The article is devoted to the description of the results of a study of students' satisfaction with the organisation of distance learning at the university, the difficulties encountered in learning under new conditions of self-isolation, resources and ways to overcome them. The study involved 1288 students of Kostroma State University of all courses, forms of study and educational levels. For statistical data processing, the SPSS 17.0 package (Spearman's correlation analysis, content analysis of students' free statements) was used. It is shown that the transition to distance learning in conditions of self-isolation is very successful, most students have adapted to the new situation. The degree of students' satisfaction with work in the remote format correlates with the assessment of their own success and with the features of the organisation of the learning process. Lack of communication with teachers and difficulties in mastering educational material form a request among students to expand the range of communication tools and teaching tools used. It was found that students experience a number of organisational and personal difficulties associated with the transition to a distance learning format. However, most students successfully overcome them using constructive coping strategies aimed at solving the problem and seeking support. The ways of increasing the degree of students' satisfaction with work in the distance learning system, aimed at increasing the level of their psychological well-being, are proposed – focusing on a dialogical approach, organising methodological support for training courses, updating the organisational functions of curator teachers, implementing teamwork of teachers to ensure interdisciplinarity and integrability of acquired knowledge and competences.


Analytical bibliography, long one of the scholarly roots of librarianship, is exemplified in its modern form by A. W. Pollard's landmark study, Shakespeare Folios and Quartos, published in 1909 [1]. Before Pollard, others had studied paper and printed type in the course of investigations of printing itself, but he pioneered by using the facts derived from a study of printed books as a basis for inferences concerning the intellectual content of those volumes. Pollard's place as a pioneer is firmly established by the comprehensive and purposeful character of his work, which not only reached new conclusions about Shakespeare's text but also became a methodological model. In single instances, however, a few investigators had used the same methods before Pollard. It is peculiarly appropriate that one of those predecessors was a librarian. This paper describes the use, in a study published in 1867 [2], of signature marks and of a peculiarity of type in a running title as the basis for historical inference. Although there is no intention here to settle the important historical controversies involved, an adequate understanding of the bibliographical issue requires some knowledge of the background. The subject of the 1867 study is Edward Johnson's Wonder-working Providence of Sion's Saviour in New England, originally published under a different title in London in 16531 [3]. Johnson's description of pioneer days in Massachusetts makes the work an essential document for all students of early New England history. By the middle of the nineteenth century copies were so scarce that the Librarian of the Boston Athenaeum, W. F. Poole, decided to prepare a near-facsimile edition accompanied by a new introduction. In the course of his investigation, he used the bibliographical evidence in ways that earn his work a modest place in the history of analytical bibliography. William Frederick Poole (1821-94) is best known today as the compiler of the first general index to periodicals. He was also a distinguished librarian, heading successively the Brothers in Unity Library of Yale College, the Mercantile Library Association of Boston, the Boston Athenaeum, the Cincinnati Public Library, the Chicago Public Library, and the Newberry Library. A leader of the group that founded the American Library Association at Philadelphia in 1876, Poole served as the Association's president from 1885 to 1887. He was also a scholar of considerable ability whose standing among historians earned him election to the presidency of the American Historical Association in 1887. His experience prepared him well for bibliographical study. In the course of publishing his index to periodicals, he learned the essentials of printing practices. Books were his stock-in-trade as a librarian. Particularly in his work at the scholarly Boston Athenaeum, he became

Companion animals are now living longer and so are more commonly manifesting age- and pain-related disease. Nonsteroidal anti- inflammatory drugs are the most used drug in osteoarthritis and inflammatory pain of various aetiologies. Despite their safety profiles have been amended from the COX-non selective to the COX-2 selective inhibitor class, some adverse effects are still of concern especially in long term treatments. One prostaglandin (PG) downstream from the cyclooxygenase enzyme, PGE2, has been recognized as a pivotal mediator of pain and inflammation. The actions of PGE2 are produced by its interaction with four G-protein coupled receptors (EP1, EP2, EP3 and EP4). The EP4 receptor mediates PGE2-elicited sensitization of sensory neurons and studies have demonstrated that EP4 is a major receptor in mediating pain associated with both rheumatoid and osteoarthritis and in inflammation. CJ-023,423 (grapiprant) is a competitive antagonist of human and rat prostanoid EP4 receptors, under development for the control of pain and inflammation associated with osteoarthritisfor use in humans and dogs. A recent study has shown the good safety profile of this active ingredient in dogs. Despite this molecule is still far to be marketed because it pharmacokinetic/pharmacodynamics profile is need to be fully elucidated yet, it might be an interesting active ingredient for the veterinary medicine. activities. Two isoforms of COX, COX-1 and COX-2, have been identified. COX-1 is constitutively expressed throughout the body and it is thought to play an essential role in normal gastrointestinal and renal function, whereas COX-2 is induced in the presence of inflammation. NSAIDs inhibit both isoforms and inhibition of COX-1 is thought to cause the adverse gastrointestinal effects such as gastric erosion, ulceration and haemorrhage, whereas inhibition of COX-2 is associated with the therapeutic effects of NSAIDs. Thus, inhibition of PG synthesis by NSAIDs has demonstrated clear efficacy in the reduction of pain and inflammation and also has been shown to have putative effects beyond pain, including gastrointestinal and renal effects. These effects have been shown to be more severe in several animal species rather than in human beings (Khan and McLean, 2012). Selective COX-2 inhibitors were designed to prevent those adverse effects mediated by


Objectives: To assess gully erosion in parts of Enugu north, Southeastern Nigeria using some geotechnical parameters. Method: The soil samples were collected from different gully point and some geotechnical parameters was analyzed in Soil Science Department, University of Nigeria in accordance with the specified standard procedures. Finding : The assessment of gully erosion in parts of Enugu north, southeastern Nigeria, has been carried out. Soil samples were collected from the four major gully points, at the depth range of 0.5 to 1.0 m using soil auger, core samplers and hammer. The soil classification shows that the textural characteristics were predominantly sandy, loamy and clayey. Liquid limit (LL) ranged from 16.67 to 46.89%. Plastic limit (PL) was 33.45% in Igbo-Eze South and 22.38% in Nsukka. None plastic limit were observed in Igbo-Eze North and Udenu. Percentage plasticity index (PI) of 13.44% was depicted in Igbo-Eze South and 9.90% in Nsukka. Zero plasticity indexes were noted in Igbo-Eze North and Udenu. Bulk density test ranged from 1.39 to 1.56 g/cm 3 . Porosity ranged from 41.13 to 47.55%. The hydraulic conductivity and moisture content are ranged from 8.89 to 22.73 m/day and 7.07 to 31.73% respectively. These results indicate presence of coarse sand, fine sand, low amount of clay and silt in small proportion, loosed soil with low binding materials, instability of soil structure, low moisture content and other bio-activities that contribute to the rate of increase of gully erosion in the study area. Novelty : The estimated geotechnical parameters, including Atterberg limit (plastic limit, liquid limit and plasticity index), hydraulic conductivity of the soil, soil aggregate stability, particle size distribution, bulk density, total porosity proffers solutions to the gully problem in the area. The low moisture content value shows that the soils are loose and hence cannot hold much water longer enough. Therefore, the low moisture contents of the subsurface soils lead to low capacity for water retention during rainfall. According to (42) , such low moisture contents causes breakdown on the grain-to-grain forces that existed in the soil. The soil bulk density test conducted on the four gully samples varies from 1.39 to 1.56g/cm 3 . The results indicate that the bulk density of soil is relatively low, poorly consolidated, and this indicates that the soils are not compacted but very loose and therefore prone to erosion. The value of these bulk density values are within the low value range as stated by (24) . However, the value percentage of total porosity ranged from 41.13 to 47.55%. The results show that the gully sample within Igbo-Eze south and Nsukka have relatively medium porosity, which indicates that the soil particle texture contains more of sandy soil which have larger macro-pores. Within Igbo-Eze north and Udenu, the porosity values were seen to have a little decrease in porosity value which indicates that the soil contains more of fine textures such as clay or silt soil which has micro porosity. Therefore, it is pertinent to state that finely textured soils like clay or silt with micro-pores and coarse soil such as sandy soil with macro-pores can have large pores known as bio-pores. These bio-pores are the spaces between soil particles created by termites, earthworms or decaying plant roots. These large pores increase the rate at which water permeate the soil, and therefore, increases the rate at which the erosion occur in the area. In the same way, the hydraulic conductivity which determines how the fluid passes through the pores and fractured rocks has range of values from 8.89 to 22.73m/day. These results indicate that area with low value of conductivity were majorly dominated with silt, clay soil or the compatibility of soil is high, whereas area with relatively increase in hydraulic conductivity value shows that the textural class is more of loose materials such as sandy soil or the area with more of biological activities like decays of roots crop and activities of other insect. states that the hydraulic conductivity


Objective
To compare the surgical outcome of intracerebral hematoma drilling and drainage for hypertensive intracerebral hemorrhage (HICH) using robotized stereotactic assistant(ROSA)-assisted and stereotactic framework.

