tissue response. Consequently, the use of technological designs to attenuate rotational acceleration and decouple the helmet from that of the head may provide better safety than simply the addition of extra protective layers to the ground or a helmet liners.
Ethnobotanical Survey: A Comprehensive Review of Medicinal Plants Used Against Gastrointestinal Disorders in Niger, West Africa

Abstract Context: Gastrointestinal tract, a part of thehumandigestive system, is an important organ that is vulnerable to different disorders contributing substantially to morbidity and mortality rates worldwide, including in Niger. The majority of the people in Niger still use local medicinal plants to treat these ailments. This study aimed at reviewing the past and actual knowledge about the medicinal plants used to treat gastrointestinal disorders by Nigerien people of different provinces. Evidence Acquisition: Relevant data about the plant species used to treat gastrointestinal tract disorders were extracted from different studies and reports of the past and current ethnobotanical surveys conducted in Niger for a comprehensive review and a national scale analysis of their use. A statistical approach was used to determine the relative importance index in order to rank all species according to their usefulness. Results: A total of 140 plant species belonging to 50 families were recorded as being used by the Nigerien population to treat gastrointestinal disorders. Combretaceae (16/50), Mimosaceae (14/50), Caesalpiniaceae (13/50), and Fabaceae (12/50) were the botanical families with the most used species. In this review, Lannea acida, Acacia nilotica, Balanites aegyptiaca, Bauhinia rufescens, Boswellia dalzielli, Combretum micranthum, and Ziziphus mauritiana were ranked as the most cited plants. Phytochemical analyses of the plant extracts revealed the presence of tannins, terpenoids, steroids, and alkaloids in most of the plant species. Conclusions: The review and analysis of the medicinal plants reported through several ethnomedicinal surveys conducted in Niger have permitted to precisely provide substantial detailsonthe medicinal use of certain plants best to treat gastrointestinal disorders. These baseline comprehensive data could certainly attract most investigators to initiate further research that might lead to the development of new lead-drugs for the treatment of gastrointestinal disorders.
Ultrasound evaluation of Achilles tendon thickness in asymptomatic'-s: A reliability study.

Background: Achilles tendon disorders are among the most common maladies encountered in sports medicine. Increased tendon thickness is considered to be a risk factor for Achilles tendon disorders. Ultrasonography is currently the modality of choice that best demonstrate the Achilles tendon abnormalities. This study investigated Intra-rater reliability of ultrasound in Achilles tendon thickness measurements among asymptomatic’-s, performed by a qualified physiotherapist with limited ultrasound training. Method: A test retest reliability design was used. 25 healthy participants were recruited from Sheffield Hallam University. Achilles tendon thickness measurements were performed on two occasions, approximately 30 minutes apart; by the same rater, under same testing conditions. Results: The Intraclass correlation coefficient (ICC) for intra-rater reliability was found be excellent (ICC =0.935; 95% confidence interval, 0.88-0.96). Implications: Ultrasound can be used in the field of physiotherapy as a clinical tool for prevention, assessment and monitoring rehabilitation of athletes. Conclusion: Ultrasound evaluation of Achilles tendon thickness can be reliably performed by a qualified physiotherapist with limited ultrasound training. Further research is required to investigate inter rater reliability and among different patient populations with proper US training.

The Comparison of the Effect of the Head of Bed Elevation to 30 and 45 Degreess on the Incidence of Ventilator Associated Pneumonia and the Risk for Pressure Ulcers: A Controlled Randomized Clinical Trial

