related death for both men and women in the United States [1]. Colonoscopy with polypectomy has been proven to substantially reduce the incidence and mortality associated with the disease [2], but colonoscopy appears to be less effective in preventing right-sided colon cancers [3–6]. Studies have shown that interval colon cancers are almost twice as likely to occur in the right colon, and may represent a biologically distinct subset with regard to demonstrating higher rates of microsatellite instability and CpG island methylator phenotype [7]. Studies have also suggested that polyps with advanced histology are smaller in size, and more likely to be sessile in the right colon than in the left colon [8, 9]. Furthermore, the right colon is technically more difficult to examine during colonoscopy [10]. Repeat examination of the right colon to improve the detection of polyps is therefore considered. The repeat examination can be done in a standard forward-view manner, or the colonoscope can be retroflexed in the cecum and the right colon examined in a retroflexed manner. Retroflexion has the theoretical advantage of being able to visualize the back-side of haustral folds and flexures, mucosa that can be difficult to examine in the forward-view position. Retroflexion however is not always possible, because of colon anatomy, a looped position of the colonoscope, and operator inexperience; and it is also associated with a small risk of perforation [11].

The synthesis, crystal structure, crystal growth, and characterization of a new noncentrosymmetric rare-earth borate BiSr(3)(YO)(3)(BO(3))(4) are reported. BiSr(3)(YO)(3)(BO(3))(4) belongs to gaudefroyite type of structure and crystallizes in the polar hexagonal space group P6(3) (no. 173) with a = 10.6975(16) Å and c = 6.7222(12) Å. In the structure, the YO(7) polyhedra share edges to form an one-dimensional chain along the [001] direction. These chains are interconnected by the BO(3) group to construct a three-dimensional framework, leaving two kinds of channels for Bi atoms and Sr atoms together with BO(3) groups, respectively. On the basis of the powder second-harmonic generation (SHG) measurement, BiSr(3)(YO)(3)(BO(3))(4) belongs to the phase-matchable class with a SHG response of about 3 × KDP.


In this manuscript, we suggest a three-step iterative scheme for finding approximate numerical solutions to boundary value problems (BVPs) in a Banach space setting. The underlying strategy of the scheme is based on embedding Green's function into the three-step M-iterative scheme, which we will call in the paper M-Green's iterative scheme. We assume certain possible mild conditions to prove the convergence and stability results of the suggested scheme. We also prove numerically that our M-Green iterative scheme is more effective than the corresponding Mann-Green and Khan-Green iterative schemes. Our results improve and extend some recent results in the literature of Green's function based iteration schemes.


with error bars of 2 SD, the results may be seen in perspective (fig. 1, lower panel). The investigators described repeat testing for differences between the groups by Student's unpaired t test or by Mann— Whitney U test, and stated that they then confirmed the differences by analysis of variance or by Kruskal-Wallis. However , it is invalid to test repeatedly by Student's or by Mann-Whitney unless a difference between groups has first been shown by analysis of variance or by Kruskal-Wallis. The investigators' final assertion is unproven. They imply that a patient who has already had a pressor response to cannulation may have an exaggerated response to a further stimulus, and that this is the reason that high risk patients should receive local anaesthesia before cannulation. The investigators did not describe subsequent laryngoscopy, so do not know that a response would be exaggerated. Patients truly at high risk would almost certainly receive some prophylactic treatment before laryngoscopy, and "will never be included in the control group of an outcome study examining the efficacy of haemodynamic control at... intubation!" [2]. 1. Langham BT, Harrison DA. The pressor response to venous cannulation: attenuation by prior infiltration with local anaesthetic. Sir,—In the paper by Langham and Harrison on the pressor response to insertion of an 18-gauge venous cannula [1], the authors concluded that there was a significant response to venous cannulation, as judged by changes in mean arterial pressure (MAP) and rate-pressure product (RPP), which was obtunded by prior infiltration with local anaesthetic; they recommended that lignocaine should be considered before insertion of an i.v. cannula. There are several aspects of this paper which we would like to discuss further. First, we were not told in which arm cannulation took place. Presumably, it was into the arm opposite to that used for arterial pressure readings. Injection of local anaesthetic into the same arm might, theoretically, affect the neighbouring microvasculature and interfere with arterial pressure readings by digital plethysmo-graphy. Second, we were not told if the cannulation site was standardized. It is possible that bias could have occurred if Investigator 1 was free to choose a location for cannulation. The methodology described does not prevent Investigator 1 using a large antecubital vein for one group and a small ventral wrist vein for the other. Third, the reader is unable to determine if patient bias influenced outcome. What information was the patients given? Were …


The RHP Companion to Leaving Care is one of the most comprehensive publications I have come across so far on the subject of young people leaving state care. It contains a total of 21 articles from 30 authors covering a wide range of aspects of leaving care in the UK. This book offers a clear overview of the recent developments in the leaving care sector, both in terms of legislative and program supports. Drawing on the successes of various programs, The RCH Companion to Leaving Care sets out in clear terms a range of examples of what is considered to be good practice.


Much of General Practice education focuses on the need to practice Evidence-Based Medicine (EBM). Only in University Departments is access to the electronic databases and other electronic information needed to inform evidence-based choices made widely available. In The Doctor's Desk project we have tried to place the tools that enable the practice of EBM alongside the GP's computer system, as well as provide a conduit for electronic messaging.
GP computer suppliers have previously provided global solutions for their practice clients. These have tried, alongside their clinical databases, to provide other applications, some of which have been indifferent. Most GP clinical software is hard to integrate with office software such as word processors and spreadsheets, and electronic clinical measuring devices like ECG and Spirometry. Communication with hospitals is developing slowly, but currently most GP systems can only integrate with clinical software text messages.
The Doctor's Desk project integrates electronic information sources on a single computer screen. These include information databases, email and access to clinical information in both general practice and hospital computer systems. This system operates within NHSnet, to which the government has pledged to connect all GPs by 2002. We show in this pilot that not only is it possible to provide the tools of EBM and communication alongside any practice clinical system, but also that its provision promotes its use.
GPs should regard their clinical software as an application just like any other. They should look for ways of integrating it with other software they may wish to run, bearing in mind only that the fewer the number of stables that software and hardware are obtained from the easier it will be to achieve this integration.


The explicit author collaboration and tacit author collaboration are two parts of the author collaboration in scientific research. The article uses the social network analysis method to study the explicit author collaboration in the semantic retrieval field in China, then, excavates the tacit author collaboration in the semantic retrieval field in China based on keyword coupling. In this way, the research result can provide important basis for knowledge exchange and information transfer between authors.


One of the main challenges faced by autonomous underwater vehicles (AUVs) is their navigation capability. A commonly used navigation strategy is dead-reckoning inertial navigation integrated with a seafloor-tracking Doppler velocity log (DVL). The disadvantage with this technique is the un-bounded accumulation of errors during operation. Terrain-aided navigation (TAN) has been deemed as a viable approach to compensate for dead-reckoning navigation errors. This type of navigation uses a predefined map of the seafloor and estimates the position of the vehicle on the map by matching the map to bathymetry measurements from vehicle sensors.The physical limitations of an AUV platform places restrictions on what kind of sensors can be used, such as weight, size, resolution, power consumption and accuracy. For this reason, a dedicated TAN-sensor is undesirable. In addition to a DVL, many vehicles make use of a forward-looking sonar (FLS) for obstacle avoidance. In this work, we implement a particle filter-based TAN algorithm using DVL altitude data fused with FLS information. We simulate TAN navigation for several different types of FLS, and compare the navigation performance. In general, we find that navigation performance improves with the number of sonar beams. This is expected, as a more complex sensor means more information is gathered and input to the navigation. However, we also find that a configuration using just three single-beam echo sounders performs as well as a proper multibeam FLS.The results show that the multiple single-beam echo sounder configuration is an interesting solution due to its high accuracy during the navigation while retaining a low impact on the platform dynamics and power consumption.


Economic factor should not be a major concern in the strategy of ICU treatment abandonment.We can come to common understanding about treatment abandonment for cerebral death\,vegetable condition and terminal patients on the basis of respectance to science and intellect,respectance to the value and significance of terminal lives,and pursuing for fair distribution and useful application of social resources.So far,it is important to establish related policies and laws to ensure reasonable implementation of ICU treatment abandonment.


At present,with the development of flooding,most of the oil fields have been into the high water cut or high water cut stage,one after another been in Phase II or Phase III oil production statge,the situation of flooding is becoming more serious,oil field exploitation of the latter part of the difficulty is increasing more and more.The resistivity of formation water of water-flooded zone is not only important to evaluate the water level on the basis of the parameters,but also be the difficulty of constrainting of the reservoir evaluation.To strike a water-resistance must be fully integrated development of water at this stage,pay attention to the changeing in water type and salinity in order to achieve better geologic effect.This article is supplying references for providing the model of oil remaining through accomplishingthe plate of resistivity of formation water from Gasi oil field information.


