Inspection of the Integrity of a Multi-Bolt Robotic Arm Using a Scanning Laser Vibrometer and Implementing the Surface Response to Excitation Method (SuRE)

The integrity of a robotic arm was examined remotely via a scanning laser vibrometer (SLV) in order to detect loose bolts. A piezoelectric element (PZT) was bonded on the robot arm for excitation of surface guided waves. A spectrum analyzer generated surface waves within the 20-100 kHz range. The propagation of the waves was monitored with the SLV at the programmed grid points on the robot arm.The surface response to excitation (SuRE) method was used to calculate the spectrums of the signals, and compare the reference scan with the altered scan. Comparisons of before and after the scan showed that after loosening the bolt on the robot arm, spectrums of all the grid points changed to some extent, however, the largest changes occurred in the vicinity of the loosened bolts.The study shows that the SuRE method was capable of detecting the presence and location of loosening bolts using only one PZT element on a complex structure. There are two most important advantages of the SuRE method over the widely used impedance-based technique. The first advantage is the elimination of an expensive impedance analyzer; the second advantage is remotely monitoring capability as long as the surface is excited properly.

From Misconceptions to Constructed Understanding The Fourth International Seminar on Misconceptions Research ( 1997 )

This paper describes a research project based on the implementation of a computer-based mathematics curriculum, characterised by tasks designed to promote exploration and investigation of geometric concepts. The project investigated the domain of early mathematical learning and application, with an emphasis on the development of spatial sense and geometric knowledge. It also it examined a learning context that encouraged children's active construction of mathematical meaning, rather than the passive transmission of facts. Additionally, it considered the implications of utilising computers as a dynamic learning environment. It was found that the computer-based investigation proved to be a nourishing environment for application of existing mathematical understandings and the construction of new ideas. The children participating in this study demonstrated many mathematical “moments” and post tests revealed considerable improvement in geometric understanding. This success however, was seen to rely on the supportive role played by the researcher. The project report proposed that the results of this type of computer-based project would be highly dependent on teacher-support mechanisms such as scaffolding. Further research is warranted to examine the nature of teacher support and intervention during on-computer exploration tasks. It is suggested that this scaffolding should be characterised in to categories such as technical, social, emotional and cognitive. Additionally, it is deemed important that teachers are aware of these scaffolding processes and can determine when it is appropriate to intervene in the exploration process and when scaffolding should be withheld. It is anticipated that understandings of this nature will lead to richer learning experiences for young children exploring with technology-based tasks.
A Primer on Geospatial Impact Evaluation Methods , Tools , and Applications

The growing availability of georeferenced data on development investments and outcomes has opened up new opportunities to understand what works, what doesn’t, and why at a substantially lower time and financial cost. Whenprecisely georeferenced interventiondata are fusedwith in-situ and remotely sensed data on outcomes like poverty, child mortality, deforestation, and governance, quasi-experimental methods of causal inference can be used to control for potential confounds and omitted variables at fine geographic levels. We introduce these geospatial impact evaluation methods, review their advantages and disadvantages, and describe their relevance and use across countries, sectors, intervention types, and development organizations.

LIMITATIONS TO THE ORGANIZATIONAL LEARNING CAPACITY ON COMPLEX ENVIRONMENTS : THE CASE OF THE AERIAL SAFETY

The purpose of this paper is providing proposals to recover the learning capacity in complex environments where this capacity seems to decrease. To do this, the aerial safety learning model and its collateral effects will be analyzed. During years the aerial safety has shown high pace improvement. Its learning process has based on heavy use of technological and normative development. However, it seems to have reached a plateau even though the technological and normative drivers continued to be present. Therefore, the analysis of aerial safety could help understanding the learning process and its barriers in aerial safety as well as in other environments.
Diaphragmatic Evaluation

The diaphragm is a dome-shaped membrane that delimits the thoracic from the abdominal cavity. In adults it covers an area of about 900 cm2. It represents the principal inspiratory muscle and it can shorten itself to 40% from Residual Volume (RV) to Vital Capacity (VC). The diaphragm has extensive functional reserve; in fact, a unilateral paralysis of the phrenic nerve generates only a mild respiratory dysfunction [4].

