Background: Chronic fatigue syndrome (CFS) is characterized by severe fatigue persisting for at least 6 months and leading to considerable impairment in daily functioning. Neuroimaging studies of CFS patients have revealed alterations in prefrontal brain morphology. However, it remains to be determined whether these alterations are specific for fatigue or whether they relate to other common CFS symptoms, e.g. chronic pain, lower psychomotor speed, and reduced physical activity. Methods: We used magnetic resonance imaging to quantify grey matter volume (GMV) and Nacetylaspartate/creatine ratio (NAA/Cr) in a group of 89 female CFS patients. Building on previous reports, we tested whether GMV and NAA/Cr in the dorsolateral prefrontal cortex (DLPFC) are associated with fatigue severity, pain, psychomotor speed, and physical activity, while controlling for depressive symptoms. We also considered GMV and NAA/Cr differences between CFS patients and 26 gender-, age-, and education-matched healthy controls (HC). Results: Presence of pain symptoms was the main predictor of both GMV and NAA/Cr in the left DLPFC of CFS patients. More pain was associated with reduced grey matter volumes and NAA/Cr, over and above effects of fatigue, depressive symptoms, physical activity and psychomotor speed. In contrast to previous reports and despite a large representative sample, global GMV did not differ between the CFS and HC groups. Conclusions: CFS, as diagnosed by CDC-criteria, is not a clinical entity reliably associated with reduced GMV. Individual variation in the presence of pain, rather than fatigue, is associated with neuronal alterations in the DLPFC of CFS patients.


This is a commentary on the short communication by Raj et al [1] in this issue of the British Journal of Radiology (BJR).

The first rule of all radiology departments is that a pacemaker is a contraindication to MR scanning. Quite rightly, we go to great lengths in routine clinical practice to ensure that patients with an in situ pacemaker do not enter the scanning suite. This involves the clinical referrer signing part of the request card indicating there is no known contraindication to MR and rigorous questioning of the patient by the MR department radiographers and support staff before they are allowed into the controlled scanning area. There are several theoretical risks if a patient with a pacemaker undergoes an MRI examination [2]. Firstly the electronic circuits of the pacing box may malfunction and effectively be erased, particularly by the static magnetic field, which leads to a lack of pacing that could be life-threatening in a patient who is pacemaker dependent. Secondly, the rapidly changing magnetic field gradients may induce currents in the pacing system, which can lead to hyperstimulation and rapid over-pacing causing a negligible cardiac output. The radiofrequency (RF) pulse may also do this to some degree. Thirdly, the pacing box or lead may move as a result of the strength of the static magnetic field if there are ferromagnetic components within the pacing system. Finally, there is a risk that the pacing electrode, acting as an antenna, will absorb the RF pulses and localise this energy in the electrode tip as heat, which might burn and potentially rupture the myocardium, particularly given the thin walls of the right-sided cardiac chambers.

Across the world, several hundred patients have inadvertently undergone an MR examination despite having a pacemaker in place [3]. In the majority of cases there were no untoward events, which suggests that the actual risk is low. However, deaths have occurred and although there is little conclusive evidence, the identification of ventricular fibrillation in some of these patients suggests dysrhythmia owing to rapid chaotic pacing as a likely cause of death. It seems that none of these deaths occurred when there was a physician present directly supervising or monitoring the scan [2]. In several published small studies of patients knowingly undergoing MR examinations with pacemakers in situ there were no reported deaths, although these studies have clearly been performed in highly specialised institutions [4].

In practical terms, once an individual patient has a permanent pacemaker inserted they will never be able to undergo an MR scan for the rest of their lives. Although pacing boxes can be changed, the pacing leads are essentially permanent. This is problematic for these patients, given the recent data that states there is a 50–75% chance of a patient with a pacemaker or implanted cardiac defibrillator needing an MR scan at some point in their life [5]. As a result, pacing technology manufacturers have focused their research for some time on developing an MR compatible pacing system. Although such systems are in various stages of development, one device, the SureScan (Medtronic, Minneapolis, MN) pacing system, has been shown to be safe under specific conditions in a large cohort of patients and is available for use in clinical practice [6,7]. There are several principles to its safety. Firstly, the lead has been designed to be a poor conductor of RF energy; secondly, the internal circuitry of the pacing system has been improved to lessen the chance of cardiac stimulation and disruption of the internal power supply; and thirdly, the pacing box can be specifically set to an MR-safe mode for the purposes of the scan and then reset afterwards. These pacing systems have a safety rating of "MR conditional" because there are constraints on the conditions of their use i.e. they are safe only under certain well-defined conditions.

The SureScan device has largely been tested, in published literature, on patients undergoing MR of the brain or lumbar spine. MR examinations of the heart and thorax have been seen as the ultimate test of this device given that the pacing system is entirely within the imaging field. A number of patients with this pacing system have successfully undergone cardiac MRI (CMRI). In this month's BJR, Raj et al [1] present elegant MRIs of one of these pacing leads situated in the RV during a CMR study. They also detail the strict safety requirements for a patient undergoing this examination, equivalent to the conditions that make this device MR conditional. The indications for CMR, in a patient with one of these pacing devices present, remains to be determined and it is not yet clear whether the image quality will be good enough to, for example, assess reliably for an RV dysplasia.

This is a new era indeed, but this is only the start. In the early stages of clinical use it seems appropriate that all MR scans in patients with this device in situ are performed in regional cardiac units, with support from the local MR physics department and the manufacturers. It is clearly essential for an electrophysiology technician to be present to programme and reprogramme the device before and after the scan and it would seem appropriate in these early stages for a cardiologist to also be present for the scan. Raj et al [1] are right to emphasise the multidisciplinary approach required in the use of these pacing systems as the radiologist cannot and must never be left to manage these cases alone. There needs to be a rigorous process of checks prior to MR scanning to ensure the patient's safety. One can foresee difficulties with patients apparently having a safe device but with very little confirmatory documentation being present. Although the manufacturers have designed the pacing box and the electrodes to have characteristic markings that can be identified on a radiograph, it cannot be overstated that there is no point in having an MRI compatible pacing box if the leads are MRI unsafe. Finally, cardiologists need to be reminded and encouraged to insert these devices, particularly if there is a high likelihood of the patient needing an MR scan in the future that can be predicted at the time of pacemaker insertion. This surely is an opportunity to create reliable local documentation, which is easily identifiable in the patient's notes, that the device is MR compatible so that future MR scans can be planned in confidence. The manufacturer currently provides a system of recommended checks, documentation and advice, but this process will become more complex as more of these devices come onto the market from different manufacturers. It is likely, therefore, that local and national guidelines will be required because the stakes are high if the strict safety measures that these devices require are not followed to the letter. The message must remain — if in doubt, don't scan.


We have evaluated a new concept for a variable light valve and thermal insulation system based on nonimaging optics. The system incorporates compound parabolic concentrators and can readily be switched between an open highly light transmissive state and a closed highly thermally insulating state. This variable light valve makes the transition between high thermal insulation and efficient light transmittance practical and may be useful in plant growth environments to provide both adequate sunlight illumination and thermal insulation as needed. We have measured light transmittance values exceeding 80% for the light valve design and achieved thermal insulation values substantially exceeding those of traditional energy efficient windows. The light valve system presented in this paper represents a potential solution for greenhouse food production in locations where greenhouses are not feasible economically due to high heating cost.


