Objective To observe the renal protection effect of gastric bypass, and explore its possible mechanism in type 2 diabetes mellitus (T2DM) rats. Methods Forty SD rats were randomly divided into normal control group (n=8) and diabetes model group (n=32). Rats in diabetes model group were injected STZ (35 mg/kg). After the diabetes model was reproduced successfully, they were randomly divided into diabetes control group (n=8), diabetes sham-operation group (n=8) and diabetes operation group (n=14). Roux-en-Y gastric bypass was performed in rats of diabetes operation group. The fasting blood glucose (FBG), renal hypertrophy index (kidney weight/body weight), blood urea nitrogen (BUN), serum creatinine (Cr), activity of total superoxide dismutase (TSOD) and glutathione peroxidase (GSH-PX), content of malondialdehyde (MDA), activity of aldose reductase (AR) and AR mRNA expression in the kidney were determined 8 weeks after operation. The renal tissue was examined with light microscopy. Results Compared with normal control group, the renal hypertrophy index, FBG, BUN, Cr, content of MDA, activity of AR and AR mRNA expression in the kidney significantly increased in diabetes control group and diabetes sham-operation group, while the activity of TSOD and GSH-PX decreased (P<0.05). Compared with diabetes control group and diabetes sham operation group, the kidney hypertrophy index, FBG, BUN, Cr, content of MDA, activity of AR and AR mRNA expression in diabetes operation group markedly decreased (P<0.05), while the activity of TSOD and GSH-PX increased (P<0.05). HE staining showed that the renal structure was normal in normal control group. The glomeruli became obviously enlarged, mesangial proliferation was marked, and the mesangial zone expanded in diabetes control group and diabetes sham-operation group. Such renal changes appeared milder in diabetes operation group. Conclusion The gastric bypass could protect the kidney of T2DM rats, which may be ascribed to reduction of oxidative stress and inhibition of AR mRNA expression and polyol pathway in renal tissue.

A dynamic model is presented in this paper for modeling the translation of a flexible body over another flexible body with three load transmission points between them. The three contact points on one of the bodies continuously change as one body translates with respect to the other. No software tools currently exist for simulating the dynamic response of this two-body system. In the present model, six degrees of freedom are allowed between the two bodies and then contacts are modeled using constraints that account for the relative motion. The small, elastic deformation of each body is modeled using the method of assumed modes. Numerical results presented demonstrate the dynamic interactions. The steps needed for implementation in multibody dynamics codes are outlined. The Mobile Transporter-Space Station system is a direct application for the present model. YNAMICS formulations1"3 and software analysis tools such f as TREETOPS4 and DISCOS5 model the relative motion between two bodies in an articulated, flexible multibody system through a hinge that can permit up to six degrees of freedom (DOFs). In such models, the relative translational motion is defined as that occurring between two points, one each fixed in each of the bodies, and the relative rotational motion as that between two reference frames, one each attached at the same two points in the respective bodies. A typical hinge definition is shown in Fig. 1. This definition facilitates the modeling of open-loop, articulated flexible multibody systems such as the Shuttle Remote Manipulator System (SRMS) and typical spacecraft with articulating flexible solar arrays. In the case of closed-loop systems, a cut joint is introduced to render the system open loop, with the joint definition the same as above, and then loop closure constraints are imposed. A consequence of the above definition for a joint connecting two bodies is that the dynamics of a flexible beam translating over two rigid supports, studied by Buffinton and Kane,6 cannot be modeled using the above formulations or software. This is because the points on the flexible beam that are in contact with the two rigid supports continuously change as the beam translates. The translation joint modeling in Refs. 1-5 assumes that the translation occurs along a rigid appendage, although the bodies themselves may be flexible. Although not incorporated into TREETOPS,4 Li and Likins7 extended the approach of Singh et al.4 to include travel along a curved flexible path, with a single point contact between the flexible guide and the body traveling on it. Hwang and Haug8 modeled one- and two-point contacts between two flexible bodies but presented numerical results only for the single-point contact case. Another system that cannot be modeled using the above joint definition alone is shown in Fig. 2. Body j and body L(y) in this figure are in contact at three locations and body j travels over a pair of parallel tracks that are fixed to body L(j). Two of the three contacts between the bodies occur over one rail whereas the third contact occurs over the other rail. Both the bodies are flexible. The interaction dynamics with multipoint contact between flexible bodies and with a relative DOF has not been modeled in the literature and cannot be simulated using the available multibody dynamics software. Single- and multipoint contact studies in the literature9"12 investigate how a flexible body will react to a given set of moving point


A novel phase control of a semi-bridgeless active rectifier (S-BAR) is investigated in order to utilize the S-BAR in wireless energy transfer applications. The standard receiver side rectifier topology is developed by replacing rectifier lower diodes with synchronous switches controlled by a phase-shifted PWM signal. Theoretical and simulation results show that the performance of the proposed S-BAR is appropriate for resonant converters that require power control at the secondary side such as contactless energy transfer systems. To confirm the performance of the proposed converter and control, experimental results are provided for a 1 kW prototype using 3, 6, and 9 inches air gap coreless transformer, which has dimension 2.5 by 2.5 feet, with 120 V input and the output voltage range of 0 to 95 V with a maximum efficiency of 94.4%.

Abstract—The objective of this investigation is to study the effects of induced magnetic field and radiation on MHD heat and mass transfer flow of a steady, viscous, incompressible, electrically conducting, Newtonian fluid over a porous vertical plate in the presence of viscous and magnetic dissipation taking into account the induced magnetic field with a magnetic Prandtl number. The similarity solutions of the transformed dimensionless governing equations are obtained by using perturbation technique. The influence of magnetic parameter (M), radiation parameter (R), chemical reaction parameter (k), Magnetic Prandtl number (Prm), Schmidt number (Sc), thermal Grashof number (Gr) and mass Grashof number(Gm) on Non-dimensional velocity, temperature, concentration and induced magnetic field have been shown graphically. It is found that the effect of magnetic parameter and magnetic Prandtl number is to increase the velocity and temperature fields while the induced magnetic field is negatively increasing with them.

Artificial Intelligence Neural Networks are one of the techniques used for prediction. This ANN is rapidly evolving. At the moment, neural networks are implementing used a variety of techniques. The challenge is the outcome's effectiveness and accuracy, defined by the method, parameters, dataset, and models implemented. Unfortunately, determining how many layers to use, how many filters to employ, and so on might require an extended period. Thus, analysis and review of existing approaches are required to compare many ways that have been utilized and attempt to offer an analysis of the best methods that may be employed, particularly for time series data. The analytical approach employed is one of comparison, in which one technique is comparing to another. The analysis intends to serve as a starting point for further research into ways to improve the performance of prediction algorithms in existing systems, particularly for data derived from regression analysis.

Dilated convolution is used to achieve wide receptive fields in computer vision algorithms such as image segmentation and denoising. Unlike the strided convolution, dilated convolution maintains the resolution of the output feature map same as the input feature map. Thus, the computational complexity can be increased to configure the convolutional neural network (CNN) architecture with the dilated convolutional layer. However, the complexity accordingly introduces additional computation delay and it is strongly required to have a proper way to lessen the computation delay of the dilated convolution. In this paper, we propose the dilated-Winograd convolution to reduce the computational complexity of the dilated convolution. By using the Winograd transform with a dilation rate, the number of pixels in the tile is effectively reduced. The proposed acceleration methods result in an average speedup of 2.043 and 1.456 with dilation rate of 2 and 4 compared to the state-of-the-art implementation.

This paper presents the deployment of an embedded active sensing platform for real-time condition monitoring of telescopes in the RAPid Telescopes for Optical Response (RAPTOR) observatory network. The RAPTOR network consists of several ground-based autonomous astronomical observatories primarily designed to search for astrophysical transients such as gamma-ray bursts. In order to capture astrophysical transients of interest, the telescopes must remain in peak operating condition to move swiftly from one potential transient to the next throughout the night. However, certain components of these telescopes have until recently been maintained in an ad hoc manner, often being permitted to run to failure, resulting in the inability to drive the telescope. In a recent study, a damage classifier was developed using the statistical pattern recognition paradigm of structural health monitoring (SHM) to identify the onset of damage in critical telescope drive components. In this work, a prototype embedded active sensing platform is deployed to the telescope structure in order to record data for use in detecting the onset of telescope drive component damage and alert system administrators prior to system failure.


