Active sensors for load and damage monitoring in wind turbine blade : a hybrid manufacturing technique

Wind blades are growing in size to harness more energy and are being placed in harsh areas both onshore and offshore. Larger wind blades imply higher loads on the turbine and drivetrain. Monitoring and controlling these loads become critical for safe and profitable operations. Currently fiber optic based sensors are the most popular choice for load monitoring but require expensive and bulky interrogation equipment. The newly developed triboluminescent (TL)-based C-shaped ITOFPress sensor has the ability to monitor dynamic continuous applied loads consistently over cycles. In addition, another TL-based sensor called ITOF sensor has the ability to monitor damage in composite. These sensors do not require any external power source at the sensing location nor for transmitting signals. C-shaped ITOFPress sensor is installed in a hybrid composite blade with the purpose of load sensing, while ITOF sensor is embedded into the composite to monitor damage due to impacts. An experimental setup is designed and established in order to perform both dynamic mechanical loading and impact tests. This paper presents the results of both tests on a lab-sized hybrid composite blade to evaluate the damage and load sensing performance of the novel TL-based sensors.
Unequal Regional Development in Rural Vietnam: Sources of Spatial Disparities and Policy Considerations

In Vietnam, the poor have long been assumed to be the ethnic minorities mostly living in the highlands. After more than two decades of introducing Doi moi1 policy into the economy, along with having enjoyed various improvements in social and economic aspects, the disparities between the majority and ethnic majorities, the lowlands and the highlands, and between regions, still have been widened. This paper aims at examining sources of spatial disparities in rural areas, and exploring the current situation of regional economic development using both development policy review and econometrics approaches. Data from Vietnam Household Living Standard Survey (VHLSS) 2008 was used in the study. The expenditure per capita was employed as the dependent variable to regress with household characteristics and resources in order to obtain the effecting factors. In addition, the regional dummy variables were employed to show the effects from different geographic locations. The results showed that the household characteristics and resources such as education level, perennial land area, water surface area, and the accessibility to infrastructure facilities such as road, electricity and local market had positive effect on the expenditure. Furthermore, the North Central Coastal region showed negative impact on household expenditure. Interestingly, this finding does not absolutely follow the hypothesis and indicates that the economic development strategy and polices should be adjusted to decrease the gap among regions based on their economic advantages for balancing the economic situation of the whole country in the future.
Convection of a van der Waals fluid near the critical point

Convection in a van der Waals fluid, with no-stress and fixed flux boundary conditions is studied. The problem is scaled with the infinite wavelength of the convection cell. A criterium is found that predicts the onset of convection; it contains information from the Rayleigh and Scharzschild criteria over the entire cell. The criterium is evaluated and compared with previous experiments on a similar experiment. Governing equations, boundary conditions, constitutive equation and convection mechanisms are explained.
Beyond deep fakes: Conceptual framework and research agenda for neural rendering of realistic digital faces

Neural rendering (NR) has emerged as a novel technology for the generation and animation of realistic digital human faces. NR is based on machine learning techniques such as generative adversarial networks and is used to infer human face features and their animation from large amounts of (video) training data. NR shot to prominence with the deep fake phenomenon, the malicious and unwanted use of someone’s face for deception or satire. In this paper we demonstrate that the potential uses of NR far outstrip its use for deep fakes. We contrast NR approaches with traditional computer graphics approaches, discuss typical types of NR applications in digital face generation, and derive a conceptual framework for both guiding the design of digital characters, and for classifying existing NR use cases. We conclude with research ideas for studying the potential applications and implications of NR-based digital characters.
Impact force identi fi cation with pseudoinverse method on a lightweight structure for underdetermined , even-determined and overdetermined cases

Force identification using inverse technique is important especially when direct measurement through force transducer is not possible. Considering the effects of impact excitation force on the integrity of a lightweight structure, impact force identification has become the subject of several studies. A methodology utilising Operating Deflection Shape (ODS) analysis, Frequency Response Function (FRF) measurement and pseudo-inverse method to evaluate the dynamic force is presented. A rectangular plate with four ground supports was used as a test rig to simulate the motions of a simple vehicle body. By using the measured responses at remote points that are away from impact locations and measured FRFs of the test rig, unknown force locations and their time histories can be recovered by the proposed method. The performance of this approach in various cases such as under-determined, even-determined and over-determined cases was experimentally demonstrated. Good and bad combinations of response locations were selected based on the condition number of FRF matrix. This force identification method was examined under different response combinations and various numbers of response locations. It shows that in the over-determined case, good combination of response locations (i.e. low average of condition number of FRF matrix) and high number of response locations give the best accuracy of force identification result compared to under-determined and even-determined cases. 2013 Elsevier Ltd.

