Abstract: Yorifumi Yaguchi is a leading Mennonite poet, both in English and Japanese. He is best known in the West for his thirty poems in Three Mennonite Poets (Good Books, 1986), but his published work in English includes nearly 300 poems in five volumes. A child of World War II, he writes poetry that bears witness to the evils of militarism from Shinto nationalism to Hiroshima, then extends to Vietnam and the aftermath of the events of September 11. But his poetry also draws upon Zen Buddhism. He is an international peace activist whose poetic friendships have included William Stafford, R. S. Thomas, Robert Creeley and Denise Levertov. His poetic and prophetic voice extends to his roles as professor, poetry editor and Mennonite pastor in Japan. While the Buddhist temple bell still sounds in his work, his commitment to peace and to the word]Word is personal, global and revolutionary. ********** Yorifumi Yaguchi, schooled in the Buddhist temple of his grandfather, trained in the Shinto Japanese nationalism of his father, and personal witness to the violations and horrors of World War II as a child in Japan, became an unlikely Mennonite in the 1960s and a pioneering voice in Mennonite poetry. He draws from the wells of Japanese haiku and Zen Buddhist meditation, and to a lesser degree from Shinto animism, but most strikingly from the international peace witness of the Mennonite church. His poems are both deeply religious and very earthy. His faith is expressed in the presence of ambiguity, pain and mystery--personal, national, existential and international. His poetry has borne prophetic witness to the evils of war-starting with the twin evils of Japanese Shinto nationalism and the American nuclear bomb, and extending to Vietnam, the cold war and September 11. But Yaguchi's work is not necessarily didactic. It ranges from the meditative styles drawn from Zen and the haiku poetic tradition to somewhat metaphysical reflections on biblical stories to biting satire to deeply personal laments. Perhaps the most pervasive characteristic of Yaguchi's poetry is the creation of a personal narrator, usually first person, who bears witness--to deep personal suffering, to the horrors of war felt at the personal level, to vague premonitions of encounter with essences on the other side of the horizon, to sudden flashes of poetic illumination, to biblical ambiguity, to an irrational faith in a compelling but often distant or unreasonable God. But his voice is finally revolutionary, bearing witness to the compelling imperative of the word/Word as peace in a world torn by violence among nations. FROM BUDDHISM AND SHINTOISM IN TIME OF WAR TO MENNONITE PACIFISM Yorifumi Yaguchi's early biographical journey is still represented most graphically in two essays. "The Bible Was Nonsense to Me" (1) was written during the early 1960s while Yaguchi was at Goshen Biblical Seminary. It tells of his radical conversion to Christianity after studying poets such as T. S. Eliot at Tohoku University, and taking graduate studies at International Christian University. Later, in "What the War Did for Me," (2) Yaguchi remembers his childhood and early adolescent encounters with U.S. bombing raids, air-raid shelters, Japanese nationalism, the Hiroshima bomb and the prostitution of some of his friends to American GIs. This poignant essay was later included, slightly revised, in the 1993 poetry collection A Forlorn Dog. (3) But his story starts well before these dramatic events. Yaguchi was bom Buddhist in 1932--in Yamoto, north of Tokyo and near the Matsushima islands famed for their inspiration of the great Japanese haiku poets. He began writing haiku as a teenager, and while he has broadened his stylistic range extensively, the haiku influence is still evident. Yaguchi's religious history borrows from three primary sources. His grandfather was a dedicated Buddhist priest whose beautiful chanting of the Buddhist scriptures in the temple is a compelling part of Yaguchi's memory, and is still heard in his poetry. …


A stability analysis of the balanced condition of a two-ball balancer for a plane rotor is presented, and the results of a parametric study of the system are included. Conclusions are drawn regarding the satisfactory operation of the balancer.


This paper presents development of a comprehensive decision support tool (eTank) to analyse and optimise a rainwater tank size. The developed tool enables a simple quantitative analysis of the expected water that can be saved based on daily water balance concept. The tool produces graphs showing cumulative yearly rainwater used, overflow and augmented townwater supply. To account for climate variability, provision has been made in the tool to analyse for a particular option in three different climatic conditions (dry, average and wet). Also, the tool enables a life cycle costing and payback period analysis of any particular tank size through the simulated expected water savings per year, initial construction costs and operational. The outcomes of eTank are compared with other contemporary online tools in regards to rainwater savings. It is revealed that most of the tools overestimate the potential savings due to not considering several influencing factors.

Immunology, which originated in the early years of the bacteriological era of the teachings of contagious diseases associated with the name of the genius Pasteur and Koch, in the early days of its development, had the content to solve the most important problems of treatment, diagnosis and specific prevention of contagious diseases. It was only a separate branch of medical and veterinary microbiology and pathological physiology. Today, the doctrine of immunity as a new branch of natural science, thanks to its unusually rapid development, has gone far beyond its original scope and is entitled to recognise the importance of an independent discipline designed to solve general biological problems.


The paper presents an analysis of Bluetooth wireless technology and the new features around Bluetooth Health Device Profile (HDP) and low power operation mode. The advantage of introducing HDP and different optimization techniques in Body Sensor Networks are also discussed in the paper. The focal point of the analysis is the achievement of high interoperability and low power consumption. Finally, a use case scenario with Bluetooth-enabled medical sensors and mobile platform for patient monitoring is presented. In the paper an analysis of Bluetooth technology and its applicability in BSN networks is suggested. The accent is put on interoperability and power-save operation. HDP profile and different optimization techniques are discussed. Finally, a use case scenario with Bluetooth-enabled medical sensors is presented.


should be tempered by awareness of several features of the study cohort. As described above, the criteria by which cases were selected for the TMAs resulted in a study cohort comprising thick, frequently ulcerated and mitotically active tumours. Furthermore, the median age of the patients was higher, and the clinical stage at diagnosis was higher in the study cohort than in the general melanoma population, or even in consecutive series of patients seen in specialist melanoma centres. In addition, desmoplastic melanomas, which were over-represented in the BAP1 negative group, were thicker tumours than non-desmoplastic melanomas. Finally, there was a short follow-up duration (median 17.6 months), which was partly due to the high proportion ( 35%) of patients who died. In conclusion, our pilot hypothesis-generating study showed that loss of expression of BAP1 occurs in a small proportion ( 5%) of cutaneous melanomas. In this study cohort of thick melanomas, BAP1 loss was more frequent in desmoplastic melanomas than in non-desmoplastic melanomas, and was independently associated with poorer DFS and MSS. Further studies are required to explore the spectrum of BAP1 expression in desmoplastic melanomas. As well, studies of melanoma cohorts that are more representative of the general population of melanoma patients (i.e., greater proportion of thinner and early-stage tumours) with long follow-up, are required to validate the prognostic significance of loss of expression of BAP1.


Abstract This study investigates the value‐relevance of the revision introduced in HKAS 40 (2004) 'Investment Property' on the presentation of changes in the fair value of investment properties. The revision follows that introduced in IAS 40 (2000) as Hong Kong adopted the International Financial Reporting Standards in 2005. As introduced in IAS 40 (2000), HKAS 40 (2004) requires that companies choosing to adopt the fair value model have to present changes in the fair value of investment properties in the income statement. Previously under the Hong Kong accounting standard SSAP 13 (2000), such changes were presented primarily in the revaluation reserve. Using both a threeday short window centred around the earnings announcement date and a 12‐month long window, this study provides evidence that investors value the HKAS 40 (2004) revision in the presentation of the changes in fair value of investment properties. Based on a sample of listed property companies in Hong Kong during 2004–2006, the results of this study show a significantly higher market price reaction and returns association when changes in fair value of investment properties are presented in the income statement. The results of this study are of interest not only to academic researchers, but to practitioners and standard setters as they assess the decision usefulness of the revised presentation.


Chlamydomonas reinhardtii Dang. is a model species for the study of H2 production because its hydrogenase has a high activity. Glucose can improve the respiration and lead to oxygen deficiency to induce the expression of hydrogenase if it is added into culture medium. In our study, we added different concentrations of glucose into cultures of C.reinhardtii and observed their effects on cell densities, chlorophyll contents, H2 productions and O2 consumptions of C.reinhardtii under light and dark. The highest cell density and chlorophyll content of C.reinhardtii culture was observed when adding 4g·L-1 glucose in normal culture. The highest H2 production was 156μL·mg-1 chl when adding 6g·L-1 glucose in normal culture, which was 6.7 times higher than that before adding glucose. However, the H2 production wasn't improved when adding glucose in the sulfur-deprived culture medium. Our results demonstrated that the H2 production of C.reinhardtii was improved when adding glucose in the normal culture medium, suggesting the potential of using C.reinhardtii in dealing with waster water containing glucose for H2 production.


This study aimed to identify the functional connectivity (FC) changes of nucleus accumbens (NAc) subregions and characterize the association of network changes and non‐motor symptoms (NMS) in Parkinson's disease (PD).