An electronic device is described which will maintain stress constant to within +or-0.1% during creep tests. The device is used in conjunction with conventional dead-load creep apparatus and, in common with all constant-stress methods, requires that the deformation of the test specimen occurs uniformly and at constant volume. The device is not strain-limited and will maintain stress constant even to the large strains characteristic of deformation in superplastic materials. Its performance compares favourably with the best cam lever machines currently available, with the advantages that the absolute value of the stress on a specimen may be calculated throughout the course of a creep test. Unlike cam lever machines, it can be used to test specimens of widely different gauge lengths with equal facility. Creep tests on 20%Cr/25%Ni/Nb-stabilised austenitic steel are described to illustrate the use of the device.

Technology use is ubiquitous in nursing, therefore it is vitally important that pre-licensure nurses have opportunities to develop nursing informatics skills and abilities that prepare them to practice in an ever-changing environment filled with technology. This quantitative, qualitative, interpretive, descriptive pilot study takes an established teaching method (simulation) and evaluates how baccalaureate nursing students can use an emerging disruptive technology (EDT) to impact decisions at the point of care. Eleven (100%) of the participants successfully completed two tasks using Google Glass, (GG): (a) they accessed data at the point of care; (b) completed a Situation Background Assessment Response (SBAR) report to a remote provider hands free. Two themes about using GG focused on communication and safety. This pilot indicates that using EDT in pre-licensure nursing education may be an effective way to narrow the education practice gap in nursing informatics, especially as it applies to nurse as knowledge worker.


This research project aimed to develop a condition monitoring system for the final production quality of pharmaceutical tablets and detection capping and lamination during powder compression process using the acoustic emission (AE) method. Pharmaceutical tablet manufacturers obliged by regulatory bodies to test the tablet's physical properties such as hardness, dissolution and disintegration before the tablets are released to the market. Most of the existing methods and techniques for testing and monitoring these tablet's properties are performed at the tablet post-compression stage. Furthermore, these tests are destructive in nature. Early experimental investigations revealed that the AE energy that is generated during powder compression is directly proportional to the peak force that is required to crush the tablet, i. e. crushing strength. Further laboratory and industrial experimental investigation have been conducted to study the relationship between the AE signals and the compression conditions. Traditional AE signal features such as energy, count, peak amplitude, average signal level, event duration and rise time were recorded. AE data analysis with the aid of advanced classification algorithm, fuzzy C-mean clustering showed that the AE energy is a very useful parameter in tablet condition monitoring. It was found that the AE energy that is generated during powder compression is sensitive to the process and is directly proportional to the compression speed, particle size, homogeneity of mixture and the amount of material present. Also this AE signal is dependent upon the type of material used as the tablet filler. Acoustic emission has been shown to be a useful technique for characterising some of the complex physical changes which occur during tabletting. Capping and lamination are serious problems that are encountered during tabletting. A capped or laminated tablet is one which no longer retains its mechanical integrity and exhibit low strength characteristics. Capping and lamination can be caused by a number of factors such as excessive pressure, insufficient binder in the granules and poor material flowabilities. However, capping and lamination can also occur randomly and they are also dependent upon the material used in tabletting. It was possible to identify a capped or


Using the combination of Citespace and CNKI database literature analysis, this paper analyzes the core journals of entrepreneurship research and CSSCI source journals in the CNKI database, and finds that domestic entrepreneurship research is significantly affected by national policies; The scope and theme range are constantly expanding, and the perspectives are gradually diversified, but they have not formed scales; the research shows a distinct transitional and phased nature, which has not become a prominent research center; the authoritative research results of domestic academic circles are few and so on. The main reason is that current research is based on mainstream economic theory, and this is limiting the way entrepreneurship research is full of changes and uncertainties. Therefore, in the future, entrepreneurship will still maintain a high degree of attention, but without the breakthrough of entrepreneurial theory, it is difficult to form widely accepted research conclusions in the short term.This is also the bottleneck of entrepreneurial research.


Osteoarthritis (OA) is a complex disease caused mainly by inflammatory mediators. The last non-operative treatment modality, when other conservative treatments are ineffective is intra-articular (IA) injections with corticosteroids, viscosupplements or blood-derived products. Purpose: The aim of this study was to compare the efficacy of Cellular Matrix-PRP-HA (CM-PRP-HA), a combination of autologous platelet-rich plasma (PRP) and hyaluronic acid (HA) prepared using a dedicated medical device, to HA alone in IA injections for treatment of osteoarthritic knee. Methods: The study involved 100 symptomatic patients with knee cartilage degenerative lesions (Kellgren Lawrence scale grade 0 to III). Fifty patients were treated with IA injections of autologous CMPRP-HA combination that was repeated 3 times with 3 weeks interval, while the other 50 patients were treated with IA HA injections. All patients were clinically evaluated pretreatment (basal) and at 2,6 and 12-month follow up visits by using Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Results: At each follow up visit, both groups showed a highly significant improvement when compared with the basal assessment and the same results were obtained upon comparing 12month follow up visit with the 2month one. The infra-group comparison showed, at each follow up evaluation, a significantly higher improvement for the group treated with CM-PRP-HA in respect to HA alone. Conclusion: IA injections of CM-PRP-HA showed more efficacy than HA injections in reducing pain and symptoms of mild to moderate knee degenerative osteoarthritis.


The six papers in this special mini-issue are expanded versions of papers presented at the 24th International Symposium on Space Terahertz Technology, held in Groningen, The Netherlands during April 8-10, 2013.


We describe an inversion method for 3D geomagnetic data based on approximation of the source distribution by means of positive constrained Gaussian functions. In this way, smoothness and positivity are automatically imposed on the source without any subjective input from the user apart from selecting the number of functions to use. The algorithm has been tested with synthetic data in order to resolve sources at very different depths, using data from one measurement plane only.The forward modeling is based on prismatic cell parameterization, but the algebraic nonuniqueness is reduced because a relationship among the cells, expressed by the Gaussian envelope, is assumed to describe the spatial variation of the source distribution.We assume that there is no remanent magnetization and that the magnetic data are produced by induced magnetization only, neglecting any demagnetization effects. The algorithm proceeds by minimization of a χ2 misfit function between real and predicted data using a nonlinear Levenber...


Eight patients with Addisonian pernicious anaemia were given 20 mg of prednisolone daily for up to 20 weeks. Improvement in absorption of vitamin B12 as judged by the Schilling test occurred in six cases and was pronounced in four, and there was increased secretion of gastric intrinsic factor in four cases. Gastric biopsies showed regeneration of specialized gastric glands in four cases; chief cells were demonstrated histochemically and parietal cells by an immunofluorescent procedure using serum containing parietal cell antibody. There was no correlative change in titre of serum antibody to gastric parietal cells or gastric intrinsic factor. The improved absorption of vitamin B12 was not maintained after prednisolone was stopped, indicating that the regenerated gastric mucosa reverted to the atrophic state. These effects of corticosteroids on gastric function in pernicious anaemia are in keeping with their known capacity to modify damage resulting from antigen–antibody interaction.