A Prospective Study of Single Breath Vital Capacity Inhalation Induction with High Concentration of Sevoflurane (Sbvc-Hc) for LMA Insertion in Adults for Short Surgical Cases

Background: Sevoflurane is a new volatile anesthetic agent with rapid induction and recovery. A randomized study was carried to access conditions for LMA insertion using Sevoflurane in 25 ASA I & II patients undergoing short duration surgeries. Subjects and Methods: This prospective study was conducted at Department of Anesthesiology and Critical Care, SVS Medical College and Hospital, Mahabubnagar, Telangana, India. After obtaining the institutional ethics committee and written informed consent from the patients, 25 subjects of either sex were included in this study. Age of the subjects was 18 to 60 years. Patients received injection Fentanyl 1 – 2mcg/kg prior to induction. All patients were pre-oxygenated for 3 min with 100% oxygen using a fresh gas flow of 81/min. All patients received inhalational induction with 8% Sevoflurane and O2 flow at 8 L/min with single vital capacity breathe technique. Loss of verbal contact was considered as the desired endpoint for induction, which was assessed by the response to calling out the patient’s name. Then the time of loss of eyelash reflex and jaw relaxation was assessed by anesthesiologist. After adequate jaw relaxation, LMA insertion was attempted. Results: The mean loss of verbal contact was 65.40±9.67second, while the mean for time for loss of eyelash reflex and jaw relaxation were found to be 81.20±9.39 seconds and 103.20 ±12.07 seconds respectively. The mean time for LMA insertion was 122.00±15.61 and the mean attempts for successful LMA insertion was 1.12±0.33. LMA insertion was easy in 23 cases as against difficult in 2 cases. In 2 cases transient cough and biting were recorded. LMA insertion was excellent and satisfactory in 88.0 and 12 percent. However, the mean heart rate at 5 minute after induction showed a significant fall at 5 minutes after induction. The mean values of SBP, DBP and MAP did not differ significantly at pre and induction. However, a significant decrease in SBP was noticed at 1, 2 and at 5 minutes. Conclusion: Sevoflurane is an smooth inhalation anesthesia with rapid onset with adequate jaw relaxation for insertion of LMA in Adults for short duration surgeries. Sevoflurane has got good hemodynamic profile with lesser complications owing to choice of inhalation agent for insertion of LMA.

Collaborative Governance for Poverty Alleviation: A Systematic Mapping Study2

The study of poverty reduction is very relevant in the 21st century. The rapid development of technology has proven to improve various quality of life but has not been able to solve the problem of poverty in a total scale. On the other hand, the development of public administration science, especially regarding collaborative governance, provides hope for poverty reduction through the active role of various parties. Many experts explain that poverty is a complex problem. Poverty reduction efforts must be carried out in a holistic and participatory manner. Furthermore, there needs to be an active contribution from various parties, namely the government, the private sector and the community. This requires researchers to conduct further studies on how Collaborative Governance can be an alternative solution to solving the problem of poverty. This study aims to delineate the development of Collaborative Governance studies through the Systematic Mapping Study and associate it to the poverty alleviation to obtain the current research position. The study shows that research on Collaborative Governance for Poverty Reduction is included in Social Issues in Community concentration and it has the lowest percentage. The most widely used method in the research concentrated on Collaborative Governance is qualitative, and the publication trend shows a very significant development, especially in 2014-2018. Therefore, research on collaborative governance for poverty alleviation is still very limited and the opportunity to produce variety of renewals is very large.

Length and shape of a lava tube

We study a model of a viscous melted substance flowing in a cold circular tube. As the fluid flows, it cools and solidifies at the tube radius, and we investigate the question ‘how far can the fluid flow and remain liquid? ’ A theoretical solution is derived for the radius of the liquid tube and the temperature profiles in the liquid and the solid. It is shown that if the fluid is maintained at constant flux, the tube can be infinitely long, but if it is maintained at constant pressure difference across the length of the tube, then there is a maximum length which depends on the Peclet number and a dimensionless temperature. The stability of the steadystate profiles are investigated, and it is shown that the linear stability of the tube radius can be determined from the functional relationship between pressure and flux. Numerical simulations are performed to test these predictions.
Process of Production of Bilingual didactic Materials of the national institute of education for the deaf

