The premature failure of wind turbine gearbox bearings significantly affects the reliability of wind turbine operation and energy production. Damage initiated from non-metallic inclusions known as White Etching Cracks (WECs) has been identified as the dominant initiation mechanism that causes the premature failure under the influence of transient events. In this study, the factors affecting the initiation of subsurface damage from non-metallic inclusions were investigated by finite element modelling. It was found that the direction of surface traction and loading-unloading cycle had a detrimental effect on stress concentration at the tips of the de-bonded non-metallic inclusions in bearing steel.


High-precision inductorless variable equalizers with wide variable range are developed. These are attained by an extension of the Bode-type variable transfer function to higher order functions. Inductorless realization problems for these variable equalizers may have many solutions. Two simple solutions are investigated. A practical example demonstrates an inductorless variable equalizers with a \pm 20-dB variable range, in which approximation errors in decibels are reduced by a factor of more than 20 as compared with conventional variable equalizers.


In this paper,a method of test pattern generation is proposed.This method can use the functional verification programs efficiently,select the useful information for testing from the functional verification procedures,and transform them into test patterns to complete the basic fault coverage.And at the same time,the testing structure is fully made use of to perfect the test patterns and improve the fault coverage.


Abstract 4838 BACKGROUND: The aim of this study was to determine the safety, tolerance and efficacy of linezolid for the treatment of infections from Gram-positive bacteria in immunocompromised patients with Hematological Malignancy. METHODS: This was a prospective non-comparative unblinded and multi-center study in the Hematology Unit over a one-year period, administering combined use of linezolid in patients with Hematological Malignancy. RESULTS: Fifth-four adult patients received linezolid (600 mg, iv, q12h per day). Thirty-four children received linezolid (30 mg/kgr: 3 i.v. per day).Mean duration of linezolid administration was 12.8 days (range, 10–23days). Among the evaluable patients, fifty four were adults, the median age was 67(range, 30–101years); thirty four were children (range, 11 months-12.6 years), while the median age was 6 years. Primary diagnosis was acute lymphoblastic leukemia (forty-five patients), lymphoma (twenty-three patients), multiple myeloma (eleven patients), Aplastic anemia(four patients), myelodysplasia syndrome(one patients), leucopenia and hemophagocytic syndrome (two patient each). All patients were immunocompromised, 90% of them in the midst of chemotherapy cycles. The mean base number of platelet was 41×109/L(range, 30 – 138×109/L), platelet count less than 30×109/L patients were 28 cases (33%), among them, less than 10×109/L were 13 cases (14.8%). 27 out of 88 patients had positive blood cultures, methicillin-resistant Staphylococcus aureus, eighteen patients; Enterococcus, seven patients; Methicillin Resistant Staphylococcus Epidermidis and hemolytic streptococcus (one patient each).All patients were considered clinically cured after the end of the linezolid regimen (100% efficacy). The main adverse events were thrombocytopenia. There were 11 cases happened transient thrombocytopenia, Among them, four cases were happened within 4 days, seven cases happened four to seven days after received linezolid. Eliminate the possibility caused by reasons such as severe infection which can also result in thrombocytopenia, Linezolid related thrombocytopenia were only two cases (2.3%). Chemotherapy-induced myelotoxicity (90% patients) was not worsened during linezolid therapy. The platelet recovery time was also not lengthened during linezolid therapy. No bleeding episodes were presented, no Self-limited diarrhea were happened. The total adverse event rate was 2.3%; however, there was no premature cessation of linezolid in any patient. CONCLUSIONS: Linezolid may be another effective and safe therapy to treat infections from resistant Gram-positive bacteria in immunocompromised patients, even in children.

We consider the fundamental problem of inferring the distribution $F^*_X$ of a real-valued random variable $X$ and a population parameter $q^*=q[F^*_X]$ from a set of independent observations $\{x_i\}_{i=1}^N$. Inferences about possible generating distributions $F_X$ and values of the population parameter $q[F_X]$ are made without any assumptions other than the bounding interval $I \in \mathbb{R}$. The resulting nonparametric Bayesian method results in a probability distribution on the space of imprecise distribution functions on $I$. The resulting method has a natural interpretation in terms of the intervals between ordered observations, where the probabiliy mass associated with each interval is uniformly distributed on the space of possible values, but there are no restrictions on the distribution of probability mass within each interval. This formulation gives rise to a straightforward resampling method: Bayesian interval sampling. This robust method is applied to a sample data set, and examples of resulting estimators for various population parameters are given. The method is compared to common alternatives and is shown to satisfy strict error bounds even for small data sets and ill-behaved distributions.


In order to study the deformation characteristics of roadbed filling of soft metamorphic rock before and after soaking in Qinling—Bashan mountainous region,the conventional compression tests and other compression tests under cyclic loading and different soaking loadings on three different lithological roadbed fillings of soft metamorphic rocks are conducted by using large-scale compression apparatus. The research results show that both the water infiltration and the applied cyclic loading can increase the deformation of soft rock filling;and the deformation of different lithological soft metamorphic rock filling induced by water infiltration and cyclic loading is different. Moreover,the wetting deformation increases and the total compression deformation of roadbed filling decreases with the soaking load. By comparing the results of conventional compression tests with those of compression tests under cyclic loading,it is found that cyclic load increases the deformation of soft metamorphic rock roadbed filling. Therefore,the analysis indicates that the roadbed soaking and traffic loading are the two important factors affecting the deformation of soft metamorphic rock roadbed,which cannot be ignored. The above conclusions have certain guide significance for the highway construction of Qinling—Bashan mountainous region,where the soft metamorphic rock is used as roadbed filling.


The technology of virus-free culture in Rehmannia glutinosa f.hueichingensis(Chan et Sehih) Hsiao has been studied.The results show that the highest plant regeneration rate is in 6-BA 0.5mg·L-1 and KT 0.5 mg·L-1,which could achieve 75% and the fequency of induced callus was 20%;Both the virus-free percentage and the plant regeneration rate are better when the size of shoot tip is 0.2~0.5 mm;With shoot tip culture twice and heat treatment the highest virus-free percentage of 96%~100% could be obtained.


Buprenorphine is a potent analgesic with an attractive side effect profile. Although it is considered a partial mu opioid receptor (MOR) agonist and a weak partial agonist or antagonist at kappa opioid receptors, it also competes MOR exon 11‐associated IBNtxA binding with high affinity. We therefore sought to examine the roles of exon 11‐ and exon 1‐associated MOR splice variants in buprenorphine analgesia. Exon 11 knockout animals showed a profound loss of analgesia in the tail flick assay at doses over 300 times the analgesic ED50 in wildtype C57 controls, despite the fact that these animals have intact full length MOR‐1 receptors and other opioids such as morphine and methadone retain full analgesic efficacy. Furthermore, administration of a high dose of buprenorphine actually reversed morphine analgesia in these animals. In exon 1 or triple opioid knockout (MOR exon 1, DOR, and KOR) animals, analgesia was also significantly reduced relative to wildtype controls, suggesting that full buprenorphine analgesic efficacy requires both exon 11‐ and exon 1‐associated MOR splice variants, and that the pharmacology of buprenorphine is more complicated than previously believed.


An ad-hoc network is a temporary infrastructure less network which is a collection of mobile nodes in the dynamically form. This network is always independent and a isolated network. Due to the limitation power and mobility there is less sufficiency among them. In these wireless networks, the main things like confidentiality, availability authentication, anonymity, integrity to all the users of mobile communication. There are many security attacks in MANET in which these are responsible for the failure in communication from source to destination. Among such attacks black hole attack is one of such serious attacks in MANET. In this paper, we compared the existing solutions and discussed different methods to eliminate the black hole attack in MANET.


BACKGROUND
Since its introduction 10 years ago by Caprioli and associates, MALDI mass spectrometry imaging has enabled spatial analysis of drugs, lipids, peptides, and polypeptides. In polypeptides, the detectable mass range is limited to small proteins with a mass less than 25 kDa. This is a limitation, as many proteins, including cytokines, growth factors, enzymes, and receptors have molecular weights, exceeding 25 kDa. In the present work, we report the development of a novel strategy to observe higher mass proteins up to 30 kDa.

