Until May 1982, the use of instrumented penetrators to obtain in situ measurements of marine sediment properties had been limited to maximum depths into the sediment on the order of 10 m. This paper describes the initial field tests of two gun-launched, instrumented, seabed penetrator systems (ISP-1 and ISP-2). These tests have extended the technology of instrumented seabed penetrators by demonstrating the feasibility of obtaining in situ measurements from depths into sediment greater than 30 m. While the primary objective of these tests was to demonstrate feasibility, a secondary objective was to obtain useful information about the gas-bearing sediments in a region of the Gulf of Mexico currently being actively investigated by several organizations. This paper describes the ISP-1 and ISP-2 and discusses the results of the data from these tests. These data produced estimates of the speed and attenuation of sound in the gassy sediments as well as a sediment shear-strength profile that was computed from a penetrator acceleration profile using techniques described by R. M. Beard at Oceans 81. This paper concludes by discussing several new geotechnical instruments that could be developed to exploit the capabilities demonstrated by these tests.


The consistent advancement of innovation has implied information and data being created at a rate, not at all like ever previously, and it's just on the ascent. The world makes an extra 2.5 quintillion bytes of information every year. The demand for individuals talented in investigating, deciphering, and utilising this information is now high and is set to become exponential over the coming years. The total populace is relied upon to arrive at 9.7 billion by 2050 from the current population of 7.8 billion. The Food and Agriculture Organization (FAO) has predicted that the development of farming must be expanded by 70% to provide for the extended interest. Data-driven agriculture choices can be a potent technology to manage the needs of this much high population, as this technology gives higher efficiency, rehearses support-ability, and even assists with giving straightforwardness to purchasers and consumers needing to find out about their food as reported in the studies. The current and future interests will require more data researchers, data engineers, data specialists, and chief data Officers.  This paper tries to examine the need, use, role, and issues faced by data science and data analytics to improve the quality as well as quantity of Agricultural produce thereby leading to an increase in production, a decrease in costs, and overall sustainability.


We have studied a possible evolution process permitting a 'primitive' membrane to evolve towards a membrane structure with an outer wall, similar to that of bacteria. We have investigated whether a polysaccharide bearing hydrophobic phytyl or cholesteryl chains coats giant vesicles made of single‐ or double‐chain lipids. Phytyl‐pullulan 5b was found to bind to the surface of vesicles made of either single‐ or double‐chain lipids. In contrast, cholesteryl‐pullulan 5a only coated the surface of vesicles made of double‐chain lipids. These results indicate that there must be a close match between the size and shape of membrane constituents and the hydrophobic molecules to be inserted. This process could, thus, provide a selection mechanism of lipid‐membrane constituents during the course of biomembrane evolution.


Accurate morphological differentiation of the individual spermatozoa into normal and pathological forms is only possible with the help of the stained smear preparation. For staining it is essential to prepare the smear on the slide in exactly the same way as for a blood picture; the smears are dried in the air for 24 hours and then stained after Mayer/Stiasny's staining method or Papanicolaou's staining method. For this technical procedure 1 hour is necessary. In order to rationalize work and to give a method of rapid differentiation to the practising physician, a new procedure, that is reported here, was developed. This involves the use of stain-covered slides* which are delivered as finished products.


In this paper, passive control and H ∞ state feedback based on non-fragile observer are presented for a class of uncertain, nonlinear and input time-delay systems. Firstly, taking uncertainties, nonlinearities and input time-delay into account, non-fragile observer and controller are designed and the perturbations of controller gain and observer gain are processed. Secondly, for the dynamic disturbances, an appropriate non-fragile state feedback controller based on the observation is selected to prove that the states of closed-loop system can be passive and stabilized with H ∞ performance for continuous time system. Moreover, the problems such as time-delay are handled in virtue of Lyapunov method and linear matrix inequalities (LMIs). Finally, the simulation results demonstrate the validity of the proposed control design method.


An Acidiphilium cryptum strain and two Acidiphilium symbioticum strains exhibited extremely high tolerance to CdSO4, growing at a concentration of 700 mmol l‐1 or more in MGY medium (g l‐1 composition: KCl, 0.1; MgSO4.7H2O, 0.25; (NH4)2SO4, 2.0; K2HPO4, 0.25; glucose, 1.0; yeast extract, 0.1) of pH 3. Fairly high concentrations of ZnSO4 (200 > 125 mmol l‐1), NiSO4 (50 > 20 mmol l‐1) and CuSO4 (25 > 15 mmol l‐1) were also tolerated by these strains. Acidiphilium multivorum grew in the presence of NiSO4 (400 > 350 mmol l‐1), ZnSO4 (50 > 40 mmol l‐1), CdSO4 (40 > 20 mmol l‐1) and CuSO4 (20 > 10 mmol l‐1) while an Acidiphilium strain GS18h tolerated ZnSO4 (100 > 60 mmol l‐1), NiSO4 (50 > 30 mmol l‐1), CuSO4 (30 > 15 mmol l‐1) and CdSO4 (20 > 10 mmol l‐1) in the same medium. Acidiphilium angustum, on the other hand, was found to be metal sensitive—growth inhibition being observed at concentrations of 10 mmol l‐1 ZnSO4, 10 mmol l‐1 CuSO4, 20 mmol l‐1 NiSO4 and 0.2 mmol l‐1 CdSO4 in MGY medium. Acidiphilium organovorum also exhibited tolerance to these metal sulphates in this medium at the levels of 70 > 60 mmol l‐1 for Zn, 20 > 10 mmol l‐1 for Cd and Ni, and 10 > 5 mmol l‐1 for Cu. This strain, interestingly enough, showed a much higher level of tolerance in MAGY medium (g l‐1 composition: KCl, 0.15; MgSO4.7H2O, 3.36; K2HPO4, 0.15; (NH4)2SO4, 0.15; Al2(SO4)3.18H2O, 2.25; CaCl2.2H2O, 0.97; MnSO4.H2O, 0.12; glucose, 1.0; yeast extract, 0.1) of pH 3 than in MGY medium. Replacement of carbon source, however, did not affect the tolerance levels to any great extent.


We live in an era in which the smallest details are very important for any business or company to remain standing. This is due to the fact that with globalization, the information access are given equally to any entity in the world, forcing them to seek the difference in the smallest details, thus achieving a form of loyalty among its customers. One of those details, and perhaps most important of them is the proper care, be it direct contact with the customer or simply an exchange of e-mail. Thinking about it this paper proposes a tool aimed at managers in the area of Information Technology can help measure, monitor and improve the level of service to its analysts. The tool will include functions such as registration of Regional Manager, joined Analyst, as well as consulting the analyst to be evaluated, query all calls assigned to the analyst in question. Thus, the manager will have in hand a tool that assists in controlling the quality and level of service of its staff, with reports and indicators on hand can make observations about errors committed by the Portuguese Professional indicate and assist as lack of information passed to the customer, as well as guide them about possible flaws in analyst-client relationship.

The number of publications about the Caicaras population is growing, which shows that researchers are interested in these natives. This study aimed to survey the flora used by local specialists of the Praia do Sono Caicara community, and recorded how these taxa were used, with the goal of understanding traditional management systems that help to conserve natural ecosystems. Twelve informants were selected and interviewed. The applied grouping analysis, together with the chi-squared test, underlined that the analysed ethnobotanical knowledge showed a heterogeneous distribution in relation to the gender of the interviewee. A total of 190 taxa were cited and were classified into nine usage categories. The Shannon-Wiener index (H') value obtained in this study was the second highest in comparison to other Brazilian coastal communities. This work showed that the local specialists of this Caicara community maintain a wide knowledge of, and affinity to, the plant resources that surround them. This knowledge is not only important, but fundamental to discussions about the application of sustainable use and management strategies for this area of conservation value.


In this paper, a communication system that is not using the communication line but power line is presented. It will be very useful for an information-oriented society with tele-metering and home automation. Conventional system has a difficulty in transmitting information due to decreasing communication voltage. Proposed idea is a special type switching amplifier system which has a low inner resistance and using high efficient ferrite core in a coupling circuit. This new system is proposed to overcome the loss of conductor load and coupling circuit in a PLC system.


This study attempts to identify the client's main priority when delivering green projects. The aim is to compare whether clients' interests are similar when delivering conventional buildings as compared to green buildings. Private clients invest more in green buildings as compared to government and parastatal entities. Private clients prioritize on maximizing a return on investment and they mainly invest in energy-saving buildings that have low life cycle costs. Private clients are perceived to be more knowledgeable about the benefits of green building projects as compared to government and parastatal clients. A shortage of expertise and managerial skill leads to the low adaptation of green buildings in government and parastatal projects. Other factors that seem to prevent the adoption of green buildings are the preparedness of the supply chain within the industry and inappropriate procurement strategies adopted by clients. Keywords—Construction clients, design team, green buildings procurement.

