DESCRIPTION A 79yearold man with medical history of coronary artery disease and atrial fibrillation treated with anticoagulant drugs was admitted to the emergency department with an episode of massive gastrointestinal haemorrhage presenting as melaena. On examination, he was haemodynamically unstable. The abdomen was painful on the upper quadrants and rectal examination confirmed melaena. Analysis revealed a haemoglobin level of 50 g/L. The patient was stabilised with supportive measures and twounit red blood cells transfusions. The posttransfusion haemoglobin level was 90 g/L. Upper endoscopy revealed submucosal ulcerated tumour arising from the antrum. The CT scan revealed a well- encapsulated and fat- attenuated lesion (−90 Hounsfield units) in the gastric antrum, measuring 6.2×3.3 cm (figure 1A and video 1). Endoscopic ultrasound confirmed the presence of submucosal hyperechoic lesion measuring 9×4 cm without evidence of perigastric lymph node enlargement (figure 1B). Biopsy was inconclusive. The patient underwent gastrotomy with tumour enucleation (figure 2). Postoperative recovery was uneventful. There was no bleeding recurrence during followup. Histological examination confirmed the diagnosis of submucosal lipoma with 9.5×4.8×2.5 cm and ulceration. Lipomas account for 1%–3% of all gastric tumours. They represent 5% of all gastrointestinal tract lipomas. Lipomas are mainly found in women. They are most prevalent between the fifth and seventh decades of life. Gastric lipomas are usually solitary. In 75% of cases, they are found in the antrum but can arise from every part of the stomach. 5 Small lipomas (<2 cm) are usually asymptomatic and can be incidentally identified during a radiological or endoscopic examination. Larger ones (>4 cm) can manifest clinically with gastric outlet obstruction, gastroduodenal intussusception or upper gastrointestinal bleeding due to mucosal erosion. 2 4 6 Upper gastrointestinal endoscopy usually reveals a submucosal mass with three signs that help establishing the diagnosis: pillow sign, tenting sign and a naked fat sign. Most lipomas are submucosal (95%), which means regular mucosa biopsies are inconclusive. 4 6 Endoscopic ultrasound reveals a hyperechoic, homogeneous and wellcircumscribed submucosal lesion. 7 CT scan reveals a wellcircumscribed homogeneous submucosal mass with anattenuationvalueof−70 to−120Hounsfield units which is pathognomonic of gastric lipomas. 9 Simple excision of the lesion is usually adequate since recurrence rates are low. Asymptomatic and indolent gastric lipomas can be managed without intervention. 10 Large (>4 cm) and symptomatic tumours were traditionally treated with laparoscopic or open surgery such as enucleation or even partial gastrectomy. 10 11 Nowadays, endoscopic submucosal dissection (ESD) has become a technically feasible and safe alternative to conventional surgery for removal of large lipomas. Nevertheless, a case of obstructive symptoms has recently been reported after a large lipoma (8×6 cm) Figure 1 (A) CT scan revealed a wellencapsulated and fatattenuated lesion in the gastric antrum.

Modern clean energy electric intelligent driverless cars are still on the road to commercial operation. Urban rail transit subway modern green energy electric intelligent unmanned driving technology has been maturely applied in many subway lines at home and abroad. People who have seen various sci-fi movies and have repeatedly broken through the expectations of real-world artificial intelligence technology can't help but wonder: Is there a subway that can be opened without a driver, can it be smarter and more "smart"? Is it like "Transformers", really become "robots", have brains, will make their own decisions? The imaginary dream has gradually become a reality! When people are still amazed by the modern clean energy, intelligent and unmanned subway, and many routes around the world, the line of the unmanned green energy electrical intelligent system independently developed by the trains of the domestic rail transit subway line has arrived.!


Inheritance of red purple vs. tan plant (leaf sheath) colour was studied in six intervarietal crosses of sorghum (Sorghum bicolor (L.) Moench.), 'LSR 1 × GS 3541', 'RCR 408 × CS 3541', '148 × LSR 1' 'GS 3541 × IS 84', 'IS 3691 × GS 3541 and 'IS 84 × 148'. Fa segregation showed a 3:1 ratio for red purple; tan colour, indicating operation of single gene in the inheritance of this character in all the six cross combinations. The monogenic recessive tan plant colour was observed.


Electric solid propellants are an interesting potential option for propulsion because they are ignited by an applied electric current. The electric nature of these materials leads to the capability for use in pulsed electric propulsion devices. In this work, the ablation process of an electric solid propellant during pulsed microthruster operation is investigated using a triple Langmuir probe, thrust stand and high speed video camera. Results include quantitative time-of-flight, ablation mass per pulse and impulse-per-pulse measurements. Additionally, qualitative images from the high speed video are temporally correlated to these measurements. Analyses indicate 45±11% of the ablated mass per pulse is expelled at negligible speeds relative to the effective plume exhaust velocity (1500 m/s). Further, this occurs on a time scale that is three times longer than the 0.5 ms primary discharge. This late-time ablation has been identified in other pulsed microthrusters with traditional Teflon propellant, and the results presented here indicate that electric solid propellant exhibits similar behavior.


【The fauna associated with mussel (Mytilus galloprovincialis) beds and vertical distribution of macrobenthos were studied on the Goijeong rocky shore in Jinhae Bay, Korea. Sampling was conducted seasonally using a quadrate from January to October, 1998. In the first experiment, to reveal the community structure of macrobenthos in mussel bed, a total of 62 species $(10,690ind./m^2,\;3,802.1\;g/m^2)$ were identified, which included polychaetes $(32\;spp.,\;52.6\%),$ molluscs (16 spp.), crustaceans (10 spp.), and others. The density-dominant species were Pseudopolydora antennata, Nereis heterocirrata, Littorina brevicula and Balanus kondakovi. And the density of associated fauna was correlated with that of mussel (r=0.951, p=0.049). In the second experiment, to reveal the vertical distribution of macrobenthos on the rocky shore, ANOVA showed highly significant differences between the density of top 5 dominant species (Chthamalus challengeri, Littorina brevicula, Balanus kondakovi, Septifer virgatus and Granulilittorina exigua) and tidal levels (P=0.000). Vertical distribution of macrobnethos was characterized by Ghthamalus belt and Balanus-Septifer belt in the mussel bed.】


Nobody would question the trade-off between product quality and price. However, negotiations between buyers and sellers tend to circle primarily around pricing, because it is a simple quantitative figure compared to product quality, which is much harder to comprehend. Every seller of good quality products does fear the race to the bottom, when uninformed buyers ask for discounts. To alleviate this situation, findings from behavioral economics, applied to basic market mechanisms, show a bias towards trade with higher quality products. The trade of money for goods is transferred into a choice for gain or for loss in ways considered a novel concept. Risk aversion and risk seeking of buyers can counterbalance market downturns, constituting a barrier against crooked sellers taking over the marketplace with low quality products. A basic model demonstrates that information symmetry is not necessarily a prerequisite to maintain a healthy market.


Roe deer Capreolus capreolus food and feeding habitat selection was studied by snow tracking on transects along an altitudinal gradient in Flatdal, the county of Telemark, south-central Norway, during winter 1979/80. The main food was bilberry Vaccinium myrtillus (36.8%), rowan Sorbus aucuparia (24.4%) and arboreal lichens Alectoria sarmentosa, Bryonia spp., Hypogymnia physodes, Usnea spp. (17.4%), which were also the only preferred food plants. The amount of food removed from the field layer was stable through the winter. Roe deer used the lower part of the study area most heavily. At lower altitudes, older mature stands and edges between medium-aged stands and clear-cuts/plantations were preferred, pole-sized stands and edges between older mature stands and clear-cuts/plantations were used as expected from their availabilities, whereas medium-aged stands, clear-cuts and young plantations were avoided. That snow depth was an important factor determining habitat use by roe deer was evident in three ways: 1) use of areas at higher elevations decreased as winter progressed, 2) use of mature forest stands increased from early to late winter relative to open habitats, and 3) use of mature forest stands was more extensive at higher than at lower elevations compared to open habitats.

In the "standard" adiabatic approximation, this work is the first time to report the isotope effect in the electron impact dissociation of H2^+(1sσg) and D2^+(1sσg). The various dissociative cross sections of the Born asymptote calculated according to the Bethe theory due to Inokuti et al are given for studying the isotope effect. There is almost no isotope effect in the electron impact ionization and a 2% of isotope effects in the electron impact dissociation at incident energies≧200 eV. The good agreement behveen theory and experiment for the isotope effect in the total ion production is found. This work also points out that accurate experimental data of the rotational-vibrational(R-V) state distributions of H2^+(1sσg)and D2^+(1sσg) with an error less than 5% are required to study the small isotope effects reported here. The isotope effect of experimental measurements in the electron impact dissociation of H2 and D2 is identified to be much larger than the theoretical values deduced from the study of total inelastic scattering at high incident energies (>500 eV). The large isotope effects in the electron impact dissociation is argued mainly due to the contribution from predissociation via the "superexcited" state of molecules. The nonadiabatic approach to understanding the coupling between electronic and nuclear motions based on the multichannel quantum defect theory (MQDT) is outlined to discuss the large isotope effects.