The origin of electron transport noise whose power spectral density is inversely proportional to the frequency f has been realized after 80 years of attempts. Here we give its conceptual explanation that has required a sequence of five ideas and corresponding results: 1) The reduction of the nonlinear Boltzmann equation with electron-electron (e –e) interaction to a Fokker-Planck (denoted as e –e FP) equation containing two electron collision frequencies ν1 and ν2; 2) the application of the e –e FP to materials and its-steady state solution that depends on ν1(υ), ν2(υ), and the square a2 of the acceleration a = eE/m; 3) the steadystate solution of the e –e FP equation becomes similar to the Fermi-Dirac distribution function if a2 is considered as mainly due to the zero-point field (ZPF) of quantum electrodynamics (QED) or, realistically, of stochastic electrodynamics (SED); 4) in this δυ range the e –e FP is similar to the usual FP solved by Stenflo when ν (υ) ∝ 1/υ. It is just because of aZPF that for any conduction current there is always a small interval δυ for the electron speed υ where ν1 ∝ ν2 ∝ 1/υ, condition that is at the threshold of runaways. The relevant time-dependent Green solution of the e –e FP equation decreases as τ–e with e < 0.006. The consequent power spectral density S (f) turns out to be ∝ 1/f1–e in an indefinite medium. Our S (f) also depends on the electrons concentration N and excellently fits the experimental data; 5) In a finite sample the memory or a fluctuation is preserved beyond the electron transit time because the transmission of information is mainly due to e –e interactions and to the diffusion coefficient that diverges at the threshold of runaways. A pimple (due to fluctuation) in the distribution function on the electron speeds is almost crystallized, decaying as τ–0.005 without any cut-off at the transit time.

Suggests an algorithm that increases the reservation success probability for bursty traffic in high speed networks by adding flexibility to the construction of the routes. The algorithm is simple enough to be implemented by cheap hardware. It causes no additional delay to packets that use the original route, and a very small delay to the packets that are rerouted. In addition, the presented algorithm has a minimal communication overhead due to the local nature of its work. Two high-speed network models are considered: source routing and ATM.


There has been a tight correlation between the change of the cement rotary kiln carrent and operation conditions, such as the kiln thermal condition, the thickness of the crust, the kiln tyre collapse and so on. Considering the different fractal characteristics that cement rotary kiln current signal exhibit in different conditions, this paper has study on the generalized fractal dimension of kiln current signal under different working conditions as the characteristic parameter. The levels and trends of rotary kiln current and working condition will be identified by computing the maximum correlation coefficient according to the generalized fractal dimension of detected signal and of cement rotary kiln current under different working condition.


This brief considers a robust finite-time output feedback control scheme for the tracking problem of flexible-joint (FJ) robotic systems subject to unknown matched and mismatched time-varying disturbances. For this purpose, a novel dynamic terminal sliding mode surface is firstly constructed base on a sliding mode observer. Then, a continuous finite-time control scheme is developed to cope with these disturbances. Besides, the proposed controller guarantees the finite-time convergence of the closed-loop system and requires only the measurements of link positions. Finally, a two-link FJ robot as an example is provided to illustrate the effectiveness of the proposed control scheme.


This work presents the first enantio- and diastereoselective assembly of multi-layer folding targets through asymmetric catalytic C-C bond formation. Pd[(S)-BINAP]Cl2 was found to be an efficient catalyst for Suzuki-Miyaura coupling between phosphinyl bromides and benzo thiadiazole boronic esters for this asymmetric assembly. The resulting chiral multi-layer folding framework was unambiguously determined by X-ray structural analysis showing a nearly parallel pattern of three layers and quasi-syn and -anti configurations. Good to excellent diastereo- and enantioselectivities (up to > 20:1 dr and > 99:1 er) have been achieved.


Background: Neuroendocrine neoplasms (NENs) are a subgroup of poorly characterized rare tumors with challenging management. Identification of clinically useful biomarkers for patient stratification and treatment tailoring is urgently needed. This study proposes the use of near-patient models based on autologous extracellular matrix (aECM)-scaffolds and zebrafish (ZF) xenografts integrated with next generation multi-omics analysis for the phenotype and genotype mapping of NEN cells. The aim is to uncover molecular signatures associated with disease aggressiveness and to detect oncogenic drivers for targeted treatment.
 Methods: Primary tumor cells isolated from surgical specimens of NEN patients were cultured in aECM scaffolds or injected into ZF embryos. Autologous ECM-scaffolds were synthesized starting from the patients' matrices and recellularized with primary cells derived from matched patients. In aECM scaffolds we evaluated tumor cell proliferation and neuroendocrine differentiation. In ZF we evaluated cell angiogenic ability and distant invasiveness. For each primary culture, we performed exome and transcriptome analysis of the original tumor tissue compared to the matched healthy counterpart.
 Results: We demonstrated that ZF xenografting faithfully recreates the behavior that tumor cells exhibit in patients. Specifically, we derived a primary culture from an ileal grade 1 neuroendocrine tumor from both the primary and the metastatic lesions. When injected into ZF embryos, cells derived from the primary tumor displayed low invasive ability with a metastatic rate of only 23%. Conversely, cells derived from the metastatic lesion were able to invade the ZF circulation and form distant metastases in 79% of embryos. Consecutively, we derived three primary cultures of neuroendocrine Merkel cell carcinoma (MCC). The 3 MCC cultures into ZF embryos showed high aggressiveness with metastatic rates of 81%, 50% and 64%. For one culture, angiogenic ability was also observed. RNA-sequencing of these aggressive MCC specimens highlighted the involvement of the following pathways: ECM remodeling, TNF-ⲁ and PI3K-Akt signaling, epithelial-mesenchymal transition and regulation of apoptotic processes. Next, we demonstrated that aECM-scaffolds morphologically resemble a native tumor tissue, and tumor cells, once seeded on them, preserved the expression of neuroendocrine markers.
 Conclusions: Here we developed innovative neuroendocrine tumor models that are expected to generate new knowledge on the disease molecular determinants. All identified genomic and genetic alterations will be correlated with the clinical outcomes of enrolled patients, to validate their clinical significance and to ultimately introduce a biomarker-based approach for NEN patients.

The cases of feminicides in Brazil are old and recurrent, and the social discourses that surround them continue to be worrisome, because they still and currently revolve around the guilt of the woman (victim). The objective of this work is to discuss how the discourses are inserted and maintained in the systems of a chauvinistic and patriarchal society that support the guilt of women. The corpus of this work is composed of comments (statements) by internet users who follow the page @anapolis.noticias_ on the social network Instagram that were published in two news stories this year. For this, we resorted to the theoretical postulates on discourse and power of the French philosopher Michel Foucault.


The FID has undertaken as a matter of urgency to prepare a scheme which may drastically alter the tables of the UDC. Although the full proposals have not yet been decided, the information that is available indicates that they will significantly affect existing users.


An artificial neural multi-layer network has been developed for predicting the mass transfer coefficients in the liquid and gas phases for the gas absorption (CO2) from the air using an absorbent - water. For the development of neural network the unobservable parameters of the packed absorber were calculated. The obtained results can be used to model an extensive class of chemical engineering processes with the possibility of formalizing the calculation procedures.


The speech of the worker Peter Alekseev, delivered on March 9, 1877, at the famous trial of "the fifty," occupies a sensitive position in the debate concerning the contributions and participation of workers and peasants in the Russian revolutionary movement. Between 1877 and 1917, the speech was reprinted more than twenty times by both populists and Marxists, thus providing the Russian free press with one of its classic publications. Adam Ulam has recently questioned Alekseev's authorship of the printed text on two grounds. First, Ulam considers the printed speech too polished to have been written by a worker.