Satellites, which usually have a lot of solid-lubricated parts, are stored on the ground for a long period before they are launched. During this storage period, degradation of solid lubricants induced by an air atmosphere becomes a major issue. But it is not clear how much influence these storage environments, especially humidity and temperature, have on solid lubricants. In this research, we stored typical solid lubricants for prescribed periods at constant humidity and temperature, and evaluated the effects of storage environments on their tribological properties by conducting pin-on-disk friction tests and XPS surface analysis. Noticeable differences resulted from environmental conditions were obtained.

The proportion of dioecious species in the flora of the British Isles has been underestimated in the past, partly because the total number of native species was overestimated and partly because some dioecious species were omitted for various reasons. We estimate that, in a total native angiosperm flora of 1377 species and species-equivalents, 4.3% (59 species) are dioecious, a substantially higher percentage than the previous estimates of 2, 3.1 and 3%. If gymnosperms are included, 4.4% (61 of 1380 species of seed plant) are dioecious. A review of published work shows that few of these dioecious species have been well-studied, and that for some little or no information is available about their sex ratios and reproductive biology.


PURPOSE
The goal of this study was to identify some potential key cognitive and communicative processes underlying narrative discourse ability following traumatic brain injury (TBI). Specifically, this study (a) investigated the contribution of working memory (WM) and inferencing to narrative discourse comprehension and production; (b) tested key assumptions posited by the Structure Building Framework (SBF), a discourse model; and (c) evaluated the potential for inferencing to contribute to discourse ability beyond a shared variance with WM.

METHOD
Twenty-one individuals with TBI completed six tasks yielding seven measures: verbal and nonverbal WM updating (WMU-V and WMU-NV, respectively), predictive inferencing, the Discourse Comprehension Test (DCT), a picture story comprehension (PSC) task, and story retelling (story grammar and story completeness). Regression analyses were performed using WM and inferencing as predictors for narrative performance.

RESULTS
WM measures were significant predictors of DCT performance and approached significance as predictors of PSC. Inferencing approached significance as a unique predictor for the DCT and story completeness. WMU-V and WMU-NV were highly collinear, and neither WM measure predicted discourse outcomes over and above the other's contribution.

CONCLUSIONS
WM was more strongly associated with comprehension processes, whereas inferencing may be associated with both comprehension and production outcomes. Findings were interpreted as supporting SBF assumptions of domain generality of cognitive processes and mechanisms involved in discourse while also challenging assumptions that the same cognitive substrates are marshaled for comprehension and production processes.

Whereas in brick and mortar stores quality and seller reliability can be effectively communicated through a variety of quality cues, in the online world different mechanisms help sellers establish reputation and trust. Among the commonly used mechanisms by infomediaries that screen and rate sellers are customer-feedback reputation mechanisms where buyers provide seller ratings and feedback. The success of such mechanisms and their impact on prices in electronic markets are described and empirically investigated in this work. Specifically, we investigate both theoretically and empirically (1) whether seller ratings affect consumer valuations, particularly in the presence of insurance; (2) whether seller ratings are indicative of future default likelihood; and (3) whether a seller who is terminal (about to go out of business) is more likely to default prior to exiting.


The Human-Computer Interaction (HCI) community has reported a lack of well-established evaluation methods based on human values. Neglecting values in computing systems can result in a system that does not make sense to users, that does not serve stakeholders, and that can trigger undesirable impacts, difficult to predict and reverse, in the context in which it is used. This situation is even more critical for widely used systems, such as Online Social Networks (OSN). This paper presents a value-oriented method for the evaluation of OSN. The method is based on Organizational Semiotics and inspired by the heuristic evaluation. The method was evaluated by representatives from its target audience and results were positive about its ease and usefulness of use, showing potential to contribute to discussions and practices on human values in HCI.


The brain extraction from cerebral T1 weighted MRI volume is an important pre-procedure for neuroimage analysis. To improve the precision of extraction,an automatic brain extraction method based on a graph-cuts model was proposed. The method uses the brain extraction tool( BET) to obtain the region of interest( ROI) and only performs graph-cuts model in the ROI. A velocity factor was added in the graph-cuts model to eliminate the boundary leakage and local convergence. A slice by slice contour initial method was also used to initialize the 3D brain boundary. The method was applied to 18 cerebral MRI volumes provided by the Internet Brain Segmentation Repository( IBSR). In testing,the mean Dice similarity coefficient was 0. 95 and the results obtained by our method were very similar to those produced by manual segmentation and achieved the best results on many of the evaluation metrics( false positives rate 3. 2% and Hausdorff distance 9. 6) for the IBSR data in comparison of our method with existing brain extraction methods including brain extraction tool( BET),brain surface extraction( BSE),watershed algorithm( WAT),hybrid watershed algorithm( HWAT),graph-cuts( GCUT) and robust brain extraction( ROBEX). The experiment showed the proposed method was precise and robust.

The visual cortical serotoninergic system was compared in normal and dark‐reared cats to determine whether visual experience is necessary for its normal development. In vitro receptor binding of [3H]5‐HT indicated an increase in 5‐HT1 receptor number in dark‐reared cats with no change in affinity. This elevation was specific to the visual cortex and no changes were found in the frontal cortex as a result of dark rearing. Autoradiographic histology revealed that in the normal cat visual cortex, 5‐HT1 receptors were present in all cortical layers and were slightly more dense in supragranular and infragranular layers. In dark‐reared cats, there was a marked elevation in receptor density in supragranular and infragranular layers and little change within layer IV.


Model composition is one of the important activities in model driven engineering, because complex systems are built based on several viewpoints. The composition operation is a tedious task, however, traceability not only provides us with the tool to comprehend its effects, but also helps us to better manage the operation itself. This paper suggests a traceability framework for the model composition operation based on aspect oriented modeling and graph transformation. The generated trace models conform to a generic metamodel that allows representing nested trace links. A merge specification case study is presented to illustrate our contribution.


H. P. DOUB and H. C. JONES (Amer. J. Roentgen., August, 1937, p. 297) record a number of cases of mediastinal hernia and describe the mechanism of its production. It occasionally developed during the course of collapse therapy by means of artificial pneumothorax, and was more common in young persons, in whom the mediastinum i3 easily displaced. In most instances the herniation was through a weak spot in the upper anterior mediastinum and extended into the right chest from a left-sided pneumothorax. Hernias were more common when the intrathoracic pressure showed a high positive reading, but they occurred even when the pressure was negative. The most prominent symptoms were dyspnoea and pain, but aspiration of the pneumothorax usually brought prompt relief. Rupture of the hernial sac gives rise to bilateral pneumothorax or hydropneumothorax, and has been known to result in death.


For $\lambda\ge0$, a $C^2$ function $f$ defined on the unit disk ${{\mathbb D}}$ is said to be $\lambda$-analytic if $D_{\bar{z}}f=0$, where $D_{\bar{z}}$ is the (complex) Dunkl operator given by $D_{\bar{z}}f=\partial_{\bar{z}}f-\lambda(f(z)-f(\bar{z}))/(z-\bar{z})$. The aim of the paper is to study several problems on the associated Bergman spaces $A^{p}_{\lambda}({{\mathbb D}})$ and Hardy spaces $H_{\lambda}^p({{\mathbb D}})$ for $p\ge2\lambda/(2\lambda+1)$, such as boundedness of the Bergman projection, growth of functions, density, completeness, and the dual spaces of $A^{p}_{\lambda}({{\mathbb D}})$ and $H_{\lambda}^p({{\mathbb D}})$, and characterization and interpolation of $A^{p}_{\lambda}({{\mathbb D}})$.

Objective To purify Epstein-Barr virus-specific DNase (EBV-DNase) for further establishment of detection of EBV-DNase antibody in nasopharyngeal carcinoma (NPC) sera. Methods The EBV-DNase extract obtained through combined chemical induction was purified with multistage of gradient linear cellulose column chromatography. Results SDS-PAGE showed that the protein bands were gradually decreased to a single one with a molecular weight of 52kD from the crude extract to the terminal purified product. The immunoradiological determination showed that the units per milligram protein (U/mg) were 5.46, 49.19, 134.86, 391.25 and 967.78 respectively. The enzyme activity was enhanced by 177.2 folds. Conclusion Gradient linear cellulose column chromatography can satisfactorily purify EBV-DNase from the crude cellular extract.


We analyze the empirical power and specification of test statistics in case studies designed to detectat the long-run (one-to three-year) abnormal stock returns. It is found that test statistics based on abnormal returns calculation using a reference portfolia, such as a market index, are misspectified,and three reasons are identified for this specification. We correct the three identified sources of misspecification by constructing a reference portfolia to eliminate this problem.


