Defects in SF/sub 6/ gas-insulated switchgear can result in breakdown of the gaseous insulation. Therefore, it is important to detect defects, such as protrusions and particles, in time and to determine their risk for a possible breakdown. For on-line PD detection, the UHF method has proven to be a sensitive method. Unfortunately, the propagation path of the electromagnetic waves from the location of the defect to the UHF coupler influences the magnitude of the UHF signals: the UHF signals attenuate, mainly due to reflections at the different components. As a result, several UHF couplers are required to reach enough sensitivity. In this contribution a transmission line model has been used to estimate the signal reduction of each GIS component. This has been used to determine coupler locations to reach certain sensitivity, which has been verified using the CIGRE sensitivity check.

We present photometric and spectroscopic observations of the late afterglow of GRB 000911. We detect a moderately significant re‐brightening in the R, I and J lightcurves, associated with a sizable reddening of the spectrum. This can be explained through the presence of an underlying supernova, outshining the afterglow ∼ 30 days after the burst event.


A novel tri-tracking method for tracking objects is proposed. The tracker trains three support vector machines with labelled frames, in which an object is represented using three independent feature histograms. Based on the confidence map created by each classifier, the object position is given by the mean shift. Experiments on several video sequences show the robustness and accuracy of the proposed method.


Asymmetry of the frontal bristles and postocular setae was studied in samples from natural populations and laboratory colonies of Anastrepha sp. 1 aff. fraterculus, of A. sp. 2 aff. fraterculus, and in F1 hybrids obtained from laboratory reciprocal crosses. Natural populations were sampled in a zone of sympatry and in two geographically distant regions with different climatic conditions. Asymmetry was scored as the differences between the number of bristles and of setae on the right and left sides of the head, males and females analyzed independently. The two traits exhibited variability according to the model of fluctuating asymmetry (FA). No significant differences among samples were found in the FA of frontal bristles. A significant FA was observed for the postocular setae of A. sp. 1 males from a southern population (Vacaria, RS) as compared to the asymmetry exhibited by males and females of some other samples. No significant differences in FA were observed among the interspecific hybrids and the laboratory samples of both parental species. The higher FA found in the males from Vacaria was attributed to climatic conditions prevailing in that region. The absence of a higher FA in hybrids may be related to the relatively recent evolutionary history of the two species.


In this paper, we prove the existence of at least three weak solutions for Neumann doubly eigenvalue elliptic systems involving the (p_1, . . . , p_n )-Laplacian. The approach is based on a recent three critical points theorem obtained by B. Ricceri [9]. We also give some examples to illustrate the obtained results.


Rizatriptan benzoate is a selective 5-Hydroxy Triptamine1B/1D (5-HT 1B/1D) receptor agonist, used as an antimigraine 1 agent. Two simple, precise, accurate and economical UV spectrophotometric methods 3 have been developed and validated for the routine estimation of Rizatriptan benzoate (RB) in bulk drug and pharmaceutical preparations. The drug showed maximum absorption at 280nm and obeyed Beer-Lambert's law in the concentration range of 0.5-80 µg/ml at 280nm. From the same spectrum AUC was measured. In AUC method the drug showed linearity in the concentration range of 0.5-80µg/ml. The linear regression equations were calculated to be y=0.0141x+0.016 (R 2 =0.999) for D0 at 280nm, y=0.140x+0.020 (R 2 =0.999) for AUC. The results of estimation of marketed tablet formulations were found to be 101.06±0.230-100.77±0.520 with their %RSD less than 2. Recovery studies were carried out by addition of known amount of standard drug (80, 100 and 120% of labeled claim of a tablet) to the preanalyzed tablet solution. The % recovery was found to be 103.423±0.921-101.02±0.952, which indicates accuracy and reliability of the validated method as well as non-interference from excipients to the developed method. The intraday and inter day assay was within 2%. The methods were then validated statistically as per the ICH guidelines.


It is well known that the long distance telecom service providers suffered heavy damage in the aftermath of the telecom bubble. What is it about the telecom industry that drove participants to fall victim of the bubble dynamics despite historical understanding of the destructive consequences of past bubbles? Was the bubble simply the result of a "perfect storm", or was it an inevitable reflection of industry dynamics? To what degree did the bubble arise from irrational exuberance and misperception of demand growth, and to what degree did it simply reflect pathological emergent behavior arising from individually rational actors? The answer to such questions are interesting historically, but may also help provide insights for regulators and enterprises. The objective of the analysis described in this paper is firstly to use system dynamics to characterize the telecom bubble phenomena, secondly to analyze and understand the mechanism of the telecom bubble, and thirdly to utilize the model to make preliminary recommendations that may help to lower the risk of similar phenomena in the future. The model provided insight into the impact of factors such as technological advancement, misinformation concerning demand growth, competition among network service providers, and the impact of demand forecasting techniques.


Real-world materials exhibit highly nonlinear mechanical behavior, but computer animation often neglects such nonlinearities. Hyperelasticity, or strain-dependent material stiffness, is one of the clear sources of nonlinearity. Correctly modeling real-world materials would require capturing strain-dependent elasticity, but hyperelasticity induces stiff differential equations that may complicate simulation, in particular for real-time computer animation. In this paper, we propose a method based on constrained optimization for the simulation of hyperelastic materials. The key novelty of our method lies on limiting elastic energy to model extremely nonlinear elasticity within a common linear co-rotational formulation. Our method is designed on a hexahedral FEM discretization to avoid locking phenomena, and is capable of solving together energy-limiting and frictional contact constraints. We show that our approach enables the simulation of a large range of hyperelastic material behaviors.


five, and six), but both sets of rates were somewhat lower than expected when compared with previous work on returns to education in Great Britain. The authors conclude that returns seem to be much higher at the middle pre-degree level than at the degree level itself (although the large initial investment required at higher levels reduces the rate of return) and that there is a surplus rather than a shortage of highly educated manpower available to the private sector of the economy. These conclusions are consistent with the much discussed "braindrain" phenomenon experienced by the British in recent years. Additionally, the present earnings structure, reflecting the extra earnings accruing to more highly educated persons, does influence the decision to remain in school and acquire a degree or diploma. These interpretations are quite tentative, however, and any final conclusions must await completion of the large-scale interfirm study. The authors speculate that the higher the rates of return to education in qualifying for a specific occupation, the more likely it is that news of the shortage will filter down to the schools. Empirical evidence on this point is sparse, but on the basis of American experience, there may be some reason to doubt whether possession of such knowledge results in the appropriate reaction (for example, the failure of medical schools to provide a more rapidly increasing supply of doctors in the face of rising returns to medical education). In this report, the authors have provided very little data relative to the firm's economic performance and, therefore, are unable to relate productivity or profitability to education of the labor force. This situation is apparently due to the reluctance of firms (even the most cooperative ones) to provide economic information even under the secrecy conditions established by the researchers. Furthermore, Blaug, Peston, and Ziderman found that firms have not recognized the need for conscious manpower planning, do not maintain adequate personnel records, and undervalue the personnel function relative to such other functions as finance, production, and sales. On the basis of this research in the United Kingdom, it appears that practitioners are far more reluctant than academicians to accept the notions that the purchase and sale of labor involves significant costs and that labor costs are in many ways fixed costs-in short, the capital concept applied to labor.

1-Acyl-4-benzylpyridinium salts 4 containing nonnucleophilic anions X– such as CF3SO3–, FSO3–, and BF4– can be generated quantitatively and in situ from 1-acyl-4-alkylidene-1,4-dihydropyridines 1a–f and the corresponding acid, HX. The BF4– salts reveal an interesting and unexpected thermal instability which allows the convenient synthesis of carboxylic acid fluorides 5b–f. This procedure offers advantages over known methods: All operations can be performed in a standard glass apparatus and do not require high pressures. The formation of RCOF 5 is assisted by the pyridine moiety of 4, which splits off and functions as a Lewis base to intercept the BF3 acid. The structural and electronic relationships as well as dominating differences between the very reactive cations of 4 and their almost "inert" uncharged precursors, the dihydropyridines 1, are discussed both on the fundament of experimental evidence (X-ray structures of 1f and the extremely reactive and very labile 4f) and theoretical investigations (ab initio and DFT MO calculations).


