ADAPTIVE TOOLPATH FOR 3-AXIS MILLING OF THIN WALLED PARTS

In this paper a technique to compute the 3-axis toolpath for a thin-wall component is presented aiming at maximizing the engagement conditions, keeping the geometry in tolerance. The toolpath generation is based on the static deflection of the component, predicted by coupling a mechanistic model of the cutting forces with a FE model of the workpiece, including, at each machining step, material removal mechanism. The algorithm follows the milling cycle in the reverse order: starts from the finished part, computes the maximum allowable radial depth of cut, and, adding material accordingly, generates the toolpath until the stock is built. The proposed technique has been experimentally validated, proving its effectiveness.
All Optical Signal Processing Technologies in Optical Fiber Communication

Due to continued growth of internet at starling rate and the introduction of new broadband services, such as cloud computing, IPTV and high-definition media streaming, there is a requirement for flexible bandwidth infrastructure that supports mobility of data at peta-scale. Elastic networking based on gridless spectrum technology is evolving as a favorable solution for the flexible optical networking supportive next generation traffic requirements. Recently, research is centered on a more elastic spectrum provision methodology than the traditional ITU-T grid. The main issue is the requirement for a transmission connect, capable of accommodat-ing and handling a variety of signals with distinct modulation format, baud rate and spectral occupancy. Segmented use of the spectrum could lead to the shortage of availableness of sufficiently extensive spectrum spaces for high bitrate channels, resulting in wavelength contention. On-demand space assignment creates not only deviation from the ideal course but also have spectrum fragmentation, which reduces spectrum resource utilization. This chapter reviewed the recent research development of feasible solutions for the efficient transport of heterogeneous traffic by enhancing the flexibility of the optical layer for performing allocation of network resources as well as implementation of optical node by all optical signal processing in optical fiber communication.
Flexible and Ultrasensitive Piezoelectric Composites Based on Highly (00l)‐Assembled BaTiO3 Microplatelets for Wearable Electronics Application

Piezoelectric wearable electronics with flexibility and high sensitivity have received increasing attention in the fields of health monitoring, flexible robots, and artificial intelligence. Here, a flexible organic–inorganic hybrid composite for wearable electronics application based on (00l)‐aligned BaTiO3 (BT) single‐crystal microplatelets is prepared by layer‐by‐layer self‐assembly technology. For the polyvinylidene fluoride‐trifluoroethylene (P(VDF‐TrFE))/BT single‐crystal microplatelets composite film, the sensitivity is nearly 20 times higher than that of its counterparts of P(VDF‐TrFE)/BT microparticles composite film and pure P(VDF‐TrFE) film. The orderly alignment of BT microplatelets also has been found advantageous to the strength of the composite film. The tensile strength is up to 204.3 MPa even at a high inorganic phase content of 53.8 wt% in P(VDF‐TrFE)/BT single‐crystal microplatelets composite film, which is four times that of pure P(VDF‐TrFE) film. Moreover, the flexible piezoelectric wearable device based on P(VDF‐TrFE)/BT single‐crystal microplatelets film effectively provides detailed information for monitoring human activities such as pronunciation, frequency, and waveform of pulse beating, and motion states. This high sensitivity, high strength, and flexible piezoelectric composite provides much potential on the applications of wearable equipments and health monitoring devices.

SEXUAL MATURATION EFFECT ON PHYSICAL FITNESS IN GIRLS: A LONGITUDINAL STUDY

The purpose of the present longitudinal study was to find associations between sexual maturation dynamics and improvement in performance of fitness tests. 34 11- to 13- year-old girls performed standing long jump, 20 m dash, shuttle run 4 x is related to 9 m, trunk forward flexion, squats in 30 s, sit-ups in 30 s, and Cooper 12-min running test at the beginning of observation, a year later, and two years later. Sexual maturation was assessed with the aid of breast development stages. When during a year girls transferred from the sexual maturation stage 2 to the stage 3, standing long jump results improved significantly. Transfer from the stage 4 to the stage 5 associated with the improvement of the trunk forward flexion.
Effects of Mo content on the microstructural and mechanical properties of as-cast Ti-Mo alloys

The effects of Mo content on the mechanical and microstructural properties of as-cast Ti-10Mo wt. % and Ti-15Mo wt. % alloys were measured in order to evaluate their possible use in biomedical applications. The microstructure and phase analysis of as-cast specimens were studied using an optical microscopy and X-ray diffraction (XRD). The micro-Vickers hardness properties of the alloys were examined using Vickers equipment and the elastic modulus was determined using the tensile test. Results indicated that the Mo content influenced the structure-property relationship. The relative density increased significantly with the addition of Mo, the optical microscopy results showed that CP Ti was characterised with an α’-phase lamellar structure and with the addition of Mo, the microstructure composed of β phase with equiaxed grains of different sizes with sub-grain boundaries were observed. The measured XRD patterns showed that the CP Ti consisted of α’-phase and with the addition of Mo, the resultant alloys consisted of the β-phase. The micro-Vickers hardness and elastic modulus increased significantly after the addition of 10 wt. % Mo and then decreased significantly when the Mo content was raised to15 wt. %.
Transverse Oscillations of a Cantilever Rod of Rectangular Cross Section and Variable Thickness