In their study recently published in Diabetes Care , Epshteyn et al. (1) found that plasma B-type natriuretic peptide (BNP) was able to discriminate between diabetic patients with and without left ventricular (LV) dysfunction, even among the subset without any clinical suspicion of heart failure. It is this last observation that supports the use of BNP as a screen for LV dysfunction among people with diabetes. Detection of LV dysfunction, an early feature of diabetic heart disease, presents an important opportunity for prevention of …

The Landau-Lifshitz equation is obtained from the Lorentz-Abraham-Dirac equation through 'reduction of order'. It is the first in a divergent series of approximations that, after resummation, eliminate runaway solutions. Using Borel plane and transseries analysis we explain why this is, and show that a non-perturbative formulation of reduction of order can retain runaway solutions. We also apply transseries analysis to solutions of the Lorentz-Abraham-Dirac equation, essentially treating them as expansions in both time and a coupling. Our results illustrate some aspects of such expansions under changes of variables and limits.

The article discusses the transformations in photography from a concept created by Andreas Muller-Phole published in European Photography magazine in 1985. Having the term Expanded Photography as starting point, the transformations and the gains in the photographic language are discussed beyond of what was initially identified by the author, analyzing the evolutions proper to the photographic code from the entry of the digital system.


Trace elements may be present in solution with positive or negative charges and in different redox state. They occur predominantly in cationic form (Pb, Cu, Zn, Ni, Cd, Hg, Cr(III), Co) but some trace elements are present in anionic form (As, Se, Cr(VI), Mo and B). In soil environments, sorption/desorption reactions on/from inorganic and organic sorbents control the concentration of metals and metalloids in solution and affect their bioavailability, leaching and toxicity. Sorption-desorption processes of elements in cationic form differ greatly from those in anionic form. These reactions are affected by many factors, such as pH, nature of the sorbents, presence and concentration of organic and inorganic ligands, including humic and fulvic acids, root exudates and nutrients. Furthermore, redox reactions, both biotic and abiotic, are of great importance in controlling the oxidation state and thus, the mobility, the phytoavailability and the toxicity of many elements, such as Cr, Se, Co, Pb, As, Ni and Cu (Kabata-Pendias, 2001; Huang and Germida, 2002; Violante et al., 2002; Sparks, 2003; Huang and Gobran, 2005; Violante et al., 2007). The aim of this presentation is to provide information on the factors which affect the mobility of trace elements. Special attention is devoted to the influence of inorganic and organic ligands, including nutrients and root exudates, on the sorption/desorption processes of trace elements in cationic and anionic forms on/from soil components, soils and selected synthetic minerals (double layered hydroxides, the so called "anionic clays"). The soil components responsible for trace element sorption include, soil humic substances, phyllosilicates, carbonates and variable charge minerals (constituents such as Fe, Al, Mn and Ti oxides, short-range ordered aluminosilicates as well as phyllosilicates coated by OH-Al or OH-Fe species whose charge varies with the pH of the soil solution). Recently, evidence on the sorption of heavy metals on microorganisms have been reported (Jackson, 1998). Soil components differ greatly in their sorption capacities, their cation and anion exchange capacities, and the binding energies of their sorption sites. Trace element sorption kinetics depend on the type of surface and trace element, but generally are rapid. Half times for bivalent cations, such as Pb, Zn, Cu and Cd, sorption on peat range from 5 to 15 seconds. Except for some noncrystalline minerals that have very high specific surface charge density with highly reactive sites, humic substances appear to have the greatest capacity for sorption of trace elements in cationic form. A body of evidence has demonstrated that humic matter and metal oxides are much more effective scavengers of trace elements in cationic form, than even the most efficient sorbent among phyllosilicates, indicating that specific sorption and other complexation processes are the dominant binding mechanisms (Jackson, 1998; Huang and Germida, 2002; Spark, 2003). Complexation reactions have the following effects: i) metal ions are prevented from being precipitated; ii) complexing agents can act as carriers for trace elements in soil solution; iii) their toxicity is often reduced by complexation.


AbstractThe anodic behaviour of copper in air-saturated solutions at 25°, 60° and 90°c has been determined by stepwise potentiortatic polarisation. In 0·01 M NaHCO3, the critical breakdown potential of the protective oxide layer is displaced to considerably more positive potentials as the temperature increases. In 0·01 M NaHCO3 containing 0·01 M NaCl, the critical breakdown potential is displiiced tornore negative values with increasing temperature, but the corrosion potential–breakdown potential difference undergoes little change. In 0·01 M NaCl, the surface film on copper is essentially non-protective, and linear Tafelplots are observed. A change in the pH of 0·01 M NaHCO3, with or without 0·01 M NaCl, from 8·6 to 7·3 has little effect on the valuesof the breakdown potentials. The significance of the results in relation to the initiation of pitting corrosion of copper in natural waters is discussed.


Abstract This article presents a manuscript that significantly enriches the textual corpus of ›Helfta Mysticism‹ with a series of hitherto unknown writings. Aside from this, it contains what is by some distance the oldest copy of the ›Legatus divinae pietatis‹, in the form of a ›special edition‹ that consists of excerpts from the known text as well as new material. This is preceded by a prologue and a florilegium which is marked in an epilogue as Gertrude's own work. We argue that the epilogue of the florilegium, the prologue and the ›special edition‹ itself were probably composed by ›Sister N of Helfta‹ herself. The article provides a full description of the manuscript (Ms 827), a breakdown of the new ›special edition‹ of the ›Legatus‹-text, and an edition, translation, and close reading of the prologue.


Flow boiling in microchannel is a promising way for removal of high heat flux. This work presents a systematic twodimensional numerical study of the conjugate effect of heat transfer in two-phase flow in a microtube subjected to constant heat flux. The fluid is assumed to be water which enters in the microtube with a preheated temperature of 373 K. It is intended to obtain the enhancement in heat transfer by taking in account the flow boiling effect. Furthermore, the effect of wall to fluid conductivity ratio (ksf), tube wall thickness to tube inner radius ratio (δsf), and inlet Reynolds number in an unsteady flow boiling of water in a microtube under constant heat flux are studied. The result indicates that the mixing of fluid layer is improved due to presence of vapor bubbles along the length of the microtube that results in improvement in overall heat transfer coefficient. The growth and motion of vapor bubble due to evaporation are observed.


The »right of priority» or »right of allocation« is among acquired rights created for a person due to taking the lead by the person in »commonalities and public property«.  By virtue of this right, in temporary use of the mentioned matters the person takes antecedence and priority over others such that others are not permitted to intrude in his or her right before his or her agreement and permission.  The reason for legitimacy of the right of priority and allocation is mainly Islamic exemplums and in some cases tradition of the wise and Muslim Jurisdiction and at times by consensus.  In theological books it has been said: «the instruments of the right of priority and allocation are: «precedence, marking the land, reviving the inanimate, lawful possession and authorization».  In other words, each of the mentioned cases by itself leads to arising of the right to take antecedence over others in taking advantage of a series of permissible matters (such as commonalities, public property and public permissions).  Yet, we see that a common element exists in all these cases which are » time precedence« and generalizing of prophetic saying (greetings to him and his family): » من سب ق إلی ما لم یسبقھ إلیھ مسل م فھو أحق بھ« Therefore precedence includes all the mentioned cases.

The earlier developed algorithm for simulating manoeuvring motion in regular waves was augmented by computation of vertical and transverse shear forces and bending moments developing in the time domain. While the integrated forces and moments affecting motions of the ship as a rigid body were estimated relatively rigorously, using the auxiliary state variables method for representation of radiation forces in the time domain, the corresponding distributed loads are calculated in a simplified way exploiting the concept of a slowly varying encounter frequency. Simulations were carried out for straight runs, turning manoeuvres and zigzags for the S-175 container ship.


The costs of making bad hiring decisions and the difficulties of getting meaningful information from reference checks of prospective employees have led many employers to use personality tests1 as part of their hiring process. Employers choose from a wide variety of tests in an effort to both weed out job candidates with undesirable traits, such as dishonesty, or tendencies toward violence or tardiness, and to judge the "fit" between the


�� One of the major problems facing the beekeeping ind ustry in Saudi Arabia is the infestation of honeybee colonies with parasitic mite Varroa destru ctor. Bee breeders strive to reduce exposure of bees to pesticides by developing stocks of bees tha t resist the mites. The goal of this study was to investigate the genetic variability of eleven colon ies representing three honeybee races namely; Apis mellifera yementica (Indigenous) tolerant to m ites, Apis mellifera carnica (Carniolan) sensitive to mites and hybrids between Indigenous a nd Carniolan moderately tolerant. These colonies were collected from the gene pool of the B ee Research Unit of King Saud University through ISSR analysis. The ten ISSR primers used ge nerated 34 polymorphic fragments and the average heterozygosity for each primer was 0.244. These data showed that most of the detected loci were polymorphic reflecting the fact that the eleven colonies under-study came from wide diverse races. Also, choosing the similar and the dissimilar fragments among all genotypes indicated clearly that the ISSR primers used in thi s study were sufficient to fingerprint the 11 colonies under-study. In addition, the average sim ilarity coefficient among the 11 colonies was calculated and it was 0.561 indicating wide range of genetic diversity with in the current gene pool of the Bee Research Unit of King Saud University ge rmpl.asm. Finally, a dendogram was generated by UPGMA method which divided the colonie s into three groups according to their origin. The first group included the indigenous co lonies, the second included the carniolan colonies and the third group was the hybrid group a nd it was between the two groups. The dendrogram demonstrated clearly the ability of the ISSR marker technique to detect the genetic variability among and within the honey bee colonies used in this study.