SPRING 2001 chapter on cholera covers familiar ground from the miasmatic theory of disease through Chadwick and John Snow to the gradual acceptance of germ theory. Halliday credits the eradication of cholera to Bazalgette's main drainage system and to the MBW's insistence that local water companies find clean sources. He also celebrates Bazalgette's five-mile embankments along the Thames waterfront, which turned a filthy stretch of coal wharves and mud-strewn ferry landings into a vast esplanade with boulevards and gardens, all enclosing the low-level sewer line, utility pipes, and a section of the new underground railway. The chief engineer supported experiments that made Portland concrete a reliable material for large-scale hydraulic construction. His success at the MBW led to additional street-building projects, the renovation of housing, and the provision of open spaces such as Leicester Square. Using Bazalgette's career as a framework, Halliday brings together developments that have been treated separately in previous works. His biographical approach eschews theorizing and interpretation in favor of striking events and personalities. A chapter on streets, housing, and open spaces, for example, which echoes a similar chapter in Owen's The Government of Victorian London (1982), highlights financier Albert Grant's campaign to develop Leicester Square for public use with his own funds. Grant's picturesque life is then rehearsed in one of the many shaded boxes scattered throughout the book. Most of these potted biographies are useful but quite a few seem included for curiosity's sake rather than for relevance to the narrative. Another graphic feature, for which the author may not be responsible, is the display of short excerpts from the text along the margins, in the style of popular news magazines. These text-bites prove distracting, as they often misrepresent the accompanying paragraph. The book's best feature is an exceptionally rich array of illustrations. The author used the usual picture archives but also exploited a large cache of cartoons, paintings, newspaper portraits, photographs, and maps from the Thames Water Board. These are appropriately placed to depict what Victorian prose can only suggest. A center section of color photographs includes a striking interior view of the low-level intercepting sewer, still functioning today as Bazalgette designed and built it over a century ago. Dale H.

The advent of digital audio workstations and other digital audio tools has brought a critical shift in the audio industry by empowering amateur and professional audio content creators with the necessary means to produce high quality audio content. Yet, we know little about the accessibility of widely used audio production tools for people with vision impairments. Through interviews with 18 audio professionals and hobbyists with vision impairments, we find that accessible audio production involves: piecing together accessible and efficient workflows through a combination of mainstream and custom tools; achieving professional competency through a steep learning curve in which domain knowledge and accessibility are inseparable; and facilitating learning and creating access by engaging in online communities of visually impaired audio enthusiasts. We discuss the deep entanglement between accessibility and professional competency and conclude with design considerations to inform future development of accessible audio production tools.


Background
Changes of perceptual body size distortion and body dissatisfaction during inpatient psychosomatic treatment were assessed. Differences between patients with anorexia and bulimia nervosa were compared.

Methods
Forty-one female patients with anorexia and 37 with bulimia nervosa were examined at beginning and end of an inpatient psychosomatic treatment. Body images were assessed by the somatomorph matrix and by the Eating Disorder Inventory (EDI-2).

Results
Both groups showed a distorted body size perception at the beginning of treatment. This decreased with the bulimia patients, with anorexia patients it largely remained in spite of a successful increase in weight. With bulimia patients body satisfaction improved, whereas it hardly changed with anorexia patients.

Conclusion
Bulimia patients were able to positively modify their body images. Treatment might have enabled patients with anorexia to maintain their level of body satisfaction and to tolerate a bigger perceived body image while they significantly gained weight.

Software engineering education is on a different level of maturity in different countries. In many countries software engineering is still on the way to be established. The aim of this workshop is to attract faculties to discuss and provide successful examples and lessons learned about development of software engineering courses or a curriculum on bachelor and master level, as well as the ability to increase international collaboration. The second goal of the workshop is to attract local communities to participate in the workshop and in the conference.


DNA polymorphism of the human major histocompatibility complex (MHC)‐linked complement C4 genes was studied using restriction enzymes XbaI and TaqI, and Southern hybridization. The results show that some, but not all, C4 phenotypes can be divided into subtypes. Analysis of MHC haplotypes indicates that in each extended MHC haplotype, i.e. in the haplotypes having a particular combination of HLA and complotype phenotypes in significant linkage disequilibrium, the C4 genes always produce just one 'conserved' restriction enzyme fragment pattern, while in the other haplotypes the C4 genes are more heterogeneous. Furthermore, the findings provide preliminary evidence for a C4B gene duplication, and suggest that the C4 genes may often be 'corrected' alike.

Through watching the video-records of the Liaoning Teenagers'Sanshou Competition 2005,we analyzed the statistics of the leg technique using in the matches,and got the result that the whip leg was the most utility times of leg techniques;the side-heel-kick was the highest hitting percentage of leg techniques;and the heel-kick was the weakest among their three.


Movements in geological areas are mostly concentrated on faults or slipping zones. Detection of movements reaching critical values is of crucial importance to avoid losses and harms. The paper presents a new technology of detecting deformations and movements in soil or rock massifs. The core part of the sensing system is a tiny rod with embedded optical sensor fibres. This deformation measurement system was developed and the sensing rod can be installed in a borehole and enables the detection of beginning soil movements. The amount of deformation in soil or rock formations can then be estimated. The sensing rod has an outer diameter of 3 mm to 6 mm and contains several optical fibres. One fibre is used as online measurement system and provides integral strain information along the whole length of the rod. In case of a safety-relevant deformation (warning signal), the second sensing system based on fibre Bragg grating sensors positioned close to the expected shear zone will be activated and records then resulting deformations in detail.


The Current Concern over juvenile delinquency has brought this problem more forcefully to the attention of physicians. It becomes important, therefore, in a period when people are charging off in all directions in search of a panacea for the prevention of juvenile delinquency, for us to remain aware of the fact that juvenile delinquency is a symptom and not a diagnosis. Just as headache and abdominal pain are symptoms which challenge the diagnostic skill of the physician, so juvenile delinquency is a symptom which is similarly challenging. The symptom per se never tells us the cause; the cause becomes a matter for further investigation.
 Those who seek a single formula for the prevention of all delinquency are destined to experience nothing but frustration. We should recall that some very good minds have struggled with this problem over many years. In this field, as in all others, those who are ignorant of history are destined to repeat it.
 A brief historical note is in order to indicate that the role of physicians in programs concerned with the prevention and treatment of the delinquent is not a new one. A Chicago physician, Dr. William Healy, in 1909 organized the first child guidance clinic in the world in an effort to deal with children brought to the attention of the court because of their antisocial behavior. The establishment of this clinic under medical auspices served as a stimulus for the development of child psychiatry as a discipline. Dr. Healy left behind him in Chicago the Institute for Juvenile Research which has carried on work in the field of delinquency for 50 years; he then went on to found the Judge Baker Clinic in Boston.


Disclosed are an eyeglass-less 3D display device, and a device and method that compensate for a displayed margin of error. The display device acquires an image of an IID image captured by a single camera, and compensates for a margin of error due to a discrepancy between the designed position of a micro lens array located on one surface of a 2D panel and the actual position thereof, so as to provide a high-quality 3D image.


The authors developed a new method for applying well known tools RCM, RBI and SIFpro. Risk-based Inspection (RBI) is an optimal maintenance process used to examine and maintain equipment. It is a widely applied strategy in processing industries (oil and gas industry, petrochemical plants) (Filimonov, Belatskiy, 1973). RBI is used to specify monitoring plans for pressure equipment, including pressure vessels and piping (Henly, Kumatoto, 1984). Safety Instrument Function process (SIFpro) is a strategy used to optimize control loop inspection intervals (Belyaev, 1969). SIFpro examines random safe and unsafe safety system failures, including emergency signals. It is used for measuring devices. SIFpro is usually preceded by HAZOP or PHA. These methods determine the areas where SIF is required. The method aims at reducing risks owing to adequate maintenance. The methodology is based on the complex use of all three methods simultaneously, not separately. The developed approach involves only one control group for reliability and risk treatment centered maintenance (RRTCM) with simultaneous use of RCM, RBI and SIFpro methods. The approach reduces the duration of engineering works. The activities were divided into five stages and structured so that to eliminate double application of the tools. The new approach helps to save 45-50% of the workload and significant financial resources. But RRTCM implementation can face some obstacles due to changes in the organizational structure, responsibilities and other business processes. RRTCM implementation difficulties can result from high demand for data input, analysis quality, maintenance, management, poor company culture, low top management support, etc. © 2018 Published by Future Academy www.FutureAcademy.org.UK


We report 10 cases of Campylobacter fetus infection, isolated during a 7-month period, which were all sensitive to erythromycin. The aetiology and epidemiology are discussed.