Introduction: Infections due to Hepatitis B and C are important health issues all over the world. Hepatitis B and C prevalence is increasing among pregnant women in developing countries. It is serious problem because of maternal mortality and transmission of virus from mother to child. This study was designed to determine the frequency of Hepatitis B and C among the pregnant women in Sheikh Zayed Hospital, Rahim Yar Khan, Pakistan. Material and method: This descriptive /cross sectional study was carried out at Sheikh Zayed Hospital Rahim Yar Khan, Pakistan. Blood samples were collected from pregnant women aseptically in the Department of Gynecology Sheikh Zayed Hospital Rahim Yar Khan. HBsAg and anti HCV antibodies were detected using ICT and ELISA technique according to standard operating procedure of the kit manual. Results: Out of 110 pregnant women prevalence of HCV and HBV was 8.2% and 13.6% respectively using ELISA technique. While using ICT, 13.6% of blood samples were positive for HBsAg and 9% for anti HCV antibodies. Hepatitis B positive women had history of ear nose piercing (100%), history of visit to non-qualified health care provider (46.6%), visit to Dai (Non-qualified midwives) (33.3%), history of cesarean surgery (26.6%), blood transfusion (20%), dental surgery (13.3%), abortions (13.3%) and dilatation and curettage (6.6%). In case of HCV, positive individuals had history of ear nose piercing (100%), visit to Dai (Non-qualified midwives) (44.4%), cesarean surgery (44.4%), visit to non-qualified health care provider (33.3%), blood transfusion (11.1%), dental surgery (11.1%), dilatation and curettage and abortions (11.1%). Conclusion: There is high prevalence of hepatitis B and C among pregnant women. So screening of pregnant women at mass level should be started to control the disease.


Abstract About 40% of soils used for agriculture in southwestern Australia (SWA) were acutely copper (Cu) deficient when first cleared, and Cu fertilizer needed to be applied to grow the first wheat (Triticum aestivum L.) crop, the major crop in the region. Tissue testing rather than soil testing is used in SWA to indicate when fertilizer Cu needs to be reapplied to wheat crops. In a glasshouse study using six Cu‐deficient soils from SWA, we compared four Cu soil test procedures as possible alternatives to tissue testing to predict Cu deficiency for wheat. Different critical values were obtained for different soils for all four soil test procedures, indicating separate soil test calibrations would be required for the four procedures for different soils in SWA. By contrast, critical tissue test values in plant parts (young leaves and rest of shoots) were unaffected by soil type. Developing soil Cu test calibrations would be time consuming and costly, and tissue testing has resulted in most deficiency being corrected by fertilizer applications, so there are few Cu‐deficient soils in SWA available to develop the soil test calibrations. Therefore, tissue testing using young leaves is likely to remain the most reliable method for diagnosing Cu deficiency for wheat in SWA and determining when reapplication of fertilizer Cu to soil is required.


The quantum oscillator thermodynamic actions are the conjugate intensive parameters for the frequency in any frequency changing process. These oscillator actions fulfill simple Riccati equations. Interesting Darboux transformations of the fundamental Planck and pure vacuum actions are discussed here in some detail. It is shown that the one‐parameter "Darboux‐Transformed‐Thermodynamics" refers to superpositions of boson and fermion excitations of positive and negative absolute temperature, respectively. A Darboux generalization of the fluctuation‐dissipation theorem is also briefly sketched.


In a wide region of incident angles between -60° and +70°, the self-pumped phase conjugate (SPPC) reflectivities (ri) that are greater than 60% have-been obtained in 45°-cut Ce:BaTiO3 crystal at X=5 l4nm. The SPPC buildup time was 3 sec. . A systematic study was undertaken to assess the i with respect to external angle of incidence (0) and the position (x) of the incident beam upon the crystal entrance face. We have been compared the photorefractive performance of this special 45°-cut crystal of Ce:BaTiO3 with the 0°-cut and 45°-cut BaTiO3 as well as the 0°-cut Ce:BaTiO3 crystal. Intentional doping with cerium has an important effect on the efficiency, sensitivity and spectral response of photorefractive effect. The 45°-cut Ce:BaTiO3 is sufficiently improved its photorefractive phase conjugate performance.

To meet the needs of the 21st century student, college instructors have been challenged to transform their classrooms from passive to active, "minds-on" learning environments. This qualitative study examined an active learning approach known as a flipped classroom and sought to explore student perceptions of flipping a teaching methods course required in an agricultural teacher education program. Students offered mixed perceptions about this flipped class. The emergent themes included: (a) positive aspects of online lecture, (b) technological issues, (c) positive aspects of classroom learning activities, (d) negative aspects of classroom learning activities, and (e) student beliefs regarding the flipped classroom approach. Based on the findings from this study, a flipped classroom approach seems to have promise as a model for delivering a teaching methods class. As a result, we suggest other instructors of similar courses attempt a flipped classroom approach to test the model in other contexts.


How do diverse groups of women in Canada define sexual harassment? To answer this question requires incorporating race and citizenship into the analysis of sexual harassment. The authors use data from seven focus groups of Canadian women. The white women with full citizenship rights most easily identify with existing legal understandings of sexual harassment and believe they have the right to report their harassment. For women of color and women without full citizenship rights, issues of racialized sexual harassment emerge as central factors in their harassment experience. Black women with full citizenship rights call into question whether the term sexual harassment captures their experiences. Filipinas working as live-in caregivers on limited visas demonstrate how racism and lack of citizenship changes definitions of sexual harassment. Their experiences of harassment combine elements of isolation due to their lack of citizenship, racialized sexual harassment, and abuse. The authors argue that intersectional analyses are needed to understand women's harassment experiences and their ability to complain and seek legal recourse.


Under the Industry 4.0 framework, a plethora of digital technologies and techniques has been introduced in the Manufacturing domain. Machine tools must become more intelligent, in order to create a network of fully connected machines. By extension, this will lead to the creation of the Industrial Internet of Things (IIoT). Although these technologies provide for increased functionality of the manufacturing equipment, there are certain issues/implications, refraining engineers from integrating such technologies in the production. Therefore, in this paper, the results of a systematic literature review are presented and discussed, including the horizontal and vertical integration of such digital technologies. The contribution of this paper extends to the recognition of the opportunities emerging as well as the identified implications from a practical implementation point of view.


An ionic liquid containing a random-structured oligosilsesquioxane (Im-Random-SQ-IL) was successfully prepared by the hydrolytic condensation of 1-methyl-3-[3-(triethoxysilyl)propyl]imidazolium chloride (MTICl) in aqueous bis(trifluoromethanesulfonyl)imide (TFSI). Im-Random-SQ-IL exhibited a glass transition temperature (Tg) at −25 °C as indicated by an endothermic peak in the differential scanning calorimetry (DSC) curve. In addition, fluidity was visually observed at ca. 0 °C, i.e. Im-Random-SQ-IL is a room temperature ionic liquid. Conversely, when the hydrolytic condensation of MTICl was performed using a water/methanol (1:19 v/v) solution of TFSI, an ionic liquid containing a cage-like oligosilsesquioxane (Im-Cage-SQ-IL) was obtained. The Tg of Im-Cage-SQ-IL was −22 °C, and its melting temperature (Tm) was 105 °C according to the DSC analysis. In addition, fluidity was observed for this ionic liquid at ca. 100 °C. These results suggest that both the amorphous structure of Im-Random-SQ-IL and the type of substituent groups in the silsesquioxane contributed to the ionic liquid behaviour below room temperature. In addition, these ionic liquids exhibited high thermal stabilities (Im-Random-SQ-IL: Td3 = 429 °C, Td5 = 437 °C and Td10 = 447 °C, Im-Cage-SQ-IL: Td3 = 427 °C, Td5 = 436 °C and Td10 = 446 °C) and relatively high ion conductivities (10−4–10−3 S cm−1, at ∼100 °C).


Rheumatoid arthritis (RA) is characterised by the presence of autoantibodies to 'citrullinated' proteins, the citrullination of which is mediated by peptidylarginine deiminase (PAD). Among these enzymes, two PAD isotypes – PAD 2 and 4 – play a major role in RA pathogenesis. In RA, joints are infiltrated with inflammatory cells, mainly monocyte/macrophages and lymphocytes, and T cell contact-mediated activation of monocytes is known to result in secretion of …

AbstractLabel claims equivalent to "Store below 30°C" in all countries of the globe are often the goal of pharmaceutical companies. It is also in the patients' interest that, wherever possible, the longest expiration date which can be fully justified for the environment in which the product is used, is allocated. In some countries this requires assessment of data generated by continuous storage at 30°C. In other countries the claim can be based on continuous storage at 25°C. For most products where such a label claim is likely, there is usually little, if any, difference between data generated at 25°C and 30°C at early timepoints. At later timepoints significant differences may emerge which allow different shelf-lives to be allocated.This paper describes a technique which allows both claims to be supported statistically without the need to perform parallel testing at both 25°C and 30°C at early timepoints.

