The purpose of this paper is to obtain a better understanding of how leadership is enacted by hybrid doctor-managers (DMs) as well as what engagement strategies hybrid doctor-managers use with their clinical colleagues that may influence organisational objectives being met. This paper provides empirical insights into how hybrid doctor-managers, in their leadership role, engage with their clinical colleagues. The findings suggest that in only a few cases, doctor-managers combine both their organisational and clinical leadership role. As clinical experts, they naturally take on a clinical leadership role, but many fall short in also taking on a managerial leadership role, working towards organisational objectives, such as meeting the key performance indicators, promoting an efficient use of resources and leading organisational change initiatives. We also found that doctor-managers do not have clear role descriptions and that doctors lack managerial qualifications.


512. Diet Calculation In Diabetes Mellitus. R. C. WINN (.led. Journ. of Australia, 'March 5th, 1927, p. 321) suggests a way of simplifying the dietetic treatument of diabetes mellitus without sacrificing any essential priniciples. By muultiplying the patient's weight in pounds by twelve the num-ber of necessary calories required in the diet is ascertained, and by using varying comiibinations of three "diet groups" (of 500, 600, and 900 calories) different diets containing any desired number of hundreds of calories can be prescribed. 't is claimed as an advantage over the Lawrence line-ration scheme that the combination of " diet groups " is easy of calculation, and that the completed (liet will never contain a smallex quantity than half an ounce of any foodstuff. On the diet prescribed very light work is allowed for a week, when the same diet is continued if sugar is still present though reduced in quantity, while if there is no reduction

This article reports on the increasing use of multimedia and computer graphics technologies by British water companies, to keep sewerage records up to date and reduce maintenance problems. Accurate records have become more important, since the 1989 Water Act requires water companies to maintain sewerage records. In the three and a half years since water was privatised in the UK, there has been growing awareness of the advantages of using advanced computing methods for all areas of management. These technologies enable faults to be anticipated before major and expensive crises occur, by: (1) better record maintenance; (2) closed circuit television (CCTV) surveying; and (3) improved storage of and access to data. Better surveying techniques allow the more effective application of other technologies, such as cheaper no- dig methods. Pictorial informaiton and images can be used to monitor the accuracy of coded data, and help to decide which areas or pipe lengths should be surveyed to check for deterioration. Vast amounts of information are already required for and generated by CCTV surveys. Multimedia facilities allow moving images to be captured on computers, and data compression techniques enable computers to store more of these images. Further improvements are still required and are in progress.


The utility model relates to a tool type concrete beam static force loading device, which belongs to a civil engineering field. The loading device is mainly used for long-term loading test of the concrete beam, and can be used to reinforce the strengthening beam and to operate the loading test to imitate the work condition in the practical engineering on the premise of keeping the vertical load constant. The utility model comprises a counter force frame at the bottom and a loading pull rod, wherein the counter force frame comprises two channel steels, a reinforcing rib and a gusset plate, a round rod supporting seat, a concrete beam test piece, a round rod, an allocation beam, a steel backing plate and a nut are arranged on the counter force frame from bottom to top; one end of the pull rod with a force gauge is positioned on the bottom steel beam, the other end with a screw thread and a nut is screwed above thereof. Because the loading device belongs to a self-balancing loading system, the loading device has the advantages of simple structure, small floor area, reusable and removable, convenient charge control, accurate and reliable data detecting, fully meeting the charge requirements of the long-term under stress performance test of the concrete beam and the short-term load-holding reinforce test.


Conflict in creative work is sometimes thought to emanate from the contentious personalities of creative workers. Drawing on several months of ethnographic field work at an advertising agency and semi-structured interviews with advertising professionals, I propose an alternate explanation for this antagonism, grounded in creative workers' and their market-oriented colleagues' competing definitions of good work. As an illustration of this larger struggle, I focus on the tension that arises during creative assessment. I find that while creative workers designate ideas as "creative" based on novelty and relevance, not all sources of novelty and relevance are considered legitimate. Sources that originate from outside their professional domain are dismissed as not novel (e.g., "overused") or irrelevant (e.g., "constraints"). Consequently, I suggest that creative assessment can be understood as a form of professional boundary work, a conceptualization with implications for our understanding of conflict in the creative workplace and the evaluation of creativity more generally.

Abstract The pure rotational spectrum of magnesium sulfide has been measured with a cavity pulsed microwave Fourier transform (MWFT) spectrometer, as a test of a new laser ablation source. The J = 1–0 transition near 16 GHz has been measured for 4 isotopomers in the ground vibrational state, as well as for the main isotopomer, 24 Mg 32 S, in the first excited vibrational state. 25 Mg nuclear hyperfine structure has been observed and the nuclear quadrupole coupling constant, eQq ( 25 Mg), has been determined. A value for the equilibrium bond length has been obtained.


This paper presents a method for automatically extracting a scene depth map and the alpha matte of a foreground object by capturing a scene through RGB color filters placed in the camera lens aperture. By dividing the aperture into three regions through which only light in one of the RGB color bands can pass, we can acquir three shifted views of a scene in the RGB planes of an image in a single exposure. In other words, a captured image has depth-dependent color misalignment. We develop a color alignment measure to estimate disparities between the RGB planes for depth reconstruction. We also exploit color misalignment cues in our matting algorithm in order to disambiguate between the foreground and background regions even where their colors are similar. Based on the extracted depth and matte, the color misalignment in the captured image can be canceled, and various image editing operations can be applied to the reconstructed image, including novel view synthesis, postexposure refocusing, and composition over different backgrounds.


Let T be a strong tournament of order n≥4 with diameter d≥2 . A vertex w in T is non‐critical if the subtournament T−w is also strong. In the opposite case, it is a critical vertex. In the present article, we show that T has at most max{2,d−1} critical vertices. This fact and Moon's vertex‐pancyclic theorem imply that for d≥3 , it contains at least n−d+1 circuits of length n−1 . We describe the class of all strong tournaments of order n≥4 with diameter d≥3 for which this lower bound is achieved and show that for 2h≤n−d+1 , the minimum number of circuits of length n−h in a tournament of this class is equal to n−d+1h . In turn, the minimum among all strong tournaments of order n≥3 with diameter 2 grows exponentially with respect to n for any given h≥0 . Finally, for n>d≥3 , we select a strong tournament Td,n of order n with diameter d and conjecture that for any strong tournament T of order n whose diameter does not exceed d, the number of circuits of length ℓ in T is not less than that in Td,n for each possible ℓ. Moreover, if these two numbers are equal to each other for some given ℓ=n−d+3,...,d , where d≥(n+3)/2 , then T is isomorphic to either Td,n or its converse Td,n− . For d=n−1 , this conjecture was proved by Las Vergnas. In the present article, we confirm it for the case d=n−2 . In an Appendix, some problems concerning non‐critical vertices are considered for generalizations of tournaments.

2 ||| 1556-6072/19©2019ieee ieee vehicular technology magazine | march 2019 T he majority of existing wireless communication systems relies on training-based signaling, i.e., schemes that rely on accurate channel estimates for detecting the transmitted symbols. Training requires its own hardware and algorithms and consumes a significant portion of the channel coherence interval, which is typically short in vehicular communications. The drawbacks of training can be alleviated by using noncoherent signaling schemes, which dispense with the training phase altogether. We will focus on a particular class of such schemes, i.e., Grassmannian signaling. This scheme is optimal for high signal-to-noise ratio (SNR) communication over noncoherent block-fading channels, which are likely to arise in many future networks. Training-based signaling requires the receiver to obtain reliable channel estimates prior to detecting the transmitted symbols [1]. However, when the number of wireless nodes becomes large, as in the prospective paradigms of machine-type communications (MTCs) and the Internet of Things (IoT), acquiring channel estimates constitutes a formidable task, especially for multipleinput, multiple-output (MIMO) systems. For these paradigms, a viable alternative is offered by noncoherent signaling, which does not require the receiver to have access to channel estimates. In comparison with their training-based counterparts, noncoherent schemes feature several advantages. First, they dispense with the hardware and the algorithms required for learning the channel. To appreciate this, we note that, for the urban microcell (UMi) long-term evolution (LTE) scenario of a user terminal operating at 1.8 GHz and traveling at 25 km/h, the channel coherence time is about eight symbol durations of 71.4 s n each. Using a four-antenna 3rd Generation Partnership Project training-based system to communicate in this scenario consumes 14.3% of the resources for training [2]; a cost that can be avoided by noncoherent signaling. Second, noncoherent schemes offer the potential of achieving higher spectral efficiencies. We will elaborate on this aspect later in this article. Third, noncoherent signaling alleviates one of the key problems that arise in massive MIMO cellular systems. In these systems, each base station (BS) is equipped with a large number of antennas, whereas the users are each equipped with a small number of antennas. When training-based schemes are used in the uplink of these systems, multiple neighboring cells will reuse the same training pilots. The received signals corresponding to these pilots interfere, resulting in pilot contamination. Hence, using noncoherent signaling in Digital Object Identifier 10.1109/MVT.2018.2866306