SUMMARY Seismic reflection profiles from Mesozoic oceanic crust around the Blake Spur Fracture Zone (BSFZ) in the western North Atlantic have been widely used in constraining tectonic models of slow-spreading mid-ocean ridges. These profiles have anomalously low basement relief compared to crust formed more recently at the Mid-Atlantic Ridge at the same spreading rate. Profiles from other regions of Mesozoic oceanic crust also have greater relief. The anomalous basement relief and slightly increased crustal thickness in the BSFZ survey area may be due to the presence of a mantle thermal anomaly close to the ridge axis at the time of crustal formation. If so, the intracrustal structures observed may be representative of an atypical tectonic regime.


EPS (Electric power system) of the satellite is a critical aspect for the success of the satellite mission, likewise the optimum usage of the available power resources for the satellite EPS is the main key of success for the system design process. Furthermore, implementing the modular concept in the design of the satellite EPS improves the reliability and quality of the design and makes the platform adaptable for various missions and payloads. Optimizing the usage of solar array output power during beginning of life and exiting from shadow periods while there are excess of power from the solar arrays stabilizes the bus voltage within the required designed margins and consequently protects all satellite loads connected to the main bus. A hybrid modular configuration is proposed including linear and non-linear regulation for implementing the sequential switching shunt regulation of the solar array output power, the proposed configuration employs the fuzzy logic concept to issue the switching pattern for the solar array sections subjected to the error signal in the feedback loop of the bus voltage. Moreover, a simulation is performed for the three domain control concept of the EPS demonstrating how the bus voltage levels decide the operating domain of the EPS.


This research was conducted to produce rice starch microcapsules from regular rice starches (22-24% solid w/w) with the small amount of each suitable binding agent (0.10-0.30%): acacia, carboxymetylcellulose and gelatin by using spray dryer. Scanning electron microscope (SEM) was used to examine the surface microstructure of the microcapsules. The results revealed that 24% rice starch with 0.30% either carboxymetylcellulose (CMC) or acacia and 22% rice starch with 0.30%gelatin exhibited numerous good appearances of the spherical aggregates. These selected conditions were repeated with glutinous rice starch instead of the regular one. Chemical and physical properties of all products were also investigated, most of which showed a spherical shape under SEM. Concentrations and types of the mixture between starches and binding agents did affect sizes, number and properties of the sphere starch aggregates. The spherical starch aggregates with CMC had a relatively larger in size and number than those with acacia and gelatin. The average sphere diameter of rice starch microcapsules ranged from 15.37-30.19 ∝m, the particle density was about 1.49-1.55 g/cm 3 and the bulk density was 0.540.58 g/cm 3 . Flow characteristics of all products showed easy -to-free flowing powder types. The products possessed moisture content less than 10%, water activity (Aw) 0.20-0.41 and water absorption index (WAI) 0.28-0.70. All samples exhibited hygroscopic properties. Among the samples microcapsule with the best physical properties was made from 24% rice starch with 0.30% CMC. However, the rice starch microcapsules especially with 0.30% acacia possessed higher bulk porosity than the others and gave slightly different pasting properties from the native rice starch.


Blind source separation (BSS) of audio signals aims to separate original source signals from their mixtures recorded by microphones. The applications include automatic speech recognition in a noisy/multi-speaker environment, hearing aids, and music analysis. Independent component analysis (ICA) can perform BSS efficiently, but it is basically inapplicable to the underdetermined case—the number of sources $\boldsymbol{>}$ the number of microphones. In contrast, a BSS approach using the multichannel Wiener filter (MWF) is applicable even to the underdetermined case, but conventional methods based on this approach—including full-rank spatial covariance analysis (FCA)—are highly inefficient. This is because these methods require massive numbers of matrix inversions to design the MWF. To obtain the best of both worlds, we take a joint diagonalization approach: We restrict spatial covariance matrices of all sources to the class of jointly diagonalizable matrices. This enables the above matrix inversions to be replaced by mere scalar inversions of the diagonal elements of diagonal matrices. Based on this, we present FastFCA and FastMNMF—efficient methods for underdetermined BSS. In an experiment, FastFCA was several orders of magnitude faster than FCA without sacrificing separation performance. We also present a unified framework for underdetermined and determined BSS, which highlights theoretical connections between various methods including ours. The efficiency of our BSS methods makes them suitable for large data (e.g., data augmentation for machine learning) or limited computational resources encountered in, e.g., hearing aids, distributed microphone arrays, and online BSS.


We report for the first time a novel rapid synthesis method for manganese oxide (MO) nanoparticles by a reaction between acidic permanganate and poly(dimethylsiloxane) (PDMS). In contrast to the existing traditional methods for synthesis of MO nanoparticles, the new method has the advantage of shorter reaction time (∼2 h) at room temperature (∼25 °C). The produced MO nanoparticles are characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM, HRTEM). The material produced is semicrystalline silicon-doped MnO2 with homogeneous size and morphology with an average particle size around 300 nm. Other products of the reactions include Cl2, silicon dioxide sheets on PDMS, and CO2. A mechanism for this reaction is proposed. The prepared MO was successfully used as a catalyst for the rapid and highly efficient degradation of a water pollutant—Rhodamine B (RhB).

Magnetic flux leakage (MFL) testing is one of the most important methods for tank floor inspection. Traditional transducers were often designed by experiments. Finite element software ANSYS was used to optimize the parameters of the magnetizing system. The circuits for detecting, post-processing and data acquisition were designed, and a transducer were developed. Experiments showed that the transducer had good sensitivity.

We study maximal stretch laminations associated to certain best Lipschitz circle valued maps in Dehn surgery families of hyperbolic 3-manifolds. For these maps, we give a criterion based on the Thurston norm and Dehn filling slope length to determine when such a stretch lamination is a union of Dehn filling core curves. We use this to show there exist infinitely many examples where the homotopy class of the circle valued map includes a fibration and where the laminations have only closed leaves. This gives information about non-maximal horospherical orbit closures in the infinite cyclic covers associated to these fibrations.


In this work we provide a step by step derivation of an angular-averaged Ewald potential suitable for numerical simulations of disordered Coulomb systems. The potential was first introduced by E Yakub and C Ronchi without a clear derivation. Two methods are used to find the coefficients of the series expansion of the potential: based on the Euler–Maclaurin and Poisson summation formulas. The expressions for each coefficient is represented as a finite series containing derivatives of Jacobi theta functions. We also demonstrate the formal equivalence of the Poisson and Euler–Maclaurin summation formulas in the three-dimensional case. The effectiveness of the angular-averaged Ewald potential is shown by the example of calculating the Madelung constant for a number of crystal lattices.


In the present study, the focus was on adolescents' understanding of emotion, including their ideas of emotional competence. In addition, adults' construals of emotion, and emotional competence in children were investigated. Identifying perspectives on factors which influence the development of emotional competence was also attempted. Data generation techniques included conversational-style interactions, termed as active interviews, of individuals and small groups; certain classroom-based written exercises, and enactments followed up with focus group discussions, and incidental observations. Audio recording of the interviews, and field notes were the modes of data management. Analysis of data was approached qualitatively, with a search for themes, in alignment with the objectives of the study. Findings revealed that the adolescents portrayed emotions as subjective experiences with somato-psychic components and behavioral display elicited by, and experienced in, social settings and interpersonal contexts. Familiarity with Hindi emotion terms was amply evident. One's nature or disposition as a contributor to one's emotions and the self was evident in the accounts of older adolescents. Emotional qualities of others have been described as traits and transient displays Emotional competence as characterized by management of emotions was found to be relevant.