Magnetically actuated microswimmers have attracted researchers to investigate their swimming characteristics and controlled actuation. Although plenty of studies on actuating helical microswimmers have been carried out, robust closed-loop controls should be still explored for practical applications. In this paper, we proposed a data-driven model-free method using Image-Based Visual Servoing (IBVS), which uses features directly extracted in the image space as feedbacks. The IBVS method can eliminate camera calibration errors. We have demonstrated with experiments that the proposed IBVS method can enable velocity-independent path following of an arbitrarily given path on the plane, which permits a better experience of user interaction. The proposed control method is successfully applied to obstacle avoidance tasks and has the potential for the application in complex circumstances. This approach is promising for biomedical applications. Note to Practitioners—This paper is motivated by the problem of driving a small-scale swimming robot with a helical body by magnetic fields along a predefined path. The proposed new closed-loop control uses features directly extracted in the image space as feedbacks. We demonstrated with experiments that the helical swimming robot can follow an arbitrarily given path on the plane using the proposed control method. The proposed control method is also successfully applied to obstacle avoidance tasks.

In this study, a potentiometric sensor based on a molecularly imprinted polymer (MIP) was developed for determination of tramadol. At optimized condition the electrode exhibited a Nernestian response (30.5±1.0 mV/decade) in a concentration range of (1×10 -6 to 1×10 -2 M). The potential response of the electrode was constant in the pH range of 1.0-9.0. The electrode demonstrated a response time about 15s. Selectivity coefficient of the sensor with structural similarity to tramadol was evaluated by matched potential method (MPM). The electrode was examined successfully for determination of tramadol in biological fluids and urine with a good accuracy and precision


Abstract : A generalized approach to reverse osmosis process design is presented for solution-membrane-operating systems characterized by the dimensionless parameters gamma, delta, and lamba defined in terms of the pure water permeability constant A, solute transport parameter, mass transfer coefficient k on the high pressure side of the membrane, and the properties of the solution. Analytical expressions are derived, in terms of dimensionless quantities, for the change of volume of solution, concentration of the bulk solution and that of the concentrated boundary solution on the high pressure side of the membrane, the change in the permeating velocity of solvent water through the membrane, solute separation, and the other related quantities, at any instance, as a function of concentration of the product solution on the atmospheric pressure side of the membrane, or time from the start of the operation for reverse osmosis systems specified by gamma, delta, and lamda. The equations are developed first for the case of batch-by-batch operation, and their applicability to the flow case is then indicated. (Author)


This paper reports use of health care services related to health care quality over five years among over 18,000 individuals from a single large employer in the Midwestern United States that adopted an HSA-eligible health plan for all employees. It represents one of the longest observation periods reported with a full-replacement CDHP, and it is one of the few studies with a matched control group. The introduction of the HSA-eligible health plan had a negative impact on office visits for annual physicals, well-child visits, and preventive visits in the year that the plan was adopted. In the second year, office visits increased for HSA-eligible health plan enrollees, but were mostly unchanged for the comparison group. By the fourth year in the HSA-eligible health plan, office visits for annual physicals, well-child visits, and preventive visits were down slightly relative to the comparison group. Rates of LDL testing for adults with cardiovascular disease were reduced only in the first year of the HSA-eligible health plan. However, the introduction of the HSA-eligible health plan had a negative effect on medication monitoring for adults on select maintenance drugs not only in the first year that the new health plan was introduced, but in the following three years as well. The HSA-eligible health plan reduced avoidance of both antibiotics for adults with acute bronchitis and imaging services for adults diagnosed with low back pain. Both services are often considered unnecessary. Adoption of the HSA-eligible health plan was associated with a reduction in breast cancer, cervical cancer, and colorectal cancer screening in year one, although screenings for breast cancer and cervical cancer rebounded in year two. By year four, breast cancer screening was higher among enrollees in the HSA-eligible health plan than in the comparison group. In contrast, cervical cancer screening was lower among HSA-eligible health plan enrollees than the comparison group in year four. Throughout all of the study years, colorectal cancer screening was lower among HSA-eligible health plan enrollees than in the comparison group. The HSA-eligible health plan was not associated with a change in the percentage of adults receiving HbA1c testing until the fourth year. LDL testing was lower as a result of the introduction of the HSA-eligible health plan in all years.


We have developed a method for the detection of clusters of microcalcifications in digital mammograms. Here, we present a genetic algorithm used to optimize the choice of the parameters in the detection scheme. The optimization has allowed the improvement of the performance, the detailed study of the influence of the various parameters on the performance and an accurate investigation of the behavior of the detection method on unknown cases. We reach a sensitivity of 96.2% with 0.7 false positive clusters per image on the Nijmegen database; we are also able to identify the most significant parameters. In addition, we have examined the feasibility of a distributed genetic algorithm implemented on a non-dedicated Cluster Of Workstations. We get very good results both in terms of quality and efficiency.


• Sweden's twin goals – to reduce carbon emissions by 70% in 2030 relative to 2010, and to completely decarbonize by 2045 – present a dilemma: Sweden's diesel truck transportation sector will likely have to choose between meeting near-term goals with biofuels, and pushing more heavily towards electrification options that are essential for long-term climate mitigation goals. • Even though Swedish stakeholders believe that biofuels remain important for Sweden, a shift in sales from internal combustion engines to electrification of trucks will likely start in the coming decade. This means that an analysis of post-2030 biofuel use is needed – and sooner rather than later – to determine how to make this second shift that will unfold among the truck fleet. • Both biofuels and electrification are important for Sweden's freight transport stakeholders; however, a push towards massive biofuel deployment over the coming decade for the 2030 goal would need to be accompanied by an in-depth discussion about how achieve the next needed transition towards electrification. • These insights emerged from SEI analysis of discussions among key stakeholders, who provided up-to-date outlook on key technological measures essential to reduce diesel truck transportation emissions as part of the global effort to limit climate change.


The photorefractive holographic grating in a Mn doped K 1- y Na y Ba 2 -x Sr x Nb 5O 15 (KNSBN) is written with two 0 27mW He Ne laser beams (632 6nm) and is read with one quasicontinuous dye laser beam (621 8nm, 1 6mW or less). It is found that the Bragg diffracton suddenly reaches its maximum at the beginning and then decays to its minimum with a time constant of about 0 6s. The ratio of the maximum to the minimum can be higher than 7 5. A theory including pyroelectric effect has been developed and it fits the experiment well.


Over the last fifteen years, military aircraft Health and Usage Monitoring Systems (HUMS) have morphed from simple data acquisition systems, mostly hardware centric, to more complex softwarerich integrated health management (HM) systems. The latest application to fifth generation military aircraft has propagated the concept of Prognostics and Health Management (PHM). This paper provides a discussion on the attributes, benefits and challenges of novel military aircraft health management systems. Factors affecting successful implementation of prognostics and Knowledge Discovery with aircraft Big Data are further explored.


SAW (Submerged Arc Welding) machines normally consist of two or more torches to increase productivity. The performance of conventional SAW depends on the experience of the operators. Error between the measured and the actual values of welding conditions is accumulated as time goes on. Therefore, the weld quality cannot be guaranteed because of the error. Even if a number of welding defects occur, workers are not able to find out the cause of defects because the measured signals show a big difference with the actual values. In this study, a stable measuring system was developed for the welding conditions such as current, voltage, speed so that workers can easily monitor the actual welding conditions. If the error between monitored and measured signals occurs, workers are able to easily correct the actual welding conditions through this system. In this way, it increased the reliability of the welding conditions. This system was applied to an actual welding system and showed that the weld quality was stabilized and improved.


Recent studies in several neuronal lineages suggest that extrinsic factors such as polypeptide growth factors regulate various stages of neuronal development, from initial commitment of multipotent progenitors to induction of specific gene expression that is characteristic of terminal neuronal differentiation. In the present study, immortalized hypothalamic neurons of the GT1‐1 lineage were used to analyze proliferative, as well as morphological and molecular differentiation actions of basic fibroblast growth factor (bFGF), epidermal growth factor (EGF), transforming growth factor‐α (TGF‐α), and insulin‐like growth factor‐I (IGF‐I). These effects were compared with those induced by specific activators of protein kinase A and C pathways, which potently inhibited cell proliferation and gonadotropin‐releasing hormone (GnRH) gene expression, but stimulated morphological neuronal maturation as determined by the length and number of neurite outgrowth. bFGF exerted a broad spectrum of stimulatory effects, increasing the rate of proliferation measured both by the incorporation of 3H‐thymidine and by cell number, and parameters of terminal differentiation, such as neurite outgrowth and induction of gene expression. bFGF stimulated the expression of the hybrid transgene‐containing portions of the rat GnRH promoter. In contrast, EGF, TGF‐α, and IGF‐I inhibited cell proliferation, while having subtle effects on neurite outgrowth. Thus, GT1‐1 cells appear to be differentially responsive to distinct neurotrophic factors, providing a model for studying the specific effects of neurotrophic factors on functional differentiation, migration, and connectivity of hypothalamic neurons.