Freeze-dried products are food products prepared by using the freeze-drying method. Freeze-drying is a technology of removing water from fresh products by vacuum method. In the production of food products it allows almost completely preserve their nutrients, vitamins, minerals, even the original form, natural smell, taste, color under a various of storage conditions. During the drying process, the residual water content reaches a value of about 10%. For safe and secure preservation of dehydrated products, it is necessary to sterilize them and the package proper during the packaging process. For the purpose, it is convenient to use a pulsed gas discharge, which will be ignited inside the package during the vacuuming process. The pulsed nature of the discharge provides high efficiency of creating sterilizing agents in the form of ozone and ultraviolet radiation at low heat deposition. Air exhaust removes gaseous reaction products caused by the discharge. The porosity and dielectric properties of freeze-dried products provide high quality sterilization.


By utilizing the two waste heat sources from the positive-displacement engine (106), a method for operating a cascaded organic Rankine cycle (ORC) system (100) and the system is used, the engine (106) and cascaded ORC system (100 efficiency of) rises. Hot waste heat source from the positive-displacement engine (106) is utilized in the first ORC system (102), evaporate the first working fluid (118). Cold waste heat source from the positive-displacement engine (106) is used in the second ORC system (104), heating the second working fluid (130) to a lower temperature than the evaporation temperature. The second working fluid (130) is vaporized using the heat from the first working fluid. In one embodiment, the positive-displacement engine (106) is a reciprocating engine. Hot waste heat source may be an exhaust gas, low-temperature waste heat source can be a jacket cooling water.


Thresholds are commonly used in condition monitoring and fault diagnosis of gas turbine engines as they are the criteria for health status discrimination. We discover that most thresholds should be varying according to gas turbine working condition, but many traditional fixed threshold designs didn't consider this and therefore can potentially be replaced with dynamic ones for higher monitoring precision. In this paper, we propose an objective function that can be applied in any neural network model to learn to output a set of parameters for a distribution based on the maximum likelihood theory, and a matching dynamic threshold determination method for health state discrimination in example of a residual-based monitoring approach. The proposed methods are examined progressively with simulated data and finally an industrial gas turbine failure case. Results show that 1) the proposed objective function can learn the parameters of the distribution well; 2) the dynamic thresholds can effectively reduce the false-positive and false-negative rates when there is a varying noise comparing to fixed thresholds.


A sequential tuning technique for coupled resonator filters using the Hilbert transform derived relative group delay is demonstrated. It is shown that the S21 group delay contains sufficient information for filter tuning and that this group delay can be derived from the magnitude of S21 using the Hilbert transform. This technique allows for the cost of the required tuning hardware to be decreased by an order of magnitude compared to a complete VNA setup. Measured results for the tuning technique using a 3-pole 3% bandwidth filter at 14GHz are shown with an achieved return loss of 13dB demonstrating the usefulness of the technique for coarse filter tuning.

A new bitter glucoside, named aloenin, isolated from Aloe species has been established to be 2-(carbomethoxymethyliden)-4-(β-D-glucopyranosyloxy)-7-hydroxy-5-methylchromene (1). This is an unique example of naturally occurring chromene having the carbomethoxymethylidene group on C-2.


This paper is an attempt to study the fire performance of concrete filled steel tube reinforced concrete (CFSTRC) columns exposed to fire condition. Tests were carried out on CFSTRC columns subjected to ISO-834 standard fire. Details of temperature distribution, fire resistance, deformations and failure mechanism are presented in the paper. Based on the observation and analysis of test results, the characteristics of CFSTRC columns subjected to a fire were investigated. It was found that the concrete outside CFST can act as a natural insulation to the steel tube and the inner concrete; there was no local buckling in steel tube due to the presence of concrete both outside and inside steel tube; the concrete inside steel tube kept intact in the test. These characteristics make CFSTRC columns obtain a favorable fire performance. A three-dimensional finite element analysis (FEA) model was developed to calculate the temperature field of CFSTRC columns. Based on theoretic analysis, the influences of important parameters on the temperature field of the composite columns were investigated. The studies in the paper will be a foundation for further theoretical analysis on the mechanic performance of CFSTRC columns exposed to fire.


Recent work with simple idealist models and based on ice core data (von der Heydt et al. 2014) has suggested that the fast (Charney) climate sensitivity can vary considerably during the last glacial-interglacial cycle with substantial differences between glacial and interglacial states. We investigate this further using a suite of 62 simulations of the last glacial interglacial cycle, using a fully coupled atmosphere-ocean model (HadCM3). The original simulations use orbital, greenhouse gases and ice sheet boundary conditions appropriate for various time periods throughout the last 120 kyr BP (sampling at 1 kyr BP simulations from 21 kyr BP, reducing to 4 kyr BP sampling at the last interglacial). We have repeated these simulations, quadrupling CO2 for each period. We quantify the implied climate sensitivity using Gregory plots. The results show that fast climate sensitivity can vary by more than 40% depending on the background climate state. However, within the model it is not just a simple function of glacial versus interglacial climates, but is strongly influenced by regional forcings from the ice sheets. The mechanisms of changes will be discussed as well as the implications for palaeo estimates of climate sensitivity.


INTRODUCTION
The organisation and the reimbursement pattern for surgery in Denmark are relatively unknown.

MATERIAL AND METHODS
The organisation and activity of hip and knee replacement, laparoscopic cholecystectomy and inguinal herniotomy, low-back surgery and obesity surgery were analysed together with the surgery reimbursement pattern in Denmark in the 5-year period 2004-2008 based on national register data.

RESULTS
During the 4-year period 2004-2007 activity rose for all types of surgery, except laparoscopic cholecystectomy. A predominant part of the increased activity was seen within the private sector, especially in obesity and low-back surgery. A predominant part of the activity in the private sector was financed via public sector funding.

CONCLUSION
The results show increased surgical activity in five common operations and call for intensified monitoring of activity and quality to secure research and further development on a nationwide basis.


The Coalition Provisional Authority (CPA) in Iraq was a civilian administration conjured up from almost nothing after the initial conflict was already over. It was inevitable that it should have suffered from grave shortcomings in management, organisation, staffing, direction and resources. But some of these were avoidable. While governments and the headquarters in Baghdad focussed on high political and constitutional mafters and the organisation of large-scale contracts, CPA staff on the ground elsewhere faced very different challenges with which they were ill equipped to deal. The prevailing security environment was the key to all other activity, but there was a close relationship between this and progress over reconstruction, the development of local as well as national government, and the perceptions of the Iraqis.


Present study was carried out in P.D.U. hospital, Rajkot for time period between October 2012 to June 2014. The study was conducted on the indoor and outdoor patients having clinically suspected malaria. The diagnosis of malaria was established by thin blood smear, thick blood smear and antigen card test. Then haematological changes were studied by automated cell counter and peripheral smear examination, in these diagnosed cases of malaria which concluded that anemia and thrombocytopenia and mild rise in ESR where significantly associated with malaria while WBC count has no statistic significant. Blood indices also do not show any correlation with malaria.