Causal reasoning has been proposed as critical for deriving impressions from conflicting social-category information, but research to date has relied primarily on participant introspection. To provide a more objective test, we adapted methods from studies of the causal status hypothesis, which asserts that features that 'cause' or 'explain' the presence of other features are more central to mental representation. We hypothesized that 'emergent' attributes (that are part of neither constituent stereotype but are part of the combination, and that tend to characterise incongruent rather than congruent social-category combinations) would possess this 'causal status' – particularly in the case of incongruent-category combinations, because of the presumably greater need for causal reasoning to reconcile incongruent versus congruent categories. Participants generated attributes for targets that belonged to multiple social categories, where the stereotypes associated with these categories were congruent, incongruent, or unrelated to one another (in terms of gender and occupational stereotypes); participants then rated the typicality and goodness-of-fit of target individuals whose descriptions highlighted gender-constituent attributes, role-constituent attributes, or emergent attributes. The results indicated that emergent attributes were more central to participants' representations of the social-category combinations – particularly for incongruent-category combinations – suggesting that causal reasoning is implicated in social-category combination and emergent-attribute generation.


Malay city was one of the oldest civilization in the world which contains unique identity of architecture, the urban design characteristic and the urban form of city planning. Kota Bharu was an example for one of the Malay city which contains the historical building which originally build from 1840 onwards that still exist in peninsular Malaysia. The location of the a few main and significant historical building scattered around the Istana Balai Besar Kelantan proved that, the area was one of the originally Malay city existed in Malaysia. This paper attempt to map an urban form and identify a historical building in Kota Bharu using Multirotor drone. Phantom 3 was used to carry out the aerial mapping and further proceed for 3D modelling at 500meter radius from the centre of study area Istana Balai Besar. the analysis of current pattern of the city, distribution of the land use and building height for the study area shows that the area still preserve the traditional Malay city element and shows the different in urban pattern between the Malay traditional city and area with the influence from the British government and planning for the area. This result proof that the use of drone in mapping and modelling helps in analyse for the urban form and building height for city area in collecting data especially for the aerial mapping. The integration between Urban Planning, GIS, and 3D are highlighted as the platform for the analysis tool and data storage.


Relapse detection is a crucial component of mental disorders treatment and management. In this paper, we present our solution for the ICASSP Signal Processing Grand Challenge e-Prevention track 2 Relapse Detection. We propose an unsupervised learning approach to detect relapse in patients with mental health disorders using anomaly detection with an autoencoder. To this end, we extract features from sleep, physical activity, and physiological data recordings. We train an autoencoder exclusively on non-relapse data. To detect relapses, we calculate the reconstruction error of the autoencoder and use it as an anomaly score. Our team, Emotion, ranked second in the e-prevention challenge with a ROC-AUC score of 0.6 and a PR-AUC score of 0.63 on the testing dataset.


The complex relative electric permittivity of aqueous solutions of various electrolytes has been measured as a function of frequency between 0.3 and 58 GHz by an interferometric transmission method. Appropriate relaxation functions have been fitted to the measured dielectric spectra. The results of this analysis have been interpreted by assuming that in solutions of small ions both effects, kinetic depolarization and dielectric saturation, are present. Formation of ion pairs is not only indicated by an additional dispersion/absorption region at frequencies below 2 GHz. In these cases the parameters characterizing the solvent water are less influenced by the solute than in solutions of similar but fully dissociated electrolytes.

Agricultural land is a natural heritage of each country; therefore the land protection is required. The agricultural land protection is a complex role where the interests of agriculture, industry, housing, transport and the environment should be taken into account. Moreover, it is necessary to consider also the EU legislation because the national laws have to be in harmony with the EU legal acts. Therefore, it is a very hard role to meet all entitled interests together with the requirements of the EU law. Therefore, the adoption of a legal measure should be accompanied by the complex analysis of how the measure would affect the land protection. The Slovak lawmaker has adopted some legislative acts with special measures for the land protection, but they are a focus of regular and frequent amendments.


The APS Upgrade of a multi-bend achromat (MBA) storage ring requires fast bipolar power supplies for the fast correction magnets. The key requirement of the power supply includes a small-signal bandwidth of 10 kHz for the output current. This requirement presents a challenge to the design because of the high inductance of the magnet load and a low input DC voltage (40V). A prototype DC/DC power supply using a MOSFET H-bridge circuit with a 500kHz PWM control has been developed and tested successfully through the R&D program. The prototype achieved a 10-kHz bandwidth with less than 3-dB attenuation for a signal 0.5% of the maximum operating current of 15 amperes. This paper presents the designs of the power and control circuits, the component layout, and the test results.

ABSTRACT Many women living with HIV/AIDS (WL-HIV/AIDS) experience significant mental distress. Although creative arts strategies are well positioned to help support women by inspiring creativity and meaning-making, few arts programs have been implemented and evaluated with this population. The authors conducted a photography project with 30 WL-HIV/AIDS from three United States cities. Participants took pictures to capture their lives with HIV/AIDS and described their photos and stories in group and individual sessions. Using thematic analysis, the authors identified that the project supported women's mental health in four ways by facilitating empowerment and helping women to express themselves, address their mental health with new tools like photography, and process past traumas. Photography projects may help WL-HIV/AIDS understand and manage their mental health.


The article is dedicates to the problem of spiritual continuity of generations, the solution of which allows extrapolating our future. It is claimed that the descendants of white émigré are a thin bridge across the historical rift that separates us from the prerevolutionary Russia, the objective markers that are not deformed by the "new incubatory ideology". The author reveals the spiritual grounds of the life of the Eastern Russian diaspora in different historical periods based on communication with M. P. Taut, a former repatriate from Harbin, involving the documents from her personal archive, publications from journals and newspapers published by the descendants of white émigré at the present time. The key research principle lies in reference to the historical sources. It is substantiated that the restoration of intergenerational link prompts the progress in terms of preservation of the centuries-old values of the Russian civilization and openness to the technological modernization of the XXI century. The author believes that in the era of the oncoming Western globalism, which threatens the national identity and historical integrity of Russia, it is crucial to build the own path of development, adopting the experience of survival and spiritual heritage of the Russian world abroad. The conclusion is made on the need for active study of the documents from the personal archives of the descendants of repatriates, as they are the reservoir of life experience and the source of national self-cognition.

A master camera. scanning-moire method is a moire method in which the grating is replaced by the scanning lines of a television In the present paper, the principle of moire pattern appearance. the effects of thinning out of scanning lines and the relation between moire fringes and strain are studied by the sampling theorem. If deformed model gratings are sampled by a television camera and they are thinned out properly by using an image processing system, the strain distribution in a wide strain range can be analyzed from one picture.


In this paper, we apply an intersectional perspective and test whether resource substitution, which predicts that education will be more strongly related to the health of women than men, is operating among adults included in the 2014 Study of Health and Migration in Mexico (SHMM). Findings revealed modest and somewhat contradictory evidence regarding the potential role of resource substitution. For Mexican women, rates of elevated waist circumference are very high regardless of education level, but for hypertension, there is a strong, negative association with education even after adjustment for controls. Different patterns emerge for Mexican men as regression models show that the probability of both elevated waist circumference and hypertension is higher among the more educated. Overall, results suggest that education is only health protective for women's risk of hypertension. In sum, this work highlights gender specificity in the relationship between education and health in Mexico, and that this relationship varies by health outcome.


The introduction of precision farming technologies using hightech equipment will increase the productivity of rice, reduce its cost, and improve the environment. The use of digital technologies in agriculture is especially relevant in the face of rising prices for seeds, fertilizers and fuel, as it helps to significantly reduce costs and increase the profitability of agribusiness. The paper reviews the use of unmanned aerial vehicles (UAV) in rice cultivation and describes methods for assessing the state of rice crops. Drones are a more versatile and efficient tool for obtaining data on the state of crops of crops compared to information obtained from satellite images. They allow real-time monitoring of the most important indicators of the state of crops, which allows agricultural producers to make timely decisions. The UAV was used to determine the boundaries of the rice system, terrain, microreliefs of checks, moisture of the surface soil layer and the state of rice crops. The studies were carried out on a test site of the Federal State Budgetary Scientific Institution "Federal Scientific Rice Centre" with an area of 327 hectares. The main cultivated crop is rice variety Flagman. The survey was performed by a quadcopter with a Mica Sense Red Edge-M multispectral camera mounted on a fixed suspension. The shooting period using an unmanned aerial vehicle (UAV) was limited to early June and additionally used the Sentinel-2A satellite data covering the entire analyzed period (06.05.2019 – 08.29.2019). To assess the state of rice crops, the normalized relative vegetative index NDVI was used. Based on the NDVI distribution and yield information from the combine TUCANO 580 (CLAAS), a statistical analysis was carried out in fields 7 and 9. Testing of the experimental methodology for monitoring crops in 2019 on the basis of remote sensing of test plots and geoinformation modeling and the statistical apparatus should be considered satisfactory.


