Published: November 2017

Resumo Embora a escola esteja inserida em um contexto social dinâmico e envolto em tecnologias, muitos professores de ciências e de química da educação básica continuam seguindo o modelo de transmissão/recepção de informações. Com a intenção de analisar mudanças no discurso e no entendimento sobre o papel do professor em sala de aula, a partir da vivência em projeto de imersão na docência centrado no planejamento e desenvolvimento de aulas temáticas e na avaliação compartilhada das próprias aulas, desenvolvemos este trabalho. Para isso, analisamos as aulas de dois professores em formação inseridos nesse projeto. Usamos a filmagem das aulas e uma entrevista semiestruturada como instrumentos de coleta de dados. A análise se deu, principalmente, por meio do discurso usado pelos professores e pela capacidade de envolver os estudantes na dinâmica das aulas. Percebemos que o envolvimento com aulas temáticas foi importante para esses professores. Em adição, a avaliação compartilhada das aulas se mostrou fundamental para melhorar o entendimento sobre o papel do professor. Os dados encontrados nos levam a acreditar que essa melhora irá se refletir na prática, quando esses professores assumirem a docência.
Water retention and thermal conductivity of a natural unsaturated loess
Authors: Nguyen V. T. , Heindl H. , Pereira J. M. , Tang A. M. , Frost J. D.
Published: November 2017

Loess covers large portions of Earth's surface. Loess deposits are typically composed of silt with clay and fine sand particles and usually reach a few meters in thickness. Thermal conductivity of loess varies over a relatively large range from 0·07 to 2 W/(m.K), depending on the particle composition, soil texture and also moisture content. In this study, intact loess was sampled at shallow depth (1 m) in Northern France. Suction, volumetric moisture content and thermal conductivity of soil were measured simultaneously during the application of wetting/drying cycles to the sample. The results show that the volumetric moisture content significantly influences the soil thermal conductivity. As is the case for the water-retention curve, a hysteresis loop can be observed when plotting the thermal conductivity against suction. However, no hysteresis appears when the thermal conductivity is plotted as a function of the degree of saturation.

For promoting the successful aging of elderly residents of Chang Gung Silver Village in Taiwan, five interactive exergames were developed to promote the well-being of the elderly. The exergames included both physical games and cognitive games and were implemented using various computer-based technologies in the Chang Gung Silver Village. The exergames were trialed by 39 elderly residents (15 male, 24 female; mean age 79.5 ± 17.5 years) of Chang Gung Silver Village. Following the trials, the participants were requested to complete a Technology Acceptance Model 2 (TAM2) questionnaire. The results showed that the perceived playfulness and perceived usefulness of the exergames were significantly related to the users’ usage behavior and intention to use for both the physical games and the cognitive games. However, a relationship between the output quality of the game and the usage behavior was apparent only in the case of the cognitive exergames. Finally, the impact of social influence on the intention to use and the usage behavior was more pronounced for the physical exergames. Overall, the results revealed that the acceptance of exergames by the elderly depends not so much on the awareness of fun in using the game, but the perceived usefulness of the related physical and cognitive abilities.

The royal python (Python regius) is commonly bred in captivity. To have a successful breeding, accurate monitoring of the reproductive activity is necessary. The use of non-invasive monitoring methods in exotics is important in order to minimize stress. For this purpose, ultrasound has been anecdotally used to monitor royal python reproductive activity. However, there is limited information regarding the reproductive cycle of this species. The aim of the present study is to monitor the female reproductive cycle of the royal python using ultrasonography and gonadal steroid metabolite measurements in the faeces. The reproductive activity of one hundred twenty-nine adult female P. regius was examined during two consecutive years. We performed brief scans on non-anaesthetized snakes using a portable ultrasound system and a 10-12 MHz linear array transducer (MyLab™ 30 Gold, Esaote). Ultrasound features, dimension and echogenicity of the reproductive structures were determined. During the second reproductive cycle, the hormonal profiles of 30 animals were also evaluated, with a monthly collection of faecal samples. These samples were classified according to reproductive stage, and the mean faecal progesterone and 17β-estradiol levels were calculated using the results from an enzyme-linked immunosorbent assay (ELISA). Progesterone levels increased during the reproductive cycle. estradiol levels showed greater variability, although they appeared to increase before coupling when compared to the levels between coupling and egg laying. The present study suggests that it is possible to identify different phases in the female royal python reproductive cycle: anovulatory phase, transition, folliculogenesis and embryogenesis. Ultrasound is also useful for identifying follicular regression or slugs. Gonadal steroid metabolite measurements from the faeces could help integrate the reproductive information. The use of ultrasonography in addition with the steroid metabolite measurement in the faeces gives an accurate picture of ovarian activity in captive adult female royal pythons.
Our experience in visual functions' improvement in patiens with “wet” age-related macular degeneration at switching from one anti-VEGF agent to another
Authors: Korotkikh Sergey A. , Bobykin Evgeniy V.
Published: November 2017