The current teaching mode of Furniture Design and the existing problems with it are analyzed,and the attention to the pertinence of the course system in teaching and the stress on the adaptability of basic course teaching and practicability,rationality and continuality of professional course teaching are pointed out.


In a pot experiment,the clonal ramets of Cynodon dactylon,the stolon herbaceous plant,were treated with heterogeneous lighting. Shade stress was carried out on the distal ramets( younger ramets) to three different degrees,and the stolons between the proximal ramets and distal ramets of each pair were treated in an intact or severed manner. The results show that in moderate shade stress,the stolons severed significantly decreased the biomass and net photosynthetic rate( Pn) of distal ramets,and that in serious shade stress,the stolons severed significantly reduced the number of ramets,the number of leaves,biomass,net photosynthetic rate( Pn),the maximal quantm yield of the photosystemⅡ( Fv / Fm)and the effective quantum yield of PSⅡ( ФPSⅡ) of the distal ramets,and that clonal integration alleviated the negative effects of shade stress on the growth of distal ramets. In moderate shade stress,the stolons being intact significantly increased the net photosynthetic rate( Pn) of proximal ramets. In the serious shade stress,the stolons being intact effectively improved the maximal quantm yield of the photosystem Ⅱ( Fv / Fm) and the effective quantum yield of PS Ⅱ( ФPSⅡ) of the proximal ramets. Thus,clonal integration drove the photosynthetic rate of the unstressed proximal ramets to compensatory increase. In contrast to the treatment of the stolons severed,clonal integration would significantly reduce the biomass of the unstressed ramets,but result in no significant change of the whole clonal fragments when the distal ramets were treated with serious shade stress. Therefore,when the distal ramets suffer from serious shade stress,Cynodon dactylon,the stolon herbaceous plant,may take a risk-spreading strategy to reduce the death of genets,which is of vital importance to maintain the fitness of the genets of clonal plants in heterogeneous environments.


In order to realize functions of automatic monitoring, alarming and extinguishment on fire in crude oil storage tank, the paper came up with a fire detection model with multisensor, including selective module with fire feature combination, supervised training module and fire detection module. By regarding PNN as a classifier to carry out tests on effectiveness of the model, the conclusions that the model can reduce the influence of fire parameters' fluctuation on detection results was drew. Moreover, an excellent fault-tolerant ability was possessed at the same time. Through some confirmatory experiments, The phenomenon was reached that two kinds of parameters in adoptive four parameters have no normal fire signal, but the model still can greatly distinguish from correct fire state.


Disrupt/Displace was both a Venice Architectural Biennale Session and a "Report from the Front" on the Dakota Access Pipeline: simultaneously a critique, a performance, and a proposal presented in four parts: PART 1: Searching for the Front (Iowa), PART 2: Constructing the Front (Iowa), PART 3: Reporting the Front (Venice), PART 4: Assessing the Front (Venice). Alejandro Aravena's curatorial statement for the 2016 Venice Architecture Biennale, "Reporting from the Front," provided context for Disrupt/Displace, which emerged from doubts about the possibility of political resistance in the practice of architecture.1 As a project Disrupt/Displace serves as a tool for understanding both architecture's complicity in perpetuating spatial forms of political oppression and as a method that enables architects to resist disciplinary nihilism and defensiveness when confronted with intractable political issues.


The present invention discloses a method for synchronizing a clock signal which designs a ring oscillator with a stable fractal structure. The method for synchronizing a clock signal comprises the following steps of: receiving a voltage source from a first chip generating a first clock signal and a second chip generating a second clock signal; oscillating the first clock signal and the second clock signal in a clock line located between the first chip and the second chip; and outputting the first clock signal and the second clock signal as the clock signal having the same frequency and the same phase. The clock line connects three ends of the first chip and the second chip having the same fractal structure.


Abstract:
 By forced vomiting of stomach contents, we examined the diet of Lithobates catesbeianus inhabiting the city region of Kyoto, central Japan. Among various animal taxa consumed, crustaceans, including Asellota and Oniscoidea in juveniles and introduced American crayfish Procambarus clarkii and native crab Potamon dehaani in adults, occupied the largest proportion in number. In volume, the crayfish and crab also comprised the larger part, and the rest was composed mainly of beetles, bugs, and centipedes. Food habits of L. catesbeianus from Kyoto are characterized by the following points: (1) the frog tends to take a smaller number of larger prey as its body size increases; (2) aquatic prey animals, especially crustaceans, seem to be more important than terrestrial ones; (3) feeding intensity seems to be constant throughout the active seasons, including the breeding season; and (4) vertebrates comprise only very small proportion of the diet, despite their apparent availability, strongly contrasting to previous studies in other localities. Effects of predation on native animals seem to be not very large at present.


Abstract This article is an attempt to draw attention to the differentiation used to conserve endangered and protected species of flora in an area that is administered by the management board of the State Forests. I also draw attention to areas of insufficient knowledge of this subject-matter. A detailed inventory of endangered and protected species of flora for the purpose of planning in forestry would be very useful in light of laws related to nature conservation and the problem of preserving biological diversity. Research in the forest administration region of Sokołowice indicates that almost 2/3 (65.16%) of all sites harbouring endangered and protected species of flora are new (previously undocumented), despite the existence of numerous protected areas – this fact indicates that there are great research possibilities in this field. The main conclusion from this research confirms that multifunctional forestry in Poland will provide the greatest opportunity to preserve the widespread and numerous sites holding endangered and protected species of flora in economically important forests.


A number of new developments are claimed in the name of "vertical city", yet few represents an important characteristic of a city, which is the ability to constantly transform. Based on the analysis of several successful and unsuccessful precedents of building complexes, this paper aims to propose a novel approach of vertical city featuring constant vertical urban transformation by applying the state-of-the-art construction technologies. Meanwhile, this vertical city approach has the ability to integrate five basic elements of a city: vertical and horizontal circulation systems as its paths, a flexible building envelope as its edges, variable mix-used functional blocks as its districts, sky bridges and roof gardens as its nodes, and the complex itself as a landmark. More importantly, it can change its size, form and function with the help of construction automation technologies and open building principles, and responsively evolve in accordance with social, economic, and environmental shifts in a self-sufficient manner, meanwhile avoiding the risk of being homogeneous with surrounding buildings. Eventually, the complex will perform as a series of interconnected components which act together to form a living organism that performs various functions and purposes such as office, residential, commercial, school, hospital, police station, and infrastructure


In Iceland concerns have been raised about the unrealistic body ideals young women are presented with and their impact on self-esteem and body image. Quantitative research confirms these concerns and indeed it seems that women are unhappy with their body weight throughout their life course. At the same time, research into the cultural and social discourses that underpin and shape young women's ideas about the relation between body weight and femininity, has been scant. This article adopts a feminist poststructuralist framework to explore young women's (18-24 years old) ideas about the importance of body weight when dating. This is based on research that used a story completion methodology to explore the sociocultural ideas participants draw on when making sense of the topic. In the research, participants were randomly presented with either of two different story stems and asked to complete the story. In the first story stem a fictional female character is on her way to a date and notices when she looks in the mirror that she has lost weight. The second story stem is identical apart from the female character noticing that she has gained weight. The participants were approached on social media where they were provided with a link that directed them to the task on SurveyMonkey. In total, 81 participants provided stories. Out of these, 73 stories could be used in this research. When participants had completed their stories they were asked two further questions about the story character and then asked to answer some demographic questions. The stories were analysed thematically. The analysis resulted in 4 themes: (1) the body should not disappoint (him), (2) looks facilitate/are an obstacle to good self-esteem, (3) the body and the self constitute tasks that must be worked on, (4) resistance to body ideals consists in accepting your body. It was interesting that most of the participants seemed to assume that the story character was heterosexual and was on her way to meet a man. In the stories collected we saw clear signs of postfeminist discourses where women are presented as the entrepreneurs of their lives, free to make choices that shape their lives. In many of the stories it was assumed that it was the young woman's responsibility to ensure that her body was of value so that she would not disappoint possible lovers and herself. It was also clear that slim bodies were deemed to be of more value than fat bodies. What came across clearly was that it was the young woman's responsibility to work on her body and mind-set so that she could be "the best version of herself". In the stories where the fictional character had gained weight, we detected much body shame and even repulsion towards the fat body. The thought of gaining weight was described as filling the character with much dread and anxiety. When the character had lost weight, she was described as excited about the date but also filled with dread because she anticipated that no matter how much weight she lost it would never be enough. A common description of the story character was that she was a typical anxious and insecure girl who needed to sort herself out; that is, the causes of her problems rested in herself. In contrast, some of the stories seemed to draw on feminist discourses criticising societal pressures on young women to be slim. This resistance was particularly apparent when the character had gained weight. The stories outlined how the story character decided to ignore the slim ideal so that she could accept and love her body. The paper provides an insight into the complex relationship young women have with often hostile socio-cultural ideas about the young female body and the constant surveillance and work those ideas demand from them. We call for a greater interrogation of cultural ideals that either blame young women or their peer group for their anxious relationships to their bodies. We also conclude that the storycompletion method is useful for collecting data. Despite some of the stories seemingly being written in jest they overall presented a rich and nuanced scenario. As such they provide clear insights into the cultural and social discourses participants have access to when writing their stories.