Key-words: Tetralophodont /Mastodonts - Teeth - Lower Langhian Vb - Evolution - Origin of tetralophodont structure

This study deals with maslodonl leeth found near Lisbon in Lower Langhian (lower Middle Miocene) flUViatile. feldspathic sands (Vb
division).
Conclusions are as follows:
I. Tetralophodont molars (even if at a still prImitive stade of the tetralophodont condition) do exist at least since lower Lanahian times. and not only since late Middle Miocene as wase previously known.
2. Tri- and letralophodonl structures may (and indeed do) coexist in the same individual: such examples do nol correspond to transitional forms. bUI instead to a mosaic of juxtaposed characters (however this does not mean there are no transitional forms in other instances).
3. So these structures coexisted in a population not yet genetically separated beyond fertile cross-breeding. i.e. beyond species' level.
4. Origin of the tetralophodont molar was due to some mutation (s). but without crossing species' limits and even more genus'ones.
5. At this times probably soon after the first appearance of tetralophodont mutants. animals with such characters were a small but signifiant minority among the population (17 'k if accounl is laken on D4 's: only 2'k after M;s).
6. There was nOI Ihen any direct and clear correlation between number of lophs (transversal crests) and tooth size, even if the increase of such number goes along with length's increase.
7. Dimensions (length in special) in tetralophodont teeth tend to exceed those in - normal- trilophodont teeth. this being particularly clear in D4. even if there is no clear distinction: the situation is quite the same. maybe less marked, with the M2.
8. According to the preceding conclusions there are no reasons to segregate different taxa among such mastodont population on the grounds of the presence in D4, M1 and M2 of 3 or 4 crests (this character being regarded as diagnoslic of' the genus Tetralophodon).
9. On the contrary, if any natural (in biological sense) classification is disregarded and a morphological parataxonomy is adopted there should be considered both Gomphotherium angustidens and Tetralophodon sp.: however this is absolutely not our opinion.


Respective British governments in Bermuda, the Bahamas, Jamaica, Antigua, St. Lucia, Trinidad and British Guiana have all agreed to US bases and the land to be used. Although discussions of jurisdiction and administration will need to be agreed, that these discussions should take place in London, and that construction can being before lease agreements are signed except St. Lucia where a delay until June 1941 is required.

. Learning is nowadays a continuous intellectual readiness to be able to cope with the current needs of the world of work. Students' knowledge must be adapted accordingly and they must be capable of continuous development throughout their lives [8]. Changes in teaching-learning habits have already been observed at the beginning of the 21st century and those involved in education need to adapt to these changes with the appropriate transition to digital education what is more important today than ever before. We asked our teacher-candidate students in an online questionnaire at the beginning and at the end of the "Teaching Methods in Mathematics" course. Our non-representative survey provided valuable data for course development. The aim of the survey was to find out students' perceptions of the methods and tools they had learned in education. In the questionnaire at the beginning of the semester, we inquired our students about the types of work and methods they were familiar with, and then they gave their opinions about the different ICT tools, educational programmes and applications and how they were used. At the end of the semester, we interwieved them again whether they still held similar views on the subject or they had managed to change their views during the course.


The invention relates to a fixing structure for a faucet 10 to secure the faucet on a sink countertop 2. The structure comprises a housing 11, a pull-out spray head 12, a mixing valve 13, and a water supply set 14. The water supply set includes a cold-water inlet pipe 141, a hot-water inlet pipe 142, and a mixing outlet pipe 143. The structure also comprises a positioning device 100 having a base 20 with a peripheral wall 21, a bottom wall 22, and an aperture 23. The bottom wall has a limiting face 24 and at least one orifice. The limiting face has a channel (242 figure 5), two stop posts (25 figure 4), and an abutting face (222 figure 4). Two screw rods (30 figure 4) extend out of the hole and are rotated above the base. Two clamping blocks (40 figure 4) are screwed onto the two screw rods, and are limited by the two stop posts. When the two screw rods are rotated, the two clamping blocks move upwardly to abut a bottom end of the sink countertop.


Point of Interest (POI) recommendation is to use the user check-in data in location-based Social Networks (LBSN) to predict the next Location that the user will visit. With the rapid development of LBSN, users' check-in information (rating information, geographic location, check-in sequence, social network, etc.) has become more and more accessible. How to effectively fuse and model these multi-source heterogeneous data is crucial to personalized POI recommendations. This paper presents a POI recommendation model based on improved factorization machine and Bert. By integrating social influence on the basis of factorization machine, Bert was used to extract the check-in sequence features. Experiments on real data sets show that our model performs better than the traditional POI recommended model.


PurposeThe purpose of this paper is to analyze the impact of social and economic exchange relationships on organizational commitment in line with the mediation effect of organizational trust.Design/methodology/approachIn order to test the hypotheses of the study, a survey was conducted on a sample of 213 employees who were working at manufacturing companies in Turkey.FindingsThe findings of the study reveal that both dimensions of the exchange relationship positively affect organizational commitment and these links are mediated by organizational trust.Research limitations/implicationsThe study provides reliable scales to measure the social and economic exchange relationship between employees and employing organizations. Although the sample of the study was relatively small and drawn from a single country, the Cronbach'sαvalues of scales were obtained above the recommended threshold value.Practical implicationsOrganizational leaders might adopt an exchange perspective to build a trustworthy relationship with their employees. Developing such a mindset is very important at an employment structure, which has become highly flexible and contingent during the last decades.Originality/valueThe study attempts to distinguish the twofold nature of the exchange relationship in organizations based on a theoretical model to reveal the impact of each dimension on organizational level outcomes in conjunction with the mediating role of trust. In doing so, the study contributes to the literature by incorporating social and economic exchange in a holistic view as well as defining each dimension in a broader sense by including some employee-related challenges of business organizations such as diversity, social responsibility, leadership, ethical culture and so on.

OBJECTIVE
It was of interesting to synthesize some new 5-imino-4-thioxoimidazolidin-2-one derivatives with different halogenated and alkylated aromatic substituent at N-(1) and N-(3) and evaluation of their expected antibacterial and antifungal activities.

METHODS
New 5-imino-4-thioxoimidazolidin-2-one derivatives were synthesized through the reaction of different halogenated and alkylated N-arylcyanothioformamides with halogenated and alkylated aryl isocyanates.

RESULTS
5-Imino-4-thioxoimidazolidin-2-ones were obtained in high yields with excellent purity. The activities of imidazolidines as antibacterial and antifungal agents were studied. Some of imidazolidine derivatives displayed significant antibacterial and antifungal activities.

CONCLUSION
5-Imino-4-thioxoimidazolidin-2-ones were obtained in 77-90% yields with excellent purity. The antibacterial and antifungal activities suggest that some of the imidazole derivatives possess significant antimicrobial activity against B. subtilis, K. pneumonia and C. albicans and moderate activity against S. aureus.


SS304 steel is used in most of the engineering structures and components wherever high strength is required. SS304 steel has good corrosion resistance property but it will not withstand the combined effect of corrosion in the presence of stress which is reported in our earlier study. For this case the conventional methods like coatings or platings will not withstand for a longtime and it will peel off over a certain period of time. Eventhough oxide layer formed on the surface of SS304 will also lead to break due to the presence of load which provides path for a corrosion particles makes its impact in depth of the specimen. Inducing micropatterns on the surface may stand as an effective solution to suppress corrosion in the presence of stress for a prolonged time period. In this work micropatterns in the form of grooves was formed on the surface by means of Electrical Discharge Machining Process (EDM) and characterised using 3D optical profilometer. Wetting and corrosion study was conducted on plain and micropatterned surface using high speed camera and electrochemical workstation to reveal the relation between them. Micropatterned surface shows considerably less wetting and better corrosion resistance property when compare to the plain surface.

The Chinese table tennis team has long been outshining rivals over the years. Since 2000, the International Table Tennis Federation (ITTF) has launched a series of reforms aiming at saving the global table tennis industry. Since the previous reforms were not thorough enough, they were basically halfway resolved by the powerful Chinese team. Instead, the Chinese team grew stronger! However, the ITTF's 40+ plastic ball reform has moved the real thing, which weakens the lethality of the Chinese team at the cost of limiting the "dynamic element" (the "rotation" factor in particular) and risking technique regress, the great impact force is beyond our envision! The author makes an in-depth analysis of the core technology and non-core technology of 40+ athletes based on the principle of 5 elements of table tennis competition, pleading for countermeasures of the adverse effects brought by the "falling spot" in exchange for "rotation", "tactics element" improvement and "technique element" compensation, and providing a reference for the Chinese team to step out of the dilemma.


Two experiments were carried out in order to compare chopped whole sugar cane fed immediately after chopping, and the same sugar cane fed 24 hr after chopping. In the first experiment (112 days) which was carried out during the rainy season, the other comparison was level of wheat bran (1000 or 500 g/d). However, in the second experiment (63 days) carried out in the dry season, the additional comparison was access or no to a mixture of molasses containing 10% urea. The experiments were carried out with 24 Zebu bulls and the design was a 2 x 2 factorial with two replications (3 bulls per group) in each of the two experiments. There were no significant differences which could be attributed to the affect of pre-fermenting the sugar cane in either part of the experiment (320 vs 291 g.d in the first part; and 414 vs 411 g/d in the second part, for fresh and pre-fermented cane respectively). The results showed no significant differences in the first part of the experiment due to the level of wheat bran (296 vs 314 g/d for 500 and 1000 g/d of wheat bran respectively); however, there was a significant increase due to the molasses/urea both in liveweight gain (557 vs 267 g/d; P <.002) and in conversion (9.95 vs 19.7 kg/kg of growth; P <.001). The respective voluntary intakes were sugar cane 14.2 and molasses .93 kg/d; and sugar cane 15.7 kg/d for the treatment without molasses. It was concluded that pre-fermentation of the sugar cane had no effect on animal performance under the conditions in which this experiment was carried out, but that there was a highly significant improvement when the animals also had access to molasses containing 10% urea.