The objective of this paper is to describe several figures of merit for estimation of loss in work potential based on the second law of thermodynamics and to evaluate their relative merits for propulsion system analysis and design. The loss figures of merit examined are exergy, gas horsepower, stream thrust, and thrust work potential. Definitions and simplified expressions for evaluating each are presented, and the relationships between these four metrics are expressed via contours on a T-S diagram. A general taxonomy classifying the various work potential figures of merit is suggested. The results indicate that that each method is well suited to a particular type of application, with the most appropriate choice of loss figure of merit depending on the particular application. Finally, thrust work potential is shown to be a special case of gas horsepower, which is in turn a special case of exergy.


A new method for stenosis quantification from 3D X-ray angiography images has been evaluated on both phantom and clinical data. On phantoms, for the parts larger or equal to 3 mm, the standard deviation of the measurement error has always found to be less or equal to 0.4 mm, and the maximum measurement error less than 0.17 mm. No clear relationship has been observed between the performances of the quantification method and the acquisition FoV. On clinical data, the 3D quantification method proved to be more robust to vessel bifurcations than its 3D equivalent. On a total of 15 clinical cases, the differences between 2D and 3D quantification were always less than 0.7 mm. The conclusion is that stenosis quantification from 3D X-4ay angiography images is an attractive alternative to quantification from 2D X-ray images.


Purpose
During rush hours, many passengers find it difficult to board the first train due to the insufficient capacity of metro vehicles, namely, left behind phenomenon. In this paper, a data-driven approach is presented to estimate left-behind patterns using automatic fare collection (AFC) data and train timetable data.

Design/methodology/approach
First, a data preprocessing method is introduced to obtain the waiting time of passengers at the target station. Second, a hierarchical Bayesian (HB) model is proposed to describe the left behind phenomenon, in which the waiting time is expressed as a Gaussian mixture model. Then a sampling algorithm based on Markov Chain Monte Carlo (MCMC) is developed to estimate the parameters in the model. Third, a case of Beijing metro system is taken as an application of the proposed method.

Findings
The comparison result shows that the proposed method performs better in estimating left behind patterns than the existing Maximum Likelihood Estimation. Finally, three main reasons for left behind phenomenon are summarized to make relevant strategies for metro managers.

Originality/value
First, an HB model is constructed to describe the left behind phenomenon in a target station and in the target direction on the basis of AFC data and train timetable data. Second, a MCMC-based sampling method Metropolis–Hasting algorithm is proposed to estimate the model parameters and obtain the quantitative results of left behind patterns. Third, a case of Beijing metro is presented as an application to test the applicability and accuracy of the proposed method.


By virtue of their ability to express a plethora of biologically highly active mediators, mast cells (MC) are involved in both adaptive and innate immune responses. MC-derived Th2-type cytokines are thought to act as local amplifiers of Th2 reactions, including chronic inflammatory disorders such as allergic asthma, whereas MC-derived TNF-α is a critical initiator of antimicrobial defense. In this study, we demonstrate that the transcription factors NFATc1 and NFATc2 are part of a MC-specific signaling network that regulates the expression of TNF-α and IL-13, whereas NFATc3 is dispensable. Primary murine bone marrow-derived MC from NFATc2−/− mice, activated by either ionomycin or IgE/Ag cross-link, display a strong reduction in the production of these cytokines, compared with bone marrow-derived MC from wild-type mice. Detailed analyses of TNF-α and IL-13 expression using small interfering RNA-mediated knockdown reveals that both NFATc2 and NFATc1 are able to drive the expression of these cytokines, whereas neither degranulation nor the expression of IL-6 depends on NFAT activity. These results support the view that high NFAT activity is necessary for TNF-α and IL-13 promoter induction in MC, irrespective of whether NFATc2 or NFATc1 or a combination of both is present.


Cardiac Attacks make worse and threatens the middle aged persons in the world. There are lot of researches are undergoing to make control the cardiac heart attacks. It is difficult to predict the causes and possibilities of heart attacks based on the historical patient records. In data mining, the existing techniques like Decision Tree Classification, Naive Bayesian Algorithm are used to predict the possibilities of heart attacks and their symptoms. However it works well for the structured data. It will not evaluate the unstructured heterogeneous data from various resources. In this proposed work, the analysis performance should be improved to obtain the accurate results. To produce a mechanism for perform predictive analysis about the medical treatments through unstructured heterogeneous data using K Means clustering and SVM Classification. Here the system retrieves the data from the cloud storage. To optimize the data retrieval, here the framework implemented with the Artificial Bee Colony Optimization Algorithm. This helps to obtain the classified results for the preventive measures through the factors from historical data from various cloud resources. To improve the improvements in the analysis based on the mechanism implementation results should be compared with the existing algorithms using UCI dataset of heart attacks in weka tool.

OH POI IC V BEST MIRROR, MIRROR ON THE WALL: Pi AWAKE Adolescent Self-Concept in Four Countries' James G. Cooper University of New Mexico Interest in self-concept studies has continued at a fairly high level, if one can judge from the many reports, projects, and researches 'won the topic. Such studies have frequently attempted to identify similarities and differences between myriad groups: Headstart pupils, advantaged pupils; disadvantaged pupils, pupils of varying ethnic backgrounds, adults in various settings, etc. These studies have been primarily. .concerned with American subjects in typically American institutions. Consequently, much of the work done thus far has a high probability of including on unintended bias: If all the sybjects are American, then at least a portion of the reported selfconcept (or self-esteem) must be due to the American milieu. That is, part of the findings roust include an "American" component. The poet, Robert Burns, pointed up the dilemma: "0 would some power the giftie gie us, fp see oursels as ithers see us." What is needed, then, are referents to self-concept that are quite independent of American culture and customs. It was the purpose of this research to begin a groundwork of cross-cultural data from which new perspectives might be gleaned concerning American selfconcept,. The data base should also be of interest to members of other national groups, In\pursuit of this broad goal, Osgood'.s semantic differential technique, was applied to the measure ofiself-concept, and other relevant perceptions (Osgood, Suci & Tannenbaum, 1957). The tests were translated into Chinese, 1. This research was partialry supported by grants from the University of New Mexido's Research Allocations Committee. -1German, and Spani4h, with careful attention paid to attaining semantic equivalence, rather than a strict word-for -word translation (Mixon & Osgood, 1966). Perspectives On the Problem The literature was examined from three primary points -ofview: 1) the general utility of the variable, self-concept 2) studies across ethnic and cultural groups 3) methodological elements of scales, tests, and procedures. The Utilit of Self-Concept as A Variable There has been general agreement that self -concept is related to significant behavior. KUbitiec.(1970) found support for the theory which "maintains that an individual's behavior is affected by his perceptions." He further found that among college students, his self concept scales predicted academic achievement as well as retention over a 3-semester period. Anderson and Johnson (1971) report supporting findings; self-concept was the single most important variable for predicting high school success in both English and mathematics. In a similar vein, Richmond, Mason, and Padgett (1972) found among college students that those with the more positive self-concepts also had more favorable perceptions of others. Self-esteem seems to be stronger toward and with friends, but much lower in a school context (Gecas, 1972). Carter suspectti that schools can and do affect self-concept: "No careful observer would deny the marginality of many Mexican American children... Surely school curriculums and practices do affect how children see themselves, as well as what they think of educatioand school. personnel... However, hard data in this area are lacking" (1970, p. 54).These studies support the contention that the variable of self-concept influences behavior, and that its study is well-warrented. Ethnic and Cross-Cultural Studies There has been a general drift by educators to feel that minority group persons must inevitably possess self-concepts damaged by abrasive contacts with


Purpose : To study the prescribing pattern of medications used in the management of peptic ulcer disease and to identify and manage the drug related problems. Methods : A prospective interventional study was conducted over a period of nine months in the department of gastroenterology among both in-patients and out-patients, JSS Hospital, Mysuru. Patients diagnosed endoscopically with PUD were enrolled in the study after obtaining inform consent form. Results : A total of 180 PUD patients were included in the study with 108 (60%) out-patients and 72 (40%) in-patients. About 111 (61.66%) participants were started on fixed drug dose combination therapy for H. pylori eradication followed by PPI maintainance treatment for 42.12±5.94 days. In-patients with complicated PUD (UGIB) were administered with PPI 80mg bolus followed by PPI infusion 8mg/hr for a period of 19.5±6.69 hours. Conclusion: Clarithromycin based H. pylori kit is the prevalent therapy used in H. pylori eradication. The majority of drug related problem encountered was drug-drug interactions followed by sub-therapeutic dose and failure to receive maintainance dose of PPI.