THE birth to a queen of England of a surviving child has, for the most part, been an event accurately recorded by contemporary chroniclers for the last 500 years. But if the child did not survive, detailed information was often lacking; the sex was generally stated, but whether the infant was stillborn or died soon after birth, whether "soon after birth" meant hours or days, and whether the birth was premature or not, are matters about which precise information is often not available. If the queen miscarried, the documentation of the event was even less reliable, for a variety of reasons. The term "miscarriage" was, in former times, not used as we would use it now to refer to the expulsion of the child from the womb before twentyeight weeks of pregnancy, but was very loosely used to describe the birth of a dead child whether this occurred before or after viability. Thus a queen might be reported to have miscarried when, in reality, she had had a premature stillbirth. Second, if the miscarriage had been very early in pregnancy, as many are, the physicians might have been uncertain that a miscarriage had actually occurred or, if they were certain, the event may not have been announced outside the immediate family circle. Third, any indisposition the queen may have suffered was believed to be concerned with a pregnancy; when no child was subsequently born, it was concluded that she must have h'ad a miscarriage. Very soon, the conclusion that she "must have had" became an assertion that she "had" miscarried. Historians, sometimes of the highest repute, and other historical writers have tended to accept such evidence somewhat uncritically, so lending the weight of their authority to what was initially mere rumour. Two of England's queens who have particularly suffered in this respect are Catherine of Aragon and Anne Boleyn. A close examination of the evidence does not suggest a series of miscarriages in either, as has been commonly asserted. Catherine of Aragon's childbearing history has been variously reported by historians. Scarisbrick1 credits her with "several miscarriages, three infants who were either stillborn or died immediately after birth (two of them males), two infants who died within a few weeks of birth (one of them a boy) and one girl, Princess Mary"; this must mean a total of at least nine pregnancies since "several miscarriages" can hardly


The fluid flow and suspension characteristics inside small-scale, stirred, single-use bioreactors were investigated experimentally and by means of computational fluid dynamics. The required impeller speeds for homogenous suspension were determined for two microcarrier types. The shear stress level and turbulence distribution were predicted using a numerical model, which was verified by particle image velocimetry measurements. In subsequent cultivations of primary mesencymal adipose-derived stem cells, up to 31.4-fold expansion in cell number was achieved for serum concentrations as low as 5 %.


The focus of this study is the examination of the effects of perceived sacredness of a particular consumer ritual on consumers' level of "play" and enduring involvement. In this study, the sociological concept of "play" is operationalized as flow, communitas, and ecstasy. We also examine the relationship between the components of play and enduring involvement and how play can serve as a mediator. In a study of experienced golfers, play is found to mediate the relationship between the perception of golf as being sacred and one's enduring involvement in the game.


We report updated results for the first 7 yr of our programme to monitor 27 galaxies within 10 Mpc using the Large Binocular Telescope to search for failed supernovae (SNe) – core collapses of massive stars that form black holes without luminous SNe. In the new data, we identify no new compelling candidates and confirm the existing candidate. Given the six successful core-collapse SNe in the sample and one likely failed SN, the implied fraction of core collapses that result in failed SNe is f=0.14^(+0.33)_(−0.10) at 90 per cent confidence. If the current candidate is a failed SN, the fraction of failed SN naturally explains the missing high-mass red supergiants SN progenitors and the black hole mass function. If the current candidate is ultimately rejected, the data imply a 90 per cent confidence upper limit on the failed SN fraction of f < 0.35.


In recent years, public interest in aged apartment remodeling has come to rise in Korea with the government's strict regulation to restrict apartment reconstruction. To meet the rising demands on apartment remodeling, we attempt in this paper to develop an analytical research and schematic application of extension types for domestic apartment building stocks. Our research adopts a typological approach, as Korean apartments have developed in a way that some prevalent standardized patterns are obvious in them. In order to provide an overview of the recent development of apartment remodeling in Korea, we firstly investigate the housing unit plans of apartments in Seoul and classify them into groups to extract the typical configurational patterns of them. Next, we examine apartment remodeling projects developed so far to explore the current trends in practice, and analyze them to extract and structuralize the technical elements used in them for remodeling. From the extracted technical elements, we draw out the four main extension remodeling types from which we develop the schematic models for the selected example plans, which proved to be the most prevalent types of the current domestic apartments in the preliminary survey. From the schematic development of the models, we finally draw out and discuss the technical problems we have to tackle in implementing apartment extension.


Ti vapor is produced in a He buffer gas. Ti metal is irradiated by a pulsed YAG laser, and its vapor is optically pumped by a N2 laser at 337 nm. Laser lines at 551.4, 472.3, and 471.0 nm from the Ti 3D01 level which is connected to the ground state by the 337‐nm resonance line. Laser lines are reported for the first time at 551.5, 551.3, 431.5, and 547.4 nm from the 3D02, 3D03, or 3G05 levels which are not optically connected to the ground state by the 337 nm line. The laser transitions from the 3D02, 3D03, or 3G05 levels are observed only in a He‐Ti mixture.

1 Professor, 2,3,4 Senior Resident, 5 Professor and Head of Department Department of Pathology, MGM Medical College, Navi Mumbai, India Corresponding Author Dr Mithila K.B Resident Department of Pathology, MGM Medical College, Navi Mumbai, India Email: firstname.lastname@example.com Ph No. 9594652109 Abstract More than one million deaths amongst worlds women population every year are attributed to carcinoma cervix. In India over a lakh women are diagnosed with cervical cancers each year of which nearly 50 % succumb to death. Cervical cancer is the second most common carcinoma seen in 15-44 years age group which if diagnosed early and treated the morbidity can be reduced by 70% and mortality by 80%. Cervical smear is a sensitive, simple, safe, noninvasive and effective method for detection of pre-cancerous and non-cancerous changes. Aim: The objective is to study the role of pap smear in diagnosing premalignant and malignant as well as nonneoplastic lesion of the cervix and to determine the incidence of various lesions. Material and Method: A retrospective study of six months on Pap smears examination was carried out in cytopathology section in Central Laboratory of MGM Medical College Kamothe. Around 701 smears were studied ranging from 18-90 age group. The smears were taken with sterile Ayers spatula. Materials were smeared on a pre labelled glass slides to form a monolayer thick smear. Slides were fixed with methanol, which after drying were stained by rapid pap method. Result: A total of 701 cases were screened there were 582 abnormal pap smears with 119 normal pap cases 24 cases were inadequate for opinion, 468 showed inflammation 29 cases of atrophic smear 2 cases of HSIL and 3 of LSIL, 4 cases of CIN 1, 22 of candida, 3 suspected cases Chlamydia trachomatis, 4 of AGUS,16 of bacterial vaginosis and 6cases of trichomoniasis were seen in the smears studied. Conclusion: Incidence of malignancy can be prevented by pap screening programmes. Pap smear helps in early detection and management of malignancies hence reducing mortality and morbidity. Pap smear studies are cost effective, doesn't need experts and specialists for collection. Therefore, till today it is the most useful screening procedure for malignant and pre-malignant conditions.


A novel technique to enhance the performance of coupled microstrip lines (CML) is proposed by incorporating the structure of split ring resonators (SRR). The structure of CML which is conventionally designed on a grounded dielectric substrate is reconstructed by inserting the structure of SRR between the lines and the groundplane. This construction is expected to improve the performance of CML, i.e. reflectivity, transmittivity, and cross-talks. The number of SRR incorporated in the structure is limited into 4 pieces per line due to the available of space. The proposed structure of CML with SRR is then deployed on 2 stacked layers of FR4 Epoxy dielectric substrate with the total thickness of 1.6mm and the dimension of 36mm × 80mm. Prior to the hardware realization, the geometry of SRR is investigated numerically to obtain the optimum performance of coupled microstrip lines. From the results, it shows that the measured results for Snn and Snm are comparable to the numerical ones obtained from simulations. The reflectivity, Snn, for each port is less than -20dB, while the transmittivity, Snm, is closed to OdB. The measured results also show that the near- and far-cross-talks are -30dB and -35dB, respectively.

The effect of porosity on the complex dielectric permittivity of microwave sintered zinc oxide at room temperature and 2.45 GHz is reported. The predictions of conventional Maxwell–Garnet theory and the effective medium approximation are in poor agreement with the experimental results. Various methods are employed to investigate the system in an effort to come up with new mixing laws, including combinations of these two analytic theories and finite difference electromagnetic simulations of representative microstructures. A model that assumes the existence of dielectrically inactive, fractal‐geometry boundaries between ceramic grains provides an excellent description of the results with no free parameters. It gives physical insight into the experimentally observed mixing law.