S. Creosotal in Pneumonia. Prof. Andrew H. Smith, of New York, (Am. Therapist, Jan uary 15, 1905) says that in discussions of pneumonia, the pneumo coccus is often,confused with the pneumotoxin. The first is a microorganism which finds a nidus in the aircells of the lungs, constituting a local lesion ; the second is generated by the first and then absorbed into the blood, giving rise to acute fever. Perhaps a majority of persons almost constantly carry pneumococci in that part of the airway which is lined with ciliated epithelium, but there the cocci do not multiply freely and are unirritating. So long as the ciliae remain active they oppose the advance of the germs to ward the aircells, where there is a pavement epithelium. .But the introduction of a single germ into the congenial nidus afforded by the air vesicle may be sufficient to set up the process ; and as the organisms multiply and the toxin' from them is absorbed into the blood, the infectious fever appears. This is prefatory to the question whether it is possible to abort or favorably influence the course of pneumonia by drugs. Are the germs in the lung and their products in the blood capable of being so acted upon by safe doses of antiseptics as to be deprived wholly or partly of their harmful effects? Many affirm, some deny, while perhaps the majority consider the question sub judice. I do not hesitate to range myself with the first class and to own to impatience with the second group. For more than a decade evi dence has accumulated to the fact that a number of substances, possessing bactericidal or antiseptic properties when introduced into the system, do influence materially the course of the disease and diminish its severity. Of these the one in which I have most confidence is creosote carbonate or creosotal. It reverses the usual proportion of crisis termination to lysis termination, so that the former,—ordinarily much the more frequent,—becomes much the less frequent. This fact has been observed by Peabody, W. H. Thomson, myself and others and can scarcely be without significance. The favorable effect of creosotal upon the mortality is testified to by a long list of authorities. The very extensive bibliography is so easily ac cessible that I will not burden this article with its reproduction. In a paper contributed to the Medical and Surgical Report of the Presbyterian Hospital for 1904, Drs. G. A. Tuttle and H. S. Carter report 600 pneumonia cases treated in the hospital during the six years ending February 1903. The mortality in uncompli cated cases was 22.8%, in complicated ones 36%, and, when con nected with other diseases, 47%. 101 cases, of which thirty were complicated, received ten minims of creosotal every two hours dur ing the whole course of the disease, in addition to the usual sym pathetic treatment. According to the ratio in the other cases, the thirty complicated cases should have given eleven deaths and the seventy-one uncomplicated ones sixteen deaths,—together twenty seven deaths. The actual number of fatalities was sixteen,—nine in complicated and seven in uncomplicated cases. The mortality in the uncomplicated cases under creosotal was therefore 7%, as against 22.8% in uncomplicated cases under other treatment. In most of the cases reported in the United States the dose of creosotal rarely if ever exceeded ten minims every two hours. My friend, Dr. W. W. Baldwin of Rome, Italy, reports to me, how ever, that he-gives as much as thirty or forty minims every three hours and has treated eighteen consecutive cases without a single death, even when the prevailing type of this disease was fatal. He never saw any disagreeable symptoms from its use. I person ally have never ordered more than fifteen minims every two hours, but should not hesitate to do so if that dose did not reduce the temperature within twenty-four hours. I know of no instance in which harmful effects were noted. Smoky urine appears, but is of no moment and negligible. It is important to begin the treatment at an early stage of the disease, so that the first exudate poured into the aircells may be impregnated with the drug and rendered an unfavorable culture medium for the germs. When once the cell is packed full with fibrin the plug will be but little affected by any remedial agent in the blood. But the early institution of the treatment is usually precluded in hospital and consultation practice. In family prac tice there is a natural hesitancy to use an unfamiliar treatment. Therefore the conditions are seldom favorable for the fullest suc cess of creosotal; nor will this be otherwise so long as the effici ency of any 'specific is dogmatically denied. Creosotal has incidentally a decided effect in preventing the formation of gas in stomach and intestines, with all the discom fort and danger attending abdominal distension. Should I my self be attacked by pneumonia, I should wish to be treated by a physician who believes in creosotal and will employ it with a liberal hand.


In the Qing Dynasty, chastity was advocated in society, but it was common to frame others up for sexual assault in the folk society. The reason can be understood as the result of the interaction between the people, local forces and the government in the judicial field of the Qing Dynasty. For common people, although the law in the Qing Dynasty punished adultery and false accusations quite harshly, they had sufficient motives and skills to circumvent legal restrictions and framed others up in the face of daily disputes where their interests were at stake. For local forces, the dual roles of mediators and makers limited their impact, and made cases of false accusations of sexual assault need to be judged by magistrates in court. For the magistrates, false accusations of sexual assault that should have been severely punished had been leniently dealt with because of the tradition of quelling the litigation and the strategy of avoiding trial responsibility. This reduces the risk cost of this act and in turn stimulates it.


Studies were performed to determine the basis for low NK activity in the spleens of SJL/J mice. In contrast to substantial boosting by IL‐2 or IFN of NK activity of spleen cells from high NK‐reactive strains of mice, no detectable effect of these citokines on SJL spleen cells was seen. When SJL spleen cells were cultured for 7 days in the presence of IL‐2, the frequency of proliferating cells was comparable to that of other strains of mice. However, the SJL spleen cells showed a frequency of NK‐cell progenitors which was at least 50 times lower than that of the CBA/J spleen cells. In addition to having no detectable effector‐cell activity, the cultures of SJL spleen cells contained suppressor cells which were able to inhibit the NK activity of spleen cells from other strains of mice. These suppressor cells did not adhere to plastic or nylon wool and were found in low‐density fractions after Percoll density gradient centrifugation. The cultured SJL spleen cells had a high percentage of cells capable of binding to NK‐susceptible target cells, which was similar to that seen in lytic cultures from other strains of mice. Thus, the suppressor activity may be attributable to competitive inhibition of the interaction of effector cells with target cells. Although several of the characteristics of suppressor cells were similar to those of cultured effector cells; they may not represent inactive or pre‐NK cells since their progenitors were Thyl+ and Asialo GM  1− whereas the progenitors of cultured effector cells in high NK strains were Thy I−. and GM  1+ . The ability to eliminate the progenitors of the suppressor cells by pretreatment of spleen cells with anti‐Thyl plus C' also suggested that the low or undetectable NK activity of the cultured SJL cells is not attributable to suppression but may be due to an inherent deficit of NK cells.


Abstract The electrochemical copolymerization process of polypyrrole (PPy) in the PSPMS precursor film has been discussed. Constant potential electrolysis and SEM experiments showed that pyrrolyl groups in the precursor were oxidized to form grafting centers and PPy grew through the film.


The actual operation of large power generators in the regional grids are reviewed by studying the static and transient levels of stability achieved while different ways of excitation are employed for large thermal power generators in the Heilongjiang grid. By purposeful optimal excitation, optimization of operating parameters and addition of PSS control, the transient and dynamic stabilities of output from the eastern grid are greatly improved, and some power generators in that region are enabled to achieve their maximum outputs.


Introduction Pulsed-field ablation (PFA) is a new non-thermal ablative approach for treating paroxysmal and persistent atrial fibrillation (AF). It provides an alternative to the conventional thermal techniques of radiofrequency ablation and cryoablation. PFA is currently performed with the Farapulse PFA system (Boston Scientific, USA), which recently received CE marking in Europe. In this study, we describe the current evidence on the efficacy, safety, and cost-effectiveness of this new technology. Methods The Early Awareness and Alert System of the Agencia de Evaluación de Tecnologías Sanitarias-at the Instituto de Salud Carlos III- identified this new ablation approach in June 2021. An early technology assessment was conducted by reviewing relevant literature published to November 2021. The literature was identified by searching PubMed, Embase, the International Clinical Trials Registry Platform, ClinicalTrials.gov, and the Cochrane Library. Results Seven relevant publications were identified, including three open-label trials for paroxysmal AF and one for persistent AF. Three studies comparing PFA with conventional thermal ablation techniques were also included. The safety results showed a lower incidence of complications (esophageal injury, pulmonary venous stenosis, pericardial effusion, and aortic injury) after PFA relative to conventional techniques. In terms of efficacy, PFA resulted in lower rates of AF recurrence in the medium and long term, compared with conventional techniques, and there were no differences in the lengths or success rates of the procedures. No cost-effectiveness studies were identified. Seven ongoing trials were identified, but no results have been published. Conclusions The current evidence for PFA in the treatment of AF showed good safety and promising efficacy. However, there is a lack of information on its effect on quality of life and the risk of death, disabling stroke, or cardiac arrest. Early evaluation of new and emerging technologies makes it possible to gather the minimum information necessary to support decisions on their inclusion in the healthcare system. In this case, based on current evidence, the widespread use of PFA is not recommended, except under a rigorous research protocol.


Data sets being managed in grid environments today are growing at a rapid rate, expected to reach 100s of petabytes in the near future. Managing such large data sets poses challenges for efficient data access, data publication and data discovery. In this paper we focus on the data publication and discovery process through the use of descriptive metadata. This metadata describe the properties of individual data items and collections. We discuss issues of metadata services in service rich environments, such as the grid. We describe the requirements and the architecture for such services in the context of grid and the available grid services. We present a data model that can capture the complexity of the data publication and discovery process. Based on that model we identify a set of interfaces and operations that need to be provided to support metadata management. We present a particular implementation of a grid metadata service, basing it on existing grid services technologies. Finally we examine alternative implementations of that service.