In this paper, we present a hybrid method for word segmentation and POS tagging. The target languages are those in which word boundaries are ambiguous, such as Chinese and Japanese. In the method, word-based and character-based processing is combined, and word segmentation and POS tagging are conducted simultaneously. Experimental results on multiple corpora show that the integrated method has high accuracy.

Heat transfer through clothing is an important topic related to thermal comfort in environmental engineering and functional clothing design. The total heat transmitted through clothing is commonly considered as the sum of the dry heat transfer and the evaporative heat transfer. Clothing thermal insulation measured in a nonperspiring con dition, e.g., on a dry thermal manikin, is frequently used to calculate the dry heat transfer when the body is perspiring or even sweating heavily. The effect of perspiration on clothing thermal insulation with respect to dry heat transfer is not well understood, although it is widely speculated that perspiration reduces thermal insulation by wetting clothing assemblies. In this investigation, clothing thermal insulation with very low perspiration and very heavy perspiration is measured using a novel perspiring fabric thermal manikin. Clothing thermal insulation decreases during perspiration, and the amount of reduction varies from 2 to 8%, as related to water accumulation within clothing ensembles. This finding suggests the "after chill" effect of wearers after heavy exercise may not only be caused by heat absorption due to the desorption and evaporation of water within clothing, but also to reduced clothing thermal insulation. Also, for clothing that can absorb a large amount of moisture during sweating, clothing thermal insulation measured on dry manikins may need to be corrected when used for calculating dry heat loss (sometimes used for calculating moisture vapor resistance) on a sweating manikin and predicting thermal comfort during sweating.


The paper relates to the effect of steady-state change of moisture content in timber elements. Several constitutive models of the material used in the literature have been presented. For the purpose of the simulation, a three-dimensional FEM model was prepared. Results were presented based on four models of moisture distribution and three sets of material parameters. Based on the literature and simulation results, the necessity of changing the practical design approach was discussed.


The objective of this work was to evaluate the inter treatment discrimination according to feed conversion efficiency in several animal performance experiments. The variables investigated were: feed conversion ratio (FCR = intake: production ratio), feed efficiency index (FEI = production: intake ratio) and bio-nutritional index (BNI). The BNI was constructed from the first canonical variable obtained based on the multivariate analysis of variance of the intake and animal production (weight gain or milk production) variables. The results indicated that FCR and FEI reciprocated each other at experimental plot level but did not reciprocate at animal group or treatment level. This fact implicates distortions on the descriptive levels of probability of type I error for hypotheses tests and compromises the statistical and animal production inferences. On the other hand, the BNI index guarantees the maximum discrimination among experimental groups and allows to identify significant differences, which were not observe with FCR or FEI indexes. This fact can be associated to the incorporation of animal production intensity characteristics using BNI.

In this review, development of the experimental techniques of ultrasonic spectroscopy made in the past 60 years is briefly recollected. Most of the thechniques belong to one of the four groups evolving from the interferometer, the reverberation method, the pulse method or the Brillouin scattering. The original experiment and the latest technique of each group are introduced. Also dealt with are some fundamental problems inherent in the observation of ultrasonic velocity and attenuation. Brief discussion and comments are given on the problems of uncertainty, spatial wave vs temporal wave, velocity of thermal phonon, and group velocity vs phase velocity.


ABSTRACT Whilst calls for upskilling and retraining the UK construction workforce to meet increasingly stringent energy targets are repeatedly documented in construction strategy and policy reports, it remains unclear how higher education, particularly architecture, is responding. The purpose of this paper is to examine how educators and students across UK architecture institutions view energy-related content in their teaching and learning, and how some of the policy initiatives are being approached. The analysis focuses on what educators and students perceive is being taught and how they evaluate issues that need to be 'upskilled' or 'retrained'. This study draws on evaluative practice literature using multiple data sources including focus groups across UK accredited architecture institutions. The research identifies evaluative perspectives that educators and students draw on to discuss views such as personal interests, institutional sovereignty, experience, physical and disciplinary disconnects and an expectation that 'something will change'. Transforming the status quo is perceived as a major obstacle whereby a school design agenda, design studio educators' motivations and a curriculum that only gets added to are shared concerns. The findings enable foundational discussions that will help define recommendations of required educational approaches to 'upskilling' and 'retraining' in a fast-developing international energy policy agenda.


The basic disadvantage of suspension bridges can be considered their increased deformability. One of the ways to increase the rigidity of a suspension bridge is to transfer a part of stiffening girder rigidity to a suspension cable. A rigid cable better resists the imposed symmetrical and asymmetrical loads and displacements and retains its original geometric form. This paper presents a theoretical investigation of the suspension bridge with the rigid cable. Also, taking into account the geometrical non-linearity of rigid cable behaviour, a simplified analysis method for determination of forces and displacements in stiffening girder and cable of suspension bridge was developed.

The bioflocculant production potential of Bacillus subtilis-2162 was evaluated using standard methods. The bacteria produced an extracellular bioflocculant. Culture conditions for optimal production of the bioflocculants include: glucose and sucrose as carbon sources; multiple + 2 nitrogen sources including: ammonium sulfate and yeast extract; Ca +2 as sole cation source; and initial medium of pH 7. Characterization of the pure bioflocculants revealed that it is thermostable. Hydroxyl, carboxyl and amino groups were also present in the bioflocculant compound as functional groups. The flocculating activity was calculated based on absorbance at a wavelength of 550 nm. Bioflocculant produced in this study is capable of removing heavy metal chromium from synthetic solution effectively. The findings of this study suggest that B. subtilis-2162 holds immense promise as a source of important bioflocculant that could serve as an alternative to synthetic flocculants. Keywords: Bioflocculant, Bacillus subtilis-2162, hexavalent chromium (Cr +6 ), exopolysaccharide


3D Multi-Field Multi-Scale Features from Range Data in Spacecraft Proximity Operations. (May 2012) Brien Roy Flewelling, B.S., Syracuse University Co-Chairs of Advisory Committee: John L. Junkins Daniele Mortari A fundamental problem in spacecraft proximity operations is the determination of the 6 degree of freedom relative navigation solution between the observer reference frame and a reference frame tied to a proximal body. For the most unconstrained case, the proximal body may be uncontrolled, and the observer spacecraft has no a priori information on the body. A spacecraft in this scenario must simultaneously map the generally poorly known body being observed, and safely navigate relative to it. Simultaneous localization and mapping (SLAM) is a difficult problem which has been the focus of research in recent years. The most promising approaches extract local features in 2D or 3D measurements and track them in subsequent observations by means of matching a descriptor. These methods exist for both active sensors such as Light Detection and Ranging (LIDAR) or laser RADAR (LADAR), and passive sensors such as CCD and CMOS camera systems. This dissertation presents a method for fusing time of flight (ToF) range data inherent to scanning LIDAR systems with the passive light field measurements of optical systems, extracting features which exploit information from each sensor, and solving the unique SLAM problem inherent to spacecraft proximity operations. Scale Space analysis is extended to unstructured 3D Dr. Dr.

We humans do many different assessments each day; either through intuition or more strategic where we through deliberate reasoning arrive at answers. The purpose of this study was to examine the link between experts overall evaluations and the same experts criteria based assessments. Data were collected through a web-based questionnaire sent to teachers at Karlstad University where they evaluated new ideas related to education. Answers from 33 individuals where analyzed with a multiple regression analysis and two t-tests. The conclusions are that about 43 % of overall assessments could be explained by the four criteria: Originality, operability, user value for students and user value for teachers. The remaining percentage can be considered intuition as well as other criteria or personal values. Teachers should therefore ponder how they make their assessments and what values they put in addition to the criteria listed in the syllabus.