Synthesis and Structure of Manganese(II) L-Aspartate Trihydrate, Mn(L-Asp)· 3H2O

Manganese L-aspartate chloride, Mn(L-AspH)Cl, has been prepared from equimolar quantities of MnCl2 and Mn(L-AspH)2 in water. This material can be converted into the title compound by treatment with aqueous KOH, and crystallized as a trihydrate from solutions kept at pH = 7.85. The compound has been characterized by elemental analysis and by single crystal X-ray structure determination. In the crystal, the aspartate dianion functions as a facially tridentate ligand to the Mn(II) center whose octahedral coordination sphere is completed by two water molecules and a carboxylate oxygen atom from a neighboring complex in trans position to the amino group. The stereochemistry of this coordination mode is different from that in the analogous magnesium compound, but similar to that in the cobalt(II) and zinc(II) analogues. The third water molecule is a hydrogen-bonded crystal water.


Cylindrical near-field measurements are suitable for Base Station (BTS) antennas testing due to their fanned-beam radiation patterns. BTS often incorporate large radomes that need to be tested as well to ensure they don't distort the antenna pattern or the reflection coefficient. This increases measurement time because the complete antenna becomes electrically larger. This paper presents a technique to minimize BTS radome testing. The technique is based on measuring the antenna near-field over a ring and a vertical slide to compute the one dimensional versions of the cylindrical and plane wave expansions, for the horizontal and vertical planes, respectively. We show how such reduced expansions can be used to retrieve the far-field pattern on the main planes E and H, as well as its gain. We report measurements with real BTS and radomes reducing the testing times from several hours to minutes.


SUMMARY The focus of this paper is to examine how family and day care are integrated in the child's life in the USA, Russia and Finland. The study concerns parents', teachers' and centre directors' respective contributions to the process of upbringing in day care in these societies. The research is implemented in the light of Bronfenbrenner's ecological theory. The data has been collected by means of questionnaires administered to teachers and parents of 3–5 year old children, as well as by interviews with the directors. The results show that the congruence between parents and teachers in their views concerning upbringing and education was very high within the societies, while opinions between societies differed quite a lot. In the light of these findings, it is easy to conclude that the implementation of early education in centres is strongly influenced by the cultural values in societies.


The invention discloses a method for promoting the quality of tobacco stalks by using liquorice. The method comprises the following steps of: soaking the liquorice into kaoliang spirit to obtain liquorice spirit, soaking the tobacco stalks into the liquorice spirit, airing the soaked stalks at room temperature till the moisture is 20 to 25 percent, storing the tobacco stalks for 1 to 24 hours in a storage cabinet, and performing a next tobacco stalk processing procedure. By the method, glycyrrhetic acid, glycyrrhetinic acid and liquorice flavonoids in the liquorice spirit can enter the internal tissue structure of the stalks; and meanwhile, the color of the cut stalks is deepened by using the relatively deep color of the liquorice spirit, so that the quality of the cut stalks is promoted,and the utilization efficiency of the cut stalks in cigarettes is promoted. Experiments of multiple times prove that the method can make up insufficient fragrance of the cut stalks, reduce the acrimony, improve the aftertaste, reduce thorns, promote the secretion of saliva or body fluid and obviously improve the smoking quality of the cut stalks. The operation method is simple and low in cost, and has good application prospect.

Abstract This article studies how Turkey has adapted itself to the post‐Cold War conditions in functional energy strategy that is practical in connecting Turkey to the several major energy markets and resources. Along with important bilateral agreements, Turkey has managed to connect itself to the main energy markets, including the European energy market, through complex energy projects. In this sense, it can be argued that Turkey has contributed to the emergence of an energy regime in Eurasia.


This article uses a general equilibrium framework to explore the origins and limitations of financial intermediaries. In the model, investors have a generic lending technology that they can improve at a cost. Those who upgrade become intermediaries to exploit their advantage. However, conflicts with depositors will limit the banks' market presence, and they will only lend to moderately endowed firms while bondholders will finance cash-rich corporations. The article also analyzes the extent to which investors adopt the superior lending technique, the nature of bank competition, and how corporate and bank conditions affect interest rates and investment.

Generally speaking, the advanced tuberculous cow is unthrifty, the skin tight and adherent to the subjacent tissues, emaciated more or less, and often changes colour, becoming lighter in shade. The author has noticed that particularly in red cattle, oedema of the intermaxillary space may be present, and enlargement of the glandular system; this is often pronounccd in the region of the tongue, throat, necl;, and when so the patient often makes a variable noise, according to the glands involved, and the degree of interference of respiration. The glands principally attacked in this region are the parotid, sublingual, sub-maxillary, and post-pharyngeal. The aniinal may salivate, and show difficulty in deglutitioo, if there is any ulceration of the mucous membrane of the tongue or pharynx, or protrude the nose and make a decided noise during respiration, should tlle ulceration be in the larynx. If the lesions are confined to the glandular structures, the patient may only suffer inconvenience when feeding or during exertion. In East Devon, where actinomycosis is very prevalent, the writer has found a very large percentage of these enlargements to be due to the


C HAPTER 1 examined the major classical texts that defined and transmitted the physical facts and narrative implications of the labyrinth to later ages. A recurrent theme in that discussion was the maze's inherent duality as the embodiment of simulta neous artistry and confusion, order and chaos, product and process, depending on the observer's (or the writer's) point of view. So far, we have looked at the principle of labyrinthine duality chiefly as it manifests itself within the written tradition, although allusions have been made to the contrasting witness of the visual arts . Now it is time to expand our understanding of the labyrinth's insistent duality and convertibility by confronting directly the dramatic formal conflict between the multicur sal model generally assumed by literature and the unicursal model af firmed by the visual arts . Boethius (ca. 480-524 A.D. ), great reconciler of apparent contradictions, presents Lady Philosophy's remedy for this kind of conflict: "Let us set our arguments against each other and per haps from their opposition some special truth will emerge." 1 So too here : the baffling discrepancy between visual and literary paradigms of the labyrinth, surprisingly enough, offers the key to a fuller appreciation of the idea of the labyrinth in classical and medieval times.


The physical basis for parameterizing topographic stress due to unresolved eddies is examined in a quasi-geostrophic barotropic model. Topographic stress parameterization is shown to represent two effects of eddies: attraction of the flow to a statistical equilibrium featuring topographically correlated mean currents, and dissipation of potential enstrophy. Performance is evaluated by comparing parameterized low-resolution models with explicit high-resolution models.