Abstract: Arab countries have been faced with a large scale Middle Eastern upheaval, which has attracted the attention of all the Middle Eastern countries and international community. The current situation is primarily related to the important location of the Middle East. Nearly all the Arab countries are involved in the upheaval. Omnifarious appeals are claimed by the people, including political, economic and social aspects. The problems have been accumulating for years, and the Middle East upheaval in 2011 was an overall outburst of people's dissatisfaction. The cost of the unrest is high despite the social progress it may promote. At present, a fragile peace is realized in Syria though the prospect of future development is unclear. Since the outbreak of the Middle East upheaval, China has adopted a principle of "non-intervention in other's internal affairs" and "mediating for peace while promoting talks" policy, which is appropriate and proactive. China should adhere to this practice in the future despite the voices of opposition and temporary misunderstanding.


Abstract : The recent inclusion of stability operations as a core mission set (DODI 3000.05 and JP 3-07) for the U.S. military has highlighted the efforts operational commanders must consider when planning for the post-combat phase of a conflict in an underdeveloped state. The desired end-state of most stability operations includes a sustainable economy within the underdeveloped state. Operational commanders must plan to assist in setting the conditions necessary to achieve a sustainable economy. Sustainment in support of combat forces and infrastructure development tasks can be leveraged to help achieve the conditions necessary for a sustainable economy. The operational commander's lines of effort must include short-term and long-term procurement strategies, such as employment generation and contract incentives, to aid in the establishment of a sustainable economy. Joint doctrine also must incorporate these new strategies to institutionalize military contributions in achieving a sustainable economy in support of stability operations.

It is to be noted that Article 1 is introduced by the phrase, "as the term is used in this Convention." Article 1 does not embody a definition, therefore. Instead, it merely explains the use of a certain term which is frequently employed in later articles. I t is designed to block out those phases of the subject with which this Convention is intended to deal. In the literature of diplomacy and international law the term " t r ea ty" is employed in both a general and a restricted sense. In the former sense, it is well defined by Renault as " tout accord intervenu entre deux ou plusieurs 6tats, quelque maniere qu'il soit constate" (traits, convention, protocol, declaration commune, echange des declarations unilat^rales)." Introduction a VEtude du Droit International (1869), pp. 33-34. See also 1 Anzilotti, Cours de Droit International (Gidel trans., 1929), p. 353, and Chailley, La Nature Juridique des Traitis Internationaux (1932), p. 6. In a restricted sense the term " t r ea ty" is sometimes employed to designate a particular type of instrument which, by reason of its importance or dignity, the nature of the subject-matter with which it deals, or the procedure by which it is concluded, is distinguished from other international agreements or instruments designated by other names, such as conventions, protocols, arrangements, etc. However, this distinction is not always observed. (See the Comment on Article 4.) J. B. Moore ("Treaties and Executive Agreements," 20 Political Science Quarterly, 1905, p. 388), remarks that while in diplomatic literature the terms treaty, convention, and protocol are all applied more or less indiscriminately to international agreements—in the jurisprudence of the United States, the term treaty is properly to be limited, although the federal statutes and courts do not always so confine it, to agreements approved by the Senate. Thus American courts have held that postal conventions concluded by the PostmasterGeneral under authority of an Act of Congress and approved by the President without the advice and consent of the Senate are not "treaties" in the sense of the constitutional and municipal law of the United States.

The effort described in this report involved a joint industry-university program between the Signal Research Center, Inc., and the University of Illinois, designed to advance the state of knowledge of zeolite catalyst characterization technology for application to zeolite catalysts useful in coal liquefaction related processes. The program involved the application of new and improved high resolution solid state nuclear magnetic resonance (NRM) techniques to the characterization of zeolite catalysts and other related microporous materials. The NMR experiments were performed in the state-of-the-art NMR laboratory at the University of Illinois. In this report the first comprehensive investigation of /sup 17/O NMR of A and Y zeolites by means of static, MASS and VASS (variable angle sample spinning) NMR techniques is presented. The determination of the /sup 17/O isotropic chemical shifts, nuclear quadrupole coupling constants and electric field gradient tensor asymmetry parameters provides valuable supplementary information on zeolite structure. As an extension of the /sup 17/O NMR investigation of zeolites, results for gallosilicates and for several aluminophosphate materials have also been obtained. The work presented in this study demonstrates the ability of using /sup 17/O NMR to observe chemical changes in the oxygen environment of zeolites. This has important implications for themore » study of zeolite based catalysts. Chemical modifications of catalysts, such as framework substitutions or ion exchange which are commonly used to modify zeolite catalyst activity can be directly studied for their effect on the oxygen rich surface of the zeolite. It is also possible that this technique could be used to directly probe the interactions between the zeolite surface and reactant molecules. 29 refs., 14 figs., 7 tabs.« less


In this paper I explore the relationship between law, history, and reconciliation in the Canadian context. I argue that linear, teleological forms of history are employed by courts to continually reiterate the myth of a legitimate assertion of colonial sovereignty. By doing so, any potential for political transformation that lies in the objective of reconciliation is stunted; political challenges brought in the form of aboriginal rights claims are folded back into the existing political, economic, and juridical structures of the nation-state. I conclude with an examination of how spatializing history in a nonlinear, nonteleological way could open up possibilities for political change and transformation.


The complexity of the disaster risk landscape and the exposure of large human populations to prolonged and potentially traumatizing events were on full display during Hurricane Harvey. During the 5 days of Hurricane Harvey, more than 33 trillion gallons of rain fell on Texas and Louisiana and set a continental US record for rainfall at 51.88 in (131.78 cm). Among 13 million persons directly affected by the storm, more than 22 000 were rescued from floodwaters, an estimated 32 000 displaced survivors were temporarily housed in shelters, and at least 450 000 will apply for Federal Emergency Management Agency (FEMA) disaster assistance.1 More than 100 000 homes were damaged and only 17% of the affected residents had flood insurance. Damage and recovery estimates are projected to exceed those incurred during Hurricane Katrina ($114.5 billion paid on an estimated $160 billion in damages). The usually circumspect National Weather Service tweeted, "This event is unprecedented & all impacts are unknown & beyond anything experienced." During Hurricane Harvey, Texas and Louisiana residents experienced the full complement of hurricane hazards: cyclonic winds, tornadoes, storm surge along a concave coastline, deluging rains, and inland flooding.2


This report presents the theories, the numerical methods, and the computer program for the analysis of the collapsing bow of a striking ship on the assumption that the struck ship is stationary and rigid. This assumption simplifies analysis of the interactions between the struck and the striking ships and is valid for the struck ship with a resistance type of protection barrier. The ice breaker POLAR STAR has been used as an example for testing the computer program for an assumed collision with a collision angle of 60 degrees. The results indicate that the collapse load of the ice breaker for a 60-degree striking angle is about 35 percent greater than that for the perpendicular collision. While the results from this study are useful, further effort is necessary to develop this methodology into a practical design tool. A following study will combine the mathematical models for the struck ship and the model for the collapsing bow with the external mechanics of ship collision. Completion of this study will enable the calculation of the coupling effects between the ship motions and structural damage of the two ships involved in collision.

The invasion of natural ecosystems by exotic species is considered one of the major processes threatening global
biodiversity (Species Survival Commission 2000). Disruptions to ecosystem function and changes to patterns of native species richness and abundance are common forms of degradation attributable to exotic or pest species invasions (Sax & Brown 2000; Species Survival Commission 2000). To date, all continents have been negatively affected by the introduction of exotic species. However, islands and other isolated habitats have been significantly more susceptible to biodiversity loss (Mack et al. 2000; Sax & Brown 2000). This susceptibility is attributed to higher levels of endemism in these isolated regions (Species Survival Commission 2000).


Abstract An aminosilylated substrate was treated with aziridine to prepare hyperbranched polymers on solid supports. It is observed that the primary amine on the substrate is able to initiate the ring-opening polymerization of aziridine. Measuring the thickness of the film and absolute density of the primary amine functionality shows that a very highly branched poly(ethyleneimine) is formed since the primary amine functional group on the very top surface increased dramatically from 3.6 amines/nm2 to 66–78 amines/nm2. Atomic force microcopy shows that the polymerization is rather regular laterally and that the morphology of surface has not changed significantly after the polymerization.