Background: The prevention of ventilator-associated pneumonia (VAP) can decrease the duration of mechanical ventilation, length of hospital stay, mortality, and healthcare costs. Objectives: The aim of this study was to compare the effect of the elevation of head of bed (HOB) to 30 and 45 degreess on the incidence of VAP. Methods: This study was a 3 group controlled randomized clinical trial. It consisted of 120 patients who were under mechanical ventilation and hospitalized in the intensive care unit (ICU) from February to July 2016 in the selected governmental hospitals of Iran University of Medical Sciences. The patients were allocated into 3 groups. The patients of intervention groups received interventions consisting of HOB elevation to 30 and 45 degreess for 3 consecutive days. The patients in the control group were in the routine position in the bed for 3 consecutive days. The HOB elevation was measured using the goniometer and recorded by nurses in perticular forms. At the end of the third day, VAP and pressure ulcers were evaluated using the clinical pulmonary infection score (CPIS) as well as Braden scales. The data were analyzed using descriptive and inferential statistics. Results: Statistically significant differences were reported in terms of VAP between the groups of the HOB evelation to 30 degrees (32.50%) and 45 degrees (20.00%) and control groups (52.50%) (P = 0.01). However, the mean scores of pressure ulcer showed no statistically significant differences between the groups (P = 0.625). The greatest change in position was performed by the staff nurses for nursing care in the group of 45 degrees elevation that reported as 6.125 ± 3.13 hours. Conclusions: The HOB elevation to 45 degrees helped with the prevention of VAP compared with the HOB elevation to 30 degrees as well as bed routine. Therefore, it is suggested that nurses elevate HOB to 45 degrees (more than 30 degrees) among mechanically-ventilated patients admitted to the ICU.
Establishing and Sustaining a Culture of Collegial Collaboration

Creating a cohesive team of coworkers can be challenging in any organization, and an academic department is no exception. The Centre College Mathematics Department has established a culture of collegial collaboration by investing in developing a strong mathematical community of faculty and students, and through careful attention to the hiring and mentoring of new faculty members. This article discusses our approach to creating and maintaining this culture in the midst of several transitions in leadership and personnel as well as multiple modifications to our curriculum and major. While the Centre College Mathematics Department is a relatively small group working at a liberal arts college, many of these ideas can be readily adapted to and implemented in departments of varying sizes and types.
Asianness in Hospitality: The Case of Luxury Hotels in Bangkok, Thailand

This paper aims to explore the extent to which two Asian and two non-Asian luxury hotel brands operating in the business district of Bangkok, Thailand, incorporate ‘Asianness’ into their designs and their operations as part of signaling luxury. As a specific approach to design and service provision in the luxury segment of the hotel sector, Asianness relies on particular traits of Asian culture such as sincerity, love, forgiveness, balance, and attention to small details. Various qualitative research techniques were used to collect data: interviews with managers from the four hotel brands, observation at these hotels, documentation (their official websites, and netnography (an analysis of reviews on TripAdvisor). Findings indicate that the four hoteliers incorporate Asianness in various degrees and various ways in the design and style of their hotels as well as in their customized services and in the customer-centricity of their approach to luxury. The level of Asianness (and “Thainess” in one case) is more consistent in the case of Asian luxury brands. Different characteristics of Asianness are nonetheless found across the four hotel brands.
Go-Around Detection Using Crowd-Sourced ADS-B Position Data

The decision of a flight crew to undertake a go-around, aborting a landing attempt, is primarily to ensure the safe conduct of a flight. Although go-arounds are rare, they do cause air traffic disruption, especially in busy airspace, due to the need to accommodate an aircraft in an unusual position, and a go-around can also result in knock-on delays due to the time taken for the aircraft to re-position, fit into the landing sequence and execute a successful landing. Therefore, it is important to understand and alleviate the factors that can result in a go-around. In this paper, I present a new method for automatically detecting go-around events in aircraft position data, such as that sent via the ADS-B system, and apply the method to one year of approach data for Chhatrapati Shivaji Maharaj International Airport (VABB) in Mumbai, India. I show that the method is significantly more accurate than other methods, detecting go-arounds with very few false positives or negatives. Finally, I use the new method to reveal that while there is no one cause for go-arounds at this airport, the majority can be attributed to weather and/or an unstable approach. I also show that one runway (14/32) has a significantly higher proportion of go-arounds than the other (09/27).
Laser welding of polymeric nanocomposites filled with silver nanoparticles produced by laser ablation

Ultra High Molecular Weight Poly Ethylene (UHMWPE) is a polymer with high performance features. It is typically transparent to the IR laser irradiation because of intrinsic structure. Thus, it needs of an adsorbent material, homogeneously distributed within it to generate absorbent bands in the IR regions. Silver nanoparticles, produced by laser ablation, can be added in different amount (1–6 weight %). These resulting nanocomposites have been prepared by a chemical mixing in an ultra-sonication bath. Sheets of nanocomposite plastic, prepared by a thermoforming process, were then sealed by means of a diode laser operating at 970 nm wavelength in continuum, with a maximum energy of 100 mJ and for a time of 60 seconds. Optical absorption features of the materials and the mechanical strength evaluation of the welded joints have been checked and discussed.