MATERIAL/METHODS
We investigated the development of sample preparation methods based on hexafluoroisopropanol (1,1,1,3,3,3-hexaluoro-2-propanol) and 2,2,2-trifluoroethanol solvents for protein solubilization optimized for high-mass proteins.

RESULTS
We were, for the first time in mass spectrometry imaging, able to detect to proteins up to 70 kDa directly from tissue. These developments indicate future avenues by which the sensitivity of protein mass spectrometry imaging can be further improved. We applied these developments to ovarian cancer and demonstrate that protein are similar to that which can be obtained using 2D gel based analyses.

CONCLUSIONS
Increasing the possibility of detecting proteins and high-mass proteins is key for developing direct tissue proteomics and especially any potential functional investigation. These data will open the door of a novel step in mass spectrometry imaging.


This study was conducted to investigate the leaf growth and flowering characteristics of 85 Hosta cultivars. The 85 cultivars were grown in a pot in Useful Plant Resources Center in Yangpyeong, Korea. H. 'Abiqua Blue Crinkles', H. 'Abiqua Drinking Gourd', H. 'Dancing in the Rain', H. 'Elegance', H. 'Inniswood', and H. 'Venus' were classified as a large size group (> 50 cm), while 27 cultivars including H. 'Abby', H. 'Birchwood Parky's Gold', H. 'Blue Cadet', and H. 'Blue Edge' were classified as a small size group (< 20 cm). The others were classified as a medium size groups. 79% of Hosta cultivars had leaf variegation. Leaf variegation type was divided into 5 types (standard, marginata, mediovarigata, albomaculata, striata). Among them 31 cultivars including H. 'Abby', H. 'Abiqua Moonbeam', and H. 'Atlantis' has a variegation type of marginata in the leaf. 36 cultivars including H. 'Abby', H. 'Abiqua Drinking Gourd', and H.'Abiqua Moonbeam' bloomed in late May and 9 cultivars including H. 'Black Hills', H. 'Boeun', and H. 'Fragrant Bouquet' started to flower on late August. Most flowers were below 3.0 cm in length, while H. 'Avocado' was longest on 10.0 cm. Most flowers have a lavender color group (63.5%), and 14 cultivars of Hosta showed white color group (16.5%). 12 cultivars including H. 'Blue Mouse Ears', H. 'Captain Kirk', and H. 'Fragrant Bouquet' had the fragrance in their flowers. H. 'Cherry Berry' and H. 'Revolution' had a colorful stalk, red and yellow, respectively.


The purpose of the study was to determine the influence of the steam explosion process on the change in properties of the material subjected to this process. Wood chips were used before and after the steam explosion (SE), and pellets made from wood chips subjected to steam explosions (black pellet). The scope of the study included determination of physical and chemical characteristics such as moisture content, combustion heat and calorific value, determination of lignin and hemicellulose,  cellulose and hydrogen, carbon, nitrogen and sulfur content. hemicellulose compounds. After the process biomass, there are still mainly cellulose and lignin compounds that are readily biodegradable. The process results in a slight increase in material humidity and lower calorific value, but further processing in the form of agglomeration results in reversal of these effects.

Abstract : The USSR State Board has approved the KS-3563 crane and has recommended it for production. The mobile part of the crane is the chassis of a KrAZ-255B truck, with good cross-country ability, maneuverability, and high traveling speed, which the crane retains. The hydraulic drive is that of a KS-3562A crane with some modifications, which has proven to be reliable, with smooth control of the operational movements. The use of hydropowered extendable supports and hydroblocking of the rear suspension has simplified the mounting and dismounting of the crane.


Polyamidoamine dendrimers were grafted onto macro-porous silica gel through solid phase synthesis methodology,and the peripheral amino groups on these dendrimers were modified by 4-hydroxybenzaldehyde,2,4-dihydroxybenzaldehyde and salicylaldehyde to obtain ligands,and then the product reacted with SnCl2·2H2O to obtain silica supported dendritic Sn complexes.The catalytic performance of the silica supported dendritic Sn complexes was investigated by Baeyer-Villiger oxidation of cyclic and acyclic ketones to obtain their corresponding lactones or esters with 30% hydrogen peroxide.It was shown that all the complexes exhibit promising catalytic activity for the oxidation of ketones(2-andamantanone,cyclohexanone,cyclopentanone,4-methylcyclohexanone,4-tertbutylcyclohexanone,3-methyl-2-pentanone and 4-methyl-2-pentanone).Under the mild condition,all the oxidations gave high conversion(75%-99%) and selectivity(95%-100%) of lactones or esters.The effects of the supporter(chloromethyl polystyrene,cellulose,chitosan,silica) and ligand on the catalytic activity were also studied;it was discovered that both the supporter and the ligand played a vital role in metal loadings and the catalytic activity of the complexes.Silica was the best supporter and salicylaldehyde was the best ligand.


A typical direct digital control (DDC) system was established and tested in two electromagnetic pulse (EMP) simulators. The interference thresholds of the DDC system under different test conditions were obtained. It is shown that the major interference path is the communication cable, and the interference introduced by the power line of the controlled equipment can also be coupled to the communication cable and then interfere with the DDC system. The protection approaches are discussed based on these experiment results.


Sorafenib tosylate (SORt) as an oral multi-kinase inhibitor is used for the treatment of advanced renal cell, liver and thyroid cancers. This drug was synthesized in this work, and its antiproliferative activities against HCT116 and CT26 cells were assessed. Afterward, the interaction of SORt with β-lactoglobulin (BLG) was studied using different fluorescence techniques, circular-dichroism (CD), zeta potential measurements and docking simulation. The results of IR, Mass, H NMR, and C NMR spectra exhibited that the drug was produced with a high quality, purity and efficiency. SORt showed potent cytotoxicity against HCT116 and CT26 cells with IC50 = 8.12 and 5.42 μM, respectively. Concerning the BLG binding of SORt; the results showed that a static quenching mechanism is the cause of high affinity for drug-protein interaction. Three-dimensional fluorescence and synchronous spectra proposed that SORt conformation has been changed at different levels, as well as circular dichroism suggested the amount of α-helix remains almost constant in the BLG-SORt complex, whereas those of random coil were decreased. The Zeta-potential values of BLG were more positive after binding with SORt, which is due to the existence of electrostatic interactions between BLG and SORt. Furthermore, thermodynamic parameters confirmed the van der Waals and hydrogen bond interactions in the complex formation. Finally, Molecular modeling showed the presence of hydrogen bond and electrostatic force in the BLG-SORt system, which was consistent with the experimental results.


In this study, orthogonal frequency division multiple access (OFDMA) based primary and secondary usage in a cognitive radio system is considered and conventional power spectral density (PSD) based technique is used to detect the opportunities in the spectrum. Primary user employs block-based or scattered subcarrier allocation scheme and the overlay system aims to utilize the spectral gaps. Comparison of the allocation schemes and effect of windowing are presented in terms of true detection and false alarm rates. It is observed that when block-based allocation is employed, the unlicensed user will be able to detect more opportunities in the spectrum compared to the case in which the scattered allocation is employed. Simulation results show that threshold selection is crucial since it is the main factor in determining the false alarm and true detection rates. It has been shown that, for either of the schemes all possible spectral gaps cannot be found when PSD is used. Questioning the suitability of PSD method results in that a new definition of opportunity is needed, forming a basis for the second part of this study.

This article describes the characteristics of an activity designed from the perspective of
connectionism and its effectiveness to develop children's mathematical thinking at the
earliest ages. From this perspective, a linear development of contents is substituted by a
global development, so that in the same activity several concepts appear at once. For the
analysis, a teaching practice carried out with 23 students of three years is presented. The
analysis allowed to observe the presence of conceptual connections (between concepts),
practical connections (with daily life) and teaching connections (with other disciplines).
We conclude that the teaching and learning of mathematics in early childhood education
from the perspective of connectionism contributes to deeper understanding of knowledge.