We demonstrate Eu, Tm and Er doping of GaN quantum dots. In Er‐doped samples, two very sharp blue lines were observed. These lines were dominant over the green lines reported in the case of Er‐doped GaN thick layers. However, intensities were very low in comparison with Eu‐doped and Tm‐doped GaN QDs. Intense blue emission from Tm‐doped GaN QDs was observed. Temperature‐dependent photoluminescence was studied, and the intensity only decreased to 27% between room temperature and 10 K. Structural studies on Tm‐doped samples showed that the kinetic role of Tm atoms was different from that of Eu atoms. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

I t has been known for many years that light can cause cis-trans isomerizations about double bonds. The interconversion of maleic and fumaric acids's is probably the best known example of this transformation. More recently, Hubbard and Wald3 have shown that light promotes the interconversion of the cis and trans isomers of retinene (vitamin A aldehyde). Irradiation of any isomer of retinene results in the identical steady-state mixture of stereoisomers. The structures of the various cis and trans isomers of retinene are shown diagrammatically in FIGURE 1.


The enantiomers of etilefrine (Effortil) were produced by enantioselective hydrogenation. The optical purity was determined by conversion with (+)-[(R)-tetrahydrofurfuryl-(1S)-camphor-10-sulfonate] to N-[(R)-tetrahydrofurfuryl]-etilefrine and subsequent separation of the diastereomers by HPLC. An animal experiment showed that the (R)(-)-enantiomer is more effective.


PBC is a cholestatic disease characterized by bile duct loss, ductular reaction and liver fibrosis. The canals of Hering (CoH) are the site of ductulo‐canalicular junction (DCJ) that maintain proper bile drainage from the liver, and contain the hepatic progenitor cell (HPC) population. CoH loss is noted in PBC and correlates with scoring. Secretin binds to its receptor (SR, expressed by large cholangiocytes) to promote biliary proliferation during cholestasis; however, during large duct damage, small cholangiocytes acquire large cholangiocyte phenotypes including SR expression. Secretin/SR expression is downregulated in late‐stage PBC; therefore, we aimed to understand the role of the secretin/SR axis during PBC. We hypothesized that secretin treatment restores DCJ through HPC activation and ameliorates liver phenotypes associated with late‐stage PBC.


The greater omentum has long been considered an element without great biological significance, a piece of inert tissue, an appendage.However, the situation has changed in the last hundred years, proved by the many studies and medicalresearchers conducted to value and enhance the importance of this human anatomical part.They say the greater omentum has a huge therapeutic potential. The variety of surgical applications can be mainly used in the revascularization of the affected areas that have lost tissue, especially soft tissue. The area of the extremities affected by any kind of accidents, with important results in the above-mentioned fields, draws an even bigger interest, since this biologic element represents a solution in many cases that in the past ended up with the amputation or shortening of the affected limb. The method approached in this paper is a literary review and its purpose is to identify and make people aware of the ethical problem that is specific to the transfer of greater omentum in order torepair the vascular tissue deficit when the extremities are affected. As a conclusion of the research, we can say that regardless of how complicated the medical intervention involving a patient and at least a limb of the medical team, the ethical aspects always delimitate the therapeutic decisions, ensuring their portability and moral reproducibility.


The investigation based on the implications of zinc in the metallurgical treatment of copper in the Toquepala Mine, present in this type of deposit, was based on the knowledge of the characteristics and geochemical behavior of zinc and Cu-Mo-Fe-As- Pb, starting from the definition of geological domains based on the domains of lithology, alteration, mineralization and presence of gypsum, arriving to determine that the geochemical characteristics are different in each geological domain, being more favorable in the concentration and recovery of copper, domains Geological characteristics of low zinc, iron, arsenic and lead elements, and also with the presence of gypsum / anhydrite contents. The correct determination of the parameters of the descriptive statistics of the elements Zn-Cu-Mo-Fe-As-Pb is fundamental to be able to characterize the domains and to make an optimal classification of the geological material for its shipment to the metallurgical plant. The knowledge of the spatial distribution of the zinc and the Cu-Mo-Fe-As-Pb elements gives a broader view of the location of the zones of greater concentration of each element in order to make a better estimation of mining resources.


With the recent advances in technology phased array ultrasonic testing (PAUT) has been widely used to overcome the challenges in inspecting complex composite parts. Though many PAUT equipment manufacturers (OEMs) integrate image display and basic processing they are not fully sufficient for faster, reliable and consistent decisions. This paper describes various analysis tools to minimize operator dependency in quantification of discontinuities that were detected and also introduces a tool for merging individual inspection files to enable global view of the component being inspected that greatly aids engineering community responsible for disposition & local repairs of the component without the understanding of PAUT inspections. It also introduces a common software platform to analyze files that are saved by different OEMs. Keywordscomposites, phased array ultrasonic testing, image analysis


Statistical tests and graphs are an important part of any immunological research publication or presentation. However, not all immunologists have the statistical expertise to choose the best methods to evaluate and represent their experiments, and the formal statistics training required by undergraduate immunology curricula is often quite limited. How can we prepare future immunologists for statistical practice in research? As a collaborative effort between the Department of Statistical Sciences and the Human Biology Program at the University of Toronto, a second-year undergraduate course was developed to integrate statistics instruction with research design to improve the quantitative training of life sciences students. In a Scholarship of Teaching and Learning (SoTL) study conducted within the course, student attitudes and self-efficacies for statistics, as well as their abilities to recognize and handle problems related to statistical practice in life sciences research, were assessed through surveys administered at the beginning and end of the course (n=126). Here, we present our team-teaching model and strategies for promoting meaningful connections between statistics and life sciences research through course design, activities and assessments. We also highlight results from our SoTL study, which revealed that 77% of students felt more confident about choosing the correct statistical procedure, while 74% indicated that the course helped increase their confidence with respect to results interpretation. We hope that insights from this teaching partnership and our SoTL findings will help inform future course offerings to better prepare our students to effectively engage with statistics in immunological research.


Since  government  is  a  nonprofit  organization,  I  apply  firm theory under zero profit condition to analyze the optimal size of  government.  Government  should  minimize  shortrun average  cost  while  demand  for  public  service  is  equal  to supply  of  public  service.  The  optimal  size  of  government implies  (1)  tax  is  minimized  under  balance  budget  given public service and (2) budget surplus and budget deficit are inefficient (i.e., balance budget is Pareto optimum)


In this paper, the characteristics and the components of coal liquefaction residue (CLR) were introduced respectively. Then, the applications of coal direct liquefaction residue was further reviewed. Finally, as for the applications of residue was analyzed synthetically in conclusion.


Left Atrial Ectopic Tachycardia. Introduction: The high posteromedial right atrium is adjacent to the left atrium near the right superior pulmonary vein. We hypothesized that analysis of electrograms at this site could distinguish left from right atrial tachycardia.


"Evans admits in passing that Derrida is often, and concerning the most crucial matters in Husserl's thought, correct" (Lawlor, "Navigating," 3). I do try to acknowledge what can be acknowledged. Do I really "admit," even "in passing," that Derrida is correct about "the most crucial matters in Husserl's thought"? The more interesting question would be whether I "admit" that Derrida is correct at the crucial junctures of his deconstruction. And when one looks at the list of "admissions," the degree to which and sense in which I "admit" that Derrida is correct would require serious qualification in a number of cases. "Evans even admits that Speech and Phenomena contains some arguments. Derrida argues, for instance, that Husserl's notion of absolute consciousness, being temporal, implies that there is no pre-expressive stratum of sense [126]" (ibid., 4). I don't get this. Absolute consciousness generally is not temporal for Husserl (as I note at Strategies, 104). Derrida's own discussion does not really thematize the notion of absolute consciousness. It is discussed in a footnote (Derrida, SP, 84/94), but it is not systematically introduced at all. "Yet, when one comes to the conclusions of his book, one finds that he provides no reminder for his readers that these admissions have been made. He never reminds his readers of the arguments' soundness; he never reminds his readers of how often Derrida says something true. Instead, the conclusion leaves the impression that Evans believes that deconstruction in general and SP in particular amount to nothing more than a poorly executed parody of classical philosophical rigor [172-73]. The omission of such a reminder, an omission that moreover contradicts Evans's explicit intention to remain open to the Derridean challenge [xviii], makes the integrity of this book questionable" (ibid.; references are to Strategies of Deconstruction). Let's move backwards. I never assert that "deconstruction in general" is good, bad, or indifferent. Quite the opposite, I am explicitly open to the possibility that other deconstructive texts do a better job than I find Speech and Phenomena and Of Grammatology doing. I also never assert-nor, I think, do I leave an impression-that Speech and Phenomena is a "poorly executed parody of classical philosophical rigor." I do make something of a big deal of considering Scanlon's (itself thoroughly tongue-in-cheek) suggestion that Speech and Phenomena is "sophisticated" parody. If the critical results of my book stand, then I think that my leaning over backward to consider the possibility that Speech and Phenomena is a parody is sort of funny. One can reject that condition, of course. As for the charge that I never remind my readers of all the sound arguments Derrida presents, in the first place, I don't accept all of those arguments Lawlor mentions, as a look at Strategies will show. In the second place, when I summed up the results of my study of Speech and Phenomena in the Conclusion, I concentrated, with complete justice I think, on Derrida's attempt at a radical deconstruction of Husserl's phenomenology. Assuming, once again, that my criticisms of Derrida's readings, interpretations, and arguments, are cogent, the news is what goes wrong, the news is again and again (always assuming that I am right) that Derrida's reading/argument/interpretation, when read carefully, fails to live up to its own standards and thus fails to establish its results. I would find it difficult to imagine a reader who, at the end of Strategies, thinks "I don't know yet if Evans is right in his claims, since I haven't yet gone back to Husserl's and Derrida's texts to check out his claims, but even if he is right in the claims he makes in the reading of SP, I can already assert that this is a book of questionable integrity." But I think that it is what Lawlor is saying in challenging the integrity of my book. Defending Husserl "Evans first tries to defend Husserl against Derrida's charge of logocentrism" (Lawlor, "Navigating," 4). …