Methods
A retrospective study was conducted on 368 patients with HICH who underwent hematoma drilling at Department of Neurosurgery, General Hospital of Shenyang Military Command from March 2015 to April 2017. According to the surgical method, all cases were divided into the stereotactic frame group (group A) and ROSA group (group B). Comparison was conducted on the treatment outcome of those 2 surgical methods for HICH.

Results
There was no statistically significant difference in gender, age, preoperative GCS (Glasgow coma scale), time interval from bleeding to operation and bleeding volume between 2 groups (all P>0.05). The operating time (27.3±8.4 min) and incidence of rebleeding (1.7%, 3/172) were lower in group B than those in group A [operation time: (44.2±7.7) min, incidence of rebleeding: 8.7% (17/196)] (both P<0.01). In group A, 12 (6.1%) patients developed postoperative intracranial infection and none had intracranial infection in group B and there was statistically significant difference between the 2 groups (P=0.001). The extubation time in groups A and B was (2.5±0.7) days and (1.2±0.5) days post opeartion, respectively, which were significantly different (P<0.001). The 30-day mortality rate in group B (2.3%, 4/172) was lower than that in group A (9.2%, 18/196) (P=0.006).

Conclusion
Compared with stereotactic frame-assisted surgery, ROSA-assisted operation seems to be associated with shorter operation duration, earlier extubation time, and lower incidence of postoperative rebleeding, intracranial infection and 30-day mortality rate for HICH patients, which is thus worthy of clinical promotion.

A simple and rapid method was described for the determination of methylparaben,ethylparaben,propylparaben,butylparaben,BHA,BHT and TBHQ in food with complex matrices,by gas chromatography with mass chromatography(GC/MS).The detection limits were 0.05 to 0.5 mg/kg for all compounds based on a 5.0 g sample.Overall recoveries(%) and relative standard deviations(RSD) ranged from 94.4% to 105.1% and from 3.9% to 9.9%,respectively for all analytes.The method might be useful for the quality surveillance of food with complex matrix.


The soil water content in different root zones under localized supplies of water and nitrogen fertilizer was studied with maize grown in split-root containers.Maize was irrigated in both halves of the pot(C) or water was alternatively supplied to two halves of the pot(alternative partial root-zone irrigation treatment,A).Urea was applied to both halves of the pot(J) or was fertilized to one half of the pot while the other half was kept without N fertilizer(partial root-zone fertilization treatment,P),all with four levels of fertilization,i.e.zero,low,medium and high.For J-fertilization,the soil water content(SWC) was the same for two root zones under C-irrigation while SWC of two root zones changed alternatively and SWC of the irrigated zone was always larger than that of the non-irrigated zone under A-irrigation,and this was more obvious after irrigation.For both C-irrigation and A-irrigation,N fertilization increased the residual SWC before irrigation.Moreover,both the increment and duration rose with N rates.For C-irrigation,the residual SWC in two root zones was equal under J-fertilization while the residual SWC of the fertilized zone was significantly larger than that of the non-fertilized zone under P-fertilization.Under A-irrigation and P-fertilization,both partial root-zone irrigation and partial root-zone fertilization caused the asymmetry of SWC in two root zones.Moreover,the effect of partial root-zone irrigation was larger than that of partial root-zone fertilization for low N rate and the early time after fertilization,and the effect of partial root-zone fertilization was larger than that of partial root-zone irrigation for medium and high N rates and the late time after fertilization.Higher N fertilization could increase the capacity of soil water conservation for both two irrigation and two fertilization methods.

Keystone rings with overall side angles of 6° and 15° are specified by the International Organization for Standardization (ISO), Japanese Industrial Standards (JIS) and SAE. This research investigated the effect of overall side angle on breakage of the keystone ring. We used simple models to calculate the side clearance between the ring and the ring groove, the mean colliding force between the ring and its groove, and the stress of ring edge under disc-spring deformation. Our results suggested that a keystone ring of a 6° angle (and thus a narrower side clearance) increased breakage resistance, as compared to a ring with a 15° angle (and a wider side clearance).


To mitigate the two limitations existing in the conventional procedures of Nicolson-Ross- Weir (NRW) method, namely thickness resonance and multi-value problems, an alternating iteration algorithm is proposed for accurately retrieving the complex permittivity of non-magnetic materials based on rectangular waveguide measurements. The mechanism for the generating of the two limitations are reviewed and explained with the detailed procedures. Then, two different types of formulas are combined together for alternately iterative calculation, effectively eliminating two limitations simultaneously. The proposed algorithm has been described, and verified with numerous simulations as well as experiments, exhibiting robustness and high accuracy.


Urinary nitrogen excretion by the rat increases after whole body x-irradiation. This response to irradiation is suppressed by adrenalectomy and can be restored by treatment of the x-irradiated adrenalectomized rats with adrenal cortical extract. The weights of the thymus and the spleen are decreased and the weight of the liver is increased in the rat following whole body x-irradiation; adrenalectomy produces only quantitative changes in these responses without affecting the direction of the changes. Blood amino acid levels are not affected appreciably by x-irradiation. From these facts it appears that nitrogenous materials other than amino acids or simple polypeptides are transferred from certain body tissues to the liver after irradiation. In the normal irradiated animal these nitrogenous materials are converted in the liver to glycogen, and the excess nitrogen appears in the urine. In the adrenalectomized irradiated animal the liver is unable to carry out this conversion. Treatment of the adrenalectomiz...


The main purpose of this paper is to introduce an approach to the simulation of coal-mining concentrative emission gas spreading in ventilation networks based on the Lattice Boltzmann Method (LBM).As is known,concentrative emission of high-pressure gas in underground mining often results in mining pit explosion.Therefore, it is of great emergency to explore the regularities of the gas spreading occurrences in the ventilation networks so as to make a better control and prevent from any gas-explosion disasters in the underground con- ditions.It is just from this imperative need that we have developed a simulation model of concentrative emission gas spreading in the above-said situations,in which a double distributed velocity-concen- tration LBM is adopted.In order to simulate the complicated situa- tions,tunnels are separated into some relative regular blocks through the block coupling algorithms.In the model,each block is calculated in parallel,with the data exchanged only on boundaries.As a result, the redundant grids are removed and the grid computation has been simplified with the system resource efficiency ameliorated.While constructing the gas spreading velocity and the gas concentration for- mulation,we have coupled the two sides organically by using Boussi- nesq equation.The simulation results show that the so-called LBM model is in a position to obtain essential data and information on the velocity,pressure and visual information about the gas in the tunnels. The simulation results also help to disclose the regularities on the dis- tribution of gas bulk fraction in the tunnels,and those on the speed, pressure and bulk fraction of the gas in different points and places in the tunnels,which are of great benefit for mine safety control and management.Advice and suggestions have also been made that min- ers and technicians should not stay in the comers and concourses of two or more tunnels where air and gas exchanges are done in a turbu- lent manner at concentrations higher and thicker so as to avoid the concentrative emission gas spreading.


BACKGROUND
The effects of catheter ablation for atrial fibrillation (AF) on hemodynamic parameters in patients with preserved left ventricular (LV) systolic function are unclear. Methods and Results: We enrolled 178 patients with AF (paroxysmal, 108; persistent, 70) with preserved LV systolic function who underwent AF ablation. The stroke volume index (SVI) was repeatedly measured using impedance cardiography. Reduced SVI (SVI, <33 mL/m2) was observed in 55% of patients before ablation. In patients with paroxysmal AF, the SVI did not change immediately after ablation (from 35±6 mL/m2to 35±5 mL/m2; P=0.652); however, it increased 1 month after ablation and further increased 6 months after ablation (1 month, 37±6 mL/m2, P<0.001; 6 months, 38±6 mL/m2, P<0.001). In patients with persistent AF, the SVI increased immediately after ablation (from 30±5 mL/m2to 36±6 mL/m2; P<0.001) and further increased until 6 months after ablation (1 month, 37±6 mL, P<0.001; 6 months, 38±5 mL/m2, P<0.001). The baseline SVI was the strongest predictor of the cardiac function improvement with an area under the curve of 0.828.