We tested the hypothesis that testosterone (T) treatment affords protection against ischemia/reperfusion (I/R) injury. Orchiectomized (ORX) F344 male rats received 1.0 mg T/day for 21 days or exercise training (EX) for 10 days. Treatment groups were: Sham‐operated, ORX, ORX+T and ORX+EX. At sacrifice, cardiac performance was assessed in a working heart model of I/R (25 minutes of global ischemia and 45 minutes of reperfusion). T increased recovery of aortic flow by 2.2‐fold (p < 0.05) and cardiac work by 2.0‐fold (p < 0.05). ORX reduced recovery of left ventricular developed pressure (LVDP) by 42% (p < 0.05). T increased recovery of LVDP by 2.8‐fold and cardiac contractility (+dP/dt) by 45% (p < 0.05). ORX caused a 2.6‐fold increase in pre‐ischemic cardiac release of lactate dehydrogenase (LDH), an effect that was prevented by T (p < 0.05), but not EX. T reduced post‐ischemic release of LDH release by 45% (p < 0.05). EX caused a 13% increase in cardiac expression of MnSOD and T caused a 28% increase in catalase expression. Glutathione peroxidase (GPX) was not affected by either intervention. ORX reduced serum T by ~98% and T administration elevated T 4.6‐fold over Sham (p < 0.05). Serum estrogen was undetectable in all groups. We conclude that that loss of natural T predisposes the heart to increased contractile dysfunction during I/R, and that high‐dose T confers cardioprotection through yet to be identified mechanism(s).


low or increased soil moisture. We measured the radiocarbon (D 14 C) and stable isotope (d 13 C) signature of CO2 respired from organic soils from six black spruce forests (0 to 150 years since fire). We identified major C substrates contributing to decomposition by comparing D 14 Co f CO2 to D 14 C of roots, mosses, needles, and wood separated from bulk SOM. The D 14 C signatures of these components allow an estimation of their turnover times, further constraining their relative contribution to respiration. Fastest turnover rates were observed for herbaceous litter and needles (annual to decadal) for mosses, with intermediate turnover times for roots. Dominant microbial C sources in 5 to 40 year old stands were fire remnants and litter of early succession species, while substrates with longer turnover times accounted for a larger proportion of CO2 in mature stands. At both low and increased moisture levels, the increase in CO2 efflux at higher temperatures was accompanied by a decline in d 13 CO2, but no shift in D 14 CO2. This suggests that temperature sensitivity is not greater for recalcitrant C and that changes in d 13 C likely reflect temperature dependence of microbial fractionation


Commentators today suggest that the Establishment Clause forbids religious exemptions when they could lead to harm to third parties. But the public contemporaneous understanding of the Establishment Clause allowed for such religious exemptions, and the Supreme Court has never adopted such a prohibition. This article demonstrates each of these errors, which in combination reveal that the proposed "third-party harm rule" is just legalistic advocacy—in other words, wishful thinking.


Organic Syntheses via Transition Metal Complexes, 61[1]. – Pyridines and Pyridinium Salts from (β-Aminovinyl)carbene Complexes (MCr, W) and Alkynes via 4(1H)-Pyridinylidene Complexes

Pyridines and pyridinium salts were obtained in good yields by the condensation of (β-aminovinyl)carbene complexes with alkynes. The reaction of [(Z)-β-(monoalkylamino)vinyl]carbene complexes [ 4-(monoalkylamino)-1–metalla–1,3–dienes)] LnMC(OEt)CHCRNHR1 (Z)-6a–f (R, R1Ph, Me, iPr, nBu, CH2Ph, CH2OMe) with alkynes R2CCH 7a–c (R2 nBu, Ph, CH2OMe) involves the highly regioselective formation of 4(1H)-pyridinylidene complexes . Protonation of 8 with HBF4 leads to pyridinium salts 13 by the regiospecific substitution of the metal moiety LnM by a proton. The reaction may conveniently be performed in a one–pot procedure. {[(Z)-β-(H2-Amino)vinyl]carbene}chromium complexes, e.g. 14, react with alkynes to give pyridines, e.g. 15. The thermal decomposition of 6 yields enol ethers 11. A regiospecific formation of (E)-11 is observed in the thermolysis of 6 in the presence of pyridine.


BACKGROUND
Purslane seed oil, as a potential nutritious source of omega-3 fatty acid, is susceptible to oxidation. Encapsulation in yeast cells is a possible approach for overcoming this problem. In the present study, purslane seed oil was encapsulated in non-plasmolysed, plasmolysed and plasmolysed carboxy methyl cellulose (CMC)-coated Saccharomyces cerevisiae cells and measurements of oil loading capacity (LC), encapsulation efficiency (EE), oxidative stability and the fatty acid composition of oil-loaded microcapsules were made. Furthermore, investigations of morphology and thermal behavior, as well as a Fourier transform-infrared (FTIR) analyses of microcapsules, were performed.

RESULTS
The values of EE, LC were approximately 53-65% and 187-231 g kg-1, respectively. Studies found that the plasmolysis treatment increased EE and LC and decreased the mean peroxide value (PV) of microencapsulated oil. The presence of purslane seed oil in yeast microcapsules was confirmed by FTIR spectroscopy and differential scanning calorimetry analyses. The lowest rate of oxidation belonged to the oil-loaded plasmolysed CMC-coated microcapsules (16.73 meqvO2 kg-1 ), whereas the highest amount of oxidation regardless of native oil referred to the oil-loaded in non-plasmolysed cells (28.15 meqvO2 kg-1 ).

CONCLUSION
The encapsulation of purslane seed oil in the yeast cells of S. cerevisiae can be considered as an efficient approach for extending the oxidative stability of this nutritious oil and facilitating its application in food products. © 2017 Society of Chemical Industry.


We reexamine the nucleosynthesis predictions for the simplest class of scalar-tensor theories of gravity, the Jordan-Brans-Dicke theory. Comparison with present observational data on light elements' abundances provides bounds on the ω-parameter which are as strong as the post-Newtonian ones, or even stronger, depending on the value of Ωh2. Future improvements in the determination of the 4He and D+3He abundances will increase this bound dramatically. We argue that a future (hypothetical) experimental deviation from general relativity prediction could be restored by a Jordan-Brans-Dicke theory.