We have taken a systematic approach to the clean production of functionalized aromatic amines, adopting the hydrogenation of o-chloronitrobenzene (o-CNB) to o-chloroaniline (o-CAN) as a case study. We tested a laboratory-synthesized Au/TiO2 catalyst against a commercial benchmark (Pd/C). Both catalysts exhibited nanoscale (1–9 nm)-supported metal particles (dTEM = 4.0 nm (Au) and 5.4 nm (Pd)). In batch liquid phase operation, Pd/C was nonselective, generating aniline and nitrobenzene as undesired byproducts, where elevated PH2 (5–12 atm) increased the rate and o-CAN selectivity (to 86%). In contrast, Au/TiO2 promoted exclusive o-CAN production regardless of PH2 but at a lower rate. Reaction exclusivity extended to (ambient pressure) gas phase continuous processing with 100% o-CAN yield and catalyst stability up to 140 h on-stream. A switch from batch to continuous operation was accompanied by an increase in projected o-CAN production capacity (5 × 103 → 86 × 103 kgo-CAN kgAu–1 year–1). Water (as o-CNB car...


This work compares UV-fluorescence (UV-F) and UV-absorption (UV-A) as detection methods in the analysis of coal and petroleum-derived materials, using size exclusion chromatography (SEC). A UV-F spectrometer that was equipped with a flow cell was connected in series to an SEC chromatograph with a conventional UV-A detector. Samples were examined via SEC, using both UV-F and UV-A detectors that were operating in tandem. They included asphaltenes from heavy petroleum residues and three fractions of a coal tar pitch obtained by solvent solubility separation. The chromatogram of the lightest fraction of the coal tar pitch (the acetone solubles) showed a single peak, with close agreement between both detection systems. The rest of the samples showed an early-eluting peak that corresponded to material excluded from the column porosity, in addition to a retained peak. UV-F showed little sensitivity to material eluting under the excluded peak in any of the samples and also was less effective than UV-A in detectin...


Abstract: In Ohio, agricultural channels have been constructed or modified to transport surface runoff and subsurface drainage away from agricultural fields. The development of depositional bars, or benches, in these agricultural channel systems has been a focus of maintenance activities. Objectives of the reported study were to: (1) determine if there was a relationship between inset channel geometry, as defined by its benches, and geometry predicted by regional curves that relate bankfull geometry to drainage area; (2) evaluate the effect of channel geometry on bed material particle size distribution; and (3) determine if the particle size distribution of bench materials was related to depth from the surface and position on the bench. The study was conducted on low gradient ditches that are headwaters of the Mississippi River and Lake Erie. An analysis to determine the extent of bench and inset channel formation was undertaken using 0.15 m (0.5 ft) resolution panchromatic digital orthophotos. Geomorphology measurements were made at 13 sites, and a 61 cm (24 in) long split-spoon sampler, with a 7.6 cm (3 in) inner diameter, was used to extract cores from the benches at each site. About 59% of the assessed channels showed inset channel development and bench formation. For 12 of the 13 sites, the bankfull dimensions of the inset channel were consistent with regional curves. All benches showed fining of materials with distance away from the inset channel. It was concluded that benches evolve much like floodplains that build because of overbank accretion. The results will be helpful in determining alternative strategies for improving the drainage function of these systems while enhancing ecological habitat and water quality.

What follows are my comments on the nal draft of the CCSSI Core Mathematics Standards. There are a number of standards including, but not limited to 1-OA(6), 2- OA(2), 2-NBT(5), 3-OA(7), 3-NBT(2), 4-OA(4), 4-OA(6), 4-NF(1), 4-NF(2), 5-OA(3), 8-G(2), 8-G(4), F-LQE(5), G-SRT(4) that are completely unique to this document, and most of them seem problematic to me. I have repeatedly asked for references justifying the insertions of these or similar standards in previous drafts, but references have not been provided. Consequently, to my knowledge, there is no real research base for including any of these standards in the document.


Cross-sectional (contemporaneous) forecast reconciliation of a linearly constrained (e.g., hierarchi-cal/grouped) multiple time series. The reconciled forecasts are calculated either through a projection approach (Byron, see also and and Wickramasuriya 2019), or the equivalent structural approach by Hyndman et al. (2011). Moreover, the classic bottom-up approach is available.


ABSTRACT Undergraduate students can develop different bodies of knowledge by engaging with members of their family, university, and community. In this study, we investigated how undergraduate students used the knowledge, skills, and resources they gained in class to engage with their local communities through the creation of documentary films as part of an undergraduate course assignment. We employed funds of knowledge as a theoretical lens to understand how students utilize their academic knowledge in community contexts, and how students accumulate funds of knowledge within these contexts. The findings demonstrate that community-based knowledge was transmitted through a food discourse, which in turn informed the students' academic knowledge. What is highlighted is the dialectical relationship between knowledge developed through community engagement and those gained through academic contexts.


Objective The present study was aimed to investigate the appropriate and reliable methods for isolation, culture-expansion of canine bone marrow mesenchymal stem cells (MSCs). Methods The bone marrow mononuclear cells were isolated from 15 -20 ml canine bone marrow aspirates, by using density gradient centrifugation with 1.068 g/ml or 1.073 g/ml separating mediums. All cells were cultured at 37℃ under5% CO2 atmosphere in DMEM supplemented with 15% fetal bovine serum, 100 U/ml penicillin, 100 μg/ml streptomycin, and 25 μg/ml amphotericin B. The medium was replaced every 2 or 3 days. The MSCs were identified by special cellular surface antigens and pluripotent differentiation potential. Results With the density gradient centrifugation method, the mononuclear cells were successfully isolated, and the Nycoprep 1. 068 group could obtain more purified monocytes. The adherent cells proliferated quickly at a doubling time of 24 hr. When the cells were confluent, the morphology of adherent cells was spindle-shaped, small and arranged like pectinate. The characteristics of proliferation and morphology did not change after 8 passages, and there was no evidence of spontaneous differentiation. The expanded adherent cells were positive for SH2, and negative for CD45 surface antigen. Under the induction of chemicals, the MSCs differentiated into cardiomyocytes, adipocytes and osteocytes. Conclusions The mesenchymal stem cells from canine bone marrow could be isolated, cultured and expanded in vitro through the density gradient centrifugation with Nycoprep?1.068 and adherent cell cultivation. These cells showed the characteristics of mesenchymal stem cells, with self-replenishing ability and pluripotent differentiation potential.

A series of rapid and inexpensive methods to produce elastically soft sensors and circuits in minutes using a CO2 laser (10.6 μm wavelength) are introduced. These soft‐matter electronics are composed of laser‐patterned films of conductive poly(dimethylsiloxane) (cPDMS) and liquid‐phase gallium–indium (GaIn) alloy embedded in a thin sheet of soft silicone elastomer. Direct laser patterning eliminates the need for photolithography, replica molding, and customized inkjet or microcontact (μCP) printing, and allows conductive traces of cPDMS and liquid GaIn to be rapidly integrated into a single soft‐matter circuit. The versatility of this fabrication method is demonstrated by the production of a variety of electrically functional soft‐matter sensors and circuit elements that contain features with >150 μm planar dimensions. It is postulate that in the case of GaIn alloy patterning occurs when the recoil force of the escaping vapor exceeds the liquid's surface tension. This mechanism exploits the unique "moldability" of liquid GaIn alloy, which forms a surface oxide of Ga2O3 that allows the patterned film to maintain its shape.

Abstract This paper is concerned with high-dimensional asymptotic results for W- and Z- rules when the sample size N and the dimension are large. Firstly, we give a unified location and scale mixture expression of the standard normal distribution for W and Z statistics. Then, the EPMCs (Expected Probability of Misclassifications) of W- and Z- rules are obtained in expanded forms with errors of It is pointed that Z-rule has smaller EER (Expected Error Rate) than W-rule when the prior probabilities are the same, neglecting the terms of Further, asymptotic unbiased estimators are proposed for the EPMCs and the EERs of W- and Z- rules. Accuracies of our asymptotic results are checked numerically by conducting a Mote Carlo simulation.