19th biennial IPEG Meeting: Nijmegen, The Netherlands. 26-30 October 2016. Our motivations influence our actions in predictable ways. The promise of a reward promotes behavioural activation, while the threat of a punishment context promotes inhibition. However, these motivational biases can at times be at odds with our goals. At such times, we need to be able to suppress them, which has been suggested to be implemented by the midfrontal cortex. We developed a novel paradigm and computational models of behavior to disentangle the impact of such motivational response biases, from the impact of learning from reward and punishment outcomes. Participants (N = 34) completed this task while recording surface EEG. As expected, cue valence strongly biased action. Midfrontal theta-band oscillatory activity was increased in those trials, where the motivational response bias conflicted with the required response, particularly when subjects successfully suppressed the motivational bias. We will present further analyses to dissociate the role of midfrontal cortex in learning from reward and punishment outcomes. This work will allow us to characterize how motivations drive biases in both choice and learning, and how we may learn to suppress these when they are at odds with our instrumental goals. This work has relevant implications for a range of psychiatric disorders associated with a maladaptive reliance on impulsive, motivationdriven responding including addiction, impulse control and ADHD.


This book on the ethical and legal issues which are raised by research with Alzheimer patients, had its origins in a conference at the Queen Elizabeth Hospital in Toronto in January 1989. The book is about the social contract between physicians who feel compelled to do research on Alzheimer's disease by its devastating natureand the victims of the disease who are their subjects. The participating clinical investigators sought the advice and comment of six distinguished ethicists and jurists. Thirty-eight individuals have contributed portions of 20 carefully edited chapters, according to a plan which has avoided at least some of the hazards of multiple authorship. The primary prospective audience is other clinical investigators. The first two chapters set the general framework of the ethical and legal issues about research on patients with Alzheimer's disease. In a calm judicious style, general principles are introduced about why research is important and why there are special problems with treating Alzheimer patients fairly and with respect to their rights as human beings.


Figure 1: Laser light is evanescently coupled into a microtoroid whispering gallery mode (WGM) and confined to the microtoroid's outer boundary where optical absorption and heat generation takes place (red glow). This increase in temperature causes superfluid helium to flow up the pedestal towards the heat source (thermomechanical effect, blue arrows). At the level of the heat source, superfluid helium is converted into the gas phase (red arrows).


The present article analyzes the impact of Winter Sonata (a South Korean television series) and hanryu phenomenon -- the current fad for pro-South Korean popular culture -- on Korean residents in Japan (referred to as "Zainichi Koreans"). Considering Zainichi Koreans as a unique audience set for Winter Sonata and hanryu culture, the study offers an interpretive analysis of the qualitative data collected from Zainichi Korean viewers of Winter Sonata. Our study reveals that consumption of hanryu and Winter Sonata shifts the position of Zainichi Koreans from being invisible minorities to visible ones.


One of the decisive reasons for the slow market penetration of electric vehicles is their short driving range, especially in cold temperatures. The goal of this paper was to increase the driving range in cold temperatures. Electric vehicles recover kinetic energy by recuperation and storage in the battery. However, if the battery is fully charged or cold, the option of recuperation is severely limited. Braking energy is dissipated into the environment via the mechanical brake, and the range thus decreases. Electrothermal recuperation (ETR) enables the braking power to be used in heater systems and thus saves energy in the overall system. In this paper, ETR was investigated with a highly responsive serial layer heater. An overall model consisting of the electric powertrain, the heating circuit, and the vehicle interior was developed and validated. The limitations of recuperation capability were determined from driving tests. The factors state of charge and battery temperature were varied in the conducted simulations in order to quantify the range increase through ETR. The results showed that the range could be increased via electrothermal recuperation by up to 8% at −10 °C in a real driving cycle, using a serial heater. A control strategy of the heating circuit enabled the coolant circuit to function as buffer storage. The interior temperature—and consequently user comfort—remained unchanged.


The molecular orbitals of diborane have been calculated by the nonempirical SCF‐LCAO method, taking all electrons of the molecule into account and calculating exactly all the integrals. The basis functions were Gaussians centered on the various atoms of the molecule. Two sets of Gaussians have been used, the largest one containing 54 functions, distributed as follows: 9s+3p on each boron, and 3s on each hydrogen. The ordering of the molecular orbitals on the energy scale agrees with that found by Newton, Boer, Palke, and Lipscomb who have used an almost optimized minimal STO basis. The calculated total molecular energy, −52.753 a.u., is 0.468 a.u. higher than the experimental value. A value of 12.9 eV is obtained for the ionization potential, which is to be compared with experimental results ranging from 11.9 to 12.1 eV. An electron‐population analysis indicates the presence of very small gross atomic charges (qB=−0.088e; qH(bridge)=−0.002e; qH(terminal)=0.045e). The overlap populations are as follows: n ...


Ambidexterity research has repeatedly emphasized the merits of inter-firm collaboration in the conduct of exploitation and exploration. Prior studies address attributes of inter-firm exploitation and exploration but not whether and how both innovation types may originate simultaneously in single project settings. Focusing on cross-industry innovation - existing solutions from one industry are employed to invention processes in another industry setting - we analyze six case studies on their innovation projects. Our findings suggest that individual learning potentials differ for the collaboration partners, acting as a function of the initial knowledge distance, project role and subsequent process architecture. This analysis has significant implications for research on inter-firm ambidexterity by exposing the potential for balanced exploitative and exploratory learning in collaboration processes in contrast to previous findings that promote structural, temporal or contextual separation of both innovation types.


N-channel Metal Oxide Field-Effect Transistors (nMOSFETs) degrade following a power-law in time: tn where n<1 typically. This ideal degradation curve can be distorted in devices that have been subject to certain types of pre-stress. Such distortion can cause erroneous lifetime extrapolations, unless accounted for in analysis. This paper describes various types of pre-stress and their effect on hot-carrier degradation of L=0.5 μm nMOSFETs designed for 5 V operation. We show how taking into account pre-stress is critical for proper analysis and interpretation of degradation behavior used to guide robust device design.


The penetration of mobile telephony exceeded 100% in only two countries in 2002, and with penetration of 108% Taiwan was the higher of the two. This study identifies the impetuses behind the accelerated growth of mobile telephony in Taiwan, in terms of the diffusion model and forces driving the diffusion. Model comparison methodology is introduced to identify the most appropriate diffusion model. The driving forces for the diffusion rate of the model are then estimated. Empirical results, based on data for 1988-2007, indicate that the Logistic model performs best. Network externalities explain the dynamics and superiority of the Logistic model. Deregulation results in market competition, making it the primary driver for the diffusion. This empirical study also demonstrates that deregulation promotes the diffusion to the takeoff point, which is critical to a self-sustaining diffusion. Overall, network externalities are in conjunction with the deregulation to push the rapid diffusion in Taiwan.


A menu-driven graphics-based simulation package called DESIGN has been developed. It enables the users to add/delete poles or zeros and vary design requirements such as the value of the gain, damping factor, overshoot, delay time, rise time, bandwidth, resonance frequency, etc., to see the effects on system response. The package is designed around the root locus plot of a unity feedback control system in a window environment. It is a useful tool for both the teachers and the students in a basic control system theory course with a special emphasis on design.