A numerical-analytical algorithm for calculating (a type of accelerated convergence method) of eigenvalues and modes of transverse vibrations of a rod of variable cross-section is proposed. The algorithm is implemented as a software package in the Maple symbolic computations language. The use of the package was demonstrated by the example of solving problems of determining the eigen forms and natural frequencies of rods with different dependences of the cross section on the longitudinal distance.
Minimally Invasive Allograft Lateral Ankle Ligament Reconstruction

Chronic lateral ankle ligament laxity can be associated with symptoms related to ankle instability and impaired ankle function and may contribute to accelerating posttraumatic degeneration in the ankle joint. Attenuation or failure of previously repaired ligaments in case of recurrent laxity requires augmentation with autograft or allograft as local tissue is frequently of insufficient quality. Furthermore, failed surgical repair may be associated with previous surgical scars and compromised local skin and subcutaneous tissues. Minimally invasive reconstruction of lateral ankle ligaments is an attractive option that avoids long exposures and scars and the risks for wound or flap failure, especially in patients with previous scars or poor soft tissues. Availability of interference screws precludes the need for making bone tunnels to secure the graft to bone and makes the percutaneous and minimally invasive reconstruction feasible.

Micro-OBIC allows to get an Optical Beam Induced Current (OBIC) signal with a microscopic spatial resolution. We used micro-OBIC to characterize peripheral protection such as MESA, JTE or JTE in high voltage SiC device.
Role of Extreme Precipitation and Initial Hydrologic Conditions on Floods in Godavari River Basin, India

Floods are the most frequent natural calamity in India. The Godavari river basin (GRB) witnessed several floods in the past 50 years. Notwithstanding the large damage and economic loss, the role of extreme precipitation and antecedent moisture conditions on floods in the GRB remains unexplored. Using the observations and the well‐calibrated Variable Infiltration Capacity model, we estimate the changes in the extreme precipitation and floods in the observed (1955–2016) and projected future (2071–2100) climate in the GRB. We evaluate the role of initial hydrologic conditions and extreme precipitation on floods in both observed and projected future climate. We find a statistically significant increase in annual maximum precipitation for the catchments upstream of four gage stations during the 1955–2016 period. However, the rise in annual maximum streamflow at all the four gage stations in GRB was not statistically significant. The probability of floods driven by extreme precipitation (PFEP) varies between 0.55 and 0.7 at the four gage stations of the GRB, which declines with the size of the basins. More than 80% of extreme precipitation events that cause floods occur on wet antecedent moisture conditions at all the four locations in the GRB. The frequency of extreme precipitation events is projected to rise by two folds or more (under RCP 8.5) in the future (2071–2100) at all four locations. However, the increased frequency of floods under the future climate will largely be driven by the substantial rise in the extreme precipitation events rather than wet antecedent moisture conditions.
Cervical vertebral maturation as a valid predictor of growth

Cervical Vertebral Maturation as a Valid Predictor of Growth S. HOSNI* J. E. HARRISON and G. BURNSIDE (School of Dentistry, The University of Liverpool, UK) Objectives: The primary objective was to assess if a correlation exists between CVM and statural height growth velocity. The secondary objective was to assess if a correlation exists between CVM and mandibular growth velocity. Design/Setting: A prospective longitudinal study undertaken at Liverpool University. Subjects: Participants were aged between 8-18 years, of either gender and enrolled from the orthodontic waiting list at Liverpool University Dental Hospital. Methods: Standing height was measured every 6 weeks with subjects barefoot and in natural head position. Lateral cephalograms were taken at the start of treatment, on completing functional appliance therapy and prior to debond. Mandibular growth was assessed using the area of the triangle condylion-gnathion-gonion. Intra- and inter-observer reliability of CVM staging, cephalometric and statural height measurements were assessed using Cohen’s weighted kappa, intra-class correlation coefficient, and Bland and Altman plots respectively. ANOVA was used to test for statistically significant differences between the CVM stages. Results: 108 participants were included for analysis. The peak in statural height growth velocity occurred at CVM stage 3 (P=0.001). The peak in mandibular growth occurred at CVM stage 3, although this was not statistically significant. Conclusions: The findings of this study demonstrate that CVM staging is valid for identifying the pubertal peak in statural height. The peak in mandibular growth as assessed by the triangle Co-Go-Gn occurred at CVM Stage 3, but this was not statistically significant. Ethical approval was granted from Liverpool East Research Ethics Committee on 30th October 2013 with reference number 13/NW/0408 and protocol number UoL000751.
Revised Standards for Reporting Inventions in Clinical Trials of Acupuncture (STRICTA): Extending the CONSORT Statement