National data indicate that the rate of decline in mortality from coronary heart disease has been more rapid in whites than in African-Americans [1-4]. Among the many possible explanations for this discrepancy is reduced access to beneficial care, including sophisticated cardiologic procedures. Wenneker and Epstein [5] showed that African-Americans were significantly less likely than whites to have cardiac procedures in Massachusetts hospitals in 1985. Maynard and colleagues [6] found that African-Americans in the Seattle-based Myocardial Infarction Triage and Intervention (MITI) Registry had significantly fewer angioplasty and coronary artery bypass grafting procedures than did whites. Goldberg and colleagues [7] analyzed national Medicare data from 1986 and showed that among persons insured by Medicare, African-Americans had a significantly lower rate of coronary artery bypass grafting procedures when compared with whites. Unfortunately, these studies lacked sufficiently detailed clinical information to determine whether these differences were a function of differing clinical characteristics or even whether the rates were higher than appropriate in whites, lower than appropriate in African-Americans, or both. For example, African-Americans have a significantly lower rate of hospital discharge with acute myocardial infarction as the primary diagnosis [8]. Although ischemic heart disease is the leading cause of death in African-Americans as well as in whites, the effect of race on clinical course and outcomes (that is, on the natural history of ischemic heart disease) in patients with chest pain has not been well studied [9]. Thus, further information is needed to understand racial differences in the rates of cardiac procedures. To address this need, we merged detailed clinical and resource utilization data on 3031 patients from two hospitals to measure the effect of race on the clinical presentation, the natural history of disease, and the resource utilization of patients coming to the emergency department because of acute chest pain. Our detailed patient-specific information permitted us to adjust for clinical characteristics and complications to understand the basis for any differences in overall procedure rates. Methods Study Design The Multicenter Chest Pain Study, a cooperative investigation of the clinical characteristics and outcomes of emergency-department patients with acute chest pain, was conducted between December 1983 and October 1986 [9-18]. All patients 30 years or older who came to one of the participating emergency departments with a chief complaint of anterior, precordial, or left lateral chest pain that could not be explained by obvious local trauma or abnormalities on a chest radiograph were eligible. The emergency-department physician, who was usually an intern or a resident, recorded clinical data at the time of presentation, including the patient's age; sex; findings from the history, physical examination, and electrocardiogram; and results of cardiac enzyme assessments. The emergency-department physician or a research nurse recorded these data on a standardized data form that was part of the permanent medical record at a time when he or she had no knowledge of, and could not be biased by, the patient's subsequent course. Data on race were collected prospectively in 94% of patients at the University of Cincinnati Hospital and retrospectively, by chart review, in 96% of patients at the Brigham and Women's Hospital. Patients from these two hospitals composed our study group. The term African-American is used to describe blacks residing in the continental United States who are of African descent. Each patient visit was considered an individual event. Only the first three visits for each patient during the study period were included in the analysis. Patients who experienced cardiac arrest in the emergency department were excluded from the study. During the study period, 4173 potentially eligible patient visits occurred at the two hospitals (Figure 1). A trained study nurse reviewed the charts of all admitted patients, recording data on cardiac enzyme levels, official discharge diagnoses, and dates and times of complications and procedures. Figure 1. Derivation of the study population of 3031 patients from the 4173 patients who came to the emergency department with acute chest pain. Consent was obtained from 1991 (79%) of the 2522 discharged patients. The other 531 nonconsenting, discharged patients did not differ significantly from the 1991 consenting patients in terms of gender or age. Consenting, nonadmitted patients were retained in the study only if the investigators, who were blinded to all of the patient's emergency-department data, thought that the follow-up information was sufficient to place the patient into a diagnostic category, as defined below. Sixty-two percent of the consenting, nonadmitted patients included in the final study sample had a follow-up assessment of cardiac enzyme levels, and 66% had either assessment of cardiac enzyme levels or a follow-up visit. Those nonadmitted patients who did not return for follow-up evaluation were contacted by telephone to assess their clinical status. In such cases, patients considered to be at a higher risk for myocardial infarction because of a suspicious pain description, electrocardiographic abnormalities, or continuing symptoms were encouraged by telephone to return for an evaluation; if they were still unwilling to return, further follow-up was obtained by telephone and contact with the patient's personal physician. Patients who returned for a follow-up visit or enzyme assessment were similar to patients who received telephone follow-up with regard to sex and age, but African-Americans were more likely than whites to have enzyme assessments, electrocardiograms, or both (71% compared with 61%, P < 0.0001). Race was identified in 1593 (97%) of the 1640 admitted patients and 1676 (94%) of the 1787 consenting, discharged patients with adequate follow-up. The 226 Hispanic and 12 Asian patients were excluded because of their small number. Therefore, the final study sample included 3031 patients: 1508 admitted patients (35% African-American, 49% male) and 1523 consenting, nonadmitted patients (55% African-American, 39% male). Data on zip-code and insurance status were available from one of the two hospitals. Household income was estimated by matching zip codes with 1980 census data on median household income in that geographic location. Diagnoses A final diagnosis of acute myocardial infarction was made in both admitted and nonadmitted patients on the basis of one of the following criteria: 1) characteristic evolution of serum enzyme levels, as defined by the detection of creatine kinase MB isoenzyme levels in more than trace amounts by the qualitative electrophoretic assay or as at least 5% of an elevated total creatine kinase level and showing a typical rise and fall by the quantitative assay; by a lactic dehydrogenase isoenzyme 1 level that was greater than the isoenzyme 2 level in the absence of hemolysis or renal infarction; or, if isoenzymes were not assayed, by serial total creatine kinase levels demonstrating a typical rise and fall, with a peak value exceeding twice the usual upper limit of normal; 2) an electrocardiogram showing development of pathologic Q waves [at least 0.04 seconds in duration] and at least a 25% decrease in the amplitude of the following R wave compared with that of the emergency-department electrocardiogram; and 3) sudden unexplained death within 72 hours of presentation. In the Chest Pain Study, the purpose of which was to define optimal management strategies for patients with acute chest pain, discharged patients with sudden death within 72 hours of admission were classified as having had an acute myocardial infarction unless contradicting data were found, because admission to an intensive or coronary care unit would have been the preferred triage strategy had this outcome been anticipated. Admitted patients who had sudden cardiac arrests and died before cardiac enzyme assessments could be done were similarly classified unless other explanations for the arrest emerged. In all of these patients, the presenting characteristics, electrocardiograms, and clinical courses were most consistent with the diagnosis of acute myocardial infarction. All patients who underwent coronary reperfusion with thrombolytic therapy showed electrocardiographic or enzymatic evidence of acute myocardial infarction before undergoing the procedure. Patients who showed creatine kinase and creatine kinase MB isoenzyme elevations after but not before an invasive procedure (for example, coronary arteriography, coronary angioplasty, or coronary artery bypass grafting) were considered not to have had infarctions, because such procedures were done at the discretion of the physicians who were caring for the patients, and acute myocardial necrosis might not have occurred if the patients had been managed conservatively. The final diagnosis of acute ischemic heart disease was made if the patient was found to have either acute myocardial infarction or unstable angina. Unstable angina was diagnosed if 1) the patient's original emergency-department chest pain syndrome was either new or worse (in frequency, severity, or duration) than his or her chronic anginal syndrome; and 2) the diagnosis of angina was made by the senior clinician associated with the case. Table 1. Characteristics of the Study Sample Stratified by Race* Major complications were defined as follows: ventricular fibrillation requiring lidocaine or defibrillation, Mobitz II second-degree atrioventricular block requiring temporary or permanent pacing, new complete heart block, cardiogenic shock, or cardiac arrest. Cardiac catheterization data were collected retrospectively by chart review. Statistical Analysis Racial distribution differed by hospital, with African-Americans accoun

Take a little, leave a little. But they always take more then they leave by the basic nature of the vampire process of inconspicuous but inexorable consumption. The vampire converts quality-live blood, vitality, youth, talent – into quantity – food and time for himself. He Perpetrates the most basic betrayal of the spirit, reducing all human dreams to his shit.

Trust is key to achieving successful Human-Robot Interaction (HRI). Besides trust of the human co-worker in the robot, trust of the robot in its human co-worker should also be considered. A computational model of a robot's trust in its human co-worker for physical human-robot collaboration (pHRC) is proposed. The trust model is a function of the human co-worker's performance which can be characterized by factors including safety, robot singularity, smoothness, physical performance and cognitive performance. Experiments with a collaborative robot are conducted to verify the developed trust model.

the animation industry is growing drastically. This results in increasing demand for better performance and reduction of process time and cost. One of the most important processes is Lip-synchronization. Generally, in creating an animation, this process can cost a lot of time and expenses. In this project, we will research about how to create the Lips Synchronization model. There are two main parts that we will focus. First, the force-alignment which is used to analyst wave files and generate them with the length of time used in each phoneme separately. Second, creating the animation, the label output from force-alignment will be collected and used as an input to this part. In this process, we will develop an object model, link armatures to it by using the facial animation method as a reference. The output result of this project is the animation model that the viseme can move synchronously with the sound waves and the length of time used in each phoneme. Therefore, this model can be used to develop the Lip-synchronization process and will also help improving the animation industry in the future.