The tasks achievable by mobile handsets continuously exceed our imagination. Statistics show that the mobile phone sales are soaring, rising exponentially year after year with predictions being that they will rise to a billion units in 2009, with a large section of these being smartphones. Mobile service providers, mobile application developers and researchers have been working closely over the past decade to bring about revolutionary and hardware and software advancements in hand-sets such as embedded digital camera, large memory capacity, accelerometer, touch sensitive screens, GPS, Wi- Fi capabilities etc. as well as in the network infrastructure to support these features. Recently we presented a multi-platform, massive data collection system from distributive sources such as cell phone users1 called PreNotiS. This technology was intended to significantly simplify the response to the events and help e.g. special agencies to gather crucial information in time and respond as quickly as possible to prevent or contain potential emergency situations and act as a massive, centralized evidence collection mechanism that effectively exploits the advancements in mobile application development platforms and the existing network infrastructure to present an easy-touse, fast and effective tool to mobile phone users. We successfully demonstrated the functionality of the client-server application suite to post user information onto the server. This paper presents a new version of the system PreNotiS, with a revised client application and with all new server capabilities. PreNotiS still puts forth the idea of having a fast, efficient client-server based application suite for mobile phones which through a highly simplified user interface will collect security/calamity based information in a structured format from first responders and relay that structured information to a central server where this data is sorted into a database in a predefined manner. This information which includes selections, images and text will be instantly available to authorities and action forces through a secure web portal thus helping them to make decisions in a timely and prompt manner. All the cell phones have self-localizing capability according to FCC E9112 mandate, thus the communicated information can be further tagged automatically by location and time information at the server making all this information available through the secure web-portal.


The author's idea of revising the dictionary of modern Russian political science is a reaction to the mismatch of international and domestic discursive practices. The article deals with a critical attitude to "political culture". This concept was introduced into circulation by scientists at that moment when political theory was in the stage of formation. The problem is that a concept designed to reflect the objective nature of politics is unambiguously related to the nature of culture. Meanwhile, culture and politics are the universal forms of human activity, each of which has its own specificity. Accordingly, the areas of social science also differ. To determine the specifics of political knowledge, the author suggests answering simple questions. What exactly does a political scientist measure: culture by politics or politics by culture; a political element in culture or the cultural (conscious, value, semantic) content of politics? Since the answers reflecting the subject priority of politics for a specialist in this field of knowledge are obvious, it is proposed to use the concepts of "culture of politics", "cultural dimension of politics" and "cultural-political" instead of the concept of "political culture". These expressions neutralize the formalism of the problem of "primary" and "secondary" in relations between culture and politics, politics and culture. From the perspective of the practical realities of Russian politics, the article examines such topical cultural and political aspects of modernity as the crisis of culture, the image of the future, the problem of distinguishing between transcendental and immanent political ideals. According to the author, a common theme for the modern domestic culture of politics should be an orientation towards a citizen as an immanent goal of the development of Russian statehood.


What is the problem and what is known about it so far? Osteoarthritis is the most common type of arthritis in middle-aged and older people. It often occurs in weight-bearing joints such as the knees and hips. The pain may limit ability to get up from a chair, stand, walk, or climb stairs. The pain tends to get worse with activity, so that pain is worst at the end of the day. Treatment is aimed mainly at relieving symptoms and maintaining function. At present, no treatments change the course of the disease itself. Treatments include simple painkiller drugs, weight loss if needed, physical therapy, and regular exercise. In addition, strengthening the muscles around affected joints may help relieve pain and improve function in the short term. The actual relationship between muscle strength and the course of the disease itself, however, is not clear. Why did the researchers do this particular study? To study whether greater strength of the muscle on the front upper portion of the leg (quadriceps muscle) slows down the natural worsening of arthritis in people with osteoarthritis of the knee. Who was studied? 237 men and women with knee osteoarthritis. Their average age was about 64 years. How was the study done? The researchers recruited people with symptoms and x-ray findings of knee osteoarthritis. They tested quadriceps strength of these people using a device that measures muscle force against resistance (isokinetic dynamometer). They took x-rays of both lower extremities to see whether the two bones that meet in the knee joint were in line or crooked in some way (malaligned). They also used special tests to measure the looseness (laxity) of each knee joint. The researchers then followed the participants for 18 months to see whether their knee osteoarthritis stayed the same or worsened. Worsening arthritis was defined as more joint space narrowing on knee x-rays. The researchers compared factors that were measured at baseline (quadriceps strength, knee alignment, knee laxity) among participants who did and did not have worsening joint space narrowing. What did the researchers find? Using data from the entire group of participants, the researchers found no significant relationship between quadriceps strength at baseline and worsening x-ray findings. Among people who had malaligned knees, baseline quadriceps strength was associated with greater risk for joint space narrowing. Among people with lax knees, baseline quadriceps strength also was associated with greater risk for joint space narrowing. What were the limitations of the study? Quadriceps strength was measured only at baseline. How changes in strength and strengthening exercises affect arthritis progression was not tested. What are the implications of the study? Greater quadriceps strength may not protect and could worsen arthritis in some people with osteoarthritis who have malaligned or lax knees. These results do not mean that physical activity or exercise in general is harmful in adults with knee osteoarthritis but suggest that, to maintain strength, special exercise programs should be developed for people with malaligned or lax knees.

Articulation disorder is a speech disorder condition where a person has an obstruction to correctly utter certain sounds. In the case of children, the early assessment and medical treatment for this disorder are most important. An Automatic Speech Recognition(ASR) based system has already been developed for assessment of articulation disorder by the Centre for Advanced Signal Processing (CASP), Department of Electronics, RIT Kottayam in collaboration with All India Institute of Speech and Hearing (AIISH), Mysore. Even though the classification of disordered speech into mild/moderate/severe categories are successfully done by the system, the numerical measure obtained for severe cases is not satisfactory. In this paper, an additional effective method to calculate a numerical measure of articulation disorder is proposed. The first method is to find out the similarity measure between articulation disordered words and their corresponding normal words by Dynamic Time Warping (DTW) of corresponding spectrogram images. Computation of Log Cepstral Distance (LCD) between disordered and normal speech is also done. Evaluation of the system is done using disordered speech in the collected dataset. It is found that spectrogram-based measure gives better results, and hence can be combined with the existing ASR-based system for better objective evaluation of articulation disorder.


'W e have no eternal allies and we have no perpetual enemies. Our interests are eternal and perpetual, and those interests it is our duty to follow', thus spoke Lord Palmerston in 1848, then still the foreign minister of the United Kingdom. 'Nations neither have enemies nor friends but only interests, the national interest' is an aphorism which has been subsequently attributed from Winston Churchill to Henry Kissinger. The most basic course on International Relations' theory anywhere does not fail to impart the lesson that the national interest drives the behaviour and determines the relationship of any country. Yet, we have Professor Kanti Bajpai, currently posted at the Lee Kuan Yew School of Public Policy at the National University of Singapore, musing in a book titled India Versus China: Why They Are Not Friends. Instead of being rigorous, Professor Bajpai gets a little playful and comes up with four Ps to explain the bitterness between India and China. These four Ps are their negative perceptions of each other, their difficulties on their perimeter (border), their competing partnerships with or against the United States and the Soviet Union (later Russia), and the increasing power asymmetry between them. However, if Professor Bajpai's concluding answer to the question Why They (India and China) Are Not Friends is that 'mutual perceptions and the power asymmetry may be the most serious problems between the two countries' (p. 6), then he has got it wrong. In fact, on the contrary, mutual perceptions and power asymmetry do not really matter when it comes to the relationship between two countries. For example, how is it that Pakistan, a country with the same colonial history and similar cultural values (except for religion) as India and with even a bigger power asymmetry than India, has been chums with China almost since its independence? Furthermore, how come communist China and capitalist United States, each having mostly negative perceptions of the other, suddenly changed tack and made up with each other in 1971 whereas comradely China and the Soviet Union had a break-up around the same time? The answer, particularly on perception, is that perceptions do not remain static; rather they change over time. Thus, they do not matter much, certainly not as much Professor Bajpai thinks it to be a reason for the acrimony between India and China. Perceptions, and even interests, change because 'minds [of the leaders] can be changed, new leaders can come to power, values can shift, new opportunities and dangers can arise'. In any case, it is Strategic Analysis, 2022 Vol. 46, No. 1, 125–127, https://doi.org/10.1080/09700161.2021.2020444