Purpose. To assess mean changes in visual acuity, central retinal thickness and macular volume as well as to determine the duration of clinical choroidal neovascularization inactivity after single aflibercept injection in neovascular age-related macular degeneration (nAMD) patients switched from ranibizumab (preliminary date). Methods. Open-label prospective study. The study enrolled 23 patients with nAMD previously treated with ranibizumab.

Results. Mean age of patients was 70.5 years, 16 were women. Mean number of ranibizumab injections given prior to switching to aflibercept was 8.7. After single aflibercept inravitreal injection mean visual acuity has significantly improved from 0.40 to 0.47 Snellen chart. Mean central retinal thickness has significantly reduced from 323.1 to 246.9 m and mean macular volume has significantly reduced from 7.71 to 6.74 mm3. Duration of choroidal neovascularization (CNV) inactivity was 2.91 months.

Conclusion. Single aflibercept intravitreal injection has resulted in significant visual gain as well as in significant central retinal thickness (CRT) and macular volume reduction. This provides evidence of aflibecept efficacy in nAMD patients previously treated with anti-VEGF. Duration of CNV inactivity provides clinical data supporting aflibercept injection every 8 weeks in nAMD patients.

Towards an effective freeware resource for music composition in the primary classroom
Authors: Hart Adam
Published: November 2017

This paper presents an ongoing project to develop a freeware resource for music composition in the primary classroom. The national curriculum for music at Key Stages 1 and 2 calls for students to 'compose music for a range of purposes using the inter-related dimensions of music', a
challenging aim that demands significant guidance, support and resources. With cuts to school funding and prioritization of core subjects, teachers and researchers are faced with finding solutions to ensure the provision of a quality music education. As part of a wider research project funded
by the Arts and Humanities Research Council, Graphick Score has been continuously developed and used for music composition lessons in primary schools throughout the north-west of England. This paper examines the present effectiveness, potential and limitations of this resource, as well as
the further need for research and technological solutions to make a creative and meaningful music education a part of the school life of all children.

Published: November 2017

Few institutionalized examples exist wherein Indigenous communities have participated in the co-development of ethics initiatives. This article explores one such process—the Memorandum of Understanding (MOU). A MOU is a document created between institutional and community research partners to outline project guidelines. Based on Canadian MOUs developed between 1980 and 2016, this research has four objectives; (a) to describe current trends of MOU use and recognition in research; (b) to describe the challenges of collaborative research and how MOUs might mitigate them; (c) to understand if a standard MOU is feasible; and (d) to offer policy suggesting for implementing MOUs. Local MOUs mark a way for engaging in good research practices that actually benefit the involved community.