Recent work has demonstrated that per-thread compositional verification of value-dependent noninterference is feasible for concurrent programs: Murray et al. [9] presented a type system that, when applied individually to each of the threads of a concurrent program, can be used to establish that the entire program does not at any time leak high-classified data to any presently low-classified, readable memory. However, the gap remains that the verification of this (necessarily timing-sensitive) property for the source code of a program may not guarantee that the property still holds for that program once it has been compiled and is running on actual hardware. Anticipating this, Murray et al. [9] also presented and proved sound a per-thread compositional notion of refinement that guarantees that an implementation of some verified system enforces the same noninterference property at the level of the target language's semantics. My present work is now seeking to apply and extend this result by producing the first per-thread compiler that provably guarantees to preserve such a concurrent noninterference property. To this end, I have adapted and implemented in the Isabelle/HOL theorem prover [10] an existing compilation scheme (developed by Tedesco et al. [14]) from a generic imperative While language to a generic RISCstyle assembly language, and proved that my compiler preserves the compositional value-dependent noninterference property from [9]. This means that you can use it to compile each of the threads in such a program separately and obtain a proof that their compiled assembly implementations compose into a concurrent system that satisfies value-dependent noninterference at the level of the RISC-style target language (which for short we will subsequently refer to as RISCLang). As a proof of concept, I have exercised this compiler on a concurrent While model of the Cross Domain Desktop Compositor (CDDC) [2] verified with Murray et al. [9]'s type system, and instantiated all of the related proofs of


The purpose of this paper is to study about resource reservations under the broadband networks. When network bandwidth gets more considerable, the applications about real-time service are getting more popular and important. The best-effort service can't support real-time services well, so several new service classed have defined. We hope that users can reserve the network resource and preserve the resource for a period of time required. Of course, we would not like to waste the network bandwidth. In this paper, we use a dynamic ATM network model ads our simulation model. In the simulation model, a LAN environments is considered to illustrate the reservation cell loss rate. Three kinds of scenarios are assumed as our retry reservation cell scheme in the simulation. We expect to reduce the reservation cell failure rate by proposed methods. The simulation results show that a better performance can be achieved.


FLC( FLOWERING LOCUS C) in Raphanus species were identified using data mining method from Raphanus EST database. The full length CDS sequence of Arabidopsis thaliana vernalization pathway key gene FLC was used as reference to search the homologous ESTs in Raphanus EST database. Sequences with Score ≥100,Evalue ≤10-10and coverage ≥70% were considered as the candidate FLC-gene-like ESTs,which were assembled and annotated in the following analysis. The results showed that 70 FLC-gene-like ESTs were identified in Raphanus,and four FLC candidate genes( RsFLCa,RsFLCb,RrFLCa and RrFLCb) were predicted,among which RsFLCa and RsFLCb were originated from Raphanus sativus,and the other two were originated from Raphanus raphanistrum. The homologous FLC genes in Raphanus and Arabidopsis thaliana shared 78. 7%-86. 9% nucleotide sequence identity,and paralogs FLC genes in Raphanus shared 75. 9%-93. 4% nucleotide sequence identity. Identities of FLC orthologs between Raphanus and Brassica were more than 85%,which was higher than that between Raphanus and A. thaliana. Moreover, phylogenetic analysis suggested that multi-copy of FLC genes in Raphanus may be corresponded with genome polyploidy of Raphanus spieces,which was similar to that of FLC genes in Brassica species.

The financial crisis associated with the COVID-19 pandemic has exacerbated food insecurity in the United States. The emergency provides an opportunity to re-think the American nutrition-assistance system. In this paper, we describe findings from a community-based project conducted in urban Alaska before the pandemic in collaboration with a local food pantry. We conducted semi-structured interviews with nineteen food recipients, half of them twice, about how they procure food and prepare their meals in the context of juggling other expenses and demands on their time. What participants in our study do fits mainstream American patterns. Our study adds to the knowledge base by focusing on how families think strategically about their situations in context. In addition to cost, participants take nutrition and flavor into account. Most importantly, they do not think about assistance programs in isolation but holistically.


In order to analyze crustal structures and features in the conjugate margins of South China Sea(SCS),we collected large numbers of studied results from the ocean bottom seismometers experiments,onshore-offshore seismic experiments,gravity and magnetism anomalies.This paper firstly constructs three land-sea super cross-sections from east to west in the northern margin of SCS.The results show the onshore-offshore transitional zone is a border separating the unstretched and the stretched continental crust.The low velocity layer(LVL) in the middle crust was widely imaged in the unstretched continental crust.However,the high velocity layer(HVL) in the lower crust was detected in the stretched continental crust.By analyzing the mechanisms of the LVL in the middle crust and HVL in the base of crust,we believe the crustal structures had distinctly different attributes in the continental South China and in the northern SCS,which indicates that the littoral fault zone(LFZ) could be the boundary fault between them.Then,we reveal the crustal features in the Liyue Bank based on water depth,gravity and magnetism anomalies.The Moho depth thins from about 24 km in the Liyne bank to 11 km in the oceanic basin.The ocean-continent transitional zone generally widens from east to west in the southern margin.Finally,we devide the crustal structure in the conjugated margin of SCS into four types,including the unstretched continental crust,the stretched continental crust,the ocean-continent transitional zone,and the ancient ocean crust.


Aiming at the vibration signals are nonlinear and time-varying since the no-load closing of a transformer, a fault feature extraction method that combines local mean decomposition (LMD) and Hilbert marginal spectrum energy entropy is proposed. Several product function (PF) components that reflect the mechanical state information of operating process are extracted by LMD. The top 6th order components that are selected based on the energy distribution and correlation coefficients, are transformed by Hilbert transform, and their marginal spectrum energy entropy are calculated as the feature quantities. Grid search algorithm is used to optimize the support vector machine classifier to identify the different states of transformer winding. The experimental results show that the features based on LMD-Hilbert marginal spectrum energy entropy extraction can accurately reflect the fault characteristics, and the SVM diagnosis method has a good effect on in the case of a small number of samples.


From a genomic library of Lactobacillus reuteri ATCC 55739, one clone, NE347, carrying a pyrH gene encoding UMP kinase, was identified. pNE347 carried a 1.88 kb EcoRI fragment and the pyrH was located in the middle of the insert. pyrH ORF was 723 bp in size and capable of encoding UMP kinase composed of 240 amino acid residues, tsf encoding an elongation factor-Ts and frr encoding a ribosomal recycling factor were present upstream and downstream of pyrH, respectively. When introduced into E. coli KUR1244, a pyrH-negative strain, pNE347 restored the ability to grow at 42°C, indicating that pyrH from L. reuteri synthesized functional UMP kinase in E. coli. Northern blot experiment showed that pyrH and frr were cotranscribed as a 1.4 kb single transcript. pyrH was overexpressed in E. coli by using a pET26b(+) vector, and a major 25 kDa protein band appeared on SDS-polyacrylamide gel.


The article addresses problems of population aging in Poland and the selected environmental hazards exerting a negative impact on seniors' health. The introduction presents the reasons underlying the above-mentioned aging process and provides the characteristics of the primary environmental threats. The next part covers the most important trends and indicators related to the demographic situation in the country. The core of the study is focused on presenting and interpreting the results of empirical research on the periodization of the population aging process in Poland, in the years 2004–2019, using the multidimensional statistical analysis method including, in particular, the data classification method. The key demographic factors differentiating the development phases of the population aging process include, in order of their significance: longer life expectancy of the population, narrowed gross reproduction rate, declining birth rate, and total migration balance. In addition, the article provides the analysis of the selected environmental threats' impact on population aging in Poland, among which the following were indicated: high temperatures, solar conditions, heavy rainfall, strong winds, droughts, and fires. Moreover, the process of longer life expectancy in fine health is essentially related to two issues: the level of medical care, with particular attention paid to check-ups and preventive measures, and the promotion of a healthy lifestyle. In summary, it should be highlighted that the elimination of all pollutants or the reasons of environmental hazards is not possible; however, the actions primarily focused on reducing the emission of harmful gases into the atmosphere and other forms of environmental pollution should definitely be taken.

The percentage of poor people does not affect to the HDI. Government expenditures in the field of education have no effect on HDI. Government expenditures in the field of health have a significant positive effect on HDI and income inequality has no effect.