The two papers on fetal lung volume published in this issue of the journal highlight the intensified interest in measuring fetal lung volume following the introduction of three-dimensional (3D) ultrasound techniques. The reason for this is clear. The incidence being 1.1 per 1000 live births with a mortality rate of over 50%1, fetal lung hypoplasia poses a major diagnostic challenge. It is reasonable to assume that measurement of lung volume will signify a major step forward in the detection of fetal lung hypoplasia. But will it provide us with the complete picture? The crucial question to be addressed is whether we are dealing with a lethal or non-lethal form of fetal lung hypoplasia in a given case. For this purpose a positive predictive value (PPV) of 100% is needed. Fetal lung size was initially estimated from twodimensional (2D) ultrasound images. Measurements include lung area, lung circumference and lung length/diameter2–13. Lung length has been established in a plane through the long axis of the thorax from the superior end of the sternum to the level of the diaphragm or the inferior surface of the heart9 or from the apex to the base of the lung11. Others studied the ratio of lung area to head circumference (LHR)14–16, lung length to thoracic circumference12 and lung length × width to head circumference17, particularly relative to congenital diaphragmatic hernia. From the data reported so far, it appears that none of these biometric parameters is reliable enough to be applied in clinical management. In a recent study18, it was pointed out that the most reproducible method of measuring fetal lung area was by manual tracing of the limits of the lungs. Multiplication of the longest lung diameter by the longest perpendicular diameter turned out to be the least reliable method18. Also the biometric ratios fail to provide an acceptable prenatal prediction of lethal lung hypoplasia. Moreover, LHR increases exponentially with gestational age18, which is in contrast to the initial assumption that calculation of the LHR would minimize the effects of gestational age on lung size. In another recent study19 it was assumed that the lung represents a geometrical pyramid. An equation was produced (surface area of right + left lung base [cm2] × 1/3 height of right lung [cm]), allowing 3D volume (mL) to be calculated from 2D measurements. It was proposed that this approach could serve as an alternative to 3D ultrasonography and magnetic resonance imaging (MRI). Data on sensitivity and specificity of this method in determining lung hypoplasia are not yet available. Moreover, lung hypoplasia is mostly associated with severe oligohydramnios or anhydramnios, which may alter the pyramidal shape of the lungs owing to outside compression of the thorax. So, will 3D ultrasonography provide us with the ultimate solution? The introduction of 3D ultrasonography would allow for the assessment and correction of surface irregularities20. The more conventional 3D sonographic approach involves scrolling through one plane of the multiplanar display while delineating the lungs in a different plane. Alternatively, the VOCAL technique (Virtual Organ Computer-aided Analysis, General Electric Medical Systems) allows volume calculation around a fixed axis through a number of sequential steps21. Contradictory reports have appeared on the reliability and reproducibility of both techniques concerning volume measurements. Whereas in an in vitro setting, rotational measurements of volume proved to be superior to the conventional technique20, an in vivo study of fetal lung volume demonstrated that the rotational method with VOCAL was less reproducible than the common multiplanar technique21. On the other hand, Moeglin et al.19 found no statistically significant difference between lung volume values obtained using the two 3D ultrasound modes. Not only different 3D sonographic techniques, but also different methods for measuring fetal lung volume have been reported. Mainly in earlier work, fetal lung volume was obtained by subtracting fetal heart volume from thoracic volume19,22,23. The disadvantage of this approach is the inclusion of mediastinal structures (thymus, trachea, esophagus and great vessels) in the measurement of lung volume19. The lack of reproducibility of this indirect measurement limited its introduction into clinical practice. Accuracy may be improved by direct determination of fetal lung volume, including separate measurement of the left and right lungs21,24–28. Ruano et al.26 found that direct 3D sonographic estimates of fetal right and left lung volume using a rotational multiplanar technique were highly accurate when compared with postmortem measurements of lung volume achieved by water displacement. In the two studies of fetal lung volume in this issue, one used the VOCAL technique28, while the other used a Technos MX (Esaote) ultrasound machine and a freehand scanning technique with a position sensor attached to the transducer27. As pointed out by Peralta et al.28, the advantage of the VOCAL technique is that the lower parts of the lung that extend below the dome of the diaphragm can be included and the contour of the lung in each plane can be modified to ensure a more accurate lung volume measurement.


The development of politics as a discipline . . . is not so well advanced that one can say with strong assurance that there is general agreement upon either the basic concepts of the subject or upon the methodology according to which they should be manipulated and employed. Until the arrival of a systematic theory which relates to each other the current miscellany of metaphysics, ethics, juristic systems, institutional descriptions, and small-group experimentation, the student of political behavior may be permitted to explore the material that interests him. . . .


The NbTi superconducting strands and cables for the field winding of 200MW class high energy density type superconducting generator are developed. They are composed of Cu/Cu-10wt%Ni/Nb-46.5wt%Ti superconducting strands and the 10kA (at 5T) class 9-strand compacted cables. The diameter of strands is 1.33mm, and the 9-strand compacted cables are 2.4mm thick and 6.0mm wide. In order to produce high current density NbTi strands, we made strands under the controlled aging heat treatments, the total and final strains, and the strains between heat treatments, by using large scale extruder. Moreover, in order to produce high stability and low A. C. loss NbTi strands and cables, the matrix ratio of strands and the cross sections of strands are optimized. The current density of NbTi filaments for the 4 times aging manufactured 1.33mm dia. strands was Jc = 3150A/mm2 at 5T, 1150A/mm2 at 8T. The critical current of the class 9-strand compacted cable is 10.7kA at 5T. The A. C. losses of the final compacted cables are less than 100kW/m3 at 5T, 5T/s, they are decreased to less than half of the target of the A. C. loss value ( 2) increased about 40% at the operation mode current of the superconducting generator.


In order to improve the quality of the sheared surface in cutting of inner structure bonded sheet metal the cut-off operation is mainly investigated, which is the typical shearing process in sheet metal forming technology. The sandwich sheet metals considered have inner structure which is constructed in the form of crimped expanded metal and woven metal. The inner structure is bonded between solid sheet by resistance welding or adhesive bonding. The shearing process is visualized by the computer vision system installed in front of the cut-off die and the sheared surface is measured and quantitatively compared with the help of the optical microscope after cut-off operation. From test results we found that the influence of sheared position can be observed and explained clearly and this result can be utilized to get the better sheared surface.


Canada is the second-largest country in the world, covering 10 million square kilometres. Our population density is sparse by international standards. Canada is one of the most urbanized nations in the world, however, with one third of the population living in Montreal, Toronto, and Vancouver and 90% living within several hundred kilometres of the American border.1

Approximately 20% of Canadians live in communities of less than 10 000 people. Providing equitable and sustainable health care services to rural Canada is challenging; our extreme weather conditions and diverse geography prove obstacles to traveling over the vast distances and difficult terrain between our scattered communities. For small remote communities, it is hard to provide required technology and adequate numbers of health professionals. This dilemma is shared by all regions in Canada and by most countries around the world. Rural communities suffer from a chronic shortage of family physicians who are challenged to provide primary and secondary medical care to patients who are older, poorer, less healthy, less well educated, and more likely to be obese and to smoke than Canadian patients in urban areas.2-4

This research is focused on the test of the traditional handbrake parking brake vs the electronic parking brake (EPB) systems at Ministry of transport facilities. Different results are obtained when testing on three different roller bed testers from the Maha brand. Data variation results when braking with both systems are the same due to the MOT brake tester characteristics.


Patients with recurrent or habitual miscarriage are understandably anxious for any worthwhile treatment, and progesterone or its analogues have been and are still widely used but there are a number of unresolved problems. (1) What is the actual risk of another miscarriage if no treatment is offered? (2) What proportion of patients can be shown to have a hormone deficiency either in the corpus luteum or the placenta? (3) If there is evidence of hormone deficiency, is that the cause or the consequence of the miscarriage and does specific treatment have any effect? (4) Does psychological support prevent some patients from miscarrying again? The calculated risk of another miscarriage after three miscarriages has been put as high as 73% or even 84% (Malpas 1938; Eastman 1946). The observed frequency is over 50% (MacNaughton 1964; Parazzini 1988) but with any of a wide variety of different lines of treatment the miscarriage rate falls to 20% (Swyer & Daley 1953; Tupper & Weil 1962; Graves 1987). Among women with recurrent miscarriage selectcd for endocrine problems, Jones (1976) showed that the corpus luteum was defective in progesterone production between pregnancies in 35%, as judged by endometrial biopsy. More recently Daya et al. (1988) reported luteal phase defects in 40% of women with recurrent miscarriage who were assessed by endometrial biopsy and serum progesterone. Logically, if it is to be effective, treatment with progesterone in such patients should be started before implantation. In early pregnancy removal of the corpus luteum before the end o f the seventh week of amenorrhoea leads to miscarriage which can be prevented by progesterone therapy but not by oestrogen (Csapo et al. 1972, 1973). On that evidencc 11 rogesterone is indispensable for the maintenan . e of early pregnancy. Further interest has been added to the argument aboirt the clinical significance of progesterone deficiency in miscarriage with the discovery that mefipristone, an antiprogestercne, can effectively terminate early pregnancy up to 41 days of amenorrhoea (Baulieu 19x8). Medical termination with mefipristo .ie and prostaglandin (gerneprost) up to 56 days amenorrhoea is already an acceptable procedurc (Urquhart & Templeton 19x8). Betwee'i 10 and 25% of normal pregnant paticnts sliow some evidence of hormone deficiency dui ing the first or second trimester. and that figurr rises to 70% in patients with previous recurrent miscarriage (Macdonald et al. 1972). However in a series of 74 women with recurrent miscarrial;e, Klopper & MacNaughton (1965) found thri t up to 10 weeks gestation there was no differenc in the pregnanediol excretion curves between the women who later miscarried and those who had a successful pregnancy, and the early pregnanediol output could not be used as an indic;ition for therapy in any one woman. Indeed ocstriol excretion was a better indicator, being lower in patients who did eventually miscarry. Tl,eir conclusion was that the reduction in hormonc, production was the effect rather than the causc of the miscarriage and that at the time of redured pregnanediol excretion the pregnancy W:LS already bcyond salvage. The best randomized trials (Shearman & Garrett 1963; Goldzie ier 1964; Klopper & MacNaughton 1965; R1:ijnders et al. 1988) have all shown hormone treatment to be no more effective than a placebo and they have in the end advised against active t ierapy. If individual randomized controlled trials contain an insufficient number of patients for the result ttJ be statistically significant, a rneta-analy-


This paper details the results of an investigation into a method of moulding samples of nil slump concrete using standard test cylinders. The tests were carried out on samples of ready mixed concrete supplied for use in extrusion kerb laying machines. The method of compaction varied from hand rodding using the standard 16mm diameter rod, to the use of a drop type soil compaction hammer and finally a 35mm diameter blunt ended tamping rod. It was found that the 35mm diameter rod used in conjunction with a 3 layer, 20 blows per layer moulding technique resulted in test cylinder properties compatible with those of the in-situ kerb.