Based on the panel data of 44 economies from 1995 to 2011, this paper uses the panel data instrumental variable method and the system GMM to conduct an empirical test on the effect of corporate income tax on net exports after controlling the endogenous problems to some extent; then using the panel threshold model, the paper explores the non- linear relationship between the two.The results show that:(1) in both developed countries and developing countries,the corporate income tax exerts a positive effect on the export trade;(2) due to the difference in trade openness, the corporate income tax on net exports show a significant threshold effect, and with the deepened openness degree, the promoting effect of the corporate income tax on net exports will gradually increase.


This work investigates the formation of blisters during annealing an Al2O3 film grown by atomic layer deposition (ALD) on Si. This blistering phenomenon is shown to occur under an external load in the presence of a tensile residual stress: the total membrane stress is a super-imposition of the residual stress of the pre-stressed film and a concomitant stress due to change of blister profile. In the case of this Si/Al2O3 system, the film is indeed pre-stressed and the hydrostatic pressure is caused by (i) the effusion of H2 and H2O and (ii) Al2O3 being a diffusion barrier.


The vegetation sequence on granitic outcrops containing Opuntia fragilis (Nutt.) Haw. was examined at three sites in southeastern Manitoba. The experimentally determined species sequence supported those in the literature: (0) bare rock – pioneer lichens, (1) primary moss mat, (2) secondary moss and lichen mat, (3) tertiary moss and lichen mat, (4) stress-tolerant ruderals, (5) stress-tolerant perennials, (6) perennial grasses, and (7) chamaephytes and phanerophytes. The primary factor determining the sequence was substrate depth, presumably because of its effect on moisture retention. The species composition of the earliest seral stages (0–3) was consistent at all three sites, presumably as a result of propagule availability and the extremely xeric nature of the sere. Variations in the species of subsequent stages may be attributed to the more restrictive dispersal mechanisms of mesic species. Local variations in vegetation scale and pattern were caused by slope, disturbance, crevices or depressions, and ...


Container ship routing problem is a special variant of vehicle routing problem (VRP) which needs a lot of attention which costs enormous amount of money per day. In this paper, two popular meta-heuristics namely genetic algorithm (GA) and simulated annealing (SA) for solving the ship routing problem have been compared. A series of experiments were conducted varying the number of ports involved and the route taken to visit these ports. These numerical experiments revealed that SA yielded more profits compared to GA as number of ports increased.


Program Description: Pediatric sinusitis is a major source of patient referrals for the otolaryngologist. The issue of diagnosis and treatment differs from the adult with regard to pathophysiology, management, and patient cooperation. This seminar will focus on the current state of drugs and devices used to diagnose and treat pediatric sinusitis. The seminar will begin with the use of devices in children to diagnose chronic rhinosinusitis or differentiate rhinitis from sinusitis. Discussion will include the use of pediatric office endoscopy, endoscopic-guided cultures, CT scanning, pH probe testing and other devices. We will also discuss how they should be used in the office on children. The seminar will then progress to the use of drugs and devices in the management and treatment of pediatric sinusitis. This discussion will include adenoidectomy and associated devices, culture techniques, balloon sinus surgery, and associated minimally invasive devices as well as traditional endoscopic surgical techniques. Further discussion will focus on various endoscopic surgical drugs and devices applied to the pediatric patient both intraoperative and postoperative. Drugs discussed for the treatment and management of pediatric sinusitis will include intravenous antibiotics, topical aerosol therapy, mucolytic agents, steroids, and intranasal packing and stents. Presentations will also occur on the pediatric patient with special issues and sinusitis such as immunologic deficiencies and cystic fibrosis. This will be a presentation based on the current literature, extensive clinical experience and case studies. Panel discussions and opinion by pediatric otolaryngologist with extensive experience will be a major part of this seminar. Educational Objectives: 1) Discuss and present drugs and medical devices currently used to diagnose and treat pediatric sinusitis. 2) Present current medical devices and techniques used to treat pediatric sinusitis in the operative setting. 3) Present current drugs and devices used to manage children with sinusitis and related medical disorders.


The photoelectric property of polyaniline (doping and grafting) modified with phthalocyanine functional group is measured.It is observed that the absorption of polyaniline doped with Cu-sulfophthalocyanine and grafted with Cu-chioric-sulfonic-acid-phthalocyanine (Cu-CSAPc) is very strong in the range of visible light and near-infrared by UV-vis spectrum.The number of photogenerated carries is obviously increased while the tablet or film of polyaniline modified with CuPc functional group is illuminated.The photocurrent as high as 10 mA(at voltage of 0.5 V) can be obtained while polyaniline grafted with Cu-CSAPc is illuminated. It shows that the photoconductivity of polyaniline with CuPc functional group is greatly improved.


An active balance circuit based on the topology of flyback transformer is proposed in the article for the balance management of high capacity Lithium-ion battery packs in space. The circuit can control the value of the balance current by fixed duty cycle control, to achieve balance function for Lithium-ion battery packs. Compared to passive equilibrium circuit, the active balance circuit can effectively improve the balance speed of the high-capacity battery packs, meeting the requirement of balance speed and reducing the energy loss of the battery packs, increasing the service life of the battery packs. The balance circuit can realize modular and control simple. The hardware circuit was built for the project. The experiment results prove the correctness and effectiveness of the scheme.


Depending upon the quantities in which the various essential elements are required, they are generally classified into two groups—the "major" elements (or "macronutrients") and the "minor elements" (or "trace elements or "micronutrients"). It is to be stressed that the use of the terms "major" and "minor" is no reflection on the relative functional importance of these elements. The lack of a minor element can cause symptoms quite as dramatic or often even more so than the lack of a major element.


In this study, the perspective of single parent individuals on single parenthood and within this process the effect of environmental mechanisms on the individual were investigated. The study group of the research consisted of eight people in total, 6 of whom were the students studying at different grades in Turkey, and two of whom were persons who newly graduated. In the research a phenomenological approach was used. The research was carried out with a semi-structured interview technique and the data obtained were analyzed by induction. In accordance with the research metrology and subject, four main themes were determined such as problems caused by the absence of parents, strategies to cope with these problems, adaptation to the social environment and the effect of single parenting on the upbringing. Results obtained from the research show that, single parent individuals have experienced emotional changes in this process, and these emotional changes affect both personality traits of the individual and also their adaptation process to the society at different levels. Keywords: Single-Parenting, Social Change, Socialization, Social Policy.


Besides good yields for the exclusive formation of the trans-isomers (III), this Michael-initiated ring closure reaction also provides the first access to the cis-isomers (IV) of the depicted densely substituted cyclopropanes.


Abstract The Förster Resonance Energy Transfer (FRET) method has wide application in modern science for studying protein–protein interactions and conformational changes. FRET allows to assess molecular interactions by measuring energy transfer between acceptor and donor fluorophores coupled to the molecule(s) of interest. The method demands high precision in experimental design, experimental settings and correct data interpretation. Therefore, we tested several parameters to estimate FRET measurement accuracy in our Nikon wide-field fluorescence FRET system. The experiments were performed in a HEK-293 cell line transfected with DNA constructs expressing Calcium Release-Activated Channel (CRAC) subunits STIM1 and ORAI1 coupled to donor fluorophore Cyan Fluorescent Protein (CFP) and acceptor fluorophore Yellow Fluorescent Protein (YFP), respectively. Exposure time and approach of data analysis varied throughout experiments in order to optimise FRET data quality. Dependence of FRETeff values on measurement quality and donor/acceptor fluorophore ratio in the cells was estimated. We demonstrated that, using the wide-field fluorescence FRET system, minimising the exposure of fluorophores before measurement using neutral density (ND) filters considerably minimises undesirable photo-bleaching of the fluorophores. There was a strong correlation between the CFP/YFP ratio in the cells and the observed FRET level, suggesting that only cells with certain donor/acceptor ratio might be comparable. We also showed impact of FRET measurement quality, defined as accordance of FRET pixels to Gaussian distribution, on FRET artefacts. Knowledge obtained during our experiments may be important for approbating similar wide-field fluorescence FRET systems to study two separate molecule interactions and for understanding the correct setup of the experiments and data interpretation.