Published: November 2017

Background and Purpose:The purpose of our study was to assess the effects of self-knee massage with ginger oil on pain and daily living activities in patients with knee osteoarthritis.Methods:Participants (N= 68) were asked about their sociodemographic characteristics, pain level in the last week using the Visual Analog Scale (VAS), and functionality in activities of daily living with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Standard treatment prescribed by a physician was given to the patients with osteoarthritis. In addition to the standard treatment, self-knee massage with ginger oil twice a week was recommended to the intervention group (n= 34). At the end of the first and fifth week, participants in both groups were assessed regarding pain and functional state.Results:The mean VAS Pain scores of the intervention group were significantly lower at the end of the first and fifth weeks (p< .05). The mean total scores and mean Function subscale scores of the WOMAC were significantly lower in massage group in the first- and fifth-week assessments (p< .05).Implications for Practice:Self-massage of the knee with ginger oil may be used as a complementary method to standard medical treatment. Nurses can easily train patients and their caregivers on knee massage, and the intervention can be implemented by patients at home without any restrictions on location.
Población y crecimiento económico. Una versión mejorada del modelo de Solow
Authors: Brida Juan Gabriel
Published: November 2017

Una de las hipótesis tradicionales en teoría del crecimiento económico es que la fuerza de trabajo crece exponencialmente. Esta no es una hipótesis sostenible pues implica que la población del planeta puede ser arbitrariamente grande. En este artículo mejoramos el modelo de Solow de introducir una ley de crecimiento poblacional que verifique las propiedades más importantes observadas en el crecimiento de la población humana: i) la población es creciente y acotada y ii) la tasa de crecimiento de la población decrece a 0 cuando el tiempo tiende al infinito. El resultado principal del trabajo es un teorema en el que se demuestra que el modelo es asintóticamente estable y que el capital per capita tiende a un valor constante.

Según el esquema del resultado de imposibilidad de Arrow, la información proveniente de comparaciones interpersonales no puede ser usada para construir reglas de elección colectiva. Por otro lado, mediante el uso de funciones de utilidad y la comparación de diversos aspectos de las mediciones, entre todos los individuos, se han logrado caracterizar diversas reglas no dictatoriales que, además, se usan empíricamente. En este trabajo estudiamos un esquema general para realizar comparaciones interpersonales con utilidades cardinales. Caracterizamos un concepto de comparación parcial que admite, como extremos, los casos de comparaciones totales o la ausencia de las mismas entre los individuos. Nuestro concepto sirve de base para proponer una clasificación de todos los órdenes de bienestar social, caracterizando cada uno con supuestos estándar y el tipo de comparación interpersonal admitida.

DMA results showed the immiscibility of blends above a certain composition. Colorimetry results give an insight into Yellowness index values of various blends with different compositions. Similarly, other improvements and optimization was observed and recorded for different batches while studying their thermal properties.
On Some New Properties of the Fundamental Solution to the Multi-Dimensional Space- and Time-Fractional Diffusion-Wave Equatio
Authors: Luchko Yuri
Published: November 2017

In this paper, some new properties of the fundamental solution to the multi-dimensional space- and time-fractional diffusion-wave equation are deduced. We start with the Mellin-Barnes representation of the fundamental solution that was derived in the previous publications of the author. The Mellin-Barnes integral is used to get two new representations of the fundamental solution in form of the Mellin convolution of the special functions of the Wright type. Moreover, some new closed form formulas for particular cases of the fundamental solution are derived. In particular, we solve an open problem of representation of the fundamental solution to the two-dimensional neutral-fractional diffusion-wave equation in terms of the known special functions.

We previously reported the 10 to 13-year follow-up results for 104 total hip replacements with the Zweymüller Alloclassic stem and a threaded cup in 94 patients. The present study is a clinical and radiographic outcome update after a minimum follow-up of 25 years. Four patients (4 hips) were lost and 46 patients (50 hips) died, leaving 44 patients (50 hips) available for follow-up. Since our previous report, 7 cups and 2 stems were revised. At 20 years, the probability of survival of any component was 84.1% (95% confidence interval [CI], 73.91% to 94.29%) and the cumulative probability of not having stem loosening was 95.9% (95% CI, 95.51% to 96.29%). We observed proximal femoral osteolysis in 15 hips (30%), cortical hypertrophy in 21 hips (42%), and proximal femoral osteopenia in 30 hips (60%). The Zweymüller Alloclassic stem continues to provide excellent results after extended follow-up.