The paper deals with the interpretation of judicial opinions, an important theme, but practically unapproached. The existent rules in the matter and the means to perform the interpretation are also considered. Furthermore, the criteria governing the interpretation of judicial opinions will be discussed.


The main result of this paper amounts to the following statement: If a sequence of pairs of random variables $(\xi _n ,\eta _n )$ is given and this sequence converges in variation to a pair of random variables $(\xi ,\eta )$, then $\lim _{n \to \infty } I(\xi _n ,\eta _n ) = I(\xi ,\eta )(I(\xi ,\eta ){\text{ is the information of the pair }}\xi ,\eta )$ if and only if the sequence of corresponding information densities is uniformly integrable. A similar result is proved for entropies and for a new concept in information within a probability E of events. Conditions are found for the convergence of these quantities.

High blood pressure (hypertension) can be one of the most important causes of morbidity or mortality, both maternal and fetal. Monitoring the values of blood pressure during pregnancy and the impact on the health of the pregnant woman and the evolution of the pregnancy by the general practitioner is one of the main prophylactic measures. Surveillance of the pregnant woman, even from the first month of pregnancy, and the identification of risk factors for hypertension are the basis of a diagnosis and early therapeutic intervention, in order to prevent complications. The guidelines also address the intervention and postpartum counseling of these pregnant women on the risk of developing other cardiovascular complications over time, as well as the risk that the next pregnancy will have pregnancy-induced hypertension. The general practitioner, through these interventions, is an important link in the multidisciplinary monitoring team of pregnant women at risk for pregnancy-induced hypertension.


A new simple, rapid, sensitive, selective, and accurate method for the spectrophotometric determination of metoclopramide hydrochloride (MCP-HCl) in different pharmacetical preparations has been developed. Metoclopramide hydrochloride is widely used in the treatment nausea and vomiting. The spectrophotometric method is based on diazotization of primary amine group of (MCP-HCl) with sodium nitrite and hydrchloric acid followed by reaction with other drug doxycycline hyclate (DOX-HYC) as coupling agent in alkaline medium to form a stable yellow azo dye, showed amaximum absorption at 452 nm. Beers law was obyed in the concentration range of 0.1-10 μg.mL-1 with amolar absorptivity (3.81×104) L.mol-1.cm-1, and sandell's sensitivity 0.009 μg.cm-2, respectively. The analytical parameters were optimized as the fallowing: The best temperature is 1-30°C), the best time to complete reaction is 15 min and the best volume of doxycycline hyclate (DOX-HYC) solution is 1.5 mL. Limit of detection (LOD), and limit of quantification (LOQ) are 0.012 ppm, and 0.043 ppm, respectively, the recoveries range 98.58%-100.61%. The method was successfully applied to the analysis of the (MCP-HCl) in its pharmaceutical preparations (tablets, syrup, injection and orals drop).

A series of monolithic active pixel sensor prototypes (APTS chips) were manufactured in the TPSCo 65 nm CMOS imaging process in the framework of the CERN-EP R&D on monolithic sensors and the ALICE ITS3 upgrade project. Each APTS chip contains a 4 × 4 pixel matrix with fast analog outputs buffered to individual pads. To explore the process and sensor characteristics, various pixel pitches (10 µm–25 µm), geometries and reverse biasing schemes were included. Prototypes are fully functional with detailed sensor characterization ongoing. The design will be presented with some experimental results also correlating to some transistor measurements.


Objective:To observe the effects of Roxithromycin(RXM) on P27 expression and its apoptosisinducing effect in airway smooth muscle cells(AMSCs) in vitro. Methods:ASMCs from asthmatic rats cultured in vitro were exposed to RXM with different final concentrations(10,25,50 and 100μg/mL,that was group R10,group R25,group R50,group R100). Cells without RXM exposure served as the control(group R0). Cell proliferation and apoptosis were examined after the treatment of RXM for 48 h. P27 mRNA and protein expressions were measured by RT-PCR and Western Blot. Activated Caspase-3 and Caspase-9 expressions were determined by Western Blot. Results:Apoptosis rate increased in a dose-dependent manner after the treatment of RXM,while survival rate decreased. Compared with the control group(3.3±1.2)%,apoptosis rate in experimental groups [(5.8±2.2)%,(6.3±1.1)%,(14.8±8.0)%,(39.4±7.9)% respectively for group R10,group R25,group R50,group R100] were higher. P27 mRNA expression(0.31±0.05,0.35±0.07,0.38±0.06,0.47±0.05) and P27 protein expression(0.82±0.29,0.97±0.33,1.02±0.37,1.44±0.18) increased after stimulation,while the measurements in the control group were 0.27±0.05 and 0.37±0.42. Furthermore,activated Caspase-3 and Caspase-9 expressions in experimental groups were much higher than that in the control group. P27 mRNA and protein expressions had a negative correlation with survival rate(rs=0.864,P0.01; rs=0.639,P0.05),but a positive correlation with apoptosis rate(rs=0.684,P0.01; rs=0.622,P0.05). Conclusion:RXM plays a role in anti-proliferation and pro-apoptosis,by up-regulating P27 expression of ASMCs in vitro.

The study by Anderson and Zimmer [1992] of goodwill accounting policies uses a pooled time series experimental design. This approach can add substantially to our understanding of accounting policy choices, but not in the manner used by Anderson and Zimmer. Where accounting policy choices are believed to be independent from one period to the next, then a time series approach can greatly enhance our ability to capture the influence on such policy choices of changing circumstances, more so than a simple cross-sectional test. Conversely, if accounting policy choices are not independent between periods, pooling over time can overstate significance levels of statistical tests. The nature of Anderson and Zimmer's data makes the impact indeterminate. However, even under an extreme assumption, pre-regulation evidence remains significant at conventional levels.

The general setting of this paper is the metropolitan housing market of Vienna where in contrast to freemarket societies different kinds of support and control mechanism affect the market operation. For example, rents are partly controlled and new housing production, housing maintenance and modernisation are to a great extent subsidised by the federal government and the provincial governments of Vienna and Lower Austria. In this paper, a housing market simulation model is presented which attempts to lake into account the regulated and institutionalised nature of the metropolitan housing market of Vienna. Particular emphasis is placed on the demand side.


Introduction: Inflammatory bowel diseases (IBD) are chronic autoimmune diseases that require ongoing treatment and monitoring. Medical nonadherence plays a significant role in treatment failure, resulting in poor clinical outcomes including corticosteroid need, hospitalization, and surgery. Biologic therapy are administered at maintenance intervals ranging from 4 to 8 weeks. This study aims to identify risk factors for nonadherence to biologic infusion appointments in patients with IBD in the COVID-19 pandemic. Methods: This is a single-center retrospective chart review including 123 patients with IBD who received infliximab or vedolizumab at a university infusion center between January 2019 and September 2020. Beginning in March 2020, all patients with IBD receiving infusion therapy at our infusion center received a secure electronic message through the medical record portal encouraging maintenance of therapy and emphasizing the safety precautions given the pandemic. Chart review data collected for analysis included demographics, IBD disease type, socioeconomic status, employment, smoking status, poly-pharmacy, anxiety or depression diagnosis, and travel distance from home address to the infusion center. Nonadherence was classified as a categorical variable and defined as a delay from scheduled infusion by greater than 14 days. Multivariate logistic regression was performed to identify predictors of infusion nonadherence. Results: In 2019, 16 (13%) patients were noted to be nonadherent (38% female, 81% Crohn's disease) to infusion appointments. Improvement in adherence was seen in 10 (63%) of these patients in year 2020. Multivariate analysis demonstrated higher infusion frequency as an independent variable for nonadherence (OR 1.724, 95% CI 1.063 – 2.795, p , 0.05). No significant differences were noted in age, sex, marital status, distance from infusion center, smoking status, employment, year of diagnosis, infusion medication, number of overall active medications, or diagnoses of depression or anxiety between the adherent and nonadherent cohorts. Conclusion: Prior to the COVID-19 pandemic, nonadherence to infusion appointments in our IBD center was low (13%). We observed an improvement of 63% during the COVID-19 pandemic in the previously nonadherent cohort. Higher frequency of infusion appointments was independently associated with medical nonadherence. Patient education and attention to infusion frequency should remain an integral part of all IBD clinical visits to improve medical adherence.