Ultrastructural changes induced by water stress were investigated in broad bean (Vicia faba) and barley (Hordeum vulgare) root cells by electron microscopy. Stress grain formation and subsequent heterophagy as previously observed in slowly-desiccated corn root cells was also observed in the cortex cells of both desiccated plants.


In order to investigate the relationship between physical property and foaming property of slag with low FeO content during after desiliconization,the viscosity,surface tension,and foaming property of [CaO-SiO 2-FeO(5-15%)-Al 2O 3(10%)] quaternary system,with a basicity within the range of 0.4~1.0,were determine. The result shows that the surface tension of slag is high.The foaming index is mainly affected by slag viscosity and inversely proportional to the content of FeO.When the content of FeO is decreased to about 5%,the influence of basicity on foaming index is more stronger than ever.


1. Changes in blood sugar levels after giving carbohydrates have been used to assess carbohydrate utilization in pre-ruminant calves aged between 10 and 50 days. 2. Glucose, galactose and lactose were readily utilized by all calves; the utilization of glucose and galactose increased with age, whereas that of lactose remained constant. 3. Maltose and fructose utilization was low in young calves and increased slightly with age. 4. Sucrose and starch were not utilized. 5. Studies with three older pre-ruminant calves (aged 53, 88 and 106 days) in which the carbohydrates were infused into the proximal duodenum showed that glucose, galactose, lactose and xylose all caused marked increases in the level of blood reducing sugar, whereas fructose and sucrose caused no increase, and maltose was intermediate. Xylose and galactose caused very little change in the blood glucose concentration. 6. It appeared that preferential uptake occurred of glucose from a glucose-galactose mixture. 7. A non-linear relationship was found between the concentration of glucose or galactose infused and the increase in the level of blood reducing sugar.


3D Object detection in 3D views is important and fundamental in the computer vision field.Its core issues include coping with the problems of partial occlusion,intra-class variance,cluttered background and multiple views.Most recently,with the development of part-based model,the occlusion and intra-class variance problems have been partly solved.Therefore,researchers have focused their attention mainly on multi-view problem.This paper gives detailed analysis of the 3D object detection problem with emphasis on the recent works related to this problem.At last,we summarize the algorithms introduced and give their comparisons.

Two key air pollutants that affect asthma are ozone and particle pollution. Studies show a direct relationship between the number of deaths and hospitalizations for asthma and increases of particulate matter in the air, including dust, soot, fly ash, diesel exhaust particles, smoke, and sulfate aerosols. Cars are found to be a primary contributor to this problem. However, patient awareness of the link is limited. This chapter begins with a general discussion of vehicular dependency or 'car culture', and then focuses on the discussion of the effects of air pollution on asthma in the Netherlands. I argue that international organizations and patient organizations have not tended to put pressure on air-control, pollution-control or environmental standards agencies, or the actual polluters. While changes in air quality and the release of greenhouse gases are tied to practices like the massive corporate support for the ongoing use of motor vehicles and the increased prominence of 'car culture' globally, patient organizations seem more focused on treating the symptoms rather than addressing the ultimate causes of the disease. Consequently, I argue that to fully address the issue of asthma the international health organizations as well as national health ministries, patient organizations, and the general public must recognize the direct link between vehicular dependency and asthma. The chapter concludes with a recommendation for raising environmental health awareness by explicitly linking the vehicular dependency to the state of poor respiratory health. Strategic policy in the Netherlands then should explicitly link the present pattern of auto mobility to public health.

The authors have developed a software robot called a softbot that incorporates the artificial intelligence techniques of planning and machine learning. This flexible, extensible agent handles information requests by letting users specify, what must be accomplished; the system then determines how to accomplish it. >


Digital Marketing have revolutionized the way companies communicate and interact with their publics, in particularly in the Fashion Business. The use of digital communication on a daily is increasingly intense, which leads companies to work the digital business strategy around the objectives, as well as incorporating digital methods into the objectives. According to Hamel, "The advantage of the competitiveness comes from a technological introduction and the constant adaptation along the time to the technological evolution inserted in the strategy of the organization." This research is a qualitative analysis to understand what are the digital factors that contribute to sustainable competitive advantages of organizations which can support strategic and future actions.


Describes a method of analysis for detecting and minimizing memory latency using a directed data dependency graph produced from a compiler. These results are applicable to the development of methods for the optimal generation of instruction threads to be executed on a multi-threaded, data-driven architecture. The resulting runtime reductions are accomplished by minimizing memory access times by individual processing elements. Additionally, these analysis methods can be used to predict measures of achievable parallelism for a given program graph which can be exploited by a reconfigurable, multi-threaded architecture.


The wall tension of a rough wall is considered within a semi-infinite planar Ising model. Using Monte Carlo simulation techniques, we have studied the influence of the geometry of a rough surface on the wall tension. Different geometries are examined in detail, ranging from elementary deformation of the flat surface, including pores, to more realistic substrates generated randomly with a given roughness. We give evidence that complex geometries lead to wall tensions that are bounded by those associated with two simple well-characterized substrates, protrusion and pits.


The backwardness of Russia when compared to the countries of Western Europe was apparent at turn of the 17th and 18th centuries, when, it is generally considered, Russian economic growth began. From that time on, overcoming this backwardness, reducing the gap between Russia and the more developed countries of Europe and the rest of the world, became the principal goal of Russian economic development and the principal task of Russian governments. This task, which may be described as that of "modernization in order to catch up", was first articulated by Peter the Great (1683-1725) whose celebrated economic and technological changes were achieved thanks to a policy of borrowing from the West.


INTRODUCTION As the nanotechnology has progressed rapidly, displacement measurement methods with picometer resolution will be required in the near future [1]. Currently, commercial laser interferometers are widely used as length standards in industries. However, the interferometer suffers from cyclic errors of several nanometers due to an imperfection of the fringe interpolation [2]. Therefore, it is difficult to determine an arbitrary displacement with accuracy of nanometer or better using the interferometer. On the other hand, a phase modulation homodyne interferometer (PMHI) [3] can determine an optical path difference (OPD) with picometer resolution using the lock-in detection and the null method, when the OPD equals a product of an integer and the wavelength.


Electronic patient portals, such as MyChart by Epic, allow patients to view their medical records, request medication refills, and communicate with their health care providers. Factors associated with portal use include being younger, female, White, having private insurance, and having chronic illness.1The Hospital for Special Surgery (HSS) rheumatology clinic serves primarily patients with public insurance (Medicaid, which insures low-income adults, and Medicare, which insures adults >65 years old and those with eligible chronic illness/disability). These patients may be at increased risk for poor health outcomes due to clinical and socioeconomic factors and they are less likely to use MyChart than patients seen in HSS private practices. Increased MyChart use may benefit this high-risk group and improve health equity.This study aims to identify characteristics associated with MyChart activation and reasons for its underutilization among patients seen in the HSS rheumatology clinic.We identified all patients aged ≥ 18 years seen in the HSS rheumatology clinic at least twice between January 15, 2019 and January 14, 2021, with at least one visit occurring between July 15, 2020 and January 14, 2021. MyChart status (active vs. inactive) and sociodemographic and clinical variables were extracted from the electronic health record (EHR). We used chi-square tests and t-tests to compare characteristics between patients with and without active MyChart; p-value <0.05 was considered significant (Table 1). In addition, 10 rheumatology fellows were prompted on 3 occasions over 6 weeks to informally survey their own clinic patients with inactive MyChart accounts by asking: "What is your primary reason for not using MyChart?".Table 1.Baseline Characteristics of Hospital for Special Surgery Rheumatology Clinic Patients Stratified by MyChart Activation StatusMyChart Active (N=726)MyChart Inactive (N=501)p-valueAge, yrs - Mean (SD)50.3 (15.6)60.0 (15.3)<0.01Female - N (%)601 (82.8)412 (82.2)0.80Race - N (%)0.37•White/Caucasian275 (37.9)184 (36.7)•Black/African American185 (25.5)135 (27.0)•Asian58 (8.0)25 (5.0)•Other189 (26.0)145 (28.9)•Unknown18 (2.5)11 (2.2)Ethnicity - N (%)0.27•Hispanic/Latino294 (40.5)226 (45.1)•Not Hispanic/Latino422 (58.1)268 (53.5)•Unknown10 (1.4)7 (1.4)Preferred language - N (%)<0.01•English611 (84.2)332 (66.3)•Spanish72 (9.9)134 (26.8)•Other43 (5.9)35 (7.0)Needs interpreter - N (%)106 (14.6)156 (31.1)<0.01There were 1,227 patients included (93.2% with Medicaid and/or Medicare insurance). Compared to patients with inactive MyChart (42.9%), those with active MyChart (57.1%) were younger (50.3 ± 15.6 vs. 60.0 ± 15.3 years, p<0.01). The majority of patients in both groups was female. There was no significant difference in race or ethnicity between groups. Patients without active MyChart were less likely to identify English as their preferred language and more likely to require an interpreter for clinic visits (Table 1).The rheumatology fellows collectively asked 16 clinic patients with inactive MyChart their primary reason for non-use. The most commonly cited reason was difficulty using the technology (n=8; 50.0%); others included visual impairment (n=2; 12.5%), preference for using the telephone (n=2; 12.5%), concerns about security/spam (n=2; 12.5%), not having a smart phone/computer (n=1; 6.3%), and having a language barrier (n=1; 6.3%).In the HSS rheumatology clinic, patients who did not have active MyChart were older and less likely to be English-speaking than those who did. The most common barrier to MyChart use reported by patients was difficulty with the technology. This pilot data suggests a need for interventions to facilitate patient-provider communication, specifically targeting older and non-English-speaking rheumatology clinic patients, with the goal of advancing patient engagement and health equity.[1]Ancker JS, et al.