CONCLUSIONS
The restoration and maintenance of sinus rhythm using catheter ablation increased the SVI in patients with preserved LV systolic function.


historical examples from the Greco-Roman world. The final chapter in this section highlights the politics of food and the ways in which it is used to both create and register social differences and inequalities. Using ethnographic and historical examples, the author considers first the role of food in "engendering" societies and the ways men and women engage with it differentially. This is followed by a review of archaeological literature on the political significance of feasting events that relies heavily on the work of Michael Dietler and Brian Hayden and their classic volume, Feasts (2001). The chapter concludes with an extended discussion of the role of eating and drinking in the Mississippian world of eastern North America and the ways in which food practices changed in tandem with the increasing centralization of power. The emphasis throughout this section is on the importance of utilizing a comparative approach and multiple datasets in food archaeology. The final part of the book turns to questions of identity, providing various ethnographic, historic, and archaeological examples of how food is used to create and negotiate group membership and social status. Chapter 7 considers identity at different scales— including national, community, and family. The next chapter shifts attention to the individual and the body, providing a discussion of how these are differentially conceived cross-culturally—for example, the body as partible, permeable, or closed, together with ideas surrounding the ways in which personhood is constructed. Chapter 8 closes, as do the others, with the detailed presentation of an archaeological example—in this case, focusing on research at the site of Çatalhöyük—intended to illustrate how archaeological data can inform on these topics. In sum, this volume offers a useful review of the different angles that ethnographic studies centering the social significance of food and eating have taken, as well as what "food archaeology" has to offer. The mode of presentation throughout, which involves the intertwining of social theory with ethnographic data, historical material, and "how to" archaeological examples, is distinctive and instructional. The decided emphasis on late twentieth-century social theory and studies, however, is curious given that scholarship has continued to develop with respect to embodiment, materiality, personhood, and identity in recent decades. Nonetheless, The Social Archaeology of Food makes a well-grounded case for the significance and centrality of food in human societies past and present, and the reasons a broader orientation to food in archaeological studies should have an important place at the table.

The authors present direct measurements of the left-right asymmetry of b- and c-quarks from the decay of Z{sup 0} bosons produced in the annihilation of longitudinally polarized electrons and unpolarized positrons. Two complementary techniques are presented: (1) Z{sup 0} {yields} b{bar b} decays are tagged using track impact parameters with b{bar b} discrimination provided by momentum-weighted track charge; (2) semileptonic b-decays are tagged using high p and p{sub T} muons and electrons. The preliminary results from their 1993 data sample are: A{sub b} = 0.93 {+-} 0.13 {+-} 0.13 for the jet charge and A{sub b} = 0.93 {+-} 0.14 {+-} 0.09, and A{sub c} = 0.40 {+-} 0.23 {+-} 0.20 for the leptons, where the first error is statistical and the second systematic.


In this work, we use cosmography to alleviate the degeneracy among cosmological models, proposing a way to parametrize matter and dark energy in terms of cosmokinematics quantities. The recipe of using cosmography allows to expand observable quantities in Taylor series and to directly compare those expansions with data. The strategy involves the expansions of q and j, up to the second-order around a(t) = 1. This includes additional cosmographic parameters which are fixed by current values of q0 and j0. We therefore propose a fully self-consistent parametrization of the total energy density driving the late-time universe speed up. This stratagem does not remove all the degeneracy but enables one to pass from the model-dependent couple of coefficients, ω0 and Ωm,0, to model-independent quantities determined from cosmography. Afterwards, we describe a feasible cosmographic dark energy model, in which matter is fixed whereas dark energy evolves by means of the cosmographic series. Our technique provides robus...

ABSTRACT Anew model for the temperature rise of an infinite medium with a thermal probe is developed which accounts for the finite diameter and specific heat of the probe. The new model is more accurate than the old model as demonstrated during the determination of thermal diffusivity of burley tobacco in bales. Multiple thermocouples in the medium and multiple probings are suggested for the determination of thermal diffusivity. Reduction of moisture diffusion to a negligible level is discussed.


A class of $\ell_1$-regularized optimization problems with orthogonality constraints has been used to model various applications arising from physics and information sciences, e.g., compressed modes for variational problems. Such optimization problems are difficult to solve due to the nonsmooth objective function and nonconvex constraints. Existing methods either are not applicable to such problems or lack convergence analysis, e.g., the splitting of orthogonality constraints (SOC) method. In this paper, we propose a proximal alternating minimized augmented Lagrangian method that hybridizes the augmented Lagrangian method and the proximal alternating minimization scheme. It is shown that the proposed method has the so-called subsequence convergence property; i.e., there exists at least one convergent subsequence, and any convergent subsequence converges to a Karush--Kuhn--Tucker point of an equivalent minimization problem. Experiments on the problem of compressed modes illustrate that the proposed method ...


In the tumor microenvironment, adipocytes function as an alternate fuel source for cancer cells. However, whether adipocytes influence macromolecular biosynthesis in cancer cells is unknown. Here, we systematically characterized the bi-directional interaction between primary human adipocytes and ovarian cancer (OvCa) cells using multi-platform metabolomics, imaging mass spectrometry, [13C]-glucose isotope tracing, and gene expression analysis. We report that omental tumor explants and OvCa cells co-cultured with adipocytes divert part of the glucose from glycolysis and TCA cycle towards glycerol-3-phosphate (G3P) synthesis. Normoxic HIF1α protein, stabilized by adipokines, regulate this altered flow of glucose-derived carbons in cancer cells, resulting in increased synthesis of glycerophospholipids (GPL) and triacylglycerols. Blocking adipocyte-induced HIF1α expression increases lipid peroxidation levels in cancer cells and sensitizes them to ferroptosis-mediated cell death. Subsequently, the knockdown of HIF1α or G3P acyltransferase 3 (a regulatory enzyme of GPL synthesis) reduced metastasis in xenograft models of OvCa. In summary, we show that in an adipose-rich tumor microenvironment, cancer cells generate G3P as a precursor for critical membrane and signaling components, thereby promoting metastasis. Targeting biosynthetic processes specific to adipose-rich tumor microenvironments might be an effective strategy against metastasis.


SUMMARY In our society, techniques of communication increase in number. What are they ? What new forms of social link go with them ? How are we supposed to think the relationship between techniques and society ? Such are the questions we have to ask. They imply a social unconscious charaderistic of modem societies and, in feed-back, the effects of the technical logic.


SUMMARY We solve by a finite difference method a system of simultaneous non-linear partial differential equations which modelizes the transfer of heat and mass when a fluid evaporates from the hot wall and condenses on the cold wall of an upright rectangular cavity. The need to verify a certain condition associating the physical parameters of the fluid for the existence of steady state solutions is proved.


e16099 Background: MET has been known as an important therapeutic target in various solid cancer types. With the establishment of next-generation sequencing (NGS) in the oncology clinics, understanding the incidence of MET aberration in patients with metastatic cancer is critical for oncology drug development and efficacy. We investigated MET gene aberration in 2,239 oncology patients who underwent NGS in clinical practice with real-world data. Methods: From Nov. 2019 to Jan. 2021, 2,239 metastatic solid tumor patients who visited oncology clinic were enrolled in the NGS analysis. The NGS panel (TruSight Oncology 500 Assay, Illumina) was over 500 comprehensive sequencing using archival tissue specimen. In addition, PD-L1 22C3 assay results were available in 1,137 patients (50.8%) and 1,761(78.7%) patients had clinical record about 1st chemotherapy for overall survival analysis. Results: 2,239 patients with metastatic solid tumor (37 cancer types) received NGS as part of the clinical practice with an aim to be guided to targeted agents or immunotherapy. The most common cancer types were CRC (N = 702, 31.4%), followed by GC (N = 481, 21.5%), and sarcoma (N = 180, 8.0%). Of 2,239 patients, any MET aberrations (CNVs, fusions, and SNV) were detected in 212 patients. Of the 46 patients with MET amplification, 14 (30.4%) were GC followed by CRC (N = 10, 21.7%), melanoma (N = 7, 15.2%), CCC (N = 6, 13.0%), sarcoma (N = 2, 4.3%), HCC (N = 2, 4.3%), NSCLC (N = 2, 4.3%), pancreatic cancer (N = 2, 4.3%), and gallbladder cancer (N = 1, 2.2%). All MET-amplified tumors had microsatellite stable (MSS) status and 17.4 % patients (N = 8) were TMB-high status. And, 8 of MET-amplified patients concurrently showed MET-positive protein expression by IHC (2+ and 3+). Of note, MET fusion was detected in 0.4% (10 of 2,239) of the patients. The partner gene included ST7, TFEC, LRRD1, CFTR, CAV1, PCM1, HLA-DRB1 and CAPZA2. In survival analysis, patients having MET amplification or fusion had shorter OS and PFS than the others, suggesting MET aberration was an important key factor that could determine final response results to current chemotherapy. Conclusions: Based on our comprehensive NGS survey focused on MET aberration, we identified approximately 2.1% MET amplification and 0.4% MET fusion in patients with metastatic solid tumors. They showed worse response after chemotherapy and shorter OS and PFS.