The present article delves into the understanding of the digital gap that divides the younger age groups from those who are older, specifically the young (17‐30), adults (31‐45), mature adults (46‐60), and older adults (61‐75). The analysis carried out in three capital cities of Latin America (Buenos Aires, Lima, and Guatemala City) finds that there is a pattern of convergence in the trajectory of Internet appropriation of users belonging to different age groups. However, the gap between the younger groups and the older group does not close completely, even after several years of experience using the Internet. Likewise, it is observed that the adoption of more sophisticated activities on the Internet is conditioned by characteristics specific to each age group.

Abstract Micro-pillars forming in micro channels have been implemented by hot embossing. With dry etching and chrome photo mask, the silicon mold was fabricated using lithography process for manufacturing micro-pillars in micro channels. The hot embossing experiments are executed on the embossing machine by embossing the PMMA substrate and the silicon mold. Making the polymer filling in the concave cavity of the silicon mold is a difficulty, so the laws of polymer filling in the concave cavity were researched. The effects of three key embossing parameters including pressure, temperature and time on the PMMA replication accuracy were studied, and the optimal molding parameters were obtained. This work is instructive to fabricate microfluidic chips with micro-pillars.


Inadequate synchronisation of central government service and superannuation rules with a favourable demographic structure and social developments may adversely affect labour and effort of government employees. A slowdown in fresh recruitment has had a negative impact on the system-dependency ratio and the improvement in age-dependency has not resulted in economic benefits. Some recent decisions may exacerbate both inter- and intra-generational equity concerns in employees' compensation. These may have implications for the cost and quality of public services.


Forfeiting is a kind of nonrecoursed purchasing financial service supplied by commercial banks,which buy the exporter′s debt obligations collateralized by banks.At present,forfeiting is very popular and widely-used abroad.This kind of financial service is introduced into China in the early 1990s,which still remains the primary level and short of experience.The aim of this paper is to develop forfeiting business well by analyzing the present problems as well as the advanced foreign experience.


ObjectiveTo investigate the basal cortisol level and its circadian rhythm in a cohort of Chinese women with polycystic ovary syndrome(PCOS).MethodsA cohort of 63 PCOS women(21 obese and 42 non-obese) and 38 non-obese healthy controls were included in this study.Serum cortisol levels at 8AM and 4PM as well as the rate of loss of cortisol circadian rhythm were compared among the obese PCOS group,non-obese PCOS group and healthy controls.Possible factors associated with the basal cortisol level were analyzed.ResultsBasal cortisol level in the obese PCOS group,non-obese PCOS group and healthy controls were(325.7±125.7)nmol/L,(407.6±165.6)nmol/L and(397.4±129.9)nmol/L,respectively.Obese PCOS group had a lower basal cortisol level than the healthy controls(P0.05).The ratio of 4PM:[KG-*2]8AM cortisol was higher in the obese(0.78±0.54) and non-obese PCOS group(0.61±0.34)than the healthy controls(0.46±0.20)(P0.05).Circadian rhythm loss occurred more frequently in obese PCOS patients(47.6%) than the healthy controls(10.5%)(P0.05).Basal cortisol levels were inversely associated with BMI(P0.05).ConclusionObese PCOS patients have an activated HPA axis,with decreased basal cortisol levels and higher rates of circadian rhythm loss.BMI might play an important role in cortisol metabolism as well as the HPA activation.

Women in Pakistan are significantly contributing to national economy but their work is undervalued and they are facing a seemingly invincible array of barriers which are preventing them to become more productive and empowered citizens.  The current study aims to empirically analyze the impact of various determinants particularly human capital, social capital, awareness to labor laws and role of middleman on labor productivity of home based and outdoor women workers in Multan Division, Punjab, Pakistan using ordinary least square methodology. The results indicated that human as well as social capital has significant impact on the productivity of women. The coefficient of age, ownership of assets, family expenditures, self-employment, working as employee, worker's satisfaction, awareness about labor laws, urban location, marital status and joint family setup have a positive, while age-squared, number of children, restrictions to achieve education have a negative impact on labor productivity of women both home based and outdoor. The results provide evidence to suggest that policy makers should focus on human as well as social capital to improve women's capability to enrich their labor productivity, their living standards and growth of economy.


The increasing amount of information in diagnostic imaging demands more efficient software tools. The picture archiving and communications systems (PACS) offers solutions to adequately manage large quantities of diagnostic information. Based on the specifications of a digital imaging and communications in medicine (DICOM) 3.0 information model, we have developed a preliminary software representation. We have applied the unified software development process. This process has established phases and workflows to obtain quality characteristics, like completeness, extensibility, reusability and reliability. Also, the unified modeling language was used to represent the results. Three workflows were used to produce an architecture of the library. Our model satisfies the DICOM information model specifications.


The deposition of titanium into high aspect ratio vias and trenches is investigated using ionized physical vapor deposition (I-PVD). Sputtered titanium atoms are ionized by a high density, inductively coupled plasma of argon at 10 and 30 mTorr. The Ti+is then collimated by the plasma sheath and directionally deposited into vias and trenches ∼1 μm in width. The ability of I-PVD to deposit titanium at the bottom of narrow, deep vias and trenches is characterized by cross sectional scanning electron micrographs. The bottom coverage of 3:1 aspect ratio vias increases from 45% to 75% as the argon pressure and plasma density increase. The percentage of titanium flux that is ionized by I-PVD is extracted from analysis of bottom coverage data and falls between 50% and 85%. A method of extracting the effective transverse temperature of Ti+ is also developed. Transverse temperatures increase from 0.13 to 0.18 eV as argon pressure and radio frequency power are increased.

The tissue specific LDH isozyme pattern is examined in three species of the economically important tilapiine fishes, Oreochromis niloticus, O. aureus and Tilapia zillii, using horizontal starch gel electrophoresis. Like the majority of vertebrates, tilapiine fishes exhibited the usual relative electrophoretic mobility of the A4 and B4-that is, B4 carries a greater net negative charge. Isozyme of A4 homotetramer was predominant in the skeletal muscle, while B4 one was greatly expressed in heart muscle. Heteropolymeric isozymes of A and B composition were recognized. They were expressed in some organs and absent in others. Therefore, the present study indicated that tilapiine species could be considered 3-5 isozyme fishes. The total number of LDH isozymes of A and B composition is under genetic control of two loci, Ldh-A and Ldh-B. The LDH patterns of eye and brain displayed an additional band which was detected anodal to B4. This anodal band is designated as LDH-C4 isozyme. The latter isozyme is encoded in a third Ldh locus designated as Ldh-C. While the brain has heteropolymers of CA, CB and CAB polypeptide composition, the eye was the only organ that expressed the C4 homopolymer. The present investigation showed that C gene was able to function but at lower levels in non-neural tissues. The LDH isozyme patterns of muscle, heart and eye were also compared among the three tilapiine species. The isozymatic LDH patterns in the eye of the examined species were similar except at Ldh-C locus. The genetically controlled restriction of the heterotetramers assembly along with the homology of the three Ldh loci among species was discussed.