This paper aims to present the various stages of production of bilingual didactic materials of the National Institute of Education for the Deaf (Instituto Nacional de Educação de Surdos INES), analyzed in their theoretical and technical aspects (preproduction, translation and post-production), with a description of the principles of multimedia learning linked to the conception of bilingual digital objects developed at the Online Education Center (Núcleo de Educação Online NEO). Considering the present shortage of bilingual didactic material available for the education of the deaf, we intend to contribute with the establishment of fundamental quality parameters for this kind of production. In this work, we present 15 stages of the workflow for the production of bilingual didactic materials from NEO, among which we highlight the role played by the translators-interpreters team, who take turns in the role of translator-presenter, translator-supervisor and translator-proofreader. In addition, the fundamental principles of multimedia learning in the development of bilingual didactic materials are emphasized. Thus, we concluded that the references of multimedia learning allied to the guiding principles of the education of the deaf creates a line of development of didactic materials possible, with innovation and interdisciplinary methods, to a deepening of knowledge capable of contributing to the qualitative expansion in the production of bilingual didactic materials in Sign Language/Portuguese Language.
Expression of bcl-2 and the Progression of Human and Rodent Prostatic Cancers 1

The frequency of bcl-2 protein expression was evaluated using immunocytochemical staining during the progression of human and rat prostate cancer from an androgen-sensitive nonmetastatic to an androgen-independent metastatic phenotype. Previous studies (A. S. Shabaik et al., J. Urol. Pathol., 3: 17-27, 1995) demonstrated that 0 of 20 high-grade prostatic intraepithelial neoplasias and only 3 (7%) of 41 pathologically localized stage B human prostatic cancers had detectable bcl-2 staining. In the present study, 5 (17%) of 30 lymph node metastases from pathologically disseminated O 1 disease and 14 (52 %) of 27 bone metastases from pathologically disseminated D 2 disease expressed detectable bcl-2 protein. These data demonstrate that there is a statistically significant (P < 0.05) association between expression of bcl-2 and the progression of human prostatic cancer cells to a metastatic phenotype. Such bcl-2 expression is not absolutely required, however, for either androgen independence or metastatic ability by human prostatic cancer cells. Likewise, within a series of eight distinct Dunning R3327 rat prostatic cancer sublines, which differ widely in their progressional state, there is also a significant association (P < 0.05) between bcl-2 expression and progression (four of six androgen-independent rat sublines expressed bcl-2 protein). Again in this rodent system, bcl-2 expression is not an absolute requirement for either androgen independence or metastatic ability. For example, the androgenindependent highly metastatic Dunning AT-3 subline, while expressing bax protein, does not express bcl-2 protein. If such AT-3 cells are genetically engineered to express bcl-2, these expressing cells are now cross-resistant to a variety of mechanistically diverse noxious insults (e.g., viral infection or exposure to antimetabolites, alkylating agents, or agents which elevate the intracellular free Ca2+). The ability of bcl-2 to inhibit the programmed death of AT-3 cells induced by these agents involves a late step in the death process, since the early induction of expression of a series of genes associated with apoptosis is not impaired by bcl-2 expression. These data demonstrate that the development of androgen independence and/or metastatic ability can be associated with the expression of bcl-2 protein but that bcl-2-independent mechanisms also exist for such progression.
- 2-Enhancing capabilities through credit access : creditworthiness as a signal of trustworthiness

Creditworthiness and trustworthiness are almost synonyms, because the act of conferring a loan has the indirect effect of signaling the trustworthiness of the borrower. We test the creditworthiness/trustworthiness nexus in an investment game experiment on a sample of participants/non-participants in a microfinance program in Argentina and find that trustors give significantly more to (and believe they will receive more from) microfinance borrowers. The firstand second-order beliefs of trustees are also consistent with this picture. Our findings show that MF participants appear more trustworthy. This implies that, if (and only if) the situation of imperfect information on individual characteristics of the experiment applies to real life business relationships, the mere loan provision acts as a reputation enhancing signal increasing the borrower’s attractiveness as a business partner. In this sense we have a channel through which a private financial intermediary contributes to the provision of a public good like information, thereby reducing the adverse consequences of market failures on the creation of economic value.
Does Juan Carlos or Nelson Obtain a Larger Price Cut in the Spanish Housing Market?