PROSPECTS FOR MAPPING FROM HIGH-RESOLUTION SATELLITE IMAGERY

The new technology of high-resolution satellite imagery has demonstrated its metric potential for mapping. Both the Ikonos and Quickbird imaging systems offer ortho-image products meeting map accuracy specifications to scales as large as 1:10,000. The cost of acquiring such mapping products is, however, quite considerable and beyond the means of many prospective international users, especially in the developing world. Fortunately, there are methods available for users with photogrammetric capability to generate high-accuracy mapping from lowest-cost, Ikonos Geo and Quickbird Basic imagery, with the possibility of achieving savings of 60-70% over the cost of Ikonos Pro and Quickbird Orthorectified Imagery products. This paper summarises experiences gained with two such practical alternative approaches to metrically processing high-resolution satellite imagery, namely bias-correction for rational functions and affine projection models. These offer the prospects of much more affordable mapping from high-resolution satellite imagery.
Long noncoding RNA MT 1 JP suppresses gastric cancer cell proliferation and migration in TGF-β induced EMT

Background: The early diagnosis rate of gastric cancer (GC) is low. Further research on the mechanisms of gastric cancer occurrence and development and finding biomarkers for the invasion and metastasis of gastric cancer are of great significance for the prevention and treatment of gastric cancer. Objective: To screen the differential expressions of long chain noncoding RNA (LncRNA) related to gastric cancer and to explore new targets for the diagnosis and treatment of gastric cancer. Methods: The microarray data associated with gastric cancer were downloaded in Gene Expression Omnibus (GEO), the expression difference of long noncoding RNA was analyzed with R software, and gene annotation and clustering was performed in the DAVID database. The differences in gene expression were enriched in the signaling pathways and in the protein interaction network. GES-1, BGC-823 cells were cultured with 5 ng/ml TGF-β, with the aim of stimulating the cells and evaluating the changes in cell migration, proliferation, and invasiveness after establishing an epithelial-mesenchymal transition (EMT) cell model. E-cadherin, N-cadherin, and vimentin expression levels were detected by Western-blot, and LncRNA MT1JP was investigated by performing a qRT-PCR. The relationship between the epithelial-mesenchymal markers and the expression level of LncRNA MT1JP was analyzed using Spearman’s test. Results: The microarray GSE103236 involving 10 normal tissues and 9 gastric cancer tissues was analyzed. Based on the data from the microchip, 65 differentially expressed genes including 40 up-regulated LncRNAs and 25 down-regulated LncRNAs were screened. The results of the gene enrichment analysis showed that most of the differentially expressed genes were enriched in the cell matrix and adhesion molecules (P<0.01). The cell proliferation, migration, and invasion abilities of GES-1, BGC-823 induced by TGF-β were significantly enhanced (P<0.01). In the TGF-β induced group, the expression levels of LncRNA MT1JP and E-cadherin were significantly decreased in the BGC-823 cell line. However, the expression levels of N-cadherin and vimentin were increased in the TGF-β induced EMT group (P<0.01). Conclusions: The expression of gastric cancer related LncRNA is different. Most LncRNAs may be associated with the process of gastric cancer invasion and metastasis. The low expression level of LncRNA MT1JP can promote the EMT process of gastric cancer cells. It may be a major target for the invasion and metastasis of gastric cancer. Additional exploration of its related mechanisms is expected, which could become a new target for the diagnosis and treatment of gastric cancer.
Catechins green tea upregulates the expression of ABCA1, ABCG1, and SRB1 in rats induced atherogenic diet