This paper proposes a new approach to the processing and analysis of medical images. We introduce the term and methodology of medical data understanding, as a new step in the way of starting from image processing, and followed by analysis and classification (recognition). The general view of the situation of the new technology of machine perception and image understanding in the context of the more well known and classic techniques of image processing, analysis, segmentation and classification is shown below.


Between 2007 and 2013, public procurement systems in Latin America and the Caribbean underwent a critical reform process. However, not much is known about the elements of reform and their effect on the public sector. In order to assess this gap in knowledge, this study used an institutional evaluation multivariate tool developed and carried out by the Inter-American Development Bank called PRODEV. Based on a sample panel of countries, effects on the development of public procurement systems were calculated. The results indicated that, of the three main areas of procurement reform evaluated, the creation of a procurement agency2 had the largest impact. At the same time, evidence was found that backed the hypothesis that creating these agencies had a positive effect on the perception of public sector performance.

DEA model was applied to comparatively analyze data of grain production efficiency for 14 grain producing countries( cities) of Jilin province from 2004 to 2013 with static perspective and dynamic perspective. Tobit model was used to analyze the related influencing factors. The results reveal that there are slacks in input factors in Dehui and other countries. Productivity of total factors is low in the major grain producing counties. Average grain acreage per household has significantly positive effect on production efficiency,proportion of farmers in cooperatives has positive effect too,whereas agricultural machinery power per household has a negative impact. On this basis,rational allocation of factors' input in the major grain producing counties of Jilin province was suggested,including improving service ability and level of farmer cooperatives,promoting land transfer,moderately expanding land management scale and improving utilization rate of agricultural machinery equipment.


This work outlines the role played by the Basque language in the history of Navarre. The lack of consensus that currently exists in the so-called «Foral Community» about the identity of the Navarrese and their institutional future makes the historiographical approach to this question very difficult. The history of the Old Kingdom, not to say that of its languages, perhaps more than any other history, is usually written ad probandum . In Navarre, the Basque language is manipulated by two extremes. On the one hand, Basque nationalism attributes to it an expanse of land larger than the area it has ever had in reality. On the other, Spanish Nationalism and Navarrism deny or ignore the fact that it was the language of the majority of the Navarrese until the 19 th century.


Android是当前最流行的移动设备上的智能操作系统。随着移动设备的蓬勃发展,移动端应用在人们生活中也越来越重要。但是由于开发者考虑不足或者对移动端的安全的不够重视,许多的移动应用存在安全漏洞。利用钓鱼劫持漏洞可以在用户未察觉的情况下窃取用户的重要信息,这对用户的信息安全和财产安全造成了巨大的威胁。本文通过对Android Activity组件进行研究,设计并实现了对Android应用的钓鱼劫持漏洞检测系统。利用该系统对从MM商场下载的500个常见应用进行检测,结果表明钓鱼劫持漏洞在Android应用中广泛存在。本文最后给出了针对钓鱼劫持风险可行的防范建议。 Android is the most popular mobile device's intelligent operating system. With the rapid devel-opment of mobile devices, mobile applications are becoming more and more important in people's life. However, due to the developers' inadequate consideration or attention for mobile device se-curity, a lot of applications have the security vulnerability problems. Using fishing hijacking vul-nerabilities can steal the user's important information in the case that users are unaware, which has caused a huge threat to the user's privacy and property security. In this paper, through the study of activity, we design and implement a phishing detection system of Android application. Using the system to detect the 500 common applications from the MM shopping market, the results show that the phishing hijacking vulnerabilities of Android application exist widely. At last, the paper gives the feasible preventive suggestions for the risk of the fishing.


Abstract An experimental study on the formation of hydrogen bubbles on a mill-scaled steel surface was conducted near the entrance to a crevice that simulated a disbonded pipeline coating surrounding a holiday and contained a carbonate-bicarbonate solution. The study showed that the growth rate of bubbles and their effects on the potential along the crevice are a function of the potential applied at the holiday and the crevice thickness, while the orientation of the simulated crevice and the temperature had little further effect on bubble formation. Because of IR drops along the crevice, the rate of hydrogen release is lower for creviced surfaces than for noncreviced ones exposed to the same applied potential. Thus, for both situations, the highest (least negative) potential for hydrogen release is between −1.05 and −1.1 V (SCE), when the potential is made successively more negative from about −0.8 V at daily intervals. However, when the noncreviced surfaces that had been held previously for extensive per...

Gonadotropin releasing hormone (GnRH) surge is important for the puberty onset in animals. This pulse is under the control of the neurons pre- sent in the suprachiasmatic neuclei (SCN) and Pre optic area (POA). These neuclei are expressing kisspeptin neurons in which the pulse generation is initiat- ed. However data regarding pulse generation in the kisspeptin neurons are not yet well understood. In this review it is hypothesized that the presence of cer- tain factors like NKB/dynorphin and different micro RNA are involved in the pulse generation in the kisspeptin neurons and are important for the regulation of puberty. In this review, role of these factors in the involvement of GnRH pulse generation at puberty are summarized.


Synergistic extraction of Ani(in) was studied with HTTA in combination with bifunctional (DHDECMP) and mono-functional (TBP) neutral donors in benzene medium at various fixed temperatures. The equilibrium constant (log K )̂ for the organic phase synergistic reaction with DHDECMP was found to be higher by about two Orders of magnitude as compared to that with TBP, in spite of their comparable basicities. This indicated the bi-functional behaviour of DHDECMP in contrast to the previous studies reported for Pu(VI) where DHDECMP was observed to behave as a mono-fiinctional donor. Thermodynamic Parameter viz. high + ve AS with DHDECMP compared to that with TBP supported this conclusion. However, the Ai/ values were comparable in the two cases and this was attributed to the expenditure of more energy for the release of larger number of water molecules by DHDECMP in comparison to that by TBP.

Do Austrian households adapt their savings and loan decisions in an ultra-low interest rate environment? To answer this question, we analyzed a special OeNB barometer survey conducted in spring 2015 that allows us to assess household interest rate perceptions as well as their impact on saving, portfolio allocation and borrowing decisions. Overall, we find that the very low interest rates were only one of several determinants in savings and loan decisions and have had only a small effect so far. The impact of the ultra-low interest rate environment on portfolio choice is also quite limited. Households that did adapt their portfolio often showed a stronger preference for savings with savings and loan associations than for other options. Furthermore, we observe a shift to real assets. Portfolio rebalancing into riskier assets is not widespread. Many households at the time of the survey considered circumstances relatively favorable for taking out loans. However, this does not imply that loan demand increased strongly, as borrowing decisions are also affected by other, potentially more important determinants. If they were faced with higher loan installments, most households would cut consumption expenditures. The survey results may be useful in assessing e.g. the effectiveness of monetary policy. The modest impact of ultra-low interest rates on savings and portfolio rebalancing into riskier assets suggests that ultra-low interest rates have a limited ability to stimulate aggregate demand through the risk-taking and portfolio rebalancing channels, at least in the case of households in Austria.


The purpose of this study was to determine and analyze the implementation of the model of learning to play parallel to the Islamic religion as a means of developing children's creativity. Model selection played as a variable in this study is based on the reality that life is synonymous with the world of children playing while developing creativity is needed at an early age. The study was conducted in RA Tarbiyatul Kesambi Mejobo 2014/2015 school year by using an qualitative approach.The  findings of this study indicate that through the application of models to play parallel to learning Islam can become a vehicle for the development of children's creativity in RA Tarbiyatul Kesambi Mejobo Kudus. This method also gives many conveniences for children to understand the material contained in the teaching of Islam in view of their very own interest in the instrument used games. Several factors play a role in the implementation of  this model include an atmosphere of learning, their situation that encourages responsibility and independence within the students, as well as the factors that are more personal than the child itself.