Fluid flow around Manganese nodule mining device in Deep-sea is experimentally investigated using a scale model. The size of miniaturized device is 1/40 times smaller, and similarity principle is employed to analyze the flow characteristics. The model is made by 3D printing method called for MJP(Multi Jetting Printing, Polyjet), and flow velocity distribution is measured. Complicated flow field occurs from the rear of the mining device, and the velocity variation rate decreases with downstream distance in flow direction. Comparative analysis for various operating conditions with the behavior of Manganese nodules is necessary afterward.


Aflatoxin B1 (AFB1) is a widely spread mycotoxin contaminates food and feed, causing severe oxidative stress damages and immunotoxicity. Grape seed proanthocyanidin (GSPE), a natural antioxidant with wide range of pharmacological and medicinal properties. The goal of the present study was to investigate the protective effects of GSPE against AFB1-induced immunotoxicity and oxidative stress via NF-κB and Nrf2 signaling pathways in broiler chickens. For the experiment, 240 one-day old Cobb chicks were allocated into four dietary treatment groups of six replicates (10 birds per replicate): 1. Basal diet (control); 2. Basal diet + AFB1 1mg/kg contaminated corn (AFB1); 3. Basal diet + GSPE 250 mg/kg (GSPE); 4. Basal diet + AFB1 1 mg/kg + GSPE 250 mg/kg (AFB1 + GSPE). The results showed that GSPE significantly decreased serum inflammatory cytokines TNF-α, IFN-γ, IL-1β, IL-10, and IL-6 induced by AFB1. Similarly, GSPE + AFB1 treated group revealed a significant decrease in mRNA expressions of pro-inflammatory cytokines (TNF-α, IFN-γ, IL-1β, and IL-6) in the splenic tissue compared to the AFB1 treatment group. In addition, western blotting results manifested that GSPE treatment normalized the phosphorylation of nuclear factor kappa B (p65) and the degradation of IκBα protein induced by AFB1. Furthermore, GSPE enhanced the antioxidant defense system through activating the nuclear factor-erythroid-2-related factor (Nrf2) signaling pathway. The mRNA and protein expression level of Nrf2 and its down streaming associated genes were noted up-regulated by the addition of GSPE, and down-regulated in the AFB1 group. Taken together, GSPE alleviates AFB1-induced immunotoxicity and oxidative damage by inhibiting the NF-κB and activating the Nrf2 signaling pathways in broiler chickens. Conclusively, our results suggest that GSPE could be considered as a potential natural agent for the prevention of AFB1-induced immunotoxicity and oxidative damage.

Cutaneous leishmaniasis is one of the endemic and neglected diseases known to exist in Ethiopian highlands. However, a neglected tropical disease overshadowed by lack of effective anti-leishmaniasis agent in Ethiopia. Thus, high number of population is faced for various degree of socio-economical and psychosocial morbidity. Hence, this study was initiated and conducted from July-February, 2017/18 to assess the patterns and effectiveness of different types of anti-leishmaniasis agents in Boru Meda Hospital, Dessie District.


This paper derives sufficient conditions for the asymptotic stability of those 2D switching systems than can be represented by Roesser models in a discrete grid. Preliminary results are based on using common Lyapunov functions, giving LMI conditions for stability. To reduce the conservativeness of this preliminary approach, it is proposed in this paper to use a multiple Lyapunov function, which also gives LMI conditions. Two examples are provided to illustrate the results.


In gas insulated switchgear (GIS) substation, due to the operation of disconnect switch and circuit breaker, as well as short-circuit fault, SF6 will break down very rapidly. The superposition of refraction and reflection of high-frequency travelling waves will cause the very fast transient electromagnetic pulse (EMP). High-frequency EMP propagating along GIS core wire will couple to GIS enclosure which forms transient enclosure voltage (TEV). Through the study of new GIS enclosure coupling model which can be verified by site test and frequency effect on the enclosure coupling under high-frequency EMP, results indicate the generation of TEV is closely related to GIS structures and the electromagnetic wave propagation characteristics on its core wire and enclosure. Electromagnetic coupling model must consider the entire propagating and coupling process of EMP in GIS. Paper also shows that TEV is mainly formed by high frequency >0.1 MHz EMP coupling and the difference on coupling extent when frequency is >1 MHz is small.


The anomalous electrical response at low frequencies previously observed in pure ionic crystals has been studied in ionic crystals containing foreign ions. Measurements of the dielectric loss at one kc as a function of temperature have been made on four salts with a variety of foreign ions at several concentrations. A number of loss maxima were observed which depended in height on the concentration of the foreign ion and the heat treatment of the crystal; and, in their position on the temperature scale on the nature of the salt and foreign ion. An interpretation of the results in terms of defect pairs of various types is presented.


It is a great pleasure to be speaking to a business audience here in Reading, in the heart of the Thames Valley. This is an extremely successful economic region – with the highest GDP per head in the United Kingdom outside central London and the 14th most prosperous region in the whole of the European Union. This track record of economic success reflects a concentration of high-tech and knowledge-based industries, particularly in the information and communications technologies sector. The Thames Valley economy also benefits from good transport links to London, other parts of the UK and international connections via Heathrow Airport, which is still Europe's biggest aviation hub in terms of passenger numbers. It is not surprising, therefore, that a number of recent reports have highlighted the growth potential of this region in the current recovery. According to the Work Foundation, the Reading and Bracknell area is assessed to have the best job growth potential of any UK urban conurbation and Swindon and Oxford also make the top 10 in their league table.

Abstract— The relative reactivity of singlet molecular oxygen, 02(1Δg), α‐,β‐,Γ‐and δ with ‐tocopherol (vitamin E) was investigated using microwave discharge generation as a uniquely clean source of singlet oxygen and using a hydrocarbon solvent to approximate the membrane environment. The relative efficiencies of the tocopherols for O2(1Δg) were found to decrease in the order: D‐α‐tocopherol > D‐β‐tocopheroI > D–Γ‐tocopherol > D‐δ‐tocopherol. The reaction products in all cases were found to be mixtures of quinone and quinone epoxides apparently resulting from decomposition of the primary product, the hydroperoxydienone.


Local binary pattern (LBP), as one of the most representative texture operators, has attracted much attention in computer vision and pattern recognition. Many LBP variants were developed in the literature. However, most of them were designed for gray images and their performance remains to be improved for color images. In this paper, we propose a novel color image descriptor named Holistic and Hierarchical Order-Encoding Patterns (H2OEP) for texture classification. In H2OEP, the holistic order-encoding pattern compactly encodes color order variation tendencies for each pixel in color space. The hierarchical order-encoding pattern leverages min ordering, median ordering and max ordering to encode local neighboring relationships across different color channels. Finally, the generated order-encoding patterns are aggregated via central pixel encoding to build 3D joint histograms for image representation. Experiments on four benchmark texture databases demonstrate the effectiveness of the proposed descriptor for color texture classification.


This article reports on a large-scale peer-review assessment of the research done in English departments at German universities, organized by the Wissenschaftsrat. The main aim is to take a critical look at the methodology of the research rating based on a detailed statistical analysis of the 4110 ratings provided by the 19 reviewers. The focus is on the reliability of the ratings and on the nature of the criteria that were used to assess the quality of research. The analysis shows that there is little variation across raters, which is an indication of the general reliability of the results. Most criteria highly correlate with each other, and only the criterion of 'Transfer to non-academic addressees' does not correlate very strongly with other indicators of research quality. The amount of external funding turns out not to be a good indicator of research quality.