In Egypt, reconstituted milk is commonly used for Domiati cheese manufacture, which results in cheese with a cooked flavour. It is suggested that this might be masked and the flavour improved by using some free fatty acids (FFA) (Willart & Sjostrom, 1959). Baltadzhieva (1967) observed that valeric and propionic acids were among the FFA present in cephalotyre cheese and Singh & Tuckey (1968) reported that hydrolysis of fat to a concentration of 10-20 /imol FFA/g cheese solids and presence of isovaleric acid were necessary for typical flavour development of Limburger cheese. The present work was planned to study the effect of the addition of acetic, propionic and valeric acids in masking cooked flavour and improving the flavour quality of Domiati cheese made from reconstituted milk.


Mobile's influence on shopping is growing by leaps and bounds. Rules of retail are changed by mobile-empowered customers. Recent years have seen an increase in number of smartphones but very few people in India use it as a channel for trade. It remains a challenge for retailers to turn mobile traffic into sales. However, if retailers know how to attract Indian buyers via a mobile channel they can develop their marketing strategies to convert potential customers into active ones. Aim of this study is to explore the factors which influence adoption of mobile e-commerce in the retail sector in India and the relationship between these factors. Crosssectional descriptive research design is used for the study. A total of 100 samples were collected. Results of factor analysis reveal that customer service, innovativeness and convenience are the major determinants influencing Indian 1 International Journal of Pure and Applied Mathematics Volume 120 No. 6 2018, 10543-10563 ISSN: 1314-3395 (on-line version) url: http://www.acadpubl.eu/hub/ Special Issue http://www.acadpubl.eu/hub/

For brain function study, it is very important to assess the state of different attention conditions. In this paper, we study a cross-correlation between different attention electroencephalograph (EEG) signals by detrended cross-correlation analysis (DCCA). We use the method to study attention a wave EEG. And, we found that is possible to discriminate the cross-correlation between the meditation state of closing eyes and the absence of mind. It was found that the DCCA values of idle subjects' a wave EEG signals increased compared the meditating participants' a wave EEG signals. And it can be particularly helpful for treatment and brain development research.


Asymmetric Cascaded H-bridge (ACHB) level inverters can output more voltage waveforms with fewer cascaded units while ensuring the quality of output voltage waveforms, so they have attracted more and more attention. Taking the topology of Type-III asymmetric CHB multilevel inverters as the research object, a Modified Hybrid Frequency Pulse Width Modulation (MHF-PWM) strategy is proposed in this paper. This modulation strategy overcomes the local overshoot of low-voltage unit in the presence of traditional Hybrid Frequency Pulse Width Modulation (HF-PWM), thus completely eliminating the low frequency harmonics in the output voltage waveform of Type-III ACHB nine-level inverters, and the Total Harmonic Distortion (THD) of output line voltage of the modulation strategy is lower than that of PS-PWM strategy in the whole modulation degree, which effectively improves the quality waveform of the output line voltage. At the same time, the strategy can also improve the problems of current backflow and energy feedback caused by the high-voltage unit pouring current to the low-voltage unit, thereby reducing the imbalance of the output power of the high-voltage and low-voltage units. Finally, the Matlab/Simulink simulation model and experimental platform are established to verify the validity and practicality of the modulation strategy.


The purpose of this research lies in the development of a user-key dependent removable visible watermarking scheme in JPEG compression domain. The protected images are embedded with the visible watermarks, and further compressed by JPEG compression. The visible watermarks only can be successfully removed by authorized user with the private key. Experimental results show the proposed scheme can recover images to the extent of JPEG-compression qualities.


This paper investigates the ability to determine the boundary of an unknown object scattering waves using three different scenarios. In the first, we assume all far-field data is known from the scattering of a single incident wave. In the second, we assume that there are several nodes that emit waves and receive information back about the scattered wave. In the third, there is only one node which can emit waves with different wavenumbers and measure the scattered wave.


Finding a line plan with corresponding frequencies is an mportant stage of planning a public transport system. A line plan should permit all passengers to travel with an appropriate quality at appropriate costs for the public transport operator. Traditional line planning procedures proceed sequentially: In a first step a traffic assignment allocates passengers to routes in the network, often by means of a shortest path assignment. The resulting traffic loads are used in a second step to determine a cost-optimal line concept. It is well known that travel time of the resulting line concept depends on the traffic assignment. In this paper we investigate the impact of the assignment on the operating costs of the line concept.

We show that the traffic assignment has significant influence on the costs even if all passengers are routed on shortest paths. We formulate an integrated model and analyze the error we can make by using the traditional approach and solve it sequentially. We give bounds on the error in special cases. We furthermore investigate and enhance three heuristics for finding an initial passengers' assignment and compare the resulting line concepts in terms of operating costs and passengers' travel time. It turns out that the costs of a line concept can be reduced significantly if passengers are not necessarily routed on shortest paths and that it is beneficial for the travel time and the costs to include knowledge on the line pool already in the assignment step.


Neuromyelitis optica (NMO) and NMO spectrum disorder are well characterized demyelinating neurological conditions with established but evolving diagnostic criteria. Antibody mediated inflammation underpins their aetiology, in particular relating to antibodies to the aquaporin-4 transmembrane channel. NMO forms an important differential diagnosis to multiple sclerosis, requires a different treatment strategy and is therefore important to discriminate. A middle-aged woman presented with an acute inflammatory encephalopathy with subsequent brainstem relapse. Aquaporin-4 antibodies were positive. Following routine examination, a breast lump, subsequently diagnosed as locally invasive adenocarcinoma of the breast, was diagnosed. This was surgically resected. Initially treatment with methylprednisolone, and a subsequent course of plasma exchange with adjuvant chemotherapy led to an exponential recovery; 18 months later repeat antibody titres were negative and the patient had a residual mild spastic quadraparesis and ataxia. This case complements an evolving data set of paraneoplastic NMO and highlights the need to consider underlying neoplasia when making this diagnosis. Specific treatment of such underlying pathology, alongside appropriate immunosuppressive treatments, remain key therapies in this context and can secure a sustained neurological recovery.


Canonical discrete quantum error correction (DQEC) schemes use projective von Neumann measurements on stabilizers to discretize the error syndromes into a finite set, and fast unitary gates are applied to recover the corrupted information. Quantum error correction (QEC) based on continuous measurement, known as continuous quantum error correction (CQEC), in principle, can be executed faster than DQEC and can also be resource efficient. However, CQEC requires meticulous filtering of noisy continuous measurement data to reliably extract error syndromes on the basis of which errors could be detected. In this paper, we show that by constructing a measurement-based estimator (MBE) of the logical qubit to be protected, which is driven by the noisy continuous measurement currents of the stabilizers, it is possible to accurately track the errors occurring on the physical qubits in real time. We use this MBE to develop a continuous quantum error correction (MBE-CQEC) scheme that can protect the logical qubit to a high degree, surpassing the performance of DQEC, and also allows QEC to be conducted either immediately or in delayed time with instantaneous feedbacks.


This chapter introduces Christian nationalism. It is defined as a conceptual framework—a collection of myths, traditions, symbols, narratives, and value systems—that idealizes and advocates a fusion of Christianity with American civic life. The chapter also introduces the authors' measurement of this concept and compares it to other possible measurement strategies. Finally, the chapter highlights three main arguments for this book. First, it argues that understanding Christian nationalism, its content, and its consequences is essential for understanding much of the polarization in American popular discourse. Second, the authors contend it is not synonymous with, reducible to, or a byproduct of personal religiosity, political views, racism, or authoritarian tendencies, among others. Finally, the claim is put forward that Christian nationalism is not "Christianity" or even "religion" properly speaking. The authors show that Christian nationalism influences Americans' opinions and behaviors in the exact opposite direction that traditional religious commitment does.


Seed coating is a technology to improve germination and homogenize stand establishment. In view of this a field experiment was carried out in 2019 cropping season on farmers and farmers training centers testing sites (FTCs) of Shashamene, Kofale and Arsi Negele of West Arsi zones; to demonstare the effects of seed dressing material '' Genius Coat'' on agronomic, yield and yield components of malt barley. Treatments applied were: (1) Genius coat + Imidam treated seed (2) Imildam only treated seed (standard check). The experiment was laid-out in randomized block design in four replications and replicated over three locations. The plot sizes were 5m x 5m = 25m 2 . Agronomic, pests and yield, data were collected based on the standard procedures. Sample sizes of ten plants/plot were used for agronomic data i.e., for plant height, panicle length, number of productive tiller and seed per panicle. Yield and yield related data; total straw wieght (STW), thousand kernel weight (TKW) and seed yeild (YLD) were collected from the entire plots. Significantly ( p <0.05%) higher plant height, pencil size, spike per pencil and number of productve tiller per plant of (87.46cm, 9.15cm, 32.17 and 8) were recorded from seed treated with Genius coat + Imidam. Similarly, significantly ( P <0.05%) higher thousand kernel weight (48.42g), total biomass (1156.92kg ha 1 ) and grain yield (6.37 t ha 1 ) were obtained from genius coat treated plots as compare to the standard check (seed treated with Imildam). Genius coat + Imidam seed treatement, increased the STW, TKW, YLD by (17, 12 and 26.4)%, respectively over that of the standard check. This yield increment, might associated with nutrient use efficincy of seed coating material and or could be due to the nature of coating substance that can create nitrous environment around germinating seed which might provide nutritional support in early phase of crop development. Unlike biological effects, no significant differences was obseved on disease (scald and net blotch) severity but however, the response of shootfly againest the treatement was showed a significant ( p <0.05) differences in all tested areas. The highest shootfly count (2.56) was recorded for standard check as compared to the genius cout +imildam (0.81). This could be due to the effect of the seed treated chemical imildam with the geinus coat which had a sinergetic effects on the pest, rather than treating imildam lonely. Therefore, genius coat + imidam seed treatment was found to be the best seed treatment material in terms of biological productivity and pest control. Thus, one may recommend for seed treatment in the areas and similar areas of the country where malt barley used as the main crop. However, this study should be repeated to give conclusive recommendation for practical application.