Before getting into the substance of our mission, I want to take the opportunity to talk about a closely related and also important matter: the recent activity in mergers and acquisitions. Over the last couple of years, the activity level in this area has increased, achieving great public notice and causing Congress to consider legislation to limit mergers. My object is to give you our perspective on the recent spate of activity, and particularly to correct some of the misperceptions that I think have arisen in this area. We tend to focus our attention primarily on the purely antitrust aspects, which are rarely significant because most of these transactions are conglomerations. We also perhaps take too much for granted the portrayals that we see in the popular press about what is in fact going on.


The physico-chemical properties of iron oxyhydroxide plaques formed on the roots of Phragmites australis under field and laboratory conditions were determined using electron microscopy and energy dispersive spectrometry (EDS) analysis. Plaques were present as an amorphous coating on roots with an uneven distribution. They were shown to be composed of iron in both the field and laboratory, and phosphorus was found to be adsorbed onto the surface of plaques formed in the laboratory. The uptake of copper and manganese in the presence and absence of plaque was investigated under two different pH regimes. Concentrations of Cu were lower in the shoots of P. australis in the presence of plaque (565 mg kg−1) than when it was absent (1400 mg kg−1), under growth conditions of higher pH (6.0). The adsorption of Cu and Mn onto the plaque surface was not the mechanism by which plaque reduced the uptake of other metals. Alternatively, the plaque may simply act as a physical barrier. Under conditions of lower pH (3.5) the activity of hydrogen ions at the root surface interfered with the movement of metals into the root and masked any potential effect of iron plaque.


Asthma is an inflammatory disorder of the airways associated with increased airway responsiveness and airway remodeling. Several genome wide association studies (GWAS) and non-GWAS studies have demonstrated a strong genetic linkage of chromosome 17q21 genes with asthma in populations of diverse ethnic backgrounds. In particular, SNPs in the 17q21 region are found within a large linkage disequilibrium (LD) block that contains not only the orosomucoid like-3 (ORMDL3) gene, but also includes other 17q21 genes i.e. gasdermin B (GSDMB), IKAROS family zinc finger 3 (IKZF3), and zona pellucida binding protein 2 (ZPBP2). Studies of mice expressing increased levels of the human ORMDL3 gene have demonstrated that these mice have spontaneous increased airway remodeling and airway responsiveness in the absence of airway inflammation. Further functional studies are needed to investigate whether some or all of these four genes could contribute to the pathogenesis of asthma.

To monitor the temporal and spatial characteristics of particulate matter and water vapor in the aerosol pollution and haze episodes, the polarization Raman Mie lidar system has been developed. The lidar system includes four detection channels and it can measure the extinction coefficient and depolarization ratio of particulate matter as well as water vapor mixing ratio. The extinction coefficient indicates the visibility of atmosphere and it associates with the concentration of particulate matter. The depolarization ratio demonstrates the nonsphericity of particulate matter and is useful to distinguish the dust and pollution aerosol. The water vapor mixing ratio denotes the content of water vapor in the air and it is an important factor to influence of the hygroscopic growth on the pollution aerosol. The lidar system can operate in the automatic and continuous modes through a window on the roof of the observation room regards of the weather, and it takes continuous measurement from 20 November 2013 to 6 February 2014 over Hefei, China. During the experiment, the typical results of particulate matter measured with lidar in clear air, aerosol pollution and haze, and dust episodes are analyzed and given. The lidar observations are also compared with the air quality data and the meteorological data on the ground.

In the paper [1] , we gave a new formula for the inversion of the Riesz potential operator I α ϕ = 1 γ n (α) R n ϕ(y) dy |x − y| n−α , x ∈ R n , γ n (α) being the well known normalizing constant. The following theorem was proved. Then the inversion of the Riesz potential operator f = I α ϕ, ϕ ∈ L p (R n), 1 ≤ p < n α , can be written in the form ϕ(x) = 1 γ n (−α) lim ε→0 R n 1 (|y| 2 + ε 2) n+α 2 − εA(y, ε) f (x − y)dy (1) where A(y,) = m k=1 (−1) k−1 c m,k k−1 (|y| 2 + 2) n+α 2 +k with c m,k = m k (n+1 2) k (α 2 −m+1) k. The limit in (1) exists in the usual sense, for " nice " functions f (x), and in the sense of L p-convergence or almost everywhere, if f ∈ I α (L p). In particular, in the case 0 < α < 2 the inversion of the Riesz potential operator I α ϕ may be taken in the form ϕ(x) = 1 γ n (−α) lim ε→0 R n 1 (|y| 2 + ε 2) n+α 2 − n + α α ε (|y| 2 + ε 2) n+α 2 +1 f (x − y)dy. (2) We use this opportunity to note a misprint in the formula (7.21) in [1]: the factor n+1 α there should be replaced by n+α α , as in (2). We wish to prove the following theorem. Theorem. The formula (1) is nothing else, but ϕ(x) = (−1) m γ n (2m − α) lim ε→0 R n ∆ m 1 (|y| 2 + ε 2) n+α 2 −m f (x − y)dy (3)

Cortical ensembles of neurons perform a large class of tasks which require real-time processing of complex temporal inputs. These tasks involve identifying complex structures and relationships in massive quantities of low precision, ambiguous noisy data. To get some insights into neural mechanisms responsible for the performance of these tasks in a relatively large ensemble of cortical cells, we use a natural closed-loop computational framework. By incorporating functions of readout, reward and feedback, we apply such a framework of neural ensembles to classification and recognition tasks of real-time temporal data. This approach is inspired by neurobiological findings from ex-vivo multicellular electrical recordings and injection of dopamine to the neural culture. Analysis of this functional system provides a new insight into the structure of the spatio-temporal firing patterns, coined "Cliques", that are in a way the neurophysiological carriers of higher-level task-dependent functions and perceptual elements. Such cliques are generated by neural ensembles that interface with the external environment by means of complementary networks that serve the function of readout. Cliques are thus functions of both, network's state and computational task. To observe the cliques, a readout network must be incorporated into the computational system in a closed-loop manner. The emergence of cliques is mediated by spatio-temporal dynamical liquid-currents, through a selective process of Co-Evolutionary learning of two neural ensembles. Liquid-currents from presented inputs to cliques are the dynamic realizations by means of the neural ensembles. The definition of liquid-current intensity leads to a conclusion that the emergence of cliques occurs in cortical ensembles of cells regardless of the realizations at the cellular level and of the intrinsic dimensions of the problem.


The hepatoprotective activity of Conyza bonariensis ethanol extract was studied against paracetamol induced hepatotoxicity in mice. The results showed that an extract of C.B (250 mg/kg and 500 mg/kg) produced (p<0.05) decline in paracetamol induced liver marker enzymes and total bilirubin, but its 750 mg/kg showed remarkable decline in ALT, AST, ALP and TB levels, compared to the reference levels of silymarin and results were supported by histopathology of liver section. So, it is concluded that 750 mg/kg is highly potent dose of ethanol extract of Conyza bonariensis and this potential may be due to the presence of the active constituent: qurecetin and chromatogram by HPLC confirmed its presence.

A proof-of-concept military advanced mobile generator set has been developed. The military generator set uses an internal combustion diesel engine to drive a radial-gap permanent magnet alternator at variable speed. The speed of the engine is determined from a user selectable interface that for a given load and ambient thermal conditions controls the engine to run at its most efficient operating point. The variable frequency, variable voltage produced by the permanent magnet alternator is diode-rectified to a high voltage (/spl sim/400 V) DC link, and an inverter is used to produce selectable frequency, controllable AC voltage. As part of the power electronics for this unit, a 7 kW bi-directional DC-DC converter has also been developed. The converter can charge 24 V batteries that are used to start the internal combustion engine and to power auxiliary low voltage DC loads. Additionally, the bi-directional converter can also draw power from the batteries to help maintain the high voltage DC link during severe load transients. Because of stringent weight and volume requirements for this application, the minimum in energy storage elements (high frequency transformers, capacitors, and inductors) was used. This paper presents a description and experimental analysis of this novel DC-DC converter design.