TFTR performance has surpassed many of the previous tokamak records. This has been made possible by the use of tritium as fuel for DT plasma discharges. Stable operations of tritium systems provide for safe, routine DT operation of TFTR. In the preparation for DT operation, in the commissioning of the tritium systems and in the operation of the Nuclear Facility several key lessons have been learned. They include: the facility must take the lead in interpreting the applicable regulations and orders and then seek regulator approval; the use of ultra high vacuum technology in tritium system design and construction simplifies and enhances operations and maintenance; and central facility control under a single supervisory position is crucial to safely orchestrate operational and maintenance activities.


Some of the essays (e.g. Heindl, Chastain), informative and interesting as they are, draw heavily on their authors' previously published works. However, taken together there is enough in the essays on the social dimensions of the revolution, especially the position of small farmers in different regions, the relation between social and national demands, Austroslavism, and the formation of national movements and national identities, to reward readers. Austroslavism, the idea of a democratic national federalism, usually is seen as an attribute of the Czech national movement, but it is treated in several essays (Kolejka, Makowski, Granda) in a much broader sense. The idea of Austroslavism as used by different Slavic ethnic groups in the Habsburg Monarchy was both supranational and national. Their programs of federalism were designed to secure the position of each of them in a reorganized empire. National ideologies, therefore, were an integral part of supranational Austroslavism and loyalty to the Habsburg Monarchy and dynasty was conditioned on the nationalitites realizing their national aspirations. The essays, as a whole, also emphasize that national movements are not simply the product of elites, but depend heavily on local activists and specific social conditions. Even more they show that the construction of national identity is not a discrete process of internal development, but that it has an important element of negotiation with another nationality, sometimes more than one. The volume concludes with an extremely useful 45-page bibliography consisting of 881 titles compiled by Eckhard Hubner (Kiel). The bibliography comprises mainly works-surveys, documentary collections, monographs, and scholarly articles-on those nationalities that were part of the Habsburg Monarchy and covers all aspects of the revolution for each of them. The bibliography will prove useful for all those interested in the 1848 revolution in a broad comparative sense or have a narrower interest in a particular nationality or political figure. Much the same can be said for the volume as a whole. It will prove useful to historians undertaking research on the "springtime of peoples" in East Central Europe.


Integrating evaluation initiatives in organisations as part of routine operations to support organisational learning and development can be difficult; extant literature lacks detail on the factors enhancing sustainability. This article presents research undertaken with evaluation advocates attempting to embed evaluation in their Australian non-profit organisations. The research involved interviewing seventeen participants, four of whom also were the focus of organisational case studies. The researchers used social interdependence theory to understand participants' strategies for embedding evaluation and found that some elements of cooperative teamwork were more prominent than others. Participants in high hierarchical positions, or those who had influence, worked intentionally and incorporated strategies that aligned with all five elements. Examples of those strategies and their use in context presented herein may help leaders and internal and external evaluators increase the likelihood of embedding evaluation in organisational systems.


Acetic acid is one of the most important carboxylic acids which is used in many reactions, including the synthesis of acetic esters. Because of industrial and environmental advantages, the separation of acetic acid from dilute aqueous solutions has recently received much attention. In this study we investigated liquid-liquid equilibrium of a ternary system consisted of water+ acetic acid+ organic solvent at various temperatures. In this study, various thermodynamic models (Non-Random Two-Liquid (NRTL) and Universal Quasi-Chemical (UNIQUAC) models) were used to predict the composition of component in aqueous and organic phases. In these models, intermolecular interaction were considered as a binomial function of reverse temperature. The parameters of two models were determined through the optimization of an objective function. Root mean square deviations of the NRTL and UNIQUAC models to predict the composition of the components in the ternary mixture of water+ acetic acid+ organic solvent were 0.0273 and 0.0422, respectively.


Popcorn (Zea mays everta) is a popular snack food and very appreciated in Brazil, presenting higher aggregate value when compared with field corn. The aim of this study were to identify superior inbred lines and single crosses hybrids (SH) for popcorn traits, as well as the prediction of the performance of untested single cross hybrids. Sixteen maize inbred lines were crossed in a 9x7 partial diallel, but it was possible to evaluate 47 single crosses in two distinct locations. Predicted genetic values, diallel analysis and the prediction of untested HS were performed by mixed models. Deviance effects for treatments x locations were considered non-significant (p>0.05) for grain yield (GY) and popping expansion (PE), showing an average performance from the HS in the locations. Inbred lines P5-1, P3.3T, GER-P3, P9-1, P12-2 and GER-P12 were selected considering the general combining ability, and should be used for obtaining superior genotypes. Based on the non-additive effects, the single hybrid P3.3T x GERP-P12 was selected for grain yield and popping expansion, and could be exploited in future trials. Neither of the untested single crosses showed desirable performance for grain yield and popcorn expansion.


Stress commonly associated with today's daily life has quite varied effect on pregnant females. Stress also affects general well-being of an individual but in pregnancy it is affecting two lives: the womb bearer and the one residing inside it. There is a steady rise in complications due to stress in pregnancies leading to increased rate of abortions, pre-term deliveries, PIH, GDM and IUGR in fetus. It also influences the neural development of the fetus causing adverse effects in later life.


In this paper,growth performance of 12 provenances of Betula luminifera from five provinces in south-west China were investigated when 8 and 20 month old,to study their genetic variation and preliminarily select prior provenances of this species in south-west part of Guizhou Province.The result showed that there existed significant differences among and within provenances for height and base diameter at the two ages,and growth variations within provenances were much higher than those among provenances.Heights were in significant positive correlation with base diameter at both ages.No significant relationship were found between growth traits and climate and geographic factors of provenance localities when 8 month old,while at age of 20 month,height and base diameter were in positively significant correlation with longitude,height negatively significantly correlated to altitude,and base diameter positively to mean annual rainfall.Three prior provenances,all from Guangxi,were preliminarily screen out mainly based on height at age of 20 month,which were suitable to develop in southwest parts of Guizhou.These findings will be contributed to further breeding studies and plantation development of this species in southwest parts of Guizhou and surrounding areas with similar environment.

Introduction: Physiologically, von Willebrand Factor (VWF) recruits platelets to sites of injury by binding to exposed collagen and platelet GPIbα, particularly at sites of high shear. VWF is critical to hemostasis, since complete deficiency leads to bleeding as severe as hemophilia. Conversely, VWF plays a key role in arterial thrombosis, as in myocardial infarction and stroke. Despite being an attractive therapeutic target, no agents directed against VWF are currently available. Our group is testing an RNA aptamer that blocks VWF binding to GPIbα as an antithrombotic. We have previously shown that leukocyte influx and cutaneous healing are impaired in a mouse model of hemophilia. We have also found that wound healing is delayed in mice given target specific oral anticoagulants. The purpose of the current study was to determine whether inhibiting VWF would similarly impair wound healing. Methods: We used C57BL/6J mice administered vehicle or VWF aptamer. At the dose selected, aptamer prolonged the saphenous vein bleeding time for the expected 10 day healing period. Healing was assessed in a skin punch biopsy model. Wound size was measured daily, and following sacrifice the wound area harvested for histology. Inflammation (in the absence of tissue injury) was induced by topical application of cantharidin for 24 hours, followed by tissue harvesting. Results: The in vivo efficacy of the aptamer was verified, since bleeding remained prolonged to a level slightly less severe than hemophilia at the end of the experiment (10 days after wounding). There was no difference in time to healing between control and aptamer-treated mice, with all wounds healed at 10 days. There was also no statistically significant difference in wound size at any time. Cantharidin induced a similar level of cellular influx in treated and control mice. Aptamer-treated mice exhibited a slight amount of inflammation-induced hemorrhage, though not the gross hemorrhage observed in thrombocytopenic mice. Conclusion: Inhibition of VWF activity does not delay cutaneous wound closure, despite inducing a severe hemostatic defect. Compared to other antithrombotic strategies, an aptamer against VWF could avert some undesirable side effects on host defense and tissue repair.

The structure of an adsorbed polymer layer in equilibrium with a dilute good solvent is considered theoretically. It is shown that under saturation conditions the tails of the polymer chains give an important contribution to the monomer density profile in the outer layer away from the wall: the tail contribution dominates over the loop contribution in the region aN0.5 < z < aNν, where z is the distance from the wall, a the link size, and ν the Flory exponent. The characteristic layer thickness is thus determined by the tail properties.

By analyzing the relationship between water and architecture, the paper lists five aspects namely overall concept, circulation, function, space and landscape, in which the water context guides and decides the design process and outcome.