Objectives and Methods: The Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA) were published in five journals in 2001 and 2002. These guidelines, in the form of a checklist and explanations for use by authors and journal editors, were designed to improve reporting of acupuncture trials, particularly the interventions, thereby facilitating their interpretation and replication. Subsequent reviews of the application and impact of STRICTA have highlighted the value of STRICTA, as well as the need for improvements and revision. To manage the revision process a collaboration between the STRICTA Group, the CONSORT Group, and the Chinese Cochrane Center was developed in 2008. An expert panel with 47 participants was convened that provided electronic feedback on a revised draft of the checklist was convened. At a subsequent face-to-face meeting in Freiburg, a group of 21 participants further revised the STRICTA checklist and planned its dissemination. Results: The new STRICTA checklist, which is an official extension of CONSORT, includes six items and 17 sub-items. These set out reporting guidelines for the acupuncture rationale, the details of needling, the treatment regimen, other components of treatment, the practitioner’s background, and the control or comparator interventions. In addition, and as part of this revision process, the explanation for each item has been elaborated, and examples of good reporting for each item have been provided. In addition, the word “controlled” in STRICTA is replaced by “clinical” to indicate that STRICTA is applicable to a broad range of clinical evaluation designs, including uncontrolled outcome studies and case reports. Conclusion: The revised STRICTA, in conjunction with both the main CONSORT statement and an extension for nonpharmacologic treatment, is intended to raise the quality of reporting of clinical trials of acupuncture.
Material Selection of a Natural Fibre Reinforced Polymer Composites using an Analytical Approach

Material selection has become a critical part of design for engineers, due to availability of diverse choice of materials that have similar properties and meet the product design specification. Implementation of statistical analysis alone makes it difficult to identify the ideal composition of the final composite. An integrated approach between statistical model and micromechanical model is desired. In this paper, resultant natural fibre and polymer matrix from previous study is used to estimate the mechanical properties such as density, Young’s modulus and tensile strength. Four levels of fibre loading are used to compare the optimum natural fibre reinforced polymer composite (NFRPC). The result from this analytical approach revealed that kenaf/polystyrene (PS) with 40% fibre loading is the ideal composite in automotive component application. It was found that the ideal composite score is 1.156 g/cm3, 24.2 GPa and 413.4 MPa for density, Young’s modulus and tensile strength, respectively. A suggestion to increase the properties on Young’s modulus are also presented. This work proves that the statistical model is well incorporated with the analytical approach to choose the correct composite to use in automotive application.
Balancing Priorities: British Bangladeshi Mothers' Perspectives on Functional Independence for their Disabled Children

Introduction: In Western cultures, functional independence is a highly valued concept. It is often utilized as an end goal by occupational therapists working with disabled children. However, little is known about how families from non-Western backgrounds view this concept. Research indicates that professionals frequently use their own understanding of independence to guide input. Without understanding non-Western parents' perspectives on functional independence, occupational therapists are at risk of providing inappropriate and irrelevant intervention. Aim: To understand British Bangladeshi mothers' perspectives on developing functional independence with their disabled children. Method: Semi-structured interviews with ten Bangladeshi mothers and a focus group of Bangladeshi professionals. Thematic data analysis was used to identify key themes from the participants' narratives. Results: Four key themes emerged: developing functional independence in typically developing children; importance of functional independence for disabled children; functional independence versus good care; and functional independence versus safety and protection. Conclusion: British Bangladeshi mothers want functional independence for their disabled children. However, this desire competes with other parenting values of ‘providing good care’ and ‘safety/protection’. The mothers balance these priorities but frequently choose care and safety. Understanding parental perspectives on functional independence is an important starting point for occupational therapists in providing culturally congruent care.
Modelling Droplet Heat and Mass Transfer in Aero-Engine Bearing Chambers