The difficulty of students in carrying out basic techniques on learning material to shot put is the background of this study. There were still many students who have not been correct in carrying out a series of repulsion movements. This study aims to determine the application of the PAKEM (Active, Creative, Effective and Fun Learning) method to improve learning of shot put to students in the 5th grade students of SDN 163/8 Muara Tabir Tebo.The research method used PTK design which was carried out in two cycles. The subjects of this research were 24 students of the 5th grade students of SDN 163/8 Sungai Jernih Muara Tabir, Tebo. The data of shot put results were obtained through performance tests and observation sheets were used to collect data on student activities in following the learning process of shot put using the PAKEM method. The results of this study were obtained based on the assessment of three aspects namely psychomotor, affective, and cognitive. The results of the assessment shown that there was a significant increase from the condition of cycle I to cycle II. The results of the assessment of learning shot put obtained from the first cycle were as many as 15 students or the percentage of completeness 71.3%. Whereas in cycle II there was an increase to 20 students or the percentage of completeness to be 83, 3%. Based on the results of the study, it was concluded that learning shot put through the PAKEM method can improve the learning outcomes of the fifth grade students of SDN 163/8 Sungai Jernih Muara Tabir.


Cancers are a worldwide concern;oral,esophageal and gastrointestinal cancers represent important causes of cancer-related mortality and contribute to a signif icant burden of human health.The DNA repair systems are the genome caretakers,playing a critical role in the initiation and progression of cancers.However,the association between the genomic variations of DNA repair genes and cancer susceptibility is not well understood.This review focuses on the polymorphic genotypes of the non-homologous end-joining DNA repair system,highlighting the role of two genes of this pathway,XRCC5 and XRCC6,in the susceptibility to digestive system cancers and discussing their potential contributions to personalized medicine.


Ambient seismic noise has long been considered as a nuisance for the analysis of seismograms. For some years now, it has shown a great potential for monitoring various geological objects with high accuracy. Here, using ambient seismic noise generated by sea wave impacts, we reconstruct surface waves propagating within a sea dike body, and monitor the tidal response of the structure as the water level changes. Velocity and attenuation variations are obtained respectively from delay and spectral amplitude measurements. We localize lateral areas of variation which temporal evolution is correlated with water level. These variations are interpreted as the consequence of water infiltration inside the structure.
The proposed method may provide a solution for detecting internal erosion, generally only observed at late stage by visual inspection.


Many garden buildings in Australia exhibit Oriental or Oceanian influence (to date over forty known examples). These structures range over a wide chronological period without

Harmonics and grid synchronization are one of the major problems faced when dealing with a single-phase system. The development of technology in the PV system makes the consumer to use it in a wide range. The power transferred from PV to grid needs DC to AC conversion process which is done by static devices operating with the higher frequencies that causes the harmonics in the grid connected system. The main aim of the paper is to implement grid synchronization and reduce total harmonic distortion in a single-phase grid connected system. The design of LCL filter is addressed in this paper which depends on current ripple, filter size and switching ripple attenuation.  In order to account the harmonic content, the FFT analysis is made both in analysis and Matlab Simulink. The Proportional Resonant (PR) controller is developed and work along with LCL filter for reducing the harmonic content. The stability of the system with PR is analyzed using root locus and bode plots and results are compared with PI controls. The result shows that PR controller performs better compared to the PI controller for reducing the harmonic content present in the single-phase system and for improving the system stability.


In this paper we address the problem of video internetworking where a compressed bit stream is transmitted through networks of different capacities. Using a video transcoding architecture previously proposed by the authors, an efficient bit rate control algorithm is devised in order to match the bit rate ratio to a given network bandwidth constraint. By using a dynamic control of the transcoding buffer, different compression ratios are achieved for each type of picture in MPEG-2 coded video. It is shown that transcoded picture quality is almost the same as that obtained by directly encoding the uncompressed video at the same lower rates. The proposed algorithm has low latency and is computationally very simple.


Philodendron is a very beautiful ornamental foliage plant, adding an aesthetic value in the garden and as a indoor plant in the indoors. It is commonly propagated by clonal method However, this is rather a slow process to meet the demand of planting materials. Therefore, the trial was conducted to standardize the protocol for micropropagation of philodendron for rapid multiplication. Nearly 90 per cent establishment was obtained from segments containing axillary buds on MS medium supplemented with BAP and IAA. Proliferation of shoots and shoot elongation were enhanced by lowering the levels of BAP and IAA. Successful establishment and proliferation were also obtained with only BAP as supplement to MS medium. But establishment and proliferation were significantly stimulated by incorporation of IAA along with BAP. In case of rooting of in vitro shoots, it was successfully induced on half MS medium with incorporation of IBA. In vitro plantlets were hardened well in pots filled with mixture of soil, leaf mould, and tera care. Acclimatized plants were grown with cent per cent success under normal conditions.


It is of critical importance to be aware of the historical discrimination embedded in the data and to consider a fairness measure to reduce bias throughout the predictive modeling pipeline. Various notions of fairness have been defined, though choosing an appropriate metric is cumbersome. Trade-offs and impossibility theorems make such selection even more complicated and controversial. In practice, users (perhaps regular data scientists) should understand each of the measures and (if possible) manually explore the combinatorial space of different measures before they can decide which combination is preferred based on the context, the use case, and regulations. To alleviate the burden of selecting fairness notions for consideration, we propose a framework that automatically discovers the correlations and trade-offs between different pairs of measures for a given context. Our framework dramatically reduces the exploration space by finding a small subset of measures that represent others and highlighting the trade-offs between them. This allows users to view unfairness from various perspectives that might otherwise be ignored due to the sheer size of the exploration space. We showcase the validity of the proposal using comprehensive experiments on realworld benchmark data sets.


The content of dissolvable metals(including 7 heavy metals) and their spatial pattern in the Liaohe River,Liaoning were analyzed to estimate the sources of these metals base on principal component analysis(PCA).The results showed that average contents of dissolved heavy metals in the Liaohe River was in the order of AlCuZnCrHgAsPbCd.Compared to some main waterbodies of Euramerican developed countries,the metal pollution in Liaohe River was serious.PCA analysis indicated that the agricultural runoff and industrial wastewater discharge,industrial integrated pollution were the 2 main sources of metal in Liaohe River.According to the score of main component,the metal source of sampling site 3,sampling site 2 and sampling site 7 was agricultural runoff and industrial wastewater discharge,and the metal source of sampling site 4 was industrial integrated pollution.The PCA based metal source estimation had provided the important guiding line for implementation of metal pollution preventive and countermeasures.


Buddhist pagodas have long served centres of book culture and printing in Vietnam, as in other areas of East and Southeast Asia, but the materials printed there have long been excluded in the literature on book history and reading culture. In this paper, we situate the collections of the books from Thang Nghiem and Pho Nhan temples within the history of the local production of religious texts and their proliferation along the inter-regional and international trade routes. In this paper, we describe the book market and reading cultures of Vietnam since the 18th century in order to place the temple collections in a broader context and show the different strands of the print world represented in the temple collections. We raise questions about the relationship between publishers and readers, the differences between for-profit and not-for-profit printing, and the role of manuscripts versus printed texts. 2. Liam KELLEY (University of Hawaii at Manoa) Working Title: The Significance of Insignificant Libraries: The Thắng Nghiêm and Phổ Nhân Temple Libraries as Examples of Late Imperial East Asian Common (Buddhist) Knowledge Abstract: In examining the holdings of the Thắng Nghiêm and Phổ Nhân temple libraries what becomes immediately evident is that there is nothing particularly special about their collections. They do not, for instance, possess rare or unknown works. They are also not very extensive. Nonetheless, the limited number, and eclectic mixture, of texts that they do possess can help us gain a sense of what "Buddhist knowledge" was constructed from at the local level in late imperial Vietnam. In this paper, the author will seek to present an overview of how we can place these small libraries and the Buddhist knowledge that they represent in the larger world of East Asian Buddhism and common knowledge. By demonstrating how "insignificant" these libraries are, the point of this paper will be to also demonstrate how "significant" these libraries are for providing a window onto an ordinary (Buddhist) world in late imperial Vietnam.