This paper analyzes the causes that led to the federal indictment of thirteen female guards, and eventual conviction of forty guards and inmates, at the Baltimore City Detention Center in 2013. The analysis is based on information presented in extensive newspaper coverage during and after the discovery of the events and the behavior at the jail. While popular opinion in the press blamed the guards' gender or their personal morals for their actions, the incident can best be explained through the use of organizational heuristic tools. Application of Diane Vaughan's matrix of routine nonconformity reveals that the guards' actions involved multiple layers of misconduct within an organizational setting and that the failures were not individual but structural.

Tissue factor plays an important role in atherosclerosis.Endothelial cells,monocyte/macrophagy,chemotaxis and migration are all related to tissue factor,which is related to smooth muscle cell proliferation of atherosclerosis and restenosis.


We propose and demonstrate light-in-flight recording by parallel phase-shifting digital holography to obtain a motion picture of ultrashort light pulse propagation free from unwanted images, which are a zeroth-order diffraction image and a conjugate image, by phase-shifting interferometry with a single-shot exposure. We developed a polarization-imaging camera to record the propagation of a femtosecond light pulse whose center wavelength and temporal duration were 800 nm and 96 fs, respectively, and observed the propagation of the pulse without the unwanted images for 10 ps.


Continuous remote monitoring of a patient's health condition in dynamic environment imposes many challenges. Challenges further get multiplied based on the size of body area sensor network. One such challenge is energy efficiency of sensors. Maintaining longer life of all nodes, especially who participate in communicating vital signals from one network to another towards the base station is very important. In this work, an energy efficient communication protocol for the wireless body area network (WBAN) is proposed. The essential characteristics of the protocol are: random deployment of nodes, formation of clusters, node with high signal to noise ratio (SNR) as cluster head (CH), random rotation of CHs within each cluster, and so on. The developed algorithm is simulated in MATLAB by varying the number of nodes and networks. Obtained results are compared with some of the recent and most relevant existing works. It is found that there is an enhancement in the network lifetime by 19.5%, throughput by 12.61% and average remaining energy by 57.21%.

When defining the properties of isotopes we invariably say that the isotopes of an element have the same chemical properties, because they have the same electron shell, but different physical properties, because they have different masses. However, if the behavior of isotopes of any chemical element is scrutinized very closely, small differences are noticeable: in the course of a chemical reaction as in the course of a physical process, isotope ratios vary and isotopic fractionation occurs. Such fractionation is very small, a few tenths or hundredths of 1%, and is only well marked for the light elements, let us say those whose atomic mass is less than 40. However, thanks to the extreme precision of modern measurement techniques, values can be measured for almost all of the chemical elements, even if they are extremely small for the heavy ones. When we spoke of isotope geochemistry in the first part of this book, we voluntarily omitted such phenomena and concentrated on isotope variations related to radioactivity, which are preponderant. We now need to look into the subtle physical and chemical fractionation of stable isotopes, the use of which is extremely important in the earth sciences. Identifying natural isotopic fractionation of light elements The systematic study of the isotopic composition of light elements in the various naturally occurring compounds brings out variations which seem to comply with a purely naturalistic logic. These variations in isotope composition are extremely slight, and are generally expressed in a specific unit, the δ unit .

The Kalman filter is a set of mathematical equations that provides an efficient computational means to estimate the state of a process, in a way that minimizes the mean of the squared error. The filter is very powerful in several aspects: it supports estimations of past, present, and even future states, and it can do so even when the precise nature of the modelled system is unknown. It has several applications such as Noise Cancellation, Tracking, System Identification etc. This book illustrates the use of Kalman filter to remove noise from an erroneous signal. It also defines how Kalman Filter can be used to estimate position and velocity of a moving object. Kalman Filter can also predict position of the object in advance. System Identification is one of the most interesting applications of Kalman Filter. Based on the error signal, the filter''s coefficients are updated and corrected, in order to adapt, so the output signal has the same values as the reference signal. The application enables remarkable developments and research, creating an opportunity for automation and prediction.


A thermodynamic theory of the annealing behavior of Si impurities in GaAs is presented. It is predicted that the ratio of the number of Si impurities at the Ga sites to that at the As sites is sensitive to the stress under which annealing or doping is performed. The ratio is above and below unity under a compressive stress and tensile stress exceeding a critical value, respectively. Therefore, the Si impurities act predominantly as donors and acceptors under the respective stresses. The theory is supported by our experimental finding that the Si‐implanted GaAs becomes of p type by annealing under a tensile stress.


The paper describes a variable speed wind energy conversion scheme where fuzzy logic principles and matrix converter (MC) are used for efficiency optimization and performance enhancement. A squirrel cage induction generator feeds the power to an improved topology of MC which pumps power to a utility grid. The power factor at the interface with the grid is controlled by the MC to ensure purely active power injection into the grid for optimal utilization of the installed wind turbine capacity. Furthermore, the MC to avoid self-excitation capacitors satisfies reactive power requirements of the induction generator. The generation system has fuzzy logic control with vector control in the inner loops. Fuzzy controller tracks the angular frequency with the wind velocity to extract the maximum power and programs the machine flux for light load efficiency improvement. The complete control system has been developed, analyzed, and validated by simulation study.


In this paper,we will explore effects of LT exercise on the protein content and tyrosine phosphorylation of IRS-2 in rats with diabetes.Thirty SD rats were divided into three groups:normal control group(NC,n=10),diabetes mellitus group(DMC,n=10)and exercise group(EXE,n=10)after DM model setting.The exercise groups did the running exercise each day for 50min with the intensity of 20m/min,lasting for six weeks.The content and tyrosine phosphorylation of IRS-2 protein were measured by Western bolt analysis.The results show that the content and tyrosine phosphory-lation of IRS-2 protein in exercise group enhanced up to 24.2%(P0.01)and 37.2%(P0.01)respectively,compared with the DMC group,but still keeping in a lower level compared with the NC group.The results hint that the LT exercise can affect the content and tyrosine phosphorylation of IRS-2 protein in skeletal muscle in DM rats.

TRAIL has been reported to induce apoptosis in a variety of tumor cell types including hepato-cellular carcinoma (HCC) cell lines. However, considerable numbers of HCC cells, especially some highly malignant tumors, show resistance to TRAIL-induced apoptosis. The molecular mechanisms that regulate sensitivity versus resistance of tumor cells to TRAIL-induced apoptosis remain poorly defined. It has been shown that human telomerase catalytic subunit (hTERT) is overexpressed in human HCCs. In this study, we investigated the effects and the mechanisms of hTERT RNAi on the TRAIL-induced apoptosis of HCC cells that exhibit resistance to TRAIL. Our results indicate that hTERT RNAi sensitizes TRAIL-resistant HCC cells to TRAIL-induced apoptosis. hTERT RNAi-mediated sensitization to TRAIL-induced apoptosis is accompanied up-regulation of procaspases-8 and -9, inhibition of telomerase activity and loss of telomere length. Our results suggest that hTERT RNAi overcame the resistance of the HCC cells against TRAIL, at least in part, via the mitochondrial type II apoptosis pathway and telomerase-dependent pathway.


The Cognitive radio (CR) is evolving technology for managing the spectrum bandwidth in wireless network. The security plays a vital role in wireless network where the secondary users are trying to access the primary user's bandwidth. During the allocation the any malicious user either he pretends to be primary user or secondary user to access the vital information's such as credentials, hacking the key, network jam, user overlapping etc. This research paper discusses on various types of attack and to prevent the attack in cognitive radio network. In this research, secondary users are identified by the primary user to access the primary network by the secondary users. The secondary users are given authorization to access the primary network. If any secondary user fails to provide the authorization, then that user will be treated as the malicious user. In this paper two approaches are suggested one by applying elliptic curve cryptography and the other method by using priority-based service access.