The physical of paddy and milled rice qualities, physicochemical properties and the functional properties of milled rice were analyzed to study the grain characteristics of four local paddy varieties derived from West Kalimantan. The study was conducted at Post Harvest Grain Quality Laboratory, Indonesian Center for Rice Research in 2013. Method used for physical and milling quality properties followed IRRI method. Functional characteristic was analyzed using LC-MS. The observations were done in six replications. The data was analyzed for the correlation among characters. Significant correlation between characters was further analysed for regression equation. The shapes of grains of local rice varieties were slim to medium. There was correlation between paddy moisture content and head rice percentage, between damaged grain and paddy density, between yield of brown rice and yield of milled rice, and percentage of head rice, between percentage of head rice and yield of milled rice, and between empty grain and broken grain. The functional character relationship showed that Cyanidin 3 Glucosidase (C3G) content of brown rice influenced the C3G content of milled rice. “Sanik” red rice, “Beliah” purple rice and “Balik” black rice may be useful to be used as parent for crossing in the breeding program for functional rice varieties, due to their good quality of milled rice and their high content of C3G. The C3G is considered as anticancer, antioxidant, anti coronaria heart disease and it improves fat profiles in the blood. Therefore, colored rice is recommended to be consumed in a form of brown rice or milled rice with 80% degree milling to retain the C3G content which is beneficial for the human health.

Characterization of mutant wheat (Triticum aestivum L.) lines is a step on the breeding program to determine the beneficial characters for increasing the productivity in tropical lowland. The aim of this research was to obtain information on the variability of morphological, anatomical, and physiological characters that could be used as selection criteria and to obtain adaptive mutant lines of “Alibey” in tropical low altitude land. Research was conducted at the Experimental Farm of SEAMEO-BIOTROP in Bogor 250 m above sea level, from April to December 2013. Mutant lines of “Alibey” consisted of 16 M3 mutants resulted from treatments of EMS. LC50 of “Alibey” at 0.1% EMS for 60 minutes. Results showed that the mutant lines changed their morphological traits significantly, as indicated by the four characters i.e. long stem panicle (8 mutants), grain weight/panicle (1 mutant), weight of 100 seeds (4 mutants) and seed weight/plant (9 mutants). However, the mutant had no significant effect on the nine other characters, including: time of flowering, days to maturing, panicle length, plant height, number of tillers, panicle number, and leaf area. Anatomical characters namely leaf thickness and stomata size showed different values between “Alibey” mutant (AB-0.1.60-1-7-1) and the original Alibey. For the physiological characters there were significant differences among mutants with respect to the amount of proline and glucose levels. Proline level in the control plant was 4.15 ug/g BB, while that in mutant “AB-0.1.60-3-16-1” was 263.47 µg/g BB, and that in “AB-0.1.60-3-3-2” was 235.90 µ/g BB. Likewise, glucose level in control was 132.88 mg/ml, while in mutant “AB-0.1.60-3-16-1” was 181.48 mg/ml, and that in “AB-0.1.60-3-3-2” was 287.41 mg/ml. “Alibey” mutants should be selected based on two characters i.e. stem panicle length and seed weight/plant. Correlation analysis between panicle number and all other characters were not significant. Plant height significantly affected the grain weight/panicle and the grain weight/plant. It is expected that some of the mutants are adaptable to the tropical lowlands, so that the diversity of wheat germplasm in Indonesia is increased.

The objective of this study was to obtain the most effective herbicide for weed control on soybean planted under saturated culture in the tidal swamp land. Research was conducted in tidal swamp land at Banyu Urip village, Tanjung Lago districs, Banyuasin, South Sumatra Province, from July to December 2013, using a randomized block design consisted, of the eight treatments, with three replications. The treatments were: control (P0), manual weeding 4 weeks after planting (P1), paraquat 2 l/ha 4 weeks after planting (P2), glyphosate 3 l/ha 4 after planting (P3), oxyfluorfen 2 l/ha 3 days before planting (P4), oxyfluorfen 3 days before planting 2 l/ha followed application of paraquat 4 weeks after planting 2 l/ha (P5), oxyfluorfen 3 days before planting 2 l/ha followed application of glyphosate 4 weeks after planting 3 l/ha (P6), penoxulam 1 l/ha 2 weeks after planting (P7). Results showed that herbicide paraquat effectively suppressed total dry weight of weeds at 4, 6, and 8 weeks after planting. Cyperus iria was the most dominant weed in the field, with Sum Dominance Ratio 37.7%. The highest soybean productivity was 3.7 t/ha obtained from glyphosate treatment. Pre-emergence herbicide applications should be done prior to soybean planting and the post-emergence herbicide application must be done carefully by using nozzle lid to prevent toxicity to the crop plants.