A nonurban base line has been established for nine trace element constituents of aerosol particles as a function of particle size at ground level sampling stations in north Florida up to 50 km from the Gulf of Mexico. The particle size range 0.25- to >4-μm aerodynamic diameter was investigated by cascade impactor sampling and elemental analysis by proton-induced X ray emission. By using a strategy of sampling at urban, forest, and coastal locations and by choosing approximately 48-hour sample averaging intervals the potential dependence of the base line levels both on local pollution and natural sources and on local particle size specific aerosol removal processes could be evaluated. It is found that elements contained in the largest particles, especially those of >4 μm, display the greatest degree of average concentration difference between sites, a result suggesting short atmospheric residence times and the importance of local dispersion sources and atmospheric cleansing processes in regulating the particle concentrations in air. Elements contained in particles of <2-μm diameter show little average concentration difference between sites unless they are influenced by local pollution sources, a finding suggesting that their concentrations in air are regulated by large-scale sources and transport processes. Sulfur in the smallest particles shows a marked constancy of concentration, but it may be modified in the largest particle size ranges in relation to proximity to the seacoast. No evidence is found for dependence of particulate sulfur concentrations on local pollution sources. K, Ca, Ti, Fe, and Zn appear to be regulated in the main by terrestrial source processes, and Cl by marine source processes, but Br and Pb appear to be accounted for adequately by assuming automotive fuel combustion as their major source. Limited data obtained for V indicate that it may vary considerably with fluctuations in aerosol transport from oil-fired electric power plant sources in the region. Limited additional data also suggest that Mn is derived from sources of natural terrestrial composition. In view of these findings, certain criteria may be set for the design of a meaningful nonurban aerosol monitoring network.


This paper is concerned with the problem of multiuser precoding design for multiple-output multiple-input (MIMO) two-way relay transmission. In the literature, most of existing studies on multiuser transmission over two-way relay channels have assumed that user terminals (i.e., source nodes) are equipped with a single antenna. To increase the capacity of the multiuser two-way relay network, this paper introduces precoding designs at source and relay nodes for space division multiple access (SDMA) transmissions between source nodes. Numerical simulation results show that the proposed precoding designs at multi-antenna source nodes (i.e., user terminals) can improve the capacity of the network.


The article addresses the problems of the evaluation methodology improvement of the transport service efficiency and quality provided to passengers on suburban bus routes in accordance with the modern management system requirements. The purpose of the study is to provide practical recommendations to motor transport enterprises following which they can improve the level of service provided to suburban bus route passengers, as well as to provide a structured approach that will allow transport organizations to respond objectively and reasonably to requests resulting from new passenger transportation needs. For a comprehensive assessment of quantitative and qualitative transport service indicators, the evaluation method of the transport service efficiency is proposed. This approach makes it possible to reflect the transport service level both through the prism of enterprises` operation efficiency and the quality of transport service provision. The results of the study are of practical importance in the application of such methods in motor transport enterprises` activity providing the necessary information for management in modern business conditions.

The findings indicate that (a) 12 basic hardware and software skills and 13 Internet/Web-centered communication skills are important for all business professionals now and toward 2005, (b) programming skills are important mainly for IT professionals, and (c) skills of using discipline-specific information systems are important for professionals in the respective disciplines, and these systems are considered as integrated components of Web-enabled enterprise systems such as ERP and SCM.


This paper highlights the issue of whether government bonds are net wealth as an important one in the monetarist controversy. In particular it is shown that the standard IS-LM model and its conclusions arise as a special case of a more general macroeconomic model which results when government bonds are fully perceived as collective wealth. When, however, the tax liabilities required to service that debt are fully capitalized, a model with monetarist conclusions emerges.


A respiratory disease emerged in a beef cattle farm of Chongqing,which caused lesions primarily in lungs.Four bacterial isolates(designated CQ1,CQ2,CQ3,CQ4) were isolated from the lung tissues,liver and blood samples,respectively.16S rRNA sequence analysis showed 99.9%,99.8%,99.9% and 99.9% homology between the CQ1 and Mycoplasma bovis,CQ2 and Helcococcus ovis,CQ3 and E.coli,CQ4 and Salmonella,respectively.CQ1 isolate was identificated as M.bovis based on culture characteristics,colonial morphology and specific gene identification by PCR.The drug susceptibility and pathogenicity to animal showed that CQ1 isolate was sensitive to ciprofloxacin,floxacin,etracycline,spectinomycin and non-lethal to mice.Drug treatment and laboratory detection showed the disease was primarily caused by M.bovis.

The propagation direction of electromagnetic waves is not always straight and if the direction of wave changes in bounded medium, it encounters bending loss. This loss is due to reflection of wave from chamfer less bends. Thus, for direction change in bounded medium without incurring bending loss, these bends have been designed. The study contributes the designing and analysis of right angled E and H plane chamfered microwave bends in proposed rectangular substrate integrated waveguide. These newly designed bends are optimized in X-band frequencies [8–12 GHz] for super high frequency of 11 GHz. The proposed designs are built on FR4 epoxy substrate. By using these bends, different waveguides in X-band can easily bend into required position. These designs have return loss of −51.9035 dB and −50.4673 dB and voltage standing wave ration (VSWR) of 1.05 and 1.04 respectively. Hence, the high performance of proposed designs indicates that the bends are very efficient to transmit signal in radar and satellite communication. The bends are analyzed and simulated using high frequency structural simulator (HFSS) 15.


Introduction: The umbilical cord anomalies directly effect on the life quality of the fetus. It can lead to fetal death or many problems during pregnancy and delivery. Early detection of these abnormalities is of particular importance. Case Presentation: We report a case of thin cord syndrome (TCS) in a 30-year-old pregnant woman with suprapubic pain. After termination of pregnancy, histopathologic assessment confirmed the TCS. Conclusions: In all cases with suspected abortion, the umbilical cord disorder should be considered.

The Strategy of Waste Management, Horizon 2014-2020, states 8 major objectives with the role of establishing new priorities for Waste Management. Thus, one of the proposed measures for the next 5 years is encouraging the wastes exploitation for energy recovery. In this context, the main goal of our study was to evaluate the level of pollution considering 5 closed municipal waste dump sites from the North-East region of Romania over the period 2013-2015, having in mind at a first glance, the possibility of methane emissions valorization in the form of biogas. Rapid Impact Assessment Matrix and Leopold's Matrix were used for the environmental impact assessment. The results of the environmental impact assessment showed that the impact on environmental quality was very high for Vaslui and Iasi counties, due to pollution migration from North to South of the studied region, and from one environmental component to another (e.g. from soil to ground water). On the other side, the results obtained by monitoring the emissions generated by the waste dump sites from Botosani County revealed there is a major impact an air quality. The overall impact, quantified by two conventional methods shows that at regional level, heavy metals are the most contributing pollutants to environmental impact, thus it is necessary to implement measures to remediate and protect soil and ground water quality. The results of this study revealed that there are no major negative impacts or fire risks directly generated by waste dump sites, and biogas is not valuable for energy recovery goals.


AIM To establish a post-column derivatization method with ninhydrin for the determination of alanyl-glutamine,and to estimate the compatible stability of it.METHODS A strong-acid cation-exchange column(PEEK,4.6×150 mm,7μm) were employed to determine the concentration of alanyl-glutamine with a mobile phase of phosphate buffer at the flow rate of 0.45 mL·min~(-1).Column temperature was 130℃.The detection wavelength was 570 nm.The changes before and after compatible application of alanyl-glutamine with sodium chloride injection,5%glucose injection,5%glucose and sodium chloride injection,10%fructose, Ring's solution,compound amino acid and amino acid compound microelement on color,clarity and concentration were determined.RESULTS The linear range of alanyl-glutamine was 1-20 mg·L~(-1)(r = 0.997 9). The recovery rates were 94.5%,97.6%and 98.7%,and RSD were 0.52%,0.10%and 0.06%,respectively. There were no obvious changes on color and clarity before and after compatible application of alanyl-glutamine with the other injections in six hours.There were no significantly difference(P0.05) in the variation of alanyl-glutamine contents comparing with compound amino acid and 5%glucose injection in 0 - 6 hours.But there was significant difference(P0.01) between the other groups of fluids comparing with alanyl-glutamine. CONCLUSION This method is simple and accurate with good resolution,and is suitable for the determination of alanyl-glutamine.The best carriers of alanyl-glutamine are compound amino acid and 5%glucose injection.