We discuss the operational definition of decoherence in various solid state systems. In particular, we review, in the context of spin-based solid state quantum computation, the introduction of $T_1$ and $T_2$ to describe decoherence in a two level system. We provide a perspective on recent experiments involving the manipulation of spin coherence in semiconductors, and discuss specific decoherence and dephasing issues in electron spin-based quantum dot quantum computer architectures.

This article argues that there is a fundamental tension between Joel Feinberg's theory of the nature of rights and his account of what types of beings are potential right-holders. In explaining this tension, I argue that Feinberg actually adopts two competing concepts of rights. Clearly, Feinberg must choose between these two theories, but I suggest that both are attractive and that neither view can be selected as either "correct" or "incorrect" on the grounds of either logical consistency or even straightforward conceptual analysis. In the end, one's preference between these two concepts of rights depends upon competing values, values about which reasonable people can disagree.

The aim of this work was to produce avocado mayonnaise without egg as special foods. This study evaluated avocado (Perseaamericana, Millcvs. Hass and Fuerte) (season 2015). Dry matter, oil content and fatty acid composition were examined and compare it with Maraqiolive oil. Dry matter and oil content of both avocado cultivars were 29.77, 22.00 and 27.85, 20.30%, for Hass and Fuerte, respectively. The results showed that avocado oils were very close to olive oil. Avocado is nutritionally rich in many health related components and a valuable energy source due to their high quality fat content. In conclusion, avocado oil showed higher PUFA/SFA ratio than olive oil. According to total phenol contents and the lipid profile, the stability of avocado oils was similar to that of olive oil. The composition of Hass and Fuerte avocado oils were closed with this of Maraqi olive oil.


The purpose of this research is to assess the dynamics of resilience on single-parent mother who has a child with double-handicap, starting from the initial phase before and after the diagnosis of double-handicap, stress phase because of the escapement of husband and several risk factors that may arise, up to the phase of adaptation and strengthening. This research used the qualitative method by conducting observation and interview to three informants who domiciled in Kendari. The results showed that there are risk factors which become the initial process in the dynamics of resilience on single-parent mother who has a child with double-handicap, such as family disfunction, financial and social problems, parenting stress on the mother and a belief that mystical factor was causing the problems. Those problems raised negative impacts toward the psychological and physical condition. The attempt made to solve the problems was centered on problem focused coping and emotional focus coping by gaining support from the environment and doing daily activities. The processes of raising and strengthening of resilience on single-parent mother who has a child with double-handicap is also supported by protective factors such as hopefulness, learning from experience, the bond between child and mother, and religious belief.


Abstract: Fertilization can cause obvious shifts in nitrate-reducing community composition in agricultural ecosystems; however, little is known about the behaviors and functional characters of isolated nitrate reducers adapted to a specific environment. In this study, 849 nitrate-reducing bacteria were isolated from various fertilization treatments in a long-term paddy field experiment; the isolates were further characterized in functions with both culture-dependent and independent methodologies. The results showed that CK (no fertilizer) treatment had four genera with even relative abundance, whereas the other three treatments had their own predominant genera with Chromobacterium in nitrogen (N) fertilizer, Serratia in NPK (nitrogen, phosphorus, and potassium fertilizer) and Enterobacter in NPKC treatment (NPK plus rice straw). The isolates of Serratia and Enterobacter grew faster and produced significantly more nitrites than those of Chromobacterium and Burkholderia in the normal growth medium, suggesting that the dominant isolates from nutrient-rich environment, such as NPK and NPKC treatments, are better adapted to high nutritional conditions. On the contrary, the strains of Chromobacterium and Burkholderia possessed stronger nitrite production ability in comparison with the isolates of Serratia and Enterobacter in the diluted growth medium, indicating that the selected isolates from CK and N treatments have the capability to develop under nutrient-limiting conditions. Our results indicated that the behaviors and functions of nitrate reducers appears to be important in adapting to their dwelling habitats.

Background
 Efforts to reduce prehospital mortality are limited by the available tools. Transfusion resources are limited, and early identification of coagulopathy is difficult. The future ability to optimize care will be dependent on knowing which resources are best suited for specific treatment, requiring better knowledge of biomarkers to guide decision-making. This study is a preliminary effort to determine how coagulation parameters change over the first 24 hours post-trauma.
 Materials / Methods
 Plasma was collected as part of a prospective observational study on patients (n=59) in the Afghanistan conflict who were administered damage control resuscitation protocols (i.e., hypotensive resuscitation with early blood transfusion targeting a 1:1:1 ratio of red cells, plasma, and platelets). Whole blood coagulation was analyzed on a subset (n=40) at time of arrival (T0) with ROTEM and then again at 6 hours (T6) and 24 hours (T24) post arrival (published in Cohen et al., Transfusion 2019). Plasma aliquots were maintained frozen, thawed at 37 °C for 5 min on day of assaying, centrifuged at 2500-g for 15 min at 4 °C, and visually assessed to exclude hemolysis.
 Fibrinogen (Fg), D-dimer, FV, FVIII, Protein C (PC), antithrombin, prothrombin time, activated partial thromboplastin time, and procoagulant phospholipid time were measured. Thrombograms quantified thrombin generation (TG) lag time, peak, and endogenous thrombin potential. Fibrin polymerization was monitored via turbidimetry after activation with 15 mM CaCl 2. Albumin, free hemoglobin, prothrombin fragment 1.2 (PF1.2), thrombin-antithrombin (TAT), and plasmin-antiplasmin (PAP) were measured by individual assays.
 Time point comparisons were made with repeated measures ANOVA (using a mixed-effects model due to missing values for some patient time points) with Tukey's multiple comparisons tests. Data are presented as means with SD. Pearson correlation coefficients were calculated using a two-tailed p-value output.
 Results
 Based on correlations with previously established ROTEM identification of acute traumatic coagulopathy (ATC), Fg levels from T0 to T6 were used to generate 3 classifications: A) "ATC" for patients with Fg < 200 mg/dL, B) "non-ATC" for patients ≥ 200 mg/dL, and C) "recovering" for Fg < 200 mg/dL at T0 but ≥ 200 mg/dL by T6.
 In all cases, fibrinogen recovered significantly by T24 (Table 1). ROTEM FIBTEM A5 and MCF closely mirrored Fg trends (Table 2). FV and PC were notably deficient in ATC and recovering groups versus non-ATC (Table 1). FVIII declined from initially high levels in all groups over time (Table 1). Longer TG lagtimes were observed in non-ATC (Table 3). In all three groups TAT fell over time, but in non-ATC and recovering, TAT levels fell 70% and 58%, respectively from T0 to T6, while the ATC TAT levels only fell 23% (Table 3). Higher plasma albumin levels were observed in ATC and recovering groups (Table 3).
 Discussion
 Early deficiency of Fg and corresponding heightened prothrombotic responses suggest early administration of Fg would benefit the acute response in traumatic hemorrhage. Early high values of FVIII and TAT indicate endothelial injury and thrombin activation. Over time, the declines in TAT complexes, FVIII, and peak thrombin along with increases in fibrin polymerization time, PT, and aPTT demonstrate a fall of procoagulant thrombin activity, although other factors are likely at work that were not measured here.
 FV and PC were low and consistent throughout, particularly in ATC and recovering groups and may be additional biomarkers for early identification of ATC. Monitoring albumin, TAT, and thrombogram parameters over the first 6 hours could be used as an indicator of patient recovery condition.

In this paper, we investigate the normwise, mixed and componentwise condition
 numbers of the least squares problem min X?Rnxd ||X - B||F, where A ? Rmxn
 is a rank-deficient matrix and B ? Rmxd. The closed formulas or upper bounds
 for these condition numbers are presented, which extend the earlier work for
 the least squares problem with single right-hand side (i.e. B ? b is an
 m-vector) of several authors. Numerical experiments are given to confirm our
 results.


In this paper, we construct a differential spatial multiplexing method that can trade-off spatial diversity for increased transmission rate in differential multi-input multi-output (MIMO) systems. To achieve a desired multiplexing gain while providing simple encoding and decoding, Gram-Schmidt algorithm is used at the transmitter to construct the unitary transmission matrix. In addition, by applying optimum scaling factors to generate transmission matrix, the symbol error rates can be minimized. Because the transmission matrix itself is not the information we are interested in, the equivalent channel parameters for each transmitted information symbols are calculated and the linear signal model for the information symbols is derived. Since that model is exactly the same as that of the coherent spatial multiplexing, all kinds of coherent detection schemes can be directly applied. The advantage of the proposed scheme over the differential space-time block codes (STBC) and the effects of scaling factor are investigated by computer simulation. In high transmission rate regimes, the proposed differential spatial multiplexing method can outperform the differential STBC having the same transmit rate in the signal to noise ratios (SNRs) we are interested in.


This scientific commentary refers to 'Seizure control by decanoic acid through direct AMPA receptor inhibition', by Chang et al. (doi:10.1093/brain/awv325).