In 0.040 mol/L HCl medium,AuCl4-reacted with cetyltrimethyl ammonium bromide(CTMAB) to form a yellow CTMAB-AuCl4 associated complex,which exhibited a maximum absorption peak at 400 nm.Under the chosen conditions,gold concentration in the range of 2.5×10-6-160×10-6 mol/L obeyed Beer's law,with an apparent molar absorptivity of 5.0×103 L.mol-1.cm-1.When the relative error was less than 5%,500 times of Ca2+,Zn2+,Mg2+,400 times of Ag+,200 times of Al3+,100 times of Pd2+,Cu2+,Fe3+ and 60 times of Irdid not interfere in the determination.This method was proposed for measurement of trace gold in waste water samples without preseparation.The analytical results were in good accordance with those of FAAS method.


Researchers have built a spherical optical system that can record images from all directions around its location, giving viewers a 360-degree view of the surrounding area. The Massachusetts Institute of Technology's Research Laboratory of Electronics, along with MIT's Department of Materials Science and Engineering and Department of Electrical Engineering, developed the new technology, known as fiber webs or optoelectronic fiber arrays.


The hyper-arid Atacama Desert (North Chile) is one of the most challenging polyextreme environments on Earth due to its hyper-aridity, extreme solar irradiance, both ultraviolet radiation (UVR) and photosynthetic active radiation (PAR), high day/night temperature fluctuations and, in some cases, high salinity. Despite the combination of extreme environmental conditions, microbial life has found a refuge in endolithic (inside rocks) microhabitats, as in other arid deserts, in diverse lithic substrates (gypcrete, granite, calcite, gypsum crust, halite and ignimbrite). Endolithic microhabitats are constituted by a network of pores and fissures connected to the surface within semi-translucent rock known to provide protection from lethal UVR and excess of PAR, as well as enhance moisture availability. Despite the fact that the light regime within rocks seems very scarce, the microbial communities in these microhabitats are photosynthetic-based, so that oxygenic phototrophic primary producers (mainly cyanobacteria) support a diversity of heterotrophic microorganisms. Due to the harsh conditions the cyanobacterial community is usually dominated by members of the Chroococcidiopsis genus, characterized by their extremely high resistance to ionizing radiation and desiccation.
The scope of this doctoral thesis is to explore the endolithic life, paying special attention to the phototrophic fraction that supports the microbial community and its adaptations strategies and acclimation capacity, by adopting a multidisciplinary approach. This main goal is addressed in four chapters.
In Chapter 1 the biogeography of microbial communities in three different endolithic microhabitats of gypcrete was investigated through a pioneering approach, on a micro scale. Microhabitat architecture was characterized using Scanning Electron Microscopy in BackScattered Electron mode (SEM-BSE) and Computerized Tomography (CT-Scan) along with the exploration of the composition and diversity of the endolithic microbial communities by means of high-throughput sequencing. These results demonstrated that microhabitats less exposed to sun radiation showed a lower diversity in the endolithic community, as well as the presence of unique cyanobacteria taxa. Thus, it was suggested that the differences in the habitable architecture of a microhabitat, even within the same piece of lithic substrate, determines microbial community diversity and composition.
Chapter 2 was focused on describing the cyanobacterial community inhabiting the hypersaline endolithic microhabitat of halite in one of the driest locations on Earth, Yungay. The morphology and ultrastructure of the obtained cyanobacterial isolates from Chroococcidiopsis genus along with the cyanobacterial aggregates was characterized by means of a combination of microscopy techniques (light, fluorescence and transmission electron microscopy (TEM)). The development of a specific DNA isolation protocol allowed to perform a phylogenetic study and describe the adaptation strategies to osmotic stress through whole genome sequencing of the Chroococcidiopsis isolated strain. The comparison of the Chroococcidiopsis isolate features with those of the major cyanobacteria observed inhabiting the halite endolithic habitat pointed to Chroococcidiopsis as the dominant cyanobacterium in the halite endolithic habitat in Yungay.
In Chapter 3, the response to UVR and PAR of Chroococcidiopsis strains isolated from the chasmoendolithic microhabitat of calcite and the cryptoendolithic microhabitat of halite was addressed. Oxidative stress was evaluated by studying Reactive Oxygen Species (ROS) accumulation, through spectrofluorometric measurements and microscopy observations, and the adaptation strategies of the cyanobacterial isolates to oxidative stress were described thanks to whole genome sequencing. In addition, the accumulation of the UV-screening compound scytonemin was evaluated through high performance liquid chromatography (HPLC) along with the metabolic activity and ultrastructural characterization studied by microscopy techniques (fluorescence microscopy and TEM). The results revealed differences in their acclimation to similar microhabitats exposed to slightly different light conditions. This suggested specific adaptation strategies related to their original microhabitat and a strain-specific environmental pressure selection.
In Chapter 4, the bioactive compounds present in four cyanobacterial strains from the Chroococcidiopsis and Gloeocapsopsis genera isolated from different endolithic microhabitats and lithic substrates were explored. Bioassays (antibacterial and cytotoxicity), liquid chromatography tandem mass spectrometry (LC-MS/MS) and genomic tools (identification, annotation and analysis of secondary metabolites gene clusters-antiSMASH) were used to determine the actual and potential activity of each strain. The results showed a large number of compounds actually and potentially produced by the studied cyanobacterial strains with weak antibacterial activity and important cytotoxic activity against cancer cells. This suggests that cyanobacterial strains from this polyextreme environment constitute a promising source of natural products of biomedical interest.
The set of results presented in this thesis suggests the importance of a "micro" perspective when analyzing the distribution and composition of microbial communities colonizing such a restrictive microhabitat as the endolithic. The microenvironmental conditions in each microhabitat and substrate and the specific biotic interactions determine the whole selection of genotypes and phenotypes able to colonize efficiently each microhabitat and lithic substrate in a polyextreme environment.
This thesis, which aims to understand the ecology and behavior of endolithic microbial communities in extreme environments, encourages further studies towards understanding the limits of life, offering a new perspective on environmental selection due to the abiotic and biotic factors that occur in a microhabitat as particular as the endolithic.


We describe an experiment designed to understand the X-ray security screener task via investigation of how training environment and content influence perceptual learning. We examined both perceptual discrimination and the presence/absence of clutter during training and how this impacted performance. Overall, the data show that performance was generally better when there were clutter items in the training images. We also examined the diagnosticity of a measure of cognitive efficiency, a combinatory metric that simultaneously considers test performance and workload. In terms of cognitive efficiency, participants who trained in the difficult discrimination with clutter present experienced lower workload during the test relative to their actual performance. The discussion centers on how improved analytical techniques are better able to diagnose the relative effectiveness of training interventions.


• Given the discriminatory exercise of the law, compounded by a lack of sufficiently qualified and trained judges and prosecutors, an international consensus soon gelled around the need to introduce internationals into Kosovo's legal structure. In early 2000, UNMIK broke with international precedent and appointed one international judge and one international prosecutor to the Mitrovica district court, one of the five district courts in Kosovo.


We recently published data on an unusual case of chronic spongiform encephalopathy with kuru plaques and its serial transmission to mice and rats [2]. The protracted clinical course of four years as well as peculiar pathological findings in the patient were unusual for Creutzfeldt-Jakob disease. Therefore

Aim. This study aimed to assess the domains of patient safety culture issues at Rajaie Cardiovascular, Medical and Research Center in 2012. Background. Patient safety is a critical component of health care quality. As health care organizations con-tinually strive to improve, there is a growing recognition of the importance of establishing a culture of safety. Method. This descriptive analytical cross-sectional study was conducted in Rajaie Cardiovascular, Medical and Research Center. Multi-stage random sampling, proportionate to the number of the hospital staff., was used to recruit the participants. The sample consisted of the physicians, nurses, and laboratory personnel. The questionnaire "Hospital Survey on Patient Safety Culture" was used to collect the data. Findings. The total mean score was 65%. The highest score was achieved by the paraclinical and diagnostic departments in the issue of team-work within organizational units (83%), and the lowest score belonged to the paraclinical and diagnostic departments in the issue of error occurrence (42%) and the in-tensive care units in the issue of staff affairs (42%). Conclusion. Overall, the assessment of patient safety culture in a hospital can serve various purposes, not only can it evaluate the status of patient safety culture in that hospital and identify its strong and weak points, but also it can raise the awareness of the staff vis-à-vis this significant issue and thus improve it. Those aspects of patient safety culture that scored less than 60% need augmentations.


The occurrence of natural hemagglutinins in the coelomic fluid of sea urchins, Anthocidaris crassispina, Pseudocentrotus depressus, and Hemicentrotus pulcherrimus, was reported.The coelomic fluid preparations from three species of sea urchin were found to have hemagglutinating activity against rabbit and human erythrocytes but not against mouse and sheep erythrocytes so far examined. Dog erythrocytes were sensitive to the coelomic fluids of A. crassispina and H. pulcherrimus. The coelomic fluids of P. depressus and H. pulcherrimus also agglutinated guinea pig erythrocytes.The hemagglutinins against rabbit erythrocytes from A. crassispina and P. depressus might be a protein or a protein-like substance and were heat-unstable and resistant to trypsin digestion, but not to bromelain, and were affected by 2-mercaptoethanol though the activity of the former was recovered when 2-mercaptothanol was removed. On the other hand, the hemagglutinin of H. pulcherrimus might be a large molecular, complicated carbohydrat...