In this thesis we present two applications of using types of a typed lambda calculus to derive equation schemas, instances of which are provable by convertibility. Part 1: Retraction Approach to CPS transform: We study the continuation passing style (CPS) transform and its generalization, the computational transform, in which the notion of computation is generalized from continuation passing to an arbitrary one. To establish a relation between direct style and continuation passing style interpretation of sequential call-by-value programs, we prove the Retraction Theorem which says that a lambda term can be recovered from its continuationized form via a A-definable retraction. The Retraction Theorem is proved in the logic of computational lambda calculus for the simply typable terms. Part 2: Another look at "Theorems for Free!": We reexamine Wadler's "free theorems"-theorems about polymorphic functions derivable from the type of the function-in an extension of Mairson's syntactic treatment of logical relations. Logical relations are defined as formulas in second (and higher) order logic over untyped lambda terms, from which we can instantiate equations involving a given term. As a consequence we can formulate a free theorem as an equation schema, each instance of which is provable by convertibility, given typing conditions on the terms involved are met. In our framework datatypes are represented as free algebras generated by constants, and we define sufficient conditions which a representation of a datatype must satisfy to preserve free theorems. As a special case we prove examples of free theorems, as equations by convertibility, using BShm-Berarducci representation of datatypes.

Optical refractive index (RI) sensors exploiting selective co-integration of plasmonics with silicon photonics in Lab-on-achip configurations are expected to disrupt Point-of-Care (POC) diagnostics, delivering performance and economic breakthroughs. Propagating surface-plasmon-polariton modes offer superior sensitivity due to their extreme overlap with the surrounding medium. In parallel, low-loss photonics act as the hosting platform with which the plasmonic losses can be sustained while allowing for multiplexed layouts via in-plane SPP excitation schemes. However, merging plasmonics with silicon photonics in a cost-effective manner, requires a truly CMOS-compatible manufacturing process. Herein, we demonstrate experimentally, the highest bulk-sensitivity among all the plasmo-photonic interferometric RI sensors, while taking the leap forward in the development of a CMOS-manufactured plasmo-photonic sensing platform merging Si3N4 photonics and aluminum plasmonics. The proposed structure relies on a butt-coupled interface between Si3N4 waveguides and a 70 μm long plasmonic stripe, deployed in one branch of a Mach-Zehnder Interferometer (MZI) serving as the sensing transducer that detects local changes in the refractive index. The lower MZI arm (reference arm) exploits the low-loss Si3N4 platform to deploy a MZI-based variable optical attenuator followed by a thermo-optic phase shifter to optimize the sensor performance achieving resonance extinction ratio values at the MZI output of more than 35 dB. Experimental evaluation of a gold-based sensor revealed a bulk refractive index sensitivity of 1930 nm/RIU. In addition, we experimentally demonstrate that the proposed plasmo-photonic waveguide platform can migrate from gold (Au) to Aluminum (Al), demonstrating the first step towards a fully CMOS compatible plasmo-photonic interferometric sensor.

We consider an environment where two education institutions compete by selecting the proportion of their funding devoted to teaching and research and the criteria for admission for their students, and where students choose whether and where to attend university. We study the relationship between the cost incurred by students for attending a university located away from their home town and the equilibrium configuration that emerges in the game played by the universities. Symmetric equilibria, where universities choose the same admission standard, only exist when the mobility cost is high; when the mobility cost is very low, there is no pure strategy equilibrium. For intermediate values of the mobility cost, only asymmetric equilibria may exist; the final section of the paper provides an example where asymmetric equilibria do indeed exist for a plausible and robust set of parameters.


Twenty six cultivars of which twenty four local and two introduced (Yellow canary and Lobnani) were evaluated. In order to study the physicochemical quality of melon, a mineral analysis was carried out. This analysis included sodium, potassium, phosphorus and calcium plus magnesium. Na and K were measured by photometer with flame, phosphorus was determined by spectrophotometer and Ca ++ - Mg ++ were proportioned by a proportioning colorimetric. The result showed that all cultivars exhibited the highest level for Na. K content was higher than 2% in 60% of cultivars. P content was higher than 0.1 % in 70 % of cultivars. Ca ++ - Mg ++ content was higher than 1 meq/l in 50% of cultivars. Analysis of variance and hierarchical classification, according to variations in mineral element between cultivars, were assured with SPSS 12.0. Analysis of variance confirmed significant differences (p < 0:05) between the different cultivar for every parameter.


A gold and silicon carbide particle matrix is presented that concentrates light to its surface using a combination of phonon and plasmon resonance mechanisms. The enhanced infrared absorption spectrum of absorbed molecules is used to probe the coupled phonon and plasmon surface resonances. Sensitive molecular detection is achieved by measuring the enhanced infrared absorption or the frequency shift in the surface modes of the coated matrix. This work demonstrates that hybrid polariton resonance structures using metallic and polar dielectric materials are feasible for applications in near-field microscopy, nano-optical devices, and trace chemical sensing.


1.8 A° segment of the Algol A spectrum centered at 1075.55 A° line of Ni II was scanned repeatedely with the 0.05 A° resolution from the Copernicus satellite. The numerical model is described in which 37 out of the total 55 scans obtained during two eclipses were combined in a least-squares solution, to determine the period of rotation and degree of non-solid rotation of Algol A. The period of rotation suggests full synchronism of rotational and orbital motions; the equatorial velocity is V e = 53 ± 3 km/s. The non-solid rotation parameter 's' measuring the distribution of angular velocity versus stellar latitude in ω = ω e (1 - s + s cos 2 ϑ) has been found equal s = 0.07 ± 0.25 indicating the rotation law not far from solid body.


Larvae of lacewings (Neuroptera) are known to be fierce predators. According to the morphology of fossil forms thisseems to have been the case already in the Early Cretaceous. While being predators, lacewing larvae are also food itemsfor other organisms. Here we report two pieces of amber from Myanmar providing instances of such cases. In one amberpiece several isolated stylets of lacewing larvae are preserved closely associated together. The most likely interpretationis that a predator preying on lacewing larvae has regurgitated or defecated these non-digestible pieces, yet the identityof the predator remains unclear. The other amber piece preserves a larva resembling modern day larvae of split-footedlacewings (Nymphidae). The larva has projections on its trunk, allowing it to wear a camouflaging cloak. In the headregion, a mite (Acari) is attached to the larva; more precisely, the entire anterior body region of the mite is apparentlyinserted into the lacewing larva. The mite is smaller than the larva. It is known from the modern fauna that stage 1 larvaeof Ascalaphidae can be attacked also by rather small predators, such as ants. The mite can therefore well be interpretedas a true predator instead of a parasite, especially considering the unusual mode of attachment. We briefly review interactionsof lacewing larvae with other organisms represented in amber from Myanmar and add two new pieces to thepuzzle of reconstructing the trophic interactions in the 100-million-year old amber forest.