EnglishIf historically, heritage digital libraries were initially made up of images, they rapidly benefited from the optical character recognition (OCR) technology to index print collections and improve reference services for users. However, access to iconographic resources has not experienced the same progression, remaining somewhat difficult to access. Manual indexation is not very efficient, it is varied and impossible to apply uniformly. Searching the content of an image is not as effective with heritage collections. Today, it is possible to improve the use of these resources by exploiting large volumes of OCR produced over the past two decades (both the textual descriptors as well as the automatic identification of the illustrations in the printed documents) and to take advantage of proven artificial intelligence techniques, especially deep learning. In doing so, it will showcase engravings, drawings, photographs, maps, etc. as such but also the point of entry to the collections by improving discovery and connections. This article describes an ETL (extract-transform-load) approach as it applies to the images in a digital library with an encyclopedic vocation. There are three components: 1) identify and extract the iconography wherever it is found, either in images or in the printed documents, 2) transform, harmonise and enrich the descriptive metadata with the help of artificial intelligence, and 3) incorporate this data into a web application dedicated to iconographic research. This is a two-pronged approach because it highlights existing digital resources and takes advantage of the benefits of artificial intelligence. francaisSi historiquement, les bibliotheques numeriques patrimoniales furent d'abord alimentees par des images, elles profiterent rapidement de la technologie OCR pour indexer les collections imprimees afin d'ameliorer le service de recherche d'information offert aux utilisateurs. Mais l'acces aux ressources iconographiques n'a pas connu les memes progres et ces dernieres demeurent dans l'ombre : indexation manuelle lacunaire, heterogene et impossible a generaliser ; silos par genre documentaire ; recherche dans le contenu des images encore peu operationnelle sur les collections patrimoniales. Aujourd'hui, il serait pourtant possible de mieux valoriser ces ressources en exploitant les enormes volumes d'OCR produits durant les deux dernieres decennies (tant comme descripteur textuel que pour l'identification automatique des illustrations des imprimes), en profitant de la maturite des techniques d'intelligence artificielle (en particulier l'apprentissage profond ou deep learning), pour mettre ainsi en valeur ces gravures, dessins, photographies, cartes, etc., pour leur valeur propre, mais aussi comme point d'entree dans les collections, en favorisant decouverte et rebond. Cet article decrit une approche ETL (extract-transform-load) appliquee aux images d'une bibliotheque numerique a vocation encyclopedique : identifier et extraire l'iconographie partout ou elle se trouve (dans les collections d'images, mais aussi dans les imprimes) ; transformer, harmoniser et enrichir ses metadonnees descriptives grâce a l'IA ; integrer ces donnees dans une application web dediee a la recherche iconographique. Cette approche est qualifiee de pragmatique a double titre, puisqu'il s'agit de valoriser des ressources numeriques existantes tout en mettant a profit les acquis de l'IA.

To explore the perspectives of stakeholders towards a range of policy options to respond to obesity in Poland, a multi‐criteria mapping method was used. During structured interviews, stakeholders were invited to appraise policy options by reference to criteria of their own choosing. They also provided relative weightings to their criteria, generating overall rankings of the policy options in relation to each other.


This paper,proceeding from the general theories of legal responsibility described by jurisprudence in China,makes an analysis and investigation on the theories absorbed by the department of economic law,and points out its limits and defect.On the basis of this,the author holds that we should renew to describe the legal responsibility of economic law.


Triangular enclosures are typical configurations of attic spaces found in residential as well as industrial pitched-roof buildings. Natural convection in triangular rooftops has received considerable attention over the years, mainly on right-angled and isosceles enclosures. In this paper, a finite volume CFD package is employed to study the laminar air flow and temperature distribution in asymmetric rooftop-shaped triangular enclosures when heated isothermally from the base wall, for aspect ratios (AR) 0.2 ≤ AR ≤ 1.0, and Rayleigh number (Ra) values 8 × 105 ≤ Ra ≤ 5 × 107. The effects of Rayleigh number and pitch angle on the flow structure and temperature distributions within the enclosure are analysed. Results indicate that, at low pitch angle, the heat transfer between the cold inclined and the hot base walls is very high, resulting in a multi-cellular flow structure. As the pitch angle increases, however, the number of cells reduces, and the total heat transfer rate progressively reduces, even if the Rayleigh number, being based on the enclosure height, rapidly increases. Physical reasons for the above effect are inspected.


The author takes a global look at the entire world of R and D, dividing it into the Centre (the large countries of the developed world) and the Periphery (small developed countries and the Third World). Her objective is to help to formulate a programme of studies to make R and D carried out in the Periphery more relevant to its needs.

Her view is that (a) too many past studies of R and D productivity have been carried out by the Centre on the Centre and (b) too much effort has been expended on measuring outputs and too little on the inputs that could be controlled to produce more output. In the paper she looks at the three major clusters of controllable input factors that could influence R and D productivity. The clusters considered are those pertaining to research groups, the 'atoms' of R and D (size, age, composition, management style and task diversity), to the institutional setting (organizational form, institutional goals etc.) and to the general socio-cultural environment of the country concerned. In each case she questions whether their effects on productivity, mainly derived from studies of R and D at the Centre is likely to apply in the same way to R and D carried out at the Periphery.

The author remarks that the factors listed in the paper are not exhaustive and in any case their interrelationships would also need to be discovered. The paper contains a large number of so far unanswered questions about input/ output relations in the context of the periphery that could provide starting points for research.


Natural gas/diesel dual-fuel engine has become an urgent need to alleviate the energy crisis and reduce emissions. As an additive, reforming gas can improve the combustion process of dual-fuel engines because it improves the combustion rate and compensates for the low reactivity of natural gas. Therefore, it is of great significance to study the ignition characteristics of natural gas diesel blends by adding H2 and syngas. Based on ANSYS Chemkin 17.0 software, the ignition delay time was solved by a closed uniform model. The effects of H2 and syngas on the ignition performance of a natural gas/diesel engine were studied. The results showed that the ignition delay time of the methane/n-heptane mixture was prolonged after adding H2 in the range of medium and low temperatures. This was due to the fact that reaction R3 (OH + H2 = H + H2O) was an endothermic reaction, which consumed OH radicals and inhibited the ignition process. In the high-temperature range, adding H2 reduced the ignition delay time of the mixture system, which was because of the significant increase in the sensitivity coefficients of R1(H + O2 = O + OH) and R3 and the generation of OH radicals. Therefore, the reduction in ignition delay caused by H2 addition in the high-temperature regions was mainly attributed to R3 and R1. In syngas, CO reduced the ignition delay time of methane/syngas/n-heptane. However, the addition of CO could reduce the importance of R3 in the reaction process—resulting in the weakening of the influence of H2 on ignition delay. This study can expand the theoretical basis of ignition characteristics of methane/n-heptane mixture with H2 and syngas under dual-fuel engine-relevant conditions.


A newly-developed roll-surface defect detector which was installed at No. 3 tin temper mill (3TMP) at JFE Steel's West Japan Works (Fukuyama District) is introduced. In this system, defect images are detected by an all-purpose charge coupled device (CCD), and an original logic which was developed focusing on the periodic nature of roll defects is applied to judge defects. Although it was impossible to detect extremely small defects with the conventional technology, as such defects were below the noise level, the new system enables detection of these defects by defect recognition using only periodic signals.


Although the first description of the collective wobbling mode was based on even-even nuclei, all examples to date have been observed in odd-A nuclei. In fact the unpaired, highly-aligned i13/2 quasiproton has proven to play a pivotal role for the observation of wobbling in lutetium and tantalum nuclei. As first suggested in Ref. [7], the i13/2 quasiproton drives the nuclear shape toward a larger deformation than the other quasiparticle states located near the Fermi surface. At these larger deformations, a significant gap in the quasineutron energy levels opens at N = 94 and stabilizes an asymmetric shape with γ ≈ 20◦. Following the initial discovery of the first wobbling structure in Lu [8], particle-rotor model calculations were primarily used to describe features of the exotic wobbling mode, see Refs. [9–12]. Random-phase approximation calculations were also able to reproduce experimental results of the wobbling bands, see Refs. [13–16]. In particular, the unusually large transition strength ratios B(E2)out/B(E2)in could be described in both models. However, the previous particle-rotor model phonon description of the wobbling energy has not been able to reproduce a systematic feature of the known wobbling bands. Figure 1 displays the energy splitting between the wobbling band and the πi13/2 sequence upon which the wobbling structure is based. In all four cases where the wobbling energies are known, it is found that the energy splitting reduces with spin. That is, the wobbling band is becoming lower in energy, with respect to the πi13/2 band, as spin increases. As outlined below, with the previous assumptions in the particle-rotor calculations, the wobbling sequence should actually increase in energy with spin. However, we propose a different set of assumptions that can not only reproduce the same large