Enforcing international law remains problematic: what happens if a sovereign state refuses to comply with its obligations, even after an international adjudicatory body has ruled in its disfavour? The solution offered under the World Trade Organization (WTO) system has been to authorize the prevailing member in the settlement of a dispute to retaliate, if and when the respondent member fails to implement a panel or Appellate Body ruling. Such retaliation can take the form of additional restrictions on imports of goods or services, or suspensions of intellectual property rights. Our article examines whether fairer and more effective means of ensuring compliance could be inserted into the WTO system. First, existing remedy systems are outlined, comparing general public international law with the current WTO system. We posit that the objective of both is rule compliance and take issue with the recent theory of efficient breach. Further support is drawn from the EU compliance regime. This is followed by an examination of the advantages of introducing financial remedies in WTO dispute settlement as well as a refutation of potential objections. The main elements of the subsequent proposal relate to the calculation, term, retro-activity and beneficiary of financial payments as a remedy. The Author 2013. Published by Oxford University Press.

For curing the common cold due to windcold , bosom frowsty cough, feng shui edema, bronchial asthma disease and etc, DL-ephedrine was synthesized by taking α-(Methylamino) propiophenone as the starting material followed reduction reaction. L-(-)-dibenzoyltartaric acid was used to resolve DL-ephedrine to get optically pure isomers D-(-)-ephedrine and L-(+)-ephedrine.Chemical structure was confirmed by IR and optical purify was up to grade.


The retention behaviour of some chloropyridine isomers on silica, cyano-silica and amino-silica columns in normal phase liquid chromatography has been studied. Retention times on first two columns follow similar,pattem while is different on amino-silica column. An equation for inter comparison of columns for selectivity purpose is developed and verified. Log k' versus log X B plots follow Snyder and Soczewinski model of adsorption. A mixed interaction of involving hydrogen bonding and dipolar interactions are responsible for the retention of solutes on silica and cyano-silica columns and weak hydrogen bonding interaction lead to separation on amino-silica column. Cyano-silica column is preferred for their separation considering the retention times. However, best selectivity is seen for monoisomers and 2,6-DCP on either silica or cyano-silica column and 3,5-DCP and 2,3,5-TCP on amino-silica column.


Concerning to the present problems,the structure of a new type of non-leakage vertical self-priming pump is improved by fitting impeller and vane together,setting ribbed slab in moisture separation chamber to shorten the self-priming time,taking special structure at inlet to prevent siphonage without using check-valve or vacuum breaking valve,and adopting rotating dynamic seal and framework oil seal to avoid the problems such as leakage of packing seal and maintenance for mechanical seal.According to the comparison of the pre and post structures′ test results,it is concluded that the gap between vane and impeller and the structure of rotating dynamic seal have great effect on self-priming performance,and it is necessary to balance the axial force.Improved approach and analysis calculation which are useful for reasonable design are recommended in detail associated with experimental data.


With the development of the technology about computer and image processing, non-contact detecting technology basedon machine vision has been widely used, and it has been becoming possible to apply the related technology in the defect detectingof PCB component. By means of the OpenCV vision library, PCB components image is processed through smoothing filter, binarization processing and edge detecting. Then, compare the processed PCB image with the standard template image to determine whether there are defects on PCB component. Experimental results show that compared to the traditional methods, using OpenCV for image processing can improve the efficiency of detection and the integration of program.


[Objective] To study the expression of endoplasmic reticulum molecular chaperon in gastric mucosa infected with Helicobacter pylori. [Methods] Semi-quantitative RT-PCR method was used to examine the mRNA expression of Grp94, Grp78 and PDI in H. pylori infected and non-infected gastric mucosa. Western blot method was used to examine the expression level of Grp94, Grp78 and PDI protein in infected and uninfected gastric mucosa. [Results] The expression of Grp94 mRNA , Grp78 mRNA and PDI mRNA were (0.424±0.055), (0.8038±0.0500), (0.5704±0.0794) in uninfected group(28 cases) respectively; Grp94 mRNA, Grp78 mRNA, PDI mRNA were (0.882±0.082), (1.1586±0.0839), (1.0642±0.1533) in infected group(32 cases) respectively. The expression amounts of Grp94, Grp78 and PDI protein were (0.427±0.0360), (0.4345±0.0545), (0.5198±0.0379) in uninfected group. In infected group the expression of protein amounts of Grp94, Grp78, PDI were (0.671±0.072), (0.6204±0.0412), (0.8252±0.032) respectively. The expression amounts of Grp94 mRNA, Grp78 mRNA, PDI mRNA and Grp94, Grp78 and PDI protein in infected group showed great increase (P 0.01) respectively. [Conclusions] Helicobacter pylori infection may increase the expression of Grp94, Grp78 and PDI at mRNA level in gastric mucosa, meanwhile, it also increases the synthesis of protein.

Peculiarities of defects of worn-out matrix drilling bits, occurred during service, were considered. The degree of wear of working parts of seats under diamond-hard-alloy cutters was investigated. Methods of preparation of worn-out areas of working parts for their restoration by arc surfacing were optimized. It is shown that to restore the defective areas of crosspieces of holes of diamond-hard-alloy cutters of body blades, alloy of Kh20N80 grade was recommended as the best one, while TeroCote 7888T alloy was the best one for hole substrates. It was found that protective coating TeroCote 7888T deposited on alloy VK10, provides the most effective protection from erosive and abrasive wears. Basing on the obtained data, the technology of restoration of working parts of blades of matrix bit bodies has been developed. These bits after their restoration were transferred to the customer and at present they are passing the industrial trials at the enterprise of the Poltava region in drilling gas and oil wells. 7 Ref., 4 Figures.


ABSTRACT In this article, calix[4]arene (4) was prepared by debutylation and hydrolyses reacting from 25,27-dibenzoyl-26,28-dihydroxy-5,11,17,23-tetra(tert-butyl)calix[4]arene (2). Azocalix[4]arenes (6a-c) were coupled by linking 4-methoxy, 4-ethyl, and 4-nitroaniline to calix[4]arene (4) through a diazo-coupling reaction. Thermal behavior characteristics and decomposition routes of 25,26,27,28-tetrahydroxy-11,23-di(tert-butyl)-5,17-(p-substitue phenyl)azocalix[4]arene (6a-c) were investigated in air atmosphere by means of thermogravimetry (TG), differential thermogravimetry (DTG), and differential thermal analysis (DTA) analyses. It was found that the decomposition of all compounds complete with two exothermic stages which corresponded to removal of substitute groups (methoxy-, ethyl-, nitro-) and second stage rest of structure decomposition.


Abstract Griminger et al. (1953a, b) and Hare et al. (1953) have reported the occurrence of hemorrhages and prolonged blood clotting time in battery-reared chicks fed simplified corn-soybean oil meal type rations containing no alfalfa meal or other source of supplemental vitamin K. Griminger et al. (1953b) found that the addition of 15 ppm. oxytetracycline (terramycin), or 50 ppm. 3-nitro-4-hydroxy-phenlarsonic acid significantly prolonged the blood clotting time. Para-amino-phenylarsonic acid (arsanilic acid), at a level of 100 ppm., also prolonged the clotting time, although not significantly. In view of the recent occurrence of hemorrhages in certain flocks reared under field conditions, and its possible relation to vitamin K deficiency, similar observations made in this laboratory are presented. Day-old, straight-run New Hampshire chicks, obtained from a commercial hatchery, were distributed into 9 groups of 15 chicks each and reared to 4 weeks of age in an electrically heated battery with raised wire floors… .


The ship from Toldar was first sighted from earth by a Kenyan University observatory. The news travelled fast and soon the ship was being tracked from everywhere. There was a world-wide boom in telescope sales, UFO garbage, and doomsday proselytes. The shuttle program suddenly had funding, as did the worlds' air forces, and weapons research centres. Even Russia kick-started their space program again, and goodness knows they could not afford it.


Abstract : Despite the automatic fire alarm system, according to the national fire data system of national emergency management agency, the fires account for 40,932 incidents, 2,184 injuries and about 430 billion won in property losses in 2013. Since the conventional automatic fire alarm system has several weaknesses related to electrical signal such as noise, surge, lighting, etc. Most fires are mainly caused by electrical faults, mechanical problem, chemical, carelessness and natural. The electrical faults such as line to ground fault, line to line fault, electrical leakage and arc are one of the major problems in fire. This paper describes the development of a novel real-time fire monitoring system algorithm including fault detection function which puts the existing optic smoke and heat detectors for fire detection with current and voltage sensors in order to utility fault monitoring using high accuracy DAQ measurement system with LabVIEW program. The fire detection and electrical fault monitoring with a proposed a new detection algorithm are implemented under several test. The fire detection and monitoring system operates according to the proposed algorithm well.