The study presents an ethnolinguistic approach to the secular pre-standard literature of the so called Slavia Orthodoxa in its final period. In focus are the methodological aspects of the research. The approach proposed here is based on a philological model developed by the author. The model operates on the text level and includes linguistic and non-linguistic (textological and sociolinguistic) properties of text. It has now been extended to cover the ethnolinguistic factor and is applied to the 17th-18th c. East Slavic and Serbian corpus.


In this paper, we introduce slant submersions from Lorentzian almost paracontact manifolds onto Riemannian manifolds. We give examples and investigate the geometry of foliations which are arisen from the definition of a Lorentzian submersion. We also find necessary and sufficient conditions for a slant submersion to be totally geodesic.

In present work, Variable Angle Spectroscopic Ellipsometer (VASE) is used to determine the optical properties of thermally evaporated thin films Se15Te62.5Ge22.5 and Se10Te67.5Ge22.5 from 0.8 to 5.1 eV. The experimental data of VASE parameters were fit using two group of models to extract the dielectric function. First group consist from mixtures of several Gaussian, and one Tauc–Lorentz (TL group ). The other group is a mixed from several Gaussian and one Cody-Lorentz dispersion functions (CL group). The models' factors such as resonance, optical band gap, Urbach energies, oscillator's amplitude and width for both Se15Te62.5Ge22.5 and Se10Te67.5Ge22.5 films were estimated. Extinction coefficients and refractive indices as function of photon energy of the films were calculated. Both models perform very equally and precisely adequate to the experimental data. However the CL model shows a good accuracy in recounting dielectric function at the beginning absorption area.


The destruction of Beirut's port and large areas of the inner city following the August 2020 explosion occurred amid (and has exacerbated) an unprecedented national economic and social crisis portending another potential phase of urban "reconstruction" and a national political revolution. Critical scholars have highlighted the shortcomings of urban planning and governance in the city after the Lebanese civil war, particularly in terms of housing, infrastructure, and social inequalities, especially between the urban core and periphery. Beirut's post-war reconstruction(s), guided by blended-scale governance (i.e., public/private, confessional/political, national/local) and a real estate-oriented growth model have neither managed to completely restore nor efface the city's erstwhile status as an entrepôt of regional and international economic, cultural, and political importance but have instigated processes of rapid urbanisation and uneven development. These processes, historical trajectories, political and socio-economic dialectics, and shifts in urban political economy render Beirut relevant to the nascent empirical category of "relational cities," i.e., cities whose geographical-historical profiles position them as urban nodes connecting regional-global-national systems of flows under globalised capitalism. This article positions Beirut in the context of the debate on relational urbanisation for empirical exploration, and also points to the evental possibilities for alternative geographies that flow from the October 2019 protests.


New Orleans-Recently introduced upgrades have further enhanced the versatility and safety of the Hansatome (Bausch & Lomb), but users must recognize that deriving the full benefits of this microkeratome depends greatly on its meticulous care, according to Randy J. Epstein, MD, at the refractive surgery subspecial-ty day held prior to the American Academy of Ophthalmol-ogy annual meeting.


Only one bleeding point is typically seen in the local mucosa in most cases of nasal bleeding. We report here a rare epistaxis case suspected of multiple bleeding points on unilateral nasal cavity. A 64-year-old male had a one-week history of chance left-sided epistaxis. Multiple mucosal eruptions were seen on the inferior and middle turbinates and nasal septum of the left nasal mucosae. A dark brown mass was recognized near the frontal recess and removed. This mass was determined to be a live nasal leech. This patient had an history of leech exposure three months earlier while bathing in natural hot spring. Patients with a nasal foreign body usually have symptoms of foul-smelling purulent secretion and nasal stiffness with mucosal swelling. These symptoms are the result of rejection reactions by neutrophills against the foreign body. However, this reported case had no such symptom. This finding was supported that a live leech moves around the nasal cavity to escape human immune reactions.

Formed in the generally cylindrical body a plurality of grooves, each groove of the grooves comprises a first end at a first portion close to or on the generally cylindrical body, generally cylindrical in this or a second end of the body near the second portion, and a transition portion being disposed therebetween.


Objective: To explore the diagnostic value and clinical significance of echocardiogram in noncompaction of ventricularmyocardium(NVM) and to improve the recognition of clinical and ultrasonical examinational doctors on NVM. Methods: The suspicious NVM diagnosed patients were studied by two-dimensional M-mode, echocardiography with various postures and sections. The characteristics of NVM cardiac shape, structures and blood flow changeswere obtained to observe and analyze. Results:Two-dimensional echocardiography showed significant difference between inside and outside at the location of hypokineticmyocardium: the outer layer was relatively thin and appeared as a compact layer with stronger echoes, whereas the inner layer was relatively thicker and appeared as prominent myocardial trabeculations and formation of intertrabeculations recesses deeply stucked in between them in the presence of "honeycomb", which tended to take place at cardiac apex and on sidewall of leftventricle. The enlargement of leftventricle and leftatrium, which could accompany the recesses on locularwall or result in formation of thrombosis in ventricle and atrium. M-mode: echocardiogram showed that the motion amplitude of locularwall at the above-mentioned location was relatively flat and the increase rate of locularwall during the period of contraction descended. The Doppler echocardiogram showed the information that there were visible blood streams within the recesses deeply stuck between myocardial trabeculae and they were connected with left ventricle of heartchamber. The function of heartchamber involved declined. Conclusions: NVM has the manifestation of characteristics ultrasonography, which can be diagnosed at the stage of no obvious symptom in the echocardiogram, so echocardiogram is the most reliable, simple and convenient examination method for diagnosis of NVM.

Violation of trademark right in case of registered trademark it is infringement and in case of unregistered trademark it will be passing off.  Injunction, damages and account for profit are the remedies available for violation of trademark rights in India. Now India trademarks are governing under Indian Trade Mark Act, 1999.


Quercetin compounds which are one of the most active compounds in many flavonoids have a strong efficacy efficacy in medicine. Two quercetin flavonoids isorhamnetin and isorhamnetin⁃3⁃O⁃glucoside are selected as the target compounds, and Gaussian 09 software and the density functional theory (DFT) method are used to study on antioxidant activity of isorhamnetin and isorhamnetin⁃3⁃O⁃glucoside from the total energy, the dissociation enthalpy of H⁃O bond (BDE), the front molecular orbital and the energy level and atomic net charge. The results show the activity of isorhamnetin was greater than isorhamnetin isorhamnetin⁃3⁃O⁃glucoside, and the loss of hydrogen by the phenolic hydroxyl groups at the 4􀆳position is the greatest for the two types molecules antioxidant activity overall, phenolic hydroxyl in this position shows obvious high activity characteristics. Although the glycosides do not have the effect of eliminating free radical activity, it is not involved in the formation of frontier molecular orbitals, and it has a great impact on the polarity of the molecule itself, can change the molecular solubility in the body and absorbance. The study provides further scientific basis for the further study on the antioxidant activity of quercetin flavonoids and the improvement of antioxidant structure.


The number of cancer patients has been increased to a great extent over last few years in Bangladesh. National Institute of Cancer Research and Hospital (NICRH) has confirmed more than 27,000 cancer patients from year 2008-2010. However, the number of researches on cancer patients are limited in the context of Bangladesh. This research aims to explore the key factors that have relationship with cancer. The factors include different demographic and occupational information as well smoking habits of patients. We have generated two adaptive neuro fuzzy inference system (ANFIS) models, one for female and one for male patients of Bangladesh and reported the relationships of different factors with five top malignancies reported in NIRCH data set.


Silastic intubation was performed for Canaliculus communis obstruction in 32 cases. Two eyes showed additional impatent nasolacrimal duct and were not treated. The silastic intubation was performed by aid of a long, hollow blunt injection needle which allows us to check the patency of the lacrimal system once the stenosis of common canaliculus is perforated. The success rate for isolated silastic intubation was 70%, which is similar to the results of other often more invasive surgical techniques for Canaliculus communis stenosis.