Jammu And Kashmir State is well known for its charming scenery. There are beautiful springs, lakes, rivers and their tributaries. All these add to its scenic beauty. The lakes of Kashmir valley are bounded on all sides by Himalayan Mountains. These lakes are irreplaceable natural water bodies' abiding a rich and diverse gene pool. Lakes of the Jammu and Kashmir state are on among the most attractions of the tourists of the planet. A thorough study encompassing all environmental aspects, including socioeconomics, needs to be undertaken so as to frame an ecologically well balanced conservation strategy for this important aquatic ecosystem of the region. However, once beautiful water body has been the worst victim of the anthropogenic pressures during the second half of the 20th Century and has undergone tremendous ecological changes. In spite of innumerable conservation measures taken by the management authorities over the past two three decades, the ecological condition of the lake has deteriorated and it is getting enriched with plant nutrients and other pollutants, becoming more and more infested with macrophytes, getting slowly shallower and shallower and shrinking gradually in size.


Abstract : Current USAF avionics acquisition practices breed 'black box' proliferation with all its attendant high costs, low reliability, and heavy O+M burden. This is happening while digital technology threatens to inundate the Service Logistic channels. Enough technology is in hand to create prototype 'digital avionics'. Software turns out to be the single most deficient technical area. The board concludes that properly exercised avionics General Systems Engineering (GSE) can cause the much needed turn about in this avionics situation. The board has identified practices and facilities needed to adequately conduct avionics GSE (Chapters II, III, and IV). The Board recommends a modest investment of approximately 10 MTS, to initiate a 'full spectrum' GSE capability at ASD, the principal USAF aircraft weapon engineering center. Certain prerequisites mandatory for the success of the GSE organization have been identified by the Board. These are (1) need-to-know, (2) organizational GSE expertise, and (3) an outlet for GSE organization's guidance and advice to, and among the SPO's. The Board recommends careful monitoring of the growth of the avionics GSE capability by the Commander ASD. (Author)


ABSTRACT Four new fully triphenylamine-based polyamides coded as polyamide (CF3,CF3), polyamide (CF3,CH3), polyamide (CH3,CF3), and polyamide (CH3,CH3) were synthesized by the phosphorylation polyamidation reaction from various combinations of 3,5-bis(trifluoromethyl)-4′,4″-dicarboxytriphenylamine, 3,5-dimethyl-4′,4″-dicarboxytriphenylamine, 3,5-bis(trifluoromethyl)-4′,4″-diaminotriphenylamine, and 3,5-dimethyl-4′,4″-diaminotriphenylamine. All the polyamides were amorphous and readily soluble in many common organic solvents and could be solution-cast into transparent, flexible, and strong films with good mechanical properties. They had useful levels of thermal stability associated with high glass-transition temperatures of 268–287°C and 10 wt%-loss temperatures in excess of 500°C. Cyclic voltammograms of the film of polyamide (CH3,CH3) on the indium-tin oxide-coated glass substrates exhibited two oxidation redox couples with E1/2 around 0.82 and 1.29 V vs. Ag/AgCl in tetrabutylammonium perchlorate/acetonitrile solution, accompanied by a color change from pale yellow neutral state to dark green oxidized state. The CF3-substituted polyamides displayed a higher oxidation potential and less electrochemical stability as compared to the CH3-substituted analogues. GRAPHICAL ABSTRACT


The High Luminosity LHC (HL-LHC) will start operating in 2027 after the third Long Shutdown (LS3), and is designed to provide an ultimate instantaneous luminosity of 7:5 × 1034 cm−2 s−1, at the price of extreme pileup of up to 200 interactions per crossing. The number of overlapping interactions in HL-LHC collisions, their density, and the resulting intense radiation environment, warrant an almost complete upgrade of the CMS detector. The upgraded CMS detector will be read out by approximately fifty thousand highspeed front-end optical links at an unprecedented data rate of up to 80 Tb/s, for an average expected total event size of approximately 8 − 10 MB. Following the present established design, the CMS trigger and data acquisition system will continue to feature two trigger levels, with only one synchronous hardware-based Level-1 Trigger (L1), consisting of custom electronic boards and operating on dedicated data streams, and a second level, the High Level Trigger (HLT), using software algorithms running asynchronously on standard processors and making use of the full detector data to select events for offline storage and analysis. The upgraded CMS data acquisition system will collect data fragments for Level-1 accepted events from the detector back-end modules at a rate up to 750 kHz, aggregate fragments corresponding to individual Level- 1 accepts into events, and distribute them to the HLT processors where they will be filtered further. Events accepted by the HLT will be stored permanently at a rate of up to 7.5 kHz. This paper describes the baseline design of the DAQ and HLT systems for the Phase-2 of CMS.


CHD now constitutes nearly 80% of all cases of heart disease encountered during pregnancy in developed nations. This study was undertaken to assess the obstetric and fetal outcome in pregnant women with CHD. A total of 41 pregnant women with CHD were included in the study irrespective of gestational age and parity. The subjects were followed up for mode of delivery and fetal as well as maternal outcome. Majority of women were between 20 to 25 years of age [61%], were nulliparous (75%), had no history of abortion (80%) and most had no living children. Majority of the pregnancies were unbooked at the antenatal clinic of Safdarjang Hospital [53.7%]. A total of 32 [78%] pregnancies were completed successfully. The postpartum period was uneventful in 25 cases while there were concomitant medical disorder in 9 cases and 7 cases developed complications. The only factor that was significant (p-value=0.001) was birth weight amongst successful deliveries. In general, pregnancy was sufficiently well tolerated in women with milder forms of CHD.


Background: Prior to the development of the Journal of Vascular Societies Great Britain & Ireland (JVSGBI), there were limited opportunities for UK based vascular health professionals to publish research relevant for UK vascular practice. A survey was developed to evaluate the appetite and potential infrastructure for a UK vascular journal amongst vascular healthcare professionals. Methods: In May 2020, an online questionnaire was administered by The Vascular Society of Great Britain and Ireland (VSGBI) Research Committee, surveying vascular health professionals regarding the development of a UK-specific vascular journal. The survey was disseminated via email to multi-disciplinary members of the vascular community with links promoted on social media. Results: Responses were received from 359 individuals identifying predominantly as surgeons (38%), nurses (8%), technologists (10%), radiologists (20%), trainees (10%), physiotherapists (7%) and other (7%). The majority of participants (67%) indicated they would be in favour of a UK-specific vascular journal and that it should be available as an online quarterly publication. Almost three quarters (74%) of respondents thought a subscription fee should be included in societies' membership fees. Free text comments highlighted a few concerns, suggesting the focus should instead be to improve the quality of existing vascular journals. However, most respondents welcomed the idea of a journal relevant to UK practice, with inclusivity of all UK vascular professions to encourage more collaborative working. Conclusions: Overall, feedback collected from the survey was positive and suggested a demand for a UK-specific vascular journal, providing an indication that the development of such a journal should be further explored. The results of this survey helped to inform the development of the JVSGBI.


Objective To understand incidence of infants' ocular disease, whose birth weight are over 2000g and assess necessary to carry out ophthalmic screening. Methods Using indirect ophthalmoscopy and(or) RetCam Ⅲ, we screened 636 children born in 2012 for various fundus diseases. 636 cases of neonatal were divided into two groups(gestational age over 37 weeks or less 37 weeks). And the happenings and treatments of various fundus diseases were compared. Results The total probability of fundus diseases that neonatal birth weight greater than 2000g is 12.89%. The most common diseases of the children are retinal hemorrhage(8.65%), ROP(2.20%) and vitreous opacity(0.94%). Conclusion Retinal hemorrhage is common disease among the children, with higher incidence rate of natural born spontaneously than that of cesarean.It is necessary to carry out retinal screening and follow-up visit for the children.


Goal understanding is the process by which interactants make inferences about others' objectives during conversation. Previous research has examined goal understanding without concern for the timing of goal pursuit. Accordingly, an experiment examined the timing of pursuers' efficiency in the communicative behavior employed to reach their goal. Results indicated that timing modified the relationship between pursuers' efficiency and detectors' accuracy and to a lesser extent detectors' certainty. Efficiency was positively correlated with accuracy for the initial minute of a 5-minute interaction but not subsequent minutes.


We estimated numbers of persons, born between 1950 and 1985 in Japan, who were persistently infected with hepatitis B virus (HBV) through vertical and horizontal infections.