Indonesia is the largest archipelagic country in the world, with two third of waters containing large marine resources. However, the coastal and marine resources have not been optimally utilized due to the limitation of Spatial Zoning Plan for Coastal and Small Islands (RZWP3K). In addition, there were many institutions which produce thematic maps of the coastal and marine resources (MGI) using different basemap, standard and technical specifications. Hence, same thematic maps provide different information. For these reasons, One Map Policy (OMP) is required to overcome the problems. The objective of this research was to develop datasets of one map of the coastal and marine resources needed for developing RZWP3K by using thematic layer maps produced by their respected Ministries/Agencies as the custodianships. The current custodianships of thematic maps in Indonesia is defined based on the Head of Geospatial Information Agency Decision Number 54 Year 2015. The method used the OMP approach was based on one reference, one standard, one database, and one geoportal. The research resulted the dataset of MGI integrated to the national basemap in a geodatabase format. From this research, it was concluded that the thematic maps of the coastal and marine resources which were produced in many institutions can be integrated to a national basemap and standard specification. The integrated thematic maps are then useful for developing the RZWP3K.


Rhizosphere soil of Phyllanthus species was screened for isolation of Arbuscular mycorrhizal (AMF) propagules. 12 species were isolated belonging to four genera Acaulospora, Entrophosphora, Glomus and Sclerocytis.


The study deals with the assessment of water quality parameters including pH, DO, BOD, temperature, TDS, EC, transparency, hardness, and alkalinity of the Turag River in Tongi, Gazipur, Bangladesh. The physicochemical parameters of water were investigated for 3 points in the Turag River through experimental methods. The river water was black in color and the odor was bad which indicate that the water is polluted and dangerous for aquatic ecosystem and human health. The temperature of water was within an average value of 28.39oC which indicates standard temperature (20 to 30oC) for aquatic medium. The average value of pH was 6.83, which indicates that the value was within the standard limits (6.5 to 8.0) for aquatic organisms. The values of DO water were within the range of 0.6 to 3.9 ppm with an average value of 2.25 ppm indicating low DO value from standard level (4.0 to 6.0 ppm for domestic and 5.0 ppm for fish culture). The values of BOD were within the average value of 1.15 ppm indicating lower condition compared to standard value of BOD (6.0 ppm for fish culture and 10.0 ppm for irrigation). The average value of TDS was 340.86 ppm which indicates low TDS condition. The EC values were ranged from 35 to150 μS/cm with an average value of 56.30 μS/cm which indicates lower condition than the standard value. The average value of transparency was 28.39 cm. The average value of hardness was 106.79 ppm which indicates near to the standard level. The average alkalinity was 237.66 ppm indicating very lower condition than the standard limit (2000 ppm for irrigation). From this investigation, it is recommended that the water quality of the Turag River is beyond the acceptable limit. So, effective measures should be taken to reduce the level of pollution and mitigate the existing aquatic environmental problems of the Turag River. DOI: http://dx.doi.org/10.3329/jesnr.v7i1.22140 J.

Chronic wound healing has become an area of fundamental research. Wound healing for a diabetic patient is one of the significant challenges in the biomedical field. Diabetes is a globally challenging disease that has affected around 400 million people. Many therapeutic factors are introduced to treat chronic wounds, with minimal success due to difficulty in delivery of the drug to the wound location. Microneedle patches are considered an efficient medical treatment procedure to address wound healing problems. The wound healing is accelerated, and the bacterial infection is inhibited by the devices based on microneedle with the loaded active drugs (including hemostatic drugs, bacterial drugs, and anti-inflammatory drugs). The wound healing process is generally divided into three steps: inflammation, proliferation, and tissue remodeling. This chapter will discuss the significant challenges and the advantages of microneedle applications in chronic wound healing.


Let Jk(*) = nrtr + • ■ • + asta, r > s, be the Jones polynomial of a knot if in S3. For an alternating knot, it is proved that r — s is bounded by the number of double points in any alternating projection of K. This upper bound is attained by many alternating knots, including 2-bridge knots, and therefore, for these knots, r — s gives the minimum number of double points among all alternating projections of K. If K is a special alternating knot, it is also proved that a3 = 1 and s is equal to the genus of K. Similar results hold for links. 1. Introduction. Let K be an oriented knot or link in S3 and let Jx(t) be the polynomial defined by V. Jones (5) which is now called the Jones polynomial of K. Jk (t) is an invariant of a knot or link type. It is not clear, however, to what extent Jk (t) is related to known algebraic or topological invariants in knot theory. Although it is shown (10) that Jk (t) determines the Arf invariant of a knot or a link, it is also known that Jk(i) does not determine the genus or the signature of K(8}. In this paper, we prove that for an alternating knot, Jk(t) provides some infor- mation that has never been obtained from other algebraic invariants. To be more precise, let K be an alternating knot in S3 and K an alternating projection of K. Let Jk(t) be the Jones polynomial of K.1 Write Jk(i) — artr + • • • + asts, where r > s and ar ^ 0 / as. Let h(K) be the number of double points in K. Then we can prove

According to the title, an extensive research was conducted with an objective to identify the characteristics of engineers with high 'engineering systems thinking' thinking skills and the processes by which it is acquired. The main question of the research was "what are the qualifications (knowledge, skills and aptitudes) required from systems engineers?" The General Systems Theory (GST) and the SCAW Model (Systematic Curriculum Alignment and Watch Model) for curriculum design of engineering disciplines constitute the theoretical frame of the research. Eighty‐three categories were found in 28 interviews, 14 lectures and 2 observation sites which may be assorted as follows: Ten categories referring to the definition of engineering systems thinking. Four categories deal with various types of systems thinking. Fifteen categories relate to knowledge required from systems engineers. Thirty‐one categories cover the skills demanded of systems engineers. Fifteen categories explore the personal aptitudes demanded of the systems engineers. Lastly, eight categories examine processes through which the system thinking capability is developed.

Data gathered using photogrammetry that represents the surface and structure of a heliostat mirror panel is investigated in detail. A curve-fitting approach that allows the retrieval of four distinct mirror error components, while prioritizing the best fit possible to paraboloidal terms in the curve fitting equation, is presented. The angular errors associated with each of the four surfaces are calculated, and the relative magnitude for each of them is given. It is found that in this case, the mirror had a significant structural twist, and an estimate of the improvement to the mirror surface quality in the case of no twist was made.


This paper is described on the outline of synsesis and its applicatrioin of layered hydrous titanium dioxide (H2Ti2O5⋅nH2O and H2Ti4O9⋅nH2O) fibers of two kinds. The layered hydrous titanium dioxide fibers were newly synthesized by extracting the interlayered potassium ions from K2Ti2O5 and K2Ti4O9 fibers in a hydrochloric solution. The ion-exchangeable properties of the H2Ti2O5⋅nH2O and H2Ti4O9⋅nH2O fibers are characterized to be excellent cation exchanger from the measurement of distribution coefficient for various metal ion series.The applications of ion exchanger are mainly described on separation and mineral immobilization of dangerous nuclides from viewpoint of treatment of high-level radioactive liquid waste and on adsorption of uranium from sea water.


Objective To analyze the effect of single nucleotide polymorphism(SNP)of SCN9 Agene for the patients with laparoscopic gynecologic operation.Methods A total of 200 patients with laparoscopic gynecologic operation were divided into ropivacaine group(group R)and control group(group C)based on the research method of control and double-blind.5min before cutting the skin,the incision site was locally infiltrated with 12 ml 0.75% ropivacaine(group R)and 12 ml normal saline(group C).The awakening situation after anesthesia and the amount of anesthetic during operation were recorded.By VAS,the pain degree of incision site was assessed and the postoperative adverse reactions were recorded.DNA was extracted from the peripheral venous blood of each patient,and PCR and DNA sequencing were applied to analyze the SNP of SCNA9 gene and the correlation with postoperative pain.Results The mutation(A/C)at 2794 in 15th exon of SCN9 Agene had no correlation with the postoperative pain.The mutation(C/T)at 3448 in 18th exon of SCN9 Agene had correlation with the postoperative pain(P0.05).Conclusion SCN9 Agene exon 18 3448(C/T)heterozygous mutation associates with the occurrence and development of postoperative pain.There is no significant correlation between SCN9 Agene 3448(C/T)mutation and ropivacaine for postoperative pain.

The density functional theory(DFT) based hybrid-method B3LYP has been used to study the interaction of the methanol molecule(CH_(3)OH) with the Ru(0001) surface.The perfect Ru(0001) surface has been represented by a cluster model,Ru(10,5),that was used to extract information about the preferred adsorption geometry and energy of CH_(3)OH species.Three typical adsorption sites,top,hcp and fcc sites,were investigated theoretically.The computed results show that the top site is the preferred adsorption site.The computed geometry for adsorbed CH_(3)OH agree with the structure proposed from previous experimental work about CH_(3)OH adsorbed on the transfer metal surfaces.