Phaseolus vulgaris is a crop widely used in human consumption. Its production is affected by the incidence of biotic and abiotic factors. Genetic transformation provides the possibility of reducing these affections, but the low efficiency in vitro regeneration constitutes a limiting factor for the development of protocols for obtaining plants transformed in this species. The aim of this work was to determine the effect of bacterial suspension concentration, vacuum infiltration time and co-culture on the regeneration of P. vulgaris shoots in 'ICA Pijao' and 'BAT 93' cultivars. Green nodular calli were inoculated with a suspension of A. tumefaciens at a DO 600 0.1, 0.2 and 0.3. Three times of infiltration by vacuum were evaluated: 1, 2 and 3 min and co-culture period of three and five days. The concentration of the bacterial suspension, the vacuum infiltration time and the co-culture period affected the regeneration of shoots of P. vulgaris cv. 'ICA Pijao' and 'BAT 93'. The highest percentages of P. vulgaris shoot regeneration were achieved by inoculating the calli with a bacterial suspension adjusted at DO 600 =0.1, without vacuum infiltration and 3 days in co-culture. The results of this research constitute the first contributions to the scientific community in show the effect of vacuum infiltration on the regeneration of P. vulgaris tissue inoculated with A. tumefaciens . Keywords: co-culture, vacuum infiltration, regeneration, bacterial suspension


AIM: To investigate the role of mitochondrial ceramidase in mitochondrial functions, especially in the regulation of apoptosis. METHODS: pCDNA3.1/His-MtCDase plasmid, containing mitochondrial ceramidase cDNA sequence, was transfected into K562 cells by liposome, and G418 was used to screen the positive clones. A stable transfected K562 cell line was established and defined as 'K562TC'. The differences between K562 and K562TC cells in serum withdrawal resistance and Bcl-2 protein expression were evaluated by annexin V/PI test, flow cytometry and Western blotting, respectively. RESULTS: K562TC cells with elevated Bcl-2 protein expression level identified by FCM or Western blotting showed stronger resistance to apoptosis induced by serum withdrawal than their parental cells. Inhibition of mitochondrial ceramidase expression in K562TC cells by its specific antisense oligodeoxynucleotide was correlated with a decrease in Bcl-2 protein level. N, N'-dimethylsphingosine (DMS), a sphingosine kinase inhibitor, depleted intracellular sphingosine-1-phosphate (SPP) production, also abrogated Bcl-2 protein expression in K562TC cells, while exogenous sphingosine-1-phosphate up-regulated Bcl-2 protein level in K562 cells. CONCLUSION: Mitochondrial ceramidase overexpression in K562 cells leads to markedly elevated level of Bcl-2 protein and results in more resistance to serum withdrawal. This effect is initiated not by sphingosine, the direct metabolite of mitochondrial ceramidase, but via sphingosine-1-phosphate, its phosphorylated form, indicating that mitochondrial ceramidase, through its sphingoid metabolite sphingosine-1-phosphate, up-regulates Bcl-2 protein expression in K562 cells.


Adenovirus is a small DNA tumour virus that has been extensively studied, leading to fundamental discoveries in molecular biology of mammalian cells. In particular, adenovirus oncoproteins were shown to inactivate cellular tumour suppressor pathways and this advanced our understanding of molecular mechanisms of cancer formation. p53 is a key tumour suppressor that ensures cellular genomic integrity. Its function is impaired in most human malignancies, and DNA tumour viruses evolved multiple ways to block p53 activity in favour of productive virus infection. Human adenovirus type 5 codes for two oncoproteins, E1B-55 kDa and E4-34 kDa that bind and forward p53 to degradation in proteasomes. Deletion or mutation of E1B-55 kDa leads to a massive accumulation of the p53 protein in infected cells. Based on this fact, an idea of p53-selective replicating oncolytic virus for cancer treatment was proposed. It was assumed that an infection of cancer cells containing mutant or null p53 with E1B-deficient virus should allow unrestricted virus replication and cell lysis. In contrast, normal cells, bearing wild type p53, were expected to block the replication of such virus mutants, since functional p53 should induce cell cycle arrest or apoptosis after infection. This attractive idea was implemented by the creation of an E1B-55 kDa-deleted oncolytic virus, designated ONYX-015. However, in spite of moderate successes in head and neck cancer treatment, ONYX-015 did not become a breakthrough in tumour therapy. As was shown by numerous studies later, E1B-deficient virus replication was independent of the cellular p53 status, though indeed, the virus replicated better in some cancer cells as compared to normal cells. The reason for ONYX-015 failure was understood on the molecular level, when p53 activity was carefully examined after infection. It became clear that, despite massive accumulation of p53, E1B-deficient virus blocked its transcriptional activity and thus prevented cell cycle arrest or apoptosis induction in the infected cells. Therefore, we speculated that, in addition to E1B-55 kDa, adenovirus evolved back up mechanisms of p53 inactivation that were investigated in this study. First of all, we show here that infection with E1B-defective adenovirus mutants induces massive accumulation of p53, without obvious defects in p53 localization, phosphorylation, conformation, and oligomerization. Nonetheless, p53 completely failed to induce its target genes, e. g. p21/CDKN1A, mdm2, and PUMA. Secondly, we found the adenovirus E1A proteins to be responsible for blocking p53 activity in the absence of E1B-55 kDa. Two regions of the E1A gene products independently contributed to p53 suppression. Depending on the E1A conserved region 3 (CR3), E1B-defective virus blocked transcription of p53 target genes, and impaired the ability of the transcription factor Sp1 to bind the p21 promoter. Moreover, the aminoterminal region of E1A, binding the acetyltransferases p300 and CBP, blocked p53 K382 acetylation in infected cells. Mutating either of these E1A regions, in addition to E1B, partially restored p53 activity. We conclude that adenovirus inactivates p53 by at least two E1B-independent mechanisms. Thus, our study provides a mechanistic explanation why the lack of the E1B-55 kDa cannot be expected to result in p53-selective cytotoxicity. The mechanisms of p53 inactivation by E1A, described here, should be taken into account, when attempting to create p53-selective adenovirus for cancer therapy. Our findings may also help to understand the molecular mechanisms of p53 attenuation by other virus species and by virus-independent cancer cells.


ABSTRACT This paper considers the problem of collision avoidance for road vehicles, operating at the limits of friction. A two-level modelling and control methodology is proposed, with the upper level using a friction-limited particle model for motion planning, and the lower level using a nonlinear 3DOF model for optimal control allocation. Motion planning adopts a two-phase approach: the first phase is to avoid the obstacle, the second is to recover lane keeping with minimal additional lateral deviation. This methodology differs from the more standard approach of path-planning/path-following, as there is no explicit path reference used; the control reference is a target acceleration vector which simultaneously induces changes in direction and speed. The lower level control distributes vehicle targets to the brake and steer actuators via a new and efficient method, the Modified Hamiltonian Algorithm (MHA). MHA balances CG acceleration targets with yaw moment tracking to preserve lateral stability. A nonlinear 7DOF two-track vehicle model confirms the overall validity of this novel methodology for collision avoidance.


The cracking and failure in ceramic substrates during the laser drilling process has been acknowledged as a major problem by designers and manufacturers in the electronic component industries. The cracking and failure is due to large localized thermal stresses within the narrow heat-affected zone on the ceramics. Although the knowledge of the stress distribution in the ceramic substrate is important in understanding and solving the cracking/failure problem, it is impossible to measure the stress directly. The physical parameters of the laser drilling process such as temperatures or displacements, which can be directly related to stresses, can however be measured. That is why, in this research, an electronic speckle pattern interferometer (ESPI) system was designed and used to take speckle pattern images of the ceramic surface during the laser drilling process. Using commercial software, the speckle fringe images were image processed to quantify whole-field transient out-of-plane displacement measurements. A deformation history of the ceramic surface during the laser shaping process with millisecond temporal resolution was obtained, restricted only by the camera frame rate, camera resolution and laser power available. A finite difference model was developed to compare the deformation measurements with the predicted strain calculations. The experimental study and the analysis show that the designed in-situ electronic speckle pattern interferometer system provides an excellent experimental basis for whole- field, transient deformation measurements of ceramic substrates during the laser drilling process.