Dietary therapies can provide control of seizures in patients with drug-refractory epilepsy. There are several types of dietary therapies, all of which are high in fat, restrict carbohydrates to some extent, and are associated with ketosis. In the classical ketogenic diet introduced into clinical practice in the 1920s, the fat component is provided by long-chain triglycerides (LCTs). Recognizing that medium chain triglycerides (MCTs) are more ketogenic than LCTs, Huttenlocher et al. (1971) created the MCT oil diet, which permits greater amounts of carbohydrate and protein, and therefore allows a more flexible meal plan. The efficacy of the MCT oil ketogenic diet is equivalent to that of the classic LCT ketogenic diet, and the tolerability is also comparable (Neal et al. , 2009). MCTs, which are abundant in coconut and palm kernel oil, have a glycerol backbone and three fatty acid esters with 6 to 12 carbons arranged in a straight chain. The major fatty acids in MCT oil are n -octanoic acid (C8; caprylic acid; 50–80%) and n -decanoic acid (C10; capric acid; 20–50%). Following ingestion, MCTs are rapidly absorbed into the portal circulation to the liver, in contrast to LCTs which are absorbed by chylomicrons in the lymph. It was previously believed that medium chain fatty acids derived from MCTs are immediately oxidized in the liver to form ketone bodies, but it is now known that appreciable amounts appear in the circulation of patients receiving the MCT diet (Sills et al. , 1986 a ). For example, children on the MCT diet had plasma concentrations of decanoic acid in the range of 0.1–0.2 mM. Decanoic acid readily crosses the blood–brain barrier, probably by a combination of diffusion and …


The orientational self-action of a light beam in (1) transparent planar nematic liquid crystal (NLC) subjected to external DC field and (2) planar NLC doped with stilbene dye in the absence of external field has been studied. It is shown that the shapes of the aberrational patterns developed in the far-field diffraction zone are highly asymmetric, unlike the common system of concentric rings. In case (1) the aberrational pattern exhibits complex dynamics of its formation. The shape of the pattern is independent of the polarization of the incident light. In case (2), the divergence of the pattern does depend on the incident-light polarization. In both cases, the light-induced director deformation in the field of the ordinary wave was found. The physical mechanisms of the director reorientation responsible for the asymmetric aberrational patterns are discussed.


This paper reports the experiment conducted at the State School for Primary Education Angelina SalzanoVieira da Cunha, in the municipality of Cachoeira do Sul / RS, which had as main objective to develop, alongwith the students, activities that used farming techniques. Methodologically the work is structured instages. The first step refers to the theoretical foundation, which supported the definition of the conceptsguiding the research. Later, we developed the activities with a group of 7th grade of elementary schoolduring a semester in order to educate, sensitize and prepare students for the issues agroecology, ecologicaland environmental, adapting the experience of integrated practices (related to the use and managementadequate soil) and organic waste. The planting of vegetables, herbs and spices were important to developthe capacity for teamwork, cooperative spirit and responsibility, while emphasized the importance ofhygiene, respect, soil recovery and alternative power. The activities showed good results, since thestudents were motivated and engaged in the practice of management of the garden. Values exceeded theagroecological built school environment because the students brought the knowledge to their homesspreading the idea of sustainable agriculture for their community.


This paper responds to the papers published as a symposium on postmodernism in Sociological Theory (Fall 1991). It argues that postmodernism as a rhetoric and postmodernism as a methodology often diverge among theorists. Further, it contends that theorists' professional locations, including their relative disengagement from undergraduates, may help to account for their attraction to postmodern rhetoric and metatheoretical gesticulations.


We study John, uniform and non-tangentially accessible domains in homogeneous groups of steps 2 and 3. We show that C 1,1 domains in groups of step 2 are non-tangentially accessible and we give an explicit condition which ensures the John property in groups of step 3.


Customer demands for increased data bandwidth require WiFi Access Point (AP) and Customer Promise Equipment (CPE) to support IEEE 802.11n (11n) technology with peak data rates up to 600 Mbps. According to market research reports, almost all new WiFi products have integrated 11n technology, and the forecast for shipments of 11n equipment in 2012 is one billion units. In order to improve the mobile data traffic, 11n will be one of the standard features in mobile phones to address the high data throughput service, such as streaming video and gaming. In this article, we examine 802.11g vs. 802.11n, focusing on the requirements for the power amplifier (PA) or integrated PA front end module (FEM) in 11n designs.


The Lanzo South massif is composed by spinel and plagioclase peridotites: both peridotite types are cut by harzburgite-dunite bands and channels and by gabbroic dikes.
Spinel peridotites are mainly cpx-bearing harburgites and show coarse granular isotropic structures. Their modal compositions are characterized by large olivine contents (Ol up to 93%), which are associated with relatively large Cpx/Opx ratios with respect to those expected for partial melting residua. Peculiar structural features are indicative of: i) early dissolution of pyroxenes and crystallization of new olivine; ii) late interstitial crystallization of new pyroxenes; iii) orthopyroxene replacement on mantle olivine. Their bulk rock chemical compositions show rather low contents in fusible components, relatively high MgO and low SiO2 contents, which do not correspond to those of refractory residua after any kind of partial menting. Structural and mineralogical characteristics indicate that spinel-facies peridotites were early reactively percolated by deep-origin pyroxene(-silica)- undersaturated melts, whereas late percolating melts acquired a pyroxene(-silica)-saturated composition.
Trace element composition of bulk rock and minerals is strongly heterogeneous. In particular, most of clinopyroxenes from spinel peridotites show C1-normalised REE patterns progressively varying from strongly LREE-depleted to sinusoidal L/MREE-enriched. A further peculiar clinopyroxene composition is characterised by strongly humped REE patterns with maximum at EuN and very large MREEN/LREEN and MREEN/HREEN ratios. The strong trace element heterogeneity of clinopyroxenes documents variable chemical exchanges between migrating melts and ambient peridotite during pervasive and reactive porous flow percolation of melt increment formed by £ 5% fractional melting on both spinel- and garnet-facies DM asthenospheric sources.
Plagioclase peridotites are foliated and have porphyroclastic texture. They are composed of a deformed and corroded spinel-facies mantle assemblage and an unstrained interstitial igneous assemblage, which mainly occur as: i) diffuse isolated plagioclase crystals, ii) orthopyroxene replacement on mantle olivine, iii) mm-size iterstitial gabbroic aggregates. Besides, melts either: 1) reacted with and partially replaced mantle clinopyroxenes, forming opx+plg symplectites, and crystallised opx-rich, cpx-free noritic microgranular aggregates, or 2) did not react with mantle clinopyroxenes and crystallised opx-rich, cpx-bearing gabbro-noritic microgranular aggregates. Modal plagioclase proportion is variable, but locally very high (up to 20%). Bulk rock compositions are enriched in silica and fusible components, up to concentrations higher than primordial mantle estimates, and are depleted in MgO. Bulk rock and pyroxenes have incompatible trace element contents significantly higher than those documented in the reactive spinel peridotites.
Petrographic and compositional features indicate that the migrating melts were yet the product of £ 5% fractional melting of spinel-facies DM asthenospheric sources: they attained, most probably, pyroxene-saturation during opensystem migration in the lithospheric mantle. Mineral trace element enrichment was, most probably, assisted by rather large solid-melt partition coefficients during melt-peridotite equilibration. Accordingly, plagioclase peridotites represent refertilized, hybrid rocks, composed by mixtures of mantle peridotites and variable percentages of melt-derived microgabbroic material. Formation of plagioclase peridotites represents the step where the system temperature dropped below liquidus temperature of the percolationg melt: interstitial crystallization clogged the percolations ways and diffuse porous flow percolation collapsed.
Plagioclase peridotites are locally cut by plagioclasebearing tectonite shear zones, where dm-scale bands of plagioclase- free harzburgites and dunites run parallel to the tectonite fabric. These concordant harzburgite-dunite bands are characterised by: i) dissolution of mantle pyroxenes; ii) progressive disappearance of plagioclase and pyroxenes from country plagioclase-bearing tectonites; iii) partial to complete recovering of the tectonite fabrics to coarse granular isotropic fabrics. These replacive rocks document the focused and reactive migration of pyroxene-undersaturated melts along actively deforming ductile shear zones.
The trace element composition of clinopyroxenes from concordant replacive harzburgites shows a large variability, which reflects different evolution stages of the focused melt migration. Some samples have clinopyroxenes showing low trace element contents, sometimes associated with Sr and Eu positive anomalies. Their transient geochemical compositions record the chemical modification experienced by melts during open system migration (i.e. strong melt-peridotite interaction), leading to progressive thermochemical destruction of the plagioclase-bearing assemblage of the country plagioclase peridotite. Other samples have clinopy-roxenes showing trace element concentrations and patterns consistent with equilibration with MORB melts. They represent more advanced stages of migration of MORB-type melts under close system conditions, without significant melt-peridotite interaction. Some concordant harzburgitedunite bands locally contain euhedral clinopyroxene megacrysts showing trace element contents well consistent with equilibration with MORB-type melts.
Meter- to decameter-scale discordant bodies and channels of spinel dunites cut at high angles the spinel foliation of plagioclase peridotites and the concordant harzburgitedunite bands. They locally contain crystals of magmatic clinopyroxene, either isolated or concentrated in irregular pyroxenite bands and gabbroic dikelets, which show fuzzy contacts with the country rock. Dm-wide gabbroic dikes run parallel to the discordant dunite bodies. Clinopyroxenes in both discordant bodies and gabbroic dykes show clear MORB affinity.
Above evidence strongly suggests that MORBs were delivered to shallow levels by focused porous flow in dunite channels and, finally, by intrusion in dikes.
Our studies document a composite scenario of melt diffuse and focused migration in a section of mantle lithosphere, which was progressively exhumed from spinel-facies conditions and exposed at the sea-floor of the Jurassic Ligurian Tethys ocean.
When residing at spinel-facies conditions, pristine spinel peridotites underwent multiple episodes of melt-rock interaction with pyroxene-undersaturated melts formed by fractional melting of a DM asthenospheric source under different pressure conditions.
At shallower levels during progressive exhumation, these reactive spinel peridotites were diffusely percolated by variably pyroxene-saturated incremental melts whose migration collapsed under conductive regime. Percolating melts underwent interstitial fractional crystallization in the mantle lithosphere, forming impregnated and refertilized plagioclase peridotites. The abundance of plagioclase peridotites suggests that large volumes of melts were stored in the lithospheric mantle and never reached shallow crustal levels.
Subsequent evolution was characterised by change of the migration mechanism, from pervasive to focused porous flow and channeling to intrusion, and by variation in the composition of migrating melts, from fractional melt increments to aggregate MORB melts. Early melt batches migrated under open system conditions, they dissolved plagioclase and pyroxenes of the plagioclase peridotite assemblage and their compositions were deeply modified by meltrock interaction. This reactive percolation formed concordant harzburgite-dunite channels. Subsequently, aggregate MORB melts were delivered to shallow levels via focused percolation in dunite channels and via intrusion in dikes.