Black rice is a local rice variety with some advantages and weaknesses. The desirable character of black rice is its high anthocyanin content, while the weaknesses are late maturing, tall plant stature and low grain yield. Crosses were made between two parents aimed to recombine the superior traits. The effectiveness and efficiency of selection would be determined by the magnitude of the heritability of traits and the selection progress. This study was aimed to determine the heritability estimates in a broad sense and the genetic advance of agronomic characters of F2 generation, from crosses of local black rice and high yielding variety of white rice. The experiment was conducted in Padasan, Pakembinangun, Pakem, Sleman, Yogyakarta from January to May 2013. The F2 population derived from crosses of black rice x white rice, with the morphological traits of hairless black rice (S) crossed with Situbagendit (G) white rice, Cempo ireng (C) with Situbagendit (G) and Cempo ireng (C) with Inpari 6 (I). The F2 plants population were planted without replication. Genetic parameters estimated were calculated for broad sense heritability and genetic advance from selection. Results showed that the F2 population had high broad sense heritability estimates for all characters observed, including: plant height, flag leaf length, number of productive tillers, panicle length, number of filled grains per panicle, number of empty grains per panicle, maturity and rice color, in the three F2 populations obtained from crosses of S x G, C x G and C x I. Only the plant height of S x G cross had a medium broad sense heritability estimate. The large heritability estimates indicated that the respective character was controlled by genetic factor more than environmental ones. High genetic advance would be obtained in the flag leaf length, number of productive tillers, panicle length, number of filled grains/panicle, number of empty grains/panicle and rice color from S x G, C x G and C x I crosses. Genetic advance of plant height was medium (at S x G and C x I crosses) to high (C x G crosses). The maturity trait had low genetic advance on cross S x G; C x G; and Cx I. The high value of genetic advance of character would suggest that selection on the character’s appearance would be successful.
Entanglement Entropy in Lifshitz Theories
Authors: He Temple , Magan Javier , Vandoren Stefan
Published: November 2017

We discuss and compute entanglement entropy (EE) in (1+1)-dimensional
free Lifshitz scalar field theories with arbitrary dynamical exponents.
We consider both the subinterval and periodic sublattices in the
discretized theory as subsystems. In both cases, we are able to
analytically demonstrate that the EE grows linearly as a function of the
dynamical exponent. Furthermore, for the subinterval case, we determine
that as the dynamical exponent increases, there is a crossover from an
area law to a volume law. Lastly, we deform Lifshitz field theories with
certain relevant operators and show that the EE decreases from the
ultraviolet to the infrared fixed point, giving evidence for a possible
cc-theorem
for deformed Lifshitz theories.

Published: November 2017

Development of new effective drugs for therapy of metastatic melanoma (BRAF/MEK inhibitors, PD1/CTLA4 blockers) requires additional studies of the optimal sequence of their use. But in many cases the duration of the effect of these medicinal products is limited by time even in their sequential use. This literature review considers a possibility of repeated indication of BRAF/ MEK inhibitors after progression on them in various clinical settings. The potential use of such approach is illustrated by two own clinical observations.

Therapy of CRPC is one of the most difficult problems in oncourology. Until now the optimal consequence of use of drugs in CRPC is not determined.

Study objective: evaluation of effectiveness  of sequential  therapeutic schemes  in progression of m-CRPC: cytotoxic (Docetaxel) or second-line hormonal therapy (Abiraterone) after previous treatment by an analogue of prolonged action somatostatin (Octreotide-depo) and without it.