Abstract The long-wave behaviour of perfectly conducting liquid films flowing down a vertical fibre in a radial electric field was investigated by an asymptotic model. The validity of the asymptotic model was verified by the fully linearized problem, which showed that results were in good agreement in the long-wave region. The linear stability analysis indicated that, when the ratio (the radius of the outer cylindrical electrode over the radius of the liquid film) $\def \xmlpi #1{}\def \mathsfbi #1{\boldsymbol {\mathsf {#1}}}\let \le =\leqslant \let \leq =\leqslant \let \ge =\geqslant \let \geq =\geqslant \def \Pr {\mathit {Pr}}\def \Fr {\mathit {Fr}}\def \Rey {\mathit {Re}}\beta <e$ , the electric field enhanced the long-wave instability; when $\beta >e$ , the electric field impeded the long-wave instability; when $\beta =e$ , the electric field did not affect the long-wave instability. The nonlinear evolution study of the asymptotic model compared well with the linear theory when $\beta <e$ . However, when $\beta =e$ , the nonlinear evolution study showed that the electric field enhanced the instability which may cause the interface to become singular. When $\beta >e$ , the nonlinear evolution studies showed that the influence of the electric field on the nonlinear behaviour of the interface was complex. The electric field either enhanced or impeded the interfacial instability. In addition, an interesting phenomenon was observed by the nonlinear evolution study that the electric field may cause an oscillation in the amplitude of permanent waves when $\beta \ge e$ . Further study on steady travelling waves was conducted to reveal the influence of electric field on the wave speed. Results showed that the electric field either increased or decreased the wave speed as well as the wave amplitude and flow rate. In some situations, the wave speed may increase/decrease while its amplitude decreased/increased as the strength of the external electric field increased.

Basically the amplifier is amplifying and enlarging the input signal. The input signal is copied and then rearranged into a reinforced signal, as it is well known that the audio amplifier types consist of Class A, Class B, Class AB and Class D amplifiers. In class D amplifiers have the advantage of great power efficiency (Can reach approximately 90%) when compared to other amplifier (class A, class B and class AB amplifier) so that the generated power efficiency is large. With the above problems, this study aims to compare Class D amplifier with 3 pairs of different Power Mosfets, IRFP4227, IRFP250N and IRFP460. The class D audio amplifier is a digital amplifier based power amplifier using the Pulse With Modulation (PWM) system where the input signal will be processed into a digital signal which will then be reinforced and reworked using a Low Pass Filter (LPF). The concept used in this audio amplifier D is self oscilating, that is by means of the internal loop feedback obtained from the R-C circuit so as to make the circle oscillate by itself. This study compared 3 pairs of Power Mosfet by using power supplay equal to 112,64 watt at Power Amplifier. After several test of Power Mosfet get data as follows: IRFP4227 power output of 96.01 watts with an efficiency of 85.24%, for IRFP250N of 94.06 watts with an efficiency of 83.50% and IRFP460 of 73.07 watts with efficiency 64.87% at the input signal of 1 KHz and at 8 Ω. In addition, the total harmonic distorsion (THD) in IRFP4227 is 0.78%, IRFP250N is 1% and IRFP460 is 1,65% and also the Signal to Noise Ratio (SNR) on IRFP4227 is 103,75 dB, IRFP250N is 102, 74 dB and at IRFP460 of 97.29 dB.


of Dissertation Presented to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Master of Science EMBEDDING RADIO FREQUENCY IDENTIFICATION INLAYS INTO INJECTION MOLDED FOOD CONTAINERS USING IN MOLD LABELING TECHNOLOGY By Alexis Michelle Chalfant December 2007 Chair: Jean-Pierre Emond Major: Agricultural and Biological Engineering RFID technology is slowly becoming a strong presence in the food packaging industries. The tracking and tracing capabilities that go along with RFID are making it an indispensable tool in any industry, let alone in the food industry where recent food scares have made the concept of product origins a highly desirable addition to any food product. Large organizations are committed to the use of this technology throughout open supply chains, and the focus centered on this technology has shifted from pilot and lab testing to full on implementation. As more companies adopt RFID usage, the costs of the technology, one of the biggest limiting factors, will decrease steadily and promote a movement to item level tagging. Item level tagging is where most benefits to the consumer can be seen. Embedding RFID tags into individual injection molded containers was studied. The main objective was to develop a method for embedding RFID inlays into injection molded packaging using IML technology. Preliminary tests were run on establishing the effects of adding PETE to a PP matrix and IML film. Using the results from these preliminary tests, a process of holding an RFID inlay to an IML film using 2 different adhesives was developed and tested using 3 different inlay styles supplied by Avery Dennison (South Carolina, USA). In order to determine the best method for application, the inlays were studied with adhesives applied as follows: 1) to

It consists in removing the excess water and nitrogenous toxic substances from the blood, which is diverted to an appliance, a dialyzer to remove toxins and the blood is returned to the patient's body. The dialyzer functions as an artificial kidney, acting as a semi-permeable membrane to replace the glomeruli and renal tubules, as a filter to the kidneys due to bankruptcy renal excretory mechanisms in patients with chronic and acute kidney disease. 1 Although prolong life even indefinite, hemodialysis does not replace entirely the function of the kidneys and the patient continuously is subject to different problems and complications, among which: hypotension; painful muscle cramp, belatedly to dialysis; exsanguination; arrhythmias; air embolism; chest pain in patients with anemia or arterio-sclerotic heart disease. 1 In addition, dialysis results in changes in the lifestyle of the patient and his family, and may generate conflict, frustration, guilt and depression. Vascular access care is also a key element being the educational process of fundamental importance for the prevention of complications. On this basis, the nursing staff has the monitoring function, support, assessment, and patient education, maximizing their potential vocations, functional status and quality of life. To this end, it is important to provide patients with an environment in which they can express their feelings and their reactions. Nursing care, the essence of the profession, belongs to two spheres: an objective which corresponds to techniques and procedures, and a subjective, based on feelings, such as sensitivity, creativity and intuition. Thus, there is only caution when both are used appropriately and combined with the technology. The nurse has great acting and autonomy and to manage and provide quality care to patients, is required constant updating and preparation, to ensure safety and psychological comfort procedure, due to the changed quality of life. Furthermore, scientific research in the area is an essential instrument for systematization of nursing care in haemodialysis. In the meantime, the idea of technology is associated with not only the technological equipment but also to knowledge, which give meaning to the instrumental reason of equipment. With this, the technologies involved in health work as light are classified, which consists in establishing relationships as: autonomy, reception and management of services; light-hard when it comes to structured knowledge as theories or models of care, the medical clinic, the psychoanalytic clinic and epidemiology; and hard, when they involve instruments and technological equipment as machines and standards. On this basis, technology can act as a mediator of objectivity and subjectivity of care, ensuring that sense and sensibility to act together as strengtheners instruments of nursing actions based on the needs of the patients of hemodialysis, as support, evaluation, emotional support and education. Care therefore requires combining processes, products and technological expressions of knowledge. On the relevance of the topic and the scarcity of studies that show the application of different modes of light technologies and light-hard in the nursing care to patients in hemodialysis, it was delimited as subject of this integrative review the use of the technologies on patient care in hemodialysis. ● To analyze the domestic content produced on hemodialysis technologies, highlighting the dimension of nursing care to these patients and the use of these technologies to prevent potential complications of therapy. Integrative review of literature about the knowledge produced about hemodialysis care technologies, seeking to answer the following research question << which technologies have been involved in nursing care to patients on hemodialysis in the Brazilian scenario?>> The integrative literature review consists of a search, which allows the synthesis of knowledge from analysis of published studies, supporting the elaboration of general conclusions of knowledge in a particular area of study.