The some quantity of solid particles is always presented in gas media. At laboratory conditions in contrast to real combustion it is possible to reduce or to control amount and size of the particles in the test volume. For real applications it's necessary to take into account that reactive gas mixture contains solid combustible particles. In several cases effect of the particles presence can become significant. For example, appearance of responsive particles in the chamber of HCCI can localize ignition process and therefore disrupt concept of homogeneous reaction. The other example is a safety of coal mining industry, when combustible dusts and gases are mixed with air and explosion of hybrid mixture can occur. Several studies [1, 2] showed that the hybrid mixtures are more easily ignited than either one component along. Therefore the investigation of ignition of hybrid gas – dusts – air mixtures remains to be important direction for development of new combustion devices as well as for evaluation the hazard of complex explosions in industry. In our rapid compression machine studies of auto-ignition of premixed gaseous fuel air mixture we found that at temperatures about 1000 K non-uniform ignition is caused by the presence of ultrafine particles [3]. These particles can penetrate into the combustion volume together with test mixture or can be produced by friction between piston seals and cylinder wall during compression stroke. At definite conditions contaminated particles can auto-ignite in the heated gas mixture even earlier than reactive gas component. It causes local decrease of ignition delay and therefore significant deviation of experimental data measured in different tests under the same conditions. It means that time and location of the gas mixture ignition can be controlled by addition of reactive particles. To investigate this phenomenon visualization of direct light emission at auto-ignition process of methane-air, coal dust-air and hybrid mixtures have been performed in this study.

Anaerobic sequencing batch reactor has proven more effective than aerobic systems in treating dye-containing wastewaters which usually contain refractory dyes and organic chemicals. In this study, the composition and diversity of bacterial community present in an anaerobic sequencing batch reactor used for treating dye wastewater were determined by both high-through pyrosequencing and screening environmentally derived gene library based on 16S rRNA gene sequences. Our results demonstrated that Bacteroidetes represented the dominant phylum in dye wastewater, while the second and third most abundant phyla were Firmicutes and Proteobacteria. The genus Enterococcus from phylum Firmicutes was the dominant genus in the bacterial community of wastewater, followed by the genus Novispirillum, which was classified into phylum Alphaproteobacteria. The majority of sequences from environmental Alphaproteobacteria specific 16S rRNA gene library were assigned into genus Novispirillum and Rhodobacter, which were in agreement with our pyrosequencing results. The aforementioned two genera represented dominant Alphaproteobacteria community, which may perform important roles in degrading refractory dyes and organic chemicals in the anaerobic sequencing batch reactor. The results demonstrated that a wide variety of bacterial species were identified at the genera level and some potential degraders such asEnterococcus, Lactobacillus, Novispirillum and Rhodobacter were abundant in the reactor, which potentially contributed to the strong dye reduction ability.

 Key words: Dye wastewater, anaerobic sequencing batch reactor, 16S rRNA gene, pyrosequencing, bacterial diversity.


This paper proposes a sociocultural perspective of mobility, of which migration is only one case, with a focus on mobile families. Consistent with mobility studies, sociocultural psychology of the lifecourse proposes to study both the sociocultural conditions of mobility, and the perspective of mobile people. In addition, in this article, we consider interrelated lives in mobility. We discuss the specific case of one family documented as part of a larger research project on repeated geographical mobility, and highlight the specificities of the context, the experiences of each family member, and some of their overlapping spheres of experiences. We thus hope to document the life of such families, but also to provide theoretical directions for the psychological study of mobility.


Communication is a bridge between people which enables them to share facts, ideas, feelings etc. with each other. Speech communication is easier and simpler compared to other types of communication. But speech disorders affect one's ability to communicate. Dysarthria is a neuro-motor disorder, where one losses his/her ability to articulate words normally due to tongue/muscle weakness or stroke etc. It results in distorted speech which is hard to understand. Dysarthria affect more on the articulation of consonants (stops in particular) than on the articulation of vowels. Intelligibility varies greatly depending on the extent of neurological damage. As consonants are important than vowels in measuring the intelligibility, distortions in consonant production of dysarthric speech are studied and modifications are performed. This work aims at correcting devoicing of voiced stop (voiced stops are pronounced as unvoiced stops with the same place of articulation) by detecting important time instants such as glottal onset, glottal offset and burst onset thereby modifying the distortions in dysarthric speech using TMS320C6713 DSK with CC Studio 5.5. After the dysarthric speech has been recorded on the DSK 6713 processor modification is done to improve its intelligibility. Two databases were used in the experiment such as Universal Access (UA) database and Torgo database. Out of 65 bursts expected from UA database and 128 bursts expected from Torgo database, 84.6% and 82.81% bursts were detected correctly within 0.3 s intervals respectively.


The invention provides a 1,4-dihydroxy anthraquinone waste gas recovery process and a system thereof. High-temperature waste gas enters an inlet of a sublimation device and cooled by cooling water in the sublimation device into phthalic anhydride solids to be transferred out of the sublimation device, and the phthalic anhydride solids serve as phthalic anhydride recovered materials. Gas obtained after phthalic anhydride is cooled enters an absorption tower and makes contact with lime milk prepared from quick lime, acidic components in the gas are absorbed, and then the gas reaches the standard and is exhausted. A calcium chloride solution obtained after absorption enters a spray drying tower for spray drying, and the obtained gas enters a cyclone separator, a bag type dust collector and a tail gas fan to be exhausted; solid powder obtained after spray drying and dust removal enters a high-temperature calcining furnace for high-temperature calcining, residual organic matter in the solid powder is decomposed, and then an anhydrous calcium chloride product is obtained. High-temperature gas at the tail of the high-temperature calcining furnace enters the spray drying tower to serve as a heat source of the spray drying tower.


The exfoliation of two-dimensional metal–organic frameworks (2D MOFs) to prepare few-layered MOF nanosheets (MONs) has been of great interest in recent years. In this work, an efficient and environmentally friendly liquid-exfoliation method is developed to produce stable and high-concentration dispersions of few-layered Zn2(bim)4 MONs. Bulk Zn2(bim)4 can be successfully delaminated in ionic liquid and water mixed solvents, where the ionic liquid acts both as solvent and surfactant. The highest exfoliation rate is up to 47% with a [Omim]Cl volume ratio of 50%. In addition, the prepared Zn2(bim)4 MONs can be easily dispersed in an aqueous solution and stabilized for more than 2 weeks. Zn2(bim)4 MONs are used as a fluorescent sensor to detect metal ions in water and exhibit enhanced sensing ability for Fe3+ than bulk MOFs. The highly dispersive nature after delamination and easily accessible active sites on Zn2(bim)4 MON surface are all in favor of its high-performance in sensing.

The utility model belongs to the ventilation and silencing technology and relates to a microfracture plate muffler. A metal shell (1) is internally provided with a cylindrical microfracture plate shell (3), two ends of which are connected with the metal shell as a whole (1) by end plates (13), and a single-layer resonant cavity (2) is formed with the clearance of the metal shell (1); the shell of the cylindrical microfracture plate is internally provided with a single-layer microfracture plate resonant cavity muffler sheet (4) formed by two layers of flat type microfracture plates (11) and a middle partition plate (6); and two single-layer resonant cavities are formed by clearances between the two layers of flat type microfracture plates (11) and the middle partition plate (6). In the utility model, the muffling volume achieves 12dB(A)/m on average, which is improved by 42% compared with the muffling volume of a two-layer micropunch plate muffler; the resistance coefficient is 1.4 on average; the appearance dimension of the muffler with any specification is reduced by 200mm compared with that of the two-layer micropunch plate muffler of the same specification, and the weight is lightened by one third; and the transportation and installation are convenient and the cost is saved.


ncient architectural buildings are of great value for all modern humanity. Over time, under the influence of vibrations, water and other man-made and natural factors, the foundations of such buildings are destroyed, the soil structure changes. Currently, one of the most popular methods of strengthening soils and strengthening foundations is the jet grouting technology. When the liquid grout passes through the porous rock, the suspended particles of the grout form a deposit. In this paper, we study a one-dimensional model of suspension deep bed filtration in a porous medium with different particle capture mechanisms. The considered filtration model consists of the balance equation for the masses of suspended and retained particles and the kinetic equation for deposit growth. In this case, the deposit growth rate is determined by the concentration function of suspended particles, which, in turn, depends on the properties of the suspension and the geometry of the porous medium. The solution to the problem is obtained for linear and non-linear concentration functions. An asymptotic solution of the problem is constructed for both types of functions near the concentration front of suspended and retained particles. It is shown that the asymptotic and numerical solutions are close over a long time interval.