Radiation field reaching a slope surface was modeled with three additive terms: the direct solar irradiance, diffuse sky irradiance Ed, and reflected irradiance from adjacent terrain Et. Most methods of topographic effect correction of satellite imagery, however, did not treat Ed and Et properly because exact calculation would require huge computation power. In this paper, we use fast algorithms for generating horizon and viewshed to evaluate Ed and Et, respectively. To demonstrate the difference between approximate methods and the exact method, we use an actual Landsat TM image and evaluate the Ed and Et of every pixel in the image for most bands.

Recently Natural Deep Eutectic Solvents (NADES) show their potential as a promising green solvents at 21 th century for extraction of natural products. Rutin, a poorly water soluble flavonoid, was reported better solubilized in NADES than in water as well as a paclitaxel and ginkgolide B, a completely water-insoluble compound. In case of curcuminoids, phenolic compounds from powder of Curcuma Zeodaria shown better solubilized in acidic type of NADES such malic acid-sucrose-water (MAS-H 2 O = 1:1:11, mole ratio) and citric acid-sucrose-water (CAS-H 2 O = 1:2:15, mole ratio) compare to water and ethanol. Indicating that NADES, a water-based solvent, appropriate for extracting curcuminoids. However, the inherent high viscosity of NADES hamper the process extraction. Lowering the viscosity, water content of NADES is varied, adding a certain amount of water up to 60% of water content. All the varied water content of both CAS-H 2 O and MAS-H 2 O were successfully extracted curcuminoids. Yielded 0.06-0.16 mg curcuminoids/g dry weight. However, 60% of water content of both CAS-H 2 O and MAS-H 2 O gave more or less similar value of curcuminoids to CAS-H 2 O (20% of water) and MAS-H 2 O (30% of water). Curcuminoids is more stable in CAS-H 2 O compare to MAS-H 2 O for 96 h of time duration.

Abstract. In this paper, we propose a one-step iteration for the approximation of common fixed points of two uniformly continuous total asymptotically quasi-nonexpansive mappings in uniformly convex hyperbolic spaces. We establish strong convergence and Δ-convergence results of the proposed iteration in this setting. As a consequence, our convergence results improve and generalize various results announced in the current literature.


in religion. " God," he says, " is not known except by means of the reason," and he warns his readers against the pantheistic tendencies inherent in the doctrine of fand. We find frequent borrowings from the Gospel and other works of Jewish or Christian origin, but it does not follow, and personally I think it unlikely, that he had studied the earliest Arabic translations of this literature. There was a vast floating stock of such foreign goods, easily accessible to Moslems at the time. Dr. Smith's learned and lucid exposition should attract many besides specialists. On p. 71,1. 3, " group " is obviously an unsuitable word for the AM al-Sunna wa-'l-Jamd'a, who were not " founded " by any one. In the first footnote on the same page, read " Ibn Khallikan, iii, p. 554 ; Sha'rani, p. 84". The spelling of proper names is occasionally inaccurate, e.g. 'Atba ('Utba), Hudayfa (Hudhayfa), and on p. 259 Ghurriyat (Ghunyat), Ibn Rahwiya (Rahawayh), Ibn al-DakhmasI (al-Dakhmisi). But these are small blemishes in a fine book, for which every student of Sufism will be grateful.

Pearl roundness is an important index in the pearl value evaluation and classification. The existing roundness classification schemes are usually based on 2D image or mechanical methods. However, the 2D image ignores the depth or 3D information, which leads to low classification accuracy, and mechanical classification is easy to cause surface damage. An automated grading method of pearl roundness based on optical coherence tomography is proposed. Based on the high-resolution and low-cost 3D imaging of the pearl surface, through noise reduction, binarization, segmentation, 3D reconstruction, surface extraction, and the surface of pearl is fitted as sphere. A new digital rating index named global local roundness fraction is designed for roundness evaluation, based on the length of the three axes and of coordinates of the fitted sphere. Four grades of pearls were automatically classified by our method, and the results showed that the accuracy of the proposed scheme reached 95%, indicating that the proposed method can be used as an effective means of automatic classification of pearl roundness.


As the powerful landlords grew to maturity and society became unstable in the Han dynasty,the powerful landlords organized private armed forces that were made of guests,clansmen,enserfed peasants by means of patriacrchal clan system and relation of dependence.Private armed forces were applied not only to resist government and evade a tax,but also to take part in the warlords' warfare.In addition,it maintained safety and stability of feudal regime to a great extent.


During the last few years, both the theory and the practice of anti‐racism in Britain have been undergoing a reappraisal. The following symposium is offered as a contribution to these ongoing debates. It begins with an essay by Tariq Modood, one of the principal critics inside the anti‐racist camp, which is followed by responses by Michael Banton, Phil Cohen, David Gillborn and Kalbir Shukra, who are all‐for diverse reasons‐sympathetic critics of certain strands in British anti‐racism.


Development of information and communication technology (ICT) plays a crucial role in catalysing economic growth. This paper proposed a conceptual framework for ICT development and foreign direct investment inflows as driver for economic growth in China and Malaysia. Although some studies have found evidence of the positive effect on economic growth of ICT development and FDI, others have revealed the opposite outcome. Policymakers are expected to implement specific policies that enhance the penetration of ICT in countries such as providing low pricing and improving ICT infrastructure. In addition, policy makers should develop policies to strengthen the macroeconomic position that leads to a stable financial sector and the use of foreign investment.


Due to its many excellent properties, diamond is being explored as a material for MicroElectroMechanical Systems (MEMS). However, as is true in the case of silicon, a large amount of basic material characterization issues still warrant investigation. This paper presents preliminary results from charged particle irradiation of Chemical Vapor Deposited (CVD) polycrystalline diamond films. The films were simultaneously dosed to a level of 9.4 x l0(exp 13)/sq cm using 700 keV protons and 1 MeV electrons. The samples were then subject to cross-sectional nanoindention analysis and Raman spectroscopy. Polycrystalline silicon was also investigated for comparison purposes. The diamond was unaffected by the irradiation. However, the silicon did indicate a slight decrease in the Young's Modulus.

Introduction: Nutritional monitoring in palliative care is extremely important, since levels of mortality, malnutrition and unintentional weight loss occur in the majority of cancer patients. In this way, it is possible to prevent nutritional deficiencies and weight loss, which leads to a worsening nutritional status. Objective: The aim of the study was to evaluate the association between the classification of nutritional status obtained by the patient-generated subjective global assessment (PG-SGA), handgrip strength (HGS) and adductor pollicis muscle (APM) in cancer patients palliative. Method: We evaluated 70 cancer patients enrolled in the exclusive palliative care program. The PG-SGA was used to assess the nutritional status. To evaluate the association of nutritional status with other predictive measures, HGS measurements were performed with a dynamometer and APM with an adipometer. Descriptive statistics and linear regression analysis were used to evaluate the ability of these measures to predict nutritional status. Results: Of the 70 patients, aged between 31 and 101 years, in which 58.6% were male and malnutrition (B+C) was found in 87.2% (n=61) according to PG-SGA. The value of APM was altered in 72.9% (n=51) patients and 42.9% (n=30) in HGS. HGS was associated with PG-SGA (b=-0.273, p=0.04) and APM didn't (b=-0,124; p=0.546); therefore, only HGS was a good predictor of nutritional status in this study. Conclusion: It's suggested the use of HGS to evaluate nutritional status in palliative cancer patients.