Gregory arrived in Melbourne, without his family, and was welcomed by the Professorial Board on 23 February 1900. He probably stayed initially with the Professor of Biology, Walter Baldwin Spencer (1860–1929), an enthusiast for fieldwork, who had written to him offering the use of his house as his wife and children were away (letter with A. Mendell). He must have made a favourable impression amongst the academic community because he was awarded a Melbourne University DSc almost immediately by ' ad eundem gradum ' (Univ. Melb. Archives). This was not an honorary degree but recognition that he had achieved the same degree in another university of repute, in this instance, London. Of course, since his 1893 London DSc, he had published more than enough to gain another DSc if he had chosen to apply.

According to Lim (1975), his duties were to devote the whole of his time to the work of his department; to conduct and mark examinations and to deliver two courses of lectures of three hours a week each and associated fieldwork instruction. According to the newspaper The Age of 26 February 1900, Gregory's predecessor at Melbourne (who had come from a Chair at Queen's University, Belfast to the Chair in 1854, initially taught almost all the science in the university), 'the late Sir Frederick McCoy never took his students into the field at all so they had no such practical work or contact with mining in the colony whereas Dr Gregory intends to promote field work, mineralogy, links with mining and palaeontology teaching in geology, especially as regards the sequence of beds' (Fig. 13.1).

A strike-oriented trend of Wilcox oil and gas production in central Louisiana marks the location of an early Tertiary clastic shelf-margin. The shelfmargin contained a central unstable region flanked by two stable regions. The stable regions occurred where there was no significant progradation beyond the location of the underlying shelf-margins. Conversely, the unstable region occurred where progradation extended basin ward of the underlying shelfmargins. Seven depositional sequences can be recognized within the shelfmargin. The vertical arrangement of these sequences shows that migration of the margin was negligible throughout Wilcox deposition, thereby suggesting a balance between subsidence and deposition. Through numerical simulation, it was concluded that published values for global cyclic sea-level fluctuations cannot be used to account for the development of these sequences. Rather, a sea-level which experiences variable rates of fall over a 0.5 x 10® year interval could account for the origin of such sequences. A shale-filled submarine canyon system occurs within the unstable region of the margin. Morphologically, the canyon cross-sectional profile resembles that of an entrenched fluvial system. Conventional cores through sandstone bodies from stable and unstable regions of the margin exhibit similarities in vertical sequence and interval thickness. Both sandstone bodies represent truncated progradational shoreface sequences v/hich were associated with shelf-margin deltas. A computer program (DEPSIM) was developed in order to account for a significant difference observed between transition zone facies of the two


Sandwich plates with truss cores have been assumed as a sandwich panel with uniform cores.Then the bending deflection of sandwich plates under local loads were studied with Reissner sandwich panel theory by means of the Fourier series expansion.The closed-form solution of a simple supported sandwich plate was calculated,and it agreed well with 3D finite element analysis.


The embedded Bayesian networks (EBN) introduced in this paper, are a generalization of the embedded hidden Markov models previously used for face and character recognition. An EBN is defined recursively as a hierarchical structure where the "parent" node is a Bayesian network (BN) that conditions the EBNs or the observation sequence that describes the nodes of the "child" layer. With an EBN, one can model complex N-dimensional data, avoiding the complexity of N-dimensional BNs while still preserving their flexibility and partial scale invariance. In this paper we present an application of the EBNs for face recognition and show the improvement of this approach versus the "eigenface" and the embedded HMM approaches.


In this research, the jet-flow characteristics under tank pressures of 2 ∼ 6 kgf/cm2 were studied to obtain basic data for an optimal design of the main nozzle in an air- jet loom. Furthermore, wefts were actually inserted in the nozzle and weft traction forces were measured. Axial changes of the nozzle jet speed and jet diameter below the tank pressure at which choking arises at the exit of the acceleration tube are largely different from those above that tank pressure. Choking arises within the upstream region in the acceleration tube (Mach 1), and the Mach number at the tube exit exceeds 1. When this happens, expansion waves occur owing to underexpansion, and the oscillation of compression and expansion waves can be seen in the downstream region. Therefore, the weft drag force F, which represents the weft-flying property in a nozzle, increases in proportion to tank pressure PT. But when the flow is choking at the exit of the acceleration tube, the drag force F becomes nearly constant, even at higher tank pressures.


The edges are one of the salient features in an image and they are essential for multispectral image processing. But existing compression standard JPEG2000 produces visual artifacts in reconstructing an image at high compression ratios (CRs) because they do not tailor about the high frequency components, i.e. detailed information like edges and other geometrical features. So, this work intends to preserve detail or edge information of the reconstructed image without any penalty in compression performance. The proposed method deals with principal component analysis and extended shearlet transform for spectral and spatial decorrelation, respectively. Thresholding is applied to transform coefficients and the threshold output is encoded by set partitioning in hierarchical tree coding technique. The simulation result shows that the proposed method is more efficient than existing conventional method like JPEG 2000; for a wide range of geometrical features of the images. The performances of the proposed method are measured by both rate–distortion and information preservation perspectives. The rate–distortion performance measures are CR, peak signal-to-noise ratio and mean structural similarity index metric. The information preservation measure is kappa coefficient which is obtained from classification of reconstructed image.


The compound of rare ginsenoside Rh_2 and Rh_3 are obtained by enzyme hydrolysis from proropanaxtiol saponins.Ginsenoside of pure Rh_2 and crude Rh_3 are separated by ordinary silica gel column gradient elution.The Rh_3 monomer is further achieved by high-pressure silica gel column separation,with the purity over 95%.


: Short videos are becoming more popular in mobile Internet age. Not only people's media consumption patterns have been changed by the rise of this new media form, but also it has posed challenges to public psychological well-being. For many netizens, their entertainment needs have been met by watching short videos. However, many side effects, such as addiction and anxiety, reduce users' subjective well-being instead of satisfying the entertainment motivation after watching short videos. Therefore, it has become a significant research problem in short videos to figure out how to get audiences to watch short videos on a regular basis while avoiding side effects like anxiety and addiction and improving audiences' subjective well-being. Based on the theory of Internet addiction, this study analyzed short video users using the 2x2x2 research method and explored the relationship between the length of use, addiction, anxiety, and subjective well-being of short video users. The results showed that short video users with different usage lengths showed significant differences in addiction, anxiety, subjective well-being, and online social support; innovative different short video users showed significant differences in addiction and anxiety, as well as a triadic relational interaction of short video users' anxiety under the interaction with self-efficacy and online social support. This study contributes to the advancement of internet addiction theory research and application, assisting short video users in avoiding addiction and anxiety, and improving the subjective well-being of short video users, thereby promoting the growth of the short video industry.


Many coaches and sport scientists still believe in a value of model champion (champion profile). Of course, it is known – or should be known – that very often it is difficult to notice the obvious thing. So, many coaches and sport scientists do not notice that great coaches, especially in combat sports, although display certain common traits, do differ considerably in their views, motivation, programming, conducting the process of training, and style of leadership. Often they try to dispute a simple truth. It is enough to compare best fencers, team players, to notice great differences in body build, type of personality (extravert or introvert), traits of temperament, functions of sympathetic and para-sympathetic system, range and variety of actions they apply in competitions, as well as variety of achievement motivation. The greatest fencers, medallists of Olympic Games and World Championships, achieve their successful results not because they have champion profile traits, but because they developed their strong points to the highest level. The other aspect of what brings success in sport is notice what happens in competitions, which type of achievement motivation is best, how the competitors learn and apply various actions in competitions. So, it is obvious that programme of fencer's training ought to be based on what happens in competition and takes into account the fencer specific personality traits. © Idōkan Poland Association "IDO MOVEMENT FOR CULTURE. Journal of Martial Arts Anthropology", Vol. 11, no. 4 (2011), pp. 48–56 Time and quality of work will provide better results than selection based on any champion profile; we don't select champions, they select themselves by work, passion and determination to achieve the highest results.


In the Cowlishaw Collection of the College Library, there is a little book by an anonymous author entitled "Some Sketches of Impostures, Deceptions and Credulity". In a series if 26 chapters the author covers a variety of subjects including oracles, false messiahs, vampirism, malingering, medical delusions and many others.