Article type: Original Article Background: Reports on the association of nosocomial bacterial infections with indwelling medical devices such as intravenous catheters (IVC) has increased in recent years. The potential to form biofilm on these devices seems to be the main reason for establishment of such infections. The aim of this study was to measure the potential of biofilm formation by bacterial isolates from IVCs. Methods: Seventy-one IVCs were collected from hospitalized patients in ICU, NICU, hematology and oncology wards at Taleghani Hospital from Jan 2010 to Jan 2011. The bacterial isolates were identified using the standard biochemical tests and the potential to form biofilms was determined by the microtiter plate assay method (MTP) and colony morphology using Congo red agar plates (CRA). Results: Overall, 54 (71%) IVCs were colonized and 76 bacteria were isolated among which, 64 (84.2%) were coagulase negative staphylococci (CoNS), 3 (3.9%) S. aureus, 3 (3.9%) Enterococcus spp., 2 (2.6%) E. coli and 4 (5.3%) were miscellaneous isolates not further identified. Among the CoNS, biofilm formation was observed in 68.7% and 82.8% of bacteria using MTP and CRA methods, respectively. S. aureus and E. coli isolates also were biofilm producers but Enterococcus and other unknown isolates were biofilm negative. Conclusions: Our results confirm that the prevalent biofilm forming bacteria on IVCs were CoNS and that was the reason for high rates of nosocomial infections. Article history:


This review paper will explain some of the results of research on the development of soundproofing wall technology. It was starting from the single-layer, double-layers, triple-layers soundproofing walls to have a sandwich structure. Sound Transmission Loss (STL) and Sound Absorption Coefficient (SAC) are the two biggest acoustic problems that must be solved in designing soundproofing walls. The selection of the right material and modifications that can be made possible to improve the performance of the soundproofing wall need to be done to overcome this problem, for example, flax fiber material which has a sound reduction efficiency of 21.2% with a thickness of 1 cm. Apart from the choice of sound attenuation, modifications to the soundproofing wall need to be done to improve the performance of the material for example, wooden triple glazed window can reduce sound transmission (STL) by 36 dB. Therefore, research on the type of material that has good acoustic properties and the right type of modification to be used in the soundproofing wall cannot be separated to create an optimal soundproofing wall.

This paper describes a study carried out to determine the factors affecting the visibility of braking lights through fog in daytime and night time conditions. Regression analysis of experimental results led to the following conclusions: (1) the visibility of braking lights through fog is proportional to the logarithm of its luminance defined in terms of attenuation through fog; (2) at night visibility is affected by the halo dimensions which increase with fog density; (3) visibility is independent of difference in visual angle due to observation distance; (4) the higher daytime luminance (10 times) gives the same visibility as at night; and (5) the foregoing findings can be applied to separated and to combined lamps. /TRRL/


Introduction Advancement in tissue engineering provides a promising approach to recover the functionality of the degenerated intervertebral disc. In our study, a nucleus pulposus (NP) cell-seeded collagen II/hyaluronan/chondroitin-6-sulfate (CII/HyA/CS) tri-copolymer construct was implanted into the disc space directly after nucleotomy in a rabbit model. The aim of this study was to investigate whether the NP cell-seeded CII/HyA/CS tri-copolymer constructs could regenerate the degenerated disc in vivo after implantation into the rabbit nucleotomy model. Materials and Methods NP cells isolated from thoracic and lumbar spines of New Zealand white rabbits of about 3 weeks of age and 1 kg in weight were labeled with a 5- (and-6)-carboxyflurescein diacetate succinimidyl ester (CFDA-SE) fluorescent dye and seeded within the CII/HyA/CS scaffold by a centrifugation method. After in vitro culture for 1 week, NP cell-seeded CII/HyA/CS tri-copolymer constructs were allografted into the disc defects of recipient rabbit immediately after nucleotomy of the lumbar spine. The Bradner disc index and the T2-weighted signal intensity index were determined using lateral plane radiographs and magnetic resonance imaging at 4, 12, and 24 weeks after the operation. Finally, the operated discs were explanted for gross morphological observation, histological evaluation, and cell viability assessment. Animals with only nucleotomy and cell-free CII/HyA/CS scaffold implantation served as controls. Results In our study, we could demonstrate that the T2-weighted signal intensity index of the operated discs decreased in all three groups 1 month after surgery and the index of the cell-containing scaffold insertion group was significantly higher than that of the other two groups. After 24 weeks, the index of the cell-containing scaffold insertion group increased significantly. However, further decline was observed in both the noninsertion group and the scaffold insertion group. In radiographic analysis, the narrowing of the intervertebral disc space was significantly retarded by the cell-scaffold hybrids implantation up to 24 postoperative weeks. Moreover, the gross morphology and histological evaluation indicated that the allografted NP cells were viable and showed extracellular matrix production. Conclusion In our study, we had constructed rabbit NP cell-seeded CII/HyA/CS tri-copolymer implants in vitro. Immediately after nucleotomy of the recipient rabbit, we allografted the precultured cell-scaffold hybrids into the lacuna of the disc. Results documented survival of the allografted NP cells and extracellular matrix deposition, which finally resulted in maintenance of disc height and restoration of T2-weighted signal intensity on magnetic resonance imaging.

In comparison with the pretreatment and determination methods for soil samples,ASE-HPLC method was established to determine the content of 16 polycyclic aromatic hydrocarbons(PAHs),one category of persistent organic pollutants in soil.Both recovery rate and detection limit of the method were observed afterward.The results showed that the recovery rate of naphthalene was around 65%,while the recovery rate of other 15 PAHs ranged between 70%~130%,which are consistent to the US EPA criterion.Taking the trinal excursion of baseline as the absolute limit of detection,the detection limit of the present method is up to 0.5μg/kg.


Introduction: Melanomas are neoplasms that usually develop on the skin with a high prevalence and a mortality rate that is increasing year by year. Studies reflecting the data of this neoplasm, which has a very high mortality rate in our country, are still limited today. Our aim in our study was to retrospectively evaluate the skin melanoma cases treated in our hospital and to compare them with other studies. Material and Method: The clinical and histopathological features of 57 patients diagnosed with skin melanoma in the pathology clinic of our hospital between 2010 and 2019 were examined. Results: The mean age (1956) of patients was 63.18  16.54 years. The lesions were located in the head and neck in 21 patients (36.8%), in the lower extremities in 16 patients (28.1%), in the upper extremities in 11 patients (19.3%) and in the trunk in 9 patients (15.8%). Metastasis developed in 9 (15.8%) patients during a minimum 1-year and maximum 10-year follow-up of our cases. In the present study, 40 patients (70.2%) were diagnosed with nodular melanoma, 8 (14%) with superficial melanoma, 2 (3.5%) with lentigo and 7 (12.3%) with acral melanoma. Discussion and Conclusion: As a result, most of our melanoma cases appeared as nodular type in the head and neck region due to sun exposure. Our study showed that these patients applied to the health institution in the late stage. In melanoma, early diagnosis seriously affects the prognosis.


An infrequent and difficult to treat complication of the neurosurgical removal of a lesion in the frontal or parietal lobes is cortical myoclonus (CM).1,2 CM has also been linked to focal lesions in the same locations independently from their surgical removal.3-5 In the present case and in the majority of the reported cases, the paramedian premotor cortex was involved. However, all except one of the lesions that were previously reported were not adjacent to the primary motor cortex as in our patient (figure, A). Treatment of myoclonus can be difficult and polytherapy is often required for an acceptable result.6 We present a case of CM that started 5 days after surgery, was not responsive to benzodiazepine and levetiracetam, and resolved only after perampanel administration.

Attempts to prepare rhenium hexachloride by the method described by Colton (2) have been unsuccessful. The products of the reaction were always impure rhenium oxotetrachloride and rhenium pentachloride. A compound of rhenium(VI), ReOCl4OPCl3, is shown to have a structure analogous to that of rhenium(V) ions [ReOX4.L]− in which the ligands are in a pseudooctahedral arrangement with L trans to the oxo-group (3). Reactions of ReOCl4 and ReOCl4-OPCl3 with pyridine and 2,2′-dipyridyl are described, and a scheme is proposed for the reactions of the products. Two stable complexes of perrhenyl chloride with the above amines have been obtained.


AbstractThe purpose of this article is to investigate the effect of magnetic nozzle for disk Magnetohydrodynamics (MHD) accelerator using by Q1D (quasi-1-dimentional) numerical simulation. As results, as constant applied magnetic field of 2T is supplied to the MHD channel and 3, 6, 8 and 10T are supplied to the nozzle, acceleration performance for these cases could not observe the significant difference. However as applied magnetic field of 3, 6, 8 and 10T are supplied to downstream side of the MHD channel and the nozzle, gas velocity for case of 6T was accelerated to 3170m/s and 10T was accelerated to 3040m/s. Because of excessive applied magnetic field induced compression due to joule heating and friction loss.