Emulsifying properties of bovine serum albumin (BSA) were compared between intact BSA (molecular mass of 66 kDa) and the domain I-truncated fragment (molecular mass of 45 kDa). The particle size considerably decreased with increasing both intact BSA and the fragment concentration. The intact BSA formed a more homogeneous emulsion and smaller particle distributions than the fragment at all protein concentrations. The relative amount of protein adsorbed at an oil-water interface was much less for intact BSA than for the fragment, and the surface concentration of intact BSA per unit surface area was also much less than that of the fragment, indicating that less protein is required to form a stable film for intact BSA than for the fragment. The particle size distribution in the fragment-stabilized emulsion became more homogeneous during storage time, while that in intact BSA-stabilized BSA had no significant change. These results strongly suggested that the domain I-truncated fragment with a higher hydrophobi...


Objective To explore the therapy of acupoint application when nursing chronic bronchitis patients.Methods 150 chronic bronchitis patients in our hospital were randomly divided into two groups,50 cases in the control group and 100 cases in the observation group.The control group received routine nursing while the observation group adopted routine nursing with acupoint application.The improvement of two groups in terms of cough,phlegm,asthma symptoms after treatment and the satisfaction of patients as well were compared to evaluate the therapeutic effect.Results The total effective rate of the observation group was 91%(91/100) while the rate of the control group was 76%(38/50).The total effective rates of the two groups were compared(P0.05) and the difference was statistically significant.The total satisfaction rate of the observation group was 88%,and the rate of the control group was 56%.There were statistically significant differences in results(P0.05).Conclusion Nursing combined with acupoint sticking therapy in treating chronic bronchitis improves cough,phlegm,asthma symptoms effectively and its curative effect is better with high satisfaction of patients.


During the occurrence of the Covid-19 pandemic, the laws made by the House of Representatives of the Republic of Indonesia (DPR) as a legislative body, ideally, should not cease to reflect society's needs pursuant to the realisation of the representation principle. In analysing the fulfilment of such an ideal conception with the reality of its implementation, this paper aims to discuss the trends and discourses regarding the laws made by DPR, as a balancing power to the presidential body, during the pandemic as a new state of emergency. The authors would like to scrutinise the trend of laws passed by the DPR in various sectors, both quantitatively by evaluating the number of outcomes and qualitatively by observing the issues raised during the law-making process. Finally, this paper finds that the DPR still falls short of expectations on ensuring the actualisation of a democratic law-making process amidst the pandemic.

This paper studies the stabilization control problem for an underactuated unmanned surface vehicle (USV) using only two independent propellers. Firstly, it transforms the whole dynamical system of unmanned surface vehicles into a cascade nonlinear system based on global diffeomorphism change of coordinate, and the stabilization problem of original system can be reduced to the stabilization control problem of a resulting cascade subsystem. Secondly, design respectively time-varying smooth full state feedback law via state-feedback and observer approach. Then, we demonstrate that the original system state is globally asymptotically stabilized to the desired configuration with the feedback control law. Lastly, the effectiveness of the proposed method is illustrated and validated by simulation results on a model ship.


Tuberculosis (TB) remains a major cause of morbidity and mortality globally. Although TB most commonly affects the lungs, any organ or tissue can be involved. Extra-pulmonary forms of TB are commonly unrecognized or late diagnosed. Chylous effusion, i.e. chylothorax and chylous ascites, which is characterized by the presence of chyle in the pleural and peritoneal cavities, is an uncommon manifestation of extra-pulmonary TB. A 22-year-old male, referred to Dr. Soetomo Hospital with complaints of dyspnea, fever, and abdominal distension. Chest X-ray showed pleural effusion. Analysis of fluid obtained from thoracentesis and paracentesis showed chylothorax and chylous ascites. M. tuberculosis had been found in sputum smear examination. ADA (adenosine deaminase) test was performed on ascites fluid and a positive result was obtained. Chylous effusion in this patient were concluded to be related to TB. Patient was then treated with anti-TB drugs and somatostatin. Chylothorax and chylous ascites improved after treatment with somatostatin for 1 week. Administration of anti-TB drugs was planned to be continued for 9 months. The most common causes of non-traumatic chylous effusion in developing countries are infection of TB and filariasis. Chylous effusion is caused by obstruction or disruption of the lymphatic system. ADA test is a new biomedical method that begins to expand its use in body fluids to diagnose extra-pulmonary TB. Fasting, together with total parenteral nutrition, can decrease the lymph flow and balance metabolic impairment. Somatostatin has been used in the treatment of chylous effusion as it diminishes peristalsis and intestinal absorption of fats as well as decreases portal pressure.


The United States has exhibited two potentially connected trends – increasing individualism and increasing interest in libertarian ideology.  Previous research on libertarian ideology found higher levels of individualism among libertarians, and cross-cultural research has tied greater individualism to making dispositional attributions and lower altruistic tendencies.  Given this, we expected to observe positive correlations between the following variables in the present research: individualism and endorsement of libertarianism, individualism and dispositional attributions, and endorsement of libertarianism and dispositional attributions.  We also expected to observe negative correlations between libertarianism and altruism, dispositional attributions and altruism, and individualism and altruism. Survey results from 252 participants confirmed a positive correlation between individualism and libertarianism, a marginally significant positive correlation between libertarianism and dispositional attributions, and a negative correlation between individualism and altruism.  These results confirm the connection between libertarianism and individualism observed in previous research and present several intriguing questions for future research on libertarian ideology.

Traditionally all mobile radios and mobile phones have used one antenna common for both transmitting and receiving. For an external whip or stubby antenna this seems like the only practical solution but with the increasing use of internal antennas the number of antenna elements is not necessarily limited to one but rather the total size. On the contrary, it is shown that a number of advantages can be gained by a division of the antenna system into at least two antenna functions for transmitting and receiving. A typical advantage is that the transmitting and receiving function can be optimized separately. Diversity and other additional functions may make even more than two antennas worth considering. For 3G systems with high speed down-link requirements good antenna performance including the diversity function is an important means of enhancing the receiving capacity.


Abstract A new modified technique for collecting house dust mites is described. This technique was found to be better than other techniques described before.


A new process is proposed that converts complex feeds containing fissile materials into a chemical form that allows the use of existing technologies (such as PUREX and ion exchange) to recover the fissile materials and convert the resultant wastes to glass. Potential feed materials include (1) plutonium scrap and residue, (2) miscellaneous spent nuclear fuel, and (3) uranium fissile wastes. The initial feed materials may contain mixtures of metals, ceramics, amorphous solids, halides, and organics. 14 refs., 4 figs.


The kite thread disturbance is one of the major disturbances on the high voltage transmission line in countries, such as Indonesia, where kite-playing is a cultural activity. The kite thread destructive disturbance has a low probability. However, the impact of the disturbance can lead to a blackout in the huge area. Therefore, the kite thread disturbance can be defined as a resilience problem of a man-made attack. The lost cost of energy not served (ENSd) during every disturbance event can be defined as the cost of resilience. In the proposed assessment method, the power system modelling, and simulation are carried out to determine the impact of the disturbance to the grid as basic to calculate the energy not served. Any mitigation cost should be lower than the resilience cost.


Objective To analyze the causes of extubation failure in elderly AECOPD patients receiving mechanical ventilation and increase the rate of extubation success by drawing from previous lessons. Methods A retrospective study was conducted on 12 cases of elderly patients with AECOPD and respiratory failure who received invasive mechanical ventilation and underwent extubation failure following a successful spontaneous breathing trial. The cases were collected from General Hospital of Datong Minal Group Company between January and December in 2014. The causes of extubation failure were investigated.Results The cause of 7 cases was respiratory system dysfunction, among which 4 cases were due to the impotence of expectoration and 2 cases were due to the excessive burden of respiratory muscle,with re- intubation made within 24 hours after extubation; one case was induced by central airway obstruction,with re- intubation made within 30 minutes after extubation.Two cases were induced by the dysfunction of cardiovascular system,and the specific cause was left ventricular dysfunction,with re- intubation made between 24 and 72 hours after extubation. Two cases were induced by malnutrition,with re- intubation made between 48 and 72 hours after exturbaton. One case was induced by the dysfunction in central nervous system, with cerebral infarction diagnosed by craniocerebral CT at 48 hours after extubation. Conclusion SBT has limitation in guiding extubation. The causes of extubation failure should be noted for pertinent precautions,in order to decrease the re- intubation rate in patients with AECOPD.