Instrument Development: Parental Satisfaction and Quality Indicators of Perinatal Palliative Care

The aim of this research was to produce an instrument that identifies and measures quality indicators and parental satisfaction in perinatal palliative care for parents who opt to continue a pregnancy with a life-limiting fetal diagnosis. The instrument was developed using current literature and recommendations from the National Consensus Project for Quality Palliative Care. A purposive sample of 14 experts provided guidance on construct and content validity. Open-ended questions and Likert scales were used to measure consensus about item relevancy. The instrument was piloted with parents to garner feedback on item clarity and relevance. Computer-mediated applications were used to conduct research using Delphi methodology. A panel of international experts participated until consensus was reached. Three rounds of analysis were completed to satisfy criteria for consensus related to constructs. Results indicate quality indicators can be defined and characterized. Items specific to parental needs during a pregnancy and birth were shown to be valid and were categorized into 8 domains of quality care. The instrument measures and reports patient-level data that will promote discipline-wide parental satisfaction and quality assessment and drive improvement initiatives. Use by clinicians and researchers will demonstrate a commitment to excellence and intentions to improve processes at the forefront of patient care.
Sum-Rate Capacity for Symmetric Gaussian Multiple Access Channels With Feedback

The feedback sum-rate capacity is established for the symmetric <inline-formula> <tex-math notation="LaTeX">$J$ </tex-math></inline-formula>-user Gaussian multiple-access channel (GMAC). The main contribution is a converse bound that combines the dependence-balance argument of Hekstra and Willems (1989) with a variant of the factorization of a convex envelope of Geng and Nair (2014). The converse bound matches the achievable sum-rate of the Fourier-Modulated Estimate Correction strategy of Kramer (2002).
Development of The OrSAEv Learning Materials: Preliminary Study of Student’s Knowledge about Earthquake and Tsunami Mitigation

Geologically, Indonesia is a disaster-prone country, especially tsunami. As a country has kind of disaster and so in the schools of Indonesia should be started to give education of hazard. Therefore, this study aims to determine the level of student knowledge about the earthquake and tsunami disasters, know the experience of students facing earthquake and tsunami disasters, and determine the conditions of counseling and disaster learning that have been applied in school. This type of research is a quantitative descriptive. The subjects of this study were 28 students of MTsN 7 Blitar. Data collection techniques carried out by observation, tests, and questionnaires. The sample of respondents was taken by purposive sampling based on advice from the science teacher at MTsN 7 Blitar. The results of the study are as follows: 1) In terms of the level of student knowledge about the earthquake and tsunami disasters can be categorized as less. 2) student’s experiences in facing with disasters and actions to save themselves in situations and conditions are categorized as not ready. 3) Disaster counseling and learning activities have never been carried out. After adding up the average percentage of each indicator, it is found that the knowledge and preparedness of the community in dealing with the earthquake and tsunami disaster based on their knowledge is still in the category of less prepared with a percentage of 47.9%, so there is still a need for better knowledge and readiness for students reach the level of full preparedness in the face of disaster. Learning methods and materials are needed that can be used to increase student knowledge about earthquake and tsunami mitigations. Therefore, it can be concluded that disaster learning materials need to be developed.
Heterogeneous deformation of two-dimensional materials for emerging functionalities