This paper presents a monocular vision-based, unsupervised floor detection algorithm for semi-autonomous control of a Hybrid Mechanism Mobile Robot (HMMR). The paper primarily focuses on combining monocular vision cues with inertial sensing and ultrasonic ranging for on-line obstacle identification and path planning in the event of limited wireless connectivity. A novel, unsupervised vision algorithm was developed for floor detection and identifying traversable areas, in order to avoid obstacles in semi-autonomous control architecture. The floor detection algorithms were validated and experimentally tested in an indoor environment under various lighting conditions. INTRODUCTION Field mobile robots are extremely useful for operating in hazardous environments and performing urban search and rescue missions. To enhance mobility in unseen environments, most mobile robots are wirelessly operated. Although mobile robots have much potential in hazardous and hard-to-access environments, wireless connectivity has always been a limiting factor in the full-scale utilization of robots in these scenarios [1]. As fully autonomous robots are reliable only in controlled environments, semi-autonomous control based on onboard sensing and computing remains the only viable means to reduce dependence on wireless connectivity. In the absence of connectivity with a human operator, the robot's most critical computational task is obstacle identification. Since the robot may encounter many different types of obstacles, an alternative to identifying the obstacles themselves is to identify traversable areas in their field of sensing and then treat everything else as an obstacle. Identification of the ground plane in a video feed for visual navigation of robots has attracted many researchers all over the world [2–6]. Although detecting the ground plane is easier with depth sensors, it is computationally more expensive to process 3D point cloud data than a 2D image. Researchers have often resorted to monocular vision processing to overcome such constraints. Identification of traversable areas by floor/road detection is a key technique in semi-autonomous robotic navigation. Sensors such as RGB cameras, depth cameras, radar rangers, and LIDAR are often used to map surrounding environments, detect objects, and extract traversable regions from the current view field. Algorithms for detecting traversable regions can be classified into two categories: supervised algorithms and unsupervised algorithms. Supervised algorithms build machine learning classifiers that use training data such as color [7], texture [8], and shape [9] to model image appearance. These classifiers are then used to identify segments in test images [10,11]. However, such methods are limited by the quality of the training dataset. The performance of classifiers in identifying new scenes (i.e. scenes not included in training data) is very poor. Unsupervised algorithms are based on the weak assumption that the segment that the robot maneuvers on is the floor, while any other objects visible in the image are treated as obstacles. In road region detection methods, texture and color features with homogeneous road appearance constraints are used to segment the view field [12]. Such methods also use depth cues in stereo vision [13] or image homographic cues in monocular [14] camera vision. Road boundary detection algorithms often use special filters or detailed road models to estimate the edge of the road, combining texture and color cues [15]. Detecting the vanishing point is a key technique in these methods. Chang et al. [16] combined region segmentation with road boundary detection by using voting mechanism methods to improve the segmentation performance in both indoor and * Authors contributed equally; **Corresponding author – email@example.com Proceedings of the ASME 2017 Dynamic Systems and Control Conference DSCC2017 October 11-13, 2017, Tysons, Virginia, USA


The normal-state resistivity rho (T) and longitudinal magnetoresistance of superconducting A15 Nb3Au and Ti3Sb compounds have been measured. The resistivities of these compounds have been measured from just above their superconducting transition temperature (Tc) to room temperature. The magnetoresistance has been measured up to a field of 4.5 T. At high temperatures (T>200K) their resistivities show a non-linear behaviour with temperature which is a characteristic feature of many A15 compounds. However, at low temperatures (T<40K), the rho (T) of these compounds show a T2 dependence which was so far seen only in high-Tc A15 compounds. The data are fitted to several theories which try to explain the low- and high-temperature resistivities of A15 alloys. The magnetoresistance data show a linear dependence on field which is not very well understood.


The article sets the task to consider the main characteristics of the innovative personality as producers and consumers of innovative products. As a producer of innovative products, innovative personality need to have creativity, ability to take risks, tolerance of uncertainty. The personal characteristics of consumers of innovative products include the desire for novelty, ability to take risks, and the dominance of the emotional component when making decisions over rational. The author analyzes the possible negative consequences of purposeful formation of the above-mentioned personal qualities, such as increased numbers of people with mental regulation and behavior, the growing number of risks and instability in society, as well as opportunities for manipulating the minds of consumers.

The patient as a whole is the problem in medicine and should be so considered whenever illness attacks him. He is an acting and thinking being subject to many minor and major physical, emotional and psychic reactions. His normal functional activity and the correlation of its various factors depend on his vegetative and voluntary nervous systems, his endocrine products and various electrolytes. It is affected by stimuli which arise in the viscera, superficial body structures and the cortex. Correlation is such that activity in his physical body may be modified by his thinking and emotions, and his thought and emotions may be affected by stimuli which arise in his physical body. Normal man is so constructed that all action is harmonious, but disharmony may result when disturbances arise in either his physical or his emotional sphere. In the construction of man's nervous systems there are many ganglia which act as centers for the reception and transmission of impulses from one organ or structure to another. Ganglia in which action between the voluntary and vegetative nervous systems and between the nervous and emotional systems is correlated are situated in the diencephalon. Here are centers which influence many activities, among which are carbohydrate metabolism, respiration, circulation, digestion, body temperature, water balance, dilatation and contraction of the pupil, erection of hairs, secretions of the endocrine glands, and the regulation of the lacrimal, salivary and sweat glands. Here is located the hypothalamus, in which impulses from the visceral and somatic structures meet and are relayed so as to influence various functions. Impulses from here also are transferred to the cortex, and those which originate in the cortex may be relayed to the viscera and superficial structures. These centers make it possible for man's physical and emotional mechanisms to react as a well balanced, functioning organism in health, and to act inharmoniously in case of disease. Man in his normal state is under the influence of many emotions of a minor nature-some pleasing, others displeasing-to which he responds promptly. For example, so simple a setting as a beautifully appointed table, food served in an appetizing manner and pleasing company at mealtime all stimulate the appetite and digestion. Disgusting conditions and unfavorable companions, on the other hand, interfere with digestion; but fortunately equilibrium may be quickly restored. Major emotions, if temporary, may cause only temporary reactions. Cannon (1) showed how fear, hunger, pain and rage by acting through the vegetative


Abstract
Objectives: This study aimed to investigate provision of dental care services before and during the COVID-19 pandemic in western Türkiye.
Materials & Methods: Data was screened between 1 December 2018-1 June 2022 from the hospital database of Izmir Training Dental Hospital, Izmir, Türkiye. All dental procedures including oral and radiographic examination, dental fillings, restorative/reconstructive treatments, extraction, endodontic treatment, treatment of parafunctional habits, periodontal treatment, emergency dental treatments. Data envelopment analysis model was applied to measure the efficiency of decision-making units.
Results: Total number of dental and auxiliary staff worked in the selected hospital was 84±15 (mean±SD) and 105±0 (mean±SD) respectively and the number of active dental chair was 150±0 (mean±SD). While oral examination was the most performed dental care services, root canal treatment and extractions were the least effected treatment modalities during the selected years. When the scale efficiency value is examined, it is observed that the most effective year was 2019 (scale efficiency value: 1), the second effective year was 2020 (0.987), and the third effective year is 2022 (0.886), and 2021 (0.875) was the least effective year.
Conclusion: Non-aerosol generated procedures were least effected oral care services during the pandemic. It is concluded that COVID-19 pandemic has caused marked impairments in routine dental care services during the year 2020 and 2021. The policy makers should be well-prepared for future pandemics to dedicate uninterrupted dental care services as well as public health.


The 7-DoF redundant manipulator with offset links and symmetrical structure is applied in the space station. The analytical solution of the inverse kinematics(IK) is difficult when considering the joint limits. This study proposes a joint limit optimal IK solution based on the optimization of the fixed joint angle parameters. The analytical method of fixed joint inverse solution is combined with the numerical method of joint limit optimization. This semi-analytical method converges to a definite solution with a closed form and have symmetry to avoid the non-conservative of the pseudo-inverse solution. Simulation results verify the effectiveness of the IK algorithm.


We have applied intein-mediated peptide ligation (IPL) to the use of peptide substrates for kinase assays and subsequent Western blot analysis. IPL allows for the efficient ligation of a synthetic peptide with an N-terminal cysteine residue to an intein-generated carrier protein containing a cysteine reactive C-terminal thioester through a native peptide bond. A distinct advantage of this procedure is that each carrier protein molecule ligates only one peptide, ensuring that the ligation product forms a sharp band on sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). We demonstrate the effectiveness of this approach by mutational analysis of peptide substrates derived from human cyclin-dependent kinase, Cdc2, which contains a phosphorylation site of human c-Src protein tyrosine kinase.