Using a unique dataset and a nonparametric decomposition, we determine whether immigrants with native names, immigrants with foreign names, and natives have different outcomes in Spain’s housing market. Results suggest that immigrants with native names achieve greater discounts relative to immigrants with non-Spanish names. As a robustness check, we prove that this is not due to the country of birth. We observe that most of the difference in price across immigrant groups remains unexplained, which may imply some form of discrimination (pure or statistical) against immigrants with non-native names.
Enhanced recovery after surgery (ERAS) and anesthesia

ERAS (Enhanced Recovery After Surgery) is a multimodal approach which aims to optimize perioperative management. ERAS is a combination of changes in preoperative, intraoperative and postoperative care to reduce organ dysfunction and surgical stress response. This concept is managed by multidisciplinary teams that include various areas of expertise to minimize the patient’s surgical stress response, optimize physiological functions, and facilitate healing. In order to further increase these devel-opments in various surgical specialties, protocols have been established on this sub- ject and many health institutions offer their services in this way. With the use of ERAS protocols, perioperative and postoperative complications decreased, patient survival and quality of care improved, and patient satisfaction was significantly increased.
Detection of magnetic particles by magnetoresistive sensors

In this work, we demonstrate the implementation of the micromagnetic equations for the description of ferromagnetic thin films in COMSOL Multiphysics. We apply our model to magnetoresistive sensors consisting of several soft ferromagnetic layers and their response to magnetic particles. The magnetization dynamic of the particles needs to be described in a similar manner, though due to size effects it is possible to reduce the description to a set of ordinary differential equations. The signal will be discussed in respect to the particle position as well as the influence of antiferromagnetic ordering in particle clusters that are within detection range.
First contact in a viscous fluid

Lubrication theory has been successfully applied to many problems in fluid dynamics. For cases where two objects slide past each other, with a thin film of fluid filling the intervening gap, it performs admirably, and its application has formed the basis for many important advancements in engineering. Furthermore, it appears in most undergraduate courses in fluid mechanics (see [1], for example). However, when used to model the coming together of two solid objects separated by a viscous fluid, the predictions of lubrication theory are decidedly unphysical. Consider the simple example of a rigid cylinder settling under gravity towards a rigid, horizontal plane, as illustrated by Figure 1. The thickness of the gap between the cylinder and the plane is denoted by h(x), where x is a horizontal coordinate measured relative to an origin situated at the intersection of the horizontal plane and the axis of symmetry. Under the approximation key to lubrication theory (the so-called ‘lubrication approximation’, which is valid provided that Re 1), we ignore horizontal variations relative to the much faster vertical variations when calculating the horizontal velocity, and assume that the pressure only varies in the horizontal coordinate x. We find that the horizontal velocity has a parabolic profile u(x, z) = − 1 2μ ∂p ∂x z[h(x) − z],
A new triadotypid insect from the Late Triassic of South Africa

Extant odonates (damsel- and dragonflies) represent a small subset of the historical biodiversity of this group. Among their successive stem-groups, the Triadotypomorpha are poorly documented. Herein we describe a new species Reisia rieki from the Molteno Formation (South Africa, Upper Triassic) belonging to this taxon. The comparatively large sample allows a relatively complete description of the wing venation in Triadotypomorpha. We noticed the occurrence of a strongly oblique crossvein located between RA and RP1, a condition documented in some other Pandiscoidalia and which might be of phylogenetic importance. The new species probably inhabited open landscapes and foraged above large water bodies. The documentation of a Gondwanian Triadotypomorpha demonstrates that the group had a worldwide distribution by the Triassic.
1Akinrinola et al edited Final 2 formatted (1) new

This study explored teachers’ knowledge and integration of competency-based practices in schools. One hundred and fifty in-service secondary school teachers were sampled across three African countries using a survey research design. A combination of both closed and open-ended questions was used to elicit responses from respondents via an online system. Responses from the open-ended questions were analysed using thematic analysis, and data received from the structured questions were analysed using percentage distribution. The theoretical lens through which this study was viewed was the Human capital theory and social constructivism theory. Findings revealed that teachers across the three countries have a positive perception of the usage of competency-based approaches but lack professional training and support, which in turn affects the quality of their teaching and assessment practices in classrooms. The implications and recommendations from this study offer teachers as well as education stakeholders in Africa valuable consideration to move beyond the traditional level of assessment and integrate good proxies of academic skills that support learners’ acquisition of 21stcentury skills such as problemsolving, creativity and critical thinking in assessing learners’ competencies.