Materials and methods: the study design included 4 groups of patients (170 subjects). The first two groups included patients who received initial therapy by Octreotide-Depo 30 mg before chemotherapy and second line hormone therapy, compared to two groups of primary chemical and hormone therapy indicated after progression of m-CRPC.

Results:the number of patients in whom the reduction of PSA concentration, process stabilization, tolerability profile were analogous in groups receiving Docetaxel as the first-line therapy and in the group after administration of Octreotide-depo. Analogous data were registered in groups who administered Abiraterone.

Conclusion:the analysis of the therapeutic results didn’t demonstrate any significant differences in groups that received Docetaxel or Abiraterone as the second-line therapy after administration of Octreotide-Depo with groups of patients with received first-line cytotoxic or hormone therapy, which means lack of resistance after application of the prolonged action somatropin analogue to  subsequent schemes of anti-tumour therapy, which allows delaying the dates of the second line chemical or hormonal therapy of CRPC.

Published: November 2017

Modern first-line therapy programs can cure about 80% of patients with classical Hodgkin lymphoma at any stage  of the disease, but 10-30% of patients is refractory and need to continue treatment. The treatment standard for relapsed or refractory forms of classical Hodgkin lymphoma is the second-line chemotherapy with high-dose consolidation under the protection of autologous blood stem cells, but the efficacy of such therapy does not exceed 50% for the entire group of refractory patients. The release of target drugs specific for Berezovsky-Reed-Sternberg tumor cells opens up new prospects for the treatment of classical Hodgkin lymphoma. The article reviews the studies of the use of a new target drug Brentuximab Vedotin for the treatment of relapsed and refractory forms of classical Hodgkin lymphoma.
Truck vibrations caused by rotating shaft deflection

The article deals with the creation of a transient computational model of rotating shaft deflection. This model is used for analysis of vibrations in the truck powertrain with an 8×8 drive. This vehicle is intended for military or fire purposes. However, issues with powertrain vibrations after reaching a certain vehicle speed appear. It was assumed that it was caused by the revolutions of the powertrain shaft and its deflection. Therefore, the aim is to reduce the vibrations affecting the drive comfort and prepare a computational model of the shaft. The transient computational model was created in Matlab software and compared with the results of a second model with the use of the finite element method. The second computational model works as a control version for the first model. The verification was carried out with the use of measurement of shaft deflection and directional vibrations on the powertrain. The conclusion shows the results of the comparison between the old and the new version of powertrain where vibrations were reduced.

Blasting operation exerts adverse effects on the vibration comfort of nearby buildings and structures, and causes a number of civil complaints, discomfort and even lawsuits. Blasting vibration comfort is related not only to the vibration characteristics of blasting and buildings, but also to the non-blasting factors such as, (i) the gender, age, income, psychology, and educational background of the subjects, (ii) the environment they are in, and (iii) the activities in which they are engaged. Based on typical multi-year frequent blasting work cases, three groups of people are selected, and Likert scale method is used to design a detailed comfort survey plan. After tracking, monitoring and surveying over several years, 168 groups of survey data are obtained. The survey results show that, there is a nonlinear relationship between human comfort and blasting vibration amplitude. Moreover, compared with the peak particle vibration velocity (PPV), the absorbed blasting vibration energy (ABVE) index can better reflect the influence of blasting vibration factors. Difference in human comfort between different groups of people and its causes are analyzed. The correlation analysis results show that the correlation coefficients between vibration comfort and four factors (blasting noise, environmental noise, environmental vibration and ongoing activities) range from 0.28 to 0.34. Finally, combining the statistical analysis results, six factors exerting a relatively significant influence on comfort are determined. The outcomes are expected to provide a basis for eventually establishing a multi-level and multi-factor quantitative evaluation model for blasting vibration comfort.