Phosphine-oxide-(PO)-based optoelectronic materials are attracting increasing attention owing to the unique advantages of P = O groups in modulating the molecular configuration, excited-state properties, and intermolecular interactions. P = O groups are also effective for the molecular design of high-performance luminescent materials. In this review, the research progress of pure-organic PO materials for light-emitting applications with high radiation is summarized. After a brief introduction about the luminescent mechanisms and the functions of P = O groups, this review focuses on the material design and structural-property relationships, especially the influences of P = O groups on the material performances, which are divided into three chapters according to the mechanisms of fluorescent (FL), thermally active delayed fluorescent (TADF), and charge-transfer-(CT)-based long-afterglow materials. It was shown that the electron-withdrawing effect and the insulating character of the P = O joint could improve the electrical properties and enhance inter – and intramolecular CT without remarkably changing the emission color, making it almost 'ideal' for blue emitters. The steric hindrance of 3D PO molecules further suppressed the quenching effects for emission efficiency improvement. These superiorities guarantee that the pure-organic PO system is one of the best fluorescent materials for diverse applications.


Abstract Dental implantation treatment has developed into one of the most successful prosthetic technologies. A critical progress made in this area was the development of biocompatible materials to enable an engineered device (implant) to integrate within its surrounding bony tissues. Titanium and its alloys have been widely adopted as such materials due to their excellent biocompatibility. However, their mechanical properties largely differ from those in host bony tissues, which is problematical in osseointegration and bone remodeling. The challenge to face in prosthetics is to develop both biologically and mechanically compatible biomaterials for this purpose. Few existing research has been reported to develop an optimized design of functionally graded material (FGM) dental implant for promoting a long-term success. One of the authors of the present Contributions has previously designed a new FGM dental implant coating graded in axial direction from titanium at the apex to collagen at the basis of the dental implant. The aim of this investigation is to design a new gradation direction of FGM dental implant coating as well as studying the effect of coating thickness on the maximum von Mises stresses in bone adjacent to the coating layer. The gradation of the elastic modulus is changed along the longitudinal direction. Stress analysis using a finite element method showed that using a coating of 150 μm thickness, which is functionally graded from titanium at the outer shell adjacent to the bone to collagen at the inner shell adjacent to the implant, will reduce the maximum von Mises stress by 16 % and 13 % compared with the common conventional coating materials such as collagen and hydroxyapatite coatings, respectively. However, using FGM coating graded from hydroxyapatite at the outer shell to titanium at the inner shell reduces the maximum von Mises stress by 8 % and 5 % compared with collagen and hydroxyapatite coatings, respectively, but this gradation can improve the biocompatibility and can also achieve a full integration of the implant within the living bone, which increases the life of the implant.

Large pore MCM-41 silica with the pore diameter of 5.0 nm was chemically modified by bonding monomeric-type ligands, such as trimethylsilyl, butyldimethylsilyl, and octyldimethylsilyl, as well as polymeric-type 3-aminopropylsilyl, (hexanoyl-3-aminopropyl)silyl, and octylsilyl ligands. The obtained materials were characterized using elemental analysis, high-resolution thermogravimetry (TGA), and nitrogen adsorption at 77 K in a wide range of pressures. Surface coverages of bonded ligands were between 2.5 and 3.0 μmol/m2. It was shown that pore diameters of the samples studied decreased systematically with the increase in size of ligands. The modified materials exhibited narrow and monodisperse pore size distributions, indicating that the chemical bonding procedure did not diminish the structural ordering of the MCM-41 support. TGA data showed that the surface affinity to water was strongly dependent on the structure and functionality of the bonded species. Nitrogen adsorption data provided additional infor...


Abstract : One of the topics that has emerged during the last decade in the policy agenda of national governments and international organizations is the design of policies that seek long-term economic growth while improving and sustaining the environment. The analysis of this type of policies is usually based on macroeconomic models which link changes in policy instruments (e.g., fiscal policy, pollution taxes, carbon permits, energy subsidies) to some outcome measure such as aggregate output or consumption. Critical assumptions within these models are related to the dynamics of technology-related-variables, such as total factor productivity, or the carbon intensity of the economy. Usually, these dynamics are defined exogenously, or endogenized by formalizing the effects of changes in input prices or R&D investments. Nonetheless, the micro- process of technology adoption, where decentralized heterogeneous economic agents interact and share information about the dynamics of the economy and the characteristics of new technologies, has been always ignored. Yet, it is this process which is behind the diffusion of new technologies and ultimately the dynamics of macro variables such as the carbon intensity of the economy.


This paper studies the separation and recovery of copper and aluminum from waste copper clad aluminum wire with HNO3 or H2SO4-H2O2 solution.The copper is recovered as soluble cupric salt,but the aluminum does not take part in the reaction because of passivation.The reaction rate of the aluminum and acid is low,so that they are separated.The both reagents are compared and the industrialization of this separation is discussed.


Background: It is not known whether the redox status of cryptochrome affects circadian clock resetting. Results: Blocking cryptochrome photoreduction does not impair cryptochrome-mediated Timeless degradation and light can induce a conformational change in cryptochrome with oxidized flavin. Conclusion: Cryptochrome can mediate its function in either oxidized or reduced form. Significance: This study provides novel insight into cryptochrome photosignaling. Cryptochrome (CRY) is the primary circadian photoreceptor in Drosophila. Upon light absorption, dCRY undergoes a conformational change that enables it to bind to Timeless (dTIM), as well as to two different E3 ligases that ubiquitylate dTIM and dCRY, respectively, resulting in their proteolysis and resetting the phase of the circadian rhythm. Purified dCRY contains oxidized flavin (FADox), which is readily photoreduced to the anionic semiquinone through a set of 3 highly conserved Trp residues (Trp triad). The crystal structure of dCRY has revealed a fourth Trp (Trp-536) as a potential electron donor. Previously, we reported that the Trp triad played no role in photoinduced proteolysis of dCRY in Drosophila cells. Here we investigated the role of the Trp triad and Trp-536, and the redox status of the flavin on light-induced proteolysis of both dCRY and dTIM and resetting of the clock. We found that both oxidized (FADox) and reduced (FAD⨪) forms of dCRY undergo light-induced conformational change in vitro that enable dCRY to bind JET and that Trp triad and Trp-536 mutations that block known or presumed intraprotein electron transfer reactions do not affect dCRY phototransduction under bright or dim light in vivo as measured by light-induced proteolysis of dCRY and dTIM in Drosophila S2R+ cells. We conclude that both oxidized and reduced forms of dCRY are capable of photosignaling.


The Arctic is warming at a rate of almost twice the global average, promoting both soil organic matter (SOM) mineralization and plant photosynthesis. Plants release labile organic compounds into the soil that may stimulate SOM decomposition. This so-called 'rhizosphere priming effect' has the potential to accelerate SOM losses from permafrost soils under warming, but the controls on its magnitude are unclear. For instance, the magnitude of the priming effect may depend on the chemical composition of native SOM, with some compounds being more prone to priming than others and other compounds inhibiting priming.


The method of Fama-French three factors models was used to group the 250 listed companies which had undergone split-share structure reform from 2005 to 2006.And also the method of event studies combined with regression analysis were applied in the analysis,mainly focusing on the abnormal return of the portfolio,equally weighted and valuedly weighted,to illustrate the general study on the impact of split-share structure reform upon China's stock market.


The origins of copper-based metallurgy on the island of Cyprus, which became the main supplier of the metal in the Late Bronze Age in the Mediterranean and whose name became associated with the metal, is relatively obscure. While metal extraction and metal artefacts became increasingly important in the broader Near East, early metallurgy on Cyprus remains poorly known, and it is often postulated that metals were of limited importance on the island prior to the Philia phase. Here we present a unique context from the Late Chalcolithic (ca. 2800-2400 BC) from the excavations at Chlorakas- Palloures that has considerable ramifica-tions for this debate.