The efflux of cholesterol from macrophage to liver is known as reverse cholesterol transport (RCT). Impaired cholesterol efflux leads to cholesterol accumulation in macrophages. Therefore, how to increasing cholesterol efflux may be an effective strategy for atherosclerosis prevention. Key molecules that play a vital role in the efflux of cholesterol from macrophage are Adenosin Tri Phosphate (ATP)-binding casette transporters A1 and G. This study was undertaken to clarify the effect of Catechins on the expression of specific transporters such as ATP-binding cassette sub-family A member 1 (ABCA1), ATP-binding cassette sub-family G member 1 (ABCG1) from macrophage to liver, and scavenger receptor class B type I (SRB1). This research was done on Wistar rats induced atherogenic diets. SRB1 is one of the transporters to facilitate the delivery of cholesterol from the macrophage to the liver. The SRB1 pathway mediated the selective uptake of cholesteryl ester. Catechins significantly increased the mRNA expression of ABCA1 and ABCG1 in aorta as well as SRB1 of liver also increased. Thus, Catechins decreased the total cholesterol levels in aorta and serum. Catechins can be developed as a potential agent to increase ABCA1 to inhibit atherogenesis process. In conclusion, this study indicates that the potential anti-atherogenic properties of Catechins could be explained, at least in part, as being due to upregulated expression of ABCA1, ABCG1, and SRB1 through activation liver X receptor signaling pathway.
Effective Optimal Power Flow Solution with Transient Stability Constraints based on Functional Transformation Technique

Optimal power flow with transient stability constraints (OTS) can coordinate the economical efficiency, reliability and quality of the electric power at the same time. However, OTS is a nonlinear infinite optimization problem, which is difficult to be solved precisely even for power systems of small dimension. In this paper, we propose a new transformation method, which exactly converts the infinite-dimension OTS into a finite-dimension optimization problem. The transformed OTS problem has the same variables of the associated OPF problem, and is tractable even for the large-scale power systems with a large number of transient stability constraints. In addition, this paper uses a modified SQP (sequential quadratic programming) approach to solve the formulated nonlinear optimization problem. By using this approach, the optimal operation points can be determined in short calculation time. Key-Words: Transient stability, Optimal power flow, Sequential quadratic programming, Power system, Functional equality, Available transfer capability.

Diverse everyday information practices in Australian households

Qualitative research into the everyday information-seeking practices of eight diverse households in the city of Melbourne, Australia permitted insights into the variability in dynamics around information practices. The current study combines an information practice approach to information-seeking with finer detail on use of the Internet. Rather than treat the Internet as a monolithic entity, this study looks separately at the use of more recent Internet technologies such as social media and Wikipedia. The study examines the type of information that people seek, the ways in which they stay informed and their engagement with a range of information resources. In particular, the study illustrates the enormous disparity in the level of information resources available to participants. It also illustrates the extent to which use of the search engine, Google, has become naturalised within the everyday information practices of some Internet users in Australia. This study indicates that public libraries still have particular importance for more disadvantaged members of the population.
1 Relativistic Electron Heating in Focused Multimode Laser Fields with Stochastic Phase Purturbations

A direct relativistic electrons acceleration simulation model with a given electromagnetic field which is determined by wave packet parameters is considered. The multimode time-spatial structure of focused Nd-laser beam with stochastic phase disturbances of each spectral component is taken into account as a source of random forces. The electron energies more than 10 MeV are derived even at moderate flux densities of 10 W/cm. The developed numerical code gives it possible to obtain quantitative energy distribution function in relation to both field intensities and temporal U-shape of laser pulse. The efficient heating of electrons can be triggered in the presence of counter propagating wave being reflected from critical plasma area with varied reflection coefficient. The heating mechanism occurs with a delay relative to the beginning of the pulse when the laser fields exceed some threshold amplitudes. The qualitative comparison of simulation results with the experimental data is given as evidence that this mechanism is not unreasonable.