We present broadband capacity snapshots as well as grid measurements derived with a fast 5times5 MIMO channelsounder in a typical, large-scale, non-mobile, in-room office scenario where we focus on line-of-sight (LOS) transmission channels. The accessible MIMO capacity is compared to its theoretic counterpart which would have been obtained if only the LOS signal without any reflections was considered. Our premise is to enable the user of quantifying the LOS signal's impact on the overall channel capacity for the particular scenario and coinciding to demonstrate the LOS's beneficial effect for the capacity. For a huge amount the beneficial effect of the LOS signal has to be ascribed to its receive signal power increase, an advantage which can hardly be balanced by any measures in the non-LOS case. The results generally indicate the overall capacity staying fairly high even for single channel matrix realizations and widely independent from the current geometric antenna assembly. Besides, strong variations over frequency are observed. These variations are shown to be slightly reducible by rising the number of antennas, but more efficient, larger bandwidths seem to be an appropriate measure for stabilizing the overall channel capacity per bandwidth unit


In the current study, in order to obtain a thick film thickness under zero entrainment velocity at low surface velocity, the effects of ambient viscosity, pressure–viscosity index of the lubricant, and the surface waviness are investigated numerically based on a thermal elastohydrodynamic lubrication mathematical model. The increasing ambient viscosity and modest waviness can deepen the dimple by a stronger "temperature-viscosity wedge" effect. With the combined effect of ambient viscosity, pressure–viscosity index, and surface waviness, a small centralized dimple in smooth contact evolves into a big classical one together with the disappearance of the former thin droopy film thickness.


The main objective of this research paper is to observe whether the selected Indian Banks are running any CRM program to encourage customers to use of Net Banking, Mobile Banking, SMS Transaction Alerts, Credit / Debit Cards, E-Statement mailers etc and whether the selected Banks run any CRM program to obtain customer feedback regarding the Quality of IT Related services of offered by the Bank. This was pursued by conducting structured interview of branch heads of the selected 16 scheduled banks of Meerut (U.P.). The researcher with the help of a questionnaire inquired from the branch heads of selected banks and compared the responses with the desired state using GAP Analysis Worksheet. The study indicated that the most of the banks selected by the researcher in his research are having CRM (Customer Relationship Management) program to encourage use of Net Banking, Mobile Banking, SMS Transaction Alerts, Credit / Debit Cards, E-Statement mailers among customers. The study also indicated that the most of the public sector banks selected by the researcher in his research are not running any CRM program to obtain customer feedback regarding the Quality of IT Related services, whereas most of the private sector banks selected by the researcher in his research are running such a CRM program to obtain customer feedback.


A new family of nonlinear digital convolution filters is described having unusual and valuable properties. The response is constant phase over the entire input frequency range and, in some forms, no signal whatsoever is passed beyond the cutoff frequency and side-lobes are identically zero. By simply iterating the transform upon which a Ξ-filter is based without changing the size of the convolution kernel, the cutoff frequency may be varied. Use of Ξ-filters is analyzed and demonstrated as applied to ultrahigh-speed image processing using table-lookup computation.


In several parallel distributed processing systems, processors are connected on the basis of interconnection networks. The topological structure of an interconnection network can be modeled as a loopless undirected graph G = (V,E) where V is the vertex set and E the edge set of G. For a vertex subset V' ̃ V of graph G, the subgraph of G induced by V', denoted by G[V'], is a graph with vertex set V' and all the edges of G with both ends of vertices in V'. An m-induced subgraph of a graph is such one which induced by m vertices. A maximum m-induced subgraph of a graph G, denoted by Vmaxm (G), can be defined as Vmaxm (G) = {G[V'] | maxV'̃V,|V|=m |E(G[V'])|. The results of maximum m-induced subgraph can be applied to the measurement of fault tolerance and bandwidth of networks, and also relate to electromechanical or optical sensors. Abdel-Ghaffar has shown the maximum m-induced subgraphs on the n-dimensional hypercubes in 2003. In this paper, we investigate in constructing the maximum m-induced subgraphs and working out the number of edges of the maximum m-induced subgraphs on the n-dimensional crossed cubes.


A trivalent tris-(alkylenediynoic acid) is developed as a new monomer to prepare a poly(tris-(diacetylene)). Alkylenediynoic moieties, covalently linked to the gallic acid, lead to a high propensity for polymerization, resulting in blue poly(tris-(diacetylene)), within less than 20 s of UV irradiation as aq. vesicle solution and as thin film. The vesicle undergoes reversible thermochromism between room temperature and 95 °C. The corresponding chromism changes are blue-to-red-to-orange during heating and reverse on cooling. This reversible chromism also occurs to thin film between room temperature and 220 °C. The polymerized aq. vesicle exhibits pH-induced chromism in the alkaline range. In order to identify polymerization-induced chromatic transitions beneficial to a biosensing process, derivatization of the monomer with α-d-mannopyranoside moieties is conducted. Chromatic properties of sugar-derivatized tris-(alkylenediynoic acid) vesicle are established first. Poly(tris-(diacetylene)) vesicles, prepared from either pure or mixed monomer systems, exhibit blue phase, which do not undergo change in chromism when the sugar–lectin interaction is initiated. Whereas, when the monomer vesicle is prepared in the presence of the lectin and polymerized subsequently, chromism of the resulting poly(tris-(diacetylene)) solution is pink, as a result of ligand–lectin interaction. The chromism change can be conducted at ≈10 × 10−6 m each of both vesicle and the lectin.


Thyroid orbitopathy (TO)—also known as thyroid eye disease, thyroid ophthalmopathy, Graves eye disease, Graves ophthalmopathy, Graves orbitopathy—is an autoimmune inflammatory condition associated with classic clinical findings of exophthalmos, restrictive strabismus, and eyelid retraction.1,2 While TO is typically associated with Graves hyperthyroidism, TO can manifest in other abnormal thyroid states (eg, primary hypothyroidism, Hashimoto thyroiditis) and can even be seen in euthyroid patients.2 The pathogenesis is complex and is yet to be fully understood, making management challenging. Herein we review the disease in detail including the pathogenesis, clinical features, diagnosis, treatment as well as quality of life (QOL) and economic considerations.

Part II of this paper compares the aerodynamic damping of a modern Low Pressure Turbine (LPT) interlock bladed-disc to the one obtained when the blades are welded in pairs through the lateral face of the shroud. The damping is computed using the linearized Reynolds averaged Navier-Stokes equations on a moving grid. It is concluded that the increase in stability of the welded-pair with respect the cantilever configuration due to the modification of the mode-shapes, is smaller than the one due to the overall raise of the reduced frequencies of a bladed-disc with an interlock design. The modification of the flutter boundaries due to mistuning effects is taken into account using the reduced order model known as the Fundamental Mistuning Model (FMM). It is shown that the modification on the stability limit of a interlock bladed-disc is negligible, while for a welded-pair configuration an increase of 0.15% on the critical damping may be expected. Two realistic welded-pair bladed-discs are analysed in this work. It is shown that both are aerodynamically unstable, which is in agreement with the experimental observations. Critical reduced frequency stability maps accounting for mistuning effects are derived for both, freestanding and welded in pairs airfoils. The airfoils are assumed to be identical and mechanically uncoupled. The stabilizing effect of mistuning is also retained in these maps.Copyright © 2004 by ASME

A simplified but significantly nonlinear model is used for the short-period longitudinal flight control problem, with c* taken as the output. Uncertainty is included in the model by allowing for a large range in velocity and air density, without any provision for their measurement. The output c*(t) is to lie within specified bounds in response to a range of step commands. A recent exact design technique for uncertain nonlinear systems is used. In this technique, the nonlinear plant set is replaced by a linear time-invariant plant set, which is precisely equivalent to the nonlinear set with respect to the problem tolerances. The design execution then involves frequency response concepts and techniques. For a large problem class, the resulting design is guaranteed to solve the problem for the specific class of inputs posed. The design was simulated with excellent results. a *( C/y C* F(s) G(s) Iy J k Iti L(s) £ m mp nmp P(s) (P q = 6 r(t) R(s) s S T(s) 3 3,


An OFDM system is deliberated for various modulation schemes like BPSK, QPSK, 8PSK, 16PSK, QAM to uncover the preeminent permutation with OFDM technology. This work is carried out over the Rayleigh- and Rician- channels with additive white Gaussian noise (AWGN) for various normalized signal-to-noise ratio (SNR) values. Furthermore, number of errors measurement is also premeditated to assess the system performance along with the best combination to be used in wireless systems. The work simulated in this paper comes out with some new and brief results under different channel conditions. Our simulative results recommend BPSK+OFDM to be implemented to provide best spectral efficiency with an alternative of QPSK+OFDM under worst channel conditions for Rayleigh channels. For, Rician channels, BPSK is recommended under poor- and good- channel conditions. Under best channel conditions, BPSK and 8PSK outperforms. This work also present the impact of number of subcarriers over the BER of the system and has been revealed out that BPSK, QPSK and 8PSK offer better spectral efficiency by increasing number of subcarriers up to a certain level under best channels conditions for Rician channel.