The process of ferroptotic death is characterized by the overwhelming, iron-depending accumulation of lethal lipid ROS. Unlike other forms of apoptotic and non-apoptotic death, this requirement for ROS accumulation appears to be universal. Redox cycling is a characteristic of transition metals such as iron (Ferritin Fe 3+ ⇄ Ferrous Fe). Iron via the Fenton reaction can exacerbate the consequences of hydrogen peroxide (H2O2) production, leading to the generation of hydroxyl radicals. The superoxide ion can participate in regenerating ferrous iron that is required for the Fenton reaction. An excess of iron is toxic due to its ability to engage in redox cycling and promote free radical formation. Super oxide anion generation; O2 → ・O2 . Hydrogen peroxide production; ・O2 + 2H + + e→ H2O2. Haber-Weiss reaction; H2O2 + O2 → ・OH + OH + O2. Fenton reaction; Fe 2+ + H2O2 → Fe 3+ + OH + ・OH. Reduction to Fe(II); Fe + ・O2 → Fe 2+ + O2. Ferritin is stable in iron-rich conditions, whereas it is rapidly degraded under conditions of iron starvation and ferritin degradation can be led. New blood vessel formation in angiogenesis is fundamental to tumor growth, invasion, and metastatic dissemination. Iron deficiency will lead to the dysfunction of immune system, metabolic disorders, myasthenia and anemia, whereas, excess iron also damages several vital organs. Thus, iron is essential for multiple cell functions, but is also potentially deleterious reasons of its ability to generate free oxygen radicals, iron balance by continuously recycling and reusing cellular iron, storage in ferritin, and export through ferroportin protecting cells from free iron toxicity. However. the exact molecular mechanism involved on iron imbalance in development for tumor cells and the iron overload-mediated induction of apoptosis are required to be explored in future.


Well-defined star polypeptides were successfully synthesised by initiation of γ-benzyl-L-glutamate N-carboxyanhydride (NCA) from polypropylene imine (PPI) dendrimers. The dendrimer generation and the dendrimer to NCA ratio were systematically varied to afford a range of star shaped architectures with a maximum of 8 to 64 poly(γ-benzyl-L-glutamate) (PBLG) arms. High molar masses up to 500 000 g mol−1 were achieved that were otherwise unobtainable for the analogous linear polypeptides in the absence of the dendrimer core. By deprotection the PBLG star polypeptides were converted into poly(L-glutamic acid) (PGA) star polypeptides. Various concentrations of rhodamine B could be loaded into the polypeptide star architectures dependent on the number of PGA arms and the length of the grafted polypeptide chain produced. Furthermore, the polypeptidic nature of PGA-grafted dendrimers ensures their responsiveness, through controlled degradation, to the target enzyme thermolysin. An enzyme-responsive release mechanism was devised and demonstrated in which rhodamine B payload was released upon incubation with thermolysin but not the control enzyme chymotrypsin. The rate and extent of rhodamine B release was dependent on the composition of the hybrid material, which can be readily tuned to provide highly specific temporal and spatial controlled release.


The adverse effects of long‐term exposure to lead dust on renal tubular functions were studied in 39 male and 7 female workers in a secondary lead refinery. Laboratory examinations showed low or moderate lead absorption levels. The N‐acetyl‐β‐D‐glucosaminidase (NAG) activity in urine showed significant correlation with each of the lead exposure indices. NAG activity increased remarkably in lead workers with blood lead (PbB) above 80 μg 100g−1.


lactamase produced by Escherichia coli K-12 W3630 R751}, two water-soluble, acidic, labile substances exhibiting the strong inhibitory activity against the enzyme were obtained from the cultured broth of a streptomyces, designated MC696-SY2. The strain was isolated from a soil sample collected in Okazaki-city, Japan, and classified as Streptomyces fulvoviridis MC696-SY2. The inhibitors isolated are not completely pure at present, but have an extremely strong inhibitory activity against /?-lactamase. Therefore, in the present paper, the production, purification and biological properties are described. The activity of the inhibitors, MC696SY2, was determined by the iodometric titration method and by the agar plate method. (1) Iodometric titration method : A solution of 0.1 ml of 0.1 M phosphate buffer (pH 7.0) containing the inhibitor, 0.25ml of


Artificial intelligence (AI) techniques are used to model human activities and predict behavior. Such systems have shown race, gender and other kinds of bias, which are typically understood as technical problems. Here we try to show that: 1) to get rid of such biases, we need a system that can understand the structure of human activities and; 2) to create such a system, we need to solve foundational problems of AI, such as the common sense problem. Additionally, when informational platforms uses these models to mediate interactions with their users, which is a commonplace nowadays, there is an illusion of progress, for what is an increasingly higher influence over our own behavior is took for an increasingly higher predictive accuracy. Given this, we argue that the bias problem is deeply connected to non-technical issues that must be discussed in public spaces.


Abstract : The physical and chemical characteristics of synthetic polymers are related to the type and ratio of functional groups distributed throughout the polymer. With polyvinyl chloride-acetate copolymers and cellulose esters, acetate comprises the major ester group commonly incorporated to impart certain desirable properties essential to the proper performance of fabricated products. Many organic coating systems are formulated from resins containing acetate groups. The report describes a GLC procedure for the determination of vinyl acetate in vinyl chloride-acetate copolymers and the acetyl content of cellulose resins. The procedure for the analysis of both types of material follows essentially the same course, namely, saponification and acidification of the polymer, followed by gas chromatography of the liberated acids.

Many of the manufacturing and evaluation techniques that are currently used for rocket engine component production are traditional methods that have been proven through years of experience and historical precedence. As we enter into a new space age where new launch vehicles are being designed and propulsion systems are being improved upon, it is sometimes necessary to adopt new and innovative techniques for manufacturing and evaluating hardware. With a heavy emphasis on cost reduction and improvements in manufacturing time, manufacturing techniques such as Direct Metal Laser Sintering (DMLS) and white light scanning are being adopted and evaluated for their use on J-2X, with hopes of employing both technologies on a wide variety of future projects. DMLS has the potential to significantly reduce the processing time and cost of engine hardware, while achieving desirable material properties by using a layered powdered metal manufacturing process in order to produce complex part geometries. The white light technique is a non-invasive method that can be used to inspect for geometric feature alignment. Both the DMLS manufacturing method and the white light scanning technique have proven to be viable options for manufacturing and evaluating rocket engine hardware, and further development and use of these techniques is recommended.


Based on RNG k- e turbulence model and porous media,3D numerical simulations were carried out for the inner flow field of SCAL natural draft cooling tower,and the influence of wind speed and ambient temperature on the ventilation rate was analyzed. The results indicate that the operating condition presents deteriorated when the wind velocity is 6m / s and ambient temperature is 42℃. The optimization measure of installing nozzle segments and leading source gas into the air cooling tower was put forward,and the performances before and after optimization were simulated and compared. It turns out that after optimization,the flow field inside the tower is improved,and the ventilation rate is increased. Comprehensively considering the optimization results,operation cost,and maneuverability,installing 48 nozzles with the 0. 005 kg / s flow rate in the air intake section is the optimal scheme,and in this case the ventilation rate is increased by 8. 258 9%. The optimization is of enormous significance on solving the problem of insufficient output for power plant in summer.


Abstract The phase relations in the system MgO-V 2 O 5 -MoO 3 were studied and the subsolidus region of the phase diagram was constructed. The new compound Mg 2.5 VMoO 8 was discovered on the join of MgMoO 4 -Mg 3 V 2 O 8 . Mg 2.5 VMoO 8 crystallizes in the orthorhombic space group Pnma (No. 62) with cell dimensions a = 5.0515(1) A, b = 10.3455(2) A, c = 17.4683(4) A, and Z = 6. The structure is a framework of MoO 4 and VO 4 tetrahedra with linking octahedral and trigonal prismatic MgO 6 groups. The molybdenum and vanadium cations preserve their highest oxidation state, and the electrical neutrality of the crystalline lattice is maintained by partial occupancy of magnesium sites. Simple quasibinary equilibria were established between MgMoO 4 and MoV 2 O 8 , V 2- x Mo 2 x O 5 , MgV 2 O 6 , and Mg 2 V 2 O 7 .


Experiments have shown the novel combination of laser optical pumping and velocity-changing collisions (between active- and buffer-gas atoms) to be very effective in producing vapors with high atomic or nuclear polarizations. This paper presents a theory which has proven successful in analyzing these experiments. The theory predicts the amount of polarization attainable for particular experimental conditions and establishes the general criteria for optimum polarization. The theory is based on sets of coupled rate equations, which contain terms describing the pumping process (i.e., stimulated absorption or emission), radiative branching, relaxation, and velocity-changing collisions. The collision terms are written in the strong-collision approximation, which assumes that a single collision, on average, thermalizes the velocity distribution. Expressions are derived for the polarization and level populations.