We present a search for anomalous production of heavy-flavor quark jets in association with a W boson at the Fermilab Tevatron ppbar Collider. This search is conducted through an examination of the exclusive jet spectrum of W+jets final states in which the heavy-flavor quark content has been enhanced by requiring at least one tagged jet in an event. Jets are tagged by the combined use of two algorithms, one based on semileptonic decays of b/c hadrons, and the other on their lifetimes. We compare data in e+jets (164 pb-1) and mu+jets (145 pb-1) channels, collected with the D0 detector at sqrt{s}=1.96 TeV, to expectations from the standard model, and set upper limits on anomalous production of such events.


There is a long debate (going back to Keynes) how to interpret the concept of probability
in economics, in business decisions, in finance. Ivan Belyacz suggested that the Black–Scholes–
Merton analysis of fi nancial derivatives has a contribution to this risk vs. uncertainty
debate. This article tries to interpret this suggestion, from the viewpoint of traded options, real options, Arrow–Debreu model, Heath–Jarrow–Morton model, insurance business. The article suggests making clear distinction and using different naming
● when the frequents approach and the statistics is relevant,
● when we just use consequent relative weights during the no-arbitrage pricing, and
these weight are just interpreted as probabilities,
● when we just lack the necessary information, and there is a basic uncertainty in the business decision making process.

The paper suggests making a sharp distinction between fi nancial derivatives used for market
risk management and credit risk type derivatives (CDO, CDS, etc) in the reregulation process
of the fi nancial markets.


This paper presents the analysis of sectoral energy and exergy utilization of Saudi Arabia by considering the energy and exergy flows for the 12 years between 1990 and 2001. Sectoral energy and exergy efficiencies are obtained for the subsectors and the devices used in each sector. Energy and exergy flow diagrams for Saudi Arabia are also presented, respectively, to illustrate the situation on how energy and exergy efficiencies vary in each sector. The residential sector appears to be the most energy efficient sector, and the industrial sector to be the most exergy efficient. It is believed that the current methodology is useful for analyzing sectoral energy and exergy utilization, which will help Saudi Arabia with energy savings through energy efficiency and/or energy conservation measures. It is also be helpful to establish standards to facilitate application in various sectors and processes for a sustainable energy planning. Copyright © 2004 John Wiley & Sons, Ltd.


The need for Internet application development is now extremely strong. As a result, the internet of Things (IoT) is a significant technology that allows us to create a variety of valuable internet applications. The Internet of Things (IoT) is an excellent and clever method for reducing human effort and providing simple access to physical objects. With the assistance of different current technologies, these gadgets collect valuable data and exchange it with other devices. Home Automation Systems, for example, utilize Wi-Fi or Bluetooth to transmit data between different home gadgets. Many a time's working parents have to worry about their young children left out alone at home but with advancement in technology it is easier to monitor and transmit information within seconds. Either its about monitoring actions of their children inside house or about visitors at the door it can all be monitored easily with the help of Internet of Things. This hardware based implementation aims at child safety and home security by detecting motion and sending photos on telegram bot helping in detection of any anomaly activity in the absence of owner and with the help of photo it provides the user the opportunity to aware the children at home and, they don't need to open the door for the visitor. This paper gives a overview about the Core implementation Details and the deployment of wireless based control system and accessibility inside a home for authorized people only. When visitor motion is detected at Door, Camera module interfaced to ESP32-CAM used to capture images, save it on system and send it as Telegram alert via TCP/IP. Only authorized user can see the images and can even alert the members inside house. This hardware based design helps in monitoring in place of the owner and helps in saving time of seeing long video clips of CCTV in order to check any unusual activity. The entire control system is built using ESP32-CAM microcontroller and tested for actual use in home environment.


DFT Methods
Density functional theory (DFT) is now routinely used for simulating material properties. Many software packages are available, which makes it challenging to know which are the best to use for a specific calculation. Lejaeghere et al. compared the calculated values for the equation of

This device shows no sacrifice of performance over larger, labor-intensive hybrid MIC approaches.<<ETX>>


Two novel approaches are proposed here to achieve a practical RF barcode. Firstly, to achieve a useful number of bits the resonator centre frequencies span three bands: 2.4GHz, 5.25GHz and 5.8GHz. Secondly, resonator width variation is used for fine control of the barcode resonance frequency to within <0.2% accuracy. Bistatic S21 based detection is used based on scattering and absorption to interrogate the barcodes in the field and 5 bit operation is demonstrated successfully in the 5470- 5875 MHz band at 1.5m range. Similarities and differences between the RF barcodes and frequency selective surfaces are explained. The presented design and detection techniques are applicable to other frequencies such as 900MHz and 24GHz.

The emergence of quantization at the nanoscale, the quantum size effect (QSE), allows flexible control of matter and is a rich source of advanced functionalities. A QSE-induced transition into a bulk-insulating phase in semimetallic nanofilms was predicted for bismuth a half-century ago and has regained new interest with regard to its edge states exhibiting nontrivial electronic topology. Here, we reveal an unprecedented mechanism of the transition by angle-resolved photoelectron spectroscopy (ARPES) combined with theoretical calculations. Anomalous evolution and degeneracy of quantized energy levels indicate that increasing contributions of the edge states with decreasing system size deform a quantum confinement potential via many-body electronic correlations. The potential deformation drastically modulates spatial distributions of quantized wave functions, which leads to acceleration of the transition even beyond the original QSE picture. This discovery is generalized to a novel size effect that embodies nanoscale enhancement of correlations centering on metallic edge states---a key feature of recent topological materials.


In Iceland, efforts to drill High Temperature and High Pressure wells have proved very successful in recent years. In 2001, only two HT wells were completed, whereas 27 wells were completed, in 2007 and a similar amount will be drilled in 2008. High accuracy and reliability of data from deep high temperature wells has been the main driving factor for Iceland GeoSurvey to implement the latest electronic instruments (Dewar flask tools), from Kuster Co., California, the socalled K10 (Strain tool). As a consequence the classical mechanical Amarada and Kuster tools were retired to back-up tools. Though the mechanical tool are sturdier tools the data quality and resolution is not up to date with respect to client requests. An introduction of new drilling technology, mainly for environmental reasons and in order to intersect fractures perpendicularly, meant a shift from drilling near vertical wells to deviating around 90% of the wells. As a direct result of this shift Iceland GeoSurvey is the logging contractor in the world logging most intensively in deviated wells. In logging, the first concern is to obtain data from the entire length of any given well i.e. getting successfully down the well and retrieving the tool. A few problems have occurred during the past four years: extremely corrosive geothermal fluid (Reykjanes area) causing brittle failure on the slick-line; highly inclined wells (~40-60° from vertical), means that the tool might stop on its way downhole; extensive wear on Dewar flask as the tool rubs against wall-rock constantly while logging, which calls for centralizers and further; lack of experienced personnel (Iceland GeoSurvey logging department has expanded its personnel over 3 years from 6 to 22 people); extreme high well head pressures (128 bar recorded), which can strain the well head to the breaking point, also extreme high downhole temperatures (385°C recorded) calls for vigilance, due to limited downhole lifetime of the electronics. Iceland GeoSurvey has solved many of afore mentioned problems with great success, bearing in mind that solutions need to be revised regularly, as new obstacles occur. Though the K10 tools are generally more fragile than the older sturdier mechanical tools experience has shown that denser and more reliable data sets are obtained spending less time and money. High resolution and quality of datasets also give greater knowledge and improves interpretation and modelling. Planning, safety and good communicating between clients and contractor play very important roles in ensuring good quality of the end-product and all are parts of the success criteria.