Atomically thin 2D materials exhibit strong intralayer covalent bonding and weak interlayer van der Waals interactions, offering unique high in-plane strength and out-of-plane flexibility. While atom-thick nature of 2D materials may cause uncontrolled intrinsic/extrinsic deformation in multiple length scales, it also provides new opportunities for exploring coupling between heterogeneous deformations and emerging functionalities in controllable and scalable ways for electronic, optical, and optoelectronic applications. In this review, we discuss (i) the mechanical characteristics of 2D materials, (ii) uncontrolled inherent deformation and extrinsic heterogeneity present in 2D materials, (iii) experimental strategies for controlled heterogeneous deformation of 2D materials, (iv) 3D structure-induced novel functionalities via crumple/wrinkle structure or kirigami structures, and (v) heterogeneous strain-induced emerging functionalities in exciton and phase engineering. Overall, heterogeneous deformation offers unique advantages for 2D materials research by enabling spatial tunability of 2D materials’ interactions with photons, electrons, and molecules in a programmable and controlled manner.
Microfabricated modular photoionization detector for volatile organic compounds

Air quality has become a major concern worldwide. Volatile organic compounds (VOCs) are hazardous chemicals that can cause cancer and are commonly found in indoor air. In Europe, increasing pressure from regulations on the VOCs exposure drive the need for portable, sensitive and fast gas analyzers. The gas chromatograph (GC) is a common gas analyzer and can be equipped with a photoionization detector (PID) for VOC analysis. Miniaturization of the PID can enhance the performance and portability of a GC gas analyzer. This work describes the design, fabrication and characterization of a micro PID (μPID) that can be integrated into a portable GC. The μPID uses a commercial UV lamp (with energy of 10.6 eV) emitting light into a microchannel, which is where the signal is measured. The device was microfabricated using micromilling and electrical discharge machining, with a final design that is modular. This enables the easy mount-dismount operation and replacement of components, while the miniaturized PIDs state of the art uses mainly fixed components. Four microchannel geometries are fabricated with varying electrode and illumination area and ionization chamber volume (1.1 μL to 6.7 μL). Low ionization chamber volume enables a reduction in sample volume, speeding up the analysis process and improving portability of gas analyzer. The prototype was tested for the four microchannel geometries with a direct injection of toluene 100 ppm and produced a signal from 0.5 to 2.5 nA. The results showed that the main geometrical parameters influencing the signal level were illumination area and electrode area. A detection limit down to 37 ppb for toluene can be reached if a digital moving average filter is applied to the signal for noise reduction. The μPID was also integrated with the portable GC from a French start-up company (In’Air Solutions), resulting in a GC-μPID gas analyzer. The GC-μPID results were obtained for an optimized cut-off frequency from a current preamplifier (fc =0.3 Hz), which provided the best signal-to-noise ratio. The detection limit of the GC-μPID was 73, 138, 308, 262 and 254 ppb, for benzene, toluene, ethylbenzene, m,p-xylene and oxylene, respectively. An analysis of the ionization chamber volume influence on the GC signal was evaluated and showed that, for the chamber volume and sample volumes used in this work, the variation in chamber size is not significant for a relevant GC signal change (measured by peak height and peak width change). Finally, a response of the GC-μPID when integrated with a preconcentrator (PC) in the sampling process is provided and showed that the whole system can have a detection limit lower than 5 ppb of toluene.
What patients want : a qualitative study of palliative careexperiences of HIV and AIDS patients and their families

The Patients’ Rights Charter (Health Professions Council of South Africa (HPCSA), (2008) stipulates the provision for “special needs in the case of persons living with HIV or AIDS” and palliative care that is both “affordable and effective”. But exactly what palliative support and care is wanted by HIV positive patients is not clear. This study explored the palliative care experiences of Human Immuno-deficiency Virus (HIV) and Acquired Immune Deficient Syndrome (AIDS) patients and their families. Interviews were performed, on patients and family members of other patients who had received palliative care in a small urban palliative care centre. The research question was, “What was your experience of being cared for in the care centre? ” Sampling was purposive and continued until saturation was reached (which was after ten interviews). The interviews were recorded and data transcribed verbatim. The data were analysed, identifying themes and sub-themes using a computer programme (Atlas.ti 6.1) and in collaboration with a co-coder. The study concluded that patients want good holistic care. The most important aspects of care named by the patients and their families were compassion, respect, dignity and spiritual support. The care that patients want is holistic, unsophisticated and relational. This kind of care is what is promoted as palliative care by the World Health Organisation.