The oil inside aeroengine bearing chambers can be found in many forms, including droplets which interact with the core airflow. The ability to model such bearing chambers computationally is desirable and thus a better understanding of the evaporation process of oil droplets is of great interest. Previous studies have analyzed the flow of isothermal droplets in bearing chambers. However, further investigation is needed into the heating of droplets in the highly rotating core region. This will enable designers to evaluate the behavior of droplets in a chamber and the likelihood that they will evaporate. The aim of this research is to analyze the oil droplet evaporation process under aeroengine bearing chamber representative conditions. An ultimate goal is the ability to predict the oil-air heat and mass transfer in the core flow region, as well as to develop an understanding of the flow inside a droplet, and how this affects evaporation. This latter is important as it has not been studied before. This paper presents the results of a numerical study of the evaporation process of a single droplet under bearing chamber temperature and air flow conditions. The two-phase flow is simulated using ANSYS Fluent with the volume of fluid approach and the evaporation process with the “D−square law”. First, the modelling approach is validated against previous experimental and numerical analysis of fuel droplets in an air flow with heat transfer. The simulation results were in excellent agreement with a benchmarking data set. The validated approach is then applied for investigation to smaller, bearing chamber representative droplets of an oil base stock used in jet engines. The oil evaporation rate was quantified as well as the evolution of droplet diameter, which revealed the effect of different air velocities and temperatures on the droplet. The extent to which evaporation rate increased with air velocity and temperature is quantified. It is concluded that droplets of initial diameters less than 200μm that remain in the chamber core region for more than 0.3s are likely to evaporate completely. This study allows us to estimate droplet heat and mass transfer and the associated phase change in a bearing chamber. It also provides best practice to predict the performance of small droplets under the effects of high temperature and velocity convective air flows. In future work this methodology will be applied in simulations in a representative bearing chamber to predict how the cooling process is affected by oil evaporation.
Comparison of soil moisture products from microwave remote sensing, land model, and reanalysis using global ground observations

High‐quality soil moisture (SM) datasets are in great demand for climate, hydrology, and other fields, but detailed evaluation of SM products from various sources is scarce. Thus, using 670 SM stations worldwide, we evaluated and compared SM products from microwave remote sensing [Advanced Microwave Scanning Radiometer for the Earth Observing System (AMSR‐E) (C‐ and X‐bands) and European Space Agency's Climate Change Initiative (ESA CCI)], land surface model [Global Land Data Assimilation System (GLDAS)], and reanalysis data [ECMWF Re‐Analysis‐Interim (ERA‐Interim) and National Centers for Environmental Prediction (NCEP)] under different time scales and various climates and land covers. We find that: (a) ESA CCI and GLDAS have the closest values to the in situ SM on the annual scale, whereas others overestimate the SM; ERA‐Interim (averaged R = 0.58) and ESA CCI (averaged R = 0.54) correlate best with the in situ data, while GLDAS performs worst. (b) Overall, the deviations of each product vary in seasons. ESA CCI and ERA‐Interim products are closer to the in situ SM at seasonal scales, and AMSR‐E and NCEP perform worst in December–February and June–August, respectively. (c) Except for NCEP and ERA‐Interim, others can well reflect the intermonthly variation of the in situ SM. (d) Under various climates and land covers, AMSR‐E products are less effective in cold climates, whereas GLDAS and NCEP products perform poorly in arid or temperate and dry climates. Moreover, the Bias and R of each SM product differ obviously under different forest types, especially the AMSR‐E products. In summary, SM from ESA CCI is the best, followed by ERA‐Interim product, and precipitation is an important auxiliary data for selecting high‐quality SM stations and improving the accuracy of SM from GLDAS. These results can provide a reference for improving the accuracy of the above SM products.
Aspects Relating to Mechanism of the Capsaicinoids Biosynthesis

Capsaicin, the main component of the hot pepper, is the most common natural product, being represented by over 16000 records in SciFinder data base and also mentioned in Webster English dictionary. Capsaicin is a drug, confirmed by the almost 1000 patents covering the use of the original product, synthetic analogues and the oleoresin from pepper. Comments proving aspects of capsaicin’s biomedical relevance are shown in scientific literature. Suzuki and Iwai’s information of Chemistry, Biochemistry, distribution and ecological aspects of capsaicin remained unknown, still, for two more decades. The taxonomy of Capsicum spp. (Solanaceae) type is also controversial.
Identificação do cronótipo de membros de uma equipe de enfermagem que trabalham nos turnos diurno e noturno

In this work, the objective was to detect chronotypes of healthcare workers of 6h and 12h shift periods and to check whether their working time would correspond to the part of the day that the workers would be on alert or sleepiness. To obtain the data, we have used the Horne and Ostberg (1976) questionnaire. The results reveal that a group identified as moderately matutinal did not present a fit related to the work period. The literature shows that workpeople who have inverted biological clocks suffer the effects from the fatigue and are more susceptible to accidents. Considering that their working periods demand great responsibility, it is possible to evaluate the importance of the study related to the biological rhythm, concerning the impact in health and in the quality of life, the patient’ assistance excellence, as well as at the institutions that hire those workpeople.