Training deep learning models on imbalanced data sets is difficult in practice because models tend to be biased towards predicting the majority class [21]. This poses a particular challenge in the medical field, not only because the minority class may often be a disease we are trying to di-agnose, but also because of the high risk nature of medical artificial intelligence (AI). In this paper we propose to rebalance imbalanced datasets by oversampling using Generative Adversarial Networks (GANs) [11]. We intentionally create an imbalanced dataset consisting of chest x-ray images labeled normal or pneumonia, with pneumonia images being the minority class. In particular, we consider Conditional Deep Convolutional Generative Adversarial Networks (cDCGANs), Deep Convolutional Generative Adversarial Networks (DCGANs) [26] conditioned on class labels [23]. For cDCGANs, we propose a new parameter α that indicates the probability of a randomly generated class label of 0. We then use these GANs to generate new synthetic pneumonia images. We train a ResNet18 model [15] on the new rebalanced datasets and compare their results to baseline, as well as some more common machine learning methods like undersampling, oversampling, class weights, and compare precision, recall/sensitivity, specificity, and the F1 score. Our results show that DCGAN and cDCGAN-based oversampling methods can outperform class weights and classic resampling methods in terms of F1 score, and outperform the baseline across the board, making GANs a valid method to rebalance datasets. Additionally, we found that our proposed α hyperparameter can potentially be used to tweak the sensitivity and specificity of the ResNet18 model. Abstract In order to improve model performance on imbalanced image datasets, we experiment with several techniques: undersampling, oversampling, image data augmentation [1], class weights, SMOTE [2], BorderlineSMOTE [3], and ADASYN [4], and compare results with baseline results obtained without any dataset preprocessing. The model used is ResNet18 [5]. These data preprocessing techniques are mostly able to achieve marginal improvements in the performance metrics on the test set. There is evidence from class activation maps [6] [7] that several data preprocessing techniques are able to allow the model to learn from more relevant parts of the image. In particular class weights emerges as a robust method in which to improve model performance and create models that learn reasonably, as indicated by class activation maps. There is also evidence one must be careful as to what kind of image data augmentation one uses, because doing very aggressive augmentation can degrade performance.


Hargreaves had made very famous theory of "emotional geography" theory,which includes political distance,distance of professional,ethical distance,physical distance and social and cultural distance of five levels.And that changes in education policies and education should give full consideration of the emotional factors of teachers,the construction of organizational culture in the school teachers to consider the emotional needs of teachers teaching in the classroom but also to practice using emotion to strengthen the emotional communication with students,to be at work with colleagues,leaders,parents set up a desired emotional connection

MCPD (monochloropropanediol) esters are some of the heat treatment contaminants found in refined oils and oily foods. In particular, they occur due to the processing of products containing oil and salt at high temperatures. Dietary MCPD esters are hydrolyzed as triglycerides in gastrointestinal tract, and free MCPD is released. Since free MCPD is carcinogenic, it is important to determine the amounts of MCPD esters in heat-treated foods. In this review, information on the formation, toxicity, identification and reduction of 3-MCPD esters and similar compounds are provided.


Children with cancer have high utilization of the emergency department (ED), but little is known about which outcomes are most important to them and their caregivers when they seek care in the ED.

Virtual measurement system is constructed using capacitive sensors from Feedback and ELVIS II hardware platform of National Instruments. The software controlling the system is developed in LabVIEW environment. Working algorithm for describing execution of the system is synthesized. Virtual capacitive transducer system is built with educational purposes.


It is well accepted that myoplasmic Ca ion concentration regulates muscle contractility. In skeletal muscle, in the contraction process, Ca ion is supplied exclusively from an intracellular Ca source in the sarcoplasmic reticulum, whereas, in smooth muscle, both intracellular and extracellular Ca sources have been proposed to contribute to contraction (Bolton 1979). At present, it is unclear where the intracellular Ca source (Ca store) is located in smooth muscle cells and how Ca ions are released from this store. Using guinea-pig mesentric artery chemically skinned with saponin, which makes the cell membrane, but not the sarcoplasmic reticulum, selectively permeable to solute molecules (Endo 1977), Itoh et al(l981) recently demonstrated the presence of Ca-induced release of Ca preloaded by ATP-dependent processes, and that its nature appears to resemble that observed in skeletal muscle. We now report that increased efflux of 45Ca preloaded in microsomes from guinea-pig taenia caecum is caused by a rise in extramicrosomal Ca ion concentration. Moreover, to assess this phenomenon pharmacologically, the effect of thymol on Ca-induced stimulation of 45Ca-efflux was also examined.


For arbitrary reduced words we give formulas for the crystal structures on string and Lusztig data of type A as well as the defining inequalities of the corresponding polytopes revealing certain dualities between them.


In this talk, I summarize a work done in collaboration with Otto Kong on the Zee neutrino mass model. We show that the MSSM with explicit R-parity violation actually contains the Zee model with the right-handed sleptons as the Zee singlet. We determine the conditions on the parameter space such that the neutrino mass matrix provides a viable texture that explains the atmospheric and solar data.


Calcium is a crucial signal molecule in the cardiovascular system. Calcium (Ca 2+ ) acts as a second messenger via changes in intracellular Ca 2+ levels through the actions of calcium channels and pumps. However, it is now well known that calcium may also be an extracellular first messenger through a G-protein-coupled receptor that senses ex- tracellular Ca 2+ concentration, the calcium-sensing receptor (CaR). The CaR is one of the key players in extracellular cal- cium homeostasis, but besides being expressed in the major organs involved in calcium homeostasis, the parathyroid gland, kidney and intestine, the CaR has also been found to be functionally expressed in other tissues. Although several studies demonstrated the CaR in heart and blood vessels, exact roles of the receptor in the cardiovascular system still re- main to be elucidated. This review will summarize the current knowledge on the expression and possible functions of the CaR in the cardiac tissue.


Cyber bullying is becoming major concern especially when social media is booming and the increase amount of usage of social media. To explain this phenomenon, theoretical frame work "Spiral of silence" theory is used in this research article. The survey was distributed to university students and to perform the survey 300 sample size of university students were chosen. The results were analyzed using Percentage method. Results indicated that university students who were victimized by cyber bullying experiences Harassment, threats, body shamming and hateful comments. Most of the cyber bullying victims are girls. The researcher was able to find how bullying affect mental health of youngsters. The researcher was also able to determine that cyber bullies is not always suicide is not ended up at suicide. The researcher also recommended that government should give awareness about bullying laws and it should be discuss in institutions as well.


The focused ion beam miller (FIB) has been widely used in the semiconductor industry for many years, but only recently has its potential as a tool for materials science been recognised. The FIB uses a highly energetic beam of gallium ions to sputter material such that it can precisely section, as well as image, areas of interest. The FIB can be used to create crosssections, which can be examined in the FIB or in a scanning electron microscope (SEM). Cross sections can be made from delicate samples or samples in which a specific area needs to be viewed, for example to check the thickness of coatings or for failure analysis. The FIB may also be used to prepare transmission electron microscope (TEM) specimens [1]. Extremely site-specific thin areas may be prepared with high positional accuracy from heterogeneous samples such as composites or layered structures.


First-principle calculations have been performed to study the electronic structure and energetics of the dissolution of aluminum in ! -iron and the interaction between Al atoms and vacancies ! V" . We find that the formation of small VnAlm complexes ! n,m=0‐4" is energetically favorable. Their stability is mainly driven by strong Al-V attractions whereas Al-Al interactions are repulsive. Using ab initio predictions, a rate theory based model that accounts for the evolution of aluminum and vacancies created upon rapid quenching has been developed to explore the influence of Al in the presence of the VnAlm complexes in ! -iron. Finally, using the Le Claire's diffusion model, the diffusion properties of solute Al are investigated.


The systematics, throughout the periodic table, of the (/sup 6/Li,d) and (d,/sup 6/Li) reactions are reviewed. The ..cap alpha..-spectroscopic factors extracted exhibit correlations with shell effects, nuclear pairing and nuclear deformation. The data are compared with calculations using SU3, pseudo-SU3, the jj-shell model, the pairing-vibration and boson-expansion models. Many, but not all of the experimental features are reproduced by existing models. 37 references.