Synthesis gas fermentation is a microbial process, which uses anaerobic bacteria to convert CO-rich gases to organic acids and alcohols and thus presents a promising technology for the sustainable production of fuels and platform chemicals from renewable sources. Clostridium carboxidivorans and Clostridium autoethanogenum are two acetogenic bacteria, which have shown their high potential for these processes by their high tolerance toward CO and in the production of industrially relevant products such as ethanol, 1-butanol, 1-hexanol, and 2,3-butanediol. A promising approach is the coupling of gasification of biogenic residues with a syngas fermentation process. This study investigated batch processes with C. carboxidivorans and C. autoethanogenum in fully controlled stirred-tank bioreactors and continuous gassing with biogenic syngas produced by an autothermal entrained flow gasifier on a pilot scale >1200 °C. They were then compared to the results of artificial gas mixtures of pure gases. Because the biogenic syngas contained 2459 ppm O2 from the bottling process after gasification of torrefied wood and subsequent syngas cleaning for reducing CH4, NH3, H2S, NOX, and HCN concentrations, the oxygen in the syngas was reduced to 259 ppm O2 with a Pd catalyst before entering the bioreactor. The batch process performance of C. carboxidivorans in a stirred-tank bioreactor with continuous gassing of purified biogenic syngas was identical to an artificial syngas mixture of the pure gases CO, CO2, H2, and N2 within the estimation error. The alcohol production by C. autoethanogenum was even improved with the purified biogenic syngas compared to reference batch processes with the corresponding artificial syngas mixture. Both acetogens have proven their potential for successful fermentation processes with biogenic syngas, but full carbon conversion to ethanol is challenging with the investigated biogenic syngas.


ABSTRACT A new procedure to determine copper has been proposed using an irreversible and disposable multilayer optical test strip. Two layers form the sensing zone: a copper sensitive and a dialysis layer. The test strip is characterised to be a disposable polyester sheet contained in a circular film 6 mm in diameter and 25 µm in thickness, with all reagents necessary to produce a selective response. The sensing zone was formed by Nafion as polymer, bathocuproine as a chromogenic reagent and p-anisidine as reducer. When it is applied to determination of copper in plasma samples, another layer of hydrogel D-6 is put on this membrane to eliminate the interference of proteins. When the test strip was introduced for 60 min into a plasma sample an orange colour developed. The absorbance at 475 nm was used as the analytical signal. The test strip responded linearly in the range 0.05–1.00 mg L−1. The reproducibility in the measurement of copper at 3.0 mg L−1, was 7.8%. The procedure was applied to the determination of copper in different samples of plasma validating results against a reference method used in clinical laboratory. The method is simple, inexpensive, selective and sensitive.


To provide reliable and high quality power for critical loads in all grid conditions, Uninterruptible Power Supplies (UPS) are widely used. A non-isolated online uninterruptible power supply (UPS) system is proposed in this paper. This system consists of bridgeless PFC boost rectifier, battery charger/discharger, and an inverter. A new battery charger/discharger has been implemented which ensures the bidirectional flow of power between dc-link and battery bank, reducing the battery bank voltage to only 24V, and regulates the dc-link voltage during battery power mode. Operating batteries in parallel improves the battery performance and resolve the problems related to conventional battery banks that arrange batteries in series. The output voltage for both linear and non-linear loads regulating system is proposed which contains a new control method, integrating slide mode and proportional-resonant control, for inverter. The controller exhibits excellent performance during transients and step changes in load. Operating principle and experimental results of 1kVA prototype have been presented for validation of the proposed system.


In this study, the influences of nitrogen (N2) and hydrogen (H2) gases on the physicochemical and textural properties of yogurt during storage were investigated.
The redox potential of the environment has been changed by using N2 and H2 which are natural methods that do not have a toxic effect on milk used in yogurt. In this way, it was determined how these reducing media changed compared to the control yoghurt. Especially H2 has made yogurt more functional with its non-toxic antioxidant feature. Redox potential is the quality parameter that affects the properties of yoghurt. The effects of this parameter on yoghurt have been revealed during storage. It has been determined in this study that quality control can be achieved by determining the effects of this quality parameter in the yoghurt process


Much of the literature on the usefulness of company financial statement information focuses on the United States and the United Kingdom. But, these two countries are characterized by similar and rigid regulatory and enforcement regime. This study provides direct evidence from the Netherlands – a country with liberal financial reporting environment and different corporate governance regime. It empirically examines the information content of annual and semi-annual earnings announcements and the long-term association between stock returns and some widely reported financial statement variables. The evidence suggests that earnings and dividends disclosures made by Dutch companies are useful to stock market investors and the extent of the usefulness is not that modest as often perceived. However, the Dutch practice of reporting accounting cash flows as a summary performance measure does not have significant incremental usefulness.


Cloud computing provides storage for multiple users to store and share their data in different places. In Cloud computing, Datacenter plays a requisite role in storing a vast amount of data. At the time of discrepancies, access to large data sets of is very difficult. Hence, Data Replication is preferred in handling the huge volumes of data (i.e.) the necessary files are replicated and stored in nearby locations of users which reduces the execution time and ensures data availability. The proposed Dynamic Popularity aware Data Replication algorithm accelerates the data access time by reducing the latency.


PurposeThe purpose of this study is to propose a data-driven perspective to analyze enterprise information system (EIS) feature use for understanding what and how the system features are actually used in the organization.Design/methodology/approachAn empirical study was conducted by analyzing information system (IS) log data collected from a well-known shipbuilding manufacturer in China. The multiple analytical approach employed in this study includes social network analysis, association rules learning and human dynamics.FindingsThis study first classified IS users into 41 core users and 325 general users. Then 24 core modules and 54 general modules were identified by social network analysis, and the correlation between them was analyzed. Finally, we found that the IS use time intervals for different user groups followed a power-law distribution, and IS use displayed strong burstiness and weak memory.Originality/valueThis study proposes a data-driven perspective to investigate how the system features are actually used in the organization. This study contributes to the literature and opens a new avenue for future IS use research. Furthermore, this study informs managers how to diagnose, maintain and optimize the implemented IS in order to maximize IS benefits.

The anterior capsulolabralcomplex repair with inferior glenohumeral ligament reconstruction has been encouraging predominantly in young active population, and heavy workers with traumatic anterior shoulder dislocation. The aim of this study was to assess the clinical outcome of patients who underwent inferior glenohumeral ligament reconstruction for recurrent traumatic anterior shoulder instability by the open method. A prospective study of 40 patients with a mean age of 30 years ( 20 – 50 years ) who underwent open reconstruction of the inferior glenohumeral ligament ( RIGHL) to treattraumatic recurrent anterior shoulder dislocation was conducted. All patients met the criteria for inclusion in the study. They had traumatic anterior shoulder dislocation with subsequent recurrent instability. All were males with no professional athletes among them. Detachment of the dominant shoulder from the glenoid marginwas found in all cases . No patient had surgical intervention before. Twenty patients had the right shoulder affected. All patients were evaluated by physical examination and followed for a minimum of 6 months (15-80 months). Rowe score was used for the clinical assessment of patients. The mean modified Rowe score was 93.3% (65% -100%) with 92.3% good and excellent results. There were 14 excellent, 10 good, 5 fair, and 3 poor results due to redislocation after major trauma ( RTA). There was no loss of range of motion compared to preoperative values. These observations point out that glenoid sided capsulolabral repair can reestablish shoulder stability in patients with recurrent traumatic anterior dislocation, and success rates comparable to those of other open anterior shoulder repair procedures can be achieved. Although arthroscopic repair for recurrent shoulder instability is a choice for most surgeons nowadays, open repair remains an excellent option and should not be forgotten especially with the lack of experience or arthroscopic availability.


We report a case of cutaneous leishmaniasis caused by Leishmania guyanensis with sporotrichoid lymphocutaneous dissemination of the parasite and thrombophlebitic complication in a 32‐year‐old man who had recently travelled to French Guiana. After initial failure of empirical treatment with amphotericin B, the patient evolved favourably on high doses of intramuscular injections of meglumine antimoniate for 2 months. This case illustrates the existence of lymphocutaneous forms and possible thrombophlebitic complications of leishmaniasis. It also highlights the challenges in the management of leishmaniasis, despite the existence of guidelines and a wide therapeutic arsenal.


Includes descriptive metadata provided by producer in MP3 file: "A Vanderbilt corporate law scholar believes the President's social security reform plan comes at a dangerous time for low and middle-class employees. Listen to an interview with Professor of Law Margaret Blair." Blair warns that private accounts as proposed by President Bush would create additional risk for employees at a time when employers are moving away from defined benefit plans towards defined contribution plans. Blair believes that a number of adjustments to the current program could eliminate the program's deficit by 2050.


In recent years the role of psychological assessment has gained prominence within hospitals, especially with cancer patients. Thus, the present study aims to describe through theoretical contributions within the psychology of contributions, peculiarities and possibilities with surgical patients diagnosed with breast cancer. In this sense, descriptions were made regarding breast cancer, surgical process, and the psychosocial impacts generated by breast cancer in women. Based on these notes, the final considerations are guided to consider the importance of monitoring and psychological support, the carriers of breast cancer, from diagnosis until the end of treatment. Also, it emphasized the need for more space for the Psychology performance in this context and in particular the hospital setting.