A novel, efficient and facile protocol for the synthesis of a series of [Ru(NHC)(CO3)(p-cymene)] complexes is reported. This family of Ru-NHC complexes was obtained from imidazol(in)ium tetrafluoroborate or imidazolium hydrogen carbonate salts in moderate to excellent yields, employing sustainable weak base. The ruthenium complexes were successfully utilized in the transfer hydrogenation of ketones as highly active multifunctional catalysts.


The optical properties and magneto-optical (MO) activity in a bilayer nanostructure consisting of a ferromagnetic dielectric film and a noble metal film perforated with circle annular arrays are investigated. Enhanced Faraday rotation peaks with opposite signs are found. Meanwhile, enhanced polar Kerr rotation with large reflectance is also obtained at the same wavelength. The peak positions of the MO rotations accompanied by large transmittance and reflectance can be efficiently tailored by changing the geometrical parameters and the filling medium. These findings are important for applications in highly integrated optoelectronics and multiple channel magneto-optical devices.


Zaharia, Noni. Purchase Behaviors in a Cross-National Analysis of Sponsorship Effectiveness. Published Doctor of Philosophy dissertation, University of Northern Colorado, May 2015. Previous sport studies are limited to investigating consumer purchase intentions or past purchases, and not examining actual purchase behaviors. However, several researchers have acknowledged that based on the lack of actual behavior data, their conclusions are incomplete. Thus, adding behavioral information to consumer behavior research is paramount for a correct understanding of the link between intentions and behaviors. Moreover, despite the increasing number of studies measuring sponsorship outcomes in different sport settings, a major gap exists in the understanding of how sponsorship outcomes function at a global level. Thus, in order to have a more complete understanding of sponsorship and further improve consumer research, the reliability of sponsorship studies developed in one country should be assessed in other countries as well. This study served two purposes: (1) to develop a conceptual model for sport sponsorship outcomes in the United States (i.e., sponsorship awareness, sponsorship fit, attitude toward the sponsor, purchase intentions, past purchase behaviors, and actual purchase behaviors) and (2) to empirically test a sport sponsorship model (i.e., attitude toward the sponsor, purchase intentions, past purchase behaviors, and actual purchase behaviors) at a global level. The research initiatives were addressed by collecting data via


The aim of this study was to investigate the effects of different oils on growth performance of juvenile Anguilla marmorata. Five isonitrogenous and isoenergetic experimental diets were formulated to contain fish oil (FO), sunflower oil (SFO), peanut oil (PO), corn oil (CO) and soybean oil (SBO), respectively, as lipid sources each at an inclusion level of 50 g/kg. The diets were fed to apparent satiation for 10 weeks, twice a day to triplicate tanks of 30 fish each with an initial body weight 6.00±0.06 g. Weight gain (WG) and specific growth rate (SGR) of fish fed the FO and SBO diets were markedly higher than those fed the CO diet, while no other difference in WG and SGR were observed among other treatments. Fish fed FO and SBO diets had better feed utilization than the other diet fish groups. Muscle of fish fed the FO diet had significantly higher levels of C20:5n-3 and n-3/n-6 ratio compared with fish fed vegetable oil (VO) diets, while muscle n-6 PUFA and C18:2n-6 content showed an opposite trend. The present results suggest that soybean oil is a suitable replacement for fish oil for Anguilla marmorata.

Mining of ore body in the vicinity of a shaft has a significant influence on its stability. The in situ monitoring and numerical simulation are employed to analyze the effect of shaft pillar extraction at Xincheng Gold Mine. The XI# ore body is recently found around and beneath the shaft, and mining in this area may be detrimental to the shaft. Firstly, on the base of geological survey and in situ displacement monitoring, mechanical parameters of rock mass are obtained and the displacement around the shaft is measured. Secondly, the sensitivities of five main factors that may affect the shaft displacement are analyzed by means of orthogonal experiment according to the numerical simulation with . Finally, a numerical model is established according to the in situ condition; in order to forecast the shaft displacement induced by mining activities of XI# orebody, the Mining Priority Index (MPI) is put forward and used to select the optimal mining sequence. Based on the comparison between the numerical results with the monitoring data, it is determined that the ore within 100 m from the shaft is not suggested to be extracted until the last period of the shaft life.


In view of the standard correspondence between transitive groups and certain graphs, this result can be rephrased in the following manner. Let F be a graph which is connected and not complete. Assume that G « Aut F is transitive both on ordered adjacent and non-adjacent pairs of points, and that two non-adjacent points are adjacent to exactly one point. Then T has no triangles, and G and T are as on p. 151 of [9]. The proof is primarily geometric and combinatorial, groups entering only after extremely strong information has been obtained concerning involutions. The underlying geometric objects associated with such groups are defined and generalized in § 3. When all lines have just two points, these are precisely Moore graphs [12]; this suggests calling them Moore geometries in the general case. They fall into two classes, one of which has been studied in [3] using elementary arithmetic and standard eigenvalue conditions (cf. (3.3)). Elementary properties of Moore geometries are proved in § 3. In particular, it is shown in (3.6) that from any finite affine plane one can obtain in a natural manner a Moore geometry having special numerical properties; thus, in some sense Moore geometries may be regarded as generalizations of affine planes. By combining G. Higman's character theoretic result (2.1) with intricate counting arguments, in § 4 we obtain severe restrictions on involutions of Moore geometries. These are used in §§ 5 and 6 to prove (1.1); some aspects of the proof are reminiscent of arguments used for projective planes (especially (4.8)). I am grateful to G. Higman for pointing out (2.1) (in a slightly different form); this produced a considerable simplification of my original proof of (1.1). The reader strictly interested in (1.1) need only examine (2.1), (3.1H3.3), (4.1M4.8), (5.1H5.3), and §6. On the other hand, Moore


Phylogeographic and feeding ecological studies of seven terrestrial mustelid species (Carnivora, Mustelidae), the Japanese marten Martes melampus, the sable Martes zibellina, the Japanese badger Meles anakuma, the ermine or the stoat Mustela erminea, the Japanese weasel Mustela itatsi, the least weasel Mustela nivalis, and the Siberian weasel Mustela sibirica, representing four biogeographic patterns in the Japanese archipelagos (Hokkaido, Honshu-Shikoku-Kyushu, Tsushima, and Hokkaido-Honshu), were reviewed in order to clarify causes for the faunal assemblage processes of those mustelid species in Japan. Here, three main constraints were extracted as important factors on the mustelid assemblage. First, fundamental evolutionary differences maintained by niche conservatism in each ecologically diversified lineage ("evolutionary constraint") would enable the species to co-occur without any major problem (coexistence among Martes, Meles, and Mustela species). Second, "ecological constraints" would force two closely related species to be allopatric by competitive exclusion (Mu. itatsi and Mu. sibirica) or to be sympatric by resource partitions (Mu. erminea and Mu. nivalis). Third and most importantly, "geological constraints" would allow specific species to be embraced by a particular geographic region, primarily deciding which species co-occurs. The allopatric distribution of two Martes species in Japan would have been established by the strong effect of the geological separation in Tsugaru Strait. Elucidating both phylogeny and ecology of co-existing species in a community assemblage is important to know which species possess distinct lineage and which ecological traits are adapted to local environments, fulfilling the requirement of the field of conservation biology that endemism and adaptation should both be considered. The Japanese archipelagos would, therefore, provide valuable insight into the conservation for small carnivoran species.