Lamb wave-based structural health monitoring is one of the most widely used damage detection techniques. For quantitatively identifying the damage, damage features that Lamb waves carry may need to be carefully studied by numerical simulation. In this paper, spectral element method (SEM) is used to simulate Lamb wave interaction with open and closed crack. Cracked spectral element models are established for open and closed cracks, respectively. Results calculated by SEM are compared with the conventional finite element method to verify the proposed model. Some simulations are conducted to study different damage features between open and closed crack models. Wave reflection and transmission ratios with different crack depths are also quantitatively analyzed. Damage features obtained are used to conduct a simple experiment to identify the location and size of the crack.
Stiffness matrix modification with vibration test data by displacement feedback technique
Authors: Yuan Yongxin
Published: November 2017

A no spill-over method is developed which uses measured normal modes and natural frequencies to adjust a structural dynamics model in light of displacement feedback technique. By the method, the required displacement feedback gain matrix is determined, and thus the updated stiffness matrix which satisfies the characteristic equation is found in the Frobenius norm sense and the large number of unmeasured high-order modal data of the original model is preserved. The method directly identifies, without iteration, and the solution of this problem is of a compact expression. The numerical example shows that the modal measured data are better incorporated into the updated model.

Human body experiences a long natural evolution to have good movement forms and flexible driving mode, during which process, human muscles have already evolved to a sophisticated bio-actuator, usually used in the bionic design of mechanical structures. The article presents a novel idea for the bionics design of artificial limb or exoskeleton robot, considering the motion level and the driving level of human body simultaneously, i.e. the lower limb segment movement and the muscle activity. Firstly, as the support phase, the most complex process during human walking, we divided it into three sub-phases and studied each other’s variations about the angle and torque by the built motion capture system, which is important for ground reaction force control (GRF control). Secondly, the principal muscles around the knee joint were studied by biomechanical simulation, i.e. the vastus medialis muscle and the biceps femoris muscle, after the data of clinical gait by experiment was imported into the human simulation software. The result showed that the vastus medialis muscle, as Hill three elements model, was the principal muscle during knee’s extension motion, which mainly worked during the support phase and could provide a maximum force of 280 N.m. In contrast, the biceps femoris muscle, as Hill two elements model, was the principal muscle during knee’s flexion motion, which mainly worked during the swing phase and could provide a maximum force of 220 N.m.
Modeling and analysis of stick-slip vibration and bit bounce in drillstrings
Authors: Ren Fushen , Wang Baojin
Published: November 2017

Bit bounce and stick-slip vibration are detrimental to the service life of drillstring and down-hole equipment. A two degrees-of-freedom lumped parameters model is employed to account for bit-rock interaction and coupled vibration. Qualitative analysis to system parameters is performed through analyzing the influence of the angular speed of the rotary table and the length of drillstring on stick-slip vibration and bit bounce. After that, the suppression methods of stick-slip vibration and bit bounce are also given. The nonlinear motions predicted by the model are in agreement with the experimental observations. The study shows that increasing the weight-on-bit(WOB) and the angular speed of the rotary table effectively suppresses bit bounce and stick-slip vibration. What’s more, the posterior models can suppress stick-slip vibration. At the same time, bit bounce can be reduced through applying the models in the middle. When the drillstring is in a higher-length, the stick-slip frequency is at a lower level. However, the intensity of bit bounce is extremely high.

According to the characteristics of Fluid-solid coupling flow field of centrifugal fan, fan aerodynamic performance signal collecting experiment under different conditions are carried out on the centrifugal fan test bed. The relationship among airflow pressure pulsation, noise and vibration are studied by using nonlinear dynamics methods such as phase space reconstruction, correlation dimension, and complexity and so on, which lays the foundation for predicting the fan running status by monitoring the signal of airflow pressure pulsation and the noise. The result shows that the phase diagram of airflow pressure pulsation signal attractor is the most distinct and regular among the three signals. The scope of the phase diagram increases and becomes sparse and confusing with the decrease of the flow, which reflects that pressure pulsation amplitude becomes larger and the internal flow deteriorates gradually with the decrease of flow. The correlation dimensions are calculated with G-P algorithm of the three signals first decrease and then increase with the decrease of the flow. The correlation dimension of the airflow pressure pulsation or noise under stall operating condition can be used as monitoring indicators. The L-Z complexity of the noise increases constantly with the decrease of the flow. But the L-Z complexity of airflow pressure pulsation and vibration first decreases and then increases with the decrease of the flow.