Introduction: Breastfeeding has been identifi ed as the optimal source of nutrition for infants. However, many mothers do not breastfeed their infants excusively. The possible modifi able factors to improve breastfeeding rates are breastfeeding self effi cacy and effective breastfeeding behavior. The aim of this study was to analyze the breastfeeding support package to improve breastfeeding self effi cacy and impact on effective breastfeeding behavior.Methods: This study was a quasy experiment pre-post test non equivalent control group design. Samples were 20 respondents recruited using consecutive sampling in Navy Hospital Dr. Ramelan who met the inclusion criteria. Instruments that used in this study were breastfeeding self effi cacy short form and LATCH assessment tool.Results: The score of breastfeeding self effi cacy on experiment group was improve higher than control group. But, the hypothesis test showed that there were no difference score between experiment and control group after intervention (p = 0.104). The correlation between breastfeeding self effi cacy and effective breastfeeding behavior was not signifi cant (p = 0.976). Conclusion: The antecedent of breastfeeding self effi cacy were not only the information resources but also job and education level. Breastfeeding self effi cacy was not an antecedent of effective breastfeeding behavior.


Abstract Organoboration of dimethyl(chloro)-1-propynylstannane with triethylborane gives (E̲)-2-dimethyl(chloro)stannyl-3-diethylboryl-pent-2-ene (2a) in high yield. Reactions of 2a with N- and C-lithiated azoles (pyrazole, 1-m ethylimidazole, 1-methyl-1,2,4-triazole) lead to the new fused heterocyclic systems 8, 10, 12. In the case of 10 and 12 it was possible to detect (by 11B, 119Sn NM R ) the isomers 9 and 11 which have a zwitterionic structure with an Sn-N linkage. After heating, the compounds 9 and 11 rearrange quantitatively into 10 and 12, respectively. These results show the com petition between boron and tin in 2a as electrophilic centres.


Objective To evaluate the imaging features of digital subtraction angiography (DSA) for the primary hepatocellular carcinoma with portal vein tumor thrombus(PVTT),and explore the methods and value of indirect portography. Methods Totally of 72 patients with PVTT from March 1994 to June 2001 in our hospital received superior mesenteric arteriography, celiac arteriography and hepatic arteriography. The DSA appearances in all of the patients were observed dynamically. After reading the angiograms together and making a consensus, 2 experienced radiologists determined the presence of PVTT. Results In the 72 cases, tumor thrombi of the main portal vein were seen in 22 cases, right portal branch in 12 cases, left portal branch in 10 cases,portal trunk with right portal branch in 14 cases,portal trunk with left portal branch in 6 cases,and tumor thrombi of portal trunk with left and right portal branch in 8 cases. There were many kinds of DSA appearances of the PVTT , such as filling defect,the thread and streaks sign and cavernous transformation of portal vein(CTPV). Conclusion The indirect portography has high sensitivity and specificity for the diagnosis of the PVTT. The filling defect,the thread and streaks sign and CTPV of portal vein are considered to be pathognomonic for PVTT.


Scattering lengths and their reciprocals for elastic collisions between zero-energy electrons and helium atoms have been calculated using Kohn's variational method. The trial function used makes explicit allowance for correlation between the incident electron and the atomic electrons, and is properly antisymmetrized to allow for electron exchange. In addition the trial wave function depends upon three exponential parameters as well as a number of linear parameters. The `best' values obtained are 1.10 a0 for the scattering length, and (1.11 a0)-1 for the reciprocal of the scattering length. Our value for the scattering length is slightly lower than the 1965 experimentally determined value 1.15 a0 of Golden and Bandel, but is very close to the value 1.097 a0 calculated by LaBahn and Callaway in 1966.


In 1979, Northern Natural modified its 300 million CF/day triethylene-glycol gas-dehydration plant in Kansas to recover enough waste heat from the reciprocating-compressor engine exhaust to regenerate the circulating glycol. The annual fuel saving amounts to about 55 million SCF. Such retrofits, however, call for especially close attention to equipment specifications, particularly for valves. Corporate economics must dictate the final decision on whether to initiate such conservation projects.


The effects of eight different dispersants on the stability of multiwalled carbon nanotubes (MWCNTs) in vinyl ester (VE) resin systems have been systematically analyzed. Suspensions incorporating different amounts of dispersants relative to the concentration of MWCNTs in the VE have been prepared. The resistance to sedimentation of MWCNTs in the resin was investigated by using a centrifugation technique. One dispersing agent (B60H) was found to impart long-term stability to suspensions of MWCNTs in VE. VE-based composites reinforced with MWCNTs were prepared using different amounts of the dispersing agent. Tensile tests were performed to analyze the effect of different concentrations of MWCNTs and the use of the dispersing agent in the composites. Fracture surfaces of VE nanocomposites have been analyzed using scanning electron microscopy (SEM) to elucidate the reinforcing effect of the CNTs. POLYM.

This paper considers the application of the triple Langmuir probe method to investigate the local plasma parameters of the radio frequency (RF) discharge that is placed in the applied magnetostatic field. The main criteria applicability for such a method for experimental diagnostics of RF plasma parameters is presented. As an example, this paper presents experimental results that were obtained using the proposed method on local plasma parameters in one of the cross sections of the discharge chamber of the RF ion source with an applied magnetostatic field. The influence of the magnetostatic field on the radial distributions of charged particle density and electron temperature is shown.


This work analyses the presence and management As personalized digital networks have increased in cultural and political relevance, there is a more urgent need to understand their role in democratic memory-formation. Moreover, scholars have suggested that, in a globalized digitalized age, collective memory could extend to transnational publics. This study aims to advance the understanding of memory on global social networks by investigating the way the death of George Floyd in the summer of 2020 was treated and understood by Twitter-users outside the United States. Using a combination of big data and contemporaneous qualitative interviews with users in Norway, Sweden, and Denmark, the paper brings the concept of cosmopolitan memory into the social media era. The study finds that users fused the event and its aftermath with observations of injustice in their own countries. However, this process operated differently among users of different ideological outlooks. Another key finding is that users on the radical right resented the uptake of the event as a cosmopolitan memory, and employed techniques termed as "combative counter-memory".


Pacific silver fir (Abies amabilis Douglas ex J. Forbes) was first introduced to Britain in 1830 but has not been widely planted and occupies a minute part of the forest estate. The results of six experiments established in the uplands of Britain examining material from 30 collection sites in 14 seed zones clearly demonstrate that its potential has not been recognised. The trials were assessed after 28 years and show that Pacific silver fir has the potential to be as productive as other common species options. There was little variation in performance between the 14 seed zones, and future seed collections could be carried out within a wide geographical range, including mainland British Columbia and Vancouver Island and the Olympic Mountains and western Cascades of Washington. The silvicultural characteristics of the species mean that it could be used more widely to diversify forests in Britain both as a plantation species and in the wider use of continuous cover management. More work is justified to deter...


A robust 2,2'-bipyridine (bpy)-derived biological hydrogen-bonded framework (HOF-25) has been realized depending on guanine-quadruplex with the assistance of π-π interaction, which reacts with Re(CO) 5 Cl to give a post-functionalized HOF-25-Re. X-ray absorption fine structure spectroscopic study on HOF-25-Re confirms the covalent attachment of Re(bpy)(CO) 3 Cl segments to this HOF. Robust and recycled HOF-25-Re bearing photocatalytic Re(bpy)(CO) 3 Cl centers displays good heterogeneous catalytic activity towards carbon dioxide photoreduction in the presence of [Ru(bpy) 3 ]Cl 2 and triisopropanolamine in CH 3 CN under visible-light irradiation, with both high CO production rate of 1448 μmol g -1 h -1 and high selectivity of 93%. Under the same conditions, the experimental turnover number of HOF-25-Re (50) is about 8 times as that of the homogeneous control Re(bpy)(CO) 3 Cl. The sustainably regenerated HOF-25-Re via crystallization and post-modification processes shows recovered photocatalytic performance.


Background Trimethylamine N-oxide (TMAO) and its precursors have an association with type 2 diabetes mellitus (T2DM); however, the evidence is unclear. The current study examined the association of serial measures of serum TMAO and related metabolite concentrations with the risk of T2DM. Methods Our study was designed as a community case-control study with 300 participants (150 T2DM and 150 non-T2DM). We examined the association of serum concentrations of TMAO and its related metabolites [trimethylamine, choline, betaine, and L-carnitine] using UPLC-MS/MS. The association between these metabolites and the risk of T2DM was analyzed using a restricted cubic spline and binary logistic regression. Results A higher serum choline concentration was significantly associated with an increased risk of T2DM. Serum choline > 22.62 μmol/L was independently associated with an increased risk of T2DM, and the odds ratio was 3.615 [95% CI: (1.453,8.993), P = 0.006]. Similarly, serum betaine and L-carnitine concentrations had a markedly decreased risk of T2DM even after adjusting for the traditional risk factors for T2DM and betaine (0.978 [95% CI:0.964–0.992], P = 0.002) and L-carnitine (0.949 [95% CI: 0.9222–0.978], P = 0.001), respectively. Conclusion Choline, betaine, and L-carnitine are associated with the risk of T2DM and may be appropriate risk markers to protect high-risk individuals from T2DM.