Novel real-time polymerase chain reaction assay for quantitative detection of Chlamydia trachomatis in vaginal and cervical secretions

Chlamydia trachomatis (C. trachomatis) is an important sexually transmitted disease pathogen associated with infertility and several urogenital infectious diseases. A variety of detection methods have been developed for C. trachomatis, including the isolated cell culture method, PCR, and real-time polymerase chain reaction (RT-PCR). These methods have inherent limitations, however. The current study developed a novel RT-PCR assay specific for quantitative detection of C. trachomatis elementary bodies (EBs) in vaginal and cervical secretions without DNA extraction. Based on homology analysis between Chlamydia and other common genital tract infectious pathogens, oligonucleotide primers were designed to target the C. trachomatis ompA70-213 (ompA1) gene. These primers were confirmed in HeLa 229 cells infected with C. trachomatis and in a mouse model of genital C. trachomatis infection. Moreover, RT-PCR was used to detect C. trachomatis in vaginal and cervical secretions from 86 female patients. These results were compared with those of the traditional C. trachomatis isolated cell culture method, evaluating the sensitivity and specificity of this novel RTPCR assay. The ompA1 gene was found to have high homology across several Chlamydia serotypes. The newly developed RT-PCR assay provided highly sensitive detection of EBs in genital tracts of the mouse model and in vaginal and cervical secretions of the 86 female patients, compared with the traditional detected method.
The office approach for diagnostic hysteroscopy

Although operative hysteroscopy has progressively been accepted for the treatment of intrauterine pathologies, diagnostic hysteroscopy is still not widely and routinely used. Whereas almost all urologists utilize office cystoscopy to evaluate bladder pathology, it is estimated that less than 20% of gynecologists utilize office hysteroscopy to evaluate uterine pathology. Conventional hysteroscopy, defined as a procedure performed with an instrument of 5.0 mm total diameter and with CO2 as a distention medium and in which the insertion of the hysteroscope is facilitated by the use of a speculum and a tenaculum, has not been proven to be a technique accessible for all gynecologists and applicable in a routine set-up. Recently, well-conducted scientific studies have highlighted some important elements that can explain this underutilization of hysteroscopy as a first-line diagnostic procedure both in the office and in the conventional inpatient clinic. Nagele et al have proved that CO2 induces significantly more pain than a watery solution when used as distention medium. Furthermore, a watery distention medium has the advantage of cleaning the environment, leading to a better and easier visualization of the uterine cavity than with the conventional CO2. In a prospective randomized trial (PRT) we have recently proved the importance of the instrument diameter for both patient compliance and visualization quality. In the same study we also demonstrated that both the experience of the surgeon and the anatomical difficulties determined by patient’s parity play a key role when a conventional hysteroscope is used. With the use of a mini-hysteroscope, however, neither surgeon’s experience nor patient’s parity influence the results, offering a significant improvement for patient compliance and visualization quality. Office hysteroscopy is wrongly associated to a large extent with the disadvantages of conventional hysteroscopy and unfortunately many physicians, including gynecologists who do not witness the recent technical developments, believe that office hysteroscopy is similar to conventional hysteroscopy but performed in an office setting. In addition, the benefits of incorporating hysteroscopy as a first-line diagnostic tool for the investigation of abnormal uterine bleeding (AUB) and infertility are still not completely assumed by the medical community, whereas the lack of expertise to perform the procedure is evident.
Photojournalism and the Notion of Objectivity – The Particularity of Photography and its Relationship with Truthfulness

News journalism is a practice of reconstructing the reality. It needs credible images to support its evidence. This notion is closely tied to the eyewitness role within journalism. Åker (2012) says that the press photo is important to journalism because of its “level of authenticity”. So the resemblance between that towards which the camera is pointed and that which we see in the photograph needs to be absolutely convincing (ibid. 327). Furthermore, if the truthful nature of news photographs collapses, the whole credibility of the news collapses as well (Mäenpää and Seppänen, 2010: 454).