*A study on the application of glycidyl azide polymer (GAP) to hybrid rocket motors is presented. Efforts were made to spread the burning rate spectrum of GAP, especially to lower side, and the dilution with an inert polymer was selected. Polyethyleneglycol (PEG) was chosen as the diluent from its functional groups, excellent solubility with GAP and relatively high density and low cost. Dilution of GAP with PEG effectively reduces the linear burning rate without the change of pressure exponent and suppresses the self-combustibility beyond a certain critical concentration of PEG. Two types of hybrid motor, gas hybrid type and conventional type, are considered, and mixtures keep the self-combustibility are used as solid fuel for gas hybrid rocket and mixtures lose that are for conventional hybrid rocket. The firing tests have been conducted with small test motors whose inner diameters are 80mm, and the results are presented and discussed.


The study was conducted in Salempur and Bhatpar Rani Blocks of Deoria district in Uttar Pradesh to ascertain women participation in vegetable production. 120 houses having land for vegetable cultivation were selected. 60 rural women from 60 houses selected from each block. Female respondents from each house were interviewed. The data were collected personally through structured interview schedule. Data collected included the extent of participation and decision making of women in various activities of vegetable production. Study revealed that in vegetable cultivation various intervention points are addressable. Women were involved in operations such as cleaning of land, sowing of seed, transplanting of vegetable nursery, hoeing and weeding, scaring of birds and rodents, harvesting and processing of vegetable and storage of seed. Non participation of women in various operations was due to more fatigue, requirement of more muscle power, lack of knowledge and awareness with respect to decision making. It was observed that women played only supportive role and less participation of women in decision making could be attributed to customs, traditions, social barrier, their illiteracy, ignorance and less participation in extension programmes. Women' education, technical training and adequate extension facilities can create a positive impact leading to a better tomorrow.


BARRETT'S ESOPHAGUS is a condition in which an intestinal-type epithelium called specialized intestinal metaplasia or Barrett's metaplasia replaces the stratified squamous epithelium that normally lines the distal esophagus.1 Barrett's esophagus develops as a consequence of chronic gastroesophageal reflux disease and predisposes to the development of adenocarcinoma of the esophagus.1 Barrett's esophagus is usually discovered during endoscopic examinations in middle-aged and older adults whose mean age at the time of diagnosis is approximately 55 years.1 Although arrett's esophagus can affect children, it rarely occurs before he age of 5 years.2 This observation supports the hypothesis hat a Barrett's esophagus is an acquired condition in the vast ajority of patients. The male-to-female ratio is approximately :1.3 The columnar metaplasia of a Barrett's esophagus causes no symptoms. Most patients are seen initially for symptoms of the associated gastroesophageal reflux disease such as heartburn, regurgitation, and dysphagia. Estimates of the frequency of Barrett's esophagus in the general population have varied widely, ranging from 0.9% to 4.5% depending in part on the population studied and the definitions used.4,5 The overall reiability of endoscopy with a biopsy for the detection of Barett's esophagus is approximately 80%.6 A case of esophageal issection after transesophageal echocardiography (TEE) perormed during mitral valve repair in a patient whose past edical history was positive for Barrett's esophagus is preented.


SARS corunavirus is an emerging virus. A lot of animals could be infected by SARS-CoV and Himalayan palm civets, as one of important hosts, is an ideal animal model. Viral genetic factors have been implicated in the emergence of SARS-CoV, with the suggestion that this virus is a recombinant between mammalian and avian coronaviruses. However, the recombination is unlikely to explain the appearance of SARS in humans.


The interaction of electromagnetic waves guided by plane duct with enhanced plasma density in homogeneous background magnetized plasma is considered. The parametric instability of the guided waves propagating in the opposite directions is analyzed in the cases where the magnetoplasma is either nonresonant or resonant. For some practically interesting cases, numerical results illustrating the wave interaction are presented.


A Coronavirus disease 2019 (COVID-19) outbreak, has rapidly swept around the world just within a month, causing global public health emergency. Ground glass opacities, consolidation, and crazy paving pattern are typical chest computed tomography (CT) manifestations; otherwise, pulmonary pneumatoceles are a rare evolutionary aspect. Herein, we report a case of a 53-year-old male who was diagnosed with COVID-19 pneumonia on the basis of RT-PCR analysis with a pneumatocele formation in bilateral lobes of the lung on follow-up chest CT scan. The aim of this report is to highlight this atypical radiological evolution of COVID-19 pneumonia with representative pictures.


Summary The quantitative distribution and excretion of aminonucleoside-8-C14 was studied in normal and nephrotic rats. In the 8 hours following subcutaneous administration the normal rat excreted 65–70% of the dose in the urine, half of which was unchanged PA, and 15–26% in the feces. Despite being the target organ, the kidney contained less than 0.25% of the dose, while the liver contained considerably more. Nephrotic rats excreted much less of the radioactivity-total as well as in the form of unchanged PA. The decrease in excretion of total radioactivity was attributed to its retention in an expanded pool of body water characteristically seen in the nephrotic syndrome.

This paper employs Gabor transform to the analysis of speech signals. Speech signals were recorded under noisy conditions. The results of the analysis were compared with those obtained by employing short time Fourier transform (STFT). Gabor analysis gave, in general, a better spectral resolution as compared to STFT analysis of speech signals. Gabor analysis though had been applied to speech signals but is not yet as widely used as STFT analysis. It has, however, more potential for its application to speech processing than presently exploited. and The holds a wide to an to

about training for social professionals in Europe. The material for the book is rooted in the experience of the contributors, working both in their local contexts and collaboratively across national boundaries. The book therefore also provides some useful material about public attitudes, the place of minority ethnic groups in different societies, and political and professional responses in countries including Italy, Germany and the Netherlands, as well as Britain. Contributors are drawn from these countries and from the USA, and they often also have knowledge of other national or ethnic identities within their personal experience. The book is therefore rich in experiential perspectives. The theoretical underpinning of this book is valuable, not least because the literature cited extends beyond the English-language material usually available to British authors and also crosses disciplinary boundaries, since a number of writers come from pedagogic rather than social work backgrounds. The focus of the book – work with young people – might suggest that its relevance is limited to people working with this 'user group', and clearly much of the material (including suggestions for practical exercises at the end) will be particularly useful for workers and trainers in this field. However, it will also be of interest to others concerned with professional education and training, groupwork and European social work. In conclusion, the book demonstrates the potential for enriching our own understanding and practice that lies in collaborative work across national boundaries, and the value of interdisciplinarity in developing ideas and programmes for the education and training of social professionals. It is a welcome companion to Social Work and Minorities (Williams et al., 1998), one of the few other books currently assisting development of comparative knowledge and theoretical perspectives on anti-oppressive practice in relation to race and ethnicity in the particular field of social and community work policies and practice.


The purpose of this study was to investigate the effect of creative drama on the levels of shyness, self-esteem, and mental well-being in disadvantaged youth. This study was planned in a single group pretest-posttest design. 10 sessions of creative drama activities were held for each group by the drama-trained researchers approximately 120 minutes per week. The data of the study were collected by using the Personal Information Form, Coopersmith Self-esteem Inventory, Warwick - Edinburgh Mental Well-Being Scale, and Shyness Scale. After transferring the data to the computer-aided SPSS package program, the data were evaluated using percentages, averages and significance tests. While the Self-Esteem Scale average score was 59.846 ± 14.986, the Shyness Scale average score was 61.153 ± 15.032 and Warwick-Edinburg Mental Well-Being Scale average score was 51.096 ± 8.661 before the intervention, it respectively changed to 71.923 ± 13.430, 49.230 ± 12.267 and 55.384 ± 9.088 and these differentiations in all three dimensions were found to be statistically significant. It was observed that 10-week creative drama sessions increased the level of self-esteem and mental well-being of disadvantaged students as well as decreasing the level of shyness.