Many applications of imitation learning require the agent to generate the full distribution of behaviour observed in the training data. For example, to evaluate the safety of autonomous vehicles in simulation, accurate and diverse behaviour models of other road users are paramount. Existing methods that improve this distributional realism typically rely on hierarchical policies. These condition the policy on types such as goals or personas that give rise to multi-modal behaviour. However, such methods are often inappropriate for stochastic environments where the agent must also react to external factors: because agent types are inferred from the observed future trajectory during training, these environments require that the contributions of internal and external factors to the agent behaviour are disentangled and only internal factors, i.e., those under the agent's control, are encoded in the type. Encoding future information about external factors leads to inappropriate agent reactions during testing, when the future is unknown and types must be drawn independently from the actual future. We formalize this challenge as distribution shift in the conditional distribution of agent types under environmental stochasticity. We propose Robust Type Conditioning (RTC), which eliminates this shift with adversarial training under randomly sampled types. Experiments on two domains, including the large-scale Waymo Open Motion Dataset, show improved distributional realism while maintaining or improving task performance compared to state-of-the-art baselines.


Laser cutting of sheet like brittle materials, in particular glass and sapphire, is attracting attention for an increasing number of applications for the display industry, micro optics, micro electronics and others. Nonlinear absorption in the bulk of transparent materials enables tailored energy deposition for cleaving even along complex contours. The separation can be induced by transient effects, the separation plane defined by permanent modifications. We demonstrate examples of tuning the energy deposition by controlling the geometry, the density and accumulation of the energy absorbed in the bulk. The influence of pulse duration, pulse groups, repetition rate, feed rate and beam shaping on the absorption, the inscribed modification and the cutting results are presented. This enables developing different processing strategies for cutting applications covering a broad range of materials and requirements.

A method of extracting and purifying CrylAb protein(Bt toxin) from CrylAb transgenic rice was established. Most of the Bt toxin present in the tissue of CrylAb transgenic rice was extracted effectively with a solution of 50 mmoi/LNa2CO3 and NaHCO3. The crude protein containing Bt toxin was obtained after the pretreatment of CrylAb transgenic rice with ultra-filtration, ammonium sulfate precipitation and centrifugation. The dialysed crude protein was futher separated on DEAE Sephadex A-50 columns and Sephadex G-150 columns. The protein bound on DEAE Sephadex A-50 gel was eluted with buffer solution B(10 mmol/L tris-HCI buffer+1.0 mmol/L EDTA, pH=8.0) mixed with 0. 1, 0. 3, 0.5 and 0.8 mol/L NaCI in a discontinuous gradient elution mode. The peak of the Bt toxin eluted from the columns was identified by ELISA and bioassayed with larvae of tobacco hornworms and silkworms. The purity and the bioactivity of the Bt toxin were determined by means of SDS-PAGE and larvicidal assay, respectively. The purity of the Bt toxin obtained by this method is high, and its insecticidal activity is retained after the toxin is purified.


Applying the relevant theories of system economics,the author analyzed the property rights relationship and the corporation administrative structure of Chinese professional sport leagues and pointed out that the property rights relation of Chinese professional sport leagues is confusion,and the corporative property rights attach themselves to the political power.It lacks the independence and cannot smoothly trade with each other.In addition,the corporation administrative structure is irrational,and the rights of clients lack legal guarantee,the phenomena of "the inner control" is very prominent,and the incentive-constraint system is ineffective,and so on.In order to perfect the corporation administrative sturcture of Chinese professional sport leagues,the author also brings out some countermeasures as follows:making the property rights relationship definite and building modern corporate system;introducing the "league System"and perfecting the corporation administrative structure;amplifying the incentive-constraint system and preventing moral hazard of agents;promoting the system creation and perfecting the relevant marketing,etc.


Introduction. Zilber's original trichotomy conjecture proposed an explicit classification of all one-dimensional objects arising in model theory. At one point, classifying the simple groups of finite Morley rank was viewed as a subproblem whose affirmative answer would justify this conjecture. Zilber's conjecture was eventually refuted by Hrushovski [9], and the classification of simple groups of finite Morley rank remains open today. However, these conjectures hold in two significant cases. First, Hrushovski and Zilber prove the full trichotomy conjecture holds under very strong geometric assumptions [10], and this suffices for various diophantine applications. Second, the Even & Mixed Type Theorem [1] shows that simple groups of finite Morley rank containing an infinite elementary abelian 2-subgroup are Chevellay groups over an algebraically closed field of characteristic two. In this paper, we clarify some middle ground between these two results by eliminating involutions from simple groups which are definably embedded in a linear group over an algebraically closed field in a structure of finite Morley rank, and which are not Zariski closed themselves. One may simplify terminology by saying that G is a definably linear group over a field k of finite Morley rank, implicitly using some expansion of the field language, or just a definably linear group of finite Morley rank.


Richard A.Brualdi and J.Quinn Massey introduced the incidence coloring number in [1], and gave its conjecture, i.e. every graph G can be incidently colored with Δ(G)+2 kinds of colors. The main results of the paper are as follows: we not only prove that the Cartesian product of graphs of path and path, path and cycle satisfies the conjecture, but also give their coloring number.


The multimode nature of the steady-state emission of a laser with a homogeneously broadened line is shown to be the direct consequence of the asymptotic character of the threshold conditions: Because of the spontaneous background the total losses in a laser are always slightly greater than the rate of supply of stimulated photons and the equilibrium between the losses and the stimulated emission in the resonator is reached only when the pumping rate becomes infinite. This is illustrated by a calculation of a multimode steady-state emission spectrum of a gallium arsenide injection laser. The dependence of the output power on the input current is also calculated for this laser.


Resorbable 3D macroporous bioactive scaffolds have been produced for tissue engineering applications by foaming sol-gel-derived bioactive glasse s of the 70S30C (70mol% SiO2, 30mol% CaO) composition. The foams exhibit a hierarchical structure with interconnected macropores (10-500 μm in diameter), which provide the potential for tissue ingrowth, and mesopores (2-50nm in diameter) that enhance bioactivity and resorbabilit y. The effect of sintering temperature on the compressive strength of bioactive glass scaffol ds was investigated. Compressive strength generally increased as sintering temperature increas ed to 800°C, due to a decrease in the textural mesopore diameter and a thickening of the macropore walls. The compressive strength of the foams did not increase as sintering temperature increased fr om 800°C to 1000°C, even though the mesoporosity was eliminated. The modal interconnected macropore dia m ter decreased as sintering temperature increased, but remained above 100 μm until the sintering temperature exceeded 800 °C. Sintering the bioactive glass foam at 800 °C was the optimum treatment for the production of a macroporous scaffold for tissue engineering.


Hybrid analog/digital precoding has been widely utilized in millimeter wave multiple-input multiple-output (MIMO) systems to relieve the severe power consumption of gigasample/s mixed-signal devices. With conventional exhaustive beam searching, however, the beams formed by large antenna arrays can lead to a large time overhead at beam training stage. In this paper, we propose a novel multiuser downlink beam training algorithm to estimate the angle of arrival (AoA) and the angle of departure (AoD) between the base station(BS) and the mobile stations (MSs). The proposed algorithm realizes much reduction of beam training overhead and releases more time resources for users' data transmission.

The industrial revolution 4.0 era is a new chapter era in human civilization. In this era, the swift influence of technology and information has brought human civilization to undergo massive changes in all sectors, including in the education sector. Education has been so severely disrupted that the role and teacher, who was originally a supplier of knowledge, face challenges. This article aims to reveal the role and function of teachers in the industrial revolution 4.0 era using critical analytical methods. The results of this study reveal that the role of teachers in the industrial revolution 4.0 era is that teachers must become facilitators, motivators, constructors, problem solvers, translators of creative and innovative learning scenarios. Whereas the teacher's function is as a figure of change and a figure of reform. Teachers are required to master technology and predict the direction of change and strategic steps in the face of the industrial revolution 4.0 era.