The interface between the semiconducting polymer and the gate dielectric is one of the most critical regions of a polymeric thin film transistor. For polymeric TFTs, it is difficult to disaggregate the contributions of the electronic structure of the semiconductor and that of the dielectric because, in part, the microstructure of thin films of semiconducting polymers is strongly affected by the chemical functionality at the surface of the dielectric. We have developed a lamination technique that can be used to transfer semiconducting films formed on surfaces that yield films with high mobility to other dielectrics. We have studied films of semiconducting polymers, such as poly[5,5'-bis(3-dodecyl-2-thienyl)-2,2'-bithiophene] and poly(3-hexylthiophene) using this method. The effects of self-assembled monolayers (SAMs) formed on inorganic dielectrics on device performance are discussed. Our results suggest that mobility is mainly controlled by the structure of the semiconducting film and that the threshold voltage of TFTs may be modified through the use of SAMs.


Semiconductor heterogeneous nanocomposites have enhanced the photo catalytic degradation efficiency of photocatalysts. (Ag, Mg) co-doped ZnO nanocomposites prepared by co-precipitation method were systematically characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), ultraviolet-visible absorption spectra (UV) and Fourier transform infrared spectroscopy (FTIR). XRD pattern indicates that the pure ZnO and (Ag, Mg) co-doped ZnO possess crystalline behaviour and exhibits wurtzite hexagonal structure with average nanoparticle size has been calculated. The optical properties of the as-prepared nanocomposites were studied using UV–visible and the band gap of (Ag, Mg) co-doped ZnO is calculated to be 3.69, 3.67 and 3.63 eV that have decreased from bandgap of 3.81 eV of pure ZnO. Co-dopants shift the absorbance of ZnO to the visible region. The optical absorption edge shifted to higher wavelengths and observed blue shift in (Ag, Mg) co-doped ZnO nanocomposites. The photocatalytic studies of nanocomposites showed to enhanced degradation of methylene blue with (Ag, Mg) co-doped ZnO nanocomposites compared to the pure ZnO.


This paper proposes a class of Markov models of social mobility with duration memory. Several new duration memory structures as well as existing models, such as the Cornell model, are shown to be special cases of the general model. The model is also extended to heterogeneous populations thereby permitting age specific variants. Alternative axioms to cumulative inertia are included, pointing to new possibilities for duration specific modeling such as futuristic "memory" for currently planned programs. Given that duration effects are widespread and quite varied, the general model provides multiple possibilities for theoretically structuring these processes.


This paper presents an example of an unsuccessful information systems development. The development failure is analyzed in case form, defined by nonuse of the system for its intended obiective and an exodus of key systems developers. Organizational deficiencies in the area of proiect planning and control are highlighted. Practitioners and academics can benefit from the analysis and avoid similar pitfalls in their own work by sharing these experiences.


One of the keys of the thought and action of Pope Pius XIth, universally venerated in his time, is to be found in his conception of Christ as king of the universe. His encyclical thought 'Ubi arcano' (1922) bears the significant subtitle : On the Peace of Christ to be brought about through the Reign of Christ. The evocation of the scourges from which the world suffers leads the Pontiff, after Pius Xth, to offer the acknowledgement of the social reign of Christ. The encyclical letter 'Quas Primas' of December 1925 intends to make the precepts already contained in 'Ubi Arcano' applied in the liturgical and pastoral order. The feast of Christ-King is settled on the last Sunday of October, so that the faithful should adopt the behaviour proper to the subjects of the Divine King. The states must conform to the Christian principles in the elaboration of the laws, the administration of justice, the teaching The thought of Pius Xlth belongs to the line of theological medial doctrines and the thought of Bellarmin (indirect power of the Church on society). These encyclical letters announce the programme which the Pontiff requires : Developmednt of 'Catholic Action', condemanation of laicism, laxism in manners, extreme nationalism, brown or red totalitarism.

Based on the meteorological data recorded at 9 weather stations of Xinyang city,Henan province from 1961 to 2013,the author analyzed the spatial-temporal variation characteristics of high-temperature damage to rice in its key growth and developmental period in recent 53 years. The results indicated that the decadal variation in high-temperature damage presented the trend of " V" shape,namely the damage was the heaviest in the 1960s and 1970s,the lightest in the 1980s,and then heavier in the1990s and 2000s. The year 2013 was the year when the high-temperature damage was the heaviest during 1961 ~ 2013,and followed by the year 1966. In spatial distribution,the high-temperature damage in Xinyang city basically revealed an increasing change tendency from west to east,and from south to north,and it occurred more in the mid-east region of Xinyang in which the planting area of rich was larger. The rice yield in 2001 and 2003 was severely influenced by high temperature,and the yield loss rate reached 35. 3% and 24. 5%,respectively. Along with the update of rice variety,the influence of high-temperature damage on rice yield was decreasing. In spite of this,the warning and defense on high-temperature damage in rice production should not be ignored.

This study aims to analyze career paths and interest in being an intensive nurse and develop problem-solving solutions by conducting interactive discussion activities to disseminate intensive unit services to attract interest in becoming an intensive nurse. The method used is a case study and analysis of results and implementation gaps with a discussion based on the literature review. The results of the career path analysis research, respondents have a D3 nursing education level (90%), 5-8 years of service (87.5%), occupy the last PK level 1-5 years (93.4%) and attend BHD, PPI training, PCNT, BHL/PALS, and basic KMB training (53.3%). Interest in being an intensive nurse (63.3%). Interest in carrying out their respective roles as caregivers, educators, and researchers (60%). In conclusion, some nurses are interested in becoming intensive nurses with the appropriate level of education, tenure, and career level and have attended basic training to become intensive nurses. However, when internal recruitment is carried out to become intensive nurses, few nurses are willing to become intensive nurses, so that still needs proper implementation.

Recent results from information theory have predicted large data rates for MIMO (multiple output-multiple input) mobile radio systems (e.g [I]). However, the achievable capacity is defined by the availability of parallel propagation channels in the multipath environment. For example, the keyhole effect [2] could reduce the theoretical capacity. Obviously, radio channel measurements are needed to investigate the development and characteristics of parallel separate propagation paths. Both detailed understandmg on the most important propagation phenomena and information on the statistical properties of the channel are needed to support the development of MIMO radio systems. Essential properties of the MIMO channel measurement systems are

Halochromic (or pH-sensitive) textile materials can give an indication of the pH of the surrounding environment by a visible colour change and can therefore act as first signal systems. A possible application of this textile pH-sensor can be found in wound dressings. In addition to the use of traditional textile materials such as cotton gauze, nanofibrous nonwovens may provide benefits in medical applications. This paper discusses the development of pH-sensitive cotton fabrics by the combination of standard pH-indicator dyes with standard dyeing processes. Also halochromic polyamide nanofibres were produced by adding the pH-indicator dyes to the polymer solution. Both approaches were found to be promising. After the immobilization of the dye on a textile structure, still a clearly visible colour change was present for most of the dye-textile systems. It should however be noted that the behaviour of the pH-indicator dye was dependent on the medium in which it is incorporated.

BACKGROUND: Reconstruction of traumatic as well as non-traumatic hind foot defects is always a challenging task. Weshare here a simple and practical protocol (working solution) to select the most suitable method for soft tissue coverage of hind footdefects, customizable for every patient. METHODS: We carried out this study, in our department on 75 cases from March 2009 to May2012. All cases with wound/defect in hind foot area were included. Majority of cases were traumatic rest included cases of malignancy,Trophic ulcers, infection. Patient's data including age, sex, site of injury, mode of injury, extent of injury (isolated or combined), ifcombined structures involved, type of wound, management of wound, wound healing time and complications were noted. Once optimalwound conditions were achieved the best possible reconstructive option was selected. The various reconstructive options include VACtherapy, Skin graft, local transposition flap, perforator based flapspedicled faciocutaneous/ muscle flaps, intrinsic foot muscles, Medialplantar artery flap and distant flaps like cross leg flap and micro vascular free flaps. RESULTS: All patients had satisfactory and stablereconstruction. They were ambulating freely by 4-6 weeks post operatively. There were few complications like patchy graft loss,peripheral flap necrosis, flap congestion, but none was serious and did not require repeat surgery. CONCLUSION: The simplified protocolfollowed by us is a practical customizable solution for difficult task of hind foot reconstruction. The choice of one or multiple techniqueswill vary from time to time from one surgeon to another depending upon his or her experience and liking.


The study on the biomass distribution and the main biological characteristics of Solenocera melantho in the East China Sea,is based on data from the professional survey quarterly of trawling of shrimp and anniversary survey.The results showed that,in the surveyed areas, its annual average catch rate was 492.4 g/h.The highest catch rate 984.4 g/h in Summer and dropped to 57.9 g/h in Winter.Its distributing areas were between 60~100 m depth layers,that is the pelagic high-salinity layer,and less in quantity in the shallower areas.Highest density areas were in 30°00′-31°00′N,125°00′-127°00′E in Summer.The breeding period appeared from Jul to Nov with its peak in Sep or Oct.The recruitment colony appeared in Aug.The colony grew faster in Spring of the next year,and the best time to catch is from Jun to Oct.To make good use of the resources,it is recommended that the species should be preserved in Spring to increase recruitment stock and make more profits.