This study attempts to examine the response of stock markets amid the COVID-19 pandemic on prominent stock markets of the BRICS nation and compare it with the 2008 financial crisis by employing the GARCH and EGARCH model. First, average and variance of stock returns are tested for differences before and after the pandemic, t-test and F-test were applied. Further, OLS regression was applied to study the impact of COVID-19 on the standard deviation of returns using daily data of total cases, total deaths, and returns of the indices from the date on which the first case was reported till June 2020. Second, GARCH and EGARCH models are employed to compare the impact of COVID-19 and the 2008 financial crisis on the stock market volatility by using the data of respective stock indices for the period 2005–2020. The results suggest that the increasing number of COVID-19 cases and reported death cases hurt stock markets of the five countries except for South Africa in the latter case. The findings of the GARCH and EGARCH model indicate that for India and Russia, the financial crisis of 2008 has caused more stock volatility whereas stock markets of China, Brazil, and South Africa have been more volatile during the COVID-19 pandemic. The study has practical implications for investors, portfolio managers, institutional investors, regulatory institutions, and policymakers as it provides an understanding of stock market behavior in response to a major global crisis and helps them in taking decisions considering the risk of these events.


From formulas derived for the efficiency of atomic power stations, it is shown that when the temperature of the fuel elements is increased the temperature of the work fluid and the effective efficiency of the station increase. The temperature of the working fluid increases rather slowly, but the effective efficiency increases rapidly. When the reactor temperature is increased to twice its initial value, the temperature of the working fluid increases 40% while the efficiency is almost doubled. (J.S.R.)


This paper described a simple novel technique to prepare magnetic nano-composite particles coated with highly crosslinked poly(lauryl methacrylate) (PLMA), a hydrophobic polymer because of its long chain alkyl group for application in waste water purification. Nano-sized magnetite (Fe3O4) particles prepared by coprecipitation of Fe2+ and Fe3+ from their alkali aqueous solution were encapsulated with SiO2 following treatment with tetraethylorthosilicate (TEOS). Finally precipitation copolymerization of LMA and divinyl benzene (DVB) in the presence of Fe3O4/SiO2 particles was carried out within stable isolated droplets containing hexadecane–toluene mixture (4:1 mixture HD-T). The produced PLMA-coated magnetic composite particles named as Fe3O4/SiO2/P(LMA-DVB) were characterized by Fourier Transform IR (FTIR), transmission electron microscopy (TEM), thermogravimetry (TG) and X-ray diffractometer (XRD) analyses. The performance of the composite particles was evaluated for the removal of organic pollutants from water. Copyright © 2015 John Wiley & Sons, Ltd.


For almost fifteen years I have been involved in projects that aim to explore the ever-expanding variety of work produced by contemporary British women poets. As someone who lives and works in Romania, at the other end of Europe from the United Kingdom, I have devised my investigation of this present-day creative flowering from an outsider's perspective. And for specific purposes: to increase academic and public interest in the kaleidoscope of themes and motifs approached by the poets, to contribute to the creation of a cultural bridge across the Continent, and to promote contemporary British women's poetry by emphasising its singular character within the European cultural milieu. My current research interest focuses on examining the concept of 'Londonness' and the alternative identities forged by the unrivalled metropolis from the viewpoint of 'the situatedness of selfhood', a phrase coined by literary critic Romana Huk to highlight the paramount importance of place in the construction of the self. What follows is a personal account


The trophic ecology of Octopus vulgaris paralarvae collected in 2008 off the Rı́a de Vigo, NW Spain (42 12.800 N–9 00.000 W), was approached by both morphological and molecular methods. External digestion of prey and posterior suction of the liquefied contents by wild O. vulgaris paralarvae made the morphological identification of gut contents impossible. Thus, a PCRbased method using group-specific primers was selected to identify prey consumed by O. vulgaris paralarvae in the pelagic realm. The mitochondrial ribosomal 16S gene region was chosen for designing group-specific primers, which targeted a broad range of crustaceans and fishes but avoided the amplification of predator DNA. These primers successfully amplified DNA of prey by using a semi-nested PCR-based approach and posterior cloning. Homology search and phylogenetic analysis were then conducted with the 20 different operational taxonomic units obtained to identify the putative organisms ingested. The phylogenetic analysis clustered ingested prey into 12 families of crustaceans (11 belonging to the order Decapoda and 1 to the order Euphausiacea) and two families of fishes (Gobiidae and Carangidae). According to the Czekanowski's Index (CI), the trophic niche breadth of O. vulgaris paralarvae is low (CI = 0.13), which means that these paralarvae are specialist predators at least during the first weeks of their life cycle. It is the first time that natural prey has been identified in O. vulgaris paralarvae collected from the wild, and such knowledge may be critical to increasing the survival of O. vulgaris hatchlings in captivity, a goal that has been actively pursued since the 1960s by aquaculture


Background and Purpose Alzheimer's disease (AD) pathogenesis involves amyloid-β (Aβ) aggregation where the intermediate oligomers are considered the prime toxic species. Here, we aimed to identify an effective peptide sequence from a medicinal plant-derived enzyme having anti-amyloidogenic properties against Aβ. Experimental Approach LC-MS/MS followed by computational analysis identified the active peptide (termed here as Pactive). Visualization techniques along with biophysical and biochemical approaches were used to determine the anti-amyloidogenic potency of the purified enzyme and peptides identified from the enzyme. Cytotoxicity was measured on SHSY-5Y cell lines. Interaction studies were done with bio-layer interferometry (BLI) and bio-stability of the peptide was assessed by NMR. Pactive induced conformational alterations of Aβ monomer and oligomers was determined with DSC and NMR. Key Results A small heptameric peptide (Pactive) identified form a medicinal plant-derived fibrinolytic enzyme proved to be a multifunctional inhibitor against Aβ aggregation. The results suggested that Pactive arrests Aβ molecules in non-toxic off-pathway oligomers that can no longer participate in the cytotoxic fibrillation pathway. Mechanistically, Pactive binding induces conformational alterations in the Aβ molecule, thus modulating its hydrophobicity, one of the key players in inducing aggregation. Conclusions and Implications The study identified a natural peptide Pactive (GFLLHQK) that displays potential anti-amyloidogenic properties against Aβ aggregation. The bio-stability of Pactive in human blood serum as well as its non-toxic nature makes it a promising therapeutic candidate against Alzheimer's, for which no disease-modifying treatments are available till date.


Nosocomial infection is one of the most serious healthy problem in the world. It causes by Pseudomonas aeruginosa which has a high resistance to antibiotic. One alternative to overcome this problem is the utilization of chocolate (Theobroma cacao) because it contains polifenol that can be used as an antibacterial agent. The aim of this research was to determine antibacterial effect and Minimum Inhibitory Concentration (MIC) of ethanolic extract of cocoa beans to P. aeruginosa by in vitro method. Antibacterial activity test used disk diffusion (Kirby Bauer) method. This type of research was a quasi-experimental with posttest only control group design. Samples used was colony of P. aeruginosa. Concentrations of test solution used were 7,81; 15,62; 31,25; 62,50; 125; 250; 500; and 1000 mg / ml. Positive control used cefepime suspension and negative control used sterile distilled water. The result showed that inhibition zones formed at a concentration of 7,81 mg/ml to 1000 mg/ml. The higher the concentration of the cocoa beans extract, the wider the inhibition zones formed. By direct measurement, MIC was obtained at the dose of 7.81 mg / ml while statistical analysis yielded an MIC value of more than 6.95 mg / ml. In conclusion, the ethanolic extract of cocoa beans had antibacterial effect on P. aeruginosa in vitro. Keywords: antibacterial effect, cocoa beans, Pseudomonas aeruginosa


Let p be a prime and q = pm. We investigate permutation properties of polynomials P(x) = xr + xr+s + ⋯ + xr+ks (0 < r < q - 1, 0 < s < q - 1, and k ≥ 0) over a finite field 𝔽q. More specifically, we construct several classes of permutation polynomials of this form over 𝔽q. We also count the number of permutation polynomials in each class.


The following discussion has its genesis in a study by this author of the supposed terrorist threat to shipments of nuclear materials by sea (and particularly on dedicated ships), which examined a wide range of imagined scenarios with a view to determining their plausibility in the context of what is known about the security arrangements that attend such shipments. Broadly, it was concluded that the likelihood of an attack of the kind envisaged resulting in a significant release of radioactive material was extremely small. Equally, it was noted that all recent examples of interference (or attempted interference) with the transportation of nuclear materials (both maritime and overland) had involved the activity of protest groups, rather than that of persons seriously intent on diversion or theft, or the deliberate release of radioactive material.


In this paper, the control-Volume Lattice Boltzmann Method (CVLBM) is adopted to solve transient heat and mass transfer in a LaNi5- H2 reactor during the desorption process. The numerical simulation was used to present the temporal evolution of the temperature and the hydrogen mass desorbed and the isotherms. In order to verify the validity of the numerical approach, the obtained results were compared firstly with those of the literature [18] and then with those of the unstructured CVFEM. We found that the CVLBM accurately predicts hydrogen desorption phenomena and has less CPU time than the CVFEM.
